ABSTRACT
Background Zinc is a trace element essential for normal fetal heart development, and excess zinc can be toxic. The relationship between maternal and fetal zinc levels and the development of congenital heart disease (CHD) in the offspring is unclear. Objective To study the effects of maternal and neonatal zinc exposure levels on the risk of developing CHD in the offspring. Methods The data and biological samples of the study subjects were derived from the birth cohort established by Gansu Provincial Maternity and Child Care Hospital in Lanzhou from 2010 to 2012. Questionnaire surveys were conducted at baseline in the first trimester and at follow-up visits in the second trimester, the third trimester, and 42 d after delivery. Maternal venous blood during the third trimester and neonatal umbilical venous blood at delivery were collected, and information on their birth outcomes was extracted from medical records. Ninety-seven children with CHD diagnosed by echocardiography at birth and confirmed at the follow-up after 42 d were selected as the case group, and 194 healthy full-term infants were selected as the control group, 1∶2 matched for maternal age and geographical location from the database. The zinc concentrations in whole blood of pregnant mothers and umbilical cord blood of fetuses in both groups were measured by inductively coupled plasma mass spectrometry. According to the quartiles P25 and P75 of zinc levels in the whole blood of pregnant mothers and neonatal cord blood in the control group, zinc exposure was divided into three groups: low, medium, and high. After adjusting for maternal vaginal bleeding in early pregnancy, pre-pregnancy folic acid and vitamin supplementation, birth weight, and umbilical cerclage confounders, a multiple conditional logistic regression model was applied to analyze the associations between maternal whole blood and fetal umbilical cord blood zinc levels and the risk of CHD in the offspring, and a further subgroup analysis was performed by disease classification. Results The medians (P25, P75) of maternal whole blood zinc levels in the case group and the control group were 5.034 (3.456, 6.644) and 4.693 (3.411, 5.646) mg·L−1, respectively, with significant differences between the two groups (P=0.029). The medians (P25, P75) of neonatal cord blood zinc level was 2.153 (1.479, 2.405) mg·L−1 in the case group and 1.636 (1.304, 1.979) mg·L−1 in the control group, with significant differences between the two groups (P<0.001). The zinc levels of maternal whole blood and neonatal cord blood in the simple CHD group were significantly higher than those in the control group (P<0.05). The multiple conditional logistic regression model showed that compared with the maternal medium zinc exposure level group (3.41-5.65 mg·L−1), the risk of offspring CHD was 2.225 times of the high exposure level group (>5.65 mg·L−1) (OR=2.225, 95%CI: 1.017-4.868). Compared with the neonatal medium zinc exposure level group (1.30-1.98 mg·L−1), the neonatal high exposure level group (>1.98 mg·L−1) also had an increased risk of CHD (OR=4.132, 95%CI: 1.801-9.480). The subgroup analysis results showed that compared with corresponding medium exposure level groups, the risk of simple CHD in the offspring of the maternal high zinc exposure level group was increased (OR=4.081, 95%CI: 1.427-11.669), and the risks of simple CHD (OR=7.122, 95%CI: 2.126-23.854) and complex CHD (OR=5.165, 95%CI: 1.859-14.346) of neonates of the neonatal high zinc exposure level group were increased. Conclusion Under the exposure levels of the study population, high concentrations of zinc exposure in pregnant mothers and neonates may be associated with the incidence of CHD.
ABSTRACT
Objective@#To investigate the health-seeking intention for urinary incontinence among adult women in Gansu Province, so as to provide insights into the management of female urinary incontinence.@*Methods @#Women at ages of 20 years and older who lived in 8 communities and 8 villages of Gansu Province for at least one year were recruited using the multi-stage stratified cluster random sampling method. A face-to-face questionnaire survey was conducted from October 2019 to February 2020, and the demographic features, urinary incontinence status and health-seeking intention were collected and descriptively analyzed.@*Results@#A total of 3 580 questionnaires were allocated and 3 485 were recovered, with a recovery rate of 97.35%. The respondents had a mean age of ( 51.18±17.13 ) years, with 1 759 respondents ( 50.47% ) that lived in urban areas, and 1 726 ( 49.53% ) that lived in rural areas. There were 1 150 respondents with self-reported urinary incontinence ( 33.00% prevalence ), including 340 cases with stress urinary incontinence ( 29.57% ), 78 cases with urge urinary incontinence ( 6.78% ) and 732 cases with mixed urinary incontinence ( 63.65% ). The overall proportion of health-seeking intention for urinary incontinence was 41.57%, and the proportions of health-seeking intention were 51.76%, 39.74% and 37.02% for stress, urge and mixed urinary incontinence, respectively. The proportion of health-seeking intention for urinary incontinence appeared a tendency towards a decline with the increase in household monthly income per capita and frequency of urinary leakage, and appeared a tendency towards a rise with the increase in educational levels ( P<0.05 ). In addition, a higher proportion of health-seeking intention for urinary incontinence was seen in women living in urban areas than in rural areas (5 3.63% vs. 31.98%, P<0.05 ), and a higher proportion was found in women with mental labors than in those with physical labors ( 60.81% vs. 40.24%, P<0.05 ), while a higher proportion was found in married women than in divorced or widowed women ( 44.33% vs. 23.53%, P<0.05 ).@*Conclusions@#There is a low proportion of health-seeking intention for urinary incontinence among adult women in Gansu Province. Age, occupation, place of residence, educational level, income, marital status, and frequency of urine leakage may affect the intention to seek medical care for urinary incontinence among adult women.
ABSTRACT
Objective:To understand the epidemic characteristics of epidemic Japanese encephalitis and the antibody level of healthy people in Longnan City, Gansu Province, analyze and evaluate its epidemic risk, and provide scientific basis for future prevention and control of Japanese encephalitis.Methods:By retrospective analysis, the data of Japanese encephalitis cases in Longnan City from 2015 to 2020 were collected from the "Japanese Encephalitis Monitoring Information Report Management System" of the "China Disease Prevention and Control Information System", and the distributions of the cases(time, region and population distribution) were statistically described and analyzed. In 2018, the cluster stratified sampling method was adopted to select Li County and Xihe County with higher incidence rate of Japanese encephalitis in Longnan City, and Wudu District and Hui County with lower incidence rate as monitoring sites, and 3 administrative villages (communities) were selected from each monitoring site to collect blood samples from healthy people to detect the level of Japanese encephalitis IgG antibodies.Results:From 2015 to 2020, a total of 261 cases of Japanese encephalitis were reported in Longnan City, with an average annual incidence of 1.66 per 100 000; among them, the number of reported cases in 2017 and 2018 accounted for 82.38% (215/261) of the total number of cases. The incidence of Japanese encephalitis was mainly concentrated in August, accounting for 72.03% (188/261); 9 counties (districts) in Longnan City had reported cases of Japanese encephalitis, and the top 5 counties (districts) with the number of cases were Li County (68 cases), Xihe County (64 cases), Wudu District (40 cases), Kang County (33 cases) and Cheng County (18 cases), accounting for 85.44% (223/261) of the total number of cases. The age of onset of Japanese encephalitis cases was mainly concentrated in the 40 - < 60 years old, accounting for 40.23% (105/261); male to female ratio was 1.00 ∶ 1.14 (122 ∶ 139); the occupation was mainly farmers, accounting for 75.86% (198/261). A total of 887 sera samples from healthy people were tested, and the antibody positive rate was 91.09% (808/887); the difference in antibody positive rate of different age groups was statistically significant (χ 2 = 5.77, P < 0.05); the differences of positive rate of antibodies between different genders and regions were not statistically significant (χ 2 = 0.45, 2.06, P > 0.05). Conclusions:The incidence of Japanese encephalitis in Longnan City is mainly middle-aged farmers, with a high incidence in August each year. After the outbreak of Japanese encephalitis in Longnan City in 2017 and 2018, it has showed a low epidemic trend, and the positive rate of Japanese encephalitis antibody in healthy people is high. It is recommended to carry out regular monitoring of Japanese encephalitis immunization level of healthy people and strengthen the immunization of key populations in time.

ABSTRACT
The aim of this study was to evaluate the safety and immunogenicity of the first domestic ACYW135 meningococcal conjugate vaccine and a control vaccine named AC group meningococcal conjugate vaccine for 3 months (90-119 days) infants. From February 2017 to June 2018, a randomized, blinded, and similar vaccine-controlled clinical trial design was adopted at the Henan Vaccine Clinical Research Base. The subjects were 3 months old healthy infants, a total of 720, based on a 1∶1 ratio. The random allocation table for entry was randomly assigned to the experimental group and the control group. According to the 3, 4, and 5 month-old vaccination procedures, the subjects were vaccinated with test vaccine (ACYW135 group meningococcal conjugate vaccine) and control vaccine (group A group C meningococcal polysaccharide conjugate vaccine), of which 720 were given the first dose, 696 were given the second dose (test group: 346; control group: 350), and 692 were given the third dose (test group: 344; Control group: 348). The overall adverse reaction rate of the test vaccine was 21.90% (230 cases), which was lower than the 32.04% (339 cases) of the control vaccine (0.05). Group Y and W135 was 88.17% (298 cases), 99.41% (336 cases), respectively. The GMT results showed that the test vaccine group A was 56.24, the control vaccine was 57.43 (>0.05); the group C test vaccine (43.53) was higher than the control group (27.28) (<0.001). The group Y and W135 are 89.22 and 140.66, respectively. Among them, the proportion of the group C GMT antibody ≥ 1∶128 for test vaccine (31.07%, 105 cases) was higher than the control vaccine (16.22%, 55 cases) (<0.001). ACYW135 group meningococcal conjugate vaccine has more safety and immunogenicity after application to 3 month old infants.

ABSTRACT
Objective To investigate the relationship between maternal body composition in first trimester and gestational diabetes mellitus (GDM). Methods In this nested case-control study based on a prospective cohort study, we enrolled gravidas between 8 and 14 weeks of gestation, who received prenatal care and voluntary nutrition evaluation in Gansu Provincial Maternity and Children Health Care Hospital, from July 2016 to January 2017. Body mass index (BMI) of each gravida was recorded and the maternal body composition including body fat, body fat percentage and fat-free mass was measured by bioelectrical impedance analysis. Pregnancy outcomes were followed up. A total of 70 patients diagnosed with GDM were allocated to the GDM group and 140 healthy gravidas matching for age and pre-pregnancy BMI were selected as the control group. Differences in body composition between two groups and their relationships with GDM were analyzed by Chi-square test and multivariate logistic regression. ResuLts Maternal BMI ≥ 30 kg/m2 (OR=1.973, 95%CI:1.095-7.664, P=0.024) and body fat percentage≥30%,≥35% and≥40% in first trimester (OR=1.261, 95%CI:1.021-2.982, P=0.010; OR=4.020, 95%CI: 1.341-7.950, P<0.001; OR=8.311, 95%CI: 5.018-42.771, P<0.001) were the risk factors of GDM. ConcLusions BMI ≥ 30 kg/m2 and body fat percentage ≥ 30% in first trimester are risk factors for GDM and excessive adipose tissue may play an important role in the development of GDM.

ABSTRACT
Objective@#To investigate the influence of occupational stress on recurrent spontaneous abortion (RSA) in women of childbearing age.@*Methods@#From January to December, 2017, 75 working women of childbearing age (25-35 years) who were admitted to a provisional hospital in Lanzhou, China and diagnosed with RSA were assigned into patient group. At a 1∶4 ratio, 300 age-matched working women who had normal first pregnancy were randomly selected as controls. A case-control study was conducted by a self-made questionnaire and the effort-reward imbalance scale. The impact of occupational stress on RSA in women of childbearing age was analyzed by evaluation of occupational harmful factors, regularity, effort-reward ratio, and sleep quality.@*Results@#There were significant differences in the distribution of sleep, daily exercise, night shift, extrinsic-effort/low-reward score, and effort/low-reward score between the patient group and the control group (χ2=7.867, P<0.05; χ2=7.377, P<0.05; χ2=3.714, P<0.05; χ2=6.651, P<0.05; χ2=8.556, P<0.05) . With controlled factors such as general conditions and living habits, logistic regression analysis showed that poor sleep quality and high-effort/low-reward were risk factors for RSA (odds ratio[OR]=1.462, 95% confidence interval[CI]: 1.032~2.073; OR=3.253, 95%CI: 1.169~9.053) . A regular work was a protective factor against RSA (OR=0.644, 95%CI: 0.438-0.946) .@*Conclusion@#In occupational stress, irregular working hours, lack of sleep, and high-effort/low-reward are risk factors for RSA. Working women of childbearing age should ensure adequate sleep, pay attention to effort-reward balance, and make a regular work schedule.
ABSTRACT
Objective To study the prevalence and the main risk factors of neonatal asphyxia in southern Gansu province high-altitude area.Method From October 2016 to December 2016,clinical data of neonates born in eight hospitals of the region were analyzed.A uniform questionnaire was used to survey the maternal condition and family background.Univariate and multivariate Logistic regression analysis were used to determine the risk factors of neonatal asphyxia.Result A total of 183 newborns were born with asphyxia (mild 157 cases,severe 26 cases),and the incidence of neonatal asphyxia was 15.3％ (183/1 197).The multivariate Logistic regression analysis indicated that the risk factors included altitude less than 3 000 meters (OR =2.693,95％ CI 1.275 ～5.689),maternal fever (OR =2.986,95％ CI 1.163 ～7.666),prolonged labor (OR =2.925,95％ CI 1.112 ～ 7.691),fetal distress (OR =7.000,95％ CI 3.254 ～ 15.056),uterine inertia (OR =2.737,95％ CI 1.484 ～ 5.047),umbilical cord abnormality (OR =3.094,95％ CI 2.051 ～4.668),amniotic fluid abnormality (OR =2.033,95％ CI 1.230 ～3.361)and placental abnormality (OR =2.753,95％ CI 1.016 ～ 7.464).Annual household income more than 30 000 yuan (OR =0.452,95％ CI 0.297 ～0.687) was protective factor of neonatal asphyxia.Conclusion The incidence of neonatal asphyxia was high in the region,which was related to intrauterine and intrapartum factors.Antepartum monitoring and timely treatment should be strengthened to reduce the incidence of newborn asphyxia.
ABSTRACT
Objective To investigate the distribution of blood lipid of elderly population in high fluorideareas,and compare blood lipid levels in the same age in China.Methods The study used 541 elderly people over 70 years of age who lived in Xiaotangshan for more than 10 years up to 2017.Fasting blood (3 ml) samples were taken,and their cholesterol (TC),triglyceride (TG),high density lipoprotein (HDL) and low density lipoprotein (LDL)were detected,respectively.The results were analyzed and compared with the blood lipid levels of adults over 70 years old in 2010.Results In this study,a total of 541 elderly people over 70 years old,with age of (74.98 ± 4.67)years,were surveyed.There were 246 males,with age of (75.13 ± 4.69) years and 295 females,with age of (74.86 ±4.66) years.The blood TC,TG,HDL and LDL were (4.87 ± 1.07),(1.53 ± 0.93),(1.33 ± 0.31) and (2.60 ± 0.73)mmol/L for the aged people over 70 years old,respectively.The 4 indexes of women over 70 years old were (4.99 ±1.09),(1.67± 1.00),(1.36 ± 0.31) and (2.67 ± 0.75) mmol/L,respectively.Four indicators of women over the age of 70 were higher than those of men [(4.71 ± 1.01),(1.36 ± 0.81),(1.30 ± 0.31),(2.53 ± 0.70) mmol/L,t =3.18,3.95,2.21,2.23,P ＜ 0.05].The levels of blood TC,TG,HDL and LDL were (4.30 ± 1.06),(1.33 ± 1.03),(1.15 ± 0.33)and (2.42 ± 0.78) mmol/L,respectively,in the aged people over 70 years old in the rural areas of China in 2010,and their blood lipid levels were lower than those of people lived in Xiaotangshan area.The differences were statistically significant (t =12.34,5.04,13.80,5.96,P ＜ 0.05).Conclusion We should take health education activities because of the high serum lipid level in high fluoride areas of Xiaotangshan area.
ABSTRACT
This study was designed to investigate the efficacy and safety of endoscopic submucosal dissection [ESD] for treatment of early gastric cancer. In this study, we evaluated the effects of antithrombotic drugs on bleeding risk in patients with ESD. Meta analysis showed that the use of antithrombotic drugs before ESD can reduce the risk of postoperative bleeding, but the early recovery of the use of antithrombotic drugs, or combined with a variety of antithrombotic drugs will increase the risk of bleeding. Twenty-four lesions in 524 patients were treated using ESD, and treatment status and efficacy were observed. Patients received intravenous antibiotics 30 minutes before ESD to prevent infection. If infection occurred after ESD, according to susceptibility test results, patients were given sensitive antibiotics. The one-time en bloc resection rate of all 524 lesions was 100%, and the histologic curative resection rate was 100%. The average time of surgery was 48 min. The rate of mild acute bleeding was 4.2% [22/524], the incidence of postoperative abdominal pain was 54.2% [284/524], and no heavy acute bleeding, perforation, or delayed postoperative bleeding occurred. Endoscopic re-examination at 2 months revealed an ulcer healing rate of 100%. A 12-month follow-up revealed no local residue, relapse, or new lesions. ESD can increase the one-time en bloc resection rate and histologic curative resection rate, and is a safe and effective method for treatment of early gastric cancer

Objective To study the clinical curative effect of dipeptide base peptidase Ⅳ inhibitors (DPP-4) combined with insulin in the treatment of type 2 diabetes.Methods 100 patients with type 2 diabetes were selected as the research subjects,and they were randomly divided into two groups by single blind randomization method,50 cases in each group.The control group adopted the premixed insulin therapy for a month,the observation group received the DPP-4 inhibitors combined with premixed insulin therapy for a month.The blood sugar success rate,weight,incidence of hypoglycemia of the two groups were compared.Results After treatment,the fasting blood glucose value,2 h postprandial blood glucose of the two groups were significantly decreased(t=5.155,P=0.000;t=6.591,P=0.000;t=7.488,P=0.000;t=7.574,P=0.000).But there were no statistical differences between the two groups after treatment (all P>0.05).The incidence rate of hypoglycemic events of the observation group was obviously lower than that of the control group (x2=5.982,P=5.982).Before treatment,the ALT,AST,serum creatinine,urea nitrogen between the two groups had no significant differences(all P>0.05).The body weight,body mass index of the observation group were significantly lower than those of the control group (t=6.931,P=0.000;t=16.010,P=0.000).Conclusion The DPP-4 inhibitor combined premixed insulin therapy for type 2 diabetes has significant hypoglycemic effect,can effectively reduce hypoglycemic events,effectively control the weight,and its effect on liver and kidney function is relatively mild,safe and reliable.
ABSTRACT
Objective To analyze the clinical value of individualized diet therapy in the treatment of gestational diabetes mellitus(DM).Methods The clinical data of 120 patients with gestational DM with individualized diet treatment were retrospectively analyzed.Before and after treatment,the three glycerol(TG),glycosylated hemoglobin(HbAlc),2h postprandial blood glucose(2hPBG),fasting blood glucose(FBG) changes were compared.ResultsThe total effective rate of individual diet therapy was 95.83%.Before treatment,TG,HbAlc,PBG and FBG were (3.28±0.57)mmol/L,(11.59±1.48)% and (12.52±3.32)mmol/L,(10.59±1.60)mmol/L,respectively;which after treatment were (6.49±1.48)mmol/L,(7.01±1.17)% and (7.60±3.08)mmol/L,(1.40±0.51)mmol/L,respectively.The differences between before and after treatment were statistically significant(t=20.856,20.599,9.218,15.961,all P<0.05).Conclusion Individualized diet therapy for gestational DM has significantly clinical effect,can improve the TG,HbAlc,PBG,FBG index,glycemic control,improve the total efficacy,delay the progress of gestational diabetes,improve the outcome of pregnancy.
ABSTRACT
Objective To study the application effect of insulin pump in diabetes treatment.MethodsFrom December 2014 to December 2015,120 diabetic patients in our hospital were selected as the research subjects.The patients were randomly divided into observation group and control group,60 cases in each group.The patients of observation group were treated by insulin pump,and patients of control group were treated with the traditional subcutaneous injection of insulin.The therapeutic effect and adverse reactions of the two groups were observed.ResultsAfter treatment,the two groups had significantly lower in blood sugar.After treatment,the morning fasting blood sugar,2 hours blood sugar after breakfast,2 hours blood sugar after dinner,nocturnal blood sugar of the observation group were (5.13 ±1.05)mmol/L,(6.47±1.23)mmol/L,(5.14 ±1.07)mmol/L,(6.12 ± 1.47)mmol/L,respectively,which were obviously improved compared with the control group (t=10.839 4,11.792 2,10.839 4,11.792 2,all P＜0.05).The total effective rate of the observation group was 96.66％,which was significantly higher than 76.66％ of the control group.The incidence rate of adverse reactions of the observation group was 3.33％,which was significantly lower than 13.33％ of the control group,there was statistically significant differences between the two groups (χ2=7.72,6.72,all P＜0.05).Conclusion Insulin pump in the treatment of diabetes can improve the treatment effect,reduce the incidence of adverse reactions,it is a safe,effective method to treat diabetes,is worth popularizing in the clinical application.
