Objective To assess the influence of full-thickness continuous suture method and layer interrupted suture method in emergency abdominal operation closure.Methods Two hundred and thirtyseven patients of emergency abdominal operation were divided into full-thickness continuous suture method group (145 cases) and layer interrupted suture method group (92 cases) according to the suture method.The rate of incision liquefaction and infection,time of incision suture were compared between the 2 groups,the patients with incision liquefaction and infection were given bacterial culture.Results The time of incision suture in full-thickness continuous suture method group was significantly shorter than that in layer interrupted suture method group [(18.37 ± 7.42) min vs.(25.92 ± 5.79) min],there was statistical difference (P ＜0.01).There were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing between the 2 groups (P ＞ 0.05).In full-thickness continuous suture method group,the rate of incision liquefaction and infection in median incision was significantly lower than that in rectus abdominis incision [18.58％ (21/113) vs.31.25％ (10/32)],the rate of incision primary healing was significantly higher than that in rectus abdominis incision [81.42％ (92/113) vs.68.75％ (22/32)],there were statistical differences (P ＜ 0.05).In layer interrupted suture method group,there were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing between median incision and rectus abdominis incision [33.33％ (23/69) vs.26.09％(6/23),66.67％ (46/69) vs.73.91％ (17/23),P ＞ 0.05].The rate of incision liquefaction and infection in median incision of full-thickness continuous suture method group was significantly lower than that in median incision of layer interrupted suture method group,and the rate of incision primary healing was significantly higher than that in median incision of layer interrupted suture method group,there were statistical differences (P ＜ 0.05).There were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing in rectus abdominis incision between the 2 groups (P ＞ 0.05).The bacterial culture result in patients with incision liquefaction and infection showed positive was in 26 cases,in full-thickness continuous suture method group was in 10 cases (6.90％,10/145),in layer interrupted suture method group was in 16 cases (17.39％,16/92),there was statistical difference (P ＜0.05).The mostly bacterial of infection was Escherichia coli.Conclusions The full-thickness continuous suture in median incision can shorten operative time and reduce the rate of incision liquefaction and infection in emergency abdominal operation.Suture technique has important impact on incision healing.

[Summary] Laparoscopic sleeve gastrectomy ( LSG) as a sole and definitive bariatric surgery has achieved well results in terms of decreasing the body mass index ( BMI ) and percentage of excess weight loss (%EWL ) , therefore reducing the obesity-related complications , but the mechanism remains unclear .As a restrictive surgical procedure , the most important mechanism of LSG might be the reduction of the volume of the stomach resulting in a limited food intake .Therefore, to achieve the best weight loss after surgery , measuring the gastric volume is an indispensable technology .Currently, gastric capacity measurement methods include imaging measurements and intraoperative direct measurement . Imaging methods include upper gastrointestinal radiography , CT three-dimensional reconstruction , MRI and radionuclide scanning , with each having its advantages and disadvantages .In this article, the measurement methods of gastric capacity before and after LSG were reviewed .

Objective　To explore the relationship between te lomerase activity and bile duct carcinoma and its significance in clinical diag nosis. Methods　Telomerase activities were examined in 23 cases of bile duct carcinoma, 5 cases of carcinoma adjacent tissues and 5 cases of nor mal bile duct tissues respectively with telomerase PCR-ELISA method. Results　Telomerase activity was detected in 18 of 23 cases (78.3%) of b ile duct carcinoma, and was not found in 5 cases of carcinoma adjacent tissues a nd 5 cases of normal bile duct tissues. The detection rate of telomerase activit y had no correlation with patients' age, sex, tumor site and size but significan tly correlated to metastasis of tumor (P<0.05). Conclusion　The level of telomerase activity was significantly higher in bile duct carcino ma and may be served as one of the clinical marker for malignant neoplasm becaus e of its spsecificity.

Objective To detect P0.1 and respiratory function of patients with cerebral infarction(CI)and analyze the effect of cerebral infarction on respiratory function. Methods Arterial blood gases, respiratory drive and lung function were measured in 35 cases with CI and 15 healthy controls. The figures were analyzed by SPSS 10.0. Results The PaO0.2 (mm Hg, 75.80±4.12, 1 mm Hg=0.133 kPa), SaO2(%,94.97±0.78) and Plmax(kPa,4.076±2.443) were lower than those in the healthy control group (88.68±3.77, 96.40±0.48 and 7.747±0.599,t=-8.310,-5.731,-5.439,all P=0.000). P0.1 max and P0.1/MV in the CI group were lower than those in the healthy control group;the P0.1 did not have significant difference in these two group; the P0.1/P0.1max and P0.1/Plmax in the CI group were significantly higher than those in the healthy control group; the PImax was correlated with PO2, O2sat, P(A-a) O2, P0.1max, P0.1, P0.1,/PImax, P0.1/P0.1max, FVC, FEV1.0 and PEF; the PEmax was correlated with P0.1/ PImax, FVC, FEV1.0 and PEF. Conclusion The respiratory function of patients with CI has been impaired, the oxygenated index is cut down and the respiratory drive and respiratory drive store are decreased.

The development and progression of tumors are closely related to the tumor microenvironment.As one of the most important com-ponents in tumor microenvironment,cancer-associated fibroblasts (CAFs)play an important role in carcinogenesis,angiogenesis,inva-sion,and metastasis of tumors.The role of CAFs in the development and progression of hepatocellular carcinoma (HCC)is reviewed by dis-cussing how CAFs are recruited and activated in the tumor microenvironment and how CAFs promote tumor angiogenesis and regulate tumor immunity.This review may provide new approaches for the treatment of HCC.

Objective To research the indoor air pollution in offices induced by decoration and its health effects. Methods According to the completed time, the offices were divided into 6 groups (2 month group, 2-4 month group, 5-8 month group, 9-11 month group, 12-18 month group, over 5 year group). The concentration of indoor air pollutants was determined and 617 people from the decorated offices were randomly selected to finish the questionnaires on health. Results The over standard rate of formaldehyde, benzene and ammonia in indoor air was the highest in 2 month group, 100%, 87.3%, 83.9% respectively. The concentration of indoor air pollutants decreased as the time went on, about one year after decoration, the concentrations were lower than the standard limits (GB/T 18883-2002). The adverse response rate of the staff members in offices decorated group (76.4%) was significantly higher than that in the control group (30.9%) (P

To evaluate whether different doses of X ray irradiation can induce apoptosis of rat C6 glioma cells. A rat C6 glioma cell was irradiated with X ray in different doses in vitro. Apoptosis was identified by the classical “ladder” pattern (oligonucleosome sized fragments) in DNA agarose gel electrophoresis. Results: The results showed that significant apoptosis was found in 15, 20 or 30 Gy groups at 4 hours and 1 day after X ray irradiation compared with control, whereas this phenomenon could only be seen vaguely in the 40 Gy group. The latter group showed more necrosis than apoptosis. It suggested that the apoptotic mode of cell death and necrosis may represent the response in this X ray irradiated rat C6 glioma cells in vitro.
