ObjectiveTo explore the mechanism of Huanglian Wendantang on damp-heat type diabetes enteropathy rats based on the G protein coupled bile acid receptor 5/glucagon like peptide-1 （TGR5/GLP-1） signaling pathway and intestinal flora. MethodsA total of 72 male Sprague Dawley （SD） rats were adaptively fed for one week. Twelve SD rats were randomly selected as a blank group and fed with an ordinary diet. The rest of the SD rats were fasted for 12 hours without water. A rat model with damp-heat type diabetes enteropathy was made by left intraperitoneal injection of streptozotocin （55 mg·kg^-1） and high sugar and high fat diet （20% sucrose solution + high fat diet） in a humid and hot environment （artificial climate box： temperature 30-34 ℃， relative humidity： 85%-95%）. After successful modeling， the rats were randomly divided into a model group， a metformin group （200 mg·kg^-1）， low-dose， medium-dose， and high-dose Huanglian Wendantang groups （7.10， 14.20， 28.39 g·kg^-1）， with 12 rats in each group. The normal group and the model group were orally administered with physiological saline once a day for 6 consecutive weeks. During the observation period， the weight and blood glucose levels of rats were measured and recorded weekly. After the administration， fresh feces were collected from rats， and 16S rRNA sequencing technology was used to study the differences and changes in intestinal flora among different groups. The levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） in the serum of rats were detected by enzyme-linked immunosorbent assay （ELISA）， and the pathological morphological changes of colon tissue were examined. The expression of TGR5 and GLP-1 in colon tissue was detected by immunohistochemistry， and the expression of TGR5 and GLP-1 proteins in colon tissue was measured by Western blot. ResultsCompared with the blank group， the model group showed a decrease in body weight， an increase in blood glucose， and significant damp-heat symptoms. The levels of IL-6 and TNF-α in serum were significantly increased （P<0.01）. The expression of TGR5 and GLP-1 was decreased （P<0.01）， and the pathogenic bacteria were increased. Compared with the model group， the treatment groups exhibited improvements in body weight， blood glucose levels， and damp-heat syndrome in rats. Among them， the high-dose group of Huanglian Wendantang displayed the most significant improvement effect， with significantly reduced inflammation levels （P<0.01） and elevated expression of TGR5 and GLP-1 （P<0.01）. Colonic pathological sections showed that Huanglian Wendantang could effectively ameliorate colonic pathological changes. The 16S rRNA sequencing result indicated a significant increase in beneficial bacteria in the treatment groups. ConclusionHuanglian Wendantang can effectively ameliorate the damp-heat symptoms and blood glucose levels in rats with damp-heat type diabetes enteropathy， and it may exert an effect by regulating the TGR5/GLP-1 signaling pathway and intestinal flora disorder.

Objective:To investigate the medical narrative competence of pediatric staff, and analyze its influencing factors and correlation with psychological resilience, and to discuss strategies to improve narrative competence.Methods:From January 11 to February 25, 2022, by convenience sampling, we sampled pediatric personnel and those on refresher training at Children's Hospital, Zhejiang University School of Medicine for a questionnaire survey involving general information, the narrative competence scale, and the 14-item resilience scale. With the use of SPSS 26.0, the narrative competence of different populations was compared, and factors affecting narrative competence were determined through Pearson correlation analysis and multiple regression analysis.Results:A total of 361 valid questionnaires were included in this study, and there was significant differences in the narrative competence score between different ages, professional titles, working years, income levels, and whether they wrote parallel charts ( P<0.05). The total score of narrative competence of pediatric staffs was (147.13±18.76), and positively correlated with the total resilience score and the score of each dimension ( P≤0.001). The regression analysis showed that writing parallel charts and resilience could explain 53.10% of the variation in narrative competence ( P<0.001). Conclusions:Pediatric staff's narrative competence is at low or intermediate levels. Parallel chart writing and resilience training can improve narrative competence and promote a harmonious doctor-patient relationship.

Objective:To investigate the clinicopathological characteristics of gastrointestinal tumors with SWI/SNF complex deficiency and to perform a prognostic analysis of the patients.Methods:Gastrointestinal tumor cases with SWI/SNF complex deficiency expression diagnosed at the Department of Pathology, Zhongshan Hospital, Fudan University, Shanghai, China from August 2021 to May 2023 were collected. Hematoxylin and eosin (HE) stained slides were reviewed, and immunohistochemical results were analyzed. Clinical and pathological information was recorded, and relevant literature was reviewed.Results:A total of 36 cases of gastrointestinal tumor with loss of SWI/SNF complex expression were identified, including 28 males (77.8%) and 8 females (22.2%). The average age at diagnosis was 70 years (range 48-85 years). Clinical staging showed 3 cases in stage Ⅰ (8.3%), 12 cases in stage Ⅱ (33.3%), 19 cases in stage Ⅲ (52.8%), and 2 cases in stage Ⅳ (5.6%). Complete or partial loss of ARID1A expression was observed in 20 cases (55.6%); complete or partial loss of SMARCA2 expression was observed in 24 cases (66.7%). SMARCA4 exhibited complete loss of expression in 4 cases (11.1%). Eleven cases (30.6%) showed concurrent complete or partial losses of both ARID1A and SMARCA2 expression. Twelve cases (33.3%) had mismatch repair protein deficiency, all of which were characterized by MLH1/PMS2 absence. Mismatch repair protein deficiency was associated with loss of ARID1A expression ( P<0.01). Patients with mismatch repair protein deficiency were also associated with earlier clinical stage and a lower risk of lymph node metastasis compared to the ones with intact mismatch repair proteins ( P<0.05). Conclusions:SWI/SNF complex deficiency in gastrointestinal tumors is associated with dedifferentiation and often accompanied by mismatch repair protein deficiency. Compared to the cases with intact mismatch repair proteins, the cases with defective mismatch repair protein have an earlier clinical stage and a lower risk of lymph node metastasis.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

The search time limit was from the establishment of the database to August 31, 2022.Results:A total of 14 articles were included, including six guidelines, three RCTs, three systematic reviews, and two clinical decisions. A total of 8 themes and 27 best evidence were extracted.Conclusions:It is recommended that clinical medical and nursing personnel provide personalized and multimodal procedural pain intervention measures for adult patients in ICU in a timely manner in accordance with the medication principles of procedural pain management, in order to improve the procedural pain experience of ICU patients and the quality of nursing.

Objective To simulate the process of thrombus removal from the open-type stent retrievers, so as to provide theoretical references for the design and clinical application of the open-type stent retrievers. Methods Finite element models of the open-type stent retrievers with 3,4,5 supporting units (K3,K4,K5), the crimping tools, simulated vessels and simulated thrombus (three types) were established. Radial displacement load was applied on the crimping tool until the stent was crimped to 0.5 mm, and the maximum principal strain (MPS) peak and radial force (RF)of the stent were analyzed. When displacement of the crimping tool was restored, the stent self-expanded and contacted with blood vessels, and MPS of the stent and von Mises stress (VMS) of blood vessels were analyzed. Axial displacement was applied to proximal end of the stents to allow the stent to drive the clots to migrate, and the blood vessel VMS and withdrawal force of the stents (the ability to capture thrombus) were analyzed. ResultsThe MPS peaks for 3 types of stent retrievers during crimping process were 6.94%, 8.30% and 5.48%, which were all smaller than the 12% fracture limit. When the outer diameter of the stent was 3 mm (equal to the inner diameter of blood vessels), the K4 stent had the largest RF. The results of self-expanding release process showed that the larger the number of support units, the greater the VMS of blood vessels. At the stage of thrombus migration and removal,the VMS of blood vessels was generally small and concentrated on the thrombus. The withdrawal force of the stent reached the maximum at the initial stage of thrombus migration and removal, then gradually decreased. The peak withdrawal force of the K4 stent was larger than that of the K5 and K3 stent. Conclusions Although the MPS and VMS for 3 types of open-type stent retrievers were within the safe range, the K4 stent showed better performance in RF and withdrawal force with the three types of thrombus. The research findings can provide the analysis methods and ideas for optimizing the open-type stent retrievers, to avoid clinical complications such as vascular injury and improve safety and effectiveness of the stent retrievers.

Background: Cardiopulmonary resuscitation (CPR) strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest. During CPR, both healthcare and non-healthcare workers who provide resuscitation are at risk of infection. The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients. Main recommendations: 1) A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs. 2) Psychological counseling and treatment are highly recommended, since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest. 3) Healthcare workers should wear personal protective equipment (PPE). 4) Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19. 5) Hands-only chest compression and mechanical chest compression are recommended. 6) Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early. 7) CPR should be provided for 20-30 min. 8) Various factors should be taken into consideration such as the interests of patients and family members, ethics, transmission risks, and laws and regulations governing infectious disease control. Changes in management: The following changes or modifications to CPR strategy in COVID-19 patients are proposed: 1) Healthcare workers should wear PPE. 2) Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols. 3) Both the benefits to patients and the risk of infection should be considered. 4) Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.

Legumain, also called asparaginyl endopeptidase, is one new member of the cysteine protease C13 family and plays various roles in human. In recent years, studies have displayed that Legumain is over expressed in a variety of tumors types and promotes the proliferation of tumor cells, tumor invasion and metastasis as well as angiogenesis through varied mechanisms. Further investigation of Legumain will be helpful to elucidate the pathogenesis and progression mechanism of malignant tumors and provide new molecular for targeted therapy of tumors.

Objective:To explore the effectiveness and safety of holmium laser treatment via flexible bronchoscopy in children with tracheobronchial tuberculosis (TBTB).Methods:The clinical data of 40 children with TBTB admitted in Qilu Children′s Hospital of Shandong University from February 2016 to June 2019 were retrospectively analyzed. According to the treatment approach, they were divided into conventional treatment group (20 cases) and holmium laser treatment group (20 cases). The sex, age, course of disease and lesion location before treatment, and the time till relief of atelectasis and airway obstruction after treatment were compared between the two groups with t test and χ 2 test. Results:Among the 40 cases, 24 were males and 16 females, and 35 had lymph node fistula (87.5%) and 5 had granulation proliferation (12.5%). There was no statistically significamt difference between the conventional group and laser group in sex (male ratio: 50%（10/20） vs. 75%（15/20）, χ 2=2.66, P=0.10), age （(3.2±2.2） years vs. （2.2±1.8） years, t=1.41, P=0.16), course of disease (<1 month ratio: 30%（6/20） vs. 35%（7/20）, χ 2=0.11, P=0.73), lesion location (single lesion ratio： 45%（9/20） vs. 60%(12/20), χ 2=0.90, P=0.34). The effectiveness was evaluated after 3 months, and the total effective rate were 100% in laser group and 40% in conventional group, the difference was significant (χ2=25.34, P<0.01). No serious adverse events occurred in the two groups during the observational period. Conclusions:Holmium laser treatment via bronchoscopy is an effective way to remove the tuberculosis foci in the trachea, which can reduce the incidence of further related complications, and could be applied in clinical approach.
