Purpose:To investigate the relationship between cell apoptosis and dephosphorylated RB protein in human breast cancer. Methods:In our work,human breast cell lines (MCF-7/S,the chemosensitive cell line and MCF-7/ADR,the chemoresistent cell line)were evaluated. Chemosensitivity of two cell lines was evaluated by the MTT colorimetric assay;the expressive levels of dephosphorylated RB protein were detected with immunocytochemistry. Apoptosis rates were determined by flow cytometry(FCM). Results:ADR inhibited proliferation of chemosensitive cell line MCF-7/S ,the 50% inhibition concentration (IC 50 ) was 0.128 ?g/ml;And IC 50 of MCF-7/ADR was 10.89 ?g/ml. The chemotherapeutic sensitivity of MCF-7/S was more than that of MCF-7/ADR by 86 times . Before treatment with ADR,phosphorylated RB protein was positive in two cell lines,but dephosphorylated RB protein was negative;After treatment of different concentration ADR,when the concentration of ADR was increased,expression of dephosphorylated RB protein elevated accordingly in MCF-7/S,but no significant change in MCF-7/ADR. Apoptosis and cell cycle was detected by FCM assays shows ADR induced apoptosis of MCF-7/S more than MCF-7/ADR(P0.05).

OBJECTIVETo observe the therapeutic effect of Jiangzhi Tiaoya Granule (JZTYG) in treating essential hypertension and its protection on function of vascular endothelial cells (VEC).

METHODSFifty-nine patients of essential hypertension divided into two groups were treated with JZTYG (the treated group) and Jinjia Yixintong (the control group) respectively. The changes of symptoms, signs, blood pressure, heart rate were observed and the levels of endothelin (ET), calcitonin gene related peptide (CGRP) content were determined by radioimmunoassay (RIA).

RESULTSThe total effective rates of JZTYG in lowering blood pressure and improving symptoms were both 90.0%, markedly effective rate in lowering blood pressure and improving symptoms was 36.7% and 60.0% respectively. The symptom improved in the treated group was better than that in the control group (P < 0.05). It also could reduce the plasma ET level (P < 0.05) and ET/CGRP ratio (P < 0.01), and increase the CGRP level (P < 0.05).

CONCLUSIONJZTYG has a promising clinical therapeutic effect in treating essential hypertension and is able to protect the VEC function.

Objective To evaluate the clinical efficacy of noninvasive positive pressure ventilation (NPPV) in the treatment of patients with acute respiratory distress syndrome (ARDS), and to look for the predictors of failure of NPPV. Methods A retrospective observation was conducted. ARDS patients underwent NPPV admitted to emergency intensive care unit (EICU) of Guangdong General Hospital from January 2013 to December 2015 were enrolled. The patients were divided into success group and failure group according to the clinical efficacy. The condition of the patients in the two groups was evaluated, and ARDS classification and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score before treatment were recorded. Etiological composition of ARDS was analyzed. The parameters, including heart rate (HR), respiratory rate (RR), oxygenation index (PaO2/FiO2), arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2) and arterial oxygen saturation (SaO2), were recorded before and 2 hours after the treatment of NPPV. Multivariate logistic regression analysis was conducted for predicting the independent factors inducing the failure of NPPV treatment of patients with ARDS. Results The date of 137 patients with ARDS were collected, excluding the followed patients, 6 with coma, 18 with hemodynamic instability, 5 with severe hypoxia, and 5 with incomplete date. Finally, a total of 103 patients entered the statistics. There were 69 patients in NPPV success group, and 34 in failure group. Compared with success group, APACHE Ⅱ score in the failure group was higher (21.4±6.2 vs. 19.7±8.9), the ratios of patients with severe ARDS and those induced by pulmonary infection were higher [82.4% (28/34) vs. 5.8% (4/69), 32.4% (11/34) vs. 8.7% (6/69), respectively, both P < 0.05]. HR and RR before NPPV in the failure group were significantly higher than those of success group [HR (bpm): 124±13 vs. 117±12, RR (bpm): 39±5 vs. 33±4], and PaO2/FiO2, PaO2, PaCO2, and SaO2 were significantly lower than those of the success group [PaO2/FiO2 (mmHg, 1 mmHg = 0.133 kPa): 104±10 vs. 156±12, PaO2 (mmHg): 53±8 vs. 68±7, PaCO2 (mmHg): 31±5 vs. 37±7, SaO2: 0.83±0.07 vs. 0.91±0.05, all P < 0.05]. It was shown by logistic regression analysis that severe ARDS [odds ratio (OR) = 10.533, 95% confidence interval (95%CI) = 5.847-89.852, P = 0.000], pulmonary infection resulted ARDS (OR = 4.831, 95%CI = 1.688-13.825, P = 0.003) and PaO2/FiO2 < 140 mmHg 2 hours after treatment (OR = 7.049, 95%CI = 1.266-39.236, P = 0.026) were the independent risk factors of NPPV failure for the treatment of patients with ARDS. Conclusions Patients with severe ARDS and pulmonary infection derived ARDS were the risk factors of failure to NPPV in ARDS. Lack of improvement in oxygenation 2 hours after NPPV is the predictor of NPPV failure and change to invasive ventilation.

ObjectiveTo investigate the expression of programmed death receptor ligand 1 ( PD-L1 ) of peripheral blood mononuclear cells (PBMCs) in patients with hepatic cystic echincccccosis (HCE) and its relation with interferon-γ.MethodsThe clinical data of 63 patients with HCE who were admitted to the First Affiliated Hospital of Xinjiang Medical University from June 2010 to February 2011 were retrospectively analyzed.All patients were divided into HCE active group (38 patients) and HCE non-active group (25 patients) according to the system established by the World Health Organization's Informal Working Group on Echinocoecosis.Twenty patients with hepatic hemangioma or healthy individuals were recruited in normal control group.The positive rate of PD-L1 expression was detected by flow cytometry and immunocytochemistry.The expression of interferon-γ was detected by enzyme-linked immtmosorbent assay (ELISA).All data were analyzed by the t test,one-way analysis of variance,LSD test and chi-square test.The relationship between the expression of interferon-γ and positive rate of PD-L1 expression was analyzed by the Pearson test.ResultsThe results of flow cytometry showed that the positive rates of PD-L1 expression in the HCE active group,HCE non-active group and normal control group were 12.1％±3.8％,10.9％ ± 2.5％ and 9.1％ ±2.5％,respectively.There was a significant difference in the positive rate of PD-L1 expression between the HCE active group and normal control group (t =3.327,P ＜ 0.05 ).The results of immunohistochemistry showed that the positive rates of PD-LI expression in the HCE active group,HCE non-active group and normal control group were 11.9％ ± 3.4％,i0.6％ ± 2.9％ and 9.5％ ± 3.6％,respectively.There was a significant difference in the positive rate of PD-L1 expression between the HCE active group and normal control group (t =2.470,P ＜ 0.05 ).The expressions of intefferon-γ in the HCE active group,HCE non-active group and normal control group were ( 141 ± 38 ) μμg/L,( 124 ± 32 ) μg/L and ( 105 ± 42 ) μg/L.There wasasignificant difference in the expression of interferon-γ between the HCE active group and normal control group ( t =3.280,P ＜ 0.05).The results of flow cytometry and immunohistochemistry revealed that the positive rate of PD-L1 expression was positively correlated with the expression of interferon-γ( r =0.59,0.61,P ＜ 0.05 ).Conclusion With the help of interferon-γ,PD-L1 may play an important role in promoting the immune.evasion of echinococcus.

Bacillus subtilis B6-1 was used as an original strain for mutagenic treatment and a defined medium was used as the selective medium. A mutant named B. subtilis W003 was isolated after three serial ultraviolet (UV) irradiations and one diethyl sulfate (DES) treatment. The ?-PGA yield on a rotary shaker was enhanced from 10.9 g/L in parental strain to 20.5 g/L in the mutant. It was illustrated by single factor experiments that the optimal carbon and nitrogen sources were glucose and (NH4)2SO4 respectively. The optimal fermentation medium was achieved by orthogonal test. In the optimal medium, a ?-PGA yield of 45.3 g/L was obtained after 36 h cultivation.
