Medullary thyroid carcinoma originates from parafollicular cells. Its prognosis is worse than that of differentiated thyroid carcinoma. Surgery is the best treatment for early stage diseases. In the past decade, dominant activating mutations in the RET pro-oncogene have been identified as the main cause of MTC. Mutation analysis of the RET proto-oncogene has been used in the early diagnosis, prophylactic surgery and targeted therapy of MTC.

At the beginning, this paper introduced the concept of merit in folk medicine simply. Secondly, the situation that although the healer cure but with no contribution is introduced to analyze the reason. Finally, it discussed the characteristics of the doctor-patient relationship based on treatment effect of Ming dynasty and realis-tic enlightenment to current doctor-patient relationship:the industry has threshold, general knowledge should be unbounded;the responsibility has expanded, merit must be clarify;rights are in the ascent, exercising right should be in accordance with the laws;the rules are very important, later supervision is also needed.

Objevtive To evaluate the efficacy and safety of intensive pulse light (IPL) on treating the telangiectasis and dermal atrophy due to corticosteroid-dependent dermatitis.Methods We applied the IPL on 13 patients who had telangiectasis and dermal atrophy caused by corticosteroid-dependent dermatitis every three to four weeks.The treatment lasted three to eight times.The patients's skin types were Fitzpatrick Ⅲ-V and they had had corticosteroid therapy from 15 months to 13 years.Results To telangiectasis,3 patients had excellent effect afterwards;7 patients achieved fair good effect;Another patients also achieved improvement;2 cases had no positive effect;The total effective rate reached 76.92%.10 patients of dermal atrophy among the total 13 had improvement of the thickness of dermis.Conclusion Intensive pulse light can improve the telangiectasis and dermal atrophy of corticosteroid-dependent dermatitis.It needs less recovery time with fewer side effects and therefore IPL is an effective method for the Iesions.

Synuclein-γ (SNCG) is overexpressed in many advanced stages cancers, including breast cancer, ovarian cancer, prostate cancer, lung cancer, liver cancer, esophagus cancer, and colon cancer.SNCG stimulates the proliferation, metastasis, and drug resistance of tumor cells, through interacting with BubR1 and damage mitotic checkpoint. A peptic ANK targeted at SNCG can inhibit activity of SNCG and may be developed as an adjuvant therapy.

Objective To investigate the risk factors for ischemic stroke in patients of Aba Tibetan and Qiang Autonomous Prefecture. Methods From March 2012 to March 2014,314 consecutive patients with ischemic stroke admitted to the Department of Neurology,Aba Tibetan and Qiang Autonomous Prefecture People′s Hospital,Sichuan Province were enrolled respectively. All patients were Tibetans. They were divided into either an observation group (n = 105)or a control group (n = 209)according to whether they had high-altitude polycythemia or not. The observation group was the patients with high-altitude polycythemia complicated with ischemic stroke,and the control group was the patients with ischemic stroke without high-altitude polycythemia. The risk factors for onset of stroke in both groups were compared,and the single factor indices with statistical significance were analyzed by multiple logistic regression analysis. Results There were significant differences in hypercholesteremia,history of heavy smoking,and family history of stroke between the observation group and the control group (χ2 values were 6. 489,8. 107,and 11. 206,respectively;P values were 0. 011,0. 004,and 0. 001,respectively). There were no significantly difference in other stroke risk factors between the 2 groups (all P > 0. 05). Multiple logistic regression analysis showed that hypercholesteremia,history of heavy smoking,and family history of stroke were the independent risk factors for high-altitude polycythemia complicated with ischemic stroke (hypercholester-emia:OR,4 . 799 ,95 % CI 1 . 266 - 3 . 148 ,P = 0 . 028;history of heavy smoking:OR,4 . 539 , 95 % CI 1. 061 -4. 182,P =0. 033;family history of stroke:OR,3. 549,95% CI 1. 279 -5. 377,P =0. 008). Conclusions Hypercholesteremia,history of heavy smoking,and family history of stroke,are the independent risk factors for ischemic stroke. The prevention of stroke in the local area should be targeted at the geograph-ical and population characteristics.
