pH/enzyme dual sensitive Gegenqinlian pellets coated with Bletilla striata polysaccharide membranes for the treatment of ulcerative colitis.

Gegen Qinlian Decoction, derived from Zhang Zhongjing's Treatise on Typhoid Fever, has been widely used in the treatment of various common diseases, frequently-occurring diseases and difficult and complicated diseases, such as ulcerative colitis. In this study, Bletilla striata polysaccharide (BSP) was innovatively used as a film coating material to prepare Gegen Qinlian pellets with dual sensitivity of pH enzyme for the treatment of ulcerative colitis. BSP has the ability to repair the inflamed colon mucosa and can produce synergistic effects, while avoiding the adverse therapeutic effects caused by the early release of drugs from a single pH-sensitive pellets in the small intestine.

Distinguishing iron deficiency anemia from thalassemia by the red blood cell lifespan with a simple CO breath test: a pilot study.

Background: Extant indices for distinguishing between iron deficiency anemia (IDA) and thalassemia (Thal) have substantial practical limitations. The aim of this pilot study was to assess the predictive value of red blood cell lifespan (RBCLS), as determined by an automated CO breath test analysis approach, in the differential diagnosis of these two common forms of microcytic hypochromic anemia (MHA).

Methods: RBCLS measurements were conducted in 35 healthy controls (HCs) and 114 patients diagnosed with MHA (IDA, N = 59; and Thal, N = 55) with ELS TESTER that provides a direct RBCLS value read-out.

[Effects of Synthetic Long-Chain Polyphosphate on Blood Coagulation and Platelet Aggregation].

Objective: To investigate the effects of synthetic long-chain polyphosphate on blood coagulation and platelet aggregation.

Methods: The effect of artificial synthetic long chain poly phosphate on blood coagulation and platelet aggregation was detected by coagulation tests, coagulation factor activity detection and platelet aggregation test, and its mechanism was explored by ELISA, flow cytometry and high content imaging system.

Results: The long chain polyphosphates prolonged activated partial thromboplastin time, decreased coagulation factor FⅧ, FⅨ, FⅪ and FⅫ activity, blocked ADP-induced platelet aggregation, and decreased the concentration of calcium and TXA2 in platelet.
