Analysis of patency rates and factors associated with arteriovenous fistula in maintenance hemodialysis patients followed for 10 years.

Objective: This study analyzed the long-term arteriovenous fistula (AVF) patency rate and its determinants in patients undergoing maintenance hemodialysis.

Methods: General data and laboratory examinations of hemodialysis patients were collected retrospectively. The primary patency time, primary functional patency time, cumulative patency time, cumulative functional patency time, and temporary central venous catheterization (CVC) time were counted.

Efficacy of ginseng and its ingredients as adjuvants to chemotherapy in non-small cell lung cancer.

Chemotherapy is applied to treat non-small cell lung cancer (NSCLC), but often limited due to its unstable therapeutic effects and adverse reactions (ADRs). Ginseng and its main ingredients (ginsenosides and polysaccharides) have been clinically used as adjuvants to chemotherapy. However, their efficacies were based on individual trials with relatively small sample sizes, and it is difficult to draw a valid conclusion.

Management of Residual and Recurrent Aneurysms After Clipping or Coiling: Clinical Characteristics, Treatments, and Follow-Up Outcomes.

Background: Recurrent intracranial aneurysms (RAs) remain a daunting challenge for neurosurgeons. This study aimed to explore a potential optimal management strategy of RAs by reviewing the characteristics and management outcomes of 117 RAs.

Methods: A total of 117 patients with RAs were treated in a single neurosurgical center from January 2011 to January 2017.

Comparison of gene expression profiles in BALB/c 3T3 transformed foci exposed to tumor promoting agents.

Identification of specific etiological carcinogens is one of the most important issues in environmental-toxicology studies. In this study, cDNA microarrays were used to analyze gene expression and discern chemical-associated profiles induced by a variety of tumor promoting agents in transformed cells. Two-stage transformation model of BALB/c 3T3 cells was established with MNNG as initiator, and 12-O-tetradecanoylphorbol-13-acetate (TPA), okadaic acid (OA), or cadmium chloride (CdCl(2)) as tumor promoters.

[Medical devices adverse events and its preventive measures].

The text analyzes the reasons of medical devices adverse events occurrence from manufacturers, medical institutions and patients. To guard against the events, the medical institutions should put emphasis on check of purchasing, informed consent, technical permission, SOP performing, the safe of medical and enhance monitoring etc.
