ABSTRACT
Objective To investigate the risks of pre-pregnancy overweight,excessive gestational weight gain on macrosomia.Methods We conducted one hospital-based cohort study,focusing on pregnant women from January 2015.All pregnant women attending to this hospital for maternal check-ups,were included in our cohort and followed to the time of delivery.Data related to general demographic characteristics,pregnancy and health status of those pregnant women,was collected and maternal pre-pregnant BMI and maternal weight gain were calculated.Logistic regression was used to explore the risk difference of pre-pregnancy BMI,excessive gestational weight gain on macrosomia.Results The overall incidence of macrosomia in our cohort appeared as 6.6％ (149/2 243).After adjusting the confounding factors including age and histories on pregnancy,prepregnancy overweight/obesity was associated with higher risks of macrosomia (OR=3.12,95％ CI:1.35-7.22,P=0.008;OR=2.99,95％CI:1.17-7.63,P=0.022) when comparing to those with normal pre-pregnancy weight.Cesarean delivery and sex of the offspring were associated with higher risk of macrosomia,while excessive gestational weight gain showed no significant difference (OR=1.41,95％CI:0.96-2.09,P=0.084).Our data showed that Macrosomia was statistically associated with gestational weight gain (P=0.002).After controlling parameters as age,history of pregnancy and related complications of the pregnant women,results from the logistic regression showed that women with gestational inadequate weight gain having reduced risks to deliver macrosomia,when compared to those pregnant women with adequate weight gain (OR=0.52,95％ CI:0.30-0.90,P=0.019).Conclusion Pre-pregnancy overweight and obesity were on higher risks to macrosomia.
ABSTRACT
Objective To analyze the function connection of the brain in smokers with resting-state fMRI.Methods Resting-state fMRI data of 53 smokers (smoking group) and 53 non-smokers (control group) were observed.The subjects in smoking group were divided into small or large amount smoking subgroup,as well as mild or severe addiction subgroup.The fractional amplitude of low-frequency fluctuation (fALFF) values of all subjects were calculated,and the differences of fALFF values and whole brain functional connectivity were observed.Results Compared with control group,fALFF significantly increased in the left limbic lobe,and decreased in the right superior temporal gyrus in smoking group.Compared to small amount smoking subgroup,fALFF significantly increased in the right superior temporal gyrus,and decreased in the bilateral limbic lobe in large amount smoking subgroup.Compared with mild addiction subgroup,fALFF significantly increased in the bilateral middle frontal gyrus,and decreased in the left limbic lobe in severe addiction subgroup.There are many increased and decreased functional connectivity brain areas in smoking group compared with control group.Conclusion There are many activity changes in addiction related brain areas and less in emotion control areas in smokers,and some brain areas activation changes are related to smoking amount and addiction level.

ABSTRACT
<p><b>BACKGROUND</b>Nicotine is primarily rsponsible for the highly addictive properties of cigarettes. Similar to other substances, nicotine dependence is related to many important brain regions, particular in mesolimbic reward circuit. This study was to further reveal the alteration of brain function activity during resting state in chronic smokers by fractional amplitude of low frequency fluctuation (fALFF) based on functional magnetic resonance imaging (fMRI), in order to provide the evidence of neurobiological mechanism of smoking.</p><p><b>METHODS</b>This case control study involved twenty healthy smokers and nineteen healthy nonsmokers recruited by advertisement. Sociodemographic, smoking related characteristics and fMRI images were collected and the data analyzed.</p><p><b>RESULTS</b>Compared with nonsmokers, smokers showed fALFF increased significantly in the left middle occipital gyrus, left limbic lobe and left cerebellum posterior lobe but decreases in the right middle frontal gyrus, right superior temporal gyrus, right extra nuclear, left postcentral gyrus and left cerebellum anterior lobe (cluster size >100 voxels). Compared with light smokers (pack years ≤ 20), heavy smokers (pack years >20) showed fALFF increased significantly in the right superior temporal gyrus, right precentral gyrus, and right occipital lobe/cuneus but decreased in the right/left limbic lobe/cingulate gyrus, right/left frontal lobe/sub gyral, right/left cerebellum posterior lobe (cluster size >50 voxels). Compared with nonsevere nicotine dependent smokers (Fagerstrőm test for nicotine dependence, score ≤ 6), severe nicotine dependent smokers (score >6) showed fALFF increased significantly in the right/left middle frontal gyrus, right superior frontal gyrus and left inferior parietal lobule but decreased in the left limbic lobe/cingulate gyrus (cluster size >25 voxels).</p><p><b>CONCLUSIONS</b>In smokers during rest, the activity of addiction related regions were increased and the activity of smoking feeling, memory, related regions were also changed. The resting state activity changes in many regions were associated with the cumulative amount of nicotine intake and the severity of nicotine dependence.</p>

Objective To investigate the incidence and the proper treatment of severe hepatitis during pregnancy. Methods The clinical menifestation and biochemical examination of 29 cases of severe hepatitis during pregnancy were retrospectively analyzed. Results Among 29 cases of severe hepatitis, 7 cases of acute severe hepatitis, 11 subacute severe hepatitis and 11 chronic severe hepatitis were identified. Totally, 2 cases were fully recovered, 13 improved, 5 demised and 5 left without treatment. Fetal death occurred in 1 cases, 2 were stillbirth, and 1 case was neonatal death. The perinatal mortality rate was 43. 8%. Conclusions Severe hepatitis is one of the life-threatening complications during pregnancy. Regular prenatal care and early identification and treatment are crucial to improve the maternal and fetal outcome.
