ABSTRACT
Objective To study the effect of hypertonic sodium chloride in the treatment of patients with traumatic hemorrhagic shock and the effects of NO and neutrophil surface CD 18 on the serum.Methods 120 patients with traumatic hemorrhagic shock were admitted to the hospital from December 2013 to December 2016,and randomly divided into the observation group and the control group.The control group was given nal-oxone injection,while the observation group was given hypertonic Sodium Chloride Solution.The two groups were compared before and after treatment,hemoglobin concentration,total infusion,24 h mortality,recovery time and adverse reactions,and the patients′hemodynamic and NO and CD18 levels were measured on the ser-um.Results After 24 h treatment,the observation group total infusion was(1 203.13 ± 117.82)mL,the re-covery time was(60.73 ± 5.63)min,24 h mortality rate of 5.00% was significantly lower than the control group total infusion(1 672.38 ± 123.64)mL,the recovery time(71.82 ± 6.19)min,24 h death rate 16.67%, hemoglobin concentration(91.24 ± 5.71)g/L higher than that of the control group(79.45 ± 6.18)g/L,the difference was statistically significant(P<0.05).Before treatment,there was no difference in the contents of NO and CD18 between the two groups.After treatment,two groups of patients with serum NO,CD18 content significantly decreased,but the observation group NO(20.27 ± 6.65)mol/L,CD18(41.67 ± 13.24)ng/mL were significantly lower than the control group NO(29.12 ± 8.23)mol/L,CD18(52.64 ± 13.51)ng/mL,the difference were statistically significant(P<0.05).Before treatment,two groups of patients with hemodynam-ic indexes of arterial and venous pressure,no difference in heart rate(P> 0.05);after treatment,the two groups of patients with arterial and venous pressure and heart rate were improved,but the change index of the observation group than in the control group was stable,the difference was statistically significant(P<0.05). The complication rate of the observation group was 10%(6/60),which was significantly lower than that of the control group(15/60),and the difference was statistically significant(P<0.05).Conclusion The infiltra-tion of sodium chloride intravenous infusion could significantly decreased CD 18 and NO levels in the serum of the patients,the patients with stable hemodynamics,reduced the incidence of complications,worthy of clinical reference.
ABSTRACT
Objective To observe the effect of hypertonic saline complex solution (hypertonic saline plus hydroxyethyl starch,HSH) on patients with severe cerebral trauma,high intracranial pressure and shock by the measurement of the changes of the mean arterial pressure (MAP),central venous pressure (CVP) and intracranial pressure (ICP),as well as GOS score changes followed up for 6 months,in order to determine the value of HSH treatment in severe cerebral trauma,intracranial hypertension and shock.Methods Sixty patients with severe brain injury and uncorrected hemorrhagic shock were selected,while the degree of coma was assessed by using GCS score,and shock severity was estimated by using the shock index (SI) score.The patients were randomly divided into HSH group (n =30) and mannitol group (MT group,n =30).Thirty minutes,60 min and 120 min after administration either solution,The changes of MAP,CVP and ICP were observed in two groups,and all patients were followed up for 6 months to observe the outcomes of patients.Results There were no statistically significant differences in age,gender,GCS score,SI scores,and other medication between two groups (P ＞ 0.05),and they were comparable between two groups.After resuscitation of patients in two groups,MAP and CVP were elevated,but the effect of HSH appeared sooner and higher within 30 minutes [MAP (63.1 ± 8.8) mmHg vs.(51.0-9.3) mmHg] (P ＜ 0.05);At the same time,ICP dropped more than 10％ lower [ICP (27.3 ± 5.9) mmHg vs.(32.8 ± 4.1) mmHg] (P ＜0.05),while the effect of MT appeared more slowly in hemodynamic improvement;at 120 min,the increase in MAP and reduction in ICP in HSH group were more significant than those in MT group [MAP (65.9 ± 13.2) mmHg vs.(60.4 ±7.2) mmHg] (P ＜0.01);the ICP [(22.2 ±4.7) mmHg vs.(28.1 ±6.1) mmHg] (P ＜ 0.01).Followed up for 6 months,good recovery rate in HSH group was higher and poor recovery rate was lower than those in MT group.Conclusions In patients with acute intracranial hypertension and uncorrected hemorrhagic shock,the employment of hypertonic saline plus hydroxyethyl starch solution can produce faster and more effective therapy for shock and reduce intracranial pressure,improving the long-term neurological function of patients.

ABSTRACT
Objective To investigate the protective effect and potential mechanisms of hypertonic sodium chloride hydroxyethyl starch solution (HSH) against the cerebral vasospasm (CVS) following subarachnoid hemorrhage (SAH).Methods Twenty-four male Sprague-Dawley (SD) rats were randomly assigned to four groups according to the random number table,with 6 rats in each group.The SAH-CVS model was reproduced by injection of the blood twice through the cisterna magna.Rats in both model and HSH treatment groups received 8 mL/kg normal saline (NS) or HSH treatment everyday via caudal vein.Rats in sham group were injected with 1.5 mL/kg NS into cisterna magna followed by 8 mL/kg NS treatment.Rats in normal group received no treatment.Rats were sacrificed to harvest basilar artery after 7 days.The thickness of vessel wall and lumen area were measured using hematoxylin-eosin (HE) staining.The rate of apoptosis of vascular smooth muscle cell (VSMC) was assessed using flow cytometry.Caspase-3 activity was measured by a fluorometric assay.The expressions of Bax and Bcl-2 were determined by Western Blot.Intracellular reactive oxygen species (ROS) was detected by H2DCFDA.Results Compared with normal group,increased thickness of vessel wall (μm:27.72 ± 1.94 vs.18.30 ± 1.10,P＜0.05),decreased lumen area (μm2:26 115 ± 1 991 vs.55 080 ± 2 091,P＜0.05),and elevation of rate of apoptosis of VSMCs [(35.05 ± 5.54) ％ vs.(5.93 ± 1.53) ％,P＜ 0.05] were found in model group.Compared with model group,decreased thickness of vessel wall (μm:22.55 ± 1.50 vs.27.72 ± 1.94,P＜0.05),increase of lumen area (μm2:48 115 ±2 460 vs.26 115 ± 1 991,P＜0.05),and depressed rate of apoptosis of VSMCs [(16.54 ± 5.94) ％ vs.(35.05 ± 5.54) ％,P＜ 0.05] were found in HSH treatment group.Caspase-3 activity,intracellular ROS level,Bax and Bcl-2 expressions in model group were (188.40 ± 19.35)％,(163.50 ± 17.02)％,(208.71 ± 26.04)％ and (44.52 ± 9.61) ％ of those of normal group,and the differences of these parameters between model and normal groups were statistically significant (all P＜0.05).Caspase-3 activity,intracellular ROS level,Bax and Bcl-2 expressions in HSH treatment group were (135.05 ± 19.52)％,(119.44 ± 11.50)％,(139.20 ± 18.04)％ and (85.35 ± 13.12)％ of those of normal group,respectively,and the differences of these parameters between HSH treatment and model groups were statistically significant (all P＜0.05).The differences of all measurements between sham and normal groups were not statistically significant.Conclusion The current results demonstrate that HSH attenuates the SAH-induced CVS,alleviates thickness of vessel wall,and increases lumen area via inhibition of VSMCs apoptosis.
