Objective To investigate the effect of β-arrestin1(ARRB1)on cell proliferation,migration and invasion in oral squamous cell carcinoma(OSCC).Methods Based on The Cancer Genome Atlas(TCGA)database,the expression profiles of ARRB1 in OSCC were analyzed,and then Gene Set Enrichment Analysis(GSEA)was used to suggest the possible signaling pathways involved,and to explore its potential impact on the prognosis of OSCC patients.Immuinohistochemistry(IHC)was performed to detect the expression of ARRB1 in OSCC tumor tissues and adjacent tissues,and the correlation between ARRB1 expression and clinicopathological features was statistically analyzed.The expression profiles of ARRB1 in SCC-15,CAL-27 and HOK cell lines were verified by qPCR and Western blotting.The ARRB1 overexpression plasmid model was constructed,and its effects on the proliferation,migration and invasion of OSCC cells were analyzed by clone formation,EdU,scratch and Transwell assays.Results TCGA showed that the expression level of ARRB1 was significantly lower in head and neck squamous cell carcinoma(HNSC)and OSCC tissues than the corresponding normal tissues(P<0.01).The expression of ARRB1 in OSCC tissues was correlated with tumor differentiation,lymph node metastasis and TNM stage(P<0.05).The OSCC patients with high expression of ARRB1 had a lower survival rate than those with low expression(P<0.01),which was consistent with the results of bioinformatics analysis.The expression level of ARRB1 in SCC-15 and CAL-27 cells was lower than that of HOK cells(P<0.01),and its overexpression significantly inhibited cell proliferation(P<0.05),migration(P<0.01)and invasion(P<0.01).Conclusion ARRB1 is lowly expressed in OSCC,its overexpression inhibits the proliferation,migration and invasion of OSCC cells,and it is related to prognosis improvement.

Objective:To explore the expression of 7-dehydrocholesterol reductase (DHCR7) in gastric cancer using bioinformatics methods and its relationship with clinical pathological characteristics and prognosis of gastric cancer patients.Methods:DHCR7 expression in gastric cancer was analyzed using the UALCAN database; DHCR7 mRNA expression and its relationship with the prognosis of gastric cancer patients were analyzed using the Kaplan-Meier plotter database; The expression of DHCR7 and its correlation with tumor immune infiltration level were analyzed using Sangerbox 3.0 and TIMER database; Real-time fluorescence quantitative PCR was used to detect the expression of DHCR7 mRNA in gastric cancer tissues and adjacent tissues; immunohistochemical staining was conducted to detect the DHCR7 expression in gastric cancer tissues and adjacent tissues and its correlation with clinical pathological parameters; Receiver operator characteristic (ROC) curve was used to evaluate the efficacy of DHCR7 expression in the diagnosis of gastric cancer.Results:The analysis results of the UALCAN database showed that there were statistically significant differences in DHCR7 mRNA expression among gastric cancer patients of different genders ( χ2=18.15, P<0.001), grades ( χ2=16.32, P<0.001), and TP53 mutation status ( χ2=20.12, P<0.001). Survival analysis showed that the 10-year overall survival (OS) rate ( HR=1.55, 95% CI: 1.31-1.84, P<0.001), 10-year progression free survival (PFS) rate ( HR=1.67, 95% CI: 1.36-2.05, P<0.001), and 10-year post progression survival (PPS) rate ( HR=1.81, 95% CI: 1.43-2.28, P<0.001) of gastric cancer patients with high DHCR7 expression were significantly lower than those with low DHCR7 expression. Immune infiltration analysis showed the expression of DHCR7 was negatively correlated with the comprehensive score ( r=-0.51, P<0.001), stromal cell score ( r=-0.48, P<0.001), immune cell score ( r=-0.45, P<0.001), CD4 + T cells ( r=-3.01, P<0.001), macrophages ( r=-0.40, P<0.001), neutrophils ( r=-0.32, P<0.001), and dendritic cells ( r=-0.37, P<0.001) infiltration levels in gastric cancer, and positively correlated with the purity of gastric cancer cells ( r=0.15, P<0.001). The qRT-PCR results showed that compared with adjacent tissues (1.86±0.51), the expression of DHCR7 in gastric cancer tissues (3.43±0.13) was significantly upregulated, with a statistically significant difference ( t=42.89, P<0.001). The relative expression level of DHCR7 in normal gastric mucosal cells GES-1 was 1.06±0.19, and the relative expression levels in four types of gastric cancer cells (HGC-27, AGS, SNU-1, and SGC-7901) were 2.40±0.26, 1.88±0.11, 1.51±0.04, and 2.63±0.20, respectively, there were statistically significant differences in the expression of DHCR7 among the five types of cells ( F=38.34, P<0.001), and the relative expression level of DHCR7 in normal gastric mucosal cells was statistically significant different compared to the four types of gastric cancer cells mentioned above ( P=0.002; P=0.003; P=0.017; P<0.001) ; The immunohistochemical results showed that the high expression rate of DHCR7 in gastric cancer tissues was 80.0% (96/120), which was significantly higher than that in adjacent tissues (68.3%) (82/120) ( χ2=56.84, P<0.001). There were statistically significant differences in tumor maximum diameter ( χ2=40.17, P<0.001), histological grade ( χ2=16.20, P<0.001) and pTNM stage ( χ2=16.99, P<0.001) between patients with high and low DHCR7 expression. The ROC curve results showed that the area under the curve (AUC) of DHCR7 expression level for diagnosing gastric cancer were 0.76 (based on TCGA database, 95% CI: 0.68-0.83, P<0.001) and 0.97 (120 clinical samples of gastric cancer, 95% CI: 0.95-0.99, P<0.001), respectively. Conclusions:DHCR7 is highly expressed in gastric cancer and closely associated with poor prognosis in patients, which may be a novel biomarker for the diagnosis and prognosis of gastric cancer.

Objective:To evaluate the effect of the right stellate ganglion block (SGB) on the acute lung injury induced by hind limb ischemia-reperfusion (I/R) in rats.Methods:Twenty-seven SPF healthy male Sprague-Dawley rats, aged 7-8 weeks, weighing 200-250 g, were divided into 3 groups ( n=9 each) by the random number table method: sham operation group (Sham group), hind limb I/R group (I/R group) and right SGB+ hind limb I/R group (SGB+ I/R group). The right hind limb I/R injury model was developed in anesthetized rats in I/R and SGB+ I/R groups, and the right SGB was performed with 0.2% ropivacaine 0.5 ml before the right hind limb ischemia in SGB+ I/R group. The pathological changes of lung tissues were observed with a light microscope, the wet/dry lung weight ratio, PaO 2 and PaCO 2 were determined, and the oxygenation index was calculated. The concentrations of serum malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) were determined using enzyme-linked immunosorbent assay. Results:Compared with Sham group, the wet/dry lung weight ratio, PaO 2, oxygenation index, and GSH-Px concentrations were significantly decreased, and the concentrations of serum MDA were increased in I/R and SGB+ I/R groups ( P<0.05). Compared with I/R group, the wet/dry lung weight ratio, PaO 2, oxygenation index, and GSH-Px concentrations were significantly increased, the concentrations of serum MDA were decreased ( P<0.05), and the pathological changes of lung tissues were significantly attenuated in SGB+ I/R group. There was no significant difference in PaCO 2 among the 3 groups ( P>0.05). Conclusions:The right SGB can alleviate the acute lung injury induced by hind limb I/R, and the mechanism may be related to the inhibition of oxidative stress responses in rats.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

Objective:To investigate the clinical characteristics and diagnostic approach of patients with high-level fall injuries combined with chest trauma.Methods:A retrospective analysis was conducted on 137 patients who sought medical treatment at Suzhou Dushu Lake Hospital (Dushu Lake Hospital Affiliated to Soochow University) between December 2020 and June 2023. These patients had sustained injuries from high-level falls with concurrent chest trauma. Among them, there were 87 male individuals with an average age of (40.44±10.23) years and 27 female individuals with an average age of (36.92±10.75) years. Among the patients, 114 met the inclusion criteria, while 23 were excluded. The clinical characteristics and treatment outcomes were analyzed based on the Revised Trauma Score and chest trauma score in order to further investigate the trauma characteristics of patients with high-level fall injuries and enhance the efficiency of diagnosis, treatment, and clinical outcomes.Results:There was a negative linear correlation between the Revised Trauma Score and chest trauma score in patients with high-level fall injuries combined with chest trauma. Chest trauma, requiring comprehensive management throughout the entire course of the disease, emerged as a significant independent factor affecting clinical prognosis. In the RTS severe injury group, the proportion of severe chest injuries or multiple injuries in patients with high-level fall injuries was 59/68 (86.76%), with 47/68 (69.11%) of patients experiencing concomitant head injuries, 25/68 (36.76%) experiencing abdominal organ injuries, 58/68 (85.29%) experiencing limb or spinal fractures, and 26/68 (38.23%) having other types of injuries. In the RTS mild injury group, the proportion of severe chest injuries or multiple injuries was 17/46 (36.95%), with 17/46 (36.95%) of patients experiencing concomitant head injuries, 8/46 (17.39%) experiencing abdominal organ injuries, 17/46 (36.95%) experiencing limb or spinal fractures, and 11/46 (23.91%) having other types of injuries.Conclusion:Patients with high-level fall injuries are prone to multiple chest injuries or injuries in other regions, exhibiting complex and variable injury patterns. Particularly in the RTS severe injury group, the incidence of severe chest injuries or concomitant injuries in the chest or other regions is significantly higher compared to the RTS mild injury group. Therefore, comprehensive management of chest trauma should be prioritized throughout the clinical diagnosis and treatment process to further improve patient prognosis.

  Objective  To evaluate the clinical and paraclinical features of Chinese patients with anti- LGI1 encephalitis.  Methods  Patients with memory deficits, psychiatric symptoms, seizures or altered level of consciousness, suspicious of encephalitis, at presentation to Peking Union Medical College Hospital were recruited between July 2013 and January 2018, and tested for anti-LGI1 antibodies in their serum and/or cerebrospinal fluid(CSF) samples. Patients with anti-LGI1 antibodies were enrolled. The demographic characteristics, clinical manifestations, laboratory examination results, neuroimaging features, immunotherapy, follow-up practices and outcomes for included patients were registered and analyzed.  Results  The study enrolled 120 patients, of whom 66.7% were male. The median age was 61 years (interquartile range [IQR]: 49-66 years). Seizures(65.0%) were the most common initial symptoms. Most patients developed seizures (95.0%), including faciobrachial dystonic seizures (54.2%), memory deficits (92.5%), and psychiatric symptoms (69.1%). Brain MRI and ¹⁸F-FDG PET / CT showed that the lesions were mainly located in unilateral or bilateral medial temporal lobes, and (or) basal ganglia. Of the patients, 95.0% received intravenous immunoglobulin (IVIg) or corticosteroids, 47.5% received mycophenolate mofetil as long-term immunotherapy, and no one received second-line immunotherapy. The median follow-up was 34.2 months(IQR: 22.0-45.6 months). 91.2% had a good outcome (modified Rankin Scale score≤2 points). Residual mild memory deficits were present in 47.8% of the patients. Nine deaths were documented. Relapses occurred in 24.8% of the patients in the first year. In total, 24 (20%)cases were young patients(onset age ≤45 years).There were fewer males among the younger patients(37.5% vs. 74.0%, P < 0.01). Besides, there were fewer younger patients with psychiatric symptoms(50.0% vs. 74.0%, P=0.02), hyponatremia(33.3% vs. 68.8%, P < 0.01), and abnormalities on brain ¹⁸F-FDG PET/CT(20.8% vs. 47.9%, P=0.02). The relapse-free survival rate was significantly higher in the young patients.  Conclusions  Elderly males were predominant in patients with anti-LGI1 encephalitis. Most patients developed symptoms of limbic encephalitis and/or FDBS during the disease course. Several patients were young adults and lacked typical symptoms. Neuroimaging features were consistent with the involvement of limbic system or basal ganglia. Patients with anti-LGI1 encephalitis respond well to immunotherapy, irrespective of the age.

Objective To evaluate the efficacy of endoscopic ultrasound guided biliary drainage (EUS-BD) in patients with biliary obstruction and surgically altered anatomies.Methods We collected data from 33 patients with biliary obstruction and surgically altered anatomies from January 2016 to January 2018 in Zhejiang University School of Medicine Affiliated Hangzhou First People's Hospital who underwent EUS-guided biliary drainage after unsuccessful ERCP.The operation success rate,clinical success rate,complication rate,hospital stay were studied.Results Of 33 patients,31 were successfully operated and stented using endoscopic ultrasound puncture:14 patients through the stomach,17 patients through the duodenum;8 patients by the rendezvous approach.The operation success rate was 93.9％.Of the 33 patients,28 had a significant decrease in jaundice,with a clinical success rate of 84.9％.Complications consisted of 2 patients with bleeding and 1 patient with cholangitis.These patients improved after conservative treatment.The complications rate was 9.1％.The hospital stay was (12.4±5.7) d.Conclusion EUS-BD can be the first choice for patients with biliary obstruction and surgically altered anatomy after failed endoscopic retrograde cholangiograohv in centers with exoertise in EUS-BD procedures.

Objective To evaluate the efficacy of bare mental stent (BMS) and covered stent (CS) in the treatment of complete central venous occlusive disease (CVOD) in hemodialysis patients.Methods A total of 66 cases of CVOD who have been treated by endovascular methods successfully in the First Affiliated Hospital of Sun Yat-sen University from Jan 2015 to Jan 2017 were enrolled in this study.According to the type of stent,the patients were divided into two groups,BMS group (n=46)and CS group (n=20).The demographic data,clinical signs and symptoms,and pre-procedure and post-procedure imaging data were followed up and recorded.The primary patency rates were calculated at 1,3,6,9,and 12 months.Results The related symptoms were improved within 2 day post-procedure.The primary patency rates of BMS group in 1,3,6,9 and 12 months were 97.83％,95.65％,69.56％,41.3％,and 34.78％ respectively.The rates of CS group were 100％,100％,95％,65％,and 60％respectively.They did not reached statistical significance for primary patency rates between two groups in 1,3,and 6 months (P ＞ 0.05 respectively).However,from 9 months after procedure,it began to show the significant difference between two groups (P ＜ 0.05).The median patency time of the CS group was (10.30±5.32) months,while BMS group was (8.52±0.49) months.The difference between the two groups was statistically significant (P=0.046).Conclusions Stent implantation for complete occlusion of central venous in hemodialysis patients can get credible effect.The use of CS for CVOD provides superior patency as well as patency time in long period after procedure as compared with BMS.

Objective: To understand the current situation and the relationship between the health literacy of primary school teachers and health behavior literacy of students, and to provide some inspiration for the reform of health promotion and education in school. Methods: Twelve primary schools were selected from Jintai district, Chencang district and Long county，and we used stratified cluster random sampling method to choose 334 primary school teachers and 622 students of grade 4 and 6 to fill out the questionnaire. Results: Nearly 46.71% of all the teachers had adequate health literacy. Multivariate Logistic regression analysis showed that the urban and rural (OR=2.30, 95%CI=1.30-4.07) and gender (OR=2.62, 95%CI=1.36-5.05) were statistically significant for the health literacy among teachers; Adequate health behavior literacy was found in 46.78% of all the students，multivariate Logistic regression analysis also showed the urban and rural (OR=2.07, 95%CI=1.33-3.24）and mother’s education (OR=2.01-2.41, 95%CI=1.25-4.76) were statistically significant. Spearman correlation coefficient between health literacy of the teachers and students was(r=0.69, P<0.05). Conclusion The relation between health literacy of the teachers and students is positive. To improve the health literacy of primary school students, health literacy of primary school teachers should be improved first in China.
