  • Clinical outcomes of vitrectomy with internal limiting membrane peeling and air tamponade in the treatment of idiopathic macular hole

    ObjectiveTo observe the clinical effect of vitrectomy with internal limiting membrane peeling and air tamponade in the treatment of idiopathic macular hole (IMH).MethodsA prospective, non-randomized controlled case cohort study. Twenty eyes of 20 patients with IMH in Ophthamology Department of The Second Hospital of Jilin University from September 2016 to January 2017 were included in this study. There were 4 males (4 eyes) and 16 females (16 eyes), with the mean age of 60.60±9.50 years and the mean disease course of 9.55±15.5 months. The stage of macular hole ranged from Ⅱ to Ⅳ. All patients underwent BCVA, intraocular pressure, spectral-domain OCT (SD-OCT) and multifocal ERG examinations. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logMAR visual acuity. The minimum diameter (MIN), bottom diameter (BD), height (H), the defective diameter of ellipsoid zone, the defective diameter of external limiting membrane (ELM) of the macular hole were measured by SD-OCT (German Heidelberg). Then the macular hole index (MHI=H/BD), hole traction index (THI=MD/BD) and hole diameter index (DHI=H/MD) were calculated. The response density in P1 wave was detected by mf-ERG. The logMAR BCVA was 1.18±0.54. There were 5 eyes with less than 400 μm MIN, 13 eyes with 400-700 μm MIN and 2 eyes with over than 700 μm MIN. All the patients were underwent vitrectomy with internal limiting membrane peeling and air tamponade. According to the SD-OCT image features after surgery, IMH closure was divided into type Ⅰ closed, type Ⅱ closed and unclosed. The follow-up was equal or greater than 3 months. The closure rate of IMH, BCVA and the changes of microstructure parameters of macular area were observed. Spearman correlation analysis was used to analyze the correlation between BCVA and the wave response density in P1 before surgery and the efficacy after IMH surgery.ResultsClosure rate of IMH: 18 eyes (90.0%) were completely closed (all type Ⅰ closed). The closure rate of macular hole with the MIN less than 400 μm was 100.0% (5/5), 400-700 μm was 92.3% (12/13), and over than 700 μm was 50% (1/2). BCVA: the mean logMAR BCVA at 1 week, 1 month, 3 months after surgery were 0.83±0.54, 0.65±0.41, 0.48±0.34, and there was statistically significant difference between preoperative and postoperative BCVA (t=3.382, 4.459, 5.250; P=0.003, 0.007, 0.004). The outcomes of SD-OCT at 3 months after surgery: 18 eyes (90.0%) with intact ELM. The defective diameter of ellipsoid zone was 260.34±272.08 μm, there was statistically significant difference between before and after surgery (t=13.545, P=0.002). The outcomes of mf-ERG: the P1 wave response density of the ring 1 and ring 2 after surgery were increased compared with before surgery (t=-16.748, -6.151; P<0.01,<0.01). The results of Spearman correlation analysis: there was a positive correlation between postoperative BCVA and preoperative MIN, the defective diameter of ellipsoid zone and ELM, and postoperative the defective diameter of ellipsoid zone (r=0.56, 0.59, 0.68, 0.52; P=0.010, 0.006, 0.001, 0.019). The postoperative BCVA was negatively correlated with the P1 wave response density of ring 1 and ring 2 of mf-ERG (r=-0.34, -0.16; P=0.006, 0.020). The IMH closure had a significant negative correlation with MIN and the defective diameter of ELM (r=-0.449, -0.449; P=0.047, 0.047). MHI and THI were positively correlated with the closure of the hole (r=0.474, 0.546; P=0.035, 0.013). Intraocular pressure increased in 2 eyes during the follow-up period, and returned to normal within 1 week after the administration of antihypertensive drugs. There were no complications during or after the operation.ConclusionsVitrectomy with internal limiting membrane peeling and air tamponade in the treatment of IMH is safe and effective. The MIN, MHI THI are significantly correlated with the curative effect after IMH surgery, which could be used as the index to predict and evaluate the curative effect. The response density of ring 1 and ring 2 in P1 wave of mf-ERG is signifi-cantly improved compared with before surgery, and which is negatively correlated with BCVA.

    ObjectiveTo explore the risk factors influenced postoperative complications of colon cancer. MethodsIn this study, 114 patients diagnosed definitely as colon cancer were enrolled from January 2009 to April 2010 in this hospital. The patients were divided into the complication group and non-complication group according to the occurrence of postoperative complications during hospital day. Furthermore, clinicopathological features and operative parameters of patients were compared in two groups, and independent factors for postoperative complications were identified by multiple regression analysis. ResultsThere were statistical differences between two groups in operation time (t=2.034, P=0.032), diabetes mellitus (χ2=5.920, P=0.015), differentiation degree of tumor (χ2=7.163, P=0.028), hospital stay (χ2=0.411, P=0.026), and ASA grades (χ2=11.585, P=0.009). The morbidity of patients with operative time gt;200 min was significant higher than that ≤100 min (χ2=8.884, P=0.003) and 100-200 min (χ2=7.318, P=0.007). The morbidity of patients with ASA Ⅳ grade was higher than that with ASA Ⅰ grade (χ2=13.426, P=0.000). For tumor differentiation, the morbidity of patients with well-differentiated tumor was higher than that with moderately differentiated tumor (χ2=4.950, P=0.026) and poorly differentiated tumor (χ2=7.476, P=0.006). The hospital stay (P=0.009), age (P=0.024), diabetes mellitus (P=0.018), and ASA grade (P=0.001) were the independent factors for postoperative complications by multivariate regression analysis. ConclusionThe physical quality indexes are the mostly common risk factors of postoperative complications for colon cancer, emphasizing on the high-risk factors and making a targeted and individual treatment plan for each patient are of great important to improve the prognosis.

  • Analysis of influencing factors related to the prognosis of visual acuity on myelin oligodendrocyte glycoprotein antibody positive optic neuritis after methylprednisolone pulse

    ObjectiveTo analyze the prognostic factors of vision of myelin oligodendrocyte glycoprotein (MOG) antibody positive associated optic neuritis (ON) after methylprednisolone pulse therapy. MethodsA clinical observational study. A total of 32 patients (47 eyes) with MOG antibody positive ON were observed and followed up in the ophthalmology department of Beijing Tongren Hospital Affiliated to Capital Medical University and Beijing Puren Hospital from March 2019 to January 2022. Clinical data including the best corrected visual acuity (BCVA) and orbital magnetic resonance imaging were recorded. The BCVA was examined by Snellen visual acuity chart, which was finally converted into the logarithm of the minimal angle of resolution (logMAR) for statistical analysis. There were 22 case (38 eyes) with complete image data. All patients were treated with intravenous methylprednisolone pulse (IVMP) for 3-5 days. According to the intervention time (from onset to glucocorticoid treatment), the patients were divided into three groups: <7 d group, 7-14 d and >14 d group, with 16, 13, 11 eyes, respectively. The median follow-up time was 28 months. After 1 week, 1, 3 and 6 months treatment, the same equipment and methods were used for relevant examinations to observe the changes of visual acuity and the factors influencing the prognosis of visual acuity after IVMP treatment. Logistic regression and linear regression were used to analyze the prognostic correlation factors. Receiver operating characteristic (ROC) curve was used to determine the critical cut-off point of intervention timing. ResultsAmong the patients, 16 were male and 16 were female. The median onset age was 26 years. The onset duration time was 5-60 days. There were 18 cases (56.3%, 18/32) with abnormal serum immune indexes. The initial symptom was decreased vision with unilateral or bilateral ON. Seventeen (53.1%, 17/32) cases had unilateral ON and 15 (46.9%, 15/32) cases with bilateral ON. Thirty-six eyes (76.6%, 36/47) got optic disc edema, 37 eyes (78.7%, 37/47) accompanied by pain of ocular movement. The nadir logMAR BCVA was mean 1.69±0.13. Long T2WI signals with segmental thickening in the orbital segment of the optic nerve were obtained in 27 eyes (71.1%, 27/38) and in 24 eyes (63.2%, 24/38) with optic nerve and sheath enhancement. During the follow-up period, there were 10 cases of relapse (31.3%, 10/32). The logMAR BCVA of attacked eyes were 0.52±0.09, 0.22±0.06, 0.12±0.06, 0.10±0.06 at 1 week and 1, 3 and 6 months after IVMP treatment, respectively. The rate of BCVA improvement was the fastest at 1 week after treatment, and BCVA returned to stability at 3 months. Logistic regression analysis showed that the timing of intervention was significantly correlated with the prognosis of vision in primary onset patients (odds ratio=12.17, P=0.006), with a negative linear regression relationship (r=-0.48, 95% confidence interval -0.71--0.17, P=0.008). Comparing the logMAR BCVA between the intervention time >14 group with the <7 group and the 7-14 group, there were statistically significant difference (P=0.017, 0.037), respectively. The cut-off point of ROC curve to predict the optimal intervention time was 13.5 days. Other factors such as: gender, age, predisposing factor, pain of eye motion, edema of optic disc, bilateral ON, imaging changes, abnormal autoimmune indicators were not associated with the prognosis of visual acuity. ConclusionThe timing of hormone intervention in primary onset patients is an important factor affecting the prognosis of vision and the optimal intervention time window of IVMP is two weeks.

  • Analysis of factors affecting the visual outcome after vitrectomy for idiopathic macular hole

    ObjectiveTo investigate the factors correlated with the visual outcome of idiopathic macular holes (IMH) after vitreoretinal surgery. MethodsA total of 57 eyes of 57 patients with IMH were included. There were 43 females (43 eyes) and 14 male (14 eyes), mean age was (60.46±4.79) years. All the eyes underwent best corrected visual acuity (BCVA), slit-lamp microscope, three-mirror contact-lens and optical coherence tomography (OCT) examinations. BCVA were examined with interactional visual chart and recorded with logarithm of the minimum angle of resolution (logMAR) acuity. The minimum diameter and base diameter of macular holes and central retinal thickness (CRT) were detected by OCT. The average logMAR BCVA of 57 eyes was 0.98±0.41. The minimum diameter and base diameter of macular holes were (479.53±164.16) μm and (909.14±278.65) μm. All the patients underwent pars plana vitrectomy combined with phacoemulsification cataract extraction and intraocular lens implantation. The mean follow-up period was (173.44±147.46) months. The relationships between final BCVA and these parameters were examined by single and multiple regression analysis. The valuable influence factors were filtrated and formulated using multiple linear regression models. ResultsAt the final follow-up, the logMAR BCVA of 57 eyes was 0.44±0.31, the CRT was (158.79±86.96) μm. The final BCVA was positive related to minimum diameter of macular holes and preoperative BCVA (r=0.420, 0.448; P=0.001, 0.000), negative related to postoperative CRT (r=-0.371, P=0.004). There was no relationship between the final BCVA and base diameter of macular holes, age and follow-up (r=0.203, -0.015, 0.000; P=0.130, 0.913, 0.999). The incidence of preoperative BCVA for postoperative BCVA was bigger than preoperative minimum diameter of macular holes (P=0.008, 0.020). ConclusionThe preoperative minimum diameter of macular holes and BCVA are related to postoperative BCVA in IMH eyes.

  • Observation of patient clinical outcomes based on the new subclassification of zone Ⅲ open-globe injury

    ObjectiveTo compare and observe the visual acuity and ocular anatomical outcome of different subtypes in open-globe injury (OGI) Ⅲ. MethodsA retrospective study. A total of 187 eyes of 187 patients with OGI involving zone Ⅲ who were admitted to the Department of Ophthalmology of The First Affiliated Hospital of Army Medical University from January 2020 to December 2023 were included in the study. According to the 2022 International Globe and Adnexal Trauma Epidemiology Study groups consensus, zone Ⅲ was further divided into Ⅲa zone (5-8 mm posterior to the limbus) and Ⅲb zone (>8 mm posterior to the limbus), with 58 eyes (31%, 58/187) in group Ⅲa and 129 eyes (69%, 129/187) in group Ⅲb. Best corrected visual acuity (BCVA) was examined using the international standard decimal visual acuity chart, converted into the logarithm of the minimum angle of resolution (logMAR) visual acuity when recorded. The injured zone, initial visual acuity, final visual acuity, retinal detachment (RD), uveal prolapse, and proliferative vitreoretinopathy (PVR) were collected. The follow-up time after surgery ≥ 6 months. The final visual acuity and anatomical prognosis of the two groups were observed. Silicone oil dependence, phthisis, and enucleation were defined as poor anatomical outcomes. Multiple linear regression analysis was performed to analyze the impact of zone Ⅲb of OGI on the final visual acuity. ResultsAt the 6-month follow-up, the logMAR BCVA of group Ⅲa and group Ⅲb was 1.49±1.0 and 2.51±0.85; there was a statistically significant difference in the logMAR BCVA between the two groups (t=−2.736, P<0.05). Compared with group Ⅲa, the proportion with light perception in group Ⅲb was higher, and the proportions with visual acuity of hand movement, counting fingers, and >0.01 were lower, and the differences were all statistically significant (P<0.05). Compared with group Ⅲa, RD and PVR were more likely to occur in group Ⅲb, and the differences were all statistically significant (χ2= 16.696, 8.697; P<0.05). Among the affected eyes in group Ⅲa and group Ⅲb, there were 14 eyes (24.1%, 14/58) and 95 eyes (73.6%, 95/129) with poor final anatomical outcomes respectively; the incidence of poor final anatomical outcomes in group Ⅲb was higher, and the difference was statistically significant (χ2= 40.332, P<0.01). The results of multiple linear regression analysis showed that initial visual acuity, RD, and uveal prolapse were independent risk factors affecting the final visual acuity (odds ratio=2.407, 4.162, 3.413; P<0.05). ConclusionsPatients with OGI in zone Ⅲb have a worse visual prognosis and a higher incidence of poor anatomical outcomes. The subclassification of zone Ⅲ is helpful for better predicting the prognosis of OGI clinically.

  • Analysis of clinical characteristics and death risk factors in patients with community-acquired pneumonia and sepsis

    Objective To investigate the clinical characteristics and death risk factors of patients with community acquired pneumonia and sepsis. Methods Data of 350 patients with community-acquired pneumonia and sepsis admitted to the Intensive Care Unit of Third Xiangya Hospital of Central South University from January 2015 to October 2021 were retrospectively analyzed, and their basic characteristics, laboratory results and treatment were analyzed. Results The absolute value of white blood cell, neutrophil ratio, absolute value of neutrophil, inflammatory index, liver and kidney function, coagulation function, cardiac enzymology, lactic acid and sequential organ failure evaluation score of patients with community acquired pneumonia sepsis in the non-survival group were higher than those in the survival group. Logistic regression analysis showed that respiratory rate, heart rate, mean arterial pressure, blood oxygen saturation, C-reactive protein, D-dimer, lactic acid, creatinine and lymphocyte ratio may be independent risk factors for 28-day death in patients with community-acquired pneumonia and sepsis.The receiver operating characteristic curve shows that the combination of the above indicators to predict the risk of death of patients has the best sensitivity, specificity and maximum area under the curve, which is superior to the prediction value of individual variables. Conclusions Patients in the non-survivor group of community-acquired pneumonia sepsis had more severe inflammatory response and organ function impairment. Respiratory rate, heart rate, mean arterial pressure, blood oxygen saturation, C-reactive protein, D-dimer, lactic acid, creatinine, lymphocyte ratio and other indicators are independent risk factors for death of patients with community-acquired pneumonia and sepsis, which have better prognostic value when combined.

  • Development and validation of a nomogram model for predicting knee function improvement in early postoperative period after total knee arthroplasty

    Objective To develop and validate a nomogram prediction model of early knee function improvement after total knee arthroplasty (TKA). Methods One hundred and sixty-eight patients who underwent TKA at Sichuan Province Orthopedic Hospital between January 2018 and February 2021 were prospectively selected to collect factors that might influence the improvement of knee function in the early postoperative period after TKA, and the improvement of knee function was assessed using the Knee Score Scale of the Hospital for Special Surgery (HSS) at 6 months postoperatively. The patients were divided into two groups according to the postoperative knee function improvement. The preoperative, intraoperative and postoperative factors were compared between the two groups; multiple logistic regression was performed after the potential factors screened by LASSO regression; then, a nomogram predictive model was established by R 4.1.3 language and was validated internally. Results All patients were followed up at 6 months postoperatively, and the mean HSS score of the patients increased from 55.19±8.92 preoperatively to 89.27±6.18 at 6 months postoperatively (t=−40.706, P<0.001). LASSO regression screened eight influencing factors as potential factors, with which the results of multiple logistic regression analysis showed that preoperative body mass index, etiology, preoperative joint mobility, preoperative HSS scores, postoperative lower limb force line, and postoperative analgesia were independent influencing factors for the improvement of knee function in the early postoperative period after TKA (P<0.05). A nomogram model was established based on the multiple logistic regression results, and the calibration curve showed that the prediction curve basically fitted the standard curve; the receiver operating characteristic curve showed that the area under the curve of the nomogram model for the prediction of suboptimal knee function in the early postoperative period after TKA was 0.894 [95% confidence interval (0.825, 0.963)]. Conclusions There is a significant improvement in knee function in patients after TKA, and the improvement of knee function in the early postoperative period after TKA is influenced by preoperative body mass index, etiology, and preoperative joint mobility, etc. The nomogram model established accordingly can be used to predict the improvement of knee function in the early postoperative period after TKA with a high degree of differentiation and accuracy.

    ObjectiveTo analyze the status and influencing factors of awareness of diabetic retinopathy (DR) knowledge in diabetics in Funing County, Jiangsu Province. MethodsThis is a cross-sectional study. In 2021, a total of 2 125 residents with diabetes in Funing County, Jiangsu Province were recruited using cluster random sampling methods. General examinations were performed and ophthalmological evaluation were conducted including visual acuity in daily life, slit lamp microscope with preset lens, digital non-mydriatic fundus photography. Clinical assessment and classification of DR were according to the international standard clinical classifications of diabetic retinopathy in 2019. DR was classified into no obvious DR, mild non-proliferative diabetic retinopathy (NPDR), moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR). Field questionnaire surveys were conducted to show the awareness rate of DR knowledge. Then Chi-square test and Logistic regression analysis were used to investigate influencing factors. ResultsAmong 2 125 subjects, 762 (35.86%, 762/2 125) residents were male and 1 363 (64.14%, 1 363/2 125) residents were female. A total of 444 (20.89%, 444/2 125) subjects were diagnosed as DR. Among which, 438 (20.61%, 438/2 125) subjects were NPDR, 6 (0.28%, 6/2 125) subjects were PDR. A total of 419 (19.72%, 419/2 125) subjects were diagnosed as cataract. The topic awareness rates were all below 45.00%. The overall population awareness rate was 19.45% (4 959/25 500). Awareness rate was correlated with age, visual acuity in daily life, education level, family history of diabetes, diabetic retinopathy grades and the type of treatment for diabetes (P<0.001). Logistic regression analysis showed that the knowledge rate of prevention and treatment of DR Decreased significantly in patients aged 60-79 compared with those aged under 50 (P<0.05). Compared with those with visual acuity<0.1 in daily life, the knowledge rate of DR prevention and treatment in those with visual acuity≥0.1 was significantly decreased (P<0.05). While primary school to college education, with family history of diabetes, with DR, oral hypoglycemic agents and/or insulin treatment were associated with higher awareness rate (P<0.05). ConclusionsThe DR knowledge level is low among diabetics in Funing County, Jiangsu Province in 2021. Age, visual acuity in daily life, education level, family history of diabetes, with DR and receiving drug treatments are main influencing factors for diabetic’s awareness.

  • CORRELATIVE FACTOR ANALYSIS OF COMPLICATIONS RESULTING FROM CEMENT LEAKAGE AFTER PERCUTANEOUS KYPHOPLASTY IN TREATMENT OF OSTEOPOROTIC VERTEBRAL BODY COMPRESSIONFRACTURES

    Objective To explore the correlative factors affecting the compl ications resulting from cement leakage after percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral body compression fractures (OVCF). Methods From February 2005 to October 2008, 71 patients with OVCF were treated by PKP and were retrospectively analyzed. There were 16 males and 55 females, and the average age was 71.5 years (range, 52-91 years). The average duration of disease was 5.7 months (range, 1-11 months). A total of 171 vertebra were involved in fracture including 19 cases of single vertebral fractures, 21 cases of double vertebral fractures, 20 cases of three vertebral fractures, and 11 cases of more than three vertebral fractures. All the treated vertebra were divided into acute (86 vertebra) or subacute (85 vertebra) state based on changes in MRI signal intensity. There was no radiculopathy or myelopathy. The average injected cement volumewas 4.6 mL (range, 1.5-6.5 mL). The treatment efficacy was assessed by observing the change in anterior and middle vertebral column height, Cobb angle, visual analogue scale (VAS) and Oswestry functional score at preoperation, 3 days after operation and last follow-up. The patients were divided into cement leakage group and no cement leakage group. All the compl ications were recorded, and then the correlative factors affecting the compl ications were analyzed. Results All the cases had rapid and significant improvement in back pain following PKP. All patients were followed up for 14 months (range, 7-18 months). There was no cement extravasation resulting in radiculopathy or myelopathy. Four patients (5.63%) had lung-related compl ications. During the follow-up, 9 recurrence vertebral fractures were observed in 6 patients (8.45%). The anterior and middle vertebral column height, Cobb angle, VAS and Oswestry score were significantly improved when compared with preoperation (P lt; 0.05). Cement leakage occurred in 17 (9.94%) vertebral bodies; of 17 cases, the cement leaked into the paravertebral space in 7 cases, intervertebral space in 6 cases, channel of needl ing insertion in 3 cases, and spinal canal in 1 case. Univariate analysis showed statistically significant differences (P lt; 0.05) in preoperative anterior and middle vertebral column height, injected cement volume and vertebral body wall incompetence between the cement leakage group and no cement leakage group. There were no significant differences (P gt; 0.05) in preoperative Cobb angle, freshness of vertebral fracture, location of operative vertebrae and operative approach between the two groups. Multiple logistic regression analysis showed that the injected cement volume [odds ratio (OR)=3.105, 95% confidence interval (CI)=1.674-5.759, P lt; 0.01] and vertebral body wall incompetence (OR=11.960, 95%CI=3.512-40.729, P lt; 0.01) were the predominant variable associated with the compl ications resulted fromcement leakage. Conclusion The injected cement volume and vertebral body wall incompetence were the factors affecting the compl ications. The improvement of surgical technique is the capital factor that may reduce the compl ications in the PKP.
