The study investigated the effect of Buyang Huanwu Decoction(BYHWD) on endogenous biomarkers in the urine of rats with chronic inflammation induced by lipopolysaccharide(LPS) using ultra-high performance liquid chromatography-quadrupole-time-of-flight-mass spectrometry(UPLC-Q-TOF-MS), aiming to elucidate the molecular mechanism underlying the therapeutic effect of BYHWD on chronic inflammation from a metabolomics perspective. Male SD rats were randomly divided into a normal group, a model group, and low-, medium-, and high-dose BYHWD groups(7.5, 15, and 30 g·kg~(-1)). The model group and BYHWD groups received tail intravenous injection of LPS(200 μg·kg~(-1)) on the first day of each week, followed by oral administration of BYHWD once a day for four consecutive weeks. Urine samples were collected at the end of the administration period, and UPLC-Q-TOF-MS was used to analyze the metabolic profiles of the rat urine in each group. Multivariate statistical analysis methods such as principal component analysis(PCA), partial least squares-discriminant analysis(PLS-DA), and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to analyze the effect of BYHWD on endogenous metabolites. One-way ANOVA and variable importance for the projection(VIP) were used to screen for potential biomarkers related to chronic inflammation. The identified biomarkers were subjected to pathway and enrichment analysis using MetaboAnalyst 5.0. A total of 25 potential biomarkers were screened and identified in the rat urine in this experiment. Compared with the normal group, the model group showed significant increases in the levels of 14 substances(P<0.05) and significant decreases in the levels of 11 substances(P<0.05). BYHWD was able to effectively reverse the trend of most endogenous biomarkers. Compared with the model group, BYHWD significantly down-regulated 13 biomarkers(P<0.05) and up-regulated 10 biomarkers(P<0.05). The metabolic products were mainly related to the biosynthesis of pantothenic acid and coenzyme A, tryptophan metabolism, retinol metabolism, and propionate metabolism. BYHWD has therapeutic effect on chronic inflammation induced by LPS, which may be related to its ability to improve the levels of endogenous metabolites, enhance the body's anti-inflammatory and antioxidant capabilities, and restore normal metabolic activity.

Acupoint-symptom relationship in CHENG Dan-an's Note About Treatise on Cold-Attack was analyzed based on complex network, acupoint names and indications were extracted from the book, which provided ideas and methods for promoting the modernization of acupuncture and moxibustion by using complex network technology. A total of 112 acupoints in 201 acupuncture prescriptions were included, and the total frequency of acupoints was 880 times, forming 42 034 acupoint pairs. In terms of network indexes, compared with the complex network of comprehensive acupuncture books, such as Meridian and Acupoint Science, Zhenjiu Dacheng, Acupuncture A and B Meridians formed based on the same mathematical method, the complex network model for CHENG Dan-an's Note About Treatise on Cold-Attack shows more typical small world effect, which is characterized by higher network density (6.762) and shorter average path length (1.064). This phenomenon may be related to the tongue and pulse which added the link between acupoints. For the node indexes, the analysis of topological indexes such as Page Rank shows that acupoints represented by Dazhui (GV 14) has higher compatibility value in the treatment of exogenous diseases, which further demonstrates the clinical value of eigenvector centrality in guiding intelligent compatibility of points.

Under the background of artificial intelligence, the internationalization of acupuncture and moxibustion has braced an important opportunity. Intelligent medical equipment for acupuncture and moxibustion has entered from the laboratory into the clinic. However, the current research focuses on optimizing acupuncture treatment technology rather than innovating acupuncture theory. Internationally, the westernization of traditional acupuncture and the dilution of its characteristics are worrying. It is urgent to promote the China-led international standards of acupuncture and moxibustion and the patent protection of traditional acupuncture and moxibustion. Intelligent medical equipment will play the role of media, and promote the internationalization of traditional acupuncture and moxibustion with standardized and highly-integrated intelligent medical equipment for acupuncture and moxibustion, and integrate modern scientific and technological achievements. It is a feasible way for the internationalization of acupuncture and moxibustion.

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.

OBJECTIVE: To compare minimally invasive and traditional Chevron osteotomy in treating patients with mild to moderate hallux valgus. METHODS: Clinical data of 36 patients (36 feet) with mild to moderate hallux valgus from January 2019 to February 2021 were retrospectively analyzed, and divided into minimally invasive osteotomy(minimally invasive group) and traditional Chevron osteotomy(traditional group). There were 16 patients in minimally invasive group, including 1 male and 15 females, aged from 36 to 60 years old with an average of(49.0±9.5) years old;9 were mild and 7 were moderate according to Mann classification;treated with minimally invasive osteotomy with hollow screw fixation. There were 20 patients(20 feet) in traditional group, including 2 males and 18 females, aged from 38 to 65 years old with an average of(50.0±9.2) years old;11 were mild and 9 were moderate according to Mann classification;treated with traditional Chevron osteotomy. Hallux valgus angle (HVA), intermetatarsal angle (IMA) before and after operation at 12 months bewteen two groups were observed and compared, and American Orthopedic Foot and Ankle Society (AOFAS) forefoot score and visual analogue scale (VAS) before and after operation at 6 weeks and 12 months between two groups were compared. RESULTS: Thirty-six patiens were followed up from 14 to 30 months with an average of (21.00±5.77) months. All incisions were healed well at stageⅠwithout infection. There were no significant differences in HVA, IMA, AOFAS forefoot scores and VAS before and after operation at 12 months between two groups(P>0.05). However, AOFAS forefoot scores and VAS of minimally invasive group was significantly better than that of traditionl group at 6 weeks after operation (P<0.05). Postoperative HVA, IMA, AOFAS forefoot scores and VAS at 12 months bewteen two groups were improved better than that of preoperation(P<0.05). CONCLUSION Compared with traditional Chevron osteotomy, minimally invasive osteotomy has less trauma and quicker recovery. Both of them has similar clinical effects, and could receive satisfactory clinical effects, while treatment of minimally invasive osteotomy should pain attention to learning curve.

OBJECTIVE: To investigate the effect of chidamide on the killing activity of NK (Natural killer cell, NK) cells targeting K562 cells and its related mechanism. METHODS: K562 cells were pretreated with chidamide at different concentrations and cocultured with NK cells at different effect-target ratios. The killing effect of chidamide on K562 cells by NK cells, the expression of natural killer group 2 member D (NKG2D) ligands and apoptosis rate of K562 cells were detected by flow cytometry. RESULTS: The killing sensitivity of NK cells to K562 cells could be enhanced by chidamide. The expression of ULBP2 on K562 cell surface could be up-regulate, however, the expression of ULBP1 and MICA/MICB showed no statistically difference as compared with control group. Chidamide showed no obvious cytotoxicity to K562 cells. CONCLUSION Chidamide can significantly improve killing efficiency of NK cells on K562 cells, which may be related to the up-regulation of ULBP2 expression.

OBJECTIVE: To observe the repairing effects of estrogen and wheat-grain moxibustion on thin-type endometrium in rats and to explore its possible mechanism. METHODS: Forty healthy SPF-grade adult female SD rats were randomly divided into a normal group, a model group, an estrogen group and a moxibustion group according to random number table method, 10 rats in each group. The model of thin-type endometrium was established during estrous period in all the groups except for the normal group. No intervention was given in the normal group. The intragastric administration of 2 mL of 0.9% sodium chloride solution was applied the next day after modeling in the model group. The intragastric administration of 2 mL of estradiol was given the next day after modeling in the estrogen group. The wheat-grain moxibustion was given at "Guanyuan" (CV 4) and "Shenshu" (BL 23) the next day after modeling in the moxibustion group, 7 moxa cones for each acupoint. The treatment in 3 groups was given once a day. After three estrous cycles, the samples were collected during estrous period; the thickness and morphology of endometrium were observed by HE staining; the expressions of vimentin, keratin and vascular endothelial growth factor (VEGF) in endometrium tissue were detected by immunohistochemistry; the expressions of HOXA10 and LIF in endometrium tissue were detected by Western blot. RESULTS: The endometrial thickness in the model group was significantly thinner than that in the normal group (<0.01); compared with the model group, the endometrial thickness in the estrogen group and the moxibustion group were increased significantly (<0.05, <0.01); the endometrial thickness in the moxibustion group was insignificantly higher than that in the estrogen group (>0.05). The expressions of keratin, vimentin and VEGF in endometrium in the model group were significantly lower than those in the normal group (<0.01); compared with the model group, the expressions of keratin, vimentin and VEGF in endometrium in the estrogen group and the moxibustion group were significantly increased (<0.01). The expressions of keratin, vimentin and VEGF in the moxibustion group were insignificantly higher than those in the estrogen group (>0.05). The expressions of HOXA10 and LIF in endometrium in the model group were significantly lower than those in the normal group (<0.01); compared with the model group, the expressions of HOXA10 and LIF in endometrium in the estrogen group and moxibustion group were significantly increased (<0.05). CONCLUSION The wheat-grain moxibustion could up-regulate the expressions of keratin, vimentin and VEGF in endometrium to improve the endometrial thickness; in addition, it could increase the levels of factors related to endometrial receptivity including HOXA10, LIF, which improves endometrial receptivity and play a repair role.

OBJECTIVE: To observe the clinical effect of grain-moxibustion combined with medicine therapy for asthenospermia and oligospermia. METHODS: A tatal of 60 patients were randomized into an observation group (30 cases) and a control group (30 cases) according to 1︰1 ratio. In the control group, vitamin E capsules were taken orally one capsule each time, twice a day, and pills 6 g each time, three times a day for a total of 3 months. In the observation group, grain-moxibustion was applied at Guanyuan (CV 4)，Shenshu (BL 23) and Zusanli (ST 36) based on the control group, once a week for 3 months, with a total of 12 times. The sperm concentration and sperm progressive motility were measured by automatic sperm quality analysis system in the two groups, and the clinical effects were compared. Sperm DNA fragmentation index (DFI) in the observation group was measured by sperm nucleus chromosome structure assay (SCSA). RESULTS: ①The sperm concentrations and sperm progressive motilities after 1-month, 2-month and 3-month of treatment were increased compared with those before treatment in the two groups (<0.01), and they were increased with time. In the two groups, 2-month and 1-month of treatment, 3-month and 2-month of treatment were compared, the sperm concentrations and sperm progressive motilities were significantly increased (<0.01). The sperm concentrations after 1-month, 2-month and 3-month of treatment in the observation group were higher than those in the control group (<0.01), the sperm progressive motility after 3-month of treatment in the observation group was higher than that in the control group (<0.05). ②After 3-month of treatment，the DFI in the observation group was significantly reduced compared with that before treatment (<0.01). ③The total effective rate in the observation group after 3-month of treatment was 86.7% (26/30), which was superior to 63.3% (19/30) in the control group (<0.05). CONCLUSION Grain-moxibustion combined with medicine therapy can improve sperm concentration and sperm progressive motility, enhance the integrity of sperm DNA.
