PurposeThe restriction of strain ratio (SR) in the diagnosis of thyroid malignant tumor are caused mainly because of disadvantages including low sensitivity, in this research the authors used different calculation methods of strain ratio based on the size of tumors, to explore the clinical application value of them on the differentiation of benign and malignant thyroid nodules.Materials and Methods Data of 336 patients with thyroid nodule (340 nodules) who underwent elasticity imaging and ultrasound-guided fine-needle aspiration were retrospective analyzed, with the pathology combined follow up acted as golden standards, fixed surface area assay and true surface area assay of strain ratio were compared on the differential diagnosis of benign and malignant thyroid nodules with various size.Results Among 340 thyroid nodules, there were 91 small nodules and 249 big nodules. Pathological results showed that 36 of 91 small nodules and 104 of 249 big nodules were malignant, while the others were benign. The true surface area assay was significantly better for the diagnosis of smaller thyroid nodules with longitudinal diameter and transverse diameter<8 mm with higher consistency with pathology (χ2=20.89,P<0.01), and fixed surface area assay is more suitable of thyroid nodules with longitudinal diameter and transverse diameter>8mm (χ2=57.08,P<0.01). The sensitivity, specificity and consistency for the diagnosis of malignant nodules of true surface area assay were 57.10%, 83.00% and 72.30% (Kappa=0.413), which were 73.60%, 85.00% and 72.30% (Kappa=0.590) in the fixed surface area assay, and 85.00%, 85.50% and 85.30% (Kappa=0.699) in the selective usage of two methods according to the tumor size, respectively.Conclusion The sensitivity is highest when using the two methods selectively according to the nodule size, with a better consistence rate with pathological results as well.

Objective: To establish a method for simultaneously determination of five isoflavones (daidzein, daidzin, puerarin, mirificin, and 6″-O-xylosidepuerarin) in Pueraria Radix by single marker (QAMS), which is feasible and accurate. Methods: Puerarin was taken as internal standard substance to establish the relative correction factor (RCF) for quantitative analysis of multi-components with QAMS. Thus, the contents of mirificin, 6″-O-xylosidepuerarin, daidzin, and daidzein were calculated. The contents in 10 batches of samples were determined by external standard method and QAMS. The scientificalness and feasibility of the methods were evaluated by comparison of the quantitative results between external standard method and QAMS. Results: The reproducibility of RCF was perfect. The results calculated with QAMS were consistent with the results by the external standard method. Conclusion: QAMS is accurate and feasible to evaluate the quality of Pueraria Radix.

Background Human leucocyte antigen (HLA)-B27-associated uveitis is one of the most common causes of non-infectious uveitis.T helper 17 (Th17) cells play an important role in human autoimmune diseases,but the pathology research on the production of Th17 cells in acute anterior uveitis patients positive for HLA-B27 was rarely reported.Objective The aim of this study was to investigate the expression and significance of the peripheral blood T helper cell subsets (Th1,Th2,Th17) in acute anterior uveitis patients positive for HLA-B27.Methods This study meets the criteria of the Helsinki Declaration.Informed consent was obtained from all the participants.A prospective cohort design was used in this study.Twenty-two patients with acute anterior uveitis positive for HLA-B27 were enrolled from Affiliated Second Hospital of Nanjing Medical University,and 16 normal healthy subjects with matched gender and age were enrolled as controls.The expression of interferon-γ (IFN-γ),interleukin-4 (IL-4) and IL-17 on lymphocytes (CD4+) in blood were assessed by flow cytometry,and immunoturbidimetry was used to detect the C reactive protein (CRP) level in blood.The degree of the severity of disease was evaluated by clinical scoring.The correlations between the percentage of IFN-γ+Th1,IL-4+Th2,or IL-17+Th17 with clinical factors and CRP were analyzed.Results The percentages of IFN-γ+Th1 and IL-17+Th17 in the peripheral blood were (23.11 ±9.69) ％ and (3.96±2.92) ％ in the patient group,showing a significant increase in comparison with (16.00±4.26)％ and (1.68±0.60) ％ in the control group (P=0.041,P=0.002).However,the IL-4+Th2 level was not significantly different between the patient group (0.33％ ±0.36％) and the control group (0.56％ ±0.34％) (P=0.122).No significant correlations were found between the percentage of IFN-γ+ Th1 with disease severity and CRP (r =0.197,P =0.500 ; r =0.253,P =0.383),between the percentage of IL-4+ Th2 with disease severity and CRP (r =0.068,P =0.817 ; r =0.439,P =0.116) as well as between the percentage of IL-17 + Th17 with CRP (r =0.226,P =0.436).However,a positive correlation was seen between the percentage of IL-17+ Th17 with disease severity (r =0.805,P =0.001).Conclusions IFN-γ and IL-17 in human CD4+T cells are significantly elevated in the blood of HLA-B27-related acute anterior uveitis patients.Disease severity is associated with the percentage of IL-17 +Th17,suggesting that Th1 cells together with Th17 cells participate in the pathogenesis of the disease and Th17 cells might play a dominant role in the disease.

Objective To summarize the common types and clinical characteristics of ureter disease;which can increase manipulation difficulties and adverse events during rigid ureteroscopic procedures. Methods From Jan 2001 to Dec 2010,our team performed 317 rigid ureteroscopic Drocedures for ureteroscopic examination or treatment;including 60 difficult procedures(34 male and 26 female).The mean age of the patients was 37 years (range,18 to 71).The ureteral diseases were classifted into five types according to the pathological characteristics:Type Ⅰ calculous stenosis,Type Ⅱ neoplastic stenosis;Type Ⅲ non-congenital stenosis,Type Ⅳ congenital stenosis,Type Ⅴ expansion of tortuous ureters.The operative time,complications,and conversion to open surgery were evaluated,and the therapeutic methods were analyzed. Results Of the 60 difficuhly-manipulated procedures,the mean manipulated time was 75 min (range,31 to 200).Intra-operative complications occurred in 9 procedures,including 4 cases of mucosal bleeding,2 cases of submucosaI false passage and 3 cases of ureteral perforation.Eleven procedures were converted to open surgery. In five procedures only a double J tube was inserted for drainage due to the difficulty of entering the ureter.Fiftyfive patients were followed up for 17 months (range,3 to 110);48 patients were cured,5 patients improved and 2 patients were unchanged. Conclusions The five types of ureteral disease can increase operative difficulties and risks of rigid ureteroscopic procedures.We should be cautious during surgery and should stop manipulation or convert to other surgeries if necessary.

Objective To evaluate the expression of macrophage migration inhibitor factor (MiF) and cyclinD1 in pancreatic carcinoma and their relationships with clinical pathology characteristics. Methods The expression of MIF and eyclinD1 in 89 carcinoma and 5 normal pancreatic tissues was detected with immunohis-tochemistry methods, and the relationships among MIF and cyclinD1 expression and clinicopathological factors were studied. Results The overexpression of MIF and cyclinD1 was found in 88.8%, and 50. 6% of pancre-atic carcinoma tissues respectively. The overexpression of MIF had a significant correlation with Ⅰ,Ⅱ,Ⅲ,Ⅳ tumor stage (69. 2%, 94. 7%, 96. 4%, 100%, P <0.05), while the positive expression rate of cyclinD1 only had a significant correlation with tumor stages Ⅲ,Ⅳ (33. 3%, 68. 8%, P <0. 05). Both of the two proteins had a correlative tendency with pathological grade and lymph node metastasis. The different expression of MIF between pancreatic carcinoma with and without liver metastasis had no statistical significance, (100% ,85.9%, P >0. 05)while there was a statistically significant difference about cyclinD1 (66. 7% ,46. 5% ,P <0. 05). A significant positive correlation was also found between MIF and cyclinD1 (P < 0. 05). Conclusion The ex-pression of MIF and CyclinD1 was higher in pancreatic cancer tissues than in normal tissue, and they may be associated with the malignant stage, tumor differentiation, local lymph node and liver metastasis of this tumor.

OBJECTIVETo explore the correlation between hand and face-mouth, so as to provide nerve reflex basis for the theory "Hegu (LI 4) regulates face and mouth".

METHODSSeven hundred and sixty-three participants who met the inclusive criteria were divided into different age groups. The skin around participants' thenar eminence was gently scraped to be observed whether there was an involuntary movement around the face or mouth, which was palmomental reflex. The results of palmomental reflex were recorded.

RESULTSThe total occurrence rate of palmomental reflex was 46.26%. For those who were 0 to 1 years old, the palmomental reflex was all positive; for those who were 21 to 36 years old, the positive rate was 20.45%, which was the lowest; for those who were 65 to 85 years old, more than half of them were positive. The majority of those who were 0 to 2 years old were bilateral positive palmomental reflex, while the majority of those who were 65 to 85 years old were unilateral positive palmomental reflex.

CONCLUSIONThere is a certain connection between hand and face-mouth. The occurrence rate of palmomental reflex changes from high to low over age increasing, and then changes from low to high with the aging, presenting a "high-low-high" U-shaped curve, which is possible related to the growth and recession of nervous system.
