To evaluate the effects of moxibustion and acupuncture of Zusanli (ST 36) and Zhongwan (CV 12) acupoints on chronic atrophic gastritis (CAG) in rats, and to study the mechanisms behind their actions.
Forty-four male Sprague-Dawley rats were induced with CAG by intragastric administration of 40% ethanol combined with free drinking of N-methyl-N'nitro-N-nitrosoguanidine and irregular feeding for 12 weeks, followed by daily treatment with moxibustion or acupuncture for 2 weeks. Histopathologic examination, Western blotting of cytokines [epidermal growth factor (EGF), EGF receptor (EGFR), extracellular signal-regulated kinase (ERK), phosphorylated ERK (p-ERK)], and 1H NMR-based metabolic profiling of gastric tissues were used to measure changes related to CAG modeling and treatment.
Moxibustion and acupuncture at Zusanli (ST 36) and Zhongwan (CV 12) each relieved CAG-induced abnormalities in histopathology and cytokine expression of ERK and p-ERK. Only moxibustion treatment regulated the expression of EGF and EGFR. Metabolites that were increased in gastric tissue by CAG induction (alanine, nicotinamide adenine dinucleotide phosphate, uracil DNA glycosylase, lactate, glycerol and adenosine) were restored to normal levels after moxibustion treatment; acupuncture treatment only normalized the levels of adenosine monophosphate and glycerol.
Our findings suggest that moxibustion or acupuncture at Zusanli (ST 36) and Zhongwan (CV 12) can significantly improve the condition of CAG in rats. These treatments exert their effects on CAG through different mechanisms.

To detect antioxidant and antiinflammatory efficacy of Curcumin (Cur) on lung tissue in rats with sepsis.
Totally 32 rats were divided into 4 groups; the rats in Group 1 (control group) had abdominal incision under sterile conditions following anesthesia and the abdomen was sutured. Abdominal incision was performed in the rats in Group 2 (Cur group) under sterile conditions following anesthesia and the abdomen was closed. Cur was given to this group after dissolving within dimethylsulphoxide as 100 mg/kg through oral gavage and started for 3 d before surgical procedure. Group 3 (CLP group) had caecal ligation and punction (CLP) under sterile conditions to create sepsis following anesthesia and the abdomen was sutured. CLP was performed in the rats in Group 4 (CLP + Cur group) under sterile conditions following anesthesia to create a sepsis model and the abdomen was closed. Cur was also given to this group after dissolving within dimethylsulphoxide as 100 mg/kg through oral gavage and started for 3 d beforng the free radical level and increasing the antioxidant enzyme levels; and an antiinflammatory effect by reducing iNOS level.
The study outcomes revealed that supplementation of Cur presents an antioxidant effect by reducing the free radical level and increasing the antioxidant enzyme levels; and an antiinflammatory effect by reducing iNOS level.
To investigate effect of electroacupuncture (EA) with Bushen Jiannao on learning and memory ability in senescence-accelerated mouse prone 8 (SAMP8) mice and the related mechanisms.
8-month-old senescence-accelerated-resistant (SAMR1) and SAMP8 mice were treated with EA at Baihui (GV 20), Shenshu (BL 23), and Taixi (KI 3) acupoint once a week for 8 weeks. The Morris water maze, enzyme linked immunosorbent assay, immunohistochemistry, and Western blot were used to assess Alzheimer's disease (AD)-associated cognitive and neuroinflammatory phenotypes.
Our data showed that EA treatment decreased activation of microglia and astrocytes, decreased levels of inflammatory factors including tumor necrosis factor-α (TNF-α), interleukin (IL)-6, and IL-17, and improved spatial memory deficits in SAMP8 mice. EA therapy with Bushen Jiannao exhibited anti-inflammatory properties and improved cognitive function.
The present study indicates that EA treatment based on the interaction between kidney and brain can improve learning and memory ability by inhibiting activation of astrocytes and microglia and decreasing expression of pro-inflammatory cytokines, TNF-α and IL-17. EA treatment based on the interaction between kidney and brain may be an effective treatment for AD.

To investigate synergistic effect of Reduning (RDN) injection plus ribavirin against severe pneumonia induced by H1N1 influenza A virus in mice.
We established a mouse model of severe pneumonia induced by influenza A virus by infecting Balb/c mice with CA07 virus. We randomly assigned the infected mice into four groups, and treated them with normal saline (NS group), RDN (injection, 86.6 mg/kg), ribavirin (injection, 66.6 mg/kg) or double Ribavirin plus RDN group, the same dosage as used in the single treatments) for 5 d. Lung index and lung pathology were recorded or calculated in terms of the curative effective. Cytokines, NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome related protein including caspase-associated recruitment domain (CARD) domain Apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC), caspase-1 and NOD-like receptor family, pyrin domain containing 3 (NLRP3), and reactive oxygen species were simultaneously investigated.
RDN plus ribirin could protect the mice, and reduce the lung immunopathologic damage caused by severe influenza pneumonia. The mechanism could be that it reduced ROS produce and inhibited NLRP3 inflammasome activation so that mainly lower the downstream inflammatory cytokines IL-1β and IL-18.
To investigate the efficacy of active compounds of Chanqin (CQ) granules on PM2.5-induced airway neurogenic inflammation in vivo, and to elucidate the underlying mechanisms of action.
The Traditional Chinese Medicine systems pharmacology (TCMSP) database was searched, and the results were combined with oral bioavailability and drug analysis to identify the compounds in CQ granules. Lotiglipron supplier The pharmacophore modeling approach was used to predict the compound targets, and the diseases corresponding to the targets were obtained by searching the therapeutic target database (TTD), pharmacogenomics knowledgebase (PharmGKB) and DrugBank databases. Cytoscape software was used to construct the network pharmacological charts for Component-Target and Target-Disease interactions of the CQ granules. Then, the mechanisms of action and effectiveness of CQ granules for the treatment of PM2.5-induced airway neurogenic inflammation were analyzed.
A total of 195 compounds and 171 targets were obtained from the analyses. A total of 569 corresponding diseases were identified for these targets.
