Objective:To explore the efficacy of percutaneous vertebroplasty (PVP) using the partition injection technique in the treatment of Kümmell’s disease of stages Ⅰ and Ⅱ.Methods:A retrospective study was conducted of the 30 patients with stage Ⅰ or Ⅱ Kümmell’s disease (the partition group) who had been treated by PVP using the partition injection technique at Department of Spinal Surgery, Zhengzhou Orthopedic Hospital from January 2020 to January 2022. The data of another 30 patients who had been treated at the same department and the same period using conventional PVP for stage Ⅰ or Ⅱ Kümmell's disease were selected as the conventional group. In the partition group, there were 13 males and 17 females, with an age of (72.3±10.1) years and disease duration of (3.1±1.5) months. Seventeen thoracic and 13 lumbar vertebrae were affected. In the conventional group, there were 11 males and 19 females, with an age of (75.5±12.7) years and disease duration of (3.5±1.8) months. Eighteen thoracic and 12 lumbar vertebrae were affected. Surgical time, volume of bone cement injected, bone cement leakage, and bone cement distribution were compared between the 2 groups. The heights of the anterior and middle vertebral bodies, kyphotic Cobb angle, visual analog scale (VAS) pain score, and Oswestry disability index (ODI) were assessed postoperatively at 1 day, 6 months, and the last follow-up and compared between the 2 groups.Results:No significant differences were found in the baseline data between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (17.3±3.1) months. There were no significant differences in the surgical time or bone cement leakage between the 2 groups ( P>0.05). The volume of bone cement injected in the partition group was significantly higher [(6.3±1.5) mL] than that in the conventional group [(4.9±1.0) mL] ( P<0.05). Bone cement distribution was significantly better in the partition group than that in the conventional group ( P<0.05). At postoperative 1 day, 6 months, and the last follow-up, the partition group was significantly better than the conventional group in anterior vertebral body height, middle vertebral body height, and kyphotic Cobb angle ( P<0.05). At the 6-month and the last follow-ups, the partition group was also significantly better than the conventional group in VAS pain score and ODI ( P<0.05). Conclusion:In the treatment of Kümmell’s disease of stages Ⅰ and Ⅱ, compared with conventional PVP, PVP using the partition injection technique may lead to better long-term outcomes due to its better bone cement distribution, more adequate cement injection, and better restoration of vertebral body heights and correction of local deformity.

The polymerase 1 and transcript release factor (PTRF)-cytoplasmic phospholipase A2 (cPLA2) phospholipid remodeling pathway facilitates tumor proliferation in glioma. Nevertheless, blockade of this pathway leads to the excessive activation of oncogenic receptors on the plasma membrane and subsequent drug resistance. Here, CD26/dipeptidyl peptidase 4 (DPP4) was identified through screening of CRISPR/Cas9 libraries. Suppressing PTRF-cPLA2 signaling resulted in the activation of the epidermal growth factor receptor (EGFR) pathway through phosphatidylcholine and lysophosphatidylcholine remodeling, which ultimately increased DPP4 transcription. In turn, DPP4 interacted with EGFR and prevented its ubiquitination. Linagliptin, a DPP4 inhibitor, facilitated the degradation of EGFR by blocking its interaction with DPP4. When combined with the cPLA2 inhibitor AACOCF3, it exhibited synergistic effects and led to a decrease in energy metabolism in glioblastoma cells. Subsequent in vivo investigations provided further evidence of a synergistic impact of linagliptin by augmenting the sensitivity of AACOCF3 and strengthening the efficacy of temozolomide. DPP4 serves as a novel target and establishes a constructive feedback loop with EGFR. Linagliptin is a potent inhibitor that promotes EGFR degradation by blocking the DPP4-EGFR interaction. This study presents innovative approaches for treating glioma by combining linagliptin with AACOCF3 and temozolomide.

BACKGROUND:The expression efficiency of recombinant adeno-associated virus serotype 9(rAAV9)carrying the macrophage-specific promoter synthetic promoter 146-C1(SP146-C1)and the exogenous gene vascular endothelial growth factor C(VEGFC)in atherosclerosis is uncertain. OBJECTIVE:To investigate the expression efficiency of rAAV9-SP146-C1-VEGFC in atherosclerotic mice and its effect on lymphangiogenesis. METHODS:Thirty ApoE-/-mice were fed high-fat diet for 12 weeks to establish atherosclerosis models and were randomly divided into six groups,five in each group:7-,14-,21-,28-,and 35-day transfection groups and control group.The mice in the transfection groups were transfected with 5.0×1011 vg rAAV9-SP146-C1-VEGFC by caudal vein injection.In the control group,the mice were injected with the same amount of control virus rAAV9-SP146-C1-Scramble.Animals in the first five groups were killed under anesthesia at 7,14,21,28 and 35 days after transfection,respectively,and those in the control group were killed under anesthesia at 7 days.Serum,femur,tibia,heart and aorta tissue samples were collected and retained in each group.The femur and tibia of mice in each group were used to extract bone marrow-derived macrophages.The gene expression of vascular endothelial growth factor C(VEGFC),vascular endothelial growth factor receptor 3(VEGFR3),Podoplanin and lymphatic vessel endothelial hyaluronan receptor-1(LYVE-1)in bone marrow-derived macrophages and the aorta were detected by RT-qPCR.VEGFC protein expression levels in bone marrow-derived macrophages and the aorta were detected by western blot,serum level of VEGFC was detected by ELISA,and VEGFC expression in the aortic sinus and LYVE-1 expression around the aorta and in the myocardium was detected by immunofluorescence. RESULTS AND CONCLUSION:The serum level of VEGFC,the mRNA expression of VEGFC,VEGFR3,Podoplanin,and LYVE-1 in bone marrow-derived macrophages and the aorta,the protein expression of VEGFC in bone marrow-derived macrophages,and the fluorescence intensity of VEGFC in aortic sinus plaques were significantly increased in the 7-day transfection group compared with the control group(P＜0.05,P＜0.01).Serum VEGFC level of mice transfected with rAAV9-SP146-C1-VEGFC gradually increased with time and began to decrease at 28 days.mRNA levels of VEGFC,VEGFR3,Podoplanin and LYVE-1 in mouse aorta and bone marrow-derived macrophages,VEGFC protein level in bone marrow-derived macrophages,VEGFC fluorescence intensity in aortic sinus plaques,LYVE-1 fluorescence intensity around the aortic sinus and in the myocardium gradually increased with time(P＜0.05).In addition,the mRNA level of LYVE-1 in the aorta and the fluorescence intensity of LYVE-1 around the aortic sinus and in the myocardium were the highest at 28 days(P＜0.05),and gradually decreased(P＜0.05).The expression of the other indicators reached the peak at 21 days.To conclude,rAAV9-SP146-C1-VEGFC could effectively transfect bone marrow-derived macrophages and promote lymphatic hyperplasia in atherosclerotic mice.

Objective:To analyze the prognostic value of the coagulation index in stereotactic radio surgery(SRS)for patients with non-small cell lung cancer(NSCLC)and brain metastases(BMS).Methods:We retrospectively analyzed clinical data from 512 patients diagnosed with NSCLC and BMS,who were treated with SRS at Tianjin Huanhu Hospital from October 2015 to September 2018.The overall survival(OS)and progression-free survival(PFS)rates were analyzed.The Cox model was employed to examine prognostic factors.Subsequently,the receiver operating characteristic(ROC)curve was constructed based on multi-factor analysis usin the Cox model.The area under the ROC curve(AUC)was used to assess the prognostic value of coagulation indexes in patients with NSCLC and BMS who underwent SRS.Results:In 1,2,3,and 4 years,PFS rates were 79.9%,69.9%,56.6%,and 43.2%,respectively,and OS rates were 93.4%,83.2%,69.9%,and 57.6%,respectively.Smoking and average fibrinogen(Fib)levels,prothrombin time(PT),and D-dimer(D-D)levels were correlated with a longer PFS(P<0.05).Av-erage activated partial thromboplastin time(APTT),Fib,and D-D levels were correlated with a longer OS(P<0.05).Smoking and mean Fib and D-D levels were significantly correlated with a longer PFS(P<0.05),while The average levels of Fib and D-D are each significantly associated with longer OS rates(P<0.05).The combined detection of Fib and D-D in predicting the prognosis of NSCLC patients with brain metastases undergoing SRS treatment shows a significantly higher AUC compared to the detection of Fib and D-D individually(P<0.05).Conclusions:Co-agulation indexes have a certain correlation with the prognosis of patients with NSCLC and BMS treated with SRS.Furthermore Fib and D-D are independent risk factors for the prognosis of these patients and can be used to assess their outcomes.The combined evaluation of the indexes provides a more ideal prognostic assessment.

Objective:To explore the clinical manifestations and characteristics of serum adrenal cortex hormone spectrum in patients with adrenocortical hypercortisolism with different pathological types of adrenal adenoma.Methods:A retrospective analysis was conducted on 68 patients with adrenal Cushing's syndrome who underwent surgical treatment in the Department of Endocrinology and/or Urology, Peking University First Hospital from January 2018 to June 2022. Among them, 12 patients had obvious eosinophilic changes in pathology(eosinophilic group), and 56 patients had no obvious eosinophilic changes(non-eosinophilic group).

In terms of target organ damage, there were 6 cases and 10 cases ( P=0.017) in the eosinophilic group and non eosinophilic group with ventricular wall hypertrophy, 1 case and 0 cases( P=0.030) in the aortic dissection group, and 4 cases and 5 cases ( P=0.024) with four or more types of target organ damage, respectively, with statistically significant differences. Two groups of preoperative serum adrenal cortex hormone profiles were detected by liquid chromatography tandem mass spectrometry. The differences in adrenal cortex hormone profiles and hormone ratios between the two groups were compared. Age, gender, and statistically significant indicators were included in a multivariate logistic regression model to analyze the correlation between each indicator and eosinophilic changes. Results:Adrenal cortical hormone profile of the two groups showed that the serum estrone levels in the eosinophilic group and non-eosinophilic group were 20.27(13.49, 39.81) pg/ml and 12.59(8.08, 21.18) pg/ml ( P=0.034), and 11-hydroxyandrostenedione levels were 692.34(536.19, 1 049.66) pg/ml and 1 157.60(710.78, 1 539.30) pg/ml( P=0.026), with statistically significant differences; There were no statistically significant difference in the expression levels of other hormones ( P>0.05). In terms of hormone ratio, the estradiol/testosterone ratios in the eosinophilic and non eosinophilic groups were 0.14(0.08, 0.62) and 0.04(0.01, 0.09)( P=0.008), the estrone/androstenedione ratios were 0.06(0.05, 0.12) and 0.04(0.03, 0.06)( P=0.007), the 11-hydroxyandrostenedione/androstenedione ratios were 2.26(1.30, 2.69) and 4.03(2.48, 5.25)( P=0.008), the estriol/estrone ratios were 0.10(0.03, 0.29) and 0.25(0.12, 0.51)( P=0.016), the estriol/estradiol were 0.22(0.03, 0.30) and 0.33(0.12, 0.73)( P=0.032), and the differences were statistically significant. The results of multivariate analysis showed that estrone ( OR=1.04, 95% CI 1.01-1.07, P=0.009) and estrone/androstenedione ( OR=25 008 670.29, 95% CI 8.45-74 015 852 572 024.10, P=0.025) were independently associated with eosinophilic pathology. Conclusions:Adrenocortical hypercortisolism patients with eosinophilic pathology have higher levels of serum cortisol secretion, more pronounced inhibition of the hypothalamic pituitary adrenal axis, more significant metabolic disorders and target organ damage, and higher production of estrone.

ObjectiveTo explore the clinical effect of Tiaoxin formula in the treatment of patients with coronary heart disease and anxiety/depression and its impact on serum levels of 5-hydroxytryptamine （5-HT）， β- thromboglobulin （β-TG） and myeloperoxidase （MPO）. MethodA total of 66 patients with coronary heart disease and anxiety/depression were randomly divided into the Tiaoxin formula group and Deanxit group， 33 cases in each group. Both groups were given fundamental western treatment for coronary heart disease. Additionally， the Deanxit group was treated with flupentixol and melitracen tablets and the Tiaoxin formula group was treated with Tiaoxin Formula. The treatment lasted 8 weeks. Before and after treatment， the changes of clinical efficacy， Patient Health Questionnaire （PHQ-9）， Generalized Anxiety Disorder （GAD-7） scale， Seattle Angina Questionnaire （SAQ）， heart rate variability， and serum 5-HT， β-TG and MPO levels， and incidence of adverse reactions in the two groups were observed. ResultThere was no significant difference in the baseline indexes of patients in the two groups， and thus the two groups were comparable. After treatment for 8 weeks， the total effective rate for traditional Chinese medicine （TCM） syndromes in the Tiaoxin Formula group was 87.88% （29/33） higher than 63.64% （21/33） in the Deanxit group （Z=-2.653， P<0.05）. Compared with those before treatment， the PHQ-9 and GAD-7 scores of the two groups were decreased at week 4 and 8 of treatment （P<0.05）， and there was no statistical difference between two groups. And the SAQ dimension scores of the two groups were increased at week 4 and 8 of treatment （P<0.05）. Compared with the Deanxit group， the Tiaoxin Formula group had elevation in two dimension scores： Physical limitation and angina stability （P<0.05）. Compared with the conditions before treatment， the serum 5-HT level in the two groups were increased， while the β-TG and MPO levels were lowered （P<0.05）， and there was no distinct difference between two groups. In addition， the standard deviation of normal-to-normal intervals （SDNN） and standard deviation of average normal-to-normal intervals （SDANN） of the heart rate variability in the Tiaoxin formula group were elevated after treatment （P<0.05）， which were more significant than those of the Deanxit group （P<0.05）. During the treatment period， the incidence of adverse drug reactions in the Tiaoxin formula group was lower than that in the Deanxit group （P<0.05）， and no adverse events were observed in the two groups. ConclusionTiaoxin formula was effective for the treatment of patients with coronary heart disease accompanied by anxiety and depression， which improved the clinical symptoms， increased serum 5-HT levels， and decreased serum β-TG and MPO levels， and had few adverse reactions and high safety for patients， showing a high clinical value.

Objective:To investigate the clinical related factors that affecting peritumoral brain edema (PTBE) and its severity in meningiomas.Methods:A total of 139 patients with meningiomas, admitted to and underwent surgery in our hospital from from January 2017 to October 2020 were chosen; their clinical data were analyzed retrospectively. Meningioma volume and edema volume were calculated from drawn regions of interest on preoperative MRI images by 3D-slicer software. Edema index (EI) was used to evaluate the severity of PTBE. The clinical factors affecting PTBE and EI were determined by statistical methods, and the value of meningioma volume in predicting PTBE was further analyzed.Results:(1) The PTBE incidence was 33.8% (47/139), and average EI was 2.47±0.73. (2) Univariate analysis showed that there was significant difference in percentage of patients with benign/malignant meningiomas, meningioma location, meningioma volume, and Ki-67 index between patients from PTBE group ( n=47) and non-PTBE group ( n=92, P<0.05). Multivariate binary Logistic regression analysis showed that benign/malignant meningiomas and meningioma volumes were independent risk factors for PTBE ( P<0.05). (3) There were significant differences in EI values among patients with different gender, WHO grading, KI-67 index and meningioma volumes ( P<0.05). Multivariate linear regression analysis showed meningioma malignant degrees and meningioma volume were independent risk factors for EI ( P<0.05). (4) Receiver operating characteristic curve showed that the area under curve of meningiomas of the cranial base and non-meningiomas of the cranial base in predicting PTBE was 0.824 and 0.825, respectively, with sensitivity of 0.800 and 0.784, and with specificity of 0.818 and 0.729. Conclusions:(1) Malignant degrees and meningioma volumes are the main factors affecting the incidence of PTBE, and are positively correlated with EI. (2) Meningioma volume has high predictive value in PTBE occurrence.
