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.

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 .

The incidence of severe acute pancreatitis in children is lower.But it has abrupt onset and atypical symptoms.The fatality rate is relatively high.This paper will review the progress on the diagnosis and treatment of severe acute pancreatitis.

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.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common disease in males, which is characterized by persistent discomfort or pain in the pelvic region. As currently used drug therapies fail to produce satisfactory results, it is an urgent task to find new and effective methods for the treatment of CP/CPPS. In recent years, many reports are seen on the extracorporeal shock wave therapy (ESWT) for CP/CPPS. ESWT can significantly improve the symptoms of pelvic pain and urination disorders in CPPS patients, and its therapeutic effect is attributed to the improvement of angiogenesis and block of pain nerves.

[ 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.
