Point-of-care testing (POCT) of blood glucose has been widely used for continuous monitoring of glucose in clinic due to high sensitivity, convenience, accessibility and shorter TAT.It has been developed rapidly in recent years. But glucose POCT is often out of control and management from central laboratory and usually it was performed by non-laboratorians.It becomes the growing concerns that how to avoid the discrepancy between POCT results and central laboratory results, how to ensure POCT quality of each batch of blood glucose results, how to solve issues in the application and ensure that patients' results are accurate and reliable. The hospital should put the POCT management under the whole management system and improve the accuracy of POCT to achieve the complete quality assurance. This article introduced the management program experiences of glucose POCT in Huashan hospital according to the JCI accreditation and CAP-LAP.

Objective To observe the metabolism characters of plasma glucagon-like peptide 1 (GLP-1) in surgical critical ill patients.Methods Totally 64 selective surgical patients were prospectively enrolled and randomly divided into two groups:enteral nutrition (EN) group (50％ glucose 100 ml orally administered or through nasogastric tube on the next day after operation) and parenteral nutrition (PN) group (50％ glucose 100 ml intravenously infused on the next day after operation).Blood glucose and plasma GLP-1 were determined before operation,after operation,and 0 min,30 min,90 min,and 180 min after the 50％ glucose was used.Then,the EN group was divided into stress hyperglycemia (SH) subgroup and non-stress hyperglycemia (non-SH) subgroup.In both subgroups,plasma tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected before operation,after operation,and the next day after operation.Blood glucose,plasma insulin,C-peptide,and GLP-1 were measured before operation,after operation,and 0 min,30 min,90 min,and 180 min after 50％ glucose was used.Results The plasma GLP-1 level (pmol/L) of EN group increased significantly after 50％ glucose was used,and reached the peak at the time of 30 min.In contrast,it did not change in PN group,and were significantly lower than EN group at the time of 30 min [(5.69 ± 2.92) pmol/L vs (33.52 ± 12.32) pmol/L,P ＜0.01] and 90 min [(5.71 ±2.14) pmol/L vs (15.92 ±6.63) pmol/L,P =0.00].Plasma insulin level in SH subgroup were significantly higher than in non-SH group after operation [(18.17±6.18) mU/Lvs (12.10±3.60) mU/L,P=0.01] and30 min [(56.02±14.78) mU/Lvs (43.39±15.60) mU/L,P=0.03] and 90min [(114.58±25.11) mU/Lvs (90.45±25.91) mU/L,P=0.03] after 50％ glucose was used.Plasma C-peptide level in SH subgroup was also significantly higher at the time of 30min [(6.86 ±1.15) μg/L vs (4.76 ± 1.06) μg/L,P=0.04] and 90 min[(12.17 ± 1.96) μg/L vs (9.81 ± 2.35) μg/L,P =0.03] after 50％ glucose was used when compared with non-SH subgroup.Plasma GLP-1 level in SH subgroup was significantly lower than in non-SH group at the time of 30 min [28.76 ± 9.61) pmol/L vs (37.36 ± 10.51) pmol/L,P =0.03] and 90 min [(13.49±4.26) pmol/Lvs (17.33±5.57) pmoL/L,P=0.04] after 50％ glucose was used.Conclusions Early post-operative PN increases plasma GLP-1 level and reduces the SH incidence.In SH patients,endogenous insulin expression increases while plasma GLP-1 level decreases.Post-surgery inflammatory reaction may result in low plasma GLP-1 level and high blood glucose level.

Objective To explore the effect of recombinant pEGFP-N3-APC vectors carrying various APC functional domains on the expression of β-catenin in human colorectal cancer cells HT-29.Methods The recombinant plasmids were transfected into HT-29 cells mediated by lipofectamine~(TM) 2000, and detected by green fluorescence and RT-PCR. Western blot was applied to detect β-catenin expression level in HT-29 cells after transfection, and gray scales of electrophoresis strips were analyzed by SPSS 13.0.Results Green fluorescence and RT-PCR made clear that all 5 recombinant plasmids were successfully expressed in HT-29 cells. Western blot showed that β-catenin expression level in HT-29 cells was not affected after being transfected with pEGFP-N3-APC1, pEGFP-N3-APC2 and pEGFP-N3-APC3, and was distinctly affected after being transfected with pEGFP-N3-APC4 and pEGFP-N3-APC5, especially the later one. Conclusion The selected APC5 gene fragment with 15-amino acid repeats and SAMP repeats, which is relatively short, can degrade β-catenin level in HT-29 cells and may be applied in the gene therapy.

Cardiovascular disease, with high morbidity and mortality, has been threatening the health of human beings. Therefore, expecting to find a more effective therapeutic method, a plenty of researchers devote themselves to the study of the cardiovascular disease all the time. Since discovered on the heart, M3 receptor of muscarinic acetylcholine receptor (mAchR, M receptor) became a new starting point of the research of the cardiovascular disease. With more and more investigation, many people found that M3 receptor could protect the heart from kinds of cardiovascular disease, which may make it a new hopeful therapeutic point. So, expecting to give support to the reference and encouragement for the study of disease related to M3 receptor in future, this review expounds M3 receptor on the heart from the main following aspects: the effect on the heart, the influence on the cardiovascular disease and the mechanism of M3 receptor involved.

Objective To investigate the effect on electrical restitution of β1-adrenergic receptor antagonist esmolol administered during cardiopulmonary resuscitation in the porcine ventricular fibrillation model. Method Ventricular fibrillation untreated for four minutes was induced by dynamic steady state pacing protocol in 40 healthy male pigs, in which local unipolar electrograms were recorded using one 10-electrode catheter that was sutured to the left ventrieular epicarditan. During CPR, animals were randomized into two groups to receive saline as placebo or esmolol after two standards doses of epinephrine. At postresuscitation 2-hour, six pigs were randomly selected from each group and the second VF induction was performed. Local activation-recovery intervals (ARI) restitutions and the VF inducibility between control group and esmolol group were compared. Western blotting was performed to determine cardiac ryanodine receptor (RyR2) protein expression, and their phosphorylation status. Results No sig-nificant differences were observed at the restoration of spontaneous circulation between two groups. Higher postre-suseitation 2-hour survival rate was observed in the esmolol group. Esmolol significantly flattened ARI restitution slope, lessened regional difference of ARI restitution, decreased the VF inducibility, and alleviated RyR2 hyper-phosphorylation. Conclusions Esmolol given during CPR significantly improved postresuscitation 2-hour survival rate. Its effects on modulating electrical restitution property and intracellular calcium handling make up the most important reasons why β1-blockade significantly reduced the onset and maintenance of VF.

Objective To develop a method for rapid and accurate detection and identification of bacterial pathogens directly from body fluid specimens and to evaluate its application in clinical laboratory.Methods Bacteria DNA was extracted from 205 body fluid specimens with column-based kit,and the high variable V1 and V3 regions of bacterial 16S rRNA gene were amplified with broad-range primers.Amplicons were analyzed by pyrosequencing and the generated sequences were searched in the bacterial identification database.Traditional culture-biochemical method was also used for these specimens and the results were taken as the golden standard.SPSS 11.0 was used to calculate the sensitivity,specificity,false positive/negative rate,positive/negative predictive value and positive/negative likelihood rate of pyrosequencing method.Results The positive rate of bacteria culture was 39.5％ (81/205),among which 71 were infected with single bacterium,and 10 were infected with two species of bacteria.Compared with the culture identification results,pyrosequencing had a 100.0％ (71/71) concordance when applied to detect and identify bacterial pathogens from specimens with single specie bacterium infected.To specimens with two species bacteria infected,7 out of 10 specimens were in concordance with the culture identification results.Besides,pyrosequencing detected 10 positive specimens and identified bacterial pathogens infected in the 124 culture-negative specimens.Taken bacteria culture as the standard method,the sensitivity of pyrosequencing for identifying bacterial pathogen in body fluid was 100.0％,and with a specificity of 91.9％,the false positive rate was 8.1％,the false negative rate was 0.0％,the positive predictive value was 89.0％,the negative predictive value was 100.0％,and the positive and the negative likelihood rate were 12.4 and 0,respectively.Conclusion Pyrosequencing can be used to detect and identify bacterial pathogens directly from body fluid specimens with the advantages of rapidity,high sensitivity,high accuracy and high throughput.

ObjectiveTo review the etiology and classification of cholangiectasia. MethodThe clinical data of 1098 patients with cholangiectasia treated from January 2000 to December 2009 were retrospectively analyzed. Results For the 1098 patients, 69 patients (6.3％) had congenital choledochal cyst, and 1029 patients (93.7％) had secondary cholangiectasia which were secondary to 22 diseases, The top 5 of the etiological diseases were bile duct stones (366 patients, 33.3 ％), pancreatic head carcinoma (137 patients, 12.5％), peri-ampullary carcinoma (122 patients, 11.1％), cholangiocarcinoma (68 patients,6.2％),and chronic pancreatitis or pancreatic head cyst (62 patients,5.6 ％).
