Abstract: Objective　To investigate the fundus arteriosclerosis and its influencing factors in HIV/AIDS patients after long-term highly active antiretroviral therapy (HAART). Methods　The clinical basic data and fundus examination data of 203 HIV/AIDS patients before and after HAART in the Fourth People 's Hospital of Nanning from January 2020 to June 2022 were collected to evaluate the occurrence of fundus arteriosclerosis and analyze its influencing factors. Results　Of the 203 HIV/AIDS patients, 159 patients developed fundus arteriosclerosis, with an incidence of 78.33%, including 33 patients with grade Ⅰ(20.75%), 87 patients with grade Ⅱ (54.72%), 28 patients with grade Ⅲ(17.61%), and 11 patients (6.92%) with Grade Ⅳ. Before HAART, there was no significant difference in CD4+T lymphocyte count, CD8+T lymphocyte count, viral load, white blood cell count, platelet count, hemoglobin, serum creatinine, blood urea nitrogen, triacylglycerol, total cholesterol, fasting blood glucose, alanine aminotransferase, aspartate aminotransferase and serum total bilirubin between the atherosclerosis group and normal group (P>0.05). After 6 months of HAART, CD8+T lymphocyte count, triacylglycerol and fasting blood glucose in atherosclerosis group were significantly higher than those in normal group (P<0.05). In the stratified comparison of CD4+ and CD8+ lymphocyte counts after 6 months of HAART, the proportion of patients with CD4+ lymphocyte count (CD4+)<200 (cells/μL) in the atherosclerosis group was significantly higher than that in the normal group; the proportion of patients with CD4+ lymphocyte count (CD4+)≥500 (cells/μL) was significantly lower than that in the normal group; the proportion of patients with CD8+ lymphocyte count CD8+≥ 800/μL was significantly higher than that in the normal group (all P<0.05). Binary logistic regression analysis showed that opportunistic infection, HIV course, CD4+T, CD8+T lymphocyte count after HAART and triglyceride were independent risk factors for ocular fundus atherosclerosis in HIV/AIDS patients (all P<0.05). Conclusions　The incidence of ocular fundus arteriosclerosis is high in HIV/AIDS patients. More than 4 years of HIV course, combined opportunistic infection, Low CD4+T lymphocyte count after 6 months of HAART, high CD8+T lymphocyte count and high triglyceride level are independent risk factors for ocular fundus arteriosclerosis in HIV/AIDS patients. Fundus screening should be performed before and after HAART in such population, HAART program should be formulated for the risk of cardiovascular disease, and risk management of cardiovascular disease should be strengthened during treatment to improve patient outcomes.

Objective To establish a novel TRFIA for the measurement of heparanase (HPA) in serum samples,and investigate its clinical application.Methods The micro-pore plate wells were first coated with partially recombinant murine anti-human HPA monoclonal antibody.Biotin-labeled recombinant HPA protein was then used to compete with HPA in serum samples,and the prepared europium (III)-labeled streptavidin (Eu3+-SA) was used as signal readout for establishing the BSA-TRFIA assay.Using this assay,the serum HPA levels in healthy subjects (n=32) and tumor patients (n=54) were measured.The results of BSA-TRFIA were compared with those of ELISA.Two-sample t test (or t' test),and linear correlation analysis were used to analyze the data.Results The sensitivity of BSA-TRFIA for measuring HPA was 0.33 ug/L.The CV values for intra-batch and inter-batch were 5.29% and 7.54%,respectively.The average recovery rate was 105.5%.The standard curve range was 0-1 000 ug/L.The serum HPA level measured by the BSA-TRFIA method in healthy subjects was (2.03_+ 1.47) Iug/L.In tumor patients,the HPA level was significantly higher:(22.13_+7.38) ug/L (t'=19.388,P

Objective This study was undertaken to examine possible relationship between attempted suicide and underachievement,bullying,low life satisfaction and low self-concept at school.Methods An anonymous self-report survey assessing demographic characteristics and the major risk factors of teenage attempted suicide was completed by students from 16 middle schools in grades seven to twelve in 4 counties of Anhui province (age 10 to 21 years).An anonymous questionnaire was used to rate attempted suicide,bullying involvement and learning performance.Attempted suicide was defined as: experiencing specific suicide actions at least one time during the 12 months preceding the survey.Multidimensional Students' Life Satisfaction Scale and Children' s Self-concept Scale were used to evaluate satisfaction and self-conscience on and at respectively.In total,10 894 respondents substantially completed the survey.Multiple logistic-regression analyses,controlling for socio-demographic variables,was used to analyze if underachievement,bullying,low school life satisfaction and low children' s self-conscience at school had been risk factors.Results 629 participants (5.8%) reported having made at least one attempted suicide within the last 12 months.Students being underachieved were significantly having more attempted suicide events than those excellent students (X2=11.39,P=0.023).Students being both bully-victims and practiced bully were significantly more than those being only practiced bully (28.7% vs.15.8%,P＜0.001),being victims (28.7% vs.10.6%,P＜0.001) or having neither of them (28.7% vs.4.8%,P＜0.001).Results from multiple logistic regression analyses showed that underachievement,bullying,lower school life satisfaction and low self-conscience were risk factors for attempted suicide.Conclusion Data from this study confirmed that school bullying and children' s self-conscience at school were significantly associated with attempted suicide among rural middle school students in Anhui province.It is of importance to improve the school' s environments to reduce the risk of attempted suicide among this group.

Objective To explore the timing and technical points in treating intracranial aneurysms with endovascular embolization, and analyze its efficacy and the prevention of its complications. Methods Thirty-eight patients with intracranial aneurysm, admitted to our hospital from February 2006 to January 2009, were treated by endovascular embolism with the help of digital subtraction angiography (DSA). Twenty-six patients (27 aneurysms) were performed embolization with mechanical detachable coils (MDC) and 12 patients (12 aneurysms) were performed embolization with Guglielmi detachable coils (GDC). Their clinical data and efficacy were analyzed. Results Thirty-eight cases (39 aneurysms) were successfully embolized: 32 cases (84.2%) were fully embolized; 4 cases (10.5%) were 95% embolized and 2 cases (5.26%) were 90% embolized. Internal carotid artery thrombosis was found in 1 with wild-necked aneurysms after embolism and the patient was found hemiplegia and aphasia after 3 months. Bleeding caused by aneurysm rapture occurred in 2 and recovered after treatment Follow-up showed that 37 patients were successfully recovered except that 1 elderly patient died of lung infection and gastrointestinal bleeding. Conclusion Endovascular embolization, a minimally invasive, safe and effective technique, can effectively treat most patients with intracranial aneurysms.

BACKGROUNDHypertension is a complex biological trait that influenced by multiple factors. The encouraging results for hypertension research showed that the linkage analysis can be used to replicate other studies and discover new genetic risk factors. Previous studies linked human chromosome 14 to essential hypertension or blood pressure traits. With a Chinese population, we tried to replicate these findings.

METHODSA linkage scan was performed on chromosome 14 with 14-microsatellite markers with a density of about 10 centi Morgen (cM) in 147 Chinese hypertensive nuclear families. Multipoint non-parametric linkage analysis and exclusion mapping were performed with the GENEHUNTER software, whereas quantitative analysis was performed with the variance component method integrated in the SOLAR package.

RESULTSIn the qualitative analysis, the highest non-parametric linkage score is 1.0 (P = 0.14) at D14S261 in the single point analysis, and no loci achieved non-parametric linkage score more than 1.0 in the multipoint analysis. Maximum-likelihood mapping showed no significant results, either. Subsequently the traditional exclusion criteria of the log-of-the-odds score-2 were adopted, and the chromosome 14 with lambda s > or = 2.4 was excluded. In the quantitative analysis of blood pressure with the SOLAR software, two-point analysis and multipoint analysis suggested no evidence for linkage occurred on chromosome 14 for systolic and diastolic blood pressure.

CONCLUSIONThere was no substantial evidence to support the linkage of chromosome 14 and essential hypertension or blood pressure trait in Chinese hypertensive subjects in this study.

BACKGROUNDThere are many candidate genes for chronic obstructive pulmonary disease (COPD). Matrix metalloproteinase-9 (MMP-9) plays an essential role in tissue remodeling and repair associated with development of COPD. In this study we investigated the correlation between MMP-9 gene polymorphism and COPD susceptibility in the Han population of South China.

METHODSWe examined the frequency of polymorphic genotypes of the MMP-9 promoter (-1562C/T) in 100 COPD patients and 98 healthy smokers by restriction fragment length polymorphism.

RESULTSThe frequencies of polymorphic genotypes in promoters of MMP-9 were C/C 86%, C/T 14% in COPD group; and C/C 98%, C/T 2% in the control group. There were significant differences between the two groups (P < 0.01). The allele frequencies were also significantly different between the COPD group and the control group (C allele frequency: 93% vs 99%, T allele frequency: 7% vs 1%, P < 0.05 respectively).

CONCLUSIONThe genetic polymorphism in promoters of MMP-9 gene is associated with the susceptibility to COPD in the Han population of South China.

Objective: The present study was designed to evaluate the protective effects of oligomeric proanthocyanidins (OPC) in mice exposed to paraquat (PQ) , and to explore the molecular mechanism. Methods: Four experimental groups were designed. Control group: 10 BALB/c mice were intraperitoneally injected with normal saline) . PQ group: 10 BALB/c mice were intraperitoneally injected with PQ (100 mg/kg) . PQ+OPC group: 10 BALB/c mice were administered with OPC (100 mg/kg) for 1 h before PQ (100 mg/kg) expo-sure. OPC group: 10 BALB/c mice were intraperitoneally injected with OPC (100 mg/kg) . The peripheral blood samples or lung tissue samples were collected at the designed time points for measuring the levels of oxi-dative stress indicators, the related protein levels of nuclear factor-kappa B (NF-κB) pathway and nuclear fac-tor erythroid related factor-2 (Nrf2) pathway. Results: Compared with the control group, the level of reactive oxygen species (ROS) , the content of malondialdehyde (MDA) in the PQ group were significantly induced, and the activity of superoxide dismutase (SOD) in the PQ group was decreased in the peripheral blood. As com-pared with the PQ group, the level of ROS and the content of MDA in the PQ+OPC group were significantly re-duced, the activity SOD in the PQ+OPC group was increased in the peripheral blood; the level of ROS and the content of MDA were also reduced in lung tissues in the PQ+OPC group. Moreover, compared with the con-trol group, the phosphorylation of IκBα and the expression of NF-κB p65 were increased in lung tissues in the PQ group. The phosphorylation of IκBα and the expression of NF-κB p65 were decreased in lung tissues in the PQ+OPC group as compared with the PQ group. In addition, compared with the control group, the expressions of HO-1 and Nrf2 were increased in lung tissues in OPC group, and these were decreased in lung tissues in PQ groups. Furthermore, the expressions of HO-1 and Nrf2 were also increased in lung tissues in PQ+OPC as com-pared with the PQ group. Conclusion OPC could alleviate PQ-induced systemic toxicity in mice by regulating oxidative stress via NF-κB and Nrf2 pathway.
