Nonsteroidal anti-inflammatory drugs (NSAIDs) are clinically used with common gastrointestinal adverse reactions, among which NSAIDs-induced small intestinal injuries (NSIs) are manifested in the appearance of jejunum and ileal mucosa erythema, erosion, ulcer, hemorrhage, intestinal wall perforation and obstruction et al..The pathological mechanisms of NSIs are complex, with a lack of effective prevention or treatment methods.This review summarizes the research progress of the pathological mechanisms of NSIs as well as the prevention and treatment of NSIs by misoprostol, mucosal protective agents, antibiotics and probiotics, traditional Chinese medicines and their active ingredients, nutritional supplements and other drugs in the past five years, in order to provide reference and basis for the research and development of new NSIs drugs.

Objective:To develop an information system for testing radiological protection that can interface with National Radiation Health Information Platform/Medical Radiation Monitoring Subsystem and to improve the testing efficiency.Methods:Complying with the relevant national regulations and standards, the analysis was carried out of demand investigation and system modeling. An information system for testing radiological protection was established using B/S architecture, comprising three modules such as testing, audit and system management. The users at four levels were set of administrator, inspector, auditor and report issuer.Results:Based on test result, the developed information system has been shown to realize the informatization of the whole process from filling, auditing, issuing, issuing of the testing report to data uploading, with improved testing efficiency.Conclusions:The developed information system for testing radiological protection can improve the testing efficiency, and can be successfully interfaced with the National Radiation Health Information Platform/Medical Radiation Protection Monitoring Subsystem.

Objective To systematically evaluate the efficacy of traditional Chinese medicine(TCM)in the treatment of recurrent spontaneous abortion and their regulatory effects of levels of peripheral blood Th17 cells and Treg cells.Methods Computer retrieval of CNKI,WanFang,VIP,SinoMed,FMRS,PubMed,Cochrane Library,Embase,Web of science and other databases were carried out.RCTS related to the regulation of Th17 and Treg cells by TCM in the treatment of recurrent spontaneous abortion,published from the establishment of the database to June 2023 were screened.Two reviewers evaluated the quality of the literature according to the Cochrane handbook.RevMan5.4 software was used for Meta-Analysis.Results A total of 10 studies that involved 1 052 patients were included.The Meta-Analysis results showed that compared to the control group,the effective rate[RR=1.20,95%CI(1.11,1.30),P<0.000 01],live birth rate[RR=1.32,95%CI(1.16,1.50),P<0.000 01]and the reduction of adverse drug reactions[RR=0.34,95%CI(0.14,0.83),P=0.02]were significantly improved by the intervention of TCM.After treatment with TCM,the expression of Th17 cells was decreased[MD=-0.71,95%CI(-1.01,-0.41),P<0.000 01],and the expression of Treg cells was increased[SMD=1.21,95%CI(0.80,1.62),P<0.000 01].The ratio of Th17/Treg cells was decreased[SMD=-2.62,95%CI(-4.09,-1.14),P=0.000 5].Conclusion TCM used for post-pregnancy or before and after pregnancy can significantly improve the clinical symptoms and live birth rate of patients with recurrent spontaneous abortion,wihch showed high safety.Moreover,TCM can reduce the expression of Th17 cells,up-regulate the expression of Treg cells and regulate the immune balance of Th17/Treg cells,which is conducive to embryonic development after pregnancy.

Objective To establish a model for estimating the eye lens dose of the first operator in interventional therapy based on the Monte Carlo simulation, and to provide a scientific basis for the rapid and accurate evaluation of the eye lens dose for radiation workers in interventional therapy. Methods Based on the MIRD phantom and eye model for adult Chinese males, the MCNPX program was used to establish the physical model to calculate the spatial distribution of radiation field and eye lens dose for the first operator. A GR200 Type A LiF (Mg, Cu, P) thermoluminescence dosimeter was used for experimental measurement to verify the simulation results. Results Monte Carlo simulation and experimental measurements showed that the spatial distribution of radiation field was symmetrical. Compared with the measured doses, the errors of the simulated eye lens dose of the first operator were between −8.3% and 7.3%. The dose of the left eye lens was higher than that of the right eye. Conclusion The Monte Carlo model constructed in this study initially realizes the simulation of eye lens dose of the first operator in interventional therapy. In the future, the model will be further optimized based on irradiation parameters such as exposure time, tube voltage, tube current, and projection direction used in clinic practice, so as to more accurately evaluate the eye lens dose of interventional therapy staff.

The ticks feed large amount of blood from their hosts and transmit pathogens to the victims. The salivary gland plays an important role in the blood feeding. When the female ticks are near engorgement, the salivary gland gradually loses its functions and begins to rapidly degenerate. In this study, data-independent acquisition quantitative proteomics was used to study changes in the phosphorylation modification of proteins during salivary gland degeneration in Haemaphysalis longicornis. In this quantitative study, 400 phosphorylated proteins and 850 phosphorylation modification sites were identified. Trough RNA interference experiments, we found that among the proteins with changes in phosphorylation, apoptosis-promoting Hippo protein played a role in salivary gland degeneration.

Objective To investigate the safety, economic benefits and psychological effects of day breast conserving surgery for breast cancer. Methods The demographic data and clinical data of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgeries in West China Hospital of Sichuan University from March 2020 to June 2021 were retrospectively collected; the demographic data, clinical data, medical and related transportation costs, and preoperative and postoperative BREAST-Q scores of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgery in West China Hospital of Sichuan University from June 2021 to June 2022 were prospectively collected. The safety, economic benefit, and psychological satisfaction of day surgery was analyzed. Results A total of 42 women with breast cancer were included in the retrospective study and 39 women with breast cancer were included in the prospective study. In both prospective and retrospective studies, the mean age of patients in both groups were <50 years. There were only statistical differences between the two groups in the aspects of hypertension (P=0.022), neoadjuvant chemotherapy (P=0.037) and postoperative pathological estrogen receptor (P=0.033) in the prospective study. In postoperative complications, there were no statistical differences in the surgical-related complications or anesthesia-related complications between the two groups in either the prospective study or the retrospective study (P>0.05). In terms of the overall cost, we found that the day surgery group was more economical than the ward surgery group in the prospective study (P=0.002). There were no statistical differences in postoperative psychosocical well-being, sexual well-being, satisfaction with breasts or chest condition between the two groups (P>0.05). Conclusion It is safe and reliable to carry out breast conserving surgery in day surgery center under strict management standards, which can save medical costs and will not cause great psychological burden to patients.
