Objective:To evaluate the efficacy of an etoposide (Vp16) -intensified conditioning regimen in allogeneic hematopoietic stem cell transplantation (allo-HSCT) for the treatment of relapsed/refractory acute myeloid leukemia (AML).Method:A retrospective analysis was conducted on the clinical data of 27 recipients with relapsed/refractory AML who underwent allo-HSCT using a Vp16-intensified conditioning regimen at Aerospace Center Hospital from January 2019 to January 2022. Transplantation-related complications and treatment outcomes were observed. Kaplan-Meier survival analysis was used to assess the overall survival (OS) and disease-free survival (DFS) rates.Result:Among the 27 recipients, there were 14 males and 13 females, with a median age of 41 years (range: 12~55 years). Except for one recipient who experienced primary graft failure, the remaining 26 recipients achieved hematopoietic reconstitution. The median neutrophil and platelet engraftment times were 13 days (range: 9~20 days) and 13.5 days (range: 11~33 days), respectively. Regimen-related toxicity (RRT) was mainly gastrointestinal toxicity and oral mucositis, and no deaths were attributed to RRT. A total of 12 recipients (44.44%) developed acute graft-versus-host disease (aGVHD), of whom 3 cases (11.11%) had grade III~IV aGVHD. Chronic GVHD (cGVHD) occurred in 13 recipients (48.15%), including 8 cases (29.63%) of extensive cGVHD. The median follow-up time after transplantation was 17 months (range: 1~48 months). Fifteen recipients (55.56%) survived without disease, while 12 recipients (44.44%) died— 9 due to relapse and 3 due to transplant-related complications. The 1-year overall survival and DFS rates were 74.07% and 59.26%, respectively; the 2-year overall survival and DFS rates were 59.26% and 55.56%, respectively. The 2-year relapse rate and transplant-related mortality (TRM) were 33.33% and 11.11%, respectively.Conclusion:The Vp16-intensified conditioning regimen in allo-HSCT appears to be a viable treatment option for patients with relapsed/refractory AML, offering favorable efficacy and manageable safety.

This paper analyzed the causes of peripheral nerve injury induced by acupoint injection, and proposed methods for prevention. These methods included emphasizing the physicochemical properties of medications and strengthening research on medication compatibility, classifying high-risk acupoints and establishing international standards for safe acupoint needling, standardizing clinical procedures for acupoint injection, and incorporating ultrasound technology when necessary to improve the accuracy and safety of the procedure. These strategies aimed to reduce the risk associated with the clinical application of acupoint injection.

Objective:To observe the effects of ointment and massage on inflammation, oxidative stress and angiogenesis after skeletal muscle trauma, and to explore their mechanisms.Methods:Forty-two adult male Sprague-Dawley rats were randomly divided into a blank group ( n=6), an ointment and massage (O&M) group ( n=18) and a model group ( n=18). The blunt contusion model of gastrocnemius malformation was established in both the O&M and model groups using self-made percussion instruments. Two hours after successful modeling, the anti-inflammatory pain-relieving cream was applied to the injured area, and massaged evenly and gently for 5 minutes. That was repeated with an interval of 12 hours. No treatment was given to the model and blank groups. On the 1st, 3rd and 7th days after modeling, injured gastrocnemius muscles were resected after collecting abdominal blood. Hematoxylin-eosin (HE) staining and immunofluorescent (CD34) staining were applied, and serum superoxide dismutase (SOD) and malondialdehyde (MDA) contents were detected. Results:HE staining showed that at each time point the gastrocnemius muscle fibers of the model group were significantly more swollen and deformed, collapsed and dissolved than those of the blank group, with a large number of inflamed cells. The O&M group had better recovery, with more newly-generated muscle cells, less inflammatory infiltration and more normal cell shapes than the model group. Fluorescence was stronger in the O&M and model groups than in the blank group at each time point, with that of the O&M group significantly stronger than in the model group. The average SOD and MDA levels in the model and O&M groups were significantly higher than in the blank group, and on the 1st and 3rd days the O&M group′s average SOD level was significantly higher than the model group′s average, though by the 7th day there was no significant difference. The average MDA content of the O&M group was significantly lower than the model group′s average at each time point.Conclusion:Ointment and massage can effectively reduce the local inflammatory response and oxidative stress after a skeletal muscle injury. They can accelerate local angiogenesis, promoting the repair of damaged tissues.

Objective:To observe the therapeutic effect of vibrating the abdomen on anorexia model rats,as well as its effects on cholecystokinin octapeptide(CCK-8)and motilin(MTL)in the peripheral blood. Methods:Forty young rats were randomly divided into a normal group(n=10)and a modeling group(n=30).Rats in the normal group were fed common feed.The anorexia model was established by the etiological simulation method in the modeling group,and these rats were further randomly divided into a drug group,a vibrating abdomen group,and a model group 3 weeks after the anorexia model was induced,with 10 rats in each group.The drug group was given Jian Wei Xiao Shi Pian by intragastric administration at a dose of 0.72 g/(kg·bw)(0.72 g drug was dissolved in 10 mL purified water).The normal group and the model group were given purified water once a day in the morning.The vibrating abdomen group was treated with vibrating the abdomen once a day for 21 times.The body mass,food intake,serum CCK-8,MTL,gastrin(GAS),neurotensin(NT)levels,and the intestinal propulsion rate of rats in each group were measured. Results:Compared with the model group,the body mass,food intake,serum MTL and GAS levels,and the small intestine propulsion rate increased significantly,and the serum CCK-8 and NT levels,the gastric residual rate decreased significantly in the vibrating abdomen group and the drug group(P<0.05).There were no significant differences between the vibrating abdomen group and the drug group(P>0.05). Conclusion:Vibrating the abdomen increases the food intake and body mass of anorexia model rats,reduces the residue of gastric contents,improves the small intestine propulsion rate,and therefore has a good therapeutic effect on anorexia.The mechanism may be related to inhibiting the secretion of CCK-8 and NT in plasma and promoting the release of MTL and GAS in serum.

Objective To investigate the current status of nurses'knowledge,attitude and practice regarding sleep management of critically ill children in pediatric ICU,and to analyze its impact factors.Methods A self-designed questionnaire on general information and a questionnaire on knowledge and practical behaviors of pediatric ICU nurses on child's sleep management were used.In March 2023,902 pediatric ICU nurses from 24 hospitals in China were surveyed using a convenient sampling method,and the impact factors were analyzed using multiple stepwise linear regression.Results 893 valid questionnaires were collected and the recovery rate of valid questionnaires was 99.00％.Nurses in pediatric ICU scored(33.71±7.76)in knowledge dimension,(37.38±4.86)in attitude dimension and(80.60±16.78)in practice dimension,with a total score of(151.78±24.27).The scores of knowledge and attitude,knowledge and practice,attitude and practice are all positively correlated(r=0.393,P＜0.001;r=0.495,P＜0.001;r=0.320,P＜0.001).The results of multiple stepwise linear regression analysis showed that gender,region,whether they had received sleep management training were the influencing factors of pediatric ICU nurses'total score of knowledge,attitude and practice towards children's sleep management(P＜0.05).Conclusion Nurses in pediatric ICU are positive about sleep management for critically ill children,but their knowledge and practice levels need to improve.Nursing managers should strengthen the theoretical knowledge and practical behavioral training of pediatric ICU nurses on child sleep management,develop scientific sleep management plans,and guide nurses to make reasonable evaluation and interventions to improve children's sleep quality.

Objective To develop an evidence-based,localized practice protocol for the interhospital transfer of critically ill children.Methods Through a comprehensive evidence summary and semi-structured interviews,a preliminary inter-hospital transfer practice protocol for critically ill children was formulated.A panel of 31 experts from 12 hospitals in China participated in 2 rounds of expert correspondence between May and July 2022,facilitating meticulous revision of the protocol entries.Results The response rate for both rounds of questionnaires was 100%,and the expert authority coefficients ranged from 0.926 to 0.931.In the second round of consultation,the coefficient of variation for the importance score of each entry ranged from 0.036 to 0.226,and the Kendall's W was determined to be 0.201(P＜0.001).Additionally,the coefficient of variation for the feasibility score of each entry fell within the range of 0.070 to 0.314,with Kendall's W of 0.124(P＜0.001).Ultimately,the final interhospital transfer protocol for critically ill children comprised 8 level Ⅰ entries,16 level Ⅱ entries,and 75 level Ⅲ entries.Conclusion The interhospital transfer protocol constructed in this study is grounded in scientific evidence and exhibits practical feasibility.It serves as a valuable reference for organizing and implementing interhospital transfers of critically ill children.

Objective: To observe the clinical efficacy of Tuina (Chinese therapeutic massage) plus oxiracetam in treating mild vascular dementia (VD) and seek its underlying mechanism. Methods: Ninety-six patients with mild VD were randomized into an observation group and a control group, with 47 cases in the observation group and 49 cases in the control group. The control group received oral oxiracetam capsules for treatment, and the observation group was given additional Tuina treatment. Before and after treatment, the mini-mental state examination (MMSE) was adopted to assess the patient's cognitive function; the activities of daily living (ADL) scale was used to evaluate their ability to conduct daily activities; changes in the serum inflammatory factors and oxidative stress indicators were also detected. Results: After treatment, the serum content of malondialdehyde (MDA) decreased in both groups (P<0.05) and was lower in the observation group than in the control group (P<0.05); the serum contents of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) increased in both groups (P<0.05) and were higher in the observation group than in the control group (P<0.05); the serum contents of interleukin (IL)-1, tumor necrosis factor (TNF)-α, IL-6, and IL-8 declined in both groups (P<0.05) and were lower in the observation group than in the control group (P<0.05). After the intervention, the levels of systolic velocity (Vs) and mean velocity (Vm) of the middle cerebral artery elevated, and the pulsatility index (PI) dropped in patients in the two groups, showing significant intra-group differences (P<0.05); the levels of Vs and Vm in the observation group were higher than those in the control group, and the PI was lower in the observation group than in the control group, showing significant between-group differences (P<0.05). The MMSE and ADL scores increased in both groups after the intervention (P<0.05) and were higher in the observation group than in the control group (P<0.05). Conclusion: In the treatment of mild VD, Tuina plus oxiracetam can improve the cerebral blood supply, ADL, and cognitive function; the mechanism may be associated with the reduction of oxidative stress damages and inflammatory reactions.
