Objective To compare the effect and safety of totally transumbilical single -port laparoscopic herniorrhaphy and traditional surgery in treatment with pediatric indirect inguinal hernia.Methods 100 children with indirect inguinal hernia were divided into control group(n =50)and observation group(n =50).The control group was given to traditional surgery.The observation group was given to totally transumbilical single -port laparoscopic herniorrhaphy.The operation related index,postoperative complications and hernia recurrence rate were compared between the two groups.Results The intraoperatve bleeding,incision length,operation time and hospital stays of the observation group respectively were (18.1 ±5.9)mL,(1.3 ±0.3)cm,(27.4 ±7.9)min and (4.5 ±1.2)d,those of the control group respectively were (38.7 ±8.1)mL,(2.2 ±0.4)cm,(46.7 ±9.2)min and (7.4 ±1.3)d,the difference was statistically significant (t =3.439,3.811,2.872,2.878,P =0.026,0.019,0.045,0.049).The postoperative complications rate of observation the group and the control group were respectively 8.0%(4 /50)and 24.0%(12 /50),the difference was statistically significant(χ2 =4.762,P =0.029).Postoperative follow -up of 1 year,the hernia recurrence rate of the observation group and the control group respectively was 0(0 /50)and 12%(6 /50),the difference was statistically significant (χ2 =6.383,P =0.012).Conclusion Using totally transumbili-cal single -port laparoscopic herniorrhaphy treat with pediatric indirect inguinal hernia is safe and effective.It is ben-eficial to prevent recurrence,and is worth clinical promotion.

Purpose:To study the clinical response and the toxic-side reactions of patients with gastric cancer treated with continuous infusion of fluorouracil (5-FU) lasting 240 hours.Methods:35 cases of gastric cancer were treated with continuous infusion of 5-FU lasting 240 hours.32 cases of gastric cancer were treated with traditional infusion of 5-FU on days 1 to 5. The clinical response and the toxic -side reactions were observed.Results:35 cases were treated with continuous infusion of 5-FU regimen with a response rate of 51.4%. 32 cases were treated with traditional infusion of 5-FU regimen with a response rate of 25.0%,thus between them,there was a significant difference in curative effects. The toxicities in traditional infusion of 5-FU group were more severe than in continuous infusion of 5-FU group. They included myelosuppression nausea et al.Conclusions:Continuous infusion of 5-FU regimen is preferable in the treatment of gastric cancer.

Objective As SELDI-TOF-MS (Surface Enhanced Laser Desorption/Ionization Time of Flight Mass Spectrometry) has been broadly used to screen biomarkers for a variety of diseases, the identification and validation of the revealed biomarkers requires more focused attention.Method In this paper, the serum samples from 60 cholangiocarcinoma, 146 lung cancer, 65 LGC and 58 LPC, 49 benign diseases of hepatobiliary and 53 normal individuals were analyzed by SELDI-TOF-MS. Results Among a set of proteins automatically selected as specific biomarkers by Biomarker Wizard software, three protein peaks, with molecular weights of 13. 71 × 103 , 13.83 × 103 and 13. 99 ×103 , were found significantly decreased in cholangiocarcinoma samples. The candidate biomarkers obtained from Tricine-SDS-PAGE gel bands by matching the molecular weight with peaks on CM10 chips were identified by Mass spectrometry as the native transthyretin(native TTR),cysTTR and glutTTR.These preliminary results were further proven by immunoprecipitation using commercial TTR antibodies. This allowed us to re-measure the TTR levels in all the groups more simply by ELISA assay. It showed a firm consistency between ELISA and SELDI analysis. In addition, while TTR levels in cholangiocarcinoma were found to be lower than those in normal healthy controls, TTR levels in benign diseases of the hepatobiliary system were found to be higher than those in healthy controls.Conclusion TTR could be a biomarker that better discriminates cholangiocarcinoma patients from the benign diseases compared to other biomarkers presently available.

Objective To investigate whether HSP90α could be a sensitive and specific serum biomarker for the diagnosis and progression of lung cancer. Methods In the present study, different secretomic analy-ses on the two human lung adenocarcinoma cell lines CL1-0 and CL1-5 with low and high metastatic poten-tial, respectively, were performed using sodium dodecyl sulfate-polyacrylamide gel electrophoresis and ma-trix-assisted laser desorption/ionization time-of-flight mass spectrometry. The candidate biomarker was con-firmed by Western blotting, and was further analyzed in 224 serum samples including 141 lung cancer, 37 benign pulmonary diseases, as well as 46 healthy individuals using ELISA assay. Results HSP90α was sig-nificantly upregulated in the CM of CL1-5 cells. It was found that the levels of HSP90α were specifically ele-vated in the sera of non-small cell lung cancer compared with other groups. At the cut-off point 0.535 on the receiver operating oharacteristie curve, HSP90α could comparatively discriminate lung cancer from benign lung disease and healthy control groups with sensitivity of 0. 817, specificity 0. 919 and total accuracy 80. 14%. Conclusion HSP90α may be a potential useful serum biomarker for discriminating lung cancer from benign lung diseases and healthy individuals and staging of non-small cell lung cancer.

Aim To investigate the effects of harpagide on cerebral ischemia and the mitochondria mediated Caspase dependent apoptotic signaling pathway in mice.Methods The MCAO was employed to establish MCAO model.When the models were established, the mice were given harpagide (4, 8, 12 mg·kg-1) and edaravone (3.2 mg·kg-1) [0.1 ml·(10 g)-1] by tail vein injection after MCAO immediately.And the model and control mice were given equivalent normal saline by the same way.After MCAO for 6 h, the behavior, volume of cerebral ischemia and pathological changes in the brain were observed.Westernblot was employed to determine the contents of Cyt C in mitochondrion and pro-caspase-3 in endochylema.Results Compared with the model group, harpagide (4, 8, 12 mg·kg-1) could significantly decrease the increased nerve functional score, brain index, brain water content and volume of cerebral ischemia induced by cerebral ischemia.Harpagide (4, 8, 12 mg·kg-1) could reduce the contents of Cyt C in mitochondrion and pro-caspase-3 in endochylema.Conclusion Harpagide may have protective effect on the cerebral ischemia injury in mice, which might be related to the inhibition of the cerebral mitochondria mediated Caspase dependent apoptotic signaling pathway.

This study examined the sodium nitroprusside (SNP) toxicity to central nervous system (CNS) in treatment of patients with aortic dissection (AD). The medical records of 191 AD patients who were admitted to Tongji Hospital, China, from Jan. 1998 to Feb. 2009 were retrospectively analyzed. There were 140 cases of hypertension (73.3%) and 13 cases of Marfan syndrome (6.8%) among the 191 AD patients. A total of 157 patients were given SNP treatment. The toxic reactions of CNS occurred in 18 subjects (11.5%). Most of the adverse reactions occurred on the fifth day following SNP injection. SNP infusion rate was significantly higher in patients who developed CNS toxicity. It was suggested that systemic hypertension is the most common predisposing factor for AD. The combination of SNP with a β-receptor blocker is a medical therapy commonly used in patients with AD. Cyanide and thiocyanate toxicity from SNP treatment is always the consequence of prolonged drug infusion or relatively high dose administration.
