BACKGROUND:Patients with rheumatoid arthritis have high cardiovascular disease risks and postsurgical complications such as postoperative infection and wound healing problems in the process of total joint arthroplasty. OBJECTIVE:To retrospectively review the peri-operative risks when undergoing total joint replacement in patients with rheumatoid arthritis, and assess these risks, propose solutions to guide clinical practice for better peri-operative management. METHODS:The studies related with perioperative cardiovascular risk, the risk of infection of total joint replacement were retrieved by the first author from PubMed database, GOOGLE academic database, CNKI database, Wanfang database, VIP database from 2000 to 2015 through computer. The key words in English and Chinese were respectively“Rheumatoid arthritis, Total joint arthroplast, Perioperative management, Infection, Postsurgical complications, Corticosteroid, Disease modifying antirheumatic drugs, Biologics”. Old and repetitive studies were excluded. RESULTS AND CONCLUSION:A total of 97 articles were retrieved. Total y 53 articles which content was inconsistent with the research themes were excluded, and 44 papers were included in the analysis. We should make a comprehensive cardiovascular examination for the patients with rheumatoid arthritis before operation. If the cardiovascular disease of the patient is unstable, this condition should be clarified and treated appropriately before surgery, otherwise, patients need to check heart function, and predict the operation risk;We should reasonably arrange the anti-rheumatism medicines and corticosteroid during perioperative, so as to make a balance between reducing postoperative infection and preventing the condition relapse;Because rheumatoid arthritis often easy to erode the cervical spine, we should conduct routine imaging examination for the patients before total joint replacement. Movement should be gentle when general anesthesia was needed.

BACKGROUND:Repairing tuberculosis bone defect has become a research focus with the development of anti-tuberculosis functional bone tissue engineering scaffold. OBJECTIVE:To evaluate the preparation, drug release performance and osteogenic properties of the anti-tuberculosis functional bone tissue engineering scaffold. METHODS:PubMed, Chinese Journal Ful-text Database, Wanfang databases were searched by computer for articles addressing functional bone tissue engineering scaffold for repair of tuberculosis bone defect. The keywords were“bone tissue engineering scaffold;tuberculosis;bone defect”in English and Chinese. RESULTS AND CONCLUSION:The anti-tuberculosis functional bone tissue engineering scaffold has good drug delivery, biocompatibility, osteogenic properties and anti-tuberculosis properties. As a good choice to avert bone defect relapse, the scaffold enables a long and stable drug release into bone defects to enhance the therapeutic efficacy of anti-tuberculosis drugs topical y. Given the technical deficiencies, we can only combine two drugs with the anti-tuberculosis bone tissue engineering scaffold, although the combined use of three or four anti-tuberculosis drugs is preferred. Additional y, a complete course of anti-tuberculosis treatment often lasts for 6-12 months, which cannot be achieved by the existing anti-tuberculosis bone tissue engineering scaffold. Up to now, the effect of this scaffold has not yet been confirmed in animal models, although how to prepare this scaffold has been reported.

Ghana attaches great importance to the use of traditional medicine. Over the years, Ghana has successively promulgated laws and policies on traditional medicine, which has laid a legal foundation for the research, registration and sales of its herbal products. This article briefly describes the regulation system of herbal and food supplements in Ghana, and sorts out the registration path of Traditional Chinese Medicine (TCM) products as herbal and food supplements. We also briefly analyze the registration information. We believe that TCM products can open the Ghanaian market as food supplements, so as to promote the registration of herbal medicines. TCM enterprise should controlling TCM registration risks, and strengthening the cooperation between the Chinese and Ghana governments. TCM enterprise can leveraging on the advantages of TCM theory and experience, and strengthening cooperation with Ghana's traditional medicine. This article provide advices for the registration and listing of TCM products in Ghana, expanding the market of TCM in Ghana which finally expands to West Africa and the entire African countries.

This paper analyzes the registration regulations and guidelines of Traditional Chinese Medicine (TCM) products in South Africa, summarizes the registration path of TCM products in South Africa, analyzes the Common Technical Document (CTD) data required for registration from the aspects of quality control, safety and effectiveness, and discusses the registration strategy of TCM products in South Africa. This paper suggests that the strategies could include effective management and control of the registration risk of TCM and steady promotion of the products; TCM enterprises can first register low-risk TCM products, then open the South African TCM market, and promote the registration of high-risk TCM products after accumulating some experience; TCM enterprises need to have the awareness of promoting the inheritance, innovation and development of TCM, increase the investment in clinical trials of TCM products, and supplement the clinical effectiveness and safety data of TCM products; Strengthen the quality control of TCM and build an international brand of TCM.

African herbal medicine is widely utilized with a long history. Most African countries have legalized herbal medicine and established a registration and listing mechanism. The present study firstly described the historical exchange and modern trade of TCM between China and Africa, and briefly described the herbal medicine registration management system of African countries from the regulations and guidelines of herbal medicine management and registration management institutions. Then it compared and analyzed the differences of registration systems in African countries from the following aspects: application materials, registration path, quality control and production, effectiveness evidence and food supplements, as well as summarizing the common points of African herbal medicine registration management. The registration strategy of TCM includes assessing the risk of registered investment, building a multilateral and diversified cooperation network between China and Africa, adhering to integrity and innovation, and promoting the international development of TCM, so as to form a standardized registration path of TCM in Africa and expand the TCM market in Africa.
