Objective To evaluate the effect of high volume hemofiltration (HVHF) treatment on inflammatory cytokine clearance and hemodynamics in children with sepsis.Methods Thirty-four cases of septic children were randomly divided into two groups:the control group(17 cases) was administrated with the routine therapy,while the observation group(17 cases) was underwent with HVHF treatment on the basis of routine therapy.The inflammatory cytokines and hemodynamics were analyzed before and after the treatment.Results (1) Before treatment,the levels of tumor necrosis factor (TNF)-α in the control group and observation group were (103.6 ±26.1) ng/L and (106.6 ±31.6) ng/L,and the levels of interleukin(IL)-6 were (772.8 ± 92.4) ng/L and (761.3 ± 89.2) ng/L,respectively.The concentration of TNF-α and IL-6 were markedly reduced in both two groups after treatment (P ＜ 0.05),with TNF-α and IL-6 reducing to (85.6±23.7) ng/L,(63.6 ±26.4) ng/L and(109.7 ±38.5) ng/L,(78.1 ±24.7) ng/L,respectively.Most importantly,the reduction in the observation group were significantly higher than that in the control group(P ＜ 0.05).(2) Before treatment,no significant differences between the observation group and the control group were observed in hemodynamics,including mean arterial pressure,saturation oxygen,and heart rate(P ＞ 0.05),whereas after the treatment,mean arterial pressure and saturation oxygen in the observation group were significantly elevated compared with those of the control group [(100.4 ± 12.1) mmHg vs.(82.2±11.7) mmHg(l mmHg=0.133kPa),(94.2±5.3)％ vs.(91.4±3.2)％,P＜0.05],andheart rate in the observation group[(85.1 ± 17.3) times/min] was significantly lower than that of the control group [(98.7 ± 18.5) times/min] (P ＜ 0.05).Conclusion HVHF treatment on septic children efficiently promotes the clearance of inflammatory cytokines and improves hemodynamic property,and thereby leads to protection of organ function and the better prognosis for septic children.

Objective To investigate the effect of Suanzaoren Decoction on hippocampus, cortex BDNF and TrKB gene expression in depression model rats. Methods Depression rat models were established by social-isolated raise and chronic stress stimulation. Suanzaoren decoction was administrated to the models. RT-PCR was adopted to detect the expression of mRNA BDNF and TrKB genes. Results The mRNA expression of BDNF and TrKB in cortex of Suanzaoren decoction high dose group、medium dose group and clomipramine group(0.213±0.094, 0.639±0.023, 1.032±0.015, 1.089±0.014, 1.580±0.012, 1.860±0.019)were all higher than the model group(0.032±0.008, 0.001±0.000), showing a significant difference among four groups (P<0.01), and the mRNA expression of BDNF and TrKB in hippocampus of Suanzaoren decoction high dose group, medium dose group and clomipramine group(0.213±0.094, 0.639±0.023, 1.032±0.015, 1.089±0.014, 1.580± 0.012, 1.860±0.019)were higher than the model group (0.021±0.015, 0.125±0.013), there was a significant difference between four groups(P<0.01). Compared with the model group, the mRNA expression of low-dose group of Suanzaoren decoction in both cortex and hippocampus of BDNF and TrKB was not significantly different to the model group(P>0.05). Conclusion Suanzaoren decoction can increase the expression of BDNF and TrKB gene, promote neuronal proliferation, and resist depression.

Objective To evaluate the effects and side effects of three different recruitment maneuvers (RM) in acute respiratory distress syndrome (ARDS) caused by extrapulmonary disease.Methods Forty-four patients of extrapulmonary ARDS, according to crossover design methods, were undergone three RM in different periods, including sustained inflation (SI), increase progressively positive end expiratory pressure (IP), pressure control ventilation (PCV). Heart rate (HR), mean arterial blood pressure (MAP), central venous pressure (CVP), oxygenation index, lung compliance were recorded before and after RM, and were analyzed for statistical analysis. Results Oxygenation index and lung compliance were increased obviously in a short time after RM, improvement of IP method were better more obviously than the other two methods [1 h oxygenation index after RM:227 ± 42 vs 190 ± 19,186 ± 21; lung compliance:(59.4±12.5 ) ml/cm H2O(1 cm H2O = 0.098 kPa) vs (50.1 ± 9.3 ), (49.7 ± 10.6) ml/cm H2O;P＜ 0.05], 2h after RM,there were no statistical difference among the three methods (P＞0.05). After RM,HR and CVPwere increased, MAP was decreased in a short time, changes of SI method were smaller than the other two inethods [10 min HR after RM: (94.0±10.3 ) beats/min vs (116.0 ± 14.8 ), ( 107.0 ± 5.7 ) beats/min; CVP:(13.7±3.1 )cm H2O vs ( 18.4 ± 6.7 ), ( 15.4 ± 2.7 )cm H2O; MAP: ( 87.0 ± 12.1 ) mm Hg( 1 mm Hg = 0.133 kPa) vs (73.0 ± 4.8), (81.0 ± 6.6) mm Hg;P＜ 0.05), 20 min after RM, there were no statistical difference among the three methods (P＞ 0.05). Conclusion When extrapulmonary ARDS undergo RM ,IP method is the most effective on increasing oxygenation index and lung compliance, SI method has the smallest side effect on hemodynamics.

Objective To research the clinical significance of acetated Ringer solution and succinylated gelatin in the fluid resuscitation of sepsis patients.Method Fifty-nine sepsis patients were divided into two groups:lactic acid Ringer solution and hetastarch (group A,27 cases)and acetated Ringer solution and suecinylated gelatin (group B,32 cases),compared the fluid resuscitation and other parameter.Results There were no significant difference in the central venous pressure,mean arterial pressure and the dose of noradrenaline (P ＞ 0.05).The activated partial thrombeplastin time in group A was longer than that in group B[(58±10),(74±13)s vs(48±7),(54 ±11) s in 6,24 hours],fibrinogen concentration was lower than that in group B [(3.3 ±0.8),(1.6±0.3)g/L vs (4.2±1.1),(2.1±0.2)g/L in 6,24 hours] (P＜0.05).Serum lactic acid,creatinine,calcium concentration in group A [(6.9±0.8)retool/L,(289 ~ 27)μ mol/L,(2.1 ±0.3)mmol/L]were higher than those in group B [(3.2 ±1.1)mmol/L, (193 ±42)μmol/L, (1.7±0.2)mmol/L](P＜0.05),there was no difference in APACHE Ⅲ scores on the third day between two groups (P＞0.05).Conclusions Acetated Ringer solution and succinylated gelatin in the fluid resuscitation of sepsis patients has the same effect,but fewer impacts on serum coagulation,serum lactic acid and renal function than lactic acid Ringer solution and hetastareh.They may be more suitable for fluid resuscitation of sepsis patients,but hypecalcemia is easy to happen,and there is no significant evidences proving the prognosis.

AIM: To investigate the possible role of nuclear transcription factor kappa B (NF-?B), Bcl-2, Bax and caspase-3 in etodolac-induced apoptosis of liver tumor SMMC7721 cell line. METHODS: Cell apoptosis was determined by flow cytometry analysis with PI staining and DNA laddering. Expression of Bcl-2 and Bax protein was measured by Western blotting. Caspase-3 activity was evaluated by active caspase-3 apoptosis kit with flow cytometry. NF-?B activation was detected by ELISA-based TransAM~(TM) NF-?B p65/p50 kit. RESULTS: Etodolac, a selective COX-2 inhibitor, stimulated apoptosis in liver tumor SMMC7721 cell line significantly. Flow cytometry showed that the apoptotic rate was 16.3%?3.1%, 19.9%?3.6%, 22.9%?3.2%, 31.2%?3.3% with different concentrations of etodolac (0.25, 0.50, 1.0 or 2.0 mmol/L), while the apoptotic peak did not appear in the control group (0 mmol/L) (P

Objective To study the changes in the level of serum IMA in patients with cardiac arrest followed by CPR,and explore the value of serum IMA in predicting prognosis of these patients after CPR.Methods (1) A total of 36 patients (25 men and 11 women) after CPR following cardiac arrest were recruited into experimental group (group C).Of them,15 cases (11 men and 4 women) and 21 cases (14men and 7 women) were assigned into resuscitation group (group R) and non resuscitation group (group NR),respectively,according to the presence or absence of ROSC.Meanwhile,another 60 healthy subjects (39 men and 21 women) matched for age and gender were recruited into healthy control group (group H).(2) The determination of the serum IMA level and comparisons of changes in serum IMA levels among groups were carried out.Results (1) The level of serum IMA in group C was higher than that in group H (P ＜ 0.05) ; The serum IMA level in group R was lower than that in group NR and higher than that in group H (P ＜0.05 for both).(2) The area under the ROC curve for serum IMA in predicting the prognosis of patients treated with CPR after cardiac arrest was 0.73.When the cut off value was 128.25 U/mL,the sensitivity and specificity were 57.1％ and 93.3％ respectively; the positive predictive value and negative predictive value were 92.3％ and 60.9％ ; positive likelihood ratio and negative likelihood ratio were 8.5 and 0.5 ; the correct diagnosis index was 72.2％,and Youden index was 50.5％.Conclusions Serum IMA has a certain value in prediction of prognosis in patients treated with CPR following cardiac arrest.

Objective To investigate the improvement of ischemic hypoxic injury of brain after the transplantation of bone marrow mesenchymal stem cells (BMSCs).Methods Rats were randomly (random number) divided into sham operation group,cardiac arrest group and BMSCs treatment group (n =10 in each group).The model of cardiac arrest was induced by asphyxia.One hour after restoration of spontaneous circulation (ROSC),green fluorescent protein labeled BMSCs were transplanted via tail vein injection.At 3 and 7 days after transplantation,frozen sections of hippocampus was stained with hematoxylin-eosin (HE).The rest of brain tissue was weighed by an electronic balance.Brain water content (％) was calculated as (wet weight-dry weight) / wet weight × 100％.Results ①BMSCs were observed in hippocampus at 3 and 7 days after transplantation under fluorescent microscopy.②Compared with sham operation group and BMSCs treatment group,brain water content in cardiac arrest group was higher (all P ＜ 0.05).HE staining results showed that BMSCs transplantation could lessen hypoxia ischemia damage on brain.Conclusions BMSCs reduced the neurons damage induced by cardiac arrest and promoted neurological function recovery.

Objective To observe the clinical effects of insulin glargine combined with novonorm in treatment of patients with newly diagnosed type 2 diabetes. Methods 112 cases of newly diagnosed type 2 diabetes patients were randomly separated into observation group(56 cases)and control group(56 cases). Observation group was treated with insulin glargine combined with novonorm. Control group was treated with novolin30R. The levels of FPG,2hPG and HbA1c before and after treatment,the control time of blood sugar,amounts of insulin and incidence of low blood sugar were observed in both groups. Results Compared with pre-treatment, FPG,2hPG and HbA1 c were significantly decreased (all P ＜0.05) after treatment, but there were no significant differences in both two groups (P ＞0. 05). The control time of blood sugar, amounts of insulin and incidence of low blood sugar in observation group were significantly lower than those in control group (all P ＜ 0.05). Conclusion Insulin glargine combined with novonorm in treatment of patients with newly diagnosed type 2 diabetes could effectively control blood sugar,shorten the control time of blood sugar,decrease amounts of insulin,and low incidence of low blood sugar.
