OBJECTIVE To analyze the components migrating to blood and metabolites of Polygonum cuspidatum in rats with acute gouty arthritis （AGA）. METHODS SD rats were randomly divided into blank group， model group and P. cuspidatum group （10 g/kg， by raw material）， with 6 rats in each group. Except for blank group， AGA model was induced in the remaining groups by injecting potassium oxonate and sodium urate； meanwhile， they were administered corresponding drug solutions or water intragastrically， once a day， for 10 consecutive days. The histopathological morphology of the knee joint tissues in rats was observed；rat serum samples were collected， and the components migrating to blood and metabolites of P. cuspidatum were analyzed by using UPLC-Q-Exactive-Orbitrap-MS. RESULTS Following the intervention with P. cuspidatum， the histopathological morphology of the knee joint synovial tissue in AGA rats showed significant improvement， with reduced inflammatory cell infiltration and hyperplasia， and the preservation of the honeycomb-like structure integrity. In both positive and negative ion modes， a total of 67 chemical components were detected in the serum of rats from P. cuspidatum group， including 25 prototype components and 42 metabolites. The involved compound types encompassed stilbenes， anthraquinones， naphthols， and flavonoids， among others. The metabolic reactions identified included methylation， acetylation， sulfation， and glucuronidation. Notably， compounds such as polydatin， resveratrol and emodin were capable of entering the bloodstream in their prototype forms and undergoing in vivo metabolism. CONCLUSIONS Compounds such as polydatin， resveratrol and emodin are likely to be the active components responsible for the anti-AGA effects of P. cuspidatum.

Primary ciliary dyskinesia (PCD) is a genetically heterogeneous disorder characterized by impaired motility of cilia and flagella. Mutations in cilia- and flagella-associated protein 300 ( CFAP300 ) are associated with human PCD and male infertility; however, the underlying pathogenic mechanisms remain poorly understood. In a consanguineous Chinese family, we identified a homozygous CFAP300 loss-of-function variant (c.304delC) in a proband presenting with classical PCD symptoms and severe sperm abnormalities, including dynein arm deficiency and acrosomal malformation, as confirmed by transmission electron microscopy (TEM). Histological analysis revealed multiple morphological abnormalities of the sperm flagella in CFAP300 -mutant individual, whereas immunofluorescence demonstrated markedly reduced CFAP300 expression in the spermatozoa of the proband. Furthermore, tandem mass tag (TMT)-based quantitative proteomics showed that the CFAP300 mutation reduced key spermatogenesis proteins (e.g., sperm flagellar 2 [SPEF2], solute carrier family 25 member 31 [SLC25A31], and A-kinase anchoring protein 3 [AKAP3]) and mitochondrial ATP synthesis factors (e.g., SLC25A31, cation channel sperm-associated 3 [CATSPER3]). It also triggered abnormal increases in autophagy-related proteins and signaling mediator phosphorylation. These molecular alterations are likely to contribute to progressive deterioration of sperm ultrastructure and function. Notably, successful pregnancy was achieved via intracytoplasmic sperm injection (ICSI) using the proband's sperm. Overall, this study expands the known CFAP300 mutational spectrum and offers novel mechanistic insights into its role in spermatogenesis.

OBJECTIVE: To assess the prognostic significance of plasma fibrinogen（FIB） levels in patients of diffuse large B-cell lymphoma(DLBCL). METHODS: We retrospectively analyzed 203 newly diagnosed with DLBCL patients who met the study requirements from November 2016 to May 2024. Based on the receiver operating characteristic (ROC) curve analysis of plasma FIB levels during diagnosis, the critical value of FIB was determined, and patients were divided into high FIB and low FIB groups. The clinical characteristics and relevant laboratory indicators of two groups were compared. The impact of plasma FIB levels on overall survival (OS) were evaluated using Kaplan-Meier curves as well as univariate and multivariate Cox regression analysis. The differences in FIB and other laboratory indicators under different disease states were compared. RESULTS: According to the ROC curve, the optimal cut-off value of FIB was 3.49 g/L. Compared with the high FIB group (>3.49 g/L), the low FIB group (≤3.49 g/L) had a significant decrease in neutrophil count (ANC) (P =0.001) and platelet count (PLT) (P =0.027), and a significant increase in prealbumin (PA) (P =0.001). A high FIB level was associated with decreased OS (P =0.005). Univariate analysis results showed that FIB had an impact on survival of patients(HR＝2.031，95%CI : 1.221-3.375, P =0.006). Multivariate analysis showed that higher FIB level was an independent adverse prognostic factor affecting patients survival （HR＝2.684， 95%CI :1.478-4.875, P =0.001）. Compared with patients with newly diagnosed or recurrent DLBCL, patients with complete remission showed a significant decrease in FIB (P _ND < 0.001, P _R=0.001) and ANC (P _ND < 0.001, P _R=0.021), as well as an increase in albumin (ALB) (P _ND < 0.001, P _R=0.018) and PA (P _ND < 0.001, P _R < 0.001). CONCLUSION Elevated FIB is a poor prognostic factor for DLBCL patients. The plasma FIB level is correlated with laboratory indicators such as ANC, PLT, PA, and disease status in DLBCL patients. Dynamic monitoring can assist in the early detection of changes in the condition.

BACKGROUND: The association of systemic inflammatory response index (SIRI) with prognosis of coronary artery disease (CAD) patients has never been investigated in a large sample with long-term follow-up. This study aimed to explore the association of SIRI with all-cause and cause-specific mortality in a nationally representative sample of CAD patients from United States. METHODS: A total of 3386 participants with CAD from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 were included in this study. Cox proportional hazards model, restricted cubic spline (RCS), and receiver operating characteristic curve (ROC) were performed to investigate the association of SIRI with all-cause and cause-specific mortality. Piece-wise linear regression and sensitivity analyses were also performed. RESULTS: During a median follow-up of 7.7 years, 1454 all-cause mortality occurred. After adjusting for confounding factors, higher lnSIRI was significantly associated with higher risk of all-cause (HR = 1.16, 95% CI: 1.09-1.23) and CVD mortality (HR = 1.17, 95% CI: 1.05-1.30) but not cancer mortality (HR = 1.17, 95% CI: 0.99-1.38). The associations of SIRI with all-cause and CVD mortality were detected as J-shaped with threshold values of 1.05935 and 1.122946 for SIRI, respectively. ROC curves showed that lnSIRI had robust predictive effect both in short and long terms. CONCLUSIONS SIRI was independently associated with all-cause and CVD mortality, and the dose-response relationship was J-shaped. SIRI might serve as a valid predictor for all-cause and CVD mortality both in the short and long terms.

Gynecological cancer significantly affect the health of women.This review aimed to describe the global patterns and trends in the survival of patients with gynecological cancers.We searched PubMed,Embase,Web of Science,SinoMed,and SEER for survival analyses of cancer registration data of cervical,endometrial,and ovarian cancers published between 1980 and 2022.Globally,the highest 5-year observed survival rate for cervical cancer was 76.5%in Anshan,Liaoning,China(2008-2017).The 5-year observed survival rates of endometrial and ovarian cancers were higher in Finland(1995-1999,82.5%)and Singapore(1988-1992,62.0%).The 5-year relative survival rate of cervical cancer patients was higher in Haining,Zhejiang,China(2011-2014,85.8%).Korea ranked first at 89.0%and 64.5%for endometrial and ovarian cancers,respectively.Survival rates have improved for cervical,endometrial,and ovarian cancers.Patients aged≥75 years and those with advanced-stage disease had the worst 5-year survival rates.Survival rates were better for squamous cell carcinoma in cervical cancer,for endometrial carcinoma and mucinous adenocarcinoma in endometrial cancer,and for germ cell and sex-cord stromal tumors in ovarian cancer.Over the past four decades,the survival rates of gynecological cancers have increased globally,with notable increases in cervical and endometrial cancers.Survival rates are higher in developed countries,with a slow-growing trend.Future studies should focus on improving survival,especially in ovarian cancer patients.

Objective To explore the factors that affect the coordinated development of blood banks and apheresis plas-ma collection banks(hereinafter referred to as plasma banks),and explore feasible measures for the coordinated develop-ment of blood banks and plasma banks.Methods The blood information management system and blood source information management system were used to retrieve related data of blood and plasma donation from 9 cities in Shandong province from 2017 to 2021.The number of blood donors and plasma donors and the intersection of them were analyzed.The data analysis was performed using chi-square test,and a questionnaire survey was conducted to investigate the policies and information status,as well as expectations for coordinated development for blood and plasma donation.Results From 2017 to 2021,the total number of blood donors in 9 cities was higher than that of plasma donors,both have been increasing year by year,and the increase in plasma donors was significantly higher than that of blood donors(131.78%vs 23.90%,P<0.05).The inter-section proportion of blood and plasma donors had increased from 0.45%in 2017 to 1.04%in 2021,with an increase of 131.11%.Among the administrative regions where the participating blood and plasma banks located,94.2%have not re-leased relevant policy to promote the coordinated development of blood and plasma donation.The majority(63%)expected blood banks and plasma banks to be set at a distance more than 50 km apart.The top four functional requirements for the in-terconnection between blood banks and plasma banks management information system were blood test results(94.61%),ID number(87.54%),blood and plasma donation records(85.51%)and health consultation/examination results(82.15%).The top four elements of coordinated development between blood and plasma banks were policy support(96.25%),informa-tion networking(92.36%),top-level design(87.44%)and cultural construction(86.58%).Conclusion The number of donors who donate both blood(mainly whole blood)and plasma has been increasing year by year,which deserves our close attention.To achieve the coordinated development of blood donation and plasma donation,policy support is the most crucial and fundamental means.Establishment of a standard system and the share of blood and plasma donation information is neces-sary for blood informatization construction.It was critical to promote the coordinated development of blood and plasma dona-tion and ensure blood safety with improving legislation,formulating policies for coordinated development,strengthening top-level design,standardizing the publicity of blood and plasma donation and establishing the idea that blood and plasma dona-tion are equally honorable.

Objective:To investigate the characteristics and distribution of monoclonal gammopathy in clinical patients.Methods:A total of 936 171 patients (508 449 males and 427 722 females) who received capillary zone electrophoresis in Zhongshan Hospital Affiliated to Fudan University from January 2012 to December 2021 were selected, from which 14 945 patients with abnormal bands were screened as the study subjects, including 10 173 males and 4 772 females and the age 21-102 (65±13) years old. According to the age, patients were divided into 8 groups: 21-30 years old (168 cases), 31-40 years old (405 cases), 41-50 years old (1 326 cases), 51-60 years old (3 068 cases), 61-70 years old (4 985 cases), 71-80 years old (3 288 cases), 81-90 years old (1 519 cases), and≥91 years old (186 cases). The diagnostic results of the 14 945 patients with abnormal bands were collected and were divided into tumor group (5 196 cases) and non-tumor disease group (9 749 cases) according to the presence of tumor. The distribution of abnormal bands in different gender, age, and disease groups were retrospectively analyzed. Among the 14 945 patients, 4 988 cases underwent immunofixation electrophoresis, excluding 336 negative cases and 412 cases of double clonal bands reaction, and 4 240 patients with monoclonal immunoglobulin (M protein) reaction were selected as the study subjects, including 2 794 males and 1 446 females aged 21-102 (67±12) years old. They were divided into 8 groups according to the age: 21-30 years old (18 cases), 31-40 years old (91 cases), 41-50 years old (364 cases), 51-60 years old (862 cases), 61-70 years old (1 455 cases), 71-80 years old (904 cases), 81-90 years old (486 cases), and≥91 years old (60 cases). The diagnostic results and immunoglobin subtypes (IgA-κ, IgA-λ, IgG-κ, IgG-λ, IgM-κ, IgM-λ, κ, λ) of patients were collected, and the distribution of monoclonal gammopathy in different gender, age and disease groups were retrospectively analyzed.Results:Among 936 171 patients, 14 945 cases showed abnormal bands in electropherograms with a detection rate of 1.60%; the detection rates of abnormal bands in males and females were 2.00% (10 173/508 449) and 1.12% (4 772/427 722), respectively, with a statistically significant difference ( P<0.01). There was a significant difference in the detection rate of abnormal bands among different age groups ( P<0.01); among them, the highest detection rate of abnormal band in group of ≥91 years old was 5.98%, and the ratio of male to female was 1.67∶1. Among the 14 945 cases of abnormal bands, patients aged 51-60, 61-70 and 71-80 accounted for 20.53% (3 068 cases), 33.36% (4 985 cases) and 22.00% (3 288 cases), respectively, and the differences among the age groups were statistically significant (χ 2=115.82, P<0.01). In the tumor group, the top 3 tumors with abnormal bands were plasmacytoma with 1 123 cases, lymphoma with 289 cases, and leukemia with 49 cases. The detection rate of abnormal bands in electropherograms of plasmacytoma was 89.92% (1 123/1 249), which was higher than that in lymphoma and leukemia [6.73% (289/4 296) and 6.40% (49/766), respectively, P<0.01]. Among 4 240 patients with positive M protein, the proportion of 51-60, 61-70 and 71-80 years old patients were 20.33% (862/4 240), 34.32% (1 455/4 240) and 21.32% (904/4 240), respectively, and the differences among age groups were statistically significant ( P<0.01). The results of M protein types showed that the proportion of IgG-κ type was the highest in both genders, with 32.28% (902/2 794) in males and 34.30% (496/1 446) in females. In the 21-30, 31-40, and 41-50 age groups, the proportion of IgG-λ was the highest, which were 38.89% (7/18), 36.26% (33/91) and 34.07% (124/364) in these groups respectively. However, the proportions of IgG-κ were the highest in either of the 51-60, 61-70, 71-80, 81-90 and ≥91 years old groups, which were 33.87% (292/862), 34.16% (497/1 455), 31.53% (285/904), 34.57% (168/486), 28.33% (17/60), respectively, and the differences among all age groups and gender groups had statistical significance ( P<0.01). Among patients with positive M protein in the tumor group, plasmacytoma accounted for 14.22% (603/4 240), followed by lymphoma 6.30% (267/4 240); among non-tumor diseases, M proteinemia accounted for the highest proportion (7.24%, 307/4 240), followed by pulmonary infection (5.47%, 232/4 240). Conclusions:The detection rate of abnormal bands in capillary zone electrophoresis may increase with age, and is higher in males than in females in the same age group; different malignant tumor diseases can also show abnormal bands in capillary zone electrophoresis, but they are still mainly hematological tumors. Among the positive results of M protein, 61-70 years old group accounts for the highest proportion; the most common type of monoclonal gammopathy is IgG type; in the age group of 21-50 years, the proportion of IgG-λ type is the highest; in the group of >50 years old, the proportion of IgG-κ type is the highest; in the diagnosis of positive monoclonal gammopathy, the top 3 diseases are all hematological diseases, including plasmacytoma, monoclonal gammopathies and lymphoma.

Objective To observe the effect of multi-modal hand hygiene(HH)intervention on HH compliance,as well as the relationship between HH compliance and the healthcare-associated(HA)case infection incidence.Methods From 2014 to 2022,the infection control team in a tertiary first-class hospital implemented multi-modal HH intervention for health care workers(HCWs).The changing trend of HH monitoring data,the correlation be-tween HH compliance rate and HA case infection incidence were analyzed retrospectively.Results The consump-tion of HH products in the wards showed a stable upward trend;HH compliance rate increased from 64.98％in 2014 to 85.01％in 2022(P＜0.001),and HA case infection incidence decreased from 1.21％to 0.83％(P＜0.05).HH compliance rate was negatively correlated with HA case infection incidence(r=-0.369,P=0.027).HH compliance rates in different regions and job posts in each quarter were increased(P＜0.001).For 5 different HH moments in each quarter,HH compliance rate fluctuated slightly before sterile manipulation and after touching patient;presented rising trend after touching surroundings around patient,and decreased before touching patient and after touching patient's body fluid since 2020(P＜0.001).Conclusion Multi-modal HH intervention can im-prove the HH compliance of HCWs,improving their HH awareness is conducive to reducing HA case infection incidence.

Objective:To summarize the best evidence for the management of ovarian hyperstimulation syndrome in patients undergoing assisted reproductive therapy.Methods:Evidence related to the management of ovarian hyperstimulation syndrome in patients undergoing assisted reproductive therapy,including guidelines,clinical decision,best clinical practice,systematic evaluation,expert consensus and evidence summary and related original research were systematically searched in UpToDate,BMJ Best Practice,World Health Organization(WHO)website,Guidelines International Network(GIN),National Institute for Health and Clinical Excellence(NICE)website,National Guidelines website,American Society for Reproductive Medicine(ASRM)website,New York Academy of Sciences(NYAS)website,Joanna Briggs Institute(JBI)database,Cochrane Library,CINAHL,PubMed,Wanfang database,CNKI,and China Biomedical Literature Database from inception to May 31,2024.Two researchers independently evaluated the quality of the literature,and a senior researcher made the final decision for literature inclusion.Results:A total of 15 articles were included in the study.Following quality assessment,one article was excluded.The remaining 14 articles included 5 practice guidelines,3 systematic reviews,2 expert consensuses,1 evidence summary,and 3 from UpToDate.Ultimately,27 pieces of evidence were identified across five key aspects:risk assessment,disease monitoring,early prevention,institutional management and health education.Conclusion:The updated evidence indicates that the monitoring and prevention of ovarian hyperstimulation syndrome should start early,personalized treatment plans should be provided for patients,and the rational allocation of treatment resources needs to be promoted to enhance effective management of ovarian hyper-stimulation syndrome.

Objective To observe the value of feature pyramid network(FPN)for automatic segmentation and semantic feature classification of spontaneous intracerebral hemorrhage(sICH)hematoma showed on non-contrast CT.Methods Non-contrast CT images of 408 sICH patients in hospital A(training set)and 103 sICH patients in hospital B(validation set)were retrospectively analyzed.Deep learning(DL)segmentation model was constructed based on FPN to segment the hematoma region,and its efficacy was assessed using intersection over union(IoU),Dice similarity coefficient(DSC)and accuracy.Then DL classification model was established to identify the semantic features of sICH hematoma.Receiver operating characteristic curves were drawn,and the area under the curves(AUC)were calculated to evaluate the efficacy of DL classification model for recognizing semantic features of sICH hematoma.Results The IoU,DSC and accuracy of DL segmentation model for 95％sICH hematoma in training set was 0.84±0.07,0.91±0.04 and(88.78±8.04)％,respectively,which was 0.83±0.07,0.91±0.05 and(88.59±7.76)％in validation set,respectively.The AUC of DL classification model for recognizing irregular shape,uneven density,satellite sign,mixed sign and vortex sign of sICH hematoma were 0.946-0.993 and 0.714-0.833 in training set and validation set,respectively.Conclusions FPN could accurately,effectively and automatically segment hematoma of sICH,hence having high efficacy for identifying semantic features of sICH hematoma.
