Objective: To explore the clinical efficacy of positive airway pressure biphasic (BiPAP) non-invasive ventilation for treating the patients with severe pre-eclampsia combining acute heart failure (AHF).
Methods: A total of 84 patients with severe pre-eclampsia combining AHF treated in our hospital from 2008-01 to 2014-12 were retrospectively studied. The patients were divided into 2 groups: Control group, the patients received routine treatment for pre-eclampsia and AHF,n=41 and Observation group, based on routine treatment, the patients received assistant BiPAP ventilation,n=43. The changes at before and 3h after treatment of cyanosis, dyspnea, pulmonary rales, heart rate (HR), respiratory rate (RR), arterial oxygen saturation (SaO2), arterial partial pressure of oxygen (PaO2), arterial carbon dioxide partial pressure (PaCO2), pH value and plasma levels of BNP were compared between 2 groups.
Results:①Comparison of before vs after treatment in both groups: HR (times/min) in Control group (90±8 vs 110±14) and Observation group (80±6 vs 112±12); RR (times/min) in Control group (24±5 vs 33±8) and Observation group (18±4 vs 35±7); PaCO2 (mmHg) in Control group (41.3±4.3 vs 48.4±5.6) and Observation group (29.7±5.4 vs 47.8±3.9); BNP (ng/L) in Control group (87.50±8.00 vs 133.00±8.00) and Observation group (69.50±8.30 vs 138.00±6.92); SaO2 (%) in Control group (93.0±3.7 vs 80.5±4.7) and Observation group (97.1±3.4 vs 81.2±4.2); PaO2 (mmHg) in Control group (80.3±5.8 vs 80.5±4.7) and Observation group (89.1±6.2 vs 53.2±5.4), allP<0.05.②After treatment, compared with Control group, Observation group presented obviously decreased HR, RR, PaCO2 and BNP; signiifcantly increased SaO2 and PaO2, allP<0.05. PH was similar between 2 groups,P>0.05.
Conclusion: Assistant BiPAP ventilation may treat the patients with severe pre-eclampsia combining AHF, it could improve HF symptom and hypoxia. The clinical signiifcance should be conifrmed by further investigation.

Patients with advanced gastric cancer lose the surgical indications.Chemotherapy can improve the overall survival and quality of life,which is the main treatment option.But there is no standard chemotherapy regimen for the patients with advanced gastric cancer.Since its initial approval,S-1 is widely used in gastric cancer.Several studies were performed to explore combinations of S-1 with other cytotoxic drugs such as platinum,docetaxel,paclitaxel,and irinotecan.All these combinations were found to be promising,with response rates of around 40％-50％ and relatively favorable safety profiles.

Objective To evaluate the effect of embelin combined with paclitaxel on the inhibition of A 549 lung cancer cell proliferation and tumor growing in tumor bearing nude mice. Methods The anti-proliferation efficiency of embelin combined with paclitaxel were evaluated by MTT assay, and A 549 cell apoptosis were evaluated by lfow cytometry. A 549 cells were xenografted in mice to establish the animal model, which were used to evaluate the effect of anti-tumor. Results compared to saline group、embelin group and paclitaxel group, the (paclitaxel+embelin) group could inhibit the growth of A 549 cells effectively(P<0.05). The embelin combined with paclitaxel induced the apoptosis of A 549 cells more effective than paclitaxel alone. The (paclitaxel+embelin) group significantly inhibited the growth of tumor tissue. Conclusion the paclitaxel can inhibit the growth of A 549 cells, the embelin can induce the apoptosis of A 549 cells, and the combination of paclitaxel and embelin may be a potentially effective treatment for lung cancer.

Objective To investigate the protective role of Xiongbitong capsule against liver injury in hyperlipemic rats.Methods Sixty Wistar male rats were randomly divided into 5 groups(12 rats in each group): a blank group, a model group, a simvastatin group(10 mg/kg, 2 ml intragastric administration daily), a Xiongbitong capsule high-dose group(25 mg/kg, 2 ml intragastric administration daily), and a Xiongbitong capsule low-dose group(12.5 mg/kg, 2 ml intragastric administration daily). Hyperlipidemia model in rats was indeuced by hyperlipidemic diet. The simvastatin group was intragastric administrated with simvastatin suspension 2 ml(10 mg/kg daily), and the rats in the control group and the model group were intragastric administrated with equal volume of saline. After 10 weeks, the serum leves of total cholesterol(TC), triacylglycerol(TG), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol (HDL-C), nitric oxide(NO), endothelin1(ET-1), and the whole blood viscosities(high-, medium-, low-shear)were measured. Liver injury were evaluated with histopathologic examination by H.E. staining. The expressions of intercellular adhesion molecule-1(ICAM-1), monocyte chemoattractant protein-1(MCP-1)in hepatic tissue were measured by immunohistochemical staining.Results The serum leves of TC(1.47± 0.10 mmol/Lvs. 3.48±0.19 mmol/L), TG(0.38±0.11 mmol/Lvs. 0.95±0.14 mmol/L), LDL-C(1.48± 0.18 mmol/Lvs. 2.39±0.22 mmol/L), ET-1(145.81±18.65 pg/mlvs. 177.70±17.70 pg/ml) in the Xiongbitong capsule high-dose group were significantly lower than those in the model group(allP<0.01), HDL-C(1.21±0.14 mmol/Lvs. 0.65±0.10 mmol/L)and NO(31.28±2.36μmol/Lvs. 19.61±1.28μmol/L) significantly lower than those in the model group(allP<0.01), the expressions of ICAM-1(0.133±0.019vs. 0.187±0.011)and MCP-1(0.153±0.014vs. 0.264±0.020)significantly lower than those in the model group(allP<0.01). The liver injury in the Xiongbitong capsule high-dose group decreased than that in the model group. Conclusions Xiongbitong capsule can protect against liver injury via regulating lipid metabolism, protecting endothelial function and down regulating expressions of MCP-1 and ICAM-1.

Objective To investigate the changes of the level of oxidative stress and cell apoptosis of secondary brain injury after traumatic brain injury,and the influence of brain-derived neutrophic factor on these parameters in rats,as well as its potential mechanisms.Methods A total 84 adult and healthy male rats was divided randomly into 2 groups:control (n =42) and traumatic brain injury (TBI) groups (n =42).The brain-derived neurotrophic factor (BDNF) group was induced using improved Feeney method and was received abdominal injections of BDNF (0.5 μg/μl) immediately after injury,the control group were received abdominal injections with the same dose sodium chloride injection immediately after injury and repeat one time everyday until the rats was killed.Each group was divided into seven subgroups by sacrificed time after injury,those are 1 h,3 h,6 h,12 h,24 h,3 d,and7 d,each subgroup got6 rats.Each subgroup was randomly selected three rats after being killed.The water content,superoxide dismutase (SOD),malonic aldehyde (MDA),and glutathione (GSH) of rats were measured contusion peri tissues brain tissue.Specimens were taken from left three rats of subgroup,which was part of the brain tissue.The expression of NF-κB p65,around the brain tissue with immunohistochemical methods were detected.TdT-mediated dUTP nick-end labeling (TUNEL) method was used to observe the peri cell apoptosis after brain contusion.Results NF-κB p65 was expressed obviously around the lesion in 1h group,and strongly expressed in TBI-3 h-12 h,and reached a peak in 24 h after the injury,while NF-κB p65 expression reduced in TBI-3 d-7 d,and still in high expression.NF-κB p65 expression strongly correlated with the degree of cerebral edema (r =0.651,P ＜0.05).For two groups,NF-κB p65 expression strongly correlated with the level of MDA (r1 =0.947,P ＜0.01;r2 =0.961,P ＜0.01).Conclusions Changes of NF-κB protein expression after brain injury were involved in a series of pathological processes of secondary brain injury,such as oxidative stress,and apoptosis,brain-derived neutrophic factor is probably through inhibit oxidative stress levels,control apoptosis,prevent the development of vasogenic cerebral edema,and reduce or mitigate secondary brain injury.
