International Journal of Laboratory Medicine 2009;30(9):848-849,851
Objective To explore the applicable value of microcolumn gel immunoassay(MGIA) in transfusion-related experiments(blood typing, cross matching, antibody titration), and carry out its methodical evaluation. Methods Fifteen anti-Rh D positive samples from 55 Rh D negative patients, twenty-one cases of discrepant blood typing and twenty-nine cross matching positive samples were studied by applying MGIA and routine tube test simultaneously. Antibody titer data from 853 pregnant women with type O were brought into statistics. Results In 55 Rh D negative samples, the positive rate of Rh D antibody tested by MGIA and tube test was 27.27%(15/55) and 21.82 % (12/55) respec-tively,and the samples with titer 1:4 above got the coincident results by the two methods. For twen-ty-one discrepant blood typing samples, 11 cases with weak reaction showed discrepant results by MGIA;however, all samples showed weak reaction by tube test. In 29 samples with cross matching positive by MGIA,2 cases were confirmed to be negative by tube test. For the pregnant women with type O,IgG antibody titer abnormal ratio was 33.18%(144/434) if their respective husbands was with type A,33.17%(139/419) if their respective husbands was with type B.Conclusion MGIA is charac-teristic of convenience, fastness and reliability of test results, but its false-positive or false-negative should be paid attention to. When abnormal results occur, traditional tube test as well asmicroscopic examination should be performed in parallel.

Extramedullary plasmacytoma (EMP) are often located in the head and neck region, commonly affecting the nasal cavity, tonsillar fossa and oral cavity but rarely the retropharyngeal space. In this report, a 60-year-old woman with large EMP in the retropharyngeal space is presented, who was diagnosed by pathology, bone marrow aspirate and computed tomography scan. The patient received operation and postoperative radiotherapy with dose of 50 Gy. At sixteen months follow-up, the patient was doing well with no signs of recurrence.

Purpose:To explore the possibility of non-sent inel lymph node (NSN) metastases in early breast carcinoma patients with positi ve sentinel lymph node (SLN) and its clinical significance. Methods:The incidence and related clinical factors of NSN metas tases were analyzed in 84 early breast carcinoma patients with positive sentinel lymph node, who underwent radical mastectomy. Results:The metastatic NSN was identified in 41 of the 84 pati ents with positive sentinel lymph node (48.8%), the incidence of NSN metastases was related to primary tumor size, SLN metastatic focus size and HER-2 expressi on status, the incidence rate of NSN metastases is proportional to the size of t he primary tumor and metastatic SLN focus, patients with positive HER-2 expres sion have a high NSN metastases rate. Conclusions:The early breast carcinoma patients with

Objective To evaluate special diagnosis and treatment of occult breast cancer. MethodsDiagnostic means used included breast roentgenography,selective mammary ductography, fine needle aspiration and excision biopsy in 28 cases. ResultsBreast roentgenography detected 4 cases ( 7/16), selective mammary ductography identified 4 cases(4/6). The definite diagnosis rate by lump biopsy and immunohistochemistry was 10 cases (10/13). Postoperative follow-up was abtained in 18 cases,with 5 dying of recurrence or distant metastases. Among them 4 patients underwent only axillary node excision. Conclusion Nipple discharge,localized thickening the gland are very important clue to the diagnosis of occult breast cancer.Lump biopsy and immunohistochemistry is a mainstay for the final establishment of the diagnosis of breast cancer. Radical or modified radical mastectomy with adjuvant radiotherapy and chemotherapy is a suitable treatment modality for occult breast cancer.

Diabetic vascular disease is a major complication of diabetes, which is characterized by the formation of collateral vessels of serious damage to systemic disease. Substantial evidence have shown that timpaired endothelial progenitor cell function, non-enzymatic glycation end products accumulate, and Wnt signaling pathway dysfunction may be an important mechanism of impaired angiogenesis after the diabeticlimb ischemic. This paper is to make a study of its mechanism, and to provides a new strategy for diabetes therapeutic angiogenesis.

Objective To develop and validate a simple and reliable HPLC method for the analysis of flee and total carnitine in human serum and to investigate its clinical significance. Methods After proteins in serum were precipitated with a precipitating reagent, carnitine in serum was derivatized to form its ester. HPLC separation of the sample solution was performed on a Lichrospher SiO2 column and detected by ultraviolet absorbance at 260 nm. A mobile phase composed of acetonitrile-citric acid-triethanolamine was found to be the most suitable for this separation at a flow rate of 1.2 ml/min and enabled the baseline separation of the carnitine from interferences with isocratic elution. The free and total carnitine levels in serum were studied in 347 subjects. Results Under the chromatographic conditions described, the carnitine derivative had a retention time of approximately 10 min. Good separation and detectability of carnitine in human serum sample were obtained. The method proved to be linear in the range of carnitine from 0 μmol/L to 400 μmol/L The relative standard deviations of within-assay ( n = 5 ) for free and total carnitine analysis were 3.36% and 1.97% , respectively, and between-assay (n =7) for free and total carnitine analysis were 3.04% and 1.77%, respectively. The average recovery was 98. 2% for free camitine and 96.3% for total carnitine, respectively. The average L-carnitine concentrations in the 347 subjects were as follows: total carnitine (52. 2 ± 8. 6 ) μmol/L, free carnitine ( 42. 3 ± 8. 3 ) μmol/L and acylcarnitine ( 9. 9 ± 2. 9 )μmol/L in the male group ( n = 182), and total carnitine (48.2 ± 9. 9 ) μmol/L, free camitine ( 37.9 ±8. 7) μmol/L and acylcarnitine ( 10. 3 ± 3.5 ) μmol/L in the female group ( n = 165 ). Statistical analysis showed that total and free carnitine levels of male were higher than that of female ( P <0. 01 ) while there was not statistical difference of acylcarnitine levels between two groups ( P > 0. 05). Conclusion The method has been successfully applied to the simultaneous determination of free and total carnitine in serum with good sensitivity, specificity and repeatability, and this is a useful guidance for the clinic therapy and the mechanism study on the diseases associated with carnitine.

Objective: Carnitine,the only carrier for the fatty acid crossing into mitochondria for oxidization,has a significant effect on the metabolism serum lipids.The purpose of this study is to investigate the effects of different doses of carnitine supplement on serum lipids in hyperlipemia rabbits. Methods: Twenty-eight rabbits were equally randomized into a control and three experimental groups,the former fed on high-fat diet,and the latter on carnitine at the dose of 100,200 and 400 mg/kg respectively every day in addition to high-fat diet.Blood samples were collected from the central artery of the rabbits for the measurement of the total cholesterol(TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),apolipoprotein B(ApoB) and free carnitine in the serum,their body weight obtained at 0,1,2,3,4 and 5 weeks,and the effects of different doses of carnitine supplement were observed on serum lipids.Results: All the 28 rabbits were included in the result analysis.The hyperlipemia model was successfully established after 4 weeks of high-fat diet.Compared with the control group,the experimental groups showed a remarkable decrease in the levels of TC,TG,LDL-C and AapoB and an increase in that of HDL-C in the serum,positively correlated with the dose and time of carnitine supplement.With the lengthening of time,the effects of different doses of carnitine supplement on the serum lipids was gradually decreased.Conclusion: Carnitine supplement can inhibit the increase of the levels of TC,TG,LDL-C and AapoB in the serum of the rabbits with hyperlipemia induced by high-fat diet and the effect is positively correlated with the dose and time of carnitine supplement.
