Objective To investigate the correlation between the expression of lectin galactoside binding soluble-3 binding protein(LGALS3BP),GTP enzyme activating protein SH3 functional region binding protein 1(G3BP1)and Wnt/β-catenin pathway genes in endometrial cancer(EC)tissues and its clinical prognostic significance.Methods 138 patients with EC treated in Cangzhou Central Hospital from February 2016 to February 2019 were selected.qRT-PCR was used to detect the expression of LGALS3BP mRNA,G3BP1 mRNA and Wnt/β-catenin pathway genes Wnt5a mRNA,β-catenin mRNA and matrix metalloproteinase-9(MMP-9)mRNA in cancer and adjacent tissues.The expression of LGALS3BP protein and G3BP1 protein in cancer and adjacent tissues was detected by immunohistochemistry.Pearson correlation analysis was used to analyze the correlation between LGALS3BP mRNA,G3BP1 mRNA and Wnt/β-catenin pathway genes.Kaplan-Meier curve was used to analyze the effect of LGALS3BP mRNA and G3BP1 mRNA on the survival and prognosis of EC patients.COX regression model was used to analyze the factors affecting the prognosis of EC patients.Results The expression of LGALS3BP mRNA(3.01±0.34),G3BP1 mRNA(2.87±0.33),Wnt5a mRNA(2.29±0.26),β-catenin mRNA(3.25±0.41)and MMP-9 mRNA(2.68±0.36)in EC cancer tissues were higher than those in adjacent tissues(1.10±0.23,1.06±0.24,0.84±0.17,0.88±0.26,0.69±0.17),and the differences were statistically significant(t=52.109～58.719,all P<0.001).The expression of LGALS3BP mRNA and G3BP1 mRNA in EC was positively correlated with the expression of Wnt5a mRNA,β-catenin mRNA and MMP-9 mRNA(r=0.675～0.781,all P<0.001).The expression of LGALS3BP protein(3.54±0.47 vs 0.51±0.16)and G3BP1 protein(2.84±0.44 vs 0.42±0.13)in EC cancer tissues were higher than that in adjacent tissues,and the differences were statistically significant(t=71.692,61.962,all P<0.001).The expression of LGALS3BP mRNA and G3BP1 mRNA in cancer tissues of EC patients with FIGO stage Ⅲ and lymph node metastasis were higher than that of FIGO stage Ⅰ～Ⅱ and no lymph node metastasis,and the differences were statistically significant(t=40.279～557.671,all P<0.001).The 5-year survival rate of LGALS3BP mRNA high expression group was 58.82%(40/68),which was lower than that of low expression group 94.29%(66/70),and the difference was statistically significant(Log-rank χ2=24.970,P<0.001).The 5-year survival rate of G3BP1 mRNA high expression group was 62.12%(41/66),which was lower than that of low expression group 90.28%(65/72),and the difference was statistically significant(Log-rank χ2=15.960,P<0.001).FIGO stage Ⅲ,lymph node metastasis,high expression of LGALS3BP mRNA and high expression of G3BP1 mRNA were risk factors for poor prognosis of EC patients(Wald χ2=7.847～12.054,all P<0.001).Conclusion The expression of LGALS3BP and G3BP1 mRNA is elevated in EC,both of which are associated with Wnt/β-catenin pathway genes,promoting the malignant progression of EC tumors,and are new tumor markers for evaluating the prognosis of EC patients.

Objectives:Coronary slow flow(CSF)has long been regarded as a marker of coronary microvascular dysfunction(CMD).This study aims to evaluate the diagnostic value of CSF for CMD in patients with angina and nonobstructive coronary arteries(ANOCA).Methods:The study data were derived from the ANOCA-CMD prospective cohort study.All enrolled patients underwent coronary angiography and concurrent coronary physiological assessments in the left anterior descending artery using pressure-wire and thermodilution techniques to obtain coronary flow reserve(CFR)and the index of microcirculatory resistance(IMR).Based on the results,CMD was classified into four subtypes:CMD with elevated IMR(IMR≥25),CMD with reduced CFR(CFR<2.5),CMD with either reduced CFR or elevated IMR(CFR<2.5 or IMR≥25),and CMD with both reduced CFR and elevated IMR(CFR<2.5 and IMR≥25).The corrected thrombolysis in myocardial infarction(TIMI)frame count(CTFC)in the left anterior descending artery was calculated from coronary angiography images,with CSF defined as CTFC>27.This study evaluated the correlation between CTFC,CFR,and IMR,and investigated the diagnostic value of CSF for CMD in ANOCA patients.Results:A total of 103 ANOCA patients were enrolled in this study,with a mean age of(64.2±10.6)years,and 53.4％were female.Among them,57 patients(55.3％)were diagnosed with coronary slow flow.Patients with slow flow had higher IMR(P<0.001)and CFR(P=0.041).Similarly,the proportion of CMD with elevated IMR was higher in the slow flow group(P<0.001),while the proportion of CMD with reduced CFR was lower(P=0.044).There was no significant difference between the groups in the proportions of CMD with either reduced CFR or elevated IMR or CMD with both reduced CFR and elevated IMR(all P>0.05).CTFC was positively correlated with hyperemic mean transit time(r=0.424,P<0.001),IMR(r=0.430,P<0.001),and CFR(r=0.211,P=0.032).The area under the curve(AUC)of CTFC for diagnosing CMD with elevated IMR was 0.721(95％CI:0.623-0.819)with an accuracy of 67％(57％,76％),for diagnosing CMD with reduced CFR was 0.610(95％CI:0.499-0.720)with an accuracy of 60％(50％,70％),for diagnosing CMD with either reduced CFR or elevated IMR was 0.549(95％CI:0.425-0.673)with an accuracy of 47％(37％,57％),and for diagnosing CMD with both reduced CFR and elevated IMR was 0.582(95％CI:0.471-0.693)with an accuracy of 47％(37％,57％).Thus,CSF demonstrated limited diagnostic values across all subtypes of CMD.Conclusions:In ANOCA patients,CSF cannot serve as an effective diagnostic marker for CMD.Therefore,in clinical practice,the slow flow phenomenon should not be directly equated with the presence of coronary microvascular dysfunction in ANOCA patients.

Objective:To investigate the necessity of internal fixation of the fibular fracture in the treatment of degree Ⅱ ankle supination-external rotation injury by the Dias-Tachdjian classification in children.Methods:A retrospective study was conducted to analyze the data of 69 children with ankle fracture (degree Ⅱ ankle supination-external rotation injury by the Dias-Tachdjian classification) who had been treated at Department of Orthopedic Trauma, The People's Hospital of Weifang and Department of Pediatric Orthopedics, Tianjin Hospital from January 2015 to October 2021. There were 41 males and 28 females with an age of (10.1±1.4) years, and 37 left and 32 right sides affected. The patients were divided into 2 groups according to whether internal fixation of the fibular fracture was performed. Group A consisted of 21 cases with fibular internal fixation and group B of 48 cases without fibular internal fixation. The preoperative data, operation time and operation expenses were recorded and compared between the 2 groups. At the last follow-up, the anteroposterior and lateral radiographs of bilateral full length lower limbs and ankle joints were taken; the lateral distal tibial angle (LDTA) and the anterior distal tibial angle (ADTA) on the affected side, and the disparity between bilateral ankle tibiotalar angles were measured; ankle function was assessed according to the ankle-hindfoot score of American Association of Foot and Ankle Surgery (AOFAS); the occurrence of premature physeal closure (PPC) was recorded.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (19.5±4.1) months. At the last follow-up, the LDTA on the affected side was 89.6° (87.9°, 90.5°) in group A and 88.6°±1.9° in group B; the ADTA on the affected side was 80.9° (79.0°, 81.4°) in group A and 80.0° (78.6°, 81.2°) in group B; the disparity between bilateral ankle tibiotalar angles was 1.1°±0.5° in group A and 1.2°±0.5° in group B; the AOFAS ankle-hindfoot score was (89.5±5.2) points in group A and 89.0 (87.0, 92.0) points in group B. There was no statistically significant difference between the 2 groups in the above items ( P>0.05). The incidence of PPC was, respectively, 14.3% (3/21) and 14.6% (7/48) in groups A and B, showing no statistically significant difference ( P>0.05). Conclusions:In the treatment of degree Ⅱ ankle supination-external rotation injury in children, internal fixation of the fibular fracture has no significant effect on the imaging angles or the function of the ankle joint. After anatomic reduction of the distal tibia, the fibular fracture can be treated without internal fixation to reduce operational trauma, shorten operation time and reduce operation expenses.

A total of 44 patients with diabetic foot ulcers were treated in the Traumatic Orthopedics Department of Weifang People′s Hospital from January 2019 to December 2022. After debridement of foot ulcers the wounds were soaked in alkaline water of pH 7.5-8.0 (study group, n=22) or covered with vaseline gauze following iodophor disinfection (control group, n=22). The therapeutic effects of the two methods were compared. Four weeks after debridement, the wound area of study group was smaller than that of control group (3.15 (0, 7.60) vs. 6.75 (3.50, 9.32)cm 2, P<0.05), and the proportion of positive wound bacterial culture was lower than that of control group (40.9% (9/22) vs. 72.7% (16/22), P<0.05). At 12 weeks after surgery, there was no statistically significant difference in the wound healing rate between the two groups (72.7% (16/22) vs. 63.6% (14/22)), but the healing time of the study group was significantly shorter than that of the control group ((6.56±2.68) vs. (9.50±3.87) weeks, P<0.05). It is suggested that immersion of weak alkaline solution is helpful to promote wound healing for patients with diabetic foot ulcers after debridement surgery.

Objective:To investigate the clinical effect of fascial sling of flexor-pronator teres origin and anterior subcutaneous transposition of ulnar nerve in the treatment of severe cubital tunnel syndrome.Methods:30 patients with severe cubital tunnel syndrome were prospectively enrolled, who underwent surgical treatment at the Affiliated Hospital of Binzhou Medical University from December 2021 to February 2022. Randomized drawing divided the patients into two groups: the fascial sling group and the anterior subcutaneous transposition group with 15 cases on each group. In the fascial sling group, there were 11 males and 4 females, with an average age of 59 years (range 51-73 years), who underwent fascial suspension after ulnar nerve decompression. In the anterior subcutaneous transposition group, there were 10 males and 5 females, with an average age of 56 years (range 41-72 years), who underwent where the ulnar nerve was subcutaneous transposition after ulnar nerve decompression. The dynamic two-point discrimination and grip strength of the little finger on the affected limb were measured at 6, 12, and 24 months postoperatively. The postoperative improvement between the two groups were compared. Functional assessment and patient satisfaction surveys were conducted and compared at 24 months.Results:Neither groups had incision-related complications. The surgical duration for the fascial sling group was longer than that for the anterior subcutaneous transposition group (46.80±1.86 min and 43.87±2.00 min) with significant difference ( t=4.166, P<0.001). Blood loss during surgery in the fascial sling group was greater than that in the anterior subcutaneous transposition group (3.53±0.52 ml and 2.53±0.52 ml) with significant difference ( t=5.303, P<0.001). No significant difference was found in the improvement of dynamic two-point discrimination of the little finger in the affected limb at 6, 12, and 24 months postoperatively between the fascial sling group and the anterior subcutaneous transposition group (5.87±1.41 mm, 4.27±1.16 mm, 3.13±1.06 mm and 5.73±1.98 mm, 4.40±1.45mm, 3.20±1.15 mm), ( t=0.213, P=0.833; t=-0.277, P=0.784; t=-0.165, P=0.870). There was no significant difference in grip strength improvement in the affected limb at 6 and 12 months postoperatively between the fascial sling group and the anterior subcutaneous transposition group (24.62±4.94 kg, 25.88±4.72 kg and 21.94±3.76 kg, 23.62±4.00kg), ( t=1.448, P=0.159; t=1.404, P=0.171). At 24 months postoperatively, the fascial sling group showed better grip strength improvement compared to the anterior subcutaneous transposition group (27.58±4.92 kg and 23.62±4.00 kg) with significant difference ( t=2.425, P=0.033). The functional assessment revealed that the fascial sling group included 4 excellent, 8 good, and 3 acceptable cases, while the anterior subcutaneous transposition group had 3 excellent, 8 good, and 4 acceptable cases. One case in the fascial sling group was unsatisfied with the improvement in function. Four cases in the anterior subcutaneous transposition group were unsatisfied with functional improvement due to significant discomfort in the surgical area. Conclusion:The fascial sling technique of the flexor-pronator muscle origin yielded better clinical results on postoperative grip strength improvement and patient satisfaction compared to the anterior subcutaneous transposition.

Objective To construct a predictive model of thrombus clearance rate to guide the selection of therapeutic strategies for acute lower extremity venous thromboembolism patients by studying the clinic data of patients who underwent AngioJet mechanical thromboaspiration surgery.Methods By calculating the thrombus clearance rate in 83 VTE patients treated with AngioJet surgery,correlation analysis of clinical data,combined with the characteristic factors in the LASSO regression model,multiple logistic regression analysis was applied to build a prediction model of thrombus clearance rate column line graph,and the accuracy of the prediction model was evaluated using C index,calibration curve and decision curve.Results VTE type was significantly correlated with thrombus clearance rate,and the predictors in the column line plot contained:age,sex,thrombus type,surgical history,tumor history,and smoking history.The model showed great predictive power and high accuracy with a C-index of 0.795(95％CI:0.682 3-0.905 7).Decision curve analysis showed that prediction of thrombus clearance by column line plot for AngioJet procedure was effective when the threshold probability was in the range of 0.02-0.63.Conclusion In the correlation analysis,VTE type was significantly correlated with thrombus clearance.The results of this study showed that the AngioJet thrombus aspiration procedure was able to achieve a high rate of thrombus clearance in men older than 65 years with a history of tumors,a central thrombus type,no history of surgery,and no history of smoking.

[Objective] To explore the characteristics of lifestyle behaviors and mental health status among blood donors in Guangzhou, and to investigate the correlation between donation frequency and these factors. [Methods] A cross-sectional study was conducted among 13 042 whole blood donors from 17 street blood donation sites of Guangzhou Blood Center from May to August 2020. Descriptive analysis was used to describe the characteristics of lifestyle behaviors and mental health status among blood donors in Guangzhou. Ordinal multinomial logistic regression model was used to analyze the correlation between donation frequency and these factors. [Results] It was found that some of 13 042 blood donors had unhealthy habits, such as 6.8% (698/10 214，2 828 missing values) had severe tobacco dependence, 30.6% (3 997/13 042) had low exercise levels, 38.8%（5 056/13 042）had poor sleep quality, and 2.2% (271/12 159，883 missing values) had alcohol dependence. In addition, 2.8% (364/13 042) and 1.3% (172/13 042) of the donors may have moderate to severe depression and anxiety symptoms, respectively. The results of the ordinal multinomial logistic regression model showed that exercise level was significantly negatively correlated with the degree of depression and anxiety among blood donors. With the decrease in exercise level, the possibility of depression and anxiety among donors increased significantly. BMI, household income, education level, marital status, donation frequency, alcohol consumption and smoking had no significant correlation with the mental health status of donors. [Conclusion] Improving the exercise habits of blood donors may help enhance their mental health level. It is recommended that blood station staff strengthen the content of exercise when providing health education to blood donors to maintain a healthy lifestyle. It also suggests that there may be a certain degree of under-diagnosis of mental health problems in the process of health consultation before blood donation, and conducting more comprehensive and effective mental health assessments for blood donors is recommended.
