1.The clinical status research on the integrated Chinese medicine and western medicine
Chinese Journal of Primary Medicine and Pharmacy 2017;24(1):142-145
Integrative medicine is the effective combination of dual diagnosis of Chinese medicine and western medicine.The combination can broaden the scope of clinical diagnosis and combine the local pathological changes with the overall response of the human disease.It can add a more comprehensive understanding of diseases for people.Clinically treated with combination of Chinese medicine and western medicine can achieve the complement of advantages.It is significant.Because the theory system of Chinese medicine compared with western medicine is different and the theory system of combination is not practical and standardized.The methods of clinical diagnosis and treatment are also different.So there are still some problems and deficiencies in the integrative medicine.In this study,through extensive literature research,as well as the clinical investigation in some integrative medicine hospitals and the collection of related clinical data,we compared and analyzed the academic ideas and different features of Chinese medicine and western medicine,analysed the status and the insufficience of current clinical integrative medicine.Finally,we put forward a series of effective strategies and methods for how to combine with integrative medicine in a specific,reasonable and effective way.

Objective:To investigate the effect and the related mechanism of c-Myc on the proliferation,invasion and migration ability of malignant melanoma B16-F10 cells. Methods:We detected the expression of PIK3R3 in malignant melanoma and normal tis-sues. Efficiency of gene silencing of c-Myc and PIK3R3 was determined by qPCR and Western blot. We detected the proliferate ability of B16-F10 cells after silencing c-Myc and PIK3R3 using EdU assay. We detected the migration and invasion ability of B16-F10 cells after silencing c-Myc and PIK3R3 using wound healing assays and Transwell matrigel invasion assays. The expression of miR-199a after silencing c-Myc and PIK3R3 using qPCR. The expression of c-Myc and PIK3R3 was detected by qPCR after transfecting miR-199a mimics or miR-199a inhibitor. Dual-luciferase reporter assay system was used to detect miR-199a regulating c-Myc and PIK3R3. Results:Compared normal skin tissue,expression of PIK3R3 was significantly increased in malignant melanoma tissue;after silencing c-Myc and PIK3R3 gene,the proliferation,invasion and metastasis of melanoma cell line B16-F10 were significantly reduced;expression of miR-199a upregulated after silencing c-Myc and PIK3R3 genes, expression of c-Myc and PIK3R3 decreased after transfecting miR-199a mimics, expression of c-Myc and PIK3R3 upregulated after transfecting miR-199a inhibitor, dual luciferase reporter system test results revealed miR-199a can directly regulate c-Myc and PIK3R3 transcription activity. Conclusion: miR199a regulated the expression of c-Myc,then promote proliferation,migration and invasion in malignant melanoma cells.

Objective To explore surgical techniques and curative effects of microsurgical treatment for tumors in upper cervical spinal canal.Methods A total of 81 cases of tumors in upper cervical spinal canal had received microneurosurgery from January 1990 to December 2005.The operation was conducted through a posteromedial approach.A total tumor resection was performed in 73 cases of neurofibroma or neurilemmoma,3 cases of spinal meningioma,and 3 cases of ependymoma.A subtotal tumor resection was conducted in 2 cases of astrocytoma.Results A complete recovery was achieved in 75 cases,an improvement of symptoms was achieved in 4 cases,and no improvement in 2.No death was encountered.Follow-up observations were carried out in 52 cases for 3 months ~ 3 years(8.5?1.5 months).MRI examinations 3 months after operation in 15 cases found no residual or recurrent tumor.X-ray radiography under anteroposterior,lateral,and open-mouth view 6 months after operation in 32 cases showed no spinal deformation and good vertebral stability.Recurrence of intramedullary tumor was seen in 3 cases. Conclusions As long as tumors in upper cervical spinal canal are diagnosed,a microsurgical treatment should be given as early as possible.Appropriate selection of surgical approach,skillful microsurgical techniques in accordance with pathological types of lesions,and principles of minimal invasion are critical for the operation safety.

AIM: To study the effect and mechanism of all-trans retinoic acid (atRA) on neural stem cell (NSCs) proliferation and differentiation from new born Sprague- Dawley rat striatum. METHODS: NSCs were isolated from the brains of new born Sprague-Dawley rat striatum, and the features of cells were characterized by immunofluorescence staining. The effects of different culture medium on cell cycle distribution and proliferation of NSCs were determined by flow cytometry (FCM) . The effects of atRA on differentiation of NSCs were determined by immunofluorescence staining and classified count of differentiated cells. RESULTS: FCM assay indicated that atRA inhibited the proliferation of NSCs. The percentage of cells in G0/G1 phase in atRA treatment group was significantly higher than that in control, and the proliferation index (PI) was significantly low. The percentage of neurons differentiated from NSCs in atRA group was 2.5 times of the control group after induced by adding 10% FCS in culture medium. CONCLUSION: atRA counteracts the effects of bFGF on the promotion of mitosis and inhibition of differentiation of NSCs. atRA also promotes NSCs to differentiate into neurons in vitro.

Objective To investigate the effect of photodynamic therapy with chlorin e6 (Ce6) and 5-aminolevulinic acid (5-ALA) on mouse model of malignant melanoma. Methods The mouse model of malignant melanoma was established by injecting 0.1 ml A-375 cells (about 2?10 6 cells) under the right hind leg of BALB/c-6 mice,and that the yellowish white node appears at injection site proves the successful model. Twenty-four of 27 successful mouse models were irradiated at the tumor site with semiconductor laser (wavelength 652 nm) with a total dose of 100 J/cm 2 . Before laser exposure,the mice were treated with 10% 5-ALA by topical compress for 2 h or 7.5 mg/kg Ce6 by intraperitoneal injection for 1 hour or 5-ALA topical application combined with intraperitoneal injection of Ce6 (n=6 in each group). Another six mice as control only underwent PDT. One week after PDT,the mice were killed,the tumor mass was peeled off and weighed,whether the metastasis occurred or not was detected,and the tumor,liver,spleen,lung,kidney were sent to histopathological examination. Results The tumor weight in 5-ALA group,Ce6 group,and the combined group had significant difference as compared with control group (P0.05). The dehydration and scab formation and necrosis could be seen in tumor sites at 1 week after PDT. The cell collapse and necrosis,subdermal thrombosis and cell outline clouding could be observed by histopathological examination. Metastasis of melanoma were found in 5-ALA group,Ce6 group,and the combined group. Conclusion PDT with Ce6 and 5-ALA could kill the malignant melanoma effectively in animal experiment but could not affect the metastasis of melanoma.
