1.The in vitro HAART pharmacodynamics study with dolutegravir as the "anchor".
Acta Pharmaceutica Sinica 2015;50(1):50-58
This study is to evaluate the HAART pharmacodynamics with dolutegravir as the "anchor" in vitro. A nucleoside reverse transcriptase inhibitors (NRTIs) resistant recombinant virus model (VSVG/HIV-1(RT-D67N,K70R,T215F)) and an integrase inhibitors (INIs) resistant recombinant virus model (VSVG/HIV-1(IN-G140S,QI48H)) were constructed and established. The anti-viral pharmacodynamics was evaluated with drug combinations including two NRTIs along with one INI or one NNRTI. The results showed that the combination with an INI gave a stronger synergism on wild type HIV-1 replication comparing to that with an NNRTI. Comparing the two INIs as the "anchor" for HAART, DTG exhibited an equivalent CI to that of RAL on wild type HIV-1 replication; but a greater synergy than RAL on INI-resistant HIV-1 replication. Besides of the pharmacodynamics results of DTG-based drug combination, the results may contribute to clinical antiviral therapy.

4.Meta-analysis of studies on inhaled corticosteroids and montelukast in children with asthma
Chongqing Medicine 2014;(21):2730-2733
Objective To compare the effect of inhaled corticosteroids and montelukast in children with asthma .Methods Data were obtained from Pubmed ,Embase and Central databases ,CNKI and VIP .Only randomized controlled trials (RCT ) that evalua-ting inhaled corticosteroids and montelukast for children were included .The Cochrane collaboration risk bias tools was used to eval-uated the quality of literature .Results The patients with inhaled corticosteroids had a better effect in FEV 1% and PEF than pa-tients with montelukast ,the incidences of adverse drug reactions had no statistically significant difference .The patients with inhaled corticosteroids combined with montelukast had a better effect in FEV 1% or PEF than patients with inhaled corticosteroids only . Conclusion The effect of inhaled corticosteroids is better than montelukast ,the effect of inhaled corticosteroids combined with montelukast is better than inhaled corticosteroids only ,and has drug safety .

Objective To investigate the effect of fluoride on expression of Runx2 mRNA and protein in bone tissue of rats. Methods Fourteen SD rats were randomly divided into two groups: control group(tap water with fluoride < 0.06 mg/L), and fluorosis group(fluoride 50 mg/L in water). After 4 moths, expressions of both mRNA and protein of Runx2 in rat bone tissue were determined by RT-PCR and Western blotting. Results The results showed that the expression of Runx2 mRNA and protein in fluoride-treated bone tissue were 2.287 ± 0.261 and 0.929 ± 0.229, respectively, both of which were significantly higher than those of control group(0.995 ± 0.123,0.317 ± 0.068, t = 11.85,6.78, P < 0.05). Conclusions Fluoride can increase the expression of Runx2 mRNA and protein in bone tissue of rats, and Runx2 may be involved in the pathogenesis of bone injury caused by fluoride.

Objective To investigate the value of the combined detection of serum human epididymal secretory protein 4(HE4) and carbohydrate antigen 125(CA125) in diagnosing ovarian and uterine tumor .Methods Serum levels of HE4 and CA125 were detected in 112 cases of ovarian cancer ,92 cases of uterine cancer ,145 cases of ovarian benign diseases ,138 cases of uterine adeno-myoma and 56 cases of healthy controls by ELISA and electrochemiluminescence(ECL) immunoassay respectively .Results Serum levels of HE4 and CA125 were (246 .80 ± 52 .81)pmol/L and (439 .20 ± 305 .80)U/L in the ovarian malignant tumor group , (196 .50 ± 38 .15)pmol/L and (463 .80 ± 127 .60) U/mL in the uterine malignant tumor group and (19 .76 ± 16 .45)pmol/L and (15 .67 ± 11 .19)U/mL in the control group ,the differences had statistical significance (P<0 .05) .Serum levels of HE4 and CA125 before operation and in postoperative 2 weeks in the ovarian cancer group and the uterine cancer group had statistical difference (P<0 .05) .Conclusion The combination detection of serum HE4 and CA125 can improve the accuracy and sensitivity in the diag-nosis of pelvic tumors .

[ Objective]Quantitative characteristics of tongue color is investigated by colorimetrical method to supply evidence for the objectivity of tongue inspection. [Methods] Two hundred and seven tongue pictures with different tongue color were scanned. The values of R (red) , G (green) and B (blue) of different sampling spots in the pictures, as well as their ratios with the total value of R + G + B were observed. Purple-bluish tongue was clustered with the above indexes and then was compared with other common-colored tongue color. [Results] In light white tongue, G ratio was high, R ratio and B ratio low; in red tongue, R ratio was high, G ratio and B ratio low; in purple-bluish tongue, B ratio was higher, G ratio high and R ratio low. The total value of R + G + B was higher in light white tongue, high in purple-bluish tongue and low in red tongue. [Conclusion] There are colorimetrical characteristics in tongue pictures from different monographs of traditional Chinese medicine, but the colorimetric parameters of the tongue pictures should be applied according to clinical cases.
