OBJECTIVE To explore the status of nosocomial infection,infection sites of patients and susceptible factors of infection in neuro-intensive care unit(NICU) in order to correspondently prevent and control the occurrence of nosocomial infection.METHODS The clinical data of 471 patients admitted to NICU from Mar 2005 to Feb 2006 were investigated retrospectively.RESULTS Out of 471 cases in one year,a total of 90 cases of nosocomial infection were found.The rate of nosocomial infection was 19.11%.Among the nosocomial infection sites,the respiratory tract was the most frequent one(46.67%).The second was urinary tract(44.17%).The patients aged of more than 60 years,or with urethral catheter,mechanical ventilation,vein intubations,or with long medical intubation suffered infection more susceptibly than other patients.The infection rate of nosocomial infection was significantly different from hospitalization group.Sex was not evidently related to nosocomial infection.CONCLUSIONS The rate of nosocomial infection in NICU is largely higher than the total rate of infection.The susceptible factors are age,long-term hospitalization,invasive operations and long medical intubation.

Traditional Chinese medicine (TCM) is a very practical subject, which has its unique theoretical system and clinical characteristics. In the course of clinical practice, the exact clinical efficacy is the key of existence and development. But the existing evaluation system is difficult to objectively evaluate the clinical efficacy of TCM. Therefore, how to objectively evaluate the clinical efficacy and get definitive evidence is the focus of the evaluation of clinical efficacy of TCM. Relative to modern medicine, TCM is more concerned about the changes of feelings and clinical symptoms of the patient in the course of the evolution of the disease. Soft targets mainly used for the evaluation of the clinical efficacy of symptoms and functional activity of the disease. The level in soft targets of processing technology is often used methods in clinical evaluation. But it has often produced the phenomenon which the results of the evaluation is mutual contradiction, which will ultimately affect the effect of evaluation of clinical efficacy of TCM. In order to better evaluate the clinical efficacy of TCM, in the process of adoption of soft targets, it clearly identify it's role, highlighting the characteristics of interventions on disease, and as much as possibly avoid the level in soft targets of processing technology to real assess clinical efficacy of TCM.

Objective To study blood lipids levels of patients with ischemic cerebral vascular disease (ICVD).Methods The blood lipids levels were measured in 2886 subjects with ICVD enrolled from 1991 to 2004,in which 1430 subjects from 2000 to 2004 were classified into a sub-group;400 healthy persons receiving physical examination were enrolled as controls.Results The blood TC,TG and LDL-C levels were significantly higher in the sub-group than those in the control group.Both in males and females, the morbidity of abnormal blood lipid metabolism and blood lipids level gradually increased with the age and the lapse of decades.Total cholesterol level of male younger than fifty,averaging (4.43?0.51) mmol/L, increased to (4.96?0.85) mmol/L after fifty years old.The same thing happened to females,from (4.30?0.49) mmol/L to (5.01?0.90) mmol/L.TG and LDL-C increased in patients older than fifty compared with those younger than fifty.In the groups above 50 years old,the blood lipids levels of females were significantly higher than those of males.The morbidity of abnormal blood lipid metabolism of male increased from 24.5% in (1991 to 1994) to 38.1% (2001 to 2004) and of female from 22.3% (1991 to 1994) to 38.5% (2001 to 2004).Conclusions Abnormal blood lipid in Foshan is one of the most important reasons to ICVD.

The study aims to evaluate the bioequivalence of valsartan hydrochlorothiazide tablets, and to investigate the potential cause of bioinequivalence. This was a single-center study with an open, randomized double-way crossover design. Test and reference preparations containing 160 mg of valsartan and 25 mg of hydrochlorothiazide were given to 36 healthy male volunteers. Plasma concentrations of valsartan and hydrochlorothiazide were determined simultaneously by LC-MS/MS. The pharmacokinetic parameters and relative bioavailability were calculated, while the bioequivalence between test and reference preparations were evaluated. The dissolution profiles of test and reference preparations in four different mediums were determined via dissolution test and HPLC. The similarity was investigated according to the similarity factors (f2). The F(o-t) and F(0-infinity) were (139.4 +/- 65.2)% and (137.5 +/- 61.2)% for valsartan of test preparations. It led to get the conclusion that test and reference preparations were not bioequivalent for valsartan. A significant difference was observed between test and reference tablets in the valsartan dissolution test of pH 1.2 hydrochloric acid solution. The key factor of the bioinequivalence might be that dissolution of valsartan in acid medium has marked difference between two preparations.

Objective To evaluate hepatic artery resection and microsurgical reconstruction in radical resection of Klatskin's tumor.Methods We retrospectively reviewed clinical data of 7 patients with advanced hilar cholangiocarcinoma (Klatskin's tumor) who underwent left hemihepatectomy combined with right hepatic artery resection and microsurgical reconstruction with or without portal vein reconstruction from August 2008 to March 2012.Results Right hepatic artery was reconstructed with end-to-end anastomosis,using the reserved left hepatic artery (n =1),the remanent right hepatic artery (n =1),the hepatic artery proper (n =4) and the gastroduodenal artery (n =1),among those 2 patients underwent concomitant portal vein reconstruction.Post-operative pathology showed middle to low differentiated adenocarcinoma in 2 patients,low differentiated adenocarcinoma in 3 and papillary adenocarcinoma in 2.R0 resection was achieved in 6 patients.There was no post-operative liver failure,biliary-enteric anastomotic leakage or perioperative deaths.Conclusions Hepatic artery resection and microsurgical reconstruction increases the radical resection rate of advanced hilar cholangiocarcinoma and decreases postoperative complications.
