BACKGROUND:The morphological indexes of ankle point may change after ankle fracture,and there is a certain correlation between the coronal angle change of ankle point and the functional recovery of ankle joint.Most previous studies have studied the height recovery of ankle point after surgery,so the correlation between the fluctuation of coronal angle of ankle point and the functional recovery of ankle joint after ankle fracture has certain reference significance. OBJECTIVE:To investigate the effect of coronal angle change of ankle point on joint function recovery after ankle fracture. METHODS:A total of 86 patients with ankle fracture who underwent surgical treatment were selected as the study objects,and were divided into excellent group(n=45)and poor group(n=41)according to the results of American Orthopaedic Foot&Ankle Society(AOFAS)hindfoot-ankle score during the last follow-up,and the general data of the two groups were compared.The morphological indexes of ankle points on the affected side and healthy side were compared after surgery based on ankle acupoints and lateral X-rays of the ankle joint,including the width and depth of ankle points,coronal angle and sagittal angle,and the difference of ankle points between the affected side and healthy side,and further comparison and analysis were conducted in each group.A joint model was constructed and Cox regression analysis was used to evaluate the relationship between coronal angle fluctuation and joint function recovery.Least absolute shrinkage and selection operator regression method and multivariate Logistic regression were used to analyze the risk factors affecting the recovery of joint function.The patients were divided into 5-quartile array(Q1-Q5)according to the angle of coronal position at ankle point from low to high.The clinical data characteristics of the five groups were compared,and the correlation between the change of coronal position at ankle point and the risk of poor recovery of joint function was analyzed by multivariate Logistic regression.A restricted cubic spline Logistic regression model was established to analyze the dose-response relationship.The prediction model of regression equation y=1-1/(1+e-z)was established and verified. RESULTS AND CONCLUSION:(1)The width and depth of ankle point on the affected side,coronal angle and sagittal angle were significantly higher than those on the healthy side(all P<0.05),and compared with the excellent group,the difference of ankle point width,depth difference,coronal angle difference and sagittal angle difference were greater in the poor group(P<0.05).(2)The combined model showed that the risk of poor joint function was increased by 3%for every 1? increase in coronal angle,regardless of whether the angle was within the normal range.(3)Least absolute shrinkage and selection operator regression and multivariate Logistics regression analysis showed that after adjusting for potential confounding factors,it was found that age,lack of functional exercise in early stage,no calcaneal traction,failure to remove internal fixation,postoperative complications,and increased ankle coronal angle were independent risk factors for joint function recovery(P<0.05).(4)The coronal angle within 3 months after surgery was independently correlated with the risk of poor joint function recovery(OR=1.57,95%CI:1.38-1.76,P=0.002),and the trend test of the coronal angle from low to high quintile in each postoperative period had statistical significance(Ptrend<0.001).(5)Restricted cubic spline model analysis showed that there was no nonlinear relationship between the coronal angle change of ankle point and the risk of poor joint function recovery in males or females.Through Bootstrap self-sampling,the prediction model has good differentiation and accuracy.(6)The reduction of coronal angle of ankle point after ankle fracture plays a significant role in promoting the recovery of joint function.Therefore,the detection of coronal angle of ankle point after ankle fracture is helpful to understand the recovery of joint function of patients.

[Objective] To evaluate the efficacy and safety of sacral neuromodulation (SNM) in the treatment of patients with benign prostatic hyperplasia (BPH) complicated with underactive bladder (UAB) who respond poorly to transurethral resection of the prostate (TURP). [Methods] A retrospective analysis was performed on 10 patients with BPH and UAB treated with TURP by the same surgeon in Zhongda Hospital Southeast University during Jan.2018 and Jan.2023.The residual urine volume was not significantly relieved after operation, and the maximum urine flow rate and urine volume per discharge were not significantly improved.All patients underwent phase I SNM, and urinary diaries were recorded before and after surgery to observe the average daily frequency of urination, volume per urination, maximum urine flow rate, and residual urine volume. [Results] The operation time was (97.6±11.2) min.During the postoperative test of 2-4 weeks, if the residual urine volume reduction by more than 50% was deemed as effective, SNM was effective in 6 patients (60.0%). Compared with preoperative results, the daily frequency of urination [(20.2±3.8) times vs. (13.2±3.2) times], volume per urination [(119.2±56.7) mL vs. (246.5±59.2) mL], maximum urine flow rate [(8.7±1.5) mL/s vs. (16.5±2.6) mL/s], and residual urine volume [(222.5±55.0) mL vs. (80.8±16.0) mL] were significantly improved, with statistical significance (P<0.05). There were no complications such as bleeding, infection, fever or pain.The 6 patients who had effective outcomes successfully completed phase II surgery, and the fistula was removed.During the follow-up of 1 year, the curative effect was stable, and there were no complications such as electrode displacement, incision infection, or pain in the irritation sites.The residual urine volume of the other 4 unsuccessful patients did not improve significantly, and the electrodes were removed and the vesicostomy tube was retained. [Conclusion] SNM is safe and effective in the treatment of BPH with UAB patients with poor curative effects after TURP.

Background::Patients who undergo coronary artery bypass grafting (CABG) are known to be at a significant risk of experiencing long-term adverse events, emphasizing the importance of regular assessments. Evaluating health-related quality of life (HRQoL) serves as a direct method to gauge prognosis. Our objective is to ascertain the prognostic significance of consecutive HRQoL assessments using the Physical Component Summary (PCS) and Mental Component Summary (MCS) derived from the Short-Form 36 (SF-36) health survey in CABG patients.Methods::The study population consisted of 433 patients who underwent isolated elective CABG at Fuwai Hospital between 2012 and 2013. SF-36 assessments were conducted during both the hospitalization period and follow-up. The primary endpoint of the study was all-cause mortality, while the secondary outcome was a composite measure including death, myocardial infarction, stroke, and repeat revascularization. We assessed the relationships between the PCS and MCS at baseline, as well as their changes during the first 6 months after the surgery (referred to as ΔPCS and ΔMCS, respectively), and the observed outcomes.Results::The patients were followed for an average of 6.28 years, during which 35 individuals (35/433, 8.1%) died. After adjusting for clinical variables, it was observed that baseline MCS scores (hazard ratio [HR] for a 1-standard deviation [SD] decrease, 1.57; 95% confidence interval [CI], 1.07–2.30) and ΔMCS (HR for a 1-SD decrease, 1.67; 95% CI, 1.09–2.56) were associated with all-cause mortality. However, baseline PCS scores and ΔPCS did not exhibit a significant relationship with all-cause mortality. Notably, there was a dose-response relationship observed between ΔMCS and the likelihood of all-cause mortality (HRs for the 2nd, 3rd and 4th quartiles compared to the 1st quartile, 0.33, 0.45 and 0.11, respectively).Conclusions::Baseline MCS and changes in MCS were independent predictors for long-term mortality of CABG. Better mental health status and recovery indicated better prognosis.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Background::The potential impact of pre-existing coronary artery stenosis (CAS) on acute pulmonary embolism (PE) episodes remains underexplored. This study aimed to investigate the association between pre-existing CAS and the elevation of high-sensitivity cardiac troponin I (hs-cTnI) levels in patients with PE.Methods::In this multicenter, prospective case-control study, 88 cases and 163 controls matched for age, sex, and study center were enrolled. Cases were patients with PE with elevated hs-cTnI. Controls were patients with PE with normal hs-cTnI. Coronary artery assessment utilized coronary computed tomographic angiography or invasive coronary angiography. CAS was defined as ≥50% stenosis of the lumen diameter in any coronary vessel >2.0 mm in diameter. Conditional logistic regression was used to evaluate the association between CAS and hs-cTnI elevation.Results::The percentage of CAS was higher in the case group compared to the control group (44.3% [39/88] vs. 30.1% [49/163]; P = 0.024). In multivariable conditional logistic regression model 1, CAS (adjusted odds ratio [OR], 2.680; 95% confidence interval [CI], 1.243–5.779), heart rate >75 beats/min (OR, 2.306; 95% CI, 1.056–5.036) and N-terminal pro-B type natriuretic peptide (NT-proBNP) >420 pg/mL (OR, 12.169; 95% CI, 4.792–30.900) were independently associated with elevated hs-cTnI. In model 2, right CAS (OR, 3.615; 95% CI, 1.467–8.909) and NT-proBNP >420 pg/mL (OR, 13.890; 95% CI, 5.288–36.484) were independently associated with elevated hs-cTnI. Conclusions::CAS was independently associated with myocardial injury in patients with PE. Vigilance towards CAS is warranted in patients with PE with elevated cardiac troponin levels.

Aim To investigate the protective effects of curcumin(CUR)on crystal-induced renal injury and its underlying mechanism in the mouse model of neph-rolithiasis.Methods The mouse model of stone for-mation was established via successive intraperitoneal injection of glyoxylate.Proximal tubular epithelial cell line HK-2 treated with calcium oxalate monohydrate(COM)was used as an in vitro model.The protective role of CUR on nephrolithiasis was tested by determina-tion of tubular injury,crystal deposition and adhesion,levels of inflammatory cytokines.In vitro,the effects of CUR on the cell viability and inflammatory factors of HK-2 cells were measured.The proteins in the Toll-like receptor 4(TLR4)/nuclear factor κB(NF-κB)and nuclear factor erythroid 2-related factor 2(NRF2)/hemeoxygenase-1(HO-1)signaling path-ways were measured by Western blot for confirming the relationship between CUR and these pathways.Final-ly,NRF2 inhibitor ML385 and TLR4 activator CCL-34 were respectively used on COM-induced HK-2 cells ex-posed to CUR for the conduction of gain-of-function and loss-of-function assays.Results CUR improves the damage in the mouse model of kidney stone forma-tion,inhibits inflammation and antioxidative effects;promotes the viability of HK-2 cells induced by COM,and inhibits the expression of inflammatory factors.CUR suppresses the expression of proteins in the TLR4/NF-κB pathway,promotes the transfer of NRF2 from the cytoplasm to the nucleus,and enhances the ex-pression of HO-1.ML385 and CCL-34 respectively counteract the anti-inflammatory effects of CUR on COM-induced HK-2 cells.Conclusions Taken togeth-er,our study demonstrates the protective effect of CUR on the deposition of kidney stone and consequent tubu-lar injury.CUR through regulation of the TLR4/NF-κB and NRF2/HO-1 pathways improves renal injury.

Objective To study the anti-reflux effect of conical gastric stump embedding in radical resection of esophageal cancer.Methods A total of 60 patients who planned to undergo radical resection of esophageal cancer in our hospital from June 2020 to June 2022 were selected as the study objects,and the patients were divided into the observation group and the control group by random number table method,with 30 cases in each group.Patients in both groups underwent laparoscopic radical resection of esophageal cancer and esophagogastric end-to-side mechanical anastomosis.The observation group adopted the conical gastric stump embedding technique after esophagogastric end-to-side mechanical anastomosis.The perioperative related indexes,postoperative complications and gastroesophageal reflux of patients in the two groups were compared.The postoperative anti-reflux effect was evaluated by reflux disease questionnaire(RDQ)score and 24-hour intraesophageal pH monitoring.Results The operation time and digestive tract reconstruction time of patients in the observation group were longer than those in the control group(P<0.05),while there was no statistically significant difference in the amount of intraoperative bleeding,the number of lymph node dissection,the first exhaust time,or the postoperative hospital stay of patients between the two groups(P>0.05).There was no statistically significant difference in the overall incidence of postoperative complications between the two groups(P>0.05).The severity of postoperative gastroesophageal reflux of patients in the observation group was lighter than that in the control group,and the difference was statistically significant(P<0.05).The RDQ score,24-hour reflux frequency,>5 minutes reflux frequency,pH<4 time,and longest reflux time of patients in the observation group was significantly lower/less/shorter than those in the control group(P<0.05).Conclusion The conical gastric stump embedding technique is safe and feasible in the radical resection of esophageal cancer.Although the operation time and digestive tract reconstruction time are slightly prolonged,it does not increase the perioperative risks,which can significantly reduce the occurrence and severity of postoperative gastroesophageal reflux of patients,and achieve a good anti-reflux effect.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To conduct scoping review of related researches on application of somatosensory games in frail elderly people, summarize the intervention elements, outcome indicators and adverse events of somatosensory games, so as to provide reference for related research.Methods:Literature on the application of somatosensory games in frail elderly people was searched from PubMed, Web of Science, Cochrane Library, Embase, CNKI, Wanfang Database, VIP database and China Biology Medicine disc, and the search period was from establishment of databases to July 10, 2023. The included literature was summarized and analyzed.Results:A total of 12 articles were included. Somatosensory game interventions were mainly based on existing commercial game equipment. The frequency of intervention was mainly 2 to 3 times a week, the duration was 20 to 60 minutes, and the course of treatment was 3 to 12 weeks. And most interventions had management or supervision mechanisms. Somatosensory games improved physical function and health-related quality of life in frail elderly people to some extent, but had no effect on mental health. Some studies reported fewer or even no adverse events related to somatosensory gaming intervention, and there were few reports on the feasibility and acceptability of the intervention.Conclusions:Somatosensory games have a certain effect on improving the physical function and health-related quality of life of frail elderly people, and there are fewer adverse events. Future research can draw on existing commercial gaming equipment to develop more scientific, practical and personalized somatosensory games, while improving the evaluation indicators and enhancing intervention effect.

Objective To investigate the effects of cultured mycelium Cordyceps sinensis(CMCS)on the AMPK/SirT1 signaling pathway in carbon tetrachloride(CCl4)-induced liver fibrosis in mice.Methods Forty male SPF-grade C57BL/6 mice were divided randomly into a normal control group,CMCS control group(3.0 g/kg),model control group,CMCS1.5 g/kg group,and CMCS 3.0 g/kg group.Mice were injected intraperitoneally with 10%CCl4(2 mL/kg)to induce liver fibrosis.Two weeks later,serum levels of alanine transaminase(ALT),aspartate transaminase(AST),and total bilirubin(TBil)were measured.Inflammation and collagen deposition in liver tissue were observed by hematoxylin and eosin(HE)and Sirius red staining,respectively.The content of hydroxyproline in liver tissue was detected by Jamall's hydrochloric acid hydrolysis method.Levels of interleukin(IL)-6,monocyte chemoattractant protein-1(MCP-1),interferon,tumor necrosis factor(TNF),IL-10,and IL-12p70 in liver tissue were detected using a cytometric bead array analysis system.Collagen Ⅰ and SirT1 expression in liver tissue were detected by immunohisotochemistry,and Prkaa1,Prkaa2,Lkb1,and p53 gene expression were detected by real-time fluorescent quantitative reverse transcriptase-polymerase chain reaction.Results Serum levels of ALT,AST,and TBil were significantly increased in the model control group compared with those in the normal control group(P＜0.05).HE and Sirius red staining showed extensive inflammatory cell infiltration and collagen deposition in the liver,respectively.Hydroxyproline content and expression levels of IL-6,MCP-1,and TNF in the liver were significantly increased(P＜0.05),while IL-10 and IL-12p70 levels were significantly decreased(P＜0.01).Immunohistochemical staining revealed an increase in Collagen Ⅰ expression and SirT1 staining was decreased in the hepatic sinusoidal space,while collagen deposition was increased.Prkaa1,Prkaa2,and Lkb1 gene expression levels were decreased and p53 was increased in liver tissue(P＜0.05).CMCS significantly reduced serum ALT and AST levels,decreased IL-6,MCP-1,and TNF expression in liver tissue(P＜0.05),up-regulated IL-10 and IL-12p70(P＜0.05),alleviated liver inflammation,collagen deposition,and hydroxyproline content,up-regulated the expression of SirT1 in the hepatic sinusoidal space,enhanced Prkaa1,Prkaa2,and Lkb1 expression(P＜0.05),and down-regulated Collagen Ⅰ and p53(P＜0.05)in the liver.Compared with CMCS 1.5 g/kg,CMCS 3.0 g/kg significantly inhibited liver inflammation and collagen deposition and up-regulated AMPK/SirT1 expression(P＜0.05).Conclusions CMCS could improve CCl4-induced liver fibrosis via up-regulation of the AMPK/SirT1 signaling pathway.
