Alzheimer's disease (AD) is the most common cause of cognitive impairment in older people. With the aging of society is more and more serious, AD caused great burden to patients and society. A β is a classical biomarker of AD, which has been widely used in clinical diagnosis of AD patients. Compared with positron emission tomography (PET) and single photon emission computed tomography (SPECT), near infrared fluorescence imaging has many advantages including highly sensitive, non-invasive, safety and inexpensive. Therefore, many research groups have focused on developing the molecular probes of near-infrared fluorescence (NIRF) imaging. In this article, we will review the progress of the probes of NIRF.

BACKGROUND: Traditional anterior release followed by posterior correction and fusion is frequently used to treat severe and rigid adolescent idiopathic scoliosis, which is considered as Cobb angle of the major curve > 65° and flexibility < 34.5%; however, there are a great majority of complications. Whether isolated posterior correction using pedicle screw fixation combining with bone grafting and fusion may provide better effects on severe and rigid adolescent idiopathic scoliosis needs to be further studied.OBJECTIVE: To evaluate isolated posterior correction using pedicle screw fixation combining with bone grafting and fusion for the treatment of severe and rigid adolescent idiopathic scoliosis. DESIGN: Case analysis.SETTING: Department of Orthopaedics, Renji Hospital, Medical College of Shanghai Jiao Tong University.PARTICIPANTS: Twenty patients with severe and rigid adolescent idiopathic scoliosis, including 8 males and 12 females, were selected from Department of Orthopaedics, Renji Hospital, Medical College of Shanghai Jiaotong University from June 1999 to August 2005. They were 12-18 years old, and the mean age was 14.6 years. All patients were finally diagnosed as X-ray of whole spine. According to King-Moe criteria, patients were classified into type Ⅰ(n =4), type Ⅱ(n =6), type Ⅲ (n =5), type Ⅳ(n =3) and type Ⅴ(n =2). Before surgery, mean Cobb angle of the major curve was 82° (75°-92°), mean flexibility was 30% (20%-40%), and mean shoulder height difference was 15 mm (5-35 mm). Moreover, according to Risser syndrome, patients were classified into degree 1 (n =3), degree 2 (n =5), degree 3 (n =6), degree 4 (n =5) and degree 5 (n =1). All patients and their relatives provided the informed consents, and the experiment was approved by the local ethical committee. Artificial bone was Osteoset provided by Wright Company, USA.METHODS: Patients underwent isolated posterior correction using pedicle screw fixation combining with bone grafting and fusion, and spinous process, lamina of vertebra, zygapophysial joints and transverse process were exposed in a preconcerted fusion area. Pedicle screw was inserted into strategy vertebra using free hand technique according to the anatomic landmark of entry point. Six patients underwent fixation with TSRH system, and the other patients with CDH M8 system. Operative time and blood loss were evaluated after surgery. At 7 days after operation, Cobb angle was measured with X-ray, and correction rate of major curve was calculated. While shoulder height difference and admission duration were evaluated simultaneously. Complications and recovery states were followed up in the next 4 years.MAIN OUTCOME MEASURES: ① Operative time and blood loss; ② Cobb angle and correction rate of major curve; ③ shoulder height difference and admission duration; ④ follow-up results.RESULTS: All 20 patients were included in the final analysis. ① Operative time and blood loss: Operative time lasted from 3.2 to 4.3 hours, and the mean time was 3.5 hours. Blood loss ranged from 660 to 1 070 mL, and the mean loss was 865 mL. ② Cobb angle and correction rate of major curve: Cobb angle of the major curve ranged from 82° (75°-92°) before surgery to 31° (22°-37°) after surgery, and the mean correction rate was 62%. ③ Shoulder height difference and admission duration: Mean should height difference before surgery was 15 mm (5-35 mm). Postoperative lateral film of spine indicated that thoracic and lumbar vertebra generally suffered from normal posterior and anterior convexity, and mean shoulder height difference after surgery was 7.5 mm (0-11 mm). The admission duration lasted from 8 to 11 days, and the mean duration was 9 days. ④ Follow-up results: All patients were followed up in the next 4 years after surgery. The cobb angle correction of major curve remained unchanged, and the instrumented segments were completely fused without instrumentation failure.CONCLUSION: Isolated posterior correction using pedicle screw fixation combining with bone grafting and fusion may effectively cure severe and rigid adolescent idiopathic scoliosis, which is considered as Cobb angle of the major curve between 75° and 92° and flexibility ≥ 20%.

Objective To observe changes of motilin(MTL) levels in gastric body, duodenum and plasma in rat model of acute incisional pain.Methods A total of 156 healthy male adult SD rats,weighing 180-220 g,were randomized into two groups:control group (group C,n=78) and incisional pain group (group P,n=78),Rats in P group received incision on the right plantaris. Values of paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) at dif?ferent time points of 24 hours before operation (T0) and 1 hour (T1),6 hours (T2),24 hours(T3),48 hours (T4) and 72 hours (T5) after operation were measured in six rats chosen randomly from each group. Twelve rats were chosen from each group at T 0-5, and sacrificed. The MTL levels in plasma, the mucosal tissues of gastric body and duodenum were detected by ELISA. Re?sults Compared with group C, PWMT and PWTL were significantly decreased at T1-4 in group P. The MTL levels were sig?nificantly decreased in plasma and gastric body (P<0.05).The MTL level was significantly increased at T1-4 in duodenum (P<0.05),and no significant changes were found at T0 and T5 in P group(P>0.05). The plasma MTL levels were positively correlated with PWMT and PWTL (r=0.952,r=0.879,respectively,P<0.01) in P group. The MTL levels in gastric body were positively correlated with PWMT and PWTL(r=0.970,r=0.931,respectively,P<0.01) in P group. The MTL levels were neg?atively correlated with PWMT and PWTL(r=-0.991,r=-0.975,respectively,P<0.01) in duodenum in P group. Conclu?sion The MTL levels in plasma and gastric body are decreased in rat model of acute incisional pain, and increased in duo?denum.

Objective:To explore the association of its polymorphism of TFRC with the susceptibility, clinical and pathologic phenotypes of IgA nephropathy. Methods: A total of 380 patients with IgA nephropathy and 250 normal controls were enrolled in the study. The regions with 424G/A and -5184C/T polymorphism sites of TFRC were amplified by PCR from genomic DNA and then the PCR-RFLP were performed by restriction enzymes, BanⅠ and BsmA Ⅰ, respectively. The genetic association of genotypes with the clinical and pathologic phenotypes was analyzed. Results: The distribution of frequency in TFRC was consistent with Hardy-Weinberg equilibrium; however, we found no significant difference in genotypes distribution between patients and controls. There were no differences between genotypes in age, blood pressure, 24 h urine protein excretion, serum creatinine, creatinine clearance and serum IgA. 424G/A and -5184C/T polymorphisms were associated with immunofluorescent intensity of IgA deposit in mesangial area, though there was no difference in pathological lesions evaluated by HAAS grade. Conclusion: The polymorphisms of TFRC in 424G/A and -5184C/T sites were not associated with susceptibility to IgA nephropathy, but associated with density of immunofluorescence of IgA in mesangium in our large population based Chinese patients. The association of IgA nephropathy and other polymorphism sites, as well as interaction between TFRC polymorphism and other genes' polymorphisms, neededs to be further investigated.
