Objective To explore the influence of different relaxation training time on relaxation effect of patients with coronary heart disease. Methods 108 patients with coronary heart disease were randomly divided into the morning group, the night group and the morning-night group, each group adopted morning, night and morning-night relaxation training. The relaxation effect was compared between these groups. Results Significant difference existed in sleep quality, anxiety condition and hypnotic dose of the patients in these groups. The time factor played a significant role in the effect of relaxation. The morning group was different in sleep quality improvement and anxiety condition alleviation from the night group and the morning-night group. Conclusions Relaxation training at night or morning-night could effec-tively help improve the sleep quality of patients, decreasing the level of anxiety and tendency of hypnotic in pa-tients with coronary heart disease.

Objective To evaluate the treatment effect of later course accelerated hyperfractionated radiotherapy with chemotherapy for stage Ⅲ and ⅣA nasopharyngeal carcinoma. Methods 116 patients with stage Ⅲand Ⅳ s nasopharyngeat carcinoma were randomly divided into three groups: the conventional fractionation radiotherapy(CFR, 38 cases), the concurrent radiochemotherapy group(CCRT, 39 cases) and the later course accelerated hyperfractionated radiotherapy combined with chemotherapy group (LCAF+CT, 39cases). CFR group was treated with 60Co γ rays and X rays. When the patients had received the dose of 36～38 Gy through composite faciocervical fields, changed into preauricular fields, the total dose was 70 ～75 Gy.And the total dose of cervical metastasis lymph nodes were 70～80 Gy. CCRT group was treated with DDP and 5-Fu. LCAF+CT group was treated with accelerated hyperfractionated radiotherapy. When the dose of composite faciocervical fields had reached 36～38 Gy, changed the fields and treated with accelerated hyperfractionated radiotherapy, 1.3 Gy/fraction, twice daily. The total dose was 69.8～75 Gy. And the chemotherapy drugs was similar to CCRT group. Results The positive response rate among LCAF+CT, CCRT and CFR groups were 94.9 %, 89.7 %, 76.3 % respectively. The complete response rate in the nasopharyn of LCAF+CT group was higher than CFR group(P ＜0.05). The local control rates of one, two and three year of three groups were 100 %, 97.4 %, 89.5 %, 94.9 %, 84.6 %, 68.4 % and 89.7 %, 74.4 %, 57.9 %respectively; and the survival rates of one, two and three year of three groups were 100 %, 92.3 %, 84.2 %;89.7 %, 84.6 %, 71.0 % and 79.5%, 76.9 %, 57.9 % respectively. There were obvious difference between LCAF+CT and CCRT groups in local control rate and survival rate. But there were no difference between LCAF+CT group and CCRTgroup, and also between CCRT group and CFR group. Conclusion The later course accelerated hyperfraetionated radiotherapy combined with chemotherapy can promote disappearance of primary lesion and improve the local control rate and survival rate of patients with stage Ⅲand ⅣA nasopharyngeal carcinoma.

ObjectiveTo evaluate the parenteral nutrition formula's character of all-in-one-mixed preparation and pre-mixed preparation applied for hospitalized patients in China.MethodsWe collected parenteral nutrition (PN) prescriptions in hospitalized patients with various diseases at dispensing centers of 6 hospitals in different areas of China. Statistic analysis was made by nutrients application, total liquid, nonprotein calories, total nitrogen, ratio of non-protein calories and total nitrogen, and ratio of glucose and fat. A comparison was made between all-in-one-mixed and pre-mixed preparation as to all the indices.Results The nutrients supply in all-in-one-mixed PN preparation, as well as in the pre-mixed PN preparations of 3 different energy degrees can meet the basic nutrition requirements of most patients. The total nitrogen supply in all-in-one-mixed PN prescriptions meets nutrition requirements in most patients, but the ratio of non-protein calories and total nitrogen[( 180-250) : 1]and the ratio of glucose and fat (0. 56-1.26)were significantly different from what a doctor would recommend[( 100-150) : 1, 1.0]. While the ratios in the pre-mixed PN preparation on 3 different energy degrees are more consistent with recommeded values,which are at 167 and 0. 8 respectively.ConclusionsAll-in-one-mixed and pre-mixed PN preparation have their own individual advantages and limits, and both of them can meet the requirements of most hospitalized patients. More attention should be paid to the nutrients proportion when doctors prescribe all-in-one-mixed PN preparations.
