RESUMO
Objective:To explore the current situation of college students′ risk behavior and its relationship with alexithymia.Methods:A total of 992 college students from two colleges in Jiangxi Province were investigated with evaluation scale for risk behaviors of teenagers and Toronto alexithymia scale. SPSS 17.0 software was used for descriptive statistics, correlation analysis and regression analysis.Results:Evaluation scale for risk behaviors showed that 15.2% of college students had at least one risk behavior factor scored more than 3, and 1.0% had at least one factor scored more than 4. The scores of bad habits and extroversion behavior question of boys((1.72±0.50), (1.61±0.56)) were significantly higher than those of girls ((1.66±0.38), (1.45±0.40), t=2.205, P=0.028, t=5.020, P<0.01), and the scores of introversion behavior question and academic maladjustment of girls ((2.13±0.56), (2.51±0.53)) were significantly higher than those of boys ((1.97±0.62), (2.39±0.63), t=-4.157, P<0.01, t=-3.282, P=0.001). The four factors of risk behaviors were positively correlated with each other (0.497-0.673), and the risk behaviors of college students were clustered. There were significant differences in the total score of risk behaviors ((2.28±0.43), (1.99±0.37), (1.71±0.36)), introversion behavior question ((2.60±0.54), (2.17±0.49), (1.80±0.50)), bad habits ((1.95±0.49), (1.73±0.38), (1.54±0.36)), academic maladjustment ((2.82±0.52), (2.57±0.50), (2.25±0.54)) and extroversion behavior question ((1.72±0.56), (1.57±0.46), (1.37±0.38)) in alexithymia group, possible alexithymia group and non alexithymia group( F=157.252, 172.027, 75.654, 85.424, 45.604, all P<0.01). Multiple stepwise regression analysis showed that alexithymia could predict college students′ risk behaviors. Conclusion:Taking effective measures to reduce the level of alexithymia can reduce the occurrence of risk behaviors of college students.

RESUMO
In an attampt to establish the functional expression of STGC3 with doxycycline (Dox) induced Tet-onregulating system in human nasopharyngeal carcinoma cell line CNE2, an ideal experimental platform wasprovided for further studies of STGC3. pTet-on regulating plasmid was transfected into CNE2, and stableexpression of Tet-on was established in CNE2 through G418 select. Then the response plasmid of recombinantpTRE-STGC3 was steadily transfected into positive CNE2/Tet-on cells with hygromycin screen. Dox was used toinduce the expression of STGC3 and a cell clone sensitive to Dox was selected. The best-induced concentrationwas determined with different concentration of Dox induction. Growth curves, clone formation rate and cell cycledistribution were detected after STGC3 gene up-regulated expression with Dox induction. The growth capacity andclone formation potential of CNE2/Tet /pTRE-STGC3 was significantly suppressed, compared with the controls(P
RESUMO
BACKGROUND: Neural behavior is a sensitive parameter for predicting abnormal central nervous growth that is resulted from multiple factors. Therefore this study was designed to explore the influence of hypothermia and cigarette smoke exposure during pregnancy on neural behavioral growth of neonatal rats.OBJECTIVE: To study the influence of hypothermia and cigarette smoke exposure on neural behavioral growth of neonatal rats.DESIGN: Randomized case control study based on experimental animals. SETTING: Obstetric and Gynecological Department , Third Affiliated Hospital of Xinxiang Medical College; Cytobiological Department of Xinxiang Medical College.MATERIALS: Totally 270 healthy unpregnant SD rats were obtained, including 180 males with body mass of 190- 210 g, and 90 female rats with body mass of 225-275 g. Rats were raised with granulated feed and drinking water routinely in room of 25 ℃ with natural sunlight. Male and female rats in estrus were put in the same cage overnight in proportion of 2: 1, pregnancy was confirmed if vaginal bolt was observed the following morning. Totally 160 pregnant rats were obtained and randomly divided into 16 groups that were exposed to hyperthermia, cigarette smoke or their combination and by this way, earlier reflex, learning and memory of neonatal rats were observed after natural delivery,INTERVENTIONS: From the second day of pregnancy, rats in 37 ℃, 41 ℃,42 ℃ hyperthermia combining cigarette group received subcutaneous injection of 1 mL smoke hydrotrope every other day, while rats in 25 ℃ control group and 37 ℃, 41 ℃, 42 ℃ single hyperthemia groupwere given 2.0 mL double distilled water every day for totally 7 times. From the pregnancy of 10 days, pregnant rats were put into incubator, and rats anus temperature should be kept respectively at(37 ±0.5) ℃, (41 ±0.5)℃, (42 ±0.5)℃in the 37 ℃, 41 ℃, 42 ℃ of single hyperthemia groups and the temperature should last for 2.0 minutes; nats of 37 ℃, 41 ℃, 42 ℃hyperthemia combining cigarette group received the same treatment and were divided into four subgroups with the duration of 0. 5, 1.0, 1.5, 2.0 minutes respectively;rats in 25℃ control group were not exposed to hyperthermia. Rats were then singly raised from the pregnancy of 18 days for natural delivery. Pregnant days, number of neonatal rat and death rats were recorded, and visible malformation was observed. The average body masses of each cote of neonatal rats were measured every week. Time of eye-opening, ear-opening, hair-growing and teething were observed for assessing their physical growth. Reflex and sensory function of neonatal rats, such as planar tuning, spatial turning, visual orientation and auditory surprise was observed at 3, 7, 12, 16 days after birth respectively; The mean targeting time of each cote was used as reference for assessing their feflex. Y-lybirinth test was used for assessing learning and memory function of neonatal rats(30 days after birth).MAIN OUTCOME MEASURES: ① Main outcomes: Reflex and sensory, such as planar tuning, spatial turning, visual orientation and auditory surrise. ② Secondary outcomes: Influence of hyperthemia and cigarette exposure on learning memory function of neonatal rats.RESULTS: For hyperthermia group(41C and 42C), targeting time of neonatal rat physical growth(eye-opening, ear-opening, hair-growing and teething) and reflex sensory function(planar tuning, spatial turning, nvisual orientation and auditory surprise), as well as learning and memory(minute) were obviously delayed in contrast with those of the control group and 37 C group(χ2 = 11.34, P ＜0.01 ); meanwhile, longer hyperthermia exposure (1.5 minutes) combined with cigarette smoke had supplementary effect on the above neural behaviors, which was significantly different from that of single hyperthermia group(χ2=10.29, P＜0.01).CONCLUSION: Abnormal neural behavior of neonatal rats, such as growing retardation, learning and memory obstacle could be induced by the combination of longer hyperthemia exposure and cigarette smoke.
