Objective:To study the environment suitability of multi-parameter patient monitor. Methods: Choosing six different types of multi-parameter patient monitor from different manufactures, we tested six main parameters of the multi-parameter patient monitor when they had gone through the environmental tests, and the test limits come from field environment. Results:Each of the samples was not up to the standards. Conclusion:At present a clear most of the multi-parameter patient monitor in the market are designed and produced for using indoors, which are not suitable for using in field environment. We need to enhance the protection of the multi-parameter patient monitor against field environment, and improve the environment suitability.

Bio-safety problem was emerging as more and more important with the development of biotechnology,and many governments concerned about it.We analyzed the different category of biotechnology related with bio-safety problem,and found out its main influencing factors and safety results.In the course of research and development of biotechnology,misuse,abuse and non-moral use are three main human factors.We concluded that the situation of bio-threat would be more diverse,and also the misuse chance would increase.It will be benefited that public health manager make regulations and legislature with full dimension of bio-safety assessment of different biotechnologies.

Objective To evaluate the influence of tirofiban to percutaneous coronary intervention.Methods 66 elderly patients with coronary artery disease were treated,they were divided into the study group of 33 cases and the control group of 33 cases.The control group was treated with simple percutaneous coronary intervention treatment, the study group was treated with percutaneous coronary intervention combined with tirofiban.The changes of LVEF, cTnT,and TIMI,symptoms in the treatmeat and the symptoms after 2 years were observed and compared.Results After treatment,the patients'platelet count was to the basic line,the difference was not statistically significant(t =0.353 3,P >0.05).The cTnT,LVEF levels of the study group were significantly better than the control group,the differences were statistically significant(t =5.138 1,8.658 1,all P <0.05).After treatment,the incidence rate of TIM in both two groups were improved compared with before treatment.After treatment,the incidence rate of TIMI 3 of the study group(93.9%) was significantly higher than the control group(69.7%),the difference was statistically significant(χ2 =6.518 5,P <0.05).After treatment,the remission rate of angina of the study group(87.9%) was significantly higher than the control group(60.6%),the difference was statistically significant (χ2 =6.417 8,P <0.05).After 2 years of follow -up , the remission rate of angina and recurrent angina in the study group were significantly better than the control group,the differences were statistically significant (χ2 =5.076 9,3.995 2,all P <0.05).Conclusion The efficacy of percutaneous coronary intervention combined with tirofiban is significant,the prognosis is good,has higher remission,it is suitable for long -term clinical application.

Objective To investigate the correlation of platelets-to-lymphocyte ratio (PLR) with neutrophil-to-lymphocyte ratio (NLR) from pretreatment in the Xinjiang Uygur patients with nasopharyngeal carcinoma.Methods In this retrospective analysis,96 cases of nasopharyngeal carcinoma patients with pathologically diagnosis were collected.Receiver operating characteristic (ROC) curve analysis suggested that optimum PLR and NLR cut-off point for nasopharyngeal carcinoma.The patients were divided into high-PLR and low-PLR groups,high-NLR and low-NLR groups,respectively.The survival rate was calculated with Kaplan-Meier method.The Log rank statistics was used to test differences between groups.The prognostic factors that may affect patients with nasopharyngeal carcinoma in Uighur population of Xinjiang were analyzed by COX proportional hazards models.Results For high-PLR and low-PLR groups,5-year overall survival,and progression-free survival were 46.6％ and 79.3％,49.8％ and 82.7％,respectively;the difference was statistically significant (all P ＜ 0.01).For high-NLR and low-NLR groups,5-year overall survival rate,and progression-free survival rate were 41.3％ and 41.3％,50.8％ and 82.5％,respectively;the difference was statistically significant (all P ＜ 0.01).Univariate analysis showed that N stage,clinical stage,NLR,and PLR had significantly impact on overall survival and progression-free survival (all P ＜ 0.05);multivariate analysis showed that PLR and clinical stage had statistical significance in Uighur patients with nasopharyngeal carcinoma for progression-free survival and overall survival (all P ＜ 0.05).Conclusions PLR may be independent factor that influences the prognosis of patients with nasopharyngeal carcinoma in Uighur population of Xinjiang.

Objective To observe the protective effect of dexamethasone, the inhibitor of nuclear factor-Kappa B, on the ischemia-perfusion injury of rat lung during the period of lung preservation. Methods Twenty-four rats were randomly divided into two groups: the control group and the trial group. The harvested lung blocks were flushed with and stored in the low-potassium-dextran (LPD) solution in control group, but in the trail group LPD containing dexamethasone solution was used. The lungs were stored at 4 ℃ for 16 h in both groups. The isolated rat lung reperfusion models were established and the donor lungs were perfused for 1 h. PaO_2 and PawP were measured at every 15 min intervals during reperfusion. After reperfusion, the lung tissue wet-to-dry (W/D) ratio and myeloperoxidase (MPO) activity were obtained. The protein and mRNA expression of intercellular adhesion molecule-1 (ICAM-1), nuclear factor-Kappa B (NF-?B) was also detected by using immunohistochemistry and semi-quantitative RT-PCR at the end of reperfusion. Results The levels of decreased PaO_2 and increased PawP in trail group were lower than in control group at the every interval time in the samples obtained 15 min after reperfusion (P

Objective: To investigate the effects of insulin on the DNA synthesis and cell cycle distribution of human periodontal ligament cells (PDLs). Methods:PDLs were treated with insulin at the doses (U/L) of 0.01～1 000 for 72 h,DNA synthesis of the cells was measured by 3H-TdR incorporation and cell cycle distribution was studied by flow cytometer. Results : Insulin at 1 U/L to 1 000 U/L showed a significant concentration dependent stimulation of 3H thymidine uptake, and the effect of insulin at 100 ～ 1 000 U/L were not statistically different from that at 10 U/L. The percentage of PDL cells in G1 phase during exponential growth was decreased by insulin, while that in S phase and (G2+M) was increased in experimental group. Conclusion: Insulin increases DNA synthesis of PDL cells ,and stimulates the transformation of cells from G1 to S phase.

Objective To understand the cogniton,attitude and behavior of the psychological counseling in college students,and the results should be helpful to mental health promotion programs.Methods 585 college students were recruited by a cluster sampling.A self-designed questionnaire about the psychological consultation was finished by the subjects.All the data were entered a database with Epi Data V3.1 software.Statistical analysis of the data was done on the SPSS software (V13.0).Chi-square test was used to compare the constituent ratio difference among different groups.Results 64.10% students considered the function of counseling was to help person better understand themselves;63.72% of students agreed with that it is very necessary to carry out psychological counseling in college.When they encountered some confusion which beyond their ability to solve,they will at first resort to their friends,parents other than counseling Center in campus.32.58% of students didn’t know the counseling center in their college.Only 8.38% of students ever went to the counseling center.Conclusions Although the majority of students hold positive attitudes and cognition about psychological counseling.However,their behavior was negative.It is contradictory between their cognition and behavior.It is very necessary to explore the deeper reasons and carry out some targeted health education in college students.
