AIM: To study the decomposition reaction kinetics of aqueous salvianolic acid B(Sal B). METHODS: HPLC was applied to determine Sal B's content of samples.Relationship between Sal B's content and heating time was regressed. RESULTS: Decomposition reaction of Sal B's aqueous solution was first order reaction.The effect of temperature on reaction rate of Sal B's decomposition was higher than pH value.At lower temperature(50℃),reaction rate constant K of Sal B's decomposition was very low and it changed very little with pH values. CONCLUSION: Water extraction process of Salvia Militiorrhiza should avoid applying high temperature,alkaline condition and long heating time in order to reduce loss and decomposition of Sal B,and then also increase Sal(B's) content in the extract.

Objective To evaluate the effect of sitaxsentan on renal microcirculation in beagle dogs undergoing cardiopulmonary bypass(CPB)when ultrasound microbubble angiography was used to monitor renal microcirculation.Methods Eighteen male Beagle dogs,weighing 10-15kg,aged 2-4 yr,were allocated into 3 groups(n=6 each)using a random number table:sham operation group(Sham group),CPB group and sitaxsentan group(S group).Sitaxsentan 0.7 mg/kg was infused over 30min starting from 1 h before CPB in group S.Before CPB(T1),at 1 h of CPB(T2),at the end of CPB(T3)and at 2h after the end of CPB(T4),the time-intensity curve of renal parenchyma perfusion was obtained using ultrasound microbubble angiography,and quantitative parameters including the slope rate of ascending curve(A),area under curve(AUC),derived peak intensity(DPI)and time to peak(TTP)were fitted.Results Compared with Sham group,the value of A was significantly decreased at T2-4,AUC and TTP were increased at T3,4,DPI was decreased at T4 in renal cortex and medulla in CPB group,and the value of A was significantly decreased and TTP was increased at T2-4,AUC was increased at T3,4(P<0.05),and no significant change was found in DPI in renal cortex and medulla in S group(P>0.05).Compared with CPB group,the value of A was significantly increased and AUC and TTP were decreased at T3,4 in renal cortex and medulla(P<0.05),and no significant change was found in DPI in renal cortex and medulla in group S(P>0.05).Conclusion Sitaxsentan can improve renal microcirculation in beagle dogs undergoing CPB.

Objective: To evaluate the efficacy of the third-generation instrumentation including TSRH, CD and ISOLA in the treatment of adult scoliosis. Methods:Thirty-five adult patients with idiopathic or degenerative scoliosis who received treatment with third-generation instrumentation (TSRH,CD and ISOLA) between July 1999 to January 2003 were retrospectively reviewed. The mean preoperative cobb angle of major curves of the frontal plane was 58.1°(42°-95°). The patients received a combined anteroposterior approach or a single posterior procedure. The mean follow-up time was 20 months(10-48 months). Preoperative and postoperative Cobb angles of the frontal plane and sagittal plane and the distance between C7 and CVLS were measured. The subjective assessment was judged by questionnaire. Results: Postoperative clinical appearance of all patients improved significantly. Mean correction of major curves of the coronal plane was 53.2%. Mean loss of correction of the coronal plane in the last follow-up was 4.3°. The distance between the midline of C7 and CVSL was corrected from 2.6 cm to 0.24 cm. The results of follow-up showed that 89.3% patients were satisfied with the outcome. Pneumatothorax and haematothorax occurred in 2 patients. Three patients still complained of low back pain one year after operation because of adjacent degeneration in 2 patients and pseudoarthrosis in the remaining 1 patient. Conclusion: Imageologic findings and subjective assessment of the patients showed that the third-generation instrumentation can achieve good correction and trunk balance in the treatment of adult scoliosis with fewer complications.

OBJECTIVETo observe the effect of Bushen Peiyuan Principle (BSPY, a TCM principle for tonifying Kidney and nourishing primordial energy) in treating patients with postmenopausal coronary heart disease (PCHD) instead of hormone treatment.

METHODSTwenty-five healthy women, who were monepaused for over 5 years but without CHD complication were allocated in Group A, 25 patients with PCHD complication suffered from estrogen contraindications such as embolism, hysteromyoma and mammary adenoma, were arranged in Group B, and 25 patients of PCHD without above-mentioned complications were divided into Group C. Group B and C was treated with BSPY and hormone replacement therapy respectively, and the drugs for hypolipidemics were withdrawn 1 month before the study. All the patients were observed for 3.5 months, with their blood levels of estradiol (E2) and lipids determined before and after treatment.

RESULTSBefore treatment, the level of E2 in the two treated groups was lower than that in the normal group significantly (P < 0.01), and the parameters of blood lipids were abnormal in them. These abnormalities were improved after treatment significantly (P < 0.05 or P < 0.01). The level of E2 raised significantly (P < 0.01) after treatment in patients of Group C, with withdrawal vaginal bleeding presented in 90% of less than 56 years in age. In the Group B after treatment, level of E2 showed a slight rising and withdrawal vaginal bleeding was not found but with improvement of symptoms and signs better than that in Group C.

CONCLUSIONUsing BSPY in treating PCHD displayed significant adjustment on disturbance of blood lipid spectrum and improvement on clinical manifestations. As compared with the therapeutic effect of hormone replacement therapy, the risk of carcinogenesis caused by endometrial hyperplasia could be avoided because the blood level of E2 is only slightly increased by BSPY.
