    Abstract: In the past 37 years, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has undergone various major transmission routes in China, with the world most complex co-circulating HIV-1 subtypes, even the prevalence is still low. In response to the first epidemic outbreak of HIV in injecting drug users and the second one by illegal commercial blood collection, China issued the Anti-Drug Law and launched the Blood Donation Act and nationwide nucleic acid testing, which has avoided 98,232 to 211,200 estimated infections and almost ended the blood product-related infection. China has been providing free antiretroviral therapy (ART) since 2003, which covered 〉 80% of the identified patients and achieved a viral suppression rate of 91%. To bend the curve of increasing the disease burden of HIV and finally end the epidemic, China should consider constraining HIV spread through sexual transmission, narrowing the gaps in identifying HIV cases, and the long-term effectiveness and safety of ART in the future.

    Abstract: It has been shown that glycolytic protein ENO1 (alpha-enolase) contributes to the pathogenesis of pulmonary hypertension through acting smooth muscle cells; however, the roles of ENO1-caused endothelial and mitochondrial dysfunctions in Group 3 pulmonary hypertension remain unexplored. Methods: PCR array and RNA sequencing were used to screen and decipher the differential gene expression by hypoxia-treated human pulmonary artery endothelial cells. Techniques of small-interfering RNA, specific inhibitor and plasmids carrying gene of ENO1, interventions with specific inhibitor and AAV-ENO1 delivery were employed to explore the role of ENO1 in hypoxic pulmonary hypertension in vitro and in vivo, respectively. Assays for cell proliferation, angiogenesis, and adhesion were employed to analyze cell behaviors, while seahorse analysis was used to measure mitochondrial function of human pulmonary artery endothelial cells. Results: PCR array data showed that ENO1 expression increased in human pulmonary artery endothelial cells exposed to hypoxia, as well as in lung tissues from patients with chronic obstructive lung disease-associated pulmonary hypertension and murine model of hypoxic pulmonary hypertension. Inhibition of ENO1 restored the hypoxia-induced endothelial dysfunction, including excessive proliferation, angiogenesis, and adhesion, while overexpression of ENO1 promotes these disorders of human pulmonary artery endothelial cells. RNA-seq showed that ENO1 targets mitochondrion-related genes and PI3K-Akt signaling pathway, which were validated in vitro and in vivo. Mice treated with ENO1 inhibitor exhibited ameliorated pulmonary hypertension and improved right ventricular failure induced by hypoxia. A reversal effect was observed in mice exposed to hypoxia and inhaled adeno-associated virus overexpressing ENO1. Conclusions: These results indicate that hypoxic pulmonary hypertension is associated with an increased level of ENO1 and that targeting ENO1 might reduce experimental hypoxic pulmonary hypertension by improving endothelial and mitochondrial dysfunction via PI3K-Akt-mTOR signaling pathway.

    Abstract: The uptake of proven stroke treatments varies widely. We aimed to determine the association of evidence‐based processes of care for acute ischemic stroke ( AIS ) and clinical outcome of patients who participated in the HEADPOST (Head Positioning in Acute Stroke Trial), a multicenter cluster crossover trial of lying flat versus sitting up, head positioning in acute stroke. Methods and Results Use of 8 AIS processes of care were considered: reperfusion therapy in eligible patients; acute stroke unit care; antihypertensive, antiplatelet, statin, and anticoagulation for atrial fibrillation; dysphagia assessment; and physiotherapist review. Hierarchical, mixed, logistic regression models were performed to determine associations with good outcome (modified Rankin Scale scores 0–2) at 90 days, adjusted for patient and hospital variables. Among 9485 patients with AIS, implementation of all processes of care in eligible patients, or “defect‐free” care, was associated with improved outcome (odds ratio, 1.40; 95% CI, 1.18–1.65) and better survival (odds ratio, 2.23; 95% CI , 1.62–3.09). Defect‐free stroke care was also significantly associated with excellent outcome (modified Rankin Scale score 0–1) (odds ratio, 1.22; 95% CI , 1.04–1.43). No hospital characteristic was independently predictive of outcome. Only 1445 (15%) of eligible patients with AIS received all processes of care, with significant regional variations in overall and individual rates. Conclusions Use of evidence‐based care is associated with improved clinical outcome in AIS . Strategies are required to address regional variation in the use of proven AIS treatments.

    Abstract: The role of dual-antiplatelet therapy with clopidogrel plus aspirin has been demonstrated to substantially decrease the risk of recurrent stroke among patients with minor stroke and transient ischemic attack. We aimed to determine whether the efficacy of clopidogrel-aspirin therapy among patients with minor stroke / transient ischemic attack was influenced by the stratification of CYP2C19 genotype and body mass index (BMI). Methods— CYP2C19 loss-of-function allele (LoFA) carriers were defined as patients with either LoFA of *2 or *3. Low/normal weight and overweight/obesity was defined as BMI 〈 25 and ≥25 kg/m 2 , respectively. Primary outcome was defined as stroke recurrence at 3 months. Results— In a total of 2933 patients, there were 1726 (58.8%) LoFA carriers and 1275 (43.5%) patients with overweight/obesity (BMI ≥25 kg/m 2 ). Stratified analyses by LoFA carrying status and BMI, hazard ratios (hazard ratios 95% CIs) of the clopidogrel-aspirin therapy for stroke recurrence were 0.90 (0.60–1.36), 0.87 (0.56–1.35), 0.65 (0.39–1.09), and 0.40 (0.22–0.71) among subgroups of LoFA carriers with overweight/obesity, LoFA carriers with low/normal weight, LoFA noncarriers with overweight/obesity, and LoFA noncarriers with low/normal weight, respectively, with P =0.049 for interaction. Conclusions— Efficacy of clopidogrel-aspirin therapy in reducing the risk of stroke recurrence is not present in CYP2C19 LoFA noncarriers with overweight/obesity. Our study suggests that BMI significantly influences the correlation between CYP2C19 genotype and efficacy of clopidogrel-aspirin therapy.

    Abstract: The genetic contribution to coronary artery disease (CAD) remains largely unclear. We combined genetic screening with functional characterizations to identify novel loci and candidate genes for CAD. Approach and Results— We performed genome-wide screening followed by multicenter validation in 8 cohorts consisting of 21 828 participants of Han ethnicity and identified 3 novel intragenic SNPs (single nucleotide polymorphisms), rs9486729 ( SCML4 [Scm polycomb group protein-like 4]; odds ratio, 1.25; 95% CI, 1.17–1.34; P =3.51×10 −11 ), rs17165136 ( THSD7A [thrombospondin type 1 domain-containing 7A]; odds ratio 1.28; 95% CI, 1.21–1.35; P 〈 1.00×10 −25 ), and rs852787 ( DAB1 [disabled-1]; odds ratio, 1.29; 95% CI, 1.21–1.38; P =2.02×10 −14 ), associated with CAD with genome-wide significance. The risk allele of rs9486729 and protective allele of rs17165136 were associated with the decreased expression of their host genes, SCML4 and THSD7A , respectively, whereas rs852787 did not have transcriptional effects on any gene. Knockdown of SCML4 activated endothelial cells by increasing the expression of IL-6 , E-selectin , and ICAM and weakened their antiapoptotic activity, whereas the knockdown of THSD7A had little effect on these endothelial cell functions but attenuated monocyte adhesion via decreasing the expression of ICAM , L-selectin , and ITGB2 . We further showed that inhibiting the expression of SCML4 exacerbated endothelial dysfunction and vascular remodeling in a rat model with partial carotid ligation. Conclusions— We identify 3 novel loci associated with CAD and show that 2 genes, SCML4 and THSD7A , make functional contributions to atherosclerosis. How rs852787 and its host gene DAB1 are linked to CAD needs further studies.

    Abstract: Understanding the effect of night shift on hypertension risk in nurses is important to improve the health of nurses and ensure patient safety. This study aimed to evaluate the effect of the frequency and pattern of night shift on hypertension risk and the interaction of them in female nurses. Methods: This cross-sectional study constituted 84 697 female nurses in 13 cities in China. The main contents of the survey included SBP, DBP, the frequency and pattern of night shift, and some other factors that might be associated with hypertension. Logistic regression analyses were used to calculate ORs and 95% CIs to estimate the effect of the frequency and pattern of night shift on hypertension risk and the interaction of them in relation to hypertension risk. Results: Having more than 5 to 10 or more than 10 night shifts per month were significantly more likely to be hypertensive (OR 1.19, 95% CI 1.10–1.28; OR 1.32, 95% CI 1.13–1.54), whereas having less than or equal to 5 night shifts per month was not (OR 1.05, 95% CI 0.95–1.16). The patterns of night shift were all associated with a higher probability of hypertension and participants engaging in rapidly rotating night shift had a lower OR (1.14) than those having slowly rotating night shift (1.23) and permanent night shift (1.46). No significant interaction was observed between the frequency and the pattern of night shift ( P interaction  = 0.281). Conclusion: The frequency and pattern of night shift were associated with hypertension risk in female nurses and no significant interaction was observed between them.

    Abstract: This study evaluated the association among the plasma concentration of ticagrelor, ARC124910XX, aspirin, and salicylic acid with the risk of recent bleeding in patients with the acute coronary syndrome. To this end, we developed an accurate model to predict bleeding. Methods: A total of 84 patients included in this study cohort between May 2021 and November 2021. The risk factors were identified by univariate and multivariate analyses, and statistically significant risk factors identified in the multivariate analysis were included in the nomogram. We used the calibration curve and the receiver operating characteristic curve to verify the accuracy of the prediction model. Results: Multivariable logistic analysis showed that ticagrelor concentration (odds ratio [OR]: 2.47, 95% confidence interval [CI] , 1.51–4.75, P = 0.002), ST-segment elevation acute myocardial infarction (OR: 32.2, 95% CI, 2.37–780, P = 0.016), and lipid-lowering drugs (OR: 11.52, 95% CI, 1.91–110, P = 0.015) were positively correlated with bleeding. However, angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker (OR: 0.04, 95% CI, 0.004–0.213, P 〈 0.001) was negatively correlated with bleeding. The receiver operating characteristic curve analysis showed that ticagrelor concentration and these factors together predict the occurrence of bleeding (area under receiver operating characteristic curve = 0.945, 95% CI, 0.896–0.994) and that ticagrelor concentration 〉 694.90 ng/mL is the threshold of bleeding concentration (area under receiver operating characteristic curve = 0.696, 95% CI, 0.558–0.834). Conclusion: In patients with acute coronary syndrome treated with dual antiplatelet therapy, ticagrelor concentration 〉 694.90 ng/mL was an independent risk factor for bleeding (OR: 2.47, 95% CI, 1.51–4.75, P = 0.002), but ARC124910XX and salicylic acid concentration did not affect bleeding risk ( P 〉 0.05).

    Abstract: There is no standard care for advanced non–small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutation in the third line. Our study aimed to assess the efficacy and safety of gefitinib as a third-line re-challenge treatment for advanced NSCLC patients with EGFR mutation. Materials and Methods: It was a multicenter, open-label, single-arm, phase II study. Stage IIIB/IV NSCLC patients with EGFR exon 19del/L858R mutation, who had benefited from first-line gefitinib treatment followed by second-line chemotherapy, received gefitinib 250 mg/d. The primary objective was disease control rate (DCR) at week 8. Results: Predefined DCR was achieved in 69.8% (95% confidence interval, 49.87-74.91) patients and objective response rate was reported in 4.7% (95% confidence interval, 0.78-13.06) patients. Median progression-free survival (PFS) was 4.4 months and overall survival (OS) was 10.3 months. Baseline T790M-negative patients achieved favorable DCR compared with T790M-positive patients (78.1% vs. 45.5%, P =0.0418), significantly longer median PFS (4.7 vs. 2.0 mo, P =0.0009) and median OS (15.2 vs. 7.7 mo, P =0.0132). We observed a negative correlation of PFS ( r =−0.4396, P =0.0032), and OS ( r =−0.3630, P =0.0167) with mutation abundance of exon 19del/L858R at baseline. Conclusions: Re-challenge with gefitinib is effective and could be a choice for third-line patients after the first-line EGFR-TKI treatment and second-line chemotherapy, especially for the T790M-negative patients.

    Abstract: Epitopes of phospholipase A2 receptor (PLA2R), the target antigen in idiopathic membranous nephropathy (iMN), must be presented by the HLA–encoded MHC class II molecules to stimulate autoantibody production. A genome–wide association study identified risk alleles at HLA and PLA2R loci, with the top variant rs2187668 within HLA-DQA1 showing a risk effect greater than that of the top variant rs4664308 within PLA2R1. How the HLA risk alleles affect epitope presentation by MHC class II molecules in iMN is unknown. Here, we genotyped 261 patients with iMN and 599 healthy controls at the HLA-DRB1, HLA-DQA1, HLA-DQB1, and HLA-DPB1 loci with four-digit resolution and extracted the encoded amino acid sequences from the IMGT/HLA database. We predicted T cell epitopes of PLA2R and constructed MHC-DR molecule-PLA2R peptide-T cell receptor structures using Modeler. We identified DRB1*1501 (odds ratio, 4.65; 95% confidence interval [95% CI], 3.39 to 6.41; P 〈 0.001) and DRB1*0301 (odds ratio, 3.96; 95% CI, 2.61 to 6.05; P 〈 0.001) as independent risk alleles for iMN and associated with circulating anti–PLA2R antibodies. Strong gene-gene interaction was noted between rs4664308(AA) and HLA-DRB1*1501/DRB1*0301. Amino acid positions 13 ( P 〈 0.001) and 71 ( P 〈 0.001) in the MHC-DR β 1 chain independently associated with iMN. Structural models showed that arginine13 and alanine71, encoded by DRB1*1501, and lysine71, encoded by DRB1*0301, facilitate interactions with T cell epitopes of PLA2R. In conclusion, we identified two risk alleles of HLA class II genes and three amino acid residues on positions 13 and 71 of the MHC-DR β 1 chain that may confer susceptibility to iMN by presenting T cell epitopes on PLA2R.
