Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

Objective To investigate the effect of electroacupuncture at Lianquan point on nerve function deficit in post-stroke dysphagia(PSD)rats and its potential effect on regulating of transi-ent receptor potential vanilic acid subtype 1(TRPV1)signaling pathway.Methods A total of 60 male SD rats with SPF grade were randomly divided into a normal group of 12(only mild inser-tion of the thread,which did not lead to intracerebral artery occlusion),and the remaining 48 rats were established into PSD models.The 36 rats successfully made were randomly divided into mod-el group,treatment group and treatment+caffeic acid group,with 12 rats in each group.The la-tency and frequency of swallowing were recorded.Biological signal collector was applied to detect hypoglossal nerve discharge,lingual muscle threshold intensity,and contraction amplitude.ELISA was employed to detect the content of substance P in serum,toluidine blue staining was conducted to count the number of Nissl bodies in the hypoglossal nucleus,and immunohistochemistry was applied to measure the expression levels of TRPV1,serotonin(5-HT),phosphorylation(p)-p38,and neuronal nitric oxide synthase(nNOS)in the hypoglossal nucleus.Results Compared with the normal group,the model group had shorter swallowing latency,less swallowing frequency,and decreased integrated area of hypoglossal nerve discharge,amplitude of tongue muscle contrac-tion,serum substance P content,threshold strength of tongue muscle,number of Nissl bodies,and the expression levels of TRPV1 and 5-HT,but increased threshold intensity of tongue muscles and expression levels of p-p38 and nNOS in the hypoglossal nucleus(P＜0.05).Compared with the model group,the amplitude of tongue muscle contraction,serum substance P content,number of Nissl bodies,and the expression levels of TRPV1 and 5-HT proteins in rats in the treatment group were increased[2.36±0.26 vs 1.77±0.22,3.46±0.36 vs 2.15±0.18,(3.92±0.38)ng/ml vs(1.69±0.17)ng/ml,(33.60±3.65)vs(24.60±2.34),(19.85±2.11)％vs(9.79±1.07)％,(22.43± 2.34)％vs(10.85±1.13)％,P＜0.05].Conclusion Electroacupuncture at Lianquan point may improve neurological deficits in PSD rats by activating the TRPV1 signaling pathway.

【Objective】 To use Fab segments of autoantibodies to bind to autoantigens on red blood cells in order to block the binding of intact autoantibodies to the autoantigens. 【Methods】 The pure autoantibodies were obtained from the serum of patients by absorption and elution test, then Fab segments were obtained by hydrolyzing IgG autoantibodies at 37℃ overnight with papain enzyme. The Fab segments were used to bind the corresponding autoantigens specifically, thus blocking the binding of intact autoantibodies to autoantigens. 【Results】 The pure autoantibodies obtained through absorption and elution test were all hydrolyzed by papain to generate Fab fragments. When mixed with intact autoantibodies in their respective elution solutions, these Fab fragments were able to block the binding of intact autoantibodies to red blood cell autoantigens. Among the three samples, there was a mutual blocking effect between sample 1 and sample 2, while no mutual blocking effect was observed between sample 2 and sample 3. 【Conclusion】 Fab segment of autoantibody can eliminate the agglutination of intact autoantibodies and erythrocyte autoantigens, and can be applied to clinical practice to solve clinical problems.

Objective:To evaluate the efficacy and safety of oliceridine for treatment of moderate to severe pain after surgery with general anesthesia in patients.Methods:The patients with moderate to severe pain (numeric pain rating scale ≥4) after abdominal surgery with general anesthesia from 14 hospitals between July 6, 2021 and November 9, 2021 were included in this study. The patients were assigned to either experiment group or control group using a random number table method. Experiment group received oliceridine, while control group received morphine, and both groups were treated with a loading dose plus patient-controlled analgesia and supplemental doses for 24 h. The primary efficacy endpoint was the drug response rate within 24 h after giving the loading dose. Secondary efficacy endpoints included early (within 1 h after giving the loading dose) drug response rates and use of rescue medication. Safety endpoints encompassed the development of respiratory depression and other adverse reactions during treatment.Results:After randomization, both the full analysis set and safety analysis set comprised 180 cases, with 92 in experiment group and 88 in control group. The per-protocol set included 170 cases, with 86 in experiment group and 84 in control group. There were no statistically significant differences between the two groups in 24-h drug response rates, rescue analgesia rates, respiratory depression, and incidence of other adverse reactions ( P>0.05). The analysis of full analysis set showed that the experiment group had a higher drug response rate at 5-30 min after giving the loading dose compared to control group ( P<0.05). The per-protocol set analysis indicated that experiment group had a higher drug response rate at 5-15 min after giving the loading dose than control group ( P<0.05). Conclusions:When used for treatment of moderate to severe pain after surgery with general anesthesia in patients, oliceridine provides comparable analgesic efficacy to morphine, with a faster onset.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective:To evaluate the role of histogram analysis based on amide proton transfer weighted (APTw) and apparent diffusion coefficient (ADC) imaging in predicting alpha-thalassemia/mental retardation syndrome X-linked ( ATRX) mutation in isocitrate dehydrogenase ( IDH)-mutant WHO grading 2/3 gliomas. Methods:Seventy-eight patients with IDH-mutant WHO grading 2/3 gliomas, admitted to and confirmed by surgical pathology in Department of Functional Neurosurgery, Neurosurgery Center, Zhujiang Hospital, Southern Medical University from June 2017 to October 2023, including 52 with ATRX wild and 26 with ATRX mutant-type, were selected. Preoperative 3D-APTw and ADC imaging data were collected; after post-processing, the lesions were segmented using lesion outlining method based on inclusion of peri-tumor edema and lesion outlining method based on tumor entity, respectively; after that, the histogram features (the 10 th percentile, 90 th percentile, maximum, mean, median, minimum, skewness, kurtosis, entropy, range, uniformity, and variance) were extracted from 3D-APTw and ADC imaging, respectively. Univariate Logistic regression was used to compare the differences in histogram features between patients in the ATRX mutant group and ATRX wild-type group, and multivariate Logistic regression was used to screen the independent predictors for ATRX mutation (a Logistic regression prediction model was constructed). Predictive values of independent predictors and Logistic regression prediction models in ATRX mutation were evaluated by receiver operating characteristic (ROC) curve. Results:(1) With lesion outlining method based on inclusion of peri-tumor edema, univariate analysis indicated significant difference between ATRX mutant group and ATRX wild-type group in 9 histogram features: relative 3D-APTw minimum, 3D-APTw skewness, relative ADC 90 th percentile, relative ADC mean, relative ADC median, ADC kurtosis, ADC skewness, ADC uniformity, and ADC entropy ( P<0.05). With lesion outlining method based on tumor entity, univariate analysis indicated significant difference between ATRX mutant group and ATRX wild-type group in 9 histogram features: relative 3D-APTw 90 th percentile, 3D-APTw skewness, relative ADC 90 th percentile, relative ADC mean, relative ADC median, ADC kurtosis, ADC skewness, ADC uniformity and ADC entropy ( P<0.05). (2) With lesion outlining method based on inclusion of peri-tumor edema, multivariate Logistic regression showed that 3D-APTw skewness and ADC kurtosis were the independent predictor for ATRX mutation in IDH mutant WHO grading 2/3 glioma patients ( OR=0.168, 95% CI: 0.034-0.800, P=0.025; OR=0.508, 95% CI: 0.319-0.807, P=0.004). The constructed Logistic regression prediction model was P(Y=1|X)=1/1+e -(1.827-1.785×3D-APTw skewness-0.678×ADC kurtosis). With lesion outlining method based on tumor entity, multivariate Logistic regression showed that 3D-APTw skewness and ADC kurtosis were independent predictors for ATRX mutation in IDH mutant WHO grading 2/3 glioma patients ( OR=0.164, 95% CI: 0.034-0.791, P=0.024; OR=0.496, 95% CI: 0.312-0.788, P=0.003); the constructed Logistic regression prediction model was P(Y=1|X)=1/1+e -(1.585-1.810×3D-APTw skewness-0.702×ADC kurtosis). (3) ROC curve analysis showed that, with lesion outlining method based on inclusion of peri-tumor edema, area under ROC curve (AUC) of 3D-APTw skewness and ADC kurtosis was 0.725 (95% CI: 0.608-0.842, P=0.001) and 0.794 (95% CI: 0.685-0.904), respectively ( P<0.001); AUC of Logistic regression prediction model was 0.836 (95% CI: 0.729-0.942, P<0.001), and its sensitivity and specificity were 73.10% and 90.40% when the best threshold was 0.505. ROC curve showed that, with lesion outlining method based on tumor entity, AUC of 3D-APTw skewness and ADC kurtosis was 0.705 (95% CI: 0.587-0.823, P=0.003) and 0.808 (95% CI: 0.704-0.913), respectively ( P<0.001); AUC of Logistic regression prediction model was 0.844 (95% CI: 0.739-0.949, P<0.001), and its sensitivity and specificity were 84.60% and 80.80% when the best threshold was 0.399. Conclusion:Histogram analysis based on 3D-APTw and ADC imaging can predict ATRX mutation in IDH mutant WHO grading 2/3 gliomas to a certain extent.

Objective:To analyze the risk factors of postoperative bleeding after CT-guided percutaneous fly biopsy, and to construct a nomogram model for predicting postoperative bleeding.Methods:A total of 328 patients with CT-guided percutaneous fly biopsy who were admitted to the Affiliated Hospital of Ningbo University School of Medicine from June 2019 to March 2021 were selected, and the general clinical data of the patients were retrospectively analyzed. The patients were divided into observation group and control group according to postoperative bleeding. Statistical analysis was performed on clinical data of patients with statistical significance, receiver operating characteristic (ROC) curve analysis on continuous variables with statistical significance, and Logistic multiple regression analysis on all variables with statistical significance. The risk factors of bleeding complications in CT-guided percutaneous lung biopsy were obtained, and a Nomogram model for predicting bleeding after percutaneous lung biopsy was constructed using the R language software 4.0 "rms" package.Results:The results of the study showed that the size of the mass , the depth of the mass, the number of punctures, the number of cases with inflammation around the lesion , and the number of cases with chronic lung lesions in the observation group were greater than those in the control group: (5.20 ± 1.20) cm vs. (4.30 ± 0.90) cm, (4.30 ± 0.60) cm vs. (2.90 ± 0.30) cm, (2.70 ± 0.60) times vs. (2.30 ± 0.50) times, 38(14, 70) cases vs. 17(24, 60) cases, 102(39, 40) cases vs. 41(59, 40) cases; while the number of normal preoperative prothrombin time (PT) in the observation group was less than that in the control group: 4(5, 80) cases vs. 151(58, 30) cases ( P<0.05). ROC curve analysis was performed on the continuous variables with statistical significance in the control table of patients′general clinical data. The results showed that the area under the curve for swelling size, swelling depth, number of punctures, and number of tissue blocks cut were 0.563, 0.714, 0.680, and 0.559, respectively; the optimal cut-off values were 53.00 cm, 5.56 cm, 2.00 times, and 1.00 blocks ( P<0.05). The univariate indicators were included in the Logistic multiple regression model, and the results showed that tumor depth, puncture times, inflammation around the lesion, and abnormal preoperative PT were the risk factors for complications of percutaneous lung biopsy under CT ( P<0.05). The internal validation results showed that the Nomogram model predicted the risk of bleeding complicated by percutaneous lung biopsy under CT, with a C index of 0.687 (95% CI 0.241 - 1.988). The calibration curve showed good agreement between the observed and predicted values. The Nomogram model predicted percutaneous lung biopsy under CT with a bleeding risk threshold of >0.16, and the Nomogram model provided a clinical net benefit; in addition, the Nomogram model had a higher clinical net benefit than independent indicators. Conclusions:In conclusion, patients with poor coagulation function, inflammation around tumor lesions, deeper lesions, and more puncture times are more prone to bleeding. The Nomogram model constructed in this study has a high clinical application value for predicting the bleeding complications of CT-guided percutaneous lung biopsy.

In addition to the essential pharmacologi-cal effects of opioids,situational cues associated with drug addiction memory are key triggers for drug seeking.CircRNAs,an emerging hotspot regulator in crown genet-ics-play an important role in central nervous system-relat-ed diseases.However,the internal mediating mechanism of circRNA in the field of drug reward and addiction mem-ory remains unknown.Here,we trained mice on a condi-tional place preference(CPP)model and collected nucle-us accumbens(NAc)tissues from day 1(T0)and day 8(T1)for high-throughput RNA sequencing.qRT-PCR revealed that circTmeff-1 was highly expressed in the NAc core but not in the NAc shell,suggesting that it plays a role in addiction memory formation.Meanwhile,the reverse regulation of circTmeff-1 by adeno-associated viruses could both inhibit the formation of addiction mem-ory in the NAc core or shell.Subsequently,the GO and KEGG analyses indicated 21 that circTmeff-1 might regu-late the addiction memory via the MAPK and AMPK path-ways.These findings suggest that circTmeff-1 in NAc plays a crucial role in morphine-dependent memory for-mation.
