ObjectiveTo investigate the association between albumin （Alb） and recompensation by comparing recompensation rate between hepatitis B/C virus-related decompensated liver cirrhosis patients with different Alb levels， and to provide guidance for the identification and management of high-risk patients in clinical practice. MethodsRelated clinical data were collected from 734 patients with hepatitis B/C virus-related decompensated liver cirrhosis who attended The Third People’s Hospital of Kunming from January 1， 2016 to December 31， 2022， and they were divided into three groups based on the level of Alb. The linear regression analysis and chi-square test were used for trend tests. The Kaplan-Meier curve was plotted for the cumulative incidence rate of recompensation in the three groups， and the log-rank test was used for comparison between groups. A Cox proportional-hazards regression model analysis was used to investigate the association between Alb and recompensation in patients with hepatitis B/C virus-related decompensated liver cirrhosis. ResultsAmong the 734 patients with hepatitis B/C virus-related decompensated liver cirrhosis， 270 achieved recompensation， with a recompensation rate of 36.8%. All patients had a median Alb level of 29.90 （25.90 — 34.80） g/L on admission， and according to the level of Alb， they were divided into <25.9 g/L group with 177 patients， 25.9 — 34.8 g/L group with 377 patients， and >34.8 g/L group with 180 patients； 36 patients （20.3%） in the <25.9 g/L group， 138 （36.6%） in the 25.9 — 34.8 g/L group， and 96 （53.3%） in the >34.8 g/L group achieved recompensation， and the recompensation rate increased with the increase in Alb level （χ²=41.730， P<0.001）. After adjustment for all confounding factors， compared with the <25.9 g/L group， there was a significant increase in the incidence rate of recompensation in the 25.9 — 34.8 g/L group （hazard ratio ［HR］=1.842， 95% confidence interval ［CI］： 1.274 — 2.663） and the >34.8 g/L group （HR=2.336， 95% CI： 1.575 — 3.463）. The Kaplan-Meier survival analysis showed that there was a significant difference in the cumulative incidence rate of recompensation between the three groups （χ²=41.632， P<0.001）. ConclusionAlb level is an influencing factor for recompensation in patients with hepatitis B/C virus-related decompensated liver cirrhosis， and the recompensation rate increases with the increase in Alb level.

Objective:To observe the changes in choroidal morphology and blood perfusion in patients with macular edema secondary to retinal vein occlusion (RVO) after intravitreal injections of ranibizumab.Methods:A cohort study was performed.A total of 157 patients (157 eyes) with macular edema secondary to monocular acute retinal vein occlusion (RVO) were enrolled in the Third People's Hospital of Dalian from January 2022 to March 2023.There were 66 cases (66 eyes) with central retinal vein occlusion (CRVO) and 91 cases (91 eyes) with branch retinal vein occlusion (BRVO).All patients were treated with 3+ pro re nata (PRN) regimen of ranibizumab.Before and 1 month after each injection, the central retinal thickness of the macula was measured by optical coherence tomography (OCT).Clear images of the choroid were obtained using the OCT enhanced depth scan mode.Subfoveal choroidal thickness (SFCT), the nasal choroidal thickness at 1 500 μm of macula (CT N1.5 mm), the temporal choroidal thickness at 1 500 μm of macula (CT T1.5 mm) were measured and mean macular thickness (CT Mean) was calculated.Binarization of choroidal images processed by ImageJ software was used to analyze luminal area (LA), stromal area (SA) and total choroidal area (TCA), and choroidal vascularity index (CVI) was calculated.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of the Third People's Hospital of Dalian (No.2023-145-001).Results:SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, LA, SA, TCA and CVI of RVO eyes were higher than those of the contralateral eyes and the differences were statistically significant (all P<0.01).CT Mean in CRVO group was (326.99±64.92)μm, which was higher than (299.80±73.08)μm in BRVO group, with a statistically significant difference ( t=2.41, P=0.02).Baseline CVI values in CRVO group and BRVO group were (72.50±5.62)% and (72.33±5.85)%, respectively, with no significant difference ( t=0.187, P=0.85).In eyes with RVO, CRVO and BRVO, SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, LA, SA, TCA and CVI after every injection were lower than the baseline and the differences were statistically significant (all P<0.05).In eyes with CRVO, there was no significant difference in LA and CVI between first and second injections (both P>0.05), and SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, SA and TCA after second injection were lower than those after first injection with statistically significant differences (all P<0.05).In eyes with BRVO, there was no significant difference in SA and CVI between first and second injections (both P>0.05), and SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, LA and TCA after second injection were lower than those after first injection with statistically significant differences (all P<0.05).In eyes with RVO, CRVO and BRVO, there was no significant difference in SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, SA, TCA and CVI between second and third injections (all P>0.05). Conclusions:After intravitreal injection of ranibizumab, the choroidal thickness becomes thinner and CVI decreases in eyes with macular edema secondary to RVO, and remain relatively stable after the second injection.

Objective:To evaluate the efficacy of remimazolam-based anesthesia in daytime laparoscopic cholecystectomy.Methods:In this multicenter, non-inferiority, randomized controlled trial, 300 American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients of either sex, aged 18-60 yr, with body mass index of 18-28 kg/m 2, who underwent daytime laparoscopic cholecystectomy under general anesthesia with tracheal intubation at Sir Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine, the Fourth Affiliated Hospital of Zhejiang University School of Medicine, Jinhua Hospital Affiliated to Zhejiang University School of Medicine, Hangzhou First People′s Hospital Affiliated to Westlake University School of Medicine, Ningbo No. 2 Hospital, and the Second Affiliated Hospital of Nanchang University from August 2021 to August 2023, were selected and divided into 2 groups ( n=150 each) using a random number table method: remimazolam group (R group) and propofol group (P group). Anesthesia was induced as follows: Sufentanil was intravenously injected at a rate of 0.5 μg/kg, remimazolam was intravenously injected at a rate of 0.3 mg/kg in group R, propofol was intravenously injected at a rate of 2.0-2.5 mg/kg in group P, and cisatracurium besilate was intravenously injected at a rate of 0.2 mg/kg after loss of consciousness in two groups. The patients were mechanically ventilated after tracheal intubation. Anesthesia was maintained as follows: Remimazolam was intravenously injected at a rate of 0.5-1.0 mg·kg -1·h -1 in group R, propofol was intravenously injected at a rate of 4-10 mg·kg -1·h -1 in group P, and remifentanil was intravenously infused at a rate of 0.25-2.00 μg·kg -1·min -1, maintaining intraoperative bispectral index value of 40-60. The success rate of sedation was recorded, and non-inferiority tests were conducted. The time to loss of consciousness, emergence time, extubation time, recovery time of orientation, time of stay in post-anesthesia care unit and occurrence of delayed emergence were recorded. Liver function and renal function were measured before operation and within 24 h after operation. The occurrence of abnormal alanine transaminase, abnormal aspartate transaminase, abnormal creatinine and abnormal urea was recorded. The occurrence of adverse reactions during and after operation was recorded. Results:The success rates of sedation were 98.6% and 99.3% in group R and group P, respectively, there was no statistically significant difference in the success rate of sedation between the two groups ( P>0.05), and the difference in the success rates of sedation between the two groups was -0.007 (95% confidence interval-0.0301-0.0161), which met the pre-set non-inferiority criteria(95% confidence interval >-0.055). Compared with group P, the time to loss of consciousness and recovery time of orientation were significantly prolonged, and the incidence of delayed emergence was increased ( P<0.05), and no statistically significant changes were found in the emergence time, extubation time, time of stay in post-anesthesia care unit and severity of postoperative nausea and vomiting in group R ( P>0.05). There was no statistically significant difference in the abnormal rates of alanine transaminase, aspartate transaminase, creatinine and urea before and after operation between the two groups ( P>0.05). Conclusions:The efficacy of remimazolam-based anesthesia in daytime laparoscopic cholecystectomy is not inferior to that of propofol-based anesthesia.

Background and purpose:Diffuse large B-cell lymphoma(DLBCL)is subclassified into germinal center B-cell-like(GCB)and non-GCB subtypes,which differ in prognosis and treatment response.However,current distinction still relies on invasive pathological assays.This study developed radiomics and deep-learning models based on multiparametric magnetic resonance imaging(MRI)to non-invasively differentiate the two subtypes preoperatively,thereby reducing dependence on histopathological examination.Methods:This study retrospectively included patients with pathologically confirmed DLBCL diagnosed at Huashan Hospital,Fudan University,and other institutions between March 2013 and December 2024.Using multiparametric MRI data,we developed DLBCL-subtype classification models that combined 4 radiomics-based machine-learning algorithms:support vector machine(SVM),logistic regression(LR),Gaussian process(GP)and Naive Bayes(NB),with 3 deep-learning architectures[densely-connected convolutional networks 121(DenseNet121),residual network 101(ResNet101)and EfficientNet-b5].Additionally,two radiologists with different experience levels independently classified DLBCL on MRI in a blinded fashion.Model and radiologist performance were quantified using the area under the receiver operating characteristic curve(AUC),accuracy(ACC),and F1-score to evaluate their ability to distinguish GCB from non-GCB subtypes.This study was approved by the Ethics Committee of Huashan Hospital of Fudan University(No.KY2024-663),and all patients signed informed consents.Results:A total of 173 patients were enrolled(55 with GCB subtype and 118 with non-GCB subtype).Radiomics and deep learning methods effectively distinguished DLBCL subtypes.Among these,the GP radiomics model(based on T1-CE+T2-FLAIR+ADC sequences)and DenseNet121 deep learning model(based on T1-CE+T2-FLAIR+ADC sequences)demonstrated optimal performance.Both achieved excellent results on the internal validation set(GP:AUC=0.900,ACC=0.896,F1=0.840;DenseNet121:AUC=0.846,ACC=0.854,F1=0.774)and maintained robustness on the external validation set.Furthermore,the classification efficacy of the optimal AI model surpassed that of experienced radiologists(highest physician AUC=0.678).Conclusion:Radiomics and deep-learning models based on multiparametric MRI features can effectively differentiate GCB from non-GCB subtypes of DLBCL.Among them,GP and DenseNet121 exhibit outstanding performance,especially when integrating multi-sequence feature sets for classifying DLBCL subtypes on complex imaging data.

Objective:To observe the changes in choroidal morphology and blood perfusion in patients with macular edema secondary to retinal vein occlusion (RVO) after intravitreal injections of ranibizumab.Methods:A cohort study was performed.A total of 157 patients (157 eyes) with macular edema secondary to monocular acute retinal vein occlusion (RVO) were enrolled in the Third People's Hospital of Dalian from January 2022 to March 2023.There were 66 cases (66 eyes) with central retinal vein occlusion (CRVO) and 91 cases (91 eyes) with branch retinal vein occlusion (BRVO).All patients were treated with 3+ pro re nata (PRN) regimen of ranibizumab.Before and 1 month after each injection, the central retinal thickness of the macula was measured by optical coherence tomography (OCT).Clear images of the choroid were obtained using the OCT enhanced depth scan mode.Subfoveal choroidal thickness (SFCT), the nasal choroidal thickness at 1 500 μm of macula (CT N1.5 mm), the temporal choroidal thickness at 1 500 μm of macula (CT T1.5 mm) were measured and mean macular thickness (CT Mean) was calculated.Binarization of choroidal images processed by ImageJ software was used to analyze luminal area (LA), stromal area (SA) and total choroidal area (TCA), and choroidal vascularity index (CVI) was calculated.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of the Third People's Hospital of Dalian (No.2023-145-001).Results:SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, LA, SA, TCA and CVI of RVO eyes were higher than those of the contralateral eyes and the differences were statistically significant (all P<0.01).CT Mean in CRVO group was (326.99±64.92)μm, which was higher than (299.80±73.08)μm in BRVO group, with a statistically significant difference ( t=2.41, P=0.02).Baseline CVI values in CRVO group and BRVO group were (72.50±5.62)% and (72.33±5.85)%, respectively, with no significant difference ( t=0.187, P=0.85).In eyes with RVO, CRVO and BRVO, SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, LA, SA, TCA and CVI after every injection were lower than the baseline and the differences were statistically significant (all P<0.05).In eyes with CRVO, there was no significant difference in LA and CVI between first and second injections (both P>0.05), and SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, SA and TCA after second injection were lower than those after first injection with statistically significant differences (all P<0.05).In eyes with BRVO, there was no significant difference in SA and CVI between first and second injections (both P>0.05), and SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, LA and TCA after second injection were lower than those after first injection with statistically significant differences (all P<0.05).In eyes with RVO, CRVO and BRVO, there was no significant difference in SFCT, CT T1.5 mm, CT N1.5 mm, CT Mean, SA, TCA and CVI between second and third injections (all P>0.05). Conclusions:After intravitreal injection of ranibizumab, the choroidal thickness becomes thinner and CVI decreases in eyes with macular edema secondary to RVO, and remain relatively stable after the second injection.

ObjectiveTo investigate the influencing factors for recompensation in patients with decompensated hepatitis C cirrhosis， and to establish a predictive model. MethodsA total of 217 patients who were diagnosed with decompensated hepatitis C cirrhosis and were admitted to The Third People’s Hospital of Kunming l from January， 2019 to December， 2022 were enrolled， among whom 63 patients who were readmitted within at least 1 year and had no portal hypertension-related complications were enrolled as recompensation group， and 154 patients without recompensation were enrolled as control group. Related clinical data were collected， and univariate and multivariate analyses were performed for the factors that may affect the occurrence of recompensation. The independent-samples t test was used for comparison of normally distributed measurement data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed measurement data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. A binary Logistic regression analysis was used to investigate the influencing factors for recompensation in patients with decompensated hepatitis C cirrhosis， and the receiver operating characteristic （ROC） curve was used to assess the predictive performance of the model. ResultsAmong the 217 patients with decompensated hepatitis C cirrhosis， 63 （29.03%） had recompensation. There were significant differences between the recompensation group and the control group in HIV history （χ²=4.566， P=0.034）， history of partial splenic embolism （χ²=6.687， P=0.014）， Child-Pugh classification （χ²=11.978， P=0.003）， grade of ascites （χ²=14.229， P<0.001）， albumin （t=4.063， P<0.001）， prealbumin （Z=-3.077， P=0.002）， high-density lipoprotein （t=2.854， P=0.011）， high-sensitivity C-reactive protein （Z=-2.447， P=0.014）， prothrombin time （Z=-2.441， P=0.015）， carcinoembryonic antigen （Z=-2.113， P=0.035）， alpha-fetoprotein （AFP） （Z=-2.063， P=0.039）， CA125 （Z=-2.270， P=0.023）， TT3 （Z=-3.304， P<0.001）， TT4 （Z=-2.221， P=0.026）， CD45⁺ （Z=-2.278， P=0.023）， interleukin-5 （Z=-2.845， P=0.004）， tumor necrosis factor-α （Z=-2.176， P=0.030）， and portal vein width （Z=-5.283， P=0.005）. The multivariate analysis showed that history of partial splenic embolism （odds ratio ［OR］=3.064， P=0.049）， HIV history （OR=0.195， P=0.027）， a small amount of ascites （OR=3.390， P=0.017）， AFP （OR=1.003， P=0.004）， and portal vein width （OR=0.600， P<0.001） were independent influencing factors for the occurrence of recompensation in patients with decompensated hepatitis C cirrhosis. The ROC curve analysis showed that HIV history， grade of ascites， history of partial splenic embolism， AFP， portal vein width， and the combined predictive model of these indices had an area under the ROC curve of 0.556， 0.641， 0.560， 0.589， 0.745， and 0.817， respectively. ConclusionFor patients with decompensated hepatitis C cirrhosis， those with a history of partial splenic embolism， a small amount of ascites， and an increase in AFP level are more likely to experience recompensation， while those with a history of HIV and an increase in portal vein width are less likely to experience recompensation.

Cancer incidence in China has been rising steadily,with a particularly heavy burden from several high-prevalence malignancies.Medical examination for cancer plays a critical role in the early detection of cancer,precancerous lesions,and precursor conditions,thereby facilitating timely diagnosis and intervention.Such examination also addresses the growing demand for person-alized cancer screening services among diverse population groups.The development of evidence-based,context-specific cancer screening guidelines is essential to enhance the standardization,quality,and equity of preventive screening practices across the country,ultimately improving out-comes in early cancer detection and treatment.Guided by the Department of Medical Emergency Response of the National Health Commission,the Guidelines for Medical Examination for Cancer in Health Examination Agency(2025 Edition)were developed under the leadership of the National Cancer Center.A multidisciplinary panel of experts formulated the guidelines in accordance with the principles and methodology of the World Health Organization Handbook for Guideline Deve-lopment.The guidelines provide evidence-based recommendations on key clinical domains:target cancers and populations,overall screening workflow,screening protocols,diagnostic technolo-gies,result interpretation,follow-up procedures,and quality control.The primary objective is to standardize cancer screening practices in health examination agency and strengthen China's ca-pacity for prevention and control of high-burden cancers.

Systemic mastocytosis (SM) with an associated myelodysplastic/myeloproliferative neoplasm (MDS/MPN) is a rare subtype of myeloid neoplasms. Avapritinib, a potent and selective inhibitor of KIT D816V, is approved for treating advanced systemic mastocytosis (AdvSM). We report a case of a patient with SM and an associated MDS/MPN treated with avapritinib. The patient achieved sustained complete remission (CR) of SM, with persistent molecular negativity for the KIT D816V mutation, but ultimately succumbed to disease progression to chronic myelomonocytic leukemia (CMML). Although avapritinib, a novel targeted therapy, has significantly improved outcomes for SM, the efficacy of treatment for the associated hematologic neoplasm in patients with SM-AHN may be the primary determinant of long-term overall survival and progression-free survival. This report includes a review of relevant literature to provide insights into the clinical diagnosis and management of this rare entity.

To enhance the understanding of familial erythrocytosis type 2 (ECYT2) resulting from compound heterozygous mutations in the VHL gene.Methods:We conducted a retrospective analysis of the case data from a patient with ECYT2 to investigate its pathogenesis, clinical features, diagnosis and treatment options, as well as prognosis, while also reviewing the relevant literature.Results:A 31-year-old man was admitted to the hospital due to facial and hand flushing that had persisted for 29 years. Whole exome sequencing revealed compound heterozygous mutations in VHL p.P81L and p.N90T. Both of his parents were found to carry only one of these heterozygous mutations, yet they exhibited normal phenotypes. Based on the patient's hematological tests, a clear diagnosis of ECYT2 was established. Following treatment with erythrocytapheresis and daily administration of aspirin at a dosage of 100 mg, the patient experienced relief from dizziness and headaches associated with blood hyperviscosity, without any thrombotic or bleeding complications during this period.Conclusions:ECYT2 is a rare group of autosomal recessive genetic disorders. This case of ECYT2, resulting from compound heterozygous mutations in the VHL gene, represents the first report in China. Clinically, it is characterized by elevated red cell mass, normal or increased serum erythropoietin levels, and normal hemoglobin oxygen affinity levels. These factors contribute to thrombotic and bleeding complications that can lead to early mortality.

Objective:To compare the clinical and laboratory characteristics and survival between Chinese and Western patients with myelodysplastic neoplasms (MDS) .Methods:Clinical and laboratory data were collected from 1,464 primary adult patients diagnosed with MDS at the Institute of Hematology & Blood Diseases Hospital from August 2016 to June 2024. Collected data were retrospectively analyzed and compared with 2,191 patients from the International Working Group for the Prognosis of Myelodysplastic Syndromes (IWG-PM) .Results:Chinese patients were significantly younger (median age: 56 years vs. 72 years, P<0.001) and experienced more severe hematopenia ( P<0.001) compared with patients from the IWG-PM. Further, Chinese patients exhibited a higher percentage of isolated del (20q), +8, and complex karyotypes as well as a lower percentage of normal karyotypes, del (5q), and -Y ( P<0.001). Higher U2AF1, NRAS, and NPM1 mutation rates and lower ASXL1, SF3B1, and RUNX1 mutation rates were observed in Chinese patients than in participants from the IWG-PM ( P<0.05). No significant difference in overall survival (OS) was found between the two groups (median OS: 48 [95% CI: 40 - 56]months, vs. 45[95% CI: 40 - 49] months; P=0.449). Among participants aged ≤45 years, Chinese patients demonstrated more trisomy 8 ( P=0.070) and U2AF1 mutation ( P<0.001) and higher 4-year OS rate compared with those from the IWG-PM (75.5% vs. 62.1%, P=0.001). Among participants aged ≥70 years, Chinese patients exhibited more complex karyotypes but fewer del (5q) as well as more NPM1 but less SF3B1 and TET2 compared with those from the IWG-PM ( P<0.05). Chinese patients demonstrated shorter survival (median OS: 20 [95% CI: 13 - 27] months vs. 37 [95% CI: 32 - 42] months, P<0.001) . Conclusion:Chinese and Western MDS patients differ in age of onset, clinical features, and cytogenetic or molecular genetic abnormalities, with significant differences persisting in age-matched groups. Although the OS is similar, disparities exist in survival for younger and older patients between the two populations.
