By reconstructing the integrated Chinese and western medicine diagnostic and treatment system， the "Two Reconstructions" theoretical framework establishes a standardized pathway of "classification-staging-syndrome differentiation"， which improves the accuracy of disease identification and strengthens the capacity for full-course intervention； in addition， by reconstructing the modern materia medica system， it innovatively integrates the traditional properties and efficacy of Chinese herbal medicinals with modern pharmacological mechanisms， forming a "state-target co-regulation" precise medication model， and builds a dose-effect theoretical system for prescriptions and medicinals， thereby enhancing both the targeting accuracy and dosage precision of therapeutic interventions. The "Two Reconstructions" theorecitcal framework is a key strategy for enhancing clinical efficacy. It can precisely identify "states" and "targets" for directed intervention， shift the focus of prevention and treatment earlier to enable full-cycle management， establish standardized paradigms for reproducible and evaluable efficacy， and expand the scope of clinical practice to address conditions without typical syndromes and critical illnesses. As a systematic pathway for innovation in TCM， this theoretical framework provides valuable insights and references for promoting the high-quality development of integrative Chinese and western medicine.

Objective To explore the relationship between triglyceride-glucose index(TyG)and acute ischemic stroke with large vessel occlusion(AIS-LVO)of anterior circulation.Methods A retrospective study was conducted on patients with anterior circulation AIS-LVO who underwent emergency endovascular thrombectomy at Neurovascular Center of The First Affiliated Hospital of Naval Medical University from Jan.2018 to Dec.2019.According to modified Rankin scale(mRS)score 90 d after operation,the patients were assigned to favorable outcome group(mRS score 0-2)or unfavorable outcome group(mRS score 3-6),and the TyG was compared.According to the median of TyG,the patients were assigned to low-TyG group(TyG＜8.57)or high-TyG group(TyG ≥8.57),and the clinical data,laboratory indexes,and imaging characteristics were compared.Receiver operating characteristic curve was used to evaluate the predictive value of TyG for poor prognosis.Results A total of 135 patients were enrolled,with 72 in the favorable outcome group and 63 in the unfavorable outcome group.The TyG of the unfavorable outcome group was significantly higher than that of the favorable outcome group(8.82+0.63 vs 8.43+0.60,P＜0.001).There were 67 patients in the low-TyG group and 68 in the high-TyG group.Compared with the low-TyG group,the proportion of patients with hyperlipidemia history(P=0.003),systolic blood pressure at admission(P=0.018),fasting blood glucose level(P＜0.001),and triglyceride level(P＜0.001)were significantly higher in the high-TyG group,the infarct core volume was significantly larger(P=0.025),the high density lipoprotein-cholesterol level was significantly lower(P=0.013),and the mRS score 90 d after operation was significantly higher(3[1,5]vs 1[0,5],P=0.049).The TyG had certain predictive value for poor prognosis in anterior circulation AIS-LVO patients(area under curve value=0.662,95％confidence interval 0.571-0.753).Conclusion TyG is elevated in anterior circulation AIS-LVO patients with poor prognosis,and may be a potential prognostic indicator for anterior circulation AIS-LVO patients.

Objective To investigate the safety and effectiveness of endovascular treatment in patients with acute ischemic stroke due to large vessel occlusion(AIS-LVO)over 24 h after onset.Methods The clinical data of AIS-LVO patients who received endovascular treatment in Neurovascular Center of The First Affiliated Hospital of Naval Medical University from Jan.2018 to Dec.2022 were retrospectively analyzed,including baseline characteristics,imaging findings,treatment,degree of vascular recanalization(modified thrombolysis in cerebral infarction grade 2b and 3 for successful recanalization)and prognosis.Results A total of 57 patients were included,including 42 males and 15 females,aged from 30 to 84 years old.The most common risk factors were hypertension(39 cases,68.4%),followed by smoking history(24 cases,42.1%),diabetes mellitus(17 cases,29.8%),previous stroke history(16 cases,28.1%),and atrial fibrillation(9 cases,15.8%).Before treatment,the National Institutes of Health stroke scale score was 12.84±7.04,and the Alberta Stroke Program early computed tomography score was 9.00(7.00,10.00).Vascular occlusion sites included middle cerebral artery occlusion in 27(47.4%)cases,internal carotid artery occlusion in 24(42.1%)cases,and tandem lesions in 6(10.5%)cases.The time from onset to femoral artery puncture was 38.30(28.17,53.71)h,and the time from femoral artery puncture to vascular recanalization was 52.00(38.50,92.50)min.General anesthesia was the main anesthesia method,accounting for 64.9%(37/57).The etiological types of stroke were mainly large artery atherosclerosis(38 cases,66.7%),cardiogenic embolism(9 cases,15.8%),unknown causes(6 cases,10.5%),and other clear causes(4 cases,7.0%).Mechanical thrombectomy was the first choice in 41(71.9%)cases,balloon dilatation/stenting was used in 35(61.4%)cases,of which 15(26.3%)cases were the first choice.Finally,53(93.0%)cases were recanalized successfully.In terms of complications,1(1.8%)case had symptomatic intracranial hemorrhage.The 90-d prognosis rate was 59.6%(34/57),and 3(5.3%)cases died.Conclusion Endovascular treatment for AIS-LVO patients over 24 h after onset has high recanalization rate and good safety,but it still needs to be further verified by randomized controlled trials.

Objective:To analyze the correlation between thymus dose-volume parameters and lymphopenia in patients with early-stage breast cancer (BC) receiving adjuvant radiotherapy (RT).Methods:Medical records of 54 patients with early-stage BC who received postoperative adjuvant RT in the Second Affiliated Hospital of Soochow University from January to December 2019 were retrospectively analyzed. Absolute lymphocyte counts (ALC) were collected at 1 month before (baseline) and weekly during RT. Lymphopenia was graded based according to the common terminology criteria for adverse events version 5.0 and nadir/baseline ALC was calculated. The thymus was delineated according to anatomical boundaries in the original RT planning system. Dosimetric parameters were obtained from the dose volume histograms. Stepwise multiple linear regression analysis was used to explore the factors associated with nadir/baseline ALC. The cutoff values of dosimetric parameters for predicting ≥grade 3 lymphopenia were obtained using the receiver operating characteristic (ROC) curve.Results:The proportion of 54 patients experiencing ≥ grade 3 lymphopenia was 38.9%. The median value of thymus volume, mean dose, V 5 Gy, V 10 Gy were 14.02 cm 3, 4.95 Gy, 36.18%, and 6.61%, respectively. Stepwise multiple linear regression analysis revealed that baseline ALC ( P=0.005), quadrant location ( P=0.005) and mean thymus dose ( P<0.001) were significantly associated with nadir/baseline ALC. ROC curve analysis indicated that the cutoff values of thymus mean dose, V 5 Gy and V 10 Gy for predicting ≥ grade 3 lymphopenia were 6.12 Gy, 35.2%, and 7.4%, respectively. Conclusions:Lymphopenia in early-stage BC patients is significantly correlated with high dosimetric parameters of the thymus during postoperative adjuvant RT. Thymus may be considered as an organ at risk during RT.

Objective To classify the foot types of young Chinese males,extract characteristic indicators of foot types,and construct a standard foot type database.Methods Foot type data from 1 483 healthy young male individuals were collected.Spectral clustering algorithm was utilized to categorize foot types,and a deep neural network(DNN)was employed for training the classification model.Layer-wise relevance propagation(LRP)and the correlation coefficient method were combined to extract foot type features,and the differences in various foot type characteristics were compared.Results Spectral clustering yielded 4 distinct foot type categories.Foot type 1 was characterized by a high-arched foot with a prominent big toe,inwardly rotated 5th toe,and a high heel with a wide foot;foot type 2 was characterized by a narrow foot with hallux valgus;foot type 3 was characterized by a low-arched foot with hallux valgus;foot type 4 was characterized by a high-arched foot with a prominent big toe.By integrating interpretable neural networks and the correlation coefficient method,nine indicators were extracted from 27 foot type indicators,including the heel to the sole length,hallux height,navicular bone height,lateral malleolus height,hallux valgus angle,5th toe angle,dorsal foot circumference,heel angle,and longitudinal arch angle.The classification model constructed with these extracted indicators achieved an overall discrimination accuracy rate of 93.67％.Conclusions Chinese young males can be classified into four typical foot types.By examining the rearfoot,midfoot,and forefoot regions,nine key foot morphology parameters,including length,height,circumference,and angle,can be extracted.These parameters provide both theoretical and empirical support for establishing normative data on foot morphology for Chinese young males and for advancing biomechanical researches on the foot and ankle.

Objective To explore the effect of cognitive-motor dual tasks with different cognitive loads(none,simple and difficult)on activation of prefrontal cortex and static posture control in young man.Methods From June to July,2024,27 healthy male college students were recruited in Hebei Normal University.Static postural control parameters(C90 area),lower limb electromyography data(muscle energy proportion)and pre-frontal cortex hemodynamic signals of subjects under single task without cognitive load,dual-task with simple cognitive load,and dual-task with difficult cognitive load were collected using a balanced testing and training system,a wireless surface electromyography device,and functional near-infrared spectroscopy technology.Results The C90 areas of dual-tasks with simple and difficult cognitive load were smaller than that of the single task without cognitive load(P<0.05).The proportion of β band energy in the medial and lateral gastrocnemius mus-cles in the dual-task with simple cognitive load was greater than that in the single task without cognitive load(P<0.05),while the proportion of piper band energy in the lateral gastrocnemius muscle and tibialis anterior muscle was less(P<0.05).During dual-task with difficult cognitive load,the activation levels of bilateral ventro-lateral prefrontal cortex and right dorsolateral prefrontal cortex were higher than those in the single task without cognitive load(P<0.05).Conclusion Dual tasks with appopriate cognitive loads are effective on postural stability in young man.Simple cognitive load promote posture maintenance through optimizing the neuromuscular control of the lower limb muscle groups,while difficult cognitive load through activating the right prefrontal cortex involved in working memory and executive control,involving the neurocognitive compensatory.

Objective To explore the correlation between single-leg standing posture control and ankle plantar flexor muscle stability,so as to provide a new theoretical basis for improving the ability of human posture control.Methods A total of 20 healthy male college students were randomly selected as the experimental subjects.The iBalance tester and training system was used to test the trajectory data of the center of pressure(COP)of the foot standing on one leg.The CON-TREX MJ multi-joint isokinetic test and training system was used to test the moment amplitude data during the contraction of ankle plantar flexor muscles.Univariate repeated measures variance analysis was used to analyze the standard deviation data of ankle plantar flexor moment amplitude between groups.The Pearson correlation coefficient was used to study the correlation.Results The greater the intensity of the muscle stabilization task performed by the ankle plantar flexor muscle,the greater the standard deviation of the moment amplitude.The C90 area was positively correlated with the coefficient of variation(CV)of the 10％maximum voluntary contraction(MVC)moment of ankleplantar flexor muscle(r=0.761,P＜0.05)during single-leg standing without interference.The C90 area was positively correlated with the CV(r=0.632,P＜0.05)of the 30％MVC moment of ankle plantar flexor muscle during single-leg standing.When the proprioception was interfered during single-leg standing,the C90 area was positively correlated with the CV(r=0.583,P＜0.05)of the 20％MVC moment amplitude of ankleplantar flexor muscle.Conclusions With the increasing difficulty of muscle strength stabilization performed by the ankle plantar flexor muscles,muscle stability decreases.There is a positive correlation between ankle plantar flexor strength stability and single-leg standing posture control.Compared with the case without interference,under visual and proprioceptive interference,an additional information input is reduced or disturbed,and it is more difficult to maintain body balance,and the ankle plantar flexor muscle needs a higher muscle stability in the force mode to participate in the posture control of the human body during single-leg standing.
