This study aimed to compare serum cystatin C (CysC) levels between hypertensive and non-hypertensive patients, and to explore the correlation between serum CysC and left ventricular hypertrophy (LVH). We also investigated the effects of pressure overload on cardiac expression and secretion of CysC, and explored the direct effect of CysC on the hypertrophy of primary cardiomyocytes.

Serum CysC was compared in patients with hypertension (634 patients) and those without hypertension (411 patients), and the correlation between serum CysC levels and LVH was explored. A transverse aortic constriction (TAC) mouse model and a mechanical stretch model of primary cardiomyocytes and fibroblasts were developed to compare cardiac expression and secretion of CysC under pressure overload. After intervention with exogenous CysC, we compared the cross-sectional area of primary cardiomyocytes, cardiac hypertrophy-associated gene expression, and phosphorylation of the MAPK signaling pathway.

In chronic kidney disease (CKD of the MAPK signaling pathways.
Serum CysC levels were higher in hypertensive patients, and serum CysC elevation was an independent predictor of LVH after correction for eCCr. Pressure overload induced greater cardiomyocyte secretion of CysC. Exogenous CysC can enter cardiomyocytes, having a pro-hypertrophic effect on primary cardiomyocytes through regulation of the MAPK signaling pathways.
Oral squamous cell carcinoma (OSCC) is a highly heterogeneous neoplasm where the identification of heterogeneity is a critical clinical need to improve treatment planning and prognosis prediction. Utilizing the Hyperion imaging system to carry out high-dimensional proteomics analysis on the heterogeneity of tumor samples, this study aims to detect and analyze the heterogeneity of OSCC without lymph node metastasis and explore potential contributing factors for poor prognosis of early-stage OSCC.

We collected tumor tissue samples from four OSCC patients at the T1N0M0 stage, who presented with similar clinical manifestations. Patient formalin-fixed, paraffin-embedded (FFPE) tissue sections were prepared and stained using a panel of 26 immune or tumor-related antibodies. Different metal tags were assigned to each antibody. The stained cells were then detected and analyzed by the Hyperion imaging system.

Tumor samples of four OSCC patients presenting with similar clinical characteristics at the T1N0M0 stage had different cell subtypes, including CD4
T cells, CD8
T cells, CD19
B cells, CD11c
dendritic cells, CD56
natural killer cells, granulocytes, etc. More immunosuppressive cells were found in the sample of patient 1. We propose that differences in the tumor microenvironment of samples may contribute to different patients' prognosis in the future.

High-dimensional proteomics analyses using the Hyperion imaging system help identify and analyze the tumor microenvironment heterogeneity of OSCC. Our study now presents this valuable resource and explains the potential reasons behind early OSCC patients' poor prognosis.

In this experimental study, we evaluated the use of digital 3D navigation printing in minimizing complications arising from sacroiliac screw misplacement.

A total of 13 adult pelvic specimens were studied using 3D navigation printing. Mimics software was used for preoperative planning and for obtaining sacrum median sagittal resection and long axis resection of the S1 pedicle center by 3D segmentation. The ideal screw path had its origin at the post-median part of the auricular surface of the sacroiliac joint, the midpoint at the mid-position of the lateral recess and outlet of the anterior sacral foramina; and the endpoint at the S1 sagittal resection. A sacroiliac screw fixed the pelvic specimens with the assistance of the navigation module. The distance between the start point (ilium surface) and endpoint (sacral median sagittal resection) of the screw path was measured after the pre- and postoperative 3D pelvis module was 3D-registered according to the standard precision range. The origin/endpoint qualified rates of the postoperative (n/26) and preoperative (26/26) screw paths were analyzed by the chi-square test.

No screw misplacement occurred in the screw paths of any of the 13 pelvic specimens. The mean distance between the preoperative and postoperative origin of the screw path was 1.5415±0.6806 mm, and the mean distance between the preoperative and postoperative endpoint was 2.2809±0.4855 mm. The qualified rate of origin was 23/26 when the precision grade was 2.4 mm (P>0.05, χ
=1.41), while the qualified rate of endpoint was 21/26 when the precision grade was 2.7 mm (P>0.05, χ
=3.54).

In this experimental study, using a 3D printing navigation module helped attain an accurate and safe sacroiliac screw implantation.

Knee osteoarthritis (KOA) is a disease with a high incidence in elderly patients and traditional Chinese medicine has a significant effect on the treatment of KOA. Cangxitongbi capsule (CXTB) is a traditional Chinese medicine for KOA treatment and has a remarkable curative effect. The purpose of this article is to investigate the mechanism of CXTB in protecting joint cartilage on KOA rats.

A total of 30 male Sprague-Dawley rats were randomly assigned into five groups control group; model group; low-, mid-, and high-dose CXTB groups (17.5, 35, and 70 mg/mL). KOA models were made by modified Hulth method except the control group. After pharmacological administration for 4 weeks, knee articular cartilages were observed by hematoxylin and eosin (HE) staining and evaluated by Mankin score. Western blot and reverse transcription-polymerase chain reaction (RT-PCR) were used to detect the concentration of ADAMTS-5. The peripheral blood of the rats was collected to detect content of interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) by enzyme-linked immunosorbent assay (ELISA).

The morphological structure of cartilage in the 3 CXTB groups was significantly improved compared with the model group, and the improvement positively correlated with the drug dosage (P<0.05). Compared with the model group, the expression levels of ADAMTS-5 of the 3 CXTB groups was obviously decreased (P<0.05). Furthermore, the upstream targets of ADAMTS-5, including IL-1β and TNF-α were down-regulated in the 3 CXTB groups (P<0.05).

Knee joint cartilage on KOA model rats is protected by CXTB via down-regulation of ADAMTS-5. The upstream targets of ADAMTS-5, IL-1β and TNF-α, were also down-regulated by CXTB.

Embryonic stem cell (ESC)-derived cardiomyocytes have become one of the most attractive sources of cellular therapy for minimizing heart tissue damage following myocardial infarction (MI). In this study, we investigated the differentiation of BMS-189453-induced H7 human ESCs (hESCs) and purified ESCs in the treatment of induced acute MI.

BMS-189453 was used to induce the differentiation of H7 hESCs into myocardial ESCs. We further purified ESCs cells. The expression levels of the myocardial-specific protein cardiac troponin T (cTnT) and the ventricular-specific protein Myosin Light Chain 2 (MLC-2V) were detected by western blot. Quantitative reverse transcription-polymerase chain reaction (QRT-PCR) was used to detect the expression of iroquois homeobox 4 (IRX4), an important transcription factor related to ventricular muscle development. Ultrasound, radionuclides, and Holter monitoring were used to evaluate the therapeutic effect of ESCs on acute MI induced in pigs.

Compared with untreated myocardial tiave a better treatment effect than non-purified ESCs and can reduce the incidence of ventricular arrhythmias. This study has unearthed new prospects for the clinical treatment of MI.
Lung cancer is one of the most severe cancers and the majority of patients miss the best timing for surgery when diagnosed, thus having to rely on radiotherapy, chemotherapy or target therapy. Epidermal growth factor receptor (EGFR) upregulation occurs in a large percentage of patients, who can then benefit from tyrosine kinase inhibitors (TKI). However, the EGFR mutations they carry will vary the effectiveness of TKI. Circulating tumor DNA (ctDNA) contains genetic information from cancer tissue that can be used as a liquid biopsy by non-invasive sampling. This study aimed to provide a solution for minor allele detection from ctDNA.

Our novel method, named multiplex allele-specific blocker PCR (MAB PCR), combines amplification refractory mutation system (ARMS), blocker PCR and fluorescent-labeled probes for better discrimination and higher throughput. MAB PCR was specially designed for low-quality samples such as ctDNA. STING activator A sensitive assay based on MAB PCR was developed for enriching and detecting four common
mutations. This assay was optimized and evaluated with manufactured plasmids, and validated with 34 tissue samples and 94 plasma samples.

The limit of detection of this assay was 10
copies and the detection sensitivity reached 0.1% mutant allele fraction (MAF). The results of clinical sample testing had 100% accordance with sequencing, which proved that this assay was accurate and applicable in clinical settings.

This assay could accomplish low-cost and rapid detection of 4 common
mutations sensitively and accurately, which has huge potential in clinical usage for guiding medication. Furthermore, this design could be used to detect other mutations.

LMCD1 antisense RNA 1 (LMCD1-AS1) is a certified oncogene in several tumour types. However, its role in thyroid cancer (THCA) remains unknown.

The expression level of LMCD1-AS1 in THCA cells and the normal control cell was measured by quantitative real-time polymerase chain reaction (qRT-PCR). The effects of LMCD1-AS1 knockdown on cell proliferation, migration and apoptosis were detected by colony formation assay, EdU assay, wound healing assay and TUNEL assay. Sphere formation assay was applied to assess sphere formation ability of THCA cells. Bioinformatics analysis and mechanism experiments, including ChIP assay, RIP assay and luciferase reporter assay were conducted to evaluate the downstream and upstream molecular mechanisms of LMCD-AS1.

A marked up-regulation of LMCD1-AS1 in THCA cells relative to normal control cells was found. LMCD1-AS1 silencing suppressed proliferation and migration but induced apoptosis in THCA cells. Moreover, LMCD1-AS1 knockdown reduced the sphere formation capacity of THCA cells.
