ObjectiveTo investigate and analyze an outbreak of rotavirus infectious diarrhea in a prison in Chongqing Municipality, to provide a basis for adult rotavirus surveillance and prevention, and to explore the public health problems in special settings. MethodsA retrospective survey was conducted to collect and analyze data on individual cases with diarrheal disease on-site. The clinical characteristics, as well as the temporal, spatial and geographical distribution patterns of the epidemic were described. Multi-pathogen detection tests were conducted both on diarrhea cases and environmental samples, with viral genotyping performed on positive samples. A case-control analysis was performed to identify the causes of the outbreak, and an SEIR model was adopted to predict the outbreak trend and evaluate the effectiveness of interventions. ResultsA total of 65 cases were found among the inmates, with an attack rate of 2.03%. The predominant clinical manifestations included diarrhea (89.23%), watery stool (73.85%), and dehydration (18.46%). The epidemic curve indicated a “human-to-human” transmission pattern, with an average incubation period of 5‒6 days. The attack rates among chefs in the main canteen (80.00%, 8/10) and caterers (28.33%, 17/60) were significantly higher than those of other inmates (P<0.05). Multi-pathogen polymerase chain reaction (PCR) testing detected positive for group A rotavirus, with the viral genotyping identified as G9P [8] strain. Factors such as unprotected "bare-handed" food distribution among cases with diarrhea (OR=9.512, 95%CI: 4.261‒21.234) and close contact with diarrhea cases (OR=3.656, 95%CI: 1.719‒7.778) were the possible cause of the outbreak. The SEIR model (r0=5, α=0.3, β1=0.08, β2=0.04) was constructed using prison inmates as susceptible population, aiming at fitting the initial transmission trend of the outbreak, and the epidemic rate declined rapidly after intervention measures were implemented (rt≈0). ConclusionThis rare rotavirus infection diarrhea outbreak among adults in confined settings suggests that the construction of public health prevention and control systems in prison may be overlooked. Cross infection during meal processing and distribution in the canteens of such settings is likely to be the cause of the outbreak. Given the potential neglect of public heath system construction in special settings, it is imperative to enhance the surveillance and monitoring of rotavirus and other intestinal multi-pathogens among adults, as well as the construction of public health prevention and control systems in these special settings.

Homo- or heterodimeric compounds that affect dimeric protein function through interaction between monomeric moieties and protein subunits can serve as valuable sources of potent and selective drug candidates. Here, we screened an in-house dimeric natural product collection, and panepocyclinol A (PecA) emerged as a selective and potent STAT3 inhibitor with profound anti-tumor efficacy. Through cross-linking C712/C718 residues in separate STAT3 monomers with two distinct Michael receptors, PecA inhibits STAT3 DNA binding affinity and transcription activity. Molecular dynamics simulation reveals the key conformation changes of STAT3 dimers upon the di-covalent binding with PecA that abolishes its DNA interactions. Furthermore, PecA exhibits high efficacy against anaplastic large T cell lymphoma in vitro and in vivo, especially those with constitutively activated STAT3 or STAT3Y640F. In summary, our study describes a distinct and effective di-covalent modification for the dimeric compound PecA to disrupt STAT3 function.

OBJECTIVE To provide evidence for the safe clinical application of Trastuzumab for injection. METHODS Reports of adverse drug reaction (ADR) related to Trastuzumab for injection submitted in Beijing from June 2018 to May 2023 were collected. Statistical analyses were performed using SPSS 25.0 software. The gender and age of patients with ADRs, outcome, types of cancer, and the time of onset, severity, affected organs/systems of ADRs were included for analyses. The univariate Logistic regression analysis was conducted on patient fever and ADR prognosis. RESULTS A total of 195 patients with 318 instances of ADRs were included in the study. Women (87.69%) and patients aged 60-69 (33.85%) were more likely to experience ADRs. Breast cancer dominated (86.67%) in terms of cancer types; in terms of outcomes, most patients (67.69%) showed improvement, and some patients (27.69%) achieved full recovery. Overall, 68.72% of ADRs mainly occurred on the day of medication, and 95.38% of ADRs were of “moderate” severity. The most affected organs/systems were general diseases and various reactions at the administration site (40.57%), with chills (18.87%) and fever (18.24%) being the most common. Univariate Logistic regression analysis showed that fever mostly occurred within 1 day of medication (OR=5.63, 95%CI was 2.26-14.02, P< 0.001). The time of onset of ADR greater than 1 day was a risk factor for poor ADR prognosis (OR=20.08, 95%CI was 2.45- 164.43, P=0.005), mainly manifesting as bone marrow suppression and liver function abnormalities. Neutrophilia, cardiorespiratory arrest, and mixed liver damage were new ADRs not recorded in the drug’s instructions. CONCLUSION Women and patients aged ≥60 are high-risk groups for ADRs of Trastuzumab for injection. Chills and fever remain the most common ADRs of this drug, and these symptoms mostly occur within 1 day of medication, which have better prognoses. Close attention should be paid to the patient’s temperature changes on the day of drug infusion, with timely intervention. Regular monitoring of the patient’s hematological indicators is necessary to detect any bone marrow suppression and liver function abnormalities after medication.
