Objective:To explore and analyze the characteristics and influencing factors of language development in children with attention deficit hyperactivity disorder (ADHD).Methods:A case-control study was used, from May 2021 to August 2023, patients diagnosed with attention deficit hyperactivity disorder (ADHD) were enrolled in the mental health clinic of the Children′s Hospital Affiliated to the Capital Institute of Pediatrics. The language ability of 272 children with ADHD and 117 healthy children who underwent physical examination in children′s health center during the same period were tested by Diagnostic Receptive and Expressive Assessment of Mandarin-Comprehensive (DREAM-C), and the development levels of total language, receptive, expressive, semantics and syntax of the two groups were compared by independent sample t-test. The influential factors of language lag in children with ADHD were analyzed by univariate χ2 analysis and multiple logistic regression. Results:There were 272 children with ADHD, including 206 males and 66 females, with an age range of 6-8 (7.29±1.17) years. While in the control group, there were 117 healthy children, including 91 males and 26 females, with an age range of 6-8 (7.02±0.82) years. The average scores of total language, expressive and syntax of ADHD children were lower than those of healthy children [(92.73±12.47/96.36±11.04), t=-2.857, P<0.05; (84.49±13.24/87.78±15.25), t=-2.029, P<0.05; (87.93±10.26/90.27±11.05), t=2.022, P<0.05]. Univariate χ2 analysis showed that disharmonious family relationship ( χ2=4.183, P<0.05), the main caregivers were non-parents ( χ2=9.121, P<0.05), early screen exposure ( χ2=3.889, P<0.05), ADHD family history ( χ2=5.423, P<0.05) were influential factors of language development lag in ADHD children. The results of multivariate logistic regression model analysis showed that cesarean section ( OR=2.137, 95% CI: 1.078-4.379, P=0.030), disharmonious family relationship ( OR=2.659, 95% CI: 1.178-5.999, P=0.019), early screen exposure ( OR=3.556, 95% CI: 1.127-11.213, P=0.030), ADHD family history ( OR=1.959, 95% CI: 1.058-3.630, P=0.033) were risk factors for comorbidities of language development in children with ADHD. Conclusion:The total language ability, expressive and syntax scores of ADHD children lag behind those of healthy children. The delayed language development of ADHD children is related to delivery mode, family relationship, the main caregivers, early screen exposure, family history of ADHD.

Objective To analyze pathogenic microorganisms and related clinical features in patients with acute cholangitis.Methods The pathogenic microorganism culture results and related clinical data of 229 patients with acute cholangitis in People's Hospital of Haining from 2019 to 2022 were collected and analyzed.Results Among 229 patients,160(69.87%)patients were positive in bile culture,of which 58 patients were infected with multiple bacteria.A total of 227 strains of pathogenic bacteria were isolated from 160 positive bile specimens,of which 136(59.91%)strains were Gram-negative,79(34.80%)strains were Gram-positive and 12(5.29%)strains were fungi.Escherichia coli mixed with Enterococcus faecium was the most common infection(10/58,17.24%).The susceptibility rate of Gram-negative bacteria to amikacin and tigecycline was the highest,and Gram-positive bacteria were highly sensitive to linezolid,vancomycin and tigecycline.Previous biliary surgery history and cirrhosis were independent risk factors for biliary tract infection(P<0.05).Cirrhosis was an independent risk factor for co-infection(P<0.05).Conclusion The pathogenic microorganisms of acute cholangitis are complex in distribution and have some resistance to common antibiotics.Clinicians should pay close attention to patients with acute cholangitis who have a history of biliary tract surgery,cirrhosis and chronic renal insufficiency,and rationally select initial antibiotics.

Objective: To investigate the coverage of rotavirus vaccination among children under five years in Xiuzhou District of Jiaxing City, so as to provide insights into rotaviral diarrhea control. Methods: The rotavirus vaccination data of children aged two months to five years were extracted from the vaccination clinics of eight township hospitals and community health service centers through the Zhejiang vaccination information system. The coverage of rotavirus vaccination was analyzed among children with different genders, ages, types of vaccines and doses of vaccination. Results: Totally 32 752 children were included, and the coverage of rotavirus vaccination was 47.09%. The coverage of rotavirus vaccination was significantly higher in boys than in girls ( 47.65% vs. 46.46%, P<0.05 ), and a higher vaccination rate was seen in children with local household registration than in those without ( 56.76% vs. 38.75%, P<0.05 ). The vaccination rates of monovalent and pentavalent rotavirus vaccines were 36.90% and 10.18%, respectively. Totally 26 982 doses of rotavirus vaccines were vaccinated, with a mean dose of ( 0.84±1.02 ) per capita, and the vaccination rates of one, two and three doses were 20.75%, 17.37% and 8.96%, respectively. The median age was 6.00 months ( interquartile range, 3.00 months ) among children vaccinated with the first dose. Conclusions The coverage of rotavirus vaccination and full-dose vaccination are low among children under five in Xiuzhou District, with monovalent rotavirus vaccines predominant. Intensified rotavirus vaccination is therefore recommended.

Objective To understand the epidemiological characteristics of pneumoconiosis through analyzing the data of pneumoconiosis cases in Liuzhou from 2006 to 2018, and to provide a scientific basis for the prevention and control of pneumoconiosis in Liuzhou. Methods The information of pneumoconiosis cases in Liuzhou was collected through the ^“health hazard factors monitoring information system^”, a subsystem of China's disease prevention and control system, and the epidemiological characteristics of pneumoconiosis were statistically analyzed by descriptive statistics. Results A total of 160 cases of pneumoconiosis was collected, mainly stage I silicosis, accounting for 70.0% of total cases (n=112). Most of the cases were from the metal smelting and rolling industry, accounting for 82.5% of total cases (n=132). The occupation of patients was mainly smelting and auxiliary work, sintering, and mining, accounting for 23.13% (n=37), 27.50% (n=44) and 18.13% (n=29) of the total number of pneumoconiosis cases, respectively. Among them, 83.75% (n=134) were from large-scale enterprises. Most of the pneumoconiosis cases had 15 to 35 years of dust exposure, with an average dust exposure of 23.78±10.36 years. The age of onset was mainly concentrated in 45 to 60 years old, and the average age of onset was 55.61±10.28 years. Conclusion The cases of pneumoconiosis in Liuzhou existed in sporadic form in recent years, and the cases were mainly concentrated in large metal smelting enterprises, with smelting and auxiliary workers and sintering workers being the most serious. It is necessary to strengthen the occupational health management of large metal smelting enterprises to effectively prevent and control the occurrence of pneumoconiosis.

Clostridioides difficile is a key pathogen of antibiotic related diarrhea and hospital associated infection, causing several outbreaks in Europe and North Americans and resulting in severe disease burden. However, the standardized diagnostic principle and detection specifications in C. difficile infection (CDI) survey are limited in China, and the infection rate and disease burden of CDI in China are unclear. Therefore, National Institute for Communicable Disease Control and Prevention,National Institute for Communicable Disease Control and Prevention, Chinese Center for Disease Control and Prevention, together with another 11 institutions, draft the group standard entitled "Diagnosis of Clostridium difficile infection (T/CPMA 008-2020)" of Chinese Preventive Medicine Association. Based on the principle of "legality, scientificity, advancement, and feasibility", this standard clarifies risk factors, diagnosis principles, diagnoses and differential diagnoses in order to improve the accuracy of CDI diagnosis in clinical practice, guide the surveillance for CDI, and understand the infection rate and disease burden of CDI in China .

Chimeric antigen receptor T cell (CAR T) therapies have achieved unprecedented efficacy in B-cell tumors, prompting scientists and doctors to exploit this strategy to treat other tumor types. Acute myeloid leukemia (AML) is a group of heterogeneous myeloid malignancies. Relapse remains the main cause of treatment failure, especially for patients with intermediate or high risk stratification. Allogeneic hematopoietic stem cell transplantation could be an effective therapy because of the graft-versus-leukemia effect, which unfortunately puts the patient at risk of serious complications, such as graft-versus-host disease. Although the identification of an ideal target antigen for AML is challenging, CAR T therapy remains a highly promising strategy for AML patients, particularly for those who are ineligible to receive a transplantation or have positive minimal residual disease. In this review, we focus on the most recent and promising advances in CAR T therapies for AML.

Objective: To learn the knowledge,attitude and practice（KAP）of primary healthcare workers on influenza vaccine and 23-valent pneumonia vaccine in Xiuzhou District of Jiaxing,and to provide basis for vaccination of influenza vaccine and 23-valent pneumonia vaccine. Methods: From November 2018 to January 2019,the primary healthcare workers from eight community health service centers in Xiuzhou District were selected by multi-staged random sampling method. A self-designed questionnaire was used to investigate the KAP of influenza vaccine and 23-valent pneumonia vaccine among primary healthcare workers. Logistic regression analysis was employed to select the influencing factors for vaccination and recommendation behaviors of primary healthcare workers. Results: Totally 105 healthcare workers（95.45%）completed the survey. Among them,86（81.90%）and 76（72.38%）workers believed influenza vaccine and 23-valent pneumonia vaccine effective;87（82.85%）and 88（83.81%）workers believed the two vaccines safe;82（78.10%）and 58（55.24%）workers knew the vaccination procedures;58（55.24%）and 34（32.38%）workers knew the key recommended population of vaccines;77（73.33%）workers knew that the vaccine costs could be paid by medical insurance. The vaccination rate of influenza or（and）pneumococcal vaccine among the respondents was 27.62%,and the recommendation rate was 46.67%. The results of multivariate logistic regression analysis showed that healthcare workers who were female（OR=7.250,95%CI：1.388-37.883）,believed the two vaccines effective（OR=4.390,95%CI：1.167-16.515）,believed the two vaccines safe（OR=11.977,95%CI：2.417-59.343）and knew the payment method of vaccine cost（OR=11.945,95%CI：2.924-48.793）were more likely to vaccinate;healthcare workers who majored in public health（OR=2.641,95%CI：1.338-5.214）,believed the two vaccines effective（OR=6.944,95%CI：1.655-29.134）,knew the key recommended population of vaccines（OR=4.380,95%CI：1.125-17.053）,had vaccinated the two vaccines（OR=7.902,95%CI：1.693-36.877）were more likely to recommend. Conclusion Primary healthcare workers in Xiuzhou District have less awareness of influenza vaccine and 23-valent pneumonia vaccine,then have lower vaccination rate（27.62%）and recommendation rate（46.67%）.

Objective: To investigate the genetic characteristics of human norovirus (NoV) among infants under 5 years of age with diarrhea in Chaoyang District, Beijing from 2011 to 2017. Methods: NoV-positive stool samples were collected from 2011 to 2017 in this region. The partial RdRp and VP1 genes were amplified and sequenced.
