BACKGROUND:Vertebral column resection is the frequently mentioned spinal orthopaedic concept. Due to the high requirement of the operation skil , difficulty and more complications, the previous studies have reported from different aspects, and many researchers have focused on the analysis of complications, that may be related with the procedure and manner. OBJECTIVE:To analyze the efficacy and complications of posterior vertebral column resection combined with titanium screw rod fixation for the treatment of severe spinal deformity. METHODS:We retrospectively analyzed 48 patients with severe spinal deformity who treated with posterior vertebral column resection and titanium screw rod fixation, with an average removal of 1.6 vertebral. The patients were fol owed-up for 15-64 months. The Cobb angle (coronal plane and sagittal plane) of the patients before treatment, after treatment and in the final fol ow-up was analyzed, and the relative complications of the surgery were analyzed. RESULTS AND CONCLUSION:The patients with spinal deformity were divided into five categories, included kyphoscoliosis (n=11), severe scoliosis (n=20), congenital spinal deformity (n=4), spherical kyphosis (n=3), and angular kyphosis (n=10). The average coronal plane deformity angle of the patients was corrected from 84° preoperation to 35° postoperation, with the total correction rate of 54%. The average sagittal plane deformity angle was corrected from 90° preoperation to 42° postoperation, and the sagittal plane Cobb angle was decreased for 48°. The mean operation time was 545 minutes (204-1 355 minutes), the intraoperative blood loss was 1 610 mL (50-8 244 mL), and the average blood loss was 65%. After treatment, 31 cases had complications, including 13 cases of intraoperative neurological dysfunction (observed through electrophysiological monitoring and wake), permanent neurological dysfunction did not occur after timely treatment. The posterior vertebral column resection and titanium screw rod fixation can obtain better effect in the treatment of severe spinal deformity, but the procedure has high complications and is difficult for operation.

In order to separate chiral D-phenylalanine from L-phenylalanine,the enzyme catalytic method by papain and immobilized papain were used in this investigation.It indicated that the yield rate of N-acetyl-DL-phenylalanine synthesized from DL-phenylalanine was 88.7%.The ionic strength was the strongest influencing factor in the synthesis of N-acetyl-L-phenylalanylaniline by both papain and immobilized papain on sodium alginate-ehitosan(IPSAC).But the reaction temperature was the strongest influencing factor in the synthesis by immobilized papain on nylon cloth(IPN).The ionic strength and the pH were the important influencing factors in the synthesis.The yield rates of the best synthesis system of N-acetyl-L-phenylalanylaniline by papain,IPSAC,IPN were 61.2%,54.7%,36.3%,respectively.The yield rate of L-phenylalanine from N-acetyl-L-phenylalanylaniline hydrolyzation was 59.2%.The optical purity of the product was 96.6%.The vield rate of D-phenylalanine from N-acetyl-D-phenylalanine hydrolyzation was 61.7%.The optical purity was 95.7%.

The enzymatic synthesis of endomorphins were carried out by immobilized papain on sodium alginate-chitosan (IPSAC). The reaction has been carried out in two steps. First, Trp-Phe-NH2 was obtained by Boc-Trp-OH coupling with Phe-NH2 using IPSAC catalyst in microaqueous acetonitrile system with a 27.8 % yielding as determined by high performance liquid chromatography (HPLC). The catalytic properties of IPSAC were examined by studying the dependence of pH, ionic strength, solution content, reaction temperature,enzyme loading and reaction time over the yields. The results of orthogonal experiments indicated that pH was the most significant factor that influenced this synthesis. Second, Boc-Tyr-Pro-OMe and Trp-Phe-NH2 were suspended into the microaqueous acetonitrile to produce Tyr-Pro-Trp-Phe-NH2 (endomorphin-1) with a 35.2% yield.

Objective To explore the relationship between different blood glucose levels and new carotid artery plaques.Methods A total of 5 440 participants met the inclusion criteria were selected stratified randomly from the 101,510 serving and retired workers of Tangshan Kailuan Company who participated the health examination from 2006 to 2007.The follow-up health examination were respectively preformed from 2010 to 2011 and from 2012 to 2013 which included carotid ultrasound for these 5 440 participants.The 5 440 participants were divided into three groups (ideal blood glucose group,impaired fasting glucose group and diabetic group) according to their fasting glucose levels in 2010-2011 examination.Multivariate Logistic regression analysis was used to analyze the risk factors of new carotid artery plaques.Results Among 5 440 subjects,participants whose FPG,ultrasound data incomplete and ultrasound detection of carotid plaques during the 2010-2011 health examination were excluded,then 3 084 participants were included in this study,among them,175 participants who did not participate the 2012-2013 health examination and 561 participants whose carotid plaque ultrasound data incomplete were excluded.Thus,a total of 2 348 participants were included in the present analysis.The total detection of new carotid artery plaque rate was 15.0％ (352/2 348) after 2 years of follow-up.The detection of new carotid artery plaque rate in normal glucose group(n =1724),impaired fasting glucose group(n=464) and diabetic group(n=160) were 14.2％(245/1 724),14.9％(69/464) and 23.8％(38/160),respectively.The diabetic group was higher than that of the ideal blood glucose group and the impaired fasting glucose group,the difference was statistically significant(P＜0.05).Impaired fasting glucose group and diabetic group had an increased risk of new carotid artery plaque compared with those in ideal glucose group(OR =0.924,95％CI 0.691-1.235 and OR =1.733,95％CI 1.107-2.713,respectively),the difference was statistically significant(P＜0.05).After adjusted for the other risk factors,with the risk-adjusted ratio (OR =1.117,95％CI 0.824-1.513 and OR =1.393,95％CI 0.872-2.226).Conclusion The detection of new carotid artery plaque increase in the diabetic group.However,after adjustment for other risk factors associate with emerging danger of new carotid artery plaque is no significant difference.This requires more long-term follow-up study of a large sample to be further confirmed.

AIM:We generated transgenic mice of NKCC1-/-(homozygous mutant),NKCC1+/-(heterozygous)and NKCC1+/+(wild-type)that have a targeted disruption in the NKCC1 gene to investigate the role of Na-K-2Cl(NKCC1)channel in auditory function of the inner ear.METHODS:Hearing threshold and endocochlear potential(EP)were measured in the NKCC1-/-,NKCC1+/-and NKCC1+/+ mice by auditory brainstem response(ABR)and EP recordings,respectively.The inner ears of the mice were removed and examined morphologically with the light microscope.RESULTS:The auditory function of NKCC1+/+ mice was normal,the mean value for ABR thresholds in response to click sound was [(23.13?3.78)dB,SPL],EP was(98?16)mV.The mean value for ABR thresholds to click sound was elevated in NKCC1+/-mice [(38.49?12.29)dB,SPL],relative to that significantly increased in NKCC1+/+ mice(P

BACKGROUND:Spine minimaly invasive technique through foraminal mirror is the method to treat lumbar disc herniation with minimal wound. This technique can be conducted under local anesthesia, and does not need to resect the smal joint or destroy the vertebral plate, and has smal damage to the spine. OBJECTIVE: To explore the short-period effects of transforaminal endoscopic spine system for adjacent-segment degenerative changes-caused low back pain after lumbar fixation and fusion. METHODS:A total of 31 patients with degenerative changes after posterior lumbar bone graft fusion fixation, who required secondary surgery, were enroled in this study, including 23 males and 8 females, at the age of 45-81 years old. The postoperative time was 1.1-5.7 years. There were 3 cases of L3-4 single segment, 15 cases of L4-5 single segment, 8 cases of L5S1 single segment, and 5 cases of multi-segment. These patients were treated with transforaminal endoscopic spine system, and folowed up for 6 months. Visual Analogue Scale score and lumbar function Japanese Orthopedic Association score were observed. RESULTS AND CONCLUSION: Lumbar and leg pain symptoms were relieved noticeably during the operation. The patient could walk immediately after the surgery, and the postoperative recovery was quite satisfactory. Visual Analogue Scale score was lower immediately, 1, 3 and 6 months after treatment compared with pre-treatment. Lumbar function Japanese Orthopedic Association score was higher immediately, 1, 3 and 6 months after treatment compared with pre-treatment. Results verify that transforaminal endoscopic spine system for degenerative changes after posterior lumbar bone graft fusion fixation has some advantages such as high safety, short operation time, less hemorrhage, less complications, rapid restoration and easily accepted by patients.

AIMTo investigate the protective effects of adenovirus-mediated hepatocyte growth factor (Ad-HGF) on injury of rat cortex neurons induced by in vitro serum-free culture.

METHODSFlow cytometry was used to assay the transfection rate of rat cortex neurons infected by adenovirus-mediated green fluorescent protein(Ad-GFP) at different multiplicity of infection (MOI) to find out the best MOI in experiment. ELISA was used to elucidate the expression patterns of cortex neuron. Neutral red stain and PI-Hoechst 33342 double stain were used to compare the viability of cortex neurons, which were cultured in serum-free medium for 6 h, 12 h, 24 h and 48 h respectively, among the Ad-HGF transfected group, the Ad-GFP transfected group and the control group.

RESULTSIt was found that when MOI was 50 PFU per cell, a transfection rate as high as 99.3% was maintained and Ad-HGF was able to express in cortex neurons effectively and persistently. In addition, the death rate and apoptotic rate of cortex neurons (infected 2 hours after seeding) cultured in serum-free medium for 12 h in Ad-HGF transfected group was significantly lower than that in both the Ad-GFP group and the control group (P < 0.05).

CONCLUSIONAd-HGF plays a protective role against in vitro serum-free culture induced injury on rat cortex neurons infected 2 hours after seeding. Though its effects on rat cortex neurons infected 5 days after seeding are not so remarkable, Ad-HGF also has the potential to protect cortex neurons from serum-free culture induced injury.
