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.

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.

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.

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 investigate diagnostic value of CTA for traumatic pseudoaneurysms (TPA) in the cavernous segment of the internal carotid artery (ICA) when they rupture into the sphenoid sinus. Methods CTA of 7 patients with TPA in the cavernous segments of ICA verified by DSA were retrospectively analyzed. All the patients were performed CTA scanning. The post-processing techniques included VR,MIP,MPR, and CPR. Results All the CTA images of 7 patients showed irregular mass in the sphenoid sinus with obviously enhancement in the same phase to ICA, which communicating with ICA in wide base. The peripheral area of the mass showed no enhancement. The size varied from 3 mm × 2 mm × 1 mm to 33 mm × 30 mm × 27 mm. The adjacent lateral wall of sphenoid sinus showed fractures in all cases. TPA located at anterior-knee segments of cavernous ICA in 6 cases, and cavernous free segment in 1 case. All the disruptions were found at medial or anterior medial wall of ICA. Conclusions Cranial CTA is the effective non-invasive method for diagnosing TPA in the cavernous segment of ICA when they rupture into sphenoid sinus. Combined using of VR, MIP, MPR, and CPR can delineate the location and size of the sphenoid wall fracture and the ICA rupture, which help to clarify the anatomical relationship between them.

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

Objective To investigate the effects of chronic pain on spatial learning ability and the expression of neuronal cell adhesion molecules (NCAM) in hippocampus in neonatal rats.Methods Sixty newborn SD rats of both sexes were randomly divided into pain group ( n = 30) and control group ( n= 30). In pain group complete Freund' s adjuvant (CFA) 20 ?l was injected subcutaneously in the plantar surface of left hindpaw on the 2nd day after birth, whereas in control group normal saline 20 ?l was injected instead of CFA. The animals were weighed on the 3rd, 11th and 22nd day after birth. Ten animals in each group were anesthetized with intraperitoneal pentobarbital and killed on the 11th and 22nd day after birth respectively. The brains were immediately removed for determination of NCAM expression in CA3 and dentate gyms of hippocampus using immuno-histochemical staining technique. Morris water maze test was performed starting from the 21st day after birth for 8 consecutive days to assess the spatial learning ability ( n = 10 in each group) .Results The latent period before finding the hidden-plateform was significantly longer on the 1st and 4th day of the test (22nd and 25th day after birth) in pain group than in control group (P
