Objective To investigate the effect of nursing interventions on the quality of life after radiotherapy in nasopharyngeal cancer. Methods 56 patients with nasopharyngeal cancer who received radiotherapy were randomly divided into control group and intervention group. All the patients were given conventional nursing interventions, and those in the intervention group were given accurate evaluation, enhanced psychological guide, reasonable dietary guide, and special nursing for preventing and treating complications. All the patients were evaluated by using quality of life questionnaire core 30 items(QOL-C30). Results The scores of the dimensions of somatic function,psychological function, social function and material life after interventions in the intervention group were significantly higher than those in the control group (P＜0.05 ). Conclusion Nursing interventions can improve the quality of life, and the therapy can be completed smoothly.

OBJECTIVE:To study the safety of percutaneous administration of Hongzhi gutong cataplasm. METHODS:Rab-bits were taken for single dose in complete skin irritation test(n=4),single dose in damaged skin irritation test(n=4)and multi-ple doses in complete skin irritation test(n=4). The left and right sides of the skin respectively paste 3 cm×3 cm blank matrix and Hongzhi gutong cataplasm for 24 h(calculated by crude drug of 0.14 g). After removing tape 1,24,48,72 h,the erythema and edema in hair removal site of rabbits in the former 2 tests were observed;after 24 h of administration,the rabbits in the last group were administrated again after exposing the administration area for 1 h,repeated 3 times,the erythema and edema in hair removal site after removing tape the first,second time and 1,24,48,72 h in the third time were respectively observed. RESULTS:In the 3 experiments,the scores of erythema and edema of all rabbits were 0,and skin irritation was evaluated as no irritation. CONCLU-SIONS:Hongzhi gutong cataplasm has no skin irritation in rabbits.

Objective To observe the pathologic changes of corneal lesions in rabbits induced by mustard gas and changes of lymphocytes in the pathologic development so as to discuss the role of lymphocytes in the pathogenic process.Methods Thirty-five New Zealand white rabbits were randomly divided into experiment group and control group according to the random number table.In experiment group,rabbits were exposed to 0.2 ml of mustard gas liquid (400 μl/L) for a period of 4 minutes and were divided into 6 subgroups at 15 min,2 h,1 w,3 w,4 w,and 8 w after injury.Corneal tissue from each group was collected to detect changes of lymphocytes with aid of HE and immunohistochemical stainings.Results In experiment group,corneal epithelium was dropped totally,basement membrane was exposed,swelling was thickened,matrix layer was loosened and swelled,and collagen fibre was ranged loosely at 15 minutes and two hours ; corneal epithelium appeared multi-layer hyperplastic change in acute restoration period at 1 week; basal corneal epithelium cells appeared irregular column arrangement in chronic inflammation period at 3 and 4 weeks; around 10％ of toxic corneas had delayed reaction with partial corneal epithelium resloughed,fundus membrane appeared,edema thickened,and stroma collagens loosened and swelled at eight weeks.Immunohistochemical Envision staining showed positive expression of plymphomonocytes (CD20,CD45RO,and LCA) inside matrix layer at corneoscleral junction.Conclusions Ocular exposure to 400 μ/L mustard gas for a period of four minutes leads to direct and delayed lesions to cornea,which presents at one week and eight weeks respectively.The lymphocyte-mediated cellular and humoral immunity responses may be involved in the pathogenic process.

With polyethylene glycol vitamin E succinate (TPGS) as the carrier materials, and berberine hydrochloride ( BER) as model drug, we formed berberine hydrochloride (BER) -loaded TPGS nanomicells (BER-PMs) using filming-rehydration method to improve its solubility and in vitro anti-tumor effect. The transmission electron microscope (TEM) was used to observe the particle appearance; particle detector was used to detect the diameter and Zeta potential; and ultracentrifugation was utilized to determine the encapsulation efficiency (EE) and drug-loading (DD); dynamic dialysis method was used to study the in vitro release behavior of BER-PMs, and the anti-tumor activity against MCF-7 cells was determined by MTT method. Results showed that the average particle size of BER-PMs was (12.45 ± 1.46) nm; particle size was uniform and spherical; drug loading and encapsulation efficiency were (5.7 ± 0.22)% and (95.67 ± 5.35)%, respectively. Zeta potential was (-1.12 ± 0.23) mV; release rate within 24 h was 37.20% and 41.14% respectively in pH 7.4 and pH 6.5 phosphate buffer in vitro; compared with BER, BER-PMs can significantly inhibit MCF-7 cell proliferation (P < 0.05), promote cell apoptosis and improve the anti-tumor activity of BER in vitro. Therefore, the formed berberine hydrochloride micelle can more effectively promote the apoptosis of MCF-7 cell, and improve the drug's in vitro anti-tumor effect.
