Objective:to study memory impairment of patients with stroke in internal capsule-basal ganglia.Method:40 inpatients with stroke in internal capsule-basal ganglia and 25 aged matched normal control received assessment with MMSE (mini mental state examination), WMS-RC (Wechsler memory scale-Chinese revised), AVMT (auditory verbal memory test) and MPS (memory for pictorial scenes test). The patients were assessed in 20 days after stroke while the loci were determined by cranial CT or MRI.Result:among patients, the total scores of these memory tests were associated with cerebral atrophy, educational level, and leukoaraiosis. The volume of lesion and leukoaraiosis played a major role in memory coding strategy in MPS test. There were still significant differences in above memory tests between patients without cerebral atrophy and the matched controls.Conclusion:damage of sub-cortical rgions, such as lesions of internal capsule-basal ganglia, may cause memory impairment.

OBJECTIVE: Analysis of multislice CT (MSCT) on the misdiagnosis reasons of children bronchial foreign body, avoid missed diagnosis, to achieve reasonable application. METHOD: Fourteen cases of misdiagnosed cases of data were retrospectively analyzed in our department of suspicious in children with bronchial foreign body, and discuss the misdiagnosis reasons. RESULT: Fourteen cases of misdiagnosis of children with 9 cases by MSCT examination showed no obvious foreign matter. Through bronchoscopy intraoperative found foreign body, 5 cases by multislice CT (MSCT) to found foreign body, 4 cases of phlegm scabs, 1 case is inflammatory granulation, all recovered after treatment. Reasons of misdiagnosis were threshold selection error, scanning level from the inception glottis, imaging error, etc. CONCLUSION MSCT is a very valuable diagnostic on airway foreign body check method, but there are certain limitations, we should improve the understanding of misdiagnosis and reduce the occurrence of this phenomenon.

BACKGROUND: Defected Laryngeal cartilage has many alternatives, including autologous cartilage, al ograft cartilage and metal stents. Although these materials can achieve desired outcomes in laryngeal cartilage defect repair, certain limitations exist. OBJECTIVE: To investigate the biocompatibility and properties of artificial ossicular chain reconstruction materials, and to explore the effect of artificial ossicular chain reconstruction materials on laryngeal cartilage defect repair. METHODS: Porous hydroxyapatite otosteon was prepared by high-temperature calcination of hydroxyapatite, fol owed by cultured in bone morphogenetic protein solution extracted from fresh human bone to construct bone morphogenetic protein-hydroxyapatite artificial ossicular chain reconstruction material. And then, the biocompatibility and characteristics of the material were analyzed. Forty adult male New Zealand white rabbits were randomly divided into porous hydroxyapatite group and artificial ossicular chain reconstruction material group (n=20 per group), and underwent repair with porous hydroxyapatite material and bone morphogenetic protein-hydroxyapatite artificial ossicular chain reconstruction material respectively after modeling of laryngeal cartilage defect. RESULTS AND CONCLUSION: There was a significant difference in compressive strength of artificial ossicular chain reconstruction materials with different porosities. No symmetry sphere formed in hol ows of the outer surface of the material, with polygonal appearance and with a pore size of 100-200 μm. There were no obvious adverse reactions in both two groups after implantation, but in the artificial ossicular chain reconstruction material group, numerous fibrous connective tissues and obvious bone nodules appeared, and the degradation rate of the material was faster. These results suggest that the bone morphogenetic protein-hydroxyapatite artificial ossicular chain reconstruction material exhibits good biocompatibility and properties, which wil obtain satisfactory outcomes for laryngeal cartilage defect repair. So, the material holds a great value of clinical application.

Prevalence of dislipidemia is increasing rapidly in China and there has been a growing interest in Chinese herbal medicine for the treatment of hyperlipidemia both inside and outside China. In this article, lipids regulating effects of 9 herbs or their extracts and 5 herbal formulae which have been published in English-language literature are reviewed. Although evidence from animals and humans consistently supports the therapeutic activities of these Chinese herbal medicines, few multi-center large-scale clinical trials have been conducted to confirm the efficacy and evaluate their safety.

SARS coronavims is an emerging virus. A lot of animals could be infected by SARS-CoV and Himalayan palm civets, as one of important hosts, is an ideal animal model. Viral genetic factors have been implicated in the emergence of SARS-CoV, with the suggestion that this virus is a recombinant between mammalian and avian coronaviruses. However, the recombination is unlikely to explain the appearance of SARS in humans.

AIM: To investigate the quality of life in adults with strabismus and evaluate the improvement in quality of life after treatment.
METHODS: In this prospective study, forty-five adults with a diagnosis of strabismus conform to the inclusion and exclusion standard were selected in our hospital from October 2013 to May 2014, as experimental group and 45 normal adults were enrolled as control group. A Chinese Adult Strabismus-20 questionnaire was used to evaluate the differences of quality of life between patients with strabismus and normal adults, and to evaluate the differences of quality of life in patients with strabismus preoperative and 6mo postoperative.
RESULTS:The scores of quality of life in adult patients with strabismus preoperative and 6mo postoperative were statistically significant lower than those of normal adults (P< 0. 01). In 6mo postoperative, the scores of quality of life statistically significant increased than preoperative ( P<0. 01).
CONCLUSION: Strabismus can decrease the quality of life in psychosocial and visual functional for adults and the surgical treatment can improve quality of life in patients with strabismus.

Objective To discuss the value of medium resolution typing method for HLA-B antigens of Northern Chinese by DNA chip technique.Methods The chip was made with specific medium distinguish typing probes designed according to gene frequency of HLA-B alleles from Northern Chinese.Unsymmetrical PCR was used to amplify HLA-B exon 2 and 3, then labeled PCR products and hybridize with probes on the chip.Certified the typing of HLA-B by analysed and scanned the signals of hybridize through a set of computer software.Results HLA-B alleles were successfully typed in 30 clinical samples. This medium distinguish probes were able to discern 42 HLA-B alleles from the scope of HLA-B 7~83. Using it we can distinguish B14,73 and 82 three new alleles contrast to PCR-SSP methods.Conclusions DNA typing of HLA-B by chip was proven to be a high-resolution and high-specificity method. It is able to check out the multitudinous samples in one DNA chip and it is more suitable for clinical application.

Objective To value the clinical application of diffusion tensor imaging (DTI) in cerebral diseases. Methods Six volunteers and 6 patients (including 3 patients with ischemic stroke and 3 patients with glioma) were examined by DTI and T1weighted, T2weighted MR scan. All data were processed with DtiStudio software to show the white matter fiber tracts. The fractional anisotropy (FA) of the diffusion tensor were measured between the affected and the unaffected side. Results The white matter fiber tract could be observed clearly on the FA map. The pyramidal tract with different degree disruption could be showed in 3 patients with ischemic stroke. Compression, displacement, infiltration or destruction of pyramidal tract, corpus callosum or internal capsule and external capsule could be seen in 3 patients with glioma, and FA was significantly reduced on the affected side as compared to the unaffected side. Conclusion Diffusion tensor imaging is useful in observing the damage and displacement of the white matter fiber tracts in vivo, beneficial to the surgical plan for patients and prognosing recovery of function.

The perinatal risk factors of transient hypothyroxinemia(TH) in premature very-low-birth-weight infants (VLBWI) was investigated by longitudinally assessing thyroid hormones concentrations during their early life after birth and analyzing the relationship to perinatal factors. The serum TT4 concentration on day 7 was (61.03±24.19)nmol/L and the incidence of TH was 12. 05% (n= 10). Pulmonary surfactant support ( OR = 14.25, 95% CI2. 61-70. 07), ventilation support ( OR = 13. 76,95% CI 2. 55-68. 05) , dopamine support ( OR = 9.45, 95% CI 2. 26-39. 5 ) , and gestational age less than 30 weeks ( OR = 5. 78,95% CI 1. 36-24. 49) were perinatal risk factors for TH of premature VLBWI.
