Objective:To detect and analyze the membrane estrogen receptor(mER)in primary cultured interstitial cells of Cajal(ICC).Methods:Interstitial Cells of Cajal(ICC)'s surface binding sites for 17-?estradiol(E2)were detected by cell-impermeant ligand using confocal microscopy.Radioligand binding assay and Scatchard software were used to analyzed the characteristics of mER.Results:Immunofluorescence shows the staining pattern of nonfixed,nonpermeabilized ICC incubated with E2BSAFITC.The radioligand binding assay were analyzed by Scatchard software,The Bmax of mER was 45.75 fmol/mg protein and the kD was 0.717 3 nmol/L.Conclusion:A form of the estrogen receptor is present within the cell membrane of ICC and maybe capable of mediating rapid effect of estrogen.

Objective To investigate the influence of trimetazidine combined with atorvastatin on heart func-tion and the BNP level in patients with cornary heart failure.Methods The clinical data of 400 patients with cornary heart disease were retrospectively analyzed.194 patients in the control group were treated with conventional treatment, 206 patients in the observation group were treated with trimetazidine combined with atorvastatin on the basis of the control group.The treatment effect,cardiac function and BNP level were observed and compared.Results The effec-tive rate of the observation group was 91.26%,which was significantly higer than 76.29% of the control group (χ2 =16.667,P <0.05).After treatment,the cardiac index,stroke volume,cardiac output,left ventricular ejection fraction and BNP level of the two groups were significantly higher than before treatment,and those in the observation group were significantly higher than the control group(t =2.505,2.851,3.308,3.452,all P <0.05).Conclusion Trime-tazidine combined with atorvastatin in treatment of cornary heart failure has good curative effect,it can reduce the serum level of BNP,improve cardiac function significantly,which is of great value for clinical use.

Objective To explore the distribution and characterization of class 1 integrons in E.coli from healthy feces,and to elucidate the status of gene-cassettes.Methods Routine method was used to isolate E.coli,antibiotics susceptibility was tested by the disk diffusion method;class 1 integron was detected by PCR assay;PCR products were sequenced and analyzed.Results Of 97 samples,76 isolates were identified,and 25 isolates were multiple-drug resistant.The antibiogram was sulfamethoxazole-trimethoprim,ampicillin,streptomycin,tetracycline,erythromycin.14 of 25 isolates carried class 1 integrons,and the size of integrons differed from 1 800 bp(10 strains) to 750 bp(4 strains).The sequenced PCR product demonstrated that the 1 800 bp integron laboured aadA1-dfrA14-orf gene cassette conferred the resistance to sulfamethoxazole-timethoprim,streptomycin and aminoglycoside;the 750 bp integron laboured dfrA14 gene cassette conferred the resistance to sulfamethoxazole-trimethoprim.Conclusion The different kinds of class 1 integrons exist in E.coli from the healthy students,and determine the multiple-resistant antibiotics.

Owing to the advanced age,limb hemiplegia,dehydration,and vessel wall injury,stroke may be easy to cause venous thromboembolism (VTE).VTE mainly include deep vein thrombosis (DVT) and pulmonary embolism (PE).DVT refers to abnormal blood clotting in the veins and impedes venous return.The dislodgement of emboli from the vessel wall can form a thrombotic embolism,and cause PE,myocardial infarction,and stroke; it can not only prolong hospitalization,but also increase the mortality.This article reviews the incidence,risk factors,treatment,and prevention of DVT after a stroke.

Recent studies show that autophagy ont only plays an important role in maintaining homeostasis in cells,but also palys a double role in the tumorigenesis and development of cancer.Studying the molecular mechanisms of autophagy and the relationship between autophagy and cancer have great significance for cancer treatment and prevention.

ObjectiveLamiophlomis rotate is the rare perfumes Tibetan medicine.This article aimed to explore the current research of Lamiophlomis rotate on the base of literature.MethodsEstablish database of researching literature on Lamiophlomis rotate in domestic published between 2000 and 2010.Results Altogether 210 articles distributed in 112 kinds of journals were found.These articles involved with 8 areas of clinical research(113 article),pharmacological research(18 article),component analysis(35 article),preparation process (15 article),breed and cultivation of seeds (4 article),new drug testing (3 article),biological characteristics and drug economics.32 articles gained fimancial assistance from fund.Three articles on breed and cultivation of seeds gained financial assistance from fund,occupying 75.00％ of such research.Conclusion There were few articles published in core journals,besides relatively scattered distribution of researching institute and journals.Studies on breed and cultivation of seeds should be strengthened.

The research of the secondary damage remote from middle cerebral artery territory infarction has made significant progress in recent years.More animal experiments from the cellular,biochemical and molecular levels have been performed for in-depth and detailed research on remote site damage. The injury mechanisms such as oxidative damage and β amyloid deposition have been found.The new imaging detection technologies,such as magnetic resonance diffusion tensor imaging(DTI),have gradually been applied to the diagnosis of remote site damage.

Objective To compare the influence of two different managements of relief incision (exposed relaxation therapy or absorbable hemostatic gauze) in infants' palatoplasty. Methods A total of 118 infants with cleft palate between 5- to 8-month-old for the study were randomly divided into two groups: group A was exposed therapy group, and in group B both sides of relief incision were placed absorbable hemostatic gauze. The wound bleeding, body temperature, diet and incidence of fistula were observed and analyzed after operation. Results There was no significant difference between the two groups in postoperative temperature, diet and wound healing (P>0. 05). The postoperative wound bleeding was statistically significant differences between the two groups (P<0. 05). Conclusions Either exposed therapy or placed absorbable hemostatic gauze in relief incision, has minimal systemic and local reactions in the postoperative infant. The advantages of exposed treatment are economic and simple, and less irritant to the wound.

Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease in terms of molecular pathogenesis and cell of origin. Earlier prognostic models relied mainly on such clinical variables as age, stage of disease, and performance status, which did not display its heterogeneity. Many studies have reported that some biomarkers could be used for prognostication, while older prognostic models need to be revalidated and modified as improved therapeutic options become available. In this review, we discussed pertinent studies on individual biomarkers and pattern-based biomarker models, with an emphasis on markers evaluated in patients treated with rituximab-containing chemotherapy.

Objective To explore the key points of nursing for neonates with hypoxic-ischemic encephalopathy detected by 18F-fluorodeoxyglucose positron emission tomography.Methods The features of nursing for 58 cases neonates with hypoxic-ischemic encephalopathy detected by 18F-fluorodeoxyglucose positron emission tomography were analyzed and summarized.Results 55 cases with hypoxic-ischemic encephalopathy detected by 18F-fluorodeoxyglucose positron emission tomography smoothly with pertinent nursing,only 3 cases had not completed the procedures because of change of their conditions.Conclusions Pertinent nursing was important for neonates with hypoxic-ischemic encephalopathy detected by 18F-fluorodeoxyglucose positron emission tomography because it could help them complete the procedures smoothly and make the results more accurate and satisfying so it is worthy of wide use clinically.
