BackgroundMigraine is a common chronic neurological disease， and patent foramen ovale （PFO） has been closely associated with migraine. Current research primarily focuses on the pathological mechanism and the therapeutic effects of interventional closure， with limited attention paid to the impact of PFO on sleep quality in migraine patients. ObjectiveTo compare the difference in sleep quality between PFO-positive and PFO-negative migraine patients， and to analyzes influencing factors of sleep quality in PFO-positive migraine patients， so as to provide references for clinical interventions to improve sleep quality in PFO-positive migraine patients. MethodsA total of 673 migraine patients who met the diagnostic criteria of migraine in the International Classification of Headache Disorders， third edition （ICHD-3）， and all patients underwent contrast-enhanced transcranial Doppler （c-TCD） and transthoracic echocardiographic right heart contrast echocardiography （cTTE） in the Third Hospital of Mianyang from January 2020 to October 2024. Basic demographic data were collected using a self-designed questionnaire， headache severity was assessed with the Visual Analogue Scale （VAS）， and sleep quality was invaluated using the Pittsburgh Sleep Quality Index （PSQI）. PFO patients was diagnosed through c-TCD combined with c-TTE. Binary logistic regression analysis was employed to examine the influencing factors of sleep quality in PFO-positive migraine patients. ResultsA total of 673 （100.00%） migraine patients were enrolled， including 223 PFO-positive cases （33.14%） and 450 PFO-negative cases（66.86%）. The PFO-positive group showed significantly more severe headache severity （χ²=15.799， P<0.01） and poorer sleep quality （χ²=14.377， P<0.01） compared with PFO-negative group. PFO-positive patients demonstrated significantly higher barrier factor scores of sleep quality， sleep latency， sleep efficiency， sleep disturbance， hypnotic medication use， and daytime dysfunction compared with PFO-negative counterparts （t=3.634， 3.269， 2.785， 3.428， 2.907， 3.637， Bonferroni adjust P<0.05/7=0.007）.By contrast， no significant difference was noted in sleep duration scores between the two groups（t=2.349， Bonferroni adjust P>0.05/7=0.007）.The Binary Logistic regression analysis revealed that age （OR=1.021， 95% CI： 1.001~1.041）， headache severity （OR=6.030， 95% CI： 4.085~8.901）， and PFO grade （OR=1.893，95% CI： 1.288~2.784）were significant influencing factors for sleep quality in migraine patients with PFO. ConclusionMigraine patients with PFO-positive exhibited poorer sleep quality compared wtih PFO-negative patients. Older age， higher headache servity， and more severe PFO grade are identified as risk factors for impaired sleep quality in PFO-positive migraine patients.

Objective To evaluate the clinical use of the baseline CT angiography(CTA)quantitative score(self-designed collateral circulation quantitative,SD-CCQ)in determining the collateral circulation compensation status in patients with acute ischemic stroke(AIS),as well as the reliability and accuracy of the SD-CCQ score and the Alberta Stroke Program Early CT Score(ASPECTS).Methods Retrospective analysis was made on the clinical and imaging data,including CT,CTA and DWI image data,of 84 patients who were admitted for acute ischemic stroke to the Department of Neurorehabilitation of Zhongshan Hospital of Traditional Chinese Medicine from January 2020 to December 2022.Their CTA source images were annotated using a multi-task deep learning method for vascular segmentation.The ASPECTS score and SD-CCQ score were then applied to the CTA images following vascular segmentation in order to assess the collateral circulation compensation of AIS patients.The Kappa test was used to assess the consistency of the two methods used to assess collateral circulation,and the multifactorial Logistic regression analysis was used to examine the relationship between the SD-CCQ and the prognosis of the AIS patients.Results ASPECTS score had good consistency with SD-CCQ score in evaluating collateral circulation in AIS patients(κ=0.65,P＜0.001),and the diagnostic accuracy of the latter for benign collateral circulation in AIS was 96.15％.Logistic regression analysis showed that the new collateral circulation score,baseline NIHSS,and DWI infarct volume were the main factors affecting the long-term prognosis of AIS patients.Conclusion The new scoring system SD-CCQ can be used to evaluate the compensatory status of collateral circulation in AIS patients,which may help in clinical treatment decision-making and prognosis prediction.

ObjectiveTo establish a rat model of hyperuricemia （HUA）， to study the effect of Liqing granules on lowering serum uric acid， and to evaluate its safety . MethodsMale SD rats were randomly divided into solvent control group and model group according to their body weight. For the model group， serum uric acid （SUA） was determined after 7 days of intra-gastric administration of potassium oxyazinate. The model group were randomly divided into model control group， positive control group， and low， medium， high dose group based on SUA level. Each group from the model group continued to receive potassium oxyazinate in the morning. The animals in the model groups received 0.5% CMC-Na， 10 mg·kg^-1 benzbromarone （Doses by body weight） and Liqing granules 0.6， 1.2， 2.4 g·kg^-1 （Doses by body weight）， respectively in the afternoon. 0.5% CMC-Na suspension with the same volume was given both in the morning and afternoon for the solvent control group. Levels of SUA， creatinine （CREA）， alanine aminotransferase （ALT） and aspartate transaminase （AST） were determined after 32 and 45 days administration of the test substance. ResultsSUA of the model group was （218±23） μmol·L^-1 after 7 days of modeling， which was significantly higher than that of the solvent control group （P<0.001）. After 32 days administration of the test substance， SUA didn’t significantly decrease in each dose group （P>0.05）. CREA in the medium and high dose groups significantly decreased （P<0.05）. After 45 days administration of the test substance， SUA in each dose group was significantly decreased （P<0.001）， but CREA， ALT， and AST were not significantly different in each dose group in comparison with the model control group （P>0.05）. ConclusionLiqing granules can assist in lowering blood serum uric acid in the rat HUA model， and no damage to liver and kidney function is found.

Objective:To analyze protein profiles in septic patients, and to find potential new targets for the diagnosis and treatment of sepsis.Methods:A cross sectional observational study was conducted. From January to December 2019, 12 septic patients and 9 healthy volunteers were recruited in the emergency intensive care unit (EICU) of the emergency department of the Affiliated Hospital of Southwest Medical University. The peripheral blood of the two groups was collected for protein mass spectrometry analysis, and the data-independent acquisition technology was used to obtain the expression data of each protein. The obtained data was imported into the online network tool Integrated Differential Expression and Pathway analysis (IDEP2), the data underwent ID converted and were homogenized to verify their comparability, and then principal component analysis was used to eliminate outlier data. Then data with P < 0.05, log 2fold change (FC) > 1 or log 2FC < -1 were considered to have a statistically significant difference, and the differential proteins were screened out. On the DAVID website, the screened differential proteins would be analyzed by gene ontology (GO), and the biological process, cellular components, and molecular function of the proteins would be analyzed. Protein enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed. Protein-protein interaction (PPI) analysis was performed through the Search Tool for the Retrieval of Interacting Genes Database (STRING) website to find closely related proteins. Results:The data in this study were shown to be comparable after normalization. A total of 125 differential proteins were screened, of which 99 were up-regulated and 26 were down-regulated. GO enrichment analysis discovered that these proteins were mainly extracellular, with cellular regulatory functions and catalytic functions involved in biological regulation, metabolic process and immune process. KEGG pathway analysis suggested that these proteins were involved in amino acid, carbohydrate metabolism and immune-related pathways. PPI analysis showed that key proteins included matrix metalloproteinase 14 (MMP14), fibulin 1 (FBLN1), plasma kallikrein 1 (KLKB1), etc., and finally screened out MMP14 and KLKB1, which were closely related to inflammation and immunity. Both might be potential new targets for early diagnosis and treatment of sepsis.Conclusion:MMP14 and KLKB1 may be potential biomarkers for the diagnosis, treatment and prognosis of sepsis.

Objective:To present the clinical characteristics and treatment on patients with ectopic adrenocorticotropic hormone(ACTH) syndrome (EAS) caused by the retroperitoneal paraganglioma.Methods:The clinical data of a case of EAS caused by retroperitoneal paraganglioma were analyzed retrospectively, and the related literature at home and abroad was reviewed.Results:The 53-year-old female patient was admitted to endocrinology department due to a fifteen-year history of hypertension, accompanied by fatigue for three months, headache and dizziness for one month. The laboratory data demonstrated severe hypokalemia, high level of serum and urinary cortisol, while the ACTH level remained unsuppressed. The 24 h urinary vanillyl mandelic acid (VMA) and serum free methoxyepinephrine (MNs) level were elevated. The abdominal computed tomographic scan suggested a retroperitoneal mass next to the abdominal aorta. After the retroperitoneal tumor resection was performed, immunohistochemical staining of the tumor revealed Syn (+ ), CgA (+ ), ACTH (focal + ). By the retrospective analysis of 22 similar cases from 16 papers and the case summarized above, we found that most patients with EAS caused by the paraganglioma could demonstrate the typical clinical features of Cushing′s syndrome, while lack of the manifestation of paraganglioma. Therefore, preoperative preparations for paraganglioma were usually neglected.Conclusions:Ectopic ACTH syndrome (EAS) originating from paraganglioma is very rare. To improve the diagnosis rate, examination for catecholamine, MNs and 24 h urinary VMA before surgery in patients with EAS is suggested. Considering surgical resection as the optimal treatment, comprehensive preoperative preparations for both paraganglioma and Cushing′s syndrome are significant. A genetic test for pheochromocytoma/ paraganglioma and lifelong postoperative follow-up are also recommend.

Objective:To evaluate the mid- and long-term outcomes of Dynesys hybrid surgery (in some segments act as a non-fusion device, in other segments act as an alternative of rigid fixation in combination with interbody fusion) in the treatment of multi-segmental lumbar degenerative disease (LDD).Methods:The data of 27 patients who received Dynesys hybrid surgery (hybrid group) for the treatment of LDD from May 2011 to September 2016 and completed the follow-up were retrospectively analyzed. Among them, there were 8 males and 19 females; their average age was 59.1±11.9 years (23-78 years). Main diagnosis: 13 cases of lumbar spinal stenosis, 14 cases of lumbar disc herniation; 4 cases of combined lumbar dynamic position instability, 7 cases of combined lumbar spondylolisthesis. There were 15 cases of two-segment disease, 11 cases of three-segment disease, and 1 case of four-segment disease. Segments distribution: 9 cases of L 3-L 5, 6 cases of L 4-S 1, 7 cases of L 3-S 1, 4 cases of L 2-L 5, and 1 case of L 2-S 1. Midline incision was used to exposure, followed by bilateral pedicle screws implantation, and interbody fusion cage with bone grafting were performed at the fusion level. Twenty-seven patients who underwent TLIF+rigid internal fixation during the same period were included as the control group. Clinical outcomes were measured by visual analog scale (VAS) for low back pain and leg pain, and Oswestry disability index (ODI). Radiological outcomes included fusion rate, intervertebral disc height (DH) of surgical segments and the proximal adjacent segment, range of motion (ROM) of non-fusion segments and the proximal adjacent segment. At the same time, the occurrence of complications was observed. Results:Patients of Hybrid group and control group were followed up for an average of 83.8±20.9 months (48-112 months) and 87.3±16.2 months (53-114 months), respectively. Baseline data of the two groups (average follow-up time, age, gender, surgical level, diagnosis) showed no significant difference. The operation time (183.0±27.8 min) and intraoperative blood loss (301.9±178.9 ml) in the hybrid group were significantly lower than those in the control group (operation time t=2.337, P=0.023; blood loss t=2.706, P=0.01). At the final follow-up, the VAS scores of low back pain and leg pain (low back pain t=12.164, P<0.001; leg pain t=20.603, P<0.001), as well as ODI were significantly improved ( t=22.827, P<0.001). A total of 32 segments received TLIF+Dynesys stabilization and 35 segments received Dynesys non-fusion stabilization in the hybrid group, with 28 segments (87.5%) achieved solid fusion at 1-year follow-up. There were 67 fusion segments in the control group, and the fusion rate at 1-year follow-up was 85.1%. DH of non-fusion segments were lower than that before surgery with statistical significance at final follow-up ( t=2.647, P=0.012), while DH of the fusion segments in the hybrid group and the surgical segments in the control group increased compared with that before surgery at the final follow-up. A certain degree of ROM (2.4°±1.5°) was retained of the non-fusion segments at the final follow-up; the ROM of proximal adjacent segments of non-fused segments was significantly smaller than that of proximal adjacent segments of fused segments ( t=2.126, P=0.044). In the hybrid group, screw loosening occurred in 4 patients (8 screws) and adjacent segment degeneration (ASD) occurred in 5 patients. In the control group, screw loosening occurred in 3 patients (6 screws), while ASD occurred in 8 patients. No screw fracture was observed during the follow-up period and no patients received reoperation. Conclusion:Hybrid surgery of Dynesys stabilization combined with interbody fusion is a safe and effective method for the treatment of multi-segmental LDD. Compared with multi-segmental fusion, this lumbar hybrid surgery has the advantages of less trauma and retaining partial segmental ROM.

To investigate the expression and significance of H3K27M and Ki-67 in pediatric glioma. Methods: Immunohistochemistry was used to detect the expression of H3K27M and Ki-67 in 38 patients with pediatric glioma and 10 patients with normal brain tissue, who enrolled in Yuquan Hospital, Tsinghua University from November 2013 to June 2018. The results were analyzed using appropriate statistical methods. Results: The positive expression of H3K27M was not significantly correlated with gender, age, and tumor site (P>0.05). However, it was significantly correlated with the tumor pathological grade (P<0.05). The positive expression rate of Ki-67 in pediatric glioma was 100%. The high label index of Ki-67 was not significantly correlated with gender and age (P>0.05). However, it was significantly correlated with the pathological grade and tumor site (P<0.05). There were no significant correlations between the ptients' gender, age, and survival time (P>0.05). There were significant correlations between the tumor pathological grade, tumor location, H3K27M protein-positive, Ki-67 high label index, and patient survival time (P<0.05). Conclusions: The expression level of H3K27M and Ki-67 appeared to be related to the pathological grade and prognosis of pediatric glioma. Besides, the expression of H3K27M and Ki-67 protein in glioma tissue were correlated. This could be useful for studying the occurrence and development of glioma as well as investigating potential targeted therapy options.

OBJECTIVE: To investigate the correlation between the severity of obstructive sleep apnea syndrome (OSAS) and red cell distribution width (RDW) in elderly patients. METHODS: A cross-sectional study was conducted among 311 elderly patients diagnosed with OSAS in the snoring clinic between January, 2015 and October, 2016 and 120 healthy controls without OSAS from physical examination populations in the General Hospital of PLA. The subjects were divided into control group with apnea-hypopnea index (AHI) <5 (=120), mild OSAS group (AHI of 5.0-14.9; =90), moderate OSAS group (AHI of 15.0-29.9; =113) and severe OSAS group (AHI ≥ 30; =108). The clinical characteristics and the results of polysomnography, routine blood tests and biochemical tests of the subjects were collected. Multiple linear regression analysis was used to examine the correlation between OSAS severity and RDW. RESULTS: The levels of RDW and triglyceride were significantly higher in severe OSAS group than in the other groups ( < 0.01). The levels of fasting blood glucose and body mass index were significantly higher in severe and moderate OSAS groups than in mild OSAS group and control group ( < 0.05 or < 0.01). Multiple linear regression analysis showed that AHI was positively correlated with body mass index (β=0.111, =0.032) and RDW (β=0.106, =0.029). The area under ROC curve of RDW for predicting the severity of OSAS was 0.687 (=0.0001). CONCLUSIONS The RDW increases as OSAS worsens and may serve as a potential marker for evaluating the severity of OSAS.
