Objective:To investigate the correlation between the expression of GLI1 and im-mune invasion and clinical prognosis in gastric cancer.To study the effect of GLI1 expression on drug resistance in gastric cancer.Methods:The expression difference of GLI1 in gastric cancer and normal tissues was analyzed by using TCGA database,and the effect of clinical features and GLI1 gene ex-pression level on prognosis of patients with gastric cancer was analyzed.The correlation between GLI1 gene expression and tumor immune cell infiltration in gastric cancer tissues was analyzed to explore its influence on drug resistance of chemotherapy drugs and targeted drugs.Clinical samples were collect-ed to analyze the difference of GLI1 expression in gastric cancer and paracancer tissues.Results:The expression of GLI1 in gastric cancer tissues was 1.7 times that in normal tissues,and the overall sur-vival and disease-free survival of patients with high expression are shorter than those with low ex-pression(P＜0.05).The interstitial score,immune score and abundance of immunoinfiltrating cells were higher in the high expression of GLI1 in gastric cancer tissues.High expression of GLI1 reduces drug sensitivity and is positively correlated with the expression of immune checkpoint markers PDCD1(P＜0.05).GLI1 expression was significantly increased in patients with subdifferentiated gastric cancer.Conclusions:GLI1 expression is associated with the prognosis and immune infiltration of patients with gastric cancer,and it may lead to poor prognosis of patients by regulating chemotherapy resis-tance,which may be a potential therapeutic target and molecular marker for gastric cancer.

Objective:To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors.Methods:From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions.Results:Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects ( χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients ( χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications ( χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment ( R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not ( OR=1.83, P<0.001). Conclusions:Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Objective To analyze the effects of vesicoprostatic muscle(VPM)reconstruction on the early urinary control recovery and safety of patients undergoing robot-assisted radical prostatectomy(RARP).Methods A total of 128 patients who underwent RARP in our hospital during Sep.1,2021 and Aug.31,2023 were enrolled and divided into the non-reconstruction group(n=64)and reconstruction group(n=64)using random number table method.The reconstruction group received Montsouris+VPM reconstruction surgery,while the non-reconstructive group underwent Montsouris surgery only.Urinary control and perioperative data were collected with telephone interview,outpatient follow-up and inpatient records.The two groups were matched using overlap weighting and the Kaplan-Meier method was used to calculate urinary incontinence rates at 1,2 and 3 months after extubation.Early urinary control(3 months after extubation),operation time,intraoperative bleeding,positive rate of incision margin,and incidence of early postoperative complications(＜30 days)(Clavien-Dindo scale)were compared between the two groups.Results The recovery rate of urinary control at 1,2 and 3 months after extubation was significantly higher in the reconstruction group than that in the non-reconstruction group(33.9％vs.11.2％;46.7％vs.16.1％;70.6％vs.45.6％,P＜0.05),but the positive rate of resection margin was lower(16.1％vs.41.7％,P＜0.05).There were no significant differences in operation time,intraoperative bleeding and early postoperative complications between the two groups(P＞0.05).Conclusion VPM reconstruction can improve urinary control recovery in RARP patients early after extubation without increasing the risk of surgery.

Objective To construct and verify a nomogram model for predicting social urinary control recovery in patients undergoing robot-assisted radical prostatectomy (RARP) immediately after extubation. Methods A retrospective analysis was conducted on the clinical data of 64 patients diagnosed with prostate cancer and treated by a single surgeon. The immediate urinary control status of the patients after removal of the catheter was evaluated, and LASSO regression was used for feature screening. Multiple Logistic regression was performed on the selected features to determine independent risk factors and establish a predictive model. And the discriminability, calibration, and clinical practicality of the model were evaluated using receiver operating curve (ROC), Hosmer Lemeshow test and calibration curve, and clinical decision curve (DCA) analysis. Results The variables in the outcome prediction model include D'Amico grading and distance of the levator muscle. The area under the ROC curve (AUC) was 0.742 (95%CI, 0.500 to 0.913, P < 0.001), indicating that the model had good discriminability. The calibration curve indicated that the model had good calibration ability. The DCA curve showed good clinical practicality. Conclusion The clinical predictive model developed inthis study can predict the recovery of immediate social urinary control in patients with RARP after surgery, which can further quantify the probability of achieving immediate social continence.

Objective:To investigate the effect of local anesthesia in patients with a PI-RADS score of 5 and ECOG score ≥2 for prostate puncture.Methods:Retrospective analysis of case data of 33 patients admitted to the Subei People's Hospital for prostate puncture from April 2020 to April 2022. Age (82.5±3.6) years. There were 18 cases with hypertensive disease, 8 cases with diabetes mellitus, and 6 cases with both diabetes mellitus and hypertensive disease. Body mass index (25.2±3.5) kg/m 2. prostate-specific antigen (PSA)(131.5±69.7) ng/ml. prostate volume (38.5±21.4) ml. all patients had a PI-RADS score of 5 on multiparametric magnetic resonance (mpMRI) and an Eastern Cooperative Oncology Group (ECOG) score ≥2. All 33 cases in this group underwent trans-perineal targeted prostate puncture using local anesthesia at the tip of the prostate. The visual analog score (VAS) and visual numeric score (VNS) were applied by the same surgeon to assess the patient's pain level and satisfaction at the time of puncture (VAS-1 and VNS-1) and 30 min after puncture (VAS-2 and VNS-2), and to record the duration of the procedure and the occurrence of postoperative complications. Results:In this group of 33 cases, the VAS-1 score was (1.9±0.3) and the VAS-2 score was (0.1±0.2); the VNS-1 score was (2.9±0.2) and the VNS-2 score was (3.9±0.1). Postoperative pathological results indicated that one of the 33 patients had a negative puncture result (pathology report indicating interstitial inflammation), while the rest of the patients had a positive puncture pathology report (puncture pathology report indicating prostate cancer), with a positive rate of 97%. One case of postoperative carnal haematuria occurred, which gradually improved after the patient was advised to drink water and take alpha-blockers. No perineal hematoma occurred, and all patients did not suffer complications such as urinary tract infection, urinary retention, azoospermia, vagal reaction, and infectious shock.Conclusion:In patients with a PI-RADS score of 5 and ECOG score ≥2, the use of single-hole local anesthesia for performing trans-perineal targeted puncture biopsy has the advantages of good paroxysmal pain and high safety.

Objective:To explore the quality differences of systemic biopsy specimens from different regions in prostate biopsy.Methods:The data of 806 patients who underwent transperineal prostate biopsy from May 2013 to December 2020 in Northern Jiangsu People’s Hospital were retrospectively reviewed. The median age of the patients was 72 (66, 77) years old, median PSA was 18.4 (10.3, 34.2) ng/ml, and prostate volume was 43 (32, 56) ml. Tissue quality were graded from low to high as follows. One score means multiple fragments with fragmented tissue ≤5 mm. Two scores means at least one fragment >5 mm and ≤10 mm. Three scores means at least one fragment >10 mm. The prostate specimens fragmentation scores and the length of the specimens in different regions of the prostate were collected to analyze.Results:A total of 806 patients were included in our study. The number of tissues was 8 866, and the mean length of tissues was 1.2 (1.0, 1.5) cm. The tissues of different region were scored according to the scoring criteria, of which 618 (7.0%) prostate tissues were scored as 1 score, 2 720 (30.7%) tissues were scored as 2 scores, and 5 528 (62.4%) tissues were scored as 3 scores. In the prostate apex, tissue quality of 1 score accounted for 11.7%(94/806), 2 scores accounted for 34.7%(280/806), and 3 scores accounted for 53.6%(432/806). While in the prostate base, tissue quality of 1 score accounted for 6.5%(524/8 060), 2 scores accounted for 30.3%(2 449/8 060), and 3 scores accounted for 63.2%(5 096/8 060)( H=35.850, P<0.05). The mean length of the prostate apical tissue was 1.0 (0.8, 1.3) cm, which was significantly shorter than prostate basal tissue of 1.2(1.0, 1.5) cm ( Z=-11.353, P<0.05). Conclusions:In transperineal prostate biopsy, the apical tissue was more fragmented and shorter, prostate apex should be concerned.

Objective:To investigate the factors affecting the effect of periprostatic nerve block (PNB), establish a prediction model of pain degree, and verify the prediction efficiency.Methods:The clinical data of 314 patients who underwent transperineal prostate biopsy in our hospital from June 2022 to January 2023 were retrospectively analyzed. The median age was 71 (65, 76) years, the median prostate-specific antigen (PSA) was 14.6 (10.70, 24.65) ng/ml, and the median puncture needle number was 21 (19, 23) needles, median prostate volume 45.86 (31.52, 67.96) ml, median body mass index (BMI)24.02(22.97, 25.33)kg/m 2, including 109 patients with a history of diabetes, 90 patients with a history of surgery, and 57 patients with a history of severe trauma. The patients were divided into mild pain group (1-3 points), moderate pain group (4-6 points) and severe pain group (7-10 points) according to the intraoperative visual analogue scale (VAS). According to the clinical characteristics, the factors affecting the effect of PNB were analyzed by univariate analysis and multiple ordered logistic regression method. R language was used to construct a nomogram model for predicting PNB effect, receiver operating characteristic (ROC) curve and calibration curve were drawn, and Hosmer-Lemeshow test was carried out to verify the prediction efficiency of the model. Results:The results of univariate analysis showed that 171 patients in the mild pain group had a median age of 71 (65, 75) years, a median PSA14.5 (9.6, 24.6) ng/ml, a median number of puncture needles of 20 (18, 22), and a median prostate volume of 34.94 (26.36, 45.12) ml, median BMI24.17(23.14, 25.79)kg/m 2, including 74 patients with a history of diabetes, 51 patients with a history of surgery, and 40 patients with a history of severe trauma; There were 110 patients in the moderate pain group, the median age was 71 (65, 76) years, the median PSA14.8 (11.03, 24.27) ng/ml, the median number of puncture needles was 23 (20, 24) needles, median prostatic volume 63.24 (49.14, 78.72) ml, median BMI23.91(22.58, 24.88)kg/m 2, including 26 patients with a history of diabetes, 29 patients with a history of surgery, and 10 patients with a history of severe trauma; In the severe pain group, 33 patients had a median age of 73 (67, 78) years, a median PSA14.6 (10.85, 34.80) ng/ml, and a median puncture needle number of 23 (22.5, 24) needles, median prostate volume 70.64 (61.50, 104.51) ml, median BMI24.32(23.00, 26.06)kg/m 2, including 9 patients with a history of diabetes, 10 patients with a history of surgery, and 7 patients with a history of severe trauma. The results of univariate analysis showed that the number of puncture needles ( P<0.01), prostate volume ( P<0.01), history of diabetes ( P=0.002) and history of major trauma ( P= 0.009) were the factors affecting the effect of PNB. Multiple logistic regression analysis showed that puncture needle number ( P=0.009), prostate volume ( P<0.01) and diabetes history ( P=0.041) were independent risk factors for PNB effect. The area under ROC curve (AUC) of the moderate and above pain prediction model was 0.872, P<0.01; the area under ROC curve of the severe pain prediction model was 0.817, P<0.01; the result of Hosmer-Lemeshow test of the moderate and above pain prediction model was χ2=5.001, P=0.757. The results of the severe pain prediction model were χ2=4.452 and P=0.814. The calibration curve was established, which showed that the prediction probability of pain degree was in good agreement with the actual risk. Conclusions:The number of puncture needles, prostate volume and history of diabetes are the risk factors affecting the effect of PNB. The prediction model of PNB effect based on this model can be used to predict the pain degree of patients undergoing prostate biopsy after PNB.

Objective: To explore current vitamin D status and influential factors of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China. Methods: According to the "province-city-hospital" sampling technical route, a total of 1 531 healthy children under 7 years of age were sampled from 11 provinces, autonomous regions or municipalities in China by the cluster random sampling method from November 2020 to November 2021. The demographic information, family conditions, behavior and living habits and feeding behaviors were collected using unified questionnaire. Serum 25-hydroxyvitamin D(25(OH)D) levels were measured by liquid chromatography-tandem mass spectrometry. Serum 25(OH)D<30 nmol/L was considered deficient and 30-50 nmol/L was considered insufficient. With 25(OH)D≤50 nmol/L as the dependent variable, multivariate Logistic regression was applied to analyze the association between vitamin D deficiency and insufficiency and potential influential factors. Results: The prevalence of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China was 14.0% (215/1 531), 3.8% (25/664) and 21.9% (190/867) in 0-<3 and 3-<7 of age years, respectively. Compared to children aged 0-<3 years, children aged 3-<7 years had a 2.6-fold increased risk of vitamin D deficiency and insufficiency (OR=3.60, 95%CI 1.93-6.72, P<0.001). Frequent sunlight exposure (OR=0.46, 95%CI 0.29-0.73, P=0.001), vitamin D supplementation (sometimes, OR=0.33, 95%CI 0.21-0.51, P<0.001; daily, OR=0.20, 95%CI 0.11-0.36, P<0.001) and infant formula intake(4-7 times per weeks, OR=0.43, 95%CI 0.28-0.68, P<0.001) were protective factors for vitamin D deficiency and insufficiency. Conclusion: Vitamin D deficiency and insufficiency are common among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China, which is affected by age, sunlight exposure, vitamin D supplementation and infant formula intake.

OBJECTIVE: To investigate the bacteriostatic effect of platelet-rich plasma (PRP) and its derivative platelet gel (PG) supernatant on Escherichia coli in vitro and its relationship with platelet factor 4 (PF4). METHODS: Apheresis platelets donated by healthy volunteers were obtained from the Blood station of Lu an Blood Center as the source of PRP. The counts of platelet, white blood cell and red blood cell in PRP and its derivative PG supernatant were detected by automatic hematology analyzer. Bacterial growth of PRP and PG supernatants co-cultured with bacteria for different time was observed by plate coating culture method, and the contents of PF4 in PRP and PG supernatants were detected by ELISA. RESULTS: Apheresis platelets were collected from 28 healthy volunteers with a median age of 33 (21-56) years old. PRP can inhibit the growth of escherichia coli, but there were individual differences in antibacterial effect within 24 hours. PRP of 13 healthy volunteers had strong antibacterial effect at 24 hours, 7 cases had weak antibacterial effect at 24 hours, and 8 cases had no antibacterial effect at 24 hours. PG supernatant showed no significant individual difference, and all of them had bacteriostatic effect within 12 hours, but no bacteriostatic effect after 12 hours. There was no statistical difference in the bacteriostatic effect of PRP at 24 hours between healthy volunteers aged ≤30 years and >30 years (P>0.05), and there was no statistical difference between the white blood cell count ≤0.1×10⁹/L and (0.1-1) ×10⁹/L groups (P>0.05). There was significant difference in the bacteriostatic effect of PRP between the two groups with platelet content ≤1 000×10⁹/L and >1 000×10⁹/L (P<0.05). The platelet count in PRP was higher than that in PG supernatant ［(911.57±160.52) ×10⁹/L vs 0］. The PF4 level in PRP was higher than that in PG supernatant (23623.34±9822.14 vs 6664.74±4065.83, P<0.05). CONCLUSION Both PRP and PG supernatant have antibacterial effects in Escherichia coli. The bacteriostatic effect of PRP was better than that of PG supernatant, and the platelet and PF4 contents in PRP were higher than those in PG supernatant, suggesting that the platelet and PF4 levels play an important role in bacteriostasis.

Objective: A multicenter Chinese mainland survey was conducted to investigate the sensitization distribution characteristics of cat, dog and horse dander in patients with allergic diseases, so as to provide clinicians with epidemiological data of common animal allergens and useful information for the prevention and treatment of allergies in cats, dogs and horses. Methods: The epidemiological investigation and design was adopted. This study is based on the national epidemiological survey of allergic diseases led by the first affiliated Hospital of Guangzhou Medical University. From January to December in 2021, a total of 2 122 patients diagnosed with allergic diseases were included in the outpatient department of respiratory department/pediatrics/allergy department of 14 units such as the First Affiliated Hospital of Guangzhou Medical University, and 222 healthy subjects were included as controls from the physical examination center of the above units in the same period. All the subjects filled out the allergic disease questionnaire under the guidance of doctors, and the allergen-specific immunoglobulin E (sIgE) of cats, dogs and horses of all subjects were detected by magnetic particle chemiluminescence system. The epidemiological characteristics of three animal allergens in different diseases, ages and regions were analyzed. Chi square test was used to analyze the frequency difference between groups, t test or Mann Whitney U test was used to test the distribution difference between two groups, and one-way ANOVA or Kruskal Wallis H test was used to compare the distribution difference between multiple groups. Bar chart, Venn-plot and radar chart were drawn to show the sensitization distribution characteristics. A small number of missing values caused by subjects' omission have been excluded during the analysis. Results: The 2 122 patients with allergic diseases were 57.35% male (1 217/2 122) and 40.95% female (869/2 122), and 1.70% (36/2 122) patients had loss of gender information. The age of patients with allergic diseases was 9.0 (6.0, 28.0) years, while that of healthy controls was 29.0 (13.0, 39.0) years old, and there were 1.7% (36/2 122) and 0.9% (2/222) subjects with missing age information, respectively. The proportion of caesarean section in allergic patients was significantly higher than that in healthy controls (31.4% vs. 17.6%,χ²=16.582,P<0.001) [2.5% (54/2 122) of the patient group and 5.4% (12/222) of the control group had missing birth mode information], and the proportion of patients with allergic diseases who reported that both parents had allergic diseases was significantly higher than that of the control group (35.7% vs. 9.5%, χ²=65.171,P<0.001). Patients with allergic diseases are mainly school-age (6-12 years old) and adolescents (12-18 years old). 16.4% of patients with allergic diseases were sensitized to cat dander, 10% and 6% to dog and horse dander. The sensitization rate of cat dander in patients with rhinitis, asthma, conjunctivitis, food allergy and atopic dermatitis was the highest (16.4%-21.6%), followed by dog dander (10.2%-15.2%). The prevalence of allergic rhinitis was the highest among different animal sensitized populations. The proportion of cat, dog and horse allergens sensitized at the same time is between 10%-15%, and the proportion of any two or more animal dander sensitized at the same time is about 45%. Animal allergens are associated with respiratory allergic diseases, especially allergic rhinitis with allergic conjunctivitis. There were significant differences in the distribution of positive rates of three animal allergens in different regions, and the highest positive rate of cat dander was found in all provinces of the country. Conclusion: The sensitization rate of animal dander allergens increased significantly, and the highest was in children and adolescents. Cat dander is the most common animal allergen, followed by dog. Different animals show obvious cross or common sensitization due to their high homology.
