This paper was aimed to establish a new method for evaluating the anaphylactoid reaction of 15 batches of Zushima Injection from different manufacturers in vitro. Basophilic leukemia cell line RBL-2 H3 cells were cultured in vitro and Compound 48/80 was selected as positive drug. Real-time cell analysis(RTCA) system was used to detect the changes of cell index(CI) value after drug intervention. The degranulation of RBL-2 H3 cells was verified with the toluidine blue staining technology by observing the changes of cell morphology and skeleton. Clustering method was used to analyze the CI values of 15 batches of Zushima Injection on RBL-2 H3 cells. The results showed Compound 48/80(20 μg·mL~(-1)) significantly changed the cell morphology and cytoskeleton, with obvious degranulation. After adding Compound 48/80, CI value decreased rapidly within 30 minutes, then decreased slowly, suggesting that RTCA system can be used for rapid and sensitive evaluation of RBL-2 H3 cell degranulation. The results of cluster analysis showed that Zushima Injection from different manufacturers had different effects on RBL-2 H3 cells. S1-S8 and Compound 48/80 groups were grouped into one cluster, which suggesting that the sample might have potential clinical anaphylaxis. S9-S15 and the normal control group were grouped into one cluster, suggesting there was no anaphylactoid reaction in the sample. In this study, a rapid in vitro anaphylaxis evaluation technique based on RTCA system and pattern recognition method was established, which can be used for rapid in vitro evaluation of anaphylaxis for traditional Chinese medicine injection.

Objective To investigate the effect of acupuncture and moxibustion plus Zushima on serum vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (b FGF) in patients with knee osteoarthritis.Method Two hundred and thirty-six patients with knee osteoarthritis were allocated, using a random number table, to two groups, 118 cases each. The control group was treated with Celecoxib and the observation group, with acupuncture and moxibustion plus Zushima. The therapeutic effects, and pre-treatment and post-treatment VAS scores and WOMAC scores and serum VEGF and bFGF levels were compared between the two groups of patients. The adverse reaction incidences were compared between the two groups of patients. Result The total efficacy rate was 87.3％ in the control group and 94.9％ in the observation group and was significantly higher in the observation group than in the control group (P<0.05). There were no statistically significant pre-treatment differences in the VAS score and WOMAC score between the two groups (P>0.05). The VAS score and WOMAC score decreased significantly in both groups after treatment (P<0.05). After treatment, there was no statistically significant difference in the VAS score between the two groups (P>0.05) but the WOMAC score was significantly lower in the observation group than in the control group (P<0.05). There were no statistically significant pre-treatment differences in VEGF and bFGF between the two groups (P>0.05). After treatment, VEGF and bFGF decreased significantly in both groups (P<0.05) and were significantly lower in the observation group than in the control group (P<0.05). The adverse reaction incidence was3.4％ in the control group and 1.7％ in the observation group with no statistically significant difference between the two groups (P> 0.05). Conclusion Acupuncture and moxibustion plus Zushima can reduce inflammatory reactions, inhibit synovial angiogenesis, and effectively relive the pain, and improve articular functions in the treatment of knee osteoarthritis.

Objective To explore the changed trend of endogenous lipid metabolites in rats with rheumatoid arthritis during different disease periods and the regulation of Zushima Tablets on differential metabolites based on UPLC-Q-Exactive Orbitrap MS. Methods The collagen-induced arthritis (CIA) rats were established using bovine type II collagen. The serum samples were collected before (0 d) and 14, 21, and 36 d after model construction from control, model, and Zushima Tablets groups [0.6 g/(kg•d)], respectively. The lipids were extracted and identified by bioinformatics analysis to find the lipid differential metabolites. Results It was obviously observed that lipid metabolism disordered in CIA rats compared with the control group. The content of three acylcarnitines was increased significantly while the level of TG showed a downward trend in the CIA model group when the TG carbon chain was shorter than 58 carbon atoms. To the opposite, the content of TG substances with atomic number greater than fifty-eight in the model group was significantly higher than that of the control group. Zushima tablet obviously regulated the metabolism levels of a phosphatidylserine, a ceramide, two acylcarnitines, four phosphatidylcholines, and four triglycerides. Conclusion This study demonstrated that rheumatoid arthritis caused the disorder of lipid metabolism while Zushima Tablets had regulatory effects on some lipid metabolites.

Objective: To observe the regulating action of Zushima Gancao Tablet on abnormal metabolites by analyzing the changes of endogenous metabolites in plasma of rheumatoid arthritis (RA) rats, and to explore the mechanism of Zushima Gancao Tablet in treating RA from the perspective of metabonomics. Methods: Rats were divided into normal group (NG), model group (MG), positive medicine group (PMG), and Zushima Gancao Tablet group (ZGG). Adjuvant arthritis (AA) rats were established with freund complete adjuvant, rats in PMG and ZGG groups were ig administered with tripterygium glycosides and Zushima Gancao Tablet respectively for a month. Plasma samples were collected on days 1, 10, 20, and 28 before and after administration. UPLC/LTQ-Orbitrap-MS was applied to analyzing the metabolic profile changes of each group in different durations of the disease and mechanism of drug intervention. Results: The related pathways of AA mainly involved metabolisms of amino acids, lipids, nucleic acids, and vitamins. Zushima Gancao Tablet had great effect on AA by regulating 12 biomarkers. Conclusion: Small molecule metabolites in AA rats are deviated from the normal ones. The effects of Zushima Gancao Tablet and positive medicine (tripterygium polyglycoside) on AA are similar, but the mechanisms were different. Zushima Gancao Tablet down-regulates the level of LPC in secondary lesions while tripterygium polyglycoside tablets could effectively inhibit the metabolisms of a variety of amino acids during acute inflammation.
