This study aimed to explore the efficacy and safety of chloroprocaine for activating labor analgesia and the optimal concentration compared to lidocaine.

Ninety-six nulliparous parturients were randomly assigned to three groups LD group, patients received the conventional initial dose of 6 mL of 1% lidocaine; CP1.5 group, patients received 6 mL of 1.5% chloroprocaine as the initial dose; and CP1.2 group, patients received 7.5 mL of 1.2% chloroprocaine as initial dose. Labor analgesia was maintained in all patients via a programmed intermittent epidural bolus (PIEB). The primary outcome was the analgesia onset time. Secondary outcomes included the visual analog scale (VAS) scores, the interval and duration of uterine contractions during the first 12 contractions, failure to reach adequate analgesia, labor and neonatal outcomes, maternal satisfaction and adverse effects.

Parturients in the CP1.5 and CP1.2 groups achieved a shorter onset time than those in the LD group (hazard ratio (HR) = 6.540; 95% confi3).

The study was registered prior to subject enrollment at www.chictr.org.cn (ChiCTR2100049113).

To analyze the association between

gene polymorphism/expression and susceptibility/prognosis of hepatocellular carcinoma (HCC).

Peripheral venous blood from 204 hepatocellular carcinoma patients (HCC group), 242 chronic hepatitis B patients (CHB group), 215 liver cirrhosis patients (LC group) and 201 healthy volunteers (normal group) were collected.

gene (including the rs9808232 locus) was amplified by PCR and the products were sequenced. Tumor tissues from patients with HCC and liver tissues from CHB, LC and normal groups were collected, and mRNA and protein expression of

gene in liver tissues were tested by RT-qPCR and immunofluorescence, respectively.

Compared with the normal group, the mRNA and protein expression levels of

in the HCC group increased significantly (

< 0.05), but there are no obvious increases in the CHB and LC groups (

> 0.05).

gene rs9808232 polymorphism was associated with an increased susceptibility of HCC, and genotypes AC and CC may be risk factors for H susceptibility and poor prognosis of HCC.

Inclusion body myositis (IBM) is a unique idiopathic inflammatory myopathy with unclear pathogenesis and poor prognosis. Although previous publications have identified some molecular biomarkers, the value of these biomarkers is unknown.

To identify hub genes and signaling pathways related to IBM for understanding the IBM-related mechanisms and providing guidance for therapy development.

Two microarray datasets (GSE3112 and GSE128470) were downloaded from the Gene Expression Omnibus (GEO) database. GEO2R was used to detect differentially expressed genes (DEGs) between IBM and normal muscle tissues. The hub genes were determined using protein-protein interaction (PPI) network in Cytoscape. The specific signaling pathways and biological functions of IBM were identified using GO, KEGG, and GSEA enrichment analyses. Moreover, CIBERSORT was applied to estimate the expression level of 22 immune cell types in IBM and normal muscle tissue. The relationship between the immune cell types and hub genes was then explored.

A total of 219 DEGs and 10 hub genes were identified. Enrichment analyses revealed that the chemokine signaling pathway, cellular response to interferon-gamma, and P53 pathway have crucial roles in IBM. Immune infiltration analyses showed that IBM was associated with high level of CD8 T cells, Tregs, and macrophages. Finally, five potential drugs were predicted for IBM patients through CMap (connectivity map) database.

In this study, the underlying molecular mechanisms and immunological landscape of IBM were investigated, and thus may provide new directions for future research on IBM pathogenesis.

Several recent studies have shown the relationship between the triglyceride glucose (TyG) index and the risk of stroke in the general population and in a few patient cohorts; however, the role of the TyG index on stroke risk in elderly hypertensive patients has not been determined. Thus, we aimed to investigate the association of the TyG index with first stroke and first ischemic stroke in elderly individuals with hypertension.

We included 8487 elderly subjects with hypertension from the China H-type Hypertension Registry Study for the current analysis. The TyG index was calculated as ln (fasting triglyceride [mg/dL] × fasting glucose [mg/dL]/2). Outcomes were the first stroke and first ischemic stroke.

During a median follow-up of 1.72 years, the first stroke was diagnosed in 82 patients (0.97%), and the first ischemic stroke was diagnosed in 48 patients (0.57%). Multivariable Cox proportional hazards models revealed that the TyG index was positively associated with the risk of first stroke (per 1-unit increment; HR 1.72; 95% CI 1.07, 2.76) and first ischemic stroke (HR 2.31; 95% CI 1.32, 4.05). When the TyG index was assessed as quartiles, significantly higher risks of first stroke (HR 1.90; 95% CI 1.04, 3.45) and first ischemic stroke (HR 2.45; 95% CI 1.16, 5.20) were found in participants in quartile 4 compared with those in quartiles 1-3.

The TyG index is potentially useful in the early identification of elderly hypertensive patients at high risk of experiencing a first stroke.

We aimed to explore the potential association of body composition parameters measured by bioelectrical impedance analysis (BIA) with the incidence of sarcopenia in patients with acute myeloid leukemia (AML) (non-M3) after chemotherapy.

This was a single-center observational study. Sixty-nine patients with newly diagnosed AML underwent BIA at the time of initial diagnosis and after completion of three chemotherapy sessions. Pre- and post-chemotherapy BIA parameters were compared. Sarcopenia was defined as low skeletal muscle mass plus low muscle strength according to the Asian Working Group for Sarcopenia (AWGS). Association of sarcopenia with mid-arm muscle circumference (MAMC) and intracellular water (ICW) was assessed by multivariate logistic regression.

There was a significant increase in the prevalence of sarcopenia after chemotherapy (39.1% vs 14.5%,

<0.001). Skeletal muscle mass (SMM), fat-free mass (FFM), and soft lean mass (SLM) showed a significant decrease after chemotherapy (

<0.05). MAMC, ICW, and total body water (TBW) significantly decreased after chemotherapy (

<0.05). BIA indices including appendicular skeletal muscle mass (ASM) (

=0.889,

<0.001), ICW (

=0.869,

<0.001), MAMC (

=0.849,

<0.001) showed a positive correlation with SMI. Moreover, ASM (

=-0.453

=0.001), ICW (

=-0.322,

<0.05), and MAMC (

=-0.352,

<0.05) showed a negative correlation with sarcopenia. On multivariate logistic regression analysis, increased ICW was associated with decreased risk of sarcopenia [odds ratio (OR) 0.50; 95% confidence interval (CI) 0.30-0.82]. Each additional unit of MAMC after chemotherapy was associated with 71% lower risk of sarcopenia (OR 0.29; 95% CI 0.13-0.66).

The incidence of sarcopenia was associated with chemotherapy of patients with AML (non-M3) as reflected by body composition changes.

Immune cell infiltration plays a critical role in regulating peptic ulcer disease (PUD) and gastrointestinal cancer (GC). However, regulators of the cell signaling hubs remain unclear.

This study characterizes genes that are differentially expressed in PUD and GC tissue samples. Bioinformatics is used to define the immune-associated hub genes associated with the malignant transfer process of PUD to GC.

Total expression data from PUD and early-stage GC tissue samples were obtained from GEO and TCGA. Differentially expressed genes were assessed and immunological enrichment analysis was performed. Protein-protein interaction (PPI) and Cytoscape analysis were used together to identify the hub genes. CIBERSORT and COX analysis were used to analyze the differentially infiltrated immune cell landscapes and determine HR scores of the hub genes.

Expression data identified 437 DEGs as common to both GC and PUD tissue. Of these, 49 immune-related DEGs were grouped by function, and seven hub genes were identified by PPI analysis. The NRP2 and SEMA3D genes were then selected for survival analysis. SEMA3D had a higher hazard ratio than NRP2 and was defined as the hub for PUD carcinogenesis.

SEMA3D was characterized as the hub gene for PUD carcinogenesis.

SEMA3D was characterized as the hub gene for PUD carcinogenesis.

Although several studies have explored the association of sex hormones with glucose metabolism, the association between sex hormones and body fat distribution, which is closely related to insulin resistance, has not been fully elucidated. We have tried to explore the relationship of testosterone (T) and estradiol (E2) with visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) mass in Chinese men with different obese and metabolic statuses.

A total of 128 men from the Health Management Center of the Second Xiangya Hospital, Central South University were collected and grouped in accordance with their obese and metabolic syndrome (MS) statuses metabolically healthy non-overweight/obese men (MHNO), metabolically healthy overweight/obese men (MHO) and metabolically unhealthy overweight/obese men (MUO). Multiple regression analyses were performed to estimate contributions of sex hormones levels to the variations of body fat distribution and the contributions of body fat distribution to the variati10194. Retrospectively registered.

This research examined the association of cigarette smoking and altitude with the blood levels of 25-hydroxy vitamin D, testosterone and carotid artery thickness.

This comparative cross-sectional study involved 37 non-smokers and 24 smokers from a high-altitude area (≥2245 m above sea level) and 40 smokers and 40 non-smokers from a low-altitude area (39-283 m above sea level). The blood testosterone level was determined spectrophotometrically, and the 25-hydroxy vitamin D concentration was measured by ELISA. The IMT of the right and left carotid arteries was determined using ultrasound imaging.

Smoking notably elevated the thickness of the intima media of the right and left carotid arteries at both high and low altitudes (

≤ 0.001). Smoking at high altitude was associated with a significant increase in the concentration of 25-hydroxy vitamin D and testosterone, while at low altitude it was associated with a significant decrease in both parameters (

≤ 0.046).

These contrasting results suggest that future studies should focus on finding out if other biochemical parameters show any significant differences in smokers or/and non-smokers when they are tested at elevated height and sea-level. This indicates that dose modifications of medicines (related to alterations in vitamin D and testosterone levels) should be kept in mind while treating smokers and non-smokers at elevated height above sea level.
