Objective To quantify iron deposition in Alzheimer’s disease (AD),amnestic mild cognitive impairment (aMCI), and normal old people using susceptibility weighted imaging (SWI).Methods Sixty participants (22 aMCI,20 AD,18 normal con-trols)underwent conventional magnetic resonance imaging sequences and SWI using axial/oblique coronal sequences.Phase images were used to calculate bilateral iron deposition in 1 8 regions of interest (ROI)of every participant.The radian angle values were cal-culated and compared between the three groups.Results The radian angle value difference was significant between the aMCI and control groups in the left (L)-hippocampus,L-head of the caudate nucleus,R/L-lenticular nucleus ROIs.The radian angle value difference was significant between the AD and aMCI groups in the R/L-cerebellar hemisphere,R/L-hippocampus,R-red nucleus, R/L-thalamus and splenium of corpus callosum ROIs.Pearson correlation coefficients of the mini-mental state examination (MMSE)scores and many ROIs were significant.Conclusion Iron depositions in the hippocampus,head of the caudate nucleus,len-ticular nucleus and thalamus are significantly different between individuals with aMCI,AD and controls.Using SWI to quantify the iron deposition is a useful tool in detecting aMCI and AD.

Objective The objective of this study was to observe the short-term and long-term curative effects of minimally invasive surgical treatment combined with chemotherapy of localized nasopharyngeal carcinoma in patients,and to clarify the necessity of combination therapy in patients with nasopharyngeal carcinoma.Methods Sixty-two patients with nasopharyngeal carcinoma were enrolled in our hospital from March 2011 to September 2011.The patients were divided into the observation and control groups by random number table method.The patients in observation group were given the application of minimally invasive surgery with postoperative combined chemotherapy with cisplatin and 5-fluorouracil after nasal endoscopic resection.The patients in the control group were given single application of minimally invasive surgical treatment of nasal endoscopic resection.The patients in two groups were observed the efficiency,survival rate and postoperative quality of life after surgery for 1 year or 5 years.Results The effective rate was 83.87％ and 100％ for the survival rate in the observation group after surgery for 1 year;the effective rate was 58.06％ and 87.10％ for the survival rate in the control group.There was significant different between the observation and control groups (P ＜ 0.05).The survival and survival rates were significantly higher than those in the control group after surgery for 5 years (P ＜ 0.05).After surgery 1 year,the scores of the patients in the observation group were significantly higher than those in the control group (P ＜ 0.05).Conclusion The combination of cisplatin and 5-fluorouracil in the treatment of minimally invasive endoscopic nasopharyngeal resection combined with postoperative chemotherapy can significantly improve the short-and long-term survival rates,long-term effective rate,and quality of life in tumor patients after surgery.This is suitable for clinical application.

Background Conventional chemical method to fix the entire eyeball results in the edema of retinal nerve fiber layer and therefore influent the evaluation of tissue structure.Research showed that microwave irradiation can avoid this phenomenon. Objective This study was to investigate the appropriate energy and time duration of microwave irradiation for fixation of rabbit eyes specimen and compare the influence of different fixation methods on retinal structure. Methods Twenty-two New Zealand white rabbits were sacrificed by using venous air embolism.The eyeballs were enucleated from the rabbits and immersed in chemical reagents with glacial acetic acid,methyl aldehyde and chloroform for 2 days as the control group.The eyeballs were immersed in 400 ml physiological balance solution immediately,and then were fixed by microwave irradiation for 80,160,240 and 320 seconds under the lower power as the microwave irradiation groups.In the microwave irradiation+chemical fixation group,the specimens were immersed in chemical reagents for 1-2 hours after the microwave radiation.The morphology of retinal structure was examined and area of retinal detachment was calculated by hemotoxylin and eosin staining under the light microscope. Results A better fixation effect was obtained in the retinal section of microwave radiation for 240 seconds in comparison with that of the traditional chemical reagent fixation method for 2 days.The retina detachment ratio was 16.3%±11.5% for simple microwave method,50.0%±24.5% for chemical method,and 6.7%±7.8% for microwave+chemical method.showing a significant difference among 3 groups(F=32.43,P=0.000).Retinal staining was clear and retinal structure was almost normal in the specimens of microwave+chemical fixation group with 200-240 seeonds microwave irradiation and 1-2 hours chemical fixation. Conclusion Microwave irradiation method is a more ideal way for the fixation of retina because of taking short duration,lower toxicity and better staining.The combination of microwave radiation and chemical reagents can acquire an excellent quality of retinal section.

Nicotinamide phosphoribosyltransferase (NAMPT) is the rate-limiting enzyme in the salvage pathway for the biosynthesis of nicotinamide adenine dinucleotide (NAD+) from nicotinamide. NAMPT is also a cytokine that inhibits the apoptosis of neutrophils under various inlfammatory stimuli, regulates various diseases and closely associates with the progression and prognosis of cancers. However, it is still not clear whether the cytokine-like function of NAMPT is interrelated with the biosynthesis enzyme activity of NAD+. This article aims to provide novel insights for inflammation and cancers treatment by reviewing the function of NAMPT in inflammation, carcinogenesis, cancer progression and its inhibitors, APO866/FK866.

Objective To investigate the effect of triiodothyronine (T3) on neurogenesis in after bilateral common carotid artery occlusion in adult rats. Methods Fifteen adult male Sprague-Dawley (SD) rats were randomly divided into sham operation, 2-vessel occlusion (2VO) and T3 intervention groups (n = 5 in each group ). A chronic cerebral ischemia model was established by the bilateral common carotid artery permanent ligation. Seven days after modeling 5-bromo-2'-deoxyuridine (BrdU) was injectied intraperitoneally and the new proliferating cells were labeled. The BrdU positive cells in SVZ were observed using immunofluorescence staining.Results The numbers of BrdU positive cells in the sham operation, 2VO, and T3 intervention groups were 174. 8 ± 18. 5, 325.0 ± 51.0, and 499. 4 ± 30. 8, respectively. There were significant differences among all the groups (F = 101.68, P ＜ 0. 001 ). The numbers of BrdU positive cells in the T3 intervention group were significantly higher than those in the 2VO and sham operation groups (all P ＜0. 001 ). The numbers of BrdU positive cells in the 2VO group were also significantly higher than those in the sham operation group (p ＜0. 001). Conclusions Thyroid hormones may promote neural progenitor cell proliferation in SVZ in adult 2VO rats.

Objective To study the relationship between serum salusin-α and lipoprotein associated phospholipase A2(Lp-PLA2) in carotid unstable plaque with cerebral infarction. Methods One hundred patients with carotid unstable plaque confirmed by carotid ultrasound, divided into two groups as follows:cerebral infarction group (CI group, n = 50) or without cerebral infarction (plaque group, n = 50). We took 50 health subjects in the same period as control. The levels of serum salusin-α, Lp-PLA2 were detected by ELISA. Results Serum salusin-αlevel was significantly lower in the CI group than in the control group (P<0.01), and was also significantly lower in the CI group than in the plaque group (P < 0.01); Serum Lp-PLA2 level was obviously higher in CI group than in control group (P<0.05), and was also significantly higher in CI group than in plaque group (P < 0.05); The correlation between serum salusin-α level(OR = 0.140, 95% CI: 0.054-0.368, P<0.01) and cerebral infarction was significant in patients with unstable plaque. Conclusions The decrease of serum salusin-α level is significantly in patients with unstable plaque; the increase of Lp-PLA2 is significantly in patients with unstable plaque. The serum salusin-αlevel is a possible risk factor for cerebral infarction.
