[Effect of electroacupuncture on endometrial receptivity and IVF-ET pregnancy outcomes in patients with diminished ovarian reserve].

OBJECTIVE: To explore the effect of electroacupuncture on endometrial receptivity and the pregnancy outcomes of in vitro fertilization and embryo transfer (IVF-ET) in the patients with diminished ovarian reserve (DOR). METHODS: Sixty-eight patients of DOR undertaken IVF-ET were randomized into an observation group (34 cases, 2 cases dropped off) and a control group (34 cases, 1 case dropped off). In the control group, endometrial preparation was performed according to the routine protocol. In the observation group, on the base of the treatment as the control group, acupuncture was applied to Geshu (BL 17), Shenshu (BL 23), Mingmen (GV 4), Shiqizhui (EX-B 8), Ciliao (BL 32), Zhongliao (BL 33), Tianshu (ST 25), Qihai (CV 6) and Guanyuan (CV 4), etc. Electric stimulation was given at Ciliao (BL 32)-Zhongliao(BL 33), Tianshu (ST 25)-Zigong (EX-CA 1), with disperse-dense wave, 2 Hz/15 Hz in frequency and tolerable current in intensity. Electroacupuncture was given once every two days, 3 times weekly, lasing 3 menstrual cycles till 1 day before embryo transfer. The endometrial thickness and morphology were observed on the day of human chorionic gonadotropin (HCG) of egg retrieval cycle, the day of endometrial transformation in frozen-thawed embryo transfer (FET) cycle and the day of embryo transfer in both groups successively; as well as HCG positive rate, clinical pregnancy rate, embryo implantation rate and live birth rate. RESULTS: In the observation group, the proportion of type A endometrium on the embryo transfer day was higher than those on HCG day of the egg retrieval cycle and the endometrial transformation day of FET cycle (P<0.05), and also higher than that of the control group (P<0.01). In the observation group, HCG positive rate, clinical pregnancy rate, embryo implantation rate and live birth rate were 75.0% (24/32), 71.9% (23/32), 47.4% (27/57) and 56.3% (18/32) respectively, and all higher than 36.4% (12/33), 30.3% (10/33), 18.0% (11/61) and 15.2% (5/33) in the control group separately (P<0.01). CONCLUSION: Electroacupuncture improves the endometrial receptivity and IVF-ET pregnancy outcomes in the patients of diminished ovarian reserve.

[Xiao's "xingnaofusu" needling for regaining consciousness and the influence on width of the third ventricle in patients with persistent vegetative state].

OBJECTIVE: To observe the influence of Xiao's "xingnaofusu" needling (the technique for resuscitation) on regaining consciousness in the patients with persistent vegetative state (PVS). METHODS: A total of 50 patients of PVS were randomized into an observation group and a control group, 25 cases in each. The patients in the control group were treated by the routine western medicine, and those in the observation group treated by Xiao's "xingnaofusu" needling and routine western medicine. Baihui (GV20), Dingshen (Extra) to Shangen (Extra) (penetrating technique), Fengchi (GB20) to GB20 (penetrating technique), Neiguan (PC6) to Waiguan (TE5) (penetrating technique), Hegu (LI4) to Laogong (HT8) (penetrating technique) and Taichong (LR3) to Yongquan (KI1) (penetrating technique) were selected. The treatment was given once a day, 10 days as one treatment course, 3 courses in total. The coma recovery scale-revised (CRS-R) score, the modified Ashworth scale (MAS) score and the Glasgow coma scale (GCS) were separately compared before and after the treatment. Additionally, CT scanning was adopted to measure the width of the third ventricle before and after treatment so as to evaluate the clinical therapeutic effect. RESULTS: After the treatment, the CRS-R and GCS scores in the two groups increased remarkably, and MAS score reduced obviously as compared with that before the treatment(P<0.05); and the CRS-R and GCS scores were higher, and MAS score lower in the observation group than those in the control group(P<0.05). Compared with the control group, the width of the third ventricle reduced obviously in the observation group after the treatment(P<0.05). At the end of the treatment courses, the effective rate was 79.2%(19/24)in the observation group and was 47.8%(11/23) in the control group. The effective rate of the observation group was obviously higher than that of the control group (P<0.05). CONCLUSION: Xiao's "xingnaofusu" needling can remarkably improve the central nerve function, promote the recovery of brain function and the motor function of limbs, reduce the width of the third ventricle and improve the clinical therapeutic effect of regaining consciousness in the patients with PVS.

[Clinical effect of acupuncture combined with traditional Chinese medicine in treatment of oligozoospermia/asthenozoospermia: a meta-analysis].

OBJECTIVE: To evaluate the clinical effect of acupuncture combined with Chinese medicine in the treatment of oligozoospermia/asthenozoospermia. METHODS: Randomized controlled trials (RCTs) of acupuncture combined with traditional Chinese medicine (TCM) in the treatment of oligozoospermia/asthenozoospermia published up to February 15, 2019 were searched from databases of CNKI, CBM, Wanfang Data, VIP, PubMed, Embase, and The Cochrane Library. Two reviewers independently performed quality assessment and data extraction of the studies, and RevMan5.3 was used to perform the meta-analysis. RESULTS: A total of 13 articles with 12 RCTs were included, with a total of 1 183 patients. The meta-analysis showed that acupuncture combined with TCM achieved a significantly higher pregnancy rate than TCM alone in the treatment of oligozoospermia/asthenozoospermia(risk ratio [RR] ＝1.46, 95% confidence interval [CI]: 1.13－1.90，P＝0.004). The patients treated with acupuncture combined with TCM had a significantly higher effective rate than those treated with TCM alone (RR＝1.17, 95% CI：1.10－1.24, P<0.000 01). Compared with TCM alone, acupuncture combined with TCM achieved significantly better improvements in sperm survival rate (mean difference [MD]＝8.28, 95% CI: 6.48－10.08, P<0.000 01), sperm motility (MD＝17.01, 95%CI：11.06－22.96, P<0.000 01), sperm concentration (MD＝8.71, 95%CI：5.92－11.50, P<0.000 01), and number of grade A sperms (MD＝6.39, 95%CI：5.27－7.50, P<0.000 01). CONCLUSION: Acupuncture combined with TCM has a better clinical effect than TCM alone in the treatment of oligozoospermia/asthenozoospermia. Due to the low methodological quality of the studies included in this analysis, acupuncture combined with TCM in the treatment of oligozoospermia/asthenozoospermia should be used based on patients' conditions in clinical practice.

[Research progress on the mechanism of acupuncture and moxibustion in treatment of endometriosis].

The clinical and experimental researches of acupuncture and moxibustion on endometriosis during past 15 years were collected. The research progress underling the mechanism of acupuncture and moxibustion on endometriosis was summarized. By taken Chinese characters, i.e. "acupuncture-moxibustion" and "endometriosis" as well as the English words, i.e. "acupuncture therapy" and "endometriosis" as the searching words, the relevant articles were retrieved from Pubmed, Embase, Chinese China National Knowledge Infrastructure, Wanfang Database, Chongqing VIP and the China Biology Medicine Disc etc. The retrieval time was from January 2003 to October 2018. As a result, 41 articles of clinical studies and 18 articles of animal experiments were screened. Of them, 20 articles (including 18 articles of animal experiments and 2 articles of clinical trial) are related to the mechanism underling acupuncture and moxibustion on endometriosis. In term of the impacts on growth factors, enzymes and enzyme inhibitors, the mechanism of acupuncture and moxibustion was explored on the analgesia for endometriosis, the inhibition of ectopic tissue angiogenesis and invasive adhesion, as well as the regulation of immune function and endocrine. Moreover, the limitation and prospect on the current researches were proposed so as to provide the more reliable evidence for clinical treatment of endometriosis with acupuncture and moxibustion.

De-novo characterization of the soft-shelled turtle Pelodiscus sinensis transcriptome using Illumina RNA-Seq technology.

The soft-shelled turtle Pelodiscus sinensis is a high-profile turtle species because of its nutritional and medicinal value in Asian countries. However, little is known about the genes that are involved in formation of their nutritional quality traits, especially the molecular mechanisms responsible for unsaturated fatty acid and collagen biosynthesis. In the present study, the transcriptomes from six tissues from Pelodiscus sinensis were sequenced using an Illumina paired-end sequencing platform. We obtained more than 47 million sequencing reads and 73954 unigenes with an average size of 754 bp by de-novo assembly. In total, 55.19% of the unigenes (40814) had significant similarity with proteins in the National Center of Biotechnology Information (NCBI) non-redundant protein database and Swiss-Prot database (E-value <10(-5)). Of these annotated unigenes, 9156 and 11947 unigenes were assigned to 52 gene ontology categories (GO) and 25 clusters of orthologous groups (COG), respectively. In total, 26496 (35.83%) unigenes were assigned to 242 pathways using the Kyoto Encyclopedia of Genes and Genomes pathway database (KEGG). In addition, we found a number of highly expressed genes involved in the regulation of P. sinensis unsaturated fatty acid biosynthesis and collagen formation, including desaturases, growth factors, transcription factors, and extracellular matrix components. Our data represent the most comprehensive sequence resource available for the Chinese soft-shelled turtle and could provide a basis for new research on this turtle as well as the molecular genetics and functional genomics of other terrapins. To our knowledge, we report for the first time, the large-scale RNA sequencing (RNA-Seq) of terrapin animals and would enrich the knowledge of turtles for future research.
