ABSTRACT
Objective:To investigate the prognosis value of the Child-Turcotte-Pugh (CTP), pediatrics end-stage liver disease/model for end-stage liver disease(PELD/MELD) and sequential organ failure assessment (SOFA) scores in pediatric acute liver failure (PALF) at 28 th day. Methods:Fifty-four PALF patients admitted in the Pediatric Intensive Care Unit (PICU) and Infection Department of Pediatrics, Qingdao Women′s and Children′s Hospital from June 1, 2012 to June 1, 2019 were included in the study.According to the survival of PALF patients on the 28 th day, they were divided into the survival group (28 cases) and the death group (26 cases). Baseline characte-ristics and laboratory examination data of PALF patients in both groups were collected and compared.Receiver operating characteristic (ROC) curve was used to evaluate the prognostic value of CTP, PELD/MELD and SOFA scores in PALF. Results:The mortality rate of 54 PALF patients was 48.1%.Compared with the survival group, PALF patients in the death group were significantly younger than those in survival group [11.0(3.8-39.0) months vs.14.5(7.3-84.0) months]( Z=-2.145, P=0.020). In addition, CTP, PELD/MELD and SOFA scores were significantly higher in the death group than those in survival group [14.0(11.7-15.0) vs.9.0(7.0-10.0), 32.0(29.0-36.0) vs.25.0(22.0-26.0), 13.0(11.0-16.0) vs.6.0(4.0-7.0)]( Z=-5.095, -4.894, -5.502, all P<0.05). Serum lactate level, blood ammonia level, total bilirubin, direct bilirubin and international normalized ratio were significantly higher in the death group than those in survival group [3.4(2.1-5.3) mmol/L vs.1.5(0.8-2.3) mmol/L, 69.5(46.9-102.9) μmol/L vs.41.7(27.3-50.3) μmol/L, 173.0(97.0-237.2) μmol/L vs.71.9(62.0-136.9) μmol/L, 132.3(53.6-206.2)μmol/L vs.59.3(62.0-99.7) μmol/L, 2.6(1.8-3.5) vs.1.7(1.5-1.9)]( Z=-4.027, -3.220, -2.649, -2.648, -3.807, all P<0.05). Prothrombin time (PT) was significantly prolonged in the death group than that of survival group [27.5(19.2-41.9)s vs.17.8(16.9-22.2)s]( Z=-3.489, P<0.05). Compared with those of survival group, serum albumin, alanine transaminase (ALT) and alpha fetoprotein (AFP) levels were significantly lower in the death group [(30.9±1.0) g/L vs.(33.6±0.9) g/L, 379.2(163.3-880.3) U/L vs.962.5(457.0-1 657.3) U/L, 7.5(0.7-115.8) μg/L vs.22.1(7.9-91.3) μg/L]( t=2.049, Z=-2.510, -2.342, respectively, all P<0.05). The incidence of alimentary tract hemorrhage was significantly higher in the death group than that of survival group (22/26 cases vs.11/28 cases)( χ2=13.340, P<0.05). The cut-off value of CTP, PELD/MELD and SOFA scores in predicting the prognosis of PALF were 11.5, 28.5 and 10.0, respectively.Among the three scoring systems, the specificity and positive predictive value of SOFA scores remained the highest.The sensitivity and specific of a combination of three scoring systems in predicting the prognosis of PALF were 92.3% and 89.3%, respectively, and its Youden index was the highest than that of a single scoring of either CTP, PELD/MELD or SOFA ( Z=2.19, P<0.05). Conclusions:CTP, PELD/MELD and SOFA scores have high predictive value for the short-term prognosis of PALF.The combined detection of the three scoring systems can improve the forecasting efficiency of PALD.
ABSTRACT
Monocarboxylic acid transporter 1 (MCT1) maintains axonal function by transferring lactic acid from oligodendrocytes to axons. Subarachnoid hemorrhage (SAH) induces white matter injury, but the involvement of MCT1 is unclear. In this study, the SAH model of adult male Sprague-Dawley rats was used to explore the role of MCT1 in white matter injury after SAH. At 48 h after SAH, oligodendrocyte MCT1 was significantly reduced, and the exogenous overexpression of MCT1 significantly improved white matter integrity and long-term cognitive function. Motor training after SAH significantly increased the number of ITPR2

Objective:To discuss the incidence rate and influencing factors of postencephalitic epilepsy (PE) in children with viral encephalitis at acute symptomatic seizure(ASS).Methods:The data of 132 children with ASS in the First Affiliated Hospital of Zhengzhou University from September 2013 to July 2018 were retrospectively analyzed, and the patients were divided into PE group (62 cases) and non-PE group (70 cases) according to whether they had PE at final follow-up.The risk factors of PE in children with ASS were analyzed using the multivariate Logistic regre-ssion methods. Results:The incidence of PE in children with ASS was 46.97% (62/132 cases). There were statistically significant differences in terms of psychological and behavioral abnormalities[19.4%(12/62 cases) vs.2.9%(2/70 cases)], repetitive seizures (more than 5 seizures) [67.7%(42/62 cases) vs.17.1%(12/70 cases)], status epilepticus (SE) [30.6%(19/62 cases) vs.11.4%(8/70 cases)], generalized seizures [72.6%(45/62 cases) vs.88.6%(62/70 cases)], endotracheal intubation [21.0%(13/62 cases) vs.2.9%(2/70 cases)], the duration of fever [5.5(3.0, 11.0) d vs.3.0(2.0, 6.0) d], the duration in the intensive care unit (ICU) [13(5, 21) d vs.6(3, 8) d], electroencephalography epileptiform discharges [49.1%(27/55 cases) vs.6.8%(4/59 cases)], presence of subcortical involvement on neuroimaging [37.3%(22/55 cases) vs.20.3%(14/59 cases)] in children with ASS between the PE group and the non-PE group(all P<0.05). The multivariate Logistic regression analysis showed that repetitive seizures (more than 5 seizures) ( OR=5.256, 95% CI: 1.538-17.961, P=0.008), SE( OR=6.003, 95% CI: 1.411-25.539, P=0.015), electroencephalography epileptiform discharges ( OR=36.693, 95% CI: 7.031-191.485, P<0.01) and the duration in ICU ( OR=1.170, 95% CI: 1.058-1.298, P=0.002) were the risk factors for PE in children with ASS. Conclusions:The incidence rate of PE in children with ASS is high.Children with ASS are more likely to develop into PE if they have repetitive seizures (more than 5 seizures), SE, electroencephalography epileptiform discharges, and the longer duration in ICU.
ABSTRACT
The related changes of bone marrow microenvironment (especially mesenchymal stem cells and osteoblasts) would lead to the occurrence of leukemia. Bone morphogenetic protein (BMP) is considered to be the only known morphogenetic factor capable of inducing differentiation of mesenchymal stem cells into osteoblasts, and its role in regulating the occurrence and development of leukemia in the bone marrow microenvironment has been paid more attention. The studies found that acute myeloid leukemia derived-mesenchymal stem cells induced the morphologic transformation and resistance of K562-ADM through BMP. This paper reviews the related research of BMP in order to provide new targets and directions for the research and treatment of leukemia.
ABSTRACT
We reported a case of monochorionic monoamniotic twins discordant for anencephaly diagnosed by second-trimester ultrasonography at the First Affiliated Hospital of Fujian Medical University.Ultrasound at seven weeks of gestation showed only one gestational sac with an embryo inside.Another 12 gestational weeks' ultrasound scan performed at another hospital found one gestational sac and one fetus (crown-rump length was 6.11 cm and nuchal translucency was 0.11 cm) in the upper-middle uterine cavity.The ultrasound examination at 22+6 gestational weeks identified one placenta and two fetuses without obvious diaphragm echo in between.Although no structural abnormality was observed in one fetus,frog-like eyes,absence of skull image and brain tissue echo were presented in the other fetus.The patient was transferred to a higher level hospital and was successfully performed radiofrequency ablation for selective reduction at 23+4 weeks of gestation.At 35 weeks,a premature live boy and an anencephalic stillbirth fetus were born vaginally after premature rupture of membranes.The baby boy was healthy at follow-up at four months old.
ABSTRACT
Objective To study the changes and significance of serum intestinal fatty acid binding protein (IFABP) in children with traumatic brain injury(TBI) complicaled with acute gastrointestinal injury (AGI). Methods A total of 95 children suffering from TBI hospitalized in the PICU of the First Affiliated Hospital of Zhengzhou University from January 2017 to March 2018 were enrolled in the study. According to the modified Glasgow coma score combined with clinical classification criteria for acute closed head injury, the cases were devided into mild(43 cases),moderate (23 cases),and severe(29 cases). Children were gra-ded according to AGI (AGI Ⅰ42 cases,AGI Ⅱ 30 cases,AGI Ⅲ 13 cases,and AGI Ⅳ 10 cases). Thirty healthy children who underwent physical examination at outpatient service were enrolled as the control group. Blood samples were collected at the time of admission and on the 3rd day after admission. Serum IFABP was detected by ELISA,and the differences of serum IFABP concentrations were compared among groups. The correlations between IFABP with TBI classification and AGI grade were analyzed. The receiver operating characteristic (ROC) curve was drawn,and the predictive values of IFABP for the diagnosis of children with TBI complicated with AGI were evaluated. Results On the day of admission,the serum levels of IFABP in mild,moderate and severe brain injury group were significantly higher than that in control group (all P <0. 01). And serum IFABP concentration gradually increased with the increase of brain injury (all P < 0. 01).Serum IFABP levels in children with AGI grade Ⅰto Ⅳ were significantly higher than those in control group (all P < 0. 01). The levels of serum IFABP also increased with the increase of AGI level (all P < 0. 01). The concentration of serum IFABP was positively correlated with the grade of TBI and AGI (rs = 0. 82,P < 0. 01;rs = 0. 70,P < 0. 01). In each group,the levels of serum IFABP on the 3rd day after admission were lower than those on admission (all P < 0. 01). The ROC curve analysis showed that serum IFABP was of high diag-nostic value in children with TBI complicated with AGI,and the area under the ROC curve was 0. 88. When the cutoff value of IFABP was 431. 36 ng/ L,the sensitivity and specificity were 71. 61％ and 90. 00％ ,re-spectively. Conclusion Serum IFABP can be used as a sensitive indicator for the early diagnosis and disease assessment in children with TBI complicated with gastrointestinal dysfunction.

ABSTRACT
Objective To investigate the expressions of TK1 (thymidine kinase 1) in PHC (primary hepatic carcinoma). Methods TK1 and AFP in serum of 33 cases of PHC (primary hepatic carcinoma), 38 cases of hepatic cirrhosis,36 cases of hepatitis and 35 cases of healthy people were detected by means of Western blot—enhanced chemiluminecence and electrochemiluminescence. Results The difference of TK1 level in PHC group indicated significance when compared with that in hepatic cirrhosis group , hepatitis group and control group (U value was 436.4, 352.1, 163.6, respectively, all P 0.05). Kaplan-Meier curve analysis revealed that PHC patients with TK1≤ 2.0 pmol/L had a significantly shortened overall survival when compared with those with TK1 > 2.0 pmol/L (χ2 = 3.954,P < 0.05). Multivariable Cox regression analysis indicated that the level of TK1 and TNM stage were the independent risk factors for patients with PHC (all P <0.05). Conclusions The detection of TK1 has a certain clinical value in the diagnosis, monitoring and evaluation of the prognosis of the PHC.
ABSTRACT
OBJECTIVE@#To explore the effect of general anesthesia combined with epidural anesthesia and patient-controlled epidural analgesia on the incidence of the post-operative cognitive dysfunction (POCD) in elderly patients. @*METHODS@#A total of 100 elderly patients with gastric cancer, who underwent radical gastrectomy in Yan'an People's Hospital from March 2012 to March 2015, were randomly divided into 3 groups: a general anesthesia and patient-controlled intravenous analgesia (PCIA) (Group I, n=35), a general anesthesia combined with epidural anesthesia and PCIA (Group II, n=30), and a general anesthesia combined with epidural anesthesia and patient-controlled epidural analgesia (PCEA) (Group III, n=35). There was no significant difference in age, gender, body mass index (BMI), length of operation, American Society of Anesthesiologists (ASA) grade and Mini-Mental State Examination (MMSE) score (all P>0.05). The cognitive function was assessed at the 1st day before operation and at the 6 h, 12 h, 2 d and 6 d after operation by the Mini-Mental State Examination test (MMSE), and the incidence of POCD was compared among the 3 groups. The mean arterial pressure (MAP), blood glucose, cortisol and tumor necrosis factor α (TNF-α) content during the operation were considered. The dosage of sevoflurane (SEVO) in the operation process and the pain score at the 6, 12 and 24 h after operation were recorded. @*RESULTS@#The incidence of POCD at 6 h was 45.71% in the Group I and 34.28% in the Group II, which were higher than that in the Group III (10.00%). The incidence of POCD at 12 h was 34.29% in the Group I and 28.57% in the Group II, which were higher than that in the Group III (3.33%). The incidence of POCD at the 2 d was 28.57% in the Group I and 17.14% in the Group II, which were higher than that in the Group III (0). The incidence of POCD at 6 d was 17.14% in the Group I and 2.85% in the Group II, which were higher than that in the Group III (0). The blood glucose, cortisol and TNF-α content were consistent with the incidence of POCD, with significant difference (all P<0.05). The amplitude of MAP in the Group II and the Group III was significantly less than that in the Group I, and the postoperative analgesia effect in the Group III was obviously better than that in the other two groups (both P<0.05). @*CONCLUSION@#The general anesthesia combined with epidural anesthesia and patient-controlled epidural analgesia can effectively maintain the stable hemodynamic status in the patients and display inhibitory effect on postoperative cognitive dysfunction.

Objective To establish the reference intervals of serum pepsinogen(PG)in healthy adults in Changsha area,and to explore their distribution as well as related factors.Methods Serum PGⅠand PGⅡ levels were determined by a latex-enhanced turbidimetric immunoassay method in 1 279 subjects from Changsha area.Then PGⅠ/PGⅡ was calculated.Results The PGⅠ, PGⅡ and PGⅠ/PGⅡ levels of 1 279 healthy adult residents showed a skew distribution.The levels of serum PGⅠand PGⅠ/PGⅡ in males were 62.0 ng/mL and 4.3,which in females were 59.4 ng/mL and 4.1,significantly lower than those in males(P<0.05).Age was significantly positive correlated with serum concentrations of PGⅡ(r= 0.278,P<0.01),and was negative correla-ted with PGⅠ/PGⅡratio(r= -0.173,P<0.01).The normal reference ranges of serum PGⅠ,PGⅡ and PGⅠ/PGⅡ in males were≥56.8 ng/mL,≤22.6 ng/mL,and ≥3.3,respectively,and in females were ≥51.4 ng/mL,≤23.1 ng/mL,and ≥3.0,respec-tively.Conclusion The serum PG levels of healthy adult residents significantly show skew distributions in Changsha area,which are affected by gender and age.The establishment of reference intervals of PG contributes to clinical screening and diagnosis of gas-tric-related deseases.
