Cold Coagulation

In this study, we try to evaluate the effects of acupuncture stimulation with different amounts at Sanyinjiao (SP6) on uterine contraction and uterus microcirculation in rats with dysmenorrhea of cold coagulation syndrome and to explore whether there is direct relativity between “De qi” and needle stimulus intensity. Diestrus female rats were randomly divided into 4 groups, including saline control group, model control group, “A” stimulus group (with strong stimulus), and “B” stimulus group (with weak stimulus). We found that dysmenorrhea rats of the cold coagulation syndrome present a high intensity in uterine tension and high contraction of microvascular diameter. Acupuncture applied with two different stimuli could relieve the symptoms, but, compared with “B” stimulus, “A” stimulus leads to better outcomes on reducing uterine contraction and increasing diameter of uterine microvascular; moreover, hand manipulation during needling mediates the curative effect on the microvascular diameter. Our finding indicates that using thick needles and deep insertion with hand manipulation are more effective and achieve desired level of “De qi” in dysmenorrhea rats.

Abstract Background: Premature ovarian failure is among the most important side effects of chemotherapy during reproductive period. Preserving ovarian function is gradually gaining importance during oncologic treatment. The present study aims to investigate the potential of melatonin to protect from cisplatin-induced ovarian toxicity in rats. Twenty nine female rats were divided to three groups: Saline control group (Group 1), cisplatin group (Group 2), and cisplatin+melatonin group (Group 3). While the rats in Groups 2 and 3 were administered 5 mg/kg single dose of cisplatin via intra-peritoneal (IP) route, the rats in Group 3 were started on melatonin (20 mg/kg IP) before cisplatin administration and continued during 3 consecutive days. Ovaries were removed one week after cisplatin administration in all groups. Blood samples were obtained before the rats were decapited. Histological evaluation, follicle count, and classification were performed. TAp63 mRNA expression was evaluated using mRNA extraction and real-time polymerase chain reaction (PCR) method. Serum estradiol (E2) and anti-mullerian hormone (AMH) values were measured with enzyme immune-assay technology. Results: While primordial follicles were seen to decrease in Group 2 as compared to Group 1 (p:0.023), primordial follicle count was observed to be preserved significantly in melatonin group as compared to Group 2 (p:0.047). Moreover, cisplatin-induced histo-pathological morphology was preserved in favor of normal histology in melatonin group. A significant difference was not observed between groups with regard to mean serum AMH and E2 values (p:0.102 and p:0.411, respectively). While TAp63 gene expression significantly increased in Group 2 as compared to control group (p:0.001), we did not detect a statistically significant difference in cisplatin+melatonin group, although gene expression decreased (p:0.34). Conclusion: We conclude that concurrent administration of melatonin and cisplatin may protect from ovarian damage.

Model Similarity

This study was designed to determine if observing a similar or dissimilar model who makes varying self-efficacy statements influences an observer's efficacy expectations and, in turn, muscular endurance performance. Females (N = 150) were randomly assigned to groups in a 2 × 4 × 3 (model similarity by model talk by trials) factorial design or to a no-model control group. Model similarity was manipulated by having subjects view a female described as a nonathlete (similar) or a male described as a varsity track athlete (dissimilar). The four levels of model talk included: a positive self-talk model who performed and made positive self-efficacy statements, a negative self-talk model who made negative self-efficacy statements, an irrelevant-talk model who made statements unrelated to self-efficacy, and a no-talk model who remained silent throughout the performance. Self-efficacy measures were assessed in addition to performance on three trials of a muscular endurance task. Results revealed that similar model subjects extended their legs significantly longer than dissimilar model and control subjects. Moreover, the similar-positive-talk and similar-no-talk groups performed significantly better than the dissimilar-positive-talk, dissimilar-negative talk, dissimilar-no-talk, and the no-model control groups. Subject self-efficacy, however, was not found to be the major mediating variable affecting these performance changes.

Persimmon has good health function. To further investigate the antioxidant function in vivo, we set up a model mice with ionizing radiation. IRC mice were divided randomly into six groups, Blank control group, Model control group, VE control group, Low dosage group (G1), Middle dosage group (G2) and High dosage group (G3) respectively. Orally given persimmon extract for 35 days, mice were treated with γ-rays. Our results indicated that pervious administration of the persimmon extraction obviously increased the liver index of the mice. And pathological inspection by microscope suggested that orally given persimmon extraction obviously protected the liver cells of the mice. Further analysis demonstrated that persimmon extraction decreased the MDA content, and increased the SOD and GSH-PX activity in both the serum and the liver in the mice after the Ionizing radiation. Our results suggested the protection role of persimmon extraction by inhibiting the oxidation reaction in vivo.

Based on previous studies about microflora regulation and immunity enhancement activities of polysaccharides from Codonopsis pilosula Nannf. var. modesta (Nannf.) L. T. Shen (CPP), there is little study on intestinal mucosal immunity, which is a possible medium for contacting microflora and immunity. In the present study, the BALB/c mice were divided into five groups (eight mice in each group), including a normal group (Con), a model control group (Model), and model groups that were administered CPP (50, 100, 200 mg/kg/d) orally each day for seven days after intraperitoneal injection of 60 mg/kg BW/d cyclophosphamide (CP) for three days. CPP recovered the spleen index and restored the levels of IFN-γ, IL-2, IL-10, as well as serum IgG. In addition, it elevated ileum secretory immunoglobulin A (sIgA), the number of Lactobacillus and acetic acid content in cecum. These results indicated that CPP plays an important role in the protection against immunosuppression, especially mucosa immune damage, and the inhibition of pathogenic bacteria colonization, which could be considered a potential natural source of immunoregulator.

Objective. The blood of cancer patients is in a state of hypercoagulability, easily leading to thrombosis. Anemia is also a complication of tumors. Anemia and thrombosis affect the treatment of tumor patients. Methods. Ginsenosides Rb were extracted from the stems and leaves of American ginseng using water-saturated ethanol and ethyl acetate in silica gel column. Tumor mice model was established by injecting H22 hepatocellular carcinoma cells into the axilla of mice. Mice were randomly divided into 6 groups: normal control group, model control group, positive control group, low dose group (7 mg/kg), middle dose group (14 mg/kg), and high dose group (35 mg/kg). After 18 days, the blood was obtained by picking the eyeball of mice. The levels of red blood cells (RBC), hemoglobin (HGB), neutrophils/lymphocytes radio (NLR), platelets (PLT), platelet distribution width (PDW), fibrinogen (FIB), and D-Dimer (D-D) were measured and compared in each group of mice. Results. The content of obtained ginsenosides Rb reached 90.05%. This extraction process was simple and reliable. Middle dose of ginsenosides Rb could significantly increase RBC and HGB levels (P<0.05). Moreover, ginsenosides Rb could significantly reduce NLR, PLT, PDW, FIB, and D-D (P<0.01). Conclusion. ginsenosides Rb could significantly improve anaemia and hypercoagulation of blood in cancer mice. Ginsenosides Rb are a potential anticoagulant and antianemia drug in treating cancer.

Triamcinolone acetonide acetate (TAA)-loaded nanostructured lipid carriers (NLC) were prepared to investigate their transdermal absorption in vitro and establish a diabetic retinopathy (DR) rat model. To evaluate the effect of triamcinolone acetonide-loaded nanoparticle capsules on improving the structure of the retina and pancreas, we measured blood glucose levels and investigated the pathological changes in the retina and pancreas. The effect of triamcinolone acetonide-loaded nanoparticle capsules on the morphology of the retina and pancreas of the rats with DR was determined and compared among the normal group, model control group, positive control group, and triamcinolone acetonide-loaded nanoparticle group. After treatment with triamcinolone acetonideloaded nanoparticle capsules for 2 months, the blood glucose and glycosylated hemoglobin levels were significantly lower (P < 0.01) and the pathological changes were less severe in the triamcinolone acetonide-loaded nanoparticle group than in the model control group. In addition, the arrangement of the photoreceptor cell layers in the retina was organized, intracellular and extracellular edema in each layer was reduced compared with that in the model control group, the capillary lumen was not occluded, and the peripheral cells were slightly edematous in the triamcinolone acetonide-loaded nanoparticle group. Triamcinolone acetonide-loaded nanoparticle capsules could effectively reduce the blood glucose and glycosylated hemoglobin levels and improve the structure of the retina and pancreas in the rats with DR.

Background. Deqi sensation is a complex but an important component for acupuncture effect. In this study, we tried to observe the relationship between Deqi and skin temperature changes and whether there was some relativity between Deqi and needle stimulations on cold congealing and dysmenorrhea rat model. Thirty-two female Sprague Dawley (SD) rats were randomly divided into four groups (Saline Control Group, Model Group, Group A with strong stimulation, and Group B with small stimulation). Group A and Group B were performed with different stimulations. We found that, compared with saline control group, model group, and Group B, Group A showed that the skin temperature changes on right acupoint SP6 and SP10 increased significantly at 5 min–10 min interval. The skin temperature changes on left SP6 decreased at instant–5 min interval. The skin temperature changes on right SP10 decreased significantly at instant–5 min interval and 10 min–20 min interval. Thermogenic action along Spleen Meridian of Foot Greater Yin was manifested as simultaneous skin temperature increase on right SP6 and SP10 at 5 min–10 min interval after needling SP6, which was helpful to illustrate the relationship between the characteristic of Deqi and needle stimulations.

Objective. To evaluate the hypolipidemic activity and antiatherosclerotic effect of polysaccharide ofPolygonatum sibiricum(PPGS), which is a kind of Chinese herbal medicine using the rhizome part of the whole herb.Materials and Methods. Thirty rabbits were divided into normal control group, model control group, and PPGS subgroups of 0.8, 1.6, and 3.2 mL/kg/day under random selection. In atherosclerosis model, the effects of PPGS on diverse blood lipids, foam cells number, and aortic morphology were evaluated. In the primary culture of endothelial cells (ECs), the activities of PPGS on both ECs proliferation and ECs injury were studied as well.Results. In atherosclerosis model, the hypolipidemic activities of PPGS were mainly focused on TC, LDL-C, and Lp(a). All changes on these factors were statistically significant compared with model group (P< 0.01), except TG and HDL-C. The intimal foam cell number of PPGS subgroups (0.8, 1.6, and 3.2 mL/kg/day) was significantly reduced than model control (P< 0.01). In the primary culture of endothelial cells (ECs), PPGS showed no effect on cell proliferation but preferred to protect EC from injury and apoptosis induced by H2O2and lipopolysaccharide (LPS).Discussion and Conclusion. The antiatherosclerotic effect of PPGS may be supported by its hypolipidemic activities, improving aortic morphology, and reducing foam cells number and ECs injury.

The purpose of this study was to explore the effect of the traditional Chinese medicine Fuyou formula on precocious puberty (PP). The Fy formula may exert an effect in female rats with PP and GT-7 cells through the GPR54/GnRH signaling pathway. To confirm the effect of the Fy formula on PP through the GPR54/GnRH signaling pathway, we first treated GT1-7 cells with the Fy formula and observed changes in the expression of related genes and proteins and in GnRH secretion. Then, we randomly divided young female Sprague-Dawley rats into the control group, model group, leuprorelin group and the Fy formula group. A PP model was established by injection of danazol on postnatal day 5, and the Fy formula was administered on PND15. The time of vaginal opening, the wet weights of the ovary and uterus, serum hormone levels and the expression of hypothalamic-related genes were observed. We found that the Fy formula delayed vaginal opening, decreased the wet weights and coefficients of the ovary and uterus, decreased the levels of serum hormones (E2, follicle-stimulating hormone and luteinizing hormone) and the cellular GnRH level, and downregulated the gene expression of Kiss1, GPR54 and GnRH in the hypothalamus and the gene and protein expression of GPR54 and GnRH in GT1-7 cells. In conclusion, the Fy formula may alleviate PP via the GPR54/GnRH signaling pathway.
