ABSTRACT
Lung cancer is one of the most important malignant tumors in the world. The morbidity and mortality rank the first in all kinds of cancer. Long non-coding RNA (lncRNA) is at least 200 nt long and has no protein coding capacity. It plays an important role in the epigenetic regulation, cell cycle regulation, the regulation of cell differentiation, and many other life activities. The studies indicate that dysregulation of lncRNAs in non-small cell lung cancer (NSCLC) tissue and blood circulation is associated with the occurrence and development of cancer. The lncRNAs play an significant role in proliferation, differentiation, migration and apoptosis of the tumor cells. Explore the potential mechanism between lncRNAs and NSCLC is beneficial for the early diagnosis, target therpy and improve prognosis. Therefore, the study aims to demonstrate the latest studies on the lncRNAs related to occurence, diagnosis, therpy and prognosis of NSCLC. It can help to deeply understanding of lncRNA, and provide new ideas for the prevention of NSCLC.

Esophageal cancer is a common gastrointestinal malignancy and China has a high incidence of esophageal cancer. Zinc deficiency is a key risk factor for the occurrence and development of esophageal cancer and affects its progression through various ways, including changing the expression of coding genes and non-coding genes. In addition, the lack of zinc ions can also affect the stability of zinc finger protein (ZNF). The dysregulation of ZNF and its associated long non-coding RNAs (LncRNAs) play an important role in the progression of esophageal cancer. This paper summarizes the molecular relationship between zinc deficiency and esophageal cancer, hoping to provide new strategies and methods for the early diagnosis, targeted therapies and prognosis assessment of esophageal cancer.
ABSTRACT
Objective To explore the cognitive function of the patients with bipolar depression (BP), unipolar depression (UP) and their first-degree relatives.Methods 52 patients with BP and 49 their first-degree relatives ,67 patients with UP and 59 their fi~t-degree relatives, 97 normal controls were tested by information, arithmetic, digital symbol, digital span test, block design,logical memory (included immediately and delayed) , visual memory(included immediately and delayed), Stroop Test (included Stroop C and Stroop CW), trail making test (included Part A and Part B) ,verbal fluency and modified Wisconsin card sorting test(M-WCST).Results The scores of digital symbol, block design, immediately logical memory, delayed logical memory, immediately visual memory,delayed visual memory,trail making test B and WCST in the patients with BP and UP were worse than those in normal control(P＜0.01).The score of WCST in the patients with BP was lower than that in the patients with UP ((3.02± 1.96), (4.40± 1.13), P＜0.01).The score of WCST in the relatives of the patients with bipolar depression was worse than that in the normal control((4.32±1.66), (5.15±1.27), P＜ 0.05).Conclusion The patterns of impaired cognitive function on sustained attention,concept of visual space,visual memory,verbal memory and executive function are similar in the patients with BP and UP.The executive function of the patients with BP is worse than the patients with UP.
ABSTRACT
Objective To explore the executive function in clinical subtypes of attention deficit hyperac?tivity disorder( ADHD) . Methods 19 children with ADHD/ inattentive type( ADHD?I) ,13children with ADHD/hyperactive?impulsive( ADHD?HI) 33 children with ADHD/combined type ( ADHD?C ) and 30 normal children were tested by Stroop test ( included Stroop C and Stroop CW) ,modified Wisconsin card sorting test( M?WCST) , tower of Hanoi,digital span and verbal fluency. Results The scores of Stroop C and Stroop CW,digit inverse reci?ting,tower of Hanoi and WCST in the children with ADHD were worse than those in normal control((104.8±4.0), (105.9±4.2),(104.8±3.7),(104.8±4.0), P<0.05;(84.0±9.2),(84.8±7.9),(78.2±7.8),(92.2±7.1), P<0.01;(4.0±1.8),(3.7±1.2),(3.8±1.5),(5.1±1.6), P<0.01;(3.0±1.0),(3.3±1.0),(2.7±1.3),(3.8±1.3), P<0.01;(4.1±1.6),(4.2±1.9),(4.3±2.1),(5.4±1.7), P<0.05;(6.6±3.2),(6.7±2.4),(8.0±2.9),(5.3± 2.4), P<0.01;(10.2±2.8),(11.1±3.8),(12.3±4.0),(9.4±3.2), P<0.05). The scores of Stroop CW in the chil?dren with ADHD?C were worse than those in other two subtypes(P<0.01). Conclusion The executive functions of the chil?dren with ADHD are impaired,including poor response inhibition,working memory,planning and cognitive flexibility. The dysfunction of response inhibition is possible an index to discriminate the subtypes of ADHD.
ABSTRACT
Objective To optimize the matrix formulation of the extract of Chuanxiong Rhizoma cataplasm. Methods The optimal proportion of matrix formulation was selected by uniform design and response surface method. The primary adhesion force, lasting adhesion force, peel strength and residuals on the anti-sticking paper were used as test parameters. The optimal ratios of NP-700, glycinate aluminum, glycerin, tartaric acid, the concentration of drug, and the volume of drug were acquired. Results The matrix formulation of the cataplasm was made with NP-700∶glycinate aluminum∶glycerin∶tartaric acid∶concentration of drug∶volume of drug=1.1∶0.08∶7∶0.04∶4∶5. Conclusion Uniform design combined with response surface method can be used for the optimization of the matrix formulation of cataplasm. The optimal matrix prescription has higher drug-loading, with good spreadability, moisture-retention capability and adhesive force.
