Objective To investigate the feasibility of percutaneous transforaminal endoscopic spine system in thoracic discectomy for disc herniation. Methods One patient with thoracic disc herniation involved the level of vertebral segment in T11/12 was treated with percutaneous transforaminal endoscopic spine system and followed up for 1 month. The targeted puncture was performed under local anesthesia and fluoroscopic guidance with patient in prone position. The foramen of T 11/12 was enlarged gradually with four trephinations, and the working cannula was inserted transforaminal into the canal. Then the herniation was exposed and removed with full endoscopic technique, including the loosen nucleus pulposus. The dural sac was exposed and released adequately. Drainage was placed during operation. Results The procedure was successfully carried out and the dural sac was completely released. The drainage was removed in the second day of operation. The patient could walk in the third day after operation with obvious relief of back and leg pain. At the follow-up of one month postoperation, the visual analogue scale of leg pain decreased from 8 to 1, and the Oswestry disability index (ODI) decreased from 64 to 4. According to MacNab scale, excellent result was acquired. Conclusion There is the feasibility of the percutaneous transforaminal endoscopic spine system in thoracic discectomy for disc herniation. It is a good minimal invasive technique with good results and high technical requirements for surgeons.

Objective To compare the safety and effectiveness of duodenum-preserving pancreatic head resection (DPPHR) with pylorus-preserving pancreaticoduodenectomy (PPPD) in the treatment of chronic pancreatitis with a pancreatic head mass.Methods Medline,Biosis,Cochrane Library,Science Citation Index Database,CBM Database,Wan Fang and CNKI were searched systematically.The bias risk of the included trials was assessed according to the assessing tools as suggested by the Cochrane Handbook.Review Manage 5.2 was used to perform the statistical analysis.Results 7 RCTs with 226 patients were included in the meta-analysis which showed that there were no significant differences between PPPD and DPPHR in overall postoperative morbidity,postoperative hospital stay,complete pain relief,pancreatic fistula,exocrine insufficiency,symptom score at 5 to 7-year follow-up,and quality of life score at 14 to 15-year follow-up (P ＞ 0.05).While DPPHR had significant superiorities in operation time,blood replacement,delayed gastric emptying,occupational rehabilitation after the operations,weight gain,quality of life score at 1 to 2-year follow-up,symptom score at 5 to 7-year follow-up,and physical functioning score at 14 to 15-year follow-up.Conclusions DPPHR is more favourable than PPPD in reducing the use of blood replacement,shortening operation time,delayed gastric emptying,occupational rehabilitation after the operations,weight gain,physical functioning,and in improving quality of life of patients.

In order to identify virulence factors of the pathogen, the outer membrane proteins of virulent and avirulent strains of Riemerella anatipestifer were compared by a proteome analysis. Three protein spots differentially expressed between the two strains were observed by 2-DE gels, and were further analyzed using in gel tryptic digestion and peptide mass fingerprinting. Three proteins were identified. W1 was Hsp20, W2 and W3 were transposon. Although the exact role of these proteins has not been characterized, the exclusive expression in virulent strain may indicate that they play an important role in the pathogenesis of Riemerella anatipestifer infection. Although only two virulence factors identified, it opens a path to the further analysis of virulence factors of Riemerella anatipestifer.

Objective To explore the expression and clinical significance of microRNA (miR)-155 and miR -222 in plasma of patients with ventricular septal defect(VSD),and to analyze the possible mechanism.Methods A total of 20 children with VSD who received treatment at the Department of Cardiovascular Surgery from August 2012 to June 2013 were enrolled (the VSD group)and 15 patients with fracture (the control group).The plasma miR -155 and miR -222 expression levels were measured by real -time quantitative reverse transcription -polymerase chain reaction (RT -qPCR).The potential target genes of miR -155 and miR -222 were predicted by using 3 current-ly available prediction programs,including TargetScan,mirbase and Miranda,and the signaling pathway of miRNA was predicted by Pathway -express analysis.Results Compared with the control group,the expression levels of miR -155 (P =0.033)and miR -222(P <0.001)in the VSD group decreased significantly;miR -155 and miR -222 predic-ted target genes included 74 and 50,respectively.The Pathway -express analysis indicated that 7 signaling pathways played important roles in the occurrence of fetal VSD,including signaling pathways for heart development,such as:mito-gen -activated protein kinase(MAPK)signaling pathway.Conclusions The expression levels of plasma miR -155 and miR -222 in VSD were significantly decreased.The target genes were related to signaling pathways for heart deve-lopment (MAPK signaling pathway),which indicates that miR -155 and miR -222 may be involved in the pathological process of VSD,and may serve as an independent evaluation indicator for the diagnosis of VSD.

Signal transducer and activator of transcription 3 (STAT3) is an important regulatory factor of cell proliferation and metastasis, involved in the occurrence and development of a variety of malignant tumors, and it is one of the hot spots in the research of targeted anti-tumor drugs. Our group screened a novel benzobis (imidazole) structure small molecule compound LZJ541 through the screening model of Janus kinase (JAK)/STAT3 pathway inhibitors, which has definite STAT3 inhibitory activity. We examined the effect of LZJ541 on the proliferation of HepG2 and PC-3 cells by MTT assay in vitro, detected the effect of LZJ541 on the expression of STAT3-related proteins in HepG2 cells by Western blot, and measured the effect of LZJ541 on the apoptosis and cell cycle arrest of HepG2 cells via flow cytometry. The results indicated that LZJ541 significantly inhibited the activation of STAT3 signaling pathway and restrained the proliferation of HepG2 cells. Its half maximal inhibitory concentration (IC₅₀) was 13.8 μmol·L^-1, which was much lower than that of PC-3 cells (with low STAT3 expression, IC₅₀: 41.99 μmol·L^-1), LZJ541 can also inhibit the phosphorylation of STAT3 in HepG2 cells, thereby inducing apoptosis and cycle arrest and then exerting anti-tumor effects. In conclusion, LZJ541 has a certain anti-tumor effect in vitro, which provides an experimental basis for the development of new STAT3-targeted anti-tumor drugs around this kind of compounds.

Forty-eight men with normal glucose tolerance were divided into fatty liver disease ( NAFLD, n =23 ) and non-NAFLD (n =25 ) groups. The blood glucose excursion was evaluated by continuous glucose monitoring system. The results showed that the mean amplitude of glucose excursion[MAGE, (2. 17± 1.13 vs 1.45±0. 42 )mmol/L]and standard deviation of blood glucose[SDBG, (0. 88 ±0. 45 vs 0. 61 ±0. 21 ) mmol/L]were significantly higher in NAFLD group than in non-NAFLD group( both P＜0. 05 ). MAGE and SDBG were positively correlated with body mass index, waist circumference, and the increased value of plasma glucose 0. 5 h after glucose loading( △G30,all P＜0. 05 ). In multiple regression analysis, △G30, waist circumference, and age were significant independent predictors for MAGE( P＜0. 05 or P＜0. 01 ). △G30 and waist circumference were significant independent predictors for SDBG( P＜0. 05 or P＜0. 01 ).

Objective:To study the clinicopathologic characteristics and the prognostic factors of triple negative breast cancer,and to study the correlation between clinicopathologic features and EGFR expression.Methods:Clinical characteristics and prognosis of 200 breast cancer patients diagnosed between 1997 and 2004 were reviewed.The paraffin embedded tissues were selected and tissue microarray blocks were made.Immunohistochemical staining was used to evaluate the expression of ER,PR and HER2 for breast cancer molecular type.EGFR expression was evaluated to analyze its correlation with the clinical characteristics and prognosis.Results:Fourty-two cases(21%)of 200 were triple negative breast cancer(TNBC).There was no significant difference between TNBC and non-TNBC in clinicopathologic parameters such as age,tumor size,clinical stage,and lymph node status.However,there was significant difference in histological category and menostasis status between the two groups(P<0.05).Among TNBC,17 0f 42 died during the follow-up(the overall suivival rate was 59.52%),while 26 0f 158 non-TNBC died(the overall survival rate was 83.54%).EGFR was significantly overexpressed in TNBC(69.05%)and it was associated with lymph node status and histological category.Conclusion:Although the incidence of TNBC is low,it has a poorer prognosis than other subtypes.EGFR is highly expressed in TNBC and may serve as a prognostic index and an important therapatic target for breast cancer.

Recently, the D'Amico classification system is widely used for the risk stratification of prostate cancer (PCa) , although no consensus has been reached for the definition of high-risk PCa. This system defines high-risk PCa as a prostate-specific antigen (PSA) level > 20 ng/ml, a Gleason score of 8-10, or a clinical stage ≥ T2c. Because high-risk PCa is prone to recurrence and metastasis after treatment, a proper initial therapy plays a crucial role. Currently, radical prostatectomy and radiation therapy are considered to be two most important options for the initial treatment of high-risk PCa although it remains controversial which is better.

Objective To investigate the effect of anterior percutaneous endoscopic discectomy (APECD) and open-door laminoplasty (ODLP) through hybrid surgery in the treatment of multisegmental cervical stenosis and giant disc herniation. Methods This study involved 3 patients with multisegmental cervical stenosis and giant disc herniation confirmed by MRI. Among them, there were 2 males and 1 female, with ages from 56-61. All patients showed significant paresthesia or weakness, and were treated between September and November 2016. The surgery was performed by first the ODLP that made spinal cord back shift, and then APECD for the second step. The visual analog scale (VAS) and neck disability index (NDI) were assessed before and after operation. Results The VAS and NDI scores were improved two weeks after operation. No adverse events like spinal cord injury and vascular injury were found during the operation. After operation, no patients were found incision infection, hematoma formation, cerebrospinal fluid leakage, dysphagia, trachyphonia and so on. Conclusion The hybrid surgery of APECD and ODLP for the treatment of the multisegmental cervical stenosis and giant disc herniation can not only decompress the nerve safely and improve the function, but also preserve cervical intervertebral disc and motion segments, therefore delaying the degeneration of adjacent segments with clinical significance.
