ABSTRACT
In the recent clinical guidelines dealing with laboratory tests for liver disease evaluation, the American College of Gastroenterology (ACG) recommends ALT upper reference limits of 33 U/L for males and 25 U/L for females, and individuals with results above these "normal" cutoffs should be further investigated. Considering the differences between laboratory assays measuring ALT in our country, the uniform ACG "normal" range may not be suitable for Chinese population. On the other hand, reference upper/lower limits should not be equated with clinical decision thresholds. Simply acting in accordance with the reference range from ACG guidelines for ALT may lead to overdiagnosis and unnecessary follow-up examinations.
ABSTRACT
In the recent American clinical guidelines dealing with laboratory tests for evaluation of liver disease, the American College of Gastroenterology (ACG) recommends ALT upper reference limits of 33 U/L for males and 25 U/L for females respectively, and that individuals with ALT above these"normal"cutoffs should be further investigated. Considering the differences between laboratory assays measuring ALT in our country, the standardization of methods and the consistency of results can not be completely ensured. The uniform "normal"range of ALT recommended by the ACG guidelines is largely based on findings from foreign studies and may not be suitable to Chinese population. On the other hand, reference upper/lower limits should not simply be equated with clinical decision thresholds. However, due to improper application of the related concepts of the above medical laboratory issues, simply recommending the uniform reference range of the ALT may lead to overdiagnosis and unnecessary follow-up examinations.
ABSTRACT
Objective To evaluate the clinical efficacy of dragon-tiger contending needling at Xi-cleft points plus electroacupuncture in treating postherpetic neuralgia (PHN).Method Seventy PHN patients were randomized into a treatment group of 36 cases and a control group of 34 cases. The treatment group was intervened by dragon-tiger contending needling at Xi-cleft points plus electroacupuncture, while the control group was treated with electroacupuncture alone. In the 4-week treatment, the Visual Analogue Scale (VAS) scores right before and after the 1st, 2nd, 6th, 9th and 12th treatment sessions were recorded, “the maximum pain intensity since the last treatment session” and “real-time analgesic effect” were observed, and the total therapeutic efficacy was also evaluated.Result The real-time analgesic effects right after the 1st, 2nd and 6th treatments in the treatment group were significantly better than those in the control group (P<0.05). The “maximum pain intensities since the last treatment session” prior to the 2nd, 6th, 9th, and 12th treatment sessions were significantly different from the pain intensity before the intervention in the two groups (P<0.05). The “maximum pain intensities since the last treatment session” prior to the 6th, 9th, and 12th treatment sessions were significantly different from those in the control group (P<0.05). The total effective rate and recovery plus markedly-effective rate were respectively 97.2% and 77.8% in the treatment group, versus 91.2% and 59.2% in the control group. There was a statistically significant difference in the recovery plus markedly-effective rate between the two groups (P<0.05).Conclusion Dragon-tiger contending needling at Xi-cleft points plus electro- acupuncture is an effective approach in treating PHN; it acts efficiently and can produce a satisfactory real-time analgesic effect.
ABSTRACT
The present paper puts forward that the relationship between differentiation of syndromes and differentiation of diseases ought to be the relation between methods and results. Differentiation of syndromes must presuppose differentiation of diseases. Syndrome has own specificity only when existence of diseases. However, this disease is not the traditional "disease" named by symptoms, but must be a "new" disease with developing law, specific syndromes and syndromes of corresponding stages.
