Background and purpose:Both nature killer cells(NK)and cytoxic T lymphocytes in the body tissues of human are the dominant components of cellular immunity,This study was done to explore the degree of infiltration of NK/T in lung squamous cell carcinoma and its relation to patient survival and prognosis.Methods: CCD8 as the markers cytoxic T lymphocyte(CTL)and CD56 as the markers natural killer(NK)were stained immunohistochemically to detect the distribution and infiltration in the lung squamous cell carcinoma specimens. Results:In 39 of 68 lung neoplasm,whose CTL infiltration was zero or mild,the five-year survival rate was 18%, while in 29 with marked CTL infiltration,the five-year survival rate was 42%.In 46 of 68 lung neoplasm,whose NK infiltration was zero or mild,the five-year survival rate was 14%,while in 22 with marked NK infiltration,the five-year survival rate was 45%.In 48 of 68 lung neoplasm,both the NK and T cells were zero or mild,the five-year survival rate was 33%,while in 20 with marked NK and T cell infiltration,the five-year survival rate was 54%.The five-year survival difference among the patients with NK,T infiltration either marked or zero/mild infiltration were significant(x~2=18.62, P=0.00).Conclusions:The degree of NK and T infiltration is positively correlated with the prognosis and survival time of lung squamous cell carcinoma patients.

OBJECTIVETo study the medium and long term effects of perfusion of bone marrow stromal stem cells through optional artery for the treatment of non-traumatic femoral head avascular necrosis.

METHODSFrom January 2000 to December 2004,62 cases(78 hips) with non-traumatic femoral head necrosis accepted optional artery marrow stromal stem cells infusion treatment and had complete follow-up data, including 43 hips of 35 males and 35 hips of 27 females with an average age of 36.3 years old (22 to 54). According to preoperative imaging data, 16 hips were ARCO I stage, 52 hips were II stage, 10 hips were III a stage. Harris score was 64.94 +/- 8.12 preoperatively. Postoperative Harris score at the last follow-up, imaging changes,DSA vascular changes were analysis.

RESULTSThe patients were followed up for 9 to 13 years (means 11 years). By the end of the follow-up, a total of 18 hips got artificial joint replacement, 10 hips of preoperative ARCO I, II period got artificial hip joint replacement, 8 hips of IIIa period got hip artificial joint replacement. Harris score was 71.21 +/- 0.19 at the end of the follow-up, it was obviously enhanced compared with preoperative. DSA showed blood vessels of supply the femoral head increased thickening.

CONCLUSIONPerfusion of bone marrow stromal stem cells through optional artery can effective treat non-traumatic femoral head necrosis of ARCO I, II period, it can make the femoral circumflex artery and its branches increased thickening.

Objective : To estimate the risk threshold of route index（RI）and mosq-ovitrap index（MOI）based on Breteau index（BI）,as supplements for dengue fever risk monitoring in specific habitats. Methods : Two towns and two streets were selected from nine towns（streets）in Jiashan County,and then one village（community）was selected from each of them as a Aedes albopictus monitoring site. The BI,RI and MOI were employed at the same time and area from April to October in the year 2018. Linear regression models were built with RI,MOI and BI to calculate the dengue risk threshold of RI and MOI according to BI. Results : The linear regression model of BI（X）and RI（Y）was Y=0.145+0.662X（P<0.05）,of BI（X）and MOI（Y）was Y=3.423+0.524X（P<0.05）. If BI=5（having risk of transmission of dengue fever）,then RI=3.455（95%CI：1.717-5.198）,MOI=6.043（95%CI：-0.327-12.417）. If BI=10（having risk of outbreak）,then RI=6.765（95%CI：5.018-8.518）,MOI=8.663（95%CI：2.260-15.071）. If BI=20（having risk of epidemic）,then RI=13.385（95%CI：11.326-15.453）,MOI=13.903（95%CI：6.352-21.461）. Conclusion The dengue fever risk threshold of RI estimated by BI had a narrow 95%CI and could be applied for dengue fever risk assessment,while the risk threshold of MOI had a wide 95%CI and the application value needed further study.
