OBJECTIVE To explore the effects and potential mechanism of evodiamine on inflammatory response and apoptosis of epithelial cells in asthma model rats. METHODS SD rats were separated into control group， model group， evodiamine low-dose group （10 mg/kg）， evodiamine high-dose group （20 mg/kg）， dexamethasone group （positive control， 0.5 mg/kg）， epidermal growth factor （EGF） group [mitogen-activated protein kinase （MAPK） activator， 10 μg]， evodiamine high-dose+EGF group （20 mg/kg evodiamine+10 μg EGF）， with 10 rats in each group. Except for the control group， the other groups were sensitized by 3-point injection of 10% ovalbumin（OVA）-aluminium hydroxide mixture and stimulated by inhalation of 2%OVA nebulized liquid to establish an asthma model. The count of inflammatory cells （macrophages and lymphocytes） in bronchoalveolar lavage fluid （BALF） was detected in each group； pathological changes of lung tissue in rats were observed； the apoptosis of airway epithelial cells， the levels of serum inflammatory factors [tumor necrosis factor-α， interleukin-6 （IL-6） and IL-4]， the expressions of pathway-related proteins p38 MAPK， phosphorylated p38 MAPK （p-p38 MAPK）， signal transduction and transcription activating factor 1 （STAT1）] and apoptosis-related proteins [B cell lymphoma-2 （Bcl-2） and Bcl-2 associated X protein （Bax）] were all detected in lung tissue. RESULTS Compared with the control group， bronchial mucosal edema， thickening of alveolar septa and extensive infiltration of inflammatory cells were observed in the lung tissue of rats in the model group； the number of inflammatory cells， apoptosis rate of airway epithelial cells， the levels of inflammatory factors， p-38 MAPK/p-38 MAPK， and the protein expressions of Bax and STAT1 were increased significantly； the expressions of Bcl-2 protein and Bcl-2/Bax were reduced significantly （P＜0.05）. Compared with the model group， the pathological changes in lung tissues were alleviated to varying degrees in evodiamine low-dose and high-dose groups， and dexamethasone groups， and the above indicators were significantly reversed. However， the change trends of corresponding indicators in the EGF group were opposite to the above （P＜0.05）. EGF could significantly attenuate the effect of high-dose evodiamine on inflammatory response in asthmatic rats （P＜0.05）. CONCLUSIONS Evodiamine can relieve inflammatory reactions and inhibit the apoptosis of airway epithelial cells in asthmatic rats， the mechanism of which may be associated with inhibiting p38 MAPK/STAT1 signaling pathway.

OBJECTIVE To explore the risk signals of Fluocinolone acetonide intravitreal implants and promote safe and rational drug use for patients. METHODS Based on the data from the Hainan Province Franchised Drug Adverse Reaction Monitoring Subsystem （hereinafter referred to as the “Franchised Drug Monitoring System”） and the FDA Adverse Event Reporting System （FAERS）， the adverse drug reaction （ADR）/adverse drug event （ADE） reports of Fluocinolone acetonide intravitreal implants were coded by using system organ classification and preferred terminology， and relevant patient information was collected. Risk signal mining was carried out by using the reporting odds ratio （ROR） method and the comprehensive standards method of the UK Medicines and Healthcare Products Regulatory Agency （hereinafter referred to as the “MHRA method”）. RESULTS Among the 72 reports of Fluocinolone acetonide intravitreal implants received by the Franchised Drug Monitoring System， the ratio of male to female was 1∶1.4， the patient’s age was mainly distributed between 18 and 64 years old； ADR/ADE affected 5 systemic organs， with eye organ diseases accounting for 87.7%； among them， there were 9 new and general ADR reports （12.5%） and 4 severe ADR reports （5.6%）； ROR method and MHRA method both identified three risk signals： cataracts， glaucoma， and high intraocular pressure. Among the 244 reports received by the FAERS database， the ratio of male to female was 1∶1.5； ADR/ADE damage affected 10 systemic organs， with 46.1% suffering from various injuries， poisoning， and operational complications， and 32.0% suffering from product problems； there were 20 severe ADR reports （8.2%）； ROR method and MHRA method both identified 19 risk signals， including implantation complications， medication system issues， etc. CONCLUSIONS When using Fluocinolone acetonide intravitreal implants in clinical practice， in addition to paying attention to eye ADR/ADE such as high intraocular pressure， cataracts， and glaucoma， attention should also be paid to the potential risks caused by ADE due to product quality and unreasonable use.

Breast cancer has become one of the most prevalent cancers among women worldwide,posing a significant burden on their health.Current standard therapies are often expensive and associated with the risk of drug resistance.Drug repurposing has gained increasing attention as a cost-effective and time-saving strategy in pharmaceutical research.Many drugs already in clinical use or undergoing clinical trials can be repurposed for the treatment of new clinical indications.Based on a comprehensive understanding of the mechanisms of action of these drugs and the pathophysiological processes of breast cancer,researchers can better identify drugs with potential anti-breast cancer properties and translate them into clinical practice.This paper provides a review of the current research on repurposing existing drugs for breast cancer treatment,summarizes the mechanisms of action of these drugs,and discusses the challenges associated with the strategy of drug repurposing.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective To analyze the application dose of ciprofol combined with fentanyl in patients undergoing gastroscopy.Method 99 gastroscopy patients from June 2021 to June 2023 were selected as the study objects,and divided into three groups with 33 cases each by random number table method.Group A was given 0.3 mg/kg ciprofol+1.5 μg/kg fentanyl anesthesia,group B was given 0.4 mg/kg ciprofol+1.5 μg/kg fentanyl anesthesia,group C was given 0.5 mg/kg ciprofol+1.5 μg/kg fentanyl anesthesia.Anesthesia,examination,electroencephalogram bispectral index(BIS),mean arterial pressure(MAP),heart rate(HR)and adverse reaction were compared among all groups.Results The success rate of the first anesthesia in Group A was lower than that in Group B and Group C,the gastroscopy examination time was longer than that in Group B and Group C,and the awakening time and hospital leave time were shorter than those in Group B and Group C,the awakening time and hospitalization time of Group B were shorter than those of Group C,the BIS of Group A at time points T2 to T5 was higher than that of Group B and Group C,the MAP and HR levels at time points T2 to T5 in Group A were lower than those in Group B and Group C,the incidence of body movement and coughing in Group A was higher than that in Group B and Group C,the incidence of hypotension and nausea and vomiting in Group C was higher than that in Group A and Group B,and the differences were statistically significant(P<0.05).One patient in Group A and one patient in Group C stopped gastroscopy due to hypoxemia,Group B did not experience hypoxemia,and the difference was not statistically significant(P>0.05).There were 4 cases in Group A,6 cases in Group B and 10 cases in Group C who received intervention with vasoactive drugs due to hypotension,and the difference was statistically significant(P<0.05).Conclusion Patients undergoing gastroscopy which should use 0.4 mg/kg ciprofol+1.5 μg/kg fentanyl anesthesia can achieve better anesthesia effect,shorten examination time and hospitalization time,stabilize vital signs,and reduce adverse reaction incidence rate.
