Objective To describe the experience of nurses in combined care program of traditional Chinese medicine (TCM) and provide references for nursing managers. Methods The phenomenology research method was adopted in this study. Fourteen nurses who had achieved the combined care program of TCM participated in an in-depth interview. Data were analyzed by using phenomenological analysis. Results All nurses approved nursing program of TCM: finding sense of belonging in nursing work;demonstration of self-value;standardization of nursing tednnique;harmonious environmont of nursing work. But some defect still existed: too subjective evaluation item of nursing program of TCM;inappropriate evaluation table;lact of hospital characteristics of TCM nursing;deficiency of TCM knowledge. Conclusion Nursing managers should pay more attention to nurses' emotional experience, grasp the implementation of the problems during the program and improve the program, optimize the skills, provide trainings.

Cadmium targets on kidney and bone and results in many toxic effects. Disturbance of calcium metabolism is one of the important aspects of cadmium toxicity, which includes reduced intestinal calcium absorption, increased urinary calcium excretion, negative calcium balance, development of osteomalacia and osteoporosis. There exists two potential mechanism of influence of cadmium on calcium metabolism. One is the direct inhibition of cadmium on active transports of calcium. The other is the indirect influence on calcium metabolism due to reduced renal synthesis of 1,25-dihydroxycholesterol induced by cadmium. Further research should focus on revealing how cadmium directly inhibits calcium entering into cells and transporting by calcium binding protein, elucidating whether renal synthesis of 1,25-dihydroxycholesterol is reduced in low-level cadmium exposure population, and also on clarifying the molecular biological mechanism of effects of cadmium on calcium metabolism.

Apoptosis is important to the development of diseases. Research recently indicates that c-Jun N-terminal kinase (JNK) and cysteinyl aspartate-specific protease (caspase) play key roles in apoptosis and affect the development of diseases. This article is to introduce the function and relationship between JNK and caspase in apoptosis during the process of diseases.

After the HRP solution was injected into gastric wall of the Beijing Duck, the afferent neurons of the stomach were retrogradely traced. The results arc as follows: 1.The afferent sympathetic neurons from the proventriculus distribute in T_1-L_1 spinal ganglia, concentrically in T_(1-6), the peak number is in T_3. 2.The afferent neurons of the vagus from the proventriculus arc present in the nodosal and jugular ganglia. After HRP was injected into the ventral muscle of the proventriculus, most of the labelled neurons were found in the jugular ganglia. 3.From the gizzard, the afferent sympathetic neurons localize in T_1-L_1 spinal ganglia. The muscle tenium craniodorsalis is concentrated in T,_6, the peak number in T_3. The remained parts of the gizzard are concentrated in T_(2-6), the peak number in T_4. 4.The afferent neurons were retrogradely traced in the nodosal ganglia after HRP was injected into each part of the ventricul. But in the jugular ganglia labelled cells were found only in the region of the muscle tenuim craniodorsalis of the gizzard.
