Objective To evaluate the left ventricular diastolic dysfunction by tissue Doppler imaging (TDI)in a suprarenal abdominal aortic coarctation model of Lewis rats. Methods Thirty male Lewis rats at age of 8 weeks were used. Myocardial hypertrophy model was obtained by suprarenal abdominal aorta banding with ligation. Mitral annular velocity measurement by TDI and regular two-dimensional echocardiography with M mode were examined at baseline and at 10-,20-,30-and 40-day post banding.Results Compared with baseline,the left ventricular end diastolic and end systolic wall thickness and ventricular dimension were progressively increased,while ejection fraction(EF)and fraction shortening(FS)were decreased(P＜0.0 1).The left ventricle demonstrated centrifugal myocardial hypertrophy.Peak myocardial systolic velocity(Sa)at the mitral annulus did not change significantly throughout this study and there was no significant correlation with EF(r=0.216,P=0.071),and peak myocardial early diastolic (Ea),late diastolic(Aa)at the mitral annulus and Ea/Aa indices also were not stable after aortic banding and there were no significant difference in repeated measures at different time(P＞0.05).But the E/Ea wasincreased and the index had a statistically significant difference(P＜0.001).Conclusions The left ventricleshowed centrifugal myocardial hypertrophy in Lewis rats with abdominal aortic banding.E/Ea radio was a sensitive and stable index to evaluate left ventricular diastolic dysfunction.

Objective Evaluation of the effect of manual reduction with small external fixation on the treatment of elderly Barton fractures.Methods A total of 244 elderly patients with Barton fractures were divided into conservative group (n=126) and operation group (n=118) according to random number table. The conservative group was treated by with manual reduction with small external fixation, and the operation group was treated with open reduction and internal fixation. The complications of the patients, the time of fracture healing, hospitalization time and treatment cost were recorded.The wrist function was evaluated by PRWE wrist score system and Wrightington wrist function score system.The clinical efficacy was evaluated by Gartland-Werley Colles fracture evaluation method.Results The excellent and good effect rate was 91.3% (115/126) in the conservative group and 97.5% (115/118) in the operation group. There was no significant difference between the two groups(χ2=0.857,P=0.354). One year, 6 months, 3 months and 6 weeks after treatment, in the conservative group, the PRWE score (10.4 ± 7.9, 19.1 ± 8.0, 40.5 ± 7.8, 55.7 ± 8.1vs. 80.8 ± 8.2,F=113.665), wrightington score (8.2 ± 3.7, 13.2 ± 4.0, 21.4 ± 3.9, 26.3 ± 4.2vs. 30.1 ± 4.2,F=121.348) were significantly lower than those before treatment (P<0.01). And in the operation group, the PRWE score (10.2 ± 7.8, 15.0 ± 8.0, 26.5 ± 8.0, 44.7 ± 8.2vs. 79.6 ± 8.6,F=81.411), Wrightington score (8.1 ± 3.8, 12.1 ± 4.0, 16.5 ± 4.0, 20.6 ± 4.3vs. 29.8 ± 4.6,F=69.113) were significantly lower than those before treatment (P<0.01). But there was no significant difference in PRWE score and Wrightington scores between the two groups after treatment (t=0.149, 0.104,P=0.881, 0.917, respectively). In the conservative group, the hospitalization time (5.28 ± 2.10 dvs. 12.8 ± 2.21d,t=25.260) was significantly shorter than that of the control group (P<0.01), and the treatment cost (3.26 ± 0.93 thousandvs. 28.66 ± 1.04 thousand,t=200.369) was significantly lower than that in the control group (P<0.01). The overall incidence of complication was 8.7% (11/126) in the conservative group and 17.8% in the surgery group (21/118). There was significant difference between the two groups(χ2=4.396,P=0.036).Conclusions The manual reduction with small splint external fixation was simple, low cost, small trauma, short hospitalization time, and less complications.

Objective To compare the effects and complications of lumboperitoneal shunt ( LP ) and ventriculoperitoneal shunt ( VP ) in the treatment of post?traumatic hydrocephalus. Methods Eighty patients with post?traumatic hydrocephalus treated in the neurosurgery department of Zhangjiagang Hospital of Traditional Chinese Medicine from March 2014 to March 2010 were retrospectively analyzed. The patients were randomly divided into two groups,40 patients treated with LP were assigned into the LP group and 40 patients undergone VP treatment were seen as the VP group. All patients were followed up for 1 year to investigate and compare the symptom improvement rate,neurological deficit score and the incidence of complication of the two groups. Results The total effective rate of hydrocephalus disappearance in the LP group was 41. 50% ( 37/40) and 87. 50%( 35/40) in the VP group. The difference between the two groups was not statistically significant (χ2=0. 556,P=0. 456);the neurological deficit scores before treatment in the LP group and VP group were (28. 35±8. 64) points and (29. 13±7. 98) points,there was no significant difference between the two groups (t=0. 419,P=0. 676) . The difference in the scores of neurological deficit after treatment in the LP and VP group was not statistically significant ( (19. 32±5. 34) points vs. (21. 62±4. 86) points,t=1. 480,P=0. 143),the average scores of neurological deficits in the two groups were significantly better than those before treatment ( t=5. 623, 5. 084,P<0. 001 ) . There was no significant difference in the average score of improvement of urinary incontinence between the two groups before and after treatment ( t=0. 376,1. 265,P>0. 05) ,the average score of urinary incontinence improvement after treatment in both groups were better than those before treatment ( t=4. 891,5. 370,P<0. 001) . In the LP group,the incidence of bleeding,infection,shunt related complications and shunt abnormality were all 2. 50% ( 1/40 ) , the overall complication rate was 10. 00%, the incidence of bleeding,infection,shunt related complications and shunt abnormality in the VP group were 7. 50% (3/40), 10% ( 4/40 ) , 5% ( 2/40 ) 10%, ( 4/40 ) , the overall complication rate was 32. 50%, there was significant difference between the two groups (χ2=6. 050,P=0. 014) . Conclusion LP and VP have significant curative effect on the treatment of post?traumatic hydrocephalus,but the overall incidence of LP complication after 1 year is significantly lower than that of VP,and is worth popularizing widely in clinical practice

Objective To observe the effect of Chinese herbal fumigation combined with CPM promote the function recovery after Postoperative Patellar Fracture. Methods Eighty patients with patellar fracture were randomly divided into treatment group (40 cases) and control group (40 cases). The control group was treated with CPM. The treatment group was treated with Chinese Herbal Fumigation and CPM. After 8th weeks, the clinical curative effect, knee range of motion and KSS knee score were observed and compared. Results The effect rate of the treatment group was 87.5% (35/40), and the control group was 65.0% (26/40). The difference was statistically significant (χ2=5.591, P<0.01). After treatment, the range of motion of knee joint (138.38°± 7.82°vs. 0.29°± 7.83°, t=10.338), KSS knee function score (88.38 ± 9.52 vs. 3.46 ± 9.36, t=2.330) of the treatment group were higher than those in the control group (P<0.01 or P<0.05). Conclusions The Chinese medicine fumigation combined with CPM functional exercise could accelerate the recovery of knee function and reduce the complications of fracture after patellar fracture.

Objective: To explore the occurrence rate of permanent pacemaker implantation (PPI) with relevant risk factors in patients after mechanical aortic valve replacement. Methods: A total of 1986 consecutive patients with mechanical aortic valve replacement were enrolled in this study. According to PPI conduction caused by severe arrhythmia , the patients were divided into 2 groups: PPI group,n=61 including 27 male with the average age of (53.6 ± 9.03) years and Non-PPI group,n=1925. The median follow-up time was (4.47 ± 4.36) years after valve replacement. Results: The patients in PPI group were with the elder age and higher ratio of pre-existing atrial ifbrillation (AF) than those in Non-PPI group,P<0.05. The overall PPI occurrence rate was 3.07% after valve replacement and the short term incidence rate (within 30 days) was 0.55%, midterm (from 30 day to 1 year) was 0.03%, long term (>1 year) was 2.22%. For PPI indications, there were 70.5% patients with high degree A-V block including 30 of AF combining long intervals, 12 of high degree A-V block, 1 of complete left bundle branch block (LBBB) and 14.8% patients with sick sinus syndrome/sinus arrest/ sinus bradycardia. Conclusion: PPI incidence was at a relative low level, the long term occurrence rate was higher than both short term and midterm; elder age, pre-existing AF could be the high risk factors for PPI requirement, and the major PPI indication was high degree AV block in clinical practice.

Objective: To retrospectively analyze the ascending aortic diameter (AAD) changes in patients after mechanical aortic valve replacement (AVR).
Methods: The medical records and echocardiography reports in patients who received AVR or bivalve valve replacement (BVR) in our hospital from 2000-01 to 2001-12 were retrieved, the retrieval conditions were as aortic valve structure must be mechanical and the follow-up echocardiography examination should be more than 9 years. The clinical information, pre- and post-operative 2-dimentional transthoracic echocardiography reports were collected, the follow-up echocardiography periods were ≤3-year, 3-year<-≤6-year, 6-year<-≤9-year and >9-year. AAD changes at different periods were compared. According to baseline AAD, the patients were divided into AAD<35 mm group and AAD≥35 mm group in order to observe the ascending aortic events.
Results: A total of 141 patients were enrolled form 595 echocardiography reports which included 75 male, the patients were at the mean age of (45.5 ± 11.2) years with mean follow-up time of (7.59 ± 3.38) years. Compared with baseline level, the follow-up AAD was similar between ≤3-year and 3-year<-≤6-year patients,P>0.05; while the follow-up AAD was different between 6-year<-≤9-year and >9-year patients,P<0.05. The patients with second operation in AAD≥35 mm group were much higher than those in AAD<35 mm group (24.0% vs 12.9%). There were 5 (20%) patients suffered from ascending aortic events in AAD≥35 mm group.
Conclusion: AAD dilatation were gradually occurring after mechanical AVR, the patients with AAD≥35 mm had the higher risk for ascending aortic events, therefore special attention should be taken in patients with aortic valve disease combining AAD dilatation during surgical treatment.

Objective: To explore the clinical, pathological and echocardiographic characteristics of rare primary non-mucinous cardiac tumor (PNCT) and to investigate the diagnostic value of echocardiography in benign and malignant PNCT with various pathological classiifcations. Methods: We retrospectively studied 32 PNCT patients including 21 benign and 11 malignant patients treated in our hospital from 2003-01 to 2013-02. There were 23 male and 9 female from 0.5 to 66 (36.92 ± 20.17) years of age. We analyzed the clinical information of echocardiography, CT, MRI and operation, and the ifndings were conifrmed by pathology. Results: Statistic analysis presented that there were more male PNCT patients than female, the ratio of male/female in benign patients was 16/5, in malignant patients was 7/4, P<0.05, the age was similar between 2 groups, (38.06 ± 21.68) years vs (35.72 ± 13.55) years,P>0.05, and either infant or adult could suffer from PNCT. Benign PNCT was more in left heart and malignant PNCT was more in right heart. Compared with benign PNCT, malignant lesions were usually no base, with irregular shape, pericardial effusion and surrounding tissue adhesion. Conclusion: Echocardiography was sensitive for diagnosing the patients with PNCT, it could preliminarily identify benign and malignant lesions with different ultrasonographic manifestation.
