Traditional Chinese medicine (TCM) plays an important role in preventing and treating diseases and improving human health. However, the complex bioactive components and regulation of signaling pathway and network restrict the elucidation of the mechanisms of action of TCM. A human being is regarded as a super "symbiont" composed of body cells and commensal microorganisms. Gut microbiota is the core commensal microorganism system of a human body, being considered as "the second genome" and the new "organ". Alterations in gut microbiota reflect the state of body health and progression of diseases. Recent investigations have revealed that the TCM rich in polysaccharides and polyphenols can modulate gut microbiota metabolites to rehabilitate gut homeostasis, thus ameliorating diseases via regulating gut-liver axis or gut-brain axis. This review summarizes the causal relationship and mechanisms of action of TCM in the treatment of diseases from the perspective of gut microbiota metabolites. Our findings are expected to provide new insights into the mechanisms of TCM in preventing and treating diseases and guidance for TCM-based drug discovery in the future.

Objective:To evaluate the efficacy and safety of Yang-Monti tube in the operation of bladder controllable outflow tract, and to compare the efficacy of single and double segments Yang-Monti tube in patients with urethral damage.Methods:The clinical data of 27 patients who underwent Yang-Monti tube surgery in West China Hospital of Sichuan University from January 2009 to February 2018 were retrospectively analyzed, including 14 cases of single segment ileum (single segment group) and 13 cases of double segment ileum (double segment group). The age of single-segment group and double-segment group was (56.5±4.3) years and (50.2±6.8) years, respectively ( P=0.220). There were 2/12 and 3/10 males and females, respectively ( P=0.564). The body mass index (BMI) was (19.6±1.3) kg/m2 and (24.2±2.1) kg/m2, respectively ( P<0.001). The disease duration was 6 (3-24) months and 8 (3-48) months, respectively ( P=0.650). The preoperative quality of life (QOL) score was (46.7±1.7) and (45.5±1.7), respectively ( P=0.061). The number of patients with urinary tract infection before operation was 11 and 13, respectively ( P=0.480). In the single-segment group, a 2 cm ileum with mesangial vessels was cut at a distance of about 15 cm from the ileocecal part, and the intestine was cut longitudinally along the direction of the intestinal canal at the opposite mesangial margin. The intestinal piece was wrapped horizontally around the F12 urinary tube and wound into a Yang-Monti tube by intermittent suture with a 3-0 single thread. The bladder wall was cut anterolateral to the top wall of the bladder, about 1 cm in length, and the Yang-Monti tube was anastomosed end-to-end with the mucosal muscularis of the bladder wall. A circular incision with a diameter of about 1 cm was made at the level of the anterior superior iliac spine at the rectus abdominis muscle, and a tunnel was formed by puncture into the abdomen with curved forceps. The Yang-Monti tube was led out of the abdominal wall along the tunnel, and the tube opening was fixed with subcutaneous suture. At the same time, the tube wall was fixed in the peritoneum with 4-0 silk thread. In the double-segment group, two segments of 2 cm ileum were cut, and the intestinal tube was cut longitudes along the direction of the opposite mesangial margin. The intestinal piece was first sutured end to end, and then the tube was coiled and reconstructed to form a Yang-Monti tube with a diameter of 0.6-0.8 cm and a length of about 12 cm. The proximal end of the Yang-Monti tube was directly anastomosed with the mucosal muscle layer of the bladder. The operation time, intraoperative blood loss, postoperative catheterization interval, postoperative single catheterization volume, postoperative complications (bleeding, intestinal obstruction, anastomotic leakage, anastomotic stenosis, stoma infection, urinary tract infection, urinary tract infection) and QOL score were compared between the two groups. Results:The operation was successfully completed in both groups. The operation time of single-segment group and double-segment group were (165.8±17.8) min and (157.54±12.25) min, respectively ( P=0.302), and the intraoperative blood loss was (60.0±20.0) ml and (50.00±25.00) ml, respectively ( P=0.650). The postoperative recovery time was 3 (2-4) d and 3 (2-9) d, respectively ( P=0.790), and the postoperative hospital stay was 12 (9-40) d and 12 (10-32) d, respectively (P=0.259). The postoperative single catheterization volume was (240.4±42.7) ml and (261.5±36.3) ml ( P=0.186), and the postoperative QOL was (22.4±2.7) and (21.5±2.6), respectively ( P=0.325), and there was no significant difference. There were 2 cases of urinary tract infection in the single-segment group, and 1 case of urinary tract infection, postoperative bleeding, and intestinal obstruction in the double-segment group. There was no significant difference between the two groups ( P=0.222). The time interval of catheterization in single-segment group and double-segment group was (2.5±1.0) h and (3.5±1.3) h, respectively, and the difference was statistically significant ( P=0.029). The quality of life score after operation was statistically significant compared with that before operation ( P<0.001), and the incidence of urinary tract infection after operation was also statistically significant compared with that before operation ( P=0.011). Conclusions:Both single segment and double segment ileum Yang-Monti tube surgery are feasible surgical methods for patients with urethral damage. There was no difference in the effects of the two types of surgery, and both may improve the quality of life of patients.The postoperative QOL score could be greatly improved and the incidence of complications was low.

OBJECTIVETo observe the efficacy difference among medication, medication plus rehabilitation training and medication plus rehabilitation training plus acupuncture on injury of nervus peroneus communis.

METHODSA total of 81 patients were randomly divided into a control group, an observation 1 group and an observation 2 group; three patients dropped out and 78 patients were included into statistical analysis, 26 patients in each group. The patients in the control group were treated with oral administration of mecobalamin, 500 μg per time, 3 times a day for 60 days. Based on the treatment of control group, the patients in the observation 1 group were treated with rehabilitation training by computer-aided movable and measurable ankle-foot orthosis (CMM-AFO). Based on the treatment of observation 1 group, the patients in the observation 2 group were treated with acupuncture at Jiexi (ST 41), Fenglong (ST 40), Yanglingquan (GB 34) and Zusanli (ST 36), etc, 30 min per treatment, once a day for 60 days. After 60-day treatment, the clinical efficacy was evaluated; the muscle strengths of foot dorsal stretch and digital flexion were evaluated; the motor nerve conduction velocity (MCV) and sensory nerve conduction velocity (SCV) were recorded.

RESULTSAfter treatment, 20 patients were cured in the observation 2 group, which was significantly higher than 8 patients in the control group and 15 patients in the observation 1 group (both <0.05). The muscle strengths, SCV and MCV in the observation 2 group were significantly higher than those in the control group and the observation 1 group (all <0.05).

CONCLUSIONAcupuncture combined with CMM-AFO have significant efficacy on injury of nervus peroneus communis, and improve muscle strengths, SCV and MCV, which are superior to medication alone and medication plus rehabilitation training.
