Abstract
This paper is the fourth contribution in the Genera of Phytopathogenic Fungi (GOPHY) series. The series provides morphological descriptions and information about the pathology, distribution, hosts and disease symptoms, as well as DNA barcodes for the taxa covered. Moreover, 12 whole-genome sequences for the type or new species in the treated genera are provided. The fourth paper in the GOPHY series covers 19 genera of phytopathogenic fungi and their relatives, including Ascochyta, Cadophora, Celoporthe, Cercospora, Coleophoma, Cytospora, Dendrostoma, Didymella, Endothia, Heterophaeomoniella, Leptosphaerulina, Melampsora, Nigrospora, Pezicula, Phaeomoniella, Pseudocercospora, Pteridopassalora, Zymoseptoria, and one genus of oomycetes, Phytophthora. This study includes two new genera, 30 new species, five new combinations, and 43 typifications of older names. Taxonomic novelties: New genera:Heterophaeomoniella L. Mostert, C.F.J.

Abstract
Lung fibrosis is a serious human pathology. MiR-146b-5p is down-regulated in idiopathic pulmonary fibrosis, and the Notch1/PDGFRβ/ROCK1 pathway is activated. However, the relation between miR-146b-5p and the Notch1/PDGFRβ/ROCK1 pathway in lung fibrosis remains unclear. To investigate the function of miR-146b-5p in lung fibrosis, an in vivo model of lung fibrosis was established in mice by bleomycin. The fibrosis in lung tissues of mice was observed by HE, Masson and Sirius Red staining. Lung pericytes were isolated and identified by fluorescence microscopy. Immunofluorescence staining and Western blot were used to investigate the expression of desmin, NG2, collagen I and α-SMA. CCK8 assay was used to assess the cell viability, and flow cytometry was performed to evaluate the cell cycle in pericytes. Furthermore, the correlation between miR-146b-5p and Notch1 was analysed by Spearman analysis. The mechanism by which miR-146b-5p affects pericytes and lung fibrosis via the Notch1/ PDGFRβ/ROCK1 pathway was explored by RT-qPCR, Western blot, immunofluorescence staining and dual luciferase reporter gene assay. In bleomycin-treated mice, miR-146b-5p was down-regulated, while Notch1 was up-regulated. Up-regulation of miR-146b-5p significantly inhibited the viability and induced G1 phase arrest of lung pericytes. MiR-146b-5p mimics up-regulated miR-146b-5p, desmin, and NG2 and down-regulated α-SMA and collagen I in the lung pericytes. Additionally, miR-146b-5p was negatively correlated with Notch1, and miR-146b-5p interacted with Notch1. Over-expression of miR-146b-5p inactivated the Notch1/PDGFRβ/ROCK1 pathway. Our results indicate that up-regulation of miR-146b-5p inhibits fibrosis in lung pericytes via modulation of the Notch1/PDGFRβ/ROCK1 pathway. Thus, our study might provide a novel target against lung fibrosis.

Abstract
A pedigree genetic analysis of a female Duchenne muscular dystrophy (DMD) inherited from paternal chimerism was conducted to explore the genetic diagnosis strategy. No large deletions/duplications was found in the DMD gene of the proband. Next-generation sequencing (NGS) results showed that the proband had a heterozygous mutation in the DMD gene c.4707C>A (p.C1569X). This locus has not been reported in the literature and is considered as a pathogenic mutation. Sanger sequencing revealed that the father of the proband carried the same mutation, and the mosaic ratio was about 17.7%. The specific enzyme digestion test showed that the proband had maternal skewed X-inactivation. DMD a recessive inherited disease of the X chromosome, exists in female patients, and very few of them are inherited from paternal origin. Female patients need to pay close attention to skewed X-inactivation and suspected new mutations. Mosaic is not excluded, especially the inheritance of paternal mosaicism with normal phenotype. Prenatal gene screening is necessary for reproduction.

Abstract
This study aims to investigate the expression levels and values of autophagy genes light chain 3 (LC3) and autophagy-related 5 (ATG5) in intestinal-type gastric cancer. Ninety samples of normal gastric mucosa, intraepithelial neoplasia, and gastric cancer tissue were used in this study. The messenger ribonucleic acid (mRNA) and protein expression levels of autophagy genes LC3 and ATG5 were detected using quantitative reverse transcription polymerase chain reaction, Western blot, and the immunohistochemistry method. The correlations of the autophagy genes and certain clinical pathological parameters were analyzed. The results showed that LC3 mRNA expression was 43.76 ± 20.31 in the normal group, 111.29 ± 18.65 in the intraepithelial neoplasia group, and 131.78 ± 26.29 in the gastric cancer group, while ATG5 mRNA expression was 4.52 ± 2.37 in the normal group, 7.09 ± 1.88 in the intraepithelial neoplasia group, and 10.25 ± 2.81 in the gastric cancer group. The differences between the groups were statistically significant (P < 0.05). The protein expression of LC3 in the normal group was 1.05 ± 0.41, 1.53 ± 0.36 in the intraepithelial neoplasia group, and 1.99 ± 0.14 in the gastric cancer group. The protein expression of ATG5 was 0.78 ± 0.24 in the normal group, 1.37 ± 0.39 in the intraepithelial neoplasia group, and 2.04 ± 0.63 in the gastric cancer group. The differences between the groups were statistically significant (P < 0.05). The positive rate of LC3 protein expression was 33.3% in the normal group and 60% in the intraepithelial neoplasia group, and the difference was statistically significant (χ2 = 4.89; P = 0.04). In the gastric cancer group, the positive rate of LC3 protein expression was 83.3%, making it significantly higher than the intraepithelial neoplasia group, with a statistically significant difference (χ2 = 4.02, P = 0.045). The positive rate of ATG5 protein expression was 23.3% in the normal group, 50.0% in the intraepithelial neoplasia group, and 76.7% in the gastric cancer group. The expression in the intraepithelial neoplasia group was much higher than in the normal group, with a statistically significant difference (χ2 = 4.59, P = 0.03), and that of the gastric cancer group was much higher than that of the intraepithelial neoplasia group, with a statistically significant difference (χ2 = 4.59, P = 0.03). LC3 protein expression was significantly correlated with depth of infiltration, and lymph node status. ATG5 protein expression was significantly correlated with age, depth of infiltration, and lymph node status. There was also a correlation between the LC3 and ATG5 proteins (correlation coefficient r = 0.72, P = 0.001). The enhanced autophagy activity of LC3 and ATG5 may participate in the occurrence and development of intestinal gastric cancer, and they may play a synergistic role in promoting the occurrence and development of intestinal gastric cancer. These findings provide clinical value for the diagnosis of intestinal gastric cancer.

Abstract
The data of clinical characteristics, medical cost and prognosis of 22 anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis children from the Department of Neurology, Capital Institute of Pediatrics between May 2018 and January 2021 were analyzed, and 6 of them occurred paroxysmal sympathetic hyperactivity syndrome (PSH). It was found that the anti-NMDAR encephalitis children with PSH had severer consciousness disorder [median Glasgow Coma Scale (GCS) score at admission: 7.5], longer duration of consciousness disorder (median time: 53 days), higher hospitalization cost (median cost: 230 000 RMB), severer neurological injury at onset [median modified Rankin Scale (mRS) score at admission: 4], and longer recovery time of neurological function (median time of mRS score recovered to 0-2: 7 months), compared with those without PSH (all P<0.05). Therefore, more attention should be paid to sympathetic excited symptoms of anti NMDAR encephalitis, and thus identify and intervene early on PSH to reduce the neurological damage and economic burden.

Abstract
Histones are important structural proteins of chromatin in the nucleus, which can regulate gene transcription, and can be released from the nucleus to the outside of the cell under injury and inflammatory stimulations, thereby causing cytotoxicity and immune stimulation, and aggravating tissue damage. Extracellular histones are involved in the occurrence and development of many diseases, including sepsis, autoimmune diseases, liver injury, and acute lung injury. Therefore, its application not only can be used as a body's biomarker of inflammation, but also it is expected to become a molecular target for the treatment of diseases. This article reviews the role of extracellular histones in the inflammatory process of liver injury.

Abstract
BACKGROUND In this first-in-human phase 1 study, we investigated the safety and efficacy of the anti-TIGIT antibody vibostolimab as monotherapy or in combination with pembrolizumab. METHODS Part A enrolled patients with advanced solid tumors and part B enrolled patients with non-small cell lung cancer (NSCLC). Patients received vibostolimab 2.1-700 mg alone or with pembrolizumab 200 mg in part A and vibostolimab 200 mg alone or with pembrolizumab 200 mg in part B. Primary end points were safety and tolerability. Secondary end points included pharmacokinetics and objective response rate (ORR) per RECIST v1.1. RESULTS Part A enrolled 76 patients (monotherapy, 34; combination therapy, 42). No dose-limiting toxicities were reported. Across doses, 56% of patients receiving monotherapy and 62% receiving combination therapy had treatment-related adverse events (TRAEs); grade 3-4 TRAEs occurred in 9% and 17% of patients, respectively. The most common TRAEs were fatigue (15%) and pruritus (15%) with monotherapy and pruritus (17%) and rash (14%) with combination therapy. Confirmed ORR was 0% with monotherapy and 7% with combination therapy. In part B, 39 patients had anti-PD-1/PD-L1-naïve NSCLC (all received combination therapy) and 67 had anti-PD-1/PD-L1-refractory NSCLC (monotherapy, 34; combination therapy, 33). In patients with anti-PD-1/PD-L1-naive NSCLC: 85% had TRAEs-the most common were pruritus (38%) and hypoalbuminemia (31%); confirmed ORR was 26%, with responses occurring in both PD-L1-positive and PD-L1-negative tumors. In patients with anti-PD-1/PD-L1‒refractory NSCLC: 56% receiving monotherapy and 70% receiving combination therapy had TRAEs-the most common were rash and fatigue (21% each) with monotherapy and pruritus (36%) and fatigue (24%) with combination therapy; confirmed ORR was 3% with monotherapy and 3% with combination therapy. CONCLUSION Vibostolimab plus pembrolizumab was well tolerated and demonstrated antitumor activity in patients with advanced solid tumors, including patients with advanced NSCLC.

Abstract
Background Bladder cancer (BLCA) is the most prevalent tumor affecting the urinary system, and has contributed to a rise in morbidity and mortality rates. Herein, we sought to identify the methylation-driven genes (MDGs)of BLCA in an effort to develop prognostic biomarkers suitable for the individualized assessment of patients with this particular cancer. Methods The Cancer Genome Atlas (TCGA) dataset was distributed into training set (n=272) and testing set(n=117). The ConsensusClusterPluspackage was used to identify BLCA subtypes. The ChAMP package was used to analyze differential methylation probe (DMP) and differential methylation region (DMR). The differentially expressed genes (DEGs) were detected using DESeq2. Gene Ontology (GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were utilized to identify the pathways enriched of DEGs. Correlation analysis between 5’-C-phosphate-G-3’s (CpGs) and DEGs was employed to identify the MDGs. The Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) was used to build the protein-protein interaction (PPI) network of MDGs. Screening for BLCA prognosis-related MDGs and clinical features was conducted via the Cox regression model. A prognosis-related nomogram was developed and validated for prediction of the BLCA patients’ survival. Results We identified 2 BLCA clusters. Differential methylations at CpGs sites (dm-CpGs) were observed between cluster2 and cluster1, with 14,189 of them hypermethylated and 878 hypomethylated, predominantly in the CpG islands. In addition, a total 4,234 DEGs were identified between cluster2 and cluster1. The KEGG pathway and GO term enrichment analyses found that some DEGs were significantly enriched in multiple cancer-related pathways. A total of 33 MDGs were detected from correlation analysis between CpGs and DEGs. We selected BLCA-specific prognostic DMGs signatures for risk model development. The nomogram comprised a risk model to predict survival for BLCA patients. The efficiency of the prognostic prediction model was validated in the training and testing set. Conclusions This study discovered differential methylation patterns and MDGs in BLCA patients, which provided a bioinformatics basis for guiding BLCA early diagnosis and prognosis analyses.

Abstract
BACKGROUND Patients with chronic rhinosinusitis (CRS) often have Eustachian tube dysfunction (ETD) symptoms. This study aimed to prospectively investigate the effect of endoscopic sinus surgery (ESS) on improvement of Eustachian tube function in CRS patients with ETD from a Chinese population and determine factors associated with improvement. METHODS A prospective study was performed in CRS patients with ETD who underwent ESS from 3 tertiary medical centers in south China. The Eustachian tube Dysfunction Questionnaire 7 (ETDQ-7), Sinonasal Outcome Test 22 (SNOT-22), tympanograms, endoscopic findings and Valsalva maneuver were recorded and analyzed preoperatively and postoperatively at 8-12 weeks. RESULTS A total of 70 CRS patients with ETD were included in this study. The ETDQ-7 score and the ability of positive Valsalva maneuver in CRS patients were significantly improved postoperatively at 8-12 weeks. The number of patients with type A tympanogram was increased postoperatively. Reduced Eustachian tube mucosal inflammation was also observed postoperatively. In addition, ESS appeared to reverse slight tympanic membrane atelectasis after 8-12 weeks. Moreover, improvement in tympanogram was presented in more than half of CRS patients with concomitant otitis media with effusion postoperatively at 8-12 weeks. Univariate and multivariate analysis revealed failure of normalization of ETDQ-7 postoperatively was associated with concomitant allergic rhinitis and higher preoperative SNOT-22 score. CONCLUSIONS This study confirms Eustachian tube function is often improved after ESS in CRS patients with ETD. Concomitant allergic rhinitis and higher preoperative SNOT-22 score are associated with failure of normalization of ETD symptoms.

Abstract
The corrosion resistance of the free surface (FS) and roller surface (RS) of Fe70Si8B12Nb10 amorphous ribbon was systematically compared in simulated seawater (0.6 M NaCl). The electrochemical method and scanning electron microscopy showed that the FS corrosion resistance was higher than that of the RS. XPS etching and Mott–Schottky tests indicated that the passivation films on the FS and RS were divided into outer and inner layers. In the spinning process, the elements with a higher atomic mass tend to segregate toward the FS, while the elements with a lower atomic mass segregate toward the RS. These results provide data that can be used to improve the quality of melt spinning ribbons and to optimize the manufacturing of involved electric devices. The two surfaces of the Fe70Si8B12Nb10 amorphous ribbon have very different corrosion resistances due to different structures.![]()

Abstract
Objective: The main aim of this study was to establish a scoring model to predict risk of progression and survival in patients with regionally recurrent nasopharyngeal carcinoma (NPC). Methods: Three hundred and forty-eight patients subjected to neck dissection from 2003 to 2017 were included for study. Clinicopathologic information for each patient was analyzed. Independent prognostic factors were selected using the Cox proportional hazards model and incorporated into the scoring model. Concordance index (C-index) and calibration curves were used to verify discrimination and calibration, respectively and the results validated using bootstrap resampling. Results: Microscopic positive lymph node > 2 [hazard ratio (HR), 2.19; 95% confidence interval (CI), 1.30–3.68; P = 0.003], extranodal extension (HR, 2.75; 95% CI, 1.69–4.47; P < 0.001), and lower neck involvement (HR, 1.78; 95% CI, 1.04–3.04; P = 0.034) were identified from multivariate analysis as independent factors for overall survival (OS). A qualitative 4-point scale was generated to stratify patients into 4 risk groups for predicting OS and progression-free survival (PFS). The novel scoring model demonstrated enhanced discrimination (C-index = 0.69; 95% CI, 0.62–0.76) relative to the original recurrent tumor-node-metastasis (rTNM) staging system (C-index = 0.56; 95% CI, 0.50–0.62), and was internally validated with a bootstrap-adjusted C-index of 0.70. The calibration curve showed good agreement between predicted probabilities and actual observations. Conclusions: The scoring system established in this study based on a large regionally recurrent NPC cohort fills a gap regarding assessment of risk and prediction of survival outcomes after neck dissection in this population and could be further applied to identify high-risk patients who may benefit from more aggressive intervention.

Abstract
The olfactory system of insects is essential in many crucial behaviors, such as host seeking, mate recognition, and locating oviposition sites. Lepidopteran moths possess two main olfactory organs, including antennae and labial palps. Compared to antennae, the labial palps are relatively specific and worthy of further investigation due to the labial-palp pit organ (LPO), which contains a large number of sensilla located on the tip segment. The fall armyworm, Spodoptera frugiperda, is a worldwide lepidopteran pest, which can damage more than 350 plants and cause significant economic losses. In this study, we surveyed the structure of the labial palps and LPO of S. frugiperda using a super-high magnification lens zoom 3D microscope. Then, the distribution and fine structure of sensilla located in the LPO of S. frugiperda were investigated using scanning electron microscopy. Subsequently, the electrophysiological responses of labial palps to CO2 and 29 plant volatiles were recorded by using electrolabialpalpography. Our results showed the fine structure of labial palps, the LPO, and the sensilla located in the LPO of S. frugiperda. Moreover, we demonstrated that the labial palps are olfactory organs that respond to both CO2 and other volatile compounds. Our work established a foundation for further study of the roles of labial palps in insect olfactory related behaviors. Further investigations on the function of labial palps and their biological roles together with CO2 and volatile compound responses in S. frugiperda are necessary, as they may provide better insect behavioral regulators for controlling this pest.

Abstract
BACKGROUND: Gabapentin and baclofen are recommended for the treatment of chronic refractory cough (CRC). We investigated the efficacy of flupentixol/melitracen in patients unresponsive to these neuromodulators.METHODS: A total of 101 patients with CRC who failed to respond to gabapentin and baclofen were recruited, and treated with flupentixol/melitracen. The prevalence of cough resolution and changes in the Cough Symptom Score (CSS), cough thresholds to capsaicin, Hull Airway Reflux Questionnaire (HARQ), Leicester Cough Questionnaire (LCQ), Generalized Anxiety Disorder-7, Hamilton Anxiety Rating Scale, Patient Health Questionnaire-9, and Hamilton Depression Rating Scale-24 were evaluated after treatment.RESULTS: Ninety-eight patients (97.0%) completed the study. The overall successful cough resolution rate was 62.4% (63/101). Cough resolution was accompanied by an obvious decrease in the CSS and HARQ score and a remarkable increase in cough thresholds to capsaicin challenge and LCQ score, whereas anxiety and depression scores did not change significantly. The prevalence of adverse effects (e.g., insomnia and dizziness) was 21.8%. The prevalence of cough recurrence within 2 weeks after treatment cessation was 17.8%.CONCLUSION: Flupentixol/melitracen may be an efficacious option for CRC unresponsive to other neuromodulators.

Abstract
A series of regulations and policies for Dental Practitioner Qualification were issued during modern times (1906-1949) in China from local to national levels, in which the certification for qualification had been largely based on dental education and training experiences. The present article reviews the evolution and progression of dental practitioner qualification management, as well as its relationship to dental education before 1949, which may hopefully provide a historical background for the development of modern dentistry and enhance the understanding of the current management process for dental practitioner qualifications in China.

Abstract
Objective: To investigate the influencing factors on the vaulting one month after implantable collamer lens (ICL) implantation, and to develop and verify a prediction formula. Methods: The first half of this study was retrospective case series study, and the second half was cross-sectional stydy. A total of 83 eyes of 83 patients who underwent ICL implantation in the Lixiang Eye Hospital of Soochow University were included in the first half of the study, with an average age of (27±5) years, from August 1, 2019 to December 30, 2019. All patients underwent a complete preoperative examination, including axis length, anterior chamber depth, comprehensive optometry, intraocular pressure, central corneal thickness, white-to-white diameter, horizontal and vertical sulcus-to-sulcus diameter (STS), crystalline lens thickness (LT), corneal curvature, and bright and dark pupil diameter. Multiple linear regression (stepwise) was used to develop a prediction formula. In the validation part, a total of 65 people (65 eyes) were included, with an average age of (26±5) years, from March 1, 2020 to June 1, 2020. The accuracy and reliability of the formula were verified by the intergroup correlation coefficient and Bland-Altman consistency test. Results: At 1 month after surgery, ICL size had the greatest impact on the vaulting (β=0.942, P<0.001), followed by horizontal STS (β=-0.517, P<0.001), LT (β=-0.376, P<0.001), and vertical STS (β=-0.257, P=0.017). The influence of other factors was not statistically significant (all P>0.05). The regression equation was as follows: the vaulting (μm)=-1 369.05+657.12×ICL size-287.41×horizontal STS-432.50×LT-137.33×vertical STS (the fitting degree R=0.813, R2=0.660, and corrected R2=0.643). In the verification part, the predicted average vaulting was (497.31±102.75) μm, while the actual vaulting was (514.62±152.99) μm. About 96.92% (63/65) of the patients were fitted in the moderate vault, and 3.08% (2/65) were in the high vault. The intergroup correlation coefficient was 0.581. According to the Bland-Altman test, the actual vaulting was 17.31 μm, higher than the predicted value, and the 95% confidence interval of the difference was -260.28 to 294.90 μm. Conclusion: The ICL size, horizontal and vertical STS and LT are the factors that affect and predict the vaulting one month after ICL implantation, and our prediction formula has good accuracy and reliability.

Abstract
Odorant receptors (ORs) are essential for plant–insect interactions. However, despite the global impacts of Lepidoptera (moths and butterflies) as major herbivores and pollinators, little functional data are available about Lepidoptera ORs involved in plant-volatile detection. Here, we initially characterized the plant-volatile-sensing function(s) of 44 ORs from the cotton bollworm Helicoverpa armigera, and subsequently conducted a large-scale comparative analysis that establishes how most orthologous ORs have functionally diverged among closely related species whereas some rare ORs are functionally conserved. Specifically, our systematic analysis of H. armigera ORs cataloged the wide functional scope of the H. armigera OR repertoire, and also showed that HarmOR42 and its Spodoptera littoralis ortholog are functionally conserved. Pursuing this, we characterized the HarmOR42-orthologous ORs from 11 species across the Glossata suborder and confirmed the HarmOR42 orthologs form a unique OR lineage that has undergone strong purifying selection in Glossata species and whose members are tuned with strong specificity to phenylacetaldehyde, a floral scent component common to most angiosperms. In vivo studies via HarmOR42 knockout support that HarmOR42-related ORs are essential for host-detection by sensing phenylacetaldehyde. Our work also supports that these ORs coevolved with the tube-like proboscis, and has maintained functional stability throughout the long-term coexistence of Lepidoptera with angiosperms. Thus, beyond providing a rich empirical resource for delineating the precise functions of H. armigera ORs, our results enable a comparative analysis of insect ORs that have apparently facilitated and currently sustain the intimate adaptations and ecological interactions among nectar feeding insects and flowering plants.

Abstract
Abstract Objective To study the imaging characteristics of maxillary sinus effusion in drowned bodies, to explore its morphological characteristics and value in the diagnosis of the cause of death, and to provide objective evidence to support the study of virtual anatomy of drowning. Methods The 154 postmortem CT examination cases (31 cases of drowning, 123 cases of non-drowning) of Beijing Public Security Bureau Forensic Center in 2019 were collected. The bodies of all cases were scanned by multi-layer spiral CT before double-blind reading by clinical imaging experts. Maxillary sinus of corpses with maxillary sinus effusion in imaging findings was punctured. The detection rate of maxillary sinus effusion was calculated. The CT value and volume of maxillary sinus effusion were measured on 3D DICOM workstation. Results The detection rate of maxillary sinus effusion in the drowning was 100%, the shape was horizontal liquid level, the volume was 1.2-11.2 mL, the CT value was 6.08-19.02 Hu, with an average value of 12.85 Hu. The detection rate of maxillary sinus effusion in non-drowning was 19.51% (24/123), the shape was wavy or irregular, and there were bubbles inside, the volume was 0.4-13.4 mL, the CT value was 23.68-77.75 Hu, with an average value of 42.08 Hu. The differences in CT value between the two groups had statistical significance. Conclusion The postmortem CT examination method can be used to observe the shape and measure the CT value of the maxillary sinus effusion in the bodies in water, which can be an auxiliary examination method for identification of drowning.

Abstract
OBJECTIVE To investigate the effect of fatty acid synthase (FASN) gene silencing on lipid metabolism and biological behaviors of human hepatoblastoma HepG2 cells. OBJECTIVE Small interfering RNA (siRNA) targeting FASN gene or a negative control siRNA sequence (NC-siRNA) was transfected into HepG2 cells, and the gene silencing efficiency was evaluated with qRT-PCR and Western blotting. Triglyceride level in the cells was detected using enzyme-linked immunosorbent assay, and Oil red O staining was performed to examine intracellular lipid droplets. The proliferation ability of the transfected cells was tested by CCK-8 assay, and cell apoptosis was evaluated using annexin V-FITC/PI apoptosis detection kit. Wound healing assay and Transwell assay were performed to assess the migration ability of the transfected cells. OBJECTIVE Transfection of the cells with FASN-siRNA, but not NC-siRNA, significantly lowered FASN expression at both the mRNA and protein level (P < 0.001) and decreased the number of lipid droplets (P < 0.001) and triglyceride level (P < 0.01) in the cells. FASN gene silencing significantly inhibited proliferation, increased apoptosis rate and suppressed migration of HepG2 cells (P < 0.001). OBJECTIVE FASN gene silencing inhibits proliferation and migration and promotes apoptosis of HepG2 cells possibly by suppressing lipid synthesis in the cells.

Abstract
OBJECTIVE Several studies have reported that the controlling nutritional status (CONUT) score is a prognostic predictor for survival among patients with different types of cancer. We assessed the prognostic value of changes in the CONUT score during treatment and the ΔCONUT-EBV DNA score in patients with advanced nasopharyngeal carcinoma (NPC). METHODS We retrospectively analyzed 433 patients with advanced NPC having no evidence of metastasis from January 2007 to June 2011; the patients underwent radical concurrent chemoradiotherapy (CCRT) at Sun Yat-sen University Cancer Center and were grouped based on their ΔCONUT and ΔCONUT-EBV DNA scores. Kaplan-Meier curves were used to compare the patient outcomes according to the cut-off ΔCONUT score and the ΔCONUT-EBV DNA scoring system. RESULTS Among all patients, overall survival (OS) was independently predicted by a high ΔCONUT score (P = 0.031) and high EBV DNA (P < 0.001). The ΔCONUT-EBV DNA score [OS area under the curve (AUC) = 0.621; progression free survival (PFS)-AUC = 0.612; distant metastasis-free survival (DMFS)-AUC = 0.622] was more predictive of OS, PFS, and DMFS in patients with advanced NPC than the ΔCONUT score (OS-AUC = 0.547; PFS-AUC = 0.533; DMFS-AUC = 0.522) and pretreatment plasma EBV DNA levels alone (OS-AUC = 0.600; PFS-AUC = 0.591, DMFS-AUC = 0.610). The ΔCONUT-EBV DNA score was significantly correlated with OS, PFS, and DMFS in patients with advanced NPC treated with CCRT. CONCLUSIONS The ΔCONUT-EBV DNA score may be useful in clinical practice as a convenient biomarker for predicting the outcomes in patients with advanced NPC treated with CCRT.

Abstract
Objective: To understand the capacity building needs on social organizations providing HIV prevention and treatment services for female sex workers (FSW). Methods: Questionnaires and interview were conducted with the heads of social organizations participating in China AIDS Fund for Non-Governmental Organizations (CAFNGO) project 2017-2018. Data from the CAFNGO's information system were compiled and analyzed using Excel 2016 and SPSS 25.0 software. The distribution of social organizations, availability of funds, and social organizations' needs for capacity building were analyzed. Results: Nationwide, 184 social organizations were involved in project '2017-2018 CAFNGO's FSW field work'. Out of which, 156 answers were valid. Social organizations that participated in the implementation of fund projects were mainly concentrated in the western region, accounting for 44.0% (81/184), with Sichuan, Guangxi, and Yunnan being the majority. However, the eastern part received the most financial support. Social organizations expressed the highest demand for project data collection and analysis, accounting for 68.6% (107/156). Items on risk analysis, response, and quality control project ranked the second, accounting for 64.1% (100/156). Results showed that statistically significant differences were seen on capacity building needs among social organization leaders with different levels of training on management of planning and finance of the project (χ2=5.78,P=0.016;χ2=8.99,P=0.003). Conclusions: Currently, the number of social organizations and the related fund provision concerning HIV prevention and control among FSWs were not consistent in China. Thus, it is necessary to encourage, guide, and support the development of social organizations and satisfy social organizations' needs on capacity-building and planning.

Abstract
To explore the technical process and the therapeutic effect of using sequential surgical guide with independent intellectual property rights assisting immediate implantation and restoration of the full arch, with the support from the periodontal splint for mobile supporting teeth, patients with severe periodontitis who planned to undergo immediate full arch implantation were recruited from August 2019 to December 2020 at the Department of Prosthodontics, Department of Periodontology, Department of Implantology and First Clinical Division, Peking University School and Hospital of Stomatology. Through the procedure of collecting preoperative maxillofacial data, making systematic diagnostic design, making periodontal splints fixation, producing surgical guide, and carrying out guided surgery for full arch immediate implantation, eight cases were included. By registering the postoperative cone-beam CT (CBCT) with the preoperative data, the difference between the actual three-dimensional position of the implants and the virtual design was observed, and the accuracy of the implant placement position guided by the sequential guide was statistically analyzed using SPSS 25.0 software. Analysis indicators include coronal and apical global displacement, coronal horizontal and vertical displacement, apical horizontal and vertical displacement, and angular deviation. Results revealed that the 8 patients [2 males and 6 females, aged (49.0±9.3) years (38-65 years)] of recruited cases included 7 cases of maxilla and 1 cases of mandible. A total of 48 implants, of which 44 implants were placed upright and 4 were placed tilted, 16 implants in the anterior region and 32 implants in the posterior region. No guide plate fracture or damage to important anatomical structures were reported. The overall displacement at the coronal point [(0.83±0.48) mm] and the global displacement at the apical point [(1.36±0.57) mm] were within the clinically acceptable safety range, and the horizontal displacement and vertical displacement at the coronal point, horizontal displacement and vertical displacement at the apical point, and the angle deviation of implants axial have no statistic significant difference in the anterior and posterior region (P>0.05). Periodontal splints combined with sequential surgical guides to assist patients with severe periodontitis for immediate full arch implantation and immediate restoration can expand the indications of guide assisted implant surgery. It meets the safety requirements in clinical applications.

Abstract
Objective: To explore the visual fixation patterns during facial emotion recognition and the association between fixation duration percentage (FDP) of eye region with social impairment among high-functioning autism spectrum disorders (HFASD). Methods: Children were recruited from the Child and Adolescent Behavior Research Center of Sun Yat-sen University, Guangzhou, between July and December 2019 for case control study. A total of 42 children with HFASD and 23 age-and gender-matched typical development (TD) children were enrolled. Based on their performance during the facial emotion recognition task, HFASD children were further divided into ASD-1 group (correctly recognized both happy and fear emotions) and ASD-2 group (recognized happy emotions only). During the free viewing task, an infrared eye tracker was used to record the gazing data of children in the three groups. The social responsiveness scales (SRS) was utilized to evaluate HFASD children's social impairment, with the cutoff score of 75 to differentiate those from mild and severe social impairment. The differences of FDP among the three groups were analyzed by the Analysis of Variance (ANOVA) model. Mixed linear regression model was conducted to evaluate the associations between social impairment and FDP of eye region among HFASD children. Results: The final sample consists of 25 ASD-1 (20 males, aged (7.9±1.0) years), 17 ASD-2(14 males, aged (7.2±1.2) years), and 23 TD (12 males, aged (7.7±1.3) years) children. There were no significant differences in age and gender among three groups (F=2.05, χ²=10.08, P=0.14 and 0.07, respectively). For the happy emotion, there are significant differences in eye FDP among the three groups (TD: 0.37±0.20, ASD-1: 0.35±0.20, ASD-2: 0.47±0.24, F=3.97, P=0.02). Mixed linear regression model revealed that, adjusting for emotion, gender, age and intelligence quotient, ASD children's eye FDP negatively associates with social impairment (OR=0.15, 95%CI: 0.06-0.35, P<0.01). Conclusions: Longer FDP is associated with milder social impairment among HFASD children. HFASD children with facial emotion recognition difficulties require longer fixation to recognize happy emotions.

Abstract
Few studies have examined the association of serum selenium with anemia-related indicators and risk of anemia. We conducted a cross-sectional analysis of 2,902 adults in 2003-2004 National Health and Nutrition Examination Survey database. Multivariable linear and logistic regression models were used to examine the association of serum selenium with anemia-related indicators and risk of anemia. The nonlinear relationship was analyzed using a generalized additive model with the smoothing plot. A total of 1,472 males and 1,430 females with a mean age of 61.94 ± 13.73 years were included. Compared with the lowest quintile, the highest quintile of serum selenium was associated with increased level of serum iron (β = 12.44, 95% confidence interval [CI]: 7.14, 17.75, p < .001), mean corpuscular hemoglobin concentration (MCHC) (β = 0.14, 95%CI: 0.02, 0.26, p = .020), and hemoglobin (β = 0.40, 95%CI: 0.19, 0.61, p < .001), and decreased risk of anemia (odds ratio [OR] = 0.47, 95%CI: 0.28, 0.77, p = .002). Furthermore, smoothed plots suggested the nonlinear relationships between serum selenium and MCHC, hemoglobin level, and risk of anemia. Interestingly, on the left of inflection point, serum selenium was associated with decreased risk of anemia (OR = 0.972, 95%CI: 0.960, 0.985, p < .001), and then, the risk of anemia increased with increasing serum selenium concentration (OR = 1.011, 95%CI: 1.002, 1.021, p = .023). Future large-scale, polycentric prospective studies should be conducted to verify our results.

Abstract
It is unclear whether residual anterograde pulmonary blood flow (APBF) at the time of Fontan is beneficial. Pulsatile pulmonary flow may be important in maintaining a compliant and healthy vascular circuit. We, therefore, wished to ascertain whether there was hemodynamic evidence that residual pulsatile flow at time of Fontan promotes clinical benefit. 106 consecutive children with Fontan completion (1999-2018) were included. Pulmonary artery pulsatility index (PI, (systolic pressure-diastolic pressure)/mean pressure)) was calculated from preoperative cardiac catheterization. Spectral analysis charted PI as a continuum against clinical outcome. The population was subsequently divided into three pulsatility subgroups to facilitate further comparison. Median PI prior to Fontan was 0.236 (range 0-1). 39 had APBF, in whom PI was significantly greater (median: 0.364 vs. 0.177, Mann-Whitney p < 0.0001). There were four early hospital deaths (3.77%), and PI in these patients ranged from 0.214 to 0.423. There was no correlation between PI and standard cardiac surgical outcomes or systemic oxygen saturation at discharge. Median follow-up time was 4.33 years (range 0.0273-19.6), with no late deaths. Increased pulsatility was associated with higher oxygen saturations in the long term, but there was no difference in reported exercise tolerance (Ross), ventricular function, or atrioventricular valve regurgitation at follow-up. PI in those with Fontan-associated complications or the requiring pulmonary vasodilators aligned with the overall population median. Maintenance of pulmonary flow pulsatility did not alter short-term outcomes or long-term prognosis following Fontan although it tended to increase postoperative oxygen saturations, which may be beneficial in later life.

Type of funding sources: None.
Background
Ablation of para-hisian accessory pathways (APs) remains challenging due to anatomic characteristics and few studies have focused on the causes for recurrence of radiofrequency ablation of para-hisian APs.
Objective
This retrospective single center study was aimed to explore the risk factors for recurrence of para-hisian APs.
Methods
113 patients who had a para-hisian AP with an acute success were enrolled in the study. In the 11-year follow-up, 15 cases had a recurrent para-hisian AP. Therefore 98 patients were classified into success group while 15 patients were classified into recurrence group. Demographic and ablation characteristics were analyzed.
Results
Gender difference was similar in two groups. The median age was 36.2 years old and was younger in recurrence group. Maximum ablation power was significantly higher in success group (29 ± 7.5 vs 22.9 ± 7.8, p < 0.01). Ablation time of final target sites was found to be markedly higher in success group (123.4 ± 53.1 vs 86.7 ± 58.3, p < 0.05). Ablation time less than 60 seconds was detected in 12 (12.2%) cases in success group and 7 (46.7%) cases in recurrence group (p < 0.01). Occurrence of junctional rhythm was significantly higher in recurrence group (25.5% vs 53.3%, p < 0.05). No severe conduction block, no pacemaker implantation and no stroke were reported. Junctional rhythm during ablation (OR = 3.833, 95%CI 1.083-13.572, p = 0.037) and ablation time <60s (OR = 5.487, 95%CI 1.411-21.340, p = 0.014) were independent risk factors for the recurrence of para-hisian AP.
Conclusions
Considering the long-term safety of ablation of para-hisian AP, proper extension of ablation time and increase of ablation power could be applied during operation.

Abstract
PURPOSE The aim of this study was to design and fabricate a three-dimensional (3D) printed artificial ovary. METHODS We first compared the printability of gelatin-methacryloyl (GelMA), alginate and GelMA-alginate bioinks, of which GelMA was selected for further investigation. The swelling properties, degradation kinetics and shape fidelity of GelMA scaffolds were characterized by equilibrium swelling/lyophilization, collagenase processing and micro-computed tomography evaluation. Commercial ovarian tumor cell lines (COV434, KGN, ID8) and primary culture ovarian somatic cells were utilized to perform cell-laden 3D printing, and the results were evaluated by live/dead assays and TUNEL detection. Murine ovarian follicles were seeded in the ovarian scaffold and their diameters were recorded every day. Finally, in vitro maturation was performed, and the ovulated oocytes were collected and observed. RESULTS Our results indicated that GelMA was suitable for 3D printing fabrication. Its scaffolds performed well in terms of hygroscopicity, degradation kinetics and shape fidelity. The viability of ovarian somatic cells was lower than that of commercial cell lines, suggesting that extrusion-based 3D culture fabrication is not suitable for primary ovarian cells. Nevertheless, the GelMA-based 3D printing system provided an appropriate microenvironment for ovarian follicles, which successfully grew and ovulated in the scaffolds. Metaphase II oocytes were also observed after in vitro maturation. CONCLUSIONS The GelMA-based 3D printing culture system is a viable alternative option for follicular growth, development and transfer. Accordingly, it shows promise for clinical application in the treatment of female endocrine and reproductive conditions.

Abstract
Thirty mice were used to establish a sepsis model with cecal ligation and puncture. 15 mg/kg methylene blue or isotonic saline were injected intraperitoneally to observe liver tissue pathological changes. Changes in macrophage frequency and expressional condition of M1 and M2-type hepatic inflammatory factors were detected. After LPS stimulation, the expression level of macrophage inflammatory factor were detected. The results showed that the pathological liver injury was significantly reduced in the MB mice group (P < 0.05), and the frequency of liver macrophage was not statistically significantly different (P > 0.05). MB elevation had promoted the expression of M2-type hepatic inflammatory factor (P < 0.05) and macrophage inflammatory factor (P < 0.05). MB can play a role in preventing septic liver injury by inducing macrophages polarization to M2-type.

Abstract
Gastrointestinal motility was disturbed in W/Wv, which were lacking of interstitial cells of Cajal (ICC). In this study, we have investigated the role of arecoline hydrobromide (AH) on smooth muscle motility in the jejunum of W/Wv and wild-type (WT) mice. The jejunum tension was recorded by an isometric force transducer. Intracellular recording was used to identify whether AH affects slow wave and resting membrane potential (RMP) in vitro. The whole-cell patch clamp technique was used to explore the effects of AH on voltage-dependent potassium channels for jejunum smooth muscle cells. AH enhanced W/Wv and WT jejunum contractility in a dose-dependent manner. Atropine and nicardipine completely blocked the excitatory effect of AH in both W/Wv and WT. TEA did not reduce the effect of AH in WT, but was sufficient to block the excitatory effect of AH in W/Wv. AH significantly depolarized the RMP of jejunum cells in W/Wv and WT. After pretreatment with TEA, the RMP of jejunum cells indicated depolarization in W/Wv and WT, but subsequently perfused AH had no additional effect on RMP. AH inhibited the voltage-dependent K+ currents of acutely isolated mouse jejunum smooth muscle cells. Our study demonstrate that AH enhances the contraction activity of jejunum smooth muscle, an effect which is mediated by voltage-dependent potassium channels that acts to enhance the excitability of jejunum smooth muscle cells in mice.

Abstract
Objective: To investigate the clinicopathological features, immunophenotype, and differential diagnosis of adenocarcinoma of the rete testis. Methods: Four adenocarcinoma cases of the rete testis diagnosed at West China Hospital, Chengdu, China (3 cases, including 2 consultation cases) and the First Affiliated Hospital of Fujian Medical University, Fuzhou, China (1 case) between January 2009 and December 2017 were included. Their clinical, morphologic and immunohistochemical features were analyzed using histological analysis and immunohistochemical staining. Related literature was reviewed to reveal the characteristics of this tumor. Results: The 4 patients' age range was 26-64 years. The maximum diameters of the tumors were 3.0 and 4.5 cm in 2 cases, respectively. On gross examination, adenocarcinomas of the rete testis appeared as a solid, white to gray or tan to yellow mass that raised at the hilum of the testis. Microscopically, all tumors showed multiple histologic patterns, including corded/trabecular (4/4), glandular, nested, sarcomatoid (3/4), solid (2/4), papillary, cribriform, and slit-like (1/4). Three types of adenocarcinoma cells included cuboidal to columnar (4/4), polygonal (4/4) and spindle-shaped (2/4) with pale eosinophilic and clear cytoplasm. The tumor cell nuclei appeared moderately to markedly atypical and pleomorphic, with a various number of mitoses. Transition from benign to malignant rete epithelium was seen in all cases. Eosinophilic hyaloid globules were found in 1 case. On immunohistochemical study, the tumor cells were diffusely, strongly positive for CKpan (4/4), EMA (4/4), Ber-EP4 (3/3) and CAⅨ(2/2), and focally positive for CK7 (4/4), vimentin (4/4), CD10 (4/4), PAX8 (3/3), PAX2 (3/3). The Ki-67 proliferative index was all>50% (4/4). The prognosis was poor. Two of the 3 patients died within 1 year after the surgical resection. Conclusions: Adenocarcinoma of the rete testis is a rare malignant tumor with several histologic patterns. Transition from benign to malignant rete epithelium is an important diagnostic clue. Detailed clinical history, tumor growth site and immunohistochemistry are helpful for its diagnosis and differential diagnosis.

Abstract
Research into the development of sustainable biomaterials is increasing in both interest and global importance due to the increasing demand for materials with decreased environmental impact. This research field utilises natural, renewable resources to develop innovative biomaterials. The development of sustainable biomaterials encompasses the entire material life cycle, from desirable traits, and environmental impact from production through to recycling or disposal. The main objective of this review is to provide a comprehensive definition of sustainable biomaterials and to give an overview of the use of natural proteins in biomaterial development. Proteins such as collagen, gelatin, keratin, and silk, are biocompatible, biodegradable, and may form materials with varying properties. Proteins, therefore, provide an intriguing source of biomaterials for numerous applications, including additive manufacturing, nanotechnology, and tissue engineering. We give an insight into current research and future directions in each of these areas, to expand knowledge on the capabilities of sustainably sourced proteins as advanced biomaterials.

Abstract
Background Cigarette smoking constitutes a major lifestyle risk factor for osteoporosis and hip fracture. It is reported to impair the outcome of many clinical procedures, such as wound infection treatment and fracture healing. Importantly, although several studies have already demonstrated the negative correlation between cigarette consume and impaired bone homeostasis, there is still a poor understanding of how does smoking affect bone health, due to the lack of an adequately designed animal model. Our goal was to determine that cigarette smoke exposure impairs the dynamic bone remodeling process through induction of bone resorption and inhibition of bone formation. Methods We developed cigarette smoke exposure protocols exposing mice to environmental smoking for 10 days or 3 months to determine acute and chronic smoke exposure effects. We used these models, to demonstrate the effect of smoking exposure on the cellular and molecular changes of bone remodeling and correlate these early alterations with subsequent bone structure changes measured by microCT and pQCT. We examined the bone phenotype alterations in vivo and ex vivo in the acute and chronic smoke exposure mice by measuring bone mineral density and bone histomorphometry. Further, we measured osteoclast and osteoblast differentiation gene expression levels in each group. The function changes of osteoclast or osteoblast were evaluated. Results Smoke exposure caused a significant imbalance between bone resorption and bone formation. A 10-day exposure to cigarette smoke sufficiently and effectively induced osteoclast activity, leading to the inhibition of osteoblast differentiation, although it did not immediately alter bone structure as demonstrated in mice exposed to smoke for 3 months. Cigarette smoke exposure also induced DNA-binding activity of nuclear factor kappaB (NFκB) in osteoclasts, which subsequently gave rise to changes in bone remodeling-related gene expression. Conclusions Our findings suggest that smoke exposure induces RANKL activation-mediated by NFκB, which could be a “smoke sensor” for bone remodeling.

Abstract
AIM To evaluate the association between perihaematomal radiomics features and haematoma expansion (HE). MATERIALS AND METHODS Clinical and radiological data were collected retrospectively. The 1:1 propensity score matching (PSM) method was used to balance the difference of baseline characteristics between patients with and without HE. Radiomics features were extracted from the intra- and perihaematomal regions. Top HE-associated features were selected using the minimum redundancy, maximum relevancy algorithm. Support vector machine models were used to predict HE. Predictive performance of radiomics features from different regions was evaluated by receiver operating characteristic curve and confusion matrix-derived metrics. RESULTS A total of 1,062 patients were enrolled. After PSM analysis, the propensity score-matched cohort (PSM cohort) included 314 patients (HE: n=157; non-HE: n=157). The PSM cohort was distributed into the training (n=218) and the validation cohorts (n=96). The predictive performance of intra- and perihaematomal features were comparable in the training (area under the receiver operating characteristic curve [AUC], 0.751 versus 0.757; p=0.867) and the validation cohorts (AUC, 0.724 versus 0.671; p=0.454). By incorporating intra- and perihaematomal features, the combined model outperformed the single intrahaematomal model in the training cohort (AUC, 0.872 versus 0.751; p<0.001). Decision curve analysis (DCA) further confirmed the clinical usefulness of the combined model. CONCLUSION Perihaematomal radiomics features can predict HE. The integration of intra- and perihaematomal signatures may provide additional benefit to the prediction of HE.

Abstract
Objective: To develop a color-moment based model for frozen-section diagnosis of thyroid lesions, and to evaluate the model's value in the frozen-section diagnosis of thyroid cancer. Methods: In this study, 550 frozen thyroid pathological slides, including malignant and non-malignant cases, were collected from Taizhou Central Hospital (Taizhou University Hospital), China, between June 2018 and January 2020. The 550 digitalized frozen-section slides of thyroid were divided into training set (190 slides), validation set (48 slides), test set A (60 slides) and test set B (252 slides). The tumor regions on the slides of malignant cases in the training and validation sets were labeled by pathologists. The labeling information was then used to train the thyroid frozen-section diagnosis models based on the voting method and those based on the color moment. Finally, the performance of two pathological slide diagnosis models was evaluated using the test set A and test set B, respectively. Result: The classification accuracy of the thyroid frozen-section diagnosis model based on the voting method was 90.0% and 83.7%, using test sets A and B, respectively, while that based on color moments was 91.6% and 90.9%, respectively. For actual frozen-section diagnosis of thyroid cancer, the model developed in this study had higher accuracy and stability. Conclusion: This study proposes a color-moment based frozen-section diagnosis model, which is more accurate than other classification models for frozen-section diagnoses of thyroid cancer.

Abstract
OBJECTIVE Long non-coding RNA taurine upregulated gene 1 (lncRNA TUG1) has been demonstrated to promote malignant phenotypes and Adriamycin resistance in acute myeloid leukemia (AML) cells. However, the function and mechanism of TUG1 in cytarabine (Ara-C) sensitivity in AML remain unclear. PATIENTS AND METHODS Levels of TUG1, microRNA (miR)-655-3p or cyclin D1 (CCND1) mRNA were examined using quantitative real-time polymerase chain reaction (qRT-PCR). Cell proliferation activity and apoptosis were analyzed using cell counting kit-8 (CCK-8) or flow cytometry, respectively. Western blot was utilized to detect the protein levels of Ki-67, B-cell lymphoma-2-associated X protein (Bax), and CCND1. The interaction between miR-655-3p and TUG1 or CCND1 was confirmed by Dual-Luciferase reporter and pull-down assay. RESULTS TUG1 and CCND1 were higher expressed, while miR-655-3p was lower expressed in AML cells compared with that in normal cells. Higher expression levels of TUG1 or CCND1, and lower expression levels of miR-655-3p both notably reversed Ara-C-induced proliferation inhibition and apoptosis promotion in AML cells. TUG1 was a sponge of miR-655-3p, and TUG1 knockdown enhanced the sensitivity of AML cells to Ara-C by regulating miR-655-3p. MiR-655-3p directly targeted CCND1, and CCND1 overexpression attenuated miR-655-3p restoration-mediated reinforcement of Ara-C sensitivity in AML cells. Besides that, TUG1 up-regulated CCND1 expression via miR-655-3p. CONCLUSIONS TUG1 weakened the sensitivity of AML cells to Ara-C by up-regulating CCND1 via miR-655-3p, suggesting a new insight into the chemotherapy of AML.

Abstract
Abstract Death after carotid sinus trauma is usually attributed to death from inhibition, a type of sudden death. Currently, the number of incidents is scarce, and related studies are few. Therefore, how to determine the involvement of carotid sinus and determine the role of diseases in the cause of death has always been a difficult point in forensic investigation. This article sorts out the research literature on carotid sinus related death at home and abroad in recent years, systematically reviews the anatomic structure of the carotid sinus nerve, the clinical epidemiology of carotid sinus syndrome, and the research on the death mechanism of carotid sinus injury at home and abroad in recent years, in order to provide references for forensic pathology research and prosecution.
