[Objective]To explore the occurrence of gasdermin D(GSDMD)-mediated pyroptosis and its effect on cell proliferation,migration and tubular formation abilities of synovial vascular endothelial cells(VEC)in rheumatoid arthritis(RA).[Methods]Synovium tissues from knee joints of 22 RA patients and 18 orthopaedic arthropathies(Orth.A)patients were collected.The level of activated GSDMD-NT segment in synovium was detected by Western blot.The clinical characteristics of RA patients were compared between high and low synovial GSDMD-NT groups.The cell localization of GSDMD in RA synovium was detected by immunofluorescence staining.RA synovial fluid was added to the culture of human umbilical vein endothelial cells(HUVEC)in vitro,and the level of apoptosis and expression of pyroptosis pathway proteins were detected.The effects of GSDMD on apoptosis,proliferation,migration and tubule formation of HUVEC cells were analyzed.[Results]GSDMD expression in RA synovium was significantly higher than that in Orth.A,and more severe joint destruction and higher microvascular count score were found in RA patients with high GSDMD-NT expression.Synovial VEC had positive expression of GSDMD.Stimulation with RA synovial fluid could induce GSDMD-mediated pyroptosis in HUVEC,increased the secretion of vascular endothelial growth factor(VEGF)and their abilities of proliferation,migration and tubule formation.Knockdown of GSDMD could reverse the above effects.[Conclusion]GSDMD-mediated pyroptosis of partial synovial VEC aggravates RA joint destruction through VEGF secretion that promotes proliferation,migration and angiogenesis of the remaining VEC,which may be a new target to block neovascularization and inhibit joint destruction in RA.

To promote the construction of a wound repair and regeneration system with Chinese characteristics, it is necessary to follow the principle of combining traditional Chinese and Western medicine, and integrate theory, clinical practice, and teaching. Traditional Chinese medicine emphasizes a holistic concept and the principle of dialectical treatment, while Western medicine focuses on etiological analysis and local treatment. The combination of Chinese and Western medicine can complement each other's advantages and improve treatment effectiveness. The key technological innovations in repairing and regenerating systems cover areas such as drug therapy, physical therapy, and the application of biomaterials. This article discusses the development potential and challenges of combining traditional Chinese and Western medicine in the field of wound repair and regeneration, providing new ideas and methods for the development of wound repair and regeneration. It is expected to bring better medical services and treatment effects to patients undergoing repair and regeneration.

Purpose:
From the perspective of positive psychology, our study aimed to explore depressive symptomsand psychological well-being among Chinese nurses, as well as analyze the impacts of characterstrengths, self-efficacy and social support on the mental health of nurses.
Methods:
A cross-sectional and descriptive design using five self-reported questionnaires was used toinvestigate a cohort of 4238 nurses during 2018. A structural equation modeling analysis was used toverify a hypothetical model linking character strengths, self-efficacy, social support, depressive symptoms,and psychological well-being.
Results:
The prevalence of depression among this cohort of Chinese nurses was 58.1%. The mean scoresfor caring, inquisitiveness, and self-control were 19.93 (SD = 2.82), 15.94 (SD = 3.00), and 16.34(SD = 2.95), respectively. The hypothesized model was a good fit of the data (x2/df = 1.77, p = .183, rootmean square error of approximation = 0.04, goodness of fit index = 1.00, comparative fit index = 1.00,TuckereLewis index = 1.00). Except for the path from self-control to depression, the other hypotheticalpaths investigated were statistically significant.
Conclusion
Character strengths were directly and positively associated with psychological well-being.Inquisitiveness was the strongest direct protective factor for depression. In addition, characterstrengths indirectly alleviated depression and increased psychological well-being through mediatingvariables of social support and self-efficacy. This study should alert nurse managers that more attentionshould be paid to the character strengths and mental health of nurses. This study provides evidence forinterventions based on character strengths as a management strategy to support the mental health ofnurses.

Objective To investigate DSA- estimated hepatic arterial hemodynamics of hepatocellular carcinoma (HCC) determined shortly after transcatheter arterial chemoembolization (TACE) plus sorafenib treatment. Methods The clinical data of thirty HCC patients treated with TACE were retrospectively analyzed. The patients were divided into study group (n = 13) and control group (n = 17). Patients in the study group received additional oral administration of 400mg sorafenib twice a day one week before or two weeks after TACE procedure, while patients in the control group received TACE only. The initial DSA images as well as the images obtained at three months after TACE were analyzed. With the help of Photoshop software, the grey gradient of the tumor staining was measured on the series dynamic DSA images, based on which the time- density curve of the tumor was drawn. The peak density value (PV), the time to reach the peak (TP) and the slope of the upslope (SU) were determined, and the results were compared between the two groups. Results Photoshop software was used to measure the grey density values of the tumor staining on DSA images. In the study group, the post- treatment PV was smaller than the pre- treatment one, which were (38.0 ± 14.6) and (46.7 ± 18.4) respectively, the difference between the two groups was statistically significant (P = 0.040). The post- treatment PV of the study group was also smaller than that of the post -treatment PV of the control group (54.4 ± 19.8), and the difference between the two was also statistically significant (P = 0.011). No significant differences in TP values and SU values existed between the two groups as well as between the pre - treatment and post - treatment ones in each group. Conclusion After TACE.

OBJECTIVETo investigate the regulation mechanism of apoptosis induced by the antisense bcl-2 treatment.
METHODSDNA content analysis and terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) were adopted to detect apoptosis. Semi-quantitative reverse transcription-PCR was performed to detect the mRNA expression of bcl-2 c-myc survivin bax s100A(2) TNFalpha TGFbeta(1) and IL-6 in the small-cell lung cancer cell line NCI-H446 treated with antisense bcl-2 oligodeoxynucliotide.
RESULTSbcl-2 AS-PS-ODN treatment could induce apoptosis, accompanied with 72.71% up-regulation of IL-6 and 65.90% down-regulation of TNFalpha, whereas little or no effect was seen on c-myc survivin bax s100A(2) and TGFbeta(1).
CONCLUSIONIL-6 and TNFalpha may be involved in the regulation of apoptosis induced by antisense bcl-2 treatment.
