The aim is to explore the effect of acupuncture on Th1, Th2 cytokines in rats of implantation failure. Early pregnant rats were randomized into normal group (N), implantation failure group (M), acupuncture group (A), progestin group (H). The model was established with mifepristone. Samples of serum, endometrium were collected on Day 5, 6 and 8 of pregnancy. Compared with group M, the number of embryos was significantly higher in groups N, A and H; IL-1β, IL-2 protein in serum and endometrium were significantly lower in groups N, A and H, while IL-4, IL-10 were significantly higher in groups N, A and H; the endometrial IL-2, IL-4 mRNA were significantly lower in groups N, A and H, while IL-1β, IL-10 mRNA were significantly higher in groups N, A and H. Acupuncture could improve the poor receptive state of endometrium due to mifepristone by promoting Th2 cytokines secretion and inhibiting Th1 cytokines to improve blastocyst implantation.

Abstract Objective The aim of this study is to investigate the effect of irisin on leukemia inhibitory factor (LIF) and integrin αvβ3 in implantation failure uterus. Methods Early pregnant rats were randomly divided into normal group (N), mifepristone treated group (M), irisin group (I) and progestin group (P). The implantation failure model was established using mifepristone. Second, we evaluated the average number of embryos and detected the expression of LIF and integrin αvβ3 protein and mRNA in endometrium. Results Compared with group M, the average number of embryos was significantly higher in group N, P and I, the expression of LIF and integrin αvβ3 in endometrium was significantly higher in group N, P and I. Conclusion Irisin could improve the poor receptive state of endometrium by promoting LIF and integrin αvβ3 secretion to improve blastocyst implantation in rats of implantation failure.

The present study was designed to investigate the efficacy and mechanism of acupuncture treatment on embryo implantation failure in rats. The pregnant rats were randomized into normal group (N), implantation failure group (M), acupuncture treatment group (A), and progestin treatment group (W). The embryo implantation failure model was established by mifepristone. Efficacy of acupuncture treatment was evaluated by the number of implanted embryos. The expression of CCL2 and CXCL8 and the subset of uterine natural killer cells in the endometrium were detected. We demonstrated that the number of implanted embryos was dramatically reduced after mifepristone (M group) treatment, while the acupuncture (A group) and progestin (W group) treatments significantly rescued impaired embryo implantation. The protein and mRNA expressions of CCL2 and CXCL8 were significantly reduced by mifepristone treatment, but the attenuated expression of CCL2 and CXCL8 was markedly reversed by acupuncture or progestin treatment. More importantly, acupuncture and progestin could markedly increase the subset of uNK cells in rats with embryo implantation failure. These evidences suggest that acupuncture is able to modulate the endometrial immune microenvironment and thus improve embryo implantation in pregnant rats, which provides solid experimental evidence for the curative effect of acupuncture treatment on infertility.

OPN is essential for blastocyst implantation and placentation. Previous study found that miR181a was increased while miR181b was downregulated in endometrium during decidualization. However, the information regarding their effects on decidualization in human endometrium is still limited. Here, we report a novel role of OPN and miR181b in uterine decidualization and pregnancy success in humans. The expression of OPN was high in endometrium in secretory phase and in vitro decidualized hESC, whereas miR181b expression was low in identical conditions. Further analysis confirmed that OPN expression was upregulated by cAMP and C/EBPβ signal pathway, while downregulated by miR181b. Increased OPN expression could promote the expression of decidualization-related and angiogenesis-related genes. Conversely, the processes of decidualization and angiogenesis in hESC were compromised by inhibiting OPN expression in vitro. OPN expression was repressed in implantation failure group when compared with successful pregnancy group in IVF/ICSI-ET cycles. These findings add a new line of evidence supporting the fact that OPN is involved in decidualization and pregnancy success.

AbstractDilated cardiomyopathy (DCM) is a primary myocardial disease, the pathology of which is left ventricular or biventricular dilation and impaired myocardial contractility. The clinical and pathological diagnosis of DCM is difficult, and other cardiac diseases must be ruled out. Several studies have reported pathological findings that are characteristic of DCM, including cardiomyocyte atrophy, nuclear pleomorphism, and interstitial fibrosis, but none of these findings are DCM-specific. In this study, we examined the morphological differences in the intercalated discs (ICDs) between three groups of patients, a DCM group, a chronic heart failure group, and a control group. A total of 22 autopsy cases, including five DCM cases, nine CHF cases and eight control cases, were retrieved from the archives of the Department of Pathology at Akita University, Japan. The morphological differences were examined using multiple methods: macroscopic examination, light microscopy, immunohistochemistry, electron microscopy, and gene expression analyses. We observed disorganized ICDs, clearly illustrated by N-cadherin immunostaining in the DCM group. “Reduction of N-cadherin immunostaining intensity” and “ICD scattering” was DCM-specific. The results suggest that disorganized ICDs contribute to the development of DCM, and that N-cadherin immunostaining is useful for determining the presence of disorganized ICDs and for the pathological diagnosis of DCM.

AbstractMucosal lesions of paracoccidioidomycosis (PCM) are frequently described and clinically important. Macrophages are classified as M1 or M2. M1 are proinflammatory and M2 are related to chronicity. Dectin-1 recognizes β-glucan and plays an important role against fungal cells. The objective was to verify the presence of M1, M2, and dectin-1 and a possible correlation with Th1/Th2 cytokines in mucosal PCM lesions. In sum, 33 biopsies of oral PCM were submitted to histological and immunohistochemistry analysis, and positive cells were quantified. Eleven biopsies were characterized by compact granulomas (G1), 12 with loose granulomas (G2), and 10 with both kind of granulomas (G3). pSTAT-1 was equally increased in the three groups. G1 was characterized by an increased number of CD163+ macrophages. G2 presented similar number of arginase 1, iNOS, and CD163 expressing cells. G3 presented an increased number of cells expressing arginase 1 and CD163 over iNOS. G1 and G3 presented high number of cells expressing interferon (IFN)-γ; interleukin (IL) 5 was increased in G2 and G3; the expression of IL10 was similar among the three groups, and the expression of tumor necrosis factor (TNF)-α was higher in G3. G1 correlates to Th1 cytokines and pSTAT-1 and G2 correlates to Th2 cytokines. G3 presents both kinds of cytokines. We could not associate the expression of arginase-1, CD163, iNOS, and dectin-1 with the pattern of cytokines or kind of granuloma.

SUMMARY Plasma luteinizing hormone (LH) concentrations were already lower on Day 2 of pregnancy than at the same time after the preceding ovulation in the non-pregnant rat, and fell progressively up to Day 16 of pregnancy. No evidence was obtained of any increase at the time when the ovulatory surge of LH would have occurred if the animal had not become pregnant. Pituitary LH concentration was lower in mated rats on the morning of Day 0 of pregnancy than in unmated controls on the morning of the day of oestrus. Subsequently it increased slowly to reach a level higher than at any stage of the oestrous cycle by Day 8 of pregnancy and remained high until at least Day 16 of pregnancy. Peripheral plasma oestradiol concentration increased late on Day 2 of pregnancy and was still raised on Day 4 but was never more than about one fourth of the peak concentration seen on the morning of prooestrus during the oestrous cycle. There were similar changes in plasma LH and oestradiol concentrations in the 48 h after a single injection of 2·5mg progesterone on the morning of the day of dioestrus, a procedure that delays ovulation by 1 or 2 days. Administration of a synthetic progestational compound (medroxyprogesterone acetate) to pregnant rats delayed blastocyst implantation and the delay was associated with a marked decrease in peripheral plasma LH to levels below those of normal pregnancy.

AbstractObjective:The Composite Index of Anthropometric Failure (CIAF) can only be applied to children under 5 years of age and does not contemplate obesity. The aim of this study was to propose an Extended CIAF (ECIAF) that combines the characterization of malnutrition due to undernutrition and excess weight, and apply it in six Argentine provinces.Design:ECIAF excludes children not in anthropometric failure (group A) and was calculated from a percentage of children included in malnutrition categories B: wasting only; C: wasting and underweight; D: wasting, stunting and underweight; E: stunting and underweight; F: stunting only; Y: underweight only; G: only weight excess; and H: stunting and weight excess.Setting:Cross-sectional study conducted in Buenos Aires, Catamarca, Chubut, Jujuy, Mendoza and Misiones (Argentina).Participants:10 879 children of both sexes aged between 3 and 13·99.Results:ECIAF in preschool children (3 to 4·99 years) was 15·1 %. The highest prevalence was registered in Mendoza (16·7 %) and the lowest in Misiones (12·0 %). In school children (5 to 13·99 years) ECIAF was 28·6 %. Mendoza also recorded the highest rate (30·7 %), while Catamarca and Chubut had the lowest values (27·0 %). In the whole sample, about 25 % of the malnutrition was caused by undernutrition and 75 % by excess weight.Conclusions:The ECIAF summarizes anthropometric failure by both deficiency and excess weight and it highlights that a quarter of the malnutrition in the Argentine population was caused by undernutrition, although there are differences between Provinces (P < 0·05). ECIAF estimates are higher than those of CIAF or under-nutrition.

Acupuncture has been suggested as helpful in reflex sympathetic dystrophy (RSD), but no controlled study has yet been published. The hypothesis of this randomised, double-blind, sham-controlled trial, therefore, was that traditional Chinese acupuncture improves subjective as well as objective signs in this condition. Patients were included when suffering from clinically and scintigraphically confirmed acute RSD of the upper or lower limb, with a history between one and four months. They were randomly assigned to either traditional acupuncture (group A) or sham acupuncture (group S). Treatments were applied five times a week for three weeks, each session lasting for 30 minutes. Both groups received identical standard treatments in addition. The primary outcome variable had been pre-defined to be pain, as measured by visual analogue scale assessed before each treatment. Subjective success was also recorded by the patients on a rating scale. Due to force of circumstances, only 14 patients were entered into the study, therefore no test statistics could be performed and the data was evaluated descriptively. At baseline, pain was almost identical in both groups. During the course of the study, patients in group A demonstrated a more pronounced reduction of pain: 28.6% ± 1.9 vs 17.9% ± 2.4 (Mean ± SEM). Similarly, subjective success was rated to favour traditional acupuncture. It is concluded that acupuncture may be useful in the management of pain in patients with acute RSD, but that the present results are not conclusive. Larger, rigorous studies are required to answer the question.

Background Migraine is one of the most common types of headache, with significant socioeconomic effects. Prophylactic drugs are used to prevent migraine headaches but are unpromising. Objective To assess the effects of adding acupuncture to conventional migraine prophylaxis. Methods One hundred patients with migraine (41 male, 59 female), in whom prophylactic drugs had not produced a fall of at least 50% in the number of attacks, entered the study. The patients were randomised into two groups, sham and true acupuncture. The patients in both groups continued their prophylactic treatment and received 12 sessions of either true or sham acupuncture. Each session was 30 min and was repeated three times a week. The number of headaches in the two groups was compared at baseline, and at the end of four successive months. Results There was no significant difference in the frequency of attacks between the two groups before intervention. After 1 month, the frequency of attacks each month decreased from 5.1 (0.8) to 3.4 (1.2) in the true acupuncture group, and from 5.0 (0.8) to 4.4 (1.1) in the sham acupuncture group (a significant difference, p<0.001). The frequency continued to decrease in month 2 but increased in months 3 and 4; however, it was still significantly lower than baseline, and the difference remained significant after month 4. Conclusions Acupuncture is applicable as an adjunct to prophylactic drugs in migraineurs in whom the number of attacks does not fall with prophylactic medication.
