Objective To explore the nicotine dependence levels and the influencing factors of dependence among rural-to-urban migrant workers in Shanghai so as to provide scientific rationales for an effective implementation of tobacco control.Methods Multi-stage randomized sampling was used to select a total of 5 856 rural-to-urban migrant workers from 7 districts in Shanghai.Fagerstrom Test for Nicotine Dependence ( FTND) and logistic regression model were used to analyze the association between nicotine dependence and relevant risk factors.Results The current smoking prevalence was 23.7%.The average FTND score for current smokers , high dependence and low dependence were 3.38 ±2.49, 7.00 ±1.07 and 2.23 ±1.71 respectively.The high and low dependence rates were 21.7% and 78.3%.The results of logistic regression showed that education , duration of smoking and length of migration were associated with nicotine dependence.Lower level of education was more prone to high nicotine dependence.Those with a lower education had a higher risk of nicotine dependence ( junior high school: OR=1.742, primary school or lower: OR =1.994 vs.senior high school or higher ).High nicotine dependence increased with the duration of smoking (smoking 6-10 years:OR=3.007, 11-15 years:OR=4.076, 16-20 years:OR=5.451, 20 years or more:OR=5.726 vs.5 years or less).Length of migration over 3 years was less likely to have a high nicotine dependence (3-5 years: OR=0.602, more than 5 years: OR=0.407 vs.<1 year) .Conclusion The rate of high nicotine dependence is high among rural-to-urban migrant workers in Shanghai.Level of education , duration of smoking and length of migration are significant influencing factors of nicotine dependence.

Objective To survey the mental health status of rural-to-urban migrant workers in Shanghai.Methods The survey subjects were selected from migrant workers in Shanghai with a multi-stage stratified cluster sampling method.The Symptom Check List ( SCL-90 ) scores were used for evaluation of metal health status.Results The prevalence of mental health problem of 5 626 rural-to-urban migrant workers in Shanghai was 18.8% ( 1 058/5 626 ).The mean total score of SCL-90 was 114.86 ±31.21.Compulsive-obsessive, interpersonal sensitivity, hostility ranked the top three among 9 factors, with scores of 1.37 ±0.43, 1.31 ±0.43 and 1.30 ±0.41 respectively.The mean total scores and scores of 9 factors of rural-to-urban migrant workers in Shanghai were lower than those of Chinese adults norm the mean total scores(129.96 ±38.76) ( t =-15.34, -3.84 --24.08 respectively, all P <0.01) .There were significant differences in mental health among migrant workers with different age , education , marital status , living conditions and occupation (all P<0.05).Conclusion The prevalence of mental health problems in Shanghai rural-to-urban migrant workers is high, with are related to their age, education, marital status, living conditions and occupation.

Objective To observe serum and callus leptin expression in rats model with fracture and traumatic spinal cord injury (SCI). Methods 72 male SD rats were randomized equally into 4 groups: control, SCI group, fracture group, and fracture/SCI group. Rats were sacrificed at 7, 14, 21 and 28 days after fracture/SCI. Serum leptin was detected by radioimmunoassayat 1, 7, 14, 21 and 28 days, and callus formation was measured radiologically at 14, 21 and 28 days. Callus leptin was analyzed with immunohistochemistry. Results Serum leptin in the fracture group, SCI group and combined fracture/SCI group were all higher than in control group at the 1, 7, 14 and 21 day time-point (P < 0.05). Serum leptin in the combined fracture/SCI group was significantly higher than the fracture group at 7, 14 and 21 days (P < 0.05), and higher than SCI groups at 14 and 21 days after operation (P < 0.05). The percentage of leptin-positive cells in the fracture/SCI callus, and callus volume was significantly higher than the fracture-only group (P < 0.001). Conclusions Leptin expression increases in the recovery process after SCI, and the recovery of fracture becomes sooner.

OBJECTIVETo determine the effect of arousal methods for prolonged coma of 175 patients with severe traumatic brain injury and related factors.

METHODSThere were 175 cases with persistent coma longer than 1 month after severe traumatic brain injury. Coma lasted 1-12 months. Arousal procedures included hyperbaric oxygen, physical therapy and arousal drugs.

RESULTSIn the 175 prolonged coma patients 110 got recovery of consciousness; in 118 cases with coma of 1-3 months, 86 cases recovered consciousness (72.9%); in 42 cases with coma of 4-6 months, 20 cases recovered consciousness (47.6); and in 15 cases with coma of longer than 6 months, only 4 cases recovered consciousness (26.7%). The recovery of consciousness depended on patient's primary brain stem damage, cerebral hernia, GCS score, and age.

CONCLUSIONSApplication of appropriate arousal procedures improves recovery of consciousness in patients with prolonged coma.

OBJECTIVE: MicroRNAs (miRNAs) play a vital role in pathogenesis and progression of many cancers, including cervical cancer. However, importance of serum level of miR-101 in cervical cancer has rarely been studied. In the present study, clinical significance and prognostic value of serum miR-101 for cervical cancer was investigated. METHODS: Association between miR-101 level in cervical cancer tissues and prognosis of patients was analyzed by using data retrieved from The Cancer Genome Atlas (TCGA) database, which was followed with our clinical study in which miR-101 serum level comparison between cervical cancer patients and healthy controls was conducted by real-time quantitative polymerase chain reaction (PCR). RESULTS: TCGA database demonstrated that miR-101 was down-regulated in cervical cancer tissues compared with normal cervical tissues, and univariate Cox regression analysis indicated that decreased miR-101 expression was a highly significant negative risk factor. Similar trend was found in the serum miR-101. Serum level of miR-101 was associated with International Federation of Gynecology and Obstetrics (FIGO) stage (p=0.003), lymph node metastasis (p=0.001), and serum squamous cell carcinoma antigen (SCC-Ag) level >4 (p=0.007). The overall survival time of cervical cancer patients with a higher level of serum miR-101 was significantly longer than that of patients with a lower level of serum miR-101. Moreover, multivariate Cox regression analysis indicated that the down-regulated serum level of miR-101 was an independent predictor for the unfavorable prognosis of cervical cancer. CONCLUSION: Serum level of miR-101 is closely associated with metastasis and prognosis of cervical cancer; and, hence could be a potential biomarker and prognostic predictor for cervical cancer.

OBJECTIVETo investigate the effects of Liuweidihuang pills (LP) on visceral fat deposition in Otsuka Long-Evans Tokushima Fatty (OLETF) rats.

METHODSForty male OLETF rats were randomly divided into LP group and control group (n=20 per group), and 10 male Long-evans Tokushima Otsuka (LETO) rats were used as normal controls. The rats in LP group were given LP(2.4 mg/kg) daily by intragastric administration since the age of 8 weeks, and those in the other two groups were given water of the same volume by intragastric administration. Blood glucose of all the rats was determined by oral glucose tolerance test (OGTT) and visceral fat deposition examined after the rats were sacrificed.

RESULTSOLETF rats had obviously greater amount of visceral fat than LETO rats (P<0.05) and administration of LP ameliorated the increment of visceral fat deposition in this type 2 diabetic model, producing significant effect at the age of 40 weeks (P<0.01).

CONCLUSIONLP may effectively decrease visceral fat deposition in OLETF rats.

OBJECTIVETo investigate the relationship between visceral fat depot and adiponectin level in OLETF rats.

METHODSTwenty male OLETF rats and 10 male Long-Evans Tokushima Otsuka (LETO) rats were subjected to regular oral glucose tolerance test (OGTT). The rats were sacrificed at the ages of 8, 32 and 40 weeks for measurements of the body weight, blood glucose, blood lipid level, blood insulin, and weight of the visceral fat.

RESULTSCompared with LETO rats, OLETF rats had significantly higher body weight and visceral fat with impaired glucose tolerance (P<0.05). OLETF rats also had higher blood insulin, TG, FFA and CHOL levels (P<0.05). The plasma adiponectin level was significantly lower in OLETF rats than in LETO rats at different ages (P<0.05). The adiponectin mRNA level in the adipose tissue of OLETF rats was comparable with that in LETO rats, but significantly decreased at 32 and 40 weeks of age (P<0.01).

CONCLUSIONPlasma adiponectin level is significantly correlated to insulin sensitivity and visceral fat depots in OLETF rats, but a lowered APN mRNA expression level is not the main reason for a decreased plasma adiponectin level in the early stage.

OBJECTIVETo study the effects of Liuweidihuang pills in preventing diabetes in Otsuka Long-Evans Tokushima Fatty (OLETF) rats.

METHODSForty male OLETF rats were randomized equally into Liuweidihuang pill group and control group, with 10 male LETO rats as the normal control group. In Liuweidihuang pill group, the rats were given the pills intragastrically at the daily dose of 2.4 mg/kg since 8 weeks of age, and the rats in the other two groups received water instead. Blood glucose of the rats was determined by oral glucose tolerance test (OGTT), and the body weight and food intake were monitored on a weekly basis. At 8, 32 and 40 weeks, the rats were sacrificed and the expression level of adiponectin mRNA in the adipose tissue was detected using RT-PCR.

RESULTSTreatment with Liuweidihuang pills significantly lowered the increment of the blood glucose and postponed the onset of hyperglycemia in the rats. Compared with the control group, the rats in Liuweidihuang pill group showed significantly increased expression of adiponectin mRNA in the adipose tissue. The rats receiving Liuweidihuang pills developed diabetes at 30 weeks of age with an incidence of 28.6% at 40 weeks, significantly lower than that in the control group (P<0.01).

CONCLUSIONLiuweidihuang pills can significantly increase the expression of adiponectin mRNA in the adipose tissue and decrease the incidence of type 2 diabetes in OLETF rats.
