ObjectiveTo explore the effect of elbow-wrist functional orthosis on plantar pressure distribution and balance function in stroke patients with hemiplegia. MethodsFrom June, 2024 to April, 2025, 60 patients with post-stroke hemiplegia were recruited from Huashan Hospital, Fudan University, and Shanghai Hebin Rehabilitation Hospital. They were randomly divided into control group (n = 30) and intervention group (n = 30). The control group received routine neurological rehabilitation, while the intervention group received additional training with an elbow-wrist functional orthosis on the affected side, for eight weeks. Before and after intervention, the Modified Ashworth Scale (MAS) of the elbow joint, plantar pressure symmetry index (SI), plantar contact area and mean plantar pressure were recorded, and balance and mobility were assessed using the Berg Balance Scale (BBS), Timed Up & Go Test (TUGT) and 10-Meter Walk Test (10MWT). ResultsTwo cases dropped out in the control group. After treatment, MAS grades of the elbow joint, forefoot SI, affected side plantar pressure area, BBS scores, TUGT and 10MWT of both groups improved (|Z| > 3.969, |t| > 3.528, P < 0.01), while the hindfoot SI and average pressure of the affected foot improved in the intervention group (∣t∣ > 4.264, P < 0.001). Except for TUGT and 10MWT, the intervention group was superior to the control group (∣Z∣ > 2.030, ∣t∣ > 2.096, P < 0.05). ConclusionThe elbow-wrist functional orthosis can enhance balance function in stroke patients with hemiplegia by reducing upper-limb spasticity, optimizing center-of-gravity distribution, and improving postural control.

Objective To explore the effect of hyperbaric oxygen combined with synchronous brain bionic electrical stimulation on patients with stroke-related sleep disorders.Methods From November,2023 to November,2024,a total of 68 stroke patients with stroke-related sleep disorders ad-mitted to Huashan Hospital,Fudan University were selected.They were randomly divided into control group(n=34)and experimental group(n=34).The control group received routine hyperbaric oxygen therapy,while the ex-perimental group received routine hyperbaric oxygen therapy combined with synchronous brain bionic electrical stimulation inside the chamber,for four weeks.Pittsburgh Sleep Quality Index(PSQI),sleep-monitoring wrist-bands,Self-rating Anxiety Scale(SAS)and Self-rating Depression Scale(SDS)were used to assess the outcomes before and after treatment..Results Four patients in the control group and one in the experimental group dropped out.After treatment,the scores of each factors of PSQI decreased in both groups(t>2.693,P<0.05),and were lower in the experimental group than in the control group(t>2.699,P<0.01),expect hypnotic drug use(P>0.05);the total sleep time,deep sleep time and rapid eye movement sleep time became longer in both groups(|t|>7.270,P<0.001),and they were longer in the experimental group than in the control group(|t|>5.712,P<0.001);the scores of SAS and SDS decreased in both groups(t>9.530,P<0.001),and they were less in the experimental group than in the control group(t>4.740,P<0.001).Conclusion Synchronous brain bionic electrical stimulation in hyperbaric oxygen chamber could effectively prolong the total sleep time,deep sleep time and rapid eye movement time of patients with stroke-related sleep disorders,re-lieve anxiety and depression after stroke,and improve sleep quality.

Objective: To investigate the symptoms of depression and anxiety and their influencing factors in adolescents undergoing facial scar plasty, so as to provide insights into psychological interventions among them. Methods: The patients with facial scars who were 14 to 25 years old and admitted to the Department of Plastic Surgery, Hospital of Dermatology Chinese Academy of Medical Sciences and Peking Union Medical College were selected. General information and scar condition were collected through questionnaire surveys. Symptoms of depression and anxiety were assessed using the Self-rating Depression Scale (SDS) and Self-rating Anxiety Scale (SAS). The patients who scored 50 points and over in both SDS and SAS were identified as having depression and anxiety symptoms. Factors affecting depression and anxiety symptoms were identified using a multivariable logistic regression model. Results: A total of 108 adolescents undergoing facial scar plasty were surveyed, with a mean age of (19.16±2.03) years. There were 50 boys (46.30%) and 58 girls (53.70%). Depression and anxiety symptoms were detected in 62 cases, accounting for 57.41%. Multivariable logistic regression analysis showed that girls (OR=1.547, 95%CI: 1.072-2.231), unhealthy diet (OR=1.428, 95%CI: 1.120-1.820), high scores of pain (OR=1.677, 95%CI: 1.120-2.511) and high scores of scar severity (OR=1.629, 95%CI: 1.112-2.387) were associated with increased risks of depression and anxiety symptoms in adolescents undergoing facial scar plasty, while high scores of social support (OR=0.569, 95%CI: 0.348-0.931) and high scores of resilience (OR=0.465, 95%CI: 0.252-0.858) were associated with decreased risks. Conclusion Depression and anxiety symptoms are relatively prevalent in adolescents undergoing facial scar plasty, and are influenced by gender, diet, pain degree, scar severity, social support and resilience.

Objective To explore the effect of multi-sensory artificial intelligence feedback gait training on the recovery of walking function in stroke patients based on enriched environment theory. Methods From July,2021 to June,2023,a total of 80 stroke patients in Huashan Hospital Affiliated to Fudan University were randomly divided into control group(n=40)and experimental group(n=40).Both groups received rou-tine rehabilitation in the lying and seated positions,for 40 minutes.The control group received ground walking training,for 20 minutes,while the experimental group received multi-sensory feedback gait training in enriched environment,for 20 minutes.Before and after four weeks intervention,the digital motion monitoring treadmill was used to mearsure step speed,step length,hip and knee swing angle and weight symmetry.They were as-sessed with Berg Balance scale(BBS),Fugl-Meyer Assessment-Lower Extremities(FMA-LE)and Barthel Index(BI). Results After intervention,the hip swing angle,step length of both sides and step speed significantly improved in both groups(|t|＞3.162,P＜0.05),and they were better in the experimental group than in the control group(|t|＞2.568,P＜0.05);the average knee joint swing angle and bilateral weight-bearing symmetry significantly im-proved in the experimental group(|t|＞3.249,P＜0.01);the scores of BBS,FMA-LE and BI improved in both groups(|t|＞3.569,P＜0.01),and they were better in the experimental group than in the control group(|t|＞2.922,P＜0.05). Conclusion Multi-sensory feedback gait training based on enriched environment theory could effectively improve the walking and balance of stroke patients,and increase the ability of independence.

Objective:To study the effects of plan-do-check-action (PDCA) cycle in quality improvement of neonatal resuscitation.Methods:From 2016 to 2020, the clinical data of neonates born in our hospital were analyzed. Neonates born during 2016 to 2017 were pre-PDCA group and neonates born during 2018 to 2020 were post-PDCA group. PDCA quality improvement included step-by-step, high-frequency and low-dose training, strengthening teamwork and adding equipment.Results:A total of 7 728 live-birth neonates were delivered before PDCA with 319 cases (4.1%) of asphyxia. 10 174 live-birth neonates were delivered after PDCA with 422 cases (4.1%) of asphyxia. The asphyxia rates showed no significant difference between the two groups ( P>0.05). The incidences of severe asphyxia before and after PDCA were both 0.8% without significant difference ( P>0.05). The success rates of resuscitation for severe asphyxia before and after PDCA was 27.9% and 44.9%, respectively, and the differences were statistically significant ( P<0.05). The mortality rates within 7 d before and after PDCA were 0.5‰ and 0.1‰ respectively, without significant differences ( P>0.05). Conclusions:The implementation of PDCA cycle and step-by-step, high-frequency, low-dose neonatal resuscitation training can effectively improve the success rate of resuscitation in newborns with severe asphyxia.

OBJECTIVETo generate mice which are specific for peroxisomproliferator-activated receptor-γ coactivator-1(PGC-1α) knockout in the GABAergic interneuron.

METHODSConditional mice specific for PGC-1αwere introduced from the Jackson Laboratory, USA and initially inbred to obtain homozygote PGC-1αmice. The PGC-1αconditional mice were further crossed with Dlx5/6-Cre-IRES-EGFP transgenic mice to achieve specific knockout of PGC-1α in the GABAergic interneuron.

RESULTSThe offspring with specific knockout PGC-1α gene were successful for the generation of GABAergic interneuron, with the resulting genotype being PGC-1α.

CONCLUSIONThe PGC-1αmice were obtained through a proper crossing strategy, which has provided a suitable platform for studying the function of PGC-1α in neuropsychiatric diseases.
