ObjectiveTo investigate the prevalence rate of chronic non-communicable diseases （NCDs） and the association with quality of life in middle-aged and elderly patients with HIV/AIDS. MethodsThis cross-sectional study surveyed 432 patients with HIV/AIDS （aged≥45 years） in the Infectious Disease Center in Guangzhou Eighth People’s Hospital of Guangzhou Medical University， and 366 participants were included in the analysis after quality control. A questionnaire and the EuroQol 5-Dimensional 3-level version （EQ-5D-3L） were used to investigate NCDs and quality of life and Tobit regression model was used to estimate the association between chronic diseases and quality of life. ResultsAmong the 366 participants， 29（7.9%） had cardiovascular disease， 45（12.3%） had hypertension， 122（33.3%） had hyperglycemia， 151（41.3%）had hyperlipidemia，7（1.9%） had cancer， 17 （4.6%） had chronic kidney disease， 38 （10.4%） had chronic liver disease， 21（5.7%） had musculoskeletal disorders， and 253（69.1%） suffered from at least one type of chronic diseases. The median （lower and upper quartiles） of EQ-5D utility index was 1.000（0.964~1.000）. Multivariate Tobit regression results of the total population showed that cancer ［b_a=-0.08，95%CI （-0.15，-0.01），P=0.036］， chronic kidney disease ［b_a=-0.07， 95%CI （-0.12，-0.02），P=0.006］， musculoskeletal disease ［b_a=-0.09， 95%CI （-0.13， -0.05），P<0.001］， and ≥3 types of chronic diseases［b_a=-0.05， 95%CI（-0.08，-0.01），P=0.013］ were negatively correlated with EQ-5D utility index. The stratified analysis results of different CD4+T cell levels showed that hypertension ［b_a=-0.07， 95%CI （-0.12， -0.02）， P=0.007］， chronic kidney disease ［b_a=-0.10，95%CI （-0.18，-0.03）， P=0.006］， musculoskeletal disease ［b_a=-0.15， 95%CI （-0.22，-0.07）， P<0.001］ and ≥3 types of chronic diseases ［b_a=-0.09， 95%CI （-0.09， -0.01）， P<0.001］ were negatively correlated with EQ-5D utility index in the group with CD4≤500 （cells/μL）， whereas cancer［b_a=-0.11， 95%CI （-0.20，-0.01）， P=0.031］ was negatively correlated with EQ-5D utility index in the group with CD4＞500（cells/μL）. ConclusionsThe prevalence rate of chronic non-communicable diseases in middle-aged and elderly patients with HIV/AIDS is relatively high. The classification of NCDs such as cancer or chronic kidney disease or other chronic diseases and the numbers of NCDs categories are negatively correlated with quality of life. However，this association varies among patients with HIV/AIDS of different CD4+T cell levels. It is suggested that we should try to prevent and identify NCDs at an early stage， strengthen linkages and integration of health services for AIDS and chronic NCDs， and jointly manage and control AIDS with chronic diseases to improve the quality of life among people living with HIV/AIDS.

Objective:Evaluate the safety of the bioresorbable scaffold (BRS) series implanted.Methods:This is a cohort study, which included 377 patients with acute coronary syndrome (ACS) who underwent elective percutaneous coronary intervention (PCI) with Neovas-BRS implantation from July 2019 to April 2022 at the Northern Command General Hospital. The patients were divided into the series BRS group ( n=63) and single BRS group ( n=314). We compared PCI related data between two groups, as well as all-cause death, cardiac death, non-fatal myocardial infarction, target vessel revascularization, stroke, and bleeding of type 2 to 5 defined by the Bleeding Academic Research Consortium of America (BARC) during follow-up. We also compared the major adverse cardiovascular and cerebrovascular events (MACCE), which includes all-cause death, non-fatal myocardial infarction, target vessel revascularization and stroke, as well as the net adverse clinical events (NACE), which includes MACCE and bleeding of BARC type 2 to 5. Procedural immediate success was defined as a residual stenosis of<20% with successful stent implantation and post-PCI target vessel flow grade up to TIMI 3. The images of 11 patients in the series BRS group who underwent optical coherence tomography (OCT) were analyzed. Results:A total of 377 patients were finally enrolled, aged (52.5±10.7) years, including 80.4% (303/377) males . The immediate success rate of PCI was 100% in both groups. The number of ≥50% stenotic lesions, number of target vessels, SYNTAX score, number of post-application expansion balloons, number of guidewires, total stent length, contrast volume and operation time were higher in the series BRS group than in the single BRS group (all P<0.05). There was no significant difference in the proportion of intravascular ultrasound and OCT application between the two groups. One patient in the single BRS group had an ischemic stroke during postoperative hospitalization, but there were no death, non-fatal myocardial infarction, target vessel revascularization, or BARC 2 to 5 bleeding events occurred during hospitalization in both groups. Follow up time was 352.0 (193.0, 421.0) days. There was no statistically significant difference between the two groups in the incidence of all-cause death (0 vs. 0.6% (2/314), P=1.000), cardiogenic death (0 vs. 0.3% (1/314), P=1.000), nonfatal myocardial infarction (0 vs. 1.0% (3/314), P=1.000), target lesion revascularization (3.2% (2/63) vs. 1.6% (5/314), P=0.736), BARC type 2 to 5 bleeding (3.2% (2/63) vs. 5.7% (18/314), P=0.604), MACCE (3.2% (2/63) vs. 2.9% (9/314), P=0.894), and NACE (6.3% (4/63) vs. 8.6% (27/314), P=0.553) during the follow-up period. OCT results of the 11 (17.5%) patients in the series BRS group indicated that 3 patients (27.3%) achieved non-overlapping connection, and the immediate stent expansion rate was (95.47±0.04) %. In 8 patients with BRS overlapping connections, immediate stent expansion rate was (90.32±0.44) %. Conclusion:In patients with low to intermediate-risk ACS, serial implantation of RBS in long coronary lesions is safe and feasible, and achieves the similar short-term outcomes as single BRS implantation.

BACKGROUND: Intensive phototherapy (IPT) and exchange transfusion (ET) are the main treatments for extreme hyperbilirubinemia. However, there is no reliable evidence on determining the thresholds for these treatments. This multicenter study compared the effectiveness and complications of IPT and ET in the treatment of extreme hyperbilirubinemia. METHODS: This retrospective cohort study was conducted in seven centers from January 2015 to January 2018. Patients with extreme hyperbilirubinemia that met the criteria of ET were included. Patients were divided into three subgroups (low-, medium-, and high- risk) according to gestational week and risk factors. Propensity score matching (PSM) was performed to balance the data before treatment. Study outcomes included the development of bilirubin encephalopathy, duration of hospitalization, expenses, and complications. Mortality, auditory complications, seizures, enamel dysplasia, ocular motility disorders, athetosis, motor, and language development were evaluated during follow-up at age of 3 years. RESULTS: A total of 1164 patients were included in this study. After PSM, 296 patients in the IPT only group and 296 patients in the IPT plus ET group were further divided into the low-, medium-, and high-risk subgroups with 188, 364, and 40 matched patients, respectively. No significant differences were found between the IPT only and IPT plus ET groups in terms of morbidity, complications, and sequelae. Hospitalization duration and expenses were lower in the low- and medium-risk subgroups in the IPT only group. CONCLUSIONS In this study, our results suggest that IPT is a safe and effective treatment for extreme hyperbilirubinemia. The indication of ET for patients with hyperbilirubinemia could be stricter. However, it is necessary to have a contingency plan for emergency ET as soon as IPT is commenced especially for infants with risk factors. If IPT can be guaranteed and proved to be therapeutic, ET should be avoided as much as possible.

Objective: To evaluate the long-term efficacy of a second generation biodegradable polymer sirolimus-eluting stent (EXCEL2) in treating patients with de novo coronary artery diseases. Methods: CREDIT Ⅱ trial was a prospective, multicenter, randomized, controlled study, conducted at 15 Chinese cardiac centres from November 2013 to December 2014. In this analysis, eligible patients for coronary stenting (n=419) were randomized to receive either the EXCEL2 stent (n=208) or the EXCEL stent (n=211). The primary endpoint was target lesion failure (TLF) at 3 years after PCI defined as a composite endpoints of cardiac death, target vessel myocardial infarction (TVMI), or clinically indicated target lesion revascularization (CI-TLR). Secondary endpoints included patient-oriented composite endpoint (PoCE) including all-cause death, all MI, or any revascularization at 3 years and independent components, and stent thrombosis according to Academic Research Consortium′s (ARC) definition. Results: Among 419 enrolled patients, 413 (98.6%) patients completed 3-year clinical follow-up. Compared with the EXCEL group, 3-year TLF (5.4%(11/204) vs. 11.5% (24/209), P=0.025) and PoCE (9.8% (20/204) vs. 20.1% (42/209), P=0.003) were significantly lower in the EXCEL2 group. The cumulative event rate of CI-TLR (2.0% (4/204) vs. 5.7% (12/209), P=0.042) and any revascularization (4.9% (10/204) vs. 14.4% (30/209), P=0.001) were statistically lower in the EXCEL2 group than in the EXCEL group. There were no significant difference between two groups in terms of all-cause death and all MI. Rates of stent thrombosis were low without significant difference between the two groups (EXCEL2 vs. EXCEL, 1.0% (2/204) vs. 2.9% (6/209), P=0.285). Conclusion 3-year clinical follow-up results demonstrate that EXCEL2 stents are effective and safe in treating CAD patients with de novo coronary lesions.

Objective: To investigate the effect of excimer laser coronary atherectomy (ELCA) in the interventional treatment of acute coronary syndrome (ACS). Methods: This prospective study enrolled 31 patients with ACS who underwent ELCA treatment in our hospital from November 8, 2016 to December 13, 2017. The efficacy and complications of ELCA were observed, and patients were followed up for postoperative observation of major adverse cardiovascular and cerebrovascular events (including target vessel revascularization, stroke, stent thrombosis, coronary artery bypass grafting, and death). Results: The patients were aged (65.0±10.8) years old and 25 were males (80.6%).There were 5 cases (16.1%) ST-segment elevation myocardial infarction, 3 cases (9.7%) non-ST-segment elevation myocardial infarction, and 23 cases (74.2%) unstable angina in this cohort.There were 9 cases (29.0%) in-stent restenosis, 11 cases (35.5%) saphenous vein graft, 2 cases (6.5%) chronic total occlusive disease, and 4 cases (12.9%) calcification.Two patients with chronic complete occlusive disease and 1 patient with calcified lesion were examined by intravascular ultrasound (IVUS). The other lesions were not examined with IVUS and optical correlation tomography (OCT).The ELCA success rate was 100% (31/31) and the PCI success rate was 100% (31/31).Intraoperative use of 0.9 mm diameter catheters accounted for 38.7% (12/31), 1.7 mm diameter catheters accounted for 32.3% (10/31), and 1.4 mm diameter catheters accounted for 29.0% (9/31).One patient with ST-segment elevation myocardial infarction experienced no reflow of coronary artery during operation. The other 30 patients had no complications such as perforation, small dissection, large dissection, distal occlusion, slow blood flow and collateral occlusion. One cardiac death(3.2%) occurred during the postoperative follow-up of (6.4±1.9) months. Conclusion Our preliminary study results indicate that the use of ELCA in the interventional therapy of ACS is safe and effective.

Objective To investigate the efficacy and safety of domestic exenatide injection versus imported exenatide injection in type 2 diabetic patients with inadequate glycemic control on monotherapy or combination therapy of metformin and insulin secretagogues. Methods A multicenter, randomized, parallel-controlled, and non-inferiority trial was carried out. A total of 240 subjects were randomized at a 1:1 ratio to add domestic exenatide injection (trial group) or imported exenatide injection (control group) on the background therapies. The primary endpoint of efficacy was HbA1C change from baseline to week 16. The secondary endpoints of efficacy were the proportion of HbA1C<7.0%, and the changes in fasting plasma glucose (FPG), 2 h plasma glucose after standard meal (2hPG), 7-point self monitoring of blood glucose (7P-SMBG), and body weight from baseline to week 16. Results Among subjects of per-protocol sets, adjusted mean HbA1C reduction was -1.07% in the trial group versus -1.06% in the control group after 16 weeks of treatment. The lower boundary of the two-sided 95% confidence intervals of the mean HbA1C reduction difference between the trial and control groups was -0.29%, which was more than -0.35%, suggesting that the predefined statistical criterion for non-inferiority was achieved. The proportions of subjects achieving HbA1C<7.0% at the end of the 16-week treatment were 56.19% and 54.08% in the trial and control groups, respectively (P>0.05). The changes in FPG, 2hPG, 7P-SMBG and body weight from baseline to week 16 were comparable between the two groups (all P>0.05). Moreover, the incidences of hypoglycemia and adverse events were similar between the two groups (both P>0.05). Conclusion In type 2 diabetic patients inadequately controlled by monotherapy or combination therapy of metformin and insulin secretagogues, the efficacy of cotreatment with domestic exenatide injection is not inferior to that of imported product ones, with a similar safety profile.

Objective To analyze the clinical, imaging and interventional data of patients with chronic total occlusion (CTO) lesions without myocardial infarction (MI) and to summarize the clinical and imaging characteristics of these patients. Methods The data of 2651 patients with CTO verified by coronary angiography between January 1995 and December 2014 were analyzed retrospectively. Results There were 1466 CTO patients (55. 3%) without MI (the control group) and 1185 CTO patients (44. 7%) with MI ( the MI group). The age, percentage of female patients, unstable angina, hypertention, mean triglyceride levels, left ventricular ejection fraction ( LVEF) were lower in the MI group than in the control group ( all P﹤0. 05). The rates of heart failure and serum creatinine levels were higher in the MI group than the control group (both P﹤0. 05). The rate of multi-vessel disease was higher in the control group than in the MI group (81. 4% vs. 76. 5%, P﹤0. 05). According to the target CTO vessel location, patients in the control group had lower rates of CTO in LAD (36. 2% vs. 40. 7%, P=0. 007) and higher rates of CTO in LCX (17. 0%vs. 12. 7%, P﹤0. 001). Patients in the control group without MI had better collateral circulation than that in the control group (32. 7% vs. 27. 0%, P﹤0. 001). There were no differences in success rate of PCI and complete revascularization between the two groups. Conclusions The present study showed that the CTO patients without MI were associated with better collateral development compared with the CTO patients with MI. Age, gender, unstable angina encouraging ischemic preconditioning and hypertension may be beneficial by facilitating collateral development through endogenous cardioprotective mechanisms.

Objective To compare safety and feasibility using radial versus femoral access during cardiac catheterization of patients who had previously undergone coronary artery bypass graft ( CABG) surgery. Methods We retrospectively evaluated 116 consecutive patients who underwent graft intervention via the transradial (TRA group, n = 46) or transfemoral approach (TFA group, n = 70), and observed the baseline clinical characteristics, angiography characteristics and complications between the 2 groups. Results The baseline clinical characteristics between the 2 groups were similar ( all P > 0. 05) . No significant difference was observed in angiography characteristics and procedural parameters including operation time, radiation exposure and puncture time between the 2 groups (all P > 0. 05). There was no significant difference in major adverse cardiac events during hospitalization. PCI to graft vessels were all successful and procedural success rates were similar between the 2 groups (P = 0. 669). Vascular access site complications were significantly lower ( P = 0. 03) in the TRA group. No access site complication was recorded in the TRA group. 7 cases (10. 0% ) with complications were recorded in the TFA group including 1 case of major bleeding (1. 4% ), 3 cases of minor bleeding (4. 3% ), 2 cases of local hematorna (2. 9% ) and 1 case of A-V fistula formation. Conclusions In contrast to the transfemoral route, the rate of major vascular complications was negligible using the transradial approach.

Objective: To evaluate the long-term efifciency of percutaneous transluminal septal myocardial ablation (PTSMA) for treating the patients with hypertrophic obstructive cardiomyopathy (HOCM).
Methods: A total of 66/94 (70.2%) HOCM patients received PTSMA in Shenyang PLA general hospital from 2001-10 to 2012-10 were retrospectively studied. The left ventricular out lfow gradient (LVOFG) was measured at before and after the operation, ECG and echocardiography were examined at 1 month, 6 months and 1 year after operation, and then examined once per year for (63.8±28.5) months.
Results: There were 26 patients lost contact during follow-up period, 40 returned to routine clinical check-up and 2 patients died thereafter, 1 because of sudden death and 1 because of cerebral bleeding. The pre-operative average LVOTG was (102.7 ± 47.5) mmHg, compared with the values at 6 months post-operation and long term (>6 months) after operation (33.9 ± 30.2) mmHg and (29.7 ± 25.4) mmHg,P<0.001. The pre-operative average inter ventricular septal (IVS) was (20.1 ± 3.6) mm, compared with the values at 6 months post-operation and long term after operation (17.5 ± 2.9) mm and (16.4 ± 3.6) mm, P=0.028 andP<0.001. There were 7 patients with NYHA class at II-III and having occasional chest suppression and short of breath. There were no heart transplantation, frequent premature ventricular contraction, tachycardia and other malignant arrhythmia occurred in 38 survivors.
Conclusion: PTSMA may reduce LVOTG, IVS thickness and improve the clinical symptoms in HOCM patients, the long-term efifcacy is reliable.
