Efficacy of an eConsult service to cure hepatitis C in primary care

In 2016, an eConsult service was developed within a safety net health system to expand access to hepatitis C (HCV) treatment in the primary care setting. The eConsult system provides individualized treatment recommendations from specially trained primary care pharmacists and primary care physicians to primary care providers with less experience in the rapidly changing treatment of HCV. Since its launch, this service has had a large impact in expanding care to a largely homeless and low-income urban population within our health system. We now aim to evaluate its efficacy in curing HCV. In this retrospective cohort study, we describe rates of sustained virologic response 12 weeks after treatment completion (SVR12) for those who received primary care-based HCV treatment through the eConsult system with those who were treated in primary care independent of an eConsult from 2017 to 2019. We found there was no significant difference in the proportion of patients who achieved SVR12 between the two groups. Overall, >90% of patients who received treatment achieved SVR12. Approximately 40% of patients treated for HCV received an eConsult, suggesting utility of the eConsult in expanding access and coordinating treatment for patients within our network.     

飞秒激光辅助超声乳化联合Ahmed青光眼引流阀植入术治疗合并难治性青光眼的白内障

目的：评估飞秒激光辅助超声乳化联合Ahmed青光眼引流阀植入术治疗合并难治性青光眼的白内障的有效性和安全性。

方法：回顾性病例对照研究。2019-10/2021-10入院合并难治性青光眼的白内障患者53例53眼，依据自愿选择分为飞秒激光辅助白内障超声乳化(FLACS)组26例26眼和常规白内障超声乳化(CPCS)组27例27眼。两组分别行FLACS和CPCS联合Ahmed青光眼引流阀植入术。比较两组患者术中超声乳化能量释放量(CDE)、有效超声时间(EPT)的差异和术前与术后抗青光眼药物数量的变化，以及术后观察不同时期(1d，1wk，1、3mo)在提高最佳矫正视力(BCVA)，降低眼压、角膜内皮细胞损伤程度和手术并发症及成功率状况。

结果：FLACS组术中CDE和EPT明显低于CPCS组(t=8.50、5.16； P<0.01、=0.001)。两组术后抗青光眼药物较术前均明显减少(t=9.12、7.76； P=0.011、0.016)，但两组间无差异(t=1.79，P=0.082)。两组术后BCVA均较术前改善，眼压均较术前降低(P<0.05)。FLACS组在术后早期(1d，1wk)BCVA的改善较CPCS组更显著(t=9.74、8.49； P=0.008、0.012)，但在术后1、3mo的BCVA改善程度并无不同(t=0.62、0.44； P=1.415、2.021)。CPCS组在术后随访不同时期的角膜内皮细胞损伤较FLACS组更明显(P<0.05)。术后随访的不同时期FLACS组和CPCS组在控制眼压方面无差异(F_组间=0.64，P_组间=0.421)。FLACS组的手术并发症发生率27%(7/26)较CPCS组89%(24/27)低(χ²=20.95，P<0.01)，其中角膜水肿(8% vs 41%)、前囊撕裂(0 vs 11%)在FLACS组中明显低于CPCS组，后囊破裂(0 vs 7%)、玻璃体脱出(0 vs 4%)及人工晶状体偏位(0 vs 7%)也均发生在CPCS组。但两组的治疗总成功率相近(P=28.718)。

结论：飞秒激光辅助超声乳化联合Ahmed青光眼引流阀植入术可充分发挥联合手术的精准微创可控优势，帮助合并难治性青光眼的白内障患者有效降低眼压及更早获得视力恢复。     

Cyanidin-3-glucoside protects against high glucose-induced injury in human nucleus pulposus cells by regulating the Nrf2/HO-1 signaling

Cyanidin-3-glucoside (C3G) is a well-known natural anthocyanin with antioxidant and anti-inflammatory properties. In this study, we explored the role and action mechanism of C3G in high glucose (HG)-induced damage of human nucleus pulposus cells (HNPCs). Cell viability was assessed by CCK-8 assay. TUNEL assay was performed for detecting apoptotic rate. Western blot was performed to determine the expression levels of cl-caspase-3, caspase-3, Bax, Bim, collagen II, aggrecan, MMP-3, MMP-13, and ADAMTS5. Reactive oxygen species (ROS) generation was analyzed using DCFH-DA staining. The Nrf2 was knocked down or overexpressed in HNPCs through transfection with si-Nrf2 or pcDNA3.0-Nrf2. C3G treatment (12.5, 25, and 50 μM) improved cell viability of HNPCs under HG condition. HG-induced cell apoptosis of HNPCs was attenuated by C3G with decreased apoptotic rate and relative levels of cl-caspase-3/caspase-3, Bax, and Bim. C3G treatment caused significant increase in expression levels of collagen II and aggrecan and decrease in the relative levels of MMP-3, MMP-13, and ADAMTS5. After treatment with C3G, ROS generation in HNPCs was markedly reduced. Treatment with N-acetylcysteine (NAC) reversed HG-induced cell apoptosis and extracellular matrix (ECM) degradation. C3G treatment induced the expression of Nrf2 and HO-1 in HG-induced HNPCs. Moreover, knockdown of Nrf2 reversed the inhibitory effect of C3G on ROS production. Summarily, C3G exerted a protective effect on ROS-mediated cellular damage in HNPCs under HG condition, which was attributed to the induction of the Nrf2/HO-1 signaling pathway.     

江西省锐尖山香圆亲缘关系与群体结构的ISSR分析

目的:利用简单序列重复区间扩增多态性(ISSR)分子标记技术对江西省锐尖山香圆进行亲缘关系和遗传结构分析,为该药材资源的保护和利用提供理论依据。方法:采集江西省4个县6个采样地的22份锐尖山香圆叶片样本,利用试剂盒法提取基因组DNA。利用64条通用ISSR分子标记引物进行聚合酶链式反应(PCR)扩增,运用聚丙烯酰胺凝胶电泳(PAGE)方法检测条带。选择NTsys 2. 10e软件,采用非加权配对算术平均法(UPGMA)计算遗传相似系数并聚类分析。利用Structure 2. 1软件分析群体遗传结构。结果:有48条ISSR引物扩增后获得了产物,多态性条带百分率处于45. 45%～100%。UPGMA聚类分析表明4个县的锐尖山香圆资源不能按照行政区域划分分别聚为一类,群体遗传结构分析表明22份锐尖山香圆群体可以划分为3个类群。结论:江西省锐尖山香圆群体间存在着基因交流,会影响该药材不同地理来源种质资源的遗传结构组成。     

miR-147对胶质瘤U87细胞增殖、凋亡和侵袭的影响

目的:比较胶质瘤患者胶质瘤组织和瘤旁组织中miR-147表达水平的差异性，进一步分析miR-147与胶质瘤细胞生物学活性的相关性。方法:通过实时荧光定量PCR检测65例胶质瘤患者瘤组织和瘤旁组织中miR-147的表达水平；采用Lipofectamine 2000转染法转染胶质瘤细胞，分为miR-147 mimics组和NC组，检测两组转染效率；进一步通过CCK-8实验、流式细胞实验和Transwell实验比较两组细胞生物活性。结果:胶质瘤组织中miR-147表达水平显著低于瘤旁组织；与NC组比较，miR-147 mimics组细胞不论是增殖能力还是侵袭能力都明显降低，但是，miR-147 mimics组的细胞凋亡率升高。结论:胶质瘤组织中存在miR-147低表达的现象。miR-147在胶质瘤细胞中表达升高能够抑制细胞的增殖能力、降低其侵袭能力，并促使更多的细胞发生晚期凋亡。miR-147可能在胶质瘤中扮演着抑癌基因的重要角色。     

A phase I study investigation of metabolism,and disposition of [ 14 C]-anlotinib after an oral administration in patients with advanced refractory solid tumors

Anlotinib is a novel oral multi-targeted receptor tyrosine kinase inhibitor, which selectively inhibits VEGFR2/3, FGFR1-4, PDGFR α/β, c-kit, and Ret. It shows antitumor effect in patients with advanced refractory solid tumors. The detailed absorption, metabolism, and excretion pathways of anlotinib have not yet been fully investigated. Six male patients were enrolled and divided into two groups. Group A (containing two patients) received 14.15 mg/80 µCi/subject [14C]-anlotinib hydrochloride. Group B (containing four patients) received 14.15 mg/120 µCi/subject [14C]-anlotinib hydrochloride. The blood, urine, and feces of all the six patients after orally administration of [14C]-anlotinib were collected. The absorption, metabolism, and excretion of [14C]-anlotinib were investigated, and the efficacy and safety of anlotinib were evaluated. In plasma, the average time to peak concentration (Tmax) of total radioactivity was 4.42 h and the average peak concentration (Cmax) of total radioactivity was 18.80 ng Eq./g. The average values of AUC0-last, AUC0-∞, and MRT0-t were 4071 h.ng Eq./g, 13,555 h.ng Eq./g, and 125 h, respectively. The average recovery of total radioactivity (TRA) in urine and feces was 62.03%, accounting for 48.52% and 13.51% in feces and urine of the total dosage, respectively. The parent drug, a carboxylic metabolite (M30), and mono-oxidation products (M46/M66) were major drug-related components in human plasma. Oxidative metabolism played the major role in drug clearance in human. The major metabolic pathways include oxidative deamination to M2, mono-oxidation to M1, and the formation of M30. Adverse events occurred in five patients and severe adverse events (SAE) occurred in one. Tumor response were evaluated as stable disease (SD) in three, partial response (PR) in one, and progressive disease (PD) in one of the patients, respectively. Anlotinib had a good pharmacokinetic profile with rapid absorption, long half-life, and extensive hepatic metabolism. The adverse events and efficacy were as expected.
