Objective To investigate the brain protective effects of isoflurane preconditioning for local cerebral is-chemia adult rat model by detecting HIF-1α, HO-1 and Bcl-2 expression level. Methods 84 two-month old Spra-gue-Dawley male rats were randomly divided into sham group, ischemia-reperfusion group ( MCAO group) and isoflurance preconditioning group (ISO group). ISO group was exposed to isoflurane for 30 min and then underwent a 90 min middle cerebral arterial occlusion (MCAO), while MCAO group underwent MCAO only. At 24 h after reperfusion all the groups were investigated by modified neurological severity score for neurological deficits, TTC staining for infarct percentage. Cerebral cortices were harvested for HIF-1α, HO-1 and Bcl-2 protein expression level detection at 6 h, 24 h and 72 h after reperfusion using RT-PCR and western blot. Results The mNSS score and infarct percentage in ISO group decreased significantly compared with those of MCAO group at 24 h after reper-fusion(P < 0. 05). Compared with the MCAO group, ISO group had significantly up-regulated protein levels of HIF-1α, HO-1 and Bcl-2 at 6 h and 24 h after reperfusion(P < 0. 05). There was no difference between ISO group and MCAO group for 3 gene expression at 72 h(P > 0. 05). Conclusion Isoflurane preconditioning plays short-term cerebral protective effect through the up regulation of HIF-1α, HO-1 and Bcl-2 gene expression.

Objective To investigate the value of ultrasound-diffuse optical tomography(US-DOT) in evaluation of the response to neoadjuvant chemotherapy (NCT) in patients with breast cancer.Methods Fifty women with breast cancer confirmed by biopsy-pathology scheduled to undergo NCT were enrolled.US-DOT was performed and the total hemoglobin concentration(HbT) prior to and at the end of NCT.According to the response to treatment in solid tumors,patients were divided into complete response(CR) group,partial response (PR) group,stable disease (SD) group and progressive disease (PD) group.The analysis of variance compared the differences of HbT before and after NCT in each group; Pearson correlation analyzed the relationship between the relative HbT variation and the tumor size changes;Mixedeffects model analyzed the relationship between HbT and tumor size.Results After NCT,CR group had 8 cases,PR group 30 cases,SD group 12 cases and no PD cases.Before and after NCT,the mean relative variations of HbT before and after NCT were-0.525 ± 0.222,-0.328 ± 0.180 and-0.173 ± 0.167 in CR,PR and SD groups,respectively.The differences of HbT before and after NCT were statistically significant in each group (P ＜0.05).There was significant difference among tumor diameter and HbT in CR group and PR group (P ＜0.001);while in the SD group,there was no difference among tumor diameter and HbT (P ＞ 0.05).The change of HbT after NCT showed positive correlation with the change in tumor size (r =0.6).Mixed-effects model also showed that HbT change was associated with tumor size.Conclusions USDOT marker HbT is closely related to tumor size of breast cancer before and after NCT and may be applied to evaluate the response of breast cancer to NCT.

BACKGROUND:The research at home and abroad for appropriate immature myocardial cardioplegia has no breakthrough, and it may be a better mean to improve the protection effect of existing cardioplegia on immature myocardial by adding ingredients. Adenosine can reduce ischemia and neutrophil-mediated reperfusion injury, and salvia miltiorrhiza can reduce the content of ischemic myocardial lipid peroxide and increase the scavenging of myocardial cells to oxygen radical. OBJECTIVE:To investigate the protection effect of improved myocardial protection fluid containing adenosine and salvia miltiorrhiza on the heart, liver and kidney. METHODS:Sixty cases of infant open heart operation of the first time were randomly divided into three groups, 20 cases in each group. The adenosine group received the improved myocardial protection fluid added with adenosine, the combination group received the improved myocardial protection fluid added with adenosine and miltiorrhiza salvia, and the control group received the improved myocardial protection fluid in the same volume. The blood samples were taken at the time before anesthesia induction, 30 minutes after cardio pulmonary bypass beginning, 1 hour after cardio pulmonary bypass end and 24 hours after cardio pulmonary bypass end. The serum levels of the creatine kinase, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine, tumor necrosis factor-α, interleukin-6, interleukin-8 and interleukin 10 were detected. RESULTS AND CONCLUSION:The serum levels of the alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine and creatine kinase in three groups were increased, but the control group was increased significantly (P<0.01), and there were significant differences between adenosine group and combination group (P<0.05);the levels of tumor necrosis factor-α, interleukin-6 and interleukin-8 were significantly increased after operation (P<0.05). The levels of tumor necrosis factor-α, interleukin-6 and interleukin-8 in the control group were significantly higher than those in the adenosine group and combination group before induction and at the same time point (P<0.01);at 3 minutes and 24 hours after cardio pulmonary bypass, the level of interleukin-10 was increased in three groups, but the level of interleukin-10 in the adenosine group was significantly higher than that in the control group (P<0.01). The results indicate that improved myocardial protection fluid has great protection effect on immature myocardial, and can significantly reduce the serum levels of tumor necrosis factor-α, interleukin-6 and interleukin-8, promote the secretion of interleukin-10 that can inhibit inflammatory cytokine and can significantly reduce the inflammatory response caused by cardiopulmonary bypass. So the improved myocardial protection fluid has protection effect on important organs, such as heart, lung, liver and kidney.

Objective To investigate the status quo of quality of life and family environment of children and adolescents with diabetes, also to explore the relationship between family environment and the quality of life, so as to give some support for family nursing. Methods A total of 58 diabetic children and adolescents were asked to complete Pediatric Quality of Life Inventory,meanwhile their parents were asked to complete the family environment scale, relativity of life quality of diabetic children and adolescents with family environment was analyzed. Results The physical function, school function, psychosocial health and total quality of life of diabetic children and adolescents' were lower than healthy children; family conflicts and control were higher than normal, while knowledge was lower than normal. Their quality of life was positively correlated with family knowledge and control, family control and success contributed a lot to life quality. Conclusions The health professionals should improve the communication between children and parents, sharing the diabetes responsibility, reduce the family conflict, in order to manage diabetes effectively and improve the quality of life.

Background and purpose:Lung cancer is thought to be caused by multiple-step carcinogenesis. Identification of the genetic alterations that occur in tumors is an important approach to understanding carcinogenesis. We identified chromosomal abnormality in lung cancer by the molecular cytogenetic techniques of comparative genomic hybridisation(CGH),the technology could help to comprehend the relationship between chromosome abnormality, different patho-types,and clinical features of lung cancer.Methods:CGH was used to detect the global genomic aberration in the fresh cancer tissue cells from 30 patients with lung cancer.Results:Chromosomal abnormality were detected in all of 30 cases with lung cancer,the altofrequent gains in 1p11-p22,5p11-p14,16p 11-P12,19q13, 19p 13,20p12,21q21 and the altofrequent losses in 5q,6p24-pter,9p31-qter,13q21-qter,14q21-qter were found in all three types of lung cancer,the marked differences of chromosomal abnormalities in three types of lung cancer were also found.Conclusions:The cytogenetic aberration exists generally in lung cancer cells,the cytogenetic aberration is the base of the initiation and progression of the lung cancer.There are some different chromosomal abnormalities between different types of lung cancer,which may serve as a marker to differential diagnosos of the three types of lung cancer.As to the progression of malignant neoplastic disease,the complexity of chromosomal abnormality is obviously elevated.Different carcinogenic agents(smoking for example)may induce different chromosomal abnormalities.

Objective To investigate the effects of enteral nutrition with galactooligosaccharides (GOS) on serum inflammatory cytokines in rats with severe acute pancreatitis (SAP). Methods SD rats were randomly divided into sham operation control group, SAP with enteral nutrition (EN) group and SAP with EN supplemented with GOS (GOS-EN) group, and each group was divided into 4 d and 7 d subgroups according to the time that animals were sacrificed (n=8 in each subgroup). Rat SAP models were established by injection of 38 g/L sodium taurocholate beneath the pancreatic capsule. The serum amylase, inflammatory cytokines TNF-α, IL-2 and IL-10 were detected. Results At each time point, the levels of serum amylase in all SAP groups were significantly higher than those in sham operation control group (P < 0.01), and the levels in GOS-EN group were significantly lower than those in EN group (P < 0.01). The levels of serum TNF-α and IL-10 in all SAP groups were significantly higher than those in sham operation control group (P < 0.01), while the levels of IL-2 in all SAP groups were significantly lower than those in sham operation control group. The levels of TNF-α in GOS-EN group were significantly lower than those in EN group (P <0.05), while the levels of IL-2 and IL-10 and the ratio of IL-10/TNF-α were significantly higher than those in GOS-EN group (P < 0.05). Conclusion Early EN supplemented with GOS could modulate the balance of pro- and anti-inflammatory response.

AIM: To compare the safety and efficacy of conjunctival autograft transplant ( CAT ) and limbal - conjunctival autograft transplant (LCAT) for primary pterygium.
METHODS: In this prospective, randomized and controlled clinical study, 120 patients ( 120 eyes ) diagnosed with primary pterygium were collected in NO. 474 Hospital of Chinese PLA from January 2014 to January 2015. The 120 patients enrolled in the study in turn, and divided into two group by the odd and even number. The odd number underwent CAT and the even number underwent LCAT.
RESULTS:One hundred and seven patients (107 eyes) completed the follow-up of 1a, including 54 patients (54 eyes) from the CAT group and 53 patients (53 eyes) from the LCAT group. Four patients (4 eyes, recurrence rate 7. 4%) in the CAT group and 2 patients ( 2 eyes, recurrence rate 3. 8%) in the LCAT group developed recurrence. However, there were no significant in recurrence rate between CAT group and LCAT group (P =0. 678).
CONCLUSION: CAT and LCAT might be both effective treatment for primary pterygium for reducing the recurrence rate of pterygium. However, LCAT is the optimal surgical method for primary pterygium.

Objective To investigate the reliability and validity of Simple Facial Grading System (SFGS) in patients with idiopathic facial palsy. Methods 80 patients with idiopathic facial palsy were evaluated with the House-Brackmann (H-B) scale and SFGS before and every 2 weeks after treatment until 12 weeks or recovery. They were assessed by 2 testers before and 2 weeks after treatment. The results were analyzed and compared. Results The Cronbach's α coefficient was 0.93 of SFGS, and 0.74 of H-B scale. The intraclass correlation coefficient (ICC) between testers was 0.84 or higher of SFGS, and 0.77 or higher of H-B scale. The Spearman's rank correlation coefficient between SFGS and H-B scale was 0.73, Kappa coefficients was 0.81 for grade II, 0.74 for grade III, 0.49 for grade IV, 0.66 for grade V, and 0.92 for grade VI. The scores of SFGS and H-B scale positively correlated with the recovery time. Conclusion SFGS is a kind of evaluation for peripheral facial paralysis with satisified reliability and validity, which can be applied to evaluate the severity and outcome during acute stage.
