Objective To investigate the effects of compound danshen dripping pill (CDDP) on carotid intima￣media thickness (CIMT) and cardiac function in patients newly diagnosed as hypothyroidism. Methods The total of 40 subclinical hypothyroidism patients and 40 hypothyroidism cases was enrolled.The clinical hypothyroidism patients were treated with L￣T4 as the conventional treatment, and comprehensive CDDP plus levothyroxine (L￣T4 ) as treated groups (CDDP group) for 6 months. The therapeutic effect was evaluated by combining with data of thyroid function, blood lipid profile and ultrasound.The 40 healthy subjects were chosen as normal control group. Results Compared with normal control group, the levels of TC and LDL￣C were higher (P<0.05) in subclinical hypothyroidism group, which were more obvious in the clinical hypothyroidism group (P<0.01), CIMT increased markedly (P<0.05), the left ventricular systolic functions (ejection fraction) and diastolic functions (mitral flow velocity E and A wave ratio) were markedly decreased (P<0.05) in the clinical hypothyroidism group.Upon treatment, the blood￣lipids were improved (P<0.05), CIMT were reduced (P<0.05), the left ventricular functions were restored to near normal with the attainment of euthyroidism in both groups of clinical hypothyroidism;the reduction of CIMT and the improvement of the left ventricular functions were faster in CDDP group than that in the conventional treatment group (P<0.05). Conclusion Disturbance of blood lipid in hypothyroidism patients, CIMT growth and impaired left ventricular function objectively indicate the existence of cardiac and cerebral vascular risk, while CDDP helps improving lipid metabolism, reversing CIMT and cardiac function, reducing cardiovascular risk, blocking or delaying cardiovascular event chains.

AIM: To investigate the alteration and its significance of T help 17 cells(Th17) in patients with chronic lymphocytic thyroiditis(CLT). METHODS: Patients were divided into 3 groups: CLT patients with euthyroidism (n = 15), CLT patients with hypothyroidism (n = 30) and healthy control group(n = 20). The ratio of Th17 lymphocytes subpopulations in the preipheral blood were evaluated by technique of flow cytometry. Production of thyroid autoantibody (TPO-Ab, TG-Ab) were measured by electro-chemiluminescence immunoassay (ECLIA). RESULTS: Compared with the healthy control group, in CLT group: The frequencies of Th17 in peripheral blood were found to be significantly higher in patients with CLT than healthy control group (P < 0.01); Production of TPO-Ab and TG-Ab markedly increased in CLT patients than healthy control group (P < 0.01). There was significant correlation between the positive expression of thyroid autoantibody and the changes of Th17 subpopulations (r=0.50, r=0.43 respectively; P < 0.01). CONCLUSION: The frequencies of Th17 cell increased in patients with CLT which may suggest a potential role for Th17 in the progression and happen of CLT.

Succesiful operation was performed in the 3 patients without complication, the average operation time being 240 minutes, and hospitelization duration averaging 4.5 days.

Objective To explore the correlation among serum immunoglobulin G4 (IgG4),transforming growth factor-β1 (TGF-β1),connective tissue growth factor (CTGF) and Hashimoto thyroiditis (HT) thyroid fibrosis.Methods Case-control study.A total of 159 patients with HT visiting the Wuhan Union Hospital were collected from May 2013 to March 2015.All patients were divided into IgG4 HT group (IgG4≥1.35 g/L,n =39) and non-IgG4 HT group (IgG4 ＜ 1.35 g/L,n =120).The serum IgG4,TGF-β1 and CTGF were determined by enzyme-linked immunosorbent assays.The levels of serum thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibodies (TgAb) were measured by electrochemiluminescence immunoassay.Meanwhile,ultrasound of the thyroid gland was performed.Statistical analysis was performed by use of SPSS 17.0 software.The Mann-Whitney U test was used to compare two independent samples of non-normal distribution data,Fisher's exact test was employed to analyze thyroid imaging differences,correlation test was performed to examine various correlations,multivariate Logistic regression analysis was used to evaluate thyroid fibrosis risk factors.Results Compared with that of non-IgG4 HT group,IgG4 HT group:TPOAb [(455.2 ± 169.7) vs.(186.5 ± 102.3),U =27.0,P=0.003],TgAb [(984.6±452.7) vs.(289.3 ±245.1),U=30.5,P=0.017],TGF-β1 [(1.45±0.97) vs.(0.30±0.22),U=119.0,P=0.035] andCTGF [(88.65±14.39) vs.(62.21± 8.76),U =69.0,P =0.039] were significantly higher,thyroid ultrasound showed obvious fibrosis (35/4 vs.32/88,x2 =48.03,P =0.000);significant positive linear correlation between IgG4 and TPOAb (r =0.719,P =0.000),CTGF and TGF-β1 (r =0.500,P ＜ 0.01) respectively.Logistic regression analysis indicated that all the serum IgG4,TPOAb,TGF-β1 and CTGF were independent risk factors of thyroid fibrosis [IgG4,odds ratio (OR) =1.968,P =0.014,95％ confidence interval (CI) =1.287-2.041;TPOAb,OR =2.537,P =0.012,CI =1.322-2.869;TGF-β1,OR =1.549,P =0.023,CI =1.105-1.498;CTGF,OR =1.185,P =0.046,CI =1.204-1.625].Conclusion The highlevel of circulating antibodies,IgG4,TGF-β1 and CTGF were significantly associated with thyroid fibrosis,and were independent risk factors of HT fibrosis.

Objective:To explore the serum IgG4 level in patients with IgG4-related Hashimoto thyroiditis(IgG4 HT),and its clinical implications.Methods:The serum IgG4 was determined in 129 patients with HT using enzyme-linked immunosorbent assays and classified into two subgroups based on IgG4 level:IgG4 HT group(IgG4≥135 mg/dl)and non-IgG4 HT group(IgG4<135 mg/dl).And the levels of serum thyroid hormone and thyroid peroxidase antibodies(TPOAb)and thyroglobulin antibodies(TgAb)were measured by electro-chemiluminescence immunoassay.Ultrasonic imaging of the thyroid gland were detected.Results:The TPOAb levels correlated significantly with both serum IgG4 levels(r=0.437 1,P=0.012 7)and IgG4/IgG ratios(r=0.396 2,P=0.023 5)in the patients with HT.Compared with that of non-IgG4 HT group(n=97),IgG4 HT group(n=32):①The mean age was lower(P=0.029 3);②Higher levels of serum TPOAb(P=0.002 1)and TgAb(P=0.012 8);③Ultrasound imaging:the more obvious thyroid nodule(P=0.022 6);④Logistic regression analysis showed that serum IgG4 and TPOAb were the risk factor for thyroid nodules(OR=1.672,P=0.021;2.549,P=0.014 ).Conclusion: IgG4 HT patients existed corresponding clinical characteristics.For the HT-patients with elevated serum IgG4,thyroid function and morphology should were more closely monitored.

Objective　To clone the partial positive regulatory fragment of Na+/H+ exchanger-1 (NHE-1) gene from human lung cancer cells. Methods　After BamHⅠ and EcoRⅠ cut sites were added to the 5' ends of the upstream and downstream primers respectively, the partial positive regulatory sequence of NHE-1 gene was cloned with the length of 170 bp from genomic DNA of lung cancer cell line A549 cells with PCR method. The cloned fragment was ligated to plasmid pUC18. Finally, the constructed recombinant was identified with enzyme cut, PCR and DNA sequencing. Results　The cloned fragment was about 170 bp in size and successfully ligated to pUC18 with identifiation of double enzyme cut and PCR. DNA sequencing approved that the fragment cloned was objective one with 168 bp in length. Compared with the reported sequence, two t were lost. Conclusion　The positive regulatory fragment of NHE-1 gene from human lung cancer cells was successfully cloned.

Objective To observe the effects of dual antiplatelet therapy at different time after cervical artery stenting and to investigate the reasonable time for dual antiplatelet therapy. Methods Sixty-six patients with symptomatic cervical artery artery stenosis ＞50% or asymptomatic stenosis ＞70% performed stenting under local anesthesia. They were randomly allocated into dual antiplatelet therapy (aspirin + clopidogrel) for 1 month and for 3-month groups after procedure, and then they began to take aspirin for a long time. The complications, vascular events, and the incidence of restenosis were observed respectively. Results There were no vascular events and death in both groups from 6 to 36 months after procedure. There was no significant difference in the incidence of complication and restenosis (9% vs. 6%, P = 0. 642). Conclusions There was no significant difference in the efficacy of aspirin + clopidogrel treatment after cervical artery stenting between 1 month and 3 months. One month dual antiplatelet therapy may be appropriate, but large-scale randomized controlled trials are needed to confirm it.
