Objective To analyze the rented factors leading to successful treatment of ectopic pregnancy by conservative therapy and to explore importance of this therapy. Methods 152 patients with ectopic pregnancy performed with conservative treatment were randomly recruited into a methotrexate plus Chinese medicine group, a 5-fluorouracil plus Chinese medicine group and a exclusive Chinese medicine group. The curative rate and side effect were observed in groups, and the relation between the treatment condition and the curative rate was analyzed. Results There was no difference in curative rate among groups, while the side effect in the exclusive Chinese medicine group was lower than other groups. It showed high curative rate in patients with two or more conditions of having mass less than 3 cm, the level of bloodβ-hCG less than 1000 IU/L, and the depth of posterior fomix effusion less than 1 cm. Conclusion Among the treatments of ectopic pregnancy, Chinese medicine has fewer side effects. Fully evaluation on the treatment condition can improve the curative rate.

Fibrosis is a pathological process characterized by tissue scars and can occur in many organs of the human body. Organ fibrosis is manifested by increased fibrous connective tissue and reduced parenchymal cells in organ tissues, which can lead to destruction of organ structures and reduced function, which seriously endangers human health. Current strategies for treating organ fibrosis include: blocking the transforming growth factor-β1 (TGF-β1)/Smad signaling pathway, anti-inflammatory, regulating the sphingosine kinase 1/sphingosine-1-phosphate (SK1/S1P) signaling pathway, antagonizing vasoactive peptide receptors, enzyme inhibitors, kinase inhibitors, inhibitors of cellular signaling pathway, regulation of metabolic pathways, and mesenchymal stem cell therapy. In the review, the treatment strategies for organ fibrosis and the latest developments in the research of anti-organ fibrosis drugs are summarized to provide a reference for the development of anti-organ fibrosis drugs.

Beta-Elemene is an antitumor drug which is isolated from the traditional Chinese medicinal herb Curcumae Phaeocaulis Rhizoma, it is the main component of elemene which is extracted from the plant and delivered via blood circulation after intravenous injection. The antitumor effect of beta-elemene in vitro and in vivo was definite, and beta-elemene could improve the patient immunity and no sever side effect, drug resistance or bone marrow suppression were found during the clinical studies. And human serum albumin (HSA) is a primary extracellular protein which has a high concentration distribution in blood plasma and has many characteristic physiological functions. Therefore, the binding of beta-elemene to protein may be very important for absorption, distribution, metabolism and elimination. Therefore, the study on the interaction of beta-elemene with drug-carrying protein is very important. In this work, molecular binding of beta-elemene to human serum albumin (HSA) was investigated by using spectrofluorometer. the binding constants suggested that a strong interaction and the formation of a complex between beta-elemene and HSA. This clearly implies that beta-elemene can be stored and removed by the proteins in the body. Furthermore, the fluorescence quenching results showed that the HSA fluorescence was quenched by beta-elemene through static quenching mechanism. Thermodynamic parameters showed that hydrophobic interactions play a role in the binding of beta-elemene to HSA. The negative deltaH(0) and positive deltaS(0) in case of beta-elemene therefore showed that electrostatic attraction play a role in the binding of beta-elemene to HSA.

Objective To investigate the effect of dexmedetomidine on the stress responses during wakeup test in patients undergoing cerebral functional area operation performed under propofol combined with remifentanil anesthesia.Methods Thirty-six ASA physical status Ⅰ or Ⅱ patients,undergoing cerebral functional area operation requiring wake-up test,aged 18-60 yr,weighing 50-70kg,were randomly divided into control group (group C) or dexmedetomidine group (group D) with 18 cases in each group.Dexmedetomidine 0.8 μg/kg was infused over 10 min before induction of anesthesia followed by infusion at 0.4 μg·kg-1 · h-1 in group D,while the equal volume of normal saline was infused in group C.Anesthesia was induced with target-controlled infusion of propofol and remifentanil and iv injection of cisatracurium.At 30 min prior to wake-up test,target-controlled infusion of propofol and application of mulscle relaxants were stopped,the target plasma concentration of remifentanil was decreased to 1 ng/ml,and in group D the infusion rate of dexmedetomidine was decreased to 0.1 μg·kg 1· h-1.Anesthesia time and consumption of anesthetics before wake-up test,wake-up time,and development of complications and intraoperative awareness during wake-up test were recorded.At 30 min prior to wake-up test (T1),immediately after wake-up (T2),at 5 min after wake-up (T3),and at 10 min after the anesthetic depth was deepened (T4),HR,mean arterial pressure and BIS value were recorded and blood samples were taken for determination of plasma concentrations of epinephrine (E) and norepinephrine (NE).Results Compared with group C,the consumption of propofol and remifentanil was significantly reduced before wake-up,the incidence of hypertension was decreased during wake-up test,and HR and plasma E and NE concentrations were decreased at each time point (P ＜ 0.05),and no significant difference in mean arterial pressure and BIS value was found in group D (P ＞ 0.05).Tachycardia,restlessness,bucking and awareness were not observed during wake-up test in group D.Conclusion Dexmedetomidine can inhibit the stress responses during wake-up test and raise the quality of wake-up test in patients undergoing cerebral functional area operation performed under propofol combined with remifentanil anesthesia.

AIM: To investigate the activation dynamics and the intracellular localization of p38 protein kinase in Raw264.7 cells after lipopolysaccharide (LPS) stimulation.METHODS: Protein kinase assay and immunogold electron microscope technique were used to check the activation dynamics and distribution of p38 MAPK in Raw264.7 cells before and after LPS stimulation. RESULTS: The kinase assay results showed that a marked increase in p38 activity was detected 15 min after LPS treatment, and reached maximal activity 30 min post stimulation, then dropped down and got closed to the pre-stimulated level 2 h later. The optimal LPS concentration for treatment was 100 ?g/L. The immunogold electron microscope data showed that p38 spread evenly in every part of the cytosol of the non-stimulated and EGF stimulated Raw264.7 cells, such as endoplasmic reticulum, mitochondria, lysosome, while the golden granules intensity in the cytosol area decreased and in the nuclear area increased significantly after LPS stimulation.CONCLUSION: p38 MAPK moves to the nuclei of Raw264.7 cells on account of stimulation by LPS.

Objective To elucidate the role of P38 signaling pathway on heat-induced apoptosis in monocytic cell line Raw264.7.Methods Raw cells were transfected with constitutively active mutant MKK6b(E)and dominant negative mutant P38(AF),or the empty cloning vector pcDNA3 and apoptosis was detected by flow cytometric analysis.Results The ectopic expression of P38 mutant was confirmed by immunostaining with the antibody against the Flag-epitope tag.Expression of MKK6b(E)led to a marked increase in P38 kinase activity in transfected cells and induced a 4-fold increase in the number of apoptotic cells as compared to that in cultures of control transfected cells.Meanwhile the expression of MKK6b(E)increased the apoptotic rate of Raw cells induced by heat.In contrast,the dominant-negative mutant P38(AF)inhibited Raw cells apoptosis induced by heat.Conclusion The activation of the MKK6-P38 MAP kinase signaling pathway is required for heat-induced apoptosis in Raw264.7 cells.

Objective To evaluate the MRI features of erythromycin eye ointment entered into the orbital soft tissue of guinea pigs.Methods MRI was performed dynamically to observe the signal changes 1 day,1 week,2 weeks ,3 weeks and 4 weeks after erythromycin eye ointment was successfully injected into orbital soft tissue of guinea pigs ,as well as HE stainings to monitor retrob-ulbar soft tissue specimens at each time point were obtained.Results After the injection of erythromycin eye ointment 1 day,1 week,2 weeks,3 weeks and 4 weeks later,the signal intensity of erythromycin eye ointment was resemble to the surrounding soft tissue and indistinguishable on T2 WI.On T1 WI,the signal intensity of erythromycin eye ointment was higher than that of contralat-eral adipose body of orbit at 1day and 1 week,and slightly higher than the contralateral adipose body of orbit at 2 weeks and 3 weeks,but resemblance at 4 weeks.HE staining showed that inflammatory cell infiltration and tissue necrosis at 1 day,the presence of foreign body macrophages and fibroblasts at 2 weeks,and the inflammatory cells surrounding the optic nerve gradually subsided at 3 weeks and 4 weeks.Conclusion Fat-suppressed T1 WI is the best sequence to observe erythromycin eye ointment.Abnormal signal changes on T1 WI can reflect the histopathological changes after erythromycin eye ointment into the tissue.
