Myocardial fibrosis is a serious cause of heart failure and even sudden cardiac death. However, the mechanisms underlying myocardial ischemia-induced cardiac fibrosis remain unclear. Here, we identified that the expression of sterile alpha and TIR motif containing 1 (SARM1), was increased significantly in the ischemic cardiomyopathy patients, dilated cardiomyopathy patients (GSE116250) and fibrotic heart tissues of mice. Additionally, inhibition or knockdown of SARM1 can improve myocardial fibrosis and cardiac function of myocardial infarction (MI) mice. Moreover, SARM1 fibroblasts-specific knock-in mice had increased deposition of extracellular matrix and impaired cardiac function. Mechanically, elevated expression of SARM1 promotes the deposition of extracellular matrix by directly modulating P4HA1. Notably, by using the Click-iT reaction, we identified that the increased expression of ZDHHC17 promotes the palmitoylation levels of SARM1, thereby accelerating the fibrosis process. Based on the fibrosis-promoting effect of SARM1, we screened several drugs with anti-myocardial fibrosis activity. In conclusion, we have unveiled that palmitoylated SARM1 targeting P4HA1 promotes collagen deposition and myocardial fibrosis. Inhibition of SARM1 is a potential strategy for the treatment of myocardial fibrosis. The sites where SARM1 interacts with P4HA1 and the palmitoylation modification sites of SARM1 may be the active targets for anti-fibrosis drugs.

Background/Aims: The shortage of donor liver hinders the development of liver transplantation. This study aimed to clarify the poor outcomes of functionally marginal liver grafts (FMLs) and provide evidence for the improvement of ischemia-free liver transplantation (IFLT) after FML transplantation. Methods: Propensity score matching was used to control for confounding factors. The outcomes of the control group and FML group were compared to demonstrate the negative impact of FMLs on liver transplantation patients. We compared the clinical improvements of the different surgical types. To elucidate the underlying mechanism, we conducted bioinformatic analysis based on transcriptome and single-cell profiles. Results: FMLs had a significantly greater hazard ratio (HR: 1.969, P=0.018) than did other marginal livers. A worse 90-day survival (Mortality: 12.3% vs. 5.0%, P=0.007) was observed in patients who underwent FML transplantation. Patients who received FMLs had a significant improvement in overall survival after IFLT (Mortality: 10.4% vs 31.3%, P=0.006). Pyroptosis and inflammation were inhibited in patients who underwent IFLT. The infiltration of natural killer cells was lower in liver grafts from these patients. Bulk transcriptome profiles revealed a positive relationship between IL-32 and Caspase 1 (R=0.73, P=0.01) and between IL-32 and Gasdermin D (R=0.84, P=0.0012). Conclusions FML is a more important negative prognostic parameter than other marginal liver parameters. IFLT might ameliorate liver injury in FMLs by inhibiting the infiltration of NK cells, consequently leading to the abortion of IL-32, which drives pyroptosis in monocytes and macrophages.

Objective:To analyze the influencing factors of the public hospital′s WeChat official accountcommunication effect, for references for improving the public hospital′s WeChat official account′s public opinion guidance in health dissemination field.Methods:The communication data of all the tweets on the official account of a tertiary hospital from 2018 to 2021 were obtained, taking the tweets reading times as the evaluation index of the communication effect of the WeChat official account. The number of sharing times, the number of title words, punctuation points, the first launch platform and content type were took as factors that may affect comounication effectiveness for single factor analysis and multiple linear regression analysis.Results:A total of 1 102 tweets were included, with an average reading times of 10 670, and an average sharing times of 411. The top 10 tweets in terms of reading times were mainly about the treatment of major diseases, emergencies, common misconceptions and health popular science. The sharing times and the hand-painted entries were positively correlated with the reading times( P<0.05), while the number of title words and punctuation was negatively correlated with the reading times( P<0.05). The reading times of tweets varied with different title sentence structures, initial platforms, source departments, and content types, and the differenceswere statistically significant( P<0.05). The sharing times, hand-painted entries, title sentence structures and content typeswere the influencing factors of the public hospital′s WeChat official account communication effect( P<0.05). Conclusions:The tweets of a public hospital′s WeChat official account with high reading times focused on the hot issues that people pay attention to, and there were many factors influencing the communication effect. The author suggested that the WeChat official account of public hospitals should focus on the needs of the people, promote the construction of high-quality content, and further strengthen the design level of copywriting to improve its audience and communication power.

OBJECTIVE To understand the current status of research on traditional Chinese medicine（TCM） human resources， and to provide a reference for expanding research ideas on TCM human resources and promoting the construction of TCM talents. METHODS From January 1， 2000 to December 31， 2022， literature related to TCM human resources was collected from the three major databases of CNKI， Wanfang and VIP. Using CiteSpace 5.8 R3 software， visualization analysis was performed for the literature in terms of publication time， journal sources， authors， institutions and areas， funding， research content， keywords， etc. RESULTS A total of 324 literature related to TCM human resources in China were included， and the number of literature issued showed an upward trend， with an annual average of 14.09 literature； 161 kinds of journals were involved， core journals accounted for 18.21% of the total publication volume； a total of 23 authors had published 2 or more literature， with a total of 55 literature published （16.98%）； a total of 416 institutions were involved， mainly schools （66.83%）； 60.49% of the literature were supported by the fund. The majorities of 324 literature were survey studies （170 literature）， and most of them used self-designed questionnaires （55 literature）； the high-frequency keywords included talent training， human resources， TCM， etc. The keywords were clustered into 7 categories， such as “human resources“”talent training“”TCM industry“”TCM services“”talent training models” “fairness” and “TCM talents”. The main problems described in the literature included insufficient talent， lack of reasonable distribution of regional structure， lack of reasonable plans for talent training， and insufficient professional knowledge and abilities. Continuously cultivating high-level talents and improving employment conditions in areas with severe human resource loss were the corresponding countermeasures proposed in the literature. CONCLUSIONS The research on TCM human resources starts late but has developed rapidly overall， and the quality of research needs to be improved； the structure of research team is single and unevenly distributed geographically； there is a structural imbalance in the allocation of human resources， as well as problems such as a shortage of professional talents， low levels of education and training and incomplete development systems.

ObjectiveTo investigate the effect of anodal transcranial direct current stimulation (atDCS) combined with contralaterally controlled functional electrical stimulation (CCFES) on upper limb motor function of stroke patients. MethodsFrom January to December, 2022, 60 stroke patients from Zhejiang Provincial People's Hospital were randomly divided into atDCS group (n = 20), CCFES group (n = 20) and combined group (n = 20). All the groups accepted routine rehabilitation, while atDCS group accepted atDCS on the primary motor (M1) area of the damaged hemisphere, CCFES group accepted CCFES on the triceps brachii and extensors carpi muscles, and the combined group accepted atDCS on the M1 area of damaged hemisphere and CCFES on triceps brachii and extensors carpi muscles, for six weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Wolf Motor Function Test (WMFT), and the electromyography root mean square (RMS) ratio of bilateral triceps brachii muscles and extensor carpi muscles, before and after treatment. ResultsThe FMA-UE score, WMFT score, and the RMS ratio of the triceps brachii muscles and extensor carpi muscles improved in all the groups after treatment (|t| > 5.007, P < 0.001), and improved the most in the combined group (F > 14.492, P < 0.001). ConclusionatDCS combined with CCFES can effectively improve upper limb motor function of stroke patients.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

Objective:To explore the feasibility of low-dose 4DCT scanning in simulation and target delineation for solitary pulmonary tumors (SPTs).Methods:23 patients with SPTs received 4DCT scanning simulation with the conventional scanning (CON), low voltage (LV), low current (LA) and low voltage combined with low current (LVA) in sequence. Based on the 4DCT images derived from the four sets of scanning parameters, the internal gross tumor volume (IGTV CON, IGTV V, IGTV A, IGTV VA) of SPTs were delineated and matched. Taking IGTV CON as reference, the tumor displacement and the centroid position of IGTV V, IGTV A and IGTV VA were compared with IGTV CON. The radiation doses under different scanning parameters were compared. Results:The volumes of IGTV CON, IGTV V and IGTV A were (12.26±12.30) cm 3, (12.21±12.16) cm 3 and (11.87±11.70) cm 3, respectively ( P=0.337). IGTV VA was (11.34±11.07) cm 3, significantly smaller than IGTV CON ( P=0.005). There was no significant difference in the centroid positions of IGTV CON, IGTV V, IGTV A and IGTV VA in three directions ( P=0.491, 0.360, 0.136). The Dice′s similarity coefficient (DSC VA) was significantly lower than DSC V and DSC A ( P=0.004, 0.030). The tumor displacement measured by the four sets of 4DCT images was similar in the LR direction ( P=0.470), and also in the AP direction ( P=0.108). For the displacement in the SI direction, LVA scanning was smaller than CON ( P=0.015). The radiation doses under four different scanning conditions were (397.0±140.3) mGy·cm, (175.0±61.8) mGy·cm, (264.8±95.3) mGy·cm and (116.8±41.2) mGy·cm, respectively ( P<0.001). Conclusions:LV or LA scanning exert no significant effect on the volume, centroid position of IGTV and the tumor displacement in 4DCT simulation for SPTs. The radiation dose that patients receive under LV and LV scanning is lower than that of CON. Consequently, LV or LA scanning is feasible in 4DCT simulation and target delineation for SPTs.

Objective:To analyze original medical humanities articles written by staff of the hospital and extract key elements of hospital culture for staff perception, for recommendations on homogenous development of multiple campuses of the hospital.Methods:Original medical humanities articles written by staff of the hospital were collected from the WeChat accounts, websites and printouts of a tertiary hospital in Beijing from January 2013 to December 2019, with text mining made by Python3.7; Bert and Tencent open-source 8 million Chinese word dataset were used as entity identification training dataset; K-Means cluster analysis was used to analyze and select cluster results of higher degree of fitting; TextRank was used to screen keywords of each clustered category. Significance of each category was summarized in the end based on keywords following the screening.Results:Among the 341 articles collected, high frequency words were work, hospital, patient, sick person, development, medicine, medical treatment, doctor, outpatient service and clinic. The words fell into ten categories: process recall, work attribute, work responsibility, diagnosis and treatment behavior, growth experience, team cooperation, professionalism, management innovation, doctor-patient communication and others.Conclusions:Research on hospital staff culture perception is conducive to identifying the cultural content of the hospital. In the homogenous development of multiple campuses of the hospital, it is imperative to nurture the staff′s sense of identify and belonging to the hospital, enhance their sense of gain and happiness, and strengthen the scientific management system centering on patients.

Objective:To understand the willingness of contracted residents to renew the family doctor contract service in Shandong Province, and to explore its influencing factors.Methods:From July to August 2020, 1 500 contracted residents in 3cities of Shandong Province were investigated by questionnaire survey.Descriptive statistical analysis, Mann-Whitney U test and binary logistic regression model were used to analyze the contracted residents′ cognition, utilization, satisfaction evaluation and renewal intention of family doctor contract service. Results:1 445 valid questionnaires were obtained, of which 682(47.2%)were willing to renew their contracts.The results of binary logistic regression analysis showed that marital status, educational level, time to see a doctor in contracted institutions, optimism about the development prospect of contracted service policy, whether the proportion of medical insurance reimbursement increased after signing the contract, whether follow-up work was carried out on time, satisfaction with family doctor service attitude and satisfaction with the effect of disease treatment were factors affecting the willingness of contracted residents to renew the contract.Conclusions:The contracted residents in Shandong Province have a high willingness to renew their contracts. On the basis of consolidating and improving the policy cognition and confidence of the contracted residents, we should actively optimize and improve the contracted service quality, ensure the sense of service access of contracted residents, and continuously and effectively realize the comprehensive promotion of the contracted services of family doctors.

Atherosclerosis(AS), characterized with the accumulation of lipids on the vessel wall, is an immune-related inflammatory disease which promotes the progression of cardiovascular diseases(CVD). The imbalance of Treg/Th17 accelerates the progression of AS. Yangyin Huoxue Prescription(YHF)is an efficient traditional Chinese medicine used in the treatment of AS, but the effects of YHF on the balance of immunity have still not been clarified. This project was designed to investigate the effects of YHF on the imbalance of Treg/Th17 and AS in ApoE-/- mice induced by high-fat diet(HFD). ApoE-/- mice were given HFD to induce AS and administered low-dose YHF(18 g/kg)or high-dose YHF(36 g/kg)for 20 weeks. Atherosclerotic plaque area was analyzed by oil red O staining. Serum lipids were measured by biochemical kits. Treg or Th17 cells in peripheral blood were detected by flow cytometry. mRNA and protein expression of Foxp3 and RORγt of aortas were determined by qRT-PCR, Western blot and immunohistochemistry. Splenic CD4+T cells of mice were isolated and activated by anti-CD3/CD28, and then treated with lipopolysaccharide(LPS)and YHF. The expression of mRNA and protein of Foxp3 and RORγt were detected by qRT-PCR and immunofluorescence. It was found that YHF reduced the plaque area, decreased lipid level and increased the ratio of Treg cells in peripheral blood. Moreover, YHF increased mRNA or protein expression of Foxp3 in aortas in vivo or CD4+T cells in vitro while decreasing mRNA or protein expression of RORγt. These results suggested that YHF can regulate the imbalance of Treg/Th17 in ApoE-/- mice induced by HFD, and reduce the inflammatory stimulation of LPS on CD4+T cells, thereby improving AS.
