To prepare beta-cyclodextrin (beta-CD)-deoxyrhaponti inclusion complex by the homogeneous method, and characterize the inclusion complex with ultraviolet-visible spectrum and fluorescence spectroscopy, in order to determine the inclusion rate, the ratio of subject-object, the binding constant of supra-molecular system and the thermodynamic function. The results showed that the designed method was so rational that the inclusion complex was successfully prepared. The ultraviolet-visible spectrophotometry method was adoptedto determine the inclusion rate of 38%, and the ratio of subject-object of 2: 1. The thermodynamic parameters of this inclusion complex: deltaH(0), deltaS(0) was all smaller than zero, which indicated that the main acting forces generated by the inclusion complex were hydrogen bonding and Vander Waals' force. deltaG(0) < 0 and deltaG(0) were directly proportional to the reaction temperature, which suggested that the reaction would spontaneously increase with the temperature rise. The polarization fluorescence method was used to quantitatively prove the non-covalent inclusion complex generated during the interaction between beta-CD interacting with DES. The results could also provide reference for studies on cyclodextrin supra-molecular system.

Objective To explore the incidence and risk factors of acute kidney injury (AKI) following hepatic arterial chemoembolization inpatients with hepatocellular carcinoma(HCC),Child class A. Methods Retrospective analysis was performed on patients with HCC,Child Class A who were admitted from January 2008 to October 2016.The inclusion criteria:(1) patients were diagnosed with pathologically confirmed hepatocellular carcinoma based on the standards of primary liver cancer diagnosis and treatment (2011 edition);(2) patients have complete laboratory parameters and imaging data within the 7 days before the TACE treatment;(3) the Child-pugh score was 5 to 6;(4) patients have no acute or chronic renalfailure before the treatment of TACE.The morbidity of AKI after TACE was investigated.Twenty-six factors such as age,sexy,contrast dose,hemoglobin were included as independent variable, so as to investigate the risk factors for postoperative AKI. Results A total of 818 patients were included in the study, including 38 experiencing postoperative AKI(4.64%).Multivariate logistic regression analysis identified elevated preoperative uric acid as the independent risk factor for postoperative AKI(OR=1.005,95% CI 1.000 to 1.009,P=0.037), and elevated preoperative hemoglobin as the protective factor for postoperative AKI(OR=0.974,95% CI 0.952 to 0.997,P=0.028).Conclusions AKI is not uncommon following hepatic arterial chemoembolization inpatients with HCC,Child Class A,and is correlated with elevated uric acid and anemia.Preoperative risk assessment and anemia correction might be effective for reducing the incidence of AKI following hepatic arterial chemoembolization.

OBJECTIVETo reveal the influence of harvest season and tree age on the content of taxol and 10-DAB III, and provide the basis for the harvest time of Taxus madia.

METHODBranches and leaves of the labeled 25 three-year-old plants and 25 five-year-old plants were collected every two months from March 26,2009 to January 26, 2010. Taxol and 10-DAB III content of different age and growth season of Taxus in branches were determined by HPLC.

RESULTTaxol and 10-DAB III content were significantly different in different harvesting age. The content of five-year-old plants was significantly higher than that of three-year-old plants. Taxol and 10-DAB III contents were significantly different in different harvesting season, and the highest content of taxol and 10-DAB III was 0.56, 0.32 mg x g(-1), respectively, in May.

CONCLUSIONThe May is the suitable harvest season for T. madia, but the suitable harvest age need further study which according to the main active component and biomass accumulation.

Objective To discuss the clinical efficacy and safety of bilateral internal iliac artery Fogarty balloon occlusion in uterine curettage for patients with cesarean scar pregnancy(CSP).Methods The clinical data of a total of 80 CSP patients,who were admitted to the Fuyang People's Hospital of China between January 2021 and September 2022 to receive treatment,were retrospectively analyzed.The patients were divided into the observation group(n=40)and the control group(n=40).For the patients of the observation group,the hysteroscopic uterine curettage was carried out under the situation of bilateral internal iliac artery Fogarty balloon occlusion and during the operation the internal iliac artery was intermittently blocked.The embryo was removed,and the hemostasis was accomplished by electrocoagulation or surgical suture.For the patients of the control group,the hysteroscopic uterine curettage was performed within 1-2 days after uterine artery embolization(UAE).The digital subtraction angiography(DSA)fluoroscopy time,body surface radiation dose,blood loss during uterine curettage,time spent for uterine curettage,length of hospital stay,and postoperative follow-up results were compared between the two groups.Results Successful uterine curettage was accomplished and the uterus was retained in all the patients.In the observation group,no balloon-related complications occurred.In the control group,all the 40 patients developed different degrees of fever,pain at uterine area,and other post-embolization symptoms after UAE.In the observation group and the control group,the DSA fluoroscopy time was(9.2±1.1)seconds and(1 273.6±141.1)seconds respectively,the body surface radiation dose was(7.7±0.8)mGy and(1 503.8±101.8)mGy respectively,the differences between the two groups were statistically significant(both P＜0.05);the blood loss during uterine curettage was(30.3±14.7)mL and(27.5±13.2)mL respectively,the time spent for uterine curettage was(41.6±16.2)min and(42.8±15.0)min respectively,the differences between the two groups were not statistically significant(both P＞0.05);the length of hospital stay was(6.0±0.7)days and(7.3±0.8)days respectively,the difference between the two groups was statistically significant(P＜0.05).All patients were followed up for more than 3 months,the time of β-hCG turning to negative,time of vaginal bleeding,time of menstruation returning to normal,and patient satisfaction rate in the observation group were(21.1±2.4)days,(8.2±1.1)days,(29.5±2.2)days and 95.0%(38/40)respectively,which in the control group were(24.6±3.3)days,(13.6±2.6)days,(46.7±7.3)days and 67.5%(27/40)respectively,the differences in the above indexes between the two groups were statistically significant(all P＜0.05).Conclusion In performing uterine curettage for CSP patients,both bilateral internal iliac artery Fogarty balloon occlusion and UAE can significantly reduce the intraoperative blood loss,but bilateral internal iliac artery Fogarty balloon occlusion is superior to UAE in reducing radiation dose,in shortening the patient's hospital stay,the time of β-hCG turning to negative,the time of vaginal bleeding and the time of menstruation returning to normal,and in improving the patient satisfaction rate.

In recent years,the development and application of classical famous prescriptions have attracted much attention. However,the differences between ancient and modern conditions lead to difficulties in carrying out practical work. In this paper,with Houpu Wenzhong Decoction as an example,the key technologies of boiling granularity,water addition,boiling time and sample pretreatment methods were investigated on the basis of sufficient literature research. The experimental results showed that there was no significant difference in the concentration of index components between those with different granularity( 2 mm and 3-5 mm) and different decocting time( 30 min and 60 min),but the extraction rate of index components was relatively high when the granularity of powder was 2 mm and decocting time was 30 min. With the increase of water content,the concentration of index components and the extraction rate were increased in varying degrees. A certain proportion of methanol aqueous solution was used as the resolvent before content determination of the reference sample of Houpu Wenzhong Decoction,which could take into account both the spectral information of water-soluble components and fat-soluble components in the prescription,and help to display the overall information of the prescription' s chemical components more comprehensively. At the same time,the boiling and dispersing classical prescriptions in the Catalogue of Ancient Classical Prescriptions( the first batch) were collected and summarized in this study; the key influencing factors of decocting process were analyzed from different angles,and preliminary research suggestions were put forward,so as to provide a certain direction and reference for the establishment of quality standard of Houpu Wenzhong Decoction,as well as for the development,research and clinical application of boiling and dispersing classical prescriptions.
