Objective To understand the status and features of nursing care adverse events and to offer scientific basis for improving patient safety management of nursing at high altitude area. Methods Data such as categories, causes, time distribution and other factors of nursing care adverse events were collected from January 2013 to August 2014 in the People′s Hospital of Tibet Autonomous Region were analyzed. Results Over the study period, 50 adverse events were recorded and the most common types were tube emersion(26%,13/50), pressure sores(14%,7/50) and scald(12%,6/50) respectively. The proportions of different severity of adverse events were hidden events (48%,24/50), events without bad consequence(36%,18/50), adverse events(14%,7/50) and warning events(2%,1/50) respectively. The ineffective communication, inadequate assessment, and not abiding by the rules accounted for 70%(35/50) of the causes of adverse events. 7:00-10:59 and 19:00-22:59 period was the high incidence of adverse events, respectively accounted for 32%(16/50) and 26%(13/50). Conclusions The management of nursing adverse events at high altitude area need to consider the geographical characteristics,besides, to guarantee the implementation of the system,reduce the bed / nurse ratio, improve the comprehensive quality of nurses and other measures can be taken to reduce the occurrence of adverse events.

Abstract?AIM: To investigate the effect of epigallocatechin-3-gallate ( EGCG ) against oxidative stress induced by high glucose in human lens epithelium ( HLE) cells.? METHODS: The HLE cell oxidative damage model induced by high concentration glucose was established, and was intervented with different concentrations of EGCG. Cell viability was determined by MTT assay, cell morphology was investigated by convert microscope, cells apoptosis was assayed by flow cytometry with Hoechst-PI staining. Moreover, the levels of super oxide dismutase ( SOD) , glutathione peroxidase ( GSH-Px) and malondialdehyde ( MDA) in supernatant were also tested after different treatment either with high concentration glucose or with different concentrations of EGCG.?RESULTS: MTT results showed that HLE cells activity increased to 50. 33%± 3. 52% and 63. 33%± 4. 63% after treated with 10 μmol/L and 100 μmol/L EGCG respectively, the difference was statistically significant compared with oxidative injury group(32. 67%±3. 10%)(P<0. 05 ); HLE cells maintained better morphology intervented with EGCG under high glucose conditions, the number of apoptotic cells reduced, SOD and GSH-Px level within HLE cells increased and MDA levels decreased.?CONCLUSION:EGCG plays its strong antioxidant effect by increasing SOD, GSH-Px content and decreasing MDA content in cells, therefore provides a reliable experimental basis for the search for effective prevention and treatment of cataract drug.

Objectives: To find out the demands and status in quo of the development of specialty nursing and to provide positive suggestions for the further development of specialty nursing in Tibet. Methods: Self-designed questionnaire was adopted to investigate 16 different level hospitals across Tibet. Results: Among the 16 hospitals in which there were altogether 1677 nursing staff and only 11 hospitals had cultivated specialty nurses with a number of 123 in total. The rate of specialty nurses allocated was 7.2%. 9 hospitals expressed the need to develop specialty nurses in nearly future and the number of specialty nurses needed was 577. Conclusion Tibet should step up the development of specialty nursing, establish and perfect the training method and management system about specialty nurses as soon as possible.

Objective To study the relationship between traditional Chinese medicine (TCM)syndrome differentiation of multiple myeloma(MM)and laboratory indexes of MM,thus to supply evidence for the syndrome differentiation of MM. Methods A total of 59 MM patients were enrolled in the study. TCM syndrome differentiation was performed. And we also collected the laboratory indexes of serum protein electrophoresis (SPE),immunofixation electrophoresis (IFE),blood urea nitrogen (BUN),creatinine (CREA),serum beta 2 microglobulin,serum calcium(Ca),hemoglobin(Hb),Bence Jones protein,flow cytometric-immunophenotyping(FCM) and bone marrow cytology. The differences of the laboratory indexes in various syndrome types of MM were analyzed. Results No significant differences were found in myeloma cell morphology, M protein content, IFE typing results, Bence Jones protein positive rate and the concentration of Ca of various syndrome types of MM (P >0.05). However,the concentrations of BUN,CREA,serum beta 2 microsglobulin,Hb,and the positive rates of CD19- and CD56+ were significantly different in various syndrome types of MM (P < 0.05 or P < 0.01). Moreover,Hb,BUN,CREA,and serum beta 2 microspheres were significantly correlated with each other(P<0.05 or P < 0.01). Conclusion Hb, BUN, CREA, blood beta 2 microglobulin and FCM detection can be sued for the auxiliary diagnosis of syndrome types of MM, and for preliminary demonstration of illness severity and prognosis. The results will provide the basis for the treatment of MM with traditional Chinese medicine and western medicine.

Objective:To observe the clinical efficacy of balance-impact tuina therapy for lumbar intervertebral disc herniation (LIDH).Methods:A total of 118 eligible LIDH patients were randomized into an observation group and a control group by the random number table method,with 59 cases in each group.The observation group was intervened by balance-impact tuina therapy,while the control group was intervened by conventional tuina therapy,both for consecutive two weeks.The scores of visual analog scale (VAS),Oswestry disability index (ODI),quality of life questionnaire-core 30 (QOL-C30) were observed before and after treatment;the relapse rate was estimated at the sixth month and twelfth month following the treatment.The data were statistically analyzed.Results:After intervention,the total effective rate was 96.6％ in the observation group versus 91.5％ in the control group,and the between-group difference was statistically significant (P＜0.05).The VAS and ODI scores declined significantly after treatment in both groups (all P＜0.05),and the observation group was markedly lower than the control group (P＜0.05,P＜0.01).The QOL-C30 score increased significantly after treatment in both groups (both P＜0.05),and the observation group was markedly higher than the control group (P＜0.05).The relapse rates at the post-treatment sixth month and twelfth month in the observation group were lower than those in the control group (P＜0.05,P＜0.01).Conclusion:Compared with the conventional tuina therapy,the balance-impact tuina therapy shows advantage in lessening pain,improving the function and enhancing the quality of life in the treatment of LIDH,and it has a lower relapse rate.Thus,this therapy is worth promoting in clinic.

BACKGROUNDKeratinocyte serum-free medium (K-SFM) is a defined medium used to support the growth of primary keratinocytes and embryonic stem cell. The aim of this research was to optimize enrichment of breast cancer stem cells (CSCs) using K-SFM.

METHODSA K-SFM was used to enrich CSCs from two breast cancer cell lines and a primary culture of breast cancer. RPMI-1640 supplemented with 10% fetal calf serum (FCS) was used as a control. CSCs were identified with flow cytometry using CD44(+)/CD24(-) as molecular markers. The expression of a variety of CSC markers (Oct-4, ABCG2, Nanog, N-cadherin, and E-cadherin) was analyzed with real-time PCR.

RESULTSMuch higher percentage of CSCs was achieved with K-SFM: 17.3% for MCF-7 cells, 17.4% for SKBR-3, and 20.0% for primary breast cancer culture. Less than 1% CSC was achieved using RPMI-1640 supplemented with 10% FCS. In comparison to the CSCs obtained with RPMI-1640, CSCs in the K-SFM expressed higher levels of Oct-4, ABCG2, Nanog and N-cadherin, and lower level of E-cadherin.

CONCLUSIONK-SFM is an optimal culture medium to maintain and to enrich breast CSCs.
