Objective To compare coagulation data measured with domestic produced and imported coagulation testing solutions on SD rat and human by testing prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time(TT), fibrinogen(FIB).Methods Blood samples were obtained from SPF SD rat and human .Domestic produced and imported coagulation testing solutions were applied to test PT , APTT, TT, and FIB.Results Compared to rat data measured with imported coagulation testing solution , data measured with domestic produced coagulation testing solution of PT, APTT, FIB was significantly higher (P<0.05), while, data of TT was statistically lower(P<0.05), and there was no obvious difference in human blood coagulation .Conclusion The data measured with different coagulation testing solution varies on SD rat , so the laboratories are required to establish reference data according to different products .

Objective To study the influence of different routes of keyhole limpet hemocyanin ( KLH) immuniza-tion on the T-cell-dependent antibody response in mice.Methods SPF Kunming mice were divided into four groups: the intravenous injection group, subcutaneous injection group, intraperitoneal injection group and control group.Each mouse was injected 200 μg KLH intravenously, subcutaneously or intraperitoneally daily for consecutive 10 days, respectively. Mice in the control group were given solvent injection only.Serum concentration of IgG stimulated by KLH antigen was measured 7 days after the last dosing.Spleen was isolated to calculate the organ coefficient and examined by pathology u-sing hematoxylin and eosin staining.Results Intravenously, subcutaneously and intraperitoneally administered KLH stimu-lated the generation of secondary lymphoid follicles and germinal center to varying degrees, B cell apoptosis, increased a-mount of cells in the marginal zone and other pathological changes were observed in the spleen.Intravenous and intraperito-neal administration of KLH led to more pronounced pathological changes compared with that in the subcutaneous injection group.All of the three administration routes of KLH induced generation of IgG antibody, significantly higher than that in the control group (P<0.05).Intravenous injection of KLH generated the highest concentration of IgG and organ coefficient among the three administration routes ( P<0.05) .Conclusions Different immunization routes do affect the production of IgG antibody, organ coefficient and pathological changes in the spleen, and these differences should be taken into consider-ation when analyzing the T cell dependent antibody response in mice.

Objective To investigate the relationship between peripheral inflammatory cytokines and anxiety symptoms in patients with the first?episode generalized anxiety disorder. Methods 48 patients diagnosed with the first?episode generalized anxiety disorder according to ICD?10 criteria and 48 healthy sub?jects were recruited. Peripheral levels of IL?1, IL?2, IL?4, IL?5, IL?6, IL?8, IL?10, IL?12p70, GM?CSF and IFN?γ of both groups were evaluated by enzyme?linked immunosorbent assay ( ELISA) ,and CRP was evalua?ted by immunoturbidimetric method. Generalized Anxiety Disorder Scale( GAD?7) and State?Trait Anxiety Inventory ( STAI ) were used to assess the levels of overall anxiety, state anxiety and trait anxiety. Results The levels of CRP ( ( 1. 19 ± 0. 80 ) mg/L vs ( 0. 68 ± 0. 70 ) mg/L, t=3. 31 ) , IL?1α( ( 70. 34 ± 3.60)pg/ml vs (16.94±3.42)pg/ml, t=74.50),IL?2((7.25±3.42)pg/ml vs (4.95±2.31)pg/ml, t=3.85), IL?4((102.02±73.14)pg/ml vs (75.55±32.78)pg/ml, t=2.29),IL?6((12.55±2.37)pg/ml vs (2.71±1.35) pg/ml, t=14.79),IL?8((44.64±16.21)pg/ml vs (35.69±11.70)pg/ml, t=3.10),IL?12((18.16±24.17) pg/ml vs (10.82±4.72)pg/ml, t=2.06),IFN?γ((23.32±15.52)pg/ml vs (16.48±6.80)pg/ml, t=2.79), GM?CSF((19.07±11.12)pg/ml vs (13.40±8.54)pg/ml, t=2.80) in patients with the first?episode general?ized anxiety disorder were significantly higher than normal controls(P<0.05) . Both SAI and TAI had signifi? cantly positive correlation with the levels of IL?1α, IL?2, IL?6, IL?8, IL?12, IFN?γ and GM?CSF ( r=0.24?0.76, P<0.05) . Conclusion The levels of some peripheral inflammatory cytokines in patients with the first?episode generalized anxiety disorder are significantly increased,and they have positive correlation with gener?al anxiety,state anxiety and trait anxiety,which may suggest some immune system defects in the patients.

The effect of cholesterol ester transfer protein(CETP) on SR-B1 mRNA expression in mouse liver was investigated.The results demonstrated that CETP transgenic mice showed lower serum total cholesterol and high density lipoprotein-cholesterol levels but higher total cholesterol and cholesterol ester content in liver when compared with wild type mice(P＜0.05).The expression of SR-B1 mRNA in liver of CETP transgenic mice was significantly lower as compared with the control group(P＜0.05).

Objective To investigate use of oral antihypertensive drugs among community hypertensive patients in Shanghai and find out factors related to their unreasonable use to direct their clinical use. Methods Seven hundred and three hypertensive patients were surveyed with questionnaire by stratified cluster sampling at three neighborhoods and one village of Dahua community, Baoshan district, Shanghai during April to June 2009 to understand their use of antihypertensive agents, including kinds and forms of drugs, rationale of drug use. Results Five hundred and eighty-two (82. 8% ) of 703 hypertensive patients interviewed were using antihypertensive drugs, 271 (38. 5% ) of them used only one kind of non-compound antihypertensive drug, 182 (25.9%) used one kind of compound agent, 311 (53.4%) used two or more kinds of drugs in combination, including 117 patients ( 16. 8% ) used two kinds of agents combined and 12 patients ( 1.6% ) used three kinds of agents combined. Two hundred and sixty-six (47.5%) patients took orally calcium-channel blockers and 205 ( 35.2% ) used compound agents. Conclusions Frequency of combined use of two or more kinds of antihypertensive agents is reasonable and significantly higher than that of use of one kind of drug at Dahua community in Shanghai. Calcium channel blocker plays a predominant role in treatment for hypertension, non-long-acting compound agents are used in a higher proportion. But,guidelines for hypertension prevention and treatment are not so well complied with in local hypertensive patients. So, it is suggested that training for community physicians and management for standard use of antihypertensive agents at community should be strengthened further.

BACKGROUND:It remains controversial about the clinical outcomes of bone fil ing mesh containers (BFMCs) and percutaneous kyphoplasty (PKP) in pain relief, kyphosis correction, vertebral height restoration and reduction of cement leakage. OBJECTIVE:To compare the clinical outcomes of BFMCs and PKP for osteoporotic vertebral compressive fracture. METHODS:A total of 90 patients with osteoporotic vertebral compressive fracture were equivalently randomized into two groups, fol owed by treated with BFMCs or PKP, respectively. During a more than 3-month fol ow-up, pain relief, kyphotic angle, the vertebral height and cement leakage were observed in the two groups to assess the therapeutic effects. RESULTS AND CONCLUSION:Pain in al patients was relieved at 24 hours after operation. There was no significant difference in pain relief between two groups (P>0.05). PKP was more effective to restore the vertebral height (P<0.05), while BMCFs significantly reduced the leakage rate of bone cement (P<0.05). These results suggest that BFMCs and PKP have their own advantages in the treatment of osteoporotic vertebral compressive fracture, but both exert analgesic effects.

The five volumes of Annals of National Medicine in Yunnan contain more than 1040 kinds of ethnic medicines and national medicines experiene that are commonly used by 25 minority nationalities in Yunnan.Among them,there are 147 species of toxic drugs,including five with fatal toxicity,14 with strong toxicity,57 with toxicity,and 71 with mild toxicity.In order to guarantee the validity and safety of national drug use,Yunnan Institute of Materia Medica applied modern science and technology to study the safety,efficacy and pharmacognosy of 30 kinds of commonly used toxic folk drugs contained in Annals of National Medicine in Yunnan.This paper chooses five typical national medicinal herbs Stephania delavayi,Euphorbia neriifolia,Alocasia cucullata,Achillea wilsoniana and Chamaenerion angustifolium,and summarizes their national medicinal and toxicity experience.The results of acute toxicity test showed that the five national medicinal herbs are toxic.The pharmacodynamic experiments showed that S.delavayi has analgesic action,E.neriifolia has anti-inflammatory action,A.cucullata has analgesic and antitussive effects,Ach.wilsoniana has analgesic effect,and C.angustifolium has analgesic and anti-inflammatory effects.

Objective To observe whether treatment with cannabidiol (CBD) affect nonalcoholic steatohepatitis (NASH) induced by methionine choline-deficient diet (MCD) in rats and investigate the underlying molecular mechanism. Methods Sixty-three adult male SD rats were randomly divided in to three groups as follows: Control group (rats fed with normal diet), MCD group (rats fed with MCD and MCD+CBD group [rats fed with MCD and treated with cannabidiol, 2mg/(kg.d), i.p.]. Ten weeks later, steatohepatitis and fibrosis were evaluated by hematoxylin-eosin and Masson staining, respectively. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were measured by using an automatic biochemical analyzer and hepatic levels of cholesterol and triacylglycerol were determined with kits. Autophagic flux in livers was evaluated by Western blotting. Results Treatment with cannabidiol reduced ratio of liver/body weightratio (4.2%±0.6% versus 3.1%±0.6%, P<0.05), histological scores (4.7±1.1 versus 2.2±0.5, P<0.05) and fibrosis (1.4%±0.4% versus 0.8%±0.3%, P<0.05) in rat livers, lowered levels of ALT (214.5±54.1U/L versus 92.1±36.0U/L, P<0.05) and AST (175.9±55.2U/L versus 70.8±24.9U/L, P<0.05) in serum, attenuated hepatic fat accumulation (cholesterol, 182.4±42.7mmol/mg protein versus 101.0±33.8mmol/mg protein, P<0.05; triglyceride, 71.4±12.5mmol/mg protein versus 38.7±11.1mmol/mg protein, P<0.05), and down-regulated mRNA expression of Col1A1 (2.9±0.4 versus 1.6±0.3, P<0.05) in livers of rats fed with MCD. Furthermore, cannabidiol led to the LC3 turnover (LC3-Ⅱ/LC3-I, 37.1±10.8 versus 71.2±17.1, P<0.05) and p62 decrease (202.4±40.9 versus 125.8±32.7, P<0.05) in the livers of MCD-fed rats. Conclusion Treatment with cannabidiol could relieve MCD-induced NASH in rats, at least in part, by autophagic flux promotion.
