Abstract
After the study of the valvular distribution of 18 cadaveric great saphenous veins, we performed microsurgically great saphenous veno-valvulectomy and primary in situ veno-arteriolization for 18 severely ischemic limbs of 17 patients of these patients, 14 had thromboangiitis obliterans, and 3 arteriosclerosis. 16 patients were followed up for 14 to 32 months after operations. The results were excellent. The procedure is a good alternative for the treatment of extensive arterial occlusive disease of the lower limbs.

Abstract
Sequence-tagged sites (STSs) are short stretches of DNA that can be specifically detected by the polymerase chain reaction (PCR) and can be used to construct long-range physical maps of chromosomal DNA. These STSs can be detected by PCR assays developed by reference to data obtained from the sequencing of restriction fragment length polymorphism-DNA markers for chromosome 21, which were derived from recombinant lamba-phage and plasmid clones made from DNA of a human-hamster hybrid cell line. In this report, we describe the generation of 19 new STSs that are specific for human chromosome 21.

Abstract
Fourteen CSM patients with clinical findings of myelopathy had their diagnoses proved with MRI imaging and at operation. There were a control group of 28 normal subjects for MEP and another control group of 32 for SEP. The results of the study showed that 72.7% had MEP abnormality with prolongation of the central motor conduction time (CMCT) in 7 cases and absence of motor action potentials after C7 stimulation in one of the 11 patients. In 2 patients with prolongation of CMCT, normal SEPs were found in the same arm while 1 patient showed directly a reversal of the results. The short-term follow-up study in 10 patients showed normalization of the prolonged CMCT in one and reappearance of motor action potentials with C7 stimulation in another. The authors considered that the non-invasive and painless, transcranial magnetic stimulation of the motor pathways might be useful in the assessment and management of CSM patients and better than the electrical stimulation.

Abstract
Based on the method of assessing the growing age of trees by "annual ring in the bark", the active ingredients magnolol and honokiol in 3 species Houpo (Magnolia officinalis, M. biloba, M. rostrata) of different ages, were determined by HPLC. The results present a reference for defining the reasonable period of collection and quality evaluation of Houpo.

Abstract
Crude extracts of Scutellia baicalensis and a particular low molecular weight substance known as Baicalin were shown to inhibit HIV antigen expression in H9 cell culture, with 50% inhibitory doses of 0.6 microgram/ml and 3.3 micrograms/ml, respectively. They also inhibited P24 antigen production in H9 cells, with IC50's of 1.94 and 4.74 micrograms/ml, respectively. Cytoxicity was tested in H9 and HUT78 cells: Both exhibited relatively low levels of cytoxicity. These results indicated that S. baicalensis and Baicalin strongly inhibit HIV replication in cell culture.

Abstract
343 cases of motor neurone disease (MND) were examined with electromyography. The result showed EMG examination was of much vale in helping to ascertain an accurate diagnosis which clinically could be made in only about 1/4 of the series of cases. The ages of onset ranged from 4 months to 10 years with an average of 36.8 years. 56.8% under 40 years. There was a higher male preponderance, the male/female ratio being 3.2:1. It was 1.6:1 in a report from a western country. 123 cases showed only one limb involvement clinically while the EMG findings were also abnormal in the other three limbs. Fibrillation potentials were found to be at more than two sites in one muscle in 84.5% in this series, where as they occurred in 95-100% of the infantile and juvenile cases. Abundant fibrillation potentials were found in 37.1% of the cases within 3 years after the onset and in 13.6% in those with a longer duration. The increment of the mean duration of motor unit potential was 94.5% and that of the mean amplitude 91%. It seemed not necessary to emphasize giant potentials. The motor nerve conduction velocities (NCV) were normal in 95% while the sensory NCV were almost always normal (98%). All of the 3 cases tested with single fiber EMG showed an increment of jitter of 95-100% and a muscle fiber density of 2.95-3.65.

Abstract
Thirty-three chinese medicinal herbs reputed by ancient chinese folklore to have anti-infective properties were extracted. The extracts and their compounds were tested for inhibitory activity against the human immunodeficiency virus RT in vitro. 8 of the 33 extracts were found to be active. Of these, MBAA9045 was studied in greater depth. We found that it was a noncompetitive inhibitor against HIV-RT. The concentration of MBAA9045 reducing HIV-RT activity by 50% (IC50) was 22 mumol/L. Chinese medicinal herbs appear to be a rich source of potentially useful materials for the treatment of human immunodeficiency virus infection.
