BACKGROUND:Previous studies with regard to male track short-distance cyclists are concentrated on the descriptive and comparison studies of morphological characteristics of athletes Up to now,few studies report the relationships between morphological characteristics and sports performance in men 1-km cyclists.OBJECTIVE:To explore an effective morphological index for evaluating physical stamina level of men cyclists in 1-km time trials,and to establish morphological models and evaluation standards for men cyclists in 1-km time trials in China.METHODS:Totally 17 men who had prepared for the 1-km cycling time trials of the fifth cycling city sport meeting in Taiyuan were examined.With the methods of step by step regression,gray correlation,measurement and evaluation theory,the morphological characteristics of these excellent cyclists were explored,and utilized in establishing morphological models,single-grading table and the ranking evaluation criteria.RESULTS AND CONCLUSION:The typical indexes of excellent 1-km men cyclists were body height and fat-free body weight.The morphological characteristics of these excellent cyclists were as follow:tall,long leg and Achilles tendon;high foot arch;heavy body weight and fat-free body weight;as well as thick thigh The present study established the evaluation model of the morphological characteristics and evaluation standards for 1-km men cyclists

[Objective]To investigate the clinical result of the Chinese traditional medicine combed with western medicine treatment for proximal humerus malunited fracture.[Method]Twenty-nine patients including 24 men and 5 women with malunion of proximal humerus were treated with the locking proximal plate.The average age of patients was 41.6 years old(from 21 to 53 years old).According to Neet classification on X ray,20 cases were two-part fractures and 9 cases were three-part fractures.These patients were treated by combination of Chinese traditional and western medicine,with the help of the functional training.All patients with proximal humerus malunited fracture were treated by operations with locking proximal humerus plate.A herbal bath was used to bathe after surgery.[Result]All 29 cases were available for follow-up.The average time for bony union on X ray was 9.6 weeks(from 8 to 12 weeks).Nonunion was not found in all cases.According to the Neer scoring system,there were 23 excellent cases,4 good case and 2 fair case.The excellent and good rate was 93.1%.[Conclusion]In dealing with proximal humerus malunited fracture,the advantages of the locking proximal humerus plate are minimally invasive with reliable fixation,few complication and the high bone union rate.A herbal bath can fasten recovering the function of the shoulder.Chinese traditional medicine combined with western medicine treatment can make satisfactory result and it is an effective method to recover the function of the shoulder.

Objective To investigate the clinical diagnosis and treatment of incomplete Beh et′s disease. Methods The clinical data of 52 patients (83 eyes ) with incomplete Beh et′s disease were retrospectively analysed. Visual acuity and results of examination of slit-lamp microscope, ocular fundus, and fundus fluorescein angiography (FFA) were observed and analysed. All of patients were treated by local cycloplegic, systemic treatment with glucocorticoid and cytoxan. The followed-up period was 1 year or more. Results Recurrent hypopyon or empyema of anterior chamber angle, and hyperaemia of optic papilla was found in 54 and 41 eyes, respectively. The results of FFA showed that abnormal changes were found in all of the eyes. There was vascular leakage and staining of optic papilla at the early and late stage in 83 eyes (100%), diffuse leakage of retinal capillary vessel in 83 eyes (100%), and leakage of affected branch of retinal vessel and staining of the vascular wall at the late stage in 71 eyes (85.54%).After the treatment, the disease recovered completely in 20 patients (26 eyes), recovered partly in 20 (33 eyes), and alleviated in 12 (24 eyes). No patients suffered from hypopyon or empyema of anterior chamber angle and hyperemia of optic papilla. None of the patients had oral ulcer, genital ulcer or arthritis until the last day of the follow-up. Conclusions Recurrent hypopyon, papillitis, and retinal vasculitis were the main clinical manifestations of incomplete Beh et′s disease. FFA redounds to the diagnosis of the disease and timely application of cycloplegic and systemic application of glucocorticoid and cytoxan may inhibit the aggravation of the disease effectively.

Objective To observe the effect of the application of acupuncture Jiaji points and continuous acupoints infusion of analgesic drugs at Jiajji in the treatment of postoperative pain on rat behavior through the establishment of a rat model of incisional pain .Methods 60 healthy male SD rats ,were randomly divided into sham control group ,PI group ,CSI group ,EA group and CAI group ,12 in each group .Plantar incision pain model in rats was established according to the method of Brennan ,rats in 5 groups at preoperative 1 h and 6 ,24 ,48 h after operation ,mechanical withdrawal threshold(MWT) and thermal withdrawal latency(TWL) were evaluated .Results Changes in MWT :5 groups of rats with experimental basis of mechanical withdrawal threshold values showed no significant difference among them ;comparison of the mechanical withdrawal threshold in the sham control group at each time point showed no significant difference(P>0 .05);when compared with sham control group ,MWT in PI group ,CSI group ,EA group and CAI group decreased significantly at 6 ,24 ,48 h after operation (P<0 .05);when compared with PI group ,MWT in CSI group ,EA group and CAI group increased significantly at 6 ,24 ,48 h after operation(P<0 .05);when compared with CSI group and EA group ,MWT in CAI group increased significantly at 6 ,24 ,48 h after operation (P<0 .05) .Changes of TWL :when compared with the sham control group ,TWL decreased significantly in PI group at 6 ,24 ,48 h after operation (P< 0 .05);when compared with the sham group ,TWL in CSI group ,EA group ,CAI group increased significantly at 6 ,24 ,48 h after operation (P<0 .05);when compared with CSI group and EA group ,TWL in CAI group increased significantly at 6 ,24 ,48 h after operation (P<0 .05) . Conclusion Electroacupuncture and continuous acupoint infusion of analgesic drugs at Jiaji could produce obvious analgesic effect , the analgesia effect of continuous acupoint infusion at Jiaji is better than subcutaneous analgesia .

Objective To investigate the kindergarten weigh recipe nutrients allowance and chidren health status.Methods The dietary analysis was made in kindergartens by weighing and growth development was perfonmed in 17 947 chidren.Results The nutrients allowance was different in 15 observation projects,recipe nutrients allow-ance was sufficient for 80%,nutrients allowance was not enough for 20%.Middle serious malnutrition was 0.62%,slow gowth and development was 0.67%.simpie obesity was 5.80%.anemia was 1.40%.Conclusions The recipe nutrients allowance was difference in all kindergartens.Nutrients abundant and not enough was concurrent.Simple o-besity incidence rate was much higher than middle serious malnutrition.

Objective　To explore the phenomenon of neural apoptosis after chronic compressive spinal cord injury. 　Methods　A newly designed chronic progressive compressive spinal cord injury model of rat was adopted in this study. Forty-five Wister rats were divided into mild, moderate, and severe group according to the compressive degree of the spinal cord. The Feulgen stain and TUNEL were used to investigate the apoptosis and its characteristics in different kinds of neural cells. 　 Results　Apoptosis index in moderate injury group was the highest. Apoptotic cells largely located in ventral, lateral and dorsal column of the white matter. Most of them were oligodendrocytes. Positive neuron occasionally presented in laminae Ⅲ～Ⅸ part of the sections. Most of them located in dorsal gray horn. 　Conclusions　 Apoptosis is an important event in secondary pathophysiological process of chronic progressive compressive spinal cord injury. Apoptosis is one of the reasons for neural cell death. The apoptosis of oligodendrocytos may contribute to myelin sheath disruption of white matter.

Objective To analyze pathologic features, therapeutic strategies and prognosis of patients with metastatic solid pseudopapillary tumor of the pancreas (m-SPTP). Methods Twenty five patients with m-SPTP undergoing radical resection between June 1985 and Dec 2005 were retrospectively analyzed. Kaplan-Meier analysis was used to screen out risk factors of the prognosis of m-SPTP patients.Results Twenty-three postoperative patients were followed up until Dec 2007. The follow-up rate was 92% and the median follow up time was 78 months. The 5-year overall survival rate was 82%. Kaplan-Meier analysis showed that five variables including age, tumor size, pathologic features, number of metastatic lesions and lymphatic metastasis were related to overall survival. Conclusions Solid pseudopapillary tumor of the pancreas is low-grade malignant potential with a favorable prognosis, but not for the m-SPTP.Patients of ≥40 years old, tumor size (≥6 cm), pathologic features (including presence of areas with diffuse growth pattern and tumor necrosis), multiple metastatic lesions and lymphatic metastasis have poor prognosis.
