Objective:To evaluate the diagnostic value of intestinal tissue metagenomic next-generation sequencing (mNGS) in severe diarrhea following haploidentical allogeneic hematopoietic stem cell transplantation (allo-HSCT) .Methods:Sixteen patients who developed severe diarrhea or hematochezia after haploidentical allo-HSCT at the First Affiliated Hospital of Fujian Medical University (June 2023–August 2024) were enrolled. All underwent gastrointestinal endoscopy and mNGS for microbial detection. Clinical, endoscopic, pathological, and microbiological data were analyzed to evaluate the diagnostic value of mNGS and treatment outcomes following targeted therapy.Results:The study included 16 patients (12 males, 4 females; median age 32.5 years, range 3–60 years). Diarrhea occurred a median of 3.93 months post-transplant (range 1.63–10.40 months). Stool cultures were negative except for one case with Candida. One patient tested positive for Clostridium difficile antigen. Endoscopy revealed mucosal congestion, edema, erosion, and bleeding, with focal inflammation on pathology. mNGS detected pathogens in 87.5% (14/16) of cases, including mixed infections in 78.5% (11/14). Common pathogens were Klebsiella pneumoniae, Enterococcus faecium, Escherichia coli, Rhizopus microsporus, EBV, and CMV. Targeted treatment adjustments led to symptom improvement in 87.5% of patients.Conclusion:Allo-HSCT patients are prone to infectious diarrhea due to immunosuppression. Molecular analysis of endoscopic biopsy tissues using mNGS can accurately identify pathogens, guide targeted therapy, and improve clinical outcomes.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective To explore the impact of irregular shape of head CT hematomas on postoperative re-bleeding and prognosis of patients with spontaneous intracerebral hemorrhage(ICH)who undergo craniotomy for hematoma evacuation.Methods We retrospectively enrolled consecutive patients with ICH who underwent craniotomy for hematoma evacuation in the Department of Neurosurgery of the Second People's Hospital of Guiyang Affiliated to Guizhou Medical University from January 2019 to June 2024.Baseline and clinical data were collected form the patients,including age,gender,smoking history,drinking history,hypertension,diabetes,history of anticoagulant use,admission systolic and diastolic blood pressure,admission National Institutes of Health stroke scale(NIHSS)score,Glasgow coma scale(GCS)score,time from onset to the first head CT,neutrophil-to-lymphocyte ratio(NLR),and platelet-to-lymphocyte ratio(PLR).Admission head CT scans were used to assess hematoma shape(regular or irregular),hematoma location(basal ganglia,lobar,multifocal),hematoma volume,perihematomal edema volume,the presence of midline shift,and intraventricular extension.Volume of the hematoma was assessed 2 days after surgery.Postoperative re-bleeding is defined as an increase in the volume of the hematoma by 12.5 ml compared to the previous postoperative CT scan within 2 weeks after surgery,or the reappearance of high-density areas in the focal area of the head CT scan during follow-up after complete hematoma clearance.Conduct patients follow-ups via telephone at 6 months postoperatively to assess their modified Rankin scale(mRS)scores.The sliding dichotomy method was applied to define prognosis based on the patients' baseline characteristics and disease severity.The prognostic score was calculated using formula:10 × admission GCS score-age-0.64 × admission hematoma volume.A prognostic score＞27.672 was considered potentially favorable,while a score ≤ 27.672 was considered potentially unfavorable.For patients with a potentially favorable prognosis,an mRS score of 0-2 was defined as a good outcome,and a score of 3-6 as a poor outcome.For those with a potentially unfavorable prognosis,an mRS score of 0-3 was defined as a good outcome,and a score of 4-6 as a poor outcome.In the comparison of baseline and clinical data between patients with regular and irregular hematoma shapes,factors with P＜0.05 were included in propensity score matching(PSM)to adjust for confounding variables.A 1∶1 matching was performed using the nearest neighbor method with a caliper value set to 0.25.Variables with statistically significant differences between groups after PSM matching were included in the multivariate Logistic regression analysis to identify influencing factors for postoperative re-bleeding and poor prognosis in ICH patients undergoing craniotomy hematoma evacuation.The predictive value of irregular hematoma shape for postoperative rebleeding and poor prognosis in ICH patients was analyzed using receiver operating characteristic(ROC)curve analysis.Results(1)A total of 440 ICH patients were enrolled,including 342 males and 98 females,aged from 20 to 84 years with a mean age of(56±12)years.Statistically significant differences were observed in baseline and clinical data between patients with regular and irregular hematoma shapes before PSM,including age,admission GCS score,NIHSS score,NLR,proportion of patients with hematoma rupture into ventricles,preoperative hematoma volume,proportion of patients with midline shift,preoperative volume of hematoma surrounding edema,proportion of patients with hematoma located in multiple sites,and postoperative 2-day hematoma volume(all P＜0.05).After propensity score matching of these factors,298 ICH patients were included in the statistical analysis,comprising 228 males and 70 females,with an age range of 20 to 84 years and a mean age of(57±12)years.Following PSM,no statistically significant differences were observed in the baseline and clinical characteristics between patients with irregular and regular hematoma shapes(all P＞0.05).(2)After propensity score matching,28 patients experienced postoperative re-bleeding while 270 did not.Significant differences were observed between the two groups in the following factors:proportion of patients with a history of anticoagulant use,admission PLR,NLR,irregular hematoma shape,and hematoma volume at 2 days after operation(all P＜0.05).No statistically significant differences were found in the remaining baseline and clinical characteristics(all P＞0.05).Using postoperative re-bleeding as the dependent variable and incorporating factors with P＜0.05 from the univariate analysis as independent variables,multivariate Logistic regression analysis identified irregular hematoma shape(OR,2.821,95％CI 1.142-6.968,P=0.025)and larger hematoma volume at 2 days post-operation(OR,1.062,95％CI 1.026-1.099,P＜0.01)as independent risk factors for re-bleeding following intracranial hematoma evacuation in ICH patients.ROC curve analysis demonstrated that irregular hematoma shape predicted postoperative re-bleeding with an area under the curve(AUC)of 0.62,showing a sensitivity of 71.4％and a specificity of 52.2％.(3)After propensity score matching,174 patients had poor prognosis while 124 had good prognosis.Significant intergroup differences were observed in age,admission GCS score,NIHSS score,irregular hematoma shape,proportion of patients with hematomas located in the basal ganglia and cerebral lobes,and hematoma volume at 2 days post-operation(all P＜0.05).No statistically significant differences were found in the remaining baseline and clinical characteristics(all P＞0.05).Using poor prognosis as the dependent variable and incorporating factors with P＜0.05 from univariate analysis as independent variables,multivariate Logistic regression analysis revealed that advanced age(OR,1.039,95％CI 1.015-1.064,P=0.002),high admission NIHSS score(OR,1.068,95％CI 1.025-1.113,P=0.002),irregular hematoma shape(OR,2.675,95％CI 1.582-4.524,P＜0.01),and larger hematoma volume at 2 days post-operation(OR,1.033,95％CI 1.002-1.064,P=0.038)were independent risk factors for poor prognosis.Conversely,lobar hematoma location(OR,0.192,95％CI 0.073-0.504,P＜0.01)was identified as a protective factor.ROC curve analysis showed that irregular hematoma shape predicted poor prognosis after intracranial hematoma evacuation with an AUC of 0.61,demonstrating a sensitivity of 59.2％and specificity of 62.9％.Conclusion Irregular hematoma shape on head CT is an independent risk factor for both postoperative re-bleeding and poor prognosis in ICH patients undergoing craniotomy for hematoma evacuation.

Phosphatase and tensin-homolog deleted on chromosome 10 (PTEN) is an important cancer suppressor gene. Its pathogenic mutation leads to PTEN hamartoma tumor syndrome (PHTS), a rare syndrome also known as Cowden syndrome, which is relevant to early-onset hereditary breast cancer (BC). In this paper, we report three patients with unilateral multicentric BC and synchronous and metachronous bilateral BC who harbored PTEN gene mutations, and summarize the clinical manifestations, pathological characteristics, diagnosis, treatment and follow-up outcomes to provide reference for management of PTEN gene mutation-related BC among the Cowden syndrome population.

Objective:To analyze the impact of the implementation of the policy of centralized volume-based procurement of dental implant consumables on the prevention and control of corruption risk in public hospitals, and provide reference for improving the construction of corruption risk prevention and control in public hospitals.Methods:Develop a survey questionnaire for three entities: the Discipline Inspection Commission of public hospitals, dental implant doctors in public hospitals, and dental implant consumables distribution enterprises. The questionnaire content for the Discipline Inspection Commission of public hospitals mainly included the impact of the implementation of the policy of centralized volume-based procurement of dental implant consumables on the prevention and control of hospital integrity risks, as well as the development of supporting policies in hospitals; The questionnaire content for dental implant doctors mainly included their understanding of the centralized volume-based procurement policy, their communication with distribution companies, and their awareness of integrity; The questionnaire content for dental implant consumables distribution enterprises mainly included the situation of the distribution enterprises entering the centralized volume-based procurement catalog for implants, and the subsequent adjustment of business strategies.Using convenience sampling method, a questionnaire survey was conducted from February to June 2023 on the Discipline Inspection Commission of public hospitals in Zhejiang Province, dental implant doctors in public hospitals nationwide, and distribution enterprises of dental implant consumables in Zhejiang Province. Descriptive analysis was conducted on the questionnaire data.Results:Effectively collected 16 questionnaires filled out by the Discipline Inspection Commission leaders of public hospitals in Zhejiang Province. Among them, the Discipline Inspection Commission leaders of 11 public hospitals believed that the implementation of the policy of centralized volume-based procurement of dental implant consumables could reduce the existing corruption risks of public hospitals, 1 believed that it would create new corruption risks, and 4 believed that both aspects of the impact existed; 12 leaders believed that the policy′s strengthening of corruption risk prevention and control was mainly reflected in squeezing implant prices, reducing selection and procurement risks, and reducing red envelopes and kickbacks. 270 questionnaires from dental implant doctors in public hospitals were effectively collected. Regarding the implementation of the centralized volume-based procurement policy, 187 people believed that it would inhibit the development of the dental implant industry, 148 people expected their personal salaries to decrease, 78 people would participate more in lectures and training organized by enterprises, and 39 people would recommend implant systems outside the centralized volume-based procurement catalog to patients; 140 people were unable to accurately grasp all the contents of the " Nine Guidelines on Integrity for Staff of Medical Institution" ; Only 202 people believed that compliance contact with distribution companies could only be based on listening to their introduction to the implant system. 23 questionnaires were effectively collected from dental implant consumables distribution companies. Among them, 22 companies would reduce their expenses in maintaining relationships with clinical doctors after the implementation of the centralized procurement policy, and 14 companies would reduce their sales position expenses. All distribution companies believed that the phenomenon of medical institution staff receiving red envelopes and kickbacks would decrease or disappear after the implementation of the centralized volume-based procurement policy.Conclusions:The implementation of the policy of centralized volume-based procurement of dental implant consumables is beneficial for reducing the existing corruption risks in public hospitals, but if regulatory oversight is inadequate, new corruption risks will arise in the early stages of policy implementation. Public hospitals should improve the supporting system for centralized volume-based procurement of dental implant consumables, standardize the procurement process of dental implant consumables outside the centralized volume-based procurement catalog, strengthen supervision and inspection of centralized procurement, and further strengthen corruption risk prevention and control by implementing anti-corruption education.

The hypoxic microenvironment and inflammatory state of residual tumors caused by insufficient radio-frequency ablation(iRFA)are major reasons for rapid tumor progression and pose challenges for immu-notherapy.We retrospectively analyzed the clinical data of patients with hepatocellular carcinoma(HCC)treated with RFA and observed that iRFA was associated with poor survival outcomes and progression-free survival.Using an orthotopic HCC mouse model and a colorectal liver metastasis model,we observed that treatment with melatonin after iRFA reduced tumor growth and metastasis and achieved the best out-comes when combined with anti-programmed death-ligand 1(anti-PD-L1)therapy.In mechanism,melatonin inhibited the expression of epithelial-mesenchymal transitions,hypoxia-inducible factor(HIF)-1 α,and PD-L1 in tumor cells after iRFA.Flow cytometry revealed that melatonin reduced the proportion of myeloid-derived suppressor cells and increased the proportion of CD8+T cells.Transcriptomic analysis revealed an upregulation of immune-activated function-related genes in residual tumors.These findings demonstrated that melatonin can reverse hypoxia and iRFA-induced inflammation,thereby overcoming the immunosuppressive tumor microenvironment(TME)and enhancing the efficacy of immunotherapy.
