ABSTRACT

Objective:To explore the molecular mechanism of modified Guizhi Fulingwan in rats with uterine fibroids. Method:Seventy-two female adult SD rats of SPF grade were randomly divided into a model group, a normal group, and a preventive administration group. The model group and preventive administration group were established by estrogen and progestin loading method. After successful modeling, the rats in the model group were randomly divided into a western medicine group (mifepristone), the high-dose traditional Chinese medicine(TCM) group, and a low-dose TCM group. All the rats were dosing as required once a day for 28 consecutive days. Hematoxylin-eosin(HE)staining was used to observe the morphological changes of the uterus. The micRNA gene chip was used to detect the expression profile of uterine micRNA gene. Differential expressions of micRNA were screened by bioinformatics methods. Gene function enrichment was used to predict the possible signaling pathways in rats with uterine fibroids by modified Guizhi Fulingwan. Result:Compared with the normal group, microRNA of the model group was 1 up-regulated and 9 down-regulated. Compared with the model group, microRNA of the high-dose group of TCM group was 2 up-regulated and 1 down-regulated, in the preventive administration group, 9 was up-regulated and 2 was down-regulated. Gene function enrichment analysis indicated that four signaling pathways were closely related to uterine fibroids. They were mitogen-activated protein kinase (MAPK) signaling pathway, Wnt signaling pathway, mammalian rapamycin target protein (mTOR) signaling pathway and vascular endothelial cell growth factor (VEGF) signaling pathway. Conclusion:Modified Guizhi Fulingwan affected the expression profile of micRNA in rat model of uterine fibroids induced by estrogen and progesterone, suggesting that modified Guizhi Fulingwan may involve in a variety of biological processes such as signal transduction and gene regulation in the treatment of uterine fibroids.

ABSTRACT

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<sup>-1</sup>), and total ginsenoside ginseng root low and high dose groups (100, 200 mg·kg<sup>-1</sup>), 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<sup>-1</sup> 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, <italic>γ</italic>-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 (<italic>P</italic><0.05,<italic> P</italic><0.01), the content of dopamine, acetylcholine, glutamic acid, and <italic>γ</italic>-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 (<italic>P</italic><0.05, <italic>P</italic><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 <italic>γ</italic>-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(<italic>P</italic><0.05, <italic>P</italic><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.

ABSTRACT

In rodents, bilateral olfactory bulbectomy (OBX) results in a series of changes in behaviors and neurobiology, similar to the clinical symptoms of depression in patients. These changes can be reversed by chronic but not acute treatment of antidepressants. Owing to the face, construct and predictive validities, the OBX model has been used to investigate the mechanisms of depression, screen for antidepressants, and reveal the mechanism of drug action. In addition, there are certain features in OBX animals resembling those of patients with Alzheimer's disease (AD), including the impaired learning and memory ability and the accumulation of amyloid-β protein (Aβ). In this review, we present the association between olfaction and depression or AD, the surgical procedure of OBX, the behavioral features of OBX animals, the abnormal changes in cortex and hippocampus, and the application of this model for studying depression and AD. These lines of information are important for the development of antidepressant and anti-dementia drugs using this model.

ABSTRACT

Progressive accumulation of the amyloid-β peptide (Aβ) in the brain plays a central role in the pathogenesis of Alzheimer's disease (AD). The animal model of intracerebral injection of Aβ oligomers not only provides a method for further exploring the mechanism of Aβ in AD, but also can be used to screen drug candidates targeting Aβ oligomers. This animal model has been widely used in the study of anti-AD drugs and mechanism of AD. In this paper, we summarize the research progress in the animal model of intracerebral injection of soluble Aβ oligomers, including experimental animals, the types of Aβ, the preparation of Aβ oligomers in vitro, injection sites and doses, the duration of modeling, animal behavioral changes, and the pathological mechanisms relating to this animal model, which will contribute to the application of the animal model to various conditions.

ABSTRACT

Objective To investigate the influence of body mass index(BMI) on the prognosis of patients who had received elective PCI.Methods The study population consisted of 2964 consecutive patients with electivePCIs performed between July 2009 and September 2011. The patients were divided into three groups based on their preoperative BMI levels:the normal group( BMI<24.0 kg/m2,n=810); the overweight group( 24.0 kg/m2≤BMI<28.0 kg/m2,n=1454) and the obese group(BMI≥28.0 kg/m2,n=700). We examined the association between baseline BMI levels and postoperative mortality through a mean(571.5±130.8)days of follow up.Results Patients with high BMI had a higher percentage of comorbidities compared with the normal BMI group. The results of multivariate Cox regression analysis revealed that preoperative BMI was inversely associated with mortality after adjustment for other factors (HR 0.896,95% CI 0.821-0.977,P=0.031). Compared with the obese group, the hazard ratios for risk of mortality in the overweight and the normal groups were 1.908(95%CI 0.689-5.291,P=0.213) and 2.241(95%CI 1.154-4.350,P=0.017).Conclusions For patients undergoing elective PCI, individuals with obesity and overweight had the better prognosis than those with normal BMI.

ABSTRACT

To investigate whether the extract of Dendrobium nobile Lindl (DNL) has an antidepressant effect on chronic unpredictable mild stress (CUMS)-induced depressive mice, 72 BALB/c male mice were randomly divided into the control group, the CUMS model group, the extract of DNL groups (50, 100 and 200 mg/kg DNL, i.g.) and the paroxetine group (10 mg/kg, i.g.). The different doses of DNL or the paroxetine was administered orally once daily to CUMS mice for 8 weeks (containing two-week preventive medication before the modeling). The same volume of distilled water was given to the control group and the CUMS group. Except for the control group, the other mice were exposed to chronic stress for 35 days. Behavioral tests were performed by using the sucrose preference test (SPT), the novelty-suppressed feeding (NSF) test, the tail suspension test (TST), and the forced swim test (FST). The levels of dopamine (DA) and 5-hydroxytryptamine (5-HT) were measured by the liquid chromatography-mass spectrometer (LC-MS)/MS. Compared with the control group, obvious behavioral changes were observed in the CUMS group after 5-week CUMS, including a decrease in the sucrose consumption, an increase in the latency to feeding in the NSF test and a prolongation of the immobility time in the TST. Compared with the CUMS group, the application of DNL resulted in a dose-dependent increase in sucrose consumption (P < 0.01) as paroxetine (10 mg/kg) did and a significant dose-dependent decrease in the latency to feeding in the NSF test (P < 0.05). In the TST, the application of paroxetine (10 mg/kg) and the high-dose DNL (200 mg/kg) obviously decreased the immobility time when compared with the CUMS group (P < 0.05). In the FST, compared with the CUMS group, all the groups had no significant differences in the immobility time (P > 0.05). In addition, in the hippocampus and cortex, the levels of 5-HT and DA were significantly decreased in the CUMS group compared with the control group (P < 0.05). In comparison with the CUMS group, paroxetine obviously increased the DA levels in the hippocampus and the cortex and the 5-HT level in the hippocampus (P < 0.05). DNL (50 and 200 mg/kg) significantly increased the DA level in cerebral cortex of the brain, and DNL (100 and 200 mg/kg) increased the DA level in the hippocampus. The 5-HT level in the 200 mg/kg DNL group was notably increased in both two brain regions (P < 0.05), but the 5-HT level in the 100 mg/kg DNL group was significantly increased only in the hippocampus (P < 0.01). These findings indicate that the extract of DNL has an antidepressant-like effect on CUMS-induced depressive mice and its mechanism may be related to the changes in DA and 5-HT in the hippocampus and cortex.

ABSTRACT

<p><b>OBJECTIVE</b>Coronary artery calcification (CAC) is a well-established risk predictor of coronary heart disease events and is recognized as an indicator of subclinical atherosclerosis.</p><p><b>METHODS</b>A cross-sectional study consisting of 2999 participants aged ⋝40 years from the Jidong community of Tangshan City, an industrial and modern city of China, was conducted between 2013 and 2014 to examine the association between the ideal cardiovascular health (CVH) metrics and CAC. The ideal CVH metrics were determined based on the definition of the American Heart Association (AHA). The participants were then grouped into 4 categories according to the quartiles of their CVH metric scores as follows: first quartile (0-2), second quartile (3), third quartile (4), and fourth quartile (5-7). CAC was assessed by using high-pitch dual-source CT, and patients were identified based on thresholds of 0, 10, 100, or 400 Agatston units, as per common practice.</p><p><b>RESULTS</b>The prevalence of subclinical atherosclerosis was 15.92%, 13.85%, 6.76%, and 1.93%, determined by using the CAC scores at thresholds of 0, 10, 100, and 400 Agatston units, respectively. Compared with the group in the first quartile, the other three CVH groups had a lower odds ratio of CAC >0 after adjusting for age, sex, income level, education level, and alcohol use in the logistic regression analysis. The odds ratios in these groups were 0.86 [95% confidence interval (CI), 0.63-1.17; P<0.05], 0.75 (95% CI, 0.55-1.02; P<0.05), and 0.49 (95% CI, 0.35-0.69; P<0.05), respectively. These associations of CAC with the CVH metrics were consistent when different CAC cutoff scores were used (0, 10, 100, or 400).</p><p><b>CONCLUSION</b>The participants with more-ideal cardiovascular metrics had a lower prevalence of subclinical atherosclerosis determined according to CAC score. Maintaining an ideal cardiovascular health may be valuable in the prevention of atherosclerosis in the general population.</p>

ABSTRACT

By comprehensive review and analysis of post-marketing clinical research on the efficacy and safety,we concluded that Fufang Zaoren capsule has certain therapeutic effects for insomnia, although current clinical research design needs improving. The post-marketing clinical studies also showed that it causes several adverse reactions at the recommended doses, such as chills, fever, dizziness, nausea, shortness of breath, chest tightness and palpitations, whereas high doses of Fufang Zaoren capsule can cause delayed extrapyramidal symptoms. Health Canada government website also prompted the L-tetrahydropalmatine in Fufang Zaoren capsule caused liver damage in pregnant women. The authors summarized the risk points, factors and risk control in the clinical use of Fufang Zaoren capsule and also present their perspective on the research status, existing problems and corresponding countermeasures in the post-marketing clinical re-evaluation of traditional Chinese medicine.

ABSTRACT

This study is to investigate the protective effect of longistyline A against corticosterone-induced neurotoxicity in PC12 cells. While PC12 cells were exposed to 100 micromol x L(-1) corticosterone for 48 h, cell survival rate was reduced and lactate dehydrogenase (LDH) release increased. In parallel, corticosterone caused significant elevations of DNA fragmentation, [Ca2+]i and caspase-3 activity. However, when the PC12 cells were incubated with longistyline A (4.0, 8.0 and 16.0 micromol x L(-1)) in the presence of 100 micromol x L(-1) corticosterone for 48 h, the effects were evidently alleviated, but dose-dependent manner was not obvious. In summary, longistyline A could generate a neuroprotective effect against corticosterone-induced neurotoxicity in PC12 cells possibly by decreasing [Ca2+]i and caspase-3 activity.

ABSTRACT

<p><b>BACKGROUND</b>Coronary slow flow phenomenon (CSFP) is an important, angiographic clinical entity but is lacking non-invasive detecting techniques. This study aimed to elucidate the value of transthoracic Doppler echocardiography (TTDE) in the diagnosis and monitoring of coronary slow flow in left anterior descending (LAD) coronary artery.</p><p><b>METHODS</b>We consecutively enrolled 27 patients with CSFP in LAD detected by coronary arteriography from August 2009 to April 2010. Thirty-eight patients with angiographically normal coronary flow served as control. Corrected thrombolysis in myocardial infarction (TIMI) frame count (CTFC) was used to document coronary flow velocities. All subjects underwent TTDE within 24 hours after coronary angiography. LAD flow was detected and the coronary diastolic peak velocities (DPV) and diastolic mean velocities (DMV) were calculated.</p><p><b>RESULTS</b>Sixty of 65 (92.3%) subjects successfully underwent TTDE. Baseline clinical characteristics were similar between the two groups. Coronary DPV and DMV of LAD were significantly lower in the CSFP group than in the control group ((0.228 ± 0.029) m/s vs. (0.302 ± 0.065) m/s, P = 0.000; (0.176 ± 0.028) m/s vs. (0.226 ± 0.052) m/s, P = 0.000, respectively). There was a high inverse correlation between CTFC and coronary DPV and DMV (r = -0.727, P = 0.000; r = -0.671, P = 0.000, respectively). Receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) was less than one half for coronary DPV (AUC = 0.104) and DMV (AUC = 0.204), respectively.</p><p><b>CONCLUSIONS</b>In patients with CSFP, there is a high inverse correlation between CTFC and coronary diastolic flow velocities in the LAD coronary artery, as measured by TTDE. The value of TTDE in the monitoring and evaluation of coronary flow in patients with CSFP deserves further investigation.</p>

ABSTRACT

Objective To investigate the type 2 diabetes mellitus(T2DM)prevalence and related risk factors in adult population with obesity in Tianjin. Methods With stratified cluster randomized sampling, 2888 obese people with BMI≥28 kg/m2, aged 18 years old and over were selected from three urban and three rural regions of Tianjin, in 2006. Information on risk factors was collected with questionnaire through face-to-face interview by trained workers and data on fasting blood glucose(FBG)was collected at the same time. 2hrPPG was tested among the people who' s FBG ≥6.1 mmol/L at the hospital. Prevalence of T2DM was calculated and the distribution of T2DM in the described subgroups and the risk factors analyzed with SPSS software. Results The prevalence of T2DM in adult population with obesity was 11.74%, with females(13.90%)higher than males (8.75%). The prevalence rates of T2DM were statistically different among different groups, classified by age, education, occupation, district and BMI. Results from the univariate and multivariate logistic regression analysis showed that the risk factors of T2DM were age(OR=1.383, 95% CI: 1.254-1 .525)and sex(OR= 1.591,95% CI: 1.230-2.059)while the protective factor was fruit intake(OR=0.867, 95% CI: 0.774-0.971). Conclusion The prevalence of T2DM in adult with obesity was considered to be high. The distribution of T2DM in different subgroups and affecting factors of T2DM in obese adults were different from general population.

ABSTRACT

Objective This study aimed to explore the epidemiological characteristics and related factors of overweight and obesity in Tianjin adults. Methods With multi-stage randomized cluster sampling, 19 271 people aged 18 years and over were selected from both urban and rural areas of six geographical regions of Tianjin in 2006, using a cross-sectional methodology. Data from these residents was collected, using a questionnaire by face-to-face interview conducted by trained interviewers. Demographic, anthropometric data were collected in all participants. Data was analyzed with SPSS 13.0 software. For diagnosis of overweight and obesity, we adopted the standard of overweight and obesity recommended for Chinese adults. Age, gender and area distribution of overweight and obesity in the population of Tianjin were described, and the related factors were analyzed. Results Prevalence of overweight and obesity in adults from Tianjin were 32.8%(95%CI: 32.1%-33.5%) and 11.7% (95% CI: 11.2%-12.2%), with the standardized rates as 33.1% and 12.2%, respectively. Those figures were higher than the national average levels. The prevalence rates of overweight and obesity were increasing with age. The overweight rate in 50-59 year olds and the obesity rate in 60-69 year olds reached their peak values. The prevalence rate of obesity was higher in rural (13.5%,with 95%CI: 12.8%-14.2%) than in the urban areas (11.1%,with 95%CI: 10.4%-11.7%) and in females (12.6%,95%CI: 11.9%-13.2%) than in males (10.9%,95%CI: 10.3%-11.5%). Results from logistic regression model analyses indicated that the prevalence of overweight and obesity in Tianjin were statistically associated with age, gender, educational level, smoking, alcohol consumption and exercises. Conclusion As the urbanization progressing, the prevalence of overweight and obesity was much higher in the population of Tianjin city. Many factors were related to adults overweight and obesity. An active community-based public health intervention should be taken.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the changes and clinical significance of serum Apelin in patients with severe sepsis and septic shock.</p><p><b>METHOD</b>We measured the serum level of Apelin with ELISA on different observation days (the 1st, 3rd, and 10th day obtaining the diagnosis) in 26 patients with severe sepsis and septic shock.</p><p><b>RESULTS</b>Serum Apelin significantly increased in sepsis patients when compared with the normal control group (P<0.01); The serum Apelin levels significantly changed among different observation days (P< 0.01). Serum Apelin level was significantly higher in patients with septic shock than those with severe sepsis (P<0.01).</p><p><b>CONCLUSION</b>Serum Apelin level changes in patients with severe sepsis and septic shock, which may provide clues in diagnosis and prognosis.</p>

ABSTRACT

The paper summarized the sedative pharmacological effects of CMM, which were reported in the past 10 years. Those sedative CMMs were found in several type of Chinese medicine, such as tranquilizing the mind, calming the liver to stop the wind, general tonic, blood-activating and stasis-resolving drugs, heat-clearing drugs, exterior-releasing drugs, drugs for resuscitation, diuresis-inducing and dampness-draining drugs, ect. Out of them, the general tonic drugs were used in many occasions. Two Chinese herbs, jujube seed and polygala were used popularly as sedative drugs. And their effects have something to do with heart Meridian and liver Meridian. The Locomotor activity, sleeping test and forcing swimming were used commonly to detect the sedative effects. The sedative mechanisms of those CMM were related with neuro-transmitters such as Dopamine (DA), 5-HT and gamma-GABA, etc.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the risk factors related to mortality in old patients with coronary heart disease after revascularization.</p><p><b>METHODS</b>A total of 675 patients (498 males) with age >or= 70 years old who received revascularization during July 2003 to June 2004 and followed up > 30 days after discharge were included in this study. Clinical characteristics, death and major adverse cardiac and cerebral events (MACCE) during follow up were recorded.</p><p><b>RESULTS</b>The patients were followed up for a mean period of (754 +/- 355) days. 27 patients (4.0%) died and MACCE developed in 50 patients (7.4%) during follow up. Female and patients with anemia took a significantly higher risk of mortality (RR = 2.750, 95% CI 1.116 - 6.779, P = 0.028, RR = 0.385 95% CI 0.164 - 0.904, P = 0.028, respectively); Creatinine level is positively related to mortality rate. When comparing patients with Cr > 115 micromol/L and Cr > 177 micromol/L with patients with Cr < 115 micromol/L, the hazard rate was 2.963 and 10.785, respectively (95% CI 1.114 - 9.952, P = 0.035 and 95% CI 2.659 - 78.097, P = 0.000) after adjustment for other risk factors.</p><p><b>CONCLUSION</b>Preexisting anaemia (male Hb < 120 g/L, female Hb < 110 g/L), renal insufficiency (Cr > 115 micromol/L) and female gender were found to be independent risk factors for mortality in old patients with coronary heart disease post revascularization.</p>
