Application of multiplex competitive PCR combined with capillary electrophoresis in carrier screening of spinal muscular atrophy.

Spinal muscular atrophy (SMA) is an autosomal recessive, fatal neurological disorder in children. The pathogenic gene of SMA is survival motor neuron1 (SMN1). There are many methods to detect SMN1 gene copy number, but few techniques are suitable for large-scale population screening.

A monomer purified from Paris polyphylla (PP-22) triggers S and G2/M phase arrest and apoptosis in human tongue squamous cell carcinoma SCC-15 by activating the p38/cdc25/cdc2 and caspase 8/caspase 3 pathways.

Recent studies have shown that the aqueous, ethanolic extracts and a monomer compound of Paris polyphylla exhibit anticancer activity toward several types of cancer cell lines, but the anticancer activity of (3β,17α,25R)-spirost-5-ene-3,17-diol 3-O-α-L-rhamnopyranosyl-(1 → 2)-β-D-glucopyranoside, a monomer isolated from P. polyphylla (PP), named PP-22, has not been reported previously. In this study, we investigated the effect of PP-22 on human tongue squamous cell carcinoma SCC-15 cells in vitro.

Clinical research on intelligence seven needle therapy treated infants with brain damage syndrome.

Objective: To assess whether the intelligence seven needle therapy administered in infants with perinatal brain damage syndrome (BDS) as early intervention would improve patients' neural development.

Methods: A randomized controlled trial was conducted. Sixty-four infants with BDS were randomly assigned to two groups: the comprehensive group and the control group.
