Objective:To compare the efficacy and safety of Castor single-branch stent and in vitro fenestration stent in treating thoracic aortic diseases with insufficient landing zone.Methods:The clinical data of patients with thoracic aortic diseases treated with Castor single-branch stent or in vitro fenestrated stent between December 2017 and June 2021 in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. A total of 184 patients were included, 99 patients were treated with Castor branch stent, and 85 patients with in vitro fenestration stent. All patients′ general clinical data, surgical data, perioperative and follow-up clinical and imaging data, and postoperative complications were collected. The χ2 test was used to compare the incidence of complications between the two groups, and the Kaplan-Meier method was used to plot the survival rate without adverse events between the two groups. Results:Stent placement was successful in all patients, and the success rate of the technique was 100%. Other branches were reconstructed in 2 patients in the Castor group and double fenestrated stent were reconstructed in 12 patients in the fenestrated group. The mean operation time of the Castor group was significantly shorter than that of the fenestrated group, the number of patients who received local anesthesia was significantly lower than that of the fenestrated group, and the endoleak rate during follow-up was significantly lower than that of the fenestrated group ( P<0.05). There was no significant difference in the postoperative hospital stay, the incidence rate of perioperative complications, mortality, the incidence rate of neurological complications, new dissection or aneurysm rate, branch stent stenosis rate, second surgical intervention rate, and false lumen thrombosis between the two groups ( P>0.05). The adverse event-free survival rate of the Castor group was slightly higher than that of the fenestrated group, but its difference was not statistically significant ( P>0.05). Conclusion:Castor branch stent and in vitro fenestration stent have good short-term and mid-term efficacy in the treatment of aortic diseases with insufficient landing zone, which are safe and effective options for reconstruction of LSA and other branch arteries.

AIM: To evaluate the safety and efficacy of ultrasonic cycloplasty(UCP)combined with anti-vascular endothelial growth factor(VEGF)+ panretinal photocoagulation(PRP)in the treatment of advanced neovascular glaucoma(NVG).METHODS: Retrospective study. A total of 45 patients(45 eyes)with advanced NVG who received surgery in our hospital from August 2020 to September 2022 were collected and divided into UCP+ anti-VEGF +PRP group(16 patients, 16 eyes), transscleral cyclophotocoagulation(TCP)+anti-VEGF+PRP group(20 patients, 20 eyes), UCP alone group(9 patients, 9 eyes). The intraocular pressure, pain scores, postoperative medication, effective rate, total success rate and the incidence of complications of the patients in the three groups were compared before surgery and at 1 d, 1 wk, 1 and 3 mo after surgery.RESULTS: There was no significant difference in preoperative intraocular pressure, pain scores and preoperative medication of patients in the three groups(all P>0.05). While there were statistical significance in the intraocular pressure and pain scores at 1 d, 1 wk, 1 and 3 mo after surgery(all P<0.01). The intraocular pressure of the UCP alone group(31.78±10.23 mmHg)was found to be higher than that of both the UCP+ anti-VEGF +PRP group(19.44±8.23 mmHg)and the TCP+ anti-VEGF +PRP group(20.80±10.27 mmHg)at 1 mo postoperatively(all P<0.017). The pain score of the TCP+ anti-VEGF +PRP group at 1 d and 1 wk postoperatively was higher than both the UCP+ anti-VEGF +PRP group and the UCP alone group(all P<0.017). The effective rates of UCP+ anti-VEGF +PRP group, TCP+ anti-VEGF +PRP group and UCP alone group were 81%(13/16), 75%(15/20)and 67%(6/9), respectively,(P=0.675), and the success rates were 69%(11/16), 50%(10/20), and 0(0/9), respectively(P=0.003). There was no significant difference in complications of patients in the three groups(P>0.05).CONCLUSION: UCP combined with anti-VEGF +PRP and TCP combined with anti-VEGF +PRP showed comparable efficacy in reducing intraocular pressure in advanced NVG. UCP combined with anti-VEGF+PRP was more effective in relieving pain and with no serious complications in advanced NVG. UCP alone can effectively control intraocular pressure and alleviate the pain of patients in the early postoperative period, but long-term control still requires anti-VEGF+PRP.

Objective To analyze the short- and long-term therapeutic effects of heart transplantation in children. Methods A 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. Results A 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. Conclusion Heart 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.

OBJECTIVE： To investigate the improvement effects of external application of water extract from Picrasma quassioides on allergic contact dermatitis （ACD） model mice， and to provide reference for its further development and utilization. METHODS： A total of 48 mice were randomly divided into blank control group （normal saline）， model group （normal saline）， hydrocortisone group （positive control， about 0.15 g/ear） and water extract from P. quassioides low-dose， medium-dose and high-dose groups （0.15， 0.3， 0.6 g/ear， calculated by extract）， with 8 mice in each group. The mice were given medicine on ear at 8 a.m. and 4 p.m. for 7 d continuously. Except for blank control group， other groups were given acetone-olive oil solution containing 0.5％ 2，4-dinitrofluorobenzene （DNFB） on the abdomen of mice to induce ACD model. After 7 d medication， modeling group was given acetone-olive oil of 0.25％ DNFB on left ear to induce dermatitis. 24 h later， the pathological changes of left ear tissue were observed by naked eye and skin lesion was scored. The thickness difference and weight difference of left and right ears in mice were measured. The serum contents of IL-6 and IgE were determined. The pathomorphology changes of ear tissue were observed by microscope after HE staining. RESULTS： Compared with blank control group， the skin lesion score of left ear was increased significantly in model group （P＜0.01）； the thickness difference and weight difference of left and right ears， serum contents of IgE and IL-6 were increased significantly （P＜0.01）. Pathological changes were observed in left tissue of mice by microscope， such as lymphocytic infiltration， intercellular edema， erythrocyte exudation. Compared with model group， skin lesion score of left ear in mice was decreased significantly in hydrocortisone group and water extract from P. quassioides high-dose group （P＜0.05 or P＜0.01）； the thickness difference and weight difference of left and right ears in mice were decreased significantly in all administration groups （P＜0.01）. The serum contents of IgE and IL-6 in mice were decreased significantly in hydrocortisone group， water extract from P. quassioides medium-dose and high-dose groups （P＜0.01）； the inflammatory lesions of left ear in mice were alleviated to varying degrees in different administration groups. CONCLUSIONS： External application of water extract from P. quassioides has a good improvement effect on ACD model mice.

PURPOSE: This study was aimed to investigate the effect of pseudolaric acid B (PAB) on proliferation, invasion and epithelial-to-mesenchymal transition (EMT) in pancreatic cancer cells and to explore the possible mechanism. MATERIALS AND METHODS: The pancreatic cancer cell line SW1990 was cultured and treated with PAB dose- and time-dependent manners. Cell proliferation and invasion ability were measured by MTT assay and Matrigel/Transwell test, respectively. Semi-quantitative real-time polymerase chain reaction and Western blotting were conducted to detect the expression of EMT markers and the key molecules. Finally, nude mice subcutaneous transplantation tumor model was used to confirm the therapy efficacy of PAB. RESULTS: PAB could inhibit SW1990 cell proliferation and invasion in time- and dose-dependent manners. Vimentin, fibronectin, N-cadherin, Snail, Slug, YAP, TEAD1, and Survivin were down-regulated (p < 0.01), while E-cadherin, caspase-9, MST1, and pYAP were up-regulated (p < 0.05). Combined PAB and gemcitabine treatment markedly restricted the tumor growth compared with gencitabin or PAB alone groups. CONCLUSION: PAB could inhibit the proliferation and invasion ability of pancreatic cancer cells through activating Hippo-YAP pathway and inhibiting the process of EMT.
