Diseases of the joints of the ext remi ti es, especially sputum, wr ist spr ains, and periarthritis of the shoulders, and even lumbar disc herniation, use X-shaped balance acupuncture therapy to relieve pain and improve motor function. The method of obtaining acupoints is simple and easy to operate. Many of clinical comparison shows that this therapy is simple to conventional acupuncture and moxibustion in the treatment of local pain and joint diseases. This review concluded the advantaged about the X-shaped balance acupuncture therapy and it worth to clinical promotion.展开更多

This study aimed to assess the efficacy and safety of the traditional Chinese medicine, Niaoduqing particles, for delaying renal dysfunction in patients with stage 3b-4 CKD.Methods： The present study was a prospective, randomized, double-blind, placebo-controlled, naulticentcr clinical trial. Frorn May 2013 to December 2013,300 CKD patients with an estimated glomerular filtration rate （eGFR） between 20 and 45 ml ＂rain ~＂ 1.73 m 2, aged 18-70 years were recruited from 22 hospitals in 11 Chinese provinces. Patients were randomized in a 1：1 ratio to either a test group, which was administered Niaoduqing particles 5 g thrice daily and 10 g before bedtime for 24 weeks, or a control group, which was administered a placebo using the same methods. The primary endpoints were changes in baseline serum creatinine （Scr） and eGFR after completion of treatment. The primary endpoints were analyzed using Student＇s t-test or Wilcoxon＇s rank-sum test. The present study reported results based on an intention-to-treat （ITT） analysis. Results： A total of 292 participants underwent the ITT analysis. At 24 weeks, the median （interquartile range） change in Scr was 1.1 （-13.0-24.1） and 11.7 （-2.6-42.9） p, mol/L for the test and control groups, respectively （Z = 2.642, P = 0.008）, and the median change in eGFR was -0.2 （-4.3-2.7） and -2.2 （-5.7-0.8） ml.min-1·1.73 m-2, respectively （Z = -2.408, P = 0.016）. There were no significant differences in adverse events between the groups. Conclusions： Niaoduqing particles safely and effectively delayed CKD progression in patients with stage 3b-4 CKD. This traditional Chinese medicine may be a promising alternative medication for patients with moderate-to-severe renal dysfunction.展开更多

The RIF pathology has complicated extracellular and intercellular mechanisms, involving many cells and cytokines, resulting in an incomplete mechanistic understanding of the disease. Finding effective herbs or herbal extracts for prevention and treatment of RIF is crucial because current medical approaches do not reliably slow or reverse RIF. In recent years, many experts have worked to identify herbs or herbal extracts to combat RIF both in vivo and in vitro, with some success. This review attempts to summarize the possible interventional mechanisms of herbs or herbal extracts involved in protecting and reversing RIF. The authors found some herbs and their extracts that may ameliorate renal impairments through anti-inflammation, anti-fibrogenesis and stabilization of extra cellular matrix. Among them, tetramethylpyrazine/ligustrazine, curcumin and polyglucoside of Tripterygium have experimentally shown good potential for improving RIF. However, conclusive evidence is still needed, especially in randomized controlled clinical trials. We expect that herbs or herbal extracts will play an important role in RIF treatment and reversal in the future.展开更多
