OBJECTIVE To introduce the methods of hospital disease prevention and control and advance the level of infection management.METHODS We constituted and administered thoroughly hospital regulations of infection prevention and control according to our country and PLA′s laws and statutes.RESULTS To eliminate effectively the outbreak and epidemic of the hospital infection and cross infection,and complete the work of hospital disease prevention and control that leads appointed us.CONCLUSIONS Disease prevention and control are the key to the infection control in hospitals.

This article aims at exploring ways of integrating subject of pathobiology under the guidance of scientific outlook on development and improving and enriching pathobiology inte-gration and construction through curriculum systems recombination and integration,teaching con-tents optimization to reflect the latest research progress,network education platform establish-ment,comprehensive and exploratory laboratory course teaching system construction,new syl-labus and teaching material making up.

Pathogen biology is a main course of curricula in medical university.In developing quality courses,we optimized Pathogen biology course content,created the PBL teaching mode suitable for this course,set up network teaching platform,enhanced teachers' qualification,constructed comprehensive and exploratory experiment teaching system,wrote new teaching syllabus and other measures,made the Pathogen biology course construction more reasonable and perfect.

A giant basilar artery aneurysm of young woman with endocrine disturbance was misdiagnosed as a large pituitary adenoma and treated surgically via a trans-sphenoidal approach was planned.But the neurosurgery was finally aborted because of massive bleeding during the procedure. One year later, a cerebral angiography confirmed this basilar artery aneurysm was obviously regressed and then endovascular coiling was successfully performed. No neurological complication occurred post-procedure and the endocrine dysfunction symptom was obviously improved.

Objective To study the clinical efficacy of intra-arterial thrombolysis with recombinant tissue plasminogen activator (rt-PA) for the treatment of ischemic cerebrovascular disease caused by cerebral thrombosis. Methods A total of 245 patients accepted by our hospital during May 2013 and July 2015 were divided into the observation group (n=148) and the control group (n=97). All patients were given conventional process for controling blood pressure and blood lipids. Patients in observation group received intra-arterial thrombolysis with rt-PA, while patients in control group accepted conventional treatment. At the time of admission, the demographic characteristic, vascular influencing factors, baseline clinical findings, laboratory findings and neurological deficits were collected. The improvement of neurological function was evaluated by the modified Rankin scale 3 months after treatment. The levels of fibrinogen (FIB), D-Dimer, activated partial thromboplastin time (APTT) and thrombin time (PT) were measured before and 24 h after the treatment. Results There were no significant differences in demographic characteristic and general clinical data between the two groups ( P>0.05). The proportion of patients with improved neurological function was significantly higher in observation group than that of the control group (83.11％vs. 53.61％, P<0.05). There were no significant difference in coagulation index and fibrinolysis index before treatment between the two groups (P>0.05). Twenty-four hours after the treatment, the levels of FIB, D-Dimer, APTT and PT were significantly improved in the observation group compared with those before treatment. The level of FIB was significantly decreased, D-Dimer was significantly increased, APTT and PT were significantly prolonged in observation group compared with those of control group (P<0.05). Conclusion The rt-PA can effectively dissolve thrombosis and correct the coagulation system and fibrinolytic system.

To fully incarnate"specialization"peculiarities of microbiology teaching courses by means of optimizing microbiology teaching contents and curriculum systems,and making up a new syllabus suitable to different specialties will lay a very solid foundation for cultivating medical talents with specialty traits.

To explore the promotion of formative assessment for teaching, the surgery teaching and research section of Institute of Pediatric has carried out formative assessment in theory teaching of pediatric medicine pediatric surgery for seven-year program for two consecutive years , and the teaching effects and assessment results have been made detalled analysis. The results shows that for-mative assessment combining with summative assessment can guide the students to adjust learning method in time and improve teaching methods effectively. Compared with the pure summative evalua-tion, formative assessment has enhanced the students' learning initiative, and improved their abilityof learning and solving problems. Formative assessment can comprehensively measure the overall quality of students.

OBJECTIVE Study the kidney toxic effects caused by burning coal endemic arsenism in rats,application bench mark dose (BMD) method to investigate the bench mark dose of urinary arsenic (UAs)and the changes in bio markers of renal function.METHODS Wistar rats were fed for 90 d with arsenic 0,25,50,100 mg·kg -1 conta minated feed.Urinary arsenic,kidney arsenic and renal function indicators were determined,and routine pathological and fibrosis of kidney were exa mined.UAs as the exposure bio marker,Uβ2-MG,UNAG and UALB for the effect bio markers,application bench mark dose method to calculate the BMD and BMDL of UAs for each effect bio markers.RESULTS UAs,KAs, Uβ2-MG,UNAG,UALB levels of rats in arsenic 100 mg·kg -1 group were increased than normal group (P <0.05);In light microscope,the results of HE staining of rat kidney in all arsenic dose groups showed infla mmatory cell infiltration,renal tubular epithelial cell swelling,renal interstitial capillary dila-tion,congestion and other varying degrees pathological changes,and the results of masson staining showed varying degrees of tubulointerstitial fibrosis;UAs as the exposure bio marker,Uβ2-MG,UNAG, UALB for the effects of mark,the BMD and BMDL of UAs for Uβ2-MG,UNAG,UALB were calculated, the BMD values were 998.9,1213.5,1386.9 μg·g -1 Cr,the BMDL values were 660.5,803.6 and 909. 4 μg·g -1 Cr,respectively.CONCLUSION Burning coal arsenic pollution can cause kidney da mage in rats,mini mal change nephropathy may be the pri mary pathological in the coal arsenic conta mination of kidney da mage.The BMD and BMDL of UAs were 998.9,660.5 μg·g -1 Cr,the early changes of renal function of burning coal arsenism in rats;it is reco mmended to use the more sensitive bio markers Uβ2-MG to calculate the biological exposure li mits on renal injury caused by arsenic.
