ObjectiveTo explore the role of the histone deacetylase Sirtuin-1 （SIRT1）/p53 signaling pathway in promoting apoptosis of non-small cell lung cancer cells （NSCLC） induced by the co-stimulatory molecule B7 homolog 3 （B7-H3）. MethodsThe GEPIA 2 platform was used for survival analysis of NSCLC patients based on B7⁃H3 gene expression levels. The Gene Enrichment Analysis （GSEA） method was used to analyze the enrichment characteristics of B7⁃H3 molecules in the gene set of cell apoptosis. In the non-small cell lung cancer A549 cell line， B7⁃H3 was knocked down， and the protein expression levels of SIRT1 and p53 were detected by Western blot. B7⁃H3 was overexpressed in A549 cells and the apoptosis rate was analyzed by flow cytometry after Annexin V/PI double staining. Overexpression of B7⁃H3 and knockdown of SIRT1 were performed in A549 cell line. The expression levels of p53 and apoptosis-related proteins B-cell lymphoma/leukemia-2 （Bcl-2） and Bcl-2-associated X protein （Bax） were detected respectively by Western blot. Cell apoptosis rate was analyzed by flow cytometry after Annexin V/PI double staining. ResultsThe overall survival of the B7-H3 high-expression group was significantly lower than that of the low-expression group （P<0.01）. B7-H3 was significantly enriched in the cell apoptosis signaling pathway and the p53 signaling pathway （P<0.05）. Compared with the control group， the expression of SIRT1 was significantly downregulated， and p53 was significantly upregulated in the B7⁃H3 knockdown group （both P<0.001）. Overexpression of B7-H3 significantly up-regulated SIRT1 protein expression （P<0.05）， down-regulated p53 expression （P<0.01）， and markedly increased the Bcl-2/Bax ratio of apoptosis-related proteins （P<0.001）. The results of Annexin V/PI double staining showed that the apoptosis rate of A549 cells with overexpressed B7⁃H3 decreased （the apoptosis rate of the control group was 26.72%±4.13%， while that of the B7⁃H3 overexpression group was 13.87%±0.82%； P<0.01）. In B7-H3-overexpressing cell lines， SIRT1 knockdown significantly reversed apoptosis （P<0.05）， up-regulated p53 protein expression （P<0.001）， and markedly reduced the Bcl-2/Bax ratio （P<0.001）. ConclusionB7-H3 molecule inhibits the apoptosis of non-small cell lung cancer cells via the SIRT1/p53 signaling pathway.

OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors （DTIs） in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital （the Affiliated Hospital of UESTC）， a multidisciplinary working group was established. Through literature review and the Delphi method， clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework； systematic searches were conducted in CNKI， Medline， Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment，Development and Evaluation （GRADE） approach， and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations （each with an expert consensus rate exceeding 90%） on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection， dosing ranges， key monitoring points， and safety management strategies for parenteral DTIs in various scenarios， including the perioperative period of ventricular assist device implantation， the perioperative period of cardiac surgery， perioperative patients with lower-extremity atherosclerotic disease， the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome， the perioperative period of carotid artery stenting in patients with carotid stenosis， the perioperative period of patients with right heart thrombosis， and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition， warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus， which is formulated based on the best available evidence， provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

Objective : To establish an enzyme-linked immunosorbent assay (ELISA) for exosome B7-H3 in plas- ma , and to explore the clinical significance and diagnostic value of exosome B7-H3 in plasma from non-small cell lung cancer (NSCLC) . Methods : The plasma of 70 NSCLC patients (NSCLC group) and 36 healthy controls (HC group) were collected . Exosomes and microvesicles in plasma were separated by ultra-fast centrifuge method , and the expression levels of B7-H3 in plasma exosomes in NSCLC groups and HC groups were compared by Western blot method . In NSCLC group , the expression levels of B7-H3 in plasma exosomes and microvesicles in NSCLC group were compared . A simple and feasible ELISA method was established to detect the expression level of exosome B7 - H3 in plasma by means of polyethylene glycol (PEG) precipitation and its clinical significance was analyzed . Lo- gistic regression model was established to predict plasma-derived exosome B7-H3 as a risk factor , and receiver op- erating characteristic curve (ROC) was used to investigate the diagnostic value of exosome B7-H3 in NSCLC . Results: For exosomes and microvesicles in plasma which were extracted by ultracentrifugation , Western blot results showed that the expression level of B7-H3 in plasma exosomes of NSCLC group was higher than that of HC group (P = 0. 032) , and the expression level of B7-H3 in plasma exosomes was higher than that of microvesicles of NSCLC group (P = 0. 012) . The expression level of exosome B7-H3 in plasma extracted by PEG precipitation was also higher in NSCLC group than that in HC group (P = 0. 024) . The expression level of exosome B7-H3 in plasma of NSCLC patients was not related to gender , age , smoking or pathological type , but was related to T stage (P = 0. 002) , N stage (P < 0. 001) , M stage (P = 0. 010) and AJCC stage (P < 0. 001) . Multivariate Logistic regres- sion analysis identified exosome B7-H3 in plasma as a risk factor for NSCLC . ROC analysis showed that the sensi- tivity of exosome B7-H3 in plasma for the diagnosis of NSCLC (0. 843) was higher than that of carcinoembryonic antigen (CEA) (0. 743) , whereas the specificity (0. 722) was lower than that of CEA (0. 833) . Combined de- tection of exosome B7-H3 and CEA (AUC = 0. 928 , 95% CI:0. 877 - 0. 979) had a higher diagnostic performance for NSCLC . Conclusion B7-H3 in plasma exosomes is related to the cancer staging of NSCLC , and the combined detection of exosome B7-H3 and CEA in plasma is conducive to the laboratory diagnosis of NSCLC .

Objective:To investigate the role of a modified positioning device in improving image quality and diagnostic efficacy for thyroid cancer in contrast-enhanced neck CT imaging.Methods:This prospective cross-sectional study included 137 patients with pathologically confirmed thyroid lesions who underwent contrast-enhanced neck CT at Zhangzhou Affiliated Hospital of Fujian Medical University from January to April 2024. Patients scanned in January and February (modified positioning group, n=62) underwent scanning using the modified positioning device, whereas those scanned in March and April (traditional positioning group, n=75) underwent scanning with conventional positioning. The estimated volume CT dose index (CTDI vol) in the thyroid region was recorded. Subjective image quality for thyroid and neck regions was evaluated using a 5-point Likert scale. Diagnostic assessments for thyroid cancer, capsule invasion, and lymph node metastasis were independently conducted by one junior radiologist and one senior radiologist using a 5-point scoring system, with scores≥3 considered positive diagnoses. The differences of CTDI vol and image quality scores between the 2 groups were compared using Mann-Whitney U test. The diagnostic performance was evaluated by the receiver operating characteristic curve analysis. Results:The estimated CTDI vol values for the thyroid region were significantly lower in the modified positioning group compared to the traditional positioning group [11.20 (8.37, 13.56) vs. 12.46 (10.10, 19.43) mGy, Z=1.99, P=0.026]. Subjective image quality scores for thyroid and neck regions were significantly higher in the modified positioning group than in the traditional positioning group (all P<0.001). For thyroid cancer diagnosis by the senior radiologist, the modified positioning group had a significantly higher area under the curve (AUC) of 0.842 (95% CI 0.728-0.956) compared to the traditional positioning group (AUC=0.666,95% CI 0.554-0.777, Z=2.17, P=0.031). No significant differences were observed in diagnostic performance between the junior and senior radiologists for thyroid cancer, capsule invasion, and lymph node metastasis in other subgroup comparisons (all P>0.05). Conclusion:The modified positioning device using in contrast-enhanced neck CT imaging can improve image quality and diagnostic efficacy for thyroid cancer while reducing radiation exposure to the thyroid gland.

Objective:To investigate the characteristics of serum immunoglobulin G (IgG) N-glycans in male patients with different subtypes and severity grades of androgenetic alopecia (AGA) .Methods:A cross-sectional study was conducted on male patients diagnosed with male-pattern hair loss (MPHL) or female-pattern hair loss (FPHL) who attended the Department of Dermatology, Huashan Hospital, Fudan University between June and December 2022. Clinical data were collected, and serum IgG N-glycans were quantitatively analyzed using ultra-performance liquid chromatography (UPLC) . The content of serum IgG N-glycan structures was compared between patients with different AGA subtypes and among patients with different severity grades of MPHL or FPHL, while derived traits were compared between patients with different AGA subtypes. Point-biserial correlation analysis was conducted to assess associations between serum IgG N-glycans and hair loss severity.Results:A total of 85 male patients with AGA were included, comprising 44 MPHL patients and 41 FPHL patients. No significant differences were observed between the two subgroups in terms of age, age at onset, or serum levels of testosterone, sex hormone-binding globulin, uric acid, and 25-hydroxyvitamin D (all P > 0.05) . UPLC showed 23 serum IgG glycans and 5 derived glycan traits (afucosylation, fucosylation, bisecting GlcNAc, terminal galactosylation, and terminal sialylation) . Compared with the MPHL patients, the FPHL patients exhibited significantly increased levels of N-glycans GP5, GP11, GP17, and GP20 (all P < 0.05) , significantly elevated levels of afucosylated IgG N-glycans ( P = 0.047) , but significantly reduced core fucosylated IgG N-glycans ( P = 0.047) . No significant differences in serum IgG N-glycan composition were observed among patients with varying severity grades of MPHL (all P > 0.05) . In the FPHL patients, the levels of N-glycans GP10 ( r = 0.32, P = 0.039) and GP22 ( r = -0.32, P = 0.045) were significantly positively and negatively correlated with hair loss severity respectively; receiver operating characteristic curve analysis showed that both GP10 and GP22 had moderate diagnostic value for predicting hair loss severity, with the area under the curve values being 0.69 (95% CI: 0.52 - 0.86) and 0.71 (95% CI: 0.55 - 0.86) , respectively. Conclusion:Serum IgG N-glycan profiles differed among male patients with different AGA subtypes, and N-glycans GP10 and GP22 may serve as potential biomarkers for early assessment of hair loss severity in male FPHL patients.

This article focuses on analyzing the necessity and appropriateness of growth hormone therapy in children with Kabuki syndrome, and includes a review of relevant literature to improve clinicians′ understanding of this rare condition.

Background: Viral hepatitis causes annual deaths of 1.4 million people. Antiviral therapy rarely cures the disease, and patients are usually required to maintain lifelong medication, leading to cumulative drug toxicity. Schisandrae Fructus (SF) is efficacious in the treatment of viral hepatitis. Objective: The systematic review and meta-analysis aim to examine the efficacy and safety of SF alone or in combination with specific and nonspecific treatments for treating viral hepatitis by analyzing the clinical trials performed up to date. Methods: An extensive literature was searched in 7 databases from inception to May 2023. Final outcomes were divided into the primary outcomes containing the total effective rate and virological responses, as well as the secondary outcomes containing liver biochemical functions and frequencies of adverse events. RevMan 5.3 and GRADE pro 3.6 software were used for meta-analysis and assessment of evidence quality. Subgroup analysis was conducted to explore the source of the heterogeneity. Results: Twenty-nine randomized controlled trials were included in the meta-analysis. SF treatment was comparable with western medicines or other traditional Chinese treatments in terms of primary and secondary outcomes. In combination with specific treatments with antiviral medicines, SF group reduced 18.45 U/L of alanine aminotransferase levels [weighted mean difference: 18.45, 95% confidence interval (CI): (16.12, 20.78), p < 0.000 01] and 8.37 U/L of aspartate aminotransferase levels [weighted mean difference: 8.37, 95% CI: (1.25, 15.48), p = 0.02], and it decreased the levels of hyaluronic acid (HA) [standard mean difference (SMD): 0.92, 95% CI: (0.58, 1.27), p < 0.000 01], laminin (LN) [SMD: 0.64, 95% CI: (0.38, 0.90), p < 0.000 01], and procollagen type III [SMD: 0.48, 95% CI: (0.28, 0.67), p < 0.000 01], while increasing the total effective rate by 24% [risk ratio: 1.24, 95% CI: (1.15, 1.32), p < 0.000 01]. There were no severe adverse events during treatment. Conclusions: SF was a potential adjuvant for antiviral therapy in restoring liver function. However, the poor quality of the included randomized controlled trials limited the recommendations. More long-term, randomized, and double-blind studies should be performed to assess the efficacy and safety of combination therapy.
