Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

Objective To investigate the anti-atherosclerotic mechanism of herbal cake-separated moxibustion.Methods Twenty-four New Zealand purebred male rabbits were randomly divided into normal group,model group,herbal cake-separated moxibustion group and Atorvastatin group,with 6 rabbits in each group.Except for the normal group,the rabbits in the other groups were fed with high-fat diet mixed with Propylthiouracil(PTU)method to construct an atherosclerosis model.At the same period of modeling,corresponding intervention was given.After 12 weeks,the levels of serum total cholesterol(TC),triglyceride(TG)and low density lipoprotein cholesterol(LDL-C)were detected.The pathological changes of rabbit aortic tissue were observed by hematoxylin-eosin(HE)staining.The levels of serum tumor necrosis factor α(TNF-α),interleukin 6(IL-6)and interleukin 10(IL-10)were detected by enzyme-linked immunosorbent assay(ELISA).The contents of phosphatidylinositol 3-kinase(PI3K),phosphorylated protein kinase B(p-AKT)and phosphorylated mammalian target of rapamycin(p-mTOR)in myocardial tissue were detected by Western Blot.Results Compared with the normal group,the serum levels of TC,TG and LDL-C in the model group were significantly increased(P＜0.001),the aortic vascular endothelial structure was significantly damaged,the serum levels of TNF-α and IL-6 were increased(P＜0.001),the serum level of IL-10 was decreased(P＜0.01),and the protein expression levels of PI3K,p-AKT and p-mTOR in myocardial tissue were significantly decreased(P＜0.05 or P＜0.01).Compared with the model group,the above indexes in the herbal cake-separated moxibustion group and the Atorvastatin group were significantly improved(P＜0.05 or P＜0.01 or P＜0.001).Compared with the Atorvastatin group,the contents of TG and LDL-C in the herbal cake-separated moxibustion group were increased(P＜0.01),and other indicators did not change significantly(P＞0.05).Conclusion The mechanism of anti-atherosclerosis of herbal cake-separated moxibustion may be related to the activation of PI3K/AKT/mTOR signaling pathway and the regulation of the expressions of inflammatory mediators TNF-α,IL-6 and IL-10.

Objective: To understand the status of autism spectrum disorder (ASD) cohort studies and explore the feasibility of constructing ASD disease-specific cohorts based on real-world data (RWD). Methods: ASD cohort studies published by December 2022 were collected by literature retrieval from major Chinese and English databases. And the characteristics of the cohort were summarized. Results: A total of 1 702 ASD cohort studies were included, and only 60 (3.53%) were from China. A total of 163 ASD-related cohorts were screened, of which 55.83% were birth cohorts, 28.22% were ASD-specific cohorts, and 4.91% were ASD high-risk cohorts. Most cohorts used RWD such as hospital registries or conducted community-based field surveys to obtain participant information and identified patients with ASD by scales or clinical diagnoses. The contents of the studies included ASD incidence and prognostic risk factors, ASD comorbidity patterns and the impact of ASD on self-health and their offspring's health. Conclusions: ASD cohort studies in developed countries have been in the advanced stage, while the Chinese studies are still in their infancy. RWD provides the data basis for ASD-specific cohort construction and offers new opportunities for research, but work such as case validation is still needed to ensure the scientific nature of cohort construction.

Objective:To develop a method to quantify nine constituents in different medicinal parts of Pimpinella thellungiana, in order to compare the content difference of the nine constituents, namely protocatechuic acid,gallic acid,neochlorogenic acid,chlorogenic acid,cryptochlorogenic acid,luteolin-7-O-β-D-glucuronide,isochlorogenic acid A,apigenin-7-O-β-D-glucuronide and isochlorogenic acid C. Method:The analysis was performed on an Agilent TC-C₁₈ column (4.6 mm×250 mm,5 μm) with acetonitrile and mixed acid solution (0.1% phosphoric acid-0.1% glacial acetic acid) as mobile phase for gradient elution. The handover detection wavelengths were at 265 and 325 nm. The column temperature was 20℃, and the flow rate was 1.0 mL·min^-1. The experiment data was analyzed using the software of Markerlynx XS. Result:The nine constituents of protocatechuic acid,gallic acid,neochlorogenic acid,chlorogenic acid,cryptochlorogenic acid, luteolin-7-O-β-D-glucuronide,isochlorogenic acid A,apigenin-7-O-β-D-glucuronide and isochlorogenic acid C had a good degree of separation and a good linearity in their respective linear ranges(r>0.999 8). The average recoveries ranged from 99.11% to 100.76%,and the RSD ranged from 0.9% to 2.0% 。The results showed that the contents of the nine constituents had significant differences in different medicinal parts of P. thellungiana. The average contents of the nine constituents were the highest in leaves,which was followed by stem,and the lowest was in root. Conclusion:The study could provide evidence for the quality control,clinical application,and scientific resources utilization of P. thellungiana.

Introduction:Thrombocytosis has been identified as an unfavorable prognostic factor in several types of cancer. This study aimed to evaluate the prognostic value of pretreatment platelet count in association with the TNM staging system and therapeutic regimens in patients with nasopharyngeal carcinoma (NPC). Methods:A total of 2,626 patients with NPC were retrospectively analyzed. Platelet count>300 × 109/L was defined as thrombocytosis. Matched-pair analysis was performed between patients receiving chemoradiotherapy and radiotherapy. Results:Multivariate analysis showed that platelet count was an independent unfavorable prognostic factor for overal survival (OS) [hazard ratio (HR)=1.810, 95%confidence interval (CI)=1.531–2.140, P<0.001] and distant metastasis–free survival (DMFS) (HR=1.873, 95%CI=1.475–2.379, P<0.001) in the entire patient cohort. Further subgroup analysis revealed that increased platelet count was an independent unfavorable prognostic factor for OS and DMFS in patients with NPC stratified by early and advanced T category, N category, or TNM classification (al P≤0.001). Receiver operating characteristic (ROC) curves verified that the predictive value of TNM classification for OS was improved when combined with pretreatment platelet count (P=0.030). Matched-pair analysis showed that chemoradiotherapy significantly improved OS only in advanced-stage NPC with thrombocytosis (HR=0.416, 95%CI=0.226–0.765, P=0.005). Conclusions:Pretreatment platelet count, when combined with TNM classification, is a useful indicator for metastasis and survival in patients with NPC. It may improve the predictive value of the TNM classification and help to identify patients likely to benefit from more aggressive therapeutic regimens.

AIM:To elucidate whether ZFP580 is involved in the cardioprotective effects of hypoxic precondi-tioning (HPC) against hypoxia-reoxygenation (H/R) injury in H9c2 myocardial cells.METHODS: Rat heart-derived H9c2 cells were cultured in DMEM .H/R was induced by incubation under ischemic hypoxia for 3 h and reoxygenation for 2 h.HPC was induced by exposing the H 9c2 cells to 10 min of hypoxia and 20 min of reoxygenation for 3 cycles before H/R treatment.MTT staining and LDH leakage detection were used to evaluate the effects of HPC .Western blotting was used to detect the protein levels of ZFP580, phosphorylated ERK1/2 and cleaved caspased-3.The effects of ZFP580 overexpre-ssion or knockdown on H/R induced apoptosis were determined .RESULTS:The results of MTT staining and LDH leakage detection showed evidence of HPC cytoprotection against H /R-induced cell death in H9c2 cells.ZFP580 protein level and ERK1/2 phosphorylation were significantly increased in the HPC group compared with control group and H /R group. PD98059, an inhibitor of ERK1/2 phosphorylation , significantly suppressed the HPC-induced up-regulation of ZFP580 pro-tein expression.ZFP580 overexpression significantly inhibited apoptosis and caspase-3 activation in H9c2 cells.CON-CLUSION:HPC exhibits cytoprotection against H/R and leads to high level of ZFP 580 protein in H9c2 cells.ZFP580 is regulated by ERK1/2 activation and mediates the anti-apoptotic effect of the ERK1/2 signaling pathway in HPC cytoprotec-tion.
