This paper analyzed the "non-standardization" phenomenon of syndrome differentiation in traditional Chinese medicine （TCM） from the diagnosis process. It is proposed that the symptoms and signs collected by the four examinations of inspection， listening/smelling， inquiry， and palpation naturally have a certain "ambiguity"， which can be reduced by the comparison and comprehensive condensation （comprehensive analysis of the four examinations） of a large amount of multi-dimensional clinical data， thereby realizing the sublimation of TCM diagnosis from "ambiguity" of four examinations to "accuracy" of diagnostic conclusion. Based on the above assumptions， this paper further proposed that a research idea of intelligent syndrome differentiation in TCM， that is， by taking the clinical thinking ability of TCM physicians as the core， adopting artificial intelligence technology based on knowledge graph visualization， integrating the complex network association and reasoning method of "symptom-pathogenesis-syndrome" linked by pathogenesis， and through the automatic analysis and reasoning process of a large amount of multi-dimensional and ambiguous clinical data， the intelligent TCM diagnosis based on syndrome differentiation can be realized.

Lipedema is a disease in which local fat deposits in the body are the main clinical manifestations. It is often characterized by a disproportionate increase in subcutaneous fat tissue in the extremities, buttocks or hip joints. It is often misdiagnosed as obesity or lymphedema in clinical practice. The pathogenesis is not clearly understood, and there is no standardized clinical treatment method. This paper elaborated on the research status of the pathogenesis of lipedema, and summarized the clinical manifestations and classification, diagnosis and differential diagnosis, treatment methods, etc., aiming to provide up-to-date perspectives of lipedema.

Objective:Previous studies have revealed a correlation between eosinophils and allergic rhinitis,but the causal relationship has not been fully confirmed.This study aims to evaluate the causal link between blood eosinophils and allergic rhinitis using the Mendelian randomization(MR)method. Methods:Summary data from the Genome-Wide Association Study Catalog(GWAS)for eosinophil count(exposure variable)and allergic rhinitis(outcome variable)were collected.GWAS data for the exposure variable were obtained from the IEU Open GWAS Project developed by the Integrative Epidemiology Unit at the University of Bristol,while data for the outcome variable were sourced from the FinnGen Biobank(Finland)database.The causal relationship between eosinophils and allergic rhinitis was analyzed using the two-sample MR method with inverse variance weighted(IVW)analysis.Sensitivity analyses were conducted using the weighted median method,MR-Egger regression,leave-one-out analysis,and funnel plots. Results:An increase in blood eosinophil count showed a potential causal relationship with an increased risk of allergic rhinitis(OR=1.187,95%CI 1.051 to 1.341,P=0.006).This finding was consistent across the weighted median method and MR-Egger regression.Leave-one-out analysis indicated that no single nucleotide polymorphism significantly influenced the causal inference. Conclusion:There is a causal association between increased eosinophil count and a higher risk or worsening of allergic rhinitis.

Objective To explore the effect of multiparameter electroencephalogram(EEG)-guided anesthesia management on EEG burst suppression(BS)and postoperative delirium(POD)in elderly patients undergoing lower abdominal laparoscopic surgery.Methods A total of 100 elderly patients,48 males and 52 females,aged 65-85 years,BMI 18.5-28.0 kg/m2,and ASA physical status Ⅱ or Ⅲ,were enrolled for lower abdominal surgery under general anesthesia.Patients were randomly divided into two groups:multiparameter group and single parameter group,50 patients in each group.In multiparameter group,multiparameter EEG monitoring with patient statu index(PSI),spectral edge frequency(SEF),burst suppression ratio(BSR)and density spectral array(DSA)were used to guide the depth management of anesthesia.In single parameter group,single parameter PSI was used to guide the depth management of anesthesia.The total area under the hypotensive threshold of MAP(AUTMAP)was calculated,and the amount of anesthetic used during the operation and the use of vasoactive drugs,duration of anesthesia,extu-bation time,duration of PACU stay,and postoperative hospitalisation days were recorded.HR,MAP,PSI,and SEF were recorded before the induction of anesthesia,5 minutes after induction of anesthesia,5,30,and 60 minutes after incision,and at the end of surgery.The incidence,duration,and maximum BSR of in-traoperative BS,as well as the incidence of POD 1,2,and 3 days after surgery were recorded.Results There was no significant difference in AUTMAP values between the two groups.Compared with single parame-ter group,intraoperative propofol and remifentanil dosage were significantly decreased(P＜0.05),awak-ening time,PACU stay,and postoperative hospitalization time were significantly shorter in multiparameter group(P＜0.05),the PSI was significantly increased 5,30,and 60 minutes after incision and at the end of surgery,and the SEF was significantly increased 5 minutes after induction of anesthesia,5,30,and 60 minutes after induction and the end of surgery(P＜0.05).Compared with single parameter group,inci-dence of intraoperative BS was significantly decreased,duration of BS was significantly shorter,smaller maximum BSR was significantly decreased,and incidence of POD on 1 day after surgery in multiparameter group(P＜0.05).Conclusion Anesthesia management guided by multiparameter EEG can inhibit the oc-currence of BS,mitigate the degree of BS,and reduce the incidence of POD in elderly patients undergoing abdominal surgery.

Objective:To explore the role and mechanism of miR-485-5p targeted regulation of WNT7B in regulating osteogenic differentiation of bone marrow mesenchymal stem cell (BMSC). Methods:15 osteoporotic patients who underwent hip replacement due to hip fracture in Tianjin Hospital from January to October 2023 were collected, and bone tissues in the femoral head in the area of reduced bone density detected by the dual-energy X-ray absorptiometry (DXA) method were collected (osteoporosis group); 15 patients who underwent joint replacement due to osteoarthritis were matched according to their age and body mass index, and bone tissues in the femoral head in the area of normal bone density were collected (no osteoporosis group). MiR-485-5p and WNT7B were detected using qRT-PCR technology; the target genes and potential mechanisms of miR-485-5p were predicted using bioinformatics technology, and the relationship between miR-485-5p and WNT7B was analyzed by dual luciferase reporter system. The miR-485-5p overexpression (mimic) and inhibitor (inhibitor) were constructed and divided into control, miR-485-5p group and miR-485-5p inhibitor group. After alkaline phosphatase staining (ALP) and alizarin red staining (ARS), osteogenesis-related proteins were detected by Western blot (ALP, BMP-2, Runx2, OPN, OCN); expression of osteogenic proteins was detected by transfection of miR-485-5p inhibitor and WNT7B siRNA into BMSC. Results:The relative expression of miR-485-5p in the osteoporosis group was 7.54±0.49, which was higher than that in the no-osteoporosis group with significant difference ( t=4.11, P<0.001), while the relative expression of WNT7B was significantly lower ( t=3.38, P<0.001), which was negatively correlated with miR-485-5p; bioinformatics analysis found that miR-485-5p targeted 666 genes, miR-485-5p could bind the 3'UTR of WNT7B, and the main mechanism was related to the Wnt/β-catenin signaling pathway; ALP activity and calcium deposition were reduced in the miR-485-5p group compared with the control group, and ALP, BMP-2, Runx2, OPN, OCN, WNT7B and β-catenin proteins were 0.78±0.13, 0.68±0.16, 0.59±0.19, 0.54±0.14, 0.74±0.12, 0.49±0.17, 0.52±0.19, respectively, which were significantly reduced compared with the control group ( t=3.214, P<0.001; t=3.637, P<0.001; t=3.479, P<0.001; t=4.062, P<0.001; t=4.271, P<0.001; t=4.164, P<0.001; t=4.621, P<0.001), and ALP activity, calcium deposition were reduced; ALP, BMP-2, Runx2, OPN, OCN in miR-485-5p inhibition group, WNT7B and β-catenin protein relative expression were 1.29±0.21, 1.24±0.19, 1.16±0.24, 1.31±0.27, 1.45±0.25, 1.05±0.19, 1.41±0.26, respectively, which were significantly higher compared with the control group ( t=3.156, P<0.001; t=3.645, P<0.001; t=3.473, P<0.001; t=3.954, P<0.001; t=4.006, P<0.001; t=3.889, P<0.001; t=4.513, P<0.001). The relative expression of OPN, WNT7B and β-catenin proteins in the miR-485-5p inhibition group were 1.42±0.21, 1.38±0.32, 1.16±0.2.ALP activity was significantly lower in the miR-485-5p inhibition+WNT7Bi group, with lighter ARS staining, fewer bone deposits, and reduced bone-forming related proteins OPN, WNT7B and β-catenin relative expression of 1.08±0.19, 0.71±0.22, and 0.84±0.25, which were all significantly reduced ( t=3.675, P<0.001; t=3.401, P<0.001; t=3.354, P<0.001). Conclusion:MiR-485-5p overexpression slowed down the process of osteogenic differentiation and caused down-regulation of the expression of related proteins, whereas miR-485-5p inhibition promoted osteogenic differentiation and was negatively correlated with WNT7B in the bone tissues of osteoporosis patients. MiR-485-5p binds to the WNT7B mRNA target, which in turn influences the expression of related proteins of WNT7B, and the mechanism of its action is that miR-485-5p targeted to regulate WNT7B-mediated Wnt/β-catenin signalling pathway inhibits BMSC osteogenic differentiation.

Objective:To investigate the efficacy of oblique lumbar interbody fusion (OLIF) combined with percutaneous transforaminal endoscopic decompression (PTED) and posterior pedicle fixation through Wiltse approach in the treatment of lumbar spondylolisthesis accompanied with lumbar spinal stenosis.Methods:From June 2017 to February 2022, 103 patients (50 males and 53 females) of lumbar spondylolisthesis accompanied with lumbar spinal stenosis were performed with OLIF combined with PTED and posterior pedicle fixation. The mean age was 64.1±5.2 years (range, 42-87 years). All involved cases were single-segment and included 83 cases of L 4, 5, 17 cases of L 3, 4, and 3 cases of L 2, 3. Among them, 94 cases were performed for the first time, and other 9 were revision surgery treated by posterior lumbar laminectomy previously. The visual analog scale (VAS) was used to evaluate the low back pain and leg pain, and the Oswestry disability index (ODI) was used to evaluate the lumbar function. The VAS and ODI scores were recorded respectively before the operation, at discharge, 1, 3, 6 months after the operation and at the last follow-up. Macnab criteria was used to evaluate the clinical efficacy at the last follow-up. At the same time, imaging measurements were conducted, including the anterior and posterior disc height, segmental lordotic angle, percentage of slip on lateral X-ray film and the vertebral canal area on axial MRI before and after surgery. Results:All of 103 patients were successfully operated in one stage with an average operation time of 177.7±21.5 min (range, 155-220 min), and an average intraoperative blood loss of 55.9±18.3 ml (range, 30-150 ml). The mean follow-up time were 15.1±2.6 months (range, 6-36 months). There were significant differences in both VAS scores of back and leg and ODI scores at each postoperative time point when compared with preoperative ( F=508.25, F=1524.82, F=1148.68, P<0.001). Macnab criteria of the last follow-up was evaluated as follow: excellent in 85 cases, good in 14, fair in 4, and the excellent and good rate was 96.1%. The radiographic results showed the mean immediate postoperative anterior disc height, posterior disc height, segmental lordotic angle, percentage of slip and axial area of the vertebral canal were 15.23±2.97 mm, 9.32±2.31 mm, 14.36°±4.18°, 3.89%±3.11%, 113.37±47.27 mm 2, and thus all of those increased significantly compared to the mean preoperative 11.93±3.17 mm, 7.21±2.03 mm, 6.15°±3.99°, 23.66%±7.79%, 57.63±28.91 mm 2, respectively ( t=7.84, t=7.07, t=14.91, t=27.62, t=9.68, P<0.001). All cases achieved bony fusion during 6-12 months after operation. The incidence of surgery-related complications was 10.7% (11/103). There were 3 cases of end plate fracture and 2 cases of dural injury, which had no complaint after operation. There was 1 case of pedicle screw entering into the spinal canal by mistake, and the symptoms of nerve damage appeared after operation. After 1 year it basically returned to normal. There were 2 cases of thigh numbness and 1 case of psoas major weakness after operation, all of which relieved after 4 weeks. There was 1 case continuous pain of abdominal incision after surgery. There was 1 case of cage subsidence at the last follow-up. Conclusion:OLIF combined with PTED and posterior pedicle fixation through Wiltse approach is a minimally invasive surgical method for the treatment of lumbar spondylolisthesis accompanied with lumbar spinal stenosis. With the combined minimally invasive techniques, the decompression, fusion and fixation of the lumbar spine can be fulfilled perfectly. It has the advantages of minimally invasive, good clical outcome, few complications and rapid rehabilitation.

Objective:To explore the effectiveness and safety of robot-aided percutaneous anterior column screw combined with posterior plate fixtation treatment for transverse acetabular fractures with posterior wall.Methods:A retrospective analysis was conducted on the data of 13 patients with transverse acetabular fractures and posterior wall fractures treated by robot-aided percutaneous anterior column screws combined with posterior plate in Tianjin Hospital from May 2016 to May 2021. There were 9 males and 4 females, aged 49.1±8.5 years (range, 25-65 years), 9 cases of vehicle accidents, 2 cases of falling injuries, 2 cases of impact injuries, 7 cases of combined posterior hip dislocations, and 1 case of sciatic nerve injury. Apply Kocher-Langenbeck approach for reduction and fixation of the posterior wall and the posterior column and indirect reduction of the anterior column. Use robot navigation for percutaneous anterior column screw fixation, and record the time of inserting anterior column screws, incision length, and complications. The quality of fracture reduction was evaluated using Matta imaging, and the degree of ectopic ossification was evaluated using Brooker classification. The Matta modified Postel Merle D'Aobigne score was used to evaluate the function at 3, 6 months after surgery and at the last follow-up.Results:All 13 patients successfully completed the surgery. The insertion time of the anterior column screw was 19.4±4.0 min (range, 17-23 min), and the incision length was 8.0±1.4 mm (range, 6-10 mm). Postoperative imaging examination showed that all anterior column screws were located within the bone canal, with a screw length of 108.3±11.2 mm (range, 90-130 mm), and no complications such as nerve or vascular injury or incision infection occurred. All 13 patients were followed up for a period of 12-36 months, with an average of 18.6 months; All fractures healed, with a healing time of 2-6 months, average 3.4 months. According to the Matta imaging evaluation method, 11 of 13 patients had anatomical reduction of fractures, and 2 were evaluated as incomplete reduction due to a 1-2 mm gap in the anterior column. The anatomical reduction rate was 84%. At postoperative 3, 6 months and the last follow-up, the modified Postel Merle D'Aobigne scores were 13.4±1.1, 15.8±1.5, and 17.0±1.7, respectively, with statistically significant differences ( F=7.78, P=0.007). The difference between the last follow-up and postoperative 3 months was statistically significant ( P=0.002), and there was no statistically significant difference compared to postoperative 6 months ( P=0.222). At the last follow-up, 8 cases were excellent, 4 cases were good, and 1 case was fair, with an excellent and good rate of 92%. There was no occurrence of ectopic ossification, traumatic arthritis, or necrosis of the femoral head. Conclusion:Robot-aided percutaneous anterior column screw combined with posterior plate treatment for transverse acetabular fractures with posterior wall is safe and effective, and is worthy of clinical promotion.

Objective    To investigate the clinical safety and feasibility of thoracic sympathectomy in the treatment of palmar hyperhidrosis based on ambulatory surgery. Methods    A retrospective analysis of 74 patients who underwent thoracoscopic sympathectomy in the Department of Thoracic Surgery of the First People's Hospital of Yunnan Province from January 2017 to April 2021 was performed, including 35 males and 39 females aged 12-38 (21.32±4.13) years. Patients were divided into two groups according to different treatments. There were 34 patients in a control group (adopting traditional surgery), and 40 patients in an observation group (adopting ambulatory surgery). The clinical effects of the two groups were compared. Results    No massive bleeding, conversion to thoracotomy, postoperative pneumo-thorax or severe pneumonia occured in all patients. Univariate analysis of intraoperative indexes showed that the two groups had no statistical difference in total hospitalization cost, operation time, anesthesia time or postoperative waiting time (P>0.05). The amount of intraoperative blood loss in the observation group was less than that in the control group (P<0.05). The time of postoperative out of bed and recovery of walking capacity and the incidence of electrolyte disturbance in the observation group were shorter or lower than those in the control group (P<0.05). There was no statistical difference in white blood count, neutrophils count or postoperative 24 h pulse oxygen saturation fluctuation peak between the two groups (P>0.05). Conclusion    Based on the optimized diagnosis and treatment model, thoraco-scopic sympathectomy with laryngeal mask airway which is performed during ambulatory surgery, is feasible and worth popularizing in thoracic surgery.
