Objective To investigate the clinical characteristics and diagnostic methods of multiple endocrine neoplasia ( MEN) 2B. Methods The clinical data collected from 4 cases with multiple endo-crine neoplasia type 2B, who had been diagnosed and treated from July .1980 to Jan.2012, were retrospec-tively analyzed.Of the 4 patients, 3 males were diagnosed at the age of 14, 24, 21, respectively, and 1 fe-male was diagnosed at age of 23.Two cases had the first diagnosis of thyroid mass during the physical exami-nation, and the adrenal tumors and hypertension were first diagnosed in other two cases , respectively.All four cases had multiple mucosal neuromata .Of whom, three cases had medullary thyroid carcinoma and pheochromocytoma , two cases had Marfan syndrome figure , and one case had pheochromocytoma and Marfan syndrome.Two cases were accompanied by paroxysmal hypertension , and the highest systolic blood pressure was over 200 mmHg (1 mmHg=0.133 KPa).Two cases of pheochromocytoma were found during follow up . Three cases had bilateral adrenal tumors .The thyroid mass was diagnosed by ultrasonography , and the pheo-chromocytoma was confirmed by ultrasonography , CT and 24-hour urine catecholamine test .Adrenalectomy and thyroidectomy were carried out during the treatment process .To clarify the RET mutation status , exons and adjacent introns from 10th to 16th of RET proto-oncogene were sequenced in two patients . Results Gene analysis of two cases confirmed the activating mutation at the sites of 918 in exon 16 of RET proto-on-cogene in which methionine was replaced by threonine ( ATG-ACG) .Among the 3 cases with medullary thy-roid carcinoma , two patients were treated by total thyroidectomy and neck lymphadenectomy , one was opera-ted by subtotal thyroidectomy .For the treatment of pheochromocytoma , adrenal tumor resection was carried out in 3 cases, but not in the other one .Patients were followed up for 2 to 15 years postoperatively , 1 case without tumor recurrence and metastasis , 2 cases with multiple metastases . Conclusions The diagnosis of multiple endocrine neoplasia type 2B mainly depends on endocrine tests , ultrasonography and CT .Surgery is the primary treatment .When pheochromocytoma coexists with other tumors , pheochromocytoma should be re-moved first .

OBJECTIVE:To explore the general regulation and characteristics of adverse drug reactions(ADR)induced by ti-cagrelor,and provide reference for clinical rational drug use. METHODS:672 patients received ticagrelor in our hospital from Dec. 2013 to Jun. 2015 were followed-up,and the situation was analyzed and summarized after taking drug. RESULTS:In the 672 patients,78(11.6%)patients sutfered from 108 cases of ADR,the ratio of male to female was 5.5∶1,there was statistical signifi-cance (P<0.05);patients mostly aged 51-60 years (37.2%);the mainly involved organs/systems were respiratory system (41.7%),and skin and its appendages (38.0%),the main clinical manifestations were minor bleeding (78.7%),dyspnea (17.6%) and bradycardia (2.8%);no severe ADR was found. CONCLUSIONS:Ticagrelor had good safety and tolerability,but due to its shorter time to market in China and absense of evidence-based medicine for large-scale clinical trials in Asian population, clinic should strengthen medication monitoring to reduce the ADR and ensure drug safety.

AIM: To explore the curative effects of various approaches to improve the arterial inflow following flap grafting with various tensions. METHODS: 135 patients with skin defects in limbs, who underwent flap grafting in Department of Orthopedics, Baoan People's Hospital of Southern Medical University between August 2002 and August 2006, were selected, and informed the consent. The wounds of every 45 cases were sutured under the tension of 1.0 kg, 1.5 kg, and 2.0 kg, respectively; meanwhile, all patients were randomly divided into hyperbaric oxygen group, dexamethasone group, and local injection of heparin group with 15 cases in each group, and given the corresponding treatment besides ordinary treatment. Seven days later, the flap survival was observed. RESULTS: 135 patients were all involved in the result analysis without any loss. The flaps of 90 patients recovered completely under the tension of 1.0 kg and 1.5 kg. But under 2.0 kg tension, the flaps of 10 penitents in the hyperbaric oxygen group recovered, 4 survived mostly and 1 necrosed; in the dexamethasone group, 5 flaps recovered, 3 survived mostly, and 7 necrosed; in the local injection of heparin group, 3 flaps recovered, 3 survived mostly, other 9 necrosed completely. CONCLUSION: The suture tension of 1.0 kg to 1.5 kg is feasible in flap grafting, and compared with heparin and dexamethasone, hyperbaric oxygen could better promote the arterial inflow under high tension like 2.0 kg.

Myocardin is a remarkably potent transcriptional coactivator which specifically expresses in cardiovascular system and directly binds to serum response factor.It activates transcription of a subset of SRF-regulated genes encoding cardiomyocytes and smooth muscle cells contractile proteins.Abnormal expression of myocardin is associated with cardiovascular diseases including atherosclerosis,myocardial hypertrophy and hypertension.Here,recent developments in the structure,expression and regulation of myocardin and its relation with cardiovascular diseases are reviewed.
