BACKGROUND: Parameters of platelet can reflect functions of coagulation. Granule membrane protein-140 (GMP-140), which is also called P-Selectin, in α-granules of platelets can reflect activities of platelet. Dysfunction of blood sugar and blood lipid in diabetic patients can result in complications such as thrombotic diseases.OBJECTIVE: To analyze the variation regulation of the platelet parameters and GMP-140 in patients with type 2 diabetes mellitus.DESIGN: A case-control study.SETTING:Department of Clinical Laboratory and Department of Endocrinology, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.PARTICIPANTS: From March to April 2005, forty-five patients with type 2 diabetes mellitus, who were treated at the Department of Endocrinology,Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology, were enrolled as diabetic group, and 45 healthy people, who were checked with health examination at the same period,were selected as control group. They all joined the experiment voluntarily. METHODS: Changes of quantity of blood platelet, mean platelet volume (MPV), platelet distribution width (PDW) and platelett-large cell ratio (PLCR) were analyzed with blood cell counter. GMP-140 was measured by enzyme-linked immunosorbent assay (ELISA), meanwhile, compared with those of the healthy people.MAIN OUTCOME MEASURES: Contents of the parameters of platelets and GMP-140 of subjects in the two group s.RESULTS: A total of 90 cases without drop out, 45 cases in the diabetic group and control group, respectively, were involved in the result analysis.①Comparison of the content of GMP-140 in the two groups: It was significantly higher in the diabetic group than that in the control group [(28.8±10.3) ,(9.1±5.6)μg/L(t=2.37,P ＜ 0.01 )]. ②Comparison of parameters of blood platelet of subjects of the two groups: The MPV, PDW and P-LCR in patients of the diabetic group were markedly higher than those in the control group (t=2.02, 2.02, 2.02, P ＜ 0.01 ), while the blood platelets (PLT)was dramatically lower than that in the control group (t=2.15, P ＜ 0.01 ).CONCLUSION: The MPV, PDW, P-LCR and the content of GMP-140 of patients with type 2 diabetes mellitus significantly increase, while the PLT decreases, which indicate that platelet activity enhances and the consumption of platelet increases in patients with type 2 diabetes mellitus.

Objective To summarize the key point of collaboration during the surgery of endoscopic guided vitrectomy for complicated ocular trauma.Methods From October 2010 to March 2013,a total of 25 cases(25 eyes) of complicated ocular trauma were treated by endoscopic guided vitrectomy.The the key point of collaboration was summarized.Results Surgeries of 25 cases (25 eyes) went smoothly,visual acuity improved,without enucleation cases.Postoperative complications were mainly secondary glaucoma and vitreous hemorrhage,and all were improved after treatment.Conclusions Endoscopic guided vitrectomy for the treatment of complicated ocular trauma is one of the effective means,and the advantage is that the surgery could be done when the refractive medium is opacity.

OBJECTIVE To establish a convenient method for detecting plasmid-mediated AmpC beta-lactamases in Enterobacteriaceae lacking chromosomal AmpC beta-lactamases and to investigqte their genotype.METHODS Fifteen isolates of Klebsiella pneumoniae were collected and the diameters of inhibitory zone of cefoxitin in combination with or without cloxacillin were measured separately by standard disc diffusion test.The M3D assay was used as control method.And the activity of AmpC beta-lactamases of all isolates was simultaneously assayed.Multiplex PCR was performed to determine the genotype of AmpC beta-lactamases.RESULTS Among 15 isolates,8 isolates were identified to have plasmid-mediated AmpC beta-lactamases.The sensitivity and specificity of AmpC beta-lactamases phenotypic confirmatory test were 100%.Eight of 15 isolates were identified to be DHA-1 beta-lactamases by multiplex PCR.CONCLUSIONS The new AmpC beta-lactamases phenotypic confirmatory test is a reliable method for detecting plasmidmediated AmpC beta-lactamases in Enterobacteriaceae lacking chromosomal AmpC beta-lactamases.DHA-1 beta-lactamases are the main genotypes of plasmid-mediated AmpC beta-lactamases in Hubei Province of China.

With the great success of imatinib mesylate(IM) and other tyrosine kinase inhibitor (TKI),chronic myelogenous leukemia (CML) is taken as a successful model of targeted therapies for human cancer.Although the emergence of TKI has greatly improved the prognosis of CML,the long-term TKI treatment may bring the problems of drug resistance,serious side effects,poor compliance,and heavy economic burden.Recently,people focus on whether patients would be cured after discontinuation of TKI treatment.Here,the progresses on discontinuation of TKI therapy in CML presented in the 54th American Society of Hematology (ASH) annual meeting were reviewed.

Objective To study the significance of anti-cyclic citrullinated peptide (anti-CCP),anti keratin antibody (AKA) and anti-RA33 autoantibodies (RA33)in the diagnosis of elderly-onset rheumatoid arthritis (EORA) and to explore the role of the united detection of anti-CCP, AKA and RA33 in the diagnosis of EORA. Methods The above three kinds of autoantibodies were detected in 69 patients with EORA, 73 patients with polymyalgia rheumatica (PMR) and 65 patients with osteoarthritis (OA). The anti-CCP and RA33 were measured by enzyme-linked immunosorbent assay (ELISA),and AKA was measured by indirect immunofluorescence (IIF). Results In the group of patients with EORA, the sensitivity and specificity of anti-CCP were 55.1% and 94.3%, the sensitivity and specificity of AKA were 31.3% and 91.5%, and the sensitivity and specificity of RA33 were 36.2% and 95.4% respectively, which were significantly higher than those in the groups of patients with PMR and OA. United-detection of anti-CCP, AKA and RA33 reduced the sensitivity,hut increased the specificity (100%) with higher positive predictive value. Conclusions Anti-CCP,AKA and anti-RA33 can emerge in the patients with EORA and the anti-CCP displays higher sensitivity and specificity. United detection of anti-CCP, AKA and RA33 can increase the specificity and positive predictive value (100%) and has high value in the diagnosis of EORA.

The changes in shape, structure and function of red blood cells (RBC) after cold storage were observed by using slow cold storage technique. Before and after cold storage, RBC mean corpuscular volume (MCV), RBC fragility (RF), whole blood viscosity (WBV), RBC deformity (RBCD), LFU, SatO2, hematocrit (HCT), RBC recovery rate (RBCRR) and RBC immune function were measured. The result showed that after resuscitation, RBC had vital resistance to hypotonic solution. There was no significant difference in MCV, RBCD and LFU (P>0.05). HCT and WBV were decreased and RBCRR reached 84.1 %(all P<0.01). SatO2 was increased from 30.5 % to 98.2 %. RBC immune function showed no significant difference (P>0.05). It was suggested that quality of RBC didn't change after cold storage and RBC could be cryopreserved for a long time.

Objective To establish a method for the quantitative determination of AGP (Acanthopanax giraldii Harms polysaccharides). Methods AGP content was determined by DNS Method. The absorptions of processed samples were tested at the wavelength of 520 nm. Results Contrast to glucose, the linear range was 46.6～233.0 mg/L (r=0.999 2), the average recovery was 99.0%～102.1%, RSD=3.52%, n=5. The polysaccharides measured in 3 batches of samples were 1.3～1.9 mg/g. Conclusion The method is sensitive,steady with good repeatability, and help to the qulity control of Acanthopanax giraldii Harms.

Most researchers consider that high exposure to heavy metals can result in hemorrhagic gastritis,hepatonecrosis,cancer,even death.There are many routes for heavy metals to get into human body,for instance absorption by gastrointestinal tract,cutaneous absorption etc.In this paper,the author reviewed the recent researches on brain function damage induced by heavy metals via olfactory pathway.Some heavy metals have especial affinity with brain tissue and cause functional disorder and death of nerve cells,and the mechanisms were discussed in detail.
