Objective To establish a method for the separation and purification of total saponins from Radix Clematidis by column chromatography of macroporous absorptive resin. Methods Radix clematidis was extracted with 70 % ethanol and then the extraction was purified with D101 macroporous absorptive resin. After eluting with distilled water and 30 % , 50 % and 70 % ethanol, absorption capability and elution parameters of macroporous absorptive resin were measured by the indexes of elution rate and refinement rate of total saponins. Results Total saponins of Radix Clematidis were enriched in the 50 % ethanol eluted solution fraction. The elution rate of macroporous absorptive resin was 71.26 % and absorption capability was 53.36 mg/g . Conclusion It is feasible to use macroporous absorptive resin for the isolation and purification of total saponins from Radix Clematidis. The optimum elution condition is: removing water- soluble impurity by water, eluting total saponins with 50 % ethanol.

OBJECTIVE To establish a working model for the cough and asthma pharmaceutical care clinic and analyze the effects of outpatient pharmaceutical care interventions on patients. METHODS A pharmaceutical care clinic for cough and asthma was established in our hospital， with comprehensive regulations and rules， complete infrastructure and defined pharmaceutical care workflows. The demographic data of patients （gender， age， residence， disease duration and so on） were collected from May 2021 to December 2024. Indicators including health status， disease severity， inhalation technique， and medication adherence during visits and follow-up were collected and analyzed statistically， to assess the effects of pharmaceutical care interventions on patients. RESULTS The service procedure for the cough and asthma pharmaceutical care clinic in our hospital was established. A total of 215 patients’ basic information was collected. It was found that among the patients， males accounted for 55.35%， with an average age of （60.91±15.75） years old. Patients aged 60 to 69 constituted the largest proportion at 28.37%， and they exhibited relatively poor medication adherence [with an average score of （5.64±1.76）]. The majority of patients were diagnosed with chronic obstructive pulmonary disease （COPD） and prescribed budesonide/formoterol powder inhalers. In 68 follow-up cases， EQ-5D-5L scores increased by 5.81 points （P＜0.05）； COPD Assessment Test （CAT） scores decreased by 4.05 points （P＜0.05）， indicating reduced disease burden. Asthma Control Test （ACT） scores improved by 4.80 points， reaching partial control levels. Inhaler technique scores increased by 2.31 points （P＜0.05）. Medication adherence scores rose by 1.09 points （P＜0.05）. Patient satisfaction was over 90%. CONCLUSIONS After pharmaceutical care intervention， patients’ health status， disease severity， inhalant use technique， and compliance have all improved， and their satisfaction with the cough and asthma pharmaceutical care outpatient service is high. The pharmaceutical care intervention provided by the cough and asthma pharmaceutical care outpatient service can improve patients’ disease symptoms and medication compliance， and enhance the level of safe and rational drug use in the hospital.
