Objective By previous overview of patients treated in our hospital, this study highlights on the intervention effects of TCM treating principle of regulating liver Qi and tonifying kidney Yin on the adverse reaction of TAM on breast cancer patients in post surgery. Methods Perspective study with the measures of randomization, and paralleling and synchronization control was conducted in the research. Results symptoms such as flush, insomnia, night sweat, palpitation, depression and heat sensation in the chest, palms and soles were improved significantly; while manifestations such as nausea, vomiting, irregular menstruation, bitter taste and dry mouth showed no significant changes. QOL changed significantly. Conclusion The application of treating principle of regulating liver Qi and tonifying kidney Yin is effective in reducing side effects caused by TAM. This result further improved the theory of TCM that the nature of liver is active, although the liver belongs to Yin in physique and but Yang in function.

Objective The prospective study was trying to explore the altering tendency of plasma concentration of E2, P and PAS after TCM intervention for post-surgery breast cancer patient who received endocrine therapy (tamoxifen).Methods By randomization, parallel, coincidence measures and the lab. technologies of AXSYM registered at Abbott lab. in the USA, plasma concentration of E2, P and FAS were tested before and after treatment. Results The results of biochemical test of plasma E2, P and FAS concentration of the two arms showed no significance difference before and after the intervention,indicating the side effects relating to TAM had nothing to do with plasma E2, P and FAS level. Conclusion It could be predicable that there must be some other by-pass ways initiating breast cancer rather than the way directly altering the level of plasma concentration of E2, P and FAS.

Objective:To evaluate the value of adenosine triphophate (ATP)stress/rest nuclide myocardial perfusion imaging (MPI)in the diagnosis of female patients with coronary heart disease (CHD).Methods:The clinical materials of 47 female suspected CHD patients were retrospectively analyzed,aged from 39 to 74 years,and the average age was (53.7±6.3)years old.All patients were hospitalized and underwent two-day ATP stress and rest nuclide MPI and coronary angiography (CAG)in two weeks. The results and images of MPI and CAG were evaluated by more than 2 attending physicians. Using CAG as the “gold standard”, the diagnostic efficiency (sensitivity, specificity and accuracy) of MPI for CHD was evaluated. Results:Compared with CAG, the sensitivity,specificity and accuracy of ATP stress MPI in diagnosing the female CHD patients were 81.3% (13/16),77.4% (24/31)and 78.7% (37/47)individually;the positive predictive value and negative predictive value were 65.0% (13/20)and 88.9% (24/27).There were no severe adverse effects in the ATP stress test and the incidence of adverse effects was 85.1%.Conclusion:There is a highly diagnostic efficiency of ATP stress MPI in the CHD patients.It can be the first choice of examination methods for screening without injury and diagnosing the myocardial ischemia in the female patients.

Objective To investigate the relationship between hemodynamic parameters from quantitative analysis of contrast-enhanced ultrasonography (CEUS) on hepatocellular carcinoma (HCC) and pathological tumor differentiated grades. Methods Seventy-seven HCC lesions were examinated and off-line analyzed with dynamic images. Quantitative parameters such as slope of decrease to half of peak (SD), increased signal intensity (ISI), area under the curve (AUC) and blood flow coefficient (BF) were acquired, and the standardized values (sISI, sAUC and sBF) included the ratio of parameters from tumor to those from hepatic parenchyma. These quantitative parameters were correlated with tumor grades according to Edmonson criteria. Results There was significant difference (P＜0.05) of SD, AUC and BF, as well as standardized values (sISI, sAUC and sBF) between different grades of HCC. AUC, BF, sISI, sAUC and sBF were negative correlated with differentiated grades, respectively (P＜0.05). Well-differentiated HCC had significantly higher perfusion values than HCC of other grades (P＜0.05). Conclusion Quantitative analysis of CEUS can assess differentiation of HCC indirectly, and might reveal biological behavior of malignant tumors.

Objective To determine the dose?response relationship of bupivacaine coadministered with sufentanil for subarachnoid block in severely preeclamptic patients undergoing cesarean delivery. Methods Two hundred patients with severe preeclampsia, of American Society of Anesthesiologists physi?cal statusⅠ?Ⅲ, scheduled for elective cesarean delivery, were divided into 4 groups ( n=50 each) using a random number table: bupivacaine 4 mg group ( group B4 ) , bupivacaine 6 mg group ( group B6 ) , bupivacaine 8 mg group ( group B8 ) , and bupivacaine 10 mg group ( group B10 ) . In B4 , B6 , B8 and B10 groups, bupivacaine 4, 6, 8 and 10 mg plus 2.5μg sufentanil in 2.5 ml of normal saline were injected into the subarachnoid space, respectively. Effective anesthesia was defined as bilateral sensory block of T6 achieved at 10 min after intrathecal administration when measured by pin?prick test, and with no need for epidural supplementation ( lidocaine ) . A probit analysis was used to estimate the 50% effective dose ( ED50 ) and 95% effective dose ( ED95 ) with 95% confidence intervals for bupivacaine, coadministered with sufentanil, when used for subarachnoid block in severely preeclamptic patients underwent cesarean de?livery. Results When coadministered with sufentanil, the ED50 and ED95 ( 95% confidence interval) of bupivacaine were 5.67 ( 5. 20-6. 10) mg and 8. 82 ( 8. 14-9.87) mg, respectively, for subarachnoid block in severely preeclamptic patients underwent cesarean delivery. Conclusion The ED50 and ED95 of bupivacaine for subarachnoid block, when coadministered with sufentanil 2.5 μg, are 5.67 and 8.82 mg, respectively, in severely preeclamptic patients undergoing cesarean delivery.

Objective To evaluate the contrast-enhanced ultrasonography (CEUS) in quantitative diagnosis of chronic renal insufficiency. Methods Correlation of CEUS indexes with glomerular filtration rate (GFR) detected by 99mTc-DTPA renography was examined. Thirty-three cases of clinical chronic renal insufficiency were enrolled in the study. They were 15 males and 18 females with average age of (43.33±6.78) years. After intravenous bolus injection of 1 ml SonoVue,CEUS of renal cortex blood perfusion was performed successfully, and a time-intensity curve (TIC)was created with PHILIPS iU22 system's QLAB software. A 148 to 222 MBq dose of 99mTc-DTPA was injected as a bolus from antecubital vein. Renal scintigraphic images were collected immediately and GFR was obtained. Results The significant correlation coefficients between GFR and CEUS quantitative indexes were as follows: rAUC (area under curve)=0.886 (P＜0.05), rA (slope rate of ascending curve, A) =0.804(P＜0.05). However, rDPI (derived peak intensity, DPI)=0.021 (P＞0.05), rTTP (time to peak, TTP) =0.043 (P＞0.05), rα (slope rate of descending curve,α)=0.039 (P＞0.05). Conclusion CEUS can precisely display the hemodynamic change of chronic renal insufficiency, which is well correlated with GFR by 99mTc-DTPA renography.
