Objective To investigate the distribution of blood pressure and incidence of hypertension in children and adolescents from the urban area of Guiyang city aged 8-17 years old,in order to provide scientific evidence for preventing hypertension.Methods Seven thousand nine hundred and sixty-three primary and secondary students were sampled and standardized in blood pressure,height and weight.In accordance with the Working Group on Obesity in China(WGOC)recommendations,the subjects were divided into overweight,obesity and normal weight group,then the relationship between blood pressure and body mass index(BMI)and the prevalence of hypertension in different BMI groups were analyzed.Results 1.Compared with the USA and Shanghai city,the distribution of blood pressure in children and adolescents from the urban area of Guiyang city were different(Pa

Objective To investigate the chemical constituents and activities of Linum usitatissimum L.aboveground. Meth-ods The chemical constituents were separated through silica gel,ODS,Sephadex LH-20,and semi-preparative RP-HPLC chroma-tography and identified by optical rotation and spectroscopic analysis. All of the isolates were evaluated for their inhibitory activities by the luciferase assay. Results Eight dibenzylbutyrolactone lignans were separated from L. usitatissimum and identified as(-)-hinoki-nin(1),(-)-bursehernin(2),(-)-dimethylmatairesinol(3),(-)-yatein(4),(-)-thujaplicatin trimethyl ether(5),nemerosin (6),(+)-E-7,8-dehydromatairesinol dimethyl ether(7),and E-7,8-dehydrothujaplicatin trimethyl ether(8),respectively. Conclu-sion Compounds 7 and 8 were isolated from L. usitatissimum for the first time,and NMR spectral data of compound 8 were reported for the first time. Compounds 1 and 3 showed moderate inhibitory activities on IL-6/STAT3 signaling pathway with IC50 values of 42.12 and 43.43μmol/L,respectively.

Mild cognitive impairment (MCI) is a transitional stage between normal aging and dementia. The main characteristic of the patients with MCI is the impairment of episodic memory in which hippocampus plays an important role. Therefore, the detection of structural and functional changes of hippocampus will be the key to early diagnosis of MCI. This paper presents a brief overview of recent study about hippocampal magnetic resonance imaging of MIC.

AIM: To study the protection of extract of Radix Atragali composite against acute hepatic injury. METHODS: Fed with the extract of Radix Atragali composite, m ice were injected with D-galactosamine intraperitoneally (800 mg/kg) and rats were i njected with carbon tetrachloride hypodermically (5 mL/kg) to induce acute hepat ic injury on the 8th day. ALT, AST and bilirubin in serum were examined. Patholo gical changes of liver tissue were observed. RESULTS: Compared with model group, activities of ALT and AST, c oncentrations of bilirubin were markedly decreased and pathological scores also showed that degeneration and necrosis of hepatic cell were lighter in the the ex tract of Radix Atragali composite treatment group. CONCLUSION: The extract of Radix Atragali composite attenuat es hepatic injury induced by D-galactosamine or carbon tetrachloride.

Objective To investigate the role of skin homing T lymphocytes in the development of psoriasis vulgaris(PV). Methods Indirect immunofluorescent double staining technique was employed to study the expression of infiltrating skin homing T lymphocytes in normal, uninvolved perilesional and lesional psoriatic skin in different stages (progressing, stable or regressing) and in normal human skin. Results ①Expression of cutaneous lymphocyte associated antigen (CLA) was found in the majority of CD3+T lymphocytes in normal human skin and in lesions of PV, and CD45RO phenotype was expressed in almost all CLA+T lymphocytes. ②In psoriatic lesions, the number of CD4+CLA+and CD8+CLA+cells was higher in progressive stage than that in stable stage(P

Objective To observe the intimal changes of inferior caval vein(ICV) wall after combined thrombolysis and anticoagulation therapy for acute thrombosis in rats.Methods The inferior caval venous thrombosis model was established in 105 rats and they were randomly diride into 3 treated groups:heparin(A) treatment group(n=35),urokinase(B) treatment group(n=35),and combination of urokinase and heparin(C) treatment group(n=35),and also eslablished a sham(D) group(n=30).The thrombosed caval veins were taken 1,4,7,14,and 28 d after thrombosis.Changes of thrombus structure and orgainization and intimal hyperplasia were observed by light microscope.The expression areas of collagen fiber were measured by histochemistry.Scanning electron microscopy was used to observe the damage of endothelial cells.Results The intimal hyperplasia in A group was the most severe.The expression area of collagen fiber in group C was less than that of A and B groups(P

BACKGROUND:Studies have found that peripheral blood stem cel s can highly differentiate into vascular endothelial cel s to promote blood vessel regeneration, and improve col ateral circulation, thereby achieving satisfactory outcomes in the treatment of limb ischemia. OBJECTIVE:To observe the clinical effect in diabetic lower extremity vascular disease patients undergoing percutaneous transluminal angioplasty combined with autologous peripheral blood stem cel transplantation. METHODS:Fifty patients hospitalized for diabetic lower extremity vascular disease from March in 2011 to December in 2014 were col ected:25 cases underwent percutaneous transluminal angioplasty as control group;another 25 underwent percutaneous transluminal angioplasty combined with autologous peripheral blood stem cel transplantation as combination group. At 1, 6, 12 months after surgery, subjective scores of affected limb pain and cold sensation were recorded, additional y, objective indicators, including ankle-brachial index, transcutaneous oxygen partial pressure, and claudication distance were detected. RESULTS AND CONCLUSION:Ankle-brachial index scores of the two groups were significantly increased, especial y at 1 month after surgery, but decreased at 6, 12 months, and there was a significant difference compared with that before treatment (P<0.05);at 1, 6, and 12 months, there was no significant difference between the two groups (P>0.05). At 1, 6, and 12 months after surgery, both of transcutaneous oxygen partial pressure and claudication distance in the two groups were significantly increased compared with those before treatment (P<0.05). Furthermore, compared with the control group, these two indicators in the combination group were significantly increased (P<0.05). Within 12-month follow-up, affected limb pain and cold sensation were improved in the two groups, especial y in the combination group. Inevitably, three cases had hypocalcemia during the col ection of peripheral blood stem cel s, and two cases developed fever and 3 cases appeared to have local exudation after surgery. All these symptoms were released by symptomatic treatments, respectively. In conclusion, percutaneous transluminal angioplasty combined with autologous peripheral blood stem cel transplantation for diabetic lower extremity vascular lesions can promote the establishment of affected limb col ateral circulation, to decrease the risk of limb ischemia, which achieves significant outcomes than percutaneous transluminal angioplasty used alone.

Objective To establish an HPLC fingerprint ofJinjing solid beverage,and provide experimental evidence of evaluating its quality.Methods Ten batches ofJinjing solid beverage were analyzed by HPLC under the gradient elution condition. A Kromasil C18 column(4.6 mm×250 mm, 5μm) was used, and the flow phase was acetonitrile-H2O(acidified to 0.1% with phosphoric acid) with gradient elution, and the detection wavelength was 327 nm, and the flow rate was 1.0 ml/min, and the column temperature was 35℃. The data were evaluated by the similarity evaluation software for TCM fingerprint.Results The HPLC fingerprint ofJinjing solid beverage were established. Twelve common peaks including chlorogenic acid were identified with similarity of more than 0.9.Conclusion HPLC method is a reliable, available and quick method, that provides a means for controlling and evaluating the quality ofJinjing solid beverage.
