Using two fresh upper limbs of adult, the ABS casts of the fine vasculature about the skin, superficial and deep fascia of thenar and hypothenar were studied by scanning electron microscopy. The microvessel networks contained five layers, that is, (1) the papillary: the capillary loops aligned with the skin-print; (2) the subpapillary; (3) the profund corium: capillaries of the glomus bodies were visible; (4) the superficial fascia: the meshwork being leaf-like; (5) the profund fascia: mainly the line vessels. There is no difference about the morphologic construction of the microvessel networks between the left and the right hand, and between thenar and hypothenar.

AIM: To study the effects of body position on the physiological and pathological changes in an oleic acid-induced acute lung injury (ALI) model. METHODS: One control group and three experimental groups were set up in which the rabbits were put on supine, prone and rotation, respectively. The changes of blood pressure, heart rate and partial pressure of arterial oxygen, lung mechanics, cytokines in the course of experiment and pathologic changes were observed. RESULTS: At the end of experiment, heart rate in rotated rabbits was lower than that in prone rabbits [(176.13?26.55) beats/min vs (217.75?14.44) beats/min, P

The extraction method and structure of exo-polysoccharide from schizophyllum commune by submerged cultivation were studied. Proteins were removed com p letely from the polysoccharide by the sevag method following the isoelectric poi nt precipitation method. The purified schizophyllan was proved to be homogeneou s with molecular weight 4?10 4D by sephadex G-200 column chromatography, PAGE and HPLC. Its monomer was determined by hydrolysis, PC, GC and its structure wa s analyzed by IR, enzymolysis, periodate oxidation, the results showed that schi zophyllan was only composed of glucose and it was the ?-glucan consisting of ?-(1-3) and ?-(1-6) glucosidic linkages.

Objective:To observe the clinical effects of acupuncture plus external medicine application for cervical radiculopathy.Methods:A total of 98 patients with cervical radiculopathy were randomly divided into an observation group and a control group based on the random digital table.The observation group (50 cases) was treated by acupuncture plus external medicine application and the control group (48 cases) was treated by acupuncture alone.The patients received the treatment every day.Ten sessions made a course.Cervical spondylosis symptom scale was used to assess the cases before and after the treatment.The clinical efficacy was compared between the two groups after the treatment.Results:The total effective rate was 98.1％ in the observation group versus 87.6％ in the control group with a statistically significant difference between the two groups (P＜0.05).The cure rate was 52.0％ in the observation group versus 18.8％ in the control group with a significant difference between the two groups (P＜0.05).There was no significant difference in the score of cervical spondylosis symptom scale between the two groups before the treatment (P＞0.05).It increased with a significant difference in both groups after the treatment (both P＜0.05),while a significant difference was found in the results between the two groups after the treatment (P＜0.05).Conclusion:Acupuncture plus external medicine application is more effective than acupuncture alone for treating cervical radiculopathy.The method also effectively improves the clinical symptoms.

Objective To explore the anatomy and the adjacent of the medial malleolus,the operative approach of soluting the tibial nerve in endoscopy and the significance of making use of it in operation. Methods The five cadaver feet were dissected,the tibial nerve and the fiber diaphragm in the middle of me- dial and lateral plantar tunnels in the ten cadaver feet were soluted in endoscopic.Results The operative approach was designed on the basis of the anatomy data (the three-portal approach:The perpendicular bisetor which was the medial malleolus pointed to the medial margin of tendon calcaneus insertion was 4.5cm;The midpoint of the medial malleolus pointed to the calcaneus tubercle;The midpoint of the calcaneus tubercle to the medial margin of the first metatarsophalangeal joint).It was succeed that soluted the tibial nerve and the fiber diaphragm in the middle of medial and lateral plantar tunnels.Conclusion The operative approach on the basis of the anatomy data is design,and testfy the feasibility of exploring curved tunnel in endoscopic.

AIM: To investigate whether hypercapnia is protective against acute lung injury (ALI) in a rabbit model, and study it's potential mechanisms. METHODS: Twenty-two healthy New Zealand white rabbits were involved in this study, and randomly allocated to control group (group C), normocapnic group (group N) and hypercapnic group (group H). Oleic acid (0 1 mL/kg) was injected intravenously to establish ALI model. Lung mechanics, hemodynamics, blood-gas analysis, the content of malondialdehyde (MDA) and superoxide dismutase (SOD) activity in lung tissue were measured. Apoptosis was analyzed after 3h mechanical ventilation. RESULTS: (1) Peak airway pressure in group H was significantly lower than that in group N (P
