Type 1 diabetes mellitus and autoimmune thyroid disorders are the most common combination of autoimmune polyendocrine syndrome type Ⅲ(APS Ⅲ). However, APS Ⅲ combined with myasthenia gravis is rare. We described a male patient with myasthenia gravis, type 1 diabetes mellitus, and Hashimoto thyroiditis, who was diagnosed as APS Ⅲ. The human leukocyte antigen (HLA)type was analyzed in this patient. We subsequently reviewed 11 cases of APS Ⅲ combined with myasthenia gravis. This review revealed that HLA-DR9/DQ9 might be a specific HLA subtype associated with APS Ⅲ and complicated with myasthenia gravis .

Objective The aim of this study is to evaluate the efficacy and safety of preoperative Computed Tomography (CT)-guided microcoil localization for pulmonary ground-glass opacity.Methods We performed CT-guided Microcoil localization in 30 patients with 32 pure ground glass opacities between December 2012 and September 2013.All 30 patients underwent CT-guided micmcoil localization under local anesthesia with a 21G needle percutaneous lung biopsy.All patients accepted video-assisted thoracic surgery after the localization the same day or the next day.Results We located 32 pure ground glass opacitiesin 30 patients.The mean lesion diameter was 0.94 cm,the average depth from the visceral pleura was 0.71 cm,all leisons were successfully located by microcoil,asymptomatic pneumothorax was observed in seven patients,pulmonary hematoma was observed in two patients,pain was observed in one patient,dislodgement was found in one patient during the operation.None of these cases needed surgical treatment.Pathologic diagnoses of the target leisions were as follows:adenocarcinoma in situ (n =17),adenocarcinoma(n =9),atypical hyperplasia(n =4),inflammation (n =2).After the placement of preoperative CT-guided microcoil localization for pulmonary ground-glass opacity,all the 32 pulmonary pure ground-glass opacities resection success rate was 100％.Conclusion Preoperative CT-guided microcoil localization for pulmonary pure ground-glass opacity is a safe and effective way to improve the accuracy of surgical resection.

Objective To investigate the clinical value of the gated blood pool imaging phase analysis method in the evaluation of left ventricular mechanical synchronization in patients with chronic heart failure. Methods A total of 169 patients with chronic heart failure were enrolled in our study , using gated blood pool imaging phase analysis method to obtain left ventricular phase angle width ( PHB) and left ventricular phase angle standard deviation ( PSD) as evaluating left ventricular mechanical synchrony index; using tissue Doppler imaging (TDI) measurement of the standard deviation of systolic peak time(Ts-SD) of each segment by using the current prevailing 12 non-apical segments analysis method as evaluating left ventricular mechanical synchrony index, and parameters derived from both methods were compared. Results LVPHB was highly correlated with Ts-SD (r = 0. 83 ,P = 0. 000 ) . LVPSD was modestly correlated with Ts-SD ( r - 0. 69, P = 0. 000) . The ejection fraction measured by echocardiography was (42.93 ± 14. 89) % ,which was significantly higher than that measured by ERNA (39. 76 ± 17. 89)% (P <0. 01). Conclusions The evaluation of left ventricular mechanical synchrony in patients with chronic heart failure by the gated blood pool imaging can provide similar information with TDI, which can simultaneously measure two ventricular functions and get more accurate measurement of ejection fraction. Cardiac resynchronization therapy patients can be identified by combining two kinds of approaches, and cardiac resynchronization therapy responders could be improved as well. More patients with heart failure can benefit from cardiac resynchronization therapy therapy.

Objective To retrospectively investigate the incidence of accidental awareness during general anesthesia in selective operation and analyze the influence factors of accidental aware-ness.Methods Patients scheduled for elective surgery requiring general anesthesia with artificial air-way during April 2013-July 2015 were collected.The incidence was obtained from postoperative fol-low-ups.Perioperative data and anesthetic drugs were collected to analyze influence factors. Results A total of 141 294 patients were enrolled.Eighty patients (0.06%)were definitely identified as awareness.Multiple regression analysis showed that awareness during operation was associated with total intravenous anesthesia (OR=5.181,95% CI 3.032-8.853),using laryngeal mask airway (OR=2.478,95% CI 1.544-3.977)and ASA Ⅲ or Ⅳ (OR=9.202,95% CI 5.475-15.466).Pre-medication of midazolam (OR=0.125,95% CI 0.080-0.196)and combination of sevoflurane (OR=0.193,95% CI 0.113-0.330)had lower incidence of awareness during operation.Conclusion Total intravenous anesthesia,using laryngeal mask airway and ASA Ⅲ or Ⅳ are risk factors of accidental awareness during general anesthesia.Premedication of midazolam and combination of sevoflurane may prevent awareness during operation.

AIM:Toinvestigatetheeffectsofcalcitoningene-relatedpeptide(CGRP)onmyocardinexpres-sion and phenotypic switch in vascular smooth muscle cells ( VSMCs) .METHODS:VSMCs were obtained by aortic tissue adherent culture and treated with angiotensin Ⅱ( AngⅡ) , AngⅡ+CGRP or AngⅡ+CGRP +CGRP8-37 .The protein expression of myocardin and the phenotypic proteins of the VSMCs was detected by Western blot .RESULTS:The expres-sion of myocardin in cultured VSMCs showed downregulation along with time expansion .The protein level of myocardin was higher at 48 h and 72 h than that at baseline in the cultured VSMCs (P<0.05).However, the myocardin was lower at 48 h and 72 h than that at baseline after treatment with CGRP in cultured VSMCs (P<0.05).Furthermore, at 48 h in cul-tured VSMCs, the myocardin decreased along with α-smooth muscle actin (α-SMA) (P<0.05), and osteopontin (OPN) increased (P<0.05) in AngⅡ group compared with control group .After treatment with CGRP, the levels of myocardin andα-SMA become higher ( P <0.05 ) but OPN was lower ( P <0.05 ) in CGRP group than those in AngⅡ group. CGRP8-37 abrogated CGRP-induced increase in myocardin and α-SMA and decrease in OPN in CGRP 8-37 group compared with CGRP group .CONCLUSION: CGRP may regulate the phenotypic switch of the VSMCs and maintain the cells in contractile phenotype through the upregulation of myocardin protein , which may be accomplished by the combination of CGRP and its receptor .

Objective To prospectively evaluate the efficacy and safety of Computed Tomography (CT)-guided microcoil localization for pulmonary small solid nodules and ground-glass opacity prior to thoracoscopic resection.And to investigate the indication for CT-guided microcoil localization for small solid pulmonary nodules and ground-glass opacity.Methods From December 2012 to February 2014,85 enrolled patients with pulmonary solid nodules and ground-glass opacity underwent CT guided microcoil localization prior to video assisted thoracoscopic surgery.The procedures of localization were performed by trailing method or routine method under CT guided percutaneous pneumocentesis.For Trailing method,the microcoil was placed with the distal part coiled adjacent to the lesion and the proximal end coiled beyond the parietal pleura.By routine method,the entire microcoil was injected adjacent to the lesion.Results CT-guided microcoil placements were successful in all ninety-one lesions,including 15 solid nodules,15 mixed ground glass opacity,and 61 pure ground glass opacity,with an average diameter of 8.75mm(5-26 mm).The Complication rate of the localization procedure was 23.5％ (20/91),with 13 cases of asymptomatic pneumothorax,and 7 cases of pulmonary hematoma.None patient required surgical intervention,nor severe Complication occurred.All patients underwent video assisted thorascopic surgery on the same day or the next few days after microcoil localization.VATS removal of the pulmonary lesions was successful in all patients.However,two of 91 microcoils were found displaced during VATS resection.The success rate of microcoil marking VATS resection for pulmonary small solid nodules and ground-glass opacity was 97.8％.Microcoil marking was required for 84.6 percent of all the resected lesions.Conclusion Preoperatively CT-guided microcoil localization for pulmonary small solid nodules and ground-glass opacity is a feasible safe and effective marking technique for video assisted thoracoscopic resection.The indication for microcoil localization in our study meet the requirement of VATS resection.

To investigate the prognostic effects of integrated traditional Chinese and Western medicine therapy without antibiotics in treatment of patients with severe acute pancreatitis (SAP).

Osteoporosis is a systemic skeletal disease that causes a huge medical burden on patients and society. Drug treatment is the main intervention for anti-osteoporosis, but objectively existing adverse reactions reduce the patient's compliance and affect the effect of medication. Traditional Chinese medicine has good curative effect and safety in the prevention and treatment of osteoporosis, but its mechanism of action needs to be further studied. The pathway regulates the progress of osteoporosis and is one of the main targets for osteoporosis pathological mechanism and pharmacological research. In recent years, an increasing number of studies have been made on the regulatory mechanism of osteoporosis signaling pathways by active ingredients of Chinese materia medica. Recent research results on the active components of Chinese materia medica interfering with biological signaling pathways was reviewed in this article, in order to provide ideas for new drug development, basic research, and clinical applications for osteoporosis.

Objective To establish the radiolabeling method for peptide K237 with 131I and investigate the biodistribution and therapeutic efficacy of 131I-K237 on nude mice bearing human lung cancer.Methods Iodogen method was used for labeling K237. The bioactivity of 131I-K237 was tested by human umbilical vein endothelial cell ( HUVEC ) proliferation inhibitory assay and the affinity of 131I-K237 was examined by competition binding studies. Twenty-five mice were divided into five groups randomly, including physiologic saline (group 1), K237 (40 μg) (group 2), 131I ( 11. 1 MBq) (group 3), 131I-K237 (K237 40 μg, 11. 1 MBq) intravenously ( group 4), and 131I-K237 ( K237 40 μg, 11.1 MBq) intratumorally (group 5). Injections were repeated at 15 d after the first injection. The tumor growth inhibition rate was calculated. Student's t-test and analysis of variance (ANOVA) were used for testing significant differences of data. Results The inhibition rate of HUVEC proliferation had no significant difference between radiolabeled K237 and unlabeled K237 ( (73.69 ± 5.36) % vs ( 62.68 ± 3.83 ) %, t = 1.67, P ＞ 0.05 ). The growth of transplanted lung cancer was inhibited by 75. 01 % in group 4, 78.99% in group 5, 31.15% in group 2 and 12.61% in group 3, respectively. The average tumor volume of groups 4 and 5 were significantly smaller than that of groups 1,2, and 3 ( F = 15. 233 and 13.611, respectively, P ＜0. 01 ). Conclusion 131I-K237 can be readily radiolabeled and it can effectively inhibit the growth of tumor in nude mice bearing human lung cancer.
