Periodontitis is a common oral disease characterized by progressive alveolar bone resorption and inflammation of the periodontal tissues. Dimethyl fumarate (DMF) has been used in the treatment of various immune-inflammatory diseases due to its excellent anti-inflammatory and antioxidant functions. Here, we investigated for the first time the therapeutic effect of DMF on periodontitis. In vivo studies showed that DMF significantly inhibited periodontal destruction, enhanced mitophagy, and decreased the M1/M2 macrophage ratio. In vitro studies showed that DMF inhibited macrophage polarization toward M1 macrophages and promoted polarization toward M2 macrophages, with improved mitochondrial function, inhibited oxidative stress, and increased mitophagy in RAW 264.7 cells. Furthermore, DMF increased intracellular mitochondrial Tu translation elongation factor (TUFM) levels to maintain mitochondrial homeostasis, promoted mitophagy, and modulated macrophage polarization, whereas TUFM knockdown decreased the protective effect of DMF. Finally, mechanistic studies showed that DMF increased intracellular TUFM levels by protecting TUFM from degradation via the ubiquitin-proteasomal degradation pathway. Our results demonstrate for the first time that DMF protects mitochondrial function and inhibits oxidative stress through TUFM-mediated mitophagy in macrophages, resulting in a shift in the balance of macrophage polarization, thereby attenuating periodontitis. Importantly, this study provides new insights into the prevention of periodontitis.

Objective:To translate the Needs and Provision Complexity Scale (NPCS) into Chinese and validate its reliability and validity among stroke patients.Methods:The Chinese version of NPCS was developed through forward translation, back-translation, cultural adaptation, and pre-survey using the modified Brislin translation model. Convenience sampling was used to select 330 stroke patients who visited Shanghai Tenth People's Hospital between May and July 2024 for questionnaire surveys, thereby validating the reliability and validity of the scale. A total of 330 questionnaires were distributed, with 316 valid responses collected for the need version and 305 valid responses collected for the provision version.Results:The Chinese version of NPCS was divided into a need version and a provision version, each comprising two dimensions and 15 items. The content validity index at the item level of the need and provision version of the scale ranged from 0.833 to 1.000, with an average content validity index of 0.943 for both. The Cronbach's α coefficients of the scale were 0.916 and 0.918, and the Cronbach's α coefficients of each dimension were from 0.882 to 0.919, and the test-retest reliability coefficients were 0.913 and 0.897, respectively. Exploratory factor analysis yielded two common factors of personal health care and social support, with cumulative variance contribution rates of 71.437% and 70.266%, respectively. The Chinese version of the scale demonstrated good model fit.Conclusions:The Chinese version of NPCS has good reliability and validity, and can be used for investigating the provision and need of rehabilitation and social support services for stroke patients.

Objective:To explore the health education needs of patients undergoing fecal microbiota transplantation (FMT) at different stages of treatment.Methods:A qualitative research method was employed and an interview guide based on timing theory was developed. Semi-structured interviews were conducted with patients treated for colorectal conditions with FMT at Tenth People's Hospital of Tongji University from August to October 2022. Data from the interviews were analyzed using thematic analysis.Results:A total of 19 patients aged 20 to 65 were interviewed, including seven males and 12 females. A total of five main themes and 15 subthemes were identified: health education demands during the diagnosis phase (basic information about FMT; knowledge about donor screening), health education demands during the preparation phase (alleviating discomfort caused by nasoenteric tubes; interpretation of examination reports), health education demands during the execution phase (dietary guidance during FMT; exercise guidance during FMT; medication and supplementary training guidance; management of adverse reactions), health education demands during the adaptation phase (consolidating treatment effects; knowledge related to FMT capsules; post-discharge follow-up content and methods; post-discharge precautions), long-term health education demands (diverse health education tools; individualized health education approaches; alleviating psychological anxiety) .Conclusions:Patients undergoing FMT have numerous concerns, and diverse health education needs throughout the treatment process. Healthcare professionals should adopt various health education strategies to address these needs.

Objective To systematically review whether mirror therapy(MT)intervention can effectively improve upper extremity motor function and activities of daily living(ADL)in stroke patients;whether its improvement is affected by pa-tients'age and disease course;and whether MT's influencing factors,such as intervention period,time,and fre-quency,have a dosage effect on upper extremity motor function and ADL. Methods Seven databases were searched,including Embase,Web of Science,PubMed,Cochrane Library,Wanfang data,VIP and CNKI from establishment to April,2023,and randomized controlled trials of MT for upper extremity motor function and ADL in stroke patients were screened.Quality assessment was performed using Physiothera-py Evidence Database(PEDro).Meta-analysis was performed using RevMan 5.4.1,and network meta-analysis was performed using R software,reticulated meta-analysis tables and cumulative probability tables were drawn for ranked comparisons,and funnel plots were drawn to test for publication bias of the outcome indicators using Stata 17.0 software.GRADE was used to evaluate the quality of evidence for the outcome indicators. Results A total of 13 papers(532 patients)were included.The PEDro score ranged from 6 to 8.Most of the literature did not report the blinding completely or did not implement allocation concealment,which might have some limita-tions.MT could improve the scores of Fugl-Meyer Assessment-Upper Extremities(n = 466,MD = 6.05,95%CI 3.44～8.66,P<0.001),Barthel index(n = 230,MD = 9.95,95%CI 6.23～13.68,P<0.001)and Functional Inde-pendence Measure(n = 147,MD = 4.17,95%CI 2.61～5.72,P<0.001)in stroke patients.Network meta-analysis showed that MT was more effective in upper limb motor function intervention for stroke patients aged 40 to 59 years with a disease course less than three months;and an intervention period less than four weeks,single inter-vention time less than 30 minutes,intervention duration daily more than 30 minutes and intervention twice daily might optimize the effects on upper limb motor function. Conclusion MT is effective on upper limb motor function and ADL in stroke patients,and the effect on upper limb mo-tor function is affected by the age and disease course of the patients,as well as the period,time and frequency of intervention.

Objective To compare anesthetic effects between erector spinae plane block(ESPB)and intercostal nerve block(ICNB)in thoracoscopic lung wedge resection guided by surgical pleth index(SPI).Methods A total of 46 patients who underwent thoracoscopic lung wedge resection in Wenzhou People's Hospital from July 2020 to June 2022 were selected and divided into ICNB group and ESPB group according to random number table method,with 23 cases in each group.Remifentanil infusion rate,propofol dosage and intraoperative vital signs were compared between two groups.Results The intraoperative remifentanil infusion rate in ESPB group was significantly lower than that in ICNB group(P<0.05).There was no significant difference in intraoperative propofol dosage between two groups(P>0.05).The SPI,bispectral index and mean arterial pressure in ESPB group during lung wedge resection were significantly lower than those in ICNB group(P<0.05).There was no significant difference in heart rate between two groups(P>0.05).Conclusion Under the guidance of SPI,patients undergoing thoracoscopic lung wedge resection with preoperative ESPB had low opioid consumption and stable vital signs.

Objective To systematically evaluate the predictive value of controlling nutritional status(CONUT)score for short-term neurological function and clinical outcome of stroke.Methods Cochrane library,PubMed,Web of Science,Embase,CNKI,Wan-fang,VIP,and CBM were searched by computer to find studies on the use of CONUT score to evaluate the nutritional status and follow-up of stroke patients from the establishment of the database to April 11,2023.Literature was searched and screened independently by two researchers.The Newcastle-Ottawa scale(NOS)was used to evaluate the quality of the included studies.Stata 15.Osoftware was used for Meta-analysis.Results A total of 12 literatures were included,all of which were high quality.Meta-analysis results showed that high CONUT score(≥2)was strongly associated with poorer functional outcomes(OR=1.41,95％CI:1.25-1.60,P＜0.001,I2=49.4％),and associated with increased mortality(OR=2.85,95％CI:2.03-4.00,P＜0.001,I2=0)increase.Conclusion High CONUT score may be a predictor of neurological recovery status and survival outcome in patients after stroke,and the prognostic mechanism of CONUT score in stroke patients is unclear and needs to be confirmed by further studies.

Objective:To explore the journey map of patients with chronic constipation during fecal microbiota transplantation.Methods:This study adopted phenomenological methods. From October to December 2023, purposive sampling was used to select chronic constipation follow-up patients who underwent fecal microbiota transplantation at the Intestinal Microecology Center of Shanghai Tenth People's Hospital as respondents for semi-structured interviews. Colaizzi 7-step analysis method and NVivo 11.0 software were used for data analysis.Results:A total of 15 interviewees were interviewed. During fecal microbiota transplantation, the journey map of constipation patients included stages, mood changes, touchpoints, themes, emotional experiences and opportunities. The patient's experience and needs were summarized into three themes and ten sub-themes, including pre-transplant adaptation disorders to new environments (unfamiliarity and confusion-admission coordination disorders, anxiety and expectations-diverse complex emotions, puzzle and helplessness-asymmetric doctor and patient information), effectiveness-related psychological and social experiences in transplantation (attention and expectations-longing for positive efficacy, perception of benefits and risk avoidance, shame and inferiority-treatment stigmatization experience, questioning and despair-unrealized expectations, treatment resistance-sensitive economic burden), post-transplant transition dilemmas (inaccessible medical services-lack of continuous treatment and nursing, disease recurrence troubles) .Conclusions:This study visualizes the experiences and needs of constipation patients during microbiota transplantation through a patient journey map and identifies multidimensional issues and needs of patients. Clinical medical and nursing staff should pay attention to the needs of patients at different stages of the treatment process when formulating intervention programs to improve the quality of fecal microbiota transplantation nursing.

Objective To explore the dilemmas faced by surrogate decision-makers of severe stroke patients in treatment decision-making,and to provide a basis for developing decision support strategies.Methods From April to December 2023,through phenomenological qualitative research with 16 surrogate decision-makers with severe stroke patients from ICU of the department of neurology in a tertiary hospital in Jing'an District,Shanghai.semi-structured in-depth interviews were used to examine the perceptions of decision-making on surrogate.Data were analyzed via Braun's style of thematic analysis.Results 4 themes and 10 sub-themes were identified.Theme 1:negative emotional dilemmas(urgent decision-making leads to anxiety,fear,and unknown stroke trajectory increases the sense of uncertainty).Theme 2:supportive environment dilemmas(lack of information support delays decision-making;lack of family support increases decision-making stress;insufficient economic support increases the burden of decision-making).Theme 3:the dilemma of weighing the pros and cons(difficult trade-offs between risk and reward,tough decisions between reality and ethics,conflicting choices of life and dignity).Theme 4:preference management dilemmas(practical difficulties in adhering to patient preferences,impediments to decision-making due to unknown patient preferences).Conclusion Surrogate decision-makers of severe stroke patients face multiple decision-making dilemmas.Healthcare professionals should provide emotional support in multiple ways and comprehensive support to reduce the decision-making dilemmas experienced by surrogate decision-makers,as well as implement death education for surrogate decision-makers and promote advance care planning to reduce their decision-making stress.
