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.

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.

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.

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.

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.

AIM: To investigate the function and the mechanism of transplanting bone marrow derived peripheral blood mesenchymal stem cells(PBMSCs) on restenosis after carotid balloon angioplasty in the model of carotid atherosclerosis rabbits,and to determine if the functions of PBMSCs are enhanced after hypoxia preconditioning.METHODS: Bone marrow cells were mobilized by granulocyte colony-stimulating factor(G-CSF),and PBMSCs were collected through density gradient centrifugation and adherent culture,labeled with enhancement type green fluorescent protein(EGFP) genes.All animals with carotid atherosclerosis stenosis were randomly divided into three groups: hypoxia preconditioning group(n=24,received intravenous transplantation of PBMSCs with hypoxia preconditioning),non-hypoxia preconditioning group(n=24,received normal culture of PBMSCs) and control group(n=24,only received equal-volume of culture medium).Vascular endothelial growth factor(VEGF) was determined by enzyme linked immunosorbent assay(ELISA) at 7 d,14 d and 28 d post-angioplasty,respectively.The vessel morphology,the homing of MSCs and the reendothelialization were analyzed with Weigert staining and immunohistochemistry.RESULTS: Compared to control group,the level of VEGF significantly increased in both hypoxia preconditioning group and non-hypoxia preconditioning group at all time points(P

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.

Objective To investigate the effect of acupuncture decompression operation on the quality of life of patients with mild to moderate essential hypertension. Methods 74 cases of mild to moderate essential hypertension were divided into experimental group and control group by random number table, 4 cases were lost. Finally, a total of 70 patients were included in the data analysis. In the control group, 35 cases were given routine drug taking and health guidance, the experimental group of 35 patients increase the treatment of acupuncture decompression operation points on this basis. The two groups of patients were measured with blood pressure before and after intervention, and World Health Organization Quality of Life (WHOQOL-BREF) was used to evaluate the quality of life, and the data were analyzed. Results The scores of physiological and psychological fields in the experimental group were (15.23 ± 2.66) points and (16.68 ± 2.23) points while the control group were (13.98 ± 2.18) points, (15.25 ± 2.52) points, the difference was statistically significant (t=2.305, 2.522, P<0.05). The experimental group of social relations, environmental score were respectively (1.37 ± 2.24) points, (14.16 ± 1.24) points, while the control group were (13.29 ± 2.30) points, (13.56 ± 1.36) points, 2 groups were not statistically significant (t=0.770, 3.063, P > 0.05). The experimental group systolic blood pressure, diastolic blood pressure were (121.43 ± 6.43) mmHg (1 mmHg=0.133 kPa), (71.74 ± 3.88) mmHg, compared with the control group were (128.34±5.72) mmHg, (76.06±4.43) mmHg. The difference was statistically significant (t=-4.753,-4.210, P<0.05).
