AIM:To investigate the effect of plate-let(PLT)on angiogenesis in hepatocellular carcino-ma and the intervention effect of Cinobufagin(CBG).METHODS:Firstly,we screened the suitable co-incubation ratio of PLT and hepatocellular carci-noma cells,prepared conditioned medium,and de-termined the half inhibitory concentration of Cinob-ufagin;then,we set up a control group(human um-bilical vein endothelial cells(EC)+conventional me-dium),a crosstalk group(EC+CM_HP(strip culture prepared by crosstalk of HUH7 and PLT)),and an in-tervention group(EC+CM_HP+CBG).The migration,tube-formation and sprouting capacity of EC and the level of vascular endothelial growth factor(VEGF)in co-cultured supernatant were evaluated by scratch assay,tube-formation assay,budding as-say and ELISA assay.Western blot was used to de-tect the expression of VEGFR2 and p-VEGFR2,and reverse verification was performed with inhibitors.A subcutaneous transplantation tumour model of hepatocellular carcinoma in nude mice was estab-lished,with Model group,Model+CBG group and Model+Apa group.The collagen expression of the transplantation tumour was observed by Masson staining,and the expression levels of vascular endo-thelial markers CD31 and CD34 were detected by immunofluorescence.RESULTS:When PLT:HUH7=200,the activity of HUH7 was the strongest,and the crosstalk between HUH7 and PLT significantly promoted the proliferation of EC(P＜0.01).Com-pared with Control group,the migration,tube-for-mation and budding ability of Crosstalk group were enhanced,and those of Intervention group were lower than those of Crosstalk group(P＜0.01).The expression level of VEGF in the supernatant of Crosstalk group was higher than that of Control group,while that of Intervention group was lower than that of Crosstalk group(P＜0.01).The expres-sion level of p-VEGFR2 protein in Crosstalk group was significantly higher than that of Control group,but the expression level of Intervention group was lower than that of Crosstalk group(P＜0.01).Large collagen fibre deposition was seen in the Model group,and CBG intervention significantly reduced collagen fibre deposition in the transplanted tu-mour tissues.CD31 and CD34 expression was pres-ent in the hepatocellular carcinoma transplanted tumour tissues in the Model group,and CBG inter-vention significantly reduced the expression of CD31 and CD34 in the liver cancer transplanted tu-mour tissues(P＜0.01).CONCLUSION:PLT enhances angiogenesis in hepatocellular carcinoma,and CBG may inhibit its tube-forming ability via the VEGF/VEGFR2 pathway.

Objective:To investigated the prevalence of anxiety and depression symptoms in patients with colorectal polyps in part of Xinjiang area and to explore the associated influencing factors related to psychological status, and to provide evidence and clues to promote the diagnosis and treatment of psychosomatic diseases in digestive system.Methods:From December 2021 to June 2022, at the First Affiliated Hospital of Shihezi University, the Fourth Division Hospital of Xinjiang Production and Construction Corps, the Third Division Hospital of Xinjiang Production and Construction Corps (Kashgar Hospital), the Thirteenth Division Red Star Hospital of Xinjiang Production and Construction Corps, the Tenth Division Beitun Hospital of Xinjiang Production and Construction Corps, the Seventh Division Hospital of Xinjiang Production and Construction Corps, the Fifth Division Hospital of Xinjiang Production and Construction Corps, patients who underwent colonoscopy and colorectal polyps detected were enrolled. The generalized anxiety disorder scale-7 (GAD-7) was used to screen anxiety symptoms, and the patient health questionaire-8 (PHQ-8) was performed to screen depression symptoms, and the general situation questionnaire was used to collect clinical information of patients. The questionnairs were completed via the Questionnaire Star platform or paper questionnaire, and a database was established. The patients were divided into groups according to whether with anxiety and depression symptoms. Multivariable logistic regression models was performed to analyze the factors related to anxiety and depression.Results:A total of 516 questionnaires were distributed and collected, among which 9 questionnaires were incomplete and 507 questionnaires were valid, the effective rate of questionnaires was 98.26%. The detection rates of anxiety and depression symptoms in 507 patients with colorectal polyps were 21.50%(109/507) and 19.33%(98/507), respectively. The results of multivariable logistic analysis revealed that female ( OR=3.87, 95% confidence interval (95% CI) 2.30 to 6.51, P<0.001), maximum diameter of polyp ( OR=1.74, 95% CI 1.14 to 2.67, P=0.011), perception of polyps as cancer ( OR=13.96, 95% CI 1.48 to 132.07, P=0.022), and the occurrence of gastrointestinal symptoms after polyp detection ( OR=5.43, 95% CI 1.74 to 16.92, P=0.004) were independent risk factors of anxiety in patients with colorectal polyps. Female ( OR=2.42, 95% CI 1.47 to 4.00, P=0.001), the number of polyps ( OR=1.07, 95% CI 1.01 to 1.13, P=0.028) and the count of gastrointestinal symptoms ( OR=2.04, 95% CI 1.34 to 3.10, P=0.001) were independent risk factors of depression in patients with colorectal polyps. Conclusion:Gender, polyp size, number of polyps, disease perception, and concomitant gastrointestinal symptoms are associated with anxiety and depression in patients with colorectal polyps.

Objective Exposure to nocturnal traffic noise at the same levels can produce different effects on sleep and psychological health in different populations. This study compared the electroencephalographic characteristics during sleep of people with insomnia and those with normal sleep quality under the same levels of nocturnal traffic noise exposure to elucidate the different effects of noise pollution on different populations,and to provide individualized precise treatment plans for people with insomnia who are sensitive to noise pollution. Methods We selected people who lived near highways,railways,and aircraft routes for more than six months where noise levels were relatively fixed(50-60 decibels,10-15 seconds per time) during the nighttime sleep period (22:00-6:00). We included 26 people with normal sleep quality and 30 people with insomnia based on the Pittsburgh Sleep Quality Index. The Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were administered. Polysomnography (PSG) was used to monitor the spindle density index during sleep. The sleep quality and psychological status of the two groups were compared. Results There were no significant differences in demographic characteristics between the two groups under the same nocturnal noise exposure conditions. The incidence of anxiety and depression was significantly lower in the people with normal sleep quality than in those with insomnia(P<0.01). Among the 26 people with normal sleep quality,5(19.23%) had mild anxiety,and no one had moderate to severe anxiety or depression. Among the 30 people with insomnia,6(20.00%) had mild anxiety,15 (50.00%) had moderate anxiety,and 4(13.33%) had severe anxiety;3(10.00%) had mild depression,9(30.00%) had moderate depression,and 3(10%) had severe depression. PSG showed that the sleep spindle index of the normal sleep group was significantly higher than that of the insomnia group(25.43 vs 16.60,P<0.05),with no significant differences in the average duration of sleep spindles during sleep between the two groups (P>0.05). Conclusion Under the same levels of nocturnal traffic noise exposure,people with insomnia have a higher incidence of anxiety and depression than people with normal sleep quality. Patients with insomnia with a reduced spindle density index have worse sleep quality under exposure to noise pollution.

Brassica juncea is a yearly or biennial vegetable in Brassica of Cruciferae. The yield and quality of its product organs are affected by flowering time. WRKY proteins family can respond to biological and abiotic stresses, developmental regulation and signal transduction. WRKY75 is an important member of WRKY family which can regulate flowering, but the flowering regulation mechanism in B. juncea has not been reported. In this study, a gene BjuWRKY75 in B. juncea was cloned, and the encoded-protein belonged to the group Ⅱ of WRKY protein with highly conserved domain. BjuWRKY75 had the highest homology with BriWRKY75 of Brassica nigra. The relative expression level of BjuWRKY75 in flowers was significantly higher than that in leaves and stems, and it was expressed stably in leaves. BjuWRKY75 protein was localized in the nucleus and interacted with the promoter of the flowering integrator BjuFT, which contained the W-box response element for the interaction between protein and DNA. Thus, it could transcriptionally activate the expression of the downstream genes. The overexpression of BjuWRKY75 in Arabidopsis led to earlier flowering significantly. In conclusion, BjuWRKY75 could directly target the promoter of BjuFT and accelerate flowering. These results may facilitate further study on the regulation of flowering molecules of BjuWRKY75.

Objective: To investigate the clinical value of combined detection of serum angiopoietin 2 (Ang-2) and Clara cell protein 16 (CC16) in the early diagnosis of acute respiratory distress syndrome (ARDS). Methods: Two hundred critical patients, treated at the Department of Critical Care Medicine, Bao'an District People's Hospital, Shenzhen during March 2015 and September 2016,were included in the study. According to the Berlin standard, patients were divided into two groups (n=100 each group): the ARDS group and non-ARDS group.The serum levels of Ang-2 and CC16 were measured by enzyme-linked immunosorbent assay (ELISA) on the first and second day of admission for each patient, in addition to completing APACHEⅡ score, medical history, vital signs collection and other biochemical indicators detection. Finally, paired-samples t test was used to analyze the data. The multiple ROC curve was used to calculate the area under the curve of the reference index of the serum levels of Ang-2 and CC16 on the first and second day. Results: On the first and second day, the serum levels of Ang-2 and CC16 were significantly higher in ARDS patients than those in non-ARDS patients, and there was a correlation between the serum levels of Ang-2 and CC16 in ARDS patients. The ROC curve showed that the combined detection of Ang-2 and CC16 on the first day achieved a highest sensitivity of 75.9% and detection of CC16 on the first day achieved a highest specificity of 70.2%. Conclusion Single-detection of serum levels of Ang-2 and CC16 could be used for early diagnosis of ARDS, and the combined detection of both has a higher sensitivity than single detection.
