Objective To investigate whether hypertonic saline (HS) can induce the synthesis and release of glutamate in cultured hypothalamic astrocytes or C6 cell line. Methods Astrocytes were isolated, cultured, purified and identified from the hypothalamus of newborn rat (1 day). The astrocytes were randomly divided into five groups: isotonic (IS) and HS groups, astrocytes were incubated by IS and HS (320 mosM NaCl) medium, respectively, for 1, 3, 5, 10 or 15 rain; carbenoxolone (CBX) +IS and CBX+HS groups, astrocytes were pre-treated with CBX (100 mmol/L) for 1 h at 37℃ in a 5% CO2 / 95% atmosphere, then removed to IS and HS medium, respectively, for 1, 3, 5, 10 or 15 min; Ca2++HS group, astrocytes were pre-incubated with Ca2+ (1 000 μmol/L) for 1 h at 37℃ in a 5% CO2 / 95% atmosphere, followed by a wash with isotonic FBS/DMEM, and then removed to hypertonic saline for 1, 3, 5, 10 or 15 min. The media of five groups were collected to analyze the medium glutamate concentration with high performance liquid chromatography. The astrocytes were fixed and double immunofluorescent stained with anti-glial fibrillary acidic protein (GFAP) and anti-glutamate. The C6 cells were divided into four groups: IS, HS, CBX+IS and CBX+HS groups, and used for quantitative measurement of glutamate in cells by flow cytometry (FCM). Results (1) Anti-GFAP immunofluorescent signal revealed no significant difference among various time points in each group, or among the five groups. (2) The anti-glutamate immunofluorescent signal was increased in HS group and peaked at 5 min, and decreased and returned to the level of IS group at 15 rain (P 〈 0.01 vs the 5 min of HS group). In CBX+HS group, the glutamate intensity was higher than that in CBX+IS and HS groups. (3) The medium glutamate concentration had no change after treatment with HS for 1 and 3 min, while increased markedly after treatment for 5 min to 15 min (P 〈 0.01 vs 1 min and 3 min). On the contrary, the medium glutamate concentrations in the CBX+HS or Ca2++HS group were significant lower than that in the HS group (P 〈 0.01). (4) FCM showed HS and CBX+HS induced glutamate increase in C6 cells. Conclusion HS induced cultured rat hypothalamic astrocytes or C6 cells to synthesize and release glutamate; CBX could block glutamate release, but could not disrupt glutamate synthesis. 展开更多

AIM:To investigate the effect of local intestinal perfusion with hypertonic saline(HTS) on intestinal ischemia-reperfusion injury(IRI) in bothex vivo andin vivo rat models.METHODS:All experiments were performed on male Wistar rats anesthetized with pentobarbital sodium given intraperitoneally at a dose of 60 mg/kg.Ex vivo vascularly perfused rat intestine was subjected to 60-min ischemia and either 30-min reperfusion with isotonic buffer(controls),or 5 min with HTS of 365 or 415 mOsm/L osmolarity(HTS 365mOsm or HTS 415mOsm,respectively) followed by 25-min reperfusion with isotonic buffer.The vascular intestinal perfusate flow(IPF) rate was determined by collection of the effluent from the portal vein in a calibrated tube.Spontaneous intestinal contraction rate was monitored throughout.Irreversible intestinal injury or area of necrosis(AN) was evaluated histochemically using 2.3.5-triphenyltetrazolium chloride staining.In vivo,30-min ischemia was followed by either 30-min blood perfusion or 5-min reperfusion with HTS 365mOsm through the superior mesenteric artery(SMA) followed by 25-min blood perfusion.Arterial blood pressure(BP) was measured in the common carotid artery using a miniature pressure transducer.Histological injury was evaluated in both preparations using the Chui score.RESULTS:Ex vivo,intestinal IRI resulted in a reduction in the IPF rate during reperfusion(P < 0.05 vs sham).The postischemic recovery of the IPF rate did not differ between the controls and the HTS 365mOsm group.In the HTS 415mOsm group,postischemic IPF rates were lower than in the controls and the HTS 365mOsm group(P < 0.05).The intestinal contraction rate was similar at baseline in all groups.An increase in this parameter was observed during the first 10 min of reperfusion in the control group as compared to the sham-treated group,but no such increase was seen in the HTS 365mOsm group.In controls,AN averaged 14.8% ± 5.07% of the total tissue volume.Administration of HTS 365mOsm for 5 min after 60-min ischemia resulted in decrease in AN(5.1% ± 1.20% vs controls,P < 0.01).However,perfusion of the intestine with the HTS of greater osmolarity(HTS 415mOsm) failed to protect the intestine from irreversible injury.The Chiu score was lower in the HTS 365mOsm group in comparison with controls(2.4 ± 0.54 vs 3.2 ± 0.44,P = 0.042),while intestinal perfusion with HTS 415mOsm failed to improve the Chiu score.Intestinal reperfusion with HTS 365mOsm in the in vivo series secured rapid recovery of BP after its transient fall,whereas in the controls no recovery was seen.The Chiu score was lower in the HTS 365mOsm group vs controls(3.1 ± 0.26 and 3.8 ± 0.22,P = 0.0079 respectively,),although the magnitude of the effect was lower than in the ex vivo series.CONCLUSION:Brief intestinal postischemic perfusion with HTS 365mOsm through the SMA followed by blood flow restoration is a protective procedure that could be used for the prevention of intestinal IRI. 展开更多

They were randomly allocatedinto three groups; each group included 30 patients treatedwith intravariceal sclerosant injections in biweeklysessions till complete obturation of gastric varices;Group I (n-butyl-2-cyanoacrylate; Histoacryl?), GroupII (iso-amyl-2-cyanoacrylate; Amcrylate?) and GroupIII (mixture of 72% chromated glycerin; Scleremo?with glucose solution 25%). All the procedures wereperformed electively without active bleeding. Recruitedpatients were followed up for 3 mo.RESULTS: 26% of Scleremo group had bleeding duringpuncture vs 3.3% in each of the other two groups withsignificant difference, (P 〈 0.05). None of Scleremogroup had needle obstruction vs 13.3% in each of theother two groups with no significant difference, (P 〉0.05). Rebleeding occurred in 13.3% of Histoacryl andAmcrylate groups vs 0% in Scleremo group with nosignificant difference. The in hospital mortality was 6.6%in both Histoacryl and Amcrylate groups, while it was0% in Scleremo group with no significant difference. Inthe first and second sessions, the amount of Scleremoneeded for obturation was significantly high, while the amount of Histoacryl was significantly low. Scleremo was the less costly of the two treatments. CONCLUSION: All used sclerosant substances showed efficacy and success in management of gastric varices with no significant differences except in total amount,cost and bleeding during puncture. 展开更多

Objective: To investigate the potential and early effect of hypertonic saline resuscitation on T-lymphocyte sub- populations in rats with hemorrhagic shock. Methods: A model of rat with severe hemorrhagic shock was established in 18 Sprague-Dawley (SD) rats. The rats were randomly divided into Sham group, HTS group (hypertonic saline resuscitation group) and NS group (normal saline resuscitation group). Each group contained 6 rats. The CD4+ and CD8+ subpopulations of T-lymphocytes in peripheral blood were detected respectively before shock and after resuscitation by double antibody labelling and flow cytometry. Results: In the early stage after hemorrhagic shock, fluid resuscitation and emergency treatment, the CD4+ lymphocytes of peripheral blood in HTS and NS groups markedly increased. Small volume resuscitation with HTS also induced peripheral CD8+ lymphocytes to a certain extent, whereas NS resuscitation showed no effect in this respect. Consequently, compared with Sham and HTS groups, CD4+/CD8+ ratio of peripheral blood in NS group was obviously increased, and showed statistically differences. Conclusion: In this model of rat with severe hemorrhagic shock, small volume resuscitation with HTS is more effective than NS in reducing immunologic disorders and promoting a more balanced profile of T-lymphocyte subpopula- tions regulating network. 展开更多

AIM: To investigate the effects of 7.5% hypertonic saline on positive fluid balance and negative fluid balance, after radical surgery for gastrointestinal carcinoma. METHODS: Fifty-two patients with gastrointestinal carcinoma undergoing radical surgery were studied. The patients were assigned to receive either Ringer lactate solution following 4 mL/kg of 7.5% hypertonic saline (the experimental group, n = 26) or Ringer lactate solution (the control group, n = 26) during the early postoperative period in SICU. Fluid infusion volumes, urine outputs, fluid balance, body weight change, PaO2/FiO2 ratio, anal exhaust time as well as the incidence of complication and mortality were compared between the two groups. RESULTS: Urine outputs on the operative day and the first postoperative day in experimental group were significantly more than in control group (P<0.000001, P=0.000114). Fluid infusion volumes on the operative day and the first postoperative day were significantly less in experimental group than in control group (P= 0.000042, P= 0.000415). The volumes of the positive fluid balance on the operative day and during the first 48 h after surgery, in experimental group, were significantly less than in control group (P<0.000001). Body weight gain post-surgery was significantly lower in experimental group than in control group (P<0.000001). The body weight fall in experimental group occurred earlier than in control group (P<0.000001). PaO2/FiO2 ratio after surgery was higher in experimental group than in control group (P= 0.000111). The postoperative anal exhaust time in experimental group was earlier than in control group (P= 0.000006). The overall incidence of complications and the incidence of pulmonary infection were lower in experimental group than in control group (P= 0.0175, P= 0.0374). CONCLUSION: 7.5% hypertonic saline has an intense diuretic effect and causes mobilization of the retained fluid, which could reduce fluid infusion volumes and positive fluid balance after radical surgery for gastrointestinal carcinoma, as well as, accelerate the early appearance of negative fluid balance after the surgery, improve the oxygen diffusing capacity of the patients' alveoli, and lower the overall incidence of complications and pulmonary infection after the surgery. 展开更多

Objective: To investigate the early effects of hypertonic and isotonic saline solutions on apoptosis of intestinal mucosa in rats with hemorrhagic shock. Methods: A model of rat with severe hemorrhagic shock was established in 21 Sprague-Dawley (SD) rats. The rats were randomly divided into the sham group, normal saline resuscitation (NS) group, and hypertonic saline resuscitation (HTS) group, with 7 in each group. We detected and compared the apoptosis in small intestinal mucosa of rats after hemorrhagic shock and resuscitation by terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL), FITC (fluo- rescein-iso-thiocyanate)-Annexin V/PI (propidium iodide) double staining method, and flow cytometry. Results: In the early stage of hemorrhagic shock and resuscitation, marked apoptosis of small intestinal mucosa in the rats of both NS and HTS groups was observed. The numbers of apoptotic cells in these two groups were significantly greater than that in the sham group (P<0.01). In the HTS group, the apoptic cells significantly decreased, compared with the NS group (P<0.01). Conclusion: In this rat model of severe hemorrhagic shock, the HTS resuscitation of small volume is more effective than the NS resuscitation in reducing apoptosis of intestinal mucosa in rats, which may improve the prognosis of trauma. 展开更多

AIM: To investigate the effects of hypertonic saline in the neurocritical care population.METHODS: We retrospectively reviewed our hospital's use of hypertonic saline(HS) since March of 2005, and prospectively since October 2010. Comparisons were made between admission diagnoses, creatinine change(Cr), and HS formulation(3% Na Cl, 3% Na Cl/sodium acetate mix, and 23.4% Na Cl) to patients receiving normal saline or lactated ringers. The patients(n = 1329) of the retrospective portion were identified. The data presented represents the first 230 patients with data. RESULTS: Significant differences in Acute Physiology and Chronic Health Evaluation Ⅱ scores and GlasgowComa Scale scores occurred between different saline formulations. No significant correlation of Cl- or Na+ with Cr, nor with saline types, occurred. When dichotomized by diagnosis, significant correlations appear. Traumatic brain injury(TBI) patients demonstrated moderate correlation between Na+ and Cr of 0.45. Stroke patients demonstrated weak correlations between Na+ and Cr, and Cl- and Cr(0.19 for both). Patients receiving HS and not diagnosed with intracerebral hemorrhage, stroke, subarachnoid hemorrhage, or TBI demonstrated a weak but significant correlation between Cl- and Cr at 0.29.CONCLUSION: Cr directly correlates with Na+ or Cl- in stroke, Na+ in TBI, and Cl- in other populations. Prospective comparison of HS and renal function is needed. 展开更多

BACKGROUND:Liver ischemia reperfusion(IR)injury triggers a systemic inflammatory response and is the main cause of organ dysfunction and adverse postoperative outcomes after liver surgery.Pentoxifylline(PTX)and hypertonic saline solution(HTS)have been identified to have beneficial effects against IR injury.This study aimed to investigate if the addition of PTX to HTS is superior to HTS alone for the prevention of liver IR injury.METHODS: Male Wistar rats were allocated into three groups. Control rats underwent 60 minutes of partial liver ischemia, HTS rats were treated with 0.4 mL/kg of intravenous 7.5% NaCl 15 minutes before reperfusion, and HPTX group were treated with 7.5% NaC1 plus 25 mg/kg of PTX 15 minutes before reperfusion. Samples were collected after reperfusion for determination of ALT, AST, TNF-α, IL-6, IL-10, mitochondrial respiration, lipid peroxidation, pulmonary permeability and myeloperoxidase. RESULTS: HPTX significantly decreased TNF-α 30 minutes after reperfusion. HPTX and HTS significantly decreased ALT,AST, IL-6, mitochondrial dysfunction and pulmonary myelo- peroxidase 4 hours after reperfusion. Compared with HTS only, HPTX significantly decreased hepatic oxidative stress 4 hours after reperfusion and pulmonary permeability 4 and 12 hours after reperfusion. CONCLUSION: This study showed that PTX added the beneficial effects of HTS on liver IR injury through decreases of hepatic oxidative stress and pulmonary permeability. 展开更多

Objective: The efficacy of Ji Desheng snake pills combined with hypertonic glucose external application in treating drug-induced superficial phlebitis caused by parenteral nutrition (PN) is observed. Methods: Fifty-two cases of drug-induced superficial phlebitis after peripheral parenteral nutrition (PPN) were selected, which were randomly divided into experimental group and control group in accordance with the phlebitis grading. In the experimental group, Ji Desheng snake pills were crushed to make a paste with 50% glucose solution, which was then applied to the affected area of phlebitis, the surface was covered with clean gauze, and properly fixed with tape or bandage. The drug was replaced once a day. In the control group, the gauze soaked with 50% magnesium sulfate solution was used, which was applied to the affected part three times a day in wet, and the efficacy was observed respectively on the 1st, 3rd, 5th and 7th days after applying the drug. Results: On the 1st and 3rd days after treatment, the observed effective rate of the experimental group was higher than that of the control group (42.31% vs. 15.38% and 76.92% vs. 46.15%, respectively). The difference was statistically significant (p th and 7th days after treatment, there was no statistical significance with respect to the efficacy between the experimental group and the control group (p > 0.05). Conclusion: The significant efficacy could be found in early stage after drug-induced superficial phlebitis was treated by Ji Desheng snake pills combined with hypertonic glucose external application, which was superior to that of the traditional treatment of wet application by using gauze soaked in 50% magnesium sulfate solution. 展开更多

Hypertonicity causes severe clinical manifestations and is associated with mortality and severe short-term and long-term neurological sequelae. The main clinical syndromes of hypertonicity are hypernatremia and hyperglycemia. Hypernatremia results from relative excess of body sodium over body water. Loss of water in excess of intake, gain of sodium salts in excess of losses or a combination of the two are the main mechanisms of hypernatremia. Hypernatremia can be hypervolemic, euvolemic or hypo-volemic. The management of hypernatremia addresses both a quantitative replacement of water and, if present, sodium defcit, and correction of the underlying pathophysiologic process that led to hypernatremia. Hypertonicity in hyperglycemia has two components, solute gain secondary to glucose accumulation in the extracellular compartment and water loss through hyperglycemic osmotic diuresis in excess of the losses of sodium and potassium. Differentiating between these two components of hypertonicity has major therapeutic implications because the frst component will be reversed simply by normalization of serum glucose concentration while the second component will require hypotonic fuid replacement. An estimate of the magnitude of the relative water deficit secondary to osmotic diuresis is obtainedby the corrected sodium concentration, which representsa calculated value of the serum sodium concentrationthat would result from reduction of the serum glucoseconcentration to a normal level. 展开更多

AIM To test the safety and effectiveness of hypertonic saline solution(HSS + F) as a strategy for weight loss andprevention of further deterioration of renal function.METHODS Patients admitted with acute decompensated heart failure(ADHF) who received HSS + F were included in the study. After a period of a standard ADHF treatment, our patients received an intravenous infusion of furosemide(250 mg) combined with HSS(150 mL of 3% NaCl) twice a day for a mean duration of 2.3 d. Our primary outcomes were weight loss and a change in serum creatinine per day of treatment. The parameters of the period prior to treatment with HSS + F were compared with those of the period with HSS + F. RESULTS A total of 47 patients were included. The mean creatinine on admission was 155 μmol/L ± 65 μmol/L, the ejection fraction was 40% ± 17%. The experimental treatment(HSS + F) resulted in greater weight loss per day of treatment than the standard treatment(-1.4 kg/d ± 1.4 kg/d vs-0.4 kg/d ± 1.0 kg/d, P = 0.0168). Importantly, the change in creatinine was not significantly different.CONCLUSION This study supports the effectiveness of HSS + F on weight loss in patients with ADHF. The safety profile, particularly with regard to renal function, leads us to believe that HSS + F may be a valuable option for those patients presenting with ADHF who do not respond to conventional treatment with intravenous furosemide alone. 展开更多

To compare the early effects of hypertonic and isotonic saline resuscitation on heme oxygenase-1 (HO-1) expression in organs of rats with hemorrhagic shock. Rats were randomly divided into hypertonic saline resuscitation (HTS), normal saline resuscitation (NS) and sham groups. HO-1 mRNA, protein expression and apoptosis were evaluated in organs. In the HTS group, significant difference was noted in HO-1 protein in small intestinal mucosa and liver compared with the NS and sham groups, and in HO-1 mRNA in liver and kidney compared with the sham group. The apoptosis of small intestinal mucosa, liver, heart, and lung was significantly lower in the HTS group than that in the NS group. In this study, small volume resuscitation with HTS can efficiently up-regulate the expression level of HO-1 in small intestinal mucosa and liver, which may be one of the mechanisms alleviating organ damage. 展开更多

To examine the aging-related changes of microglia and astrocytes in hypothalamus of rats after intraperitoneal injection of hypertonic saline in rats, old- and young-aged rats were injected with hypertonic saline solution into peritoneal cavity. Lectin histochemical techniques using Ricinus communis agglutinin-1 (RCA-1) and immunocytochemical method employing antibody against glial fibrillary acidic protein (GFAP) were used to demonstrate microglia and astrocytes in the hypothalamus of the rats, and the positively-stained cells were analyzed by computer-assisted image analysis system. Our results showed that the numbers of microglia and astrocytes were significantly increased in the hypothalamus of old-aged rats. After intraperitoneal injection of hypertonic saline, the number of microglia was significantly decreased in the hypothalamus of both young- and oldaged groups. After introperitoneal injection of hypertonic saline, the number of GFAP positive cells was significantly increased in the hypothalamus of young rats, but the number of GFAP positive cells did not show significant change in the hypothalamus of old rats. It is concluded that in the hypothalamus of old-aged rats, the increase of microglia may be related with the aging or degeneration of neurons, and the increase of astrocytes may provide more nourishment required by the aged neurons. The microglia and astrocytes in the hypothalamus of the two group rats may be affected by hypertonic saline, and the response of these cells to the stimuli is characterized by some aging-related changes. 展开更多

The study is aimed at examining the effect of the 7. 5% hypertonic saline (HTS) on blood flow and en ergy metabolism in the gastric mucosa after hemorrhagic shock. The experiment was performed on 40 rabbits subjected to rapid hemorrhage (18 ml/kg). At 60 min after hemorrhagic shock,animals were given either HTS or 0. 9% normal saline in a volume 1/4 as much as the shed blood. Blood flow was measured using radioactive microspheres. Adenosine nucleotides were assayed using high performance liquid chromatograph. Resuscitation with HTS caused a significant increase in mean arterial pressure (MAP). At 30 min after HTS infusion.the increase in blood flow at the gastric mucosal layer was more pronounced than that at the gastric muscular layer. A significant rise in levels of ATP with reduced ATPase activity was observed in our study. The results suggest that 7. 5% hypertonic saline solution improved the blood flow and energy metabolism in the gastric mucosa. This effect may help to protect the gastric mucosa against injury caused by local ischemia. 展开更多

Cystic fibrosis(CF) is a multisystem disorder with significantly shortened life expectancy. The major cause of mortality and morbidity is lung disease with increasing pulmonary exacerbations and decline in lung function predicting significantly poorer outcomes. The pathogenesis of lung disease in CF is characterised in part by decreased airway surface liquid volume and subsequent failure of normal mucociliary clearance. This leads to accumulation of viscous mucus in the CF airway, providing an ideal environment for bacterial pathogens to grow and colonise, propagating airway inflammation in CF. The use of nebulised hypertonic saline(HTS) treatments has been shown to improve mucus clearance in CF and impact positively upon exacerbations, quality of life, and lung function. Several mechanisms of HTS likely improve outcome, resulting in clinically relevant enhancement in disease parameters related to increase in mucociliary clearance. There is increasing evidence to suggest that HTS is also beneficial through its anti-inflammatory properties and its ability to reduce bacterial activity and biofilm formation. This review will first describe the use of HTS in treatment of CF focusing on its efficacy and tolerability. The emphasis will then change to the potential benefits of aerosolized HTS for the attenuation of receptor mediated neutrophil functions, including down-regulation of oxidative burst activity, adhesion molecule expression, and the suppression of neutrophil degranulation of proteolytic enzymes. 展开更多

Hypertonic saline (HS) has been applied in several med- ical areas such as pneumology (asthma, cystic fibrosis and bronchiolytis), endocrinology (hyponatremia) and especially in emergency medicine, in traumatic and in- flammatory/infectious disorders. It may be composed of 3% or 7.5% sodium chlorate. By far, 3% solution is the most widely studied and used solution (Pinto et al., 2006, 2015; Dekker et al., 2014; Gantner et al., 2014; Shein et al., 2014). 展开更多

This study aimed to investigate whether a small volume of 7.2% hypertonic saline solution with 6% dextran 70 (HSD) is superior to mannitol in vasodilatation of encephalic vessels in the dogs using magnetic resonance imaging (MRI). Fifteen healthy 2.4 ± 0.9 year-old purpose-bred male Beagle dogs were assigned to receive 5 mL/kg of isotonic saline solution (ISS) as control, 20% mannitol or HSD infusion at a flow rate of 20 mL/kg/hours via right cephalic vein.Venous blood samples were collected immediately before fluid infusion (pre) and every 15 minutes until 120 minutes after the initiation of fluid infusion. Immediately after collection of each blood sample, T1 and T2-weighted magnetic resonance imaging recordings were undergone. Immediately after HSD infusion, the area of the cross-section of superior sagittal sinus was significantly greater than that of beagles in the other groups (p p < 0.001). Our results indicate that HSD induced a rapid and strong reduction in the area of the cross-section of CSF more than mannitol did. Therefore, it is suggested that 5 mL/kg of HSD might be superior to isovolume of mannitol in inducing vasodilatation in the dog. 展开更多

Introduction: Chronic sinusitis affects all age groups and is a cause for significant morbidity. Recent realization that noninfectious inflammatory causes can predispose to infectious sinusitis has evoked renewed interest in developing and documenting efficacious ancillary therapies that could supplement antibiotic use. Hypertonic saline solution has been shown to increase mucociliary clearance and ciliary beat frequency. Objectives: A double blinded randomized comparative study was undertaken to evaluate the effect of hypertonic saline (3.5%) nasal drops and normal saline (0.9%) nasal drops, to assess the tolerance of hypertonic saline nasal drops and to know if hypertonic nasal drops improve the “quality of life” in patients with chronic sinusitis. Methods: Fifty patients diagnosed as chronic sinusitis in the age group of 18-45 years were randomized into two groups;Group A was treated with normal saline and Group B with 3.5% hypertonic saline for a period of 4 weeks. Pre and Post treatment x-rays of the paranasal sinuses (Water’s view) were graded and radiological scores were given accordingly. The symptoms were evaluated before and after treatment using visual analogue score. Patients were queried about tolerance to the nasal solution and scores were given. Conclusion: Hypertonic saline nasal solution is more efficacious than normal saline solution in the treatment of patients with chronic sinusitis. Hypertonic saline nasal solution was well tolerated and it improved quality of life in these patients. 展开更多

This research was conducted to explore the feasibility of Ji Desheng Snake Pills combined with hypertonic glucose external application in the treatment of stage III and IV pressure injuries. <strong>Methods:</strong> Patients with stage III and IV pressure injuries, who received treatment in our hospital between December 2018 and December 2019 were selected and divided into experimental group, conventional treatment group, and control group, 30 cases for each. The three groups received Ji Desheng Snake Pills combined with hypertonic glucose external application, moist dressing external application and surgical dressing change, respectively. The safety, therapeutic effect and cost benefit of the three treatment methods were compared. <strong>Results:</strong> There were no adverse reactions in the three groups of patients. The PUSH scores of the experimental group and the conventional treatment group were significantly lower than that of the control group on the 14<sup>th</sup>, 21<sup>th</sup>, and 28<sup>th</sup> days, and the result was statistically significant (p < 0.05), while there was no significant difference between the experimental group and the conventional treatment group (p > 0.05). The wound healing rates of the experimental group (70.14 ± 8.27%) and the conventional treatment group (73.99 ± 7.15%) were significantly higher than that of the control group (43.25 ± 8.53%) on the 28<sup>th</sup> day, with statistical significance (p < 0.05);there was no significant difference between the experimental group and the conventional treatment group (p > 0.05). The total treatment costs of the three groups were 569.73 ± 78.12 yuan, 1043.40 ± 135.31 yuan, and 186.47 ± 30.29 yuan. The cost of the conventional treatment group was the highest, followed by the experimental group, and the control group was the lowest. The result was statistically significant (p < 0.05). <strong>Conclusion:</strong> In the treatment of stage III and IV pressure injuries, there was no significant difference in the safety and therapeutic effect between the experimental group (Ji Desheng Snake Pills combined with hypertonic glucose external application) and the conventional treatment group (moist dressing external application), but the experimental group had better cost benefit. 展开更多
