ABSTRACT
Objective To analyze the epidemiological characteristics of automatic warning signals of infectious diseases received in Tianjin during the 13th Five-Year Plan period, and to provide reference for the function optimization of automatic warning system of infectious diseases during the 14th Five-year Plan period. Methods The data of infectious disease automatic early warning signals in Tianjin from 2016 to 2020 were downloaded from the China infectious diseases automated-alert and response system (CIDARS). The characteristics and response of early warning signals were analyzed by descriptive method. Results During the 13th Five-Year Plan period, 23,660 early warning signals were received in Tianjin, involving 39 kinds of infectious diseases, with 100% response rate and 1.10% positive rate of early warning signals. The median response time of warning signal was 0.53 hours (P25-P75: 0.19-1.17h). 95.74% of signals were responded within 2 hours and 98.47% of signals were responded within 24 hours. COVID-19, other infectious diarrhea diseases, dysentery, measles, and scarlet fever were the top five diseases with early warning signals. Conclusion During the 13th Five-Year, the automatic early warning system of infectious diseases in Tianjin runs well and has a high response rate, but the positive rate of early warning signal is low. During the 14th Five-Year,further research is needed to improve the early warning threshold according to the prevention and control needs and epidemic characteristics of different diseases, and to improve early warning positive rate.
ABSTRACT
Objective To explore the relationship among depression,anxiety and social support in elderly patients in community outpatient clinic. Methods A total of 551 elderly outpatients from two com-munity health service centers of Hongkou District in Shanghai were evaluated with patient health question-naire-9 (PHQ-9),generalized anxiety disorder-7 (GAD-7),perceived social support scale( PSSS) for de-pression,anxiety,physical health and social support. Results The prevalence rates of depression and anxiety were 26. 1% and 17. 2%,respectively. The scores of PHQ-9 and GAD-7 were 2. 0(4. 0) and 1. 0(2. 0). There were statistically significant differences in the scores of family support,friend support,other support and social support among the elderly patients with different degrees of depression or anxiety (P<0. 01). Fam-ily support(B=-0. 196) and friend support(B=-0. 171) were protective factors of depression in elderly pa-tients in community outpatient clinic. Age,family support and friend support were protective factors of anxiety in elderly patients,while gender and fluctuation of physical diseases were protective factors of anxiety(P<0. 05). Con-clusions The depression and anxiety is intimately related to social support in elderly outpatients. Appropriate measures should be taken to optimize social support,mitigate bad mood negative improve their quality of life.
ABSTRACT
Objective·To compare the clinical features between different subtype bipolar patients with first mania episode, and to contribute to early identification of bipolar disorder. Methods·This study was based on the database named as National Bipolar Mania Pathway Survey (BIPAS). From November 2012 to January 2013, bipolar patients from 26 mental health facilities in China were enrolled in current study. The clinical features were compared between mania patients of different subtypes, including hypomania (groupⅠ), mania without psychotic symptoms (groupⅡ), mania with psychotic symptoms (group Ⅲ) and mixed state (group Ⅳ). Results·There was significant difference in the percentage of clinical symptoms between different subtype bipolar patients with first mania episode, especially the mania and anxiety related symptoms. Group Ⅰ, Ⅲ , Ⅳ were further compared with groupⅡ, which was considered as the typical bipolar disorder. The results showed that the mania related symptoms was significantly higher in group Ⅱ, but anxiety related symptoms was significantly higher in group Ⅰ, Ⅲ, Ⅳ. Moreover, Logistic regression analysis revealed that more eloquent or humor and unusually restless could be in favor of the diagnosis of hypomania; younger and mania or hypomania as first episode might be in favor of the diagnosis of mania with psychotic symptoms; older, national minorities and unusually restless could be in favor of the diagnosis of mixed state. Conclusion·The clinical features between different subtype bipolar patients with first mania episode are various, and analysis of the clinical features can contribute to early identification of bipolar disorder.

ABSTRACT
OBJECTIVE: Evidence of the brain network involved in cognitive dysfunction has been inconsistent for major depressive disorder (MDD), especially during early stage of MDD. This study seeks to examine abnormal cognition connectivity network (CCN) in MDD within the whole brain. METHODS: Sixteen patients with MDD and 16 health controls were scanned during resting-state using 3.0 T functional magnetic resonance imaging (fMRI). All patients were first episode without any history of antidepressant treatment. Both the left and right dorsolateral prefrontal cortex (DLPFC) were used as individual seeds to identify CCN by the seed-target correlation analysis. Two sample t test was used to calculate between-group differences in CCN using fisher z-transformed correlation maps. RESULTS: The CCN was constructed by bilateral seed DLPFC in two groups separately. Depressed subjects exhibited significantly increased functional connectivity (FC) by left DLPFC in one cluster, overlapping middle frontal gyrus, BA7, BA43, precuneus, BA6, BA40, superior temporal gyrus, BA22, inferior parietal lobule, precentral gyrus, BA4 and cingulate gyrus in left cerebrum. Health controls did not show any cluster with significantly greater FC compared to depressed subjects in left DLPFC network. There was no significant difference of FC in right DLPFC network between depressed subjects and the health controls. CONCLUSION: There are differences in CCN during early stage of MDD, as identified by increased FCs among part of frontal gyrus, parietal cortex, cingulate cortex, and BA43, BA22, BA4 with left DLPFC. These brain areas might be involved in the underlying mechanisms of cognitive dysfunction in MDD.

ABSTRACT
Objective To investigate the relationship between cognitive function of first-episode schizophrenic patients and dopamine D1 receptor gene. Methods A total of 112 first-episode schizophrenic patients and 60 healthy controls were evaluated with Wechsler adult intelligence scale ( WAIS-R), Wechsler memory scale (WMS) and Wisconsin card sort test (WCST) ,and genotyped one polymorphism (rs4532) within DRD1 gene using TaqMan SNP genotyping assay. Results There were no significant differences on the frequencies of the genotypes and alleles of rs4532 polymorphism between patients with schizophrenia and normal controls ( x2 =2.90, P=0.35; x2 = 0.01, P= 0. 93 ). There were significant differences in all index of WCST between two groups (P <0.01 ). Patients with rs4532G allele had worse WCST performance than those without G allele ((60.9 ± 13.2)%vs (44.9 ±21.3)%, t=4.79, P=0.00002). Conclusion Rs4532 polymorphism of DRD1 gene may be associated with executive function impairment in schizophrenic patients.

ABSTRACT
Objective To investigate the time-dependent changes in glutamate (Glu) and 7-aminobutyric acid ( GABA) release in the rostral ventromedial medulla in a rat model of incisional pain. Methods Healthy male SD rats weighing 250-300 g were used in this study. Twelve rats in which microdialysis cannulae were implanted in the right rostral ventromedial medulla without neurological deficits were randomly divided into 2 groups ( n = 6 each): group A control and group B incisional pain. In group B an 1 cm long incision was made in the plantar surface of right hindpaw under 1.2% isoflurane anesthesia which was maintained for 5 min. Samples of dialysate were collected before incision (T_0 baseline) and at 3 h, 1 d, 2 d and 3 d after incision was made (T_(1-4)) in both groups for determination of Clu and GABA concentrations (by HPLC). Results In group B Glu and GABA concentrations in the dialysate were significantly increased at 1 d (T_2) and 3 h-3 d (T_(1-4)) respectively as compared with the baseline value at T_0 and were significantly higher than those in group A (control group). Conclusion Incisional pain increases the release of Glu and GABA in the rostral ventromedial medulla which might influence the function of descending pain modulation pathway.
ABSTRACT
OBJECTIVE@#To investigate the role of neuropeptide Y(NPY) positive interneurons in the generation and compensation of temporal lobe epilepsy.@*METHODS@#Pilocarpine-induced rat model was founded. Immunohistochemistry was used to observe the number changes and axonal sprouting of NPY interneurons at different time points in the hippocampus of rats.@*RESULTS@#After lithium-chloride and pilocarpine administration, 92.9% rats were induced status epilepticus (SE) successfully, and the mortality rate was 19.2%. In the experimental group, the number of NPY positive neurons decreased in the hilus of the hippocampus, and was least on 7 d after the SE (P0.05) except the loss of them in CA3 area on 7 d after the SE (P>0.05). Increased NPY positive fibers could be seen in the molecular layer of the dentate gyrus on 30 d after the SE.@*CONCLUSION@#NPY interneurons have different sensitivities to the injuries induced by seizures at different time points and domains. Loss of NPY interneurons plays an important role in the generation of temporal lobe epilepsy, while axonal sprouting of them may play a significant role in the compensation of temporal lobe epilepsy.

Objective To investigate the changes in the prescriptions of antidepressants for inpatients with psychosis from 2005 to 2008. Methods The prescriptions of antidepressants for all the inpatients with psychosis in Shanghai Mental Health Center were investigated by one day survey on each June 1st from 2005 to 2008. The most common diseases treated with antidepressants, the most commonly used antidepressants, the average dosage of antidepressants and the combination use of antidepressants were analysed. Results The most common diseases treated with antidepressants were affective disorder, schizophrenia and neurosis. The prescription rate of tricyclic antidepressants declined year by year, and that of selective serotonin reuptake inhibitors (SSRIs) fluctuated moderately, while that of antidepressants of newer generation with the other transmitter mechanisms such as venlafaxine, mitrazapine and trazodone increased gradually. Single antidepressant prescription was common, while the combination use of antidepressants accounted for a small portion. Combination use of antidepressants with one psychotropics (antipsychotics, mood stabilizer, sedative hypnotics) was common, while with two were less frequently occurred. Conclusion Prescriptions of antidepressants for patients with psychosis hospitalized in Shanghai Mental Health Center from 2005 to 2008 are relatively safe and reasonable. Antidepressants of newer generation have been widely used in clinics, and SSRIs have been serving as the major antidepressants.
ABSTRACT
Objective Linkage analysis were performed in 2 pure Chinese paroxysmal kinesigenic dyskinesia families to localize the locus of them. Method Microsatellites markers corresponding to pericentrometric region of chromosome 16 were used in parametric and nonparametrie linkage analysis for 27 members in the 2 pedigrees, haplotypes were constructed subsequently. Result The maximum LOD score and NPL score in the 2 families were all negative, P values were significantly larger than 0.05.No haplotype segregated with PKD phenotype was found. It showed no evidence of association with known PKD loci in both pedigrees, providing evidence for a novel PKD locus. Conclusion PKD is heterogeneous, a novel PKD locus may be in pure Chinese pedigrees.

ABSTRACT
AIM: G protein-coupled inwardly rectifier potassium (GIRK) channel are distributed widely in mammalian brain. In CNS, GIRK 1/2 seems to be the predominant heterotetramers which play a pivot role in the regulation of the excitability of neurons and may contribute to the resting potential by leading to a hyperpolarization of membrane potential and reduction of the action potential frequency. In the context, the Weaver mouse is the first neurological abnormality directly linked to a genetic point mutation in the GIRK2 protein which includes spontaneous seizure. GIRK2 knock out mice showed normal development but more susceptible than normal mice to seizure induced by GABA antagonist. Here, we report that the mRNA and protein expression of GIRK subunit 2 is altered in kainic acid(KA)-induced epileptic rat hippocampus. METHODS: Rats were injected with kainate 14 mg/kg intraperitoneally to establish an acute and chronic temporal lobe epilepsy model. At chronic spontaneous seizure stage, by using of in situ hybridization, immunocytochemistry and Western blotting, the GIRK 1,2 mRNA and protein were analyzed quantitatively in the dentate gyreus, CA1, CA3 regions of hippocampus. RESULTS: GIRK1,2 mRNA and proteins were expressed abundantly in all regions of hippocampus. KA induced seizures and caused a significant increase in GIRK2 mRNA abundance and immunoreacitivity; only GIRK1 mRNA was increased significantly, but no difference was found by Western blotting protocol. CONCLUSION: GIRK1,2 mRNA and protein expression in the hippocampus of epileptic rat brain is up-regulated, which may be an adaptive response to over-excitability of neuron networks and prevent the over-excitability spread in hippocampus (DG-CA3-CA1).
