中药材产业扶贫的空间格局及其主要影响因素探讨

通过对"全国中药资源普查及种质共享数据专题服务——中药材产业扶贫"数据资料及"康美中药网——中药全产业链服务平台"各贫困地区中药材资源信息的整理分析,构建中国贫困地区的中药材种植面积、产值等数据库,利用ArcGIS软件绘制贫困地区中药材种植情况空间分布图,从中发掘和总结当前我国中药材产业扶贫的空间格局特征和发展规律。在此基础上,通过参考"中国减贫数据库"及"国务院扶贫开发领导小组办公室"的相关报告,综合分析影响中药材产业扶贫成效的主要因素,并提出相应的建议,以期对贫困地区开展中药材产业扶贫工作提供参考。     

动物药材生产及产地加工技术标准体系建设

药用动物资源是中药资源的重要组成部分,是中医药发展的重要战略储备资源,在野生药用动物资源日渐匮乏的今天,大力开展药用动物人工养殖才能确保我国中医药产业的可持续发展。然而《中国药典》2015年版一部收载的106种药用动物中仅有22种(除家畜家禽外)有现行选育、养殖相关标准,共211项,其中除国家标准7项、行业标准(农业、水产)11项外均为地方标准,远远落后于同类型农业标准化程度,无法实现动物药材规范化生产。亟需对常见动物药材蟾酥、水蛭、全蝎等建立包括基础标准、产品标准、工艺过程标准、安全标准、环境保护标准、管理标准、工作标准在内的动物药材生产及产地加工技术标准体系,补充产业空白,从源头把控动物药材、动物类中药饮片及含有动物性成分中药产品质量。     

Digital tools and 3D printing technologies integrated into the workflow of restorative treatment: A clinical report

The development of technologies including intraoral scanners, dental software for digital restoration design, and additive manufacturing has improved the digital workflow of restorative treatment. The present article describes a digital workflow with intraoral scanning, computer-aided design (CAD) software, and subtractive and additive manufacturing procedures for a patient receiving lithium disilicate laminate veneers.     

Outcome of sentinel lymph node biopsy in early-stage squamous cell carcinoma of the oral cavity with methylene blue dye alone: a prospective validation study

Our aim was to evaluate the feasibility and role of sentinel lymph node (SLN) biopsy using methylene blue dye alone in identifying occult lymph node metastases in early oral cancer (cT1, T2, and cN0). The study was done from 2013–15 in 94 patients in a large cancer centre. The blue nodes were dissected and sent for frozen section, routine histopathological examination, and immunohistochemical testing for cytokeratin, and was followed by elective neck dissection in all patients. The identification rate was 93.61%. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for frozen section and haematoxylin and eosin (H&E) staining were 84.6%, 100%, 100%, 93.9% and 95.5%, respectively. Occult lymph node metastasis was seen in 27.6% cases. Biopsy of SLN with blue dye alone might be used successfully with good sensitivity and negative predictive value in countries with limited resources in the developing world. Immunohistochemistry contributes to it by increasing the sensitivity and NPV, and thereby improves the diagnostic value.     

Fracture resistance and 2-body wear of 3-dimensional–printed occlusal devices

Statement of problem

Polymeric material for 3-dimensional printing can be used to fabricate occlusal devices. However, information about fracture resistance and wear is scarce.

Bone mineral density changes after parathyroidectomy are dependent on biochemical profile

Background

Bone mineral density (BMD) has been found to improve after parathyroidectomy (PTX) in patients with primary hyperparathyroidism. There are few data on the effect of PTX on BMD in normocalcemic and normohormonal primary hyperparathyroidism.

Stakeholders' viewpoints on work-integrated learning practices in radiography training in South Africa: Towards improvement of practice

Purpose

The aim of this investigation was to suggest practices to improve the delivery of work-integrated learning (WIL) in radiography training in South Africa (SA).

Implementing a holistic approach to a radiographer-led Hysterosalpingogram (HSG) service: A review of impact and patient perception

IntroductionRadiographer role development has touched boundaries across the multidisciplinary team and more recently branched into the field of gynaecology. Radiographers are now able to perform tasks that were traditionally performed by radiologists and gynaecologists to implement a radiographer-led Hysterosalpingogram (HSG) service. The aims of the study were to (i) implement a radiographer-led HSG service with a view to decreasing waiting times. (ii) To determine ladies perceptions and satisfaction levels.MethodLocal clinical guidelines were developed with the radiologist/gynaecologist and trainee HSG radiographers. A robust system of work was initiated which required maintaining comprehensive log books to record examinations performed and reports written. These were audited and compared with those of the radiologist. Audit cycles were monitored through Q Pulse to ensure good practise was maintained. Patient satisfaction surveys were developed and distributed to 100 consecutive ladies attending for HSG over a 6 month period from January–July 2017.ResultsThe radiographer-led service has increased the number of appointment slots offered for HSG's throughout the year as the service now runs every week. HSG's were performed by 5 staff members but now only require 3 staff. A 75% response rate was achieved from the questionnaire survey and shows high patient satisfaction levels. Ladies reported being better informed about their examination resulting in decreased anxiety, concerns and discomfort.ConclusionThe implementation of this service has successfully reduced waiting lists for HSG examinations from 14 to 0 weeks. The Trust has saved £15,000 on staff salaries per annum since the service started.
