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:To evaluate the effects of different enamel conditioners in combination with an adhesive on the shear bond strength and the adhesive remnant index in vitro.Methods:One hundred and eight permanent healthy premolars from orthodontic patients and fresh saliva from a healthy young volunteer were collected.The teeth were cleaned,dried and etched by phosphoric acid,polyacrylic acid or Transbond plus SEP respectively(36 teeth for each agent).Then the teeth were bonded to brachet by RMGICs with the presence of water,saliva on the tooth surface or without any of them respectively(12 teeth in each group).After bonding,all samples were tested on a testing machine of Instron.Shear bond strength and adhesive remnant index were recorded.Results:Highest mean shear bond strength was observed in the group of teeth etched by Traspond plus SEP and bonded by RMGICs with the presence of saliva.Higher mean shear bond strength was obtained with the presence of saliva or water on the tooth surface than without any of them.Conclusion:Transbond plus SEP conditioning followed by RMGICs bonding may produce high shear bond strength between moistured tooth surface and brachet.

The biological incompatibility of traditional peritoneal dialysis fluids(PDF) is the main reason for the poor outcomes of long-term peritoneal dialysis and the high rate of technical failure.Recently,two-compartment PDF has been applied in the treatment of peritoneal dialysis patients,and reportedly has lots of clinical advantages due to its better biocompatibility.This paper presents an overview of recent advances in the studies of two-compartment PDF.

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.

Objective To explore the clinical features of female recurrent major depression(MD) patients with and without suicidal ideation.Methods 301 female recurrent major depression patients were interviewed by specially trained interviewers using computer evaluation system and divided into suicidal ideation group and non-suicidal ideation group according to suicidal ideation.The comparisons between the two groups were investigated on items of demographic, clinical data, assessment of psychopathology, Eysenck neuroticism questionnaire, stressful life events.Results 66.4％ of MD patients have suicidal ideation.Compared with non-suicidal ideation group, there were more total number of MD symptoms (8.58±0.77, OR=2.476, P=1.154× 10-9) and melancholia symptoms (6.74±1.07, OR=1.546, P=0.001) and it was more common in the factors of less appetite (OR=2.201, P=0.011), lose weight (OR=2.030, P=0.004), early morning awakening (OR=1.774, P=0.045), worthless (OR =2.352, P=0.014), impaired decision-making (OR=2.044, P=0.018), hopelessness (OR=7.130, P=6.651 × 10-9) ,helpless (OR=2.046, P=0.049) in suicidal ideation group.Also in suicidal ideation group the scores of neuroticism dimension (OR=1.631, P=0.024) were higher, and they were more suffered from stressful life events (OR=1.302, P=0.008).Binary logistic regression analysis indicated that total number of MD symptoms (OR=4.840, P=1.154×10-8) ,stressful life events (OR=1.392, P=0.014) and hopelessness (OR=3.528, P=0.008)were significantly associated with suicidal ideation.Conclusion Specific clinical features are associated with suicidal ideation among female patients of recurrent depression disorder.Hopelessness, stressful life events are risk factors of suicide ideation in female recurrent major depression patients.Integrated clinical assessment should be taken for recurrent major depression patients with suicidal ideation.

Objective To explore the clinical features of female diagnosed recurrent major depression (MD) comorbidity with general anxiety disorder (GAD).Methods 301 females patients with recurrent major depression were interviewed by specially trained interviewers with using computer evaluation system and divided into comorbidity group and non-comorbidity group according to whether comorbid MD with GAD or without GAD.The comparison between the two groups included items of demographic,clinical data,assessment of psychopathology,Eysenck neuroticism questionnaire (EPQ),stressful life events,parental bonding instrument.Results 25.2％ of patients of MD coexistence GAD.There was no significant difference in sociodemographic data between the two groups.Significant differences among total number of depression symptoms(OR=1.439,95％ CI =1.049-1.975,P =0.024),duration of illness(OR=1.253,95％ CI =1.010-1.475,P=0.048),psychomotor agitation(OR=2.031,95％ CI =1.123-3.676,P=0.019),suicidal thought(OR=2.228,95％ CI =1.010-4.912,P=0.047),anxiety(OR =5.547,95％ CI =1.935-15.896,P=0.001),irritable(OR=1.956,95％ CI =1.081-3.542,P=0.027) were identified between the two group.In the comorbidity group,the score of nenroticism dimention derived from EPQ was also higher(OR=2.287,95％ CI =1.674-3.124,P=2.287× 10-7) than that of non-comorbidity group.There was no significant difference of stressful life events between two groups(OR=1.118,95％ CI =0.913-1.368,P=0.280).Conclusion This study suggests the phenomena that female patients of recurrent depression disorder comorbidity with general anxiety disorders is common in clinical.The patients comorbid MD and GAD have more symptoms,neuroticism and be worse in severity.

Objective To understand the homology of clinical isolates from patients with carbapenem-resistant Klebsiella pneumoniae(CRKP)infection and isolates from environment in a medical institution.Methods One CRKP strain isolated from a patient in this hospital and 4 strains of Klebsiella pneumoniae(K.pneumoniae)isolated from patient's surroundings were collected,susceptibility of 5 strains to commonly used antimicrobial agents was detected,production of carbapenems in 5 strains were detected by modified Hodge testing and carbapenem inactivation method(CIM),homology analysis was performed by pulsed-field gel electrophoresis(PFGE).Results Antimicrobial susceptibility testing results showed that 5 strains of K.pneumoniae(1 from patient,4 from the patient's ward surroundings,including hands of nursing aides,solution bottle opening,handle for lifting and dropping bed,and bedrail)were all resistant to other antimicrobial agents except to cephamycin and aminoglycosides.The modified Hodge testing and CIM confirmed that 5 strains all produced carbapenemases;PFGE results showed that electrophoretogram of CRKP isolated from solution bottle opening of ward,bedrail,and handle for lifting and dropping bed were the same as CRKP isolated from patient,while electrophoretogram of CRKP isolated from hands of nursing aides had 2 different bands,there was a close relationship between the strains.Conclusion The same type of CRKP were isolated from patient and his surroundings,it is necessary to implement healthcare-associated infection(HAI)control system,isolate infected patient,and strengthen environmental cleaning and disinfection,so as to avoid the outbreak of HAI.

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.
