In pregnant women,positive rate of thyroid peroxidase antibody(TPOAb) is approximately 3%~10%.It is still controversial whether thyroid antibody positive rate is higher in women undergoing artificial assistant reproductive technologies.TAI might have a negative effect on pregnant outcome,which has been proved in different groups of women.Intravenous immunoglobulin,thyroxin replacement therapy and selenium therapy have been used for TAI intervention.More evidence is needed to demonstrate mechanism and evaluate effect for each therapy.

Objective To evaluate the value of the use of fibrin glue in radical mastectorny for breast cancer. Method 52 patients with breast cancer were divided randomly into two groups. In one group (27 patients) fibrin glue was used during radical mastectomy, while in the other group (25 patients), fibrin glue was not used. The volume of drainage on the first postoperative day and total volume of drainage after the operation were collected and measured. The fluid accumulation underneath the flap was also observed. Result In patients with the use of fibrin glue, the amount of drainage was much less compared with those without the use of fibrin glue. Having marked diversity ( P

OBJECTIVE: To observe the effects of Huobahuagen Tablets combined with irbesartan on the risk factors of IgA nephropathy. METHODS: Sixty-two patients diagnosed as IgA nephropathy were randomly divided into control group and treatment group. Thirty patients in the control group were treated with Huobahuagen Tablets (5 tablets po t.i.d.), and 32 patients in the treatment group were treated with irbesartan (150 to 300 mg po q.d.), besides the same treatment as the control group. After 3 months of treatment, the levels of blood pressure (BP), 24 h urine protein (Upr), urinary red blood cells (URBC), blood triglycerides (TG), total cholesterol (TC), albumin (Alb), alanine transaminase (ALT), white blood cells (WBC) and serum creatinine (Scr) were observed. RESULTS: After treatment, the levels of Upr, URBC and Scr in both groups were decreased, as compared with those before treatment (P<0.05 or P<0.01), and the levels of BP, Upr, URBC and Scr in the treatment group were lower than those in the control group (P<0.01). The levels of Alb in both groups were increased, as compared with those before treatment (P<0.05 or P<0.01), and the level of Alb in the treatment group was higher than that in the control group (P<0.05). CONCLUSION: Huobahuagen Tablets, when used together with irbesartan, may improve the renal function of the patients with IgA nephropathy and slow the deterioration of the disease by reducing BP, Upr, URBC and Scr.

Objective To investigate the effect of Fangjifulingtang on preventing proliferation of glomerular mesangial cells and the expression of PAI-1, so as to provide experimental evidence for Fangjifulingtang to cure chronic kidney disease. Method Glomerular mesangial cells were cultured and TNF-? was used as a stimulation to make the cells proliferate. Then Fangjifulingtang was incubated together at different doses. Cell vitality were evaluated and qualified by MTT. Cell period were analysed by Flow CytoMeter (FCM). Secretion of PAI-1 expression was measured by ELISA. Results The proliferation of Glomerular mesangial cells was inhibited (P

Objective To evaluate the efficacy of endoscopic injection hemostasis and sequential application of sandostatin in treatment of Dieulafoy's lesion. Methods After diagnosis of Dieulafoy's lesion confirmed, endoscopic injection hemostasis(EIH) together with mixture hypertonic saline and epinephrine(HSE) was performed, and then sandostatin was given consecutively for 7 days. The control group included the patients who were not given sandostatin or given just for 1 to 2 days. Results The rates of recurrent bleeding and transfer into surgery in sandostatin group were significantly lower than those in control group,(12.5% and 6.3% versus 53.8% and 46.2% respectively, P

10 U/ml was determined as positive value.Urinary NMP 22 protein was elevated in 22 cases.Bladder cancer was diagnosed in 11 cases.The sensitivity and specificity of the NMP 22 test were 100%(11/11) and 81%(46/57),respectively.Cystoscopy alone identified 35% of the cancers (4/11).Among 22 cases with elevated NMP 22,1 case was dignosized as bladder cancer during 1 year visit. Conclusions Urine NMP 22 is a new useful marker in early diagnosis of bladder cancer.

Objective To investigate the clinical value of multi-slice spiral CTA ( MSCTA ) and image-post processing techniques in diagnosis of acute aortic syndrome ( AAS) .Methods 71 patients with AAS were scanned by TOSHIBA Aquilion 64-slice spiral CT,the images on axial and 2D/3D were analyzed.Results 71 cases included 48 cases of aortic dissection ( AD) ,10 cases of intramural hematoma ( IMH) and 13 cases of penetrating atheroscle-rotic ulcer ( PAU) .MSCT depicted the imaging features of AAS:AD showed intimal flap and true and false lumens;IMH showed crescent or circular thickening of aortic wall .PAU showed a niche filling with contrast medium and pro-truding the aortic lumen ,where narrow neck signwas shown .The location ,radiological diagnosis and complications of AAS were observed in 71 patients.Intervention treatment or surgical treatment was conducted in 27 cases after defi-nite diagnosis .Conclusion MSCT is a fast and noninvasive examination technique , and it can provide important information for the diagnosis and treatment of AAS .

Objective To discuss and evaluate the value of multi slice spiral CT angiography in the diagno -sis of penetrating atherosclerotic ulcer materials .Methods 17 patients of PAU were collected and examined with MSCT,the location,radiological diagnosis and complications of PAU on axial ,CTA and 2D/3D images were analyzed. Results Ulcer-like aortic projections were observed of 17 patients,and connected with aortic cavity ,where narrow neck sign was showed .The indirect signs included localized or extensive IMH ,calcification of aortic wall and dilata-tion of aorta .Conclusion Multi slice spiral CT angiography is an effective method for the diagnosis of PAU by provi -ding valuable information for the diagnosis and treatment .

BACKGROUND:The biological substances fixed onto the implant surface, including specific proteins, enzymes, polypeptides, could promote the proliferation and differentiation of osteogenic cells in order to achieve a good osteogenic effect.
OBJECTIVE:To introduce the biological characteristics of the arginine-glycine-aspartic acid (RGD) peptides, cellbiological behavior and implant osseointegration in osteoporosis.
METHODS:Authors retrieved the relevant articles in PubMed database (January 1984 to January 2013), Wanfang database (January 2002 to December 2012) and CHKD database (January 2002 to December 2012) using the key words“RGD peptides, osteoporosis, bone marrow mesenchymal stem cells, osseointegration, osteoblast, induced differentiation”. Papers were included concerning the biological characteristics of RGD peptides, the biological behavior of cells and the bone-implant integration in osteoporosis.
RESULTS AND CONCLUSION:Osseointegration on the surface between implant and bone tissue can be further improved by grafting biological y active substance. Bionics modification, to simulate the extracellular matrix environment in vivo, can promote celladhesion and growth, which is an effective way to improve osseointegration and is also an important direction of research in the field of tissue engineering recently. The future research is focused on designing specific and efficient polypeptides and simple and effective fixation methods.
