Methods According to the different drugs,nursing interventions will be January 2015 to March 2017 in third affiliated hospital of Tianjin medical university for surgical treatment of gynecological cancer patients 80 cases groups:control group with routine nursing intervention observation group with mannitol, psychological nursing and compound polyethylene glycol electrolyte with intervention;observation of two groups of patients improve psychological status and intestinal cleaning and the incidence of adverse reactions,the strict record related data and make comparative analysis. Results The psychological nursing and compound polyethylene glycol electrolyte powder(observation group)intervention in patients with gynecologic tumor significantly,the psychological state of patients with improvement than the control group,the bowel cleaning is better than the control group,the difference was statistically significant(P<0.05);two patients with adverse reaction rate comparison,the difference was not statistically significant. Conclusion The preparation of intestinal tract tumor patients before gynecologic selection of psychological nursing and intervention effect of polyethylene glycol electrolyte powder can significantly improve the psychological state,full bowel cleansing patients with high effective rate,and will not increase the adverse reactions,and is worthy of clinical application.

In this study,amount to 23 strains of marine fungi had been isolated from anemones which inhabited on the rocks of the intertidal zone of Qingdao sea area,and the bioactivity of antimicroorganism had been determined.There are 15 strains of fungi from Anthopleura Qingdaoenisis Pei belong to 4 different genus of Fungi Imperfecti,and 8 strains of fungi from A.Midori fall respectively into 6 genus of fungi inperfecti.Among the 23 strains of fungi isolated,there are 3 strains that can inhibit the pathomycete of plants.

This paper is to observe the effect of tetrahydrobiopterin (BH 4) on lipid peroxidation in hypercholesterol rabbits.A total of 24 rabbits were randomly divided into 4 groups:normal diet(group A),BH 4 plus hypercholesterol diet(group B),VitE plus hypercholesterol diet(group C) and hypercholesterol diet(group D). After 30 d,serum total cholesterol(TC), superoxide dismutase (SOD) and malondialdehyde (MDA) were determined.The amount of TC in group A was lower than that in other groups( P

Purpose To investigate the expression of mTOR in breast cancer, and to observe the effect of CCI-779 on proliferation and apoptosis of MDA-MB-231 cell. Methods Immunohistochemical staining was used to detect the expression of mTOR protein in breast cancer tissue and MDA-MB-231 cell. MTT method was used to show effect of CCI-779 on proliferation of MDA-MB-231 cell. Annex-inV-FITC/PI method was used to show effect of CCI-779 on apoptosis of MDA-MB-231 cell. Results 54.9% in 71 cases of breast cancer tissue could express mTOR protein, the expression was significantly higher than in 32 cases of normal tissue (21.9%), mTOR protein was also detected in MDA-MB-231 cell, CCI-779 could inhibit the proliferation of MDA-MB-231 cell, and show a dose-and time-dependent, but CCI-779 could not induce apoptosis of MDA-MB-231 with AnnexinV-FITC/PI assay. Conclusion mTOR is closely related to the formation of breast cancer, CCI-779 has strong activity against MDA-MB-231 cell, it has prospect for treatment of breast cancer in the future.

Proteins arc the major molecules performing life activities, and their spatial and temporal expression profiles in organisms are very important for understanding their accurate functions. Phospholipid hydroperoxide glutathione pcroxidase (PHGPx) is a unique antioxidant enzyme that directly reduces lipid hydroperoxides in biomembranes and plays a vital role in defense against mernhrane peroxidation damage. The protein expression profiles of rice PHGPx (OsPHGPx) were investigated in different rice tissues and under various stress treatments by using Western blot analysis. The results showed that in mature rice plants, OsPHGPx was mainly distributed in leaves, especially flag leaves, and in rice seedlings, OsPHGPx was detected in shoots and leaves. Moreover, OsPHGPx expression in rice seedlings could be markedly induced by H2O2 and NaCI, but weakly influenced by several plant hormones. Time- and dose-dependent effects were observed in both H2O2 and NaCI treatments, and the strongest induction was observed when rice seedlings were treated with 0.5 mmol/L H2O2 for 12 h or 500 mmol/L NaCI for 24 h. Additionally, dimethylthiourea, a H2O2 trap, inhibited H2O2-enhanced expression of OsPHGPx, but did not impair the enhanced effect of NaCI, implying that NaCl-induced OsPHGPx expression was not mediated by H2O2. These results will contribute greatly to further study the exact physiological function of OsPHGPx in rice.

Objective To evaluate the long term results of coral bone used in anterior cervical interbody fusion. Methods The 180 patients (126 males and 54 females) who had undergone anterior interbody fusion in our hospital were followed up for 6 years. Their long-term imageological data, including changes in interbody height, interbody angle and range of movement, were analyzed and compared. Results In all the cases a solid fusion was achieved between coral reef and vertebra. The fusion was evaluated as successful in all the 180 patients. Conclusion The coral bone spacer provides the same solid fusion as autografting with iliac crest does.

Objective To evaluate the feasibility of detecting peripheral artery disease (PAD) using ankle-brachial index (ABI) determined by an electronic sphygmomanometer in patients with type 2 diabetes mellitus (DM). Method The brachial blood pressure and the ankle blood pressure were measured in each upper limbs and lower limbs by the Doppler ultrasound method and the electronic sphygmomanometer method in fifty-nine DM patients who were selected from Department of Geriatric Endocrinology of General Hospital of PLA. ABI was calculated with the formula of ABI = ankle systolic blood pressure/ brachial systolic blood pressure. The measurement data were expressed as x?s. Then the data of systolic pressure and ABI were analyzed by paired Student's t tests and correlations. The related diagnosis criteria of PAD, such as sensitivity, specificity, positive predictive value, negative predictive value, and the global accuracy were calculated. Furthermore, the correlation of brachial blood pressure as measured by the electronic sphygmomanometer and the mercury column sphygmomanometer was compared. Results There were no significant differences but good correlations between the data of systolic pressures and ABI obtained as measured by two methods. The correlation for systolic pressure was: right upper limbs 0.92, P

Objective To compare the durability and economic value of o-phthalaldehyde(OPA)and glutaraldehyde as endoscope disinfectors in continuous use of cleaning machine.Methods Compare the maximal number of endoseopes which could be disinfected by the two disinfectors at its minimal effective concentration,as well as the corresponding costs.The cost-effectiveness of two disinfectors were evaluated with Revenue-Incremental Cost Analysis.Results The number of endoscopes disinfected by OPA were 1.56 times as compared with glutaraldehyde,and an additional 2.95 yuan could be gained with OPA at the cost of 1 yuan.Conclusion When cleaning machine is full loaded,OPA is more durable than glutaraldehyde,and Can gain more benefit at the same cost.
