Objective:To observe the clinical efficacy of different therapies in treating straightened cervical curvature. Methods:A hundred patients with straightened cervical curvature were randomized into 5 groups to receive corresponding treatment. The clinical efficacies and the changes of cervical curvature in the five groups were compared. Results:Different therapies all produced certain effectiveness in treating cervical spondylosis patients. The total effective rates in the acupuncture group and tuina group were both 100%, and the rates in the traction group, oral medication group and Chinese medicinal application group were all lower than the rates in the acupuncture group and tuina group (P<0.05). It was shown that the more significant the change of cervical curvature, the more significant the clinical efficacy. Conclusion:Correcting the straightened cervical curvature is a way to swiftly release pain brought by cervical spondylosis; the optimization of different therapies ensures the achievement of long-term effectiveness; acupuncture and tuina are both effective in restoring the cervical curvature.

Objective To observe the effect of transforming growth factor β1 (TGF-β1) on thyroid peroxidase activity and the expression of mRNA in primary porcine thyrocytes, and approach its possible mechanism. Methods In vitro cultured porcine thyrocytes were divided into 0 μg/L(control group), 2, 5, and 10 μg TGF-β1/L groups.After cultured for 72 h, the cell survival rate was measured with methyl thiazolyl tetrazolium (MTT) assay and the thyroid peroxidase (TPO) activity was measured by guaiacol method. The expression of TPO mRNA was determined cell survival rates of 2, 5, 10 μg/L groups(85.26%, 75.14% and 63.21%) were significantly lower(all P < 0.05 ).significantly decreased as compared with the control group [(2.143 ± 0.102), all P < 0.05)], and the TPO of TGF-β1, the lower the expression of TPO mRNA [(0.875 ± 0.078), (0.466 ± 0.044), (0.273 ± 0.007)] compared with the control group[(1.419 ± 0.148), all P < 0.05)]. Conclusions The inhibiting effect of TGF-β1 on primary cultured porcine thyrocytes may be related to its mechanism of inhibiting TPO activity and reduced mRNA expression.

Objective　To explore the development of endogenous CO and its mechanisms in asthma.Methods　50 guinea pigs were equally separated 5 groups.After the models of asthmatic guinea pigs were established in 4 groups,3 groups of them were treated with dexamethasone,the specific stimulator(hemin)and inhibitor(Sn-PP)of HO-1 respectively.The rest of groups were asthmatic one and normal control one(NCG).From all tested animals,the COHb in blood and lung HO-1 activity were examined,the lung tissues were pathologically observed and immunohistochemically stained.Results　In asthmatic and hemin stimulated groups,the levels of COHb with enhanced expression of lung HO-1 and their activity were significantly increased compared with NCG(t=4.43～9.97,P＜0.01).For example,the lung HO-1 activities in asthmatic group were (881±361)pmol/(mg*pro*h),COHb (4.94±2.15)% respectively.In dexamethason prevented and Sn-PP inhibited groups,however,all determined levels were markedly reduced compared with asthmatic group(P＜0.01).Conclusion　The increased HO-1 had resulted in the growth of endogenous CO in asthma.

Eighty-five endophytic fungal strains were isolated from the roots、stems and leaves of Polygala tenuifolia Willd, among which, fifty-two from natural plants and thirty-three from cultivated ones. Sev-enty-six strains were classified as twenty-three fungal genera. The inhibitory activity screening to fourteen microbe were conducted research. The results showed that some endophytic fungi had remarkble inhibitory activities to Bacillus subtilis, Shigella sonnei, Escherichia coli, Candida albicans, Fusarium kyrushuense and they were all belonged to Fusarium, Alternaria, Aphanocladium respectively. All of the endophytic fungi isolated from Polygala tenuifolia showed no inhibitory activities to Staphyloccocus aureus, Salmonel-lae enteritis, Bibrio parahemolyticus.

Objective To investigate the decisional value of susceptibility weighted imaging(SWI) in intravenous thrombolytic therapy to acute cerebral infarction.Methods According to cerebral microbleeds(CMBs) by SWI, 35 cases of acute cerebral infarction in window-time random were divided into experimental group(14 cases) with CMBs and control group(21 cases) without CMBs.After intravenous thrombolysis, the number of hemorrhagic transformation(HT) was counted by SWI, and statistic difference was compared between the experimental group and the control group(P<0.05).Results After intravenous thrombolytic therapy of acute infarction,12 cases with HT among experimental group, and only 2 cases with HT among control group, there was significant statistically difference between two groups(P<0.05).Conclusion SWI sequence has greater sensitivity in detecting CMBs,and can also assess the state of blood brain barrier(BBB) and vascular wall indirectly.It plays a very important role in giving a decision in the treatment of intravenous thrombolytic with window-time.

OBJECTIVETo observe the therapeutic effects of Berberine Capsule (BC) on patients with mild hyperlipidemia.

METHODSTotally 102 mild hyperlipemia patients were recruited. All patients were suggested to have proper diet and physical activity as basic therapy for 1 month of run-in period. Totally 97 patients completed it. Then they were randomly assigned to the berberine group (the treatment group, 49 cases) and the placebo group (the control group, 48 cases). Patients in the treatment group took BC 300 mg, while those in the control group took placebo 300 mg, thrice per day for 3 successive months. Then placebos and BC were interrupted for 2 months (as washout period). All subjects received only diet control and physical activity during washout period. After washout period, placebos and BC were re-administered to all patients in the same way for 3 months. Body mass index (BMI), fasting plasma glucose (FPG), TG, TC, LDL-C, and HDL-C were assessed after run-in period, washout period, at month 1, 2, 3 after the first therapy, at month 1, 2, 3 after second treatment, respectively.

RESULTSCompared with the end of run-in period, TG, TC, and LDL-C decreased, and HDL-C increased in the treatment group (P < 0.05) after first 3 months of treatment. Compared with 3 months after the first therapy, TG, TC, and LDL-C increased and HDL-C decreased in the treatment group after washout period (P < 0.05). Compared with the end of wash- out period, TC and LDL-C decreased in the treatment group at month 2 after second treatment (P < 0.05); TG, TC, and LDL-C decreased (P < 0.01, P < 0.05), and HDL-C increased (P < 0.05) at month 3 after second treatment. Compared with the control group at month 3 after second treatment, TG, TC, and LDL-C all decreased, and HDL-C increased in the treatment group (all P < 0.05).

Idiosyncratic adverse drug reactions (IDR) induce severe medical complications or even death in patients. Alert structure in drugs can be metabolized as reactive metabolite (RM) in the bodies, which is one of the major factors to induce IDR. Structure modification and avoidance of alert structure in the drug candidates is an efficient method for reducing toxicity risks in drug design. This review briefly summarized the recent development of the methodologies for structure optimization strategy to reduce the toxicity risks of drug candidates. These methods include blocking metabolic site, altering metabolic pathway, reducing activity, bioisosterism, and prodrug.
