Objective To investigate the expression and clinical value of immunohistochemistry in endometrial stromal tumors.Methods Immunohistochemical technique(Envision method)was applied to de- tect the expression of CD_(10),SM-MHC,h-caldesmon,AE1/3,CD_(99),Ki-67,CD_(34),c-kit,ER and PR in 15 cases of endomertrial stromal sarcoma and 3 metastases.The clinical pathological data,including the histological characteristics,histochemical and immunohistochemical staining features,complication,differential diagnosis and prognosis of endometrial stromal tumours were analyzed.Results Among the 18 cases of endometrial stromal tumor,17 cases had shown positive for CD_(10),including 13 cases diffuse positive and 4 muitifocal,7 cases with smooth muscle differentiation,3 cases with epithelial differentiation,7 cases with sex-cord differ- entiation.13 cases of ER and 16 cases of PR were positive expression in endometrial stromal sarcoma.Ki-67 in range 36 %～78 %.Conclusion Endometrial stromal tumour can display multi-differentiation.They show various pathomorphological features,Smooth muscle and sex-coed differentiation,the most common types. CD_(10) can be expressed consistently in endometrial stromal tumors.CD_(10) with h-caldesmon and SM-MHC can be used to make differential diagnosis between the endometrial stromal tumors and cellular leiomy0ma.ER and PR should be routinely estimated and be a prognostic predictor for endometrial stromal sarcoma.

OBJECTIVEThe aim of our study was to investigate the prevalence of target organ damage (TOD) in elderly hypertensive inpatients.

METHODSData of the present retrospective survey were collected and analyzed from the computerized medical records of 17 682 aged 60 years or older inpatients with the diagnosis of essential hypertension (EH) from January 1993 to December 2008 in our hospital. The evidences of hypertensive TOD and associated risk factors with TOD including age, gender, presence of diabetes (DM), body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP), serum lipids were analyzed.

RESULTSThe overall prevalence of stroke, coronary artery disease (CAD), chronic kidney disease (CKD) and aortic dissection (AD) was 32.19%, 27.33%, 10.12% and 0.77%, respectively. Incidence of TOD was 68.03% in male and 31.70% in female patients. CKD stage 3-5 was more prevalent in males than in females (12.75% vs. 5.40%, P < 0.01), while the prevalence of CAD (31.31% vs. 27.96%, P = 0.06), Stroke (28.23% vs. 25.81%, P = 0.08) and AD (0.89% vs.0.74%, P = 0.72) was similar between men and women. One TOD was presented in 23.20% patients and two or more TODs were found in 47.19% patients. Higher age and BMI, longer history and lower control rate of hypertension, severe degree of hypertension and higher level of SBP, pulse pressure, TC, LDL-C, estimated GFR (eGFR) and Hcy were risk factors for TOD. BMI, fasting plasma glucose, incidence of DM, prevalence of stage 1 and 2 hypertension, control rate of hypertension, eGFR and TG levels were all significantly higher while the prevalence of hypertension stage 3 and level of TC and LDL-C were significantly lower in female TOD patients than in male TOD patients (all P < 0.05). In patients without TOD, TG was significantly higher while SBP, fasting plasma glucose and LDL-C were significantly lower and history of hypertension was significantly shorter in female patients than in male patients (all P < 0.05). The prevalence of CAD, stroke and CKD increased with age (P < 0.001).

CONCLUSIONThe prevalence of TOD is high in elderly hypertensive inpatients and higher age and BMI, longer history and lower control rate of hypertension, severe degree of hypertension and higher level of SBP, pulse pressure, TC, LDL-C, eGFR and Hcy are risk factors for TOD.

OBJECTIVETo confirm whether human MHC class I chain-related A (MICA) induces the amplification of V delta 1 gamma delta tumor-infiltrating lymphocytes (TILs) in vitro and to identify the cytotoxicity of MICA-reactive V delta 1 gamma delta TILs towards epithelial tumor cells.

METHODSMICA protein was prokaryoticly expressed and purified by molecular cloning technology. The purified recombined MICA (rMICA) was used to induce V delta 1 gamma delta T cells from tumor tissues in vitro and the cytotoxicity of these V delta 1 gamma delta TILs were tested by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT).

RESULTSThe rMICA was expressed in prokaryocyte with pET30 as a vector. The immobilized rMICA protein could markedly induce the amplification of V delta 1 gamma delta T cells from tumor tissue in vitro. These V delta 1 gamma delta T cells showed strong cytolytic activities towards tumor cell lines expressing MICA.

CONCLUSIONThe MICA-reactive V delta 1 gamma delta T cell may be a candidate for adoptive cellular therapy of tumors.
