Objective To evaluate the influence of L-ornithine-L-aspartate (LOLA) on model for end stage liver disease(MELD) score and liver function of patients with chronic liver failure (CLF). Methods Sixty patients consecutively admitted to our hospital from May, 2002 and November, 2008 were enrolled into the study and randomly divided into low dose group (LD group, LOLA:10 g/d) and high dose group (HD group, LOLA :20 g/d)After treatment of LOLA, the clinical data ( serum NH3 , MELD score and liver function ) were compared between the two groups. Results Compared to serum NH3 level before treatment, serum NH3 decreased ( 62.59 + 27.87 )μmoL/L in the HD group and (49.36 + 27.34 ) μmol/L in the LD group, and both decreasements were statistical significant (Ps ＜ 0. 05 ). Compared to MELD before treatment, MELD score decreased ( 8.38 ± 2. 24 ) and ( 14.57 + 7.68), respectively ( Ps ＜ 0.05 ). Compared to LD group, all indices of liver function in the HD group improved more compared to those of the LD group ( Ps ＜ 0.05 ). Conclusions LOLA could significantly decrease serum NH3 and MELD score and improve liver function in CLF patients.

Objective To analyze factors associated with long-term survival of acute leukemia(AL). Methods Clinical data is analyzed in 27 leukemia cases who had at least 5 years free survival (EFS). Combined intensive chemotherapy was administered under the principle of individualization to induce remission.Regular consolidation treatment after remission was strictly continued.Long-term follow up Was kept on,with the therapeutic regimen modified accordingly.Results Complete remission(CR) was achieved in 112 of 143(78.3%)AL patients and 27(18.9%)of them had survived more than 5 years.Conclusion The long-term survival of AL patients is related to the type of AL,leukemia cell burden,extramedullary leukemia, individual treatment,time required to achieve CR,continuous intensive chemotherapy and the regular postremission treatment.

OBJECTIVE To investigate the effect of recombinant human granulocyte colony-stimulating factor(rhG-CSF) combined with antifungal drugs in the treatment of malignant hematologial diseases with fungus infection.METHODS Malignant hematologial patients with fungus infection were randomized to receive fluconazole with or without rhG-CSF.(RESULTS) The response rate in patients who received fluconazole combined with rhG-CSF was 89.1% and in(control) patients was 62.8%(P

Objective To compare conventional T2-weighted MR cholangiography (T2WI-MRC) with gadobenate dimeglumine enhanced T1-weighted MR cholangiography(CE-MRC) for evalution of biliary anatomy in liver transplant donor candidates. Methods Thirty-two healthy liver transplant donor candidates were examined with two MR cholangiogaphic methods. For T2WI-MRC, a three-dimensional turbo spin-echo sequence and oblique coronal heavily T2-weighted thick-slab turbo spin-echo imaging sequence were performed. For CE-MRC, three-dimensional fat-suppressed spoiled gradient-echo sequences were performed, with a time delay of 60 minutes following the administration of gadobenate dimeglumine. To compare the depiction of biliary duct anatomy and the artifact caused by intestinal liquid and breathing between the two methods. Intraoperative cholangiography was the reference-standard examination. Results The both methods depicted the biliary anatomy correctly in all 9 cases. The both methods showed the third branches of intrahepatic biliary duct clearly. T2WI-MRC showed interhepatic bihary duct before the third branches in 28 cases (87.5%), CE-MRC showed the same finding in 14 cases (43.8% ). T2WI-MRC showed common bile ducts intermitantly in 2 cases, which were normal in CE-MRC and intraoperative cholangiography. Intestinal liquid affected the image quality of biliary duct in 6 cases (18.8%) performed with T2WI-MRC, but none with CE-MRC. The artifacts caused by breathing were not obvious in the either method. Conclusion T2WI-MRC and CE-MRC both can be used to evaluate bihary anatomy of liver transplant donor candidates, but CE-MRC appears to be more accurate than T2WI-MRC.

Objective To investigate clinical significance of transforming growth factor-beta 1 ( TGF-β1 ) in patients with chronic idiopathic thrombocytopenic purpura(CITP). Methods The serum level of TGF-β1 in 38 pa-tients with initial CITP were detected using enzyme-linked immunosorbent assay(ELISA). Results The serum level of TGF-β1 in initial patients with CITP was significantly higher than that of the controls [( 132.57±5.17) μg/L vs ( 76.81±4.42) μ/L] ( P <0.01 ). The serum level of TGF-β1 in those having good response after therapy was sig-nificantly lower than before treatment[(81.26±3.78)μg/L] (P <0.01 ). There was no difference in TGF-β1 be-tween nonremission [(123.49 ± 4.31 ) μg/L] and initial patients (P > 0.05 ). There was negative correlation between TGF-β1 and platelet count(r = -0. 342 ,P < 0.05 ) ,there was positive correlation between TGF-β1 and megakaryo-cyte count (r = 0.409, P < 0.01 ). Conclusions TGF-β1 partakes in the pathogenesis of CITP, the determination of which in patients with CITP is useful to judge the state of illness, which can be regarded as an assistant index of cur-ative effect.

Objective: To investigate the difference in the clinical efficacy by thoracoscopy or thoracotomy for treating esophageal atresia. Methods: Thirty-one cases of type-Ⅲ esophageal atresia undergoing surgical treatment from February 2015 to May 2018 at the Department of Pediatric Surgery of Fujian Provincial Maternity and Children′s Hospital were included, and according to the different surgical methods they were divided into thoracoscopic group (15 cases) and thoracotomy group (16 cases). The operation duration, blood loss, postoperative chest drainage time, posto-perative hospital stay and postoperative complications were analyzed between 2 groups. Results: The mean time of operation was (181.33±13.86) min in the thoracoscopic surgery group and (139.06±10.98) min in the thoracotomy group, the thoracoscopic group had longer operation duration than thoracotomy group, and there was a significant difference in operation duration between two groups (t=9.44, P=0.000); mean blood loss was (3.07±0.96) mL in the thoracoscopic surgery group and (5.06±1.12) mL in the thoracotomy group, the thoracoscopic group had less amount of blood loss than thoracotomy group, and there was a significant difference in blood loss between two groups(t=-5.29, P=0.000); mean postoperative chest drainage time was(11.67±1.34) d in the thoracoscopic group and (12.25±1.06) d in the thoracotomy group, and there was no significant difference in postoperative chest drainage time between two groups(t=-1.34, P=0.19); mean time of postoperative hospitalization time was(15.20±0.94) d in the thoracoscopic group and (16.00±0.96) d in the thoracotomy group, and there was a significant difference in the postoperative hospitalization time between two groups (t=-2.33, P=0.027); the anastomotic leak rates were 33.33% (5 cases) versus 25.00% (4 cases) with closed or open approaches, respectively; anastomotic stricture rates were 40.00%(6 cases) versus 31.25% (5 cases) with closed or open approaches, respectively.There was no significant difference in postoperative incidence of anastomotic fistula and anastomotic stenosis between two groups. Conclusions Compared with thoracotomy in the treatment of esophageal atresia, thoracoscopic approach has smaller incision and less bleeding, less chest deformity, short hospital stay postoperatively, so it is safe and effective.However, the surgeon must have experience in doing thoracoscopic operation.

Objective To analyze the law of the mid﹣term hepatic hemodynamics after liver transplantation and to investigate its relationship with liver function. Methods A total of 56 recipients underwent liver transplantation in the Affiliated Hospital of Qingdao University from February 2014 to October 2015 were studied,and divided into normal group (n =24)and abnormal group (n =32)according to the liver function.General information and liver function of both groups were recorded.Furthermore,hepatic artery peak velocity (HAP),portal vein peak velocity (PVP)and portal vein flow (PVF)before the liver transplantation and on postoperative day 1,30 and 90 were measured through ultrasonic detection;hepatic arterial buffer capacity (BC)and adjustment BC were calculated.The univariable and multivariable analysis were performed to analyze the relationship between hepatic hemodynamics and liver function in two groups,and the receiver operating curve (ROC)was drawn. Results The PVP and PVF on postoperative day 30 in abnormal group were significantly higher than those of normal group (P =0.014,0.049).The BC and adjustment BC in normal group were significantly higher than those of abnormal group (P =0.048,0.011).The multivariable analysis showed that adjustment BC was the independent risk factor (P =0.047),with the area under the curve (AUC)of ROC of 0.705,sensitivity of 0.652 and specificity of 0.750. Conclusions PVP,PVF,BC and adjustment BC on postoperative day 30 may be related to abnormal liver function,of which adjustment BC can be used as one of the indicators for diagnosis and intervention of abnormal liver function.

Objective To investigate the incidence of de novo malignant tumors of the digestive system after liver transplantation (LT) in China. Methods Relevant literature review was performed from Wanfang data, China National Knowledge Infrastructure (CNKI) and Chongqing VIP. The retrieval time started from the establishment of each database to May 9, 2019. The Chinese search terms were liver transplantation+ postoperative/de novo+ malignant tumor/cancer. The age distribution, sex composition, time of diagnosis, involved organs, treatment and clinical prognosis of recipients with de novo malignant tumors of the digestive system after LT in China were retrospectively analyzed. Results After literature screening, 16 articles were eventually selected including 47 cases of de novo malignant tumors of the digestive system after LT. A majority of them were male recipients. The age of the recipients was 51 (23-65) years old, most of them were middle age (45-59 years old). The average time of diagnosis of de novo malignant tumors of the digestive system after operation was 43 (2-156) months, with the highest number of cases within postoperative 1-3 years. Colon and stomach were the most common tumor sites. Surgery combined with radiotherapy and chemotherapy remained the main treatment option. However, the overall clinical prognosis of patients with de novo malignant tumors of the digestive system after LT was poor with a mortality rate of 51%. Conclusions In China, colon cancer and gastric cancer are the main de novo malignant tumors of the digestive system after LT. The overall clinical prognosis of patients with de novo malignant tumors of the digestive system is poor. Sufficient attention should be paid to postoperative monitoring and prevention.
