Objective To investigate the effects of seven halothane and propofol anesthesia on heart rate and myocardial enzymes in elderly patients with coronary heart disease (CHD), and to analyze the safety of clinical application of the two kinds of anesthetic drugs.MethodsA total of 70 cases of elderly patients with coronary heart disease treatment January 2012 to December 2014 general anesthesia surgery as the research object, randomly divided into A group and B group were 35 patients in.A group were treated with seven sevoflurane anesthesia, group B patients were given propofol anesthesia, observe the change of the two groups of patients before and after anesthesia hemodynamic index and myocardial enzyme etc.index.ResultsA group of patients with HR 5min after induction and 10min were significantly lower than before the surgery, and the difference was statistically significant (P<0.05);HR stabilized after the induction of 15min and 20min, and compared with before surgery had no significant difference;patients in group B HR and 10min 5min after induction there was no obvious change compared with that before operation, no statistical significance;and after the induction of 15min and 20min HR increased, the difference was statistically significant (P<0.05).A group and B group in patients with systolic and diastolic blood pressure were lower than before anesthesia in varying degrees, and group B more significantly, the difference was statistically significant (P<0.05).A group and B group of patients after 6 h, cTnl and CK-MB in 12h and 24h than 15min before surgery has increased significantly, and A group cTnl and CK-MB were lower than B group, the difference was statistically significant (P<0.05).ConclusionThe clinical application of seven sevoflurane anesthesia for elderly patients with coronary heart disease during propofol is feasible, but seven halothane on blood pressure and heart rate of patients affected with propofol, improve the myocardial enzyme level, and better reduce the damage of perioperative myocardial, more suitable for anesthesia in elderly coronary heart disease.

Objective:To explore the effect of TSPG (total saponins of panax ginseng) on gene expression of IL-3 which is one of the important hematopoietic growth factor at early stage of hematopoiesis.Methods:Techniques of RT-PCR and in situ hybridization were used.Results:A band corresponding to IL-3 was observed after RNA extraction from TSPG stimulated Jurkat cells were subjected to RT-PCR,while such band was not observed after RNA extraction from unstimulated Jurkat cells were subjected to RT-PCR.Comparing with the control group,both quantity and intensity of IL-3mRNA expression in fetus thymocytes and splenocytes induced by TSPG were obviously promoted.Conclusion:TSPG can induce human lymphocytes to express IL-3 mRNA,thus promote human hematopoiesis at early stage.

Objective:To establish a stable and effective system of mouse embryonic fibroblasts(MEFs) feeder layer in order to separate and culture mouse embryonic stem cells(ESC) in vitro.Methods:the MEFs were isolated from the mouse embryos at 13.5~14.5dpc(days post-coitus) through primary tissue digestion and tissue piece culture.The optional planting density of cell was determined according to the cellular growth curve detected by MTT and the morphology in the culture dish under inverted microscope.The optional concentration of mitomycin C and the time treating with mitomycin on MEFs were determined by MTT assay.Murine blastcysts(3.5dpc) were cultured on the feeder layer treated by mitomycin C and ESC growth was observed.Result:The method of tissue digestion and tissue piece culture is an efficient way to obtain primary MEFs;1?105~2?105/ml cells is an optional planting density;MEFs proliferation could be effeciently repressed after being treated with mitomycin C 10?g/ml for 3.5 hours or 20?g/ml for 2.5 hours,and the quantity of MEFs could maintain at least for 7 days.ES clone could be obtained from the mouse blastcysts(3.5dpc) after being cultured on the feeder layer.Conclusion:MEFs feeder layer could effectively support mouse embryonic stem cells to grow.

Objective Panax ginseng is a well-known Chinese traditional medicine functional in “invigorating qi”,and saponins are one of its main effective fractions.Our study investigates the effect of total saponins of panax ginseng(TSPG)on human hematopoiesis at early stage and its possible regulative mechanism to clarify the hematonic mechanism of Panax ginseng. Methods The techniques of culturing hematopoietic progenitor cells in vitro,bioassay of hematopoietic growth factor(HGF),immunocytochemistry and nucleic acid in situ hybridization were used to study the effect of TSPG on IL-3’s expression in hematopoietic stromal cell and its possible mechanism. Results TSPG directly added into culture system in vitro can markedly increase the colony forming yields of CFU-Mix;the different conditioned culture media prepared with TSPG can promote the proliferation and differentiation of CFU-Mix;the protein and mRNA expression of IL-3 in BMSC and cells of EcV304,THP induced by TSPG has been much intensified.Conclusion TSPG may regulate hematopoiesis at early stage by activating IL-3's gene expression in hematopoietic stromal cell,which is the most important element in hematopietic inductive microenvironment(HIM).

Cadherins that mediate the adhesion of the same type of cells by specific binding to calciumdependent adhesions of the same type with cadherins mainly consist of three subtypes including E-cadberin,P-cadherin and N-cadherin.In recent years,more and more studies have indicated that cadherins are closely related to triple-negative breast cancer(TNBC)and play an important role in prognosis and treatment of TNBC.

Skin toxicities are the most common adverse effects of epidermal growth factor receptor inhibitors(EGFRI).It can result in significant physical and psyehological discomfort,and even leads to interruption or dose modification,and consequently affect the curative effect. Nowadays this adverse effect has attracted lot of attention.It is proposed that clinical management and treatment measures for skin toxicities should be further studied to improve the patients life quality,and guarantee the continuity and best curative effect of the treatment.But more researches on the pathogenesis and its prognostic significance are still expected.

The hereditary diffuse gastric cancer (HDGC) is associated with CDHI (E-cadherin gene)germline mutations, and accounts for about one-third of the familial gastric cancer (FGC) cases. The other two thirds FGC cases which are not fit the diagnosis standard of HDGC remain lack of clear molecular diagnosis basis. The current disposal of prophylactic gastrectomy in FGC according to E-cadherins genetic counseling, has clinical significance only in part of HDGC.

Objective To improve the awareness of rare mixed prostatic carcinoma. Methods We reviewed the clinical data of 5 patients with prostatic mixed tumor and relevant literature to ex-plore diagnosis and treatment for it. Results Patient 1 with mixed small cell carcinoma and adeno-carcinoma of the prostate who underwent transurethral electrovaporization of the prostate (TUVP) and flumamide therapy died of lung metastasis 7 months later. Patient 2 with mixed small cell carcinoma and adenocarcinoma of the prostate who underwent TUVP and bilateral testicular resection died of lung metastasis 10 months later. Patient 3 with adenosquamous carcinoma of the prostate who underwent TUVP, radiation therapy and flumamide therapy died of multiple organ failure 8 months later because of the lung, liver, and multiple bone metastasis. Patient 4 with prostatic adenosquamous carcinoma who underwent cystoprostatectomy combined with urinary diversion has already survived for 1 year. Patient 5 with prostatic carcinosarcoma who underwent cystoprostatectomy, urinary diversion, pelvic lymphadenectomy, and radiation therapy died of lung metastasis 13 months later. Conclusion Mixed prostatic carcinoma is quite aggressive with bad prognosis. Its diagnosis relies on detailed pathological examination and immunohistochemical techniques. Patients with prostate adenocarcinoma should be followed up timely after endocrine treatment or radiotherapy. Radical surgery is most effective for mixed prostatic carcinoma.
