Objective To evaluate the safety and effectiveness of different doses of epidural oxycodone injection for traction reaction during cesarean sections to determine the optimal dose.Methods Totally 119 cases of parturients who underwent cesarean sections from October 2023 to May 2024 were selected and randomly divided into groups A,B,C and D.All four groups of lying-in women received epidural injection after the umbilical cord was cut.Groups A,B and C were given oxycodone 3 mg,5 mg and 7 mg respectively,and group D was given an equal amount of normal saline.The primary outcomes were documentation of maternal vital signs and traction reaction during the surgery.Secondary outcomes included patient-controlled intravenous analgesia(PCIA)times within 48 hours and documentation of any postoperative adverse events within 24 hours.Results The comparison of in-tra?operative vital signs among the four groups of patients revealed no statistically significant differences.In groups A,B and C the incidence of traction reactions was significantly lower at 20%,17.2%and 3.3%,respectively,compared to group D at 53.3%,showing statistically significant differences(P<0.05).Additionally,the inci?dence of traction reaction in group C was significantly lower than in group A(P<0.05).Groups A,B and C pro?duced significantly better results than group D in terms of the duration of anesthesia.PCIA presses were substan?tially less in groups A and C than in group D(P<0.05),and group C had a significantly higher total incidence of adverse events than group A and group D(P<0.05).Conclusions Epidural injection of 3 mg,5 mg and 7 mg oxycodone has been proved to significantly reduce traction reaction during cesarean sections while minimally im?pacting intraoperative vital signs.This intervention has the potential to extend the duration of anesthesia,decrease the frequency of PCIA presses.Among these,7 mg is the most effective but has the highest incidence of adverse effects,requiring carefully post?operative monitoring.

Pulmonary diseases, as a prevalent category of respiratory system disorders, have become a significant global public health concern. The increasing incidence of these diseases, caused by environmental pollution and occupational hazards, poses a substantial threat to human health and the overall quality of life. Mesenchymal stem cells (MSCs) are known for their remarkable immunomodulatory, anti-bacterial, and anti-apoptotic capabilities. Exosomes derived from MSCs, carrying a diverse array of proteins, lipids, nucleic acids, and other bio-active molecules, have demonstrated considerable therapeutic potential in treating pulmonary diseases, and have come to the forefront of medical research. This review summarized the therapeutic role of exosomes derived from various sources of mesenchymal stem cells in the context of pulmonary diseases, aiming to provide a robust foundation for their clinical application in diagnosis and treatment.

PANoptosis is a newly defined type of programmed cell death (PCD), which is triggered by a variety of stimuli and covers three known forms of PCD: apoptosis, pyroptosis and necroptosis. In physiological state, cell death plays an important protective role against pathogen invasion, but its over-activation may aggravate inflammatory response and cause tissue damage. Studies have shown that the occurrence and progression of acute lung injury/acute respiratory distress syndrome (ALI/ARDS), asthma, chronic obstructive pulmonary disease (COPD) and other lung diseases are closely related to PANoptosis. The purpose of this review is to deeply explore the molecular mechanism of PANoptosis and its regulatory factors in lung diseases, in order to discover potential therapeutic targets and provide new targets and innovative ideas for clinical treatment for lung diseases.

Objectives miR-207 has been identified as being expressed in natural killer (NK) cell exosomes that play a role in disease progression; however, to date, there are no studies specifically linking miR-207 to tuberculosis (TB). Methods Bioinformatics methods employed for prediction, followed by a dual luciferase reporter assay to determine whether lysosome-associated membrane protein 2 (LAMP2) is targeted by miR-207. The experiments were divided into four groups using the liposome transfection method (OP-LAMP2 group: co-transfected with miR-207 mimics and LAMP2 overexpression plasmid; EP group: co-transfected with mimics NC and null-loaded plasmid; siLAMP2 group: transfected with siLAMP2; and siLAMP2-NC group: transfected with siLAMP2-NC). TB infection was modeled using H37Ra-infected Ana-1 cells. The impact of LAMP2 on intracellular mycobacterial load and clearance of extracellular residual mycobacteria were assessed by tuberculosis colony-forming unit counting. Flow cytometry was used to assess the total apoptosis rate. Real-time fluorescent quantitative PCR was conducted to determine the relative expression of LAMP2, apoptosis genes, pyroptosis genes, and autophagy genes. Western blot analysis was performed to measure the relative expression of LAMP2 proteins, apoptosis proteins, pyroptosis proteins, and autophagy proteins. Results Dual luciferase reporter assay test showed that there was a targeting relationship between LAMP2 and miR-207. The transfection model was successfully constructed under real-time fluorescent quantitative PCR and Western blot statistical analysis, and microscopic observation. The infection model was successfully established under microscopic observation. Colony forming unit counting revealed that the number of colonies in the OP-LAMP2 group was lower than that in the EP group, while the number of colonies in the siLAMP2 group was higher than that in the siLAMP2-NC group. Flow cytometry assay revealed that the total apoptosis in OP-LAMP2 group was lower than that in EP group, and the total apoptosis in siLAMP2 group was higher than that in siLAMP2-NC group. Real-time fluorescence quantitative PCR and Western blot analysis revealed that the relative expression of apoptosis and pyroptosis-related proteins and genes in the control group was lower in the OP-LAMP2 group compared to the EP group, and higher in the siLAMP2 group compared to the siLAMP2-NC group. Real-time fluorescence quantitative PCR detected that the relative expression of autophagy positively regulated genes Microtubule-associated protein 1 light chain 3(LC3)and Beclin1 in the OP-LAMP2 group was higher in the OP-LAMP2 group compared to the EP group, and lower in the siLAMP2 group compared to the siLAMP2-NC group, while the relative expression of negatively regulated autophagy genes followed the opposite trend to that of autophagy positively regulated genes. The relative expression of autophagy-related proteins was consistent with the trend of autophagy genes. Conclusions miR-207 enhances macrophage apoptosis, cellular pyroptosis and inhibits autophagy, promoting survival of Mycobacterium tuberculosis by targeting the autophagy-related protein LAMP2, thus offering a novel therapeutic direction for tuberculosis.

Purpose:
Radiation-induced dermatitis (RD) is a common side-effect of therapeutic ionizing radiation that can severely affect patient quality of life. This study aimed to develop a risk prediction model for the occurrence of RD in patients with cervical carcinoma undergoing chemoradiotherapy using electronic medical records (EMRs).
Methods:
Using EMRs, the clinical data of patients who underwent simultaneous radiotherapy and chemotherapy at a tertiary cancer hospital between 2017 and 2022 were retrospectively collected, and the patients were divided into two groups: a training group and a validation group. A predictive model was constructed to predict the development of RD in patients who underwent concurrent radiotherapy and chemotherapy for cervical cancer. Finally, the model's efficacy was validated using a receiver operating characteristic curve.
Results:
The incidence of radiation dermatitis was 89.5% (560/626) in the entire cohort, 88.6% (388/438) in the training group, and 91.5% (172/188) in the experimental group. The nomogram was established based on the following factors: age, the days between the beginning and conclusion of radiotherapy, the serum albumin after chemoradiotherapy, the use of single or multiple drugs for concurrent chemotherapy, and the total dose of afterloading radiotherapy. Internal and external verification indicated that the model had good discriminatory ability. Overall, the model achieved an area under the receiver operating characteristic curve of .66.
Conclusions
The risk of RD in patients with cervical carcinoma undergoing chemoradiotherapy is high. A risk prediction model can be developed for RD in cervical carcinoma patients undergoing chemoradiotherapy, based on over 5 years of EMR data from a tertiary cancer hospital.

Objective miR-207 is differentially expressed in many diseases.We investigated the mechanism by which miR-207 overexpression regulates the survival of Mycobacterium tuberculosis(H37Ra)in macrophages,to provide a theoretical basis for the targeted therapy of tuberculosis.Methods Macrophages were divided into four groups:blank(Ana-1 cells),control(cells infected with H37Ra),mi(infected with H37Ra and transfected with miRNA-207 mimics),and mi-NC(infected with H37Ra and transfected with NC mimics)groups.A model of tuberculosis infection was established using H37Ra-infected Ana-1 cells,and miRNA-207 and NC mimics were transfected into Ana-1 cells using the liposome transfection method.Tuberculosis colony-forming units were counted to assess the effect of miR-207 on intracellular mycobacterial load and clearance of extracellular residual mycobacteria.The total apoptosis rate was detected by flow cytometry.The relative expression levels of miR-207 and apoptosis,pyroptosis,inflammation,and autophagy genes were measured by quantitative real-time polymerase chain reaction(qPCR).Relative expression levels of apoptosis,pyroptosis,and autophagy proteins were detected by Western blot.Fluorescence microscopy and multifunctional enzyme labeling were used to detect the fluorescence intensity of intracellular reactive oxygen species(ROS)and lactate dehydrogenase(LDH).Results Successful establishment of the infection model was observed under the microscope.qPCR showed that miR-207 expression was lower in the control compared with the blank group(P<0.01),indicating differential expression between these two groups.miR-207 expression was significantly higher in the mi compared with the mi-NC group(P<0.0001),indicating successful establishment of the transfection model.The number of colonies and total apoptosis were both higher in the mi group compared with the mi-NC and control groups(P<0.001).qPCR and Western blot showed that the relative expression levels of apoptotic genes and proteins were higher in the control group than in the blank group(P<0.05),and higher in the mi group than in the mi-NC group(P<0.05).The relative expression levels of inflammatory genes were higher in the control than in the blank group(P<0.001).The relative expression levels of inflammatory genes were higher in the mi group than in the mi-NC group(P<0.05),and the relative expression levels of pyroptosis genes and proteins were higher in the control group compared with the blank group(P<0.01)and higher in the mi group compared with the mi-NC group(P<0.05).The relative expression levels of the autophagy positively-regulated genes LC3 and Beclin1 were higher in the control compared with the blank group(P<0.0001),and lower in the mi than in the mi-NC group(P<0.05),while negatively-regulated autophagy genes showed the opposite trend.Autophagy-related proteins showed similar trends to the autophagy genes.ROS fluorescence intensity was higher in the control compared with the blank group(P<0.05),and higher in the mi compared with the mi-NC group(P<0.001).LDH content was higher in the control than in the blank group(P<0.01),but there was no significant difference between the mi and mi-NC groups(P>0.05).Conclusions miR-207 overexpression promotes apoptosis,cellular pyroptosis,and inflammation,inhibits autophagy,and favors H37Ra survival.These result provide a potential new direction for the treatment of tuberculosis.
