Thyroid cancer is the most common malignant tumor of the human endocrine system. A papillary thyroid microcarci-noma (PTMC) is usually defined as a papillary thyroid tumor that is less than 10 mm in diameter. The incidence of thyroid cancers has obviously increased in recent years. The surgical treatment of PTMC differs in China and overseas. Aside from conventional surgery, novel surgical methods, such as ultrasound-guided percutaneous ablation, have been used for the surgical treatment of PTMC. This arti-cle mainly discusses the research progress in the surgical treatment of PTMC.

The effect of tranilast on the down- regulation of beta- adrenoceptor agonist was investigated. Male guinea pigs were divided into 3 groups, one group is control. Others were received injection of terbutaline or terbutaline plus tranilast for successive 5 days. The radioli-gand binding assays for beta-adrenoceptors in the lung membranes of the guinea pigs were per-formed. The results showed the numbers of maximal binding sites (Bmax) of beta-adrenoceptors in terbutaline group was significantly less than that in control group ( P 0. 05).The affinity ( Kd) of beta-adrenoceptors both in terbutaline group and in terbutaline plus tranilast group was higher than that in control (P

Objective:To study the therapeutic effect of Liyanling granules on chronic pharyngitis. Methods:The chronic pharyn-gitis rat models were established, and administered orally for 7 days. The influence of Liyanling granules on the pathology of pharyngeal tissue and the contents of PGE2 , IL-1β and TNF-α were observed. The blood was withdrawn to detect the whole blood viscosity and plasma viscosity, and the anti-inflammatory effects were observed in two kinds of rat models:foot pad swelling induced by carrageenin and agar-induced chronic granuloma. Results:Liyanling granule could significantly decrease the levels of PGE2 , IL-1βand TNF-α( P<0. 05 or P<0. 01) and the viscosity of blood and plasma(P<0. 05 or P<0. 01), improve the pathological morphology of rat pharynge-al tissues(P<0. 05 or P<0. 01), inhibit the swelling of foot pad induced by carrageenin and the granuloma induced by agar in rats(P<0. 05 or P<0. 01). Conclusion:Liyanling granules has a certain therapeutic effect on chronic pharyngitis in rats, and the mecha-nism may be related with the inhibition of inflammatory cytokines PGE2 ,IL-1β and TNF-α and the improvement of blood rheology.

Objective:To explore the effect and mechanism of SanQi HuoXue pills in the treatment of acute soft tissue injury. Methods:Totally 140 wistar rats were randomly divided into the control group, model group, posistive drug group, and Sanqi Huoxue pills group respectively at the dose of 0. 5,1. 0,2. 0 g·kg-1 . The rat model of acute soft tissue injury was used to observe the influence of Sanqi Huoxue pills on the content of PGE2 , IL-6, NO and SOD on the 3rd and 5th day after the administration, and the effects of the pills on the whole blood viscosity and plasma viscosity were studied as well on the 5th day. Results: After the administration of the pills, the levels of PGE2 , IL-6 and NO, the blood viscosity and plasma viscosity were decreased significantly, and the level of SOD was increased significantly(P<0. 01 or P<0. 05) when compared to model group. Conclusion:Sanqi Huoxue pills have therapeutic effect on acute soft tissue injury in rats. Free radical, PGE2 , IL-6 and blood hemorheology play important roles in the formation of acute soft tissue injury.

Objective Investigation and analysis of intelligence and psychomotor function in children born after implementingt universal salt iodization(USI). Methods Historical serious illness areas of water iodine below 10μg/L were selected as study sites, water iodine in 50 - 100 μg/L in the historical non-endemic areas were as control points in Henan, 2008. Cluster sampling was used to select children aged 6 - 15 years as observing subjects,IQ were measured with CRT- Man Test(CRT-C2). A "Tianjin Medical psychomotor test battery" (JPB) was carry out to test psychomotor function. Results In IDD regions 230 children were surveyed post-USI and 1284 children preUSI. The IQs post and pre USI were 99.3 and 99.9, respectively, and the proportion of IQ ≤69 were 2.17%(6/230) and 2.80%(36/1284), respectively. In non-IDD regions 650 children were surveyed post-USI and 2079children pre-USI. The IQs post and pre USI were 95.3 and 93.8, respectively, and the proportion of IQ ≤ 69 were 2.31%(15/650) and 3.37%(70/2079), respectively. In IDD regions, the abnormal rate of T scores and damage index post USI were 3.6%(2/56), 5.3%(3/56), respectively, significantly lower than pre USI [18.1%(29/160),18.1%(29/160), x2 = 7.54, 6.86, all P ＜ 0.01]. Conclusions USI could increase the IQs of children and decrease the positive rate of JPB, and significantly improve the quality of whole nation and persistently eliminating IDD.

Familial non-medullary thyroid carcinoma (FNMTC) is de fi ned as the presence of two or more affected fi rst-degree relatives with non-medullary thyroid cancers without other known familial syndromes. FNMTC is one of the most inheritable forms of all cancers, with a high risk of a first-degree relative developing the disease. Compared with sporadic non-medullary thyroid carcinoma (NMTC), FNMTC presents at a younger age and is associated with a higher incidence of multifocal disease and metastasis. This in-creased aggressiveness has been hypothesized to translate into higher recurrence rates and decreased survival of patients with FNMTC. The genes involved in the pathogenesis of FNMTC are yet to be elucidated, although some recent studies identified several predisposi-tion loci with a high degree of genetic heterogeneity. Since 2005, next-generation sequencing (NGS) technologies have been developing as rapid, high-throughput, and cost-effective approaches to fulfill medical sciences and research demands. With the use of NGS, the un-derlying causative genes can be directly distinguished via systematic filtering, through which the identified gene variants are verified for novelty and functionality.

Objective To evaluate the clinical application of digital radiography(DR)tissue equalization(TE)technique in the femoral neck injury.Methods TE technique and conventional photography were used to examine 50 patients suffering from injury of the femoral neck.The image quality was evaluated by three radiological experts who were blinded to the results.The image quality was divided into five levels.Results When the TE technique was used,38 perfect images were obtained and there was no unacceptable image,while the traditional methods resulted in 12 unacceptable images and no perfect image.The TE technique is superior to the conventional radiography significantly in the lateral photography of the femoral neck(P
