Objective To study the expression and diagnostic value of p27 and CD44V6 in ovarian carcinomas.Methods 54 cases of ovarian carcinoma were examined by immunohistochemical two-step-system method for p27 and CD44V6.Results The positive rates of p27 and CD44V6 is 37.0 %(20/54),42.6 %(23/54) respectively.The positive rates of p27 is 20.0 %,12.0 % and 8.7 % in clinic stage Ⅲ~Ⅳ,poorly differentiated tumors and lymphnode metastasis group compared with 68.4 %,58.6 % and 58.1 % in clinic stageⅠ~Ⅱ,well differentiated tumors and lymphnode negative group(P

Objective To study the expression and clinical significance of p16 and p27kip1 in endometrial carcinoma. Methods 65 cases of endometrial carcinoma were examined by immunohistochemical method for p16 and p27kip1. Results The positive rates of p16 and p27kip1 was 47.7 % and 41.5 % respectively. Both the expression of p16 and the expression of p27kip1 were correlated with histologic differentiation. Conclusions p16 and p27kip1 may play important roles in the development of endometrial carcinoma. They were important in predicting the prognosis and directing the treatment of endometrial carcinoma.

Objective To investigate the effect of pretend play training based on Learn to Play program on pretend play capabilities of children with autism. Methods The researchers referred some training strategies in Learn to Play program, and designed a pretend play train-ing which adapted to autistic children's level of development. And then they conducted the pretend play training on three autistic children for four weeks. After that they used Child-Initiated Pretend Play Assessment to assess the effect of the intervention before, after and two weeks after training. Results The percentage of pretend play actions, the number of object substitutions and the number of imitated actions in-creased in some degrees in the children. Conclusion The pretend play training based on Learn to Play program can promote the pretend play capabilities of children with autism.

At present, ischemie stroke is one of the main diseases of the highest mortality and disability in the world. However, the traditional treatment methods (for example, thrombolytic therapy) have some disadvantages, such as narrow time window, and poor efficacy. As a cell therapy, cord blood stem cell transplantation has brought hope to the treatment of refractory nervous system diseases.

Thrombolytic therapy is a main treatment method for ischemic stroke.Intravenous recombinant tissue-type plasminogen activator (rtPA) is the only FDA-approved therapy for acute stroke; however,its clinical application has been limited because the narrow therapeutic time window and the presence of the risk of hemorrhagic complication.In order solve these problems,a large number of clinical trials have started to focus on the studies of intra-arterial thrombolysis,mechanical thrombolysis and sonothrombolysis.

Objective To compare the reduction in left ventricular hypertrophy (LVH) caused by monotherapy with ramipril or losartan or the combination of these two drugs,in patients with hypertensive LVH and to evaluate the value of three-dimensional echocardiography (3DE) on LVH regression.Methods Ninety-six essential hypertensive patients with LVH were enrolled in this study.All patients were randomly divided into 3 groups: ramipril group,losartan group,combination group with ramipril and losartan.Left ventricular mass(LVM) was calculated by M-mode echocardiography,two-dimensional echocardiography and 3DE at baseline and after 6 months treatment with ramipril or losartan.Results Of 96 patients enrolled,59 patients have complete follow-up datum.LVM of ramipril,losartan and combination group decreased 16.9% , 17.9% and 18.8% compared with before treatment.LVM by 3DE decreased 11.6% , 14.7% and 13.6% respectively.The difference of LVM derived from 3DE showed obviously lower than derived from M-mode echocardiography.Conclusions Applying M-mode echocardiography and two-dimensional echocardiography to evaluate the regression of LVH will overestimate the effects of drugs.Three-dimensional echocardiography may detect the changes of LVM more accurately.

Objective To evaluate the effects of angiotensin converting enzyme inhibition(ACEI) or angiotensin II receptor blocker(ARB) on coronary hemodynamics in hypertensive patients with left ventricular hypertrophy(LVH) by Doppler ultrasound.Methods Sixty essential hypertensive patients with LVH were enrolled in this study.All patients were randomly divided into 3 groups: ramipril group,losartan group and combination group.Left ventricular mass(LVM) was calculated by three dimensional echocardiography and coronary hemodynamics was evaluated by transesophageal echocardiography with left anterior descending artery.Coronary flow reserve(CFR) was calculated as the ratio of coronary flow velocity,after intravenous injection of dipyridamole,to rest peak velocity.All the indexes of the coronary hemodynamics were corrected by LVM.Results Fifty patients had complete follow up datum.The systolic blood pressure(SBP),diastolic blood pressure(DBP) and LVM were significantly decreased in ramipril,losartan and combination group after 6 months′ treatment (All P

Regional microenviroment hypoxia is a common feature in inflammation and malignancy. Cells are able to trigger an adaptive response to hypoxia conditions that result in hypoxia-inducible factor(HIF)overexpression. Based on a brief description of the structure and functions of HIF, this article discusses the relationship between inflammation, tumor and HIF.

Objective To observe the effects of statins, angiotensin-converting enzyme inhibitor/adrenergic receptor binder ( ACEI/ARB ) treatment on Heme Oxidase-1 ( HO-1 ) expression in patients with coronary artery disease. Methods HO-1 expression in periphery white blood cells was detected using Western blot before and after 3 months treatment of the above antioxidants in 60 patients who were diagnosed as coronary artery disease by coronary angiography. Results HO-1 expression measured by gray scale peak by western blot was significantly higher after 3 months antioxidant treatment than that before antioxidant treatment( 168. 9 t6. 8vs 112.7 ± 6.3, P = 0.008 ). Conclusion Effects of statins and ACEI/ARB in treating coronary artery disease may be due to its promoting expression of HO-1.

Objective To determine the feasibility of using a special auditory intervention to detect intraoperative awareness in children under general anesthesia. Methods Thirty-four ASA Ⅰ or Ⅱ children aged 5-15 yr weighing 16-73 kg undergoing scoliosis were enrolled in this study.Intraoperative wake-up test was performed during operation.Two easily identified animal noises(60 dB,lasting 15 s)were played through head phones before induction of anesthesia and immediately after the intraoperative wake-up test. Children were interviewed on the 1st and 5th-7th days after surgery to assess their awareness of intraoperative wake-up test and special auditory intervention. Results Four children were excluded from the study because of restlessness during the intraoperative wake-up test or their refusal to be interviewed. From the remaining 30 children,4 children were suspected to be aware of intraooperative wake-up test. Awareness was comfirmed in 3 children and suspected in one child.The incidence of awareness of intraoperative wake-up test was 10%.But only one of them could tell the animal sound played during the wake-up test.All the patients in this study had explicit recall of the animal noises played before induction of anesthesia.Conclusion Special auditory intervention can not detect intraoperative awareness in children unnder general anesthesia.
