Objective To investigate the application value of prescription examination in the management of antimicrobial agents in hospital.Methods The prescriptions of antibacterials were examined,the irrational use of drugs was counted,and the application value of drug prescription examination in the management of antibacterial drugs in hospital was discussed.Results A total of 488 960 prescriptions were examined,including 133 534 prescriptions for antimicrobial agents,and 27.31％ for antimicrobial agents.Unqualified antibiotics use prescription in 60 086,unqualified rate was 45.00％,among them not standard prescription in 108,occupied 0.18％,medication unsuitable prescription in 59 907,occupied 99.70％,exceed prescription in 71,occupied 0.12％.Conclusion There is an irrational use of antibiotics in outpatient service,and the examination of antibacterial prescription should be strengthened so as to improve the level of rational use of antibiotics in hospital.

Objective To examine the blood lead levels and influencing factors among infants living in urban areas in Taiyuan.Methods A total of 216 healthy infants living in urban areas in Taiyuan who came to seek routine care during 2010 and 2012 were enrolled using questionnaire survey.Blood samples were collected and lead was meas-ured according to standard procedures.Results The total blood lead level was (31.54 ±22.24)μg/L,there was no significant difference between male and female.The infants whose blood level was less than 50 μg/L took the biggest proportion(80.56%),the infants whose blood level was among 50 -99μg/L and whose blood level more than 100μg/L were 19.44% and 0.00% respectively.Coal to cook,mother often catching hair,using prickly heat,sucking on the hand,washing hands before meals,living in storefront and playing time in roadside were associated with infantile blood lead level.Conclusion The key influencing factors the of the blood lead levels of infants are infantile living environ-ment and the keeper's awareness of preventing lead.

To investigate the effect of the case-centered teaching method in biochemistry teaching. 47 students were divided into two groups :the study group and the control group.The casecentered teaching method was used in the studying group.The control group was taught by traditional method.The final examination showed that the results of the studying group were better than the control group.

As a novel T cell population,Th17 cells are demonstrated to play an important role in autoimmune diseases,including Crohn' s disease.Several recent studies indicate the specific contributions of IL-23/Th17 axis and cytokines secreted by Th17 cells to the inflammatory bowel disease.This article is dedicated to describe the correlation between Th17 cells and Crohn' s disease.

This study was aimed to investigate the dose-response relations and synergy effects of bioactive components in Ginkgo bilobaon antiplatelet aggregation and DPPH free radical scavenging.The antiplatelet aggregation experiment and DPPH free radical scavenging experiment were conducted respectively to investigate the dose-response relations and synergy effects.Firstly,the effect of inhibiting platelet aggregation induced by PAF of ginkgolides in rabbits was investigated.And then,the effect of DPPH free radical scavenging by ginkgo flavonoids was also investigated.Finally,the synergy effects among effective components were studied.The results showed that ginkgolide A,ginkgolide B,ginkgolide C and bilobalide had dose-response relations on antiplatelet aggregation.Quercetin,kaempferol and isorhamnetin had DPPH free radical scavenging effects with dose-response relation.It was concluded that ginkgolide had the dose-response relation on antiplatelet aggregation.Ginkgolide A and ginkgolide B had synergy effect.Ginkgo flavonoids had DPPH free radical scavenging effect.Quercetin and isorhamnetin had synergy effect.

Impaired recognition of foreign nucleic acid initiates abnormal mucosal immune responses in intestine.Very little is known on how microbial DNA activates intracellular DNA sensors and controls the function of antigen-presenting cells to shape mucosal immune responses in inflammatory bowel disease (IBD).In current review,we will introduce mucosal dendritic cell population,describe newly identified cGAS-cGAMP-STING complex,and identify certain IBD susceptibility genes that associate with impaired microbial DNA recognition in human.

Objective To construct the lentiviral RNA interference vector targeting TPX2 and to obtain the human cervical cancer HeLa cell strain stably infected by TPX2-shRNA for studying the relationship between human cervical carcinoma and TPX2 gene.Methods By targeting TPX2 gene,four double-stranded DNA hairpin structures corresponding to shRNA were designed,synthesized and connected with Pglv2-U6-Puro to construct the recombinant plasmids.Then these recombinant plasmids were transformed into DH5α competent cells.The positive clone was extracted and transfected into 293T cells for virus packages after sequenced correctly.Human cervical carcinoma HeLa cell infected by these recombinant lentiviral was screened by Puromycin,then stable cell strain was obtained.The silencing effect of TPX2 in HeLa cell was detected by RT-fluorescent quantitative PCR and Western blot.Cell cycle and cell apoptosis wer detected by Flow cytometry.Results Sequencing results confirmed that 5 lentiviral was packaged successfully.The steady cell strain transfered TPX2-shRNA was screened with 0.4 μg/mL puromycin.HeLa cells infected by recombinant lentivirus all play the gene silencing effect especially in the group of TPX2-shRNA-1.In the group of TPX2-shRNA-1,TPX2mRNA (0.21 ± 0.07) and protein (0.19 ± 0.28) rela tive expression level is lower than those in the control group (1.08±0.07) (P＜0.01) and(0.64±0.03) (P＜ 0.01)respectively;G2 and S-phase cells are higher than those in the control group (P＜0.05)and the apoptosis rate was significantly more than those in the control group (P＜0.05).Conclusions The effective TPX2 genetic interference sequence was obtained,lentiviral vectors carrying TPX2shRNA was successfully constructed,and the HeLa cell strain with TPX2 silenced was successfully screened,which lay the research foundation for the study of the role of TPX2 in cervical cancer.

Through analyzing the children's pre-hospital transport,emergency medicine,intensive care medicine,nursing,professional training and research,we reviewed the current status of construction and issues of pediatric emergency and critical care system,then put forward recommendations of its development.

Objective To investigate the relationship between coronary myocardial bridge and the symptoms of the patients and its related factors, and to provide evidence for rational treatment. Methods Sixty-one patients di-agnosed as myocardial bridge by coronary angiography and the examination of nuclide myocardial perfusion imaging were recruited and their clinical data was analyzed retrospectively. The patients were divided into ischemic group and non-ischemic group according to the nuclide imaging, and were followed up on the compliance of β-blocker taking and the symptoms. Results Among the 61 patients ,7 patients were ischemic,and the others were non-ischemic. There was no significant difference on symptoms between the two groups (P>0.05). The prevalence of Grade Ⅲ narrowing was higher in ischemic group (6/7) than that in the non-ischemic group (18/54) (χ~2=5. 009, P = 0.024) ,and the ischemic patients with Grade Ⅲ narrowing were older than those in the non-ischemic patients. Two patients in the ischemic group did not insist on taking β-blocker and their symptoms did not change,40 patients in the non-ischemia group did not insist on taking β-blocker,of which 33 patient's symptoms were improved. The symp-toms of all patients with good compliance of β-blocker taking were improved. Conclusions The symptoms of some patients are unrelated with myocardial bridge and treatment is not recommended.
