Objective To investigate the clinical value of galectin-3 expression on fine needle aspiration (FNA) smearsandtissueslicesof thyroid tumors in distinguishing benign from malignant tumors. Methods Galectin-3 expression on FNA smears and tissue slices of thyroid tumors from 72 thyroidectomy specimens was detected by immunochemical method (SP method). Results Galectin-3 expression was high on FNA smears and tissue slices of malignant thyroid tumors, whereas there was no or low expression of galectin-3 on FNA smears and tissue slices of benign thyroid tumors. The difference of positive rates of galectin-3 expression between malignant and benign thyroid tumors was significant on both FNA smears and tissue slices (? 2=43.73 and ? 2=48.16, respectively, both P0.05). Conclusion Galectin-3 expression is different between benign and malignant tumors. Galectin-3 expression level is higher in FNA smears and tissue slices of malignant thyroid neoplasms than that of benign ones, suggesting that galectin-3 is a reliable molecular marker in distinguishing benign from malignant thyroid tumors. Galectin-3 expression with immunochemical method may be used in diagnosing benign or malignant thyroid tumors.

BACKGROUND:Bone marrow mesenchyme stem cells are important non-hematopoietic stem cells in the bone marrow, which can stimulate angiogenesis. While, Slit can also stimulate angiogenesis, as many studies have proved. OBJECTIVE:To review the biological functions, clinical application and effects of bone marrow mesenchymal stem cells and Slit2 on promoting angiogenesis. METHODS:A computer-based online research of CNKI and PubMed databases was performed to col ect articles published between 1980 and 2014 with the keywords“MSCs”and“Slit2”in Chinese and English. There were 436 articles after the initial survey. Final y, 65 articles were included according inclusion and exclusion criteria. RESULTS AND CONCLUSION:Both bone marrow mesenchymal stem cells and Slit2 play an important role in promoting angiogenesis, but the relevance of bone marrow mesenchymal stem cells and Slit2 is stil controversial. If assuming that bone marrow mesenchymal stem cells secrete Slit2, more researches should be done to reveal whether bone marrow mesenchymal stem cells promoting angiogenesis is relevant to Slit2 and through which signaling pathway Slit2/Robo functions to adjust bone marrow mesenchymal stem cells thus to promote angiogenesis. If relevant, the transplantation of the Slit2 and bone marrow mesenchymal stem cells wil be a promising treatment of cerebral infarction and other central nervous injuries.

Background and purpose:T-cell non-Hodgkin’s lymphoma(T-NHL) has relatively high incidence in Asian countries, and the incidence rate showed an upward tendency. It has a dual characteristic of both ethnic and regional. We conducted this study in order to analyze the clinical characteristics, pathological type and survival of T-NHL in our hospital. Methods:Records of 50 cases with T-NHL treated from Jan. 2002 to Dec. 2012, were analyzed in terms of clinical characteristics, distribution of pathological type and survival. Results:Patients with T-NHL account for 24%of NHL cases in our study. Of the 50 cases, 37 were Han, 13 were Uygur;The most frequent type was NK/T cell lymphoma(NK/TCL)(16/50, 32%). We performed pathological type for each age group:4 cases with children’s group were all T-lymphoblastic leukemia/lymphoma(T-LBL)(4/4,100%), the most frequent type of youth and middle age group was NK/TCL(8/20, 40%;7/13, 53.8%), as the senile group was angioimmunoblastic T-cell lymphoma(AITL)(6/13, 46.2%). There was also a signiifcant difference in pathological type between the stage, with stageⅠ-Ⅱwere all NK/TCL(12/12, 100%), stageⅢ-Ⅳwere observed with peripheral T-cell lymphomas-unspeciifed(PTCL-U)(9/38, 23.7%) and AITL(9/38, 23.7%). The frequent type of Han was NK/TCL(14/37, 37.8%), as the Uygur was T-LBL(5/13, 38.5%). The median overall survival(OS) time was 12 (ranged 0-112) months. The 5 year OS rate was 39%. Both pathological type and age group were important factors influencing survival. The difference in outcome for the pathological type(P<0.05): NK/TCL and anaplastic large cell lymphoma(ALCL) had the better 3 year OS rates(71%, 61%), but PTCL-U and T-LBL had poor prognosis(19%, 7%). Age did a signiifcant effect on OS(P<0.05):children’s group had the worse 5-year OS rate (0%), middle age group had a better prognosis (67%), the OS of the youth group was 35%, for the senile group was 21%. Conclusion:T-NHL in Xinjiang region have their unique clinical characteristics:The overall incidence rate was similar with the domestic report, however, higher than the reports abroad. The incidence of Han was higher than Uygur. Pathological type showed in this study was different from that in European and American countries. There was a significant difference in distribution of pathological type in different age group, stage and nation. The long-term survival and prognosis of patients in Xinjiang region was poor. Both pathological type and age group were important factors inlfuencing survival.

Soxhlet extraction is a common method of sample preparation. However, there has been no discussion about the efficiency of Soxhlet extraction from different batches and the factors that cause content fluctuation. In this study, Panax ginseng was selected as a model sample. Soxhlet extraction by means of a water bath, which has always been neglected, was identified as a novel key factor in the poor repeat-ability in different batches of Soxhlet extraction, as it can affect the siphon times and reflux time, which have been positively correlated with the ginsenoside contents. By substituting round bottom flasks in the same column, the relative standard deviation of the most fluctuated compound, ginsenoside Rb1, was decreased from 24.6% to 5.02%. Scanning electron microscopy analysis confirmed that the breakdown of the surface of the ginseng powder in the Soxhlet extraction led to a better dissolution of ginsenosides, indicating that chloroform may promote the extraction of ginsenosides by disrupting the cell structure. Moreover, 70% methanol was regarded as the better solvent for extracting the ginsenosides. Overall, this work offers a practical and effective protocol for improving the accuracy and repeatability of Soxhlet extraction methodology for ginsenosides and other analytes.

BACKGROUND:It is important to maintain the height of joint line in total knee arthroplasty or renovation. Foreign scholars have reported the parameters of the distance from different landmarks to knee joint line, but there is stil a lack of relevant data for Chinese people. OBJECTIVE:To explore the relationships of the knee anatomic landmarks and joint line in normal Chinese, thereby providing clinical evidence for primary total knee replacement and knee renovation. METHODS:Totaly 746 normal knee joints of 409 healthy volunteers from North China and Southwest China were randomly enroled, including 214 males and 195 females, with a mean age of 37.7 years. CT scan was used to reconstruct the three-dimensional knee joint, and the distance between the anatomic landmarks and the joint line was measured using Mimics software. RESULTS AND CONCLUSION:The distance from the center of femoral medial sulcus to the joint line was (25.72±2.52) mm. The distance from the center of lateral femoral condyle prominence to the joint line was (26.30±2.65) mm. The distance from the adduction muscle tubercle to the joint line was (44.60±4.32) mm. The distance from the peak of the tibial tubercle to the joint line was (21.50±3.57) mm. These parameters in male group were significantly higher than those in female group (P < 0.05). In conclusion, these findings provide anatomic evidence for the recovery of joint line in knee replacement or renovation; the variability of the distance from the center of femoral medial sulcus, lateral femoral condyle prominence and adductor tubercle to the joint line is smaler, and therefore, these landmarks have more reference values in total knee arthroplasty.
