microRNAs are a class of highly conserved small non-coding RNAs with single-strand,which regulate their target mRNAs at post-transcriptional level.They have been shown to play an important role in the regulation of development of hemopoietic system malignancies.Evading apoptosis is a hallmark of tumorigenesis.In recent years,accumulative data have proved that aberrant expression of microRNAs participates in the regulation of many crucial pathways of apoptosis.By binding to their target mRNAs,microRNAs may inhibit apoptosis (e.g.miR-17-92 cluster,miR-21) or promote apoptosis (e.g.miR-15a/16-1,miR-150),which act as oncogene or tumor suppressor.In addition,the differential expression of microRNAs in lymphoma may provide new markers in determination of prognostic factors.Moreover,insights into microRNA expression in lymphoma may reveal potentially novel therapeutic targets.

Objective To study the influence of HBV infection for gastromucous membrane in chronic hepatitis B and cirrhosis and its pathogenesis.Methods The liver biopsy,gastroscope,liver function and HBVM were detected at the same time in 60 patients with chronic hepatitis B and cirrhosis.HBsAg and HBcAg in the tissues of liver and gastromucous membrane were detected by SP immunohistochemistry.Results The damage of gastromucous membrane were found in 56 of 60 patients.Its damage degree was showed as moderate and severe.The other 34 showed mild and moderate damage(P

The several questions in Theories of Acupuncture and Moxibustion of Different Schools, "the twelfth five-year plan" teaching material, are analyzed and discussed. The expression of DOU Han-qing on "playing a role of meridians, collaterals, qi and blood" is not so accurate, which is suggested to modify as "attaching the importance to needles". "Theory of heaven, human being and earth" "theory of acupuncture on qi regulation" and "the eight therapeutic methods in treatment of disease" in Jinzhenfu (Ode to Golden Needles) are valuable academically and suggested to be supplemented. The expression of XI Hong on "reinforcing and reducing technique by following or against the running course of meridian" and the expression of XU Feng on "the magic turtle eight techniques" are not concrete. It is required to elaborate them in detail. These questions are put forward and needed to discuss with the editors so as to perfect the teaching material.

OBJECTIVETo explore the expression of the epithelial cell adhesion molecule (EpCAM) in prostate cancer (PCa) and its clinical significance.

METHODSWe collected tissue samples from 63 cases of PCa, 46 cases of prostatic intraepithelial neoplasia (PIN), and 58 cases of benign prostatic hyperplasia (BPH) adjacent to PCa and determined the expression of EpCAM in the epithelial and stromal cells by immunohistochemistry.

RESULTSThe positive expression rates of EpCAM in the epithelial cells were significantly higher in PCa and PIN than in PCa-adjacent BPH (98. 4 and 97. 8 vs 51.7%, P <0. 01), and so was that in the stromal cells of PCa than in those of PCa-adjacent PIN (89.5 vs 50.0%, P <0.01). The expression of EpCAM.was remarkably higher in the stromal cells of bone metastasis than in those of non-bone metastasis tissue (100. 0 vs 40. 0%, P <0. 01) but showed no statistically significant differences between the highly and poorly differentiated PCa tissues (88.5 vs 91.9%, P >0.05).

CONCLUSIONThe expression level of EpCAM in the stromal cells of PCa is related to the occurrence, progression, and bone metastasis of the tumor, and therefore may be used as a marker in the early diagnosis of PCa as well as a predictor of bone metastasis of the tumor.

Objective To know the effects of air pollution on the activity of aryl hydrocarbon hydroxylase (AHH) in the placenta tissue of women in Taiyuan, Shanxi Province. Methods The decrement of BaP after the metabolic procedure was used as the indicator of AHH activity. 151 lying-in women were selected and the AHH activity in the placenta was determined by fluorescence spectrophotometer, the precooling EDTA was added in the determination to inactivate AHH and to stop the reaction completely in order to get more stable result. Results The AHH activity in the placenta tissue increased as the atmospheric particle concentration and the BaP concentration in the particles increased. Conclusion The air pollution may induce the AHH activity increase in the placenta tissue of pregnant women in Taiyuan. The AHH activity can be used as the biological monitoring indicator in the PAHs polluted areas.

Objective To study the relation between copper,copper-zinc ratio in blood and blood-fat only in the copper intake lower than the normal acceptable daily intake,and to provide a unified dosage evidence for copper multi-ways exposure.Methods Forty-two SD rats were divided into 7 groups randomly.The rats in one group among them as the normal control group were fed on the normal fodder and water,the other 6 groups were fed on special fodder without copper and deionized water and i.g.copper gluconate at doses of 0ADI(the acceptable daily intake of rat),1/625ADI(0.000 128 mg/ml),1/125ADI(0.000 64 mg/ml),1/25ADI(0.003 2 mg/ml),1/5ADI(0.016 mg/ml) and ADI(0.8 mg/ml),for 30 days.The activity of ceruloplasmin(CP),the content of copper,zinc in the blood and the level of total cholesterol(TC),triglyceride(TG),high-density lipoprotein(HDL) and low density-lipoprotein(LDL) were determined.Results In the case of copper intake lower than the normal acceptable daily intake,the activity of CP in the blood of all treated rats were lower than the normal level(P

Objective To construct a cDNA library from Hepialus armoricanus parasitized by Cordyceps sinensi. Methods Total RNA was extracted from Hepialus armoricanus parasitized by Cordyceps sinensi and mRNA was purified, cDNA was synthesized by reverse transcription, and cDNA fragments larger than 1kb were ligated with dephosphorylated arms of pBluescriptⅡ SK(+) XR vectors. The recombinant vectors were eletroporated into DH10B.The size of cDNA inserts and the diversity of library were detected by PCR. Results The cDNA library of stroma contained 1.28?106 recombine clone,that of mycelium was 1.0?106 recombine clone. The rate of recombination of stroma was 87.5%,that of mycelium was 68.75%. The insert size ranged from 0.5 to 2 kb. Conclusion The cDNA library Hepialus armoricanus parasitized by Cordyceps sinensi has been constructed successfully.
