Objective To observe the effects of health promotion on tumor recurrence,quality of life and self feeling evaluation of patients with superficial bladder carcinoma.Methods 104 patients with superficial bladder carcinoma treated in our hospital from March 2002 to March 2005 were divided to two groups randomly.The patients in one group were treated by bladder irrigation with Bacille Calmette Guerin (BCG)simply,and those in the other group were treated by bladder irrigation and health promotion.Tumor recurrence,quality of life and self feeling evaluation between the two groups were compared.Results All patients were foUowed up for 7.3-36.0 months(mean 28.5 months).17 patients(15/51)in the simple BCG irrigation group had tumor recurrence in 0-12 months(2 patients),13-24 months(6)and 25- 36months(9)respectively.The recurrence rate in the first year was 3.9%.in the second year 11.8% and in the third year 17.6%.Eleven(11/53)patients had in the BCG irrigation and health promotion group.in 0-12 months(2),13-24 months(7),and 25-36 months(2)respectively.The recurrence rate in the first year was 3.8%.in the second year 13.2%.and in the third year 3.8%.There were no significant differences in the recurrence rates of the first and second year between the two groups(P>0.05).but there was significant difieFence in the recurrence rate of the third year between the two group(Y2=5.29,P< 0.05).There were no significant difierences in self feeling SCL-90 evaluation and quality evaluation of life after the first discharging between the two groups(P>0.05).After 3-year follow up,the life quality of the patients in the BCG irrigation and health promotion group was improved obviously compared with the simple BCG group(X2=6.47,P<0.05),and the bad negative emotion was diminished obviously compared with the simple BCG group(P<0.05).Conclusion Health promotion after operation on the patients with superficial bladder carcinoma can decrease the long-term tumor recurrence rate obviously,and improve the quality of life and self feeling significantly.

To support the ongoing health reform in China,Chongqing municipal government made the decision in 2008 "Building Healthy Chongqing" ,and pinpointed for the first time regional development as a key goal.In line with this situation,the hospital proposed such hypothesis changes as from "disease hypothesis to "health hypothesis",from "illness oriented" to "capability oriented",and from "shaping development" to "adaptive development",as well as from one-sided efforts of medical staff to minimize casualty to joint efforts with patients to safeguard life and health.Focusing on these four strategic shifts,the hospital works in developing its "technical attraction,service capacity,innovation capacity,and emergency assurance capability,and management soft power",aiming at building a sustainable hospital in its development.

Objective To determine the taxonomic position of medically important gamasid mites and to compare numerical taxonomy with the traditional systematics in the classification of gamasid mites. Methods Based on hierarchical cluster analysis, numerical taxonomy was applied to study fifty-seven species of medically important gamasid mites. Results The results of cluster analysis based on squared euclidean distance showed that Hirstionyssus Fonseca and Echinonyssus Hirst should be separated from Laelapidae Berlese and formed an independent family. The taxonomic position of the remaining species remains the same as those in the traditional systematics. Conclusion Numerical taxonomy can objectively reflect the taxonomic position of the medically important gamasid mites. The result of classification by numerical taxonomy is consistent with traditional systematics for gamasid mites.

This paper studied the usage and impact of the theory in hospital development.Based on such,special manifestations behind the marginal diminishing effect are taken into consideration to grasp particular demands and requirements of health,and to look for a positive role and a progressive increase of the marginal utility.Furthermore,the explorations in hospitals,such as technical innovations,structure optimizations and management breakthroughs,as well as the experimental and practical construction of micro-economic administrative mechanism in clinical departments were discussed in the text.It has been demonstrated in practice that the practice has a significant effect on the prevention of marginal diminishing utility and an essential reference on hospital transformational development.

Objective To identify the significance of expression and phosphorylation of protein kinase R(PKR) and nuclear factor NF-κB p65 in cervical lesions, and the effect of high-risk human papilloma virus(hsHPV) on expression and phosphorylation of R(PKR) and NF-κB p65. Methods A total of 67 patients with cervical cancer, 149 patients with cervi-cal intraepithelial neoplasia (CINⅠ-Ⅲ) and 15 normal control were included in this study. The expression levels of PKR, phosphorylated PKR (p-PKR), NF-κB p65 and phosphorylated NF-κB p65 (p-NF-κB p65) were detected by immunohisto-chemical SP method in three groups. Results The positive expression rates of PKR and p-PKR in cytoplasm were signifi-cantly lower in hsHPV positive group than those in hsHPV negative group (27.2% and 11.0% vs 41.1% and 21.1%,χ2 =4.858 and 4.371,P＜0.05). The positive expression rates of NF-κB p65 and p-NF-κB p65 in cytoplasm and nucleus were significantly higher in hsHPV positive group than those in hsHPV negative group (46.3%, 25.7%, 22.8% and 12.5% vs 32.6%, 14.7%, 11.6%and 4.2%,χ2=4.345,4.048,4.729 and 4.650 respectively,P＜0.05). The positive expression rates of PKR in kytoplasm and karyon were significantly lower in NF-κB p65 (+) group than those in NF-κB p65 (-) group (25.5%vs 38.0%and 20.4%vs 36.3%,χ2=3.898 and 4.396 respectively, P＜0.05). The positive expression rate of PKR in kyto-plasm was significantly lower in p-NF-κB p65 (+) group than those in p-NF-κB p65 (-) group (19.0%vs 36.0%,χ2=4.462, P＜0.05). Conclusion hsHPV may inhibit the expression and phosphorylation of PKR but promote the expression and phosphorylation of NF-κB p65. The expression and phosphorylation of NF-κB p65 may inhibit the expression of PKR. Regu-lating effects of three may be associated with the generation and progression of cervical cancer.
