Objective To compare the long-term survival outcomes of patients with T1-2N0M0 duodenal neuroendocrine tumor (DNET) after endoscopic resection (ER) or surgical resection (SR). Methods Patients diagnosed with T1-2N0M0 DNET between January 1, 2004, and December 31, 2015, were extracted from the SEER database. Kaplan-Meier survival curve and log-rank test were used to compare overall survival (OS) rate and cancer-specific survival (CSS) rate between patients undergoing ER or SR. Propensity score matching (PSM) was used to reduce grouping differences, and multivariate Cox regression was used to analyze factors affecting OS and CSS before and after PSM. Results A total of 656 patients were included, with 457 in ER group and 199 in SR group. Before PSM, there was no significant difference in the 5-year OS rate between the ER and SR groups (88.9% vs 89.6%), but there was a significant difference in the 5-year CSS rate (99.3% vs 96.9%, P=0.017). Before PSM, multivariate Cox regression analysis showed advanced age was an independent risk factor for decreased OS (P<0.001). After PSM, there was no significant difference between the ER group (n=187) and SR group (n=187) in 5-year OS rate (90.2% vs 88.9%) or CSS rate (98.9% vs 96.7%). After PSM, multivariate Cox regression also showed advanced age was an independent risk factor for decreased OS, while resection method was not an independent factor for OS or CSS. Conclusions There is no significant difference in OS or CSS after endoscopic treatment and surgical treatments for patients with T1-2N0M0 DNET, and advanced age is an independent factor for OS.

OBJECTIVE To explore the effect and mechanism of Zhiqiao gancao decoction (ZQGCD) on pathological angiogenesis of degenerative intervertebral disc. METHODS The rats were randomly divided into sham operation group (normal saline), model group (normal saline), hypoxia inducible factor-1α (HIF-1α) inhibitor (YC-1) group [2 mg/(kg·d), tail vein injection], and ZQGCD low-dose, medium-dose and high-dose groups [3.06, 6.12, 12.24 g/(kg·d)], with 8 rats in each group. Except for sham operation group, lumbar disc degeneration model of rat was constructed in all other groups. After modeling, they were given relevant medicine once a day, for consecutive 3 weeks. After the last medication, pathological changes and angiogenesis of the intervertebral disc tissue in rats were observed; the levels of inflammatory factors [interleukin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α)] and the expressions of angiogenesis-related proteins [HIF-1α, vascular endothelial growth factor (VEGF), VEGF receptor 2 (VEGFR2), angiotensin 1(Ang 1), Ang 2] in the com intervertebral disc tissue in rats were all determined. In cell experiment, the primary nucleus pulposus cells were isolated and cultured from rats, and cellular degeneration was induced using 50 ng/mL TNF-α. The cells were divided into blank control group (10% blank control serum), TNF-α group (10% blank control serum), YC-1 group (10% blank control serum+0.2 mmol/L YC-1), and 5%, 10%, 15% drug-containing serum group (5%, 10%, 15% drug-containing serum). After 24 hours of intervention, the nucleus pulposus cells were co-cultured with HUVEC. The expressions of Collagen Ⅱ, matrix metalloproteinase-3 (MMP-3) in nucleus pulposus cells were detected. HUVEC proliferation, migration and tube forming ability were detected, and the expression levels of the HIF-1α/VEGF/Ang signal axis and angiogenesis- related proteins (add MMP-2, MMP-9) in HUVEC were detected. RESULTS Animal experiments had shown that compared with model group, the positive expression of CD31 in the intervertebral disc tissues of rats in each drug group was down-regulated (P< 0.05), the levels of inflammatory factors and angiogenesis-related proteins were decreased significantly (P<0.05), and the pathological changes in the intervertebral disc were alleviated. Cell experiments had shown that compared with TNF-α group, the expression of Collagen Ⅱ in nucleus pulposus cells of all drug groups was significantly up-regulated (P<0.05), and the expression of MMP-3 was significantly down-regulated (P<0.05); the proliferation, migration and tubulogenesis of HUVEC were significantly weakened (P<0.05). The mRNA and protein expressions of HIF-1α, VEGF, Ang 2 as well as the expression of angiogenesis-related proteins (except for the expression of Ang 2 mRNA and HIF-1α, VEGFR2, Ang 2 protein in 5% drug- containing serum group) were significantly down-regulated (P<0.05). CONCLUSIONS ZQGCD may inhibit the HIF-1α/VEGF/ Ang signal axis to weaken the angiogenic ability of vascular endothelial cells, improve pathological angiogenesis in the intervertebral disc, and delay the degeneration of the intervertebral disc.

AIM: To detect the expression of P53 and mTOR in pterygium tissues and healthy conjunctival tissues, and to explore the relationship between the expression of P53 and mTOR, and the relationship between the expression of P53 and mTOR and the important clinical features of pterygium.METHODS: The surgical specimens of 43 patients(43 eyes)who underwent pterygium excision and autologous conjunctival transplantation in the First Affiliated Hospital of Shihezi University from November 2022 to May 2023 were collected. Healthy conjunctiva group was selected from the healthy conjunctival tissue that originated from the temporal conjunctiva of 13 patients. Totally 10 pterygium specimens and 6 normal conjunctival specimens were selected and the qPCR was used to detect the mRNA expression levels of P53 and mTOR in pterygium and normal conjunctival tissues. Another 33 cases of pterygium and 7 cases of normal conjunctival tissues were collected and the expression of P53 and mTOR in pterygium and normal conjunctival tissues were detected by immunohistochemistry. IPP6.0 software was used to calculate the average optical density, the correlation between the expression levels of P53 and mTOR, and the correlation between the expression levels of P53 and mTOR and the important clinical features of pterygium were analyzed.RESULTS: According to qPCR results, the mRNA expression levels of TP53 and mTOR in the pterygium group were significantly higher than those in the healthy conjunctiva group(all P<0.05). According to the immunohistochemical staining results, the expression levels of P53 and mTOR proteins in the pterygium group were significantly higher than those in the healthy conjunctiva group(P<0.05). The expression of P53 was positively correlated with the expression of mTOR(r=0.417, P<0.05). The expression of P53 in the group of outdoor activity time > 3 h was higher than that in the group of outdoor activity time ≤3 h(P<0.05). The expression of P53 in the group of pterygium head invasive limbal distance > 2 mm was higher than that in the group of pterygium head invasive limbal distance ≤2 mm(P<0.05). There was no difference in the expression of pterygium between the two groups of patients aged > 40 years and ≤40 years(P>0.05). There was no significant difference in the expression of mTOR between the groups of outdoor activity time > 3 h and ≤3 h, the group of pterygium head invasion distance > 2 mm and ≤2 mm, and the group of > 40 years old and ≤40 years old(all P>0.05). The expression of P53 was positively correlated with the duration of outdoor activities(r=0.484, P<0.01)and the distance of limbal invasion(r=0.479, P<0.01). The expression of mTOR was not correlated with age, duration of outdoor activities, and distance of limbus invasion(all P>0.05).CONCLUSION: The overexpression of P53 and mTOR in pterygium showed a positive correlation, suggesting that the abnormal expression of P53 and mTOR may play a role in the pathogenesis of pterygium, which provides an experimental basis for further exploring the pathogenesis of pterygium; the expression of P53 is positively correlated with the time of outdoor activities and the distance of pterygium invasion. The P53 plays a role in evaluating the severity of pterygium, and provides new ideas for the clinical diagnosis and treatment of pterygium.

Purpose::The toughest challenge in pedestrian traffic accident identification lies in ascertaining injury manners. This study aimed to systematically simulate and parameterize 3 types of craniocerebral injury including impact injury, fall injury, and run-over injury, to compare the injury response outcomes of different injury manners.Methods::Based on the total human model for safety (THUMS) and its enhanced human model THUMS-hollow structures, a total of 84 simulations with 3 injury manners, different loading directions, and loading velocities were conducted. Von Mises stress, intracranial pressure, maximum principal strain, cumulative strain damage measure, shear stress, and cranial strain were employed to analyze the injury response of all areas of the brain. To examine the association between injury conditions and injury consequences, correlation analysis, principal component analysis, linear regression, and stepwise linear regression were utilized.Results::There is a significant correlation observed between each criterion of skull and brain injury ( p < 0.01 in all Pearson correlation analysis results). A 2-phase increase of cranio-cerebral stress and strain as impact speed increases. In high-speed impact (> 40 km/h), the Von Mises stress on the skull was with a high possibility exceed the threshold for skull fracture (100 MPa). When falling and making temporal and occipital contact with the ground, the opposite side of the impacted area experiences higher frequency stress concentration than contact at other conditions. Run-over injuries tend to have a more comprehensive craniocerebral injury, with greater overall deformation due to more adequate kinetic energy conduction. The mean value of maximum principal strain of brain and Von Mises stress of cranium at run-over condition are 1.39 and 403.8 MPa, while they were 1.31, 94.11 MPa and 0.64, 120.5 MPa for the impact and fall conditions, respectively. The impact velocity also plays a significant role in craniocerebral injury in impact and fall loading conditions (the p of all F-test < 0.05). A regression equation of the craniocerebral injury manners in pedestrian accidents was established. Conclusion::The study distinguished the craniocerebral injuries caused in different manners, elucidated the biomechanical mechanisms of craniocerebral injury, and provided a biomechanical foundation for the identification of craniocerebral injury in legal contexts.
