Objective To study the therapeutic effect of Xuefu Zhuyu Capsule combined with sacubitril valsartan on dilated cardiomyopathy.Methods A total of 70 patients with dilated cardiomyopathy who were hospitalized in the Hospital from January to December 2020 were selected as the research objects and random-ly divided into control group and experimental group,with 35 cases in each group.The control group was only treated with sacubitril valsartan,and the experimental group was treated with Xuefu Zhuyu Capsule combined with sacubitril valsartan.According to the patient's blood pressure and renal function,sacubitril valsartan was titrated from a small dose to the maximum dose.Xuefu Zhuyu Capsule was uesd 2.4 g each time,twice a day,and the treatment time was three months.The symptoms of heart failure,glycosylated hemoglobin(HbA1c),low density lipoprotein(LDL),total cholesterol(TC),triglyceride(TG),ALT,AST,N-terminal pro-brain natriuretic peptide(NT-proBNP),left ventricular end-systolic diameter(LVEDd),left ventricular end-dias-tolic diameter(LVEDs),ejection fraction(EF)and the incidence of arrhythmia were observed in the two groups after treatment.Results After treatment,the level of NT-proBNP in the experimental group was sig-nificantly lower than that in the control group(P＜0.05).There was no significant difference in LDL,TC,TG,LVEDd,LVEDs and EF between the two groups(P＞0.05).The incidence of atrial tachycardia and ven-tricular premature beat in the experimental group was higher than that in the control group(P＜0.05).Con-clusion Xuefu Zhuyu Capsule combined with sacubitril valsartan can significantly improve the symptoms of patients with heart failure and reduce the level of NT-proBNP,but it may increase the proportion of patients with atrial tachycardia and ventricular premature beats.

The incidence of ulcerative colitis(UC)is on the rise globally,but its pathogenesis has not yet been clarified.Existing studies suggest that UC is closely related to genetic susceptibility,impaired intestinal epithelial barrier,abnormal immune response,intestinal flora dysbiosis and environmental factors.Intestinal flora has the functions of substance metabolism,nutrient absorption,energy conversion,immune regulation and maintenance of intestinal mucosal barrier,and has been proved to play an important role in UC.This article reviewed the progress of research on intestinal flora and its metabolites in UC,thus providing theoretical basis and new ideas for the diagnosis and treatment of UC.

Objective:To investigate the mechanism by which non-enterotoxin-producing Bacteroides fragilis (NTBF) inhibits TNF-α-induced inflammatory responses in human normal colonic epithelial cells hcoEPIC, and explore new probiotic therapies for the prevention and treatment of colitis. Methods:The co-culture system of NTBF and hcoEPIC cells was established, and the adhesion and invasion ability of NTBF were detected, respectively. TNF-α was added to induce cellular inflammation after 4 h of co-culture of NTBF and hcoEPIC cells, and cell survival and apoptosis were detected by the CCK-8 assay and the AnnexinⅤ-FITC/PI assay respectively after 24 h. Key proteins of the NF-κB signalling pathway in hcoEPIC cells in different treatment groups were detected by Western blot and RT-qPCR, and the expression of downstream cytokines of this pathway incluing IL-1β, TNF-α and IL-10 were detected by ELISA. The effect of NTBF intervention on dextran sodium sulfate(DSS)-induced colitis mice was assessed by in vivo animal experiments. Results:NTBF adhered to hcoEPIC cells, and was non-toxic to the cells. Compared with control group, NTBF treatment alone did not affect cell survival and apoptosis of hcoEPIC cells ( P>0.05), but significantly reduced cell damage and apoptosis induced by TNF-α ( P<0.05); Compared with the TNF-α treatment alone group, the expression levels of p-NF-κB p65 and p-IκBα protein as well as NF-κB and IκBα mRNA were significantly reduced ( P<0.05); the production of IL-1β and TNF-α in the cell supernatant was reduced and the release of IL-10 was increased ( P<0.05). Animal experiments demonstrated that NTBF was indeed effective in alleviating DSS-induced colitis in ulcerative colitis model mice, which was mainly manifested by inhibiting weight loss, lowering DAI scores, improving colonic shortening, and attenuating colonic pathological damage in colitis-induced mice. Conclusions:NTBF may inhibit TNF-α-induced inflammatory responses in colonic epithelial cells by down-regulating the NF-κB pathway.

In recent years, with the development of metabolic reprogramming research, people have changed their understanding of the biological effects of immune cells. Under the stimulation of inflammatory response, immune cells re-regulate their metabolism and bioenergetics, provide energy and substrates for cell survival, and initiate immune effect functions. Nod-like receptor protein 3 (NLRP3) inflammasome, as an important component of the innate immune system, has been shown to sense metabolites such as uric acid and cholesterol crystals, and can be inhibited by metabolites such as ketones. It is also regulated by mitochondrial reactive oxygen species and glycolytic components (such as hexokinase). Recent studies have shown that a variety of metabolic pathways converge as effective regulators of NLRP3 inflammasome. The paper reviews the metabolic regulatory pathways and specificity of NLRP3 inflammasome activation, and its role in renal diseases.

Objective:To analyze the perioperative clinical characteristics of patients with oral cancer underwent radical resection and flap reconstrution and the nursing managements.Methods:From January 2020 to December 2020, 658 patients with oral cancer underwent radical resection and flap reconstrution in the Department of Oral and Maxillofacial Surgery, Sun Yat-sen Memorial Hospital, Sun Yat-sen University were retrospectively analyzed. All patients were divided into the elderly group (≥60 years) and the younger group (< 60 years), including 279 cases in the elderly group and 379 cases in the younger group. The perioperative clinical data of the patients were collected, and the perioperative general situation, postoperative complications and influencing factors of complications were analyzed.Results:There were differences between the two groups in the aspects of sex ( χ2 = 12.38, P<0.001), preoperative BMI ( t = 2.43, P = 0.015), smoking history ( χ2 = 18.34, P<0.001), preoperative anesthesia grade ( χ2 = 25.61, P = 0.001), preoperative coexisting disease ( χ2 = 46.97, P<0.001), whether oral floor or tongue cancer ( χ2 = 16.68, P<0.001), whether free flap ( χ2 = 6.81, P = 0.003), operation time ( t = 2.19, P = 0.029), preoperative test index hemoglobin ( t = 4.96, P<0.001), albumin ( t = 5.44, P<0.001), D-dimer( Z = -13.52, P<0.001), calcium levels ( t = 4.07, P<0.001) and postoperative complications ( χ2 = 14.55, P<0.001). Multivariate analysis of postoperative complications showed that the age ( OR = 1.021, 95% CI = 1.005-1.037, P = 0.011), preoperative D-dimer ( OR = 1.219, 95% CI = 1.026-1.447, P = 0.024) and the preoperative coexisting disease ( OR = 1.642, 95% CI = 1.108-2.432, P = 0.013) were the risk factors for the postoperative complications. Multivariate analysis of discharge with tube showed that the age ( OR = 1.017, 95% CI = 1.003-1.031, P = 0.017), preoperative BMI ( OR = 0.917, 95% CI = 0.873-0.963, P = 0.001), whether oral floor or tongue cancer ( OR = 2.135, 95% CI = 1.475-3.091, P<0.001), and operation time ( OR = 1.220, 95% CI = 1.120-1.328, P<0.001) were the related factors for the discharge with tube. Conclusion:In view of the above risk factors, it is beneficial for the physical and mental recovery of patients to pay attention to preoperative evaluation, make adequate preoperative preparation, postoperative nursing and observation, improve swallowing function training, prepare for discharge, pay attention to continuous nursing, and establish a tertiary hospital-community-family rehabilitation system.

Objective:To assess the clinical result of repeated combined detrusor-trigone botulinum toxin A(BTX-A)injection and intermittent catheterization(IC) for male adults with neurogenic detrusor overactivity (NDO) and urinary incontinence(UI) secondary to spinal cord injury(SCI).Methods:From January to August 2021, the data of 43 adult male patients with NDO and UI secondary to SCI who received repeated trigone-including intradetrusor BTX-A injection in Guangdong Provincial Work Injury Rehabilitation Hospital were retrospectively analyzed. The mean age of the patients was (29.1±10.7) years. The mean incontinence specific quality of life (I-QOL) was (39±4.8). The UI episodes was (11.9±2.6), mean voiding volume was (170.7±20.1)ml, mean maximum detrusor pressure at first NDO was (81.4±19.6) cmH 2O and mean volume at first NDO was (169.1±40.0)ml.All patients received trigone-including intradetrusor BTX-A (300 U, 30 sites) injection for four times and IC. Clinical data including I-QOL, bladder diary, video-urodynamic test and adverse events were recorded at baseline and 12 weeks after each injection. Results:Mean interval between four injections were (220.6±27.4), (222.8±24.1) and (224.4±39.0) d ( P=0.13). Compared with baseline data before first injection, mean I-QOL after the first, second, third and fourth injection increased to (54.9±9.1), (56.1±7.9), (61.7±9.1) and (68.8±8.9) (all P<0.001). The number of urinary incontinence cases decreased to 36, 35, 35 and 33 (all P<0.05). The mean urinary incontinence episodes per day decreased to (4.4±0.6), (3.8±0.4), (2.2±0.5) and (2.1±0.3)(all P<0.001). Mean voiding volume increased to (288.3±40.2), (300.0±38.6), (316.9±46.8) and (319.5±36.7) ml (all P<0.001). Mean maximum detrusor pressure at first NDO decreased to (29.4± 11.0), (26.1±8.7), (20.3±5.9) and (18.5±6.0) cmH 2O (all P<0.001) and mean volume at first NDO increased to (270.0±48.7), (284.9±51.3), (287.7±47.9) and (303.0±46.2) ml (all P<0.001), respectively. Compared with four injections, no difference in response was found in the mean I-QOL, the number of urinary incontinence cases, mean urinary incontinence episodes mean voiding volume, mean maximum detrusor pressure at first NDO and mean volume at first NDO (all P>0.05). No de novo VUR occurred and 2 cases of grade Ⅱ VUR at baseline had resolved after the first injection. 9 patients experienced serious gross hematuria within first week after injection, but the urine returned to clear by prolonging the catheter indwelling time or bladder irrigation. 12 patients with active urinary tract infection were treated with indwelling catheter and sensitive antibiotics. Patients continued IC when the symptoms, signs and laboratory examination were normal. Conclusions:Combined detrusor-trigone BTX-A injection and IC could help decrease detrusor pressure, restore some of the lower urinary tract function and improve the quality of life for male patients with NDO and UI secondary to SCI. Repeated injection is as effective and safe as the first injection.

Background Evidence on the association between greenness and adiposity in children and adolescents is inconsistent and mostly from developed countries. Relatively limited evidence is from China. Objective To assess the association between greenness and adiposity in children and adolescents based on satellite remote sensing data. Methods From 2016 to 2018, a cross-sectional study was conducted among 52316 children and adolescents aged 5-18 years in three cities in the Pearl River Delta region of China. Basic sociological and demographic characteristics of the population and adiposity levels were collected through questionnaires. Land Remote-Sensing Satellite (Landsat) data and moderate-resolution imaging spectroradiometer (MODIS) products were used to quantify the greenness around the schools and homes, including normalized difference vegetation index (NDVI), vegetation continuous field (VCF), soil-adjusted vegetation index (SAVI), and enhanced vegetation index (EVI) calculated within 500 m and 1000 m buffers centered around the participants' homes or schools. A restricted cubic spline function was used to assess the exposure-response relationship. After categorizing greenness levels into quartiles with the first quartile as the reference, two-level generalized linear models were applied to assess the change in body mass index z-scores (zBMI) and the risk of overweight of children and adolescents in higher quartiles relative to the lowest quartile. In addition, counterfactual framework modelling was applied to assess the potential mediation effects of PM_2.5 and NO₂, and physical activity levels on the associations between greenness and adiposity levels. Results Of the 52316 children included, 8406 (16.1%) were overweight. A non-linear negative association of the level of greenness around the homes or schools and zBMI was found, with a significant lower zBMI in children and adolescents when a certain level of greenness was reached. After adjusting for confounders, the participants in the highest quartile had a significantly lower level of zBMI and a significantly lower risk of overweight compared with those in the lowest quartile of NDVI_{500 m} and VCF_{500 m}. The estimate change (\begin{document}$b$\end{document}) for zBMI was −0.07 (95%CI: −0.10-−0.04) and the odds ratio (OR) for overweight was 0.92 (95%CI: 0.85-0.99) for the students in the highest NDVI_{500 m} quartile based on home address compared to those in the lowest quartile. Significant negative associations were also observed when 1000 m buffer, SAVI, and EVI were used. The mediation analysis showed that PM_2.5 and NO₂ partially mediated the negative association of NDVI_{500 m} with zBMI , and the proportions of mediation were 50% (95%CI: 20%-80%) and 90% (95%CI: 50%-160%), respectively while no significant mediation effect was observed for physical activity level. Conclusion Higher levels of greenness surrounding homes or schools may be associated with a reduced risk of overweight and decreased zBMI in children and adolescents, and such associations may be partially mediated by reducing air pollutant concentrations.

Objective: To assess clinical effect and safety of botulinum toxin A injection in external urethral sphincter for male patient with neurogenic detrusor underactivity(DU). Methods: A prospective and self-controlled trail was conducted from August 2012 to October 2017. Male patients with nerve injury, dysuria more than 6 months, DU(bladder contractility index less than 100) were enrolled in this study. Exclusion criteria included patients with acute urinary tract infection, bladder stone, benign prostate hyperplasia, urethral stricture and urethral diverticulum.100 IU BTX-A was dissolved in 4ml normal saline, and the solution of BTX- A was injected into 4 different points(3-o’clock, 6-o’clock, 9-o’clock, and 12-o’clock) in external urinary sphincter with each point of 1ml solution. Patients were evaluated at baseline and 12 weeks after injection. The outcomes included post void residual (PVR), maximum flow rate (Q_max), maximum detrusor pressure during voiding phases (P_det.max), maximum urethral closure pressure (MUCP), the case number of intermittent catheterization (IC)and the score of quality of life (QOL score). Adverse events were also recorded. Results: A total of 58 male patients (all from Guangdong provincial work injury rehabilitation hospital)with mean age 28.6 years suffered from cerebral palsy (n=2), cerebrovascular accident(n=19)and spinal cord injury(n=37) were included into the study. Compared to baseline data, significant difference were observed at week 12 in PVR (56.68 ml vs. 280.11 ml, P<0.001), P_det.max(23.95 cmH₂O vs. 30.01 cmH₂O, P=0.019), Q_max(6.74 ml/s vs. 3.28 ml/s, P=0.042), MUCP(48.25 cmH₂O vs. 79.34 cmH₂O, P<0.001), the case number of IC(40 vs. 58, P<0.001) and QOL score(3.63 vs.5.22, P<0.001) respectively. 5 cases developed perineal pain and 16 cases developed mild transient haematuria. These adverse events were disappeared by medical symptomatic treatment during 3-5 days. Conclusions BTX-A externalurethral sphincter injections help reduce urethra resistance and also improve the quality of life for patients with neurogenic detrusor underactivity.

Goose hemorrhagic polyomavirus (GHPV) is not a naturally occurring infection in geese in China; however, GHPV infection has been identified in Pekin ducks, a domestic duck species. Herein, we investigated the prevalence of GHPV in five domestic duck species (Liancheng white ducks, Putian black ducks, Shan Sheldrake, Shaoxing duck, and Jinyun Sheldrake) in China. We determined that the Jinyun Sheldrake duck species could be infected by GHPV with no clinical signs, whereas no infection was identified in the other four duck species. We sequenced the complete genome of the Jinyun Sheldrake origin GHPV. Genomic data comparison suggested that GHPVs share a conserved genomic structure, regardless of the host (duck or geese) or region (Asia or Europe). Jinyun Sheldrake origin GHPV genomic characterization and epidemiological studies will increase our understanding of potential heterologous reservoirs of GHPV.
