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.

The struggle between healthy qi and pathogenic factors runs through the whole process of the formation and development of diabetic cardiomyopathy(DCM),and autophagy is the main regulator of cardiac homeostasis and function.Based on the theory of healthy qi and pathogenic factors,the autophagy state of DCM was understood.In the early stage of DCM,it is mainly characterized by deficiency of healthy qi and supplemented by pathogenic excess.In the middle stage,it is characterized by deficiency of healthy qi and pathogenic excess.In the late stage,it is mainly characterized by pathogenic excess and supplemented by deficiency of healthy qi.TCM clinical practice adheres to the principle of"strengthening the healthy qi and eliminating pathogenic factors",which aims to restore the dynamic balance of autophagy in the body by adjusting the balance between healthy qi and pathogenic factors,and ultimately improve the prognosis of DCM.This article took the theory of healthy qi and pathogenic factors as the starting point,and elaborated on the role of autophagy in the development of DCM from macro and micro perspectives.It explored Chinese materia medica intervention plans for different stages of DCM,providing theoretical reference for the regulation of autophagy in DCM by TCM.

Objective This study aimed to investigate the prognostic impact of different subtypes of metastatic renal cell carcinoma(mRCC)and establish corresponding predictive models using the Surveillance,Epidemiology,and End Results(SEER)database.Methods Clinical data of 2595 patients diagnosed with mRCC from 2010 to 2015 were extracted from the SEER database,including age,gender,race,tumor size,and metastatic sites.Patients were divided into clear cell renal cell carcinoma(ccRCC)group and non-clear cell renal cell carcinoma(non-ccRCC)group.Firstly,Kaplan-Meier survival analysis was performed for both groups,followed by uni-variate and multivariate COX regression analysis.Based on the results of univariate analysis,common factors affecting prognosis were de-termined.Combining the results of multivariate analysis,prognostic nomograms were established for ccRCC group and non-ccRCC group respectively,and the performance of the models was evaluated.Results The median overall survival(OS)of ccRCC group and non-ccRCC group were 18months and 11 months respectively.Univariate analysis indicated that age,T stage,bone metastasis,liver metasta-sis,and log odds of positive lymph nodes(LODDS)were common prognostic factors for different subtypes of mRCC patients.In addition,gender,tumor differentiation degree,whether receiving radiotherapy or chemotherapy,marital status,tumor size,N stage,lung metastasis and brain metastasis were also found to be associated with prognosis in ccRCC group.The OS nomogram model for ccRCC group had good predictive performance while the model for non-ccRCC group had poor performance,which might be related to the small sample size in this group.Conclusion Prognostic factors for different subtypes of mRCC are both homogeneous and heterogeneous.The prognostic pre-diction model established in this study can provide individualized treatment decision support for clinicians,thereby potentially improving patient prognosis.

Objectives:To investigate the imaging factors influencing the early prognosis of syrinx in patients with Chiari malformation type Ⅰ(CM Ⅰ)and syringomyelia(SM)who underwent posterior fossa decompression(PFD).Methods:Clinical data of 60 patients with CM Ⅰ and SM treated in the Department of Neurosurgery of Peking University Third Hospital from March 2013 to November 2022 were analyzed retrospectively.There were 18 males and 42 females with an average age of 48.8±9.1(range,27-65)years old.All the patients un-derwent PFD.Imaging assessments were performed preoperatively by cervical spine MRI and X-ray,and pa-rameters were collected,including maximum anterior-posterior and transverse diameters of syrinx,spinal cord anterior-posterior diameter,longitudinal distances of bulbo-pontine sulcus,fourth ventricle and cerebellar ton-sil,length of McRae line,length of clivus,clivus-canal angle,C0-C2 and C2-C7 Cobb angles as well as cervical sagittal vertical axis.The maximum syrinx/cord ratio and maximum syrinx area were calculated.With-in 1 month postoperatively,the maximum anterior-posterior diameter of syrinx was measured again by cervical spine MRI and its change rate was calculated to evaluate the early prognosis of syrinx.The patients were di-vided into improved(the change rate≥20％)and unimproved(the change rate＜20％)groups.The imaging find-ings were compared between the two groups,and a multi-variate logistic regression analysis was employed to identify significant predictors.Results:All the patients were followed up for 12.2±7.1d(range,5-31d).After PFD surgery,24 cases were improved in syrinx(the improved group),while 36 cases were not improved(the u-nimproved group).Age and gender were not significantly different between the two groups(P＞0.05).Postopera-tively,there were 2 cases with fever,2 cases with transient occipital pain,4 cases with CSF leakage,1 case with poor incision healing,and there was no significant difference of overall complication ratio between the two groups(P＞0.05).The clivus-canal angle and cervical sagittal vertical axis of CM Ⅰ patients in improved group(153.47°±9.99°,22.10±11.10mm)were significantly greater than those of unimproved patients(147.98°±9.55°,15.83±9.00mm)(P＜0.05).The maximum transverse diameter of syrinx in improved group(8.34±3.20mm)was significantly smaller than that of unimproved group(10.36±3.71mm,P＜0.05).No significant differences were found in other preoperative imaging parameters(P＞0.05).The multi-variate logisitic analysis revealed that the maximum transverse diameter of syrinx before operation was a risk factor of syrinx size reduction(OR=1.281,95％CI 1.042-1.576,P＜0.05),while the offset distance of cervical sagittal vertical axis acted as a protective factor of syrinx size reduction(OR=0.916,95％CI 0.853-0.984,P＜0.05).Conclusions:In patients with CM Ⅰand SM,preoperative maximum transverse diameter of syrinx and offset distance of cervical sagittal vertical axis are independent influencing factors for early postoperative prognosis of syrinx.

Objective:To explore the prognosis of patients with gastric cancer peritoneal metastasis (PM) receiving programmed cell death-1 (PD-1) antibody therapy, and investigate the biomarkers that affect the prognosis of anti-PD-1 therapy.Methods:This restrospecific study collected the clinic-pathological data of 56 patients with peritoneal metastasis of gastric cancer who received first-line treatment in the Nanjing Drum Town Hospital from March 2020 to September 2023, among which 41 had received anti-PD-1 immunotherapy and 15 hadn't. The relationship between overall survival (OS) and anti-PD-1 immunotherapy was evaluated by Kaplan-Meier analysis. The relationship between baseline peripheral blood indicators and treatment response of patients with anti-PD-1 treatment was analyzed using unpaired t-test. Subsequently, the Cox proportional risk regression model was used to explore the clinical prognostic factors that may affect anti-PD-1 immunotherapy by univariate and multivariate analysis. The clinical prognostic factors included baseline data and baseline peripheral blood indexes such as anti-PD-1 treatment lines, Eastern Cooperative Oncology Group performance status (ECOG PS), combined positive score (CPS), expression of human epidermal growth factor receptor 2 (Her-2), EBER status, pathological types, other metastatic lesions, ascites content before immunotherapy, with or without abdominal drainage during anti-PD-1 treatment, blood lipid indicators, inflammatory indicators, and tumor indicators. Results:Kaplan-Meier survival statistics showed similar OS (15.9 vs. 15.2 months, P=0.600) in patients with anti-PD-1 therapy compared to those without anti-PD-1 therapy. Patients with baseline high-density lipoprotein (HDL) ≥0.97 mmol/L ( n=22) demonstrated a significantly longer median OS compared to those with HDL＜0.97 mmol/L (15.2 vs. 13.5 months; P=0.018). Similarly, the cohort with apolipoprotein A1 (ApoA1) levels ≥0.86 g/L ( n=21) showed superior survival outcomes, with a median OS of 17.7 months versus 12.3 months in the ApoA1＜0.86 g/L group ( n=20; P=0.006). In contrast, elevated baseline alpha-fetoprotein (AFP) levels ( n=2) were associated with markedly reduced survival (median OS: 5.7 vs. 15.2 months in normal AFP group, n=37; P=0.005). Notably, elevated pretreatment ApoA1 levels correlated with enhanced immunotherapy response ( P=0.017). Multivariate Cox regression analysis revealed that ApoA1 deficiency (≥0.86 g/L) independently predicted better OS following PD-1 antibody therapy ( HR=0.35, 95% CI: 0.12-0.98, P=0.046) in gastric cancer patients with PM. Conclusions:In our study, it is first proposed that ApoA1 could be a significant predictor of the survival advantages of immunotherapy in gastric cancer patients with PM.

Objective:To explore the serum miRNA-144-5p (miR-144-5p) level in liver cancer patients and its relationship with clinical characteristics, as well as the target genes of miR-144-5p and the possible pathogenic mechanisms.Methods:The morning fasting serum samples were retrospectively collected from 100 newly diagnosed liver cancer patients (liver cancer group) before any treatment in Shanxi Province Cancer Hospital from June 2019 to June 2020, as well as 100 healthy individuals (healthy control group) during physical examinations in the same period. The real-time fluorescence quantitative polymerase chain reaction method was used to measure the transcription level expression of miR-144-5p in serum. The high and low expressions of miR-144-5p in patients were determined based on the median relative expression level of miR-144-5p; the distribution differences between patients with high and low expressions of miR-144-5p among different clinical pathological features were compared. The online tools miRDB, TargetScan 8.0 and miRWalk were used to predict potential target genes for miR-144-5p, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed through a bioinformatics platform, and complementary sequences between miR-144-5p and target genes were analyzed using RNA22 software.Results:The median age of the liver cancer group was 54 years old, ranging from 38 to 74 years old, including 80 males (80.0%) and 20 females (20.0%); the median age of the healthy control group was 46 years old, ranging from 34 to 66 years old, including 69 males (69.0%) and 31 females (31.0%); there was no statistically significant difference in age and gender composition between the two groups (both P > 0.05). The median transcription level relative expression of miR-144-5p in liver cancer patients was lower than that in the healthy control group [ M ( Q1, Q3)] [0.311 (0.066, 2.270) vs. 1.067 (0.263, 3.620)], and the difference was statistically significant ( Z = -4.16, P < 0.001). The proportion of patients with low expression of miR-144-5p was higher in the group with maximum diameter of tumor > 5 cm compared to the group with maximum diameter of tumor ≤5 cm [59.3% (35/59) vs. 36.6% (15/41)] and in the group with metastasis compared to the group without metastasis [60.4% (29/48) vs. 40.4% (21/52)], and the differences were statistically significant (both P < 0.05). There was no statistically significant difference in the distribution of patients with high and low expressions of miR-144-5p among different subgroups based on gender, age >55 years, presence of hepatitis, cirrhosis, alpha fetoprotein >400 μ g/L, and differentiation degree (all P > 0.05). According to predictions, there were 34 miR-144-5p target genes shared by the three bioinformatics online tools. GO and KEGG enrichment analyses showed that these target genes were associated with ubiquitination, primarily enriched in the ubiquitin-mediated proteolysis pathway (hsa04120) and the mTOR signaling pathway (hsa04150). RNA22 software analysis showed that miR-144-5p mainly had complementary sequences with 3' untranslated regions of UBR5 and UBE4A genes. Conclusions:The serum miR-144-5p level in liver cancer patients is relatively low, and its expression level may be related to tumor size and metastasis. miR-144-5p may affect the occurrence and development of liver cancer by regulating ubiquitination level through target genes such as UBR5 and UBE4A.

Objective To observe the value of whole-brain CT perfusion(CTP)parameters at different time and clinical data for predicting delayed cerebral ischemia(DCI)and 3-month poor prognosis in patients with aneurysmal subarachnoid hemorrhage(aSAH).Methods Totally 127 aSAH patients were retrospectively enrolled.Clinical and CTP data within 24 h of symptom onset and during DCI time window(DCITW)were collected.The patients were divided into DCI group(n=34)and non-DCI group(n=93)based on DCI occurred or not during hospitalization,also into poor outcome group(modified Rankin scale[mRS]≥3,n=36)and good outcome group(mRS≤2)based on 3-month's follow-up.Multivariate logistic regression was performed to select independent predictive factors among variates being significantly different between groups.Then receiver operating characteristic curve was drawn,and the area under the curve(AUC)was calculated to evaluate the predictive performance of logistic regression model.Results Patients'age,modified Fisher score(mFS),subarachnoid hemorrhage early brain edema score(SEBES)and mean flow extraction product(mFEP)within 24 h of onset were all identified as independent predictive factors of DCI,and the AUC of their combination for predicting DCI during hospitalization was 0.817.Patients' age and mFS within 24 h of onset,alternatively,World Federation of Neurosurgical Societies(WFNS)grade and mFEP during DCITW were all independent predictive predictors of 3 months' prognosis,and the combination of the latter two showed better predictive performance(AUC=0.922)tahn the former two(AUC=0.822,P＜0.05).Conclusion Whole-brain CTP parameters combined with clinical data within 24 h of onset of aSAH could be used to predict the occurrence of DCI during hospitalization,whole-brain CTP parameters during DCITW could be used to predict 3 months'poor prognosis.
