ABSTRACT

ABSTRACT Introduction Regular physical activity helps improve cardiovascular and cerebrovascular skills. How to evaluate the nervous tension of the cardiovascular and cerebrovascular vessels through sports is a hot topic. Objective The paper discusses the influence of regular participation in sports on people's cardiovascular function and blood-related indicators. Methods We select 30 healthy older adults who regularly participate in sports, record their ECG changes, blood pressure, heart rate and other related cardiovascular function indicators, and analyze the blood function of the elderly. Detection of blood cell count (RBC), red blood cell volume (MCV) and hemoglobin (Hb), serum creatinine (Cr), blood glucose (BGS), triglycerides (TG), cholesterol (TC), low-density lipoprotein (LDL) and high-Density lipoprotein (HDL) is measured. Results Older adults who persist in exercise for a long time have better indicators than those who do not exercise. Conclusions Appropriate aerobic exercise can reduce the stiffness of blood vessels in the elderly. Exercise can help the elderly increase heart rate variability and improve the heart's autonomic nerve function's blood indicators, and body mass.

ABSTRACT

@#[摘 要] 目的:探讨miR-125a-5p通过调控Bcl-2相关永生基因4(Bcl-2-associated athanogene 4,BAG4)的表达抑制胃癌细胞迁移和侵袭的分子机制。方法:选用2014年1月至2015年12月兰州大学第一医院手术切除的82例胃癌组织标本及配对的癌旁组织以及人胃癌细胞系MGC803、BGC823、SGC7901、HGC27及人胃黏膜上皮细胞(GES-1),qPCR法检测胃癌组织、癌旁组织及胃癌细胞系中miR-125a-5p的表达水平。分别将miR-125a-5p mimic、miR-125a-5p inhibitor、(si-BAG4)siRNA-BAG4及阴性对照质粒转染至胃癌细胞,划痕愈合实验和Transwell侵袭实验分别检测miR-125a-5p/BAG4信号轴对胃癌细胞迁移和侵袭能力的影响。WB检测胃癌细胞中BAG4蛋白的表达。荧光素酶报告基因实验验证miR-125a-5p和BAG4之间的靶向调控关系。结果:miR-125a-5p在胃癌组织和细胞系中均低表达(均P<0.01)。miR-125a-5p的表达与患者的性别(P=0.953)、年龄(P=0.772)、肿瘤部位(P=0.867)、组织学分级(P=0.745)和肿瘤大小(P=0.088)无相关性,与胃癌患者的T分期(P=0.003)、N分期(P=0.001)、M分期(P=0.027)和TNM分期(P=0.035)显著相关,差异有统计学意义。miR-125a-5p低表达是胃癌患者总生存时间的独立危险因素。过表达miR-125a-5p显著抑制胃癌细胞的迁移和侵袭能力(均P<0.01)。敲降BAG4可逆转miR-125a-5p inhibitor对胃癌细胞迁移和侵袭能力的抑制作用。荧光素酶报告基因实验证实miR-125a-5p可与BAG4 3'非翻译区(untranslated regions,UTR)结合抑制其表达。结论:miR-125a-5p通过靶向下调BAG4的表达水平进而抑制胃癌细胞的迁移和侵袭。

ABSTRACT

Objective To detect 715 bp sequence of 28S rRNA in sarcosaphagous flies, and to identify their common species for solving the problem of morphological identification, as well as providing technical support for postmortem interval (PMI) estimation. Methods Twenty-nine common sarcosaphagous flies were collected in Luoyang and classified by morphological characteristics. The DNA was extracted from the fly's legs by Chelex-100 method and then the fragments of 28S rRNA were amplified and sequenced. The results were compared with twenty-eight corresponding fly species of GenBank and EMBL databases. All the sequences were analyzed by MEGA7.0 software, and sequence alignment was performed by the searching in BLAST. The nucleotide composition was analysed, and the intraspecific and interspecific ge-netic distance and phylogenetic tree were established. Results Twenty-nine sarcosaphagous flies were classified into 6 species of 5 genera, 3 families by morphological characteristics. In the obtained 715 bp sequence of 28S rRNA , the comparison result of online BLAST showed that the similarity was 100%. Five species were well clustered by a phylogenetic tree. Between different groups, the interspecific and intraspecific differences ranged from 0.007 to 0.045 and 0 to 0.001, respectively. Conclusion The 28S rRNA target gene sequences shows a good identification capability, which can be a new genetic marker for the identification of sarcosaphagous flies.

ABSTRACT

The VEGF in low oxygen conditions are reported to prolong the survival of malignant cell, and thus this gene has a critical role in tumor growth and invasion as well as development of malignant tumor. We aimed to assess the association between the six common SNPs and the risk of osteosarcoma, and their association with environmental factors. 176 subjects with osteosarcoma and 176 gender- and sex-matched healthy control individuals were enrolled into our study. The VEGF -2578C/A, -1156G/A, +1612G/A, +936C/T, -634G/C and -460T/C gene polymorphisms were determined using a polymerase chain reaction-restriction fragment length polymorphism [PCR-RFLP] assay according to manufacturer's instructions By conditional logistic regression analysis, AA and CA+AA genotypes of VEGF -2578C/A were associated with significant increased risk of osteosarcoma compared with CC genotype, and the ORs [95%CI] were 2.32 [1.18-4.60] and 1.68 [1.07-2.64], respectively. Moreover, individuals with CC and TC+CC genotypes of VEGF-460T/C had significant increased risk of osteosarcoma compared with those carrying with the TT genotype, and ORs [95%CI] were 2.15 [1.10-4.21] and 1.60 [1.0-2.58], respectively. By stratified analysis, we did not find statistically significant associated between VEGF -2578C/A and -460T/C gene polymorphisms and cancer risk by stratification analysis. Our results suggested that VEGF -2578C/A and -460T/C gene polymorphisms may be association with an increased risk of osteosarcoma

ABSTRACT

This study aims to investigate the effects of fibroblast growth factor 21 (FGF-21) on learning and memory abilities and antioxidant capacity of D-galactose-induced aging mice. Kunming mice (37.1 +/- 0.62) g were randomly divided into normal control group, model group and FGF-21 high, medium and low dose groups (n = 8). Each group was injected in cervical part subcutaneously with D-galactose 180 mg x kg(-1) x d(-1) once a day for 8 weeks. At the same time, FGF-21-treated mice were administered with FGF-21 by giving subcutaneous injection in cervical part at the daily doses of 5, 2 and 1 mg x kg(-1) x d(-1). The normal control group was given with normal saline by subcutaneous injection in cervical part. At seventh week of the experiment, the learning and memory abilities of mice were determined by water maze and jumping stand tests. At the end of the experiment, the mice were sacrificed and the cells damage of hippocampus was observed by HE staining in each group. Reactive oxygen species (ROS), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and total antioxidant capacity (T-AOC) in the brain of mice were determined. The results showed that different doses of FGF-21 could reduce the time reaching the end (P < 0.01 or P < 0.05) and the number of touching blind side (P < 0.01 or P < 0.05) in the water maze comparing with the model group. It could also prolong the latency time (P < 0.05) and decrease the number of errors (P < 0.01 or P < 0.05) in the step down test. The result of HE staining showed that FGF-21 could significantly reduce brain cell damage in the hippocampus. The ROS and MDA levels of three different doses FGF-21 treatment group reduced significantly than that of the model group [(5.58 +/- 1.07), (7.78 +/- 1.92), (9.03 +/- 1.77) vs (12.75 +/- 2.02) pmol (DCF) x min(-1) x mg(-1), P < 0.01 or P < 0.05], [(2.92 +/- 0.71), (4.21 +/- 0.81), (4.41 +/- 0.97) vs (5.62 +/- 0.63) nmol x mg(-1) (protein), P < 0.01]. Comparing with the model group, the activities of SOD, GPx, CAT and T-AOC of the three different doses FGF-21 treatment groups were also improved in a dose-dependent manner. This study demonstrates that FGF-21 can ameliorate learning and memory abilities of D-galactose induced aging mice, improve the antioxidant abilities in brain tissue and delay brain aging. This finding provides a theoretical support for clinical application of FGF-21 as a novel therapeutics for preventing aging.

ABSTRACT

Stain identification has long been a task in forensic biology. The identification of semen stain, one of the most common human stains, can provide crucial information for crime scene reconstruction and forensic investigation. Traditional detection of semen stain depends largely on the microscopic identification of spermatozoa, enzyme activity-based methods or antigen-antibody reactions. These morphological, proteinological and zymological approaches, however, are apparently inadequate in identifying tiny, admixed, degraded or contaminated samples. With the development of transcriptomics and epigenetics, many semen-specific mRNA markers, such as protamine-1 (PRM1) and -2 (PRM2), have been applied to semen and semen stain identification. Messenger RNA profiling shows great promise in identifying tissues as demonstrated by the recognition of specific markers. Further more, studies on tis-sue-specific differential DNA methylation will provide a scrumptious way of identifying difficult samples.

ABSTRACT

Deep venous thrombosis (DVT) is initiated intraoperatively and may display symptoms postopera- tively following total hip or total knee arthroplasties. Pulmonary embolism (PE) and DVT cause morbidity and mortality. It has been established that patients who undergo a major lower-extremity joint replacement should receive prophylaxis due to the increased risk of DVT. Despite use of thrombo-prophylaxis, elective replacement surgery carries a high risk of venous thromboembolic complications. The early detection of DVT and treatment with systemic anticoagulation to pre- vent DVT are essential in the management of patients undergoing total joint arthroplasty. Extended medical throm- bo-prophylaxis is indicated for some high-risk patients. Routine postoperative duplex surveillance for DVT may be clinically useful. In the early post-operative phase, combined prophylaxis such as low-molecular-weight heparins and mechanical methods may be more effective than single intervention measures. However, the efficacy and safety of an- ticoagulation therapy, using various medicines administered after total arthroplasty of large joints are still undetermined and controversial.We should also be alert to the frequency and extent of postoperative hematomas. There are still many uncertainties in treatments to prevent DVT in terms of safety and cost-effectiveness. Therefore, prospective, ran- domised, controlled and multicenter studies may be necessary to obtain valuable information according to evidence based medicine.
