Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a complex disease that is often accompanied by mental health disorders. However, the potential mechanisms underlying the heterogeneous clinical presentation of CP/CPPS remain uncertain. This study analyzed widely targeted metabolomic data of expressed prostatic secretions (EPS) and plasma to reveal the underlying pathological mechanisms of CP/CPPS. A total of 24 CP/CPPS patients from The Second Nanning People's Hospital (Nanning, China), and 35 asymptomatic control individuals from First Affiliated Hospital of Guangxi Medical University (Nanning, China) were enrolled. The indicators related to CP/CPPS and psychiatric symptoms were recorded. Differential analysis, coexpression network analysis, and correlation analysis were performed to identify metabolites that were specifically altered in patients and associated with various phenotypes of CP/CPPS. The crucial links between EPS and plasma were further investigated. The metabolomic data of EPS from CP/CPPS patients were significantly different from those from control individuals. Pathway analysis revealed dysregulation of amino acid metabolism, lipid metabolism, and the citrate cycle in EPS. The tryptophan metabolic pathway was found to be the most significantly altered pathway associated with distinct CP/CPPS phenotypes. Moreover, the dysregulation of tryptophan and tyrosine metabolism and elevation of oxidative stress-related metabolites in plasma were found to effectively elucidate the development of depression in CP/CPPS. Overall, metabolomic alterations in the EPS and plasma of patients were primarily associated with oxidative damage, energy metabolism abnormalities, neurological impairment, and immune dysregulation. These alterations may be associated with chronic pain, voiding symptoms, reduced fertility, and depression in CP/CPPS. This study provides a local-global perspective for understanding the pathological mechanisms of CP/CPPS and offers potential diagnostic and therapeutic targets.

Dry eye disease (DED) is a prevalent and intractable ocular disease induced by a variety of causes. Elevated sphingomyelin (SM) levels and pro-inflammatory cytokines were detected on the ocular surface of DED patients, particularly in the meibomian glands. Sphingomyelin synthase 2 (SMS2), one of the proteins involved in SM synthesis, would light a novel way of developing a DED therapy strategy. Herein, we report the design and optimization of a series of novel thiophene carboxamide derivatives to afford 14l with an improved highly potent inhibitory activity on SM synthesis (IC_{50, SMS2} = 28 nmol/L). Moreover, 14l exhibited a notable protective effect of anti-inflammation and anti-apoptosis on human corneal epithelial cells (HCEC) under TNF-α-hyperosmotic stress conditions in vitro, with an acceptable ocular specific distribution (corneas and meibomian glands) and pharmacokinetics (PK) profiles (t _{1/2, cornea} = 1.11 h; t _{1/2, meibomian glands} = 4.32 h) in rats. Furthermore, 14l alleviated the dry eye symptoms including corneal fluorescein staining scores and tear secretion in a dose-dependent manner in mice. Mechanically, 14l reduced the mRNA expression of Tnf-α, Il-1β and Mmp-9 in corneas, as well as the proportion of very long chain SM in meibomian glands. Our findings provide a new strategy for DED therapy based on selective SMS2 inhibitors.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength. Methods We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.Results In the multimetal linear regression, Cu (β=-2.119), As (β=-1.318), Sr (β=-2.480), Ba (β=0.781), Fe (β= 1.130) and Mn (β=-0.404) were significantly correlated with grip strength (P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95％ confidence interval:-1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn (Pinteractions of 0.003 and 0.018, respectively).Conclusion In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

Purpose::Traumatic brain injury (TBI), currently a major global public health problem, imposes a significant economic burden on society and families. We aimed to quantify and predict the incidence and severity of TBI by analyzing its incidence, prevalence, and years lived with disability (YLDs). The epidemiological changes in TBI from 1990 to 2019 were described and updated to provide a reference for developing prevention, treatment, and incidence-reducing measures for TBI.Methods::A secondary analysis was performed on the incidence, prevalence, and YLDs of TBI by sex, age group, and region ( n =21,204 countries and territories) between 1990 and 2019 using the Global Burden of Diseases, Injuries, and Risk Factors Study 2019. Proportions in the age-standardized incidence rate due to underlying causes of TBI and proportions of minor and moderate or severe TBI were also reported. Results::In 2019, there were 27.16 million (95% uncertainty intervals ( UI): 23.36 -31.42) new cases of TBI worldwide, with age-standardized incidence and prevalence rates of 346 per 100,000 population (95% UI: 298 -401) and 599 per 100,000 population (95% UI: 573 -627), respectively. From 1990 to 2019, there were no significant trends in global age-standardized incidence (estimated annual percentage changes: -0.11%, 95% UI: -0.18% --0.04%) or prevalence (estimated annual percentage changes: 0.01%, 95% UI: -0.04% -0.06%). TBI caused 7.08 million (95% UI: 5.00 -9.59) YLDs in 2019, with age-standardized rates of 86.5 per 100,000 population (95% UI: 61.1 -117.2). In 2019, the countries with higher incidence rates were mainly distributed in Central Europe, Eastern Europe, and Australia. The 2019 global age-standardized incidence rate was higher in males than in females. The 2019 global incidence of moderate and severe TBI was 182.7 per 100,000 population, accounting for 52.8% of all TBI, with falls and road traffic injuries being the main causes in most regions. Conclusions::The incidence of moderate and severe TBI was slightly higher in 2019, and TBI still accounts for a significant portion of the global injury burden. The likelihood of moderate to severe TBI and the trend of major injury under each injury cause from 1990 to 2019 and the characteristics of injury mechanisms in each age group are presented, providing a basis for further research on injury causes in each age group and the future establishment of corresponding policies and protective measures.

Objective To construct a prediction model of postoperative poor anastomotic healing in colorectal patients based on LASS0 variable selection,and analyze the prediction efficiency of this model for anastomotic prognosis.Methods 215 patients with colorectal cancer who were treated in our hospital from March 2018 to January 2023 were prospectively included as the research object.All patients underwent laparoscopic radical resection of colorectal cancer,and all patients were followed up for 30 days after operation.They were divided into the poor healing group(24 cases)and the good healing group(191 cases)according to whether there was anastomotic malunion.The general data and clinical data of all patients were collected,and the characteristic factors with non-zero coefficient were screened by using LASSO regression model.Lasso-Logistics regression model was constructed to analyze the related factors leading to poor anastomosis healing,and the receiver operating characteristic curve(ROC)was drawn to calculate the area under receiver operating characteristic curve curve(AUC),sensitivity and specificity.Bootdtrap method was used to carry out 500 repeated sampling for verification.Results The number of male cases in poor healing group was significantly higher than that in good healing group.The levels of white blood cell WBC and C-reactive protein CRP in poor healing group were higher than those in good healing group(P＜0.05).The operation time in the group with poor healing was longer than that in the group with good healing,the tumor diameter was more than 4 cm,the distance between the lower edge of the tumor and the perianal region was less than ≤ 7 cm,there were neoadjuvant chemotherapy before operation,and the number of patients with Ⅲ-Ⅳ was significantly higher than that in the group with good healing(P＜0.05).Logistics regression screen showed that the operation time,preoperative neoadjuvant chemotherapy,the distance between the lower margin of tumor and perianal region and the growth of peripheral tumor were the predictive factors of poor anastomosis healing.According to Logistics regression,the ROC curve was drawn,and the AUC was 0.892(95％CI:0.813～0.945),the sensitivity was 75.81％,and the specificity was 89.47％.Youden index is 0.6528;Using Bootdtrap technology to draw the calibration curve of the model shows that the model has good prediction efficiency.Conclusion Long operation time,preoperative neoadjuvant chemotherapy,the distance between the lower edge of tumor and perianal region＜7cm,and the growth of peripheral tumor are the risk factors for postoperative patients with colorectal cancer with poor anastomotic healing.The prediction model can be used to screen people with poor anastomotic healing and has good prediction efficiency.

In the outbreak of COVID-19,triage procedures based on epidemiology were implemented in a local hospital in Changsha to control the transmission of SARS-CoV-2 and avoid healthcare-associated infection.This re-trospective study analyzed the data collected during the triage period and found that COVID-19 patients were en-riched 7 folds into the Section A designated for patients with obvious epidemiological history.On the other side,nearly triple amounts of visits were received at the Section B for patients without obvious epidemiological history.8 COVID-19 cases were spotted out of 247 suspected patients.More than 50％of the suspected patients were submi-tted to multiple rounds of nucleic acid analysis for SARS-CoV-2 infection.Of the 239 patients who were diagnosed as negative of the virus infection,188 were successfully revisited and none was reported as COVID-19 case.Of the 8 COVID-19 patients,3 were confirmed only after multiple rounds of nucleic acid analysis.Besides comorbidities,delayed sharing of epidemiological history added complexity to the diagnosis in practice.The triaging experience and strategy will be helpful for the control of infectious diseases in the future.

The Health-Related Quality of Life (HRQoL) pertains to patients' subjective contentment concerning their physical, psychological, and social well-being throughout disease treatments. Predominantly employed HRQoL metrics in spinal metastases comprise the 36-item Short-Form Health Survey (SF-36), EuroQoL Five Dimensions Questionnaire (EQ-5D), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30), and the Functional Assessment of Cancer Therapy-General (FACT-G). In clinical applications, due to their broad application and diverse disease types, combined with the lack of specificity in the scale content and the prolixity of their questionnaires, these tools often fail to capture the nuanced experiences of patients, thereby compromising the reliability and validity of the results. The Spine Oncology Study Group Outcomes Questionnaire (SOSGOQ), developed by the Spine Oncology Study Group, offers a tailored metric for spinal metastases, encapsulating both specificity and inclusivity. Its proven robust reliability and validity make it invaluable for decision-making and therapeutic efficacy appraisals. The Patient-Reported Outcome Measurement Information System (PROMIS), a novel metric suitable across many medical disciplines, facilitates cross-sector data acquisition, substantially augmenting the precision, sensitivity, and credibilityof assessments, and is pivotal in clinical investigations and interventions. As it continually evolves, PROMIS consistently outperforms traditional metrics in evaluative capacities, exhibiting impressive and consistent proficiency in prognostications, preoperative assessments, and therapeutic outcome evaluations within the spinal metastasis domain. Presently, Chinese research on the HRQoL of spinal metastasis patients remains scant, and choosing an apt, precise, and dependable metric holds significant clinical relevance. Drawing upon extant scholarly publications, this review concluded the current global HRQoL tools for spinal metastases, aiming to furnish insights for the clinical management and research pertaining to spinal metastases.

Objective: To evaluate treatment responses, outcomes, and prognostic factors in adults with secondary acute myeloid leukemia (sAML) . Methods: Between January 2008 and February 2021, date of consecutive cases of younger than 65 years of adults with sAML were assessed retrospectively. Clinical characteristics at diagnosis, treatment responses, recurrence, and survival were evaluated. Logistic regression and Cox proportional hazards model were employed to determine significant prognostic indicators for treatment response and survival. Results: 155 patients were recruited, including 38, 46, 57, 14 patients belonging to t-AML, and AML with unexplained cytopenia, post-MDS-AML, and post-MPN-AML, respectively. In the 152 evaluable patients, the rate of MLFS after the initial induction regimen was 47.4%, 57.9%, 54.3%, 40.0%, and 23.1% in the four groups (P=0.076) . The total rate of MLFS after the induction regimen was 63.8%, 73.3%, 69.6%, 58.2%, and 38.5% (P=0.084) , respectively. Multivariate analysis demonstrated that male gender (OR=0.4, 95% CI 0.2-0.9, P=0.038 and OR=0.3, 95% CI 0.1-0.8, P=0.015) , SWOG cytogenetic classification into unfavorable or intermediate (OR=0.1, 95% CI 0.1-0.6, P=0.014 and OR=0.1, 95% CI 0.1-0.3, P=0.004) and receiving low-intensity regimen as induction regimen (OR=0.1, 95% CI 0.1-0.3, P=0.003 and OR=0.1, 95%CI 0.1-0.2, P=0.001) were typical adverse factors impacting the first CR and the final CR; PLT<45 × 10(9)/L (OR=0.4, 95%CI 0.2-0.9, P=0.038) and LDH ≥258 U/L (OR=0.3, 95%CI 0.1-0.7, P=0.005) were independent factors for CR. Among the 94 patients with achieving MLFS, 46 cases had allogeneic hematopoietic stem cell transplantation. With a median follow-up period of 18.6 months, the probabilities of relapse-free survival (RFS) and overall survival (OS) at 3 years were 25.4% and 37.3% in patients with transplantation, and in patients with chemotherapy, the probabilities of RFS and OS at 3-year were 58.2% and 64.3%, respectively. At the time of achieving MLFS, multivariate analysis revealed that age ≥46 years (HR=3.4, 95%CI 1.6-7.2, P=0.002 and HR=2.5, 95%CI 1.1-6.0, P=0.037) , peripheral blasts ≥17.5% at diagnosis (HR=2.5, 95%CI 1.2-4.9, P=0.010 and HR=4.1, 95%CI 1.7-9.7, P=0.002) , monosomal karyotypes (HR=4.9, 95%CI 1.2-19.9, P=0.027 and HR=28.3, 95%CI 4.2-189.5, P=0.001) were typical adverse factors influencing RFS and OS. Furthermore, CR after induction chemotherapy (HR=0.4, 95%CI 0.2-0.8, P=0.015) and transplantation (HR=0.4, 95%CI 0.2-0.9, P=0.028) were substantially linked to longer RFS. Conclusion: Post-MDS-AML and post-MPN-AML had lower response rates and poorer prognoses than t-AML and AML with unexplained cytopenia. In adults with male gender, low platelet count, high LDH, and SWOG cytogenetic classification into unfavorable or intermediate at diagnosis, and receiving low-intensity regimen as the induction regimen predicted a low response rate. Age ≥46 years, a higher proportion of peripheral blasts and monosomal karyotype had a negative effect on the overall outcome. Transplantation and CR after induction chemotherapy were greatly linked to longer RFS.

ObjectiveTo compare the effects of programmed intermittent epidural bolus （PIEB） and continuous epidural infusion （CEI） on enhanced recovery after cesarean section. MethodsTotally 120 women scheduled to undergo elective cesarean section under combined spinal and epidural anesthesia， aged 18-45 years， with single fetus， full-term pregnancy （≥37 weeks）， ASA grade II or III， were recruited， with 60 cases in each group. At the end of the surgery， after a similar epidural loading dose， patients were randomLy assigned to receive either PIEB （6 mL·h^-1 beginning 30 minutes after the loading dose） or CEI （6 mL·h^-1， beginning immediately after the loading dose） for the maintenance of analgesia with 0.1% ropivacaine. At 2， 6， 12， 24 and 36 h postoperatively， VAS score was used to evaluate the composite pain， and Bromage Score was used to evaluate the degree of lower extremity motor block. The time to first flatus， time to first ambulation and the satisfaction scores were also recorded. ResultsThe VAS scores at 12， 24 and 36 h postoperatively and the lower extremity motor block scores at 6， 12 and 24 h postoperatively in the PIEB group were significantly lower than those in the CEI group （P < 0.01）. The epidural analgesic dosage was less in the PIEB group than that of the CEI group （P=0.002）. The time to first flatus and time to first ambulation were significantly shorter than those in the CEI group （P < 0.05）. The satisfaction scores were significantly higher in the PIEB group than in the CEI group （P < 0.05）. There was no significant difference in the first urination time after urinary catheter removal and the length of hospital stay between the two groups （P > 0.05）. ConclusionCompared with CEI， PIEB provides better postoperative analgesia， less motor block scores， lower epidural analgesic dosage， shorter the time to first flatus and defecation and time to first ambulation， and greater patient satisfaction， which is more consistent with the ERAS concept of analgesia.
