OBJECTIVE: To explore the resource and solution of the expired drugs in citizen family through investigating its constituents and expired time.METHODS: By a random sampling,the records of the reclaimed drugs of a total of 1 000 cases collected from 6 drugstores were analyzed statistically.RESULTS: The main expired drugs reclaimed from citizen family were cardiovascular and cerebral vessels drugs,drugs for respiratory disease,and reinforcing and regulating drugs,and most of which were overdue 50 months ago.CONCLUSIONS: The situation of expired drugs in citizen family is serious,thus measures such as reclaiming expired drugs and popularizing knowledge about taking drugs should be taken to tackle the problem of expired drugs.

Objective To investigate the effects of hypoxia on the rheologic properties of leukocytes in microcirculation of rats, and its relationship with the expressive changes of CD18 of neutrophils. Methods Hypobaric chamber was used to simulate the plateau condition for the establishment of animal hypoxic model. Adult Wistar rats were randomized in three groups: control group, short-term hypoxia group (Hypobaric chamber simulated 5000m altitude for 3days) and long-term hypoxia group (Hypobaric chamber simulated 5000m altitude for 30 days). Intravital microscopy and computer image analysis system were used to evaluate the rheologic properties of leuckcytes in mesentery microcirculation. Neutrophils of the three experimental groups were purified and the expression of CD18 was determined by flow cytometer. Results Compared with control group, the rheologic properties of leukocytes were changed obviously at both short-term hypoxia and long-term hypoxia groups, including the number of leukocytes rolling and adherenced on endothelium increased, TLECT (total leukocyte-endothelium contact time) obviously extended (P

Objective To explore the effects of acute or chronic hypoxia on the viscoelastic properties of polymorphonuclear leukocyte (PMN) of rats. Methods Hypobaric chamber was used to simulate high altitude condition. Fifteen adult Wistar rats were randomized into 3 groups: control, acute hypoxia (5 000 m for 3 d) and chronic hypoxia (5 000 m for 30 d). Micropipette aspiration technique was used to evaluate the biomechanical properties of PMNs of rats and the experimental results were fitted with a three-element standard linear solid model. Results The viscoelastic coefficients of PMNs in acute hypoxic condition [K1=(86.66?26.84) Pa, K2=(399.89?22.03)Pa, ?=(4.23?1.82) Pa?s] or those values in chronic hypoxic condition [K1=(179.61?26.31) Pa, K2=(472.12?30.36) Pa, ?=(9.21?2.65) Pa?s] were significantly higher than the corresponding value of PMNs in control(P

0.05). It was a non-specific reaction to the rivanol. Conclutions The results indicate that cordocentesis is saft and reliable in clinical practice.

Objective To explore the relationship between the level of tumor necrosis factor related apoptosis inducing ligand(TRAIL) and death receptor 5(DR5) and atherosclerosis(AS).Methods Eighty-three patients were divided into two groups: Sixty-one in the coronary artery disease(CAD) group and 22 in normal coronary artery group.Plasma soluble TRAIL(sTRAIL) and soluble DR5(sDR5) levels from these people were assayed by ELISA.The level of TRAIL and DR5 protein expression in coronary arteries were detected by immunohistochemisty statining.Results Plasma sTRAIL and sDR5 significantly increased in the CAD group(P

OBJECTIVE To understand pathogen distribution and drug sensitive rate of urinary system infection in our hospital,in order to avoid the clinic to use antibiotics blindly,make the resistant strains decreasing in number,and improve efficacy.METHODS The distribution and drug sensitivity of the pathogens causing urinary infection among the patients with urinary system infection were rectrospectively analyzed.RESULTS Totally 549 strains were isolated,G-bacteria were 333 strains,accounted for 60.66%,from them E.coli was 293 strains,accounted for 87.99%;and G+bacteria were 216 strains,accounted for 39.34%,from them Enterococcus,and Staphylococcus were the main ones.Of E.coli strains,the ESBLs(+) were 36.86%.The MRCNS accounted for 81.91%.The result of drug sensitivity showed that the sensitive rate of E.coli to meropenem and imipenem was 100.0%.The sensitive rate of ESBLs(+) E.coli to cefepime,cefotaxime and aztreonam was all lower than 50%,but that of ESBLs(-) to the above drugs was much higher than ESBLs(+).The sensitive rate of Enterococcus to vancomycin and teicoplanin was 100%.The sensitive rate of CNS to Vancomycin was 100%.CONCLUSIONS In order to decrease the produceing bacteria resistance and the disseminating the resistance genes,it′s necessary to enhance the monitoring and study of bacteria resistance,normlalize the clinical medicine application,and enhance the infection control measures.

Objective To investigate the distribution and antibiotic resistance of A.baumannii during the last five years in our hospital,the basis for the reasonable clinical use of antibiotic was provided to doctor.Methods The strains of A.baumannii isolated from clinical specimens during 2009-2013 were analyzed by VITEK-32 system,the antibiotic resistance was analyzed by WHONET5.4 software.Results A.baumannii strains were mainly isolated from sputum,accounting for 77.3％;the majority of the strains were isolated from ICU,accounting for 42.3％;the resistance rates of A.baumannii to antibiotics appeared increasing,and over 70％ except cefoperazone-sulbactam and imipenem.Conclusion A.baumannii is the major pathogen,and detection rate of A.baumannii is very high,antibiotic resistance status of A.baumannii is very serious.The management of antibiotic application should be strengthened,and the occurrence and prevalence of antibiotic resistant bacteria should be strictly controlled to prevent outbreak and epidemic of nosocomial infection.

Objective To investigate the feasibility, effect and mechanism of chemical bile duct embolization for chemical hepatectomy. Methods Phenol or absolute ethanol plus cyanonacrylate were employed as embolization agents. Histology, Fas and TGF-? 1 measurement were used to evaluate the result. Results Phenol plus cyanonacrylate effectively destroyed and embolized intrahepatic biliary duct, leading to complete disappearance of hepatocytes in the periphery of embolization lobe and thereby achieving the effect of chemical hepatectomy. Expression of Fas and TGF-? 1 in phenol embolism group (88.90?38.10, 185.22?70.39) and ethanol embolism group (72.39?29.51, 163.56?51.75) were higher than those in biliary duct ligated group (26.31?12.07, 74.84?40.73) ( P

Objective To investigate the clinical value of galectin-3 expression on fine needle aspiration (FNA) smearsandtissueslicesof thyroid tumors in distinguishing benign from malignant tumors. Methods Galectin-3 expression on FNA smears and tissue slices of thyroid tumors from 72 thyroidectomy specimens was detected by immunochemical method (SP method). Results Galectin-3 expression was high on FNA smears and tissue slices of malignant thyroid tumors, whereas there was no or low expression of galectin-3 on FNA smears and tissue slices of benign thyroid tumors. The difference of positive rates of galectin-3 expression between malignant and benign thyroid tumors was significant on both FNA smears and tissue slices (? 2=43.73 and ? 2=48.16, respectively, both P0.05). Conclusion Galectin-3 expression is different between benign and malignant tumors. Galectin-3 expression level is higher in FNA smears and tissue slices of malignant thyroid neoplasms than that of benign ones, suggesting that galectin-3 is a reliable molecular marker in distinguishing benign from malignant thyroid tumors. Galectin-3 expression with immunochemical method may be used in diagnosing benign or malignant thyroid tumors.

Objective To evaluate the therapeutic effect of different types of biliary tract reconstruction on the post- resection of congenital choledochal cyst (CCC). Methods 106 cases of CCC undergoing resection of CCC with Roux-en-Y hepaticojejunostomy as biliary tract reconstruction were followed up and analysed. Results In this series, three kinds of biliary tract reconstruction were performed, including single Roux-en-Y hepaticojejunostomy in 48 cases, intussusceptive valve and rectangular valve lying on the jejunal segmental of Roux-en-Y hepaticojejunostomy in 37 and 21 cases, respectively. 61 cases were followed up for 4.82 years in average. None of them occurred anastomasis stricture. There were 4 cases with ascending cholangitis after primary operation: of them 3 after single Roux-en-Y hepaticojejunostomy; symptoms of 2 out of the 3 cases disappeared after reoperation to set up an intussusceptive valve plasty on the jejunal segmental of Roux-en-Y hepaticojejunostomy; another one was in rectangular valve group. Occasional abdominal pain tooke place in 8 patients, of them, 5 in single Roux-en-Y hepaticojejunostomy group, 2 and 1 in intussusceptive valve and rectangular valve groups, respectively. No patients suffered from ascending cholangitis in the intussusceptive valve plasty group. Conclusions The postoperative ascending cholangitis and anastomasis stricture can be prevented effectively, if a prophylactic intussusceptive valve on the jejunal segmental of Roux-en-Y hepaticojejunostomy is carried out after resection of CCC for biliary tract reconstruction. This procedure corresponds to the biliary tract physiology.
