RESUMEN
The liver metastasis is the primary factor attributing to the poor prognosis of colorectal cancer (CRC). Moxibustion has been used clinically against multiple malignancies. In this study, we explored the safety, efficacy, and the potential functional mechanisms of moxibustion in modulating the liver metastasis of CRC by using GFP-HCT116 cells-derived CRC liver metastasis model in Balb/c nude mice. The tumor bearing mice were randomly divided into model control and treatment groups. Moxibustion was applied to the BL18 and ST36 acupoints. CRC liver metastasis was measured by fluorescence imaging. Furthermore, feces from all mice were collected, and 16S rRNA analysis was used to assess their microbial diversity, which was analyzed for its correlation with liver metastasis. Our results indicated that the liver metastasis rate was decreased significantly by moxibustion treatment. Moxibustion treatment also caused statistically significant changes in the gut microbe population, suggesting that moxibustion reshaped the imbalanced gut microbiota in the CRC liver metastasis mice. Therefore, our findings provide new insights into the host-microbe crosstalk during CRC liver metastasis and suggest moxibustion could inhibit CRC liver metastasis by remolding the structure of destructed gut microbiota community. Moxibustion may serve as a complementary and alternative therapy for the treatment of patients with CRC liver metastasis.

OBJECTIVE: To compare the differences in functional connectivity(FC) between the hypothalamus and whole brain regions in patients with premature ovarian insufficiency (POI) and healthy volunteers based on resting-state functional magnetic resonance imaging (rs-fMRI) and investigate the mechanism of acupuncture on treatment of POI. METHODS: Twelve POI patients were recruited to the acupuncture group and 12 healthy volunteers to the control group. Patients in the acupuncture group received acupuncture at two groups of acupoints alternatively, including Baihui (GV20), Zhongwan (CV12), Shenting (GV24), Shenshu (BL23), Ciliaoï¼BL32ï¼ and so on, 30 min once time, 3 times per week for 12 weeks. The state of patients was evaluated by modified Kupperman Index (KI) and self-rating anxiety scale (SAS). Follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and anti-mullerian hormone (AMH) were tested by microparticle-based chemiluminescence. B ultrasonography was used to detect the antral follicle count (AFC). Meanwhile, POI patients and healthy volunteers underwent the rs-fMRI examination before and after acupuncture treatment and after enrollment, respectively. With hypothalamus as the region of interest, the differences in FC between the hypothalamus and other brain regions in POI patients and healthy volunteers and the changes of FC between the hypothalamus and whole brain regions in POI patients before and after acupuncture were observed. RESULTS: The SAS and KI scores of pre-treatment POI patients were higher than those in the control group ï¼P<0.01ï¼.In compa-rison with those pre-treatment, FSH, LH, and SAS and KI scores of POI patients decreased after treatment, while AFC increased (P<0.05). Compared with the control group, the FC of the left hypothalamus with left central sulcus, right middle occipital gyrus, and left paracentral lobule increased, but decreased with left globus pallidus of the lenticular nucleus in POI patients. Furthermore, the FC of the right hypothalamus with the left hippocampus, the left para-central lobule, and the right central sulcus increased, while the FC between the right hypothalamus and the right superior frontal gyrus decreased (P<0.05). For the acupuncture group, compared with the conditions before treatment, the FC of the right hypothalamus with the left inferior frontal gyrus, the left insula, and right inferior frontal gyrus was strengthened, but weakened with the left gyrus rectus (P<0.05). CONCLUSION: The abnormal FC between the hypothalamus and whole brain regions may be one of the central pathological factors of POI. Acupuncture can improve the ovarian function and clinical symptoms of patients with POI, which may be related to its effect in regulating the FC between the hypothalamus and multiple brain regions.

Electroacupuncture (EA) is considered to have a therapeutic effect in the relief of irritable bowel syndrome (IBS)-associated visceral hypersensitivity via the reduction of the level of 5-hydroxytryptamine (5-HT) and 5-HT3 receptors (5-HT3R). However, whether Epac1/Piezo2, as the upstream of 5-HT, is involved in this process remains unclear. We investigated whether EA at the ST36 and ST37 acupoints alleviated visceral and somatic hypersensitivity in a post-inflammatory IBS (PI-IBS) model mice via the Epac1-Piezo2 axis. In this study, we used 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced PI-IBS as a mouse model. Visceral sensitivity was assessed by the abdominal withdrawal reflex test. Somatic sensitivity was evaluated by the hind paw withdrawal threshold. Quantitative real-time PCR, immunofluorescence staining, ELISA, and Western blotting were performed to examine the expressions of Epac1, Piezo2, 5-HT, and 5-HT3R from the mouse distal colon/L5-S2 dorsal root ganglia (DRG). Our results showed that EA improved the increased visceral sensation and peripheral mechanical hyperalgesia in PI-IBS model mice, and the effects of EA were superior to the sham EA. EA significantly decreased the protein and mRNA levels of Epac1 and Piezo2, and reduced 5-HT and 5-HT3R expressions in the distal colon. Knockdown of colonic Piezo2 eliminated the effect of EA on somatic hypersensitivity. Combined knockdown of colonic Epac1 and Piezo2 synergized with EA in relieving visceral hypersensitivity and blocked the effect of EA on somatic hypersensitivity. Additionally, protein levels of Epac1 and Piezo2 were also found to be decreased in the L5-S2 DRGs after EA treatment. Taken together, our study suggested that EA at ST36 and ST37 can alleviate visceral and somatic hypersensitivity in PI-IBS model mice, which is closely related to the regulation of the Epac1-Piezo2 axis.

OBJECTIVE: To compare the curative effect on diarrhea-predominant irritable bowel syndrome (IBS-D) between acupuncture for regulating shen and strengthening spleen and pinaverium bromide, and explore the relevant mechanism of curative effect of acupuncture in view of polymorphism of 5-hydroxytryptamine transporter gene-linked polymorphic region (5-HTTLPR). METHODS: A total of 231 patients with IBS-D were randomized into an acupuncture group (154 cases) and a western medication group (77 cases) at the ratio of 2 to 1. In the acupuncture group, acupuncture was applied to acupoint regimen for regulating shen and strengthening spleen, i.e. Baihui (GV 20), Yintang (GV 29), Tianshu (ST 25), Shangjuxu (ST 37) and Zusanli (ST 36), etc. The treatment was given once every 2 days, 3 times a week. In the western medication group, pinaverium bromide was prescribed for oral administration, 50 mg each time, 3 times daily. The duration of treatment was 6 weeks in each group. Separately, before treatment, after treatment and in 3-month follow-up, the IBS symptom severity scale (IBS-SSS) and IBS quality of life scale (IBS-QOL) scores were adopted in assessment. After treatment, the curative effect and safety were compared between the two groups. Before treatment, 5-HTTLPR genotypes were determined in the patients. RESULTS: After treatment and in follow-up, the total scores of IBS-SSS in the patients of the two groups were all reduced as compared with those before treatment (P<0.01) and the scores in the acupuncture group were lower than those in the western medication group (P<0.01). After treatment and in follow-up, the total scores of IBS-QOL in the two groups were all increased as compared with those before treatment (P<0.01) and the score in the acupuncture group was higher than the western medication group in follow-up (P<0.01). The total effective rate was 79.2% (122/154) in the acupuncture group, higher than 58.4% (45/77) in the western medication group (P<0.01). There was no severe adverse reaction found in the two groups. The difference in the total score of IBS-SSS before and after treatment in the patients with LS and SS genotypes was greater than that in the patients with LL in the acupuncture group (P<0.01). The difference in the total score of ISB-SSS before and after treatment in the patients with SS genotype was greater than that in the patients with LL in the western medication group (P<0.01). The difference in the total score of IBS-SSS before and after treatment in the patients with LS and SS genotypes in the acupuncture group was greater than that in the patients with the same genotypes in the western medication group (P<0.01). CONCLUSION: Acupuncture for regulating shen and strengthening spleen achieves the more curative effect on IBS-D as compared with pinaverium bromide. The acupuncture regimen effectively relieves the clinical symptoms and improves the quality of life in patients as well as presents a satisfactory long-term effect and safety. The clinical curative effect of acupuncture is correlated with 5-HTTLPR polymorphism, in which, the curative effect of acupuncture may be more effective in the patients with LS and SS genotypes.

Post inflammatory irritable bowel syndrome (PI-IBS), a subset of IBS, is characterized by symptoms of visceral pain, bloating, and changed bowel habits that occur post initial episode of intestinal infection. Gut microbial dysbiosis or inflammation plays a key role in the pathogenesis of abdominal hypersensitivity of PI-IBS. Electroacupuncture (EA) stimulation results in an alleviated PI-IBS-associated symptom. This study investigated the effect of EA on IL-18 and gut microbial dysbiosis in one visceral hypersensitive rat models with PI-IBS. A trinitrobenzene sulfonic acid (TNBS)-induced visceral hypersensitivity rat model was developed. EA stimulation was applied to the ST25 and ST36 acupoints. Animals were assessed using abdominal withdrawal reflex (AWR) scores to determine the development of colonic visceral hypersensitivity. The 16S rRNA was used to correlate microbial diversity. IL-18 expression in colon was quantified by quantitative real-time PCR and western blotting. We identified that model rats had an increased visceral hypersensitivity to colorectal distention at different distention pressures compared with the normal group. Sensitivity to colorectal distention decreased after EA stimulation. The composition of the fecal microbiota was different between groups. Specifically, in the model group Empedobacter, Psychrobacter, Enterococcus, Butyricimonas, Vampirovibrio, Kurthia, Intestinimonas, Neisseria, Falsiporphyromonas, Bilophila, Fusobacterium, Alistipes, Veillonella, Flavonifractor, Clostridium XlVa were more abundant affected genera, whereas Lactobacillus was enriched in normal rats. EA stimulation was correlated with significant decrease in the phyla of Fusobacteria. The mRNA and protein levels of IL-18 were higher in the model group. Meanwhile, EA stimulation attenuated this response. In a word, our findings suggest that PI-IBS is associated with significant increase in IL-18 levels as well as an alteration in microbiome diversity. These changes can be reversed with EA treatment. EA stimulation has a positive effect in alleviating symptoms of visceral hypersensitivity and protecting the gastrointestinal tract.

Professor SHENG Can-ruo is a well-known national veteran doctor with over 70 years of clinical experience. He has unique academic thoughts and clinical experience for common diseases and some difficult and complicated diseases. This paper mainly introduces professor SHENG 's syndrome-differentiation thought and experience of acupoint selection for hot flashes. It is emphasized that common hot flashes, such as hot flashes and night sweats, are different between yin and yang. While regulating yin and yang, more attention should be paid to ying-wei harmony, which is not only suitable for women's perimenopausal syndrome, but also for a series of clinical diseases caused by refractory drugs such as endocrine therapy after breast cancer surgery. At the same time of acupoint selection based on syndrome differentiation, a more rational prescriptions should be made according to the duration of the disease and the experience acupoints to improve the clinical efficacy.

OBJECTIVE: To observe the effect of electroacupuncture (EA) at "Tianshu" (ST 25) on visceral pain and colonic mast cell (MCs) number and tryptase and SP expression in post-infectious irritable bowel syndrome (PI-IBS) rats, so as to reveal its mechanisms underlying improvement of PI-IBS. METHODS: Forty-five female Wistar rats were randomly divided into control, model and EA groups (15 rats/ group, 3 rats/group used for H. E. staining, and 12 rats/group for immunohistochemistry). The PI-IBS model was established by intra-anal injection of mixed liquor of 50% ethyl alcohol and trinitro-benzene-sulfonic acid (TNBS). EA (2 Hz/15 Hz, 0.5-1.0 mA) was applied to bilateral "Tianshu" (ST 25) for 30 min, once every day for 14 days. The visceral pain was measured by abdominal withdrawal reflex (AWR), for which the rectal implanted air balloon was dilated by infusion of normal saline. The histopathological changes of the colon tissue were observed after H. E. staining, and the colonic MCs were displayed by Toluidine blue staining. The expression of tryptase and SP proteins in the colon specimens were detected by immunohistochemistry. RESULTS: The AWR threshold was significantly lowered in the model group relevant to the control group (P<0.05) and considerably increased after EA intervention in comparison with the model group (P<0.05). The number of MCs and the expression levels of colonic tryptase and SP proteins in the colon tissues were significantly higher in the model group than in the control group (P<0.05), and obviously lower after EA intervention in the EA group than in the model group (P<0.05). CONCLUSION: EA of "Tianshu" (ST 25) can inhibit visceral pain in PI-IBS rats, which may be associated with its effects in activating MCs and down-regulating the expression of tryptase and SP proteins in the colonic tissues.

OBJECTIVE: To investigate the effects of salvianolic acid B (SA-B) on extracellular signal-regulated kinase (ERK) signal transduction pathway activated by transforming growth factor-ß1 (TGF-ß1) in rat hepatic stellate cells (HSCs). METHODS: HSCs were isolated from male Sprague-Dawley rats by in situ perfusion and Nycodenz density-gradient centrifugation method. TGF-ß1 and SA-B were directly added to the serum-free medium of HSCs. Total and phosphorylated ERK, MEK, Raf and α-smooth muscle actin (α-SMA) and type I collagen were assayed by Western blotting. RESULTS: Phosphorylation of MEK in HSCs with or without TGF-ß1 was inhibited by SA-B; however, phosphorylation of Raf in HSCs with or without TGF-ß1 was not inhibited by SA-B. Expression of α-SMA in HSCs with TGF-ß1 was inhibited by SA-B. Combination of SA-B and the inhibitors of ERK (PD98059) can effectively inhibit the expression of α-SMA. SA-B also inhibited synthesization of type I collagen in HSCs with or without TGF-ß1. CONCLUSION: The action point of SA-B inhibiting ERK signaling induced by TGF-ß1 in HSCs is the inhibition of the phosphorylation of MEK. SA-B reduces the increase of expression of α-SMA and protein synthesization of type I collagen induced by TGF-ß1 by means of inhibiting ERK signaling in activated HSCs of rats.
