The concept of "spirit" in traditional Chinese medicine （TCM） aligns closely with "the liver governs the designing of strategy". By exploring the relationship between the liver and executive function decline， it is proposed that prolonged liver constraint leads to indecisiveness in strategy designing， which is the initiating factor for executive function decline； liver blood deficiency causes difficulties in executing strategy， which forms an essential foundation for the progression of executive function decline； obstruction in the "liver-du mai-brain" pathway leads to unclear strategy designing， which accelerates executive function decline. This relationship is examined from the perspectives of TCM， modern medicine， and cognitive psychology， aiming to provide insights into addressing executive function decline through treatments focused on the liver.

Venous adventitial cystic disease(VACD)is a rare vascular disease which often manifests as unilateral limb swelling,and so misdiagnosed as other diseases such as deep vein thrombosis.Color Doppler ultrasound,CT angiography and magnetic resonance imaging play a crucial role in the diagnosis of VACD.Surgical treatment is the main method for VACD,including cyst incision,cyst wall resection,cyst puncture,aspiration and cyst and vessel resection.The recurrence rate of VACD is relatively high,ranging from 20%to 83%.Enhancing the understanding of VACD,making accurate diagnoses and appropriate surgical operation are of great significance for improving treat-ment outcomes and reducing the recurrence rate.

Objective:To investigate the genetic, clinical, and post-treatment characteristics of patients with glycogen storage disease type Ⅲ (GSD Ⅲ).Methods:A retrospective cohort analysis was performed on the genetic and clinical data of 26 cases with GSD Ⅲ who visited the Children's Hospital affiliated with Fudan University from June 2017 to December 2023. The patients were divided into non-missense variation and missense variation groups according to the types of mutation in the AGL gene.The correlation between genotype and phenotype was analyzed. All patients were treated with uncooked cornstarch after diagnosis. The changes before and after treatment were compared in patients who underwent more than twelve months of follow-up. A P value of <0.05 was used to denote statistical significance. Results:Among the 26 cases enrolled, 13 were female and 13 were male, and the median age of diagnosis was 28 (6 to 134) months. A total of thirty-five different types of AGL gene variation were detected, with c.1735+1G＞T (9/52, 17.3%) as the hotspot variation. The common clinical manifestations were elevated aminotransferases (26/26, 100%), hepatomegaly (25/26, 96.2%), fasting hypoglycemia (25/26, 96.2%), hyperketonemia (16/18, 88.9%), hypertriglyceridemia (TG) (20/26, 76.9%), elevated CK (16/25, 64.0%), and an abnormal electrocardiogram (12/16, 75.0%). Four cases (15.4%) had symptoms of myopathy at diagnosis. Liver biopsy was performed in eighteen cases, among whom 83.3% (15/18) had liver fibrosis≥S2. The number of cases with elevated levels of CK ( P＝0.031) and ALT ( P＝0.038)was pronounced in the non-missense variation group compared to that in the missense variation group. There were no statistically significant differences in age, height, liver size, degree of fibrosis, fasting blood glucose (Glu) and TG ( P>0.05). The median follow-up time of 14 cases was 40.5 (20-73) months, with improvement in body stature, reduced liver size, decreased ALT and TG, and improved Glu. However, four (28.6%) cases had new myopathy symptoms with raised CK ( P<0.05) and with advancing age, increased ALT diminished while CK level elevated ( P<0.05). Conclusions:The common clinical manifestations at the early stage of the GSD Ⅲdiagnosis are elevated aminotransferases, hepatomegaly, fasting hypoglycemia, hyperketonemia, high triglycerides, elevated CK, and fibrotic liver in China. Myopathy symptoms may arise following uncooked cornstarch treatment; however, there is significant improvement in height, liver-related, and metabolic parameters.

Objective:To explore the clinical effects of flaps or myocutaneous flaps transplantation after debridement to repair the wounds with exposed titanium mesh after cranioplasty on the premise of retaining the titanium mesh.Methods:This study was a retrospective observational study. From February 2017 to October 2022, 22 patients with titanium mesh exposure after cranioplasty who met the inclusion criteria were admitted to the Department of Plastic, Aesthetic & Maxillofacial Surgery of the First Affiliated Hospital of Xi'an Jiaotong University, including 15 males and 7 females, aged from 19 to 68 years. After admission, treatments such as bacterial culture of wound exudate sample, anti-infection, and dressing change were carried out. Thorough surgical debridement was performed when the wound improved, and the wound area was 3.0 cm×2.0 cm to 11.0 cm×8.0 cm after debridement. The wound was repaired with local flaps, expanded flaps, or free latissimus dorsi myocutaneous flaps according to the size, location, severity of infection, and surrounding tissue condition of the wounds, and the areas of flaps or myocutaneous flaps were 5.5 cm×4.0 cm to 18.0 cm×15.0 cm. The donor areas of flaps were sutured directly or repaired by split-thickness skin grafts from head. The wound repair method was recorded. The survivals of flaps or myocutaneous flaps after surgery and wound healing in 2 weeks after surgery were recorded. During postoperative follow-up, recurrence of infection or titanium mesh exposure in the implanted area of titanium mesh was observed; the head shapes of patients, scar formation of the operative incision, and baldness were observed. At the last follow-up, the satisfaction of patients with the treatment effect (dividing into three levels: satisfied, basically satisfied, and dissatisfied) was evaluated. The total treatment costs of patients during their hospitalization were calculated.Results:The wounds in 11 cases were repaired with local flaps, the wounds in 5 cases were repaired with expanded flaps, and the wounds in 6 cases were repaired with free latissimus dorsi myocutaneous flaps. All flaps or myocutaneous flaps survived completely after surgery, and all wounds healed well in 2 weeks after surgery. Follow up for 6 to 48 months after operation, only one patient with local flap grafting experienced a recurrence of infection in the titanium mesh implanted area at more than one month after surgery, and the titanium mesh was removed because of ineffective treatment. Except for one patient who had a local depression in the head after removing the titanium mesh, the rest of the patients had a full head shape. Except for myocutaneous flap grafting areas in 6 cases and skin grafting area in 1 case with local flaps grafting had no hair growth, the other patients had no baldness. All the scars in surgical incision were concealed. At the last follow-up, 19 cases were satisfied with the treatment effects, 2 cases were basically satisfied, and 1 case was dissatisfied. The total treatment cost for patients in this group during hospitalization was 11 764-36 452 (22 304±6 955) yuan.Conclusions:For patients with titanium mesh exposure after cranioplasty, on the premise of adequate preoperative preparation and thorough debridement, the wound can be repaired with appropriate flaps or myocutaneous flaps according to the wound condition. The surgery can preserve all or part of the titanium mesh. The postoperative wound healing is good and the recurrence of infection or titanium mesh exposure in the titanium mesh implanted area is reduced, leading to good head shape, reduced surgical frequency, and decreased treatment costs.

Objective:To compare the short-term efficacy of drug-coated balloon and common balloon in the treatment of with below-the-ankle arteriosclerosis obliterans (ASO).Methods:The clinical and follow-up data of 115 patients (118 limbs) with lower extremity ASO of Rutherford 4-6 admitted to the Department of Peripheral Vascular Diseases, Xiyuan Hospital, China Academy of Chinese Medical Sciences from Jun 2021 to Jun 2023 were retrospectively analyzed.Results:Patients were divided into group of 52 limbs using paclitaxel-coated balloon and group of 66 limbs using common balloon. During the 6-month follow-up period, The total effective rate of wound surface was 98.1% in the drug-coated balloon group and 92.4% in the common balloon group. The difference was statistically significant ( P<0.05); the increase of ankle-brachial index (ABI) and toe-brachial index (TBI) in the drug-coated balloon group were significantly better than common balloon group, and the difference was statistically significant ( P<0.01). No major adverse events occurred in the two groups during the 6-month follow-up period. Compared with the common balloon group, the drug-coated balloon group had a higher limb salvage rate (100.0% vs. 98.5% ) and a lower target vessel reconstruction rate (7.7% vs.18.2%), though the difference was not statistically significant ( P>0.05). Conclusion:Compared with the common balloon, the drug-coated balloon is more effective in the treatment of patients with wound healing rate and vascular patency rate in Rutherford 4-6 grade below-the-ankle artery lesions.

Type 2 diabetes mellitus (T2DM) therapy is facing the challenges of long-term medication and gradual destruction of pancreatic islet β-cells. Therefore, it is timely to develop oral prolonged action formulations to improve compliance, while restoring β-cells survival and function. Herein, we designed a simple nanoparticle with enhanced oral absorption and pancreas accumulation property, which combined apical sodium-dependent bile acid transporter-mediated intestinal uptake and lymphatic transportation. In this system, taurocholic acid (TCA) modified poly(lactic-co-glycolic acid) (PLGA) was employed to achieve pancreas location, hydroxychloroquine (HCQ) was loaded to execute therapeutic efficacy, and 1,2-dilauroyl-sn-glycero-3-phosphocholine (DLPC) was introduced as stabilizer together with synergist (PLGA-TCA/DLPC/HCQ). In vitro and in vivo results have proven that PLGA-TCA/DLPC/HCQ reversed the pancreatic islets damage and dysfunction, thus impeding hyperglycemia progression and restoring systemic glucose homeostasis via only once administration every day. In terms of mechanism PLGA-TCA/DLPC/HCQ ameliorated oxidative stress, remodeled the inflammatory pancreas microenvironment, and activated PI3K/AKT signaling pathway without obvious toxicity. This strategy not only provides an oral delivery platform for increasing absorption and pancreas targetability but also opens a new avenue for thorough T2DM treatment.

Objective:To investigate the risk factors related to the contrast-induced nephropathy(CIN)occurring after carotid artery stenting(CAS)in patients with carotid artery stenosis.Methods:The clinical data of 137 patients with carotid artery stenosis, who were treated with CAS at Xuanwu Hospital, Capital Medical University during the period from January to Decmber 2021 were retrospectively analyzed. Record demographic characteristics (age, gender, height, weight), history of underlying diseases (hypertension, diabetes, kidney disease, etc.), history of medications, etc. Observe the clinical parameters such as creatinine, blood urea nitrogen, albumin, hemoglobin, hematocrit, degree of stenosis and estimated glomerular filtration rate (eGFR). Measurement data conforming to the normal distribution were expressed as the mean±standard deviation( ± s), and the t-test was used for comparison between groups; the measurement data that does not conform to the normal distribution were expressed as the median (interquartile range) [ M( Q1, Q3)], and the Rank-sum test was used for comparison between groups; the Chi-square test or Fisher exact test was used for comparison of count data between groups. Relevant variables were subjected to univariate analysis, and statistically significant indicators were selected according to the results of univariate analysis to be included in the multivariate Logistic regression analysis. Results:After CAS, a total of 29 patients (21.2%) among the 137 patients developed CIN. Univariate analysis indicated that bilateral carotid artery stenosis, uncontrolled hypertension before surgery, history of angiotensin converting enzyme inhibitor drugs, diabetes mellitus, history of insulin drugs, eGFR<45 mL/(min·1.73 m 2), body weight were the influencing factors associated with the occurrence of CIN after CAS in patients with carotid artery stenting; multivariate regression analysis revealed that the presence of bilateral carotid artery stenosis( OR=4.724, 95% CI: 1.455-15.338, P=0.010), diabetes mellitus( OR=3.451, 95% CI: 1.345-8.858, P=0.010) and eGFR <45 mL/(min·1.73 m 2)( OR=4.582, 95% CI: 1.001-20.971, P=0.050) were the independent risk factors related to the CIN after CAS. Conclusion:Patients with the presence of bilateral carotid artery stenosis, diabetes mellitus or eGFR <45 mL/(min·1.73 m 2) are more likely to develop CIN after CAS.

Objective:To identify the genetic variation in a mucopolysaccharidosis type Ⅱ(MPS Ⅱ)family, and conduct a functional study of iduronate-2-sulfatase(IDS): c.323A>C.Methods:A five-generation MPS Ⅱ family of 83 individuals including 4 patients from northern China was collected. Urine mucopolysaccharide and Alder-Reilly body were tested to assist the clinical diagnosis of MPS Ⅱ. IDS enzyme activity was detected on core family members. By the whole exome sequencing of a MPS Ⅱ patient in this family and bioinformatics analysis, the variant was screened and further identified by PCR-Sanger sequencing. Finally, to validate the function of the variant in vitro, the wild-type IDS overexpression plasmid(pCMV-hIDS-WT)and the IDS overexpression plasmid carrying the mutation site(pCMV-hIDS-c.323A>C)were transfected into COS-7 cells and the IDS activity was detected. Results:The proband(Ⅳ3)and Ⅳ4 were diagnosed as MPS Ⅱ by urine mucopolysaccharide, Alder-Reilly body, and IDS enzyme activity tests. Ⅳ3, Ⅳ4, Ⅲ19, and Ⅲ32 were determined to carry IDS: c.323A>C missense variant through the whole-exome sequencing, and diagnosed as MPS Ⅱ. Meanwhile, Ⅱ2, Ⅱ4, Ⅱ8, Ⅱ12, Ⅱ14, Ⅲ5, Ⅲ7, Ⅳ14 in the MPS Ⅱ family carried IDS: c.323A>C missense variant, and were excluded as MPS Ⅱ. The in vitro experiment in COS-7 cells showed that the missense mutation led to a significant decrease in IDS enzyme activity. Conclusion:The variant IDS: c.323A>C: p.Y108S significantly decreases the activity of IDS enzyme in vivo and in vitro, and it is identified as a pathogenic variant for MPS Ⅱ.

Objective:To investigate the efficacy of 3D-printed quantitative bone implants assisting second-stage Masquelet technique for the treatment of long-segment bone defect following Gustilo type IIIB and IIIC tibial fractures.Methods:A retrospective case series analysis was made on 26 patients with long-segment bone defect following Gustilo type IIIB and IIIC tibial fractures treated in Wuxi Ninth People′s Hospital from July 2015 to December 2020, including 20 males and 6 females; aged 19-63 years [(46.5±4.5)years]. Gustilo classification was type IIIB in 23 patients and type IIIC in 3. In the first stage, all patients had thoroughly emergent debridement, removal of all free bone pieces, restoration of the length and force line plus externally fixion, and vacuum sealing drainage (VSD) of the residual wound. After 2-7 days, the external fixation was removed and replaced by internal fixation, with the bone cement filling in the defect area and the free flap covering the wound. The length of tibial bone defect was 5-14 cm [(6.3±0.4)cm], and the tibial defect volume was 12.2-73.1 cm 3 [(33.6±9.2)cm 3]. In the second stage (6-19 weeks after injury), the bone cement was removed, followed by autologous bone grafting. Prior to bone grafting, digital technology was used to accurately calculate the bone defect volume, and an equal volume of bone harvesting area was designe to produce the 3D printed osteotomy template. Bone grafting was conducted after bone removal according to the osteotomy template during operation. The success rate of one-time iliac bone extraction, bone harvesting time, and bleeding volume were recorded. Pain in the bone extraction area was evaluated by visual analogue score (VAS) at 1 day and 1 month after operation and at the last follow-up. Wound healing, complications, and bone healing were observed. Life quality was evaluated by health survey brief form (SF-36) including scores of physical component summary (PCS) and mental component summary (MCS) before bone grafting and at the last follow-up. Results:All the patients were followed up for 13-53 months [(32.3±12.5)months]. One-time iliac bone extraction was successful in all the patients. Bone harvesting time was 15-30 minutes [(21.0±2.5)minutes]. The bleeding volume was 50-120 ml [(62.3±29.0)ml]. The VAS was 1-4 points [(1.2±0.9)points] at 1 day after operation, higher than these (0.0±0.0)points at 1 month after operation and at the last follow-up (all P<0.01). Totally, 25 patients obtained wound healing after operation, except for 1 patient with superficial wound infection after bone grafting that was healed by dressing change. There was 1 patient with bone infection after 3 months of bone grafting that was healed by repeated surgery with Masquelet technique in the first and second stage. Besides, 2 patients had symptoms of cutaneous nerve injury in the iliac donor area. The time of bone healing was 4-7 months [(5.8±0.8)months]. The scores of PCS and MCS in SF-36 at the last follow-up were (73.6±12.8)points and (83.6±13.2)points, significantly higher than those before bone grafting [(46.8±0.5)points, (60.7±2.0)points] (all P<0.01). Conclusion:Second-stage Masquelet technique with 3D printed quantitative bone implants for the treatment of long-segment bone defect following Gustilo type IIIB and IIIC tibial fractures is associated with shortened bone harvesting time, attenuated pain, reduced complications, accelerated bone healing and improved function.

Objective:To analyze the local recurrence patterns after concurrent chemoradiotherapy (CCRT) for thoracic esophageal squamous cell carcinoma (ESCC) through image fusion, and to explore the risk factors of local recurrence and its relationships with dosimetric indices.Methods:A retrospective analysis was conducted for 209 thoracic ESCC patients who received radical CCRT in Fourth Hospital of Hebei Medical University during 2016-2019. For the patients diagnosed as the local recurrence of esophageal lesions, their CT images were fused with the original planning CT images using image registration software to identify the recurrence sites. Through 1∶1 propensity score matching (PSM) of the clinal data of patients with local recurrence (the recurrence group, nbefore = 81, nafter = 62) and those without local recurrence (the recurrence-free group, nbefore = 128, nafter=62), the dose and volume parameters of the treatment plans for the two groups were compared. Univariate and multivariate analyses were conducted using the Kaplan-Meier method and the Cox regression model to analyze the factors affecting the overall survival (OS), progression-free survival (PFS), and recurrence-free survival (RFS). Results:All patients had 1-, 3-, and 5-year OS rates of 80.9%, 42.6%, and 33.0%, respectively, 1-, 3-, and 5-year PFS rates of 67.9%, 34.0%, and 27.9%, respectively, and 1-, 3-, and 5-year RFS rates of 71.3%, 39.2%, and 30.5%, respectively. T stage, N stage, and radiation dose were independent prognostic factors for the OS, PFS, and RFS ( HR = 1.42-1.87, P < 0.05) of the patients, respectively. Among 68 patients with local recurrence, 62 cases (91.2%) suffered recurrence within the gross tumor volume (GTV). The dose and volume parameters of patients with local recurrence, such as GTV- D95%, clinical target volume (CTV)- D95%, GTV- D50%, CTV- D50%, and planning target volume (PTV)- D50%, GTV- V60, CTV- V60, and PTV- V60, were significantly lower than those of patients free from the local recurrence ( t=1.90-2.15, P < 0.05). Conclusions:Local recurrence of patients with thoracic ESCC after radical CCRT occurs mainly within the GTV. Increasing radiation doses may contribute to their survival benefits. The D50% for each target volume in the radiotherapy plan may be related to local recurrence, and it is necessary to conduct further research.
