ABSTRACT

OBJECTIVE@#To investigate whether atractylenolide Ⅰ (ATL-Ⅰ) has protective effect on lipopolysaccharide (LPS)-induced disseminated intravascular coagulation (DIC) in vivo and in vitro, and explore whether NF-κB signaling pathway is involved in ATL-Ⅰ treatment.@*METHODS@#New Zealand white rabbits were injected with LPS through marginal ear vein over a period of 6 h at a rate of 600 μg/kg (10 mL/h). Similarly, in the treatment groups, 1.0, 2.0, or 5.0 mg/kg ATL-Ⅰ were given. Both survival rate and organ function were tested, including the level of alanine aminotransferase (ALT), blood urine nitrogen (BUN), and TNF-α were examined by ELISA. Also hemostatic and fibrinolytic parameters in serum were measured. RAW 264.7 macrophage cells were administered with control, LPS, LPS + ATL-Ⅰ and ATL-Ⅰ alone, and TNF-α, phosphorylation (P)-IκBα, phosphorylation (P)-NF-κB (P65) and NF-κB (P65) were determined by Western blot.@*RESULTS@#The administration of LPS resulted in 73.3% mortality rate, and the increase of serum TNF-α, BUN and ALT levels. When ATL-Ⅰ treatment significantly increased the survival rate of LPS-induced DIC model, also improved the function of blood coagulation. And protein analysis indicated that ATL-I remarkably protected liver and renal as decreasing TNF-α expression. In vitro, ATL-I obviously decreased LPS-induced TNF-α production and the expression of P-NF-κB (P65), with the decrease of P-IκBα.@*CONCLUSIONS@#ATL-Ⅰ has protective effect on LPS-induced DIC, which can elevate the survival rate, reduce organ damage, improve the function of blood coagulation and suppress TNF-α expression by inhibiting the activation of NF-κB signaling pathway.

ABSTRACT

Objective To investigate whether atractylenolide (ATL-) has protective effect on lipopolysaccharide (LPS)-induced disseminated intravascular coagulation (DIC) in vivo and in vitro, and explore whether NF-κB signaling pathway is involved in ATL- treatment. Methods New Zealand white rabbits were injected with LPS through marginal ear vein over a period of 6 h at a rate of 600 μg/kg (10 mL/h). Similarly, in the treatment groups, 1.0, 2.0, or 5.0 mg/kg ATL- were given. Both survival rate and organ function were tested, including the level of alanine aminotransferase (ALT), blood urine nitrogen (BUN), and TNF-α were examined by ELISA. Also hemostatic and fibrinolytic parameters in serum were measured. RAW 264.7 macrophage cells were administered with control, LPS, LPS + ATL- and ATL- alone, and TNF-α, phosphorylation (P)-IκBα, phosphorylation (P)-NF-κB (P65) and NF-κB (P65) were determined by Western blot. Results The administration of LPS resulted in 73.3% mortality rate, and the increase of serum TNF-α, BUN and ALT levels. When ATL- treatment significantly increased the survival rate of LPS-induced DIC model, also improved the function of blood coagulation. And protein analysis indicated that ATL-I remarkably protected liver and renal as decreasing TNF-α expression. In vitro, ATL-I obviously decreased LPS-induced TNF-α production and the expression of P-NF-κB (P65), with the decrease of P-IκBα. Conclusions ATL- has protective effect on LPS-induced DIC, which can elevate the survival rate, reduce organ damage, improve the function of blood coagulation and suppress TNF-α expression by inhibiting the activation of NF-κB signaling pathway.

ABSTRACT

Objective To evaluate the quality of life of patients with diabetes mellitus in rural areas,and to analyze the main influencing factors.Methods The EQ -5D and questionnaire were used to collect information of patients with diabetes mellitus and to evaluate their quality of life.Logistic regression,multiple liner regression analyses and other statistical methods were used to analyze the related factors of life quality among rural patients with diabetes mellitus. Results A total of 416 patients with diabetes mellitus were investigated.The mean score of EQ -5D and EQ -VAS of all cases were 0.835 ±0.197 and 61.48 ±16.47 respectively,and the rates of the participants had problems at the dimensions of mobility,self -care,usual activities,pain/discomfort and anxiety/depression were 21.15%,11.54%,17.31%, 38.46% and 47.12% respectively.Logistic regressions for the five dimensions showed that complications were the common significant factors of all five dimensions,and age was related to the dimensions of mobility,usual activities,pain/discomfort and anxiety/depression.Gender and HbA1C were influencing factors of pain/discomfort dimension.Multiple liner regression analyses showed that the number of complications was the influencing factors of the valuation of EQ -5D and the score of EQ -VAS.Conclusion The quality of life among patients with diabetes mellitus in rural areas was lower than healthy people.Anxiety/depression was the most common problem,and complications were the main factor for the decrease of quality of life among diabetic patients.

ABSTRACT

<p><b>OBJECTIVE</b>This research intends to amplify the entire coding region sequences of SLC25A13 mRNA which encodes citrin, and to investigate sequence features of the transcripts for this gene in cultured human amniocytes. This study will provide laboratory evidence for prenatal diagnosis of neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) at mRNA level.</p><p><b>METHODS</b>One amniocyte sample was collected from a pregnant woman who underwent prenatal diagnosis of citrin deficiency and whose fetus has proven a carrier of 851del4 mutation by genomic DNA analysis. Another amniocyte sample, as a control, was from a fetus without family history of citrin deficiency. Total RNA was extracted from cultured amniocytes, cDNA was synthesized, and then nested-PCR was performed to amplify the entire coding region sequences of SLC25A13. The PCR products were cloned and analyzed by sequencing.</p><p><b>RESULTS</b>The entire coding region of SLC25A13 gene was successful amplified from two cultured human amniocytes. The splice variant of SLC25A13, SLCA (normal mRNA), was identified in the two samples. SLCB (CAG insertion between exon 9-10) was identified in the control. SLCC (exon 5-11 skipping), but not transcriptional product from the allele with 851del4 mutation, was identified in the 851del4 mutation carrier.</p><p><b>CONCLUSIONS</b>This study demonstrated that the entire coding region of SLC25A13 cDNA can be successfully amplified from two cultured human amniocytes, and revealed exon 5-11 skipping as a novel SLC25A13 transcript. Normal mRNA predominated in the transcripts in normal control and 851del4 mutation carrier, suggesting that the two fetuses were not at risk for NICCD. These SLC25A13 transcription features provided laboratory evidence for prenatal diagnosis of NICCD.</p>
