Objective To analyze the quality of life(QOL)of patients with acute stroke,and to explore the effects of early specialized rehabilitation on their QOL.Methods Seventy patients with acute stroke were randomly divided into a rehabilitation group(n =35)and a control group(n =35).The rehabilitation group received specialized rehabilitation treatment while the control group received self-rehabilitation.QOL we evaluated with the short form-36(SF-36)instrument before and after.Results Before treatment,QOL scores in the both groups were much lower than the norms for healthy people.The differences on each dimension of the SF-36 were not statistically significant between the two groups.The SF-36 scores of both groups improved during the experiment,but after 1 month and 6 months the improvement on each SF-36 dimension was significantly better in the rehabilitation group than in the control group.Conclusions The QOL of patients with acute stroke is significantly impaired,but specialized rehabilitation treatment is effective in improving it.

Objective To explore the correlation between serum cytokines and the depression degree in the patients with colorec-tal cancer.Methods 9 6 cases of colorectal cancer were selected and divided into 2 groups according to the patients health question-naire(PHQ-9):the depression group (52 cases)and the non-depression group (44 cases),and 40 healthy cases were recruited as the control.Serum interleukin-2 (IL-2),soluble interleukin-2 receptor (SIL-2R)and tumor necrosis factor-α(TNF-α)were detected by enzyme-linked immunosorbent assay(ELSIA).The detection results were compared among various groups.And the correlation be-tween the expression of various cytokines and the depression degree was analyzed by the Pearson′s correlation coefficient.Results The levels of IL-2,SIL-2R and TNF-αhad statistical differences among 3 groups (P<0.05);no statistical difference in the TNF-αexpression was noted between the depression and the non-depression groups (P>0.05),but which in these two groups was higher than that in healthy group (P<0.05);the IL-2 level in the depression group was significantly lower than that in the non-depression group(P<0.05);the SIL-2 R level in the depression group was obviously higher than that in the non-depression group (P<0.05), moreover,which in these two groups was higher than that in the healthy group (P<0.05).By correlation analysis,the depression degree in the patients with colorectal cancer was negatively correlated with the IL-2 level (r=-0.259,P<0.05)and positively correlated with the SIL-2R level(r=0.412,P<0.05).Conclusion The levels of IL-2 and SIL-2R have certain correlation with the depression degree in the patients with colorectal cancer,it is speculated that the above cytokines may play a mediating role in the pathogenesis process of depression in the colorectal cancer patients.

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.

Inducible costimulatory molecule(ICOS)is a member of the CD28 family,which can be expressed on the tumor tissues and immune cells in the tumor microenvironment. ICOS enhances its anti-tumor activity through participating in CD4 + T and CD8 + T cell immune response and enhancing the secretion of cyto-kines on the activated T cells and NK cells. While the curative effect of cytotoxic T lymphocyte-associated anti-gen-4(CTLA-4)monoclonal antibody is relevant with CD4 + T cells expressing ICOS,which suggesting ICOS may become a novel anti-tumor therapeutic target in the future.

BACKGROUND: Alienation is derived from dissimilation in philosophy.It is practically defined as the subjective state of individuals who develop negative feelings such as social isolation, uncontrollable and meaningless sense, oppression, and self-alienation because they are alien to others, the.society, nature and themselves, and even feel controlled.OBJECTIVE: To investigate alienation from psychological perspective,aiming to construct and verify the theoretical hypothesis of alienation,thereby working out alienation scale for adolescent students.DESIGN: Cross-sectional investigation.SETTING:National Key Research Center of Basic Psychology and National Key Liberal Arts of Southwest Normal University.PARTICIPANTS: The investigation was carried out from March to June 2000. The method of cohort stratified random sampling was adopted and the questionnaire was administered to adolescent students in Chongqing City and Lanzhou City. Inclusion criteria: volunteer students of grade one in junior high school to grade four in colleges. Exclusion criteria: Those who had incomplete data or had differences of more than 6 points in the total scores for three matched lie-testing questions in the questionnaire. A total of 1502 pieces of questionnaire were collected (including 1 066 questionnaires used for exploratory factor analysis and 436 questionnaires for verifying factor analysis); the age of the students covered the whole range of adolescence, and the boy-to-girl ratio in each grade was matched.METHODS:We combined literature analysis, investigation research and interview. The details are as follows: First, theoretical hypothesis was put forward based on literature analysis; then related variances were collected through interviews and open questionnaires, which were compared with the items in scales used home and abroad at present so as to work out predicting questions for adolescence alienation questionnaire. Finally, 52 items were screened out and used to construct the preliminary questionnaire. The formal alienation scale was made after standardized designation of behavioral variances, and verified for alienation analysis in adolescent students.MAIN OUTCOME MEASURES: Behavioral apparent variances were collected based on interviews and open questionnaires, and used as psychological potential variances after statistical processing.RESULTS:Data of 1502 pieces of questionnaire were analyzed.① The correlation coefficient of each item in the scale was over 0.35. ② The correlation coefficient of each item with the dimension was over 0.30, with statistical significance(P ＜ 0.01). ③ The reliability coefficient of each item was over 0.39 with great significance(P ＜ 0.01). ④ Alienation was displayed in three dimensions: social alienation, interpersonal alienation and surrounding alienation, which were associated with the correspondingdimensions of related scales (P ＜ 0.05-0.01). ⑤Alienation could be divided into 9 levels: sense of meaninglessness, sense of self alienation, isolation, nature alienation, parent alienation, environmental alienation, sense of uncontrollability and social alienation. Parameters that accorded with the theoretical hypothesis and used for verifying analysis were proved rational.Based on the analysis of the 9 first-rank factors, second-rank structural model of 3 unrelated factors were obtained using main component analysis and the maximum variance cross rotation with the optimal coefficients of simulated parameters of: X2/df=4.87;GFI=0.94;A GFI=0.90;RMR=0.0S;NFI=0.93;NNFI=0.92;CFI=0.95;IFI=0.95.CONCLUSION: Alienation scale has been proved to be reliable and valid. It can be used to assess alienation in adolescent students and has potential value of application in healthy psychological development and psychological education.

Gemcitabine is important pyrimidine antimetabolites drug. Ribonucleotide reductase is oneof its targets whose overexpression has been observed in several gemcitabine- resistant cell lines. Meanwhile,the NSCLC patients with high RRM1 expression levels have a relatively poor survival when treated with gem-citabine. To this day, the relationship between RRM1 expression levels in peripheral blood mononuclear cellsand gemcitabine is still uncertain and it deserves further research.

Microcirculation disturbance and ischemia of the pancreas are important pathophysiological changes in the onset of acute pancrea-titis,and organ hypoperfusion is a risk factor for poor prognosis.During the first 12 to 24 hours after admission,fluid resuscitation is the most important medical treatment for the early stage of acute pancreatitis,and timely and rational fluid infusion helps to improve prognosis. However,there lacks high -quality clinical evidence for type of fluid,infusion speed,and monitoring methods,and more randomized con-trolled trials are needed.
