Objective:To investigate the predictive value of estimated renal perfusion pressure (eRPP) for acute kidney injury (AKI) in severe multiple trauma patients.Methods:Severe multiple trauma patients were collected based on the inclusion criteria and exclusion criteria from the Trauma Center, the Third Xiangya Hospital, Central South University. Subsequently, patients were divided into the AKI group and non-AKI group according to the occurrence of AKI during 72 h admission to hospital. Further clinical information, ISS score, SOFA score, APACHE Ⅱ score, mean arterial pressure (MAP), central venous pressure (CVP) and intra-abdominal pressure (IAP) were collected, and eRPP were calculated. Additionally, the differences of parameters in the AKI group and non-AKI group were analyzed and logistic regression analysis was performed to identify the independent predicted risk factors for AKI. Finally, ROC curve was conducted to identify specificity, sensibility and best cut-off point.Results:A total of 173 severe multiple trauma patients were finally analyzed. Compared with the non-AKI group, the serum albumin [(32.21±5.20)g/L vs. (34.83±4.20)g/L, P =0.001] and 24 h urine output [(711.90±241.38)mL vs. (1 101.21±509.86)mL, P =0.001] were significantly lower and serum lactate [(2.80±0.96)mmol/L vs. (1.89±0.63)mmol/L, P<0.001], ISS score [(29.05±5.91) vs. (22.17±4.02), P <0.001], APACHEⅡ score [(38.84±21.47) vs. (31.45±18.24), P <0.001] and SOFA score [(5.26±2.08) vs. (3.14±1.34), P <0.001], in-hospital mortality (9.52% vs. 2.29%, P=0.038), and ICU stay [(8.43±6.46)d vs. (6.42±3.78) d, P =0.01) were significantly higher in the AKI group. Moreover, 6, 12 and 24 h of CVP and eRPP after admission were associated with the incidence of AKI. Logistic regression analysis showed that 24 h urine output, CVP and eRPP were the independent predictive factors (P <0.05) and 24 h of eRPP after admission applied a better predictive value of the incidence in AKI. Conclusions:24 h of eRPP might be the most suitable independent predictive factor for AKI in severe multiple trauma patients.

Purpose To evaluate the effect of PCSK9 gene knockout on myocardial function in obese mice via ultrasound strain technology,and to discuss the related mechanisms.Materials and Methods Twenty six-week-old wild-type C57BL/6 male mice were selected and randomly divided into a normal group(n=10)and an obese group(n=10).Additionally,ten six-week-old PCSK9-/-C57BL/6 male mice were selected as the PCSK9-/-group.Mice in the obese group and PCSK9-/-group were fed with high-fat feed to create models,while those in the normal group were fed with regular feed.After 12 weeks,mice that were successfully modeled were selected from the obese group and PCSK9-/-group.Then,the three groups of mice were subjected to cardiac ultrasound,transmission electron microscopy and immunofluorescence staining to observe relevant indicators.Results The interventricular septal end-diastolic thickness of mice in obese group,normal group,and PCSK9-/-group were(0.98±0.13)mm,(0.77±0.07)mm,(0.78±0.13)mm,respectively,with statistically significant difference(F=5.10,P=0.02).The obese group was thicker than the normal group(t=2.73,P＜0.05),while the PCSK9-/-group was thinner than the obese group(t=-2.92,P＜0.05).There were statistically significant differences in global longitudinal strain and global circumferential strain of the left ventricle among the three groups(F=7.44,15.40,P＜0.05),with the obese group showing a decrease in global longitudinal strain and global circumferential strain compared to the normal group(t=3.79,5.50,P＜0.05).The PCSK9-/-group showed an increase in global longitudinal strain and global circumferential strain compared to the obese group(t=-2.53,-3.37,P＜0.05).Electron microscopy and immunofluorescence results showed that the myocardial ultrastructure of the obese group was damaged,and the expression of NLRP3 and Caspase-1 were higher than that of the normal group(t=12.53,-4.73,P＜0.05),the myocardial ultrastructure damage in the PCSK9-/-group was significantly improved,the expression of NLRP3 and Caspase-1 were lower than that in the obese group(t=-6.23,2.05,P＜0.05).Conclusion Ultrasound strain can more sensitively detect changes in myocardial function in obese mice with PCSK9 gene knockout compared with conventional cardiac ultrasound parameters.Knockout of the PCSK9 gene may improve myocardial function in obese mice by inhibiting the expression of NLRP3 and Caspase-1.

Immunosuppressants are the most commonly used therapeutic means to reduce organ transplantation rejection and improve short-term clinical outcomes of patients after transplantation. However, systemic use of immunosuppressants increases the risk of opportunistic infections and the incidence of malignancies. Therefore, the efficient targeted delivery of immunosuppressants to target organs is particularly important. Lymph nodes are the main sites of transplant rejection activation. In recent years, drug delivery systems targeting lymph nodes have played an increasingly important role in the treatment of organ transplant rejection. This review briefly introduces the mechanism of action of lymph nodes in transplant rejection, and focuses on the construction of lymph node targeted drug delivery system and its application in transplant rejection, aiming to apply it in the treatment of transplant rejection toimprove patient outcomes.

To explore the role of P53, pairing box gene 8 antibody (PAX8), and calcium omentum protein (Calretinin) in the origin of epithelial ovarian cancer.
 Methods: A total of 63 tissue samples of ovarian tumor and fallopian tubes were collected. Immunohistochemistry methods were used to analyze the expression of P53, PAX8, and Calretinin. The relationship between these protein levels and the classification of ovarian tumors was evaluated.
 Results: In epithelial ovarian cancer, the P53 or PAX8 was correlated with the occurrence of high-grade carcinoma, while the calretinin was correlated with the occurrence of low-grade carcinoma (P<0.05). The combination of PAX8 with Calretinin was correlated with the grade of ovarian tumor (P<0.05). The combination of P53 with Calretinin was correlated with the grade of tumor (P<0.05). The combination of P53 with PAX8 was correlated with the grade of tumor (P<0.05). The expression of P53 in fallopian tubes was correlated with the malignant degree of epithelial ovarian cancer (P<0.05). The degree of fallopian tube lesions in patients with ovarian cancer was correlated with epithelial ovarian cancer. The malignant lesions of tubal epithelium was correlated with high-grade carcinoma, while the normal or atypical hyperplasia of tubal epithelium was correlated with low-grade carcinoma (P<0.05).
 Conclusion: P53 and Calretinin combined with PAX8 show a synergistic effect on the differentiation of epithelial ovarian cancer grade. The morphology of HE and the expression of TP53 in the fallopian tube epithelium play an auxiliary role in the diagnosis of epithelial ovarian cancer.
