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.

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.

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.

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.

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.

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.

This study was aimed to investigate the inhibitory effect of emodin on the proliferation of HEL cells, the inducing apoptosis effect of HEL cells and their mechanisms. The proliferation inhibition was detected by MTT method; the change of morphology was observed by AO/EB stains; the cell cycle and apoptosis was analyzed by flow cytometry; the expressions of Akt, P-Akt, P-GSK3β and HSP70 proteins were determined by Western blot. The results indicated that emodin displayed significant anti-proliferative effect on HEL cells in a dose dependent manner(r = 0.99), with IC(50) value of 4.19 µmol/L; AO/EB stains showed that the morphology of HEL cells obviously changed after emodin treatment for 24 hours, and at 24 and 48 hours the apoptosis rates of HEL cells treated by emodin were (27.35 ± 1.68)% and (58.49 ± 1.55)% respectively. Compared with blank control group, the cell ratio in G(0)/G(1) phase increased while that in S phase decreased (p < 0.01); the expression of Akt protein was not changed (p > 0.05), and that of P-Akt, P-GSK3β and HSP70 proteins were down-regulated (p < 0.05). It is concluded that emodin efficiently inhibits the HEL cell proliferation and induces apoptosis of HEL cells, which may be related to the down-regulation of P-Akt, P-GSK3β and HSP70 proteins expression.

In this study, 31 Notopterygium incisum populations were analyzed using ITS sequences to investigate the genetic structure. The results showed that: the ITS region ranged in size from 634 to 635 bp and base composition was with high G + C content of 57.8%. Thirty-one polymorphic sites were detected from 402 sequences of 31 populations of N. incisum, and the proportion of polymorphic sites was 4.88%, in which parsimony informative sites were up to 12. And 31 haplotypes were identified based on these polymorphic sites. Molecular variance analysis (AMOVA) indicated that high genetic differentiation (57%) existed among population, and gene flow was low (N(m) = 0.38) among populations. Phylogenetic relationships of 31 haplotypes were analyzed using NJ method with N. forbesiias an out-group. Phylogenetic analysis showed that 31 haplotypes from different populations mixed together and did not form distinct geographically separated clades.
