In this paper, we analyze the status of the medical device testing and the situation of the unqualifie varieties by sorting out the situation of the national medical device supervision and inspection from 2013 to 2016. We analyze the results of the inspection deeply, and find that the safety risk points exists in the quality of the medical device testing products and management system, product technology requirements, the national standards, industry standards or other aspects, then explain one by one with typical examples. At the same time the corresponding suggestions are put forward to production companies and regulators respectively on the existing problems.

Prostate cancer antigen 3 (PCA3) has emerged as a critical biomarker for the early detection of prostate cancer, complementing the traditional prostate-specific antigen (PSA) testing. This research presents a novel resistive sensor based on reduced graphene oxide (RGO) functionalized with glutaraldehyde (GA)/complementary single-stranded DNA (ss-DNA) for the detection of the PCA3 RNA. The device was meticulously characterized at each fabrication step to confirm the successful integration of the various layers on the sensor device, utilizing atomic force microscopy (AFM) which confirmed the increase in the thickness of the sensor from ∼1.

Background: Daptomycin pharmacokinetics and pharmacodynamics data relative to higher doses in patients are necessary for clinical practice.
Objectives: A monocentric, prospective study that enrolled patients with a diagnosis of spp. infective endocarditis treated with daptomycin according to clinical practice, to evaluate the pharmacokinetics/pharmacodynamics of different daptomycin daily doses (group A: 8-10 and group B: 11-12 mg/kg).

Introduction: To date, no investigations have been published regarding the concentration, dose, and technique for a mucosal spray application of botulinum toxin A (BTA) to alleviate hypersecretory symptoms of rhinitis in humans. It is a promising option for reducing common symptoms of seasonal allergic rhinitis (AR) and idiopathic non-AR. It is safer and less painful than intranasal injections, with high reported satisfaction in reducing clinical symptoms.

Objective: The purpose of this study was to evaluate the association of pain-related anxiety on abdominal muscles thickness during standing postural tasks among individuals with chronic low back pain (CLBP).
Methods: We obtained responses to a pain-related anxiety symptoms questionnaire from 50 participants with CLBP. We then separated participants into high (11 men, 14 women) and low pain-related anxiety (13 men, 12 women) groups and compared assessments of their lateral abdominal muscles thickness during standing tasks on a computerized balance assessment device, using one static level and 2 movable levels (levels 6 and 3 are represented easy and difficult tasks respectively).
