AIM: To know the personality and mental health of the poverty college students. METHODS: 2 400 students of grade 2002, 2003 and 2004 were randomly selected from Fuzhou University, Fujian Normal University, Fujian Agriculture and Forestry University, Fujian Traditional Chinese Medical University and Minjiang College from September to November 2005, including 1 478 schoolboys and 922 schoolgirls with an average age of (20?1) years. According to the prescript of the Message from Fuzhou City Government of Improving the Lowest Life Guarantee Standard of Residents in the City, Town and Country issued by the office of Fuzhou Government in November 4th 2004, 210 Yuan was provided for each one in many-persons family every month and 230 Yuan for single-person family in the town; 155 Yuan was provided for each one in many-persons family every month and 175 Yuan for single-person family in the country. Poverty college student was defined in the paper as the following: Students with lower average family member month income and some debts, who could only afford part of tuition their basic cost of living closed to the lowest life guarantee line in the local residents (230 Yuan was taken as the baseline) were considered as the poverty students. SCL-90 and 16PF were adopted to study the mental health and personality of poverty college students. RESULTS: 2 400 questionnaires were sent out, and 2 111 valid ones were taken back. ① The scores of somatization, compulsion, interpersonal sensitivity, depression, anxiety, hostility, phobia, paranoid, schizophrenia and others as well as the total score of symptom indexes in SCL-90 of poverty college students were significantly higher than those of non-poverty college students Poverty college students: 1.61?0.56,2.02?0.64,1.92?0.63,1.71?0.56,1.65?0.58,1.73?0.68,1.57?0.62,1.81?0.65,1.67?0.54,1.76?0.63,1.74?0.49;Non-poverty college students:1.48?0.45,1.89?0.56,1.79?0.57,1.61?0.51,1.54?0.50,1.61?0.56,1.44?0.49,1.66?0.54,1.54?0.46,1.61?0.53,1.62?0.41,P 0.05). ② The examined rate of psychological problem in poverty college students of Fujian Province was 24.5%, and that of slight psychological problems was 22.6%, and that of moderate psychological problems was 1.7%, and that of severe psychological problems was 0.2%. Among sub-specific factors, the psychological problems were prominent in obsessive-compulsive, interpersonal sensitivity, paranoid, depression, hostility, anxiety, etc. ③ Compare to non-poverty university students, the scores of poverty university students on sociality, intelligence, excitability, sensitivity, suspicion were distinctly lower, while the marks on permanence, anxiety, independence were significantly higher (Poverty college students: 5.20?1.77,4.70?1.93,5.49?1.87,6.46?1.79,4.29?1.71,4.60?1.63,6.64?1.82,5.07?1.82;Non-poverty college students:5.39?1.74,4.95?1.99,5.82?1.91,6.66?1.75,4.55?1.77,4.36?1.69,6.43?1.94,4.89?1.77,P

OBJECTIVE: To observe the therapeutic effects of Yiqi Sanju Formula (YQSJF), a compound traditional Chinese herbal medicine, in treatment of non-alcoholic fatty liver disease (NAFLD). METHODS: Sixty-seven patients diagnosed with NAFLD were randomly divided into two groups: YQSJF-treated group (39 cases) and placebo group (28 cases). The NAFLD patients in the two groups were treated with YQSJF and placebo respectively for 3 months. Clinical symptoms, the CT ratio of liver-spleen, body mass index (BMI), waist circumference, homeostatic model assessment for insulin resistance (HOMA2-IR) and the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), tumor necrosis factor-alpha (TNF-alpha), high sensitivity C-reactive protein (hs-CRP), triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) were evaluated before and after treatment. RESULTS: After treatment, the clinical symptoms were improved and the levels of BMI, waist circumference, HOMA2-IR, ALT, AST, TG and TC were decreased significantly in the YQSJF-treated group (P<0.05). The CT ratio of liver-spleen in the YQSJF-treated group was increased significantly as compared with the placebo group (P<0.01).

OBJECTIVE: To observe the effects of Pollen Typhae total flavones (PTF) on expression of interleukin-6 (IL-6) mRNA and protein secretion in C2C12 cell strain of skeletal muscle cells cultured with palmitate, and to explore the mechanism of PTF in relieving insulin resistance (IR). METHODS: The IR of C2C12 cells was induced by co-culturing with palmitate. The C2C12 cells were divided into normal control group, untreated group, PDTC (a nuclear factor-kappaB inhibitor) treated group, rosiglitazone (ROS)-treated group, ROS+ PDTC-treated group, PTF-treated group and PTF+PDTC-treated group. Sixteen hours after culture, the transportation rate of glucose was observed by (3)H-deoxyglucose uptake method; IL-6 mRNA expression in C2C12 cells was assayed by real time polymerase chain reaction (Real-time PCR), and level of IL-6 protein secretion in culture supernatant was detected by enzyme linked immunosorbent assay. RESULTS: Compared with the normal control group, the transportation rate of glucose of cells in untreated group was decreased 30.43% after 16-hour palmitate culture, and was increased 32.39% in the PTF-treated group. Compared with the untreated group, the levels of IL-6 mRNA expression in cells and IL-6 protein secretion in supernatant were significantly decreased in the PTF-treated group (P<0.05). The levels of IL-6 mRNA expression in cells and IL-6 protein secretion in supernatant were increased in PTF+PDTC-treated group as compared with PFT-treated group (P<0.05). CONCLUSION: PTF can inhibit the IL-6 mRNA expression and IL-6 protein secretion via nuclear factor-kappaB pathway in C2C12 skeletal muscle cells, which may be one of its mechanisms in relieving inflammation conditions and insulin resistance in C2C12 skeletal muscle cells.

Objective To establish a PCR-based capillary electrophoresis(PCR/CE)to detect Survival Motor Neuron 1(SMN1)and Survival Motor Neuron 2(SMN2)genes and to evaluate its performance.Methods PCR/CE and Multiplex Ligation-dependent Probe Amplification(MLPA)for SMA gene diagnosis were used to blindly test the samples in sync.The performance of PCR/CE was assessed using MLPA results as the standard.Results A total of 336 samples were included in this study,consisting of 50 homozygous deletion types(14.9%),65 heterozygous deletion types(19.3%),and 221 non-deletion types(65.8%).The results of PCR/CE for detect-ing SMN1 and SMN2 copy numbers(0,1,2,3,≥4)were in complete agreement with the results of the MLPA.Conclusions PCR/CE for gene testing related to SMA could accurately detect copy numbers of exon 7 and exon 8 of the SMN1 and SMN2 genes(0,1,2,3,≥4).

OBJECTIVE: To investigate the change of pulmonary ventilation function in patients with simple type and complex type pneumoconiosis based on high resolution computed tomography(HRCT). METHODS: A total of 188 male patients with pneumoconiosis were selected as the study subjects by judgment sampling method. Patients were divided them into simple type group(104 cases) and complex type group(84 cases) according to their chest HRCT findings. Another 80 healthy men who have no dust and other occupational hazard exposure were selected as the control group. The lung function tests were performed in patients in these three groups. RESULTS: The indexes of pulmonary function including vital capacity, forced vital capacity(FVC), forced expiratory volume in one second(FEV_1), FEV_1/FVC%, peak expiratory flow, forced expiratory flow at 25% of FVC exhaled, forced expiratory flow at 50% of FVC exhaled, forced expiratory flow at 75% of FVC exhaled and forced expiratory flow at 25% to 75% of vital capacity were lower in patients with pneumoconiosis of simple type and complex type groups than that in the control group(all P<0.01). The above indexes in the complex type group were lower than that in the simple type group(all P<0.01). The detection rate of pulmonary ventilation dysfunction in patients with pneumoconiosis was 64.9%. Among them, the detection rate of obstructive, restrictive and mixed ventilation dysfunction were 33.5%, 5.3% and 26.1%, respectively. The detection rates of pulmonary ventilation dysfunction and mixed ventilation dysfunction were higher in complex type group than that in simple type group(82.1% vs 51.0%, 41.7% vs 13.5%, all P<0.01). The severe and extremely severe pulmonary ventilation dysfunction was higher in complex type group than that in simple group(20.2% vs 8.6%, 21.4% vs 3.8%, all P<0.05). CONCLUSION: The types of pulmonary ventilation dysfunction in patients with pneumoconiosis are mainly obstructive and mixed. The pulmonary ventilation dysfunction tends to develop from obstructive to mixed with the increasing severity of pneumoconiosis. The pulmonary ventilation dysfunction in patients with complex type pneumoconiosis is more serious than that in patients with simple type pneumoconiosis. The HRCT image classification is related to the status of patients' pulmonary ventilation dysfunction.
