Objective. To study the effect of Heweianshen decoction (HAD) on orexin-A and cholecystokinin-8 (CCK-8) expression in rat models of insomnia caused by injecting parachlorophenylalanine (PCPA) intraperitoneally.Methods. Fifty male Wistar rats were randomly divided into five groups (10 rats in each group): blank group, model group, and low-, medium-, and high-dose HAD-treated groups. A rat model of insomnia was established by injecting intraperitoneally with PCPA (300 mg/kg body weight). Rats were given normal saline (10 mL/kg) or 5.25, 10.5, and 21 g/kg HAD by intragastric administration once a day for 6 days. After that, the rats were sacrificed to collect the hypothalamus for tests, using radioimmunoassay to detect the expression of orexin-A and CCK-8.Results. Heweianshen decoction reduced the expression of orexin-A and increased the expression of CCK-8 in the hypothalamus of rat model of insomnia.Conclusion. The therapeutic effect of HAD on insomnia is partially attributed to the decreased expression of orexin-A and increased expression of CCK-8.

Abstract BackgroundPlantaginis semen has been widely used as folk medicine and health care food against hyperuricemia (HUA) and gout, but little was known about its pharmacological mechanism. MethodsThe model was established by potassium oxonate intragastric administration. 42 Sprague-Dawley (SD) male rats were randomly divided into the control group, model group, benzbromarone group (10 mg/kg) and three Plantaginis semen groups (n = 7). The Plantaginis semen groups were treated orally with Plantaginis semen at 0.9375, 1.875 and 3.75 g/kg for 28 days. The levels of serum uric acid (UA), creatinine (Cr), triacylglycerol (TG) and tumor necrosis factor-α (TNF-α) were detected using enzyme-linked immunosorbent assay kits. Ultra performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC-Q-TOF/MS) was used as the basis for serum lipidomics analysis, and orthogonal partial least squares discriminant analysis (OPLS-DA) was carried out for the pattern recognition and characteristic metabolites identification. The relative levels of critical regulatory factors of urate anion transporter 1(URAT1) and phosphatidylinositol 3-kinase/ protein kinases B (PI3K/Akt) were determined by quantitative real-time polymerase chain reaction (RT-qPCR). ResultsCompared with the model group, the levels of serum UA, Cr, and TG were significantly (p<0.01) decreased in benzbromarone and three Plantaginis semen groups and the level of serum TNF-α was significantly (p<0.05) decreased in benzbromarone and low dose of Plantaginis semen group. With lipidomics analysis, significant lipid metabolic perturbations were observed in HUA rats, 13 metabolites were identified as potential biomarkers and glycerophospholipid metabolism pathway was mostly affected. These perturbations can be partially restored via treatment of benzbromarone and Plantaginis semen. Additionally, the URAT1 and PI3K/Akt mRNA expression levels were significantly decreased (p<0.05) after treatment with benzbromarone and high dose of Plantaginis semen. ConclusionsPlantaginis semen had significant anti-HUA, anti-inflammatory and renal protection effects and could attenuate potassium oxonate-induced HUA through regulation of lipid metabolism disorder.

Abstract A type of experimental hypersplenism characterized by splenomegaly and thrombocytopenia has been produced in the rat by the repeated intraperitoneal injection of methylcellulose. The urine of these animals was collected and given through a gastric tube to another group of normal rats for a period of 4 weeks. The results were a marked and rapidly developing thrombocytopenia, a delayed but definite anemia with mild reticulocytosis and leukocytosis. When the administration of urine was discontinued, the anemia regressed, but the thrombocytopenia persisted unmodified for 2 weeks. When the urine of hypersplenic rats was again given to this group for 6 additional weeks, it failed to induce anemia or to change the persistent thrombocytopenia. Intragastric administration of urine from normal rats, from rats made anemic by total body radiation and from the hypersplenic group after splenectomy to other groups of normal rats, failed to produce the same changes and only induced moderate leukocytosis. On the basis of these results, it is postulated that in experimental methylcellulose-hypersplenism in the rat there is a humoral factor(s) responsible for the thrombocytopenia, that this humoral factor(s) is eliminated in the urine and that when such urine is given to normal rats, it is responsible for the thrombocytopenia and partially for the anemia that are observed. Such factor(s) are in some important way related to the presence of the spleen.

IntroductionThere are very few comparative controlled trials of risperidone versus olanzapine in manic patients. No previous naturalistic study has compared the efficacy of these two antipsychotics in the natural environment of manic inpatients.ObjectiveThe aim of this retrospective and naturalistic study was to evaluate the efficacy of acute treatment with risperidone vs. olanzapine in Bipolar I manic inpatients.Methods(1) Patients: the study includes all the inpatients diagnosed with bipolar I manic episode (DSM-IV) who were admitted during the years 2009 to 2014. Patients treated with risperidone and olanzapine concomitantly (n = 6) and patients not treated with risperidone or olanzapine (n = 129) were excluded.The patients finally included (n = 183) were separated in two groups:– treated with risperidone (n = 89);– treated with olanzapine (n = 94).(2) The Student-T test was used to compare, between the groups, the mean of scores in YMRS and CGI-S scales and the mean of length of stay.ResultsBaseline characteristics were similar between the groups. The majority of patients were also treated with mood stabilizers (46% with lithium and 45% with valproate).The mean decrease in CGI-S scores from baseline to the day of discharge was significantly (P < 0.003) higher in the risperidone group (−2.81 vs. −2.36). The length of stay was significantly (P < 0.004) lower in the olanzapine group (mean of 23.03 days vs. mean of 30.3).Conclusions(1) The CGI-S scores in manic patients treated with risperidone decreased more than in patients treated with olanzapine during admission. (2) The length of stay was significantly lower in patients treated with olanzapine.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Objective: To evaluate the hyperglycemic effects of Kursi Ziyabet (KZ) tablets on the rat models of diabetes mellitus. Methods: In total, 58 male SD rats were assigned randomly to six groups. All except the normal group were transformed into experimental diabetes mellitus rat models by injecting streptozocin. The hyperglycemic effect and the mechanism of Ziyabet were evaluated by body weight, food and water intake, fasting blood sugar, and related parameters by measuring the oxidative stress-related factors and lipid metabolism indicator level by the corresponding kits using the rat experimental models. Results: Compared with the model group, body weight markedly increased after 3–6 weeks of intragastric administration of Ziyabet tablets ([Formula: see text]), while the water intake significantly decreased in the same period of time ([Formula: see text]). Food intake and fasting blood sugar level also decreased with the high dosage of Ziyabet tablets ([Formula: see text]). There is no significant difference in pancreas’ MDA content of the Ziyabet groups when compared to the model group ([Formula: see text]), while significant increase in SOD level was observed in high-dosage KZ group ([Formula: see text]). The blood serum insulin and free fatty acid level also decreased in the high-dosage KZ group compared with the model group ([Formula: see text]). Conclusion: We conclude that Ziyabet tablets demonstrated protective effects on the diabetic rat models.

Hindbrain administration of MK-801, a noncompetitive N-methyl-d-aspartate (NMDA) channel blocker, increases meal size, suggesting NMDA receptors in this location participate in control of food intake. However, dizocilpine (MK-801) reportedly antagonizes some non-NMDA ion channels. Therefore, to further assess hindbrain NMDA receptor participation in food intake control, we measured deprivation-induced intakes of 15% sucrose solution or rat chow after intraperitoneal injection of either saline vehicle or d(-)-2-amino-5-phosphonopentanoic acid (AP5), a competitive NMDA receptor antagonist, to the fourth ventricular, or nucleus of the solitary tract (NTS). Intraperitoneal injection of AP5 (0.05, 0.1, 1.0, 3.0, and 5.0 mg/kg) did not alter 30-min sucrose intake at any dose (10.7 ± 0.4 ml, saline control) (11.0 ± 0.8, 11.2 ± 1.0, 11.2 ± 1.0, 13.1 ± 2.2, and 11.0 ± 1.9 ml, AP5 doses, respectively). Fourth ventricular administration of both 0.2 μg (16.7 ± 0.6 ml) and 0.4 μg (14.9 ± 0.5 ml) but not 0.1 and 0.6 μg of AP5 significantly increased 60-min sucrose intake compared with saline (11.2 ± 0.4 ml). Twenty-four hour chow intake also was increased compared with saline (AP5: 31.5 ± 0.1 g vs. saline: 27.1 ± 0.6 g). Furthermore, rats did not increase intake of 0.2% saccharin after fourth ventricular AP5 administration (AP5: 9.8 ± 0.7ml, vs. saline: 10.5 ± 0.5ml). Finally, NTS AP5 (20 ng/30 nl) significantly increased 30- (AP5: 17.2 ± 0.7 ml vs. saline: 14.6 ± 1.7 ml), and 60-min (AP5: 19.4 ± 0.6 ml vs. saline: 15.5 ± 1.4 ml) sucrose intake, as well as 24-h chow intake (AP5: 31.6 ± 0.3 g vs. saline: 26.1 ± 1.2 g). These results support the hypothesis that hindbrain NMDA receptors participate in control of food intake and suggest that this participation also may contribute to control of body weight over a 24-h period.

Abstract Objective: to observe the effects of moxibustion on histomorphological changes of gastric mucosa, as well as on serum IL-6、IL-8、TNF-α,Hp IgG、CD3+、CD4+、CD8+ in helicobacter pylori (Hp) infected rats, so that to better understand how the moxibustion repairs the Hp- induced gastric mucosal injury. Methods: 40 SD rats were randomly assigned to four groups: group A (blank control), group B (Hp infection model), group C (moxibustion plus model), group D (electro-acupuncture plus model), 10 for each group. The “NaHCO3 plus Indometacin and Hp intragastric administration” method was employed to make gastritis model. Acupoints selected for “repair” purpose were Zu San Li (ST36), Zhong Wan (CV12), Guan Yuan (RN4), Pi Shu (BL20), Wei Shu(BL21). The histomorphological changes of gastric mucosa in rats were observed under light microscope after HE stain; IL-6, IL-8, TNF-α, Hp IgG values were evaluated by ELISA method; values of CD3+、CD4+、CD8+、CD4+/CD8+ were measured by flow cytometry method. Results: compared with group A, the values of IL-6, IL-8, TNF-α, Hp IgG and CD8+ in group B were increased(P<0.01), whereas the values of CD3+、CD4+、CD4+/CD8+ were decreased(P<0.01). Compared with group B, the values of IL-8(P<0.05),TNF-α(P<0.05), IL-6(P<0.01), Hp IgG(P<0.01) and CD8+ (P<0.05) in group C were decreased, whereas the values of CD3+(P<0.05),CD4+(P<0.05),CD4+/CD8+ (P<0.05) were increased, meanwhile such values in group D had no significant changes. Compared with group D, the values of IL-6(P<0.05),IL-8 (P<0.05)and Hp IgG (P<0.01)in group C were decreased, whereas CD4+/CD8+(P<0.05)were increased, all those changes had statistical significance. Conclusion: the preventive and therapeutic effects of moxibustion on Hp related gastritis might be realized by two ways- to inhibit the secretion of proinflammatory cytokines such as IL-6, IL-8 and TNF-α, or to regulate the production of immune factors (such as up-regulation of CD3+, CD4+ and down-regulation of CD8+).

Allergic rhinitis (AR) is a type of nasal mucosal inflammation. Lactobacillus plays a critical role in maintaining micro-ecological balance. This study aims to detect its effects on IL-4, TNF-α, Th1 and Th2 in AR sprapue-dawley (SD) rat after lactobacillus intervention. Ovalbumin (OVA) allergic AR SD rat model was established and assigned into model group, experimental group and blank group followed by analysis of Nasal mucosa under the microscope, IL-4 and TNF-α level by ELISA and immunohistochemistry assay, and Th1 and Th2 cells in spleen by flow cytometry. AR symptom in experimental group was significantly severe compared to blank group, but relative better compared to model group (p < 0.05). Nasal mucosal hyperemia and inflammation was significantly ameliorated in experimental group with significantly increased Th1 cells and Th1/Th2 ratio and decreased Th2 cells compared to model group (p < 0.05). In conclusion, Lactobacillus intervention reduced IL-4 and TNF-α expression in serum and tissue and ameliorated the inflammation in AR rat.

Increased Hcy has a toxic effect on nerve cells and can cause hippocampal death and directly damage the body’s cognitive function and memory ability, leading to the occurrence of vascular dementia. Hcy predicts vascular disease and might be a basis for clinical judgment. This article provides a new basis for the prevention and treatment of this disease by exploring the mechanism of action of memantine hydrochloride in diabetic vascular dementia. After grouping, mice walked through the Morris water maze to record the escape latency, and measured the Hcy level of the mice by high performance liquid chromatography. Observing the volume of brain atrophy in mice. GFAPT, APP, and CHAT level in mouse hippocampus was assessed by IHC and CHAT mRNA was detected by RT-PCR. Escape latency, Hcy level (11.46 ±0.74) yiimmol/L, brain atrophy volume (25.21 ±1.21) mm3, number of APP positive cells (46.7003±3.2431), number of GFAP positive cells (21.4000 ± 1.8127) were all significantly lower than those of model group. The positive rate of CHAT and the amount of CHAT mRNA in the memantine hydrochloride group was significantly elevated (P < 0.05) with higher CHAT mRNA than model group and lower than blank group (P < 0.05). Memantine hydrochloride could reduce the level of Hcy in mice, improve the cognitive function of mice with diabetic vascular dementia by improving the number of GFAP and CHAT positive cells in hippocampus and cortex, and increasing the amount of CHAT mRNA in brain tissue.
