Overnutrition during the early postnatal life,a critical time window for growth and development,may induce metabolic syndrome later in life,including overweight/obesity and insulin resistance.The important target organs of insulin,such as liver,adipose tissue,skeletal muscle,and central nervous systems show insulin resistance.The involved mechanisms include abnormality of insulin signal pathway,increment of free fatty acid and some adipocytokines,oxidative stress,maladjustment of orexigenic and anorexigenic neuron,modifications of the hypothalamic-pituitary-adrenal glucocorticoid axis as well as epigenetic,etc.Hence,overnutrition should be avoided during the early postnatal life,so as to decrease the risk of developing long-term insulin resistance.

Objective To investigate the relationship between serum uric acid level and the severity of pregnancy induced hypertension (PIH) in pregnant women with hypertension.MethodsFrom January 2016 to July 2016 in our hospital for treatment of 100 cases of patients with pregnancy induced hypertension, as PIH group, divided into severe hypertension group (33 cases), moderate PIH group (33 cases) and mild PIH group (34 cases), then select 100 cases of normal pregnant women normal pregnancy group.The serum uric acid levels were measured and the results were analyzed.ResultsThe average serum uric acid levels in PIH group (359.75+89.23) mol/L was significantly higher than the control group (188.24+54.54) mol/L in PIH group, the average level of serum uric acid in severe, moderate and mild degree is decreasing, respectively (449.32+81.11), (352.89+76.41), (288.76+59.58) mol/L, a statistically significant difference between the groups (P<0.05).ConclusionThe detection of serum uric acid level in pregnant women can effectively determine the degree of pregnancy induced hypertension in pregnant.

Objective: To introduce recent research progress in anti-diarrhea with single Chinese herb and its effective compo-nents. Methods:The references on anti-diarrhea with single Chinese herb and its effective components in recent years were reviewed and analyzed. Results:The researches on anti-diarrhea activity and possible mechanism of single Chinese herbs, such as Terminalia chebula Retz, Fructus mume, Radix Puerariae and Pulsatilla chinensis ( Bunge) Regel, were reviewed. Conclusion: At present, the researches on anti-diarrhoea with single Chinese herb and its effective components have made some progress, while further and wider researches are still needed to explore the underlying mechanisms.

Objective To explore a simple, effective and stable method for the isolation and purification of Kupffer cells from rat liver, enabling further study on the structure and function of these cells in vitro. Methods After laparotomy, a catheter was inserted into the portal vein and secured with artery clamp. Then, the rat liver was perfused and digested with solution Ⅰ and solution Ⅱ containing 0.05% collagenase Ⅳ respectively. The cell suspension was centrifuged with isopycnic sedimentation in a two-step Percoll gradient to harvest Kupffer cells. The isolated Kupffer cells were purified by selective adherence after 30 min of cultivation, and identified by evaluation of phagocytosis of India ink and peroxidase staining with DAB through light and electron microscopy. Results It was verified that the viability of isolated Kupfffer cells was more than 90% through Trypan blue staining. Those Kupffer cells could attach to plastic quickly and phagocytose ink, and had the appearance of "fried eggs" in positive peroxidase staining with a purity of 95%. Under the light microscopy, the appearance of newly isolated Kupffer cells was round with uniform shape and size. After two days of culture, Kupffer cells appeared to distend with irregular or stellate shape. The typical features were observed in the transmission electron micrographs. There were numerous pseudopods and occasional cup-like indentations in the cell membrane of Kupffer cells. The cytoplasm contained numerous types of lysosomes and other phagocytotic vesicles. Conclusion The method for isolating and culturing Kupffer cells in this study is effective and stable, and the biological characters are preserved in the cultured cells.

[Summary] Fulminant type 1 diabetes (F1D) which is characterized by the abrupt onset of disease , severediabetic ketoacidosis ,high serum pancreatic enzyme concentrations ,and absence of diabetes‐related antibodies is classified astype 1B diabetes. T1DM that developed during pregnancy were mostly F1D. Once occurred ,it would lead to severe outcomes such as stillbirth and death of gravida. One case of pregnancy combined with F1D is reported in this article. We discussed the incidence ,pathogenesis and diagnosis of the disease ,aiming at strengthening the awareness of the disease and also improving the prognosis.

Objective To study the effect of preoperative selective arterial infusion chemotherapy (PSAIC) on large intestine cancer. Methods 63 patients with colorectal cancer underwent PSAIC with 5 fluorouracil,mitomycin and E adriamycin; the changes of clinical manifestation and pathology were observed and analyzed. Results (1)clinical manifestation:abdominalgia relieved in 18 patients and abdominal distention relieved in 16 patients.Improvement of hematochezia was found in 7 patients.In addition, of 13 patients with partial ileus, the clinical symptoms relieved in 9 patients. (2) pathology: there were karyopyknosis,karyorrhexis,coagulation and necrosis of cytoplasm in cancer cells. infiltration of inflammatory cells, edema and fibroelastosis in mesenchyne of cancer tissue. Proliferous intima and thrombus were also observed in the vessels. Most of these changes were moderate,and marked changes could also be seen in necrosis of cytoplasm and vessel intima proliferation. Conclusion PSAIC can control the focus of primary disease and the micrometastatic foci as well as improve the clinical symptoms, such as intestinal obstruction, and hematochezia, so PASIC is helpful to subsequent operation,and can improve the survival rate of patients with colorectal cancer.

OsRacD belonging to rice Rho family of the small GTP binding proteins,is a pivotal gene involved in rice photoperiod fertility conversion of photoperiod sensitive genic male sterile rice,which influences rice fertility via controlling the pollen tube growth.T20N site-directed mutation was introduced into its highly conserved G1 motif by PCR-mediated method to mimic its GDP-binding state based on the sequences alignment and conserved domains analysis.The prokaryotic expression vector of OsRacD and T20N-OsRacD were constructed,and the His6 tag fused proteins were expressed and purified from E.coli.After identified by Western blot,the GTP hydrolysis activities were detected.The results showed that the GTPase activities of T20N-OsRacD were significantly reduced comparing with that of OsRacD,suggested that OsRacD and T20N-OsRacD have different biochemical characteristics.

Although the key role of External Quality Assessment schemes ( EQAS ) in the standardization/harmonization process has been clear from the start, it has never been totally implemented, mainly due to the lack of commutable materials, the difficulty target values and acceptable range.EQAS may also improve standardization/harmonization by proposing rules for the post-examination phase.Improvements in standardization and harmonization will really be able to work under the joint efforts of stakeholders.
