Aim The effect of tetrandrine on TGF-?1 mRNA expression in glomerulosclerosis rat was observed. Methods The rats were randomly divided into four groups, such as the normal control group (sham operative rat), glomerulosclerosis model group,tetrandrine group and amlodipine group. The expression of TGF-?1 mRNA was analyzed by Northern blot hybridization. Results The expressions of TGF-?1 mRNA in two treating groups were much lower than untreated model group. There were no difference between these two treating groups. Conclusion Tetrandrine can decrease the expression of TGF-?1 mRNA in glomerulosclerosis rat induced by unilateral renctomy plus adriamycin.

Background:Microwave therapy is a minimal invasive procedure and has been employed in clinical practice for the treatment of various types of cancers.However,its therapeutic application in non-small-cell lung cancer and the underlying mechanism remains to be investigated.This study aimed to investigate its effect on Lewis lung carcinoma (LLC) tumor in vivo.Methods:Fifty LLC tumor-bearing C57BL/6 mice were adopted to assess the effect of microwave radiation on the growth and apoptosis of LLC tumor in vivo.These mice were randomly assigned to 10 groups with 5 mice in each group.Five groups were treated by single pulse microwave at different doses for different time,and the other five groups were radiated by multiple-pulse treatment of a single dose.Apoptosis of cancer cells was determined by terminal deoxynucleotidyl transferase dUTP nick-end labeling assay.Western blotting was applied to detect the expression of proteins.Results:Single pulse of microwave radiation for 5 min had little effect on the mice.Only 15-min microwave radiation at 30 mW/cm2 significantly increased the mice body temperature (2.20 ± 0.82)℃ as compared with the other groups (0.78 ± 0.29 ℃,1.24 ± 0.52 ℃,0.78 ± 0.42 ℃,respectively),but it did not affect the apoptosis of LLC tumor cells significantly.Continous microwave radiation exposure,single dose microwave radiation once per day for up to seven days,inhibited cell division and induced apoptosis of LLC tumor cells in a dose-and duration-dependent manner.It upregulated the protein levels of p53,Caspase 3,Bax and downregulated Bcl-2 protein.Conclusions:Multiple exposures of LLC-bearing mice to microwave radiation effectively induced tumor cell apoptosis at least partly by upregulating proapoptotic proteins and downregulating antiapoptotic proteins.Continuous radiation at low microwave intensity for a short time per day is promising in treating non-small-cell lung cancer.

There are few articles or reports collecting evidence about Kudiezi injection from premarketing and postmarketing research or studies systematically. This article is an exact miniature of a systematical report about Kudiezi injection. We analyzed information from four aspects, such as quality control reports, non-clinical premarketing safety experiments, postmarketing research (efficacy studies, hospital information system data and national spontaneous reporting system data), and literature analysis. All the four aspects build an evidence body for Kudiezi injection in order to inform its safety use in clinical practice and further study.

The endophytic bacteria of the mangroves were studied in this paper. The results show that there are 1.728 (0. 195 -4.225)?104cfu/g (fw) bacterial endophytes in the variety of mangroves, the most population of the endophytic bacteria was found in Rhizophora stylosa, the figure was4. 225?104cfu/g (fw) , the next was Bruguiera gymnorrhiza, Aegiceras corniculatum, Kandelia candel and Avicennia marina. In parts of the mangroves, the contents of the bacteria in stem was the most, the figure was 1. 649?10 cfu/g (fw) , then the root and the leaf. Of the bacteria, about 43. 53% strains expressed the antagonism against the growth of the plant pathogens, such as Fusarium oxyspontm f. sp. cubense , Colletotrichum sp. and Rahtonia solanaceance etc. and these bacteria were identified as Bacillus sp. . The results also showed that 9 of the 13 strains (69. 23% ) could promote the growth of the tomato, while 4 strains (30. 77% ) restrained the tomato's growth.

Genomic DNA of two fungi Thamnidium elegans and Umbelopsis isabellina were extracted with an amended Cetyltrimethyl Ammonium Bromide (CTAB) method. This modified method uses repeated freezing in liquid nitrogen and thawing with combination of shocking with glass beads to replace of the tra- ditional method. Quality and concentration of DNA extracted by the modified methodwere tested. Compared with the traditional method, higher yield and purity of genomic DNA were obtained with less amount ofmy- celium. The result indicted that this is a simple and highly efficient method, which is suitable to treat many samples at one time and for basic molecular experiments, such as restriction endonuclease reaction and PCR.

Objective To compare the effect of cimetidine associated with bletilla striata,rhubarb on peptic ulcer,cushingulcer,acute erosive gastritis,bleeding of esophagus and gastric funds varicosis of cirrhotic portal hyper- tension and gastri cancer.Methods 136 patients with upper gastrointestinal hemorrhage were randomly divided into 2 groups.The treated group(n=69)was given cimitidine associated with bletilla striata,rhubarb and the control group(n=67)was given cimitidine only.The effects of hemostasis in 2 groups were observed.Results The effect of hemostasis in the treated group was better than that in the control group on peptic ulcer,cushingulcer,acute ero- sive gastritis and gastric cancer(P＜0.05).There were no difference between 2 groups about bleeding of esophagus and gastric funds varicosis of cirrhotic portal hypertension(P＞0.05).Conclusion The effect of hemostasis on up- per gastrointestinal hemorrhage treated by integrated traditional Chinese medicine and western medicine might achieve better on cushingulcer,acute erosive gastritis,peptic ulcer and gastri cancer.It has less adverse effect and more safety.
