Objective To evaluate the clinical effectiveness of heat-sensitive moxibustion for knee osteoarthritis ( KOA) by systematic evaluation and Meta analysis methods. Methods Electronic information retrieval combined manual retrieval methods were used for collecting clinical randomized control trial of heat-sensitive moxibustion for KOA. The systematic evaluation was conducted by two individual researcher following the principles of Cochrane Review Handbook 5.1, and RevMan5.0 software was applied for the statistical analysis. Results Fifteen randomized controlled trials (RCT) were enrolled into the analysis, which involved 1228 cases. The results of systematic evaluation showed that the quality of most of the enrolled RCT were not so high. The results of Meta analysis were as follows: ( 1) Between heat-sensitive moxibustion and traditional moxibustion, the weighted mean difference (WMD) and 95%confidence index (CI) were-1.76, [-2.33, -1.18] for visual analog scale ( VAS) scores ( P<0.001) , were -2.36, [-3.42, -1.30] for the scores of guiding principle of clinical research on new drugs ( GPCRND) for KOA ( GPCRND-KOA) ( P<0.001) , and were 13.61, [7.60, -19.61]for Lysholm knee joint function scores (P<0.001), respectively; (2) Between heat-sensitive moxibustion and acupuncture, WMD and 95%CI were 6.19, [ 0.01, 11.37] for Lysholm scores ( P<0.05);(3) Between heat-sensitive moxibustion and warm-needling acupuncture, WMD and 95%CI were -10.14, [-17.47, -2.81] for the Western Ontario and McMaster Universities ( WOMAC) osteoarthritis index scores ( P<0.05). Conclusion It is indicated that heat-sensitive moxibustion shows certain therapeutic effect for knee osteoarthritis, better than traditional moxibustion.

Chinese Journal of Tissue Engineering Research 2008;12(9):1782-1786
BACKGROUND:In some clinical applications or special work conditions,extremely intonse 50 Hz AC intefference exists.As the amplifier's output reaches or is close to saturation,it cannot be suppressed by general anti-interference circuits or software algorithms.Themfore,the hardware circuit must be impreved to suppress this interference,thus obtajning the desired signals.OBJECTIVE:To introduce a biopotential amplifier,which can effectively suppress the impact of 50 Hz AC interference on the weak biomedical signals.DESIGN:Create a circuit model based on the advanced theoretical analysis,then make software emulation and finally design the actual circuit implementation.SETTINGS:the 305 Hospital of Chinese PLA:Institute of Aviation Medicine,Air Force of CIIinese PLA.MATERIALS:The experimentaIinstruments and analytical software were provided by the Institute of Aviation Medicine,Air Force of Chinese PLA:the high-voltage electrical field environment was provided by the 305 Hospital of Chinese PLA.METHODS:The first step was theoretical analysis at the Institute of Aviation Medicine,Air Force of Chinese PLA in 2005,then the 50 Hz anti-reference model was created.After that,the following three anti-reference measures were put forward:①Enhancing the common-mode input impedance of the overall circuit to remove the interference caused by the imbalance electrode impedance;②reducing the equivalent common mode input impedance of the instrument amplifier in the circuit by using a current source controlled by the comlnou mode voltage;③using the driven-right-leg circuit to reduce the common mode voltage.Moreover,emulation analysis was made for the above circuit model by using the circuit emulation software TINA PRO.Through ceaseless improvement of the circuit model,the correct emulation results were obtained.In 2006,the Circuit model helped us realize the electrocardiogram(ECG)amplifier that could suppress the 50 Hz AC intefference effectively in intense interference environments.And that amplifier was put into practical use in the high-voltage electrical field environment produced by the high-voltage electrical field treatment equipment in the 305 Hospital of PLA.The result was satisfying:the 50 Hz AC interference was suppressed effectively and the high-quality ECG signals were obtained.MlAIN OUTCOME MEASURES:Common-Mode Rejection Ratio(CMRR)and the frequency spectrum of signals obtained in intense intefference environment,which are used to assess the ability against the 50 Hz AC interference.RESULTS:A 100 ù resistor or a 200 kù resistor were connected in series in the input loop so as to produce the imbalance electrode impedance status.When the imbalalice electrode impedance was 100 ù,the amplifier output was 1.69 Mv,and CMRR was 125.8 Db.When the imbalance electrode impedance was 200 k ù,the amplifier output was 1.78 Mv,and CMRR was 125.3 Db.Two voltage sources(20 Hz,amplitude of peak to peak value 50 ì V,opposite phases)were used to produce differential mode signals.The amplification gain was 1000 times.In the input loop of the circtilt mentioned above,a 200 kù resistor was connected in series to create the inabalance electrode impedance status.The amplifter output the peak-to-peak value 50 Mv.The fast Fourier transform(FFT)frequency spectrum of the output wave contained no 50 Hz spectrum line.CONCLUSION:Through the emulation experiment and the real application.we can all find that the amplifier has good signal amplification performance and anti-interference capabillty in intensive 50 Hz AC interference environments and severe imbalance electrode impedance Status.

Collaterals is a term in Traditional Chinese Medicine (TCM) in human body.It is the branch of the Channels and Collaterals that consists of DaLuo,XiLuo,ChanLuo,SunLuo and FuLuo,etc.Its function are transporting qi and blood,connecting zang- fu organs and limbs, as well as the upper and the lower,the interior and the exterior, and regulating all parts of the body.Collaterals disease is the disorder of the function of transporting qi,blood and body fluid,and the pathologic metabolite interference in Collaterals due to various agents. There are many therapy such as communicating Collaterals with Pungent Flavour and Moistening,Pungent Flavour and Worm, Pungent Flavour,Clearing away Heat and promoting the dispersing function, Aromatic,Clearing away Heat,Clearing away thrombosis,Clearing away sputum,insect and ants therapy,promoting qi, moistening and promoting,Clearing and moistening,worming and moisting and Softening liver, etc.

Chinese Traditional and Herbal Drugs 1994;0(01):-
Triptophenolide (TN) is a colorless crystalline plate isolated from ethyl acetate extracts of Tripterygium wilfordii. It can obviously inhibit the edema caused by xylol and mixture croton oil; and decrease the concentration of Vitamin C in the adrenal gland of mice.TN can remarkably inhibit the delayed type hypersensitivity (DTH) reaction induced by DNCB and BSA; and diminished the peripheral blood ANAE+lymphocytes in rats and micc.Moreover, TN can dramatically increase the amount of total serum complement and significautly decrcase the serum antibody products (1gG ) of rats and mice. The phagocytosis of perioneal exudate macrophages in mice present double effects in vitro. TN can promote the phagocytosis of macrophages at the small dosage, but at larger dosage, it showed inhibition.The results mentioned above showed that triptophenolide may be one of the main effective component of T.wilfordii for treating auto-immune diseases.
