Conclusion The serum interleukin-6, 8, 18 levels could reflected occurrence, development, metastasis and curative effect of the lung cancer in a certain extent, so it was importance for diagnosis, treatment and prognosis of lung cancer to combine examination IL-6, 8, 18.

Objective To research the effect of perioperative thermal preservation on hemostatic function in elderly patients with laparoscopic rectal cancer resection.Methods Eighty-six elderly patients with laparoscopic rectal cancer resection with ASA Ⅰ-Ⅱ were randomly divided into control group (43 patients) and test group(43 patients).Control group was given routine operation,test group was given routine operation and thermal preservation.The nose pharynx temperature was monitored and recorded respectively on preanesthesia,30,60,90 min post-anesthesia and after operation.The level of prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time (TT),platelets (PLT),D-dimer(DD),fibrinogen (FBG),yon Willebrand factor (vWF) were detected on preanesthesia,30,60,90 min post-anesthesia and 24,48 h post-operation.Results The temperature in control group on 30,60,90 min pest-anesthesia and after operation [(36.1 ± 0.2),(36.0 + 0.1),(35.7 + 0.1),(35.6 ± 0.2) ℃] was significantly lower than that on preanesthesia [(36.8 ± 0.2) ℃] and the same time in test group [(36.8 ± 0.0),(36.7 ± 0.1),(36.7 +0.2),(36.8 ±0.2) ℃] (P ＜0.05).The level of PT,APTT and TT in control group on 30,60,90 min post-anesthesia and after operation were significantly longer than those on preanesthesia and the same time in test group (P ＜0.05).The level of PLT in control group after operation and on 24,48 h post-operation were significantly lower than preanesthesia and the same time in test group(P ＜ 0.05).The level of DD and vWF in control group on 24,48 h post-operation were significantly higher than preanesthesia and the same time in test group (P ＜ 0.05).The level of FBG in control group on 24,48 h post-operation were significantly lower than preanesthesia and the same time in test group (P ＜ 0.05).The hemostatic function had no significant change in test group (P ＞0.05).Conclusion The perioperative thermal preservation in elderly patients with laparoscopic rectal cancer resection can alleviate hemostatic function suppression and promote recovery.

Objective To study donor liver repair in modified piggyback liver transplantation and its ~relationship to postoperative complications. Methods The relationship between donor liver repair and ~development of complications of 14 cases of modified piggyback liver transplantation,which among 17 cases of orthotopic piggyback liver allotransplantation performed in our hospital,were analyzed retrospectively.In the 14 cases,abnormal hepatic artery was repaired in 2 cases,portal vein interposition shunt was done in 1 case;~repaired ligaments were sutured in 10 of 14 cases,and not sutured in 4 cases.Results None of the 14 ~patients died in the perioperative period. The success rate of the operation was 100%. 3 patients had ~intra-abdominal bleeding,postoperatively,and in 2 cases the bleeding was related to donor liver repair. ~Postoperatively ,there was no thrombosis of hepatic artery or portal vein, and no bile duct necrosis, no hepatic outflow tract occlusion. Conclusions Donor liver repair is an important procedure in liver tramsplantation.The quality of donor liver repair is directly related to the difficulty of operative technique during liver ~transplantation ,and to the development of postoperative complications.In donor liver repair during piggyback liver transplantation,reconstruction of the retrohepatic vera cava is very important.The constructed stoma must be compatible with the donor hepatic vein outflow stoma and be able to effectively prevent the formation of eddy blood flow,ensure patency of the outflow tract and effectively prevent thrombus formation.

Objective To explore the feasibility and clinical value of the trans-umbilical single-port laparoscopic operation with routine apparatus in treatment of hepatobiliary diseases. Methods From Mar 2010 to Sep 2012, 415 patients with hepatobiliary disease, splenic disease, abdominal cavity disease or combine hysteromyoma were performed by trans-umbilical single-port laparoscopic operation with routine apparatus. The clinical data of 415 cases were analyzed respectively.Result All patients except one patients who was added one port for hysterectomy, were performed successfully trans-umbilical single-port laparoscopic operation with routine apparatus without conversion to laparotomy or conventional laparoscopic surgery. Conclusions The trans-umbilical single-port laparoscopic operation with routine apparatus is safe and effective in treatment of hepatobiliary diseases. Limited by the anatomy position, the trans-umbilical single-port laparoscopic operation with routine apparatus can cure most hepatobiliary diseases. So the operator must have the experience both in single-port laparoscopic operation and traditional laparoscopic operation. With the improvement of rotatable equipment, the practical procedure is expected to be generalized in the future.

Objective:To investigate the efficacy and toxicity of oxaliplatin reintroduction combined with raltitrexed as second-line che-motherapy after the first-line oxaliplatin-based chemotherapy in advanced colorectal cancer patients. Methods:The 48 evaluable pa-tients with advanced colorectal cancer following disease progression prior to the first-line chemotherapy were treated with oxaliplatin and raltitrexed (raltitrexed 3 mg/m2 ivgtt d1, oxaliplatin 100-130 mg/m2 ivgtt d1, q21d). All 48 patients were divided into two groups:Group A, non-oxaliplatin-based regimens as the first-line chemotherapy, 20 cases;Group B, oxaliplatin-based regimens as the first-line chemotherapy, 28 cases. Each group was evaluated every two cycles. Results:The response rates (RR) of Groups A and B were 30.0%(6/20) and 32.1%(9/28), the disease control rates (DCR) were 80.0%(16/20) and 75.0%(21/28), the median progression free survival time (mPFS) was 6.5 and 7.0 months, and the median overall survival time (mOS) was 10 and 13 months, respectively. No statistical sig-nificance was observed between the two groups in their RR, CR, mPFS, and mOS (P=0.264, 0.514, 0.713, 0.788), respectively. The most common adverse effects observed wereⅠ-Ⅱgrades of bone marrow suppression, aminotransferase abnormality, and digestive toxici-ties. The incidence of neurotoxicity (Ⅰ-Ⅱgrades) between the two groups was similar. Conclusion:Instead of irinotecan combined with raltitrexed, oxaliplatin reintroduction combined with raltitrexed for second-line chemotherapy after the first-line oxaliplatin-based chemotherapy in advanced colorectal cancer patients is feasible.

Objective To investigate the differences in the safety of the operation of different hepatic vascular exclusion for liver surgery. Methods Sixty patients with liver resection were grouped by different hepatic blood flow blocking methods, and given pre-operative assessment prior to surgery. Results On the first day after surgery, the average levels of ALT and AST were (395.0 ± 220.2) U/L and (415.3±311.0) U/L in patients who received Pringle’s method (110.2±53.0) U/L and (125.6±78.5) U/L in patients who received regional hepatic vascular exclusion, (98.9±32.2) U/L and (96.2 ±66.5) U/L in patients who didn't receive hepatic vascular exclusion, respectively. Postoperative liver function damage was more serious in patients who received Pringle's method than patients who received regional hepatic vascular exclusion or patients who didn't receive hepatic vascular exclusion, the difference was statistically significant (P<0.05) .Conclusion Regional hepatic vascular exclusion or not can not only reduce the incidence of postoperative complications, but also expand the indications for liver resection.

Objective To study the significance of human rhinovirus C as a pathogen and the clini-cal features of human rhinovirus C infection in pediatric intensive care unit. Methods From November 2010 to April 2012,570 nasopharyngeal aspirates specimens were collected from children who were admitted to the pediatric intensive care unit with respiratory infections. Nest reverse transcription-polymerase chain reactions were applied to detect the human rhinovirus C. The other common respiratory viruses were detected by multi-plex polymerase chain reaction. The clinical data were collected. Results One hundred and seventy human rhinovirus positive samples ( 29. 8%) were detected in 570 nasopharyngeal aspirates specimens. The VP2/VP4 and 5′UTR region of the human rhinovirus genome was amplified from 170 human rhinovirus positive samples with 80. 6%(136/170) success. While 20. 0%(34/170) samples in total were unclassified to spe-cies. There were 85 single infected samples including 52 of type A,7 of type B,26 of type C. The nucleotide homology was 74. 0% to 99. 2% and the nucleotide variations was 3. 4% to 32. 3% in stains of human rhino-virus C. The late fall and early winter were the epidemic seasons of human rhinovirus C infection. Cough,fe-ver, polypnea and wheezing were the common symptoms. Conclusion Human rhinovirus C is the major cause of infectious disease in pediatric critical illnesses. Human rhinovirus C infections often cause cough, fever,polypnea and wheezing.
