Asarum forbesii is a perennial herb born in a shaded and humid environment, which is warm in nature. With the efficacy of warming lung, resolving fluid retention, and relieving coughs, it can be used to treat the syndrome of cold fluid accumulating in lung. To investigate the effects of different shading conditions on the composition and efficacy of A. forbesii, this study planted A. forbesii under 20% natural light(NL20), 40% natural light(NL40), 60% natural light(NL60), and 80% natural light(NL80) and utilized ultra performance liquid chromatography(UPLC) and micro broth 2-fold dilution method to detect the volatile chemical compounds and the minimum inhibitory concentration. At the same time, the study investigated the effects of A. forbesii grown under different shading conditions on the signs, pathological changes of lung tissues, serum cytokine levels, activities of mitochondrial respiratory chain complexes Ⅰ-Ⅴ in lung tissues, and relative expression of related genes of mice with syndrome of cold fluid accumulating in lung. The results indicated that with the increase of shading, the content of kakuol, methyl eugenol, and asarinin in A. forbesii and the antibacterial effect showed a tendency of increasing first and then decreasing, and the NL40 group was significantly better than the other groups. Under the conditions of NL20 and NL40, A. forbesii significantly alleviated the pathological damage to lung tissues, restored the homeostasis of the lung, and enhanced the energy metabolism level of mice with syndrome of cold fluid accumulating in lung. In addition, A. forbesii planted under the two conditions reduced the content of interleukin-8(IL-8), interleukin-13(IL-13), tumor necrosis factor-α(TNF-α), and mucin 5AC(MUC5AC), increased the levels of interleukin-10(IL-10) and aquaporin 1(AQP1), lowered the expression of MMP9, VEGF, TGF-β, and MAPK3. In conclusion, the therapeutic effect of A. forbesii on the syndrome of cold fluid accumulating in lung was positively correlated with the degree of shading, and the chemical composition and efficacy of warming lung and resolving fluid retention were optimal under the conditions of NL20-NL40. This study can provide reference for the pharmacological research and cultivation of A. forbesii.

Objective:To compare the feasibility and safety of a new portable endoscopic system and the conventional endoscopic system for the detection and emergency treatment of abdominal trauma in animal models.Methods:Three healthy Bama pigs, which were fasted and water deprivation for 8 h before surgery and then underwent induction anesthesia. A layer-by-layer incision was made into the abdominal cavity of Bama pigs. An artificial pneumoperitoneum was established using a laparoscopic pneumoperitoneum machine. A bullet model was inserted into the abdominal cavity to build the bullet wound model. After the bullet model was removed, a shrapnel model was inserted into the mid-abdomen to build the shrapnel wound model. The two types of endoscopic system were used to detect, remove bullet model or shrapnel model of the three Bama pigs respectively. The procedure order of the two systems was assigned according to the random number table method. The surgical success, operation time, endoscopy pipeline patency, endoscopic operation satisfaction, adverse events and equipment defects were recorded.Results:Three surgeries were performed using the new portable endoscopic system and three other surgeries using the conventional endoscopic system, all of which were successful. The time of the new portable endoscopic system to find and remove the bullet model, and the shrapnel model were 232.33±11.68 s, 300.33±57.70 s, 170.00±44.44 s and 52.67±2.52 s, respectively. The corresponding time of the conventional endoscopic system were 232.67±21.20 s ( t=-0.054, P=0.962), 256.67±67.00 s ( t=0.880, P=0.472), 176.00±52.42 s ( t=-0.111, P=0.922), 58.67±14.84 s ( t=-0.832, P=0.493), respectively. There was no significant difference between the two systems ( P>0.05). The endoscopy tubes of the two endoscopic systems were both smooth. The operator was satisfied with the endoscopic procedures of both endoscopic systems, and no adverse event or device defect occurred. Conclusion:The portable endoscopic system proves to be safe and feasible for the diagnosis and treatment of abdominal trauma in animal models.

Objective:To evaluate the quality of life (QoL) of Chinese chronic pancreatitis (CP) patients based on the Chinese version of the pancreatitis quality of life Instrument (PANQOLI) and explore its impact factors.Methods:404 patients with CP admitted to the Department of Gastroenterology of the First Affiliated Hospital of Naval Medical University between September 2021 and January 2022 were enrolled. The Chinese version of PANQOLI was used for questionnaire survey on QoL of CP patients. Univariate analysis and multiple linear regression analysis were used to explore the impact factors for QoL of CP patients.Results:The total score of QoL of 404 Chinese CP patients was 28-94(72.47±13.61), which declined by 29.64% compared to the highest total score (103) in the Chinese version of PANQOLI. Score of physical function, role function, emotional function, and self-worth domain was 25.63±4.84, 13.86±2.78, 16.98±6.21 and 16.00±4.65, respectively. Compared to the highest scores (30, 25, 24 and 24), the scores of aforementioned four domains declined by 14.57%, 44.56%, 29.25% and 33.33%, respectively. Univariate analysis showed that sex, age, employment status, smoking, alcohol consumption, and frequency of pancreatitis recurrence were significantly associated with QoL of CP patients. Multiple linear regression analysis indicated that older age (coefficient=-0.127), unemployment status (coefficient=-0.106), smoking (coefficient=-0.176), and high frequency of pancreatitis recurrence (coefficient=-0.123) were independent factors for QoL of CP patients (all P value <0.05). Conclusions:The Chinese version of PANQOLI could be effectively applied to Chinese CP patients. Older age, unemployment, smoking, and pancreatitis attacks were risk factors for QoL of CP patients, indicating that the formulation of personalized intervention measures may help to improve QoL of CP patients.

Objective:To explore the feasibility of 400 mL Sprite Zero ? in gastric preparation for magnetically controlled capsule endoscopy (MCE) . Methods:A randomized controlled trial at the Department of Gastroenterology of Changhai Hospital, Naval Medical University from December 16th, 2019 to January 15th, 2020 was conducted. The patients and healthy volunteers who intended to receive MCE were randomly divided into the Sprite Zero ? (S) group and the water (W) group at 1∶1. For subjects in the W group, 800 mL water was taken 10 minutes before swallowing the capsule. And for subjects in the S group, 400 mL Sprite Zero ? was taken. The primary endpoint was gastric filling score and the secondary endpoint included the fullness score, gastric transit time (GTT), small bowel transit time (SBTT), completion rate (CR) for small bowel examination and the diagnostic yield. Results:A total of 102 subjects were enrolled, 52 subjects in the S group and 50 subjects in the W group. The median score of gastric filling was 4 at 0-5 min, >5-10 min and >10-15 min after taking the capsule in both groups, with less median liquid consumption in the S group than the W group (500 mL VS 950 mL, P<0.001). The S group showed lower median fullness score (7.0 scores VS 7.5 scores, P=0.030) and higher proportion of patients with GTT less than 30 minutes [69.57% (16/52) VS 27.59% (8/29), P=0.030] compared with the W group. The CR of small bowel examination in the S group was 100.00%, higher than that of the W group (89.66%, P=0.245). Conclusion:Compared with 800 mL water, 400 mL Sprite Zero ? can fully fill the stomach with more comfort. It has the potential to accelerate gastric emptying and improve the CR of small bowel examination, which is feasible for the gastric preparation.

Objective:To evaluate the safety and effectiveness of capsule endoscopy for the diagnosis of intestinal diseases in children.Methods:Clinical data of 113 pediatric patients who received capsule endoscopy in Xi'an Children's Hospital from October 2018 to September 2020 were retrospectively analyzed. The completion rate, passage time of stomach and small intestine, lesion detection rate, adverse reactions and complications of capsule endoscopy were analyzed.Results:Among 113 pediatric patients, 78 (69.03%) were male and 35 (30.97%) were female. The age was (99.8±44.7) months (9-195 months), and 31 (27.43%) were under 7 years old. The minimum weight was 9 kg and the minimum height was 70 cm. Eighty-seven pediatric patients (76.99%) swallowed capsules orally (the oral group) with the minimum age of 4 years and 3 months. Capsules were implanted in 26 pediatric patients (23.01%) under gastroscopy (the gastroscopic group), with the maximum age of 9 years and 2 months. Unexplained abdominal pain (47.79%) and unexplained gastrointestinal bleeding (31.89%) were common in the pediatric patients. The completion rate of capsule endoscopy was 97.35% (110/113), and the detection rate of lesions in small intestine was 31.81% (35/110). The passage time of small intestine in the gastroscopic group was significantly longer than that of the oral group (461.04±129.27 min VS 288.23±107.84 min, t=5.646, P<0.01). There was no significant difference in the passage time of stomach or small intestine among different genders, different ages or different endoscopic examination results ( P>0.05). The positive results of capsule were not correlated with the method of ingestion ( P=0.401, OR=2.562, 95% CI:0.284-23.077), gender ( P=0.154, OR=2.352, 95% CI:0.726-7.616), age ( P=0.949, OR=1.007, 95% CI:0.816-1.242), examination reason ( P=0.246) or small intestine passage time ( P=0.219, OR=1.003, 95% CI:0.998-1.008). No complications such as capsule retention occurred in any pediatric patient. Conclusion:Capsule endoscopy in children is noninvasive, rapid and simple, which can improve the diagnostic rate of small intestinal diseases in children, and can be further promoted in pediatric patients.
