Objective:To compare the efficacy of body posture combined with pharmacotherapy and pharmacotherapy alone in the treatment of chronic subdural hematoma(CSDH).Methods:Firstly, retrospective case series study was conducted. Thirty cases of CSDH that had received body posture combined with pharmacotherapy at Department of Neurosurgery, Huashan Hospital Affiliated to Fudan University from December 2016 to October 2020 were studied retrospectively. Twenty-seven patients were male, and 3 patients were female. The age of patients ( M(IQR)) was 66(16) years (range:28 to 84). Nineteen patients had unilateral hematoma, and 11 patients had bilateral hematoma. All patients received pharmacotherapy and body posture therapy that was to raise their lower limbs 20 to 30 cm with leg lift pad and get abdominal compressed with customized abdominal belt in supine position. Patients were required to maintain the body posture as much as possible, with the maximum to 16 to 18 hours per day. Patients with unilateral hematoma should tilt the head to the affected side and avoid tilting it to the opposite side. For patients with bilateral hematoma, there was no need for head lateralization. Patient were treated with oral dexamethasone and atorvastatin simultaneously. The preliminary efficacy of body posture combined with pharmacotherapy was determined by hematoma improvement rate which was analyzed by Clopper-Pearson method. Then, the multi-center, prospective, randomized controlled trial had carried out in 9 medical centers from August 2020 to November 2021. The stratified block randomization method was adopted. Patients were randomized in a ratio of 1∶1 to either receive pharmacotherapy alone(the control group) or body posture combined with pharmacotherapy(the experiment group) for 3 months and followed up for 6 months. Effective treatment was defined as complete absorption of hematoma, or the hematoma volume decreased by more than 10 ml and Markwalder grading scale score had improved by more than 1 point compared to the baseline. The efficacy rate and surgery conversion rate at 3 months and recurrence at 6 months were observed. Comparison between groups was performed with paired sample t test, Mann-Whitney U test, χ2 test, corrected χ2 test, or Fisher exact probability method. Logistic regression was used to compare the effective rate and operation rate between the two groups. Results:In the respective study, 30 patients completed follow-up 13 to 353 days after treatment. At the last follow-up, the incidence of almost complete absorption or significantly absorption of hematoma (hematoma volume was significantly reduced accompanied by symptom improvement) was 93.3%. The 95% CI for the incidence that analyzed by the Clopper-Pearson method was 77.9% to 99.2%. One hundred and six patients were enrolled in the multicenter study. Fifty-five patients underwent body posture combined with pharmacotherapy. The age was 74(17) years (range:26 to 92). Thirty-nine patients were males and 16 were females. Fifty-one patients underwent pharmacotherapy alone. The age was 69(12) years (range:48 to 84). Thirty-seven patients were males and 14 were females. The length of body posture recorded in diary card was (15.7±2.3) hours(range:7.6 to 19.3 hours). The efficacy rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 83.6% (46/55) and 56.9% (29/51), respectively at 3 months. The result of the logistic regression analysis showed that the efficacy of body posture combined with pharmacotherapy group was better than that of pharmacotherapy alone group ( OR=3.88,95% CI:1.57 to 9.58, P=0.003). Surgery rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 5.5% (3/55) and 21.6% (11/51) respectively. The result of Logistic regression showed that the pharmacotherapy alone group was more likely to be converted to surgery ( OR=0.21,95% CI:0.05 to 0.80, P=0.023). At the 6 months, no recurrence of cases was found in the body posture combined with pharmacotherapy group. However, the recurrence rate of pharmacotherapy alone group was 6.3% (3/48), there was no significant difference between the two groups ( P>0.05). Conclusion:The effect of body posture combined with pharmacotherapy for chronic subdural hematoma is better than that of pharmacotherapy alone.

【Objective】 To investigate the association between the long-stranded non-coding ribonucleic acid (lncRNA) MRAK088388 and allergic asthma in children. 【Methods】 A total of 15 healthy children and 15 children with asthma were monitored for disease progression over a 2-year period. Blood samples were collected from patients during the chronic phase of the disease for lncRNA/mRNA expression microarray analysis. Competing endogenous RNA networks (MRAK088388/miR-30a/ATG5) were identified by bioinformatics analysis. In vitro cultured bronchial epithelial (16HBE) cells were used to quantify gene and associated protein expression levels by real-time fluorescent quantitative polymerase chain reaction (qPCR) and protein blotting, respectively. Cell Counting Kit-8 and transwell assays were used to assess the proliferation and migration of 16HBE cells and verify the effects of MRAK088388, miR-30a and ATG5 on asthma. 【Results】 Six lncRNA-miRNA-mRNAs were identified by correlation analysis. By qRT-PCR analysis, MRAK088388/miR-30a/ATG5 was selected to construct the ceRNA network in this study. mRAK088388 and ATG5 expressions were high in the peripheral blood of children with asthma, while the expression of miR-30a was low (P<0.05). The expression level of E-cadherin was significantly higher in 16HBE cells after si-MRAK088388+TGF-β1 group, while the expression levels of Vimentin and α-SMA were significantly lower (P<0.05), indicating that knockdown of MRAK088388 inhibited the epithelial mesenchymal transition in 16HBE cells. Compared with si-NC+ TGF-β1 group, the cell morphology of si-MRAK088388+TGF-β1 group was similar to that of the control group, indicating that MRAK088388 knockdown attenuated TGF-β1-induced cell morphological changes; in addition, MRAK088388 knockdown inhibited TGF-β1-induced proliferation and migration of 16HBE cells. MRAK088388 was confirmed by qPCR and protein blotting to promote the progression of childhood asthma by targeting the miR-30a/ATG5 axis. 【Conclusion】 Childhood asthma is associated with the MRAK088388/miR-30a/ATG5 axis, and MRAK088388 is involved in the process of childhood allergic asthma by negatively regulating miR-30a expression and regulating elevated ATG5 expression levels to affect bronchial epithelial cell mesenchymal transition, proliferation, and migration.

Objective To investigate the long non-coding RNA(lncRNA) MRAK08838 regulates macrophage function to influence the development of asthmatic airway inflammation. Methods MRAK088388 gene knockout (MRAK088388^-/-) mouse model was prepared and allergic asthma was induced by dust mite protein Dermatophagoides farinae 1 (Der f1). The mice were sacrificed after 28 days of modeling, and serum was collected to measure IgE and IgG. The FinePointe RC system was used to measure airway hyperresponsiveness and evaluate lung function in mice. Lung tissue was taken for HE staining, and periodic acid-Schiff (PAS) staining was used to evaluate inflammatory infiltration and mucus secretion in mouse lungs. Fluorescence quantitative PCR was used to detect the expression level of lncRNA MRAK08838 in bronchoalveolar lavage fluid (BALF) cells and lung tissue of asthmatic mice. ELISA was used to detect the levels of inflammatory cytokines IFN-γ, IL-4, IL-5, IL-13, IL-10 and IL-17A. Flow cytometry was used to evaluate the phenotype of macrophages in BALF and lung tissue, as well as the proportion of neutrophils, eosinophils, and alveolar macrophages. The changes of the above indicators were detected in mice by adoptive transfer of bone marrow-derived macrophages (BMDM). Results Under the challengle of Der f1, MRAK088388^-/- mice showed reduced allergic airway inflammation, including reduced eosinophils in BALF and reduced production of IgE and IgG1. In addition, Der f1-treated MRAK088388^-/- mice had fewer M2 macrophages than wild-type asthmatic mice. Wild-type mouse BMDM (M0) and Der f1-treated MRAK088388^-/- mice also showed mild inflammatory response. Conclusion Knockout of MRAK088388 alleviates airway inflammation in asthmatic mice by inhibiting M2 polarization of airway macrophages.

Objective:To assess the trend and the factors responsible for the increase of life expectancy of residents in Tianjin over the past two decades.Methods:Abridged Life Table and Arriaga's decomposition method was applied to quantify the influence of the age structure and the leading causes of death on the increase of life expectancy of residents in Tianjin from 1999 to 2018.Results:In the past 20 years, the life expectancy of residents in Tianjin increased by 4.97 years, the life expectancy of men and women increased by 4.11 years and 5.86 years, respectively. The decrease of mortality rate in 0-year-old group contributed 19.17% to the increase of the life expectancy, while the decrease of mortality rate in residents aged ≥55 years contributed more to the increase of life expectancy, with the cumulative contribution rate of 67.38%. The major contribution to the increase of life expectancy was the mortality reduction of cerebrovascular disease, respiratory disease, cardiovascular disease, perinatal diseases, congenital malformations and injury, with the contribution percentage of 27.27%, 21.37%, 15.76%, 12.22%, 6.44% and 4.86%, respectively. The increase of mortality of malignant tumor, injury and poisoning, diabetes and nervous system diseases and others had a negative effect on the increase of life expectancy of people aged ≥75 years. From 1999 to 2018, the life expectancy increased from 76.72 years to 81.46 years ( t=9.11, P<0.001), the annual percent change (APC) was 0.58%. From 2011 to 2018, it was stable, ranging from 81.46 years to 81.69 years ( t=0.89, P=0.387, APC=0.13%). Conclusion:From 1999 to 2018, the increase of life expectancy was attributed to the decrease of mortalities in infants and the elderly and the decrease of mortalities of cerebro-cardiovascular disease, respiratory disease, perinatal disease, congenital malformations and injury. However, these positive contributions were partly offset by the negative contribution of malignant tumor, injury, diabetes and nervous system disease in those aged ≥75 years. Comprehensive prevention and control of key diseases should be strengthened in key population in order to further improve the life expectancy of the population.

Objective To explore the diagnostic value of ESWAN in uterine fibroids by analyzing the ESWAN signal of uterine fibroid. Methods Conventional MRI and ESWAN were carried out in thirty-seven patients with uterine fibroids.The differences of ESWAN indexes between uterine fibroids and myometrium were analyzed by paired t-test.The value of ESWAN on diagnosing uterine fibroids was analyzed by receiver operating characteristic curve(ROC curve).Results The magnitude value,phase value,R2* value and T2*value of uterine fibroids were 1 661.69 ± 45.24,(0.006 7 ± 0.007 7)Hz,(26.69 ± 1.04)Hz and(34.68 ± 1.73)ms,respectively.The magnitude value,phase value,R2* value and T2* value of myometrium were 1 790.95 ± 49.04,(0.013 1 ± 0.011 8)Hz,(22.35 ± 0.84)Hz and(42.53 ± 2.16)ms.The magnitude value,phase value and T2* value of uterine fibroids were lower than those of myometrium (P=0.008,P=0.659 and P=0.002).While the R2* value of of uterine fibroids was higher than that of myometrium(P=0.001). The area under curve(AUC)of magnitude value,phase value,R2* value and T2* value were 0.604,0.553,0.666 and 0.662.Conclusion ESWAN can show the differences between uterine fibroids and myometrium ，while the ability to independently diagnose uterine fibroids was modest.
