BACKGROUND: Inflammation plays a critical role in severe cerebral venous thrombosis (CVT) pathogenesis, but the benefits of anti-inflammatory therapies remain unclear. This study aimed to investigate the association between steroid therapy combined with anticoagulation and the prognosis of acute/subacute severe CVT patients. METHODS: A prospective cohort study enrolled patients with acute/subacute severe CVT at Xuanwu Hospital (July 2020-January 2024). Patients were allocated into steroid and non-steroid groups based on the treatment they received. Functional outcomes (modified Rankin scale [mRS]) were evaluated at admission, discharge, and 6 months after discharge. Serum high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), cerebrospinal fluid (CSF) IL-6, and intracranial pressure were measured at admission and discharge in the steroid group. Fundoscopic Frisén grades were assessed at admission and 6 months after discharge. Univariate and multivariate logistic regression were used to evaluat associations between steroid use and favorable outcomes (mRS ≤2) at the 6-month follow-up. Paired tests assessed changes in hs-CRP and other variables before and after treatment, and Spearman's correlations were used to analyze relationships between these changes and functional improvements. RESULTS: A total of 107 and 58 patients in the steroid and non-steroid groups, respectively, were included in the analysis. Compared with the non-steroid group, the steroid group had a higher likelihood of achieving an mRS score of 0-2 (93.5% vs . 82.5%, odds ratio [OR] = 2.98, P  = 0.037) at the 6-month follow-up. After adjusting for confounding factors, the result remained consistent. Pulsed steroid therapy did not increase mortality during hospitalization or follow-up, nor did it lead to severe steroid-related complications (all P  >0.05). Patients in the steroid group showed a significant reduction in serum hs-CRP, IL-6, CSF IL-6, and intracranial pressure at discharge compared to at admission, as well as a significant reduction in the fundoscopic Frisén grade at the 6-month follow-up compare to at admission (all P  <0.001). A reduction in serum inflammatory marker levels during hospitalization positively correlated with improvements in functional outcomes ( P  <0.05). CONCLUSION: Short-term steroid use may be an effective and safe adjuvant therapy for acute/subacute severe CVT when used alongside standard anticoagulant treatments, which are likely due to suppression of the inflammatory response. However, these findings require further validation in randomized controlled trials. TRAIL REGISTRATION ClinicalTrials.gov , NCT05990894.

Objective To explore the diagnostic value of alkaline phosphatase on the surface membrane of neutrophils(mNAP)in bloodstream infections(BSI)of Gram-negative bacteria(GNB)and Gram-positive bacteria(GPB).Methods A total of 418 patients diagnosed with BSI at Donghai People's Hospital from January 2022 to December 2023 were enrolled in the study.Based on the results of Gram staining from positive blood cultures,the patients were divided into GNB bacteremia(n=329)and GPB bacteremia(n=89).Additionally,35 hospitalized patients with systemic inflammatory response syndrome(SIRS)during the same period were selected as the control group.Their clinical data,routine laboratory test results,blood cultures and venous blood samples were collected,and the expression levels of mNAP were detected by flow cytometry.The receiver operating characteristics(ROC)curve was used to evaluate the diagnostic performance of mNAP for BSI of GNB and GPB.Results The expression levels of mNAP in the GPB infection,GNB infection and SIRS groups were 9 588(5 677,11 343)AB/C,16 616(11 853,22 035)AB/C,and 5 738(2 613,9 178)AB/C,respectively,and the difference among them was statistically significant(H=43.95,P＜0.000 1).Further pairwise comparisons showed that the expression levels of mNAP in the GNB infection group were significantly higher than those in the GPB infection group(U=203.0,P＜0.000 1)and the SIRS group(U=445.0,P＜0.000 1).Meanwhile,the expression levels of mNAP in the GPB infection group were significantly higher than that in the SIRS group(U=583.0,P＜0.000 1).The area under the ROC curve(AUCROC)of mNAP for predicting the BSI of GNB was 0.91(95%CI:0.85-0.96).When the cut-off value was 10 820 AB/C,its sensitivity and spe-cificity were 80.00%and 88.57%,respectively.The AUCROC of mNAP for predicting the BSI of GPB was 0.69(95%CI:0.55-0.83).When the cut-off value was 10 859 AB/C,its sensitivity and specificity were 33.00%and 88.13%,respectively.Conclusion The di-agnostic efficiency of mNAP for the BSI of GNB is significantly higher than that for the BSI of GPB,which may become a novel biologi-cal marker for distinguishing the BSI of GNB and GPB.

Objective To observe the effect of buccal needle therapy on perioperative analgesia in patients undergoing laparoscopic radical colon cancer surgery.Methods Sixty patients underwent dective laparoscopic radical of colon cancer surgery were selected,32 males and 28 females,aged 45-74 years,BMI 18.5-25.0 kg/m2 and ASA physical status Ⅱ or Ⅲ.The patients were divided into two groups using the randomized numerical table method:buccal needle group and control group,30 patients in each group.Before the induction of anesthesia,the buccal needle group was given buccal needle therapy once,and buc-cal needle therapy was performed once a day at 9 a.m.in the postoperative period,leaving the needle in place for 30 minutes each time,for 3 consecutive days of treatment,and the control group was not treated with buccal needle therapy.The amount of intraoperative propofol,remifentanil,sufentanil used in the 48 hours postoperative period and recorded.VAS pain scores were recorded at 1 hour,4,24,and 48 hours postoperatively.Venous blood was collected at the time of admission to the hand room and at 1 day,2,and 3 days postoperatively,respectively,and the concentrations of plasma C-reactive protein(CRP),interleu-kin-6(IL-6),and tumor necrosis factor-alpha(TNF-α)were measured.The occurrence of adverse reactions within 48 hours after operation was recorded.Results Compared with the control group,intraop-erative propofol,remifentanil,the amount of sufentanil used and the number of analgesic pump presses with-in 48 hours after operation in the buccal needle group were significantly reduced in the buccal needle group(P＜0.05),VAS pain scores were significantly lower at 1 hour,4,24,and 48 hours postoperatively(P＜0.05),CRP,IL-6,and TNF-α concentrations were significantly lower at 1 day,2,and 3 days postopera-tively(P＜0.05),and nausea and vomiting,incidence of laryngospasm and laryngeal discomfort were sig-nificantly reduced(P＜0.05).Conclusion The perioperative use of buccal needle therapy in patients un-dergoing laparoscopic radical colon cancer surgery can effectively reduce pain,inhibit inflammatory respon-ses,and decrease the incidence of postoperative adverse reactions.

In the theoretical teaching of valvular heart disease, the traditional teaching method makes the learners feel very abstract and the learning effect is poor. In bedside teaching, the heart characteristics of specific patients cannot be directly displayed to learners, and learners are difficult to construct theoretical knowledge and clinical performance. Based on the clinical bedside internship based on experiential learning theory, this study uses cardiac virtual image technology to reconstruct the cardiac images of clinical patients, restoring the internal structure of their hearts, supplemented by dynamic blood flow images, to make learners can clarify the relationship between cardiac morphology and hemodynamics, so that learners can intuitively learn these knowledge. Through the teaching practice of this study, it is found that high-quality curriculum design and guided teaching combined with the application of new VR technology can significantly improve the learning experience and effect of learners.

Objective:To explore the incidence and severity of esophageal clearance impairment in stroke survivors with dysphagia, the clinical characteristics of patients with abnormal esophageal clearance, and their relationship with swallowing physiology, penetration and aspiration.Methods:Clinical data were collected describing 174 stroke survivors whose swallowing had been studied videofluoroscopically. In each selected case there was a good anterior-posterior view of esophageal clearance. Their anterior-posterior and lateral imaging results while swallowing 5ml of high-consistency food were analyzed. The esophageal clearance item of the modified barium swallow impairment profile was then used to rate each subject′s esophageal clearance and each physiological component of swallowing in the oral and pharyngeal phases. The Rosenbek penetration aspiration scale was employed evaluate the safety of their swallowing.Results:Seventy of the patients (40.2%) displayed abnormal esophageal clearance, and more than half of the 70 (43 patients, 24.7%) showed mid- to distal esophageal retention. Those with abnormal esophageal clearance had a higher average age and more severe overall impairment in the pharyngeal phase of swallowing. Esophageal clearance was not, however, significantly correlated with swallowing physiology in the oral phase or with penetration or aspiration grade. There were, however, significant positive correlations with laryngeal elevation, anterior hyoid excursion, pharyngeal stripping waves, pharynx contraction, upper esophageal sphincter opening, tongue base retraction and pharyx residue.Conclusion:Stroke survivors with dysphagia may display abnormal esophageal clearance. The risk is closely related to age and the severity of the dysphagia. Abnormal physiology during the pharyngeal phase of swallowing and reduced pharyngeal stripping may predict abnormal esophageal clearance. Swallowing assessment can be made more comprehensiveness and systematic by incorporating anterior-posterior videography in routine barium swallowing studies.

Serine/arginine-rich splicing factor 7 (SRSF7), a known splicing factor, has been revealed to play oncogenic roles in multiple cancers. However, the mechanisms underlying its oncogenic roles have not been well addressed. Here, based on N⁶-methyladenosine (m⁶A) co-methylation network analysis across diverse cell lines, we find that the gene expression of SRSF7 is positively correlated with glioblastoma (GBM) cell-specific m⁶A methylation. We then indicate that SRSF7 is a novel m⁶A regulator, which specifically facilitates the m⁶A methylation near its binding sites on the mRNAs involved in cell proliferation and migration, through recruiting the methyltransferase complex. Moreover, SRSF7 promotes the proliferation and migration of GBM cells largely dependent on the presence of the m⁶A methyltransferase. The two m⁶A sites on the mRNA for PDZ-binding kinase (PBK) are regulated by SRSF7 and partially mediate the effects of SRSF7 in GBM cells through recognition by insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2). Together, our discovery reveals a novel role of SRSF7 in regulating m⁶A and validates the presence and functional importance of temporal- and spatial-specific regulation of m⁶A mediated by RNA-binding proteins (RBPs).

Objective:To study the safety and efficacy of hiatal hernia-endoscopic submucosal dissection (HH-ESD) for the treatment of giant hiatal hernia (>3 cm in length) complicated with refractory gastroesophageal reflux disease (GERD).Methods:Patients with giant hiatal hernia complicated with refractory GERD who voluntarily received HH-ESD at the Digestive Endoscopy Center of the Affiliated People's Hospital of Inner Mongolia Medical University from April 2018 to March 2020 were included in the clinical study. The completion of HH-ESD and the occurrence of complications were observed, and the changes of indicators before and after the treatment were observed, including gastroesophageal reflux disease-health related quality of life (GERD-HRQL) score, gastroesophageal reflux disease questionnaire (GERD-Q) score, endoscopy results, 24 h esophageal pH monitoring results, esophageal high-resolution manometry results and proton pump inhibitor (PPI) usage.Results:Data of 10 patients were collected during the study, with a medical history of 2-10 years. All patients successfully underwent HH-ESD treatment. No adverse events such as perforation and massive bleeding occurred during the operation, and the hospital stay was 6-12 days. Dysphagia occurred in 3 cases after the operation, which was relieved spontaneously within 3 or 6 months. The preoperative GERD-HRQL scores ranged from 19 to 29, which were reduced to 0-14 and 0-8 at 3 and 12 months after the operation, respectively. The preoperative GERD-Q score was 9-17, and the scores at 3 and 12 months after the operation were all 6-9, which were significantly lower than those before. Gastroscopy showed that esophagitis was improved in all patients, hernia sac was reduced, and Hill grade was reduced compared with that before. The preoperative DeMeester score was 30.3-247.1, and the postoperative 12-month score was 0.2-29.9, which was significantly lower than that before. The long diameter of hiatal hernia was 3.0-6.0 cm before the operation and 0-5.0 cm at 12 months after, which was smaller than that before. At 12 months of the follow-up, 7 patients had stopped PPI, and the remaining 3 had changed to intermittent oral PPI.Conclusion:Preliminary results show that HH-ESD is safe and effective for the treatment of giant hiatal hernia complicated with refractory GERD.

Objective:To investigate the effect of enhanced external counterpulsation(EECP)on heart failure with preserved ejection fraction(HFpEF)and hemodynamics in elderly patients.Methods:Clinical data of 66 elderly HFpEF patients admitted to the enhanced external counterpulsation center of our hospital from January 2018 to December 2019 were retrospectively analyzed.The primary assessment parameter was the six-minute walk distance, and the secondary parameters included the Minnesota Living with Heart Failure Questionnaire(MLHFQ). Noninvasive hemodynamic parameters including the cardiac index(CI), stroke volume(SV), isovolumic relaxation period(A2-mitral valve opening, A2-O), pulmonary capillary wedge pressure(PCWP)and total peripheral resistance(TPR)were monitored and mean arterial blood pressure(MAP)was calculated.Results:After EECP treatment, the six-minute walk distance increased(372±87 m vs.341±85 m, P<0.05), the score of MLHFQ decreased(47.0±16.0 vs.50.0±17.0, P<0.05), CI increased(2.8±0.7)L·min -1·m -2vs.(2.6±0.6)L·min -1·m -2( P<0.05), SV, PCWP and A2-O did not show significant change(73.3±16.4 ml vs.71.5±17.1 ml, 10.0±3.3 mmHg vs.11.0±3.6 mmHg, 1 mmHg=0.133 kPa, 98.0±29.5 ms vs.91.0±29.1 ms, P>0.05), TPR decreased(1 719.0±427.0 DS/cm 5vs.1 821.0±508.0 DS/cm 5, P<0.05), and there was no significant change in MAP(96.9±10.7 mmHg vs.98.8±13.1 mmHg, P>0.05), compared with pre-EECP treatment levels.Compared with patients without hypertension, MAP decreased in patients with hypertension(14 cases), when stratified by the initial MAP( P<0.05). Conclusions:For elderly patients with HFpEF, EECP can increase the six-minute walk distance, improve the quality of life and hemodynamic parameters, and is a safe adjuvant treatment.

Objective:To explore clinical application value of immediate breast reconstruction with silicone prosthesis after nipple areolar sparing mastectomy for breast cancer.Methods:The clinical data of 30 breast cancer patients underwent immediate breast reconstruction with the silicone prosthesis after nipple areolar sparing mastectomy from January 2016 to January 2018 were collected. In the observation group, 15 patients underwent immediate breast reconstruction with the silicone prosthesis after nipple areolar sparing mastectomy. In the control group, 15 patients underwent conventional modified radical mastectomy only. The differences of operation indicator and postoperative complications between the two groups were compared, and the postoperative cosmetic effects were evaluated.Results:The patients successfully completed prosthetic breast reconstruction in the observation group. The surgical time and indwelling time of the drainage tube in the observation group were both increased compared with the control group, and the difference was statistically significant ( t=118.8 and t=23.9, P<0.05). There were no statistically significant differences between the two groups in the complications of postoperative flap necrosis, subcutaneous hematoma, intraoperative infection and incision dehiscence ( P>0.05). The total complications rate of the observation group was 40%, compared with the control group (20%), there were not statistically significant differences ( P>0.05). The postoperative aesthetic effect evaluation showed that the reconstructed breast was full in shape and basically symmetrical to the contralateral side, with an excellent and good rate of 83.3%. The patients were satisfied with the appearance of the breast. All patients were followed up for 12 to 36 months with the average time of 24 months, and local recurrence and distant metastasis were not observed. Conclusions:In the modified radical mastectomy for breast cancer with preserved nipple and areola, the immediate application of silicone prosthesis for breast reconstruction has the advantages of less trauma, faster postoperative recovery and better cosmetic effect, which is worthy of clinical application.

Objective:This study compares the magnetic resonance imaging (MRI) appearance of two types of breast tissue markers to investigate the appropriate clinical application of the markers.Methods:Breast MRI of 69 patients (78 masses) with breast tissue markers had been placed were analyzed retrospectively from November 2015 to August 2018 in our hospital. The sizes and shapes of breast tissue markers were assessed in axial fat-suppressed T2-weighted images, T1-weighted images and contrast-enhanced T1-weighed images.Results:The length of the coil nickel-free stainless steel markers were greater than ribbon titanium markers, with statistical difference in fat-suppressed T2-weighted images ( P=0.039). In contrast-enhanced T1-weighted images, all coil nickel-free stainless steel markers showed >6 mm diameter and round shape, and ribbon titanium markers showed >6 mm diameter ( n=20) or ≤6 mm diameter ( n=8), and round ( n=20), dot ( n=7) or band ( n=1) shapes. The categories of sizes and shapes in two types of breast tissue markers both had statistical significance ( P<0.001, P<0.001). Conclusions:Small breast lesions with breast tissue markers are not suitable for MRI evaluation. The artifact of ribbon titanium markers is smaller than coil nickel-free stainless steel markers, so they have less impact for lesions. The choice of the breast tissue markers and image evaluation methods should depend on the different clinical conditions.
