2.Investigation on spondylolysis of lumbar vertebral arch in 100 recruits before and after reinforced training
Chinese Journal of Tissue Engineering Research 2006;10(4):164-165
BACKGROUND: The incidence rate of spondylolysis of lumbar vertebral arch in recruits is higher during the training, and it affects the normal training. OBJECTIVE: To analyze the correlation of the incidence rate of spondy lolysis of lumbar vertebral arch with training and the original lesions at waist in recruits. DESIGN: A randomized sampling survey. SETTING: Department of Orthopaedics, the 97 Hospital of Chinese PLA. PARTICIPANTS: Totally 100 male recruits aged 18.7 years averagely en rolled in 2003 were involved in the survey. METHODS: The 100 recruits were followed up for the whole course, the X-ray examination at lumbar vertebrae of right, lateral and two-slope positions were observed before training and after 100-day reinforced training. MAIN OUTCOME MEASURES: The incidence rates of spondylolysis of vertebral arch, and whether there was slippage and other aggravations in those with spondylolysis before were mainly observed. RESULTS: All the 100 recruits entered the analysis of results. ① The in cidence rate of spondylolysis of vertebral arch before and after training: Be fore training, 5 cases had spondylolysis of L5 vertebral arch, and the incidence rate was 5%. At the end of the 100-day training, 8 cases had spondylolysis of lumbar vertebral arch, and the incidence rate increased to 8%. ② The results of X-ray examination before and after training: The Xray examination showed that isthmus narrowing of left and L5 vertebral arch occurred in 2 cases and 1 case respect ively, and spondylolysis of bilateral L5 vertebral arches occurred in 5 cases, including 1 case of degree I slip page before training. At the end of the 100-day training, the degree I slip page and below occurred in 3 of the 5 cases with spondylolysis of bilateral L5 vertebral arches before, another 3 cases with original narrowing of lumbar vertebral arch all had breakage. CONCLUSION: The incidence rate of spondylolysis of vertebral arch is associated with the training intensity. It suggestes that the examination of spinal cord should be reinforced in enrolled recruits, and the items of Xray examination at lumbar vertebrae of right, lateral and two-slope positions should be added.
3.The present situation of choice for supporting and bone grafting material for anterior reconstruction after debridement of spinal tuberculosis
International Journal of Surgery 2011;38(1):50-53
Tuberculosis of bone and joint most commonly occurs in spine, and the main treatment method is anterior debridement, bone grafting and internal fixation. Autologous bone is still considered the "gold standard" when the anterior reconstruction of spine after debridement is needed. Allogeneic bone, artificial bone and artificial intervertebral support bodies such as titanium mesh and some biological materials also have a broad clinical application, but still can not completely replace the autologous bone because of their defects. In the aspect of internal fixation, anterior fixation has become a conventional method for the patients who suffer from active spinal tuberculosis and need anterior debridement of the focus, because this method can provide good support. This review summarizes the present situation of choice for supporting and bone grafting material for anterior reconstruction after debridement of spinal tuberculosis.

5.Advances in diagnosis and treatment of Takayasu arteritis in children
International Journal of Pediatrics 2013;(3):297-300
Takayasu arteritis (TA) is a devastating vasculitis of the aorta and its major branches,coronary and pulmonary arteries.The clinical manifestations in children are less specific than in adnlts:the disease in children presents with fever,arthralgias,vomiting,weight loss and hypertension.Conventional angiography,which is recognized as the golden standard in evaluating vascular lesions in TA,combined with computer tomography angiography (CTA),magnetic resonance angiography (MRA),ultrasonography,could not only provide important information for early diagnosis,but also detect disease activity.New immunosuppressive agents and biological therapies,such as TNF-a blocking agents,have been verified to be effective although corticosteroids and conventional immunosuppressive agents are still basic treatment.
6.Exercise and adenosine triphosphate-sensitive potassium channel
Chinese Journal of Tissue Engineering Research 2014;(46):7492-7497
BACKGROUND:In the condition of exercise physiology, adenosine triphosphate-sensitive potassium (KATP) channel plays an important role in many aspects, such as regulation of coronary artery tension, exercise-induced myocardial protection effect and delay of skeletal muscle fatigue. OBJECTIVE:To review and investigate the role of KATP in exercise in order to provide theoretical reference for understanding mechanism underlying exercise regulation of body’s metabolism. METHODS: A computer-based online search of PubMed and VIP databases was performed for articles related to molecular structure, biological function and regulatory role of KATP as wel as correlation of KATP with coronary artery, myocardium, skeletal muscle fatigue and exercise ability published from January 1991 to June 2014. The keywords were “KATP channels; adenosine triphosphate; sports; myocardium; ion channels” in English and Chinese, respectively. Finaly, 42 relevant articles were included in result analysis. RESULTS AND CONCLUSION: Coupling with celular energy metabolism and cel membrane excitability, KATP channel is one of the effectors for myocardial protection in response to various physiological and pathological stresses. Prolonged endurance training can increase the expression of skeletal muscle and myocardial KATP, which may be an adaptive performance of the myocardium and skeletal muscle in response to exercise stress. KATP may participate in regulation of coronary blood flow. Myocardial KATP plays an important protective role for aleviating myocardial ischemia-reperfusion injury induced by exercise. When skeletal muscle fatigue occurs, the activation of KATP is helpful to prevent muscle fiber damage and cel death due to excessive consumption of ATP, in favor for the fast recovery from fatigue. The relation between KATP and exercise ability stil needs further research.

Chinese Journal of Behavioral Medicine and Brain Science 2015;24(10):888-891
Objective To explore the effect of the different doses of oxytocin(OXT) on stress model aggressive behaviour in Wistar rats.Methods According to random number table,40 pregnant rats were divided into experimental stress groups (A, B, C) and control group(D) with 10 samples in each group.Before forced swimming test, rats in experimental groups (A, B, C)were given OXT via intraperitoneal injection with 0.3 mg/kg, 1.0 mg/kg,2.0 mg/kg;rats in group D were given equal volume of normal saline in the same way.At the 3rd day all rats were tested with maternal aggression,including mothers' following indices as total aggression times,biting times,pinning times,attack latency and duration of attack.Elevated plus maze (EPM) test was applied to analyze the behavioral changes.Results In terms of the duration of attack and attack latency,the indexes of group A and group D were significantly different from relevant data ((147.60±23.92) s and(79.70±9.88) s, P<0.05), while other indexes had no difference(P>0.05).The duration of attack and attack latency had a significant difference ((3.10±0.87) times, (13.60±5.14)times, (91.30±9.74)s and(167.20±30.02) s, P<0.01) between group B and group D except total aggression times(P>0.05).Group C and group D in given indexes had significant differences showing (6.40± 1.34) times, (15.10±4.35) times, (23.70±3.46) times, (49.80± 5.53) s and (215.60± 39.55) s (P<0.01).Group A and group B in given indexes had significant differences (P< 0.05);and group B and group C had a significant difference (P<0.01)except pinning times(P>0.05).In EPM ,the open arm entry ratio and the open arm time ratio of both group A and group D were significantly different from respective percentage (0.47±0.13) and (0.13±0.05) (P<0.01).The significant difference was found in group B and group D(P<0.01);group A and group B had a statistical difference(P<0.05);there was no difference in both groups in open arm time ratio(P>0.05).Conclusion Oxytocin potentially mediates maternal aggression by attenuating stress, and improves the intimate bonding between mother and pups,which means dose dependency of OXT in this process.
