OBJECTIVE: To compare the effectiveness of posterior axillary edge approach and arthroscopic assisted reduction in the treatment of Ideberg type Ⅰ and Ⅱ glenoid fracture of the scapula. METHODS: The clinical data of 26 patients with fresh Ideberg type Ⅰ and Ⅱ scapular fractures admitted between June 2021 and September 2024 who met the selection criteria were analyzed retrospectively. The patients were divided into two groups according to different treatment methods. Ten cases in the posterior axillary edge group were fixed by open reduction plate through the posterior axillary edge approach, and 16 cases in the arthroscopy group were treated with suture anchor fixation under arthroscopy. There was no significant difference in baseline data between the two groups ( P>0.05), such as gender, age, surgical side, Ideberg type, cause of injury, time from injury to operation, rotator cuff injury, and superior labrum anterior posterior (SLAP) injury, etc. The operation time and fracture healing time were recorded and compared between the two groups, and the shoulder pain was evaluated by visual analogue scale (VAS) score at 1 week, 1 month, and 3 months after operation. At 3 and 6 months after operation, the range of motion of shoulder joint in anteflexion, abduction, external rotation, internal rotation, and backward extension was evaluated, the upper limb dysfunction was evaluated by the Disability Assessment Scale of Arm, Shoulder, and Hand (DASH), and the shoulder joint function was evaluated by the Constant-Murley score. The differences between 6 months and 3 months after operation (changes) were statistically analyzed. RESULTS: Patients in both groups were followed up 11-13 months, with an average of 12.5 months. The operation time and fracture healing time in the posterior axillary edge group were significantly shorter than those in the arthroscopy group ( P<0.05). There was no complication such as wound infection, vascular and nerve injury, loss of reduction, bone nonunion, or glenohumeral instability in both groups. At 1 week after operation, the VAS score in the posterior axillary edge group was significantly higher than that in the arthroscopy group ( P<0.05); there was no significant difference in the VAS score between the two groups at 1 and 3 months after operation ( P>0.05). At 6 months after operation, the changes of shoulder joint in anteflexion, internal rotation range of motion and DASH scores in the posterior axillary edge group were significantly lower than those in the arthroscopy group ( P<0.05), while the changes of abduction, external rotation, backward extension range of motion and Constant-Murley scores were not significantly different between the two groups ( P>0.05). CONCLUSION For Ideberg type Ⅰ and Ⅱ glenoid fracture of the scapula, the posterior axillary edge approach for internal fixation has a short operation time, fast fracture healing, and is beneficial for early functional recovery; arthroscopic assisted reduction has minimal trauma and can handle joint injuries simultaneously. Both surgical procedures are safe and effective, and individualized selection should be made based on soft tissue conditions and combined injuries.

Background and Aims:Portal hypertensive colopathy(PHC)is a common complication of portal hypertension in patients with liver cirrhosis.It may lead to gastrointestinal bleeding,yet its underlying pathogenesis remains unclear,and systematic research in China is limited.This study aimed to analyze the colonoscopic features in cirrhotic patients and to explore their associations with relevant clinical factors.Methods:A retrospective analysis was conducted on 99 cirrhotic patients who underwent colonoscopy at Xingtai People's Hospital between July 2020 and December 2024.Colonoscopy,gastroscopy,and clinical data were reviewed.Differences between patients with PHC and those without were compared in terms of sex,Child-Pugh classification,platelet count,presence of ascites,and hepatic encephalopathy.Multivariate logistic regression was used to identify independent risk factors for PHC.Additionally,colorectal lesion detection rates were compared with those of a contemporaneous cohort of 444 participants undergoing national colorectal cancer(CRC)screening at the same center.Results:Among the 105 patients with cirrhosis,the detection rates of PHC,adenomatous polyps,and CRC were 32.32%,28.28%,and 3.03%,respectively,while only 37.37%had no abnormal findings.No serious colonoscopy-related complications were observed.The proportion of males in the PHC group was significantly higher than in the non-PHC group(78.13%vs.50.75%,P=0.009).The PHC group also showed significantly higher rates of Child-Pugh class B/C,and lower platelet count(all P<0.05).There was no statistically significant difference in the incidence of ascites and hepatic encephalopathy between the two groups(P>0.05).Multivariate analysis identified that male gender(OR=3.307,95%CI=1.219-8.971)and Child-Pugh class B/C(OR=2.867,95%CI=1.046-7.861)were independent risk factors for PHC.Compared to the CRC screening cohort,cirrhotic patients had a similar adenoma detection rate(28.28%vs.25.00%,P=0.499),and a slightly higher colorectal cancer detection rate that did not reach statistical significance(3.03%vs.0.68%,P=0.135).Conclusion:Colonoscopy revealed a high rate of abnormalities in cirrhotic patients,with PHC and adenomatous polyps being the most common findings.Routine colonoscopy is recommended for cirrhotic patients without contraindications,especially males,and patients with Child-Pugh class B/C,to facilitate early detection of PHC and precancerous lesions,thereby reducing the risk of lower gastrointestinal bleeding and missed diagnoses of malignancy.

Objective:To analyze the application value of autophagy related molecular markers in placenta tissue in predicting fetal growth restriction in pregnant women with preeclampsia.Methods:A total of 46 pregnant women admitted to Changsha Hospital for Maternal and Child Health Care from January 2021 to August 2023 were collected. A cross-sectional study was conducted, and they were divided into a normal delivery group (control group, 23 cases) and an observation group with preeclampsia combined with fetal growth restriction (observation group, 23 cases) based on pregnancy outcomes. Transmission electron microscopy was used to observe the occurrence of autophagic vesicles in trophoblast cells in the placental tissue of both groups; The expression of Beclin-1, LC3, and P62 in placental tissues of two groups was detected by immunohistochemistry, real-time fluorescence quantitative polymerase chain reaction (qRT-PCR), and Western blot.Results:The transmission electron microscopy results showed that the presence of autophagic vesicles could be observed in the placental trophoblast cells of both the control group and the observation group, but the number of autophagic vesicles in the trophoblast cells of the observation group was higher than that in the control group ( P<0.05). The immunohistochemical results showed that the colorimetric values of Beclin-1 and LC3 in the placental tissue sections of the observation group were higher than those of the control group (all P<0.001), while the colorimetric values of p62 were lower than those of the control group ( P<0.001). The qRT-PCR and Western blot results showed that the mRNA and protein expression levels of Beclin-1 and LC3 in the observation group were significantly higher than those in the control group (all P<0.001), while the expression levels of p62 mRNA and protein were lower than those in the control group (all P<0.001). Conclusions:The autophagy activity of placental tissue trophoblasts in patients with preeclampsia combined with fetal growth restriction is enhanced, indicating a close correlation between elevated autophagy levels and the occurrence of preeclampsia combined with fetal growth restriction. Excessive autophagy may be involved in the occurrence of preeclampsia combined with fetal growth restriction.

Objective:To investigate the factors influencing postpartum depression (PPD) in elderly multipara undergoing repeat cesarean section.Methods:A convenience sampling method was used to select 160 elderly multipara who underwent repeat cesarean section and completed follow-up at the Department of Obstetrics, First Affiliated Hospital of Zhengzhou University, from June 2021 to June 2023. The Edinburgh Postnatal Depression Scale (EPDS) was employed to assess PPD incidence, classifying participants into PPD and non-PPD groups. Binary Logistic regression analysis was conducted to identify factors influencing PPD.Results:The incidence of PPD among the 160 elderly multipara was 33.13%. Binary Logistic regression analysis indicated that monthly household income, postpartum sleep disturbances, and newborn weight were influencing factors for PPD in elderly multipara undergoing repeat cesarean section.Conclusions:Monthly household income, postpartum sleep disturbances, and newborn weight are significant factors influencing the occurrence of PPD in elderly multipara undergoing repeat cesarean section.

Tumor-associated macrophage promotes the progression of glioblastoma (GBM) by infiltrating into tumor tissue, yet its mechanism has not been fully elucidated.This paper aimed to investigate the mechanism of M2 macrophages in affecting the migratory capacity of GBM via secreting exosomes.Ultracentrifugation was used to extract exosomes; RNA sequencing was carried out to screen differentially expressed miRNAs; target prediction database was used to predict the possible target proteins of miRNA; Dual-luciferase reporter assay was performed to verify the interaction between miRNA and target genes; and the proliferation ability of tumor cells was detected by subcutaneous xenograft model in nude mice.Results showed that tumor-related macrophages were mainly M2 macrophages, and that exosomes secreted by M2 macrophages could promote the migration of glioma cells.Meanwhile, exosomes secreted by M2 macrophages transported miR-1260b and affected the migration of glioma cells through directly targeted AJAP1, suggesting that exosomes secreted by macrophages could affect the migration ability of GBM through transporting miR-1260b.

Objective    To investigate the effect of simvastatin and mechanical pretreatment on intimal hyperplasia of venous graft and its mechanism. Methods    Twelve New Zealand rabbits were selected and randomly divided into 4 groups: a blank control group, a simvastatin topical treatment group, a mechanical precondition group and a combined group (n=3 in each group). Ultrasound was used to evaluate the changes of graft wall and blood flow velocity in the graft, and pathological section was used to evaluate the intimal hyperplasia. Human umbilical cord endodermal cells were cultured in vitro. A simvastatin group and a solvent control group were set to detect YAP phosphorylation, downstream target gene expression and cell proliferation. Results    Vascular ultrasound showed that except the simvastatin topical treatment group, the flow velocity in vein grafts in the other three groups significantly increased 21 days after surgery compared with 7 days after surgery (P<0.01). Pathological sections showed that the thickness of new intima in the simvastatin topical treatment group, mechanical precondition group, combined group and blank control group were 45.56±4.11 μm, 201.28±16.71 μm, 143.57±7.82 μm, 249.45±13.33 μm, respectively, and there were statistical differences compared with the blank control group (P<0.05). In vitro results showed that compared with the solvent control group, cell death was observed in high concentration simvastatin (5 mmol/L) group, cell proliferation was inhibited in low concentration simvastatin (2.5 mmol/L) group (P<0.05), the expression of YAP protein in the simvastatin group was unchanged, but the expression of phosphorylated YAP protein significantly increased (P<0.05), and the expression of downstream target gene ccn1 was down-regulated (P<0.001). Conclusion    Intravascular local application of simvastatin and mechanical preconditioning alone or in combination can inhibit intimal hyperplasia of venous graft. High concentration of simvastatin has cytotoxicity, while low concentration of simvastatin has inhibitory effect on cell proliferation. Simvastatin can inhibit the formation of new intima by inhibiting the entry of YAP into the nucleus and reducing the transcription of cell proliferation-related target gene ccn1.

Objective     To summarize the characteristics of children diagnosed with secondary subaortic stenosis after the surgical closure for ventricular septal defect and explore its potential mechanism. Methods     We retrospectively collected patients aged from 0 to 18 years, who underwent ventricular septal defect closure and developed secondary subaortic stenosis, and subsequently received surgical repair from 2008 to 2019 in Fuwai Hospital. Their surgical details, morphological features of the subaortic stenosis, and the follow-up information were analyzed. Results     Six patients, including 2 females and 4 males, underwent the primary ventricular septal defect closure at the median age of 9 months (ranging from 1 month to 3 years). After the first surgery, patients were diagnosed with secondary subaortic stenosis after 2.9 years (ranging from 1 to 137 months). Among them, 2 patients underwent the second surgery immediately after diagnosis, and the other 4 patients waited 1.2 years (ranging from 6 to 45 months) for the second surgery. The most common type of the secondary subaortic stenosis after ventricular septal defect closure was discrete membrane, which located underneath the aortic valve and circles as a ring. In some patients, subaortic membrane grew along with the ventricular septal defect closure patch. During the median follow-up of 8.1 years (ranging from 7.3 to 8.9 years) after the sencond surgery, all patients recovered well without any recurrence of left ventricular outflow tract obstruction. Conclusion     Regular and persistent follow-up after ventricular septal defect closure combining with or without other cardiac malformation is the best way to diagnose left ventricular outflow tract obstruction in an early stage and stop the progression of aortic valve regurgitation.

ObjectiveTo explore the effect of hip neuromuscular training on reducing the risk of anterior cruciate ligament (ACL) injury in female soccer players. MethodsFrom March to May, 2022, 39 female soccer players from Xi'an Physical Education University were randomly divided into control group (n = 19) and experimental group (n = 20). On the basis of daily training, the control group received sham intervention, and the experimental group received hip neuromuscular training, for six weeks. Before and after training, they were measured dynamic knee valgus (DKV) angle and assessed with Landing Error Score System (LESS); while they were also measured the maximal voluntary isometric contraction (MVIC) and root mean square (RMS) of electromyography as single leg landing of gluteus medius and gluteus maximus. ResultsAll the indexes varied little after training in the control group (|t| < 1.178, P > 0.05), while the indexes improved in the experimental group (|t| > 2.288, P < 0.05), except sagittal score of LESS; and all the indexes improved more in the experimental group than in the control group (|t| > 2.609, P < 0.05), except sagittal score of LESS and MVIC of gluteus maximus. ConclusionHip neuromuscular training can reduce the risk of ACL injury in female soccer players.
