Non-small cell lung cancer (NSCLC) is a type of lung cancer which has a high mortality and low survival rate. Previous studies have revealed that long non-coding RNAs participate in tumorigenesis and metastasis in NSCLC. In the present study, the function of small nucleolar RNA host gene 12 (SNHG12) was investigated in NSCLC. Using reverse transcription-quantitative polymerase chain reaction analysis, it was identified that SNHG12 was significantly overexpressed in NSCLC specimens. Furthermore, overexpression of SNHG12 was identified to be associated with tumor progression and poor overall survival rates. Knockdown of SNHG12 in NSCLC cells could effectively induce cell apoptosis and suppress cell viability, proliferation, migration and invasion via inhibition of the epithelial-mesenchymal transition process. Furthermore, a direct interaction between microRNA (miR)-218 and the binding site of SNHG12 was identified. SNHG12 acted as an endogenous sponge for miR-218. Knockdown of SNHG12 upregulated the expression level of miR-218 as well as downregulating the Slug/zinc finger E-box-binding homeobox 2 EMT signaling pathway, and thus inhibited cell migration and invasion. Therefore, SNHG12 may serve as a key biomarker and a potential therapeutic target for the treatment of NSCLC.

A large proportion of young adults have insufficient TWI. Participants with lower TWI would not compensate with water from food. The variances in TWI among participants were mainly due to differences in total drinking fluids. There is an urgent need to improve the fluids intake behaviors of young adults.

Background: The purposes were to investigate the drinking patterns and hydration biomarkers among young adults with different levels of habitual total drinking fluids intake. Methods: A cross-sectional study was conducted among 159 young adults aged 18-23 years in Baoding, China. Total drinking fluids and water from food were assessed by 7-day 24-h fluid intake questionnaire and duplicate portion method, respectively. The osmolality and electrolyte concentrations of the 24 h urine and fasting blood samples were tested. Differences in LD 1 (low drinker), LD 2 , LD 3 and HD (high drinker) groups, stratified according to the quartiles of total drinking fluids, were compared using one-way ANOVA, Kruskal-Wallis H test and chi-square test. Results: A total of 156 participants (80 males and 76 females) completed the study. HD group had greater amounts of TWI (Total Water Intake), water from food, higher and lower contributions of total drinking fluids and water from food to TWI, respectively, than LD 1 , LD 2 and LD 3 groups (p < 0.05). Participants in HD group had higher amounts of water and water from dishes than participants in LD 1 , LD 2 and LD 3 groups (p < 0.05). No significant differences were found in the contributions of different fluids to total drinking fluids within the four groups (p > 0.05). The osmolality of urine was 59-143 mOsm/kg higher in LD 1 than that in LD 2 , LD 3 and HD group (p < 0.05). The percentage of participants in optimal hydration status increased from 12.8% in LD 1 group to 56.4% in HD group (p < 0.05). HD and LD 3 groups had 386~793 higher volumes of urine than that of LD 1 and LD 2 groups (p < 0.05). Differences were found in the concentrations of electrolytes among the four groups (p < 0.05). No significant differences were found in the plasma biomarkers (p > 0.05), with the exception of higher concentration of Mg in LD 3 and HD groups than

Objective: To explore the interference of monoclonal immunoglobulin (M protein) on the detection of serum LDL-C in patients with multiple myeloma, improve the understanding of this matter, determine and establish the correct method, and provide more accurate clinical results through this case. Methods: A case was selected for analysis by the direct method. Results: The interference of IgG?-type M protein on LDL-C detection could not be completely eliminated by the enzymatic method. Conclusion: IgG-type type M protein affects the detection of LDL-C by the enzymatic method; thus, light reagents can be used with the direct method for detection.
