Objective To provide the nurse care evidence of nutritional intervention in patients with lung cancer during radiotherapy and chemotherapy by analyzing the nutritional status of these patients.Methods 55 patients with lung cancer who received chemotherapy and radiotherapy were selected.The nutritional status of these patients were evaluated by laboratory examination data at the time of hospitalized,ongoing and the end of radiotherapy. Results The hemoglobin(Hb),albumin(ALB),body mass and body mass index(BMI)were (130.50 ±17.80)g/L, (41.02 ±5.68)g/L,(61.29 ±8.75)kg,(22.36 ±2.78)kg/m2 respectively at admission;(115.90 ±19.00)g/L, (37.94 ±5.55)g/L,(59.95 ±9.05 )kg,(21.86 ±2.86)kg/m2 respectively during the course of radiotherapy;(110.40 ±19.40)g/L,(36.91 ±5.30)g/L,(58.91 ±9.30)kg,(21.48 ±2.99)kg/m2 respectively at the end of radiotherapy.At different stages of radiotherapy,the nutritional index gradually decreased,the Hb was lower in the middle of the radiotherapy than on admission,the difference was significant(t =8.611,P <0.05).The Hb in the late stage of radiotherapy was lower than the middle,the difference was significant(t =2.492,P <0.05).Although the ALB in the latter stage of radiotherapy was lower than the middle,but the difference was not statistically significant (t =1.464,P >0.05),and the difference was significant compared with on admission(t =4.815,P <0.05).The weight of the patients in the middle period of radiotherapy was less than the time of admission,but the difference was not statistically significant(t =0.781,P >0.05).The weight of patients in the late stage of radiotherapy was lower than the medium term,but the difference was not statistically significant as well(t =0.601,P >0.05),and there was no significant difference compared with on admission(t =1.382,P >0.05).The BMI of the patients with radiotherapy was lower than that at the time of admission,the difference was not statistically significant(t =0.091,P >0.05).The BMI of patients with radiotherapy was lower than that in the medium term,whereas the difference was not statistically significant(t =0.690,P >0.05),and the difference was not statistically significant compared with on admission(t =1.599,P >0.05).The Hb (F =16.643,P =0.000)and ALB(F =7.736,P =0.001)decreased significantly in particular.Conclusion The risk of malnutrition in patients with lung cancer is exist during radiotherapy and chemo-therapy,and it is obvious in the middle -late stage,the changes of physical and biochemical indexes have been appeared,and among them,Hb and ALB are the most obvious,so should be monitored and managed cause these data varied significantly.

Objective To study causes of deterioration of sudden mydriasis in craniocerebral trauma patients with normal intracranial pressure and verify the efficiency of specific treatments.Methods A retrospective analysis was performed on causes of four cases of accidental mydriasis in normal intracranial pressure among 473 cases of craniocerebral trauma treated from June 2008 to March 2012.Changes of patients' condition and monitoring indices were observed after specific treatments.Results Abnormal mydriasis with synchronously normal intracranial pressure was largely due to sufficient decompression after a certain period of intracranial hypertension and persistence of brain perfusion pressure to more than 110 mm Hg or due to high cerebral perfusion pressure caused by redundant drainage of cerebrospinal fluid or low intracranial pressure (＜ 10 mm Hg),together with factors like low plasma osmotic pressure and carbon dioxide accumulation.The study showed that the intracranial pressure was maintained normal,that the brain swelling took a turn for better,that medical condition were stabilized and that pupil returned to normal in the four cases after treatment with specific protocol.GOS was four points in three cases and five points in one during follow-up at six months postoperatively.Conclusion Incidence of mydriasis with normal intracranial pressure in craniocerebral trauma patients can be efficiently declined through reduction of peripheral blood pressure,perfusion pressure controlling,hypertonic remedy maintenance and brain edema relief.

Objective:To detect the correlativity between clinical periodental indexes and C-terminal telopeptides of type I collagen (CTX)concentration in gingival crevicular fluid(GCF).Methods:77 teeth with periodontitis in 60 patients from the international Bethune peace hospital were included.The concentration of CTX in GCF was detected by enzyme-linked immunosorbent assay.The plague indexe(PL),gingival indexe(GI),probing depth(PD)and attachment loss (AL)level were recorded at clinic.The correla-tion of CTX concentration and clinic indexes was analysed by Kruskal-Wallis test using SPSS 1 1 .0 software.Results:The Spearman correlation coefficient of PL,GI,PD and AL with CTX was 0.386(P <0.01 ),0.366(P <0.05),0.382(P <0.05)and 0.31 4(P <0.05)respectively.Conclusion:PL,GI,PD and AL are positively correlated with the concentration of CTX in GCF(P <0.05).

AIM: To confirm the effects of capillary endothelium injury in the lung with ischemia reperfusion. METHODS: The rabbits pulmonary models of ischemia reperfusion (I-R)injury were established. Plasma nitric oxide and endothelin levels, arterial oxygen tension and wet/dry weight ratios were determined in different periods in control and I-R groups, and the pulmonary ultrastructure abnormities were analyzed under electromicroscope. RESULTS: The plasma levels of NO and ET-1 in I-R animals increased significantly ,compared with those in sham treated control groups. The level of ET-1 had significantly negative correlation with PaO 2 and positive correlation with the value of the wet/dry weight ratios. The swelling and karyopyknosis of capillary endothelium in the lung with I-R groups were observed in ischemia periods. The injuries of endotheliums and typeⅠandⅡ alveolar cells in 0 5 h of reperfusion were more severe than those in ischemia time, and the injuries began to repair in 2 h of reperfusion time. CONCLUSION: In the I-R group, pulmonary capillary endothelium have been injuried, which may play a prominent role in I-R injury and dysfunction of the lung.

The core-crosslinked polymeric micelles were used as a new drug delivery system, which can decrease the premature drug release in blood circulation, improve the stability of the micelles, and effectively transport the drug into the therapy sites. Then the drug bioavailability increased further, while the side effect reduced. Most drugs were physically entrapped or chemically covalent with the polymer in the internals of micelles. Based on the various constitutions and properties of polymeric micelles as well as the special characteristics of body microenvironment, the environment-responsive or active targeting core-crosslinked micelles were designed and prepared. As a result, the drug controlled release behavior was obtained. In the present paper, the research progress of all kinds of core-crosslinked micelles which were published in recent years is introduced. Moreover, the characteristic and application prospect of these micelles in drug delivery system are analyzed and summarized.
