Objective:To investigate the injury on isolated cadaver testes induced by ischemia-reperfusion (I/R).Methods:13 isolated cadaver testes contributed by 13 persons were preserved under 0℃～4℃ hypothermia and then reperfused under 37℃.Histology and histochemical changes were observed.Results:4℃ cold ischemia in 18 hours only could induce trivial swelling and vascular degeneration of endothelial cells(ECs).Obvious pathologic changes occurred after 24 hours,including detachment of ECs,separation between basement membrane and seminiferous epitelium,malalignment of spermatogenous cell and edema of mesenchyme.Injury was worse along with the prolongation of cold preservation time.Changes of LDH and SDH activities were found by histochemical staining.Reperfusion following 6 hours ischemia induced tissue injury and unusual enzyme activity.All changes were more obvious after reperfusion following 12,18,24 or 36 hours of cold ischemia.Conclusion:HCA can preserve testes for 18 hours.Testes can't keep normal histological and histochemical structure beyond 24 hours of preservation under 4℃ hypothermia,and 37℃ reperfusion can make injury worse.

Objective To study the effects of the accessory deep peroneal nerve,an anomalous branch of the superficial peroneal nerve, on the diagnosis of the deep peroneal nerve injuries. Methods Ten cases (7 male, 3 female, mean age 32.8 years) of deep peroneal nerve injuries with the presence of accessory deep peroneal nerve were examined in this study. All the cases were reviewed and analyzed with regard to the basic anatomy, clinical symptoms, electrophysiological data and diagnosis. Results In the presence of the accessory deep peroneal nerve, the lesions of the deep peroneal nerve spare the function of the lateral portion or the whole of the the extensor digitorum brevis (EDB) muscle. It may result in an unconformity of the severity of lesion and its clinical symptoms as well as the electrophysiological findings. Conclusion Knowledge of this anomaly is of crucial importance in the clinical evaluation of nerve injuries of deep peroneal nerve, as well as in avoiding errors in interpreting the electrophysiological data of this nerve.

Objective To study the effect of the Riche-Cannieu anastomosis, an anomalous anastomosis between the deep branch of ulnar nerve and the recurrent branch of median nerve in the palm of the hand, on the diagnosis of patients with carpal tunnel syndrome. Methods Twelve patients (2 male, 10 female, mean age 49.8 years) with carpal tunnel syndrome with the presence of Riche-Cannieu anastomosis were tested in this study. Their clinical data including the symptoms and signs, electrophysiological findings and diagnosis were collected and discussed in relation to an anatomical review of these nerves. Results Due to the existence of the Riche-Cannieu anastomosis, the patients with carpal tunnel syndrome spared part or all of the function of the abductor pollicis brevis (APB) muscle. It may result in an unconformity of the patients′lesion degree caused by carpal tunnel syndrome and its clinical symptoms and electrophysiological findings. Conclusion Knowledge of the Riche-Cannieu anastomosis is of crucial importance in the clinical evaluation, diagnosis and treatment of carpal tunnel syndrome, as well as in avoiding errors in interpreting the electrophysiological data of the patients.

Objective;To investigate whether the traditional Chinese medicine Yisheng Injection can reduce the injury on isolated rat heart induced by cold ischemia. Methods ;18 isolated female closed colony SD rats were divided into two groups at random. In the control group, the isolated rat hearts were preserved in 0.9% sodium chlorine solution at 4℃ , while in the experimental group ,the hearts were preserved in 0.9% sodium chlorine solution containing Yisheng injection at 4℃. The specimens were harvested 2,6,12, 24,48 and 72 hours after preservation. Histochemical changes were observed in two groups. Results ;In the control group, the activities of alkaline phosphatase ( ALP) and NADPH diaphorase (NADPHD) decreased after cold ischemia for 24 hours. Lactic dehydro-genase (LDH) decreased slightly, while ALP and NADPHD decreased evidently, after cold ischemia for 48 hours. Succinic dehydro-genase ( SDH) and cytochrome oxidase ( CCO) decreased slightly, and NADPHD disappeared after cold ischemia for 72 hours respectively. In the experimental group, NADPHD, LDH and CCO decreased slightly after cold ischemia for 24, 48 and 72 hours. ALP decreased slightly after cold ischemia for 48 hours, however, SDH showed no changes, after cold ischemia for 72 hours. Conclusion : Cold ischemia can induce cold ischemia injury in isolated rat hearts, especially the vascular endothelial cells being more sensitive. Yisheng injection can reduce this kind of injury to some degree.

0.05),however,by the 12th week,there was a significant difference(3.6?0.48 vs 2.4?0.48,P0.05)in the graft vasculopathy between two groups.Conclusion: It is practicable to establish a cardiac chronic graft failure model between closed colony SD rats,and ischemia reperfusion injury,as an alloantigen independent factor,would accelerate the development of rat cardiac chronic graft vascular disease,which can save the time for establishing models.

Objective To investigate the clinical and electrophysiological characteristics of entrapment syndrome involving the median nerve's recurrent branch. Methods Fourteen cases (10 male, 4 female, mean age 34.7) of medial nerve recurrent branch entrapment syndrome were retrospectively analyzed in this study with regard to their clinical and electrophysiological data. Results Normal sensory conduction velocity ( SCV ) and normal amplitude of the sensory nerve action potential ( SNAP) were found, but there was a delay of the distal motor latency (DML) in all 14 cases. The compound muscle action potential (CMAP) amplitude was decreased in 11 cases, and normal motor conduction velocity (MCV) was demonstrated in 12 cases. Fibrillation potentials and/or positive sharp waves were detected in the abductor pollicis brevis muscle in 12 cases and in the opponens pollicis muscle in 14 cases. EMGs of the flexor digitorum superficialis and pronator quadratus muscle were normal in all 14 cases. Conclusion Electrophysiological examination could provide objective and reliable data for diagnosing and differentially diagnosing median nerve recurrent branch entrapment syndrome.

Professor LI De-lin is sophisticated in the clinical experiences of treating diabetes mellitus(DM)with traditional Chinese medicine(TCM).Based on clinical observations for many years,the key pathogenesis of DM resulted from internal organs'deficiency,endogenous heat exuberance,liquid and qi's consumption as well as blood density and turbid fluid thickness.From the knowledge above,professor LI advocated to treat DM and diseases accompanied by it with the combination of treatment based on disease and syndrome differentiation to improve the curative effects.During the specific treatments,professor LI emphasized that treatment based on disease differentiation should benefit qi,nourish yin and strengthen yang;treatment based on syndrome differentiation should strengthen vital qi and eliminate pathogenic factor.Strengthening vital qi includes to benefit qi ,nourish blood,tonify yang and supply yin.Eliminating pathogen includes to treat heat-toxicity,phlegm,dampness and depression at the same time.He advocated firstly to invigorate spleen and kidney,secondly to clear heat fire and disperse stagnated liver qi,lastly to moisten and invigorate lung.We received satisfactory curative effects both on the clinical treatments and experiments in DM and diseases accompanied by it when adopting the TCM methods of treatment based on the theory by Professor LI De-lin.
