Objective To summarize the clinical experience of laparoscopic cholecystectomy (LC) in the treatment of acute cholecystitis. Methods A total of 93 cases of acute cholecystitis treated by LC from May 2003 to May 2005 was retrospectively reviewed, including 15 cases of preoperative endoscopic retrograde cholangiopancreatography (ERCP) combined with endoscopic sphincterotomy (EST) for common bile duct stones and 6 cases of intraoperative cholangiography. The LC was performed within 48 hours after admission. Results The LC was successfully completed in 91 cases (97.8%), whereas a conversion to open surgery was required in 2 cases (2.2%). The operation time was 35~160 min (mean, 65 min). Postoperatively, biliary leakage occurred in 3 cases (3.2%) and residual stones in the common bile duct were found in 3 cases (3.2%), which were all cured by open surgery combined with ERCP, EST, and endoscopic nasobiliary drainage (ENBD). No iatrogenic injuries happened. Conclusions With proper selection of ERCP and EST, LC for the treatment of acute cholecystitis is feasible and safe. But the incidence of conversions and complications may be high.

Objective This study aimed to investigate the effects of angiotensin Ⅱ and Losartan pretreatment on regulating insulin secretion in human islet ? cells.Methods We measured changes in intracellular calcium by confocal laser scanning microscopy using Flou3-AM-loaded human islet cells.RT-PCR was used to measure changes in intracellular CaM.Dynamic insulin secretory responses were determined by chemiluminescence following perfusion of human islets.Results Exposure of the isolated islets to angiotensin Ⅱ induced glucose-stimulated insulin release coupled with intracellular calcium ascending in first phase and descending in second phase.Intracellular CaM concentration could not be affected by angiotensin Ⅱ.Conclusion The change of free Ca2+is induced by the combination of AngⅡ with ATI receptors of islet B cells,which results in the damage to islet B cells.Losartan pretreatment protects the islet B-cell function by inhibiting calcium overload.

Objective To study action mechanism of rhamnocitrin in Oxytropis Falcata on enhance the immune function. Methods Kunming mice were randomly divided into blank control group, model group, positive control group, traditional Chinese medicine high, medium, and low dose groups. All treatment groups received gavage with relevant medicine for 10 days. From the 8th day, blank control group received intraperitoneal injection with normal saline, while other groups received intraperitoneal injection with cyclophosphamide for 3 days. Through macrophages carbon clearance test, macrophage phagocytosis of chicken erythrocytes test, and immunosuppressive mice organ index detection, effects of rhamnocitrin in Oxytropis Falcata on nonspecific immune function of immunosuppressive mice were observed. Results Compared with model group and blank control group, traditional Chinese medicine high, medium, and low dose groups could improve the phagocytic activity of immunosuppressive mice, clearance index, and phagocytic coefficient (P<0.05), and increase the organ index of the thymus and spleen. Compared with the positive control group, the efficacy of traditional Chinese medicine high, medium, and low dose groups was low. Conclusion Rhamnocitrin in Oxytropis Falcata can enhance the immune function, improve the formation of spleen cells of mice serum hemolysin of chicken red blood cell immune.

Objective To explore the value of early arterial blood lactate clearance rate and central venous oxygen saturation (ScvO2 ) monitoring in patients with severe pneumonia .Methods A total of 56 patients with severe pneumonia treated during the period from January 2012 to December 2013 were reviewed retrospectively .The arterial blood lactate concentration and ScvO2 were determined immediately after admission to hospital and 6 hours after admission to calculate the 6‐hour lactate clearance rate .APACHE II score was evaluated at the same time .The patients were divided into three groups according to APACHE II score:10 to <20 (group A) ,20 to <30 (group B) ,≥30 (group C) .The three groups were compared in terms of early arterial blood lactate clearance rate and ScvO2 and estimate their association with the prognosis of patients .Results The initial arterial blood lactate concentration did not show significant difference between the three groups (P>0 .05) .The early lactate clearance rate and ScvO2 at 6 hours in group C were significantly lower than in group B .The values in group B were significantly lower than in group A (P<0 .05) .The mortality rate in group C was significantly higher than in group B ,and the mortality rate in group B was significantly higher than in group A (P<0 .05) .The APACHE II score of the dead patients was higher than that of the suevivors ,but early lactate clearance rate and ScvO2 level were lower than those of the survivors (P<0 .05) .APACHE II score was negatively correlated to early lactate clearance rate (r=0 .661 ,P<0 .01) and early ScvO2 level (r=0 .579 , P< 0 .01) .Conclusions Early lactate clearance rate and ScvO2 level are good indicators to reflect the severity of disease and predict the outcome in the patients with severe pneumonia .

Objective:To compare the clinical efficacy of Du's heat-reinforcing method and Western medication in treating diarrhea-predominant irritable bowel syndrome (IBS-D).Methods:Sixty-five IBS-D patients were randomized into two groups by the random number table.Thirty-three cases in the treatment group were intervened by acupuncture with Du's heat-reinforcing method,while thirty-two cases in the control group were given oral administration of pinaverium bromide tablets.The intervention lasted 4 weeks for both groups.The IBS symptom severity score (IBS-SSS),IBS-quality of life (IBS-QOL) and hospital anxiety and depression scale (HAD) were adopted to evaluate the therapeutic efficacy.Results:The two groups each had two dropout cases.The clinical recovery rate was 38.7% and the total effective rate was 90.3% in the treatment group versus 13.3% and 66.7% in the control group.The treatment group was superior to the control group in both clinical recovery rate and total effective rate (both P<0.05).After 1-week and 4-week treatment,respectively,the IBS-SSS scores were lower compared with the baseline in both groups,and the intra-group differences were statistically significant (both P<0.05);the score in the treatment group was lower than that in the control group,and the between-group difference was statistically significant (both P<0.05).After 4-week treatment,the component scores of IBS-QOL showed improvements in both groups,and the treatment group was superior to the control group in the improvements of dysphoria,interference with activity,health worry and food avoidance (all P<0.05).The anxiety and depression scales of HAD (HAD-a,HAD-d) in the treatment group and the HAD-a in the control group obtained significant improvements (all P<0.05);the scores of HAD-a and HAD-d in the treatment group were significantly better than those in the control group (both P<0.05).Conclusion:Acupuncture with Du's heat-reinforcing method can effectively ease the symptoms of IBS-D,improve the quality of life and the state of anxiety and depression.It can produce a more significant efficacy than oral administration of pinaverium bromide tablets.

Chlorella pyrenoidosa No.2 was screened from five species of microalga Chlorella sp. for its higher lipid yield. Effects of medium components and culture conditions on cell growth as well as lipid ac-cumulation of C. pyrenoidosa No.2 were investigated and the results showed that the optimum medium rec-ipe was 20.0 g/L glucose,0.08 g/L glycine,1.0 g/L K2HPO4?3H2O,0.4 g/L MgSO4?7H2O and 0.004 g/L FeSO4?7H2O. The optimum culture temperature,initial pH,shaking rate and light intensity were 28℃,6.0,130 r/min and 650 Lux,respectively. Biomass and lipid content increased from 3.73 g/L and 40.15% to 6.56 g/L and 59.90% when Chlorella pyrenoidosa No.2 was cultivated under the above optimal conditions for 7 days,with lipid yield raised by 162%. Chlorella pyrenoidosa No.2 could produce lipid with xylose as carbon source,and so is potential for lipid production from renewable materials such as lignocellulose. GC analysis demonstrated that the fatty acid composition of the lipid was similar to that of vegetable oil and its unsaturated fatty acid content reached around 71%,thus it is a promising material for biodiesel production.
