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.

OBJECTIVE:To study the pharmaceutical human resources management and new management modes.METHO_DS:Survey and analysis were based on the relevent literature and combined with the actual situations of human resources man_agement of pharmaceutical enterprises in China.RESULTS & CONCLUSION:Only by raising the level of human resources management and practicing new management modes,will the pharmaceutical enterprises get sustained benefit of the company and society.

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

Circulating tumor cells (CTCs) detections have unique advantages in the real-time personalized medicine of patients with tumors.The rarity and heterogeneity of CTCs in peripheral blood pose great technical challenge for CTCs researches.Most of technologies for detecting CTCs have been developed to enrich CTCs by virtue of physical properties or specific biological features of the cells at first,then genotype or phenotype analysis are performed to count or characterize CTCs.Advances in molecular analysis of single cells enable CTCs detections to provide more accurate and comprehensive information.Biological processes during CTCs invasion and metastasis such as epithelial-mesenchymal transition and clustering should to be considered seriously to promote the clinical applications of CTCs detection.

Objective To evaluate the feasibility and safety of using continuous spinal anesthesia (CSA) in high risk elderly patients undergoing lower abdominal or lower extremity surgery. Methods Sixty-four ASA III or IV patients aged 70-101 yr weighing 38-55 kg undergoing lower abdominal or lower extremity surgery were randomized to receive epidural anesthesia (EA) (n = 32) or CSA ( n = 32). The patients were complicated with cerebral embolism and/or hypertension, coronary artery disease and/or COPD and/or diabetes mellitus. The patients were unpremedicated. EA was performed at I2.3 or L1.2. A test dose of 2 ml of 2% lidocaine was given. When no signs of spinal block was observed, 1 % ropivacaine was given in small increments until the block height reached T6-8 . CSA was performed at L3,4 using Spinocath (B. Braun). A 2-cm catheter segment was left in subarachnoid space. 0.5% bupivacaine was given in 0.5 ml increments every 3 min until satisfactory block level was reached. The onset time of anesthesia was recorded. The degree of motor block was assessed using modified Bromage scale. Arterial blood samples were obtained before anesthesia (T0 , baseline), when satisfactory block level was reached ( T1), 1 h after skin incision (T2) and at the end of operation (T3) for determination of lactate concentration. The amount of ephedrine and innovar ( droperidol-fentanyl mixture) used during operation and the recovery of motor function of lower extremities were also recorded. Results The demographic data including sex, age, height, body weight, ASA physical status and types of operation were not significantly different between the two groups. BP and HR were significantly decreased after anesthesia as compared to the baseline values at T0 in group EA, whereas in CSA group there were no significant changes in BP and HR after anesthesia. Significantly more patients received ephedrine in EA group (98% ) than in CSA group (15%) and the mean dose of ephedrine was significantly higher in EA group [(34.5?3.1) mg] than in CSA group [(4.3?0.5) mg ]. The onset of block was significantly faster in CSA group than in EA group. Motor blockade was less intense in EA group as assessed by modified Bromage scale. Analgesia was more satisfactory in CSA group and less patients received innovar during operation in CSA group (20% ) than in EA group (51% ). The recovery of motor function of lower extremities was faster in CSA group than in EA group. Blood lactate was significantly higher at T1 , T2 , T3 in EA group than in CSA group. No late complications related to CSA was observed. Conclusion CSA is safe and effective and provides better analgesia with better hemodynamic stability and faster onset of block than EA in elderly patients.

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.
