Chinese Journal of Hepatobiliary Surgery 2011;17(10):829-832
Objective To analyze the surgical management and prognosis of hilar cholangiocarcinoma(HCC).MethodClinical data of 72 patients with HCC were retrospectively analyzed.Results There was a significant difference in the 3- and 5- year survival rates and median survivals among the groups treated with different surgical methods(x2 =28.1,P< 0.01 ).Univariate analyses conducted for the 16 factors which might affect prognosis showed the surgical method,lymphatic metastasis,positive margin,as well as the type of pathology and staging were of statistically significant prognostic value (P<0.05).On a multivariate analysis using the Cox proportional hazards model,surgical management,lymphatic metastasis and the type of pathology and staging were independent prognostic factors (regression coefficient 1.4157,1.1072,1.6435).ConclusionRadical excision is an important prognostic factor for HCCa and extended resection improved the long-term survival rates of radical surgery.

Objective:To investigate the value of anti-hexokinase1 antibodies (anti-HK-1) and anti-kelch-like 1 antibodies (anti-KLHL12) antibody in evaluating ursodeoxycholic acid (UDCA) response in patients with primary biliary cholangitis (PBC).Methods:112 PBC patients who had been treated with UDCA for more than 12 months with relatively complete clinical data were analyzed. Serum was collected and the expression of anti-mitochondrial antibody (AMA), anti-HK-1 and anti-KLHL12 antibodies were detected by ELISA. The response to UDCA was based on Paris standard. According to the expression of new antibodies, the patients were divided into the new antibody positive group and negative group. In addition, PBC related baseline indicators were collected, and Spearman correlation analysis was used to study the correlation between antibody expression and baseline indicators in PBC patients.Results:Positivity of anti-HK1 and anti-KLHL12 antibody in AMA-positive PBC patients were 44.7% and 41.2% respectively. Positivity of anti-HK1 and anti-KLHL12 antibodies in AMA negative PBC patients were 33.3% and 22.2%. Anti-HK1 positive patients had higher serum levels of Alaninetransaminase (ALP), aspartate aminotransferase, (AST), γ-glutamyl transpeptidase (γ-GT) and total bilirubin (TBIL) compared with anti-HK1 negative patients, with statistical significant differences ( P<0.05). Notably, correlation analysis showed significantly positive correlation between anti-HK1 antibody expression and ALP, γ-GT and TBIL serum levels ( r=0.735, P<0.05; r=0.332, P<0.05; r=0.491, ( r=0.466, P<0.05). The UDCA response rate in anti-HK-1 antibody positive group was lower than that of the negative group (36.2% vs 60%; P<0.05). Conclusion:Anti-HK-1 and anti-KLHL12 antibody can help to diagnose PBC, and the expression of anti-HK-1 antibody is correlated with the severity of PBC, which could help to predict the reaction of PBC patients to UDCA.

Objective To investigate the significance of miR-193b to biological behaviors of hepatocellular carcinoma (HCC). Methods 48 cases of HCC specimens and corresponding adjacent tissues were collected, and the miR-193b expression levels in these specimens were measured by real-time quantitative PCR. The miR-193b expression was measured by the same way in HepG2 and SMMC-7721 cells. The HepG2 and SMMC-7721 were transfected with miR-193b mimics or negative control miRNA mimic with Lipofectamine 2000, and the non-transfected cells were taken as blank control. The proliferation ability of the HCC cells were detected by MTT method, and the apoptosis rate was tested by flow cytometry. Results The expression level of miR-193b in HCC tissues (2.441 ±0.569) was significantly lower than that in the corresponding adjacent tissues (15.488±4.326) (P < 0.05). Compared with normal liver cell line L-O2, the expression levels of miR-193b were significantly lower in HepG2 and SMMC-7721 cells. Transfected with miR-193b mimic, the proliferation ability of HepG2 and SMMC-7721 cells were reduced, while their apoptosis were increased. Conclusion miR-193b may be negative to regulate the proliferation of HCC and increase its apoptosis.

Objective To investigate the effect of acupuncture plus Chinese herbal medication on plasma endothelin (ET-1) and calcitonin gene-related peptide (CGRP) in child patients with mesenteric lymphadenitis.Methods One hundred and eighty child patients with mesenteric lymphadenitis were randomly allocated to groups A, B and C, 60 cases each. Group A received acupuncture at Zusanli and pricking Sifeng points plus oral administration of Wudang Babao Zijinding; group B, oral administration of amoxicillin and clavulanate potassium granules; group C, oral administration of Wudang Babao Zijinding alone. ET-1 and CGRP contents were measured in the three groups before and after treatment.Results There were statistically significant pre-/post-treatment differences in ET-1 and CGRP contents in group A (P<0.01). There were statistically significant post-treatment differences in ET-1 and CGRP contents between group A and group B or C (P<0.01).Conclusions Acupuncture plus Chinese herbal medication is an effective way to treat mesenteric lymphadenitis in children. It can regulate ET-1 and CGRP in the patients.

OBJECTIVETo explore the distribution of monoamine oxidase A (MOA-A) EcoRV polymorphism in Shanghai Han population and its possible role in the risk for Parkinson's disease(PD).
METHODSThe MAO-A gene EcoRV polymorphism was detected with PCR-RFLP method in 110 PD patients and 182 healthy controls, furthermore, statistical analysis was performed to investigate association between EcoR V polymorphism and PD onset.
RESULTS(1)Remarkable difference in MAO-A EcoR V polymorphic distribution has been observed between Shanghai Han population and that in North America. (2) Neither allelic frequency nor genotypic frequency in PD cases differs significantly from that in healthy controls regardless of data from male or female subclass.
CONCLUSIONThere may be racial difference in the distribution of the human MAO-A EcoR V (C/T) polymorphism, but the present research does not support the association between this variant and susceptibility to PD in Chinese Han population of Shanghai area.

Objective:To investigate the relationship between hyperuricemia and outcome in patients with acute ischemic stroke.Methods:Patients with acute ischemic stroke admitted to Department of Neurology, Putuo Hospital, Shanghai University of Tranditional Chinese Medicine between January 2020 and September 2020 were enrolled retrospectively. The modified Rankin Scale (mRS) score was used to evaluate the clinical outcome 3 months after the onset. ≤2 was considered as good outcome, and >2 was considered as poor outcome. The demography and baseline characteristics were compared between the good outcome group and the poor outcome group. Multivariate logistic regression analysis was used to determine the independent influencing factors of the outcome. Results:A total of 210 patients were included, their age was 69.87±62.62 years. There were 125 males (59.52%) and 85 females (40.48%). The baseline median National Institutes of Health Stroke Scale (NIHSS) score was 4. The serum uric acid level in 169 patients (80.48%) was normal and 41 (19.52%) had hyperuricemia; 120 patients (57.14%) had a good outcome, and 90 (42.86%) had a poor outcome. Blood glucose level, serum uric acid level, baseline NIHSS score and the proportions of diabetes mellitus, history of stroke or transient ischemic attack, hyperuricemia in the poor outcome group were significantly higher than those in the good outcome group (all P<0.05). Multivariate logistic regression analysis showed that diabetes mellitus (odds ratio [ OR] 2.735, 95% confidence interval [ CI] 1.461-5.121; P=0.002), hyperuricemia ( OR 2.400, 95% CI 1.102-5.228; P=0.027), and higher baseline NIHSS score ( OR 1.233, 95% CI 1.118-1.360; P<0.001) were the independent risk factors for poor outcome in patient with acute ischemic stroke. Conclusion:Hyperuricemia is an independent risk factor for poor outcome in patients with acute ischemic stroke.
