Objective To investigate the clinical utility of ultrasound parameters in diagnosing neonatal annular pancreas.Methods A total of 56 neonates with descending duodenal obstruction underwent saline-contrast ultrasound examination.Ultrasonic parameters,including dilated duodenum diameter(DDD),dilated duodenum thickness(DDT),and stenosis duodenum diameter(SDD),were measured.The cases were categorized into three groups:annular pancreas(group A,n=28),descending duodenal atresia(group B,n=3),and descending duodenal septum(group C,n=25).One-way ANOVA was employed to compare statistical differences among the three ultrasonic parameters across the groups,followed by LSD-t test for pairwise comparisons between two groups showing significant differences.Receiver operating characteristics analysis was conducted to calculate the area under the curve and determine the cut-off value if there were statistically significant differences observed.Results In group A,group B,group C,the diameters of DDD were measured as(23.2±2.4)mm,(25±1.0)mm,(19.4±2.6)mm,respectively.When comparing these three groups,there was a statistically significant difference between group A or group B and group C in terms of DDD diameter measurements(t=5.7,P＜0.05;t=3.793,P＜0.05).However,no statistically significant difference was observed between group A and group B for DDD diameter measurements(t=1.232,P＞0.05).The corresponding values for DDT were measured as(3.0±0.6)mm,(3.2±0.4)mm,and(2.4±0.3)mm,respectively.When comparing these three groups,the results showed a statistically significant differ-ence between either Group A or Group B compared to Group C in terms of DDT measurement(t=4.695,P＜0.05;t=2.778,P＜0.05).However,no statistically significant difference was found between Group A and Group B regard-ing the measurement of DDT(t=0.666,P＞0.05).The SDD measurements in the three groups were(1.9±0.3)mm,(3.6±0.8)mm,(5.5±0.7)mm,respectively.Statistical analysis using LSD-t test revealed significant differences between the three groups(t=5.521,P＜0.05;t=6.142,P＜0.05;t=25.828,P＜0.05).The sensitivity,specificity,positive predictive value,and negative predictive value for detecting annular pancreas at a cutoff of 2.3 mm were determined to be 96.4%,100%,100%,and 96.6%,respectively,with an area under the receiver operating charac-teristic curve of 0.999.Conclusion SDD could be employed for the diagnosis of neonatal annular pancreas.

Renal cell carcinoma is a common malignant tumor in urinary system with poor prognosis, and the advanced patients are prone to distant metastases such as bone, brain and lung. Common treatment modalities for renal cell carcinoma include surgery, radiotherapy, immunotherapy and targeted therapy. Tumor microenvironment plays an important role in the occurrence, pathophysiological process and treatment of renal cell carcinoma. The study of tumor microenvironment characteristics has led to significant advances in the treatment of renal cell carcinoma. At present, immunotherapy and cell therapy for renal cancer can effectively prolong the survival of patients and provide new treatment methods for patients with advanced renal cell carcinoma.

Objective To investigate the relationship between serum levels of microRNA-130a(miR-130a),angiotensin Ⅱ(AngⅡ)and the degree of coronary artery lesions in patients with acute coronary syn-drome(ACS).Methods A total of 160 ACS patients admitted to the hospital from January 2021 to February 2023 were selected as the ACS group.According to total Gensini score,ACS patients were divided into mild group(57 cases),moderate group(54 cases)and severe group(49 cases).At the same time,160 healthy peo-ple were selected as the control group.The clinical data of all subjects were collected.The serum levels of miR-130a and AngⅡ were detected by real-time fluorescence quantitative PCR and enzyme-linked immunosor-bent assay,respectively.The clinical data and serum levels of miR-130a and AngⅡ were compared between control group and ACS group.The serum levels of miR-130a and AngⅡ were compared between ACS patients with different degrees of disease.Pearson correlation analysis was used to analyze the correlation between ser-um miR-130a level and AngⅡ in ACS patients.Multivariate Logistic regression was used to analyze the risk factors of ACS.Receiver operating characteristic curve was used to analyze the diagnostic value of serum miR-130a and AngⅡ levels for moderate and severe ACS.Results Compared with the control group,the ACS group had significantly higher proportions of patients with a history of hypertension and diabetes and signifi-cantly higher serum levels of miR-130a and AngⅡ(P<0.05).The serum levels of miR-130a and AngⅡ were increased sequentially in the mild group,moderate group and severe group(P<0.05).Serum miR-130a level was positively correlated with AngⅡ level in ACS patients(P<0.05).Hypertension,diabetes history and ele-vated serum levels of miR-130a and AngⅡ were independent risk factors for ACS(P<0.05).The area under the curve(AUC)of serum miR-130a,AngⅡ and their combination in the diagnosis of moderate ACS were 0.728,0.823 and 0.885,respectively,and the AUC of the combination of miR-130a and AngⅡ was higher than that of miR-130a,AngⅡ(P<0.05).The AUC of serum miR-130a,AngⅡ and their combination in the diagnosis of severe ACS were 0.731,0.730 and 0.825,respectively.The AUC of the combination of miR-130a and AngⅡ was higher than that of miR-130a and AngⅡ(P<0.05).Conclusion ACS patients serum miR-130-a,AngⅡ level is higher,and the serum miR-130a,AngⅡ levels are associated with the ACS degree of cor-onary artery lesions,the combination of the both degree of coronary artery lesions with high diagnostic value.

Objective:To investigate the incidence of liver injury in patients with coronavirus disease 2019 (COVID-19), and to explore its impact on the condition and prognosis of patients.Methods:The medical records of 67 patients with COVID-19 who presented with pneumonia hospitalized at Tongji Hospital, Huazhong University of Science and Technology from February 11 to March 28, 2020 were collected. The results of liver biochemistry and coagulation function test at admission were analyzed. Data were compared by chi-square test, analysis of variance or Kruskal-Wallis H test. Results:Among 67 patients, total bilirubin increased in seven (10.4%) patients, which was slightly abnormal, albumin decreased in 36(53.7%) cases, and was below 30 g/L in 15(22.4%) cases, alanine transaminase (ALT) and aspartate transaminase (AST) were elevated in 19(28.4%) and 12(17.9%) cases, respectively. A total of 22(32.8%) cases had elevated ALT and (or) AST. The incidences with elevated ALT and (or) AST in moderate and severe patients were 33.3%(10/30) and 26.9%(7/26), respectively. Five of 11 critical patients had elevated ALT and (or) AST. There was no significant difference among the three groups ( χ2=1.21, P=0.546). Abnormal alkaline phosphatase and (or) γ-glutamyl transpeptidase were observed in 11(16.4%) cases. The prolongation of prothrombin time (PT) and activated partial thromboplastin time (APTT) occurred in 10(14.9%) and 17(25.4%) patients, respectively, while most of them were slightly abnormal. Only one patient presented with prolongation of PT and APTT meeting the standard of liver failure. A total of 61.2%(41/67) and 65.7%(44/67) of cases showed increase of fibrinogen and D-dimer, respectively, and 28.4%(19/67) and 19.4%(13/67), respectively increased to an obvious extent. The albumin levels in moderate, severe and critical patients were (37.85±6.19) g/L, (32.96±4.33) g/L and (33.02±3.63) g/L, respectively, which were significantly different ( F=7.36, P=0.001). There were significant differences in PT, APTT, fibrinogen and D-dimer among the three groups ( F=3.22, 3.31, 4.06 and H=17.63, respectively, all P<0.05). Conclusions:COVID-19 only leads to mild liver injury and has only mild impact on liver function. The decrease of albumin level and the increase of fibrinogen and D-dimer may be early predicting indexes for the disease severity.

Objective: To explore the emotional and behavioral problems of different only child and multiple child families, and to provide a reference for developing effective parenting styles. Methods: A stratified random cluster sampling method was adopted to investigate 2 647 guardians of preschool children in Tongling City from April to June, 2022. Children s emotional and behavioral problems were evaluated by using the self designed parenting questionnaire and the Children s Strengths and Difficulties Questionnaire (SDQ) parent edition. Results: The abnormal total score detection rate of emotional and behavioral problems of preschool children was 15.5%, and the rate of abnormal peer interaction was the highest (19.5%). In multiple child families, the first born child (17.5%, 20.4%), compared with the second and third child (11.5%, 9.5%), was more likely to exhibit conduct and hyperactivity problems ( χ 2=8.44, 29.75, P <0.01). There were differences in parenting attitudes between only child and multiple child families( χ 2=9.38, P <0.05). The results of the Logistic regression analysis showed that more frequent parent child discussion, the persuasive education and consistent family discipline strategy were negatively related to the emotional and behavioral problems of only children and children in multiple child families ( OR =0.15, 0.49, 0.38; 0.34, 0.40, 0.42, P <0.05). However, harmonious family relationships were only negatively related to emotional and behavioral problems in only children ( OR =0.08, P <0.01), and a higher education level among mothers was negatively related to emotional and behavioral problems in children from multiple child family environments( OR=0.30, 0.45, P <0.05). Conclusion The emotional and behavioral problems are serious of preschool children in Tongling City, the psychological development of the oldest children from multiple child and only child families should be actively followed, as this would help to promote a better understanding of the development of preschool children s physical and mental health.

Objective: To examine the eating behaviors and associated factors among preschool children from multiple child families, so as to provide a basis for promoting healthy eating habits in this population. Methods: From April to June 2022, a stratified random cluster sampling method was employed to selected 2 647 guardians of preschool children in 11 kindergartens in Tongling City. Parenting style questionnaire, Identification and Management of Feeding Difficulty Questionnaire (IMFeD), Caregiver s Feeding Style Questionnaire (CFSQ) and a self designed questionnaire were administered. Multiple linear regression was performed to analyze the factors influencing eating behaviors among preschool children. Results: In the study, the detection of eating behavior problems among preschool children was 71.4%, and the detection of reduced appetite was the highest (55.6%). The detection rates of anorexia, picky eating, poor eating and improper eating behavior in only child families were higher (60.6%, 41.0%, 32.0%, 19.5%), compared with those in multiple child families (51.7%, 36.4%, 27.2%, 16.6%) ( χ 2=20.05, 5.95, 7.16, 3.92, P < 0.05 ). Among multiple child families, the detection rates of fear of eating and underlying disease were the lowest in 5-<10-year-old group (2.3%, 0.6%) ( χ 2=11.54, 8.51, P <0.05). In multiple child families, the detection rates of picky eating and poor eating habits for the first-born child were higher (42.0%, 32.5%), compared with second born and third born child (34.6%, 25.6%)( χ 2= 6.15, 6.38, P <0.05). The results of multiple linear regression analysis showed that multiplechild families ( β =-1.40), democratic parenting style ( β =-0.07), higher feeding response scores ( β =-0.33) were negatively associated with eating behavior problems among preschool children ( P <0.05). Eating behavior problems among preschool children were positively correlated with less educated mothers [high and junior high school education ( β =0.87), primary school education and below ( β =3.69)], longer average daily screen time ( β =0.10), higher feeding requirements scores ( β =0.64), doting parenting styles ( β =0.21), permissive parenting styles ( β =0.27) and inconsistent parenting styles ( β =0.14)( P <0.05). Conclusion The detection rate of the eating behaviors problems among preschool children is high in schools. Greater attention should be paid to only child and first born child of multiple child families, and appropriate feeding and parenting styles, so as to promote healthy eating habits among this population.

Objective:To explore the temporal and spatial distribution characteristics of reported incidence of schizophrenia in Ningbo from 2018 to 2022 and to provide a scientific basis for rational allocation of mental health resources and comprehensive prevention and treatment of schizophrenia.Methods:The reported incidence data of schizophrenia from 2018 to 2022 were collected from Ningbo's mental health information management system, and the reported incidence was calculated by township. The spatial correlation analysis and the spatiotemporal scan analysis were used to study the spatiotemporal distribution of schizophrenia.Results:The reported incidence of schizophrenia decreased from 2018 to 2022, with 4 133 new cases reported, and the annual average reported incidence was 9.76/100 000. Global and local spatial autocorrelation analysis showed positive spatial correlations and hot spots in 2018-2020. The space-time scan analysis showed an incidence cluster in Dongqiao Town, Haishu District, during 2018-2019. The RR was 2.46, and the log-likelihood ratio was 256.89. Conclusions:The reported incidence of schizophrenia in Ningbo has obvious temporal and spatial aggregation, and the high incidence area explored can provide clues for further research on the correlation between environmental factors and the incidence of schizophrenia and has certain guiding significance for the rational allocation of mental health resources in Ningbo.

The retrieval period was from the establishment of the database to June 4, 2022.Results:A total of 30 articles were included, including one guideline, one evidence summary, one clinical decision-making, two expert consensuses, and 25 systematic reviews. 22 pieces of evidence from 12 aspects were summarized, including applicable population, exercise benefit, exercise risk, exercise assessment, exercise program, exercise method, exercise time, exercise intensity, exercise monitoring, formulation principles, management mode, and health education were summarized.Conclusions:The evidence summary process is scientific, rigorous, and comprehensive in content. In the process of evidence transformation, medical and nursing staff should select the best evidence according to specific situations and individual patient factors, so as to guide patients with rotator cuff injury to exercise safely and effectively after surgery to improve clinical outcomes.

Objective:To explore and analyze the relationship between serum KLK11 and MK levels and the effect of first iodine 131 ( 131I) ablation after operation for differentiated thyroid cancer. Method:108 patients with differentiated thyroid cancer who underwent total thyroidectomy in our hospital from Jun. 2020 to Jun. 2021 were consecutively selected, and received radioactive ablation after surgery. There were 37 males and 71 females. The age was (48.32±4.25) years, ranging from 28 to 79 years. The patients were divided into successful ablation according to whether the ablation was successful after treatment. There were 64 cases in the group and 44 cases in the unsuccessful group, and 60 healthy people with no abnormality in physical examination during the same period were selected as the control group. The patients were divided into a metastasis-positive group of 20 cases and a metastasis-negative group of 88 cases according to whether lymph nodes occurred. After surgery, serum samples of all subjects were taken, and enzyme-linked immunosorbent assay was used to detect the levels of serum kallikrein-related peptidases 11 (KLK11) and midkine (MK) , and the levels of serum KLK11 and MK were analyzed. Gender, age, BMI, TNM stage, TSH, maximum diameter of lesion, and duration of nail removal were collected. Univariate analysis and logistic regression analysis were used to analyze the independent risk factors of postoperative efficacy.Result:The levels of serum KLK11 and MK in the successful and unsuccessful groups were higher than those in the control group, while the levels of KLK11 and MK in the unsuccessful group were higher than those in the successful group (KLK11: t= 2.642, P<0.05; MK: t=11.906, P<0.05) . The serum levels of KLK11 and MK in the metastasis-positive group were higher than those in the metastasis-negative group (KLK11: t= 2.908, P<0.05; MK: t=14.907, P<0.05) . Univariate analysis showed that BMI ( χ2=6.780, P=0.009) , maximum diameter of lesions ( χ2=14.819, P=0.001) , TSH ( χ2=13.627, P=0.001) , serum KLK11 ( t=2.642, P=0.01) , and serum MK ( t=11.906, P<0.001) were associated with the effect of first 131I ablation after surgery for differentiated thyroid cancer ( P<0.05) . Taking the success of ablation as the dependent variable, a multivariate logistic regression analysis was performed. The results showed that the maximum diameter of the lesions greater than 2 cm ( OR=10.740, 95%CI: 7.033-16.401) , increased level of TSH ( OR=8.559, 95%CI: 2.812-26.057) , increased serum KLK11 level ( OR=16.710, 95%CI: .548-32.666) and increased serum MK level ( OR=10.580, 95%CI: 6.294-17.786) were the factors affecting the first 131I ablation effect after DTC surgery ( P<0.05) . Conclusion:The elevated levels of serum KLK11 and MK are independent risk factors affecting the efficacy of the first 131I ablation after surgery for differentiated thyroid cancer.
