Objective To investigate vitamin D nutrition of children aging 0-6 years who received routine physical checkup in outpatient clinic,and to provide evidence for supplementation of vitamin D.Methods A total of 3 724 children were enrolled in children healthcare outpatient clinic in the Maternity and Child Health Care Hospital of Huzhou from January 2013 to March 2014.Serum 25-hydroxy vitamin D [25-(OH) D] levels of the children were measured using electrochemiluminescence to compare serum 25-(OH) D levels and vitamin D deficiency in children of different ages and in seasons.Results The mean 25-(OH) D level in these children was (37.80 ± 11.67) ng/ml,and the prevalence of vitamin D deficiency was 7.33％,neither showing significant difference between boys and girls (t =-1.57,P =0.117 ; x2 ＝ 0.37,P =0.543).The serum 25-(OH) D level in ＞3-and-≤6 years group was remarkably lower than the levels in ≤1 year,＞ 1-and-≤2 years and ＞2-and-≤3 years groups [(27.36 ±8.90) ng/ml vs.(38.64 ± 12.10) ng/ml,t =18.60,P=0.000;vs.(41.63±10.31) ng/ml,t=26.07,P=0.000;vs.(36.85±10.01) ng/ml,t=16.42,P =0.000],and the prevalence of vitamin D deficiency significanl higher than those in the other 3 age groups (104/466 vs.122/1 487,x2 =69.06,P =0.000; vs.18/1 106,x2 =196.06,P =0.000; vs.29/665,x2 =85.14,P =0.000).The serum 25-(OH) D level in children in winter was significantly lower than in spring,summer,and autumn [(35.16 ± 11.30) ng/ml vs.(40.03 ± 12.57) ng/ml,t =9.15,P =0.000;vs.(36.86±10.60) ng/ml,t=3.34,P=0.001; vs.(39.99±11.36) ng/ml,t=9.65,P=0.000],and the prevalence of vitamin D deficiency significantly higher than in the other 3 seasons (127/1 189 vs.56/ 849,x2 =10.11,P =0.001; vs.54/787,x2 =28.30,P=0.004; vs.36/899,x2 =31.71,P=0.000).Conclusions Vitamin D nutrition status of infants at 0-6 years in our child healthcare outpatient clinic is generally good,except for lower vitamin D level and higher prevalence of vitamin D deficiency in winter and ＞3-and-≤6 years age group.Therefore,vitamin D supplementation in winter and in children above 3 years old is especially important.Recommendations include more outdoor activities and public education for scientific prevention of vitamin D deficiency.

Objective To investigate the prevalence of thyroid diseases in women within 20-week gestation,and to discuss necessity of thyroid diseases screening in women within 20-week gestation.Methods 4986 singleton pregnant women performing prenatal examination in the Maternity and Child Health Care Hospital of Huzhou were recruited into this study.TSH,FT4,and TPOAb levels were detected with ABBOTT ARCHITECT i4000SR.Results ① The median value of TSH rised,the median value of FT4 went down with increase of the gestational weeks.There was significant difference of median value of TSH and FT4 between early and second trimester of pregnancy(P＜0.01).② Rate of abnormal thyroid function was 12.88％,which was higher in the sec ond trimester of pregnancy than that in early pregnancy,and the difference had statistical significance (P＜0.05).③ Positive rate of TPOAb in pregnant women was 11.41％.TPOAb levels were positively correlated with TSH,and no correlation with FT.TSH levels were negatively correlated with FT4.Prevalance of clinical hypothyroidism and subclinical hypothyroidism in TPOAb positive group was significantly higher than that in TPOAb negative group,and the difference had significant difference (P＜0.05).Conclusions Prevalence of thyroid diseases during pregnancy is high.TPOAb is a risk factor and important predictor for hypothyroidism during pregnancy.It is very necessary to perform thyroid diseases screening for pregnant women as early as possible to ensure safety of pregnant women and their babies.

Objective To evaluate the diagnostic accuracy of half-Fourier single-shot TSE MR cholangiopancreatography (HASTE-MRCP) of 0.5 T MR scanner, and to assess its imaging advantage and clinical value by comparing with 3D-TSE-MRCP MIP. Methods All 95 patients were examined by HASTE-MRCP and 3D-TSE-MRCP with respiratory-triggering (Philips 0.5 T T5-NT). The results, including anatomies and diseases, were evaluated after operation. Results By HASTE-MRCP, common bile ducts, 1-3 branches of hepatic ducts, gallbladder, and pancreatic ducts were demonstrated in 100.0%, 94.7%, 74.1%, and 63.2% of the cases. Stones, malignant diseases, and postoperative stenosis were revealed in 100.0% of the cases. Compared with 3D-TSE-MRCP, the demonstrating rates of 4-5 hepatic ducts,neck of the gallbladders,and calculi,especially mud calculi, were higher in HASTE-MRCP, and there was significant difference between the two ways. Stones displayed as low signal in the bile ducts. Block obstruction and mass contour were revealed in malignant diseases. Conclusion Comparing with 3D TSE-MRCP, HASTE-MRCP was better and faster, especially in serious patients or in cases with small and mud calculus.

ObjectiveTo investigate the expression of miR-21 in diffuse large B cell lymphoma (DLBCL)and normal lymph tissues and its potential relevance with clinicopathological characteristics.MethodsThe expression levels of miR-21 in 50 primary DLBCL and 12 normal lymph node tissue specimens were examined by TaqMan real-time polymerase chain reaction.The expression of bcl-2 and p53 was detected by immunohistochemistry staining. ResultsThe expression of miR-21 was significantly higher in tumor tissues than that in normal tissues, in GCB subtypes higher than in non-GCB subtypes. And it was negatively correlated with bcl-2(P=0.020),while positively correlated with p53(P=0.022). Up-regulated miR-21 expression was low in three years of survival rate. ConclusionMiR-21 may indicate a more aggressive phenotype and serve as a molecular prognostic marker in DLBCL. High-expression of miR-21 is a key feature that is correlated with cell proliferation in DLBCL.miR-21 may have some guiding significance in prognosis.bcl-2,p53 is possibly one of the targets of miR-21 in DLBCL.

Objective: To understand health literacy and associated factors of freshmen from Jiangsu Province, and to provide reference for youth health education. Methods: From 2017 October to 2018 October, a total of 15 602 college freshman were randomly selected from 20 universities in Jiangsu Province via stratified cluster sampling method. Structural questionnaires were used to investigate the status of health literacy. The χ 2 test and multivariate Logistic regression model were used to analyze the influencing factors of health literacy. Results: The health literacy level of college freshmen from Jiangsu Province was 20.2%, among which the literacy levels of knowledge, behavior and skills were 23.0%, 30.7% and 31.5% respectively. The literacy levels of the six public health issues, including safety and first aid, scientific health attitude, knowledge of prevention and treatment of infectious diseases, health information, basic health care, and prevention and treatment of chronic diseases, from high to low, were 72.8%, 58.7%, 28.5%, 28.2%, 20.3% and 15.9%, respectively. Multivariate Logistic regression analysis has showed that students from undergraduate colleges(OR=2.77, 95%CI=2.47-3.11), urban areas(OR=1.20, 95%CI=1.07-1.34), or southern Jiangsu regions(OR=1.10, 95%CI=1.00-1.22), being the only child(OR=1.13, 95%CI=1.03-1.25), higher maternal education level (OR=1.53, 95%CI=1.30-1.79), having both parents(OR=1.16, 95%CI=1.00-1.34), reported higher level of health literacy. Conclusion The three aspects and six dimensions of health literacy of college freshmen were unbalanced. Health literacy is a shared function of multiple factors including society, family, and individuals. It is essential to promote health education through more efforts on key issues, in order to effectively elevate the health literacy level of adolescent students.

OBJECTIVE: To explore the effect of community nursing intervention on awareness regarding primary prevention knowledge, self-management, and risk factors for coronary heart disease (CHD) in Hengyang City, Hunan Province. METHODS: A total of 120 individuals at high risk of CHD were recruited and divided into a control group and an intervention group. The intervention group was given the health knowledge lecture and individual community nursing intervention. The control group was given the routine management. Before and after the intervention, all of the recruiters were evaluated by the awareness on primary prevention knowledge, self-management and risk factors for CHD. RESULTS: Before the intervention, there was no significant difference in the demographic data, the cognitive levels regarding primary prevention knowledge, the self-management and the risk factors for CHD between the 2 groups (P>0.05). After the intervention, the cognitive levels regarding primary prevention knowledge, the self-management and the risk factors for CHD between the 2 groups changed. In the intervention group, the cognitive level was significantly increased (P<0.05); the self management score was improved; the systolic blood pressure, BMI, and the levels of fasting glucose, TC and low density lipoprotein-cholesterol were significantly decreased and the level of high density lipoprotein-cholesterol was significantly increased (P<0.05). There was no significant difference in the above-mentioned parameters between before and after intervention in the control group (P>0.05). CONCLUSION The cognitive levels regarding primary prevention knowledge and self-management for CHD can be improved effectively by community nursing intervention in high-risk population of CHD, and the risk factors for CHD can also be reduced.

Objective To investigate the distribution of methyleneterahydrofolate reductase (MTHFR) C677T gene polymorphisms and serum homocysteine (Hcy) levels in pregnant women. Method A total of 2 066 women with singleton pregnancies undergoing prenatal examinations in the Maternity and Child Health Care Hospital of Huzhou from January 2017 to October 2017 were recruited for the study.The MTHFR C677T genotype was detected by PCR-fluorescence probing, and the serum Hcy levels were detected by the cyclic enzyme method. According to the MTHFR C677T genotype detection analysis, the results were divided into the CC-type, CT-type, and TT-type groups. Statistical analyses were performed using the Hardy-Weinberg genetic equilibrium test, chi-square test, variance analysis, and t test. Result Among the 2066 pregnant women, the CC, CT, and TT genotype frequencies for the MTHFR C677T gene were 39.35%,46.52%,and 14.13%,respectively.The Cand T allele frequencies were 62.61% and 37.39%, respectively. The statistical significance values for the Shanxi, Zibo, Shanghai, Suzhou, Shangzhi, Xi'an, Huizhou, and Nanning areas were as follows: χ2=161.999, 166.083; 111.005, 112.517; 416.146, 441.245;14.262,14.23;36.368,35.871;199.498,204.771;19.641,16.377;and 66.79,61.593,respectively;P<0.05. The level of serum Hcy was(7.48±2.20)μmol/L,and the abnormal rate was 3.53%.The level of serum Hcy and the abnormal rate among the 3 genotypes were distributed as follows: TT>CT>CC. The difference was statistically significant(F=120.968, χ2=52.572, P=0.000). Conclusion The distribution of genotype frequencies for MTHFR C667T in 2 066 pregnant women was different in various geographical regions.The level of serum Hcy was associated with the MTHFR C677T gene. Observing MTHFR C677T gene polymorphisms and serum Hcy levels is helpful for monitoring and guiding folic acid supplementation during pregnancy,and establishing reasonable individual health preventive measures.It is an important method to improve the quality of life of the offspring and the family happiness index.
