ABSTRACT
Objective To provide guidance for pre-hospital emergency treatment by studying the disease spectrum and distribution characteristics of pre-hospital emergency treatment patients in Wuxi area from 2015 to 2020. Methods The medical records of 120 pre-hospital emergency patients in Wuxi area from January 2015 to December 2020 were retrospectively analyzed, and the disease types, gender, age, and seasonal distribution of the pre-hospital emergency patients were statistically analyzed. Results The top five emergency diseases of 16 437 pre-hospital patients were trauma (24.51%), cerebrovascular disease (19.16%), cardiovascular disease (18.33%), digestive system disease (9.70%) and respiratory disease (7.20%). In the distribution of disease types, the proportions of injuries, cerebrovascular diseases, cardiovascular diseases, digestive system diseases, respiratory system diseases, poisoning diseases and urinary system diseases in males were significantly higher than those in females (χ2=4.975, P<0.05). The proportion of male species (9 812/16 437) was higher than that of female species (6 625/16 437). From 2015 to 2020, the age group with high incidence of pre-hospital emergency patients in Wuxi area was distributed in the 50-60 years old (19.30%) and 40-50 years old (16.28%), and the least age group was 0-10 years old (2.60%). The number of pre-hospital emergency patients was 46.60% from 6 to 12 hours per day, and 10.26% from 18 to 24 hours per day. The number of pre-hospital emergency patients was the highest in summer (38.69%), and the lowest in spring (11.87%). Conclusion The pre-hospital emergency diseases in Wuxi area are mainly cardiovascular and cerebrovascular diseases, and the acute and severe diseases show an increasing trend. It is necessary to rationally allocate the pre-hospital emergency resources according to the disease spectrum and the peak months and time periods of different diseases, so as to improve the medical service level in Wuxi.
ABSTRACT
<p><b>OBJECTIVE</b>To assess the association of short tandem repeats (STRs) loci with aggressive behaviors of schizophrenia.</p><p><b>METHODS</b>Blood samples from 123 schizophrenic patients with aggressive behaviors and 489 schizophrenic patients without aggressive behaviors were collected. DNA from all samples was amplified with a PowerPlex 21 system and separated by electrophoresis to determine the genotypes and allelic frequencies of 20 STR loci including D3S1368, D1S1656, D6S1043, D13S317, Penta E, D16S639, D18S51, D2S1338, CSF1PO, Penta D, TH01, vWA, D21S11, D7S820, D5S818, TPOX, D8S1179, D12S391, D19S433, and FGA.</p><p><b>RESULTS</b>All of the 20 STR loci have reached Hardy-Weinberg equilibrium in both groups. A significant difference was found in allelic and genotypic frequencies of loci Penta D between the two groups (alleles: P=0.042; genotypes: P=0.014) but not for the remaining 19 loci (P> 0.05). Univariate analysis also showed a significant difference for allele 10 and genotypes 10-12 of Penta D between the two groups (P=0.0027, P=0.0001), with the OR being 1.81 (95%CI: 1.22-2.67) and 4.33 (95%CI: 1.95-9.59), respectively.</p><p><b>CONCLUSION</b>Penta D may be associated with aggressive behaviors of schizophrenia. Allele 10 and genotypes 10-12 of Penta D may confer a risk for the disease.</p>

Objective: To study the effect of lipopolysaccharides(LPS) on nitric oxide(NO) production in synoviocytes and inhibition of genistein on it.Methods: LPS or LPS+genistein stimulated synoviocytes in vitro .NO in culture medium was determined by Griess method.Results: LPS dose and time dependently induced NO production in synoviocytes; Genistein (6.25 50 ?mol/L) dose dependently inhibited the production of NO induced by lipopolysaccharide.Conclusion:The effect of LPS on NO production can be dose dependently inhibited by genistein,this may be mediated by tyrosine kinase(PTK).
ABSTRACT
Objective To study indole alkaloids of Ervatamia hainanensis. Methods The compounds were separated and purified by column chromatography with silica gel and Sephadex LH-20. The structures were identified by IR, MS, and NMR. Results Seven alkaloids were identified as: hainanervatasine (Ⅰ), hainanervatacine (Ⅱ), vobasine (Ⅲ), coronaridine (Ⅳ), 3-hydroxyl coronaridine (Ⅴ), 3-(2-oxopropyl) coronaridine (Ⅵ), and tabernamine (Ⅶ), respectively. Conclusion Compounds Ⅰ and Ⅱ are new compounds. Compounds Ⅳ and Ⅵ are isolated from this plant for the first time.
ABSTRACT
Objective To study the triterpenoids from the canes with leaves of Trachelospermum jasminoides.Methods The compounds were separated and purified by column chromatography with silica gel,RP-C_(18),Sephadex LH-20 and identified by IR,MS,NMR,and 2D-NMR.Results Eight triterpenoids were identified as: trachelosperoside F(Ⅰ),trachelosperoside B-1(Ⅱ),trachelosperoside D-1(Ⅲ),trachelosperoside E-1(Ⅳ),3?-O-D-glucopyranoside quinovic acid(Ⅴ),3?-O-?-D-glucopyranoisde quinovic acid 27-O-?-D-glucopyranosyl ester(Ⅵ),3?-O-?-D-glucopyranoside cincholic acid 27-O-?-D-glucopyranosyl ester(Ⅶ),trachelosperogenin B(Ⅷ),respectively.Conclusion Compound Ⅰ is a new compound and compounds Ⅱ-Ⅷ are isolated from this plant for the first time.
