Objective To observe the clinical efficacy and sperm density of Bushen Yijing decoction and tamoxifen,zinc and vitamin E in treating oligospermia with kidney deficiency syndrome .Methods 450 patients with oligospermia were randomly divided into 3 groups.150 patients of the treatment group were treated by Bushen Yijing decoction,tamoxifen,zinc and vitamin E,150 patients of the control group I were treated by Bushen Yijing decoction , zinc and vitamin E,150 patients of the control group II were treated by tamoxifen ,zinc and vitamin E.3 groups were treated for 3 months,pregnancy terminating of treatment and otherwise continued to observe for 3 months after the end of treatment,the sperm density and other sperm parameters (sperm amount,pH,sperm motility,sperm survival rate, sperm normal modality rate ) were evaluated before and after treatment .Results The total effective rates of the treat-ment group,control group I and II were 90.21%,85.11%,72.22%respectively.The total effective rate of the treat-ment group was higher than that of the control group I (χ2 =9.53,P<0.05) and II(χ2 =23.38,P<0.01).The pregnancy rates of the treatment group ,control group I and II were 42.66%,25.53%,20.83%,respectively.The pregnancy rate of treatment group was significantly better than that of the control group I (χ2 =9.26,P<0.01) and II (χ2 =15.78,P<0.01).There were significant differences between before and after treatment on sperm density , sperm motility,sperm survival rate and sperm normal modality rate in the treatment group ( t=-22.22,-18.07,-33.48,-28.46,all P<0.01).Conclusion Bushen Yijing decoction combined with tamoxifen ,zinc and vitamin E can evidently improve the sperm density and other sperm qualities and conception rate of oligospermia with kidney deficiency syndrome .

MicroRNAs (miRNAs) are small (approximately 22 nt) RNAs that exhibit a diversity in sequence,structure,abudance,and expression profile. Bioinformatic approaches and direct cloning methods have identified 3518 miRNAs from various species. MiRNAs play a pivotal role in the regulation of genes involved in diverse processes such as development,differentiation,and cellular growth control. Recently,many viral-encoded miRNAs have been discovered, most from the herpesviruses viral family. Virus-encoded miRNAs seem to evolve rapidly and regulate both the viral life cycle and the interaction between viruses and their hosts. The detailed study on the virus-encoded microRNAs and the role they play in the progress of viral infection,replication and expression will be beneficial to understand viral molecular biology,and also provide new strategies for the prevention and treatment of virus.

The oncogenic product of BCR-ABL is an abnormal tyrosine kinase that causes chronic myeloid leukemia (CML). With further research into the pathogenesis of CML, the discovery of compounds that selectively inhibit abnormal BCR-ABL tyrosine kinases is a research focus worthy of attention. The first three generations of BCR-ABL inhibitors are orthosteric inhibitors, which competitively block the binding of ABL protein tyrosine kinase to ATP and prevent it from activating downstream signals. The fourth-generation BCR-ABL inhibitors allosterically inhibit ABL protein tyrosine kinase by binding to the myristoyl pocket, providing greater selectivity and maintaining activity against drug-resistant mutations proteins. Novel drug design strategies such as proteolytic targeting chimera (PROTAC), covalent inhibitors and dual targeting inhibitors also provide new directions for the development of BCR-ABL kinase inhibitors. This paper reviews recent research advances on BCR-ABL kinase inhibitors and discusses drug design strategies for various novel BCR-ABL inhibitors.

Objective To investigate the effects of estrogen on mismatch repiar gene expression in colonic mucosa in vivo. Methods A total of 42 healthy individuals underwent colonoscopy were enrolled in the study. Half an hour before colonoscopy examination, blood sample was taken for determining the serum estradiol (E2) level. N ormal colonic mucosal tissues determined by naked eye under colonoscopy examination were taken in the right hemi colon to detect HMLH1 and hMSH2 gene expression by semi-quantitative RT-PCR and immunohistochemistry staining. Then the correlation of serum E2 levels with hMLH1 and hMSH2 expression in colonic mucosa was analyzed. Results A bimodal curve was presented for the correlation between serum E2 level in healthy individuals and hMLH1 expression in colonic mucosa. A strong positive correlation of E2 level with hMLH1 expression in normal colonic mucosa was observed when serum E2 level was more than 45 pg/ml (For mRNA, P=0. 003, r=0. 701; for immunohistochemistry positivity index, P=0. 000, r=0. 874).However there was no correlation between E2 level and hMSH2 expression. Conclusion High serum E2 level might increase the hMLH1 gene expression in colonic mucosa in vivo.
