OBJECTIVE To evaluate the effect of bundled property management under multidisciplinary coopera-tion mode on prevention and control of multidrug-resistant organisms(MDROs)in intensive care units(ICUs)and explore the evidence-based methods for prevention and control of MDROs.METHODS A control study before and after the same time period was designed,the post-intervention period was 2024 when the bundled measures were fully implemented,and the pre-intervention period was 2023.Totally 8 ICUs of general and special depart-ments of a three-A hospital in Hubei Province were recruited as research subjects,the multidisciplinary coopera-tion team was established,the bundled management measures were introduced to optimize the quality of property cleaning work.The quality of service of the property cleaning work was evaluated through surveillance of hospital-associated infections and environmental hygiene surveillance before and after the bundled measures were imple-mented.RESULTS The isolation rate of MDROs from object surfaces of ICU environment declined from 0.34％to 0.10％after the bundled management measures under multidisciplinary cooperation model were implemented(P＜0.05).The incidence of MDROs hospital-associated infections was reduced from 0.07％to 0.03％(P＜0.05);the isolation rate of MDROs from patients decreased from 14.68％to 12.69％(P＜0.05);the performance as-sessment score of the cleaning staff was raised from(85.56±7.21)points to(91.06±3.07)points,however,there was no significant difference.The hand hygiene compliance rate of the cleaning staff was raised from 42.86％to 68.52％(P＜0.05).The positive rate of random ATP fluorescent test for environmental object surfaces de-clined from 25.41％to 10.05％(P＜0.05).Other environmental hygiene indexes for the cleaning and disinfection effects were improved in varying degrees.CONCLUSION The bundled management measures under multidiscipli-nary cooperation mode boost the property service quality,enhance the cleaning staff's awareness of disinfection,prevention and control,reduce the isolation rate of MDROs in environment,and thus decrease the incidence of MDROs hospital-associated infections and prevent the transmission.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective To evaluate the molluscicidal effect of spraying 5% niclosamide ethanolamine salt granules with drones against of Oncomelania hupensis snails in snail habitats in marshland areas. Methods From September to October, 2022, marshlands were sampled from Dantu District, Zhenjiang City, Jiangsu Province as study areas, and assigned into four groups, of approximately 3 000 m² per group. In Group A, environmental cleaning was performed, followed by spraying 5% niclosamide ethanolamine salt granules with knapsack sprayers at a dose of 40 g/m², and in Group B, 5% niclosamide ethanolamine salt granules were sprayed with knapsack sprayers at a dose of 40 g/m² without environmental cleaning, while in Group C, environmental cleaning was conducted, followed by spraying 5% niclosamide ethanolamine salt granules with drones at a dose of 40 g/m², and in Group D, 5% niclosamide ethanolamine salt granules were sprayed with drones at a dose of 40 g/m² without environmental cleaning. Then, the study areas in each group were equally divided into six blocks, with Block 1 for baseline surveys and blocks 2 to 6 for snail surveys 1, 3, 5, 7, 14 days following chemical treatment. The mortality of snails and the reduction of the density of living snails were calculated. Results A total of 132 frames were surveyed during the period from September to October 2022, and the occurrence of frames with living snails and means density of living snails were 61.36% (81/132) and 1.58 snails/0.1 m², respectively. The overall mortality rates of snails were 43.02% (77/179), 38.69% (77/199), 47.78% (86/180) and 31.02% (58/187) 14 days following chemical treatment in groups A, B, C and D, respectively (χ² = 11.646, P < 0.05), and there were differences detected in the snail mortality between group A and D, and between groups C and D (both P_adjusted values < 0.05). The adjusted mortality rates of snails were 37.42%, 36.07%, 38.85% and 40.40% in groups A, B, C and D 14 days post-treatment, and the density of living snails decreased by 48.10%, 63.29%, 67.09% and 69.62% 14 days post-treatment relative to pre-treatment, respectively. Conclusions Chemical treatment with drones is feasible for O. hupensis snail control in marshland areas; however, the molluscicidal effect of spraying 5% niclosamide ethanolamine salt granules with drones is comparable to spraying chemicals manually in marshland areas regardless of environmental cleaning.

Objective:To investigate the oral health knowledge awareness, attitude and behavior of children in endemic fluorosis areas of Guizhou Province, and evaluate the effectiveness of health education, so as to provide a scientific basis for improving oral health.Methods:In September 2020, 6 counties (cities and districts) were selected as survey sites from the historical fluorosis medium and severe areas in Guizhou Province.

BACKGROUND:Bone marrow mesenchymal stem cel s can repair intestinal ischemia-reperfusion injuny by interfering inflammatory reactions after intestinal ischemia-reperfusion to protect intestinal barrier functions. In recent years, umbilical cord blood mesenchymal stem cel s are gradual y used as a substitute source of bone marrow mesenchymal stem cel s. OBJECTIVE:To investigate the effects of umbilical cord blood mesenchymal stem cel s on acute intestinal ischemia-reperfusion injury. METHODS:Umbilical cord blood mesenchymal stem cel s were induced, isolated in vitro and tracked by CM-DiI fluorescent labeling. Sixty-three Sprague-Dawley rats were equivalently randomized into three groups:control group received normal saline enema, intestinal ischemia-reperfusion injury group with ethanol diluted trinitro-benzene-sulfonic acid and transplantation group administrated with 1×1010/L umbilical cord blood mesenchymal stem cel suspension via the tail vein at 1 hour after trinitro-benzene-sulfonic acid modeling. At 3 days after transplantation, colon tissues were removed in each group to observe pathological changes of the intestinal tract by hematoxylin-eosin staining. Besides, expression of leptin mRNA in the colon tissues and cyclooxygenase-2 in the mucosa were detected by RT-PCR and immunohistochemistry method, respectively. RESULTS AND CONCLUSION:Transplanted umbilical cord blood mesenchymal stem cel s distributed in the intestinal lymphoid tissue and among glandular epithelial cel s, suggesting that these stem cel s might be involved in the process of intestinal ischemia-reperfusion injury repair. Compared with the control group, intestinal injury in the injury group was significantly aggravated, and most intestinal epithelial cel s shed;and the transplantation group appeared to have significantly reduced intestinal damage and significantly less cel shedding. Expression of leptin mRNA was significantly higher in the injury group than the transplantation group fol owed by the control group, and there were significant differences among the three groups (P<0.05). Additional y, expression of cyclooxygenase-2 in the injury group was significantly higher than that in the control group (P<0.05);compared with the injury group, expression of cyclooxygenase-2 was significantly lower in the transplantation group (P<0.05). To conclude, leptin and cyclooxygenase-2 may be involved in acute intestinal ischemia-reperfusion injury, and umbilical cord blood mesenchymal stem cel transplantation significantly lessens intestinal ischemia-reperfusion injury, which provides an experimental basis for human treating acute intestinal ischemic injury.
