Objective To evaluate the usage of renoportal anastomosis in the liver transplanta- tion.Method The successful experience about renoportal anastomosis for portal vein reconstruction in liver transplantation was reported,and related literature reviewed.Results Including our case,there have been 13 cases of liver transplantation using renoportal anastomosis for portal vein reconstruction. Among these patients,8 cases were complicated with diffuse portal vein thrombosis,and 10 cases had a splenorenal shunt(spontaneous shunt in 3 and surgical shunt in 7).Complications related to portal vein hypertension occurred in 3 cases(transient ascites in 2 cases and severe digestive bleeding in 1 case)after liver transplantation.There were 3 deaths which were not related to renoportal anastomo- sis.Conclusion Renoportal anastomosis is a safe and feasible technique in liver transplantation for the patients with diffuse portal vein thrombosis or with splenorenal shunt(spontaneous or surgical shunt).

Objective To analyze the application effects of artificial intelligence (AI) software and Mimics software in preoperative three-dimensional (3D) reconstruction for thoracoscopic anatomical pulmonary segmentectomy. Methods A retrospective analysis was conducted on patients who underwent thoracoscopic pulmonary segmentectomy at the Second People's Hospital of Huai'an from October 2019 to March 2024. Patients who underwent AI 3D reconstruction were included in the AI group, those who underwent Mimics 3D reconstruction were included in the Mimics group, and those who did not undergo 3D reconstruction were included in the control group. Perioperative related indicators of each group were compared. Results A total of 168 patients were included, including 73 males and 95 females, aged 25-81 (61.61±10.55) years. There were 79 patients in the AI group, 53 patients in the Mimics group, and 36 patients in the control group. There were no statistical differences in gender, age, smoking history, nodule size, number of lymph node dissection groups, postoperative pathological results, or postoperative complications among the three groups (P>0.05). There were statistical differences in operation time (P<0.001), extubation time (P<0.001), drainage volume (P<0.001), bleeding volume (P<0.001), and postoperative hospital stay (P=0.001) among the three groups. There were no statistical differences in operation time, extubation time, bleeding volume, or postoperative hospital stay between the AI group and the Mimics group (P>0.05). There was no statistical difference in drainage volume between the AI group and the control group (P=0.494), while there were statistical differences in operation time, drainage tube retention time, bleeding volume, and postoperative hospital stay (P<0.05). Conclusion For patients requiring thoracoscopic anatomical pulmonary segmentectomy, preoperative 3D reconstruction and preoperative planning based on 3D images can shorten the operation time, postoperative extubation time and hospital stay, and reduce intraoperative bleeding and postoperative drainage volume compared with reading CT images only. The use of AI software for 3D reconstruction is not inferior to Mimics manual 3D reconstruction in terms of surgical guidance and postoperative recovery, which can reduce the workload of clinicians and is worth promoting.

OBJECTIVETo prepare monoclonal antibody (mAb) against prM epitope.

METHODSThe gene encoding prM was isolated using RT-PCR from brain of JEV infected mouse and cloned into prokaryotic expression vector pET-32a. Recombinant plasmid was transformed into E.coli BL21/DE3/LysS, then the transformed cells were expressed with the induction of IPTG. The expression and purification of the prM protein was analyzed by SDS-PAGE. The BALB/c mice were immunized with purified prM protein. Hybridoma cell lines secreting monoclonal antibodies against prM were established after cell fusion of mouse splenic cell and P3-X63-Ag8.653 cells. The specificity of mAb was identified by ELISA, Western Blot and Immunohistochemistry assay.

RESULTSmAb against prM epitope of JEV was prepared successfully.

CONCLUSIONThe obtained prM specific mAb was valuable for the prevention and dignosis of Japanese encephalitis.

OBJECTIVESTo study the relationship between HBV genotypes and the efficacy of antiviral therapies.

METHODSHBV genotypes of 90 hepatitis B e antigen positive patients with chronic hepatitis B (CHB) were determined by PCR sandwich hybridization-ELISA technique. Forty-one patients with CHB were treated with lamivudine (100 mg/day) for 48 weeks and 49 patients with CHB were given alpha-interferon (3 MU/QOD) therapy for 48 weeks. The serological, biochemical and virological symbols were measured before, during and after treatment for all the patients.

RESULTSOf the 90 patients, genotype B HBV was found in 16 and C in 74. There was no difference in the rate of response to lamivudine treatment between patients with genotype B or C HBV (33.3% vs. 20.0%) after 48 weeks treatment with lamivudine in the 41 patients. Of the 49 HBeAg positive CHB patients treated with alpha-interferon for 48 weeks, in HBV genotype B and C patients the rates of normalization of ALT were 60.0% and 20.5%; the rate of HBeAg turning to negativity was 50.0% and 17.9%; and the rate of HBV DNA undetectability was 50.0% and 17.9%. The rate of response to the interferon treatment was significantly higher in patients with HBV genotype B compared to those with genotype C.

CONCLUSIONSOur study shows that there is no influence on the lamivudine treatment effects for the HBV genotype B and C CHB patients, but the alpha-interferon treatment for HBV genotype B CHB patients is more effective than that for the genotype C ones.

OBJECTIVETo compare the clinical results of early and delayed intramedullary nailing and locked plating for the treatment of multi-segments tibial fractures of type AO/ASIF-42C2.

METHODSBetween January 2010 and January 2013,45 patients with multi-segments closed tibial fractures of AO/ASIF-42C2 were treated by early primary intramedullary nailing and locked plating in 20 cases as early group and delayed in 25 cases as delayed group. In early group,20 cases included 13 males and 7 females with an average age of (37.9±14.3) years old ranging from 20 to 56 years;according to soft tissue injury Tscherne classification, 8 fractures were frade I,12 were grade II. In delayed group, 25 cases included 17 males and 8 females with an average age of (38.7±17.2) years old ranging from 24 to 55 years,4 fractures were grade I ,19 were grade II ,2 were grade III. The operative time, blood loss, hospital stay,fracture healing time and complications were recorded. At final follow-up, the Johner-Wruhs score were used to evaluate functional efficacy, and the posterior-anterior and lateral X-ray to evaluate fracture reduction and alignment.

RESULTSAll the patients were followed up for (12.5±2.5) months in early group and (13.2±2.8) months in delayed group (P>0.05). No wounds infections were happened. At the last follow-up, the mean range of knee joint was 10°-0°-120°. According to Johner-Wruhs scoring,there were 15 cases in excellent,3 in good,fair in 2 in early group; 21 in excellent,2 in good,2 in fair. The average operative time,blood loss had no significant differences between two groups (P>0.05), but hospital stay in early group was significantly shorter than those in delayed group(P<0.05). Average fracture healing time of early group and delayed group were (5.3±2.6) months and (6.0±2.9) months, respectively (P>0.05).

CONCLUSIONFor multi-segments tibial fractures of type AO/ASIF-42C2 with preoperative minor soft tissue injuries lighter of Tscherne grade I or II, early primary intramedullary nailing and locked plating does not significantly increase the postoperative incidence of soft tissue complications for patients. The early and delayed primary intramedullary nailing and locked plating for treatment of AO/ASIF-42C2 proximal third tibial fractures can get similar curative effect.

OBJECTIVE: To analyze the main pathogens of infection after the liver transplantation and their antibiotic resistant patterns. METHODS: The main pathogens of infection after the liver transplantation were retrospectively analyzed. Using 3-dimensional tests, ESBLs (extended-spectrum beta-lactamase), and AmpC were detected among the Gram negative bacilli. beta-Lactamase and Van gene in Enterococcus were determined by the standard agar dilution susceptibility tests and Nitrocefin respectively. RESULTS: The main infected strains were Enterococcus faecalis (15.0%), Enterobacter cloacae (13.9%), fungus (13.3%), and Escherichia coli (10.7%) after the liver transplantation. Among them, 32.4% of Enterobacter cloacae and 36.8% of Escherichia coli produced ESBLs; 33.8% of Enterobacter cloacae and 10.5% of Escherichia coli. produced AmpC beta-lactamases. The detectable rate of VanA gene in Enterococcusfaecalis and Enterococcus faecium was 7.5% and 11.1%; VanB was 3.8% and 7.4%; VanC was 1.3% and 0, respectively. CONCLUSION The infection mainly occurs in the intestinal tract after the liver transplantation. The production of ESBLs and AmpC beta-lactamases is the main mechanism of antibiotic resistance. The increased detectable rate of vancomycin-resistant Enterococcus should be paid attention to.

OBJECTIVETo investigate the donor evaluation, surgical protocol, and the complication for the adult-to-adult living donor liver transplantation (AALDLT).

METHODSThere were 94 cases of AALDLT were performed by the same surgical team from January 2007 to August 2010. Patients aged from 18 to 74 years. Donors aged from 19 to 60 years. All the 94 cases' operation protocol as following, 2 cases with left lobe liver graft, 92 cases with right lobe graft, 44 cases with middle hepatic vein (MHV) harvested, and 48 cases without MHV. Assessment methods of donors, postoperative complications and the current survival were analyzed.

RESULTSAll the donors were discharged with good recovery, complication incidence of donor was 7.4%. Median time of follow-up was 37 months. Eight patients were died during follow-up, 1-year patient survival rate was 95.7%, and graft survival rate was 94.4%. One case complicated with small-for-size syndrome, 1 case was performed re-transplantation for acute hepatic necrosis, 24 patients (25.5%) showed biliary anastomotic stenosis defined cholangiography or magnetic resonance cholangiopancreatography examination, and 9 patients (9.6%) showed abnormal liver function.

CONCLUSIONSLiving donor liver transplantation is an effective treatment method for end-stage liver disease, with accurate evaluation preoperative, a reasonable surgical approach, whether using the left or right lobe liver graft, with or without middle hepatic vein in AALDLT can effectively ensure the donor and recipient safety.

OBJECTIVESTo analyze the survival rate of orthotopic liver retransplantation (Re-OLT) and identify the variables predicting the outcome.

METHODSA retrospective analysis of 74 Re-OLT patients from January 1999 to December 2005 was performed. The univariate analysis of Kaplan-Meier model was used to investigate the relativity between the factors and survival rate, and COX regression model was used in multivariate analysis to identify the prognostic factors for survival.

RESULTSThe total incidence rate of Re-OLT was 5.7%, and overall patient survival rates at 1 month, 3 month, 1 year and 2 year were 82.4%, 73.8%, 71.9% and 68.5%, respectively. There were 10 factors might influence the survival rate by Kaplan-Meier model, such as the period of Re-OLT, stage of hepatic encephalopathy, prothrombin time, total bilirubin, warm ischemia time, operative surgical procedure, quantity of blood lost during operation, days staying in the intensive care unit (ICU), infection and complications after Re-OLT. And three factors among them were identified as independent prognostic factors for survival by multivariate model: operative surgical procedure, days staying in the ICU and complications after Re-OLT.

CONCLUSIONThe surgical procedure, duration in ICU and complications after Re-OLT are strong predictors for survival after Re-OLT.

OBJECTIVETo prove the therapeutic effect of ginger-partitioned moxibustion on leukopenia induced by chemotherapy and effect on life quality of the patient with tumor after chemotherapy.

METHODSRandomized, controlled, multi-central cooperative method was used and the patients confirmed to the enrolled criteria were divided in-to two groups. The test group were treated with ginger-partitioned moxibustion at Dazhui (GV 14), Geshu (BL 17), Pishu (BL 20), etc.; and the control group with oral administration of Chinese patent medicine.

RESULTSOut of the 221 cases confirmed to program analysis, 113 cases were in the test group and 108 cases in the control group. After 10 days, the cured rate and the effective rate were 84.1% and 66.4% in the test group and 35.2% and 33.3% in the control group, respectively, with very significant differences between the two groups (both P < 0.01); fifteen days later, the therapeutic effects in the two groups were maintained. The two methods could improve clinical symptoms, with the test group being better than the control group. Any adverse response was not found in the two groups, and the injuries of functions of the heart, lung and kidney induced by chemotherapy had some improvement.

CONCLUSIONThe therapeutic effect of ginger-partitioned moxibustion on luekopenia induced by chemotherapy is reliable and is better than oral administration of Chinese patent medicine, with a better duplication.
