Objective To evaluate file efficacy and safty of central venous cathetr compared with conventional chest tube for closed pleural drainage in the treatment of traumatic hemothorax Method Totally 299 patients of traumatic hemothorax with middling or large effusions,in emergency department,Second Hospital .Affiliated to Medical College of Zhejiang University,from January 2003 to May 2007,were prospective controlled studied.All the 299 patients of were divided into catheter group (n=156) or tube group(n=143) according as patients'hospitalization date was odd or even number respectively.Patients in catheter group underwent drainage by central venous catheter using the Seldinger technique,and patients in tube group did by conventional chest tube using conventional technique.A unue drainage bag system or a wate seal system was connected with the end of the catheter or the tube respectively.The surgical operation time,the successful rate of treatment,the occurreuce rate of serious complications,the using rate of anodyne,the time of cut concrescence and the occurrence rate of cut infection were compared,and the drainage time and the correlative expenses in patients treated successfully were further compared.The data were analyzed by using t or X2 test with SPSS 13.0.A P value less than 0.05 indicated statistical signficance.Results Compared with robe group,the surgical operation time,the using rate of anodyne,the time of cut concrescence and the occurrence rate of cut infection were significantly decreased(P<0.05) in catheter group.There were not significant differences between two groups in the suecessful rate of treatment and the occurrence rate of serious complications(P>0.05).There were not significant differences between two groups in the drainage time and the corrective expenses of patients treated successfully(>0.05).Conclusions Use of central venous catheter catheters for closed pleural drainage in the treatment of traumatic hemothorax is effective,safe,and well-tolerated.It was more simple and less invasive as a procedure compared with conventional large-bore chest robe.

Objective To compare the serum levels of transforming growth factor (TGF)-beta 1,bone morphogenetic protein (BMP)-4 in patients with rheumatoid arthritis (RA) and RA with interstitial lung disease (RA-ILD).Methods Twenty-eight RA-ILD patients,32 patients with RA but without ILD and 20 normal controls were enrolled.The RA-ILD group was further divided into early group and late group.All the observed subjects were analyzed using enzyme linked immunosorbent assay (ELISA) for the determination of serum TGF-β1 and BMP-4 levels.The relationship between the serum levels of TGF-β1,BMP-4 and laboratory examinations were investigated.Comparisions between groups were tested by one-way ANOVA analysis and ttest.Correlation of indexs were observed by Spearman method.Results Patients in the RA-ILD group were older than RA group in disease onset age,in addition,patients with ILD had better joint function and higher serum rheumatoid factor titers.The occurrence time of interstitial lung disease was 2-6 years after the onset of arthritis,with an average time of (3.0±1.2) years.The TGF-β1 levels in the RA-ILD group were slightly higher,but not statistically significant than other groups (P＞0.05).The TGF-β1 serum levels in the early RA-ILD patients were significantly increased than those of the late RA-ILD group and the RA group.BMP-4 levels in patients with RA-ILD group were less than RA without ILD group and healthy control group,and the difference was statistically significant (P＜0.05).BMP-4 level in early RA-ILD group was significantly decreased than those of the late RA-ILD group and RA group.No correlation between the serum BMP-4,TGF-β1 level (P＞0.05) no assay result correlated with laboratory parameters including ESR,CRP,RF and anti-CCP antibodies (P＞0.05).Conclusion TGF-β1 serum levels are increased and BMP-4 levels are decreased in early RA-ILD patients.The serum levels of TGF-β1 and BMP-4 may be indicatior for asymptomatic ILD and reflect disease progression.

Objective To investigate the efficacy and toxicity of stereotactic ablative radiotherapy for stage Ⅰ peripheral non-small cell lung cancers.Methods Thirty six patients of stage Ⅰ peripheral non-small cell lung cancers were treated with stereotactic ablative radiotherapy.The prescription dose was 12 Gy per fraction ×4 fraction in one to two weeks.The 100％ planning target volume (PTV) was covered by the isodose curve of 95％ prescription dose.Organs at risk and their respective tolerance doses used during treatment planning were developed from the research scheme of the Radiation Therapy Oncology Group 0236.Before the radiation delivery,all patients were scanned by the fan beam CT or the cone beam CT for image guidance and registration.The follow-up for the patients was given to observe the toxicity and efficacy of stereotactic ablative radiotherapy (SABR).Results The median follow-up time was 18.7 months (range of 4 to 36 months).After treatment,the overall response rate was 88.9％,with complete response (CR) 17 cases(47.2％),partial response (PR) 15 cases(41.7％),and stable disease (SD) 4 cases(11.1％).The estimated overall survival rate at 1 and 3 years was 92.3％ (95％ confidence interval [CI],86.3％ ～97.1％) and 85.3％ (95％ CI,80.5％ ～90.6％).The estimated local control rate at 3 years was 90.2％ (95％ CI,85.7％ ～94.8％).There was no gradeⅢ or above toxicity related to treatment.Conclusions The stereotactic ablative radiotherapy attains good local control and survival efficacy for the stage Ⅰ peripheral non-small lung cancer patients.It is well tolerated owing to low toxicity.

Objective To investigate the prevalence of hypertension and the current status of awareness, treatment and control of hypertension in Chinese cardiovascular physicians. Methods A total of 4032 cardiovascular certified physicians were recruited from 386 medical centers in all 31 provinces and municipalities in mainland China between 1 June 2008 and 31 August 2008. Results The prevalence of hypertension in Chinese cardiovascular physicians was 12.1%, and there were gender differences and age group differences among them. Among hypertensive patients, the percentage of awareness, treatment and well-controlled of hypertension were 80.0%, 75.7% and 42.4%, respectively. There were age group differences between awareness rate and treatment rate. Conclusion There exist a considerable prevalence of hypertension in Chinese cardiovascular physicians surveyed, and the prevention and control should be further strengthened.

ObjectiveTo investigate the association of hypertensive target organ damage with abnormal ankle brachial index (ABI) in high-risk hypertensive patients.MethodsDuring December 2008 to May 2009,a cross-sectional study was conducted to investigated the prevalence of abnormal ABI (ABI ＜ 0.90) in 2674 community-dwelling,hypertensive patients,who aged ＞ 40 years,without coronary heart disease,stroke/transient ischemic attack or known arteriosclerosis,from 18 centers in China. Data were acquired through history,physical examination,laboratory and other diagnostic tests.ResultsThere were 2615 subjects eligible for the full analysis set. The high-risk hypertensive patients with arterial wall thickening,arterial wall thickening and slightly elevated serum creatinine had a higher prevalence of abnormal ABI than their counterparts respectively ( P ＜ 0.05 ). Compared with the normal group,the abnormal ABI group had a higher serum creatinine level on average (P ＜ 0.01 ).After adjustment for certain factors including investigation center,demographic factors,cardiovascular disease (CVD) risk and CVD risk factors using an unconditional logistic regression model,arterial wall thickening ( OR 2.416,95％ CI 1.395-4.183,P =0.0016 ) and slightly elevated serum creatinine ( OR 3.377,95％ CI 1.267-8.997,P =0.0149) were positively associated with abnormal ABI. However,arterial wall thickening (OR 0.988,95％ CI 0.576-1.695,P=0.9664) and microalbuminuria (OR 1.389,95％ CI0.685-2.817,P=0.3621)were irrelevant to abnormal ABI.Conclusions So far as a high-risk hypertensive patient is concerned,there are significant statistical correlations between arterial wall thickening and/or slightly elevated serum creatinine and an abnormal ABI,but no significant statistical correlations between arterial wall thickening or microalbuminuria and an abnormal ABI is observed.

OBJECTIVE: To assess hearing effect of ossicular chain reconstruction with titanium ossicular replacement prosthesis during mastoidectomy with synchronous ossiculoplasty in chronic middle ear disease. METHOD: Retrospective reviews were performed for 139 patients who had underwent mastoidectomy and tympanoplasty with titanium ossicular replacement prostheses at the same time between 2008 and 2011. The partial ossicular replacement prostheses (PORP) were used in 91 patients and the total ossicular replacement prostheses (TORP) were used in 48 patients respectively. All patients had follow-up for 2 to 5 years. The preoperative and postoperative mean air conduction and air-bone gaps(ABG) for the four frequencies (0.5, 1.0, 2.0 and 4.0 kHz) were evaluated. The improvement of mean air conduction and ABG over the same frequencies were measured. A postoperative ABG less than or equal to 20 dB was considered a successful operation. The hearing results of titanium PORP and TORP were compared. RESULT: The mean air conductions were (53.97 +/- 11.32)dB and (36.80 +/- 11.68) dB preoperatively and postoperatively in PORP group. The mean improvement in air conduction was (17.17 +/- 5.79)dB. The mean ABG was (31.84 +/- 6.17)dB and (15.13 +/- 7.22)dB preoperatively and postoperatively in PORP group. The mean improvement in ABG was (17.71 +/- 5.5)dB. The difference of hearing threshold between preoperative and postoperative had statistical significance (P < 0.01). The mean air conduction were (58.05 +/- 11.35)dB and (44.53 +/- 13.15)dB preoperatively and postoperatively in TORP group. The mean improvement in air conduction was (13.52 +/- 7.81)dB. The mean ABG; were (35.67 +/- 5.73)dB and (21.48 +/- 7.01)dB preoperatively and postoperatively for TORP group. The mean improvement of hearing threshold in ABG was (14.18 +/- 7.53)dB. The difference of hearing threshold between preoperative and postoperative had statistical significance (P < 0.01). ABG less than 20 dB after operationwas happened in 68.63% of the patients (74.73% for PORP and 54.17% for TORP). There was statistically significant difference between PORP and TORP (P < 0.05). CONCLUSION We conclude that titanium ossicular reconstruction during mastoidectomy with synchronous ossiculoplasty give stable and excellent hearing results. We obtained better results with PORP than with TORP.
