In Situ Preparation of Tannic Acid-Modified Poly(-isopropylacrylamide) Hydrogel Coatings for Boosting Cell Response.

The improvement of the capability of poly(-isopropylacrylamide) (PNIPAAm) hydrogel coating in cell adhesion and detachment is critical to efficiently prepare cell sheets applied in cellular therapies and tissue engineering. To enhance cell response on the surface, the amine group-modified PNIPAAm (PNIPAAm-APTES) nanohydrogels were synthesized and deposited spontaneously on tannic acid (TA)-modified polyethylene (PE) plates. Subsequently, TA was introduced onto PNIPAAm-APTES nanohydrogels to fabricate coatings composed of TA-modified PNIPAAm-APTES (PNIPAAm-APTES-TA).

Efficacy and safety of a sequential treatment with clearing heat and eliminating phlegm and tonifying and activating blood circulation in treating acute ischemic stroke: study protocol for a randomized controlled trial.

Objective: To investigate the short-term efficacy and safety outcomes following a sequential treatment with clearing heat and eliminating phlegm (CHEP) formula and tonifying Qi and activating blood circulation (TQABC) formula in patients with acute ischemic stroke (AIS) within a 72 h time window.

Methods: In this randomized, multicenter, double-blinded, placebo-controlled trial, 500 participants will be randomly assigned in a ratio of 1∶1 to the CHEP+ TQABC group or control group. In addition to guideline-based standard medical care, participants in the treatment group will receive the CHEP formula for the first 5 consecutive days followed by the TQABC formula for another 10 consecutive days, while those in the control group will receive CHEP formula placebo and TQABC formula placebo consecutively.

Effect of Qizhitongluo capsule on lower limb rehabilitation after stroke: A randomized clinical trial.

Background: An individual's level of lower limb motor function is associated with his or her disability level after stroke, and motor improvement may lead to a better prognosis and quality of life. Data from animal models show that Qizhitongluo (QZTL) capsule facilitates recovery after focal brain injury. We aimed to validate the efficacy and safety of the QZTL capsule for promoting lower limb motor recovery in poststroke patients.

[Effect of modified Buyang Huanwu Decoction on hemorrhagic transformation after rt-PA intravenous thrombolysis in patients with super early cerebral infarction].

To study the effect of modified Buyang Huanwu Decoction on the hemorrhagic transformation after intravenous thrombolysis of recombinant tissue type plasminogen activator(rt-PA) in patients with super early(onset time<4. 5 h) cerebral infarction. From March 2016 to July 2018,at the brain disease zone of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine,212 cases of super early cerebral infarction were selected and divided into two group according to the randomized complete blocks designs: control group(106 cases) and traditional Chinese medicine group(106 cases).
