Objective To investigate the effect of hemodilution with different plasma substitutes on the expression of tumor necrosis factor-? (TNF-?) and interleukin-1 (IL-1 ) in brain tissue after global cerebral ischemia-reperfusion (I/R) in rats.Methods 116 male Wistar rats weighing 230-280 g were randomly divided into 4 groups: group S ( n = 20) sham operation; group Ⅰ ( n = 32) I/R; group H (n = 32) I/R + hemodilution with 6% hydroxyethyl starch (HAES, 200/0.5) and group G ( n = 32) I/R + hemodilution with gelatine solution. Group Ⅰ, H and G were further divided into 4 equal subgroups with 8 animals in each subgroup according to the duration of reperfusion: 1, 3, 6, 12 h. Global cerebral ischemia was produced by permanent occlusion of bilateral vertebral arteries and cross-clamping of bilateral common carotid arteries for 10 min. The clamping was then released for reperfusion. Global cerebral ischemia was confirmed by coma, loss of righting reflex, bilateral pupil dilation and loss of pain sensation. In group H and G acute hemodilution was performed at 10 min after the beginning of reperfusion. 1 ml? 100 g-1 of blood was removed from the right femoral artery and equal volume of plasma substitute was infused into left femoral vein simultaneously within 5 min. Hematocrit was checked before and after hemodilution. The animals were decapitated after being reperfused for different periods of time as planned and the brains were immediately removed. MTT bioassay and radioimmunoassay techniques were used to determine the IL-1 activity and TNF-? content of the brain tissue respectively. Results The IL-1 and TNF-? levels of brain tissue at 1, 3, 6, 12 h after reperfusion was started were significantly higher in group Ⅰ, H and G than in group S (P

Objective:This work aimed to compare the three-year results, prognostic analysis, and adverse reactions of intensi-ty-modulated radiation therapy (IMRT) positioned by PET-CT and conventional radiotherapy in locally advanced non-small cell lung cancer (NSCLC) patients who underwent concurrent chemotherapy. Methods:A clinical trial was carried out in Qingdao Cancer Hospi-tal. The patients who joined our study were divided into IMRT and conventional radiotherapy (CRT) groups. A total of 48 patients were in the IMRT group and another 40 were in the CRT group. The total dose was 60 Gy throughout the 6-week treatment. The plati-num-based concurrent chemotherapy, combined with regimens such as docetaxel, navelbine, and pemetrexed, was conducted for two cy-cles followed by two to four cycles of consolidation chemotherapy. Results:Significant differences were observed between the curative ratio of the IMRT (77.1%) and CRT (52.5%) groups (P=0.015). No significant difference existed between the short-term survival rates of the two groups. The 1-, 2-and 3-year survival rates were 77.1%, 54.2%, and 22.9%in the IMRT group, as well as 65.0%, 47.5%, and 17.5%in the CRT group, respectively. Significant differences existed in some adverse reactions between the two groups, such as radia-tion gastrointestinal reactions, esophagitis, and pneumonia. More patients died of local recurrence and radiation pneumonia in the CRT group than in the IMRT group. The local recurrence rate was also lower in the IMRT group than in the CRT group. Conclusion:IMRT has obvious advantages in improving the short-term curative effect and reducing adverse reactions. Regarding the survival rate, a long-term follow-up of the two groups is required in the future.

Background With the widely application of phacoemulsication for cataract,dry eye-associated symptoms,such as foreign body sensation and burning frequently occur after cataract surgery in some patients.Objective This study was to evaluate the repair effects of recombinant human epithelial growth factor (rhEGF) on ocular surface injuriy after phacomulsification. Methods This was a prospective study,and informed consent was obtained from each subject before the experiment.One hundreds and twenty eyes of 89 consecutive patients after phacomulsification for age-related cataract were collected and randomized into rhEGF group,hyaluronic acid group and control group and 40 eyes for each.RhEGF drops and hyaluronic acid drops were topically administered 4 times per day for consecutive 4 weeks after surgery in corresponding group,and no drops mentioned above was used in the control group.The 0.3% ofloxacin eye ointment and tobramycin+dexamethasone drops were used as the element drops in all patients of each group.Corneal fluorescein staining score,tear film break-up time ( BUT),Schrimer Ⅰ test without topical anesthesia were performed 1 day before surgery and 1 day,1 week,2 weeks and 1 month after surgery.Results The demography and the relevant surface examinational outcomes were no significantly different among the rhEGF group,hyaluronic acid group and control group in preoperation (age:F =3.74; gender:x2 =0.615; corneal fluorescein staining:F =0.247 ; BUT:F =0.579 ; Schrimer Ⅰ test:F =0.475 ; all P> 0.05 ).With the prolong of the time,the corneal fluorescein staining scores and Schrimer Ⅰ test values appeared a early ascent and latterly decline,and the BUT value showed a early shorten and latterly restore,with a statistically significant differences among various time points( F时间 =6.754,6.079,6.233,P<0.01 ).Meanwhile,statistically significant differences were found in the corneal fluorescein staining scores,Schrimer Ⅰ test values and BUT among these 3 groups (F分组 =4.953,4.511,4.071,P<0.05 ).The corneal fluorescein staining scores in the rhEGF group were significantly lower than those in the hyaluronic acid group at 2 weeks and 1 month after operation(P=0.039,0.014),and the BUT values in the rhEGF group were significantly longer than ones in the hyaluronic acid group at 1 week and 2 weeks after operation (P =0.019,0.007).The Schrimer I test values were significantly reduced in the rhEGF group compared with hyaluronic acid group at 1 week,2 weeks and 1 month after operation (P=0.022,0.003,0.019). Conclusions RhEGF promotes the repair of the ocular surface injury in the patients with age-related cataract after phacomulsification.
