Bacterial endotoxin test of (R)-lansoprazole raw material XU Meibao, PEI Yusheng, CHEN Chen, LI Wenlong, LIU Tao, CAI Tong 2024, 21(8): 852-856.  DOI: 10.19803/j.1672-8629.20240375 Abstract ( 98 )   PDF (1339KB) ( 111 )   Objective To establish a bacterial endotoxin detection method for the poorly soluble active pharmaceutical ingredient (R)-Lansoprazole. Methods Three methods were attempted to establish the bacterial endotoxin detection method.① The test sample was dissolved in acetonitrile to a concentration of 10 mg·mL-1, diluted 100-fold, and tested using the gel-clot method with a lysate sensitivity of 0.25 EU·mL-1. ② The sample was dissolved in 1.4 mg·mL-1 sodium hydroxide solution to a concentration of 10 mg·mL-1, diluted 600-fold, and tested for bacterial endotoxins using the gel-clot method with a lysate sensitivity of 0.03 EU·mL-1.③ Dissolve the test sample in chloroform, and then perform endotoxin detection using extraction method. Results For all three batches of test samples, dissolving the samples in both acetonitrile and 1.4 mg·mL-1 sodium hydroxide solution then diluted by water for bacterial endotoxin test, could eliminate the interference of the solvent and test sample on endotoxin detection. The results of the interference test meet the requirements. The endotoxin content of the test samples was found to be below the limit and in compliance with the pharmacopoeia requirements. However, the chloroform extraction method has significant interference and the results are not valid. Conclusion A bacterial endotoxin detection method for the active pharmaceutical ingredient (R)-Lansoprazole is successfully established, which solves the detection problem of this sample and provides a reference for establishing bacterial endotoxin detection methods for other insoluble samples.

Anti-fatigue effects and mechanism of ginseng combined with caffeine in rats ZHENG Haiyun, ZHANG Wen, WANG Shaonan, ZHAO Haiyu, DU Shouying 2024, 21(8): 863-870.  DOI: 10.19803/j.1672-8629.20240244 Abstract ( 140 )   PDF (1876KB) ( 137 )   Objective To evaluate the anti-fatigue effect and mechanism of ginseng extract combined with caffeine in rats. Methods The two components combination index was used to evaluate the synergistic effect of ginseng and caffeine in combating fatigue. SD rats were randomly divided into the control group, model group, ginseng group (60 mg·kg-1), caffeine group (3 mg·kg-1), and combined group (30 mg·kg-1+1.5 mg·kg-1). A rat fatigue model was established via weight bearing swimming, and the drugs were administered once daily for 21 consecutive days. The anti-fatigue effect was evaluated by weight bearing swimming experiments. Colorimetry was used to detect the levels of urea nitrogen (BUN), lactic acid (LD), and liver/skeletal muscle glycogen in each group of rats. Enzyme linked immunosorbent assay (ELISA) was adopted to detect the levels of interleukin 6 (IL-6), interleukin 1β (IL-1β), and C-reactive protein (CRP) while network pharmacology was used to explore the possible mechanism of anti-fatigue effect of ginseng extract combined with caffeine. Results The TCCI of ginseng and caffeine was calculated to be 0.17~0.61, indicating a synergistic anti-fatigue effect. Compared with the model group, each drug administration group prolonged the weight bearing swimming time of rats to varying degrees, increased the content of glycogen in liver/skeletal muscle tissues, decreased the level of BUN in serum, and reduced the level of inflammatory cytokines. Network pharmacology analysis found that the anti-fatigue effects were exerted through such pathways as PI3K-Akt and MAPK signaling pathway. Conclusion Ginseng extract combined with caffeine could significantly decrease the accumulation of metabolic products such as lactic acid, reduce the breakdown of glycogen, and improve fatigue symptoms of model rats.

Methods The target proteins and signaling pathways were retrieved from PharmMapper, TCMSP, STRING, GeneCards, OMIM and DAVID database. The potential targets of roxadustat combined with Danggui Buxue Tang in treating RA were explored. A “drug-target-pathway” model was established to predict possible biological pathways. Subsequently, rat experiments were conducted to validate the main targets. Results Network pharmacology research found that the combination of roxadustat and Danggui Buxue Tang mainly exerted therapeutic effects on renal anemia through four common protein targets, namely NR3C2, AR, NR1I3, and RUNX1T1, as well as through 16 common signaling pathways such as PI3K-Akt pathway. The combination of roxadustat and Danggui Buxue Tang could upregulate the expression of target protein AR but inhibit the expression of target protein NR3C2 to exert its effects. Conclusion The combination of roxadustat and Danggui Buxue Tang can improve inflammation and oxidative stress in the body by inhibiting the expression of NR3C2 and upregulating the expression of AR, thereby exerting a therapeutic effect on renal anemia.

Methods One hundred and sixty normal rats were randomly divided into four groups: the negative control group (pure water) and three-dosage groups of Zhinao capsules (6 400, 2 100 and 710 mg·kg-1), with 40 rats in each. The rats were orally administrated with Zhinao capsules for 26 weeks. The health status, food consumption and body weight of rats were observed during the test. At 13 weeks, 26 weeks and after two weeks of recovery, 10, 20 and 10 rats in each group were dissected respectively before hematology, blood biochemistry, the organ-body ratio and histopathology were measured. Results Compared with the negative control group, the body weight of male rats in the high-dose group decreased from week 13 to week 21 (P < 0.05) but returned to normal at 26 weeks (P > 0.05). Compared with the negative control group, some hematological and blood biochemical indexes of rats in the medium and high dose groups were increased before they decreased (P < 0.05), but all were within the normal range. Compared with the negative control group, the male kidney/body ratio, the female liver/body ratio and the ovary/body ratio were increased in the high dose group after 26 weeks of administration (P < 0.05). There was no difference in the organ-body ratio between the three groups in the two weeks of recovery (P > 0.05), and no histopathological lesions of organs induced by drugs were observed either. Conclusion Long-term administration of Zhinao capsules is highly safety, and the NOAEL of Zhinao capsules is considered to be 6 400 mg·kg-1, equal to 95 times the proposed clinical adult .

Methods A retrospective study was conducted on a patient with cerebral infarction who developed a generalized rash after polypharmacy (amlodipine, aspirin, atorvastatin, urinary kallidinogenase and edaravone dexborneol) was conducted. The rash worsened even after discontinuing urinary kallidinogenase and edaravone dexborneol and switching aspirin to clopidogrel. The rash subsided only after discontinuing all medications except for antiallergic drugs. When clopidogrel and amlodipine were reintroduced, the rash did not recur. The Naranjo score and literature review were used to analyze the potential allergenic drug. Results Based on the clinical presentation of the rash and its relationship with the timing of medication, combined with the Naranjo score of 5 for atorvastatin, it is very likely that atorvastatin is the drug causing the patient’s rash. Conclusions Clinicians should be aware that atorvastatin can cause severe generalized rash in chronic diseases patients a few days after administration during polypharmacy.

One case of ureterolith combined with gallstone caused by Ceftriaxone sodium for injection in children CHAO Ying, ZHANG Xuemei, ZHANG Chengjian, WANG Bei 2024, 21(8): 943-945.  DOI: 10.19803/j.1672-8629.20240158 Abstract ( 120 )   PDF (1140KB) ( 130 )   Objective To explore the mechanism of ceftriaxone injection causing ureterolith and gallstone in children, and provide reference for the safe and reasonable use of ceftriaxone injection in clinical practice. Methods The diagnosis and treatment process of ureterolith and gallstone in the children after receiving treatment with ceftriaxone was analyzed. And Related literature were searched to analyze the mechanism of adverse drug reactions and clinical countermeasures. Results After 5 days of using ceftriaxone, this child developed ureterolith and gallstones. After discontinuing the use of ceftriaxone, ureterolith naturally improved. Based on the analysis of relevant literature, children may develop ureterolith and gallstone after using ceftriaxone, but most of them disappear automatically after discontinuation. Conclusion Ceftriaxone is likely to cause ureterolith and gallstone in children, which deserves more attention in clinic. References | Related Articles | Metrics

Methods of preparation of Bupleuri Radix based on the idea of ‘Tong Quan Da Bian’ ZHENG Changhui, MA Lina, HE Ting, ZHAO Wei, GU Yuanyuan, HU Xiaozhen, NIU Yuanfei, GUO Yueshan, CAO Junling 2024, 21(8): 955-960.  DOI: 10.19803/j.1672-8629.20240192 Abstract ( 84 )   PDF (1380KB) ( 127 )   Objective To analyze the ancient and modern experience concerning medications with Bupleuri Radix and recent research progress in processed products of this drug based on the idea of “Tong Quan Da Bian” so as to provide reference for the study of the processing mechanism and processing technology of Bupleuri Radix. Methods The evolution of processing methods of Bupleuri Radix and the way in which Bupleuri Radix decoction pieces were used clinically were retrieved from such databases as Chinese Medical Classics and Duxiu. Based on literature review, the current research progress in a range of processed products of Bupleurum chinense was analyzed. Results According to the records of medical classics, the processed products of Bupleuri Radix were diverse, and there were considerable differences in the efficacy of different processed products: the effect of soothing the liver and relieving depression by vinegar Bupleuri Radix was enhanced while the property of elevating and dispersing qi was weakened; the effect of nourishing yin and reducing fever by Bupleuri Radix processed with trionyx blood was enhanced, and the property of floating yang was weakened; the effect of relieving rigidity of muscle, activating collaterals and pain relief was enhanced. Modern research has interpreted the connotations of different processed products of Bupleuri Radix to different extents, but there are still some problems, such as variations in processing technology and inconsistent quality standards. Conclusion Bupleuri Radix has been long used as a medicinal herb, with wide clinical applications and varieties of processed of products. It is urgent to conduct systematic research on the pharmacodynamic material basis and processing mechanism of different processed products, advance our understanding of the connotations of different processed products of Bupleuri Radix, standardize the processing technology and formulate better quality standards, provide processed products of Bupleuri Radix that are stable and controllable in quality and of different varieties for clinical use, and give full play to the clinical superiorities of Bupleuri Radix.
