Objective To investigate static closure functional characteristics of lower urinary tract in continence in late pregnancy of primigravida through perineal ultrasound and urodynamieal measurement. Methods From January of 2003 to December of 2005,83 primigravida undergoing antenatal health care in Shanghai Jiaotong University Affiliated Shanghai Sixth People's Hospital were randomly enrolled in the study, while 28 nulliparous women were recruited as control.The perineal ultrasound and urodynamical measurement were performed at the gestation age of 36-40 weeks,in both groups.We analysed the parameters of lower urinary tract function in late pregnancy compared with nullipara,such as maximal urethral closure pressure(MUCP),functional urethral length(FUL),maximal urethral pressure(MUP), valsalva leak point pressure(VLPP),postvoid residual bladder volume(PVRBV)and volume of first desire to voiding(VFDV).Results The average weight of 83 neonates was(3504?404)g.In all of 83 primigravida PVRBV was less than l0 ml.MUP(110 + 22)cm H_2O(1 cm H_2O=0.098 kPa),MUCP (96?22)cm H_2O and FUL(44?9)mm were significantly increased in the third trimester compared with nullipara(P0.05). There were 33 pregnant women suffering from urinary leakage throughout the terms.The data showed that MUCP was significantly lower in the pregnant women with symptoms of leaking than without leaking. Conclusion The static closure function increased significantly compared with nulliparous women.The VLPP was decreased and had relationship with symptoms of leakage.The results suggest that the function of lower urinary tract in continence in late pregnancy of primigravida is complex.

OBJECTIVE: To evaluate the uptake characterizations of berberine, palmatine and jateorhizine through hepatic uptake model with rat primary hepatocytes. METHODS: Rat hepatocytes were isolated by Seglen's two-step method and cultured in suspension. The activity of transporters was assessed using rosuvastatin which is known as the substrate of the transporters. The tested drugs were incubated with rat hepatocytes at 4 or 37℃ for various periods of time and the drugs were determined using UPLC-MS/MS method to calculate the uptake amounts. The effect of cultural time and temperature on the hepatic uptake of these compounds were assessed. The kinetic parameters such as Km, Vmax and CLactive/CLuptake were calculated from concentration dependent uptake experiments. The effects of positive inhibitors on the uptake of berberine, palmatine and jateorhizine were also surveyed by pre-incubation of the inhibitors with the rat hepatocytes, followed by co-incubation with berberine, palmatine and jateorhizine. RESULTS: The hepatic uptake of berberine, palmatine and jateorhizine increased along with the increase of concentration at 37℃ while the change of hepatic uptake was very little at 4℃. The value of CLactive/CLuptake was 85.26%, 74.90% and 57.74% for berberine, palmatine and jateorhizine. Ibuprofen, digoxin, glycyrrhizin and prazosin which were the known inhibitors of transporters could remarkably reduce the hepatic uptake of berberine and palmatine, respectively. Glycyrrhizin and prazosin could reduce the uptake of jateorhizine. CONCLUSION: The transport of berberine, palmatine and jateorhizine into hepatocytes is mainly through an active process. Berberine and palmatine are the substrates of Oatp1a1, Oatp1a4, Oatp1b2 and Oct1, and the uptake of jateorhizine might be associated with Oatp1b2 and Oct1.

Partial nature of "promoting blood circulation and dieresis" of Salvia Miltiorrhizain was initially demonstrated by investigating the regulation effect of AQP2 expression in kidney of trauma blood stasis model rats with the Salvia Miltiorrhizain so as to provide guidance for its clinical deployment of administration. Random allocation was taken to averagely divide 30 SD rats into two groups: 10 rats in normal group and 20 rats in blood stasis syndrome group. Trauma blood stasis rat model was established by quantitatively beating. Then the rat model group was divided into model group and salvia group. After 7 days of treatment, the rat kidney AQP2 expression was detected, the content of urine AQP2 was compared and the damaged local muscle and kidney pathological changes were observed by immunohistochemical method and western blot method. Compared with that of the normal group, rats in model group had inflammatory cells infiltration, blood stasis and edema of the injured local muscles and up-regulated AQP2 expression, decreasing urinary output, and kidney tissues blood stasis and edema (P < 0.05). On the other hand, compared with that of the model group, those parameters of rats in salvia group were all decreasing except urine output (P < 0.05). Such result indicated that Salvia Miltiorrhiza can reduce trauma blood stasis rat content of urine AQP2 and down-regulated AQP2 expression in kidney tissue, so as to reduce the reabsorption of water by renal tubular and increase urine output. The promoting blood circulation effect of Salvia Miltiorrhizain can alleviate the degree of the damaged tissue edema and encourage urine drainage. This therapy is closely related to the effect of regulating AQP2 in kidney by salvia, so the purpose of this study by verifying "promoting blood circulation and diuresis" as the mechanism for the regulation effect of the salvia on AQP2 expression.

Objective To analyse the breast conserving surgery feasibility in patients with advanced breast cancer after neoadjuvant chemotherapy.Methods Sixty patients with advanced breast cancer were collect-ed from June 2010 to June 2011, and were divided into breast conserving surgery after neoadjuvant chemotherapy group and modified radical mastectomy group according to the intention,30 cases in each group.They were given breast conserving surgery after neoadjuvant chemotherapy and modified radical mastectomy respectively,with fol-lowing-up for 3 years.The treatment effect and contrast analysis of two groups of breast cancer CTCs positive of the two groups were compared,two groups of late follow-up of patients with local recurrence and distant metasta-sis rate,overall survival and disease free survival rate were recorded.Results Compared with the modified radi-cal mastectomy group,CTCs detection rate in breast conserving surgery group had no statistical differences(P>0.05).Two groups of patients in clinical complete remission rate,partial remission rate,disease stability factor and local recurrence and distant metastasis rate,overall survival and disease free survival rate had no statistical significances(P>0.05).Conclusion The application of breast conserving surgery after neoadjuvant chemother-apy for patients with advanced breast cancer can achieve similar effect as modified radical mastectomy surgery treatment,and can be used as a effective treatment for advanced breast cancer.

It is held by some of the researches that the "16 collaterals" is composed of the "15 collaterals" and "the major collateral of stomach". And it is included into the textbook that Xuli, the major collateral of stomach, is the pulsation point at the cardiac region. Xuli is often explained as the empty portion of the human body by many researches. Through analysis and summarization of the related theory of the major collateral of stomach, the above mentioned opinion is discussed. And the understanding on the major collateral of stomach is deepened. As a result, it is concluded that count the major collateral of stomach into the 16 collaterals together with the 15 collaterals is inadvisable. The real pulsation point at the cardiac region locates under the left breast. And the real meaning of Xuli is "extending in all directions".
