Neuropathic pain, often featuring allodynia, imposes significant physical and psychological burdens on patients, with limited treatments due to unclear central mechanisms. Addressing this challenge remains a crucial unsolved issue in pain medicine. Our previous study, using protein kinase C gamma (PKCγ)-tdTomato mice, highlights the spinal feedforward inhibitory circuit involving PKCγ neurons in gating neuropathic allodynia. However, the regulatory mechanisms governing this circuit necessitate further elucidation. We used diverse transgenic mice and advanced techniques to uncover the regulatory role of the descending serotonin (5-HT) facilitation system on spinal PKCγ neurons. Our findings revealed that 5-HT neurons from the rostral ventromedial medulla hyperpolarize spinal inhibitory interneurons via 5-HT_2C receptors, disinhibiting the feedforward inhibitory circuit involving PKCγ neurons and exacerbating allodynia. Inhibiting spinal 5-HT_2C receptors restored the feedforward inhibitory circuit, effectively preventing neuropathic allodynia. These insights offer promising therapeutic targets for neuropathic allodynia management, emphasizing the potential of spinal 5-HT_2C receptors as a novel avenue for intervention.

Objective:This study aimed to explore the clinical value of myostatin(MST) and follistatin(FST) as biological biomarkers in evaluating sarcopenia in elderly women.Methods:This was a retrospective cross-sectional study that enrolled 350 females aged 20-89 years who underwent physical examinations in Shanghai Huadong Hospital in 2021. Demographic characteristics, muscle mass, fat mass, bone mineral density, hand grip strength, gait speed, and serum indices of MST and FST were collected.Results:The serum levels of MST did not change significantly with age. However, the serum levels of FST increased with age. In women aged≥60 years, MST was positively correlated with total lean mass and appendicular skeletal muscle index(ASMI; r=0.236, P=0.041; r=0.289, P=0.014), while FST was negatively correlated with ASMI( r=-0.265, P=0.030). In multivariate stepwise regression analysis, after adjusting for age, body mass index, hip bone mineral density, and total fat mass, only FST was independently correlated with ASMI( β=-0.238, P=0.006), while MST was not correlated with ASMI. The receiver operating characteristic curve was plotted using muscle mass reduction as the state variable and serum FST level as the test variable. The area under the curve was 0.753. And when the FST cutoff value was 17.49 ng/mL, the maximum Jordan index was 0.46, with a sensitivity of 77.3% and a specificity of 68.7%. Women aged ≥60 years were divided into three groups based on serum FST levels. Compared to the upper third of the serum FST level group, the low third of the FST level group had a significantly reduced risk of suffering from sarcopenia( OR=0.098, P =0.036). Conclusions:Serum FST lever has a better correlation with muscle mass among elderly women, making it a promising biomarker for evaluating muscle mass.

Objective:To explore the correlation of early urinary continence(UC)after laparoscopic radical prostatectomy(LRP)with relevant preoperative MRI parameters of the urinary tract structure and provide some theoretical evidence for screening the high-risk population with postoperative urinary incontinence.Methods:This study included 49 PCa patients aged 50-78 years trea-ted by LRP in Beijing Tongren Hospital from January 2015 to February 2021,and all followed up for 12 months.We collected the com-plete baseline data on the patients,the clinical data possibly related to early postoperative UC,the MRI anatomical parameters associat-ed with UC,and the data on the recovery of early postoperative UC.We recorded the number of urinary pads used,submitted the data obtained to SPSS 23.0 statistical analysis,and identified the possible relevant factors by univariate correlation analysis,followed by R40.3 or SPSS 23.0 multivariate logistic regression analysis of the included factors and the results of UC.Results:MRI images mani-fested that the prostate anteroposterior diameter averaged(4.0±1.11)cm,the transverse diameter(4.6±0.83)cm,the cephalo-caudal diameter 2.4-6.4 cm,the membranous urethral length(MUL)(13.16±3.52)mm,and the thickness of the urethral rhab-dosphincter(URS)1.08-4.37 mm.Multivariate analysis showed that age was significantly correlated with the recovery of UC at 1 month after LRP(P=0.035,OR=0.16),and so was the URS thickness at 3 months(P=0.011,OR=0.02),9 months(P=0.014,OR=0.039)and 12 months(P=0.014,OR=0.039).Urinary incontinence with the URS thickness ≤1.6 mm at 12 months after operation was found of a high severity(P=0.010,OR[95％CI]=0.858-6.240).The MUL was positively correla-ted with the recovery of UC at 9 months(P=0.024,OR=0.508)and 12 months(P=0.024,OR=0.508)postoperatively.Correlation analysis revealed that the prostate volume,prostate diameter and other factors included in this study were not significantly correlated to postoperative UC.Conclusion:The thickness of the URS is positively correlated with the recovery of early UC,the thinner the URS,the severer the UC,and so is MUL.Age is an independent risk factor for the recovery of UC at 1 month after LRP.These findings need to be further verified by more prospective studies with long-term follow-ups.

Objective:To identify the key genes involved in the development and progression of prostate cancer(PCa)and those associated with the prognosis of the malignancy.Methods:We obtained the single-cell sequencing data on 4 cases of PCa from the GSE156632 database.Using R language and the Seurat package,we performed cell clustering and annotation,selected the subpop-ulations of epithelial cells for differential analysis after quality control and cell type identification,and conducted enrichment analysis of the identified differential genes using the Hiplot website.Then we downloaded the single nucleotide polymorphism(SNP)loci corre-sponding to the expression quantitative trait loci(eQTL)of these genes from the UK Biobank(UKB)database,and the clinical data and corresponding gene expression data on PCa patients from The Cancer Genome Atlas(TCGA)and Gene Expression Omnibus(GEO),followed by univariate COX regression analysis of the impact of the genes on the prognosis of the patients after Mendelian ran-domization.Results:A total of 1 566 genes were identified and subjected to enrichment analysis,which indicated that the differenti-al genes might be enriched in the Ras,apoptosis and oxidative phosphorylation signaling pathways.Subsequent Mendelian randomiza-tion revealed 74 potential causal genes among the 1 566 genes,and univariate COX regression analysis of the 74 genes identified 4 pos-sibly related genes FAM3B,JUNB,TMEM59,and KRT5.Comparison of the results of Mendelian randomization and univariate COX regression showed that KRT5 might be the most important gene influencing PCa.Conclusion:FAM3B,JUNB,TMEM59 and KRT5 may play a role in the progression of PCa,and KRT5 may potentially serve as a prognostic predictor and therapeutic target for the malig-nancy.

Objective To investigate the relationship between serum lipid profiles and colorectal adenomas,and to benefit the prevention of colorectal cancer.Methods This study retrospectively analyzes the serum lipid profiles and clinical parameters of 2,960 patients who were diagnosed with colorectal adenomas,and 3,156 individuals without colorectal adenomas in Meizhou People's Hospital from May 2018 to May 2020.The association between serum lipid profiles and colorectal adenoma was evaluated by Logistic regression analysis.Results It was observed that the serum levels of total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C)and apoliprotein B(ApoB)were significantly elevated in patients with colorectal adenomas.Dyslipidemia was more prevalent in adenoma cases than in controls.The Logistic regression analysis suggested that serum TC and TG levels were positively associated with the occurrence of colorectal adenomas.Conclusion Elevated serum TG and TC levels are independent risk factors for adenoma,and adenoma patients with elevated serum TG and TC levels may be more likely to develop high-risk adenoma.

ObjectiveTo describe the epidemic characteristics of COVID-19 after policy adjustment from “Category B notifiable disease with category A management” to “Category B notifiable disease with category B management”， and to explore the protective effect of previous infection with SARS-CoV-2 on common symptoms of reinfection. MethodsHealthcare workers infected with SARS-CoV-2 in a grade A tertiary hospital in Shanghai were included in the study from December 4， 2022 to January 11， 2023. Data on demographic characteristics， clinical symptoms， medical history， and COVID-19 vaccination history were collected. We determined the epidemiological curve and characteristics， and then compared the difference in the severity of clinical symptoms between primary and reinfection subjects.

The average age of these healthcare workers was （34.9±9.1） years old. The number of cases with mild/moderate illness， asymptomatic infection， fever， headache， dry cough， expectoration， and chest tightness were 2 704 （100.0%）， 92 （3.4%）， 2 385 （88.2%）， 2 066 （76.4%）， 1 642 （60.7%）， 1 807 （66.8%）， and 439 （16.2%）， respectively. Reinfection was a protective factor for fever （OR=0.161， P<0.001）， headache （OR=0.320， P<0.001）， and peak body temperature （β=-0.446， P<0.001）. ConclusionFollowing the COVID-19 policy adjustment as a category B notifiable disease， healthcare workers at a grade A tertiary hospital in Shanghai predominantly experiences mild to moderate COVID-19 symptoms. Reinfection results in milder clinical manifestations， with a lower proportion of being asymptomatic.

Objective To summarize the clinical experience of the treatment for complex aortic coarctation with extra anatomic bypass and anatomic correction techniques. Methods The clinical data of patients with complex aortic coarctation treated in the First Affiliated Hospital of Nanjing Medical University and Friendship Hospital of Ili Kazakh Autonomous Prefecture between April 2012 and November 2020 were retrospectively reviewed. Results A total of 12 patients were enrolled, including 5 males and 7 females aged 11-54 (34.3±16.2) years. Extra anatomic bypass grafting was performed in 8 patients and anatomic correction was performed in 4 patients. The operations were successful in all patients. There was no perioperative death. The average cardiopulmonary bypass time was 203.0±46.0 min (7 median incision patients), and the average intraoperative blood loss was 665.0±102.0 mL. The average postoperative ventilator support time was 32.3±7.5 h, and the average postoperative hospital stay time was 10.2±4.3 d. The mean drainage volume of median incision was 1 580.0±360.0 mL, and the mean drainage time was 9.3±2.7 d. The mean drainage volume of left thoracotomy was 890.0±235.0 mL, and the mean drainage time was 4.8±2.5 d. One patient had a transient hoarse after operation and recovered 6 months later. The follow-up period ranged from 2 to 10 years with an average time of 81.0±27.0 months. All patients had a recovery of hypertension, cardiac afterload after 2 years postoperatively. One patient who received an artificial blood vessel replacement in situ was examined stenosis recurrence at the third year after discharge. Others were asymptomatic during the follow-up period. There were no death or other complications. Conclusion The treatment strategy for complex aortic coarctation should be individualized according to the anatomical features and concomitant heart diseases. Extra anatomic bypass technique is a safe and feasible choice.

Injury of the posterior pelvic ring can easily be caused by high-energy impact,and sacroiliac joint dislocation is the most common.The sacroiliac joint,as the hub of load transfer between the trunk and lower extremities,is essential to maintain the stability of the posterior pelvic ring,and once dislocation occurs,restoring the stability of the posterior pelvic ring by timely surgery is necessary.The current surgical approaches for the internal fixation of sacroiliac joint are mainly divided into anterior approach and posterior approach.The choice of the surgical approach directly affects the exposure of the surgical field,the stability of internal fixation and the prognosis of patients;therefore,it is particularly important to select the appropriate surgical approach and fixation method.In this paper,we briefly review the selection of sacroiliac joint fixation points,surgical approaches and postoperative complications.
