ObjectiveTo understand the epidemiological distribution and gene evolutionary variation of influenza A (H3N2) viruses in Fengxian District, Shanghai, in the surveillance year of 2023, and to provide a reference basis for influenza prevention and control. MethodsThe prevalence of influenza virus in Fengxian District in the 2023 influenza surveillance year (April 2023‒March 2024) was analyzed. The hemagglutinin (HA) gene, neuraminidase (NA) gene, and amino acid sequences of 75 strains of H3N2 influenza viruses were compared with the vaccine reference strain for similarity matching and phylogenetic evolutionary analysis, in addition to an analysis of gene characterization and variation. ResultsIn Fengxian District, there was a mixed epidemic of H3N2 and H1N1 in the spring of 2023, with H3N2 being the predominant subtype in the second half of the year, and Victoria B becoming the predominant subtype in the spring of 2024. A total of 75 influenza strains of H3N2 with HA and NA genes were distributed in the 3C.2a1b.2a.2a.2a.3a.1 and B.4 branches, with overall similarity to the reference strain of the 2024 vaccine higher than that of the reference strain of the 2022 and 2023 vaccine. Compared with the 2023 vaccine reference strain, three antigenic sites and one receptor binding site were changed in HA, with three glycosylation sites reduced and two glycosylation sites added; where as in NA seven antigenic sites and the 222nd resistance site changed with two glycosylation sites reduced. ConclusionThe risk of antigenic variation and drug resistance of H3N2 in this region is high, and it is necessary to strengthen the publicity and education on the 2024 influenza vaccine and long-term monitoring of influenza virus prevalence and variation levels.

Objective:To explore the efficacy and safety of domestic bortezomib in combination with lenalidomide and dexamethasone in the treatment of newly diagnosed multiple myeloma (NDMM) .Methods:This multicenter, prospective, single-arm clinical study included 126 patients with NDMM admitted to seven hospitals between December 2019 and January 2022. All patients received domestic bortezomib in combination with lenalidomide and dexamethasone (BLD regimen), and the efficacy, prognostic factors, and safety were analyzed.Results:Among the 126 patients with NDMM, 118 completed four cycles of treatment, with an overall response rate (ORR) of 93.22% (110/118) and a ≥very good partial response (VGPR) rate of 68.64% (81/118). Ultimately, 114 patients completed at least eight cycles of treatment, with an ORR of 92.98% (106/114) and a ≥VGPR rate of 77.19% (88/114). Eighteen patients underwent autologous hematopoietic stem cell transplantation after completing 6-8 cycles of the BLD regimen, with an ORR of 100% (18/18) and a ≥VGPR rate of 88.9% (16/18). The proportion of patients achieving ≥VGPR increased with the treatment duration, and factors such as staging and age did not significantly affect efficacy. Single-factor analysis showed that R2-ISS stage Ⅲ/Ⅳ, blood calcium >2.27 mmol/L, and failure to achieve VGPR after six cycles were adverse prognostic factors for progression-free survival (PFS) ( P<0.05), whereas failure to achieve VGPR after six cycles was an adverse prognostic factor for overall survival (OS) ( P<0.001). Multifactor analysis demonstrated that failure to achieve VGPR after six cycles is an independent adverse prognostic factor for PFS ( P=0.002). The incidence of hematologic adverse reactions was 16.7% (19/114), and nonhematologic adverse reactions were mainly mild to moderate, with no significant cardiac or renal adverse reactions observed. Conclusion:The BLD regimen is effective in treating NDMM, in which patients with high-risk genetic features are still achieving a high ≥VGPR rate, and the overall safety is good.

Objective:To analyze the epidemic characteristics of reported tuberculosis incidence in Kashgar from 2015 to 2022, and use the seasonal autoregressive integrated moving average (SARIMA) model to predict the incidence, providing references for the local control of pulmonary tuberculosis.Methods:The reported incidence data of tuberculosis in the Kashgar area of Xinjiang from January 2015 to August 2023 were collected through the"Infectious Disease Monitoring System", a subsystem of the "Chinese Disease Prevention and Control Information System". The epidemic characteristics of reported incidence in this area from 2015 to 2022 were analyzed. Two SARIMA models of monthly reported incidence number and rate were established. The prediction performance of the two models was evaluated using the reported incidence data of tuberculosis from January 2023 to August 2023. The χ2 test was used to analyze population characteristics, and the Cochran-Armitage trend test was used to analyze annual incidence. Results:From 2015 to 2022, 133 972 cases of pulmonary tuberculosis were reported in Kashgar, with a yearly reported incidence rate of 383.64/100 000, showing a rising trend ( TCA=77.03, P<0.001) and then a declining trend ( TCA=176.16, P<0.001). The proportion of pathogenic positive pulmonary tuberculosis had increased yearly ( TCA=132.66, P<0.001). The reported onset time was concentrated from January to June each year, with a peak in April. Yengisar County, Zepu County and Yopurga County had the highest reported incidence rate in Kashgar. The sex ratio of men to women was 1.03∶1, and the reported incidence rate of men was higher than that of women ( χ2=27.04, P<0.001). The reported incidence rate of the group aged 60 years and older was the highest. The patient′s occupation was mainly farmers (84.99%). The average relative errors of the SARIMA ( 1, 1, 2) ( 0, 1, 1) 12 model and SARIMA ( 0, 1, 1)( 0, 1, 1) 12 model in predicting the reported monthly incidence number and rate were 11.67% and -9.81%, respectively. Both models had good prediction accuracy (MAPE=33.55%, MAPE=38.22%). Conclusion:The average reported incidence rate of pulmonary tuberculosis in the Kashgar area shows a rising trend first and then a declining trend. The patients are mainly men and farmers, and attention should be paid to the prevention and control of tuberculosis among the elderly in winter and spring. The SARIMA ( 1, 1, 2) ( 0, 1, 1) 12 model and SARIMA ( 0, 1, 1)( 0, 1, 1) 12 model can fit the trend of reported tuberculosis incidence in the Kashgar area well and have good predictive performance.

Objective:To investigate the central mechanism of moxibustion in treating chronic inflammatory visceral pain(CIVP)and its analgesic effect from the perspective of the p38 mitogen-activated protein kinase(MAPK)/Ets-like transcription factor 1(ELK1)signaling pathway in the spinal cord. Methods:Clean-grade male Sprague-Dawley rats were randomly divided into a normal group,a model group,a herb-partitioned moxibustion(HPM)group,a sham-HPM group,a p38 MAPK inhibitor group,and a dimethyl sulfoxide(DMSO)group.CIVP rat models were prepared using an enema mixture of 2,4,6-trinitrobenzene sulfonic acid solution and 50%ethanol.The HPM group was treated with HPM;the sham-HPM group was treated the same as the HPM group,but the moxa cones were not ignited;rats in the p38 MAPK inhibitor group received L5-L6 intrathecal injection of p38 MAPK inhibitor(SB203580);rats in the DMSO group received L5-L6 intrathecal injection of 2%DMSO.Abdominal withdrawal reflex(AWR),mechanical withdrawal threshold(MWT),and thermal withdrawal latency(TWL)were used to observe pain-related behaviors in each group.Hematoxylin-eosin staining was used to observe the morphological changes in rat colon tissue.Western blotting and real-time quantitative reverse-transcription polymerase chain reaction were used to detect the phosphorylated protein and mRNA expression of apoptosis signal-regulating kinase 1(ASK1),MAPK kinase(MKK)3/6,p38 MAPK,ELK1,and mitogen and stress-activated protein kinase 1(MSK1)in the spinal cord. Results:Compared with the normal group,CIVP rats had severe colonic inflammatory injuries,and the pathological injury scores increased significantly,along with increased AWR scores under different colorectal distension(CRD)stimulation pressures and decreased MWT and TWL;the mRNA and phosphorylated protein expression of p38 MAPK,ELK1,MSK1,ASK1,MKK3,and MKK6 all increased in the spinal cord(P<0.01).After HPM treatment,the colon injuries were repaired,and the pathological injury scores decreased;under different CRD stimulation pressures,the AWR scores decreased,and the MWT and TWL increased;the mRNA and phosphorylated protein expression of p38 MAPK,ELK1,ASK1,and MKK3 in the spinal cord also decreased,with statistically significant differences compared with the model group and the sham-HPM group(P<0.01).There were no significant differences in the above indicators between the HPM group and the p38 MAPK inhibitor group(P>0.05),and the same was true regarding the comparisons between the model group and the DMSO group. Conclusion:HPM exerted analgesic effects via downregulating the mRNA and phosphorylated protein expression of ASK1,MKK3,p38 MAPK,and ELK1 in the spinal cord of CIVP rats.The inhibition of spinal p38 MAPK/ELK1 signaling pathway activation may be one of the mechanisms by which HPM relieves pain in CIVP.

Objective:
Autism spectrum disorder (ASD) is a neurodevelopmental disorder with onset in infancy. Early intervention is critical to improve the prognosis for these children. E-health interventions have tremendous potential. This review aimed to determine the status and effectiveness of family interventions for parents of children aged 0–6 years with ASD in the context of e-health.
Methods:
The review methodology was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. PubMed, Web of Science, and China National Knowledge Infrastructure were searched from inception to June 2022. The searches were limited to children with ASD of the age range between 0 and 6 years. We collated the available information and used descriptive statistics to analyze the synthesized data.
Results:
Our initial search identified 3,672 articles, of which 30 studies met the inclusion criteria. The 30 articles selected were released between 2012 and 2022. All articles are in English. Most articles reviewed were from high-income countries (27/30, 90.0%), especially from the United States (16/30, 53.3%). Four major themes emerged from the 30 studies that matched the inclusion criteria, as follows: 1) type of e-health interventions, 2) duration of interventions, 3) clinical aspects of e-health interventions, and 4) evidence for intervention effectiveness, looking into the positive, negative, and mixed findings of previous studies.
Conclusion
These findings suggest that a wide variety of e-health interventions may actually help support both children with ASD aged 0–6 years and their parents.
8.The guiding role of microcirculation monitoring in the treatment of septic shock
Chinese Pediatric Emergency Medicine 2023;30(5):380-383
Septic shock is the most critical stage of sepsis, and the core of the treatment is improving tissue hypoperfusion.In addition to the improvement of large circulation by fluid resuscitation, the microcirculation also need to be improved, then proper vasoactive drugs should be applied to different types of shock to meet the needs of the body for perfusion.The condition of septic shock progresses rapidly, and the microcirculation in different pathophysiological stages is different, which increases the difficulty of rational use of vasoactive drugs.Monitoring and accurate evaluation of peripheral microcirculation may provide guidance for individualized treatment of septic shock.

Objectives:This study aimed to assess the efficacy and safety of bendamustine in combination with rituximab (BR regimen) for the treatment of newly diagnosed indolent B-cell non-Hodgkin's lymphoma (B-iNHL) and elderly mantle cell lymphoma (eMCL) .Methods:From December 1, 2020 to September 10, 2022, a multi-center prospective study was conducted across ten Grade A tertiary hospitals in Shandong Province, China. The BR regimen was administered to evaluate its efficacy and safety in newly diagnosed B-iNHL and eMCL patients, and all completed at least four cycles of induction therapy.Results:The 72 enrolled patients with B-iNHL or MCL were aged 24-74 years, with a median age of 55 years. Eastern Cooperative Oncology Group (ECOG) performance status scores of 0-1 were observed in 76.4% of patients, while 23.6% had scores of 2. Disease distribution included follicular lymphoma (FL) (51.4% ), marginal zone lymphoma (MZL) (33.3% ), eMCL (11.1% ), and the unknown subtype (4.2% ). According to the Ann Arbor staging system, 16.7% and 65.3% of patients were diagnosed with stage Ⅲ and stage Ⅳ lymphomas, respectively. Following four cycles of BR induction therapy, the overall response rate was 98.6%, with a complete response (CR) rate of 83.3% and a partial response (PR) rate of 15.3%. Only one eMCL patient experienced disease progression during treatment, and only one FL patient experienced a relapse. Even when evaluated using CT alone, the CR rate was 63.9%, considering the differences between PET/CT and CT assessments. The median follow-up duration was 11 months (range: 4-22), with a PFS rate of 96.8% and an OS rate of 100.0%. The main hematologic adverse reactions included grade 3-4 leukopenia (27.8%, with febrile neutropenia observed in 8.3% of patients), grade 3-4 lymphopenia (23.6% ), grade 3-4 anemia (5.6% ), and grade 3-4 thrombocytopenia (4.2% ). The main non-hematologic adverse reactions such as fatigue, nausea/vomiting, rash, and infections occurred in less than 20.0% of patients.Conclusion:Within the scope of this clinical trial conducted in China, the BR regimen demonstrated efficacy and safety in treating newly diagnosed B-iNHL and eMCL patients.
