Objective To predict the radiation impact of discharging wastewater containing uranium within the specified limit generated during the normal operation of a new production line at a nuclear fuel plant on the receiving water body and its downstream, and to provide a reference for the management of radioactive liquid effluent discharge from nuclear facilities. Methods Based on the technical guidelines for environmental impact assessment, literature on radiation environmental impact assessment, and data collected from on-site investigations, appropriate hydrological parameters and prediction models were selected to analyze and predict the variation pattern of radioactive nuclide uranium along the receiving water body and the radiation exposure of nearby residents. Results The maximum increase in uranium concentration in the receiving water body and its downstream caused by the discharge of uranium-containing wastewater was 1.14 μg/L. The maximum predicted concentration was 2.75 μg/L after adding the background data of the water body. The resulting maximum individual annual effective dose for the public was 1.49 × 10−4 mSv/a. Conclusion The maximum predicted uranium concentration in the receiving water body and its downstream is lower than the uranium concentration limit of 30 μg/L specified in the Standards for Drinking Water Quality (GB 5749-2022). The maximum individual annual effective dose for the public is much lower than the control value of 0.2 mSv/a specified in the Radiation Protection Regulations for Uranium Processing and Fuel and Fuel Manufacturing Facilities (EJ 1056-2018). The radiation impact is acceptable.

Objective: To evaluate the feasibility and effectiveness of dual fluorescence laparoscopy in the localization of ureteral stricture and its blood supply,and to provide a new idea for the treatment of complex ureteral stenosis,thus helping doctors to improve the efficiency of ureteral reconstruction surgery. Methods: Our team developed a dual fluorescence laparoscopic system,which could simultaneously identify the ureter stricture by intra-ureteral injection of methylene blue (MB) and assess the blood supply of the ureteral stumps by intravenous injection of indocyanine green (ICG). Results: The clinical data of 3 patients who underwent lingual mucosa ureteroplasty using dual fluorescence laparoscopy in Zhongnan Hospital of Wuhan University were retrospectively analyzed.All operations were successful,without conversion to open surgery.The operation time was 144,132 and 163 minutes,respectively.The length of harvested lingual mucosa graft was 2.0,2.8 and 3.5 cm,respectively.No intraoperative or postoperative complications occurred.Eight weeks after operation,ureterography showed that the ureter was unobstructed. Conclusion: Dual fluorescence laparoscopy is safe and feasible in the repair of complex ureteral stricture with lingual mucosa graft,which provides a new idea for complex ureteral reconstruction.

AIM To explore the effects of Rosa roxburghii Radix on ulcerative colitis(UC)in rats based on pyroptosis and neutrophil extracellular traps(NETs).METHODS Rats were randomly divided into the normal group and the model group.The successfully established UC rat models by trinitrobenzene sulfonic acid(TNBS)/ethanol enema were then randomly divided into the model group,the sulfasalazine group(0.3 g/kg)and the low,medium and high dose R.roxburghii Radix groups(2,4,8 g/kg),followed by dosing of corresponding drugs by gavage.21 days later,the rats had their disease activity index(DAI)score calculated;their pathological changes of colon tissue observed by HE staining;their levels of serum interleukin(IL)-18,IL-1β and myeloperoxidase(MPO)detected by ELISA;and their protein expressions of NE,MPO,NLRP3,caspase-1 and GSDMD in colon tissue detected by Western blot and immunohistochemistry.RESULTS Compared with the normal group,the model group displayed increased DAI score(P<0.01),increased serum levels of IL-1β,IL-18 and MPO(P<0.01),and increased protein expressions of NE,MPO,caspase-1,NLRP3 and GSDMD in colon tissue(P<0.01).Compared with the model group,the groups intervened with sulfasalazine,or medium,or high dose R.roxburghii Radix demonstrated with decreased DAI scores(P<0.05,P<0.01),decreased serum levels of IL-1β,IL-18 and MPO(P<0.01),and decreased protein expressions of NE,MPO,caspase-1,NLRP3 and GSDMD in colon tissue(P<0.05,P<0.01).CONCLUSION R.roxburghii Radix may alleviate the inflammatory reaction in a rat model of UC and improve its pathological injury of colon via regulating pyroptosis and NETs.

Objective To observe the clinical efficacy of Shugan Tiaoshen Acupuncture in the treatment of mild-to-moderate perimenopausal depressive disorder(PDD).Methods A total of 66 patients with mild-to-moderate PDD were randomly divided into the observation group and the control group,with 33 cases in each group.The observation group was treated with Shugan Tiaoshen Acupuncture,and the control group was treated with conventional western medicine for 8 weeks.After 2 months of treatment,the clinical efficacy of the two groups was evaluated,and the changes in Hamilton Depression Scale(HAMD-17)scores before and after treatment,as well as the scores of Menopausal Quality of Life Scale(MENQOL)were observed in the two groups.The changes in serum luteinising hormone(LH),follicle-stimulating hormone(FSH)and oestradiol(E2)levels were compared before and after treatment between the two groups,and the safety and the occurrence of adverse reactions in the two groups were evaluated.Results(1)During the study,3 cases in the observation group and 2 cases in the control group were lost to followup.Finally,30 cases in the observation group and 31 cases in the control group were included in the efficacy statistics.(2)After treatment,the total score of HAMD-17 and the scores of each factor in the two groups were significantly improved(P<0.05),and the total score of HAMD-17 and the scores of anxiety/somatization factor and sleep factor in the observation group were significantly superior to those in the control group,the differences were statistically significant(P<0.05).(3)After treatment,the total score of MENQOL and the scores of vascular dimension,physiological dimension and sexual life dimension in the two groups were significantly improved(P<0.05),and the total score of HAMD-17 and the scores of vascular dimension and physiological dimension in the observation group were significantly superior to those in the control group,the differences were statistically significant(P<0.05).(4)After treatment,the levels of LH,FSH and E2 in the two groups were significantly improved(P<0.05),and the improvement of LH,FSH and E2 levels in the observation group was significantly superior to that in the control group(P<0.05).(5)The total effective rate was 93.33%(28/30)in the observation group and 74.19%(23/31)in the control group.The curative effect of the observation group was superior to that of the control group,and the difference was statistically significant(P>0.05).Conclusion Shugan Tiaoshen Acupuncture in the treatment of mild-to-moderate PDD can significantly improve the clinical symptoms of patients,improve the quality of life of patients,regulate the level of sex hormones,and have a significant effect.

The widespread application of implantable materials has brought about a corresponding increase in implant-related complications, with implant-associated infections being the most critical. Biofilms, which often form on these implants, can significantly impede the effectiveness of traditional antibiotic therapies. Therefore, strategies such as surgical removal of infected implants and prolonged antibiotic treatment have been acknowledged as effective measures to eradicate these infections. However,the challenges of antibiotic resistance and biofilm persistence often result in recurrent or hard-to-control infections, posing severe health threats to patients. Recent studies suggest that phages, a type of virus, can directly eliminate pathogenic bacteria and degrade biofilms. Furthermore, clinical trials have demonstrated promising therapeutic results with the combined use of phages and antibiotics. Consequently, this innovative therapy holds significant potential as an effective solution for managing implant-associated infections. This paper rigorously investigates and evaluates the potential value of phage therapy in addressing orthopedic implant-associated infections, based on a comprehensive review of relevant scientific literature.
