Pulmonary microecology is a key role of traditional Chinese medicine in improving pulmonary fibrosis

Idiopathic pulmonary fibrosis(IPF)is a type of interstitial lung disease,characterized by an unknown etiology,chronicity,and progressive respiratory impairment.Following IPF diagnosis,patients exhibit a median survival of only 2 to 3 years,with a staggering 70% to 80% mortality rate within 5 years[1].However,the corresponding therapeutic options remain severely limited.Presently,the efficacious treatment drugs are Pirfenidone and Nintedanib.Regrettably,these two drugs fail to substantially reverse pulmonary fibrosis,offering only a partial slowing of its progression.IPF predominantly afflicts the elderly[1],and with the aging population in China constinuously increasing,there is a compelling need to explore novel and more effective treatment strategies.

Genetic Diversity,Antibiotic Resistance,and Pathogenicity of Aeromonas Species from Food Products in Shanghai,China

Objective Aeromonas has recently been recognized as an emerging human pathogen.Aeromonasassociated diarrhea is a phenomenon occurring worldwide.This study was designed to determine the prevalence,genetic diversity,antibiotic resistance,and pathogenicity of Aeromonas strains isolated from food products in Shanghai.Methods Aeromonas isolates(n=79)collected from food samples were analyzed using concatenated gyrB-cpn60 sequencing.The antibiotic resistance of these isolates was determined using antimicrobial susceptibility testing.Pathogenicity was assessed usingβ-hemolytic,extracellular protease,virulence gene detection,C.elegans liquid toxicity(LT),and cytotoxicity assays.Results Eight different species were identified among the 79 isolates.The most prevalent Aeromonas species were A.veronii[62(78.5%)],A.caviae[6(7.6%)],A.dhakensis[3(3.8%)],and A.salmonicida[3(3.8%)].The Aeromonas isolates were divided into 73 sequence types(STs),of which 65 were novel.The isolates were hemolytic(45.6%)and protease-positive(81.0%).The most prevalent virulence genes were act(73.4%),fla(69.6%),aexT(36.7%),and ascV(30.4%).The results of C.elegans LT and cytotoxicity assays revealed that A.dhakensis and A.hydrophila were more virulent than A.veronii,A.caviae,and A.bivalvium.Antibiotic resistance genes[tetE,blaTEM,tetA,qnrS,aac(6)-Ib,mcr-1,and mcr-3]were detected in the isolates.The multidrug-resistance rate of the Aeromonas isolates was 11.4%,and 93.7%of the Aeromonas isolates were resistant to cefazolin.Conclusion The taxonomy,antibiotic resistance,and pathogenicity of different Aeromonas species varied.The Aeromonas isolates A.dhakensis and A.hydrophila were highly pathogenic,indicating that food-derived Aeromonas isolates are potential risks for public health and food safety.The monitoring of food quality and safety will result in better prevention and treatment strategies to control diarrhea illnesses in China.

Adolescent alcohol exposure changes RNA modifications in adult brain by mass spectrometry-based comprehensive profiling analysis

Alcohol consumption is one of the leading causes of death worldwide.Adolescence is a critical period of structural and functional maturation of the brain.Adolescent alcohol use can alter epigenetic modifications.However,little is known on the long-term effects of alcohol consumption during adolescence on RNA epigenetic modifications in brain.Herein,we systematically explored the long-term effects of alcohol exposure during adolescence on small RNA modifications in adult rat brain tissues by comprehensive liquid chromatography-electrospray ionization-tandem mass spectrometry(LC-ESI-MS/MS)analysis.We totally detected 26 modifications in small RNA of brain tissues.Notably,we observed most of these modifications were decreased in brain tissues.These results suggest that alcohol exposure during adolescence may impose a long-lasting impact on RNA modifications in brain tissues.This is the first report that alcohol use during adolescence can alter RNA modifications in adult brain.Collectively,this study suggests a long-term adverse effects of alcohol consumption on brain from RNA epigenetics angle by comprehensive mass spectrometry analysis.

Global burden and trends of lung cancer incidence and mortality

Background:Lung cancer has been the leading cause of cancer-related deaths worldwide for many years.This study aimed to investigate the global patterns and trends of lung cancer.Methods:Lung cancer incidence and mortality were derived from the GLOBOCAN 2020 database.Continuous data from Cancer Incidence in Five Continents Time Trends were used to analyze the temporal trends from 2000 to 2012 using Joinpoint regression,and average annual percent changes were calculated.The association between the Human Development Index and lung cancer incidence and mortality was assessed by linear regression.Results:An estimated 2.2 million new lung cancer cases and 1.8 million lung cancer-related deaths occurred in 2020.The age-standardized incidence rate(ASIR)ranged from 36.8 per 100,000 in Demark to 5.9 per 100,000 in Mexico.The age-standardized mortality rate(ASMR)varied from 32.8 per 100,000 in Poland to 4.9 per 100,000 in Mexico.Both ASIR and ASMR were approximately twice higher in men than in women.The ASIR of lung cancer showed a downward trend in the United States of America(USA)between 2000 and 2012,and was more prominent in men.The age-specific incidence rates of lung cancer for ages of 50 to 59 years showed an upward trend in China for both men and women.Conclusions:The burden of lung cancer is still unsatisfactory,especially in developing countries like China.Considering the effectiveness of tobacco control and screening in developed countries,such as the USA,there is a need to strengthen health education,accelerate the establishment of tobacco control policies and regulations,and improve early cancer screening awareness to reduce the future burden of lung cancer.

Cellular proteomic profiling of esophageal epithelial cells cultured under physioxia or normoxia reveals high correlation of radiation response

Objective To investigate the radiation response and proteomic profiling of esophageal epithelial cells cultured under physioxia and normoxia.Methods The human immortalized normal esophageal epithelial cell line SHEE cells were cultured under normoxia(21%)and physioxia(4%),respectively.A clonogenic assay was performed to evaluate the radiation response of SHEE cells.Cellular proteomic profiling of SHEE cells maintained under physioxia and normoxia was conducted to determine the differentially expressed proteins.Then,the identified differentially expressed proteins were validated by Western blot.Results SHEE cells exposed to normoxia showed an increased radiation response compared to physioxia(irradiation dose≥10Gy,P<0.05).Over 1200 non-redundant proteins were identified in the collected samples.Protein expression was compared between physioxia and normoxia,42 proteins were downregulated and 45 proteins upregulated,in which oxidative phosphorylation was the most significantly enriched pathway.When cells were cultured under normoxia conditions,the induction of antioxidant genes appeared to contribute to form a phenotype adapted to the environment with high oxygen-content.Further analysis validated NRF2,BIP,VCP,SOD1,and YAP1 were the key regulators of this phenotype.Conclusions Compared with physioxia,normoxic cell culture condition can enhance the radiation response.This study could stimulate in vivo microenvironment,and provide a basis for radiation-induced normal tissue damage.

Accuracy of baseline low-dose computed tomography lung cancer screening: a systematic review and meta-analysis

Background:Screening using low-dose computed tomography(LDCT)is a more effective approach and has the potential to detect lung cancer more accurately.We aimed to conduct a meta-analysis to estimate the accuracy of population-based screening studies primarily assessing baseline LDCT screening for lung cancer.Methods:MEDLINE,Excerpta Medica Database,and Web of Science were searched for articles published up to April 10,2022.According to the inclusion and exclusion criteria,the data of true positives,false-positives,false negatives,and true negatives in the screening test were extracted.Quality Assessment of Diagnostic Accuracy Studies-2 was used to evaluate the quality of the literature.A bivariate random effects model was used to estimate pooled sensitivity and specificity.The area under the curve(AUC)was calculated by using hierarchical summary receiver-operating characteristics analysis.Heterogeneity between studies was measured using the Higgins I 2 statistic,and publication bias was evaluated using a Deeks’funnel plot and linear regression test.Results:A total of 49 studies with 157,762 individuals were identified for the final qualitative synthesis;most of them were from Europe and America(38 studies),ten were from Asia,and one was from Oceania.The recruitment period was 1992 to 2018,and most of the subjects were 40 to 75 years old.The analysis showed that the AUC of lung cancer screening by LDCT was 0.98(95%CI:0.96-0.99),and the overall sensitivity and specificity were 0.97(95%CI:0.94-0.98)and 0.87(95%CI:0.82-0.91),respectively.The funnel plot and test results showed that there was no significant publication bias among the included studies.Conclusions:Baseline LDCT has high sensitivity and specificity as a screening technique for lung cancer.However,long-term follow-up of the whole study population(including those with a negative baseline screening result)should be performed to enhance the accuracy of LDCT screening.

Enhanced optical imaging and fluorescent labeling for visualizing drug molecules within living organisms

The visualization of drugs in living systems has become key techniques in modern therapeutics.Recent advancements in optical imaging technologies and molecular design strategies have revolutionized drug visualization.At the subcellular level,super-resolution microscopy has allowed exploration of the molecular landscape within individual cells and the cellular response to drugs.Moving beyond subcellular imaging,researchers have integrated multiple modes,like optical near-infrared II imaging,to study the complex spatiotemporal interactions between drugs and their surroundings.By combining these visualization approaches,researchers gain supplementary information on physiological parameters,metabolic activity,and tissue composition,leading to a comprehensive understanding of drug behavior.This review focuses on cutting-edge technologies in drug visualization,particularly fluorescence imaging,and the main types of fluorescent molecules used.Additionally,we discuss current challenges and prospects in targeted drug research,emphasizing the importance of multidisciplinary cooperation in advancing drug visualization.With the integration of advanced imaging technology and molecular design,drug visualization has the potential to redefine our understanding of pharmacology,enabling the analysis of drug micro-dynamics in subcellular environments from new perspectives and deepening pharmacological research to the levels of the cell and organelles.

Repair of left ventricular aneurysm： ten-year experience in Chinese patients

Background A large transmural myocardial infarction often results in a dyskinetic or akinetic left ventricular aneurysm （LVA）. This study aimed to explore the early and long-term clinical outcomes and to identify predictors for survivals and hospital re-admission after the repair of left ventricular aneurysm. Methods We followed up 497 patients who had undergone LVA repair from a single center in China between 1995 and 2005. The perioperative parameters were recorded. Risk factors for early mortality and long-term results were analyzed by multivariate Logistic regression. Cox＇s proportional hazard model was used to calculate risk factors for major adverse cardiac and cerebrovascular events, cause of death and re-admission. Kaplan-Meier curve was employed to analyze long-term survival. Results The operative mortality was 2.0%. The long-term mortality was 11.1% and cardiac causes contributed to 61.8% of the overall long-term mortality. Four hundred and thirty-two patients survived during the follow-up period and 37.5% of them had been re-admitted at least one time. One hundred and five patients experienced major adverse cardiac and cerebrovascular events. Survival analysis exhibited that the probability of survival at 1 and 5 years after operation was 96% and 86% respectively. Previous atrial fibrillation was the independent risk factor for early mortality. Independent risk factors for long-term mortality were poor left ventricular ejection fraction and stroke, and risk factors for cardiac mortality were intraventricular block, stroke and poor left ventricular ejection fraction. Stroke, intraventricular block and advanced age were independent risk factors for major adverse cardiac and cerebrovascular events, and New York Heart Association （NYHA） class Ill-IV was the only risk factor for hospital re-admission. Conclusions Postinfarction LVA can be repaired and satisfying early and long-term clinical outcome can be obtained. Endoventricular circular plasty technique is the better choice than linear repair in patients with large LVA. Survival is affected in patients with poor heart function, intraventricular block and stroke.

Role of plasma C-reactive protein and white blood cell count in predicting in-hospital clinical events of acute type A aortic dissection

Background A few recent studies have reported that inflammation is associated with the prognosis of acute aortic dissection （AD）. There is, however, no systemic investigation regarding the role of plasma C-reactive protein （CRP） and white blood cell （WBC） levels in predicting in-hospital clinical events of acute type AAD. Methods The levels of high-sensitivity CRP and WBC counts were systemically determined after admission in 36 patients with acute type A AD. The variations of plasma CRP and WBC levels in different time windows （admission, 1, 2, 3, 4, 6, 8 days） in patients with acute type AAD were analyzed between patients with events and without events. Results During hospitalization, five patients died, and increased levels of CRP and WBC were found in patients died with acute type A AD compared with patients survived （P 〈0.01, respectively）. Medical treatment may significantly decrease inflammatory response in survived patients with acute type A AD. Additionally, patients with complication of pleural effusion showed higher CRP and WBC levers （P=0.046, P=-0.018, respectively）. Lower WBC levels were found in survived patients treated medically （P=-0.001）. Moreover, mean CRP and WBC levels had positive correlations with aortic diameter （r=0.364, P--0.000; r=0.333, P=0.000, respectively） and age （r=0.270, P=0.000, respectively）, while negative correlations with the time from onset of symptoms to hospital admission （r= -0.229, P=0.000, r= -0.200, P=0.002, respectively）. Univariate analysis showed that age 〉65 years, CRP zl 2.05 rag/L, WBC 〉12.16×10^9/L, aortic diameter 〉48 mm, pleural effusion and diastolic blood pressure 〉105 mmHg were associated with hospital mortality. While CRP 〉12.05 mg/L, WBC ≥12.16×10^9/L, aortic diameter 〉48 mm were strongly associated with hospital mortality in multiple Logistic regression analysis. Conclusions The results suggested that CRP and WBC were preferred markers for predicting the clinical events in patients with acute type A AD, especially death during hospitalization. Therefore, further study enrolling larger cohort, prospective study would be warranted.

Therapeutic targets and biomarkers of tumor immunotherapy:response versus non-response

Cancers are highly complex diseases that are characterized by not only the overgrowth of malignant cells but also an altered immune response.The inhibition and reprogramming of the immune system play critical roles in tumor initiation and progression.Immunotherapy aims to reactivate antitumor immune cells and overcome the immune escape mechanisms of tumors.Represented by immune checkpoint blockade and adoptive cell transfer,tumor immunotherapy has seen tremendous success in the clinic,with the capability to induce long-term regression of some tumors that are refractory to all other treatments.Among them,immune checkpoint blocking therapy,represented by PD-1/PD-L1 inhibitors(nivolumab)and CTLA-4 inhibitors(ipilimumab),has shown encouraging therapeutic effects in the treatment of various malignant tumors,such as non-small cell lung cancer(NSCLC)and melanoma.In addition,with the advent of CAR-T,CAR-M and other novel immunotherapy methods,immunotherapy has entered a new era.At present,evidence indicates that the combination of multiple immunotherapy methods may be one way to improve the therapeutic effect.However,the overall clinical response rate of tumor immunotherapy still needs improvement,which warrants the development of novel therapeutic designs as well as the discovery of biomarkers that can guide the prescription of these agents.Learning from the past success and failure of both clinical and basic research is critical for the rational design of studies in the future.In this article,we describe the efforts to manipulate the immune system against cancer and discuss different targets and cell types that can be exploited to promote the antitumor immune response.

Reticulocyte hemoglobin content in the diagnosis of iron deficiency in Chinese pre-menopausal women

Pre-menopausal women are at risk for iron deficiency due to menstrual blood losses. The prevalence rates （PR） of iron depletion, iron deficiency anemia （IDA）, and iron deficiency were 34.4%, 15.1% and 49.5% in pre-menopausal non-pregnant women respectively in China.1 Traditionally, the diagnosis of iron deficiency relies on the hematological markers （hemoglobin （HGB）, mean corpuscular volume （MCV）, mean corpuscular hemoglobin （MCH）, red cell distribution width （RDW）） and biochemical markers （serum ferritin （SF）, serum iron （SI）, transferrin saturation （TS）, total iron-binding capacity （TIBC））. Recently, the reticulocyte hemoglobin content （CHr） is considered to be used as a marker of iron deficiency.2 The aim of this study was to compare the diagnostic efficiency of CHr with the old markers in diagnosis of iron deficiency in Chinese pre-menopausal women.

Ex utero Intrapartum Treatment for the Pericardial Effusion Drain of a Fetal Cardiac Tumor

INTRODUCTION The incidence of fetal cardiac tumor was about 0.14% as determined by fetal echocardiography. It was extremely difficult to deal with the fetus when the severe circulatory instability was induced by a cardiac tumor in the womb. It was reported that ex utero intrapartum treatment （EXIT） procedure solved the problems of fetal airway or pulmonary lesion during delivery to avoid hypoxia after birth. The goal of EXIT is to maintain placental circulation while steps are taken to optimize the transition of the baby from fetal to neonatal life. This study introduced the experience of EXIT procedure to solve the problems of fetal circulation induced by a fetal cardiac tumor.

Nosocomial spread of hospital-adapted CC17 vancomycin-resistant Enterococcus faecium in a tertiary-care hospital of Beijing, China

Background The incidence of vancomycin-resistant enterococci （VRE） appeared to be increasing in China, but very few nosocomial outbreaks have been reported. Our hospital had experienced an outbreak of VRE since March 2008 to March 2009. The objective of this study was to analyze the molecular features of the isolates and the control measures used to eradicate a VRE outbreak in a tertiary institution in China.Methods We characterized VRE isolates from 21 infected and 11 colonized inpatients from a single hospital by pulsed field gel electrophoresis （PFGE）, multilocus sequence typing （MLST）, the analysis of Tn 1546-like elements and virulence genes detection. Infection control measures, including more environmental disinfection, screening for VRE colonization,contact precautions, education and strict antibiotic restriction, were implemented to control the outbreak.Results During the outbreak, a total of 32 VRE strains were obtained. There were 21 strains found in Emergency Intensive Care Unit （EICU）, 9 isolates from Geriatric Ward, and two from other units. All the isolates harbored the vanA gene, however,four of them exhibited the VanB phenotype. Meanwhile, MLST analysis revealed that all isolates belonged to clonal complex （CC） 17. With the infection-control measures, the epidemic was constrained in two units （EICU and Geriatric Ward）. After March 2009, no further case infected with VRE was detected in the following one-year period.Conclusion The outbreak was controlled by continuous implementation of the infection control programme, and more rigorous infection control policy is needed.

The five major autoimmune diseases increase the risk of cancer:epidemiological data froma large-scale cohort study in China

Background:Cancer incidence and mortality have received critical attention during the long-term management of morbidities in patients with autoimmune diseases(AIDs).This study aimed to investigate and compare the risk of cancer associated with five major AIDs in a large-scale Chinese cohort.Methods:A total of 8,120 AID patients consecutively admitted to a national tertiary referral center in China were included and followed-up for 38,726.55 patient-years,including those with systemic lupus erythematosus(SLE),rheumatoid arthritis(RA),Sjoren’s syndrome(SS),systemic scleroderma(SSc),and idiopathic inflammatory myositis(IIM).Demographic data,cancer incidence,predilecting sites and cancer onset time were recorded and compared among the five AIDs.Results:Four hundred and thirty(5.3%)patients developed cancer.Their median agewas 57.5 years and AID durationwas 79.8 months.The estimated total standardized incidence ratio(SIR)of cancer in AIDs patients was 3.37,with the highest SIR observed in IIM(4.31),followed by RA(3.99),SSc(3.77),SS(2.88)and SLE(2.58).The increased SIR of cancers in AID patients showed a female predominance(female vs.male:3.59 vs.2.77)and younger patient involvement(age<50 vs.≥50 years:4.88 vs.3.04).Patientswith SLE had increased SIRs for developing hematologic malignancies and solid tumors located in the urinary bladder,corpus uteri and cervix uteri.Patients with SS had a significantly high SIR for developing non-Hodgkin’s lymphoma.Within 3 years of IIM diagnosis,74.6%of the patients developed cancer and they had a high risk of ovarian cancer.RA was associated with a wide distribution of scancers,including non-Hodgkin’s lymphoma,gynecologic,urinary tract,thyroid gland and lung cancers.SSc patients had increased SIRs for developing cervical uterine,lung,and breast cancers.Conclusion:Patients with five major AIDs in China had an increased risk of developing cancer,with a predominance in women and younger patients,although cancer incidence,predilection sites and cancer onset time may vary greatly in each AID entity.

50th anniversary of artemisinin:From the discovery to allele-aware genome assembly of Artemisia annua

Over the past half century,the fight against malaria has been a resounding success mainlydue to thediscoveryof artemisinin.According to the World Health Organization(WHO),morbidity and mortality due to malaria have been cut by half since the promotion of artemisinin-based combination therapy(WHO,2020).

Prediction of Enhancement Effect of Nitroimidazoles on Irradiation by Gene Expression Programming

A novel machine learning method, gene expression programming（GEP）, was employed to build quatitative structure-activity relationship（QSAR） models for predicting the enhancement effect of nitroimidazole compounds on irradiation. The models were based on descriptors which were calculated from the molecular structures. Four descriptors were selected from the pool of descriptors by best multiple linear regression（BMLR） method. After that, three regression methods, multiple linear regression（MLR）, support vector machine（SVM） and GEP, were used to build QSAR models. Compared to MLR and SVM, GEP produced a better model with the square of correlation coefficient（R2）, 0.9203 and 0.9014, and the root mean square error（RMSE）, 0.6187 and 0.6875, for training set and test set, respectively. The results show that the GEP model has better predictive ability and more reliable than the MLR and SVM models. This indicates that GEP is a promising method on relevant researches in radiation area.

Aortic implantation for anomalous origin of the left coronary artery from the pulmonary artery:A ten-year single center experience

Background At present, creation of a dual coronary system with direct aortic implantation is the preferred management for anomalous origin of left coronary artery from the pulmonary artery （ALCAPA）. However, controversy still exists over the initial management of mitral regurgitation （MR） at the time of ALCAPA repair. Methods Between March 2005 and March 2015, 52 consecutive patients （20 males and 32 females） underwent direct aortic implantation of ALCAPA. Median age at surgery was 10 months （range, 2 to 193）. Mean weight was 9.7_＋7.8 kg. In order to facilitate the analysis, description of MR was given a numeric grade： 0 = none, 1 = trivial, 2 = mild, 2.5 = mild-moderate, 3 = moderate, 3.5 = moderate-severe, and 4 = severe. Results The LV shortening fraction （LVFS） demonstrated significant improvement between presentation and discharge （32.1±10.1% vs. 28.6±9.6%, P = 0.023）, and there was also significant improvement in the mean MR grade between presentation and discharge （2.40＋1.16 vs. 2.91＋ 1.19, P = 0.001）. There were 4 hospital deaths （7.7%）. The median follow-up was 21 months （range 1.5 to 111）, 3 patients （5.8%） were lost to follow-up, 1 patient required reoperation for mitral valve replacement. Significant improvement was seen in LVFS between discharge and late follow-up （38.0±6.0% vs. 32.1±10.1%, P = 0.001）, however, the degree of MR did not dem- onstrate further change （2.29_＋1.20 vs. 2.40＋1.16, P = 0.541）. Conclusion Creation of a dual coronary system with direct aortic implantation of the left coronary artery results in complete recovery of left ventricular function. Concomitant mitral valve （MV） repair for ALCAPA patients with moderate-severe and severe MR is helpful to early MV function recovery.

Nanoparticles targeting at methylases with high correlation to N^(6)-methyladenosine-related lncRNA signatures as potential therapy of kidney clear cell carcinoma

Clear cell renal cell carcinoma(ccRCC)is a heterogeneous malignancy with poor prognosis.Methylation of the N^(6) position of adenosine(m^(6)A),the most common epigenetic modification in both messenger RNAs and noncoding RNAs,has been reported to regulate the initiation and progression of ccRCC.However,whether and how m^(6)A-related long noncoding RNAs(m^(6)ArlncRNAs)signify the progression of ccRCC remain unclear.We found m^(6)ArlncRNAs are effective signatures illustrating immune landscape and risk stratification in ccRCC.We identified two differently expressed m^(6)ArlncRNAs(DEm^(6)ArlncRNAs),AC008870.2 and EMX2OS,as independent risk factors for overall survival of ccRCC patients,by applying stringent variable selection procedure to data from the Cancer Genome Atlas Kidney Renal Clear Cell Carcinoma project.The risk score generated from the DEm^(6)ArlncRNA expression categorizes patients into either high or low-risk groups,between which,enrichment analysis indicated an enrichment in immune-related pathways.Under different DEm^(6)ArlncRNA transcription pattern,the two risk groups differ in immune cell population composition and expression levels of therapy targeting genes.Nanoparticle is satisfactory strategy to delivering therapeutic drugs.For further clinical translation,we designed a novel nanoparticle delivery system packaged STM2457(STM@8P4 NPs),which selectively inhibits AC008870.2-correlated m^(6)A writer.STM@8P4 NPs loaded drug successfully with uniform particle size,long-term stability and high release efficiency.STM@8P4 NPs can easily enter ccRCC cells and showed a highly efficient ccRCC killing activity in vitro.Our results therefore indicate that m^(6)ArlncRNAs expression can depict tumor microenvironment,predict prognosis for ccRCC patient and give hint to therapeutic strategies in ccRCC.

A case of endometrial complex hyperplasia and uterus prolapsed pelvic organ prolapse quantification system stage Ill of a 24-year-old woman with systemic lupus erythematosus

To the editor： The endometrial lesion and uterus prolapsed of young woman presents a distinct feature in uterus prolapsed ofsystemic lupus erythematosus （SLE） patients, but it is receiving little consideration. To our knowledge, there are few reported cases of women with endometrial lesion and SLE. We here reported a case of endometrial complex hyperplasia and uterus prolapsed pelvic organ prolapse quantification system （POP-Q） stage III of a 24-year-old woman with SLE.
