Inositol requiring enzyme 1 alpha (IRE1α), a widespread transmembrane protein in mammals, is an endoplasmic reticulum stress (ER stress) receptor. Among the three signaling pathways of the unfolded protein response (UPR), the IRE1α pathway is the most conservative. And there is a growing body of evidence that the occurrence and development of tumors is closely related to the over-expression of IRE1α. Therefore, the study of the IRE1α inhibitors is of great significance to the discovery of new anti-tumor drugs and has been attracting more and more attention. In the hope of providing ideas for the research of targeting IRE1α for cancer therapy, this paper reviewed the data of representative IRE1α inhibitors, including inhibitory activity, the mechanism of action, structural characteristics, and so on.

OBJECTIVETo investigate the feasibility and effectiveness of modified Stoppa approach in treatment of bilateral pubic fractures of pelvic.

METHODSThe therapeutic effects of 16 patients with bilateral pubic fractures treated through the modified Stoppa approach from January 2010 to January 2014 were summarized and analyzed, involved 11 males and 5 females with an average age of 40.5 years old ranging from 17 to 59 years. According to Tile classification, there were 8 patients with type A, 6 with type B and 2 with type C. For 16 pelvic fractures, the modified Stoppa approach was used exclusively 11 cases, in combination with the iliac fossa approach in 4 cases, and in combination with the posterior approach in 1 case. The operation incision length, operation time , intra-operative blood loss and postoperative complications were observed. The fracture reduction and post-operative function were assessed by Matta criteria and Majeed system respectively.

RESULTSThe incision length of the modified Stoppa approach ranged from 8 to 10 cm (averaged in 9 cm). The operation time ranged from 75 to 135 minutes (averaged in 95 minutes). The intra-operative blood loss ranged from 400 to 900 ml (averaged in 600 ml). Sixteen patients were followed up from 7 to 18 months (averaged in 12.5 months). The fractures were all healed, the fracture healing time was 2.7 to 5 months (means 3.1 months). There were no infections, ectopic ossification, screw loosening, plate breakage and lateral ventral syndrome. According to Matta criteria for pubic fracture reduction, the result was excellent in 9 cases, good in 6, fair in 1. The Majeed function scores at 6 months after operation was 85.32±8.50; the result was excellent in 8 cases, good in 6 cases, fair in 2 cases.

CONCLUSIONThe modified Stoppa approach has characteristics of convenience and directness of incisions, clear operation field, easy reduction, few complications and fast recovery , it is an ideal choice in surgical treatment of bilateral pubic fractures.

Nitric oxide (NO), which is involved in the regulation of the cardiovascular system, nervous system, immune system, reproductive system, digestive system and other physiological activities, is an important biological substance with activity. Under normal physiological conditions, neuronal nitric oxide synthase (nNOS) can precisely regulate the nervous system NO production, release, diffusion and inactivation processes. But an excess of NO associates with the development of cerebral ischemia, Alzheimer's and Parkinson's psychosis nervous system diseases, while inhibition of nNOS activity can regulate the content of NO in vivo, and produce a therapeutic effect on some of the nervous system diseases. This review mainly describes the structure and regulation of nNOS and recent developments of small molecule inhibitors of nNOS.

This study investigated the effects and molecular mechanisms of genistein in improving insulin resistance induced by free fatty acids (FFAs) in HepG2 hepatocytes. A model of insulin resistance in HepG2 cells was established by adding palmitic acid (0.5 mmol/L) to the culture medium and the cells were treated by genistein. Glucose consumption of HepG2 cells was determined by glucose oxidase method. The levels of c-jun N-terminal kinase (JNK) phosphorylation, insulin receptor substrate-1 (IRS-1) Ser307 phosphorylation, JNK, IRS-1, phosphatidylinositol-3-kinase p85 (PI-3K p85) and glucose transporter 1 (GLUT1) proteins were detected by Western blotting. The results showed that after the treatment with palmitic acid for 24 h, the insulin-stimulated glucose transport in HepG2 cells was inhibited, and the glucose consumption was substantially reduced. Meanwhile, the expressions of IRS-1, PI-3K p85 protein and GLUT1 were obviously reduced, while the levels of JNK phosphorylation and IRS-1 Ser307 phosphorylation and the expression of JNK protein were significantly increased, as compared with cells of normal control. However, the aforementioned indices, which indicated the existence of insulin resistance, were reversed by genistein at 1-4 μmol/L in a dose-dependent manner. It was concluded that insulin resistance induced by FFAs in HepG2 hepatocytes could be improved by genistein. Genistein might reverse FFAs-induced insulin resistance in HepG2 cells by targeting JNK.

The effects of Cinnamon granules on pharmacokinetics of berberine in Rhizoma Coptidis granules in healthy male volunteers, and the compatibility mechanism of Jiao-Tai-Wan (JTW) composed of Rhizoma Coptidis granules and Cinnamon granules were investigated. The concentration of berberine in plasma of healthy male volunteers was determined directly by high performance liquid chromatography (HPLC) after an oral administration of Rhizoma Coptidis granules alone or combined with Cinnamon granules (JTW). The plasma concentration-time curves of berberine were plotted. The data were analyzed with Drug and Statistics (DAS) 2.0 pharmacokinetic program (Chinese Pharmacology Society) to obtain the main pharmacokinetic parameters. The results showed that the plasma concentration-time curve of berberine was described by a two-compartment model. The C(max), T(max), t(1/2) and CLz/F of berberine in Rhizoma Coptidis granules were 360.883 μg/L, 2.0 h, 3.882 h, 119.320 L·h(-1)·kg(-1) respectively, and those of berberine in JTW were 396.124 μg/L, 1.5 h, 4.727 h, 57.709 L·h(-1)·kg(-1) respectively. It was suggested that Rhizoma Coptidis granules combined with Cinnamon granules could increase the plasma concentration of berberine, promote berberine absorption and lengthen the detention time of berberine in healthy male volunteers.

Objective: To observe the effect of mFOLFOX7 protocolon advanced gastric cancer. Methods: Forty-eight patients with advanced gastric cancer were randomly divided into two groups: conventional treatment group (24 cases, surgery-adjuvant chemotherapy)and synthesized treatment group (24 cases, mFOLFOX7 neoadjuvant chemotherapy-surgery-adjuvant). The effect and toxic reaction of mFOLFOX7 on the patients with advanced gastric cancer were observed, and the R0 resection rate, complications incidence, survival rate were compared between two groups. Results: In synthesized treatment group, total effective rate was 58.3% .
