[Objective]To observe the surgical treatment for the huge disc herniation of C3、4.[Method]Sixteen patients with huge disc herniation of C3、4 were operated upon with combined posterior decompression of expansive open-door laminoplasty with anterior decompression,bone graft and plate fixation.After operation,neurological findings,height of the interbody space and fusion rate of the space were observed.[Result]All the patients were followed up for an average of more than six months,all of them did not get secondary nerve injuries in operation,neurological function were improved obviously and all the affected interbody space got solid fusion.Based on the standard of Odom,50% of the patients were very good,25 % good,25 % general,and the effective rate was about 100%,excellent rate was about 75%.[Conclusion]The combined posterior with anterior decopression and interbody fusion for treatment of huge disc herniation of C3、4 has advantage of more security in removing the prolapsed disc,improvement of the interbody fusion rate,keeping the height ofinterbody space.This procedure is one of the effective operative methods in the treatment of huge disc herniation of C3、4.

Based on the development of ethics of laboratory animal in our and foreign countries and the related problems in our country, the necessity and feasibility of construction of the ethics censorship sys-tem about the laboratory animal were discussed and some adviees were raised to promote administration of la-boratory animal.

Aim To establish a set of consummate evaluation methods of animal models which are with syndromes of traditional Chinese medicine.Method By means of 2,4-dinitrophenol-induced fever syndrome model for the entry point,making use of meta bonomics as the platform,through analyzing metabolic fingerprint data of rat urine in the control and model group and metabolome of rat urine in model group at different time intervals,to approach the evaluation methods of animal models.Results Through research by metabonomics,the results showed that 2,4-dinitrophenol-induced animal models consisted with clinical fever syndrome of traditional Chinese medicine.Conclusion Metabonomics can be used for evaluation studies of animal models which are with syndromes of traditional Chinese medicine.

MTH1 (MutT Homolog1 )as MutT homologous en-zyme,is a nucleotide pyrophosphatase,mainly involved in DNA damage repair process,especially plays an important role in the process of DNA replication in tumor cells.Recent studies have found that MTH1’s function is responsible for the development of a variety of tumors.Studies have shown that,MTH1 can remove tumor cells’oxidative DNA elements detrimental to the function-al structure,protecting tumor cell division and proliferation, maintaining tumor cell survival,however,normal cells do not need MTH1.Therefore,MTH1 may be only closely associated with abnormal cell growth.This makes MTH1 as therapeutic tar-gets that have been paid much attention.This article reviewed the relationship of MTH1 and tumor,discussed the mechanisms of MTH1 in tumor growth MTH1 and tumor treatment,so as to provide reference for clinical research and treatment of tumor.

Tumor necrosis factor receptor-associated protein 1 (TRAP1),as one of the main members of the heat shock protein 90 family, resists oxidative stress-induced apoptosis as well as predominantly maintains the integrity of mitochondria and cellu-lar homeostasis. Abnormal expression of TRAP1 was herein closely related to the onset and progression of a wide variety of tumors. As a key regulatory factor mediating energy metabolism within tumor cells, TRAP1 may be able to kill them by interfer-ing with such metabolism. More importantly, the abnormal ex-pression of TRAP1 played a less important role in normal cells, allowing TRAP1 to be a particularly attractive target as it can be used in tumor treatment or interference. The relationship be-tween abnormal expression of TRAP1 protein and tumor onset was reviewed. Besides, the mechanism by which disordered TRAP1 protein expression induced tumor formation was postula-ted, which may provide references for future research and clini-cal treatment.

Aim To discuss the impact of important ac-tive ingredient of garlic diallyl sulfide———DATS on platelet activating factor (PAF ) mediated melanoma metastasis and its mechanisms.Methods ①MTT was used to test the effect of different concentrations of DATS on B16F10 and A375 melanoma cell growth number;②Scratch test and transwell were employed to test the effect of different concentrations of DATS on B16F10 and A375 melanoma cell migration;③ West-ern blot was used to test the effect of DATS on expres-sion of MMP-2,ERK,p38 induced by PFA;④Intrave-nous injection of tumor metastasis model was used to check the inhibition of DATS in PAF-mediated melano-ma metastasis.Results B16F10 cells relative growth rate fell to 73.21% and 48.78%,respectively,when DATS concentration reached 50 and 100 μmol·L-1 . DATS inhibited the levels of PAF-induced migration of melanoma cells B16F10 and vertical migration signifi-cantly,and inhibited B16F10 cells migration induced by PAF through inhibiting the expression of MMP-2, paxillin protein,FAK and other proteins.Conclusion DATS can significantly inhibit PAF-induced tumor metastasis, which is related to the inactivation of MAPKs.

Objective To explore the differences of the joint function and the patient's satisfaction between two different methods to reconstruct limb length for unilateral Crowe Ⅳ developmental dysplasia of the hip (DDH).Methods The clinical controlled study were used.21 cases with unilateral DDH Crowe Ⅳ treated with total hip arthroplasty were divided into 2 groups randomly.The patients in the first group were reconstructed the limb with the compensatory length and those in the second group were did with the real length.The patients were followed up 10 years.Two independent sample t-test was used to compare these two operations.Harris scores and SF-36 scores were used in the test.Survival analysis with Kaplan-Meier method was involved in the survival of the prosthesis and then test with Log-rank test.X-ray films of different period were compared to confirm the prosthetic loosening.Results Seventeen patients were followed up 8-10 years.There were no significant differences both in Harris score and most of the SF-36 scores at the median follow-up of 10 years.The item mental healthy of SF-36 expressed significant difference.Five patients required revision.There were 10 cases suffered with polyethylene wear,6 cases with severe osteoporosis in greater trochanter,and 3 cases with osteolytic reaction.Conclusion There are no significant differences between the two surgical method in the survival rate of prosthesis and the joint function in the median follow up.The satisfaction of the control groups is lower than the trial groups both at the early stage after the operation and the median follow up.The revision rate between the two groups is similar but the reason is different.

In this article, the authors expounded the necessary and problems of animal experiment post-ap-proval monitoring ( PAM) , which included who should do PAM, how to do PAM, and what the PAM can do. The authors also exposed the following suggestion: formulating the detailed rules, regulations and SOP, strengthening the training of PAM team member and animal experiment personnel, and monitoring the whole process of animal protocol review using the software.

Tumor metastasis is one of the most important biologi-cal characteristics of malignant tumor, and it is also the main factor resulting in poor prognosis and leading to failure of treat-ment. In recent years, studies have shown that the extracellular matrix ( ECM) of tumor microenvironment plays a critical role in tumor metastasis. Tumor ECM fibrogenesis could form the cross-linked network structure, which not only provides nutrition and support to tumor, also it is necessary to tumor growth and inva-sion. These research results indicate that blocking ECM fibro-genesis may exert an inhibitory effect on tumor metastasis. Therefore, targeting ECM fibrogenesis has become a particularly attractive strategy as it can be used in the treatment of metasta-sis-related diseases. The ECM fibrogenesis in tumor is reviewed in this paper as well as the treatment strategies on tumor metas-tasis by targeting ECM fibrogenesis, which may provide refer-ences for follow-up research and clinical treatment.
