Objective To investigate the expression of angiopoietin 1 and 2(Ang1,Ang2)in diffuse large B-cell lymphoma(DLBCL)and its survival prognosis analysis.Methods Peripheral blood was collected from 32 patients with initially diagnosed DLBCL and 30 healthy volunteers(the health control group),and the serum Ang1 and Ang2 levels were detected by ELISA.The biopsy tissues from DLBCL patients and the resec-ted normal lymph node biopsy tissues in neck surgery of 25 patients with non-tumor lesions(the control group)were taken as the specimens.The immunohistochemistry was used to detect the expression of CD34 in lymphoid tissues and the microvessel density was calculated;the statistical analyses were carried out by combi-ning with the clinical characteristics of the DLBCL patients and the follow-up data.Results The serum Ang1 level in initially diagnosed DLBCL was higher than that in the healthy control group[(36.22±9.12)ng/mL vs.(30.92±13.37)ng/mL],and the serum Ang2 level in initially diagnosed DLBCL was higher than that in the healthy control group[(28.42±10.78)ng/mL vs.(23.81±3.68))ng/mL],and the differences were sta-tistically significant(P＜0.05).CD34 was highly expressed in the lymphoma tissues of the patients with DL-BCL,whereas CD34 in normal lymph node tissues was weakly expressed;the microvessel density count in the DLBCL group was increased compared with the normal lymph node group(25.5±4.4 vs.13.2±3.0,P＜0.05).The Ang1 expression level had no significant correlation with the gender,age,IPI score,clinical stage and COO subtype.The Ang2 expression was correlated with the clinical stage,Ang2 was lowly expressed in the patients with stage Ⅰ-Ⅱ DLBCL,while which was highly expressed in the patients with stage Ⅲ-Ⅳ(P＜0.05);Ang2 had no significant correlation with the gender,age,IPI score and COO subtype.The OS time had no significant difference between the patients with Ang1 low expression and the patients with Ang1 high expression(25.86 months vs.23.11 months,P=0.722);the OS time in the patients with Ang2 low ex-pression was significantly higher than in the patients with high Ang2 expression(32.24 months vs.17.66 months,P=0.002).In the univariate analysis,Ann Arbor stage,IPI score and Ang2 all were the prognostic factors affecting the patients'OS,while gender,age and Ang1 had no significant correlation with the patients'OS.In Cox multifactorial analysis,the Ann Arbor stage,IPI score and Ang2 all were the independent prog-nostic factors affecting the patients'OS.prognostic factors.Conclusion Ang1 and Ang2 are highly expressed in DLBCL patients and promote lymphoma angiogenesis;Ang2 affects the survival prognosis of DLBCL patients.

Objective: To prospectively compare single-shot (SS) echo-planar imaging (EPI) and field-of-view optimized and constrained undistorted single-shot multiplexed sensitivity-encoding (FOCUS MUSE) for diffusion-weighted imaging (DWI) in evaluating thyroid-associated ophthalmopathy (TAO). Materials and Methods: SS EPI and FOCUS MUSE DWIs were obtained from 39 patients with TAO (18 male; mean ± standard deviation: 48.3 ± 13.3 years) and 26 healthy controls (9 male; mean ± standard deviation: 43.0 ± 18.5 years). Two radiologists scored the visual image quality using a 4-point Likert scale. The image quality score, signal-to-noise ratio (SNR), contrast-tonoise ratio (CNR), and apparent diffusion coefficient (ADC) of extraocular muscles (EOMs) were compared between the two DWIs. Differences in the ADC of EOMs were also evaluated. The performance of discriminating active from inactive TAO was assessed using receiver operating characteristic curves. The correlation between ADC and clinical activity score (CAS) was analyzed using Spearman correlation. Results: Compared with SS EPI DWI, FOCUS MUSE DWI demonstrated significantly higher image quality scores (P < 0.001), a higher SNR and CNR on the lateral rectus muscle (LRM) and medial rectus muscle (MRM) (P < 0.05), and a non-significant difference in the ADC of the LRM and MRM. Active TAO showed higher ADC than inactive TAO and healthy controls with both SS EPI and FOCUS MUSE DWIs (P < 0.001). Inactive TAO and healthy controls did not show a significant ADC difference with both DWIs. Compared with SS EPI DWI, FOCUS MUSE DWI demonstrated better discrimination of active from inactive TAO (AUC:0.925 vs. 0.779; P = 0.007). The ADC was significantly correlated with CAS in SS EPI DWI (r = 0.391, P < 0.001) and FOCUS MUSE DWI (r = 0.645, P < 0.001). Conclusion FOCUS MUSE DWI provides better images for evaluating EOMs and better performance in diagnosing active TAO than SS EPI DWI. The application of FOCUS MUSE will facilitate the DWI evaluation of TAO.

‍Hepatitis E virus （HEV） infection can cause acute， fulminant， and chronic hepatitis and is thus a worldwide health problem. The general population has no obvious symptoms or only mild symptoms after HEV infection， and most symptoms are self-limited and are easily ignored in clinical diagnosis. Previous reports have shown that HEV infection can cause dysfunction in multiple systems， especially the blood system， in which it often leads to a series of adverse outcomes. Comprehensive evaluation， early diagnosis， and early intervention of these HEV-related diseases will greatly reduce the medical burden of individuals and society. With reference to the previous reports， this article reviews the blood system diseases associated with HEV infection.

Objective:To analyze the clinical characteristics of elderly patients with papillary thyroid cancer(PTC)by age grouping.Methods:The patients were divided into three groups according to age at diagnosis: old(≥60 years, 90 cases), middle(40-59 years, 359 cases)and young patients(<40 years, 203 cases). The clinical data of 652 patients with PTC who were admitted to the Department of Thyroid Surgery of Beijing Hospital from December 2019 to December 2021 were retrospectively analyzed.The patients were divided into elderly group(≥60 years old, 90 cases), middle-aged group(40-59 years old, 359 cases)and young group(<40 years old, 203 cases). The clinical characteristics, ultrasound characteristics and invasion-related factors of patients in different groups were analyzed by statistical methods.Results:Compared with the young and middle-aged group, the elderly patients with PTC had a higher proportion of microcarcinoma(75.6%, 75.2%, 61.4%, χ2=13.054, P=0.001), less cervical lymph node metastasis(24.4%, 34.3%, 58.1%, χ2=41.650, P<0.001), and lower proportion of metastatic lymph nodes(0.08, 0.14, 0.24, χ2=40.618, P<0.001). There was no significant difference in tumor location and extra glandular invasion among the three age groups(35.56%, 36.2%, 38.4%, χ2=0.959, P=0.545). Conclusions:Compared with the young and middle-aged groups, PTC showed low invasiveness in the elderly population.In addition to surgical treatment, for elderly patients with low-risk clinical characteristics, it is worth performing a further study on whether careful observation or palliative treatment can be selected after comprehensive evaluation.

Cases in pathological stage N0, N1, N2, N3 were 19, 44, 85, 107 of the patients with the time to postoperative recurrence and metastasis ≤5 years, versus 12, 5, 18, 8 of the patients with the time to postoperative recurrence and metastasis >5 years, showing a significant difference in pathological N staging between them ( Z=-3.34, P<0.05). Further analysis showed significant differences in cases in pathological stage N0 and N3 ( χ2=16.52, 8.47, P<0.05) but no significant difference in cases in pathological stage N1 or N2 ( χ2=0.85, 1.18, P>0.05). The median overall survival time was 81 months after surgery and 10-year overall survival rate was 46.1% of 652 patients. The 10-year overall survival rates of patients in TNM stage Ⅱ and Ⅲ were 59.6% and 37.5%, respectively, showing a significant difference between them ( χ2=35.29, P<0.05). In further analysis, the 10-year overall survival rates of patients in pathological TNM stage ⅡA, ⅡB, ⅢA, ⅢB and ⅢC were 65.6%, 55.8%, 46.9%, 37.1% and 24.0%, respectively, showing a significant difference between them ( χ2=55.06, P<0.05). The 10-year overall survival rates of patients in patholo-gical stage T2, T3 and T4a were 55.2%, 46.5% and 41.5%, respectively, showing a significant difference between them ( χ2=8.39, P<0.05). The 10-year overall survival rates of patients in patholo-gical stage N0, N1, N2 and N3 were 63.7%, 56.2%, 48.5% and 26.4%, respectively, showing a signifi-cant difference between them ( χ2=54.89, P<0.05). (5) Prognostic factors analysis: results of univariate analysis showed that age, maximum diameter of tumor, degree of tumor differentiation as low or undifferentiated, pathological TNM staging, pathological T staging, pathological stage N2 or N3, post-operative chemotherapy were related factors for the 10-year overall survival rate of locally advanced gastric cancer patients undergoing laparoscopic D 2 radical distal gastrectomy ( hazard ratio=1.45, 1.64, 1.37, 2.05, 1.30, 1.68, 3.08, 0.56, 95% confidence interval as 1.15-1.84, 1.32-2.03, 1.05-1.77, 1.62-2.59, 1.05-1.61, 1.17-2.42, 2.15-4.41, 0.44-0.70, P<0.05). Results of multivariate analysis showed that maximum diameter of tumor >4 cm, low-differentiated or undifferentiated tumor, pathological TNM stage Ⅲ were independent risk factors for the 10-year overall survival rate of locally advanced gastric cancer patients undergoing laparoscopic D 2 radical distal gastrectomy ( hazard ratio=1.48,1.44, 1.81, 95% confidence interval as 1.19-1.84, 1.11-1.88, 1.42-2.30, P<0.05) and postoperative chemotherapy was a independent protective factor for the 10-year overall survi-val rate of locally advanced gastric cancer patients undergoing laparoscopic D 2 radical distal gastrec-tomy ( hazard ratio=0.57, 95% confidence interval as 045-0.73, P<0.05). Conclusions:Laparoscopic assisted D 2 radical distal gastrectomy for locally advanced gastric cancer has satisfactory 10-year oncologic outcomes. A high proportion of patients in pathological TNM stage Ⅲ, pathological stage T4a, pathological stage N3 have the time to postoperative recurrence and metastasis ≤5 years, whereas a high proportion of patients in pathological TNM stage Ⅱ or pathological stage N0 have the time to postoperative recurrence and metastasis >5 years. Maximum diameter of tumor >4 cm, low-differentiated or undifferentiated tumor, pathological TNM stage Ⅲ are independent risk factors for the 10-year overall survival rate of locally advanced gastric cancer patients undergoing laparos-copic D 2 radical distal gastrectomy. Postoperative chemotherapy is a independent protective factor for the 10-year overall survival rate of locally advanced gastric cancer patients undergoing laparos-copic D 2 radical distal gastrectomy.

The Kaplan-Meier method was used to calculate survival rates and draw survival curves. The Log-Rank test was used for survival analysis. The Logistic regression model was used to analyze the factors affecting postoperative early complications. The COX proportional hazard model was used for univariate and multivariate analyses of factors affecting the 3-year recurrence-free survival rate of patients. Multivariate analysis used stepwise regression to include variables with P<0.05 in univariate analysis and variables clinically closely related to prognosis. Results:(1) Age distribution, comor-bidities and ACCI status of patients. Of the 242 patients, there were 28 cases with age <50 years, 68 cases with age of 50 to 59 years, 113 cases with age of 60 to 69 years, 33 cases with age of 70 to 79 years. There was 1 patient combined with mild liver disease, 1 patient combined with diabetes of end-organ damage, 2 patients combined with peripheral vascular diseases, 2 patients combined with peptic ulcer, 6 patients combined with congestive heart failure, 8 patients combined with chronic pulmonary diseases, 9 patients with diabetes without end-organ damage. The ACCI of 242 patients was 2 (range, 0-4). (2) The grouping of ACCI and comparison of clinicopathological characteristics of patients in each group. Results of X-Tile software analysis showed that ACCI=3 was the best grouping threshold. Of the 242 patients, 194 cases with ACCI <3 were set as the low ACCI group and 48 cases with ACCI ≥3 were set as the high ACCI group, respectively. Age, body mass index, cases with preoperative comorbidities, cases of American Society of Anesthesiologists classification as stage Ⅰ, stage Ⅱ, stage Ⅲ, tumor diameter, cases with tumor histological type as signet ring cell or poorly differentiated adenocarcinoma and cases with tumor type as moderately or well differentiated adenocarcinoma, cases with tumor pathological T staging as stage T1, stage T2, stage T3, stage T4, chemotherapy cycles were (58±9)years, (22.6±2.9)kg/m 2, 31, 106, 85, 3, (4.0±1.9)cm, 104, 90, 16, 29, 72, 77, 6(4,6) in the low ACCI group, versus (70±4) years, (21.7±2.7)kg/m 2, 23, 14, 33, 1, (5.4±3.1)cm, 36, 12, 3, 4, 13, 28, 4(2,5) in the high ACCI group, showing significant differences in the above indicators between the two groups ( t=-14.37, 1.98, χ2=22.64, Z=-3.11, t=-2.91, χ2=7.22, Z=-2.21, -3.61, P<0.05). (3) Incidence of postoperative early complications and analysis of factors affecting postoperative early complications. Of the 242 patients, 33 cases had postoperative early complications, including 20 cases with local complications and 16 cases with systemic complica-tions. Some patients had multiple complications at the same time. Of the 20 patients with local complications, 12 cases had abdominal infection, 7 cases had anastomotic leakage, 2 cases had incision infection, 2 cases had abdominal hemorrhage, 2 cases had anastomotic hemorrhage and 1 case had lymphatic leakage.

Results of Logistic regression analysis showed that ACCI was a related factor for postoperative early complications of gastric cancer patients undergoing laparoscopic radical gastrectomy [ odds ratio=2.32, 95% confidence interval ( CI) as 1.04-5.21, P<0.05]. (4) Follow-up. All the 242 patients were followed up for 36(range,1?46)months. During the follow-up, 53 patients died and 13 patients survived with tumor. The 3-year recurrence-free survival rate of the 242 patients was 73.5%. The follow-up time, cases died and cases survived with tumor during follow-up, the 3-year recurrence-free survival rate were 36(range, 2-46)months, 29, 10, 80.0% for the low ACCI group, versus 35(range, 1-42)months, 24, 3, 47.4% for the high ACCI group. There was a significant difference in the 3-year recurrence-free survival rate between the two groups ( χ2=30.49, P<0.05). (5) Analysis of factors affecting the 3-year recurrence-free survival rate of patients. Results of univariate analysis showed that preoperative comorbidities, ACCI, tumor diameter, histological type, vascular invasion, lymphatic invasion, neural invasion, tumor pathological TNM staging, postoperative early complications were related factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy [ hazard ratio ( HR)=2.52, 3.64, 2.62, 0.47, 2.87, 1.90, 1.86, 21.77, 1.97, 95% CI as 1.52-4.17, 2.22-5.95, 1.54-4.46, 0.27-0.80, 1.76-4.70, 1.15-3.12, 1.10-3.14, 3.01-157.52, 1.11-3.50, P<0.05]. Results of multivariate analysis showed that ACCI, tumor pathological TNM staging, adjuvant chemotherapy were indepen-dent influencing factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy ( HR=3.65, 11.00, 40.66, 0.39, 95% CI as 2.21-6.02, 1.40-86.73, 5.41-305.69, 0.22-0.68, P<0.05). Conclusions:ACCI is a related factor for post-operative early complications of gastric cancer patients undergoing laparos-copic radical gastrectomy. ACCI, tumor pathological TNM staging, adjuvant chemotherapy are indepen-dent influencing factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy.

【Objective】 To study the annual financial expenditure in blood stations with different scales, and to establish the regression equation between blood collection units and total expenditure. 【Methods】 The annual total expenditure, the per capita cost of serving population, as well as the collection units of whole blood and apheresis platelet of 24 blood stations were collected. The financial expenditure required for collecting 10 000U blood was calculated.The statistical analysis was carried out with SPSS statistical software. 【Results】 From 2017 to 2020, the total annual financial expenditure of 24 blood stations showed an upward trend. The total expenditure among blood stations was different. The per capita cost of servicing population in the areas where the 24 blood stations were located had been increasing year by year. The 24 blood stations were divided into two grades according to the blood collection volume as 50 000 U, and the relationship equation between the blood collection volume and the annual total expenditure had been established. After testing, each equation was effective(P<0.05); There was no difference in the financial expenditure required for collecting 10 000U blood among blood stations with different scales. 【Conclusion】 From 2017 to 2020, the blood stations with an annual collection volume more than 50 000 U demonstrated a higher financial expenditure and the per capita cost of serving population than those <50 000 U. The blood collection volume of blood stations is significantly correlated with the annual total expenditure and the per capita cost of serving population.
