Depression,a common mood disorder,has a complex pathogenesis.In recent years,the accelerated pace of life has been accompanied by an increase in the prevalence rate of depression,leading to extensive attention being given to this condition.External stress and inflammation synergize to damage blood vessel and brain functions,induce immune disorders,cause microglia activation,and increase the expression of pro-inflammatory cytokines and their receptors.Inflammatory reactions continue to escalate,which affects the normal metabolism and metabolism of the neurotransmitter system.The abnormal functioning of molecular pathways leads to mutations in brain cell and nerve genes,and further formation of the immune-inflammation-neuron cycle pathway becomes an important mechanism in the occurrence and development of depression.A large number of studies have shown that traditional Chinese medicines can improve depression symptoms by restoring neuroimmune inflammation homeostasis.This article explains neuroimmune inflammation's close connection with depression and its pathogenesis and reviews the role of various traditional Chinese medical therapies in improving and treating depression by participating in the regulation of neuroimmune inflammation.This review provides new perspectives on the precise treatment of depression and the development of immune-targeted drugs.

BACKGROUND:
China bears the biggest atrial fibrillation (AF) burden in the world. However, little is known about the incidence and predictors of AF. This study aimed to investigate the current incidence of AF and its electrocardiographic (ECG) predictors in general community individuals aged over 60 years in China.
METHODS:
This was a prospective cohort study, recruiting subjects who were aged over 60 years and underwent annual health checkups from April to July 2015 in four community health centers in Songjiang District, Shanghai, China. The subjects were then followed up from 2015 to 2019 annually. Data on sociodemographic characteristics, medical history, and the resting 12-lead ECG were collected. Kaplan-Meier curve was used for showing the trends in AF incidence and calculating the predictors of AF. Associations of ECG abnormalities and AF incidence were examined using Cox proportional hazard models.
RESULTS:
This study recruited 18,738 subjects, and 351 (1.87%) developed AF. The overall incidence rate of AF was 5.2/1000 person-years during an observation period of 67,704 person-years. Multivariable Cox regression analysis indicated age (hazard ratio [HR], 1.07; 95% confidence interval [CI]: 1.06-1.09; P < 0.001), male (HR, 1.30; 95% CI: 1.05-1.62; P = 0.018), a history of hypertension (HR, 1.55; 95% CI: 1.23-1.95; P < 0.001), a history of cardiac diseases (HR, 3.23; 95% CI: 2.34-4.45; P < 0.001), atrial premature complex (APC) (HR, 2.82; 95% CI: 2.17-3.68; P < 0.001), atrial flutter (HR, 18.68; 95% CI: 7.37-47.31; P < 0.001), junctional premature complex (JPC) (HR, 3.57; 95% CI: 1.59-8.02; P = 0.002), junctional rhythm (HR, 18.24; 95% CI: 5.83-57.07; P < 0.001), ventricular premature complex (VPC) (HR, 1.76; 95% CI: 1.13-2.75, P = 0.012), short PR interval (HR, 5.49; 95% CI: 1.36-22.19; P = 0.017), right atrial enlargement (HR, 6.22; 95% CI: 1.54-25.14; P = 0.010), and pacing rhythm (HR, 3.99; 95% CI: 1.57-10.14; P = 0.004) were independently associated with the incidence of AF.
CONCLUSIONS
The present incidence of AF was 5.2/1000 person-years in the studied population aged over 60 years in China. Among various ECG abnormalities, only APC, atrial flutter, JPC, junctional rhythm, short PR interval, VPC, right atrial enlargement, and pacing rhythm were independently associated with AF incidence.

Objective:
To examine the effects of obesity and central obesity on hypertension, so as to provide insights into the prevention and control measures of hypertension.
Methods:
From September to December 2018, residents at ages of 35 to 75 years were sampled using the multi-stage random sampling method in Baiyin District, Baiyin City, Gansu Province, and subjected to questionnaire surveys and physical examinations. The interaction between obesity/central obesity and hypertension was evaluated using logistic regression analysis. The synergy index ( SI ), relative excess risk due to interaction ( RERI ) and attributable proportion due to interaction ( AP ) were calculated using Excel compiled by Andersson et al.
Results:
A total of 6 246 questionnaires were allocated and 6 169 valid questionnaires were recovered, with an effective recovery rate of 98.77%. The respondents included 3 038 men ( 49.25% ) and 3 131 women (50.75%), with a mean age of ( 52.05±8.78 ) years. There were 832 respondents with obesity ( 13.49% ) and 2 278 with central obesity ( 36.93% ). The crude and standardized prevalence rates of hypertension were 35.89% and 33.05%, respectively. Multivariable logistic regression analysis showed that obesity ( OR=2.020, 95%CI: 1.705-2.393 ) and central obesity ( OR=1.622, 95%CI: 1.433-1.836 ) were statistically associated with hypertension. There was no multiplicative interaction between obesity or central obesity and hypertension ( OR=1.011, 95%CI: 0.655-1.560 ), and no additive interaction was detected between obesity or central obesityand hypertension ( SI=1.405, 95%CI: 0.815-2.424; RERI=0.658, 95%CI: -0.298 to 1.614; AP=0.201, 95%CI: -0.075 to 0.476 ).
Conclusions
Obesity and central obesity increase the risk of hypertension; however, no interaction is detected between obesity or central obesity and hypertension.

Objective:To investigate the drug resistance and pathogenic mechanism of a uropathogenic Escherichia coli (UPEC) strain UPEC132 at the genome-wide level. Methods:The susceptibility of UPEC132 strain to 16 antimicrobial agents was determined by minimum inhibitory concentration (MIC) assay. The UPEC132 strain was genotyped by multilocus sequence typing (MLST). The three-generation sequencing platform was used to sequence and assemble the whole genome of the UPEC132 strain. Drug resistance and virulence gene function annotations were predicted by Prodigal software and screened by using genome database. Genome sequences of the UPEC132 strain and 23 other UPEC strains collected from GenBank were phylogenetically analyzed, and a phylogenetic tree was constructed by RAxML software.Results:The UPEC132 strain was resistant to ampicillin, ampicillin/sulbactam, tetracycline, erythromycin, chloramphenicol and cefazolin. Its genotype was ST10522 by MLST. The whole genome of the UPEC132 strain included one complete genome (chromosome) and two plasmid sequences. The sequence sizes of the chromosome and plasmids 1 and 2 were 5 234 468 bp, 117 139 bp and 101 356 bp, and the guanine-cytosine (GC) content was 50.48%, 49.05%, and 54.04%, respectively. There were 4 856, 140 and 116 genes annotated in the chromosome and plasmids 1 and 2, respectively. Drug resistance genes were mainly distributed in the chromosomal genome, mainly including the multidrug resistance efflux pump gene clusters. Only blaTEM-1 and tetG genes were carried in the plasmid 2. Virulence genes were also mainly distributed in the chromosome genome, including nine pilus adhesins, five iron uptake systems and three secretory toxins. Gene clusters encoding Afa and type Ⅳ fimbriae were located on plasmids 1 and 2, respectively. The phylogenetic tree showed that the UPEC132 strain was not in the same branch with either of the 23 UPEC strains. Conclusions:The UPEC132 strain belonged to ST10522, which was a newly named ST type of Escherichia coli and first reported at home and abroad. The genome-wide genetic information of the UPEC132 strain was fully revealed. The multidrug resistance genes and virulence genes carried by the UPEC132 strain were associated with its drug resistance and pathogenicity.

Objective To explore the effect of leptin on neurorehabilitation and on the expression of dopamine receptor D2 (Drd2) and cytosolic phospholipase A2 (cPLA2) in the cerebral cortex after convulsive brain injury.Methods Five-day-old Sprague-Dawley rats were randomly assigned to a control group (CONT),a leptin injection control group (Leptin),a seizure group (RS),or a seizure with leptin injection group (RS+Leptin).The rats in the RS group and the RS+Leptin group were injected intraperitoneally with lithium chloride (5 mEq/kg) and pilocarpine (320 mg/kg) on day 6,and then scopolamine methyl chloride (1 mg/kg) 30 minutes later to block the peripheral effect of pilocarpine.The animals in the Leptin and RS+Leptin groups were then given leptin (4 mg/kg,i.p.) injections daily from days 8 to 14.The animals' plane righting reflex and negative geotaxis reaction reflex were observed on day 23.The open field test was performed on D30.Real-time reverse-transcription polymerase chain reactions (RT-PCRs) were used to detect the expression of Drd2 and cPLA2 mRNA in the rats' cerebral cortexes on day 34.Results There were significant differences in the plane righting times and negative geotaxis reflexes among the four groups,with those in the RS and RS+Leptin groups significantly longer than among the controls.Both reflexes were significantly quicker in the RS + Leptin group than in the RS group.There were also significant differences in the locomotor scores in the open field test among the four groups,with the average scores in the RS and RS+Leptin groups significantly higher than in the other two groups.The RS+Leptin group's average was significantly higher than that of the RS group.The expression of Drd2 was significantly higher in the leptin,RS and leptin +RS groups than in the control group,and that of the RS and leptin+RS groups was significantly higher than that of the Leptin control group.The expression of cPLA2 in the Leptin and RS groups was significantly higher than in the CONT group,while that of the RS + Leptin group was significantly lower than in the Leptin and RS groups.Conclusions Leptin has a neurorehabilitation effect on the behavioral impairment caused by seizures,at least in neonatal rats.Its neuroprotective mechanism may be related to the regulation of Drd2-mediated cPLA2 expression in the cerebral cortex.
