ObjectiveTo investigate the regulatory effect of icariin （ICA） on transforming growth factor-β₁ （TGF-β₁）/Smad pathway in bone microvascular endothelial cells （BMECs） and the effect on autophagy in BMECs. MethodsBMECs were isolated and cultured， and the cell types were identified by immunofluorescence. Cells were divided into the control group， model group （0.1 g·L^-1 methyl prednisolone）， ICA group （0.1 g·L^-1 methyl prednisolone +1×10^-5 mol·L^-1 ICA）， and TGF-β inhibitor group （0.1 g·L^-1 methyl prednisolone +1×10^-5 mol·L^-1 ICA +1×10^-5 mol·L^-1 LY2157299）. Transmission electron microscopy was used to observe the ultrastructure and autophagosome number of BMECs. Autophagy double-standard adenovirus was used to monitor the confocal autophagy flow generation of each cell. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to detect the gene and protein expression of autophagy in the TGF-β₁/ Smad pathway. ResultsAfter cell separation culture， platelet endothelial cell adhesion molecule （CD31） and von willebrand factor （vWF） immunofluorescence identified BMECs. Transmission electron microscopy showed that the cell membrane was damaged， and the nucleus was pyknotic and broken in the model group. Compared with the model group， the ICA group had complete cell membranes， clear structures， with autophagy-lysosome sparsely distributed. The confocal photo showed that BMECs had autophagosomes and autophagy-lysosomes， and the autophagy expression of the ICA group was similar to that of the blank group. Compared with the blank group， in the model group and the LY2157299 group， autophagosomes and autophagy-lysosomes were barely seen in the autophagy flow. Compared with the blank group， the mRNA and protein expressions of autophagy effector protein 1 （Beclin1） and microtubule-associated protein 1 light chain 3B （LC3B） in the model group were significantly decreased （P<0.01）， and those of ubiquitin-binding protein （p62） were significantly increased （P<0.01）. The mRNA expression of TGF-β₁， Smad homolog 2 （Smad2）， and Smad homolog 3 （Smad3） decreased （P<0.05， P<0.01）. The protein expressions of TGF-β₁， p-Smad2， and p-Smad3 were significantly decreased （P<0.01）. Compared with those of the model group， the mRNA and protein expression of Beclin1 and LC3B in BMECs of the ICA group increased （P<0.01）， and those of p62 significantly reduced （P<0.01）. The mRNA expression of TGF-β₁， Smad2， and Smad3 increased significantly （P<0.01）. The protein expression of TGF-β₁， p-Smad2， and p-Smad3 increased significantly （P<0.01）. Compared with those in the model group， the mRNA and protein expressions of Beclin1， LC3B， and p62 in the inhibitor group were not statistically significant. The expression of key genes and proteins of the TGF-β₁ pathway in the inhibitor group was not statistically significant. ConclusionICA can promote glucocorticoid-induced autophagy expression of BMECs， and its mechanism may be related to activating the TGF-β₁/Smad signaling pathway.

ObjectiveThe study aims to investigate the intervention effect of modified Xiangsha Liujunzitang （M-XSLJZ） on intestinal-derived lipopolysaccharide （LPS）-activated Kupffer cell inflammation in rats with hyperlipidemia spleen deficiency syndrome. MethodsSeventy male SD rats were randomly divided into seven groups （n=10）： blank control （CON）， high-fat diet without spleen deficiency （HFD）， high-fat diet with spleen deficiency （SD-HFD）， M-XSLJZ low-， medium-， and high-dose groups （XS-L， XS-M， XS-H）， and western medicine control （R）. Spleen deficiency was induced in SD-HFD， XS-L， XS-M， XS-H， and R groups via irregular diet combined with exhaustive swimming for 15 days. The CON group received a standard diet， while other groups were fed a high-fat diet for 10 weeks to establish the hyperlipidemia model. After successful modeling， rats were treated for 8 weeks： M-XSLJZ was administered at 3.51， 7.02， 14.04 g·kg^-1 in XS-L， XS-M， and XS-H groups， respectively. The R group received 9×10^-4 g·kg^-1 of a reference drug. D-xylose excretion rate was measured by the phloroglucinol method. Blood lipids were assessed using an automated biochemical analyzer. Hematoxylin-eosin （HE） staining was used to evaluate the pathological conditions of the liver， and oil red O staining was used to observe the lipid deposition in the liver. The levels of LPS， portal vein serum LPS， LPS-binding protein （LBP）， serum interleukin-6 （IL-6）， IL-1β， and tumor necrosis factor-α （TNF-α） were detected by enzyme-linked immunosorbent assay （ELISA）. Immunofluorescence was used to evaluate CD86 expression and CD68/TLR4 co-localization in the liver. Protein levels of TLR4， MyD88， NF-κB p65， and p-NF-κB p65 in Kupffer cells were analyzed via Western blot automated protein analysis. Hepatic IL-6， TNF-α， and IL-1β mRNA and protein levels were measured using Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot. ResultsCompared with the CON group， the SD-HFD group showed a decrease in D-xylose excretion （P<0.01）. TC， TG， HDL-C， and LDL-C increased （P<0.05， P<0.01）. A large number of hepatic lipid vacuoles and orange-red lipid droplet deposition appeared in the liver. Ileal LPS， portal LPS， and LBP increased （P<0.05， P<0.01）. The levels of serum IL-6， TNF-α， and IL-1β increased （P<0.01）. The expression of CD86 was upregulated （P<0.01）， and the co-expression of CD68 and TLR4 was enhanced. The protein levels of TLR4， MyD88， and p-p65 in Kupffer cells increased （P<0.01）. The mRNA and protein levels of IL-6， TNF-α， and IL-1β increased （P<0.05， P<0.01）. Compared with the HFD group， the SD-HFD group exhibited decreased D-xylose excretion （P<0.01）， higher HDL-C， LDL-C （P<0.05）， increased portal LBP and LPS （P<0.05）， increased serum IL-6 and TNF-α （P<0.01）， upregulated CD86 （P<0.01）， enhanced CD68/TLR4 co-expression， and higher TNF-α mRNA/protein （P<0.05）. Compared with the SD-HFD group， all M-XSLJZ treatment groups showed reduced TC， TG， and LDL-C （P<0.05， P<0.01）. XS-H and R groups displayed improved hepatic lipid deposition. XS-H and R groups had lower ileal LPS， portal LPS， and LBP levels （P<0.05， P<0.01）. All M-XSLJZ treatment groups exhibited reduced serum IL-6， IL-1β， and TNF-α （P<0.01）. The XS-H group showed downregulated CD86 （P<0.01） and weakened CD68/TLR4 co-expression. The XS-H group had reduced TLR4， MyD88， and p-NF-κB p65 in Kupffer cells （P<0.01）. XS-H and R groups showed lower IL-6， TNF-α， and IL-1β mRNA/protein （P<0.05， P<0.01）. ConclusionM-XSLJZ may exert its lipid-lowering effects by inhibiting intestinal-derived LPS and alleviating Kupffer cell inflammation in the liver.

Objective To analyze the pathogenic bacteria and drug resistance of peritoneal dialysis-associated peritonitis(PDAP),and provide a clinical reference for the rational use of antibiotics.Methods The demographic data of PDAP patients admitted to the peritoneal dialysis(PD)Center of the First Affiliated Hospital of Soochow University from July 1,2015 to December 30,2021 were collected,and the pathogens,drug resistance and prognosis were retrospectively analyzed.Results A total of 150 episodes of PDAP occurred in 92 patients.The positive rate of PD fluid culture was 61.33％,including 65 cases(70.65％)of Gram-positive(G+)bacteria,mainly Staphylococcus and Streptococcus.Gram-negative(G-)bacteria were in 16 cases(17.39％),mainly Escherichia coli and Enterobacter cloacae.There were 11 cases(11.96％)of multiple infections,including 5 cases of combined fungal infection.From 2016 to 2021,the incidence of G+bacteria-related PDAP decreased from 14 to 8 cases.G+strains were resistant to methicillin(35.00％),and were sensitive to linezolid(100.00％),teicoplanin(100.00％)and rifampicin(100.00％).The sensitivity rate to vancomycin was 98.59％.G-strains were sensitive to ceftazidime(86.36％),ceftizoxime(88.89％)and amikacin(100.00％).The MIC of vancomycin against Staphylococcus showed an upward trend in 2019-2021.The overall cure rate of PDAP was 81.33％in patients who responded to antibiotic treatment,and the cure rate of G+bacteria was higher than that of multiple infections(89.23％vs.36.36％,P＜0.01).The outcome of patients with multiple infections,especially those with concurrent fungal infection was poor.Conclusion The incidence of PDAP in the PD center has shown a decreasing trend in recent years.G+bacteria are still the main pathogenic bacteria causing PDAP,and they are highly resistant to methicillin,so vancomycin should be used as empirical therapy.For G-bacteria,cefotaxime and amikacin can be chosen as empirical therapy.There is a drift in the MIC values of vancomycin against Staphylococcus in the study period,so it is necessary to monitor the MIC of vancomycin against Staphylococcus and its changing trend.

Objective To explore the mechanism of modified Xiangsha Liujunzi Decoction in regulating apolipoproteinA-Ⅰ (apoA-Ⅰ),improving endoplasmic reticulum stress,regulating glucose and lipid metabolism,and preventing and treating dyslipidemia in mice. Methods Wild-type (WT) C57BL/6J mice were randomly divided into the WT,WT+high-fat diet(HFD),and WT+HFD+Xiangsha Liujunzi Decoction(XSLJZ) groups according to the random number table method. ApoA-Ⅰ-/-mice were randomly divided into the apoA-Ⅰ-/-,apoA-Ⅰ-/-+HFD,and apoA-Ⅰ-/-+HFD+XSLJZ groups (n=10) according to the random number table method. D12492 was used for HFD feeding to establish a hyperlipidemic mouse model. Modified XSLJZ (23.66g/kg) was administered daily by gavage from the ninth week. Serum and liver tissue were collected for testing after 4 weeks. An automatic biochemical analyzer was used to detect blood lipid levels;an enzyme-linked immunosorbent assay was used to detect serum fasting blood glucose (FBG) and insulin (INS) levels,and the INS resistance index (HOMA-IR) was calculated. Hematoxylin and eosin staining was used to observe the pathological changes in the liver. Oil red O staining was used to observe the lipid deposition in the liver. TG levels in liver tissue were detected using the microplate method. Real-time PCR was used to detect apoA-Ⅰ,glucose-regulated proteins (GRP78),sterol regulatory element binding protein-1c (SREBP-1c),acetyl CoA carboxylase 1 (ACC1),and fatty acid synthase (FASN) mRNA expression levels in liver tissue. The WES fully automated protein expression analysis system was used to detect apoA-Ⅰ,GRP78,inositol-requiring enzyme 1 (IRE1),p-IRE1,c-Jun N-terminal kinase (JNK),p-JNK,insulin receptor substrate (IRS1),p-IRS1,protein kinase B (Akt),p-Akt,SREBP-1c,ACC1,and FASN protein expression levels in liver tissue. Results Compared to the WT group,the WT+HFD group showed a significant increase in serum lipids,FBG,INS levels,and the HOMA-IR index (P<0.05).

Objective:To compare the clinical efficacy of the anterior approach versus the posterolateral approach for total hip arthroplasty (THA) in treating residual high dislocation secondary to pyogenic hip arthritis, and to investigate the benefits of proximal femoral reconstruction osteotomy.Methods:A retrospective study was conducted on 45 patients who underwent THA combined with proximal femoral reconstruction osteotomy for high dislocation secondary to pyogenic hip arthritis at the First Affiliated Hospital of the University of Science and Technology of China from January 2017 to September 2022. Patients were categorized into two groups based on the surgical approach: 14 in the anterior approach group and 31 in the posterolateral approach group. We analyzed surgical duration, intraoperative blood loss, postoperative visual analogue scale (VAS) scores for lateral knee pain after knee extension, postoperative limb lengthening, Harris hip scores, and complications. Radiographic assessments included anteversion and abduction angles of the acetabular cup, hip abductor muscle lever arm, hip-knee-ankle (HKA) angle of the affected side, osteotomy site bone healing rate, and prosthesis loosening.Results:The average follow-up period was 3.6±1.8 years (range, 1.0-6.7 years). The anterior approach group had a significantly longer surgical duration (141.4±21.0 min) compared to the posterolateral approach group (121.3±23.1 min). Intraoperative blood loss was significantly less in the anterior approach group (425.2±80.2 ml) compared to the posterolateral approach group (535.1±96.3 ml). The difference was statistically significant ( P<0.05). The VAS score for lateral knee pain after knee extension was significantly lower in the anterior approach group (3.2±0.8) than in the posterolateral approach group (5.7±1.1), the difference was statistically significant ( t=7.300, P<0.001). Postoperative limb lengthening was 5.0±1.5 cm in the anterior approach group and 4.5±1.4 cm in the posterolateral approach group, with no significant difference ( t=1.075, P=0.289). At the final follow-up, the Harris hip score was 86.2±5.0 in the anterior approach group and 82.5±6.8 in the posterolateral approach group, with no significant difference ( t=1.839, P=0.073). The acetabular anteversion angle, abduction angle, and HKA angle in the anterior approach group were 12.9°±5.8°, 42.6°±6.2°, and 179.8°±1.4°, respectively, while in the posterolateral approach group they were 14.5°±7.0°, 44.2°±3.1°, and 178.8°±2.1°, respectively. The differences between the groups were not statistically significant ( P>0.05). The hip abductor muscle lever arm was 5.6±0.7 cm on the surgical side compared to 5.9±0.6 cm on the healthy side, with no significant difference ( t=1.916, P=0.059). All patients achieved bone healing at the osteotomy site by the final follow-up. One patient in the anterior approach group experienced femoral prosthesis subsidence but did not require femoral revision. Two patients in the posterolateral approach group experienced hip dislocation, both of which were managed with intravenous anesthesia and closed reduction. Conclusion:The anterior approach for THA combined with proximal femoral reconstruction osteotomy yields better clinical outcomes compared to the posterolateral approach, including reduced intraoperative blood loss, decreased lateral knee pain, and a lower rate of dislocation. Proximal femoral reconstruction osteotomy effectively restores the hip abductor muscle lever arm with a high rate of osteotomy site healing.

Objective To investigate the expression of long non-coding RNA(lncRNA)small nucleolar RNA host gene(SNHG)25 and microRNA(miR)-497-5p in glioma tissues and their relationship with clinical features and prognosis.Methods A total of 157 glioma patients admitted to the hospital from January 2019 to January 2020 were selected as the glioma group,and 100 patients who underwent surgical treatment due to craniocerebral injury in the same hospital during the same period were selected as the control group.The ex-pression levels of lncRNA SNHG25 and miR-497-5p were detected in glioma tissues and normal brain tissues resected during operation.The patients were followed up for 3 years.The correlation between the expression levels of lncRNA SNHG25 and miR-497-5p was analyzed,and the relationship between the expression level of lncRNA SNHG25 and miR-497-5p and the clinical characteristics and prognosis of patients were analyzed.Re-sults Compared with the control group,the expression level of lncRNA SNHG25 in the glioma group was in-creased(P＜0.05),and the expression level of miR-497-5p was decreased(P＜0.05).Compared with the maximum diameter of tumors＜4 cm,World Health Organization(WHO)central nervous system tumor grade Ⅰ-Ⅱ,the expression level of lncRNA SNHG25 was increased and the expression level of miR-497-5p was decreased in glioma tissues with the maximum diameter of tumors ≥4 cm and WHO central nervous sys-tem tumor grade Ⅲ-Ⅳ(P＜0.05).The expression level of lncRNA SNHG25 in glioma patients was nega-tively correlated with miR-497-5p(r=-0.370,P＜0.05).The cumulative survival rate of lncRNA SNHG25 high expression group was lower than that of lncRNA SNHG25 low expression group(P＜0.05),and the cu-mulative survival rate of miR-497-5p low expression group was lower than that of miR-497-5p high expression group(P＜0.05).Grade Ⅲ-Ⅳ of WHO central nervous system tumor grade and high expression of lncRNA SNHG25 were risk factors for poor prognosis of glioma patients(P＜0.05),while high expression of miR-497-5p was a protective factor(P＜0.05).Conclusion The expression of lncRNA SNHG25 is increased and the expression of miR-497-5p is decreased in glioma tissues,which is related to the maximum diameter of tumor and high WHO central nervous system tumor grade,and can lead to poor prognosis of glioma patients.

Objective:To evaluate the clinical effect of bispherical augment in acetabular defects reconstruction in hip revision.Methods:This is a retrospective case series study. A retrospective analysis of 119 patients (124 hips) patients who underwent hip revision surgery and reconstructed with bispherical augment for acetabular bone defects from January 2019 to December 2023 was performed. There were 57 males (58 hips) and 62 females (66 hips), aged (65.0±11.8) years (range:40 to 102 years). The body mass index was (23.9±3.5) kg/m 2 (range:16.1 to 32.2 kg/m 2). Acetabular bone defects were typed as follows: 2 hips in Paprosky type ⅡA, 29 hips in type ⅡB, 34 hips in type ⅡC, 31 hips in type ⅢA, and 28 hips in type ⅢB, of which 9 patients (9 hips) were combined with pelvic discontinuity. Differences in Harris hip score (HHS) and lower limb discrepancy (LLD) were compared between preoperatively and final follow-up. The height of the hip center of rotation and the horizontal distance from the center of rotation to the teardrop were measured by radiographs before and after surgery, and prothesis stability and the occurrence of postoperative complications were evaluated. Data were compared using the paired sample t test. Results:All patients successfully completed the operation. The operation time was (167.0±53.4) minutes (range:90 to 380 minutes) and the intraoperative bleeding was (345.3±124.2) ml (range:100 to 1 200 ml). The height of the hip center of rotation decreased from (39.7±13.0) mm preoperatively to (21.8±7.1) mm postoperatively and the horizontal distance from the center of rotation to the teardrop increased from (34.0±10.1) mm preoperatively to (38.5±5.9) mm postoperatively, and the differences were statistically significant ( t=15.859, P<0.01; t=5.266, P<0.01). All the patients were followed up for (26.1±15.4) months (range:6 to 60 months). At the last follow-up, HHS improved from (35.2±10.0) points preoperatively to (85.5±9.5) points, and the difference was statistically significant ( t=50.723, P<0.01). LLD decreased from (2.1±1.1) cm preoperatively to (0.5±0.5) cm, and the difference was statistically significant ( t=13.767, P<0.01). All acetabular components were stable and free of displacement on imaging during follow-up. Three patients suffered dislocation and received closed reduction, all prosthesis were in good position during follow-up. No dislocation, loosening, fracture, recurrence of infection and vascular nerve injury occurred in other patients. Conclusion:Bispherical augment can effectively reconstruct acetabular bone defects, restore the hip center of rotation, and improve hip joint function scores at short and mid-term follow-up.

Objective:To compare the effect of modified postauricular transverse incision and traditional vertical incision for microvascular decompression in the treatment of hemifacial spasm.Methods:Prospective study method was used. A total of 116 patients with hemifacial spasm in Handan Central Hospital from January 1, 2019 to January 1, 2020 were selected, and divided into two groups according to the admission order. Both groups underwent microvascular decompression; control group (57 cases) received traditional vertical incision, while treatment group (59 cases) received modified postauricular transverse incision. The brainstem auditory evoked potential (BAEP), pain degree, surgical indicators, facial aesthetic satisfaction and complications were compared between two groups.Results:After treatment, the BAEP of latency, wave interval and wave amplitude in the two groups increased compared with that before treatment, and the BAEP of latency, wave interval and wave amplitude in the treatment group were higher than those in the control group: (1.89 ± 0.15) ms vs. (1.62 ± 0.21) ms, (7.89 ± 0.15) ms vs. (6.25 ± 0.41) ms, (1.79 ± 0.19) ms vs. (1.54 ± 0.11) ms ( P<0.05). After treatment, the visual analogue score (VAS) of patients in the two groups decreased compared with that before treatment, and the VAS of patients in the treatment group was lower than that in the control group: (1.15 ± 0.27) points vs. (2.18 ± 0.24) points ( P<0.05). The operation time, intraoperative bleeding volume and postoperative scar length of patients in the treatment group were less than those in the control group: (60.41 ± 3.81) h vs. (76.87 ± 3.87) h, (30.18 ± 4.19) ml vs. (56.87 ± 4.15) ml and (4.18 ± 1.07) cm vs. (6.87 ± 1.05) cm ( P<0.05). The satisfaction rate of patients in the treatment group was higher than that in the control group: 91.53% (54/59) vs. 71.93% (41/57) ( P<0.05). The complication rate of patients in the treatment group was lower than that in the control group: 5.08% (3/59) vs. 21.05% (12/57) ( P<0.05). Conclusions:Compared with traditional vertical incision, the modified transverse incision for microvascular decompression in the treatment of hemifacial spasm can reduce intraoperative blood loss and postoperative scar area, enhance brainstem auditory evoked potential, and improve facial aesthetics, which is worthy of recommendation.
