Objective To investigate the trends in the global burden due to cystic echinococcosis from 1990 to 2021, and to predict the global burden of cystic echinococcosis from 2022 to 2035, so as to provide insights into formulation of the cystic echinococcosis control strategy. Methods The global age-standardized prevalence, mortality, disability-adjusted life years (DALYs) rates and their 95% uncertainty intervals (UI) of cystic echinococcosis from 1990 to 2021 were captured from the Global Burden of Disease Study 2021 (GBD 2021) database, and the trends in the global burden of cystic echinococcosis from 1990 to 2021 were analyzed using the Joinpoint regression model. The associations between the global burden of cystic echinococcosis and socio-demographic index (SDI) were examined using a smoothing spline model and frontier analysis, and the global burden of cystic echinococcosis was projected from 2022 to 2035 using the Bayesian age-period-cohort (BAPC) model. Results The global agestandardized prevalence, mortality and DALYs rates of cystic echinococcosis were 7.69/10⁵ [95% UI: (6.27/10⁵, 9.51/10⁵)], 0.02/10⁵ [95% UI: (0.01/10⁵, 0.02/10⁵)], and 1.32/10⁵ [95% UI: (0.99/10⁵, 1.69/10⁵)] in 2021. The global age-standardized prevalence of cystic echinococcosis appeared a tendency towards a rise by 0.14% per year from 1990 to 2021, and the global age-standardized mortality and DALYs rates of cystic echinococcosis appeared a tendency towards a decline by 4.68% and 4.01% per year from 1990 to 2021, respectively. Joinpoint regression analysis showed that global age-standardized prevalence of cystic echinococcosis appeared a tendency towards a decline from 1990 to 2000 [annual percent change (APC) = −0.66%, 95% confidence interval (CI): (−0.70%, −0.61%)] and from 2005 to 2015 [APC = −0.88%, 95% CI: (−0.93%, −0.82%)], and towards a rise from 2000 to 2005 [APC = 3.68%, 95% CI: (3.49%, 3.87%)] and from 2015 to 2021 [APC=0.30%, 95%CI: (0.19%, 0.40%)].Theagestandardized prevalence (r = −0.17, P < 0.05), mortality (r = −0.67, P < 0.05) and DALYs rates of cystic echinococcosis (r = −0.60, P < 0.05) all correlated negatively with SDI across 21 geographical regions from 1990 to 2021, and the age-standardized mortality (r = −0.61, P < 0.05) and DALYs rates (r = −0.44, P < 0.05) both correlated negatively with SDI across 204 countries and territories in 2021. Frontier analysis revealed that the age-standardized DALYs rate of cystic echinococcosis was still not in line with the frontier in some high-SDI countries or territories. In addition, the global age-standardized prevalence was projected with the BAPC model to appear a tendency towards a rise among both men [estimated annual percent change (EAPC) = 0.18%, 95% CI: (0.13%, 0.23%)] and women [EAPC = 0.29%, 95% CI: (0.24%, 0.34%)] from 2022 to 2035, and the global age-standardized mortality [men: EAPC = −4.71%, 95% CI: (−4.71%, −4.37%); women: EAPC = −4.74%, 95% CI: (−4.74%, −4.74%)] and DALYs rates [men: EAPC = −3.35%, 95% CI: (−3.36%, −3.34%); women: EAPC = −3.17%, 95% CI: (−3.18%, −3.16%)] were projected to appear a tendency towards a decline among both men and women. Conclusions The global burden of cystic echinococcosis appeared an overall tendency towards a decline from 1990 to 2021; however, the global prevalence of cystic echinococcosis is projected to appear a tendency towards a rise from 2022 to 2035. Intensified cystic echinococcosis control programmes are recommended.

Objective To explore the experience and causes of self-neglect of elderly diabetic patients in community,so as to provide references for community nursing workers to identify and intervene the self-neglect behavior of elderly diabetic patients.Methods An interpretative phenomenological method was used to collect data from elderly diabetic patients registered in 3 community health service centers in Hangzhou,Zhejiang Province through semi-structured interviews.Van Manen's method was used to analyze qualitative data.Results The experience and reasons of self-neglect of elderly diabetic patients in community were summarized into 4 themes and 10 sub-themes,including neglecting personal health(low sense of self-worth,high level of self-esteem,being afraid of compromising the family),neglecting blood glucose management(weak health awareness,difficulty in blood glucose management),inadequate self-care capacity(poor financial situation,insufficient personal time,diminished mobility)and inadequate perceived support(low social support,insufficient emotional support).Conclusion The experience and reasons of self-neglect of elderly diabetic patients in community are diversified.Community health services and nursing workers should pay attention to the performance of self-neglect behavior of elderly diabetic patients and actively explore effective prevention and intervention measures.

Objective:To screen differentially expressed circular RNA (circRNA) in rat articular chondrocyte injury induced by T-2 toxin, and explore the mechanism of cartilage injury.Methods:Twenty-four SD rats (males, body weight 60 - 80 g) were randomly divided into T-2 toxin group (administrated T-2 toxin 100 ng·g -1·d -1 by gavage) and control group (administrated equal amounts of deionized water by gavage) using a random number table method, 12 rats in each group. After 4 weeks of intervention, the articular cartilage was collected for transcriptome sequencing. Deseq2 software [ P < 0.05 and |log 2(fold change)| > 1, fold change was the multiple of differential expression] was used to identify differentially expressed circRNA. Based on the competing endogenous RNAs (ceRNA) hypothesis, the miRanda software was used to predict the microRNA (miRNA, miR) binding sites of differentially expressed circRNA, and Cytoscape 3.10.0 software was used to plot the circRNA-miRNA interaction network. MiRWalk 3.0, MiRDB, and miRTarBase softwares were used to predict downstream target genes, and Cytoscape 3.10.0 software was used to map the circRNA-miRNA-mRNA interaction network. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were used to analyze the biological functions and enrichment pathways of target genes. Results:A total of 19 differentially expressed circRNAs were screened (including 10 upregulated and 9 downregulated). A total of 1 320 miRNAs binding sites and 16 target genes were predicted. Target gene enrichment analysis revealed significant enrichment of mitogen-activated protein kinase (MAPK) and nuclear factor kappa-B (NF-κB) signaling pathway ( P < 0.05). Tumour necrosis factor receptor-associated factor 6 (Traf6) and interleukin-1 receptor-associated kinase 1 (Irak1) were enriched in the MAPK and NF-κB signaling pathways, with corresponding miRNA and circRNA of miR-146a-5p and chr2: 94716330|94720889. Conclusion:Nineteen differentially expressed circRNAs in rat articular chondrocyte injury are successfully screened, and chr2: 94716330|94720889 may regulate the MAPK and NF-κB signaling pathways through the miR-146a-5p/Traf6/Irak1 axis, inducing articular chondrocyte injury.

Colorectal cancer (CRC) is a prevalent malignant tumor often leading to liver metastasis and mortality. Despite some success with PD-1/PD-L1 immunotherapy, the response rate for colon cancer patients remains relatively low. This is closely related to the immunosuppressive tumor microenvironment mediated by tumor-associated macrophages (TAMs). Our previous work identified that a phosphoglycerate mutase 1 (PGAM1) allosteric inhibitor, HKB99, exerts a range of anti-tumor activities in lung cancer. Here, we found that upregulation of PGAM1 correlates with increased levels of M2-like tumor-associated macrophages (TAMs) in human colon cancer samples, particularly in liver metastatic tissues. HKB99 suppressed tumor growth and metastasis in cell culture and syngeneic tumor models. M2-polarization, induced by colon cancer cell co-culture, was reversed by HKB99. Conversely, the increased migration of colon cancer cells by M2-TAMs was remarkably restrained by HKB99. Notably, a decrease in TAM infiltration was required for the HKB99-mediated anti-tumor effect, along with an increase in CD8⁺ T cell infiltration. Moreover, HKB99 improved the efficacy of anti-PD-1 treatment in syngeneic tumors. Overall, this study highlights HKB99's inhibitory activity in TAM-mediated colon cancer progression. Targeting PGAM1 could lead to novel therapeutic strategies and enhance the effectiveness of existing immunotherapies for colon cancer.

Objective·To investigate the causal relationship between atrial fibrillation(AF)and cognitive impairment.Methods·A two-sample Mendelian randomization(TSMR)analysis was used to assess the potential causality of AF on cognitive dysfunction.Single nucleotide polymorphisms(SNPs)strongly associated with AF were extracted as instrumental variables by using a dataset of a large-scale genome-wide association study(GWAS)on AF.The associations of SNPs with Alzheimer's disease dementia,Parkinson's disease dementia,vascular dementia,Lewy body dementia,frontotemporal dementia,undefined dementia,and overall cognitive function assessment were extracted separately from publicly available GWAS data on cognitive dysfunction.The inverse variance-weighted(IVW)method was used for the main analysis,and sensitivity analyses were conducted by using Cochran's Q test,MR-Egger regression,and leave-one-out method.To verify the robustness of the results,replicate analyses and meta-analyses were performed by using different GWAS data.Results·In the initial analysis,101 SNPs were extracted as instrumental variables from a meta-analysis of a genome-wide association study involving up to 1 030 836 individuals.The IVW analysis showed no evidence for causal associations between AF and dementia[dementia(OR=1.032;95％CI 0.973-1.094;P=0.290),Parkinson's disease dementia(OR=1.004;95％CI 0.780-1.291;P=0.977),vascular dementia(OR=1.123;95％CI 0.969-1.301;P=0.125),or unspecified dementia(OR=1.013;95％CI 0.910-1.129;P=0.807)].In the replication analysis,27 SNPs were extracted as instrumental variables from the FinnGen AF GWAS data,and the 1VW analysis were consistent with the initial analysis[cognitive function(OR=0.999;95％CI 0.982-1.016;P=0.874),Alzheimer's disease dementia(OR=0.977;95％CI 0.943-1.012;P=0.193),Lewy body dementia(OR=1.014;95％CI 0.898-1.145;P=0.826),or frontotemporal dementia(OR=0.996;95％CI 0.745-1.333;P=0.980)].Both Mendelian randomization analyses and meta-analyses showed no evidence of an association between genetically predicted AF and different types of dementia or overall cognitive function assessment.MR-Egger regression suggested no horizontal pleiotropy and leave-one-out analysis showed stable results after individually removing each SNP.Conclusion·No evidence of a causal relationship between AF and cognitive impairment was found.The associations observed in observational studies can be partially attributed to confounding factors such as shared biology or co-morbidities.

Objective:To summarize the clinical features, treatments and prognoses of aggressive natural killer cell leukemia (ANKL) in children.Methods:Clinical data and follow-up results were retrospectively reviewed for one hospitalized case of ANKL in June 2019.Through a literature search, the relevant items were retrieved from the databases of China National Knowledge Infrastructure, WanFang and PubMed using the Chinese and English keywords of "aggressive natural killer cell leukemia" and "children" up to December 2021.Results:This 8-year-old girl was diagnosed with ANKL by flow cytometric immunophenotype and immunohistochemical stain.Fever was the initial manifestation accompanied by sallow complexion, fatigue, enlargement of liver, spleen and lymph node and hematopenia of three lines.Allogeneic hematopoietic stem cell transplantation (allo-HSCT) was performed after chemotherapy.As of April 2022, the child stayed in a disease-free survival state after follow-ups for over 2 years.The literature search finally yielded 7 eligible Chinese and 10 English reports with a total of 17 pediatric ANKLs.In this group, there were fever (n=15), rash (n=1), perineal mass (n=1) and diarrhea, vomiting and other digestive tract symptoms (n=1). Six cases were misdiagnosed during an early stage of disease.4 cases received chemotherapy alone, 3 cases received chemotherapy regimen for acute lymphoblastic leukemia, 1 child died and one death occurred after received chemotherapy regimen of "cisplatin + vincristine + doxorubicin + ifosfamide". Allo-HSCT was performed in 5 patients after remission with chemotherapy and one child died from multiple organ failure at 9 months after allo-HSCT.Nine cases gave up treatment.Conclusions:ANKL has a rapid disease progression, diverse clinical manifestations, easy misdiagnosis and poor prognosis.For suspected ANKL cases, clinicians perform multiple bone perforations at multiple sites and immunophenotype by flow cytometry as soon as possible to confirm the diagnosis.Currently allo-HSCT offers a long-term survival of ANKL patients.

Objective:To investigated the prevalence of anxiety and depression symptoms in patients with colorectal polyps in part of Xinjiang area and to explore the associated influencing factors related to psychological status, and to provide evidence and clues to promote the diagnosis and treatment of psychosomatic diseases in digestive system.Methods:From December 2021 to June 2022, at the First Affiliated Hospital of Shihezi University, the Fourth Division Hospital of Xinjiang Production and Construction Corps, the Third Division Hospital of Xinjiang Production and Construction Corps (Kashgar Hospital), the Thirteenth Division Red Star Hospital of Xinjiang Production and Construction Corps, the Tenth Division Beitun Hospital of Xinjiang Production and Construction Corps, the Seventh Division Hospital of Xinjiang Production and Construction Corps, the Fifth Division Hospital of Xinjiang Production and Construction Corps, patients who underwent colonoscopy and colorectal polyps detected were enrolled. The generalized anxiety disorder scale-7 (GAD-7) was used to screen anxiety symptoms, and the patient health questionaire-8 (PHQ-8) was performed to screen depression symptoms, and the general situation questionnaire was used to collect clinical information of patients. The questionnairs were completed via the Questionnaire Star platform or paper questionnaire, and a database was established. The patients were divided into groups according to whether with anxiety and depression symptoms. Multivariable logistic regression models was performed to analyze the factors related to anxiety and depression.Results:A total of 516 questionnaires were distributed and collected, among which 9 questionnaires were incomplete and 507 questionnaires were valid, the effective rate of questionnaires was 98.26%. The detection rates of anxiety and depression symptoms in 507 patients with colorectal polyps were 21.50%(109/507) and 19.33%(98/507), respectively. The results of multivariable logistic analysis revealed that female ( OR=3.87, 95% confidence interval (95% CI) 2.30 to 6.51, P<0.001), maximum diameter of polyp ( OR=1.74, 95% CI 1.14 to 2.67, P=0.011), perception of polyps as cancer ( OR=13.96, 95% CI 1.48 to 132.07, P=0.022), and the occurrence of gastrointestinal symptoms after polyp detection ( OR=5.43, 95% CI 1.74 to 16.92, P=0.004) were independent risk factors of anxiety in patients with colorectal polyps. Female ( OR=2.42, 95% CI 1.47 to 4.00, P=0.001), the number of polyps ( OR=1.07, 95% CI 1.01 to 1.13, P=0.028) and the count of gastrointestinal symptoms ( OR=2.04, 95% CI 1.34 to 3.10, P=0.001) were independent risk factors of depression in patients with colorectal polyps. Conclusion:Gender, polyp size, number of polyps, disease perception, and concomitant gastrointestinal symptoms are associated with anxiety and depression in patients with colorectal polyps.

Objective:To explore the clinical effects of a series of posture intervention strategies on correcting abnormal fetal position, so as to provide a basis for Clinical position management and promotion of natural delivery.Methods:This study was a randomized controlled trial. The convenience sampling method was used to select 196 full-term primiparas women with abnormal fetal orientation confirmed by ultrasound as single fetal head position in the Women′s Hospital, School of Medicine, Zhejiang University from March to October 2022 as the research objects. They were divided into control group 106 cases and research group 90 cases by random number table method. The control group received normal nursing and chose comfortable position by themselves during labor. The research group received a series of ultrasound-guided postural intervention strategies for postural management in the first and second stages of labor on the basis of normal nursing. The angle of progression and the midline angle, the fetal orientation, fetal orientation during complete uterine orifice and delivery outcome were compared between the two groups.Results:Finally, 190 cases were included, 105 cases in the control group and 85 cases in the research group. There were 76 vaginal deliveries in the research group and 95 in the control group. The rate of anterior occipital position and the angle of fetal head rotation in the research group were 73.68% (56/76) and 64.55 (37.90, 85.55)°, which were higher than 45.26% (43/95) and 33.00 (14.00, 60.00)° in the control group;the midline angle of the research group was 57.10(38.50, 75.80)°, which was lower than 80.00 (52.50, 90.30)° of the control group. There was significant difference between the two groups ( χ2 = 14.14, Z = 4.17, - 3.74, all P<0.01). The first stage of labor was 522.50 (413.00, 695.00) minutes and the total stage of labor was 611.00 (488.00, 812.00) minutes in the research group, which was lower than 620.00 (450.00, 795.00) and 700.00 (539.00, 904.00) minutes in the control group ( Z = - 2.34, - 2.03, both P<0.05). Conclusions:The application of the serial position intervention strategy under the ultrasound guidance during the labor process can improve the abnormal fetal position, shorten the first stage of labor time effectively and safely, while it does not have any significant effect on the improvement of the delivery outcome.

Objective:To investigate the clinical efficacy of redo rectal resection and coloanal anastomosis.Methods:The retrospective and descriptive study was conducted. The clinicopatholo-gical data of 49 patients who underwent redo rectal resection and coloanal anastomosis for the treatment of local recurrence of tumors and failure of colorectal or coloanal anastomosis after rectal resection in the Sixth Affiliated Hospital of Sun Yat-sen University from November 2012 to December 2021 were collected. There were 32 males and 17 females, aged 57(range,31-87)years. Redo rectal resection and coloanal anastomosis was performed according to the patient′s situations. Observa-tion indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distri-bution were represented as M( Q1, Q3) or M(range). Count data were described as absolute numbers or percentages. Results:(1) Surgical situations. All 49 patients underwent redo rectal resection and coloanal anastomosis successfully, with the interval between the initial surgery and the reopera-tion as 14.2(7.1,24.3)months. The operation time and volume of intraoperative bold loss of 49 patients in the redo rectal resection and coloanal anastomosis was 313(251,398)minutes and 125(50,400)mL, respectively. Of the 49 patients, there were 38 cases receiving laparoscopic surgery including 12 cases with transanoscopic laparoscopic assisted surgery, 11 cases receiving open surgery including 2 cases as conversion to open surgery, there were 20 cases undergoing Bacon surgery, 14 cases undergoing Dixon surgery, 12 cases undergoing Parks surgery, 2 cases undergoing intersphincter resection and 1 case undergoing Kraske surgery, there were 20 cases undergoing rectum dragging out excision and secondary colonic anastomosis, 13 cases undergoing dragging out excision single anastomosis, 12 cases undergoing rectum dragging out excision double anastomosis, 4 cases undergoing first-stage manual anastomosis, there were 21 cases with enterostomy before surgery, 16 cases with prophylactic enterostomy after surgery, 12 cases without prophylactic enterostomy after surgery. The duration of postoperative hospital stay of 49 patients was (14±7)days. (2) Postoperative situations. Fifteen of 49 patients underwent postoperative complications, including 8 cases with grade Ⅱ Clevien-Dindo complications and 7 cases with ≥grade Ⅲ Clevien-Dindo complications. None of 49 patient underwent postoperative transferring to intensive care unit and no patient died during hospitalization. Results of postoperative histopathological examination in 23 patients with tumor local recurrence showed negative incision margin of the surgical specimen. (3) Follow-up. All 49 patients underwent post-operative follow-up of 90 days. There were 42 cases undergoing redo rectal resection and coloanal anastomosis successfully and 7 cases failed. Of the 37 patients with enterostomy, 20 cases failed in closing fistula, and 17 cases succeed. There were 46 patients receiving follow-up with the median time as 16.1(7.5,34.6)months. The questionnaire response rate for low anterior resection syndrome (LARS) score was 48.3%(14/29). Of the patients who underwent redo coloanal anastomosis and closure of stoma successfully, there were 9 cases with mild-to-moderate LARS.Conclusion:Redo rectal resection and coloanal anastomosis is safe and feasible for patients undergoing local recurr-ence of tumors and failure of colorectal or coloanal anastomosis after rectal resection, which can successfully restore intestinal continuity in patients and avoid permanent enterostomy.
