Blue laser imaging (BLI) is a new endoscopic system equipped with the laser beam emitting two different wavelengths.It produces bright and high resolution images for observation of microvascular and microsurface patterns of esophageal and gastric mucosa, helping the diagnosis of early upper gastrointestinal cancer.Compared with the existed endoscopic techniques, BLI shows its unique advantages.In this article, advances in application of BLI in diagnosis of early upper gastrointestinal cancer were reviewed.

Objective To evaluate the clinical outcomes of the hybrid technique of posterior osteotomy with short segmental fusion and dual growing rod technique for severe rigid congenital scoliosis.Methods Seven patients (2males,5 females) undergoing this hybrid technique for severe rigid congenital scoliosis in our hospital from 2006 to 2011 were retrospectively studied.The average age was 5.9 years (range,2-10).The Risser sign of all the patients was 0.The follow-up time was 59.4 months (range,36-83 months).The patients' charts were reviewed.The analysis included age at initial surgery and the latest follow-up,number and frequency of lengthening,and complications.Radiographic evaluation included measured changes in scoliosis Cobb angle,thoracic kyphosis,lumbar lordosis,trunk shift,length of T1-S1 and instrumentation.Results All patients were treated with posterior osteotomy with short segmental fusion and dual growing rod technique.There were 48 total surgeries,41 of which were lengthening procedures,for 7 patients.The average lengthening was 5.9 per patient.The mean scoliosis improved from 81.4° to 40.1 ° after initial surgery and was 41.1 ° at the final follow-up.The average T1-S1 length was of 1.12 cm per year.The Campbell's space available for lung ratio increased from 0.87 to 0.97.Conclusion Osteotomy with short fusion could help to improve the correction of the growing rod and eliminate the large asymmetric growth potential around the apex,with little influence to the length of the spine.Dual growing rod technique could maintain correction achieved at initial surgery while allowing spinal growth to continue.However,this technique is relatively more aggressive and technique demanding.And the patients need numbers of surgeries.

Objective:To develop an HPLC method for the determination of nintedanib in rabbit plasma and study the pharmacoki-netics of nintedanib in rabbits. Methods:The separation was performed on an Agilent ZORBAX SB-C18 column. A mixture of acetoni-trile-0. 1% trifluoroacetic acid-water (35∶ 20∶ 45) was used as the mobile phase at a flow rate of 1. 0 ml·min-1. The detection wavelength was set at 286 nm. Carbamazepine was used as the internal standard and nintedanib was extracted by ethyl acetate from plasma under basic condition. Totally 6 rabbits were given 20 mg·kg-1 nintedanib with intravenous administration. The blood samples were collected from the auricular vein at different time points after the administration. The concentration of nintedanib in plasma was detected by the HPLC method. The pharmacokinetics parameters were analyzed by DAS program. Results: An excellent linear rela-tionship was obtained within the range of 0. 05-10. 00 μg·ml-1(r=0. 999 8). The intra-day RSD was 5. 55%, 4. 53% and 2. 74%and inter-day RSD was 6. 15%, 5. 45% and 3. 15%, respectively for the three concentrations(0. 10, 2. 50 and 7. 50μg·ml-1), and the relative recovery was (98. 50 ± 5. 47)%, (100. 25 ± 4. 54)% and (99. 94 ± 2. 74)%, respectively. The main pharmacokinetics parameters of nintedanib were as follows: Cmaxwas (3.01 ±0.35) μg·ml-1, t1/2 was (4.38 ±1.53) h and AUC0-t was (11.67 ± 1. 71) μg·h·ml-1 . Conclusion:The method is simple, rapid and accurate, and can be used to determine the nintedanib concentra-tion in rabbit plasma and study its pharmacokinetics. Nintedanib is fitted the first-order elimination kinetics in rabbits.

OBJECTIVE: To explore the effects of piracetam on superoxide dismutase(SOD) activity and malonaldehyde(MDA) content in brain tissues of D-galactose-induced ageing rats.METHODS: 30 SD rats were randomized to one of the 3 groups: blank control group(NS),model group(D-galactose+NS) and piracetam group(D-galactose+piracetam 432 mg?kg-1?d-1).All the rats were put to death at 90 days after medication,and the SOD activity and MDA content in brain tissues were determined.RESULTS: As compared with the blank control,the SOD activity decreased(P

A rapid and simple method for the determination of cyanide in blood was developed based on pinhole shell-isolated nanoparticles (pinSHINs)-enhanced Raman spectroscopy and an online lysis-purging and trapping approach.In the online lysis-purging and trapping device, the bound cyanide in blood can be cleaved through sulfuric acid acidification, and transferred into HCN volatile gas, then purged into alkaline solution to form NaCN solution, thus high-efficient liberation and entrapment of cyanide from the methemoglobin-bound form can be achieved.The pinSHINs substrate is quite stable to weaken the gold-dissolution effect caused by cyanide under strong alkaline condition, and therefore the detection window can be prolonged to 1 h comparing with 5 min of AuNPs.A limit of detection down to 10 μg/L and a linear range from 100-2000 μg/L in blood were achieved in this method.This method was further applied to rapid measurement of blood samples of cyanide exposed rats and clinic poisoned patients, which provided a sensitive, selective and reliable way for rapid detection of cyanide poisoning.

Objective To optimize the volatile oil extraction and inclusion process of Wenweiyang capsules. Methods An orthogonal test was adopted in this study. The extraction technology was optimized for the yield of volatile oil regarding the amount of water loaded, grain size of medicinal material, and decoction time as factors. The inclusion technology was optimized for the inclusion yield and volatile oil inclusion rate using the ratio ofβ-CD:oil, amount of water and grinding time as factors. Results The optimized extraction parameters were as follows:breaking medicinal material through 10 mesh screen, adding 6 fold volume of water and extracting for 5 h. The optimized inclusion progress was grinding at theβ-CD:oil ratio of 81, loading equivalent amount of water and grinding for 30 minutes. The average yield of volatile oil is 1. 72%, the average inclusion rate is 93. 01% and the average volatile oil inclusion rate is 74. 82%. Conclusion The extraction and inclusion technology is simple, reliable, which can effectively retain the volatile oil and provide evidence for the preparation of Wenweiyang capsules.

Objective To investigate the perioperative complications and risk factors of one-stage posterior vertebral column resection (VCR) for severe spinal deformity.Methods From September 2004 to July 2012,39 patients with severe and fixed spinal deformity underwent one-stage posterior VCR,including 15 males and 24 females,aged from 3 to 53 years (average,16.9 years).There were 24 cases of kyphoscoliosis (mean coronal Cobb angle:85.1°,mean sagittal Cobb angle:92.9°),7 cases of scoliosis (mean coronal Cobb angle:81.1°),and 8 cases of kyphosis (mean sagittal Cobb angle:94.4°).Eleven patients had neurological compromise.The perioperative complications and related risk factors of 39 patients were retrospectively analyzed.Results All patients were followed up for 3 to 72 months (average,29.4 months).There were 15cases (13 patients) of perioperative complications.Neurological complications occurred in 6 patients (15.4％),among whom one patient presented complete paraplegia after surgery and 5 patients presented transient paresthesia or muscle weakness.Adults had a significantly higher incidence of neurological complications than teenagers.The incidence rate of neurological complications was 36.4％ in patients with preoperative neurological compromise,while 7.1％ in patients without preoperative neurological compromise.All patients with postoperative neurological complications had kyphosis before operation,and the incidence of neurological complications increased significantly in patients with severe kyphosis (Cobb angle ≥90°).Prolonged respiratory support was conducted in 4 cases.Rupture of the parietal pleura occurred in 3 cases (7.7％),cerebrospinal fluid leak in 1 case (2.6％),and pulmonary infection in 1 case (2.6％).Conclusion One-stage posterior VCR is effective in the treatment of severe and rigid spinal deformity.However,the perioperative complications,especially the neurological complications are common.The risk factors of neurological complications include preoperative neurological compromise,degree of kyphosis and the age of patients.
