[A multicenter study of neonatal stroke in Shenzhen, China].

Objectives: To investigate the incidence rate, clinical characteristics, and prognosis of neonatal stroke in Shenzhen, China.

Methods: Led by Shenzhen Children's Hospital, the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022. The incidence, clinical characteristics, treatment, and prognosis of neonatal stroke in Shenzhen were analyzed.

[Electroacupuncture at acupoints of meridians for sarcopenia: a randomized controlled trial].

Objective: To observe the clinical effect of electroacupuncture at acupoints of meridians for sarcopenia.

Methods: A total of 60 patients with sarcopenia were randomized into an observation group and a control group, 30 cases in each group. In the control group, conventional nutrition intervention for sarcopenia was adopted.

Optimizing the Microstructure and Corrosion Resistance of BDD Coating to Improve the Service Life of Ti/BDD Coated Electrode.

The short service life of the Ti/BDD coated electrode is the main reason that limits its practical use. In this paper, the effect of structural change on the service life was studied using Ti/BDD coated electrodes prepared with the arc plasma chemical vapor deposition (CVD) method. It was found that the microstructural defects and corrosion resistance of BDD coatings were the main factors affecting the electrode service life.
