Objective:To study the influence of electromyographic biofeedback therapy(EMGBFT)combined with mirror therapy(MT)on lower limb motor and balance function in stroke patients. Method:Sixty patients with hemiplegia after stroke were randomly divided into two groups:MT based EMG-BFT group and EMGBFT group,30 patients in each group.On the basis of conventional rehabilitation,the patients in the EMGBFT group received sham MT stimulation combined with EMGBFT,and the patients in the MT based EMGBFT group received MT combined with EMGBFT.Before and after treatment,the lower limb motor function of the patients was evaluated using Fugl-Meyer assessment scale-lower extremity(FMA-LE)and surface electromyography-integrated electromyography(iEMG)of knee flexion and ankle dorsiflex-ion,co-contraction ratio(CR).Plantar pressure-symmetry index(SI)of mean pressure and contact area of both feet,elliptical area of body center of gravity,anteroposterior(AP)and mediolateral(ML)displacement distance of body center of gravity under eye-opening and eye-closed states were calculated to evaluate pa-tients'weight-bearing and balance function. Result:After treatment,FMA-LE,CR and iEMG of biceps femoris and rectus femoris under knee flexion,tibialis anterior and medial gastrocnemius under ankle dorsiflexion were markedly ameliorated in the two groups(P＜0.01).After treatment,in the eye-opening state,the SI of mean pressure and contact area of both feet,elliptical area of body center of gravity,AP and ML displacement distances of body center of gravity were greatly enhanced in the two groups(P＜0.05,P＜0.01),in the eye-closed state,the SI of mean pressure and contact area of both feet,ML displacement distances of body center of gravity were observably ameliorat-ed in the two groups(P＜0.05,P＜0.01).Compared with the EMGBFT group,the FMA-LE,iEMG of biceps femoris and tibialis anterior muscles,elliptical area of body center of gravity,AP and ML displacement dis-tance of body center of gravity with eyes open,SI of contact area of both feet with eyes closed had more significant changes in the MT based EMGBFT group after treatment(P＜0.05,P＜0.01). Conclusion:Electromyographic biofeedback therapy combined with mirror therapy can improve lower limb motor and balance function in stroke patients,the underlying mechanism of which may be the activation of lower limb weak muscle motor units,the relief of lower limb spasm,and the improvement of standing static balance ability.

ObjectiveTo observe the effect of hyperbaric oxygen therapy (HBOT) combined with repetitive peripheral magnetic stimulation (rPMS) on ankle motor function and balance of stroke patients. MethodsFrom April, 2022 to March, 2023, 96 patients in the First Affiliated Hospital of Bengbu Medical College were randomly divided into control group (n = 32), rPMS group (n = 32) and combined group (n = 32). The control group received conventional rehabilitation; rPMS group received rPMS on the basis of the control group; and the combined group received HBOT on the basis of rPMS group, for two weeks. Before and after treatment, the plantar weight-bearing ratio of the affected side, Berg Balance Scale (BBS), active range of motion (AROM) of ankle dorsiflexion of the affected side, and integrated electromyographic (iEMG) values during maximum isometric contraction of the tibialis anterior and gastrocnemius muscles were measured. ResultsTwo cases dropped out in each group, and 90 cases were finally included, and no adverse events occurred during treatment. Before treatment, there was no significant difference in plantar weight-bearing ratio of the affected side, BBS score, AROM of ankle dorsiflexion of the affected side, and iEMG of tibialis anterior and gastrocnemius among three groups (F < 2.070, P > 0.05). After treatment, all the indicators significantly improved in all the groups (|t| > 27.004, P < 0.001), and they were better in the combined group than in rPMS group and the control group (P < 0.001); except the proportion of plantar weight-bearing on the affected side, the other indicators were better in rPMS group than in the control group (P < 0.001). ConclusionrPMS can promote the recovery of ankle motor function and balance of stroke patients, and the effect combining with HBOT is better.

Objective:To compare the short-term efficacy of hip arthroscopic surgery assisted by platelet-rich plasma (PRP) and hip arthroscopy alone in the treatment of femoroacetabular impingement (FAI).Methods:A retrospective cohort study was performed on the clinical data of 133 FAI patients admitted to Fourth Medical Center of PLA General Hospital from January 2019 to January 2021. The patients included 86 males and 47 females, aged 19-71 years [(39.1±12.6)years]. A total of 67 patients were treated with hip arthroscopy alone (hip arthroscopy group), and 66 patients were treated with PRP after hip arthroscopy under ultrasound guidance (hip arthroscopy+PRP group). The two groups were compared before, at 12 months after surgery and at the last follow-up regarding the following items: Visual Analogue Scale (VAS), Modified Harris Hip Score, International Hip Outcome Tool-12 (iHOT-12), and Hip Outcome Score Activities of Daily Living Scale (HOS-ADL). The incidence rate of complications after surgery was compared between the two groups.Results:A total of 108 patients were followed up for 24-36 months [(28.5±3.8)months], while 25 patients were lost to follow-up because of withdrawal of consent, wrong telephone number, etc, including 11 patients (16.4%) in the hip arthroscopy group and 14 patients (21.2%) in the hip arthroscopy+PRP group. The values of VAS in the hip arthroscopy group before, at 12 months after surgery and at the last follow-up were 5.00(5.00, 7.00)points, 3.00(2.00, 3.75)points, and 1.00(0.00, 2.00)points, respectively; the values of Modified Harris Hip Score were 49.00(39.00, 57.00)points, 76.00(69.25, 82.00)points, and 86.00(82.00, 88.00)points, respectively; the values of iHOT-12 were 0.45(0.28, 0.58)points, 0.69(0.58, 0.80)points, and 0.81(0.70, 0.92)points, respectively; the values of HOS-ADL were 0.52(0.42, 0.68)points, 0.87(0.75, 0.93)points, and 0.93(0.86, 0.99)points, respectively. The scores of VAS in the hip arthroscopy + PRP group before, at 12 months after surgery and at the last follow-up were 6.00(5.00, 7.00)points, 3.00(2.00, 3.75)points, and 1.00(0.00, 2.00)points, respectively; the values of Modified Harris Hip Score were 46.50(37.00, 56.75)points, 78.00(72.00, 84.00)points, and 84.50(82.00, 88.00)points, respectively; the values of iHOT-12 were 0.42(0.26, 0.51)points, 0.66(0.58, 0.74)points, and 0.81(0.68, 0.88)points, respectively; the values of HOS-ADL were 0.54(0.38, 0.65)points, 0.87(0.72, 0.96)points, and 0.94(0.86, 1.00)points, respectively. In both groups, VAS, Modified Harris Hip Score, iHOT-12, and HOS-ADL were significantly improved at 12 months after surgery and at the last follow-up compared with those before surgery, and were further improved at the last follow-up compared with those at 12 months after surgery (all P<0.01). There were no significant differences in VAS, Modified Harris Hip Score, iHOT-12 and HOS-ADL between the two groups before, at 12 months after surgery and at the last follow-up (all P>0.05). There was no significant difference in the incidence rates of postoperative hip pain and clicking between the two groups (both P>0.05). Conclusion:Hip arthroscopy can considerably improve short-term hip symptoms and function in FAI patients, but the use of PRP treatment after hip arthroscopy cannot further improve its short-term efficacy in FAI patients.

Objective: Empirical findings confirmed that autistic and schizotypal traits are associated with attentional function as well as include various dimensions. So far, no study has reported which dimension of these traits relates to attentional networks. This study aimed to find out whether there are associations between attentional networks and autistic traits; and between attentional networks and schizotypal traits. Methods: A total of 449 volunteers was included in this study, and autism-spectrum quotient (AQ), schizotypal personality questionnaire (SPQ), and attention network test (ANT) were used to measure autistic traits and schizotypal traits. The three independent attentional networks, including alerting network, orienting network, and executive control network, were also measured. Results: Autistic traits were associated with the orienting network, whereas schizotypal traits were associated with the orienting network and executive control network. Furthermore, attentional networks could be predicted by specific dimensions of autistic and schizotypal traits. AQ-attention switching [0.104 (-1.175– -0.025), p=0.041] and AQ-attention to detail [-0.097 (-0.798– -0.001), p=0.049] were significant predictors of orienting network and gender were significant predictor of executive network (Beta=0.107; 95% CI=-0.476–10.139; p=0.031). Whereas, schizotypal dimension “interpersonal” was a significant predictor of all three attentional networks [Alerting: 0.147 (-0.010–0.861), p=0.045; Orienting: 0.147 (0.018–0.733), p=0.040; Executive: 0.198 (0.215–1.309), p=0.006]. Conclusion This study demonstrated that autistic and schizotypal traits were associated with attentional networks. The specific dimensions of autistic and schizotypal traits could predict attentional networks. Nevertheless, the attentional networks predicted with these two traits were different.

To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.

Objective To analyze the feasibility and curative effects of one-stage reconstructing the anterior and posterior cruciate ligaments injuries with autologous hamstring tendon using TightRope devices all inside.Methods Thirty-four patients who suffered from the anterior and posterior cruciate ligaments injuries referred to our center from July 2013 to July 2015.Thirty-two of them with the average age 37.4±9.2 years old (range:18-61 years old),including 23 male and 9 female,were followed up over 2 years.According to the anatomy classification for knee dislocation,14 patients were KD Ⅱ type,11 patients KD Ⅲ M type,7 patients KD Ⅲ L type.The interval from injury to surgery was 4-6 weeks.One-stage reconstruction of the anterior and posterior cruciate ligaments was conducted by using autologous hamstring tendon with TightRope device all inside under arthroscopy.Ipsilateral hamstring tendon was taken in the patients of KD Ⅱ type,while opposite hamstring tendon was used in the patients of KD Ⅲ.The semitendinosus graft acted as posterior cruciate ligament,and gracilis graft acted as anterior cruciate ligament.Fold the tendon graft in half into four strands,with the length 6-7 cm,diameter 7-9 mm,and link together with two TightRope devices.The anterior and posterior cruciate ligaments injuries were reconstructed in one-stage with autologous hamstring tendon using TightRope all inside.The medial or lateral collateral ligament in patients of KD Ⅲ type was repaired.The anterior and posterior drawer test,Lachman test,valgus stress test,IKDC classification,Lysholm scores were recorded before and after surgery to evaluate the efficacy of reconstruction.Results Thirty-two patients who were treated with surgery were followed up 2-4 years with average 2.6 years.Preoperative symptoms relieved apparently in the last follow-up in all patients.The anterior and posterior drawer test and Lachman test were negative.The IKDC score of 27 patients at two years after surgery were rated as normal (84％),while that of 4 patients were rated as near normal (13％),1 patients as abnormal (3％).The rates of the normal and near normal were up to 97％.The overall score was improved from preoperation (36.4±4.6) to postoperation (90.1± 10.7,t=27.96,P=0.000).The knee function Lysholm scores was significantly increased from preoperation (52.7±5.3) to postoperation (91.5±9.2,t=23.26,P=0.000).Conclusion The one-stage reconstructing the anterior and posterior cruciate ligaments injuries with autologous hamstring tendon using TightRope devices all inside can recover the stability of knee joint with satisfied joint function postoperatively.

Objective To study the features and neural mechanism of pain empathy in autistic individuals.MethodsTotally 21 subjects with high level autistic traits and 22 subjects with low level autism traits completed the pain empathy task,recording RT and accuracy automatically.The event-related potentials(ERPs) were recorded by Neuroscan system simultaneously.Results(1)From the behavioral results,the IRI scores of the two groups had significant differences in the factors of perspective taking ((23.71±4.16) vs (26.95±3.24)),empathy concerning ((24.10±4.04) vs (26.36±2.82)) and personal distress ((24.19±3.59) vs (19.82±3.96)) (t=-2.86,P<0.01;t=-2.14,P<0.05;t=3.79,P<0.01).The factor of fantasy of the two groups didn't exit significant differences (t=-1.50,P>0.05).(2) According to the behavioral result of pain empathy test,the main effect of task type in reaction time and accuracy of the two groups had significant difference (F(1,41)=24.21,P<0.01;F(1,41)=152.10,P<0.01),but the main effect of emotion type and group didn't reach significant level (F(1,41)=1.11,P>0.05,F(1,41)=0.29,P>0.05;F(1,41)=3.20,P>0.05,F(1,41)=0.14,P>0.05).(3)From the results of ERP,the main effect of emotion type,task type and group didn't reach the significant level in the N2 amplitude of the two groups(F(1,41)=0.04,P>0.05;F(1,41)=0.08,P>0.05;F(1,41)=3.86,P>0.05).The main effect of emotion type had significant difference in the P3 amplitude of the two groups(F(1,41)=8.27,P<0.01),but there was no significant difference in the main effect of task type and group(F(1,41)=2.48,P>0.05,F(1,41)=0.25,P>0.05).It had significant difference in LPP amplitude in the main effect of emotion type,task type and group(F(1,41)=32.07,P<0.01;F(1,41)=8.63,P<0.01;F(1,41)=4.73,P<0.05).ConclusionsThere are differences in the abilities of empathy between the high and low level autistic traits groups,especially in the late processing of pain empathy.
