OBJECTIVE: To evaluate the efficacy and safety of DCAG (decitabine, cytarabine, anthracyclines, and granulocyte colony-stimulating factor) regimen in the treatment of patients with relapsed/refractory (R/R) acute myeloid leukemia (AML). METHODS: The clinical data of 64 R/R AML patients received treatment at Chinese PLA General Hospital from January 1st, 2012 to December 31st, 2022 were retrospectively analyzed. Primary endpoints included efficacy measured by overall response rate (ORR) and safety. Secondary endpoints included overall survival (OS), event-free survival (EFS) and duration of response (DOR). The patients were followed from enrollment until death, or the end of last follow-up (June 1st, 2023), whichever occurred first. RESULTS: Sixty-four patients who failed prior therapy were enrolled and completed 1 cycle, and 26 and 5 patients completed 2 and 3 cycles, respectively. Objective response rate was 67.2% ［39: complete remission (CR)/CR with incomplete hematologic recovery (CRi), 4: partial remission (PR)］. With a median follow-up of 62.0 months (1.0-120.9), the median overall survival (OS) was 23.3 and event-free survival was 10.6 months. The median OS was 51.7 months (3.4-100.0) in responders (CR/CRi/PR) while it was 8.4 months (6.1-10.7) in nonresponders ( P <0.001). Grade 3-4 hematologic toxicities were observed in all patients. Four patients died from rapid disease progression within 8 weeks after chemotherapy. CONCLUSION The DCAG regimen represents a feasible and effective treatment for R/R AML.

Tinnitus is a clinically refractory disease with a high incidence.LAI's Tongyuan acupuncture method believes that tinnitus is nothing more than the two ends of deficiency and excess.The deficiency is closely related to original spirit,and the excess is related to the pathological factors such as externally-contracted six pathogenic factors,phlegm-damp and blood stasis,and qi stagnation and yang constraint.The Tongyuan acupuncture method is based on original spirit,takes the two vessels of conception vessel(CV)and governor vessel(GV)as the general outline,takes the regulation of yin and yang as the main method,pays attention to the combination of local and overall,and emphasizes the application of tonification and purgation,and has the clinical effect of reinforcing healthy qi and dispelling pathogen,cultivating the vital essence.In clinical application,the method of'unblocking governor vessel and nourishing spirit'is used to play the role of heart and brain nourishing spirit and warming and supporting yang qi.The method of'conducting qi back to its source'has the effect of cultivating the vital essence and regulating qi movement.The treatments should be cooperated according to the syndromes,so that the pathogens can be expelled and healthy qi can be settled.Qi and blood have origins of generation and transformation and normally nourishing in the ear,so as to effectively alleviate the patient's tinnitus symptoms.This paper summarizes and analyzes Professor LAI Xin-Sheng's Experience in the diagnosis and treatment of tinnitus by Tongyuan acupuncture method,and provides a new acupuncture treatment plan for clinical application.

The traditional Chinese medicine （TCM） in pediatric care has a long history，proven efficacy，and distinctive characteristics.The China Association of Chinese Medicine has organized a series of youth salons to discuss the clinical advantages of treating diseases.Experts at this seminar proposed that the superior disease categories in pediatric TCM are significant for showcasing the unique strengths and advantages of TCM in the treatment of pediatric diseases，enhancing diagnostic and treatment levels，inheriting TCM knowledge，promoting the integration of TCM and Western medicine，and meeting patients' needs.The strengths of pediatric TCM are summed up as "having what others do not，excelling at what others have，being special in what others excel at，and ensuring safety in what others specialize in." The scope of superiority in pediatric TCM covers multiple systems，including respiratory，digestive，endocrine，psychological，and dermatological systems.This article summarized the advantages of TCM in treating 13 diseases discussed in the salon，such as upper respiratory tract infections，coughs，pneumonia，allergic rhinitis，bronchial asthma，atopic dermatitis，functional dyspepsia，functional constipation，enuresis，marginal short stature，simple obesity，attention deficit hyperactivity disorder，and tic disorders.The overall advantages were reflected in three aspects：First，the holistic concept and treatment based on syndrome differentiation in TCM highlight the advantage of treating the root causes of diseases，making the treatment methodical and precise.Second，most traditional Chinese herbs are natural and have strong safety profiles.Third，TCM treatment methods are abundant，especially the external treatment methods，which are widely used in pediatrics，highly accepted by parents，and have definite efficacy，as well as good safety and compliance.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective: To understand the current status of diagnosis and treatment of chronic lymphocytic leukemia (CLL) /small lymphocytic lymphoma (SLL) among hematologists, oncologists, and lymphoma physicians from hospitals of different levels in China. Methods: This multicenter questionnaire survey was conducted from March 2021 to July 2021 and included 1,000 eligible physicians. A combination of face-to-face interviews and online questionnaire surveys was used. A standardized questionnaire regarding the composition of patients treated for CLL/SLL, disease diagnosis and prognosis evaluation, concomitant diseases, organ function evaluation, treatment selection, and Bruton tyrosine kinase (BTK) inhibitor was used. Results: ①The interviewed physicians stated that the proportion of male patients treated for CLL/SLL is higher than that of females, and the age is mainly concentrated in 61-70 years old. ②Most of the interviewed physicians conducted tests, such as bone marrow biopsies and immunohistochemistry, for patient diagnosis, in addition to the blood test. ③Only 13.7% of the interviewed physicians fully grasped the initial treatment indications recommended by the existing guidelines. ④In terms of cognition of high-risk prognostic factors, physicians' knowledge of unmutated immunoglobulin heavy-chain variable and 11q- is far inferior to that of TP53 mutation and complex karyotype, which are two high-risk prognostic factors, and only 17.1% of the interviewed physicians fully mastered CLL International Prognostic Index scoring system. ⑤Among the first-line treatment strategy, BTK inhibitors are used for different types of patients, and physicians have formed a certain understanding that BTK inhibitors should be preferentially used in patients with high-risk factors and elderly patients, but the actual use of BTK inhibitors in different types of patients is not high (31.6%-46.0%). ⑥BTK inhibitors at a reduced dose in actual clinical treatment were used by 69.0% of the physicians, and 66.8% of the physicians had interrupted the BTK inhibitor for >12 days in actual clinical treatment. The use of BTK inhibitors is reduced or interrupted mainly because of adverse reactions, such as atrial fibrillation, severe bone marrow suppression, hemorrhage, and pulmonary infection, as well as patients' payment capacity and effective disease progression control. ⑦Some differences were found in the perceptions and behaviors of hematologists and oncologists regarding the prognostic assessment of CLL/SLL, the choice of treatment options, the clinical use of BTK inhibitors, etc. Conclusion: At present, a gap remains between the diagnosis and treatment of CLL/SLL among Chinese physicians compared with the recommendations in the guidelines regarding the diagnostic criteria, treatment indications, prognosis assessment, accompanying disease assessment, treatment strategy selection, and rational BTK inhibitor use, especially the proportion of dose reduction or BTK inhibitor discontinuation due to high adverse events.

OBJECTIVES: To select four algorithms with relatively balanced complexity and accuracy among deep learning image classification algorithms for automatic diatom recognition, and to explore the most suitable classification algorithm for diatom recognition to provide data reference for automatic diatom testing research in forensic medicine. METHODS: The "diatom" and "background" small sample size data set (20 000 images) of digestive fluid smear of corpse lung tissue in water were built to train, validate and test four convolutional neural network (CNN) models, including VGG16, ResNet50, InceptionV3 and Inception-ResNet-V2. The receiver operating characteristic curve (ROC) of subjects and confusion matrixes were drawn, recall rate, precision rate, specificity, accuracy rate and F1 score were calculated, and the performance of each model was systematically evaluated. RESULTS: The InceptionV3 model achieved much better results than the other three models with a balanced recall rate of 89.80%, a precision rate of 92.58%. The VGG16 and Inception-ResNet-V2 had similar diatom recognition performance. Although the performance of diatom recall and precision detection could not be balanced, the recognition ability was acceptable. ResNet50 had the lowest diatom recognition performance, with a recall rate of 55.35%. In terms of feature extraction, the four models all extracted the features of diatom and background and mainly focused on diatom region as the main identification basis. CONCLUSIONS Including the Inception-dependent model, which has stronger directivity and targeting in feature extraction of diatom. The InceptionV3 achieved the best performance on diatom identification and feature extraction compared to the other three models. The InceptionV3 is more suitable for daily forensic diatom examination.
