Gut microbial metabolite trimethylamine-N-oxide (TMAO) is associated with type 2 diabetes (T2DM). Decreased insulin sensitivity is a significant etiological factor of T2DM. Adipocytes, myocytes, and hepatocytes are the three major target cells for insulin. This study aims to investigate the effects and mechanisms of TMAO on the insulin sensitivity of these target cells. Research results indicate that in different ages of db/db diabetic mice, plasma TMAO levels were increased. TMAO significantly inhibits the insulin signaling pathways in these three major insulin target cells, reduces glucose uptake in 3T3-L1 adipocytes and L6 myocytes and downregulates genes related to gluconeogenesis in primary mouse hepatocytes. Furthermore, in mice with normal insulin sensitivity, elevating plasma TMAO levels to those seen in db/db mice using a minipump results in impaired glucose tolerance and hyperinsulinemia. All animal experiments were carried out with approval of the Experimental Animal Welfare Ethics Committee of the Institute of Materia Medica (Chinese Academy of Medical Sciences and Peking Union Medical College). Mechanistic studies suggest that TMAO exposure increases the levels of endoplasmic reticulum stress-related proteins in these three major insulin target cells. In summary, TMAO directly attenuates insulin sensitivity in insulin target cells, and its mechanism of action may involve enhancing endoplasmic reticulum stress.

OBJECTIVETo investigate the effect of Busheng Huoxue Capsule (BHC) on the quality of life (QOL) in senile male osteoporosis (OP) patients, and to explore its mechanisms.

METHODSTotally 200 senile primary OP patients were randomly assigned to two groups according to random digit table method, 100 in each group. Patients in the treatment group took BHC plus caltrate-D (600 mg CaCO3), while those in the control group took alendronate (70 mg per week) plus caltrate-D. The therapeutic course was 12 months for all. Chinese medical symptom score and quality of life (QUALEFFO-41) score, bone mineral density (BMD) of lumbar vertebra (L2 -L4) and left femoral neck were compared between the two groups before and after treatment. Serum free testosterone (FT) and estradiol (E2) were also measured.

RESULTSChinese medical symptom scores and QUALEFFO-41 scores, serum FT and E2 levels increased in the two groups after treatment (P < 0.05, P < 0.01). The therapeutic effect was superior in the treatment group (P < 0.05, P < 0.01). After treatment the BMD of lumbar vertebra (L2 -L4) and the left femoral neck were somewhat improved (P < 0.05), but with no statistical difference between the two groups (P > 0.05).

CONCLUSIONBHC could effectively improve the QOL of senile male OP patients, which might be correlated with elevating the BMD levels and regulating the levels of sex hormones.

There are many progresses in the therapy of MM with ASCT. ASCT improves the ratio of CR,EFS and OS,compared with conventional chemotherapy.Myeloma patients with renal failure or old age also can be candidate for ASCT.Tandem autologous transplantation improves the ratio of CR. Its impact to long-term EFS and OS still need to be judged.To improve conditional project,to choose suitable time,and- toselect consolidation schedule can boost therapeutic effect.

This study aims to optimize the most effective component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on lung cancer A549 using the orthogonal design method, and to investigate its effects of the component formula on cell proliferation, apoptosis and cytoskeleton in lung cancer A549 cells. The orthogonal design method was introduced to optimize the most effective component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on lung cancer A549 cells. CCK-8 assay and Real-time cell analysis were adapted to analyze the effect of component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma on A549 cells viability at different time and dose. Cell apoptosis was measured by Annexin V- FITC/PI double staining and flow cytometry. Cell skeleton protein F-actin was detected by high content screening (HCS). The optimizing component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma for total salvianolic acid, total saponins of panax ginseng and ginseng polysaccharide doses were 5, 10, 5 mg L(-1). CCK-8 assay and real-time cell analysis demonstrated that the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma treatment could significantly decrease the A549 cell viability in both dose- and time-dependent manner compared with control group (P < 0.01). Moreover, the increase of cell apoptosis was detected by Annexin V-FITC/PI double staining and flow cytometry when cells treated with the component formula, which indicating that the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma could induce A549 cell apoptosis in a time-dependent manner compared with control group (P < 0.01). Furthermore, compared with control group, a significant decrease in A549 cell skeleton area was found in the component formula-exposed cells in the dose-dependent manner (P < 0.01). In summary, the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma inhibits A549 cell proliferation by inducing cell apoptosis and decreasing cell microfilament formation. All of these results will be helpful to reveal antitumor mechanism of the component formula of Salviae Miltiorrhizae Radix et Rhizoma and Ginseng Radix et Rhizoma, which provides a basis for the exploration of antitumor mechanism of the component formula on lung cancer.

BACKGROUND:Acute poisoning is frequently encountered at emergency department. This study was to investigate the epidemiology and characteristics of patients with acute poisoning who were treated at the Emergency Center, Fujian Provincial Hospital, China. METHODS:We retrospectively analyzed the gender, age, causes of poisoning, types of poisons, poisoning route, emergency diagnoses, outcomes, and prognoses of these patients. RESULTS:Altogether 2867 patients with acute poisoning were treated from January 2004 to December 2009. The ratio of male to female was 1:1.04, and their average age was 33.8 years. Of the 2867 patients, 76.39％ were between 18 and 40 years old. The incidence of acute poisoning was as high as 11.33％ in January each year. The incidence of poisoning was in a descending order:alcohol poisoning (54.55％), medication poisoning (25.95％), pesticide poisoning (5.65％), and drug poisoning (4.88％). Most (56.44％) of the patients with drug poisoning were under 25 years and their mean age was significantly lower than that of patients with medication poisoning or alcohol poisoning (P < 0.01). Approximately 69.54％ of the patients were followed up after emergency treatment, 30.39％ were hospitalized, and four patients died. CONCLUSIONS:Acute poisoning is largely alcohol poisoning and medication poisoning in a city. The emergency green channel "pre-hospital emergency care-emergency department-hospital treatment"can significantly improve the survival rate of patients with acute poisoning.

Argyrogramma agnata has been selected as a substitutive host insect for producing Dendrolimus punctatus Cytoplasmic Polyhedrosis Virus (DpCPV). In our experiment, it is very susceptible to DpCPV. The DpCPV produced in A. agnata is designated Aa-DpCPV. The cytoplasmic polyhedra body (CPB), the virion size and the shape of Aa-DpCPV are same as that of its original DpCPV (DpCPV-W1984). The RNA bands of Aa-DpCPV and DpCPV-W1984 all have 10 RNA segments respectively in 3% PAGE, which molecular weights ranged in size from 2.98×106 to 0.66×106 Dalton. Aa-DpCPV has the same strong toxicity as that of DpCPV-W1984 (from D. punctatus) to D. punctatus (Walker) larva. So it can be applied to the pine caterpillar control. The DpCPV yield in A.agnata is 2.5×108CPB/larva.

In the present study, A fluorescent imaging-based high-throughput screening method was developed for identifying anti-migratory compounds with 96-well Transwell plates. The correlation, precision and stability of this method were examined and the incubation time of dye Hoechst 33342 in addition to migration time was optimized. In addition, The inhibitory activity of anti-cancer drug paclitaxel on tumor cell migration was assayed and an IC50 value of 0.717 micromol x L(-1) was obtained. Using this method, 24 components from Rhizoma Alismatis were screened and one component with anti-migration activity was found. These results show that the new proposed method with good precision, stability and linear range has the potential to assay the inhibitory activity of anticancer compounds.
