Objective To analyze the characteristics of adverse drug reactions （ADR） reported in Sixth People’s Hospital South Campus, Shanghai Jiaotong University from 2021 to 2023, to provide reference for promoting rational clinical drug use. Methods ADR data reported in our hospital were collected retrospectively, including patients’ basic information, drugs causing adverse reactions, types of adverse reactions and outcomes. Descriptive analysis methods were used to summarize and analyze the data. Results A total of 979 cases of ADR were reported in our hospital from 2021 to 2023. The highest proportion of patients with ADR occurred in the age range of 31 to 50, and more male patients （63.5%）. The top five drugs involved with adverse reactions were antibiotics （48.8%）, Chinese medicine injections（19.2%）, vitamins（7.5%）, Chinese traditional medicine（7.2%）, equine tetanus immunoglobulin（6.3%）. Among antibiotics, cefuroxime, ceftazidime and cefotiam were the majority. The organs/systems involved in all ADR were mainly skin and accessories damage （55.4%）. The clinical manifestations were rash, itching, and maculopapular rash. Conclusion From 2021 to 2023, the most common drugs causing adverse drug reactions in our hospital were mainly antibacterial drugs, and the rational clinical use of antibacterial drugs still needs to be concerned.

Objective:To explore whether thiotert treatment can inhibit proliferation and induce apoptosis in myelodysplastic syndromes(MDS)cells.Methods:CCK-8 assay was used for determining the cytotoxicity of thiotert to MDS cell line SKM-1 and the reversal effect of GSH,NAC,and Z-VAD-FMK on thiotert-induced inhibition of cell viability.EdU assay was deployed to detect the cell proliferation ability.Intracellular reactive oxygen species(ROS)was measured by flow cytometry after DCFH-DA staining.The expression of DNA damage-and apoptosis-related proteins was detected by Western blot.Results:Thiotert treatment significantly suppressed the cell viability and proliferation ability in SKM-1 cells.A large amount of ROS generation and markedly elevated C-PARP,C-Caspase 3,and γ-H2AX were observed after thiotert administration,while BCL-2 was significantly decreased.In addition,GSH,NAC,and Z-VAD-FMK were able to mitigate the cytotoxicity of thiotert on SKM-1 cells.Conclusion:Thiotert can promote MDS cell apoptosis by mediating ROS production and pro-apoptotic proteins expression.

Diabetic kidney disease(DKD)is one of the most important complications of diabetes.In recent years,domestic and foreign studies have found that mammalian target protein of rapamycin(mTOR)related signaling pathway is a classic pathway involved in the regulation of autophagy,which can achieve the therapeutic effect of DKD by targeting the autophagy pathway,and plays a crucial role in the prevention and treatment of DKD.In this paper,we reviewed the mechanism of mTOR-related signaling pathway targeted autophagy in the prevention and treatment of DKD,in order to provide a new reference and basis for clinical prevention and treatment of DKD.

On May 27,2021,the U.S.Food and Drug Administration(FDA)officially approved Lantheus'PYLARIFY?(Piflufolastat F 18,18 F-labeled imaging agent),which can be used for positron emission computed tomography(PET)of prostate-specific membrane antigen(PSMA)-positive lesions in prostate cancer patients to accurately identify prostate cancer with suspected metastasis or recurrence.Piflufolastat F 18 is approved by FDA for two indications.The first is the initial staging for suspected metastatic lesions in men with newly diagnosed prostate cancer.The second is restaging,with the goal of identifying lesions in the setting of biochem ical recurrence.

Background/Aims: Despite the high efficacy of direct-acting antivirals (DAAs), approximately 1–3% of hepatitis C virus (HCV) patients fail to achieve a sustained virological response. We conducted a nationwide study to investigate risk factors associated with DAA treatment failure. Machine-learning algorithms have been applied to discriminate subjects who may fail to respond to DAA therapy. Methods: We analyzed the Taiwan HCV Registry Program database to explore predictors of DAA failure in HCV patients. Fifty-five host and virological features were assessed using multivariate logistic regression, decision tree, random forest, eXtreme Gradient Boosting (XGBoost), and artificial neural network. The primary outcome was undetectable HCV RNA at 12 weeks after the end of treatment. Results: The training (n=23,955) and validation (n=10,346) datasets had similar baseline demographics, with an overall DAA failure rate of 1.6% (n=538). Multivariate logistic regression analysis revealed that liver cirrhosis, hepatocellular carcinoma, poor DAA adherence, and higher hemoglobin A1c were significantly associated with virological failure. XGBoost outperformed the other algorithms and logistic regression models, with an area under the receiver operating characteristic curve of 1.000 in the training dataset and 0.803 in the validation dataset. The top five predictors of treatment failure were HCV RNA, body mass index, α-fetoprotein, platelets, and FIB-4 index. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the XGBoost model (cutoff value=0.5) were 99.5%, 69.7%, 99.9%, 97.4%, and 99.5%, respectively, for the entire dataset. Conclusions Machine learning algorithms effectively provide risk stratification for DAA failure and additional information on the factors associated with DAA failure.

Objective To observe the application effect of transcutaneous acupoint electrical stimulation in the psychological craving and protracted abstinence symptoms of alcohol-dependent patients. Methods A total of 120 male alcohol-dependent patients who completed the acute alcohol withdrawal phase and were hospitalized in the Department of Alcoholism in Hunan Brain Hospital were selected as the study subjects. They were divided into conventional drug group, transcutaneous acupoint electrical stimulation group and placebo group according to different treatment methods, with 40 patients in each group. The conventional drug group was treated with benzodiazepine drugs for replacement and reduction and supportive symptomatic treatment. The transcutaneous acupoint electrical stimulation group was treated with conventional treatment combined with transcutaneous acupoint electrical stimulation. The placebo group was treated with conventional treatment combined with simulated transcutaneous acupoint electrical stimulation. The Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), Alcohol Urge Questionnaire (AUQ), Visual Analogue Scale (VAS), Pittsburgh Sleep Quality Index (PSQI) score and recurrence conditions were compared before and after treatment among the three groups. Results After treatment, the SAS, SDS, AUQ and VAS scores of the three groups were lower than those before treatment, and the above scores of the transcutaneous acupoint electrical stimulation group were lower than those of the conventional drug group and placebo group (P < 0.05). After treatment, the scores of sleep quality, the time to fall asleep, sleep duration, sleep efficiency, sleep disturbance, hypnotic drugs, daytime dysfunction and total PSQI score of the three groups were lower than those before treatment, and the above scores of the transcutaneous acupoint electrical stimulation group were lower than those of the conventional drug group and placebo group (P < 0.05). The recurrence rate of the transcutaneous acupoint electrical stimulation group was lower than that of the conventional drug group and placebo group (P < 0.05). Conclusion Compared with conventional treatment and simulated transcutaneous electrical stimulation, transcutaneous acupoint electrical stimulation is more effective in reducing the severity of protracted abstinence symptoms such as anxiety, depression and insomnia, and is also beneficial in reducing patients' psychological craving, thereby reducing the recurrence rate.

Neuropathic pain(NP) has similar phenotypes but different sequential neuroinflammatory mechanisms in the pathological process. It is of great significance to inhibit the initiation of neuroinflammation, which has become a new direction of NP treatment and drug development in recent years. Mongolian drug Naru-3 is clinically effective in the treatment of trigeminal neuralgia, sciatica, and other NPs in a short time, but its pharmacodynamic characteristics and mechanism of analgesia are still unclear. In this study, a spinal nerve ligation(SNL) model simulating clinical peripheral nerve injury was established and the efficacy and mechanism of Naru-3 in the treatment of NPs was discussed by means of behavioral detection, side effect evaluation, network analysis, and experimental verification. Pharmacodynamic results showed that Naru-3 increased the basic pain sensitivity threshold(mechanical hyperalgesia and thermal radiation hyperalgesia) in the initiation of SNL in animals and relieved spontaneous pain, however, there was no significant effect on the basic pain sensitivity threshold and motor coordination function of normal animals under physiological and pathological conditions. Meanwhile, the results of primary screening of target tissues showed that Naru-3 inhibited the second phase of injury-induced nociceptive response of formalin test in mice and reduced the expression of inflammatory factors in the spinal cord. Network analysis discovered that Naru-3 had synergy in the treatment of NP, and its mechanism was associated with core targets such as matrix metalloproteinase-9(MMP9) and interleukin-1β(IL-1β). The experiment further took the dorsal root ganglion(DRG) and the stage of patho-logical spinal cord as the research objects, focusing on the core targets of inducing microglial neuroinflammation. By means of Western blot, immunofluorescence, agonists, antagonists, behavior, etc., the mechanism of Naru-3 in exerting NP analgesia may be related to the negative regulation of the MMP9/IL-1β signaling pathway-mediated microglia p38/IL-1β inflammatory loop in the activation phase. The relevant research enriches the biological connotation of Naru-3 in the treatment of NP and provides references for clinical rational drug use.
