Objective To determine the influence of total glucosides of paeony (TGP) on bone density, protein level of skeletal muscle and relative cytokine of osteoporotic rats. Methods Six-month-old SD rats were shamed as control (8 rats) or were ovariectomized (24 rats). The ovariectomized (16 rats) +TGP low dose and high dose group were treated with 50 mg/(kg?d) TGP and 150 mg/(kg?d) TGP respectively for 12 weeks. After the animals were sacrificed, IL-6, TNF-?, IGF-1, TGF-? in serum, protein level of skeletal muscle in right quadriceps femoris, and bone density of right femur and lumbar vertebra were determined. Results Compared with the ovariectomized group, the bone density and the protein level of skeletal muscle in TGP group increased significantly from the baseline (P

Objective To study the value of MSCT angiography(MSCTA)in diagnosing lower extremities arterial disease (LEAD) of diabetic foot ulcers and analyze the possible influential factors on the onset of diabetic foot ulcers.Methods 80 diabetic patients for MSCTA examination were divided into two groups by whether combined with foot ulcers.The tibial artery calcification score (TACS) and peripheral arterial occlusion index (PAOI) were calculated and the possible risk factors of diabetic foot ulcer were analyzed.Results There were 30 cases suffered with foot ulcer and 18 cases occurred lower extremity arterial occlusion (LEAO), the average PAOI was 4.40(3.60, 5.75).Non-foot ulcer cases were 50, and there were 8 cases suffered with LEAO, the average PAOI was 2.05(1.43, 3.10).Compared to patients without foot ulcer, patients with foot ulcer were older, had a lower BMI, and were more likely to have a history of tobacco use.They usually had higher TACS and severer peripheral arterial occlusive disease (PAOD).Stepwise regression model showed that foot ulcers had significant correlation with TACS and PAOI.Partial correlation analysis showed TACS was independent from PAOI in impacting diabetic foot ulcer.Conclusion MSCTA has important clinical value in diagnosing and valuing diabetic foot ulcer LEAD.Age, smoking history,BMI,TACS and PAOI affect the incidence of diabetic foot ulcers, and TACS and PAOI are the independent risk factors for diabetic foot ulcers.

Objective To explore effect of probiotics on improving the feeding intolerance in very low birth weight infants(VLBWI). Methods Sixty cases of VLBWI were randomly divided into two groups, 30 infants as therapy group,another 30 infants as control group.All infants in two groups were given aggressive intravenous nutrition and enteral feeding with preterm formulars. At the same time, probiotics were administered combined with preterm formulars to infants in therapy group. Milk amount, gastric residual, initial time of enteral feeding, time required for full enteral feeding and body weight on day 21 after birth were all recorded.Results Rate of no gastric residual increased significantly in therapy group compared with that of control group(t=6.24 P

Objective To explore the influence of Clostridium butyricum on the expression of vascular endothelial cell growth factor (VEGF) and its receptor 2 (VEGFR-2), proliferating cell nuclear antigen (PCNA), and tight junction protein claudin-2 in intestinal tissue in newborn rat with necrotizing enterocolitis (NEC). Methods Forty-eight-hour-old Sprague-Dewley (SD) rats were randomly divided into model group, control group, low-dose group, mid-dose group, and high-dose group, 12 rats each. Rats in each group were fed with milk substitute. The NEC model were created by hypoxia and cold stimulation for 3 consecutive days in model group, low-dose group, mid-dose group, and high-dose group. Meanwhile, low-dose group, mid-dose group, and high-dose group were intervened by being fed with Clostridium butyricum 0.2, 0.4, and 0.8 g/(kg·d), respectively. All rats in each group were sacriifced on day 4 and the intestines tissue was obtained. The pathological changes had been observed. The expression of VEGF, PCNA, and claudin-2 were detected by immunohistochemistry. The expression of VEGFR-2 was detected by RT-PCR. Results The intestines pathological scores was signiifcantly different among ifve groups (P?0 . 05 ). Conclusion The expression of VEGF, VEGF-2 , and claudin-2 were higher in rats with NEC, while the expression of PCNA was lower. Supplementation of Clostridium butyricum may protect newborn rats by its act on these factors.

Objective To study the effect of decitabine treating elderly patient with myelodysplastic syndrome-ring sideroblastic refractory anemia (MDS-RAS) and review the literatures. Methods Decitabine treated a patient with MDS-RAS four courses, at the dose of 25 mg everyday for 5 days per course. Observed the change of symptoms, peripheral blood cell counts, myelogram, T cell polarization, cellular immunity,chromosome. Determined the curative effect combined with efficiency standard of WHO 2008. Results The clinical symptoms got better after two courses. Peripheral blood cell counts began to get better after one course. The number of leukocyte, hemoglobin and platelet got nearly normal after four courses. After two courses, T cell polarization state got normal, the number of iron ring promyelocyticin bone marrow declined from 16 % to 0 and chromosome changed from complex karyotype to normal. Conclusion Decitabine is an effective drug to the old patient with MDS-RAS. But it needs to increase the number of cases and follow up long-term to observe the effective rate and long-term efficacy.

Objective To observe the effects of Dengzhanhua Capsule on kidney tissue inflammatory cytokines in chronic renal failure rats;To explore its possible mechanism for the efficacy in chronic renal failure. Methods Sixty SD rats were randomly divided into normal control group, model group, benazepril group and Dengzhanhua group, 15 rats in each group. Chronic renal failure rat model was established by Platt 5/6 nephrectomized. Benazepril (0.29 mg/100 g) was given to rats in the benazepril group by gastrogavage. Dengzhanhua Capsule (0.3 g/100 g) was given to rats in the Dengzhanhua group by gastrogavage. Normal saline was given to rats in the normal group and the model group by gastrogavage. The whole treatment period was twelve weeks. Expressions of TGF-β1 and PAI-1 were determined by semi-quantitative RT-PCR after treatment. Concentrations of kidney tissue inflammatory cytokines IL-6 and TNF-α were determined by ELISA. Results Expressions of TGF-β, PAI-1 and IL-6, TNF-αin benazepril group and Dengzhanhua group were significantly lower than those in model group (P<0.05). Compared with benazepril group, it was significantly lower in Dengzhanhua group (P<0.05). Conclusion Dengzhanhua Capsule can reduce kidney tissue inflammatory in chronic renal failure rats, and inhibit renal fibrosis.

Objective To explore the effects and mechanism of bexarotene in combination with tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) on apoptosis of leukemic cell line KG1a. Methods KG1a cells at logarithmic growth phase were obtained, and were divided into TRAIL group, bexarotene group, 300 ng/mL TRAIL in combination with bexarotene group and 2.0 μmol/L bexaroten in combination with TRAIL group. Cell apoptosis rate was detected in each group by flow cytometry. Flow cytometry was also employed to determine the apoptosis rates of KG1a cells after treatment with bexarotene and TRAIL in different sequences. The expression of Fas associated death domain-like IL-1 beta converting enzyme inhibitory protein (c-FLIP) was detected by Western blotting. Results There was no significant difference in cell apoptosis rates between TRAIL group and bexarotene group of each concentration (except for bexarotene 2.0 μmol/L) (P > 0.05). The cell apoptosis rates of 300 ng/mL TRAIL in combination with bexarotene group and 2.0 μmol/L bexaroten in combination with TRAIL group were significantly higher than those in TRAIL group and bexarotene group of each corresponding concentration (P <0.01). Sequential analysis revealed that bexarotene could reverse the resistance of KG1a cells to TRAIL (P < 0.001). Compared with single use of 2.0 μmol/L bexarotene or 300 ng/mL TRAIL, combination use could significantly down-regulated the expression of c-FLIP (P < 0.05). Conclusion Bexarotene can significantly enhance the apoptosis of KG1a cells induced by TRAIL, which may be attributed to the down-regulation of c-FLIP expression.

Thirty seven patients with congestive heart failure (CHF) were divided into cilazapril group (n=19) and general treatment group (n=18). Serum levels of interleukin-6 (IL-6) ,interleukin-8 (IL-8) , interleukin-10(IL-10) and tumor necrosis factor-α(TNF-α) , left ventricular ejection fraction (LVEF) ,left ventricular end-diastolic diameter (LVEDD), cardiac output (CO) and fractional shortening (FS) were measured before and after treatment. Serum levels of cytokines were also measured in 40 healthy individuals (control group). Results: The serum levels of IL-6, IL-8, IL-10 and TNF-α in CHF patients were significantly higher than those in the control group ( all P<0.01 ) ; After treatment, the serum IL-6, IL-8 and TNF-α were significantly decreased (P<0.01 ,P<0.05 ) in the cilazapril group. The LVEF, FS, CO were significantly increased in the Cilazapril group ( P<0.01 ) ; And the serum levels of IL-6 were significantly decreased in the cilazapril group as compared with the general treatment group ( P<0.05 ), however, after treatment, the EF, LVEF, FS and CO had no statistical differences in the cilazapril group as compared with the general treatment group. In the control group only LVEF and FS improved(P<0.01) ; Cytokine levels showed no changes. It suggests that cilazapril can reduce the serum levels of pro-inflammatory cytokines, increased the serum levels of anti-inflammatory cytokine, protect and improved cardiac function in the patients with congestive heart failure.
