Objective To study the effect of TBTCl on the immunity of mice. Methods The mice were randomly divided into 5 groups, namely groups of negative control, low dose (0.8 mg/kg), moderate dose (4 mg/kg), high dose (20 mg/kg) and positive control. Gavage was employed to administrate TBTCl to mice for two consecutive weeks, the number of T-lymphocyte in blood and invert ability of T-lymphocytes in spleen, hemolysin in serum, clearance exponent and viscera quotiety were determined to study the effect of TBTCl on immunity of rats. Results Compared with the control, no significantly increased T-lymphocytes were seen in low dose group, in moderate dose group the number of T-lmphocyte and the production of hemolysin increased, no obvious changes in the clearance exponent and viscera quotiety were seen. In high dose group, a significantly decreased T-lymphocytes, the clearance exponent and viscera quotiety were observed. Conclusion Low level TBTCl exposure may stimulate the immune system of mice, high exposed to TBTCl may intensively inhibit the immune system.

Objective:To analyze the autistic severity and developmental level of children with autism spectrum disorder (ASD) of different gender and age.Methods:From March 2018 to February 2019, a total of 286 ASD children aged 18-96 months were enrolled.Severity of ASD was evaluated by the autism behavior checklist (ABC) and the childhood autism rating scale (CARS), while the Griffiths mental development scales-Chinese (GDS-C) was used to evaluate the children's mental development.According to gender and age, ASD severity and developmental levels of different subgroups were analyzed.SPSS 23.0 statistical software was used to analyze the data.According to the non-normal distrbution of variables, Mann-Whitney U test was used for comparison between the two groups, and Kruskal-Wallis H test was used for comparison between multiple groups and Spearman correlation analysis was used to analyze the correlation between two variables. Results:No gender difference was found in the total scores of ABC (52(40, 62), 57(36, 67), Z=0.661, P=0.509) and CARS (31(28, 35), 33(27, 36), Z=0.672, P=0.502) between the ASD boys and ASD girls.No gender difference was found in the total scores of ABC (43(33, 53), 52(34, 58), Z=0.717, P=0.473) and CARS (29(26, 32), 27(26, 30), Z=0.212, P=0.832) between the ASD boys and ASD girls when the general quotient of the GDS-C were all greater than or equal to 70 points.Also, no gender difference was found in the total ABC (55(44, 67), 59(40, 67), Z=0.067, P=0.947) and CARS (32(30, 35), 34(30, 36), Z=0.657, P=0.511) between the ASD boys and ASD girls when the general quotient of the GDS-C were all less than 70 points.The eye-hand coordination (64(52, 77), 60(43, 72), Z=2.138, P=0.033), performance (68(51, 86), 59(43, 68), Z=3.270, P=0.001), and practical reasoning (68(55, 91), 51(33, 58), Z=2.686, P=0.007) quotients of the ASD boys were significantly higher than those of the ASD girls.Compared with boys, a markedly higher proportion of developmental delay (35(80%), 124(51%), χ 2=12.083, P=0.001) was recorded for girls in relation to the performance subscale.There were significant differences in the total scores of ABC and CARS, the locomotor and eye-hand coordination quotients in GDS-C among ASD children of different ages(all P<0.05). The older the first diagnosis age, the lower the scores.The age of initial diagnosis was negatively correlated with the total scores of ABC ( r=-0.259), CARS ( r=-0.268), general quotient of GDS-C ( r=-0.127), locomotor ( r=-0.275), eye-hand coordination ( r=-0.213), performance ( r=-0.160) and practical reasoning ( r=-0.307) (all P<0.05), while positively correlated with hearing and language development quotient ( r=0.143) ( P<0.05). Conclusion:No significant gender difference was found on the severity of ASD in children aged 18 to 96 months, but the developmental level of some areas in boys was better than that of girls with ASD.ASD severity and developmental level vary depending on the age at which their ASD was diagnosed.The age of initial diagnosis is related to the severity and developmental level of ASD.

AIM: To investigate the effect of exercise stress on chronic cigarette smoking-induced downregulation of expression of large-conductance calcium-activated potassium channel (BK_(Ca)) and voltage-dependent delayed rectifier potassium channel (Kv1.5) in rat bronchial smooth muscle cells. METHODS: Rats were divided into 3 groups: normal control, smoking control and smoking plus exercise training group. The alteration of airway responsiveness and plasma cortisol level were detected, and potassium channel expression and pathological changes in lung tissue were determined with HE staining, immunohistochemistry, in situ hybridization and Western blot techniques. RESULTS: (1) Cigarette smoking induced an increase in airway responsiveness, smoking plus exercise lead to a decrease in airway responsiveness in contrast to smoking control group; (2) Plasma level of cortisol determined immediately after exercise was higher than that determined before exercise; (3) HE staining showed that there was severe chronic pulmonary inflammatory response in smoking control group, which was slight in the smoking plus exercise group; (4) The protein and mRNA expression of BK_(Ca) in cigarette smoking group were less than that in control group in BSMC, the mRNA expression of BK_(Ca) in exercise group were higher than that in smoking group; (5) The protein and mRNA expression of Kv1.5 in smoking group were less than that in control group in BSMC, and expression of Kv1.5 in exercise group was higher than that in smoking group in bronchioli. CONCLUSION: Proper exercise training can increase the expression of potassium channel BK_(Ca) and Kv1.5, and increase the cortisol secretion, which may contribute to the decreasing of airway hyperresponsiveness induced by cigarette smoking.

OBJECTIVETo explore the clinical value of screening the serum markers during the second trimester of pregnancy in preventing congenital birth defect and predicting the pregnancy outcome.

METHODSBetween November, 2011 and October, 2013, a total of 25 520 pregnant women (15-20+6 gestational weeks) underwent a screening test of triple serum markers including free beta-human chorionic gonadotrophin (free βhCG), alpha-fetoprotein (AFP), and unconjugated estriol (µE3) during the second semester of pregnancy. The women identified by the screening test as having high risks were referred to invasive prenatal diagnosis by amniocentesis, or to color Doppler ultrasound examination for suspected patent neural tube defect (NTD), and their pregnancy outcomes were followed up.

RESULTSHigh-risk pregnancies were identified by the screening test in 4.91% (1254/25520) of the total cohort. Of the 818 patients receiving invasive prenatal diagnosis, the abnormal rate was 5.75% (47/818). The high-risk pregnancies identified by the screening test was associated with a significantly higher rate of abnormal outcomes compared with the low-risk pregnancies (1.91% vs 0.1%, P<0.01). Of the 210 high-risk cases of NTD, a definite diagnosis was established in 34 cases. We also found that pregnancies at an advanced age (>35 years) was associated with increased risks for trisomy 21 compared with those at younger ages (15% vs 1.65%P<0.01). The detection rate of abnormal karyotypes in pregnancies with an abnormal MoM value of a single marker was 3.17% (6/189).

CONCLUSIONScreening tests of serum markers during the second trimester of pregnancy can be helpful to identify fetal chromosomal and anatomical anomalies, predict unfavorable pregnancy outcomes, and prevent birth defects in pregnancies at an advanced age. The MoM value of a single marker in the second trimester can be indicative of potential chromosomal abnormalities.
