Prediction of testicular histology in azoospermia patients through deep learning-enabled two-dimensional grayscale ultrasound.

Testicular histology based on testicular biopsy is an important factor for determining appropriate testicular sperm extraction surgery and predicting sperm retrieval outcomes in patients with azoospermia. Therefore, we developed a deep learning (DL) model to establish the associations between testicular grayscale ultrasound images and testicular histology. We retrospectively included two-dimensional testicular grayscale ultrasound from patients with azoospermia (353 men with 4357 images between July 2017 and December 2021 in The First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China) to develop a DL model.

Enhancing osteogenic differentiation of MC3T3-E1 cells during inflammation using UPPE/β-TCP/TTC composites the Wnt/β-catenin pathway.

Periodontitis can lead to defects in the alveolar bone, thus increasing the demand for dependable biomaterials to repair these defects. This study aims to examine the pro-osteogenic and anti-bacterial properties of UPPE/β-TCP/TTC composites (composed of unsaturated polyphosphoester [UPPE], β-tricalcium phosphate [β-TCP], and tetracycline [TTC]) under an inflammatory condition. The morphology of MC3T3-E1 cells on the composite was examined using scanning electron microscopy.

Lab indicators standardization method for the regional healthcare platform: a case study on heart failure.

Background: Laboratory indicator test results in electronic health records have been applied to many clinical big data analysis. However, it is quite common that the same laboratory examination item (i.e.

Design and construction of a novel instrument for high-frequency micro-force electrical sliding friction testing.

Sliding electrical contact exists in various electrical equipment. However, its performance is significantly affected by the sliding condition such as the load, electricity, and the surface state of friction pairs. In this study, a novel instrument is designed and constructed for high-frequency microforce electrical sliding friction testing.

Eye Acupuncture Treatment for Stroke: A Systematic Review and Meta-Analysis.

There were applications of eye acupuncture for stroke patients. Unfortunately, similar to many other Traditional Chinese Medicine (TCM) treatments, it lacks comprehensive evaluation and system review for its effect and safety. Objective.

[Effects of acupuncture on distribution taxis of paclitaxel in mice with lung cancer].

Objective: To observe the effects of acupuncture at "Feishu" (BL 13) and "Lingtai" (GV 10) on distribution taxis of paclitaxel in mice with lung cancer to discuss targeted relationship between acupoints and corresponding viscera.

Methods: According to randomized digital table, 315 SPF-grade BALB/C female mice were divided into 7 groups: blank group (group A), model group (group B), medication group (group C), acupuncture at non-acupoint group (group D), acupuncture at Feishu group (group E), acupuncture at Lingtai group (group F) and acupuncture at Feishu and Lingtai group (group G), 45 mice in each one. Except the blank group, the remaining groups were treated with N-nitroso-tris-chloroethyl urea (NTCU) to establish the model of squamous-cell carcinoma.

Three-dimensional localization of impacted canines and root resorption assessment using cone beam computed tomography.

The purpose of this study was to develop a new way to localize the impacted canines from three dimensions and to investigate the root resorption of the adjacent teeth by using cone beam computed tomography (CBCT). Forty-six patients undergoing orthodontic treatments and having impacted canines in Tongji Hospital were examined. The images of CBCT scans were obtained from KaVo 3D exam vision.

Effects of acupuncture on the tissue distribution of Paclitaxel in lung carcinoma mice.

Objective: To study whether acupuncture affects the tissue distribution of Paclitaxel in mouse lung carcinoma.

Methods: Totally 90 mice were divided into Paclitaxel group, Paclitaxel + Feishu (BL13) group, and Paclitaxel + Lingtai (DU10) group. Each group was consisted of 30 mice.

[Characteristics of soil microbial community under different vegetation types in Wuyishan National Nature Reserve, East China].

By using Biolog Ecoplate system, this paper studied the structure and functional diversity of soil microbial community under different vegetation types in Wuyishan National Nature Reserve, aimed to probe into the effects of vegetation type on the diversity of soil microbial community. The results showed that the soil chemical properties, soil enzyme activities, and average well color development (AWCD) were higher in natural forest than in planted forest, and were the lowest in abandoned field. The AWCD reflecting soil microbial activity and functional diversity was increased with increasing incubation time, but there existed significant differences among different vegetation types.

Different Surface Electromyography of Propagated Sensation along Meridians Produced by Acupuncturing Quchi Acupoint (LI11) or Control Points.

This study investigated the propagated sensation along meridians (PSM) produced respectively by acupuncture at a specific acupoint of right-side Quchi (LI11), a nonacupoint on meridian (control meridian point), and neither meridian nor acupoint (control point). All the stimulated points were on the right brachioradialis along the large intestine meridian of hand Yangming. Surface electromyography (sEMG) was used to reflect the activity of the brachioradialis along the large intestine meridian of hand Yangming.

[Application of associated symptom and sign-based acupoint selection in acupuncture-moxibustion treatment].

Based on traditional acupuncture-moxibustion treatment ideas, with differentiation of channels and collaterals as main part and feature, the important role of associated symptom and sign-based acupoint selection in acupuncture-moxibustion treatment is explained from angles of philosophy and medicine. Combined with clinical experience of acupuncture and moxibustion, the category of associated symptom and sign-based acupoint selection is explained in detail to make sure the accuracy of acupuncture-moxibustion differentiation. It could show uniqueness and advantage of theory and clinic in acupuncture-moxibustion and provide theoretical references in making acupuncture-moxibustion prescription to improve effectiveness of clinical treatment.

Effects of acupuncture at Taixi acupoint (KI3) on kidney proteome.

This research explored and identified the protein composition of rat kidneys after acupuncture at the Taixi acupoint (KI3). Twelve adult male Wistar rats were randomly divided into a control group (n = 6) and an acupuncture group (n = 6). Rats in the acupuncture group received electroacupuncture on the bilateral KI3 for seven days.

[Microtensile bond strength and morphological evaluations of total-etch and self-etch adhesives to caries-affected dentin].

Objective: To evaluate the microtensile bond strength and bond interface of total-etch or self-etch adhesives to normal dentin and caries-affected dentin.

Methods: A total of 20 molars with occlusal caries lesion were used. The caries-affected dentin was obtained by removing the caries-infected dentin under the guidance of the caries detector.

Effects of residual water on microtensile bond strength of one-bottle dentin adhesive systems with different solvent bases.

Background: The wet-bonding technique is recommended for the one-bottle dentin adhesive systems, but the moisture concept varies widely among the instructions of manufacturers as well as among investigators. The aim of this study was to evaluate the effects of different dentin surface moisture on the microtensile bond strength(s) of an ethanol/water-based adhesive system and an acetone-based system to dentin.

Methods: Forty intact human premolars extracted for orthodontic reasons were used.

[Microtensile bond strengths of three dentin adhesive systems].

Objective: To evaluate in vitro the microtensile bond strengths of three dentin adhesive systems and their respective fracture modes.

Methods: A total of 15 intact young human premolars extracted for orthodontic reasons were used. The enamel of occlusal surfaces of these premolar teeth was removed and superficial dentine was exposed, finished with wet 600-grit silicon carbide paper.
