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.
2. Progress of image-guided physical ablation and percutaneous cementoplasty for bone metastatic pain
Chinese Journal of Interventional Imaging and Therapy 2019;16(2):121-124
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.

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.

Objective:To optimize the extraction process of Xiaoyan granules. Methods:The extraction process was optimized by orthogonal test with water volume, extraction times and extraction duration as the influencing factors. The dry extract rate and esculetin content were used as the evaluation indices. The dry extract rate was determined by drying method, and esculetin was determined by HPLC. 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.

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.

Objective To investigate the risk factors of surgical site infection ( SSI) in adult patients undergoing major heart surgery, and to provide the reference of controlling the development of SSI. Methods A case-control study was conducted with 54 SSI patients underwent major heart surgery from January 2001 to December 2009 in the case group and 162 controls in the control group. Univariate and multivariate conditional logistic regression analysis were used to analyse the risk factors of SSI development Results Univariate conditional logistic regression showed the risk factors for the development of SSI were left ventricular ejection fraction ( LVEF) < 50% (odds ratio ( OR) = 2.134,95% C/: 1.095 - 4. 159, P = 0. 026) , heart function New York Heart Association classification (NYHA) ≥Ⅲ grade, (OR =2. 390,95% CI: 1. 218 -4. 690; P = 0. 011) .diabetes (OR=3.275, 95% CI: 1.391 - 7. 708; P = 0.007), chronic obstructive pulmonary disease (COPD) ( OR = 5. 408,95% CI: 1.248- 23.445,P = 0.024),extracorporeal circulation time>90 mins ( OR =3. 045,95% CI: 1.540 - 6.024, P = 0. 001 ) , operation time > 4 h ( OR = 3. 281, 95% CI: 1. 610 - 6. 685, P = 0.001 ) , blood product consumption >2 u ( OR = 1. 929,95% CI; 1. 018 -3. 675;P =0. 044) .incision continuous suture close ( OR = 2.344,95%CI: 1.221 -4.498;P =0.010) exploration for bleeding (OR =6. 625,95%CI: 1.597-27.491 ;P =0. 009) , postoperative hyperglycemia (OR = 3. 510,95%CI:l. 5% -7. 718;P =0. 002) ,the stay in intensive care units (ICU) > 72 h ( OR = 3. 281,95% CI: 1. 505 - 7. 150;P = 0. 003). Multivariate analysis showed 3 variables increased with the risk of SSI: operation time >4h (OR = 3. 100,95% CI: 1.470 - 6. 537,P = 0.003 ) , incision continuous suture close (OR =2. 340,95% CI: 1. 183 - 4. 692, P = 0. 015 ) , and postoperative hyperglycemia (OR = 3. 272,95% CI:1.427 -7. 505,P=0. 005 ). Conclusions This study shows that the operation time >4 h, incision continuous suture close and postoperative hyperglycemia are risk factors most likely associated with SSI development in major heart surgery.
