Diabetes of the exocrine pancreas(DEP) refers to a complication of diseases of the exocrine pancreas, associated with an increased risk of pancreatic cancer. Recent evidence has indicated that DEP, after type 2 diabetes, has become the second most common type of adults-onset diabetes, with a higher prevalence than type 1 diabetes. DEP is not a single condition but encompasses various exocrine pancreatic disorders that lead to hyperglycemia through different mechanisms, creating significant diagnostic and therapeutic challenges. This review examines the latest research on the risk factors and pathogenesis of DEP, aiming to provide insights to improve its clinical management strategies.

OBJECTIVE To investigate the quality and management of cleaning and disinfection of soft endoscopes in Wuxi hospitals,to analyze the existing problems and put forward suggestions for improvement,and to provide references for endoscope-related infection in hospitals.METHODS From Sep.to Nov.2024,the cleaning and disin-fection status and managements of soft endoscopes were investigated.Endoscopes were sampling for adenosine triphosphate(ATP)biofluorescence and bacteriological testing;final rinsing water,hands of disinfection person-nels,disinfectants and environmental surfaces were collected for bacteriological testing.RESULTS Totally 68.18％of hospitals performed daily leaks test before cleaning,and 81.82％used o-Phthalaldehyde;81.25％of hospitals used peracetic acid in endoscopy sterilization,with only 1 hospital using glutaraldehyde.Totally 86.36％of hospi-tals monitored the concentration of disinfectants before daily works.There were statistically significant differ-ences in full-time,education levels,age and working experience of personnels among different levels of hospitals(P＜0.05).The pass rate of the 60 endoscope ATP specimens was 88.33％,and there were statistically signifi-cant differences in the pass rate of gastroscopic ATP testing among different levels of hospitals(P=0.032).The qualification status differed significantly in the types of endoscopes and the time length of enzyme washing(P＜0.05).All 60 endoscopic bacteriological samples were qualified,while 141 environmental bacteriological samples were with a pass rate of 94.33％.Unqualified samples were mainly for disinfection personnel's hands,rinse tank faucets,final rinse water.Rolestonella piercei and Staphylococcus wolffii were detected in one failed final rinse wa-ter by mass spectrometry.CONCLUSIONS The overall equipment and staffing of the surveyed endoscope centers(rooms)basically meet operational needs and generally follow endoscope cleaning and disinfection guidelines.However,there are still deficiencies in cleaning and disinfection management,equipment maintenance,disinfect-ant concentration monitoring and personnel training.Further efforts are needed to strengthen the disinfection quali-ty monitoring of endoscope and related factors.

Objective Currently, there is no commercially available quantitative detection kit for the main Felis domestic allergen (Fel d 1) in China. To establish a rapid detection method for Fel d 1, this study aims to prepare monoclonal antibodies against Fel d 1 protein. Methods The codon preference of Escherichia coli was utilized to optimize and synthesize the Fel d 1 gene. The prokaryotic expression plasmid pET-28a-Fel d 1 was constructed and used to express and purify the recombinant Fel d 1 protein. Subsequently, the recombinant protein was immunized into BALB/c mice and monoclonal antibodies (mAbs) were prepared by the hybridoma technique. An indirect ELISA was established using the recombinant Fel d 1 as the coating antigen, and hybridoma cell lines were screened for positive clones. The specificity and antigenic epitopes of the mAbs were confirmed by Western blot analysis. Finally, the selected hybridoma cells were injected into the peritoneal cavities of BALB/c mice for large-scale monoclonal antibody production. Results The recombinant plasmid pET-28a-Fel d 1 was successfully constructed, and soluble Fel d 1 protein was obtained after optimizing the expression conditions. Western blot and antibody titer assays confirmed the successful isolation of two hybridoma cell lines, 7D11 and 5H4, which stably secreted mAbs specific to Fel d 1. Antibody characterization revealed that the 5H4 mAb was of the IgG2a subtype and could recognize the amino acid region 105-163 of Fel d 1, while the 7D11 mAb was the IgG1 subtype and could recognize the amino acid region 1-59. Conclusion The high-purity recombinant Fel d 1 protein produced in this study provides a promising alternative for clinical immunotherapy of cat allergies. Furthermore, the monoclonal antibody prepared in this experiment lays a material foundation for the in-depth study of the biological function of Fel d 1 and the development of ELISA detection.

Chronic obstructive pulmonary disease(COPD)has become a common chronic disease in the adult in recent years,and more attention has been gradually paid to its prevention and treatment.This paper reviewed the clinical studies about the effect of traditional Chinese medicine(TCM)exercise therapy on COPD,and indicated that TCM exercise therapy can improve the rehabilitation of COPD patients.TCM exercise therapies,such as Tai Chi,Wuqinxi,Baduanjin,and Liuzijue,have been shown to significantly improve lung function,inflammation levels,and exercise capacity in COPD patients in recent studies.Tai Chi significantly improves patient's respiratory problems although lung function indices are not changed.Liuzijue enhances the strength and endurance of respiratory muscles and limbs.Baduanjin helps to improve patient's cognitive and emotional states.Overall,TCM exercise therapy provides an effective rehabilitation option for COPD patients.However,more clinical controlled trials are needed to further confirm their effectiveness and to develop appropriate rehabilitation programs for COPD patients.

Objective To systematically analyze the clinical pharmaceutical rehabilitation model based on data mining,so as to explore its role in improving drug treatment efficacy,reducing drug side effects,and optimizing rehabilitation experience.Methods We retrieved published literatures related to clinical pharmaceutical rehabilitation from CNKI,Wanfang,VIP,and PubMed,with a search time from inception to June 30,2022.Results Totally 11 articles were enrolled in this study.A study involving 69 randomized controlled trials(RCTs)demonstrated that the involvement of pharmacists in medication reviews significantly improved the control of hypertension,type 2 diabetes,and high cholesterol.The odds ratio(OR)for improved control was 2.71(95%confidence interval[CI]:1.03-7.01)for hypertension,3.12(95%CI:1.12-5.84)for type 2 diabetes,and 1.90(95%CI:1.05-3.35)for high cholesterol.A study involving 6 RCTs and 2 573 patients with chronic kidney disease(CKD)showed that pharmacist-led blood pressure monitoring,lifestyle,and medication regimen assessments significantly improved blood pressure control in CKD patients,with an OR of 1.51(95%CI:1.13-2.03).A Meta-analysis,including 5 RCTs and 3 observational studies,explored the impact of medication education and behavioral interventions on the treatment outcomes of gout.The results revealed that patients receiving medication education and behavioral interventions had a significantly higher rate of uric acid control and a higher proportion of patient with uric acid less than 360 μmol/L.A Meta-analysis of 14 RCTs involving 4 509 patients showed that pharmacist interventions such as medication education and counseling significantly reduced the 30-day readmission rates for hypertension and diabetes patients,with a relative risk(RR)of 0.75(95%CI:0.53-0.96).Eighteen RCTs involving 7 244 patients investigated the impact of pharmacist-led discharge counseling on the readmission rate.The findings showed that discharge counseling significantly reduced readmission rate,with a RR of 0.864(95%CI:0.763-0.997,P=0.020).Eight studies assessed the impact of pharmacist services on readmission rate,and the result showed that patients receiving pharmacy-related services had significantly reduced readmission rates,with a 32%reduction in the risk of readmission(OR=0.74,95%CI:0.62-0.89).A Meta-analysis including 123 studies investigated the effect of pharmacist interventions in patient care on the readmission rate,and the result indicated that pharmacist interventions led to a decrease in readmission rates,with the maximum decrease of 44.5%.A Meta-analysis of 23 RCTs evaluated the impact of pharmacist interventions on medication-related adverse events in elderly residents of nursing homes.The study found that pharmacist-led medication reviews and education significantly reduced adverse events.Another Meta-analysis of 14 RCTs and intervention studies explored the effect of pharmacist involvement in multidisciplinary care on medication-related adverse events.The analysis showed that pharmacist participation in multidisciplinary care was significantly associated with a reduction in the incidence of adverse events(RR=0.47,95%CI:0.28-0.77,P<0.01).A Meta-analysis of 6 RCTs involving 29 291 pediatric inpatients revealed that pharmacist interventions effectively reduced the risk of medication errors in hospitalized children(OR=0.27,95%CI:0.15-0.49).A literature analysis on the effectiveness of clinical pharmaceutical services in patient drug treatment showed that introducing a clinical pharmaceutical service model can reduce the use of antibiotics,lower medical costs,and improve medication satisfaction among patients treated with antibiotics.Conclusion In-depth exploration of clinical pharmaceutical rehabilitation model plays an important role in clinical treatment,which can improve the effectiveness of rehabilitation and reduce the incidence of adverse reactions.

Recently,small nucleolar RNAs(snoRNAs)have transcended the genomic"noise"to emerge as pivotal molecular markers due to their essential roles in tumor progression.Substantial evidence indicates a strong association between snoRNAs and critical clinical features such as tumor pathology and drug resistance.Historically,snoRNA research has concentrated on two classical mechanisms:2'-O-ribose methylation and pseudouridylation.This review specifically summarizes the novel regulatory mecha-nisms and functional patterns of snoRNAs in tumors,encompassing transcriptional,post-transcriptional,and post-translational regulation.We further discuss the synergistic effect between snoRNA host genes(SNHGs)and snoRNAs in tumor progression.More importantly,snoRNAs extensively contribute to the development of tumor cell resistance as oncogenes or tumor suppressor genes.Accordingly,we provide a comprehensive review of the clinical diagnosis and treatment associated with snoRNAs and explore their significant potential as novel drug targets.
