Preparation of Ni-Co Alloy Foils by Electrodeposition

Electrodeposition of Ni-Co alloy foils on titanium substrate was performed in an acid chloride- sulphate bath. The influences of electrodeposition parameters such as current density, temperature, pH value, cobalt sulphate and saccharin concentration on composition and current efficiency were investigated in detail. The morphology and the microstructure of deposits were analyzed by SEM and XRD, respectively. The results indicated that the optimum parameters were current density 3-4 A/dm2, pH 2-3, temperature 40-50?C, cobalt sulphate 20 g/l and saccharin 2-3 g/l. Chemical analysis of the deposits by EDS revealed anomalous Ni-Co codeposition occured in this system. The SEM showed that hydroxide particles were not present on the surface and that fine-grain, smooth and compact Ni-Co alloy deposits were obtained. The crystallographic structures of Ni-Co alloy foils were the fcc Ni solid solution. The Ni-Co alloy foils with Co content 17.3-37.2 wt% and thickness of 20-45 μm were bright with low residual stress and super toughness.

世界针灸学会联合会:助力中医针灸成为世界针灸

1.History and present。The World Federation of Acupuncture-Moxibustion Societies(WFAS)was established in 1987 as a global society initiated by over 50 acupuncture associations in more than 10 countries,including China,Japan,and France,which was under the guidance of the World Health Organization(WHO).The WFAS is the first international academic organization headquartered in Beijing,China.By September,2023,the WFAS has 261 member societies in over 70 countries and regions,making it the largest international nongovernment organization focused on acupuncture and moxibustion.Since its establishment for over 30 years,the WFAS has actively promoted the international dissemination of acupuncture and moxibustion and has joined into the acupuncture research worldwide.In 1998,the WFAS built official relations with the WHO on traditional Chinese medicine.In 2010,the WFAS was accepted as A-level liaison with the International Organization for Standardization Technical Committee on Traditional Chinese Medicine(ISO/TC 249).In 2019,the WFAS was granted Special Consultative Status with the United Nations Economic and Social Council.

Investigation of international demand for Clinical Practice Guidelines of Acupuncture and moxibustion:A cross-sectional study

Objective:This study aims to get the medical management of acupuncture and moxibustion in the countries and regions where the society members of World Federation of Acupuncture-Moxibustion Societies(WFAS)are located,including the educational background of acupuncture and moxibustion practitioners and the local clinical practice of acupuncture and moxibustion,and the demands of the content and evidence types of Clinical Practice Guidelines(CPGs)of acupuncture and moxibustion in accordance with WFAS standards,so as to provide requirements and reference principles for the development of CPGs of acupuncture and moxibustion in accordance with WFAS standards.Methods:The convenient sampling method was used to collect the questionnaires,and the WFAS secretariat distributed the questionnaires to 294 contacts of society members from 70 countries and regions in the form of Questionnaire Star four times in April 2020,July 2020,March 2021,and April 2021 respectively.They were then distributed to individual members of acupuncture-moxibustion societies by the contacts.The study content involved the basic information of respondents,including their nationality,occupation,educational background of acupuncture and moxibustion,their local clinical practice and medical management of acupuncture and moxibustion,as well as their demand for CPGs of acupuncture and moxibustion,etc.After the questionnaires were collected,the data were analyzed and described by quantitative research method.Results:In all,302 respondents from 37 countries of six continents responded.The 302 respondents were members of the WFAS society members.(1)Basic information of respondents.They all had acupuncture and moxibustion learning experience,among which,76.5%(231/302)had the education background of acupuncture and moxibustion professional college training,and 88.4%(267/302)had experience of acupuncture and moxibustion clinical practice.Acupuncturists or traditional Chinese medicine doctors accounted for 63.9%(193/302),western medicine doctors,nurses,and pharmacists accounted for 18.2%(55/302),and researchers and teachers accounted for 6.3%(19/302).(2)Local clinical practice and medical management of acupuncture and moxibustion.The level of clinical practice of acupuncture and moxibustion varies greatly among the regions where the WFAS society members lived.Among them,more countries in Europe have not included acupuncture and moxibustion in medical insurance than those in other continents(x^(2)=26.049,P<0.01),and more countries have not included acupuncture and moxibustion in public hospital treatment system than those in other continents(x^(2)=113.488,P<0.01).(3)Demand for CPGs of acupuncture and moxibustion.A total of 93.0%(281/302)respondents believed that WFAS CPGs of acupuncture and moxibustion would be helpful for their local practice.The order of their demand and concern for WFAS CPGs was:acupuncture manipulation>latest progress of acupuncture treatment>choice of acupuncture therapies>safety of acupuncture and moxibustion>combination of acupuncture and other programs.A total of 87.4%(264/302)respondents believed that ancient classics could guide clinical practice,and the ancient literature should be used as evidence for the development of guidelines.Conclusion:The respondents are those future practitioners of CPGs of acupuncture and moxibustion conforming to WFAS standards.Commonly they have clinical practice experience and professional education background.They believe that guidelines will be of help to the clinical practice of acupuncture and moxibustion,hope that WFAS CPGs would recommend effective guidelines for acupuncture manipulation and provide the latest progress in acupuncture treatment and so on,and they believe that classical ancient books can guide their clinical practice.It indicates the necessity and feasibility of formulating the WFAS CPGs of acupuncture and moxibustion.In view of the results of this study,it is suggested that the formulation process of WFAS CPGs of acupuncture and moxibustion should take into account the clinical practice level of acupuncture and moxibustion in each region,as well as its legislation and management situation of acupuncture and moxibustion,so as to meet the needs of users as much as possible.

Acu-moxi Around the World Analysis and reflection of characteristics of evidence review by CMS on acupuncture treatment for chronic low back pain

On January 21,2020,the Centers for Medicare&Medicaid Services issued the Decision Memo for Acupuncture for Chronic Low Back Pain,which included acupuncture treatment for chronic low back pain in Medicare.This paper analyzed the characteristics and analytic methods of CMS evidence review.The evidence review of CMS is characterized by focusing on reviewing domestic and international review studies,U.S.evidence-based guidelines,public consultation and patient needs and personnel coverage.The evidence review and analytic method of CMS includes reviewing the literature to evaluate relevant evidence,reviewing the quality and basis of evidence and determining the universality of evidence.The evidence review method of CMS provides enlightenment for the development of acupuncture and moxibustion and the promotion of Traditional Chinese Medicine.China can learn from the experience of CMS and carry out evidence-based medical evaluation of acupuncture and moxibustion around the common diseases in China.We can improve the coverage of medical insurance according to the needs of patients and encourage physicians to give patient education on non-drug therapy.
