ObjectiveTo explore the mechanism of Buzhong Yiqitang in ameliorating inflammatory injury in autoimmune thyroiditis (AIT) mice based on the Toll-like receptor 4（TLR4）/nuclear transcription factor-kappa B（NF-κB）/absent in melanoma 2（AIM2）inflammasome signaling pathway. MethodThe 120 genetically susceptible 8-week-old NOD.H-2^h4 mice were selected and randomly divided into control group， model group， low， medium and high dose groups of Buzhong Yiqitang （4.78， 9.56， 19.12 g·kg^-1）， and western medicine group （selenium yeast tablets， 3.033×10^-5 g·kg^-1）. The AIT model mice in each group drank ad libitum 0.05% sodium iodide aqueous solution for 8 weeks to establish the AIT model， and the control group drank ad libitum distilled water. Eight weeks later， the mice in each dosing group were divided into groups and gavage. The swelling of thyroid tissue was observed with the naked eye， and the weight of spleen was weighed. The content of serum inflammatory factors interleukin-1β （IL-1β）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α） was measured by enzyme-linked immunosorbent assay （ELISA）， and Real-time PCR was used to detect the expression of HMGB1， TLR4， AIM2， NF-κB p65，apoptosis-associated speck-like protein（ASC），cysteinyl aspartate-specific protease-1（Caspase-1）， IL-1β mRNA. Western blot was used to detect the expression of high motility group protein 1 （HMGB1）， TLR4， AIM2， NF-κB p65， phosphorylation（p）-NF-κB p65， ASC， Caspase-1， and IL-1β proteins in thyroid tissue， and immunofluorescence staining was used to observe the protein expression of HMGB1， AIM2， and NF-κB p65 in thyroid tissue of mice. ResultCompared with the control group， the thyroid tissue of mice in the model group was significantly swollen， the spleen quality was significantly increased， and the expression of HMGB1， TLR4， NF-κB p65， AIM2， ASC， Caspase-1， IL-1β in thyroid tissue was significantly increased （P<0.01）. Compared with the model group， the swelling of thyroid tissue in mice in each dose group of Buzhong Yiqitang was improved， the quality of spleen was significantly reduced， and the expression of HMGB1， TLR4， AIM2， NF-κB p65， p-NF-κB p65， ASC， Caspase-1， IL-1β in thyroid tissue was significantly reduced （P<0.05， P<0.01）. ConclusionBuzhong Yiqitang can effectively improve the inflammatory injury of AIT， and regulating the abnormal activation of the TLR4/NF-κB/AIM2 inflammasome signal pathway may be one of its intervention mechanisms.

AIM:To test and compare the perceptual eye position and fixation stability of adolescents with emmetropia and adolescents with low myopia, investigating the characteristics of the perceptual eye position and fixation stability of adolescents with low myopia.METHODS: Cross-sectional study. A total of 132 adolescents(264 eyes)who visited in the ophthalmology clinic of our hospital from April to December 2023 were randomly selected as the research subjects. Participants were categorized into normal control group(n=45, 90 eyes), simple low myopia group(n=45, 90 eyes)and low myopia with anisometropia group(n=42, 84 eyes)according to their refractive status and were underwent assessments for perceptual eye position and fixation stability.RESULTS: Compared with the normal control group, the static and dynamic horizontal perceptual eye position deviation of the simple low myopia group and the low myopia with anisometropia group were significantly increased(P<0.05). Compared with the simple low myopia group, the static and dynamic horizontal perceptual eye position deviation of the low myopia with anisometropia group were significantly increased(P<0.05). There was no significant difference in static and dynamic vertical perceptual eye position deviation among the three groups(P>0.05); compared with the normal control group, the horizontal and vertical fixation stability of the simple low myopia group and the low myopia with anisometropia group were significantly worse(all P<0.01), but there was no differences in the simple low myopia group and the low myopia with anisometropia group(P >0.05).CONCLUSION: Abnormalities are observed in perceptual eye position and fixation stability function in adolescents with low myopia compared with those adolescents with emmetropia, even at best corrected visual acuity. The occurrence of anisometropia could lead to an increased degree of horizontal perceptual eye position displacement.

Objective To investigate the preparation and evaluation of animal models of depression associated with autoimmune thyroiditis,and to verify the NLRP3/Caspase-1/GSDMD pathway based on this condition.Methods 32 NOD.H-2H4 mice were randomly divided into a normal(N)group,depression(DP)group,autoimmune thyroiditis with depression(AIT+DP)group,autoimmune thyroiditis(AIT)group,with 8 animals in each group.The N group was fed normally,the DP group was subjected to chronic unpredictable mild stress(CUMS)for 5 weeks,the AIT group was given 0.05％sodium iodide water to establish an autoimmune thyroiditis model,and the AIT+DP group was subjected to 5 weeks of CUMS to establish the AIT animal model.We evaluated whether the mouse autoimmune thyroiditis model had been successfully prepared by observing the thyroid tissue structure,lymphocyte infiltration,and serum TGAb and TPOAb levels.Changes in body weight,sugar water preference rate,open field behavior(central quadrant time,central quadrant time proportion,standing rate,frequency of defecation,and hair grooming time),and hippocampal pathological changes were used to evaluate the depression status of the mice.When the model mice met the above-mentioned indicators related to depression and autoimmune thyroiditis,the AIT+DP animal model was considered successfully prepared.Results Compared with the levels in the N group,the AIT group's and AIT+DP group's serum TGAb and TPOAb levels were significantly increased(P＜0.01),and a large number of inflammatory cells had infiltrated the thyroid gland.The central quadrant time and central quadrant time proportion,standing rate,frequency of defecation,and hair grooming time were reduced to varying degrees in the DP group and AIT+DP group.In addition,the numbers of glial cells in the cerebral cortex increased and neuronal cells decreased,accompanied by some nuclear atrophy,and the expression levels of NLRP3,IL-1β,Caspase-1,and GSDMD-N significantly increased,especially in the AIT+DP group(P＜0.01).Conclusions 0.05％sodium iodide water and CUMS create autoimmune thyroiditis with depression model animals that better simulate the external performance and internal index changes of the diseases.These mice can provide an animal model reference for research into autoimmune thyroiditis with depression.

ObjectiveTo determine the trend in diabetes-related death and probability of premature mortality among residents in Yangpu District of Shanghai and provide evidence for the formulation of relevant intervention strategies. MethodsMortality and demographic data were collected among residents in Yangpu District of Shanghai from 2002 to 2020. Statistical analysis was conducted using chi-square test with SPSS 21.0 and Excel 2010. Joinpoint regression was used to determine annual percent change （APC）. The mortality was standardized by utilizing the world standard population in 2000. ResultsA total of 25 091 cases of diabetes-related deaths were reported in Yangpu District， Shanghai from 2002 to 2020. The average annual crude mortality of diabetes-related diseases was 122.10/10⁵， which was 116.13/10⁵ in males and 128.23/10⁵ in females. The difference between males and females in crude mortality was statistically significant （P<0.05）. Moreover， primary causes of diabetes-related deaths were diabetes， cardiovascular and cerebrovascular diseases， and tumors. Among diabetic deaths， peripheral circulatory complications accounted for 50.79%， followed by renal complications （16.05%）. The crude mortality in males， females， and total of diabetes-related diseases showed an upward trend， while the standardized mortality remained stable with an upward trend in male and a downward trend in female. Furthermore， the crude mortality in males， females， and total of diabetes complicated with cardiovascular and cerebrovascular diseases showed an increasing trend. In contrast， both the standardized mortality in males and in total showed an increasing trend， while that in females remained stable. The overall crude mortality of diabetes was on the rise， which was increasing in males and stable in females. The overall standard mortality of diabetes was on the decline， which was increasing in males while declining in females. In addition， the probability of premature mortality caused by diabetes-related diseases， cardiovascular and cerebrovascular diseases complicated with diabetes， and diabetes decreased from 2002 to 2020 with no statistical significance. Males showed an upward trend while females showed a downward trend. ConclusionThe mortality of diabetes-related diseases， cardiovascular and cerebrovascular diseases complicated with diabetes， and diabetes among residents in Yangpu District of Shanghai is on the rise. Similarly， standardized mortality and probability of premature mortality in males for all three diseases are also on the rise. It warrants more attention to the health of male diabetes patients and targeted measures to reduce the disease burden.

Objective:To evaluate A modified Blumgart pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.Methods:The clinical data of 81 patients undergoing laparoscopic pancreaticoduodenectomy in Zhengzhou University Affiliated Cancer Hospital from Jan 2019 to Jan 2022 were retrospectively analyzed. Among them, 26 patients underwent modified Blumgart anastomosis and 55 underwent conventional Blumgart anastomosis.The data of demographics, liver function, pancreatic texture, operational result and complications were compared between the two groups.Results:The preoperative data (body mass index, preoperative albumin, prealbumin, transaminase, total bilirubin) between two groups were comparable ( P>0.05). There was no significant difference in pancreatic texture, pancreatic duct diameter and intraoperative blood loss between the two groups ( P>0.05). The modified group had shorter total operation time ( P<0.05), shorter pancreaticojejunostomy time ( P<0.05), shorter postoperative hospital stay ( P<0.05). The incidence of total pancreatic fistula and biochemical fistula in the modified group were lower than those in the conventional group ( P<0.05). There was no significant difference in the incidence of B/C grade pancreatic fistula and bile leakage, postoperative bleeding, infection and delayed gastric emptying between the two groups ( P>0.05). Conlusions:The modified Blumgart pancreaticojejunostomy during laparoscopic pancreaticoduodenectomy is safe, easy to do and time saving. While the incidence of postoperative pancreatic fistula with clinical significance　and other major complications were similar to traditional Blumgart procedure.

Objective:To explore the related factors of postoperative adjuvant therapy for cervical cancer stagedⅠB1-ⅡA2 [according to 2018 International Federation of Gynecology and Obstetrics (FIGO) staging standard], and to establish a nomogram model to predict the risk of postoperative adjuvant therapy for locally advanced cervical cancer.Methods:A total of 714 patients with cervical squamous cell cancer staged FIGO ⅠB1-ⅡA2 treated by surgery in Anhui Provincial Hospital were selected as the research objects from January 2009 to December 2019, and their clinicopathological data were analyzed. Multiple logistic regression analysis was used to determine the influencing factors, and a nomogram model was established to predict the risk of postoperative adjuvant treatment of cervical cancer. The predictive performance of the model was evaluated with the consistency index (C-index), and the compliance of the model was evaluated with the calibration curve.Results:Univariate analysis suggested that postoperative adjuvant therapy for cervical cancer was associated with gravidity ( χ2=11.506, P=0.001), underlying disease (hypertension or diabetes) ( χ2=7.668, P=0.006), squamous cell cancer antigen (SCC-AG) level ( χ2=19.392, P<0.001), imaging risk factors ( χ2=16.392, P<0.001), FIGO stage ( χ2=25.686, P<0.001), tumor size ( χ2=9.392, P=0.025) and surgical path ( χ2=16.590, P<0.001). Multivariate logistic regression analysis suggested that the number of pregnancy >2 times ( OR=1.951, 95% CI: 1.355-2.808, P<0.001), SCC-Ag ≥1.5 μg/L ( OR=2.021, 95% CI: 1.444-2.829, P<0.001), FIGO stage ⅠB3-ⅡA2 [ⅠB3 ( OR=1.933, 95% CI: 1.139-3.282, P=0.015); ⅡA1 ( OR=2.723, 95% CI: 1.556-4.765, P<0.001); ⅡA2 ( OR=3.159, 95% CI: 1.502-6.646, P=0.002)], with underlying disease (hypertension or diabetes) ( OR=1.867, 95% CI: 1.051-3.318, P=0.033), imaging risk factors ( OR=1.997, 95% CI: 1.127-3.537, P=0.018), without neoadjuvant therapy [preoperative neoadjuvant therapy for 1 cycle ( OR=0.402, 95% CI: 0.207-0.783, P=0.007)] and laparoscopic surgery ( OR=2.177, 95% CI: 1.524-3.112, P<0.001) were independent influencing factors for postoperative adjuvant treatment of cervical cancer. Based on the screened variables, the nomogram model to predict the risk of postoperative adjuvant treatment for cervical cancer has good predictive performance (C-index was 0.702) and compliance. Conclusion:The number of pregnancy >2 times, SCC-Ag ≥1.5 μg/L, FIGO stage ⅠB3-ⅡA2, with underlying disease (hypertension or diabetes), imaging risk factors, without neoadjuvant therapy, and laparoscopic surgery are independent influencing factors for postoperative adjuvant treatment of cervical cancer. A nomogram model has been constructed to predict the risk of postoperative adjuvant therapy for locally advanced cerrical cancer, and it can provide evidence for clinical treatment selection.

Objective:To investigate the predictive value of visceral fat area (VFA) on multiple metabolic risk factors in obese patients undergoing bariatric surgery.Methods:The retrospective case-control study was conducted. The clinical data of 146 obese patients undergoing bariatric surgery in the West China Hospital of Sichuan University from June 2015 to May 2020 were collected. There were 57 males and 89 females, aged (33±9)years, with a range from 15 to 65 years. All patients underwent multi-slice spiral computed tomography (CT) examination, and the total fat area (TFA), VFA and subcutaneous fat area (SFA) were measured. Observation indicators: (1) CT findings of abdominal fat area and patients with multiple metabolic risk factors; (2) receiver operator characteristic(ROC) curve of different clinical indicators for predicting multiple metabolic risk factors; (3) relationship between different VFA and clinicopathological features in patients; (4) analysis of factors influencing multiple metabolic risk factors in patients. Measurement data with normal distribution were expressed as Mean± SD, and comparison between groups was analyzed by independent sample t test. Measurement data with skewed distribution were expressed as M (range) and comparison between groups was analyzed by nonparametric rank sum test. Count data were represented as absolute numbers, and comparison between groups was analyzed using the chi-square test. The ROC curve was used to analyze the predictive value of different clinical indicators for multiple metabolic risk factors in patients. Logistic regression analysis was used for univariate and multivariate analysis. Results:(1) CT findings of abdominal fat area and patients with multiple metabolic risk factors. CT findings of 146 patients showed that VFA was (212±122)cm 2, SFA was (419±147)cm 2, visceral-to-subcutaneous fat ratio (VSR) was 0.60±0.54. The levels of systolic blood pressure (SBP), diastolic blood pressure, fasting blood glucose (FBG), triglyceride and highdensity lipoprotein cholesterol (HDL-C) were (131±16)mmHg(1 mmHg=0.133 kPa), (86±12)mmHg, (6.4±2.5)mmol / L, 4.43 mmol /L(range, 1.23-9.99 mmol/L), (1.5±1.3)mmol/L, respectively. Among the 146 patients, 85 had impaired FBG or diabetes, 82 had hypertension, 139 had high triglyceride, 91 had low serum HDL-C; 128 had multiple metabolic risk factors. (2) ROC curve analysis of different clinical indicators for predicting multiple metabolic risk factors: the ROC curve showed that VFA had better ability to predict or diagnose multiple metabolic risk factors in patients ( hazard ratio=0.617, 95% confidence interval as 0.470-0.764, P<0.05). The cutoff value of VFA was 163.52 cm 2 by calculating Yoden index in ROC curve. (3) Relationship between different VFA and clinicopathological features in patients: according to the cutoff value of 163.52 cm 2 in ROC curve, 146 patients were divided into high VFA group (≥163.52 cm 2) and the low VFA group (<163.52 cm 2), with 49 cases and 97 cases respectively. Cases with hypertension, level of SBP, cases with impaired FBG or diabetes, cases with multiple metabolic risk factors were 64, (134±17)mmHg, 63, 90 for the high VFA group, versus 18, (127±13)mmHg, 22, 38 for the low VFA group; there were significant differences in above indicators between the two groups ( χ2=11.309, t=6.916, χ2=5.380, 6.988, P<0.05). (4) Analysis of factors influencing multiple metabolic risk factors in patients: results of univariate analysis showed that VFA was a related factor for multiple metabolic risk factors in patients ( hazard ratio=3.722, 95% confidence interval as 1.341-10.328, P<0.05). Results of multivariate analysis showed that the VFA≥163.52 cm 2 was an independent rsik factcor or multiple metabolic risk factors in patients ( hazard ratio=5.182, 95% confidence interval as 1.441-18.641, P<0.05). Conclusions:VFA is positively correlated with hypertension, systolic blood pressure, impaired FBG and diabetes. VFA≥163.52 cm 2 is an independent predictor for multiple metabolic risk factors in obese patients undergoing bariatric surgery.

Objective:To explore correlation between RoSCo score and postoperative absolute bed rest time in patients undergoing laparoscopic partial nephrectomy (LPN) .Methods:The imaging data and clinical data of patients undergoing LPN from January 2018 to July 2019 in a Class ⅢGrade A hospital in Suzhou were retrospectively analyzed. RoSCo score was calculated by RENAL score, body mass index (BMI) and Charlson comorbidity index. According to the score, patients were divided into low-risk group (RoSCo score≤4 points) , medium-risk group (RoSCo score of 5 to 6 points) , high-risk group (RoSCo score≥7 points) , and postoperative absolute bed rest time of patients in three groups were collected. The kruskal-Wallis H test of non-parametric test was used to compare the absolute bed rest time of patients in the three groups, and Spearman correlation method was used to analyze the correlation between RoSCo score and postoperative absolute bed rest time. Results:A total of 164 LPN patients were included in the study, including 82 cases in the low-risk group, 65 cases in the medium-risk group and 17 cases in the high-risk group. The median and quartile of absolute bed rest time of all patients was 7 (6, 8) d, including 6 (5, 6) d in the low-risk group, 8 (7, 8) d in the medium-risk group and 11 (11, 12) d in the high-risk group. Postoperative absolute bed rest time of low-risk group, medium-risk group and high-risk group classified by RoSCo score were different, and the differences were statistically significant ( H=112.9, P<0.001) . The pairwise test after using Bonferroni method to correct the significance level found that pairwise comparison of the three groups showed statistically significant differences (all adjusted P<0.001) . RoSCo score was positively correlated with postoperative absolute bed rest time ( r=0.815, P<0.001) . Conclusions:RoSCo score of patients undergoing LPN has a significant positive correlation with postoperative absolute bed rest time. The higher the RoSCo score is, the longer the absolute bed rest time is. Therefore, nursing staff can predict the postoperative absolute bed rest time of LPN patients based on RoSCo score so as to provide a basis for clinical nursing decision.

Objective: To investigate the automatic implicit attitude and explicit stigma of mental illness, and the intervention effectiveness on the stigma of mental illness in college students. Methods: Single category implicit association test(SC-IAT) and questionnaire survey were used to study the degree of implicit and explicit mental illness stigma among 30 college students of Peking University, and investigated the effect of two strategies, education and contact.Data were analyzed by SPSS 22.0 with t-test and variance analysis. Results: The D values of SC-IAT in the three dimensions of cognitive evaluation, emotional response and behavioral tendency of college students were 0.29±0.37, 0.24±0.43, and 0.10±0.43.There was a statistically significant difference between the cognitive evaluation dimension, the emotional response dimension and 0(t=4.069, P<0.01; t=2.925, P<0.01). There was no statistically significant difference between the implicit stigma and the 0 in the behavioral tendency dimension(t=1.423, P=0.167). In the explicit stigma, the mercy dimension score(1.94±0.61) was lower than the median, and the difference was statistically significant(t=-12.286, P<0.01), while the scores of anger dimension(4.62±0.44) and fear dimension (4.55±0.31) were higher than the median(t=13.243, 3.200, both P<0.01). There were no significant differences in the values of implicit and external stigma among pre-intervention, education intervention and after contact(P>0.05). The correct rates of questions "Which of the following situations do you think are considered mentally unhealthy? " and "Which of the following disorders are mental illnesses" (42±13)%, (54±13)%) increased after receiving educational intervention ((49±12)%, (64±13)%), the difference was statistically significant (F=3.682, P<0.05; F=3.576, P<0.05). Conclusion College students have implicit mental illness stigma, educational and contact intervention strategies can help improve college students' understanding of relevant knowledge, and cannot improve the level of implicit stigma of college students on mental illness.
