[A multicenter prospective study on early identification of refractory Mycoplasma pneumoniae pneumonia in children].

Objective: To explore potential predictors of refractory Mycoplasma pneumoniae pneumonia (RMPP) in early stage. Methods: The prospective multicenter study was conducted in Zhejiang, China from May 1st, 2019 to January 31st, 2020. A total of 1 428 patients with fever >48 hours to <120 hours were studied. Their clinical data and oral pharyngeal swab samples were collected; Mycoplasma pneumoniae DNA in pharyngeal swab specimens was detected. Patients with positive Mycoplasma pneumoniae DNA results underwent a series of tests, including chest X-ray, complete blood count, C-reactive protein, lactate dehydrogenase (LDH), and procalcitonin. According to the occurrence of RMPP, the patients were divided into two groups, RMPP group and general Mycoplasma pneumoniae pneumonia (GMPP) group. Measurement data between the 2 groups were compared using Mann-Whitney U test. Logistic regression analyses were used to examine the associations between clinical data and RMPP. Receiver operating characteristic (ROC) curves were used to analyse the power of the markers for predicting RMPP. Results: A total of 1 428 patients finished the study, with 801 boys and 627 girls, aged 4.3 (2.7, 6.3) years. Mycoplasma pneumoniae DNA was positive in 534 cases (37.4%), of whom 446 cases (83.5%) were diagnosed with Mycoplasma pneumoniae pneumonia, including 251 boys and 195 girls, aged 5.2 (3.3, 6.9) years. Macrolides-resistant variation was positive in 410 cases (91.9%). Fifty-five cases were with RMPP, 391 cases with GMPP. The peak body temperature before the first visit and LDH levels in RMPP patients were higher than that in GMPP patients (39.6 (39.1, 40.0) vs. 39.2 (38.9, 39.7) ℃, 333 (279, 392) vs. 311 (259, 359) U/L, both P<0.05). Logistic regression showed the prediction probability π=exp (-29.7+0.667×Peak body temperature (℃)+0.004×LDH (U/L))/(1+exp (-29.7+0.667×Peak body temperature (℃)+0.004 × LDH (U/L))), the cut-off value to predict RMPP was 0.12, with a consensus of probability forecast of 0.89, sensitivity of 0.89, and specificity of 0.67; and the area under ROC curve was 0.682 (95%CI 0.593-0.771, P<0.01). Conclusion: In MPP patients with fever over 48 to <120 hours, a prediction probability π of RMPP can be calculated based on the peak body temperature and LDH level before the first visit, which can facilitate early identification of RMPP.

[Prevalence of medicare antiviral drugs use and related factors in HIV-infected people in Ningbo].

Objective: To analyze the use of medicare antiviral drugs (ART) and related factors among HIV-infected people in Ningbo City. Methods: The retrospective data was collected related to infection and treatment of HIV-infected people in ART in Ningbo up to February 2023 through the National Infectious Disease Surveillance System. Binary logistic regression was used to analyze the factors related to medicare antiviral drug use in HIV-infected people. R 4.2.2 software was used for statistical analysis. Results: A total of 6 433 HIV-infected people with ART records were collected, among which 5 783 were in ART. The prevalence of medicare drugs use among people in ART was 24.8% (1 435/5 783, 95%CI: 23.7%-25.9%). Beilun District (8.7%, 43/497) and Fenghua District (5.7%, 14/247) had the lowest level in medicare drugs use. Among people in ART using medicare or out-of-pocket drugs, the prevalence of those who had at least one viral load test in the last year (84.9%, 1 352/1 593) was significantly lower than that of those using free drugs (91.4%, 3 829/4 190) (χ2=52.50, P<0.001). The results of multivariate logistic analysis showed that the factors influencing medicare drug use included low educational level (junior high school and below: aOR=0.24, 95%CI:0.17-0.34), farmer or worker (farmer: aOR=0.60, 95%CI: 0.39-0.91; worker: aOR=0.42, 95%CI: 0.27-0.64), low monthly income (<3 000 Yuan: aOR=0.29, 95%CI: 0.18-0.45), the longer interval time between diagnosis and treatment (≥21 days: aOR=0.47, 95%CI: 0.30-0.74). Conclusions: Significant regional differences on the prevalence of medicare antiviral drugs use in HIV-infected people exist in Ningbo City. Follow-up management program of patients should be improved to strengthen patient compliance to mobilize medicare drug promotion. Meanwhile, publicity of medicare drugs should be strengthened for farmers or workers with low education level and patients with delayed treatment.

[Effect of calcium-independent phospholipase A2 on the expression of glycerol 3-phosphate dehydrogenase in human non-alcoholic fatty liver disease cells].

Objective: To explore the effect of calcium-independent phospholipase A2 (iPLA2) on the expression of mitochondrial glycerol 3-phosphate dehydrogenase (mGPDH) in human non-alcoholic fatty liver disease cells. Methods: Oleic acid was used to construct a non-alcoholic fatty liver disease cell model by inducing lipid deposition in THLE-2 cells in vitro. Simultaneously, intracellular triglyceride content, iPLA2 expression levels, and mGPDH levels were determined at various induction times (0, 24, 48, and 72 h) using a triglyceride assay kit, quantitative RT-PCR, and western blotting. The model cells were treated with bromelenol lactone, an iPLA2 inhibitor, and N-acetylcysteine, a ROS inhibitor, respectively. Following continuous culture for 24 and 48 hours, the cells were harvested, and the mRNA and protein expression levels of mGPDH were measured. Statistical analysis was performed using the t-test, one-way analysis of variance, and linear correlation. Results: The intracellular triglyceride content gradually increased (P < 0.01), the mGPDH mRNA and protein expression decreased (P < 0.01), and the iPLA2 mRNA and protein expression increased (P < 0.01) in THLE-2 cells with the prolonging time effect of oleic acid therapy. In addition, the mGPDH mRNA expression level was negatively correlated with the iPLA2 mRNA level (r = -0.878, P = 0.002). The expression levels of mGPDH mRNA and protein in the iPLA2 inhibitor group and ROS inhibitor group were increased compared with the model control group (P < 0.01). The expression of mGPDH mRNA was increased at 24 h compared with 48 h in the iPLA2 inhibitor group (P < 0.01). The expression of mGPDH mRNA was gradually increased in the ROS inhibitor group with the prolongation of inhibitor action time (P < 0.01). Compared with the two inhibitor groups, the increase in mGPDH mRNA was significantly higher in the ROS inhibitor group than that in the iPLA2 inhibitor group, and the difference was statistically significant (P < 0.01). Conclusion: iPLA2 can inhibit the expression of mGPDH in non-alcoholic fatty liver cells to a certain extent.

Prognostic value of multiphase CT angiography: estimated infarct core volume in the patients with acute ischaemic stroke after mechanical thrombectomy.

BACKGROUND AND PURPOSE: Recent studies reported the feasibility of quantifying a reliable infarct core (IC) volume using multiphase computed tomography (mCTA) based on deep learning, however its prognostic value was not fully clarified. Therefore, we aimed to evaluate the prognostic value of mCTA-estimated IC volume in patients with acute ischemic stroke (AIS) after mechanical thrombectomy (MT). MATERIALS AND METHODS: We retrospectively reviewed patients who underwent mCTA and MT for large vessel occlusion in middle cerebral artery and (or) internal carotid artery within 6 hours after symptom onset between January 2018 and November 2019. Patients were dichotomized into good (modified Rankin Scale [mRS] score, 0-2) and poor (mRS, 3-6) outcome groups. mCTA-estimated IC volume were generated based on a multi-scale three-dimensional convolutional neural network. Univariate, multivariate logistic regression and receiver operating characteristic (ROC) curve analyses were used to identify the independent variables, and evaluate their performances in predicting the clinical outcome. RESULTS: Of 44 included patients, 27 (61.4%) patients achieved good outcome. National Institutes of Health Stroke Scale scores at admission [NIHSSpre] (odds ratio [OR], 1.191; 95%confidence interval [CI], 1.028-1.379; P=0.020) and mCTA-estimated IC volume (OR, 1.076; 95%CI, 1.016-1.140; P=0.013) were found to be independently associated with functional outcome in patients with AIS after MT. After integrating NIHSSpre and mCTA-estimated IC volume, optimal performance (area under the ROC curve, 0.874; 95%CI, 0.739-0.954) could be obtained in predicting the clinical outcome. CONCLUSIONS: mCTA-estimated IC volume might be promising for predicting the prognosis, and assisting in making individualized treatment decision in patients with AIS.

[Quantitative analysis of lipid metabolism-related differential proteins in patients with alcoholic liver disease].

Objective: To screen and identify differential proteins, analyze lipid metabolism-related proteins and pathways, and explore their functions and biological processes in liver tissue of patients with alcoholic liver disease using tandem mass tag (TMT) labeling technology. Methods: Liver tissues that met the inclusion criteria were collected. Eight samples from patients with alcoholic cirrhosis and three samples from the normal control group were screened out. The TMT technique was used to screen differential proteins, perform signaling pathway enrichment analysis, and analyze protein interaction networks to explore the biological processes involved in them. Results: Proteomic analysis identified 2 741 kinds of differentially expressed proteins in the two groups of data with statistical significance (P < 0.05). The standard criteria of P < 0.05 and |log2(foldchange)| > 1 had screened out 106 kinds of differentially expressed proteins. Compared with the control group, the alcoholic liver disease group had 12 kinds of up-regulated proteins and 94 kinds of down-regulated proteins. Among them, there were 2 kinds of up-regulated differential proteins related to lipid metabolism and 14 kinds of down-regulated differential proteins. The results of bioinformatics analysis showed that these proteins were primarily involved in biological processes such as lipid transport, regulation of lipase activity, fatty acid binding, and cholesterol metabolism in lipid metabolism and also had a close link to signal pathways related to lipid metabolism such as peroxisome proliferator-activated receptor signaling pathways, cholesterol metabolism, triglyceride metabolism, and regulation of lipolysis in adipocytes. Conclusion: The 16 kinds of lipid metabolism-related differential proteins may be the key proteins in the pathogenesis of alcoholic liver disease.

Endovascular treatment for acute ischaemic stroke caused by isolated internal carotid artery occlusion: treatment strategies, outcomes, and prognostic factors.

AIM: To describe the experience of endovascular treatment (EVT) of acute ischaemic stroke caused by isolated internal carotid artery (ICA) occlusion, with emphasis on treatment strategies, outcomes, and prognostic factors. MATERIALS AND METHODS: A retrospective examination was performed of 66 consecutive patients with acute moderate-to-severe stroke who underwent EVT for isolated ICA occlusion from July 2016 to June 2021. The modified thrombolysis in cerebral ischaemia (mTICI) score was used to evaluate reperfusion outcomes. A multivariate analysis was performed to identify risk factors associated with poor 90-day outcome (modified Rankin Scale [mRS] 3-6). RESULTS: The National Institutes of Health Stroke Scale (NIHSS) median score of the 66 patients at admission was 15. Twelve patients (18.2%) showed thrombus migration to the M1 segment or proximal M2 during EVT and underwent additional intracranial thrombectomy. Successful reperfusion (mTICI 2b-3) was achieved in 60 patients (90.9%) and complete reperfusion (mTICI 3) in 42 (63.6%). A poor functional outcome was seen in 27 patients (40.9%). The rate of 90-day mortality was 9.1% (6/66). Higher NIHSS scores and a lower Alberta Stroke Program Early CT Score (ASPECTS) were independently associated with poor outcomes. Complete reperfusion was the only treatment factor with a significant predictive value (adjusted odds ratio [OR] 0.03; 95% CI = 0.01 to 0.25; p=0.001). CONCLUSION: Endovascular therapy is safe and effective in patients with acute ischaemic stroke due to isolated ICA occlusion. Prevention of thrombus migration and complete reperfusion should be the aim of EVT.

Endovascular Recanalization of Symptomatic Chronic ICA Occlusion: Procedural Outcomes and Radiologic Predictors.

BACKGROUND AND PURPOSE: Endovascular recanalization has been attempted in patients with symptomatic chronic ICA occlusion, however, the heterogeneity of recanalization outcomes and the perioperative complications present challenges for the clinical application. Our aim was to evaluate the safety and efficacy of endovascular recanalization for symptomatic chronic ICA occlusion and identify potential predictors for successful recanalization. MATERIALS AND METHODS: This study included 47 consecutive patients with symptomatic chronic ICA occlusion who underwent endovascular recanalization at our institution. Patients' clinical information, radiologic characteristics, procedural results, and outcomes were recorded. Factors related to technical success were analyzed by univariate and multivariate analyses. RESULTS: The technical success rate was 74.5% (35/47); 12.8% of patients (6/47) experienced intraoperative complications, but none had permanent neurologic deficits. Three months after recanalization, 21 of the 29 recanalized patients (72.4%) and 3 of the 10 failed patients (30.0%) demonstrated improved mRS scores. Restenosis or re-occlusion occurred in 12.9% of patients (4/31) with successful recanalization. Multivariate analysis showed that tapered or blunt stump (P = .016), distal ICA occlusion segment (below the cavernous segment versus at or above the ophthalmic segment, P = .003; at the cavernous or clinoid segment versus at or above the ophthalmic segment, P = .027), and radiologic occlusion to recanalization of ≤3 months (P = .044) were significantly associated with successful recanalization. Patients were assigned points according to the coefficients of the prediction model, and the technical success rates were 0%, 46.2%, 90.5%, and 100% in patients with 1, 2, 3, and 4 points, respectively. CONCLUSIONS: Endovascular recanalization is a safe and effective treatment for symptomatic chronic ICA occlusion in selected patients. A residual stump, low levels of the distal ICA occlusion segment, and a short radiologic occlusion time were identified as positive predictors of technical success.

Association between Infarct Location and Hemorrhagic Transformation of Acute Ischemic Stroke following Successful Recanalization after Mechanical Thrombectomy.

BACKGROUND AND PURPOSE: The association between infarct location and hemorrhagic transformation of acute ischemic stroke after mechanical thrombectomy is not understood. We aimed to evaluate the association between CTP-based ischemic core variables at admission and hemorrhagic transformation after a successful thrombectomy. MATERIALS AND METHODS: We retrospectively analyzed patients who underwent endovascular thrombectomy for acute anterior circulation large-vessel occlusion between October 2019 and June 2021. We enrolled 146 patients with visible ischemic core on pretreatment CTP who had successful reperfusion. The ischemic core infarct territories were classified into the cortical and subcortical areas and then qualitatively and quantitatively analyzed by CTP. Logistic regression and receiver operating characteristic curve analyses were performed to determine the association between ischemic core variables and hemorrhagic transformation. RESULTS: Of the 146 patients analyzed, 72 (49.3%) had hemorrhagic transformation and 23 (15.8%) had symptomatic intracerebral hemorrhage. Multivariate analysis showed that subcortical infarcts were independently associated with hemorrhagic transformation (OR, 8.06; 95% CI, 2.31-28.10; P = .001) and subcortical infarct volume was independently linked to symptomatic intracerebral hemorrhage (OR, 1.05; 95% CI, 1.01-1.09; P = .039). The receiver operating characteristic curve indicated that subcortical infarcts can predict hemorrhagic transformation accurately (area under the curve = 0.755; 95% CI, 0.68-0.82; P < .001) and subcortical infarct volume can predict symptomatic intracerebral hemorrhage (area under the curve = 0.694; 95% CI, 0.61-0.77; P = .002). CONCLUSIONS: Subcortical infarcts seen on CTP at admission are associated with hemorrhagic transformation in patients after successful thrombectomy, and subcortical infarct volume may influence the risk of symptomatic intracerebral hemorrhage.

Automated Estimation of Quantitative Lesion Water Uptake as a Prognostic Biomarker for Patients with Ischemic Stroke and Large-Vessel Occlusion.

BACKGROUND AND PURPOSE: Net water uptake is qualified as an imaging marker of brain edema. We aimed to investigate the ability of net water uptake to predict 90-day functional outcome in patients with acute ischemic stroke and large-vessel occlusion. MATERIALS AND METHODS: A total of 295 consecutive patients were retrospectively enrolled. Automated ASPECTS-net water uptake was calculated on the admission CT. The relationship between ASPECTS-net water uptake and 90-day neurologic outcome was assessed. The independent predictors of favorable outcome (mRS score ≤2) were assessed using multivariate logistic regression analysis and receiver operating characteristic curves and stratified by the ASPECTS. RESULTS: Favorable 90-day outcomes were observed in 156 (52.9%) patients. ASPECTS-net water uptake (OR, 0.79; 95% CI, 0.70-0.90), NIHSS scores (OR, 0.91; 95% CI, 0.87-0.96), age (OR, 0.96; 95% CI, 0.94-0.99), and vessel recanalization (OR, 7.78; 95% CI, 3.96-15.29) were independently associated with favorable outcomes at 90 days (all, P < .01). A lower ASPECTS-net water uptake independently predicted a good prognosis, even in the subgroup of patients with low ASPECTS (≤5) (P < .05). An outcome-prediction model based on these variables yielded an area under the receiver operating characteristic curve of 0.856 (95% CI, 0.814-0.899; sensitivity, 76.3%; specificity, 81.3%). CONCLUSIONS: ASPECTS-net water uptake could independently predict 90-day neurologic outcomes in patients with acute ischemic stroke and large-vessel occlusion. Integrating ASPECTS-net water uptake with clinical models could improve the efficiency of outcome stratification.

[Cost-effectiveness prediction of AIDS interventions among men who have sex with men in Ningbo].

Objective: To provide information reference for resource allocation and decision-making in related fields, the cost-effectiveness of HIV input among men who have sex with men (MSM) in Ningbo. Different intervention coverages were compared. Methods: Taking MSM as the target population, data were collected and modeled by Optima HIV for the corresponding HIV health output and the budget under different intervention coverages. Results: According to the estimated size of the MSM population, which was 19 584 in Ningbo in 2020, if the coverage of 2020 baseline intervention is maintained in the next ten years, the number of HIV cases, new HIV infections, and HIV-related deaths among this population will show an upward trend. It is estimated that from 2021 to 2030, 7.9% of new infections and 1.7% of deaths can be avoided and the relevant funding investment comed to 2.4 time the baseline if the intervention coverage rate expanded to 3.0 times the 2020 baseline. After the coverage rate of intervention expanded to 3 times the baseline, it continued to grow, the health effect did not increase. Conclusions: At present, expanding the baseline coverage of HIV-related intervention projects among MSM in Ningbo and increasing capital investment will still reverse HIV-related death and reduce new infections. Moreover, there is a saturation point of the intervention effect. Researchers and policymakers must explore more effective interventions/combinations to obtain more significant health outcomes.

[Status of HVPG clinical application in China in 2021].

Objective: The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China. Methods: This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems. Results: According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%). Conclusion: Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Acute embolic stroke with large-vessel occlusion: does contact aspiration thrombectomy show superiority?

AIM: To compare the efficacy between contact aspiration thrombectomy and stent retriever thrombectomy in the treatment of acute embolic stroke patients with large vessel occlusion. MATERIALS AND METHODS: Between January 2019 and June 2020, data from consecutive acute ischaemic stroke patients who underwent either endovascular contact aspiration or stent retriever thrombectomy were analysed at one institution. The primary outcome was the full 90-day modified Rankin Scale (mRS) score. Ordinal logistic regression analysis was used to assess the association between thrombectomy approach and functional outcomes. RESULTS: A total of 156 patients were analysed. Among them, 57 (36.5%) patients underwent primary aspiration thrombectomy, while 99 (63.5%) patients underwent primary stent retriever thrombectomy. The median procedure time was significantly shorter in patients treated with aspiration (37 versus 56 minutes; p<0.001). Compared with those of patients who underwent stent retriever thrombectomy, successful recanalisation rates and favourable functional outcome rates were higher in patients who underwent the aspiration approach (94.7% versus 77.8%, p=0.006; 49.1% versus 27.3%, p=0.006, respectively). Ordinal logistic regression analysis showed that aspiration thrombectomy was independently associated with a good functional outcome (adjusted common odds ratio, 0.30, 95% confidence interval: 0.16-0.60, p<0.001). CONCLUSION: Among the specific patients with large vessel occlusion in acute embolic stroke, the use of aspiration thrombectomy compared with stent retriever thrombectomy resulted in a greater likelihood of favourable neurological outcomes; however, because of study limitations, these findings should be interpreted as preliminary and require further study to confirm these results.

Hypoperfusion intensity ratio correlates with clinical outcome of endovascular thrombectomy in acute ischaemic stroke patients with late therapeutic window.

AIM: To evaluate the prognostic value of the hypoperfusion intensity ratio (HIR) on 90-day clinical outcome in acute ischaemic stroke (AIS) patients with late therapeutic window. MATERIALS AND METHODS: One hundred and sixty-eight consecutive AIS patients with anterior-circulation large-vessel occlusion who underwent endovascular thrombectomy during the late window were enrolled retrospectively. Clinical data, Alberta Stroke Program Early Computed Tomography Score (ASPECTS) based on unenhanced computed tomography (CT), and perfusion parameters included ischaemic core, hypoperfusion volume, mismatch volume between core and penumbra, and the HIR were assessed and compared between patients with or without favourable outcomes (defined as modified Rankin Scale score of 0-2). Statistical analysis included binary logistic regression and receiver operating characteristic (ROC) analyses. RESULTS: A favourable outcome was achieved in 76 (45.2%) patients. In univariable analysis, age, National Institutes of Health Stroke Scale (NIHSS) score at admission, ASPECTS score, HIR, ischaemic core, and hypoperfusion volume were significantly associated with functional outcome (p<0.05). In multivariate analyses, age (OR 0.95; 95% CI 0.92-0.99), NIHSS score at admission (OR 0.89, 95% CI 0.84-0.96) and HIR (OR 0.018, 95% CI 0.003-0.113) remained as independent outcome predictors (p<0.01). The optimal threshold of HIR was 0.36 (sensitivity 70.7%, specificity 61.8%). The combination of age, NIHSS score at admission, and HIR yield good performance for outcome prediction with an area under the ROC curve of 0.815 (sensitivity 88.2%, specificity 64.1%), significantly higher than individual variable (p<0.05). CONCLUSION: Low HIR was a predictor for favourable outcome in AIS patients with late therapeutic window. Integrating HIR with clinical variables improved the ability for outcome classification.

[Role of lymphocytes in the pathogenesis of autoimmune hepatitis].

In recent years, the number of autoimmune hepatitis cases in the world has shown a significant upward trend, but its etiology and pathogenesis is still unclear. At present, it is generally considered to be caused by abnormal immune regulation mechanism of the body, especially the lymphocytes and their cytokines, which has attracted widespread concern and thus is reviewed here.

Non-negligible clinical relevance of haemorrhagic transformation after endovascular thrombectomy with successful reperfusion in acute ischaemic stroke.

AIM: To explore the association between haemorrhagic transformation (HT) subtypes and functional outcome in acute ischaemic stroke (AIS) patients with successful recanalization treated by endovascular thrombectomy (EVT). MATERIALS AND METHODS: Consecutive patients with AIS due to large-vessel occlusion in the anterior circulation, who were treated between January 2015 and June 2019 and achieved successful EVT, were enrolled in this retrospective study. HT was categorized according to the Heidelberg Bleeding Classification. Functional outcome was evaluated using the 90-day modified Rankin Scale (mRS) after stroke onset. Ordinal logistic regression analysis was performed to determine the association of HT subtypes with functional outcomes. RESULTS: A total of 243 patients were included for further analysis. Among them, 121 (49.8%) had HT. Ten (4.1%) patients were classified as haemorrhagic infarction (HI) subtype 1, 61 (25.1%) as HI subtype 2, 17 (7.0%) as parenchymal haematoma (PH) subtype 1, and 33 (13.6%) as PH subtype 2. Ordinal logistic regression analysis suggested that HI subtype 2 (adjusted common OR 0.357, 95% CI: 0.192-0.667), PH1 (adjusted common OR 0.254, 95% CI: 0.093-0.696) and PH subtype 2 (adjusted common OR 0.017, 95% CI: 0.006-0.051) were significantly associated with poor functional outcomes. CONCLUSION: The present study shows that HI subtype 2, PH subtype 1, and PH subtype 2 are independently associated with poor clinical outcomes in AIS patients with successful recanalization after EVT.

[HIV infection and related factors of traceability efficiency among sex partners of HIV positive men who have sex with men].

Objective: To investigate the situation related to HIV infection and influencing factors of traceability efficiency among sex partners of HIV positive men who have sex with men (MSM). Methods: A cross-sectional survey was conducted to investigate the traceability among sex partners of HIV-positive MSM in Ningbo from 2018 to 2020. Limiting-antigen avidity enzyme immunoassay determined recent HIV infection. The classified data was evaluated by chi-square test, and factors of traceability efficiency were analyzed by multivariate logistic regression. Results: A total of 374 newly confirmed HIV-positive MSM were recruited to participate in the HIV test in Ningbo from 2018 to 2020.HIV positive rate of sex partner was 15.7% (75/479,95%CI:12.4%-18.9%). HIV positive rates of sex partner of recent HIV infection MSM was 31.8% (21/66,95%CI:20.3%-43.4%). The proportion of newly confirmed HIV-positive sex partners of recent HIV infection MSM (76.2%) was higher than that of long-term HIV infection MSM (48.1%). The difference was statistically significant (P=0.028). Results from the multivariate logistic regression analysis showed that HIV traceability efficiency was higher in the following subpopulations as; HIV positive MSM who were 36-45 years old (compared with 18-25 years old, OR=3.973,95%CI:1.364-11.569), HIV active detection (compared with HIV passive detection, OR=1.896, 95%CI:1.083-3.319), recent HIV infection MSM (compared with long-term HIV infection MSM, OR=3.733, 95%CI:1.844-7.556). Conclusions: HIV positive rate among partners of HIV positive MSM was very high. The traceability efficiency, which was recent HIV infection MSM and HIV active detection, was high. It is suggested to strengthen the traceability and focus on the newly confirmed HIV-positive MSM in VCT clinics.

[Characteristics and influencing factors of newly HIV infection among newly confirmed HIV/AIDS cases in Ningbo city, 2017-2020].

Objective: To identify the characteristics and influencing factors of local HIV infection among newly confirmed cases in Ningbo from 2017 to 2020 to provide evidence for traceability investigations on critical cases and facilitate the detection procedures and reduce new HIV infection. Methods: From January 1, 2017, to December 31, 2020, the newly confirmed HIV/AIDS in Ningbo were recruited. An epidemiological questionnaire was used to collect relevant information, including demography, sexual behaviors, results of HIV antibody tests, and the route of HIV transmission. According to the HIV testing, history of risk behaviors, and the level of CD4+ lymphocytes after confirmation, the HIV infection was acquired in the previous year, or the place was in Ningbo. The EpiData 3.1 and SPSS 23.0 software were used for input, sorting database and statistical analysis. Results: A total of 2 044 HIV/AIDS on-site investigations were completed. The average age of the subjects was (40.6±15.3) years old, including 1 684 males (82.4%), 758 unmarrieds (37.1%), 1 072 (52.5%) registered as permanent residents in Ningbo, 1 253 (61.3%) with junior high school education or below, 979 (47.9%) lived in Ningbo for more than five years. The proportion of local, new HIV infections was 34.34% (702/2 044). Multivariate logistic analysis showed that the proportion of local newly HIV infection was higher among those who were confirmed in 2020 (compared with the 2017 confirmed cases, OR=1.422, 95%CI:1.092-1.851), whose occupations were students/teachers/cadres/retirees (compared to commercial service/catering/public place service personnel, OR=1.682, 95%CI: 1.307-2.165), meeting sex partners via male social software locally in the last year (compared with without using related dating software, OR=1.353, 95%CI: 1.073-1.706). Conclusions: The proportion of local HIV infection of newly confirmed HIV/AIDS was relatively high in Ningbo city from 2017 to 2020. Meeting gay sex partners through local male social software appeared a risk factor for local newly HIV infection. Traceability investigations and internet intervention should be carried out for MSM. While male social software should be focused on identifying and controlling the risk of local newly HIV infection.

[Efficacy evaluation of vestibular rehabilitation based on mobile internet in patients with otogenic vertigo].

Twenty-five patients diagnosed with otogenic vertigo at the outpatient clinic of the Department of Otolaryngology-Head and Neck Surgery, Shanghai Jiao Tong University Affiliated Sixth People's Hospital from January to June 2020 were selected. Among them, 8 cases were male and 17 cases were female, aged (48±13) years. All the patients underwent internet combined with offline follow-up vestibular rehabilitation for 12 weeks, which included vestibulo-ocular reflex exercises, proprioceptive exercises and static/dynamic balance exercises. Computerized dynamic posturography (CDP) and dizziness handicap inventory (DHI) scores were compared before and after rehabilitation. The DHI score improved significantly after 12 weeks of vestibular rehabilitation (48.3±15.9 vs 26.7±17.9, t=5.319, P<0.001). Meanwhile, the sensory organization test (SOT) score was also improved (73.3±8.1 vs 76.1±6.6, t=2.066, P=0.050), while the difference of motor control test (MCT) latent stage score before and after rehabilitation was not statistically significant (140±13 vs 141±16, t=0.791, P=0.436). The current study demonstrates that vestibular rehabilitation based on mobile internet is convenient, economical and effective, and patients can benefit from it.

[Expression and clinicopathological significance of Bcl - 2 and Bax genes in colorectal cancer patients complicated with schistosomiasis].

OBJECTIVE: To investigate the expression and clinicopathological significance of Bcl-2 and Bax genes in colorectal cancer (CRC) patients complicated with schistosomiasis. METHODS: The CRC patients receiving surgical treatment in the First Affiliated Hospital of Dali University from June 2016 to June 2020 were recruited as the study subjects, and 30 subjects were randomly sampled from the CRC patients complicated with schistosomiasis (CRC-S group) and 30 subjects were randomly sampled from the CRC patients without schistosomiasis (CRC group) using a random number table method. The cancer specimens were sampled from subjects in the CRC-S and CRC groups, and the peri-cancer specimens were sampled from subjects in the CRC group. The Bcl-2 and Bax expression was quantified in cancer and peri-cancer specimens using a real-time fluorescent quantitative PCR (qPCR) assay and immunohistochemistry at transcriptional and translational levels, and the cell apoptosis was detected in cancer specimens using HE staining. RESULTS: A total of 60 subjects were enrolled, including 30 cases in the CRC group and 30 cases in the CRC-S group. There were no significant differences between the two groups in terms of gender distribution (χ2 = 0.271, P > 0.05), mean age (t = -0.596, P > 0.05), tumor growth pattern (χ2 = 0.275, P > 0.05), tumor location (χ2 = 4.008, P > 0.05), tumor invasion depth (χ2 = 0.608, P > 0.05), degree of tumor differentiation (χ2 = 0.364, P > 0.05), or presence of vascular metastasis (χ2 = 1.111, P > 0.05), while significant differences were seen between the two groups in terms of histological type, presence of lymph node metastasis and TMN staging (χ2 = 5.963, 8.297 and 5.711, all P values < 0.05). qPCR assay and immunohistochemistry quantified significantly higher Bcl-2 and Bax expression in cancer specimens from the CRC and CRC-S groups than in the peri-cancer specimens from the CRC group at both translational and transcriptional levels (all P values < 0.05), and higher Bcl-2 and lower Bax expression were seen in the cancer specimens from the CSC-S group than that from the CRC group (all P values < 0.05). In addition, the cell apoptotic rate was significantly greater in the cancer specimens in the CRC group than in the CRC-S group (42.00% vs. 23.35%; χ2 = 41.500, P = 0.000). CONCLUSION: Schistosomiasis may be involved in the development and progression of CRC through affecting Bcl-2 and Bax gene expression in the apoptosis signaling pathway.
