ABSTRACT

Rapid palatal expansion (RPE) is commonly used to correct transverse maxillary deficiencies and recognized as a reliable orthopedic procedure in children and adolescents. For adults, however, conventional RPE has been considered rarely successful and can produce undesirable dental effects. Along with the development of digital techniques and mini-implant anchorage, a novel method called miniscrew-assisted RPE (MARPE) has become available for the treatment of maxillary transverse deficiency in older patients recently. In this article, the biomechanical principles and indications of MARPE, the advances in device design, the clinical effects, the matters needing attention and limitations of this method, and the stability after expansion are discussed.

ABSTRACT

Retinal vein occlusion (RVO) is a vascular disease characterized by intraretinal hemorrhage,edema and hard exudation,which is caused by increased retinal vein pressure.OCT angiography (OCTA) has been widely used in the diagnosis of retinal vascular diseases including RVO by virtue of non-invasive,high resolution and stratified display of superficial,deep retinal vessels and quantification of retinal vessel density and non-perfusion area size.OCTA can provide information of retinal microvascular structure and blood perfusion under the condition of disease,it also can be used to evaluate the effect of treatment and changes of retinal circulation during the course of disease follow-up.Although OCTA cannot replace fundus angiography completely,it has brought us more information about the pathogenesis,disease progression and prognostic factors of RVO.It is believed that with the progress of technology,OCTA will bring us a new chapter in the study of retinal vascular diseases including RVO.

ABSTRACT

Objective To explore the relationship between different smoking status and hypothyroidism in six iodine-suitable areas of China. Methods A total of 8187 residents were investigated by cluster sampling in six cities, and 7448 residents were included in the survey. The height, weight, waist circumference, and blood pressure were measured by filling out epidemiological questionnaire. Blood samples were collected to detect thyroid stimulating hormone ( TSH) , thyroid peroxidase antibody ( TPOAb) , and thyroglobulin antibody ( TgAb) . Results The mean TSH, TPOAb, and TgAb positive rates in passive smoking and active smoking groups were all lower than those in non-smoking group ( all P<0.01) . In the active smoking group, the TSH value decreased by 0.023 units for every unit increase in smoking index. The positive rates of TgAb and TPOAb in both passive smoking and active smoking groups were lower than those in non-smoking group (all P<0.01). Active and passive smoking reduced the prevalence of hypothyroidism (both P<0.01). Among women, the risks of clinical hypothyroidism and subclinical hypothyroidism were reduced in both active and passive smoking groups. Besides, the risk of subclinical hypothyroidism decreased significantly when the smoking index was more than 70. In male population, the risk of subclinical hypothyroidism in active and passive smoking group decreased. Besides, the risk of clinical hypothyroidism and subclinical hypothyroidism decreased significantly when the smoking index was more than 70. Conclusion Smoking in iodine-suitable areas may reduce TSH level and the positive rates of TPOAb and TgAb.

ABSTRACT

Sonic Hedgehog (SHH) signaling pathway participates in the regulation of various organs and growth of tissue cells, maintains normal function and structure in the development of embryogenesis, however, SHH signaling pathway is in a state of inhibition. Meanwhile, the abnormal regulation of SHH signaling pathway plays an important role in the occurrence, development and drug resistance of leukemia. The mechanism of SHH signaling pathway in leukemia is similar to the solid tumor. With the further understanding of SHH signaling pathway, there are many antitumor drugs targeting SHH signaling pathway. The targeting inhibitors targeted SHH signaling pathway will become a new method for the treatment of leukemia. This paper reviews the application of the inhibitors targeting SHH signaling pathway in leukemia.

ABSTRACT

Bone marrow adipose tissue (MAT) is formed by the accumulation of adipocytes in the bone marrow cavity. Previously, the function of MAT is mainly considered to be filled with bone marrow cavity for the mechanical support. However,with the in-depth study of MAT,it has been gradually understood that MAT is not only a part of the bone marrow microenvironment,may also be a new endocrine "organ". The main component of bone marrow adipocytes(BMA) plays a regulatory role in bone marrow and systemic metabolism through the autocrine and paracrine secretion of adiponectin, leptin, interleukin-6, and a series of cytokines. Though its biological characteristics are somewhat similar with white fat adipose tissue(WAT) and brown adipose tissue(BAT),there are some significant differences,so MAT is thought to be a special adipose tissue. MAT is also involved in the development of hematological diseases,metabolic diseases,degenerative diseases,and may affect their outcomes. MAT may be the auxiliary diagnostic criteria and treatment targets of such diseases. This article will review the MAT's own biological characteristics,the differences and associations among three types of adipose tissue and the link between MAT and the diseases,which aims to explore the new research direction through the profound understanding of MAT.

ABSTRACT

Objective To investigate the prevalence of dyslipidemia and the relationship between breakfast frequency and dyslipidemia in residents over 40 years old in Yiling area of Yichang City in Hubei Province. Methods A random sampling was conducted, and 10 420 inhabitants were investigated during 2011 to 2012. Results The morbidity of dyslipidemia was 64. 0%. It was significantly higher in female than in male (65. 9% vs 60. 6%). Compared with regular breakfast eaters, non-breakfast eaters had significantly higher morbidity of higher blood low density lipoprotein-cholesterol(LDL-C) and hypertriglyceridemia(P<0. 05). The risk of elevated serum LDL-C was higher in the non-breakfast eaters group(OR=2. 382, 95%CI 1. 300-4. 367, P=0. 019) after adjusted by age, sex, smoking, drinking, etc. Conclusions Compared with regular breakfast eaters, breakfast skippers had significantly higher morbidity of dyslipidemia. Eating breakfast on daily basis may have a significant protective effect on preventing dyslipidemia.

ABSTRACT

MicroRNAs (miRNAs) are small endogenous non-coding RNA molecules.They regulate negatively the expression of target genes at post-transcriptional stages by means of affecting the stability of target mRNA or interfering with the transcriptional process.Recently,there is evidence demonstrating that miRNAs play important roles in the gene expressions of thyrotoxic heart diseases.Elevated levels of thyroid hormones profoundly influence the cardiovascular system through the renin-angiotensin system (RAS).As a principal active component of RAS,angiotensin Ⅱ receptor 1 (AT1 R) interacts with miRNAs in promoting or extenuating the progress of thyrotoxic heart disease.In this article,the roles of AT1R-associated miRNAs,miR-21,miR-155,miR-208a/b,and miR-499 in thyrotoxic heart disease were reviewed.

ABSTRACT

Two γ-glutamyl-cysteine peptides (γ-GCPs ) , ( SC2 RC7 )-γ-L-glutamyl-S-allyl-L-cysteine ( 1 ) and ( SC2 RC7 )-γ-L-glutamyl-S-propyl-L-cysteine ( 2 ) have been isolated from fresh garlic scales using ion-exchange chromatography and pre-HPLC. Their molecular structures were identified by HPLC-MS, CD, 1 H NMR, 13 C NMR, specific rotation and confirmed by the corresponding standard compounds. The influence of exogenously adding 1 and 2 on the bioavailability of iron and zinc from food legume was examined with soybean and mung bean, in the level of 0. 01 mmol/5 g of legume respectively. The enhancing effect of the two γ-GCPs of compound 1 and 2 on bioaccessibility of iron was generally evidenced in the case of soybean ( from 1 . 88% to 6 . 73% and 4 . 42%) and mung bean ( from 2 . 52% to 12 . 04% and 9 . 38%) . The two γ-GCPs similarly enhanced the bioaccessibility of zinc from the food legume, in soybean ranging from 13. 37% to 23. 95% and 20. 58%, and in mung bean from 15. 98% to 28. 44% and 27. 05%. Thus, both compounds 1 and 2 obviously had a promoting influence on the bioavailability of iron and zinc from food legumes. These findings are of practical value in a food-based strategy to enhance the bioavailability of trace minerals for human health.
