The standard treatment mode of locally advanced prostate cancer is still controversial.With the progress of medical technology,treatments of prostate cancer achieve different progresses in surgical treatment,radiotherapy and endocrine therapy.The three treatment modes have diverse tumor growth control rate and survival period,which have different complications and different influences on the quality of life.

This article mainly summarise the results of the chemical compositions and their pharmacological activities of Arnebiae Radix since 1966. The chemistry components isolated from Arnebiae Radix are mainly naphthoquinone, monoterpene phenol and quinone, phenolic acids and their salts, alkaloids, aliphatic and esters. Pharmacological results showed that the chemical compositions and the extracts of Arnebiae Radix have antibacterial, anti-inflammatory, anti-viral, hepatoprotection, antioxidant, anti-tumor and immune function and other activities. This article hopefully to provide a reference for further research, development and utilization of Arnebiae Radix.

Purple bacteria are extensively used in bacterial photosynthesis research. This review describes the structure of light-harvesting I, light-harvesting II and reaction center of photosynthetic apparatus of pur- ple bacteria and discusses the regulation mechanisms of photosynthesis (PS) gene transcription, with an emphasis laid on the transcriptional regulation of PS gene by PpsR/AppA system.

Twelve cases of Bartter's syndrome were reported and reviewed retrospectively.Usually vomiting was the first sympton in children,while fatigue was common in adults.Bartter's syndrome was characteristic of hypokalemia,metabolic alkalosis,elevations of plasma renin activity,serum angiotersinⅡand aldosterone and juxtaglomerular apperatus hyperplasia.Supplementation of potassium choloride was the main manner of therapy.

Background and Objective: The histone deacetylase inhibitor,trichostatin A(TSA),was shown to induce apoptosis in transformed cells at submicromolar concentrations. However, the effect of TSA on brain tumor cells is still unknown. This study was designed to investigate whether TSA posses antitumor activity and if any, its mechanism. Materials and Methods: A p53 mutant human glioma cell line T98G and a p53 wild type human neuroblastoma cell line SKNSH were exposed to TSA. Cell proliferation was assessed by sulforhodamine B (SRB) cytotoxicity assay. Apoptosis was quantified by flow cytometry and confirmed by apoptotic ladder formation. Expression patterns of accumulation of highly acetylated histone H3,H4; p53 and cell cycle-associated p21waf,p27 which were induced by TSA were determined by using Western blot analysis. Results: TSA inhibited the proliferation of brain tumor cell lines at nanomolar concentrations and induced accumulation of highly acetylased histone moleculars. Treatment with TSA at 0.33μ M for 24h significantly induced cell apoptosis.In addition to the suppression of cell growth, the up regulation of p21waf and p27 expression was observed within 48h after the treatment.p21 protein levels were increased at early time points and reached maximal levels at 8h, while p27 protein levels were increased after 8h. However, there was no significant changes of acetylased p53 and endogenous p53 protein levels were observed. Conclusion:TSA may inhibit brain tumor cell growth in vitro, which is otherwise particularly resistant to chemotherapy. TSA acts as an anti-tumor agent could be through co-operation between p21 and p27 in growth inhibition, irrespective of endogenous p53 status.

To explore the new method of discriminating Cistanche deserticola, Cynomorium songaricum and Orobanche pycnostachya by using PCR amplification of specific alleles. 30 samples of the different C. deserticola, 21 samples of C. songaricum and O. pycnostachya were collected. The total DNA of the samples were extracted, the ITS sequences from C. deserticola, C. songaricum and O. pycnostachya were amplified by PCR and sequenced unidirectionally. These sequences were aligned by using ClustulW. Specific primer was designed according to the ITS sequences of specific alleles, and PCR reaction system was optimized. Additionally, compare with the identification of specific PCR method and DNA sequence analysis method. The result showed that the 331 bp identification band for C. deserticola and the adulterants not amplified bands by a single PCR reaction, which showed good identification ability to the three species. PCR amplification of specific alleles can be used to identify C. deserticola, C. songaricum and O. pycnostachya successfully.

Eleven type 1 diabetic patients who received fixed regime of insulin Glargine were included in the study.The levels of fasting serum insulin were measured for each subject at 6:00 in three consecutive mornings.The variability of mean fasting serum insulin in each subject was 3.3%-41.5% (mean 15.4%).The variability did not correlate with the dose of Glargine statistically.

OBJECTIVE: To test droplet digital PCR for species identification and absolute quantification of biological sample. METHODS: Specific primers and probes for human mtDNA encoding gene ND4 and 16S rRNA were designed, and the species-specificity was assessed on DNA samples derived from human and common animals. To determine the sensitivity and stability of droplet digital PCR for species identification and absolute quantification, gradient dilution series of recombinant plasmid and 16 human DNA samples were analyzed. RESULTS: Human recombinant plasmid FAM (ND4) could be used in detecting the samples of human. And the results of detecting were consistent with all levels of diluted concentrations. Droplet digital PCR was able to detect low and single copy of target DNA. CONCLUSION Droplet digital PCR, with high sensitivity and specificity, is fully amenable for species identification and absolute quantification of biological samples, also it can be applied on routine forensic examination.
