BACKGROUND: Severe acute respiratory syndrome (SARS) is a kind of very strong infective respiratory system diseases. Due to rapid development of disease course, severe symptoms, forced isolation, being away the supports from relatives and friends, many patients with SARS presented extremely anxiety and panic, even depression and despair, and they are in the crisis state and need mental support and help.OBJECTIVE: To evaluate the therapeutic effect of mental crisis intervention in patients with SARS.DESIGN: Controlled observation.SETTING: Xiaotangshan Hospital of Chinese PLA.PARTICIPANTS: Totally 680 patients with SARS who received the mental intervention in the Psychological Counseling Center, Xiaotangshan Hospital of Chinese PLA in May 2003. The patients, 379 male (55.74%)and 301 female (44.26%), were aged (35±7) years. Degree of education:34.5% of patients received education below junior high school, 31.5% senior high school and 34.0% college. 100% of the patients had family member or colleague-infected life events, and 14.4% of the patients lost their family members. Degree of disease: 6.9% of patients were in the severe period, 67.5% in the stable period and 25.6% in the rehabilitation period.METHODS: ① Totally 489 patients who received telephone counseling,and attended telephone mutual-help group, group debugging, individual counseling and group counseling were chosen, serving as intervention group, and the other 191 patients served as control group. ②The mental health state of patients in the 2 groups was evaluated at admission with symptom checklist 90 (SCL-90), which consisted of somatization, obsessive compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation and psychoticism 9 factors. The grading scoring was used. The higher grades, the more severe symptoms. ③ The patients of intervention group were given comprehensive mental intervention, which included handing out materials(self-debugging propagandist manual), care from staff, mental counseling by telephone, group debugging, individual counseling, guidance by mental doctor, etc. Patients in the control group only received handed materials (self-debugging propagandist manual) and the care from staff. SCL-90 was used to re-evaluate the patients of intervention group and control group before discharge. ④Intervention therapeutic effect of patients in 2 groups were evaluated with comprehensive mental intervention questionnaires, which were mainly about self and social cognition, feeling and emotion, life behavior styles, physiological and body symptoms 4 dimensions. Grading scoring was used. The higher points, the better intervention effect. Self-rating and rating by others were used in each question. If the results in self-rating are the same as those in rating by others, questionnaire is valid, otherwise, it is invalid). ⑤ The scoring of all the patients at admission was compared with that of Beijing norm by using SCL-90.The mental health of patients of 2 groups after intervention was measured, evaluated and compared with SCL-90.MAIN OUTCOME MEASURES: Difference in scoring of SCL-90 between all the patients and Beijing norm; Changes in the scoring of SCL-90 between intervention group and control group at admission and after intervention.RESULTS: Totally 680 comprehensive mental intervention questionnaires were handed out, and 669 of them were retrieved, among which 483 from intervention group and 186 from control group. Altogether 669 patients participated in the result analysis. ① Points of each factor in SCL-90 of patients at admission were significantly higher than norm, especially in anxiety and phobic anxiety. 45.5% and 50.1% of the investigated patients had more than 3 points in anxiety and phobic anxiety respectively. 86.5% of the investigated patients had mental problems to different degrees. ②There was no significant difference in the points of various factors in SCL-90 at admission between intervention group and control group (P>0.05).In the various factors of SCL-90, no significant difference in the points of various factors in SCL-90 at admission between intervention group and control group (P>0.05).In the various factors of SCL-90,no significant difference exists in phobic anxiety and paranoid ideation and psychoticism between two groups (P>0.05),but the points of the other factors of intervention group were significantly lower than those of control group (P<0.05-0.01).CONCLUSION: Mental crisis intervention can remarkably lighten the somatization, obsessive-compulsive, anxiety and depression, lower interpersonal sensitivity and improve hostility.

OBJECTIVE:To observe the clinical efficacy and safety of ezetimibe combined with simvastatin in the treatment of membranous nephropathy complicated with hyperlipidemia. METHODS:90 patients with membranous nephropathy complicated with hyperlipidemia were randomly divided into observation group and control group,45 cases in each group. All patients received health guidance,low-fat diet,and the drugs without interfere with regulating lipid,hepatoprotective and lipid metabolism were for-bid. Control group was orally given 20 mg Simvastatin tablet,qd;observation group was additionally given 10 mg Ezetimibe tab-let,qd. They were treated for 8 weeks. Clinical efficacy was observed,lipid levels [total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C)],aspartate aminotransferase (AST),ala-nine aminotransferase(ALT),urinary protein quatitation,creatine kinase(CK)before and 2,4,8 weeks after treatment,and the incidence of adverse reactions were compared. RESULTS:Total effective rates of membranous nephropathy and hyperlipidemia were 95.56% and 93.30% in observation group,which were significantly higher than 73.33% and 75.56% in control graup,with statistical significance (P<0.05) .There were no significant differences in TG,HDL-C and LDL-C levels before and 2,4,8 weeks after treatment,and TC level before and 2,4 weeks after treatment between 2 groups (P>0.05);after 8 weeks of treat-ment,TC level in observation group was significantly lower than control group,the differences were statistically significant (P<0.05). Compared with control group,there were no significant differences in AST,ALT,urinary protein quatitation and CK level between 2 groups before and 2,4,8 weeks after treatment(P>0.05). And there was no significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Ezetimibe shows similar clinical efficacy with simvastatin in the treatment of membranous nephropathy complicated with hyperlipidemia,it can effectively reduce TC level,with good safety.

Objective To investigate the expression of syndecan-1 (SDC1) in glioma cells and the effects of synde?can-1 knockdown on the proliferation and invasion of A172 cells. Methods The expression of syndecan-1 in glioma cells was analyzed using quantitative Real-time PCR and Western blotting. A172 cells were transfected with lentiviral vector carrying SDC1 shRNA to establish a stable SDC1-silencing cell line. The cell proliferation was analyzed by MTT assay. Trypan blue exclusion assay and flow cytometry, and Transwell assays were performed to measure the migration and invasion abilities, respectively. The mRNA and protein and expression levels of SDC1, Proliferation Cell Nuclear An?tigen (PCNA) and Matrix Metalloproteinase 9 (MMP-9) were detected by using qRT-PCR and Western blotting. Results The expression levels of SDC1 were significantly different in different glioma cell lines. The stable SDC1-silencing cell line was successfully established, in which the mRNA and protein expression levels of SDC1 were significantly decreased (P<0.05). SDC1 knockdown significantly reduced the cell proliferation, migration(58.40±5.24 vs. 255.8±16.09、226.5± 22.84,F=126.4,P<0.05)and invasion(61.67 ± 16.26 vs. 233.70 ± 17.24、244.30 ± 28.15,F=69.87,P<0.05)compared with either control group or blank group. SDC1 knockdown also significantly decreased the mRNA and protein expression levels of PCNA and MMP-9 (P<0.05). Conclusion:SDC1 knockdown suppresses the capacities of proliferation, invasion and migration of glioma A172 cell, implying that SDC1 may serve as a novel target in the biotherapy of glioma.

Objective To investigate the effect of different gene expression levels of Syntenin on invasion and mi?gration of glioma cells and the underlying molecular mechanisms. Methods Lentiviral RNA interference was used to knockdown the expression of syntenin in U-87 cells. Real-time quantitative PCR was used to detect mRNA expression levels of syntenin . Transwell assay and adhesion assay were used to examine the invasion, migration and adhesion, re?spectively. Western-blot was used to detect the protein expression levels of Syntenin, AKT, p-AKT, and MMP-9. Re?sults The mRNA expression level of Syntenin was greatly reduced in interference group compared with empty vector group (P<0.01). The ability of invasion and migration was much lower in interference group than in empty vector group (P<0.01). However, there were no significant differences in invasion and migration between empty vector group and con?trol group. The adhesion ability of glioma U-87 cells was much higher in interference group than in empty vector group (P<0.05). However, when U-87 cells were seeded on 96-wells coated with HUVEC, the adhesion ability was much lower in interference group than in empty vector group(P<0.05). The protein expression levels of Syntenin, p-AKT, and MMP-9 in interference group were markedly decreased compared with empty vector group(P<0.05). There was no signif?icant difference in expression of AKT protein between interference group and empty vector group (P>0.05). Conclusion Syntenin may enhance the invasion and migration ability of glioma though up-regulation of p-AKT, which in turn pro?motes MMP-9 expression in a corresponding signal transduction pathway.

Ferroptosis is an iron-dependent novel type of programmed cell death. The main features of ferroptosis include lipid reactive oxygen accumulation, iron accumulation and lipid peroxidation. The main mechanisms and signal pathways of ferroptosis are complex and closely related to cystine/glutamate antiporter system, glutathione peroxidase 4, ferroptosis suppressor protein 1, and dihydroorotate dehydrogenase. This review summarizes the current regulatory mechanisms of ferroptosis and discusses the research progress of ferroptosis in tumors, non-alcoholic fatty liver disease, Parkinson's disease, and congestive heart failure.

OBJECTIVETo study the values of immunohistochemistry staining and cytological diagnosis by using cell block sections prepared with the effusion fluid cytology specimens.
METHODSNinety-nine effusion cytology specimens with the diagnoses of reactive mesothelial hyperplasia, atypical cells and metastatic carcinoma were enrolled into the study. The cytospin preparations/smears, cell block sections and immunohistochemical study were performed and correlated with the clinical findings and follow-up data.
RESULTSAmongst the 99 cases studied, the percentage with positive diagnosis using cytospin preparations/smears was 68.7% (68/99). The percentages with negative and equivocal diagnoses were 16.2% (16/99) and 15.1% (15/99), respectively. As for cell block sections, the percentages were 71.7% (71/99), 16.2% (16/99) and 12.1% (12/99), respectively. On the other hands, the percentages became 76.8% (76/99), 20.2% (20/99) and 3.0% (3/99), respectively, when coupled with immunohistochemical findings. The overall percentages of positive, negative and equivocal diagnoses were 77.8% (77/99), 17.2% (17/99) and 5.0% (5/99), respectively, upon clinicopathologic correlation. The difference between cytospin preparations/smears and cell block sections was not statistically significant (P > 0.05). When coupled with immunohistochemical findings or clinicopathologic correlation, the difference in rates of equivocal diagnosis however carried statistical significance (P < 0.05). The false-negative rate of immunohistochemical study applied on cell block sections was 1.0% (1/99).
CONCLUSIONSImmunohistochemistry, when applied on cell block sections, is useful in delineation of the primary origins of the tumor cells in effusion fluid cytology specimens. Combination of morphologic examination, immunohistochemical findings and clinicopathologic correlation can further improve the rate of positive diagnosis.
