One hundred and fifteen patients with rheumatic mi- tral stenosis were treated with Percutaneous Balloon Mi- tral Valvuloplasty (PBMV) from August,1988 to May, 1993.110 patient (94.5%) had successful operations. The observations showed that PBMV can enlarge the stenostic mitral orifice area over 1 time (from 1.04?0. 26cm to 2.08?0.32 cm,P

Objective To observe the effects of early enriched environment intervention on the expression of growth-associated protein-43(GAP-43) in the hippocampus of rats with hypoxic-ischemic brain injury (HIBI). Methods After the establishment of HIBI model in SD rats by the method of Rice, the animals were divided randomly into 2 groups: the intervention group and non-intervention group. The sham-operation rats were used as control group. Enriched environment intervention had been administrated to the rats of intervention group since the 2nd day after HIBI. On the 3rd, 7th, 14th, 21st and 28th day, immunohistochemistry and RT-PCR were used to measure the expressions of GAP-43 protein and mRNA in the hippocampus of rats. Results The expression of GAP-43 protein and mRNA in the rat hippocampus were increased in the non-intervention group than in the control group(P

Objective To observe the effects of environmental stimulation at different stages of development on postnatal rats with hypoxia-ischemic brain injury (HIBI). Methods HIBI postnatal SD rats models were established by dissecting and ligating the left common carotid artery, and after 2 h of recovery, exposing to 8% oxygen-92% nitrogen gas mixture for 2 h. The HIBI rats were randomly divided into early intervention groups, late intervention group, non-intervention group. Intervention group were kept in enriched environment before or after weaning for 20 d. Non-intervention group and control group were kept in a standard environment. Space learning and memory were tested with Morris water maze. Results The ability of space learning and memory in early intervention group was better than that in late intervention group (P

Objective To observe the expression of growth-associated protein-43(GAP-43) in the hippocampus of neonatal rats with hypoxic-ischemic brain damage (HIBD). Methods HIBD was established by the method of Rice in 48 SD rats aged 7 days and another 48 matched normal rats served as control. Immunohistochemistry and RT-PCR were respectively used to detect the expression of GAP-43 protein and mRNA in all rat hippocampus on day 8, 10, 14, 21, 28, 35 after HIBD (n=8 at each time point for each group). Results The expression of GAP-43 protein and mRNA in hippocampus was obviously increased in HIBD rats as compared with normal rats, the peak of GAP-43 protein appeared at 3rd week, and the peak of mRNA at 2nd week. Conclusion The expression of GAP-43 protein and mRNA increased in the hippocampus of rats following HIBD, which was possibly related to the recovery of injured hippocampus.

Objective The objective of this study was to evaluate the clinical significance of coronary stenting in patient aged more than 70 years old.Methods The results of coronary stenting (14 with acute myocardiac infarction) were analyzed and compared them to 36 patients aged from 50 to 60 years old. Results The clinical success rate of coronary stenting for elderly group was 96.8%. The reanginal rate during 3 to 44 (21 ? 14) months' follow up of was 23% . No significant difference in the success and reanginal rate was observed between the two groups and no death case was found in the 14 elderly patients with acute myocardiac infarction.Conclusion Our data suggest that coronary stenting is a very safe and effective method of coronary revascularization in elderly patients.

Objective To observe the effect of early enriched environmental intervention on synaptic ultrastructure and the synaptophysin expression (p38) in hippocampal CA1 area after hypoxia-ischemic brain damage(HIBD) in neonatal rats. Methods The rat model of HIBD was made by the method of Rice in 20 Sprague-Dawley rats, and divided randomly into 2 groups: the intervention group, non-intervention group. Another 10 rats underwent sham-operation as control. From the second day after HIBD, the rats of the intervention group were kept in an enriched environment for 20 d, the rats of non-intervention group and sham-operation group were raised in standard enviroment instead. The hippocampal ultrastructure was observed with electron microscope and the p38 expression was detected immunohistochemically in all rats. Results The ultrastructure of hippocampus CA1 pyramidal neuron in the non-intervention group were distorted as compared with that in the intervention group and control group. The corrected optical densities (COD) of immunoreactive products of the hippocampal p38 were significantly decreased in non-intervention group as compared with intervention group and control group (P0.05). Conclusion Early enriched environment intervention could improve the synaptic reconstruction and reduce the ultrastructural damage induced by hypoxic-ischemia.

Objective To observe the effects of different environment stimulation on the nestin expression in hippocampus and the ability of learning and memory of rats after hypoxic-ischemic brain damage (HIBD). Methods Rat HIBD models were established by the method of Rice in 45 SD rats, then randomly divided into three groups: standard environment stimulation group (SE), enriched environment stimulation group (EE), and impoverished environment stimulation group (IE). Another 15 rats only underwent sham-operation. Different environment intervention that was designed according to Puurunen and Bourgeon’s literatures was applied to the rats on day 2 after HIBD operation. On day 28, Morris water maze was used to evaluate the ability of learning and memory. Then the nestin expression in the hippocampus was measured by immunohistochemistry. Results The ability of learning and memory of IE group reduced and was much lower than that of sham-operation group, SE group and EE group, that of SE group was lower than that of sham-operation group and EE group, but no significant difference between sham-operation group and EE group. Immunohistochemical analysis showed that nestin expression in the hippocampus of EE group significantly increased as compared with that of other groups and that of SE group was stronger than that of sham-operation group and IE group. Conclusion The EE stimulation could increase the nestin expression in the hippocampus of neonatal rats with HIBD, enhance neuranagenesis, and improve the ability of learning and memory, while the IE stimulation could decrease the nestin expression, inhibit neuranagenesis, and impair the ability of learning and memory.

Objective To evaluate the subjective and objective improvement of quality of life in patients with low-temperature plasma-assisted modified uvulopalatopharyngoplasty (H-UPPP) combined with lymphoidectomy in radix lin-guae and coblation-channeling of the tongue(CCT) treating for severe obstructive sleep apnea hypopnea syndrome (OSAHS) , and compare the surgical efficacy with that of H-UPPP. Methods A total of 81patients with severe OSAHS were divided in-to treatment group (n=42) and control group (n=39). Treatment group underwent the low-temperature plasma-assisted H-UPPP combining lymphoidectomy in radix linguae and CCT,and control group underwent H-UPPP treatment. The apnea hy-popnea index (AHI), the lowest saturation of arterial oxygen (LSaO2) and Quebec sleep questionnaire (QSQ) and Epworth sleepiness scale (ESS) before operation and 6-month after operation were recorded and compared between two groups. Re-sults All of detection indicators were significantly improved after operation in treatment group (P＜0.01). The total surgical efficacy was significantly higher in treatment group than that of control group (83.3%vs 12.8%,χ2=40.225,P＜0.01). The to-tal improvement rate of five dimensions in QSQ such as daytime sleepiness symptoms (76.2%vs 25.6%), signs during the day (71.4%vs 10.2%) and night (54.8%vs 5.1%), emotion (54.8%vs 2.5%), ability of social intercourse (50.0%vs 2.5%) and the total score (57.1%vs 7.7%) after operation were significantly higher in treatment group than those of control group. The se-vere indexes of ESS decreased to 23.8% after operation in treatment group than those of control group (51.3%). Conclu-sion Low-temperature plasma-assisted H-UPPP combined with lymphoidectomy in radix linguae and CCT is effective in patients with severe OSAHS, which can also improve the quality of life postoperatively.
