Transcriptomic and Metabolomic Analysis Reveal Possible Molecular Mechanisms Regulating Tea Plant Growth Elicited by Chitosan Oligosaccharide.

Chitosan oligosaccharide (COS) plays an important role in the growth and development of tea plants. However, responses in tea plants trigged by COS have not been thoroughly investigated. In this study, we integrated transcriptomics and metabolomics analysis to understand the mechanisms of chitosan-induced tea quality improvement and growth promotion.

Circulating Expression Level of LncRNA Malat1 in Diabetic Kidney Disease Patients and Its Clinical Significance.

Background: Long noncoding RNA MALAT1 is closely related to diabetes and kidney diseases and is expected to be a new target for the diagnosis and treatment of diabetic nephropathy.

Objective: This study aimed to explore the circulating expression level and significance of lncRNA Malat1 in patients with type 2 diabetes mellitus (T2DM) and diabetic kidney disease (DKD).

Methods: Quantitative real-time PCR (qPCR) was conducted to assess the expression of lncRNA Malat1 in 20 T2DM patients, 27 DKD patients, and 14 healthy controls, and then, the clinical significance was analyzed.

Zerumbone Protects against Carbon Tetrachloride (CCl)-Induced Acute Liver Injury in Mice via Inhibiting Oxidative Stress and the Inflammatory Response: Involving the TLR4/NF-κB/COX-2 Pathway.

The natural compound Zerumbone (hereinafter referred to as ZER), a monocyclic sesquiterpenoid, has been reported to possess many pharmacological properties, including antioxidant and anti-inflammatory properties. This study aimed to investigate the underlying mechanism of ZER against acute liver injury (ALI) in CCl-induced mice models. ICR mice were pretreated intraperitoneally with ZER for five days, then received a CCl injection two hours after the last ZER administration and were sacrificed 24 h later.

[Effect of Gansui Banxia Tang plus-minus Gansui and Gancao anti-drug combination that preferred dose close to clinical application on diuretic effect in malignant ascites rats].

Objective: To observe the effect of Gansui Banxia Tang plus-minus Gansui and Gancao anti-drug combination on hepatic and renal functions in malignant ascites rats to explore whether the efficacy or toxicity associated with the anti-drug combination.

Method: The male wistar rats were randomly divided into a blank group, model group, furosemide group, Gansui Banxia Tang group, Gansui Banxia Tang removed Zhigancao group, Gansui Banxia Tang removed Cugansui group, Gansui Banxia Tang removed Zhigancao and Cugansui group. In addition to normal feeding, every morning except for the blank group and model group, the rest of the group was given drugs, the control group and the model group was given distilled water, the volume is 10 mL x kg(-1).

[Correlation between PTPN22 gene polymorphism and systemic lupus erythematosus in Chinese Han patients].

Objective: To investigate the association between 1858C/T single nucleotide polymorphism on exon 14 of the protein tyrosine phosphatase nonreceptor-22 (PTPN22) gene and systemic lupus erythematosus in Chinese Han patients.

Methods: Forty Chinese Han patients with SLE and 20 normal control subjects were enrolled in the study, and PTPN22 gene 1858 C/T polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

Results: No significant difference was found in the CC, CT, and TT genotype frequencies or in the C and T allele frequencies between the SLE patients and the normal controls.

GC-MS, FT-IR analysis of black fungus polysaccharides and its inhibition against skin aging in mice.

The monosaccharide compositions, molecular weights, structure were investigated for the black fungus polysaccharides. Analysis of sugar components by gas chromatograph-mass spectrometer (GC-MS) showed that component ratios of neutral sugars in the polysaccharides were Glc:Man=82.97:12.

[Effects of Guanyu capsule on the behavior and cerebral cortex monoamine neurotransmitters in depressive model of olfactory bulb damage rats].

Objective: To investigate the behavioral changes and the levels of monoamine neurotransmitters in the anterior cortex in the olfactory bulb damage rats after being treated with Guanyu capsules (GYC).

Method: Open-field test and step-down passive avoidance test were used to observe the behavior in model rats. HPLC-ECD was used to analyze the influences of GYC on the levels of monoamine neurotransmitters.

[Effects of Qilan Tangzhining capsule on glucose and lipid metabolism in rats with diabetes mellitus and hyperlipemia].

Objective: To study the effects of Qilan Tangzhining capsule on glucose and lipid metabolism in diabetes mellitus and hyperlipemia.

Method: Rats were fed with high sugar and fat food for 2 months, then 2% streptozocin (STZ, 30 mg kg(-1)) was injected intraperitoneally to induce hyperglycemia and hyperlipemia. After the model rats were administrated drugs, the blood glucose, the serum lipids, and the histopathology of the liver and pancreas were observed.
