Objective To find the optimal stimulation parameters of electroacupuncture for incision pain and visceral dragging pain after surgery.Method Databases including the China National Knowledge Infrastructure (CNKI), WanFang (WF), VIP and PubMed were retrieved by using computer. The eligible literatures related to the clinical and experimental studies on electroacupuncture for post-operative pain were summarized and the frequencies of the involved electroacupuncture parameters were counted.Result For incision pain, electroacupuncture was used after surgery, with continuous wave, usually a low frequency ranged 2~15 Hz and a current of 2~5 mA; for visceral dragging pain, electroacupuncture was used before surgery, with sparse-intense wave, alternate frequencies majorly at 2/100 Hz and a medium or low current intensity within patient’s endurance. Conclusion In clinical application, the elctroacupuncture parameters should be chosen carefully according to the type of post-operative pain.

BACKGROUND:There is no simple and effective method to relieve delayed muscle soreness.
OBJECTIVE:To conclude the injured mechanism and therapies of delayed muscle soreness by reviewing literature about damage and repair of the skeletal muscle.
METHODWanfang and PubMed databases (from January 1991 to January 2014) were retrieved for articles
related to morphological structure of the skeletal muscle, mechanism of delayed muscle soreness, and treatment and repair of the skeletal muscle using the keywords of“molecular mechanisms;delayed onset muscle soreness;pain;skeletal muscle;injury”in Chinese and English, respectively. Final y, 24 articles were included in result analysis.
RESULTS AND CONCLUSION:Studies have shown that skeletal muscle injury is related to calcium imbalance, energy imbalance and high concentration of active oxygen. Skeletal muscle injury includes metabolic injury, mechanical injury and inflammatory injury. Insulin-like growth factor, peroxisome proliferator-activated receptorγ-coactivator-1αpromoter and tumor necrosis factorαplay important roles in skeletal muscle repair process. Animal experiments have demonstrated that edaravone may reduce secondary damage and inflammatory infiltration by means of directly preventing rapid peroxidation injury of free radicals in the skeletal muscle. Clinical studies have shown that Chinese medicine preparations, massage and acupuncture can delay the occurrence of exercise-induced muscle injury and fatigue, to improve the speed and quality of the recovery of damaged muscles. The treatment of delayed muscle soreness can achieve satisfactory results by combining physiotherapy with traditional Chinese medicine.

BACKGROUND:Ligustrazine has been shown to restore the function of the femoral headviathe revascularization, increased blood flow, theabsorption ofnecroticbone, and bone regeneration. OBJECTIVE:To study the effects of ligustrazine on remodeling of periodontal tissues and the expression of osteoprotegerin in the maintenance phase in rats with orthodontic tooth movement. METHODS:Thirty-two healthy male Wistar rats were included and equaly randomized into four groups. Maxilary left first molar mesialization was performed through traction of 50 g force for 21 days to establish the rat model of tooth movement. 5, 10, 15 mg/L ligustrazine (50 μL) were localy injected into the first molar periosteum in model rats on the day before removing the orthodontic forcing device. Same volume of saline was injected in the control group. The injection was administered every other day. At 1 and 4 weeks after injection, the distance of tooth movement, the recurrence distances and percentage were determined and calculated. The pathological changes in periodontal tissues were observed by immunohistochemistry and hematoxylin-eosin staining. The width ofthe parodontium and number of osteoblasts were observed under an optical microscope. RESULTS AND CONCLUSION:The recurrence distance inthecontrol group was increased compared withtheexperimental group, while the number of osteoblasts and osteoprotegerin immunoreactivity were decreased. Good width of the parodontium and smal recurrence trend were found in 10mg/L ligustrazine group. These findings indicate that ligustrazine promotes the proliferation of osteoblasts and enhances the expression of osteoprotegerin, which is beneficial to the retention of teeth after orthodontic surgery.

BACKGROUND:Mobile-bearing prosthesis has advantages in theoretic design, in vitro kinematics and abrasion, but it remains unclear whether its clinical outcomes are better than fixed-bearing prosthesis at present. OBJECTIVE:To evaluate the medium-term results of total knee arthroplasty using mobile-bearing prosthesis to provide clinical evidence for the choice of prosthesis. METHODS:The patients who suffered from osteoarthritis or rheumatoid arthritis and underwent total knee arthroplasty with PFC Sigma RP in Beijing Tongren Hospital from December 2006 to June 2009 were included in this study. The postoperative Knee Society Score, Knee Society Score Function Score, Patel ar Score and the Pain Score, range of motion, maximun flexion and extension angle were col ected and compared with pre-operation. The complications, such as infection, patel a clicking, polyethylene insert dislocation, and deep vein thrombosis were recorded after replacement. The anterior-posterior, lateral and Merchant position X-ray images were taken to evaluate the tibiofemoral alignment, radiolucent lines, and patel ar dislocation. Then, the results of other medium-term fol ow-up researches were compared with fixed-bearing arthroplasty. RESULTS AND CONCLUSION:Final y, 31 patients (45 knees) were fol owed up. The average age was 64.56±10.33 years, and fol ow-up period was 3.9-7.6 years. The postoperative scores, range of motion, maximun flexion and extension angle were improved obviously, but there were no differences with other medium-term fol ow-up researches. No radiolucent lines, prosthetic loosening or polyethylene insert dislocation was found. Lateral patel ar release was done, but no patel ar dislocation or subluxation appeared in al patients. Two patients (2 knees) accompanied patel a clicking. Results indicated that the medium-term clinical result was satisfactory. No patel ar dislocation or subluxation was found, although only lateral patel ar release was done. This may be the superiority of mobile-bearing arthroplasty.
