BACKGROUND:As the incidence of spinal cord injury increases with the years and axon regeneration after spinal cord injury was very difficult.How to promote the recovery from spinal cord injury and improve the transplantation efficiency of stem cells and other therapeutic cells after spinal cord injury has been the focus of clinical and scientific research. OBJECTIVE:To establish the efficient transplantation and replacement of mouse spinal cord microglia in the spinal cord injury model. METHODS:CX3CR1 creER-/+::LSL-BDNF-/+-tdTomato mice,CX3CR1+/GFP mice,β-actin GFP mice and C57 BL/6J wild-type mice at 8-10 weeks of age were selected.According to the requirements of the experiment,they were randomly divided into six groups.(1)Sham operation group:eight C57 BL/6J wild-type mice were used when only the lamina was removed without injury.(2)Spinal cord contusion injury group:eight C57 BL/6J wild-type mice were used.(3)Spinal cord crush injury group:eight C57 BL/6J wild-type mice were used.(4)Conjoined symbiotic spinal cord strike injury group:β-actin GFP mice with green fluorescent blood were surgically stitched together with C57 BL/6J wild-type mice,using eight β-actin GFP mice and eight C57 BL/6J wild-type mice.(5)Mr BMT-X Ray group(using PLX5622 to eliminate the spinal microglia and bone marrow transplantation with X-ray radiation):Bone marrow cells from four CX3CR1 creER-/+::LSL-BDNF-/+-tdTomato mice were extracted and transplanted into eight C57 BL/6J wild-type mice for spinal cord injury modeling.(6)Mr BMT-Busulfan group(using PLX5622 to eliminate the spinal microglia and bone marrow transplantation with Busulfan):Bone marrow cells from four CX3CR1+/GFP mice were transplanted into eight C57 BL/6J wild-type mice.The percentage of cell transplantation replacement in this group was observed,and the spinal cord injury model was not established in this group.The sham operation group,spinal cord contusion injury group and spinal cord crush injury group were sampled by perfusion on day 14 after spinal cord injury.The conjoined symbiotic spinal cord strike injury group was sampled by perfusion on day 7 after spinal cord injury.Mr BMT-X Ray group was sampled by perfusion on day 28 after spinal cord injury.Mr BMT-Busulfan group was sampled by perfusion on day 28 after transplantation.The sampling site was a 1.2 cm long spinal cord with the T10 segment as the center.In the Mr BMT-X Ray group and Mr BMT-Busulfan group,additional mouse brain tissue was retained to see if it would lead to brain transplantation and replacement.The number and proportion of transplanted and replaced cells in the damaged area were measured using transgenic mice,symbiosis and immunofluorescence. RESULTS AND CONCLUSION:Compared with the traditional peripheral blood transplantation(9.8%)of mice in the conjoined symbiotic spinal cord strike injury group,the new transplantation methods,Mr BMT-X Ray and Mr BMT-Busulfan,could greatly improve the proportion of spinal microglia transplantation and replacement,which could reach 84.8%and 95.6%,respectively.The difference was significant(P<0.05).The results showed that Mr BMT-X Ray and Mr BMT-Busulfan could achieve efficient replacement of spinal microglia cells,and could improve the problems of low cell transplantation efficiency,few survival numbers and unclear differentiation of the traditional cell transplantation methods.In addition,Mr BMT-X Ray can only replace the microglia in the spinal cord,while Mr BMT-Busulfan could avoid brain inflammation and injury caused by X-ray radiation transplantation.

Objective:To explore the clinical application value of magnetic stimulation combined with biofeed-back technology in female stress urinary incontinence(SUI).Methods:Sixty mild or moderate female SUI patients who underwent rehabilitation treatment at the Pelvic Floor Rehabilitation Center of Nanjing Women and Children's Healthcare Hospital from July to December 2021 were collected and randomly divided into two groups,with 30 pa-tients in each group.The observation group received a treatment protocol of electrical stimulation+biofeedback therapy(electric combined group)and the other group received a treatment protocol of magnetic stimulation+bi-ofeedback therapy(magnetic combined group).The treatment course for both groups consisted of 12 sessions.The Sandvik severity Index(urinary incontinence),the amount of u 1-hoururine leakage,pelvic floor muscle strength,pelvic floor muscle electrophysiological indices,the degree of urinary incontinence impact(ⅡQ-7 score)and the treatment efficacy were assessed and compared before and after the treatment in the two groups.Re-sults:Compared with the pre-treatment,the Sandvik Severity Index,the 1-hour urine leakage,and the n Q-7 score decreased in the magnetic combined group and the electric combined group after treatment,while the mus-cle strength of type Ⅰ,type Ⅱ,maximum of fast muscle,and mean value of slow muscle increased significantly,and the differences were statistically significant(P＜0.05).The difference between the above indexes was not statistically significant when comparing the magnetic combined group and the electric combined group after treat-ment(P＞0.05),and the treatment efficiency of the electric combined group was 93.33％and that of the magnet-ic combined group was 96.67％,and there was no statistical significance when comparing the efficiency of the two groups(P＞0.05).Conclusions:Magnetic stimulation combined with biofeedback technology has high thera-peutic efficiency for mild or moderate SUl,and is an optional rehabilitation technique for women with SUI.

Objective:To review the application of virtual reality in cardiac rehabilitation patients, identify intervention types, intervention elements, outcome indicators, and application effects.Methods:Electronic retrieval was implemented on PubMed, Web of Science, Embase, Cochrane Library, CINAHL, China National Knowledge Infrastructure, WanFang Data, and China Biology Medicine disc, using the Joanna Briggs Institute (JBI) scoping review guideline as the methodological framework. The search period was from the establishment of the database to April 10, 2023. The literature was extracted, summarized, and analyzed.Results:A total of 16 articles were included. The main types of virtual reality interventions were immersive and non-immersive. The intervention population included patients at different stages of cardiac rehabilitation, with unrestricted intervention venues. The intervention frequency was mostly 2 to 3 times per week, with intervention duration mostly ranging from 30 to 60 minutes and intervention cycles mostly ranging from 3 weeks to 12 months. Virtual reality improved the physical function and mental health of cardiac rehabilitation patients to a certain extent, and patient feedback showed good participation and satisfaction.Conclusions:Virtual reality has a positive impact on cardiac rehabilitation patients, with good safety and feasibility, but the recovery of cardiac function is still controversial. It is still necessary to conduct large sample size, multi center research, and track long-term effects.
