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.

Ureteral stenosis and bladder contracture after radiotherapy for cervical cancer are challenging issues in urology. Ileal ureteroplasty combined with ileal bladder augmentation is a potential method to improve hydronephrosis and voiding function of patients, however, the surgical procedure is complex, with high surgical risks and numerous intraoperative and postoperative complications, which have hindered the widespread application of this surgical technique. This article introduces our hospital's experience through a typical surgical case. During the surgery, ileal substitution for bilateral ureters was performed in combination with ileal " N-shaped" augmentation. Two weeks after the surgery, the single-J stent was removed, and the urinary catheter was removed three weeks after the surgery. The patient achieved voluntary urination control with smooth voiding. Follow-up examinations at 3 months and 18 months postoperatively showed no hydronephrosis in the bilateral ureters, normal renal function, and a significantly expanded bladder capacity.

Background::Evidence indicates that low muscle strength is associated with an increased cardiovascular diseases (CVDs) risk. However, the association between muscle strength changes based on repeated measurements and CVD incidence remains unclear.Methods::The study used data from the China Health and Retirement Longitudinal Study in 2011 (Wave 1), 2013 (Wave 2), 2015 (Wave 3), and 2018 (Wave 4). Low muscle strength was defined as handgrip strength <28 kg for men or <18 kg for women, or chair-rising time ≥12 s. Based on changes in muscle strength from Waves 1 to 2, participants were categorized into four groups of Normal-Normal, Low-Normal, Normal-Low, and Low-Low. CVD events, including heart disease and stroke, were recorded using a self-reported questionnaire during Waves 3 and 4 visits. Cox proportional hazards models were used to investigate the association between muscle strength changes and CVD incidence after multivariable adjustments. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated with the Normal-Normal group as the reference.Results::A total of 1164 CVD cases were identified among 6608 participants. Compared to participants with sustained normal muscle strength, the CVD risks increased progressively across groups of the Low-Normal (HR = 1.20, 95% CI: 1.01-1.43), the Normal-Low (HR = 1.35, 95% CI: 1.14-1.60), and the Low-Low (HR = 1.76, 95% CI: 1.49-2.07). Similar patterns were observed for the significant associations between muscle strength status and the incidence risks of heart disease and stroke. Subgroup analyses showed that the significant associations between CVD and muscle strength changes were consistent across age, sex, and body mass index (BMI) categories.Conclusions::The study found that muscle strength changes were associated with CVD risk. This suggests that continuous tracking of muscle status may be helpful in screening cardiovascular risk.

Objective To explore the possible mechanism of emodin in inhibiting proliferation,migration,and invasion of AGS cells and in suppressing the expressions of YAP1 and FOXD1.Methods Normal gastric cell GES-1 and gastric cancer cell AGS were cultured with different concentrations of emodin.CCK8 test,scratch test and Transwell assay were used to verify changes in the biological phenotype of AGS cells.TCGA database was applied to analyze expressions of HK2,YAP1 and FOXD1 in gastric cancer tissues and normal gastric tissues.Western blotting method was used to detect the impacts of emodin on HK2,YAP1 and FOXD1 proteins in AGS cells.Exogenous pyruvic acid was added to verify the changes in YAP1 and FOXD1.Results The IC50 of emodin was significantly higher in GES-1 cells than in AGS cells(P<0.05).CCK8 proliferation test,scratch test,and Transwell assay showed that emodin significantly inhibited the biological abilities of AGS(P<0.05 for comparisons).Analysis on the TCGA bioinformatics database found that the expression of key enzymes HK2 in the glycolysis pathway and oncogenes YAP1 and FOXD1 was significantly higher in gastric cancer tissues than in normal gastric tissues(P<0.05 for comparisons).Emodin significantly inhibited the protein expressions of key glycolytic enzymes HK2 and oncogenes YAP1 and FOXD1(P<0.05 for comparisons).With supplement of exogenous glycolytic metabolite pyruvate,the protein expressions of oncogenes YAP1 and FOXD1 significantly increased(P<0.05 for comparisons).Conclusions Emodin has a significant pharmacological inhibitory effect on gastric cancer AGS cells,markedly suppressing their biological phenotype.Emodin not only significantly inhibits the key enzyme HK2 in glycolysis metabolism,but also the protein expressions of oncogenes YAP1 and FOXD1.With the addition of exogenous pyruvate to enhance the glycolytic metabolic pathway,the protein expressions of oncogenes YAP1 and FOXD1 significantly increased.The above results suggest a close association of YAP1 and FOXD1 with glycolytic metabolism.Emodin may inhibit oncogenes YAP1 and FOXD1 through the glycolytic metabolism of gastric cancer AGS cells.

Background Perfluoroalkyl substances (PFASs) are classified as persistent organic pollutants and have been widely detected in human. Studies investigating the associations between PFASs exposure and estimated glomerular filtration rate (eGFR) yielded inconsistent results, and little is known about the effects of PFASs on eGFR in population without kidney disease. Objective To explore the associations of exposure to PFASs with eGFR and renal dysfunction in population without kidney disease. Methods A total of 609 participants with an eGFR > 60 mL·min⁻¹·1.73 m⁻² and without renal impairment matched for sex and age (1∶1) were recruited from endocrinology department and medical examination center of two hospitals in Tianjin, China, from April 2021 to March 2022. Each subject was interviewed using a structured questionnaire to collect information about sex, age, height, weight, disease history, smoking, alcohol intake, etc. Clinical parameters were obtained from medical record, such as fasting blood glucose (FBG), creatinine (Cre), total cholesterol (TC), and triglyceride (TG). Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured by professionals using standard methods. The serum concentrations of PFASs were determined by liquid chromatography/mass spectrometry. Multivariable linear and logistic regression models were performed to evaluate the associations of PFASs exposure with eGFR and renal dysfunction, respectively. Subgroup analyses stratified by age and sex were also performed to assess the modified effects of covariates on the associations of PFASs exposure with eGFR. Results There were 283 males, accounting for 46.5% of the total population. The mean age of the participants was (56.86±12.47) years, and the average body mass index (BMI) was (25.59±3.84) kg·m⁻². Perfluoro-n-octanoic acid (PFOA), perfluorohexane sulfonic acid (PFHxS), perfluorooctane sulfonic acid (PFOS), perfluoro-n-nonanoic acid (PFNA), perfluoro-n-decanoic acid (PFDA), perfluoro-n-undecanoic acid (PFUnDA), sodium 1H, 1H, 2H, 2H-perfluoro-1-octanesulfonate (6:2 FTS), and perfluoropentane sulfonic acid (PFPeS) were positive in more than 75% of serum samples, and the corresponding median concentrations were 9.50, 1.67, 17.22, 1.86, 1.41, 0.78, 0.42, and 0.43 μg·L⁻¹, respectively. After full adjustments of sex, age, BMI, hypertension, diabetes, TC, TG, smoking, and drinking, the linear regression models showed that log₂-transformed PFHxS concentration was negatively associated with eGFR (b=−1.160, 95%CI: −2.280, −0.410). Compared with the lowest exposure tertile, the estimated change of eGFR in the highest tertile for PFHxS was significantly decreased (b=−2.471, 95%CI: −4.574, −0.368). Furthermore, compared with males, the negative association of PFHxS with eGFR was strengthened among females (female: b=−1.281, 95%CI: −2.388, −0.174; male: b=−0.781, 95%CI: −2.823, 1.261, P_interaction=0.043). Conclusion A significant negative association between serum PFHxS and eGFR is observed in the sampled population without kidney disease, and females are more susceptible to PFASs exposure than the males.

There are few reports on laparoscopic repair of traumatic atresia of bladder neck. In this study, three patients with traumatic atresia of bladder neck were repaired by laparoscopic surgery, and the surgery was successfully completed. During postoperative follow-up, the patients had smooth urination, no urinary incontinence and sexual function damage, and laparoscopic surgery was effective in repairing traumatic atresia of bladder neck.

Objective:To determine the adverse effects of continuous circulatory support on liver and kidney function in experimental animals using left ventricular assist devices (LVAD).Methods:Six healthy experimental sheep were selected and implanted with HeartCon type LVAD. The liver and kidney indexes of experimental sheep before and 70 days after operation were detected, including urea (UREA), creatinine (CREA), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBIL), and the functional changes of liver and kidney were evaluated.Results:The preoperative levels of UREA, CREA, ALT, AST and TBIL in the six experimental sheep were (4.60±1.51) mmol/L, (94.80±23.10) μmol/L, (16.20±6.87) U/L, (82.60±17.33) U/L, and (0.52±0.25) μmol/L, respectively. Compared with the indexes before the LVAD implantation, there was no significant change in CREA levels in experimental sheep after the implantation (all P>0.05). After the implantation, the levels of UREA, ALT, AST and TBIL increased to varying degrees within 1 to 14 days after the implantation. At the end of the study, the levels of UREA, ALT, AST and TBIL have returned to the preoperative levels, and the differences were not statistically significant (all P>0.05). Conclusions:Within the 70 days of continuous circulatory support with HeartCon-type LVAD, no evidence of adverse effects of continuous flow LVAD on the liver and kidney function of experimental animals was found. HeartCon-type LVADs are able to provide adequate circulatory support to maintain proper end-organ function.

Objective:To analyze the molecular characteristics of dengue virus (DENV) strains circulating in Shantou city in 2018 and 2019 for elucidating the reasons causing strikingly different dengue fever epidemics during the two years and understanding the transmission characteristics and routes of DENV, and to provide reference for the prevention and control of dengue fever.Methods:Detection of viral nucleic acid contents and amplification and sequencing of E gene were carried out on 872 samples positive for DENV acid in 2018 and 2019. Phylogenetic trees were constructed based on the E gene sequences to analyze the homology of DENV strains. The sources and transmission routes of the strains were also analyzed. Results:A total of 99 sequences of DENV E gene were acquired, including 68 DENV-1 sequences and 31 DENV-2 sequences. The cases of dengue fever were sporadic in 2018. Phylogenetic tree showed the strains isolated in 2018 were from multi-sources and closely related to those found in Guangzhou city and Southeast Asia area. Dengue fever outbreaks occurred in 2019 and most of the prevalent strains were from a single source, which was speculated to be Cambodia. Conclusions:Dengue fever in Shantou city was mainly caused by imported strains of the same year rather than by local strains in previous years. DENV strains in Shantou might be traced back to Southeast Asia area and transmitted to Shantou through many routes.

It is unknown whether the famous sex-related difference in emotion processing is accounted for by biological sex, gender role, or their interaction. To clarify the issue, in Study 1 we recorded event-related potentials in response to negative and positive images of diverse intensities when 47 masculine (26 males) and 47 feminine (22 males) subjects performed a non-emotional task. The occipital P1 and N1 amplitudes were larger in women than in men, while feminine subjects showed larger N1 amplitudes than masculine subjects, regardless of sex. Moreover, feminine subjects showed enhanced frontocentral N2 (210–270 ms) amplitudes for highly and mildly negative than for neutral stimuli, while masculine subjects showed an emotion effect only for highly negative stimuli. The feminine-specific effect for mildly negative stimuli was positively correlated to the feminine score, and this correlation was located to the anterior cingulate and the superior and medial frontal gyri. Furthermore, feminine but not masculine subjects showed enhanced parietal P3 (330–560 ms) amplitudes for highly and mildly positive than for neutral stimuli, an effect positively related to the feminine score and localized to the precuneus, posterior cingulate, and superior temporal gyrus. Machine learning analyses verified that single-trial N2 and P3 amplitudes of feminine subjects reliably discriminated the intensity of negative and positive stimuli, respectively. For ecological considerations, in Study 2 we used an observational approach (n = 300) and confirmed that feminine gender role, rather than biological sex, predicted individual differences in daily experience of emotion-related psychopathological symptoms. These findings provide solid evidence for the critical impact of gender role rather than sex on emotional susceptibility.

Objective: To explore the biodistribution and quantitative value of ¹⁸F-Flurpiridaz in mini-swine, and compare with ¹³N-NH₃·H₂O. Methods: Ten Bama mini-swine were divided into normal group and myocardial infarction group (n=5 in each group). Normal group was not treated and myocardial infarction group was modeled by thoracotomy and coronary artery ligation. Both groups were preceded by ¹³N-NH₃·H₂O imaging, followed by ¹⁸F-Flurpiridaz imaging (time interval >40 min). Injection dosage of 2 tracers was the same (185-370 MBq). ¹⁸F-Flurpiridaz whole-body PET/CT imaging was also performed in normal group. Biological distribution of ¹⁸F-Flurpiridaz was observed, and the ratio of radioactive uptake of ¹⁸F-Flurpiridaz between myocardium and adjacent tissues or organs was calculated. Image quality score and rest myocardial blood flow (rMBF) of 2 imaging tracers in normal group were measured and compared. MPI image quality score, cardiac function parameters such as summed rest score (SRS), myocardial infarction area percentage, total perfusion defect (TPD), and left ventricular ejection fraction (LVEF) of 2 imaging tracers were compared in myocardial infarction group. Data was analyzed by paired t test. Results: In normal group, ¹⁸F-Flurpiridaz in the myocardium was clearly observed, with high radioactive uptake maintaining within 2 h postinjection. The radioactivity count ratios of left ventricular myocardium to cardiac pool, the lungs and liver were high (5.19-12.87, 4.17-50.51, 2.08-6.92). The quality of ¹⁸F-Flurpiridaz MPI images in both groups was excellent (10/10). The rMBF (ml·g^-1·min^-1) in different regions of left ventricle measured by ¹⁸F-Flurpiridaz and ¹³N-NH₃·H₂O imaging were not significantly different (left anterior descending: 0.98±0.06 vs 0.92±0.13; left circumflex: 0.98±0.05 vs 0.88±0.12; right coronary artery: 0.95±0.07 vs 0.88±0.15; left ventricle: 0.96±0.07 vs 0.90±0.13; t values: from -1.70 to -0.90, all P>0.05). There was no significant difference in SRS, myocardial infarction area percentage, TPD, rMBF or LVEF between ¹⁸F-Flurpiridaz and ¹³N-NH₃·H₂O (SRS: 10.6±4.1 vs 9.2±4.6; myocardial infarction area percentage: (15.2±9.0)% vs (12.6±6.6)%; TPD: (11.6±6.3)% vs (9.6±3.9)%; LVEF: (68.6±11.1)% vs (71.4±11.3)%; t values: -2.33-2.75, all P>0.05). Conclusions Comparing with ¹³N-NH₃·H₂O, ¹⁸F-Flurpiridaz has the advantages of good MPI image quality, accurate measurement of cardiac function parameters and quantitative potential of myocardial blood flow, which make it as a promising positron myocardial perfusion imaging agent.
