Abstract
Objective: To investigate the effect of the ratio of the maximum diameter of aneurysm sac to age (R) on the long-term efficacy of endovascular aneurysm repair (EVAR) and open surgical repair (OSR) in patients with infrarenal abdominal aortic aneurysm (IAAA). Methods: This is a retrospective cohort study.The clinical data of 317 patients with IAAA who underwent surgical repair in the Department of Vascular Surgery,the Third Affiliated Hospital of Sun Yat-Sen University from January 2016 to October 2022 were retrospectively collected.There were 266 males and 51 females,aged (69.7±8.3) years (range:37 to 87 years).The R value of the patient was calculated and the receiver operating characteristic(ROC) curve was used to establish a model to calculate the optimal cut-off value.The propensity score matching method was used to match the baseline data of patients in the EVAR and OSR group by 3∶1 (the caliper value was 0.05),and the patients were stratified according to the cutoff value of R,and the postoperative efficacy and survival of the patients were analyzed.The primary endpoint was the total mortality rate,and the secondary endpoints included the occurrence of postoperative complications and reintervention.Pearson χ2 or Fisher 's exact test was used for categorical variables,and t test was used for continuous variables to compare differences between groups.The survival curves of the two groups were described by Kaplan-Meier method. Results: After propensity score matching,198 cases were in the EVAR group and 66 cases were in the OSR group.The ROC model showed that the best cut-off value of R value was 0.90,and the two groups were divided into two layers:R<0.90 and R≥0.90.Among them,112 patients with R<0.90 (84 cases of EVAR,28 cases of OSR);there were 152 patients with R≥0.90 (114 cases of EVAR and 38 cases of OSR).The follow-up time was (23.6±1.6) months (range:1 to 70 months).In the R≥0.90 stratification,the total mortality (26.3% vs.5.3%,P<0.05),complication rate (44.7% vs.26.3%,P<0.05), and secondary intervention rate (31.6% vs.13.2%,P<0.05) in the EVAR group were higher than those in the OSR group.In the R<0.90 stratification,there was no significant difference in the total mortality rate (13.1% vs.10.7%,P<0.05),complication rate (28.6% vs.35.7%,P>0.05) and secondary intervention rate (14.3% vs.21.4%, P>0.05) between the two groups. Conclusions: When R≥0.90 in IAAA patients,OSR maybe more beneficial to patients in terms of survival rate,postoperative complication rate and secondary intervention rate than EVAR.When R<0.90,there are no significant differences in survival rate,complication rate and secondary intervention rate between the two surgical methods.

Abstract
Land use/cover change is an important driving factor for carbon stock changes in terrestrial ecosystems and affects the carbon cycle of the whole ecosystem. Taking Kunming City as a case study, based on the modified carbon density coefficient, this study analyzed the spatio-temporal characteristics of carbon storage changes in the terrestrial ecosystem under different land use scenarios from 2000 to 2020 and "three-line" constraints by coupling the carbon storage module of the InVEST model and CA-Markov model. The results showed that:① cultivated land, forest land, and grassland were the main types of land use in Kunming City, and land use transfer also occurred among the three types. ② From 2000 to 2020, the overall carbon storage in Kunming City was low in the south and high in the north, and the carbon storage decreased yearly with a cumulative loss of 5.27×106 t. The degradation of forest land and grassland was the main reason for the decrease in carbon storage. ③ From 2020 to 2030, the carbon storage of the four scenarios should decrease, and the decline in carbon storage in the inertia development scenario was the most obvious, which was mainly caused by the rapid expansion of construction land. The cultivated land protection scenario effectively slowed down the reduction in carbon storage compared with the inertia development scenario. The ecological protection scenario could enhance the carbon sequestration capacity of the study area, with carbon storage reaching 262.49×106 t, but could not effectively control the reduction in cultivated land area. The scenario of preventing urban expansion effectively inhibited the disorderly expansion of construction land and indirectly prevented further reduction in carbon storage. Therefore, the cultivated land protection scenario, ecological protection scenario, and urban expansion prevention scenario can be considered comprehensively in the study area, which could not only increase the carbon sink space of the study area but also ensure food and ecological security.

Abstract
OBJECTIVE Epidemiological studies have reported an association between epilepsy and dementia. However, the causal relationship between epilepsy and the risk of dementia is not clear. We aimed to inspect the causal effect of epilepsy on memory loss and dementia. METHODS We analyzed summary data of epilepsy, memory loss, and dementia from the genome-wide association study (GWAS) using the two-sample Mendelian randomization (MR) method. We used the estimated odds ratio of memory loss and dementia associated with each of the genetically defined traits to infer evidence for a causal relationship with the following exposures: all epilepsy, focal epilepsy (including focal epilepsy with hippocampal sclerosis, lesion-negative focal epilepsy, and focal epilepsy with other lesions), and genetic generalized epilepsy (including childhood absence epilepsy, generalized tonic-clonic seizures alone, Juvenile absence epilepsy, and Juvenile myoclonic epilepsy). RESULTS According to the result of MR using the inverse variance weighted method (IVW), we found that genetically predicted epilepsy did not causally increase the risk of memory loss and dementia (p > 0.05). Results of the MR-Egger and weighted median method were consistent with the IVW method. CONCLUSIONS No evidence has been found to support the notion that epilepsy can result in memory loss and dementia. The associations observed in epidemiological studies could be attributed, in part, to confounding or nongenetic determinants.

Abstract
Treatment of blood blister-like aneurysms (BBAs) of the supraclinoid internal carotid artery (ICA) with flow diverters (FDs) has become widespread in recent years. However, ruptured blood blister-like aneurysm (BBA) of ICA treatment with flow diverter-assisted coil embolization (FDAC) remains controversial. Moreover, limited direct comparative studies have been conducted between the two treatment modalities, FDs and FDAC, for BBAs. The purpose of this study was to document our experience and evaluate the effectiveness and safety of FDAC. We conducted a retrospective analysis of clinical and radiological information from ten patients who experienced ruptured BBAs of the supraclinoid ICA at our center from January 2021 to February 2023. The technical details of FDAC for ruptured BBAs were described, and the technical steps were named "pipeline embolization device (PED)-Individualized shaping(microcatheter)-Semi deploying-Rivet(coils)-Massage(microwire)" as the PEISSERM technique. Clinical outcomes were assessed using the modified Rankin Scale (mRS), whereas radiological results were determined through angiography. A pooled analysis was implemented, incorporating data from literature sources that reported perioperative and long-term clinical and angiographic outcomes of ruptured BBAs treated with FD and FDAC strategies, along with our data. Data in our analysis pool were categorized into FD and FDAC strategy groups to explore the preferred treatment modalities for BBAs. The PEISSERM technique was utilized to treat ten patients, seven males, and three females, with an average age of 41.7 years. A single PED was deployed in conjunction with coils in all ten patients. All PEDs were documented to have good wall apposition. The immediate postoperative angiograms demonstrated Raymond grade I in ten aneurysms. Angiographic follow-up of nine patients at 4-25 months showed total occlusion of the aneurysms. At the most recent follow-up, the mRS scores of nine patients hinted at a good prognosis. Pooled analysis of 233 ICA-BBA cases of FD revealed a technical success rate of 91% [95% confidence interval (CI), 0.88 to 0.95], a rate of complete occlusion of 79% (95% CI, 0.73 to 0.84), a recurrence rate of 2% (95% CI, 0.00 to 0.04), a rebleed rate of 2% (95% CI, 0.00 to 0.04), and the perioperative stroke rate was 8% (95% CI, 0.04 to 0.11). The perioperative mortality was 4% (95% CI, 0.01 to 0.07). The long-term good clinical outcome rate was 85% (95% CI, 0.80 to 0.90). The mortality rate was 6% (95% CI, 0.03 to 0.09). Results from the subgroup analysis illustrated that the FDAC strategy for BBAs had a significantly higher immediate postoperative complete occlusion rate (P < 0.001), total occlusion rate (P = 0.016), and a good outcome rate (P = 0.041) compared with the FD strategy. The FDAC strategy can yield a higher rate of good outcomes than the FD strategy. The PEISSERM technique employed by the FDAC is a reliable and effective treatment approach as it can minimize the hemodynamic burden of BBA's fragile dome, thereby achieving an excellent occlusion rate. The PEISSERM technique in the FDAC strategy contributes to understanding the BBA's treatment and offers a potentially optimal treatment for BBA.

Abstract
PURPOSE/OBJECTIVE(S) It has been hypothesized that incidental dose to low axilla contributes to regional control in patients receiving whole breast irradiation (WBI), especially in patients with limited metastatic sentinel nodes who were spared from subsequent axillary dissection. We aimed to compare axillary dose between intensity-modulated radiotherapy (IMRT) and intensity-modulated proton radiotherapy (IMPT). MATERIALS/METHODS Dosimetric comparisons between IMRT and IMPT were conducted in 15 patients treated with WBI without planned regional node irradiation (RNI). The prescribed dose was 40.05 Gy (RBE)/15 Fx. Axillary lymph nodes levels I, II (ALN I, ALN II) and rotter's lymph nodes (RN) were contoured and evaluated. RESULTS The dose to the axilla was generally low for IMPT, with mean dose to ALN I, ALN II, and RN of 896.31, 194.64, and 2111.58 cGy (RBE), respectively. The mean V90% and V50% of ALN I was higher for IMRT (11.5 cm3, 22.9% of structure volume, p < 0.0001; 36.1 cm3, 66.6%, p < 0.0001) compared to IMPT (1.1 cm3, 2.0%; 8.1cm3, 15.9%). Similar finding was found in other low axilla. Mean dose to total ALN caudal to axillary vein was 936.6 cGy (RBE) in IMPT compared to 2407.3 cGy in IMRT (p < 0.0001). Within all substructures of axilla, mean dose to RN was the highest, but it remains lower in IMPT than in IMRT [2111.58 cGy (RBE) versus 3510.88 cGy, p < 0.0001]. CONCLUSION WBI treated with IMPT leads to a significant reduction of axilla dose compared to IMRT. In clinical scenarios like Z0011 or likewise requiring incidental irradiation to the low axilla without additional RNI, contouring should be modified based on individual risk.

Abstract
BACKGROUND Physical activity plays an important role in the recovery of breast cancer survivors. However, previous studies have shown that most breast cancer survivors have inadequate levels of physical activity. OBJECTIVE This study aimed to explore the influencing factors of physical activity in breast cancer survivors. METHODS Twelve participants aged 38 to 65 years who had completed surgery and related treatment for breast cancer were recruited from the outpatient service of a hospital in Daqing, China. The phenomenological method was used in this qualitative research. Semistructured interviews were conducted to explore the influencing factors of physical activity in breast cancer survivors. Colaizzi's 7-step analysis method was used to code the data and identify descriptive themes. RESULTS Four themes affecting the daily physical activity of breast cancer patients were extracted: perception and motivation (knowledge about benefits, goals, and motivation for physical activity), symptom burden (psychological and physical symptoms), social support (support from oncology staff, family, and peers) and environmental resources (seasonal impact, community resources). CONCLUSION The physical activity of breast cancer survivors is affected by many factors. Oncology providers need to strengthen assessment, identify barriers, and provide interventions to promote the patients' participation in physical activity and to improve their quality of life. IMPLICATION FOR PRACTICE It is necessary for providers to integrate medical and social support resources, use strategies to enhance motivation, and effectively solve barriers to increase physical activity in breast cancer survivors.

Abstract
OBJECTIVE To identify susceptible biomarkers for the development of bipolar disorder (BD), we conducted a Mendelian Randomization (MR) design to screen circulating proteins for the potential risk of bipolar disorder systematically. METHODS We performed a two-sample Mendelian randomization (MR) analysis to estimate the causality of 4782 human circulating proteins on the risk of bipolar disorder. 376 circulating biomarkers were selected in MR estimation (4406 circulating proteins with less than 3 SNPs were excluded) with 5368 European descents. GWAS meta-analysis of the potential role of all-cause bipolar disorder arose from the Psychiatric Genomics Consortium (41,917 cases, 371,549 controls). RESULTS After IVW and sensitivity analysis, 4 circulating proteins having causal effects on bipolar disorder were identified. ISG15, as a key player in the innate immune response, decreased the risk of bipolar disorder causally (OR = 0.92, 95% CI = 0.89-0.94, P = 1.46e-09). Furthermore, MLN decreased the risk of bipolar disorder causally (OR = 0.94, 95% CI = 0.91-0.97, P = 1.04e-04). In addition, SFTPC (OR = 0.91, 95% CI = 0.86-0.96, P = 4.47e-04) and VCY (OR = 0.86, 95% CI = 0.77-0.96, P = 8.55e-03) presented a suggestive association with bipolar disorder. CONCLUSIONS Our findings indicated that ISG15 and MLN showed evidence of causality in bipolar disorder and provided a promising target for the diagnosis and treatment of diseases.

Abstract
The majority of low-grade gliomas (LGGs) in adults invariably progress to glioblastoma over time. Spectrin β non-erythrocytic 2 (SPTBN2) is detected in numerous tumors and is involved in tumor occurrence and metastasis. However, the specific roles and detailed mechanisms of SPTBN2 in LGG are largely unknown. The present study performed pan-cancer analysis for the expression and prognosis of SPTBN2 in LGG using The Cancer Genome Atlas and The Genotype-Tissue Expression. Western blotting was used to detect the amount of SPTBN2 between glioma tissues and normal brain tissues. Subsequently, based on expression, prognosis, correlation and immune infiltration, non-coding RNAs (ncRNAs) were identified that regulated SPTBN2 expression. Finally, tumor immune infiltrates associated with SPTBN2 and prognosis were performed. Lower expression of SPTBN2 was correlated with an unfavorable outcome in LGG. A significant correlation between the low SPTBN2 mRNA expression and poor clinicopathological features was observed, including wild-type isocitrate dehydrogenase status (P<0.001), 1p/19q non-codeletion (P<0.001) and elders (P=0.019). The western blotting results revealed that, compared with normal brain tissues, the amount of SPTBN2 was significantly lower in LGG tissues (P=0.0266). Higher expression of five microRNAs (miRs/miRNAs), including hsa-miR-15a-5p, hsa-miR-15b-5p, hsa-miR-16-5p, hsa-miR-34c-5p and hsa-miR-424-5p, correlated with poor prognosis by targeting SPTBN2 in LGG. Subsequently, four long ncRNAs (lncRNAs) [ARMCX5-GPRASP2, BASP1-antisense RNA 1 (AS1), EPB41L4A-AS1 and LINC00641] were observed in the regulation of SPTBN2 via five miRNAs. Moreover, the expression of SPTBN2 was significantly correlated with tumor immune infiltration, immune checkpoint expression and biomarkers of immune cells. In conclusion, SPTBN2 was lowly expressed and correlated with an unfavorable prognosis in LGG. A total of six miRNAs and four lncRNAs were identified as being able to modulate SPTBN2 in a lncRNA-miRNA-mRNA network of LGG. Furthermore, the current findings also indicated that SPTBN2 possessed anti-tumor roles by regulating tumor immune infiltration and immune checkpoint expression.

Abstract
Objectives: To construct a nomogram incorporating important prognostic factors for predicting the overall survival of patients with colorectal cancer with peritoneal metastases treated with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC), the aim being to accurately predict such patients' survival rates. Methods: This was a retrospective observational study. Relevant clinical and follow-up data of patients with colorectal cancer with peritoneal metastases treated by CRS + HIPEC in the Department of Peritoneal Cancer Surgery, Beijing Shijitan Hospital, Capital Medical University from 2007 January to 2020 December were collected and subjected to Cox proportional regression analysis. All included patients had been diagnosed with peritoneal metastases from colorectal cancer and had no detectable distant metastases to other sites. Patients who had undergone emergency surgery because of obstruction or bleeding, or had other malignant diseases, or could not tolerate treatment because of severe comorbidities of the heart, lungs, liver or kidneys, or had been lost to follow-up, were excluded. Factors studied included: (1) basic clinicopathological characteristics; (2) details of CRS+HIPEC procedures; (3) overall survival rates; and (4) independent factors that influenced overall survival; the aim being to identify independent prognostic factors and use them to construct and validate a nomogram. The evaluation criteria used in this study were as follows. (1) Karnofsky Performance Scale (KPS) scores were used to quantitatively assess the quality of life of the study patients. The lower the score, the worse the patient's condition. (2) A peritoneal cancer index (PCI) was calculated by dividing the abdominal cavity into 13 regions, the highest score for each region being three points. The lower the score, the greater is the value of treatment. (3) Completeness of cytoreduction score (CC), where CC-0 and CC-1 denote complete eradication of tumor cells and CC-2 and CC-3 incomplete reduction of tumor cells. (4) To validate and evaluate the nomogram model, the internal validation cohort was bootstrapped 1000 times from the original data. The accuracy of prediction of the nomogram was evaluated with the consistency coefficient (C-index), and a C-index of 0.70-0.90 suggest that prediction by the model was accurate. Calibration curves were constructed to assess the conformity of predictions: the closer the predicted risk to the standard curve, the better the conformity. Results: The study cohort comprised 240 patients with peritoneal metastases from colorectal cancer who had undergone CRS+HIPEC. There were 104 women and 136 men of median age 52 years (10-79 years) and with a median preoperative KPS score of 90 points. There were 116 patients (48.3%) with PCI≤20 and 124 (51.7%) with PCI>20. Preoperative tumor markers were abnormal in 175 patients (72.9%) and normal in 38 (15.8%). HIPEC lasted 30 minutes in seven patients (2.9%), 60 minutes in 190 (79.2%), 90 minutes in 37 (15.4%), and 120 minutes in six (2.5%). There were 142 patients (59.2%) with CC scores 0-1 and 98 (40.8%) with CC scores 2-3. The incidence of Grade III to V adverse events was 21.7% (52/240). The median follow-up time is 15.3 (0.4-128.7) months. The median overall survival was 18.7 months, and the 1-, 3- and 5-year overall survival rates were 65.8%, 37.2% and 25.7%, respectively. Multivariate analysis showed that KPS score, preoperative tumor markers, CC score, and duration of HIPEC were independent prognostic factors. In the nomogram constructed with the above four variables, the predicted and actual values in the calibration curves for 1, 2 and 3-year survival rates were in good agreement, the C-index being 0.70 (95% CI: 0.65-0.75). Conclusions: Our nomogram, which was constructed with KPS score, preoperative tumor markers, CC score, and duration of HIPEC, accurately predicts the survival probability of patients with peritoneal metastases from colorectal cancer treated with cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy.

Abstract
This study explored the correlation between semaphorin 4D (SEMA4D) and the prognosis and survival time of patients with melanoma combined with liver cancer. A total of 272 patients were recruited, and clinical and follow-up data were recorded. The expression levels of SEMA4D and SEMA3B were determined. Pearson's χ2 test and Spearman's rank correlation coefficient were used to analyze the relationship between prognosis and the assessed parameters of melanoma patients. Univariate and multivariate Logistic regression and Cox proportional risk regression analyses were used for further analysis. Additionally, receiver operating characteristic curve and survival curves of subjects were plotted. The Pearson's χ2 test showed that the prognosis of melanoma patients was significantly correlated with age, tumor grade, and decreased SEMA4D expression. Additionally, Spearman's correlation coefficient analysis showed that age, tumor grade, and SEMA4D expression were significantly correlated with prognosis. Univariate logistic regression analysis showed that age and tumor grade, and SEMA4D expression, were significantly correlated with prognosis. Older patients, a higher tumor grade, and lower SEMA4D expression were associated with a poorer prognosis. Multivariate logistic regression analysis showed that older patients had a poorer prognosis, and patients with lower SEMA4D expression levels had a significantly worse prognosis than patients with higher SEMA4D expression levels. Kaplan-Meier analysis showed that the survival time of older patients was lower than that of the younger patients. The survival times of patients with lower SEMA4D expression levels were significantly lower than that of patients with higher SEMA4D expression levels. Multivariate Cox regression analysis showed that the survival time of older patients was lower than that of younger patients. The survival time of melanoma patients with low SEMA4D expression was significantly lower than that of patients with higher SEMA4D expression. SEMA4D was significantly associated with melanoma, and lower SEMA4D expression was associated with a poorer survival prognosis in melanoma patients.

Abstract
Objective We present our initial experience using the microcatheter-guided compartment packing (MCP) technique for endovascular embolization of acutely ruptured complex intracerebral aneurysms (ARCIAs) and evaluate the safety, feasibility, and efficiency of this technique. Methods This retrospective, single-center study included 28 patients who underwent coil embolization using the MCP technique for ARCIAs at our institution between January 2021 and January 2022. The MCP technique was the placement of microcatheters in different compartments within the aneurysm to deploy the coils simultaneously or sequentially. Patient demographics, aneurysm characteristics, procedural parameters, grade of occlusion, complications, and clinical results were analyzed. The clinical outcomes were evaluated with modified Rankin Scale (mRS) scores. Results Of the 28 patients successfully treated with the MCP technique, 24 (85.7%) aneurysms were considered as complete occlusions (Raymond I) based on the immediate postembolization angiogram results. Complications occurred in 2/28 treatments, including guidewire perforation with subarachnoid hemorrhage and cerebral vasospasm-related cerebral infarction. An angiography follow-up demonstrated complete occlusion in 25/28 aneurysms. Twenty-six (92.9%) patients had favorable 90-day outcomes (mRS 0-2) after the endovascular coil embolization. Conclusion The MCP technique is simple, safe, and effective, achieving good packing density and initial occlusion rate when used to treat ARCIAs.

Abstract
OBJECTIVE We aimed to describe the initial experience of mechanical thrombectomy using tandem double stent retrievers combined with intermediate catheter aspiration to treat refractory severe hemorrhagic (SH)-cerebral venous sinus thrombosis (CVST). METHODS All refractory SH-CVST patients treated with mechanical thrombectomy using tandem double stent retriever (SR) combined with intermediate catheter aspiration (MT-TDSA) in our institution were retrospectively reviewed. MT-TDSA is a technique that fully engages the clot with double SRs and retrieves the clot using a double SR in combination with aspiration from an intermediate catheter. Demographics, clinical manifestation, medical history, the location of the occluded venous sinus, intraoperative details, procedure-related complications, and modified Rankin Scale (1, 6, 12 months postoperatively) were collected and analyzed. RESULTS Fourteen patients (median age, 43 years) with refractory SH-CVST were treated with MT-TDSA between January 2016 and January 2020. Ten of 14 (71.4%) had a successful intraoperative recanalization rate (>90%) using MT-TDSA. No procedure-related complications occurred. Eleven patients had good clinical outcomes (modified Rankin Scale score 0-2 at 12 months postoperatively). CONCLUSIONS MT-TDSA for refractory SH-CVST might improve clot-capturing ability and remove blood clots from cerebral venous sinuses effectively and safely, achieving good clinical outcomes.

Abstract
Objective Glioblastoma (GBM), a type of malignant glioma, is the most aggressive type of brain tumor and is associated with high mortality. Hexose-6-phosphate dehydrogenase (H6PD) has been detected in multiple tumors and is involved in tumor initiation and progression. However, the specific role and mechanism of H6PD in GBM remain unclear. Methods We performed pan-cancer analysis of expression and prognosis of H6PD in GBM using the Genotype-Tissue Expression Project (GTEx) and The Cancer Genome Atlas (TCGA). Subsequently, noncoding RNAs regulating H6PD expression were obtained by comprehensive analysis, including gene expression, prognosis, correlation, and immune infiltration. Finally, tumor immune infiltrates related to H6PD and survival were performed. Results Higher expression of H6PD was statistically significantly associated with an unfavorable outcome in GBM. Downregulation of hsa-miR-124-3p and hsa-miR-516b-5p in GBM was detected from GSE90603. Subsequently, OSMR-AS1 was observed in the regulation of H6PD via hsa-miR-516b-5p. Moreover, higher H6PD expression significantly correlated with immune infiltration of dendritic cells, immune checkpoint expression, and biomarkers of dendritic cells. Conclusions The OSMR-AS1/ miR-516b-5p axis was identified as the highest-potential upstream ncRNA-related pathway of H6PD in GBM. Furthermore, the present findings demonstrated that H6PD blockading might possess antitumor roles via regulating dendritic cell infiltration and immune checkpoint expression.

Abstract
Objective: To determine the priority of diabetes prevention and control measures in the perspective of the economy and importance, and provide theoretical support for guiding relevant departments to implement measures based on actual economic level. Methods: An online survey was conducted on the importance, feasibility and implementation of major chronic disease prevention and control measures in 488 national demonstration areas for comprehensive chronic disease prevention and control. The content of the survey was divided into individual and group levels, with 10 dimensions and 44 measures, to obtain the scores of the economy and importance. IPA model was used to divide the dimension index of diabetes prevention and control into quadrants. The standardized factor load coefficient of the second-order confirmatory factor analysis was used to determine the priority of dimension index in the same quadrant. The priority of prevention and control measures in each dimension was determined by the discriminant parameter of project response theory. Results: The mean scores of economy and importance were 66.50 and 89.94, respectively, and the matrix was divided into four quadrants. The first quadrant was the "highest priority" with high importance and economy, including medical insurance and family doctors, health education, high-risk detection and intervention, patient management and community action. The second quadrant was characterized as high importance but low economy, which was the priority for improvement, including only one dimension of complication screening. The third quadrant was the lowest priority due to low importance and economy, including personal health service evaluation and follow-up, environmental support, diabetes co-infection prevention and glycemic policy. The last quadrant had low importance but high economy, which was the second improvement level. The priority measures in different quadrants were: (1) the highest priority: blood lipid control, occupational site, prevention and control work plan, blood glucose testing, family doctor contract service; (2) the priority improvement: annual neuropathy screening; (3)the lowest priority: universal access to risk scoring, healthy eating, healthy dining innovations and tuberculosis screening. Conclusion: IPA model can be used to construct a decision-making model for diabetes prevention and control and determine the priority of corresponding measures.

Abstract
Objective: To investigate the oncological and functional efficacy and safety of transoral robotic surgery (TORS) in the treatment of oropharyngeal carcinoma. Methods: Twenty-six patients with oropharyngeal cancer were enrolled who underwent TORS at Beijing United Hospital from June 1, 2017 to December 31, 2020. Among them, 22 patients were males and 4 were females, aged 39 to 76 years old. T1-2 patients accounted for 88.5% (23/26). Clinicopathological data including the time of removal of gastric and endotracheal tube were collected. The SPSS software package was used for survival analysis, and the overall survival rate and disease-free survival rate were calculated. Results: All the 26 patients with oropharyngeal cancer received TORS without conversion to open surgery, and 20 of them underwent simultaneous cervical lymph node dissection. TORS operation time ranged from 65 to 360 minutes with an average of 215 minutes. Intraoperative blood loss ranged from 5 to 600 ml with an average of 70 ml. Four patients (15.4%) underwent tracheotomy, of whom 3 patients had the removals of tracheal tubes within 1 month after surgery and 1 case remained to wear a tube by the end of follow-up. Twelve patients (46.2%) underwent gastric tube implantation, among them, 11 patients had removals of gastric tubes within 1 month after surgery and 1 patient died of oropharyngeal hemorrhage 13 days after operation. One patient (3.8%) had a positive surgical margin and others had pathologically negative surgical margins. Sixteen patients (61.5%) received postoperative radiotherapy, of whom 11 patients (42.3%) received platinum-based concurrent chemotherapy. The median follow-up time was 21.5 months (0.4 to 45 months). The overall survival and the disease-free survival rates were 83.0% and 75.8%, respectively. Conclusion: The application of TORS in treatment of oropharyngeal cancer can achieve good oncological and functional outcomes in selected patients.

Abstract
Aortoiliac occlusive disease (AIOD) refers to the stenosis and occlusion of the distal abdominal aorta and(or) bifurcation of the aortoiliac artery,which is mainly caused by atherosclerosis,leading to pelvic and lower limb ischemia.Open surgery has always been the main treatment for complex AIOD.However,in recent years,with the development of endovascular surgery technologies and medical instruments,its treatment concept has been greatly changed.More and more clinical evidence has proved that the long-term efficacy of endovascular therapy is not inferior to that of traditional open surgery,so minimally invasive endovascular therapy has become the preferred treatment for AIOD.

Abstract
Objective: To evaluate the safety and efficacy of cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (CRS+ HIPEC) in patients with peritoneal carcinomatosis from colorectal carcinoma (CRC PC). Methods: The clinical and follow-up data of 90 consecutive CRC PC patients underwent CRS+ HIPEC in Beijing Shijitan Hospital from January 2015 to June 2018 were collected. Kaplan-Meier method and parallel Log rank test were used for survival analysis. Cox regression model was used for univariate and multivariate analysis. Results: A total of 90 CRC PC patients underwent CRS+ HIPEC, the median age was 53 years (rage: 13 to 81 years), and 51 cases were male, while other 39 were female. The median overall survival (mOS) was 21.9 months (95%CI: 15.7, 28.1). The 1-, 2-, 3-, and 5-year survival rates were 77.8%, 48.6%, 21.1%, and 5.5%, respectively. The incidence rate of serious adverse event (SAE) was 8.9% (8/90). The mortality rate of perioperative period was 2.2% (2/90). Univariate analysis showed the age (P=0.040), primary tumor site (P=0.020), preoperative carbohydrate antigen 125 (CA125) level (P<0.001), peritoneal cancer index (PCI) (P<0.001), completeness of cytoreduction (CC) (P<0.001), ascites (P=0.012) and postoperative adjuvant chemotherapy (P<0.001) were significantly associated with the OS. Multivariate Cox-analysis identified preoperative CA125 level(P=0.033), CC of 0 to 1 (P=0.014), and adjuvant chemotherapy postoperative (P=0.002) were independent prognostic factor for OS. Conclusions: CRS+ HIPEC can improve survival for CRC PC patients with acceptable morbidity and mortality. Stringent patient selection and complete CRS are two key factors for better survival.

Abstract
Objective: To examine the therapeutic effects of drug-coated balloon (DCB) and bare metal stent (BMS) on primary femoropopliteal disease (FPAD) in the real world. Methods: This was a retrospective analysis of single-center follow-up results at 12,24,and 36 months of patients with FPAD lesions that were treated with DCB and BMS at Department of Aortic and Vascular Surgery, Fu Wai Hospital.One-to-one propensity score matching(PSM) was performed to balance the covariance between DCB group (137 cases) and BMS group (100 cases). Freedom from clinically driven target lesion reintervention rate(fCD-TLR) was determined by Kaplan-Meier curve.Log-rank test was used to compare the rates of fCD-TLR between DCB and BMS groups at 12,24,36 months post-operation. Results: After PSM, there were both 71 patients in each group,aged (68.0±9.6) years(range: 46 to 90 years) and (68.8±7.3) years(range: 48 to 87 years),lesion lengths were (119.6±14.2)mm(range:40 to 380 mm) and (110.8±13.1)mm(range:40 to 400 mm). The median follow-up period were 24.3 months (range:5.8 to 55.1 months).There was no death,amputation or reintervention within the 30 days after operation.The rates of fCD-TLR for DCB group at 12,24 and 36 months were 97.2%,85.9%,69.1%, and 95.8%,83.1%,59.2% for BMS group.There was no statistical difference between the two groups by Log-rank test (P=0.551). Conclusion: DCB and BMS can both maintain favorable clinical effects in FPAD patients at 12,24,36 months post-operation.

Abstract
Objective: To investigate the clinical indicators for preoperative prediction of impacted ureteral stones and analyze the predictive value of ureteral wall area(UWA). Methods: A total of 197 patients who underwent ureteroscopic lithotripsy due to ureteral stones at our institution from January to December 2020 were retrospectively analyzed. Preoperative patient age, gender, body mass index (BMI), history of hypertension, diabetes mellitus, side of stone, location of stone, maximum diameter of stone, CT value of stone, C-reactive protein (CRP), creatinine, renal pelvis diameter, ureteral wall thickness and UWA were collected. Patients were divided into impacted and non-impacted groups according to whether the stones were impacted intraoperatively. Univariate analysis was used to compare the differences in each clinical indicator between the two groups, and multivariate logistic regression was performed to analyze the independent predictors of impacted stones for those with differences. The receiver operating characteristic (ROC) curve was used to analyze the predictive power of each independent predictor, and the Delong test was used to analyze whether the difference in the area under the curve (AUC) of each independent predictor was statistically significant. Results: All 197 patients successfully completed the operation, aged 51 (36, 56) years; 137 males and 60 females. According to the results of ureteroscopy, they were divided into 82 cases of impacted ureteral stones and 115 cases of non-impacted ureteral stones. Univariate analysis showed that there were significant differences in maximum stone diameter, stone CT value, renal pelvis diameter, ureteral wall thickness and ureteral wall area between the two groups (P<0.05); There was no significant difference in age, gender, BMI, history of hypertension, diabetes, stone side, location of stone, CRP and creatinine (P>0.05). Multivariate logistic regression analysis showed that stone CT value (P<0.01), ureteral wall thickness (P<0.001) and ureteral wall area were independent predictors of impacted ureteral stones (P<0.001). The ROC curve was used to compare the predictive efficacy of independent predictors of stone CT value, ureteral wall thickness and ureteral wall area. The area under the ureteral wall area curve was the largest (AUC = 0.901, 95%CI: 0.859-0.943, P<0.001), followed by ureteral wall thickness (AUC = 0.799, 95%CI: 0.736-0.862, P<0.001) and stone CT value (AUC = 0.700, 95%CI: 0.626-0.775, P<0.001). By Delong test, there were significant differences in AUC between ureteral wall area and stone CT value (Z=4.527, P<0.001) and ureteral wall thickness (Z=3.407, P<0.001). The best predictive value of ureteral wall area was 79.6 mm2. The sensitivity and specificity of this critical value for predicting ureteral incarcerated calculi were 80.1% and 89.5%. Conclusions: The UWA, ureteral wall thickness as well as the CT value of stones were all independent predictors of impacted ureteral stones, and UWA had a better predictive value.

Abstract
Objective: Using Meta-analysis to evaluate the relation of sugar-sweetened beverages (SSBs) intakes and artificially sweetened beverages (ASBs) intakes with risk of incident cardiovascular disease. Methods: "Sugar-sweetened beverages"(SSBs),"artificially sweetened beverages"(ASBs),"coronary heart disease"(CHD),"stroke","cardiovascular disease"(CVD), and related terms (both in English and in Chinese) were searched in Pubmed, EMBASE, Web of Science, Cochrane library, ProQuest, China National Knowledge Infrastructure (CNKI), Wanfang databases, and VIP Chinese Science and Technology Journal. Besides, it searched for additional references in websites including Clinical Tirals.gov and International Clinical Trials Registry Platform. The time was up to May 31st 2020. Stata 13 software was used to calculate pooled RR, perform heterogeneity test, and assess publication bias. Results: A total of 14 articles were included from the 40 804 articles retrieved, including 12 articles from European and American countries and 2 articles from Asian countries. The baseline mean age of the participants ranged from 52 to 69 years, and the mean follow-up time was from 6 to 26 years. Meta-analysis showed that compared with those in the lowest group, the RR (95%CI) for those in the highest group of SSBs consumption was 1.11 (1.04-1.08) for CHD, 1.10 (1.01-1.19) for stroke, and 1.09 (0.96-1.24) for CVD events. The corresponding RR (95%CI) comparing extreme groups of ASBs consumption was 1.10 (0.98-1.23) for CHD, 1.19 (1.09-1.29) for stroke, and 1.32 (1.15-1.52) for CVD events. Further analysis for subtypes of stroke showed that compared with the lowest group, the RR (95%CI) for those in the highest groups of SSBs consumption was 1.10 (0.99-1.22) for ischemic stroke and 0.86 (0.71-1.04) for hemorrhagic stroke. The corresponding RR (95%CI) comparing extreme consumption of ASBs was 1.23 (1.04-1.46) for ischemic stroke and 1.33 (1.03-1.72) for hemorrhagic stroke. Conclusion: Higher consumption of SSBs or ASBs may lead to increased risk of incident CHD and stroke (particularly ischemic stroke).

Abstract
Spin-valley locking in monolayer transition metal dichalcogenides has attracted enormous interest, since it offers potential for valleytronic and optoelectronic applications. Such an exotic electronic state has sparsely been seen in bulk materials. Here, we report spin-valley locking in a Dirac semimetal BaMnSb2. This is revealed by comprehensive studies using first principles calculations, tight-binding and effective model analyses, angle-resolved photoemission spectroscopy measurements. Moreover, this material also exhibits a stacked quantum Hall effect (QHE). The spin-valley degeneracy extracted from the QHE is close to 2. This result, together with the Landau level spin splitting, further confirms the spin-valley locking picture. In the extreme quantum limit, we also observed a plateau in the z-axis resistance, suggestive of a two-dimensional chiral surface state present in the quantum Hall state. These findings establish BaMnSb2 as a rare platform for exploring coupled spin and valley physics in bulk single crystals and accessing 3D interacting topological states.

Abstract
Objective: Peritoneal carcinomatosis refers to a group of heterogeneous (primary or secondary) malignancies in the surface of the peritoneum. Cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) is a comprehensive treatment strategy aiming at peritoneal carcinomatosis. This study analyzed the efficacy and safety of CRS+HIPEC in patients with peritoneal carcinomatosis, and explored prognostic factors. Methods: In this descriptive case-series study, the clinicopathological data of 1384 consecutive patients with peritoneal carcinomatosis treated in Zhongnan Hospital of Wuhan University (330 patients) and Shijitan Hospital of Capital Medical University (1054 patients) from January 2004 to January 2020 were collected retrospectively. Treatment patterns of CRS+HIPEC characteristics (operative time, number of resected organs, number of stripped peritoneum, number of anastomosis, and HIPEC regimens), safety [blood loss volume, postoperative severe adverse event (SAE) and treatment outcome], survival time and prognostic factors influencing survival were analyzed. The SAE was defined as grade III-IV adverse event according to the Peritoneal Surface Oncology Group International Textbook. Perioperative period was defined from the day of CRS+HIPEC to postoperative 30th day. OS was calculated from the day of CRS+HIPEC to the date of death or the last follow-up. Kaplan-Meier method was used for survival analysis, and log-rank test was used for comparison between groups. Cox regression model was used to identify the prognostic factors. Results: Among 1384 peritoneal carcinomatosis patients, 529 (38.2%) were male; median age was 55 (10-87) years old; median body mass index (BMI) was 22.6 kg/m(2); peritoneal carcinomatosis of 164 (11.8%) patients were from gastric cancer, 287 (20.7%) from colorectal cancer, 356 (25.7%) from pseudomyxoma peritonei, 90 (6.5%) from malignant peritoneal mesothelioma, 300 (21.7%) from gynecological cancer or primary peritoneal carcinoma, and 187 (13.5%) from retroperitoneal sarcoma, lung cancer, breast cancer, and other rare tumors. The median duration of CRS+HIPEC was 595 (90-1170) minutes, median number of resected organs was 2 (0-10), median number of resected peritoneal area were 4 (0-9), median peritoneal cancer index (PCI) was 21(1-39). Completeness of cytoreduction (CC) score of 0-1 was observed in 857 cases (61.9%). Regarding HIPEC regimens, there were 917 cases (66.3%) with cisplatin plus docetaxel, 183 cases (13.2%) with cisplatin plus mitomycin, 43 cases (3.1%) with adriamycin plus ifosfamide, and the other 240 cases (17.3%) with modified regimens. Perioperative SAE developed in 331 peritoneal carcinomatosis patients (23.9%) with 500 cases, of whom 21 patients (1.5%) died during the perioperative period due to ineffective treatment, while the others recovered after active treatment. During median follow-up time of 8.6 (0.3-82.7) months, there were 414 deaths (29.9%). The median OS was 38.2 months (95% CI: 30.6-45.8), and the 1-, 3-, 5-year survival rate was 73.5%, 50.4% and 39.3%, respectively. The median OS of peritoneal carcinomatosis patients from gastric cancer, colorectal cancer, pseudomyxoma peritonei, malignant peritoneal mesothelioma and female genital cancer or primary peritoneal carcinomatosis was 11.3 months (95% CI: 8.9-13.8), 18.1 months (95% CI: 13.5-22.6), 59.7 months (95% CI: 48.0-71.4), 19.5 months (95% CI: 6.0-33.0) and 51.7 months (95% CI: 14.6-88.8), respectively, and the difference among groups was statistically significant (P<0.001). Univariate and multivariate analyses revealed that the primary gastric cancer (HR=4.639, 95% CI: 1.692-12.724), primary colorectal cancer (HR=4.292, 95% CI: 1.957-9.420), primary malignant peritoneal mesothelioma (HR=2.741, 95% CI: 1.162-6.466), Karnofsky performance status (KPS) score of 60 (HR=4.606, 95% CI: 2.144-9.895), KPS score of 70 (HR=3.434, 95% CI: 1.977-5.965), CC score of 1 (HR=2.683, 95% CI: 1.440~4.999), CC score of 2-3 (HR=3.661,95% CI: 1.956-6.852) and perioperative SAE (HR=2.588, 95% CI: 1.846-3.629) were independent prognostic factors influencing survival with statistically significant differences (all P<0.05). Conclusions: CRS+HIPEC is an effective integrated treatment strategy for patients with peritoneal carcinomatosis, which can prolong survival with acceptable safety. Preoperative evaluation of patients' general condition is necessary and CRS+HIPEC should be carefully considered to perform for patients with preoperative KPS score <80. During the operation, the optimal CRS should be achieved on condition that safety is granted. In addition, it is necessary to prevent perioperative SAE to reduce the risk of death in peritoneal carcinomatosis patients.

Abstract
Objective: To examine the outcomes of surgical repair for patients with total subclavian artery occlusion. Methods: A retrospective analysis was performed on 67 patients with subclavian artery occlusion disease admitted at Ward 1 of Aortic and Vascular Surgery Center, Fuwai Hospital from January 2016 to July 2019. The age was, and There were 51 male patients and 16 females with an age of (61.7±8.2) years (range: 37 to 79 years). The t-test, Mann-Whitney U-test, χ(2) test, and Fisher's exact test were used to analyze the factors related to the technique success. The Kaplan-Meier curve was used to calculate the cumulative patency rate and plot the corresponding survival curves, and the Log-rank test was used for comparison. The length from the subclavian artery ostial to the occlusion area was used as a variable to plot the receiver operating characteristic curve, and the optimal cut-off value was determined by the Youden index. Results: Eighteen patients received open surgery. Forty-nine patients with subclavian artery occlusion accepted endovascular repair, of which 38 patients succeeded (31 cases on left side and 3 cases on right side). Fifteen patients failed with endovascular therapy, of which 10 cases received elective surgery and 5 cases received conservative therapy. The success rate of endovascular repair was 69.4%(34/49). Among them, the success rate of left subclavian artery occlusion was 81.6%(31/38), while the right side was 3/11. Patients with the length from the subclavian artery ostial to the occlusion area ≥6 mm were more likely to get success (23/34 vs. 4/15, χ(2)=5.506, P=0.019). In the endo-group, one patient had hemorrhage in the left chest. In the open-group, one patient had lymphatic leakage. Follow-up period ranged from 3 to 46 months with a median of 22 months. The patency of endovascular repair group and the open surgery group was 92.6% and 90.8% at 12-month, while 82.9% and 84.3% at 24-month, respectively. The cumulative patency rates of smoking patients and non-smoking patients after endovascular treatment were 70.2% vs. 100% (P=0.048) at 24-month. No independent prognosis factors were identified through the Cox proportional risk model which significantly affected postoperative patency rates for patients with subclavian artery occlusion. Conclusions: Part of patients with subclavian artery occlusion can be treated by endovascular therapy. The success rate of left subclavian artery occlusions is higher than right sides. The length from the subclavian artery ostial to the occlusion area affected the success rate of repair.

Abstract
BACKGROUND AND OBJECTIVE The aim of the study is to investigate the value of serum iron and hemoglobin levels for predicting acute seizures following aneurysmal subarachnoid hemorrhage (aSAH). METHODS Clinical and laboratorial data from patients with ruptured intracranial aneurysms were collected in the retrospective study. Age, sex, symptom onset, history of diabetes and hypertension, history of coronary artery disease, temperature, Hunt-Hess grade, Fisher grade, aneurysm location, hemoglobin, serum potassium, sodium, calcium, phosphorus, and iron were collected. Acute seizures were determined as seizures within 1 week following aSAH. Propensity score matching (PSM) analyses were performed to correct imbalances in patient characteristics between seizure and non-seizure groups. RESULTS A total of 760 patients were included. Incidence of acute seizures following aSAH was 6.4%. In the univariate analysis, significant differences were detected in age, admission Hunt-Hess grade, Fisher grade, hemoglobin, serum sodium, and serum iron between seizure and non-seizure groups. In multivariate logistic regression model, lower serum iron was considered as a risk factor for acute seizures (OR 0.182, 95% CI 0.084-0.393, p = 0.000), as well as lower hemoglobin (OR 0.977, 95% CI 0.962-0.993, p = 0.004) and higher serum sodium (OR 1.072, 95% CI 1.003-1.145, p = 0.039). After PSM, there were no significant differences in age, admission Hunt-Hess grade, Fisher grade, and serum sodium between seizure and non-seizure groups. The matched seizure group had lower serum iron and hemoglobin levels compared with the matched non-seizure group (p < 0.05). The optimal cutoff value for serum iron and hemoglobin levels as a predictor of acute seizure after aSAH was determined as 9.9 mmol/L (sensitivity was 81.63% and the specificity was 65.40%) and 119 g/L (sensitivity was 63.27% and the specificity was 70.18%), respectively. CONCLUSIONS Serum iron and hemoglobin levels were inversely associated with a high risk of acute seizures following aSAH.

Abstract
The energy adjustment models in nutritional epidemiological studies could substantially reduce the confounding effect of total energy intake from the intake of dietary components, and it could explore the real relationship between the intake of dietary component and research outcomes. Four energy adjustment models were introduced in this article, including the standard multivariate model, multivariate nutrient residual model, energy partition model, and multivariate nutrient density model. The four energy adjustment models were applied to analyze the association between the intake of saturated fatty acids and the risk of all-cause mortality based on the data of the US National Health and Nutrition Examination Survey. The consistent results of different energy adjustment models could indicate that the four models could better control the confounding effect of total energy intake.

Abstract
PURPOSE Targeted radiation therapy has seen an increased interest in the past decade. In vitro and in vivo experiments showed enhanced radiation doses due to gold nanoparticles (GNPs) to tumors in mice and demonstrated a high potential for clinical application. However, finding a functionalized molecular formulation for actively targeting GNPs in tumor cells is challenging. Furthermore, the enhanced energy deposition by secondary electrons around GNPs, particularly by short-ranged Auger electrons is difficult to measure. Computational models, such as Monte Carlo (MC) radiation transport codes, have been used to estimate the physical quantities and effects of GNPs. However, as these codes differ from one to another, the reliability of physical and dosimetric quantities needs to be established at cellular and molecular levels, so that the subsequent biological effects can be assessed quantitatively. METHODS In this work, irradiation of single GNPs of 50 nm and 100 nm diameter by X-ray spectra generated by 50 and 100 peak kilovoltages was simulated for a defined geometry setup, by applying multiple MC codes in the EURADOS framework. RESULTS The mean dose enhancement ratio of the first 10 nm-thick water shell around a 100 nm GNP ranges from 400 for 100 kVp X-rays to 600 for 50 kVp X-rays with large uncertainty factors up to 2.3. CONCLUSIONS It is concluded that the absolute dose enhancement effects have large uncertainties and need an inter-code intercomparison for a high quality assurance; relative properties may be a better measure until more experimental data is available to constrain the models.

Abstract
Objective: To investigate the characteristics of frailty in the elderly male patients with chronic kidney disease (CKD) and the effects of renal function on the incidence of frailty. Methods: A total of 105 non-dialysis CKD patients aged ≥65 years who were admitted to the Chinese PLA General Hospital between October 1, 2018 and January 30, 2019 were included in this study. Their clinical data and laboratory indicators were collected. Frailty was defined according to Fried frailty criteria. According to the frailty scores, the participants were categorized as non-frail (n=37), intermediately frail (n=37) and frail (n=31). The association of frailty and the level of estimated glomerular filtration rate (eGFR) in the patients was analyzed using the model of multivariate Logistic regression. Results: Among the 105 patients, the mean age was 74 (68, 77) years old. The incidence of frail and intermediate frail was 35.2% (37/105) and 29.5% (31/105), respectively. Multivariate logistic analysis showed statistically significant associations of frailty with age (OR=1.14, 95%CI:1.08-1.20, P<0.001), body mass index (OR=0.87, 95%CI:0.79-0.95, P=0.001) and the level of eGFR (OR=0.98, 95%CI:0.96-0.99, P=0.003) in those patients. The incidence of frail in patients with eGFR<45 ml·min(-1)·(1.73 m(2))(-1) and 45-59 ml·min(-1)·(1.73 m(2))(-1) was 1.02 (OR=2.02, 95%CI: 1.06~3.87) and 0.84 (OR=1.84, 95%CI: 1.05-3.22) times higher than that of eGFR≥60 ml·min(-1)·(1.73 m(2))(-1), respectively. Conclusion: The incidence of frailty in the elderly patients with CKD is affected by many factors, such as age, body mass index and renal function, and increases with decreased renal function.

Abstract
Objective: To explore the spatial-temporal distribution and epidemic characteristics of hemorrhagic fever with renal syndrome (HFRS) in Hebei province from 2005 to 2016. Methods: Records of HFRS cases reported from each county in Hebei during January 2005 to December 2016 were collected from National Notifiable Disease Surveillance System (NNDSS). Global and local spatial association statistics were used to measure the spatial autocorrelation and software GeoDa 1.2.0. Software SaTScan 9.4.1 was used to analyze spatiotemporal clusters. Software ArcGIS 10.2 was used to visualize the yearly scan results. Results: In Hebei province, a total of 8 437 human HFRS cases reported from 170 counties with an annual incidence rate of 0.99/100 000 population during 2005-2016. The peak incidence season was spring. Global spatial autocorrelation analysis on the incidence of HFRS at county-level showed that the value of Moran's I were all above 0 (P<0.05), indicating that the significant spatial cluster. The result of local indicators on spatial association (LISA) analysis revealed that identified hot spots were mainly in northeastern area, while cold spots were found in some counties of central and southern areas. Spatial-temporal scan detected that the primary cluster of HFRS incidence was mainly distributed in Qinhuangdao city and Tangshan city, including 11 counties (city/district): Beidaihe district, Haigang district, Funing district, Shanhaiguan district, Changli county, Lulong county and Qinglong Manchu autonomous county in Qinhuangdao city, and Qian'an city, Laoting county, Luanzhou city and Luannan county in Tangshan city (RR=39.64, P<0.001), during January-July in 2005. Conclusions: There were significant spatial-temporal cluster of HFRS in Hebei from 2005 to 2016. The cluster areas of HFRS were mainly in northeastern Hebei, it is necessary to strengthen the prevention and control programs of HFRS in these areas.

Abstract
Objectives: To evaluate the prognostic significance of Adult Comorbidity Evaluation-27 (ACE-27) for elderly patients (age ≥70 years) with locoregionally advanced nasopharyngeal carcinoma (NPC) treated with Intensity-Modulated Radiotherapy (IMRT), with or without chemotherapy. Methods: 206 elderly patients with locoregionally advanced NPC treated from December 2006 to December 2016 were involved into analysis as the training cohort. Besides, a separate cohort of 72 patients from the same cancer center collected between January 2003 and October 2006 served as the validation cohort. By using propensity score matching (PSM), we created a balanced cohort by matching patients who received chemoradiotherapy with patients who received IMRT alone. Treatment toxicities were calculated between CRT and RT groups using the χ2 test. The primary endpoint was cancer-specific survival (CSS). Multivariate analysis was performed to assess the relative risk for each factor by using a Cox's proportional hazards regression model. Results: The median follow-up was 39.0 months (range = 3-137 months). In the PSM cohort, patients in the CRT group achieved comparable survival compared with patients in the RT group. The 3-year CSS rate was 64.3% and 65.2%, respectively (P =0.764). In multivariate analysis, the addition of chemotherapy to IMRT was not an independent prognostic factor for CSS, whereas a high ACE-27 score was an independent risk factor. In subgroup analysis with ACE-27 score ≥ 2, the 3-year CSS rate was worse in patients from the CRT group (63.5% vs. 46.3%, P = 0.041). Conclusions: CRT is comparable to IMRT alone for elderly patients with locoregionally advanced NPC. The ACE-27 tool may help to identify high-risk subgroup for poor disease outcome and tailor individualized treatment.

Abstract
OBJECTIVE To establish animal models and investigate the impact of unilateral hemilaminectomy (ULHL) and different degrees of facetectomy (FT) on the cervical spinal biomechanics. METHODS Twenty sheep were randomly and evenly divided into 4 groups. No operation was performed for group A, right C4-C6 ULHL was performed for group B, right C4-C6 ULHL and 50% ipsilateral C4-C5 FT was performed for group C, right C4-C6 ULHL and 100% ipsilateral C4-C5 FT was performed for group D. Animals of group A, B, C and D were sacrificed 24 weeks after operating and fresh cervical spine specimens were acquired, biomechanically tested and these data were compared to determine whether ULHL and different degrees of FT led to long-term differences in range of motion. RESULTS (1) Changes of the total range of motion of cervical spine 24 weeks after surgery: the total range of motion of group D (60.2°±8.6°) was significantly greater than group A (40.7°±6.4°) and group B (41.2°±13.1°) under flexion-extension station, the total range of motion of group D (81.5°±15.7°) was significantly greater than that of group A (56.7°±12.2°) and group B (57.7°±12.8°) under lateral bending station, and the total range of motion of group D (38.5°±17.5°) had no obvious increase compared with group A (26.4°±9.9°) and group B (27.1°±10.9°) under axial rotation station. The total range of motion of group C had no obvious increase compared with group A and group B under flexion-extension station (44.1°±11.7°), lateral bending station (73.6°±11.4°) and axial rotation station (31.3°±11.5°). (2) Changes of the intersegmental motion 24 weeks after surgery: the intersegmental motion of group D (20.3°±4.6°) at C4-C5 was significantly greater than that of group A (11.7°±3.4°) and group B (11.9°±2.1°) under flexion-extension station, the intersegmental motion of group D (26.8°±3.5°) at C4-C5 was significantly greater than that of group A (15.2°±3.1°) and group B (16.2°±3.2°) under lateral bending station, the intersegmental motion of group D (15.2°±3.5°) at C4-C5 was significantly greater than that of group A (6.6°±2.3°) and group B (7.1°±1.9°) under axial rotation station. The intersegmental motion of group C (21.2°±4.1°) at C4-C5 was significantly greater than that of group A and group B under lateral bending station, the intersegmental motion of group C at C4-C5 had no obvious increase compared with group A and group B under flexion-extension station (15.7°±3.7°) and axial rotation station (10.3°±3.1°). CONCLUSION ULHL does not affect cervical stability, ULHL and 50% ipsilateral FT does not affect the long-term cervical stability, ULHL and 100% ipsilateral FT can lead to long-term instability under lateral bending and flexion-extension station.

Abstract
OBJECTIVE To investigate the values of diffusion tensor imaging (DTI) and virtual reality (VR) techniques in design surgery program of gliomas near eloquent regions. METHODS In this study, 35 cases were retrospectively analyzed with gliomas involved language areas or rolandic regions operated in Department of Neurosurgery, Peking University Third Hospital from January 2015 to January 2019. Surgery programs were performed by Dextroscope virtual reality system. The pre-operative data, such as the magnetic resonance imaging (MRI), magnetic resonance arteriography (MRA) and DTI was transferred into the VR computer for restitution,Tumors, neural fiber tracts and blood vessels were reconstructed to simulate operation and design individual surgical plan. Neurological function was evaluated 1 week, 1 month and 3 months after operation. RESULTS Virtual reality three-dimensional images of the 35 cases were successfully achieved, including neural fiber tracts,blood vessels and the lesions. The displacement and destruction of fiber tracts, the anatomic relationship between tumor and important fiber bundle, artery and vein could be shown clearly. Surgical simulation and surgery program of VR of the 35 patients were successfully performed. The 3D images obtained from virtual reality near to the real surgery. Ten of the 35 cases were defined as rolandic regions tumors, 14 of the 35 cases were defined as language areas tumors and 11 of the 35 cases involved both language areas and rolandic regions. Complete resection of enhancing tumor (CRET) was achieved in 30 cases (85.7%), subtotal resection in 5 cases (14.3%), neurological function improved in 34 cases (97.1%) after operation,and 1 case had no improvement compared with that before(2.9%). Thirteen cases without neurological deficit pre-operation, showed transient neurological deficit ,which were recovered about 10 days post-operation, 12 of 22 cases with pre-operative neurologic deficit, improved one week postoperation, 9 of 22 cases with pre-operative neurologic deficit improved one month after operation, the rest 1 case was recurrent with glioblastoma with aggravated hemiplegia symptom after operation, who died of cerebral hernia 2 months later. CONCLUSION Dextroscope virtual reality system can clearly expose and quantify the 3D anatomic relationship of tumors, neural fiber tracts and blood vessels surrounding gliomas near eloquent regions, which is helpful to design the best individualized surgery program, to improve surgical effect.

Abstract
Objective: There is no effective therapy for patients with advanced medullary thyroid carcinoma (MTC). Vandetanib,a novel multitargeted receptor tyrosine kinase inhibitor, has previously shown antitumor activity in phase Ⅱ studies of patients with advanced MTC. This study was to evaluate the efficacy and the safety of vandetanib on advanced MTC. Methods: This study was an open, international multi-center phase Ⅲ clinical trial and the study number was NCT01298323. The single-center study was a sub-group analysis of the international study, which was conducted on 9 pathologically confirmed advanced MTC patients by Cancer Hospital Chinese Academy of Medical Sciences between March 2012 and October 2017. Vandetanib (300 mg) was orally administered daily till death or withdrawal. The efficacy was evaluated according to RECIST criteria and the adverse events were evaluated according to NCI criteria. Results: The objective response rate was 3/9,and the disease control rate was 4/9. The median progression-free survival was 44 months. All patients who had the elevated levels of calcitonin (CTN) and carcino-embryonic antigen (CEA) before treatment began to show the decreases in the level of CTN and CEA after 3 months and later showed again the increases in the levels of both tumor markers with tumor progression. By ROC curve analysis, CTN was of statistically significance(P<0.05, 95%CI 0.558-0.834), but CEA was not(P>0.05). Adverse events were generally mild (grade 1 or 2),including hypertension (9 cases),skin rash (9 cases), and diarrhea (6 cases). Two patients developed grade 3 elevation of serum glutamate pyruvate transaminase and one patient developed grade 3 elevation of drug-related bowel disease. No grade 4 drug-related adverse event occurred. Conclusions: Vandetanib is effective and well tolerated for patients with locally advanced or metastatic MTC who have no chance for surgery. This indicates the increase of CTN is clinically relevant to disease progression, but the number of patients are extremely low, and, therefore further research is needed. Long-term use of vandetanib may cause resistance.

Abstract
OBJECTIVE We tested the hypothesis that cerebellopontine angle (CPA) tumors are associated with a greater incidence of unruptured intracranial aneurysms (IAs). METHODS Patients with intracranial tumors (ITs) undergoing computed tomography angiography and magnetic resonance imaging were enrolled in an observational cohort study that prospectively collected age, sex, hypertension, diabetes, cerebral arteriosclerosis, tumor type, tumor location, hydrocephalus, smoking, alcohol intake, CPA tumor size, cerebral aneurysms, and cerebral arteriosclerosis. Patients with the coexistence of IA and ITwere classified as group II, whereas the others with IT as group I. RESULTS We included 1218 patients with IT for analysis. The incidence of IA was 7.1% (86/1218). A total of 31% of patients with aneurysms had CPA tumors. In a multivariate logistic regression model, a greater incidence of IA was found in female patients (odds ratio [OR] 1.726, 95% confidence interval [CI] 1.050-2.836, P=0.031) and in patients with CPA tumors (OR 3.002, 95% CI 1.822-4.947, P=0.000) after adjustment for tumor type, cerebral arteriosclerosis, and age. In female patients, CPA tumors were a unique independent risk factor of a greater incidence of IA (OR 2.270, 95% CI 1.194-4.317, P=0.012). Furthermore, cerebral arteriosclerosis was a unique independent risk factor of IA in patients with CPA tumors (OR 7.626, 95% CI 2.928-19.860, P=0.000). CONCLUSIONS These data support the hypothesis that CPA tumors are associated with a greater incidence of unruptured IAs, especially in female patients. Cerebral arteriosclerosis contributed to elevated risk of IA in patients with CPA tumors.

Abstract
Vinasse-cured duck was processed by boiling, salting, and vinasse-dry-curing or vinasse-wet-curing. Volatile compounds, moisture contents, reducing sugars, and thiobarbituric acid reactive substances (TBARS) values during processing were determined. Reducing sugars decreased during boiling and increased after vinasse-curing. TBARS values increased throughout the processing. The volatiles of ducks during processing and vinasse-curing agents (dry vinasse and vinasse sauce) were 125 compounds. The first principal component (PC1) belonged to the flavor of cooked duck, whereas the second principal component (PC2) represented the flavor of yellow rice wine. The 66.49 and 29.61% of typical aroma of vinasse-dry-cured product were from dry vinasse and lipid oxidation, respectively, whereas the 75.58 and 21.89% of aroma of vinasse-wet-cured product were from vinasse sauce and lipid oxidation, respectively. Lipid oxidation products increased after boiling, whereas salting promoted their release. Compared with vinasse-wet-cured duck, vinasse-dry-cured product presented richer aroma of lipid oxidation and weaker flavor of vinasse-curing agents. Besides, protein denaturation which was caused by ethanol could influence the retention and release of flavor. In conclusion, two kinds of vinasse-curing methods influenced the characteristic volatiles of products and their generation during processing.

Abstract
Objective: To analysis the treatment effect of the ulnar osteotomy and ring-shaped ligament reconstruction for the treatment of old Monteggia fracture in children by using Meta analyze, and the difference of clinical curative effect was compared in order to provide the basis for the selection of clinical treatment options for old Monteggia fractures in children. Methods: We searched databases such as CNKI, Wanfang database, Medline, PubMed, Embase and Science through computer, at the same time, the references of relevant documents were retrieved manually, and the data processing was carried out by the RevMan5.3 statistical software provided by the Cochrane cooperation network by incorporating the exclusion criteria. The results were obtained and analyzed. Results: A total of 17 standard literature, 438 cases, 224 cases of ulnar osteotomy, 214 cases with ring ligament repair and reconstruction were obtained. The operation scheme, which was mainly based on the lengthening of ulna osteotomy, was superior to the reconstruction of ring ligament reconstruction. The complications and second operation rates of the former was less than that of the latter. Conclusion: The surgical methods for the reconstruction of the ulna osteotomy and the ring-shaped ligament have advantages and disadvantages. The choice of the operative plan for the old Monteggia fracture should be based on the following factors: the time of the old Monteggia fracture formation, the degree of the ulnar and radial deformity and the familiarity of the operative method.

Abstract
Aptamers are single-stranded DNA or RNA which are isolated from synthesized random oligonucleotide library in vitro via systematic evolution of ligands by exponential enrichment (SELEX) and can bind to metal ions, small molecules, carbohydrates, lipids, proteins, and others targets with high affinity and specificity. Aptamers have the advantages of simple preparation, good thermal stability, and low immunogenicity and have great potential in the medical fields such as molecular imaging, biosensing, early diagnosis of diseases, and targeted therapy. Aptamer technology may be useful for early diagnosis and targeted therapy of pediatric cancer, and may avoid the side effects of conventional chemotherapy, such as growth and development disorders and long-term organ dysfunction. This article reviews the latest research advances in the selection and application of aptamers for pediatric cancer.

Abstract
Objective: To evaluate the efficacy and safety of the application of dye-tattooing under ultrasound guidance in preoperative localization of neck recurrences from thyroid cancer. Methods: Between October 2014 to September 2016, 25 patients with 34 lesions were enrolled. There were 22 cases of papillary thyroid carcinoma and three cases of medullary thyroid carcinoma, all of which could not be detected by computed tomography. Surgeons located the recurrent lesions using dye-tattooing under ultrasound guidance along with radiologist three days before the operation. Results: All lesions were successfully located (100%), 32 of which were located directly and two of which were located indirectly. Postoperative pathological examination confirmed 25 metastases of papillary thyroid carcinoma, two metastases of medullary thyroid carcinoma, and seven cases of false positives. The accuracy of ultrasound diagnosis was 79.4%. After 15 months of follow-up, neither tumor residual nor recurrences was detected according to imaging tests. Conclusions: Dye-tattooing under ultrasound guidance represents a reliable and safe method for localization of neck recurrences from thyroid cancer. The cooperation between experienced surgeons and radiologists will be crucial to successful location.

Abstract
We aimed to investigate the biological role of miR-367 in uveal melanoma cell growth and migration, and the underlying mechanism responsible. Quantitative real-time polymerase chain reaction was performed to evaluate miR-367 expression in uveal melanoma tissue samples and cell lines. A miR-367 mimic, miR-367 inhibitor, and negative control oligonucleotide were transfected into these cells to investigate the function of this microRNA. In addition, the role of PTEN in miR-367-mediated uveal melanoma cell growth and migration was evaluated. miR-367 was significantly upregulated in uveal melanoma cells and tissue samples (both P < 0.01). Its inhibition suppressed the proliferation, cell cycle transition, and migration of such cells, and increased levels had the opposite effect. PTEN was confirmed to be a target gene of miR-367. More importantly, co-transfection with a PTEN construct lacking the 3'-untranslated region mitigated miR-367 mimic-induced promotion of uveal melanoma cell proliferation and migration. In summary, miR-367 was found to be upregulated in this malignancy, and may promote uveal melanoma cell proliferation and migration, at least in part by regulating PTEN.

Abstract
Stripe rust, a devastating disease of wheat worldwide, can be controlled by use of diverse wheat resistance resources. To find new quantitative trait loci (QTL) for resistance to stripe rust, Qing Shumai (a Chinese winter wheat landrace possessing slow rusting resistance) was crossed with the susceptible line Mingxian 169. The parents and 276 recombinant inbred lines (RILs) from the cross were evaluated in five environments involving two locations (Gansu and Shandong provinces, China) and four autumn-sown wheat seasons (2008 to 2012). Disease severities on Qing Shumai were lower than 25%, contrasting with approximately 90% on Mingxian 169. The RILs varied in rust intensity in a continuous and monomodal distribution. A bulked segregant analysis approach using 2,344 simple sequence repeat (SSR) markers mapped a major QTL to the long arm of chromosome 6D (hereby designated as QYr.cau-6DL). An SSR marker (gpw5179, https://wheat.pw.usda.gov/GG2/index.shtml ) was identified as being tightly linked with QYr.cau-6DL. Combination between QYr.cau-6DL and the stripe rust-resistance gene Yr18 was examined using 160 F2:3 families of Qing Shumai × RL6058 (a near-isogenic line for Yr18 in the genetic background of the spring wheat Thatcher). The combination elevated the resistance consistently across both winter and spring wheat backgrounds, acting synergistically without undesired epistasis.
