Objective To analyze the adverse reaction reports (ADRs) of drug-induced liver injury in recent ten years, explore the characteristics and related rules of drug-induced liver injury, and provide reference for clinical safe drug use. Methods ADRs in our hospital from 2011 to 2021 which belonged to drug-induced liver injuries were collected, and Pareto analysis was carried on. Results In 259 ADR reports, the most common type of drug-induced liver injury was hepatocellular injury (37.84%). The age of drug-induced liver injury was mainly over 46 years, totaling 195 (75.28%). Drugs were mainly distributed in cardiovascular system medicine (44.02%), anti-infective medicine (23.94%)and anti-tumor medicine (11.58%). Among the cardiovascular drugs, atorvastatin calcium 40mg and over 40mg were the highest proportion, with 53 cases (46.49%). The main anti-infectious drugs were cephalosporins (29.03%), carbapenem (19.35%), antifungal (17.74%)and quinolones (11.29%). Adverse reactions occurred within 6 days (69.88%), the duration of adverse reactions was 1-2 weeks (31.66%), and most patients were improved (47.88%) or cured (37.07%). Conclusion For middle-aged and elderly patients, when the application of cardiovascular system drugs, anti-infective drugs or anti-tumor drugs, it is necessary to monitor the liver function changes of patients for at least 6 days. If there are abnormalities, the drugs should be stopped or given treatment in time, to avoid the progress of drug-induced liver injury.

Objective:
To investigate the effect of integrin α5 on the expression of NOD-like receptor thermal protein domain associated protein 3 (NLRP3) in periodontal ligament fibroblasts (PDLFs) within an inflammatory microenvironment.
Methods:
This study was approved by the Ethics Committee of Laboratory animals. After rat PDLFs were treated with LPS (0.5, 5, and 50 µg/mL) for 24 h, the primary medium was discarded and replaced with serum-free culture medium. After 24 h, the supernatant was collected and mixed with DMEM medium containing 10% exosome-free serum at a volume ratio of 1:1 to obtain conditioned medium (CM). The groups were labeled as the 0.5-CM, 5-CM, and 50-CM groups. In addition, PDLFs cultured in DMEM medium containing 10% exosome-free serum were considered the 0-CM group. PDLFs were cultured with the above CM. In the inhibitor group, PDLFs were cultured in 0-CM containing different concentrations of integrin α5 inhibitor ATN-161 (0, 0.025, 0.25, 2.5, 25, and 250 μg/mL). The effect of CM and integrin α5 inhibitor ATN-161 on cell viability was assessed using the CCK-8 assay. According to the CCK-8 results, in further inhibitor intervention experiments, PDLFs were cultured in 0-CM, 5-CM (without/with 25 μg/mL ATN-161), and 0-CM containing 25 μg/mL ATN-161, which were labeled as the 0-CM, 5-CM, ATN-161+5-CM, and ATN-161 groups, respectively. The expression changes of integrin α5 and NLRP3 were detected using Western blot and qRT-PCR techniques. For in vivo experiments, 24 rats were randomly divided into four groups (n=6). The control group contained healthy rats that received no treatment. The rats in the other three groups were injected with 40 µL of 0-CM containing 25 μg/mL ATN-161 or 5-CM (without or with 25 μg/mL ATN-161) on the palatal side of the left maxillary first molar every three days; these groups were classified as the ATN-161, 5-CM, and ATN-161+5-CM groups, respectively. On the 30th day, the left maxillary tissue of rats was used for Micro-CT, HE staining, and immunohistochemical detection.
Results :
The CCK-8 assay showed that CM, 25 μg/mL ATN-161, and ATN-161 concentrations below 25 μg/mL had no significant effect on cell viability at 12 h and 24 h (P > 0.05). 50-CM and 25 μg/mL ATN-161 significantly inhibited cell viability at 48 h (P < 0.05). For in vitro experiments, compared to the 0-CM group, both the protein and mRNA levels of integrin α5 and NLRP3 were significantly increased in rat PDLFs in the 5-CM group (P < 0.05). Intervention with 25 μg/mL ATN-161 significantly attenuated the enhancement of 5-CM on the expression of integrin α5 and NLRP3 (P < 0.05). For in vivo experiments, compared to the control group, alveolar bone resorption and periodontal inflammatory cell infiltration were significantly increased in the 5-CM and ATN-161+5-CM groups, and the expression of integrin α5 and NLRP3 was significantly increased (P < 0.01). However, compared to the 5-CM group, the ATN-161+5-CM group had less alveolar bone resorption and fewer periodontal inflammatory cells. Further, the expression of integrin α5 and NLRP3 was significantly reduced (P < 0.01).
Conclusion
In vitro and in vivo experiments showed that integrin α5 mediated NLRP3 expression in PDLFs under an inflammatory microenvironment. ATN-161 inhibited the expression of integrin α5, thus significantly downregulating the expression of NLRP3, which plays a role in inhibiting inflammation.

ObjectiveTo explore the molecular mechanism of Buzhong Yiqitang in attenuating cisplatin resistance in non-small cell lung cancer (NSCLC) by inducing ferroptosis via poly(rC)-binding protein 1 (PCBP1). MethodsThe serum containing Buzhong Yiqitang was prepared and cisplatin-resistant human non-small cell lung cancer (NSCLC) cells (A549/DDP) were cultured and randomly grouped as follows: Blank (10% blank serum), model (10% blank serum+20 mg·L-1 cisplatin), Buzhong Yiqitang (10% serum containing Buzhong Yiqitang+20 mg·L-1 cisplatin), Fe-1 (10% blank serum+20 mg·L-1 cisplatin+5 μmol·L-1 Fe-1), and Buzhong Yiqitang+Fe-1 (10% serum containing Buzhong Yiqitang+20 mg·L-1 cisplatin+5 μmol·L-1 Fe-1). Firstly, PCR Array was used to screen ferroptosis-related genes regulated by Buzhong Yiqitang, and PCBP1 was identified as the target for studying the attenuation of cisplatin resistance by Buzhong Yiqitang. Subsequently, the median inhibitory concentration (IC50) of cisplatin in each group was determined by the cell counting kit-8 (CCK-8) method and the resistance index (RI) was calculated. The ultrastructure of A549/DDP cells in each group was observed by transmission electron microscopy. The protein levels of PCBP1 and glutathione peroxidase 4 (GPX4) were determined by Western blot. The lipid reactive oxygen species (ROS) content in each group was determined by the C11-BODIRY 581/591 fluorescence probe. The ferrous ion assay kit was used to measure the ferrous ion content in each group. The malondialdehyde (MDA) assay kit was used to determine the MDA content in each group. ResultsCompared with model group, the IC50 of cisplatin and the RI of A549/DDP cells decreased in the Buzhong Yiqitang group (P<0.05) but increased in the Fe-1 group (P<0.05). The IC50 of cisplatin and the RI of A549/DDP cells in the Buzhong Yiqitang+Fe-1 group were lower than those in the Fe-1 group (P<0.05). Compared with the model group, the Buzhong Yiqitang group showed obvious mitochondrial ferroptosis, while the mitochondrial damage became less obvious after Fe-1 treatment. Compared with that in the Fe-1 group, the mitochondrial ferroptosis was aggravated after the intervention with Buzhong Yiqitang. Compared with blank group, the model group showed down-regulated expression levels of PCBP1 and GPX4 (P<0.05) and increased content of lipid ROS, ferrous ions, and MDA (P<0.05) in A549/DDP cells. Compared with model group, the Buzhong Yiqitang group showed down-regulated expression levels of PCBP1 and GPX4 (P<0.05) and increased content of lipid ROS, ferrous ions, and MDA (P<0.05), while the Fe-1 group showed up-regulated expression levels of PCBP1 and GPX4 (P<0.05) and reduced content of lipid ROS, ferrous ions, and MDA (P<0.05). Compared with the Fe-1 group, the Buzhong Yiqitang+Fe-1 group showed down-regulated expression levels of PCBP1 and GPX4 and increased content of lipid ROS, ferrous ions, and MDA (P<0.05). ConclusionBuzhong Yiqitang attenuated cisplatin resistance in NSCLC by regulating PCBP1 to induce ferroptosis.

ObjectiveTo investigate the mechanism of Buzhong Yiqitang in attenuating cisplatin resistance in non-small cell lung cancer by observing the effects of Buzhong Yiqitang on endoplasmic reticulum stress-related molecules in human lung adenocarcinoma cells (A549) and cisplatin-resistant cells in human lung adenocarcinoma cells (A549/DDP) via the nuclear factor E2-related factor 2(Nrf2)/reactive oxygen species(ROS) pathway. MethodsThe serum containing Buzhong Yiqitang was prepared and A549 cells and A549/DDP cells were cultured. The cells were randomized into groups A (A549 cells+blank serum), B (A549 cells+20 mg·L-1 cisplatin+blank serum), C (A549 cells+20 mg·L-1 cisplatin+10% Buzhong Yiqitang-containing serum), D (A549/DDP cells+blank serum), E (A549/DDP cells+20 mg·L-1 cisplatin+blank serum), and F (A549/DDP cells+20 mg·L-1 cisplatin+10% Buzhong Yiqitang-containing serum). The cell counting kit-8 (CCK-8) method was used to detect the half maximal inhibitory concentration (IC50) of cisplatin. The protein levels of Nrf2 and p-Nrf2 were determined by Western blotting. The DCFH-DA fluorescent probe was used to measure the content of reactive oxygen species (ROS) in each group. The protein levels of glucose-regulated protein 78 (GRP78), activated transcription factor 6 (ATF6), and C/EBP-homologous protein (CHOP) were determined by Western blot. ResultsCompared with group B, group C showed a reduction in IC50 of cisplatin (P<0.05), which held true in group E compared with group F (P<0.05). Moreover, the IC50 of cisplatin to A549/DDP cells was higher than that to A549 cells before and after Buzhong Yiqitang intervention (P<0.05). Compared with group A, group B showed up-regulated protein levels of Nrf2 and p-Nrf2 (P<0.05). Compared with group B, group C showed down-regulated protein levels of Nrf2 and p-Nrf2 (P<0.05). Compared with group D, group E showed up-regulated protein levels of Nrf2 and p-Nrf2 (P<0.05), which, however, were significantly down-regulated in group F (P<0.05). The ROS content and the protein levels of GRP78, ATF6, and CHOP followed a descending trend of group C > group B > group A in A549 cells and group F > group E > group D in A549/DDP cells (P<0.05). Moreover, the ROS content and the protein levels of GRP78, ATF6, and CHOP in A549 cells were higher than those in A549/DDP cells before and after Buzhong Yiqitang intervention (P<0.05). ConclusionBuzhong Yiqitang may regulate endoplasmic reticulum stress via the Nrf2/ROS pathway to attenuate cisplatin resistance in non-small cell lung cancer.

In the process of tumor chemotherapy, the emergence of multi-drug resistance (MDR) has always been a thorny problem, which is a result of the joint action of the host, tumor cells, and the immune microenvironment. Tumor cells can escape the toxicity of chemotherapeutic drugs through multiple pathways, being easy to produce drug resistance. MDR greatly restricts the effect of chemotherapeutic drugs on tumor cells and affects their therapeutic effects. Traditional Chinese medicine (TCM) has the unique advantages of multi-target, multi-pathway and individualized treatment. The TCM treatment of tumors emphasizes regulating Yin and Yang, as well as reinforcing healthy Qi and dispelling pathogen. In recent years, TCM has demonstrated remarkable efficacy in the treatment of tumors and the amelioration of multi-drug resistance. TCM not only can target the phenomenon of MDR but also greatly weakens the side effects of the patients after the chemotherapy, thus improving the survival quality and rate of the patients. Accordingly, many patients adopt TCM as an adjuvant therapy during or after chemotherapy. The binding of TCM to targets can reverse the drug resistance of various tumors, which has become an emerging research highlight. From the regulatory mechanism of TCM on MDR of tumors, this paper introduces the mechanisms by which tumor cells continue to grow, proliferate, and metastasize by adjusting the intracellular drug concentration, altering or utilizing the tumor microenvironment, and affecting the cell death mode to achieve the resistance to chemotherapeutic drugs. In this regard, the active ingredients and compound prescriptions of TCM can increase the sensitivity of chemotherapeutic drugs by down-regulating drug transporters, improving the tumor microenvironment, and modulating the drug resistance pathways associated with apoptosis, autophagy, ferroptosis, or pyroptosis. The aim of this paper is to explore more clinical practical value of TCM in the treatment of tumors and provide exploratory ideas and a theoretical basis for the future research on tumors and MDR.

Objective To explore the effects of empathy technology on emotion regulation, sleep improvement and quality of life improvement in patients with first benign paroxysmal positional vertigo (BPPV). Methods A total of 100 patients with the first BPPV in The Second Affiliated Hospital of Naval Medical University from December 2023 to November 2024 were selected, and were divided into control group and observation group by random number table method. The patients in both groups received routine reduction treatment and outpatient follow-up every 3 months after discharge, with a total of 4 follow-up visits. The patients in control group received routine health and psychological education; on this basis, the patients in observation group received empathy technique intervention before, during, after reposition and during follow-up. The emotion, sleep and quality of life scales were evaluated before intervention and at the 4th outpatient follow-up. The recurrence rates of BPPV within 1 year after discharge were compared between the two groups. Results One year after discharge, self-rating anxiety scale (SAS), self-rating depression scale (SDS), symptom checklist 90 (SCL-90) and Pittsburgh sleep quality index (PSQI) scores in the observation group were lower than those in the control group, and multi-dimensional quality of life scores in the observation group was higher than that in the control group. These differences were statistically significant (P<0.05). The recurrence rate of BPPV in the observation group was lower than that in the control group 1 year after discharge (P<0.05). Conclusions Empathy technology intervention can further improve emotion, sleep quality, and quality of life, but reduce disease recurrence rate in first BPPV patients receiving routine treatment and health education, so it can be widely used in clinical practice.

To analyze the disease burden, temporal trends, and attributable risk factors of early-onset female breast cancer (EOBC) in China and globally from 1990 to 2021. Data on the absolute numbers and crude rates of incidence, mortality, and disability-adjusted life years (DALYs) for EOBC (diagnosis age < 50 years) in China and globally were extracted from the Global Burden of Disease (GBD) 2021 database. Attributable DALY proportions for five risk factors (smoking, alcohol use, physical inactivity, high red meat consumption, elevated fasting plasma glucose) and all combined risk factors were obtained. Joinpoint regression analysis was performed to assess temporal trends in age-standardized rates, quantified by annual percentage change (APC) and average annual percentage change (AAPC). From 1990 to 2021, age-standardized incidence rates of EOBC increased significantly in both China (AAPC=2.25%) and globally (AAPC=0.64%; pairwise comparison, China's age-standardized EOBC incidence is rising rapidly and approaching global levels, while mortality and DALY rates have increased over the past decade, underscoring persistent challenges in disease control. Future efforts should prioritize expanding the coverage of breast cancer screening programs, optimizing screening protocols, and enhancing public awareness of cancer prevention to mitigate the growing burden of EOBC in China.

ObjectiveTo understand the whole genome characteristics and the information for genetic evolution in the two coxsackievirus A2 (CVA2) strains isolated from patients with herpangina in Shanghai, and to provide a scientific basis for the prevention and treatment of herpetic angina. MethodsTwo CAV2 strains isolated from patients with herpetic angina in Shanghai were performed whole genome sequencing and analysis for phylogenetics, nucleotide homology, and evolution. ResultsA phylogenetic analysis of the VP1 region revealed that the two Shanghai strains both belonged to CVA2 genotype D, with the highest homology to OL357660, a strain from Yunnan. The average nucleotide identity (ANI) of the whole genome between the two Shanghai strains was 98.88%, and the ANI of the whole genome comparisons to other CVA2 genotype D strains and CVA2 genotypes A-C strains ranged from 84.64% to 97.42% and from 79.21% to 84.20%, respectively. The two Shanghai strains had low homology in the 3D region compared to the existing CVA2 strains. The phylogenetic analysis and sliding window nucleotide similarity analysis indicated that the two Shanghai strains and the Yunnan OL357660 strain might constitute a new genetic lineage. ConclusionThe two CVA2 strains isolated for the first time in Shanghai are assigned to genotype D (GenBank: PQ130039 and PQ130040), which is identical to the existing subtype prevalent in China. As represented by the Shanghai strains, a new CVA2 genetic lineage is been identified. This study has enriched the data on genetic evolution and genetic variation of CVA2 in Shanghai, indicating the requirement to strengthen surveillance for the epidemiological pattern of CVA2.
