Objective To investigate the prevalence, distribution characteristics, and influencing factors of mental health problems among the elderly, and to provide a scientific basis for policy-making.  Methods A convenience sampling method was used to investigate depression, anxiety, and cognitive function among permanent residents aged 65 and older at 59 mental health care sites for the elderly in Hubei Province. Multinomial logistic regression was employed to analyze influencing factors. Results The screening rates for depression, anxiety, and cognitive function at critical/high-risk levels among the elderly in Hubei Province were 9.7%, 5.4%, and 12.2%, respectively. Urban elderly had lower risks of depression and cognitive function at critical/high-risk levels compared to rural elderly (OR for critical depression = 0.640, P < 0.001; OR for high-risk depression = 0.595, P = 0.012; OR for critical cognitive function = 0.448, P < 0.001; OR for high-risk cognitive function = 0.188, P < 0.001). Six key population groups had higher risks of depression, anxiety, and cognitive function at critical/high-risk levels than others (OR for critical depression = 1.463, P < 0.001; OR for high-risk depression = 1.912, P < 0.001; OR for critical anxiety = 1.462, P < 0.001; OR for high-risk anxiety = 2.882, P < 0.001; OR for critical cognitive function = 1.381, P < 0.001; OR for high-risk cognitive function = 2.345, P < 0.001). A higher number of chronic diseases was associated with increased risks of critical and high-risk depression (OR for critical = 1.316, P < 0.001; OR for high-risk = 3.677, P < 0.001) and cognitive impairment (OR for critical depression = 1.316, P < 0.001; OR for high-risk depression = 3.677, P < 0.001; OR for critical anxiety = 1.512, P < 0.001; OR for high-risk anxiety = 1.801, P < 0.001). Conclusion It is recommended to expand mental health care sites in rural areas, improve the layout of mutual-support elderly care facilities, and explore sustainable models for rural elderly care. Efforts should also focus on enhancing social participation among the elderly through community-based activities, and strengthening cognitive screening and emotional regulation interventions, with particular attention to the mental health needs of older, isolated, and chronically ill individuals.

Objective To investigate the antibody levels against measles, rubella, and mumps in infants aged 0-8 months in Shanghai, and construct a decay trend model, and to provide evidence for formulating prevention and control strategies. Methods Serum samples were collected from infants aged 0 - 8 months at a children's medical center in Shanghai. Enzyme-linked immunosorbent assay (ELISA) was used to measure the IgG antibody levels against measles, rubella, and mumps. The antibody positive rates and antibody geometric mean concentration (GMC) in different age groups were analyzed. Results A total of 922 serum samples were collected. The GMC and positive rates for measles, rubella, and mumps antibodies were 2.11 (127.35 IU·L^-1) and 39.70%; 0.89 (7.89 IU·mL^-1) and 28.85%; and 1.89 (77.80 U·mL^-1) and 41.43%, respectively. There were statistically significant differences in antibody levels and positive rates across different age groups. With the highest levels observed at 0 months, a rapid decline began at 3 months, reaching the lowest levels by 7 months. After the first dose of the MMR vaccine at 8 months, antibody levels increased. A negative correlation was observed between age and GMC for measles, rubella, and mumps antibodies, showing a linear decay trend. The models were as follows: Ŷmeasles = −0.151X + 2.602 (R²=0.91，P＜0.001); Ŷrubella = −0.126X + 1.319(R²=0.98，P＜0.001); Ŷmumps = −0.122X + 2.327 (R²=0.94，P＜0.001). Conclusion The antibody levels for measles, rubella, and mumps in infants decline linearly with increasing age in months. The antibody levels in infants before 8 months of age primarily depend on maternal antibodies. It is recommended that MMR vaccination be promoted for women of childbearing age to enhance early passive immunity protection in infants.

ObjectiveTo analyze the epidemiological and clinical characteristics of the 21 confirmed monkeypox cases in a district of Chengdu City, and to provide scientific guidance for the prevention and control of subsequent monkeypox epidemics. MethodsData of confirmed monkeypox cases residing in this district were collected from the Disease Control and Prevention Information System of China. A retrospective descriptive epidemiological analysis was used to analyze the demographic, distributional and behavioral characteristics of the cases. ResultsThe first confirmed case of monkeypox was reported on July 5, 2023. Up to April 30, 2025, a total of 21 confirmed cases of monkeypox have been reported. All cases were male, with a mean age of (30.9±6.2) years. The highest proportion of cases(47.62%) was in the 30‒40 years age group. The majority were men who have sex with men (MSM) population (90.48%, 19/21). The results showed that 19.05% of cases were co-infected with HIV, and 19.05% had a history of syphilis infection. Within 21 days prior to symptom onset, 19 cases (90.48%) self-reported engaging in male-to-male sexual contact, among whom 10 cases (52.63%) reported having taken protective measures, while 9 cases (47.37%) did not take safety precautions. Thirteen cases (61.90%) had no travel history to areas with reported monkeypox cases during the 21 days before symptom onset. The predominant manifestation was exanthem (100%, 21/21), followed by fever (57.14%, 12/21) and lymphadenectasis (47.62%, 10/21). Among febrile cases, 50.00% (6/12) had low-grade fever (37.3‒38.0 ℃). All cases were identified through active medical consultation. The median interval from symptom onset to the first medical visit was 3 (2, 6) days, with a maximum interval of 14 days. The median interval from symptom onset to laboratory confirmation was 7 (5, 9) days. Six cases (28.57%) had two or more visits to the hospital, with bacterial infection being the primary initial diagnosis. ConclusionMonkeypox prevention and control efforts in a district of Chengdu City should prioritize MSM population and young and middle-aged adults aged 30 to <40 years. It is recommended to establish an integrated monkeypox epidemic prevention and control network by leveraging existing HIV/AIDS prevention and control network. Concurrently, accelerating the deployment of the national intelligent infectious disease monitoring and early warning front-end software will strengthen early detection capabilities and be beneficial for the overall effectiveness of epidemic prevention and control efforts.

Objective To investigate whether Danshen injection (DSI) can protect human brain organoids from oxidative stress damage by regulating the Nrf2 signaling pathway and its mechanism. Methods A Nrf2 plasmid was constructed, lentivirus was packaged and transfected into human induced pluripotent stem cell (hiPSC) to form a stable cell line. Brain organoids with Nrf2 overexpression (LV-Nrf2 group) and knockdown (sh-Nrf2 group) were constructed using kit. The transfection efficiency was verified by real-time fluorescence quantitative polymerase chain reaction. An oxidative stress injury model was established by inducing hydrogen peroxide (H₂O₂). Intervention was performed either in combination or without DSI pre-treatment. Cell viability was detected by Cell Counting Kit-8 (CCK-8), and the expression levels of Nrf2, malondialdehyde (MDA), interleukin (IL)-1β, sex-determining region Y-box protein 2 (SOX2) and neuronal-specific nuclear protein (NeuN) were detected by Western blot and immunofluorescence staining. Total RNA from human brain organoids was extracted for transcriptome sequencing and analysis. Results LV-Nrf2 group and sh-Nrf2 group brain organoid models were successfully constructed. The CCK-8 results determined that the oxidative stress model was established with 32 mmol/L H₂O₂ intervention conditions. The fluorescence expression of Nrf2 in LV-Nrf2 group was higher than that in control group, and the fluorescence expressions of MDA and IL-1β were lower than those in control group; sh-Nrf2 group showed a damage phenotype of low Nrf2 expression, high MDA and IL-1β expression (all P < 0.05). Compared with H₂O₂ group, the Nrf2 signal in DSI + H₂O₂ group was stronger, and the levels of MDA and IL-1β were lower. Among them, the protective effect of LV-Nrf2 was the most significant. H₂O₂ treatment could down-regulate the protein levels of Nrf2, SOX2 and NeuN, and DSI intervention could effectively reverse the downward trend of these indicators. Sh-Nrf2 could weaken the recovery effect of DSI on SOX2 and NeuN, while LV-Nrf2 could synergistically enhance the regulatory effect of DSI. Conclusions DSI may antagonize oxidative stress damage in human brain organoids through the Nrf2 signaling pathway, and maintaining the stability of the neural cell lineage is its core therapeutic characteristic.

As one of the major diseases threatening human health,the early accurate diagnosis and localization of tumors are crucial for formulating effective treatment plans.In recent years,molecular probes(MPs)have made significant progress in the field of biological imaging.With advantages such as high sensitivity,high specificity,and non-invasiveness,they have become a research hotspot in the field of tumor diagnosis and treatment.This paper systematically reviews the applications of MPs in tumor diagnosis and treatment,covering their classifications(such as fluorescent,photoacoustic,chemiluminescent,bioluminescent,and multimodal probes),design strategies(including active/pas-sive targeting mechanisms and the synergistic construction of identification units,imaging units,signal conversion units and treatment units),as well as detection principles.It also focuses on elabo-rating the research progress of MPs based on enzymes,receptors,reactive substances,and tumor microenvironment.Meanwhile,this paper emphasizes the advantages of multifunctional integration and multimodal imaging,and analyzes the challenges faced by MPs in clinical translation(such as biocompatibility and optimization of supporting equipment).It aims to provide ideas for the develop-ment of high-performance MPs and promote the advancement of precise and personalized tumor di-agnosis and treatment.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To explore the therapeutic efficacy and prognostic factors of combined rituximab and intensive chemotherapy for sporadic adult Burkitt lymphoma (BL) .Methods:This retrospective study examined the clinical and survival data of 30 patients newly diagnosed with BL between July 2011 and February 2023 at the Blood Diseases Hospital. Kaplan-Meier method was used for survival analysis, and the log-rank test was used for univariate analysis of prognostic factors.Results:The median age of the 30 patients was 43 years (24 - 66 years), and the male to female ratio was 3: 2. Extranodal invasion was present in 80% of the patients, with involvement of the bone marrow in 53.3% and central nervous system in 10.0%. The Ann Arbor stage was Ⅲ and Ⅳ in 86.7%. According to the number of Burkitt Lymphoma International Prognostic Index (BL-IPI) risk factors, patients were classified as low risk (0) in 20.0%, intermediate risk (1) in 43.3%, and high risk (≥2) in 36.7%. All patients were treated with an induction regimen of rituximab combined with intensive chemotherapy, with objective and complete response rates of 80.0% and 76.7%, respectively. The median follow-up was 49 months (6-153 months), and the 5-year progression-free survival (PFS) and overall survival (OS) rates were both (76.7±7.7) %. All patients with limited stage ( n=4) achieved continuous complete remission (CCR). Patients who had high risk, advanced stage sensitive to induction therapy ( n=10) sequentially received first-line autologous hematopoietic stem cell transplantation (auto-HSCT) as consolidation therapy; 9 patients achieved CCR, whereas 1 patient with central nervous system invasion developed early disease progression and died. The BL-IPI low, intermediate, and high risk groups had respective 5-year PFS rates of (83.3±15.2) %, 100.0%, and (45.5±15.0) % ( P=0.0069) and OS rates of (83.3±15.2) %, 100.0%, and (45.5±15.0) % ( P=0.0075). The main adverse effects of induction therapy were myelosuppression and secondary infections, which were effectively managed by appropriate symptomatic treatment. Univariate analysis demonstrated that worse PFS was associated with BL-IPI score ≥2 ( HR=4.90, 95% CI 1.02-23.45, P=0.0329) ; extranodal invasion at ≥2 sites ( HR=12.62, 95% CI 2.59-61.62, P=0.0021) ; and failure to achieve first complete response (CR1) after induction therapy ( HR=31.86, 95% CI 4.19-242.20, P<0.0001) . Conclusions:Intensive immunochemotherapy regimens were effective and well-tolerated by adult patients with highly aggressive BL. Treatment efficacy was ideal in patients with limited-stage disease, whereas prognosis was unsatisfactory in patients with high-risk BL-IPI. Sequential first-line auto-HSCT consolidation therapy may further improve outcomes in patients with high-risk advanced-stage disease who are sensitive to induction therapy. BL-IPI score ≥2, extranodal invasion at ≥2 sites, and failure to achieve CR1 after induction therapy were adverse prognostic factors in adult patients with BL.

Objective:To evaluate the clinical features of dystonia in patients with different types of atypical Parkinson syndrome (APS).Methods:A total of 104 patients with APS admitted in the Department of Neurology, Beijing Hospital from January 2015 to June 2023 were enrolled in the study, including 57 cases of multiple system atrophy (MSA), 38 cases of progressive supranuclear palsy (PSP) and 9 cases of corticobasal degeneration (CBD). Among 104 cases there were 63 males (60.6%), the mean age of patients was (62.3±8.9) years (54 to 73 years). The sex, age at onset, disease duration, first symptom, clinical features of dystonia and other neurological signs, response to levodopa therapy, numbers of Hoehn & Yahr scale≥3 after 3 years of disease, and MRI findings were documented in patients with different type APS.Results:The overall frequency of dystonia in this series was 45.2%(47/104), and 33.3% (19/57) for MSA group, 50.0% (19/38) for PSP group, 9/9 for CBD group. The types of dystonia were anterocollis, retrocollis, blepharospasm, oromandibular, foot/limb dystonia, Pisa syndrome and myoclonus. In all 47 cases presenting dydtonia, dystonia was not the first complaint and it did not respond to levodopa therapy.Conclusion:In this series of atypical Parkinson syndrome, dystonia is a common feature of the disease, while it is not the first symptom at disease onset, and usually does not respond to levodopa therapy.

Objective:To evaluate the efficacy of peritoneal dialysis (PD) in the treatment of acute kidney injury (AKI) in critically ill neonates.Methods:It was a retrospective study. The baseline characteristic data, PD protocols, PD catheter placement methods and clinical outcomes of AKI neonates who underwent PD in the General Hospital of Ningxia Medical University between July 2015 and December 2024 were collected and analyzed.Results:(1) Among the 8 neonates with AKI, gestational age was (30.38±6.02) weeks, and birth weight was 1 397.5 (839.0, 2 312.5) g, with 6 premature infants. The time from birth to AKI onset was 144 (48, 294) hours. The leading cause of AKI was sepsis (6/8). The treatment time of PD was (93.12±37.20) hours. (2) Renal function recovery: After PD treatment, urine output was significantly increased ( Z=-3.29, P<0.001), and serum creatinine was significantly decreased ( t=2.66, P=0.032). (3) Hyperkalemia: Six out of 8 patients presented with hyperkalemia, which significantly decreased after PD treatment ( t=3.37, P=0.008). (4) Acid-base balance:Five out of 8 neonates had metabolic acidosis, and 3 of 5 neonates achieved basically complete correction (including lactic acidosis). There was no statistically significant difference in acid-base balance indicators before and after PD treatment (all P>0.05). (5) PD-related complications: Two out of 8 patients experienced peritoneal dialysate leakage, and no other PD-related complications occurred. (6) Outcomes: The hospital stay was 27.0 (8.0, 57.5) days. Four out of 8 neonates survived, while the other 4 neonates died after withdrawal of treatment. The primary cause was multiple organ failure. Conclusions:PD is a safe and effective treatment for neonatal AKI, facilitating early renal recovery and correction of electrolyte and acid-base imbalances.
