Personalized Machine Learning-Coupled Nanopillar Triboelectric Pulse Sensor for Cuffless Blood Pressure Continuous Monitoring.

A wearable system that can continuously track the fluctuation of blood pressure (BP) based on pulse signals is highly desirable for the treatments of cardiovascular diseases, yet the sensitivity, reliability, and accuracy remain challenging. Since the correlations of pulse waveforms to BP are highly individualized due to the diversity of the patients' physiological characteristics, wearable sensors based on universal designs and algorithms often fail to derive BP accurately when applied on individual patients. Herein, a wearable triboelectric pulse sensor based on a biomimetic nanopillar layer was developed and coupled with Personalized Machine Learning (ML) to provide accurate and continuous monitoring of BP.

Lumbar Endoscopic Unilateral Laminotomy With Bilateral Decompression Surgery in Severe Lumbar Stenosis Under Electrophysiological Monitoring-Focused on Full-Visualized Trephine/Osteotome.

Objective: Although endoscopic drill has the advantages in manipulation and hemostasis, whose low efficiency and blurred vision reduce the efficacy of lumbar endoscopic unilateral laminotomy with bilateral decompression (LE-ULBD). The present study was designed to evaluate the safety and efficacy of full-visualized trephine/osteotome in the LE-ULBD surgery for severe lumbar stenosis.

Methods: Fifty-seven severe lumbar stenosis patients who underwent LE-ULBD between January 2020 to January 2023 were enrolled, who were divided into drill and visualized trephine groups.

Predicting diabetic kidney disease for type 2 diabetes mellitus by machine learning in the real world: a multicenter retrospective study.

Objective: Diabetic kidney disease (DKD) has been reported as a main microvascular complication of diabetes mellitus. Although renal biopsy is capable of distinguishing DKD from Non Diabetic kidney disease(NDKD), no gold standard has been validated to assess the development of DKD.This study aimed to build an auxiliary diagnosis model for type 2 Diabetic kidney disease (T2DKD) based on machine learning algorithms.

Diet composition and selection of Père David's deer in Hubei Shishou Milu National Nature Reserve, China.

Hubei Shishou Milu National Nature Reserve is an ideal place to restore the wild population of Père David's deer (). Understanding foraging ecology and diet composition is essential for assessing population development or establishing long-term effective conservation measures for endangered species. However, little is known about the diet composition of Père David's deer and its diet selection mechanism.

[Analysis of Transport Pathways and Potential Sources of Atmospheric Particulate Matter in Zigong, in South of Sichuan Province].

Atmospheric particulate matter pollution in Zigong City in southern Sichuan is quite severe. The average concentrations of PM and PM from 2015 to 2018 were (95.42±9.

Synthesis of in-plane and stacked graphene/hexagonal boron nitride heterostructures by combining with ion beam sputtering deposition and chemical vapor deposition.

Graphene/hexagonal boron nitride (h-BN) heterostructures have attracted a great deal of attention in recent years due to their unique and complementary properties for use in a wide range of potential applications. However, it still remains a challenge to synthesize large-area high quality samples by a scalable growth method. In this work, we present the synthesis of both in-plane and stacked graphene/h-BN heterostructures on Cu foils by sequentially depositing h-BN via ion beam sputtering deposition (IBSD) and graphene with chemical vapor deposition (CVD).

[Ultrastructure of the upper airway skeletal muscle in patients with obstructive sleep apnea hypopnea syndrome patients].

Objective: To observe the ultrastructure of the upper airway skeletal muscle from patients with obstructive sleep apnea hypopnea syndrome (OSAHS) .

Methods: Sixteen OSAHS patients were recruited during Oct 2010 to Oct 2011. Ten patients with chronic tonsillitis were recruited as the control.

Sphincter of Oddi hypomotility and its relationship with duodenal-biliary reflux, plasma motilin and serum gastrin.

Aim: To detect whether patients with a T tube after cholecystectomy and choledochotomy have duodenal-biliary reflux by measuring the radioactivity of Tc99m-labeled diethylene triamine penta-acetic acid (DTPA) in the bile and whether the patients with duodenal-biliary reflux have sphincter of Oddi hypomotility, by measuring the level of plasma and serum gastrin of the patients. Finally to if there is close relationship among sphincter of Oddi hypomotility, duodenal-biliary reflux and gastrointestinal peptides.

Methods: Forty-five patients with a T tube after cholecystectomy and choledochotomy were divided into reflux group and control group.

Relationship between intraduodenal peri-ampullary diverticulum and biliary disease in 178 patients undergoing ERCP.

Background: The presence of intraduodenal peri-ampullary diverticulum is often observed during upper digestive tract barium meal studies and endoscopic retrograde cholangiopancreatography (ERCP). A few papers in China and overseas reported that the diverticulum had something to do with the incidence of cholelithiasis. This study was undertaken to further test this notion and ascertain the relationship between intraduodenal peri-ampullary diverticulum and biliary disease, especially the formation of bile duct pigment stones.

[The relationship between Oddi's sphincter and bile duct pigment gallstone].

Objective: To investigate the relationship between anatomic abnormalities and malfunction of Oddi sphincter with formation of bile duct pigment gallstone.

Methods: One hundred and twenty-three patients with a T tube after cholecystectomy and choledochotomy were divided into reflux group and control group by measuring the amounts of radioactivity of (99m)Tc-DTPA in the bile. Among them 53 were selected randomly to undergo choledochoscopic manometry.
