The incidence of acute gastrointestinal injury (AGI) in critically ill patients is high and significantly affects their clinical prognosis. Currently,there have been numerous studies in both western and Chinese medicine specialties on the diagnosis,prevention,and treatment of AGI,including investigations into high-risk factors prone to AGI,biomarkers for diagnosing AGI,scoring methods for evaluating gastrointestinal function in western medicine,syndrome differentiation in Chinese medicine,and treatment and prevention approaches of AGI in both western and Chinese medicine. To further standardize the strategies for the prevention and treatment of AGI in critically ill patients through the integration of Chinese and western medicine,this consensus convened experts in critical care medicine,evidence-based medicine,and methodology in the field of integrative Chinese and western medicine within the country to formulate the Chinese expert consensus on integrative Chinese and western medicine for the prevention and treatment of acute gastrointestinal injury in critically ill patients. This consensus is based on the PICO (patient,intervention,comparison,and outcome) principle and adopts the grading of recommendations,assessment,development and evaluation (GRADE) standard. It takes a problem-oriented approach from the perspective of the integration of Chinese and western medicine,this consensus summarizes the evidence-based medical evidence and puts forward recommendations on the definition,diagnosis,treatment and prevention of AGI to provide professional suggestions for the standardized implementation of the prevention and treatment of AGI in critically ill patients through integrative Chinese and western medicine.

Objective:To observe the protective effect of forsythiaside A on acute lung injury (ALI) in septic rats.Methods:Male Sprague-Dawley (SD) rats were randomly divided into normal control group, sham operation group, sepsis model group, and forsythiaside A intervention group, with 10 rats in each group. The rats in the normal control group did not receive any intervention; the rats in the sham operation group only underwent abdominal surgery; and those in the model group and forsythiaside A intervention group received cecal ligation and puncture (CLP) to establish the sepsis rat model. The rats in the forsythiaside A intervention group were given 75 mL/kg of forsythiaside A within 0.5 hour after operation, and repeated after 6 hours. The rats in the sham operation group and model group were given the same amount of normal saline at the same time points. The lung tissues were collected for pathological examination 12 hours after operation. The lung homogenate was prepared, and enzyme-linked immunosorbent assay (ELISA) was used to detect tumor necrosis factor-α (TNF-α), interleukins (IL-1β, IL-6). The activity of superoxide dismutase (SOD) was detected by xanthine oxidase method, and the content of malonaldehyde (MDA) was detected by colorimetry. The expression of nuclear factor-κB p65 (NF-κB p65) was detected by Western blotting.Results:There was no significant pathological change of lung tissue in both normal control group and sham operation group, and there was no significant difference in each parameter between the two groups. The rats in the model group had interstitial infiltration of inflammatory cells, alveolar structure destruction, alveolar septum thicken, extensive alveolar hemorrhage, telangiectasia; the levels of TNF-α, IL-1β, IL-6, MDA and NF-κB p65 protein expression in lung tissue were significantly higher than those in the normal control group and sham operation group [TNF-α (ng/L): 132.81±16.15 vs. 45.08±5.98, 46.10±6.72, IL-1β (ng/L): 137.32±15.22 vs. 51.03±7.89, 50.92±8.13; IL-6 (ng/L): 138.39±14.28 vs. 51.68±7.03, 52.48±7.36; MDA (kU/g): 1.79±0.13 vs. 0.96±0.05, 0.97±0.05; NF-κB p65 protein (NF-κB p65/GAPDH): 2.82±0.23 vs. 1.76±0.12, 1.82±0.13; all P < 0.05], the activity of SOD decreased significantly (kU/g: 45.90±5.46 vs. 92.11±10.13, 93.36±10.56, both P < 0.05). The changes in lung histopathology in the forsythiaside A intervention group were obviously improved as compared with the model group, which showed less inflammatory cell infiltration, less alveolar septum thickening, less bleeding and more intact structures; the levels of TNF-α, IL-1β, IL-6, MDA and the expression of NF-κB p65 protein in lung tissue were significantly lower than those in the model group [TNF-α (ng/L): 72.48±9.78 vs. 132.81±16.15, IL-1β (ng/L): 83.85±12.46 vs. 137.32±15.22, IL-6 (ng/L): 81.88±11.89 vs. 138.39±14.28, MDA (kU/L): 1.29±0.09 vs. 1.79±0.13, NF-κB p65 protein (NF-κB p65/GAPDH): 2.29±0.19 vs. 2.82±0.23, all P < 0.05], SOD activity increased significantly (kU/g: 66.03±7.98 vs. 45.90±5.46, P < 0.05). Conclusions:Forsythiaside A can effectively alleviate ALI in septic rats. The mechanism may be related to down-regulate the expression of NF-κB p65 and reduce the level of inflammatory factors and free radicals in lung tissue, thereby against acute lung injury in septic rats.

Objective: To observe the effect of moxibustion on the expression of N-methyl-D-aspartic acid (NMDA) receptor subtype 2B (NR2B) in the hippocampus of rheumatoid arthritis (RA) rats, and to explore the analgesic mechanisms of moxibustion in RA treatment. Methods: Sixty male Sprague-Dawley rats were randomly divided into a normal group, a model group, a moxibustion group, a moxibustion + NMDA receptor antagonist (AP-5) group, and a moxibustion + NMDA receptor agonist (NMDA) group, with 12 rats in each group. Except for the normal group, rats in the other four groups were treated with complete Freund's adjuvant in a windy, cold, and damp environment to replicate RA models. Rats in the moxibustion group received suspended moxibustion with moxa sticks at Shenshu (BL23) and Zusanli (ST36), and the two points were used alternately. After intraperitoneal injection of AP-5 or NMDA, rats in the moxibustion + AP-5 group and the moxibustion + NMDA group received the same moxibustion intervention as in the moxibustion group, once a day for 15 d. The thermal withdrawal latency (TWL) of rats in each group was detected before and after modeling and after the 15-day intervention. After the 15-day intervention, hematoxylin-eosin staining was performed to observe the pathological changes in knee joints. The real-time fluorescence quantitative polymerase chain reaction method was used to detect the mRNA expression of NR2B in the hippocampus; Western blotting assay was used to detect the protein and the phosphorylated protein expression of hippocampal NR2B. Results: The synovial tissue was proliferated, the synovial lining was significantly thickened, the pannus was formed, and the cartilage and bone tissues were significantly damaged in the model group. After intervention, the pathological morphology of the knee joints in the moxibustion group, the moxibustion + AP-5 group, and the moxibustion + NMDA group was significantly improved, and the improvement in the moxibustion + AP-5 group was more notable than that in the moxibustion + NMDA group. Compared with the normal group, the TWL was significantly decreased (P<0.01), and the mRNA, protein, and phosphorylated protein expression levels of hippocampal NR2B were significantly increased in the model group (P<0.01). Compared with the model group, the TWL of each intervention group was significantly increased (P<0.01 or P<0.05), and the mRNA, protein, and phosphorylated protein expression levels of hippocampal NR2B were significantly decreased (P<0.01). Compared with the moxibustion group, the TWL was significantly increased (P<0.01), and the mRNA, protein, and phosphorylated protein expression levels of hippocampal NR2B were significantly decreased in the moxibustion + AP-5 group (P<0.01); the TWL was significantly decreased (P<0.01), and the mRNA, protein, and phosphorylated protein expression levels of hippocampal NR2B were significantly increased in the moxibustion + NMDA group (P<0.01). Conclusion: Moxibustion reduces hyperalgesia in RA inflammatory rats. The analgesic effect may be related to the decrease in the expression and phosphorylation levels of NR2B in the hippocampus.

Objective:To evaluate the therapeutic effect of electroacupuncture on acute gastrointestinal injury (AGI) in patients with severe traumatic brain injury (sTBI).Methods:A prospective randomized controlled trial was conducted. 126 consecutively hospitalized patients with AGI after sTBI admitted to intensive care unit (ICU) of the First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from January 2018 to December 2019 were enrolled. The patients were divided into observation group and control group by random number table. All the patients of two groups were given conventional treatment of western medicine for consecutive 7 days, including the treatments of primary diseases, indwelling nasogastric tube to extract gastric contents every 6 hours to determine gastric residual volume (GRV). When vital signs were basically stable, enteral nutrition (EN) was implemented and EN feeding amount and speed were adjusted according to GRV. On the basis of conventional western medicine treatment, the observation group was treated with electroacupuncture at Zusanli, Tianshu, Shangjuxu, Xiajuxu and Zhongwan, once in the morning and once in the evening, 30 minutes each time. The gastrointestinal function parameters including intra-abdominal pressure (IAP), serum diamine oxidase (DAO) and gastrointestinal failure (GIF) scores were observed before treatment and at day 3 and day 7 of treatment. The incidence of ICU hospital-acquired pneumonia (HAP-ICU), duration of mechanical ventilation (MV), length of ICU stay, 28-day mortality and adverse reactions of electroacupuncture were also observed in the two groups. Kaplan-Meier method was used for 28-day survival analysis.Results:During the 7-day treatment and observation, 26 cases of 126 patients withdrew from the study, and 100 cases were actually enrolled, 50 cases in the observation group and 50 cases in the control group. IAP and DAO at day 3 of treatment in both groups were significantly lower than those before treatment [control group: IAP (cmH 2O, 1 cmH 2O = 0.098 kPa) was 13.75±2.76 vs. 18.11±3.97, DAO (U/L) was 129.88±24.81 vs. 158.01±22.64; observation group: IAP (cmH 2O) was 13.56±2.19 vs. 18.50±3.54, DAO (U/L) was 129.11±29.32 vs. 159.36±28.65; all P < 0.01]. The gastrointestinal function parameters of the two groups improved gradually with the extension of treatment time, and the IAP, DAO and GIF scores at day 7 of treatment in the observation group were significantly lower than those in the control group [IAP (cmH 2O): 11.28±3.61 vs. 12.68±3.23, DAO (U/L): 49.69±17.56 vs. 57.27±20.15, GIF score: 2.02±0.74 vs. 2.40±0.70, all P < 0.05). The duration of MV and the length of ICU stay in the observation group were significantly shorter than those in the control group [duration of MV (days): 15.72±4.60 vs. 18.08±4.54, length of ICU stay (days): 16.76±4.68 vs. 19.26±5.42, both P < 0.05], and the incidence of ICU-HAP and 28-day mortality were significantly lowered (12.0% vs. 30.0%, 22.0% vs. 32.0%, both P < 0.05). Survival analysis showed that the 28-day cumulative survival rate in the observation group was significantly higher than that in the control group (86.4% vs. 76.1%; Log-Rank test: χ 2 = 37.954, P < 0.001). The patients in the observation group had no significant adverse reaction of electroacupuncture treatment. Conclusion:Electroacupuncture at corresponding acupoints can effectively improve gastrointestinal function in patients with AGI after sTBI, which is beneficial to shortening the length of ICU stay, promoting the recovery of the patients, and reducing the 28-day mortality.

Objective To compare the characteristics,complications and outcomes of the modified lapa-roscopic Swenson(MLSw)and laparoscopic Soave(LS)procedures for children with short-segment Hirschsprung disease(HD). Methods Seventy-seven pediatric patients with HD who underwent surgery from March 2007 to December 2016 were enrolled in this retrospective study. Twenty-six patients were treated with LS and 51 cases un-derwent MLSw. The preoperative,operative and postoperative data was collected,with follow-up periods ranging from 12 to 48 months. The perioperative/operative characteristics,postoperative complications,and outcomes were compared between the two groups. Results On average,the patients in the LS group had a longer operating time than that in the MLSw group(P < 0.05). Blood loss was significantly less in the MLSw group than that in the LS group(P < 0.05). There was no significant difference in feeding time between the two groups(P > 0.05). The MLSw group was discharged after a shorter hospitalization time than that in the LS group(P < 0.05). The MLSw group had lower incidences of postoperative complications than those in the LS group in the early postoperative period,with no significant difference in the rate of complications during the late postoperative period was found between the two groups. Conclusions Both LS and MLSw are suitable for treatment of children with short-segment HD. However,the MLSw operation is much simpler,with less operating time,less intraoperative blood loss,shorter hospitalization time and better bowel control in the early postoperative period. We favor this approach because it allows complete removal of the entire original aganglionic bowel,without leaving behind a cuff.
