Objective To analyze the effects of curcumin combined with cisplatin on the growth and lymphatic metastasis of cervical cancer xenografts in nude mice.Methods The human cervical carcinoma Caski cells xenotransplanted tumor models were established.Inoculated mice were randomly divided into 4 groups according to random number table:control (normal saline 10 ml/kg),Cur (curcumin 100 mg/kg),Cis (cisplatin 3 mg/kg) and Cur + Cis group (100 mg/kg curcumin +3 mg/kg cisplatin).The tumor volume and anti-tumor rate were calculated.The mRNA levels of macrophage migration inhibitory factor (MIF) and vascular endothelial growth factor-C (VEGF-C) were analyzed by real-time fluorescent quantitative polymerase chain reaction (PCR).Results The inhibitory rates of Cur group,Cis group and Cur + Cis group were 40.8％,53.3％ and 60.0％.After 15 days treatment,the tumor volumes of the control group,Cur group,Cis group and Cur + Cis group were (123.44 ± 35.62),(71.72 ± 28.36),(65.47 ± 18.32),(53.44 ± 10.79) mm3.The growth rates of tumor volume in Cur group,Cis group and Cur + Cis group were slower,Cur + Cis group could more effectively inhibit tumor volume growth.The difference among the four groups had statistically significance (F =16.890,P =0.000).Real-time fluorescent quantitative PCR detection showed that compared with the control group (1.000),the MIF mRNA expressions in Cur group,Cis group and Cur + Cis group were 0.322 ±0.094,0.154 ± 0.006 and 0.136 ± 0.007,VEGF-C mRNA expressions in the three groups were 0.312 ± 0.068,0.263 ± 0.072 and 0.221 ± 0.041.The differences among groups had statistically significance (F =220.279,P =0.000;F =143.250,P =0.000).MIF mRNA was positively related with VEGF-C mRNA (r =0.815,P =0.001).Conclusion Curcumin combined with cisplatin can inhibit the growth of Carski cell xenografts in nude mice.Through the down-regulating expression of MIF mRNA and VEGF-C mRNA,cisplatin and curcumin can inhibit the lymphatic metastasis of cervical cancer,and it may be one of the important mechanisms of its anti-tumor effects.

ObjectiveTo investigate the amount of bacteria and the expression of amylase and lipases in the drainage fluid in patients with intestinal fistulas with time courses.MethodsThe samples were collected from 16 patients with high intestinal fistulas from July 1998 to January 2008.The amounts of bacteria from the drainage fluid were measured 0,2 and 4 hours after taking out from the patients.At the respective time points,the intestinal juices were also collected to measure the amylase and lipase expressions.After reinfusion of succus entericus,thelevels of albumin,prealbumin,transferring,and fibronectin were measured at 0,7,and 14 days,ResultsThere was no significant increase of bacteria in the drainage fluid within 4 hours ( F(0,2) =18 812.50,P ＞ 0.05 ; F(0,4) =387 625.00,P ＞ 0.05).and there was no change in the expressions of amylase ( F(0,2) =190.60,P ＞ 0.05 ;F(0,4) =631.75,P＞0.05) and lipase within 4 hours (F(0,2) =204.10,P＞0.05; F(0,4) =1080.05,P＞0.05).After succus entericus reinfusion,the fibronectin (F(0,14) =74.24,P ＜ 0.01 ; F(7,14) =59.78,P ＜0.01),transferring (F(0,14) =0.46,P ＜ 0.01 ; F(7,14) =0.39,P ＜ 0.05 ),and prealbumin ( F(0,14) =54.37,P ＜ 0.05) were increased significantly.ConclusionsBacteria and enzymes do not increase in the drainage fluid within 4 hours in patients with intestinal fistulas.Therefore,it is safe and effective to reinfuse succus entericus.

Objective To observe the efficacy of combinated inhaled glucocorticosteroid and long- ?2 - agonist for asthmatic children. Methods Forty- seven children with moderate or severe persistent asthma were treated with inhalation of the fluticasone pro-pionate and salmeterol. The PEF value and the mark according the symptom of asthma before and after treatment( week and month respectively) were recorded. At the same time the days of treatment the patient with the short - ?2 - agonist in the first week and the forth week respectively were noted. The subjective feeling and accident of patients also should be paid attention. Results There was significant difference (P

Objective To explore the mechanism of ischemic postconditioning in relieving cerebral ischemia reperfusion (IR) by regulating autophagy through P38MAPK pathway.Methods Cerebral ischemia reperfusion model was established by using modified Pulsinelli four-vessel occlusion (4-VO).Totally 128 male SD rats were divided into 4 groups randomly:control group (sham),cerebral ischemia reperfusion model group (CIR),cerebral ischemic postconditioning group (CIP),and cerebral ischemic postconditioning + P38MAPK inhibitor group (SB203580 group).Each group was subdivided into four time points:6 h,24 h,48 h,and 72 h.The morphological changes of the hippocampus CA1 area neurons at each time point and the number of surviving nerve cells were detected with HE staining.The expression of the hippocampus CA1 area phosphorylated P38MAPK and the autophagy-related genes of Beclin-1 and LC3-Ⅱ were detected with immunohistochemistry.The protein content of the hippocampus phosphorylated P38MAPK and autophagy-related genes of Beclin-1 and LC3-Ⅱ were detected with Western blotting.Results Compared with those in sham group,the damage of rats' hippocampal neuron structure and the survival rate of neurons at each time point decreased in CIR group,the expressions of p-P38MAPK,LC3-Ⅱ and Beclin-1 increased.Compared with those in CIR group,in CIP and SB203580 groups the structure of rats hippocampal neurons was improved,the survival rate of neurons increased,the expression of p-P38MAPK decreased and the expressions of LC3-Ⅱ and Beclin-1 increased at each time point.Compared with CIP group,SB203580 grouphad improved structure of rats' hippocampal neurons,increased survival rate of neurons,decreased expression of p-P38MAPK,and increased expressions of LC3-Ⅱ and Beclin-1 at each time point.Conclusion Cerebral ischemic postconditioning through inhibiting P38MAPK pathway can regulate autophagy and exert its nerve-protective effect.

Objective To study the effect of the deferoxamine mesylate on the prognosis of patients with intracerebral hemorrhage(ICH) after one year. Methods From February 2013 to May 2014,spontaneous ICH patients diagnosed by computed tomography ( CT ) within 18 hours of onset in Mancheng District Hospital of Baoding were evaluated. Patients were randomly divided into experimental group and control group. The treatment of the two groups was similar except that the experimental group received deferoxamine mesylate. Patients were e?valuated by CT and neurology scale( NIHSS scale,GCS scale) at the time of admission and followed up for the first year by the RANKIN( mRS) scale. All clinical data of the two groups were compared. Results Forty?two patients were included in the study, including 21 cases in the experimental group and 21 cases in the control group,there was no significant difference in baseline data between the two groups at admission. There were 6 pa?tients with mRS ≥3 in the experimental group, and 6 patients with mRS ≥3 in the control group after one year. There was no statistically significant difference in the distribution of mRS score between the two groups after one year admission( P=1. 000) . Conclusion There may be no helpful on the prognosis of patients with intrace?rebral hemorrhage by intravenous infusion of deferoxamine mesylate,the further study is needed.
