Objective To analyze the relationship between Glasgow prognostic score （GPS）， liver metastasis， and prognosis of rectal caner. Methods Clinical data of 223 patients with rectal cancer who underwent operation in Chinese PLA General Hospital from Jun. 2005 to Dec. 2011 were retrospectively analyzed， and the relationship between preoperative GPS score， liver metastasis， and prognosis of rectal cancer were analyzed. Results Preoperative GPS score of patients with rectal cancer was related to invasion depth （P＜0.001）， vascular or lymphatic invasion （P＜0.001）， liver metastasis （P＜0.001）， TNM stage （P＜0.001）， levels of carcinoembryonic antigen （P=0.009）， levels of CA19-9（P＜0.001）， and levels of CA724 （P＜0.001）. Multivariate analysis results revealed that differentiation of tumor （poorly：OR=10.688）， vascular or lymphatic invasion （OR=4.918）， lymph node metastasis （OR=3.359）， and preoperative GPS score （score 2：OR=15.907） were related to liver metastasis；age （RR=2.121）， differentiation of tumor （poorly：RR=2.846）， invasion depth （RR=1.754）， TNM stage （stageⅡ：RR=7.447， stageⅢ：RR=9.030， stage Ⅳ：RR=13.325）， and preoperative GPS score （score 2：RR=2.471） were the independently prognostic factors of rectal cancer. The preo- perative GPS score were related with both liver metastasis and prognosis of rectal cancer. Conclusion Preoperative GPS score is associated with liver metastasis of rectal cancer， and it is considered to be a useful predictor of postoperative prognosis in rectal cancer.
To investigate the value of plasma placental growth factor (PlGF) in percutaneous coronary angioplasty and stent implantation. Methods From May 2006 to March 2007, 61 patients (53 males and 8 females, mean age61 years) and 28 normal controls were included. All patients present with acute chest pain and underwent coronary angiography, the lesion severity of coronary arteries was assessed by Gensini coronary scoring system. Of them, 26 patients having serious coronary lesion underwent (percutaneous transluminal coronary angioplasty, PTCA) and stent implantation. Cardiovascular events were recorded after 30 days. Plasma PlGF was determined by ELISA. Results According to the angiography, the patients could be divided into CAD group (n=45) and Non- CAD group (n=16). Plasma PlGF level in CAD group was significantly higher than that in Non-CAD group and control group [(10.70 ± 0.49) ng/L vs (4.53 ± 0.64) ng/L vs (3.64 ± 0.36) ng/L, P lt; 0.001)], and there was no significant difference between the non-CAD group and control group (P gt; 0.05). A significant positive correlation was found between Gensini coronary score and plasma PlGF level (r=0.918, P lt; 0.01). Moreover, patients with cardiovascular events had a higher PlGF level than those without cardiovascular events after PTCA and stent implantation [(13.98 ± 3.39) ng/L vs (7.25 ± 2.96) ng/L, P lt; 0.01)]. Conclusion PlGF level has diagnostic value in patients with acute chest pain. The measurement of plasma PlGF might be helpful for early diagnosis of coronary artery disease. Patients with higher plasma PlGF level may have more severe coronary lesion. PlGF may be one of predictors for cardiovascular events after PCI.
Objective To investigate the impact of peripheral artery disease (PAD) on the short-term prognosis after coronary artery bypass grafting (CABG) in patients of different age groups. MethodsRetrospective inclusion of patients who underwent CABG at Tongji Medical College Affiliated Union Hospital of Huazhong University of Science and Technology from 2016 to 2020. Divided into four groups by age (<50 years, 50-60 years, 60-70 years, >70 years). Propensity score matching (PSM) was used to balance the baseline characteristics of PAD and non PAD patients across different age groups. The primary endpoint of the study was all-cause mortality, and the secondary endpoint was major adverse cardiovascular and cerebrovascular events (MACCE) during the perioperative period. ResultsTotally, 1 516 patients were enrolled, including the GroupⅠ (<50 years, n=167), Group Ⅱ (50-60 years, n=477), Group Ⅲ (60-70 years, n=688), and Group Ⅳ (>70 years, n=184). After PSM treatment, a total of 375 pairs of patients (75.2% male) were successfully matched. Only in the age group of 60-70 years, the in-hospital mortality rate (7.73% vs. 1.45%, P＜0.01) and MACCE incidence rate (21.26% vs. 13.04%, P=0.02) of PAD patients were significantly higher than those of the non PAD group. Further multivariate analysis suggests that PAD is an independent risk factor for in-hospital mortality (OR=3.96, P＜0.01) and MACCE (OR=1.58, P=0.04) in this group, while there is no statistically significant difference in other age groups. Conclusion: PAD significantly increases the risk of recent mortality and MACCE in CABG patients aged 60-70 years, and perioperative management needs to be optimized for this population.
Objective To investigate the value of retention rate of indocyanine green at fifteen minutes (ICGR15) during hemihepatectomy for evaluation of residual liver reserve function in patients with primary liver carcinoma. Methods During hemihepatectomy, ICGR15 was tested in 44 patients after the hepatic artery and portal vein of resected side were ligated. Child-Pugh score, Child-Pugh classification, and MELD score before operation were tested. After operation, the liver function condition was estimated. Results The incidence of liver dysfunction was significantly lower in ICGR15lt;10% group (17.9%, 5/28) than that in 10%~15% group (75.0%, 12/16), Plt;0.05. There was no significant difference of Child-Pugh score among normal liver function group, mild insufficiency of liver function group, and severe insufficiency of liver function group （Pgt;0.05）. ICGR15 and MELD score in normal liver function group were statistical lower than those in mild insufficiency of liver function group and severe insufficiency of liver function group (Plt;0.05). ICGR15 was significantly lower in Child-Pugh A group than that in Child-Pugh B group (Plt;0.05). Conclusion Intraoperative residual liver ICGR15 may be more precisely compared with Child-Pugh score in evaluation liver reserve function for the patients with primary liver carcinoma and can help to guide liver resection.
Objective To evaluate the effects and the clinical significances of liquid resuscitation on blood gas analysis， acid-base balance， electrolytes， acute physiology and chronic health evaluationsⅡ（APACHEⅡ） score of patients with septic shock， and then to analyze the relations between serum chlorine （Cl－） level and APACHEⅡscore and the volume of liquid resuscitation. Methods According to the target of resuscitation （centre venous pressure 8-12mm Hg and mean arterial pressure≥65mm Hg）， 21 patients with septic shock received enough fluid for resuscitation during 24h . The results of blood gas analysis， acid-base balance， electrolytes， and APACHE Ⅱ score were compared between pre-resuscitation and 24h post-resuscitation by self-controlled prospective study. The relationships of the level of serum Cl－ and APACHEⅡ score with the volume of liquid used in resuscitation were analyzed . Results The mean resus-citation duration was （18.09±4.57） h， and the volume of liquid during 24 h resuscitation was 5 320-11 028mL with mean volume of （7 775±1 735） mL in 21 patients with septic shock. Serum sodium （Na＋， mmol/L） and Cl－（mmol/L）levels of post-resuscitation were significant higher than those of pre-resuscitation （Na＋：138.71±5.67 versus 135.62±7.23， P=0.024；Cl－：109.10±4.90 versus 101.67±8.59， P=0.000）. Compared with the levels of pre-resuscitation， the blood pH value， hematocrit （Hct，%）， anion gap （AG， mmol/L）， lactic acid （mmol/L）， and APACHE Ⅱscore significantly decreased （pH：7.31±0.05 versus 7.37±0.06， P=0.000；Hct：28.48±2.56 versus 32.76±9.19， P=0.049；AG：8.33±3.45 versus 14.17±8.83， P=0.004；lactic acid：1.66±0.89 versus 2.96±1.23， P=0.001；APACHEⅡ：10.90±3.73 versus 17.24±4.06， P=0.000） after 24h resuscitation. The correlation analysis showed that the level of serum Cl- was positively correlated with the volume of liquid used in resuscitation （r=0.717，P＜0.01）. However， there was no correlation between APACHEⅡscore and the volume of liquid used in resuscitation （P＞0.05）. Conclusions The target of liquid resuscitation in patients with septic shock should be cautiously determined， including control of the volume of crystal liquid for resuscitation， in order to avoid acid-base imbalance or hyperchloraemia. At the same time， the change in internal environment should be monitored. An optimistic fluid resuscitation to decrease APACHE Ⅱ score in patients with septic shock is unrelated to the volume of liquid resuscitation.
This study introduced the inverse probability weight and overlap weight by propensity score and how to test the balance and estimate the effect after weighting. Four R packages that can be used for propensity score weight analysis were introduced and compared.
Objective To investigate the status of frailty in patients with coronavirus disease 2019 (COVID-19), and to analyze the influence of COVID-19 disease on the prevalence of frailty. Methods This study was conducted using a cross-sectional survey method. COVID-19 patients admitted to a centralized isolation point in Guangzhou were selected for an questionnaire survey by “questionnaire star”, between November and December 2022. The questionnaire included the general information questionnaire, Tilburg Frailty Indicator (TFI), the COVID-19 symptom scale and Mental Resilience Scale (RS-11). Multi-model logistic regression analysis was used to explore the influence of COVID-19 on the occurrence of debilitation. Results A total of 667 questionnaires were distributed, of which 594 were valid, with an effective rate of 89.1%. There were 150 patients (25.3%) were frail, 444 patients (74.7%) were non-frail, and 51 patients (8.6%) were newly frail after infected COVID-19. The median TFI score before COVID-19 was 3 (2, 4) points, 16.7% (99/594) were in a weak state. The median TFI score after COVID-19 was 3 (2, 5) points, 25.3% (150/594) were in a weak state. There were statistically significant differences in TFI scores (Z=−6.596, P＜0.001) and the incidence of debilitation (χ2=351.648, P＜0.001) before and after COVID-19. The results of multivariate logistic regression analysis showed that after controlling disease factors, demographic factors and psychosocial factors, the score of the COVID-19 symptom score was always the influencing factor of COVID-19 patients. The overall change trend of COVID-19 symptom score was statistically significant (P<0.001). Conclusions The COVID-19 symptom score is an important risk factor or predictor of frailty in patients with COVID-19. As the level of COVID-19 symptom score increases, the risk of frailty in COVID-19 patients increases.
Objective To explore the evolving strategies and compare perioperative and long-term outcomes of tricuspid valve replacement (TVR) in recent 20 years in our hospital.MethodsBetween 1998 and 2018, the clinical data of 608 patients who underwent TVR at the Department of Cardiac Surgery, Guangdong Provincial People’s Hospital were retrospectively analyzed. There were 201 males and 407 females, with a median age of 47.0 (36.0, 57.0) years. Patients were divided into a biological tricuspid valve (BTV, n=427) group and a mechanical tricuspid valve (MTV, n=181) group. Propensity score matching was used to balance the baseline difference. Surgical strategy evolving, postoperative and long-term outcomes were analyzed between the two groups.ResultsSince 2008, the usage ratio of biological valves was significantly higher than that of mechanical valves. Seventy-nine (13.0%) patients died in hospital after TVR. Before propensity score matching, the postoperative mortality of the BTV group was higher than that of the MTV group (15.2% vs. 7.7%, P=0.012), and there was no statistical difference between the two groups after matching (10.4% vs. 7.2%, P=0.372). The duration of postoperative ventilator support in the BTV group was longer than that in the MTV group [22.0 (15.0, 37.0) h vs. 19.0 (11.0, 27.0) h, P=0.003], and the incidence of postoperative dialysis and re-thoracotomy exploring for bleeding was higher in the BTV group (8.9 % vs. 2.8%, 9.4% vs. 6.6%, respectively). However, there was no statistical difference in mortality after matching. The median follow-up time of discharged patients was 101.0 (65.0, 147.0) months, ranged from 1 to 265 months, and the follow-up rate was 82.2%. During the follow-up period, there were 101 deaths (19.1%) of whom 68 were from the BTV group and 33 from the MTV group. The survival rates at 1 year, 5 years, 10 years, 15 years and 20 years of all patients were 85.0% (95%CI 82.2-87.9), 78.9% (95%CI 75.7-82.4), 71.1% (95%CI 67.3-75.3), 59.7% (95%CI 54.2-65.6) and 51.7% (95%CI 43.3-60.7), and there was no statistical difference between the two groups after matching (P=0.46). The median time of tricuspid valve failure was 84.0 (54.0-111.0) months.ConclusionTVR is associated with high perioperative risks. There is no statistical difference in early mortality and long-term survival between biological and mechanical valve, while patients with mechanical valve has higher risk of re-operation for valve failure. Therefore, the type of prosthetic valve can be selected according to the patients' age, physical condition and the doctors’ experience.
ObjectiveTo compare the effectiveness of radiofrequency ablation (RFA) combined with transilluminated powered phlebectomy (TIPP) vs. high ligation and stripping (HLS) combined with TIPP in patients with varicose veins of lower limbs.MethodsA retrospective analysis was made on the clinical data of 190 patients (206 limbs) of varicose veins of lower limbs who underwent surgical treatment in our hospital from December 2017 to July 2018, of them 88 patients (96 limbs) in RFA combined with TIPP group and other 102 patients (110 limbs) in HLS combined with TIPP group. The treatment effectiveness and quality of life was assessed with venous clinical severity score (VCSS) and chronic venous insufficiency questionnaire (CIVIQ-14) in three months and one year after surgery. Doppler ultrasound was used to evaluate the closure of great saphenous vein.ResultsBaseline characteristics were similar between the two groups (P>0.05). The RFA combined with TIPP group was better than the HLS combined with TIPP group in operation time, intraoperative bleeding, hospital stay time, postoperative bed time, resumption time of activities, as well as incidences of skin induration and limb numb (P<0.05). Occlusion rates of great saphenous vein in 3 months was 93.8% (90/96) in the RFA combined with TIPP group and 97.3% (107/110) in the HLS combined with TIPP group, and in one year was 91.7% (88/96) and 97.3% (107/110) respectively, there was no significant difference between the two groups at the same time point (P>0.05). The VCSS scores and CIVIQ-14 scores also improved significantly in two groups in 3 months and 1 year follow up (P<0.05), but there was no significant differences between the two groups at the same time point (P>0.05).ConclusionsRFA combined with TIPP is an effective method for the treatment of varicose veins of lower limbs. Compared with HLS, RFA has the same good effectiveness and quality of life, but it has the advantages of short operation time, rapid postoperative recovery, and less postoperative complications.
ObjectiveTo investigate the safety, feasibility and advantages of subxiphoid uni-portal thoracoscopic thymectomy.MethodsClinical data of 65 patients undergoing subxiphoid uni-portal thoracoscopic thymectomy in our hospital from September 2018 to March 2019 were retrospectively analyzed. They were treated as a subxiphoid surgery group, including 36 males and 29 females, aged 49.5 (29-71) years. The incision with the length of about 3 cm was located approximately 1 cm under the xiphoid process. From January 2016 to December 2017, 65 patients received intercostal uni-portal thoracoscopic thymectomy, who were treated as a control group, including 38 males and 27 females, aged 48.9 (33-67) years. All patients who were clinically diagnosed with thymic tumor before surgery were treated with total thymectomy. After surgery, expectoration and analgesia were used.ResultsThere was no statistically significant difference in general clinical data, lesion size, intraoperative blood loss, postoperative catheterization time, postoperative hospital stay and postoperative pathology between the two groups. All operations were successfully completed, and the patients in both groups recovered uneventfully after surgery. Visual analogue scale scores on the 1st, 3rd, 7th and 30th day after surgery in the subxiphoid surgery group were lower than those in the control group.ConclusionThe subxiphoid uni-portal thoracoscopic approach can achieve total thymectomy with less trauma and faster postoperative recovery.
