Objective:To explore the early clinical features and the prognostic factors of children with septic shock in PICU.Methods:A retrospective analysis was conducted at PICU of the Children′s Hospital, Capital Institute of Pediatrics from January 2016 to November 2018, totally 56 children diagnosed as septic shock were enrolled in the study.According to the prognosis of 28 days, the patients were divided into death group and survival group; according to the lowest pediatric critical score (PCIS) within 24 hours after admission to PICU, the children were divided into non-critical group (>80 points), critical group (70-80 points) and extremely critical group (<70 points). The clinical characteristics of early stage in each group were analyzed and compared.Results:Of the 56 children with septic shock, 32 were males and 24 were females, and the mean age was 12.0(1.0, 180.0) months.The overall mortality rate was 37.5%(21/56). The mortality of non-critical group, critical group and extremely critical group were 12.5%(2/16), 16.7%(1/6) and 52.9%(18/34), respectively.There were no statistically significant differences between survival group and death group in gender and age, PICU stay time, heart rate, mean arterial pressure at 1 hour and 24 hours, ventilator using and the duration of mechanical ventilation(all P>0.05). The vasoactive-inotropic score(VIS) at 6 hours and 24 hours of death group were significantly higher than those in survival group[19.0(5.0-29.5) vs.5.0(0.0-10.0), 22.5(3.5-43.8) vs.5.3(0.0-13.5)]. The scores of PCIS in death group were less than that in survival group(57.3±10.7 vs.72.8±12.0)( t=4.85, P<0.001). The lactate level in survival group before resuscitation was statistically lower than that in death group[1.8(1.3-2.8) mmol/L vs.4.5(2.4-8.4)mmol/L]( Z<-3.70, P<0.05). At 1 hour, 6 hours and 24 hours after treatment, fluid resuscitation volume in death group were markedly higher than that in survival group[1 hour: (41.8±5.8)ml/kg vs.(38.5±5.3)ml/kg, t=-2.22, P<0.05; 6 hours: (69.5±4.4)ml/kg vs.(59.9±3.5)ml/kg, t=-8.96, P<0.05; 24 hours: (122.3±19.6)ml/kg vs.(111.7±16.2)ml/kg, t=-2.20, P<0.05]. Multiple sample comparisons found significant differences between the non-critical group[(60.0±3.5) ml/kg] and the extremely critical group[(65.3±6.0) ml/kg, P<0.05], and pairwise comparison of fliud intake within 1 h and 24 h showed no statistically differences( P>0.05). In the univariate analysis, variables significantly associated with death in septic shock were lactic acid before resuscitation and the 24 h lactate clearance rate, VIS 6 h, VIS 24 h, procalcitonin, ejection fraction, PCIS, 6 h-fluid resuscitation volume and multiple organ dysfunction (MODS). The Logistic regression showed that 6 h-fluid resuscitation volume, PCIS, lactic acid and MODS were independent risk factors.ROC curve analysis showed the AUCs of 6 h-fluid resuscitation volume, PCIS, early lactic acid and MODS for predicting death of septic shock children were 0.947, 0.835, 0.797 and 0.761, respectively. Conclusion:The mortality of septic shock is high, and decreased PCIS, elected serum lactic acid level and early fluid resuscitation, and MODS are risk factors associated with the death of septic shock.

OBJECTIVETo explore the expression of p-p38 MAPK protein and the number of astrocytes expressing p-p38 MAPK in CA1 hippocampus in rats during the induction of brain ischemic tolerance induced by intermittent hypobaric hypoxia (IH) preconditioning.

METHODSThirty healthy adult male Wistar rats were randomly divided into 6 groups (n = 5 in each group): sham 0 min group, IH + sham 0 min group, sham 7 d group, IH + sham 7 d group, Ischemia (Is) 7 d group, and IH + Is 7 d group. Neuropathological evaluation was performed by thionine staining in CA1 hippocampus in rats. The expression of p-p38 MAPK in CA1 hippocampus was observed by immunohistochemical staining. And the number of astrocytes expressing p-p38 MAPK was observed by immunofluorescent double labeling.

RESULTSThe results showed that IH preconditioning induced brain ischemic tolerance successfully. At the same time, IH preconditioning obviously up-regulated the expression of p-p38 MAPK protein in CA1 hippocampus, and also increased the number of astrocytes expressing p-p38 MAPK.

CONCLUSIONIt might be concluded that IH preconditioning induced brain ischemic tolerance by up-regulating the expression of p-p38 MAPK protein in pyramidal neurones and astrocytes.

OBJECTIVETo observe clinical effect of integrated Chinese medical (CM) treatment (as maintenance therapy) on the progression-free survival (PFS) and overall survival (OS) in patients with advanced non-small-cell lung cancer (NSCLC) after first-line chemotherapy.

METHODSThe study was a prospective, randomized, controlled clinical trial. Totally 69 non-progressive advanced NSCLC patients treated with first-line chemotherapy were randomly assigned to the test group (34 cases) and the control group (35 cases). Patients in the control group were treated with one Western drug chemotherapy (Gemcitabine or Alimta or docetaxel). Those in the test group were treated with integrated CM treatment (CM decoction, CM Intravenous preparation, and point application). Each cycle consisted of 21 days. Treatment lasted till the disease progressed, or intolerable toxic/adverse reactions occurred, or patients refused to continue the treatment. Patients' life spans were regularly followed-up.

RESULTS(1) The median cycle of maintenance therapy was 2 cycles for two groups with no statistical difference (P =0.274). The median PFS was 12.43 weeks in the test group and 10.00 weeks in the control group, showing statistical difference (P =0.025). The middle survival time (MST) was 18.8 months in the test group and 16.73 months in the control group, showing no statistical difference (P =0.437).

CONCLUSIONCM treatment (as maintenance therapy) showed quail effect to one Western drug chemotherapy in prolonging patients' life span.

Treatment based on syndrome differentiation is an essential feature of traditional Chinese medical diagnosis. The interventions based on changes of syndrome types in randomized controlled trials are complicated, leading to the difficulty of blind method enforcement. This article described a double-blind method. It could be used in randomized controlled trials under the condition of different syndrome types and different medications. It numbered drugs in two stages, and in two phases to achieve double-blind. This method not only guaranteed investigators and subjects to be in blinded conditions, but also achieved using different medications for patients of different syndromes. It also caused no drug waste. It was scientific and feasible.
