Objective:To investigate the adverse drug reactions ( ADR) caused by carbapenem antibiotics and discuss the influen-cing factors to provide reference for the rational use of carbapenems in clinics. Methods:The ADR caused by carbapenems from March 1, 2008 to August 1, 2014 in our hospital were statistically analyzed. Results:Totally 73 cases of ADR were caused by carbapenems. The number of ADR for men and women was similar. The ADR occurred in 80-year-old people with more frequency. The incidence of ADR on the first day of administration was relative high. The ADR were mainly manifested as skin and appendages disorders and nerve system damage. Conclusion: Great attention should be paid to the ADR of carbapenems and the state of patients. The medication should be adjusted in the patients with declined renal function and nerve system basic diseases in order to reduce the damage of ADR.

Objective To explore the correlation between the strength of trunk flexors and extensors obtained by isometric and isokinetic concentric tests. Methods The strength of trunk extensors and flexors were measured by isometric and isokinetic concentric tests during trunk flexion and extension in 50 healthy subjects, and the peak torque of flexion and extension (FPT and EPT) and the ratios of FPT/EPT were analyzed with correlation and regression analysis. Results The FPT and EPT of trunk flexors and extensors were positively correlated (r_F=0.827,P0.05, respectively), the regression equations of FPT and EPT were y^=8.158+1.097X and y^=-12.375+0.781X, respectively. Conclusion The isometric test of the trunk extensors and flexors could assess accurately the changes of the trunk muscle strength without aggravating pain and diseases. It is more reasonable to evaluate the stability of trunk with the FPT/EPT ratio at neutral position.

Objective:To investigate the efficacy and safety of ticagrelor and clopidogrel in patients with coronary atherosclerotic heart disease (CHD) and hyperhomocysteinemia (Hhcy).Methods:A total of 101 patients with CHD complicated with HHcy who had successfully undergone percutaneous coronary intervention (PCI) were enrolled. They were divided into ticagrelor group ( n=49) and clopidogrel group ( n=52) according to the different antiplatelet drugs used. The clinical data of the two groups were collected, and the incidence of major cardiovascular and cerebrovascular adverse events (MACCE) and bleeding events in one year were compared between the two groups. Results:There was no statistical difference in baseline datas and PCI datas between the clopidogrel and ticagrelor groups ( P>0.05). Compared with clopidogrel group, ticagrelor can reduce the total MACCE (8.16% vs 32.69%, P<0.05) and the incidence of unstable angina pectoris events (0 vs 13.46%, P<0.05) in patients with hyperhomocysteinemia PCI 1 year after operation. The incidences of ischemic stroke, unstable angina pectoris, recurrent myocardial infarction, and cardiogenic death were compared separately between the two groups, and the difference was not statistically significant ( P>0.05). The incidence of major bleeding events, minor bleeding events, and minimal bleeding events were similar between the two groups, and the difference was not statistically significant (4.08% vs 0; 4.08% vs 1.92%; 20.41% vs 9.62%; P>0.05). Conclusions:In patients with CHD and Hhcy, ticagrelor can play a better antithrombotic effect, reduce the incidence of ischemic events, and has good security, which is more worthy of clinical recommendation.

Objective To investigate the effect of nitric oxide(NO)on the prostatic proliferation/apoptosis in rat models. Methods Twenty adult male rats were randomly divided into 3 groups.Group 1 were normal controls (n=6);group 2 (n=7) and group 3 (n=7) were treated with subcutaneous injection of nitric oxide synthase (NOS) inhibitor-L-NG-Nitroarginine methyl ester (L-NAME) 50mg/kg and 100mg/kg, bid, respectively.The weight of the prostate was measured after 2 weeks and morphological changes were examined with light microscope.Detection of ki-67 and TUNEL in prostatic epithelial cells were undertaken so as to assess the proliferation and apoptosis index.The protein and mRNA expression of NOS were analyzed by means of immunohistochemistry and RT-PCR. Results The prostate weight of 3 groups was not significantly different.Compared with group 1, remarkable atrophy of prostatic epithelial cells,marked decrease in proliferation rate of epithelial and interstitial cells, and significant increase in apoptosis rate of epithelial cells were noted in group 2 and group 3 (P

AIM: To study the influences of P1 promoter activity of furin gene on the functions of hepatocytes in patients with liver cirrhosis.METHODS: The patients with liver cirrhosis of 180 cases were recruited.The single nucleotide polymorphism(SNP-229 C/T) in P1 promoter of furin gene was genotyped using competitively differentiated polymerase chain reaction.The relationships between the promoter activity based on genotyping and the serum levels of liver enzymes,total bilirubin,albumin and prothrombin were observed.RESULTS: The distribution frequencies of allele C and T were 75.3%(271/360) and 24.7%(89/360).Those of genotypes CC,CT and TT were 62.2%(112/180),26.1%(47/180) and 11.7%(21/180),respectively.The distribution frequencies of the genotypes were not related to the serum levels of major liver enzymes,albumin,total bilirubin and prothrombin,except for alkaline phosphatase and ?-glutamyl transferase.CONCLUSION: The activity of furin promoter exerts no effects on the main functions of hepatocytes,suggesting that furin may be a new therapeutic target for HBV infection.

AIM:To investigate the role of p38 MAPK signaling pathway in the receptor-mediated endocytosis.METHODS:The effects of p38 MAPK on the receptor-mediated endocytosis were observed by using Alexa 594-conjugated Transferrin,in the presence of p38 specific inhibitor SB203580 or ERK pathway specific inhibitor PD98059,or using p38 knockout techniques.RESULTS:In the process of receptor-mediated endocytosis,p38 was activated by phosphorylation.Furthermore,the receptor-mediated endocytosis was inhibited by pretreatment with SB203580 or p38 knockout,while pretreatment with PD98059 had no effect on this process.CONCLUSION:p38 MAPK signaling pathway plays a role in the regulation of receptor-mediated endocytosis.

Objective To investigate the clinical value of double contrast-enhanced ultrasonography (DCUS) in the macroscopic classification of rectal carcinoma. Methods Seventy-one patients with rectal carcinoma were examined by ultrasound after intrarectal infusion and intravenous bolus injection of SonoVue preoperatively. And three types were divided according to the shape of the tumor:protruding type, ulcerative type and invasive type. After surgery, DCUS and perfusion contrast-enhanced ultrasonography (PCUS) were compared with final pathologic results respectively, and the relationship between general tumor type and TN staging were analyzed.Results The accuracy of DCUS [88.7%(63/71) ] in macroscopic classification of rectal carcinoma was significantly higher than that of PCUS [73.2%(52/71) ](χ2=5.534,P<0.05). For the invasion depth into the intestinal wall, the protruding type was mainly in T1, T2 and T3 stages while ulcerative and invasive type in T2, T3 and T4 stages (χ2=12.322, P<0.05 ). For the stage of lymph node, the protruding type was mainly in N0 and N1 while ulcerative and invasive type in N1 and N2(χ2=6.733,P < 0.05 ). Conclusions DCUS, with its high accuracy, is a new valuable method for macroscopic classification of rectal carcinoma.In the aspect of intestinal wall invasion and the lymph node, protruding type is less severe than ulcerative type and invasive type.
