Objective:To investigate the diagnostic value of mitochondrial associated protein fumarylacetoacetate domain containing protein 1 (FAHD1) and growth differentiation factor-15 (GDF-15) in sepsis.Methods:Based on the database of the whole process of sepsis early warning, diagnosis and treatment management, which was established on the study of sepsis early warning and standardized diagnosis and treatment system, adult patients with suspected infection admitted to the department of critical care medicine of Zhejiang Hospital, Second Affiliated Hospital of Zhejiang University, the First Affiliated Hospital of Sun Yat-Sen University, West China Hospital of Sichuan University, Ningbo First Hospital from May 2014 to October 2015 were enrolled. The basic vital signs, and the main blood routine results, liver and kidney function, blood gas, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) and sequential organ failure assessment (SOFA) score at the time of diagnosis of patients with or without sepsis were analyzed. The preserved serum samples were taken, the levels of procalcitonin (PCT), C-reactive protein (CRP) were detected by electrochemiluminescence method, immunoturbidimetry respectively, and FAHD1 and GDF-15 were detected by enzyme linked immunosorbent assay (ELISA). Univariate and multivariate Logistic regression were used to analyze the risk factors for sepsis diagnose. The indexes' diagnostic efficacy in sepsis were analyzed by receiver operating characteristics curve (ROC curve).Results:A total of 132 patients were enrolled, including 76 cases of sepsis and 56 cases of non-sepsis. Compared with the non-sepsis group, the heart rate in the sepsis group was increased (bpm: 116.4±17.8 vs. 97.4±19.1), while the mean arterial pressure (MAP), platelet count (PLT), arterial partial pressure of oxygen (PaO 2) were significantly decreased [MAP (mmHg, 1 mmHg = 0.133 kPa): 65.8±9.7 vs. 74.7±10.3, PLT (×10 9/L): 120 (69, 204) vs. 163 (117, 239), PaO 2 (mmHg): 83.0 (66.6, 108.0) vs. 108.0 (84.4, 130.0), all P < 0.05], direct bilirubin (DBil), serum creatinine (SCr), lactic acid (Lac), APACHEⅡ score and SOFA score were significantly increased [DBil (μmol/L): 13.00 (5.55, 55.31) vs. 6.20 (2.20, 21.90), SCr (μmol/L): 118.00 (70.00, 191.73) vs. 77.20 (59.65, 110.86), Lac (mmol/L): 2.90 (1.50, 4.10) vs. 1.90 (1.20, 2.80), APACHEⅡ score: 20.0 (16.0, 25.0) vs. 16.0 (10.0, 21.0), SOFA score: 12.0 (8.0, 16.0) vs. 8.0 (5.0, 13.0), all P < 0.05]. In addition, the serum levels of FAHD1, GDF-15, PCT and CRP in sepsis group were significantly higher than those in non-sepsis group [FAHD1 (μg/L): 3.96 (2.25, 5.92) vs. 2.47 (1.03, 3.54), GDF-15 (μg/L): 8.46 (4.37, 19.68) vs. 4.32 (1.74, 10.39), PCT (μg/L): 3.79 (1.37, 11.32) vs. 0.42 (0.12, 2.14), CRP (mg/L): 154.43 (61.33, 283.20) vs. 65.95 (28.15, 144.69), all P < 0.01]. Multivariate Logistic regression showed that serum FAHD1 [odds ratio ( OR) = 1.135, 95% confidence interval (95% CI) was 1.045-1.234], GDF-15 ( OR = 1.090, 95% CI was 1.029-1.155) and CRP ( OR = 1.007, 95% CI was 1.002-1.011) were risk factors for sepsis (all P < 0.05). ROC curve analysis of sepsis showed that the areas under ROC curve (AUC) of serum mitochondrial associated proteins FAHD1 and GDF-15 were 0.727 (95% CI was 0.641-0.802) and 0.677 (95% CI was 0.588-0.757), respectively; and the AUC of classical infection indexes PCT and CRP were 0.767 (95% CI was 0.683-0.837) and 0.680 (95% CI was 0.59-0.760), respectively. There was no significant difference between the AUC of mitochondrial associated proteins and classical infection indexes. The combination of FAHD1, GDF-15, PCT and CRP had the largest AUC, which was 0.809 (95% CI was 0.730-0.874), and the sensitivity was 75.00%, and the specificity was 80.00%. Conclusion:Mitochondrial associated protein FAHD1 and GDF-15 are associated with sepsis, and the diagnostic efficiency is improved when combined with PCT and CRP, which might provide experimental basis for screening diagnostic markers of sepsis.

Objective To investigate the clinical efficacy of combined acupuncture and medicine plus ultrashort wave diathermy in treating post-stroke complicated urinary tract infection.Methods One hundred and twenty patients with post-stroke complicated urinary tract infection were randomly allocated to groups A, B and C, 40 cases each. Group A received acupuncture, ultrashort wave diathermy and treatment with anti-infective drugs; group B, ultrashort wave diathermy and treatment with anti-infective drugs; group C, treatment with anti-infective drugs alone. The clinical therapeutic effects and the recurrence rates were compared between the three groups.Results The total efficacy rate was 92.5% in group A, 90.0% in group B and 72.5% in group C. There was a statistically significant difference in the total efficacy rate between group A or B and group C (P<0.05). The recurrence rate was 8.1% in group A, 27.8% in group B and 31.0% in group C. There was a statistically significant difference in the recurrence rate between group A and group B or C (P<0.05).Conclusion Combined use of acupuncture and medicine plus ultrashort wave diathermy is an effective way to treat post-stroke complicated urinary tract infection.

More translocations of STAT3 to the nucleus were seen.Conclusion JAK-STAT signal transduction pathway was involved in the pathological processes in the retinal after transection of the optic nerve.

Objective To investigate the efficacy of transplantation of induced bone marrow mesenchymal stem cells(MSCs)via various route for treatment of chronic liver injury.Methods MSCs were isolated and expanded by density gradient centrifugation combined with adherent culture.MSCs were induced to differentiate into hepatocyte-like cells in vitro.The markers of hepatocyte lineage were examined by RT-PCR and immunocytochemistry.The changes of ultramicrostructure of MSCs were observed by transmission electron microscope.One hundred and fourteen Wistar rats were treated with mixture of 40%CCl4 and peanut oil to establish chronic liver injury model and another 6 rats were served as control.Twelve rats in model group were died within 8 weeks,and the rest rats were divided into portal vein,spleen and tail vein transplantation groups.The rats were transplanted with DAPI-labelled MSCs which were induced for 14 days.The distribution of the DAPI-labelled cells were observed by fluorescence microscopy.The liver function and pathology were examined.Results AFP mRNA expression were detected at 7th and 14th day after induction,expressions of ALB mRNA,CK18 and hepatocyte antigen were found at 14th and 2lth day.The ultrastructure examination revealed that MSCs were enlarged with a lot of endoplasmic reticulum,mitochondrion,lysosome and glycogen granule.DAPI labelled cells were found in the spleen and liver transplantion groups.The pathological changes of liver were alleviated in all treated groups,especially in intraspleenic transplantion group(P＜0.05).Conclusions Induced bone marrow MSCs can ameliorate liver function of chronic hepatic injury after transplantation.The intraspleenic transplantation is better than others.

Prone position ventilation has become an important part of lung protective ventilation in acute respiratory distress syndrome (ARDS) patients. Timely and appropriate implementation can improve the mortality of such patients. The same is true for patients with critical coronavirus disease 2019 (COVID-19) patients, but safety assessment, control of implementation details and prevention of complications still need to be further standardized during the practical procedure of prone position ventilation. The purpose of this paper is to explain the specific requirements and key points of prone position ventilation in critical COVID-19 patients, in order to promote the application of prone position ventilation in the treatment of patients with critical COVID-19 and reduce the occurrence of related complications.
