Lesion was made individually to the various cortical areas in 14 rats.The cortico- fugal fibers terminating into cochlear nuclei were traced in sections by means of the modified Nauta and Fink-Heimer silver staining method.The results were as follows: 1.After damaging the auditory area or somato-sensory area 1(SI)of the cerebral cortex unilaterally,degenerating fibers were found bilaterally in the ventral and dorsal cochlear nuclei.This result showed that the above cortical areas have direct descending connection with the cochlear nuclei. 2.No degenerating fibers were found in the cochlear nuclei after the ablation of the motor or visual area of the cerebral cortex,which demonstrated that the cochlear nuclei do not receive descending fibers from the above cortical areas. 3.The pathway from the cerebral cortex to the cochlear nuclei was:The descending fibers which originated from the auditory area or SI area ipsilaterally passed through the capsula interna and basis pedunculi,and part of these fibers passed dorsally and downward to the lateral portion of the reticular formation of the midbrain;and from there the fibers passed through the lemniscus lateralis and dorsal acustic stria to the cochlear nuclei of the ipsilateral side.The cochlear nuclei in contralateral side also received the corticofugal fibers by way of the dorsal acustic stria.These fibers might cross to the contralateral side at the region in the posterior commissure,superior colliculus commissure and inferior colliculus commissure.

Microcapsule technology recently has been applicated and developed in pharmaceutical,chemical,food and so on.The achievments have been obtained on the novel technics of microcapsulation,analytical methods of microcapsule characteristics,and methods of characterization for the appearance and porous structures of microcapsules.The novel developments on the structure and property of microcapsules were reviewed.

Objective To explore the efficacy,safety and life quality of patients of morphine hydrochloride sustained-release tablets combined with celecoxib in the treatment of advanced lung cancer with moderate to severe cancer-induced pain.Methods A total of 247 patients of advanced lung cancer with moderate to severe cancer-induced pain were randomly divided into combination therapy group (n =127) and morphine monotherapy group (n =120) using simple random sampling digital table method.The differences of dose,efficacy,adverse drug reactions and life quality between the two groups were analyzed.Results In achieving similar analgesic effect,the average maintenance dose of morphine in combination therapy group was (52.51 ±19.92)mg/d,lower than that in monotherapy group [(58.75 ±20.64)mg/d,t =-2.414,P =0.017].The incidence of constipation in combination therapy group was 34.6％,lower than that in monotherapy treatment group (47.5 ％,x2 =4.218,P =0.040).The life quality of the two groups were improved,and the life quality improvement rate in combination therapy group was 59.8％,higher than that in monotherapy treatment group (43.3％,x2 =6.736,P =0.009).Conclusion Morphine hydrochloride sustained-release tablets combined with celecoxib is effective in the treatment of moderate to severe cancer pain,which can reduce the dosage of morphine and reduce adverse reaction,so as to improve the life quality of the patients with advanced lung cancer.
