OBJECTIVEThis study investigated the thrombolitic effect of Tianma Xinnao capsule and its preliminary mechanism, as well as the effect on coagulation system.
METHODCharlton's and Tomihisa's methods were modified to investigate the thrombolytic effect of Tianma Xinnao capsule. The activities of type 1 plasminogen activator inhibitor (PAI-1) and tissue-type plasminogen activator (tPA) in rabbit plasma were assayed by use of ELISA. The effects of Tianma Xinnao capsule were also evaluated on euglobulin lysis time (ELT), prothrombin time (PT), kaolin partial thromboplastin time (KPTT), thrombin time (TT), fibrinogen (Fib) and hemorheology.
RESULTThe results showed that Tianma Xinnao capsule had a dose-dependent thrombolytic effect in rats. Tianma Xinnao capsule at 0.6 and 1.2 g x kg(-1) produced 40% and 50% of reperfusion rate, while obtained 50% and 40% of reocclusion rate; 0.3 g x kg(-1) of Tianma Xinnao capsule, however, had no effect on the reperfusion or reocclusion rate. Tianma Xinnao capsule significantly inhibited PAI-1 activity, while elevated tPA activity in rabbit plasma. Tianma Xinnao capsule markedly prolonged ELT, PT, and KPTT, and decreased Fib level. Tianma Xinnao capsule showed no significant influence on TT or high, medium, or low sheering viscosity.
CONCLUSIONIt is indicated that Tianma Xinnao capsule inhibited PAI-1 activity and increased tPA activity, and this property of Tianma Xinnao capsule is assigned to be responsible for the thrombolytic effect.

Differential proteome profiles of human lung squamous carcinoma tissue compared to paired tumor-adjacent normal bronchial epithelial tissue were established and analyzed by means of immobilized pH gradient-based two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS). The results showed that well-resolved, reproducible 2-DE patterns of human lung squamous carcinoma and adjacent normal bronchial epithelial tissues were obtained under the condition of 0.75-mg protein-load. The average deviation of spot position was 0.733+/-0.101 mm in IEF direction, and 0.925+/-0.207 mm in SDS-PAGE direction. For tumor tissue, a total of 1241+/-88 spots were detected, 987+/-65 spots were matched with an average matching rate of 79.5%. For control, a total of 1190+/-72 spots were detected, and 875+/-48 spots were matched with an average matching rate of 73.5%. A total of 864+/-34 spots were matched between tumors and controls. Forty-three differential proteins were characterized: some proteins were related to oncogenes, and others involved in the regulation of cell cycle and signal transduction. It is suggested that the differential proteomic approach is valuable for mass identification of differentially expressed proteins involved in lung carcinogenesis. These data will be used to establish human lung cancer proteome database to further study human lung squamous carcinoma.

Background::Helicobacter pylori ( H. pylori) infection is an infectious disease with a prevalence rate of up to 50% worldwide. It can cause indigestion, gastritis, peptic ulcer, and gastric cancer. H. pylori eradication treatment can effectively control disease progression and reduce the risk of the above conditions. However, the escalating trend of antibiotic resistance presents a global challenge for H. pylori eradication. We aim to provide guidance on pharmacological treatment of H. pylori infection. Methods::This clinical practice guideline is developed following the World Health Organization’s recommended process, adopting Grading of Recommendations Assessment, Development and Evaluation in assessing evidence quality, and utilizing Evidence to Decision framework to formulate clinical recommendations, minimizing bias and increasing transparency of the clinical practice guideline development process. We used the Reporting Items for practice Guidelines in HealThcare (RIGHT) statement and The Appraisal of Guidelines for Research and Evaluation II (AGREE II) as reporting and conduct guides to ensure the guideline’s completeness and transparency.Results::Though decreasing in developed countries, the prevalence of H. pylori remains high in developing countries, causing a major public health burden. This clinical practice guideline contains 12 recommendations concerning pharmacological treatment for H. pylori eradication. Among them, it is worth highlighting that bismuth preparations are inexpensive, safe, and effective, consequently making bismuth quadruple therapy a preferred choice for initial and rescue treatment. In empirical treatment, high-dose dual therapy is equally effective compared with bismuth quadruple therapy. Conclusions::The 12 recommendations in this clinical practice guideline are formed with consideration for stakeholders’ values and preferences, resource use, feasibility, and acceptability. Recommendations are generalizable to resource limited settings with similar antibiotic resistance pattern as China, and lower middle-income countries facing comparable sociological and technical challenges.Registration::Guidelines International Network (GIN) website, https://guidelines.ebmportal.com/node/69996.
