4.On the compensation mechanism for urban medical services
Chinese Journal of Hospital Administration 2009;25(5):297-301
Reform on medial service compensation mechanism,as a key point in the heahhcare system reform,runs through the entire reform process.It plays a key role for the establishment and improvement of urban medical care system,medical service system,medical management system and operating system,for its guidance and regulation effects.Such a refonn to build a scientific and perfect compensation model and mechanism will be highly significant for the smooth progress of the new round of healthcare reform and its success in the end.
5.The effect of CsA on the morphology of the liver-the stereological analysis of the hepatic ultrastructure
Chinese Journal of Organ Transplantation 2000;21(6):334-336
Objective To study the effect of CsA in a therapeutic dose on the hepatic ultrastructure in rats.Methods Twenty-four SD rats were divided into 3 groups.The control group was orally administered olive oil,and the other 2 groups were orally given CsA 25 mg/kg and 50 mg/kg daily respectively.After 2 weeks.the liver samples were taken for ultrathin sections.The stereological method was used to quantify some hepatic ultrastructural parameters including volume density (Vv),surface density(Sv),numerical density(Nv) and specific surface(δ).Results CsA caused an increases of Vv and Sv and a decrease of δ in endoplasmic reticulum;a decreases of Vv and Nv in microbody;decreases of Vv in Golgi complex and glycogen inclusions;an increases of Vv and Nv in lipid inclusions.Conclusion CsA in a therapeutic dose could cause the change of hepatic ultrastructure of rat.
6.Progress of carbon monoxide and inflammation
International Journal of Surgery 2008;35(4):257-259
Carbon monoxide(CO)has a significant anti-inflammatory action.Carbon monoxide releasing molecule(CORM),as a new donor of CO,is used widely in biological study.The article reviewed the antiinflammatory action of CO and the progress of CORM.
7.Radiotherapy in the treatment of uterine sarcomas
Chinese Journal of Obstetrics and Gynecology 2001;36(3):159-161
Objective To study radiotherapy in the treatment of uterine sarcomas and response to radiation in primary or recurrent uterine sarcomas. Methods A total of 102 uterine sarcomas treated in the Cancer Hospital from May 1960 to June 1999. A retrospective review of 45 patients receiving surgery alone, 29 patients for postoperative radiotherapy, 4 radiotherapy alone, 24 recurrent sarcomas receiving radiotherapy. Results The 5-year overall survival for 45 patients treated with surgery alone and 29 patients managed by postoperative radiotherapy were 56.7% and 58.6% respectively (P>0.05). The addition of radiotherapy significantly reduced the local recurrence rate from 42.2% to 20.7% (P<0.05). The tumor was disappeared completely by treatment of radiotherapy alone in 3 patients of primary uterine cervix sarcomas. 1 patient was free of disease at 36 months. Other 2 patients died 9 and 11 months later because of distant metastases. The complete and partial response rate of radiotherapy was 50.0% for recurrent tumors. The radiotherapetic sensibility of endometrial stromal sarcomas, mixed mesodermal sarcomas and leiomyosarcomas was downward tendency in turn.Couclusions The postoperation adjuvant radiotherapy reduced the pelvic recurrent significantly. Radiotherapy should be used in the treatment of uterine sarcomas as an important part of combination therapy.
8.Preparation of transferrin and RGD co-modified PLGA nanoparticles and its targeting to melanoma
Chinese Journal of Biochemical Pharmaceutics 2014;37(4):19-21
Objective To prepare transferrin and Arg-Gly-Asp polypeptide co-modified nanoparticles(TF/RGD-NPs)and evaluate its targeting efficiency to melanoma.Methods The co-modified nanoparticles were prepared by emulsion method and its appearance,particle size and Zeta potential were evaluated.The cellular uptake experiment and melanoma tumor spheroids penetration test were used to evaluate the affinity and ability to penetrate tumor tissues of TF/RGD-NPs to melanoma B16 cells. Results The particle diameter of co-modified nanoparticles was(113.4 ±12.5)nm and the Zeta potential was(4.53 ±2.15)mV.In vitro uptake test demonstrated that the efficacy of cellular uptaken TF/RGD-NPs by B16 cells were 2.7 times and 2.9 times to TF-NPs and RGD-NPs,respectively,the differences were all significant(P<0.05 ).Tumor spheroid penetration test results showed that TF/RGD-NPs has good affinity to melanoma cells.Conclusion TF/RGD-NPs can target to melanoma B16 cell efficiency in vitro,it may be serve as a potential drug delivery system for targeting melanoma.
9.Exploration of personnel training mode in local medical and health vocational colleges under the guidance of modern occupation education ideas
Chinese Journal of Medical Education Research 2012;11(3):236-238
Taking the modern occupation education concept as the guide,oriented by adapting to the demand of occupation post,we established a new open education mechanism of medical occupation education to promote the reform of personnel training mode,curriculum and teaching content to explore the effective way of the sustainable development of local medical occupation education.
10.Transient receptor potential channels 6 in tumor
Journal of International Oncology 2011;38(9):656-659
Transient receptor potential (TRP) is a kind of novel Ca2+ permeant channel.It is later found that TRP channels are expressed broadly in many organisms,tissues and cell types.It is involved in the regulation of sensory conduction and cell signal transduction.Further studies are required to assess which TRPC6(a member of TRPC subfamily) is associated with the cytosolic Ca2+ levels,development and progression of cancer and tumor cell cycle.TRPC6 may be regarded as new targets for the treatment of cancer.
