ABSTRACT
Objective To investigate the impact of the initial fluid resuscitation with different ratio of crystalloid and colloid on the prognosis of patients with moderate severe acute pancreatitis (MSAP).Methods A retrospective analysis was made by reviewing the clinical data of 72 patients with the diagnosis of MSAP from January 2015 to July 2017 in Shanghai Changhai Hospital.According to crystalloid-colloid ratio,which was the total volume of crystalloid fluid versus colloid fluid in the first 7d at admission,patients were randomly divided into low crystalloid-colloid ratio group (＜ 4.5),middle crystalloid-colloid ratio group (4.5-7.5),and high crystalloid-colloid ratio group (＞ 7.5).The parameters of the fluid resuscitation,the cases progressing into severe acute pancreatitis (SAP),the incidence of multiple organs dysfunction syndrome (MODS) and mechanical ventilation,pancreatic necrosis and infection rate,30-day mortality,the duration of systemic inflammatory response syndrome(SIRS) and the time reaching full amount of enteral nutrition were analyzed.Results There was no statistically significant difference in gender,age,etiology and APACHE Ⅱ score within 24 h at admission in each group,which were comparable.Within the first 7 d,there were no statistic difference in the total volume of fluid infusion and the speed of resuscitation in the three groups.While the total fluid volume in the first 24 h and 72 h [(3 095 ± 1 253) ml vs (2 524 ± 751) ml,(8 005 ± 7 269) ml vs (6 667 ± 1 498)ml],the total volume of crystalloid fluid in the first 7 d [(14 485 ± 3 917) ml vs (11 544 ±2 639) ml],crystalloid-colloid ratio (12.7 ± 4.9 vs 6.0 ± 1.0),the cases of SAP (12 vs 4),MODS (41.7 ％vs 16.0％) in high ratio group were significantly higher than those in middle ratio group,but the total volume of colloid fluid was significantly lower [(996 ± 528) ml vs (1 968 ± 574) ml].In addition,the duration of SIRS [(16.5 ± 15.2) d vs (8.2 ± 6.4) d],and the time reaching full amount of enteral nutrition [(7.2 ±3.6) d vs (4.8 ± 2.4) d] in high crystalloid-colloid ratio group were higher than those in middle crystalloid-colloid ratio group (all P ＜ 0.05).Comparing with middle crystalloid-colloid ratio group,there were no significant difference in the mechanical ventilation rate,pancreatic necrosis and infection rate and 30-day mortality in high ratio group.The total volume of colloid fluid was significantly higher [(3 680 ± 1 310) vs (1 968 ±574)] and the crystalloid-colloid ratio was significantly lower [(3.2 ±0.9) vs (6.0 ± 1.0)] in low ratio group than that in middle ratio group,and there were no statistical differences on other parameters.Conclusions For the patients with MSAP,early fluid resuscitation with the crystatloid-colloid ratio of (4.5-7.5) can decrease the incidence of SAP and MODS,shorten the duration of SIRS,and promote the recovery of intestinal mucosal barrier function.
ABSTRACT
Diabetic peripheral neuropathy is one of the microvascular complications of diabetes. traditional Chinese medicine (TCM) attributed it to theXiaoke disease andBizheng, with the views ofLuo disease and its TCM patterns differentiation. Based on the treatment for deficiency,Tongluo drugs were added and they made good curative effect. Recently the TCM researches on it have been deepened in the etiology, pathogenesis, treatment, experimental and clinical research, which showed some new under standings. Thus, this paper summarized the relevant researches.
ABSTRACT
To study the determination method of cholesterol in human serum by Coulometric titration. METHODS: The titration was carried out in an electrolytic solution containing 1 mol.L-1 potassium bromide and glacial acetic acid (1∶3). Bromine was electrogenerated at the anode and cholesterol reacted with bromine with a value of reactional electrons (n) as 2. RESULTS: The ranges of recovery for 0.115 mg to 0.459 mg of cholesterol were from 93.9% to 105%, and the average recovery was 100.3%. The relative standard deviation in all applied analysis was less than 1.5%. The accuracy of the method was also assessed in comparison with the results obtained by the enzymatic method used clinically. CONCLUSION: The method proposed is simple, rapid and accurate, and is suitable for the determination of cholesterol in human serum samples.
ABSTRACT
This paper reports the biological characteristics of a group of anti-humanfibrinogen monoclonal antibody(McAb),termed HIF series,prepared in ourlaboratory.Results showed that some HIF McAbs reacted to human fibrino-gen and its fragments specifically no cross-reaction with human serum(1:5),bovin fibrinogen,rabbit plasma and serum was found expcept for HIF-4which expressed cross-reaction with rabbit plasma. A part of HIF McAbs(HIF-2,4,10)appeared precipitation band on immunodiffusion and immunoelectrophoresis test.It is possible that some HIF McAbsmight recognize multiple antigen determinats.Therefor,HIF series includeddiverse specificity of anti-fibrinogen. Some of HIF McAbs inhibited coagulation of blood,clot retraction and pla-telet aggregation.It is possible that the polymerization of fibrin monomer andthe bridge-binding action of plateles were inhibited by HIF McAbs,So thatHIF McAbs may be used to prevent high coagulation and thrombosis.
