OBJECTIVE To analyze the clinical characteristics of Stevens-Johnson syndrome （SJS） and toxic epidermal necrolysis （TEN） induced by tislelizumab， providing evidence for clinical medication safety. METHODS Case reports of tislelizumab-related SJS/TEN were retrieved from CNKI， VIP， Wanfang Data， PubMed， ScienceDirect， and Embase. Descriptive analysis was performed. RESULTS Seventeen cases from 17 publications were included （SJS 4 cases， TEN 13 cases）. Among them， there were 10 males and 7 females. Twelve patients were aged between 70 and 79 years. The predominant tumor type was lung cancer （10 cases）. Thirteen patients received combination therapy with chemotherapeutic drugs. The median onset time of SJS/ TEN was 26 （4， 104） days. Nine patients developed SJS/TEN after the first administration of the drug. Sixteen patients exhibited prodromal rash symptoms， primarily characterized by severe skin damage such as skin detachment， accompanied by mucosal injury. Sixteen patients improved after symptomatic treatment， while one patient died. CONCLUSIONS Tislelizumab-associated SJS/TEN risk is higher in elderly patients， males， those with lung cancer and those receiving combination chemotherapy. Mucosal lesions and atypical rashes may indicate the early onset of SJS/TEN. During clinical use， pharmaceutical care can be carried out through measures such as identifying high-risk populations， closely monitoring skin symptoms from the first administration to the fifth treatment cycle， and enhancing patient education. When relevant symptoms occur， the medication should be promptly discontinued and symptomatic treatment should be administered to ensure the patient’s medication safety.

AIM: To explore the therapeutic effect of oral Xuefu Zhuyu Pill combined with intravitreal injection of aflibercept in the treatment of retinal vein occlusion(RVO).METHODS: A total of 80 patients(80 eyes)with RVO admitted to our hospital from January 2021 to March 2024 were prospectively selected. According to the treatment method, they were divided into a control group of 40 patients treated with intravitreal injection of aflibercept, and an observation group of 40 patients treated with oral Xuefu Zhuyu Pill combined with intravitreal injection of aflibercept. The efficacy, TCM syndrome score, retinal microcirculation parameters, macular edema(ME), and adverse reactions were compared between the two groups of patients in the treatment of RVO.RESULTS: All patients have completed follow-up. The clinical effective rate of the observation group after treatment was 95%, obviously higher than that of the control group(80%; χ2=4.114, P=0.043). After treatment for 3 mo, the traditional Chinese medicine syndrome scores, foveal avascular area(FAZ)area, FAZ circumference, macular central retinal thickness, and neovascularization leakage area of both groups decreased, the overall blood flow density of the superficial capillary plexus(SCP)and deep capillary plexuses(DCP)increased, and the observation group showed better results than the control group(all P<0.05). There was no statistically significant difference in the occurrence of adverse reactions between the two groups during the treatment period(P>0.05).CONCLUSION: Oral administration of Xuefu Zhuyu Pill combined with intravitreal injection of aflibercept in the treatment of RVO can improve retinal microcirculation, enhance vision, restore ocular blood circulation, improve bleeding, promote ME absorption, and improve clinical efficacy.

This article explores the interaction between aspirin and safflower yellow injection from the perspective of pharmacokinetics, combined with pharmacological indicators such as anticoagulation. Quantitative HPLC analysis was performed for the detection of salicylic acid in plasma samples, and the pharmacokinetic effects of aspirin in combination with safflower yellow injection on aspirin’s hydrolyzed product salicylic acid was evaluated. Thromboxane B2 (TXB2) and 6-keto prostaglandin F1 in plasma were determined using enzyme-linked immunosorbent assay and fully automated biochemical analyzer α (6-keto-PGF1) α）, and the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and serum creatinine (Scr) were tested to evaluate the anticoagulant effect and safety indicators after long-term combined use of the two drugs, including liver and kidney function and cardiac pathological examination. The results showed that, compared with the aspirin group, there was no significant difference (P>0.05) in the plasma pharmacokinetic parameters of rats with combined use of safflower yellow injection. In addition, the plasma TXB2 in the combination group was significantly reduced compared to the aspirin group (P<0.01), yet with no significant difference for 6-keto-PGF1 α (P>0.05). There was no statistically significant difference in the levels of serum BUN, Scr, AST, and ALT between the two groups before and after treatment (P>0.05). These results suggest that the combination of aspirin and safflower yellow injection does not cause significant change in the blood concentration of salicylic acid. It does not affect the antiplatelet effect of aspirin.

Modulating Tankyrases (TNKS), interactions with USP25 to promote TNKS degradation, rather than inhibiting their enzymatic activities, is emerging as an alternative/specific approach to inhibit the Wnt/β-catenin pathway. Here, we identified UAT-B, a novel neoantimycin analog isolated from Streptomyces conglobatus, as a small-molecule inhibitor of TNKS-USP25 protein-protein interaction (PPI) to overcome multi-drug resistance in colorectal cancer (CRC). The disruption of TNKS-USP25 complex formation by UAT-B led to a significant decrease in TNKS levels, triggering cell apoptosis through modulation of the Wnt/β-catenin pathway. Importantly, UAT-B successfully inhibited the CRC cells growth that harbored high TNKS levels, as demonstrated in various in vitro and in vivo studies utilizing cell line-based and patient-derived xenografts, as well as APC^min/+ spontaneous CRC models. Collectively, these findings suggest that targeting the TNKS-USP25 PPI using a small-molecule inhibitor represents a compelling therapeutic strategy for CRC treatment, and UAT-B emerges as a promising candidate for further preclinical and clinical investigations.

Background Adverse drug reactions (ADRs) to sodium dimercaptosulphonate (DMPS) mercury removal treatment have been reported in occupational mercury poisoning. In recent years, the number of cases of mercury poisoning due to mercury-containing cosmetics has been increasing, and ADRs to the use of DMPS are common in clinical practice. Objective To investigate the occurrence of ADRs and the influencing factors in patients with chronic mercury poisoning and mercury exposure treated with DMPS for mercury removal. Methods Patients treated with DMPS due to mercury poisoning at the Occupational Disease Department of Nanjing Prevention and Treatment Center for Occupational Diseases from June 2017 to December 2023 were included in the study. Information on demographics, baseline characteristics, and treatment regimens was collected at admission. Information on secondhand smoke, place of residence, and blood groups not collected at admission was collected in follow-up. The patients were divided into two groups according to whether ADRs occurred after the use of DMPS and were compared for clinical characteristics, and the influencing factors related to the occurrence of ADRs after DMPS treatment were analyzed by binary logistic regression. Results A total of 72 patients were enrolled in the study, of which 26 reported ADRs during mercury removal. A total of 29 ADRs occurred, mainly rash in 11 cases (37.9%), fever in 5 cases (17.2%), and nausea in 4 cases (13.8%). Most ADRs occurred in the second course (7 cases, 26.9%) and the third course (9 cases, 34.6%). Of the 22 non-menopausal women who experienced ADRs, 13 (59.1%) used DMPS in the week prior to menstruation. The logistic regression analysis showed that smoking (OR=27.911, 95%CI: 2.835, 725.809) and blood type O (OR=6.885, 95%CI: 2.014, 26.896) were associated with elevated occurrence of ADRs after DMPS treatment. Conclusions The probability of ADRs after DMPS treatment is not low, but mild presentations are predominant and resolved with immediate treatment, with a favourable prognosis. The O blood group, smoking individuals, and female patients using DMPS one week before menstruation may be more prone to ADRs.

Objective: To explore the relationship between air pollutants and pediatric outpatient volumes in Baoshan District, Shanghai Municipality. Methods: Data of meteorological factors, air pollutants and pediatric outpatient volumes in four general hospitals were collected in Baoshan District from 2015 to 2019, and a generalized additive model was used to fit the Poisson-like distribution. The exposure-response relationship between fine particulate matter (PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3) and total pediatric outpatient volumes and pediatric respiratory outpatients. Results: The median of the average daily temperature and relative humidity were 18.7 (interquartile range, 14.4) ℃ and 74.5% (interquartile range, 18.0%) in Baoshan District from 2015 to 2019, respectively. The median of the average daily concentrations of PM2.5, SO2, NO2 and O3 were 35.0 (interquartile range, 35.0), 11.0 (interquartile range, 7.0), 45.0 (interquartile range, 31.8) and 84.5 (interquartile range, 50.0) μg/m3, respectively. The median of the average daily total and respiratory pediatric outpatient volumes were 680 (interquartile range, 246) and 392 (interquartile range, 253). Spearman rank correlation analysis showed that temperature, relative humidity, PM2.5, SO2, NO2 and O3 were associated with total and respiratory pediatric outpatient volume (all P<0.05). Under the single pollutant model, the excess risk of total and respiratory pediatric outpatient volume due to PM2.5 (ER=0.318, 0.257), SO2 (ER=1.610, 2.546), and NO2 (ER=0.808, 0.839) reached the maximum effect on the same day, and the effect of O3 (ER=0.102, 0.222) reached its maximum at the first day of lag. Under the multi-pollutant model, after O3, SO2, NO2 and PM2.5 were introduced, a exposure-response relationship between air pollutants and total pediatric outpatient volumes was the largest on the sixth day after the lag (ER=0.419). There was no exposure-response relationship between air pollutants and respiratory pediatric outpatient volumes. Conclusion PM2.5, SO2, NO2 and O3 are associated with total and respiratory pediatric outpatient volumes, and the lag effects due to different air pollutants are different.

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of national bloodstream infection Bacterial Resistant Investigation Collaborative System（BRICS）were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:During the study period，9 035 strains of Gram-negative bacteria were collected from 51 hospitals，of which 7 895（87.4%）were Enterobacteriaceae and 1 140（12.6%）were non-fermenting bacteria. The top 5 bacterial species were Escherichia coli（ n=4 510，49.9%）， Klebsiella pneumoniae（ n=2 340，25.9%）， Pseudomonas aeruginosa（ n=534，5.9%）， Acinetobacter baumannii complex（ n=405，4.5%）and Enterobacter cloacae（ n=327，3.6%）. The ESBLs-producing rates in Escherichia coli， Klebsiella pneumoniae and Proteus spp. were 47.1%（2 095/4 452），21.0%（427/2 033）and 41.1%（58/141），respectively. The prevalence of carbapenem-resistant Escherichia coli（CREC）and carbapenem-resistant Klebsiella pneumoniae（CRKP）were 1.3%（58/4 510）and 13.1%（307/2 340）；62.1%（36/58）and 9.8%（30/307）of CREC and CRKP were resistant to ceftazidime/avibactam combination，respectively. The prevalence of carbapenem-resistant Acinetobacter baumannii（CRAB）complex was 59.5%（241/405），while less than 5% of Acinetobacter baumannii complex was resistant to tigecycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa（CRPA）was 18.4%（98/534）. There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of main Gram-negative bacteria resistance among different regions，with statistically significant differences in the prevalence of CRKP and CRPA（ χ2=20.489 and 20.252， P<0.001）. The prevalence of CREC，CRKP，CRPA，CRAB，ESBLs-producing Escherichia coli and Klebsiella pneumoniae were higher in provinicial hospitals than those in municipal hospitals（ χ2=11.953，81.183，10.404，5.915，12.415 and 6.459， P<0.01 or <0.05），while the prevalence of CRPA was higher in economically developed regions（per capita GDP ≥ 92 059 Yuan）than that in economically less-developed regions（per capita GDP <92 059 Yuan）（ χ2=6.240， P=0.012）. Conclusions:The proportion of Gram-negative bacteria in bloodstream infections shows an increasing trend，and Escherichia coli is ranked in the top，while the trend of CRKP decreases continuously with time. Decreasing trends are noted in ESBLs-producing Escherichia coli and Klebsiella pneumoniae. Low prevalence of carbapenem resistance in Escherichia coli and high prevalence in CRAB complex have been observed. The composition ratio and antibacterial spectrum of bloodstream infections in different regions of China are slightly different，and the proportion of main drug resistant bacteria in provincial hospitals is higher than those in municipal hospitals.

[Objective]To explore the role of estrogen and estrogen receptor (ER) in the pathogenesis and regulation of non-invasive fungal rhinosinusitis (NIFR).[Methods]Totally 60 patients with NIFS who met the inclusion criteria in Fuzhou Second General Hospital from November 2020 to November 2023 were selected as the NIFS group,while 30 healthy volunteers were recruited as the blank control group. Samples of each group were collected. The number of eosinophils and mast cells in each group were detected by HE staining;ER expression was detected by immunohistochemistry and immunofluorescence;mRNA expression levels of NF-κB,IKK and MASPIN were detected by qPCR;and protein expression levels of NF-κB,IKK and MASPIN were detected by immunohistochemistry and Western blot.[Results]In the NIFS group,the counts of eosinophils and mast cells were significantly increased respectively,compared with those in the control group,and the inter-group differences are statistically significant (P<0.01 and P<0.05,respectively). The Estrogen Receptor (ER) score in the NIFS group was significantly increased compared with that in the control group,and the inter-group differences are statistically significant (P<0.05). Additionally,the average high-density value in the NIFS group was significantly increased compared with that in the control group,and the inter-group differences are statistically significant (P<0.01). The expression levels of NF-κB,IKK,and MASPIN in the NIFS group were significantly increased respectively,compared with those in the control group,and the inter-group differences are statistically significant (P<0.01,P<0.05,and P<0.01,respectively). The mRNA expression levels of NF-κB,IKK,and MASPIN in the NIFS group were significantly increased,respectively,compared with those in the control group (P<0.01). Furthermore,the protein expression levels of NF-κB,IKK,and MASPIN in the NIFS group were increased,respectively,and the inter-group differences are statistically significant (P<0.01,P<0.01,and P<0.05,respectively).[Conclusion]Our results show that the significant increase in the number of eosinophils and mast cells,and in the expression levels of ER,NF-κB,IKK and MASPIN may indicate a significant increase in eosinophil and mast cell infiltration in ER positive patients,and suggest the involvement of estrogen and its receptors in the pathogenesis of NIFS.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.
