RESUMO

OBJECTIVE: To investigate the immediate effects of electro-acupuncture (EA) on endometrial blood flow among recurrent implantation failure (RIF) patients. METHODS: Eighty RIF patients, enrolled from March 2022 to December 2022, were randomly allocated into either the EA group (40 cases) or the waiting-list (WL) group (40 cases) by using a random number table. The EA group underwent acupuncture at points of Shenting (GV 24), Baihui (GV 4), Benshen (GB 13), bilateral Zigong (EX-CA 1), Huangshu (KI 16), Sanyinjiao (SP 6) and Xuehai (SP10), and electric acupuncture apparatus was connected to EX-CA 1, KI 16, SP 6, and SP 10 with disperse-dense waves at 4/20 Hz frequencies for 30 min after transvaginal ultrasound, while the WL group received no intervention. The primary outcome measured was the endometrial volume blood flow. The secondary outcomes included the bilateral uterine artery index, endometrial volume, endometrial blood flow type, vascular distribution index (VIMV) for endometrial and ovary, clinical pregnancy rate, and embryo implantation rate. RESULTS: In the EA group, there was a notable decrease in the bilateral pulsatility index and a significant improvement in the endometrial blood flow type post-EA (P<0.05). Both the endometrial blood flow type and VIMV for the endometrium and right ovary were markedly higher in the EA group compared to the WL group post-treatment (P<0.05). Conversely, no significant disparities were observed in vascular index, flow index, vascular blood flow index, uterine arterial blood flow indices, endometrial volume, clinical pregnancy rate and embryo implantation rate between the two groups after treatment (P>0.05). Besides, no adverse events related to EA were observed. CONCLUSIONS: EA can promptly ameliorate VIMV for the endometrial and right ovary, and endometrial blood flow type. Future randomized controlled trials are warranted to investigate the long-term effects of EA on blood flow of RIF patients and its implications for pregnancy outcomes.

RESUMO

BACKGROUND: Transvaginal oocyte retrieval is frequently followed by adverse events related to anesthesia and the procedure. Some research showed that transcutaneous electrical acupoint stimulation (TEAS) can relieve intraoperative pain and postoperative nausea. OBJECTIVE: This study examined whether TEAS can alleviate pain and relieve adverse symptoms after oocyte retrieval. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: Altogether 128 patients were randomly divided into the TEAS group and the mock TEAS group. The two groups received a 30-minute-long TEAS or mock TEAS treatment that began 30 min after oocyte retrieval. MAIN OUTCOME MEASURES: The primary outcome was the visual analog scale (VAS) pain score. Secondary outcomes were pressure pain threshold, McGill score, pain rating index (PRI), present pain intensity (PPI), VAS stress score, VAS anxiety score, and postoperative adverse symptoms. RESULTS: The baseline characteristics of the two groups were comparable (P > 0.05). The VAS pain scores of the TEAS group were lower than those of the mock TEAS group at 60 and 90 min after oocyte retrieval (P < 0.05). The McGill score, PRI and PPI in the TEAS group were significantly lower than those in the control group at 60 min after oocyte retrieval (P < 0.05). However, the two groups had equivalent beneficial effects regarding the negative emotions, such as nervousness and anxiety (P > 0.05). The TEAS group was superior to the mock TEAS group for relieving postoperative adverse symptoms (P < 0.05). CONCLUSION: TEAS treatment can relieve postoperative pain and postoperative adverse symptoms for patients undergoing oocyte retrieval.

RESUMO

Objectives: The current study aims to assess the effectiveness of acupuncture in improving the live birth rate (LBR), ongoing pregnancy rate (OPR), clinical pregnancy rate (CPR), biochemical pregnancy rate (BPR), and pregnancy loss (early abortion rate, late abortion rate, ectopic pregnancy rate) in patients with recurrent implantation failure (RIF). Design: This retrospective study compares the outcomes of patients with RIF who underwent frozen embryo transfer (FET) with or without acupuncture. Setting: The medical records of patients diagnosed with RIF and visiting Chengdu Xi'nan Gynecological Hospital between January 2018 and June 2021 were reviewed. The Chengdu Xi'nan Gynecological Hospital Ethics Committee approved this retrospective study (No. 2021-029). Participants: A total of 923 patients with RIF who underwent FET were included in this study. The patients were divided into two groups: the Acupuncture (n = 303) and the Non-acupuncture groups (n = 620). Exposure: The Acupuncture group consisted of 303 RIF patients who received acupuncture therapy in addition to standard hormone replacement therapy (HRT)/delayed hormone replacement therapy (d-HRT) for FET. The Non-acupuncture group consisted of 620 RIF patients who received only standard HRT/d-HRT for FET. Primary and secondary outcome measures: The primary outcome was the LBR. The secondary outcome referred to OPR, CPR, BPR, and pregnancy loss. Results: The Acupuncture group had significantly higher BPR (P = 0.08) and CPR (P = 0.049) than the Non-acupuncture group. A potentially higher LBR (P = 0.16) and OPR (P = 0.248) were observed in the Acupuncture group than in the Non-acupuncture group. However, the survival analysis did not show that acupuncture significantly promoted live birth. Conclusions: Acupuncture is an appropriate adjunctive technique in the in vitro fertilization process as it improves biochemical and clinical pregnancies. Therefore, it is necessary to be cautious about the role of acupuncture throughout the whole pregnancy cycle.

RESUMO

A Gram-stain-positive, aerobic, non-motile and mycolic-acid-containing strain, designated Y48T, was isolated from soil contaminated by crude oil located in the northern margin of the Qaidam Basin. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Y48T belongs to the genus Nocardia and is closely related to N. cummidelens DSM 44490T (99.0 % similarity), N. soli DSM 44488T (99.0 %), N. lasii 3C-HV12T (98.9 %), N. salmonicida NBRC 13393T (98.6 %), N. ignorata NBRC 108230T (98.6 %) and N. coubleae NBRC 108252T (98.6 %). The average nucleotide identity and DNA-DNA hybridization values between strain Y48T and the reference strains were 75.9-84.5 and 27.5-29.0 %, respectively, values that were below the thresholds for species delineation. Chemotaxonomic analysis indicated that the major fatty acids of strain Y48T were C16 : 0, summed feature 3 (C16 : 1ω6c/C16 : 1ω7c), C18 : 1ω9c and C18 : 0 10-methyl (TBSA). The respiratory quinone was MK-8(H4, ω-cycl). The polar lipid profile was composed of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, two glycolipids and three unidentified lipids. The cell-wall hydrolysates contained meso-diaminopimelic acid, with ribose, arabinose, glucose and galactose as whole-cell sugars. A combination of 16S rRNA gene sequence analysis, and phenotypic and chemotaxonomic characterizations demonstrated that strain Y48T represents a novel species of the genus Nocardia, for which the name Nocardia mangyaensis sp. nov. is proposed. The type strain is Y48T (=JCM 32795T=CGMCC 4.7494T).

RESUMO

Codonopsis pilosula (Franch.) Nannf. is a traditional Chinese herbal medicinal plant and a low-cost succedaneum for Panax ginseng and contains various bioactivity components. In this work, we first evaluated the effects of the inoculation of the plant growth-promoting rhizobacteria Bacillus amyloliquefaciens strain GB03 on growth and metabolite accumulation of C. pilosula. The results demonstrated that application of B. amyloliquefaciens GB03 significantly improved the growth of C. pilosula compared to DH5α, Luria broth medium, and water treatment, respectively. On the other hand, we observed that the content of lobetyolin, one of the most important secondary metabolites in C. pilosula, was obviously improved by inoculation of GB03 and almost reached twice that compared to the other three treatments. In addition, some amino acids of roots were elevated by GB03, although not significantly. In conclusion, B. amyloliquefaciens GB03 could induce positive effects on the growth and further stimulate accumulation of secondary metabolites in C. pilosula.
