Objective To assess the clinical significance of three-dimensional speckle tracking imaging (3D-STI) in the evaluation of left ventricular myocardial function in breast cancer survivors with postoperative anthracycline-based chemotherapy.Methods A total of 51 breast cancer survivors with postoperative anthracycline-based chemotherapy were recruited and 31 female healthy volunteers as the controls.Conventional echocardiography and 3D-STI derived parameters [including global longitudinal strain (GLS) and global area strain (GAS)] were measured before and at 3 and 6 anthracycline-based chemotherapeutic cycles.The receiver operating characteristics (ROC) curve was constructed to determine optimal sensitivity and specificity of 3ID-STI derived parameters for the prediction of future cardiotoxicity.Results In comparison with the controls and baseline cases,GLS and GAS deteriorated significantly (P ＜ 0.05 for both).No statistical difference in GCS and conventional parameters showed before and after the initiation of chemotherapy (P ＜0.05,respectively).The ROC curves showed that GAS as the best 3D-STI predictor of patients who develop cardiotoxicity during the follow-up.The area under ROC(AUC) of GAS was 0.894,and its optimal cut-off value was-28.4％,with a specificity of 88.0％ and a sensitivity of 82.9％.AUC of GLS was 0.802,and its optimal cut-off value was-14.3％,with a specificity of 62.0％ and a sensitivity of 85.4％.Conclusions Early decreases in GAS and GLS based on 3D-STI may allow the prediction of subsequent cardiotoxic development accurately in breast cancer survivors with postoperative anthracycline-based chemotherapy.

Objective To evaluate the safety,local efficacy and survival rates of isolated pulmonary metastases from colorectal carcinoma treated with CT-guided radiofrequency ablation.Methods A total of 28 patients with isolated pulmonary metastases from colorectal carcinoma were performed with CT-guided radiofrequency ablation (radiofrequency ablation group).The size of the lesion was 1.2-5.0 (2.9 ± 1.0) cm.During the same time,9 patients,who did not take any treatment for isolated pulmonary metastases from colorectal carcinoma,were collected as control group.The size of the lesion was 2.0-5.0 (3.6 ± 1.0) cm.The local progression-free rates and overall survival rates were compared.Results All the cases were able to complete the radiofrequency ablation in radiofrequency ablation group.During and after the procedure,no major complications occurred.The 1-,2-,and 3-year local progression-free rates and overall survival rates in radiofrequency ablation group were significantly higher than those in control group.The local progression-free rates were 89.3％ vs.76.2％,78.6％ vs.33.9％,70.7％ vs.16.9％.The overall survival rates were 96.4％ vs.77.8％,85.7％ vs.44.4％,56.7％ vs.22.2％.The differences between two groups had statistical significance (P ＜ 0.01).Conclusion CT-guided radiofrequency ablation for isolated pulmonary metastasis from colorectal carcinoma is a safe,effective,minimally invasive treatment,and can significantly improve the local progression-free rates and overall survival rates.

Objective: To give the living-donor and recipient medical evaluation and moral evaluation pretransplant by Academic and Ethics Committee for Organ Transplantation (AECOT), ensure the transplantation proceed smoothly and the feasibility for moral principles. Methods:AECOT was formed and gave the living-donor and recipient medical evaluation, additional moral evaluation to their family, evaluated the possibility for transplantation, ensured the long-dated safety for living-donor and recognition for ethics, ensured the transplantation proceed successfully. Results: 18 cases were evaluated by AECOT, two cases had the operation refused because of the II-diabetes for one living-donor and the other living-donor refused evaluation, one case had the operation delaied because of the overweight for the living-donor. The rest 15 cases were accepted operation smoothly,both donor and recipient recovered well post transplant. Conclusion:Academic and Ethics Committee for Organ Transplantation(AECOT) is a essential agency for Living Donor Kidney Transplantation.

The medium of photo-synthetic bacteria synthesizing carotenoid was optimized with response surface methodology. The regression equation expressing the relationship between carotenoid yield and main components of culture medium was established by stepwise analysis. The R-squared in the model of regression equation was 0. 958, which meant the established equation could predict the carotenoid yield well at the range of factors in this design. It was indicated that the optimum medium components were: 0. 81% citric acid, 0. 35% NH4Cl and 0. 18% corn syrup. On those conditions, it was predicted that the highest production of carotenoid was 13. 34 mg/L, which was 2. 04 times higher than initial carotenoid yield before optimization.

OBJECTIVETo observe blood uric acid levels and Goldstein grading, as well as their correlation in Wilson's disease (WD) patients with different Chinese medical syndrome types.

METHODSTotally 906 WD patients in line with inclusive criteria were assigned to 6 groups, i.e., the heart spirit confused by phlegm group (HSCP, 26 cases), the phlegm-fire disturbing heart group (PFDH, 90 cases), the retention of damp-heat group (RDH, 113 cases), deficiency of qi and blood group (DQB, 168 cases), the deficiency of Gan-yin and Shen-yin group (DGYSY, 327 cases), the deficiency of Gan and Shen group (DGS, 182 cases) due to different Chinese medical syndrome types. Recruited were another 160 healthy subjects having similar ages and diet structures, who came for medical examinations, as the healthy control group. Venous blood was collected from the medial cubital vein of each-patient on an empty stomach in early mornings to detect blood uric acid levels. Results Blood uric acid levels were lower in each syndrome type group than in the healthy control group (146.08 +/- 67.24 micromol/L in the HSCP group; 157.08 +/- 69.77 micromol/L in the PFDH group; 162.58 +/- 97.72 micromol/L in the RDH group; 156.20 +/- 62.63 micromol/L in the DQB group; 161.83 +/- 111.23 micromol/L in the DGYSY group; 194.41 +/- 90.01 micromol/L in the DGS group; 242.39 +/- 87.55 micromol/L in the healthy control group, P < 0.01). Blood uric acid levels were higher in the DGYSY group than in the other 5 syndrome groups (P < 0.01). Correlation analyses between Goldstein grading and blood uric acid showed that, along with increased Goldstein grade (that was aggravating disease conditions), WD patients' blood uric acid levels decreased (P < 0.01).

CONCLUSIONSWD patient's blood uric acid levels decreased more. Blood uric acid levels and Goldstein grading were different in various Chinese medical syndrome types. Blood uric acid levels had certain value in assessing the severity of WD.

OBJECTIVETo observe the effect of a integrative medical regimen (IMR), i.e. combined use of Jiangya Capsule (JYC) and Nimodipine (ND), on blood pressure, TCM clinical symptoms, and blood levels of vascular endothelial function and hypersensitive C-reactive protein (hs-CRP) in elderly patients with isolated systolic hypertension (EISH).

METHODSAdopting randomized, double-blinded and controlled principle, a trial was conducted on 135 patients with EISH by randomized them into three groups, they were administered IMR (Group A), JYC plus ND simulator (Group B) and ND plus JYC simulator (Group C) respectively, for 4 weeks. Changes of blood pressure and TCM symptoms, as well as the levels of serum nitric oxide (NO), plasma endothelin-1 (ET-1), 6-keto-prostaglandin 1alpha (6-keto-PGF(1alpha)), thromboxane B2 (TXB2) and hs-CRP were observed before and after treatment.

RESULTSAfter treatment the systolic blood pressure reduced and clinical symptoms improved, with serum NO and 6-keto-PGF(1alpha) lelels elevated, plasma ET-1, TXB2 and serum hs-CRP decreased in all the three groups (P<0.05 or P<0.01). But the inter-group comparisons showed that the effect in Group A was superior to the other two groups in decreasing systolic pressure, and superior to Group C in improving clinical symptoms, elevating serum NO and decreasing plasma TXB2 (P <0.05).

CONCLUSIONThe integrative medical regimen of combined use JYC and ND has markedly effect in lowering blood pressure, it could obviously improve the symptoms and vascular endothelial function, and inhibit the level of inflammatory factor in patients with EISH.

Objective To analyze C4d deposition in the patients with late acute renal allograft rejection,and explore the role of C4d in grafts survival and grafts loss. Methods Thirty-six patients clinical and pathologically diagnosed as having acute rejection more than one year post-transplant were selected. C4d was detected by immunohistochemistry in renal allograft biopsies. The effect of C4d deposition on long-term graft survival was studied. Results Among 36 recipients with late acute renal allograft rejection, 16 cases were positive for C4d (44.4 %) and 20 negative for C4d (55.6 %). Five cases experienced graft loss in C4d positive group (31.3 %), while 6 cases in C4d negative group (30.0%). There was no significant difference in the graft loss rate between C4d-positive group and C4d-negative group. Log-Rank test demonstrated there was no significant difference in graft survival between C4d-positive group and C4d-negative group. The count of the interstitial infiltrated eosinophils in renal allograft was (9.4 + 4.5) and (2.6 + 1.8) respectively in the C4d-positive group and C4dnegative group (P＜0.05). Conclusion C4d deposition in peritubular capillary of the recipients with late acute renal allograft rejection might not be a prognostic marker for graft outcome.

Objective To investigate the left ventricular (LV) performance in patients with essential hypertension(EH) by global performance index (GPI) based on three-dimensional speckle tracking imaging (3D-STI).Methods A total of 164 EH patients were enrolled and divided into four subgroups according to LV configuration:LV normal group (LVN,n =67),concentric cardiac remodeling group (CCR,n =49),concentric cardiac hypertrophy group (CCH,n =28) and eccentric cardiac hypertrophy group (ECH,n =20).Thirty age and sex matched healthy volunteers were enrolled as controls.3D-STI was performed to assess LV 3D global strain and LV torsion,then LV systolic dyssynchrony index (SDI) and global performance index (GPI) were calculated.Global strain parameters were investigated among the groups,and correlations with GPI were studied.Results GPI,global longitudinal strain(GLS),global area strain(GAS),global radial strain(GRS) and global 3D strain(G3DS) in EH groups were respectively lower than those in the normal controls,and there were statistical differences among the respective parameters (P ＜0.05,respectively).SDI in group CCH and ECH were significantly higher than that in normal controls (P ＜ 0.05,respectively).In multivariate stepwise regression analysis,GAS was the most influential to GPI.Conclusions GPI based on 3D-STI may accurately reflect LV performance in patients with EH,and has potential applications in clinical practice.
