In the process of accelerating the construction of a strong country in health and sports in China， the mode of promoting health has shifted from passive health to active health. Guided by the concept of “active health”， there is a new understanding of the relationship between sports， health， and medical care. The integration of sports and medicine is a concrete manifestation and implementation of the concept of “active health”， and an important measure to implement the Healthy China strategy， which is regarded as an important strategy to promote public health reform. This article reviews the historical path of the integration of sports and medicine from its concept to practical implementation， and finds that China proposed the integration of sports and medicine relatively late， but it has become an intense focus of academic research； The sports and medical departments have launched guidelines for chronic disease exercise and standards related to exercise prescriptions， and local governments in China have explored diversified models of integrating sports and medicine； Under the institutional requirements of top-level design， the exploration of the “integration of sports and medicine” model is flourishing. There are currently problems in promoting the integration of sports and medicine， such as the lack of a “sports and medicine integration” system and a shortage of “sports and medicine integration” talents. Drawing on the international experience of integrating sports and medical services in other countries，We propose a development strategy of “concept first， government leading， and sports and medical cooperation”； We recommend institutional optimization such as improving medical insurance related systems， establishing certification， employment， and management systems for integrated sports and medical talents， and improving the training system for integrated sports and medical talents in universities； We also advocate propose a “dual wheel” promotion path of upgrading hospital rehabilitation centers and expanding community health centers， in order to provide reference for policy formulation and promote the integration of sports and medicine to play a greater role in China’s public health.

Objective:To investigate the value of the ratio of heparin binding protein (HBP) to albumin (ALB) in diagnosis and predict the severity of Kawasaki disease shock syndrome (KDSS).Methods:This study was a retrospective study. Pediatric patients with Kawasaki disease (KD) admitted to the Children's Intensive Care Unit and department of Pediatric Emergency Center of Hunan Children's Hospital from January 2019 to May 2022 were enrolled. The HBP/ALB ratio was calculated according to HBP and serum ALB. The children were divided into three groups (low, medium, and high ratio groups) according to the median and upper and lower quartiles of the HBP/ALB ratio. The differences of each index among the three groups were compared. The receiver operating characteristic curves were drawn to evaluate the clinical value of the HBP/ALB ratio in diagnosis of KDSS and the severity of the disease.Results:A total of 111 cases were included in this study, including 28 cases in the low ratio group, 56 cases in the medium ratio group, and 27 cases in the high ratio group. There were 24 cases with coronary artery damage, 87 cases without coronary artery damage, 27 cases with abnormal ECG findings, and 17 children with KDSS (including 5 cases in the medium ratio group, and 12 cases in the high ratio group). The incidence of KDSS, coronary involvement, and abnormal electrocardiogram proportions in the high ratio group were significantly higher than those in the other two groups. Compared with low and medium ratio groups, the levels of cardiac troponin I, N-terminal pro-brain natriuretic peptide, lactate, stroke output variation, trends in thoracic fluid content, white blood cell count, C-reactive protein, procalcitonin, and D-dimer levels were higher in the high ratio group, while ALB and blood sodium levels were lower in the high ratio group (all P<0.05). There was no significant difference in above indicators between the low and medium ratio groups (all P>0.05). The HBP/ALB ratio had a higher area under the curve, sensitivity, and specificity (0.942, 0.882, and 0.883, respectively) in predicting KDSS compared to HBP alone (0.776, 0.842, and 0.670, respectively). Conclusion:The HBP/ALB ratio could reflect the severity of children with KD and has certain clinical value for prognostic evaluation.

Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.

Objective:To investigate the effect of irisin on inflammatory response in brain tissue of neonatal rats with hy-perbilirubinemia. Method:Sixty-six neonatal SD rats were randomly divided into the normal control group(group A)and the model group(group M).Hyperbilirubinemia models were established by intraperitoneal injection of bilirubin so-lution at the age of 7 days and 10 days.After the last injection,6 rats were randomly selected from group A and M to verify the success of the model establishment,and then group M was randomly divided into group B and group C.Rats in group C were injected with 80 μg/kg irisin solution in lateral ventricles,and the oth-er groups were injected with the same amount of PBS.After the injection into lateral ventricle,groups A,B and C were further divided into three subgroups according to different points of death.Neurobehavioral tests were performed at each time point.Morphology of cortical or hippocampal nerve cells was detected by HE staining,and the concentrations of TNF-α,IL-1β and IL-6 were detected by ELISA. Result:At 12h,there was no significant difference in the time of plane righting reflex among the three groups(P＞0.05);At 24h,the rats in group B and C were longer than those in group A(P＞0.05);At 48h,group B was longer than group A and C(P＜0.05),and there was no significant difference between group A and C(P＞0.05).There was no significant difference in tropism test among the three groups at each time point(P＞0.05).Under the HE staining,the cortex neuron structure in group A were clear and complete but the number of hippocampal neurons was reduce;in group B and C,the number of neurons in cortex and hip-pocampus was decreased,the structure was disordered,and different degrees of pathological damage were ob-served.Group C was better than group B.Under the ELISA,the concentrations of TNF-α,IL-1β and IL-6 in group B were higher than those in group A at each time point(P＞0.05);the concentrations of TNF-α,IL1βand IL-6 in group C were significantly lower than those in group B at each time point(P＞0.05);the concen-tration of TNF-α in the brain tissue of group C was higher than that of group A at 12h(P＞0.05),and at 24h and 48h were lower than those in group A(P＞0.05);the concentration of IL-6 in the brain tissue of group C was lower than that of group A at 12h and 24h(P＞0.05);at 48h,there was no significant difference in the concentration of IL-6 between group C and group A(P＞0.05);the concentration of IL-1β in the brain tissue of group C was not significantly different from that of group A at the three time points(P＞0.05). Conclusion:Irisin can effectively reduce the release of TNF-α,IL-1β and IL-6 in the brain tissue of neonatal rats with hyperbilirubinemia,and play an anti-inflammatory role.

Objective:To explore the clinical characteristics of children with septic shock and analyze the drug resistance of blood culture positive bacteria.Methods:The clinical data,positive blood culture strains and drug sensitivity results of 127 children with septic shock admitted to the Department of Intensive Care Medicine of Hunan Children's Hospital from September 2015 to August 2021 were retrospectively analyzed.Results:A total of 134 strains of bacteria or fungi were isolated from the blood culture samples of 127 children with septic shock,and gram-negative strains were the main ones,accounting for 67.16% (90/134).Haemophilus influenzae and Escherichia coli were the main gram-negative bacteria,accounting for 38.81% (52/134) and 20.15% (27/134)，respectively,while Streptococcus pneumoniae was the main gram-positive bacteria,accounting for 8.21% (11/134),and Candida albicans was the main fungus,accounting for 10.45% (14/134).The number of white blood cells,the levels of serum C-reactive protein,procalcitonin,venous blood sugar and arterial blood lactic acid in patients were all significantly higher than normal values,and the white blood cells count and neutrophil percentage in gram-positive bacterial infections were significantly higher than those with gram-negative bacterial infections and fungal infections( P<0.05).Procalcitonin increased most obviously when infected by gram-negative bacteria,and the difference was statistically significant ( P<0.05).Gram-positive strains were sensitive to vancomycin,teicoplanin,and linezolid,but only 50% of Streptococcus pneumoniae were sensitive to penicillin.Gram-negative strains had relatively high drug resistance,among which Klebsiella pneumoniae were only highly resistant to imipenem,cilastatin and levofloxacin,reaching 50%.Haemophilus influenzae was resistant to cephalosporins and β-amides enzyme antibiotic,and the drug sensitivity rate of lactamase antibiotics was high,with a resistance rate of 50% only to ampicillin,cefuroxime,amikacin,and compound sulfamethoxazole.There were not many fungal strains,and most antifungal drugs were effective against blood culture-positive fungi. Conclusion:The main pathogens of infection in children with septic shock are gram-negative bacteria,and have high resistance to general antibiotics.We should pay attention to their drug resistance when using antibiotics empirically.

Objective To investigate the dosimetric difference between manual and inverse optimization in 3-dimensional (3D) brachytherapy for gynecologic tumors. Methods This retrospective study was conducted among a total of 110 patients with gynecologic tumors undergoing intracavitary combined with interstitial brachytherapy or interstitial brachytherapy. Based on the original images, the brachytherapy plans were optimized for each patient using Gro, IPSA1, IPSA2 (with increased volumetric dose limits on the basis of IPSA1) and HIPO algorithms. The dose-volume histogram (DVH) parameters of the clinical target volume (CTV) including V200, V150, V100, D90, D98 and CI, and the dosimetric parameters D2cc, D1cc, and D0.1cc for the bladder, rectum, and sigmoid colon were compared among the 4 plans. Results Among the 4 plans, Gro optimization took the longest time, followed by HIPO, IPSA2 and IPSA1 optimization. The mean D90, D98, and V100 of HIPO plans were significantly higher than those of Gro and IPSA plans, and D90 and V100 of IPSA1, IPSA2 and HIPO plans were higher than those of Gro plans (P<0.05), but the CI of the 4 plans were similar (P>0.05). For the organs at risk (OARs), the HIPO plan had the lowest D2cc of the bladder and rectum;the bladder absorbed dose of Gro plans were significantly greater than those of IPSA1 and HIPO (P<0.05). The D2cc and D1cc of the rectum in IPSA1, IPSA2 and HIPO plans were better than Gro (P<0.05). The D2cc and D1cc of the sigmoid colon did not differ significantly among the 4 plans. Conclusion Among the 4 algorithms, the HIPO algorithm can better improve dose coverage of the target and lower the radiation dose of the OARs, and is thus recommended for the initial plan optimization. Clinically, the combination of manual optimization can achieve more individualized dose distribution of the plan.

Objective:To evaluate the efficacy and safety of hypomethylating agents (HMA) in patients with myelodysplastic syndromes (MDS) .Methods:A total of 409 MDS patients from 45 hospitals in Zhejiang province who received at least four consecutive cycles of HMA monotherapy as initial therapy were enrolled to evaluate the efficacy and safety of HMA. Mann-Whitney U or Chi-square tests were used to compare the differences in the clinical data. Logistic regression and Cox regression were used to analyze the factors affecting efficacy and survival. Kaplan-Meier was used for survival analysis. Results:Patients received HMA treatment for a median of 6 cycles (range, 4-25 cycles) . The complete remission (CR) rate was 33.98% and the overall response rate (ORR) was 77.02%. Multivariate analysis revealed that complex karyotype ( P=0.02, OR=0.39, 95% CI 0.18-0.84) was an independent favorable factor for CR rate. TP53 mutation ( P=0.02, OR=0.22, 95% CI 0.06-0.77) was a predictive factor for a higher ORR. The median OS for the HMA-treated patients was 25.67 (95% CI 21.14-30.19) months. HMA response ( P=0.036, HR=0.47, 95% CI 0.23-0.95) was an independent favorable prognostic factor, whereas complex karyotype ( P=0.024, HR=2.14, 95% CI 1.10-4.15) , leukemia transformation ( P<0.001, HR=2.839, 95% CI 1.64-4.92) , and TP53 mutation ( P=0.012, HR=2.19, 95% CI 1.19-4.07) were independent adverse prognostic factors. There was no significant difference in efficacy and survival between the reduced and standard doses of HMA. The CR rate and ORR of MDS patients treated with decitabine and azacitidine were not significantly different. The median OS of patients treated with decitabine was longer compared with that of patients treated with azacitidine (29.53 months vs 20.17 months, P=0.007) . The incidence of bone marrow suppression and pneumonia in the decitabine group was higher compared with that in the azacitidine group. Conclusion:Continuous and regular use of appropriate doses of hypomethylating agents may benefit MDS patients to the greatest extent if it is tolerated.

Objective To analyze the characteristics of conventional ultrasound and contrast-enhanced ultrasound(CEUS)in hypovascular renal tumors,and to explore the application value of combining the 2 methods in diagnosing benign and malignant hypovascular renal tumors.Methods The conventional ultrasound and CEUS data of 104 hypovascular renal tumors(76 benign lesions[benign group]and 28 malignant lesions[malignant group])from 99 patients,who were confirmed by postoperative pathology,biopsy pathology or computed tomography(CT)/magnetic resonance imaging(MRI)enhancement combined with long-term follow-up in Ruijin Hospital,Shanghai Jiao Tong University School of Medicine and its Wuxi Branch from Oct.13,2009 to Oct.26,2022,were retrospectively analyzed.The location,size,internal echo,morphology,internal and peripheral blood supply of the lesions were observed by conventional ultrasound,and the perfusion mode,regression pattern,perfusion uniformity and ring enhancement signs were observed by CEUS.Taking the pathological results or confirmed results of CT/MRI enhancement combined with long-term follow-up as the gold standard,the value of conventional ultrasound combined with CEUS in the differential diagnosis of benign and malignant hypovascular renal tumors was analyzed.Results There were significant differences in gender,age of patients and internal echo,contrast agent regression and ring enhancement signs of lesions between the 2 groups(all P＜0.05).The malignant tumors were mostly found in males(78.6％,22/28)with an average age of(58.29±11.76)years old;the masses were mostly hypoechoic(64.3％,18/28),and rapid washout was predominant with CEUS(60.7％,17/28).In the benign group,most of the patients were female(55.3％,42/76),with an average age of(50.64±14.88)years old;the majority of the masses were hyperechoic(64.5％,49/76),and CEUS showed simultaneous washout as the main lesion(56.6％,43/76).Three patients(10.7％,3/28)with ring enhancement signs were all malignant.The diagnostic accuracy(82.7％)and specificity(88.2％)for benign and malignant hypovascular renal tumors were relatively high when combining the diagnostic indicators of ring enhancement signs and hypoechoic.The diagnostic sensitivity(85.7％)and negative predictive value(92.3％)were relatively high when combining the 3 diagnostic indicators of ring enhancement,hypoechoic,and rapid washout.Conclusion Conventional ultrasound combined with CEUS has significant clinical practical value in the differential diagnosis of benign and malignant hypovascular renal tumors.The ring enhancement sign is highly specific in the diagnosis of malignant hypovascular renal tumors.However,if this sign is not significant and conventional ultrasound shows hypoechoic or CEUS exhibits rapid washout,there is a strong suggestion that the mass may be a malignant lesion.

Objective:To investigate the incidence characteristics and influencing factors of non-alcoholic fatty liver disease (NAFLD) in rural Uyghur ethnic group residents in Xinjiang Production and Construction Corps and to provide scientific evidence for early identification and prevention of NAFLD for residents.Methods:A total of 10 158 participants were included from the Xinjiang Uygur ethnic group population cohort. A prospective cohort study and Cox proportional hazards regression model analysis were used to explore the influencing factors and clustering of NAFLD, and the dose-response relationship between related biochemical indicators and the risk of NAFLD was studied using a restricted cubic spline.Results:The cumulative incidence rate of NAFLD was 6.9%, and the incidence density of NAFLD was 12.06/1 000 person-years. The incidence density of NAFLD in females was higher than in males (14.72/1 000 person-years vs. 9.17/1 000 person-years, P<0.001). The incidence density of NAFLD gradually increased with age in the total population, both men and women (all P<0.001). In the general population, an education level of junior high school or above was a protective factor for NAFLD, while older age, divorce, widowhood, overweight, obesity, hypertension, increased glomerular filtration rate, decreased HDL-C, increased LDL-C, and increased ALT were risk factors for NAFLD. Estimated glomerular filtration rate (eGFR), HDL-C, LDL-C, and ALT were non-linearly correlated with the incidence of NAFLD, and there was a significant dose-response relationship between them. Only 19.1% of residents had no NAFLD risk factors; over 80.9% had ≥1 NAFLD risk factors. The risk of NAFLD increased with the number of risk factors. Conclusions:The incidence of NAFLD in rural Uygur ethnic group residents in Xinjiang Production and Construction Corps was relatively low, but most residents had one or more risk factors for NAFLD. Prevention and control of NAFLD in this population cannot be ignored. In addition, people of older age, divorced or widowed, low education level, overweight or obese, hypertension, and abnormal eGFR, HDL-C, LDL-C, and ALT were the high-risk groups of NAFLD that need to be paid attention to in this population.

Objective:To explore the application effect of slope adjustment mattresses in the position management of pediatric intensive care unit (PICU) mechanically ventilated children, in order to seek methods for maintaining effective posture in clinical practice.Methods:This was a quasi-experimental study. In this study, the mechanically ventilated children in PICU of Hunan Children′s Hospital from January 1 to December 31, 2022 were selected by convenient sampling method and divided into control group ( n=21) and experimental group ( n=21) according to random number table. Children in control group used the hospital bed and the traditional posture management, and children in experimental group used the slope adjustment mattress for posture management. The comfort scores, mechanical ventilation time, PICU length of stay, postural decline, unplanned extubation and blood gas analysis index were compared between the two groups. Results:There were 21 cases were admitted in each group ultimately. In the control group, there were 10 males and 11 females, the age was (31.43 ± 27.01) months. There were 11 males and 10 females in the experimental group, the age was (24.57 ± 24.20) months. The comfort scores of the experimental group were (13.57 ± 0.93) and (12.52 ± 0.60) points at the 24 hour and 72 hour respectively; while the comfort scores of the control group were (16.05 ± 1.72) and (15.81 ± 1.66) points at the 24 hour and 72 hour respectively. There were significant differences between the two groups ( t=5.82, 8.52, both P<0.05). The mechanical ventilation time was (5.43 ± 2.48) d, the PICU length of stay was (9.29 ± 3.04) d, and the number of postural decline was (7.52 ± 2.06) times in the experimental group which was superior to control group (8.52 ± 4.65) d, (12.71 ± 6.76) d, (14.95 ± 6.86) times, the differences were significant ( t=2.69, 2.12, 4.75, all P<0.05). There were 0 case of unplanned extubation in the experimental group and 4 cases of unplanned extubation in the control group .The difference was significant ( χ2=5.97, P<0.05). For blood gas analysis, PaCO 2 on the second day were (56.90 ± 6.77) mmHg (1 mmHg=0.133 kPa) in the control group, and (48.67 ± 8.13) mmHg in the experimental group; PaO 2, oxygenation index, PaCO 2 on the third day were (91.19 ± 16.27), (278.19 ± 71.54), (51.62 ± 4.73) mmHg in the control group, and (110.43 ± 21.73), (347.33 ± 90.95), (40.24 ± 5.57) mmHg in the experimental group, the differences were significant ( t values were 7.50-51.00, all P<0.05). There were significant differences about blood gas analysis of time interaction, inter-group interaction, time and inter-group interaction were compared between the two groups ( F values were 3.62-66.38, all P<0.05). Conclusions:Slope adjustment mattresses can maintain effective posture, improve comfort, shorten PICU hospital stay and mechanical ventilation time, significantly reduce posture decline and the risk of unplanned tube withdrawal adverse events in PICU mechanically ventilated children. Improving ventilation and ventilation disorders to enhance blood gas analysis indicators.This appliance can be used as an optimized choice for posture management and expected to effectively improve the quality of nursing care.
