Objective To explore the relationship between different obesity indicators and carotid intima-media thickness(CIMT)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 1762 T2DM patients who visited the Endocrinology Department of Changzhou Second People's Hospital Affiliated with Nanjing Medical University and the Integrated Traditional Chinese and Western Medicine Hospital Affiliated with Nanjing University of Traditional Chinese Medicine from January 2019 to February 2022 were enrolled in this study.They were divided into youth group(18～44 years old,n=402),middle aged group(45～59 years old,n=1032),and elderly group(≥60 years old,n=328)according to WHO age classification criteria.The influencing factors for CIMT thickening in T2DM patients were analyzed using binary logistic regression,and the evaluation of the predictive effect of different obesity indicators on CIMT thickening was evaluated by receiver operating characteristic(ROC)curves.Results The subcuta-neous fat area,visceral fat area(VFA),neck circumference(NC),BMI,WC,cardiac metabolic index(CMI),Chinese visceral fat index(CAVI),visceral fat index,triglyceride glucose index,body roundness index,lipid aggregation index,HbA1c,DBP,TC,TG,HDL-C,LDL-C were lower in the middle aged and elderly groups than in youth group(P＜0.05).Binary logistic regression showed that VFA,NC,CMI in young T2DM patients,CAVI in middle aged T2DM patients,and NC in elderly T2DM patients were influ-encing factors for CIMT thickening.ROC curve analysis showed that VFA in young T2DM patients,CAVI in middle aged T2DM patients,and NC in elderly T2DM patients had a better predictive effect on CIMT thickening,with areas under the ROC curve of 0.567,0.574,and 0.573 respectively.Conclusion VFA,CAVI,and NC have a certain predictive effect on CIMT thickening in young,middle aged,and elderly T2DM patients.

Objective: To investigate the molecular mechanism of circZNF609 targeting miR-153 to regulate the proliferation and apoptosis of diffuse large B-cell lymphoma. Methods: Fifty cases of lymphoma tissue from patients with diffuse large B-cell lymphoma who were diagnosed and treated in the First Affiliated Hospital of Zhengzhou University from July 2018 to December 2019 were collected. Thirty cases of normal lymph node tissues that were confirmed to be reactive hyperplasia by pathological diagnosis during the same period were selected as controls. Real time quantitative polymerase chain reaction (PCR) was used to detect the expression of circZNF609 in diffuse large B-cell lymphoma tissues and control hyperplasia lymph nodes. Diffuse large B-cell lymphoma OCI-LY19 cells were divided into control group (blank control), si-con group (transfected with siRNA control), si-ZNF609 group (transfected with circZNF609 siRNA), and si-ZNF609+ Anti-NC group (co-transfected with circZNF609 siRNA and inhibitor control) and si-ZNF609+ Anti-miR-153 group (co-transfected with circZNF609 siRNA and miR-153 inhibitor). Cell counting kit-8 (CCK-8) was used to detected proliferation, flow cytometry was used to detect cell cycle and apoptosis. Western blot was used to detect the protein expressions of C-caspase-3, cyclin D1, p21. The luciferase reporter system was used to identifie the relationship between circZNF609 and miR-153. Results: The expression level of circZNF609 in diffuse large B-cell lymphoma tissue was (1.44±0.22), higher than (0.37±0.14) in the control tissues (P<0.001). The cell survival rate of the si-ZNF609 group was (51.74±6.39)%, lower than (100.00±10.23)% of the control group and the (99.64±11.67)% of the si-con group (P<0.001). The proportion of cells in the G(0)/G(1) phase was (63.25±4.11)%, higher than (48.62±4.32)% of the control group and (47.12±3.20)% of the si-con group (P<0.001), the apoptosis rate was (13.36±1.42)%, higher than (3.65±0.47)% of the control group and (3.84±0.62)% of the si-con group (P<0.05). The expression levels of C-caspase-3 and p21 protein were (0.85±0.09) and (0.90±0.08), higher than (0.38±0.04) and (0.65±0.07) in the control group and (0.39±0.05) and (0.66±0.05) in the si-con group (P<0.001). The expression level of cyclin D1 protein was (0.40±0.03), lower than (0.52±0.06) of the control group and (0.53±0.04) of the si-con group (all P<0.001). CircZNF609 and miR-153 are mutually targeted. The cell survival rate of the si-ZNF609+ Anti-miR-153 group was (169.92±13.25)%, higher than (100.00±9.68)% of the si-ZNF609+ Anti-NC group (P<0.001), the ratio of cells in G(0)/G(1) phase and apoptosis rate were (52.01±3.62)% and (8.20±0.87)%, respectively, lower than (64.51±5.17)% and (14.03±1.17)% in the si-ZNF609+ Anti-NC group (P<0.001). The protein expression levels of C-caspase-3 and p21 were (0.42±0.06) and (0.52±0.06), lower than (0.80±0.07) and (0.92±0.10) of the si-ZNF609+ Anti-NC group (P<0.001). The protein expression level of cyclin D1 was (0.68±0.07), higher than (0.39±0.04) in the si-ZNF609+ Anti-NC group (P<0.001). Conclusion: Down-regulation of circZNF609 inhibits the proliferation of diffuse large B-cell lymphoma OCI-LY19 cells and induces apoptosis by targeting miR-153.

OBJECTIVE: To investigate the clinical outcomes and prognostic factors of refractory/relapsed acute myeloid leukemia (AML) patients who received allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: The clinical data of 80 refractory/relapsed AML patients who received allo-HSCT from December 2013 to June 2020 were retrospectively analyzed, including the overall survival (OS) rate, disease-free survival (DFS) rate, relapse rate, incidence of transplant-related mortality (TRM), and the related risk factors were explored. RESULTS: Hematopoietic reconstitution was obtained in all 80 patients after transplantation, the 3-year OS and DFS rates were (48.8±6.3)% and (40.8±6.7)%, respectively. The 3-year cumulative incidence of relapse and TRM were 33.8% (95%CI: 0.254-0.449) and 15.0%(95%CI: 0.114-0.198), respectively. Univariate analysis showed that non-remission (NR) status before transplantation, DNMT3A R882 mutations and grade II-IV acute graft-versus-host disease (aGVHD) had negative effects on OS and DFS. Multivariate analysis indicated that the DNMT3A R882 mutations and grade II-IV aGVHD were independent risk factors for OS (HR=0.253, 95%CI: 0.092-0.695, P=0.008; HR=5.681, 95%CI: 2.101-15.361, P=0.001) and DFS (HR=0.200, 95%CI: 0.071-0.569, P=0.003; HR=7.117, 95%CI: 2.556-19.818, P<0.001). The 3-year cumulative incidence of relapse was 71.4%(95%CI: 0.610-0.836) in genetic high-risk group, which was higher than 23.3%(95%CI: 0.147-0.370) in intermediate-risk group and 23.5%(95%CI: 0.127-0.437) in favorable-risk group (P=0.006). CONCLUSION Allo-HSCT is an effective and safe choice for refractory/relapsed AML patients. DNMT3A R882 mutations and grade II-IV aGVHD are negative prognostic factors of allo-HSCT for refractory/relapsed AML patients.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Malocclusion is one of the three most common oral diseases reported by World Health Organization(WHO). In China, its incidence rate is rising. Malocclusion seriously affects the dental and maxillofacial function, facial appearance and growth development of nearly 260 million children in China, and what is more, it affects their physical and mental health development. Malocclusion occurrence is related to genetic and environmental factors. Early treatment of malocclusion can create a good dental and maxillofacial development environment, correct abnormal growth and control the adverse effects of abnormal genetic factors. It can effectively reduce the prevalence of children's malocclusion and enhance their physical and mental health. This is an urgent need from the economic perspective of our society, so it has great practical and social significance. Experts from the project group "standard diagnose and treatment protocols for early orthodontic intervention of malocclusions of children" which initiated by China National Health Institute of Hospital Administration wrote the "China Experts' Consensus on Preventive and Interceptive Orthodontic Treatments of Malocclusions of Children", which aims to guide and popularize the clinical practice, improve the clinical theory and practice level, and accelerate the disciplinary development of early treatment of children's malocclusion in China. The consensus elaborates the harmfulness of malocclusion and the necessity of early treatment, and brings up the principles and fundamental contents. Based on the law of dental and maxillofacial development, this paper puts forward the guiding suggestions of preventive and interceptive treatments in different stages of dental development ranging from fetus to early permanent dentition. It is a systematic project to promote and standardize the early treatment of malocclusion. Through scientific and comprehensive stratified clinical practice and professional training, the clinical system of early treatment of malocclusion in China will eventually be perfected, so as to comprehensively care for children's dental and maxillofacial health, and improve their oral and physical health in China.
