Significance of expressions of HDGF、VEGF and mucin 5B in hepatolithiasis associated with intrahepatic cholangiocarcinoma / 中华肝胆外科杂志

Objective:To study the roles of hepatoma-derived growth factor (HDGF), vascular endothelial growth factor (VEGF) and mucin 5B (MUC5B) in hepatolithiasis associated with intrahepatic cholangiocarcinoma (HICC).Methods:The clinical data and tissue specimens of 116 patients who underwent hepatectomy at the Third Affiliated Hospital of Wenzhou Medical University from October 1999 to October 2019 were retrospectively analyzed. There were 41 patients with HICC (the HICC group), 38 patients with intrahepatic cholangiolithiasis (the intrahepatic cholangiolithiasis group), and 37 patients with benign liver tumor who underwent hepatectomy (the control group). There were 47 males and 69 females, with age of (66.1±3.2) years old. The positive expressions of HDGF, VEGF and MUC5B in the three groups were compared. In 41 patients with HICC, the correlation between positive expressions of HDGF, VEGF and MUC5B with patients’ clinical characteristics were studied.Results:Compared with the control group, the positive expression rates of HDGF, VEGF and MUC5B in the HICC group and the intrahepatic cholangiolithiasis group were significantly increased, ( P<0.05). Compared with the intrahepatic cholangiolithiasis group, the positive expression rates of HDGF, VEGF and MUC5B in the HICC group were significantly increased ( P<0.05). Positive expression of VEGF in HICC patients was correlated with tumor differentiation, tumor local invasion, tumor length, tumor stage, tumor carbohydrate antigen CA19-9 level and lymph node metastasis ( P<0.05). Spearman correlation analysis showed that HDGF was positively correlated with VEGF expression in HICC tissues specimens ( r=0.935, P<0.01). Survival analysis showed that the cumulative survival rates (36.7%, 17.1%, 7.3%) of patients with positive expression of VEGF were significantly lower than that of patients with negative expression (51.2%, 26.8%, 19.5%) at 1, 3, 5 years after surgery ( P<0.01). The cumulative survival rate (34.1%, 17.1%, 4.9%) of patients with MUC5B positive expression were significantly lower than that of patients with negative expression (53.7%, 31.7%, 17.1%) at 1, 3, 5 years after surgery ( P<0.01). Conclusion:HDGF can be used as a reference indicator for early assessment of HICC. Overexpressions of VEGF and MUC5B can be used as important indicators for HICC in evaluating disease progression and prognosis.

Function of mucin 2, mucin 4 on lithogenic bile of calculus of intrahepatic duct / 中华肝胆外科杂志

Objective To investigate the function of mucin 2,mucin 4 on formation of lithogenic bile in patients with calculus of intrahepatic duct.Methods Bile duct mucosa,bile duct wall,bile and plasma were collected from 56 patients with calculus of intrahepatic duct (CID group) and 17 individuals without calculus of intrahepatic duct (control group).The bile duct wall was stained with mucin 2 (MUC2) and mucin 4 (MUC4).Reverse-transcription polymerase chain reaction (RT-PCR) was applied to study the mRNA expressions of MUC2 and MUC4 in the bile duct mucosa.The correlation of the bile duct and serum lipid index was analyzed.Results Serum lipid index in the CID group was significantly higher than control group (all P＜0.05).Biliary total bile acids and bile acids mol percentage were lower in the CID group than control group (both P＜0.05).The expressions of MUC2 was not increased significantly in CID group than the control group (all P＞0.05).The expressions of MUC4 were more significantly increased in CID group than the control group (P＜0.05).The mRNA of MUC4 in the CID group was also more significantly increased than in control group (P＜0.01).There were no correlations between MUC4 expression and the level of biliary total bile acid in the CID group (r=-0.374,P＜0.05).Conclusion The expression of MUC4 in patients with CID was enhanced,which promoted the absorption of bile acid by the mucosal epithelium of the bile duct,and caused a large amount of mucin to be secreted into bile,which may be related to the formation of stony bile.

Low expression of succinate dehydrogenase subunit B in locally recurrent nasopharyngeal carcinoma and implication for prognosis / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To study the expression of succinate dehydrogenase subunit B (SDHB) in the tissues of locally recurrent nasopharyngeal carcinoma (rNPC) and the correlation with the clinicopathological factors and prognosis of rNPC.</p><p><b>METHODS</b>Immunohistochemistry was used to detect the expression of SDHB in the tissues of primary and locally recurrent nasopharyngeal carcinoma. The relationship between SDHB expression and clinicopathological features was analyzed using the Chi-square test, and Kaplan-Meier method and Log-rank test were used for survival analysis. The independent prognostic factors of rNPC were analyzed by Cox regression model.</p><p><b>RESULTS</b>Low SDHB expression was showed in 76.5% (39/51) of the patients with rNPC, significantly higher than 57.1% (24/42) of primary nasopharyngeal carcinoma (χ(2) = 4.098, P < 0.05). Low expression of SDHB strongly was correlated with T classification, clinical stage and cranial nerve palsy. Patients with low SDHB expression had a shorter survival time and a lower 3 or 5 year survival rate compared to the patients with high SDHB expression. Multivariate analysis showed that low SDHB expression was an independent predictor for overall survival of patients with rNPC (P < 0.05).</p><p><b>CONCLUSION</b>The low SDHB expression is an independent indicator for poor prognosis of rNPC and may play an important role in the recurrence of rNPC.</p>

The effects of Xuebijing injection on ATPase of diaphragm in rats with acute organophosphorus poisoning / 中国中西医结合急救杂志

Objective To investigate the changes in ATPase activity of diaphragm in rats with acute organophosphorus poisoning (AOPP) and to explore the effect of Xuebijing injection on the ATPase activity. Methods 24 clean healthy Spraue-Dawley(SD)rats were divided into control group,model group and Xuebijing treatment group by means of random number table,with 8 rats in each group. AOPP model was established by intra-gastrical administration of 50 mg/kg oxide dimethoate. In Xuebijing treatment group,after oxide dimethoate administration,intraperitoneal injection of Xuebijing(10 mL/kg)was given at the same time,while in control group and model group,equal amount of normal saline(NS)was injected via the same route. The rats were sacrificed at 6 hours after model formation,and their diaphragms were taken sterilely. The activities of Na+-K+-ATPase and Ca2+-ATPsae of diaphragms were detected by enzyme linked immunosorbent assay(ELISA). The histopathological changes in diaphragms of rats were observed with light microscopy. Results 6 hours after intoxication,the diaphragm Na+-K+-ATPase activity of rats in model group was markedly lower than that in control group(mmol?h-1?g-1:5.22±0.74 vs. 9.98±0.37,P<0.01),while the Na+-K+-ATPase activity in Xuebijing treatment group(6.93±1.14) was markedly higher than that in model group(P<0.05). The diaphragm Ca2+-ATPase activity of rats in model group was markedly lower than that in control group(mmol?h-1?g-1:7.45±0.74 vs. 12.08±0.74,P<0.01),while the Ca2+-ATPase activity in Xuebijing treatment group(9.35±1.67)was obviously higher than that in model group(P<0.05)after intoxication for 6 hours. Light microscope observation indicated that there were swelling and necrosis in diaphragm in model group,while in Xuebijing treatment group no necrosis was found. Conclusion The diaphragm was degenerated and necrotic in AOPP rats,Xuebijing injection can lessen the injury in such rats,and the curative effect may be related to the improvement of the Na+-K+-ATPase and Ca2+-ATPsae activities of diaphragm.

Clinical analysis of neural invasion in pancreatic cancer / 中华胰腺病杂志

ObjectiveTo study the situation of neural invasion in pancreatic cancer and investigate its related clinical factors. Methods The neural invasion in 73 cases of pancreatic cancer patients was retrospective analysed. The correlation between neural invasion and clinicopathological parameters,and survival rate was investigated.Results In 73 cases of pancreatic cancer,neural invasion occurred in 38(52.1％) patients,among whom intra-pancreatic neural invasion rate was 15.8％ (n =6) ; and both intrapancreatic and external pancreatic plexus invasion rate was 84.2％ ( n =32).Neural invasion was not related with gender,age,and pathological type,degree of differentiation,tumor size and lymph node metastasis (P ＞ 0.05 ).But the presence of abdominal pain,vascular invasion,the expression of EGFR and VEGF in tumor tissue was significantly related with neural invasion (P ＜0.01 ).The median survival of patients in neural invasion group was 8 months,which were significantly shorter than that of in patients without neural invasion (13 months,x2 =4.69,P =0.030).Conclusions Neural invasion has a high incidence in pancreatic cancer,and it can cause obvious abdominal pain.And it is related with vascular invasion and the expression of EGFR and VEGF in tumor tissue.Neural invasion is one of the factors affecting the survival rate.
