OBJECTIVE: To establish an HPLC-ELSD method to determine a new compound named Fructopyrano-(1 → 4)-glucopyranose in Radix Isatidis. METHODS: The HPLC method was conducted on an Agilent XDB-C18 column (4.6 mm × 150 mm, 5 μm), with methanol-water (5:95) as the mobile phase. The drift tube temperature was 115°C and flow fate of carrier gas was 3 L · min-1. RESULTS: The calibration curve was linear for FG in the range of 8.40 - 21.00 ng (r = 0.9990). The recovery was 97.27% - 102.72%. CONCLUSION: This method is accurate, reliable, rapid, sensitive, reproducible, and can be used for the determination of FG in Radix Isatidis.

Background Diabetic retinopathy (DR) is a common complication of diabetic mellitus,but its pathogenesis is still unclear.Adiponectin may restrain inflammatory reaction and reduce adhesion of vascular endothelial cell to influence diabetic microangiopathy.Relation between adiponectin and nitric oxide synthase (NOS)is less reported.Objective This study was to observe the effect of adiponectin on the expression of NOS in the retinas of diabetic rats.Methods Forty 8-10 weeks Sprague-Dawley (SD) female rats were collected.The rats were randomized into the normal control group (10 rats),adiponectin group (15 rats) and diabetic model control group (15 rats) using the random number table method.Tetraoxypyrimidine was intraperitoneally injected to establish the diabetic model in the rats of the adiponectin group and diabetic model control group,and 10 μg/kg of adiponectin was then injected into the rats of the adiponectin group.Western blot was used to detect the expression of the adiponectin protein in the rat retinas,and the expression of NOS in rat retina was located by immunochemistry.The use of the animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The relative amount of adiponectin (adiponectin/β-actin)in the retinas was 0.85 ± 0.21,0.79 ± 0.17 and 0.42 ± 0.08,respectively,in the normal control group,adiponectin group and diabetic model control group,with significant differences among the 3 groups (F =4.236,P =0.000).The adiponectin/β-actin ratio in the retinas of the diabetic model control group was significantly declined in comparison with the normal control group and adiponectin group (q =6.615,P =0.000 ; q =6.026,P =0.000).The NOS levels (A value) in the retinas were 0.244 ± 0.035,0.262 ± 0.032 and 0.367 ± 0.066,respectively,in the normal control group,adiponectin group and diabetic model control group,showing a significant difference among them (F =3.752,P =0.001).The A value of NOS in the diabetic model control group was significantly increased in comparison with the normal control group and adiponectin group (q =3.488,P =0.002 ; q =3.079,P =0.005).NOS expression was localized to the inner nuclear layer and retinal ganglion cell layer.Conclusions Adiponectin reduces NO content in diabetic rat retinas by regulating NOS expression.

Bile acids (BAs) are a major component of bile salt, which plays a vital role in the metabolism of lipids in humans. Ninety-five percent of bile acids are recycled by the enterohepatic circulation (EHC), and therefore EHC is essential for bile acid homeostasis. There are four transporters that mediate the transmembrane transport of bile acids, each of which plays an important role in the enterohepatic circulation. Gene defects in bile acid transporters can lead to disorders of the enterohepatic circulation, ultimately leading to clinical phenotypes such as metabolic diseases and even death. Bile transporter expression is altered in patients with various metabolic disease states, suggesting that disruption of bile acid transporters may be a pivotal pathological mechanism for the development of metabolism diseases. Thus, many drugs targeting bile acid transporters are being developed. We provide a concise overview of the progress of bile acid transporters research, discuss the relationship between different bile acid transporters and disease development, and summarize the current progress in drug development targeting bile acid transporters.

Objective Study on methylenetetrahydrofolate reductase(MTHFR)gene polymorphism in coronary heart disease.Methods Detect the MTHFR C677T gene polymorphism by PCR-RFLP in 73 cases of healthy individuals and 87 cases of coronary heart diseas(CHD).Results At the site of 677,the T allele frequencies are 18.5%,36.1%,respectively,for healthy individuals and 87 cases of coronary heart disease.The frequecies of MTHFR CT genotype and T allel were significantly higher in disease groups.There are significant differences between disease group and control group(P

Complexity algorithm and wavelet package transform are discussed in this paper. To improve the classification ability of complexity algorithm in motion pattern recognition, it's used together with wavelet package transform. This method shows a better performance than a single complexity algorithm.

Objective To explore the physical growth in infants with eczema who treated with regular use of glucocorticoid.Methods A total of 115 full-term infants newly diagnosed with eczema were included in this study and treated with topical glucocorticoids regularly.The severity of eczema was assessed and anthropometric indices were measured regularly.Results Both weight for age (WAZ) and length for age (LAZ) at birth and 6-month-old were higher than those of World Health Organization (WHO) child growth standards.However,the LAZ at diagnosis and 3 months after treatment were lower than that of WHO child growth standards.The weight,length,and the growth rate from birth to the time of diagnosis were all lower than those of WHO child growth standards.While the growth rate after treatment for 3 to 6 months was higher than that of WHO child growth standards.The increases of WAZ and LAZ were significantly different among three periods:at birth to diagnose,at diagnosis to 3 months after treatment,and 3 months to 6 months after treatment (P＜0.001).Conclusion In the early stage of eczema,the growth rate was decreased when the symptoms were not controlled.However,after treatment,the growth rate was increased.It is suggested that treatment of regular topical glucocorticoids has no adverse effects on growth of eczema infants,and also is beneficial to the catch-up growth of infants.

Objective:To observe the clinical efficacy of acupuncture plus umbilicus application with Chinese medicine for detrusor underactivity.Methods:A total of 46 male patients with detrusor underactivity who were admitted to our hospital between January and December 2017 were randomized into a control group and an observation group,with 23 cases in each group.The control group received intermittent catheterization and routine nursing,and the observation group was treated with acupuncture plus umbilicus application with Chinese medicine on the basis of the treatment of the control group.The comprehensive efficacy,the improvement of bladder urine residue and maximum flow rate of the two groups were observed.Results:No cases dropped out in the two groups.After the intervention,the total effective rate of the observation group was 78.3％,which was significantly higher than 52.2％ of the control group (P＜0.05).After intervention,the improvements of bladder urine residue and maximum flow rate in the observation group were statistically different from those in the control group (both P＜0.05).Conclusion:The combination of acupuncture and umbilicus application with Chinese medicine added on the basis of intermittent catheterization and routine nursing has a certain effect in treating male patients with detrusor underactivity,and is worth further clinical study.
