[Objective] To investigate professor SHAN Zhaowei's experience of diagnosing and treating bile reflux gastritis(BRG). [Method] The experience of Professor SHAN Zhaowei on recognition of etiology and pathogenesis, treatment principle, characteristics of prescription selection and administration of BRG is summarized and studied. Besides his academic ideas and clinical medication experience are shown with typical cases. [Result] In his view, emotional disorder is the most common etiology, and liver-stomach disharmony is the basic pathogenesis. He puts forward that we should pay attention to dispersing the stagnated liver Qi, regulating the stomach to lower the adverse flow of Qi when we treat it, and emphasizes the combination of disease differentiation and syndrome differentiation. Meanwhile, herbs of protecting gastric mucosa are compatibly used to improve the curative effect. And the case in this article has obtained good treatment results. [Conclusion] Pro. SHAN Zhaowei thinks that emotional regulation to patency for patients is very important. The dispersing the stagnated liver Qi, regulating the stomach and protecting gastric mucosa treatment proposed by SHAN Zhaowei is smart, simple and effective, which embodies the characteristic of his healing and MengHe Medicine.

Objective To design and test a device which is capable of accurately measuring and dynamically adjusting the axial pressure at the fracture end in real-time.Methods Upon completion of the design,the pressure measurement and adjustment device was implemented in a canine tibial fracture external fixation model.A pressure sensor was mounted at the fracture end,and the displayed values of the pressure sensor were used as the standard for comparison.The relationship between the displayed values of the measurement and adjustment device and the pressure sensor under identical conditions was examined.Results The device was utilized in external fixation models of tibial fractures in five beagles.A linear correlation was observed between the displayed values of the device and the pressure sensor at the fracture end.The measurement values from the device could be transformed into fracture end pressure through the application of coefficients,thereby facilitating accurate measurement and dynamic adjustment of the fracture end pressure.Conclusion The pressure measurement and adjustment device at the fracture end is easy to operate,enabling precise measurement and dynamic regulation of the pressure at the fracture end.It is well-suited for animal experiments aimed at investigating the impact of axial compression on fracture healing,demonstrating promising potential for experimental applications.

Objective:To explore the effect of sulforaphane (SFN) preconditioning on the cold myocardial ischemia-reperfusion injury (IRI) in the rats through PI3K/Akt signaling pathway.Methods:Sixty-four health male Sprague-Dawley (SD) rats were randomly divided into cold IRI group,SFN group,LY (LY294002) + cold IRI group,and LY+SFN group (n=16).The allogeneic heterotopic heart transplantation model was established by donor heart into recipient abdomen.The myocardium tissue was taken 24 h after reperfusion for the detection of histological changes using HE staining.The expression levels of Akt,p-Akt,Bax and Bcl-2 proteins were detected by immunohistochemistry and Western boltting methods.Results:The morphological results showed that the myocardium tissue damage was serious in cold IRI group and LY+cold IRI group,it was light in SFN group;the myocardium tissue damage of the rats in SFN+ LY group was ranged between cold IRI group and SFN group.Compared with IRI group,the expression levels of p-Akt protein and Bcl-2 protein in SFN group were increased (P<0.05),and the expression level of Bax protein was decreased (P<0.05).After treatment of blockage LY294002,compared with LY-+-cold IRI group,the expression level of p-Akt protein in LY-+-SFN group was not statistically significant (P>0.05),the expression level of Bcl2 protein was increased (P<0.05),the expression levels of Bax protein was decreased),and the ratio of Bcl-2/Bax was also increased (P<0.05).Conclusion:SFN may attenuate cold IRI of heart transplantation through PI3K/Akt signaling pathway in the rats.

Background::Hypothermia therapy has been suggested to attenuate myocardial necrosis; however, the clinical implementation as a valid therapeutic strategy has failed, and new approaches are needed to translate into clinical applications. This study aimed to assess the feasibility, safety, and efficacy of a novel selective intracoronary hypothermia (SICH) device in mitigating myocardial reperfusion injury.Methods::This study comprised two phases. The first phase of the SICH was performed in a normal porcine model for 30 minutes ( n = 5) to evaluate its feasibility. The second phase was conducted in a porcine myocardial infarction (MI) model of myocardial ischemia/reperfusion which was performed by balloon occlusion of the left anterior descending coronary artery for 60 minutes and maintained for 42 days. Pigs in the hypothermia group ( n = 8) received hypothermia intervention onset reperfusion for 30 minutes and controls ( n = 8) received no intervention. All animals were followed for 42 days. Cardiac magnetic resonance analysis (five and 42 days post-MI) and a series of biomarkers/histological studies were performed. Results::The average time to lower temperatures to a steady state was 4.8 ± 0.8 s. SICH had no impact on blood pressure or heart rate and was safely performed without complications by using a 3.9 F catheter. Interleukin-6 (IL-6), tumor necrosis factor-α, C-reactive protein (CRP), and brain natriuretic peptide (BNP) were lower at 60 min post perfusion in pigs that underwent SICH as compared with the control group. On day 5 post MI/R, edema, intramyocardial hemorrhage, and microvascular obstruction were reduced in the hypothermia group. On day 42 post MI/R, the infarct size, IL-6, CRP, BNP, and matrix metalloproteinase-9 were reduced, and the ejection fraction was improved in pigs that underwent SICH.Conclusions::The SICH device safely and effectively reduced the infarct size and improved heart function in a pig model of MI/R. These beneficial effects indicate the clinical potential of SICH for treatment of myocardial reperfusion injury.
