RESUMO
The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.
RESUMO
Functional constipation (FC) is a common functional bowel disorder disease that affects life quality of a large number of people. This study aimed to explore the impact of different intensities of electro-acupuncture (EA) treatment for FC patients. Totally, 111 patients with FC meeting the Rome III criteria were randomly assigned to different intensities of EA groups (low and high intensity of EA groups) and medicine-controlled (MC) group. In EA groups, patients were treated with EA at quchi (LI11) and shangjuxu (ST37) bilaterally for 4 weeks, 5 times/week in the first 2 weeks, and 3 times/week in the last 2 weeks. In MC group, 5 mg mosapride citrate was administered orally 3 times/day for 4 weeks. Spontaneous bowel movement frequency each day was recorded using a constipation diary. Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to assess the patients' psychological state. Cortisol (CORT), substance P (SP), and vasoactive intestinal polypeptide (VIP) were evaluated at baseline and at the end of 4 weeks after treatment. As compared with the baseline, there was statistically significant increase in stool frequency every week (P<0.01), but there was no statistically significant difference among the three groups. As compared with the baseline, after 4 weeks of EA therapy, the scores of SDS and serum levels of CORT were decreased significantly in low intensity of EA group (P<0.01), and the serum levels of SP and VIP were increased significantly (P<0.05); the scores of SAS and SDS and serum levels of CORT were decreased significantly in high intensity of EA group (P<0.05), and the serum levels of SP and VIP were increased significantly (P<0.05); the serum levels of CORT and VIP were increased significantly in MC group (P<0.05). As compared with MC group, after 4 weeks of treatment, the serum levels of SP were signifcicantly increased in low intensity of EA group (P<0.01). Low and high intensities of EA could increase the stool frequency, improve the FC patient's anxiety and depression, reduce the serum levels of CORT, and increase the serum levels of SP and VIP effectively. It is concluded that both low and high intensities of EA are effective for FC patients, but there is no significant difference between the low and high intensities of EA.

<p><b>BACKGROUND</b>Connexin 43 (Cx43) is one of the major components of human keratinocyte gap junctions. To study whether gap junctional intercellular communication participates in the transfer of acupoint signals and acupuncture analgesia, the expression of Cx43 was studied in Zusanli (ST36) acupoints compared with control non-acupoint regions in rats after acupuncture. In addition, Cx43 heterozygous gene knockout mice were used to further explore the relationship between Cx43 and acupuncture analgesia.</p><p><b>METHODS</b>The expression of Cx43 was detected by immunohistochemistry, immunoblotting, and RT-PCR for the Cx43 protein and mRNA. The influence of the Cx43 gene knockout on acupuncture analgesia was measured by a hot plate and observing the writhing response on Cx43 heterozygous gene knockout mice.</p><p><b>RESULTS</b>Immunohistochemistry showed abundant Cx43 expression in some cells in the skin and subcutaneous tissue of rat ST36 acupoints. The mRNA and protein levels of Cx43 in acupoints were significantly higher than those in the control points in the non-acupuncture group, and even more so after acupuncture. The hot plate and writhing response experiments showed that partial knockout of the Cx43 gene decreased acupuncture analgesia.</p><p><b>CONCLUSION</b>Cx43 expression and acupuncture analgesia showed a positive correlation.</p>

<p><b>OBJECTIVE</b>To observe the influence of silencing Connexin43 (Cx43) expression of partial acupoints on acupuncture effect, so as to probe into the mechanism of acupuncture treatment for primary dysmenorrhea.</p><p><b>METHODS</b>The primary dysmenorrheal rat model made by oxytocin and RNA interference (RNAi) technology was used to silence the expression of Cx43 in acupoints. Fifty SD female rats were divided into five groups, a normal group (N), a model group (M), an acupuncture group (A), an acupuncture plus interference group (A+I), an acupuncture plus interference control group (A+IC). RT-PCR method was used to observe the oxytocin receptor (OTR) and vasopressin receptor (VPR) mRNA expressions in the uterus in each group. Plasma prostaglandin E2 (PGE2) and PGF2alpha levels were detected by radioimmunoassay and ELISA, respectively.</p><p><b>RESULTS</b>(1) The times of writhing body (9.43 +/- 3.87 and 10.28 +/- 4.23) were significantly lower and the latency period of writhing body (12.43 +/- 3.46, 11.00 +/- 3.65) were longer in the group A and the group A+IC as compared with (15.43 +/- 5.13, 17.00 +/- 3.87) and (7.57 +/- 1.99, 8.43 +/- 2.57) in the group M and group A+I (P < 0.05), respectively. (2) The levels of Cx43 mR NA level and protein expression of acupoint in the group A+I were significantly lower than those of the group N (P < 0.05). (3) OTR and VPR mRNA in the uterus in the group A and the group A+IC were significantly lower than those in the group M and the group A+I (P < 0.05), with no significant difference between the group M and the group A+I (P > 0.05). (4) As compared with the group M, PGE2 level increased and PGF2alpha level decreased in the group A and the group A+IC (P < 0.05).</p><p><b>CONCLUSION</b>Silencing Cx43 expression of partial acupoint can inhibit effectively the effect of acupuncture through decreasing OTR and VPR in endometrium of the dysmenorrheal rat and adjusting the prostaglandins (PGs) synthesis system, which possibly is one of the mechanisms of acupuncture for treatment of primary dysmenorrhea.</p>
