ABSTRACT
Objective:To explore the early diagnostic value of serum procalcitonin(PCT),C-reactive protein (CRP) and endotoxin in patients with sepsis caused by bacterial bloodstream infection.Methods:Retrospectively analyzed 123 cases of patients diagnosed with sepsis induced by bacterial bloodstream infection in our hospital from May 2010 to May 2015,detected their serum PCT,CRP and endotoxin levels,and analyzed the evaluation value of these three indexes for sepsis induced by bacterial bloodstream infection by receiver-operating characteristic curve (ROC).Results:Blood sample culture results showed that 123 cases of bacterial bloodstream infections caused by sepsis patients in the presence of infection of G+bacteria were 35 cases,G-bacteria infection of 88 cases;The levels of three index in the G+bacteria group were significantly lower than that in the G-bacteria group (P＜0.05);The serum PCT,CRP and endotoxin levels was positive correlated with each other among G+bacteria group,G-bacteria group and all bacteria group;ROC curves showed that the cutoff value of serum PCT,CRP and endotoxin for diagnosis of patients with sepsis induced by G+bacteria bloodstream infection were 1.58 μg/L,95.25 mg/L and 16.71ng/L,and their sensitivity and specificity were (65.92％,88.37％),(67.39％,84.38％) and (56.34％,78.93％) respectively;and the cutoff value for diagnosis of patients with sepsis induced by G-bacteria bloodstream infection were 2.45 μg/L,79.45 mg/L and 15.54 ng/L,their sensitivity and specificity were (78.73％,97.13％),(68.89％,92.38％) and (65.39％,95.33％)respectively.Conclusion:Detecting the serum PCT,CRP and endotoxin levels is helpful to identify patients with sepsis induced by G+ or G-bacteria bloodstream infection,with high sensitivity and specificity,which can be used in the early diagnosis of sepsis induced by bacterial bloodstream infection.
ABSTRACT
Objective To explore the mechanism of Didang Qigui Recipe on preventing diabetes. Methods Ten female rats were set randomly as normal group, and others 70 were injected with STZ (60 mg/kg) to establish the diabetic model. After the model was established, 50 model rats were randomly divided into five groups:the model group, Didang Qigui Recipe group, the gliclazide group, Didang Qigui Recipe high-dose group, Didang Qigui Recipe and gliclazide group, with 10 rats in each group. All groups were given a gavage with related medicine. With treatment being given respectively, eight weeks later, contents of IL-1βand IL–2 in serum were detected by ELISA and structure of pancreatic β cells was observed by immunohistochemistry and microscope. Results Compared with the model group, the contents of IL-1βand IL-2 in serum of rats decreased in treatment groups, especially in Didang Qigui Recipe group and Didang Qigui and gliclazide group (P<0.05). The degree of apoptosis in pancreaticβcells, especially in the above two groups, has been less affected than other groups (P<0.05). Conclusion Didang Qigui Recipe has preventive and therapeutic effects on diabetes by inhibition of inflammatory response and protection structure of pancreaticβcells.
ABSTRACT
In recent years, the literature showed that Yiqi Yangyin and Huoxue Huayu method (benefiting qi and nourishing yin, promoting blood circulation to remove blood stasis) in treating diabetic complications has achieved a satisfactory effect. This article made a summary on the method of Yiqi Yangyin and Huoxue Huayu from theoretical, clinical, and laboratory aspects.
ABSTRACT
Objective To evaluate the blond-saving effect of low central venous pressure(CVP) combined with acute hypervolemic hemedilution(AHHD)in patients undergoing hepatic lobectomy.Methods sixty ASA I orⅡpatients of both sexes aged 32-48 yr weighing 47-72 kg undergoing hepatic lobectomy for primary malignant hepatonm under epidural combined with general anesthesia were randomly divided into 3 groups(n=20 each);group I control(C);group 1I AHHD and group Ⅲ low CVP+AHHD.Group C received crystalloid and coloid in a ratio of 1.5:1 during operation.In groupⅡ4% suecinylated gelatin was infused at 50 ml·kg-1·h-1 for 30 min after tracheal intubation (AHHD);while inⅢ group low CVP was induced and maintained by epidural administration of a mixture of 1.5% lidnoaine +O.2% bupivacaine 6-8 ml combined with intravenous infmion of propofol at 6 mg·kg-1·h-1 until 10 min after hepatic lobectomy was completed.then 4% succinylated gelatin was infused at 50 ml·kg-1·h-1 for 30 min.Blood glucose,Hb,Hct, WBC count,blood coagulation (PT,AVIT,Fib),shtmic-pyruvic transaminase (GPT) and renal function (BUN,Cr) were determined before operation (baseline),immediately before skin incision,immediately before and 10 min after liver lobe was removed,at the end of operation and 7 d after operation.Urine output,intraoperative blood loss and blood transfusion and complications were recorded.Results The glood glucose concentration.WBC count and GPT levd were significantly lower;the amount of fluid infused and urinary output before hepatic lobe resection and the percentage of the patients with allogeneic blood transfusion during operation were less;Hb,Hct and the amounl of fluid infused and urinary output after hepatic lobe resection were uigher in grolp Ⅲ than in group I and ⅡⅡⅡ.There were no significant differences in blood coagulation,renal function,the total amount of fluid infused and urine output among the 3 groups.No patient developed any complication.Conclusion The low CVP hefor combined with AHHD after hepatic resection can decrease intraoperative blood loss and allogeneic blood transfusior and is safe.
