Objective:To observe the effects of the Chinese medicine prescription Xiao-Cheng-Qi decoction (XCQD) on acute brain edema and inflammatory factors in rats with severe traumatic brain injury (sTBI).Methods:A total of 108 male Sprague-Dawley (SD) rats were divided into control group, sham operation group, sTBI model group, and XCQD low, medium, high dose groups by random number table method, with 18 rats in each group. sTBI rat model was prepared according to the modified Freeney method. At 6 hours after injury, the XCQD low, medium, and high dose groups were given XCQD 1.80, 2.78, and 4.59 g/kg by gavage, respectively, and the other three groups were given the same amount of normal saline, once a day for 3 days. After 3 days of injury, rats in each group were sacrificed after the modified neurologic severity score (mNSS) assessed. Pathological changes of brain tissue were observed under light microscope after hematoxylin eosin (HE) staining, water content of brain tissue was measured by dry-wet specific gravity method, and the expressions of aquaporin 4 (AQP4), tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in brain tissue were detected by Western blotting. Serum TNF-α and IL-1β levels were detected by enzyme linked immunosorbent assay (ELISA).Results:Compared with the normal group, the mNSS score of rats increased significantly, the structure of brain tissue was disordered, and pathological changes appeared such as inflammation, edema, pyknosis of nerve nuclei, water content, the protein expressions of AQP4, TNF-α and IL-1β in brain tissue, and the contents of TNF-α, IL-1β in serum were significantly increased. After XCQD intervention, the above indexes were significantly improved. Compared with sTBI model group, the mNSS score of XCQD medium and high dose groups significantly decreased (6.94±1.16, 6.88±1.02 vs. 8.61±1.09, both P < 0.05), and the pathological changes such as brain edema and inflammation were alleviated. Brain tissue water content, AQP4 protein expression and contents of serum TNF-α, IL-1β in XCQD low, medium, and high dose groups significantly decreased compared with sTBI model group [brain tissue water content: (78.25±0.71)%, (77.62±0.44)%, (76.70±0.74)% vs. (80.08±0.66)%; the expression of brain AQP4 protein (AQP4/β-actin): 0.86±0.13, 0.84±0.22, 0.65±0.13 vs. 1.08±0.14; serum TNF-α (ng/L): 106.34±15.07, 95.75±17.26, 89.00±17.36 vs. 141.96±29.47; serum IL-1β (ng/L): 90.41±12.88, 72.82±13.51, 71.32±16.79 vs. 128.57±22.56, respectively, all P < 0.05]. The protein expressions of TNF-α,IL-1β in brain tissue of XCQD medium and high dose groups also significantly decreased compared with sTBI model group [TNF-α (TNF-α/β-actin): 0.90±0.24, 0.79±0.35 vs. 1.17±0.15; IL-1β (IL-1β/β-actin): 0.91±0.21, 0.68±0.28 vs. 1.23±0.08, respectively, all P < 0.05]. Brain tissue water content, the expression of brain AQP4 protein, the levels of brain tissue and serum IL-1β in XCQD high dose group improved more significant than those of XCQD low dose group. Conclusions:XCQD can alleviate the acute brain edema in sTBI rats, and it is dose-dependent. The mechanism may be relevant to reduce the secondary inflammatory response of sTBI by inhibiting the expression of inflammatory factors TNF-α and IL-1β.

OBJECTIVE： To provide reference for improving emergency capacity of the hospital pharmacy department in response to the novel coronavirus pneumonia （COVID-19） epidemic. METHODS ：According to the related regulations and requirements of Law of the People ’s Republic of China on the Prevention and Control of Infectious Diseases ，combined with the situation of COVID- 19 epidemic prevention and control ，and management experience of relevant hospitals ，on the basis of in-depth analysis of drug supply and quality assurance ，drug dispensing management ，provision of clinical pharmaceutical services and other related material support of hospital pharmacy department，integrated emergency management model was constructed for COVID- 19 epidemic prevention and control ，and the precautions and response measures of each link were sorted out. RESULTS ：Integruted emergency management mode for COVID-19 epidemic prevention and control in hospital pharmacy department included but was not limited to human resource management，drug and disinfection products supply management （mainly including key treatment drugs and disinfection product list formulation，control，inventory increase ，etc.）；drug dispensing management （mainly including prescription ，pharmacy window ， planning quantitative reserve ， drug return ， etc.）；clinical pharmaceutical care management （mainly including providing pharmaceutical information support ，online pharmaceutical service ，monitoring drug safety ，etc.）；personnel protection and disinfection （mainly including personnel protection ，environment and window ，equipment and container ，paper prescription disinfection，etc.）；special management of donated drugs ；prevention and control knowledge training ；pharmaceutical education and scientific research management ，etc. CONCLUSIONS ：The integrated emergency management model for epidemic prevention and control is helpful for hospital pharmacy to manage public health emergencies. During the outbreak of COVID- 19，hospital pharmacy department should start integrated emergency management mode for epidemic prevention and control ，strengthen the risk control of each link ，and play a good role in the key functional departments in the special period.
