Long non-coding RNAs (lncRNAs) are deifned as transcripts longer than 200 nt without coding capacities. Although they were initially argued to be transcriptional by-products of RNA polymeraseⅡ, recent evidence suggests that lncRNAs have been associated with a spectrum of biological processes, and aberrant lncRNA expression may be a major contributor to tumorigenesis, progression and prognosis. This study summarizes the up-to-date studies on lncRNAs in urological neoplasms.

Objective: To observe the clinical therapeutic efficacy of treatment of prolapse of lumbar intervertebral disc with lumber vertebral traction plus Ding's Rolling Technique.Methods: 133 cases of prolapse of lumbar intervertebral disc were randomly divided into two groups.

The therapeutic efficacy in the treatment group was better than the control group.Conclusion: The clinical therapeutic efficacy treated with lumber vertebral traction plus Ding's Rolling Technique was better than simple lumber vertebral traction in treating prolapse of lumbar intervertebral disc.

The current status and important advances in multi-disciplinary treatment for advanced gastric cancer,including surgery,chemotherapy and radiotherapy,were reviewed in this article.An operative scheme based on the stage and biologic behavior of the tumor is adopted with the D_2 procedure combined with intraoperative peritoneal hyperthermic chemotherapy(IPHC) for stage Ⅱ and Ⅲ patients.Accurate preoperative staging is of utmost importance in making an appropriate therapeutic strategy.For patients with stage Ⅲ_B and Ⅳ gastric cancer,neo-adjuvant chemotherapy followed by cyto-reductive surgery,is helpful to prolong survival and improve the quality of life.Besides the 5-FU,cisplatin and doxorubicin based regimen,combination regimens employing newer generation cytotoxic agents including oxaliplatin,irinotecan,taxanes provided more promising efficacy.Postoperative chemo-radiotherapy is presently under investigation.

Objective To investigate indications of thoracoscopic resection of esophageal carcinomas. Methods A total of 75 patients with esophageal carcinomas underwent video-assisted thoracoscopic surgery (VATS) from July 1997 to July 2003. The dissection of the esophagus and radical resection of lymph nodes were performed using a right-sided VATS approach. Then the stomach was dissociated through an upper-abdominal incision and was pulled up for esophago-gastric anastomosis in the left neck. Results A conversion to open surgery was required in 3 patients, in 2 of whom the tumors had enroded into the hilum and the posterior wall of the heart, and in 1 of whom the azygous vein was ruptured. The operation time was 160~220 min, with the intrathoracic operation time accounting for 60~90 min. The postoperative blood loss was 300~400 ml. No surgery-related deaths were noted. Postoperative complications included 1 case of volvulus of stomach, 2 cases of anastomotic leakage, 1 case of anastomotic stenosis, and 1 case of chylothorax. Follow-up checkups in 60 patients for 3 months ~ 7 years (mean, 4 years) found 2 cases of supraclavicular lymph node metastasis and 1 case of abdominal lymph node metastasis. The 1-, 3- and 5-year survival rates were 85.0% (51/60), 51.7% (31/60) and 40.0% (24/60), respectively. Conclusions Video-assisted thoracoscopic resection of esophageal carcinomas is feasibly suited to patients with localized lesions at phaseⅠ or Ⅱ.

Objective To explore the clinical implications of the initial levels of serum uric acid (SUA) after admission in the critically ill patients with infection,and to investigate the relationship between SUA and prognosis of infection.Methods From January 2003 to April 2010,471 patients with infection were admitted to the ICU of Huashan Hospital,Fudan University,Shanghai.Data,including serum uric acid (SUA),serum creatinine,blood urea nitrogen (BUN) and other relevant laborartory results within 24hours after admission,were retrospectively analyzed.The distribution of uric acid was described.The t test was used to evaluate the relation between SUA and preexisting disorders.Patients with different level of SUA were classfied for further analysis.x2 test was used to examine the difference in the prognosis of infection.Results The mean initial level of SUA within 24 hours after admission was 0.232 ± 0.131 mmol/L and the median 0.199 mmol/L. Remarkable difference in initial levels of SUA were observed in patients with preexisting hypertension (t=-3.084,P=0.002),diabetes mellitus (t=-2.487,P=0.013),cerebral infarction (t=-3.061,P=0.002),renal insufficiency (t=-4.547,P＜0.01),central nervous system infection (t =5.096,P ＜ 0.01 ) and trauma (t =2.875,P =0.004).Serum uric acid was linearly correlated with serum creatinine and blood urea nitrogen (F =159.470 and 165.059,respectively; P ＜0.01).No statistical correlation was found between initial levels of SUA and prognosis of infection (x2=60.892,P=0.100).Conclusions There is no direct correlation between the initial levels of SUA afteradmission and the prognosis of infection in the critically ill patients.

Objective To investigate the protective effects of thalidomide on rats with acute necrotizing pancreatitis (ANP) and its mechanism. Methods Fifty four SD rats were randomly divided into the three groups; ANP group, thalidomide group and control group with 18 rats in each group. The model of ANP was induced by retrograde injection of 5% sodium taurocholate into the bili-pancreatic duct. Rats in thalidomide group received thalidomide 200 mg/kg body weight gastric lavage 1 h after ANP induction. The rats were sacrificed 3 h, 6 h, and 12 h after ANP induction, and the amount of intraperitoneal ascites was quantified. The serum levels of TNF-α, IL-6, IL-18 were measured by EUSA. The proportion of CD4 + T cell, CD8 + T cell in peripheral blood was determined by flow cytometry. The expression of TNF-α mRNA in pancreatic tissue were measured by RT-PCR. The expression of ICAM-1 protein in pancreatic tissue was measured by immunohistochemistry. Pancreatic tissue underwent pathologic examination. Results Six hours after surgery, the amount of ascite, serum levels of TNF-α, IL-6, IL-18, CD4 + T cell, CD,+ T cell, pancreatic TNF-α mRNA and ICAM-1 protein expression, pathologic score in control group was (1.03 ±0.31)ml,(57.17±11.29)pg/ml, (24.45 ±4.14)pg/ml, (64.23 ±21.85)pg/ml, (47.58 ±9.21)% , (40.88 ± 2.96)%, 0.07 ±0.02, 0.57 ±0.30, 0.67 ±0.81, respectively, and the corresponding values were (3.63 ± 0.38)ml, (107.54 ±33.05) pg/ml, (47.30 ± 11.40) pg/ml, (367.76 ± 108.43 ) pg/ml, (54.90 ± 7.15)%, (17.17 ±3.12)%, 0.65 ±0.26, 3.20 ±0.57, 11.50 ±1.87 in ANP group; and (1.45 ±0.53)ml, (80.60 ±20.48) pg/ml, (26.61 ±10.85) pg/ml, (321.82 ±85.20) pg/ml, (29.80 ±2.19)% , (15.52± 1.96)%, 0.35 ±0.23, 2.37 ±0.67, 8.00 ±3.03. Besides the value of CD8 + T cell was significantly decreased, all other values were significantly increased when compared with control group (P <0.05). Conclusions Thalidomide can decrease the release of inflammatory mediator, and reduce the pathological damage of pancreas of ANP rats by inhibiting TNF-α mRNA expression.

Objective To investigate the effect of melatonin (MT) on the proliferation and apoptosis in human pancreatic cancer cell SW1990 in vitro.Methods SW1990 cell line were treated with MT at different concentrations (0.1,0.5,1.0,2.5 and 5.0 mmol/L) and at different time points (24 h,48 h and 72 h).Cell proliferation was evaluated by MTT and apoptosis was determined by AnnexinV/Pl,cell cycle was determined by flow cytometry,and Western Blot was used to detect the expression of Bcl-2 and Bax.Results MT could inhibit the proliferation of SW1990 cell in a time and dose dependent manner.48 h after 0.1～5.0 mmol/L MT treatment,the proliferation inhibitory rate was 7.4%～85.8%,the proportion of SW1990 cell in phase G0/G1 was 72.6%～85.33%.48 h after 1～5.0 mmol/L MT treatment,the apoptosis rate was 21.5% ～41.7%,and the expression of Bcl-2 was down-regulated and the ratio of Bcl-2/Bax decreased.Conclusions MT could inhibit the proliferation of SW1990 pancreatic cancer cells by up-regulating the expression of Bax and down-regulating the expression of Bcl-2,as well as enhancing apoptosis and blocking SW1990 cell in phase G0/G1.
