[Prediction of quality markers of Angong Niuhuang Pills based on LC-MS and pull-down with SPR chips].

Elucidating the quality markers(Q-markers) of traditional Chinese medicines is essential for understanding the mechanisms of action and promoting the rational use of traditional Chinese medicines as well as for developing traditional Chinese medicine-derived drugs. Studies have shown that surface plasmon resonance(SPR) is promising in this field. This study proposed a method based on pull-down with SPR chips to predict the Q-markers of Angong Niuhuang pills(AGNHP).

An outbreak of poisoning.

Background: The mushroom is reported to cause acute liver injury. It is found in Southern China, and has been previously associated with a high incidence of mortality.

Methods: We described a series of 10 patients with poisoning admitted to The Second Affiliated Hospital of the Chinese University of Hong Kong (Shenzhen) in April 2022.

Loss of function of CMPK2 causes mitochondria deficiency and brain calcification.

Brain calcification is a critical aging-associated pathology and can cause multifaceted neurological symptoms. Cerebral phosphate homeostasis dysregulation, blood-brain barrier defects, and immune dysregulation have been implicated as major pathological processes in familial brain calcification (FBC). Here, we analyzed two brain calcification families and identified calcification co-segregated biallelic variants in the CMPK2 gene that disrupt mitochondrial functions.

Knockdown of myorg leads to brain calcification in zebrafish.

Primary familial brain calcification (PFBC) is a neurogenetic disorder characterized by bilateral calcified deposits in the brain. We previously identified that MYORG as the first pathogenic gene for autosomal recessive PFBC, and established a Myorg-KO mouse model. However, Myorg-KO mice developed brain calcifications until nine months of age, which limits their utility as a facile PFBC model system.

T4 reduces cisplatin resistance by inhibiting AEG-1 gene expression in lung cancer cells.

Lung cancer is the most malignant form of cancer and has the highest morbidity and mortality worldwide. Due to drug resistance, the current chemotherapy for lung cancer is not effective and has poor therapeutic effects. Tripchlorolide (T4), a natural extract from the plant Tripterygium wilfordii, has powerful immunosuppressive and antitumour effects and may become a potential therapeutic agent for lung cancer.

Chinese patients with hereditary spastic paraplegias (HSPs): a protocol for a hospital-based cohort study.

Introduction: Hereditary spastic paraplegias (HSPs) are uncommon but not rare neurodegenerative diseases. More than 100 pathogenic genes and loci related to spastic paraplegia symptoms have been reported. HSPs have the same core clinical features, including progressive spasticity in the lower limbs, though HSPs are heterogeneous (eg, clinical signs, MRI features, gene mutation).

Exhausting T Cells During HIV Infection May Improve the Prognosis of Patients with COVID-19.

T-cell reduction is an important characteristic of coronavirus disease 2019 (COVID-19), and its immunopathology is a subject of debate. It may be due to the direct effect of the virus on T-cell exhaustion or indirectly due to T cells redistributing to the lungs. HIV/AIDS naturally served as a T-cell exhaustion disease model for recognizing how the immune system works in the course of COVID-19.

Turner syndrome with positive gene and non-classical congenital adrenal hyperplasia: A case report.

Background: Co-morbidity of gene turner syndrome (TS) with positive gene and non-classical congenital adrenal hyperplasia (NCAH) is extremely rare and has never been reported to date.

Case Summary: In this article, we present a 14-year-old girl who was referred to our hospital with short stature (weight of 43 kg and height of 143 cm, < -2 SD) with no secondary sexual characteristics (labia minora dysplasia). Laboratory tests indicated hypergonadotropic hypogonadism with significantly increased androstenedione and 17-hydroxyprogesterone (17-OHP) levels.

Higher Concentration of Plasma Glial Fibrillary Acidic Protein in Wilson Disease Patients with Neurological Manifestations.

Background: Wilson disease is a rare, disabling, neurological genetic disease. Biomarkers of brain damage are less well developed.

Objective: The aim of this study was to evaluate the utility of plasma glial fibrillary acidic protein as a biomarker for neurological involvement in patients with Wilson disease.

Urolithin A Prevents Focal Cerebral Ischemic Injury via Attenuating Apoptosis and Neuroinflammation in Mice.

Neuroinflammation contributes to neuronal death in cerebral ischemia. Urolithin A (UA), a gut microbial metabolite of ellagic acid, has emerged as a potential anti-inflammatory agent. However, its roles and precise mechanisms in stroke remain unknown.

Novel CAPN1 mutations extend the phenotypic heterogeneity in combined spastic paraplegia and ataxia.

Objective: Recessive mutations in the CAPN1 gene have recently been identified in spastic paraplegia 76 (SPG76), a complex hereditary spastic paraplegia (HSP) that is combined with cerebellar ataxia, resulting in an ataxia-spasticity disease spectrum. This study aims to assess the influence of CAPN1 variants on the occurrence of SPG76 and identify factors potentially contributing to phenotypic heterogeneity.

Methods: We screened a cohort of 240 unrelated HSP families for variants in CAPN1 using high-throughput sequencing analysis.

Genetic and Clinical Profile of Chinese Patients with Autosomal Dominant Spastic Paraplegia.

Background: Hereditary spastic paraplegia (HSP) refers to a group of neurodegenerative disorders characterized by bilateral weakness, spasticity, and hyperreflexia in the lower limbs. The autosomal dominant HSP (ADHSP) predominantly presents as the pure form, but the clinical profiles and causal genetic variants underlying ADHSP are complex, and many remain unknown.

Methods: A cohort of 15 Chinese HSP pedigrees (including 35 patients and their 22 relatives) were screened by multiplex ligation-dependent probe amplification (MLPA) or whole-exome sequencing (WES).

Chinese patients with adrenoleukodystrophy and Zellweger spectrum disorder presenting with hereditary spastic paraplegia.

Introduction: X-linked adrenoleukodystrophy (ALD) and Zellweger spectrum disorder (ZSD) are peroxisomal diseases characterized by accumulation of very long chain fatty acids (VLCFA) in plasma and tissues. Considering the wide variability of manifestation, patients of ALD and atypical ZSD are easily misdiagnosed as hereditary spastic paraplegia (HSP) on their clinical grounds. Here, we aimed to determine the frequency of peroxisome diseases and compare their phenotypic spectra with HSP.

Stop-gain mutations in UBAP1 cause pure autosomal-dominant spastic paraplegia.

Hereditary spastic paraplegias refer to a heterogeneous group of neurodegenerative disorders resulting from degeneration of the corticospinal tract. Clinical characterization of patients with hereditary spastic paraplegias represents progressive spasticity, exaggerated reflexes and muscular weakness. Here, to expand on the increasingly broad pools of previously unknown hereditary spastic paraplegia causative genes and subtypes, we performed whole exome sequencing for six affected and two unaffected individuals from two unrelated Chinese families with an autosomal dominant hereditary spastic paraplegia and lacking mutations in known hereditary spastic paraplegia implicated genes.

Generation of an integration-free induced pluripotent stem cell line, FJMUi001-A, from a hereditary spastic paraplegia patient carrying compound heterozygous p.P498L and p.R618W mutations in CAPN1 (SPG76).

The human iPS cell line, hiPS-SPG76 (FJMUi001-A), derived from skin fibroblasts from a 42-year-old male hereditary spastic paraplegia patient carrying compound heterozygous p.P498L (c.1493C > T) and p.

Up-regulation of Wnt7b rather than Wnt1, Wnt7a, and Wnt9a indicates poor prognosis in breast cancer.

Aberrant activation of Wnt/β-catenin signaling is one of the most frequent abnormalities in human cancer, including breast cancer. The prognostic value of Wnt ligands has never been fully characterized. In this study, we focused on four Wnt ligands, namely Wnt1, Wnt7a, Wnt7b and Wnt9a, which were commonly studied and found pivotal in Wnt/β-catenin signaling, but seldom explored for their prognostic value.

Clinical spectrum and genetic landscape for hereditary spastic paraplegias in China.

Background: Hereditary spastic paraplegias (HSP) is a heterogeneous group of rare neurodegenerative disorders affecting the corticospinal tracts. To date, more than 78 HSP loci have been mapped to cause HSP. However, both the clinical and mutational spectrum of Chinese patients with HSP remained unclear.

Up-regulation of the tumor promoter Glyoxalase-1 indicates poor prognosis in breast cancer.

Glyoxalase 1 (Glo1) is an enzyme that plays a role to metabolize and inactivate methylglyoxal. Previous studies also have confirmed that Glo1 is closely related with tumorigenesis, metastasis, and drug-resistant, but its prognostic value in breast cancer has never been explored. In this study, we investigated the expression of Glo1 in breast cancer cell lines and tissues using real-time PCR, western blot and immunohistochemical analysis.

Trimester-Specific Weight Gain and Midpregnancy Diastolic Blood Pressure Rebound During Normotensive Pregnancy.

The longitudinal exposure-response relationship between trimester-specific gestational weight gain (GWG) and blood pressure (BP) during pregnancy is not well understood. We retrospectively assessed 1112 uncomplicated, normotensive pregnant women whose body weight and BP were measured from 12 to 40 weeks of gestation from a hospital-based cohort. By using growth curve modeling, a J-shaped pattern dominated diastolic BP (DBP) changing dynamics, with a midpregnancy drop at 20 to 22 weeks followed by a rebound.

Collagen triple helix repeat containing-1 negatively regulated by microRNA-30c promotes cell proliferation and metastasis and indicates poor prognosis in breast cancer.

Background: Collagen triple helix repeat containing-1 (CTHRC1), which was firstly identified overexpressed in the adventitia and neointima of injured rat arteries, could inhibit collagen expression and increase cell migration. It was then found to be ubiquitously expressed in numerous cell types such as fibroblasts and smooth muscle cells, and aberrantly up-regulated in several malignant tumors. However, the functional role of CTHRC1 and its related mechanism in breast cancer still remains unclear.

Fatigue and its associated factors in liver transplant recipients in Beijing: a cross-sectional study.

Objectives: Fatigue is a highly prevalent symptom experienced by patients who underwent the liver transplantation. However, the influencing factors of fatigue are poorly understood by healthcare professionals. The aim of this study was to examine the intensity, interference, duration and prevalence of fatigue in liver transplantation recipients and to explore the influencing factors of post-transplantation fatigue.

Prehypertension During Normotensive Pregnancy and Postpartum Clustering of Cardiometabolic Risk Factors: A Prospective Cohort Study.

The nonstratification of blood pressure (BP) levels may underestimate future cardiovascular risk in pregnant women who present with BP levels in the range of prehypertension (120-139/80-89 mm Hg). We prospectively evaluated the relationship between multiple antepartum BP measurements (from 11(+0) to 13(+6) weeks' gestation to term) and the occurrence of postpartum metabolic syndrome in 507 normotensive pregnant women after a live birth. By using latent class growth modeling, we identified the following 3 distinctive diastolic BP (DBP) trajectory groups: the low-J-shaped group (34.

Development of a bead-based suspension array for the detection of pathogens in acute respiratory tract infections.

We developed a high-throughput bead-based suspension array for simultaneous detection of 20 respiratory tract pathogens in clinical specimens. Pathogen-specific genes were amplified and hybridized to probes coupled to carboxyl-encoded microspheres. Fluorescence intensities generated via the binding of phycoerythrin-conjugated streptavidin with biotin-labeled targets were measured by the Luminex 100 bead-based suspension array system.
