RESUMEN
Objective:To systematically evaluate the correlation between C-reactive protein (CRP) and postmenopausal osteoporosis.Methods:PubMed, EMbase, Cochrane library, China biomedical literature database, China HowNet and Wanfang database were searched by computer to collect the clinical research literature related to CRP and postmenopausal osteoporosis. The retrieval period was from the establishment of the database to April 1, 2021. The two researchers screened the literature according to the inclusion and exclusion criteria, extracted the data and evaluated the quality, Revman5.3 software was used for meta-analysis.Results:A total of 12 studies were included, including 778 cases in postmenopausal osteoporosis group and 933 cases in non osteoporosis group. The results of combined analysis showed that the level of CRP in postmenopausal osteoporosis group was higher than that in non osteoporosis group, and the difference was statistically significant (standardized mean difference (SMD)=0.55, 95% CI (0.03, 1.07), P=0.04). Further subgroup analysis according to different grouping criteria and CRP detection methods showed that the level of CRP in patients with osteoporosis was higher than that in normal bone group ( SMD=0.88, 95% CI (0.07,1.69), P=0.03). There was no significant difference in CRP level between osteoporosis group and osteopenia Group (SMD=0.13, 95% CI (-0.05, 0.31), P=0.15). There was no correlation between CRP levels detected by automatic analyzer, chemiluminescence immunoassay and enzyme-linked immunosorbent assay and postmenopausal osteoporosis. The level of CRP in postmenopausal osteoporosis group detected by immunoturbidimetry was higher than that in non osteoporosis group (SMD=1.50, 95% CI (1.10,1.90), P<0.01). Conclusion:CRP level is related to postmenopausal osteoporosis. High CRP level may be a risk factor for postmenopausal osteoporosis.
RESUMEN
Food-borne pathogens pose great risks to human health and public safety, and the formation of biofilm exacerbates their pathogenicity and antimicrobial resistance. Enzymes can target special substances in the biofilm to disintegrate the biofilm of food-borne pathogens, which has great potential for applications. This review summarized the progress of using enzymes to disintegrate the biofilms of food-borne pathogens, highlighting quorum-quenching enzymes, C-di-GMP metabolic enzymes, as well as extracellular matrix hydrolases. Finally, challenges and perspectives on developing enzymes into effective products for disintegrating the biofilms of food-borne pathogens were discussed.

We evaluated the tolerance and pathogenesis of foodborne pathogens with a simulated gastro-intestinal tract model that simulates the chemical, physical and biological effects of human digestion process under laboratory conditions. This could be used to study the tolerance, pathogenesis, gut microbiota interaction and vaccine development of foodborne pathogens, so as to contribute to control and treatment of foodborne pathogens. This review introduces the applications of simulated gastro-intestinal tract model tp evaluate foodborne pathogens, which includes in-vitro static gastro-intestinal model, in-vitro dynamic gastro-intestinal model, conventional animal model and humanized animal model. And the concepts and characteristics of all models are described in detail. Also, the shortcomings of existing models are analyzed, and improvements of artificial gastro-intestinal tract model are prospected. In conclusion, this review could provide comprehensive data for promoting the progress of studying tolerance and pathogenesis of foodborne pathogens.

RESUMEN
@#ObjectiveTo compare the effect of rehabilitation training after surgical intervention of knee stiffness (SIKS) between femoral nerve block (FNB) and epidural nerve block (ENB).Methods60 patients undergoing SIKS at one knee joint were randomly assigned to two groups: 40 patients accepting a catheter for FNB in group A and 20 patients accepting a catheter for ENB in group B. All patients participated in passive rehabilitation therapy (PRT) and active rehabilitation therapy (ART) at 12 hours, 24 hours, 36 hours, and 48 hours after operation. 10 ml of lidocaine were applied via these catheters before rehabilitation therapy. The visual analogue score (VAS) for pain in PRT, the time needed from the end of PRT to the start of ART, and the incidence of side effects such as hypotension or nausea were recorded.ResultsThere was no significant difference in VAS between groups A and B. The time needed from the end of PRT to the start of ART in group A was significantly less than that of group B. The incidence of hypotension or nausea in group A was significantly less than those of group B.ConclusionFNB provides the same analgesic effect as ENB, has less time needed from the end of PRT to the start of ART, and lowers incidence of hypotension or nausea.
