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.

The culture of schistosomiasis control is specific in the history of Chinese culture. Broadly speaking, the culture of schistosomiasis control is a summary of specific social mood, social consciousness and material culture created by Chinese populations during the progress of schistosomiasis control since the founding of the People’s Republic of China. Narrowly speaking, the culture of schistosomiasis control is the spiritual culture that is jointly created and nurtured by schistosomiasis control workers since the founding of the People’s Republic of China. The spiritual features of Chinese schistosomiasis control culture are characterized by the patriotism and care about the people, the matter-to-fact attitude, the pioneering and enterprising spirit, and the spirit of sacrifice and dedication. The ultimate goal of the research on the culture of schistosomiasis control is to facilitate the achievement of the strategic goal of Healthy China 2030 as scheduled, accelerate the progress towards elimination of schistosomiasis, and to promote the sustainable development of schistosomiasis control in China.

This paper describes the current epidemic characteristics and endemic status of schistosomiasis, analyzes the main challenges of schistosomiasis control and proposes the emphasis and interventions for future schistosomiasis control activities in Hunan Province, so as to provide insights into the elimination of schistosomiasis in Hunan Province.

OBJECTIVETo investigate the prevalence and possible factors influencing metabolic syndrome in people from Guizhou Province and to explore the predictive value of the fat-to-muscle ratio in diagnosing metabolic syndrome.

METHODSA multistage stratified sampling method was used in this cross-sectional study of 20-80 years old Han and Bouyei populations from Guizhou Province, southwestern China, from October-December 2012. The study included 4,553 cases of metabolic syndrome, that was defined according to 2005 International Diabetes Federation criteria. The receiver operating characteristic curve was used for determining the sensitivity, specificity, and predictive ability of the fat-to-muscle ratio for the diagnosis of metabolic syndrome.

RESULTSThe age-standardized prevalence of metabolic syndrome was 11.38% (men: 9.76%; women: 12.72%) for Han and 4.78% (men: 4.43%; women: 5.30%) for Bouyei populations. In Guizhou Province, the cut-off value for the men fat-to-muscle ratio was 0.34, the area under the curve was 0.95, and the sensitivity and specificity were 0.94 and 0.85, respectively. The cut-off value for the women fat-to-muscle ratio was 0.55, the area under the curve was 0.91, and the sensitivity and specificity were 0.93 and 0.79, respectively.

CONCLUSIONThe fat-to-muscle ratio is highly predictive of metabolic syndrome in Guizhou Province, and a useful reference indicator.

OBJECTIVETo compare the effects of electroacupuncture (EA) and mild-warm moxibustion (Mox) therapies for constipation-predominant irritable bowel syndrome (C-IBS) patients.

METHODSSixty C-IBS patients were assigned to 2 groups by simple randomized method, i.e. EA group (30 cases) and Mox group (30 cases). Both EA and Mox treatments were performed on bilateral Tianshu (ST 25) and Shangjuxu (ST 37) for 30 min each time, 6 times per week, for 4 consecutive weeks. The gastrointestinal symptoms and psychological symptoms of the two groups were scored before and after treatment. The effects on the corresponding functional brain areas, namely the anterior cingulate cortex (ACC), insular cortex (IC) and prefrontal cortex (PFC) were observed by functional magnetic resonance imaging (fMRI) before and after treatment.

RESULTSCompared with the Mox group, greater improvements in abdominal distension, defecation frequency, diffificulty in defecation and stool features were observed in the EA group (all P<0.01), both Hamilton Anxiety Rating Scale and Hamilton Depression Rating Scale scores were signifificantly decreased in the EA group (all P<0.01). Finally, decreased activated voxel values were observed in the ACC, right IC and PFC brain regions of EA group with 150 mL colorectal distension stimulation (P<0.05 or P<0.01).

CONCLUSIONSBoth EA and Mox could signifificantly improve some of the most intrusive symptoms of C-IBS patients, and EA was more effective than Mox. The therapeutic effect of these two therapies might through modulating of the brain-gut axis function. (Registration No. ChiCTRTRC-11001349).

Objective To explore the clinical effect of non-invasive positive pressure ventilation(NPPV)for treatment of acute left heart failure after mitral valve replacement. Methods Sixty patients with acute left heart failure after mitral valve replacement in Xinxiang Central Hospital from April 2009 to August 2017 were selected. The patients were divided into control group and NPPV group,with 30 patients in each group. The patients in the control group were treated with double oxygen ab-sorption (mask and nasal catheter),strong heart,diuresis and dilated blood vessels. Based on the treatment of control group, the patients in NPPV group were treated with NPPV therapy. The plasma N-terminal pro-B-type natriuretic peptide(NT-proB-NP)level of patients in the two groups was monitored by rapid determination of immunofluorescence before treatment and 6,24 hours after treatment. The respiratory frequency,blood oxygen saturation,heart rate and oxygen partial pressure monitoring of patients in the two groups was monitored before treatment and 2,6 and 24 hours after treatment. Results The total effective rate of patients in the control group and NPPV group was 92. 4％(26 / 28)and 96. 6％(28 / 29)respectively;there was no sig-nificant difference in the total effective rate between the two groups(χ2 = 1. 25,P > 0. 05). There was no significant difference in the plasma NT-proBNP level between the two groups before treatment (P > 0. 05);the level of NT-proBNP at 6,24 h after treatment was significantly lower than that before treatment in the two groups (P < 0. 05);the level of NT-proBNP of patients in the NPPV group was significantly lower than that in the control group at 6,24 h after treatment (P < 0. 05). There was no significant difference in the respiratory frequency,blood oxygen saturation,heart rate and oxygen partial pressure between the two groups before treatment(P > 0. 05). Compared with before treatment,the respiratory frequency and heart rate of patients were decreased and the blood oxygen saturation,oxygen partial pressure were increased at 2,6,24 h after treatment in the two groups (P < 0. 05). There was no significant difference in the oxygen partial pressure between the two groups at 2 h after treat-ment(P > 0. 05);the oxygen partial pressure of patients in the NPPV group was significantly higher than that in the control group at 6,24 h after treatment(P < 0. 05);there was no significant difference in the respiratory frequency,blood oxygen satu-ration and heart rate between the two groups at each time piont after treatment(P > 0. 05). Conclusion NPPV is an effective treatment for acute left heart failure after mitral valve replacement.

OBJECTIVETo explore the effect of homoharringtonine(HHT) combined with imatinib(IM) on proliferation and apoptosis of K562/G01 cells and its potential mechanism.

METHODSK562/G01 cells were cultured with HHT and/or IM. CCK-8 assay was used to detect cell proliferation. Cell apoptosis and phosphorylated tyrosine levels were analyzed by flow cytometry. The expression levels of p210, PI3K, p-Akt and Akt protein were determined by Western blot.

RESULTSCompared with HHT or IM alone, drug combination significantly inhibited cell proliferation and induced apoptosis of K562/G01 cells (both P< 0.05). HHT combined with IM could inhibit the levels of phosphorylated tyrosine and phosphorylated Crkl and downregulate the expressions of p210, PI3K and p-Akt in K562/G01 cells.

CONCLUSIONHHT combined with IM can synergistically inhibit proliferation and induce apoptosis of K562/G01 cells by suppressing the p210 expression and its kinase activity.

Objective To more effectively prevent hypertension and provide better health care for college and university teachers and staff by keeping abreast with the epidemiology of hypertension. Methods The data were extracted from the selected Chinese and English papers on epidemiology of hypertension, which was followed by a meta-analysis of the prevalence, awareness rate, cure rate, and control rate of hypertension in college and university teachers and staff of China. Results A total of 73 papers were included in this study. The total prevalence of hypertension was 23. 3% (95%CI=21. 1%-25. 6%), the prevalence of hypertension was 27. 2% (95%CI=24. 4%-30. 0%) in male hypertensive teachers and staff and was 18. 6% (95%CI=16. 6%-20. 6%) in female hypertensive teachers and staff. The prevalence of hypertension increased with the increasing age and tended to increase with the year of investigation in college and university teachers and staff of China, and was the lowest in East China followed by Central China and West China. The awareness rate, cure rate and control rate of hypertension were 68. 3% (95%CI=59 . 7%-76 . 8%) , 63 . 7% ( 95%CI=55 . 5%-71 . 9%) , and 37 . 7% ( 95%CI=28 . 0%-47 . 5%) respec-tively in college and university teachers and staff of China. Conclusion The prevalence of hypertension is different in college and university teachers and staff of China due to different sexes, ages and areas.

Objective To launch systematic research on long-term asymptomatic hyperuricemia (HUA) from hemorheological viewpoint, so as to provide references for clinical treatment of asymptomatic HUA. Methods Twenty rats were randomly and evenly divided into normal control group and model group. The rats were intraperitoneally injected with 250 mg/(kg•d) oxonate for 8 weeks to induce the model of asymptomatic HUA. The blood samples were obtained to measure the serum uric acid, hemorheological parameters, oxidative and anti-oxidative indices. Results The aggregation index, haemolysis rate, serum xanthine oxidase (XOD), plasma fibrinogen and blood viscosity significantly increased, while the orientation index, electrophoresis rate, serum superoxide dismutase (SOD), activated partial thromboplastin time (APTT) and prothrombin time (PT) significantly induced. Conclusions The asymptomatic HUA can lead to more serious oxidative stress, deteriorate the hemorheological parameters of red blood cells in rats, and induce higher blood viscosity and coagulation status. The research findings indicate that asymptomatic HUA should be correctly understood and timely intervened in clinical diagnosis.
