Our goal was to systematically review the current evidence comparing the relative effectiveness of two maxillary sinus floor elevation (MSFE) approaches (internal and external) without bone grafts with that of conventional/grafted MSFE in patients undergoing implantation in the posterior maxilla. ⋯ This systematic review revealed that both non-graft and grafted MSFE had high implant survival rates. Owing to the moderate strength of the evidence and short-term follow-up, the results should be interpreted with caution.

Association of the MMP-3, MMP-9 and MMP-12 gene polymorphisms with COPD risk: a meta-analysis.
Given the evidence that the matrix metalloproteinases (MMPs) play an important role in the pathogenesis of chronic obstructive pulmonary disease (COPD), a number of case-control studies have attempted to assess the relationship between genetic polymorphisms in MMP genes and COPD risk. However, reliable measures of these results are lacking. ⋯ The findings of this meta-analysis suggest that there is a risk of COPD associated with the MMP-9 rs3918242 and MMP-12 rs2276109 polymorphisms in certain ethnic groups.

Erectile dysfunction in testicular cancer survivors: a meta-analysis of case-control studies.
Testicular cancer (TC) is the most frequent cancer among men aged 14-44 years. The risk of erectile dysfunction (ED) in TC patients varied within a wide range across different studies. This study aims to estimate the risk of ED in TC patients by conducting a meta-analysis of case-control studies. ⋯ TC patients experienced an increased risk for ED compared with healthy men. The long-term risk for ED in TC patients was lower than the short-term risk.

The aim of the present study was to explore the correlation between cough variant asthma (CVA) and repeated episodes of mycoplasma pneumonia in children. ⋯ This study demonstrated a correlation between cough variant asthma and mycoplasma pneumonia.

This study examined the protective effects of sophoricoside on neuronal injury and cognitive dysfunction in anaesthetic-exposed neonatal rats. ⋯ Sophoricoside treatment protects against neuronal injury and reduced cognitive function in isoflurane-induced neuronal injury rats by regulating TLR-4 signalling.
