Wogonin is a kind of natural flavonoid compound. According to findings in the latest studies, wogonin shows a wide range of antitumor effects, with the characteristics of multi-pathway, multi-link and multi-target, such as promoting tumor cell apoptosis through ROS or Ca(2+)-mediated signal paths, enhancing tumor cytotoxicity by TNF-α and TRAIL, blocking tumor cell cycle, inhibiting tumor angiogenesis and resisting cancer synergistically with chemotherapeutic drugs. Moreover, Wogonin could enhance body immune function by enhancing immune cell infiltration, regulating the immune cell phenotype and promoting relevant cytokine secretion. In this paper, the authors summarized the advance in studies on wogonin's antitumor and immunomodulatory effects.

In order to solve the problems of erratic drug absorption and low bioavailability after oral administration for poorly-water soluble drugs due to low solubility, a series of novel pharmaceutical dosage forms as solid dispersion, liposome, microemulsion, vesicle, cyclodextrin inclusion complexes and drug nanocrystal have been developed in recent years. Among which drug nanocrystal attracts more attentions for its simpler preparation method, higher drug loading and easier manufacturing technology in the design of dosage forms suitable for different administration routes. In this paper, the nanocrystals of the poorly-water soluble drugs prepared based on bottom-up and top-down technologies were introduced. The characteristics and applications of the nanocrystal-based dosage forms as suspension, tablet and capsule were also introduced and carefully evaluated with the focus on their pharmacokinetics, pharmacodynamics and tissue targeted drug distribution after delivery by oral administration, intravenous injection and pulmonary inhalation. The advantages of drug nanocrystals in their therapeutics effects over the bulk drugs were discussed together with the inherent mechanism. Finally, the problems existing in basic research and scaled-up manufacture of drug nanocrystal as well as the possible ways of solution were listed out so as to make the nanocrystal-based preparations exert their maximum therapeutic effect after clinical application.

DNA damage response (DDR) in different cell cycle status of human peripheral blood lymphocytes (PBLs) and the role of H2AX in DDR were investigated. The PBLs were stimulated into cell cycle with phytohemagglutinin (PHA). The apoptotic ratio and the phosphorylation H2AX (S139) were flow cytometrically measured in resting and proliferating PBLs after treatment with camptothecin (CPT) or X-ray. The expressions of γH2AX, Bcl-2, caspase-3 and caspase-9 were detected by Western blotting. DDR in 293T cells was detected after H2AX was silenced by RNAi method. Our results showed that DNA double strand breaks (DSBs) were both induced in quiescent and proliferating PBLs after CPT or X-ray treatment. The phosphorylation of H2AX and apoptosis were more sensitive in proliferating PBLs compared with quiescent lymphocytes (P<0.05). The expression levels of anti-apoptotic proteins Bcl-2 were reduced and cleaved caspase-3 and caspase-9 were increased. No significant changes were observed in CPT-induced apoptosis in 293T cells between H2AX knocking down group and controls. It was concluded that proliferating PBLs were more vulnerable to DNA damage compared to non-stimulated lymphocytes and had higher apoptosis rates. γH2AX may only serve as a marker of DNA damage but exert no effect on apoptosis regulation.

Objective To understand the hypertension prevalence situation and its associated factors among residents in Hu‐bei Province to provide a reference basis for preventing and controlling residents′ hypertension .Methods The residents aged 15 years old or more were sampled from 20 counties (cities and districts) by adopting the multi‐staged stratified cluster sampling .The unified questionnaire was adopted to conduct the face to face interview by entering home .The multivariate Logistic regression was used to analyze the influencing factors of hypertension .Results A total of 28 555 respondents were investigated ,4 135 respondents reported hypertension and the hypertension prevalence rate was 14 .48% .The hypertension prevalence rate in urban residents was 18 .41% ,which was higher than 11 .71% in rural residents(P<0 .01) .The prevalence rates in males and females were 14 .10% and 14 .83% respectively ,showing no statistically significant difference between males and females (P>0 .05) .The multivariate Logistic regression results revealed that the risk of hypertension was increased with age ;compared with job‐hololers ,the retired(OR=1 .44 , 95% CI:1 .25-1 .65)and the unemployed(OR=1 .29 ,95% CI:1 .15-1 .46)had more possibility to suffer from hypertension ;higher income earners had lower risk of hypertension ;obese people(OR=3 .09 ,95% CI:2 .63~3 .63)and diabetes(OR= 3 .87 ,95% CI:3 .30-4 .52)were more likely to suffer from hypertension .Conclusion The prevalence rate of hypertension among residents aged 15 years old or more in Hubei Province presents the increasing trend ,which needs the corresponding departments and institutions to adopt the measures to actively prevent and control hypertension .

Objeetive To explore the effects of renal artery calcification on the progression of diabetic nephropathy (DN),the activation and its role of bone morphogenetic protein 2(BMP2) signal pathway in renal artery of rats.Methods Sixty male SD rats were randomly divided into control group(CON group),DN group and DN with vascular calcification group (DN+VDN group).Rats of group DN and DN + VDN were fed with high sugar and fat diet and injected with streptozocin (STZ) into abdominal cavity to induce diabetes.After diabetic models were successfully made,rats of group DN+ VDN were treated by vitamin D3 plus nicotine.The rats were sacrificed at 8th,12th and 16th week respectively and the levels of renal function,blood glucose and 24 h urinary protein (24-h Upro) were measured.The pathologic changes to the renal artery were observed by yon-Kossa staining and the calcium content was detected by calcium assay kit.The pathologic changes to the kidney were observed by HE.Immunohistochemistry was applied to detect the protein expression of BMP2/Smad1/Runx2/ Osterix signal pathway in the renal artery and real-time PCR were applied to detect the mRNA expression levels of BMP2 and Runx2.Results The calcium content and the deposition of black granules in DN group were significantly higher than those in group CON and lower than DN + VDN group at each time point (P ＜ 0.05).The renal function indices in group DN and group DN+VDN were gradually increased in 8th,12th and 16th weeks,and were higher than those in group CON (P ＜ 0.05).Compared with that in DN group,although the level of BUN,Scr,Cys C and 24-h Upro in DN+VDN group rats were higher at different time point,the level of Cys C at each time point and the level of 24-h Upro in the 16th week showed significant differences (P ＜ 0.05).The pathological damages of the kidney in group DN and DN+VDN showed a continual worsening trend and the pathological changes of the kidney in group DN+VDN were more serious than those in group DN.Furthermore,the levels of BMP2/Smad1/Runx2/Osterix signal protein and BMP2,Runx2 mRNA in DN rats were higher than those in CON group,lower than DN+VDN group at each time point (P ＜ 0.05).Correlation analysis demonstrated that calcium content was positively correlated with serum BUN,Scr,Cys C,24-h Upro and the expression of BMP2,Runx2 mRNA (r=0.835,0.705,0.829,0.897,0.641,0.683,P ＜ 0.01,respectively).Conclusion Renal artery calcification may participate in and promote the progression of DN,and the BMP2 signal pathway may be an important regulating factor in DN with renal artery calcification.
