This article summarized the important considerations during drafting and provided reasonable suggestions, which can be used as a reference for standardization professionals.

Laparoscopic subtotal cholecystectomy (LSC) has been a safe and viable alternative to conversion to laparotomy in cases of severe cholecystitis. The objective of this study is to determine the utility of intraoperative choledochoscopy in LSC for the exploration of the gallbladder, cyst duct, and subsequent stone clearance of the cystic duct in cases of severe cholecystitis. A total of 72 patients diagnosed with severe cholecystitis received choledochoscopy-assisted laparoscopic subtotal cholecystectomy (CALSC). A choledochoscopy was performed to explore the gallbladder cavity and/or cystic duct, and to extract stones using a range of techniques. The clinical records, including the operative records and outcomes, were subjected to analysis. No LSC was converted to open surgery, and no bile duct or vascular injuries were sustained. All stones within the cystic duct were removed by a combination of techniques, including high-frequency needle knife electrotomy, basket, and electrohydraulic lithotripsy. A follow-up examination revealed the absence of residual bile duct stones, with the exception of one common bile duct stone, which was extracted via endoscopic retrograde cholangiopancreatography. In certain special cases, CALSC may prove to be an efficacious treatment for the management of severe cholecystitis. This technique allows for optimal comprehension of the situation within the gallbladder cavity and cystic duct, facilitating the removal of stones from the cystic duct and reducing the residue of the non-functional gallbladder remnant.

Viral infection has always been a significant challenge to human health. Transplant recipients, including those who have undergone solid organ transplantation and allogeneic hematopoietic stem cell transplantation, are at high risk of viral infection due to their weak immune function under immunosuppressive therapy. Unlike the general population, transplant recipients are prone to pneumonia and even severe pneumonia after respiratory viral infection, which requires close attention from clinicians. Therefore, this article reviews the clinical characteristics and special management of viral infection in this population, focusing on the epidemiological features of common respiratory viral infection in transplant recipients, early diagnosis and intervention after infection, severe warning signs and drug treatment strategies, for the reference of clinical colleagues.

Objective:To investigate the effect of flow cytometric minimal residual disease(MRD)detection at different time points during AML chemotherapy on prognosis.Methods:130 adult primary AML patients diagnosed and standardized with chemotherapy from March 2018 to March 2022 were retrospectively analyzed,MRD was detected by flow cytometry,Kaplan-Meier curves was used for survival analysis and log-rank test was used for variance analysis,and univariate and multifactor influencing patient survival with COX proportional risk regression model analysis.Cumulative incidence rate(CIR)analysis with competing risk model and variance analysis using Fine-Gray.Results:There were 81 CR1,26 CR2,14 PR,and 9 NR patients in 130 patients.OS of the CR1 group was higher than that in the CR2,PR,and NR groups.OS of the CR2 group was higher than that in the PR group,but there was no statistically difference compared to the NR group.There was no statistically difference in OS between the PR and NR groups.107 patients in CR1 and CR2 were grouped according to MRD detected by flow cytometry,and after the first induction chemotherapy,for patients in the MRD-and MRD+groups,the 4-year expected RFS rates were 65.3％and 27.9％respectively,the 4-year expected OS rates were 58.7％and41.4％respectively,and the 4-year expected CIR were 34.7％and 69.7％respectively,with statistically significant differences between 2 groups(x2=6.639,P=0.010;x2=6.131,P=0.013 and x2=6.637,P=0.010).After the second chemotherapy,for patients in the MRD-and MRD+groups,the 4-year expected RFS rates were 50.8％and 37.9％respectively,the 4-year expected OS rates were 49.2％and 44.5％respectively,and the 4-year expected CIR were 49.2％and 59.5％respectively,with no statistically significant differences between 2 groups(x2=1.475,P=0.225;x2=2.432,P=0.119 and x2=1.416,P=0.234).During consolidation therapy,for patients in the MRD-and MRD+groups,the 4-year expected RFS rates were 51.9％and 29.6％respectively,the 4-year expected OS rates were 67.5％and 24.6％respectively,and the 4-year expected CIR were 48.1％and 70.4％respectively,with statistically significant differences between 2 groups(x2=20.982,P＜0.001;x2=17.794,P＜0.001 and x2=19.879,P＜0.001).For patients with MRD-at all three time points and positive at either time point,the 4-year expected RFS rates were 69.9％and 33.3％respectively,the 4-year expected OS rates were 59.1％and 44.7％respectively,and the 4-year expected CIR were 30.1％and 65.1％respectively,with statistically significant differences between 2 groups(x2=7.367,P=0.007;x2=6.042,P=0.014 and x2=7.662,P=0.006).Univariate analysis showed that karyotype at high risk of chromosome was an unfavorable factor affecting patients'RFS and OS,while 2 cycles of induction chemotherapy achieved CR,MRD-after the first induction chemotherapy and MRD-after the second induction chemotherapy was a protective factor affecting patients'RFS and OS.MRD-during consolidation therapy and MRD-at all three time points were all protective factors affecting patients'RFS,OS and CIR.Multivariate analysis showed that induction chemotherapy for 2 cycles achieved CR was a protective factor affecting patients'RFS and CIR,and MRD-during consolidation therapy was a protective factor affecting patients'RFS,OS and CIR.Conclusion:Early achievement of CR and MRD-in adult AML patients,especially MRD-during consolidation therapy,is a marker of good prognosis,and flow cytometry is the most commonly used method for MRD detection in AML patients.

Long-term use of immunosuppressants result in an immunocompromised state, repeated hospitalizations and dosing of broad-spectrum antibiotics. Presence of transplant-associated diabetes and cadaveric donations are contributing factors to a higher risk of invasive fungal disease (IFD ) among solid organ transplantation (SOT) recipients. Furthermore, the epidemiology of IFD in SOT recipients has continuously evolved in recent years. Understanding the current epidemiological status of IFD in SOT recipients, becoming familiar with new diagnostic technologies for IFD and mastering the characteristics of novel antifungal medications may further improve the prognosis for recipients. This review summarized the incidence, pathogen composition, new diagnostic technologies and recently marketed novel antifungal medications for IFD in SOT recipients, aiming to offer references for clinical practices.

Objective To explore the current application of high-throughput drug sensitivity(HDS)testing in children with relapsed and refractory acute leukemia(RR-AL)and analyze the feasibility of salvage treatment plans.Methods A retrospective collection of clinical data from children with RR-AL who underwent HDS testing at the Department of Children's Hematology and Oncology of the First Affiliated Hospital of Zhengzhou University from November 2021 to October 2023 was conducted,followed by an analysis of drug sensitivity results and treatment outcomes.Results A total of 17 children with RR-AL underwent HDS testing,including 7 cases of relapsed refractory acute myeloid leukemia and 10 cases of relapsed refractory acute lymphoblastic leukemia.The detection rate of highly sensitive chemotherapy drugs/regimens was 53%(9/17),while the detection rate of moderately sensitive chemotherapy drugs/regimens was 100%(17/17).Among the 17 RR-AL patients with highly and moderately sensitive chemotherapy drugs and regimens,the MOACD regimen(mitoxantrone+vincristine+cytarabine+cyclophosphamide+dexamethasone)accounted for 100%,with the highest inhibition rate for single-agent mitoxantrone(94%,16/17),and the highest inhibition rate for targeted therapy being bortezomib(94%,16/17).Nine patients adjusted their chemotherapy based on HDS testing results,with 4 undergoing hematopoietic stem cell transplantation.Four patients achieved disease-free survival,while 5 died.Eight patients received empirical chemotherapy,with 2 undergoing hematopoietic stem cell transplantation;4 achieved disease-free survival,while 4 died.Conclusions HDS testing can identify highly sensitive drugs/regimens for children with RR-AL,improving the rate of re-remission and creating conditions for subsequent hematopoietic stem cell transplantation.

OBJECTIVE To establish the project approval evaluation system for traditional Chinese medicine （TCM） preparations in medical institutions guided by new drug conversion， to improve the success rate of approval for TCM preparations in medical institutions and lay the foundation for the later drug conversion. METHODS Research and development team used the literature research method and brainstorming method to list and organize relevant elements of project evaluation and determine the initial indicator system. Experts were consulted using the Delphi method to confirm the evaluation index. The weights were calculated based on the proportion of importance scores for each indicator and assigned specific scores to each item. The indicator system was used to evaluate 31 TCM preparations applied for filing by various departments of our hospital from April to July 2023. RESULTS After two rounds of 17 experts’ consultation， the final TCM preparation system included five primary indicators， i.e. theoretical basis， clinical research foundation， pharmaceutical foundation， prescription， and clinical value， as well as 17 secondary indicators including prescription source， traditional Chinese medicine theory， clinical positioning and so on. Human experience was considered as the item which would be rejected as one vote. Based on the above indicator system， our hospital further improved the filing and project approval process for TCM preparations in medical institutions. Among the 31 TCM preparations applied for filing by various departments from April to July 2023， 8 TCM preparations with a score ≥65 were selected for development. CONCLUSIONS The evaluation system is objective， comprehensive， and highly operable. It is suitable for the selection of TCM preparations in medical institutions before research and development.

Nocardiosis is a collective term for tissue and organ damage caused by Nocardia infection.Solid organ transplant recipients(SOTR)are at an increased risk of various pathogen infections,including Nocardia infection,due to immunosuppressive therapy which weakens their immune function.The diagnosis of nocardiosis has been challenging in the past.With the advent of molecular biology and other diagnostic methods,the diagnostic rate has significantly improved.Nocardia not only prone to cause necrotic pulmonary lesions but also invade other organs and tissues,such as intracranial infections and skin soft tissue infections,and can develop into systemic disseminated infections.For SOTR,nocardiosis is a potentially fatal disease with a fatality as high as 30%.Therefore,this article reviews the clinical characteristics of common nocardiosis in SOTR,new diagnostic technologies,and different anti-infective treatment strategies,aiming to provide a reference for the prevention and treatment of nocardiosis in clinical SOTR.
