ObjectiveTo analysis the different types of bacteria in patients with a varying severity of acute cholangitis.Methods241 patients who presented with actue cholangitis between Jan 2008 to Oct 2011 to our hospital were retrospectively studied.These patients were divided into three groups according to the Tokyo Guideline.The bile specimens were obtained intraoperatively.The parameters were compared by SPSS 16.0 package program for statistical analysis.Results75.1 percent of the patients were positive for bacteria in the bile.There were 241 strains of bacterium which included 139 Gram-positive bacteria,99 Gram-negative bacteria and 6 strains of microzyme.Escherichia coli,Enterococcus faecalis,Enterococcus casseliflavus,Pseudomonas aeruginosa and Klebsiella species were the most frequently isolated bacteria.The positive rates for bacteria were significantly different between patients with mild and severe cholangitis (P＜0.05).There was no significant difference between patients with moderate and mild cholangits (P=0.141),or moderate and severe cholangitis (P=0.647).Gram-negative bacteria were more common than Gram- positive bacteria in patients with moderate and severe acute cholangitis (P＜0.05).In patients with moderate and severe acute cholangitis,there was more patients with multiple and mixed bacterial infection.ConclusionsEscherichia coli and Enterococcus species were more common in patients with acute cholangitis.The positive rate of bacteria in the bile in severe acute cholangitis was higher than that in mild acute cholangitis.In patients with moderate and severe cholangitis,Gram-negative bacterial infections and multiple and mixed bacterial infections were more common.

Objective To study the clinical efficacy of splenectomy plus porta-azygous devascularization in the treatment of portal hypertension using either the hand-assisted laparascopic (HALS) or the laparoscopic approaches.Methods The clinical data of 30 cases of portal hypertension treated between January 2008 and June 2012 were enrolled in this study.16 patients underwent HALS and 14 patients underwent traditional laparoscopy approach.Results All the operations were successfully accomplished.The mean operation time of the HALS group was significantly shorter than the traditional laparoscopic group (270 min vs 350 min,P＜0.05).Intra-operative blood loss of the HALS group was significantly less than the traditional laparoscopic group (250 ml vs 370 ml,P＜0.05).The median overall costs were significantly lower in the HALS group (30000 RMB vs 35000 RMB,P＜0.05).There were no significant differences in the time to return to oral diet,the length of hospital stay,and the time to passage of flatus.The complication rates between the two groups were similar.Conclusion Hand-assisted laparoscopic surgery had the advantages over conventional laparoscopic surgery in minimal invasiveness,safety,and quicker postoperative recovery.

Objective To compare the effects between percutaneous transhepatic gallbladder drainage (PTGD) plus delayed laparoscopic cholecystectomy (LC) in comparison with emergency LC for elderly patients with acute cholecystitis.Methods From June 2011 to December 2014,the clinical data of elderly patients with acute cholecystitis receiving PTGD plus LC and emergency LC were retrospectively studied.Results In this study 38 patients received PTGD plus LC,59 patients received emergency LC.Patients in PTGD + LC group had longer operative time (67 ± 14) min and higher conversion rate (5 cases)than those in LC group (51 ± 13) min,1 case (t =5.741,x2 =5.057,P ＜ 0.05),but had quicker bowel function recovery time (24.5 ±6.4) h,shorter hospital stay (4.2 ± 1.8) d,less complications (3 cases)than those inLC group (27±5.2) h,(6.2±1.9) d,17 cases (t =2.11,t=5.165,x2 =6.18,P＜0.05).Conclusions Percutaneous transhepatic gallbladder drainage plus delayed cholecystectomy is safe for elderly patients with acute cholecystitis.

Objective To study the expression of P57kip2 and its clinical significance in hilar bile duct adenocarcinoma.Methods The expressions of P57kip2 in hilar bile duct adenocarcinoma tissues (37 cases) and normal bile duct tissues (32 cases) were determined by immunohistochemical SP methods.The relations between the expression levels of P57kip2 with clinicopathologic parameters were analyzed.Results The positive rate of P57kip2 was 43.2％ (16/37) in bile duct adenocarcinoma,while it was 87.5％ (28/32) in normal duct tissues (P ＜0.01).The expression level of P57kip2 in adenocarcinoma showed no significant association with gender,age or CA19-9 level (P ＞0.05),but they were significantly related with lymph node metastasis,invasion and degree of differentiation (P ＜ 0.05).Conclusions P57kip2 is associated with the occurrence and development of hilar bile duct adenocarcinoma.It may play an important role in invasion and metastasis of hilar bile duct adenocarcinoma.The P57 protein can be used as an index to diagnose hilar bile duct adenocarcinoma.

Objective:To observe the effect of Gemcitabine ( GEM) on the viability and apoptosis of non-small cell lung cancer HCC827 in vitro. Methods:The cell viability,apoptosis and cell cycle of HCC827 cells induced by Gemcitabine were detected with cell counting kit-8 assay (CCK-8),Annexin V-FITC/PI staining and flow cytometry. The expression of Bcl-2 protein of cells treated with GEM was examined by Western blot assay. Results: There was significant inhibition effect on HCC827 cells treated with 0. 1-1 000 ng/ml of GEM,which can promote the occurrence of HCC827 cell apoptosis and arrest cell in the S phrase. The apoptosis induced by GEM was accompanied with the down regulation of Bcl-2 protein. Conclusion: GEM can inhibit the cell viability and induce the HCC827 cell apoptosis and S phrase arrest. Its cell dead type was apoptosis,which was related with the expression of Bcl-2 protein.

METHODS To study the incidence,pathogenic microorganism,prophylaxis,treatments of infectious complications in 150 patients accepted hematopoietic stem cell transplantation from April 1984 to March 1998 in our hospital.The results were analyzed statistically.RESULTS Incidence of infectious complications was 89.3% in all 150 cases.Three patients(2%) died of the fungal infection.The incidence of the infections was 32.5% in patients accepted treatment with imipenem or／and ceftazidine,and 15.7% in other patients without the treatment with imipenem or／and ceftazidine(P＜0.02).CONCLUSIONS The strong antibacterial prophylaxis can′t reduce the incidence of infection,and may increase the chance of fungal infection.

Objective To investigate the effects of extended care on the treatment compliance and the quality of life on discharged elderly patients with chronic heart failure. Methods One hundred and eight patients were randomly assigned to the experimental group and the control group with 54 patients in each, the experimental group received extended care for 1 year, including regular telephone and visit follow-up, supporting medical care, diet care, rehabilitation exercises and supervision of self-care. The control group underwent routine health education before discharge. Medical compliance and self-management ability were compared three months, six months and 1 year after discharge, evaluation score of life quality were also compared at discharge and one year after discharge between the two groups. Results There were no significant differences in medication, diet and regular follow-up visits between the two groups. However, the patients in the experimental group showed better compliance than the control group in the self-testing of urine, body weight,and recording of symptoms, body signs and required exercises. Additionally, the patients in the experimental group had higher scores than the control group in the daily life-skills, happiness and the quality of life. Conclusions The extended care significantly improved the treatment compliance and the quality of life in the elderly patients with chronic heart failure.

Objective To retrospectively evaluate the incidence and treatment of fungous infection compli-cations after hematopoietic stem cell transplantation. Methods The incidence, pathogenic microorganism, prophy-laxis,treatments of infectious complications in 150 patients, who accepted hematopoietic stem cell transplantation from September 1990 to Martch 2000 in our hospital were analyzed. Results The incidence of infectious complica-tions was 89.3% (134/150) in all 150 cases. Three patients (2%) died of the fungal infection. The incidence of the fungal infections was 32.5% (26/80) in patients who accepted treatment with impenem or/and ceftazidine, and 15.7% (11/70) in other patients without the above treatment (P<0.05). 12 fungal infection cases were treated with small-dosage of amphotericin B(10 mg/d) ,with the healing rate was 100%. Conclusion The strong antibac-terial prophylaxis can't reduce the incidence of infection ,but may increase the risk of fungal infection;small-dosage of amphotericin B is a new effective way to treat fungal infection.
