Objective:To explore the protective mechanism of tea polyphenols (TP) on mouse oral cancer.Methods:A total of 50 mice were divided into control group, model group, TP group, Selisistat group, TP+ Selisistat group, with 10 mice in each group. The control group was gavaged with physiological saline, while the model group, TP group, Selisistat group, and TP+ Selisistat group were gavaged with 300 mg/L 4-NQO to establish a mouse oral cancer model. Physiological saline, 200 mg/kg TP, 0.01 mg/kg Selisistat, and 200 mg/kg TP+ 0.01 mg/kg Selisistat were gavaged respectively. The weight changes of each group of mice were compared; HE staining was used to observe the morphology of mouse oral tumor tissue; Enzyme linked immunosorbent assay was used to detect the levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in serum; Immunoblotting and immunohistochemistry were used to detect the expression of silencing information regulatory factor (Sirt1) and nuclear factor E2 related factor 2 (Nrf2) proteins in mouse oral tissues.Results:Compared with the control group, the model group mice had a decrease in body weight [(23.19±1.36)g], a decrease in serum SOD level [(91.64±8.75)U/ml], an increase in MDA level [(5.18±0.46)nmol/ml], a decrease in Sirt1 (0.38±0.05) and Nrf2 (0.36±0.05) protein expression in oral tissue, and an increase in Nrf2 acetylation level (0.84±0.11) (all P<0.05). Compared with the model group, the TP group mice had an increase in body weight [(25.28±1.25)g], elevated serum SOD levels [(121.24±10.68)U/ml], decreased MDA levels [(3.89±0.42)nmol/ml], increased expression of Sirt1 (0.61±0.09) and Nrf2 (0.58±0.06) proteins in oral tissue, and decreased Nrf2 protein acetylation levels (0.39±0.05); The Selisistat group mice showed a decrease in body weight [(21.41±1.07)g], a decrease in serum SOD levels [(72.16±7.43)U/ml], an increase in MDA levels [(5.87±0.41)nmol/ml], a decrease in Sirt1 (0.23±0.04) and Nrf2 protein (0.24±0.03) expression in oral tissue, and an increase in Nrf2 acetylation levels (1.12±0.14) ( P<0.05). The body weight [(23.32±1.27)g], serum SOD levels [(92.58±8.13)U/ml], and oral Sirt1 (0.41±0.06) and Nrf2 (0.38±0.05) protein expression in the TP+ Selisistat group mice were higher than those in the Selisistat group, while MDA [(5.11±0.38)nmol/ml] and Nrf2 acetylation levels (0.82±0.09) were lower than those in the Selisistat group (all P<0.05). Conclusions:Tea polyphenols can alleviate oral tissue damage and alleviate oxidative stress in mice with oral cancer, and their mechanism may be related to the upregulation of the Sirt1/Nrf2 pathway.

The International Association for the Study of Lung Cancer (IASLC) recently introduced the ninth edition of the TNM classification for lung cancer. This milestone is supported by a comprehensive database comprising 124 581 lung cancer patients from 75 centers across 25 nations between 2011 and 2019. Following the exclusion of incomplete data, the analysis focused on 87 043 patients. These insights guided the modifications in the ninth edition of the TNM classification for lung cancer. The updated classification now includes a higher representation of Asian patients, particularly showing significant growth among Chinese patients. This revised classification will offer more pertinent benchmarks for the diagnosis and prognostic assessment of lung cancer. This article delves into the database updates, stage adjustments, and rationale behind the IASLC ninth edition of the TNM classification for lung cancer.

ObjectiveTo assess the quality of randomized controlled trials (RCTs) of compound traditional Chinese medicine (TCM) prescriptions in the treatment of nonalcoholic steatohepatitis (NASH), and to provide recommendations for standardizing the design and reporting of RCTs in this field. MethodsDatabases such as PubMed, Web of Science, Embase, the Cochrane Library, CNKI, VIP, and Wanfang Data were searched for RCTs of compound TCM prescriptions in the treatment of NASH published from January 1, 2018 to December 31, 2023, and the articles were screened and assessed based on the Cochrane risk-of-bias assessment tool (RoB 2), the unified standard for clinical trial reporting (CONSORT 2010), and CONSORT-CHM Formulas 2017 for compound TCM prescriptions. ResultsA total of 45 articles were finally included, and most of these studies were rated as high-risk bias by RoB 2.0. The analysis based on the CONSORT control checklist showed a relatively low reporting rate for most of the key items regarding the quality of RCT studies. ConclusionA relatively large risk of bias is observed in the clinical studies on compound TCM prescriptions in the treatment of NASH published in the past six years, which may lead to the poor quality of reporting and evidence. It is suggested that the top-level design of clinical studies should be taken seriously in addition to investigating the advantages of TCM, so as to improve the quality of clinical studies.

Objective To explore the characteristics of response inhibition of military university students during multitasking operation. Methods Repeated measures of ANOVA as well as distribution test were employed to explore how the performance of 127 military university students in Go/No-Go test was affected by simulated driving task. Results The test results of 127 participants showed that there was a interaction between the interference task and the Go trial proportion on the hit rate and false alarm rate,that is,no significant difference was observed between the 60% and 40% of trial proportion without interference task (both P>0.05),but the hit rate and false alarm rate in the 60% trial proportion condition were significantly higher than those in the 40% trial proportion condition under interference task (both P<0.01).In addition,significant main effects of interference task were observed on hit rate,false alarm rate,and discrimination index d' (all P<0.01),that is,the interference task reduced the hit rate and discrimination,but increased the false alarm rate.Moreover,individual differences existed in the discrimination index d' changes,and the participants were divided into easily disturbed group (n=23,18.11%),undisturbed group (n=20,15.75%),and intermediate group (n=84,66.14%) by adding or subtracting 1 standard deviation from the mean of the difference. Conclusion The interference tasks increase the psychological load of military university students during multitasking operation,and impair the response inhibition;and individual differences exist in response inhibition.

Objective To study the process of single stent and double-stent thrombectomy at the Y-shaped bifurcation of the ideal internal carotid artery by finite element simulation, analyze the stent-thrombus-vessel interaction during the thrombectomy process based on the simulation results, and provide guidance for improving the effect of stent thrombectomy at the bifurcation. Methods The CAD software was used to build the model and the finite element analysis software was used to simulate the process of single stent and double-stent thrombectomy. Results Thrombectomy was unsuccessful in single stent model and successful in double-stent model, and the maximum stress of thrombus during embolus retrieval was twice that of single stent, the maximum strain was 1.12 times that of single stent, and the maximum contact pressure on the surface of vessel was approximately twice that of single stent. Conclusions Double Solitaire stents can effectively prevent thrombus displacement at the bifurcation and successfully retrieve the thrombus, but there is a risk of fracture due to the high stress level in the middle section of the thrombus. The contact pressure of the vessel on the anterior artery side is higher during thrombectomy, and the risk of vessel damage is greater. Therefore, it is necessary to optimize the design of the stent-retriever to improve its flexibility.

Background: The newly released Rome criteria in 2016 has a stricter and more precise definition of functional gastrointestinal disorders (FGIDs) when compared with Rome III criteria. The adjustment and improvement of diagnostic criteria by Rome criteria may affect the clinical diagnosis of FGIDs. Aims: To investigate the differences and the similarities between Rome III and Rome criteria in the diagnosis of FGIDs in college students. Methods: The FGIDs database of college students in Zhejiang Province established by our previous research team were further evaluated and analyzed by Rome criteria, and the incidence, psychological symptom score, overlapping of disease of FGIDs were calculated, and compared with Rome III criteria. Results: Of the 1 870 cases in database, 1 025 (54.81%) met Rome criteria of FGIDs; while 1 111 (59.41%) met Rome III criteria, the difference in detection rate was statistically significant (P <0.01). In Rome group, incidences of belching disorders (2.14% vs. 5.83%, P<0.01), irritable bowel syndrome (IBS) (2.78% vs. 6.90%, P<0.01), functional abdominal bloating/distension (1.28% vs. 4.12%, P<0.01) were significantly lower than those in Rome III group, while incidence of functional diarrhea was significantly higher (3.85% vs. 0.70%, P<0.01). Patients met Rome criteria showed a higher score of obsession⁃compulsion, depression and anxiety (P<0.05). Rome criteria caused 33 (25.58%) original IBS patients included in functional diarrhea, and 6 (4.65%) original IBS patients included in function constipation. The diagnosis of functional bowel disease overlapping with other FGIDs (belching disorders, functional dyspepsia) according to Rome III and Rome criteria were statistically different (P<0.01, P<0.05). Conclusions: Rome criteria has a stricter and more accurate definition of FGIDs, reflecting a more accurate psychological and clinical features, and identification of patients who really need treatment, resulting in a more efficient and feasible application in clinical practice and scientific research.

Objective:To explore the effects of interpregnancy interval (IPI) on pregnancy outcomes of subsequent pregnancy.Methods:A multicenter retrospective study was conducted in 21 hospitals in China. Information of age, height, pre-pregnancy weight, IPI, history of diseases, complications of pregnancy, gestational age of delivery, delivery mode, and pregnancy outcomes of the participants were collected by consulting medical records of pregnant women who had two consecutive deliveries in the same hospital during 2011 to 2018. The participants were divided into 4 groups according to IPI:<18 months, 18-23 months, 24-59 months and ≥60 months. According to the WHO′s recommendation, with the IPI of 24-59 months group as a reference, to the effects of IPI on pregnancy outcomes of subsequent pregnancy were analyzed. Stratified analysis was further carried out based on age, history of gestational diabetes mellitus (GDM), macrosomia, and premature delivery, to explore the differences in the effects of IPI on pregnancy outcomes among women with different characteristics.Results:A total of 8 026 women were included in this study. There were 423, 623, 5 512 and 1 468 participants in <18 months group, 18-23 months group, 24-59 months group and ≥60 months group, respectively. (1) The age, pre-pregnancy body mass index (BMI), history of cesarean section, GDM, gestational hypertension and cesarean section delivery rate of <18 months group, 18-23 months group, 24-59 months group and ≥60 months group were gradually increased, and the differences were statistically significant ( P<0.05). (2) After adjusting for potential confounding factors, compared with women in the IPI of 24-59 months group, the risk of premature delivery, premature rupture of membranes, and oligohydramnios were increased by 42% ( OR=1.42, 95% CI: 1.07-1.88, P=0.015), 46% ( OR=1.46, 95% CI: 1.13-1.88, P=0.004), and 64% ( OR=1.64, 95% CI: 1.13-2.38, P=0.009) respectively for women in the IPI≥60 months group. No effects of IPI on other pregnancy outcomes were found in this study ( P>0.05). (3) After stratified by age and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of oligohydramnios for women with advanced age ( OR=2.87, 95% CI: 1.41-5.83, P=0.004); and <18 months could increase the risk of premature rupture of membranes for women under the age of 35 ( OR=1.59, 95% CI: 1.04-2.43, P=0.032). Both the risk of premature rupture of membranes ( OR=1.58, 95% CI: 1.18-2.13, P=0.002) and premature delivery ( OR=1.52, 95% CI: 1.07-2.17, P=0.020) were significantly increased in the IPI≥60 months group. After stratified by history of GDM and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would lead to an increased risk of postpartum hemorrhage for women with a history of GDM ( OR=5.34, 95% CI: 1.45-19.70, P=0.012) and an increased risk of premature rupture of membranes for women without a history of GDM ( OR=1.44, 95% CI: 1.10-1.90, P=0.009). After stratified by history of macrosomia and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months could increase the proportion of cesarean section for women with a history of macrosomia ( OR=4.11, 95% CI: 1.18-14.27, P=0.026) and the risk of premature rupture of membranes for women without a history of macrosomia ( OR=1.46, 95% CI: 1.12-1.89, P=0.005). After stratified by history of premature delivery and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of premature rupture of membranes for women without a history of premature delivery ( OR=1.47, 95% CI: 1.13-1.92, P=0.004). Conclusions:Both IPI≥60 months and <18 months would increase the risk of adverse pregnancy outcomes in the subsequent pregnancy. Healthcare education and consultation should be conducted for women of reproductive age to maintain an appropriate IPI when they plan to pregnant again, to reduce the risk of adverse pregnancy outcomes in the subsequent pregnancy.

Objective? To explore the application methods and effects of early postoperative activities on patients undergoing neurosurgery. Methods? Totally 101 postoperative patients from the Department of Neurosurgery of a Class Ⅲ Grade A hospital in Beijing between June and August 2018 were selected as a control group, while 110 postoperative patients between September and November 2018 were selected as an observation group by convenient sampling. Patients in the control group received routine postoperative care, while patients in the observation group did early post-operative activities. The effects of early off-bed activities such as the time of first early off-bed activity, the frequency of daily off-bed activities and the total time of off-bed activities every day as well as postoperative outcome indicators such as the interval from first off-bed activity to discharge, ability of daily living (ADL) at discharge and hospitalization expenses were compared between the two groups postoperatively. Results? For the effects of early off-bed activities, the time of first off-bed activity and the total time of off-bed activities every day in the observation group were better than those in the control group, and there were statistically significant differences between the two groups (Z/t=-3.300,2.418;P<0.05). After care for early postoperative activities, the median of patients' time of early off-bed activities were reduced from 27.0 h to 24.0 h, and total time of off-bed activities every day were increased from (1.06±0.72) h to (1.27±0.70) h. In terms of patients' postoperative outcomes, the interval from first off-bed activity to discharge, ADL at discharge and hospitalization expenses, there were statistically significant differences between the two groups (Z/t=-3.356,4.428,-3.316;P<0.05). The median of patients' interval from first off-bed activity to discharge were decreased from 55.0 h to 39.3 h. Conclusions? Early postoperative activities can improve the motor ability of neurosurgical patients, shorten their length of hospital stay, and reduce their hospitalization expenses,thus enabling the patients' quicker recovery.
