[Research progress on active ingredients of animal-derived traditional Chinese medicine in treatment of allergic rhinitis].

Allergic rhinitis(AR) is a common chronic inflammatory disease of the upper respiratory tract. Due to its high prevalence, high recurrence rate, and lack of a definitive cure, it is considered a global health issue by the World Health Organization. The pathogenesis of AR is complex and mainly involves B cells, helper T cells, eosinophils, basophils, macrophages, as well as the cytokines and inflammatory mediators they secrete.

MiR-181a-5p facilitates proliferation, invasion, and glycolysis of breast cancer through NDRG2-mediated activation of PTEN/AKT pathway.

Dysregulation of microRNAs (miRNAs) is associated with the occurrence and development of breast cancer. In this research, we explored the involvement of miR-181a-5p in the progression of breast cancer and investigated potential molecular mechanisms. Firstly, the miR-181a-5p and N-myc downstream-regulated gene (NDRG) 2 expression was detected by real-time quantitative polymerase chain reaction.

A protective effect of baicalin on cerebral ischemic rats is related to the improvement of serum progesterone level in serum.

Baicalin, an ingredient drawn from Scutellaria amoena Georgi, plays a brain-protective role through anti-inflammatory, antioxidant, and other pathways. The aim of this study was to investigate the possible protective mechanism of baicalin on middle cerebral artery occlusion rats. Rats were divided into 4 groups: sham, middle cerebral artery occlusion, middle cerebral artery occlusion + baicalin, middle cerebral artery occlusion + baicalin treated + inhibitor (bromocriptine, which inhibit progesterone induction).

Effects of Notch Signaling Pathway in Cervical Cancer by Curcumin Mediated Photodynamic Therapy and Its Possible Mechanisms in Vitro and in Vivo.

Curcumin, as a high effect and low toxicity anti-cancer drug and photosensitiser, has synergistic and complementary effects with photodynamic therapy (PDT). However, due to its unclear mechanism, PDT's application and efficacy were limited. Notch signaling pathway, which is highly correlates with carcinogenesis and development of cervical cancer, could be a potential therapeutic targets to improve the effectiveness of PDT.

Tongluojiunao, a traditional Chinese medication with neuroprotective ability: A review of the cellular, molecular and physiological mediators of TLJN's effectiveness.

The pressing need to discover more effective drugs for various CNS disorders has resurrected the idea of investigating the effectiveness of traditional medicines in modern science. Tongluojiunao (TLJN) is an example of revived modern herbal preparation based on traditional Chinese medicine (TCM) with a long history of administration for various types of cerebrovascular injuries and neurodegenerative diseases. TLJN is prepared from the herbal roots of Panax notoginseng (Sanchi) and dried fruits of Gardenia jasminoides (Cape Jasmine), and so far, it has demonstrated promising results in patients with vascular dementia and cerebral ischemic stroke.

Synergistic neuroprotective effect of microglial‑conditioned media treated with geniposide and ginsenoside Rg1 on hypoxia injured neurons.

The synergistic mechanism underlying the effects of multi‑component combined drug use for complex diseases remains to be fully elucidated. Microglial activation following ischemia can either affect neural survival or cause neuronal injury. The aim of the present study was to determine the synergistic effect of geniposide and ginsenoside Rg1, based on microglial‑neuronal communication.

Chinese herbal formula Tongluo Jiunao injection protects against cerebral ischemia by activating neurotrophin 3/tropomyosin-related kinase C pathway.

The Chinese herbal formula Tongluo Jiunao, containing the active components Panax notoginseng and Gardenia jasminoides, has recently been patented and is in use clinically. It is known to be neuroprotective in cerebral ischemia, but the underlying pathway remains poorly understood. In the present study, we established a rat model of cerebral ischemia by occlusion of the middle cerebral artery, and administered Tongluo Jiunao, a positive control (Xuesai Tong, containing Panax notoginseng) or saline intraperitoneally to investigate the pathway involved in the action of Tongluo Jiunao injection.

[Preliminary research on multi-neurotransmitters' change regulation in 120 depression patients' brains].

In view of the effective traditional Chinese medicine (TCM) in the treatment of clinical depression, the mechanism is not clear, this study attempts to research the cause of depression in a complex situation to lay the foundation for the next step of TCM curative effect evaluation. Based on the brain wave of 120 depression patients and 40 ordinary person, the change regulation of acetylcholine, dopamine, norepinephrine, depression neurotransmitters and excited neurotransmitters in the whole and various encephalic regions' multi-neurotransmitters of depression patients-serotonin are analysed by search of encephalo-telex (SET) system, which lays the foundation for the diagnosis of depression. The result showed that: contrased with the normal person group, the mean value of the six neurotransmitters in depression patients group are: (1) in the whole encephalic region of depression patients group the dopamine fall (P < 0.

Radix Achyranthis Bidentatae improves learning and memory capabilities in ovariectomized rats.

Kidney-tonifying recipe can reduce the accumulation of advanced glycation end products, prevent neuronal degeneration and improve cognitive functions in ovariectomized rats. Radix Achyranthis Bidentatae alcohol extracts may dose-dependently inhibit non-enzymatic saccharification in vitro. This study aimed to examine the effect of Radix Achyranthis Bidentatae on advanced glycation end products and on learning and memory capabilities in ovariectomized rats.

Tong Luo Jiu Nao injection, a traditional Chinese medicinal preparation, inhibits MIP-1β expression in brain microvascular endothelial cells injured by oxygen-glucose deprivation.

Ethnopharmacological Relevance: Tong Luo Jiu Nao injection (TLJN), a modern Chinese formula based on Traditional Chinese Medicine theory, has been used to treat ischemic stroke and vascular dementia. TLJN belongs to the ethnopharmacological family of medicines.

Aim Of The Study: To investigate the protective effect of TLJN on oxygen-glucose deprivation (OGD) induced-injury of brain microvascular endothelial cells (BMECs).

Impact of paracrine signals from brain microvascular endothelial cells on microglial proliferation and migration.

Neuronal survival can be influenced by activated microglia, but limited evidence exists on the effects of paracrine signaling from brain microvascular endothelial cells (BMECs) on microglial action. Therefore, we examined the effects of normal BMECs conditioned medium (BMECs-CM) on activated microglia induced by pro-inflammatory cytokine macrophage inflammatory protein-1beta (MIP-1β), a chemokine that released from ischemic BMECs and has been proved to stimulate microglial proliferation. Our results showed that BMECs-CM inhibited the proliferation and transmigration of microglia induced by MIP-1β.

Vascular endothelial growth factor signaling implicated in neuroprotective effects of placental growth factor in an in vitro ischemic model.

Placental growth factor (PlGF) is involved in the angiopoiesis of the placental chorion and the maintenance of the placenta. Some additional roles of PlGF in other tissues have recently been described. Relatively little is known about PlGF expression in the CNS and the involvement of PlGF in cerebral ischemia injury.

Evaluation of the protective effects of Chinese herbs against biomolecule damage induced by peroxynitrite.

This work evaluates the protective effects of Chinese herbs against ONOO(-)-induced biomolecule damage. Thirty-two Chinese traditional herbs were preliminarily screened for their ONOO(-)-scavenging activity by the fluorometric method. The potency of scavenging activity was in the following order: Apis cerana Fabricius (Propolis) > Rosmarinus officinalis L (Rosemary) > Pseudolarix amabilis (Nelson) Rehd.

Simultaneous determination of geniposide, baicalin, cholic acid and hyodeoxycholic acid in rat serum for the pharmacokinetic investigations by high performance liquid chromatography-tandem mass spectrometry.

A simple, rapid, and specific analytical method for simultaneous determination of geniposide, baicalin, cholic acid and hyodeoxycholic acid in 50 microL samples of rat serum was developed by high performance liquid chromatography-tandem mass spectrometry. The quantification of the target compounds was determined by multiple reaction monitoring (MRM) mode using electrospray ionization (ESI). The correlation coefficients of the calibration curves were better than 0.
