RESUMEN
Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of national bloodstream infection Bacterial Resistant Investigation Collaborative System(BRICS)were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute(CLSI). WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:During the study period,9 035 strains of Gram-negative bacteria were collected from 51 hospitals,of which 7 895(87.4%)were Enterobacteriaceae and 1 140(12.6%)were non-fermenting bacteria. The top 5 bacterial species were Escherichia coli( n=4 510,49.9%), Klebsiella pneumoniae( n=2 340,25.9%), Pseudomonas aeruginosa( n=534,5.9%), Acinetobacter baumannii complex( n=405,4.5%)and Enterobacter cloacae( n=327,3.6%). The ESBLs-producing rates in Escherichia coli, Klebsiella pneumoniae and Proteus spp. were 47.1%(2 095/4 452),21.0%(427/2 033)and 41.1%(58/141),respectively. The prevalence of carbapenem-resistant Escherichia coli(CREC)and carbapenem-resistant Klebsiella pneumoniae(CRKP)were 1.3%(58/4 510)and 13.1%(307/2 340);62.1%(36/58)and 9.8%(30/307)of CREC and CRKP were resistant to ceftazidime/avibactam combination,respectively. The prevalence of carbapenem-resistant Acinetobacter baumannii(CRAB)complex was 59.5%(241/405),while less than 5% of Acinetobacter baumannii complex was resistant to tigecycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa(CRPA)was 18.4%(98/534). There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of main Gram-negative bacteria resistance among different regions,with statistically significant differences in the prevalence of CRKP and CRPA( χ2=20.489 and 20.252, P<0.001). The prevalence of CREC,CRKP,CRPA,CRAB,ESBLs-producing Escherichia coli and Klebsiella pneumoniae were higher in provinicial hospitals than those in municipal hospitals( χ2=11.953,81.183,10.404,5.915,12.415 and 6.459, P<0.01 or <0.05),while the prevalence of CRPA was higher in economically developed regions(per capita GDP ≥ 92 059 Yuan)than that in economically less-developed regions(per capita GDP <92 059 Yuan)( χ2=6.240, P=0.012). Conclusions:The proportion of Gram-negative bacteria in bloodstream infections shows an increasing trend,and Escherichia coli is ranked in the top,while the trend of CRKP decreases continuously with time. Decreasing trends are noted in ESBLs-producing Escherichia coli and Klebsiella pneumoniae. Low prevalence of carbapenem resistance in Escherichia coli and high prevalence in CRAB complex have been observed. The composition ratio and antibacterial spectrum of bloodstream infections in different regions of China are slightly different,and the proportion of main drug resistant bacteria in provincial hospitals is higher than those in municipal hospitals.
RESUMEN
Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical bacterial isolates from bloodstream infections in China in 2021.Methods:The clinical bacterial strains isolated from blood culture from member hospitals of Blood Bacterial Resistant Investigation Collaborative System (BRICS) were collected during January 2021 to December 2021. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical Laboratory Standards Institute (CLSI). WHONET 5.6 was used to analyze data.Results:During the study period, 11 013 bacterial strains were collected from 51 hospitals, of which 2 782 (25.3%) were Gram-positive bacteria and 8 231 (74.7%) were Gram-negative bacteria. The top 10 bacterial species were Escherichia coli (37.6%), Klebsiella pneumoniae (18.9%), Staphylococcus aureus (9.8%), coagulase-negative Staphylococci (6.3%), Pseudomonas aeruginosa (3.6%), Enterococcus faecium (3.6%), Acinetobacter baumannii (2.8%), Enterococcus faecalis (2.7%), Enterobacter cloacae (2.5%) and Klebsiella spp (2.1%). The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative Staphylococcus aureus were 25.3% and 76.8%, respectively. No glycopeptide- and daptomycin-resistant Staphylococci was detected; more than 95.0% of Staphylococcus aureus were sensitive to ceftobiprole. No vancomycin-resistant Enterococci strains were detected. The rates of extended spectrum B-lactamase (ESBL)-producing isolated in Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis were 49.6%, 25.5% and 39.0%, respectively. The prevalence rates of carbapenem-resistance in Escherichia coli and Klebsiella pneumoniae were 2.2% and 15.8%, respectively; 7.9% of carbapenem-resistant Klebsiella pneumoniae was resistant to ceftazidime/avibactam combination. Ceftobiprole demonstrated excellent activity against non-ESBL-producing Escherichia coli and Klebsiella pneumoniae. Aztreonam/avibactam was highly active against carbapenem-resistant Escherichia coli and Klebsiella pneumoniae. The prevalence rate of carbapenem-resistance in Acinetobacter baumannii was 60.0%, while polymyxin and tigecycline showed good activity against Acinetobacter baumannii (5.5% and 4.5%). The prevalence of carbapenem-resistance in Pseudomonas aeruginosa was 18.9%. Conclusions:The BRICS surveillance results in 2021 shows that the main pathogens of blood stream infection in China are gram-negative bacteria, in which Escherichia coli is the most common. The MRSA incidence shows a further decreasing trend in China and the overall prevalence of vancomycin-resistant Enterococci is low. The prevalence of Carbapenem-resistant Klebsiella pneumoniae is still on a high level, but the trend is downwards.
RESUMEN
Objective:To explore the clinical application value of preoperative colonoscopic marking by Nd-Fe-B magnet ring to assist laparoscopy.Methods:A total of 51 patients with colorectal tumor who underwent radical laparoscopy from January 2020 to October 2021 at the Department of Gastrointestinal Surgery, Guizhou Provincial People's Hospital were recruited. The patients were marked by Nd-Fe-B magnet ring under endoscopy one day before the operation, another magnet ring was sent into the abdominal cavity during the radical laparoscopy through cannula. The two magnet rings were attracted and clung to each other to orient the lesions. The basic information of patients, location of preoperative marks under endoscopy and laparoscopy conditions were recorded.Results:All 51 Nd-Fe-B magnet rings were successfully located to the position of colorectal tumor and fixed. According to the location of the lesions, there were 15 cases of transverse colon, 12 cases of descending colon, 19 cases of sigmoid colon, and 5 cases of upper rectal segment. According to the lesion type, there were 21 cases of colon cancer, 25 cases of polyp carcinomatosis, and 5 cases of laterally spreading tumors with partial carcinomatosis. There were 5 cases with positive margins after endoscopic mucosal resection and 1 case with positive margin after endoscopic submucosal dissection. All lesions were accurately located during the operation. The marking time was 4.1±1.2 min (3-6 min) before the operation and the localization time was 1.5±1.1 min (0.9-5.3 min) during the operation. All magnet rings were removed from the body by laparoscope. The mean distances between the tumor and the cutting edge of the proximal and distal intestinal segments were 5.5 cm and 6.3 cm, respectively. No complications such as colon mucosal injury, bleeding, intestinal perforation or local inflammatory reactions occurred.Conclusion:Nd-Fe-B magnet ring tracer technique for laparoscopic orientation is simple, fast, accurate and safe with no need for additional equipment or apparatus, which is worthy of clinical application.
RESUMEN
BACKGROUND@#There is limited data to comprehensively evaluate the epidemiological characteristics of multiple myeloma (MM) in China; therefore, this study determined the characteristics of the disease burden of MM at national and provincial levels in China.@*METHODS@#The burden of MM, including incidence, mortality, prevalence, and disability-adjusted life years (DALYs), with a 95% uncertainty interval (UI), was determined in China following the general analytical strategy used in the Global Burden of Disease, Injuries, and Risk Factors Study 2019. The trends in the burden of MM from 1990 to 2019 were also evaluated.@*RESULTS@#There were an estimated 347.45 thousand DALYs with an age-standardized DALY rate of 17.05 (95% UI, 12.31-20.77) per 100,000 in 2019. The estimated number of incident case and deaths of MM were 18,793 and 13,421, with age-standardized incidence and mortality rates of 0.93 (95% UI, 0.67-1.15) and 0.67 (95% UI, 0.50-0.82) per 100,000, respectively. The age-specific DALY rates per 100,000 increased to more than 10.00 in the 40 to 44 years age group reaching a peak (93.82) in the 70 to 74 years age group. Males had a higher burden than females, with approximately 1.5- to 2.0-fold sex difference in age-specific DALY rates in all age groups. From 1990 to 2019, the DALYs of MM increased 134%, from 148,479 in 1990 to 347,453 in 2019.@*CONCLUSION@#The burden of MM has doubled over the last three decades, which highlights the need to establish effective disease prevention and control strategies at both the national and provincial levels.

RESUMEN
Objective:To explore the role of 18F-fluorodeoxyglucose (FDG) PET/CT in early detection of therapy-associated cardiotoxicity (TACT) in lymphoma patients and to analyze the diagnostic efficacy of different evaluation criteria. Methods:Consecutive patients between November 2009 to October 2018 in Peking University Cancer Hospital were retrospectively enrolled. All patients underwent standard chemotherapy. Myocardial uptake of 18F-FDG pre- and post-treatment were analyzed by visual interpretation and semi-quantitative (maximum standardized uptake value, SUV max) methods. The value of pre-treatment SUV max-heart -post-treatment SUV max-heart (ΔSUV max), %ΔSUV max, and post-treatment SUV max-heart/SUV max-mediastinum, SUV max-heart/SUV max-liver and SUV max-heart/SUV max-background(left gluteal muscle) ratios were calculated. Receiver operating characteristic (ROC) curve analysis was performed to determine optimal cut-off values of those PET/CT imaging criteria for evaluating early TACT of lymphoma, taking electrocardiogram (ECG) positive as the end point. Independent-sample t test and χ2 test were performed. Results:A total of 274 patients (median age was 36-year old), with the male-to-female ratio of 1.85∶1, were included, and 78.1%(214/274) of them had non-Hodgkin′s lymphoma (NHL). After treatment, 55.1%(151/274)of the patients had high myocardial uptake of 18F-FDG (compared with liver uptake), 20.4%(56/274) of them had moderate myocardial uptake (between liver uptake and blood-pool uptake), and 24.5%(67/274) were with equal uptake (less than blood-pool uptake). There were significant differences in myocardial uptake between ECG-positive group ( n=71) and ECG-negative group ( n=203) ( SUV max: 7.77±4.06 vs 5.91±3.04; t=4.045, P<0.01). ROC curves showed that optimal thresholds of post-treatment SUV max-heart, Δ SUV max-heart, %ΔSUV max-heart, and post-treatment SUV max-heart/SUV max-mediastinum, SUV max-heart/SUV max-liver and SUV max-heart/SUV max-background ratios were 9.4, 4.8, 1.4, 5.0, 2.3, 7.0 respectively. The corresponding areas under the curves (AUC) were 0.653, 0.637, 0.612, 0.655, 0.649 and 0.650, respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of post-treatment SUV max-heart/SUV max-background ratio were 40.85%(29/71), 82.76%(168/203), 45.31%(29/64), 80.00%(168/210) and 71.90%(197/274). Conclusion:18F-FDG PET/CT can early detect TACT in patients with lymphoma, and if using 7.0 as the threshold of post-treatment SUV max-heart/SUV max- background ratio, the specificity and negative predictive value of 18F-FDG PET/CT for early prediction of TACT are up to 80%.
RESUMEN
Chimeric antigen receptor T (CAR-T) cell has achieved excellent efficacy in hematological tumors, especially for lymphoma. Many products have been approved to market all over the world, and 2 products targeting CD19 have been approved to treat relapsed and refractory large B-cell lymphoma in China. The current experiences of using CAR-T cells come from previous clinical studies. How to use CAR-T cells in a standardized and rationalized way is still a challenge faced by our clinicians. Based on the CAR-T cell treatment experiences from Peking University Cancer Hospital and the latest research progresses in CAR-T in China and abroad, this article will elaborate on patient screening, peripheral blood mononuclear cell collection, bridging treatment, lymphocyte depletion chemotherapy, CAR-T cell infusion, the monitoring and treatment of adverse events after infusion, and long-term follow-up after infusion, in order to guide clinicians to better use CAR-T cell and to bring maximum benefits to patients.

RESUMEN
Objective@#To analyze the characteristics of the second primary tumor affecting the survival of patients with lymphoma, and to explore the risk factors of death from the second primary tumor.@*Methods@#The medical records and related death information of 1 173 lymphoma patients who had already died with known causes were collected. The basic causes of death and the characteristics of patients who died of the second primary tumor were analyzed. Cox regression model was used to analyze the risk factors of lymphoma patients who died of the second primary tumor.@*Results@#Among the 1 173 patients who had died, 94 (8.0%) died of the second primary tumor, 935 (79.7%) died of the primary lymphoma and 144 (12.3%) died of other diseases. The second primary tumor accounted for 17.5% (38/217) of all causes of death in patients with the survival period of more than 5 years, and the second primary tumor accounted for 28.3% (17/60) of all causes of death in patients with the survival period of more than 10 years. Among 94 cases who died of second primary tumors, 31 died of lung cancer, 15 died of gastric cancer, 13 died of liver cancer, 9 died of pancreatic cancer, 6 died of colorectal cancer, 6 died of second primary lymphoma and 14 died of other types of tumors. Univariate Cox regression analysis showed that age, first-line treatment effect, and chest or mediastinal radiotherapy were associated with the death from second primary tumors for lymphoma patients (all P<0.05). Multivariate Cox regression analysis showed that the effect of first-line treatment (P=0.030) and the chest or mediastinal radiotherapy (P=0.039) were independent factors for the death of lymphoma patients from the second primary tumor.@*Conclusions@#The second primary tumor is an important factor affecting the survival of lymphoma patients, and the risk of death from second primary tumors increases significantly over time. The effect of first-line treatment and radiotherapy in the chest or mediastinum are independent factors for the death of lymphoma patients from the second primary tumor.
RESUMEN
To evaluate the impact of admission diagnosis on seizure outcome in patients with autoimmune epilepsy (AE). Methods: We conducted a retrospective study on 40 AE patients at Department of Neurology, Xiangya Hospital, Central South University from Jan. 1st, 2017 to Nov. 21st, 2018. According to their admission diagnosis, these patients were further assigned into 2 groups: An AE diagnosed group and an AE undiagnosed group. Demographic data, clinical characteristics, cerebrospinal fluid (CSF), electroencephalogram, and brain imaging were compared between the 2 groups. Favorable seizure outcome was defined as >50% reduction of seizure frequency at the first follow-up. The impact of admission diagnosis on seizure outcome of AE patients was analyzed. Results: The ages of 40 AE patients were (33.23±16.41) years, comprising 19 males and 21 females. No significant difference was found between the AE diagnosed group and the AE undiagnosed group in gender, age, central nervous system-specific Ab profile, CSF, and brain imaging. Duration of symptom onset to Ab detection was significantly longer in the AE undiagnosed group than that in the AE diagnosed group (P<0.01). Duration of symptom onset to immunotherapy was also significantly longer in the AE undiagnosed group than that in the AE diagnosed group (P<0.001). There were more patients with favorable seizure outcome in the AE diagnosed group than the AE undiagnosed group (P<0.05). Conclusion: Admission diagnosis for patients with AE is associated with seizure outcome after immunotherapy. For adult-onset epilepsy or epilepsy with unknown etiology, the diagnosis of AE should be considered. Early diagnosis of AE and prompt initiation of immunosuppressive treatment are crucial to increase the likelihood of achieving favorable seizure outcome.

RESUMEN
Objective: To analyze the effect of abnormal T cell subsets on the prognosis of patients with lymphoma after autologous hematopoietic stem cell transplantation (AHSCT). Methods: The clinical data of 55 patients with lymphoma who receivedAHSCT from January 2016 to December 2017 were collected. The correlation of abnormal T cell subsets with the outcome of AHSCT was analyzed retrospectively, and the effect of abnormal T cell subsets on the prognosis of patients after AHSCT was evaluated. Results: The age of lymphoma patients was correlated with the increased percentages of CD3+ cells and CD3+CD16+CD56+ cells and the decreased percentage of CD19+ cells (all P 0.05). Relapsed/refractory lymphomas and the decreased percentage of CD3-CD16+CD56+ cells were identified as independent risk factors for the progression/relapse of tumor after AHSCT (both P < 0.05). Based on the stratification by these two factors, the incidence of progression/relapse after AHSCT was 10.0%, 32.3% or 100.0% in the patients without risk factor, with 1 or 2 risk factors, respectively (P = 0.001). Conclusion: The abnormal T cell subsets may be a poor prognostic factor for the patients with lymphoma received AHSCT.
RESUMEN
The prognosis of lymphoma patients is relatively good, and most patients may survive for a long time after standard treatment. Long-term follow-up of lymphoma survivors may reveal some late complications related to the treatment. Analysis of the causes of death is helpful in further improving the prognosis of lymphoma patients. The purpose of this article is to review the causes of death in patients with lymphoma during long-term follow-up to generate new ideas for follow-up and treatment of lymphoma patients.
RESUMEN
Objective: To understand the causes of death and long-term prognosis of lymphoma patients. Methods: Data from 6 200 patients with lymphoma admitted to the Department of Lymphoma, Peking University Cancer Hospital, from January 1995 to Decem-ber 2017, were collected. Those who had died and whose causes of death were known were selected. Clinical records and information on death were collected. Results: A total of 1,173 patients were selected, 742 of whom were male (63.3% ), and 431 were female (36.7%). The median age was 56 (8-92) years. There were 77 cases (6.6%) of Hodgkin's lymphoma, 1,095 cases (93.4%) of non-Hodg-kin's lymphoma, and 1 case of unclear pathological classification. Overall population survival was 0-253 months, with a median surviv-al rate of 20 months. The direct causes of death included lymphoma in 688 (58.7%), various infectious diseases in 119 (10.1%), cardio-vascular diseases in 96 (8.2%), secondary primary tumors in 68 (5.8%), and other diseases in 202 cases (17.2%). The underlying causes of death included lymphoma in 936 (79.8%), secondary primary tumors in 94 (8.0%), cardiovascular diseases in 75 (6.4%), respiratory diseases in 32 (2.7%) and other diseases in 36 cases (3.1%). The underlying causes of death in cases wherein survival time exceeded 5 years included lymphoma in 129 (59.4%), secondary primary tumors in 38 (17.5%), cardiovascular diseases in 35 (16.1%), and other dis-eases in 15 cases (6.9%). The underlying causes of death in cases wherein survival time exceeded 10 years included lymphoma in 28 (46.7%), secondary primary tumors in 17 (28.3%), cardiovascular diseases in 7 (11.7%), and other diseases in 8 cases (13.3%). Conclu-sions: Primary tumors remain the main cause of death in patients with lymphoma. After primary tumors, secondary primary tumors and cardiovascular diseases are the most common causes of death, and with the prolongation of survival, the risk of death caused by these factors increases significantly.

OBJECTIVE:To study the relationship of GSTP 1(rs1695)(simply as GSTP 1)gene polymorphism with the hematological toxicity in autologous hematopoietic stem cell transplantation(AHSCT)patients who used CBV regimen (cyclophosphamide,carmustine,etoposide). METHODS:A total of 83 AHSCT patients receiving CBV regimen were retrospective analyzed in our hospital during Apr. 2015-Jun. 2017. The gene polymorphism of GSTP 1 A313G was detected by fluorescence staining in situ hybridization. The hematological toxicity and the incidence of agranulocytosis fever,the implantation time of leukocyte,neutrophils and platelet were analyzed statistically. The relationship of GSTP 1 with above indexes were analyzed. RESULTS:Among 83 patients,gene variation was observed in one gene loci at least of 28 patients(33.73%).The gene frequency of A allele was 81.3%,while that of G allele was 18.7%. The reduce time of Ⅳ grade leukopenia,Ⅳ grade neutropenia and Ⅳgrade thrombocytopenia in GSTP 1 AA genotype patients were(8.91 ± 1.25),(9.02 ± 1.19),(11.56 ± 1.58)d after chemotherapy;those of patients with GSTP 1 313 allele G(AG/GG genotype) were(8.61 ± 1.17),(8.68 ± 1.19),(11.44 ± 1.34)d after chemotherapy. The implantation time of leukocyte,neutrophils and platelet in patients with GSTP 1 AA genotype were(11.98±1.99),(10.44±1.35),(15.55±2.18)d after autologus peripheral blood stem cell reinfusion;those of patients with GSTP1 313 allele G(AG/GG genotype)were(12.41±2.44),(10.36±1.62),(16.29±3.15)d after autologus peripheral blood stem cell reinfusion. The case number of grade Ⅲ-Ⅳ anemia were 24 and 11,accounting for 43.64% and 39.29% of corresponding genotype patients. The case number of agranulocytosis fever in patients with GSTP 1 AA genotype or GSTP 1 313 allele G(AG/GG genotype)were 21 and 11 during transplantation,accounting for 38.18% and 39.29% of corresponding genotype patients, respectively,without statistical significantly(P>0.05). CONCLUSIONS:There is no relationship between GSTP 1 gene polymorphism and hematological toxicity of AHSCT patients receiving CBV regimen.
RESUMEN
Objective:To investigate the types of non-tumor diseases in patients with cancer, and to explore the effects of those dis-eases on the diagnosis and treatment of cancer patients. Methods:We collected the medical records of cancer patients from January 2013 to December 2017 in Peking University Cancer Hospital, and screened for non-tumor diseases. The clinical records of the patients in this group were analyzed retrospectively, and the effects of those diseases on the diagnosis and treatment of tumors were dis-cussed. Results:Of the 1,323 cases of inter-hospital consultation, 1,153 cases of non-tumor disease (87.2%) were selected. There were 773 men (67.0%) and 380 women (33.0%) included. The median age was 62 (14-90) years. The primary tumor types included lung can-cer, gastric cancer, lymphoma, colorectal cancer, esophageal cancer, breast cancer, malignant melanoma, liver cancer, cholangiocarci-noma/gallbladder cancer, pancreatic cancer, and other tumors. Non-neoplastic diseases included cardiovascular disease in 356 cases (30.9%), respiratory system disease (17.0%) in 196 cases, digestive system disease in 107 cases (9.3%), skin and venereal diseases in 81 cases (7.0%), nervous system lesions (6.4%) in 74 cases, urinary system disease in 72 cases (6.2%), blood disease in 70 cases (6.1%), en-docrine and metabolic diseases in 47 cases (4.1%), autoimmune disease in 23 cases (2.0%), and other diseases (11.0%) in 127 cases. Impact on tumor diagnosis and treatment was as follows:direct, 771 cases (66.9%);no influence, 313 cases (27.1%);and uncertain, 69 cases (6.0%). Conclusions:Cardiovascular disease is a major non-tumor disease associated with cancer. Non-neoplastic diseases are important factors affecting the diagnosis and treatment plans of cancer.
