Objective:To analyze the epidemiological and clinical characteristics of hospitalized patients with dengue fever in Guangdong Province in 2019, so as to provide reference for clinical diagnosis and treatment of dengue fever.Methods:The general data, laboratory examination data, clinical manifestations and prognosis data of 480 inpatients with dengue fever admitted to Eight People′s Hospital Affiliated to Guangzhou Medical University between January 4 and October 31, 2019 were analyzed retrospectively. The clinical and onset characteristics of patients with dengue fever were described.Results:Among 480 dengue patients, 442(92.1%) were dengue fever, 38(7.9%) were severe dengue, and 136(28.3%) had underlying diseases. The peak age of onset was mainly in young adults aged 20 to 49 years old, accounting for 66.0%(317/480) in total. The seasonal peak was mainly in August to October. There were 399(83.1%) local cases and 61(12.7%) imported cases. The most common clinical manifestations were fever (98.1%, 471/480), chills (72.9%, 350/480), headache (58.5%, 281/480) and bone/joint/muscle pain (67.1%, 322/480), followed by digestive tract symptoms and respiratory tract symptoms. Among 446 serum samples, 358 (80.3%) were dengue virus (DENV)-1, 54 (12.1%) were DENV-2, 34 (7.6%) were DENV-3. The main laboratory tests of the patients were leucopenia (65.8%, 316/480), low hematocrit (30.2%, 145/480), thrombocytopenia (48.3%, 232/480), neutropenia (44.8%, 215/480), elevated alanine aminotransferase (ALT) (37.7%, 181/480) and aspartate aminotransferase (AST) (59.4%, 285/480). Treatment mainly adopted symptomatic support treatment and active prevention of complications. The length of stay was (5.8±3.1) days (range 1.0-38.0 days). A total of 461(96.0%) patients were cured or improved.Conclusions:In 2019, the majority of dengue fever patients in Guangdong Province are young adults aged 20 to 49 years old, and the proportion of severe patients is high, with DENV-1 infection as the main type. After symptomatic support treatment and active prevention of complications, most of the dengue fever patients have a good prognosis.

Objective To design and construct a syndrome differentiation knowledge graph that integrates TCM facial color diagnosis information;To explore the hidden relationships between the knowledge.Methods The literature data came from ancient classics,textbooks,as well as standard literature related to inspection included in the CNKI,VIP and Wanfang Data from the establishment of the databases to December 31,2022.The clinical data was sourced from 30 elderly individuals who underwent TCM health examinations at the Community Health Service Center in Jiading Industrial Zone,Shanghai in September 2022.Facial image acquisition was performed using TFDA-1 digital tongue and facial diagnostic instrument.By following the steps of knowledge extraction,knowledge fusion and quality assessment to construct a graph,and with the assistance of TCM experts for interpretation,using Access 2019 to integrate qualitative textual data and quantitative objective image digital information,a syndrome differentiation knowledge graph integrating TCM facial diagnosis was designed and completed in the Neo4j graph database.In addition,a method was designed to shift facial diagnosis knowledge from qualitative to quantitative.Results There were a total of 194 nodes under 8 entity term types and 12 entity term labels,as well as 361 relationships under 13 semantic relationships in knowledge graph.The Neo4j graph database provided a visualized TCM facial color diagnosis and differentiation,which could be queried and fed back using Cypher language.Conclusion The knowledge graph constructed based on the theory of TCM facial color diagnosis visually shows the complex correlation between facial color diagnosis and syndrome differentiation diagnosis,with a knowledge representation model that forms qualitative data of image features → semantic relationships → syndrome differentiation diagnosis forms.

Objective:To explore the risk of hip fracture, changes of composite indices of femoral neck strength and its influential factors in non-low-weight postmenopausal women with type 2 diabetes mellitus(T2DM).Methods:A total of 626 non-low-weight postmenopausal women were selected and divided into type 2 diabetes group, pre-diabetic group, and non-diabetic group according to the diagnostic criteria of the American Diabetes Association in 2010. Each participant completed the questionnaire, physical examination, laboratory examination, and Dual-energy X-ray absorptiometry(DXA) examination.Results:Hip fracture rate in T2DM group was significantly higher than that in non-diabetic group(3.4% vs 0.7%, P<0.05), while no significant difference was observed between pre-diabetic group and non-diabetic group(1.1% vs 0.7%, P>0.05). Bone mineral density(BMD) of lumbar spine 1-4, femoral neck, and total hip was comparable between T2DM group and non-diabetic group or pre-diabetic group and non-diabetic group, respectively( P>0.05). The composite indices of femoral neck strength in T2DM group was significantly lower than that in non-diabetic group( P<0.05), but there was no significant difference between pre-diabetic group and non-diabetic group( P>0.05). Regression analysis showed that age and body mass index were the main influential factors of the femoral neck bone mineral density and the composite indices of femoral neck strength( P<0.05). Conclusion:The composite indices of femoral neck strength could be used as one of the markers to evaluate the risk of hip fracture in type 2 diabetic patients.

Objective:To explore the changes of bone turnover markers and geometric parameters of hip bone in overweight postmenopausal women with metabolic syndrome(MS), as well as the influence of MS components. To analyze the association of these factors with the risk of fracture.Methods:A total of 505 overweight postmenopausal female patients who underwent health check-up in Lianhu Community Service Center, Danyang City, Jiangsu Province from January to December 2017 were selected. According to the MS diagnostic criteria of the International Diabetes Federation(2009), the patients were divided into MS group( n=331)and non-MS group( n=174). Blood samples were collected to determine the level of procollagen type 1 N-terminal propeptide(P1NP)and carboxy-terminal cross-linked telopeptide of type 1 collagen(CTX). Bone mineral density and hip bone geometry parameters were tested with dual-energy X-ray absorptiometry and hip structural analysis software. Results:The incidence of osteoporotic fracture and hip fracture in MS group was significantly higher than that in non-MS group(21.1% vs 13.8%, 4.8% vs 1. 1%, P<0.05). However, the bone mineral density of lumbar vertebra 1-4, femoral neck, and total hip in MS group was significantly higher than that in non-MS group, which remained after adjusting for age( P<0.05), but the difference disappeared after further adjustment for body mass index( P>0.05). The P1NP, CTX, femur strength index(FSI), section modulus(SM), and cross-sectional area(CSA)of MS group were significantly lower than those of non-MS group, the buckling ration(BR)was significantly higher than that in non-MS group, and the differences were still statistically significant after adjusting for age and body mass index( P<0.05). There was no significant difference in bone mineral density of lumbar vertebra 1-4, femoral neck, total hip, P1NP, and CTX between fracture group and non-fracture group in patients with MS. But FSI, SM, cross-sectional moment of inertia(CSMI), and CSA were significantly lower, BR was significantly higher( P<0.05) and femur strength decreased in patients with fracture. Regression analysis showed that high BR was an independent risk factor for fracture risk, while high FSI, SM, CSMI, and CSA were protective factors. Multivariate linear regression analysis showed that wasit circumference, diastolic blood pressure, and fasting plasma glucose were the main MS components affecting bone mineral density, bone turnover indexes, and hip bone geometry parameters. Conclusions:Overweight postmenopausal MS patients had decreased bone turnover rate, femoral strength, and relatively poor bone quality. Hip bone geometry parameters can be used as one of the methods to assess fracture risk in MS patients. Waist circumference, diastolic blood pressure, and fasting blood glucose are the important MS components affecting bone mass and bone quality.

Objective:To investigate the correlation between fat distribution and the composite indices of femoral neck strength in obese postmenopausal women.Methods:A total of 293 postmenopausal women with non-low body weight were selected, laboratory tests, body composition analyzer test and double-energy X-ray absorptiometry scan were performed. Based on the body mass index(BMI), they were divided into three groups, the normal BMI group(18.5 kg/m 2≤BMI<24.0 kg/m 2, n=91), the overweight group(24.0 kg/m 2≤BMI<28.0 kg/m 2, n=115), and the obese group(BMI≥28.0 kg/m 2, n=87). The measurement results were analyzed. Results:In the obese group, bone mineral density(BMD) of all sites was higher than that in the normal BMI group and overweight group( P<0.005), compression strength index(CSI), bending strength index(BSI), and impact strength index(ISI) were significantly lower than those in the normal BMI group( P<0.001, P=0.008, P=0.001). In the obese group, waist circumference, waist-hip ratio, total fat mass, appendicular fat mass, and trunk fat mass were risk factors for CSI, BSI and ISI independent of age, fasting blood glucose, and BMI( P<0.05). Visceral fat grade and Chinese visceral adiposity fat index were the risk factors for CSI, BSI, and ISI( P<0.05). Conclusion:The composite indices of femoral neck strength decreased in obese postmenopausal women, and both subcutaneous fat and visceral fat were negatively associated with the composite indices of femoral neck strength.

Attention deficit hyperactivity disorder is a common neurodevelopmental disorder characterized by persistent attention deficit, hyperactivity, and impulsive behaviors that are not consistent with developmental age.Academic and vocational difficulties, social exclusion, and delinquent behaviors are manifested in daily life.It is also commonly accompanied by psychiatric problems.At the same time, mental problems are common, and the overall quality of life is greatly affected, placing a heavy burden on society as well as the family.International attention deficit hyperactivity disorder experts have developed a common and comprehensive International Classification of Functioning, Disability and Health core set of classifications for assessing individual functioning in attention deficit hyperactivity disorder.
