OBJECTIVETo observe the clinical efficacy of Jiakangling Capsule (JC) combined with reduction of 1311 in treatment of Graves hyperthyroidism.

METHODSTotally 387 Graves hyperthyroidism patients were randomly assigned to the treatment group (200 cases) and the control group (187 cases). Patients in the treatment group took JC combined with reduction of 131I. The 131I dosage per gram of thyroid tissue was 50-80 microCi. They additionally took JC one week after taking 1311 for one consecutive month. Patients in the control group took 131 routinely as one disposable treatment. The 131I dosage per gram of thyroid tissue was 70-120 microCi, without using JC or other anti-thyroid drugs. All patients were reexamined after 24-month treatment. Whether hyperthyroidism was cured, incurred, or permanent was observed. Efficacies of thyroglobulin antibody (TGAb) and thyroid microsome antibody (TMAb) were compared between the two groups.

RESULTSCompared with the control group, the incurred ratio increased in the treatment group [3.2% (6/187) vs. 16.0% (32/200), P < 0.01], the incurred ratio of strong positive TGAb and TMAb patients increased [3.5% (2/57) vs. 27.1% (16/59), P < 0.01], the permanent hypothyroidism ratio decreased [21.1% (12/57) vs. 3.4% (2/59), P < 0.05 ].

CONCLUSIONJC combined with reduction of 1311 was superior in treating Graves hyperthyroidism induced permanent hypothyroidism than routine 1311 treatment, especially for strong positive TGAb and TMAb patients.

Objective To explore the relationship of psychological flexibility and the anxiety ,depression in ischemic cerebrovas‐cular disease (ICVD) patients .Methods Two hundred cases of ischemic cerebrovascular disease were collected ,and their anxiety and depression level and psychological flexibility were measured by self‐evaluation of anxiety scale (SAS) ,self‐evaluation of depres‐sion scale (SDS) ,acceptance and action questionnaire‐Ⅱ (AAQ‐Ⅱ ) and cognitive fusion questionnaire (CFQ ) .According to the test results ,the patients with anxiety and depression were divided into different degree :degrees :normal ,mild ,moderate or severe . Results The AAQ‐Ⅱ and CFQ of the patients with anxiety depression were significantly higher than normal emotional ICVD pa‐tients (P<0 .01);there were statistical significance in the difference of the level of AAQ‐Ⅱ and CFQ and the degree of anxiety and depression in these patients (P<0 .01);the level of AAQ‐Ⅱ and the degree of anxiety depression was positively correlated (r=0 .778 ,P<0 .01 ;r=0 .759 ,P<0 .01);the level of CFQ and the degree of anxiety depression was positively correlated (r=0 .785 , P<0 .01 ;r=0 .774 ,P<0 .01);with SAS ,SDS ,as dependent variable ,the AAQ‐Ⅱ ,CFQ as independent variables ,through multiple linear regression analysis ,suggested that psychological flexibility was the impact factor of anxiety depression .Conclusion For pa‐tients with ICVD ,psychological flexibility is closely related to the degree of anxiety depression .Psychological flexibility is one of the predictor of anxiety depression .

Objective To construct miR-223 knockdown lentivirus vector and provide a tool for further study of the function of miR-223. Methods According to the Invitrogen miR-RNAi online design tool, a pair of complementary oligo?nucleotides encoding miR-223 mature sequence was designed, annealed and ligated with pcDNA6.2-GW/EmGFP-miR vec?tor. Then miR-RNAi expression cassette was cut and subcloned into lentiviral pCDH-CMV-MCS-EF1-copGFP vector. The lentiviruses were packaged and titered, and then ST2 cells were infected with viruses. The efficiency of infection was calcu?lated, and the knockdown of endogenous miR-223 was detected by using real-time RT-PCR. Results Restriction enzyme digestion and sequencing results showed that miR-223 lentivirus construct was successfully made. Lentivirus that knock?down miR-223 expression packaged and infected of target cells. The expression of GFP green fluorescent protein accounted for 80%-90%and the virus titer was 1×109 PFU/mL. The infection efficiency reached 90%. Compared with negative control virus, miR-223 knockdown lentivirus significantly down-regulated the expression of miR-223 in ST2, and was 31%(n=3, t=15.091, P<0.05). Conclusion miR-223 knockdown lentivirus is successfully made. It provides a tool for further studying the function of miR-223.

Objective: To analyze the diagnostic methods and risk factors of female lung cancer, and to investigate the role of flberoptic bronchoscopy in the early diagnosis of lung cancer. Methods: The bronchoscopy data of 238 female lung cancer patients seen in our hospital between January 2005 and December 2008 were enrolled. The fiberoptic bronchoscop-ic features with clinical imaging, main risk factors of lung cancer and the pathological types were analyzed. χ~2 test was used for statistical analysis. Results: The major pathological type of lung cancer was adenocarcinoma in females younger than 40 years and squamous cell carcinoma in patients older than 60 years. The proliferative type was correlated with squa-mous cell carcinoma. Its imaging manifestion was a mass and the main risk factor was smoking. The infiltrating type was correlated with adenocarcinoma. Its imaging manifestation was mainly pleural effusion and the main risk factor was indoor soot inhalation. Conclusion: Females exposed to indoor soot inhalation for a long time especially those with a number of risk factors should be offered a screening with low dose CT (LDCT) regularly. Fiberoptic bronchoscopy and cytohistology are of great value for early diagnosis of lung cancer in those with abnormal findings in CT.

Objective To assess the efficacy of cardiac resynchronization therapy (CRT) using real-time three-dimen?sional echocardiography (RT-3DE) and speckle tracking imaging (STI) in patients with heart failure. Methods Thirty-one patients with chronic heart failure were examined by RT-3DE and STI before CRT and 3, 6 months after CRT. The values of left ventricular end-diastolic volume (LVEDV), end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF) were measured. RT-3DE was used to evaluate the minimum regional volume for 16 segments (Tmsv-16SD) and the ratio of Tmsv16SD to R-R interval, and the maximum time difference (Tmsv-16Dif). STl was used to evaluate the ratios of standard deviation of the time to peak longitudinal radial and circumferential strain to R-R interval (Tls-16SD%, Trs-16SD%,Tcs-16SD%) from the beginning of Q wave of electrocardiography to the point minimal systolic volume of all 16 segments and the maximum time difference. Results The values of LVEDV and LVESV were smaller 3 and 6 months after CRT than those before CRT. The value of LVEF was significantly improved after CRT (P < 0.05). The values of Tmsv-16SD%, Tmsv-16Dif%, Tls-16SD%, Trs-16SD%, Tcs-16SD%and T-Dif%were gradually decreased after CRT (P<0.05). The values of Tmsv-16SD%, Tmsv-16Dif%,Trs-16SD%and Tcs-16SD%were negatively related with LVEF (r=-0.79,-0.82,-0.69 and-0.74(P<0.05). The better consistency was found between RT-3DE and STI methods(Kappa=0.77). Conclusion Re?al-time three-dimensional echocardiography and speckle tracking imaging can provide more accurate quantitative informa?tion of cardiac resynchronization therapy for assessment of treatment and prognosis in patients with heart failure.

Tumor cell metastasis is a process of extracellular matrix hydrolyzed by protease, where tumor cells traverse the defect in the extracellular matrix into the lymphatic system and the capillaries to form new metastasis hematogenously.Matrix metalloproteinases (MMPs) are a kind of enzymes closely related to the metastasis.MMP, especially the relationship between MMP-9 and endometrial cancer metastasis in this paper will be summarized to get a better understanding about it.
