		                        			The mechanisms underlying exercise-induced neuroprotective effects after traumatic brain injury (TBI) remained elusive, and there is a lack of effective treatments for TBI. In this study, we investigated the effects of an integrative approach of exercise and Yisaipu (TNFR-IgG fusion protein, TNF inhibitor) in a mouse TBI model. Male C57BL/6J mice were randomly assigned to a sedentary group or a group that followed a voluntary exercise regimen. The effects of 6-week prophylactic preconditioning exercise (PE) alone or in combination with post-TBI Yisaipu treatment on moderate TBI associated deficits were examined. The results showed that combined treatments of PE and post-TBI Yisaipu were superior to single treatments on reducing sensorimotor and gait dysfunctions in mice. These functional improvements were accompanied by reduced systemic inflammation largely via decreased serum TNF-α, boosted autophagic flux, and mitigated lesion volume after TBI. Given these neuroprotective effects, composite approaches such as a combination of exercise and TNF inhibitor may be a promising strategy for facilitating functional recovery from TBI and are worth further investigation.

		                        			Mounting evidence has shown that exercise exerts extensive beneficial effects, including preventing and protecting against chronic diseases, through improving metabolism and other mechanisms. Recent studies have shown that exercise preconditioning affords significant cardioprotective effects. However, whether exercise preconditioning improves high fat diet (HFD)-induced obesity and lipid metabolic disorder remains unknown. The study was aimed to explore the effects of exercise preconditioning on HFD-induced obesity and lipid metabolic disorder in mice. 4-week-old C57BL/6 mice were subjected to swimming or sedentary control for 3 months, and then were fed with normal diet (ND) or HFD for 4 more months. The results showed that the blood glucose was decreased, and the glucose tolerance and grip strength were increased in exercised mice after training. Exercise preconditioning failed to improve HFD-induced body weight gain, but improved HFD-induced glucose intolerance. Exercise preconditioning showed no significant effects on both exercise capacity and physical activity in ND- and HFD-fed mice. HFD feeding increased total cholesterol and low density lipoprotein (LDL) levels in circulation, promoted subcutaneous fat and epididymal fat accumulation in mice. Exercise preconditioning increased circulating high density lipoprotein (HDL) and decreased circulating LDL, without affecting the subcutaneous fat and epididymal fat in HFD-fed mice. HFD feeding increased liver weight and hepatic total cholesterol contents, and dysregulated the expressions of several mitochondria function-related proteins in mice. These abnormalities were partially reversed by exercise preconditioning. Together, these results suggest that exercise preconditioning can partially reverse the HFD-induced lipid metabolic disorder and hepatic dysfunction, and these beneficial effects of exercise sustain for a period of time, even after exercise is discontinued.

		                        			Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ2=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

		                        			Objective: To analyze the follow-up and clinical effect of multidisciplinary treatment on the children with spinal muscular atrophy (SMA). Methods: The clinical data including nutritional status, respiratory function, bone health and motor function of 45 children with SMA who received multidisciplinary management 1-year follow-up in the Children's Hospital, Zhejiang University School of Medicine from July 2019 to October 2021 were retrospectively collected. Comparisons before and after management were performed using paired-samples t-test or Wilcoxon rank-sum test, etc. Results: The age of 45 patients (25 boys and 20 girls) was 50.4 (33.6, 84.0) months at the enrollment, with 6 cases of type 1, 22 cases of type 2, and 17 cases of type 3 respectively. After the multidisciplinary management, the cases of SMA patients with malnutrition decreased from 22 to 12 (P=0.030), the level of vitamin D were significantly increased ((45±17) vs. (48±14) nmol/L, t=-4.13, P<0.001). There was no significant difference in the forced vital capacity %pred, the forced expiratory volume at 1 second %pred, and the peak expiratory flow %pred ((76±19)% and (76±21)%, (81±18)% and (79±18)%, (81±21)% and (78±17)%; t=-0.24, 1.36, 1.21; all P>0.05). The Cobbs angle of scoliosis also improved significantly (8.0°(0°, 13.0°) vs. 10.0°(0°, 18.5°), Z=-3.01, P=0.003). The Hammersmith functional motor scale expanded scores of children with SMA type 2 and type 3 both showed significant elevation (11.0 (8.0, 18.0) vs. 11.0 (5.0, 18.5) scores, 44.0 (36.5, 53.0) vs. 44.0 (34.0, 51.5) scores, Z=2.44, 3.11, P=0.015, 0.002). Conclusion: Multidisciplinary management is beneficial for delaying the progression of the multi-system impairments of SMA patients, such as malnutrition, restrictive ventilation dysfunction and scoliosis.

		                        			OBJECTIVE:
		                        			To choose the disease-causing gene in a Chinese pedigree with ankylosing spondylitis (AS) by whole-exome sequencing (WES), and provide theory basis for mechanism of disease.
		                        		
		                        			METHODS:
		                        			Clinical data of AS pedigree were collected, including 2 males, the age were 48 and 18 years old, the course of disease were 23 and 4 years. Whole blood genomic DNA of AS was extracted to perform whole exome sequencing, the results were compared with human databases, common variations which had been reported were wiped out, then non synonymous single nucleotide variants(SNVs) from the family members were combined, and candidate genes was selected initially.
		                        		
		                        			RESULTS:
		                        			Totally 80 G data was obtained from AS family with high quality.By comparing results between patient and normal subject, and filtering with number of biological database, the result showed heterozygous mutation of JAK2 gene 12 exon c.1709 A>G (p.Tyr570Cys) may be the potential disease-causing gene. The variant c.1151T>C of MUC3A gene may be one of the causes of intestinal symptoms in the family members.
		                        		
		                        			CONCLUSION
		                        			It is feasible to find t candidate gene mutations of AS by Exon sequencing. The mutation c.1709 A>G in gene JAK2 identified by whole exome sequencing might be the pathogenic mutation in this AS pedigree.

		                        			OBJECTIVE:
		                        			Identification of new risk factors is needed to improve prediction of adverse outcomes in patients with three-vessel disease (TVD). The present study aimed to evaluate the prognostic values of serum chloride and sodium levels in patients with TVD.
		                        		
		                        			METHODS:
		                        			We used data from a prospective cohort of consecutive patients with angiographically confirmed TVD. The primary endpoint was all-cause death. Cox proportional hazard regression was used to analyze the relationship of serum chloride and sodium levels with long-term outcomes of TVD patients.
		                        		
		                        			RESULTS:
		                        			A total of 8,318 participants with available serum chloride and sodium data were included in this analysis. At baseline, patients in the low tertiles group of serum chloride level (⪕ 102.0 mmol/L) or serum sodium level (⪕ 139.0 mmol/L) had more severe disease conditions. During a median follow-up of 7.5-year, both low serum chloride level and low serum sodium level were found to be associated with an increased risk for mortality in univariate analysis. However, when both parameters were incorporated into a multivariate model, only low serum sodium level remained to be an independent predictor of all-cause death (hazard ratio: 1.16, 95% confidence interval: 1.01-1.34, P = 0.041). Modest but significant improvement of discrimination was observed after incorporating serum sodium level into the Synergy between percutaneous coronary intervention (PCI) with Taxus and Cardiac Surgery score.
		                        		
		                        			CONCLUSION
		                        			Serum sodium level is more strongly associated with long-term outcomes of TVD patients compared with serum chloride level. Low serum sodium level is an independent risk factor for mortality, but only provides modest prognostic information beyond an established risk model.

		                        			Objective:To analyze the prognostic factors for survival in elderly patients with glioma.Methods:We performed a retrospective analysis of prognostic factors for elderly patients with glioma,who were treated by the same attending doctor during June 2014 and June 2016,to investigate the correlations of the age,dimension of pathology,histological grade,extent of resection,adjuvant therapy,preoperative Karnofsky Performance Scale (KPS) score,postoperative KPS score,molecular markers [isocitrate dehydrogenase-1 (IDHH-1),O6-methylguanine DNA-transferase (MGMT),epidermal growth factor receptor (EGFR),Ki-67] with the prognosis.Results:A total of 45 patients were included in the study.The median overall survival (OS) was 11 months.The median progression-free survival (PFS) was 6 months.Univariate analysis revealed that the age,gender,dimension ofpathology,histological grade and preoperative KPS score had no significant correlation with survival (P>0.05).The gross total resection,higher postoperative KPS score,adjuvant therapy,lower Ki-67 index were significantly correlated with survival.The expressions of MGMT and EGFR were significant factors for survival.High postoperative KPS score (P=0.019),adjuvant therapy (P=0.024),and the expression of MGMT (P=0.026) were independent predictors for increased median OS in a multivariate regression model.Conclusion:The extent of resection,adjuvant therapy,postoperative KPS score and molecular markers are the influential factors for survival.Larger prospective studies are needed to confirm these findings.

		                        			Objectives:The purpose of this study was to explore the relationship between the of pericardial adipose tissue (PAT) volume and cardiovascular disease risk factors and energy consumption. Methods:From September 2014 to December 2015,we enrolled 152 inpatients underwent coronary artery CT examination due to suspected coronary heart disease in the Hospital on Integration of Chinese and Western Medicine Affiliated to Nanjing University of Chinese Medicine.The volume of PAT was assessment by 64-slice CT, the energy consumption was assessment by the International Physical Activity Questionnaire. The clinical data, biochemical indexes, PAT volume were analyzed. Results : (1) PAT volume was significantly correlated with age, gender, BMI, HOMA-IR, FPG, HDL-C, TG, total physical activity energy consumption, total middle intensity physical activity energy consumption, total energy consumption of sedentary (P<0.05 or P<0.001); (2) PAT volume of patients with insulin resistance was significantly higher than those without insulin resistance; (3) Multiple regression analysis revealed that age, gender, BMI, total middle intensity physical activity energy consumption were independent predictors of PAT volume. Conclusions: Pericardial adipose tissue (PAT) volume is associated with age, gender, systolic blood pressure, BMI, total middle intensity physical activity energy consumption.

OBJECTIVETo analyze a child with facial abnormalities with combined cytogenetic and molecular techniques and delineate its clinical phenotype.
METHODSNeuropsychological profile of the child was analyzed. Color Doppler, CT and MRI were used for detecting the nodules in the body. Conventional peripheral blood karyotypes of the child and his parents were analyzed with G-banding. Array-comparative genomic hybridization (aCGH) was performed to detect minor structural chromosomal abnormalities.
RESULTSThe child had mental retardation, maxillofacial dysmorphism on the right side, and irregular solid nodules on the back. The karyotypes of the child and his parents were all normal, while aCGH has identified a de novo constitutive 1.2 Mb deletion at 17q11.2 in the child. The aCGH results of his parents were normal.
CONCLUSIONThe de novo 17q11.2 microdeletion probably underlies the facial abnormalities and neurofibromatosis in the patient.
