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.

To investigate the effect of recombinant human growth hormone (rhGH) on JAK2-STAT3 pathway and the growth of gastric cancer cell lines at different GHR expression status, the eukaryotic expression vector targeting human GHR (pGPU6/GFP/Neo-shGHR and pGPU6/GFP/Neo-scramble) was constructed and transfected into MGC803 cells by Lipofectamine 2000. Stable expressive cell lines were obtained by G418 screening. The expression of GHR was analyzed by Western blotting. After being stimulated with rhGH, cell growth was detected by MTT assay. Cell cycle and apoptosis were examined by flow cytometry. The components of JAK2/STAT3 signaling pathway were detected by Western blotting. There is no significant difference of GHR expression between MGC803 and pGPU6/GFP/Neo-scramble-transfected cells (named as MGC803-NC) (P > 0.05). Compared with MGC803, the GHR expression in pGPU6/GFP/Neo-shGHR-transfected cells (named as MGC803-shGHR) decreased significantly (protein decreased 50%). The cells were treated with rhGH at 0, 150 and 300 ng x mL(-1), the growth rate of MGC803 and MGC803-NC increased significantly, PI and the number of G2/M phase cells all increased significantly, and apoptosis decreased significantly. Western blotting revealed that the expression of pJAK2 and pSTAT3 was up-regulated after being treated with rhGH in MGC803 and MGC803-NC cells. In contrast, similar change was not observed in MGC803-shGHR cells. Knockdown of GHR gene may decrease the sensitivity of gastric cancer cells to rhGH, and down-regulating of components of the expression of JAK2/STAT3 signaling pathway may be the potential mechanisms.

Objective:To evaluate the curative efficacy of tacrolimus (FK506)combined with corticosteroids in the treatment of idiopathic membranous nephropathy (IMN ), and to analyze the response of anti-M-type phospholipase A2 receptor (PLA2R)antibody to the treatment.Methods:Sixty-one adult IMN patients were divided into FK506 group (FK506 combined with corticosteroids,n = 24)and CTX group (cyclophosphomide combined with corticosteroids,n=37)according to their willing to the acceptance of different immunosuppressives. The remission rates of the patients at 4,8,12 and 24 weeks after treatment in two groups were analyzed.The ELISA method was used for the detection of serum anti-PLA2R antibodies of the patients before and after treatment.The antibody level changes were observed and the difference of remission rates was compared between the antibody positive patients and the negative patients in FK506 group.Results:The total remission rates of the patients in FK506 and CTX groups 24 weeks after treatment were 91.7% and 64.9% respectively and the total remission rate of the patients in FK506 group was significantly higher than that in CTX group (P < 0.05).The total remission rates at 8,12,24 week after treatment and the partial remission rates at 12 and 24 weeks in FK506 group were significantly higher than those in CTX group (P <0.05).The anti-PLA2R antibody positive rates in FK506 group and CTX group were 75.0% and 70.3%,respectively;the negative conversion rate of anti-PLA2R antibody at 24 weeks after treatment in two groups were 61.6% and 57.7%,respectively;there were no significant differences between two groups (P >0.05).The total remission rates of the antibody positive patients and negative patients at baseline in FK506 group 24 weeks after treatment were 88.9% and 100.0%,respectively;there was no significant difference (P > 0.05).Except the characteristic side effects of corticosteroids,the patients in FK506 group presented no hyperglycemia,tubulointerstitial damage,hepatic lesion or neurotoxicity. But the patients in CTX group showed mild hepatic lesion or gastrointestinal symptoms.Conclusion:The remission rate of FK506 combined with corticosteroids is higher than that of CTX combined with corticosteroids in the treatment of IMN patients.FK506 treatment has relatively rapid effect and less side effects as well.The negative conversion of serum anti-PLA2R antibody follows the remission after treatment;however,the negative conversion rate has no significant difference between FK506 group and CTX group.The remission rate of IMN patients treated with FK56 combined with hormone has no relationship with the baseline anti-PLA2R antibody.

Objective To evaluate the relationship and screening value of percentage of body fat (BF%) and waist height ratio (WHtR) for hyperlipidemia in physical examination people. Methods A total of 2 668 objects taking physical examination in Henan Province People′s Hospital from September to December 2014 were included in this study. Values of height, body mass index (BMI), waist circumference, body composition and blood lipid level were detected. The receiver oper?ating characteristic curve (ROC) was used to analyze the screening rate of WHtR and BF%on hyperlipidemia with sensitivi?ty, specific and area under the curve (AUC). After stratified by age, waist circumference and BMI, multivariable logistic re?gression analysis was used to investigate the association between hyperlipidemia risk, BF% and WHtR. Results The screening accuracy rate on hyperlipidemia was higher for BF%, AUC was 0.79 in both female and male people. Among wom?en with BMI<18.5 kg/m2 and 18.5~<24 kg/m2, the risk of hyperlipidemia was higher in superfatted group than that of normal group. There was no correlation between WHtR and hyperlipidemia. Among men older than 40 y or with abnormal waist cir?cumference (≥85 cm), the risk of hyperlipidemia was higher in superfatted group than that of normal group, but not associat?ed with WHtR. Conclusion The BF%is a better screening indicator for hyperlipidemia compared with that of WHtR and BMI. Women with BMI<18.5 kg/m2 and 18.5~<24 kg/m2 and men older than 40 y or with waist circumference over 85 cm are suggested to do body composition tests to improve screening accuracy for hyperlipidemia.
