Objective: To explore the mediation of stress between perfectionism and life satisfaction.Methods: 317 college students were surveyed with questionnaires.The data were analyzed by hierarchical regression.Results: ①Regarding general perfectionism,both male and female students' stress fully mediated negative perfectionism and life satisfaction but did not mediate positive perfectionism and life satisfaction;②Regarding domain-specific perfectionism,male students' appearance stress fully mediated related perfectionism and satisfaction,but for female students its mediation was partial.Both male and female students' personality stress fully mediated personality perfectionism and satisfaction.Mediation models involved academic,love,interpersonal relationship perfectionism and their related satisfaction were not found.Conclusion: The mediations of stress between perfectionism and life satisfaction are different in different life domains.

Objective To investigate the role of HMGA2 expression and epithelial to mesenchymal cell transformation in the regulation of TGF -β1 in human gastric cancer cells .Methods Human gastric cancer cell SGC-7901 was treated by TGF-β1 at different time points(0,3,6,24,48,72 h).We observed the changes in cell morphology of SGC-7901 through the microscope;HMGA2 assay,E-cadherin,Vimentin protein expression wereperformedbyWesternblot;cellinvasioncapabilitywasanalyzedbytranswellchamberassay.Results (1) With the prolonged duration of action of TGF -β1,SGC-7901 changes in cell morphology ,cells gradually be-came longer and larger.(2)In the role of TGF-β1,gastric cancer cells SGC -7901 are varying degrees of HM-GA2 expression and E -cadherin、Vimentin.HMGA2 protein begun to express from 0h to 6hrs.and HMGA2 pro-tein became the strongest at 6hrs and decreased slightly from 24hrs.E-cad protein expression at 0h begun at 3hrs highest expression ,and the reduction started from 3hrs.Vimentin protein was the highest at 48hrs then gradu-ally decreased.Conclusion In the TGF-β1 induced the process of epithelial to mesenchymal cell transforma-tion in gastric cancer cells SGC -7901 ,HMGA2 protein play an important role .HMGA2 can be used as snail pro-moter,combined with Smads ,promotes the process of epithelial -mesenchymal transformation .HMGA2 may also be regulated by Wnt /β-Catenin signaling pathway on growth and apoptosis of tumor cells .

Tumor metastasis and invasion of cancer are the leading causes of death in patients .The processes of tumor metastasis and invasion involves a variety of factors in which epithelial -to-myofibroblast transition( EMT) plays an important role .Transcription factor Snail as EMT of tumor cell key regulator has played an important role .Through the study of Snail regulating EMT of tumor cell signaling pathways will help us under -stand the mechanisms of tumor invasion and metastasis better and provide a basis for finding effective targets .

This study reviews the researches on self-handicapping in about more than 20 years. It summarizes the practical researches of self-handicapping from 7 aspects: (1)manifestations and types of self-handicapping behaviors;(2)evaluative conditions that typically elicit self-handicapping;(3)motives underlying self-handicapping; (4)factors influencing on self-handicapping; (5)consequences of self-handicapping; (6) measurements of self-handicapping. On this basis, it raises some questions in self-handicappping researches and points out the future direction.

OBJECTIVE: To investigate the tagging condition in medication of special population in package inserts in order to give reference for rational drug use of special population. METHODS: 389 pieces of common Chinese and western medicine package inserts of our inpatient and out-patient dispensaries were randomly collected and analyzed statistically in terms of the content of package inserts for special population, including pregnant and lactant women, children and the aged. RESULTS: A part of medication items of special population in package inserts had deficiency. According to the classification of dosage form, the tagging rate of injection exceeded other dosage forms reached to more than 90%, except of medication items for children. The tagging rate of oral formulation arrived at more than 90% only in terms of contraindications and cautions. According to the classification of manufacturer, the tagging rate of domestic drugs was kept at the low level while that of imported drugs exceeded 90%. CONCLUSIONS: Package inserts need to be improved with the effort of drug supervision management department, drug production department and population of using drugs to guarantee the safety of drug use in special population.

We obtained human IL-2R cDNA 673 bp fragments from plasmid pJSB15 and prepared ?-32 p-IL-2 R cDNA probe. Dot hybridizations of RNA extracted from human lymphocytes were done by using the probe. The results showed that PHA or TPA could induce IL-2 R mRNA, respectively; and the synergistic effects were seen when used them together. IL-2R mRNA could be expressed spontaneously in many kinds of leukemic lymphocytes isolated freshly from PBL of leukemic patients.

Objective To investigate the value of expressed prostatic secretion (EPS) leukocyte count in the diagnosis of chronic prostatitis. Methods EPS was obtained from 75 out patients with chronic prostatitis,pH and WBC per high power microscopic field being studied.Transabdominal prostatic ultrasonography was performed. Results Mean pH of the EPS was 6.9?0.4.pH of the EPS and the frequency of ultrasound abnomalities were significanly correlated to the leukocyte count in EPS.There was no correlation between age of symptom duration and the pH of EPS, frequency of ultrasound abnormalities or white blood cell counts in EPS. Conclusions In chronic prostatitis,the leukocyte count in EPS was positively correlated with the ultrasound abnomalities and the pH elevation of EPS.There was no correlation between age or symptom duration and pH of the EPS,frequency of ultrasound abnormalities or leukocyte count in the EPS.

Objective To investigate the value of procalcitonin in guiding the antibiotic use in acute exacerbation of chronic ob-structive pulmonary disease(AECOPD) .Methods A total of 184 patients with AECOPD in our hospital from March 2014 to Sep-tember 2015 were selected and divide into two groups by the random number table method .Ninety-two cases in the control group received the antibiotic therapy according to clinical experience .Ninety-two cases in the observation group was implemented the anti-biotic therapy according to serum procalcitonin level .Results Compared with before treatment ,the procalcitonin level after treat-ment in the observation group was decreased significantly (P<0 .05) .The procalcitonin level after treatment ,occurrence rate of a-cute exacerbation within six months and re-hospitalization rate within six months in the observation group were lower than those in the control group(P<0 .05) .The antibiotic use time ,antibiotic expenses ,hospitalization time and hospitalization cost in the obser-vation group were less than those in the control group(P<0 .05) .The total effective rate and hospitalization mortality rate had no statistical difference between the two groups (P>0 .05) .Conclusion Serum procalcitonin is significantly increased in the patients with AECOPD .Procalcitonin can be used for the optimized use of antibiotics .

Objective To investigate the MRI characteristics of the tumor of optic pathway and damage degree of visual function. Methods Analysis of 119 cases surgically and pathologically proved tumor suffering from optic pathway was carried out retrospectively. The patients included:36 ones with tumors in anterior segment of optic pathway,70 ones in middle segment of optic pathway,and 13 ones in posterior segment of optic pathway. The MRI examination series were transverse T 1WI SE,transverse and coronal T 2WI TSE,coronal T 2WI SPIR,and transverse,sagittal,coronal T 1WI SE after Gd DTPA enhancement. Results The tumors of optic pathway included:the primary tumors of the optic pathway and the tumors of any other part of the body which invaded the optic pathway. There was a special MRI feature on the each tumor suffering from optic pathway,but the pituitary adenoma which affects visual function was the most common tumor. Conclusion MRI is an effective method in the diagnosis of optic pathway tumor.
