Aim To evaluate the hypolipidemic effect of the total phenylpropanoid glycosides extracted from Ligustrum robustum (Roxb.) Blume (LRTPG) on hyperlipidemic golden hamsters and explore its regulatory effect on intestinal flora. Methods Sixty hamsters were randomly divided into a control group, a model group, a positive drug group, LRTPG-L group, LRTPG-M group, and LRTPG-H group. After the successful induction of the model by high-fat diet, the animals were continuously administered for four weeks, and their blood lipids and liver lipids were detected. The formed feces from the colorectal region of the hamsters in the control group, model group and LRTPG-H group were collected for 16S rDNA sequencing. Results LRTPG reduced serum TG, TC, LDL-C and liver TG, TC concentrations significantly in hyperlipidemic hamsters. The results of the intestinal microbiota sequencing showed that compared to the control group, LRTPG significantly decreased the relative abundance of the phylum Firmicutes and increased the relative abundance of the phylum Bacteroidetes and Verrucomicrobia (P < 0.01) at the phylum level. At the family level, LRTPG significantly increased the relative abundance of Christensenellaceae, Peptococcaceae, and Verrucomicrobiaceae (P < 0.05 or P < 0.01). At the genus level, LRTPG significantly increased the relative abundance of Oscillospira, Oscillibacter, Flavonifractor and Akkermansiaceae (P < 0.05 or P < 0.01). These changes in the flora were beneficial to the hypolipidemic effect of LRTPG. Conclusion LRTPG may exert its hypolipidemic effect by improving the intestinal flora disorder caused by a high-fat diet in golden hamsters.

OBJECTIVE: To evaluate the efficacy and safety of Tibetan medicine Ruyi Zhenbao Pills (RZPs) in the treatment of patients with motor and sensory dysfunction after stroke. METHODS: A total of 120 convalescent stroke patients hospitalized in the Rehabilitation Department of Guangdong Provincial Hospital of Chinese Medicine from June 2017 to December 2019 were enrolled in this trial. Patients were assigned to control (60 cases) and research (60 cases) groups by computer random assignment. All patients received internal treatment and modern rehabilitation training. On this basis, the research group was given oral RZPs for 4 weeks, while the control group was given oral placebo. The primary outcome was motor function of the affected side evaluated by simplified Fugl-Meyer Motion Assessment Scale (FMA-M). The secondary outcomes included sensory function, activity of daily living (ADL), quality of life, balance function, and pain, which were assessed by Fugl-Meyer Sensory Assessment Scale (FMA-S), Modified Barthel Index (MBI), Special Scale of the Quality of Life (SS-QOL), Berg Balance Scale (BBS), and Visual Analogue Scale (VAS), respectively. All of the assessments were performed before treatment, and 4 and 8 weeks after treatment. Vital signs, liver and kidney functions, routine blood test, blood coagulation profile, and routine urinalysis of patients were monitored. RESULTS: After 4-week treatment, the FMA-M, BBS and FMA-S scores in the research group significantly increased compared with the control group (P<0.05). At 8-week follow-up, the BBS and MBI scores in the research group were higher than the control group (P<0.05). There was no statistical difference between the 2 groups in the SS-QOL and VAS scores at 4 and 8 weeks (P>0.05). Moreover, after treatment, there was no significant difference in vital signs, liver and kidney functions, blood coagulation function, blood routine and urinalysis between the 2 groups (P>0.05). CONCLUSION RZPs improved limb motor, balance, and sensory functions of stroke patients during recovery period with good safety. (Trial registration No. NCT04029701).

Objective:To investigate the effect of total ginsenoside ginseng root on the learning and memory impairment and anxiety of hindlimb suspension rats by detecting the performance of rats in the water maze， elevated plus maze， and the expression of hypothalamic-pituitary-adrenal （HPA） axis， inflammatory factors and tryptophan pathway related factors through the intervention of ginsenosides in hindlimb suspension rats. Method:The Wistar male rats were divided into normal group， hindlimb suspension model group， Huperzine A group （0.1 mg·kg^-1）， and total ginsenoside ginseng root low and high dose groups （100， 200 mg·kg^-1）， with 8 rats in each group. Except for the normal group， the rats in the other groups maintained a -30° hindlimb suspension state for 24 h. The normal group and the model group received intragastric administration of 10 mL·kg^-1 pure water . After 28 days of continuous administration， the water maze and elevated plus maze behavioral tests were performed. After the tests， blood was taken from the abdominal aorta， and the rat brain cortex was peeled off on ice， quenched with liquid nitrogen， and stored at -80 ℃ for later use. LC-MS/MS was used to detect neurotransmitter levels of dopamine， acetylcholine， glutamate， γ-aminobutyric acid and tryptophan pathway metabolites （tryptophan， 5-hydroxytryptamine， 5-hydroxyindoleacetic acid， kynurenine， 3-hydroxykynurenine， and kynurenine） in rat brain cortex. An enzyme-linked immunosorbent assay （ELISA） kit was used to detect the levels of inflammatory factors interleukin-6 （IL-6）， interleukin-10 （IL-10， the HPA axis-related hormone corticotropin （ACTH）， and the level of corticosterone （CORT）. Result:Compared with the normal group， the escape latency in the water maze significantly increased， the number of crossings was significantly reduced， and the number of open-arm entry and the percentage of open-arm entry were significantly reduced in the elevated plus maze in model group （P<0.05， P<0.01）， the content of dopamine， acetylcholine， glutamic acid， and γ-aminobutyric acid in the cortex decreased， kynurenine and kynurenic acid showed an upward trend， 3-hydroxykynurenine， 5-hydroxytryptamine， 5-hydroxyindole acetic acid showed a downward trend， and the levels of IL-6， IL-10， ACTH， and CORT in the serum significantly increased （P<0.05， P<0.01）. Compared with the model group of rats， total ginsenoside ginseng root low and high dose groups group reduced the avoidance latency in the water maze， and increased the number of crossings and the number of open arms of the elevated plus maze， dopamine， acetylcholine， glutamate， and γ-aminobutyl content increased， while kynurenine and kynurenic acid showed a downward trend， 3-hydroxykynurenine， serotonin， and 5-hydroxyindole acetic acid showed an upward trend， and IL-6， IL-10， ACTH， and CORT factor levels were down-regulated（P<0.05， P<0.01）. Conclusion:Hindlimb suspension for 28 days in simulated microgravity can impair the learning and memory ability of rats and cause anxiety-like behaviors. Total ginsenoside ginseng root can improve their learning and memory impairment and anxiety-like behaviors. The mechanism may be mainly related to inhibiting body inflammation and regulating HPA axis imbalance.

Objective To examine the effect of rational emotive therapy on negative emotions among advanced schistosomiasis patients with repeated hospitalizations. Methods A total of 97 advanced schistosomiasis patients with anxiety and depressive emotions that were hospitalized in Xiangyue Hospital of Hunan Institute of Schistosomiasis Control for three times or more were enrolled, and given rational emotive therapy for 4 weeks in addition to routine nursing care. The scores for anxiety, depression and quality of life were estimated in patients before and after the rational emotive therapy using the Self-Rating Anxiety Scale (SRS), the Self-Rating Depression Scale (SDS) and WHOQOL-BREF Form. Results The SAS and SDS scores were significantly lower 4 weeks following rational emotive therapy than before the intervention (SAS score, 45.40 ± 7.77 vs. 59.25 ± 9.29, t = 14.021, P < 0.01; 51.48 ± 8.01 vs. 63.93 ± 9.59, t = 12.991, P < 0.01). The percentages of patients with moderate and severe anxiety and depression were significantly lower 4 weeks following rational emotive therapy than before the intervention (P < 0.01), and the scores for each item in the quality of life were all significantly greater 4 weeks following rational emotive therapy than before the intervention (P < 0.01). Conclusion Rational emotive therapy may improve the negative emotions and the quality of life of advanced schistosomiasis patients with repeated hospitalizations.

OBJECTIVE To explore the hypolipidemic mechanisms of the total phenylpropanoid glycosides from Ligustrum robustum (Roxb.)Blume (LRTPG)in hamsters using proteomics technique. METHODS The hamsters were fed with a high fat diet to induce hyperlipidemia.Then LRTPG of high (1.2 g·kg-1),medium(0.6 g·kg-1)and low(0.3 g·kg-1)doses were administrated daily for 4 weeks.Then the concentrations of plasma and hepatic lipids were determined using enzymic methods.The total protein was extracted from livers of the model group and the group treated with the high dose of LRTPG for label-free quantitative proteomics. RESULTS LRTPG significantly reduced the concentrations of plasma and hepatic lipids in hamsters fed a high fat diet. The proteomics data showed that a total of 2231 proteins were identified,and 549 proteins were found to be differentially expressed between the model group and the group treated with LRTPG.Among the 549 proteins,93 proteins were up-regulated and 59 proteins were down-regulated, and 397 proteins were absent or not. And some of these proteins were much related to the lipid metabolism. Further, gene ontology (GO) analysis indicated metabolic process, transport, oxidation-reduction process, phosphorylation, signal transduction, lipid metabolic process were the main biological processes that those differentially expressed proteins participated. KEGG pathway analysis showed that those proteins were involved in several metabolic pathways including oxidative phosphorylation,non-alcoholic fatty liver disease(NAFLD),PI3K-Akt signaling pathway, cAMP signaling pathway, cGMP-PKG signaling pathway. CONCLUSION The proteomics study could provide valuable clues to help us to understand the hypolipidemic mechanisms of LRTPG much better.

OBJECTIVETo develop a standard Neglect Evaluation Scale which is suitable for rural primary school students in China.

METHODSAccording to the principle of multi-stage stratified cluster sampling, a field investigation was conducted among primary school students in 28 counties from 7 provinces and 2 municipalities. The questionnaires were self-designed, and determined by multiple rounds of pilots and revisions. Among 5 862 students, 2 792 (6-8 years' old) and 3 070 (9-11 years' old) were investigated by using two kinds of Neglect Evaluation questionnaires, respectively. After project analysis, factor analysis, reliability and validity analysis, the reliability and stability of the scale were tested. Then percentile method was used to determine the evaluation standard to develop and finalize the formal scale.

RESULTSThe numbers of the remaining items for 6-8 year-old group and 9-11 year-old group is 69 and 58, respectively, both of which contain six levels of neglect, including body, emotion, health care, education, security, and society. 4 times of factor analysis were conducted in both of the two groups. The factor loadings in these two groups were 0.290-0.700 and 0.276-0.729 respectively. Reliability test results showed that the two kinds of scales' Cronbach alpha coefficient were 0.924 and 0.929 respectively, split-half reliability were 0.891 and 0.904 respectively, the retest reliability were 0.559 and 0.892 respectively, the differences were statistically significant (P < 0.05). The retest reliability among 6-8 year-old group in medical neglect level had no statistical significance, but was close to the cut-off point (P = 0.054). The test results of external validity indicated that both of the two scales could reflect the neglect status of the subjects (P < 0.05), but the subjective and objective evaluation towards neglect were not consistent. The cut-off points for judging whether the children were neglected or not among 6-8 year-old and 9-11 year-old groups were 159 and 137 respectively; and the adjusted values were 160 and 135 respectively.

CONCLUSIONThe two norm scales developed by this study showed good discriminability, reliability, validity, and stability. The norms developed on the basis of the scales was suitable for the situation of rural students in primary schools in China.

This study is to report the study of protective effects of myricitrin against oxidative stress-induced apoptosis of vascular endothelial cells and the investigation of the possible mechanisms of action of myricitrin. The model of H2O2-induced apoptosis of vascular endothelial cells was used to determine the protective effects of myricitrin. The levels of LDH, MDA and the activities of SOD, NO were measured using the respective kits. The H2O2-induced apoptosis of vascular endothelial cells was detected using MTT reduction, TUNEL assay, JC-1 and ROS staining. The activation of Caspase-3 was also measured by fluorometry. The expression of apoptosis-related proteins was determined with Western blotting assay. Myricitrin had significant protective effects against H2O2-induced apoptosis of vascular endothelial cells in a time- and dose-dependent manner. The results show that myricitrin could attenuate H2O2-induced decrease in the activities of SOD (P < 0.01). Myricitrin could decrease the levels of LDH, MDA and increase cell viability and the mitochondrial membrane potential (P < 0.01). Myricitrin had protective effects in a dose-dependent manner between 32 micromol x L(-1) to 64 micromol x L(-1). Myricitrin pretreatment could attenuate H2O2-induced increase of p-ERK. Moreover, myricitrin pretreatment could up-regulate the expression of the anti-apoptotic protein Bcl-2, down-regulate the expression of the pro-apoptotic protein Bax, and decrease the expression of Caspase-3, 9. In conclusion, myricitrin had significant protective effects against H2O2-induced apoptosis of vascular endothelial cells. Myricitrin can enhance the activities of anti-oxidative enzymes and decrease the production of free radicals. The possible mechanisms of action of myricitrin are due to myricitrin-mediated inhibition of phosphorylation of the apoptosis signaling pathways-related kinase ERK, up-regulation of the expression of the anti-apoptotic protein, and down-regulation of the expression of the pro-apoptotic protein.
