Objective To assess the application of intraoperative transesophageal echocardiography for occluding the rupture of aortic sinus aneurysm ( RASA ) by cardiac interventional therapy via mini thoracotomy . Methods After anesthesia transesophageal echocardiography ( TEE ) was performed in patients with RASA to confirm or correct primary diagnosis from transthoracic echocardiography( TTE) and to predict the operative effect . During the operation the guide wire and Sheath pipe were accurately guided into rupture mouth of aortic sinus aneurysm by TEE . After the operation ,the position of closure and the function of aortic valve need to check carefully . Results Collection of 38 patients with aortic sinus aneurysm rupture ,20 patients who can be received interventional therapy were select by TEE . Sixteen patients accepted interventional treatment successfully ,including 8 cases with non‐coronary sinus tumor to break into the right atrium ,5 cases with non‐coronary sinus tumor to break into the right ventricle ,and 3 cases with right coronary sinus tumor to break into the right ventricular outflow tract ( 3 cases) . The patients who received intervention treatment successfully had stable vital signs ,and no obvious changes of heart cavity structure and cardiac function in normal . Postoperative multiple reexamination ,all patients showed the normal closure position ,aortic valve opening and closing movement . And no stenosis and reflux signal ,no residual shunt was detected . Conclusions TEE can confirm or correct primary diagnosis of TTE before the operation and guide the surgery operator to place the closure correctly during the operation and evaluate the effect of the treatment after the operation .

BACKGROUND:Isoflurane is an anesthesia drug that has a certain effect on the nervous system. It possibly causes neurologic disorders through impacting nerve stem cel function or morphology. OBJECTIVE:To investigate the effects of isoflurane on the proliferation and differentiation of neural stem cels in the hippocampus of rats. METHODS:Neural stem cels from the hippocampus of neonatal Sprague-Dawley rats, aged 7 days, were induced and differentiated. Passage 3 cels were obtained and divided into two groups: isoflurane group (a mixture gas of 2.8% isoflurane, 5% CO2 and 95% O2) and control group (a mixture of 5% CO2 and 95% O2).
After intervention of 6 hours folowed by 2 hours of routine culture, anti-BrdU monoclonal antibody immunofluorescent staining was used to detect cel proliferation, and western blot assay to detect the expression of β3-tubulin and glial fibrilary acidic protein. RESULTS AND CONCLUSION:Compared with the control group, the number of BrdU positive cels in the isoflurane group reduced significantly, indicating that isoflurane inhibits the proliferation of neural stem cels. Compared with the control group, the expression of glial fibrilary acidic protein in the isoflurane group up-regulated, but the expression of β3-tubulin had no changes, indicating isoflurane promotes the differentiation of neural stem cels into astrocytes.

ObjectiveTo investigate the effects of swallowing training combined with real-time electrical stimulation on dysphagia after stroke. Methods17 patients, older than 80 years old, with dysphagia after stroke, were treated with Vocastim-Master Physiomed Elektromedizin. They were assessed with the Watian drinking water test, swallowing disorder evaluation, swallowing ability evaluation, and α. ResultsAll the assessment significantly improved in the 17 patients (P<0.001). ConclusionSwallowing training combined with real-time electrical stimulation can significantly improve the swallowing capacity of the patients older than 80 after stroke.

ObjectiveTo determine the responsiveness of 3 assessment for swallowing disorder on elderly people. Methods40 elderly cases with were assessed with drinking test, classification of swallowing disorder, and swallowing ability evaluation before and 3 weeks after treatment. ResultsThe effect size was 1.04 for drinking test, 1.74 for classification of swallowing disorder and 2.06 for swallowing ability evaluation. The standardized response mean was 2.49 for drinking test, 2.35 for classification of swallowing disorder and 2.78 for swallowing ability evaluation. There was very significant difference before and after treatment in the score of all the scales (P<0.001). ConclusionDrinking test, classification of swallowing disorder, and swallowing ability evaluation are responsive for swallowing disorder in elderly people receiving rehabilitation.

OBJECTIVE:To summarize the clinical effect of compound glycyrrhizin(CG)on SARS.METHODS:The clin?ical data of73patients with clinically diagnosed SARS(37cases were treated by CG)were prospectively analysed.RESULTS:After CG treatment,the symptoms of dry cough,chest distress and dyspnea improved quickly and the elevated serum level of aminotransferase decreased.The maximal dosages of corticosteroids used in CG group and control group were(354.3?219.8)mg/d and(430?262.6)mg/d,respectively.The average time to occurrence of antibody,duration for reduction of corticosteroid dosage and duration of hospital stay were shorter in CG group than those in control group.There was no significant difference in titer value of antibody between two groups.CG had little effects on WBC,blood sugar and electrolytes.CONCLUSION:CG may be a promising drug against SARS with less side effect.

Objective:To describe the clinical,radiological and pathological characteristics of idiopa-thic pulmonary haemosiderosis(IPH) in adults and to evaluate the methods of diagnosis and treatment.Methods:Two patients were successfully diagnosed and treated in our hospital and the literature on the subject was reviewed.Results:Two adult patients(19 and 34 years old) diagnosed in our hospital had 5 and 10 years of history of hemoptysis respectively,and chest CT showed bilateral diffuse alveolar opacities over mid and lower zones.Tests of antinuclear antibodies(ANAs),rheumatoid factor(RF),antineutrophilic cytopasmic antibodies(ANCA) and Anti-glomerular basement membrane(anti-GBM) antibody were negative.Haemosiderin-laden macrophages were found in bronchoalveolar lavage fluid(BALF) whose color was yellow.Microscopic examination of the lung tissue specimens obtained by transbronchial lung biopsy(TBLB) revealed hemorrhage and numerous hemosiderin-laden macrophages in the alveoli and no vasculitis or capillaritis were seen.These findings were consistent with a diagnosis of IPH.Steroid therapy had good effects.Conclusion:IPH is a diagnosis of exclusion of other causes of diffuse alveolar hemorrhage(DAH).IPH adults have relatively good drug responses and relatively good prognoses.

Objective To observe the influence of the sperm abnormalities on conventional invitro fertilization therapy outcome. Methods Sperm of 105 infertile husband's semen was analyzed. The patients were divided into three groups according to the sperm morphology observed Using Kruger 's criteria: normal sperm morphology group (sperm normal morphology ≥ 15 % ), mild sperm abnormalities group( sperm normal morphology 10%- 15%), middle sperm abnormalities group (sperm normal morphology 5 % - 10 % ). Fertilization rate, cleavage rate, good quality embryo rate, implantation rate, clinical pregnancy rate and abortion rates were compared to study the influence of the sperm abnormalities on conventional IVF outcome. Results ①Fertilization rate(79.4 % vs 78.3 % ), cleavage rate(104. 6% vs98. 6%), good quality embryo rate(58. 1% vs 53. 9%), implantation rate (31.7% vs 30. 8%), clinical pregnancy rate(48.1% vs 42. 3%)and abortion rates(13.0% vs 18. 2%)were not significantly different between normal sperm morphology group and mild sperm abnormalities group(P>0. 05). ②The fertilization rate (79.4% vs 63.9%), good quality embryo rate(58. 14% vs 48.23%), implantation rate (31.7% vs 16. 7%) and clinical pregnancy rate(48.1%vs24.0%) of the normal sperm morphology group were higher than middle sperm abnormalities group(P<0.05). The abortion rates(13.04% vs 28. 57%) and cleavage rates(104.6% vs 102.9%) were not significantly different(P>0. 05). ③The fertilization rate (78.3% vs 63.9%), good quality embryo rate (53. 9%vs 48. 2%) of the mild sperm morphology group were higher than middle sperm abnormalities group(P <0.05). Implantation rate (30.8% vs 16. 7%) , clinical pregnancy rate(42.3% vs 24.0%) , abortion rates(13. 0% vs 28. 6%) and cleavage rates(104.6% vs 102.9%) were not significantly different (P>0. 05). Conclusions There is a significant influence of middle sperm abnormalities on IVF fertilization rate, good quality embryo rate, implantation rate and clinical pregnancy rate. However, it could not be influenced on mild sperm abnormalities.
