ABSTRACT
Background Previous studies have shown that active smoking during pregnancy can reduce the level of neonatal cord blood leptin, and thereby affect birth weight. However, few studies have studied the association of passive smoking during pregnancy with leptin in neonatal cord blood and birth weight. Objective To explore the effects of passive smoking in varied pregnancy stages and entire pregnancy on neonatal cord blood leptin level and birth weight in a certain rural area of Yunnan, and potential mediating role of cord blood leptin. Methods Based on a prospective prenatal cohort study conducted in Xuanwei County, Yunnan Province, a total of 545 mother-infant pairs were included in this study from early pregnancy enrollment to delivery. The demographic information and reproductive history of the subjects were collected by questionnaire. The urine samples of pregnant women in the first, second, and third trimesters of pregnancy were collected during regular prenatal examinations. Umbilical cord blood samples were collected from newborns at birth. The concentration of urine cotinine (UC) was measured by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). According to the results of UC level during pregnancy, the study subjects were divided into three groups: negative group (<LOD), low exposure group (LOD-M), and high exposure group(>M). The level of leptin in cord blood was detected by ELISA. Multiple linear regression was used to analyze the effect of passive smoking on umbilical cord blood leptin in newborns during pregnancy. Path analysis was used to explore the relationship among passive smoking during pregnancy, neonatal cord blood leptin, and birth weight. Results The average exposure rate of passive smoking during pregnancy was 87.28%, and the exposure rate for entire pregnancy was 76.88%. The median concentration of leptin in neonatal cord blood was 4.17 μg·L−1. After adjusting for maternal age, ethnicity, educational level, pre-pregnancy body mass index (BMI), gestational weight gain, parity, annual household income, infant sex, and birth weight, we found that low level (b=−3.388, P=0.001) and high level (b=−2.738, P=0.006) of passive smoking in the first trimester of pregnancy had negative associations with leptin concentration of cord blood by multiple linear model. The path analysis results showed that passive smoking in the first trimester and pre-pregnancy BMI directly affected leptin levels, and the sizes of direct effects were −0.073 and −0.087 (both P<0.05) respectively. Passive smoking in late pregnancy, gestational weight gain, premature, newborn girls, parity, and pre-pregnancy BMI directly affected birth weight, and the sizes of direct effects were −0.063, 0.191, −0.301, −0.128, −0.121, and 0.167 (all P<0.05), respectively. No mediating role of leptin was found in the effect of passive smoking on neonatal birth weight. Conclusion Passive smoking exposure during pregnancy is common among rural women in Yunnan Province. Passive smoking in the first trimester may be key in decreasing the leptin level of neonatal cord blood. Passive smoking in third trimester may lead to a decrease in birth weight. No evidence shows that leptin mediates the relationship between passive smoking and birth weight.
ABSTRACT
A 24-year-old male was admitted due to recurrent redness, swelling, fever and pain in the ankle, frequently accompanied by hungry feeling. Dual energy CT scans showed multiple small gouty stones in the posterior edge of the bilateral calcaneus and in the space between the bilateral metatarsophalangeal joints. The laboratory examination results indicated hyperlipidemia, high lactate lipids, and low fasting blood glucose. Histopathology of liver biopsy showed significant glycogen accumulation. The results of gene sequencing revealed the compound heterozygous mutations of the G6PC gene c.248G>A (p.Arg83His) and c.238T>A (p.Phe80Ile) in the proband. The c.248G>A mutation was from mother and the c.238T>A mutation was from father. The diagnosis of glycogen storage disease type Ⅰa was confirmed. After giving a high starch diet and limiting monosaccharide intake, as well as receiving uric acid and blood lipids lowering therapy, the condition of the patient was gradually stabilized. After a one-year follow-up, there were no acute episodes of gout and a significant improvement in hungry feeling in the patient.

Objective:To explore the effect of adult growth hormone deficiency on cognitive function in adults.Methods:A total of 19 hypophyseal or craniopharyngioma patients who underwent surgical treatment and were diagnosed with adult growth hormone deficiency in Department of Endocrinolog, the Second Affiliated Hospital, School of Medicine, Zhejiang University from June 2017 to June 2018 were selected as the case group, and 19 normal people were included as the control group. All the members were assessed with the cognitive function scale and brain functional magnetic resonance examination, data between the groups were analyzed.Results:The body weight within a year of case group was significantly increased than that of the control group( P=0.017). Compared with the control group, the case group was relatively inattentive and had decreased memory(Time of stroop color words test-a, test-c, and trail-making test-A, P values were 0.009, 0.018, 0.020 respectively; Auditory word learning test N6, P=0.008). The executive function and language ability of the case group were weakened compared with the control group(Raven′s matrices score E1-E12, P=0.022; Time cost and the number of arrivals in 1 min of connection test B, P values were 0.023, 0.004; Symbol digit modalities test, P=0.037; The number of words spoken in 46-60 s and total number in 0-60 s of the case group was less than the control, P values were 0.030, 0.006). The general mental state of the case group was worse than the control group( P=0.018). The accuracy of the 2-back task of the case group was significantly lower and the activation signal of the left frontal lobe in the case group was significantly weaker( P<0.005). Conclusions:Adult growth hormone deficiency may increase obesity risk and have a detrimental influence on patients′ overall mental health, resulting in varying degrees of cognitive impairment. Working memory impairments associated with adult growth hormone deficiency may be a result of decreased frontal lobe brain activity.
ABSTRACT
OBJECTIVES@#To verify the applicability and extensibility of the satisfaction index of basic medical insurance for rural and urban residents, and to explore the mechanism responsible for the satisfaction index in Kunming and Changsha City, and provide references for effective management and policy making.@*METHODS@#A stratified cluster sampling method was conducted. A total of 560 familial decision makers were randomly selected in 24 classes of 14 schools of Kunming and Changsha City. Model reliability was tested by SPSS18.0. In addition, Smart PLS 3.0 was applied to conduct model validity test, calculate the satisfaction index, and to compare the model path coefficients of Kunming and Changsha by multi-group analysis.@*RESULTS@#In the application of the satisfaction index of basic medical insurance for rural and urban residents in Kunming, Cronbach's α of the model was 0.93, split-half reliability coefficient was 0.90, and the latent variable composite reliability coefficient values were more than 0.86; the latent variable average variance extraction (AVE) values were greater than 0.66, and the square root of the AVE of each latent variable (all greater than 0.66) was larger than the correlation coefficient with other latent variables. The factor loading values were greater than 0.70, with statistical significance. The basic health insurance satisfaction index of Kunming and Changsha was 60.40 and 52.05, respectively. The difference between the path coefficient of Kunming and Changsha was not statistically significant except the path from public satisfaction to public loyalty. Perceived value had the largest direct and total effect on public satisfaction latent variable in Kunming City. While the perceived value had the largest direct effect on public satisfaction, and the perceived quality had the largest total effect on public satisfaction in Changsha City.@*CONCLUSIONS@#The satisfaction index model reflects the satisfaction of pupils' basic medical insurance for urban and rural residents, and it also shows good reliability and validity in Changsha and Kunming. What's more the model can be extended to the national level to evaluate the satisfaction of basic medical insurance for urban and rural residents for primary school students. The basic health insurance satisfaction index of familial decision makers in Kunming is higher than that of Changsha. There are differences between Kunming and Changsha in the influential mechanism of the satisfaction index of for Chinese pupils with basic medical insurance for rural and urban residents, and the measures taken by the government and relevant departments to improve the satisfaction of basic medical insurance should be based on local conditions.

<p><b>OBJECTIVE</b>To explore genetic mutation and clinical treatment for a patient with globozoospermia.</p><p><b>METHODS</b>Histomorphology of the sperms was studied by Wright-Giemsa staining and transmission electron microscopy. Potential mutation of the DPY19L2 gene was detected by PCR amplification and Sanger sequencing.</p><p><b>RESULTS</b>Wright-Giemsa staining showed that all spermatozoa from the patient were round-headed and lacked the acrosome, with the nuclei of sperm head stained in dark and full. Transmission electron microscopy revealed large round sperm heads, with an even layer of unit membrane surrounding the nuclei and dispersed cytoplasmic vacuoles but no acrosomal structure. The patient has harbored a homozygous deletion of the DPY19L2 gene. With intracytoplasmic sperm injection (ICSI) treatment, fertilization rate of the oocytes has reached 28.6%, which resulted in a successful pregnancy. A healthy male was born.</p><p><b>CONCLUSION</b>The homozygous deletion of DPY19L2 probably underlies the globozoospermia in this case, for which ICSI has provided an effective treatment. However, there is still a risk of low oocyte fertilization rate or fertilization failure. Further studies are required.</p>
