RBC, plasma and hair Mn levels have been measured in 38 children with Keshan disease from the Chuxiong district of Yunan province and were compared with that of 35 healthy children. After logarithmic, transformation, normal distribution of Mn levels of RBC, plasma and hair had been presented. The geometric means of the RBC, plasma and hair Mn content of the patients were 1.22?g/g(dry basis), 0.16?g/ml and 8.76?g/g respectively. In normal subjects, the means of RBC, plasma and hair Mn were found to be 0.59?g/g (dry basis), 0.13?g/ml and 2.57?g/g. The children with Keshan disease had higher Mn levels than controls. (P

Objective:To analyze the clinical characteristics of children with 2019 novel coronavirus (2019-nCoV) infection in Putian City, and to provide a reference for the diagnosis and treatment of children with 2019-nCoV infection.Methods:Clinical characteristics, laboratory examination, pulmonary compated tomography findings, treatment, and clinical outcomes of 78 children with 2019-nCoV infection who were admitted to Putian University Affiliated Hospital Medical Group Putian City Children′s Hospital from September 10 to October 20, 2021 were retrospectively collected and analyzed.Results:Of the 78 children included in the analysis, two cases (2.6%) were asymptomatic infection, 36 cases (46.2%) were mild and 40 cases (51.3%) were ordinary. Five children were vaccinated against 2019-nCoV. The main symptoms were fever (24 cases), cough (13 cases), and fatigue (nine cases). A total of 34 cases (43.6%) had neutropenia, 29 cases (37.2%) had lymphopenia, 36 cases (46.2%) had D-dimer increase, 38 cases (48.7%) had hypokalemia, 27 cases (34.6%) had hypoglycemia and 11 cases (14.1%) had elevated creatine kinase isoenzyme. The neutropenia mostly occurred two to four days after admission. Fifty-six cases (71.8%) showed pulmonary computed tomography abnormalities. The cycle threshold of virus open reading frame ( ORF)1 ab was 20.90±7.15 and the cycle threshold of N gene was 20.29±7.78 in the first nucleic acid detection of 78 children after admission. The time of nucleic acid negative conversion of the 78 children was (20.73±6.94) days. IgM antibody titer in five vaccinated children was 0.36 (0.34, 4.89) and IgG antibody was 10.42 (0.50, 19.42). IgM antibody titer was 1.82 (1.66, 8.12) and IgG antibody was 76.63 (16.92, 79.84) in cases with disease duration ≥10 days. Nine children (11.5%) had resurgence of virus and were sent to the isolation site. All the other children were cured and discharged from hospital. Conclusions:Children with 2019-nCoV infection have mild clinical symptoms, and some children have lymphopenia, neutropenia, and D-dimer elevation during the course of the disease. The overall prognosis is good. The children vaccinated against 2019-nCoV have higher antibody levels.

【Objective】 To investigate the control rate of blood glucose and its influencing factors in type 2 diabetes mellitus patients in Yulin area. 【Methods】 We selected the adult type 2 diabetes patients who visited our hospital from May 2020 to December 2021 as the subjects. Then we collected their basic information (gender, age, household income, type of medical insurance payment, education level, and duration of disease), measured their height and weight, calculated their body mass index (BMI), detected HbA1c, and measured their subcutaneous and visceral fat. The Chi-square test and multivariate Logistic regression methods were used to analyze the influencing factors. 【Results】 The total attainment rate of HbA1c (HbA1c<7%) among 877 adults with type 2 diabetes was 13.34%. The Chi-square test showed that statistical differences in the attainment rate of HbA1c among different ages, family annual income, type of medical insurance, and duration of disease. Further unconditional multivariate Logistic regression analysis model results showed that the HbA1c attainment rate in 18-44 years old group was 0.418 times higher than that in ≥60 years old group (95% CI=0.219-0.799, P=0.008). The HbA1c compliance rate of patients with employees’ medical insurance was 1.744 times that those with residents’ medical insurance (95% CI=1.131-2.782, P=0.013). The HbA1c attainment rate of diabetic patients with an annual family income of 30 000 yuan to 100 000 yuan was 1.873 times (95% CI=1.074-3.266, P=0.027), and with an annual family income of more than 100 000 yuan was 2.649 (95% CI=1.299-5.404, P=0.007) times than that of diabetic patients with less than 30 000 yuan. 【Conclusion】 The blood glucose control rate in adults with type 2 diabetes mellitus in Yulin area is lower compared with the level of the nation and other regions. Age, annual household income, and type of medical insurance payment are independent influencing factors.

【Objective】 To investigate the practice and benefit of national standardized management of type 2 diabetes in Yulin City. 【Methods】 We recruited the adult type 2 diabetes patients who sought medical help at our hospital from May 2020 to October 2022 as subjects. We collected their basic information (sex and age); measured height, weight, waist and hip circumference, and blood pressure; calculated body mass index (BMI); and detected blood glucose, c-peptide, HbA1c, biomarkers, urinary microalbumin, sensory nerve conduction velocity of lower limbs, ABI, and subcutaneous and visceral fat at the time of MMC recruited and the end of six months. T test and Mann-Whitney U rank sum test were used for measurement data and χ² test or Fisher’s exact probability method for counting data to analyze the data. 【Results】 After 6 months, the levels of fasting blood glucose, postprandial blood glucose, HbA1c, and visceral and subcutaneous fat in all the patients decreased, but the level of fasting c-peptide increased compared with the baseline (all P<0.05). Secondly, compared with the baseline, the control rate of HbA1c (35.21% vs. 13.71% ) and the comprehensive control rate (13.97% vs. 7.26% ) were both significantly increased at six months (P<0.05). Thirdly, after 6 months, the levels of fasting blood glucose, postprandial blood glucose, HbA1c, TG, TC, and UA were decreased more, while the fasting c-peptide and postprandial c-peptide were increased more in the patients of the HbA1c standard group (HbA1c<7% ) than those of the non-standard group. 【Conclusion】 The multiple benefits of blood glucose, blood lipid, uric acid and islet function can be achieved by taking type 2 diabetes patients into MMC. Meanwhile, the rates of HbA1c control and comprehensively reaching the standard are significantly increased. Therefore, MMC can explore a new way for the management of type 2 diabetic patients in this area.
