With the emergence of the modified forms of acupuncture-moxibustion such as dry needle,the discipline acupuncture-moxibustion faces significant opportunities and challenges.The concept and treatment of acupuncture-moxibustion need to combine with modern medicine to consolidate the effectiveness and apply the research results to guide clinical treatment.By reviewing the brief history of acupuncture-moxibustion in the Western countries and summarizing the definitions,this article was to propose the trend and development strategies of this discipline in the future.

BACKGROUND:A number of in vitro experiments have confirmed that the tricalcium silicate not only can be closely integrated with the dentin through self-curing process, but also can induce dentin remineralization in the physiological environment, thereby effectively blocking the dentinal tubules.
OBJECTIVE:To further verify the effects of tricalcium silicate solution on the occlusion of dentinal tubules.
METHODS:Thirty-six dentinal discs were made of free first premolars from orthodontic patients, and divided into three pretreatment groups randomly. The teeth were soaked in pretreatment solution for 2 minutes, namely 0.29 mol/L ethylene diamine tetraacetie acid, 6%citric acid, and rinsed ultrasonical y with deionized water 20 minutes, respectively. Every above-mentioned group was randomly assigned into experimental group (tricalcium silicate), control group (sodium fluoride) and blank group, and corresponding materials in each group were used to coat the outer dentinal tubules (2 minutes/time). Then, the dentinal discs were saved in artificial saliva in a 37 observed using scanning electron microscope. Diameter and area of open dentinal tubules were calculated.
RESULTS AND CONCLUSION:After pretreatment, the dentinal tubules were at open state;except for the blank control group to maintain the original state, acid etching and ethylene diamine tetraacetie acid pretreatment solutions had a stronger capacity of demineralization, which led to the dentinal tubules open. After the dentinal tubules were treated with sodium fluoride and tricalcium silicate, there were varying degrees of sediments, and open dentinal tubule area and average diameter in the sodium fluoride and tricalcium silicate groups were lower than those in the control group (P<0.05). The dentinal tubule treated with tricalcium silicate was almost entirely closed homogeneously, and occasional y, a single open dentinal tubule was seen. Open dentinal tubule area and average diameter in the tricalcium silicate group were significantly lower than those in the sodium fluoride group (P<0.05). The findings verify that dentin occlusion using tricalcium silicate is superior to that using sodium fluoride;and dentin tubule pretreatment with acid etching or ethylene diamine tetraacetie acid is beneficial to desensitization effects.

Objective To evaluate the accuracy and sensitivity of three techniques in the diagnosis of renal diseases following multiple myeloma. Methods 41 serum samples from the kidney-damaged patients with multiple myeloma and 36 from the control group with general renal diseases were detected by quantitative analysis of immunoglobulins, serum protein electrophoresis and serum Immunofixation Electrophoresis. The accuracy and sensitivity of the three techniques were analysed by Two-way ANOVA and Multiple Comparisons of the check-out rate of monoclonal immunoglobulin. Results No monoclonal components were checked out by quantitative analysis of immunoglobulins. The checkout rate of IgG and IgM myelomas were 100% by serum protein electrophoresis, which had application limit on other types of myelomas. Whereas all secretarial myelomas could be diagnosed and typied by Immunofixation Electrophoresis, the sensitivity and accuracy was 100%, there was no false positive in the control group. Comparing with quantitative analysis of immunoglobulins and serum protein electrophoresis, serum Immunofixation electrophoresis had higher sensitivity and accuracy in diagnosis of renal diseases following multiple myeloma ( P

Objective To approach the dynamic change in the membrane protein on platelet microparticles of patient with anti-platelet therapy, and look for a new test which are helpful to supervise the anti-platelet therapy. Method We collected blood samples from the patient with myocardial infarction ( n =9) treated with ticlopidine (250 mg?2 in the first and second day, 250 mg/day from the third to sixth day)in different time (before treatment, and 4 d, 5 d, 6 d, 9 d, 10 d after treatment), and examine the percent of PAC-1 + PMP or CD62p + PMP in the samples by activating platelet with 20 ?mol ADP. Result By activating platelet with 20 ?mol ADP, the percent of CD62p + PMP at different time (before treatment, and 4 d, 5 d, 6 d, 9 d, 10 d after treatment) were 84.3%?3.6%, 81.4%?3.4%, 70.3%?2.7%, 70.6%?3.2%, 83.5%?2.8%, 85.4%?2.1%,as of PAC-1 + PMP were 85.3%?3.5%, 82.5%?2.2%, 72.3%?3.5%, 72.4%?3.3%, 85.4?3.4%, 86.0%?3.8%.
