BACKGROUND: The expression of main histocompatibility antigen in cornea of rats is similar to that of human. It is verified in early experiments that penetrating corneal transplantation in rats is more repetition and reliability, and the operation difficulty is lower than that in mice.OBJECTIVE: To establish rat model of penetrating corneal transplantation and analyze the reasons of complications during model preparation and the corresponding managements and probe into the method for improving the success rate of rat model of corneal transplantation.DESIGN: Randomized controlled experiment was designed.SETTING: Department of Ophthalmology , Union Hospital, Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: The experiment was performed in Department of Ophthalmology in Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from March to May 2004. Seventysix outbred female Wistar rats of two months old were employed and randomized into experimental group and control group with 38 rats in each,without eye disease, of clean grade, body mass varied from 180 to 200 g and their right eyes were taken as acceptors. Thirty-eight SD female rats were employed and their both eyes were taken as donors. All of the animals were provided from Experimental Animal Center of Tongji Medical College of Huazhong University of Science and Technology.METHODS: Central penetrating corneal transplantation in situ was adopted and the model was established on the right eye of Wistar rat. Ten minutes before operation, tropicamide eye drops was administrated twice to amplify adequately the pupil of the right eye up to 4.0 mm. According to body mass, general anesthesia was done with abdominal injection of 3.0 mL/kg chloral hydrateand dicaine eye drops was applied twice 5 minutes before the operation with 0.1 volume fraction. Routine sterilization was done on the head of rat, the eyes kept in horizontal level and respiration kept smooth. The clip in dental-ophthalmology department was used to fix the posterior of the operated eye and make it to be semiluxated. The ring driller 3.5 mm in diameter was used to collect corneas of both eyes in SD rat as the implant tissue and place in culture dish with endothelial part upward, covered with methyl cellulose of 20 g/L mass weight concentration. The ring driller, 3.0 mm in diameter was used to collect the cornea of the right eye in Wistar rat to be the graft foreman, and the implant tissue was sutured into the graft foreman on the right eye of Wistar rat with 10-0nylon thread intermittently. Eight stitches were done in corneal transplantation in the experimental group and 6 stitches in the control group. After operation, ofloxacin eye drops was administrated and the operated eye was covered with plaster. Corneal rejection was observed and the evaluation was done in 3 items, named, turbidity, edema and neogenetic vessel. The total score of 3 items was taken as the rejection index on the day. Rejection was determined if the rejection index on the day ≥5 or corneal turbidity reached the 3nd grade. x2 and Fisher definite probability methods were used for statistical examination.plant tissue and corneal rejection.RESULTS: Of 76 Wistar rat acceptors, 5 rats were dropped out, among which, 1 rat was died accidentally after operation in the experimental group, 2 rats were died accidentally after operation in the control and 2 rats were injured cornea on the operated eyes due to fighting. But by supcomplications after corneal transplantation: In the experimental group, the number with anterior adhesion of sclera, non-round pupil; limited wound healing and non-formation of anterior chamber was lower than that in the implant tissue and corneal rejection: the survival time of corneal implant tissue was similar basically in both experimental group and the control [(8.9±2.3), (8.6±2.3) days, P ＞ 0.05]. Rejection presented in both groups in 16 days after corneal transplantation and the incidence of rejection was 100%.CONCLUSION: With stitches maintained and without intervention, the acute rejection is similar in rat corneal transplantation and human corneal transplantation. It is explained in the experiment that 8 stitches in corneal transplantation in which the rat implant tissue of 3.5 mm matches graft foreman of 3.0 mm can reduce the complications of rat corneal transplantation and becomes a satisfactory animal model of corneal transplantation.Skillful microscopic operation techniques, satisfactory operation instruments and adequate amplilfied pupil can reduce to the most extent the postoperation complications in rats.

Objective To investigate the relationship between pregnancy-associated plasma protein A(PAPP-A)level and restenosis after elective coronary stenting by coronary artery angiography(CAG)and intravascular ultrasound(IVUS). Methods The study consisted of 132patients with successful coronary stent placement:left anterior descending coronary artery(LAD)62,left circumflex coronary artery(LCX)36,right coronary artery(RCA)34.The follow-up CAG and IVUS were Derformed at the 6th month after stent placement.Diameter stenosis≥50%on CAG was regarded as in-stent restenosis.Neointimal areas(IA),stent volume(SV)and neointimal volume(IV)were measured by IUVS during follow-up.According to the PAPP-A level,lesions were divided into 2groups:high PAPP-A group(PAPP-A level≥12.11 mIU/L)and low PAPP-A group(PAPP-A level＜12.11 mIU/L). Results Total restenosis rate was 31.8%.There were no significant differences in age.sex and risk factors of coronary heart disease(hypertension,diabetes,smoking)between restenotic and nonrestenotie groups(all P＞0.05).The restenotic group had higher PAPP-A level than nonrestenotic group[(18.14±2.26)mIU/L vs. (10.95±2.12)mlU/L,P＜0.01].Angiographic restenosis occurred in 28 of 66 lesions(42.4%)in the high PAPP-A group and in 14 of 66 lesions(21.2%)in the low PAPP-A group(P＜0.01).Plasma PAPP-A level was positively correlated with IA,IV(r=0.47 and 0.54 respectively,all P＜0.05). Conclusions Elevated PAPP-A level is correlated well with the severity of the intimal hyperplasia.Plasma PAPP-A level affects restenosis after elective stent placement by promoting intimal hyperplasia.

Objective To investigate the expression of nuclear factor kappa B(NF-?B) in carotid artery of hypercholesterolemic rabbits injured by balloon and its relationship with intimal hyperplasia.Methods Twenty-five New Zealand male rabbits were fed with atherogenic diet and balloon injury was conducted in right carotid artery 4 weeks later.The rabbits were killed at the 6th hour,24th hour,1th week,2th week and 4th week,respectively.Blood samples and right carotid artery were collected in time and intimal hyperplasia was studied by histological morphology method.The expression of NF-?B was measured by in-situ hypridization(ISH).Results Intimal hyperplasia was present at the 7th day after balloon injury in hypercholesterolemic rabbits and it became more obvious with the increasing of the time.The intimal hyperplasia was not detected in the media area.The intima/media ratio was increased as time went on.The expression of NF-?B mRNA was observed in the carotid atery of hypercholesterolemic rabbits at the 6th hour after balloon injury and the expression reached its peak at the 2th week.The expression of NF-?B was much higher in injury group than that of control group.Conclusion The expression of NF-?B is up-regulated in carotid artery of hypercholesterolemic rabbits injured by balloon,which is involved in the inflammatory reaction and restenosis caused by balloon injury.

PURPOSE: This study aimed to describe the system of continuing medical education (CME) in the Guangxi Zhuang Autonomous Region and to ascertain the perceived needs related to that system, in order to improve the performance of health professionals in Chinese township health centers (THCs). METHODS: In-depth key informant interviews were conducted to gain insights into the current CME system. A cross-sectional survey using a self-administered structured questionnaire was also carried out from March to August 2014 in order to identify perceived needs among THC personnel in the Guangxi Zhuang Autonomous Region. Logistic regression was used to identify factors related to respondents' interest in pursuing different levels of degree study. RESULTS: The areas of need perceived by the respondents included general clinical competence and emergency or first aid knowledge. Most respondents wanted to study at medical colleges in order to obtain a higher degree. Respondents aged below 45 years with neutral or positive attitudes about the benefit of degree study for the licensure examination were more likely to attend a bachelor-level CME program than their older peers and respondents with negative attitudes towards degree study. Female respondents and respondents aged below 45 years were more likely to attend a junior college CME program than males and older respondents, respectively. CONCLUSION: It is necessary to develop degree-linked CME programs to meet the need for young health professionals in Chinese THCs; therefore, this programs can improve the expertise of poorly educated young health workers, who overwhelm rural Chinese heath systems.

OBJECTIVE: To explore the cause of cardiac perforation and tamponade during cardiac catheterization and intervention and to evaluate the effectiveness of the emergency treatment for tamponade in our hospital. METHODS: The clinical data from 23, 319 patients who received diagnostic catheterization or therapeutic procedures were analyzed retrospectively. RESULTS: Cardiac perforation and cardiac tamponade were observed in 22 of the 23, 319 patients during catheter procedures. It includes 1 in coronary artery angiography, 9 in percutaneous balloon mitral valvuloplasty, 3 in diagnosis, 2 in congenital heart disease intervention, 2 in pacemaker implantation, 2 in atrial fibrillation ablation and the other 3 in coronary revascularization. The occurrence of cardiac perforation in 11 patients was related to puncture of the interatrial septum and/or the procedure in the left atrial procedure and 2 were related to high pressure injection. Seventeen patients were found cardiac tamponade in the process of catheterization, and 5 were found at 2-14 h after operation. Pericardiocentesis and pericardial catheter drainage were performed in 20 patients and 11 of them succeeded. Among the other 11 patients, 7 were successfully saved by thoracotomy and 4 died. CONCLUSION Cardiac tamponade is a severe and fatal complication that may occur in different catheter procedures. Early prevention and diagnosis and performingperi cardiocentesis and drainage timely are critical to reduce the mortality.

Objective:To investigate the effects of docetaxel for postoperative chemotherapy of advanced gastric cancer.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 311 patients with advanced gastric cancer who were admitted to Lanzhou University Second Hospital from January 2013 to December 2018 were collected. There were 224 males and 87 females, aged from 26 to 82 years, with a median age of 58 years. Of 311 patients, 204 cases undergoing chemotherapy with the FOLFOX regimen (oxaliplatin, calcium folinate, 5-fluorouracil) were allocated into the FOLFOX group, and 107 cases undergoing chemotherapy with the FLOT regimen (docetaxel, oxaliplatin, calcium folinate, 5-fluorouracil) were allocated into the FLOT group. Observation indicators: (1) the propensity score matching conditions and comparison of general data between the two groups of patients after matching; (2) follow-up; (3) analysis of survival factors; (4) subgroup analysis; (5) adverse reactions. Follow-up was performed using a combination of outpatient examination, hospitalization review and telephone interview to detect situations of patients chemotherapy, postoperative survival, tumor recurrence and metastasis up to February 2019. The propensity score matching was realized using the nearest neighbor method with 1: 1 ratio and caliper setting as 0.02. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability method. Rank data was analyzed using non parametric Rank sum test. The survival curve and rate were respectively drawn and calculated using the Kaplan-Meier method. The survival analysis was done using the Log-rank test. Univariate analysis and multivariate analysis were conducted using the COX regression model. Subgroup analysis was done using interaction test. Results:(1) The propensity score matching conditions and comparison of general data between the two groups of patients after matching: 198 of 311 patients had successful matching, including 99 in each group. Cases with tumor differentiated as poorly differentiation or well differentiation, cases with CA19-9 <27 U/mL or ≥27 U/mL, cases with CA125 <35 U/mL or ≥35 U/mL before propensity score matching were 109, 95, 156, 48, 186, 18 in the FOLFOX group, and 42, 65, 93, 14, 104, 3 in the FLOT group, respectively, showing significant differences in the above indicators between the two groups ( χ2=5.649, 4.798, 4.039, P<0.05). After propensity score matching, the above indicators were 44, 55, 85, 14, 96, 3 in the FOLFOX group, and 42, 57, 85, 14, 96, 3 in the FLOT group, respectively, showing no significant difference in the above indicators between the two groups ( χ2=0.082, 0.000, 0.000, P>0.05). (2) Follow-up: 198 patients of the two groups after matching were followed up for 2 to 69 months, with a median follow-up time of 38 months. During the follow-up, 92 cases survived without tumor, 2 cases underwent tumor recurrence or metastasis, and 104 cases died including 103 with tumor related death and 1 case with non-tumor related death. The courses of chemotherapy were 5.6±0.7 and 5.4±0.8 for the FOLFOX group and FLOT group, respectively, showing no significant difference between the two groups ( t=1.651, P>0.05). The 1, 3, and 5-year cumulative survival rates of patients were 72.2%, 31.5%, 27.7% and 83.2%, 42.8%, 38.2% for the FOLFOX group and FLOT group, respectively. The median overall survival time were 21 months and 34 months for the FOLFOX group and FLOT group, respectively, showing significant difference between the two groups ( χ2=4.473, P<0.05). (3) Analysis of survival factors: results of univariate analysis showed that cases undergoing chemotherapy with the FLOT regimen, cases with tumor as diffuse type of Lauren classification, cases with tumor as mixed type of Lauren classification, cases with tumor differentiated as well differentiation, cases with tumor diameter≥5 cm, cases with CA19-9≥27 U/mL, cases with carcinoembryonic antigen (CEA)≥3.4 μg/L, cases with tumor as T4 stage of T staging, cases with tumor as N2 stage of N staging, cases with tumor as N3 stage of N staging, cases undergoing distal gastrectomy and cases undergoing total gastrectomy were related factors influencing postoperative survival of patients ( hazard ratio=0.659, 1.617, 1.798, 0.672, 1.726, 1.655, 1.942, 2.036, 2.536, 4.085, 1.810, 2.310, 95% confidence interval: 0.444-0.978, 1.024-2.556, 1.105-2.926, 0.457-0.990, 1.159-2.569, 1.006-2.723, 1.295-2.912, 1.190-3.484, 1.409-4.564, 2.491-6.697, 1.020-3.211, 1.261-4.233, P<0.05). Results of multivariate analysis showed that cases undergoing chemotherapy with the FLOT regimen, cases with CEA≥3.4 μg/L, cases with tumor as N2 stage of N staging and cases with tumor as N3 stage of N staging were independent risk factors influencing postoperative survival of patients ( hazard ratio=0.622, 1.732, 2.217, 4.039, 95% confidence interval: 0.418-0.926, 1.124-2.670, 1.200-4.097, 2.448-6.662, P<0.05). (4) Subgroup analysis: results of subgroup analysis showed that of the different subgroups using gender, age, tumor Lauren classification, tumor differentiation degree, tumor location, tumor diameter, tumor markers, tumor T staging, tumor N staging and surgical procedures as subgrouping index, the efficacy difference between the FLOT group and the FOLFOX group was the same (interaction P>0.05). (5) Adverse reactions: the incidence of grade Ⅲ-Ⅳ adverse reactions of leukopenia, anemia, thrombocytopenia, nausea, vomiting and liver and kidney dysfunction were 11.1%(11/99), 2.0%(2/99), 3.0%(3/99), 12.1%(12/99), 4.0%(4/99), 1.0%(1/99) and 34.3%(34/99), 1.0%(1/99), 9.1%(9/99), 24.2%(24/99), 4.0%(4/99), 0 in the FOLFOX group and the FLOT group, respectively. There were significant differences of the incidence of leukopenia and nausea between the two groups ( χ2=15.213, 4.889, P<0.05). There was no significant difference of the incidence of thrombocytopenia between the two groups ( χ2=3.194, P>0.05) and there was no significant difference of the incidence of anemia, vomiting and liver and kidney dysfunction between the two groups ( P>0.05). There was no patient in the two group withdrawal from chemotherapy as no tolerance to toxic reactions. All patients were treated with glucocorticoids, proton pump inhibitors and serotonin receptor antagonists during chemotherapy. Patients undergoing leukopenia were treated with granulocyte stimulating factor. Conclusions:Compared with FOLFOX regimen, FLOT regimen which adds docetaxel significantly prolongs the postoperative median overall survival time of patients with advanced gastric cancer. However, FLOT regimen increases the incidence of grade Ⅲ-Ⅳ adverse reactions of leukopenia and nausea.

OBJECTIVETo evaluate the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) in children with pancreaticobiliary diseases and the characteristics of pancreaticobiliary disorders in children.

METHODRetrospective review was conducted on the data of patients younger than 18 years who underwent ERCP between 2005 and 2012 at West China Hospital. The indications,ERCP findings, ERCP procedures, complications, and clinical outcomes were evaluated.ERCP procedures were performed using standard duodenoscopes under general anaesthesia or sedation, which included all endoscopic treatments, such as endoscopic sphincteropapillotomy, stone extraction, stent treatment and so on.

RESULTOne hundred and two ERCPs were performed on 68 patients, and all the procedures were successfully completed in 100% cases. There were 39 girls (57%), and median age at time of procedure was 14.6 years (range, 5-17 years).General anesthesia and sedation were performed in 81% and 19% of procedures, respectively. The ERCP findings were classified as follows:bile duct stone(s) (n = 37, 54%), pancreatic duct stone(s) (n = 8, 12%), bile duct benign stricture (n = 7, 10%) and other nonmalignant pancreaticobiliary diseases (n = 16, 24%).Four cases (4/102, prevalence 4%) were complicated with post-ERCP pancreatitis.Symptoms such as abdominal pain and jaundice were cured obviously after the procedures of ERCP were performed.

CONCLUSIONThe main characteristics of pancreaticobiliary disorders in children were nonmalignant pancreaticobiliary diseases, such as bile duct stone, pancreatic duct stone, and bile/pancreatic duct benign stricture.When performed by well-trained endoscopists, ERCP is safe and effective in children.
