Objective To compare the clinical outcomes and retinal volume changes in patients with ischemic and non-ischemic macular edema secondary to branch retinal vein occlusion(BRVO-ME)using optical coherence tomography angiography(OCTA).Methods The clinical data of 34 ischemic BRVO-ME patients(34 eyes,ischemic group)and 21 non-ischemic BRVO-ME patients(21 eyes,non-ischemic group)were retrospectively analyzed.Patients in both groups re-ceived intravitreal injections of ranibizumab.The best corrected visual acuity(BCVA)and retinal volume of the macular ar-ea were assessed before,1 day,1 week,1 month,3 months and 6 months after the treatment.Results The BCVA(log-MAR)at 1 day after the treatment was 0.63±0.37 in the ischemic group and 0.44±0.22 in the non-ischemic group,and the difference was statistically significant(P=0.017).The retinal volumes of the outer retina,the full retina,and the Farafovea and Perifovea subdivisions of the full retina before the treatment were(6.42±1.90)mm3,(8.75±1.82)mm3,(3.20±0.87)mm3 and(5.10±0.89)mm3 in the ischemic group and(5.52±1.57)mm3,(7.83±1.56)mm3,(2.80± 0.71)mm3,and(4.66±0.77)mm3 in the non-ischemic group,respectively;1 day after treatment,they were(4.97± 1.18)mm3,(7.46±1.47)mm3,(2.62±0.60)mm3 and(4.53±0.80)mm3 in the ischemic group and(4.25±0.48)mm3,(6.58±0.56)mm3,(2.26±0.26)mm3 and(4.06±0.40)mm3 in the non-ischemic group,respectively;at 1 week after the treatment,they were(4.40±0.82)mm3,(6.90±0.85)mm3,(2.38±0.36)mm3 and(4.24±0.49)mm3 in the ischemic group and(4.04±0.35)mm3,(6.33±0.49)mm3,(2.15±0.19)mm3 and(3.95±0.35)mm3 in the non-ische-mic group,respectively,and the differences between the two groups were statistically significant(all P＜0.05).The a-mount of retinal volume change from baseline in the outer retina and the full retina was(-2.48±2.38)mm3 and(-2.54±2.38)mm3 in the ischemic group,and(-1.31±1.58)mm3 and(-1.38±1.58)mm3 in the non-ischemic group at 1 month after treatment,respectively,and the differences between the two groups were statistically significant(both P＜0.05).Conclusion Ranibizumab is effective in treating both ischemic and non-ischemic BRVO-ME.The short-term visu-al prognosis is better in the non-ischemic group than the ischemic group,and the retinal volume is higher in the ischemic group than the non-ischemic group.However,no significant difference is observed in the visual prognosis or retinal volume between the two groups after long-term treatment.

The Asian expert working group completed the 2022 consensus on vernal keratitis (VKC), which provides detailed information on the definition, classification, clinical manifestation, diagnosis and treatment of VKC in Asia and identifies unmet treatment needs, including: (1) lack of clear criteria for the diagnosis and treatment of patients with VKC.The pathogenesis of the disease is unclear, and anti-allergy therapy is often ineffective in patients with moderate or severe VKC; (2) the need for standardized treatment and management strategies.Treatment and management of patients with the same severity varies widely among Asian countries, with a lack of clear, standardized guidelines and grading systems; (3) safety and iatrogenic complications; (4) optimal dosing regimen for pharmacologic treatment.In this article, the aspects mentioned above were interpreted and analyzed in the context of the Expert Consensus on the Diagnosis and Treatment of Allergic Conjunctivitis in China ( 2018), with a view to helping the prevention and treatment of VKC in China.

Objective To explore the role of an artificial intelligence(AI)model based on real-time object detection network in fetal facial ultrasound examination.Methods With the normal fetal facial ultrasound standard plane(FFUSP)at 20-24 weeks of gestation as the research object,a FFUSP recognition model based on real-time object detection network was constructed.The recognition accuracy of the model for FFUSP and the anatomical structures were analyzed,and the clinical value was evaluated by analyzing its performance in identifying FFUSP in 119 cases of fetal ultrasound images.Results The overall precision,recall rate,mAP@.5 and mAP@.5:.95 of the AI model were 97.8%,98.5%,98.1%and 61.0%,respectively.The clinical validation showed that the AI model had a sensitivity,specificity,positive predictive value,negative predictive value and accuracy of 100.0%,98.5%,87.4%,100.0%and 98.7%for facial anatomy recognition,and the results were highly consistent with the classification of fetal ultrasound experts(k=0.925,P<0.001).The recognition accuracy of the model for 3 types of standard planes reached 100%;and the average speed of dynamic video detection was 33.93 frames per second.Conclusion The FFUSP recognition model based on real-time object detection network exhibits excellent performance,and it can be applied to real-time ultrasound diagnosis,teaching and intelligent quality evaluation.

Objective To observe the correlations of conventional ultrasound and contrast-enhanced ultrasound(CEUS)features with expression level of Ki-67 of intrahepatic cholangiocarcinoma(ICC).Methods A total of 77 patients with pathologically confirmed ICC were retrospectively enrolled.According to the expression level of Ki-67 of target lesions,the patients were divided into high expression group(Ki-67≥20%,n=53)and low expression group(Ki-67＜20%,n=24).The features showed on conventional ultrasound and CEUS were compared between groups,and the variables being significantly different were analyzed with multivariate logistic regression to select ultrasonic features being correlated with Ki-67 expression level of ICC.Results The mean maximum diameter of ICC in high expression group was larger than that in low expression group([6.2±2.0]cm vs.[5.2±1.9]cm,P=0.041),and the percentage of ICC with maximum diameter>5 cm in high expression group was higher than that in low expression group(66.04%vs.33.33%,P=0.007).No significant difference of the lesions shape,border nor the internal echogenicity showed on conventional ultrasound was found between groups(all P＞0.05).The percentage of ICC with peripheral rim enhancement and enlargement after enhancement in high expression group were both higher than those in low expression group(both P＜0.05),but no significant difference of the enhancement pattern,the presence or absence of non-enhance area within the lesion nor the peak intensity of lesions was found between groups(all P＞0.05).The maximum diameter larger than 5 cm(OR=5.612,P=0.004)and peripheral rim enhancement(OR=3.880,P=0.025)were both independent factors for predicting high Ki-67 expression level of ICC.Conclusion ICC with the maximum diameter larger than 5 cm and peripheral rim enhancement on CEUS might indicate high expression level of Ki-67,which was helpful for clinical treatment decisions.

Objective:To investigate the epidemiological characteristics and prognosis of critically ill patients with sepsis combined with acute kidney injury (AKI) in intensive care unit (ICU) in Beijing, and to analyze the risk factors associated with in-hospital mortality among these critically ill patients.Methods:Data were collected from the Beijing AKI Trial (BAKIT) database, including 9 049 patients consecutively admitted to 30 ICUs in 28 tertiary hospitals in Beijing from March 1 to August 31, 2012. Patients were divided into non-AKI and non-sepsis group, AKI and non-sepsis group, non-AKI and sepsis group, AKI and sepsis group. Clinical data recorded included demographic characteristics, primary reasons for ICU admission, comorbidities, sequential organ failure assessment (SOFA), acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) within 24 hours of ICU admission, physiological and laboratory indexes, treatment in the ICU, AKI staging based on the Kidney Disease: Improving Global Outcomes (KDIGO), as well as the prognostic indicators including length of stay in ICU, length of stay in hospital, ICU and in-hospital mortality. The primary endpoint was discharge or in-hospital death. Multivariate Logistic regression analysis was used to investigate the risk factors for hospital death in ICU patients. Kaplan-Meier survival curve was drawn to analyze the cumulative survival of ICU patients during hospitalization.Results:A total of 3 107 critically ill patients were ultimately enrolled, including 1 259 cases in the non-AKI and non-sepsis group, 931 cases in the AKI and non-sepsis group, 264 cases in the non-AKI and sepsis groups, and 653 cases in the AKI and sepsis group. Compared with the other three group, patients in the AKI and sepsis group were the oldest, had the lowest mean arterial pressure (MAP), and the highest APACHEⅡscore, SOFA score, blood urea nitrogen (BUN), and serum creatinine (SCr) levels, and they also had the highest proportion of receiving mechanical ventilation, requiring vasopressor support, and undergoing renal replacement therapy (RRT), all P < 0.01. Of these 3 107 patients, 1 584 (51.0%) were diagnosed with AKI, and the incidence of AKI in patients with sepsis was significantly higher than in those without sepsis [71.2% (653/917) vs. 42.5% (931/2 190), P < 0.01]. The highest proportion of KDIGO 0 stage was observed in the non-sepsis group (57.5%), while the highest proportion of KDIGO 3 stage was observed in the sepsis group (32.2%). Within the same KDIGO stage, the mortality of patients with sepsis was significantly higher than that of non-sepsis patients (0 stage: 17.8% vs. 3.1%, 1 stage: 36.3% vs. 7.4%, 2 stage: 42.7% vs. 17.1%, 3 stage: 54.6% vs. 28.6%, AKI: 46.1% vs. 14.2%). The ICU mortality (38.7%) and in-hospital mortality (46.1%) in the AKI and sepsis group were significantly higher than those in the other three groups. Kaplan-Meier survival curves further showed that the cumulative survival rate of patients with AKI and sepsis during hospitalization was significantly lower than that of the other three groups (53.9% vs. 96.9%, 85.8%, 82.2%, Log-Rank: χ2 = 379.901, P < 0.001). Subgroup analysis showed that among surviving patients, length of ICU stay and total length of hospital stay were significantly longer in the AKI and sepsis group than those in the other three groups (both P < 0.01). Multivariate regression analysis showed that age, APACHEⅡscore and SOFA score within 24 hours of ICU admission, coronary heart disease, AKI, sepsis, and AKI combined with sepsis were independent risk factors for ICU mortality in patients (all P < 0.05). After adjusting for covariates, AKI, sepsis, and sepsis combined with AKI were significantly associated with higher ICU and in-hospital mortality, with the highest ICU mortality [adjusted odds ratio ( OR) = 14.82, 95% confidence interval (95% CI) was 8.10-27.12; Hosmer-Lemeshow test: P = 0.816] and in-hospital mortality (adjusted OR = 7.40, 95% CI was 4.94-11.08; Hosmer-Lemeshow test: P = 0.708) observed in patients with sepsis combined with AKI. Conclusions:The incidence of AKI is high in sepsis patients, and those with both AKI and sepsis have a higher disease burden, more abnormalities in physiological and laboratory indicators, and significantly increased ICU and in-hospital mortality. Among surviving patients, the length of ICU stay and total length of hospital stay are also longer in the AKI and sepsis group. Age, APACHEⅡscore and SOFA score within 24 hours of ICU admission, coronary heart disease, AKI, and sepsis are independent risk factors for in-hospital mortality in ICU patients.

Objective:To analyze the correlation of poorly differentiated cluster(PDC)grade with clinicopathological features and prognosis of patients with colon cancer.Methods:Hematoxylin-eosin-stained specimens and data from 102 patients with colon cancer who under-went surgery at the Affiliated Hospital of Anhui West Health Vocational College between December 2016 and July 2021 were analyzed in this study.The PDC grades of tumor tissues were determined in all colon cancer cases.Additionally,associations between the PDC grade and clinicopathological features of patients were analyzed via Chi-square test and Logistic regression analysis,whereas the association between the PDC grade and patient prognosis was evaluated using Cox regression analysis.Results:In total,52 cases were identified as PDC G1,14 as PDC G2,and 36 as PDC G3.Tumor budding(TB)was independently and positively associated with PDC,whereas tumor infiltrating lympho-cytes(TIL)were independently and negatively associated with PDC(all P<0.05).Lymph node metastasis or presence of cancerous nodules(hazard ratio[HR]=2.377;95%confidence interval[CI]=1.237-4.568;P=0.009),distant metastasis(HR=7.455;95%CI=2.597-21.399;P<0.001),and the PDC grade(HR=2.095;95%CI=1.099-3.994;P=0.025)were independent risk factors for colon cancer progression.Conclu-sions:Our findings suggest that both TIL and TB affect the colon cancer PDC grade.Therefore,evaluating the PDC grade in cancer tissues can facilitate the prognostic stratification of patients with colon cancer.

Objective To investigate the factors affecting survival of dilated cardiomyopathy(DCM)after treatment with decreased left ventricular ejection fraction(LVEF).Methods A total of 158 DCM patients with decreased LVEF treated in Huzhou First People's Hospital from June 2020 to June 2023 were selected and divided into death group(n=40)and survival group(n=1 18)according to their survival status.The clinical data of two groups were analyzed by Cox proportional risk regression model to analyze the factors affecting the survival of DCM with decreased LVEF after treatment.Results The age of patients in death group was significantly higher than that in survival group,and the combination of hypertension,New York Heart Association(NYHA)cardiac function grade Ⅳ,ventricular arrhythmia and left ventricular end diastolic diameter(LVEDD),left ventricular end systolic diameter(LVESD),and brain natriuretic peptide(BNP)were significantly higher than those in survival group,global longitudinal strain(GLS),standard deviation of RR interval(SDNN),standard deviation of the average RR interval(SDANN),the average standard deviation of RR interval(SDNNindex),root mean square of RR interval difference(rMSSD),the percentage of total number of adjacent RR intervals＞50ms to total heart rate(pNN50),end diastolic interventricular septal thickness(IVSd),left ventricular posterior wall diastolic thickness(LVPWD),stroke volume(SV),and cardiac output(CO)were significantly lower than those in survival group(P＜0.05).Cox regression analysis showed that age,combined hypertension,NYHA cardiac function grade,ventricular arrhythmia,GLS,SDNN,SDANN,SDNNindex,rMSSD,pNN50,LVEDD,LVESD and BNP were risk factors affecting the survival rate of DCM patients with decreased LVEF after treatment,IVSd and LVPWD were protective factors(P＜0.05).Conclusion DCM patients with decreased LVEF had a higher mortality rate,which was affected by multiple factors such as age,hypertension,NYHA cardiac function grade,ventricular arrhythmia,GLS,heart rate variability,LVEDD,LVESD,BNP,IVSd,LVPWD,etc.Targeted intervention should be given early to improve the survival rate of patients after treatment.

Colorectal cancer (CRC), as one of the most common gastrointestinal malignancy, is original from the epithelial/endothelial cells of colorectal tissues. CRC is one of the highest incidence and mortality rates of any malignancy in humans today. Moving forward the early diagnosis window of colorectal cancer, dynamic monitoring of the risk of postoperative recurrence and metastasis, early intervention is of great value in improving the diagnosis and treatment outcome of colorectal cancer. The clinical diagnosis of CRC via circulating tumor cells (CTC) has been considered as one of the fast, noninvasive, reproducible liquid biopsy methods, and it has been widely used in the early diagnosis, treatment monitoring and prognosis evaluation of colorectal cancer. This review systematically expounded the applied research values of CTC counting, protein expression (phosphatase of regenerating liver-3, matrix metalloproteinase, etc), molecular characterization (adenomatous polyp of colon, erb-b2 receptor tyrosine kinase, etc), mRNA expression profile and single cell sequencing in the diagnosis and treatment of colorectal cancer, in order to assist clinical in rational use of CTC monitoring indicators and provide support for improving the prognosis of colorectal cancer.

Objective:To investigate the clinical value of nutritional indexes including body mass index (BMI), albumin (ALB), nutrition risk screening 2002 (NRS 2002) and the nutrition risk in critically ill score (NUTRIC) in 28-day prognosis of patients with sepsis related acute kidney injury (AKI).Methods:A prospective cohort study was conducted. Patients with sepsis treated in the emergency intensive care unit (EICU) of China Rehabilitation Research Center from December 1, 2018 to December 1, 2020 were observed for 7 days. Patients with sepsis related AKI were enrolled in this study. The gender, age, BMI, basic diseases, shock, number of affected organs, length of hospital stay, ALB, mechanical ventilation (MV) and vasoactive drug use, sequential organ failure score (SOFA), rapid sequential organ failure score (qSOFA) and acute physiology and chronic health evaluationⅡ(APACHEⅡ) were recorded. The NRS 2002 score and NUTRIC score were calculated. Cox regression model was used to analyze the risk factors of 28-day mortality in patients with sepsis related AKI. The receiver operator characteristic curves (ROC curves) were drawn and the areas under the ROC curves (AUC) were calculated, and the value of BMI, ALB, NRS 2002 score and NUTRIC score was analyzed to predict 28-day mortality in patients with sepsis related AKI. Kaplan Meier survival curves were used to analyze the effects of NRS 2002 score and NUTRIC score stratification on the 28 day prognosis of patients with sepsis related AKI.Results:A total of 140 patients with sepsis related AKI were enrolled, including 73 survival patients and 67 died patients within 28 days. The 28-day mortality was 47.9% (67/140). BMI in the survival group was significantly higher than that in the death group [kg/m 2: 22.0 (19.5, 25.6) vs. 20.7 (17.3, 23.9), P < 0.05], and NRS 2002 score and NUTRIC score were significantly lower than those in the death group [NRS 2002 score: 5 (4, 6) vs. 7 (6, 7), NUTRIC score: 6 (5, 7) vs. 7 (6, 9), both P < 0.05]. The ALB of the survival group was slightly higher than that of the death group, but the difference was not statistically significant. Cox regression analysis showed that NRS 2002 score and NUTRIC score were independent risk factors for 28-day death in patients with sepsis related AKI. ROC curve analysis showed that NUTRIC score had the strongest predictive ability for 28-day death [AUC = 0.785, 95% confidence interval (95% CI) was 0.708-0.850], followed by NRS 2002 score (AUC = 0.728, 95% CI was 0.647-0.800), but there was no significant difference between them. Compared with NRS 2002 score, the predictive ability of BMI and ALB was poor. Kaplan-Meier curve analysis showed that the prognosis of patients with NRS 2002 score≥5 was significantly worse than that of patients with NRS 2002 score < 5 (28-day cumulative survival rate: 42.1% vs. 75.6%, Log-Rank test: 2 = 11.884, P = 0.001), and the prognosis of patients with NUTRIC score≥6 was significantly worse than that of patients with NUTRIC score < 6 (28-day cumulative survival rate: 40.4% vs. 86.1%, Log-Rank test: 2 = 19.026, P = 0.000). Conclusions:Patients with sepsis related AKI have high nutritional risk. Both NRS 2002 score and NUTRIC score have good predictive value for the prognosis of patients with sepsis related AKI, while BMI and ALB have low predictive value. Due to the complex calculation of NUTRIC score, NRS 2002 score may be more suitable for emergency department.

Objective:To investigate the predictive value of mid-regional proadrenomedullin (MR-proADM) on poor prognosis of low-risk patients with sepsis.Methods:This was a prospective cohort study. Patients with sepsis admitted to the Emergency Intensive Care Unit of China Rehabilitation Research Center from December 2018 to December 2020 were included in this study. The patients were divided into the low-risk group (SOFA≤7) and medium-high-risk group (SOFA>7) according to the sequential organ failure assessment (SOFA) score, and the clinical characteristics of the two groups were compared. Proportional hazards regression model (COX regression model) was used to investigate the risk factors of 28-day mortality in the low-risk and medium-high-risk group. The predictive ability of MR-proADM, C-reactive protein (CRP), lactic acid (Lac), interleukin-6 (IL-6), SOFA score, and acute physiology and chronic health evaluationⅡ (APACHE Ⅱ) score for the prognosis in each group was evaluated by receiver operating characteristic (ROC) curve. The outcomes of patients with different concentration of MR-proADM in the low-risk group were compared.Results:Totally 205 patients with sepsis were included, and the 28-day mortality was 41.0% (84/205). There were significant differences in the number of organ dysfunction, acute kidney injury, use of vasoactive drugs, Lac, IL-6, SOFA score and APACHEⅡ score between the two groups ( P<0.05). Cox regression model showed that age, MR-proADM, mechanical ventilation, IL-6 and APACHEⅡ score were the risk factors of 28-day death in the low-risk group, while MR-proADM, Lac, SOFA score and APACHEⅡ score were the risk factors of 28-day mortality in the medium-high-risk group. In each group, MR-proADM had a good predictive ability for the prognosis of patients with sepsis ( P<0.001). Especially in low-risk patients with sepsis, the predictive ability of MR-proADM was better than other indicators. Kaplan-Meier survival curve suggested that the patients with MR-proADM >2.53 nmol/L had worse prognosis than those with MR-proADM ≤2.53 nmol/L, and the difference was statistically significant ( P<0.001). In the low-risk group, the mortality of patients increased from 7.8% to 58.2% if MR-proADM >2.53 nmol/L. Conclusions:MR-proADM is a risk factor for 28-day mortality in patients with sepsis, and MR-proADM can early identify the poor prognosis of low-risk patients with sepsis.
