Objective To observe the effects of transdermal acupoint electric stimulation(TEAS)assisting sodium nitroprus-side induced controlled hypotension on serum glucose (Glu),angiotensin Ⅱ (ATⅡ)and superoxide dismutase (SOD),and to inves-tigate the protective effect of TEAS under controlled hypotension anesthesia.Methods 60 cases undergoing elective endoscopy si-nus surgery by adopting sodium nitroprusside induced controlled hypotension under general anaesthesia maintained the mean arterial pressure(MAP)in 50-60 mm Hg and were randomly and equally divided into two groups.The group Ⅰ conducted TEAS,while the group Ⅱ did not conduct TEAS.The controlled hypotension time and surgery time were recorded in the two groups;Glu and ATⅡ values were detected before anesthesia (T0 ),30 min after hypotension (T1 ),hypotension stopping(T2 );SOD was detected at T0 ,T2 ,30 min after hypotension(T3 ).Results The operation time and controlled hypotension continuous time had no statistically significant difference between the two groups(P >0.05).The Glu value in the group Ⅰ had no statistically significant difference a-mong the 3 time points,while which at T1 ,T2 was higher than that at T0 in the group Ⅱ(P <0.05),and which at T1 ,T2 in the group Ⅱ was higher than that in the group Ⅰ (P <0.05);the ATⅡ value at T1 was higher than that at T0 in the group Ⅰ (P <0.05),while which at T1 ,T2 was higher than that at T0 in the group Ⅱ(P >0.05),which at T1 ,T2 in the group Ⅱwas higher than that in the group Ⅰ (P <0.05);the SOD value at T2 was lower than that at T0 in the group Ⅰ,which at T2 ,T3 in the group Ⅱwas lower than that in the group Ⅰ(P <0.05).Conclusion TEAS assisting sodium nitroprusside controlled hypotension can better in-hibit the stress response.

Objective:To investigate the long-term prognosis of liver transplantation (LT) recipients who received grafts from donors aged ≥80 years and the associated risk factors.Methods:Clinical and follow-up data of LT recipients from January 2002 to June 2023 were retrospectively analyzed using the United Network for Organ Sharing (UNOS) database. Donors were categorized into three groups : non-elderly donors (NED, age < 60 years), elderly donors (ED, age 60-79 years), and very elderly donors (VED, age ≥80 years). Propensity score matching (PSM) was used to reduce baseline selection bias among the groups. Survival rates were calculated using the Kaplan-Meier method, and differences among the groups were compared using the Log-Rank test. Univariate and multivariate Cox proportional hazards regression analyses were performed to identify independent risk factors for overall survival (OS) in the VED group. Recipients were further subdivided into three age groups (<50 years, 50-69 years, and ≥70 years) to compare survival outcomes among NED, ED, and VED groups.Results:A total of 115, 089 LT recipients were included, comprising 95, 973 (83.4%) in the NED group, 18, 520 (16.1 %) in the ED group, and 596 (0.5 %) in the VED group. After 3∶3∶1 PSM, each group included 1, 623 recipients for NED and ED, and 541 for VED, with no significant differences in baseline data. The 10-year OS rates for NED, ED, and VED groups were 61.8%, 55.9%, and 47.8%, respectively, and the 10-year graft survival (GS) rates were 61.3 %, 53.8%, and 45.9 %, respectively, with all comparisons showing statistical significance ( P< 0.001). In recipients aged <70 years, the VED group had significantly lower OS and GS rates (49.0% and 47.1 %, respectively ) compared to the NED (63.7 % and 61.8%) and ED (57.7% and 55.2 %) groups ( P< 0.001 ). For recipients aged ≥70 years, there were no significant differences in 10-year OS and GS among the NED (47.2% and 48.7 %), ED (47.0 % and 48.7 %), and VED (40.0 % and 39.2 %) groups ( P= 0.992 and P= 0.996, respectively). Cox regression analysis identified cold ischemia time ≥8 hours ( HR=1.447, 95% CI: 1.088-1.923, P=0.011), pre-transplant ICU dependence ( HR=1.803, 95% CI: 1.176–2.765, P=0.007), and hepatitis B/C virus infection ( HR =1.432, 95% CI: 1.057-1.941, P=0.020) as independent risk factors for OS in the VED group. Conclusions:Liver grafts from VED grafts significantly reduce long-term OS and GS in recipients, except in those aged ≥70 years where prognosis is comparable to recipients of NED and ED grafts.. For the VED group, factors such as cold ischemia time ≥8 hours, pre-transplant ICU dependence, and hepatitis B/C virus infection markedly influence the prognosis.

Objective:To investigate the impact of initial recurrence site on the prognosis of patients with pancreatic cancer after radical operation.Methods:Clinical data of 172 patients who underwent radical resection of pancreatic cancer and were pathologically confirmed as pancreatic ductal adenocarcinoma in Ningbo University Affiliated Lihuili Hospital from January 2015 to June 2021 were analyzed retrospectively. According to the classification of the initial recurrence or metastasis after operation: no recurrence, local recurrence (residual pancreas, mesenteric vein, pancreaticoenterostomy surrounding tissue), liver metastasis, abdominal or retroperitoneum metastasis, multiple site recurrence and other pattern recurrence. The effect on prognosis was analyzed by COX risk ratio model, the overall survival and recurrence-free survival were calculated by Kaplan-Meier, and the survival curve was drawn. Log-rank test was used to compare the survival rate of different recurrence sites and different treatments after recurrence.Results:12 patients had local recurrence, 69 had liver metastasis, 25 had abdominal or retroperitoneal metastasis, 17 had multiple site recurrence, and 5 had other site recurrence and 44 had no recurrence. The median follow-up time was 15.5 months (3-69 months). The median overall survival was 19 months (95% CI 16.273-21.727). The 1- , 3- and 5-year postoperative cumulative survival rate was 71.0%, 27.8% and 20.2%, respectively. Univariate analysis showed that CA125, tumor size, lymph node metastasis, microvascular invasion, tumor differentiation degree, adjuvant chemotherapy, initial recurrence site were significantly correlated with overall survival (All P value <0.05). Multivariate analysis showed that CA125 ≥30 IU/ml ( OR=2.669, P=0.001), microvascular invasion ( OR=1.736, P=0.028), poor tumor differentiation ( OR=1.604, P=0.027), adjuvant chemotherapy ( OR=0.439, P<0.001), initial recurrence site (All P value <0.05) were the independent risk factors for overall survival. The median recurrence-free survival of 172 patients was 9 months (95% CI 7.075-10.925). Univariate analysis showed that CA125, tumor size, lymph node metastasis and microvascular invasion were significantly correlated with recurrence-free survival (All P value <0.05). Multivariate analysis showed that CA125 ( OR=1.640, P=0.026), tumor size ( OR=1.774, P=0.011) and microvascular invasion ( OR=1.563, P=0.034) were the independent risk factors for recurrence-free survival. After surgery, the median survival time of patients with local recurrence, other pattern recurrence, abdominal or retroperitoneal metastasis, multi-site recurrence and liver metastasis was 28, 22, 21, 15 and 14 months, respectively. Among them, the overall survival of patients with postoperative local recurrence was longest, which was significantly longer than that of patients with multi-site recurrence ( P=0.035) and liver metastasis ( P=0.007); the survival of patients with abdominal or retroperitoneal metastasis was also longer than that with liver metastasis ( P=0.005); and all the differences were statistically significant. In 128 patients with recurrence, the median overall survival of 26 patients without adjuvant therapy was 10 months (95% CI 6.877-13.123); the median overall survival of 68 patients with adjuvant chemotherapy was 15 months (95% CI 13.013-16.987); the median overall survival of 34 patients with comprehensive treatment of surgery and radiotherapy was 19 months (95% CI 15.100-22.900), which was significantly higher than the other two groups, and there were significant statistical differences among the three groups ( P<0.001). Conclusions:The initial recurrence site of pancreatic cancer after radical operation is an independent risk factor for overall survival. Compared with local recurrence and abdominal or retroperitoneal metastasis, patients with multi-site recurrence and liver metastasis have a poor prognosis. Comprehensive treatment after recurrence can significantly prolong the overall survival.

Objective To explore the relationship between basic motor skills and social interaction ability in school-age children with moderate autism,and the mediating role of executive function and the realization path.Methods A cross-sectional design was used to investigate 117 school-age children with autism from Sep.to Dec.2020.The level of basic motor skills was assessed by the test of gross motor development(TGMD),the impairment of executive function was assessed by the behavior rating inventory of executive function(BRIEF),and the social disorder was assessed by the social responsive scale-second edition(SRS-2).Pearson correlation analysis was used to explore the interrelationship,and structural equation modeling was applied to explore the path relationship.Results There was a significant negative correlation between the level of basic motor skills and SRS-2 scores(r=-0.312,P＜0.001).There were significant negative correlations between the level of basic motor skills and the BRIEF scores of inhibition(r=-0.336,P＜0.001),switching(r=-0.325,P＜0.001),affective control(r=-0.338,P＜0.001),task initiation(r=-0.240,P=0.009),working memory(r=-0.278,P=0.002),and planning(r=-0.224,P=0.015).The SRS-2 score was positively correlated with the BRIEF scores of inhibition(r=0.378,P＜0.001),switching(r=0.299,P=0.001),affective control(r=0.417,P＜0.001),task initiation(r=0.246,P=0.007),working memory(r=0.409,P＜0.001),and monitoring(r=0.258,P=0.005).Executive function played a complete intermediary role between basic motor skills and social interaction ability(B=-1.912,95％confidence interval:-3.116 to-1.069).Conclusion In school-age children with moderate autism,executive function and social interaction ability change positively with the level of basic motor skills.Basic motor skills can affect social interaction ability through the mediating role of executive function,and inhibition and affective control are important pathways to achieve this.

Chronic fatigue syndrome (CFS) is a common problem in military maritime navigation, which greatly affects the safety of military missions. The use of animal models to carry out research on the mechanism of CFS and treatment measures is a common method. This paper systematically introduced the construction methods of CFS models such as single-factor and multi-factor models, summarized common evaluation indicators of CFS, including behavioral and biochemical indicators, and summed up key characteristics of CFS animal models in military oceanic navigation combined with common causes of CFS in military contexts, such as prolonged continuous work, high-intensity physical activity, sleep deprivation, psychological stress, and extreme environmental conditions. The key characteristics of the animal models included, but not limited to, chronic fatigue, sleep disorders, impaired cognitive function, psychological stress responses, and abnormal biochemical indicators. Furthermore, this article identified future research directions for CFS animal models in military oceanic navigation to enhance the application value of the models and provide robust support for the health protection and disease prevention of military personnel.

Objective: To investigate the features of alveolar bone morphology of mandibular central incisors in high-angle adult females using cone-beam computed tomography (CBCT) and evaluate the influence of aging in these patients. Methods: CBCT and lateral cephalometric images of 142 untreated adult female patients were selected and grouped by facial growth pattern. The number of high-angle cases was increased to 164 to further explore the difference within high-angle adult females who were divided into two groups according to age. The indexes of alveolar bone height and thickness in the lower incisor region and inclination of the lower incisors were measured by Dolphin software. The data was statistically analyzed. Results: Compared with the average-angle group, the high-angle group had a lower alveolar bone attachment level (P < 0.05) and less bone thickness at the root apex level (P < 0.05). The thickness of lingual alveolar bone decreased with labial inclination of the lower incisors in both the high-angle and average-angle groups (r = -0.251, P = 0.025; r = -0.428, P = 0.001, respectively). In hyperdivergent female patients, the middle-aged group had a lower attachment level of alveolar bone than the young group (P < 0.05), but no significant difference in bone thickness at the root apex level (P > 0.05) was found between the two groups Conclusion High-angle adult females had thinner mandibular anterior alveolar bone with significantly lower attachment levels. Aging and inclination of lower incisors influenced bone morphology and should be taken into careful consideration.

Depression is a mental disorder with high morbidity, disability and relapse rates. Ginkgo biloba extract (GBE), a traditional Chinese medicine, has a long history of clinical application in the treatment of cerebral and mental disorders, but the key mechanism remains incompletely understood. Here we showed that GEB exerted anti-depressant effect in mice through regulating gut microbial metabolism. GBE protected against unpredictable mild stress (UMS)-induced despair, anxiety-like and social avoidance behavior in mice without sufficient brain distribution. Fecal microbiome transplantation transmitted, while antibiotic cocktail abrogated the protective effect of GBE. Spatiotemporal bacterial profiling and metabolomics assay revealed a potential involvement of Parasutterella excrementihominis and the bile acid metabolite ursodeoxycholic acid (UDCA) in the effect of GBE. UDCA administration induced depression-like behavior in mice. Together, these findings suggest that GBE acts on gut microbiome-modulated bile acid metabolism to alleviate stress-induced depression.
