Objective To explore the relationship between coping styles and childhood abuse in adult patients with depression . Methods A case‐control study was conducted between 80 adult patients with depression and 80 health controls .In general ques‐tionnaire was designed to collect the demo‐graphic information ,Childhood Trauma Questionnaire‐28 Item Short Form (CTQ‐SF) was used to assess childhood trauma and Trait Coping Styles Questionnaire (TCSQ) was assigned to evaluate coping styles .T test , Mann‐Whitney U test ,Spearman Bivariate correlations and Multiple linear regression were employed to explore the characteristics of the major depressive patients′coping styles and the association between childhood abuse .Results (1) The patients with depres‐sion had both statistically significantly higher scores on negative coping style (t=9 .13 ,P<0 .01) and lower scores on positive cop‐ing style (t= -12 .01 ,P<0 .01)than the controls with childhood abuse .The patients with childhood abuse had both statistically significantly higher scores on negative coping style(Z= -6 .134 ,P<0 .01) and lower scores on positive coping style(Z= -5 .452 , P<0 .01) than the controls with childhood abuse .Inside the group of patients with depression ,the patients who had childhood a‐buse gained significantly higher scores in negative coping style than the others who had no early trauma (Z= -2 .159 ,P<0 .05) , however ,no conspicuous differences were found on the positive coping style scores .(2)The childhood abuse was both significantly positive correlated with the passive coping and negative related to the active coping (r=0 .562 ,P<0 .01;r= -0 .333 ,P<0 .05)a‐mong the patients of depression .(3)The total degree of abuse and physical abuse had significant prediction function of 34 .4% (P<0 .01)on the patients′ negative coping .Conclusion The coping styles of patients with depression were prone to be influenced by childhood abuse remarkably ,more severe abuse ,especially with the physical abuse ,more negative the coping styles were .

Objective To investigate the effect of dipeptidyl peptidase-4 (DPP-4) inhibitor on lipopolysaccharide (LPS)-induced changes in the mass and function of pancreatic β-cells.Methods RINm cells were cultured and treated with LPS alone or combined with different concentrations of sitagliptin for 24 h.The proliferation of RINm cells was detected by CCK-8 assay.Apoptotic rate was determined by Annexin V-fluorescein isothiocyanate (FITC)/propidium iodide flow cytometry.Insulin secretion was measured by enzyme-linked immunosorbent assay.The expression of IL-6 mRNA was displayed by RT-PCR.Results LPS significantly stimulated the proliferation of RINm cells (0.89 ± 0.04 vs 1.14 ± 0.08,P＜0.01),while LPS+sitagliptin showed no significant difference compared with LPS group.The cell apoptotic rate in LPS + 10-1 mmol/L sitagliptin group was significantly lower than that in LPS group.There were no significant differences in basal insulin secretion among all groups,but after the high/low glucose stimulation,LPS increased insulin secretion as compared with the control.The IL-6 mRNA expression in LPS+sitagliptin group was significantly lower than that in LPS group (0.77 ± 0.33 vs 1.30 ± 0.41,P =0.006).Conclusions DPP-4 inhibitor has no influence on LPS-induced proliferation of pancreatic β-cell,but it can inhibit LPS-induced apoptosis and insulin secretion,and IL-6 may be involved in the process.

Objective The three-dimensional reconstructed images of maximum intensity projection (MIP) for membranous labyrinth and internal auditory meatus in Chinese adults were observed and measured in order to provide anatomic basis for otolosurgery and nerosurgery. Methods Thirty inner ears of 15 volunteers were scanned by using a circular temporal coil and three-dimension fast spin echo sequence with a 1^5T GE-signal MRI scanner. All original images were transferred to MRI workstation and all the structures of inner ear were reconstructed, rotated from various angles and measured by using maximum intensity projection. All the data were analyzed using SPSS 10.0 software. Results Anatomic structures of membranous labyrinth and internal auditory meatus were well demonstrated in three-dimensional reconstructed images of MIP in all volunteers. All three semicircular ducts, utricle, saccule, cochlear duct and internal auditory meatus produced high intensity signal. The results of measurement were statistically in significant.Conclusion Three-dimensional reconstruction of MlP might document, lively, stereoscopically and directly, the minute structures of membranous labyrinth and internal auditory meatus. We provide the basic data for the establishment of the MRI measurement criterion of inner ear.

AIM: To explore the effect and possible mechanism of type 2 innate lymphoid cell (ILC2) on the development of chronic renal failure (CRF).METHODS: The patients with chronic renal failure (n=36) in the Fist Affiliated Hospital of Sun Yat-sen University from March 2016 to December 2016 were selected, and 32 healthy persons in the same period were enrolled in the study for control.The proportion of ILC2 in the PBMC of CRF patients and healthy controls was detected by flow cytometry, IL-13 concentration in the plasma was measured by ELISA.The isolated PBMCs from the patients and healthy persons were divided into 3 groups (control group, cytokine group, intervention group) and cultured in vitro for 3 days, respespestively, then IL-13 concentration was measured by ELISA.The protein levels of phosphorylated signal transducers and activators of transcription 6 (p-STAT6) in the PBMC of healthy controls before stimulation and after stimulation for 15 min, 30 min, 1 h, 2 h were determined by Western blot.RESULTS: The proportion of ILC2 in the PBMC and the plasma IL-13 concentration of CRF patients was higher than that in the healthy controls (P<0.05).In the culture supernatant in vitro, IL-13 concentration in the 3 subgroups of CRF patients (control group, cytokine group, intervention group) were all higher than that in the healthy controls (P<0.05), both the 2 groups showed a trend that the active IL-13 concentration in cytokine group was higher than that in control group, and that in intervention group was lower than that in cytokine group.The protein levels of p-STAT6 in cytokine stimulated-PBMC with a time dependent manner.CONCLUSION: The percentage of ILC2 in the PBMC is elevated in CRF patients.Furthermore, the ILC2 secret large amount of IL-13 to mediate the polarization of Th2 cells to regulate immunity through activating p-STAT6.

Objective To explore the predictive value of contrast-enhanced echocardiography com-bined with serum levels of CD137 and insulin-like growth factor binding protein 6(IGFBP-6)for cardiovascular adverse events(MACE)in elderly patients with stable coronary heart disease(CHD)after percutaneous coronary intervention(PCI).Methods A total of 108 elderly patients with stable CHD(CHD group)who visited Department of Cardiology of Changsha First Hospital from March 2020 to March 2022 were recruited in this study.They were grouped into a non-MACE group(81 cases)and a MACE group(27 cases)according to whether MACE occurred after PCI.Another 100 healthy individuals who taking physical examination during the same period served as control group.Their serum CD137 and IGFBP-6 levels were detected,and the contrast agent filling speed(β value)and maximum number of microbubbles(A value)were calculated based on the results of contrast-enhanced echocardiography.Their general clinical data were col-lected.ROC curve analysis and multivariate logistic regression analysis were used to analyze the data.Results The serum levels of CD137 and IGFBP-6 were significantly higher,while the β value and A value were obviously lower in the CHD group than the control group(P＜0.01).And the serum levels were notably higher,and the β value and A value were remarkably lower in the MACE group than the non-MACE group(P＜0.01).The AUC of cardiac ultrasound parameters βvalue and A value combined with serum CD137 and IGFBP-6 to predict MACE after PCI in CHD patients was 0.930,which was significantly higher than the AUC value of every single indicator(P＜0.01).β value,A value,CD137 and IGFBP-6 levels were all risk factors for the occurrence of MACE in CHD patients after PCI(P＜0.01).Conclusion Contrast-enhanced echocardiography,serum CD137 and IGFBP-6 levels have certain predictive value for MACE in elderly CHD patients after PCI,and combined detection has higher predictive value.

Objective:To explore the high-risk factors for parenteral nutrition associated cholestasis（PNAC）in extremely/ultra-low birth weight infants，and establish a risk Alignment Diagram prediction model.Methods:We retrospectivly analyzed the clinical data of hospitalized extremely/ultra-low birth weight infants admitted to Neonatology Department at Quanzhou Children's Hospital from January 2019 to December 2020，using multivariate Logistic regression analysis to screen for independent risk factors for the occurrence of PNAC.An Alignment Diagram model prediction model for PNAC was constructed by using R software，and the performance of the model was evaluated through receiver operating characteristic curves.Results:A total of 203 extremely/ultra-low birth weight infants were included，with a median gestational age of 29.14（28.00，30.86）weeks and a median birth weight of 1　170（1　000,1　300）g.Among them，26（12.81%）cases developed PNAC.Multivariate Logistic regression analysis showed that the duration of parenteral nutrition（ OR=1.015 ，95% CI 1.003-1.034），the cumulative amount of glucose（ OR=1.014 ，95% CI 1.001-1.028），small for gestational age（ OR=3.455 ，95% CI 1.127-10.589），and neonatal sepsis（ OR=3.142 ，95% CI 1.039-9.503）were independent risk factors for PNAC（ P＜0.05）；The four independent risk factors mentioned above were introduced into R software to construct an Alignment Diagram model，the area under the receiver operating characteristic curve was 0.835（95% CI 0.842-0.731），and the results of the Hosmer Limeshow goodness of fit test show that：χ 2=5.34，degree of freedom=8， P=0.72.A calibration curve indicated good consistency between the predicted probability of the model and the actual occurrence rate，with good accuracy. Conclusion:The Alignment Diagram model constructed based on four independent risk factors of the duration of parenteral nutrition，glucose accumulation，small for gestational age infants，and neonatal sepsis exhibits high predictive ability，and is expected to provide an intuitive and convenient visualization tool for preventing or reducing the occurrence of PNAC in extremely/ultra-low birth weight infants

OBJECTIVES: To determine the association between glycosylated hemoglobin (HbA1c) and ambulatory blood pressure or heart rate in hypertensive patients. METHODS: A total of 585 patients, who performed ambulatory blood pressure monitoring (ABPM) from September 2018 to April 2019 in Xiangya Hospital, Central South University, were enrolled and assigned into 2 groups (470 in a hypertensive group and 115 in a normal group). HbA1c levels were compared. According to the HbA1c level, the hypertensive group was divided into 2 subgroups: A high HbA1c group (HbA1c≥6.1%, RESULTS: The hypertensive group had higher HbA1c level than the normal group [(6.1±1.3)% vs (5.1±1.7)%, CONCLUSIONS In hypertensive patients, HbA1c is positively correlated with ambulate blood pressure, blood pressure load, and heart rate, and it has no correlation with blood pressure variability, heart rate variability, or morning blood pressure.
