Objective To observe and compare the clinical efficacy,recurrence rate and safety of differ-ent courses of inhalation fluticasone propionate in treatment of children with cough variant asthma. Methods A total of 101 children with cough variant asthma in our hospital were randomly divided into three treatment groups,all with the same therapy drug -fluticasone propionate and with the treatment time of two months, six months and nine months respectively. Clinical efficacy and treatment compliance were followed up during the treatment. After discontinuation,observation for the relapse of cough was followed up for 6 months. In inhalation therapy before and after,bone mineral density( BMD) and blood cortisol,electrocardiogram were monitored re-spectively to observe its safety. Results Three groups of children with cough were all get effective control,with no significant difference(H=5. 2894,P=0. 0710). The two months treatment group(A group)was more easy to relapse than the six months treatment group( B group) and the nine months treatment group( C group) after drug withdrawal,statistically significant(χ2 =4. 858 1,P=0. 027 5;χ2 =4. 482 6,P=0. 034 2). But after drug with-drawal,there was no significant difference in the rate of relapse in B and C group(χ2 =0. 022 2,P=0. 881 4). There were few changes in laboratory values about morning serum cortosol concentrations. There was no signifi-cant decrease in BMD after treatment. No other adverse events were observed in this study. Conclusion Flutica-sone propionate inhalation treating children cough variant asthma has good effection. A long period of treatment scheme(6 months)has better curative effect and lower recurrence rate after drug withdrawal.

Objective　To analyze the advantages of intracrani al hematoma smash puncture (IHSP) in the treatment of cranial hemorrhage for the elderly. Methods　A total of 104 cases of cerebral hemorrhage a dmitted in the recent 3 years were collected and divided into 4 grou ps, i.e . group A, elderly with IHSP treatment (n=36), group B, elderly with regular medical treatment (n=33), group C, non-elderly with IHSP treatment (n= 21) and group D, non-elderly with routine therapy (n=14). The clinical and follow-up outcomes were studied and analyzed. Results　There w as significant difference in rehemorrhage rate after puncture between grou p A (0/36) and group C (2/21). Significant difference was found in early mortali ty rate in group A (16.67%) and group B (39.40%). The rate of activity of daily living (ADL) 1-2 was significantly higher in group A (58.62%) than group B (5.88 %)(P<0.005) and that of ADL 4-5 was obvious lower in group A (13.79%) than g roup B (47.06%)(P<0.025). Conclusion　Intracranial hematoma smash hemorrage is safe and efficient in the treatment of elderly cerebr al hemorrhage, especially in reducing the disability rate.

Objective To investigate the interference effect of calcium dobesilate on serum creatinine levels by Sarcosine oxidase-based assay.Methods 1.Interference test in vivo:Ten patients with chronic renal diseases from Huangshi second hosptial were recruited.Serum creatinine (sarcosine oxidase method,Scr1 ; deiminase method,Scr2),urea,and cystatin C were detected and compared before and after one week administration of calcium dobesilate; 2.Interference test in vitro:to detect whether 100 mg/L calcium dobesilate has any interference with Scr1 and Scr2; 3.Dose-dependent interference test:To detect the interference effect of different concentrations of calcium dobesilate (1.25-20.0 mg/L) on different creatinine concentrations (404.5 μmol/L or 65.9 μmoL/L) measured by sarcosine oxidase assay.Bias within 3.5％ or 6.63 μmol/L of creatinine levels was clinically acceptable.Statistical comparisons were made using Wilcoxon rank-sum test.Results There was significant difference of sarcosine oxidase-based serum creatinine levels between before and after one week administration of calcium dobesilate (P ＜ 0.05),while no significant differences were observed for deiminase-based serum creatinine levels,urea and estimated GFR values (P ＞ 0.05).Interference test showed that 95％ confidence interval of interventional value (Dobs) of calcium dobesilate (100 mg/L) was (-173.9 ± 2.86) μmol/L for the sarcosine oxidase assay and (1.21 ± 3.14) μmol/L for deiminase method,indicating that calcium dobesilate caused a significant negative effect on the former enzymatic assay but not the latter one.In the dose effect interference test of calcium dobesilate,the regression equations were:Y =-2.7649X-0.0782 (R2 =0.998,F =7943.4,P =0.000) for high creatinine levels and Y =0.0263X2-1.6394X-0.2754 (R2 =0.996,F =2546.7,P =0.000) for low creatinine levels.The interference effect was less than the predetermined d with the calcium dobesilate concentrations of 4.4 mg/L in high concentration specimen and 3.5 mg/L in low concentration specimen.Conclusions Calcium dobesilate has a significant negative interference with serum creatinine detected by the sarcosine oxidase method,which leads to the bias of creatinine in patients with renal insufficiency.Hence,sarcosine-oxidase-based creatinine levels should be cautious when calcium dobesilate was used,and further check with another assay is necessary if possible.

Objective To evaluate the outcomes of thoracoscopy-assisted mini-incision procedure in patients with lung cancer.Methods From January 2003 to June 2003,66 patients with non-small cell lung cancer were treated in our hospital by lobectomy combined with mediastinal lymph node resection using thoracoscopy-assisted mini-incision(36 patients,VATS Group)or traditional surgery(30 patients,traditional group).The clinical and follow-up data of the two groups were compared after the operation.Results No significant difference was found in the operation time between the VATS and traditional groups(114.6?47.4)min vs(123.3?43.9)min,t=-0.768,P=0.449],while the postoperative hospital stay of the VATS group was significantly shorter than that in the traditional group (9.2?1.4)d vs(10.5?1.7)d,t=-3.408,P=0.001].Log-rank test showed that the survival curve in the two groups was comparable(?2=0.270,P=0.605).Cox regression model indicated that the pathological characteristics(risk ratio:3.912,P=0.000),TNM stage(risk ratio:3.737,P=0.000),and lymph node metastasis(risk ratio:15.495,P=0.000)were independent,unfavorable prognostic factors for the disease;whereas,no relation was detected between the thoracotomy incision and prognosis(P=0.414).Conclusions Thoracoscopy-assisted mini-incision procedure is a safe and reliable approach for patients with lung cancer with satisfying outcomes.

Objective To explore the efficacy of endoscopic surgery for juvenile nasopharyngeal angiofibroma.MethodsDuring 27 years from March 1980 to July 2007,we performed endoscopic surgery on totally 19 patients with nasopharyngeal angiofibromas.According to Radkowski Stating,five of the patients were stage ⅠA,ten were stage ⅠB,and 4 were stage ⅡA.Before the endoscopy,superselective embolization was performed in all the cases via bilateral maxillary arteries.Results All tumors were successfully resected by endoscopy.The intraoperative blood loss was 200-600 ml.One of the stageⅡA patient developed cerebrospinal rhinorrhea during the endoscopic resection,and thus received repair of the middle turbinate by a mucosal patch immediately.In this series of patients,no massive epistaxis,intracerebral infection,or blindness occurred.Follow-up at three months after the surgery by nasoscopy showed epithelialisation of the nasal mucous membrane without residual tumor tissues.Meanwhile,otoscopy revealed normal light reflex of the eardrum,no fluid in the middle ear.Of the patients,eleven were followed up for one to five years,during which none of them had recurrent tumors confirmed by nasoscopy or CT scan.Conclusions Endoscopic resection of nasopharyngeal angiofibroma results in little trauma and few blood loss after superselective embolization.Experience and surgical skills are key points for the operation.
