To evaluate the efficacy of Liangxue Guyuan decoction ( LGD) on radiation-induced intestinal injury in rats, and the possible underlying mechanism of action.

A total of 255 male Sprague-Dawley rats were used. 15 rats were assigned to the control group and the remaining 240 rats were exposed to a 60Co source at a dose of 11 Gy. Irradiated rats were randomly divided into model, dexamethasone (DXM), low-dose LGD (LGDl), and high-dose LGD (LGDh) groups and treated for 11 d. The survival rate, weight of body, intestinal pathology and the expression of toll-like receptor 4 (TLR4), myeloid differentiation primary response 88 (MyD88), and nuclear factor-kappa B (NF-κB) were recorded.

Radiation reduced the survival rate and weight of rats, destroyed the intestinal structure, induced an inflammatory reaction, and increased both protein and mRNA expression of TLR4, MyD88, and NF-κB in ileum. However, LGDh increased the survival rate, inhibited weight loss, alleviated inflammation and improve the expression of TLR4 pathway.

LGD increased the survival rate and inhibit weight loss of irradiated rats, and reduced inflammation and intestinal injury. The underlying mechanism may involve regulation of the TLR4/MyD88/NF-κB pathway.

To investigate the efficacy of the Danlou Fang (DL) Traditional Chinese Medicine formula on microvascular obstruction (no-reflow) through the endothelial/inducible nitric oxide synthase (eNOS/iNOS) pathway in a rat model.

Sprague-Dawley rats were subjected to 60 min of coronary artery occlusion (or sham procedure) followed by 2 h of reperfusion and were then divided into treatment groups sham, model, DL (500 mg/kg), DL (500 mg/kg) + eNOS inhibitor L-nitroarginine (L-NNA; 7.5 mg/kg), and sodium nitroprusside (SNP; 0.5 mg/kg). There were 16 per group. Areas of no-reflow were determined by thioflavin S staining of heart tissue. Cardiac function was assessed by echocardiography. Myocardial enzymes and antioxidants in serum were measured and analyzed. The relative protein expression levels of eNOS and iNOS were determined by western blotting.

DL had a myocardial protective effect on myocardial reperfusion and reduced the area of no-reflow. The serum levels of creatine kinase (CK), myocardial CK isoenzyme CK-MB, and lactate dehydrogenase were significantly lower in the DL group than in the model (P < 0.05). DL treatment also decreased the serum content of malondialdehyde and reactive oxygen species (ROS), increased the activity of superoxide dismutase and nitric oxide, and promoted eNOS expression (P < 0.05) while lowering iNOS expression.

DL reduced the area of no-reflow and had a myocardial protective effect that may be associated with the eNOS/iNOS pathway.

To explore the effects of Qingguang'an () containing serum on the expression levels of autophagy related genes in the transforming growth factor beta 1 (TGF-β1)-activated human Tenon's fibroblasts (HTFs).

(a) Primary HTFs were stimulated by TGF-β1 and underwent immunohistochemistry, which established a cell model after Glaucoma filtration surgery (GFS). (b) The cell models were divided into 4 group normal group (normal cells), model group (+TGF-β1),treatment group (+TGF-β1+ medicated serum), and positive control group (TGF-β1+ rapamycin). Then, Qingguang'an medicated serum with optimum concentration was added to the corresponding group. The autophagy positive cells were identified by the Cyto-ID autophagy detection kits under fluorescent microscope and Cytation 5 multifunctional instrument for cell imaging. And the mean fluorescence intensity of autophagy positive cells was determined by flow cytometry. The expression levels of autophagy related genes － Beclin-1, autophagy related gene 5 (ATG-5), and micrgenes (Beclin1, ATG5, and LC3Ⅱ in the TGF-β1-activated HTFs.

To evaluate the efficacy of Liuwei Dihuang formula ( LWDHF) on endothelial cells, and to study the mechanism behind the action of modulating expression of estrogen receptors.

Hydrogen peroxide (H2O2) was applied to induce the apoptosis of human umbilical vein endothelial cells (HUVECs). The concentration of nitric oxide (NO), endothelial nitric oxide synthase (eNOS) and inducible NOS (iNOS) were measured by assay kits. Western blot and real-time polymerase chain reaction (RT-PCR) were used to detect the expression of iNOS, eNOS, b-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), estrogen receptor (ER) α and ERβ. Also, small interfering RNA (siRNA) was involved to confirm whether the protective effects of LWDHF was medicated by ERs. In vivo, the female rats were ovariectomized to establish postmenopausal vascular injury model. Then the model rats were divided into three groups and treated with saline, estradiol and LWDHF respectively. The concentration of NO and NOS in serum were measured by assay kits, and the expression of Bax, Bcl-2, ERα and ERβ were detected by western blot and immunohistochemistry.

In vitro study, LWDHF significantly protected HUVECs from H2O2-induced apoptosis, with the increase of Bcl-2 and the decrease of Bax. The treatment with LWDHF inhibited concentration of NO and iNOS, and upregulated the expression of eNOS, ERα and ERβ. In addition, ERα siRNA could block the protective effects of LWDHF, while ERβ siRNA showed little influence. In vivo, the treatment with LWDHF suppressed the vascular injury and reduced the level of NO and NOS. LWDHF increased the expression of Bcl-2, ERα and ERβ, as well as inhibiting the Bax expression.

LWDHF could improve endothelial function and protect HUVECs from apoptosis via increasing the expression of ERα.

To investigate the possible antinociceptive effects of Salvia (S.) miltiorrhiza Bunge and its single components in monosodium urate (MSU)-induced pain model in mice and lipopolysaccharide (LPS)-induced inflammation model in RAW264.7 cells.

Pretreatment of S. miltiorrhiza Bunge extract (from 1 to 50 μg/mL) concentration-dependently attenuated LPS-induced nitric oxide (NO) release. The extract of S. miltiorrhiza Bunge (50 or 100 mg/kg) also caused reversals of decreased threshold for pain in the MSU-treated group as measured by Von-Frey test. Furthermore, we assessed the antinociceptive and anti-inflammatory properties of the active single components from S. miltiorrhiza Bunge such as 15, 16-dihydrotanshinone Ⅰ tanshinone Ⅱ cryptotanshinone, miltirone, tanshinone ⅡA, and salvianolic acid B. Some of them showed an anti-inflammatory effect in LPS-induced NO release model and an antinociceptive effect in MSU-treated pain model.

Our results suggest that S. miltiorrhiza Bunge extract may exert anti-inflammatory effect by reducing LPS-induced NO release and an antinociceptive property in MSU-treated pain model. Especially, tanshinoneⅡA, miltirone, cryptotanshinone, and 15,16-dihydrotanshinone Ⅰ not only appear to be responsible for LPS-induced NO release induced by S. check details miltiorrhiza Bunge, but also in the production of S. miltiorrhiza Bunge extract-induced antinociception in MSU-treated pain model.

Therefore, the analgesic and anti-inflammatory property of S. miltiorrhiza Bunge indicate it as a therapeutic potential candidate for the treatment of pain and inflammation.

To investigate the protective effects of Naoxintong capsules ( NXT)on tumor necrosis factor-α (TNF-α) -induced senescence inendothelial cells and its mechanism.

Human umbilical vascular endothelial cells (HUVECs) were treated with TNF-α ± NXT and assessed for silent information regulator 1 (SIRT1) expression and signaling. Cells were stained with beta-galactosidase to assess the levels of cellular senescence. SIRT1 was silenced through siRNA transfection.

TNF-α treatment led to the downregulation of SIRT1, resulting in forkhead box O1 (FoxO-1) acetylation, p53 acetylation and enhanced p21 expression. Following TNF-α treatment, higher SA β-Gal activity improved. TNF-α enhanced the migration of HUVECs and increased SIRT1 expression, both of which were attenuated by NXT treatment. The downstream targets of SIRT1 including FoxO-1/p53/p21 were also modulated, and HUVECs were protected from TNF-α-induced senescence. In contrast, the NXT-mediated protection was prevented by SIRT1 silencing.

These findings suggest that sustained endothelial senescence can be induced by TNF-α stimulation via the SIRT1/FoxO-1/p53/p21 pathway. The protection of NXT against TNF- was partially mediated through its effects on SIRT1. This highlights the promise of NXT as a therapeutic for atherosclerosis.

To investigate whether Zichong granules (, ZCKL), a very effective herbal formula for treating infertility, have an impact on the differentiation of ovarian granulosa cells from human embryonic stem cells (hESCs) in vitro, and to explore the cellular mechanisms of its clinical effects.

Serum from ZCKL-medicated rats was prepared and used to treat mesoderm cells derived from hESCs for 6 d. Normal rat serum and a set of growth factors were used as negative and positive controls, respectively.

ZCKL-medicated rat serum, but not normal rat serum, induced hESCs-derived mesoderm cells to differentiate into functional ovarian granulosa-like cells (OGLCs) in a similar manner to defined growth factors. The induced OGLCs resembled the morphology of native human granulosa cells, expressed granulosa cell-specific markers at both the mRNA and protein levels, produced high levels of estradiol and strongly responded to follicle-stimulating hormone stimulation. Furthermore, mRNA levels of follistatin, mothers against decapentaplegic homolog 8 and bone morphogenetic protein 6 were dynamically changed during the process.
