Thyroid carcinoma (TC) is one of the most prevalent endocrine malignancies worldwide. Patients with TC have high overall survival, but TC experienced the largest increase in incidence. Therefore, it is necessary to get further understanding of the mechanism involved in the development and progression of TC. The concept of the competing endogenous RNA (ceRNA) further illuminates the mechanism of tumorigenesis. Current studies indicate that psedugenic RNA, lncRNA, circRNA and mRNA, all of which may take part in the construction of ceRNETs as ceRNAs. These ceRNAs harbour the same miRNA response element (MRE) as mRNAs. Thus, ceRNAs can also competitively inhibit mRNA binding to the miRNAs, which results in affecting mRNA expression to exerts a pro-oncogenic or tumor-suppressive influence in tumor. Recently, a large number of studies have shown that ceRNA molecules play an important role in the malignant behavior of thyroid cancer. Therefore, it is necessary to summarize these studies. The purpose of this paper is to classify these ceRNA molecules in thyroid cancer and to elaborate the functions of these molecules in thyroid cancer.

This study was aimed to establish a fast determination method of main components in honey. Honey samples from difference production bases were used as study objects. Transmission and reflection spectra of different honey samples were collected with the Fourier transform near infrared spectrometer. The main components in honey (moisture content, fructose content, glucose content and reducing sugar content) were detected by the near infrared quantitative analysis technique. The near infrared quantitative analysis models of moisture content, fructose content, glucose content and reducing sugar content in honey were established by the partial least squares (PLS). The results showed that the correlation coefficient (r) of the moisture content, fructose content, glucose content and reducing sugar content in honey were 0.997 25, 0.973 90, 0.927 94 and 0.952 68, respectively. The root mean square error of prediction (RMSEP) were 0.165 (%), 0.564 (%), 1.300 (%) and 1.270 (%), respectively. It was concluded that determination of main components in honey by the near-infrared spectroscopy technology was a fast and nondestructive determination method with high accuracy, which can be used in the quantitative detection of main components in honey.

This study was aimed to revise and improve the quality standard of Ping-An (PA) Pill. Fructus CaryophylliandFructus Aurantii ImmaturuswereidentifiedbyTLC.Thecontentofcostunolideand dehydrocostunolide were determined by HPLC. The results showed that there were clear spots, good degree of separation, and no negative interference in the TLC identification. The calibration curve of costunolide and dehydrocostunolide were linear at the range of 0.103 4-1.033 5μg (r=0.999 9) and 0.110 1-1.100 5μg (r=0.999 7). The average recoveries were 95.1% (RSD = 2.62%, n = 6) and 98.6% (RSD = 2.84%, n = 6), respectively. It was concluded that the method was convenient and accurate with strong specificity in the quality and quantity control of PA pill, which can be used in the quality control of PA pill.

Results:The optimal extraction conditions were as follows:water was 8 times of the medicinal materials, the decoction duration was 1. 5h with 3 extraction times. Conclusion:The optimized process of Xiaoyan granules is feasible and convenient,and the granules are qualified and stable.

Objective To investigate the effects of CBL in teaching human embryology for medical students.Methods After having seminar with clinical case, scoring rate of questions discussed and not discussed in final exam were compared in recent 3 years.Embryological knowledge were evaluated in 1, 2, 3 years after embryology class by online test.Results There is no difference of total scoring rate among 3 grades in final exam, while the score of questions discussion was significantly higher than that of non-dissaution course(P<0.01).Scoring rate of objective questions discussed was significantly higher.Scoring rate of online test decreased with years after embryology class, while questions discussed were better than not discussed.Conclusions Seminar with clinical case as CBL could improve the learning outcomes of embryology in short and long term memory.

Now human parasites are still important pathogens to harm human health.Researches on parasites have ranged from the simple aetiology to the field of studying vital phenomena by modern science.However some domestic medical colleges cut out the course of human parasitology without enough consideration.Aiming directly at this phenomenon the author has discussed the scientific orientation of human parasitology in preclinical medicine education and expounded the point of view.

About 50% malignant tumors may develop bone metastasis in advanced stage. Pain, pathological fractures and dysmotility are the main symptoms of patients with bone metastasis. Image-guided physical ablation can obviously relieve pain caused by bone metastasis, whereas imaging-guided bone cementoplasty can enhance bone stability, and has good effect on preventing and treating osteoporosis and pathological fractures. The progress of imaging-guided physical ablation, bone cementoplasty and the combination of two techniques in treatment of bone metastasis were reviewed in this article.

Objective To explore the correlation between renal damage of patients with gestational diabetes mellitus (GDM ) and level of serum cystatin C(Cys C) .Methods Eutocia puerperas with single birth in this center from January 2011 to December 2012 were retrospectively analyzed .400 puerperas ,who were confirmed as GDM by oral glucose tolerance test (OGTT) detection ,were collected .Among them ,200 puerperas with 24 h urinary protein content more than 0 .15 g during their 30 to 40 weeks of pregnancy were served as GDM group ,while another 200 puerperas with those not more than 0 .15 g as GDM control group .200 healthy puer-peras without GDM were served as the normal group .Serum uric acid ,creatinine ,urea ,Cys C and 24 h urinary protein content of them during their 30 to 40 weeks of pregnancy were detected .Results Serum uric acid and Cys C of patients in GDM group were obviously higher than those in the GDM control group(P<0 .05) ,while the differences of serum urea ,creatinine between the two groups showed no statistical significance (P>0 .05) .24 h urinary protein content was positively correlated with the serum uric acid and Cys C(r=0 .715 ,0 .863 ,P<0 .05) ,and had no correlation with urea and creatinine (P>0 .05) .Conclusion Serum Cys C may be used as indicators for early diagnosis and monitoring of renal damage in patients with GDM .

ObjectivesTo investigate the composition of clinical classiifcation and pathological patterns and their rela-tionships and change in children with renal disease undergoing biopsy.MethodsA retrospective analysis of pathological and clinical data obtained from children (≤14 year) with renal disease undergoing biopsy from 1984-1997 and from 1998-2011 was performed.ResultsOne thousand four hundred and sixty-two children underwent renal biopsy in 28 years, and 1313 patients were recruited in this study, 824 males (62.8%) and 489 females (37.2%). The mean age was 9 years and 4 months at renal biopsy. There were 921 children (70.1%) with primary glomerular disease (PGD) and 312 children (23.8%) with secondary glomerular disease (SDG). The main clinical classiifcations of PGD were nephrotic syndrome (NS, 31.2%), isolated hematuria (IH, 16.1%), and acute glomerulonephritis (AGN, 11.0%). The main pathological patterns of PGD were IgA nephrop-athy (IgAN, 27.6%), minimal change disease (MCD, 24.0%), and mesangial proliferative glomerulonephritis (MsPGN, 16.9%). The main causes of SGD were lupus nephritis (LN, 40.7%), Henoch-Sch?nlein purpura nephritis (HSPN, 34.3%), and hepatitis B virus related glomerulonephritis (HBV-GN, 19.6%). In this 28 years, the composition of PGD was decreased, however, the compositions of SGD and other renal diseases were increased. Compared with 1984-1997, the pathological manifestations of IgAN, MCD and focal segmental glomeralosclerosis were increased, MsPGN, IgMN, and crescentic glomerulonephritis were decreased in 1998-2011. The difference was statistically significant (P<0.05). In SGD patients, HBV-GN was significantly decreased (P<0.05).ConclusionsPGD is the main disease in children undergoing renal biopsy. IgAN is the most common pathological pattern. NS is the most common clinical classiifcation. In this 28 years, the composition of PGD is decreased, SGD and other renal diseases are increased in children undergoing renal biopsy.
