Towards silent and efficient flight by combining bioinspired owl feather serrations with cicada wing geometry.

As natural predators, owls fly with astonishing stealth due to the serrated feather morphology that produces advantageous flow characteristics. Traditionally, these serrations are tailored for airfoil edges with simple two-dimensional patterns, limiting their effect on noise reduction while negotiating tradeoffs in aerodynamic performance. Conversely, the intricately structured wings of cicadas have evolved for effective flapping, presenting a potential blueprint for alleviating these aerodynamic limitations.

A systematic review of combinatorial treatment with warming and invigorating drugs and levothyroxine for hypothyroidism caused by Hashimoto disease.

Background: We used the systematic review method to evaluate the clinical efficacy and safety of combinatorial treatment with warming and invigorating drugs and levothyroxine on hypothyroidism caused by Hashimoto thyroiditis (HT).

Methods: We set inclusion and exclusion criteria, searched for studies using electronic databases and manual retrieval, selected studies according to the inclusion and exclusion criteria, and assessed the qualities of the included studies according to the Jadad scale. We performed a meta-analysis and analyzed the biases and sensitivities of the results using Revman 5.

[Treatment of type 2 diabetes mellitus patients of qi-yin deficiency phlegm-stasis inter-obstruction syndrome by jiangtang xiaozhi capsule and pioglitazone tablet: a non-inferiority randomized controlled trial].

Unlabelled: OBJECTIVE; To evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) of qi-yin deficiency phlegm-stasis inter-obstruction syndrome (QYDPSIOS), and to observe its effect on inflammatory factors and fibrinolytic factors.

Methods: By adopting a randomization grouping, parallel control, and prospective study, 73 T2DM patients of QYDPSIOS were assigned to two groups by random digit table, the Pioglitazone Tablet group (36 cases, as the control) and the JTXZC group (37 cases). All patients maintained their basic therapies and lifestyle as previous after recruitment.

[Clinical study of Jiangtang Xiaozhi Capsule in treating type 2 diabetes mellitus patients].

Objective: To evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) patients of qi-yin deficiency and inter-obstruction between phlegm and stasis.

Methods: Adopting prospective, randomized, controlled trial design, 73 T2DM patients of qi-yin deficiency and inter-obstruction between phlegm and stasis syndrome, were randomly assigned to two groups, the pioglitazone tablet group (36 cases) and the JTXZC group (37 cases). The therapeutic course for all was 8 weeks.
