Objective To establish the cell model of restenosis in vitro and investigate the effects of fenofibrate on the prevention and treatment of the restenosis.Methods Human umbilical vein endothelial cells(HUVECs) were cultured in vitro.The study was designated to 5 groups:(1) control group,(2) LPC group,(3) low-concentration fenofibrate(10 ?mol/L) group,(4) midium-concentration fenofibrate(50 ?mol/L) group,and(5) high-concentration fenofibrate(100 ?mol/L) group.Proliferation and apoptosis of HUVECs were assessed by MTT assay,flow cytometry(FCM) and fluorescence microscopy respectively.Results Compared with the control group,LPC could inhibit the growth and induce apoptosis of HUVECs as well as decrease NO production in HUVECs.Fenofibrate could increase the proliferation and decrease the apoptosis of HUVECs,and also enhance NO production of HUVECs.Conclusion Fenofibrate could improve proliferation and reduce apoptosis and enhance NO production of HUVECs through lysophosphatidylcholine,which may be an important route for fenofibrate to prevent and treat the restenosis after percutaneous coronary intervention.

Shan Qi soy has busting bags, bacteria sum overproof, continue acidification and other problems occasionally during the storage. It's probably caused by the Lactobacillus continue growth in the soy. We tried expounding the relationship between growth and producing acid when Lactobacillus growing in the thin fermented material.

Objective:To do the research on the layout and construction preparation for 3.0T high-field nuclear magnetic resonance equipment room, greatly shorten the construction time and save money for hospital by the safe and convenient usage. Methods: According to the specific characteristics of hospital sitting in full consideration of transportation and distribution, ventilation, bearing, electromagnetic interference and so on, we implement gradually, were ready to work in the construction. Results: Computer room location requirements bearing within 10 tons, magnets, center of 3 m in ferromagnetic material to do assessment, and moving around the car and the transformer must be beyond 3G line, required a special transformer and the capacity of more than 150 kVA. Equipment grounding resistance is less than 2 ohms, shielding room of insulation is greater than 1000 ohms. Super tube is higher than 3.8 m above the ground, there be no air conditioning air inlet. Water-cooled machine well ventilated, northern region need to get the winter outdoor antifreeze. Exhaust air change per hour between magnet design of not less than 12 times. Conclusion: Hospital construction for large equipment and ancillary equipment is installed in the process of each link to match reasonably, pay attention to the collaboration between different units and at the same time. Reasonable equipment layout and construction preparation is the guarantee of equipment installation smoothly.

Objective To observe the reparative response and expression of basic fibroblast growth factor (bFGF) protein in the rotator cuff subjected to subacromial impingement. Methods Subacromial impingement of the infraspinatus tendon was experimentally created in 50 male SD rats by thickening the undersurface of the acromion with one platelike bony transplantation of the ipsilateral scapular spine. The contralateral shoulders that had undergone a sham operation were used as controls. The rats were sacrificed at 3, 7, 14, 28, and 56 th day, the whole shoulder joint was removed for detecting bFGF protein and the reparative response in the impinged infraspinatus tendon. Computer image analysis system were used to monitor the expression intensity and numbers of positive cells of bFGF protein. The OD scores and the size of area represent the expression intensity and numbers of positive cells respectively. Results All rats with experimental subacromial impingement showed an infraspinatus tear on the bursal side of the tendon. The shoulders in the control group were found intact without any alteration. There was proliferating cells in the fragmented tendons and vascularised connective tissue covering the area of ruptured area, whose source was the subacromial bursa. Few tenocytes and bursal cells expressed bFGF protein in unwounded tendons. In contrast, tendons subjected to impingement exhibited an increased signal for bFGF protein in both resident tenocytes concentrated along the epitenon and infiltrating fibroblasts and inflammatory cells from the subacromial bursa. Conclusion The bFGF protein is upregulated during tendon healing and the subacromial bursa is the main source of both bFGF secreting and rotator cuff repair; one should preserve as much as possible the subacromial bursa.

Objective To evaluate the clinical application of transendoscopic Doppler ultrasonogra-phy in various gastrointestinal diseases. Methods Transendoscopic Doppler ultrasonography was performed in 59 patients with various gastrointestinal diseases. Results The Doppler signals were detected beneath the peptic ulcer base in 29 of 39 patients (74. 4% ) . For acute ulcer bleeding and non - bleeding, the Doppler - positive rates were 87. 5% and 65. 2% , respectively, and the measured depth of vessels were 0. 49 mm and 0. 65mm (P

Objective To investigate the clinical effect of Zero-profile anterior cervical interbody fusion on single-segment cervical spondylosis in the elderly, and to compare with the effect of traditional anterior cervical decompression and fusion (ACDF) with titanium plate.Methods Clinical data of elderly patients who underwent anterior cervical discectomy and fusion operation (one-or two-level) in our department from June 2009 to March 2014 were retrospectively analyzed.The 49 patients who took anterior cervical interbody fusion with the Zero-profile cage were considered as the Zero-P group, and the other 60 patients who received ACDF with titanium plate as control (ACDFP group).The operation time, blood loss, Neck Disability Index (NDI) score before and after operation, Cobb angle of the cervical spine and Cobb angle of the operated segment before and after operation, the fusion rate 1 year after operation, the dysphagia rate after operation according to Bazaz index were recorded and assessed.Results The operation time and blood loss had no statistical difference between the two group (P＞0.05 for both).The NDI scores were declined in the two group after operation as compared with before treatment (P＜0.05 for both), while there were no statistical difference in NDI score between the two groups (P＞0.05).The Cobb angle of cervical spine had little improvement 1 day after operation as compared with before operation, and improved significantly 3 month after operation in the two group.The Cobb angle of operated segment (Cobb S) was reduced 3 months in the two group after operation as compared with before treatment, and the Cobb S was declined much more in Zero-P group than in control group (P＜0.01).There was no statistical difference in the number of patients with successful fusion between the two group (46 cases vs.56 cases, x2 =0.08, P＞ 0.05).Conclusions The clinical effect of Zero-profile anterior cervical interbody fusion is equivalent as the traditional ACDFP.Zero-profile anterior cervical interbody fusion has less exposure and blood loss, which is more suitable for the elderly patients with cervical degenerative disease.

Objective To investigate the value of urine liver?type fatty acid?binding proteins(L?FABP) for early diagnosis and progress predicting of acute kidney injury(AKI)after lung transplantation. Methods Urine L?FABP and Scr blood samples in perioperative periods of 119 lung transplant recipients (hospitalized between 2013?2014)were involved in the research. Patients were divided into AKI group and non?AKI group according to KDIGO. Changes in urine L?FABP and Scr of two groups at various time points were recorded. Results Of 119 patients,57 developed AKI after surgery. Urine L?FABP from 0 h to 48 h in the two groups increased significantly, and the difference at 6 h to 48 h between the two groups is significant. In terms of diagnostic value,ROC area of urine L?FABP at 6h is 0.818. When 2254.52 ng/mg Cr was taken as diagnostic dividing line ,sensitivity and specificity was 0.782 and 0.814. In predicting AKI progression ,AUC below AUC of urine L?FABP 0.852. When 4313.17 ng/mgCr was taken as diagnostic dividing line ,sensitivity and specificity was 0.867 and 0.700. Conclusion Urinary L?FABP appears to be a sensitive and specific marker of AKI in lung transplant recipients ,could be a biological marker in the early diagnosis and progression tendency of AKI.
