To study the clinical characteristics and surgical treatment of congenital scoliosis with diastematomyelia, four patients were found to have scoliosis with diastematomyelia by CT and MRI.The first step of surgery was to excise the osteal compartion in spinal cord, the second step was the posterior scoliosis correction and fusion after two weeks. All the patients had successful surgery. The body height of the patients increased 4 75cm and the Cobb angle deceased 43? in average. No complication was found in the nervous system. This method is very effective, and is worth popularizing its application.

[ABSTRACT]AIM:Toinvestigatetheeffectofhypoxiacombinedwithexercisetrainingonmitochondrialcon-tent, and the role of mitochondrial biogenesis and mitophagy in this process .METHODS:Male Sprague-Dawley rats were randomly divided into 4 groups:normoxia control (NC) group, normoxia+training (NT) group, hypoxia+control (HC) group, and hypoxia+training (HT) group.The hypoxic animals were housed in normobaric hypoxic tent (11.3 % oxy-gen) for consecutive 4 weeks.The exercise training animals were exercised on a motor-driven rodent treadmill (5°) at a speed of 15 m/min, 60 min/d, 5 d/week for 4 weeks.Mitochondrial membrane potential was determined using JC-1 fluo-rescent probe .ATP synthesis capacity was determined using a bioluminescence technique .The protein expression of cyto-chrome C oxidase IV (COXIV), voltage-dependent anion channel-1 (VDAC-1), peroxisome proliferator-activated receptor gamma cofactor 1 alpha (PGC-1α), mitochondrial transcription factor A (Tfam),Bcl-2/adenovirus E1B 19 kD-interacting protein 3 (Bnip3) and beclin-1 in the muscles was detected by Western blotting .RESULTS:Compared with NC group, hypoxia attenuated mitochondrial membrane potential , ATP synthesis capacity , and the expression of COXIV , VDAC-1, PGC-1αand Tfam.Furthermore, hypoxia increased the expression of Bnip 3 and beclin-1.Compared with HC group , the exercise training elevated mitochondrial membrane potential , ATP synthesis capacity , and the expression of COXIV , VDAC-1, PGC-1α, Tfam, Bnip3 and beclin-1.CONCLUSION:A combination of reduced mitochondrial biogenesis and increased mitophagy seems to be responsible for the decrease in mitochondrial content after hypoxia .Exercise training with hypoxia elevates mitochondrial content and function in hypoxia , which may be mediated by appropriate increase and co-reg-ulation of mitochondrial biogenesis and mitophagy .

This study is to develop a sensitive method by using reversed-phase high performance liquid chromatography coupled with UV detector (HPLC-UV) to simultaneously determine four bioactive compounds, iriflophenone 3-C-beta-D-glucoside, iriflophenone 3,5-C-beta-D-diglucoside, mangiferin, and iriflophenone 2-O-alpha-L-rhamnoside in the leaves of Aquilaria sinensis. An Agilent Zorbax SB-C, column (4, 6 mm x 250 mm, 5 microm) was used, and the gradient elution was performed with mobile phase of 0.1% aqueous phosphoric acid and acetonitrile at a flow rate of 1 mL x min(-1). The detection wavelength was 280 nm, and the column temperature was 25 degrees C. The four marker compounds were well separated with good linearity (R2 > 0.9990), precision, stability and repeatabili y. The-recovery rates were in the range of 98.80%-101.39%. For 15 branch of the leaves, the contents of iriflophenone 3-C-beta-D-gluoside, iriflophenone 3,5-C-beta-D-diglucoside, mangiferin, and iriflophenone 2-O-alpha-L-rhamnoside were between 0.41-14.48, 0.72-3.85, 4.30-29.07, 0.24-5.06 mg, respectivley. This method is precise, accurate and reliable, which provides an efficient way for the quality control of the leaves of A. sinensis. This will promote the comprehensive usage of this plant.

Objective To determine the effect of omental flap wrapping of pancreaticoduodenectomy on postoperative pancreatic fistula and intra-abdominal bleeding in patients undergoing pancreaticiduodenectomy through meta-analysis of published studies.Methods Articles about whether omental flap wrapping could prevent postoperative pancreatic fistula and intra-abdominal bleeding were searched in databases of MEDLINE,PUBMED and EMBASE.14 English article were found and according to including and excluding criteria,4 eligible articles with a total of 2971 patients were selected.Random effects model was used to analyze odds ratios and 95％ confidence intervals (CIs).Results 1129 patients were in omental wrapping group,and 1842 patients in nonomental wrapping group.Omental roll-up during pancreaticoduodenectomy could not prevent postoperative pancreatic fistula (OR =0.81,95 ％ CI 0.40～1.63,P＞0.05) or postoperative abdominal bleeding (OR=0.67,95％ CI 0.28～1.59,P＞0.05).The sensitivity analysis showed the pancreatic fistula rate was lower in the nonomental roll-up group than that in the omental roll-up group (OR=1.24,95％ CI 1.03～1.50,P＜0.05).Conclusions Omental wrapping can not decrease the risk of pancreatic fistula and abdominal bleeding after pancreaticoduodenectomy.Further randomized controlled trials are needed to identify the effect of omental wrapping technique for pancreaticoduodenectomy.

In this study, the flow injection (FI) technology combined with the unique step wise multiple ions monitoring scanning (step-wise MIM) mode of Qtrap-MS was first established for the identification and discrimination of eight Murraya species. It only takes 5 min for each sample to detect approximate 600 compounds. The characteristic MS chromatograms of eight Murraya plants were analyzed by Analyst and SIMCA-P. The results of PCA showed that sect. Murraya and sect. Bergera were clearly divided into two categories, suggesting that there is difference in the chemical compositions between these two groups. Further detail analysis of the MS data could realize the preliminary structure elucidation of the component types contained in different plants. The main components in M. exotica and M. alata are coumarins, and polymethoxyflavones are rich in M. paniculata, while carbazole alkaloids are the major ones in sect. Bergera plants. The results are consistent with our previous comprehensive analysis of the chemical components of Murraya species. In conclusion, our research confirmed that FI-Qtrap-MS technology can be used for rapid identification and differentiation of similar plant species, providing reference for chemical taxonomy and a new method for the quality evaluation of medicinal materials.

OBJECTIVETo explore the effect of peimine on excision repair cross-complementation 1 (ERCC1) mRNA and lung resistant protein (LRP) expressions in A549/cisplatin (DDP) multidrug resistance (MDR) cell line.

METHODSLung cancer A549/DDP cells were cultured in vitro.Cells at logarithmic growth phase were divided into 4 groups, i.e., the blank control group, the DDP group, the ligustrazine group (DDP+ligustrazine), the peimine group (DDP + peimine). After 48-h drug action, ERCC1 mRNA expression was detected by RT-PCR and LRP expression detected by cell immunofluorescence.

RESULTSThere was no statistical difference in expression levels of ERCC1 mRNA and LRP between the DDP group and the blank control group (P > 0.05). Compared with the DDP group, expression levels of ERCC1 mRNA and LRP obviously decreased in the ligustrazine group and the peimine group (P < 0.05). They were obviously lower in the peimine group than in the ligustrazine group (P < 0.05).

CONCLUSIONSPeimine could reverse MDR of A549/DDP cell line. Its mechanism might be associated with down-regulating ERCC1 mRNA and LRP expression levels.

Objective Cervical radiculopathy treatment experts' consensus to establish radiculopathy type by using the modified Delphi method. Methods Use document retrieval method to review information and articles about the treatment guidelines and articles of cervical radiculopathy including domestic and international areas, established a protocol about clini?cal consensus of the treatments for cervical radiculopathy. This protocol included 23 questions (the effective proportion of non?operating therapy, neck immobilization, physiotherapy, pharmacologic treatment, surgical indications, contraindications, anteri?or surgical decompression, anterior surgical implants). We performed a modified Delphi survey in which current professional opinions from experienced experts, representing from almost all of the Chinese provinces, were gathered. And then we modi?fied the protocol according to those professional opinions. Three rounds were performed and finally we established consensus. Consensus was achieved with ≥70% agreement. Results The panel included 30 experienced experts. The recycling question?naire's quantity of three rounds were 30(100%), 24(80%) and 16(53.3%) respectively. After three expert assessments, there were 18 questions which achieved with≥70%agreement and these questions accounted for 64.3%(18/28) of all the questions. Consen?sus of the treatments for cervical radiculopathy was reached on 7 aspects, including:the effective proportion of non?operating thera?py (1 question), neck immobilization (1 question), physiotherapy (1 question), pharmacologic treatment (5 questions), surgical indi?cations (3 questions), contraindications (4 questions), surgery (3 questions). Conclusion This modified Delphi study had reached a consensus concerning several treatment issues on cervical radiculopathy which had strong representativeness of experts and good convergence of opinions. In the absence of high?level evidence, at present, these experts' opinion findings will guide health care providers to define appropriate treatment in their regions. Areas with no consensus provide excellent insight for future research.

Metabonomics was employed to investigate the effect of Angelica sinensis volatile oil (ASVO) to the endogenous metabolites of normal rats, and to reveal the possible ways of metabolism in rats caused by ASVO. The fifty male Waster rats were randomly divided into five groups (each consists of 10 rats), such as control group, high dose group of ASVO, middle dose group of ASVO, low dose group of ASVO, and Aspirin group. They were given 0.9% saline, 0.352 mL x kg(-1) ASVO, 0.176 mL x kg(-1) ASVO, 0.088 mL x kg(-1) ASVO and ASP respectively with the equal volume of 0.2 mL. Drugs and vehicle were given for 3 successive days. The urine was collected at 12, 24, 36, 48 h after modeling with metabolic cages. Rat urine metabolic fingerprint in different stages was analyzed using GC-MS, based on which the principal component analysis (PCA)and orthogonal partial least-squares discriminant analysis (OPLS-DA) models were established for metabonomic analysis. Potential biomarkers were screened by using variable importance in the projection (VIP) and T test. It was revealed that the middle dose of ASVO at 36 h induces a substantial change in rat urine. Compared with control group, seven kinds of endogenous metabolites in ASP group and ASVO group change significantly (P < 0.05), among which aconitic acid, succinic acid, citric acid, alpha-ketone glutaric acid, glycine and malic acid content had an upward trend (P < 0.05) and prostaglandin content had a downward trend (P < 0.01). The mechanism of ASVO and ASP have the similarity. It is likely that ASVO intervenes the metabolic process by affecting the energy, amino acid and lipid metabolism. Our work also indicates that rats administrated with ASVO can increase the energy metabolism of the body, induce the production of inflammatory substances and strengthen the body's immune ability. The result has also provide a proof for futher interpret ASVO pharmacological effects.
