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.

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.

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 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 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

Objective To analyze analgesics administration from July 2005 to July 2006 in emergency rooms of the First, the Second and Fourth Affiliated Hospitals of China Medical University in order to provide a reference for clinically rational administration. Method The data of 2313 prescriptions with analgesics administered during one-year period were analyzed in many respects including the overview of the prescriptions, the frequency of anal-gesics administration, the system of defined daily doses (DDDs) and drug utilization index (DUI) of narcotic anal-gesics were analyzed, and a survey of 200 patients managed with some of those analgesics was done by using ques-tionaire as they were admitted to and discharged from the emergency room. The pain intensity was evaluated by a 10-point numerical rating scale (NRS). The respondents, excluding the mute or deaf, police custody, victims of domestic violence,mental disorder and age under 14,rated the levels of satisfaction with medication for pain relief. The data of frequency and percentage of the administration of analgeics were analyzed,and the scores of NRS were evaluated with the Paired-samples t -test. Results Most of analgesics were in the form of parenteral route usage, of which anisodamine and bucinnazine were employed in large proportion, and a small number of them was in the form of tablets. Trauma was the commonest cause of pain. Of the narcotic analgesics, meperidine was the most com-monly used analgesics, and its DDDs and DUI were much lower than that of WHO limits. Of the 200 patients, 71.5% patients rated a considerably high satisfaction with scores of (7.47 ±2.21) and (5.00 ± 3. 16) by NRS before and after medication,respectively ( ( -value 23.38,P < 0.01) .The patients presenting pain intensity with a scores of 4 or greater accounted for 57.5% . Conclusions The patients suffering from pain could lie rationally treated in the emergency rooms of those three hospitals. Narcotic analgesics should be cautiously employed, and there is room for improvement in pain management practice in emergency room.

Objective To investigate the protective effects of hypereapnia on acute lung injury(ALI)in an model of rabbits in vivo,and to observe its effect on oxygen free radicals in the lung tissue in order to uncover the potential mechanisms.Method In the laboratory of pharmacology,China Medical Univereity,twenty-two healthy New Zealand white rabbits were randomly assigned to control group(Group C,n=6)with the injection of normal saline(0.1 ml/kg),and sixteen rabbits were injected with oleic acid(0.1ml/kg)intravenously,and then were randomly dirided into normocapnia group(Group N,n=8)and hypercapnia group(Group H,n=8,FiCO2=8%).Then tracheostomy was performed,and the experimental animals were ventilated for 3 hours after oleic acid or sterile normal saline administration.Lung mechanics,hemodynamics,blood-gas analysis were monitored.The rabbits were exsangninated.and the lungs and heart were taken out from the thorax.The concentration of superoxide dismutase(SOD)and malondialdehyde(MDA)in the lung tissue were assayed.Lung tissue wet/dry ratio and pulmonary permeability index were measured and histologic damage was assessed after three hours'mechanical ventilation.Results Peak airway pressure in Group H was significantly lower than that in Group N and the dynamic lung comphance Was significantly higher than that in Group N(P＜0.05).PaO2 in Group H was significantly higher than that in Group N(P＜0.05).The concentration of MDA in the lung tissue in group H was significantly lower than that in Group N(P＜0.05),and SOD in group H was significantly higher than that in Group N(P＜O.05).Lung tissue wet/dry ratio and pulmonary permeability in group H were significantly lower than that in Group N(P＜0.05).Histological tissus damage in Group N wassignificantly severer than that in Group H.Conclusions Hypercapnia induced by inhalation of high concentration of carbon dioxide(8%)plays protective role in this in vivo model of ALI.The mechanisms may be associated with enhanced SOD activity and the attenuation of lipid peroxidation in the lung tissue.
