OBJECTIVETo elucidate the effect of hydroxysafflor yellow A ( HYSA) on the proliferation of vascular smooth muscle cells (VSMCs) and the related mechanism.

METHODSVSMCs derived from SD rats were treated with DMEC culture medium (Control), 10 ng/ml PDGF (PDGF group), pretreatment with HYSA at different doses (1, 5, 10, 20, 40, 60 µmol/L) for 24 h then cotreatment with PDGF. After 24 h, MTT assay, Western blot and immunohistochemical staining were performed to evaluate the inhibitory effects of HYSA on VSMCs proliferation.

RESULTSHYSA inhibited PDGF induced VSMCs proliferation in a dose-dependent manner, dowregulated proliferating cell nuclear antigen (PCNA) expression and blocked PDGF activated PDGFR-MEK-ERK1/2 signaling pathway.

CONCLUSIONSHYSA inhibits VSMCs proliferation possibly via downregulating the expression of PCNA and blocking MEK-ERK1/2 signal transduction in VSMCs.

Objective To investigate the status of soil fertility of Good Agricultural Practices ( GAP) base for Spatholobus suberectus Dunn. (SSD) in Pingyuan county of Guangdong province, thus to provide reference for GAP research and the subsequent fertilization for SSD. Methods The deep layer and superficial layer of GAP soil were collected for the physiochemical detection and nutrient assay. Compared with the classification standard of the second national general soil investigation, single base soil fertility index was diagnosed and the comprehensive soil fertility was evaluated with modified Nemoro Index. Results The soil pH value and the contents of exchangeable calcium and magnesium were unbalanced, and the contents of macroelements of nitrogen and phosphonium, microelements, and organic matter were low. Therefore, the measures for improving the base soil fertility should be as follows: ( 1) soil amendments of bentonite, gypsum and slaked lime should be used to adjust the soil pH value; ( 2) each plant should be given 10 kg of slaked organic fertilizer as base fertilizer; ( 3) in the process of nurturing, some special micro-fertilizer solution should be used to treat the cut slips, and 5 kg of urea should be used for every 667 meter square of land; ( 4) besides compound fertilizer, every 667 meter square of land should be fertilized with 15 kg of ammonium dihydrogen phosphate for the supplement of nitrogen and phosphorus, and slaked lime and magnesium carbonate should be used for the supplement of soil moderate-quantity elements after transplantation. Conclusion The comprehensive fertility of Pingyuan GAP base for Spatholobus suberectus Dunn. is at low level, and should be improved in combination with GAP requirements.

Objective To observe effects of problem-based learning(PBL) combined with case-based study (CBS)teaching mode in clinical teaching in intensive care unit(ICU). Methods Students from ICU of Fangcun Branch of Guangdong Provincial Hospital of Traditional Chinese Medicine from March 2011 to February 2012 were divided into treatment group (31 cases, with PBL combined with CBS teaching mode) and control group (34 cases, with the traditional teaching mode). Scores of two groups were compared and analyzed and questionnaire survey was conducted in treatment group. Data were processed by SPSS 13.0 statistical software. Measurement data were compared by t-test and data of heterogeneous variance were compared by rank-sum test. Results Treatment group achieved better scores ((85.26 ±5.96) in theory examination and (80.59 ±7.33) in case-analyzing examination) compared with those of control group ((79.17 ±7.31) in theory examination and (76.02 ±9.27) in case-analyzing examination)(P<0.05). PBL combined with CBS teaching mode can stimulate learning interests but it was lack of systematization; most students did not volunteer to speak. Conclusion PBL combined with CBS teaching mode has certain advantages in ICU clinical teaching.

ABSTRACT:Objective To explore the role of HIF‐1αin the pathogenesis of hepatopulmonary syndrome (HPS) and its relationship with GRP78 .Methods The HPS model in rats was induced by multiple pathogenic factor .The samples were assessed by using Western blotting analysis for HIF‐lα, GRP78 and VEGF164 . The expressions of VEGFR‐2 and CD105 were observed by using immunohistochemical staining .Results The protein level of HIF‐1αwas significantly increased in HPS group at week 8 compared with that at week 4 and 6 groups and corresponding normal control groups .With the development of HPS ,protein level of GRP78 was gradually increased at each time point significantly and reached the highest level at week 8 ;protein level of VEGF164 showed a similar change with GRP78 ,but the peak was at week 6 .Immunohistochemical results showed that the protein expressions of VEGFR‐2 and CD105 were gradually increased in lung tissue as HPS progressed .The protein level of GRP78 was positively correlated with HIF‐1α,VEGF164 ,VEGFR‐2 and CD105 ,respectively (P<0 .05) .Conclusion HIF‐1αis most likely together with GRP78 to play a critical role in promoting pulmonary microvascular remodeling in the pathogenesis of HPS in rats .
