Objective To observe the effect of Fasudil on inflammatory factors (TNF-α and IL-8) secreted by astro-cytes.Methods Primary rat spinal astrocytes were cultured and randomly divided into three groups :control group ,oxygen-glu-cose deprivation group (OGD group) and Fasudil group.The culture media were harvested at different time points (0 ,3 ,6 ,12 , 24 h) for detection of the concentration of TNF-αand IL-8 by ELISA.Results Compared with the control group ,the concentra-tions of TNF-αand IL-8 in OGD group were significantly increased at each time point (P<0.05);in Fasudil group ,the concen-trations of TNF-αand IL-8 increased at some time points ,but they were much lower than in OGD group (P<0.05) .Conclusion OGD can promote the secretion of TNF-αand IL-8 by astrocytes in vitro ,which can be effectively inhibited by Fasudil.It is suggested that Fasudil plays an important role in regulating the levels of TNF-αand IL-8 secreted by astrocytes.

The expression of DNA methyltranferase 1 (DNMT1 )mRNA and protein in 20 controls of normal oral mucosa tissue and 43 cases of oral squamous cell carcinoma(OSCC)was detected by Real-Time PCR and immunohistochemical staining and Western blot respectively. DNMTl mRNA CT values in OSCC and the controls were 0.958 6 ±0.986 6 and 0.459 5 ±0.525 8 respectively(Z =-2.028,P <0.05), The positive expression of DNMT1 protein in OSCC and the controls was 87% and 25% respectively(P <0.05).DNMT1 may play a role in the development of OSCC.

Objective To study the changes of arterial blood lactate(ABL) and serum enzymes activities and thier correlation.Method Lactate dehydrogenase(LDH),alkaline phosphatase(AKP) and creatine kinase(CK) in serum were determined in sixty-four critical patients in the intensive care unit(ICU) at admission immediately,following 24h,48h and 72h,respectively.The patients was divided into three groups:favorable,survival and death groups.Results Before treatment,ABL level was(3.9?2.5,2.9?1.3 and 3.8?2.3)mmol/L in favorable,survival and death groups respectively.Although ABL in favorable and survival groups were decreased gradually to normal level during 24～72h,the death group showed that the decline was very slowly it still persistent elevated in 72h.There was significanct difference between the death group and the favorable and survival groups(P

The revolution of moderm medical model promoted the infiltration and insection on Medical Science,Human social science and related subjects.Human social science is the guiding and ensuring on the mode of Biology-Psychology-Society-Environment built.It is the needs of times and inesorable trend of the development on medical science to promote the education of human social science and improve the synthetical quality of medical students.

Objective To study the changes of AT-III and PAI-1 in the blood of patients with sudden sensorineural hearing loss(SSHL) and investigate the relationship between their levels and the disease.Methods The levels of AT-III and PAI-1 in the blood of 44 patients with SSHL and 30 healthy volunteers were detected using chromogentic substrate method.Results The changes of AT-III and PAI-1 in the blood of patients with SSHL were correlated with the process of the disease.There was significant difference between the levels of AT-III and PAI-1 in the blood of patients within 3 days and that of patients beyond 1 week(P

Objective To observe the effect of acupuncture and auricular application in the treatment of puerperal hypogalactia.Methods 300 patients with puerperal hypogalactia,according to the principle of random, balanced,together,were divided into 3 groups:Chinese herbal medicine group and acupuncture combined with auricular group and massage group,each group in 1 00cases.Collected patients'informed consent,and obtained the hospital ethics committee approval.The clinical curative effect was observed.Results After 3 days,in the Chinese herbal medicine group 34 cases recovered,24 cases were markedly effective,efficient in 1 5 cases,27 cases were invalid.In the massage group 7 cases recovered,1 3 cases had marked effect,1 5 cases were effective,ineffective in 65 cases.In the acupuncture combined with auricular group 73 cases cured,1 3 cases were markedly effective,effective in 9 cases, 5 cases were ineffective.The total effective rate between the acupuncture combined with auricular group and Chinese herbal medicine group had significant difference(χ2 =9.600,P <0.01 ).The total effective rate between the acupuncture combined with auricular group and the massage group had significant difference (χ2 =1 3.400,P <0.01 ).The total effective rate between Chinese herbal medicine group and massage group had significant difference (χ2 =6.400,P <0.01 ).Conclusion Acupuncture and auricular application has obvious curative effect for patients with postpartum hypogalactia.

Objective To research the best extracting technology of simiaoyongan decoction.Methods As the total contents of chlorogenic acid and harpagoside to be evaluation indicator, adopted L9 (34 ) orthogonal design to select out the best extraction.The main determination was by HPLC method.Results Accounted by the total contents of the two composi-tions, the influential effects of the experimental results were extraction solvent >reflux times >the volume of extraction>the circumfluence time.Conclusion The best extracting technology is adding 10-fold times of 50% alcohol, percolating 1 hours, and three times.

Objective:To investigate the expression of insulin-like growth factor binding protein 3 (IGFBP-3) in salivary pleomorphic adenoma(SPA).Methods:The expression of IGFBP-3 protein in 40 cases of SPA(group SPA),40 of normal glandular tissue(group N) and 10 of salivary gland malignant tumor(group CA) was detected by Western blot.The expression of IGFBP-3 mRNA in 50 cases of SPA,50 of salivary gland normal tissue and 10 of CA was detected by qRT-PCR.Results:The expression(A value) of IGFBP-3 protein in group N,SPA and CA was 8.54 ± 3.95,4.78 ± 2.07,3.63 ± 2.27 respectively.The expression ration of IGFBP-3 mRNA of group N vs SPA or CA,P ＜ 0.05;SPA vs CA,P ＞ 0.05 (SPA/N was 0.654 ± 0.387,CA/N:0.452 ± 0.229) respectively,but showed no significance difference between SPA and the CA groups(P ＞ 0.05).Difference of IGFBP-3 mRNA expression was observed with different envelope infiltration of SPA (P ＜ 0.05),no significant difference was observed in different age,gender or relapse groups.Conclusion:IGFBP-3 Low expression of IGFBP-3 in pleomorphic adenomas may reduce the antagonism of IGF-1R,causing the proliferation of tumor cells and promote tumor formation.

Immunohistochemical method was used to investigate the morphology and distribution of the oxytocin immunoreactive (OXT-ir) neurons and their dendrites in the subependymal plexus (SEP) around the third ventricle (OXT-SEP). The OXT-ir neurons were of magnocellular neurosecretory type which often intercalated between the ependymal cells, their dendrites were generally long and straight and mostly paralleled to or traveled within the ependyma,some of them could protrude into the ventricle, and most of them appeared heavily vacuous and have a strong tendency of grouping into fascicles. The plexus was composed of dorsal and ventral parts, the former corresponding to the extent of the magnocellular paraventricular nuclei and was extensive and dense, the dendrites were well organized; the latter was more sparse. The cell bodies and dendrites within and between different parts might mix or contact with each other. The functional significance of the plexus is discussed.

This paper introduces the ideas and methods concerning the design of network-based curriculm of hepatobiliary surgery. Design of network-based curriculm should highlight independence of online learning,emphasize network-based resources to support learning.Net-work-based curriculm should emphasize the evaluation of learning effect.
