ObjectiveTo investigate the therapeutic effects of direct-acting antiviral agents (DAAs) combined regimens for hepatitis C virus (HCV) patients in Dehong Prefecture, Yunnan Province from 2022 to 2024, to analyze the characteristics of treatment failure patients, so as to provide a basis for discovering more effective treatment regimens in the future. MethodsData on HCV prevention and treatment in Dehong Prefecture was extracted from the China Disease Control and Prevention Information System. A total of 617 patients with HCV antiviral therapy were included, and the differences in variable characteristics among patients with different genotypes were analyzed using comparative statistical tests, including basic socio-demographic characteristics, biochemical testing indicators, and information on previous treatment and current treatment. In addition, the cure rate of HCV patients with diverse characteristics was compared, and the potential causes of treatment failure were explored simultaneously. ResultsThe cure rate of HCV was 96.8%, and statistically significant differences were observed in aspartate transaminase (AST) and alanine transaminase (ALT) levels, previous antiviral therapy history and initial treatment regimens among patients with different HCV genotypes (all P<0.05). Among the multi-type combination regimens, the cure rate of sofosbuvir (SOF)-containing regimens was 97.00%, that of velpatasvir (VEL)-containing regimens was 95.45%, and the cure rate of other treatment regimens, including the regimens with ribavirin (RIB) intervention, was 93.10%. Among the patients with treatment failure, 45.00% had genotype 3, 40.00% had abnormal abdominal ultrasound results, and all presented with elevated baseline AST test levels. ConclusionThe clinical treatment of HCV patients should consider the differences in genotype and biochemical test results. DAAs combined regimens for HCV have achieved a high cure rate in Dehong Prefecture and are applicable to HCV patients with diverse clinical characteristics, providing research evidence for wider application.

ObjectiveTo explore the prevalence and influencing factors of multimorbidity among the HIV-infected individuals receiving anti-viral therapy (ART) in Dehong Prefecture of Yunnan Province, so as to provide a reference for the long-term follow-up management of HIV-infected patients and the comprehensive prevention and treatment of chronic diseases. MethodsA cross-sectional study was conducted to investigate the multimorbidity burden among the HIV-infected adults receiving ART in Dehong Prefecture from January to July 2021 and a self-designed questionnaire was used to analyze relevant disease indicators. Multivariate logistic regression analysis was used to investigate the influencing factors of multimorbidity among the HIV-infected individuals. ResultsA total of 3 946 HIV-infected individuals receiving ART were enrolled in this study, of which 63.7% aged ≤50 years, with a male to female ratio of 1.1∶1. Among the 3 946 cases, 825 of them had ≥2 comorbidities, with a co-prevalence rate of 20.9% (95%CI:19.6%‒22.2%), and the main comorbidities were dyslipidemia, diabetes, and hypertension. Multivariate logistic regression analysis showed that 40≤ aged <50 years (aOR=1.86, 95%CI: 1.45‒2.40, P<0.001), 50≤ aged ≤85 years (aOR=3.75, 95%CI: 2.93‒4.80, P<0.001), Dai nationality (aOR=1.21, 95%CI: 1.01‒1.47, P=0.043), BMI≥24.0 kg∙m^-2 (aOR=1.79, 95%CI: 1.49‒2.14, P<0.001), 10.0≤ with ART duration for <12.5 years (aOR=1.49, 95%CI: 1.05‒2.12, P=0.024), with ART duration for ≥12.5 years (aOR=1.50, 95%CI: 1.05‒2.15, P=0.026), use of second-line HIV therapy (aOR=1.43, 95%CI: 1.19‒1.70, P<0.001) and other therapy options (aOR=3.16, 95%CI: 2.17‒4.61, P<0.001) were positively correlated with multimorbidity. ConclusionThe prevalence of multimorbidity among the HIV-infected individuals receiving ART in Dehong Prefecture is high, which is associated with the advancing age and prolonged treatment time, particularly with a significant burden of dyslipidemia, diabetes, and hypertension. Comprehensive surveillance and targeted management of comorbidities, along with ART follow-up, need to be strengthened in the future.

Objective: To establish a dynamic syndromic surveillance system in the border areas of Yunnan Province based on information technology, evaluate its effectiveness and timeliness in the response to common communicable disease epidemics and improve the communicable disease prevention and control in border areas. Methods: Three border counties were selected for full coverage as study areas, and dynamic surveillance for 14 symptoms and 6 syndromes were conducted in medical institutions, the daily collection of information about students' school absence in primary schools and febrile illness in inbound people at border ports were conducted in these counties from January 2016 to February 2018 to establish an early warning system based on mobile phone and computer platform for a field experimental study. Results: With syndromes of rash, influenza-like illness and the numbers of primary school absence, the most common communicable disease events, such as hand foot and mouth disease, influenza and chickenpox, can be identified 1-5 days in advance by using EARS-3C and Kulldorff time-space scanning models with high sensitivity and specificity. The system is easy to use with strong security and feasibility. All the information and the warning alerts are released in the form of interactive charts and visual maps, which can facilitate the timely response. Conclusions: This system is highly effective and easy to operate in the detection of possible outbreaks of common communicable diseases in border areas in real time, so the timely and effective intervention can be conducted to reduce the risk of local and cross-border communicable disease outbreaks. It has practical application value.

Hypertensive intracerebral hemorrhage (ICH) is mostly single in basal ganglia, thalamus and pons. Simultaneous hemorrhage in other brain regions is relatively rare, accounting for only 5.6% of all hemorrhagic strokes, while bilateral symmetrical hemorrhage is extremely rare. A case of bilateral basal ganglia symmetrical hemorrhage is reported for clinical reference.

ObjectiveTo investigate the factors that influence the first CD4+T lymphocyte counts in newly reported HIV-infected cases aged 50 and above in Dehong Prefecture of Yunnan Province during 2016 to 2021， and to understand the patient immune status and disease progression so as to provide scientific basis for HIV prevention and control strategies in the future. MethodsData was collected from the national HIV/AIDS information system. Multivariate logistic regression was used for the analysis of factors affecting the first CD4+T lymphocyte counts. ResultsA total of 642 cases of HIV infection were newly reported， among them， 571 cases had CD4+T lymphocyte counts and 200 cases （35.03%） had CD4+T lymphocyte counts <200 cells·μL^-1. Patients who were in the 50-59 age group， male， divorced or widowed， and less educated were more likely to have CD4+T lymphocyte counts <200 cells·μL^-1. Compared with active testing consultants， forced reeducation through labor or drug rehabilitation cases were less likely to have CD4+T lymphocyte counts <200 cells·μL^-1. ConclusionThere is no obvious upward trend in newly reported HIV infected persons aged 50 years and above in Dehong Prefecture during 2016 to 2021. However， the situation of CD4+T lymphocyte counts <200 cells·μL^-1 is still serious. Attention should be paid to the key groups： male， Chinese nationality， farmers， Han nationality， married or divorced， junior high school education or below， and heterosexual transmission. It is necessary to strengthen the intervention in people aged 50 and above and improve the detection efficiency.

ObjectiveTo analyze the prevalence of HCV antibody positive and associated factors among drug users in Dehong Prefecture， Yunnan， and to provide scientific evidence for HCV prevention. MethodsQuestionnaire surveys and serological testing were conducted among 400 drug users continuously selected from four national AIDS sentinel surveillance in Dehong Prefecture between January and July during 2014‒2021. Results11 683 drug users were included. The prevalence of HCV antibody positive was 20.2% overall， and 14.9%， 20.1%， 22.4%， 19.8%， 22.5%， 20.6%， 24.5%， 19.0% from 2014 to 2021， respectively （trend Z=-3.78， P<0.001）. Multivariable analysis indicated the following were independently associated with HCV antibody positive： that older age （OR=1.02， 95%CI： 1.02‒1.03）， male （OR=1.70， 95%CI： 1.19‒2.42）， unmarried （OR=1.64， 95%CI： 1.44‒1.87）， divorced or widowed （OR=1.73， 95%CI： 1.48‒2.02）， Jingpo ethnicity （OR=1.39， 95%CI： 1.19‒1.63）， injection drug use （OR=15.46， 95%CI： 13.13‒18.12）， and HIV infection（OR=4.96， 95%CI：4.12‒5.99）. ConclusionThe prevalence of HCV antibody positive among drug users in Dehong Prefecture is high and increases with some fluctuations during 2014 to 2021， which highlights the need to develop interventions targeting this population.

The number of benign prostatic obstruction (BPO) patients in China is increasing, and patients tend to be younger and younger. The former "gold standard" scheme of transurethral resection of the prostate (TURP) is more suitable for patients with prostate volume ranging from 40 mL to 80 mL, which may lead to excessive resection in patients with small prostate volume and low efficiency in patients with large prostate volume. New minimally invasive techniques have been introduced,including prostate artery embolization, laser surgery (such as holmium, green, diode, and thulium), minimally invasive simple prostatectomy, transperineal laser ablation, prostatic urethral lift,and robot-assisted water jet ablation of the prostate. These methods are alternatives to TURP and increasingly used in the treatment of BPO. This article reviewed the advances in minimally invasive treatment of BPO.

Bladder cancer (BCa) is one of the most common cancers in urology,whose pathogenesis is still unclear. Methyltransferase-like 3(METTL3) is the most important part of N6-methyladenosine methyltransferase complex (m6A MTC),which mediates the methylation of mRNA to regulate the stability and translation process of mRNA. Researches have shown that METTL3 can promote BCa development via AFF4/NF-κB/MYC signaling network,which involves many kinds of signaling molecules. In addition,METTL3 can affect the expressions of AFF4,NF-κB and MYC,so as to affect their downstream signaling pathways and finally promote the malignant progression of tumor.
