Objective:To analyze the survival time and influencing factors of human immunodeficiency virus(HIV)infected individuals and acquired immunodeficiency syndrome(AIDS)patients in Yancheng City from 2016 to 2020.Methods:The survival and death information of HIV/AIDS patients in Yancheng city from 2016 to 2020 was collected through the National AIDS Comprehensive Prevention and Control Information System. A retrospective cohort study was conducted,and the survival status of HIV/AIDS patients was analyzed using life tables. The Cox proportional hazards regression model was used to analyze the influencing factors of survival time.Results:A total of 1 411 HIV/AIDS patients were included in this study. By the end of the study,the cumulative survival rates of patients at 1-5 years were 93.90%,91.95%,91.24%,90.35%,and 90.12%,respectively. The multivariate Cox proportional hazards model analysis results showed that the risk of death for the age group of ≥60 years at the first diagnosis of HIV positive was 1.54 times that of the <45 years age group(95% CI:1.05-2.28);the risk of death for the CD4 +T lymphocyte(CD4)count groups of 200-349 cells/μl,350-499 cells/μl,and ≥500 cells/μl was 0.30 times(95% CI:0.19-0.47),0.21 times(95% CI:0.11-0.42),and 0.12 times(95% CI:0.04-0.37)that of the <200 cells/μl group,respectively;the risk of death for those who received antiviral treatment was 0.08 times(95% CI:0.05-0.12)that of those who did not receive antiviral treatment;and the risk of death from HIV/AIDS for cases detected through medical institution testing is 2.23 times(95% CI:1.14-3.51)that of cases detected through testing and counseling. Conclusion:The study of HIV/AIDS in Yancheng city from 2016 to 2020 shows that older age at diagnosis,lower initial CD4 +T lymphocyte count,no antiviral treatment,and detection by medical institutions are associated with higher risk of death. It is recommended to expand testing,improve treatment compliance,and promote early detection and treatment of high-risk groups to prolong survival.

Objective:To investigate the application value of D-dimer (D-D) as the primary indicator, combined with NT-proBNP and neutrophil percentage in the differential diagnosis of acute aortic dissection (AAD), pulmonary embolism (PE), and acute myocardial infarction (AMI).Methods:A retrospective case-control study was conducted, including 764 patients with acute chest pain who presented to the Emergency Department of Beijing Fuwai Hospital from March 1st, 2024, to February 28th, 2025. Patients were clinically diagnosed with AAD (299 cases) and other acute chest pain conditions (AMI 425 cases, PE 40 cases). The AAD group had the age of 56.00 (45.00, 64.00) years old with 226 males (75.59%); the AMI group had a median the age of 65.00 (55.00, 70.00) years with 339 males (79.76%); and the PE group had the age of 70.00 (59.75, 74.00) years with 15 males (37.50%). Baseline clinical data were collected and compared among the three groups, including general parameters such as heart rate, systolic blood pressure, and diastolic blood pressure. Laboratory parameters included N-terminal pro-brain natriuretic peptide (NT-proBNP), prothrombin time (PT), activated partial thromboplastin time (APTT), D-D, cardiac troponin I (cTnI), myoglobin, creatine kinase-MB (CK-MB), white blood cell count, neutrophil percentage, lymphocyte percentage, platelet count, and mean platelet volume (MPV). Comparisons between groups were performed using the Kruskal-Wallis rank-sum test and χ2 test. Independent discriminatory factors were identified through multivariate logistic regression analysis, and the diagnostic performance of individual indicators and combined models were analyzed using receiver operating characteristic (ROC) curves.Results:The D-D level in the AAD group [3.93 (1.48, 19.59) μg/ml] was significantly higher than that in the AMI group [0.26 (0.14, 0.56) μg/ml] and PE group [2.13 (0.84, 6.13) μg/ml] ( F=200.12, P<0.001). Multivariate analysis showed that D-D, NT-proBNP, neutrophil percentage, and lymphocyte percentage were all independent factors for differentiating AAD from AMI. NT-proBNP, total white blood cell count, neutrophil percentage, and lymphocyte percentage were independent predictors for differentiating AAD from PE. ROC analysis showed that D-D had an area under the curve (AUC) of 0.93 (95% CI 0.91-0.95) for differentiating AAD from AMI, with a sensitivity of 81.6% and specificity of 92.9%. In the differential diagnosis between AAD and PE, the model combining D-dimer, NT-proBNP, and neutrophil percentage had an AUC of 0.86 (95% CI 0.80-0.91), with a sensitivity of 85.0% and a specificity of 72.5%. Conclusion:D-D has significant value in the differential diagnosis of AAD from AMI and PE, with particularly good individual diagnostic performance for differentiating AAD from AMI. Combining NT-proBNP and neutrophil percentage can significantly improve differential diagnostic performance.

Objective:
Hand clumsiness and reduced hand dexterity can signal early signs of degenerative cervical myelopathy (DCM). While the 10-second grip and release (10-s G&R) test is a common clinical tool for evaluating hand function, a more accessible method is warranted. This study explores the use of deep learning-enhanced hand grip and release test (DL-HGRT) for predicting DCM and evaluates its capability to reduce the duration of the 10-s G&R test.
Methods:
The retrospective study included 508 DCM patients and 1,194 control subjects. Propensity score matching (PSM) was utilized to minimize the confounding effects related to age and sex. Videos of the 10-s G&R test were captured using a smartphone application. The 3D-MobileNetV2 was utilized for analysis, generating a series of parameters. Additionally, receiver operating characteristic curves were employed to assess the performance of the 10-s G&R test in predicting DCM and to evaluate the effectiveness of a shortened testing duration.
Results:
Patients with DCM exhibited impairments in most 10-s G&R test parameters. Before PSM, the number of cycles achieved the best diagnostic performance (area under the curve [AUC], 0.85; sensitivity, 80.12%; specificity, 74.29% at 20 cycles), followed by average grip time. Following PSM for age and gender, the AUC remained above 0.80. The average grip time achieved the highest AUC of 0.83 after 6 seconds, plateauing with no significant improvement in extending the duration to 10 seconds, indicating that 6 seconds is an adequate timeframe to efficiently evaluate hand motor dysfunction in DCM based on DL-HGRT.
Conclusion
DL-HGRT demonstrates potential as a promising supplementary tool for predicting DCM. Notably, a testing duration of 6 seconds appears to be sufficient for accurate assessment, enhancing the test more feasible and practical without compromising diagnostic performance.

Objective:To investigate the effect of inflammatory factors(IL-2,INF-γ,IL-10,TNF-α)and CD4+and CD8+T cells in vaginal lavage in high-grade cervical squamous intraepithelial lesions(HSIL)and early cervical cancer(CC).Methods:To collect clinical data of HSIL(n=120)and early CC patients(n=44)after high-risk human papilloma virus(HR-HPV)infection.And healthy middle-aged women not infected with HR-HPV were randomly selected as control.The clinical data of the subjects in three groups were compared,inflammatory factors distribution and ratio of CD4+and CD8+T cells in serum and vaginal lavage fluid were compared.Multivariate Logistic regression performed to analyze the influencing factors of HSIL progression to early CC,ROC and calibration plot were drawn to evaluate the model.Results:The difference was not statistically significant in serum IL-2,INF-γ,IL-10,TNF-α levels,CD4+T cell distribution,CD8+T cell distribution and CD4+/CD8+ratio in sub-jects of control group,HSIL group and early CC group(P>0.05).The difference was statistically significant in the vaginal lavage levels of IL-2,INF-γ,IL-10,TNF-α levels,CD4+T cell distribution,CD8+T cell distribution and CD4+/CD8+ratio(P<0.05),plus the level of HSIL patients was higher than that of control subjects(P<0.05).Logistic regression analysis showed that parity>2(OR=3.119,95%CI:4.353~6.737)and the percentage of CD4+T cells in vaginal lavage fluid(OR=0.327,95%CI:0.188-0.478)in model 2(P<0.001,AUC=0.908),CD4+/CD8+(OR=0.809,95%CI:0.356-1.868)(P<0.001,AUC=0.873)in model 3 has an independent influence on the development of HSIL to early CC;the difference is not significant(Z=1.550 4,P=0.121)in ROC curves of the two models.CD4+/CD8+ratio as only one indictor in Model 3 can be good predic-tion,and the calibration curve of this model is close to the standard curve.Conclusions:After HR-HPV infection,the systemic immune status does not participate in HSIL and HSIL progression to early CC,but the cervical local immune status is involved,in which CD4+/CD8+T cell ratio is an independent protective factor.
