Objective To compare treatment and efficacy of thoracolumbar fractures by using three different screw fixations:traditional approach,the vertebral side clearance into the road and percutaneous pedicle. Methods A total of 82 single segmental thoracic lumbar fractures cases hospitalized from March 2011 to March 2014 ,with male 67 cases ,female 15 cases ,and average age(33.7+/-12.5)years old. Patients were randomly divided into three groups:traditional approach group (n = 23),operation through paraspinal muscle gap group (n = 30),percutaneous group(n = 29). These following indicators will be compared in three groups:duration of operation ,intraoperative blood loss ,intraoperative fluoroscopy time ,postoperative flow ,VAS scores before and after operation and Oswestry disability index , difference of spinal sagittal position Cobb′s Angle. Results Compared with the traditional approach group ,operation through paraspinal muscle gap group and percu-taneous group have obvious advantages in duration of operation,intraoperative blood loss,postoperative flow,VAS scores before and after operation ,the Oswestry disability index. Additionally ,above mentioned three surgical methods could recover kyphosis deformity ,and there was no statistically significant difference among three groups (P > 0.05). Conclusion In the treatment of monosegmental thoracolumbar fractures ,compared with traditional approach ,operation through paraspinal muscle gap and percutaneous pedicle screw internal fixation have more advantages which includes fewer trauma,less bleeding,faster recovery and lower incidence of postoperative low back pain.

Objective:To identify pathogenicity of the potential splicing variants in two Chinese Han patients with osteogenesis imperfecta.Methods:Genomic DNA was extracted using the conventional phenol-chloroform method; whole exome sequencing (WES) was used to analysis the disease-related variants in the two probands; Minigene assay was used to identify pathogenicity of the variants found in the patients' genome that possibly affect RNA splicing.Results:Two potential splicing variants, c.858+1_858+5delGTAAG in intron 12 of COL1A1 and c.1405-7C>T in intron 24 of COL1A2, were found in proband 1 and proband 2, respectively. In addition, a missense mutation, c.2972G>T (p.G991V) in exon 45 of COL1A2, was detected in proband 2. Minigene assay revealed that the variant in proband 1 caused the skipping of exon 12, while the variant in proband 2 did not lead to aberrant splicing. G199 of the COL1A2 in proband 2 was a highly conserved amino acid site, and the results suggested that c.2972G>T (p.G991V) may be the real pathogenic variant by the means of bioinformatics analysis.Conclusion:The variant c.858+1_858+5delGTAAG in COL1A1 was a causative variant that led to OI in proband 1, while the missense variant c.2972G>T (p.G991V) in COL1A2 was the cause of OI in proband 2, instead of the variant c.1405-7C>T. Minigene assay for potential splicing variants detected by WES could not only validate the pathogenicity of the candidate variants and enrich the mutation spectrum of OI, but also lay the foundation for patients' prenatal diagnosis and subsequent mechanism research.

Objective To investigate the risk factors of slow coronary flow (SCF) phenomenon; To study the prognosis of SCF patients and analyze the high risk factors of adverse events by follow-up.Methods 17930 patients were analyzed retrospectively who had undergone routine coronary angiography because of suspected coronary artery disease at TEDA International Cardiovascular Hospital from January 2006 to December 2010.By Thrombolysis in myocardial infarction Frame Count method,236 patients with normal coronary artery but slow coronary flow were enrolled in the SCF group and 240 patients with normal coronary artery and normal coronary flow (40-50patients per year) were enrolled in the control group.After that,the risk factors leading to SCF were analyzed by the multivariate logistic regression analysis and all patients were followed up from March 2012 to April 2012 to know about the incidence of adverse events (acute coronary syndrome,malignant arrhythmia and sudden cardiac death) and the high risk factors leading to the adverse events.Results (1) Compared to the patients in the control group,the patients in SCF group have higher percentage of male (76.69％ vs.42.08％,P =0.000) 、rate of smokers (58.48％ vs.27.50％,P =0.000) 、BMI (26.78 ±3.75 vs.26.13 ±3.20,P =0.043) 、serum uric acid (344.90 ± 86.18 vs.304.43 ±76.44,P =0.000) 、serum creatinine (68.27 ± 15.10 vs.60.92 ± 13.17,P =0.000)、triglyceride (1.85 ± 1.23 vs.1.65 ± 0.81,P =0.037) but younger age and lower high density lipoprotein cholesterol (1.14 ± 0.28 vs.1.19 ± 0.30,P =0.048).(2) By multivariate logistic regression analysis,male,smoking status,hiah BMI and serum uric acid are all independent factors for SCF.(3) The SCF phenomenon noted in lvessel,2 vessels and 3 vessels accounted for 7.29％,26.04％,66.67％,respectively.(4) During the follow-up,2 patients with malignant arrhythmia and 1 patients with ACS were found in SCF group,no sudden cardiac death took place.None of the adverse events happened in the control group.Conclusions Younger male smokers are prone to have SCF,high BMI and serum uric acid are also independent factors for SCF; The SCF phenomenon is most common in three coronary arteries.Both malignant arrhythmia and acute coronary syndrome took place in the SCF group in the follow-up.

Abstract: Total RNA was isolated from Siraitia grosvenorii fruit by the method of modified Trizol, according to S. grosvenorii fruit characteristics of rich phenols, polysaccharide, oil and proteins. The OD260/280, OD260/230, RNA integrity (RIN) and yield of the total RNA with this method were 2.01, 2.02, 9.50 and 260 mirog.g-1, respectively. The open reading frame (ORF) of dehydroascorbate reductase (DHAR), named as SgDHAR, was cloned by rapid amplification of cDNA ends (RACE) and RT-PCR method from S. grosvenorii. The GenBank accession number for this gene is KC907731. The SgDHAR gene contains a full-length cDNA of 1,252 bp including ORF of 819 bp and encodes a predicted protein of 272 amino acids. The molecular mass is 30.217 7 kD and the isoelectric point is 8.76. Homology comparison showed that it shared 87% nucleotide sequence homology with Cucumis sativus. Expression patterns using qRT-PCR analysis showed that SgDHAR was mainly expressed in fruit and stem, followed by flower, and was lowest in root, while the expression level was 6.83 times in triploid. T than that in diploid. Therefore, SgDHAR gene may be involved in abortion of triploid seedless S. grosvenorii.

Objective To investigate the efficacy and safety of triple anti-platelet therapy (low-dose tirofiban plus aspirin and clopidogrel) comparing to dual anti-platelet therapy (aspirin and clopidogrel) in preventing stent thrombosis (ST) and major adverse cardiac events (MACE) within 30 days after implantation of drug-eluting stent (DES) in ACS patients.Methods A total of 2904 ACS patients treated with DES from March 2004 to November 2010 were enrolled for retrospective study.Of them,1145 patients were treated with dual anti-platelet therapy (DAT) and 1759 patients with triple anti-platelet therapy (TAT).The incidences of ST,MACE (cardiac death,urgent target vessel revasculanization and myocardial infarction) and side effects occurred within 30 days after PCI were compared between two groups by Fisher' s exact test.Results (1)Although there were significant differences in age,the degree of coronary stenosis,the number of smokers,diabetes,hyperlipidemia and coronary diffuse lesion between two groups,but these differences did not impact on the end point events showed by Cox analysis.The rest of the general condition of patients between two groups was no difference.(2) The incidence of ST as primary end point was lower in TAT group than that in DAT group (0.11％ vs.1.05％,P =0.0036),reducing the relative risk by 89.52％.In addition,the incidence of MACT as secondary end point was also lower in TAT group than that in DAT group (0.17％ vs.1.48％,P =0.0005),reducing the relative risk by 88.51％.Among the total,the incidences of cardiac death and urgent target vessel re-vascularization in TAT group were lower than those in DAT group with significant differences.However,there was no difference in the incidence of myocardial infarction between two groups.(3) Both two groups had no severe hemorrhage complication,the incidence of mild hemorrhage was similar in two groups (0.45％ vs.0.35％,P =0.6720).Nesides,the incidence of acute thrombocytopenia between two groups was also similar (0.45％ vs.0.09％,P =0.083).Conclusions The patients with ACS in the TAT group have significant lower incidence of ST and MACE than those in the DAT group within 30 days after PCI.While the risk of bleeding and the incidence of acute thrombocytopenia do not increase.

Objective: To observe the effects of moxibustion pretreatment on the protein expressions of epidermal growth factor receptor (EGFR), phosphorylation extracellular signal-regulated kinase 1/2 (p-ERK1/2) and activated protein-1 (AP-1), the key factors of extracellular signal-regulated kinase signaling transduction pathway in gastric tissue of rats with stress-induced gastric mucosal damage, and to discuss the mechanisms of moxibustion therapy in promoting the restoration of damaged gastric mucosa.
Methods: Thirty Sprague-Dawley (SD) rats were randomly divided into a normal group, a model group, and a moxibustion group using the random digits table, 10 in each group. Except the rats in the normal group, rats in the other two groups were used to make stress-induced gastric mucosal damage model using restraint and cold stress. Before modeling, rats in the moxibustion group were alternately treated with moxibustion at Zusanli (ST 36) and Zhongwan (CV 12), or Pishu (BL 20) and Weishu (BL 21), once a day, for a total of 8 d. Histological changes of gastric mucosa were observed under the light microscopy, the expression of gastric tissue p-ERK1/2 was detected by immunohistochemistry assay, and the protein levels of EGFR and AP-1 were measured by Western blots.
Results: Compared with rats in the normal group, gastric mucosal damage was more serious, and protein expressions of gastric tissue EGFR, p-ERK1/2 and AP-1 increased in the model group (P<0.01,P<0.05,P<0.05). Compared with rats in the model group, gastric mucosal damage was milder, and protein expressions of gastric tissue EGFR, p-ERK1/2 and AP-1 increased in the moxibustion group (allP<0.01).
Conclusion:Moxibustion at Zusanli (ST 36), Zhongwan (CV 12), Pishu (BL 20) and Weishu (BL 21) couldincrease EGFR, p-ERK1/2 and AP-1 expression levels in gastric tissue of stress-induced gastric mucosal damage rats, maintain the information transfer function of ERK signaling transduction pathway, and promote restoration of gastric mucosal damage.

Objective:To observe the clinical effect of wheat grain-sized cone moxibustion combined with fire needle therapy in the treatment of dorsal wrist ganglion (DWG). Methods:A total of 63 patients with DWG were randomized into a treatment group (n=32) and a control group (n=31). Cases in the control group were treated with fire needle therapy. Based on the therapy given to the control group, cases in the treatment group were additionally given wheat grain-sized cone moxibustion therapy. Then the therapeutic efficacies and recurrence rate were evaluated. Results:After treatment, the overall effective rate was 93.8% in the treatment group, versus 77.4% in the control group, and the between-group comparison showed a statistical significance (P<0.05); 6 months after the treatment, the recurrence rate in the treatment group was obviously lower than that in the control group (P<0.05). Conclusion:The long-term and short-term effects of wheat grain-sized cone moxibustion combined with fire needle therapy in the treatment of DWG are better than those of fire needle therapy alone, and therefore, worth popularizing.

To confirm the hypothesis that the high frequency sequences of high throughput sequencing are the terminal sequences of the bacteriophage genome. An adaptor of specific sequence was linked to the end of the bacteriophage T3 genomic DNA, which was then subject to high throughput sequencing; as a control, the same T3 genomic DNA without adaptor was also analyzed by high throughput sequencing. The sequencing results were examined with bioinformatics software. Similar high throughput sequencing technique was applied to analyze the genomic sequence of N4-like bacteriophage IME11. Bioinformatics study showed that the sequences tagged with adaptors were consistent with the high frequency sequences without adaptor labeling. Our analysis also indicated that the end of the T4-like phage genome had specific sequences instead of random sequences, disagreeing with the previous assertion. Evidences were provided that N4-like bacteriophage had a particular terminal sequence: the left end of the genome was unique while the right end was permuted. The high throughput sequencing technique was convenient and practical to be used to simultaneously detect the terminal sequence and the complete sequence of bacteriophage genome.

Endoscopic resection is currently accepted as a standard therapy for colon polyp because of its safety and efficiency. The indications for endoscopic resection have been expanded to treat mucosal colon cancer and submucosal tumor. The major complications of endoscopic resection are hemorrhage, perforation and post- polypectomy coagulation syndrome. Hemorrhage is the most common complication, and this can occur immediately following colonoscopic polypectomy or it can be delayed after completion of the procedure. Delayed hemorrhage usually occurs within 7 days and this can stop by itself or the hemorrhage can be controlled endoscopically in the majority of patients, with only the unusual and serious cases requiring transfusion, angiography and surgery. We experienced a case of delayed massive hemorrhage with hypotension that required transfusion 12 days after performing endoscopic resection for rectal carcinoid tumor. We report here on this case to provide a good example and to place emphasis on delayed massive hemorrhage after endoscopic resection.
