BACKGROUND:More recently, studies have demonstrated that bone marrow mesenchymal stem cel s can be induced in vitro to differentiate into neuron-like cel s that are used for in vivo transplantation to repair nerve damage.
OBJECTIVE:To study the effect of bone marrow mesenchymal stem cel transplantation on learning and memory ability of senile dementia rats.
METHODS:Thirty male Sprague-Dawley rats were randomly divided into three groups:normal control group, stem cel therapy group and model control group. Rats in the latter two groups were used to establish animal models of senile dementia by intracranial injection ofβ-amyloid 1-40. Three weeks after modeling, rats were given bilateral hippocampal injection of induced bone marrow mesenchymal stem cel suspension in the stem cel therapy group, whereas no treatment was given in the normal control and model control groups. Morris water maze test was used to detect learning and memory ability of rats, and rat’s brain tissues were detected pathological y using hematoxylin-eosin staining.
RESULTS AND CONCLUSION:After modeling, the escape latency was higher and the cross-platform frequency was lower in the model control group compared with the normal control group. After cel transplantation, the escape latency and cross-platform frequency were gradual y shortened and increased with time, respectively. Compared with the model control group, the learning and memory abilities of rats were improved in the stem cel therapy group. The brain tissues were relatively intact in structure and exhibited less cel degeneration and necrosis in the stem cel therapy group compared with the model control group. To conclude, bone marrow mesenchymal stem cel transplantation exerts certain therapeutic effects on senile dementia by effectively improving the learning and memory ability.

Contracture and spasticity of ankle joints were major sources of disability in neurological impairment including stroke and cerebral palsy, etc. The manual stretching used in physical therapy might be laborious and time-consuming to the therapists and the outcome was dependent on the experience and the subjectiveend feelingof the therapists. A device was developed that could safely stretch the an-kle joint to its extreme positions with quantitative control of the resistance torque and stretching velocity. Furthermore, it could satisfy a strong need for quantitative and objective measures of the impairment and rehabilitation outcome. This was just the meaning intelligent stretching referred to. This article described the origin of the concept of intelligent stretching and its definition, operational principle, and su-periority and weakness, as well as its application in ankle joint spasticity and contracture in patients with stroke and cerebral palsy.

OBJECTIVETo evaluate the clinical value of multicolor melting curve analysis(MMCA) for detecting genetic mutations in G6PD deficiency.

METHODSA total of 402 peripheral blood samples(256 males and 146 females) were collected from suspected patients or their relatives at the Prenatal Diagnosis Center of Liuzhou Maternal and Child Health Hospital between March 2012 and May 2012. The samples were screened by G6PD/6PGD quantitative ratio testing. The reliability of the assay was evaluated by multiplex probe melting curve assay(which can detect 16 G6PD mutations) and DNA sequencing through a double blind study.

RESULTSOne hundred seventy cases with G6PD/6PGD ratio < 1.0 and 232 cases with G6PD/6PGD ratio ≥ 1.0 were detected by the enzymological method. DNA sequencing has identified 182 wild type samples, 151 hemizygous mutation samples, 5 female homozygous mutation samples, 54 female heterozygous mutation samples and 10 female double heterozygous mutation samples. Multicolor melting curve analysis has detected 185 wild type samples, 148 hemizygous mutation samples, 5 female homozygous mutation samples, 55 female heterozygous mutation samples and 9 female double heterozygous mutation samples. The specificity and sensitivity of G6PD gene mutation detection by multicolor melting curve analysis were 100%(182/182) and 98.6%(217/220), respectively. The positive predictive value and negative predictive value were 99.5%(216/217) and 98.4%(182/185), respectively, and the Youden's index was 0.986. The concordance rate of the sample detection between the melting curve assay and DNA sequencing was 99.0%(398/402). Twenty-one different genotypes were detected by the multicolor melting curve analysis and 24 different genotypes were detected by DNA sequencing. Four samples containing mutations(c.196T>A or c.406C>T) were not detected by multicolor melting curve analysis, which can be attributed to different technical settings of the two methods.

CONCLUSIONMulticolor melting curve analysis for G6PD gene mutation detection is a simple, rapid, sensitive and specific method, which can be used for clinical diagnosis of G6PD deficiency.
