1.Study on Neural Co-activation during Human Upper Limb Muscle Fatigue Based on Surface Electromyography
Chinese Journal of Sports Medicine 2017;36(4):290-295
Objectives To observe the co-activation phenomenon during exercise fatigue induced by the proximal muscles on the upper limbs.Methods Sixteen undergraduates not majoring in sports participated in this study,and their left arms were chosen as the observed arms and right arms were selected as the weighted arms.The weighted arm was alternatively in the state of relaxation without any load and fatigue after bending and extending elbow joints to uphold a 5 kg dumbbell.However,the observed arm kept weighing a 4 kg dumbbell with 90 degrees elbow flexion until the muscles were exhausted.The surface electromyography of biceps brachii and triceps brachii of the observed arms was measured using the ME6000.And the integrated surface electromyography (IEMG),root of mean square (RMS),mean power frequency (MPF)and median frequency (MF)were further analyzed.Results The IEMG and RMS of biceps brachii and triceps brachii of the observed arms increased gradually after the exercise began (P<0.05)regardless of in the relaxed state or in the in the state of weighing a 5 kg dumbbell for the weighted arm,but in the state of weighting a 5 kg dumbbell the IEMG and RMS increased more significantly (P<0.01),Meanwhile the electrical activities of the triceps brachii as an antagonistic muscle were intensively inhibited.The changes of MPF and MF of biceps brachii in the observed arms were more significant in the state of exercise fatigue than in the relaxed state (P<0.01),but without such an impact on the triceps brachii.Conclusions The fatigue in one arm can trigger contingent changes in sEMG time domain and frequency domain indexes of its contralateral parallel muscles,suggesting that sEMG changes of upper limb proximal muscles have the co-activation effect.

5.Necessity and feasibility of screening for colorectal cancer in China.
Chinese Journal of Gastrointestinal Surgery 2011;14(1):16-18
Incidence and mortality of colorectal cancer has increased significantly in recent years. Screening for colorectal cancer is the most effective method to decrease mortality. Colorectal adenoma is the precancerous lesion of colorectal cancer and can be detected through colonoscopy, which is the crucial in the early diagnosis and early treatment for colorectal cancer. The first step of screening is the selection of target population and the second step is colorectal examination. The selection of candidate for screening has direct effect on the efficacy of screening. The methods in common use include fecal occult blood test, questionnaire for high risk factors of colorectal cancer, colonoscopy, sigmoidoscopy, and CT virtual colonoscopy. Among those, colonoscopy is the most reliable method and widely used in the screening for colorectal cancer.

Chinese Journal of Postgraduates of Medicine 2016;39(5):397-400
Objective To explore the microsurgical technique of ependymoma in conus medullaris and cauda equina. Methods Sixteen patients with ependymoma confirmed by pathology after operation in conus medullaris and cauda equina were analyzed retrospectively for their clinical manifestations, imaging features and microsurgical treatment. Results All patients conducted preoperative MRI, and total tumor resection was achieved in 14 patients and subtotal resection in 2 patients. The pathological examinations confirmed the tumor as myxopapillary ependymomas in 7 patients. Symptoms of fifteen patients were alleviated significantly after operation. One patient had urine retention after operation and was gradually restored 1 week after operation. All patients were followed up for 1-3 months, and there was no case of recurrence. Conclusions Ependymoma in conus medullaris and cauda equina is rare and easily misdiagnosed, with no specific clinical manifestations. MRI should be conducted as soon as possible to identify the diagnosis. Microsurgical treatment is an effective method for ependymoma in conus medullaris and cauda equina.
