High-Throughput Preparation and High-Throughput Detection of Polymer-Dispersed Liquid Crystals Based on Ink-Jet Printing and Grayscale Value Analysis.

In this paper, based on high-throughput technology, polymer dispersed liquid crystals (PDLC) composed of pentaerythritol tetra (2-mercaptoacetic acid) (PETMP), trimethylolpropane triacrylate (TMPTA), and polyethylene glycol diacrylate (PEGD 600) were investigated in detail. A total of 125 PDLC samples with different ratios were quickly prepared using ink-jet printing. Based on the method of machine vision to identify the grayscale level of samples, as far as we know, it is the first time to realize high-throughput detection of the electro-optical performance of PDLC samples, which can quickly screen out the lowest saturation voltage of batch samples.

High-Throughput Preparation and Machine Learning Screening of a Blue-Phase Liquid Crystal Based on Inkjet Printing.

Blue-phase liquid crystal (BPLC) is considered as the next-generation liquid crystal display material, but its practical application is seriously affected by a narrow temperature range and a long research period. In this paper, we used inkjet printing technology to prepare BPLC materials with high throughput, and try to use machine vision technology to test BPLC with high throughput. The "standard curve method" for establishing each printing channel and the "vector matching method" for searching the chromaticity value of the minimum distance were proposed to improve the accuracy of inkjet printing BPLC materials.

[Treatment of severe acromioclavicular joint dislocation with double strand titanium cable and clavicular hook plate guided by self-made guide device].

Objective: To compare the clinical efficacy of titanium cable biomimetic reconstruction of coracoclavicular ligament and clavicular hook plate in the treatment of acromioclavicular joint dislocation.

Methods: The clinical data of 39 patients with severe acute acromioclavicular joint dislocation from January 2017 to December 2018 were retrospectively analyzed, 19 patients in double strand titanium cable group, including 13 males and 6 females, aged from 26 to 67 years old; Rockwood classification:10 cases of type Ⅲ, 4 cases of type Ⅳ and 5 cases of type Ⅴ;8 cases of traffic injury and 11 cases of fall injury;the time from injury to operation was 3 to 6 days. There were 20 patients in steel plate group, including 15 males and 5 females, aged from 25 to 71 years old.

Claudin-4 is required for vasculogenic mimicry formation in human breast cancer cells.

Vasculogenic mimicry (VM) refers to the unique capability of aggressive tumor cells to mimic the pattern of embryonic vasculogenic networks. Claudins are aberrantly expressed in aggressive breast cancer. However, the relationship between claudins and VM formation is not clear.

[Clinical observation on influence of vertebral fixation through or across the affected vertebra on vertebral morphology].

Objective: To compare the long-term influence of vertebral fixation through or across the affected vertebra on vertebral morphology.

Methods: Clinical data of 48 patients with simple thoracic and lumbar spinal fractures who were admitted between Jan. 2008 and Dec.

Application of trichloroacetic acid-acetone precipitation method for protein extraction in bone tissue.

Objective: To explore the feasibility and efficiency of extracting protein from bone tissue using trichloroacetic acid (TCA)-acetone precipitation method.

Methods: Hydrochloric acid (HCL) decalcification method and TCA-acetone precipitation method were separately used for bone protein extraction. The efficiencies of these two methods were compared.

[Misunderstanding about the tension band principle in the treatment of patella fractures].

Kirschner's wire tension band was the first choice in the treatment of patella fracture. But the principle of tension band had been misunderstood for long time. In the traditional principle, it was believed that tension band could change the separating force between fracture fragments into compressing stress when exercising.
