Objective: To investigate the prevalence of hypertension among primary and middle school students living in Suzhou City, Jiangsu Province, so as to provide insights into comprehensive hypertension control among children and adolescents. Methods: Primary and middle school students at ages of 7 to 17 years were recruited for a questionnaire survey in Suzhou City using the stratified cluster random sampling method from September to December, 2020, and the height and body weight were measured. Blood pressure was measured at three separate clinic visits according to the national criteria Reference of Screening for Elevated Blood Pressure among Children and Adolescents Aged 7-18 Years ( WS/T 610-2018 ), and the detection of elevated blood pressure was estimated at three separate visits. In addition, factors affecting elevated blood pressure were identified. Results: A total of 3 713 students were enrolled, including 1 924 boys ( 51.82% ) and 1 789 girls ( 48.18% ). The detection of elevated blood pressure was 13.63%, 5.36%, and 3.37% at three separate visits, respectively, and the prevalence of hypertension ( elevated blood pressure at all three visits ) was 3.37%. The detection rates of elevated blood pressure were all higher at three visits ( 16.90%, 8.40%, and 5.26% ) among students at ages of 12 to 17 years than among students at ages of 7 to 11 years ( 9.65%, 1.67%, and 1.07%, P<0.05 ). The detection of elevated blood pressure was significantly higher in boys ( 15.23% ) than in girls (11.91%) at the first visit ( P<0.05 ), while no significant differences were seen at the second or third visit ( P>0.05 ). In addition, higher detection rates of elevated blood pressure were seen in obese ( 27.62%, 11.51%, and 7.06% ) and overweight students ( 17.45%, 6.95%, and 4.85% ) than in students with normal weight ( 9.44%, 3.54%, and 2.15% ) at all three visits, and greater detection rates of elevated blood pressure were found in obese students than in overweight students at the first and second visits ( P<0.017 ). Conclusions The prevalence of hypertension was 3.37% based on three separate visits among primary and middle school students in Suzhou City. Measurement of blood pressure at three separate visits within different days is effective to reduce the false positive rate of hypertension and decrease misdiagnosis among children and adolescents.

Objective: To explore the characteristics of overweight children s attention bias to food cues, so as to provide a theoretical basis for the behavior and life intervention of overweight children. Methods: From September to October 2017, 28 normal weight children and 28 overweight children in grades 3 to 4 of a primary school in Shenyang were screened by body mass index (BMI). The point detection paradigm was used to evaluate the attention bias of overweight children to food cues. Results: There was no significant difference between overweight children and control children in the score of attention bias to food cues [ F (1,52)=0.01, P> 0.05 , ηp 2 <0.01]; there was significant difference between overweight children and normal weight children in the score of facilitated attention to food cues[ F (1,52)=5.94, P<0.05, ηp 2 =0.10], normal weight children had higher score of facilitated attention to food cues than that of overweight children; there was significant difference between overweight children and normal weight children in the score of difficulty in disengaging to food cues[ F (1,52)=7.74, P<0.05, ηp 2 =0.13], overweight children had higher score of difficulty in disengaging to food cues than that of normal weight children. Conclusion Compared with normal weight children, overweight children didn t have higher attention bias to food cues; in the specific indicators of attention bias to food cues, normal weight children are more alert to food cues, while overweight children are more difficult to remove attention from food cues.

Objective:To compare the value of difference between thromboelastogram (TEG), coagulation function and mean platelet volume (MPV)/platelet count (PLT) ratio in sepsis patients with short-term prognosis.Methods:A total of 271 patients with sepsis admitted to the Affiliated Hospital of Xuzhou Medical University from January 2020 to September 2021 were retrospectively analyzed. The clinical data of the patients were recorded, and the SOFA score and APACHE Ⅱ score were calculated. The patients were followed up within 28 days and were divided into the survival group and death group. The TEG, coagulation function and MPV/PLT ratio were compared between the two groups. The independent prognostic factors of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio were confirmed by Logistic regression analysis. The combination of Angle + CI + AT-Ⅲ + D-Di +MPV/PLT ratio was established, and the ROC curve was drawn to evaluate the prognostic value of Angle, CI, AT-Ⅲ and D-Di combined with MPV/PLT ratio in patients with sepsis.Results:The mortality rate of patients with sepsis was 42.4%. The D-Di and MPV/PLT ratio of the death group were significantly higher than those of the survival group, and the differences were statistically significant. Angle, CI and AT-III in the death group were significantly lower than those in the survival group, and the differences were statistically significant. Logistic regression analysis showed that Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio were independent predictors of the prognosis of patients with sepsis (all P < 0.05) . The area under the curve of the combined detection of Angle, CI, AT-Ⅲ, D-DI and MPV/PLT ratio to evaluate the prognosis of sepsis at 28 days was 0.931, which was larger than that of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio alone (0.755, 0.790, 0.776, 0.729 and 0.746). The sensitivity and specificity of the combination of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio were 83.5% and 91.0%, which were also higher than those of the single index . Conclusions:Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio are independent prognostic predictors of patients with sepsis. The combination of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio has high sensitivity and specificity in evaluating the prognosis of sepsis.

Objective:To investigate the effect of Xuanbai Chengqi Decoction (XBCQT) on lung-gut injury and intestinal function, and analyze its effect on intestinal flora in sepsis mice.Methods:C57 male mice were randomly divided into three groups with 12 mice in each group: control group, model group and treatment group. The sepsis model was prepared by intra-peritoneal injection of lipopolysaccharide (LPS) 5 mg/kg. XBCQT was administered by gavage 24 h before, 0.5 h after and 12 h after modeling. The lung, colon and blood samples were collected at 24 h after modeling. The pulmonary and intestinal inflammatory cytokine content of interleukin-1β (IL-1β), IL-6, tumor necrosis factor α (TNF-α) and monocyte chemoattractant protein (MCP-1) was measured by real-time fluorescence quantitative PCR. HE staining was used to evaluate the structural damage and changes of lung and gut, and Western blot and Immunohistochemistry methods were used to analyze the expression of occludin and claudin-1 in intestinal epithelium. Finally, the plasma endotoxin content of each group was tested by Limulus test kit. Fecal DNA of mice was extracted and the changes of intestinal flora in sepsis mice were detected by 16S rDNA quantitative PCR. The measurement data among the three groups were compared by one-way analysis of variance.Results:(1) XBCQT significantly reduced the pulmonary inflammatory cytokine IL-1β, IL-6, TNF-α and MCP-1 expression (all P<0.05), and attenuated lung injury. (2) Compared to the model group, the treatment group exhibited a reduction in intestinal damage and a decrease in the intestinal inflammatory cytokines (all P<0.05). XBCQT increased the expression of epithelial tight junction and mucin of colon, and improved the intestinal epithelium barrier function. (3) XBCQT treatment decreased the content of endotoxin in plasma of sepsis mice ( P<0.05), promoted the growth of beneficial bacteria Akkermansia muciniphila and reduced the expression of Enterococcus in the intestine of sepsis mice (all P<0.05). Conclusions:XBCQT can significantly improve the intestinal inflammatory injury, regulate the intestine epithelium barrier and improve the intestinal function in sepsis mice.

Objective:To investigate the relationship between serum free triiodothyronine (FT 3) and the severity and prognosis of elderly patients with coronavirus disease 2019 (COVID-19). Methods:Clinical data of the elderly patients aged≥65 years old with COVID-19 who were admitted to the Ninth People′s Hospital of Wuxi from December 27, 2022 to January 18, 2023 were collected. The laboratory examinations of the non-severe and the severe/critical groups were compared. Patients were divided into group T1 (FT 3<2.51 pmol/L), group T2 (FT 3=2.51 to 2.95 pmol/L, ), and group T3 (FT 3>2.95 pmol/L) according to the FT 3 level. Independent sample t test was used for comparison between groups. Logistic regression analysis was performed to evaluate the risk factors for severe/critical disease, and to analyze the risk of severe/critical COVID-19 in elderly patients with different FT 3 levels. The receiver operator characteristic (ROC) curve was drawn to analyze the predictive value of FT 3 on the occurrence of severe/critical disease in patients. Kaplan-Meier survival curve and log-rank test were used to analyze the 30-day survival rate of elderly COVID-19 patients. Results:Among the 190 patients, the FT 3 level in the severe/critical group was (2.54±0.30) pmol/L, which was significantly lower than that in the non-severe group ((2.91±0.69) pmol/L), and the difference was statistically significant ( t=-3.42, P=0.001). Elevated serum FT 3 level was a protective factor for severe/critical disease in elderly COVID-19 patients (odds ratio ( OR)=0.139, 95% confidence interval ( CI) 0.034 to 0.577, P=0.007). There were 66 patients in the T1 group, 61 in the T2 group and 63 in the T3 group, respectively. After adjusted for sex, age, history of lung diseases, history of cardiac diseases, history of hypertension, history of diabetes mellitus, history of cerebral infarction, white blood cell count, lactate dehydrogenase, D-dimer, free thyroxine and thyrotropin, the risk of developing severe/critical disease in group T1 and group T2 were 10.982 folds and 3.695 folds of that in group T3, respectively (both P<0.05). The area under ROC curve of FT 3 of predicting severe/critical COVID-19 in the elderly patients was 0.731. The sensitivity and specificity were 0.733 and 0.659, respectively. The cut-off value was 2.53 pmol/L. The 30-day survival rate in patients with FT 3<2.53 pmol/L was significantly lower than that in patients with FT 3≥2.53 pmol/L ( χ2=13.49, P<0.001). Conclusions:The elevated level of FT 3 is a protective factor for progression to severe/critical disease in elderly patients with COVID-19. The evaluation of serum FT 3 could predict the severity and prognosis of elderly COVID-19 patients.

Objective: Adiponectin (APN) is an endogenous cytokine that mediates the development and progression of various tumors through its receptors (AdipoRs). The present study aimed to detect the expression and distribution of APN and its receptors (AdipoR1 and AdipoR2) in tongue squamous cell carcinoma (TSCC). Moreover, we explored whether the locoregional expression of APN was reg-ulated by HIF-1α in the hypoxic microenvironment. Methods: The expression and distribution of APN and its receptors in TSCC tissues were analyzed by immunohistochemical. Lentiviral expression vector for HIF-1α shRNA was constructed and stably transfected in TSCC cells to knock down HIF-1α expression. The mRNA and protein expression levels of APN and its receptors were detected using RT-PCR and Western blot, respectively, after hypoxic treatment. Results: The locoregional expression of APN and AdipoR1, but not AdipoR2, was upregulated at the early stages of T1, T2, and/or N0 stage, respectively, in tumor tissues compared to that in control paracancer-ous tissues (P<0.05 or P<0.01). The expression of APN and AdipoR1, but not AdipoR2, in TSCC cells was up-regulated on hypoxic treat-ment. Moreover, the expression of APN and AdipoR1 was down-regulated after shRNA knockdown of HIF-1α under hypoxia. Conclu-sions: The APN-AdipoR1 signaling pathway was activated and regulated by HIF-1α in the hypoxic environment of TSCC tissues.

Objective:To explore the application of venetoclax in transplantation of patients with refractory acute myeloid leukemia (AML).Methods:The diagnosis and treatment process of a patient with refractory AML who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) under venetoclax and hypomethylating agents bridging myeloablative preconditioning regimen after induction therapy failure in the First Affiliated Hospital of Soochow University in March 2020 were retrospectively analyzed.Results:The patient was a 28-year-old female who was diagnosed with refractory AML. The patient was initially given induction chemotherapy with IA (idarubicin+cytarabine) (3+7) regimen, but the disease did not relieve, then the induction chemotherapy with CLAG (cladribine+cytarabine+granulocyte colony stimulating factor) regimen was given, but the disease still did not relieve. After chemotherapy with venetoclax and hypomethylating agents bridging myeloablative preconditioning regimen, salvage haploid allo-HSCT was performed. Re-examination of bone marrow showed remission, and implantation was successful. The patient was followed up for 100 days and had sustained remission, and no transplantation complications occurred.Conclusion:For refractory AML patients who have failed primary induction therapy, the use of venetoclax and hypomethylating agents bridging myeloablative preconditioning regimen can be used as a preferred solution for salvage allo-HSCT.
