ObjectiveTo analyze the short- and long-term therapeutic effects of heart transplantation in children. MethodsA retrospective study was conducted on recipients and donors who underwent heart transplantation at the 7th People’s Hospital of Zhengzhou from May 2018 to August 2023, analyzing their clinical characteristics, surgical data, postoperative complications, and survival rates. ResultsA total of 22 children underwent heart transplantation, including 14 males and 8 females, with a median age of 13.5 (10.0, 15.0) years and a median weight of 41.9 (30.5, 55.4) kg. The primary diseases included: dilated cardiomyopathy in 16 patients, hypertrophic cardiomyopathy in 1 patient, myocardial dysplasia in 3 patients, right ventricular dysplasia in 1 patient, and congenital heart disease with abnormal coronary artery origin in 1 patient. The median age of the donors was 21.0 (13.0, 29.0) years, and the median weight was 50.5 (47.3, 75.0) kg. The blood types of the donors and recipients were the same, with type A in 10 patients, type B in 5 patients, type O in 5 patients, and type AB in 2 patients. Before transplantation, all children had a New York Heart Association cardiac function grade Ⅳ, with 1 patient assisted by intra-aortic balloon pump (IABP), 3 patients assisted by extracorporeal membrane oxygenation (ECMO), 2 patients assisted by continuous renal replacement therapy (CRRT), and 2 patients on mechanical ventilation. Nine patients met the criteria for emergency child status allocation, and the panel reactive antibody level in the patients was<10%. The median cold ischemic time of the donor heart was 355.0 (262.0, 395.5) min, the median aortic cross-clamping time was 45.0 (38.3, 51.3) min, the median mechanical ventilation time was 22.5 (16.8, 52.5) h, the median postoperative hospital stay was 29.5 (20.0, 43.0) d, and the median intensive care unit stay was 6.0 (5.0, 8.3) d. After surgery, 4 patients were assisted by ECMO, 2 patients by CRRT, and 7 patients developed complications, including lung fungal infection in 6 patients, liver and kidney dysfunction in 1 patient, local wound non-union and mediastinal infection in 1 patient, and multiple organ failure in 1 patient. Kaplan-Meier curve analysis showed that the survival rates of children after surgery were 91.3% at 1 year and 3 years; the survival rates of adult heart transplant recipients at our center were 86.7% and 73.8% at 1 year and 3 years, respectively, indicating that the survival rate of children with heart transplantation was higher than that of adult patients. ConclusionHeart transplantation is an effective treatment for end-stage heart failure in children, and the short- and long-term survival rates of children with heart transplantation are superior to those of adults. There are still many difficulties to be solved in pediatric heart transplantation, requiring joint efforts from society and the medical community.
Abstract: Objective [WTBZ]To evaluate the longterm effects of preoperative glucocorticoid treatment on postoperative complications and survival rates for patients receiving cardiac surgery. Methods [WTBZ] We selected 57 patients including 22 males and 35 females at an average age of 52.3±11.2 years in the First Hospital of China Medical University who took steroids for a long time because of various combined diseases from September 2002 to August 2009 in the trial group, and we chose another 171 patients including 62 males and 109 females at an average age of 53.6±9.2 years who were hospitalized at the same time and had comparative basic features in the control group. There was no statistical difference between the two groups in age, gender, and organ function. Different kinds of surgeries including coronary artery bypass grafting, heart valvuloplasty or valve replacement, coronary artery bypass grafting combined with heart valve replacement, and congenital heart disease surgery were performed on the patients. The proportion of surgeries carried out was similar in the two groups. Postoperative complications were compared between the two groups, and survival rates at the end of 6 months and one year followup were observed. Results [WTBZ]There was no statistical difference between the two groups in complications with respect to cardiopulmonary bypass (CPB) time (t=1.27, Pgt;0.05), reoperation for excessive postoperative bleeding (χ2=0.03, P=0.87), sternal and mediastinal infection (χ2=0.04, P=0.84), stroke (χ2=0.07, P=0.79), and gastrointestinal tract complications (χ2=2.89, P=0.09). The incidence of ventricular arrhythmia and requirement for intraaortic balloon pump in the trial group was higher, but no statistical difference was detected (χ2=2.24, P=0.13; χ2=2.20, P=0.14, respectively). Patients in the trial group were more likely to require prolonged ventilation (t=2.32, Plt;0.05), had higher rate of atrial fibrillation (χ2=4.09, P=0.04), and higher inhospital mortality (χ2=5.35, P=0.02). The sixmonth and oneyear survival rates were 0.79±0.10 and 0.73±0.12, respectively for the trial group, 0.94±0.09 and 0.86±0.10, respectively for the control group. Conclusion Longterm steroid treatment leads to higher atrial fibrillation incidence, longer ventilation time and increases the mortality rate following cardiac surgery.
Objective To observe the efficacy of photodynamic therapy (PDT) for choroidal neovascularization (CNV) secondary to pathological myopia (PM).Methods Sixty-six patients (73 eyes) with CNV secondary to PM who had undergone PDT were enrolled in this study. PDT was performed according to the standard treatment. The patients received the examinations of best corrected visual acuity (BCVA), ophthalmoscopy, fundus fluorescein angiography (FFA) and/or indocyanine green angiography (ICGA), and optical coherence tomography (OCT) before and after the treatment.Vision results were converted into logMAR records and compared before and after the treatment. The complete records of FFA were found in 52 eyes. FFA findings, treatment effects, were judged as well, moderate or poor according to the CNV leakage or bleeding, and CNV expanding or shrinking. The complete records of OCT were found in 11 eyes. CNV regional edema and foveal thickness were analyzed based on OCT examination.Results The mean logMAR BCVA after PDT treatment was 0.74plusmn;0.51 with no significant difference compared with before treatment (t=1.11, P=0.27). There were 18 eyes (24.7%) with improved vision, 43 eyes (58.9%) with stable vision, and 12 eyes (16.4%) with decreased vision. In 52 eyes with FFA findings, 39 eyes (75.0%) with well effect, 9 eyes (17.1%) with moderate effect, and 4 eyes (7.7%) with poor effect. OCT showed that after treatment the CNV regional edema subsided in most of eyes, and there were 7 (63.64%) with decreased foveal thickness, 2 (18.18%) with stable thickness, and 2 (18.18%) with increased thickness. Conclusions PDT is an effective treatment for CNV secondary to PM. It may improve or stabilize the visual acuity.
ObjectiveTo analyze the subfoveal choroidal thickness in retinitis pigmentosa (RP) patients and to evaluate the correlation between the subfoveal choroidal thickness (SCT) and visual function. MethodsTotally 42 RP patients (84 eyes) and 49 age and diopter-matched normal controls (98 eyes) were enrolled in this study. All the patients were taken the enhanced depth imaging technique of optical coherence tomography (EDI-OCT) examination for the measurement of the SCT. The covariate analysis was used to analyze the interaction effect between age and group. Then the SCT was amended. The RP patients were examined by 30°visual field test (T32 or LVC program) and electroretinogram (ERG) test. 32 eyes examined by T32 program, 52 eyes examined by LVC program. The waveform of ERG, mean sensitivity (MS) and mean defect (MD) were recorded. The relationship of SCT, MS and MD were analyzed by Pearson correlation analysis. ResultsThe SCT of RP patients and controls were (223.12±69.59), (288.29±52.36) μm. The covariate analysis of covariance with different age group interaction was not statistically significant (F=1.619, P=0.205), as amended SCT of RP patients and controls were (217.34±6.60), (293.20±6.00) μm, respectively. The SCT was decreased in RP patients (t=7.042, P < 0.001). Among 84 eyes, bright cone response weaken in 35 eyes, scotopic rod response weaken in 31 eyes. The difference of SCT in different ERG waveform was not significant (t=-0.976, -1.584; P=0.332, 0.117). The MS and MD of 32 eyes using T32 program were (9.05±6.42), (18.84±6.30) dB, the SCT was (209.83±71.48) μm; the MS and SCT of 52 eyes using LVC program were (7.14±5.03) dB and (228.32±66.32) μm. The SCT was related to MS (r=0.494, P=0.003) and MD (r=-0.448, P=0.009) in eyes using T32 program. There was no correlation between SCT and MD in eyes using LVC program (r=-0.232, P=0.095). ConclusionsThe SCT of RP patients is thinner than that of normal controls. The SCT of RP patients is related to MS and MD of T32 program, but not correlated to ERG waveform and MS of LVC program.
Objective To evaluate the therapeutic effect of vitreo-retinal surgery on oclular siderosis. Methods The clinical data of 22 patinets (22 eyes) with ocular siderosis due to the magnetic foreign body at intraocular postsegment were retrospectively analyzed. The patients aged from 6 to 54 years (average 40 years), including 21 males and 1 femal. The duration of the magnetic foreign body remained in the eye lasted for 1 month to 20 years. The preoperative best corrected visual acuity (BCVA) was ＜0.01 in 15 eyes, 0.01-0.15 in 5 eyes and 0.1-0.2 in 2 eyes. There was Intra-vitreous foreign body in 18 eyes and ocular wall embedded foreign body in 4 eyes; intraocular foreign body (IOFB) combined with cataract in 18 eyes; combined with retinal detachment in 3 eyes; scleral buckling combined with silicon oil filled in 12 eyes and C3F8 filled in 7 eyes. Cataract extraction was performed in 12 eyes, and 2 eyes underwent filtrating surgery. Results The IOFB was successfully removed by one-off surgery in 22 eyes. BCVA increased in 20 eyes (90.9％) and kept unchanged in 2 eyes (9.1%), including＜0.1 in 7 eyes, 0.1-0.4 in 8 eyes, and 0.5-1.0 in 7 eyes. Operative complications involved retinal holes with retinal detachment in 2 eyes and vitreous haemorrhage secondary to enlarge sclera incision in 2 eyes. Postoperative complications included secondary cataract in 4 eyes, retinal detachment due to silicon oil removal 3 months after submacular removal of foreign body in 1 eye, and retinal detachment 7 days after C3F8 filling in 1 eye; the latter two eyes had reattached retina after another silicon oil filling. At the end of the follow-up period, retina reattached in 22 eyes. Conclusion Advanced modern vireoretinal operation is effective on oclular siderosis, which can avoid the release of Fe+ and improve the patientsprime; visual function.
Objective To compare effectiveness between laparoscopic Heller myotomy and peroral endoscopic myotomy (POEM) in treatment of achalasia of cardia (AC) in order to provide a basis for clinical choose. Method The literatures about the treatment of AC by laparoscopic Heller myotomy or POEM were retrieved from CNKI, Embase, PubMed databases, etc., and then the contents about curative effect and complications were summarized. Results The treatment models of AC included surgical treatment such as laparoscopic Heller myotomy and endoscopy such as POEM, but there was still lack of comparing data in these two treatment models, its selection remained controversial. There was a better short-term curative effect and slighter complications for POEM as compared with the laparoscopic Heller myotomy from the trend of published literatures. However, it’s long-term effects for these two treatment models were not clarified. Conclusions Both laparoscopic Heller myotomy and POEM are medicable for AC. POEM as a new treatment of AC shows some advantages of minimal invasion and exact efficacy, but it needs to be followed-up for a long-term. Treatment model for AC is chosen on basis of typing under endoscope, physical fitness, anatomy of easophagus, previous history, tolerance of surgery and other factors.
Objective To observe ocular manifestations of acquired immunodeficiency syndrome（AIDS）.Methods Fourtytwo AIDS patients（66 eyes）with ocular complaints received examinations of visual acuity, slit-lamp microscope, ophthalmoscope and fundus fluorescence angiography (FFA). The results were retrospectively analyzed. Results There are five types of ocular findings, including cytomegalovirus (CMV) retinitis (37 eyes, 56.0%), retinal microvasculopathy of human immunodeficiency virus (21 eyes, 32.0%), optic nerve diseases (three eyes, 4.5%), retinal neuroepithelial layer detachment (two eyes, 3.0%) and uveitis (three eyes, 4.5%).Conclusions The common ocular manifestations showed progressive necrotic retinitis, retinal hemorrhage and retinal vasculitis and attenuated，cotton-wool spots in AIDS patients.
Objective To observe the therapeutic effects of photodynamic therapy（PDT）on choroidal neovascularization（CNV）with or without cystoid macular edema（CME）in patients with wet agerelated macular degeneration（AMD）. Methods The clinical data of 54 patients (54 eyes) with wet AMD who had undergone the standard PDT，including 16 patients（21 eyes）with CME and 28 patients（33 eyes）without CME were retrospectively analyzed. The visual acuity and BFT of patients were examined by early treatment diabetic retinopathy study (ETDRS) and optical coherence tomography（OCT）before and per three months after PDT. The follow up was 3-18 months with the mean of 8.3 months.Results At the last time of follow up, in CME group，ETDRS letter score was（29.429plusmn;17.907）and the BFT was （316.429plusmn;77.161）mu;m，compared with that before the treatment, the difference were statistically significant (t=-0.389，2.246；P＝0.701，0.019). In nonCME group, ETDRS letter score was (48.121plusmn;17.911) and the BFT was (244.667plusmn;37.619) mu;m, compared with that before the treatment, the difference were statistically significant (t=-3.424，6.880；P＝0.002，0.000). There were statistical significance for the change of ETDRS letter score and BFT between the two groups (t=-2.194，2.212；P＝0.033，0.031）). Conclusions Therapeutic effect of PDT on CNV with CME was better than without CME in patients with wet AMD.
ObjectiveTo compare the impact of early enteral nutrition (EN) and parenteral nutrition (PN) on the postoperative efficacy of esophageal cancer through meta-analysis of relevant randomized controlled trial (RCT).MethodsPubMed, Medline, EMbase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP, China Biology Medicine disc (CBMdisc) were searched by computer from inception to April 2018 to identify potential RCT which assessed clinical efficacy between EN and PN for postoperative patients with esophageal cancer. According to the inclusion and exclusion criteria, two researchers independently screened and evaluated literature. Meta-analysis was performed by RevMan 5.3 software.ResultsA total of 30 RCT studies were selected, including 3 969 patients. Meta-analysis results showed that: there was a significant difference between EN and PN in postoperative anastomotic fistulas (I2=0%, OR=0.67, 95%CI 0.45-0.99, P=0.04), postoperative pulmonary infections (I2=0%, OR=0.42, 95%CI 0.32-0.55, P<0.000 1), postoperative albumin levels (I2=38%, MD=0.78, 95%CI 0.51-1.06, P<0.000 01),time of first anal exhaust after operation (I2=0%, MD=–23.16, 95%CI –25.16-21.16, P<0.000 01) and postoperative incision infection (I2=0%, RR=0.36, 95%CI 0.21-0.64, P=0.000 5).ConclusionCompared with PN, early EN can significantly reduce the incidence of major postoperative complications and shorten the time of first anal exhaust after surgery. In addition, EN is superior to PN in improving nutritional status, increasing weight and reducing costs and side effects.
Objective To observe the clinical characteristics and therapeutic effects of carotid artery stenosisrelated ocular ischemic appearance(OIA).Methods The clinical data of 210 patients of carotid artery stenosis (81 of them with OIA) were retrospectively reviewed. They were diagnosed by color doppler image（CDI）or digital subtraction angiography (DSA),and had undergone medicine,carotid artery stenting (CAS)and carotid endarterectomy (CEA). Of 81 patients with OIA,49 patients (60.49%) with OIA only, 32 patients（39.51%）with ocular ischemic disease (OID).24/32 OID patients received ophthalmic treatment such as retinal laser photocoagulation and anti glaucoma therapy (drugs and cyclocryotherapy). Results The ocular manifestations of 81 OIA patients included transient amaurosis in 38 cases (47.14%),flash before the eye in 30 cases (36.67%), periorbital swelling and pain in 28 cases (34.57%), diplopia in 11 cases (13.58%) and vision loss in 9 cases (11.11%). The ocular manifestations of 32 OID patients included ischemic optic neuropathy in 9 cases (28.13%), ocular ischemic syndrome in 6 cases (18.75%), central or branch retinal artery occlusion in 6 cases (18.75%), retinal hemorrhage in 5 patients (15.62%)，extraocular muscle paralysis in 4 patients (12.50%) and neovascular glaucoma in 2 patients (6.25%). The higher the degree of carotid stenosis,the higher incidence of ocular ischemic disease,there was highly positive correlation between each other (R=0.837, P＜0.05).The total effective rate of carotid artery stenting and carotid endarterectomy was significantly higher than drug treatment alone (t=2.73, 3.14; P＜0.01). Conclusion The ocular manifestations of carotid stenosis related ocular ischemic appearance can be transient amaurosis, eyes flashing,eye redness,periorbital pain, diplopia and decreased visual acuity.The ocular manifestations of carotid stenosisrelated ocular ischemic disease can be ischemic optic neuropathy, ocular ischemic symptoms, central or branch retinal artery occlusion and neovascular Carotid artery stenting and carotid endarterectomy are more effective than drug treatment alone for those patients.
