Objective: To investigate the doseresponse relationship between the risk of elevated blood pressure and body mass index (BMI) in primary and secondary school students in Shibei District, Qingdao, so as to provide a reference for precise interventions of elevated blood pressure. Methods: Statistical analysis was conducted on the health examination data of 92 091 primary and secondary school students in Shibei District, Qingdao, in 2022. Overweight and obesity were assessed using the standards from the Screening for Overweight and Obesity among Schoolaged Children and Adolescents, and blood pressure levels were evaluated using the Reference of Screening for Elevated Blood Pressure among Children and Adolescents Aged 7-18 Years. The relationship between BMI and elevated blood pressure was examined using analysis of variance, Chisquare test, multifactorial Logistic regression, and a combination of restricted cubic spline after data cleaning. Results: Based on the standardized scores under different age and gender, BMI was classified into 5 categories. Compared with the group of BMIZ scores 0-<1, the risk of developing high blood pressure gradually decreased with BMIZ scores (OR=0.55, 0.53, P<0.05). Conversely, the risk of developing high blood pressure increased with increasing BMIZ scores (OR=1.90, 3.71, P<0.05). Stratified analyses showed that BMI was positively associated with elevated blood pressure by gender (male, female), age (aged 7-8, 9-11, 12-14, 15-16), and waisttohip ratio (≤0.83, >0.83) (OR=1.18, 1.19, 1.15, 1.22, 1.19, 1.18, 1.19, 1.18, P<0.01). There were multiplicative interactions between BMI and gender, between BMI and age, between BMI and waisttohip ratio (OR=1.53, 1.08, 2.31, P<0.01). Restricted cubic spline analysis showed that as BMI levels increased, the risk of developing elevated blood pressure showed a nonlinear increasing trend in both the 7yearold and the 10 to 16yearold (χ2=27.56, 10.69, 6.10, 27.26, 18.32, 25.71, 10.53, 6.14, P<0.05). Conclusions The risk of elevated blood pressure in primary and secondary school students increases with BMI, showing a nonlinear doseresponse relationship. The blood pressure should be monitored regularly, and comprehensive and effective measures should be implemented to control elevated blood pressure in children and adolescents.

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

Objective:To investigate the risk factors for hemorrhagic transformation (HT) after intravenous thrombolysis (IVT) in patients with acute ischemic stroke (AIS), and the predictive value of Neutrophil to lymphocyte ratio (NLR).Methods:Consecutive patients with AIS received IVT in Zhengzhou People’s Hospital from January 2021 to December 2022 were retrospectively enrolled. HT was defined as no intracranial hemorrhage was found on the first imaging examination after admission, and new intracranial hemorrhage was found on the imaging examination 24 h after IVT or when symptoms worsened. sHT was defined as HT and the National Institutes of Health Stroke Scale (NIHSS) score increased by ≥4 compared to admission or required surgical treatment such as intubation and decompressive craniectomy. The baseline clinical and laboratory data of the patients were collected, and NLR, lymphocyte to monocyte ratio (LMR), and platelet to neutrophil ratio (PNR) were calculated. Multivariate logistic regression analysis was used to identify the independent predictors of HT and sHT, and receiver operating characteristic (ROC) curve was used to analyze the predictive value of NLR for HT and sHT after IVT. Results:A total of 196 patients were included (age 65.37±13.10 years, 124 males [63.3%]). The median baseline NIHSS score was 4 (interquartile range: 2-10). Twenty patients (10.2%) developed HT, and 12 (6.1%) developed sHT. Univariate analysis showed that there were statistically significant differences in age, baseline NIHSS score, creatinine, NLR, and stroke etiology type between the HT group and the non-HT group (all P<0.05); there were statistically significant differences in age, NLR, PNR, creatinine, baseline NIHSS score, and stroke etiological type between the sHT group and the non-sHT group (all P<0.05). Multivariate logistic regression analysis showed that NLR was an independent predictor of HT (odds ratio [ OR] 1.375, 95% confidence interval [ CI] 1.132-1.670; P=0.001) and sHT ( OR 1.647, 95% CI 1.177-2.304; P=0.004) after IVT. The ROC curve analysis showed that the area under the curve for predicting HT by NLR was 0.683 (95% CI 0.533-0.833; P=0.007), the optimal cutoff value was 5.78, the sensitivity and specificity were 55.0% and 84.1%, respectively. The area under the curve for predicting sHT by NLR was 0.784 (95% CI 0.720-0.839; P=0.001), the optimal cutoff value was 5.94, the sensitivity and specificity were 66.67% and 84.24%, respectively. Conclusions:A higher baseline NLR is associated with an increased risk of HT and sHT after IVT in patients with AIS, and can serve as a biomarker for predicting HT and sHT after IVT.

OBJECTIVE To study the protective effect of phenolic acid components from Salvia deserta Schang on the oxidative stress injury of human renal tubular epithelial cells HK -2 induced by high glucose and high fat . METHODS HK-2 cells were divided into control group ，model group ，canagliflozin group （positive control group ，15 μmol/L），purified product of phenolic acids from S. deserta Schang group （10.8 μg/mL），4 monomers group （salvianic acid ，protocatechuic aldehyde ，caffeic acid，rosmarinic acid ，50 μmol/L）. In addition to the control group ，cell injury model of high glucose and high fat was established in other groups （500 μmol/L palmitic acid+ 30 mmol/L glucose for 48 h）and cultured for 48 h. The cell apoptotic rate ，the contents of malondialdehyde （MDA）and glutathione （GSH），and the activity of superoxide dismutase （SOD）were detected in each group ； the expression levels of nuclear erythroid 2-related factor 2（Nrf2），Kelch-like ECH -associated protein 1（Keap1）protein，heme oxygenase-1（HO-1）and NADH ：quinone acceptor oxidoreductase 1（NQO1）were determined in above 5 groups（except for salvianic acid ，protocatechuic aldehyde ，caffeic acid ）. RESULTS Compared with control group ，the apoptotic rate of HK -2 cells in model group was increased significantly （P＜0.01）；the content of MDA was increased significantly （P＜0.01），while the content of GSH and the activity of SOD were decreased significantly ；protein expressions of Nrf 2，NQO1 and HO -1 2018D01C169） were significantly down -regulated（P＜0.01），while the protein expression of Keap 1 was up -regulated significantly （P＜0.01）. Compared with model group ， the apoptotic rate and the content of MDA were decreased significantly in administration groups（P＜0.01）；the content of GSH in administration groups and the activity of SOD in purified product of phenolic acids group，protocatechuic aldehyde group and rosmarinic acid group were increased significantly （P＜0.01）. The protein expressions of Nrf2，HO-1 and NQO 1 in purified product of phenolic acids group as well as the protein expression of Nrf 2 in rosmarinic acid group were up -regulated significantly （P＜0.01），while the protein expression of Keap 1 was down -regulated significantly in purified product of phenolic acids group and rosmarinic acid group （P＜0.01）. CONCLUSIONS The phenolic acids components from S. deserta Schang can relieve oxidative stress injury of renal tubular epithelial cells induced by high glucose and high fat ，the mechanism of which may be associated with activating Keap 1/Nrf2 signaling pathway and inhibiting oxidative stress response .

OBJECTIVE: To analyze the clinical phenotype and genetic characteristics of a child with Perlman syndrome. METHODS: Genomic DNA was extracted from peripheral blood samples from the patient and her parents. Whole exome sequencing (WES) was carried out to detect potential variant in the proband. Candidate variant was verified by Sanger sequencing. The pathogenicity of candidate variants was evaluated according to the guidelines of the American College of Medical Genetics and Genomics (ACMG). RESULTS: The results of WES showed that the proband has harbored compound heterozygous variants of the DIS3L2 gene, namely c.2109delC and c.1829.c.1830insC, which were respectively inherited from her mother and father. The results were confirmed by Sanger sequencing. Based on the ACMG guidelines, the two novel variants were both predicted to be pathogenic (PVS1+PS2+PM2). CONCLUSION The compound heterozygous variants of the DIS3L2 gene probably underlay the Perlman syndrome in this patient. Above finding has enriched the spectrum of DIS3L2 gene mutations.

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) can speed up the regeneration of future liver remnant (FLR) in short period of time, and offer a chance for surgical resection for patients without sufficient FLR. However, ALPPS still remains controversy due to its high perioperative morbidity and mortality, as well as the uncertain long-term oncological benefits. How to solve these problems is the key to ensure the safety of surgery.This article focus on the indication selection, liver function reserve evaluation and timing to perform the second stage surgery, surgical mode evolution and comparison with portal venous embolization/portal venous ligation+two-stage hepatectomy.

Liver metastases is the most common distant metastases of pancreatic neuroendocrine neoplasms, and it is also one of the main factors affecting the prognosis of patients. With the development of treatment technology and the rise of a multidisciplinary treatment model, the treatment plan for patients with liver metastases has gradually evolved into a comprehensive treatment plan including surgery, intervention, medicine, and radiation therapy. Radical surgery is still the only treatment currently available to cure patients with pancreatic neuroendocrine tumors and liver metastases. Very few selected patients can also benefit from liver transplantation. For most patients who are unable to undergo surgery can choose intervention, medicine and radiation therapy which can improve the patient′s prognosis to a certain extent. Targeted therapy and immunotherapy have good development prospects, and further research is still needed. With multidisciplinary treatment, individualized treatment can help patients obtain the best treatment results.

Objective:To investigate the value of Gd-EOB-DTPA-enhanced MRI in evaluating liver function and predicting the risk of post-hepatoectomy liver failure in patients with major resection of liver cancer.Methods:A total number of 212 patients were included from June 2016 to June 2019 at Department of General Surgery, Peking University Third Hospital with a retrospectively collected data.All patients underwent Gd-EOB-DTPA-enhanced MRI for diagnosis and preoperative evaluation of liver function.There were 135 males and 77 females, with age of (63.1±10.3) years old (range: 18 to 86 years old) . Relative enhancement ratio (RER) of the region of interest on Gd-EOB-DTPA-enhanced MRI was acquired by two independent researcher and then conducted the comparison of RER among the patients with or without post-hepatoectomy liver failure (PHLF) .Preoperative evaluation demonstrated that 141 cases infected by hepatitis virus, 128 cases with hepatitis B alone and 11 cases with hepatitis C alone, 2 cases had both of hepatitis B and C, and all patients were grade A judged by Child-Pugh score. The relationship between RER and PHLF was evaluated by Pearson correlation analysis and the diagnostic value of RER in predicting PHLF was test by receiver operating characteristic curve.Results:PHLF occurred in 42 patients according to ISGLS standard. Among them, 31 cases had level A liver failure, 9 cases had level B liver failure and 2 had level C failure. There was a significant correlation between RER and overall level of PHLF and RER was also significantly associated with severe B to C level of PHLF ( P<0.05) .The further receiver operating characteristics curve analysis showed that the diagnostic accuracy of RER on overall PHLF was 0.818 (sensitivity 72.9%, specificity 83.3%, cut-off value 73.5%, 95 %CI: 0.75 to 0.887) and on severe PHLF was 0.924 (sensitivity 97.0%, specificity 90.9%, cut-off value: 61.5%, 95 %CI: 0.79 to 0.90) . Conclusion:For patients who planned to undergo major resection of liver cancer, preoperative Gd-EOB-DTPA-enhanced MRI can help with the assessment of liver function and predicting the risk for post-hepatectomy liver failure.
