Objective:To investigate the correlation between serum uric acid/high density lipoprotein cholesterol (URH) and diabetic nephropathy in patients with type 2 diabetes mellitus (T2DM) .Methods:According to urinary albumin creatinine ratio, 171 patients with T2DM were divided into simple T2DM group (group A1), microalbuminuria group (group A2) and macroalbuminuria group (group A3). The general data, HbA1c, biochemical indices were compared, and URH was calculated.Results:The systolic blood pressure, diastolic blood pressure, SUA, TG and URH of A1 group were lower than those of the other two groups [ (129.7±15.78) vs (141.65±16.04) vs (147.31±17.01) mmHg, (78.9±10.71) vs (83.79±10.67) vs (84.61±12.19) mmHg, 291.5 (253.75, 351.25) vs 346 (280, 409) vs 344.5 (274.75, 425.75) μmol/L, 26.12 (19.71,32.96) vs 33.45 (26.55,42.2) vs 33.45 (26.55,42.2) ] ( P<0.05). HDL-C was higher than those of the other two groups [1.19 (1.02,1.29) vs1.02 (0.87,1.21) vs 1.07 (0.93,1.25) mmol/L] ( P<0.05), the course of disease and SCr of group A3 were higher than those of the other two groups [10.5 (7.25, 15) vs 8.5 (4,12) vs 8 (3,11) years; 82.5 (70.57,101.75) vs 66 (52.75,73.75) vs 64 (51, 84) μmol/L ] ( P<0.05), and eGFR was lower than those of the other two groups [91.63 (67.09, 112.21) vs 116.7 (96.6, 142.53) vs 109.85 (85.64, 152.39) ml/min/1.73 m 2] ( P<0.05). There were no significant differences in gender, smoking history, drinking history, age, BMI, TC, LDL-C, BUN, FPG or HbA1c among different groups (P> 0.05). Correlation analysis showed that the course of disease, systolic blood pressure, diastolic blood pressure, TG, SUA, URH were positively correlated with UACR, while HDL-C was negatively correlated with UACR. Logistic regression analysis showed that course of disease was a risk factor for macroproteinuria, while systolic blood pressure and URH were risk factors for microproteinuria and macroproteinuria. ROC curve showed that the AUC value of URH was the highest, and the accuracy rate was 69.3%. Conclusions:URH is closely related to the occurrence of DKD and is a risk factor of DKD. Dynamic monitoring of URH in T2DM patients is helpful for early screening of DKD, which is superior to SUA and HDL-C.

OBJECTIVE: To explore the regulatory mechanism of human hepatocyte apoptosis induced by lysosomal membrane protein Sidt2 knockout. METHODS: The Sidt2 knockout (Sidt2^-/-) cell model was constructed in human hepatocyte HL7702 cells using Crispr-Cas9 technology.The protein levels of Sidt2 and key autophagy proteins LC3-II/I and P62 in the cell model were detected using Western blotting, and the formation of autophagosomes was observed with MDC staining.EdU incorporation assay and flow cytometry were performed to observe the effect of Sidt2 knockout on cell proliferation and apoptosis.The effect of chloroquine at the saturating concentration on autophagic flux, proliferation and apoptosis of Sidt2 knockout cells were observed. RESULTS: Sidt2^-/- HL7702 cells were successfully constructed.Sidt2 knockout significantly inhibited the proliferation and increased apoptosis of the cells, causing also increased protein expressions of LC3-II/I and P62(P < 0.05) and increased number of autophagosomes.Autophagy of the cells reached a saturated state following treatment with 50 μmol/L chloroquine, and at this concentration, chloroquine significantly increased the expressions of LC3B and P62 in Sidt2^-/- HL7702 cells. CONCLUSION Sidt2 gene knockout causes dysregulation of the autophagy pathway and induces apoptosis of HL7702 cells, and the latter effect is not mediated by inhibiting the autophagy-lysosomal pathway.

AIM: To investigate the effect of low-dose aspirin on primary prevention of non-fatal myocardial and cerebral infarction in patients with type 2 diabetes mellitus. METHODS: From January 2015 to December 2016,40-90 years old patients with type 2 diabetes were treated in the Department of Endocrinology of Yijishan Hospital of Wannan Medical College for more than 2 times (the interval of hospitalization was more than 3 months) , we use the hospital's his system to search out-patient and in-patient files, patients were divided into aspirin group and non-aspirin group according to the use of low-dose aspirin within 1 year after the first visit, the basic data of the first visit were collected: name, sex, age, course of diabetes, systolic and diastolic blood pressure, patients were recorded for laboratory markers including fasting blood glucose, glycated hemoglobin, triglyceride, total cholesterol, Low-density lipoprotein, high-density lipoprotein, creatinine, and platelets, complications such as hypertension, coronary heart disease, atrial fibrillation, hyperlipidemia, diabetic nephropathy and arteriosclerosis were recorded. A Chi square test and a Cox proportional hazard model were used to compare baseline data and cerebrovascular disease after the first use of aspirin. RESULTS: Of the 4 176 patients, 2 137 were type 2 diabetes, 417 were eligible for admission, including 198 males, 219 females, 224 aspirin users and 193 non-users. There was no significant difference in the incidence of cerebral infarction between the aspirin group and the non-aspirin group (χ2=0.820, P=0.365). The incidence of non-fatal myocardial infarction was lower than that of the aspirin non-aspirin group (χ2=10.099, P=0.01) , the incidence of massive hemorrhage was significantly higher than that of aspirin-free group χ2=5.425, P=0.020) . In a subgroup analysis of aspirin use, patients younger than 60 years of age had a lower incidence of ischemic stroke (cerebral infarction) and a risk ratio of 0.428 (95%CI: 0.255-0.719, P=0.001) compared with patients older than 60 years of age, the incidence of cerebral infarction was higher in female patients with a risk ratio of 1.574 (95%CI: 1.018-2.434, P=0.041). CONCLUSION: In this study of patients with type 2 diabetes, low-dose aspirin reduced the incidence of nonfatal myocardial infarction but had no significant effect on the incidence of nonfatal ischemic stroke, and significantly increase the incidence of major bleeding events, we should reconsider the use of low-dose aspirin as a potential benefit of nonfatal cerebral infarction in patients with type 2 diabetes.

Objective:To explore the prognostic value of lymphocyte subsets in adult hemophagocytic syndrome (HPS).Methods:A total of 172 adult HPS patients diagnosed in 8 medical centers from January 2013 to August 2020 were selected for the study, of whom 87 were male (50.6%, 87/172), and 85 were female (49.4%, 85/172), with 68 survivors and 104 deaths. The clinical data were summarized, and variables such as lymphocyte subsets, immunoglobulin characteristics and fibrinogen were retrospectively analyzed, and the correlation between the mentioned variables and patient prognosis was analyzed. The optimal cut-off values of continuous variables were calculated by MaxStat, and the prognostic factors of HPS patients were screened based on the Cox proportional hazard regression model.Results:The median age of HPS patients was 56 (42, 66) years old, and the 5-year cumulative survival rate was 37.4% (37.4/100). The median age, platelet and albumin were 48 (27, 63) years, 84×10 9/L and 32.3 g/L in the survival group, and 59 years, 45.5×10 9/L, and 27.3 g/L in the death group, respectively. The differences between the two groups was statistically significant ( Z=?3.368, P=0.001; Z=?3.156, P=0.002; Z=?3.431, P=0.001). Patients with differentiated cluster 8+(CD8+)<11.1%, CD3+<64.9%, CD4+>51%, and CD4/CD8 ratio>2.18 had poor prognosis (χ 2=7.498, P=0.023; χ 2=4.169, P=0.041; χ 2=4.316, P=0.038; χ 2=9.372, P=0.002). Multivariable analysis showed that CD4/CD8 ratio, age, fibrinogen and hemoglobin were independent prognostic factors in HPS patients ( HR=2.435, P=0.027; HR=5.790, P<0.001; HR=0.432, P=0.018; HR=0.427, P=0.018). Conclusion:Peripheral blood lymphocyte subsets can be used to evaluate the prognosis of patients with HPS; CD4/CD8 ratio, age, fibrinogen, and hemoglobin are independent prognostic factors in HPS patients.

Objective:To explore the prognostic influencing factors of adult lymphoma-associated hemophagocytic syndrome (LAHS) based on multicenter data.Methods:The clinical data of 86 LAHS patients diagnosed in 9 medical centers of Huaihai Lymphoma Working Group from January 2015 to August 2020 were retrospectively analyzed. The optimal cut-off value of continuous variables was obtained based on MaxStat algorithm. Cox proportional hazard regression model was used for univariate and multivariate analyses. Kaplan-Meier method was used for survival analysis, and log-rank test was performed.Results:Among the 86 adult LAHS patients, 50 (58.1%) were males and 36 (41.9%) were females, the median age of the patients was 57 years old (19-76 years old), and the median overall survival (OS) time was 1.67 months (95% CI 0.09- 3.24 months). The most common pathologic type was diffuse large B-cell lymphoma (58 cases, 67.44%). Based on MaxStat algorithm, the optimal cut-off values of age, albumin, serum creatinine, lactate dehydrogenase, fibrinogen and platelet count were 64 years old, 30.1 g/L, 67 μmol/L, 1 045 U/L, 4.58 g/L and 72×10 9/L, respectively. Multivariate analysis showed that patient's age, lactate dehydrogenase, albumin and fibrinogen levels were independent influencing factors for OS (all P < 0.05). Conclusions:LAHS is dangerous and progresses quickly. Patients with age ≥ 64 years old, lactate dehydrogenase ≥ 1 045 U/L, fibrinogen ≥ 4.58 g/L and albumin < 30.1 g/L have poor survival.

Objective:Factors influencing the prognosis of hemophagocytic lymphohistiocytosis (HLH) in adults were analyzed based on multicentric data.Methods:Clinical data of 124 adult patients with HLH diagnosed in eight medical centers in the Huaihai Lymphoma Working Group from March 2014 to July 2020 were collected. The optimal truncation value of continuous variables was obtained based on the Maxstat algorithm, X-Tile software, and restricted cubic spline. Cox proportional risk regression model was used to construct the adult HLH risk prediction model, and the visualization of the model was realized through the histogram. The bootstrap resampling method was used to verify the model, C-index and calibration curve was used to verify the histogram, and the prediction accuracy was checked. Kaplan-Meier analysis was used to calculate the survival rate and draw the survival curve. Furthermore, the differences between groups were tested by log-rank.Results:The median age of the 124 patients was 55 (18-84) years, including 61 (49.19%) males. The most common etiology was infection. Serum ferritin increased in 110 cases (88.71%) , hepatosplenomegaly in 57 cases (45.97%) . Of the 124 patients, 77 (62.10%) died, and the median survival time of the patients was 7.07 months. Univariate results showed that the prognosis of adult HLH was influenced by sex, age, fibrinogen, serum creatinine, alanine aminotransferase, and albumin ( P<0.05) . The results of multivariate analysis showed that gender, platelet, albumin, alanine aminotransferase, and treatment regimens were independent influencing factors for prognosis. Based on the above five risk factors, the prediction model of the histogram was established, and the C-index of the model was 0.739. Finally, the calibration chart showed good consistency between the observed and predicted values of HLH. Conclusion:The prognosis of the adult hemophagocytic syndrome is influenced by many factors. Gender, platelet, albumin, alanine aminotransferase, and treatment regimens are independent risk factors. Therefore, the established histogram provides a visual tool for clinicians to evaluate the prognosis of adult HLH.

Objective:To explore the development trend of the combination of medical treatment and endowment and nursing by analyzing the keywords related to the combination of medical treatment and endowment and nursing in China from 2005 to 2017.Methods:Relevant articles about the combination of medical treatment and endowment which were published up to April 22, 2018 were retrieved from Wanfang, CNKI and VIP databases, and descriptive statistical methods were used to analyze the publication sources, number of keywords, word frequency, value of popularity, word meaning, etc.Results:Totally 5 704 articles were identified, and 1 655 were left after screening. The research on nursing started late among all researches on the combination of Chinese medical treatment and endowment, and there were few literatures, which had not received widespread attention from nursing journals. The proportion of Chinese nursing-related research in the combination of medical treatment and endowment was low. The keyword most concerned about was "senior caregivers". There was a lacking of technical and professional nursing research as well as specific discussions related to home care for the elderly.Conclusions:We should promote multi-angle and multi-level systematic nursing research, strengthen professional research in the combination of medical treatment and endowment and home care for the elderly, and provide technical support and practical basis for improving China's knowledge system of "the combination of medical treatment and endowment", and achieving a win-win situation for healthcare providers, caregivers, nurses and patients.
