PurposeTo explore the left ventricle flow propagation process in patients with chronic heart failure (CHF) using velocity flow mapping. Materials and Methods Patients with CHF (n=25) were selected as CHF group. Healthy subjects (n=28) were chosen as the control group. Flow reversal interval (FRI), flow reversal rate (FRR), corrected flow reversal rate (CFRI) and flow rate in peak ejection (FRPE) were measured. Parameters related to the vortex in CHF group were compared with that in the control group. Results Compared with the control group, FRI was longer [(71±13) msvs. (113±30) ms, P<0.05], FRR and FRPE were lower [(46.85±21.35) cm2/svs. (27.90±16.77) cm2/s;(74.54±9.10) cm2/svs. (41.12±17.25) cm2/s,P<0.05] in CHF group. FRI and CFRI were positively correlated with the Tei index (r=0.812 and 0.849,P<0.01). FRI was negatively correlated with LVEF, FS, SV, CO, CI (r=-0.646--0.515,P<0.05 orP<0.01). CFRI was negatively correlated with LVEF, FS, SV, CO and CI (r=-0.685--0.456,P<0.05 orP<0.01); FRR was negatively correlated with Tei index (r=-0.604,P<0.05), and was positively correlated with LVEF, FS, SV, CO and CI (r=0.503-0.812,P<0.05 orP<0.01);FRPE was negatively correlated with Tei index (r=-0.734,P<0.01), and were positively correlated with LVEF, FS, SV, CO and CI (r=0.557-0.776,P<0.05 orP<0.01).Conclusion Velocity flow mapping can demonstratecardiac hydromechanics in patients with chronic heart failure. The heart blood flow direction reversal efficiency may be a new method for diagnosis and treatment evaluation.

Objective To explore the clinico-biological characteristics, treatment and prognosis of salivary duct carcinoma. Methods This study included 12 cases of salivary duct carcinoma treated in our hospital. Clinical data were retrospectively analyzed for patients admitted between April 1995 and October 2006. The clinical characteristics, histological features, imaging, therapy methods and prognosis were analyzed. Results Of 12 salivary duct carcinoma, there were 10 males, 2 females. The age of onset ranged from 53 to 73 year old and the average was 56 year old. Physical examination revealed a firm and unboundary mass accompanied by nerve infiltrating symptom. The histological appearance was characterized by solid cell nests with ductal structures and central comedonecrosis. Extensive resection and radical neck dissection was performed in 11 patients, postoperation radiation done in 10 patients and chemotherapy in 3 patients. One year survival rate was 83. 33% , that of 3 years was 41. 67% , and of 5 years was 25. 00% , the median survival time was 36 months. Conclusion Salivary duct carcinoma is a rare malignant salivary tumor and most patients are men. Regional extensive resection and postoperative radiation or chemotherapy are the mainstay of therapy. Lymph node metastases in level Ⅰ ,Ⅱ , Ⅲ are a common finding in patients with SDC and the prognosis is poor.

AlM:To study the treatment effect of traditional Chinese medicine in the treatment of high myopia macular hemorrhage, using Chinese medicine etiology and pathogenesis, syndrome differentiation treatment, and provide the basis for the clinical treatment. METHODS: Eighty patients ( 135 eyes ) with high myopia macular hemorrhage were selected in the hospital from January 2012 to september 2014 as treatment group, and applied traditional Chinese medicine treatment. Forty-five patients (64 eyes) with the same period, as the control group, received routine western medicine treatment. After 1mo treatement, the treatment effect and vision improvement situation of two groups were observed, and after 6mo follow-up, the relapse was observed.RESULTS: The total effective rate of treatment group was 85. 19% (115/135), higher than the control group 78. 13% (50/64) (P<0. 05). The average corrected visual acuity of treatment group was 0. 48±0. 11, higher than the control group 0. 36 ± 0. 09, the difference was statistically significant (P<0. 05). The average diopter and macular bleeding scope of the treatment group were -9. 81±0. 85D and 0. 51 ± 0. 27PD, lower than the control group -10. 76 ± 0. 91D and 0. 78 ± 0. 23PD, the differences were statistically significant ( P < 0. 05 ). The eye ground hemorrhage absorption time of treatment group was 25. 34±2. 28d, less than the control group 29. 72 ± 2. 13d, the difference was statistically significant (P<0. 05). The bleeding again of the control group 7. 81% ( 5/64 ), higher than the treatment group was 5. 19% (7/135), the difference was statistically significant (P<0. 05).CONCLUSlON: Evidence-based treatment of traditional Chinese medicine for high myopia macular hemorrhage has good clinical effect, can shorten the treatment time, and is beneficial to the recovery of postoperative vision, worthy of clinical popularization and application.
