Objective To explore the relationship between quality life and TCM constitutions of elderly patients with hypertension in a community in Shanghai; To provide the basis for the suitable and feasible community elderly hypertension management method. Methods Through multistage stratified sampling method, 808 elderly patients with hypertension in the community were investigated for their life quality and TCM constitutions on the basis of inform consent and voluntary participation. The life quality and TCM constitution characteristics as well as the relationship were analyzed by applying the statistic analysis software. Results Among the investigated elderly patients with hypertension in the community, 97.28% cases’ overall life quality was above the middle level and 91.46% cases’ self-evaluated health and quality of life scores were above the middle level. 54.70% cases were gentleness type, and the biased constitution was dominated by qi deficiency, yang asthenia, yin asthenia and phlegmatic hygrosis. The relationship between life quality and TCM constitutions may be existent. If TCM constitutions tended to be gentleness type, the physical score and the psychological score would be higher, which leaded to better quality of life. Conclusion TCM constitution characteristics are associated with quality life of elderly hypertension patients in the community. Intervention targeted on the results of TCM constitution identification would be better to prevent and control hypertension and improve health level and quality of life.

BACKGROUND: Apolipoprotein(a) [Apo(a)] plays some role in promoting the formation of atherosclerotic plaque, and contains pentanucleotide repeats(PNR), which has a key value in genic research and in forecast on the increased risk of early atherosclerosis cerebral infarction (ACI). But the relationship between ACI and Apo(a) PNR in different races needs to be further investigated.OBJECTIVE: To investigate the relationship between the Apo(a) PNR polymorphism and ACI.DESIGN: A case-control study based on the ACI patients and normal people of Han nationality in Hubei.SETTING: Department of Laboratory in a hospital of a university.PARTICIPANTS: From February 1998 to March 1999, 82 ACI patients (ACI group) and 153 healthy controls(control group) were selected from the Department of Neurology, Central South Hospital and Yatai Hospital of Wuhan University. All patients were Han nationality in Hubei without any relatives.METHODS: Serum lipoprotein(a) [Lp(a) ], total cholesterol(TC), high density lipoprotein cholesterol(HDL-c), low density lipoprotein cholesterol (LDL-c), triglyceride (TG), apolipoprotein A Ⅰ (ApoA Ⅰ) and apolipoprotein B (Apo B) were tested respectively. Meanwhile, the PNR in the 5' control region of the Apo(a) was detected with polymerase chain reaction(PCR) and high voltage polyacrylamide gels electrophoresis. The results were analyzed with controlled analysis.RESULTS: The levels of serum Lp(a) [ (239.9 ±225.4) mg/L], TC [(4.76±0.74) nmol/L], TG[(1.74±0.60) mmol/L] and LDL-C [ (2.84 ± 0. 63) mmol/L] were remarkably higher in ACI group than those in control group, which were(133.5 ±97.7) mg/L in serum Lp(a), (4. 29±0.72) mmol/L in TC, (1.05±0.52) mmol/L in TG and(2.84±0.63) mmol/L in LDL-C, however, the level of HDL-C[ (0.88± 0.17) mmol/L] was remarkably lower in ACI group than that in control group [ ( 1.03 ± 0. 35 ) mmol/L], the differences were all significant( t = 3.65to9.18, P ＜ 0.01) . The levels of ApoA Ⅰ [(1.13±0.15) mmol/L,(1.25±0.19) mmol/L] and ApoB[(0.93±0.12) mmol/L, (0.89± 0. 15 ) mmol/L] were no significant difference compared with those in control group. The duplicated frequency of the allele(TTTTA) 5(0. 098) in the ACI was remarkably higher than that in control(0. 026) (x2 = 5.62, P＜ 0. 05), The frequency of the allele(TTTTA) 9 in the ACI(0. 073) was remarkably lower than that in control (0. 213 ) (x2 = 7.83, P ＜ 0.01 ), The frequency of the allele(TTTTA) 5 was also associated with low TC and high Lp(a) levels.CONCLUSION: It is suggested that the Apo(a) PNR polymorphism are associated with the susceptibility to ACI, and involved in the development of ACI.

Objective: To study the anti-gout effect of active ingredients in Poecilobdella manillensis. Methods: Hypoxanthine was used to replicate mouse model of hyperuricemia, and xylene was used to induce mouse auricle swelling model. The hot plate method and writhing method were used to screen the active site of Poecilobdella manillensis, and then the active ingredients were screened. The material basis of anti-gout effect of Poecilobdella manillensis was observed. Results: The water-soluble fraction of Poecilobdella manillensis was the active site against gout, which could reduce the level of serum uric acid in hypoxanthine-induced hyperuricemic mice and inhibit xylene-induced auricular swelling in mice, deduce acetic acid-induced writhing reaction in mice and increase the hot plate pain threshold in mice; Hirudin was the main active ingredient in water-soluble parts. Poecilobdella manillensis active ingredient 0.8 g/kg and 0.4 g/kg and Poecilobdella manillensis residue 2.0 g/kg could significantly reduce serum uric acid levels. The serum uric acid levels decreased from232.73 ± 50.93 umol/L in model group to 140.70 ± 25.97 umol/L, 149.07 ± 39.28 umol/L, 176.45 ± 44.33 umol/L, respectively (P ＜ 0.01) . Poecilobdella manillensis active ingredients 0.8 g/kg, 0.4 g/kg and 0.2 g/kg and Poecilobdella manillensis residue 2.0 g/kg could significantly inhibit xylene-induced ear auricle swelling in mice. The swelling degree was inhibited from 22.80 ± 2.86 mg to 20.10 ± 2.18 mg, 19.80 ± 2.57 mg, 20.10 ± 1.66 mg and 20.85 ± 1.60 mg respectively (P ＜ 0.05) . Poecilobdella manillensis 0.8 g/kg active ingredient could significantly reduce the number of writhing mice caused by acetic acid. The number of times was reduced from 22.80 ± 2.86 times to 20.10 ± 2.18 times (P ＜0.05) . Conclusion: Poecilobdella manillensis anti-gout activity is in water-soluble parts, and Hirudin is the main active ingredient.

Objective: To understand the homology and resistance characteristics of Streptococcus pneumoniae (S. pneumoniae) in healthy preschool children, so as to provide basis for disease transmission prevention and rational use of antibiotics. Methods: Stratified cluster random sampling method was used to sample 1 829 healthy children from six kindergartens in Shunde District, Foshan City. Nasal swabs were taken and tested for S. pneumoniae. Multi locus sequence typing was used for homology analysis. The Chi squared test and random forest analysis were used to explore the resistance characteristics. Results: The nasal carriage rate of S. pneumoniae and multidrug resistant S. pneumoniae (MDRSP) in children were 22.5%(412/1 829) and 21.3%(390/1 829), respectively. Homology analysis in sequence types showed that the total homology rates of 6 kindergartens were 93.5%(87/93), 91.1% (72/79), 89.2%(58/65), 88.9%(64/72), 86.2%(50/58), 77.8%(35/45), respectively. It was found that the highest homology rate was 82.8% (48/58) within class and 93.1% (81/87) between classes. S. pneumoniae was mainly resistant to azithromycin (97.1%, 400/412), erythromycin (92.0%, 379/412) and tetracycline (91.5%, 377/412). The dominant multidrug resistance pattern of MDRSP isolates was not sensitive to azithromycin, erythromycin, cotrimoxazole, tetracycline and clindamycin. Random forest analysis indicated that the important phenotypic markers associated with MDRSP were resistance to azithromycin, cotrimoxazole, tetracycline, clindamycin and erythromycin(MDG=8.94, 6.92, 5.80, 4.84, 2.58). Conclusion The risk of cross transmission of S. pneumoniae among preschool children is high, and direct contact is the main way of transmission. Consequently, kindergartens and health departments should take effective measures to effectively prevent and block the spread of Streptococcus pneumoniae.

Objective:To understand the quality of life of high risk population of stroke in community and analyze the influencing factors.Methods:Four community health service centers in Huangpu District were randomly selected, and the subjects were included by using convenient sampling method among the high risk groups of stroke found in the community stroke screening and prevention and control project in Shanghai.The World Health Organization quality of life scale-brief form questionnaire(WHOQOL-BREF), self-rating depression scale (SDS) and self-rating anxiety scale (SAS) were used as the survey tools to study 1200 high-risk stroke subjects.Single sample t-test was used to compare the differences between the scores and the data of 24 centers in the world, and multiple linear stepwise regression were used to analyze the influencing factors. Results:The scores of physical field, psychological field and social relationship field ((13.60±1.86), (14.58±1.97), (13.72±2.10)respectively) of high-risk population of stroke were lower than the scores of general population of 24 centers in the world ( P<0.01), and the scores of environmental field (14.08±1.95) were higher than it ( P<0.01), of which the differences were all statistically significant.The results of multiple linear stepwise regression analysis showed that old age, anxiety and depression were the risk factors influencing the scores of physical field( β=-0.027, -0.056, -0.051), psychological field( β=-0.019, -0.055, -0.050) and environmental field( β=-0.017, -0.040, -0.054); old age and depression were the risk factors influencing the scores of social relationship field( β=-0.026, -0.067); anxiety and depression were the risk factors influencing the self-assessment of quality of life and health ( β=-0.012, -0.014 for quality of life; -0.012, -0.014 for health, all P<0.01). Conclusion:The quality of life of high-risk population of stroke may be related to age, depression, anxiety and other psychological factors.The prevention and treatment of stroke should take both physical and mental measures, take timely intervention for poor psychological status, and gradually improve the quality of life.

Marine fungi are important members of the marine microbiome, which have been paid growing attention by scientists in recent years. The secondary metabolites of marine fungi have been reported to contain rich and diverse compounds with novel structures (Chen et al., 2019). Aspergillus terreus, the higher level marine fungus of the Aspergillus genus (family of Trichocomaceae, order of Eurotiales, class of Eurotiomycetes, phylum of Ascomycota), is widely distributed in both sea and land. In our previous study, the coral-derived A. terreus strain C23-3 exhibited potential in producing other biologically active (with antioxidant, acetylcholinesterase inhibition, and anti-inflammatory activity) compounds like arylbutyrolactones, territrems, and isoflavones, and high sensitivity to the chemical regulation of secondary metabolism (Yang et al., 2019, 2020; Nie et al., 2020; Ma et al., 2021). Moreover, we have isolated two different benzaldehydes, including a benzaldehyde with a novel structure, from A. terreus C23-3 which was derived from Pectinia paeonia of Xuwen, Zhanjiang City, Guangdong Province, China.

The objective was to investigate the effect of kinsenoside (Kin) treatments on macrophage polarity and evaluate the resulting protection of chondrocytes to attenuate osteoarthritis (OA) progression. RAW264.7 macrophages were polarized to M1/M2 subtypes then administered with different concentrations of Kin. The polarization transitions were evaluated with quantitative real-time polymerase chain reaction (qRT-PCR), confocal observation and flow cytometry analysis. The mechanism of Kin repolarizing M1 macrophages was evaluated by Western blot. Further, macrophage conditioned medium (CM) and IL-1 were administered to chondrocytes. Micro-CT scanning and histological observations were conducted on anterior cruciate ligament transection (ACLT) mice with or without Kin treatment. We found that Kin repolarized M1 macrophages to the M2 phenotype. Mechanistically, Kin inhibited the phosphorylation of IB, which further reduced the downstream phosphorylation of P65 in nuclear factor-B (NF-B) signaling. Moreover, Kin inhibited mitogen-activated protein kinases (MAPK) signaling molecules p-JNK, p-ERK and p-P38. Additionally, Kin attenuated macrophage CM and IL-1-induced chondrocyte damage. , Kin reduced the infiltration of M1 macrophages, promoted M2 macrophages in the synovium, inhibited subchondral bone destruction and reduced articular cartilage damage induced by ACLT. All the results indicated that Kin is an effective therapeutic candidate for OA treatment.
