Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder affecting multiple systems, characterized by the development of harmful autoantibodies and immune complexes that lead to damage in organs and tissues. Chinese medicine (CM) plays a role in mitigating complications, enhancing treatment effectiveness, and reducing toxicity of concurrent medications, and ensuring a safe pregnancy. However, CM mainly solves the disease comprehensively through multi-target and multi-channel regulation process, therefore, its treatment mechanism is often complicated, involving many molecular links. This review introduces the research progress of pathogenesis of SLE from the aspects of genetics, epigenetics, innate immunity and acquired immunity, and then discusses the molecular mechanism and target of single Chinese herbal medicine and prescription that are commonly used and effective in clinic to treat SLE.

Objective To understand the current status of application,management,and maintenance of automa-ted endoscope reprocessors(AERs)in China.Methods A questionnaire survey was conducted using convenience sampling method on the application,management,maintenance,and monitoring of AERs,as well as personnel training in digestive endoscopy centers of 292 medical institutions(MIs).Results A total of 316 questionnaires were distributed,and 292 were available,with an effective response rate of 92.41％.Among the 292 MIs,198(67.81％)were equipped with AERs,with equipment rates of 75.11％in tertiary MIs and 41.27％in secondary MIs.88.38％of MIs performed manual cleaning before placing endoscopes into AERs,while 2.02％of MIs still didn't perform this step,mainly in tertiary MIs.The most common problems in the application of AERs were the detachment or damage of connecting pipes(83.33％),followed by disinfectant leakage of AERs(43.94％),mal-function of control panel(43.94％),and failure or poor water flow of AER pipeline(42.93％).92.42％of MIs regularly disinfected AERs,72.73％of MIs regularly replaced AER air filters,and 80.30％of MIs regularly re-placed AER water filters.96.46％of MIs monitored the concentration of disinfectants before daily application of AERs,87.88％of MIs regularly monitored the final rinse water of AERs,and 96.97％of MIs provided professio-nal training for new employees to use AERs for the first time.Conclusion The equipping rate of AERs at all levels of MIs in China still needs to be improved.Most MIs are able to monitor and maintain AERs well,but there are still many problems in the application process.Due to the large volume of endoscopic diagnosis and treatment as well as insufficient execution rate of manual cleaning in tertiary MIs,it is necessary to optimize workflow and strengthen training.Secondary MIs face challenges such as equipment shortages and low monitoring execution rates,requiring increased funding and regulatory efforts.It is recommended that manufacturers continuously optimize AER design,MIs establish standardized AER application protocol,and relevant departments improve AER application and ma-nagement standards,in order to improve the quality of endoscopic cleaning and disinfection and ensure patient safety during diagnosis and treatment.

Objective To compare the effectiveness of cobalt chloride test papers and borescope in evaluating the drying of endoscopes,providing a reference for clinical selection of appropriate assessment tools.Methods 10 gastroscopes and 10 colonoscopes procedures were selected from November 2023 to March 2024 for circulation experiments.After endoscope reprocessing,they were randomly divided into five groups with different drying times(30 s,3 min,6 min,9 min,and 12 min)with 200 samples.Cobalt chloride test paper and borescope were used to evaluate the drying effectiveness.Results The qualified rate of gastrointestinal endoscope by borescope was significantly higher than that by cobalt chloride test paper,but cobalt chloride test paper was obviously better than that by borescope in convenience and cost-effectiveness.The borescope had the function of visualization,and the quantitative positioning observation of residual droplets showed that there were a large number of droplets left after gastrointestinal endoscope drying for 30 s,and the number of droplets was obviously reduced after drying for 3 min.Among them,the gastroscope was mainly light(1～5 drops/strip)and none(0 drops/strip),and the colonoscope was mainly moderate(6～10 drops/strip)and light droplets.Compared with different drying times,there was a significant statistical difference in the number of residual droplets in the endoscope(P<0.01),and the localized droplets mainly remained in the distal bending part and the proximal bifurcation part of the lumen.Conclusion Both cobalt chloride test papers and borescope are important methods for assessing endoscope drying efficacy,each with its own advantages and limitations.Clinicians can use both methods in combination to comprehensively evaluate the overall dryness of endoscopes,thereby ensuring the safety and effectiveness of the endoscope reprocessing process.

Chikungunya fever(CHIKF)is a mosquito-borne infectious disease caused by Chikungunya virus(CHIKV)infection,which has become a significant public health threat of global concern in recent years.The acute phase of CHIKF is primarily characterized by sudden high fever,severe polyarthralgia,and rash.The disabling arthralgia may progress to chronic arthritis,with symptoms lasting for months or even years.This not only severely reduces patients'quality of life and impairs their labor capacity,but also imposes a heavy socioeconomic burden.In recent years,significant progress has been made in CHIKF-related research.This review elaborates on the latest research achievements in the fields of the disease's epidemiology,clinical manifestations,pathogenic mechanisms,immune response,diagnostic techniques,and prevention and treatment strategies,aiming to provide comprehensive and in-depth references for researchers and clinicians in relevant fields.

In this work,a fluorescent probe PIN was synthesized using indole-3-carbohydrazide and pyrenecarboxaldehyde as raw materials.PIN showed weak fluorescence emission in aqueous solution with acetonitrile volume fraction of 70％.However,when Cu2+was added to this aqueous solution of PIN,a new fluorescence emission peak appeared at 495 nm,and the intensity of this peak gradually increased with the increase of concentration of Cu2+,and also caused a significant change in the fluorescence color of the solution.In contrast,the addition of 15 kinds of other common metal ions did not cause such change.The detection limit of PIN for Cu2+was 78.7 nmol/L,which was much lower than the maximum permitting level of Cu2+in drinking water in hygienic standard for drinking water in China.Therefore,PIN was a highly selective and sensitive fluorescence-enhanced probe for Cu2+.Meanwhile,the addition of Cu2+could also cause a new absorption peak at 440 nm in the ultraviolet-visible absorption spectrum of the aqueous solution of PIN,and meanwhile the colorless PIN solution changed into yellow,exhibiting the performance of PIN as a colorimetric probe for Cu2+.By fitting with the Levenberg-Marquardt algorithm equation,the binding ratio of PIN to Cu2+was 2:1,and the binding constant was 3.42×1012 L2/mol2.In addition,the binding mode of PIN with Cu2+was explored by using proton nuclear magnetic resonance(1H NMR)titration experiments and density functional theory simulations.The results showed that the addition of Cu2+could cause the aggregation of PIN molecules to form excimers,thus showing highly selective recognition.Finally,PIN was made into a simple test strip,which could achieve rapid and convenient fluorescence detection of Cu2+in actual water samples.

Objective To investigate the bacterial contamination of water specimens at different pre-discharge time of flexible endoscopic final rinse water before daily use,and provide reference basis for choosing the optimal pre-dis-charge time in clinical work.Methods From August to December 2023,the water produced by the purified water equipment of the digestive endoscopy centers of 4 tertiary first-class medical institutions in Jiangxi Province,as well as the final rinsing water at the terminal-point at different pre-discharge times(before pre-discharge,discharge of 1,3,5,and 10 minutes)were subjected to on-site sampling,the collected water specimens were performed microbio-logical cultures by pouring and filter membrane methods,unqualified water specimens were performed bacterial i-dentification.Results 48 specimens of water produced by purified water equipment were collected,with qualified rate of 100％.480 final water specimens were collected,with a qualified rate of 0 before pre-discharge.The quali-fied rates of pre-discharge at 1,3,5,and 10 minutes were 0,21.88％,55.21％,and 73.96％,respectively.Bac-terial colony counts in the final rinse water with different pre-discharge times in 4 medical institutions showed statis-tically significant differences(all P＜0.001).As the pre-discharge time increased,bacterial colony counts in the fi-nal rinse water of all four medical institutions showed a decreasing trend.The pairwise comparison of the overall bacterial colony count of the final rinse water at different pre-discharge time showed that there was no statistically significant difference in the bacterial colony count of the final rinse water at 5 and 10 minutes of pre-discharge(P＞0.05),while the pairwise comparison between other time points showed statistically significant differences(all P＜0.001).Environmental contaminated bacteria such as Micrococcus luteus,Cupriavidus paucula,and Sphin-gononas paucimobilis were detected from the unqualified water specimens.Conclusion With the extension of pre-discharge time,the degree of bacterial contamination in the final rinse water significantly decreases.All levels of medical institutions need to pre-discharge the final rinse water daily,and the pre-discharge time should last for at least 5 minutes.
