Objective To explore the effect of Shenling Baizhu Powder and moxibustion on serum brain-gut peptide in patients with diarrhea predominant irritable bowel syndrome (D-IBS). Methods Sixty D-IBS cases were randomly divided into two groups, 30 cases in the treatment group were given Shenling Baizhu Powder and moxibustion therapy, and 30 patients in the control group were given loperamide hydrochloride capsule. Treatment for the two groups lasted for 4 weeks. Clinical symptoms and serum brain gut peptide (5-HT, VIP and SP) levels of two groups were observed before and after treatment, clinical efficacy were evaluated. Results Markedly effective rate of the treatment group was 66.7% (20/30), better than 33.3% (10/30) in the control group (P<0.05). After treatment, clinical symptom scores of the treatment group decreased significantly (P<0.01), while only diarrhea and abdominal pain improved in the control group (P<0.01), with statistical significance (P<0.01). After treatment, serum 5-HT, VIP, and SP of the treatment group were decreased (P<0.01), while these indexes of the control group did not change significantly (P>0.05), with statistical significance (P<0.01). Conclusion Clinical efficacy of Shenling Baizhu Powder and moxibustion in treating D-IBS is better than that of loperamide hydrochloride capsule, and can significantly improve clinical symptoms and regulate serum brain-gut peptides levels.

Objective To investigate the diagnosis and the relationship between its clinicopathological characteristics,treatment and the prognosis of primary colorectal lymphoma.Methods The clinical data of 20 primary colorectal lymphoma patients who received operative treatment in the past 34 years in our hospital were retrospectively summarized,and the influence of treatment and each clinicopathological factor on prognosis was assessed.Results Tumor size,lymph node metastasis,invasion of neighboring organs and distant metastasis,and type of operative treatment were significantly related to the survival(P0.05).Conclusions Diagnosis of primary colorectal lymphoma before operation is difficult,and misdiagnosis is common.Operative treatment is the main therapeutic means for colorectal lymphoma.Radical operation combined with chemotherapy can gain a good prognosis.

Objective:To explore the safety and feasibility of da Vinci robot surgical systems in natural orifice specimen extraction surgery (NOSES) for rectal neoplasms.Methods:A descriptive cohort study was used. Inclusion criteria: (1) age ≥18 years old; (2) diagnosis of rectal cancer by biopsy via colonoscopy or benign neoplasm locating in rectum that could not be resected locally through the anus; (3) R0 resection can be achieved by preoperative evaluation; (4) the CDmax (maximum circumferential diameter) was ≤5 cm or specimens could still be extracted from the anus despite a CDmax exceeding 5 cm but was along the longitudinal axis of the rectum. Exclusion criteria: (1) emergency operation due to gastrointestinal obstruction, perforation, or bleeding; (2) distal metastasis, induding lung, bone, or liver, that could not be resected simultaneously; (3) history of abdominal surgery or any other contraindications for robotic surgery. Clinicopathological data of 162 patients with rectal neoplasms who underwent robotic NOSES at the General Surgery Department of the Second Xiangya Hospital of Central South University from March 2016 to July 2019 were retrospectively collected. Of 162 patients, 94 were male and 68 were female; the average age was (57±13) years; the average BMI was (23.5±3.2) kg/m 2; the average distance from tumor to the anal verge was (8.2±2.9) cm. Five trocars were used to perform total mesorectal excision (TME), and the descending colon artery was preserved. Sterile endoscope sleeve for the specimen extraction was inserted into the pelvic cavity through the anus, and the resected specimen was pulled out through the sleeve. Outcomes of safety (operation time, intraoperative blood loss and postoperative morbidity of complication) and oncological outcomes (number of lymph nodes harvested, rate of lymph node metastasis and rate of positive resection margin) were collected. Results:All the 162 cases completed robotic NOSES successfully with no conversion to laparotomy. The average operation time was (188.7±79.8) minutes; the average blood loss was (47.1±33.2) ml; the average and the maximum CDmax of specimens were (3.4±1.5) cm and 12 cm respectively. A total of 154 patients underwent robotic TME. One underwent robotic TME plus resection of liver metastasis; one underwent robotic TME plus partial transverse colectomy; two patients underwent robotic TME plus ovariectomy; another two underwent robotic TME plus hysterectomy; one patient underwent robotic TME plus left partial nephrectomy due to renal angioleiomyoma; another one underwent robotic TME plus ureteral repair due to intraoperative injury of the left ureter. All the specimens were extracted through the anus. Protective ileostomy was performed in 6.8% (11/162) of the patients. The average number of lymph node harvested was 14.9±5.1. According to pathological reports, 156 neoplasms were adenocarcinoma. Tis stage was 1.3% (2/156), T1 stage was 9.0% (14/156), T2 stage was 26.3% (41/156), T3 stage was 35.9% (56/156), and T4 stage was 27.6% (43/156). Lymph node metastasis accounted for 34.6% (54/156), and simultaneous liver metastasis was observed in one case. Circumferential resection margins (CRMs) and upper and lower resection margins were negative in all the patients. The average postoperative feeding time and postoperative hospital stay were (4.2±4.1) days and (11.4±7.7) days, respectively. Postoperative morbidity of complication was 12.3% (20/162). The incidence of anastomotic leakage was 4.9% (8/162), of which only 4 cases (2.5%) received ileostomy. Within postoperative 90-day, no anal dysfunction or death were found.Conclusion:Robotic NOSES for rectal neoplasms is safe and feasible.

Lingguizhugan Decoction (LGZG) has been investigated in basic studies, with satisfactory effects on insulin resistance in non-alcoholic fatty liver disease (NAFLD). This translational approach aimed to explore the effect and underlying mechanism of LGZG in clinical setting. A randomized, double-blinded, placebo-controlled trial was performed. A total of 243 eligible participants with NAFLD were equally allocated to receive LGZG (two groups: standard dose and low dose) or placebo for 12 weeks on the basis of lifestyle modifications. The primary efficacy variable was homeostasis model assessment of insulin resistance (HOMA-IR). Analyses were performed in two populations in accordance with body mass index (BMI; overweight/obese, BMI ⩾ 24 kg/m²; lean, BMI < 24 kg/m²). For overweight/obese participants, low-dose LGZG significantly decreased their HOMA-IR level compared with placebo (-0.19 (1.47) versus 0.08 (1.99), P = 0.038). For lean subjects, neither dose of LGZG showed a superior effect compared with placebo. Methylated DNA immunoprecipitation sequencing and real-time qPCR found that the DNA N6-methyladenine modification levels of protein phosphatase 1 regulatory subunit 3A (PPP1R3A) and autophagy related 3 (ATG3) significantly increased after LGZG intervention in overweight/obese population. Low-dose LGZG effectively improved insulin resistance in overweight/obese subjects with NAFLD. The underlying mechanism may be related to the regulation of DNA N6-methyladenine modification of PPP1R3A and ATG3. Lean subjects may not be a targeted population for LGZG.
