In the 7th report of International Committee on prevention, detection, evaluation and treatment of hypertension has collected all studies from 1997 to 2003. Classification of hypertension: prehypertension, prehypertension in stage, prehypertension in 2 stage. It is better to use stethoscope for measure blood presure. Content of checking hypertension patients: find out the reason for hypertension, calcutate BMI, hear blood pulse in neck, stomach, groin, examination of nerve system, ECG, urine test and blood test. Treatments: control life style, diuretic, block /beta, block Ca channel, block /alpha, educate for patients

BACKGROUND: Nowadays, although its clinical value remains controversial institutions utilize hair mineral analysis. Arguments about the reliability of hair mineral analysis persist, and there have been evaluations of commercial laboratories performing hair mineral analysis. OBJECTIVE: The objective of this study was to assess the reliability of intra-laboratory and inter-laboratory data at three commercial laboratories conducting hair mineral analysis, compared to serum mineral analysis. METHODS: Two divided hair samples taken from near the scalp were submitted for analysis at the same time, to all laboratories, from one healthy volunteer. Each laboratory sent a report consisting of quantitative results and their interpretation of health implications. Differences among intra-laboratory and interlaboratory data were analyzed using SPSS version 12.0 (SPSS Inc., USA). RESULTS: All the laboratories used identical methods for quantitative analysis, and they generated consistent numerical results according to Friedman analysis of variance. However, the normal reference ranges of each laboratory varied. As such, each laboratory interpreted the patient's health differently. On intra-laboratory data, Wilcoxon analysis suggested they generated relatively coherent data, but laboratory B could not in one element, so its reliability was doubtful. In comparison with the blood test, laboratory C generated identical results, but not laboratory A and B. CONCLUSION: Hair mineral analysis has its limitations, considering the reliability of inter and intra laboratory analysis comparing with blood analysis. As such, clinicians should be cautious when applying hair mineral analysis as an ancillary tool. Each laboratory included in this study requires continuous refinement from now on for inducing standardized normal reference levels.

As there is justification showing that Poiseuille's Law is not suited for vertical Capillary tube viscometer, Poiseuille's Law has not been used to deduce the calculation formula for measuring liquid viscosity by means of vertical Capillary tube viscometer; it can only be used to deduce the calculation formula for measuring liquid viscosity by horizontal capillary tube viscometer. In this article, we explained the extension of Poiseuille's Law to deduce the Calculation formula for measuring liquid viscosity by using shallow pool and deep pool Capillar tube viscometer, and so corrected the mistakes in using Poiseuille's Law for a long time.

In cases of sero-negative rheumatoid arthritis (RA), no abnormal findings are observed on blood tests and its clinical course is favorable, compared to sero-positive RA. In the acute phase of sero-negative RA, infiltration of neutrophils may be the only pathologic finding on frozen section biopsy. Thus, it might be misdiagnosed as pyogenic arthritis. We report on a case of acute sero-negative RA misdiagnosed as pyogenic arthritis during hip surgery with review of the literature.

BACKGROUND: We aimed to evaluate the performance of the CLINITEK Novus urine chemistry analyzer (Siemens, UK). METHODS: The precision, correlation, and carryover study were performed using two kinds of commercial quality control materials and 40-55 freshly collected patient specimens. We calculated exact and within-1-block agreement, along with kappa agreement, to compare the semi-quantitative results between urine chemistry analyzers. The urine specific gravity taken by a refractometer was compared with the analyzer results. Moreover, we analyzed additional urine specimens for protein to evaluate the agreement of results between those of the CLINITEK Novus and the AU680 analyzers (Beckman Coulter, Japan). RESULTS: The precision study showed acceptable results; within-1-block agreement was 100% in all tested items. The urine chemistry results from the CLNITEK Novus analyzer demonstrated ≥85.1% within-1-block agreements with those of the Uriscan Super, and the kappa test results were ≥0.81. The comparison of specific gravity with manual refractometer showed a good correlation (r=0.991), and the protein comparison with the AU680 analyzer also showed a good correlation (with exact and within-1-block agreements being 75.9% and 100.0%, respectively). The carryover rates were 0% in all tested items, except specific gravity and heavy blood tests. CONCLUSIONS: The CLINITEK Novus analyzer showed good performance in terms of precision, comparison, and carryover in this study. Therefore, the CLINITEK Novus automated urine analysis is expected to be useful for routine urinalysis in a clinical laboratory.
