Objective Investigate the effect of applying clinical pathway on the patients undergoing leiomyoma of uterus. Methods As an experimental group of patients, 50 cases of uterine leiomyoma are treated with clinical pathway. By contrast, another 100 cases are treated with the traditional medical care as control group. Results Waiting time for surgery and hospital stay of the experimental group are less than the control group; and the average hospitalization cost of experimental group is lower than the control group (P< 0.01). Conclusions Application of clinical pathway management will regulate the activities of medical treatment, ensure the quality of health care, improve the feeling of patients, increase efficiency of hospital services, reduce the financial burden of patients, increase the hospital social benefits.

METHODS: The coal miners received questionnaire investigation and their blood pressure, height and weight were measured, plasma renin activity(PRA), plasma angiotensin Ⅱ(AngⅡ) and aldosterone(ALD) were tested by means of radioimmunoassay in coal miners with hypertension and nor-hypertension. RESULTS: It was found that levels of PRA,AngⅡ and ALD were significantly higher in hypertensive group than in nor-hypertensive group(all P

Objective To evaluate the influence of the storing time of venous blood samples on the differential count of WBC by Sysmex XE-2100 hematology analyzer. Methods At room temperature, the precision of the differential count of WBC by Sysmex XE-2100 hematology analyzer were tested. 38 samples were taken the differential count of WBC by Sysmex XE-2100 hematology analyzer after stored for 0, 2, 4, 8, 24 and 48 h. Differential count of WBC was also taken under microscope for comparison. Results The precision of differential count of WBC by Sysmex XE-2100for all the samples was in the allowable range. The correlation coefficient of the differential count of WBC by two methods for neutrophils, lymphocytes, monocytes, eosinophils and basophils were 0.9859, 0.9775, 0.8053, 0.8695and 0.5243 (P<0.01). There was insignificant difference in the test at 8h, very significant difference of MONO and EOS at 48 h. Differences of EOS, MONO between two methods were significant increased at 8 h. Conclusion At room temperature, the differential count of WBC of venous blood samples by Sysmex XE-2100 hematology analyzer should finish within 8 h.

Methods Accurancy: nucleated red blood cells were counted from 38 specimens by Sysmex XE-2100 Hematology Analyzer and compared with the number counted under microscopy. Precision: 3 specimens with different values were counted for the nucleated red blood cells 10 times by Sysmex XE-2100 Hematology Analyzer and compared with the number counted under microscopy. The CV(% ) value was estimated.Results There was insignificant difference between the results obtained from Sysmex XE-2100 Hematology Analyzer and those under microscopy. In the T-test, P >0.05, r=0.9893(P< 0.01).CV(% ) were 8.1% and 15.8% . It means that the Sysmex XE-2100 is more precise in analyzing the nucleated red blood cells than that under microscopy. Conclusion The nucleated red blood cells count by Sysmex XE-2100 is accurate and fast to obtain clinical data.

OBJECTIVETo investigate the effects and mechanisms of Yishen Huoxue decoction (YHD) on chronic renal failure (CRF) rats induced by 5/6 nephrectomy.

METHODSThe glomerulosclerosis model was established by 5/6 nephrectomy in rats. Experimental animals were allocated into the normal group, the model group, the YHD group and the benazepril group. Urine protein of 24 h (UP) at the 6th and 12th weekend after operation, blood urea nitrogen (BUN) and creatinine (SCr), albumin (Alb) and haemoglobin (HB) at the 12th weekend were measured, renal pathology changes were examined with light microscope, the expressions of proliferating cell nuclear antigen (PCNA) and fibronectin (Fn) were examined by immunohistochemistry and mRNA expressions of connective tissue growth factor (CTGF) and plasminogen activator inhibitor-1 (PAI-1) by RT-PCR at the 12th weekend.

RESULTSCompared with those in the normal group, the levels of UP, BUN and SCr, the area of glomerular mesangial matrix, the FN deposition, PCNA expression in glomeruli and tubular interstitium and mRNA expressions of CTGF and PAI-1 were all significantly higher in the model group (P < 0.05). All the above-mentioned indexes were lower in the YHD group than those in the model group (P < 0.05). PCNA positively expressed cells in glomeruli of the normal, model group, YHD group and benazepril group was 7.00 +/- 2.24,34.78 +/- 6.96,15.75 +/- 2.61 and 15.50 +/- 2.57 respectively, positively correlated to the expression of CTGF, PAI-1, FN and SCr level.

CONCLUSIONYHD could delay the progression of CRF in 5/6 nephrectomized rats, and the mechanisms were mainly related to the inhibition on renal cell proliferation and it induced over-expression of cytokines, and accumulation of extracellular matrix.

Objective:To retrospectively analyze the routine clinical laboratory parameters for hepatocellular carcinoma,in an attempt to search for parameters for diagnosis of hepatocellular carcinoma(HCC).Methods:The pre-operation clinical labo- ratory data,such as tumor makers,and serological biochemical indices,hepatitis B virus(HBV)infection markers,and HBV DNA titers,were collected from 828 patients who were pathologically diagnosed as having HCC;then the correlation between these data with tumor size and the pathological grades of HCC was analyzed.Results:It was found that 97.9% of the 828 pa- tients were infected with HBV and 70.9% of them were accompanied by liver fibrosis.We also found that the tumor size was correlated with albumin(ALB),globulin(GLB),A/G,aspartate aminotransferase(AST),ratio of aspartate to alanine amin- otransferase(AST/ALT),gamma-glutamyl transferase(GGT),alkaline phosphatase(ALP),alpha-L-fucosidase(AFU),al- pha-fetoprotein(AFP)and tumor grades;meanwhile,the pathological grades of tumor was correlated to prealbumin(PALB), GGT and tumor size(all P

Objective To detect the differential expression genes(DEGs)between Barrettg esophagus(BE)and normal esophagus with oligomicroarray,and to explore the target genes related to the development of BE.Methods The total RNAs of matched BE and normal esophagus mucosa from saIne patient were isolated with one step Trizol method.Matched RNAs were qualified with 10g/L agarose gel electrophoresis.After tRNA purification,cRNAs were synthesized and labeled with fluorescence.which were tIlen hybridized with Agilent oligomicroarray containing 30,968 probes.The fluorescence intensity features were detected by Agilent scanner and quantified by software Feature Extraction.Results On average,2 biopsies by disposable jumbo biopsy forceps provided approximately 5μg RNA required for microarray.The total RNA,reverse transcription product and fluorescence labeled cRNA were all of high quality.Among 2-fold DEGs,there were 142 up-regulated genes and 284 down-regulated genes including 15 bel-2 related genes such as bel-2,MCL1,BAX,BIK and BCLAF1 Conclusion Microarray-based studies are feasible in endoscopically obtained tissues.The development of BE is a complicated process involving multi-genes,in which abnormal expression of bel-2 family related genes might be involved,but the exact mechanism needs further research.

Objective To establish the methods for quantitating the circulating tumor DNA with PicoGreen fluorescent nucleic acid stain and investigate the role of the quantitative analysis in diagnosis of breast cancer. Methods Circulating tumor DNA was isolated from serum with QIAmp blood kit and was quantitated by spectrofluorometry with PicoGreen fluorescent stain. Receiver operator characteristic ( ROC) curve and area under the curve were used to estimate the role of DNA quantification in diagnosis of breast cancer. Results The efficiency of QIAamp blood kit isolating DNA from serum was 37. 8%-46. 2%, average 43. 4%. Circulating tumor DNA concentration as low as 1 ng could be detected by PicoGreen spectrofluorometry. and the detected range was 1-500 ng/0. 2 ml. The median concentration of serum DNA in breast cancer group was (169. 70+ 124. 10) μg/L, and that of healthy control and breast benign group were (54. 30±36. 84) μg/L and (51. 70±29. 04) μg/L, respectively (P<0. 01). The area under the ROC curve was 0. 899 (95% CI: 0.848-0.951), and the sensitivity was 78. 2%, the specificity was 90% by using the cutoff value of 96. 0 ng/ml. Conclusions The concentration of circulating tumor DNA can be efficiently quantitated by PicoGreen spectrofluorometry, which indicates the potential of clinical applicability in breast cancer diagnosis.
