RESUMO
Comrade LU Zhi-jun, a famous surgeon and acupuncture expert, was a leading cadre in health field with outstanding achievements, and a leader of western medicine doctors learning traditional Chinese medicine in the Chinese Communist Party, and also he was a main establisher of The China Academy of Chinese Medical Sciences and a founder of TCM scientific researches and integrated Chinese and western medicine in new China. The present paper reviews the course of LU Zhi-jun in learning and applying acupuncture and moxibustion therapy and a part of works carried out in faithfully implementing our party's policies for uniting Chinese and Western medicine, and in development of TCM including acupuncture and moxibustion in past tens years.

We have used electron microscopy to measure quantitatively the morphology of electrical synapses in a circuit that has been proposed to account for the positional discrimination of the leech. Injection of a presynaptic nociceptive sensory neuron and the postsynaptic anterior pagoda neuron with HRP showed gap junctions in the neuropil. After double labeling, La(3+)-treated ganglia revealed labeled gap junctions from 2.0 to 3.5 nm wide. Between the labeled axon terminals, there were innexons with diameters of 8 to 10 nm. The innexon's central pore diameter was 2 nm, and the mean of the center-to-center distance between two innexons was 30 nm. Except for the gap junction areas of nociceptive sensory neuron axon terminals, the other ultrastructural parameters measured by freeze fracture were similar to those of samples labeled with HRP and filled with La(3+). These data suggested that the gap width, innexon diameter, and its central pore do not on their own account for the mechanism of positional discrimination, which may depend rather on the differences in distribution and number of gap junctions.
