The present study employed UPLC-MS/MS to analyze and identify compounds in the raw powder of Tongluo Shenggu capsules. An HPLC method for the determination of vitexin content was established. The analysis of this drug was performed on a 30 ℃ thermostatic Acquity UPLC® BEH C18 (2.1 mm×100 mm,1.7 μm) column, with the mobile phase comprising 0.2% formic acid-methanol flowing at 0.3 mL /min in a gradient elution manner. Mass spectrometry was detected by ESI sources in both positive and negative ion modes for qualitative identification of chemical constituents. 12 flavonoid and 3 stilbenes compounds in the raw powder of Tongluo Shenggu capsules were successfully identified. Additionally, an HPLC method for the determination of vitexin content was established using a XBridge C18 column (4.6 mm × 250 mm, 5 µm) with a mobile phase of 0.05% glacial acetic acid in methanol for gradient elution, at a column temperature of 30 °C, a flow rate of 1.0 mL/min, and an injection volume of 20 μL. The method demonstrated good linearity in the concentration range of 10 µg/mL to 40 µg/mL (R=1.000) with an average recovery rate of 96.7%. The establishment of these methods provides a scientific basis for the quality control and development of the raw powder of Tongluo Shenggu capsules.

Objective:To evaluate the role of ferroptosis in reduction of intestinal ischemia-reperfusion injury (IRI) by sodium butyrate pretreatment in mice.Methods:Thirty SPF healthy male C57BL/6 mice, aged 6-8 weeks, weighing 20-23 g, were divided into 5 groups ( n=6 each) using a random number table method: sham operation group (S group), intestinal IRI group (IR group), intestinal IRI + sodium butyrate pretreatment group (IN group), intestinal IRI + sodium butyrate pretreatment+ FER-1 group (INF group), and intestinal IRI + sodium butyrate pretreatment + Erastin group (INE group). The intestinal IRI model was established by occluding the superior mesenteric artery for 45 min followed by reperfusion for 30 min in S group. In IN, INF and INE groups, sodium butyrate was administered by gavage at a dose of 500 mg/kg daily at 1 week before developing the model, while the equal volume of normal saline was given by gavage in the other two groups. The ferroptosis inhibitor FER-1 5 mg/kg and ferroptosis agonist Erastin 30 mg/kg were intraperitoneally injected at 1 h prior to ischemia in INF and INE groups. Mice were sacrificed after anesthesia at the end of reperfusion to obtain small intestinal tissues for examination of the pathological changes (using light microscopy) which were scored according to Chiu and for determination of the contents of Fe 2+, malondialdehyde (MDA), glutathione (GSH) and glutathione disulfide(GSSG) (by enzyme-linked immunosorbent assay), expression of glutathione peroxidase 4 (GPX4), solute carrier family 7 member 11 (SLC7A11), and ferritin heavy chain 1 (FTH1) (by Western blot). The ratio of GSH to GSSG was calculated. Results:Compared to S group, Chiu′s scores and contents of MDA and Fe 2+ were significantly increased, the expression of GSH, GPX4, FTH1 and SLC7A11 was down-regulated, and the GSH/GSSG ratio was decreased in IR group ( P<0.001). Compared to IR group, Chiu′s scores and contents of MDA and Fe 2+ were significantly decreased, the expression of GSH, GPX4, FTH1 and SLC7A11 was up-regulated, and the GSH/GSSG ratio was increased in IN and INF groups ( P<0.001). Compared to IN group, Chiu′s scores and contents of MDA and Fe 2+ were significantly increased, the expression of GSH, GPX4, FTH1 and SLC7A11 was down-regulated, and the GSH/GSSG ratio was decreased in INE group ( P<0.001). Conclusions:Ferroptosis is involved in sodium butyrate pretreatment-induced reduction of intestinal I/RI in mice.

In order to promote rational drug use in perioperative period, a perioperative clinical medication pathway system was constructed in the Affiliated Hospital of Qingdao University using the project management method of work breakdown structure (WBS). To establish this system, the following 7 tasks should be completed: requirement investigation of the pathway, formulation of drug usage standards, formulation of clinical medicine pathways, clinical communication and training, effect evaluation and supervision, informazation of medication supervision, and therapeutic drug monitoring, which were implemented by pharmacists of different specialties, respectively. After 4 years of effort, 6 general clinical medicine pathways were completed for antibiotics, analgesics, drugs in venous thromboembolism prophylaxis, nutritional support agents, airway management drugs, and proton pump inhibitors, respectively. These pathways had positive effects in improving the rational use of antibiotics, optimizing the postoperative pain management, and strengthening the risk assessment of thrombosis for patients in the surgical department. The personalized pathway constructed for the Cardiac Surgery Department and the multidimensional pharmaceutical intervention in the Anesthesiology Department also had remarkable effects. In conclusion, the construction of perioperative medication pathway system through WBS was helpful to refine the division of work tasks, reflect the value of pharmacists, and improve the quality of perioperative pharmaceutical services.

ObjectiveTo systematically evaluate the distribution of traditional Chinese medicine(TCM) syndromes of primary osteoporosis(POP) in China by using evidence-based medicine methods, and to understand the distribution law of the syndromes. MethodChina National Knowledge Infrastructure(CNKI), VIP Chinese Science and Technology Journal Database(VIP), WanFang Data Knowledge Service Platform(WanFang) and China Biology Medicine(CBM) were searched to obtain representative literature, and each database was searched from the 1994 World Health Organization defined diagnostic criteria for osteoporosis until May 1, 2023. Two researchers independently screened literature according to the criteria, extracted data, and cross-checked them. Meta analysis was conducted using R4.1.3, and subgroup analysis was performed. ResultA total of 56 Chinese papers were included, involving 14 415 patients. After standardized classification of syndromes, 11 articles were excluded, and Meta analysis results of the ultimately included 45 Chinese articles showed that the distribution frequencies of liver-kidney Yin deficiency syndrome, spleen-kidney Yang deficiency syndrome and kidney deficiency and blood stasis syndrome in 12 723 patients were 27%[95% confidence interval(CI) 0.24-0.31], 32%(95% CI 0.29-0.36), 36%(95% CI 0.30-0.42). Subgroup analysis showed that there was a statistically significant difference in the distribution of the three TCM syndromes in the north and south(P<0.05). In addition, the incidence of TCM syndrome fractures in different types of POP was 15%(95% CI 0.09-0.24) for liver-kidney Yin deficiency syndrome, 20%(95% CI 0.12-0.30) for spleen-kidney Yang deficiency syndrome, and 31%(95% CI 0.25-0.39) for kidney deficiency and blood stasis syndrome. ConclusionThe distribution of syndromes in POP patients is mainly kidney deficiency, accompanied by liver and spleen dysfunction. Liver-kidney Yin deficiency syndrome, spleen-kidney Yang deficiency syndrome and kidney deficiency and blood stasis syndrome are all the main syndromes of POP and osteoporotic fractures, and kidney deficiency and blood stasis syndrome is most closely related to the development of osteoporotic fractures. The reference standards for syndrome determination among the included studies are inconsistent, and in the future, it is necessary to focus on their determination standards to obtain consensus research results, at the same time, conduct large-scale syndrome research to obtain representative research results, providing a basis for clinical practice and research.
