ABSTRACT
Objective@#To explore the association between Vitamin A, E and mycoplasma pneumoniae pneumonia in children.@*Methods@#153 children with mycoplasma pneumoniae pneumonia and 653 health children were selected as cases and controls, respectively. Propensity score matching (PSM) analysis were conducted to reducing confounding bias between groups. Blood samples were collected to test serum levels of vitamin A and E using high performance liquid chromatography (HPLC). Logistic regression was implemented to determine odds ratios (OR) and 95% confidence intervals (CI) for evaluating the association of mycoplasma pneumoniae pneumonia with the serum levels of Vitamin A and E.@*Results@#After propensity score matching, the study cohort included 153 cases with mycoplasma pneumoniae pneumonia and 306 health children as controls. Before matching, with age and gender adjusted, logistic regression analysis indicated that higher serum levels of Vitamin A and E led to a lower risk of mycoplasma pneumoniae pneumonia (OR=0.075, 95% CI: 0.007-0.815; OR=0.854, 95% CI: 0.792-0.986). After matching, higher serum level of Vitamin E had a significantly lower risk of mycoplasma pneumoniae pneumonia (OR=0.877, 95% CI: 0.810-0.950).@*Conclusions@#The serum levels of Vitamin A didn't have a statistically significant association with mycoplasma pneumoniae pneumonia. However, we observed an obvious association between Vitamin E and mycoplasma pneumoniae pneumonia. Hence Vitamin E clinical monitoring and supplementation are vital for preventing and treating mycoplasma pneumoniae pneumonia.
ABSTRACT
Objective:To investigate the difference of vitamin A and E levels in children with different respiratory diseases at different ages.Methods:A total of 671 children in Hunan Children's Hospital from July 2017 to October 2019 were selected as the disease group, including 197 cases of pneumonia, 152 cases of recurrent respiratory tract infection, 91 cases of asthma, 88 cases of cough variant asthma and 143 cases of Mycoplasma pneumoniae pneumonia; At the same time, 245 healthy children were selected as the normal group. The serum vitamin A and vitamin E levels of the two groups were detected by high performance liquid chromatography (HPLC).Results:⑴ The vitamin A level [(0.31±0.09)mg/L] of the disease group was lower than the normal group [(0.35±0.25)mg/L], and the vitamin E level [(8.92±2.57)mg/L] was lower than the normal group [(9.62±2.79)mg/L], with statistically significant difference ( P<0.05); ⑵ The level of vitamin A in the disease group at the age of >1-3 years [(0.32±0.09)mg/L] was lower than that in the normal group of the same age group [(0.35±0.08)mg/L]; the level of vitamin A in the disease group at the age of >3-6 years old [(0.30±0.08)mg/L] was lower than that of the same age group [(0.32±0.07)mg/L], with statistically significant difference ( P<0.05); ⑶ The vitamin E level of the disease group at >1-3 years old [(9.23±2.56)mg/L], >3-6 [(8.02±1.86)mg/L] and >6-14 years old [(8.02±1.82)mg/L] were lower than that of the same age normal group [(9.76±2.81)mg/L, (9.67±2.87)mg/L, (9.19±2.58)mg/L], with statistically significant difference ( P<0.05); ⑷ There were significant differences in vitamin A levels among different age in disease group ( P<0.05). Among them, the children with high risk of subclinical deficiency accounted for the largest proportion (45.78%) in the 6-month-1-year-old group, and the proportion of children with normal vitamin A levels in other age groups was the largest; ⑸ There are significant differences in vitamin E levels in different age groups in the disease group ( P<0.05), the levels in the normal range accounts for the largest proportion of all ages; ⑹ The levels of vitamin A and vitamin E in mycoplasma pneumoniae infection group were increased compared with in recurrent respiratory infection group , asthma group, and cough variant asthma group, and the difference was statistically significant ( P<0.05). Compared with the pneumonia group, the level of vitamin E increased in the recurrent respiratory infection group, and the difference was statistically significant ( P<0.05); The vitamin E levels in the cough variant asthma group were reduced compared with the repeated respiratory infection group, asthma group and pneumonia group ( P<0.05). Conclusions:The Vitamin A and E levels of children suffering from respiratory diseases are lower than those of normal children. The Vitamin A and E levels of different respiratory diseases and different age groups are different. Vitamin A and E supplementation may be significantly targeted according to different ages and different respiratory diseases in clinical practice.

ABSTRACT
Objective To investigate the clinical effect and safety of kidney transplantation from donors with severe hand-foot-mouth disease (HFMD).Methods Five cases of kidney transplantation from three donors with HFMD between Jan.2014 and Dec.2016 were analyzed.The age of three donors was 2 years,2 years and one month,and 3 years and 11 months respectively,and body weight was 11 kg,10 kg and 15 kg respectively.The age of recipients ranged from 26 to 41 years and weight from 50 to 59 kg.Single kidney transplantations were performed on 4 cases,and dual separating kidney transplantation on one case.Results One case of the transplantations was failure due to the allograft artery thrombosis.The rest 4 cases gained satisfied clinical effect.None of the 5 cases showed any symptoms associated with HFMD.Conclusion The clinical effect of kidney transplantation from donors with severe HFMD is satisfactory.The organs from donors with severe HFMD could only be used by adult recipients.
ABSTRACT
OBJECTIVE@#To investigate the correlation between serum vitamin D levels and index of glucose and lipid metabolism in postmenopausal women with type 2 diabetes mellitus (T2DM).@*METHODS@#A total of 44 postmenopausal women with T2DM and 41 healthy postmenopausal women were matched with age, body mass index and menopausal duration. The serum vitamin D was detected by enzyme-linked immuno-sorbent assay (ELISA).@*RESULTS@#Compared with the control group, the level of 25(OH)D3 in postmenopausal women with T2DM was lower, with no statistical significance. Multiple regression analysis revealed that only BMI(bj'=-0.372, P<0.05) was independently related to 25(OH)D3 with statistical significance. The percentages of 25(OH)D3 deficiency in all subjects in the control group and in the T2DM group were 84.7%, 80.5%, and 88.6%, respectively. The 25(OH)D3 deficiency in the T2DM group was more prevalent than that in the control group, with no statistical difference (P=0.372). The binary logistic regression analysis showed the serum 25(OH)D3 level was not related to the risk of diabetes.@*CONCLUSION@#Compared with the control group, a lower 25(OH)D3 level and a higher rate of 25(OH)D3 deficiency is found in T2DM subjects. When rectified by BMI, these is no significant difference. In postmenopausal women, hypovitaminosis D is associated with obesity and dyslipidemia, but not with the risk of T2DM.
