OBJECTIVETo study the correlation between Chinese medical types of coronary heart disease (CHD) [i.e., phlegm turbidity syndrome (PTS) and qi deficiency syndrome (QDS)] and their metabolites.

METHODSRecruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed.

RESULTSMore than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (P<0.05).

CONCLUSIONThe differences in the metabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.

Objective:To investigate the impact of aging on the correlation between the intestinal microorganism Akkermansia and obesity, and to analyze the features of the correlation in the elderly population. Methods:This was a cross-sectional study.A total of 6896 cases were collected from the Guangdong intestinal microbiome in 2018, aged 18-94 years old, including 3806 females, 1641 cases with abdominal obesity(23.7%)and 707 cases with systemic obesity(10.3%). The 16S rRNA sequencing data were from individuals of Cantonese descent.The abundance of Akkermansia was calculated after data cleaning, clustering and annotation.The type of abdominal obesity or systemic obesity was diagnosed based on the standards of the Working Group on Obesity in China(2002). According to the five quintiles of the abundance of Akkermansia, subjects were divided into Q1~Q5(Q1-Q4: n=1379, Q5: n=1380). Logistic regression was used to study the relationship between Akkermansia and obesity after adjusting for common confoundors such as gender.Subjects were subgrouped into two types of age groups: the <65 group(n=5467)and the ≥65 group(n=1519); the <70 group(n=6136)and the ≥70 group(n=850). Age windows were used to analyze changes in characteristics of this relationship with increasing age. Results:There were significant differences in age and gender among different Akkermansia groups( t/ χ2=3.51, -5.03, P<0.01). Logistic regression analysis showed that after adjusting for two main confounding factors, age and gender, the risk of systemic obesity and abdominal obesity gradually decreased from Q2 to Q5 group, compared with Q1 group( P<0.001). The correlation between Akkermansia and obesity decreased with age.The protective effect of Akkermansia on obesity was weaker in the ≥65 and ≥70 groups, respectively, than in the <65 and <70 groups. Conclusions:Akkermansia is a protective factor for obesity, but the protective effect is affected by aging and weakened in the elderly.

Hypoxia is a general characteristic of most solid malignancies and intimately related to cancer progression. Homeostatic response to hypoxia is primarily mediated by hypoxia inducible factor-1alpha (HIF-1alpha) that elicits transcriptional activity through recruitment P300 coactivator. Targeting the interaction of HIF- alpha and P300 would thus constitute a novel approach for cancer treatment by suppressing tumor angiogenesis and metastasis. Here, a screening assay was developed for inhibitors targeting the interaction between HIF-1alpha and P300. The nucleotide sequence of human HIF-1alpha and P300 were cloned into pBIND and pACT vectors, named pBIND-HIF1alpha and pACT-P300. The interaction of HIF-1alpha and P300 was identified in HEK293 cell using mammalian two-hybrid system. And compound chetomin decreased their interaction in this mammalian two-hybrid system. We further verified HIF-1 inhibition effect of chetomin in U251-HRE cells. Therefore, we established a screening assay combined HIF-1alpha and P300 mammalian two-hybrid system and U251-HRE reporter assay for HIF-1 selective inhibitors.

Objective: The alcohol extraction and water precipitation processes of Shenmai Injection were optimized based on quality by design (QbD) concept and satisfaction algorithm. Methods: Hazard and operational analysis method was applied to conduct risk assessment of various process parameters in alcohol extraction and water precipitation processes of Shenmai Injection. Ethanol concentration, extraction time and alcohol-material ratio were selected as the critical process parameters of alcohol extraction, and the material pH, temperature and time were selected as the critical process parameters of water precipitation. A multiple linear regression model of critical process parameters and critical quality attributes were established by using Box-Behnken design. A design space was delineated according to the level of each index. Finally, the optimum operating condition was determined by the multi-index optimization algorithm. Results: Within the scope of the design space, when the alcohol concentration was 89.0%, the extraction time was 110 min, the alcohol-material ratio was 2.99, the desirability function of alcohol extraction of 0.722 was the best. When the material pH was about 4, the time was 40 h, the temperature was 2.0 ℃, the desirability function of water precipitation of 0.995 was the best. When the material pH was about 5, the time was 35 h, the temperature was 2.0 ℃, the desirability function of water precipitation of 0.999 was the best. Conclusion: The optimal conditions were determined based on QbD and satisfaction algorithm were conducive to ensuring the product quality and reducing the cost of production. This study has reference value for the guidance of pharmaceutical process research and actual industrial production.

OBJECTIVETo explore the correlation between the content of the secondary metabolites and the anti-bacterial activity of Sargentodoxa cuneata tables.

METHODSThe content of secondary metabolies was determined by spectrometers. Staphylococcus aureus and Bacillus subtilis were used as the experimental strains. The minimal inhibition concentration (MIC) was calculated using agar plate dilution method on Kirby-Bauer disk. The minimal bacterialcidal concentration (MBC) was calculated using tube dilution method. Two-way analysis and Turkey's test was employed in the statistical analysis.

Those of the second batch of S. cuneata tables produced in Jiangsu was the lowest [the diameter of anti-bacterial zone, MIC, MBC was (7.67 +/-0.29)mm, 25 mg/ml, 125 mg/ml and (8.17 +/-0.29)mm, 25 mg/ml, 125 mg/ml, respectively]. There was significant difference in the antibacterial activity on Staphylococcus aureus between different producing areas of S. cuneata tables and batches (P<0.01), while there was also significant difference in the antibacterial activity on Bacillus subtilis between different producing areas (P<0.01) and no significant difference between different batches (P>0.05). The contents of 6 secondary metabolites of S. cuneata tables produced in different areas and in different batches were different. The total content of 6 secondary metabolites of the first batch of S. cuneata tables produced in Anhui was the highest with mean 3.61%. Those of the second batch produced in Jiangsu were the lowest with mean 1.90 %. There was significant difference in the content of total alkaloid and dissociated emodin between different producing areas (P<0.01) and no difference between different batches (P>0.05). For the content of total chlorogenic acid, flavonoids, total tannin and total saponin, there was significant difference between different producing areas and batches (P<0.01). The correlation analysis showed that the main secondary metabolites influencing the anti-bacterial activity were total saponin, total tannin, dissociated emodin and total chlorogenic acid.

CONCLUSIONThere is difference among the content of the secondary metabolites and anti-bacterial activity of S. cuneata tables produced in different areas and different batches. There is significant correlation of the anti-bacterial activity with the content of total saponin, total tannin, dissociated emodin and total chlorogenic acid in S. cuneata tables.

Osteoarthritis (Osteoarthritis, OA) is a common clinical degenerative joint disease with increased incidence rate in recent years. Animal experiment is one of the important ways to explore pathogenesis and treatment of OA, while induced animal model is the most important part in animal experiment. Intra-articular injection of drugs is a classical method for establishing animal model of OA. Choose of animal should follows the principle of correlation, appropriateness and practicability, injections should perform in accordance with experimental purposes and subject, detections means and evaluation methods also should corresponding to experimental reality. The gold standard of OA animal model and intra-articular injections has not build, need further study.

The aim of this study was to evaluate the homing capabilities of hematopoietic stem/progenitor cells (HSPCs) derived from human placenta tissues (PT). Single cell suspension of human PT was prepared by mechanical method. The expression levels of homing-related adhesion molecules (HRAM) including CD11a, CD49d, CD44, CD49e, CD62L and CD54 on CD34(+) cells and the percentages of CD34(+) cells and their subpopulations in nucleated cells (NC) from fresh human PT, umbilical cord arterial blood (UCAB) and umbilical cord venous blood (UCVB) were detected by using flow cytometry. The results showed that the percentage of CD34(+) cells and CD34(+)CD38(-) cells in placenta were higher than those in UCAB and UCVB. There were no significant difference in percentage of HSPC between UCAB and UCVB. Placenta-derived CD34(+) cells strongly expressed CD11a, CD49d, CD44, CD49e and CD54, among which expression levels of CD49e and CD54 on placenta-derived CD34(+) cells were significantly higher than those on UCAB and UCVB-derived CD34(+) cells. While the percentage of CD34(+)CD62L(+) cells in placenta was only lower than that in UCVB. It is concluded that human placenta is rich in HSPC. Moreover, the expression levels of most HRAM in CD34(+) cells from PT are higher than those from UCAB and UCVB or are close to them. It suggested that HSPCs derived from PT might have stronger homing capabilities than those from UCB.
