The epidemic characteristics of differentiated thyroid cancer(DTC)are changing, thyrotropin(TSH)suppressive therapy is also improving in recent years. The risks of recurrence and the death of patients, as well as the adverse effects of levothyroxine sodium treatment should be fully considered during thyroid hormone administration for patients of DTC. Hence, the degree of TSH suppression should be individualized in patients with DTC.

Objective To observe the efficacy of Qingre Jiangzhuo prescription in the treatment of overweight subjects of type 2 diabetes mellitus. Methods Two hundred and four cases were divided into 2 groups in a randomized, paralleled, contrast, prospective study. The control group was treated with metformin tablet and the trial group was treated with Qingre Jiangzhuo prescription. The efficacy and safety of the two groups were compared on HbAlc, FBG, P2BG, TC, TG, BMI and AE after 12 weeks. Results After treatment, all indexes of the trial group were markedly improved compared with before treatment (P 0.05). The rate of AE in the trial group was less than that in the control group. Conclusion Qingre Jiangzhuo prescription has curative effect on type 2 diabetes mellitus patients with better safety.

OBJECTIVE To evaluate the method of prevention and treatment from the analysis of the nosocomial infection of lower respiratory tract among lung cancer patients.METHODS The information of lung cancer during 2003-2005 in our hospital was reviewed,and statistically analyzed.RESULTS Nosocomial infection rate of lower respiratory tract among lung cancer patients was 7.22%;the case-times rate of infection was 8.84%.The Gram-negative bacteria and fungi strains were major species.CONCLUSIONS Do well in preventing and controlling lower respiratory tract infection and appropriate usage of antibiotics could decrease the death of lung cancer inpatients with nosocomial infection.

T),resulting in His to Leu(CAT→CTT) substituted at codon 435(H435L).No mutation was identified in the patient's parents.HT occurred in the patient during following-up.Conclusion H435L mutation in exon 10 of TR? gene leads to resistance to thyroid hormone.Meanwhile,consistent RTH might lead to HT.

Objective To investigate the effects of Shuxuetong on hemodynamics and serum sICAM-1,IL-6,TNF-α in patients with cerebral infarction.Methods A hundred patients with cerebral infarction were randomly divided into observation group and control group from Jan 2011 to Jan 2015.Fifty patients in control group were treated with conventional therapy alone and 50 patients in observation group were treated with conventional therapy combined with intravenous injection with Shuxuetong.The changes of hemodynamics were observed before and after treatment and the levels of serum sICAM-1,IL-6,TNF-α were detected by enzyme linked immunosorbent assay (ELISA).Results No statistical significance was found in hemodynamics of control group before and after treatment (P ＞0.05).The indexes of hemodynamics in observation group were significantly improved compared with those in observation group before treatment and those in control group after treatment (P＜ 0.05).The levels of serum sICAM-1,IL-6,TNF-α were significantly reduced in two groups after treatment (P ＜0.01) and the levels of serum sICAM-1,IL-6,TNF-α after treatment were significantly lower in observation group than those in control group (P＜0.01).Conclusion Shuxuetong can effectively improve the indexes ofhemodynamics and reduce the levels of serum sICAM-1,IL-6 and TNF-α.It has a positive effect on the treatment of cerevral infarction.

Objective To assess the contractility of levator ani muscle in postpartum female using pelvic floor three-dimensional ultrasound and to provide an effective imaging basis for the change of levator ani muscle contractility in postpartum female.Methods Totally 75 postpartum women (55 underwent spontaneous vaginal delivery and 20 underwent selective cesarean delivery) and 40 nulliparas were examined by pelvic floor three-dimensional ultrasound.The images were obtained at rest and at maximal levator ani muscle contraction.The sagittal hiatal length (L) on the two-dimensional sagittal images,the area of levator hiatus (A) and the circumference of levator hiatus (C) were measured on the three-dimensional images,and the difference value between rest and contraction were calculated to get the △L,△A,△C.Then the △L,△A,△C between different groups were compared.Results The △L,△A,△C in spontaneous vaginal delivery group and selective cesarean delivery group were smaller than those in nulliparas group (P ＜0.05),and there was no statistical difference between spontaneous vaginal delivery and selective cesarean delivery group (P ＞ 0.05).Conclusions Three-dimensional ultrasound can effectively assess the the contractility of levator ani muscle,the levator ani muscle contractility of postpartum female was poorer than nulliparas,and between spontaneous vaginal delivery and selective cesarean delivery women there is no obvious difference.

Objective The aim of this study is to establish a practical VX2 tumour model less than or equal to 10 mm from large blood vessel(as standard) for HIFU ablation .Methods 15 New Zealand rabbits were involved ,VX2 tumour blocks were inoculated near postcava through spine path ,and tumour rate was observed two weeks later by anatomy and MRI .Results Three experimental rabbits did not survive ,all the rest of the 12 into the tumour ,assembly tumour rate was 100% (12/12);The tumour rate reaching the standard accounted for 75% (9/12) ,the average distance between the tumour and the inferior vena cava was (5 .6 ± 3 .4)mm . Conclusion It is feasible to establish the VX2 tumor model less than or equal to 10 mm from large blood vessel through spine path .

Objective To investigate the stress distribution in various tooth heights of ferrule effect in post crown,and to evaluate the biomechanical mechanism in post crown.Methods The three-dimensional finite element entity grid model was constructed,which was a maxillary central incisor restored with post and porcelain fused to metal crown (PFM crown).By imitating the various tooth heights under static loading,the dentin stress was analyzed.Results The stress distribution had an increasing tendency from tooth cervix to root,but it could be decreased by ferrule structures and the decrease degree accorded with the region and height of ferrule.The ferrule effect of the wrapping 1 cm coronal tooth could decrease the stress of the tooth cervix obviously but 2 cm decreased a little.Conclusion The crown wrapping 1 cm coronal can produce ferrule effect obviously and protect the tooth.We can choose to use crown wrapping 2 cm coronal to care the tooth condition.

Objective To detect circulating CD4 + CD25 + regulatory T cells (Treg) and Toll-like receptor(TLR)2 and TLR4 expression on the peripheral blood mononuclear cells (PBMCs) of patients with HBV-related liver cirrhosis (LC), and to explore the correlation between them. Methods PBMCs isolated from 30 LC patients, 21 chronic hepatitis B (CHB) patients and 16 normal controls(NC) were stained with fluorescent labeling anti-TLR2-PE, anti-TLR4-APC, anti-CD14-FITC monoclonal antibodies and anti-CD4-PerCP, anti-CD25-FITC, anti-CD127-PE. Samples were detected by flow cytometry. Statistic analysis be-tween groups was performed by Kruskal-Wallis H test. Spearman rank correlation was used to analyze the correlation of Treg and TLR2, TLR4. Results The expression of TLR2 and TLR4 were significantly up-reg-ulated in patients with LC than those in the controls (TLR2 : 200.3 ± 96.8 vs 94.1 ± 17.6, P < 0.05 ; TLR4:32.1 ±7.2 vs 17.8 ±3.9, P<0.05). The expression of TLR4 was significantly increased in pa-tients with LC than those in patients with CHB (TLR4 : 32. 1 ± 7.2 vs 25.2 ± 8.3, P < 0.05), but there were no differences of TLR2 expression between LC and CHB(200.3 ± 96.8 vs 214.0 ± 72.6, P > 0.05). Treg/CD4+ T cells were 5.07% ±1.43%, 5.88% ±1.66%, 4.21% ±1.24% in patients with LC, CHB and NC, respectively. Treg/CD4+ T cells were significantly increased in patients with CHB than those in pa-tients with NC(P<0. 05) and LC(P <0.05), but there were no differences between LC and NC(P > 0.05). TLR4 expression and Treg were positive correlation (r = 0. 469, P = 0. 032) and TLB2 expression were negative correlation in patients with LC (r = -0.428, P = 0.021). Conclusion The expression of TLR2 and TLR4 were up-regulated on PBMCs in patients with LC. It seems to be expression of TLR2 and TLR4 in-volved in the pathogenesis of LC.
