1.Roles of the liver regeneration phosphatase-3 and its inhibitors in tumor
Journal of International Oncology 2012;39(6):415-417
Phosphatase of regenerating liver-3 (PRL-3) is a novel small molecule protein-tyrosine-phosphatase,which plays an important role in the oncogenesis and deveopment of tumors.Studies show that PRL-3 regulates neoplasm progress through participating in multiple signal pathways.Its high expression can significantly promote neoplasm metastasis in cancer tissue.However,there is no expression of PRL-3 in most normal tissue.PRL-3 is expected to be a potential tumor maker of diagnosis and a new target for the therapy of cancer.

BACKGROUND: With the rapid development of modern society, psychological problems in college students have been paid high attention by educatienal organizations of psychological health in China. OBJECTIVE: To probe into the influencing factors of psychological problems in college students. DESIGH: Cluster sampling 1∶2 paired observation, case-control study. SETTING: Medical College of Wuhan Polytechnic University. PARTICTPANTS: 1 200 sophomores with the age ranged 19-20 years were selected from Wuhan Polytecnic University by cluster sampling at June 2001, and 145 students with the scores of more than 3 factors greater than 3 points were screened by Symptom Checklist 90 (SCL-90) (including 9 factors of somatization, compulsion, interpersonal sensitivity, depression, anxiety, hostility, phobia, paranoid and schizophrenia. The higher the grade was, the severer the symptom was) to be the psychological problem group. Subjects were selected to be the normal controls at the ratio of 1∶2 with those in the psychological problem group, whose classes, specialties and ages (the difference was less than 2 years) were similar to those of the enrolled patients. 290 students normal in the indexes of SCL-90 were taken as the matched group. Of all subjects in both experiment groups, there were 173 males and 262 females with an average age of 19.2 years. METHODS: ① The subjects in the two experiment groups were investigated of the psychological health by SCL-90 as well as the personality characteristics and Eysenck Personality Questionnaire (EPQ) (For Adult). The EPQ statistic software designed by the Institute for Juvenile and Children, Tongji Medical College of Huazhong University of Science and Technology was adopted to acquire the E score (introversion, extroversion), N score (nervousness), P score (psychoticism), L score (conceal) and quantity form quadrant of E-N coordinate picture, so as to define the tendencies of characters. ② The psychological problem was considered to be the dependent variable, while all relevant factors (The influencing factors of psychological problem included the understanding from parents, relationship with family members, desire for learning, personality characteristics, over-high P score, over-high/low E score, over-high/low N score) were taken as the independent variable. Single-factor Logistic regression analysis was conducted at 1:2. ③ Based on 1:2 single-factor Logistic regression analysis, the variances were selected from factors of P < 0.01 together with the Logistic regression models of multifactor at 1:2 by stepwise regression method.MAIN OUTCOME MEASURES: ① Comparison in the SCL-90 score between the psychological problem group and the normai control group. ② Single-factor and multivariate analysis of the relevant factors of psychological problems. RESULTS: A total of 435 enrolled students were involved in the analysis of results. ① The average score of somatization, compulsion, interpersonal sensitivity, depression, anxiety, hostility, phobia, paranoid and schizophrenia in students of the psychological problem group was higher than that in the normal control group (t=-13.39, 29.64, 27.09, 26.04, 19.52, 18.13, 14.15, 18.61, 22.41, P< 0.01). ② Nine factors were selected in the single factor analysis after the Logistic regression analysis, including 6 protective factors of understanding from parents, relationship with family members, desire for learning, personality characteristics, E > 61.5, N < 38.5, while he other 3 factors (P > 61.5, E < 38.5, N > 61.5) were risk factors. The multivariate analysis showed that factors of relationship with family members, desire for learning as well as personality characteristics were protective factors, while it was a risk factor when N > 61.5.CONCLUSION: The psychological problems in college students relate to the relationship with family members,understanding from the parents, desire for learning as well as the character trait and personality characteristics.

Objective To analyze the current clinic application of severe acne treatment, and to provide evidences to improve its treatment. Methods Using sampling survey, a total of 3 012 severe acne patients who visited the dermato-logical department of 35 hospitals over the country for the first time were selected for this study. Each patient filled a ques-tionnaire about their acknowledgement, history of medical intervention and drug therapy of severe acne. Results Among all 3 012 patients with severe acne, 76.6%believed acne is a kind of skin disease, but only 35.2%of the patients went to see doctors at early stage of disease, while others choose interventions such as self-extrudation , topical medication or skin care products, herbal tea/folk recipes, beauty salons and application of coverture cosmetics. Among all severe acne patients, 2 388 cases (79.3%)had taken oral medications, which included 1 161(48.6%) patients who took anti-biotics. 394 cases (33.9%) took roxithromycine and 173 cases(14.9%) took other kinds of anti-biotics. 55.5%of all these patients who took oral medication less than 4 weeks in duration. 2 081 cases (69.1%) applied external drugs, in which includes 90 cases (4.3%) of using glucocorticoid, and 437 cases (21.0%) of using other kinds of external products. The adverse effects of topical treat-ments were commonly observed, such as erythema (512 cases, 24.6%), desquamation (683 cases, 32.8%), scab (73 cases, 3.5%) and hypersensitive (281 cases, 13.5%). Conclusion Severe acne is a disease need systematic treatment. but only mi-nority of the patients went to see doctors at early stage of disease. The current problems in treatment of severe acne include lack of target in choosing drugs, not long enough treatment course, and adverse effects of cutaneous administration.Early , safe and targeted medical attention with sufficient treatment course is encouraged.

To investigate whether the Bcl-2 gene family is involved in modulating mechanism of apoptosis and change of cell cycle protein induced by curcumin in acute myeloid leukemia HL-60 cell line and primary acute myelogenous leukemic cells, the Bcl-2 family member Mcl-1, Bax and Bak and cell cycle proteins including P27kipl, P21wafl, cyclin D3 and pRbp- were selected and their expression detected by SABC immuno-histochemical stain method. The attitude of sub-G1 peak in DNA histogram was determined by FCM. The TUNEL positive cell percentage was identified by terminal deoxynucleotidyl transferase (TdT)-mediated Biotin dUNP end labeling technique. It was found that when HL-60 cells were treated with 25 mumol/L curcumin for 24 h, the expression level of Mcl-1 was down-regulated, but that of Bax and Bak up-regulated time-dependently. There was significant difference in the expression level of Mcl-1, Bax and Bak between the curcumin-treated groups and control group (P < 0.05-0.01). At the same time, curcumin had no effect on progress of cell cycle in primaty acute myelogenous leukemia at newly diagnosis, but could increase the peak of Sub-G1 (P < 0.05), and down-regulate the expression of Mcl-1 and up-regulate the expression of Bax and Bak with the difference being statistically significant. The expression of P27kipl, P21wafl and pRbp- were elevated and that of cyclin D3 decreased in the presence of curcumin. These findings suggested that the Bcl-2 gene family indeed participated in the regulatory process of apoptosis induced by curcumin in HL-60 cells and AML cells. Curcumin can induce apoptosis of primary acute myelogenous leukemic cells and disturb cell cycle progression of HL-60 cells. The mechanism appeared to be mediated by perturbing G0/G1 phases checkpoints which associated with up-regulation of P27kipl, P21wafl and pRbp- expression, and down-regulation of cyclin D3.
