ReviewSelective serotonin reuptake inhibitors in the treatment of premature ejaculation.
To review and assess the update studies regarding selective serotonin reuptake inhibitors (SSRIs) in the treatment of premature ejaculation (PE) and then provide practical recommendations and possible mechanisms concerning state of the art knowledge for the use of SSRIs in alleviating PE. ⋯ The efficacies of the current SSRIs are moderate in the treatment of PE and they have not been approved by the FDA, therefore new SSRI like dapoxetine needs to be further evaluated.

Molecular characteristics of rifampin and isoniazid resistant Mycobacterium tuberculosis strains from Beijing, China.
China is one of the high burden countries of Mycobacterium tuberculosis (TB) infection globally, with high incidence and mortality. We studied the molecular characteristics of rifampin (RIF) and isoniazid (INH) resistant Mycobacterium tuberculosis strains from Beijing, China, in order to find out the genetic marker for rapid detection of specific drug resistance. ⋯ The hot-spot region of rpoB gene can be used as genetic marker for detection of RIF resistant strains; a combined use of both katG315 and inhA-15 can improve the detection rate of INH resistant strains; the Beijing genotype is prevalent in Beijing, China; the modified RIFO assay can be a practical tool for rapid detection of RIF resistant and MDR isolates in the routine diagnostic work.

Differentiation of bone marrow-derived mesenchymal stem cells from diabetic patients into insulin-producing cells in vitro.
Stem cells, which have the ability to differentiate into insulin-producing cells (IPCs), would provide a potentially unlimited source of islet cells for transplantation and alleviate the major limitations of availability and allogeneic rejection. Therefore, the utilization of stem cells is becoming the most promising therapy for diabetes mellitus (DM). Here, we studied the differentiation capacity of the diabetic patient's bone marrow-derived mesenchymal stem cells (MSCs) and tested the feasibility of using MSCs for beta-cell replacement. ⋯ Bone marrow-derived MSCs from DM patients can differentiate into functional IPCs under certain conditions in vitro. Using diabetic patient's own bone marrow-derived MSCs as a source of autologous IPCs for beta-cell replacement would be feasible.

Preliminary clinical outcomes of percutaneous kyphoplasty with Sky-bone expander.
Percutaneous kyphoplasty (PKP) using balloon expander has been proved to be effective in the treatment of painful vertebral compression fractures. Recently, Sky-bone expander, an alternative bone expander for PKP has been developed. The purpose of this study was to show our preliminary clinical outcomes of PKP with Sky-bone expander. ⋯ PKP with Sky-bone expander is an effective and relatively safe alternative to the PKP using balloon expander. It can relieve pain, improve physical function, and restore the height of the collapsed vertebrae, but the cement extravasation is unsolved.
