RESUMO
OBJECTIVE@#To evaluate the effect of manual acupuncture on endometrial blood flow parameters by three-dimensional (3D) power Doppler ultrasound in women undergoing in vitro fertilization embryo transfer (IVF-ET).@*METHODS@#Seventy patients undergoing IVF-ET were equally randomized into traditional or sham acupuncture treatment group for totally 4 days (from the day of oocyte aspiration to the day of embryo transfer) of treatment by random envelope method at the Reproductive Medicine Center and Outpatient Department of Integrated Traditional Chinese and Western Medicine, Tongji Hospital, Tongji Medicine College, Huazhong University of Science and Technology from January 2013 to December 2015. Patients in the traditional acupuncture group accepted traditional acupuncture methods with manual acupuncture, and Zhongji (CV3), Qihai (CV 6), Sanyinjiao (SP6), Taichong (LR 3), Tianshu (ST 25), Guilai (ST 29) and Zusanli (ST 36) were chosen. Patients at the sham acupuncture group accepted shallow acupuncture methods at 4 non-meridian points at each shoulder and upper arm. Outcome measures included endometrial ultrasonic indices such as vascularization index (VI), flow index (FI) and vascularization flow index (VFI), endometrial thickness and volume, subendometrial VI (sVI), subendometrial FI (sFI), subendometrial VFI (sVFI), implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births.@*RESULTS@#Finally, 34 patients in the traditional acupuncture group and 35 in the sham acupuncture group completed this trial. VI, FI and VFI of the traditional acupuncture group were significantly higher than those in the sham acupuncture group (P<0.05). No significant differences were found in endometrial thickness, endometrial volume, sVI, sFI, sVFI, implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births (P>0.05).@*CONCLUSIONS@#Manual acupuncture performed after oocyte aspiration and before transplantation improved the endometrial blood flow parameters VI, RI and VFI in women who underwent IVF-ET, instead of sVI, sFI and sVFI. Therefore, acupuncture might be beneficial in women undergoing IVF-ET by increasing endometrial blood flow and endometrial receptivity. (Registration No. ChiCTR2100053354).

OBJECTIVE@#JieZe-1 (JZ-1), a Chinese herbal prescription, has an obvious effect on genital herpes, which is mainly caused by herpes simplex virus type 2 (HSV-2). Our study aimed to address whether HSV-2 induces pyroptosis of VK2/E6E7 cells and to investigate the anti-HSV-2 activity of JZ-1 and the effect of JZ-1 on caspase-1-dependent pyroptosis.@*METHODS@#HSV-2-infected VK2/E6E7 cells and culture supernate were harvested at different time points after the infection. Cells were co-treated with HSV-2 and penciclovir (0.078125 mg/mL) or caspase-1 inhibitor VX-765 (24 h pretreatment with 100 μmol/L) or JZ-1 (0.078125-50 mg/mL). Cell counting kit-8 assay and viral load analysis were used to evaluate the antiviral activity of JZ-1. Inflammasome activation and pyroptosis of VK2/E6E7 cells were analyzed using microscopy, Hoechst 33342/propidium iodide staining, lactate dehydrogenase release assay, gene and protein expression, co-immunoprecipitation, immunofluorescence, and enzyme-linked immunosorbent assay.@*RESULTS@#HSV-2 induced pyroptosis of VK2/E6E7 cells, with the most significant increase observed 24 h after the infection. JZ-1 effectively inhibited HSV-2 (the 50% inhibitory concentration = 1.709 mg/mL), with the 6.25 mg/mL dose showing the highest efficacy (95.76%). JZ-1 (6.25 mg/mL) suppressed pyroptosis of VK2/E6E7 cells. It downregulated the inflammasome activation and pyroptosis via inhibiting the expression of nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing protein 3 (P < 0.001) and interferon-γ-inducible protein 16 (P < 0.001), and their interactions with apoptosis-associated speck-like protein containing a caspase recruitment domain, and reducing cleaved caspase-1 p20 (P < 0.01), gasdermin D-N (P < 0.01), interleukin (IL)-1β (P < 0.001), and IL-18 levels (P < 0.001).@*CONCLUSION@#JZ-1 exerts an excellent anti-HSV-2 effect in VK2/E6E7 cells, and it inhibits caspase-1-dependent pyroptosis induced by HSV-2 infection. These data enrich our understanding of the pathologic basis of HSV-2 infection and provide experimental evidence for the anti-HSV-2 activity of JZ-1.

<p><b>BACKGROUND</b>It has not been solved what kind of needle sensation might influence outcomes of acupuncture treatment. Effects of personality factors on the therapeutic effect of acupuncture have not been investigated. This study aimed to find the effects of the traits of personality on the objective outcome when different acupuncture techniques were used in treating patients with Bell's palsy.</p><p><b>METHODS</b>We performed a secondary analysis of a prospective multicenter randomized controlled trial of acupuncture for Bell's palsy. Patients were randomly assigned to the de qi and control groups, respectively. The primary outcome was facial nerve function at month 6. The intensity of each needle sensation was rated by a visual analog scale. Psychosocial factors were assessed by the pretreatment mediator questionnaire; 16 Personality Factor Questionnaire (16PF) was used for assessing personality factors and digit cancellation test for assessing attention.</p><p><b>RESULTS</b>After 6 months, patients in the de qi group had better facial function (adjusted odds ratio [OR]: 4.16, 95% confidence interval [CI]: 2.23-7.78). Path analysis showed that intensity of needle sensation of fullness had direct effect on House-Brackmann (HB) score at month 6. In de qi group, the low HB score on day 1 (OR: 0.13, 95% CI: 0.03-0.45) and the low Social Boldness score (OR: 0.63, 95% CI: 0.41-0.97) in 16PF were associated with better facial function. In control group, low HB score on day 1 (OR: 0.25, 95% CI: 0.13-0.50), low Vigilance score (OR: 0.66, 95% CI: 0.50-0.88), and high Tension score (OR: 1.41, 95% CI: 1.12-1.77) in 16PF were related to better facial function.</p><p><b>CONCLUSIONS</b>The needle sensation of fullness could predict better facial function and personality traits might influence outcomes of acupuncture treatment. Both of them should be considered seriously in acupuncture treatment and research.</p>

<p><b>OBJECTIVE</b>To investigate the effect of acupuncture on progesterone (P4) and prolactin (PRL) in rats of embryo implantation dysfunction (EID).</p><p><b>METHODS</b>On the first day of pregnancy, 72 female Wistar rats were randomly allocated into the normal group, the EID model group, the acupuncture group and the P4 group (18 in each group). The normal group was injected sesame oil, while the other three groups were given mifepristone to establish the EID model. The acupuncture group and the P4 group were given treatment of acupuncture and P4 injection, respectively. The serum of P4 and PRL were detected by radioimmunoassay, and the mRNA and protein expressions of P4 receptor (PR) and PRL receptor (PRLR) were detected using real-time polymerase chain reaction and immunohistochemical method, respectively.</p><p><b>RESULTS</b>Compared with the normal group, the serum levels of P4 and PRL as well as the mRNA and protein expression levels of PR and PRLR in the EID model group were significantly lowered (P<0.01 or P<0.05). The above indices in the acupuncture group and the P4 group were significantly elevated compared with the EID model group (P<0.01 or P<0.05).</p><p><b>CONCLUSION</b>Acupuncture can promote embryo implantation effectively, which might be related to the effects of acupuncture on upregulating the P4 and PRL levels in serum and the PR and PRLR expression levels in rats.</p>

To observe the effect of acupuncture on CXCL8 receptors (CXCR1 and CXCR2) in rat endometrium experiencing embryo implantation failure, 72 pregnant rats were randomly divided into four groups: normal group (N), embryo implantation failure group (M), acupuncture treatment group (A), and progestin treatment group (W). Then the rats in each group were equally randomized into a day-6 (D6) group, a day-8 (D8) group, and a day-10 (D10) group. The rats in group M, group A, and group W were treated with mifepristone-sesame oil solution on day 1, while the rats in group N were injected with the same amount of sesame oil. Meanwhile, "Housanli" and "Sanyinjiao" were selected for acupuncture. From day 1 to the time of death, the rats in group A were fastened up and then acupuncture was administered while the rats in group N and group M were only fixed, and the rats in group W were given progestin. The number of implanted embryos was calculated. The expression of CXCR1 and CXCR2 in rat endometrium was detected by immunohistochemistry, Western blotting and real-time PCR. Compared to group N, the average number of implanted embryos, the protein and mRNA expression of CXCR1 (D6, D8 and D10), and the protein and mRNA expression of CXCR2 (D8 and D10) in rat endometrium were significantly decreased in group M. Compared to group M, there was significant elevation in the average number of implanted embryos, the protein expression (D6, D8 and D10) and mRNA expression (D8) of CXCR1 in rat endometrium of group A, and the protein expression (D8 and D10) and mRNA expression (D8) of CXCR2 in rat endometrium of group W. These findings indicated that acupuncture can increase the number of implanted embryos in rats of embryo implantation failure, which may be relevant with up-regulation the expression of CXCR1 and CXCR2 at maternal-fetal interface of rats with embryo implantation failure.
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.

Interactions of vascular endothelial growth factor (VEGF) with receptors VEGFR1/Flt1 and VEGFR2/Flk1, and those of angiopoietins (Ang-1, Ang-2) with receptor Tie2 play important roles in placental angiogenesis. This study investigated vascular morphology and expression of these angiogenic factors in rat placenta on the day 15, 18, 21 of gestation (D15, D18 and D21). The rats were randomly assigned into 3 groups: normal group, model group [fetal growth restriction (FGR) model], and Bushen Yiqi Huoxue (BYHR) recipe treatment group (BYHR group, the pregnant rats with FGR were treated with BYHR recipe). Morphological analysis indicated that during initial villous formation, fetal nucleated erythrocytes (FNEs) appeared in maternal blood sinus (MBS). Subsequently, FNEs were surrounded by endothelial cells to form fetal capillary (FC) and then by trophoblast cells to form villi. As pregnancy proceeded, FC density increased progressively with increasing endothelial identification staining (EIS) in normal and BYHR groups. Whereas, villous formation was suppressed, normal increase in FC density was impaired and EIS was weakened in model group. Quantitative PCR analysis showed that VEGF and Flk1 mRNA increased over gestation in all groups, indicating that VEGF might play a pivotal role in FC growth during late gestation. VEGF mRNA was increased on D15, while decreased on D21 in model group as compared with normal group and BYHR group. Immunohistochemically, Ang-2 protein was highly expressed in FNEs, gradually disappeared as villi matured, and decreased over gestation in all groups, indicating that Ang-2 might play a pivotal role in villous formation, which was further supported by decreased Ang-2 mRNA and protein expression in model group on D15. Ang-1 mRNA, Tie2 mRNA and Ang-1/Ang-2 ratio increased from D15 to D18 in all groups as placenta matured. Ang-1 mRNA, Tie2 mRNA and Ang-1/Ang-2 ratio were decreased on D18 in model group as compared with normal and BYHR groups, indicating delayed maturity of FGR placenta. Alterations in angiogenic factors may result in altered placental vasculature and cause placental insufficiency. BYHR recipe could balance the angiogenic factors to promote the formation and maturation of FGR placental vasculature.

RESUMO
<p><b>OBJECTIVE</b>To study the impact of De-qi (, obtaining qi) and psychological factors on the efficacy of acupuncture treatment for primary dysmenorrhea, with an attempt to explore the relationship among De-qi, psychological factors, and clinical efficacy.</p><p><b>METHODS</b>The patients with primary dysmenorrhea were randomly assigned to a group of acupuncture with manual manipulation (manipulation group, n=67) and an acupuncture group without manipulation (non-manipulation group, n=64). Pain intensity and pain duration were used as measures for evaluating the therapeutic efficacy of the acupuncture treatment. De-qi, the sensations a patient experienced during the acupuncture treatment, was scored on a 4-point scale by the subjects. In addition, the psychological factors, including belief in acupuncture, the level of nervousness, anxiety, and depression, were quantitatively assessed. The personality of the subject was assessed using the Eysenck personality questionnaire (EPQ) and 16 personality factor questionnaire (16PF).</p><p><b>RESULTS</b>Complete data were obtained from 120 patients, 60 patients in each group. There were statistically significant differences in pain intensity (W=2410.0, P<0.01) and pain duration (W=3181.0, P<0.01) between the two groups. The number of De-qi acupoints (W=1150.5, P<0.01) and the average intensity of De-qi (W=1141.0, P<0.01) were significantly higher in the manipulation group as compared with their non-manipulation counterparts. The correlation coefficients between De-qi and therapeutic efficacy of acupuncture were greater than those between psychological factors and therapeutic efficacy.</p><p><b>CONCLUSIONS</b>Compared with the psychological factors, De-qi contributed more to the pain-relieving effect of acupuncture in subjects with primary dysmenorrhea. Moreover, manual manipulation is a prerequisite for eliciting and enhancing the De-qi sensations, and De-qi is critical for achieving therapeutic effects.</p>

Acupuncture has been used to treat infertility extensively, including ovulatory dysfunction, in vitro fertilization and embryo transfer (IVF-ET), and male infertility. This review summarizes the recent studies which investigated the role of acupuncture in infertility. In conclusion, most of the existing studies suggest a positive effect of acupuncture in infertility treatment. Firstly, acupuncture may improve ovulation by modulating the central and peripheral nervous systems, the neuroendocrine and endocrine systems, the ovarian blood flow, and metabolism. Secondly, acupuncture can improve the outcome of IVF-ET, and the mechanisms may be related to the increased uterine blood flow, inhibited uterine motility, and the anesis of depression, anxiety and stress. Its effect on modulating immune function also suggests helpfulness in improving the outcome of IVF-ET. Finally, the studies suggest that acupuncture plays a positive role in male infertility, the mechanism of which is not yet clear. Even though a positive effect of acupuncture in infertility has been found, well-designed multi-center, prospective randomized controlled studies are still needed to provide more reliable and valid scientific evidence. Furthermore, it is urgent and necessary to clarify the mechanism of acupuncture for infertility.

<p><b>OBJECTIVE</b>To explore the relationship between psychological factors and efficacy of acupuncture on primary dysmenorrhea.</p><p><b>METHODS</b>Sixty cases of primary dysmenorrhea were observed. Before acupuncture treatment, the self-designed confidence questionnaire was used to assess patients' confidence in acupuncture efficacy. Visual Analogue Scale (VAS) was adopted to assess patients' tension level during acupuncture. Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were applied to assess the situations of patients' anxiety and depression. Eysenck's personality questionnaire (EPQ) and Cattell sixteen personality factors questionnaire (16PF) were provided to assess the personal characters of patients. Pain intensity, pain duration and accompanied symptoms were recorded before and after acupuncture treatment so as to assess the efficacy. Canonical correlation analysis was used to analyze the relationship between the psychological factors and acupuncture efficacy on primary dysmenorrhea.</p><p><b>RESULTS</b>There were significant differences in grading of dysmenorrhea, pain intensity score and pain duration after treatment as compared statistically with those before treatment (all P<0.001). The standardized coefficients of dominance (r=0.6797) and anxiety (r=-0.5906) in personality factors and the reduction of pain duration (r=0.9042) among efficacy indices were the highest. The overall correlation coefficients were all lower between the indices of psychological factors and canonical variables of dysmenorrhea efficacy.</p><p><b>CONCLUSION</b>Acupuncture efficacy on primary dysmenorrhea has a certain correlation with dominance and anxiety of patients' personality factors. But, the psychological factors do not play a leading role in acupuncture treatment.</p>

<p><b>OBJECTIVE</b>To observe the influence of acupuncture on the luteal function of rats with dysfunctional embryo implantation, and investigate its mechanism.</p><p><b>METHODS</b>The early pregnant female rats were randomly divided into a normal control group, a model group, an acupoint group and a non-acupoint group. The model rats with dysfunctional embryo implantation were established with Mifepristone. For acupuncture treatment, bilateral "Housanli" (ST 36) and "Sanyinjiao" (SP 6) were selected in the acupoint group, while the points around the acupoint were used in the non-acupoint group. In this experiment, the levels of luteinizing hormone (LH), estrodiol (Es) and progesterone (P) in serum were tested with radioimmunity method, the expression of vascular endothelial growth factor (VEGF) in ovary was examined with immunohistochemical assay and Western-blot, and also, the mRNA expression of VEGF and luteinizing hormone receptor (LHR) in ovary were detected with RT-PCR.</p><p><b>RESULTS</b>The levels of LH and P in serum, as well as the expression of VEGF, VEGF mRNA and LHR mRNA in ovary in the acupoint group were significantly higher than those in the model group and the non-acupoint group (P < 0.05), but there was no obvious difference from that of the normal control group.</p><p><b>CONCLUSION</b>Acupuncturing at "Housanli" (ST 36) and "Sanyinjiao" (SP 6) can increase the levels of LH and P in the serum, and up-regulate the expression of VEGF, VEGF mRNA and LHR mRNA in ovary, which may enhance the luteal function of rats with dysfunctional embryo implantation and improve its embryo implantation.</p>

<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 effect and mechanism of acupuncture on infertility of rats with polycystic ovarian syndrome (PCOS).</p><p><b>METHODS</b>PCOS rat model was induced by subcutaneous injection of oil solution of dehydroepiandrosterone (DHEA) in immature (24-day-old) female rats for continuous 20 days. Rats for control were given with same dose of oil for instead. PCOS rats were randomly divided into the model group untreated and the acupuncture group treated by needling acupoints of Guanyuan (CV4), Zhongji (CV3), Sanyin-jiao (SP6) and Zigong (CX-CA1), 15 min once a day for 5 continuous days, starting from the 80th day after birth. All rats were sacrificed at terminal of the treatment, their uterus and bilateral ovaries were dissected for observation and blood levels of sex hormones were measured.</p><p><b>RESULTS</b>compared with the model group, the number of implanted blastocyte and blastocyte implantation rate were higher and the blood levels of testosterone (T) and estradiol (E2) were lower in the acupuncture group (P < 0.05); but the difference between groups in serum levels of follicular stimulating hormone, luteinizing hormone and progesterone were of statistical insignificance (P > 0.05). Moreover, the wet weight of ovary was lower and the equipotent diameter and area of glandular organ and cavity, area ratio of gland and the stroma, and mean thickness of endometria were higher in the acupuncture group than those in the control group (P < 0.05).</p><p><b>CONCLUSION</b>Acupuncture can conspicuously downregulate the expressions of serum levels of T and E2, improve the development of ovaries and uterus, promote ovulation, enhance endometrial receptivity, and advance blastocyte implantation.</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>

<p><b>OBJECTIVE</b>To probe the mechanism of acupuncture in treatment of dysmenorrhea.</p><p><b>METHODS</b>Adult mice with no pregnancy were randomly divided into a normal group, a model group, an acupuncture group and a medication group. The model group, the acupuncture group and the medication group were modeled by Diethylstilbestrol and Ocytocin. For the acupuncture group, at the 7th day of modeling, acupuncture was given at "Sanyinjiao" (SP 6), "Diji" (SP 8), once a day, for 5 days; and at the 7th day of modeling, Yimucao Gao 0.6 mg/g was given intragastrically to the medication group for 5 days. The stretching latent period and the number of stretching within 30 min were observed, and mRNA levels of ocytocin receptor (OctR) and vasopressin receptor (VasR) in the uterus tissue were detected with RT-PCR method.</p><p><b>RESULTS</b>Compared with the model group, the stretching latent period extended (P < 0.05) and the number of stretching within 30 min significantly decreased (P < 0.05); and there were significant differences in the mRNA levels of ocytocin receptor and vasopressin receptor in the uterus tissue in the model group as compared with those in other 3 groups (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>Acupuncture can improve the dysmenorrheal symptom to a certain extent, and the mechanism is possibly related to regulative effects of acupuncture on hormones-mediating receptors in mice.</p>
