ABSTRACT
Objective:To investigate the diagnostic value of microRNA-19(miR-19)and microRNA-21(miR-21)in elderly patients with differentiated thyroid carcinoma(DTC), and to analyze the relationship of miR-19 and miR-21 expression with pathological characteristics in elderly patients with DTC.Methods:A total of ninety-six elderly DTC patients visiting our hospital from January 2015 to January 2018 were included in this retrospective study.They underwent cervical lymph node puncture biopsy and radical surgery for thyroid cancer.The expression levels of miR-21 and miR-19 were detected in lymph node tissues, thyroid cancer tissues and normal para-cancerous tissue.The differences in miR-21 and miR-19 expression levels between three different pathological tissues in elderly patients were analyzed.The correlation of miR-21 and miR-19 expression levels with different clinico-pathological features in elderly patients was observed.Results:The expression levels of miR-21 from low to high were(0.92±0.33)in para-cancerous tissue, (3.41±0.64)in lymph node tissue and(4.28±1.56)in DTC tissue respectively( F=296.683, P<0.01), the difference was statistically significant( F=296.683, P=0.01). While, there was no significant difference in the expression levels of miR-19 among different tissues( P>0.05). Spearman correlation test showed that the expression level miR-21 in DTC tissue was positively correlated with that in lymph node tissue and para-cancerous tissue( r values were 0.724, 0.801, all P<0.01), while the expression level of miR-19 showed no correlation of DTC tissues with lymph node and para-cancerous tissues( r=0.127 and 0.165, P>0.05). The expression level of miR-21 in lymph node tissue was positively correlated with that in para-cancerous tissues( r=0.705, P<0.01), but the expression level of microRNA-19 had no correlation between the two kinds of tissues( r=0.191, P>0.05). There was no significant difference in the expression of miR-21 in cervical lymph nodes among patients with different gender and tumor diameter( P>0.05). The expression level of miR-21 in cervical lymph nodes was significantly higher in stage Ⅲ patients than in stage Ⅰ-Ⅱ patients( P<0.05). The expression level of microRNA-21 in cervical lymph nodes was higher in patients with extra-glandular infiltration than without extra-glandular infiltration( P<0.05). The expression of microRNA-19 in cervical lymph nodes showed no significant difference regardless of sex, tumor diameter, tumor stage, extra-thyroid invasion. Conclusions:MiR-19 may not be involved in the development of DTC in elderly patients, and microRNA-21 may play an important role in the development of DTC in elderly patients, especially in the process of tumor invasion and metastasis.Early cervical lymph node puncture for miR-21 detection helps early diagnose and evaluate DTC, to provide a basis for the choice of treatment options.
ABSTRACT
Objective To research the expression of mitofusin-2 (mfn2) and tumor metastasis suppressor genes (nm23)in bladder cancer cells and its correlation with clinical pathological feature. Methods Immunohistochemistry was used to measure the expression of mfn2 and nm23.Sixty-five cases of bladder cancer were sampled,which include fif-ty cases of male and fifteen cases of female. TNM stage:Forty-seven cases were in stage I;Ten cases were in stage II; Five cases were in stageⅢ; Three cases were in stageⅣ. Other fifteen cases were sampled from normal bladder or benign tumor of bladder as control . All cases were collected from department of pathology,affiliated Hospital of hebei union university. Results The positive expression rate of mfn2 in bladder cancer tissues was significantly higher than those in normal blad-der tissues and benign tumor of bladder(χ2=32.528,P<0.05);The positive expression rate of nm23 in bladder cancer tis-sues was significantly lower than those in normal bladder tissues and benign tumor of bladder (χ2=19.719,P<0.05);the high expression level of mfn2 in bladder cancer was associated with tumor differentiation and TNM stage(P<0.05),but not corre-lated with age,sex,lymph node metastasis and clinical grade. The low level of nm23 was associated with TNM stage,clinical grade and LN metastasis. Conclusion The positive expression rate of mfn2 was increased in bladder cancer. It indicated that there was a close relationship between mfn2 and the occurrence and development of bladder cancer;The expression rate of nm23 was decreased in bladder cancer,it may be a predictor for metastasis and prognosis of bladder cancer.
ABSTRACT
Objective To analyze relationship between elderly patients with acute cerebral infarction hyponatremia and their nutrition status.Methods One hundred and twenty patients were selected who hospitalized from January 2011 to December 2012.All the patiens' fasting venous blood samples were taken in the next day morning after hospitalied.and then performed the routine blood test,blood biochemical testing items,observed the level of serum sodium (Na),hemoglobin (Hb),total protein (TP),serum albumin (ALB),prealbumin (PA),C-reactive protein (CRP) and lymphatic cell counts (LY) were measured.According to the value of serum sodium,all patients were classified to lower sodium group (serum sodium ＜ 135 mmol/L,36cases),normal group (serum sodium range from 136 to 145 mmol/L,76 cases),and higher sodium group (serum sodium ＞ 145 mmol/L,8 cases).The results were statistically analyzed.Results The incidence of hyponatremia was 30％ (36/120).The levels of TP,ALB,PA,Hb and LY in lower sodium group were (50.35 ± 8.61) g/L,(28.35 ± 6.98) g/L,(89.96 ± 12.13) mg/L,(94.13 ± 25.36) g/L and (0.87 ±0.51) × 109 respectively,lower than that of normal group ((65.30 ± 5.48) g/L,(37.50 ± 3.63) g/L,(178.14 ± 18.61) mg/L,(124.87 ± 29.08) g/L,(1.67 ± 0.98) × 109 respectively,t =5.0897,7.1058,4.3216,3.8174,5.4237 respectively,P ＜ 0.01),but the level of CRP ((76.55 ± 49.95) mg/L) in lower sodium group was obviously higher than the normal serum sodium group ((21.33 ±35.04) mg/L,t =0.1287,P ＜ 0.01).The level of the serum sodium in ICU was related to the TP,ALB,PA,Hb and CRP(r =0.3176,0.4369,0.3695,0.2408,0.3612,0.0753 respectively,P ＜0.05).Conclusion The level of the merger of hyponatremia was correlated with malnutrition in the elderly acute cerebral infarction patients in ICU.We must strengthen the nutrition support treatment while correcting hyponatremia,in order to improve the clinical curative effect.
ABSTRACT
Objective:To investigate the expressions of Mfn2(mitofusin 2) in non-small-cell lung cancer (NSCLC) tissues and non-cancerous lung tissues,and analyze its relationship with clinicopathological characteristics of lung carcinomas.Methods:The expressions of Mfn2 mRNA and protein in 92 cases of NSCLC tissues and 27 cases of non-cancerous lung tissues were detected by in situ hybridization and immunohistochemical methods. Results:The positive rates of Mfn2 mRNA and protein in pulmonary squamous cell carcinoma were higher than those in adenocarcinoma (83.33% and 89.58% vs 56.82% and 65.91%), respectively. The positive rates of Mfn2 mRNA and protein in NSCLC were higher than those in the non-cancerous lung tissues (25.93% and 29.63%) . The difference was statistically significant among the three groups (P0.05). The expression of Mfn2 mRNA was consistent with that of Mfn2 protein in NSCLC.Conclusion:Mfn2 was involved in the initiation and progression of lung cancer, and the expression of Mfn2 was related to the histological types of lung cancer and its differentiation degree.
