Epidemiologic investigation on neurological complications following neuraxial anesthesia in 2.7 million cases in Southwest China.

Neuraxial anesthesia provides effective anesthesia and analgesia for surgery, but may cause neurological complications. The rate of neurological complications in China remains unclear. This study conducted a retrospective epidemiological investigation of neurological complications following neuraxial anesthesia in Guangxi, southwest China.

Cytoplasmic Escape of Mitochondrial DNA Mediated by Mfn2 Downregulation Promotes Microglial Activation via cGas-Sting Axis in Spinal Cord Injury.

Neuroinflammation is associated with poor outcomes in patients with spinal cord injury (SCI). Recent studies have demonstrated that stimulator of interferon genes (Sting) plays a key role in inflammatory diseases. However, the role of Sting in SCI remains unclear.

Anthocyanin metabolism and its differential regulation in purple tea (Camellia sinensis).

Tea plants (Camellia sinensis) typically contain high-flavonoid phytochemicals like catechins. Recently, new tea cultivars with unique purple-colored leaves have gained attention. These purple tea cultivars are enriched with anthocyanin, which provides an interesting perspective for studying the metabolic flux of the flavonoid pathway.

Shading-Dependent Greening Process of the Leaves in the Light-Sensitive Albino Tea Plant 'Huangjinya': Possible Involvement of the Light-Harvesting Complex II Subunit of Photosystem II in the Phenotypic Characteristic.

The light-sensitive albino tea plant can produce pale-yellow shoots with high levels of amino acids which are suitable to process high-quality tea. In order to understand the mechanism of the albino phenotype formation, the changes in the physio-chemical characteristics, chloroplast ultrastructure, chlorophyll-binding proteins, and the relevant gene expression were comprehensively investigated in the leaves of the light-sensitive albino cultivar 'Huangjinya' ('HJY') during short-term shading treatment. In the content of photosynthetic pigments, the ultrastructure of the chloroplast, and parameters of the photosynthesis in the leaves of 'HJY' could be gradually normalized along with the extension of the shading time, resulting in the leaf color transformed from pale yellow to green.

Anticarcinogenic potentials of tea catechins.

Catechins are a cluster of polyphenolic bioactive components in green tea. Anticarcinogenic effects of tea catechins have been reported since the 1980s, but it has been controversial. The present paper reviews the advances in studies on the anticarcinogenic activities of tea and catechins, including epidemiological evidence and anticarcinogenic mechanism.

Management for lumbar spinal stenosis: Protocol for a network meta-analysis and systematic review.

Introduction: Lumbar spinal stenosis (LSS) is caused by structural changes of the spine, which lead to several severe symptoms, including back pain, leg pain, numbness and tingling in the legs, as well as reduced physical function. However, there is little evidence suggesting whether a patient with LSS should be treated with surgery. If surgery is recommended, which type of surgery benefits the patient most? To answer these questions, we will conduct a network meta-analysis and a systematic review to compare surgical and nonsurgical interventions in terms of efficacy as well as safety in adult patients with LSS.

SiBaoChongCao exhibited anti-fatigue activities and ameliorated cancer cachexia in mice.

SiBaoChongCao (SBCC) is a functional food product containing fermentation of belonging to the genus. SBCC at 1 and 2 g kg for 20 days exhibited anti-fatigue activities such as increasing exhaustive swimming and running time of mice and increasing the strength of muscle. The increased muscle endurance in SBCC-treated mice might be related to enhancement of muscle cell growth and differentiation and improvement of muscle response to exercise training, as shown by an increase in muscle cross-sectional area and elevation of MHC, MyoD, MyoG and PGC-1α levels.

Ginsenoside Rh2 enhances the antitumor immunological response of a melanoma mice model.

The treatment of malignant tumors following surgery is important in preventing relapse. Among all the post-surgery treatments, immunomodulators have demonstrated satisfactory effects on preventing recurrence according to recent studies. Ginsenoside is a compound isolated from panax ginseng, which is a famous traditional Chinese medicine.

miR-15a and miR-16-1 downregulate CCND1 and induce apoptosis and cell cycle arrest in osteosarcoma.

Osteosarcoma, the most common primary tumor of the bones, causes many deaths due to its rapid proliferation and drug resistance. Recent studies have shown that cyclin D1 plays a key regulatory role during cell proliferation, and non-coding microRNAs (miRNAs) act as crucial modulators of cyclin D1 (CCND1). The aim of the current study was to determine the role of miRNAs in controlling CCND1 expression and inducing cell apoptosis.

Point-of-care test of heart-type fatty acid-binding protein for the diagnosis of early acute myocardial infarction.

Aim: To investigate the efficacies of point-of-care test of heart-type fatty-acid binding protein (H-FABP) and its combinations with the conventional biomarkers in the diagnosis of early acute myocardial infarction (AMI).

Methods: 227 patients suspected of AMI were consecutively recruited in two centers. Biomarkers including H-FABP, myoglobin (MYO), creatine kinase-myocardial band (CK-MB) and cardiac troponin T (cTnT) were determined simultaneously at admission.

[Effects of cadmium on rice seed germination].

With 319 rice varieties as test objects, this paper studied the effects of cadmium on their seed germination. The results showed that after treated with 10 mg x L(-1) of Cd2+, seed germination rate was less affected, but root growth was restrained evidently. Cadmium had more serious impact on root than on sprout.

Study on the supramolecular systems of 5-(2-hydroxy phenyl)-10,15,20-tris (4-methoxy phenyl) porphyrin with cyclodextrins.

In neutral phosphate buffer solutions of pH 7.4, the inclusive complexation of 5-(2-hydroxy phenyl)-10,15,20-tris(4-methoxy phenyl) porphyrin (o-HTPP) with alpha-cyclodextrin (alpha-CD), beta-CD, heptakis (2,3,6-tri-O-methyl)-beta-CD (TM-beta-CD), SBE-beta-CD, HP-beta-CD and gamma-CD has been examined by means of UV-vis and fluorescence spectroscopy. The formation of inclusion complexes has been confirmed on the base of changes of spectroscopy properties.
