This experiment aims to study the taste-masking effects of different kinds of corrigent used individually and in combination on ibuprofen oral solution, in order to optimize the taste-masking formulation. Firstly, a wide range of corrigent and the mass fractions were extensively screened using electronic tongue technology. Subsequently, a combination of sensory evaluation, analytic hierarchy process (AHP)-fuzzy mathematics evaluation, and Box-Behnken experimental design were employed to comprehensively assess the taste-masking effects of different combinations of corrigent on ibuprofen oral solution, optimize the taste-masking formulation, and validate the results. The study received ethical approval from the Review Committee of the Beijing University of Chinese Medicine (ethical code: 2024BZYLL0102). The results showed that corrigent fractions and types were screened separately through single-factor experiments. Subsequently, a Box-Behnken response surface design combined with AHP and fuzzy mathematics evaluation was used to fit a functional model:

"Solid-liquid excipients" co-production is one of the typical processing methods of excipients used from ancient times to the present day, and is widely applied in various processing schools and regional specialty varieties. This method significantly reduces the toxicity of traditional Chinese medicine(TCM), moderates medicinal properties, and enhances clinical efficacy. However, modern scientific research has given it limited attention, and many co-production methods of "solid-liquid excipients" have not been applied in production and practice. This paper reviewed the historical development of "solid-liquid excipients" co-production, outlined modern processing standards and methods in different processing schools, and further elaborated on the purposes and effects of this co-production method. This study is expected to provide references and evidence for further in-depth research, inheritance, innovation, and practical application.

Objective To explore the short-term and medium-term efficacy of modified loop plate suspension fixation in the treatment of acromioclavicular joint dislocation.Methods A retrospective analysis was performed in 72 patients with acromioclavicular joint dislocation and treated in Yangzhou Hospital of Traditional Chinese Medicine from December 2020 to December 2022.The patients were divided into modified group(n=37)and traditional group(n=35)according to different surgical methods.The modified group was treated with modified loop plate suspension fixation,and the traditional group was treated with clavicular hook plate fixation.The perioperative indexes,Constant-Murley score,and shoulder joint mobility and pain visual analogue scale(VAS)score before operation,3 months and 6 months after operation,postoperative complications rates,excellent and good rate of shoulder joint function recovery at 6 months after operation were compared between the two groups.Results The incision length and recovery time in the modified group were significantly shorter than those in the traditional group(P<0.001),and the intraoperative blood loss was significantly less than that in the traditional group(P<0.001).The Constant-Murley score,shoulder flexion and abduction activity in both groups at 3 months and 6 months after operation were significantly higher than before operation(P<0.05),and these improvements were greater in the modified group(P<0.05).The VAS scores of the two groups at 3 months and 6 months after operation were significantly lower than before operation(P<0.05),and these decreases were greater in the improved group(P<0.05).There were no significant differences in the excellent and good rate of shoulder joint function recovery and the incidence of postoperative complications between the two groups.Conclusions The modified titanium loop plate suspension fixation in the treatment of acromioclavicular joint dislocation can reduce surgical trauma and postoperative pain,and promote the recovery of shoulder joint function.

The quality difference of pharmaceutical excipients from different sources affects the molding properties of the powder, resulting in changes in the properties of the final product. In this study, the critical quality attributes of hydroxypropyl methylcellulose (HPMC) with different specifications from two manufacturers (manufacturer A and manufacturer B) were characterized including particle size, physical morphology, viscosity and powder physical quality attributes. Aminophylline, diclofenac sodium, and metformin hydrochloride were utilized as model drugs with different solubility to prepare sustained-release tablets, and the effect of HPMC from different sources on drug release of sustained-release tablets

A total of 15 batches of the substance reference of Guizhi Jia Gegen Decoction(GZGGD) were prepared and the characteristic fingerprints of them were established. Furthermore, the similarity of the fingerprints and peak attributes were explored. The extraction rate, and the content and the transfer rate ranges of the index components, puerarin, paeoniflorin, liquiritin, and ammonium glycyrrhizate were determined for the analysis of the quality value transfer. The result demonstrated that the fingerprints of the 15 batches of the samples showed high similarity(>0.99). A total of 15 characteristic peaks were identified from the fingerprints, with 10 for Puerariae Lobatae Radix, 1 for Cinnamomi Ramulus, 2 for Paeoniae Radix Alba, and 2 for Glycyrrhizae Radix et Rhizoma. The content of puerarin was 11.05-18.35 mg·g~(-1) and the average transfer rate was 21.27%-39.49%. The corresponding figures were 7.95-10.90 mg·g~(-1) and 23.28%-43.23% for paeoniflorin, 3.25-4.95 mg·g~(-1) and 32.31%-61.27% for ammonium glycyrrhizate, and 3.65-5.80 mg·g~(-1) and 14.57%-27.05% for liquiritin. The extraction rate of the 15 batches of samples was in the range of 16.85%-21.78%. In this paper, the quality value transfer of the substance reference of GZGGD was analyzed based on characteristic fingerprint, content of index components, and the extraction rate. This study is expected to lay a basis for the quality control and further development of GZGGD.
