OBJECTIVE To investigate pathogenic bacteria and prognosis of abdominal infection and take measures to prevent and control it.METHODS We analyzed the clinical material and prognosis of 31 patients with abdominal infection retrospectively according to the culture results of puncture and drain liquid from abdominal cavity from Nov 2007 to Nov 2008.RESULTS In 31 patients,5 were complicated with pulmonary infectionwhich the infection rate was 16.13%,and 7(22.58%) died.Totally 48 pathogenic strains were isolated from ascitic fluid culture,20 strains(41.67%) were Escherichia coli,11 strains(22.92%) were Enterococus.Some of coagulase-negative Staphylococcus,Streptococcus,Candida,Klebsiella pneumoniae,and Staphylococcus aureus were also isolated.The resistance rates of E.coli to cephalosporins were above 50.00%,to quinolones were above 65.00%.The susceptibility rates of E.coli to some ?-lactamases inhibitors and carbapenem were very high.The resistance rate of Enterococus to rifampicin was 63.64%,to piperacillin/tazobactam and piperacillin was 81.82%,to erythromycin was 100.00%.The susceptibility rates of Enterococus to teicoplanin,vancomycin,and linezolid were 100.00%.CONCLUSIONS The predominant pathogenic bacteria of abdominal infection are E.coli and Enterococcus.Abdominal infection tends to combine with pulmonary infection.The patients who got into multiple organ dysfunction syndrome have high mortality.

Fever in patients with severe craniocerebral injury was a frequent occurrence.The rate of fever patients lead to plant man or death high up to 28％-72％.The univariate analysis found that there was significant association between fever and motality.One of the common cause of fever was non-infectious fever,which related with craniocerebral injury,including central fever,dehydration fever,clonus and rebleading fever.The major complication was central high fever after servere craniocerebral injury.The temperature high up to 39 ℃,which aggravated the original basic diseases,lead to respiratory and circulatory failure.Another cause of fever was infection fever which associated with nosocomial infection.Serious disease,long hospiltal stay,high proportion of invasive operation,coma were the high risk factors of patients with craniocerebral injury.The major type of nosocomial infection were pudmonary infection and surgical site infection.By reviewing domestic and foreign literatures and expert consensus,this article was intended to explore the characteristics and mechanism of fever in patients with craniocerebral injury.In order to reduce the secondary brain injury,decrease the disability rate,increase the sutrvival rate,diagnosis and treatment should be taken early.

Objective: To study the possibility of liposomes to ta rget hepatocytes af ter being linked with asialofetuin(AF). Methods: The biodistribu tions in differen t cells in liver as well as in blood, in various organs such as heart, spleen, l ung and kidney of mice, of traditional sterically stabilized liposomes(SSL) , AF-linked normal liposomes(AF-NL) and AF-linked sterically stabilized lipos ome s(AF-SSL) were studied by radioisotopic labeling. Results: The half-live s of SSL, AF-NL and AF-SSL were 14.44, 4.73 and 11.49 h， respectively. The di strib ution of liposomes in liver was AF-NL>AF-SSL>SSL. There was significant differenc e among these three formulations. In hepatocytes and non-hepatocytes, the conce ntr ations of the liposomes were both in line with the sequence AF-NL>AF-SSL>SSL( P <0.05). However, the ra tios of the concentrations in hepatocytes to that of non-hepatocytes were AF-N L≈AF -SSLSSL( P <0.05). Conclusion: After being labeled with asi alofetuin, liposomes can target hepatocytes very we ll， whether in long-circulation or not.

OBJECTIVE To enhance the healing rate of the wounded victims in earthquake and to do a good job on the nosocomial infection prevention and control according to the feature of the victims. METHODS The advance medical team on the train evaluated thd traumatic condition of the victims and sorted them according to their condition,then the victims with raw surface infection and that with no wound were arranged to the different sections and wards.The cleaning and medical inspection procedure for the victims were formulated.The secretions of their open wound surface with bacterial,fungal and anaerobic culturing at the very beginning were taken when their traumatic condition were examined.The management of wards,attendants and visitors were strengthened,the hand hygiene compliance and the right way to disposal clinical waste the disinfection and sterilization were supervised and directed. RESULTS Most of the 76 victims were with limbs injury,of which 14 victims with open injury,10 got bacterial or fungal infection.The infection rate was 71.43%.Most of them had got combined infection.No Clostridium tetani and C.perfringens were isolated from the secretion of the raw surface.Three victims were complicated with urinary system infection,1 with pulmonary infection and 1 with bed-sore infection after wounded in earthquake.Basing on effective debridement and change dressings,the antibacterial agents were applied according to pathogenic bacteria and the antimicrobial susceptibility test,so the wound surface and general infection were controled effectivelly.Another 35 victims with closed fracture who were operated with internal fixation and reposition after discection in the limited time were not infected. CONCLUSIONS The infection rate of raw surface of victims with open injury is high.Most of the wound surface are infected with some multidrug resistant bacterial and fungi and combined with urinary system infection or pulmonary infection.The nosocomial infections precaution and control should be strengthened to prevent cross infection when treating the victims wounded in earthquake.

Objective:To discuss strategies in treatment of poorly differentiated thyroid carcinoma (PDTC) .Methods:Clinical data of 31 cases with PDTC were reviewed retrospectively, who were treated in Department of Head & Neck Surgery, Sichuan Cancer Hospital & Institute by primary surgical resection with or without adjuvant therapy. 27 cases had total thyroidectomy compounded neck dissection or extened total thyroidectomy when trachea or esophagus involved. 4 cases underwent partial resection of tumor. 11 cases were treated with external beam radiotherapy (EBRT) after surgery, 10 cases were treated with postoperative radioiodine, and 8 cases had chemotherapy.Results:The median follow-up time was 18 months (ranged from 3-96 months) . 19 patients died of local recurrence or distant metastasis. Kaplan-Meier analysis and Log-rank analysis was used to compare the differences between groups. Five-year survival was 35.9%. Compared to the cases with partial resection, the cases with surgical disease clearance had longer survival ( P=0.00) . The same statistical difference was found between patients with or without radioiodine ( P=0.017) . The patients treated with radioiodine had longer survival. No statistical differences were found among patients with or without chemotherapy or EBRT. COX regression analysis showed stage of tumor ( P=0.005) , total resection ( P=0.006) and postoperative radioiodine ( P=0.013) were same to predict longer survival. Conclusions:Thorough resection of tumor is the most important therapy for PDTC. Postoperative radioiodine is recommended for patients with high recurrence risk. EBRT is recommended to control local unresectable PDTC.

Nonalcoholic fatty liver (NAFLD) is a substantial pathological change of the liver caused by no excessive alcohol intake or genetic predisposition. It can further develop into non-alcoholic steatohepatitis, liver cirrhosis, hepatocellular carcinoma, liver failure. Studies have shown that non-alcoholic fatty liver is also closely related to a variety of metabolic diseases, such as type 2 diabetes mellitus(T2DM), hypertension, cardiovascular disease and so on. However, its pathogenesis is not clear, and there is a lack of drugs for clinical treatment. Ginsenoside Rg1 has a wide range of effects, such as antioxidation, anti-aging, anti-inflammatory reaction, auxiliary treatment of diabetes and so on. In this paper, the pathogenesis of NAFLD and the research progress of Rg1 in NAFLD are reviewed.
