ObjectiveTo establish a quality evaluation method for Zhuye Shigao granules(Zhuye Shigaotang) based on fingerprint and determination of index components, and to investigate the therapeutic effect of Zhuye Shigao granules on mice with cold-dampness pestilence attacking lung syndrome. MethodsThe fingerprint of Zhuye Shigao granules was established by high performance liquid chromatography(HPLC), and the methods for determination of total calcium, orientin, isoorientin, ginsenosides Rg1, Re and Rb1 and other 2 index components were established. Fifty ICR mice were randomly divided into the blank group, model group, Zhuye Shigao granules low, medium and high dose groups(9.3, 18.6, 37.2 g·kg-1·d-1), with 10 mice in each group. In addition to the blank group, the model mice with cold-dampness pestilence attacking lung syndrome was prepared by nasal drip of lipopolysaccharide combined with cold-dampness environment. Each administration group was given the corresponding liquid by gavage according to the dose, while the blank group and model group were given the same volume of normal saline by gavage. Then, the body temperature and organ index of mice in each group were measured, hematoxylin-eosin(HE) staining was used to investigate the lung tissue injury of mice in each group, and enzyme-linked immunosorbent assay(ELISA) was used to detect the changes of tumor necrosis factor-α(TNF-α), interleukin(IL)-lβ, IL-6, IL-10 levels in serum and lung tissue, as well as immunoglobulin(Ig)A and IgM levels in serum. ResultsThe fingerprint similarity of 10 batches of Zhuye Shigao granules was>0.950, and 20 common peaks were calibrated. Seven of them were identified, including peak 11(isoorientin), peak 12(orientin), peak 14(apioside liquiritin), peak 15(liquiritin), peak 17(apioside isoliquiritin), peak 19(isoliquiritin) and peak 20(liquiritigenin). The results of quantitative analysis showed that the content range of each index component in 10 batches of Zhuye Shigao granules was as follows:Total calcium of 9.978-11.294 mg·g-1, isoorientin of 0.033-0.041 mg·g-1, orientin of 0.046-0.055 mg·g-1, ginsenoside Rg1+ginsenoside Re of 0.748-0.762 mg·g-1, ginsenoside Rb1 of 0.151-0.197 mg·g-1, liquiritin of 1.106-1.366 mg·g-1, glycyrrhizic acid of 0.904-1.182 mg·g-1. Compared with the blank group, the body temperature of mice in the model group was significantly increased, the organ indexes of liver, lung and spleen were significantly decreased, the organ index of thymus was significantly increased, HE staining of lung tissue showed infiltration of inflammatory cells, a small amount of serous exudation was observed in the alveoli, and lung tissue was damaged. After the intervention of Zhuye Shigao granules, the pathological changes were improved compared with the model group. The expression levels of IL-1β, IL-6 and TNF-α were significantly increased, the expression level of IL-10 was significantly decreased in serum and lung tissue. The levels of IgA and IgM in serum were significantly decreased(P<0.01). Compared with the model group, the body temperature, the organ indexes and immune factor levels in serum and lung tissue of mice in the Zhuye Shigao granules medium and high dose groups were significantly reduced(P<0.05, P<0.01). ConclusionIn this study, the quality evaluation of Zhuye Shigao granules was carried out based on fingerprint combined with determination of index components, and the fingerprint of four herbs(Lophatheri Herba, Ophiopogonis Radix, Pinelliae Rhizoma and Glycyrrhizae Radix et Rhizoma) in this formula and the determination of 8 index components were established. The therapeutic effect of Zhuye Shigao granules on mice with cold-dampness pestilence attacking lung syndrome may be related to inhibiting inflammatory response and mediating immune regulation.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

To investigate the effects of sanguinarine (Sang) combined with cisplatin (Cis) in accelerating the apoptosis of bladder cancer EJ cells, CCK-8 method was used to detect the proliferation of bladder cancer EJ cells treated with different concentrations of Sang with the IC50 values calculated. Annexin V FITC/PI method was used to detect cell apoptosis in the control group, Sang group, Cis group and the combination group. Flow cytometer was used to detect cell cycle arrested. Western blot was used to detect the influence of Bcl-2 expression in the control group, Sang group, Cis group and the combination group. Nude mouse subcutaneous tumor model was constructed to verify that the combination group could accelerate the apoptosis of bladder cancer EJ cells and reduce the side-effects on mice. The safety of the Sang was evaluated by HE staining of vital organs in mice. In vitro, Sang could significantly inhibit the proliferation of EJ cells. Compared with the control group, the number of apoptosis EJ cells in the combination group was significantly increased (P < 0.05), and more cells were arrested in G2/M phase. The expression of Bcl-2 was significantly down-regulated in the combination group (P <0.001). In vivo, compared with the control group, the tumor growth was significantly slower, and a large number of apoptotic cells were inspected (P < 0.05) of the combination group. The side effects of cisplatin were reduced in the combination group. Sang has high biosafety and little side effect. Combined Sang and Cis can increase cell cycle G2/M block, down-regulate Bcl-2 expression, promote cell apoptosis and inhibit tumor growth.
