Objective To evaluate the safety of coronary artery bypass grafting(CABG) on patients with end-stage hemodialysis-dependent renal failure.Method Two patients with hemodialysis who received CABG were reported.The features of clinical manifestation were studied.Results CHDF was preformed in two cases after operation.One patient died of hemorrhage on the third day after operation,the other patient showed relief of recurrent chest pain and improved quality of life after CABG.Conclusion Under a well-prepared dialysis program and meticulous perioperative management,CABG can be performed in dialysis-dependent patients,with increased but acceptable perioperative morbidity and mortality risks.Our initial experiences of CHDF during and after CABG suggest that the technique provides excellent electrolyte,metabolite and fluid management for the cardiac patients with chronic renal failure.

To prevent surgical risk, improve the quality of operation, and evaluate surgical doctors scientifically, it provides management experience and references.

Objective To diagnose the infection of Pseudomonas aeruginosa early. Methods Polymerase chain reaction (PCR) was used to amplify the fragment of Pseudomonas aeruginosa OprI gene. The fragment was determined by HaeⅢ and PvuⅡ digestion, and sequencing analyses. Results It showed that 96 of 223 specimens were cultured to be positive with Pseudomonas aeruginosa, 96 of which had expectant streaks. Otherwise the other specimens had no positive streaks. The procedure needed only 4 hours. The PCR products were determined by ribonuclease HaeⅢ and PvuⅡ , and resulted in two small fragments with 49bp and 112bp separately. By automatic sequencing analysis, the coincidence rate with the gene bank was 100%. Conclusions The results indicates that the OprI gene detection by PCR is a specific, sensitive and quick technique for the diagnosis of Pseudomonas aeruginosa infection.

Objective To construct a home-care service package for the urban disabled elderly that satisfy their demands and improve the efficiency of service. Methods From August to October, 2014, a total of 285 disabled (mild, medium and severe) elderly from a cluster sampling were investigated with the self-designed questionnaire about home-care demands among them. An initiatory service package was drawn to meet the demands reported by 40% of them or above. The package was consulted by a group of 15 experts using Delphi method. Results The final service package included 11, 19, 20 items of care for the mild, medium and severe disabled elderly, respectively. Conclu-sion The disabled elderly home-care package in Zhengzhou has been created based on the demands among disabled elderly.

Objective:To study the wound healing effects of the extracts of Shengji Huayu Fang with different solvents and demon-strate their important role in wound healing for deep second degree burn wound. Methods:Sixty Sprague-Dawley rats were randomly di-vidied into six groups(ten rats in each group): the control group (saline), the positive control group (asiaticoside group), Shengji Huayu Fang group respectively with petroleum ether, chloroform, ethyl acetate and n-butanol as the extraction solvent. The extracts of Shengji Huayu Fang with different solvents were applied in the rats with deep second degree burn wound, and the wound healing was e-valuated by the healing rate judged by naked eyes and computer image analysis, DNA cell cycle analysis using a flow cytometry, patho-logical reports and the degree of re-epithelialization studied by the other methods. Results:The mean healing time of the chloroform ex-tracts group [(15. 67 ± 1. 12)d] was much shorter than that of the control group [(22. 87 ± 1. 01)d, P<0. 01]. The hydroxyproline content and the percentage of S-phase cells in wound tissue in the chloroform extracts group was obviously higher than those in the con-trol group (P<0. 01). Conclusion:The present study indicates that topical application of chloroform extracts of Shengji Huayu Fang is beneficial to burn wound healing, and the chloroform extracts of Shengji Huayu Fang is the main bioactive fraction.

Background Researches determined that the pathogenesis of retinal vein occlusion (RVO) is associated with primary open angle glaucoma (POAG) in Caucasian population.However,the relationship between RVO and POAG in Asian population is unclear.Objective This study was to survey the percentage of POAG in RVO patients in China.Methods A prospective cross-sectional observational study based on hospital was performed.Three hundred and seventy five patients with newly diagnosed RVO by fluorescein fundus angiography (FFA) were consecutively enrolled in Peking University Third Hospital from October 2011 to May 2013,and gonioscopy was carried out in all the patients.Glaucoma was diagnosed according to the criteria of the International Society of Geographical and Epidemiological Ophthalmology (ISGEO).RVO was classified into central retinal vein occlusion (CRVO),hemicentral retinal vein occlusion (HRVO) and branch retinal vein occlusion (BRVO) based on fundus photograph and FFA,or classified into arteriovenous crossing RVO (AV-RVO),optic cup RVO (OC-RVO),optic nerve RVO without optical nerve head swelling (NONHS-RVO) and RVO with optical nerve head swelling (ONHS-RVO) based on the sites of venous occlusion.The percentages of POAG in different types of RVO were calculated.This study was approved by Ethic Committee of Peking University Third Hospital,and written informed consent was obtained from each patient before entering study cohort.Results Three hundred and seventeen RVO patients finished screening of glaucoma,with the response rate 84.5％.The percentage of POAG is 8.2％ in RVO patients,including 7.1％ in the CRVO patients,23.5％ in HRVO patients and 6.2％ in BRVO patients.The percentage of POAG was significantly higher in OC-RVO patients (27.9％) and NONHS-RVO patients (13.2％) than that in AV-RVO patients (4.7％) and ONHS-RVO patients (1.3％) (all at P＜0.05).Conclusions The overall percentage of POAG in RVO patients in China is 3-4 times higher than general population.Higher percentage of POAG is found in OC-RVO patients and NONHS-RVO patients,suggesting that pathogenesis of RVO is probably associated with the glaucomatous anatomic changes of optical nerve head.

Objective To establish a sensitive and specific liquid chromatography method for the determination of loganin and morroniside in rat serum containing Liuwei Dihuang Formula(LDF).Methods Loganin and morroniside were extracted from the rat serum using SPE column,then separated on a C_(18)column.A HPLC method for determining serum concentration of mor- roniside and loganin in rats before and after administration LDF was established.Results A good linear calibration curve of lo- ganin and morroniside was obtained.The recovery of the method was in the range of 95 %～105 %.The extracted recovery was more than 75 % ,and within-day and intra-day precisions were less than 12 %.Conclusion This method is sensitive, simple and rapid for monitoring of drug level in the study on pharmacokinetics and different combination of LDF.

Objective To investigate the role and mechanism of RSPO1 in osteoblasts differentiation.Methods The xCELLigence system was used to study the toxicity and role of RSPO1 on the C2C12 cells proliferation.Alkaline phosphatase (ALP) activity was measured by using a phosphatase detection kit.The expression of osteoprotegerin (OPG) was determined using enzyme-linked immunosorbent assay (ELISA).Wnt/β-catenin signaling was evaluated using the TOPflash T cell factor (TCF) luciferase reporter assay.Western blotting assay was performed to confirm the accumulation of β-catenin protein.T test was used for statistical analysis.Results RSPO1 had no effect on the C2C12 cells proliferation,and it produced no toxicity to C2C12 cells.RSPO1 alone resulted in a slight increase in the activity of ALP (2.85±0.08 vs 1.74±0.21,t=3.014,P＜0.05) and the expression of OPG (1.29±0.13 vs 1.00±0.21,t=3.348,P＜0.05),whereas the combination of RSPO1 and Wnt3A significantly amplified ALP activity (81.37±5.08 vs 1.74±0.21,t=31.31,P＜0.01) and OPG protein expression (5.26±0.60 vs 1.00±0.21,t=6.99,P＜0.01).RSPO1 synergized with Wnt3A to activate TCF activity and induce accumulation of β-catenin (3.28±0.18 vs 1.00±0.21,t=10.94,P＜0.05).However,RSPO1 alone had no effect on the TCF activity and β-catenin accumulation (1.25±0.08 vs 1.00±0.21,t=2.225,P＞0.05).Conclusion Our study has revealed that RSPO1 synergized with Wnt3A in activating Wnt/β-catenin signaling pathway to induce osteoblasts differentiation,which demonstrate the therapeutic potential of RSPO1 for RA.
