BACKGROUND:Several studies have demonstrated that many kinds of Chinese herbs for benefiting vital energy and enriching the blood secrete some cytokines by influencing bone marrow stromal cel s to promote the differentiation and proliferation of hemopoietic stem cel s or exert effects by promoting the adhesion of bone marrow stromal cel s and hemopoietic stem cel s.
OBJECTIVE:To investigate the effects of Radix Astragali injection on the expression of intercel ular adhesion molecule 1 and vascular cel adhesion molecule 1 on the surface of mouse bone marrow stromal cel s.
METHODS:Mouse bone marrow stromal cel s were isolated by adherent culture of whole bone marrow. The morphology of mouse bone marrow stromal cel s were observed using inverted phase microscopy, hematoxylin-eosin staining, optical microscopy and transmission electron microscopy. The optimal concentration at which Radix Astragali injection exhibited the strongest effects on promoting the proliferation of bone marrow stromal cel s was detected using MTT assay. Expression of intercel ular adhesion molecule 1 and vascular cel adhesion molecule 1 on the surface of mouse bone marrow stromal cel s was detected using flow cytrometry after intervention by Radix Astragali injection.
RESULTS AND CONCLUSION:Inverted phase microscopy and optical microscopy showed that bone marrow stromal cel s adhered to the wal of culture flask, exhibited a shuttle-shaped or irregular appearance with processes. Through transmission electron microscopy, organel es were abundant, such as rough endoplasmic reticulum, secretory vesicle, and mitochondria. Radix Astragali injection at 400 and 600 mg/L significantly promoted the proliferation of mouse bone marrow stromal cel s (P<0.05) and there was no significant difference in the cel proliferation between these two concentrations. Radix Astragali injection at 600 mg/L increased the expression of intercel ular adhesion molecule 1 and vascular cel adhesion molecule 1 on the surface of mouse bone marrow stromal cel s. These findings suggest that Radix Astragali injection at appropriate concentrations can increase the surface adhesion of bone marrow stromal cel s, thereby improving hemopoietic microenvironment.

Objective To design a kind of special support mattress for the endoscopic retrograde cholangiopancreatography (ERCP), and to improve the comfort of the patients during the procedure, and evaluate the efficacy and safety during clinical application. Methods By 3D modeling, we designed a special memory foam mattress for ERCP. From January 2014 to September 2014, 424 patients who underwent ERCP treatment without general anesthesia and could take semi-prone position, were divided into special mattress group (210 cases) and ordinary mattress group (214 cases) according to the random number table method. The satisfaction of the patients and the operators of the two groups were evaluated and compared. Results The operation times of the two groups were (32.9±18.5) min and (33.2±20.1) min, respectively, and there was no significant difference between the two groups (P>0.05). The overall satisfaction ratings of the patients in the two groups were (7.9±1.6) points and (6.3±1.3) points, respectively (P<0.01), and the discomfort ratings of the patients in the two groups were (1.3± 0.9) points and (3.8 ±1.2) points (t=116.45, 246.91, P<0.01). The operator satisfaction scores of two groups were (8.5±1.3) points and (8.5±1.8) points, respectively, and there was no significant difference (P>0.05). No mattress related complications were found. Conclusions The special memory foam mattress for ERCP can alleviate the discomfort and improve the tolerance during the procedure. Therefore, it is worth promoting the application.

Objective Many studies have suggested that cardiovascular risk factors seem to be more common in psoriasis patients than in general population.In this study we aimed to investigate the prevention and treatment of cardiovascular risk in psoriasis patients by Framingham cardiovascular risk assessment in patients with psoriasis vulgaris and normal people using Framingham score.Methods We conducted a prospective study including 90 outpatients with psoriasis vulgaris and 137 controls without psoriasis from October 2015 to October 2016 in our hospital.All psoriasis patients were diagnosed clinically and histopathologically.The severity of psoriasis was assessed according to the psoriasis area and severity index (PASI) score.Along with a thorough medical history and physical examination, serum lipid profile, blood pressure and fasting plasma glucose tests were carried out.The 10-year Framingham risk score (FRS) for general cardiovascular disease included indexes concerning age, gender, total cholesterol, HDL-cholesterol, systolic blood pressure and smoking history.Results We found the 10-year FRS was significantly higher in patients with psoriasis vulgaris than in controls (P<0.05).The 10-year FRS was in positive relation with gender(r=0.358), age(r=0.678) and course of disease(r=0.257).No relation has been found in 10-year FRS and psoriasis features(r=0.184, P>0.05).No significance was found in the 10-year FRS of patients with mild and severe psoriasis (P>0.05).FRS was significantly higher in male patients and in patients above 50 years old (P<0.05).Conclusion Psoriasis patients, especially the older male patients, tend to have high risks of cardiovascular disease.Therefore, risk assessment for cardiovascular diseases should be conducted in psoriasis patients, and complications should be actively prevented and treated.
