Minimally invasive treatment of liver cancer plays a very important role in clinical practice in China, because most patients had the background of hepatitis or cirrhosis and were prone to recurrence after radical resection of the tumor. In the past four decades, much progress has been made in controlling liver cancer, which is well consistent with the trends of minimally invasive treatment. Minimally invasive therapy is also the main goals of our practice and has a great potential developing future, although a good outcome is the prerequisite. Nowadays, minimally invasive treatment for liver cancer includes percutaneous transarterial chemotherapy or embolization (TAE or TACE), percutaneous ethand injection (PEI), and ablation with radiofrequency, micromave, cryosurgery or high intensity focused ultrasound.

Three-dimensional conformal radiation therapy(3DCRT) is a new physical method which can enhance the therapeutic gain factor(TGF) of radiotherapy. It can escalate the doses of local tumor and decrease the doses of normal tissue. For patients with primary liver tumors, 3DCRT can increase the local control rates, prolong patients survival and decrease the incidence of radiation-induced complications.

Objective:To observe the effect of acupoint massage plus acupoint sticking therapy for the stress reaction during postoperative anesthesia recovery period in patients undergoing nasal endoscopic surgery.Methods:A total of 120 patients undergoing nasal endoscopic surgery were included,and all patients were under trachea intubation and general anesthesia.The patients were randomized into an observation group and a control group,with 60 patients in each group.Patients in the control group received conventional anesthesia resuscitation,while patients in the observation group received acupoint massage plus acupoint sticking therapy on the basis of conventional anesthesia resuscitation.Changes in the heart rate (HR),systolic blood pressure (SBP) and diastolic blood pressure (DBP) were observed at three time points including the end of the surgery (TO),the removal of the tracheal tube (T1) and 10 min after the removal of the tracheal tube (T2).The awakening and tube removal time,choking cough and restlessness,and adverse reactions (dizziness,nausea and vomiting) in 24 h post-surgery period were compared.Results:At T1 and T2,the comparisons of HR,SBP and DBP between the two groups showed statistical significance (all P＜0.05).Intra-group comparisons showed that the HR,SBP and DBP of the control group at T1 and T2 were significant different from those at TO (all P＜0.05).There were significant differences in the awakening time and tube removal time between the two groups (both P＜0.05).The incidences of choking cough and restlessness were 8.3％ and 3.3％ respectively in the observation group,versus 53.3％ and 30.0％ in the control group,and the between-group comparisons showed statistical significance (both P＜0.05).The incidences of dizziness,nausea and vomiting in 24 h post-surgery period were 3.3％,5.0％ and 0.0％ respectively in the observation group,versus 43.3％,33.3％ and 25.0％ in the control group,and the between-group comparisons showed statistical significance (all P＜0.05).Conclusion:Acupoint massage plus acupoint sticking therapy can effectively regulate the stress reaction during postoperative anesthesia recovery period in patients undergoing nasal endoscopic surgery,and maintain a stable internal environment.

OBJECTIVE To study the clinical species distribution and drug resistance of Enterococcus.METHODS We had collected 201 isolates of Enterococcus by cultured in normal methods in our hospital from July 2005 to June 2008,and analyzed the characteristics of species distribution,drugsensitive test,drug resistance of high concentration aminoglycoside antibiotics and measured the ?-lactamase.RESULTS There are 106 E.faecalis strains(52.7%),76 E.faecium strains(37.8%) and 19 the other Enterococcus strains(9.5%).There were 102 Enerococcus strains separated from urine and 46 separated from sputamentum.The drug resistance rate of Enterococcus faecalis to erythromycin,tetracycline,rifampin and ciprofloxacin were more than 75.0% and the resistance rate of E.faecium to penicillin,ampicillin,erythromycin,rifampin,ciprofloxacin and nitrofurantoin were more than 93.0%;the total resistance rate of Enterococcus to vancomycin and teicoplanin were 14.4% and 10.4%,respectively.The number of the isolates resistant to high concentration aminoglycoside antibiotics was 151(75.1%);Enterococcus with positive ?-lactamase were 74(36.8%).CONCLUSIONS The infection in urinary system and respiratory system were mainly caused by E.faecalis and E.faeciumwith multidrug resistance.

Objective To determine the effect of the modified UW (University of Wisconsin)solution in the treatment of acute renal tubular necrosis in newborn swine. Methods Ten one-week-old newborn swine were used to establish the animal model of acute renal tubular necrosis by clamping their renal arteries,and were divided into two groups: the model group( n = 5 ) and the treatment group ( n = 5 ) in which fructose diphosphate sodium UW solution was used. Sham surgery was performed on other five swine, which were used as the sham group. At 12 h,l d,2 d,3 d and 7 d after the operation,the urine volume,urine protein,blood urea nitrogen(BUN) and creatinine(Cr) were determined. At 12 h ,24 h and 7 d after the operation ,renal pathological examination was conducted. Results The renal pathological examination and the blood biochemistry tests showed that the animal model was successful. BUN and Cr in the model group and the treatment group were significantly higher than those in the sham group at 12 h after operation(P ＜0. 05) ,and they arrived at their peak values at 2 d after operation,showed remarkable decline at 7 d,especially in treatment group,and returned to the level of the sham group. The urine protein in the model group and treatment group were higher than those in the sham group at various times(P ＜0.05 or P ＜0.01) and it peaked at 1 d after operation,then declining gradually,especially in the treatment group. Compared with the sham group,there were a significant decrease in the urine volume at various times in the model group(P ＜0. 05 or P ＜0. 01 ) ,while in the treatment group,the decrease in the urine volume were significant only at 12 h, 1 d and 2 d( P ＜ 0. 05 ) ,and turned insignificant at 3 d and 7 d. The pathological examination showed that the pathological changes in the treatment group were significantly milder than those in the model group. Conclusion The modified UW solution is effective in reducing the acute renal tubular necrosis in newborn swine.

OBJECTIVETo construct the recombinant plasmid of RCAS1, to express and purify its fusion protein GST-RCAS1, and to investigate its biological function.

METHODSRCAS1 encoding gene was amplified by RT-PCR from total RNA extract of MCF-7 cells and was ligated with expression plasmid vector pGEX-2T by T4 DNA ligase after digested by the restricted endonucleases BamH I and EcoR I. Then the ligated products were inserted into competence JM109 E. Coli and the positive recombinants were identified by restriction endonuclease digestion assay and DNA sequencing. The GST-RCAS1 fusion protein expression was induced by IPTG in BL21 E. Coli and was purified with GST column and identified by SDS-PAGE and Western blotting with anti-GST monoclonal antibody, anti-RCAS1 (N-18) and anti-RCAS1 (C-20) polyclonal antibody. The apoptosis of activated T cells induced by GST-RCAS1 fusion protein was detected by flow cytometry with Annexin V and propidium iodide (PI) staining.

RESULTA 642 bp product was cloned by RT-PCR and the recombinant plasmid was constructed successfully. The GST-RCAS1 fusion protein was recognized by GST monoclonal antibody and RCAS1(N-18 and C-20) polyclonal antibody. FACS analysis showed that GST-RCAS1 fusion protein induced apoptosis in activated T cells.

CONCLUSIONThe recombinant plasmid of RCAS1 has been successfully constructed and the GST-RCAS1 fusion protein expressed and purified. The apoptosis inducing effect of GST-RCAS1 fusion protein on activated T cells is demonstrated.

Objective To explore the application of propofol combined with midazolam intrave-nous anesthesia in pediatric upper gastrointestinal endoscopy, Methods A total of 497 ASA Ⅰ～Ⅱ patients who received sedative upper gastrointestinal endoscopy were assigned to a children group (2～14 years) and an adults group (18～65 years). The 2 groups were treated with midazolam (0.02～0.03 mg/kg, iv) and propofol (0.6～0.7 mg/s, iv) with an interval of 3～5 minutes. Enterseopy was inserted at light sleep, relaxing muscles, and disappearance of eyelash relaxation. Combining of pro-endoscopy, reaction to intravenous administration, dose of propofol, reaction to en-doscopy, time of returning to consciousness, changes of SpO2, R, HR, and BP, and sedative quali-ty were evaluated. Results Good sedation of the 2 groups after intravenous administration was ob-served. Rate of combining of pro-endoscopy in children was lower (42%) than that in adults (100%). The incidence of restlessness, hyperphasia, temporary decreasing of SpO2, dose of propofol of per kilogram weight, time of returning to consciousness in the children were 82.7%, 17%, 2.4 mg/kg, and (17.5±3.2)min, respectively, which were all higher in the adults [9%,4%,1.4 mg/kg, and (9.5±1.3)min, P<0.01]. HR and BP decreased in the 2 groups, and recovered rapidly after the endoscopy. There was no significant difference between the 2 groups (P>0.05). Conclusion It is safe and effective to use propofol combined with midazolam intravenous sedation anesthesia in pediatric upper gastrointestinal endoscopy.
