Objective To investigate the cause,type,clinical manifestation,diagnosis and treatment of bile duct injury(BDI)during laparoscopic cholecystectomy(LC).Methods Data of 26 cases suffering from biliary injury during LC from 1997 to 2007 were retrospectively analyzed.Results Among 26 cases with BDI,5 cases suffered from type Ⅰ BDI,13 cases from typeⅡ,2 cases from typeⅢ,and 6 cases from type Ⅳ.Injuries were diagnosed as BDI intraoperatively in 3 cases,23 BDI cases were diagnosed postoperatively,including 13 cases diagnosed one week after LC,8 cases 20-60 days after LC,2 cases 2 years after LC.Twenty-four cases underwent interventional therapy,with 5 cases cured,19 cases were tideovered to operative treatment after cholangitis and jaundice were under control.Among all BDJ cases,20 cases underwent resection of impaired dile duct and hepatico-jejunostomy. Conclusion BDI is a serious complication of LC,temporary stent graft or bile dranage will help to put jaundice and cholangitis under control so as to buy a time for final definite surgical procedures.

Objective To investigate the value of interventional therapy in bile duct injury (BDI) due to laparoscopie cholecystectomy (LC). Methods Data of 24 BDI patients, who received interventional treatment after LC from June 1997 to May 2007, were retrospectively analyzed. Results According to Liu Yunyi criteria of BDI classification, there were 5 cases of type Ⅰ , 11 cases type Ⅱ , 2 type Ⅲ and 6 type Ⅳ. BDI was found during LC in 2 patients and the operation was switched to open cholecysteetomy, but bile duct infection was experienced 10 months and 2 years after the operation, respectively. BDI was diagnosed postoperatively in 22 patients, in which 13 eases occurred 3-12 days after LC, 7 cases 20-60 days after LC, and 2 cases 2 years after LC. Complete remission was achieved by interventional therapy in 5 patients, the other 19 patients received curative operation after control of cholangitis and jaundice. Among 13 patients who were diagnosed BDI 3-12 days after LC, 6 underwent emergency operation and failed. Of the 7 other patients who received interventional therapy, 3 were cured and the others underwent curative operation after cholangi-tis and jaundice were controlled. Conclusion Application of interventional therapy in BDI after LC can a-chieve successful bile duct support and drainage, and can obtain complete image of bile duct system, which is effective not only in control of cholangitis and jaundice for the safety of the following surgery, but also in cure of BDI.

Furthermore,the effects of OCT on tumor growth metastasis were investigated in nude mice with implanted HCC.The expression of cMet in implanted tumor cells was studied by immunohistochemistry.Results With OCT treatment,the proliferative ability of Bel7402 cells and cell morphology didn't change.The adhesive and invasive ability decreased compared with no OCT treatment cells(P

Objective To evaluate the effects of branched-chain amino acids-enriched early parenteral and enteral nutrition on the liver function and serum aminograms in cirrhotic rats after partial hepatectomy. Methods In this prospective randomized controlled study, 24 cirrhotic rats, induced by thioacetamide, were randomized into three groups: enteral nutrition (EN) group, EN + branched-chain amino acid (BCAA) group, and parenteral nutrition (PN) + BCAA group. After receiving partial hepatectomy, rats in all three groups were nutritionally supported with equal amount of calorie and nitrogen contents from the 1st postoperative day ( PO day 1 ) to PO day 5. On PO day 6, parameters including body weight, liver functions, prealbumin, transferring, and serum aminograms were measured or determined, and the level of liver albumin mRNA was detected by reversal transcription-polymerase chain reaction and morphological examinations such as HE staining and immunohistochemical staining, which were assessed by index of Ki67 protein index. Results Body weight was significantly decreased in all three groups on PO day 6 (P ＜0.05 ). Compared with EN + BCAA group, serum aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase after partial hepatectomy were significantly higher in PN + BCAA group (P ＜0.05 ). Serum alkaline phosphatase level was significantly higher in PN + BCAA group than in EN group ( P ＜0. 05). The level of prealbumin was significantly lower in PN + BCAA group when compared with EN group or EN +BCAA group ( both P ＜ 0. 05 ), although no such significant difference was noted in terms of transferrin ( P ＞0. 05 ). The levels of leucine and isoleucine elevated while those of tyrosine, phenylalanine, arginine and tryptophan declined in PN + BCAA group or EN + BCAA group when compared with EN group ( P ＜ 0. 05 ). Aminograms were not significantly different between EN + BCAA group and PN + BCAA group ( P ＞ 0. 05 ). Levels of total amino acid and aromatic amino acid (AAA) were significantly lower while BCAA and ratio between BCAA and AAA (BCAA/AAA) were significantly higher in PN + BCAA group or EN + BCAA group than in EN group (P ＜ 0. 05 ).Significantly lower level of albumin mRNA and index of Ki67 were observed in PN + BCAA group than in EN group or EN + BCAA group (P ＜ 0.05 ) on PO day 6. Conclusions BCAA-enriched EN or PN reverses amino acid disequilibrium and restores BCAA/AAA in cirrhotic rats after partial hepatectomy. Compared with PN, EN is superior in improving postoperative liver function, promoting protein synthesis, and speed up tissue regeneration in the postoperative liver. However, it still can not restore serum albumin in a short term.

Objective To determine the clinical significance of hepatocyte growth factor receptor (Met) and epidermal growth factor receptor (EGFR) in the clinicopathology and prognosis of pancreatic cancer.Methods 70 patients admitted with pancreatic cancer from 1995 to 2005 were retrospectively analyzed with clinicopathological and follow-up data.Expression of Met and EGFR in cancer nest embedded with paraffin were detected by immunohislostaining (EnVision method) and correlation with clinicopathologic parameters and mutual correlation between these two receptors were further analyzed.Prognosis and related risk factors were analyzed by Kaplan-Meier survival analysis and Cox regression analysis,respectively.Results Both Met and EGFR significantly correlated with TNM staging,tumor size and superior mesenteric vessels invasion (P＜0.05).Expression level of Met positively correlated with that of EGFR (r9 =0.658,P＜0.05).Both Met and EGFR significantly correlated with patients' survival (P＜0.05) and Met was an independent prognostic risk factor for pancreatic cancer.Conclusions Both Met and EGFR significantly affect development and prognosis of pancreatic cancer and correlate with each other.Simultaneously targeting both Met and EGFR pathways may provide an advisable strategy of targeted therapy in pancreatic cancer.

Five general practitioners were trained for application of the enhancing CalgaryCambridge guide in consultation.The consultation time in 50 patients were recorded before and after training and the satisfaction degree of patients was investigated by questionnaire survey.Results showed that the length of consultation time after training was longer than that before training (490 s vs 277 s,P ＜ 0.05) and also longer than that of specialists (490 s vs 268 s,P ＜0.05).The overall satisfaction rate of patients was increased after training (72％ vs 88％,P ＜0.05).The results indicate that training of Calgary-Cambridge guide for doctor-patient communication can improve the communication skills of general practitioners.

OBJECTIVE: To analyze the subjective and objective burden given by patients with mental disorder in a family, and probe into the family interference therapy model.METHODS: The method of looking up documentation was used to investigate the information about the family of patients with mental disorder. The study is to mainly investigate the burden status of Chinese family, observe the effect of social consensus on the family of the patients with mental disorder, detail explain and analyze the different burden and needs of the family of the patients with mental disorder in urban and rural area. Ant the same time, the family interference therapy model was introduced to apply in China.RESULTS: Objective family burden mainly includes economic burden and physical burden induced by earing for patients. Subjective burden are mainly mental crucifixion of the family member given by the patients with mental disorder; even severe mental injury. Social stigma can bring more serious subject burden to the Chinese family. Mental health services center reduces the depression of the family, and single-family session was used to further treat mental weakness and internal conflict of each family. The object to establish family support group was mainly to share the education and experience.CONCLUSION: Family members of the patients with mental disorder bear the subjective and objective burden. Family interference therapy can postpone the relapse of mental disorder, also improve the status of the patient in family and the harmonious degree of the whole family.

AIM: To observe the regulation of octreotide (OCT) on the expression of somatostatin receptor 2 (SSTR2) in Bel7402 hepatocellular carcinoma (HCC) cells, and the inhibition effect of OCT on the growth of HCC. METHODS: The effect of OCT on proliferative ability of Bel7402 cells was observed by MTT assay. The cell form was observed by light invert microscope. The adhesive and invasive ability was detected by cell adhesion and migration experiments. The cell cycle, SSTR2 expression of 7402 cells were determined by immunofluorescence flow cytometry. Nude mice bearing xenografts in situ were treated with OCT or saline control for 7 weeks since tumor implantation. The immunohistochemistry for SSTR2 was performed. SSTR2 mRNA expression in cell line and xenografts was measured by semi-quantitative RT-PCR. RESULTS: After OCT treatment, the proliferative ability and cell form of 7402 cells didn't change significantly. The adhesive and invasive ability decreased significantly. The ratio of cells in resting state (G 0/G 1) increased, but no apoptosis peak was observed. The SSTR2 expression on 7402 cell membranes decreased significantly. SSTR2 expression in cell line of OCT group was higher than control group, but there was no significant difference between them. The mean tumor weight in mice given OCT was significantly lower than that in control group. SSTR2 immunostaining in tumor cells of treatment group showed stronger positivity, compared with control group. SSTR2 mRNA expression in xenografts after OCT treatment was significantly higher than that in control group. CONCLUSIONS: OCT inhibits the growth of HCC through SSTR2. SSTR2 is regulated by its ligand, the long-term OCT treatment increases the SSTR2 expression and enhances the effect of inhibiting HCC, however, short-term treatment may induce its desensitization and the decrease in anti-tumor effect.

Objective To evaluate the impact of early enteral nutrition (EEN) compared with parenteral nutrition (PN) on patients after hepatectomy. Methods Seventy-eight patients undergoing liver resection were randomized prospectively into two groups: EEN group receiving early enteral nutrition (n=35) and PN group receiving parenteral nutrition (n=43). The patients in both groups received isocaloric and isonitrogenous nutritional formulas 24 h after operation and the formulas were stopped on postoperative day 7. The general conditions, liver function tests, clinical complications,and clinical nutritional variables at three time points that included preoperative phase, postoperative day 1 (POD 1) and postoperative day 8 (POD 8) were observed. Results No significant differences were found in length of hospital stay, liver function and clinical nutritional variables between the 2 groups. In the EEN group, the serum prealbumin level almost returned to the preoperative level on POD 8. The nutritional complication rate of the EEN group was increased significantly but it was milder than that of the PN group. The time of gut function recovery in the EEN group was shorter than that of the PN group. The costs of nutritional drugs showed a significant decrease in the EEN group.Conclusion Early enteral nutrition is safe, rational and effective in patients who have undergone hepatectomy. Early enteral nutrition is better than parenteral nutrition in promoting liver function recovery, liver protein synthesis, postoperative recovery of gut function and decreasing costs of nutritional drugs.

Objective: To analysis teratogenic effect of GDC-0449 to fetus and set up the animal model of GDC-0449 induced oromandibular limb hypogenesis in mouse for further research of its pathogenesis. Methods: Twenty-seven pregnant Institute of Cancer Research (ICR) mice were randomly divided into: control group, embryonic day 8.5 (E8.5) exposed groups, E9.5 exposed groups, E10.5 exposed groups, E11.5 exposed groups, E12.5 exposed groups, E13.5 exposed groups, E14.5 exposed groups and E15.5 exposed groups. Each group had 3 mice. Exposed groups were treated with the Hedgehog pathway antagonist GDC-0449 at a single dose 150 mg/kg by oral gavage from E8.5 to E15.5. At E16.5, embryonic phenotypes were analyzed in detail by stereo microscope and histology. After establish an optimal dysmorphogenic concentration, 6 pregnant ICR mice were randomly divided into control group and the optimal group, embryonic phenotypes were analyzed by whole-mount skeletal staining and micro-computed tomography at E18.5. Results: The mice were exposed to GDC-0449 on E11.5 and E12.5 had a high incidence of cleft palate. GDC-0449 exposed between E9.5 and E10.5 caused craniofacial and limb dysmorphology, including micrognathia, microglossia, ectrodactylia, partial anodontia and cleft palate. Most interestingly, these are extremely similar to oromandibular limb hypogenesis syndrome. Conclusions The results of this study indicate that GDC-0449 can be used to induce micrognathia, microglossia, ectrodactylia, partial anodontia and cleft palate. This work established a novel mouse model for oromandibular limb hypogenesis.
