Conclusion:The HD mobile video visit system is a new effective choice for hospital's NICU visit systems, and it will be good clinical significance.

Objective: To investigate the relationship between anemia and severity of coronary artery lesions.Methods: A total of 227 consecutive patients with coronary artery disease(CAD) were studied.According to their hemoglobin levels,all patients identified positive by selective coronary angiography(CAG) were divided into two groups,anemic group and non-anemic group,their clinical types and severity of coronary artery lesions were compared.Results: The proportion of anemia in unstable angina and infarction group was higher than those in stable angina group,similarly the proportion of anemia was also high in severe stenosis,occlusion and three-branch stenosis groups than that in other groups.Conclusion: Anemia is possibly one of the predictive factors suggesting CAD's clinical types and deterioration of coronary artery stenosis.

Objective To explore the role of serum levels of Klotho protein and fibroblast growth factor(FGF)-23 in patients with chronic kidney disease(CKD).Methods A total of 160 patients with CKD were recruited into CKD group in this study,160 healthy controls were selected in the control group from March 2014 to March 2016.Basic clinical data,blood biochemical index,serum level of Klotho protein and FGF-23 were analyzed and compared between the two groups.Results The hemoglobin,serum albumin,blood calcium,glomerular filtration rate,Klotho protein levels in the CKD group were lower than those in the control group,and the serum creatinine,blood urea,blood serum phosphorus and FGF-23 were higher than those in the control group(P<0.05).With the progress of CKD stages,hemoglobin,glomerular filtration rate,Klotho protein levels gradually decreased,serum creatinine,blood urea,blood serum phosphorus,FGF-23 level increased(P<0.05).The levels of FGF-23 were negatively related to hemoglobin,glomerular filtration rate,Klotho(r=-0.584,0.692,-0.724)and were positively correlated to serum creatinine,blood urea,blood serum phosphorus(r=0.814,0.703,0.527).The levels of Klotho protein were positively related to hemoglobin,glomerular filtration rate(r=0.612,0.685),and were negatively correlated to serum creatinine,blood serum phosphorus,blood urea,FGF-23(r=-0.720,-0.690,-0.519,0.724).Conclusion High concentrations of FGF-23 and Klotho protein with low concentration were not only related to calcium phosphate metabolic disorders of patients with CKD,and were also associated with the prognosis of patients with CKD,which might be early biomarkers and predictor in patients with CKD.

Objective: Various quantitative assessments of coronary heart disease(CHD) risk factors was performed to evaluate severity and predicting its occurrence rate.Methods:282 cases,were selected to be scored by Framingham,PROCAM(The Prospective Cardiovascular Munster Study) and Chinese risk scores respectively.We compared the relationship between three risk scores and severity,extent of coronary artery through correlation analysis,and subsequently analyzed their predictive value.Results: Chinese risk score,PROCAM risk score,Framingham risk score were significantly correlated with extent and severity of coronary artery atherosclerosis(CAAS),with PROCAM risk score,the highest correlation of it and Framingham risk score,the smallest.Risk scores increased with coronary artery pathological change advancing.The areas under resident operation character(ROC) of Framingham risk score was the least,whereas that of PROCAM was the largest.Conclusion: Among the three risk scores described above used to evaluate the severity of CAAS and predict incidence of CHD,PROCAM risk scores was the superior.

Objective To compare the influences of different routes of nutrition on the outcome and respiratory muscle strength of elderly patients in respiratory intensive care unit (RICU). Methods Totally 147 elderly patients in RICU were equally randomized into combined nutrition group ( combinination of parenteral nutrition and enteral nutrition), total enteral nutrition (EN) group, and total parenteral nutrition (PN) group. The changes of energy metabolism, respiratory muscle strength, and short-term outcome were observed or determined.Results Plasma albumin (ALB), hemoglobin (Hb), creatinine (Cr) levels, and nitrogen balance significantly increased in all group 7 days later ( all P ＜ 0. 01 ), while blood urea nitrogen (BUN) significantly decreased ( P ＜0.01 ). The increase of ALB, Hb, Cr levels, and nitrogen balance were significantly more remarkable than that in EN group and PN group (P＜0.05 or P＜0.01). The decrease of BUN level in the combined nutrition group was significantly more remarkable than that in EN group ( P ＜ 0. 05 ). After nutritional support, the maximum inspiratory pressure in the combined nutrition group (P =0. 021 ) and EN group (P = 0. 011 ) became significantly higher, and occlusion pressure at 0.1 second inspiration level in the combined nutrition group became significantly lower ( P =0. 025). The incidences of infectious and non-infectious complications in PN group were significantly higher than those in EN group (P = 0. 002 and 0. 017, respectively) and combined nutrition group ( P = 0. 005 and 0. 004, respectively). Gastric retention was more common in EN group than that in PN group ( P = 0. 035). The weaning time,length of RICU stay, length of hospital stay and 20-day-mortality were significantly decreased in the combined nutrition group than those in the other two groups ( all P ＜ 0. 05 ). Conclusion The effectiveness of the combined application of PN and EN is superior to PN or EN alone in improving nutritional status and respiratory muscle strength as well as in improving the short-term outcome in elderly patients in RICU..

The multi-potent differentiation capability of mesenchymal stem cells (MSCs) implies potential to achieve patient-specific regenerative therapy for myocardial infarction. However, it is evident that transplanted stem cells do not survive well in the harsh ischemic microenvironment. Erythropoietin (EPO) has been shown to be a potent inhibitor of neuronal and myocardial apoptosis. Here, we investigate the cell viability and the change of erythropoietin signal pathway of MSCs challenged by hypoxia treatment.Methods MSCs were derived from the bone marrow of 2-week-old Wistar rats and expanded. Hypoxia treatment of cells was performed using a ProOx-C-chamber with the oxygen concentration set to 0.5% for the times required.Results The rate of trypan blue staining was 3.5% ± 0.4% in control group, and 3.9% ± 0.2%, 5.0% ±0.5%, 7.1% ± 0.5% in the groups treated with hypoxia for 24, 48, 72, 96 hours. Western blot analysis suggested the expression of EPO in MSCs was significantly upregulated after 48-hour treatment with hypoxia, which was further confirmed by immunofluorescence staining. There was higher and earlier expression of EPOR. And the expression level of total ERK remained constant during the hypoxic treatment. However, the expression of HIF-1α phosphorylated ERK was significantly upregulated after 24-hour treatment with hypoxia and peaked at 72 hours.Conclusions MSCs is not sensitive to hypoxia insult alone. The components in EPO signal pathway (e. g.EPO, EPOR and P-ERK) is upregulated in MSCs after hypoxic treatment, which suggests that EPO signal pathway plays an important role in the hypoxia-tolerance and paracrine protecting capability of MSCs.
