I uptake of thyroid and color Doppler flow imaging (CDFI) of superior thyroid artery (STA) were performed in 20 patients with Graves′ disease (GD) and 19 patients with other causes of hyperthyroidism. Maximum velocity and diameter of STA in patients with GD were much higher than those in non-GD group. CDFI of STA seems to be a useful tool in differential diagnosis of hyperthyoidism.

OBJECTIVETo investigate the effects of total flavonoids of propolis (TFP) on apoptosis of myocardial cells of chronic heart failure and its possible mechanism in rats.

METHODSSix male SD rats were randomly selected as normal control group, the remaining rats were made as chronic heart failure (CHF) model by intraperitoneal injection of adriamycin. The rats in the successful model were randomly divided into five groups (n = 6): CHF group, total flavonoids of propolis low dose group (LD group), total flavonoids of propolis middle dose group (MD group), total flavonoids of propolis high dose group (HD group), digoxin group (DIG group). After six week treatment, cardiac function indexes of rats were recorded by signal acquisition system; brain natriuretic peptide (BNP), cardiac troponin I (cTnI), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) content in plasma were detected; Myocardial morphological changes and collagen fiber hyperplasia by HE and Masson staining were observed; Myocardial apoptosis was detected with TUNEL method and protein connexin 43(P-Cx43) expression was detected by Western blot method.

RESULTSCompared with NC group, left ventricular systolic pressure(LVSP) and maximal rise/fall velocity of left ventriculad pressure (± dP/dt(max)) absolute value in CHF group were significantly lowered (P < 0.01) while left ventricular end diastolic pressure (LVEDP) was increased significantly (P < 0.01); Contents of plasma BNP, cTnI, TNF-α and IL-6 in the CHF group were significantly improved (P < 0.01). Compared with CHF group, LVSP, ± dP/dt(max) absolute value in MD and HD groups were increased (P < 0.05), and LVEDP was significantly lowered (P < 0.01); LVEDP in LD group was significantly lowered (P < 0.01), changes in LVSP and ± dp/dt(max) absolue value were not obvious (P > 0.05). BNP, cTnI, TNF-α and IL-6 contents in MD and HD groups were significantly reduced (P < 0.01), but those plasma indicator changes were not obvious in LD group (P > 0.05). Western blot showed that P-Cx43 expression in CHF group was significantly higher than that in NC group (P < 0.01) and that in all TFP treatment groups it was decreased compared with CHF group (P < 0.05, P < 0.01), among which pairwise comparisons also showed differences (P < 0.05), myocardial apoptosis index (%)(22.62 ± 3.39) in CHF group was higher than that in NC group( 1.12 ± 0.24) (P < 0.01); compared with CHF group, the apoptosis index of myocardial cells (%) in LD,MD and HD groups, (15.79 + 2.8), (9.28 + 2.1) and (4.73 + 1.14) respectively, were significantly lower than those in the CHF group( P < 0.01). The expression level of P-Cx43 positively correlated with the apoptotic index (r = 0. 861, P < 0.01).

CONCLUSIONTotal flavonaids of propolis have inhibitory effect on apoptosis of myocardial cells of chronic heart failure induced by adriamycin in rats, and the mechanism may be closely related to the regulation of Cx43 expression, especially the regulatory phosphorylation status.

Based on ultra high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS), a rapid and simultaneous quantitative method for the measurement of seven components (kinsenoside; rutin; kaempferol-3-O-rutinoside; quercimeritrin; narcissin; isorhamnetin-3-O-glucoside; quercetin) of A. roxburghii was established. The separation was performed over 8.0 minutes on a Waters Acquity UPLC BEH Shield RP18 (2.1 mm × 100 mm; 1.7 μm) with a mobile phase consisting of acetonitrile (A) and 0.1% formic acid water solution (B) with gradient elution at a flow rate of 0.2 mL·min^-1; the column temperature was 30 ℃ and the injection volume was 2 μL. Electrospray spray ionization source (ESI source) was used for mass spectrometry, and positive and negative ion modes were detected at the same time. The results showed good linearity (R² ≥ 0.998 0), with good precision, repeatability and stability, and the average recovery was 97.71%-103.33%. Through cluster heat map and redundancy analysis, we found that kinsenoside was mainly distributed in stems, followed by leaves, and the lowest content in roots. The content of kinsenoside increased significantly in the stems of plants 6 months, but less change was evident in the roots and leaves. Flavonoids and flavonoid glycosides were mainly distributed in leaves. The UHPLC-MS/MS method established in this paper can be used for the quality control of A. roxburghii and provides a reference for establishing a more comprehensive quality detection method for this medicinal.

In this paper, the process performance indexes (PPIs) P(p) and P(pk) were introduced and applied to evaluate the process capability and quality consistence of Chinese medicine products. The historical quality analysis data of Qingkailing injection were collected and taken as the research object. The confidence intervals of P(p) and P(pk) were estimated based on the Bootstrap sampling methods. Results showed that the value and width of the confidence interval P(p) of were smaller that of P(pk) suggesting that the P(pk) index was more sensitive than P(p) in process capability analysis. Within the production period concerned, the P(pk) values estimated from different quality indexes of Qingkailing injection, such as baicalin, cholic acid, geniposide and total nitrogen, were 1.122, 2.055, 1.564 and 0.891, respectively. It could be found that the cholic acid had the highest process capability, followed by the geniposide and baicalin. The total nitrogen had the lowest process capability, indicating that it is necessary to reinforce the quality management of total nitrogen related manufacturing processes. The case studies demonstrate the effectiveness and feasibility of PPIs, which are convenient to be used in production practice of Chinese medicine.

OBJECTIVETo provide a theoretical basis for the further development of new drugs, the analgesic and anti-inflammatory effects and the liver function in mice of anthocyanin from Ligustrum vicaryi were investigated.

METHODSThe 240 experimental mice were splitted equally for 6 kinds of experiments and 40 rats in each kind of experiment were divided into 5 groups (n = 8): normal saline control group (NS); aspirin control group (Asp); high-concentration anthocyanin group (HA); medium-concentration anthocyanin group (MA); low-concentratior anthocyanin group (LA). The analgesia effect of anthocyanin at different concentration was detenmined by hot-plate test and acetic acid writhin test, and the anti-inflammatory effect of anthocyanin was performed by ear edema, ahdomen capillary permeability and cotton granuloma. The activities of superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) and the contents of nitric oxide (NO) and prostaglandin E2 (PGE2) in blood serum were determined, and the activities of SOD, T-AOC and glutathione peroxidase (GSH-Px) in liver were measured, while the histological changes of liver tissue were observed.

RESULTSThe pain threshold of mice was enhanced and the times of twist body wa decreased by medium-concentration and high-concentration anthocyanin. The activity of SOD was increased and the conentrs of NO and PGE were reduced in blood serum. High-concentration anthocyanin inhibited the ear swelling , the increase of celiac capillary permeability and th granuloma hyperplasia, and increased the activities of SOD and T-AOC while decreased the content of PGE2. The activities of SOD, T-AOC. GSH-PX were increased in liver, but the morphology of liver tissues in each group had no significant changes.

CONCLUSIONAnthocyanin Ligustrum vicaryi has definite anti-inflammatory and analgesic effects, which is related to increasing the antioxidant capacity and decreasing th contents of NO and PGE2, and has not obvious damage to liver in the range of experimental concentration.

The antitussive activity assay for the root extraction of Disporum cantoniense was carried out with coughing mice induced by ammonia liquor. The results showed that the ethanol and water extractions of D. cantoniense possess strong antitussive activity, and the high dose of the former was better than positive control, and then the constituents of the ethanol extraction were separated and purified by various modern chromatographic techniques. Their structures were identified by physico-chemical properties and spectroscopic data. As a result, eight compounds were isolated and identified as stigmast-4-en-3-one(1), (22E, 24R)-ergosta-5, 7, 22-trien-3beta-ol(2), obtucarbamate A(3), obtucarbamate B(4), neotigogenin(5), azo-2, 2'-bis[Z-(2,3-dihydroxy-4-methyl-5-methoxy) phenyl ethylene] (6),dimethyl {[carbonylbis (azanediyl)] bis( 2-methyl-5, 1-phenylene) j dicarbamate (7) , and quercetin-3-O-pB-D-glucopyranoside(8). All compounds were isolated from this plant for the first time, and the result of bioactivity-directed isolation showed that compounds 3, 4, and 6 had obvious effect on antitussive activity, and compound 6 had the same level as positive control.
