Objective To investigate the incidence and its related factors of apathy in patients with acute ischemic stroke. Methods A total of 100 consecutive cases of ischemic stroke patients and 50 health controls were recruited in the present study. Apathy was assessed using modified apathy evaluation scale (MAES). According to the MAES score, acute ischemic stroke patients were divided into apathy group (MAES was more than 14 points) and non-apathy group. The differences of general information, clinical data, national institutes of health stroke scale (NIHSS), Montreal cognitive assessment (MoCA), Hamilton depression scale (HAMD), modified rankin scale (mRS) and the lesion location were compared between the two groups. Differences that showed statistical significance (P<0.05) went into the multi-factor analysis. The Logistic regression analysis was used to estimate the influence factors of apathy. Results There were 34 cases of apathy in patient group (34.00%), which was significantly higher than those of control group (3 cases of apathy, 6.00%, P<0.001). The age, incidence of diabetes, NIHSS score, HAMD score, lesions in brain stem and multiple lesions were significantly higher in apathy group than that of non-apathy group, while educational level, MoCA score were significantly lower ( P<0.05). The Logistic regression analysis showed that the higher MoCA score was a protective factor for apathy, while higher NIHSS score, lesions in brain stem and multiple lesions were risk factors for the incidence apathy. Conclusion The cognitive impairment, severity of neurological deficits, brainstem lesions and multiple lesions may be the risk factors of apathy after the occurrence of acute ischemic stroke.

Objective To better understand the relationship between doctors service quality and benefit in township public health centers so as to grasp the priorities of management and reform and promote the healthy development of the health cause. Methods The method of single factor analysis was combined with the method of stepwise logistic regression analysis. Results The study indicates that doctors delivering high quality service on average see more patients per day and contribute more to the business income and that service expenses are lower for patients seeking service from doctors who on average see more patients per day. Conclusion There is a positive correlation between doctors service quality and benefit in township public health centers.

Objective To study the regulatory T cells (Treg-cell) frequencies in patients with childhood acute leukemia and evaluate its clinical application value by investigating the relationship between the increasing numbers of Treg cells and minimal residual disease of leukemia (MRD), Methods Foxp3-FITC/CD25-PE/CD4-PerCP/CD3-APC four-color staining flow cytometry was established to identify Treg cells. Treg cells frequencies both in 10 healthy controls and in 33 patients with newly diagnosed childhood acute leukemia ( B-ALL 17 cases, T-ALL 9 cases, AML 7 cases) were detected. The possibility of the accumulation of Treg cells being the prognostic marker for acute leukemia was evaluated by comparing the results of Treg cells frequency with that of MRD. Results The percentage of Treg cells in CD+4 CD+3 T cells was M = 8. 09% in normal bone marrows, which was significantly different from the results in the bone marrows of newly diagnosed childhood acute leukemia ( M = 12.77% , U = 3.41, P < 0.01 ), but it showed no significantly differences among B-ALL, T-ALL and AML groups. No association was observed between the expression of Treg cells and clinical-biologic characteristics studied. In addition, Treg cells frequency in MRD positive group was significantly different from that in MRD continuously negative group ( M = 14. 74% vs M=11.3%, t =252.5,P<0.05). Conclusions Consistent with results from solid tumor, the study identifies a significantly increased numbers of Treg cells in patients with childhood acute leukemia. The situation of accumulation of Treg cells is closely associated with MRD results during chnical remission. High level of Treg cells may cause poor prognosis and increase the possibility of relapse.

Objective To establish a desirable quantitative assay system to evaluate the correlation between surgical manipulation and micrometastasis in primary esophageal cancer patients.Methods 118 pe- ripheral blood samples from 40 esophageal cancer patients undergoing radical resection were collected before surgery(B-1),immediately after surgery(B0)and at the third day postoperatively(B+3).Based on real-time quantitative reverse transcription-PCR,carcinoembryonic antigen(CEA)mRNA gene was used in the detec- tion.12 patients with benign tumor and 13 healthy volunteers were collected as negative control groups.Re- sults The median of CEA mRNA copies at B-1,B0 and B+3 were 1592,13 314 and 6221 copies/ml blood, respectively.CEA mRNA expression levels were found to be significantly higher at both B0 and B+3 than that of B-1(P=0.0001 and 0.0209,respectively).No significant difference was found between B0 and B+3(P= 0.4396).Conclusion Surgical manipulation on esophageal cancer patients increases the probability of mi- crometastasis.Therefore,adjuvant therapy is needed during perioperative stage.

Objective To investigate the effects and mechanisms of selective angiotensinⅡtype 1 receptor antagonist ZD7155 on the inhibition of pancreatic cancer in vitro.Methods MTT assays were used to determine the inhibition of pancreatic cancer cell line PaTu8988s by ZD7155 in different concen- trations and at different time.PaTu8988s cell cycle and cell apoptosis were detected by flow cytometry. Transmission electron microscope was used to investigate the apoptosis of PaTu8988s before and after the incubation with ZD7155 under different concentrations.PaTu8988s cell morphology was observed be- fore and after the incubation with ZD7155.Results MTT showed that the increase of inhibition of pan- creatic cancer cell by ZD7155 was in agreement with the increase of the concentrations of ZD7155 and the time of the incubation with ZD7155.The inhibition rates of PaTu8988s cells were 9%,18%,30%, 51%,60% and 78% by ZD7155 with the concentrations of 5?10~(-11),5?10~(-10),5?10~(-9),5?10~(-8),5?10~(-7) and 5?10~(-6) mol/L,respectively.The inhibition rates of PaTu8988s cells were 15%,25%, 36%,51%,67% and 85% by ZD7155 with the same concentration(5.0?10~(-8) mol/L)at 12,24,36, 48,60 and 72 hours,respectively.ZD7155 could also inhibit PaTu8988s cell cycle significantly and was dose-dependent.Cell electron microscopy showed that there were chromatin margination and apoptotic body in the cell nucleus when the cells were incubated with ZD7155,and these changes were increase with the concentrations of ZD7155.The morphology of PaTu8988s cell didn't have any change after in- cubation with ZD7155.Conclusions ZD7155 can inhibit the growth of pancreatic cancer cells in vitro by suppressing the S-phase of cell cycle and induce cell apoptosis without visible cell toxic effects.

Objective:To investigate the inhibitory effect of selective angiotensinⅡtype 1 receptor antagonist ZD7155 on pancreatic cancer xenografts of nude mice.Methods:Sixty nude mice were given subcutaneous injections of PaTu8988s cells to establish the pancreatic cancer xenograft models;then the animal models were evenly randomized into 3 groups:low-dose (10 mg?kg~(-1)?d~(-1))ZD7155,high-dose(20 mg?kg~(-1)?d~(-1))ZD7155 and normal saline groups.Ten mice in each group were sacrificed 10 d after treatment and the tumor sizes and body weights were measured.The microvessel density(MVD)was assessed by immunostaining of endothelial cells for CD31 and the cell apoptoses were observed by transmission electron microscope.Another thirty mice were treated for 30 days;the survival period of mice and toxicity of ZD7155 were observed till the 49th day of treatment.Results:Ten days after treatment,the mean tumor volumes in the control,low-dose and high-dose groups were(35.8?6.7)cm~3,(21.5?6.1)cm~3 and (10.7?4.1)cm~3,respectively(P
