OBJECTIVE:To review the recent advances in analgesics study and summarize the drugs for central sensitization and analgesia model by relating to the latest means and methods of research.DATA SOURCES:The literature on analgesics was retrieved in NCBI database for the related papers published between January 1996 and December 2001, with the key words of "analgesia", "analgesic", and "pain"and language restricted to English. At the same time, papers published in the past two years were retrieved in http:∥www.wanfangdata.com.cn, with the key words of "analgesia", "analgesic" and "ganglioplegic" in Chinese and the language restricted to Chinese.STUDY SELECTION:Totally more than 50 000 research references repeated contents.DATA EXTRACTION: Altogether 100 basic research articles were collected. We selected 15 articles relevant to the research development in analgesic drugs, and excluded 82 review papers with repeated content.expressed by proto-oncogene c-Fos located in the nucleus is a kind of DNA conjugated protein. It can regulate the expression of some pain-related genes. Some studies found that substance P synthesis is likely to play a research: Developing the central sensitization drugs is the orientation of sal root ganglion neurons and model of swallowing response were established.CONCLUSION:By investigating the effects of various new research methods and models on pain, we intended to look for more new drugs, to further study neurotransmitters and the clone of transmitter receptor at the cellular and molecular level so as to find the new effect target of the drugs, and to have a better understanding of the integrity of chronic pain in humans and achieve more breakthroughs in the development of neuroscience research.

The mechanisms of food allergy include IgE-mediated and non IgE-mediated immune responses.Food intolerance is the reaction of defected digestive function caused by many factors in which the immune system is not involved.Clinically,the cases of food intolerance are increasing and the symptoms of the disease are usually complicated.Clinicians are facing the problem of differential diagnosis of food allergy and food intolerance,this article reviews the mechanisms of these two diseases to provide the reference for differential diagnosis.

0.05).Conclusions The serum MMP-9 can be tested as an objective index in appraisal the severity of the left to right shunt.The increased level of MMP-9 may be one of important mechanism for developing heart failure process in children with left to right shunt CHD.Monitor the level of MMP-9 will help us find adverse myocardial remodeling earlier and begin treatment immediately to prevent heart failure developing.

Objective To compare the clinical outcomes of arthroscopy versus mini-incision surgery for the treatment of avulsion fracture of the tibial attachment of the posterior cruciate ligament (PCL).Methods From March 2001 to September 2009,84 patients with acute displaced avulsion fracture of the tibial PCL attachment were treated operatively in our department.Thirty-five patients were treated with arthroscopic reduction and suture fixation (Group 1); 49 patients were treated with open reduction through a mini-incision and internal fixation with cannulated screw(s) and washer(s) (Group 2).There were 27 males and 8 females in group 1,with a mean age of 29.6 ± 5.6 years old,and 40 males and 9 females in group 2,with a mean age of 32.2 ± 7.6 years old.Based on the Meyers & Mckeever classification,there were 24 type Ⅱ fractures and 11 type Ⅲ fractures in group 1,and 31 type Ⅱ fractures and 18 type Ⅲ fractures in group 2.The 2 groups were compared in terms of range of motion,posterior drawer test (PDT),Lysholm score,International Knee Documentation Committee (IKDC) grading,and clinical results.Results All the patients obtained an average follow-up of 21.5 months (range,13 to 34 months).Primary union was achieved in all the fractures 3 months postoperatively.There were no significant differences between group 1 and group 2 regarding the PDT negative rate [82.9％ (29/35) versus 91.8％ (45/49)],the Lysholm score (95.1 ± 5.6 versus 96.1 ±4.7),therate ofIKDC grade A [88.6％ (31/35) versus91.8％ (45/49)],or the rate of normal range of motion [94.3％ (33/35) versus 93.9％ (46/49)] (P ＞ 0.05).On average,group 1 used significantly longer operative time (92.4 ± 15.9 minutes) than group 2 (53.8 ± 14.3 minutes).Conclusions Both arthroscopy and mini-incision surgery can achieve satisfactory clinical outcomes in the treatment of PCL tibial avulsion fracture.Although the 2 methods make no significant differences in stability of the knee joint and clinical scores,mini-incision surgery can result in much shorter operative time and thus permit an early postoperative rehabilitation.

After 160 cases of chronic type Ⅲ prostatitis were divided into the treatment group (n= 80) and control group (n = 80), in the treatment group, first Zhibian (BL 54) was punctured toward Shuidao (ST 28) and then Qihai (CV 6), Guanyuan (CV 4), Shuidao (ST 28)Baihui (GV 20), Fengchi (GB 20), Sishencong (Ex-HN 1), Sanyinjiao (SP 6) and Taichong (LR 3) were punctured, and at the same time, digital computerized microwave apparatus was inserted into the anus for microwave treatment. Afterward, moritatherapy was applied for psychological consultation for the patients. In the control group, compound sinomin and Phenoxybenzamine Hydrochloride Tablets were used orally. The results showed that the therapeutic effects were respectively 92.5% and 68.8% in two groups, with statistic significance (P ＜ 0.01).

Objective To describe the arthroscopic reductions and fixation of tibial intercondylar eminence fracture with cannulated screws. Methods During February 2003 to September 2005, 40 patients were treated arthroscopically for fracture of the tibial intercondylar eminence. The average age was 29.5 years (11-58 years), with a mean follow-up time of 20.1 months(6-37 months). Among the 40 patients, there were 4 type Ⅱ fractures (10%), 24 type Ⅲ fractures (60%) and 12 type Ⅳ fractures (30%). The fragments were reduced and fixed with cannulated screws. All-arthroscopic technique was adopted in all cases. The hematoma and the fragment were debrided, and the bony fragment was reduced and temporarily fixed with 2-3 guide wires through the portal superomedial to the patella. Intra-operative X-ray was taken to prove the reduction. One or two cannulated screws were used to fix the fragment as the definite fixation. Results The fracture healed completely in all but 1 patient. Lachman test were negative in all patients postoperatively. The average postoperative KT-1000 manual maximum displacement(MMD) was 0.625 mm(?蛳1-2 mm) and average Lysholm score was 98.3 points(87-100 points). The range of motion was normal in 34 patients. Flexion deficit was found in 5 cases, but within 10?. Knee joint stiffness was found in 1 case with range of extension and flexion 0?-30?-45?. A secondary operation with arthroscopic release was performed. The range of extension and flexion was improved to 0?-10?-80? postoperatively. Mild anterior knee pains were found in 8 patients. For 4 young patients with open epiphysis, the cannulated screws were removed 10-12 weeks post operation. No growth disturbance was detected for these 4 patients at final follow-up. Conclusion Arthroscopic fixation of fracture of the tibial intercondylar eminence with cannulated screw is a simple, safe and effective procedure suitable for both children and adult patients.

Objective To introduce the Bernese periacetabular osteotomy through ilioinguinal approach for the treatment of adult acetabular dysplasia. Methods From October 1997 to April 2001, 51 patients(53 hips) with acetabular dysplasia were operated upon with Bernese periacetabular osteotomies through ilioinguinal approach. The mean age of the patients at the time of surgery was 30.6 years(range, 13-48 years). Male∶female= 1∶10. Preoperatively, the average duration of the symptoms was 3.4 years(3 months to 15 years), the range of motion(ROM) of the hip was normal in most patients. Average CE angle was 1.1?(?15?-15?); the Tonnis osteoarthritis grade was Ⅰto Ⅱ. Fifty three percent of the hips had Shentons line broken. Results Twenty four hips had 12 to 38 months followed up. Most patients were pain free; the hip ROM remained normal. Harris hip score increased from 79.8(64-83) pre operatively to 93.8(75-100) post operatively. CE angle increased to 40?(20?to 60?). Shentons line broken rate decreased to 33%. The complications include: 1 femoral nerve damage, 1 bladder malfunction and 2 skin incision hernia. Conclusion The Bernese periacetabular osteotomy through ilioinguinal approach is a safe and efficient procedure for the treatment of adult acetabular dysplasia. The deformities could be easily corrected, the anatomic relations could be restored nicely, the pelvic ring and the abductor muscles are reserved. The post operative recovery is fast, and it is efficient to prevent the development of osteoarthritis of the hip joint.
