AIM:To study the main chemical components of traditional Tibetan medicine Pazhu Capsule(Calcitum,Fructus Chebulae,Semen Granati,Fructus Piperis,Fructus Piperis Longi,etc.) in the treatment of gastropathy. METHODS: The soluble components of Pazhu Capsule were extracted by supercritical-CO_2 fluid.The components were measured by GC-MS and the relative amount of them were determined by peak area normalization.(RESULTS:)22 components were identified.The main components were piperine(44.2%),9,12-Octadecadienoic acid(z,z)(21.1%),Azuleno[45-b] furan-2(3H)-one,3a,4,6a,7,8,9,9a,9b-octahydro-6-methyl-3,9-bis(methylene)-,[3as-(3a.alpha.,9a.alpha.,9b.beta.)](10.55%),n-Hexadecanoic acid(4.8%) and 2(3H)-Benzofuranone,6-ethenylhexahydro-6-methyl(33.5%).CONCLUSION: The main components of the Tibetan medicine Pazhu Capsule are piperine and 9,12-Ocatadecadienoic acid,both contents are up to 65.3% of the total extracts.

Objective To evaluate the timing,feasibility and necessity of early laparoscopic cholecystectomy (LC) in management of patients with mild to moderate acute pancreatitis with gallbladder stones.Methods The clinical data of 75 patients with mild to moderate acute pancreatitis and gallbladder stones treated from September 2010 to August 2014 in our hospital were analyzed retrospectively.32 patients underwent LC within 48 hours of the pancreatic attack.The results were compared with those from 43 patients with delayed LC.Results All the patients were operated by experienced surgeons.There were no significant differences between the two groups in operation time,postoperative complications,intraoperative blood loss,conversion rates,white blood cell count,percentage of neutrophils and blood amylase before and after the operation (P ＞0.05).Patients who received delayed LC had longer hospital stay [(10.6 ± 1.3) vs (17.1 ± 1.8),P ＜ 0.05].The readmission rate in patients with delayed LC was 30.2％ (13/43),and most admissions occurred within 2 ～4 weeks of hospital discharge.In patients with early LC,one patient developed necrotic pancreatitis and died of septic shock.All the remaining patients were cured.Conclusions It is safe,feasible and necessary to perform LC within 48 h in patients with mild to moderate acute pancreatitis and gallbladder stones.Such patients have a high readmission rate and the best timing of delayed LC is within 2 ～ 4 weeks after discharge from hospital.

Hepatocellular carcinoma (HCC) development is closely related to overexpression of tumor promoters or down-regulation of tumor suppressors.The mammalian sirtuin family was found to be a nicotinamide adenosine dinucleotide (NAD/NADH)-dependent histone deacetylase (HDAC),which implicated in the regulation of critical biological processes through deacetylation modifying on histone and nonhistone.SIRT1 can regulate metabolism,aging,inflammation and cancer progression.In particular,more and more evidence proves that SIRT1 can act as a tumor promot er in hepatocellular carcinoma through deacetylation on tumor suppressors.On the other hand,SIRT1 can strongly suppress metabolic syndrome-associated liver cancer in the mouse model.This review will discuss the expression of sirtuin family member in liver cancer and its clinical significance.

92 specimens from patients with invasive ductal carcinoma were investigated. The expression of vascular endothelial growth factor (VEGF) was demonstrated by immunocytochemical staining with an antibody against VEGF and was quantitatively estimated by using computerized image analysis system. Vessels were immunohistochemically highlighted by using an antibody to CD34, and microvessel density (MVD) was quantified. The postoperative survey in univariate analysis showed that the relapse-free-survival (RFS) time of patients with more than 87 microvessels in single microscopic field was significantly worse compared to that of patients with less than 87 microvessels in node-negative patients (P<0.05). Multivariate analysis confirmed that MVD was an independent prognostic indicator for RFS in node-negative patients and all patients (P<0.05～0.01). In addition, there was a closely positive correlation between VEGF and MVD (P<0.01). The results suggested that VEGF plays crucial roles in the promotion of angiogenesis in primary breast carcinoma. VEGF and MVD are closely correlated with biological behavior of primary breast carcinomas. MVD can provide a useful message in predicting the recurrence or metastasis of tumors.

Objective To investigate the changes of plasma IL-6 and IL-8 level and the inhibitory effects of preoperative administraction of bile salt or anti-endotoxin antibody against endotoxin in cases of obstructuve jaundice.Methods 50 cases with obstructive jaundice were randomized into OJT1 group taking bile salt orally,OJT2 group receiving intravenous anti-endotoxin antibody and OJ group receiving general treatment.The plasma levels of endotoxin(ET),interleukin-6(IL-6) and interleukin-8(IL-8) were determined in all the cases.Results The plasma ET level was significantly lower in the patients of OJT1 and OJT2 groups than in those of OJ group preoperatively and was further decreased postoperatively(P

We report the results of nephrectomy under laparoscopy for 3 patients. Three patients were subjected to laparoscopy for the treatment of hydronephrosis of no function under general aneshesia. Succesiful operation was performed in the 3 patients without complication, the average operation time being 240 minutes, and hospitelization duration averaging 4.5 days.

Objective To establish an efficient, effective hepatocyte isolation technique in order to increase cell production and decrease the prime cost. Methods The inferior vena cava below diaphragm was dissected and ligatured, and the inferior vena cava below liver was separated. Subsequently, the liver was perfused with EGTA through the portal vein while the inferior vena cava below liver was opened, and then the liver was harvested. The liver tissue was cut into 1 mm?1 mm?1 mm and digested at 37 ℃ water bath with Ⅳ collagenase for 30-40 minutes, then the hepatocytes were purified and cultured in CO 2 incubator. The production and function of hepatocytes were assessed. Results The isolated hepatocytes using this technique were more than 95% among the all isolated cells. No statistic difference was found in cell production and cell function comparing with traditional technique. But this technique was simplified and more economically. Conclusion This modified hepatocyte isolation technique is efficient and effective. It can ensure the amount of production and purity of hepatocytes.

OBJECTIVE: To study the characteristics and regularity of adverse drug reactions (ADR) occurred in our hospital. METHODS: A total of 241 ADR cases occurred in our hospital form Jan. 2006 to Jun. 2009 were analyzed statistically in respect of patients’ status, category of drug, route of administration, organs and system involved in ADR and clinical manifestations. RESULTS: Of the total 241 ADR cases, 69.71%ADR cases were induced by antibacterials. 71.78% ADR cases were induced via intravenous administration. ADR mainly appeared as lesion of skin and appendants (50.92%). CONCLUSION: It is necessary to intervene and guide clinical use of drug, strengthen the monitoring of ADR and reduce the occurrences of ADR.
