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 .

3. Research progress on mechanism of active components of Chinese materia medica in treatment of osteoporosis based on signaling pathway
Chinese Traditional and Herbal Drugs 2020;51(23):6084-6094
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.

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 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 explore the correlation between anti-cyclic citrullinated peptide(A-CCP) antibody and tumor necrosis factor(TNF)-?, rheumatoid factor(RF), ESR, PLT count and clinical features in patients with rheumatoid arthritis(RA), and the outcome of unclassified arthritis(arthralgia)patients after six months follow up. The value of A-CCP antibdy in the diagnosis of early RA and its pathogenetic roles is in- vestigated. Methods A-CCP antibody and TNF-?were detected by ELISA and the RF was tested by the rate scatting immunity method in 91 RA patients, 46 unclassified arthritis(arthralgia)patients and 45 other rheumatic diseases patients. Results A-CCP antibody levels in serum correlated significantly with TNF-?levels, PLT count and the degree of joint swelling in RA and unclassified arthritis(arthralgia)patients(r= 0.854, P=0.O00; r=0.882, P=0.000; r=0.318, P=0.002; r=0.486, P=0.001; r=0.291, P=0.005; r=0.731, P= 0.000 respectively). A-CCP antibody levels in serum was weakly negatively correlated with the gripping power in RA patients(r=0.228, P=0.030). And it was weakly correlated with ESR in unclassified arthritis(arthrai- gia)patients(r=0.365, P=0.013). Compared with other rheumatic diseases patients, A-CCP antibody levlels in serum increased significantly in RA and unclassified arthritis(arthralgia)patients(P=0.000). Compared with normal controls, it increased in other rheumatic diseases patients(P=0.011). Twenty-four patients had positive A-CCP antibody in 46 unclassified arthritis(arthralgia)patients. Thirty-two out of 46 unclassified arthritis(arthralgia)patients were early RA after 6 monthes follow up. 95.8%(23/24)unclassified arthritis (arthralgia)patients with positive A-CCP antibody were early RA. Conclusion A-CCP antibody reflects disease activity in certain extent. It's benefit to the diagnosis of early RA. High A-CCPantibody levels com- bined with high levels of TNF-?, ESR, PLT count and joint swelling can help the diagnosis of early RA.

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.
