Object To investigate the features of health related quality of life ( HRQOL) among elderly hypertensive patients with different body mass index (BMI) so s to provide evidence for the health promotion of hypertensive. Methods A cross-sectional survey of health status data from a population of 1281 elderly hypertensive patients from Beijing and 8 provinces of China ( Jiangsu, Anhui, Gansu, Qinghai, Fujian, Jilin, Jiangxi, and Henan) was made in the study. Analysis of variance was applied to compare the differences in HRQOL of elderly hypertensive patients in different BMI categories. Results For the elderly hypertensive patients with low body mass index, the scores of 8 dimensions and scores in physical component summary (PCS) and mental component summary( MCS) of SF-36 were the lowest;except the role-emotional(RE) dimension,the scores of other 7 dimensions,PCS and MCS were significantly different(PF,RP,BP,GH,VT,MH, P<0.01; SF,PCS,MCS, P<0.01). Comparing the scores between any two groups in PCS, the scores of patients with low body mass index were significantly lower than normal weight group (62.30 ± 22. 12 vs72.40 ±20.86, P<0.05) .overweight group (62.30 ± 22.12 vs 74.97 ± 19.20, P<0.05 ) and obese group (62.30 ± 22.12 vs 74.57 ± 19. 22, P < 0.05 ). Comparing the scores between any two groups in MCS,the scores of patients with low body mass index were significantly lower than normal weight group (68. 81 ± 20. 48 vs 74. 70 ± 20.41, P < 0. 05), overweight group (68. 81 ± 20. 48 vs 78.08 ±18.23, P<0.05) and obese group (68.81 ±20.48 vs 78. 69 ± 17.77, P<0.05); the score of normal weight group was significantly lower than the overweight group (74. 70 ±20. 41vs 78. 08 ±18.23, P<0.05). Gender Stratification showed that females with low body mass index had worse HRQOL than males. Conclusion The HRQOL of elderly hypertensive patients with low body mass index is significantly lower than normal weight patients, overweight patients and obese patients, the health promotion of elderly hypertensive patients with low body mass index should be paid more attentions, especially females with low body mass index.

As known so far,Sporosarcina pasteurii,or formally termed as Bacillus pasteurii,was considered as one of the most efficient biosystem which is capable of inducing biological mineralization through breaking down urea.Taking advantage of the ‘super power’ of bio-mineralization,Sporosarcina pasteurii has been successfully utilized in application of solidifying sand as a novel biological construction technology,termed as ‘bio-cementation’ Due to the nature of Sporosarcina pasteurii isolated from soil,non-pathogenicity has been observed,it was considered as a very environmentally friendly method.Recently,Sporosarcina pasteurii has been further applied into fields including environmental improvement and biomedicine.However,the mechanism under the strong Sporosarcina pasteurii mediated bio-mineralization is still not well understood.Here,the knowledge and the up-to-date studies about the biological mechanism of Sporosarcina pasteurii mediated bio-mineralization,and the utilization in construction,environment,and biomedicine are reviewed.

Objective To explore serum Cystain C (Cys C) level in chronic heart failure (CHF) patients and its relation?ship with cardiac function and ventricular remodeling. Methods Patients with heart failure (n=75) and healthy adult (n=35) were enrolled in this study. According to the NYHA classification,CHF patients is divided into NYHA Ⅱ, NYHAⅢand NYHAⅣ;CHF patients can also be divided into 2 groups base on their level of serum Cys C:Cys C>0.95 mg/L is defined as elevated serum Cys C group, serum Cys C≤0.95 mg/L is defined as normal serum Cys C group;According to left ventricu?lar ejection fraction (LVEF), CHF patients can also be divided into 2 groups:LVEF≥0.50 is defined as ejection fraction re?served group, LVEF<0.50 is defined as the ejection fraction reduced group. Cys C, N terminal B-type natriuretic peptide (NT-proBNP), serum creatinine(Scr),UREA and Echocardiography were analyzed in all groups and their correlation was studied. Results Serum Cys C level in CHF patients was obviously higher than that in healthy controls, and it increased with NYHA heart function classification;compared with normal Cys C group,Cys C elevated group presented higher NT-proBNP level but lower eGFR and LVEF (P<0.05);compared with ejection fraction reduced group, ejection fraction reserved group demonstrated lower NT-proBNP, LVEDD, LVMI and Cys C levels (all P<0.05);Correlation analysis revealed that Cys C is correlated with age, NT-proBNP, LVEF, LVEDD, Scr and UREA (r=0.411, 0.658, 0.465, 0.310, 0.552, 0.486, P<0.01). Conclusion Serum Cys C can be used to evaluate cardiac function of heart failure, and is associated with ventricular remodeling.

Abstract: Objective　To investigate the molecular characteristics and drug resistance of non-O1/non-O139 Vibrio cholerae in Zhongshan City, and to provide laboratory basis for cholera prevention and control. Methods　The strains of non-O1/non-O139 Vibrio cholerae isolated from sporadic patients and aquatic products from 2015 to 2021 in Zhongshan city were collected. The identification and cluster analysis of the strains were analyzed by matrix assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS), the ctxA virulence gene of strains were detected by real-time fluorescence quantitative PCR, the cluster analysis of the strains was analyzed by pulsed-field gel electrophoresis (PFGE), and the drug resistance of the strains were analyzed by microbroth dilution method. Results　From 2015 to 2021, 33 strains of non-O1/non-O139 Vibrio cholerae were isolated from Zhongshan City, including 28 strains from sporadic patients and 5 strains from aquatic products. Through MALDI-TOF-MS identification, 33 strains of non-O1/non-O139 Vibrio cholera can be identified to the level of species, and the identification results were all Vibrio cholerae. Among 33 non-O1/non-O139 Vibrio cholerae strains, 1 strain carried the ctxA virulence gene. The drug-resistant strains accounted for 69.7% (23/33), and the multidrug resistant strains accounted for 18.2% (6/33). A total of 7 kinds of drug resistance spectrum were produced, including 3 kinds of multidrug resistant spectrum, and showed drug resistance to 8 antibiotics, among which the resistance rates to streptomycin, cefazolin and compound sulfamethoxazole were above 30%. The 33 strains of non-O1/non-O139 Vibrio cholerae were divided into 32 PFGE fingerprints with a similarity ranging from 61.7% to 100%. MALDI-TOF-MS cluster analysis divided 33 non-O1/non-O139 Vibrio cholerae strains into two clusters. Conclusions The results of molecular typing of non-O1/non-O139 Vibrio cholerae in Zhongshan City presented diversity, and no significant correlation was found between PFGE and MALDI-TOF-MS cluster analysis. The strains demonstrated various degrees of resistance to certain antibiotics, and there were multidrug-resistant and toxigenic strains. Therefore, it is necessary to alert to the harmfulness of non-O1/non-O139 Vibrio cholerae and enhance monitoring.

Based on the infrared spectra of Lophatheri Herba and Commelinae Herba, one-dimensional infrared spectra, second derivative spectra and two-dimensional correlated spectra were used to find out the differences between Lophatheri Herba and its imitations, respectively. The common peak ratio and variant peak ratio dual-indexes sequential were calculated and established according to infrared spectra of eleven batches of herbs. Infrared spectral data of Lophatheri Herba cluster analysis was applied to explore the similarity between each sample. The grouping results trend of sequential analysis of dual-indexes and cluster analysis was accordant. The results showed that the differences could be found by multi-level identification, and the source and the quality of the herbs could be effectively distinguished by the two analysis methods. Infrared spectroscopy, used in the present work exhibited some advantages on quick procedures, less sample required, and reliable results, which could provide a new method for the identification of traditional Chinese medicine with the imitations and adulterants, and the control of quality and origin.

Objective To evaluate the clinical efficacy of a stroke unit combined with community health services for treating stroke survivors. Methods A total of 120 stroke patients were randomly divided into a " stroke unit combined with community medicine" group ( combined group) , a stroke unit group and a general treatment group. Patients in the former 2 groups were treated in a hospital stroke unit during their hospitali-zation. The general treatment group was given conventional medical treatment. After discharge, the combined group continued to receive regular rehabilitation therapy and guidance in the form of community medical services, while the stroke unit group received follow-up only. Assessment was by means of Fugl-Meyer scores, the Barthel index and self-rating on a depression scale ( SDS). The patients were assessed at admission, on discharge and 3 months after discharge. Results There were no significant differences in average limb motor function, ability in the activities of daily living ( ADL) or depressive mood among the 3 groups on admission, but at discharge, limb motor function and ADL ability in the combined group and stroke unit groups were significantly superior to those in the general therapy group. Limb motor function and ADL ability in the combined and stroke unit groups had improved further 3 months after discharge, with more significant improvements in the combined group. No significant change in depression was observed in any group at discharge, but average depression scores in the combined and stroke unit groups improved significantly in the 3 months after discharge, and there was a statistically significant difference between the combined group and the general group. Conclusion Supplementing the work of a stroke unit with community health services significantly improves stroke patients' recovery of limb motor function and ADL ability.

Background and purpose: Researches demonstrated that the butyric acid sodium salt (sodium butyrate, NaB) has effect on the inhibition of tumor cell proliferation, differentiation and apoptosis-promoting, while the mechanism on salivary adenoid cystic carcinoma(SACC) is still uncertain. This study mainly probed into the impact of different concentration of sodium butyrate on the migration and invasion of SACC cell line ACC-M, and its mechanism of action. Methods:MTT assay explored the optimal concentration of sodium butyrate on the cell ACC-M and the observation of cell growth. Transwell assay was used to detect the effects of sodium butyrate on the ACC-M cells on the aspact of invasion and migration ability. Fluorescence real-time quantitative PCR (RT-PCR) and Western blot were used to test respectively the expression of HMGB1, TLR4 mRNA and protein in ACC-M after functioned by 5 group drugs with different concentrations. Results:Compared with the control group, on the one hand, the concentration 0.625, 1.25, 2.5, 5 and 10 mmol/L of sodium butyrate could effectively inhibit cell proliferation and apparently showing concentra-tion-dependence (P<0.05);On the other hand, 5 sets concentration of sodium butyrate could also effectively inhibit invasion and migration ability of ACC-M cells in vitro (P<0.05), as well as reducing the expression of HMGB1, TLR4 mRNA and protein in ACC-M cells (P<0.05). Furthermore related analysis showed that the decline of TLR4 protein expression was positively correlated with inhibition of HMGB1 (r=0.810, P<0.05). Conclusion:Sodium butyrate has an effect on inhibiting ACC-M cell proliferation, signiifcantly reducing ACC-M cell invasion and migration capabilities, and reducing expression of HMGB1, TLR4 mRNA and protein, and both expression amount are positively correlated, Meanwhile the positively correlation suggests that sodium butyrate probably achieve the inhibition ability by lowering the expression of HMGB1, TLR4 mRNA and protein in ACC-M cell.

Objective: To examine the relationship between traditional Chinese medicine (TCM) constitutional types and health status among groups of different age or gender in the general population of China. Methods: Data of 8 448 cases were randomly sampled from a database of 21 948 cases of a cross-sectional survey on the TCM constitutional types and health status which was carried out in 9 provinces or municipalities of China (Jiangsu, Anhui, Gansu, Qinghai, Fujian, Beijing, Jilin, Jiangxi and Henan) according to gender and age structure of the Chinese population in 2005. Scores of health-related quality of life scale--the Medical Outcomes Study 36-Item Short-Form Health Survey (MOS SF-36)--were analyzed by Nemenyi test to compare the health status of individuals with different constitutional types. Results: Compared with the gentleness type, the MOS SF-36 scores of the 8 types of pathological constitution were significantly low (P<0.05) among groups of different age or gender. The MOS SF-36 score was the lowest in men of the qi-deficiency, qi-depression and blood-stasis types, while it was the lowest in women of the phlegm-dampness, qi-depression and qi-deficiency types. For the age group of 15 to 34, the special diathesis, qi-depression and blood-stasis types had the lowest MOS SF-36 scores; for the age group of 35 to 59, the qi-deficiency, qi-depression and blood-stasis types had the lowest MOS SF-36 scores; for the age group of over 60, the qi-deficiency, qi-depression and phlegm-dampness types had the lowest MOS SF-36 scores. Conclusion: In groups of different gender or age, the MOS SF-36 scores of the 8 types of pathological constitution were significantly lower than that of the gentleness type, indicating a deficient health status. The health status of different types of constitution showed different characteristics in groups of different gender or age.
