Objective To explore the effects of health education based on the transtheoretical model (TTM) on intestinal preparation quality and psychological stress of patients undergoing endoscopic treatment. Methods A total of 134 patients treated with digestive endoscopy in the Second People's Hospital Zhengzhou from February 2021 to October 2022 were selected and divided into the observation group(n=67) and the control group(n=67) according to the random number table method. The control group received routine nursing intervention, and the observation group received health education intervention based on TTM. The quality of intestinal readiness [Boston Bowel Preparation Scale(BBPS), Ottawa Bowel Preparation Scale (OBPS)], psychological stress [Connor-Davidson resilience scale(CD-RISC)],complications(nausea. choking, abdominal pain, bloating), quality of life [Activity of Daily Living Scale(ADL)] and nursing satisfaction of the two groups were statistically compared. Results After intervention, BBPS, CD-RISC and ADL scores in the observation group were higher than those in the control group, and the OBPS scores were lower than those in the control group, and the differences were statistically significant (P<0.05). After the intervention, the incidence of complications in the observation group was 1.49%, lower than that in the control group(11.94%), and the difference was statistically significant(P<0.05). After intervention, the satisfaction of the observation group was 100.00%, higher than that of the control group (88.06%), the difference was statistically significant(P<0.05). Conclusion Health education based on TTM can regulate the psychological stress of patients undergoing endoscopic treatment, improve the quality of intestinal preparation, reduce complications. improve the quality of life, and enhance nursing satisfaction.

Objective: To study the methods of primary culture and purity identification of bone marrow mesenchymal stem cells. Methods: In a sterile environment, the bone marrow was collected from the femur and tibia of SD rats, digested with enzymes first, and subcultured the extracted BMSCs by using the whole bone marrow cell suspension adherence method, and the third generation cells with good growth were selected for identification; BMSCs were induced to differentiate into adipogenic and osteogenic, and the differentiation effect of BMSCs was identified by oil red O (ORO) and alizarin red (ARS) staining; CD34, CD44 and CD90 were detected by flow cytometry (FCM). The expression of three types of BMSCs surface markers was analyzed. Results: BMSCs are long spindle-shaped adherent cells, and the growth state is fibroblast-like swirl. During the passage of the third generation BMSCs, they developed to the growth latent period on the 1st-3d, showing a slower growth rate, and developed on the 3rd-5d. In the logarithmic growth phase, it grows at a high speed. After the 7th day, the growth speed reaches the maximum, and the speed stops increasing and enters the plateau phase. After the induction of osteogenesis and adipogenicity of BMSCs, the identification of the induced differentiation found that the cells showed obvious morphological changes, Staining fat by ORO, the cells showed orange red; after the end of osteogenic induction culture, staining calcium salt by ARS showed red, and mineralized nodules appeared, indicating that BMSCs had good osteogenic and adipogenic differentiation capabilities; FCM It was found that the expression of CD34 was negative (1.09 %), and both CD90 (96.8 %) and CD44 (92.4 %) were positive, which was consistent with the phenotype of BMSCs. Conclusion: BMSCs were effectively isolated and cultured by the whole bone marrow adherent culture technique. [ABSTRACT FROM AUTHOR]

Objective To investigate the effect and mechanism of celastrol on lipopolysaccharide（LPS）-induced acute lung injury（ALI）in septic rats. Methods Eighteen male SD rats were randomly divided into the control group， model group，and celastrol group with 6 rats in each group. The rats in the model group were injected with 5 mg/kg LPS through tail vein to establish ALI models. The rats in the celastrol group were injected with the same amount of LPS through tail vein and 1 mg/kg of 0. 02% celastrol intraperitoneally. The rats in the control group were separately injected with the same amount of normal saline through tail vein and abdominal cavity. After 24-hour culture，the abdominal aorta blood was collected，and PO2 of the abdominal aorta was detected by blood gas analyzer. Rats were executed with narcotic overdose，and the chests in the rats were dissected under aseptic conditions. The left lung tissues were taken，and the wet weight was weighed. After drying in the oven，the dry weight of rats was weighed，and the ratio of the wet weight to the dry weight of the lung tissues（W/D）was calculated. The inferior lobe of right lung in rats was taken and HE staining was per⁃ formed to observe the pathological changes in the lung tissues under light microscope，and pathological score of lung injury was performed. The middle and superior lobes of right lung in the rats were homogenized in ice bath，and the supernatant was extracted by centrifugation. The content of TNF-α，IL-1β，intercellular adhesion molecule-1（ICAM-1），and vascular cell adhesion molecule-1（VCAM-1）in the lung tissues was determined by ELISA. The inferior lobe of right lung was tak⁃ en and fully lysed with RIPA lysate. Cytoplasmic protein and nuclear protein were extracted according to the instructions of cytoplasmic nucleoprotein extraction kit. The content of NF-κB in the cytoplasm and nucleus was determined by ELISA. Results Compared with the control group，PO2 of abdominal aorta and cytoplasmic NF-κB in the lung tissues significant⁃ ly decreased in the model group and celastrol group，while the W/D ，the content of TNF-α，IL-1β，ICAM-1，and VCAM-1 in the lung tissues and NF-κB in nucleus，and pathological score of lung injury significantly increased（all P<0. 05）. Com⁃ pared with the model group，PO2 of the abdominal aorta，NF-κB in cytoplasm of the lung tissues significantly increased in the celastrol group，while the W/D，the content of TNF-α，IL-1β，ICAM-1，and VCAM-1 in the lung tissues and NF-κB in nucleus，and pathological score of lung injury significantly decreased（all P<0. 05）. Compared with the control group， the alveolar hyperemia and bleeding were obvious in the model group，accompanied by a large number of inflammatory cell infiltration，and the alveolar structure collapsed and the contour was not clear. However，compared with the model group， the alveolar hyperemia and bleeding were significantly reduced in the celastrol group，and a small amount of inflammatory cell infiltration was observed in the alveolar，and the alveolar structure was clearly visible. Conclusion Celastrol can inhibit LPS-induced ALI in sepsis rats，and the mechanism may be related to the inhibition of nuclear translocation of NF-κB，thus inhibiting the content of inflammatory cytokines in rats.

There are too many creep models at present,but none has summarised these models' applicability,advantages and disadvantages yet.Also,the relation between coal rock creep and low gas pressure is unclear.Therefore,the creep test of coal rock under different gas pressures at triaxial stress was carried out to study the influence of gas on creep,and the applicability of various common creep models.The results show that the larger the gas pressure is,the greater the axial strain of coal and rock.The coal creep is positively correlated with the gas pressure.Then,the experimental data were used to test these common creep models.It was found that the empirical equations,such as the power function,exponential function and polynomial function,can only fit one of the decay or non-decaying creep.The Nishihara model cannot fit the non-decaying creep,and the Burgers model and its improved model has a few defects in fitting the decay and non-decaying creep curves.The Nishihara acceleration model has hysteresis,when it is used to fit the non-decaying creep of coal rock.And the Nishihara acceleration model is suitable for sandstone creep but not for coal rock creep.In this paper,the Nishihara acceleration model was improved.It is concluded that the improved Nishihara acceleration model can better describe the creep of coal rock.In addition,the theory of creep inflection point was presented.The creep curve at least has one creep inflection point,which is the necessary and sufficient condition for the non-decaying creep of rock.It not only enhances the theory of acceleration creep,but also has some guiding significance to prevent rock steady failure and other engineering practices.
