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.

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.

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

Objective To explore the current situation of nursing students' leadership,in order to improve the clinical leadership of nursing students and provide reference for nursing teaching.Methods In July 2016,a questionnaire survey of nursing students including undergraduate and junior college students in our hospital was conducted by using the Self Assessment Leadership Instrument.SPSS 17.0 was used to conduct the t test to investigate the nursing leadership differences between the two groups.Results The total score of nursing students was (114.68 ± 18.25),and the score of undergraduate students was higher than junior college students (t=8.13,P=0.000);In the dimensions of critical thinking,decision-making skill,interpersonal relationship,team spirit and working relationship,there were significant differences in the scores of undergraduate and junior college students with different levels of education (P＜0.05).Conclusion The level of leadership of nursing students is low.In the process of nursing students' education,we should carry out the leadership courses in the school and practice leadership in clinical clerkship,so that we can promote the improvement of nurses' leadership and promote the development of nursing science.

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 explore the central mechanism of working memory impairments experienced by patients with schizophrenia.Methods:Using block-design,ten normal and twenty patients with schizophrenia perform digital recognition(remember two or five digitals simultaneous and make judgment about whether the digital presented latter is that appeared before)and direction judgment of arrows(toward to left or right)while proceeding blood-oxygen level dependent contrast functional magnetic resonance imaging(BOLD-fMRI).Results:On the condition of same cognitive load,abnormal activation of basal ganglia occurred in schizophrenics.Comparing to normal control,patients with schizophrenia exhibited a tendency of more activation in dorsolateral prefrontal cortex.Conclusion:Abnormal activity of basal ganglia and dorsolateral prefrontal cortex may be the critical cause of working memory deficit experienced by patients with schizophrenia.

Objective:To analyze the manifestation and essence of the knowledge of Chinese animal zodiacs in normal and cognitive impaired Chinese elders by Animal Fluency Test (AFT).Methods:512 normal elders, 153 patients with amnesic mild cognitive impairment (aMCI) and 124 patients with Alzheimer disease (AD) were evaluated with AFT and other tests (the mini-mental state examination, auditory verbal memory test, etc).Results:AFT total correct numbers and non-zodiac-animal numbers rather than zodiac-animal numbers showed significant relationships with gender, education level, premorbid ability, general cognitive and memory functions (r=-0.107~0.311,P

Objective To Observe the effects of tumor necrosis factor ? (TNF ?) on cell proliferation and Intracellular free calcium concentraction ([Ca 2+ ]i) in endothelium of human umbilical vein endothelial cells (HUVEC) and investigate the pathogenesis of pregnancy induced hypertension syndrome (PIH). Methods Confluent monolayer of HUVEC was directly incubated with TNF ? at following final concentrations: 500, 1 000, 2 000 U/ml for 24 hours. The percentages of different cellcycles and [Ca 2+ ]i were measured by flow cytometry and fluorospectrophotometry. Results Incubated with TNF ?, the endothelial cells were elongated and transformed into fibroblast like cells. Border of nucleus was sharp, clarity, and cells were in regular shape. But there were abnormal granules in cytoplasma and some cells detached at the concentrotion of 2 000 U/ml of TNF ?. Stimulated by TNF ?, the percentage of cellcycles from phase G 0+G 1 to S and G 2+M decreased significantly and it was dose dependent. [Ca 2+ ]i increased significantly and dose dependent as well. Conclusion TNF ? may injure endothelium directly and inhibit its proliferation and repair through the changes of [Ca 2+ ]i level. It may play an important role in the pathogenesis of PIH.
