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.

OBJECTIVETo observe the inhibiting effect of acupuncture on blood lipid, myocardial hypertrophy and fibrosis in mice with hyperlipemia, and explore its possible action mechanism.
METHODSTen inbred mice (C57) were applied. Forty ApoE(-/-) mice who removed gene of apolipoprotein E were randomly divided into a control group, a non-acupoint group, an acupoint group and a medication group. The points 0. 5 cm and 1 cm next to the end of mice tail were respectively punctured in the non-acupoint group; "Neiguan" (PC 6) and "Fenglong" (ST 40) were punctured in the acupoint group; intragastric administration of simvastatin was applied in the medication group. After 8 weeks of treatment, the changes of total cholesterol (TC) and ratio of heart to body mass in each group were measured; changes of cardiac muscle fiber and ventricular wall thickness were observed; enzyme linked immunosorbent assay (ELISA) was used to test the level of angiotensin II (Ang I ) in plasma, and western blotting method was used to test protein content of angiotensin II type 1 receptor (AT1R) and endothelin-1 type A receptor (ETAR) in the heart.
RESULTSAfter 8 weeks of intervention, compared with the control group, rising range of blood lipid was obviously decreased (P<0.01) in the acupoint group and medication group, ratio of P<0.01), myocardial heart to body mass was decreased (P<0.05), thickness of ventricular wall was reduced (P fibrosis was relieved, levels of Ang II and ET-1 in plasma were decreased (P<0. 05), content of NO was increased (P<0. 05), and protein content of AT1R and ETAR was decreased in the heart (P<0. 05).
CONCLUSION40) could inhibit the rising of blood lipid in ApoE(-/-) mice, lower the levels of Ang II and ET-1 in peripheral blood, increase the content of NO and inhibit the expression of AT1R and ETAR in heart tissue, which could relieve myocardial hypertrophy and fibrosis to play a protective role on heart.

This study aims to analyze and compare the effect of cell wall-broken decoction pieces, conventional decoction pieces and conventional powder of Rhodiolae Crenulatae Radix et Rhizoma on the intestinal flora of normal mice. The conventional bacterial culture and PCR-DGGE (polymerase chain reaction-denaturing gradient gel electrophoresis) were adopted for the mice after the oral administration for 14 days. According to the bacterial culture results, the 1/8 dose cell wall-broken decoction pieces group showed fewer Enterococcus and Escherichia coli bacillus but more Lactobacillus and Bifidobacterium than the conventional decoction pieces group and the traditional powder group (P <0.05). Meanwhile, on the basis of the PCR-DGGE results, the 1/8 dose cell wall-broken decoction pieces group revealed the highest Shannon-Wiener index (H) and species richness (S) among the seven groups, with extremely significant differences compared with the normal group (P <0.01), significant differences compared with the conventional decoction pieces group and the conventional powder group (P <0.05) and a high intra-group similarity. In conclusion, the long-term intake of 1/8 dose Rhodiolae Crenulatae Radix et Rhizoma cell wall-broken decoction pieces showed a certain effect in regulating intestinal tract by promoting the growth of Lactobacillus and Bifidobacterium. Furthermore, the intestinal flora community will become more stable.

Objective To investigate the operation process of the technology, safety and operability of total laparoscopic resection for colorectal cancer by natural orifice specimen extraction (NOSE). Methods 40 patients with colorectal cancer who met the inclusion criteria of NOSE method from April 2015 to June 2017 were randomly divided into control group (traditional laparoscope) and experimental group (NOSE group), 20 cases in each. The intraoperative and postoperative quality of life between the two groups were statistically analyzed. Results All the patients completed the target operation, and no other operative methods were transferred. No complications occurred in either group. There were statistically difference (P < 0.05) between the two groups of patients in the two indicators (time and blood loss), there was no statistically significant difference in hospital time (P > 0.05), there was statistically difference (P < 0.05) between the two groups of quality of life score (SF-36 scale) in somatic function, role function, pain, cognitive and overall health status of five dimensions, the NOSE group was superior to the traditional laparoscopic group. Conclusion There are advantages in totally laparoscopic colorectal cancer treated with whole NOSE method. The overall health is good, few restrictions on daily work and life, quicker recovery of physical function and role function. Therefore, the application can be promoted if the condition is allowed.

The primers and probes for the Real-time RT-PCR were designed based on the multiple sequence (swine and humans HEV strains) alignments of the ORF3 region of genotype 4 HEV. A rapid, sensitive and stable TaqMan Real-time RT-PCR assay was established, and its specificity and sensitivity were assessed, and comparison of the Real-time RT-PCR with conventional and nested RT-PCR was performed. The results found that the crossing points showed linearly proportional to the logarithm of the input copy number. The correlation coefficient (R2) and the slope value of the standard curves with plasmid DNA were 0.994 and -3.312, respectively. The efficiency (E) of the PCR was 100%. Coefficients of variation values of the different diluted plasmid DNA were low in the same or different repeated experimental group. In addition, the assay was able to correctly detect genotype 4 HEV RNA from swine fecal samples. The sensitivity of established assay was 100-fold higher than that of conventional RT-PCR and 10-fold higher than nested RT-PCR.

Silibinin, a natural flavonoid antioxidant isolated from extracts of the milk thistle herb, has recently been identified as having anti-hepatotoxic and anticancer properties. In this paper, we investigated the effects of silibinin on behavior and neuroplasticity in mice subjected to chronic unpredictable mild stress (CUMS). After 5 consecutive weeks of CUMS, the mice were treated with silibinin (100 mg/kg, 200 mg/kg and 400 mg/kg by oral gavage) for 3 consecutive weeks. The results showed that silibinin administration significantly alleviated the CUMS-induced depressive-like behavior, including the total number of squares crossed and the frequency of rearing in the open field test, the immobility time in the tail suspension test and the forced swimming test. Furthermore, silibinin treatment increased the levels of brain-derived neurotrophic factor (BDNF), serotonin (5-HT) and norepinephrine (NE) in the prefrontal cortex and hippocampus. Our study provides new insight into the protective effects of silibinin on the depressive status of CUMS mice, specifically by improving neuroplasticity and neurotransmission.
