OBJECTIVETo provide new germplasm materials for breeding new varieties of Pseudostellaria heterophylla.
METHODThe method of single plant selection was adopted, with the comparative experiments being carried out under the same conditions in Shibing county. The 8 plants of Shibing SB-4 were compared respectively with factor analysis for 27 phenotypic traits and 8 yield traits, and single factor variance analysis for the contents of polysaccharides.
RESULTUsing factor analysis, 27 phenotypic traits were classified into 7 principal divisors and 8 yield traits were simplified into 3 principal divisors. The 4 strains of P. heterophylla, ZT-01, ZT-02, ZT-06 and ZT-07, performed better than others in the phenotypic traits, and ZT-01, ZT-02, ZT-03 and ZT-07 in the yield traits. The contents of polysaccharides of ZT-01, ZT-02, ZT-05 and ZT-08 showed significantly higher value.
CONCLUSIONThere is significant difference among the 8 strains of P. heterophylla in phenotypic traits, yield traits and quality traits, making it possible to select certain strains for different purposes. ZT-01 and ZT-02 can be breaded further. ZT-06 and ZT-07 were used as ornamental cultivars for its great phenotypic traits. ZT-03 with good resistance and high yield was taken as resistant variety, and ZT-05 would face next selection on the basis of its high content of polysaccharide.

To study the effect of liquiritin (Liq) on the transport of strychnine (Str) in Caco-2 cell monolayer model, the transport parameters of Str, such as apparent permeability coefficient (P app (B-->A) and P app (A-->B)) and cumulative transport amount (TRcum), were determined and comparatively analyzed when Str was used solely and co-used with Liq. The effect of drug concentrations, conveying times, P-glycoprotein (P-gp) inhibitor verapamil and conveying liquor pH values on the transport of Str were also investigated. The results indicated that the absorption of Str in Caco-2 cell monolayer model was well and the passive transference was the main intestinal absorption mechanism of Str in the Caco-2 monolayer model, along with the excretion action mediated by P-gp. Liq enhanced the absorption of Str. Meanwhile, conveying liquor pH value had significant influence on the excretion transport of Str.

To study the effects of major components of Maijunan tablets, puerarin (Pue) and rhynchophylline (Rhy) on the transport of hydrochlorothiazide (Hct) Caco-2 cell monolayer model, the transport parameters of Hct, such as apparent permeability coefficient (P(app) (B --> A) and P(app) (A --> B)) and the ratio of P(app) (B --> A) versus P(app) (A --> B), were studied and compared when Hct was used solely and co-used with Pue and/or Rhy. The effects of drug concentrations, conveying times, P-glyprotein (P-gp) inhibitor verapamil and conveying Liq pH values on the transport of Hct in the above conditions were also investigated. The results indicated that the absorption of Hct in Caco-2 cell monolayer model could be a carrier-mediated active transport, along with the excretion action mediated by P-gp. Pue can decrease the excretion action of Hct mediated by P-gp, and Rhy had no significant effect on the transport of Hct. The co-use of Hct, Pue and Rhy enhanced the absorption of Hct. Meanwhile, conveying Liq pH value had significant influence on the transport of Hct. The absorption of Hct at pH 6.0 was higher than that at pH 7.4.

OBJECTIVETo investigate the relationship between adiponectin and beta-cell function in abdominal visceral obesity women.
METHODSNine abdominal visceral obesity women (VO), 9 normal subjects (C) and 7 patients with type 2 diabetes mellitus (T2DM) were enrolled in the study. Beta-cell function and insulin sensitivity were determined by hyperglycemic clamp, fasting serum adiponectin was assayed by ELISA and regional body fat was measured by MRI.
RESULTThe levels of first phase insulin release (FPIR), glucose disposal rates (GDR), insulin sensitivity index (ISI) and adiponectin were significantly elevated in control group compared with VO group and T2DM group. As compared with T2DM group, the levels of adiponectin, FPIR, second phase insulin release (SPIR) and maximum insulin release (INS(max)) increased significantly in VO group. Multiple stepwise regression analysis showed that age, FPIR and GDR were positively correlated to adiponectin (B=0.145, 0.194, 0.277 respectively, all P<0.05), while waist-hip ratio was negatively correlated with adiponectin (B=-7.424, P<0.05).
CONCLUSIONThe visceral obesity women have lower adiponectin levels, and hyperadiponectinemia may be the link with insulin secretion.

OBJECTIVETo investigate the risk factors for the development of congenital anal atresia in neonates.
METHODSA total of 70 neonates who were admitted to 17 hospitals in Foshan, China from January 2011 to December 2014 were enrolled as case group, and another 70 neonates who were hospitalized during the same period and had no anal atresia or other severe deformities were enrolled as control group. Univariate and multivariate logistic regression analyses were used to investigate the risk factors for the development of congenital anal atresia.
RESULTSThe univariate analysis revealed that the age of mothers, presence of oral administration of folic acid, infection during early pregnancy, and polyhydramnios, and sex of neonates showed significant differences between the case and control groups (P<0.05). The multivariate logistic regression analysis revealed that infection during early pregnancy (OR=18.776) and male neonates (OR=9.304) were risk factors for congenital anal atresia, and oral administration of folic acid during early pregnancy was the protective factor (OR=0.086).
CONCLUSIONSInfection during early pregnancy is the risk factor for congenital anal atresia, and male neonates are more likely to develop congenital anal atresia than female neonates. Supplementation of folic acid during early pregnancy can reduce the risk of congenital anal atresia.

This study aims to explore the pharmacodynamic differences of Puerariae Lobatae Radix(PLR), Puerariae Thomsonii Radix(PTR) and their different processed products and the influences of these medical materials on the diversity of intestinal flora. The Sennae Folium-induced diarrhea model, streptozotocin(STZ)-induced diabetes model and L-nitro-arginine methyl ester(L-NAME)-induced hypertension model were used to compare the pharmacodynamic differences in anti-diarrhea, blood glucose reduction and blood pressure lowering among raw, roasted and vinegar-processed PLR and PTR. The effects of raw and processed PLR and PTR on intestinal flora diversity of rats were evaluated by 16 S rDNA high-throughput sequencing. The roasted PLR and PTR performed better in anti-diarrhea, especially the former. PLR and its processed products all presented the efficacy of reducing blood glucose, and the vinegar-processed PLR was the most outstanding. The raw PTR was not that effective in reducing blood glucose, whereas its efficacy was improved after roasting and vinegar processing. Both PLR and PTR were capable of lowering blood pressure to a certain extent, and PLR is superior to PTR in this aspect. Further, the vinegar-processed PLR showed the best effect. The diversity of intestinal flora was different among rats to which different products of PLR and PTR were administered. The roasted PLR led to the highest abundance of Lactobacillus, which was closely related to its best antidiarrheal effect. The highest abilities of vinegar-processed PLR to lower blood glucose and blood pressure were associated with the high abundance of Blautia and Prevotella_9. This study lays a foundation for elucidating the processing mechanisms of PLR and PTR and provides a basis for their further development and application.

Both anti-glomerular basement membrane (GBM) disease and the anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are common causes of pulmonary-renal syndrome. Organizing pneumonia (OP), a special pattern of interstitial lung disease, is extremely rare either in AAV or anti-GBM disease. We report an old woman presented with OP on a background of co-presentation with both ANCA and anti-GBM antibodies.
