ABSTRACT
Pupil size, as a window into the minds of others, plays a crucial role in social interaction. While previous studies have focused on the influence of non-social factors, such as the physical properties of stimuli, on pupil diameter, recent research has emphasized the significant connection between social information processing and pupil size. In this comprehensive review, we aim to explore how the processing of social stimuli (e.g., face, biological motion) and their emotional characteristics affect pupil size. In essence, pupil size is believed to reflect an individual’s perception of social stimuli. It goes beyond simple physical properties and encompasses the processing of complex social information, including social contexts and interactions. The modulation of pupil size in response to social stimuli is believed to be driven by two key mechanisms: emotional arousal and social attention. When individuals encounter emotionally charged social cues, their pupils tend to dilate, indicating heightened emotional engagement. Similarly, the dilation of pupils when individuals focus on specific social cues suggests an increased allocation of cognitive resources to process relevant social information. Furthermore, the connection between pupil size and social information processing has provided intriguing findings in individuals with autism spectrum disorder (ASD). Known for their significant social deficits, individuals with ASD exhibited abnormal pupillary responses when presented with social stimuli. These findings raise the possibility of utilizing pupillary responses as a potential index for identifying individuals with ASD at a relatively younger age. Moreover, the incorporation of pupillary response measurements in the diagnosis holds great promise in transcending the limitations of the minimum diagnostic age. This can have important implications both in terms of theoretical understanding and practical applications related to the diagnosis and intervention of ASD.
ABSTRACT
Many studies have confirmed that gut microbiota plays a pivotal role in human health. It affects multiple organ systems other than the digestive tract. The bidirectional communication between the microbiota and the human body is finely orchestrated by different systems, including the nervous, immune, and endocrine systems. Moreover, intestinal flora imbalance plays an important role in the occurrence and development of ocular diseases such as glaucoma, uveitis, diabetic retinopathy, and age-related macular degeneration. Multiple microbiota and related metabolite(involving both microbe and host)both impact ocular diseases in animal models and demonstrate striking associations in clinical studies. Therefore, modulation of gut microbiota and metabolite may be beneficial for the maintenance of ocular homeostasis and the treatment of related ocular diseases. This article reviews the recent progress in the studies on relationship between intestinal microorganisms and several common ocular diseases, providing therapeutic targets for potential translational investigations within this research field.
ABSTRACT
Pancreatic cancer is a malignant tumor of digestive system with poor prognosis,and surgical resection is still the only hope for a radical cure. Although the current consensus and guidelines describe in detail the standard and extended range of lymph node dissection,the selection of specific range of lymph node dissection and its impact on prognosis are still controversial. Current studies have not only proposed some improved extent of lymph node dissection, such as total mesopancreas excision and Heidelberg triangle dissection, but also suggested different extent of lymph node dissection for ventral and dorsal pancreatic head cancer. In addition, the prognosis of pancreatic head cancer in uncinate process and non-uncinate process is different after para-aortic lymph node dissection, which is worthy of further study. Neoadjuvant therapy or conversion therapy provides more surgical opportunities for patients with pancreatic cancer. For these patients, Heidelberg triangle dissection has potential value in improving prognosis. This paper summarizes the exploration and latest progress of standard and extended lymph node dissection, lymph node dissection of specific site of pancreatic head cancer and the extent of lymph node dissection after neoadjuvant/transformation therapy in recent years.

Melatonin receptor 1B (MT2, encoded by the MTNR1B gene), a high-affinity receptor for melatonin, is associated with glucose homeostasis including glucose uptake and transport. The rs10830963 variant in the MTNR1B gene is linked to glucose metabolism disorders including gestational diabetes mellitus (GDM); however, the relationship between MT2-mediated melatonin signaling and a high birth weight of GDM infants from maternal glucose abnormality remains poorly understood. This article aims to investigate the relationship between rs10830963 variants and GDM development, as well as the effects of MT2 receptor on glucose uptake and transport in trophoblasts. TaqMan-MGB (minor groove binder) probe quantitative real-time polymerase chain reaction (qPCR) assays were used for rs10930963 genotyping. MT2 expression in the placenta of GDM and normal pregnant women was detected by immunofluorescence, western blot, and qPCR. The relationship between MT2 and glucose transporters (GLUTs) or peroxisome proliferator-activated receptor γ (PPARγ) was established by western blot, and glucose consumption of trophoblasts was measured by a glucose assay kit. The results showed that the genotype and allele frequencies of rs10830963 were significantly different between GDM and normal pregnant women (P<0.05). The fasting, 1-h and 2-h plasma glucose levels of G-allele carriers were significantly higher than those of C-allele carriers (P<0.05). Besides, the protein and messenger RNA (mRNA) expression of MT2 in the placenta of GDM was significantly higher than that of normal pregnant women (P<0.05). Melatonin could stimulate glucose uptake and GLUT4 and PPARγ protein expression in trophoblasts, which could be attenuated by MT2 receptor knockdown. In conclusion, the rs10830963 variant was associated with an increased risk of GDM. The MT2 receptor is essential for melatonin to raise glucose uptake and transport, which may be mediated by PPARγ.

OBJECTIVE@#To screen the risk factors for death in patients with nasopharyngeal carcinoma (NPC) using artificial intelligence (AI) technology and establish a risk prediction model.@*METHODS@#The clinical data of NPC patients obtained from SEER database (1973-2015). The patients were randomly divided into model building and verification group at a 7∶3 ratio. Based on the data in the model building group, R software was used to identify the risk factors for death in NPC patients using 4 AI algorithms, namely eXtreme Gradient Boosting (XGBoost), Decision Tree (DT), Least absolute shrinkage and selection operator (LASSO) and random forest (RF), and a risk prediction model was constructed based on the risk factor identified. The C-Index, decision curve analysis (DCA), receiver operating characteristic (ROC) curve and calibration curve (CC) were used for internal validation of the model; the data in the validation group and clinical data of 96 NPC patients (collected from First Affiliated Hospital of Bengbu Medical College) were used for internal and external validation of the model.@*RESULTS@#The clinical data of a total of 2116 NPC patients were included (1484 in model building group and 632 in verification group). Risk factor screening showed that age, race, gender, stage M, stage T, and stage N were all risk factors of death in NPC patients. The risk prediction model for NPC-related death constructed based on these factors had a C-index of 0.76 for internal evaluation, an AUC of 0.74 and a net benefit rate of DCA of 9%-93%. The C-index of the model in internal verification was 0.740 with an AUC of 0.749 and a net benefit rate of DCA of 3%-89%, suggesting a high consistency of the two calibration curves. In external verification, the C-index of this model was 0.943 with a net benefit rate of DCA of 3%-97% and an AUC of 0.851, and the predicted value was consistent with the actual value.@*CONCLUSIONS@#Gender, age, race and TNM stage are risk factors of death of NPC patients, and the risk prediction model based on these factors can accurately predict the risks of death in NPC patients.

OBJECTIVE@#To evaluate the feasibility of S2 alar iliac screw insertion in Chinese children using computerized three-dimension reconstruction and simulated screw placement technique, and to optimize the measurement of screw parameters.@*METHODS@#A total of 83 pelvic CT data of children who underwent pelvic CT scan December 2018 to December 2020 were retrospectively analyzed, excluding fractures, deformities, and tumors. There were 44 boys and 39 girls, with an average age of (10.66±3.52) years, and were divided into 4 groups based on age (group A:5 to 7 years old;group B:8 to 10 years old;group C:11-13 years old;group D:14 to 16 years old). The original CT data obtained were imported into Mimics software, and the bony structure of the pelvis was reconstructed, and the maximum and minimum cranial angles of the screws were simulated in the three-dimensional view with the placement of 6.5 mm diameter S2 alar iliac screws. Subsequently, the coronal angle, sagittal angle, transverse angle, total length of the screw, length of the screw in the sacrum, width of the iliac, and distance of the entry point from the skin were measured in 3-Matic software at the maximum and minimum head tilt angles, respectively. The differences among the screw parameters of S2 alar iliac screws in children of different ages and the differences between gender and side were compared and analyzed.@*RESULTS@#In all 83 children, 6.5 mm diameter S2 iliac screws could be placed. There was no significant difference between the side of each screw placement parameter. The 5 to 7 years old children had a significantly smaller screw coronal angle than other age groups, but in the screw sagittal angle, the difference was more mixed. The 5 to 7 years old children could obtain a larger angle at the maximum head tilt angle of the screw, but at the minimum cranial angle, the larger angle was obtained in the age group of 11 to 13 years old. There were no significant differences among the age groups. The coronal angle and sagittal angle under maximum cephalic angle and minimum cranial angle of 5 to 7 years old male were (40.91±2.91)° and (51.85±3.75)° respectively, which were significantly greater than in female. The coronal angle under minimum cranial angle was significantly greater in girls aged 8-10 years old than in boys. For the remaining screw placement angle parameters, there were no significant differences between gender. The differences in the minimum iliac width, the screw length, and the length of the sacral screws showed an increasing trend with age in all age groups. The distance from the screw entry point to the skin in boys were significantly smaller than that of girls. The minimum width of the iliac in boys at 14 to 16 years of age were significantly wider than that in girls at the same stage. In contrast, in girls aged 5 to 7 years and 11 to 13 years, the screw length was significantly longer than that of boys at the same stage.@*CONCLUSION@#The pelvis of children aged 5 to 16 years can safely accommodate the placement of 6.5 mm diameter S2 alar iliac screws, but the bony structures of the pelvis are developing and growing in children, precise assessment is needed to plan a reasonable screw trajectory and select the appropriate screw length.

Clinical data of 43 patients with hepatitis B-related liver cancer who underwent radical resection treated in 900th Hospital of People′s Liberation Army were prospectively analyzed from January 2020 to December 2021. Among 43 patients, there were 39 males and 4 females, the age was 30-76 years. According to different treatment methods they were divided into two groups, the patients treated by Peg-IFN alfa-2b combined with NAs were devided into the IFN group( n=10), and those treated by NAs alone into the NAs group( n=33). Two-pair semi-quantitative were collected every 3 months after operation. The recurrence-free survival rate, recurrence time after 2 years in the two groups, the clearance rate and the negative rate of HBsAg and HBV DNA in the two groups. Peg-IFN alfa-2b was evaluated in improving the prognosis of hepatitis B-related liver cancer. The measurement data of normal distribution were expressed by mean±standard deviation ( ± s), and t-test was used for comparison between the two groups. Chi-square test was used for comparison between the two groups of count data. Repeated analysis of measurement variance was used for analysis HBsAg and HBV DNA changes of the interferon group overall survival time and recurrence-free surrival time of patients was estimated using Kaplan-Meier method and the difference between groups was assessed using Log-rank test. Results:HBsAg and HBV DNA: The HBsAg clearance rate at 24 weeks and that at 48 weeks in the IFN group were 24.6% and 59.0% respectively. The HBsAg negative rate at 48 weeks was 16.7%. The HBV DNA clearance rate at 24 weeks and that at 48 weeks were 33.9% and 53.8% respectively. The HBV DNA negative rate was 0 at 48 weeks. The levels of HBsAg and HBV DNA in the IFN group decreased gradually with time. There were statistically differences between the levels of HBsAg and HBV DNA at 0 weeks, 24 weeks and 48 weeks( P<0.05). The 2-year overall survival rates of IFN group and NAs group were 100% and 90.9% respectively. The 2-year recurrence-free survival rates were 90.0% and 63.6% respectively. There were no significant statistical differences in the overall survival rate and recurrence-free survival rate between the groups ( P>0.05). The postoperative recurrence time of the IFN group and the NAs group were (15.00±7.07) months and (5.78±3.39) months respectively. The difference between the two groups was statistically significant ( t=3.160, P<0.01). Conclusion:Long-term antiviral therapy of Peg-IFN alfa-2b combined with NAs can prolong the recurrence time of liver cancer, reduce the levels of HBsAg and HBV DNA in serum, and potentially improve the survival rate of the patients compared with therapy of NAs alone.

ABSTRACT
Objective:To observe the role of Huaiqihuang Granules (HQ) in the long-term management of bronchial asthma in young children, and the effective effect on concomitant rhinitis.Methods:A prospective real-world multicenter study was conducted in children aged 2-5 years with asthma diagnosed in the outpatient department (from April 2016 to March 2019)who received either inhaled corticosteroid (ICS)/leukotriene receptor antagonist (LTRA)(control group); inhaled ICS/LTRA plus HQ(combination group), or HQ alone(HQ group). All patients were followed up at week 4, 8, 12 after treatment. The number of days with asthma symptoms, the frequency of severe asthma attacks, the level of asthma control, and the days with rhinitis symptoms in the last 4 weeks were recorded. Differences before and after treatment, and those among groups after treatment were compared using Kruskal- Wallis H test or Wilcoxon rank-sum test. Results:A total of 2 234 eligible patients were recruited, and 2 147 cases completed followed-up visits, including 477, 1 374 and 296 cases in the control group, combination group, and HQ group, respectively. After the treatment, all 3 groups showed significant declines in the days with asthma symptoms, frequency of severe asthma attack and the days with rhinitis symptoms (all P<0.01), and the rate of well-controlled asthma increased significantly ( P<0.01). It lasted until the end of follow-up. Among groups, patients in the combination group showed significantly less days of asthma symptoms than those of the other 2 group at week 8 and 12[0(0, 0.9) d vs.0(0, 0.3) d, P<0.05; 0(0, 0.1) d vs. 0(0, 1.0) d, P<0.01]. Patients in the combination group and HQ group showed a significantly lower rate of severe asthma attacks than that of the control group at week 12 [0(0, 1), 0(0, 1), 0(0, 2), all P<0.05]. The well-controlled rate of asthma in the combination group was significantly higher than that of the control group and HQ group at week 8 and 12 (89.6% vs. 85.9% vs.82.1%, H=15.28; 90.9% vs. 84.1% vs. 81.8%, χ2=29.32, all P<0.01). Conclusions:HQ can significantly alleviate symptoms of asthma and rhinitis, severe attack of asthma, and increase the control rate of asthma when used as an additional treatment or used alone.
ABSTRACT
Objective:To explore the establishment and application of ovarian cancer organoids.Methods:Fresh ovarian tumor tissues, obtaining from patients underwent surgery in the First Affiliated Hospital of Nanjing Medical University between October 2021 and March 2022, were collected, enzymatic degraded, digested, and embedded into matrigel to establish organoids. A total of 32 ovarian cancer samples were collected. Hematoxylin eosin (HE) staining and immunofluorescence (IF) procedure were used to verify the morphological structure of organoids and their expression of molecular markers. 3D cyto-live or dead assay was used to detecte the live or dead cells in organoids. Carboplatin with a concentration ranging from 5 to 80 μmol/L (5, 10, 20, 40, 80 μmol/L) was added to organoids to calculate the 50% inhibitory concentration (IC 50) in different organoids. Results:(1) Organoids from a total of 32 patients were established, of which 18 cases could be passaged stably in the long term in vitro, while 14 could be passaged in the short time. The average amplification time of long-term passage in vitro was over 3 months, and the longest reached 9 months. (2) In HE staining, significant nuclei atypia and local micropapillary structures were observed in organoids. IF staining revealed that ovarian cancer organoids expressed molecular markers similar to primary tumor tissues, such as Pan cytokeratin (Pan-CK), p53, paired box gene 8 (PAX8), and Wilms tumor gene 1 (WT1). (3) In 3D cyto-live or dead assay, a large number of apoptotic cells were observed inside and around the organoids after added carboplatin. The sensitivity to carboplatin varied in 18 organoids could amplify in the long term, with an average IC 50 of (29.5±15.8) μmol/L. Moreover, IC 50 values of 4 organoids derived from patients received neoadjuvant chemotherapy were much higher than the 14 organoids which did not received neoadjuvant chemotherapy [(48.7±11.3) μmol/L vs (24.0±12.1) μmol/L; t=3.429, P=0.022]. Conclusions:Organoids recapitulate ovarian cancers in vitro and could be stably passaged. Organoids derived from patients received neoadjuvant chemotherapy have higher resistance to carboplatin.

Objective:To retrospectively analyze the effects of vitamin D supplementation on the clinical efficacy of ustekinumab (UST) in treatment of patients with Crohn′s disease (CD).Methods:Seventy-one patients with moderate to severe active CD who received the first-line treatment UST from May 2021 to February 2023 were collected by searching the clinical database of the Second Affiliated Hospital of Wenzhou Medical University. The disease activity of CD was evaluated by Harvey-Bradshaw index (HBI) and intestinal inflammation was assessed by simplified endoscopic score for Crohn′s disease (SES-CD). The CD patients were divided into supplementary group ( n=41) and non-supplementary group ( n=30) based on whether vitamin D supplementation (400 U/d) was performed during UST treatment. According to the baseline serum 25 (OH) D level, the patients were divided into vitamin D deficiency group (<20 μg/L, n=42) and non-deficiency group (≥20 μg/L, n=29). The main end points were the differences in the clinical remission (HBI score ≤4) rate and mucosal healing (SES-CD score ≤2) rate between supplementary group and non-supplementary group at week 24 of UST treatment. The secondary end points were the differences in the clinical response (the reduction of HBI score ≥3 compared to week 0) rate and biochemical remission (C-reactive protein (CRP)≤5 mg/L) rate between supplementary group and non-supplementary group at week 8 of UST treatment. A multiple linear regression analysis was performed to investigate the relation between serum 25(OH) D levels and the clinicopathological characteristics of CD patients. Multivariate binary logistic regression models were used to analyze the factors affecting the clinical efficacy of UST at week 8 and 24. Independent sample t test, Mann-Whitney U test, Chi-square test and Fisher′s exact test were used for comparisons between the two groups. Paired t test was used to analyze the differences before and after UST treatment. Results:The results of multiple linear regression analysis for 71 CD patients showed that the baseline serum 25(OH)D level was independent influencing factor for the baseline CRP level ( β=-0.33, 95% confidence interval (95% CI) -0.41 to -0.08, P=0.041) and baseline HBI score ( β= -0.52, 95% CI -0.68 to -0.33, P=0.027). Compared with week 0, the serum 25(OH)D level of supplementary group increased at week 8 ((17.18±5.46) μg/L vs. (13.71±7.73) μg/L), and the difference was statistically significant ( t=-7.81, P<0.001), however, there was no significant difference of serum 25(OH)D in non-supplementary group ((14.85±3.92) μg/L vs. (15.69±5.48) μg/L, P>0.05). At week 8, the HBI score and median CRP level of supplementary group were both lower than those of non-supplementary group (5.71±1.88 vs. 8.34±2.27, 10.83 mg/L (3.95 mg/L, 21.07 mg/L) vs. 16.17 mg/L (6.91 mg/L, 35.48 mg/L)), and the diffierences were statistically significant ( t=0.48, Z=2.87; P<0.001 and =0.001). However, the clinical response rate and biochemical remission rate were both higher than those of non-supplementary group (68.3%, 28/41 vs. 40.00%, 12/30 and 43.9%, 18/41 vs. 13.3%, 4/30), and the differences were statistically significant ( χ2=5.64 and 6.21, P=0.018 and 0.013). Compared with week 0, the serum 25(OH)D level of supplementary group increased ((24.73±8.34) μg/L) at week 24, and the difference was statistically significant ( t=-6.83, P<0.001), however, there was no statistically significant difference in the serum 25(OH)D level of non-supplementary group ((15.59±7.24) μg/L vs. (15.69±5.48) μg/L, P>0.05). At week 24, the decrease of HBI score and SES-CD score of supplementary group were both greater than those of non-supplementary group (difference between week 24 and week 0 -8.96±1.45 vs. -5.33±0.59, -7.00(-10.00, -3.00) vs. -2.00(-2.50, -1.50), and the differences were statisticalcy significant ( t=-5.64 and Z=-3.27, P<0.001 and =0.039). Moreover, the clinical remission rate and mucosal healing rate were both higher than those of non-supplementary group (65.9%, 27/41 vs. 26.7%, 8/30, and 61.0%, 25/41 vs. 30.0%, 9/30), and the differences were statistically significant ( χ2=10.64 and 6.66, P=0.001 and 0.010). At week 24, the analysis of non-supplementary group indicated that the clinical remission rate and mucosal healing rate of patients received vitamin D supplementary therapy were both higher than those of patients without vitamin D supplementary therapy (69.0%, 20/29 vs. 3/13, and 58.6%, 17/29 vs. 2/13), and the differences were statistically significant ( χ2=4.43 and 5.14, P=0.035 and 0.023). Vitamin D supplementing therapy was an independent influencing factor of clinical response rate and biochemical remission rate at week 8, clinical remission rate and mucosal healing rate at week 24 for UST treatment of CD ( OR(95% CI) were 5.83(1.15 to 7.59), 4.91(3.67 to 6.98), 5.13(2.88 to 9.44), 7.01(1.16 to 20.97), respectively; P<0.001, <0.001, <0.001, =0.036). Conclusion:Vitamin D supplementation may help to improve the clinical efficacy of UST treatment in CD patients, especially in patients with vitamin D deficiency.
ABSTRACT
Objective:To explore the relationship between gene polymorphisms of integral protein alpha-4 ( ITGA4) and intercellular adhesion molecule-1 ( ICAM-1) and the risk of ulcerative colitis (UC), and to analyze the effects of ITGA4 and ICAM-1 gene variations on the clinical response of vedolizumab (VDZ) treatment in UC patients at week-14. Methods:From January 1, 2010 to January 31, 2023, at Department of Gastroenterology of the Second Affiliated Hospital of Wenzhou Medical University, a total of 500 UC patients (UC group) and 529 gender- and age-matched healthy controls (healthy control group) were collected. The 500 UC patients were divided into mildly active stage (264 cases) and moderately to severely active stage (236 cases); distal colitis (299 cases), extensive colitis (201 cases); of the 500 UC patients, 120 cases received VDZ treatment, and 78 cases achieved clinical response and the remaining 42 cases had no response at week-14. Chi-square test and unconditional logistic regressionmodel were used to analyze the difference in gene polymorphisms of ITGA4 rs6740847, rs7562325 and ICAM-1 rs5498 gene polymorphisms between UC group and healthy control group, between patients of mildly active stage and patients of moderately to severely active stage, between patients with distal colitis and patients with extensive colitis, between patients with clinical response and patients without response through dominant, recessive, and allelic gene models. Results:The results of dominant gene model analysis showed that, the frequency of the variant allele G and the variant genotype AG+ GG of ITGA4 rs6740847 of UC group were lower than those of healthy control group (28.60% vs. 33.18%, 48.00%vs. 56.15%), the frequency of variant allele T and variant genotype CT+ TT of ITGA4 rs7562325 of UC group were higher than those of healthy control group (37.30% vs.31.57%, 62.20% vs. 54.63%), and the differences were statistically significant( χ2=5.04, 6.83, 7.49 and 6.06, P=0.025, 0.009, 0.006 and 0.014); the frequency of variant allele G and variant genotype AG+ GG of ITGA4 rs6740847 of patients with moderate to severe active UC were lower than those of patients with mild active UC (25.42% vs. 31.44%, 43.22% vs. 52.27%), while the frequency of variant allele T and variant genotype CT+ TT of ITGA4 rs7562325 were both higher than those of mild active UC (40.89% vs. 34.09%, 66.95% vs. 57.96%), and the differences were statistically significant( χ2=4.42, 4.09, 4.93 and 4.29, P=0.036, 0.043, 0.026 and 0.038); the frequency of variant allele G and variant genotype AG+ GG of ITGA4 rs6740847, the variant allele T of ITGA4 rs7562325, and the variant allele G and variant genotype AG+ GG of ICAM-1 rs5498 of patients with extensive colitis UC were lower than those of patients with distal colitis UC (24.38% vs. 31.44%, 39.80% vs. 53.51%, 33.58% vs.39.80%, 19.65% vs.26.09%, 35.82% vs. 45.82%), and the differences were statistically significant( χ2=5.87, 9.05, 3.97, 5.54 and 4.94, P=0.015, 0.003, 0.046, 0.019 and 0.026); the frequency of variant allele G and variant genotype AG+ GG of ITGA4 rs6740847 of patients with clinical response were higher than those of patients without response (34.62% vs.21.43%, 61.54% vs. 33.33%), and the differences were statistically significant( χ2=4.52 and 8.70, P=0.039 and 0.001). The results of recessive gene model analysis showed that, the frequency of variant genotype TT of ITGA4 rs7562325 of UC group was higher than that of healthy control group (12.40% vs.8.51%), and the difference was statistically significant ( χ2=4.18, P=0.041); the frequency of variant allele G and variant genotype GG of ICAM-1 rs5498 of patients with moderate to severe active UC were higher than those of patients with mild active UC (27.33% vs. 20.08%, 8.47% vs. 2.27%), and the differences were statistically significant( χ2=7.30 and 9.72, P=0.007 and 0.002); the frequency of variant allele T and variant genotype TT of ITGA4 rs7562325 of patients with clinical response were lower than those of patients without response (32.05% vs. 45.24%, 10.26% vs. 23.81%), and the differences were statistically significant( χ2=4.09 and 3.93, P=0.043 and 0.047). Conclusions:The variation of ITGA4 rs6740847 gene may reduce the risk and disease activity of UC, and may increase the clinical response to VDZ treatment in UC patients. However, the variation of ITGA4 rs7562325 gene may increase the risk and disease activity of UC, and may reduce the clinical response to VDZ treatment in UC patients. The variation of ICAM-1 rs5498 gene may worsen the disease activity of UC. In addition, the variations of ITGA4 rs6740847, rs7562325 and ICAM-1 rs5498 gene may all reduce the risk of extensive colitis.
ABSTRACT
@#Objective To summarize the effectiveness of Bentall procedure through the right anterior mini-incision. Methods The clinical data of patients who underwent Bentall via right anterior mini-incision from September 2020 to September 2021 in the First Affiliated Hospital of Xi'an Jiaotong University were retrospectively analyzed. Results A total of 14 males with an average age of 55.1±9.3 years and body mass index of 24.7±2.8 kg/m2 were enrolled. The cardiopulmonary bypass (CPB) time was 185.6±32.9 min, the aortic cross-clamping (ACC) time was 144.8±30.3 min, the ventilation time was 18.1±13.5 h, the time in the intensive care unit was 3.7±1.8 d, and the hospital stay time was 13.4±1.6 d. Postoperative complications occurred in 5 patients: 3 patients of pleural effusion, 1 patient of pericardial effusion and 1 patient of postoperative bleeding with secondary thoracotomy hemostasis. The median follow-up time was 4 (2, 6) months. There was no mortality in the hospital or during the follow-up. As for the learning curve, the ACC time, CPB time and operation time were significantly shortened after four cases (P<0.05). Conclusion The right anterior mini-incision for Bentall operation is safe and effective, and has clinical value.
ABSTRACT
Objective@#To understand the current status of obesity and high blood pressure (HBP) comorbidity and their multidimensional influencing factors in children aged 7-12 years in Xiamen, so as to provide reference basis for subsequent preventive measures.@*Methods@#Based on the baseline survey of the Xiamen pubertal development cohort in 2017, a total of 4 798 primary school students from second to sixth grade were selected in the study by cluster random sampling method. And physical examination and questionnaires were conducted. The Logistic regression was used to screen potential variables for obesity combined with HBP. A multivariate Logistic regression model was used to analyse the factors influencing obesity combined with HBP.@*Results@#About 9.15 % children were found with obesity and 11.65% with HBP. The rate of obesity combined with HBP was 3.00% in boys and 1.80 % in girls. The rate of HBP was 8.28% in normal weight children and 26.88% in obese children. Multivariate Logistic regression models showed that consumption of sugary drinks at least once a week ( OR =2.50), daily consumption of salted or pickled vegetables ( OR =4.52), family history of obesity ( OR =3.09) were positively associated with obesity combined with HBP ( P <0.05). Girls ( OR =0.53), consumption of highenergy snacks at least once a week ( OR =0.40) and adequate physical activity ( OR =0.58) were negatively associated with comorbidity of obesity and HBP ( P <0.05).@*Conclusion@#Gender differences in comorbidity burden of obesity and HBP exist among children aged 7-12 years in Xiamen. Dietary behaviour and exercise behaviour are the main dimensions influencing the comorbidity of obesity and HBP. Prevention and control of obesity and HBP in children should be based on multiple dimensions, including diet and exercise behavioural environment, to prevent early the occurrence for comorbidity of obesity and HBP in children.
ABSTRACT
Background: ZNF460 is a member of the zinc finger protein family transcription factors, and is involved in the regulation of a variety of cellular functions. It has been demonstrated to be closely related to digestive system cancers. Aims: To analyze the expression level of ZNF460 in hepatocellular carcinoma (HCC), and explore the effect and potential mechanisms of ZNF460 on tumor cell proliferation. Methods: Immunohistochemical staining was used to determine the expression level of ZNF460 in tissue microarray of 76 HCC and paired adjacent tissues, and the correlation between ZNF460 expression and TNM staging was analyzed. The effect of ZNF460 on HCC cell proliferation was evaluated by CCK‑ 8 and colony formation assays. Genes positively related to ZNF460 expression in HCC were screened through LinkedOmics database, and the KEGG and GSEA pathway enrichment analyses were performed; the possible downstream molecules of ZNF460 were explored and verified by overexpression or knockdown of ZNF460 in HCC cells combined with luciferase reporter assay and other experiments. Results: ZNF460 was highly expressed in HCC and was positively correlated with TNM staging. ZNF460 promoted the proliferation of HCC cells, and the underlying mechanism might be associated with the transcriptional activation of ZDHHC7, the coding gene of palmitoyl transferase DHHC7 and the subsequent STAT3 palmitoylation and phosphorylation. Conclusions: ZNF460 is highly expressed in HCC and promotes cell proliferation and tumor progression via STAT3 activation. It might be a promising molecular marker and therapeutic target for HCC.
