OBJECTIVE: To assess health equity in the Yangtze River region to improve understanding of the correlation between hand, foot, and mouth disease (HFMD) and socioeconomic factors. METHODS: From 2014-2016, data on HFMD incidence, population statistics, economic indicators, and meteorology from 26 cities along the Yangtze River were analyzed. A multi-city random-effects meta-analysis was performed to study the relationship between temperature and HFMD transmission, and health equity was assessed with respect to socio-economic impact. RESULTS: Over the study period, 919,458 HFMD cases were reported, with Shanghai (162,303) having the highest incidence and Tongling (5,513) having the lowest. Males were more commonly affected (male-to-female ratio, 1.49:1). The exposure-response relationship had an M-shaped curve, with two HFMD peaks occurring at 4 °C and 26 °C. The relative risk had two peaks at 1.30 °C (1.834, 95% CI: 1.204-2.794) and 31.4 °C (1.143, 95% CI: 0.901-1.451), forming an M shape, with the first peak higher than the second. The most significant impact of temperature on HFMD was observed between -2 °C and 18.1 °C. The concentration index (0.2463) indicated moderate concentration differences, whereas the Theil index (0.0418) showed low inequality in distribution. CONCLUSION The incidence of HFMD varied across cities, particularly with changes in temperature. Economically prosperous areas showed higher risks, indicating disparities. Targeted interventions in these areas are crucial for mitigating the risk of HFMD.

OBJECTIVE: To investigate the efficacy and safety of oblique lateral interbody fusion(OLIF) channel technique combined with pedicle screw internal fixation in the treatment of single-segment lumbar intervertebral space/vertebral body infection. METHODS: A retrospective analysis was conducted on 23 patients who underwent surgical treatment for lumbar infection from January 2021 to December 2022. The patients were divided into the OLIF channel group and the traditional open surgery group according to the surgical methods. There were 16 cases in the OLIF channel group, including 9 males and 7 females, with an average age of (68.5±12.1) years old;there were 7 cases in the traditional open surgery group, including 4 males and 3 females, with an average age of (75.0±3.2) years old. The operation time, intraoperative blood loss, hospital stay, incision length, visual analogue scale(VAS), activities of daily living (ADL) score, Oswestry disability index (ODI), erythrocyte sedimentation rate(ESR), C-reactive protein(CRP) before and 1 week and 3 months after the operation, and the intervertebral fusion status on the last follow-up CT were compared between the two groups. RESULTS: Compared with the open surgery group, the OLIF channel group had shorter operation time (209.87±31.5) min vs. (246.0±42.7) min, less intraoperative blood loss (225.625±91.1) ml vs. (364.2±74.8) ml, and shorter incision length (6.1±1.2) vs. (14.0±1.4) cm, and the differences were statistically significant(P<0.05). Before and 1 week and 3 months after the operation, the lumbar VAS in the OLIF group were (6.3±0.6), (2.8±0.7), (1.1±0.5), and those in the traditional open surgery group were (6.4±0.6), (3.4±0.5), (1.2±0.3);the ADL scores in the OLIF group were (45.0±4.5), (60.3±4.3), (94.1±4.2), and those in the open group were (46.4±5.6), (60.7±4.5), (92.9±4.9); the ODI scores in the OLIF group were (86.3±2.9)%, (69.5±4.1)%, (23.0±3.2)%, and those in the open group were (87.3±3.8)%, (69.8±4.2)%, (23.8±3.6)%, all of which showed significant improvement(P<0.05). Three months after the operation, CRP, PCT, and ESR were significantly lower than those before the operation, and CRP and PCT returned to normal, while ESR was still slightly elevated in some patients. The last follow-up CT showed that continuous trabecular bone formation was observed between the upper and lower endplates of the surgical segments in all patients, and the fusion time was (8.7±4.5) months. CONCLUSION The OLIF channel technique combined with posterior internal fixation is a minimally invasive and effective treatment method, which can effectively control infection, relieve pain, and improve the quality of life of patients. Compared with traditional open surgery, it has the advantages of minimally invasive, shorter operation time, and less intraoperative blood loss.

BACKGROUND:Degenerative scoliosis is defined as a condition that occurs in adulthood with a coronal cobb angle of the spine>10° accompanied by sagittal deformity and rotational subluxation,which often produces symptoms of spinal cord and nerve compression,such as lumbar pain,lower limb pain,numbness,weakness,and neurogenic claudication.The finite element method is a mechanical analysis technique for computer modelling,which can be used for spinal mechanics research by building digital models that can realistically restore the human spine model and design modifications. OBJECTIVE:To review the application of finite element method in the etiology and treatment of degenerative scoliosis. METHODS:The literature databases CNKI,PubMed,and Web of Science were searched for articles on the application of finite element method in degenerative scoliosis published before October 2023.Search terms were"finite element analysis,biomechanics,stress analysis,degenerative scoliosis,adult spinal deformity"in Chinese and English.Fifty-four papers were finally included. RESULTS AND CONCLUSION:(1)The biomechanical findings from the degenerative scoliosis model constructed using the finite element method were identical to those from the in vivo experimental studies,which proves that the finite element method has a high practical value in degenerative scoliosis.(2)The study of the etiology and treatment of degenerative scoliosis by the finite element method is conducive to the prevention of the occurrence of the scoliosis,slowing down the progress of the scoliosis,the development of a more appropriate treatment plan,the reduction of complications,and the promotion of the patients'surgical operation.(3)The finite element method has gradually evolved from a single bony structure to the inclusion of soft tissues such as muscle ligaments,and the small sample content is increasingly unable to meet the research needs.(4)The finite element method has much room for exploration in degenerative scoliosis.

Objective To explore and verify the active components of Dachengqi decoction in regulating autophagy and its mechanism of protecting the intestinal mucosal barrier through network pharmacology and animal experiments.Methods The chemical components and autophagy-related target points of Dachengqi decoction were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database Analysis Platform(TCMSP)and GeneCards databases.The intersection of the drug target points and disease target points was taken and analyzed.The Cytoscape 3.10.2 software's Network Analyzer tool was used to analyze the drug components and target points,and the core target points were screened out to construct a traditional Chinese medicine compound regulatory network.The drug active component target point-disease network model and protein-protein interaction(PPI)network were visualized.Then,30 C57BL/6J mice were randomly divided into the Dachengqi decoction group,the intestinal infection group,and the control group,with 10 mice in each group.The intestinal infection group was given 200 μL/d of Klebsiella pneumoniae strain by gavage for 5 consecutive days,with a colony count of 109 CFU/mL,to create an intestinal infection model.The control group was given 200 μL/d of sterile normal saline by gavage.The Dachengqi decoction group(drug composition:Rhubarb 12 g,Aurantii Fructus 12 g,Magnolia Officinalis 24 g,Mirabilite 9 g,the drugs were dissolved in boiling distilled water to make a 1 kg/L solution)was given by gavage at a dose of 8 g·kg-1·d-1 for 3 consecutive days,and then given Klebsiella pneumoniae by gavage for 5 consecutive days on the 4th day.Detection indicators and methods:after the experiment,the mice were sacrificed and the terminal ileum tissues were collected.The tissues were stained with hematoxylin-eosin(HE),and the pathological changes of the intestinal mucosa were observed under a light microscope;immunofluorescence staining was used to observe the positive expressions of junction proteins ZO-1,Claudin-2,light chain 3-Ⅱ(LC3-Ⅱ),and Beclin-1 and the intestinal mucosal autophagy;the mRNA expression levels of autophagy genes were determined by polymerase chain reaction(PCR).Results The intersection of the obtained drug targets and disease targets yielded 111 potential autophagy-related targets for drug treatment of diseases.Key targets included β2-adrenergic receptor(ADRB2),heme oxygenase-1(HO-1),etc.,and the signaling pathways involved included AMP-activated protein kinase(AMPK)pathway,mammalian target of rapamycin(mTOR)pathway,etc.Animal experiments confirmed that the intestinal mucosal barrier function in the Dachengqi decoction group was better than that in the intestinal infection group,and the positive expression of microtubule-associated protein 1 lingt chain 3-Ⅱ(LC3-Ⅱ)and autophagy gene Beclin1 was significantly higher than that in the intestinal infection group.Transcriptome sequencing results showed that the key genes associated with autophagy and oxidative stress included ADRB2,HO-1,etc.The mRNA expression levels of ADRB2 and HO-1 in the Dachengqi decoction group were significantly higher than those in the intestinal infection group[HO-1 mRNA expression(FPKM):11.20±0.80 vs.6.63±0.53,ADRB2 mRNA expression(FPKM):6.98±0.54 vs.3.98±0.32,both P<0.01],verifying some of the predictions from network pharmacology.Conclusions Dachengqi decoction regulates autophagy through multiple components,multiple targets and multiple pathways,protecting the intestinal mucosal barrier function and reducing the translocation of intestinal microbiota.This lays a certain foundation for further in-depth research on the mechanism of reducing intestinal bacterial translocation by Dachengqi decoction.

Objective:To evaluate the early outcomes of total hip arthroplasty (THA) and discuss the revisions post THA in the treatment for Kashin-Beck disease (KBD) with severe hip problems.Methods:This retrospective cohort study enrolled 50 patients (64 hips) with a mean age of 52.4±8.7 years, including 25 male patients and 25 female patients (36 left hips and 28 right hips), who were diagnosed as KBD with hip problems and received THA at Arthritis Clinical and Research Centre, Peking University People's Hospital from October 2019 to January 2024. The leg length discrepancy (LLD), femoral offset (FO), abduction angle and anteversion angle were calculated preoperatively and one week post-operation. The postoperative radiological indexes and the functional outcomes in the last follow-up were compared with the preoperative assessment.Results:The surgical duration was 105(80, 120) min and the bleeding amount was 300(200, 400) ml. All the cases were followed up for an average of 37 months (ranging from 21 to 44 months). Significant differences were found on postoperative radiological images, with LLD improving to 0.50±0.78 cm from a preoperative value of -1.36±0.79 cm, and FO increasing to 3.28±1.01 cm from 2.72±0.83 cm ( P<0.05). The mean postoperative abduction angle and anteversion angle were 42.5°±7.7° and 15.1°±5.9°, respectively. A total of 71.8% and 95.3% hips fell within the Lewinnek safe zones of abduction angle and anteversion angle, respectively. In terms of functional outcomes, the average range of motion improved significantly to 185°(173°, 210°) from a preoperative value of 99°(76°, 123°), and the Harris Hip Score increased from 35(26, 43) preoperatively to 70(63, 80) postoperatively ( P<0.05). During the follow-up, there were complications for two cases of femoral stem loosening, one case of periprosthetic femoral fracture, one case of hip dislocation, and one case of acetabular component loosening with hip subluxation. Additionally, seven patients exhibited Trendelenburg gait. A total of five hips required revision surgery due to severe complications, including two cases of femoral stem loosening, one case of periprosthetic femoral fracture, one case of hip dislocation, and one case of acetabular component loosening with subluxation. Conclusions:Patients with KBD demonstrated significant early improvements in both radiological and functional outcomes following THA.

Objective:To explore the predictive role of dynamic changes in serum Golgi protein 73 (GP73) and its inflammatory influencing factors on the reversal of hepatitis B virus-related liver fibrosis.Methods:Two hundred and seventy-eight patients with hepatitis B virus-related liver fibrosis who received entecavir or combined Fuzheng Huayu tablets treatment and completed two liver biopsies (biopsy) in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from September 2014 to July 2019 were selected. The correlation between serum GP73 level and fibrosis stage (Ishak) and inflammation grade (HAI) was analyzed. The patients were divided into a fibrosis reversal group (Ishak decreased≥1 point) and a non-reversal group (Ishak score remained unchanged or increased), and an inflammation improvement group (ΔHAI≤-2) and a non-improvement group (ΔHAI>-2) according to the pathological changes of liver tissue before and after treatment. The cross-sectional value of GP73, its change value (ΔGP73), and the role of inflammatory influencing factors on the liver before and after treatment were evaluated for their predictive efficacy regarding liver fibrosis regression. The receiver operating characteristic curve was used to explore the predictive value of serum ΔGP73 combined with liver stiffness change value (ΔLSM) for the reversal of hepatitis B virus-related liver fibrosis. One-way analysis of variance was used to compare the data between the groups of quantitative data, and a paired t-test or rank sum test was used for the data before and after treatment. The χ2 test was used to compare the differences between the groups of enumeration data. Spearman and Pearson correlation methods were used for correlation analysis. Results:The serum GP73 level was higher in the cirrhosis group than that in the group without significant fibrosis ( P<0.01). The GP73 level was higher in patients with moderate and severe inflammation than that in the mild group ( P<0.05). Pre-treatment serum GP73 was positively correlated with fibrosis stage ( r=0.248), inflammation grade ( r=0.318), and alanine aminotransferase level ( r=0.203) ( P<0.01). The area under the receiver operating characteristic curve (AUROC) for the predictive ability of post-treatment GP73 levels in the fibrosis reversal was 0.633 (95% CI: 0.573-0.689, sensitivity 62.68%, and specificity 59.56%). The decrease in ΔGP73 was significantly higher in the liver fibrosis reversal group ( n=142) than that in the non-reversal group ( n=136) [-39.22(-85.08,-14.31) ng/mL vs. -30.06(-61.29,-5.84) ng/mL, P<0.01]. ΔGP73 was also associated with liver inflammation changes (AUROC=0.634, 95% CI: 0.574-0.690, sensitivity of 51.64%, specificity of 69.87%). Additionally, the predictive effectiveness of GP73 for fibrosis reversal improved after normalization of serum ALT (AUROC: 0.651 vs. 0.522 at baseline). ΔGP73 combined with ΔLSM had improved the AUROC predictive effectiveness from single indicators of 0.609 (ΔGP73) and 0.656 (ΔLSM) to 0.800 (95% CI: 0.662-0.899), with specificity increasing from 72.22% to 86.11%. Conclusion:Serum GP73 level is positively correlated with the degree of liver fibrosis and inflammation. Serum GP73 levels and ΔGP73 can predict the reversal of fibrosis, with liver inflammation being an important influencing factor following treatment. ΔGP73 combined with ΔLSM can significantly optimize the evaluation efficiency of liver fibrosis reversal.

Objective To investigate the diagnostic value of 4 novel inflammatory markers related to routine blood tests,namely neutrophil-to-lymphocyte ratio(NLR),red blood cell distribution width(RDW),hemoglobin-to-RDW ratio(HRR)and systemic immune-inflammation index(SII),in elderly patients with chronic cardiovascular disease(CVD)complicated with frailty.Methods Retrospectively analyze 110 patients with chronic stable CVD who were hospitalized in the cadre ward of cardiovascular medicine at the Air Force Characteristic Medical Center from January 2022 to June 2023.According to the assessment results of the Fried scale,they were divided into three groups:non-frailty group(Fried score=0,n=30),the pre-frailty group(Fried score 1 or 2,n=40)and frailty group(Fried score≥3,n=40).The differences in general information,the impairment rate of daily living activities,miniature nutritional assessment-short form(MNA-SF)scores,mini-mental state examination(MMSE)scores,and the indicators such as NLR,RDW,HRR,and SII among the three groups were compared.Spearman rank correlation was used to analyze the correlation between NLR,RDW,HRR,SII and frailty scores as well as each frailty indicator.Multivariate logistic regression analysis was performed to identify the independent risk factors for frailty in elderly patients with chronic CVD,and the receiver operating characteristic(ROC)curve was used to assess the clinical diagnostic value of NLR and HRR in elderly patients with chronic CVD complicated with frailty.Results Compared with non-frailty group and pre-frailty group,patients in frailty group were older,with higher impaired rates of daily living activities,NLR,RDW,and SII,and lower MNA-SF scores,MMSE scores,and HRR,and differences were statistically significant(P<0.05).Spearman rank correlation analysis showed that the frailty score was positively correlated with NLR(rs=0.354,P<0.001),and RDW(rs=0.448,P<0.001),negatively correlated with HRR(rs=-0.232,P=0.024),and had no significant correlation with SII(rs=0.144,P=0.167).Further analysis of the correlation between the above novel inflammatory markers and the 5 components of frailty showed that NLR was positively correlated with fatigue(rs=0.228,P=0.017),slowed walking speed(rs=0.299,P<0.001),and low physical function(rs=0.319,P<0.001);RDW was positively correlated with decreased grip strength(rs=0.321,P<0.001),slowed walking speed(rs=0.422,P<0.001),and low physical function(rs=0.246,P=0.001);and HRR was negatively correlated with slowed walking speed(rs=-0.230,P=0.025),and low physical function(rs=-0.299,P=0.003).Multivariate logistic regression analysis showed that MNA-SF score(OR=0.577,95%CI 0.342-0.973)was an independent protective factor for pre-frailty in elderly patients with chronic CVD(P<0.05);NLR(OR=7.866,95%CI 1.101-56.185)was an independent risk factor for frailty,while HRR(OR=0.344,95%CI 0.120-0.983)and MNA-SF score(OR=0.292,95%CI 0.146-0.580)were independent protective factors for frailty in elderly CVD patients(P<0.05).The area under the ROC curve of NLR and HRR for diagnosing frailty in elderly patients with chronic CVD were 0.778 and 0.749,respectively.Conclusion NLR and HRR have high clinical diagnostic value for frailty in elderly patients with chronic CVD,and are expected to become effective inflammatory markers for screening elderly patients with chronic CVD complicated with frailty.

Objective To evaluate the changes in postoperative plasma β-endorphin(β-EP)levels in patients who had received perioperative electroacupuncture(EA)treatment in 10 randomized controlled trials(RCTs)and examine the impact of EA on postoperative pain.Methods This meta-analysis evaluated the changes in plasma β-EP levels and visual analog scale(VAS)12,24 and 48 hours after surgery in patients receiving perioperative EA.It also assessed the changes in plasma serotonin(5-hydroxytryptamine,5-HT)and prostaglandin E2(PGE2)levels at 24 hours postsurgery.A comprehensive search was conducted in the China National Knowledge Infrastructure(CNKI),Wanfang,Chongqing VIP database,Chinese Biomedical Database(CBM),Web of Science,and PubMed databases.RCTs on perioperative EA and β-EP published from the inception of the websites up to July 25,2023,were retrieved.Effect size aggregation,literature quality assessment,and bias analysis were performed using RevMan 5.3 software,and sensitivity analysis was conducted via R 4.3.1.Results A total of 10 RCTs involving 706 patients were included.EA in conjunction with conventional anesthesia significantly increased plasma β-EP levels at 12 hours postsurgery[standard mean difference(SMD)=2.79,95%CI(1.85,3.72),Z=5.81,P＜0.00001],24hours postsurgery[SMD=1.87,95%CI(0.9,2.83),Z=3.79,P=0.0001],and 48 hours postsurgery[SMD=2.02,95%CI(1.49,2.54),Z=7.50,P＜0.00001].EA reduced plasma PGE2 levels at 24 hours postsurgery and plasma 5-HT levels at 24 hours postsurgery,and the VAS at 12,24 and 48 hours after surgery also decreased.Conclusion These findings suggest that perioperative EA markedly elevates plasma β-EP levels,reduces pain-inducing factors in plasma,and effectively alleviates acute postoperative pain.

Objective To evaluate the clinical value of bedside ultrasonographic measurement of optic nerve sheath diameter(ONSD)combined with serum matrix metalloproteinase-9(MMP-9)and neutrophil-to-lymphocyte ratio(NLR)in assessing postoperative intracranial hypertension in patients with severe traumatic brain injury.Methods A total of 100 patients with severe traumatic brain injury were enrolled as study subjects.According to postoperative intracranial pressure status,the patients were divided into normal group(n=33)and elevated group(n=67).ONSD,MMP-9 and NLR lev-els were compared between the two groups.The correlations among ONSD,serum MMP-9 and NLR in the elevated group were analyzed.The influencing factors of postoperative intracranial hypertension in patients with severe traumatic brain injury were evaluated.Receiver operating characteristic(ROC)curve analysis was performed to assess the diagnostic value of ONSD combined with serum MMP-9 and NLR for postoperative intracranial hypertension.Results ONSD,serum MMP-9 and NLR levels were significantly higher in the elevated group than those in the normal group(P＜0.05).ONSD was positively correlated with MMP-9(r=0.367,P=0.002),ONSD was positively correlated with NLR(r=0.419,P＜0.01),and MMP-9 was positively correlated with NLR(r=0.324,P=0.007).Elevated ONSD,serum MMP-9 and NLR were risk factors for increased in-tracranial pressure after severe craniocerebral injury surgery(P＜0.05).The area under the curve for evaluation of postoperative intracranial pressure increase in patients with severe craniocerebral in-jury by combination of ONSD,serum MMP-9 and NLR was 0.976(95％CI,0.952 to 1.000),the sensitivity was 91.04％,and the specificity was 93.94％.The combined evaluation value of ONSD,serum MMP-9 and NLR for increased intracranial pressure after surgery in patients with severe craniocerebral injury was higher(Zcombined with-ONSD=3.453,P=0.001,Zcombined with-MMP-9=3.637,P＜0.001,Zcombined with-NLR=2.654,P=0.008).Conclusion In patients with increased intracra-nial pressure after severe craniocerebral injury surgery,their levels of ONSD,serum MMP-9 and NLR increase,and the increase of the three indicators will increase the risk of increased intracranial pressure after surgery.The combined detection of the three indicators has certain value in evaluating the increase of intracranial pressure in patients after surgery.

Objective:To evaluate the clinical efficacy of transoral robotic surgery (TORS) in the treatment of malignant tongue base tumors.Methods:A multicenter study was conducted to collect and analyze the clinical data of patients with malignant tongue base tumors who underwent TORS at five otolaryngology-head and neck surgery centers in China, including Eye Ear Nose and Throat Hospital of Fudan University, Sun Yat-sen University Cancer Center, Tongji Hospital of Huazhong University of Science and Technology, Sun Yat-sen Memorial Hospital of Sun Yat-sen University, and the First Affiliated Hospital of China Medical University between January 2017 and January 2023. Among the patients, 38 were males and 11 were females, with a mean age of 59.0±8.8 years. Baseline characteristics, complications, and follow-up data were compared between groups. Independent sample t-tests or Mann-Whitney U tests was used for comparisons of continuous variables; chi-square tests or Fisher′s exact tests was applied for categorical variables. Survival analysis was performed using the Kaplan-Meier method to calculate overall survival and disease-free survival, and differences between groups were compared using the log-rank test. Results:Among the 49 patients, 41 (83.7%) were diagnosed with squamous cell carcinoma (SCC), with a p16 positive rate of 51.2% (21/41). There were no statistically significant differences between the p16-positive group ( n=21) and the p16-negative group ( n=20) in age, sex, or postoperative bleeding (all P>0.05). However, there was a significant difference in TNM stage between the two groups ( χ2=14.556, P=0.020), with the p16-positive group predominantly in stage I (66.7%) and the p16-negative group primarily in stages Ⅲ and Ⅳ (40.0% and 30.0%, respectively). The postoperative tracheotomy rate was 30.6% (15/49), and the incidence of postoperative bleeding was 6.1% (3/49). The 1-year and 3-year overall survival rates were 98.0% and 92.5%, respectively, while, the 1-year and 3-year disease-free survival rates were 89.2% and 84.9%, respectively. No significant differences were observed between the p16-positive and p16-negative groups in 3-year overall survival (100% vs. 83.8%, χ2=1.093, P=0.518) or 3-year disease-free survival (68.2% vs. 88.9%, χ2=2.161, P=0.382). Conclusion:TORS for malignant tongue base tumors demonstrates high clinical safety and favorable oncological outcomes.
