RESUMEN
OBJECTIVE： To study the inhibitory effect of modified Maimendong decoction combined with cisplatin on Lewis lung cancer transplantation model mice， and to explore its potential mechanism. METHODS： Lewis lung cancer transplantation mice model was induced via subaxillary inoculation of Lewis lung cancer cells. 60 mice were randomly divided into model group （normal saline， once a day， i.g.）， cisplatin group （6 mg/kg， once a week， i.p.）， modified Maimendong decoction group （20 g/kg. once a day， i.g.） and combination group （cisplatin 6 mg/kg， once a week， i.p.+modified Maimengdong decoction， once a day， i.g.）， with 15 mice in each group. All mice were treated for consecutive 2 weeks. After medication， tumor weight and thymus index were detected； HE staining was used to observe the pathological change of tumor tissue. TUNEL was used to detect apoptotic index of tumor tissue. The protein expressions of Bcl-2 and Bax were detected by Western blot assay. RESULTS： Compared with model group， tumor weight and protein expression of Bcl-2 were decreased significantly in modified Maimengdong decoction， cisplatin group and combination group （P＜0.05）， and thymus index， tumor apoptotic index and the protein expression of Bax were increased significantly （P＜0.05）. Tumor weight and protein expression of Bcl-2 in combination group were significantly lower than modified Maimengdong decoction group and cisplatin group （P＜0.05）； thymus index， tumor apoptotic index and the protein expression of Bax were significantly higher than addition and subtraction of modified Maimengdong decoction group and cisplatin group （P＜0.05）. HE staining showed that the density of tumor cells was decreased to certain degree in modified Maimengdong decoction group， cisplatin group and combination group； the area of necrosis area in the combination group was significantly larger than in modified Maimendong decoction group and cisplatin group. CONCLUSIONS： Modified Maimendong decoction can inhibit the growth of Lewis lung cancer transplanted tumor in mice by down-regulating the protein expression of Bcl-2 and up-regulating the protein expression of Bax.
RESUMEN
Such management theories as social exchange, equity and incentives are called into play to probe, from an array of perspectives, into the functionality and role of the employee orientation in people-oriented concept as it is used in contemporary hospital management. The paper also analyzed the dialectical relationship between the concept of "employee-orientation" and that of "patients or customers orientation", and the dialectical relationship between "people-orientation" model and "policy-orientation" model It pinpoints the mistake of overemphasizing "patients or customer orientation" and neglecting employee management in hospital management, proposing a people-oriented path centering on employees in hospital management.
RESUMEN
OBJECTIVE:To prepare Xielong liquor and establish its quality control.METHODS:Xielong liquor was prepared by classic merceration.Paeonia lactiflora in the formulation was identified by TLC,and the content of the active component ferulaic acid was determined by HPLC.RESULTS:The preparation was yellowish-brown in color and its TLC spots were clear and well-isolated.The linear range of ferulaic acid was 3.66～36.64 mg?L-1(r=0.999 8)and its the average recovery was 100.47%(RSD=0.84%,n=15).CONCLUSION:The preparation technology of Xielong liquor is simple and feasible and the quality of the preparation is stable and controllable,thus the established standard is applicable for the quality control of Xielong Liquor.
