Objective:To observe the chronological and spatial expressions of integrin ?2,?3 and ?5 which were the receptor of extracellular matrix(ECM) in the developing mouse kidney and investigate the correlation of integrin ?2,?3 and ?5 with kidney development.Methods:The expressions of integrin ?2,?3 and ?5 were examined by immunohistochemistry and stereological method.Results:The expressions of ?2,?3 and ?5 were observed from the kidney of E12d.The expression of integrin ?2 was little in the glomeruli,but obviously in renal tubules and collecting ducts,while the expression of intergrin ?3 was obviously in glomeruli.The expressions of integrin ?2,?3 and ?5 were increased gradually with kidney development by stereological analyses.Conclusion:It is suggested that integrin ?2,?3 and ?5 might play the important role in the kidney development of mouse.

Green tea is a drink made from the steamed and dried leaves of the Camellia sinensis plants.Green tea contains a number of bioactive chemicals,including polyphenols that exert anticancer and antioxidant properties.Many studied have shown that green tea polyphenols have neuroprotective effect in cerebral ischemia through the mechanisms of antioxidant,antiapoptosis,and reducing brain edema.

The fresh cadavers were injected with A. B. S into the popliteal arteries. We have studied the micro-vascular structure of this skin area under scanning electron microscope. There are 5 layers of the vascular network in this skin area. They were formed by the small branches coming from either the direct or indirect cutaneous arteries. The 5 layers are as follows: The capillary network of the papillary layer. The vascular network of the subpapillary layer. The deep dermal network. The network in the subcutaneous tissue. The network in the deep fascia tissue. It is clear that each layer of the vascular network has it's -own special character.

The vascular morphological character of the microcirculation in the nail bed of the toe have been studied with the scanning electron microscope. Three types of vascular network were identified: 1) The blood vessels at the proximal two fifth of the nail bed were parallelly arranged. 2) At the middle two fifths of the nail bed, the blood vessels interwoved with each other and formed the polygonal vascular networks. 3) At the distal one fifth of the nail bed there were only a few vascular loops running in a slanting position. These loops were connected with the vascular network from the papillary layer of the skin of the toe.

Objective To observe the effect of Lipo PGE1 and Mecobalamine and Ginkgo-dipyidamolun in the treatment of dia-betic peripheral neuropathy. Methods 60 Patients with diabetic peripheral neuropathy were divided randomly into two groups; the control group (30 cases) and the treatment group (30 cases). The patients of the treatment group were given with Lipo PGE1 100 ?g dissolved in 0.9% normal saline solution 100ml once a day intravenously, and given mecobalamine 500 ?g once a day intramuscular, and given Ginko-dipyidamolum injection 20ml dissolved in 0.9% normal saline solution 250ml once a day intravenously; and in the control group were only given with mecobalamine 500?g once a day intramuscular. Nerve conduction velocity (MNCV and SNCV) in two groups of patients was observed after 14 days treatment. Results After treatment for 14 days, the subjective symptoms and signs were significantly improved with a total effective rate of 86.7% in the treatment group versus 56.7% in the control group. Compared with the control group, the total effective rates of treatment group was significantly higher (P

OBJECTIVE: To explore the way to develop online pharmacy in China. METHODS: The online pharmacy was compared between China and the USA in respect of authentication, qualification of enterprises, distribution of medicines, management scope, payment, and protection of consumers' interest; and the implication of the development of the USA online pharmacy for China was analyzed. RESULTS & CONCLUSIONS: In the development of online pharmacy, China should draw experiences from the USA to introduce multiform management model, carry out multi- level online drug quality control, and to establish measures such as the compensation system for the drug induced sufferings.

Objective To assess the changes in blood coagulation induced by intraoperative blood salvage and reinfusion. Methods Thirty-six ASA I - II patients aged 15-63 yr undergoing elective major orthopedic surgery were paired according to their sex and type of surgery. The paired patients were randomly allocated to either autotransfusion group (study group) or homologous blood transfusion group (control group). Patients with malignant tumor were excluded. Anesthesia was induced with propofol, fentanyl and succinylcholine and maintained with isoflurane inhalation supplemented with intermittent iv boluses of fentanyl and vecuronium. During operation deliberate hypotension was induced with 0.01% sodium nitroprusside. Systolic blood pressure was maintained at (90?5) mm Hg or reduced by 30% of the baseline systolic blood pressure. During operation lactated Ringer' s solution was infused at a rate of 10 ml?kg-1?h-1 . In both groups, blood loss was replaced by equal volume of gelatine. Hct was maintained above 25% , CVP at 6 - 10 cmH2O and urine output above 50 ml? h-1 . In autotransfusion group, shed blood was collected and heparinized. Red cells were separated and washed for reinfusion. In control group red cell concentrate was infused. Hb, Hct, platelet count (PLT), prothrombin time (PT), activated partial thromboplastin time (APTT), plasma fibrinogen concentration, and thrombin time (TT) were determined and thromboelastography (TEG) was performed before operation (T0 ), before blood transfusion (T1 ), 1 h after blood transfusion (T2) and 24 h after operation (T3) .Results The two groups were comparable with regard to age, sex, duration of operation, blood loss [ (1030 ?610) ml vs (989?586) ml] and the amount of crystalloid and colloid infused during operation. In autotransfusion group Hb decreased significantly after hemodilution. There was no significant difference in PT, APTT, FIB concentration and TT between the two groups. TEG showed that reaction time (r) increased significantly after hemodilution in autotransfusion group as compared with the preoperative baseline value (T0) but there was no significant difference in TEG parameters including r time between the two groups. Conclusion Intraoperative blood salvage and reinfusion induce no significant effects on blood coagulation as compared with allogenic blood transfusion.

Objective It has been shown that strong acute stress or long-term chronic stress significantly affects learning and memory. The aim of this study was to investigate the effects of chronic pain on learning and memory and morphological structure of hippocampus in neonatal rats.Methods Sixty SD rats aged 7 days were randomly divided into two groups : (A) chronic pain group ( n = 30) in which 0.5% formalin 0.1 ml was injected subcutaneously into plantar region of hind paw every day for two weeks and (B) control group (n = 30) in which the plantar region of hind paw was touched with cotton-tipped swab every day for 2 weeks instead of subcutaneous injection of formalin. Morris water maze performance was used to test learning and memory. The number of granule neurons in dentate gyrus and pyramidal neurons in CA3 were counted. Results The mean latency period in the Morris water maze intelligence test was significantly longer in chronic pain group than that in control group ( P
