Objective To observe the effect of the Chinese medicine on the patients’ thyroid autoantibodies TPOAb and TGAb of Hashimoto's thyroiditis. Methods 100 cases of Hashimoto's thyroiditis were randomly divided into group A and group B, with 50 cases in each group. Group A was given levothyroxine sodium(L-T4) to maintain thyroid function(FT3,FT4,TSH)in the normal range, at the same time Chinese medicines of soothing liver and strengthening spleen, nourishing the liver and kidney, activating blood and removing blood stasis were additionally added;while group B was taken L-T4 to maintain the thyroid function in the normal range. The levels of TPOAb, TGAb were determined before and after treatment in both groups. Results After the treatment, the level of TGAb and TPOAb[respectively(106.3±29.5)IU/ml,(871.5± 209.3)IU/ml] in group A were decreased compared with their previous level [respectively(385.5±76.6)IU/ml, (1621.5±399.2)IU/ml], the difference was statistically significant(t were 48.2、10.6,P<0.01). The level of TGAb and TPOAb [respectively(437.6±135.4)IU/ml,(1798.6±434.6)IU/ml] in group B were slightly increase than their previous level[respectively(383.9±105.8)IU/ml,(1633.2±396.5)IU/ml], with no significant difference. The levels of TPOAb and TGAb in group A had significant difference than those in group B after the treatment(t were 22.3、19.6,P<0.01). Conclusion TCM combined with L-T4 can reduce the level of thyroid autoantibodies of TPOAb and TGAb-in patients.

Objective To investigate the value of acoustic radiation force impulse (ARFI) on evaluating the renal tubular atrophy and interstitial fibrosis of IgA nephropathy(IgAN).Methods 117 patients diagnosed with IgAN,and 80 normal cases were examined with conventional ultrasonography and ARFI,recording the shear wave velocities(SWV),the hemodynamics and the renal biopsy results to quantify the elastic changes of renal cortex,with the aim of assessing AFRI's advantages on early diagnosing the impair of kidney.Results The SWV value of renal cortex,renal medulla of IgAN group were smaller than that of normal group (P ＜0.05),while the collective system SWV value had no difference(P ＞0.05).According to the ROC curve,the cut-off value of SWV in renal cortex was 2.7 cm/s.The accuracy of the diagnosis was 71 ％,which was better than RI (61.9％).The SWV value of the renal cortex decreased with the different stage of 1,2,3,4,but stage 5 was larger than stage 4.The degree of renal tubular atrophy and interstitial fibrosis(T) can be classified by the SWV of renal cortex,and the SWV of T2 was larger than T1 (P ＜0.05).Conclusions By quantifying the elastic change of kidney,ARFI technology is able to distinguish the degree of renal tubular atrophy and interstitial fibrosis,diagnose renal impairment early and judge the clinical stages.Furthermore the sensitivity,specificity,accuracy of it are superior to hemodynamic.

The expression of TF-1 cell apoptosis-related gene 19 (TFAR19), a novel apoptosis-related protein, in the thyroid tissues of Hashimoto′s thyroiditis (HT) was investigated. TFAR19 expression was barely detectable in normal thyroid tissues, whereas positive expression was found in the thyrocytes of HT patients. The results suggested that the activation of TFAR19 apoptosis pathway may play an important role in the pathogenesis of HT.

Objectives:To study the effect of Basen on the sensitivity of insulin in diabetes mellitus.Methods:Blood glucose,lipoprotein,insulin,C-peptide were assayed after and before the administration of Basen.Results:Levels of insulin,blood glucose,and C-peptide were lowered after four weeks administration of Basen,which changed contrarily to ISI.Conclusions:Basen has effects not only on lowering blood glucose but also on improving the insulin resistance.

Objective To explore a new surgical treatment for severe inverted nipple and to reduce the possibility of recurrence. Methods Two opposite long six-side polygon de-epithelialized areas were designed within the range of areola on both sides of the nipple. The four sides in lateral portion were dissected and two wedge-shaped dermal and glandular tissue flaps were created, completely releasing the contractive fiber causing nipple retraction while reserving breast ducts. The flaps were reversed 180 degrees through the tunnel bilateral sides of breast ducts to support the nipple. It was tracted for 3-4 weeks by series 7 needle penetrating the nipple basis. Results All the 14 patients were followed up for 3-18 months, and they were satisfied with the appearance and the aesthesia of the nipple and no recurrence was observed, breast-feed function reserved in 2 cases after childbirth. Conclusions This operation is easy to perform with satisfying aesthetic outcome and breast-feed function remaining.It is an ideal method for correcting serious inverted nipple.

Objective To investigate the effects of autoantibodies (β1-AA) against second extra-cellular loop of the β1-adrenergic receptor (β1-AR-ECⅡ) in sera of patients with dilated cardiomyopathy (DCM) on proliferation of rat CD4+T lymphocytes.Methods β1-AA in the sera of patients with DCM was purified by affinity chromatography .CD4+T lymphocytes were isolated by immunomagnetic microbeads from peripheral blood mononuclear cells of rats and its positive rate was detected by flow cytometry .CCK-8 meth-od was used to detect the proliferation of CD 4+T lymphocytes and flow cytometry was performed to measure the ratio of CD4+/CD8+T lymphocyte .Results The purity of isolated rat CD 4+T lymphocytes by immu-nomagnetic microbeads reached 97.7%.The proliferation of CD4+T lymphocytes stimulated by CD3/CD28 was inhibited by β1-AA in a concentration-dependent manner .However , IgG antibodies extracted from sera of healthy controls did not suppress lymphocyte proliferation (P>0.05).The suppression effect of β1-AA was inhibited after binding to antigenic peptides corresponding to β1-AR-ECⅡ and was completely blocked by metoprolol, a specific antagonist of β1-adrenergic receptor (β1-AR).In addition,β1-AA had no effects on the ratio of CD4+/CD8+T lymphocyte .Conclusion β1-AA isolated from DCM patients suppresses the pro-liferation of CD4+T lymphocytes through β1-AR pathway , which indicates that β1-AA can directly reduce the number of T lymphocytes and impair the function of T lymphocytes , resulting in immune system disorders and the development of DCM .

Objective To observe the Leu72Met single nucleotide polymorphism (SNP)of ghrelin gene and the relationship with essential hypertension (EH).Methods Polymerase chain reaction -restriction fragment length polymorphism (PCR -RFLP)was used to detect the Leu72Met SNP of ghrelin gene in 210 EH patients and 220 healthy controls.The plasma ghrelin was detected by radioimmunoassay method collected from all subjects. Results There were three types of polymorphism of ghrelin gene at the base site Leu72Met.There were significant differences in the genotypes (CC,CA,AA)and alleles (C,A)between the EH patients and the controls (χ2 =6.054,P =0.048;χ2 =5.866,P =0.015).In EH group,the plasma ghrelin level in subjects who were homozygous CC without mutant was not only significantly lower than those who were heterozygous CA,but also lower than those who were nucleotide homozygous mutant AA (t =-8.738,P =0.000;t =-5.103,P =0.000).The patients with CC genotype had higher SBP (t =4.298,P =0.000;t =2.236,P =0.019)and lower HDL -C (t =-11.682,P =0.000;t =-7.872,P =0.000).The patients with A allele had lower plasma ghrelin (t =-16.264,P =0.000), HDL -C (t =-15.332,P =0.000)and higher SBP(t =3.800,P =0.000),DBP(t =11.895,P =0.000),and LDL -C (t =38.401,P =0.000).Conclusion The Leu72Met SNP of ghrelin gene is significantly related to the susceptibility of EH.Base mutation C to A reduced the incidence of EH.The Leu72Met polymorphism of ghrelin gene is related to the plasma ghrelin,blood pressure and blood lipid metabolism.Base mutation C to A elevated plasma ghrelin,and lowered blood pressure and blood lipid.
