Surgical drainage of lactational breast abscess with ultrasound-guided Encor vacuum-assisted breast biopsy system.

Lactational breast abscess is a serious complication of mastitis and commonly diagnosed in breast-feeding women. The traditional drainage of breast abscess was often performed with incisive technique which may result in prolonged healing time, regular dressings, dressing pain, interfering with breastfeeding and unsatisfactory cosmetic outcome. As minimal invasive alternatives to incisive drainage, needle aspiration or percutaneous catheter placement cannot completely replace incisive drainage for the inability to treat large, multiloculated or chronic abscess.

Risk factors of bicycle traffic injury among middle school students in chaoshan rural areas of china.

Background: Bicycle injuries are a leading cause of accidental death among children in the world, and bicycle-related injuries are also very common in China, thus to find out bicycle injury risk factors is imperative. This study aims to identify the cyclist-, bicycle- and road-related risk factors of bicycle injury, to develop health education programs as an intervention and to provide a scientific basis for establishing policies against bicycle injury.

Methods: We selected two middle schools randomly among seven schools in Chaoshan rural areas,where the main means of transportation for students from home to school was bicycle.

Oligonucleotide chip, real-time PCR and sequencing for genotyping of hepatitis B virus.

Aim: To compare the oligonucleotide chip, real-time PCR and sequencing for genotyping of hepatitis B virus in Chinese patients with chronic hepatitis B.

Methods: Mixture of samples with different genotypes and clinical serum samples from 126 chronic hepatitis B patients was tested for hepatitis B virus genotypes by oligonucleotide chip, real-time PCR and sequencing of PCR products, respectively. Clinical performances, time required and costs of the three assays were evaluated.

[Clinical significance of AFP-L3 variants determined by micro centrifugal column].

Objective: To evaluate the clinical significance of AFP-L3 in patients with hepatocellular carcinoma.

Methods: Serum AFP-L3 variants were separated by micro centrifugal column, and detected by chemiluminescence.

Results: AFP and AFP-L3 levels were higher in patients with hepatocellular carcinoma than those in patients with chronic hepatitis (P<0.
