Changes in the way new drugs are tested appear to be necessary. Three changes are presented here and will be discussed. The first change is that Alzheimer's disease must be considered a disease of four major pathological processes, not one. The four processes are: 1) vascular hy- poperfusion of the brain with associated mitochondrial dysfunction, 2) destructive protein inclusions, 3) uncontrolled oxidative stress, and 4) proinflammatory immune processes second- ary to microglial and astrocytic dysfunction in the brain. The second change recommended is to alter the standard cognitive measurement tools used to quantify mental decline in test patients. Specifically the Dementia Severity Rating Scale (DSRS) should supersede Mini-Mental State Examination (MMSE) and other popular tests, and a measurement scale developed in research should be used to produce a linear and non-irregular baseline. Finally, accepting the concept that four etiologies cause Alzheimer's disease leads to the last necessary change, that new thera- pies must be employed directed against all four causes, likely as a combination. There are drugs ready to be employed in such a combinations which are available and used clinically for other purposes so can be used "offlabel" and one such combination is suggested.展开更多

OBJECTIVE: To establish a method for evaluating the therapeutic effects on anti-epileptic drugs using changes of interval and duration of seizure. DESIGN: A prospective cohort study. SETTING: Zhumadian Psychiatric Hospital. PARTICIPANTS: Outpatients and inpatients suffering from epilepsy attending firstly visited Zhumadian Psychiatric Hospital from June 2001 to June 2002 were enrolled. They were diagnosed as epileptic according to the International Classification of Epileptic Seizure by International League Against Epilepsy (1981) based on the clinical history, physical examination, and investigations. The interval time was no more than 6 months. Informed consent was obtained from all the subjects, and the study was approved by the hospital ethical committee. METHODS: ① For the first visit and each follow-up, the following data were recorded, including general demographic information, seizure type, the date and time of ictus, the duration of ictus, and inducement or situation related, according to which the following indexes could be calculated, including seizure styles, interval, duration, cluster frequency and cluster duration. The information from the first review was noted as annals A. The second interview was taken at the end of the evaluating period; the information from the second review was noted as annals B. The third interview was taken within two weeks after the second one; the information from the third review was noted as annals C. The annals B or the annals C were respectively compared with the annals A in the light of the same types or the same styles of the same patient. Summation of the scores of interval change and duration change of the same type or the same style and 5 of basic score was the score of a corresponding seizure type or a corresponding style of one patient. In order to test its reliability and validity, the score of change of frequency or duration plus 5 scores respectively was the score of frequency or duration. ② Reliability and validity were tested by calculating corresponding correlation coefficient with SPSS 11.0. ROC curve was used for developing diagnostic criterion of predicting therapeutic effects with SPSS 11.0. MAIN OUTCOME MEASURES: ① Reliability and validity; ② Diagnostic criterion for predicting therapeutic effects one year later. RESULTS: Totally 28 patients were involved in the final analysis of results. ① Reliability and validity were high:rinter-rater=0.98, rtest-retest=0.99, rconstruct validity=0.83. ② A total score 〉 6 was the optimal diagnostic criteria for predicting therapeutic effects one year later, in other words, a patient who scored more than 6 at the evaluating period may be seizure-free one year later. CONCLUSION: It is a potential tool for evaluating epileptic therapeutic outcome, and it can be diffusely used in interrelated fields after being further validated.展开更多

Acupuncture was applied at the 5 acupuncture points, Jingqu(LU 8), Zutonggu(BL 66), Yanggu(SI 5), Yangchi(TE 4), and Zhongwan(CV 12) for 2 weeks with 4 sessions. We assessed the effect of Korean Saam acupuncture on the immune system in cancer patients by measuring particular blood cell subsets, including CD3 +,CD4+, CD8+, CD19+, and CD56+ cells, as well as total white blood cell count, absolute neutrophil count, and fatigue score. The measurement was performed before and after acupuncture and at a 2-week follow-up.RESULTS: There was a statistically significant increase in the number of CD3+(P=0.023) and CD8+ cells(P<0.001) and T-cell subsets, as well as a decrease in the fatigue severity scale(FSS) score(P=0.001) after Saam acupuncture using the 5 acupoints.CONCLUSION: Acupuncture may improve the immune system by increasing the counts of a few immune cells and relieve fatigue in cancer patients by decreasing FSS scores. Although this was a non-controlled study, it constitutes preliminary research investigating the potential effects of Saam acupuncture in increasing the counts of several immune cells in cancer patients.展开更多

Methods: The enrolled patients were randomized into a TCM group (31 cases) treated with Qufeng Zhidong Recipe and a Western medicine group (30 cases) treated with haloperidol and trihexyphenidyl. Two courses of treatment were observed with 12 weeks as one course. The therapeutic effect and adverse reaction were assessed with Yale Global Tic Severity Scale (YGTSS), Tic Symptom Score Scale (TSSS), TCM Syndrome Score Scale (TCMSSS), Treatment Emergent Symptom Scale (TESS) and laboratory examinations. Results: The total effective rate was 100% in the TCM group and 60% in the Western medicine group with statistical significance in difference (P<0.05). All the scores in the TCM group were better than those in the Western medicine group (P<0.05). Conclusion: Qufeng Zhidong Recipe can obviously relieve the symptoms and signs of TD children without toxic side-effects.展开更多
