Objective To study the mechanism of interferon-γ(IFN-γ)on the intervention of renal carcinoma cell proliferation.Methods Using concentration of 1 000,2 000,3 000 U/mL IFN-γtreatment of renal cell carcinoma 786-0 cell line,in 24 hours,48 hours,72 hours after treatment,the inhibition rate of cell proliferation was determined with CCK-8 method,using flow cytometric analysis of cell cycle,using RT-PCR for detection of hepaCAM mRNA,and using the Western boltting method for detection of MAD1 protein expression.Results Different concentrations of IFN-γhad the inhibitory effects on renal cell carcinoma cell proliferation,the concentration of the inhibitory rate of 72 hoursand 48 hours more than 24 hours,the difference was statistically significant (P<0.05);at the same time,a higher IFN-γconcentration,the inhibition rate was greater,the difference was statistically significant (P<0.05 );the cell cycle distribution results showed,the experimental group of renal carcinoma cells proliferation in the treatment of abnormal G0/G1 phase after 48 hours;and the control group (39.89 )compared with the experimental group,the proliferation index (25.65 )decreased significantly,the difference was statistically significant (P<0.05 );results showed that,the experimental group in renal cell carcinoma cells after 48 h of treatment,compared with control group,hepaCNM mRNA,MAD1 protein expression increased obviously,the difference was statistically significant (P<0.05 ).Conclusion IFN-γcould increase the expression of MAD1 by promoting hepaCAM expression,inhibits renal carcinoma cell proliferation.

OBJECTIVE: To observe the time-course expression of zonula occludens-1 (ZO-1) in cerebral cortex after traumatic brain injury (TBI). METHODS: The TBI model of mouse was established. The mice were divided in 1 h, 3 h, 6 h, 12 h, 24 h, 3 d, 7 d after TBI, sham and control groups. The permeability of the blood brain barrier was evaluated by measuring the extravasation of Evans blue (EB) dye. The expression of ZO-1 in cerebral cortex in the injured area was detected by Western blotting and immunohistochemistry. RESULTS: The extravasation of EB dye of injured cortex gradually increased from 1 h, peaked at 1-3 d and approximately decreased to normal at 7 d after TBI. Western blotting revealed that the expression of ZO-1 gradually decreased after 1 h, was at the lowest at 1-3 d, and then significantly increased after 7 d but was still lower than that of normal and sham groups. The result of immunohistochemistry showed that ZO-1 had strong expression in vessel of normal cortex, gradually decreased after TBI, and almost disappeared at 3 d after TBI and gradually recovered to normal level later. CONCLUSION The expression of ZO-1 in the injured cortex after TBI initially decreases and then increases. The negative correlation between ZO-1 expression and EB extravasation after TBI could be used as a new indicator for wound age estimation.

Karoshi remains one of the most troublesome issues in forensic identification. It is rather a social medicine than a clinical disease. Japanese scholars pioneered examining the relation between sud- den cardiac death (SCD) and chronic fatigue from long time and/or high-tension work. In the current case, a 55-year-old man, whose job was loading and carrying heavy cement bags, was found dead after 11 days of continuous hard work. His family members sued the cement factory for his death and claimed for compensation. The problem was the difficulty of identifying the causative relation without the precedent or the relevant regulations. However, the forensic problems were finally acknowledged after autopsy and calculation of labor intensity. The lawsuit was won as the first case pertaining to Karoshi in the Chinese court.

The systematic position of Fritillaria hupehensis has been in dispute. Phylogentic analyses were conducted on sequences of ITS, rpl16, matK sequences for species of F. hupehensis and allies. Lilium davidii was designed as outgroup. The analyses were performed using MP and ML methods. Conclusions could be achieved as follow. The topologies of MP and ML are consistent. The samples of F. hepehensis from different places form a supported clade with a strong bootstrap. And then form a strongly supported clade with F. anhuiensis, F. monantha. The results suggests that although F. hupehensis has a closet relation with the two ones, it exists some difference.

The paper is aimed to study the difference in yield and quality at different harvest time and determine the optimum harvest of planting Gentiana in Ludian traditional harvest period. The authors analyzed the variation in fresh weight, dry weight, dry discount rate, length, diameter, volume and the content of gentiopicroside, loganin acid, alcohol-soluble extract and total ash and made a comprehensive appraisal of yield, appearance quality and intrinsic quality by gray relational distance ideal Comprehensive Evaluation method. The results showed that there is a big difference in yield and quality both 2-year-old and 3-year-old Gentiana harvested in traditional harvest period and the comprehensive evaluation more better when harvested more later. It can be seen, Gentiana harvested the later had a better yield and quality in Ludian traditional harvest period. The harvest of Gentiana can be appropriate delayed depending on the particular circumstances of production.
