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.

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.

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 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.

Background and purpose:EGFR-TKI (EGFR-tyrosine kinase inhibitors), represented by geiftinib and erlotinib, have exhibited signiifcant antiproliferative effects against non-small cell lung cancer (NSCLC) with low toxicity.EGFR gene mutation was discovered to be a predictive biomarker for EGFR-TKI treatment. Although the efifcacy of EGFR-TKI is limited toEGFR wild-type patients, it is still noticeable suggesting that some other mechanisms are responsible for it. The current study is aimed at evaluating the expression of phosphorylated EGFR in advanced NSCLC, investigating its relationship withEGFR mutations and EGFR-TKI efifcacy.Methods:EGFR gene mutations were detected by denaturing high performance liquid chromatography (DHPLC) in 205 stageⅢB-ⅣNSCLC patients. The expressions of phosphorylated tyrosine 1068 (pTyr1068) and 1173 (pTyr1173) were detected by immunohistochemistry.Results:The positive expressions of pTyr1068 and pTyr1173 were 80.0% (164/205) and 57.6% (95/165) respectively. None of them were related to clinical pathological characteristics (age, gender, pathological type, smoking status, disease stage).EGFR gene mutation rate was 44.9% (92/205), which was only related to smoking status (P=0.024) compared to other clinical pathological characteristics.EGFR gene mutations were poorly related to pTyr1068 expression (P<0.001) and not related to pTyr1173 expression (P=0.297). The objective response rate (ORR),disease control rate (DCR), and progressive free survival (PFS) of EGFR-TKI treatment in patients withEGFR mutations were 48.3% (43/89), 80.9% (72/89) and 8 months (95%CI: 6.11-11.42) respectively, which were signiifcantly higher than that ofEGFR wild-type patients [ORR=16.2% (17/105,P<0.001); DCR=56.2%(59/105,P<0.001); Median PFS: 2.1 months, (95%CI: 0.89-3.24;P=0.001)]. Superior ORR: DCR and PFS appeared in patients with pTyr1068 positive expression compared to negative [ORR: 37.7% (58/154)vs 5.0% (2/40,P<0.001); DCR: 74.7% (115/154)vs 40.0% (16/40,P<0.001); Median PFS: 7.0 monthsvs 1.2 months,P<0.001)]. Inversely, the patients with pTyr1173 positive expression had lower ORR, DCR and shorter PFS [ORR: 27.8% (25/90)vs 37.9%(25/66,P=0.123); DCR: 64.4% (58/90)vs 83.3% (55/66,P=0.007); Median PFS: 4.8 monthsvs 7.7 months (P=0.016)]. In subgroup ofEGFR wild-type patients, positive expression of pTyr1068 was 69.0% (69/100).EGFR wild-type patients with pTyr1068 positive expression had a prolonged PFS and elevated ORR and DCR compared to negative [median PFS: 3.6 monthsvs 1.2 months (P<0.001); ORR: 23.2%vs 3.2% (P=0.010); DCR: 69.6%vs 35.5% (P=0.001)]. Sixteen patients with pTyr1068 positive expression who responded to EGFR-TKI treatment in this subgroup had a remarkable PFS [median PFS: 15.6 months (95%CI:7.28-23.9)]. Multiple factor analysis showed that the expression of pTyr1068 was an independence predictor factor for EGFR-TKI treatment (OR=0.24, 95%CI: 0.16~0.37,P<0.001). Conclusion:Phosphorylation at Tyr1068 of EGFR might be a potential predictive factor for clinical response and survival of EGFR-TKI treatment in patients with advanced NSCLC, especially inEGFR wild-type patients.

Objective: To evaluate the effect of NGX6 with 5-Fu on the apoptosis of colon cancer cells. Methods: The NGX6-transfected HT-29 cell line with 5-Fu was used in the test group. HT-29 cell line with 5-Fu and PDTC was used in the control group. The expression of NF-κB was detected by EMSA. The proliferation of HT-29 cell line was assayed by MTT. The effect of NGX6 on the apoptosis was detected by FCM. HT-29 cells were double-stained by PI/Annexin-V and AO/EB and observed by fluorescence microscopy. Results: The expression of NF-κB was inhibited in NGX6 transfected colon carcinoma cell group and in colon carcino-ma cell group treated with PDTC. Treatment with the chemopreventive compounds 5-Fu and PDTC resulted in different responses in the effects of anti-proliferation and induced apoptosis of colon carcinoma cells. There was no significant difference in apoptosis between NGX6-transfected HT-29 call line with 5-Fu and the cells in the control group. NGX6 gene enhanced the effect of 5-Fu on the proliferation and apoptosis of colon carcino-ma cells. Conclusion: NGX6 gene can induce apoptosis and inhibit the proliferation of colon carcinoma cells. NGX6 gene can enhance the effect of 5-Fu on the proliferation and apoptosis of colon carcinoma cells through NF-κB pathway.
