Co-occurrence trend of overweight,obesity and elevated blood pressure and its association with lifestyle factors among students in Inner Mongolia Autonomous Region / 中国学校卫生

Objective@#To explore the epidemiological trend of overweight and obesity, elevated blood pressure and their comorbidities in children and adolescents from Inner Mongolia Autonomous Region during 2016-2021, and to analyze its association with lifestyle, so as to provide reference for formulating prevention and control strategies of regional common comorbidities in schools.@*Methods@#A total of 8 908, 8 222, 9 448, 127 068, 100 778, and 138 540 students aged 10-18 years in Inner Mongolia were selected by stratified random cluster sampling in September each year from 2016 to 2021. Physical examination and questionnaire survey were conducted on the included students. The prevalence trends of overweight，obesity, elevated blood pressure and their co-occurrence were analyzed. Logistic regression was used to compare the prevalence of elevated blood pressure in different body mass index (BMI) groups. After excluding individuals without lifestyle information in 2021, Logistic regression analysis was used on 136 374 subjects to analyze the association between overweight，obesity, elevated blood pressure and their co-occurrence and lifestyle factors.@*Results@#During 2016 to 2021, the prevalence of comorbidity of overweight, obesity with elevated blood pressure among students in Inner Mongolia Autonomous Region were 5.04%，5.14%，4.99%，7.51%，7.60% and 9.45%， respectively . The prevalence of overweight and obesity was 26.94%, 28.07%, 29.62%, 34.19%, 36.71% and 37.53%, respectively. The prevalence of elevated blood pressure were 16.05%, 11.54%, 13.12%, 14.85%, 14.12% and 18.40%, respectively. Except for 2016, the risk of elevated blood pressure in overweight and obese people was higher than that in normal BMI group in other years, and there was a positive correlation between overweight and obesity and elevated blood pressure after gender and urban and rural areas ( P < 0.05 ). In 2021, the detection rate of comorbidity of overweight and obesity with elevated blood pressure among children and adolescents in urban areas was higher than that in suburban counties, and the reporting rate of healthy lifestyle was lower than that in suburban counties ( P <0.05).Skipping breakfast ( OR =1.11，95% CI =1.07-1.16) and non daily moderate and high intensity physical activity( OR =1.27，95% CI =1.20-1.34) were positively correlated with the co-occurrence of overweight，obesity and elevated blood pressure among children and adolescents in Inner Mongolia Autonomous Region. Non daily moderate and high intensity physical activity ≥60 min was positively correlated with elevated blood pressure ( OR =1.11，95% CI =1.07-1.16), and insufficient sleep was positively correlated with overweight，obesity ( OR =1.04, 95% CI =1.01-1.06)（ P ＜0.05）.@*Conclusion@#The prevalence of overweight，obesity, elevated blood pressure and their co-occurrence among children and adolescents in Inner Mongolia Autonomous Region is relatively high. Overweight/obesity is an important risk factor for elevated blood pressure, and unhealthy lifestyles are risk factors for co-occurrence of overweight，obesity and elevated blood pressure. Region specific lifestyle interventions are indispensable for the prevention and control of regional common comorbidities. Urban areas may be a key focus for lifestyle interventions.

Prenatal diagnosis of a fetus with chromosome 18p deletion and duplication / 中华医学遗传学杂志

OBJECTIVE@#To assess the value of chromosomal microarray analysis (CMA) to verify a fetus with partial 18p deletion signaled by non-invasive prenatal testing.@*METHODS@#G-banding chromosomal karyotyping analysis was carried out on amniotic fluid sample of the fetus and peripheral blood samples from the parents. Amniotic DNA was also subjected to CMA analysis. The fetus was also subjected to systematic ultrasound scan.@*RESULTS@#The fetus was found to have a karyotype of 46,XX,18p+. CMA has revealed a 5 Mb deletion at 18p11.32-p11.31, a 2.9 Mb duplication at 18p11.31-p11.23, and a 2.5 Mb duplication at 18p11.23-p11.22. No chromosomal aberration or microdeletion/microduplication was detected in either parent.@*CONCLUSION@#Non-invasive prenatal testing and CMA are both sensitive for the detection of chromosomal microdeletions and microduplications. CMA can help with clarification of genotype-phenotype correlation and facilitate prenatal diagnosis and genetic counseling for the family.

Effects of Mycobacterium tuberculosis HSP65 on Treg/Th17 immune balance in ApoE-knockout mice / 中国药科大学学报

@#To investigate the effects of Mycobacterium tuberculosis heat shock protein 65(HSP65)on Treg/Th17 immune balance in ApoE-knockout(ApoE-/-)mice, ApoE-/- mice with a high-cholesterol diet were immunized with M. tuberculosis HSP65. Sera were obtained for measurement of anti-HSP65 antibodies by ELISA; the effect of administration of different antigens was investigated, respectively, using flow cytometry analysis on the number of CD4+CD25+Foxp3+Tregs and CD4+IL-17+ Th17; the production of cytokines(IL-10, TGF-β1, IL-17 and IL-21)by these cells were determined by ELISA; total plasma cholesterol(TC), triglyceride(TG), high-density lipoprotein cholesterol(HDL-C)and low-density lipoprotein cholesterol(LDL-C)levels were detected by biochemical autoanalyzer. Atherosclerotic lesions were measured by lipid deposition stained with oil red O. The results demonstrated that the levels of anti-HSP65 IgG antibodies were increased significantly in Mycobacterium tuberculosis HSP65-treated ApoE-/- mice, revealed obvious decrease in Treg number, Treg related cytokines(IL-10, TGF-β1)levels and significant increase in Th17 number, Th17 related cytokines(IL-17 and IL-21)levels, the levels of TC, TG, HDL-C and LDL-C did not change between groups, while the atherosclerotic lesions significantly increased. Results indicate that M. tuberculosis HSP65 could interrupt the Th17/Treg immune balance in ApoE-/- mice, suggesting a potential role in the formation and progression of atherosclerosis.

Objective To explore the effect and complication of synchronized intermittent mandatory ventilation (SIMV) combined with pressure support ventilation (PSV) and targeted tidal volume (TTV) in treatment of neonatal respiratory distress syndrome(NRDS).Methods Fifty-three neonates with severe NRDS between Jan.2010 and Dec.2012 were randomly assigned to 2 groups according to the ventilation mode:SIMV + PSV + TTV group (n =27),and assist/control group (A/C group) (n =26).The oxygenation status,the durations of oxygen exposure and ventilation and the incidence of complications were observed.Results The oxygenation status arterial oxygen partial pressure/fraction of inspired oxygen (P/F),arterial oxygen partial pressure/alveolar O2 tension(a/APO2) in the SIMV + PSV +TTV group were significantly improved at 6 h after ventilation (t =9.393,4.856,all P ＜ 0.05) ;and compared with A/ C group,they were significantly improved at 6 h (t =6.132,2.805,all P ＜ 0.05),24 h (t =2.890,2.682,all P ＜0.05),72 h (t =3.804,4.053,all P ＜ 0.05) after ventilation in the SIMV + PSV + TTV group.The incidences of air leak syndrome and ventilation-associated pneumonia(VAP) were lower in the SIMV + PSV + TTV group than those in the A/C group(t =3.908,4.178,all P ＜ 0.05).There were no significant differences in the mortality between the two groups (t =0.534,P ＞ 0.05).Conclusions Compared with A/C,SIMV + PSV + TTV can improve the oxygenation status more quickly,and decrease the incidences of air leak syndrome and VAP in neonates with severe RDS.

Functions and mechanisms of long non-coding RNAs in lung cancer / 中国肿瘤临床

Long non-coding RNAs (lncRNAs) are non-coding RNAs that have transcript lengths exceeding 200 bp and do not have the capacity for protein coding because of having no open reading frame. In the human genome, lncRNAs play important regulato-ry roles in the process of epigenetic, transcription and post-transcription, so they have become the focus of research followed by mi-croRNAs. The abnormal expression of lncRNAs in cancer usually represents different functions, such as the function of oncogenes or tumor suppressor genes, which promote or inhibit tumor growth. Lung cancer is a common malignant tumor with a five-year survival rate of 17%. Previous literature shows that MALAT1, H19, lincRNA p21, UCA1, and BC200 are closely related to the development of lung cancer. They could promote cancer growth, invasion and metastasis, apoptosis and induce drug resistance, and so on. This review aims to provide assistance in the diagnosis, treatment, and prognosis of lung cancer by clarifying the functions and mechanisms of ln-cRNAs.

Change of matrix metalloproteinase-9 in rats with multiple organ dysfunction syndrome / 中华急诊医学杂志

Objective To investigate the changes in the serum MMP-9 (matrix metalloproteinase-9) and the expressions of MMP-9 in lung, kidney and intestine in rats with multiple organ dysfunction syndrome (MODS) and confirm extracellular matrix injuries being the mechanism in MODS in order to propose a novel theoretical basis for cfinical treatment of MODS. Method Forty wister rats were randomly divided into two groups: control group (n=8) and MODS model group (n=32). The rats of model group were further divided into four subgroups ac-cordingto the time elapsed after modelling: 12 h (n=8), 24 h(n=8) ,48 h(n=8) and 72 h (n=8), and were modelled by celiac injection of mixed liquid of zymosan-paraffin (4 mL/100 g) after blood loss (1mL/100 g) by extirpating their left eyes. Blood,lung, kidney and intestine were sampled 12,24,48 and 72 hours after models were established. The histological changes in the lung, kidney and intestine of the rats were observed by light mi-croscope. The serum MMP-9 were measured by enzyme-linked immunosorbent assay (ELISA). The immunohisto-chemistry was used to observe the expression of MMP-9 in lung,kidney and intestine during different phases of MODS. The data were processed by one-way ANOVA and Bivariate analysis. Results Compared with control group, the organs were injured by congestion, edema and inflammatory cells infiltration to a certain extent in model groups. The serum MMP-9 increased markedly 12 hours after modelling (P<0.01 ) and peaked 48 hours later. The expressions of MMP-9 in lung, kidney and small intestine significantly increased from 12 h to 72 h after mod-elling (P<0.01 or 0.05). Conclusions The MMP-9 increased both in serum and tissue are closely associated with the pathological process of MODS. The mechanism of organ damage probably attributes to the damage of extra-celluar matrix and tissue construction.
