Astragalus membranaceus var. mongholicus and Hedysarum polybotrys belong to different genera, but have similar drug efficacy in traditional Chinese medicine theory, and H. polybotrys was used as the legal A. membranaceus var. mongholicus previously. In this study, similarities and differences between them were analyzed via their ITS/ITS2 fragments information. The ITS (internal transcribed spacer) regions were amplified using polymerase chain reaction and then sequenced in two-way. The alignment lengths of ITS regions were 616 bp, in which 508 loci were consistent, and 103 loci were different, accounting for 82.47% and 16.72% of the total ITS nucleotides in length, respectively. As genotype determines phenotype, 1HNMR-based metabolomic approach was further used to reveal the chemical similarities and differences between them. Thirty-four metabolites were identified in the 1H NMR spectra, and twenty-seven metabolites were the common components. Amino acids, carbohydrates and other primary metabolites were similar, while a large difference existed in the flavonoids and astragalosides. This study suggests that A. membranaceus var. mongholicus and H. polybotrys show similarities and differences from molecular and chemical perspectives, which has laid a foundation for elucidating the effective material basis of drug with similar efficacy and resources utilization.

Ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) coupled with a molecular network analysis strategy was used to identify the chemical constituents of the stem bark of two kinds of asparagus. The chemical constituents were identified by determining an accurate molecular weight, the fragmentation pathway, and comparison with the mass spectrometry data from the references. A molecular network was established based on the similarity of MS/MS fragmentation patterns. A total of 107 compounds were identified or tentatively deduced, which included 46 saponins, 13 flavonoids, and 48 other compounds. The chemical compounds identified in the stem bark of white and green asparagus differed greatly: the white asparagus was rich in saponins, while the green asparagus was rich in flavonoids. In conclusion, the chemical constituents of asparagus stem bark were characterized rapidly using UPLC-Q-TOF-MS/MS and molecular network analysis, with 10 compounds and 45 targets determined from the HIT 2.0 herbal ingredients' targets platform. This work will provide a theoretical basis for the resource utilization of asparagus.

AIM To study the influence and action mechanism of effective components in compatible solution of Sparganii Rhizoma-Curcumae Rhizoma on pelvic adhesions of model rats with chronic pelvic inflammatory disease.METHODS Laboratory rats were randomly assigned into six groups,a sham-operated group,a model group,a positive Fukeqianjin tablets group,compatible solution groups (40 g/kg high-dose group,20 g/kg medi um-dose group,and 10 g/kg low-dose group).Except rats of the sham-operated group,those in the other groups were induced into models of chronic pelvic inflammatory disease by mechanical bacterial strain implantation,after which a 20 d corresponding drug administration by oral gavage for each group was initiated.After completion of the last drug administration,Verco criterion was taken as the reference to evaluate pelvic adhesions,HE staining was performed on uterine tissues for pathological scoring,ELASA method was applied to measuring serum IL-1β and TNF-α levels,and Western blot method was used to detect the expression levels of proteins FGF-2 and IGF-1 in uterine tissues.RESULTS Compared with the model group,the high-dose compatible solution group had a much sharper fall in Verco scores (P ＜ 0.05),and remarkably decreased serum IL-1β and TNF-α levels (P ＜ 0.01);both high-dose and medium-dose groups manifested with notably alleviated degenerative necrosis and lowered scores of chronic inflammation infiltration and epithelial hyperproliferation (P ＜ 0.01 or P ＜ 0.05),and a distinct reduction in the expression of proteins FGF-2 and IGF-1 (P ＜ 0.05,P ＜ 0.01).CONCLUSION The significant improvement of the chronic pelvic inflammatory disease in model rats due to the effective components in the compatibile solution of Sparganii Rhizoma-Curcumae Rhizoma may be associated with inhibited release of inflammatory mediators IL-1β and TNF-α,and the reduced expression of proteins FGF-2 and IGF-1 as well.

OBJECTIVETo probe the relevance between depressive symptoms and hippocampal volume and its metabolites detected by magnetic resonance imaging (MRI) in depressed patients who were given electro-acupuncture (EA) combined with Fluoxetine before and after treatment.

METHODSA randomized, controlled trial was conducted. A total of 75 cases of mild or moderate depression were randomly assigned to two groups: the EA group which received EA combined with Fluoxetine; the Fluoxetine group which received Fluoxetine only as the control. The 17-item Hamilton Scale for Depression (HAMD) was used to assess the depression level. The relevance between the changes of the hippocampal volume and its metabolites, including N-acetyl aspartate (NAA)/creatine (Cr) and choline containing compounds (Cho)/Cr, and the reduction rate of the HAMD score before and after treatment of the two groups were analyzed.

RESULTSAt the end of the treatment, the therapeutic response rates were not statistically different between the two groups (73.53% for the Fluoxetine group and 83.33% for the EA group, respectively). Compared to that of the Fluoxetine group, a significant difference was shown in the EA group in the reduction rate of the HAMD scores (P<0.05). There was a negative correlation between the therapeutic effect and the HAMD scores before treatment in both groups of patients. There was no significant difference in the hippocampal volume before and after treatment. The NAA/Cr ratio of both groups increased after treatment, with the EA group increasing more. There was a negative correlation between the rate of change of the NAA/Cr after treatment and the HAMD scores before treatment in the two groups. In the Fluoxetine group, the Cho/Cr ratio showed no significant difference before and after treatment, which had no relevance with the HAMD scores before treatment either. Meanwhile, in the EA group, the Cho/Cr ratio showed a significant difference before and after treatment, which also had a positive relevance with the HAMD scores before treatment.

CONCLUSIONSThere was a significant improvement in the hippocampal metabolites in depressed patients who treated by EA combined with Fluoxetine. Those differences showed relevance with the HAMD scores before treatment.

OBJECTIVETo determine the molecular mechanisms linking intrauterine growth restriction (IUGR) to adult type 2 diabetes mellitus, the effect of IUGR on the hepatic post-receptor insulin-signaling pathway was investigated in the adult offspring.

METHODSThe IUGR model was prepared by maternal protein-malnutrition. Western blotting analysis was undertaken to assess hepatic expression of insulin receptor substrate (IRS-2), phosphoinositol 3-kinase (PI-3K), protein kinase B (PKB), phosphorylated PKB-Ser473 and glycogen synthase kinase (GSK) 3 in 8-week-old male IUGR rats.

RESULTSThe basal levels of PI-3K protein decreased in IUGR rats compared with normal controls (p<0.01), whereas GSK-3beta protein level significantly increased in IUGR rats (p<0.01). Both PKB and phosphorylated PKB-Ser473 protein levels significantly decreased in the liver of IUGR rats compared with normal controls (p<0.01)). After insulin administration, phosphorylated PKB-Ser473 significantly increased to 182% of basal level in control rats(p<0.01); However, phosphorylation of PKB which responded to insulin was markedly blunted in IUGR rats compared with controls and only increased to 123% of basal level (p<0.05).

CONCLUSIONSThe level of PI-3K and PKB and phosphorylated PKB-Ser473 expression decreased in the liver of IUGR rats, whereas the levels of GSK-3beta protein increased. It may contribute to the pathogenesis of insulin resistance in the IUGR rats.

OBJECTIVETo investigate the biological function of the hepatitis C virus (HCV)-encoded F protein in hepatocytes.

METHODSThe full-length F gene was amplified by PCR from HCV genotype 1a and cloned into plasmid pSEB-3Flag by restriction enzyme digestion and ligation. Hepatoma cell lines, Huh7 and SMMC7721, were transfected with the resultant recombinant pSEB-3Flag-F or the original pSEB-3Flag (negative control) and screened with the selective antibiotic, blasticidin. Stable F gene and protein expression was verified by RT-PCR analysis. Analysis of cell growth and cell cycle was carried out by MTS assay, crystal violet staining and flow cytometry.

RESULTSHuh7 and SMMC7721 cells transfected with pSEB-3Flag-F plasmid (Huh7-F and SMMC7721-F, respectively) uniquely expressed the F gene and protein. The Huh7-F and SMMC7721-F cells showed significantly decreased proliferation rates, compared to the respective control groups. A similar HCV F-mediated growth-inhibiting activity was observed by the cell viability assay. Furthermore, cell cycle analysis revealed that the S-phase distribution was much lower in Huh7-F (47.12%) and SMMC7721-F (30.75%) cells than in the respective controls (55.35% and 33.23%, respectively) (P less than 0.05).

CONCLUSIONStable expression of the HCV F gene reduced the in vitro proliferation rate of hepatoma cell lines, indicating that the F protein may function as a growth inhibitor of infected cells.

OBJECTIVETo analyze the effects to iron status who were given preventive iron supplements for two months from when they were breast-fed to four-month-old.

METHODSA total of 123 infants in four-month-old age who were breast-fed were randomly divided into iron supplementation group (63 cases) and control group (60 cases), iron supplementation group was supplied with low-dose iron (1 mg×kg⁻¹×d⁻¹) for two months with no intervention for control group. Blood samples were collected to test C reactive protein and iron status indicators in six-month-old age group infants, and the growth indices were measured and compared on the gender difference of iron status at and 6 months.

RESULTSAfter 2 months of low-dose iron supplementation, the hemoglobin of iron supplementation group (26 cases) increased about 5.5 g/L while the control group (34 cases) increases about 0.0 g/L (median), 95% confidence intervals were -7.0 - 13.0 g/L and -9.0 - 15.0 g/L, respectively. The hemoglobin increase of iron supplementation group was higher than the control group, the difference was statistically significant (u = -2.326, P < 0.05). The other iron nutritional status and the growth did not show any significant difference between iron supplementation group and control group (P > 0.05). At age 6 month, the MCV of the boys were (75.89 ± 3.34) fl, while the girls were (77.20 ± 3.17) fl. The boys had lower values of MCV than the girls, and the gender difference was statistically significant (t = 4.73, P < 0.05). The other iron nutritional status did not show any significant gender difference (P > 0.05).

CONCLUSIONLow-dose iron supplementation of breast-fed infants at 4-month-old can increase the hemoglobin level when they were 6-month-old, and had no measurable side effect on growth.
