Objective To investigate the clinicopathological characteristics of papillary thyroid carcinoma (PTC), and analyze their relationship with lymph node metastasis (LNM). Methods The clinicopathological data of 914 cases of PTC from January 2012 to December 2016 was analyzed retrospectively byχ2 test andχ2 trend test, including age, gender, tumor size, the number of lesions and LNM, in order to illuminate the characteristics of incidence and variation trend of PTC. Results The numbers of PTC cases in Shanxi Dayi Hospital increased year by year in recent 5 years (χ2=64.009, P=0.001). The rate of LNM was higher in age of ≤40 years old [34.9 % (84/241)] and > 70 years old [44.0 % (11/25)] than age 41-70 years old [15.6 % (101/648)] (χ2 = 39.577 and 14.009, both P= 0.000). It showed a triphasic pattern, which presented a uptrend with age decreasing in patients ≤ 40 years old (χ2= 10.490, P= 0.010), on the contrary, it appeared a rising trend with age increasing in patients>40 years old (χ2=10.170, P=0.010). The sex ratio of male and female was 1:2.97. The rate of LNM for male was higher than female (χ2=5.845, P=0.013). There was approximate risk of LNM between tumor diameter ≤1 cm and>1 cm (χ2=0.070, P=0.610). The rate of LNM in the cases of multiple lesions was apparently higher than that in cases of single lesions (χ2=145.440, P=0.000). Conclusions The incidence of PTC is on the rise. The risk factors of LNM are age (≤40 years old and>70 years old), male and multiple lesions.

BACKGROUND:Currently, human umbilical cord derived-mesenchymal stem cel s are mainly for local transplantation, which has some shortcomings, such as large trauma, bleeding, complications, that limit its widespread application in clinical practice. OBJECTIVE:To investigate the feasibility of intravenous transplantation of human umbilical cord derived-mesenchymal stem cel s for repair of spinal cord injury. METHODS:Eighty Wistar rats with spinal cord hitting were divided into five groups:blank control group with no transplantation (n=10), DMEM local transplantation group (n=15), DMEM intravenous transplantation group (n=15), cel local transplantation group (n=20), cel intravenous transplantation group (n=20). The functional recovery of spinal cord injury was observed with Basso, Beattie and Bresnahan scores at regular time as wel as hematoxylin-eosin staining and immunohistochemistry staining. RESULTS AND CONCLUSION:During 1 day to 2 weeks after transplantation, there was no significant difference in the Basso, Beattie and Bresnahan scores between the five groups;within 4-12 weeks after transplantation, the Basso, Beattie and Bresnahan scores were significantly higher in the two cel transplantation groups than the other three groups, but there was no difference between these two cel transplantation groups (P>0.05). Histological observation showed that the number of voids and glial scars was less in the cel local transplantation group and cel intravenous transplantation group compared with the other three groups, and there was also no difference between the two cel transplantation groups. These results indicate that the intravenous transplantation of human umbilical cord derived-mesenchymal stem cel s is similar to the local transplantation in the repair of acute spinal cord injury, which is simple and avoids secondary injuries and various complications. It is recommended that this method provide a new approach for cel transplantation.

Objective To evaluate the feasibility and significance of CT image-based threedimensional (3D) brachytherapy for cervical cancer.Methods Three-dimensional (3D) plan and twodimensional (2D) plan were designed for 55 CT images of brachytherapy from 12 cervical cancer patients who received radical radiotherapy in 2013.Dosimetric comparison was performed between the 3D plan and 2D plan,and paired t-test,Wilcoxon signed rank test,Pearson correlation analysis,and Spearman correlation analysis were performed.Results A point dose,D90,V100,CI,and CI' in 3D plan were higher than those in 2D plan (P=0.015,0.016,0.000,0.000,0.000).Bladder point dose,rectal point dose,and rectal D2 cm3 in 3D plan were slightly higher than those in 2D plan,but hot spot dose was significantly reduced in 3D plan (P =0.140,0.123,0.214).Bladder D2cm3 was significantly higher than bladder point dose (P =0.000).Sigmoid colon D2cm3 was more correlated with the average doses of the three highest rectal points than rectal D2 cm3 (r =0.314,0.630,P =0.000,0.000).V100 showed a linear relationship with high-risk CTV (r =0.981,P =0.000).Bladder D2cm3 was higher than 430 cGy when the bladder volume was more than 80 cm3 ;small intestinal D2 cm3 did not change significantly when the bladder volume was less than 115 cm3,but decreased significantly once the volume exceeded the value.Conclusions Compared with the traditional 2D plan,the 3D plan for CT image-based cervical cancer brachytherapy significantly increases the target coverage and conformity index,but does not significantly increase the doses to organs at risk.Point dose evaluation is confirmed to be inaccurate.The doses to the bladder,rectum,and small intestine can be adjusted by controlling the bladder volume.

Objective:To investigate the roles and regulation mechanism of miR-31 in human cutaneous squamous cell carcino-ma (cSCC) growth. Methods:cSCC cells were transfected with the antisense oligonucleotide (ASO) of miR-31, and the cSCC growth was tested by colony formation and in vivo tumor formation assays. The target gene of miR-31 was validated by Western blot and green fluorescent protein (GFP) reporter assay. The cells were then transfected with the siRNA of the target gene, and the effect of the target gene on cell growth was preformed by colony formation assay. Finally, real-time PCR and immunohistochemistry were used for analy-sis of the expression of miR-31 and its target gene. Results:miR-31 ASO resulted in a low number of cell colonies and small tumor vol-ume (P<0.05). Western blot showed that the cells with miR-31 ASO had a higher protein level of large tumor suppressor homolog 2 (LATS2) than the control. The 3' UTR of LATS2 had a binding site with miR-31, and miR-31 ASO increased the GFP intensity con-trolled by LATS2 3' UTR, whereas no effect was observed on the mutant LATS2 3' UTR. Western blot showed that LATS2 siRNA inhib-ited the expression of LATS2 protein by about 80%. Knocking down of LATS2 increased the colony number by about 70%or 1.3-fold in cSCC cells. Real-time PCR showed that miR-31 was overexpressed in most cSCC tissues, compared with normal tissues. An inverse relationship existed between miR-31 and LATS2 expression levels. Immunohistochemistry validated that LATS2 was downregulated in cSCC tissues. Conclusion:miR-31, which functions as an oncogene, promotes cSCC growth by suppressing LATS2 expression. Our da-ta suggest that miR-31 is a potential miRNA-based therapeutic target for cSCC growth.
