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

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 investigate the mRNA and protein expressions of Nav 1.1 and Nav 1.2 in hippocampus following traumatic brain injury ( TBI) in rats.Methods After the lateral fluid percussion model was established in adult male Sprague Dawley rats,the rats were sacrificed at 2,12,24 and 72 hours after percussion and collected ipsilateral hippocampus for detecting mRNA and protein expressions of Nav 1.1 and Nav 1.2 by means of fluorescent quantitation RT-PCR,Western blot and immunofluo rescence staining.Results The mRNA expressions of Nav 1.1 and Nav 1.2 were significantly down-regulated (P<0.01) in hippocampus and reached the lowest level at 2 hours following TBI.The protein expression of Nav 1.1 was significantly down-regulated (P<0.01) but recovered near to level of control group at 72 hours after TBI.While there was no statistical difference on protein expression of Nav 1.2 in hippocampus after TBI compared with control group (P>0.05).Conclusion TBI induces significant down-regulated mRNA and protein expressions of Nav 1.1 in the hippocampus,which may be one of molecular mechanisms for functional alternation of sodium channels and excitotoxic action following TBI.

[Objective]This study was designed to determine growth inhibition of diallyl trisulfide(DATS)in human prostate cancer cells by inducing apoptosis and further to investigate the mechanism underlying such effect.[Methods]Growth inhibition by DATS was estimated by the tetrazolium(MTr)assay.Apoptosis induction in DATS-treated cells was assessed by fluorescence microscopy analysis of cells with condensed and segmented nuclei following staining with DAPI and flow cytometric analysis of cells with sub-G1 DNA content following staining with propidium iodide.Protein levels of apoptosis regulating proteins were determined using western blot.The activity of caspase-3 was measured using a colorimetric assay.[Result]DATS showed tumor growth inhibition in a time-and dose-dependent manner,IC_(50) of DATS was 14 μmol/L at 72 h.DATS evoked apoptosis as confirmed by cell morphology and by the analysis of flow cytometry.The expression of Bcl-2 and Bcl-xL,the apoptosis-suppressing proteins,was more down-regulated.The activity of caspase-3 was enhanced by DATS.[Conclusion]DATS inhibits growth of prostate cancer cells by inducing apoptosis in association with down-regulation of Bcl-2 and Bcl-xL and activation of caspase-3.

Objective To gain experimental data about breeding Musca domestica larvae by pig manure and to evaluate the effects and cost-benefit of feeding hens with larvae instead of fish powder. Methods The concentration of fatty acids and trace elements in the larvae bred with man-made fodder or pig manure were measured. The quality of eggs produced by hens fed with the larva powder or fresh larvae was investigated. Results The contents of trace elements (Ca,Fe,Cu,Zn,Se) of the larvae bred with pig manure were higher than those with man-made fodder(P0.05). Conclusion Breeding Musca domestica larvae with pig manure could produce good larva protein and reduce the expenses. The quality of the egg produced by the hens fed with larvae is as good as the quality of common eggs.

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.
