Thyroid-associated ophthalmopathy(TAO)represents the most prevalent chronic orbital disease in adults, significantly compromising patients' quality of life and physical and psychological well-being. Orbital decompression surgery has now emerged as a critical therapeutic intervention for reducing proptosis and alleviating optic nerve compression in TAO patients, with the development of tailored surgical regimens reflecting a key trend. Nonetheless, ophthalmologists encounter persistent hurdles in navigating the selection of optimal surgical techniques and quantifying the necessary extent of decompression. This review systematically synthesizes recent research advances in orbital decompression surgery for TAO. It examines the efficacy, indications, and key technical considerations of various surgical techniques, including orbital fat decompression, orbital wall decompression, and multi-wall decompression. Furthermore, the review summarizes critical factors influencing surgical outcomes and the application of various emerging techniques in orbital decompression procedures. This study aims to enhance the understanding of orbital decompression surgery and provide novel perspectives for ophthalmologists in formulating personalized surgical decompression strategies.

Objective To explore the value of artificial intelligence federated learning system based on chest X-ray films for pathogen diagnosis of community-acquired pneumonia(CAP)in children.Methods Totally 900 cases of CAP children from 2 hospitals were retrospectively enrolled,including bacterial,viral and mycoplasma CAP(each n=300),and chest posteroanterior X-ray films were collected.Meanwhile,chest posteroanterior X-ray films of 5856 children from the publicly available dataset GWCMCx were collected,including 4273 CAP images and 1583 healthy chest images.All above 6756 images were divided into training set(n=5359)and validation set(n=1397)at the ratio of 8∶2.Then a pathogen diagnosis model of children CAP was established based on attention mechanism.Binary and ternary diagnostic algorithms were designed,and federated deployment training was performed.The efficacy of this system for pathogen diagnosis of children CAP was analyzed and compared with DenseNet model.Results Based on all data,the accuracy of the obtained artificial intelligence federated learning system model for diagnosing children CAP was 97.00%,with the area under the curve(AUC)of 0.990.Based on hospital data,the AUC of this system using single imaging data and clinical-imaging data for pathogen diagnosis of children CAP was 0.858 and 0.836,respectively,both better than that of DenseNet model(0.740,both P＜0.05).Conclusion The artificial intelligence federated learning system based on chest X-ray films could be used for pathogen diagnosis of children CAP.

Langerhans cell histiocytosis (LCH) is a rare disease characterized by the proliferation of Langerhans cells and the destruction of local tissue. LCH large occurs in children, whilst incidence of the elderly population is extremely low, and there are few related studies. LCH lesions can involve multiple organs and systems, including bone tissue, lymph nodes, skin, liver, and spleen. However, it is rare that multiple soft tissues are implicated for eldly patients with LCH and present with soft tissue mass as the main manifestation. Here is a report on the clinical features, treatment and prognosis of an elderly LCH with multiple soft tissue masses as the main manifestation, in order to provide clinical reference.

Myeloproliferative neoplasms (MPN) are a group of clonal disorders of hematopoietic stem cells, and JAK2 V617F gene mutation is the main basis for the diagnosis of MPN. Previous studies have shown that BCR-ABL fusion gene and JAK2 V617F gene mutation are mutually exclusive in MPN patients, but in recent years, patients with a double mutation of both genes are often reported. The article synthesizes the relevant domestic and foreign literature in recent years, and reviews the BCR-ABL fusion gene and JAK2 V617F mutation double-positive MPN.

Objective: To analyze the epidemiological characteristics of acute paraquat(PQ)poisoning in children in southwest Shandong, and the risk factors for pulmonary interstitial fibrosis. Methods: This retrospective study was performed on the clinical data of children with acute PQ poisoning admitted from January 2013 to December 2017 in 12 hospitals in southwest Shandong.All participants were divided into pulmonary interstitial fibrosis group and no pulmonary interstitial fibrosis group on the basis of the chest CT 14 days after poisoning.The epidemiological characteristics and risk factors of pulmonary interstitial fibrosis were analyzed. Results: During the study period, a total of 307 children with acute PQ poisoning were admitted to 12 hospitals, of which 61 (19.87%) were suffering from acute PQ poisoning.Forty-nine cases with complete clinical data were analyzed, including 26 male and 23 female patients poisoned by oral.The age distribution ranged from 8 months to 14 years.Poisoning mainly occured from July to September of each year.The mortality of acute PQ poisoning was 8.2%(4/49), and the incidence of pulmonary interstitial fibrosis in survival patients was 44.4%(20/45). Statistical differences (P<0.05) were found between the pulmonary interstitial fibrosis and no pulmonary interstitial fibrosis, with regard to the times of blood purification, the time from poison exposure to blood purification, the application rate of glucocorticoids, the concentration of PQ in urine, the pediatric critical illness score, the time from poison exposure to gastric lavage, the white blood count at admission, serum creatinine, arterial blood lactate, PaO₂, PaCO₂, and PaO₂/FiO₂; however, there was no significant difference in the proportion of blood purification treatment, the mode of blood purification treatment, alanine aminotransferase, aspartate aminotransferase, urea nitrogen, creatine kinase and troponin.Stepwise logistic regression analysis showed that the time from exposure to poison to gastric lavage(OR=0.683, 95%CI 0.210-2.222)and to blood purification(OR=0.0133, 95%CI 0.004-0.042), the times of blood purification(OR=2.862, 95%CI 1.450-5.648), concentration of PQ in urine(OR=1.435, 95%CI 1.085-1.898), and the use of glucocorticoids(OR=0.190, 95%CI 0.048-0.757) were the risk factors for pulmonary interstitial fibrosis(P<0.05). Conclusion Early gastric lavage and blood purification, increasing the frequence of adminitrating purification appropriately, using low-dose glucocorticoids can reduce the incidence of pulmonary interstitial fibrosis of children with acute PQ poisoning.

Objective:To improve the Rapid Arterial Occlusion Evaluation (RACE) scale and to investigate its value in identifying large vessel occlusion (LVO) in patients with acute anterior circulation ischemic stroke (AIS).Methods:Consecutive patients with AIS treated in Liangxiang Hospital of Fangshan District, Beijing through stroke easy access from January 1, 2016 to December 31, 2018 were enrolled prospectively. The clinical data and multimodal CT examinations required to determine LVO were collected. The existing problems in the RACE score were modified. The patients were evaluated by the modified RACE score, RACE score, and National Institute of Health Stroke Scale (NIHSS). The receiver operator characteristic (ROC) curve was used to evaluate the predictive ability of the modified RACE score for LVO, and it was compared with the RACE score and NIHSS score. The ROC curves of LVO predicted by modified RACE score and NIHSS score in patients with left and right hemispheric lesions were compared.Results:A total of 184 patients were included, of which 66 (35.9%) had LVO. The age (64.8±11.7 vs. 60.5±10.8 years; t=2.483, P=0.014), baseline NIHSS score (13 [6.75-17] vs. 5 [2-9]; Z=-6.361, P<0.001) and the proportion of patients with gaze (37.9% vs. 17.4%; χ2=4.696, P=0.030) in the LVO group were significantly higher than those in the non-LVO group. ROC curve showed that the modified RACE score was more effective in identifying LVO than RACE score (area under the curve: 0.812 vs. 0.770; Z=4.654, P<0.001). The best cutoff value of the modified RACE score in predicting LVO was 5, and its predictive sensitivity and specificity were 75.8% and 75.4%, respectively, and the positive and negative predictive values were 63.3% and 84.8%, respectively. A comparison of patients with left hemispheric lesion and those with right hemispheric lesion showed that the ability of the modified RACE score in predicting LVO was more balanced (area under the curve: 0.826 vs. 0.796; Z=0.454, P=0.650), while there was a significant difference in NIHSS score (area under the curve: 0.856 vs. 0.703; Z=2.149, P=0.031). Conclusions:The modified RACE score is better than the original RACE score in the predictive value of LVO in patients with AIS, and its predictive power of LVO in patients with left and right hemisphere stroke is more balanced than the NIHSS score, which may help clinical discrimination and screening for patients suitable endovascular treatment.

Objective:To understand the status of sedation and analgesia treatment and management in pediatric intensive care unit(PICU) in Shandong Province, and to provide the basis for the improvement of sedation and analgesia treatment plan.Methods:This study was a multi-center retrospective study.The PICUs of 6 tertiary hospitals in Shandong Province participated in this study.The data of 1 340 children admitted to these 6 PICUs from January 2016 to December 2018 were collected.The age, gender, the pediatric risk of mortality score Ⅲ at 24 hours after admission, whether they received mechanical ventilation, whether they received sedation and(or) analgesia, whether they were monitored sedation and(or) analgesia, and in-hospital mortality were analyzed.The children were divided into the simple sedation group( n=798), the sedation + analgesia group( n=120) and the non-sedation analgesia group( n=422) according to whether they received sedation and(or) analgesia.The diseases, proportion of mechanical ventilation, incidence of hypotension, average length of stay in PICU and in-hospital mortality were compared among the three groups. Results:The median age of the 1 340 children was (13.3±6.4) months, including 786 males(58.7%). Sedation therapy had been carried out in 6 PICUs, of which 5 PICUs had routine sedation assessment; 4 PICUs had carried out analgesic therapy, of which only 2 had routine pain assessment.A total of 918 children(68.5%)received sedation and(or) analgesia, midazolam was the most commonly used sedative drug, followed by dexmedetomidine, and 526 children(57.3%)were monitored for sedation assessment, the most commonly used assessment method was the Richmond agitation sedation score.One hundred and twenty(9.0%)cases received sedation combined with analgesia, fentanyl was the most commonly used analgesic, and 38 children(31.7%) underwent routine pain assessment.There was no significant difference in age and sex among the three groups.The proportion of surgical diseases and patients received mechanical ventilation(100.0%, 120/120) were the highest in the sedation + analgesia group.The proportion of mechanically ventilated patients was the lowest in the non-sedation analgesia group(11.4%, 48/422). The mean duration of mechanical ventilation in the sedation + analgesia group was slightly shorter than that in the simple sedation group( P>0.05). The incidence of hypotension was highest in the sedation + analgesia group, and lowest in the non-sedation analgesia group[21.7%(26/120) vs.2.1%(9/422), P<0.01]. There was no significant difference in in-hospital mortality and mean PICU stay among three groups. Conclusion:Benzodiazepines are still the main sedative drugs used in PICUs in Shandong Province.In recent years, the usage of dexmedetomidine has gradually increased, but the proportion of analgesic use is very low.At present, analgesic and sedative therapy is mainly used for children after surgery and receiving mechanical ventilation.Although analgesic and sedative therapy does not increase the in-hospital mortality and average length of stay in PICU, it increases the incidence of hypotension.The sedative and analgesic treatment and assessment in the PICU of Shandong Province are still not standardized, mainly reflected in infrequently analgesic treatment and the assessment of sedation and pain, which need to be further improved.

Objective To establish rabbit model bearing VX2 liver tumor using improved technique,and to analyze the relevant impact factors of hepatic artery and portal vein catheterization.Methods Transplanted liver tumors of 60 healthy New Zealand white rabbits were established through open abdominal puncture and hepatic artery and portal vein catheterization.The rabbits were divided into A group (survival) and B group (death) according to whether a short-term (within 7 days after surgery) death occurred or not.The univariate analysis of the factors which could lead to the death of rabbits were analyzed.The Logistic regression models were established with parameters which were significantly different between the 2 groups,and independent risk factors which could lead to the failure of the experiment were analyzed.Results VX2 tumors were successfully implanted in the liver to all 60 rabbits.Nine (9/60,15.00 ％) rabbits died within 7 days,while 51 (51/60,85.00％) rabbits survived,weight ＜ 2.5 kg,additional intraoperative anesthesia,operation time ≥60 min,length of incision ≥5 cm and blood loss of operation ≥25 ml were impact factors (all P＜0.05).Weight ＜ 2.5 kg,additional intraoperative anesthesia and the blood loss of operation ≥25 ml were independent risk factors for death (P＜0.01).Conclusion Relative high success rate of building rabbit models bearing VX2 liver tumor may achieved using hepatic artery and portal vein catheterization.Larger weight of rabbits,training of surgical skills,less intraoperative blood loss are helpful to avoid intraoperative additional anesthesia,thus reducing mortality of rabbits.

OBJECTIVETo investigate the association between exposure to the famine during early life and elevated resting heart rate (RHR) in adulthood.

METHODFrom June 2006 to October 2007, the employees of kailuan group who took part in the health examination were selected. Of those, 18 619 cases who was born during October 1, 1956 to September 30, 1964 in Hebei province were finally included in the analysis based on the inclusion and exclusion criteria. All the subjects were received questionnaire survey, smoking and drinking, physical examination, Lab examination and the measurement of RHR. The subjects of famine exposure group (3 190 cases) were born from October 1, 1959 to September 30, 1961, semi-exposure group (3 851 cases) were born from October 1, 1958 to September 30, 1959 and from October 1, 1961 to September 30, 1962, control group (11 578 cases) were born from October 1, 1956 to September 30, 1958 and from October 1, 1962 to September 30, 1964. The RHR and the detection rate of elevated RHR were compared among the three groups. The Multivariate logistic regression model was used to analyze the association between of exposure to famine during early life and elevated RHR in adulthood.

RESULTSThe RHR level was higher in famine exposure group and semi-exposed group than control group, which were (74.34 ± 9.71), (74.41 ± 9.48) and (73.90 ± 9.45) beat per minute (bpm) (P values were 0.003 and 0.020, respectively). In all of the subjects. The results of multivariate logistic regression showed that exposure of famine during early life increased the risk of elevated RHR in adulthood after adjustment for age, gender and other confounders (OR = 1.10, 95% CI: 1.01-1.21). In men, exposure of famine during early life also increased the risk of elevated RHR in adulthood (OR = 1.15, 95% CI: 1.04-1.28); In women, there was no association between the famine exposure and elevated RHR (OR = 0.92, 95% CI: 0.74-1.14).

CONCLUSIONExposure of famine during early life increases the risk of elevated RHR in adulthood. This negative effect existed mainly in the male.

Background and purpose:Epithelial ovarian cancer has the highest mortality rate of gynecologic cancers and overall survival rates have improved little in the last 20 to 30 years. CXXC ifnger protein 5 (CXXC5) plays an important role in AML (acute myeloid leukemia) and MDS (myelodysplasia). However, little is known about its clinical signiifcance and biological function in epithelial ovarian cancer. This study aimed to investigate the expression of the CXXC5 in ovarian cancer and the effect of the CXXC5 on ES-2 cell proliferation. Methods:①The alteration of CXXC5 in cancer genomics data of TCGA (Cancer Genome Atlas) was analyzed.②The CXXC5 protein in the tissue chips was detected containing 37 benign ovarian cyst and 173 malignant tumor samples. The relationship between the expression of the CXXC5 with the clinicopathological features of patients with ovarian cancer was analyzed by SPSS software;③The cells with the highest CXXC5 expression quantity from 5 ovarian cancer cells were selected by re-al-time quantitative PCR (qRT-PCR) and Western blot.④ES-2 cells with shRNA stable transfection were construted us-ing the strategy of lentivirus infection and analyzed cell proliferation by cell counting kit-8(CCK8). Results:①Through the TCGA database, CXXC5 ampliifcation was found in 7 of 563 cases.②The CXXC5 expression in ovarian malignant carcinoma (39.3%) was higher than that in benign ovarian cyst (13.5%, P=0.003), the histologic type was highly asso-ciated with CXXC5 (43%in serous, 22.9%in mucinous, 23.5%in endometrioid, 67%in clear cell, P=0.014) and there was a signiifcant correlation between CXXC5 and lymph node metastasis (positive vs negative, P=0.022).③The ES-2 cells with shRNA stable transfection had a growth disadvantage (P<0.05). Conclusion:The CXXC5 gene might have an advantage in proliferation of epithelial ovarian carcinoma and be expected to become the biomarker of poor prognosis.
