Shanghai Journal of Acupuncture and Moxibustion 2016;35(9):1136-1138
Cervical spondylosis is a clinical common disease. With people’s changes in living and working styles, the incidence of the disease increases gradually and there is a development trend in younger population. There are various ways to treat cervical spondylosis. This article summarizes and analyzes recent 10 years’ literature about acupuncture-moxibustion treatment for cervical spondylosis.
2.Expression of serum endothelial nitric oxide synthase in pigs following acute myocardial infarction: Influencing ways of extracorporeal cardiac shock wave therapy
Chinese Journal of Tissue Engineering Research 2010;14(9):1649-1652
BACKGROUND:Extracorporeal cardiac shock wave therapy (CSWT) can up-regulate angiogenic factors and its receptors,promote angiogenesis and collateral circulation establishment by introducing shock waves to myocardium,however,the specific mechanisms remain unclearly.OBJECTIVE:To observe the influence of CSWT on the content of serum endothelial nitric oxide synthase (eNOS) in pigs following acute myocardial infarction (AMI).METHODS:Pig AMI model was established by embolizing the distal of left anterior coronary artery.Following model preparation,pigs were randomly divided into 2 groups.In the experimental group received three CSWT at days 1,3 and 5,200 hits per point,totally 12 points,with 0.09 mJ/mm~2 energy.Pigs with simple AMI were served as the control group.The serum eNOS level was detected by ELISA method before,immediate postoperative,and at days,1,3,5,and weeks 1,2,3,and 4 after operation.RESULTS AND CONCLUSION:The eNOS level of both groups were obvious decreased at immediate postoperative than that before operation.At day 1 after CSWT,eNOS level was increased in the experimental group,which was still decreased in the control group.It revealed that CSWT play a positive effect on ischemia rnyocardium.The eNOS level reached a peak in the experimental group after 3 times of CSWT,lasted for 2-3 weeks,and began to decrease at week 4.The difference between the experimental group and control group had significance (P<0.01).The results demonstrated that CSWT can treat AMI effectively by promoting eNOS expression.
3.Model establishment of acute myocardium infarction induced by coronary occlusion versus balloon occlusion in miniature pigs
Chinese Journal of Tissue Engineering Research 2009;13(50):9913-9916
BACKGROUND: Coronary occlusion and balloon occlusion are two major methods in preparing acute myocardium infarction models. The pigs were expensive and the modeis will periorm further study,therefore,it is necessary to prepave a model with advantage of short time consuming, few trauma, and high survival rate.OBJECTIVE: To establish acute myocardium infarction in miniature pigs induced by coronary occlusion and balloon occlusion,and to compare the differences.DESIGN, TIME AND SETTING: The randomized grouping, contrast observation animal experiment was performed at the heart intervention room of The First Affiliated Hospital of Kun Ming Medical College between May 8~(th) and August 3~(rd), 2009.MATERIALS: A total of 20 Banna miniature pigs, weighing 20-30 kg, irrespective of genders, were purchased from animal department of Kunming Medical College. The animals were equally divided into embolism and occlusion groups.METHODS: In the embolism group, the balloon was implanted into distal end of anterior descending coronary via femoral artery,blocked the forward flow with 202.65 kPa pressure for 1, 2, and 5 minutes, with 60 seconds interval. The same operation was performed in the occlusion group, followed by blocked the forward flow for successive 60 minutes.MAIN OUTCOME MEASURES: Differences of modes established by 2 methods were compared by coronary opacification, ECG,myocardium zymogram, ultrasonic cardiogram and pathology detection.RESULTS: Nine pigs were survived in the embolism group, and the remained 1 pig died of coronary artery rupture. After operation, T wave inversion could be found, without ST stage raise. At day 1 after operation, correlated lead ST stage was raised 0.1-0.2 mV. The operation duration was 11 hours. In the occlusion group, 5 pigs survived, 4 pigs died of ventricular fibrillation,and 1 died without definite cause. The operation cost 24 hours, and the correlated lead ST stage was increased 0.2-0.3 mV postoperatively. Motion abnormality in infarction place was exhibited in both groups; ventricular aneurysm was formed in 3 pigs in the embolism group, and 1 in the occlusion group. Levels of creatine kinase isoenzymes serum troponin T were obviously stepped up and presented dynamic changes. The myocardiolysis was obviously showed in the infarcted areas, but the differences were no obviously in 2 groups.CONCLUSION: Both coronary occlusion and balloon occlusion can induce models of acute myocardium infarction. The coronary occlusion method is superior to balloon occlusion with few trauma, faster postoperative recover and low mortality rates.

EZH2 is the catalytic subunit of polycomb repressive complex 2 (PRC2),which represses gene expression by catalyzing lysine 27 of histone H3.It is overexpressed in prostate cancer,breast cancer,bladder cancer,gastric cancer and several other cancers.There is a close correlation between overexpression of EZH2 and progression of malignancy,invasion and migration of cancer cells.With a thorough understanding of the function,up and down stream regulatory mechanism and clinicopathological features,EZH2 will be expected to as a target and provide a new way for the treatment of cancers.

BACKGROUND:Osteoprotegerin and nitrogen monoxidum play a key role in the prevention and treatment of osteoporosis. However, the correlation of the two in inhibiting the proliferation and differentiation of osteoclasts remains unclear.
OBJECTIVE:To observe the effect of different doses of osteoprotegerin on nitric oxide production and endothelial nitric oxide synthase activity in osteoclasts.
METHODS:Tartrate resistant acid phophatase staining was used to test whether the induced cells are osteoclasts. Osteoclasts were divided into six groups:blank control group (no reagent);negative control group (DMEM);four osteoprotegerin groups (10, 25, 50, 75μg/L of osteoprotegerin). Annexinv-FITC kit and flow cytometry were used to test the apoptosis rate of osteoclasts. Real-time PCR was used to detect the expression of osteoclasts marker gene, TRAP mRNA and protein kinase K mRNA. Nitric oxide production and nitric oxide synthase activity were determined using the corresponding kits. Four osteoprotegerin groups were added with L-NAME, a kind of nitric oxide synthase inhibitor, to test the changes of the apoptosis rates of osteoclasts and the changes of the expression of TRAP mRNA and protein kinase K mRNA of osteoclasts.
RESULTS AND CONCLUSION:Osteoprotegerin inhibited the differentiation of osteoclasts and induced the apoptosis. Osteoprotegerin concentration had a positive correlation with the apoptosis rate of osteoclasts, and a negative correlation with the numbers of osteoclasts and expression of marker gene TRAP mRNA and protein kinase K mRNA in osteoclasts. Osteoprotegerin boosted the nitric oxide production and endothelial nitric oxide synthase activity, and osteoprotegerin concentration was positively correlated to the nitric oxide production and endothelial nitric oxide synthase activity. After Raw264.7 cells were in vitro cultured, osteoprotegerin and nitric oxide play a synergic role in inhibiting osteoclasts production and promoting the apoptosis. We speculate that there is osteoprotegerin/endothelial nitric oxide synthase/nitric oxide signal pathway.

Central serous chorioretinopathy( CSC) is an important cause for central vision loss. It mostly occurs in young and middle-aged men. It is a condition characterized by a serous detachment of neurosensory retina at the posterior pole and leakage from the retinal pigment epithelium ( RPE ) . Most patients with acute CSC will resolve spontaneously. However, in cases of chronic CSC with persistent serous retinal detachment, patients might develop progressive vision loss. This article was made a brief review of the current treatment methods, including laser, photodynamic therapy ( PDT ) , intravitreal anti-vascular endothelial growth factor therapy and the mineralocorticoid receptor antagonists.
