Objective To investigate the impact of virtual reality combined with body weight-supported treadmill training on phantom limb pain,lower limb dynamics,gait stability,balance func-tion,and quality of life in amputees.Methods A prospective study enrolled 100 unilateral lower limb amputees as participants,who were randomly divided into experimental group(n=50)and con-trol group(n=50).The experimental group received virtual reality combined with body weight-sup-ported treadmill training,while the control group received conventional rehabilitation training.Out-comes,including phantom limb pain intensity[Visual Analogue Scale(VAS),Douleur Neuropathique 4 Questions(DN4)scores],lower limb dynamics[vertical ground reaction force(Fz),anteroposterior ground reaction force(Fy),joint moments],gait parameters,static balance(Berg Balance Scale score),dynamic balance(stability time,proportion of gait support time),quality of life[12-Item Short-form Health Survey(SF-12)score],and activities of daily living[Modified Barthel Index(MBI)score]were assessed before intervention and at 4,8,and 12 weeks post-intervention.Results At 4,8,and 12 weeks post-intervention,the experimental group exhibited significantly lower VAS and DN4 scores compared to baseline and the control group(P＜0.05).Gait speed,stride length,ca-dence,stance time,Berg Balance Scale score,stability time,and proportion of gait support time improved in the experimental group compared to baseline and the control group(P＜0.05).SF-12 score,MBI score,peak Fz,peak Fy,knee flexion moment,ankle abduction moment,and stance phase proportion also increased significantly in the experimental group compared to baseline and the control group(P＜0.05).Conclusion Virtual reality combined with body weight-supported tread-mill training effectively alleviates phantom limb pain,improves lower limb dynamics,gait stability,and balance function,and enhances quality of life in amputees.

Objective Focusing on the problems of unbalanced nursing education resources and insufficient training,it discusses the path of nursing echelon training and nursing education resources optimization in secondary hospitals.Methods Based on nursing questionnaire,interview data and platform logs from 4 secondary hospitals in Hainan Province,Latent Dirichlet Allocation topic modeling,sentiment analysis and Social Network Analysis were used.Identify the core problems of educational resources and training system and propose optimization schemes.Results Topic modeling revealed that insufficient educational resources and information silos were major obstacles to shared platform development.Similarity analysis result showed high consistency in feedback regarding disconnected training content and single training models.Sentiment analysis result indicated that 50％of negative feedback focused on inadequate evaluation and incentive mechanisms.Social Network Analysis validated the significant role of multi-node collaboration in optimizing resource flows.Conclusion Building shared platforms,implementing differentiated training systems,and developing localized nursing faculty are critical pathways to achieving homogenized nursing education,providing valuable references for optimizing regional nursing education.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

OBJECTIVE:To optimize the extraction technology of chlorogenic acid in Prunus armeniaca flos,and compare the contents in P. armeniaca flos from different origins and varieties. METHODS:HPLC was conducted to determine the content of chlorogenic acid in P. armeniaca flos;using the volume fraction of ethanol,the ratio of material to liquid,ultrasonic extraction times and time as factor,the content of chlorogenic acid as index,single factor and orthogonal test were designed to optimize the extraction technology,and verification tests were carried out. The optimized extraction technology was used to extract and compare the contents of chlorogenic acid in Armeniaca sibirica from 7 origins of P. armeniaca flos and 3 origins of Armeniaca sibirica flos. RESULTS:The optimized extraction technology was extracting twice with 12-fold 75% ethanol,30 min each time. Under the con-ditions,the content of chlorogenic acid can reach 77.38 mg/g(RSD=0.58%,n=3);the contents of chlorogenic acid in A. sibiri-ca flos and P. armeniaca flos were 77.38-83.33 mg/g and 63.12-70.22 mg/g,respectively. CONCLUSIONS:The established extrac-tion technology is reasonable,stable and feasible. The contents of chlorogenic acid in A. sibirica are higher than that in P. armenia-ca flos;the contents have no obvious differences in the same variety of A. sibirica from different origins.

Objective To investigate the effects of rehabilitation nursing on quality of life in patients after burn injuries. Methods The re-ports about rehabilitation nursing for burn patients from January, 2004 to June, 2015 were searched and extracted from the databases of Chi-na Biology Medicine, China National Knowledge Infrastructure, Wangfang Data and Chongqing VIP Database, and analyzed with Review Manager 5.3. Results 11 non-randomized control studies (MINROS score:13~19) were eligible for meta-analysis. There were significant differences in the general health (MD=7.78, 95%CI:6.79~8.77, P<0.001), social function (MD=10.26, 95%CI:5.91~14.60, P<0.001), men-tal function (MD=9.71, 95%CI:6.87~12.55, P<0.001) and physical function (MD=6.88, 95%CI:3.95~9.81, P<0.001) between experimental group and control group. Conclusion Rehabilitation nursing can improve the quality of life of burn patients.

OBJECTIVETo investigate the influence of non-diabetic hyperglycemia on postoperative complications following laparoscopic colorectal cancer resection.

METHODSClinical data of 636 patients undergoing laparoscopic colorectal cancer resection in The Affiliated Nanhai Hospital of Southern Medical University between 2009 and 2013 were analyzed retrospectively. After excluding cases with diabetes mellitus, the patients were divided into the hyperglycemia group (blood glucose level>7.8 mmol/L at any time during hospitalization period, n=161) and the non-hyperglycemia group (n=309).

RESULTSCompared to non-hyperglycemia group, hyperglycemia group had more intraoperative blood loss [(186±80) ml vs. (158±74) ml, P=0.007] and longer postoperative hospital stay [(14.0±6.8) d vs. (11.2±5.5) d, P=0.013]. The overall rate of postoperative complication was 24.8% and 16.5% respectively (P=0.030), in the hyperglycemia and the non-hyperglycemia groups, and the mortality was 1.2% and 0.6% respectively (P=0.541). Multivariable analysis showed hyperglycemia was an independent risk factor of postoperative complication (RR=2.425, 95% CI:1.210-4.226, P=0.006).

CONCLUSIONSNon-diabetic hyperglycemia may increase the risk of postoperative complications following laparoscopic colorectal cancer resection. Perioperative blood glucose monitoring should be performed, regardless of patients with or without diabetes.
