Objective To explore the effects of maternal exposure to dibutyl phthalate ( DBP) ,an environmental estrogen on the proliferation and differentiation of neural stem cells ( NSCs) in the neural tube of neonatal rats. Methods A total of 40 male and 40 female SD rates at age of 4 to 5 months,were matched,and the morning when vaginal plugs were found was designated as E0. Then the 40 pregnant rats were randomly divided into 4 groups,3 DBP exposure groups ( 25,75,and 225 mg/kg) and control group. DBP at corresponding doses were dissolved in corn oil,and administrated by intragastrically injection once per day from E0 till delivery,while those of control group were given corn oil. Brain tissue of newborn rats was collected for primary culture of NSCs. Then the cell colony formation was counted to detect the NSCs proliferation. Then 10% fetal bovine serum ( FBS) was added into the culture medium to induce the NSCS to differentiate. Neu-N and GFAP immunofluorescence stainings were used to detect neurons and astrocytes,and their morphological changes were observed. Results The proliferation of NSCs was decreased significantly after DBP administration. Compared with the control group ( 40. 53 ? 4. 65) % ,the colony formation rate of middle-and high-dose DBP exposure groups was significantly reduced and in a dose-dependent manner ( 30. 96 ? 3. 80) % ,( 15. 35 ?5. 29) %,( 6. 58 ?1. 43) %,P

Objective To investigate the cognitive status of nursing of cancer patients among nurses of cardiothoracic surgery department,to discuss countermeasures to improve nursing quality of tumor patients of cardiothoracic surgery department. Methods 150 nurses of cardiothoracic surgery department from November 2009 to November 2010 in five hospitals of a certain city were selected as the research object.The elf-made questionnaire about cognition of cancer patients nursing was adopted for investigation.The cognition condition of health education,psychological care,death education,care of cancer pain of 150 nurses was taken for statistics. Results The study showed that 150 cardiothoracic surgical nurses mastered the health education knowledge best,the average score was(88.6 ± 11.3).The knowledge of death related knowledge was the worst,the average score was (64.5 ± 21.6).The differences of mastering degree of psychological care and pain related knowledge level for 5 hospital nurses were quite significant.The differences of psychological care knowledge levels of hospital A and C,D were significant.The differences of care of cancer pain of hospital B and A,E,F were significant. Conclusions Based on the cognitive status of cardiothoracic surgery nurses for nursing of cancer patients,appropriate theoretical and practical training can be adopted in order to improve cognitive level of related knowledge about nursing of cancer patients among cardiothoracic surgery nurses,so that the nursing quality for cancer patients can be improved.

Objective:To study the clinical significance of β2-microglobin(β2-MG)and fibronection (Fn) contents in patients with nasopharyngeal carcinoma.Methods:The contents of serum β2-MG and Fn were detected by radioimmunoassay and agar-diffusion methods in 60 patients with nasopharyngeal carcinoma before and after radiotherapy,also in 60 normal subjects as control group.Results:The contents of serum β2-MG and Fn were 2.99±1.11mg/L(β2-MG)and 134.60±28.93mg/L(Fn) in 60 patients with nasopharyngeal carcinoma,2.16±0.50mg/L(β2-MG)and 196.16±34.65mg/L(Fn)in 60 health subjects,respectively.Those results showed that the content of β2-MG in patients group was higher than that in control group (P＜0.05),and the content of Fn in patients group was lower than that in control group(P＜0.05).After radiotherapy of patients group,the content of β2-MG were lower(2.16±0.55mg/L)than that before radiotherapy(P＜0.05).Conversely,the content of Fn was higher(180.53±34.66mg/L)than after radiotherapy(P＜0.05).Conclusions:The detection of serum β2-MG and Fn have clinical significance on the evaluation prognosis of patients with nasopharyngeal carcinoma.

Objective To explore the impact of medication self-management module on treatment compli-ance and social function of patients with schizophrenia. Methods 66 inpatients with schizophrenia in their non-acute stage were randomly divided into training group(n=33) and control group(n=33). Both groups received the anti-psychotics therapy. Medication self-management module was only given to the training group for 8 weeks.All subjects were follow up for 6 months and were evaluated with self-made drug treatment compliance rating scale,self-made work ability rating scale, social disability screening schedule(SDSS). Results Treatment compliance,the total scores of SDSS of training group were significantly higher than that of control group after 8 weeks and 6 months: treatment compliance (χ~2=9.188,29.630, P < 0.01); the total scores of SDSS ((2.63±2.74) vs (5.27 ±3.05), (1.69±2.35) vs (4.91±3.06), P=0.000); work ability of training group was significantly higher than that of control group after 6 months (χ~2=19.443, P=0.000). Treatment compliance (χ~2=8.053, P=0. 018), the total scores of SDSS((2.63±2.74) vs (6.81±3.06), P=0.000) of training group after 8 week and 6 months were significantly higher than that of pretraining. Treatment compliance and work ability of both groups on 6 months follow up were significantly lower than that of 8 weeks (P < 0.01). Correlation analysis can-firmed that there was positive relation between the total scores of SDSS and treatment compliance, work ability on 6 months later. Conclusion Medication self-management module could significantly improve treatment compliance,social function and work ability of patients with schizophrenia.

Objective To study the effect of nerve growth factor(NGF)in survival of super-length random flap.Methods The experiment employed the animal model of random flap in Wistar's rat back,applied 66.7 μg NGF locally in trial group's flap at the first day after operation with auto-control.The survival proportion,skin temperature and survival rate of random flap were observed,and the blood flow,the blood flow velocity,the blood flow volume change of random flap were measured by the laser and photic-conduct fiber means in differ time.Results The survival proportion(7.12±1.54)cm2 and survival rate(92±5)%of random flap of trial group was obviously higher(P＜0.05)than those in control group[(5.23±0.19)cm2,(69±5)%]after pedicle division.The blood flow,the blood flow velocity,the blood flow volume and skin temperature in the midge and at the end of random flap in the trial group were obviously higher than those in control group 1 day after operation(P＜0.05),and the blood flow velocity in the pedicle of random flap in the trial group was increased markedly(P＜0.05).The blood flow volume and skin temperature in the pedicle of random flap in the trial group were higher than those in control group 3 days after operation(P＜0.05).The survival of randomflapinthetrial groupwere very significantly increased than those in control group 7 days after operation(P＜0.01).Conclusion NGF can increase flap's blood flow,blood flow velocity and blood flow volume,enhancing survival of the big-proportioned and super-length random flap.

Objective To introduce a new way to solve the problem of field-field junction in the traditional radiotherapy of the nasopharyngeal carcinoma better.Methods Using the 3-dimentional planning system,the dose distribution of traditional radiotherapy and the electronic beam irradiation technology of L shape field for nasopharyngeal carcinoma in 2D-or 3D-CRT could be gotten.Results The dose coverage of V95 of the gross tumor volume(GTV)satisfied the clinical requirements.The highest dose in the electronic beam irradiation of L shape field was 7200 cGy,while it was 8900 cGy in the traditional way.The volume of dose that over 6500 cGy of throat was 19.64 ％ in the former,the latter was 31.95 ％.Conclusion The electronic beam irradiation technology of L shape field is better than the traditional radiotherapy in field-field junction and in dose distribution.Since that,the electronic beam irradiation technology of L shape field is worth of application for the treatment of nasopharyngeal carcinoma.
