Objective To explore the effect and complication of diode laser and long-pulsed alexandrite laser for hair removal in different skin type.Methods A total of 1061 patients (1741 sites) were divided into 2 groups by skin type:one group were treated with diode laser,with wave length of 810 nm,and pulse width of 400 ms,with 12 mm × 10 mm spot size; another group were treated with long-pulsed alexandrite laser,with wave length of 755 nm,of pulse width of 20 ms,with 12.5 mm spot size,50-60 days intermitted between each treatment.Results The effect of hair removal by two lasers in different skin type was without divergence,but to darker skin,complication was lower when treated by diode laser.Conclusions The effect of hair removal by two lasers in different skin type is similar,but diode laser on hair removal is much safer to dark skin.

There are many return-to-work measurement instruments, including return-to-work ability, return-to-work self-efficacy, readiness for return-to-work and obstacles to return-to-work. This paper reviewed the return-to-work measurement instruments, content, evaluation method, targeting group, reliability and validity of measurements, and summarized its advantages and disadvantages. It could provide reference for construction of vocational rehabilitation programs and improvement of evaluation of the effect.

Tumorigenesis involves metabolic reprogramming and abnormal lipid metabolism, which is manifested by increased endogenous fat mobilization, hypertriglyceridemia, and increased fatty acid synthesis. Fatty acid synthase (FASN) is a key enzyme for the de novo synthesis of fatty acids, and monoacylglycerol esterase (MGLL) is an important metabolic enzyme that converts triglycerides into free fatty acids. Both enzymes play an important role in lipid metabolism and are associated with tumor-related signaling pathways, the most common of which is the PI3K-AKT signaling pathway. They can also regulate the immune microenvironment, participate in epithelial-mesenchymal transition, and then regulate tumor invasion and metastasis. Current literature have shown that these two genes are abnormally expressed in many types of tumors and are highly correlated with tumor migration and invasion. This article introduces the structures and functions of FASN and MGLL, their relationship with abnormal lipid metabolism, and the mechanism of the regulation of tumor invasion and metastasis and reviews the research progress of the relationship of FASN and MGLL with tumor invasion and metastasis.

OBJECTIVETo evaluate the safety and efficacy of exercise rehabilitation in coronary heart disease patients post reascularization procedure.

METHODWe searched the Cochrane Central Register of Controlled Trials (CCRCT), Pubmed, Wanfang, CNKI, CBM and VIP database for randomized controlled trials (RCTs) on exercise rehabilitation for patients with coronary artery disease post percutaneous coronary intervention revascularization or coronary artery bypass grafting. Quality assessment and data collection were conducted by two reviewers independently. The data were analyzed by Review Manager 5.0.

RESULTSA total of 3 474 patients from 16 RCTs were included in this meta-analysis and patients were divided into exercise rehabilitation group (n = 1 425) and control group (n = 2 049). Meta-analysis results showed mortality rate was similar between the two groups (OR = 0.81, 95%CI 0.38-1.69, P > 0.05) and the incidence of major cardiovascular events rate (OR = 0.40, 95%CI 0.24-0.65, P < 0.01) and heart rate [mean difference (MD) = -2.82, 95%CI -4.72--0.92, P < 0.01] were significantly lower while LVEF (MD = 2.24, 95%CI 0.18-4.31, P < 0.05), the exercise metabolic equivalent (MD = 0.94, 95%CI 0.43-1.44, P < 0.01) , anaerobic threshold (MD = 1.83, 95%CI 0.67-3.00, P < 0.01) , and maximum oxygen consumption (MD = 3.22, 95%CI 2.42-4.03, P < 0.01) were significantly higher in exercise rehabilitation group than in control group.

CONCLUSIONExercise rehabilitation does not increase the risk of mortality in patients of coronary heart disease after revascularization and can effectively reduce major cardiovascular events.

Objective: Alport syndrome was an inherited kidney disease caused by the mutation of COL4A3, COL4A4, or COL4A5. Whole-exome sequencing was used to detect the mutations on these genes for the molecular diagnosis of Alport syndrome. Methods: A 6-year-old girl found accidentally with microscopic hematuria at the age of 4. The clinical data and blood sample of the family including proband, parents, brothers, and sisters were collected. Whole exome sequencing was conducted using their genomic DNAs. Results: A novel heterozygous frameshift mutation c.1826delC (p.Pro609Glnfs*44) was found in the exon 25 of the COL4A4 (NM_000092) in the proband, the father, and the sister, showing an autosomal dominant inheritance pattern of Alport syndrome. This mutation of COL4A4 was confirmed by mutation analysis, and the mutation of c.1826delC was verified by Sanger sequencing. No mutations on COL4A3 and COL4A5 were detected in this family. And the mother and brother are normal wide-type. Conclusions This novel mutation is a valuable addition to the current genetic profile of Alport syndrome, and provide us a better understanding of the disease. Whole-exome sequencing is a power tool to identify the novel mutations of inherited disease and contribute to the molecular diagnosis of disease.
