Objective: To understand the trends in malnutrition among primary and middle school students of Han nationality in Hainan Province from 2005 to 2019, so as to provide a basis for improving nutrition intervention measures for children and adolescents. Methods: A sample of 32 949 Han nationality primary and middle school students aged 7-18 years old in Hainan Province were investigated in 2005, 2010, 2014 and 2019 based on national survey on student physical fitness and health. The Malnutrition Screening Standard of Schoolage Children and Adolescents was used to screen malnutrition. Statistical analysis was performed using the χ2 test and the χ2trend test. Results: In the four surveys conducted during 2005 to 2019, the prevalence of malnutrition among primary and middle school students were 22.12%, 18.80%, 15.89% and 9.56%, respectively, with an increase of -12.56% and an average annual increase of -5.82%. The decreasing trend of malnutrition by year was statistically significant (χ2trend=600.72, P<0.01), and the proportion of emaciation type was the highest (8.87%-20.15%). The detection rates of malnutrition among all students aged 7 to 18 showed a decreasing trend from 2005 to 2019 (χ2trend=56.44, 60.04, 61.48, 42.49, 51.81, 50.81, 72.86, 101.34, 86.38, 24.81, 17.72, 10.38, P<0.01). From 2005 to 2019, the detection rates of malnutrition in boys were higher than that of girls (in 4 surveys), and that in rural students from 2005 to 2014 of 3 surveys were higher than that in towns (χ2=92.07, 35.16, 25.29, 29.98; 64.35, 4.26, 6.32, P<0.05). Conclusions The malnutrition of Han nationality primary and middle school students aged 7-18 years in Hainan Province show a trend of improvement year by year from 2005 to 2019, despite the overall high detection rate. Wasting is the most common type of malnutrition. The epidemic of malnutrition varies by age, sex and areas. Further targeted measures should be taken to strengthen intervention in the diet of primary and middle school students, to improve the nutritional status of children and adolescents.

Objective To investigate the nutritional status of children with Crohn's Disease (CD) at diagnosis and its association with clinical characteristics. Methods A retrospective analysis was performed for the clinical data and nutritional status of 118 children with CD who were admitted to Beijing Children's Hospital,Capital Medical University,from January 2016 to January 2024. A multivariate logistic regression analysis was used to investigate the risk factors for malnutrition. Results A total of 118 children with CD were included,among whom there were 68 boys (57.6％) and 50 girls (42.4％),with a mean age of (11±4) years. Clinical symptoms mainly included recurrent abdominal pain (73.7％,87/118),diarrhea (37.3％,44/118),and hematochezia (32.2％,38/118),and 63.6％ (75/118) of the children had weight loss at diagnosis. The incidence rate of malnutrition was 63.6％ (75/118),and the children with moderate or severe malnutrition accounted for 67％ (50/75). There were 50 children (42.4％) with emaciation,8 (6.8％) with growth retardation,and 9 (7.6％) with overweight or obesity. Measurement of nutritional indices showed a reduction in serum albumin in 83 children (70.3％),anemia in 74 children (62.7％),and a reduction in 25 hydroxyvitamin D in 15 children (60％,15/25). The children with malnutrition had significantly higher disease activity,proportion of children with intestinal stenosis,and erythrocyte sedimentation rate and a significant reduction in serum albumin (P<0.05). The multivariate logistic regression analysis showed that intestinal stenosis was an independent risk factor for malnutrition in children with CD (OR=4.416,P<0.05). Conclusions There is a high incidence rate of malnutrition in children with CD at diagnosis,which is associated with disease activity and disease behavior. The nutritional status of children with CD should be closely monitored.

This study was aimed at summarizing the epidemiological characteristics and spatial-temporal changes of hemorrhagic fever with renal syndrome(HFRS)in Hubei Province,China from 2005 to 2021,to provide scientific evi-dence for HFRS prevention and control.Data on individual HFRS cases and population information in Hubei Province from 2005 to 2021 were collected from the China Disease Pre-vention and Control Information System.The temporal,spa-tial,and demographic distribution characteristics of HFRS cases are described,and statistical methods such as medians,rates,and composition ratios were used for analysis.Joinpoint re-gression and Spearman's rank correlation were used to analyze the temporal trends in incidence rates or composition ratios.Global autocorrelation and hotspot analysis were conducted for spatial clustering analysis.Binary logistic regression was per-formed to analyze risk factors for HFRS mortality.A total of 5 790 HFRS cases were reported from 2005 to 2021,including 117 deaths.The average annual incidence rate was 0.57 per 100 000 population,and the case fatality rate was 2.02％.The overall incidence rate of HFRS in Hubei Province showed an increasing trend(AAPC=4.05％,95％CI:1.32％-6.78％),whereas the case fatality rate showed a decreasing trend over the years(r,=-0.72,P=0.002).HFRS exhibited a bimodal pattern,with peaks in the spring/summer months(May to July)and in the autumn/winter months(November to January of the following year).The incidence rate during the autumn/winter peak was slightly higher than that in the spring/summer peak.The incidence rate in males was higher than in females(RR=2.96,95％CI:2.79-3.14).The three age groups with the highest incidence rates were 60-64 years(747 cases,1.55 per 100 000),65-69 years(515 cases,1.39 per 100 000),and 55-59 years(762 cases,1.23 per 100 000).The incidence rate(2005:0.05 per 100 000;2021:0.08 per 100 000)and proportion(2005:2.69％;2021:1.94％)of HFRS cases in individuals 14 years or younger showed no significant trend over the years(AAPC=0.14％,95％CI:-0.03％-0.31％;AAPC=-3.64％,95％CI:-8.79％-1.50％).The incidence rate(2005:0.58 per 100 000;2021:1.59 per 100 000)and proportion(2005:14.80％;2021:44.31％)in the age group of 60 years or a-bove showed an increasing trend over the years(AAPC=10.52％,95％CI:4.38％-16.66％;AAPC=175.98％,95％CI:143.20％-208.75％).HFRS cases exhibited significant spatial clustering(P＜0.05).The hotspots of HFRS in Hubei Province shifted from the northern region(Xiangyang,Suizhou,Jingmen)in 2005-2007 to the southern region(Qianjiang,Xiantao,Tianmen,Jingzhou)in 2020-2021.Older age(OR=1.02,95％CI:1.01-1.04)and the period of 2005-2008 versus 2017-2021(OR=0.98,95％CI:0.97-0.99)were associated with relatively higher risk of HFRS mortality.In recent years,the HFRS epidemic in Hubei Province has continued to escalate,and areas such as Qianjiang City and other ares in the middle and lower reaches of the Yangtze River have experienced high incidence rates.The population 60 years of age or above is gradually becoming more susceptible to the disease.Targeted measures should be implemented to curb the rising trend of HFRS.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

OBJECTIVE: To investigate the imaging effect of a near-infrared fluorescent targeted probe ICG-NP41 on the neurovascular bundles (NVB) around the prostate in rats. METHODS: A near-infrared fluorescent targeted probe ICG-NP41 was synthesized. An animal model for NVB imaging was established using Sprague-Dawley rats (250-400 g). Experiments were conducted using a custom-built near-infrared windowⅡ(NIR-Ⅱ) small animal in vivo imaging system, and images collected were processed using ImageJ and Origin. The fluorescence signal data were statistically analyzed using GraphPad Prism. The signal-to-background ratio (SBR) for NVB was quantitatively calculated to explore the effective dosage and imaging time points. Finally, paraffin pathology sections and HE staining were performed on the imaging structures. RESULTS: Except for rats in the control group (n=2), right-sided NVB of the rats injected with ICG-NP41 (n=2 per group) were all observed in NIR-Ⅱ fluorescence mode 2 h and 4 h after administration. At 2 h and 4 h, average SBR of cavernous nerve in 2 mg/kg group in fluorescence mode was 1.651±0.142 and 1.619±0.110, respectively, both higher than that in white light mode (1.111±0.036), with no significant difference (P>0.05); average SBR of 4 mg/kg group in fluorescence mode were 1.168±0.066 and 1.219±0.118, respectively, both higher than that in white light mode (1.081±0.040), with no significant difference (P>0.05). At 2 h and 4 h, the average SBR of 2 mg/kg and 4 mg/kg groups in fluorescence mode were higher than that of the control group (SBR=1), the average SBR of the 2 mg/kg group was higher than that of the 4 mg/kg group, and all the above with no significant difference (P>0.05). The average diameter of the nerve measured by full width at half maxima method was about (178±15) μm. HE staining of paraffin sections showed the right major pelvic ganglion. CONCLUSION The near-infrared fluorescent targeted probe ICG-NP41 can be used for real-time imaging of the NVB around the prostate in rats, providing a potential feasible solution for localizing NVB in real time during nerve-sparing radical prostatectomy.

BACKGROUND: Anterior thalamic nuclei (ATN) deep brain stimulation (DBS) is an effective method of controlling epilepsy, especially temporal lobe epilepsy. Mossy fiber sprouting (MFS) plays an indispensable role in the pathogenesis and progression of epilepsy, but the effect of ATN-DBS on MFS in the chronic stage of epilepsy and the potential underlying mechanisms are unknown. This study aimed to investigate the effect of ATN-DBS on MFS, as well as potential signaling pathways by a kainic acid (KA)-induced epileptic model. METHODS: Twenty-four rhesus monkeys were randomly assigned to control, epilepsy (EP), EP-sham-DBS, and EP-DBS groups. KA was injected to establish the chronic epileptic model. The left ATN was implanted with a DBS lead and stimulated for 8 weeks. Enzyme-linked immunosorbent assay, Western blotting, and immunofluorescence staining were used to evaluate MFS and levels of potential molecular mediators in the hippocampus. One-way analysis of variance, followed by the Tukey post hoc correction, was used to analyze the statistical significance of differences among multiple groups. RESULTS: ATN-DBS is found to significantly reduce seizure frequency in the chronic stage of epilepsy. The number of ectopic granule cells was reduced in monkeys that received ATN stimulation (P < 0.0001). Levels of 3',5'-cyclic adenosine monophosphate (cAMP) and protein kinase A (PKA) in the hippocampus, together with Akt phosphorylation, were noticeably reduced in monkeys that received ATN stimulation (P = 0.0030 and P = 0.0001, respectively). ATN-DBS also significantly reduced MFS scores in the hippocampal dentate gyrus and CA3 sub-regions (all P < 0.0001). CONCLUSION ATN-DBS is shown to down-regulate the cAMP/PKA signaling pathway and Akt phosphorylation and to reduce the number of ectopic granule cells, which may be associated with the reduced MFS in chronic epilepsy. The study provides further insights into the mechanism by which ATN-DBS reduces epileptic seizures.

National and regional incidence rates were calculated. The data of cause of injury，injury level，severity of injury，segment and type of fracture，complications，death and other data were collected by medical record questionnaire，and analyzed according to geographical region，age and gender.Results:Medical records of 4，134 patients were included in this study，with a male-to-female ratio of 2.99∶1. The incidence of traumatic spinal cord injury in China in 2018 was 50.484 / 1 million （95% CI 50.122-50.846）. The highest incidence in the Eastern region was 53.791 / 1 million （95% CI 53.217-54.365）. In the whole country，the main causes of injury were high falls （29.58%），as well as in the Western region （40.68%），while the main causes of injury in the Eastern and Central regions were traffic injuries （31.22%，30.10%）. The main injury level was cervical spinal cord in the whole country （64.49%），and the proportion of cervical spinal cord injury in the Central region was the highest （74.68%），and the proportion of lumbosacral spinal cord injury in the Western region was the highest （32.30%）. The highest proportion of degree of injury was incomplete quadriplegia （55.20%），and the distribution pattern was the same in each region. A total of 65.87% of the patients were complicated with fracture or dislocation，77.95% in the Western region and only 54.77% in the Central region. In the whole country，the head was the main combined injury （37.87%），as well as in the Eastern and Central regions，while the proportion of chest combined injury in the Western region was the highest （38.57%）. A total of 32.90% of the patients were complicated with respiratory complications. There were 23 patients （0.56%） died in hospital，of which 17（73.91%） died of respiratory dysfunction. Conclusions:The Eastern region of China has a high incidence of traumatic spinal cord injury.

OBJECTIVE： To analyze the current status and trend of opioids consumption in China， and to provide reference for rational use of opioids. METHODS： Purchasing data on five opioids as fentanyl， morphine， pethidine， oxycodone and hydromorphone， were extracted from the database of the Medicine Economic Information Network from 2014 to 2016. Drug consumption was measured by the daily dose per million population （unit： S-DDD）， and the consumption amount of all opioids and different dosage forms （including oral dosage form， injection and other form） in China and different districts were analyzed and compared. RESULTS： The consumption amount of five opioids increased from 69.62 S-DDD in 2014 to 78.64 S-DDD in 2016. The consumption amount of hydromorphone and oxycodone showed an upward trend， while the consumption amount of morphine was basically unchanged， and the consumption amount of fentanyl and pethidine showed a downward trend. The consumption amount of oral dosage form increased from 39.77 S-DDD in 2014 to 45.61 S-DDD in 2016， the consumption amount of the injection increased from 20.74 S-DDD in 2014 to 24.23 S-DDD in 2016， and the consumption amount of other form decreased from 9.11 S-DDD in 2014 to 8.81 S-DDD in 2016. The consumption amount of oral dosage form was around twice that of injection， with the gap expanding yearly. Regionally， the consumption amount of five opioids in the eastern region was the highest， followed by the western region， and the lowest but the highest growth rate in the central region from 2014 to 2016 （in 2016， consumption amount of eastern， western and central regions were 94.04， 67.90， 63.78 S-DDD， with increase rate of 8.50％， 11.77％， 16.17％， compared with 2014）. Morphine was the most widely used drug in all regions， followed by fentanyl； in the eastern and central regions， the use of oral and injection dosage form increased year by year； in western region， the use of oral dosage forms increased while that of injection decreased year by year. CONCLUSIONS： The opioids consumption in China is increasing overall， with regional differences. Nonetheless， the overall consumption is still low. On the premise of strict supervision， it is necessary to take measures to promote the rational use of opioids in different areas.

Objective To induce adipose-derived stem cells (ADSCs) to differentiate into intermediate mesoderm (IM)-like cells ,with IM-like cells for recellularizing kidney scaffolds,and then to obtain a tissue-engineering kidney with renal structures and functions through co-culture.Methods After inguinal fat pads of Wistar rats were surgically harvested,the primary ADSCs were isolated,induced,and cultured for stem cell identification. ADSCs were inducted to differentiate into IM-like cells by adding glycogen synthase kinase-3 inhibitor (CHIR99021) and fibroblast growth factor 9 (FGF9) at different stages. Seven days later,the IM-like cells were identified. The induced IM-like cells and well-prepared kidney decellularized scaffolds were co-cultured for 10 days to obtain recellularized tissue-engineered kidneys and their differentiation was identified.Results The ADSCs harvested had osteogenic and adipogenic abilities and could express the stem cell surface markers. After 7 days of induction,the positive expressions of odd-skipped related 1 and paired-box 2 were observed in IM-like cells by immunofluorescence technique. After 10 days of co-culture with kidney decellularized scaffolds,the positive expressions of Wilms'tumor 1,GATA-binding protein-3,and E-cadherin were observed by immunofluorescence technique.Conclusion ADSCs can be induced into IM-like cells,and renal cell differentiation can be observed through combining the induced IM-like cells with kidney decellularized scaffolds.
