Objective: To investigate the clinicopathological characteristics and surgical outcomes of adrenal hemolymphangioma,so as to enhance the understanding of this disease. Methods: Clinical and pathological data of 8 patients with adrenal hemolymphangioma admitted to the Department of Urology of our hospital during Jan.2013 and Dec.2022 were retrospectively analyzed,and relevant literature was reviewed. Results: The patients included 5 males and 3 female,median age 54(25-75) years.Adrenal hemolymphangioma was detected in all patients in physical examinations without obvious symptoms.And 4 of the patients had a history of hypertension.Adrenal function test results showed no abnormalities.A total of 9 tumors were identified by imaging examination,including 1 unilateral multiple and 7 unilateral solitary tumors,with a median diameter of 3.6(1.0-5.4) cm.Posterior laparoscopic adrenal tumor resection was performed in 7 cases and robot-assisted laparoscopic adrenal tumor resection in 1 case；all of the tumors were completely removed.The median operation time was 77(53-115) min,median intraoperative blood loss 7.5(2.0-20.0) mL,and median postoperative hospital stay 4(1-7) d.Postoperative pathology showed interwoven deformed and dilated blood vessels and lymphatic vessels in the cystic tumors,with a large amount of lymphoid fluid,lymphocytes and red blood cells.Chronic lymphocyte infiltration was visible between the tube walls.The cystic cavity was partially connected,with flat endothelial cells lining.The pathological diagnosis was adrenal hemolymphangioma.During the median follow-up of 53.5(12.0-106.8) months,all patients recovered well,with stable blood pressure and no tumor recurrence or metastasis. Conclusion: Adrenal hemolymphangioma has no specific clinical symptoms.As adrenal functional tests show no obvious abnormalities,the diagnosis depends on pathological examinations.Popsterior laparoscopic or robot-assisted laparoscopic resection has good efficacy and prognosis.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

A retrospective analysis of the clinical data of seven acute B-lymphoblastic leukemia (B-ALL) patients with TCF3-HLF fusion gene-positive admitted to the First Affiliated Hospital of Soochow University from June 2017 to August 2022 was conducted to summarize their clinical features and prognoses. The seven B-ALL patients comprised four males and three females, with a median age of 18 (11-33) years. Five patients tested positive for CD33 expression, and four patients had a normal karyotype. Two patients had hypercalcemia at the initial diagnosis, and one patient developed hypercalcemia at relapse. Six patients presented with coagulation dysfunction at diagnosis. After induction chemotherapy, five out of seven patients achieved complete remission, of which four subsequently relapsed. Two patients did not achieve remission even after two rounds of induction chemotherapy, with one achieving complete remission after treatment with blinatumomab immunotherapy. Three patients underwent chimeric antigen receptor T cell therapy, whereas three patients subsequently underwent hematopoietic stem cell transplantation. Five patients died, while two patients survived with sustained complete remission. TCF3-HLF-positive B-ALL is rare and has a high relapse rate and poor prognosis.

Abstract: Objective Based on the results of previous studies that diabetic foot is the most common type of chronic wound in Hainan, the study aims to clarify the severity of diabetic foot residents and the risk factors of diabetic foot gangrene in Hainan Island, and to provide a scientific basis for reducing the incidence of amputation in diabetic foot patients. Methods A total of 457 diabetic foot patients from 19 hospitals in 11 cities and counties in Hainan Province were investigated from July 2022 to June 2023 using a survey design. The data collected included demographic characteristics, diabetes, and diabetic foot information. Counting data were described by frequency and percentage, and chi-square test was used for the comparison of differences between groups. A binary Logistic regression multi-factor analysis was used, and an incremental model was set up in the regression to test the impact of potential confounding factors on the results. Results The incidence of gangrene in diabetic foot patients in Hainan is 56.01% (95%CI: 51.21%-61.49%), which is higher than that in other areas. Univariate analysis showed that age, lifestyle habits, medication, comorbidities, family history, and wound infection are associated with the risk of diabetic foot gangrene. Multivariate logistic regression analysis further confirmed that the independent risk factors for diabetic foot gangrene are not receiving diabetes medication, having complications/complications of diabetes, and not checking both feet daily. No significant interaction between gender and the above factors was found in the subgroup analysis. Conclusions The incidence of gangrene in diabetic foot patients in Hainan is higher than that in other areas, and the risk factors are related to the lack of standardized, timely treatment, and patients' lack of knowledge about diabetes and diabetic foot. It is suggested to speed up the construction of wound treatment centers in primary hospitals, improve the treatment level of diabetic foot, pay attention to the education of diabetes and diabetic foot, and improve patients' compliance with treatment, so as to achieve early detection, timely diagnosis and treatment, and reduce the severity of diabetic foot and the risk of gangrene.

Objective: To study the value of unmethylated cytosine guanine dinucleotide oligodeoxynucleotide (DSP30) and IL-2 in the conventional cytogenetic (CA) detection of the chromosomal aberrations in chronic lymphocytic leukemia (CLL) . Methods: Bone marrow or peripheral blood cells of CLL patients were cultured with DSP30 plus IL-2 for 72 h, following which R-banding analysis was conducted. Fluorescence in situ hybridization (FISH) was performed in 85 patients. CA results were compared with data obtained by FISH. Results: Among 89 CLL patients, the success rate of chromosome analysis was 94.38% (84/89) . Clonal aberrations were detected in 51 patients (51/84, 60.71%) . Of them, 27 (27/51, 52.94%) were complex karyotype. Among 85 CLL patients tested by FISH, chromosomal abnormalities were detected in 74 (74/85, 87.06%) patients, of which 2 (2/74) patients were complex karyotypes, accounting for 2.70%. Of the 85 CLL patients examined by FISH, 50 had abnormal karyotype analysis, 30 had normal karyotype, 5 failed to have chromosome analysis. Among them, 25 cases showed clonal aberrations by FISH assay but normal by CA, and 4 cases were normal by FISH but displayed aberrations in chromosome analysis, and totally 78 (91.76%) cases with abnormality detected by the combination of the two methods. The frequency of 13q- abnormality detected by FISH was significantly higher than that by CA analysis (69.41%vs 16.67%, P<0.001) , while the frequency of 11q-,+12 and 17p- detected by two methods showed no significant difference (P>0.05) . The detection rate of complex abnormalities in conventional karyotype analysis was higher than that in FISH (50.98%vs 2.70%) . In addition, 11 low-risk and 9 intermediate-risk patients according to FISH results showed complex karyotype by cytogenetics, and were classified into high-risk cytogenetic subgroup. Conclusion DSP30 and IL-2 are effective in improving the detection rate of CA in CLL patients (60.71%) and CA is more effective to detect complex karyotype. However, FISH had a higher overall abnormality detection rate (87.06%) than CA, especially for 13q-. The combination of CA and FISH not only enhanced the detection rate of clonal aberrations to 91.76%, but also provided more precise prognosis stratification for CLL patients, thus to provide more information for clinical implication.

OBJECTIVE: To develop and validate radiomics models based on non-enhanced magnetic resonance (MR) imaging for differentiating chondrosarcoma from enchondroma. METHODS: We retrospectively evaluated a total of 68 patients (including 27 with chondrosarcoma and 41 with enchondroma), who were randomly divided into training group (=46) and validation group (=22). Radiomics features were extracted from TWI and TWI-FS sequences of the whole tumor by two radiologists independently and selected by Low Variance, Univariate feature selection, and least absolute shrinkage and selection operator (LASSO). Radiomics models were constructed by multivariate logistic regression analysis based on the features from TWI and TWI-FS sequences. The receiver-operating characteristics (ROC) curve and intraclass correlation coefficient (ICC) analyses of the radiomics models and conventional MR imaging were performed to determine their diagnostic accuracy. RESULTS: The ICC value for interreader agreement of the radiomics features ranged from 0.779 to 0.923, which indicated good agreement. Ten and 11 features were selected from the TWI and TWI-FS sequences to construct radiomics models, respectively. The areas under the curve (AUCs) of TWI and TWI-FS models were 0.990 and 0.925 in training group and 0.915 and 0.855 in the validation group, respectively, showing no significant differences between the two sequence-based models (>0.05). In all the cases, the AUCs of the two radiomics models based on TWI and TWI-FS sequences and conventional MR imaging were 0.955, 0.901 and 0.569, respectively, demonstrating a significantly higher diagnostic accuracy of the two sequence-based radiomics models than conventional MR imaging (<0.01). CONCLUSIONS The radiomics models based on TWI and TWI-FS non-enhanced MR imaging can be used for the differentiation of chondrosarcoma from enchondroma.

OBJECTIVE: To explore the clinical and laboratory characteristics of 5 patients with myeloid leukemia and t(12;22)(p13;q12). METHODS: Bone marrow cells were cultured for 24 h and analyzed by standard R-banding. Rearrangement of the MN1 gene was detected by fluorescence in situ hybridization (FISH) using dual color break-apart MN1 probes. MN1-ETV6 and ETV6-MN1 fusion genes were detected by reverse transcription polymerase chain reaction (RT-PCR). And the products were subjected to direct sequencing. RESULTS: Among the 5 patients, 2 had AML-M0, 2 had AML-M4, and 1 had CMML at the initial diagnosis. t(12;22)(p13;q12) was the primary abnormality among all patients. Rearrangements of MN1 gene were detected by FISH in all patients. MN1-ETV6 and ETV6-MN1 fusion genes were detected respectively in 4 and 3 patients. CONCLUSION t(12;22)(p13;q12) is a rare but recurrent chromosomal abnormality in myeloid leukemia, and is related to poor prognosis. allo-SCT is valuable for patients with t(12;22)(p13;q12).

Objective To explore the correlation between depressive symptoms and frailty,in order to provide evidence for prevention and relief of depressive symptoms in elderly inpatients.Methods A cross-sectional survey and comprehensive geriatric assessment(CGA)were conducted with 248 eligible elderly inpatients from December 2015 to February 2017 in our hospital.Depressive symptoms were assessed by the 5-Item Geriatric Depression Scale(GDS-5),and frailty was identified by the frailty phenotype method.Results In all respondents,50 (20.2 ％)patients showed depressive symptoms,93(37.5 ％)patients had pre-frailty and 39 (15.7 ％)patients had frailty.Correlation analysis showed that frailty degree,low grip strength,slow gait speed,low physical activity,fatigue,and weakness were all positively correlated with depressive symptoms in elderly inpatients (r =0.441,0.315,0.426,0.316,0.395 and 0.151,respectively,P ＜ 0.05).Logistic regression analysis showed that patients who had more severe frailty faced a much higher risk of developing depressive symptoms (OR=2.608,P＜0.05).Of the 5 indicators of frailty,slow gait speed and frailty also increased the risk of having depressive symptoms (OR =2.801 and 3.484,P ＜ 0.05).Conclusions Frailty degree,gait speed and fatigue are associated with increased risk of depression in the elderly.Depressive symptoms can be reduced in elderly inpatients with prevention and intervention of pre-frailty and frailty.

Objective To evaluate the clinical value of 3D printed modeling used to assist internal fixation for pelvic fractures.Methods The databases,Pubmed,EMBase,Cochrane library,CNKI,Wanfang and VIP,from initiation till August 2018,were searched for the controlled studies comparing surgery assisted by 3D printed modeling and conventional surgery in the treatment of pelvic fractures.The 2 groups were compared in terms of surgical time,blood loss,Matta score for reduction,Majeed score for functional recovery and complications.This meta-analysis was performed using software RevMan 5.3.Results A total of 6 relative controlled studies were included for this analysis involving 513 patients.There were 221 cases in the 3D printed modeling group and 292 ones in the conventional group.Our Meta-analysis showed that there were significant differences between the 2 groups in surgical time (MD =-48.11,95％ CI:-74.16 ～-22.06,P ＜0.05),blood loss (MD=-250.63,95％ CI:-337.42～-163.84,P ＜0.05) and Matta score for reduction (OR =1.85,95％ CI:1.07 ～ 3.20,P =0.03),favoring the 3D printed modeling group.No statistically significant difference was found between the 2 group in the rate of complications (OR =0.61,95％ CI:0.32 ～ 1.17,P =0.14).Conclusion Assistance with 3D printed modeling may help the surgery for pelvic fractures to shorten surgery time,decrease blood loss and improve reduction quality.

Objective? To investigate the health belief of colorectal cancer and its screening in relatives of patients with hereditary colorectal cancer,and to analyze its influencing factors. Methods? Totally 148 blood relatives of patients with hereditary colorectal cancer hospitalized in the Department of Colorectum of a Class ⅢGrade A hospital in Guangzhou from December 2016 to May 2018 were selected using convenient sampling, and investigated with the self-made general information questionnaire and Chinese Colorectal Cancer Health Belief Scale (CCCHBS). SPSS 20.0 was used for statistical analysis. Results? The colorectal cancer health belief of blood relatives of patients with hereditary colorectal cancer totaled (3.37±0.35) in which the perception and acceptance levels of screening benefits, health motives and self-efficacy of colorectal cancer were higher, while the perception levels of severity of colorectal cancer, barriers against colorectal screening and susceptibility were lower. Multivariate linear regression analysis revealed that household income per capita, educational background, with commercial medical insurance or not and the number of blood relatives with cancer were the influencing factors for health belief levels, which accounted for 41.9% of the total variance. Conclusions? The health belief in blood relatives of patients with hereditary colorectal cancer remain at a medium level. Medical and nursing workers should pay attention to the blood relatives of patients with hereditary colorectal cancer with lower educational background, lower household income and less blood relatives with cancer, take measures to improve their health belief levels, and facilitate colorectal cancer screening behaviors so as to prevent and control colorectal cancer in a better manner.
