The new HIV-1 NNRTI drug Etravirine (TMC125) and a promising drug candidate Rilpivirine (TMC278) in phase III clinical trial are compounds belonging to the diarylpyrimidine (DAPY) family. They are extremely high potent against both wild-type and many drug-resistant HIV-1 strains, providing new hope for HIV-infected patients who fail to use current drugs due to the emergence of drug-resistant HIV mutants. The discovery and development of DAPY derivatives as next-generation NNRTI drugs depend on multidisciplinary coordination and their success has encouraged new researches to explore more next-generation NNRTIs with new scaffolds. This review described the story of discovery and development of DAPY derivatives as next-generation NNRTIs and related progress.

Some conclusions drawn from explanatory randomized controlled trial (ERCT) lack practical value in application under real-world clinical settings, and there are also some limitations on the generalization of pragmatic randomized controlled trial (PRCT) results. In some countries, real-world studies (RWSs) have been conducted to explore the effectiveness and safety of clinical interventions or postmarketing drugs, which is a new tendency in clinical researches. By reviewing some RWSs carried out in Western countries, we sum up the basic characteristics of the research design, and discuss the differences and connections between PRCT and RWS. The design ideas of RWS are different from PRCT. Researchers in RWS tend to perform long-term evaluation based on large quantities of subjects and quite large sample and focus on outcome measures which are clinically meaningful. Strict control on data collection, management and analysis are very important to RWS and PRCT. Owing to the complexity of clinical interventions and evaluation, PRCT is not completely suitable for clinical researches in traditional Chinese medicine (TCM). It is an inevitable tendency to apply RWS in clinical trials of TCM. We can explore the efficacy of TCM interventions through PRCT, and better understand the effectiveness through RWS. RWS will become a powerful approach to TCM clinical trials and postmarketing evaluation of Chinese medicines.

Objective To study the standardization of similarity evaluation method of chromatographic fingerprints. Methods Computer simulation and HPLC method were used to investigate the characteristics of different similarity evaluation methods and the criteria of characteristic variables selection in chromatographic fingerprints. Results Cosine ratio and correlation coefficient should be the first choice for similarity calculation based on chromatographic peak area. Peak area is recommend to be used as the characteristic variable for chromatographic fingerprints. Conclusion The features of the commonly used chromatographic fingerprint evaluation methods are described and their range of application are defined.

Objective To study the correlation of TSH and the Heart-Qi Deficiency Syndrome (HQDS) in Coronary Heart Disease. Methods Plasma TSH level of patients with HQDS were measured with radioimmunoassy and were compared with that of N-HQDS group as well as normal control group. Results Plasma TSH has no significant difference among HQDS group, N-HQDS group and normal control group. Conclusion The level of plasma TSH was associated with coronary heart disease with HQDS.

Objective To study the value of echocardiography in the diagnosis of myocardial infarction(MI) and its complica tions.Methods The examination data in 140 cases of MI were collected from January 2012 to January 2016 and performed the analysis and comparison.Results In the ultrasound examination results in 140 cases,120 cases appeared varying degrees of segmental ventricular wall motion abnormalities,its diagnostic rate to MI was 85.71％,which of EKG was 78.57％,the MI detection rate of echocardiography and ECG combined examination was 90.71％,which was higher than that of single use of echocardiography or ECG.With the coronary angiogra-phy results as the control,the detection rate of echocardiography for the coronary arterial lesion sits was 82.86 ％.Among 140 cases of MI,22 cases of complications(15.71 ％) were de-tected out by echocardiography,including 7 cases of true ventricular aneurysm(5.00 ％),4 cases of left ventricular mural thrombosis(2.86 ％),1 case of ventricular septal perforation(0.71％) and 10 cases of ischemic mitral regurgitation(7.14％).Conclusion Echocardiography has higher accuracy in the MI diagnosis,com-bining with ECG can further improve the diagnostic rate.

Objective To investigate effect of emodin on mice immune function and its hemolysis toxicity.Methods The mouse specific immune cells of T, B lymphocytes and nonspecific immune cell of macrophages and NK cells were prepared and incubated in vitro.The different immune cells were treated by emodin with different concentrations of 5,10,15 and 20μM, and DMSO as control group.The effect of emodin on immune cells function was detected by neutral red assay and MTT assay.The hemolysis test in vitro was conducted by emodin with different concentrations of 20, 40, 60 and 80μM, physiological saline as blank control group and sterile distilled water as positive control group, then the hemolysis toxicity of emodin was observed. Results There were no significant difference of T and B lymphocyte proliferation among control group, 5, 10, 15 and 20 μM group(F=0.009,P=1.000;F=0.003,P=1.000), the phagocytic ability of macrophages enhanced in each dose group and was concentration dependent(F=665.525,P=0.000), the proliferation rate of macrophages enhanced and was concentration dependent(F=134.812,P=0.000), the activity of NK cells enhanced and was concentration dependent(F=200.190,P=0.000).Hemolysis test results showed the hemolysis rate was less than 5% in the range of 20 to 80μM emodin.Conclusion Emodin could significantly promote the nonspecific immune cells activity.Within the concentration of experiment, emodin has no hemolysis toxicity.

By means of global budget,the disease-specific scoring method was put in place for both settlement and payment in Huaian,Jiangsu province,for the purpose of cost control by the hospitals.This reform consists of total cost accounting,rational performance-based distribution system,multi-approached regulation of medical behaviors,and individual disease management to regulate medical behavior.These efforts aim at aligning with medical insurance payment reform,so as to improve hospital management,operation quality and socio-economic outcomes.Problems found in practice were also reviewed.

Objective To observe the acute side effects and recent therapeutical effect of cisplatinum/paclitaxe concurrent radiotherapy for patients with advanced nasopharyngeal carcinoma.Methods 87 patients with advanced nasopharygeal carcinoma were enrolled.According to the treatment,87 patients were divided into paclitaxe group (groupA,n =43) and cisplatinum group (group B,n =44).The two groups were treated with 6MV-X ray for radiotherapy.The prescription dose of radiation therapy was PGTV,PGTVnd 6 996 cGy/33F,PTV1 6 006 cGy/33F,PTV2 5 096 cGy/28F.The two groups began concurrent chemotherapy in radiotherapy,specific method:group A paclitaxe 30mg/m2,1 time a week,until the end of radiotherapy,group B cisplatinum 80 ～100 mg/m2,every 21 days.Results The recent therapeutical effect of nasopharyngeal lesions and lymph nodes of neck for group A and group B were 88.4％ and 86.4％ (x2 =0.079,P =0.778),88.4％ and 88.6％ (x2 =0.000,P =1.000),respectively.But the occurrence rate of group B ' oral mucosa reaction (x2 =4.295,P =0.038) and gastrointestinal reaction (x2 =4.482,P =0.028) were higher than that of group A.Conclusion Treated with cisplatin in advanced nasopharyngeal carcinoma after radical radiotherapy combined with docetaxel is similar,and the side effect is low,the tolerance of patients is good,curative effect is satisfied.

Cell cycle-related kinase (CCRK) as a novel CDK-activating kinase plays a significant role in cell cycle regulation.Related studies confirm that CCRK is overexpressed in various tumors,and is associated with poor prognosis of the patients,which indicates that CCRK takes part in the generation and development of the tumor.
