Objective To investigate the clinical value of matrix-assisted laser desorption/ionization time of flight mass spectrometry(MALDI-TOF MS)in rapid detection of carbapenemase produced by Klebsiella pneumoniae and Pseudomonas aeruginosa.Methods A total of 60 strains of Klebsiella pneumoniae and 80 strains of Pseudomonas aeruginosa isolated from Pizhou People's Hospital affiliated to Xuzhou Medical University from January 2022 to October 2023 were collected,including 30 strains of carbapenem-resistant Klebsiella pneumoniae(CRKP),30 strains of carbapenem-sensitive Klebsiella pneumoniae(CSKP),50 strains of carbapenem-resistant Pseudo-monas aeruginosa(CRPA)and 30 strains of carbapenem-sensitive Pseudomonas aeruginosa(CSPA).Three detection methods were applied,i.e.,modified carbapenem inactivation method(mCIM),colloidal gold immunochromatography and Autof MS 1000 mass spectrometry identification system to evaluate the ability of Autof MS 1000 mass spectrometry identification system in detecting carbape-nase production of Klebsiella pneumoniae and Pseudomonas aeruginosa.Results The results of Autof MS 1000 mass spectrometry iden-tification system were consistent with those of both mCIM and colloidal gold immunochromatography.Carbapenemase was detected in 28 of the 30 CRKP strains,and it was negative in 2 CRKP strains.Carbapenamase was detected in 15 of the 50 CRPA strains and it was negative in 35 CRPA strains.Thirty strains of CSKP and 30 strains of CSPA were all Carbapenemase negative.The coincidence rate of the results of the three methods in the detection for carbapenase was 100％.Conclusion The result of Autof MS 1000 mass spectrome-try identification system has been consistent with those of mCIM and colloidal gold immunochromatography.It not only has the charac-teristics of cost-saving compare with of mCIM method,but also hold the advantages of fast speed and high accuracy of colloidal gold im-munochromatography method.Thus,Autof MS 1000 system can be used for the rapid identification of carbapenemase produced by Kleb-siella pneumoniae and Pseudomonas aeruginosa.

Rheumatoid arthritis is a chronic, systemic autoimmune disease predominantly based on joint lesions with an extremely high disability and deformity rate. Several drugs have been used for the treatment of rheumatoid arthritis, but their use is limited by suboptimal bioavailability, serious adverse effects, and nonnegligible first-pass effects. In contrast, transdermal drug delivery systems (TDDSs) can avoid these drawbacks and improve patient compliance, making them a promising option for the treatment of rheumatoid arthritis (RA). Of course, TDDSs also face unique challenges, as the physiological barrier of the skin makes drug delivery somewhat limited. To overcome this barrier and maximize drug delivery efficiency, TDDSs have evolved in terms of the principle of transdermal facilitation and transdermal facilitation technology, and different generations of TDDSs have been derived, which have significantly improved transdermal efficiency and even achieved individualized controlled drug delivery. In this review, we summarize the different generations of transdermal drug delivery systems, the corresponding transdermal strategies, and their applications in the treatment of RA.

Objective: To investigate the epidemiological characteristics of influenza outbreaks in Zhejiang Province from 2013 to 2022, so as to provide insights into influenza prevention and control. Methods: Data pertaining to influenza outbreaks reported in Zhejiang Province from 2013 to 2022 were collected from National Influenza Surveillance System in China, including time, region, cases and pathogen types of influenza outbreaks. The temporal, spatial and pathogen distribution of influenza outbreaks were analyzed using a descriptive epidemiological method. Results: A total of 577 influenza outbreaks involving 448 698 individuals were reported in Zhejiang Province from 2013 to 2022, and the overall attack rate was 5.34% (23 974 cases), with no death reported. The lowest attack rate of influenza was 0.26%, and the highest was 80.00%, with a median attack rate of 10.89% (interquartile range, 24.26%). The outbreak had the shortest duration of 1.00 day, and the longest duration of 59.00 days, with a median duration of 9.00 (interquartile range, 11.00) days. There were 387 influenza outbreaks that occurred between November and January of the following year (67.07%), and the three highest numbers of outbreaks were reported in Hangzhou City (310 outbreaks), Wenzhou City (51 outbreaks) and Jinhua City (46 outbreaks). There were 395 outbreaks reported in urban regions (68.46%), 93 in counties and townships (16.12%) and 89 in rural regions (15.42%), and influenza outbreaks predominantly occurred in primary schools (487 outbreaks, 84.40%). In addition, the types of pathogens were alternately prevalent, with influenza B virus (241 outbreaks, 41.77%) and A/H3N2 virus (232 outbreaks, 40.21%) as predominant subtypes. Conclusions Influenza outbreaks mainly occurred in winter in Zhejiang Province from 2013 to 2022, and primary schools were main places of influenza outbreaks, while influenza B virus and A/H3N2 virus were predominant subtypes. It is necessary to reinforce the surveillance and report of influenza-like illness in schools and improve the coverage of influenza vaccination to prevent influenza outbreaks.

Objective:To explore the effect of peripelvic multi-joint comprehensive exercise in late pregnancy in pregnant women.Methods:From July 2020 to June 2021, 110 first-time pregnant women who were registered at the People's Hospital of Bozhou were selected as the study subject using convenience sampling. According to the random number table method, study subjects were randomly divided into a study group and a control group, with 55 cases in each group. Pregnant women in the study group underwent peripelvic multi-joint comprehensive exercise, while those in the control group underwent routine walking. We compared the adverse events, pain, pelvic ligament elasticity, Bishop score, pregnancy days, and fetal position after exercise between two groups of pregnant women.Results:The study group ultimately included 52 pregnant women, while the control group ultimately included 51 pregnant women. Both groups of pregnant women did not experience abnormal bleeding after exercise. The number of pregnant women in the study group experiencing pain after exercise one day before delivery was lower than that in the control group, with a statistically significant difference ( P<0.05). The pelvic ligament elasticity of pregnant women in the study group during delivery was better than that of the control group, and the Bishop score was higher than that of the control group, with statistically significant differences ( P<0.05). There was no statistically significant difference in the number of pregnancy days between the two groups of pregnant women ( P>0.05). The number of fetuses in the occipital anterior position during admission to labor in the study group was higher than that in the control group, with a statistically significant difference ( P<0.05) . Conclusions:Prenatal multi-joint and deep muscle and ligament exercises through peripelvic multi-joint comprehensive exercise can strengthen the elasticity of the pelvic ligaments in pregnant women, adjust the fetal pelvic entry angle, and reduce the occurrence of post exercise pain, which is worthy of clinical practice.

Objective:To analyze the number of appeals volume and causes for complaints received by the government hotline against a hospital in Yangzhou during the pandemic of novel coronavirus pneumonia(hereinafter referred to as COVID-19), so as to provide reference for handling such hotline complaints during pandemics.Methods:Retrospective comparative analysis was made on the " 12345" government hotline work orders received from July 28, 2020 to August 28, 2020(routine prevention and control period) and July 28, 2021 to August 28, 2021(pandemic closure and control period). A descriptive analysis was made on the cause types of complaints and the distribution of departments in question, along with an analysis of the correlation between the cumulative number of cases of pandemic development and the number of complaints using Spearman rank correlation method.Results:The number of work orders for a hospital in Yangzhou during the pandemic control period(659 cases) was 7.7 times higher than that in the routine control period(76 cases). Management problems accounted for 96.7%(637 cases) in the level-1 type of the causes of complaints during the closure and control period of the pandemic, and workflow problems accounted for 90.9%(599 cases) in the level-2 type, which increased by 28.3 and 27.7 percentage points respectively compared with the routine prevention and control period; The highest proportion in the level-3 type of causes for complaints during the closure and control period of the pandemic was administrative management, accounting for 87.9%(579 cases). The departments being complained the most during the pandemic incubation period, outbreak period and recovery period of the pandemic were the fever clinic, oncology department and discharge center respectively. The cumulative number of cases of pandemic development was positively correlated with the number of complaints.Conclusions:During the COVID-19, the handling of the government hotline should be analyzed along with the causes of complaints, focusing on patients′ demands, providing timely feedback, developing collaborative management measures, and achieving accurate policy implementation.

Objective:To compare the efficacy of haplotype hematopoietic stem cell transplantation (HIDT) and sibling matched hematopoietic stem cell transplantation (MSDT) in the treatment of complete remission (CR) acute T-lymphoblastic leukemia (T-ALL) .Methods:We retrospectively analyzed the clinical characteristics and outcomes of 98 patients who underwent HSCT in Hebei Yanda Ludaopei hospital with HID ( n=81) or ISD ( n=17) between May 2012 and May 2016. Results:The incidence of grades 2-4 and 3-4 acute-versus-host disease 100 days after HSCT were 51.9% (95% Confidence interval [ CI] 42.0%-64.0%) vs 29.4% (95% CI 14.1%-61.4%) ( P=0.072) and 9.8% (95% CI 5.1%-19.1%) vs 11.8% (95% CI 3.2%-43.3%) ( P=1.000) for HIDT and MSDT. The 100-day cumulative incidences of CMV and EBV viremia were 53.1% (95% CI 43.3%-65.2%) vs 29.4% (95% CI 14.1%-61.4%) ( P=0.115) and 35.8% (95% CI 26.8%-47.9%) vs11.8% (95% CI 3.2%-43.3%) ( P=0.048) . The 5-year overall survival, leukemia-free survival, cumulative incidences of relapse, and no-relapse mortality were 60.5% (95% CI 5.4%-49.0%) vs 68.8% (95% CI 11.8%-40.0%) ( P=0.315) , 58.0% (95% CI 5.5%-46.5%) vs 68.8% (95% CI 11.8%-40.0%) ( P=0.258) , 16.1% (95% CI 9.8%-26.4%) vs 11.8% (95% CI 3.2%-43.3%) ( P=0.643) , 25.9% (95% CI 17.9%-37.5%) vs 19.4% (95% CI 6.9%-54.4%) ( P=0.386) for HIDT and MSDT, respectively. Conclusion:HID could be a valid alternative donor for patients with T-ALL in CR lacking an identical donor.

Objective:To study the clinical efficacy of chimeric antigen receptor T-cell (CART) treatment followed by a second allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with B-cell acute lymphoblastic leukemia (ALL) who relapsed following the first HSCT.Methods:Retrospective analysis of the clinical characteristics and prognosis of 41 patients with B-cell ALL who received a second allo-HSCT from October 2015 to June 2020 in Hebei Yanda Lu Daopei Hospital. After the first HSCT, all patients received CD19-CART, or CD22-CART treatment following a relapse of bone marrow morphology or extramedullary leukemia.Results:A total of 41 patients (male, 21; female, 20) were included in this study. The median age at the second HSCT was 16 (3-46) years. There were 31 cases of bone marrow recurrence (75.6%) , 5 cases of extramedullary recurrence (12.2%) , and 5 cases of bone marrow and extramedullary recurrences (12.2%) . After relapse, 35 patients (85.4%) received CD19-CART treatment, 2 patients received CD22-CART treatment (4.9%) , and 4 patients received CD19-CART and CD22-CART treatments (9.8%) . The expected 3-year overall survival (OS) , leukemia-free survival, cumulative relapse incidence, and non-relapse mortality (NRM) of patients after the second HSCT were 48.9% (95% CI 23.0%-70.6%) , 41.8% (95% CI 17.3%-64.9%) , 8.8% (95% CI 2.9%-26.4%) , and 51.1% (95% CI 31.2%-83.6%) , respectively. The 1-year OS of patients who relapsed ≤6 months and >6 months after the first HSCT were 45.0% (95% CI 12.7%-73.5%) and 75.0% (95% CI 51.4% -88.8%) ( P=0.017) , respectively. Conclusion:CART bridging in the second HSCT enables some B-cell ALL patients who relapsed after the first HSCT to achieve long-term survival. However, because of the high NRM, further modifications could help improve the outcome.
