Objectives:To investigate the efficacy of dexmedetomidine for foraminal endoscopic surgery.Methods:A total of 75 patients with lumbar disc herniation who received treatment at the First Affiliated Hospital of Anhui Medical University between September 2020 and May 2021 were included in this study. Using a case-control study method, these patients were divided into three groups according to different treatment methods, with 25 patients in each group. The three groups underwent a single-segment unilateral approach for foraminal endoscopic surgery. Group A received simple process infiltration anesthesia, while Group B and Group C received a pump injection of 0.5 μg/kg/h dexmedetomidine for 20 minutes prior to surgery. Group B underwent post-surgical anesthesia adjustments, which involved joint process infiltration anesthesia that was seamlessly integrated with a pump-administered dexmedetomidine infusion at a rate of 0.4 μg/kg/h throughout the surgical procedure. Group C received joint process infiltration anesthesia that was seamlessly integrated with a pump-administered dexmedetomidine infusion at a rate of 0.6 μg/kg/h throughout the surgical procedure. Vital signs, sedation status, sedation score, length of hospital stay, pain score (VAS) immediately after surgery, pain scores at 3 and 6 hours after surgery, and changes in vital signs at different points during surgery were compared among the three groups.Results:There were no significant differences in age, sex, or surgical segment among the three groups (all P > 0.05). The postoperative length of hospital stay in Groups A, B, and C was (5.12 ± 1.15) days, (3.02 ± 0.42) days, and (3.82 ± 0.54) days, respectively ( F = 32.04, P < 0.01). At the beginning of surgery, the sedation scores in Groups A, B, and C were (1.22 ± 0.29) points, (1.28 ± 0.36) points, and (1.46 ± 0.38) points, respectively ( F = 3.28, P < 0.05). At 30 minutes after surgery, the sedation scores in the three groups were (2.12 ± 0.22) points, (2.16 ± 0.24) points, and (2.20 ± 0.24) points, respectively ( F = 3.72, P < 0.01). Immediately after surgery, the Visual Analogue Scale (VAS) scores in the three groups were (3.52 ± 0.33) points, (2.92 ± 0.55) points, and (2.82 ± 0.54) points, respectively ( F = 15.16, P < 0.01). At 3 hours after surgery, the VAS scores in the three groups were (3.64 ± 0.39) points, (2.60 ± 0.58) points, and (2.74 ± 0.54) points ( F = 30.47, P < 0.01). At 6 hours after surgery, the VAS scores in the three groups were (3.78 ± 0.43) points, (2.52 ± 0.47) points, and (2.74 ± 0.52) points, respectively ( F = 49.90, P < 0.01). There were significant differences in VAS score, heart rate, and mean arterial pressure among the three groups during articular process puncture, cannula expansion of the intervertebral foramen, and capture of the perinerve protrusion nucleus pulposus ( F = 34.59, 148.65, 164.08, 5.08, 10.81, 38.06, 43.62, 37.46, and 38.76, all P < 0.05). Conclusion:Preoperative dexmedetomidine can effectively maintain hemodynamic stability, ensure sedation levels, reduce postoperative pain, and accelerate patient recovery after surgery.
RESUMEN
Objective To explore the tripartite dynamic game strategy involving the interest relationship between government,hospital and patients in the tiered diagnosis and treatment system,which is conducive to improving the theoretical paradigm and policy logic of tiered diagnosis and treatment system.Methods It built a tripartite evolu-tionary game model to analyse their strategy choices and evolutionary paths,and to solve for stable strategies in the three-way evolutionary game.MATLAB R2018b was used to simulate the model,and the evolution paths and the in-fluence of different strategy choices on the promotion of the tiered diagnosis and treatment system were further ana-lyzed.Results Government,hospitals,and patients will influence each other and eventually evolve to the ideal stable state(1,1,1).Increasing government subsidies will accelerate the convergence of the initial participation probability of hospitals and patients to 1,while excessive subsidies will gradually cause the government to deviate from the strategy of encouraging.Conclusions The government should restrict subsidies for high-quality medical resources to a reasonable range,attract hospital experts,and strengthen regulations.It is important for large hospitals and basic medical institutions to realize the free flow and rational distribution of the resources available to doctors.Patients need to change their inherent concept of medical treatment to achieve orderly medical treatment.
RESUMEN
ObjectiveTo summarize the liver biopsy and clinical features of patients with liver injury of unknown origin, and to investigate the value of ultrasound-guided percutaneous liver biopsy in the diagnosis of liver injury of unknown origin. MethodsA retrospective analysis was performed for the clinical data and ultrasound-guided percutaneous liver biopsy results of 94 patients with liver injury of unknown origin who were admitted to Zhongshan Hospital, Xiamen University, from January 2018 to February 2023. According to the proportion of the patients with different final diagnoses, the patients were divided into autoimmune liver disease (AILD) group, metabolic associated fatty liver disease (MAFLD) group, drug-induced liver injury (DILI) group, alcoholic liver disease (ALD) group, and unknown group. An analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the Bonferroni analysis or the Dunnett’ T3 test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups; the Fisher’s exact test was used for comparison of categorical data between multiple groups. ResultsAll 94 patients with liver injury of unknown origin underwent ultrasound-guided percutaneous liver biopsy after admission, among whom 90 patients (95.7%) had a confirmed diagnosis based on liver biopsy and clinical features. There were 43 patients (45.7%) with AILD, 21 (22.3%) with MAFLD, 15 (16.0%) with DILI, 6 (6.4%) with ALD, 1 (1.1%) with AILD and MAFLD, 1 (1.1%) with hemochromatosis, 1 (1.1%) with Budd-Chiari syndrome, 1 (1.1%) with congenital hepatic fibrosis, and 1 (1.1%) with idiopathic portal hypertension, while 4 patients (4.3%) still had an unknown etiology after liver biopsy. There were significant differences between the patients with top five diagnoses in age (F=4.457, P<0.05) , body mass index (BMI) (F=3.245, P<0.05), aspartate aminotransferase (AST) (H=11.128, P<0.05), gamma-glutamyl transpeptidase (GGT) (H=24.789, P<0.05), alkaline phosphatase (ALP) (H=26.013, P<0.05), IgG (H=19.099, P<0.05), IgM (H=21.263, P<0.05), AMA-M2 positive rate (P<0.05), and ANA positive rate (P<0.05). Compared with the MAFLD group, the AILD group had significantly higher age, AST, GGT, and ALP and a significantly lower BMI; compared with the MAFLD group and the DILI group, the AILD group had significant increases in IgG and IgM; the AILD group had significant increases in the positive rates of AMA-M2 and ANA compared with the other four groups. ConclusionAILD, MAFLD, and DILI are the most common causes in patients with liver injury of unknown origin. Ultrasound-guided percutaneous liver biopsy plays an important role in determining the cause of liver injury of unknown origin, but it is still needed to make a comprehensive analysis based on clinical history, different types of liver injury, laboratory markers, and imaging data.
RESUMEN
Objective To investigate the effect and safety of common electric knife clamp coagulation technique in rabbit thyroidectomy.Methods According to the random number table method,12 New Zealand rabbits were divided into the clamp coagulation group and the ultrasonic scalpel group,with 6 rabbits in each group.The middle part of the thyroid gland in the clamp coagulation group was severed by common electric knife clamp coagulation,while that in the ultrasonic scalpel group was severed by ultrasonic scalpel electrocoagulation.The postoperative conditions of rabbits in the two groups were observ.The severed thyroid tissue was stained with hematoxylin-eosin(HE),and its histopathology after thermal damage was observed under the light microscope.The scope of thermal damage was determined.On the 1st,3rd and 7th day after operation,the auricular venous blood of all rabbits was collected to assess the serum interleukin-6(IL-6)and C-reactive protein(CRP)levels by enzyme-linked immunosorbent assay.The rabbits were killed on the 7th day after operation,and the residual thyroid glands were removed and stained by HE.The pathological changes and inflammatory cell infiltration were observed under the light microscope.Results The rabbits in the 2 groups survived well after operation,and the operative area healed well.No obvious effusion,blood clot,bleeding,incision infection or other complications were found in the residual cavity.Under the light microscope,the surface of the incisal margin of the thyroid gland showed obvious lesions.In the injured area,some cell structures were damaged with coagulated necrosis,some follicles were ruptured,and the contents inside were solidly concentrated and deeply stained.The cytoplasmic eosinophils in parafollicular cells increased,and nuclear pyknosis,fragmentation,and even dissolution occurred.The thermal damage ranges of thyroid tissues in the ultrasonic scalpel and clamp coagulation groups were(0.72± 0.10)mm and(0.88±0.11)mm,respectively.The range of thermal damage in the clamp coagulation group was significantly greater than that in the ultrasonic scalpel group(t=-2.740,P<0.05).On the 1st,3rd and 7th day after surgery,there was no significant difference in the levels of serum CRP and IL-6 between the two groups(P>0.05).The serum IL-6 levels in both groups on the 3rd and 7th day after surgery were significantly higher than those on the 1st day after surgery(P<0.05).There was no significant difference in serum IL-6 level on the 3rd and 7rd day after surgery in the two groups(P>0.05).Thyroid follicular atrophy,glia reduction,follicular epithelial hyperplasia,collagenization and hyperplasia of interstitial fibers were observed in the residual thyroid sections of both groups.No obvious inflammatory cell infiltration was observed.Conclusion In rabbit thyroidectomy,it is safe to remove the thyroid gland using the common electric knife clamp coagulation technique.In terms of preventing thermal damage,the ultrasonic scalpel is better than the common electric knife clamp coagulation technique,but the thermal damage to thyroid tissues caused by the common electric knife clamp coagulation technique is within the safe operating range.

RESUMEN
In the Nicomachean Ethics, Aristotle expounded his thoughts on health by analogy. Through summarizing Aristotle’s main thoughts on health, which including clarifying that the purpose of medicine is health, thinking that only moderation can create, promote and maintain health, emphasizing active-passive doctor-patient relationship, and generally respecting medical discipline and healthy life, this paper founded that his thoughts on health have obvious limitations. The limitations included: ignored the purpose of medicine also included group health; the "moderation" theory lacked accuracy and scientificity; weakened the patient’s right to speak in the doctor-patient relationship and did not give a clear guide to "how to live a healthy life". And then explored the enlightenment of Aristotle’s health thoughts to the development of contemporary society.
RESUMEN
Arsenic, a naturally occurring metal-like chemical element, is one of the 10 chemicals of major public concerns listed by the World Health Organization as harmful to the environment and human health. It can enter the human body through breathing, intaking food, drinking water, skin exposure, and other ways, and long-term exposure to arsenic can cause cancer of multiple organs and impaired function of multiple systems. Epigenetic mechanisms play an important role in arsenic-induced health effects, and research suggested that the carcinogenicity of arsenic may be associated with epigenetic changes. Previous studies focused on the effects of arsenic on DNA methylation modification. In recent years, research showed that 5-hydroxymethylcytosine (5-hmC), an intermediate of active demethylation of DNA, can act as a sensitive epigenetic mark and play a crucial role as a "bridge" between arsenic exposure and health effects. Based on the latest research progress on the role of DNA hydroxymethylation in the health effects associated with arsenic exposure, this article briefly described the relationship between the health effects of arsenic exposure and DNA hydroxymethylation, summarized the possible mechanisms of DNA hydroxymethylation in the health effects associated with arsenic exposure, and provided a scientific basis for preventing and treating the health effects associated with arsenic exposure.
RESUMEN
To explore the feasibility of applying magnetic stimulation technology to the movement control of animal robots, the influence of coil radius, number of turns and other factors on the intensity, depth and focus of magnetic stimulation was simulated and analyzed for robot pigeons. The coil design scheme was proposed. The coil was placed on the head and one of the legs of the pigeon, and the leg electromyography (EMG) was recorded when magnetic stimulation was performed. Results showed that the EMG was significantly strengthened during magnetic stimulation. With the reduction of the output frequency of the magnetic stimulation system, the output current was increased and the EMG was enhanced accordingly. Compared with the brain magnetic stimulation, sciatic nerve stimulation produced a more significant EMG enhancement response. This indicated that the magnetic stimulation system could effectively modulate the functions of brain and peripheral nerves by driving the coil. This study provides theoretical and experimental guidance for the subsequent optimization and improvement of practical coils, and lays a preliminary theoretical and experimental foundation for the implementation of magnetic stimulation motion control of animal robots.

OBJECTIVE@#To investigate the predictive value of complete blood count (CBC) and inflammation marker on the recurrence risk in children with Henoch-Schönlein purpura (HSP).@*METHODS@#One hundred and thirty-three children with HSP admitted to Cangzhou Central Hospital from February 2017 to March 2019 were enrolled. The clinical data of the children were collected, at the time of admission CBC and C-reactive protein (CRP) were detected. After discharge, the children were followed up for 1 year, the clinical data of children with and without recurrence were compared, and multivariate logistic regression was used to analyze the risk factors affecting HSP recurrence. Receiver operating characteristic (ROC) curve should be drawn and the predictive value of CBC and CRP on HSP recurrence should be analyzed.@*RESULTS@#In the follow-up of 133 children, 8 cases were lost and 39 cases recurred, with a recurrence rate of 31.20% (39/125). The age, skin rash duration, proportion of renal damage at the initial onset, percentage of neutrophils, percentage of lymphocytes, platelet count (PLT), mean platelet volume (MPV) and neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), MPV/PLT ratio (MPR), and CRP level of patients with recurrence were statistically different from those without recurrence (P <0.05). Multivariate logistic regression analysis showed that long skin rash duration, renal damage at the initial onset, increased PLR, high PLT, increased MPV and elevated CRP level were independent risk factors for recurrence in children with HSP (P <0.05). The ROC curve analysis showed that the area under the curve (AUC) of the combination of the four blood and inflammation marker (PLT, MPV, PLR and CPR) in the early prediction of HSP recurrence was 0.898, which was higher than the initial renal damage (AUC=0.687) and persistent skin rash time (AUC=0.708), with a sensitivity of 84.62% and a specificity of 83.72%.@*CONCLUSION@#Observation of CBC and CPR can predict the risk of HSP recurrence early and guide early clinical intervention.

Objective@#To explore the epidemiological trend of overweight and obesity, elevated blood pressure and their comorbidities in children and adolescents from Inner Mongolia Autonomous Region during 2016-2021, and to analyze its association with lifestyle, so as to provide reference for formulating prevention and control strategies of regional common comorbidities in schools.@*Methods@#A total of 8 908, 8 222, 9 448, 127 068, 100 778, and 138 540 students aged 10-18 years in Inner Mongolia were selected by stratified random cluster sampling in September each year from 2016 to 2021. Physical examination and questionnaire survey were conducted on the included students. The prevalence trends of overweight,obesity, elevated blood pressure and their co-occurrence were analyzed. Logistic regression was used to compare the prevalence of elevated blood pressure in different body mass index (BMI) groups. After excluding individuals without lifestyle information in 2021, Logistic regression analysis was used on 136 374 subjects to analyze the association between overweight,obesity, elevated blood pressure and their co-occurrence and lifestyle factors.@*Results@#During 2016 to 2021, the prevalence of comorbidity of overweight, obesity with elevated blood pressure among students in Inner Mongolia Autonomous Region were 5.04%,5.14%,4.99%,7.51%,7.60% and 9.45%, respectively . The prevalence of overweight and obesity was 26.94%, 28.07%, 29.62%, 34.19%, 36.71% and 37.53%, respectively. The prevalence of elevated blood pressure were 16.05%, 11.54%, 13.12%, 14.85%, 14.12% and 18.40%, respectively. Except for 2016, the risk of elevated blood pressure in overweight and obese people was higher than that in normal BMI group in other years, and there was a positive correlation between overweight and obesity and elevated blood pressure after gender and urban and rural areas ( P < 0.05 ). In 2021, the detection rate of comorbidity of overweight and obesity with elevated blood pressure among children and adolescents in urban areas was higher than that in suburban counties, and the reporting rate of healthy lifestyle was lower than that in suburban counties ( P <0.05).Skipping breakfast ( OR =1.11,95% CI =1.07-1.16) and non daily moderate and high intensity physical activity( OR =1.27,95% CI =1.20-1.34) were positively correlated with the co-occurrence of overweight,obesity and elevated blood pressure among children and adolescents in Inner Mongolia Autonomous Region. Non daily moderate and high intensity physical activity ≥60 min was positively correlated with elevated blood pressure ( OR =1.11,95% CI =1.07-1.16), and insufficient sleep was positively correlated with overweight,obesity ( OR =1.04, 95% CI =1.01-1.06)( P <0.05).@*Conclusion@#The prevalence of overweight,obesity, elevated blood pressure and their co-occurrence among children and adolescents in Inner Mongolia Autonomous Region is relatively high. Overweight/obesity is an important risk factor for elevated blood pressure, and unhealthy lifestyles are risk factors for co-occurrence of overweight,obesity and elevated blood pressure. Region specific lifestyle interventions are indispensable for the prevention and control of regional common comorbidities. Urban areas may be a key focus for lifestyle interventions.

Methods: The descriptive epidemiological method and spatial analysis method were applied to analyze the epidemiological characteristics of typhoid fever and paratyphoid fever in China during this period by using the surveillance data collected from the National Notifiable Infectious Disease Reporting System of Chinese Center for Disease Control and Prevention. Results: A total of 202 991 cases of typhoid fever were reported in China from 2004 to 2020. More cases occurred in men than in women (sex ratio: 1.18∶1). Most cases were reported in adults aged 20-59 years (53.60%). The incidence rate of typhoid fever decreased from 2.54/100 000 in 2004 to 0.38/100 000 in 2020. The highest incidence rate was reported in young children aged <3 years after 2011, ranging from 1.13/100 000 to 2.78/100 000, and during this period the proportion of cases in this age group increased from 3.48% to 15.59%. The proportion of the cases in the elderly aged ≥60 years increased from 6.46% in 2004 to 19.34% in 2020. The hotspot areas existed in Yunnan, Guizhou, Guangxi and Sichuan Provinces and expanded to Guangdong, Hunan, Jiangxi, and Fujian Provinces. A total of 86 226 paratyphoid fever cases were reported from 2004 to 2020, the male to female ratio of the cases was 1.21∶1. Most cases were reported in adults aged 20-59 years (59.80%). The incidence rate of paratyphoid fever decreased from 1.26/100 000 in 2004 to 0.12/100 000 in 2020. The highest incidence rate of paratyphoid fever was in young children aged <3 years after 2007, ranging from 0.57/100 000 to 1.19/100 000, and during this period the proportion of the cases in this age group increased from 1.48% to 30.92%. The proportion of the cases in the elderly aged ≥60 years increased from 4.52% in 2004 to 22.28% in 2020. The hotspot areas expanded to the east, including Guangdong, Hunan and Jiangxi Provinces, from Yunnan, Guizhou, Sichuan, and Guangxi Provinces. Conclusions: The results showed a low level of incidence of typhoid fever and paratyphoid fever in China with a trend of decreasing per year. The hotspots were mainly in the of Yunnan, Guizhou, Guangxi and Sichuan Provinces, with an expanding trend to eastern China. It is necessary to strengthen the typhoid fever and paratyphoid fever prevention and control in southwestern China, among young children aged <3 years and the elderly aged ≥60 years.

Objective: To analyze the epidemiological characteristics of norovirus-caused acute gastroenteritis outbreaks in China, identify the factors influencing the scale of outbreaks, and provide scientific evidences for early control of norovirus infection outbreaks. Methods: The descriptive epidemiological analysis approach was applied to analyze the incidence of national norovirus infection outbreaks by using the data from the Public Health Emergency Event Surveillance System in China from January 1, 2007 to December 31, 2021. The unconditional logistic regression model was applied to analyze the risk factors that affected the outbreaks' scale. Results: A total of 1 725 norovirus infection outbreaks were recorded in China from 2007 to 2021, with an upward trend in the number of the reported outbreaks. The southern provinces had their annual outbreak peaks from October to March; the northern provinces had two outbreak peaks from October to December and from March to June annually. The outbreaks occurred mainly in southeastern coastal provinces with a trend of gradual spread to central, northeastern and western provinces. The outbreaks mainly occurred in schools and childcare setting (1 539 cases, 89.22%), followed by enterprises and institutions (67 cases, 3.88%) and community households (55 cases, 3.19%). Human to human transmission was the main infection route (73.16%), and norovirus GⅡ genotype was the predominate pathogen causing the outbreaks (899 cases, 81.58%). The time interval between the onset of the primary case and the outbreak reporting M (Q1, Q3) was 3 (2, 6) days and the case number of the outbreak M (Q1, Q3) was 38 (28, 62). The timeliness of outbreak reporting was improved in recent years and the scale of the outbreaks showed a decreasing trend over the years, the differences in reporting timeliness and outbreak scale among different settings were significant (P<0.001). The factors that affected outbreaks' scale included the outbreak setting, transmission route, outbreak reporting timeliness and type of living areas (P<0.05). Conclusions: From 2007 to 2021, the number of the norovirus-caused acute gastroenteritis outbreaks increased in China and the more areas were affected. However, the outbreak scale showed a decreasing trend and the outbreak reporting timeliness was improved. It is important to further improve the surveillance sensitivity and reporting timeliness for the effective control of the outbreak scale.

Objective: To analyze the clinical and genetic characteristics of pediatric patients with dual genetic diagnoses (DGD). Methods: Clinical and genetic data of pediatric patients with DGD from January 2021 to February 2022 in Peking University First Hospital were collected and analyzed retrospectively. Results: Among the 9 children, 6 were boys and 3 were girls. The age of last visit or follow-up was 5.0 (2.7,6.8) years. The main clinical manifestations included motor retardation, mental retardation, multiple malformations, and skeletal deformity. Cases 1-4 were all all boys, showed myopathic gait, poor running and jumping, and significantly increased level of serum creatine kinase. Disease-causing variations in Duchenne muscular dystrophy (DMD) gene were confirmed by genetic testing. The 4 children were diagnosed with DMD or Becker muscular dystrophy combined with a second genetic disease, including hypertrophic osteoarthropathy, spinal muscular atrophy, fragile X syndrome, and cerebral cavernous malformations type 3, respectively. Cases 5-9 were clinically and genetically diagnosed as COL9A1 gene-related multiple epiphyseal dysplasia type 6 combined with NF1 gene-related neurofibromatosis type 1, COL6A3 gene-related Bethlem myopathy with WNT1 gene-related osteogenesis imperfecta type XV, Turner syndrome (45, X0/46, XX chimera) with TH gene-related Segawa syndrome, Chromosome 22q11.2 microduplication syndrome with DYNC1H1 gene-related autosomal dominant lower extremity-predominant spinal muscular atrophy-1, and ANKRD11 gene-related KBG syndrome combined with IRF2BPL gene-related neurodevelopmental disorder with regression, abnormal movement, language loss and epilepsy. DMD was the most common, and there were 6 autosomal dominant diseases caused by de novo heterozygous pathogenic variations. Conclusions: Pediatric patients with coexistence of double genetic diagnoses show complex phenotypes. When the clinical manifestations and progression are not fully consistent with the diagnosed rare genetic disease, a second rare genetic disease should be considered, and autosomal dominant diseases caused by de novo heterozygous pathogenic variation should be paid attention to. Trio-based whole-exome sequencing combining a variety of molecular genetic tests would be helpful for precise diagnosis.

Objective To study the short-term variation patterns of graft viscosity after anterior cruciate ligament reconstruction (ACLR) surgery. Methods Six male New Zealand rabbits were selected. The ACLR animal model of unilateral knee was made with Achilles tendon as the graft. The experimental rabbits were euthanized 15 days after ACLR surgery, with removal of the graft, healthy anterior cruciate ligament (ACL) and Achilles tendon. The cross-sectional area and viscosity coefficient of the graft were measured, and the creep experiments were carried out under equilibrium conditions of 0.1 MPa and 1 MPa, respectively. The viscosity coefficent was calculated. Variation patterns of graft viscosity were summarize. The grafts were compared with healthy ACL. Results The cross-sectional area of the graft increased slowly within 15 days after ACLR surgery. The viscosity of ACL and graft changed nonlinearly. The viscosity coefficient was quite different under different stresses. The viscosity coefficient of the graft decreased with the time after ACLR surgery, which was more obviously under the condition of low stress. Conclusions The results are helpful to guide the implementation of early postoperative rehabilitation plan after ACLR surgery .
