Chinese Journal of Sports Medicine.1983;0(03):-.

Clinical observation was undertaken on patients with vertebroarterial type ofcervical spondylopathy who were treated with necktraction and manipulation, of110 patients, there were 82 men and 28 women. The average age was 56.29 yearsold. 102 of 110 patients had vertigo. In 91 patients with which vertigo wasassociated with body position, most of them also had abnormal hearing and visionand headche and hoarseness, etc. Examination: The positive rate of Jackson Test and Rotating-head Test was83.33%. The degenerative changes could be seen on the X-ray films of the cer-vical vertebrae. 55.95% of them suffered from eyeground arteriosclerosis, 40.78%hyperlipemia, 42.16%. hypertension, 36.17% ECG abnormality. Treatment: of 110 patients, 97 were treated with neck traction and manipu-lation. The average times of neck-traction of whom were 44.13, the averagetimes of manipulation 33.92. In addition, we compared one group which usedtraction and manipulation with another one that used traction and manipulationtogether with drip transfusion of dextran. Chi-spuare Test showed no signifi-cant difference between the two groups. Conclusion 1. The information in the paper indicated close relationship between verte-broarterial type of cervical spondylopathy and atherosclerosis. 2. Diagnosis of the disease could be done after excluding a few diseasessuch as Meniere's disease and hemicranie and sympathetic type of cervicalvertebrae, etc. 3. After vertebroarterial angiography, the patients suffering from the diseasetreated with surgery if conservative therapy had no effect. 4. The paper also studied the mechanism of neck-traction and manipulation on vertebroarterial type of cervical spondylopathy.

Chinese Journal of Sports Medicine.2010;(2):184-187,216.

Objective To clarify the effects of exercise- and food intake restriction-induced weight reduction on expression of ghrelin in plasma and stomach of obese rats,and to explore the role of ghrelin during weight loss. Methods 100 weaned Sprague-Dawley(SD) rats were randomly divided into control group(fed with standard chow,n= 20) and model group (two-bottle-feeding method,fed with standard chow and high-fat diet simultaneously, n=80). After 20 weeks feeding, Lee' s index of control was used as the reference of diet-induced obesity identification, and then diet-induced obese rats were randomly divided into four groups:obese control group,swimming group,food intake restriction group and swimming+food intake restriction group, eight rats in each group. Rats in swimming group underwent long-term(40 min,6 days/week for 5 weeks)swimming exercise. Calorie in food intake restriction group was restricted 1/3 of normal kcal for 3 weeks,and subsequently restricted 1/3 for 2 weeks. Swimming+food restriction group had the same intervention as swimming and food restriction group. 8 normal diet rats were also chosen as controls. After five weeks of treatments,peripheral fat mass of testis and kidney,ghrelin proteins in plasma and stomach,and ghrelin mRNA in stomach were measured. Results Gastric ghrelin protein and mRNA were significantly lower in obese control group than those in normal control group (P<0.05). However, plasma ghrelin did not decrease markedly in obese control rats(P>0.05). Compared with obese control group,weight and fat mass in all weight loss groups declined notablely(P<0.05);in swimming and swimming+food restriction groups,the expression of ghrelin protein or mRNA in plasma or stomach increased remarkably( P<0.05); in food restriction group, the level of ghrelin mRNA raised significantly (P<0.05), while ghrelin protein in plasma and stomach had not change. Conclusion The level of ghrelin increased in exercise induced weight loss,while showed no significant change in food intake restriction group, suggested that ghrelin might be involved in the process of weight loss induced by exercise.

Chinese Journal of Sports Medicine.2010;(2):181-183,191.

Objective To evaluate Janus kinase (JAKs) and Suppressors of cytokine signaling(SOCSs) expression in myocardium after endurance training. Methods 30 male Sprague-Dawley rats undertook 10 weeks grade treadmill training program and were sacrificed at 0 and 24 h respectively after the last exercise. JAK1,JAK2,JAK3 and SOCS1 ,SOCS2,SOCS6 expression in the myocardium were determined by im munohistochemistry method. Results The percentage of JAK1 positive cell significantly increased immediately after last running and recovered to the sedentary level 24 hrs after exercise;The percentage of JAK2 positive cell significantly increased immediately after last running and continuously at a higher level 24 hrs after exercise (P<0.01;P<0.05); JAK.3 showed no significant change either immediately or 24 hrs after exercise (P>0.05). The percentage of SOCS1 and SOCS2 positive cell also significantly increased both immediately and 24 hrs after exercise (P<0.01 ;P<0.05). However, the percentage of SOCS6 positive cell showed no significant change either immediately or 24 hrs after exercise(P>0.05). Conclusion Endurance training could induce different responses of JAK1,JAK2 and JAK3. The increased expressions of JAK1 and JAK2 might indicate the changes of JAK/STAT signal pathway in regulating myocardial function. The increased expressions of SOCS1 and SOCS2 after endurance training might indicate the increased exertion in regulating JAK/STAT signal pathway in cardiac muscle.

Tiebin YAN ; Binquan XU

Chinese Journal of Sports Medicine.1983;0(04):-.

Five young rabbits were divided into 5 groups (2, 4, 6, 8 and 12 week), one rabbit in each group.A special collision unit was used in the experiment by which the distal ends of the right fore legs of rabbits were struck repeatedly. Altrastructure changes of chondrocyte at the epiphyseal plate in the distal endof radius were observed in H-500 electron microscope. In two and four week groups, organaelles swelling was found such as rough endoplasmic reticulum andmitochondria, especially mitochondria swelling which showed different shapes like sausagge and racket.Space around nucleus increased, nucleus shape changed, myeline structure in the mitochondria and chroma- tin margination in the nucleus were found in the six and eight week groups. Altrastructure changes weremore serious in the eight and twelve week groups than other groups. Necrosis of chondrocyte was appearedsuch as part organaelles dissolved or disappeared, nucleus brokeu aud nucleus memberane disappeared. The results showed in altrastructure pathology that chronic collision injury can cause not only degeneration of chondrocyte in the pressure epiphyseal plate but necrosis of chondrocyte as well. It concluses that chondrocyte necrosis is related to local ischemia resulted from chronic collision injury.
