Objective To investigate the influencing factors associated with the comorbidity of inflammatory bowel disease (IBD) and depression. Methods A case-control study was conducted based on the ^“Healthcare Big Data Platform^” of a tertiary class-A comprehensive hospital in Shandong Province. IBD comorbid with depression was served as the case group and IBD without depression was served as the control group. Propensity score matching (PSM) was performed by matching the case group with the control group in a ratio of 1:2 according to the age and gender of the patients. Conditional logistic regression model was used to explore the influencing factors associated with the comorbidity of IBD and depression. Results A total of 405 patients with IBD were enrolled in this study, including 270 patients without depression and 135 patients comorbid with depression. The results of conditional logistic regression showed that the use of immunosuppressants (OR=2.84, 95% CI: 1.00-8.07) and glucocorticoids (OR=2.05, 95% CI: 1.17-3.58), dementia (OR=5.20, 95% CI:1.59-17.05), cardiovascular disease (OR=3.58, 95% CI: 1.84-6.98) and cancer (OR=2.63, 95% CI: 1.16-5.95) were associated with the comorbidity of depression and IBD. Conclusion Attention should be paid to the use of immunosuppressants and glucocorticoids in the population of IBD comorbid with depression, and the coexistence of physical diseases such as dementia, cardiovascular disease and cancer. Early prevention and targeted treatment measures should be taken for high-risk populations to reduce their risk of depression and improve their quality of life and health.

To investigate the therapeutic effect and related mechanisms of hordenine on ovalbumin (OVA)-induced allergic rhinitis (AR) in rats, HE and AB-PAS staining were used to detect the improvement of pathological damage to the nasal mucosa induced by hordenine. ELISA was employed to detect the effect of hordenine on OVA-sIgE in serum and IL-4 in the nasal mucosa supernatant of rats. IHC and Western blot experiments were undertaken to examine the effect of hordenine on Th1/Th2 cell balance. Bioinformatics analysis was performed to predict pathways, which were verified by in vivo and in vitro experiments. The experimental results showed that hordenine could alleviate the behavioral manifestations of OVA-induced AR rats, alleviate nasal mucosal pathological damage caused by AR, and reduce the secretion of OVA-sIgE and IL-4. In addition, hordenine could regulate the Th1/Th2 balance. Bioinformatics analysis results showed that the potential pathway of action of hordenine on AR was the phosphoinositide 3 kinase (PI3K)/protein kinase B (Akt) signaling pathway. The in vivo experimental results showed that the expression of PI3K and p-Akt proteins in the nasal mucosa of the model group rats was significantly increased (P < 0.01), and that the protein expression level was significantly decreased after the administration of hordenine, which was also confirmed by an in vitro experiment. This study suggests that hordenine may regulate Th1/Th2 cell balance through the PI3K/Akt signaling pathway, thereby exerting an alleviating effect on OVA-induced AR.

Objective:To evaluate the effect of propofol on parvalbumin (PV) neurons in the medical prefrontal cortex(mPFC)of rats with social behavior disorders induced by chronic sleep deprivation.Methods:Forty-two SPF male Sprague-Dawley rats, aged 8 weeks, weighing 200-250 g, were divided into 3 groups ( n=14 each) using a random number table method: control group (group Con), chronic sleep deprivation plus natural sleep group (group CSD+ NS), and chronic sleep deprivation plus propofol group (group CSD+ Pro). Sleep deprivation model was established by the modified multiple platform method, the rats were placed in the sleep-deprivation tank for 20 h a day (14: 00-10: 00), and allowed to sleep naturally for 4 h (10: 00-14: 00) a day for 28 consecutive days. Propofol 40 mg/kg was intraperitoneally injected for 28 consecutive days after sleep deprivation in CSD+ Pro group. While the equal volume of 10% fat emulsion was given in Con and CSD+ NS groups. After the end of sleep deprivation, a three-box social experiment was used to detect the social behavior of rats, and the number of the PV positive cells and density of the perineuronal network (PNN) in the mPFC area were measured by immunofluorescence. Results:Compared with group Con, the pertentage of rapid eye movement sleep and sniffing time preference coefficients for the strange rat 1 in the first stage and for the strange rat 2 in the second stage were significantly decreased, and the number of the PV positive cells and density of PNN in the mPFC area were decreased in group CSD+ NS ( P<0.05). Compared with group CSD+ NS, the sniffing time preference coefficients for the strange rat 1 in the first stage and for the strange rat 2 in the second stage were significantly increased, the number of the PV positive cells and density of PNN in the mPFC area were increased( P<0.05), and no significant change was found in the percentage of the rapid eye movement sleep in group CSD+ Pro. Conclusions:Propofol probably increases the number and function of PV neurons in the mPFC and ameliorates sleep deprivation-induced social behavior disorders in sleep-deprived rats.

Objective To investigate the effect of esketamine combined with sufentanil for postoperative patient-controlled intravenous analgesia(PCIA)on rebound pain after single nerve block.Methods From January 2021 to December 2022,80 patients undergoing upper limb fracture surgery in Jinshan Hospital,Fudan University with single nerve block anesthesia were included and randomly divided into two groups:the Ket group(esketamine combined with sufentanil PCIA)and the Ctrl group(sufentanil PCIA),with 40 patients in each group.Several indicators were recorded,including pain scores at 8 h,12 h,24 h,and 48 h postoperatively,the time to first pain and its score,pain scores 30 min after pressing the PCIA pump self-control button,as well as opioid consumption at 24 h and 48 h postoperatively,and the number of PCIA button presses.Rebound pain was defined as a sudden transition from"no pain"to"severe pain"(NRS ≥ 7)requiring pressing the PCIA self-control button.Results Rebound pain occurred in 17(45.95％)patients in the Ctrl group and 12(36.36％)patients in the Ket group,with no statistically significant difference.The Ket group had significantly lower sufentanil consumption and fewer PCIA presses at 24 h postoperatively compared to the Ctrl group(P=0.007).At 48 h postoperatively,there was no significant difference in sufentanil consumption and PCIA presses among patients who experienced rebound pain in the two groups.At 30 min after pressing the PCIA button for breakthrough pain,12 patients(100.00％)in the Ket group had NRS＜4,compared to 3 patients(17.65％)in the Ctrl group,with a statistically significant difference(P=0.02).Conclusions Compared with using sufentanil alone for PCIA,the combination of esketamine and sufentanil does not reduce the incidence of rebound pain following single nerve block in upper limb fracture surgery.However,the combination of esketamine and sufentanil may provide a faster relief of rebound pain.

Objective To investigate the epidemiological characteristics and spatial distribution characteristics of Clonorchis sinensis human infections in Guangdong Province from 2016 to 2022, so as to provide insights into formulation of the clonorchiasis control measures in the province. Methods Xinhui District of Jiangmen City, Longmen County of Huizhou City and Wengyuan County of Shaoguan City in Guangdong Province were selected as fixed surveillance sites for human clonorchiasis from 2016 to 2022, and additional 10% to 15% counties (districts) endemic for clonorchiasis were sampled from Guangdong Province as mobile surveillance sites each year from 2016 to 2022. A village (community) was randomly selected from each surveillance site according to the geographical orientations of east, west, south, north and middle, and subjects were randomly sampled from each village (community). C. sinensis eggs were detected in subjects’ stool samples using the Kato-Katz technique, and the prevalence and intensity of C. sinensis infections were calculated. In addition, subjects’ gender, age, ethnicity, educational level and occupation were collected. The Guangdong Provincial 1:1 million electronic map in vector format was downloaded from the National Geomatics Center of China, and kernel density analysis and spatial autocorrelation analysis of C. sinensis human infections in Guangdong Province from 2016 to 2022 were performed using the software ArcGIS 10.7. Results A total of 153 188 residents were tested for C. sinensis infections in Guangdong Province from 2016 to 2022, including 75 596 men (49.35%) and 77 592 women (50.65%), and there were 5 369 residents infected with C. sinensis, with 3.50% overall prevalence of infections. The prevalence rates of severe, moderate and mild C. sinensis infections were 0.76%, 7.26% and 91.97% among C. sinensis-infected residents in Guangdong Province from 2016 to 2022, and there were age-, gender-, ethnicity-, occupation- and educational level-specific prevalence of C. sinensis human infections (χ² = 2 578.31, 637.33, 52.22, 2 893.28 and 1 139.33, all P values < 0.05). Global spatial autocorrelation analysis showed a cluster in the prevalence of C. sinensis human infections in Guangdong Province (Moran’s I = 0.63, Z = 27.31, P < 0.05). Kernel density analysis showed that the prevalence of C. sinensis human infections with a high kernel density in Guangdong Province was mainly distributed along the Zhujiang River basin in Pearl River Delta areas, followed by in eastern and northern Guangdong Province. In addition, local spatial autocorrelation analysis identified 73 high-high clusters of the prevalence of C. sinensis human infections in Guangdong Province. Conclusions The prevalence of C. sinensis human infections was high in Guangdong Province from 2016 to 2022, and mild infection was predominant among all clonorchiasis cases, with spatial clusters identified in the prevalence of C. sinensis human infections. Targeted clonorchiasis control measures are required among high-risk populations and areas.

Objective:To explore the central venous catheter maintenance compliance among nurses in Class Ⅱ and Ⅲ hospitals in Hunan Province.Methods:From January to March 2022, 297 nurses from 22 Class Ⅱ and Ⅲ hospitals in Hunan Province were selected as the research subject by convenience sampling. Nurses were surveyed using the self-made Central Venous Catheter Maintenance Compliance Questionnaire. Multiple linear regression was used to analyze the influencing factors of nurse compliance with central venous catheter maintenance, the items of the Central Venous Catheter Maintenance Compliance Questionnaire were analyzed.Results:A total of 297 questionnaires were distributed, and 268 valid questionnaires were collected, with an effective response rate of 90.24%. The hospital level, specialized training in intravenous therapy, and age were the influencing factors on the compliance of nurses with central venous catheter maintenance. Analyzing specific items, only 34.3% (92/268) of nurses correctly executed the item "alcohol cotton pads were recommended", and only 66.4% (178/268) of nurses correctly performed the item "sterile gauze dressings should be replaced at least every two days".Conclusions:There is a certain gap in the central venous catheter maintenance compliance among nurses at all levels of hospitals, and there is a need to improve compliance in disinfection of infusion joints and replacement of sterile gauze dressings. We should strengthen the training of specialist nurses, especially the training of nurses in ClassⅡ hospitals on specialized skills related to intravenous therapy.

Objective To observe the differences in the expression levels of the hypoxia-inducible factor-1α/heme oxygenase-1/vascular endothelial growth factor A (HIF-1α/HO-1/VEGF-A) signaling pathway under different maturation outcomes of arteriovenous fistula (AVF) in patients with stage 5 chronic kidney disease, and explore the regulatory mechanism of the HIF-1α/HO-1/VEGF-A signaling pathway in the maturation process of AVF. Methods A total of 45 patients with AVF surgery for stage 5 chronic kidney disease were selected as research objects, vascular specimens were collected during the AVF surgery, and the patients were divided into AVF maturation group (n=35) and AVF poor maturation group (n=10) based on the AVF maturation outcomes within 8 weeks after surgery. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the gene expression levels of HIF-1α, HO-1 and VEGF-A in the HIF-1α/HO-1/VEGF-A signaling pathway; the Western blotting was used to detect the protein expression levels of HIF-1α, HO-1 and VEGF-A; the enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of downstream inflammatory factors such as interleukin-1β (IL-1β), interleukin-8 (IL-8), and transforming growth factor-β (TGF-β). Results The expression levels of HIF-1α mRNA, HO-1 mRNA, and VEGF-A mRNA in the AVF maturation group were significantly higher than those in the AVF poor maturation group (P < 0.01); the protein expression levels of HIF-1α, HO-1 and VEGF-A in the AVF maturation group were significantly higher than those in the AVF poor maturation group (P < 0.01); the expression levels of IL-1β, IL-8 and TGF-β in the AVF maturation group were significantly lower than those in the AVF poor maturation group (P < 0.01). Conclusion The upregulation of the HIF-1α/HO-1/VEGF-A signaling pathway is conducive to the early maturation of AVF. The measurement of the expression levels of the HIF-1α/HO-1/VEGF-A signaling pathway has a certain predictive significance for the early maturation outcome of AVF.

Objective:To explore the influencing factors and effectiveness of community follow-up in patients with cardiac implantable electronic device (CIED) implantation.Method:A total of 132 patients who received CIED implantation in the Department of Cardiology of Tongren Hospital, Shanghai Jiao Tong University School of Medicine from February 2021 to February 2022 were enrolled in this prospective cohort study. Among them 33 patients were followed up in community health service centers associated with Tongren Hospital (community follow-up group) and 99 matched patients were followed up in the CIED outpatient clinic of the hospital (outpatient follow-up group) with a ratio of 1∶3. The clinical data of the selected patients were collected through a questionnaire survey; the follow-up data were extracted through the CarelinkExpress electronic follow-up platform and the CIED outpatient information system of Tongren Hospital. Adjustment of the treatment protocol or CIED parameters at follow-up, and the referral from the community health service centers were defined as visit with-an-action (VWA). The endpoint of follow-up was the occurrence of major adverse events. The multivariate logistic regression model was used to analyze the factors influencing patient selection for community follow-up.Results:The univariate analysis showed that the frequency of visits to community health service centers and the service contracting rate in community follow-up group were higher than those of outpatient follow-up group ( P<0.05). The multivariate logistic regression analysis showed that the contracted community physician service was an independent influencing factor of patient choosing community follow-up ( OR=2.143, 95% CI: 1.103-4.166, P=0.025). A total of 469 visits of followed up occurred in 132 patients, including 45 community visits and 424 outpatient visits. VWA accounted for 22.2% (10/45) in the community follow-up group, and 17.2% (73/424) in the outpatient follow-up group ( P>0.05). There was no significant difference in the safety and effectiveness indicators (VWA, major adverse events, and unplanned follow-up) between the two groups ( P>0.05). More patients in the community follow-up group walked to the hospital than the outpatient follow-up group ( P<0.05);and the main transportation for the later was by bus or taxi(42(42.4%)or 41(41.4%)). The average waiting time in the community follow-up group was significantly shorter than that in outpatient follow-up group ( P<0.05). The total time required for a single follow-up in the community follow-up group was 50.0 (45.0, 59.5) minutes, which was significantly shorter than that in the routine outpatient follow-up group (107.0 (90.0, 135.0) minutes, P<0.05). Conclusions:The contracting with community physicians is an independent influencing factor for CIED implanted patients to choose community follow-up. The safety and effectiveness of community follow-up are comparable to routine outpatient follow-up, and community follow-up is more convenient.

Objective:To investigate the effects of hydroxysafflor yellow A (HSYA) on depressive-like behavior and expression of type A γ-aminobutyric acid receptor(GABAAR)in hippocampus of chronic restraint stress model mice.Methods:The SPF grade male C57BL/6C mice were divided into Control group, HSYA group, Model group, Model + HSYA group and Model + fluoxetine group according to random number table method, with 12 mice in each group.Mice model of depression was established by chronic restraint stress.Mice in HSYA group and Model+ HSYA group were intraperitoneally injected with HSYA(20 mg/kg), mice in Model+ fluoxetine group were injected intraperitoneally with fluoxetine (10 mg/kg), and mice in Control group and Model group administered with 0.9% sodium chloride solution intraperitoneally once a day for 14 days.Then, the forced swimming test (FST) and tail suspension test (TST) were performed to evaluate the depressive-like behavior of mice, and the protein expression levels of different subtypes of GABAAR in the hippocampus of mice were determined by Western blot.SPSS 19.0 and GraphPad Prism 8.0 software were used for data statistical analysis and mapping.One-way ANOVA was used for comparison among groups, and Tukey-HSD test was used for further pairwise comparison.Results:(1) In the behavioral tests, there were significant differences in swimming immobility time of FST and tail suspension immobility time of TST among the five groups ( F=21.59, 20.81, both P<0.05). The swimming immobility time ((143.91±9.97) s) and tail suspension immobility time (( 107.00±6.54) s) in Model group were higher than those in Control group ((52.92±6.70) s, ( 43.50±5.96) s, both P<0.05). There were no significant difference in swimming immobility time and tail suspension immobility time between Model+ HSYA group ((26.17±7.69)s, ( 20.17±7.89)s) and Model+ fluoxetine group ((61.60±16.22)s, (34.14±10.74)s)(both P>0.05), but the swimming immobility time and tail suspension immobility time in these two groups were lower than those in Model group (both P<0.05). (2) The Western blot results showed that there were significant differences in the expression of GABAARβ1 and GABAARβ2 protein in hippocampus among the four groups ( F=12.21, 11.40, both P<0.05). The expression levels of GABAARβ1(45.60±10.76) and GABAARβ2 (46.27±4.82) protein in hippocampus of Model group were lower than those in Control group ((100.00±3.44), (100.00±3.26), both P<0.05). Compared to Model group, the expression of GABAARβ1 (79.91±5.00) and GABAARβ2 (79.08±5.53) protein in hippocampus of Model+ HSYA group were higher (both P<0.05). In addition, the expression of GABAARα1 and GABAARγ1 proteins in hippocampus were not significantly different among the four groups( F=0.23, 0.10, both P>0.05). Conclusion:HSYA can effectively alleviate depressive-like behavior in depression model mice, which may be related with the upregulation of GABAARβ1 and GABAARβ2 of hippocampus tissue.

Objective:To investigate the clinical outcome after surgery and first 131I treatment in patients with moderate-risk papillary thyroid cancer (PTC), and analyze the relevant factors that affect the therapeutic effect. Methods:From January 2018 to April 2019, 135 patients (48 males, 87 females; age (42.7±11.1) years) with moderate-risk PTC in the Second Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. According to the 2015 American Thyroid Association (ATA) guidelines, patients were divided into excellent response (ER) group, inderteriminate response (IDR) group, biochemical incomplete response (BIR) group and structural incomplete response (SIR) group, of which IDR, BIR, SIR were collectively referred to as the non-ER group. χ2 test and Mann-Whitney U test were used to compare the general clinical features between the ER and non-ER groups, and then multivariate logistic regression analysis was performed. The predicted value of pre-ablation stimulated thyroglobulin (ps-Tg) to ER was assessed by ROC curve analysis. Results:The treatment responses of 94 patients were ER, and those of 41 were non-ER. The differences in tumor size (0.80(0.50, 1.10) vs 1.00(0.55, 1.50) cm; U=1 491.50, P=0.036), the number of metastatic lymph nodes (3(2, 5) vs 4(2, 12); U=1 422.00, P=0.015), metastatic lymph node size (0.50(0.30, 0.65) vs 0.50(0.30, 1.45) cm; U=1 396.50, P=0.013), metastatic lymph node involvement rate (50%(30%, 70%) vs 60%(50%, 85%); U=1 441.50, P=0.024), metastatic lymph node location (central/lateral: 76/18 vs 24/17; χ2=7.40, P=0.007) and ps-Tg level (2.1(0.8, 5.3) vs 14.0(3.2, 35.2) μg/L; U=680.00, P<0.001) were statistically significant between the ER and non-ER groups. Multivariate logistic regression analysis showed that ps-Tg (odds ratio ( OR)=1.200, 95% CI: 1.107-1.302, P<0.001) was an independent factor influencing ER. The cut-off value of ps-Tg for predicting ER was 7.38 μg/L, with the sensitivity and specificity of 68.3%(28/41) and 87.2%(82/94) respectively. Conclusion:Moderate-risk PTC patients with smaller tumor size, fewer metastatic lymph nodes, lower metastatic lymph node involvement rate, metastatic lymph nodes in central area, smaller metastatic lymph node size, and ps-Tg<7.38 μg/L have better therapeutic effect after initial 131I treatment.
