Objective·To investigate the effects of a novel chitosan-silver nitrate gel (CSNG) dressing on anti-septic in wound healing.Methods·By using the ion membrane,the release rate of the new composite materials of silver ion was tested in vitro.Meanwhile,the anti-septic effects of CSNG on methicillin resistant Staphylococcus aureus (MRSA),Escherichia coli and Candida albicans were tested by colony counting.The rat wound healing model was used to detect the ability of new material to kill MRSA in vivo.Results·Compared with control group,the release of silver ions of CSNG was much slower.Sterilization experiment showed that CSNG killed the MRSA,Escherichia coli and Candida albicans much more efficiently,compared to that in the other treatments.Animal experiments also showed that CSNG promoted the rats of wound healing.Conclusion·Combining chitosan with silver nitrate and supplementary material could develop a novel chitosan-silver nitrate gel material,which not only has the obvious effects on antibacterial,but also on promoting wound healing.

Objective·To investigate effect and the possible molecular mechanism of JQ1,a specific inhibitor of bromodomain containing protein 4,on human hypertropic scar.Methods·Primary fibroblasts were isolated from human hypertrophic scars and treated with JQ-1 of different concentrations (0.1,0.5,1.0,2.0,2.5,and 12.5μmol/L) for 48 h.Then CCK-8 kit and wound healing assay were used to measure proliferation and migration of the fibroblasts.ELISA was adopted to detect the levels of collagen type Ⅰ (COL Ⅰ) and TGF-β1 after JQ-1 treatment for 24 h.Thirty-six nude mice were used for hypertrophic scar models.Human hypertrophic scars (1.0 cm× 1.0 cm×0.5 cm) were grafted subcutaneously at the backs of nude mice to establish scar animal models.After 4 weeks,the nude mice were averagely divided into two groups,i.e.JQ-1 group and DMSO group,which were respectively injected with 0.5 μmol/L JQ-1 and 0.1％ DMSO each mouse every day.COL Ⅰ / Ⅲ and α-smooth muscle actin (α-SMA) were examined by immunohistochemical method and sirius red staining.Results·Cell experiments showed that JQ-1 with the concentration of 0.5 μmol/L and above significantly inhibited proliferation of fibroblasts (P＜0.01).JQ-1 inhibited migration of fibroblast (P＜0.01).JQ-1 inhibited secretion of COL Ⅰ and TGF-β1 of fibroblasts (P＜0.01).Animal experiments showed that concentration and proportion of COL Ⅰ / Ⅲ in JQ-1 group decreased compared to DMSO group (P＜0.05).α-SMA protein expression in JQ-1 group also decreased (P＜0.05).Conclusion·JQ-1 can inhibit proliferation,migration,secretion of COL Ⅰ,and production of TGF-β1 of human sear fibroblasts in vitro;it can also inhibit secretion of COL Ⅰ /Ⅲ and fibroblast-myofibroblast differentiation in the human hypertrophic scars in nude mice.

Objective:To see the influence of different antiplatelet therapies on stroke patients’ readmission by performing a deep data-mining into Beijing Healthcare Insuring Database,based on a large sample size.Methods:Aretrospective cohort study,was adopted to extract patients primarily diag-nosed as ischemic stroke from healthcare database.The first hospital records were considered as the pa-tient’s baseline in this study,who were divided into MAPT (aspirin)and DAPT (aspirin and clopi-dogrel)according to the patient’s baseline medications.A follow-up was conducted to see whether the patients would have rehospitalization record because of major result events after medication.The major re-sult events,included:(1 )recurrence of ischemic stroke;(2)hemorrhagic transformation of ischemic stroke;(3)myocardial infarction;(4)the digestive hemorrhage.The Kaplan-Meier figure was used to compare the survival situations between these two groups,the log-rank test was used to test the difference of the survival curve,and 1 ∶1 propensity score matching was calculated from the patients’baseline da-ta.Cox proportional hazards model was used to calculate the hazard ratio (HR).Results:A total of 27 695 patients From January 201 0 to September 201 3 were included,4 047 with DAPT,and 23 648 with MAPT.Because the baseline characteristics of the patients was disequilibrium,so we used 1 ∶1 pro-pensity score matching,after which,the number of the two groups was 4 046 each.Adjusted for the gen-eral demographic characteristics such as age,sex,nationality,complication and drug combination,no statistical significance was observed between the survival curves of the two groups (P =0.06).HR value of major result events between the groups was 0.91 (0.82 -1 .01 ,P =0.07),which was not statistically significant.The covariate gender HR =1 .36 (1 .20 -1 .55,P <0.05),accompanied by diabetes HR =1 .36 (1 .20 -1 .54,P <0.05 ),dyslipidemia HR =1 .1 3 (1 .00 -1 .27,P =1 .1 3),heart disease HR =1 .39 (1 .22 -1 .58,P <0.05)was statistically significant.Drug combination with other antiplate-let agents HR =1 .05 (0.95 -1 .1 7,P >1 .05)did not increase the risk of readmission.Conclusion:There was no difference in prevention of readmission between patients with DAPT and MAPT.Patients with complications should actively treat the complications at the same time as they prevent recurrence after first attack.

Objective:To explore the influencing factors of health information-seeking behavior in stroke patients and analyze its influencing path.Methods:A total of 280 stroke patients in Xuzhou Municipal Hospital Affiliated to Xuzhou Medical University from February to July 2022 were selected as research objects by convenience sampling method. General Data Questionnaire, Stroke Self-Efficacy Scale, Medical Social Support Scale, Electronic Health Literacy Scale and Health Information-Seeking Behavior Questionnaire were used to investigate patients. Multiple linear regression analysis was used to investigate the influencing factors of health information seeking behavior in stroke patients. Amos 26.0 was used to establish the structural equation model and analyze the path. A total of 280 questionnaires were distributed in this study, and 268 were effectively collected, with an effective recovery rate of 95.71% (268/280) .Results:The score of health information-seeking behavior in stroke patients was (108.53±28.34). Multiple linear regression analysis showed that education, residence, number of hospitalizations due to stroke, self-efficacy and social support were the influencing factors of health information searching behavior of stroke patients ( P<0.05), which could explain 88.3% of the total variation. The structural equation model results showed that self-efficacy of stroke patients had a complete mediating effect between social support and health information searching behavior, and the indirect effect accounted for 80.29% of the total effect. Conclusions:The health information-seeking behavior of stroke patients is at a moderate level. Medical staff should formulate targeted intervention measures according to its influencing factors, and give full play to the mediating role of self-efficacy between social support and patients' health information-seeking behavior.

OBJECTIVE: To investigate the effect of down-regulation of pannexin 2 (Panx-2) channels on cisplatin-induced apoptosis in I-10 cells. METHODS: The expression of Panx-2 protein in testicular cancer cells was detected with Western blotting. The testicular cancer cell line I-10 was transfected with two short hairpin RNA (shRNA1 and shRNA2) Lipofectamine, the empty vector (NC group) or Lipofectamine2000 (blank control group), and the changes in the expression of Panx-2 was detected with Western blotting. The effects of transfection with a Panx-2 inhibitor on surviving fraction of the cells treated with cisplatin (16 μmol/L) for 24 h, 48 h and 72 h was assessed with MTT assay, and the clonogenic capacity of the cells was evaluated with colony-forming assay. At 8 h after incubation with 16 μmol/L cisplatin, AnnexinV/PI double staining was used to detect the early apoptosis of the cells. After 24 h of treatment with 16 μmol/L cisplatin, the cells were examined for expressions of caspase-3, Bcl-2 and Bax using Western blotting. RESULTS: The expression of Panx-2 was significantly increased in cisplatin-resistant I-10/DDP ( < 0.001) cells and Tcam-2/DDP ( < 0.01) cells as compared with I-10 cells and Tcam-2 cells. Transfection of I-10 cells with shRNA1 and shRNA2 resulted in significantly decreased Panx-2 expression ( < 0.05) and significantly reduced cell surviving fraction ( < 0.001). In the presence of cisplatin, the cells in NC group showed a higher clonogenic efficiency than those in shRNA1 and shRNA2 groups ( < 0.001). The early-stage apoptosis rate of the cells in shRNA1 and shRNA2 groups were significantly higher than that in NC group ( < 0.01). Panx-2 knockdown in I-10 cells significantly increased caspase-3 and Bax expressions ( < 0.05) and significantly decreased the expression of Bcl-2 ( < 0.01). CONCLUSIONS Down-regulation of Panx-2 channel enhances cisplatin-induced apoptosis in cultured testicular cancer cells.

Atherosclerosis is a complex pathological condition resulting from lipid deposition， chronic inflammatory responses， and fibrosis， with a prolonged disease course and multifactorial etiology. Based on the traditional Chinese medicine （TCM） theory of accumulation syndrome， atherosclerosis can be classified under this category， with its pathogenesis involving phlegm， blood stasis， deficiency， and accumulation. This paper proposed a stage-based intervention strategy using the four therapeutic principles of "attacking， supplementing， dispersing， dissipating"， and divided into six stages based on the pathological progression， including the stage of accumulation before formation， the stage of accumulation already formed， the stage of nucleus accumulation， the stage of nucleus accumulation decay， the stage of nucleus accumulation consolidation， and the stage of severe stenosis of nucleus. At different stages， the intervention focuses on reinforcing healthy qi and consolidating the root， tonifying the kidneys and spleen， dispersing and removing turbidity， removing phlegm stagnation， promoting qi circulation， dispersing accumulations and removing stasis， attacking accumulation and expelling stasis， directing the turbid downward and dispersing accumulation， and treatment would be adjusted based on specific symptoms， which provides a theoretical framework for the prevention and treatment of atherosclerosis with TCM.

Objective:Factors influencing the prognosis of hemophagocytic lymphohistiocytosis (HLH) in adults were analyzed based on multicentric data.Methods:Clinical data of 124 adult patients with HLH diagnosed in eight medical centers in the Huaihai Lymphoma Working Group from March 2014 to July 2020 were collected. The optimal truncation value of continuous variables was obtained based on the Maxstat algorithm, X-Tile software, and restricted cubic spline. Cox proportional risk regression model was used to construct the adult HLH risk prediction model, and the visualization of the model was realized through the histogram. The bootstrap resampling method was used to verify the model, C-index and calibration curve was used to verify the histogram, and the prediction accuracy was checked. Kaplan-Meier analysis was used to calculate the survival rate and draw the survival curve. Furthermore, the differences between groups were tested by log-rank.Results:The median age of the 124 patients was 55 (18-84) years, including 61 (49.19%) males. The most common etiology was infection. Serum ferritin increased in 110 cases (88.71%) , hepatosplenomegaly in 57 cases (45.97%) . Of the 124 patients, 77 (62.10%) died, and the median survival time of the patients was 7.07 months. Univariate results showed that the prognosis of adult HLH was influenced by sex, age, fibrinogen, serum creatinine, alanine aminotransferase, and albumin ( P<0.05) . The results of multivariate analysis showed that gender, platelet, albumin, alanine aminotransferase, and treatment regimens were independent influencing factors for prognosis. Based on the above five risk factors, the prediction model of the histogram was established, and the C-index of the model was 0.739. Finally, the calibration chart showed good consistency between the observed and predicted values of HLH. Conclusion:The prognosis of the adult hemophagocytic syndrome is influenced by many factors. Gender, platelet, albumin, alanine aminotransferase, and treatment regimens are independent risk factors. Therefore, the established histogram provides a visual tool for clinicians to evaluate the prognosis of adult HLH.
