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.

The vip3A gene of Bt9816C was cloned and the sequencing result was submitted to GenBank (accession no.AY945939). The gene was identified as a novel vip3Aa gene, which was assigned name vip3Aa18 by the Bacillus thuringiensis delta-endotoxin nomenclature committee. Subsequently, vip3Aa18 was expressed in Escherichia coli BL21 and bioassay demonstrated that the purified recombinant Vip3Aa18 had high toxicity against Helicoverpa armigera and Spodoptera exigua. The results of sequence analysis revealed that a carbohydrate binding domain exists on the C-termini 536 to 667 residues of Vip3Aa18,which maybe participate in binding to midgut receptors in susceptible insects. Moreover, a transmembrane helices located on N-termini 272 to 292 residues was proposed responding for pore formation. Furthermore, a putative disulfide bond was found in the Vip3Aa18 sequence. The specific structures and sites of Vip3Aa18 sequence imply potential function.

Objective To explore the efficacy and safety of mild hypothermia (MH) in treating the infants with moderate-to-severe neonatal hypoxic-ischemic encephalopathy(HIE),and to make a follow-up of the nerve motor development of the infants at 18 months old after discharge.Methods Totally 61 neonates with moderate-to-severe HIE in Neonatal Intensive Care Unit (NICU) from Jan.2007 to Dec.2013 were retrospectively analyzed.According to before and after MH therapeutic apparatus was used by NICU of Shanghai Children's Hospital,61 neonates of HIE were divided into 2 groups,the conventional treatment group(25 cases) and MH treatment group(36 cases).The patients in both groups were measured respectively by using the amplitude integrated electroencephalography (aEEG) before MH treatment and at 72 hours after M H treatment,by neonatal behavioral neurological assessment(NBNA) on the 28th day after birth,and by adopting Bayley Scales of Infant Development at 18 months old.The adverse reactions,serious disability cases and deaths of MH treatment were recorded.Results Compared with the conventional treatment group,aEEG recording before treatment showed no statistically significant differences in MH treatment group [maximum voltage:(22.4 ±3.1) μV vs(18.6 ±2.5) μV,maximum voltage:(8.2 ±2.6)μV vs(6.5 ±1.9) μV,t =1.264,0.852,all P ＞ 0.05].However,aEEG recording at 72 h after treatment showed statistically significant differences in MH treatment group [maximum voltage:(24.1 ± 3.2) μV vs (30.6 ± 2.8) μV,maximum voltage:(9.7 ± 3.4) μV vs (13.3 ± 2.2) μV,t =6.376,4.257,all P ＜ 0.05].Severe disability cases [24.0％ (6/25 cases) vs 5.6％ (2/36 cases),x2 =4.405,P ＜ 0.05] and deaths [16.0％ (4/25 cases) vs 0 (0/36 case),x2 =6.1 64,P ＜ 0.05] in MH treatment group were significantly decreased,and there was significantly difference in NBNA on the 28th day after birth[(35.9 ± 2.1) vs(39.1-± 1.6),t =3.361,P ＜ 0.05],and scales of neurobehavioral evaluation through follow-up of 18 months old [mental development index (MDI):(85.2 ± 10.7) vs (96.5-± 13.1),t =7.839,P ＜ 0.05].Very few neonates had apnea,coagulation dysfunction,arrhythmia and other adverse reactions in MH treatment course.Conclusions MH treating moderate-to-severe HIE is safe and effective.MH is effective in reducing death and major disabilities in neonates with moderate-to-severe HIE and without significant side effects.MH can obviously improve the development of nervous system disorders in 0-18 months infants,and can significantly improve these infants' Bayley developmental scale neurobehavioral scores.

To investigate the cellular immunity abnormalities of patients with rheumatoid arthritis(RA), peripheral blood lymphocytes subpopulations, interleukin 2 (IL-2) production and natural killer (NK) cell activity were determined in 9 patients with RA. The results showed that there were a remarkable decrease in NK cell activity and poor response to IL-2 stimlulation. IL-2 production and.the expression of membrane-bound IL-2 receptor were increased in RA patients. The percentage of T4 positive cells and the ratio of T4/T8 were also increased in patients with RA. The results indicate that there are severe cellular immunity abnormalities in patients with RA.

Objective To investigate the off-label use status in obstetrics ward so as to provide references for carrying out obstetrics pharmaceutical care and promoting safe medication use in pregnant and parturient women. Methods The prescriptions for pregnant and parturient women from January to June, 2015 in obstetrics ward were investigated. According to drug instructions, the off-label drug use of prescriptions of all selected patients was analyzed in the following aspects:the category of off-label drug use, and drugs use information. In addition, a logistic regression was conducted that modeled the odds of receiving an off-label prescription as a function of the following possible risk factors:pregnant, parturient women and the rank of doctors. The clinical results including the unreasonable drug application, abortion rate and birth defect were compared between the off-label drug use and on-label drug use groups. Results Total of 384 patients were selected, and 5330 prescriptions involving 50 drugs were analyzed. The rate of off-label drug use was 68. 5%, 27. 7% and 24. 0% in patients, prescriptions and drug categories, respectively. The main categories of off-label drug use were super solvent use ( 76. 6%) and indication (14. 3%). The top 3 drugs of off-label use were those for urinary and reproductive (56. 2%), alimentary tract (46. 9%) and traditional Chinese medicine (43. 4%). In addition, there was no significant correlation between the risk of off-label drug use and maternal status and the level of doctors. And no significant difference between the two groups in the unreasonable drug application, abortion rate and birth defect was detected. Conclusion The off-label drug use in obstetrics ward is common in this hospital and most of them are supported by clinical evidence. Due to the lack of more authoritative evidence-based medication, the doctors are suggested to use the drug according to provisions of the drug instructions. When off-label drug use is really needed, it should be based on the surpport of evidence basde medicine,so as to ensure the drug safety for pregnant and parturient women and avoid professional risks.

Objective:To compare immune effects of hepatitis B-BCG combined vaccine and hepatitis B vaccine.Methods:The vaccines were administered to the guinea pig at 0, 1, 2 months. The tests were divided into three parts. The immune effects were compared in three kinds of the combined vaccine and hepatitis B vaccine(Part One), in three lots of the combined vaccine and hepatitis B vaccine(Part Two), in the group of combined vaccine and the group of hepatitis B vaccine and BCG(Part Three). After 1 month of each vaccine dose, serum specimens were measured for anti-HBs by ELISA.Results:The several studies have documented the serum anti-HBs concentritious in the group of combined vaccine in first dose were lower than those of the group of control, and the data showed no significantly difference. However, anti-HBs levels of the combined vaccine group in second vaccine dose and third vaccine dose were higher than those of the control group, and this difference was no longer statistically significant in group of combined vaccine and control, and among groups of combined vaccine.Conclusion:The immune efficacy of HBsAg in group of combined vaccine is similar to the group of hepatitis B vaccine in three doses immunization schedules.
