Objective To discuss the present situation of nearly five years of traditional Chinese medicine for the diagnosis and treatment of children with bronchial asthma,confirmed that the curative effect of traditional Chinese medicine for the treatment of the disease is reliable,thus to provide certain theoretical basis for further research in the future.

To investigate the changes of cardiac myosin ATPase and its isoenzyme in early stage of cardiac hypertrophy following myocardial infarction(MI), we studied myosin ATPase activitzy, isoenyme distriibution and myocardial fiber diameter of uninfarcted ventricu lar sfptum, 9 aed 21 days after operation in MI rats. The results showed that coincident with the increases in myocardial fiber diameter on 9 days after MI, both myosin ATPase activity and V_1 isoenzyme amount were depressed. These changes were more pronounced on 21 after MI. It is suggested that with the development of myocardial hypertrophy in early stage of MI, adaptive changes in myosin ATPase activity and isoenzyme distribution occur.

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by polyarthritis.Numerous agents with varying mechanisms are used in the treatment of RA,but there is no radical cure.Interleukin-6 (IL-6) plays an important role in the pathogenesis of RA.Agents targeting IL-6 such as tocilizumab (TCZ) attracted significant attention as a promising agent in RA treatment.This article reviewed the key efficacy and safety data from clinical trials of TCZ,as well as six candidate IL-6 blockers including sarilumab,ALX-0061,sirukumab,MEDI5117,clazakizumab,and olokizumab,and their future perspectives in the treatment of RA.

Objective To study the effect of baicalin on the expression of receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG) in cultured human periodontal ligament (HPDL) cells. Methods Small interfering RNA (siRNA) eukaryotic expression vector targeted transforming growth factor βⅡ receptor (TGF-β RⅡ) was constructed and transfected into T cells. HPDL cells with T cells transfected with siRNA or not were placed in the culture medium that had been added with lipopolysaccharide (LPS) and baicalin. The obtained solution was divided into six groups according to the components (group Ⅰ: HPDL cells+LPS+T cells transfected with siRNA1+baicalin;group Ⅱ: HPDL cells+LPS+T cells transfected with siRNA1; group Ⅲ: HPDL cells+LPS+T cells+baicalin; group Ⅳ: HPDL cells+LPS+T cells; group Ⅴ: HPDL cells+baicalin; group Ⅵ: HPDL cells) and was cultured for 48 hours. RT-PCR was used to observe the effect of baicalin on the expression of OPG-RANKL in HPDL cells. Results The ratio of RANKL/OPG in group Ⅰ was lower than that in group Ⅱ (P<0.01) and higher than that in group Ⅲ (P<0.01); The ratio of RANKL/OPG in gronp Ⅲ was lower than that in group Ⅳ (P<0.01); the ratio of RANKL/ OPG in group Ⅳ was higher than that in group Ⅵ (P<0.01); the ratio of RANKL/OPG in group Ⅴ was lower than TGF-β signaling transduction plays an important role in the effect of baicalin on the RANKL/OPG ratio in HPDL cells.

Objective:To establish a headspace GC method for the determination of 7 kinds of residual solvents in bicalutamide, including dichloromethane, n-hexane, tetrahydrofuran, ethanol, ether, acetone and ethyl acetate. Methods: The residual solvents in the substance were determined by GC equipped with an FID detector and linked with an Agilent DB-624 capillary column (30. 0 m × 0. 25 mm × 1. 4 m). The inlet temperature was 200℃ and the FID detector temperature was 250℃. The column temperature was raised by program:the initial temperature was 35℃, maintained for 13 min, raised to 180℃ with a rate of 100℃/min, and maintained for 5 min. The carrier gas was nitrogen and the flow rate was 1. 2 ml·min-1. The heated temperature of the headspace oven was 90℃, the heated time lasted 30 min, and the injection volume was 1. 0 ml. The solution medium was dimethyl sulphoxide (DMSO). Results:Each solvent could be completely separated, and the calibration curve of each solvent showed good linear relationship with good accuracy. Conclusion:The method can be applied for the determination of residual solvents in bicalutamide.

Hypertension in children is defined as systolic blood pressure and/ or diastolic blood pressure≥95th percentile for age,gender and height,on at least 3 occasions. Persistent hypertension despite non - pharmacologic measures should be treated with anti - hypertensive drugs. Angiotensin - converting enzyme inhibitors,angiotensin receptor blockers,calcium channel blockers,β - blockers and diuretics are safe,effective,and well tolerated in children. This article describes the selection and clinical application of anti - hypertensive drugs in children.

There has been a growing number of prostate cancer patients in our country,and most of the patients suffer with bone metastases.Although more and more new drugs are reported for the treatment of prostate cancer,tumor local recurrence or metastasis occur within the 10 years after treatment.The diagnostic sensitivity of 18F-NaF PET/CT for bone metastases from prostate cancer is high.18F-NaF PET/CT not only can locate the lesion precisely,evaluate the drug efficacy quantitatively,but also can be used to follow up prostate cancer patients.This review is focused on the application of 18F-NaF PET/CT in bone metastases from prostate cancer.

OBJECTIVE:To establish a method for simultaneous determination of puerarin,berberine hydrochloride and ba-icalin in Erxieting syrup. METHODS:HPLC was performed on the column of Kromasil-C18 with mobile phase of methanol-0.2%Phosphoric acid solution (gradient elution) at flow rate of 1.0 ml/min,column temperature was 30 ℃,detection wavelength was 275 nm,and the volume injection was 10 μl. RESULTS:The linear was 10.43-83.44 μg/ml for puerarin,10.71-85.68 μg/ml for ber-berine hydrochloride and 12.58-100.64 μg/ml for baicalin(r≥0.999 3);RSDs of precision,stability and reproduciblity tests were lower than 2%;recoveries were 98.25%-100.87%(RSD=0.92%,n=6),99.41%-101.40%(RSD=0.68%,n=6)and 98.13%-99.76%(RSD=0.57%,n=6),respectively. CONCLUSIONS:The method is simple,reliable,can be used for the quality control of Erxiet-ing syrup.

We observed the effects of testosterone (T) on myosin ATPase activity and its isoenzyme distribution of noninfarcted myocardium in male infarcted rats. 21 days after myocardial infarction (MI), both myocardial fiber diameter and myosin ATPase activity were increased in T treated MI group when compared with that of the MI group (P

The correlation between vegetarian diets and cardiovascular health is always one of the hotspots. Many scholars have performed so many clinical researches all over the world, providing evidence-based medicine (EBM) reference for clarifying their correlation. In this paper, we raise ideas and expectation on the basis of a Meta-analysis about vegetarian diets and blood pressure (published on JAMA Internal Medicine in Feb 2014) in combination of main clinical research literature in this field in recent 20 years.
