Impacts of albumin synergized with hydroxyethyl starch on early microvascular albumin leakage after major abdominal surgery in rabbits

Abstract Purpose: To investigate the impacts of albumin synergized with hydroxyethyl starch (HES) on early microvascular albumin leakage after major abdominal surgery in rabbits. Methods: Forty male Japanese rabbits were randomly divided into four groups: the control group, the saline group, the albumin group, and the Syn group (hydroxyethyl starch+albumin). The latter three groups were performed gastrectomy plus resection of pancreatic body and tail and splenectomy. The serum albumin concentration was detected before and 48h after surgery, and the conditions of mesenteric microvascular leakage in these 4 groups were observed under microscope 48 h after surgery to calculate the leakage rate. Results: Compared with the saline group, the albumin group and the Syn group exhibited significantly increased serum albumin concentrations 48h after surgery (P<0.05). The albumin leakage rate was the most obvious in the albumin group, followed by the saline group, while that in the Syn group was the minimal, and there existed significant differences among these groups (P<0.05) . Conclusion: Simple administration of albumin in the early stage after major abdominal surgery could increase the albumin leakage, while the synergization of albumin and hydroxyethyl starch could reduce the albumin leakage.

Systematic review of the association of diuretics with falls in the elderly / 中华护理杂志

Objective To systematically evaluate the association of diuretics with falls in the elderly. Methods Data of case-control studies and cohort studies of diuretics with falls in the elderly were collected by searching eleven electronic databases:MEDLINE,Embase,CENTRAL,AMED,CINAHL,Web of Science,Wiley online library, CBM,CNKI,VIP and WanFang Data from inception to July 2017. Study quality was assessed by the NOS scale. Meta-analysis was conducted by RevMan 5.3 software. Results A total of 17 studies involving 78284 patients were included(seven case-control studies and ten cohort studies). Meta-analysis showed that:①Case-control studies:crude OR showed that diuretics would not increase the risk of falls in elderly patients [OR=0.95,95%CI (0.66,1.38),P=0.80];adjusted OR showed that diuretics would increase the risk of falls in elderly patients[adjusted OR=1.25,95%CI (1.15,1.36),P<0.05]. ②Cohort studies:crude OR showed that diuretics would increase the risk of falls in elderly patients[OR=1.16,95%CI(1.02,1.32),P=0.03];adjusted OR showed that diuretics would not increase the risk of falls in elderly patients[adjusted OR=1.06,95%CI(0.92,1.22),P=0.43]. ③There was no statistically sig-nificant difference in the risk of falls among the elderly at different places,and there was no significant difference in the risk of falls among various diuretics (P>0.05). Conclusion Based on meta-analysis results of cohort studies that controlled confounders,and the results of diuretics in different places and different kinds,diuretics will not in-crease the risk of falls in older adults. Due to limited quantity and quality of included studies,the results need to be further confirmed by more rigorous clinical trials in the future.

Laboratory Evaluation of Bone Marrow Metastasis: Single Institute Study / 대한진단검사의학회지

BACKGROUND: The incidence of bone marrow (BM) metastasis might be related with the occurrence of malignant tumors in ethnic groups. So, we investigated the type and the frequency of metastatic tumors of BM and analyzed the clinicopathologic variables of BM metastasis. METHODS: This study included 932 cases of primary malignant tumor which were requested for BM study from January 1995 to June 2006 in Chonnam National University Hospital and Chonnam National University Hwasun Hospital. Peripheral blood smears (PBS); aspirates, touch prints, and trephine biopsies of BM; and medical records including other laboratory test results were reviewed. RESULTS: Overall frequency of BM metastasis was 11.9% (111/932). Primary tumors with BM involvement in children comprised neuroblastoma (74.1%), rhabdomyosarcoma (7.4%), and malignant lymphoma (7.4%). For adult patients, they consisted of malignant lymphoma (56.0%), gastrointestinal cancer (20.2%), and lung cancer (6.0%). In the case of malignant lymphoma, diffuse large cell lymphoma was the most frequent one. Laboratory findings of patients with BM metastasis commonly showed anemia and thrombocytopenia; in addition, serum LD, ALP, AST and ALT were elevated in 81.5% (75/92), 63.4% (59/93), 63.5% (61/96) and 33.3% (32/96), respectively. Leukoerythroblastosis was observed only in 19.8% (22/111) on PBS examination. CONCLUSIONS: The most common non-hematopoietic metastatic tumor was neuroblastoma in children and gastrointestinal tumors in adults. Leukoerythroblastosis, anemia, and the elevation of serum LD, ALP, and AST were useful markers for the prediction of BM metastasis.
