Adenylyl cyclase (AC)-cyclic adenosine monophosphate (cAMP)-cAMP-dependent protein kinase A (PKA) cascade is considered to be associated with the pathogenesis and treatment of depression. The present study was conducted to explore the role of the cAMP cascade in antidepressant action of electroacupuncture (EA) treatment for chronic mild stress (CMS)-induced depression model rats. The results showed that EA improved significantly behavior symptoms in depression and dysfunction of AC-cAMP-PKA signal transduction pathway induced by CMS, which was as effective as fluoxetine. Moreover, the antidepressant effects of EA rather than Fluoxetine were completely abolished by H89, a specific PKA inhibitor. Consequently, EA has a significant antidepressant treatment in CMS-induced depression model rats, and AC-cAMP-PKA signal transduction pathway is crucial for it. Copyright © 2012 Jian-hua Liu et al.

To prove analgesia and sedative effect of adjuvant anesthesia with magnetic auricular point-sticking on abdominal gynecological operation and its effect on postoperative recovery of body function. Ninety-two patients with abdominal gynecological operation were randomly divided into 3 groups. The auricular point-sticking group (APS group, n=31) was pasted and pressed by plasters with magnetic beads at bilateral Shenmen, Pizhixia (subcortex), Zigong (uterus) and Penqiang (pelvic cavity), etc. the night before operation. The placebo group (n=31) was pasted by plasters without magnetic beads. The blank group (n=30) was given no intervention. The mental and gastrointestinal functional changes before and 3 days after the operation were observed. As compared with those in the control group and the blank group, the postoperative score of Self rating Anxiety Scale (SAS) was less (25.5 +/- 0.81 vs. 28.9 +/- 3.19, 28.3 +/- 2.36, both P < 0.01), with lower-dose of Innovar [(2.5 + 1.1) mL vs. (3.4 + 1.8) mL, (3.2 + 1.6) mL, both P < 0.05], earlier exsufflation after the operation [(34.2 + 12.1) h vs. (46.3 + 10.9) h, (43.2 + 14.8) h, both P < 0.01] and higher level serum of beta-endorphin before and after the operation in the APS group (all P < 0.05). The magnetic auricular point-sticking has sedative, analgesic and function-regulating effects on the abdominal gynecological operation.

STUDY QUESTIONIs there a molecular link between Wnt signaling in fallopian tube inflammation and ectopic tubal implantation?SUMMARY ANSWEREnhanced beta-catenin expression, reduced E-cadherin expression and glycogen accumulation in the tubal epithelia and hyperplasia in tubal arteries were found in ectopic tubal pregnancy, consistent with the effects induced by Wnt signaling and inflammation.WHAT IS KNOWN ALREADYChronic inflammation caused by infection can alter gene expression in the fallopian tube cells possibly leading to the development of ectopic pregnancy. Knockout mouse models have shown a relationship between Wnt/beta-catenin signaling and predisposition to tubal ectopic pregnancy.STUDY DESIGN, SIZE, DURATIONWomen with ectopic tubal pregnancy (n = 18) were included in the case group, while women with chronic salpingitis (n = 13) and non-pregnant women undergoing sterilization procedures or salpingectomy for benign uterine disease (n = 10) were set as the controls. This study was performed between January 2012 and November 2012.PARTICIPANTS/ MATERIALS, SETTING, METHODSThe ampullary segments of fallopian tubes were collected from patients. Tissues of tubal pregnancy were separated into implantation sites and non-implantation sites. Beta-catenin and E-cadherin expression were determined using immunohistological and immunofluorescence staining. Glycogen production was measured with periodic acid Schiff by staining. The diameter and wall thickness of tubal arteries were evaluated by histological analysis method.MAIN RESULTS AND THE ROLE OF CHANCEImmunohistological staining revealed that beta-catenin protein expression was 100% positive in the ectopic pregnant and inflamed tubal tissues, and the staining intensity was significantly higher than in non-pregnant tubal tissues. In contrast, E-cadherin expression was reduced in ectopic pregnant fallopian tubes, possibly as a consequence of increased Wnt signaling. Moreover, glycogen accumulated in the tubal cells, and hyperplasia was observed in the tubal arteries with ectopic pregnancy, which is consistent with the effects induced by Wnt signaling and inflammation. All these changes could create the permissive environment that promotes embryos to ectopically implant into the fallopian tube.LIMITATIONS, REASONS FOR CAUTIONThis finding requires a further confirmation about what activates Wnt signaling in ectopic tubal pregnancies. Also, it is generally recognized that Chlamydia infection is associated with ectopic pregnancy, and disturbs tubal epithelia via the Wnt signaling. However, the infection type in the samples used was salpingitis.WIDER IMPLICATIONS OF THE FINDINGSA better understanding of the underlying mechanisms leading to ectopic pregnancies may contribute to our knowledge of the pathogenesis of tubal disorders and infertility and to the prevention of tubal ectopic pregnancy. © The Author 2013.

Background The physio-chemical properties of blood contacting biomaterials play an important role in determining their hemocompatibility. It is shown in literature that surface roughness and porosity have significant effect on hemocompatibility. In this study, we use a biocompatible, low thrombogenic nanocomposite polymer called POSS-PCU to test this hypothesis: would porosity compromise the hemocompatibility of POSS-PCU. We compared the hemocompatibility of POSS-PCU films of various pore sizes with PTFE, which is a commercially available material used in most blood contacting devices. Methods Sterilized POSS-PCU films with different size pores were prepared as samples and porous PTFE film were selected as control. And all samples were subjected to SEM for topograpgy, mechanical test for characterization and hemocompatibility tests to evaluate contact activation, platelet adhesion and activation, as well as whole blood clotting response to the samples. Results WCA significantly increased with the pore size of POSS-PCU film, whereas both tensile stress and strain decreased significantly as the sizes of pores increased. However, when compared to PTFE film with same size pores, POSS-PCU films showed both higher tensile stress and strain. Pore size had little impact over POSS-PCU's surface chemistry groups as tested by FTIR analysis. Contact activation and platelet adhesion essay also showed no significant difference between different POSS-PCU samples. However, in whole blood reactions, POSS-PCU with pores size around 2-5 μm showed higher BCI than plain films and those with pores size around 35-45 μm. POSS-PCU showed lower thrombogencity and higher hemocompatibility comparing with porous PTFE on the aspects of platelet activation, adhesion and whole blood reaction. Summary and conclusions POSS-PCU polymer films as a biomaterial in chronic blood contacting implants show significant lower thrombogencity and higher hemocompatibility than porous PTFE film. It is desirable as a coating or covering material in small diameter stents for treating cardiovascular diseases, cerebral vascular diseases and peripheral arterial diseases. © 2015 Published by Elsevier Ltd.

To explore an optimum method on postoperative recovery of general-anesthesia gynecological laparoscopic surgery. One hundred and twenty cases of gynecological laparoscopic surgery were randomly divided into three groups, 40 cases in each one. The sensitive points of bilateral Shenmen (TF4), Zigong (TF2), Wei (CO4), Dachang (CO7) and so on were selected in all three groups one night before the surgery. The sticking with magnetic beads was applied in the group A. The magnetic beads were in-pair stuck at front-back corresponding location of both ears in the group B. The same-appearance plaster was put at the corresponding acupoints in the group C. The intubation anesthesia was applied in all three groups and postoperative recovery of gynecological laparoscopic surgery was observed. The postoperative visual analogue scale (VAS) was (1.77 +/- 1.65) in the group A and (1.80 +/- 1.96) in the group B, which was both lower than (2.62 +/- 1.46) in the group C (both P < 0.01). The occurrence rate of nausea and vomiting was 25.0% (9/36) in the group A and 20.0% (8/40) in the group B, which was both lower than 50.0% (19/38) in the group C (both P < 0.01). The recovery of borborygmus on postoperative 1st and 3rd day in the group A and B was faster than that in the group C (both P < 0.05), while time of fart and defecation in the group A and B was earlier than that in the group C (both P < 0.05). The score of state-trait anxiety inventory in the group A and B was lower than that in the group C (both P < 0.05), but the differences of each item between the group A and B were not obvious (both P > 0.05). The auricular point sticking could support analgesia of general-anesthesia gynecological laparoscopic surgery, which could relieve anxiety mood, reduce occurrence of nausea and vomiting and improve function of stomach and intestine to benefit postoperative recovery. However, the effect of in-pair sticking of auricular point with magnetic beads at front-back acupoints was not obviously strengthened.

To assess the clinical efficacy of acupuncture and moxibustion on depression in view of the outcome indicators of the patient subjective reports. One hundred and sixty-three cases of depression being in compliance with the inclusive standards were randomized into a soothing-liver and regulating-mind group, an acupoint-shallow-puncturing group and a non-acupoint-shallow-puncturing group. In the soothing-liver and regulating-mind group, the conventional acupuncture was applied to the four-gate points [Hegu (LI 4) and Taichong (LR 3)], Baihui (GV 20) and Yintang (EX-HN 3), the direct moxibustion with moxa cone was applied to the four-flower points [Geshu (BL 17), Danshu (BL 19)]. Finally, the intradermal needling was used at Xinshu (BL 15) and Ganshu (BL 18). In the acupoint-shallow-puncturing group, the acupoints selected were same as those in the soothing-liver and regulating-mind group. But the needle insertion was shallower and the time of moxibustion was shorter. In the non-acupoint-shallow-puncturing group, the spots that were 10 mm lateral to those acupoints in the soothing-liver and regulating-mind group were selected. The operation was same as that in the acupoint-shallow-puncturing group. The treatment was given twice a week in three groups. Totally, 12 weeks of treatment were required. The score of symptom checklist 90 (SCL-90), the self-report symptom inventory was observed before treatment, 1 month and 3 months after treatment separately so as to assess the corresponding short-term, mid-term and long-term efficacies of the program of acupuncture and moxibustion for soothing the liver and regulating the mind. In each time-point after treatment, for the scores of somatization, obsessive-compulsive symptom, interpersonal sensitivity, depression, anxiety, hostility, paranoid ideation, psychoticism and the other 8 dimensionalities, in comparison between the soothing-liver and regulating-mind group and the non-acupoint-shallow-puncturing group, the differences were significant statistically (all P < 0.05). For the scores of depression, anxiety and hostility, in comparison between the soothing-liver and regulating-mind group and the acupoint-shallow-puncturing group, the differences were significant statistically (all P < 0.05). Acupuncture and moxibustion can improve the scores of SCL-90 scale for the patients with depression. The outcome indicators of the patient subjective reports can accurately assess the clinical efficacy.

This article describes the experiences of professor CHEN Quan-xin, an old famous TCM doctor, in the treatment of insomnia. He believes that insomnia stems from incoordination between nutrient qi and defensive qi and deficient cultivation of cardiac spirit, and treatment of insomnia need to regulate spirit and quiet heart coherently. Painless acupuncture method of Chen's flying needling is adopted including to select Shenmen (HT 7), Sanyinjiao (SP 6) and Anmian (Extra) as the main points and take special needling technique and grading reinforcing and reducing manipulations. During treatment, he pays attention to understanding patients' psychological and mental status through "watching one's expressions and weighing his words carefully".

To approach the central nervous mechanism of abdominal acupuncture by using resting-state functional magnetic resonance imaging (fMRI). Twelve old healthy volunteers were treated by standardized abdominal acupuncture with invigorating the kidney and nourishing marrow method and Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6), Guanyuan (CV 4), Qixue (KI 13), Shangqu (KI 17) and Huaroumen (ST 24) were selected. They were examined by using resting-state fMRI before and after treatment of abdominal acupuncture and the brain functional connectivities were analyzed based on bilateral hippocampus chosen as seed points. (1) Before acupuncture, functional connectivities were found in the bilateral middle frontal gyrus, bilateral superior temporal gyrus, bilateral middle temporal gyrus, bilateral thalamus, bilateral subiculum hippocampi, bilateral insula, the cupula and declivis of right cerebellum, left superior frontal gyrus, left head of caudate nucleus, left posterior cingulate gyrus and left inferior parietal lobule (all P < 0.05). (2) After acupuncture, functional connectivities were found in the bilateral superior frontal gyrus, bilateral superior temporal gyrus, bilateral middle temporal gyrus, bilateral thalamus, bilateral insula, bilateral subiculum hippocampi, bilateral inferior parietal lobule, bilateral postcentral gyrus, bilateral cingulate gyrus, right head of caudate nucleus, right middle occipital gyrus and right posterior cingulate gyrus (all P < 0.05). (3) After acupuncture, there were intensity functional connectivities greater than before acupuncture in the bilateral superior frontal gyrus, bilateral middle frontal gyrus, bilateral superior temporal gyrus, bilateral superior parietal lobule, right inferior frontal gyrus, right anterior cingulate gyrus, right fusiform gyrus, right precuneus and right postcentral gyrus, while the intensity of functional connectivities of left middle temporal gyrus, right lingual gyrus, left cuneus/precuneus and left inferior parietal lobule were attenuated. Abdominal acupuncture with invigorating the kidney and nourishing marrow method can improve the allomeric function of the brain cognition network of central nervous system.
