ABSTRACT
@#Cardiovascular diseases is the leading cause of threat to human life and health worldwide. Early risk assessment, timely diagnosis, and prognosis evaluation are critical to the treatment of cardiovascular diseases. Currently, the evaluation of diagnosis and prognosis of cardiovascular diseases mainly relies on imaging examinations such as coronary CT and coronary angiography, which are expensive, time-consuming, partly invasive, and require high professional competence of the operator, making it difficult to promote in the community or in areas where medical resources are scarce. The fundus microcirculation is a part of the human microcirculation and has similar embryological origins and physiopathological features to cardiovascular circulation. Several studies have revealed fundus imaging biomarkers associated with cardiovascular diseases, and developed and validated intelligent diagnosis and treatment models for cardiovascular diseases based on fundus imaging data. Fundus imaging is expected to be an important adjunct to cardiovascular disease diagnosis and treatment given its noninvasive and convenient nature. The purpose of this review is to summarize the current research status, challenges, and future prospects of the application of artificial intelligence based on multimodal fundus imaging data in cardiovascular disease diagnosis and treatment.
ABSTRACT
Objective:To explore the establishment of a surgical complication monitoring mode based on data on the medical record homepage, and analyze its impact on the trend of changes in surgical complication incidence.Methods:A monitoring mode of surgical complication was developed based on the " structure-process-results" framework by using surgical complication rates derived from performance appraisal for a tertiary general hospital in Guangzhou. The number of surgical complications and the number of discharged surgical patients was collected from the hospital from January 2019 to June 2022 through the home page collection system for performance appraisal of national tertiary public hospitals. Descriptive analysis was used to analyze the incidence of surgical complications, and Joinpoint regression was used to analyze the trend of changes in the incidence of surgical complications. Monthly percentage change ( MPC) and average monthly percentage change ( AMPC) were calculated. Results:Since the hospital began implementing the surgical complication monitoring mode in May 2021, the incidence of surgical complications had decreased from 2.55% in June 2021 to 0.82% in June 2022, with an MPC of -5.58% ( P=0.024), which was better than the changes from January 2019 to May 2021 ( MPC=0.18%, P=0.755). Conclusions:The surgical complication monitoring mode constructed by the hospital can effectively reduce the incidence of surgical complications, providing reference for optimizing hospital′s medical quality management process and decision-making mode.
ABSTRACT
The clinical data of rare hemiaxial limb skeletal Ollier disease in a child admitted to the Affiliated Hospital of Zunyi Medical University in July 2020 were analyzed retrospectively.The literature was reviewed and the methods of diagnosis and treatment of Ollier disease in children were summarized.The patient is a 3-year-old boy, who was hospitalized for 2 days of claudication of the right lower limb.Imaging examination showed hemiaxial limb ske-letal disease and suggested the possibility of histiocytosis.Curettage, bone graft and plaster external fixation were performed on the lesions of the right femoral neck and greater trochanter.The postoperative pathological results indicated endogenous chondroma.The follow-up results revealed that the bone graft healed well, the symptoms of claudication were improved, and there were no complications such as infections and femoral head necrosis.Long tubular bones are the main site of children′s Ollier disease, but multiple lesions in hemiaxial limbs are extremely rare.It is difficult to diagnose this rare case, which is easily misdiagnosed.At present, it′s diagnosis still needs to be confirmed by pathological examination.Surgical treatment and long-term follow-up are needed for children with a wide range of lesions, seriously impaired limb function and obvious limb deformity.
ABSTRACT
Objective:To analyze the characteristics of aneurysmal bone cysts (ABC) and related factors of postoperative recurrence, so as to improve the clinical diagnosis and treatment level of ABC in children.Methods:The clinical data of children pathologically diagnosed as ABC after surgery in the Affiliated Hospital of Zunyi Medical University from January 2010 to December 2018 were retrospectively analyzed.Clinical characteristics of the patients, including age, gender, lesion sites, and main clinical manifestations (pain, swelling, local tenderness, joint dysfunction and pathological fracture) were analyzed and summarized.Before operation, imaging Enneking staging was carried out, cyst volume was estimated, and the distance from cysts to the epiphyseal plate was measured.During surgery, patients received lesion curettage, local cautery and bone grafting, and the pathological fractures were treated with auxiliary internal fixation.Results were determined by Neer imaging grading after surgery, and grades Ⅰ and Ⅱ were postoperative recurrence.Possible recurrence factors were analyzed statistically by Fisher′ s exact test. Results:A total of 29 cases meeting the criteria were included, including 19 males and 10 females.The age ranged from 3.6 to 14.0 years old, averaging 9.2 years old; 12 patients were smaller than 10 years old and 17 patients were older than 10 years old.The cysts of 9 cases were located in proximal femur (31.0%), 5 cases in proximal humerus (17.2%), and 4 cases in proximal fibula (13.8%); The other 11 cases (37.9%) occurred in the middle and distal end; 26 cases (89.7%) had local tenderness, 25 cases (86.2%) showed varying degrees of pain, 18 cases (62.1%) presented local swelling, 15 cases (51.7%) were accompanied by joint dysfunction, and 12 cases (41.4%) were combined with pathological fractures.According to Enneking staging results, 18 cases (62.1%) were at rest stage, 7 cases (24.1%) at active stage, and 4 cases (13.8%) at invasive stage.Cyst volume was estimated to be 3.3-172.0 cm 3, with a median of about 50.8 cm 3.The distance from cysts to the epiphyseal plate was 0-85.0 mm, with a median of 20.8 mm.All children were followed up for 2.2-10.1 years (averaging 3.8 years). There were 6 cases (20.7%) of grades Ⅰ and Ⅱ according to Neer grading standard, and they suffered from recurrence about 2.5-20.3 months after surgery (averaging 12.5 months). The recurrence rate was higher in patients with cyst volume >50.8 cm 3 (42.9%, 6/14 cases) as well as in patients at active stage and invasive stage (45.5%, 5/11 cases) ( P<0.05). There was no statistical difference between the recurrence rate of ABC in different gender, age, the distance from cysts to the epiphyseal plate and pathological fractures. Conclusions:ABC is prone to occur in the proximal metaphysis of the long bones of children′s extremities.Main manifestations are pain, swelling, local tenderness and joint dysfunction, and ABC is frequently accompanied by pathological fractures.A higher postoperative recurrence rate is related to a larger cyst size and the active and invasion phases of the cyst, but gender, age, the distance from the cyst to the epiphyseal plate and pathological fractures are not significantly related to the postoperative recurrence rate.
ABSTRACT
With the reform of medical insurance payment mode and the promotion of medical insurance policy, medical insurance management has become the core of public hospital operation and management. According to the business scenario of medical insurance management in public hospitals, medical insurance intelligent management can be divided into three levels: automatic medical insurance intelligent management engine based on rules, digital medical insurance management assistance based on dialogue user interface and hospital medical insurance management brain based on deep learning. In August 2020, under the requirements of hospital intelligent management standards, a tertiary hospital broke through the traditional medical insurance management mode to launch the practice of digital enabled panoramic scene intelligent management of medical insurance, which included medical insurance intelligent business audit, medical insurance intelligent reconciliation, medical insurance intelligent cost control and medical insurance intelligent management cockpit. These measures had realized the intellectualization and standardization of medical insurance management and improved the overall operation efficiency of the hospital.
ABSTRACT
Objective:To retrospectively analyze the classification of twin reversed arterial perfusion(TRAP) by prenatal ultrasound diagnosis, and to explore the clinical significance of this classification method.Methods:One hundred and fourteen TRAP cases were selected for prenatal ultrasound examination from January 2001 to January 2020 in Maternal and Child Health Hospital of Hubei Province, and were studied following the classification: hemiacardius(type Ⅰ), anceps trunk(type Ⅱ), acephalus trunk(type Ⅲ), acephalus acormus(type Ⅳ), acardius amorphous(type Ⅴ). Natural pregnancy outcomes were analyzed between group A(type Ⅰ, type Ⅱ, type Ⅲ) and group B(type Ⅳ, type Ⅴ).Results:Among 114 cases of TRAP, 27 cases (23.7%) were live birth, 33 cases (29.0%) were intrauterine death, 7 cases (6.1%) were perinatal death, 22 cases (19.3%) were induced labor complicated with heart failure, 4 cases (3.5%) were induced labor with malformation of pump twin, 21 cases (18.4%) were induced without heart failure of pump twim. Among 114 cases of TRAP, 20 cases (17.5%) were type Ⅰ, 27 cases (23.7%) were type Ⅱ, 48 cases (42.1%) were type Ⅲ, 8 cases (7.0%) were type Ⅳ and 11 cases (9.7%) were type Ⅴ. The prognosis of group B was better than group A during natural pregnancy ( P=0.007). Conclusions:Based on the diagnosis of prenatal ultrasound, the prognosis of type Ⅳ and type Ⅴ TRAP is better than that of type Ⅰ, type Ⅱ and type Ⅲ. The classification by prenatal ultrasound has positive significance for the clinical prognosis of pump twin.
ABSTRACT
Objective:To analyze the clinical characteristics of bone tumors in children, so as to improve the understanding and diagnosis of bone tumors in children.Methods:The clinical data of bone tumors in children hospitalized in the Affiliated Hospital of Zunyi Medical University from January 2009 to December 2018 were collected, with the age ≤ 14 years old.All children′s gender, age, tumor type, location, number of lesions and first symptoms were counted, and the clinical characteristics of bone tumors in children in this area were analyzed.Results:Totally 548 children with bone tumor were collected, with 344 males and 204 females, and the ratio of males to females was 1.69∶1.00, with 462 single cases and 86 multiple cases.Among the multiple cases (86 cases), 82 cases (95.35%) were benign bone tumors.The total number of cases increased with age.The age of different tumors has its own characteristics.Tibia was the most common tumor location (223 in total), followed by femur (177 in total) and humerus (82 in total). According to the classification of tumor nature, there were 478 cases (87.22%) of benign bone tumors, 43 cases (7.85%) of intermediate bone tumors and 27 cases (4.93%) of malignant bone tumors.The incidence of benign bone tumors was significantly higher than that of intermediate and malignant bone tumors, with statistically significant differences ( χ2=72.604, P<0.05). Among the benign bone tumors (478 cases), osteochondroma was the most common (265 cases), accounting for 55.44%; among the intermediate bone tumors (43 cases), aneurysmal bone cyst was the most common (20 cases), occupying 46.51%; among the malignant bone tumors(27 cases), osteosarcoma was the most common (16 cases), accounting for 59.26%.Among the initial symptoms, 268 cases were local masses, and 166 cases were pain, which were significantly higher than that of 79 without symptoms, with 28 lameness, 4 deformity and 3 dysfunction, and the differences were statistically significant( χ2=71.422, P<0.05). Conclusions:The majority of bone tumors patients in children were male, and the incidence increased with age.Benign and solitary are common, and the multiple cases were mainly benign.The most common locations are tibia and femur.The initial symptoms were mainly local mass and pain.Most importantly, the clinical characteristics of different tumors are slightly different.
ABSTRACT
Background and Objectives@#Psoriasis is a chronic inflammatory skin disease, which the mechanisms behind its initiation and development are related to many factors. DMSCs (dermal mesenchymal stem cells) represent an important member of the skin microenvironment and play an important role in the surrounding environment and in neighbouring cells, but they are also affected by the microenvironment. We studied the glucose metabolism of DMSCs in psoriasis patients and a control group to reveal the relationship among glucose metabolism, cell proliferation activity，and VEC (vascular endothelial cell) differentiation in vitro, we demonstrated the biological activity and molecular mechanisms of DMSCs in psoriasis. @*Methods@#and Results: We found that the OCR of DMSCs in psoriatic lesions was higher than that in the control group, and mRNA of GLUT1 and HK2 were up-regulated compared with the control group. The proliferative activity of DMSCs in psoriasis was reduced at an early stage, and mRNA involved in proliferation, JUNB and FOS were expressed at lower levels than those in the control group. The number of blood vessels in psoriatic lesions was significantly higher than that in the control group (p＜0.05), which the mRNA of VEC differentiation, CXCL12, CXCR7, HEYL and RGS5 tended to be increased in psoriatic lesions compared to the control group, in addition to Notch3. @*Conclusions@#We speculated that DMSCs affected local psoriatic blood vessels through glucose metabolism, and the differentiation of VECs, which resulted in the pathophysiological process of psoriasis.
ABSTRACT
The ticks feed large amount of blood from their hosts and transmit pathogens to the victims. The salivary gland plays an important role in the blood feeding. When the female ticks are near engorgement, the salivary gland gradually loses its functions and begins to rapidly degenerate. In this study, data-independent acquisition quantitative proteomics was used to study changes in the phosphorylation modification of proteins during salivary gland degeneration in Haemaphysalis longicornis. In this quantitative study, 400 phosphorylated proteins and 850 phosphorylation modification sites were identified. Trough RNA interference experiments, we found that among the proteins with changes in phosphorylation, apoptosis-promoting Hippo protein played a role in salivary gland degeneration.
ABSTRACT
PURPOSE: Details of patients hospitalized for asthma exacerbation in mainland China are lacking. To improve disease control and reduce economic burden, a large sample survey among this patient population is indispensable. This study aimed to investigate the clinical characteristics and outcomes of such patients.METHODS: A retrospective study was conducted on patients hospitalized for asthma exacerbation in 29 hospitals of 29 regions in mainland China during the period 2013 to 2014. Demographic features, pre-admission conditions, exacerbation details, and outcomes were summarized. Risk factors for exacerbation severity were analyzed.RESULTS: There were 3,240 asthmatic patients included in this study (57.7% females, 42.3% males). Only 28.0% used daily controller medications; 1,287 (39.7%) patients were not currently on inhaled corticosteroids. Acute upper airway infection was the most common trigger of exacerbation (42.3%). Patients with severe to life-threatening exacerbation tended to have a longer disease course, a smoking history, and had comorbidities such as hypertension, chronic obstructive pulmonary disease (COPD), and food allergy. The multivariate analysis showed that smoking history, comorbidities of hypertension, COPD, and food allergy were independent risk factors for more severe exacerbation. The number of patients hospitalized for asthma exacerbation varied with seasons, peaking in March and September. Eight patients died during the study period (mortality 0.25%).CONCLUSIONS: Despite enhanced education on asthma self-management in China during recent years, few patients were using daily controller medications before the onset of their exacerbation, indicating that more educational efforts and considerations are needed. The findings of this study may improve our understanding of hospital admission for asthma exacerbation in mainland China and provide evidence for decision-making.

Objective:To investigate the diagnostic value and cutoff value of the basal luteinizing hormone (LH) level for central precocious puberty (CPP) in girls with different body mass index (BMI) values.Methods:A total of 1 087 girls aged 6 to 8 years old with breast development and visiting the Department of Endocrine Genetics and Metabolism, Fuzhou Children′s Hospital of Fujian Medical University from January 2014 to December 2018 were enrolled.The girls had the breast development of Tanner stage B2 or B3.They were divided into groups of normal weight (840 cases), overweight (133 cases) and obesity (114 cases) according to BMI percentiles corresponding to their age and sex.All individuals underwent gonadotropin-releasing hormone (GnRH) agonist test.Statistical analysis was performed using SPSS 18.0 software, and the receiver operating characteristic (ROC) curve was drawn.Results:In the normal weight group, 393 girls were positive and 447 girls were negative for GnRH test.In the overweight group, 72 girls were positive and 61 girls were negative for GnRH test.In the obesity group, 40 girls were positive and 74 girls were negative for GnRH test.The areas under the ROC curve (AUC) of the basal LH level for the diagnosis of CPP in the normal weight, overweight, and obese girls were 0.826, 0.774, and 0.801, respectively.When the Youden index was maximum, the cutoff values of the basal LH level were 0.245 IU/L, 0.225 IU/L and 0.145 IU/L, respectively; the sensitivities were 63.9%, 65.3%, and 80.0%, respectively; the specificities were 87.9%, 82.0%, and 71.6%, respectively.When the cutoff value of the basal LH level was 0.455 IU/L in the normal weight group, 0.480 IU/L in the overweight group, and 0.335 IU/L in the obesity group, the specificities of the 3 groups were all above 96.6%.Conclusions:It is reliable to use the basal LH level for CPP diagnosis for girls with different BMI values.The cutoff value of the basal LH level for CPP diagnosis in obese girls is the lowest.
ABSTRACT
Objective:To explore the clinical characteristics of lung adenocarcinoma patients with exon 21 L858R deletion mutation.Methods:The data of 112 patients who were diagnosed with lung adenocarcinoma and positive genetic mutations in the People's Hospital of Xinjiang Uygur Autonomous Region from January 2015 to December 2018 was retrospectively analyzed, and the patients were divided into the exon 21 L858R deletion mutation group (52 cases) and the non-exon 21 L858R deletion mutation group (60 cases). The clinical characteristics, imaging characteristics, expressions of tumor markers and smoking history of patients were compared between the two groups.Results:There was no statistical difference in the gender, age and ethnicity between the exon 21 L858R deletion mutation group and the non-exon 21 L858R deletion mutation group (P values were 0.488, 0.238 and 0.191). There was no statistical difference in the imaging features (including primary tumor site, lobulation, burr, pleural depression and small vacuoles) between the two groups (all P > 0.05). There was no statistical difference in the expressions of tumor markers (including carcinoembryonic antigen, squamous cell carcinoma antigen, neuron-specific enolase, cytokeratin 19 fragment, and gastrin-releasing peptide precursor) between the two groups (all P > 0.05). There were 20 patients (38.5%, 20/52) with smoking history in the exon 21 L858R deletion mutation group, and 4 patients (6.7%, 4/60) with smoking history in the non-exon 21 L858R deletion mutation group, the difference between the two groups was statistically significant (χ 2 = 4.182, P = 0.041). Conclusions:There is no significant difference in clinical characteristics, imaging features and expressions of tumor markers between the patients with exon 21 L858R deletion mutation and the patients without exon 21 L858R deletion mutation. Smoking may be the influencing factor of exon 21 L858R deletion mutation.
ABSTRACT
Objective To observe the incidence,clinical characteristics,related factors,adverse events during hospitalization and short-term prognosis of postprandial hypotension (PPH) in elderly patients with coronary heart disease.Methods One hundred and sixty-eight elderly patients with coronary heart disease hospitalized in the Department of Cardiology,Second Hospital of Hebei Medical University from January 2014 to January 2015 were selected as the research subjects.They were monitored by 24 h ambulatory blood pressure monitoring.According to the diagnostic criteria of PPH,they were divided into postprandial hypotension group (PPH group) 34 cases and non-postprandial hypotension group (NPPH group) 134 cases.The clinical characteristics,risk factors related to PPH,occurrence of adverse events and prognosis of all-cause death,cardiovascular and cerebrovascular adverse events were compared between the two groups.Results Among 168 elderly patients with coronary heart disease,thirty-four patients had PPH,and the incidence rate was 20.2％ (34/168).The average systolic blood pressure before meals in PPH group was (139.8± 18.6) mmHg (1 mmHg =0.133 kPa).The proportion of taking calcium antagonists was 50.0％ (17/34) higher than that in NPPH group (127.4± 13.2) mmHg,27.6％ (37/134).The difference between the two groups was statistically significant (t =6.463,x2=6.232,P＜ 0.05).PPH was higher in breakfast and dinner than in lunch;the higher the basal systolic blood pressure level,the higher the incidence of PPH.Logistic regression analysis showed that the basal systolic blood pressure level and age were positively correlated with the occurrence of PPH (r =0.301,r =0.208,P＜ 0.05).Follow-up for 26 months showed that the incidence of all-cause death and cerebrovascular events in PPH group was higher than that in NPPH group (x2 =5.800,11.560,P＜ 0.05).Conclusion The incidence of PPH in elderly patients with coronary heart disease during hospitalization is 20.2％.Breakfast and dinner at three meals are prone to PPH.Older age and high systolic blood pressure level will increase the incidence of PPH.PPH will increase the incidence of mid-term all-cause death and cerebrovascular events.

ABSTRACT
Obturator hernia is an extremely rare pelvic hernia which occurs mostly in elderly, thin, multiparous women. Clinical manifestations are abdominal pain and/or unexplained intestinal obstruction, and obturator neuralgia due to compressed obturator nerve. As the lack of specific symptoms and external masses likes other abdominal wall hernias, its diagnosis may be arduous and difficult; hence, an accurate preoperative diagnosis or surgical treatment is often delayed, such a delay often leads to gangrenous bowel in a large proportion of cases and results in unacceptably high morbidity and mortality. preoperative detection of the obturator hernia due to clinical alert and in-time computed tomography of the pelvis. Early diagnosis and prompt initiation of surgical intervention are essential for this rare entity. This explanatory review emphasizes and illuminates its various facets under the significant events, anatomy, epidemiology and rationale of its diagnosis and management to familiarize surgeons with the condition that seldom thought of and hence seldom sought.

ABSTRACT
Objective@#To explore the association of social bonds, deviant behaviors and bullying victimization among children, and to provide practical reference for deviant behavior and bullying victimization prevention among children.@*Methods@#A questionnaire survey was conducted among 1 044 students from 8 schools in Hubei Province through empirical stratification and non-strict random sampling. Among them, 612 were left-behind children and 427 were non-left-behind children.@*Results@#There was a positive correlation between deviant behavior and bullying victimization (r=0.17, P<0.01); The average level of positive cognition of left-behind children(2.95) was significantly lower than that of non-left-behind children(3.07) (t=-2.31, P<0.05); Regression analysis showed that participation in daily housework and deviant behavior had a significant positive impact on bullying victimization of left-behind children (β for deviant behavior was 0.55, P<0.01; β for participation in daily housework was 0.27, P<0.05). Relation with peers could significantly negatively predict bullying victimization among left-behind children (β for peer relationship was -0.25, P<0.05). In the deviant behavior model, bullying victimization had a significant positive impact on deviant behavior among left-behind children (β for bullying was 0.58, P<0.01); Parent-child relationship and teacher-student attachment could significantly negatively predict deviant behavior of left-behind children (β for parent-child relationship was -0.34, P<0.01; β for teacher-student relationship was -0.49, P<0.01).@*Conclusion@#The vulnerability of social bonds, deviant behavior and bullying victimization shows intercorrelation among children. Attachment is the common factor that affects deviant behavior and bullying victimization among left-behind children. Participation in daily housework has a unique impact on the bullying experience of left-behind children.
ABSTRACT
Multidiscipline team ( MDT ) provides comprehensive, cross-discipline treatment solutions and effective diagnosis for major, complicated and rare diseases, featuring significantly clinical outcomes. It deserves efforts on how to introduce MDT from clinical work to hospital administration. To this end, this article discussed the application of MDT model at large-scale public hospital administration. MDT hospital administration teams, and such management methods as project management and PDCA, as well as information technology systems were called into play. These measures have effectively resolved long-standing roadblocks commonly encountered, and removed horizontal barriers, sharply raising work efficiency.
