Objective:To investigate the relationship of plasma cholinesterase (ChE) with triglyceride (TG) levels in newly diagnosed patients with type 2 diabetes (T2DM).Methods:Clinical data and biochemical parameters of 321 patients with newly diagnosed T2DM admitted to the Department of Endocrinology of People′s Hospital of Shanghai Putuo from January 2018 to June 2020 were retrospectively collected. The patients were classified into four groups based on the plasma ChE level: Q1group ( n=81, <6 915 U/L), Q2 group ( n=80, 6 916-8 268 U/L), Q3 group ( n=80, 8 269-9 578 U/L), and Q4 group ( n=80, ≥9 579 U/L). The correlation of plasma ChE with TG level was analyzed. Results:With the increased ChE level, TG level significantly increased ( P<0.001). Correlation analysis showed that ChE was positively correlated with body weight, body mass index (BMI), TG, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), uric acid (UA), alanine aminotransferase (ALT), aspartate aminotransferase (AST)( r=0.35, 0.39, 0.35, 0.31, 0.27, 0.24, 0.25, 0.11, P<0.05, P<0.01 or P<0.001)while negatively correlated with age, systolic blood pressure, blood urea nitrogen (BUN), creatinine, and glycated albumin (GA)( r=-0.46、-0.14、-0.20、-0.14、-0.21, P<0.05 or P<0.001). Multivariate stepwise regression analysis showed that ChE was an independent risk factor for TG ( β=0.270, P<0.001). Logistic Multivariate regression analysis showed that after adjustment for sex, age, body weight, hemoglobin, leukocytes, total protein, albumin, globulin, ALT, BUN, creatinine, uric acid, smoking history, drinking history, HbA 1C, GA, TC, and LDL-C, the risk of hypertriglyceridemia in Q4 was 6.024 folds higher than Q1 group ( P=0.011). With the TG (1.70 mmol/L) as cut-off value, the optimal cut-off point of the ChE was 7 801 U/L, as calculated by receiver operating characteristic(ROC) curve analysis of ChE and hypertriglyceridemia. Conclusions:ChE level is positively correlated with TG in newly diagnosed patients with T2DM.

Objective:To investigate the relationship between normal plasma fibrinogen(FIB)levels and disease duration in elderly patients with type 2 diabetes mellitus(T2DM).Methods:Clinical data and biochemical test results of 1 116 elderly subjects with T2DM admitted to the Department of Endocrinology of Shanghai Tianyou Hospital from January 2016 to October 2019 were retrospectively collected and analyzed.Subjects were classified into four groups based on the duration of DM: the Q1 group(n=276, < 2.0 years), the Q2 group(n=278, 2.0-7.9 years), the Q3 group(n=280, 8.0-13.9 years)and the Q4 group(n=282, ≥ 14.0 years). The correlation between FIB and the duration of DM was analyzed.Results:With the prolongation of DM duration, FIB levels increased significantly( P<0.05). Pearson correlation analysis showed that the duration of DM was positively correlated with FIB, age and serum creatinine( P<0.01). Multiple stepwise regression analysis showed that the duration of DM was an independent factor for FIB( β=0.104, P<0.01). Logistic multiple regression analysis showed that after adjusting for sex, age, body mass index, systolic pressure, diastolic pressure, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, serum creatinine, alanine aminotransferase, fasting plasma glucose, glycosylated hemoglobin, smoking and drinking, the risk of hyperfibrinogenemia was 2.436 and 2.104 times higher, respectively, in Group Q4 and Group Q3 than in Group Q1(95% CI: 1.317-4.507, P<0.01; 95% CI: 1.144-3.871, P<0.05). With the third-quartile FIB(3.70 g/L)as the cut-off value, the optimal cut-off point of the DM course was 9.5 years as calculated by receiver operating characteristic(ROC)curve analysis of DM duration and hyperfibrinogenemia. Conclusions:The FIB level is positively correlated with DM duration in elderly patients with T2DM.

OBJECTIVE: To investigate the effect of inverse ratio ventilation (IRV) combined with positive end-expiratory pressure (PEEP) in infants undergoing thoracoscopic surgery with single lung ventilation (OLV) for lung cystadenomas. METHODS: A total of 66 infants undergoing thoracoscopic surgery with OLV for lung cystadenomas in our hospital from February, 2018 to February, 2019 were randomized into conventional ventilation groups (group N, =33) and inverse ventilation group (group R, =33). Hemodynamics and respiratory parameters of the infants were recorded and arterial blood gas analysis was performed at 15 min after two lung ventilation (TLV) (T), OLV30 min (T), OLV60 min (T), and 15 min after recovery of TLV (T). Bronchoalveolar lavage fluid was collected before and after surgery to detect the expression level of advanced glycation end product receptor (RAGE). RESULTS: Sixty-three infants were finally included in this study. At T and T, Cdyn, PaO and OI in group R were significantly higher ( < 0.05) and Ppeak, PaCO and PA-aO were significantly lower than those in group N ( < 0.05). There was no significant difference in HR or MAP between the two groups at T and T ( > 0.05). The level of RAGE significantly increased after the surgery in both groups ( < 0.05), and was significantly lower in R group than in N group ( < 0.05). CONCLUSIONS In infants undergoing thoracoscopic surgery with OLV for pulmonary cystadenoma, appropriate IRV combined with PEEP does not affect hemodynamic stability and can increases pulmonary compliance, reduce the peak pressure, and improve oxygenation to provide pulmonary protection.

Objective:To analyze the relationship between plasma fibrinogen(FIB) within normal range and microalbuminuria in elderly patients with type 2 diabetes mellitus.Methods:A total of 869 elderly subjects with type 2 diabetes mellitus admitted to the Department of Endocrinology of Shanghai Fifth People′s Hospital from October 2012 to October 2014 were included in the study. The patients were divided into four groups based on the quartile level of FIB: Q1 group(<2.42 g/L), Q2 group(2.42-2.89 g/L), Q3 group(2.90-3.61 g/L), and Q4 group(≥3.62 g/L). The relationship between FIB and urinary albumin/creatinine ratio(UACR) was analyzed.Results:With the increasing of FIB, the level of UACR was significantly elevated( P<0.05). Pearson correlation analysis showed that FIB was positively associated with age, duration of diabetes, creatinine(Cr) and UACR in men and women( P<0.01). Multiple regression analysis showed that FIB was an independent factor of UACR( P<0.01). Logistic regression analysis showed that the risks of microalbuminuria and macroalbuminuria were respectively 4.536 folds(95% CI 2.516-8.175, P<0.01) and 13.314 folds(95% CI 2.925-60.612, P<0.01) in Q4 group, and 2.177 folds(95% CI 1.273-3.724, P<0.01) and 4.098 folds(95% CI 1.101-19.226, P<0.05) in Q3 group as compared with Q1 group after adjused by following factors: gender, age, duration of diabetes, body mass index(BMI), systolic blood pressure(SBP), diastolic blood pressure(DBP), fasting plasma glucose(FPG), HbA 1C, total cholesterol(TC), triglyceride(TG), low density lipoprotein-cholesterol(LDL-C), Cr, alanine aminotransferase(ALT), as well as smoking and drinking behavior. Based on the cut off values to UACR 30 mg/g and 300 mg/g, the receiver operating characteristic curve(ROC) was used to evaluate the value of FIB for UACR. The optimal cut-off value of FIB was 3.18 g/L and 3.22 g/L respectively. Conclusions:Plasma FIB was closely associated with microalbuminuria in elderly patients with type 2 diabetes mellitus, which may be considered as one of the predictors for diabetic nephropathy.

Purpose: This retrospective study aimed to evaluate the distribution pattern and prognostic value of 21-gene recurrence score (RS) in Chinese patients with mucinous breast cancer (MC) and compared with infiltrating ductal carcinoma (IDC). Materials and Methods: Patients diagnosed with MC or IDC from January 2010 to January 2017 were retrospectively recruited. Reverse transcriptase–polymerase chain reaction assay of 21 genes was conducted to calculate the RS. Univariate and multivariate analyses were performed to assess the association between RS and clinicopathological factors. Survival outcomes including disease-free survival (DFS) and overall survival (OS) were estimated by Kaplan-Meier method and compared by log-rank test. Results: The MC cohort included 128 patients and the IDC cohort included 707 patients. The proportions of patients with a low (RS < 18), intermediate (18-30), or high risk (RS > 30) were 32.0%, 48.4%, and 19.5% in MC cohort, and 26.9%, 46.8% and 26.3% in IDC cohort. The distribution of RS varied significantly according to different Ki-67 index and molecular subtype in both cohorts. Moreover, the receipt of chemotherapy was associated with RS in both cohorts. Among patients with MC, tumor stage was related to the DFS (p=0.040). No significant differences in DFS and OS were found among MC patients in different RS risk groups (OS, p=0.695; DFS, p=0.926). Conclusion RS was significantly related to Ki-67 index and molecular subtypes in MC patients, which is similar in IDC patients. However, RS was not able to predict DFS and OS in patients with MC.

PURPOSE: Recent data have shown that the expression levels of long noncoding RNAs (lncRNAs) are associated with tamoxifen sensitivity in estrogen receptor (ER)-positive breast cancer. Herein, we constructed an lncRNA-based model to predict disease outcomes of ER-positive breast cancer patients treated with tamoxifen. METHODS: LncRNA expression information was acquired from Gene Expression Omnibus by re-mapping pre-existing microarrays of patients with ER-positive breast cancer treated with tamoxifen. The distant metastasis-free survival (DMFS) predictive signature was subsequently built based on a Cox proportional hazard regression model in discover cohort patients, which was further evaluated in another independent validation dataset. RESULTS: Six lncRNAs were found to be associated with DMFS in the discover cohort, which were used to construct a tamoxifen efficacy-related lncRNA signature (TLS). There were 133 and 362 patients with TLS high- and low-risk signatures in the discover cohort. Both univariate and multivariate analysis demonstrated that TLS was associated with DMFS. TLS high-risk patients had worse outcomes than low-risk patients, with a hazard ratio of 4.04 (95% confidence interval, 2.83–5.77; p < 0.001). Both subgroup analysis and receiver operating characteristic analysis indicated that TLS performed better in lymph node-negative, luminal B, 21-gene recurrence score high-risk, and 70-gene prognosis signature high-risk patients. Moreover, in a comparison of the 21-gene recurrence score and 70-gene prognosis signature, TLS showed a similar area under receiver operating characteristic curve in all patients. Gene Set Enrichment Analysis indicated that TLS high-risk patients showed different gene expression patterns related to the cell cycle and nucleotide metabolism from those of low-risk patients. CONCLUSION: This six-lncRNA signature was associated with disease outcome in ER-positive breast cancer patients treated with tamoxifen, which is comparable to previous messenger RNA signatures and requires further clinical evaluation.

OBJECTIVETo explore the safety and efficacy of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in preventing chemotherapy-induced neutropenia in patients with breast cancer and non-small cell lung cancer (NSCLC), and to provide the basis for clinical application.

METHODSAccording to the principle of open-label, randomized, parallel-group controlled clinical trial, all patients were randomized by 1∶1∶1 into three groups to receive PEG-rhG-CSF 100 μg/kg, PEG-rhG-CSF 6 mg, or rhG-CSF 5 μg/kg, respectively. The patients with breast cancer received two chemotherapy cycles, and the NSCLC patients received 1-2 cycles of chemotherapy according to their condition. All patients were treated with the combination chemotherapy of TAC (docetaxel+ epirubicin+ cyclophosphamide) or TA (docetaxel+ epirubicin), or the chemotherapy of docetaxel combined with carboplatin, with a 21 day cycle.

RESULTSThe duration of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg and PEG-rhG-CSF 6 mg groups were similar with that in the rhG-CSF 5 μg/kg group (P>0.05 for all). The incidence rate of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group, and G-CSF 5 μg/kg group were 69.7%, 68.4%, and 69.5%, respectively, with a non-significant difference among the three groups (P=0.963). The incidence rate of febrile neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg/kg group were 6.1%, 6.4%, and 5.5%, respectively, showing no significant difference among them (P=0.935). The incidence rate of adverse events in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg / kg group were 6.7%, 4.1%, and 5.5%, respectively, showing a non-significant difference among them (P=0.581).

CONCLUSIONSIn patients with breast cancer and non-small cell lung cancer (NSCLC) undergoing TAC/TA chemotherapy, a single 100 μg/kg injection or a single fixed 6 mg dose of PEG-rhG-CSF at 48 hours after chemotherapy show definite therapeutic effect with a low incidence of adverse events and mild adverse reactions. Compared with the continuous daily injection of rhG-CSF 5 μg/kg/d, a single 100 μg/kg injection or a single fixed 6 mg dose of PEG-rhG-CSF has similar effect and is more advantageous in preventing chemotherapy-induced neutropenia.

This study examined the value of volume rendering (VR) interpretation in assessing the growth of pulmonary nodular ground-glass opacity (nGGO). A total of 47 nGGOs (average size, 9.5 mm; range, 5.7-20.6 mm) were observed by CT scanning at different time under identical parameter settings. The growth of nGGO was analyzed by three radiologists by comparing the thin slice (TS) CT images of initial and repeat scans with side-by-side cine mode. One week later synchronized VR images of the two scans were compared by side-by-side cine mode to evaluate the nGGO growth. The nodule growth was rated on a 5-degree scale: notable growth, slight growth, dubious growth, stagnant growth, shrinkage. Growth standard was defined as: Density increase ≥ 30 HU and (or) diameter increase (by 20% in nodules ≥10 mm, 30% in nodules of 5-9 mm). Receiver operating characteristic (ROC) was performed. The results showed that 32 nGGOs met the growth criteria (29 nGGOs showed an increase in density; 1 nGGO showed an increase in diameter; 2 nGGOs showed an increase in both diameter and density). Area under ROC curve revealed that the performance with VR interpretation was better than that with TS interpretation (P<0.01, P<0.05 and P<0.05 for observers A, B and C respectively). Consistency between different observers was excellent with both VR interpretation (κ=0.89 for observers A&C, A&B, B&C) and TS interpretation (κ=0.71 for A&B, κ=0.68 for A&C, κ= 0.74 for B&C), but time spending was less with VR interpretation than with TS interpretation (P<0.0001, P<0.0001 and P<0.05 for observers A, B and C, respectively). It was concluded that VR is a useful technique for evaluating the growth of nGGO.
