Objective To investigate the influence of comorbidities on the prognosis of patients with status epilepticus， to develop Improved Comorbidity Burden Index （ICBI） based on Comorbidity Burden Index （CBI）， and to analyze the practicality of ICBI in assessing nonconvulsive status epilepticus in western China.Methods A total of 396 patients with status epilepticus who were treated in Department of Neurology， Intensive Care Unit， and Emergency Department， West China Hospital， Sichuan University， from December 2016 to December 2022 were enrolled， and all patients met the latest diagnostic criteria for status epilepticus issued by the International League Against Epilepsy （2015 edition）. SPSS 22.0 was used to perform a statistical analysis， and a Logistic regression analysis was used to investigate the influencing factors for in-hospital death and poor prognosis （with a Glasgow Outcome Scale score of 1-3）. CBI score was modified into ICBI score， with the addition of three comorbidities （immune system disorder， thyroid dysfunction， and hypoproteinemia） and consolidation of overlapping items， and the total score was calculated with each comorbidity contributing 1 score. The MedCalc-generated receiver operating characteristic （ROC） curve was used to analyze predictive value， and the area under the ROC curve （AUC） was used to reflect the diagnostic value of ICBI scale.Results Among the 396 patients with status epilepticus included in the study， 43 （10.9%） died in hospital and 114 （28.8%） had a poor prognosis. Digestive system diseases， respiratory system diseases， kidney and urinary system diseases， electrolyte/acid-base imbalance， infection， and immune system disorders were risk factors for in-hospital death of patients with status epilepticus. Digestive system diseases， respiratory system diseases， kidney and urinary system diseases， electrolyte/acid-base imbalance， hypoglycemia/hyperglycemia， infection， coagulation and blood disorders， nervous system disease， cardiovascular diseases， musculoskeletal disorders， and immune system disorders were risk factors for poor prognosis in patients with status epilepticus. The ROC curve analysis showed that ICBI>3 had an AUC of 0.914 in predicting in-hospital death， with a specificity of 71.37% and a sensitivity of 97.67% （P<0.000 1）， and ICBI>3 had an AUC of 0.882 in predicting poor prognosis， with a specificity of 81.56% and a sensitivity of 79.82% （P<0.000 1）. There were 327 patients with convulsive status epilepticus， among whom 41 patients died， and ICBI>3 had an AUC of 0.915 in predicting in-hospital death （P<0.000 1）. There were 100 patients with a poor prognosis， and ICBI>3 had an AUC of 0.867 in predicting poor prognosis （P<0.000 1）.Conclusion The in-hospital mortality rate is 10.9% in patients with status epilepticus in Sichuan， China， and ICBI>3 has a certain value in predicting in-hospital death and poor prognosis in patients with status epilepticus. There is no significant difference in ICBI score between convulsive status epilepticus and nonconvulsive status epilepticus.

OBJECTIVES: To evaluate the effectiveness of single-balloon and double-balloon enteroscopy in diagnosing pediatric small bowel diseases and assess the diagnostic efficacy of computed tomography enterography (CTE) for small bowel diseases using enteroscopy as the reference standard. METHODS: Clinical data from 576 children who underwent enteroscopy at Hunan Children's Hospital between January 2017 and December 2023 were retrospectively collected. The children were categorized based on enteroscopy type into the single-balloon enteroscopy (SBE) group (n=457) and double-balloon enteroscopy (DBE) group (n=119), and the clinical data were compared between the two groups. The sensitivity and specificity of CTE for diagnosing small bowel diseases were evaluated using enteroscopy results as the standard. RESULTS: Among the 576 children, small bowel lesions were detected by enteroscopy in 274 children (47.6%).There was no significant difference in lesion detection rates or complication rates between the SBE and DBE groups (P>0.05), but the DBE group had deeper insertion, longer procedure time, and higher complete small bowel examination rate (P<0.05). The complication rate during enteroscopy was 4.3% (25/576), with 18 cases (3.1%) of mild complications and 7 cases (1.2%) of severe complications, which improved with symptomatic treatment, surgical, or endoscopic intervention. Among the 412 children who underwent CTE, the sensitivity and specificity for diagnosing small bowel diseases were 44.4% and 71.3%, respectively. CONCLUSIONS SBE and DBE have similar diagnostic efficacy for pediatric small bowel diseases, but DBE is preferred for suspected deep small bowel lesions and comprehensive small bowel examination. Enteroscopy in children demonstrates relatively good overall safety. CTE demonstrates relatively low sensitivity but comparatively high specificity for diagnosing small bowel diseases.

Azvudine and nirmatrelvir/ritonavir (Paxlovid) are recommended for COVID-19 treatment in China, but their safety and efficacy in the elderly population are not fully known. In this multicenter, retrospective, cohort study, we identified 5131 elderly hospitalized COVID-19 patients from 32,864 COVID-19 patients admitted to nine hospitals in Henan Province, China, from December 5, 2022, to January 31, 2023. The primary outcome was all-cause death, and the secondary outcome was composite disease progression. Propensity score matching (PSM) was performed to control for confounding factors, including demographics, vaccination status, comorbidities, and laboratory tests. After 2:1 PSM, 1786 elderly patients receiving azvudine and 893 elderly patients receiving Paxlovid were included. Kaplan-Meier and Cox regression analyses revealed that compared with Paxlovid group, azvudine could significantly reduce the risk of all-cause death (log-rank P = 0.002; HR: 0.71, 95% CI: 0.573-0.883, P = 0.002), but there was no difference in composite disease progression (log-rank P = 0.52; HR: 1.05, 95% CI: 0.877-1.260, P = 0.588). Four sensitivity analyses verified the robustness of above results. Subgroup analysis suggested that a greater benefit of azvudine over Paxlovid was observed in elderly patients with primary malignant tumors (P for interaction = 0.005, HR: 0.32, 95% CI: 0.18-0.57) compared to patients without primary malignant tumors. Safety analysis revealed that azvudine treatment had a lower incidence of adverse events and higher lymphocyte levels than Paxlovid treatment. In conclusion, azvudine treatment is not inferior to Paxlovid treatment in terms of all-cause death, composite disease progression and adverse events in elderly hospitalized COVID-19 patients.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

OBJECTIVE: To investigate the association between long-term glycemic control and cerebral infarction risk in patients with diabetes through a large-scale cohort study. METHODS: This prospective, community-based cohort study included 12,054 patients with diabetes. From 2006 to 2012, 38,272 fasting blood glucose (FBG) measurements were obtained from these participants. FBG trajectory patterns were generated using latent mixture modelling. Cox proportional hazards models were applied to assess the subsequent risk of cerebral infarction associated with different FBG trajectory patterns. RESULTS: At baseline, the mean age of the participants was 55.2 years. Four distinct FBG trajectories were identified based on FBG concentrations and their changes over the 6-year follow-up period. After a median follow-up of 6.9 years, 786 cerebral infarction events were recorded. Different trajectory patterns were associated with significantly varied outcome risks (Log-Rank P < 0.001). Compared with the low-stability group, Hazard Ratio ( HR) adjusted for potential confounders were 1.37 for the moderate-increasing group, 1.23 for the elevated-decreasing group, and 2.08 for the elevated-stable group. CONCLUSION Sustained high FBG levels were found to play a critical role in the development of ischemic stroke among patients with diabetes. Controlling FBG levels may reduce the risk of cerebral infarction.

DNA methylation is the first epigenetic modification found in humans.Abnormal changes in DNA methylation are closely associated with the development and progression of diseases.Acupuncture,an important component of traditional Chinese medicine,has been shown to have significant therapeutic efficacy.The mechanisms underlying acupuncture are complex,involving physiological and pathological processes of integrated interactions across multiple targets.However,current research mostly focuses on a single target,highlighting the need for a more upstream approach to the investigation of the mechanisms.Herein,we reviewed studies on the direct or indirect regulation of DNA methylation via acupuncture.We also discussed its mechanisms of action in pain,obesity,depression,and Alzheimer disease,in order to provide a new perspective on the therapeutic mechanisms of acupuncture and the role of DNA methylation in the field of acupuncture research.Future research should concentrate on the effect of acupuncture on the DNA methylation of specific genes,the quantification of changes in DNA methylation at different acupoints,the development of individualized acupuncture prescriptions,further investigation of the specificity of the effects at different acupoint,and the expansion of the research to integrate epigenetics and genomics.This will provide a theoretical basis for the internationalization and the promotion of clinical application of acupuncture.

Objective To investigate the correlation of corneal α angle and κ angle with lens tilt in normal human eyes using a new swept-source optical biometer.Methods A cross-sectional study was conducted,involving 303 healthy eyes(148 right eyes and 155 left eyes)of patients who visited the First Affiliated Hospital of Kunming Medical University from June to August 2024.ZW-30 swept-source optical biometer was used to collect the lens tilt angle,κ angle(distance from the corneal light reflex to the pupil center),and α angle(distance from corneal light reflex to the corneal geometric center,which is the midpoint of the horizontal white to white(WTW)diameter).The degrees(°)and directions of κ angle and α angle were calculated by the ratio of the above measurements to the anterior chamber depth(ACD)respectively.Spearman correlation analysis and linear regression analysis were employed to evaluate the correlations between the magnitude and direction of corneal α angle,κ angle and lens tilt angle.Results The magnitude and direction of corneal α angle,κ angle,and lens tilt angle in the right eye were as follows respectively:(0.54±0.19)mm(7.81°±3.88°),194.43°±39.75°;(0.27±0.23)mm(4.72°±3.90°),181.07°±79.59°;5.52°±1.67°,188.21°±25.73°.For the left eye,the corresponding values were:(0.47±0.27)mm(8.12°±5.26°),336.04°±46.64°;(0.26±0.27)mm(4.45°±4.80°),322.86°±107.79°;5.50°±1.61°,340.65°±32.84°.Spearman's correlation analysis showed that the correlation coefficients between corneal α angle and lens tilt angle in the right eye were 0.609(distance correlation)and 0.625(angle correlation),while those for κ angle were 0.559(distance correlation)and 0.578(angle correlation).In the left eye,the correlation coefficients between corneal α angle and lens tilt angle were 0.545(distance correlation)and 0.552(angle correlation),and those for κ angle were 0.377(distance correlation)and 0.395(angle correlation).In addition,the correlation coefficient between the direction of corneal α angle and the direction of lens tilt angle in the right eye was 0.343,and that for κ angle direction was 0.284;in the left eye,the correlation coefficients were 0.216(α angle direction)and 0.198(κ angle direction),all with statistical significance(P<0.05).Univariate linear regression analysis showed that lens tilt was positively correlated with both corneal α angle and Kappa angle(P<0.05).Conclusions Corneal α angle and κ angle are highly correlated with lens tilt angle in both eyes,and the correlation of corneal α angle is stronger than that of κ angle in both left and right eyes.The correlation expressed by degree(°)is better than that by distance(mm).It is recommended to refer to the corneal α angle and κ angle expressed in degrees during preoperative evaluation.

Objective To explore the expression changes of IGF-1 and IGFBP-3 in childhood obesity and their diagnostic value.Methods Blood samples and corresponding clinical information were collected from patients attending Kunming Children's Hospital from December 2023 and March 2024,and were divided into a control group(healthy children;n=115)and a study group(obese children;n=86).Serum levels of IGF-1 and IGFBP-3 in both groups were measured by using ELISA.Clinical data from both groups were analyzed to assess the correlation between IGF-1 and IGFBP-3 and clinical information,as well as their diagnostic value in childhood obesity.Results Compared to the control group,the study group exhibited a significant increase in weight and BMI(P<0.001)while IGF-1 and IGFBP-3 levels were significantly lower(P<0.05).IGF-1 levels exhibited a negative correlation with total cholesterol,triglycerides,apolipoprotein B,and insulin resistance index(P<0.05),and a positive correlation with apolipoprotein A and fasting insulin(P<0.05);IGFBP-3 displayed the opposite pattern(P<0.05).ROC diagnostic curves indicated that the area under the curve for IGF-1 and IGFBP-3 was 0.598 and 0.665,respectively.Conclusion IGF-1 and IGFBP-3 are expressed at low levels in childhood obesity and are associated with obesity indicators,demonstrating certain diagnostic value.

Recent clinical studies have shown that mutation of phosphatase and tensin homolog deleted on chromosome 10 (PTEN) gene in cancer cells may be associated with immunosuppressive tumor microenvironment (TME) and poor response to immune checkpoint blockade (ICB) therapy. Therefore, efficiently restoring PTEN gene expression in cancer cells is critical to improving the responding rate to ICB therapy. Here, we screened an adeno-associated virus (AAV) capsid for efficient PTEN gene delivery into B16F10 tumor cells. We demonstrated that intratumorally injected AAV6-PTEN successfully restored the tumor cell PTEN gene expression and effectively inhibited tumor progression by inducing tumor cell immunogenic cell death (ICD) and increasing immune cell infiltration. Moreover, we developed an anti-PD-1 loaded phospholipid-based phase separation gel (PPSG), which formed an in situ depot and sustainably release anti-PD-1 drugs within 42 days in vivo. In order to effectively inhibit the recurrence of melanoma, we further applied a triple therapy based on AAV6-PTEN, PPSG^@anti-PD-1 and CpG, and showed that this triple therapy strategy enhanced the synergistic antitumor immune effect and also induced robust immune memory, which completely rejected tumor recurrence. We anticipate that this triple therapy could be used as a new tumor combination therapy with stronger immune activation capacity and tumor inhibition efficacy.
