Objective:To evaluate the predictive value of anthropometric indicators in predicting cardiovascular risk in the population with metabolic syndrome(MS).Methods:A cross-sectional study was used to analyze the correlation between anthropometric measures and cardiovascular risk in subjects with MS. Cardiometabolic risk was assessed with cardiometabolic risk index(CMRI). Receiver operating characteristic(ROC) curve analysis was used to assess the predictive power of anthropometric measures for cardiometabolic risk.Results:(1) The anthropometric measures [body mass index(BMI), waist-hip ratio(WHR), waist-to-height ratio(WtHR), body fat percentage(BFP), visceral fat index(VFI), conicity index(CI), a body shape index(ABSI), body roundness index(BRI), abdominal volume index(AVI)] in the MS group were significantly higher than those in the non-MS group( P<0.05). Moreover, there were significant differences in CMRI score and vascular risk between the two groups( P<0.05). (2) Logistic regression analysis showed that the cardiovascular risk was increased with the increases of BMI, VFI, WHR, WtHR, CI, BRI, and AVI after adjusting for confounding factors in the overall population, the non-MS population, and the MS population( P<0.05). (3) In the ROC analysis, the AUC values of BMI, VFI, and AVI were 0.767, 0.734, and 0.770 in the overall population; 0.844, 0.816, and 0.795 in the non-MS population; 0.701, 0.666, and 0.702 in the MS population, respectively. For the overall population and non-MS population, the optimal cut points of BMI to diagnose high cardiovascular risk were 26.04 kg/m 2 and 24.36 kg/m 2; the optimal cut points of VFI were 10.25 and 9.75; the optimal cut points of AVI were 17.3 cm 2 and 15.53 cm 2, respectively. In the MS population, the optimal cut point as a predictor of high cardiovascular risk in young and middle-aged men with MS was 27.63 kg/m 2, and the optimal cut point of AVI in women was 18.08 cm 2. Conclusion:BMI, VFI, and AVI can be used as predictors of cardiovascular risk in the general population. BMI can be used as a predicator of high cardiovascular risk in young and middle-age men with MS. AVI can be used as a predicator of high cardiovascular risk in women with MS.

Objective To investigate the role of proanthocyanidins (PC) in lipopolysaccharide (LPS)-induced inflammatory response and its possible mechanism in RAW264.7 macrophages. Methods RAW264.7 macrophages were cultured and treated with PBS and different concentrations of PC for 24 hours, followed by 1 μg/mL LPS for 6 hours. Real-time PCR was used to detect the mRNA expression of interleukin1β (IL-1β), IL-6, monocyte chemoattractant protein 1 (MCP-1), tumor necrotic factor α (TNF-α), IL-4 and arginase 1 (Arg1) in RAW264.7 macrophages. Flow cytometry was used to detect the effects of PBS group, LPS group and PC combined with LPS group on M1 and M2 polarization of macrophages. The protein expressions of silenced information regulator 1 (SIRT1), nuclear factor kappa B p65(NF-κB p65) and acetylated NF-κB p65 (Ace-p65) were detected by Western blot analysis after different concentrations of PC treatment. Co-immunoprecipitation assay was used to detect the binding effect of SIRT1 to NF-κB p65 in macrophages treated with PC. Results Compared with PBS group, the mRNA expression of macrophage pro-inflammatory cytokines IL-1β, IL-6, MCP-1 and TNF-α decreased and the mRNA expression of anti-inflammatory factors IL-4 and Arg1 increased in PC group. Compared with LPS group, PC combined with LPS group could significantly inhibit M1 polarization and promote M2 polarization of macrophages. With the increase of PC concentration, the expression of SIRT1 was up-regulated, and NF-κB p65 protein did not change significantly. The expression of Ace-p65 protein decreased significantly when treated with high concentration of PC. Conclusion PC can significantly alleviate the LPS-induced inflammatory response by up-regulating the expression of SIRT1 and inhibiting NF-κB pathway in RAW264.7 macrophages.

OBJECTIVE To investigate the efficacy and safety of different doses of zinc in the treatment of diarrhea in children， and to provide a reference for clinical safe and rational drug use. METHODS Retrieved from PubMed， Cochrane Library， Embase database， randomized controlled trials about zinc （zinc group） versus placebo or conventional treatment （control group） in the treatment of diarrhea in children were collected from the inception to October 2022. Then， the quality of the included literature was evaluated by the Cochrane Handbook 6.0， and meta-analysis and sensitivity analysis were performed by RevMan 5.3 software. RESULTS Finally， 25 RCTs were included， with a total of 8 618 children. The results of meta-analysis showed that in terms of duration of diarrhea， in zinc ＜20 mg group， the zinc group was significantly shorter than the control group [SMD＝ －0.39， 95%CI（－0.71， －0.08）， P＝0.01]， but in subgroups of ＜6 months old， there was no significant difference between the two groups [SMD＝0.01， 95%CI（－0.10， 0.11）， P＝0.88]. In zinc 20 mg group， the zinc group was significantly shorter than the control group [SMD＝－0.52， 95%CI（－0.80， －0.23）， P＝0.000 3]. In zinc ＞20 mg group， the zinc group was significantly shorter than the control group [SMD＝－0.83， 95%CI（－1.39， －0.27）， P＝0.004]. In zinc ＞10 mg （age ≤12 months） or zinc ＞ 20 mg （age ＞12 months） group （short for “constant dose group”）， the zinc group was significantly shorter than the control group [SMD＝－0.16， 95%CI（－0.27， －0.06）， P＝ 0.003]. In the aspect of diarrhea rate after 7 days of treatment，there was no significant difference in the diarrhea rate after 7 E-mail：lihuiying@etyy.cn days of treatment between the zinc group and the control group： in zinc ＜20 mg group[OR＝1.28，95%CI （0.96，1.70），P＝0.09]， in zinc 20 mg group [OR＝0.40， 95%CI （0.15，1.01），P＝ 0.05]， in constant dose group [OR＝0.64， 95%CI （0.28， 1.44）， P＝0.28]. In terms of vomiting rate， in zinc ＜20 mg group， the vomiting rate of zinc group was significantly higher than that of the control group [OR＝2.13， 95%CI （1.68， 2.70）， P＜0.001]； in constant dose group， vomiting rate of zinc group was significantly higher than that of the control group [OR＝1.84， 95%CI （1.44， 2.34）， P＜0.001]. CONCLUSIONS Zinc can significantly shorten the duration of diarrhea in children（6 months and above）， but low doses can increase the risk of vomiting， which should be taken attention in clinical.

Colorectal cancer is a disease with high morbidity and mortality. Colorectal cancer has a poor prognosis, duing to the current limited treatment methods and can not achieve satisfactory treatment results. Therefore, how to diagnose colorectal cancer patients early and improve the prognosis has always been one of the problems in the medical and scientific research circles. As researchers gradually learn more about the intestinal flora including Fusobacterium nucleatum, the targeted treatment has been applied to the experimental research and clinical treatment of colorectal cancer. This paper reviews the research progress of Fusobacterium nucleatum on the pathogenesis, early diagnosis, prognosis and treatment of colorectal cancer in recent years.

Immune checkpoint inhibitors (ICIs) is a negative regulatory factor antibody, which activates T cells to play an anti-tumor effect in immunotherapy, and can also cause immune-related adverse responses, thereby inducing a series of immune related adverse events (irAEs). Among these irAEs, although the incidence of ICIs-related myocarditis is very low, the fatality rate is significantly higher than other adverse reactions, close to 50%. Clinicians should be vigilant when applying ICIs, but the pathogenesis of ICIs-related myocarditis is still unclear. This article combines the recent research results of ICIs to summarize the mechanism and clinical manifestations of ICIs-related myocarditis, so as to improve clinicians' understanding of the adverse reactions.

Anastomotic leakage is one of the most serious complications following colorectal surgery. Occurrence of anastomotic leakage is concealed and numerous risk factors might relate to anastomotic leakage, which greatly affect the postoperative outcomes and life quality of patients. Therefore, it is necessary to recognize risk factors to predict anastomotic leakage in advance and adopt available treatments to reduce the incidence. This review summarized the risk factors of postoperative anastomotic leakage base on two aspects, and so on. Perioperative related factors and biological markers, aiming to provide a theory for predicting anastomotic leakage then improving the treatment outcomes of colorectal cancer patients .

Gut microbiota plays an important role in the development of colorectal cancer, such as Fusobacterium Nucleatum, Peptostreptococcus and Streptococcus thermophilus. At present, Surgery is the mainly treatment strategy of colorectal cancer patients, supplemented by postoperative radiotherapy and chemotherapy. The influence of gut microbiota on colorectal cancer is not limited to the tumor itself. After tumor resection, gut microbiota is still in a state of disorder, which will affect the short-term and long-term prognosis of patients. Therefore, understanding the relationship between gut microbiota and prognosis of colorectal cancer is helpful to improve the prognosis of patients and reduce postoperative complications. In this review, the author will summarize the influence of gut microbiota on short-term and long-term prognosis of colorectal cancer patients.

Objective:To analyze the characteristics of malaria epidemic situation before and after malaria elimination in Qiandongnan Prefecture, and to provide the basis for establishment of effective strategies and measures to consolidate the achievements of malaria prevention and control.Methods:The data of malaria cases in 16 counties (cities) of Qiandongnan Prefecture from 2005 to 2018 were collected, and descriptive epidemiological method was used to analyze the infection rate of Plasmodium among local residents and floating population before (2005-2011) and after (2012-2018) elimination of malaria, and the characteristics of population distribution, seasonal distribution, species of Plasmodium and types of malaria vectors were analyzed. Results:Before elimination of malaria, total of 1 412 cases of malaria were reported, among those cases, 1 361 cases were local cases, accounting for 96.39% of the total cases. After elimination of malaria, total of 17 cases were reported, all of them were imported cases. After comparison of malaria cases before and after the elimination, the proportion of people aged from 18 to 60 was 70.54% (996/1 412) before the elimination, all 17 imported cases were 18-60 years old after the elimination, and the proportion of children/students decreased from 24.65% (348/1 412) before the elimination to 0 after the elimination. The peak incidence of malaria cases before the elimination was from June to October, and cases occurred every month. After the elimination, the imported cases were sporadic. Plasmodium vivax was the main species of Plasmodium before the elimination (98.58%, 1 392/1 412), and Plasmodium falciparum was mainly imported after the elimination (70.59%, 12/17). Before and after the elimination, Anopheles sinensis, the malaria vector, was the dominant population, but no distribution of Anopheles minimus and Anopheles anthropophagus was found after 2015. Conclusions:After the elimination of malaria in Qiandongnan Prefecture, there is a risk of local malaria cases caused by imported cases. It is suggested that local authorities should focus on the treatment of suspected malaria cases and vector surveillance of overseas returnees in the future.

Peritoneal adhesions are fibrous tissues that tether organs to one another or to the peritoneal wall and represent the major cause of postsurgical morbidity. Enterolysis at repeat surgeries induces adhesion reformation that is more difficult to prevent than primary adhesion. Here we studied the preventive effects of different approaches of berberine treatment for primary adhesion, and its effects on adhesion reformation compared to Interceed. We found the primary adhesion was remarkably prevented by berberine through intraperitoneal injection 30 min before abrasive surgery (pre-berberine) or direct addition into injured cecum immediately after the surgery (inter-berberine). Rats with adhesion reformation had a more deteriorative collagen accumulation and tissue injury in abrasive sites than rats with primary adhesion. The dysregulated TIMP-1/MMP balance was observed in patients after surgery, as well as adhesion tissues from primary adhesion or adhesion reformation rats. Inter-berberine treatment had a better effect for adhesion reformation prevention than Interceed. Berberine promoted the activation of MMP-3 and MMP-8 by directly blocking TIMP-1 activation core, which was reversed by TIMP-1 overexpression in fibroblasts. In conclusion, this study suggests berberine as a reasonable approach for preventing primary adhesion formation and adhesion reformation.

Objective:To investigate the distribution characteristics of bacteria in urine of patients with ureteral stent crusting.Methods:Thirty-five patients who underwent ureteral stent placement at the Shandong Provincial Third Hospital, Shandong University Qilu Hospital, Jinan Central Hospital, and Jinan Jigang Hospital were selected from October, 2018 to March, 2019(the clinical study registration number is ChiCTR1800020025). The inclusion criteria were patients who had the stent intubated for 4 weeks after ureteroscopic lithotripsy, aged between 18 and 65 years. Exclusion criteria were patients with positive urine bacterial culture, severe gross hematuria, recent oral antibiotics, and patients with significant residual stones. This clinical study uses a cross-sectional study method, and those patients were divided into crusting group (n=23) and non-crusting group (n=12) according to the presence or absence of stent crusting. On the day of extubation, urine of the patients was collected for bacterial 16s DNA detection. The distribution characteristics of bacteria in urine of the two groups were analyzed using UPARSE, UCHIME and RDP calssifier. The total number of bacteria species, bacterial abundance and bacterial species with large-scale abundance in urine of the two groups were determined. The quantity of bacteria species and bacterial abundance in the urine between the two groups were compared, and the bacterial species with large-scale abundance in urine of the patients with stent crusting were identified.Results:There were no significant differences in general information such as age, body mass index, gender, affected side, type of stent tube, and stone composition between the two groups. Using 16s DNA sequencing to detect the bacteria in the urine of the two groups revealed that the number of bacterial species with abundance >1% was 11, and the number of bacterial species with abundance >0.01% was 74 in the crusting group. In the non-crusting group, the number of bacterial species with abundance >1% and >0.01% was 7 and 11, respectively. Compared with the non-crusting group, the number of bacterial species with abundance >1% in the crusting group was significantly larger ( t=5.12, P=0.000). In the crusting group, bacterial species with the top three abundance were g_Lactobacillus (23.1%), g_Bacteroides (18.8%) and g_norank_Bacteroides (17.1%). In the non-crusting group, bacterial species with the top three abundance were g_Escherichia-Shigella (32.2%), g_Enterococcus (24.9%) and g_Pseudomonas (18.2%). The three bacteria with the greatest difference between the two groups were g_ Lactobacillus ( P=0.010), g_Bacteroides ( P=0.004) and g_norank_Bacteroides ( P=0.004), respectively. Conclusion:The species and quantity of bacteria in the urine of patients with stent crusting are both significantly larger than those of patients without stent crusting. Bacteroides with larger-scale abundance in the urine of patients with stent crusting may promote the deposition of crystals on the stent wall through its structure, function and urease positive characteristics.
