Genetic characterization and diversity of porcine circovirus type 2 in non‐vaccinated South African swine herds

The porcine circovirus type 2 (PCV2) is a swine infectious viral pathogen of great significance in global swine herds. It was recently detected at another Province of South Africa sequel to the first detection of North American‐like strain (PCV2a) at Gauteng about two decades ago, but there is a dearth of information about the genomic features and diversity of the viral strains in circulation within the country and the entire sub‐Saharan Africa region. To date, only one complete genome of the virus from South Africa is available on global data base. This current effort is therefore geared towards the full‐genome characterization of the circulating PCV2 strains in the pigs of Eastern Cape Province. With the use of conventional polymerase chain reaction method, fifteen complete PCV2 genomes were successfully amplified, sequenced and assembled from field samples obtained from non‐vaccinated pigs in the region. Neighbor Joining and Maximum Likelihood phylogenetic analyses of the ORF2 gene and full genomes unanimously showed that most of the assembled genomes (11) belong to genotype PCV2b. Furthermore, three of the characterized sequences formed clade with other reference mutant PCV2b and PCV2b subtype 1C (i.e. PCV2d) strains from the USA, China and South Korea. The last sequence, however, clustered with other reference strains belonging to PCV2 intermediate clade 2 (PCV2‐IM2), recently identified in a global PCV2 strains phylogenetic analysis. This study reports the first complete genome sequences of PCV2b, PCV2d and PCV2‐IM2 in pigs from South Africa, and it gives a possible insight into the genetic characteristics and variability of the viral strains presently in circulation within the country. It further emphasizes the need for more stringent measures in curtailing the introduction and spread of transboundary swine pathogens in the country and entire Southern African region.     

临床药师在导管接触性溶栓联合抗凝治疗急性下肢深静脉血栓的用药分析与药学监护中的作用

目的 探讨临床药师在急性下肢深静脉血栓患者个体化治疗中的作用。 方法 对南京鼓楼医院血管外科2018年8月收治的8例急性下肢深静脉血栓患者的治疗过程进行分析，结合临床药学知识制定导管接触性溶栓及抗凝用药方案，对患者实施全程药学监护。 结果 溶栓治疗期间，患者血浆纤维蛋白原水平呈明显下降趋势，血浆D-二聚体水平呈先升高后降低的趋势，血小板未见明显下降趋势；8例患者在溶栓治疗过程中，2例出现轻微牙龈出血后自行止血，1例出现血尿，停止溶栓治疗后改为口服抗凝药，血尿现象消失。患者预后改善明显，血栓完全溶解，静脉恢复畅通，用药安全得到有效保障。 结论 临床药师在导管接触性溶栓联合抗凝治疗急性下肢深静脉血栓患者的个体化用药监护方面发挥了积极作用。     

The relationships among monocyte subsets,miRNAs and inflammatory cytokines in patients with acute myocardial infarction

Background

Acute myocardial infarction (AMI) causes irreversible myocardial damage and release of inflammatory mediators, including cytokines, chemokines and miRNAs. We aimed to investigate changes in the levels of cytokines (IL-6, TNF-α and IL-10), miRNAs profiles (miR-146 and miR-155) and distribution of different monocyte subsets (CD14++CD16-, CD14++CD16+, CD14+CD16++) in the acute and post-healing phases of AMI.

下颌磨牙区即拔即种的临床疗效观察

目的 探究下颌磨牙区即拔即种的临床疗效。方法 选取2017年1月至2019年1月江门市口腔医院收治的60例需进行下颌磨牙区种植的患者随机分为A、B组,A组给予即拔即种,B组给予延期种植,比较两组留存率、浅蝶形骨吸收率、种植12个月后PIS指标及满意度进行评价。结果 随访12个月两组留存率均为100%,浅碟形骨吸收率A组前磨牙为16.67%、磨牙为22.22%,B组前磨牙为10.00%、磨牙为25.00%,差异均无统计学意义(P＞0.05),A组植入30个种植体,60个牙间乳头,其中3度29个、2度24个、1度7个,B组植入30个种植体,60个牙间乳头,其中3度14个、2度24个、1度22个,A组牙间乳头PIS指标优于B组,且A组牙间乳头PIS评分(2.36±0.52)较B组(1.87±0.48)显著提高,差异均具有统计学意义(P＜0.05),A组对治疗效果满意率为93.33%较B组66.67%显著提高,差异具有统计学意义(P＜0.05)。结论 对于下颌磨牙区缺牙患者可采取即拔即种的方法修复,缩短缺牙时间,促进咬合和咀嚼功能恢复,舒适且美观,提高患者的满意度,值得在临床上推广。     

SGLT2 inhibitors for the treatment of diabetes: a patent review (2013-2018)

Introduction: The sodium-glucose co-transporter 2 (SGLT2) is ascribed to target renal tubular glucose re-absorption, and its inhibition has been proved to induce glucosuria which improves the glycemic index. Accordingly, SGLT2 inhibitors have found to be the promising class of antidiabetic agents for the management of type 2 diabetes mellitus. A large number of SGLT2 inhibitors have developed through structural modification and investigated for their ability to selectivity inhibit SGLT2 transporters with better bioavailability.

Areas covered: This review comprises a summary of patent applications (2013–2018) of SGLT2 inhibitors with focus on chemical structural advancement and therapeutic potentials in the management of diabetes and related disorders.

Expert opinion: SGLT2 inhibitors exert multiple metabolic benefits, including reduced glycated hemoglobin (HbA1c), improved glycemic control (fasting and postprandial), reduced body weight, reduced systolic and diastolic blood pressure and improved HDL cholesterol. Due to the virtue of no interference with insulin action and secretion, their efficacy remains the same even in presence of progressive β cell failure in type 2 diabetes. Additionally, few members of this class have been reported to exhibit cardioprotective, renoprotective, and anticancer activity. However, more study on the long-term outcomes in patients taking SGLT2 inhibitors is warranted.
