ObjectiveTo investigate the metabolic alterations of serum short chain fatty acids （SCFAs） in pediatric patients with atopic dermatitis （AD） and their correlation with different clinical phenotypes using targeted metabolomics. MethodsThis study enrolled 87 AD patients and 67 healthy controls （HC）. Serum levels of eight SCFAs were quantified by ultra-high-performance liquid chromatography-mass spectrometry. The associations between SCFAs and AD were assessed using various statistical methods. ResultsCompared with the HC group， levels of acetic acid （AA）， propionic acid （PA）， and caproic acid （CA） （P=0.002，P=0.002，P=0.043） decreased in the AD group. Logistic regression analysis identified AA （OR=0.449， 95% CI： 0.289–0.698） and PA （OR = 0.487， 95% CI： 0.324–0.732） as protective factors against AD. The combination of AA and PA yielded an area under the curve （AUC） greater than 0.7， indicating good diagnostic efficacy. Age-stratified analysis revealed that AA reduction was predominant in childhood， whereas PA reduction was predominant in adolescence. Pathway enrichment analysis showed significant enrichment of fatty acid biosynthesis （FDR=0.341， P=0.003） and vitamin K metabolism （FDR=1， P=0.039） pathways. Furthermore， subgroup analyses based on disease severity， personal/family history of atopy， and sex revealed no significant differences in SCFAs levels among the groups. ConclusionDifferential serum SCFAs and their enriched metabolic pathways may be implicated in the pathogenesis of AD.

Objective To explore the dilemma of self-management behavior maintenance in ischemic stroke patients,and to provide references for continuous self-management intervention design for ischemic stroke patients.Methods The descriptive qualitative research method was used to select samples by the purpose sampling method.From November to December 2023,18 patients hospitalised with stroke from the neurology ward of a tertiary general hospital in Luoyang City,Henan Province were selected for semi-structured interviews.Based on the Capability,Opportunity,Motivation-Behavior(COM-B)model,the data were analyzed by directed content analysis.Results A total of 3 themes and 12 sub-themes were identified,namely capability factors(poor level of health literacy,lack of self-control),opportunity factors(lack of medical resources impeding the maintenance of behaviors,social customs inducing the return of undesirable behaviors,difficult to satisfy the need for multiple emotional support,behavior being improved briefly after follow-up),and motivation factors(impulsive thinking,role conflict leading to forgetfulness,difficult to change previous bad habits,acceptance of the aging,weak self-management effect,symptoms inducing behavioral changes).Conclusion The maintenance of self-management behavior in ischemic stroke patients is affected by 3 aspects of obstacles,including capability,opportunity and motivation.On the premise of fully evaluating the specific characteristics of ischemic stroke patients,medical staff should meet the multidimensional needs of patients to promote the maintenance of self-management behaviors to improve their health outcomes.

Objective To investigate radiation doses to examinees undergoing computed tomography (CT) scanning of different body parts (the head, chest, and abdomen) in medical institutions of Shijiazhuang, China, and to provide a reference for optimizing radiation protection for examinees in medical institutions. Methods March 2021 to March 2022, eleven medical institutions of radiation monitoring in Shijiazhuang were surveyed for the basic information, scanning parameters, and dosimetric data of a total of 930 adults and children who received CT examinations. The dosimetric data of the subjects were analyzed and compared with the domestic and international diagnostic reference levels and the results of other cities in China. Results In the above hospitals, the CTDI_vol(P₅₀) of CT subjects in children's group were 17.42-50.45 mGy, 2.13-14.01 mGy and 3.58-28.20 mGy, respectively. DLP(P₅₀) ranges from 228.87 to 966.97 mGy·cm, 33.20 to 296.03 mGy·cm, and 74.90 to 926.53 mGy·cm, respectively. In the adult group, the CTDI_vol(P₅₀) in the head, chest and abdomen of CT subjects were 37.28-54.05 mGy, 6.43-14.99 mGy and 8.28-18.75 mGy, respectively. DLP(P₅₀) ranges from 372.81 to 630.56 mGy·cm, from 219.77 to 467.93 mGy·cm, and from 313.86 to 689.87 mGy·cm, respectively. The distribution of radiation doses in different-grade hospitals varied greatly. The abdomen dose of the children's hospital was higher than other hospitals. Especially the primary hospitals were significantly higher than the recommended diagnostic reference level (DRL). Conclusion In some secondary and primary hospitals, the setting of CT scanning parameters was simplified, not specific to the subjects’ age and body types. They should strictly comply with the principal of optimizing radiation protection to strengthen radiation dose optimization and supervision, reducing the radiation dose of examinees in future examinations .

A 29-year-old male patient was treated with levofloxacin and other treatments for ulcerative colitis. Due to poor curative effect, he was given infliximab 300 mg intravenously, and his condition was stable after 3 times of medication. One month later, the patient developed mucinous bloody stool again, and enteroscopy showed ulcerative colitis (active phase). The patient received infliximab 300 mg intravenously once every 8 weeks and azathioprine 50 mg once daily orally. After 23 days of treatment, the patient developed persistent pain in the upper abdomen, serum amylase was 411 U/L, blood lipase was 1 415 U/L, and serum pancreatic amylase was 374 U/L. Abdominal CT showed acute pancreatitis, which was considered to be related to azathioprine. Seven days after discontinuation of azathioprine and treatment with fasting, acid suppression, anti-infection, and pancreatic secretion inhibition, his symptoms were relieved, and serum amylase and lipase levels returned to normal. One month later, the patient took azathioprine orally again according to the original dose by himself, and the symptoms of acute pancreatitis reappeared 6 hours later. The drug was stopped and the above treatments were given. Five days later, the patient′s symptoms were relieved, and the blood routine examination and serum amylase returned to normal.

Objective:To evaluate the rehabilitation efficacy of early mobilization based on collaboration care model for patients with laparoscopic colorectal surgery.Methods:Cluster sampling method was used in the department to recruit colorectal cancer patients with laparoscopic surgery. The control group (49 cases) received routine perioperative care and exercise, and the intervention group (47 cases) received the coordinated early mobilization combined with routine perioperative care and exercise, from January to March 2019. Primary outcome were health status and the proportion of patients returning to preoperative functional walking capacity (6-min walk test) at 4 weeks after surgery. The in-hospital mobilization (time out-of-bed), time to achieve discharge criteria, time to recover gastrointestinal function and complication rate were explored.Results:In intervention group,89.4%(42/47) of patients achieved mobilization target on 4 days after surgery compared with 42.6%(20/47) on the day of surgery. Time out of bed were greater in the intervention group compared with the control group, and there were differences between the two groups( Z values were -8.437--7.381, P<0.01). Time to recover gastrointestinal function and the recovery of energy on 3 days after surgery were (58.74±17.41) h, (59.02±9.46) points in the observation group, and (71.82±21.53) h, (62.61±7.68) points in the control group, and there were significant differences between the two groups ( t values were -3.263, -2.046, P<0.05). But other outcome measures were not different between the two groups ( P>0.05). Conclusions:For colorectal laparoscopic surgery patients, the coordinated early mobilization improved the adherence to ambulation, in-hospital mobilization, time to recover gastrointestinal function and recovery of energy to promote rehabilitation.

Objective:To explore the real return-to-work experiences and expectations of young and middle-aged stroke patients in community, in order to provide reference for the formulation of the support plan for returning to work from the perspective of patients, and further promote their return to work.Methods:Using the phenomenological method of qualitative research, 11 young and middle-aged stroke patients in Zhengzhou community from April to May, 2019 were interviewed in a semi-structured way, then the interview data were analyzed and the theme was extracted.Results:The community young and middle-aged stroke patients return-to-work experiences and expectations included the following five themes: uncertain return-to-work belief, limited work-related ability, complex inner feelings in the process of returning to work, insufficient external support and expectation of returning to work after stroke (The desire to return-to-work, expectation to get support and help related to returning to work).Conclusions:In order to promote young and middle-aged stroke patients in community to return to work, the three-way interaction mode of community-society-workplace should be considered from the aspects of patients' personal and external support to help patients recover actively, establish beliefs, reduce negative emotions, and further promote patients to return to work.

Objective: To investigate the situation and influencing factors of bowel cleansing in patients before colonoscopy, and to provide reference for guiding patients′ bowel preparation. Methods: The clinical data of 421 patients undergoing electronic colonoscopy in the endoscopy center of the second people′s hospital of Lu′an city in Anhui Province from April to September 2018, Prospective collection by systematic sampling, including general data of patients, clinical data of bowel preparation and score of Boston bowel preparation scale. Univariate analysis and logistic regression analysis were performed on the relevant factors of bowel preparation. Results: Among the 421 patients, 52 cases were not eligible for intestinal cleaning, and the unqualified rate was 12.35%(52/421). Logistic regression analysis showed that: Total amount of drinking water prepared for intestinal tract before colonoscopy (OR=1.674, P=0.018),The total times of defecations after taking the drug (OR=1.270, P=0.014), the characteristics of last stool before colonoscopy (OR=2.211, P=0.042), the diet the day before colonoscopy (OR=0.553, P=0.006) , body mass index (OR=1.111, P=0.042), and intestinal diseases (P=0.022), were all intestinal clearance independent influencing factors of cleaning effect; While took laxative type (mannitol/PEG), drunk water speed (within 3 hours), first defecation time, the site of drinking bowel-clearing drugs, daily activity, none of the above factors affected the bowel preparation effect (P>0.05) . Conclusion Before colonoscopy, there were many factors affecting the cleaning effect of the intestine. The total water intake of intestinal preparation was less than 2 000 ml, the total number of defecation after taking medicine was less than 5 times, the last defecation contained residue, the day before the examination was strictly fasting, the body mass index was less than 18.5 kg/m², and colitis, enterelcosis and occupying lesion are independent risk factors for intestinal cleaning. Attention should be paid to the comfort care and guidance of intestinal preparation, and prospective intervention can effectively improve the cleaning effect of intestinal tract.
