AIM:To investigate the potential of differentiatng into myocytes of the granulocyte colony-stimulating factor(G-CSF)-mobilized CD34 + cells. METHODS: Three hours after intraperitoneal injecction of isoprenaline(ISO) to develop acute ischemic model, rats' bone marrow hematopoietic stem cells were mobilized to the site of myocardial infarction by G-CSF. The techniques of immunohistochemisty and HE stain were used to detect the infiltration of CD34 + cells and the regeneration of myocytes in the infarct zones. RESULTS: 24 hours after administration of ISO , a large amount of infiltrative monocytes and regenerative myocytes which were CD34 positive expression could be found in the infarct zones of the G-CSF treatment group, while majority of the infiltrative inflammatory cells in control group were neutrophils and there was no infiltrative cells and myocytes which were CD34 positive expressio, 2 weeks after administration of ISO, there were a plenty of scar in control group, but not in the G-CSF treatment group. CONCLUSION: G-CSF-mobilized CD34 + cells possess the potential to differentiate into myocytes and it may be used in treating acute myocardial infarction.

AIM: To investigate the effects of granulocyte colony-stimulating factor (G-CSF)-mobilized bone marrow stem cells on treatment of the myocardial infarction in experimental rats. METHODS: Three hours after injected with isoprenaline(ISO) interaperitoneally to develop acute ischemic model, rats' bone marrow stem cells were mobilized by G-CSF and migrated to the site of myocardial infarction. The hearts were harvested from 24 hours to 2 weeks after administration of ISO for histopathological examination. RESULTS: 24 hours after administration of ISO , myocardial infarct zones scattered in the pallium of the control group ,there were a large amoumt of inflammatory cells infiltration around the infarct zones and majority of them were neutrophils. The infarction in the G-CSF treatment group was milder, majority of the infiltrative cells were monocytoid; 48 hours after administration of ISO, infarct zones expanded greatly in control group, while that of the G-CSF treatment group increased just mildly; 2 weeks after administration of ISO, there was no significant scar in the G-CSF treatment group. We also found the regeneration of myocytes in the pallium. CONCLUSION: G-CSF treatment protected the ischemic myocardium and it may be used to treat the acute myocardial infarction.

Objective:To evaluate the effect of psychological intervention on postoperative outcomes of adolescent idiopathic scoliosis (AIS) patients undergoing correction.Methods:A computer-based online search of PubMed, Embase, Cochrane Library, Web of Science, CINAHL, MEDLINE, PsycINFO, PQDT, China National Knowledge Infrastructure (CNKI) , Wanfang Database, VIP Chinese Journal Database, China Biology Medicine disc, controlled-trials and chictr clinical controlled trial databases from establishment to July 25, 2021 was performed for randomized controlled trials (RCTs) on the effect of psychological intervention on adolescent AIS patients undergoing correction surgery. RevMan 5.3 statistical software was used for meta-analysis.Results:Finally, 10 articles were included, with a total of 621 patients. Meta-analysis showed that psychological intervention could reduce postoperative pain ( SMD=-0.62, 95% CI: -1.15- -0.08, P=0.02) and reduce postoperative anxiety ( SMD=-0.54, 95% CI: -1.03- -0.06, P=0.03) , descriptive analysis showed that cognitive behavioral therapy could improve postoperative quality of life and mobility. Conclusions:Psychological intervention can reduce the pain and anxiety level of patients with scoliosis after surgery, improve the quality of life after surgery and improve the activity ability. However, due to the small number of studies and high heterogeneity of results, higher quality and large sample studies are needed to further validate the intervention effect and provide guidance for clinical practice.

Objective:To construct a prognostic model for severe acute pancreatitis (SAP) based on CT scores and inflammatory factors, and to evaluate its efficacy.Methods:128 patients with SAP diagnosed admitted to the First Hospital Affiliated to Hebei North College from March 2019 to December 2021 were enrolled and given Ulinastatin combined with continuous blood purification therapy. The levels of C-reactive protein (CRP), procalcitonin (PCT), interleukins (IL-6, IL-8), tumor necrosis factor-α (TNF-α), and D-dimer were measured before and on the third day of treatment. An abdominal CT was performed on the third day of treatment to assess the modified CT severity index (MCTSI) and extra-pancreatic inflammatory CT score (EPIC). Patients were divided into the survival group ( n = 94) and the death group ( n = 34) according to the 28-day survival prognosis after admission. The risk factors for the SAP prognosis were analyzed using Logistic regression, which was then used to build nomogram regression models. The value of the model was evaluated using the concordance index (C-index), calibration curves and decision curve analysis (DCA). Results:Before treatment, the levels of CRP, PCT, IL-6, IL-8 and D-dimer in the death group were higher than those in the survival group. After treatment, the levels of IL-6, IL-8 and TNF-α in the death group were higher than those in the survival group. MCTSI and EPIC scores in the survival group were lower than those in the death group. Logistic regression analysis shows that, pre-treatment CRP > 140.70 mg/L, D-dimer > 2.00 mg/L, and post-treatment IL-6 > 31.28 ng/L, IL-8 > 31.04 ng/L, TNF-α > 31.04 ng/L, and MCTSI > 8 points were all independent risk factors for SAP prognosis [odds ratios ( OR) and 95% confidence intervals (95% CI) were 8.939 (1.792-44.575), 6.369 (1.368-29.640), 8.546 (1.664-43.896), 5.239 (1.108-24.769), 4.808 (1.126-20.525), 18.569 (3.931-87.725), all P < 0.05]. Model 1 (consisting of pre-treatment CRP, D-dimer, and post-treatment IL-6, IL-8 and TNF-α) had a lower C-index than that model 2 (consisting of pre-treatment CRP, D-dimer, and post-treatment IL-6, IL-8 and TNF-α, and MCTSI; 0.988 vs. 0.995). The mean absolute error (MAE) and mean square error (MSE) of model 1 (0.034, 0.003) were higher than those of model 2 (0.017, 0.001). When the threshold probability was in the range of 0-0.66 or 0.72-1.00, the net benefit of model 1 was lower than that of model 2. When the threshold probability was in the range of 0.66-0.72, the net benefit of model 1 was higher than that of model 2. In addition, model 2 had a higher C-index than acute physiology and chronic health evaluationⅡ (APACHE Ⅱ) and bedside index of acute pancreatitis severity (BISAP, 0.995 vs. 0.833, 0.751). Model 2 had a lower MAE (0.017) and MSE (0.001) than APACHEⅡ (0.041, 0.002). Model 2 had a lower MAE than BISAP (0.025). Model 2 had a higher net benefit than both APACHEⅡ and BISAP. Conclusion:The prognostic assessment model of SAP consisting of pre-treatment CRP, D-dimer, and post-treatment IL-6, IL-8 and TNF-α, and MCTSI has high discrimination, precision and clinical application value, and is superior to APACHEⅡ and BISAP.
