Objective To observe the long?term survival and adverse reactions in patients with stage T4 N (+) Ⅲ middle and lower thoracic esophageal carcinoma undergoing intensity?modulated radiotherapy ( IMRT) . Methods From 2004 to 2010, 300 patients with stage T4 N (+) Ⅲ middle and lower thoracic esophageal carcinoma, consisting of 202 treated with three?dimensional conformal radiotherapy ( 3DCRT ) and 98 treated with IMRT, were enrolled as subjects. All patients received conventionally fractionated radiotherapy with a prescribed dose of 60 Gy. The long?term survival and adverse reactions were compared between patients treated with the two different radiotherapy regimens. The survival rates were calculated by the Kaplan?Meier method and analyzed by the log?rank test. Results The 5?and 7?year sample sizes were 239 and 120, respectively. The 3DCRT group had significantly lower 1?, 3?, 5?, and 7?year local control (LC) and overall survival (OS) rates than the IMRT group (64. 4% vs. 68. 3%, 40. 6% vs. 55. 3%, 38. 3% vs. 51. 9%, 34. 2% vs. 51. 9%, P=0. 048;54. 5% vs. 63. 3%, 19. 8% vs. 34. 7%, 14. 7% vs. 24. 4%, 10. 9% vs. 20. 3%, P=0. 013) . The stratified analysis showed that for patients older than 65 years, with the length of esophageal lesion>8. 0 cm before radiotherapy, the largest diameter of esophageal lesion in computed tomography image>4. 6 cm, gross tumor volume ( GTV)>60 cm3 , metastases to adjacent tissues or organs, stage N2 , and without chemotherapy, the IMRT group had a significantly higher OS rate than the 3DCRT group (P=0. 022,0. 003,0. 022,0. 034,0. 016,0. 044,0. 047). The GTV Dmin and GTVD100 were significantly higher in the IMRT group than in the 3DCRT group ( P=0. 000,0. 000) , while the Dmax of the spinal cord was significantly lower in the IMRT group than in the 3DCRT group ( P=0. 000) . Compared with the 3DCRT group, the IMRT group had a significantly higher incidence of acute radiation?induced esophagitis, particularly grade 1?2 esophagitis (P=0. 000). The mortality rate caused by local tumor was significantly higher in the 3DCRT group than in the IMRT group ( P= 0. 039 ) . Conclusions In the treatment of locally advanced middle and lower thoracic esophageal carcinoma, IMRT is safe and effective;it significantly improves the LC rate and long?term survival without severe toxicity to normal tissues. The results of this retrospective study need to be confirmed by prospective randomized controlled studies.

Objective To investigate the effects of dosimetric differences in gross tumor volume ( GTV ) on local control and survival rates in patients with esophageal carcinoma undergoing three?dimensional ( 3D) radiotherapy,and to provide a basis for clinical treatment. Methods From January 2004 to December 2010, 548 patients with esophageal carcinoma received conventional fractionated 3D radiotherapy with a prescribed dose of 60 Gy. All patients were divided into low?dose group and high?dose group according to the dosimetric differences in GTV. The survival and local control rates were compared between the two groups. The survival rates were calculated using the Kaplan?Meier method and analyzed using the logrank test. The Cox regression model was used for the multivariate prognostic analysis. Results The number of sample were 456 and 216 patients at 5 and 7 years followed time. The 1?,3?,5?,and 7?year local control rates were significantly higher in the high?dose group than in the low?dose group ( 83?5% vs. 71?3%, 62?6% vs. 44?8%,57?5% vs. 41?7%,52?9% vs. 38?8%,P=0?000).The 1?,3?,5?,and 7?year survival rates were also significantly higher in the high?dose group than in the low?dose group ( 79?6% vs. 66?3%, 44?3% vs. 29?7%, 34?0% vs. 21?8%, 26?1% vs. 17?0%, P=0?000 ) . The univariate prognostic analysis using the Cox regression model showed that Dmin , Dmean , and D100 for GTV were prognostic factors ( P=0?000,0?001,0?000).In all the 548 patients,201 were assigned to the high?dose group and the others to the low?dose group. Compared with the high?dose group, the low?dose group showed significantly larger GTV (38?2 vs. 48?1 cm3,P=0?002) and more advanced T stages (P=0?035).The stratified analysis showed that the 1?,3?,5?,and 7?year local control and survival rates were significantly higher in the high?dose group than in the low?dose group,regardless of tumor location,GTV,TNM stage,or chemotherapy. The multivariate analysis using the Cox regression model indicated that tumor location and grouping based on the radiation dose to GTV were independent prognostic factors. Conclusions In 3D radiotherapy for treating esophageal carcinoma,a high?quality treatment plan and GTV dose assurance improve the survival rates in patients. The patients with lower Dmin ,Dmean ,and D100 for GTV than the prescribed dose have a poor prognosis.

Objective To investigate the parameters of diffusion?weighted magnetic resonance imaging ( DWMRI) for prediction of the efficacy of chemoradiotherapy ( CRT) for esophageal squamous cell carcinoma ( ESCC) , to determine the optimal time point and threshold for prediction, and to provide a basis for clinical practice. Methods From 2010 to 2011, 38 patients with ESCC were consecutively enrolled as subjects. All patients received three?dimensional conformal radiotherapy with 60 Gy in 30 fractions for 6 weeks. They also received concurrent or consolidation chemotherapy ( FP or TP scheme ) as adjuvant treatment. Patients received DWMRI scans before radiotherapy and at weeks 1?6 during radiotherapy. The apparent diffusion coefficient ( ADC ) values and tumor lengths obtained from serial DWMRI scans were recorded and analyzed. Comparison was made by paired t test. Repeated measurements were analyzed by analysis of variance ( ANOVA) and multivariate ANOVA. The prognosis was predicted by the Logistic model. The effectiveness analysis and threshold screening were performed using the receiver operating characteristic (ROC) curve. Results In all patients, 20(52?6%) had complete response (CR) and 18(47?4%) had partial response ( PR) . There were no significant differences in the ADC values before radiotherapy and at weeks 1?6 during radiotherapy between patients with CR and PR ( 1?82 vs. 1?42;1?92 vs. 1?49;2?06 vs. 1?67;2?35 vs. 1?79;2?62 vs. 2?11;2?71 vs. 2?18;2?96 vs. 2?28×10-3 mm2/s;P=0?006,0?003,0?012, 0?001,0?003,0?008,0?002) . The ADC value at third week during radiotherapy was the only independent prognostic factor for short?term treatment outcomes in patients with ESCC ( OR=0?134, P=0?007) . These results were also supported by the multivariate ANOVA analyses. The analysis of the ROC curve showed that at the third week during radiotherapy, the area under the ADC curve was the largest ( A z=0?857) and the diagnostic effectiveness was the best;the threshold value, sensitivity, and specificity were 2?02×10-3 mm2/s, 80?0%, and 92?9%, respectively. Eight patients who had tumor out of control or recurrence within 1 year after treatment had the ADC curve fall down at the end of the fifth week and the reduction of tumor length substantially slow down from the fifth week. Conclusions DWMRI is an effective imaging approach for monitoring tumor response to CRT in patients with ESCC. The ADC value at the end of the third week during radiotherapy may be the optimal time point for prediction of treatment outcomes. The reduction in the ADC value or non?reduction in tumor length at the end of the treatment indicates a high risk of recurrence.

Objective To analyze composition principles of prescriptions for the treatment of diarrhoea caused by deficiency of spleen. Methods The prescriptions for diarrhoea caused by deficiency of spleen in the Prescriptions of Traditional Chinese Medicine Dictionary were collected, sorted and entered into the TCM Inheritance Support System (V1.3) to analyze the composition principles through the methods of entropy clustering and apriori. Results Based on the analysis of 1185 prescriptions and 815 medications, there were 33 medications with more than 50 frequencies. Composition principles were obtained through apriori method:50 herbal pairs were used with more than 50 frequencies, and 29 core combinations with more than 40 frequencies. Association principle rule were used for the analysis of those medications in the prescriptions (support≥20%, confidence≥0.9). Principles were obtained through entropy clustering:there were 19 core combinations which composed the new prescriptions, and 19 new prescriptions were found through hierarchical clustering method. There were 17 prescriptions matching with Sijunzi decoction (semblance=0.5). Conclusion Diarrhoea caused by deficiency of spleen should be treated with strengthening spleen and benefiting qi primarily, assisting with warming yang, excreting dampness and checking diarrhoea.

Objective:To explore the effects and mechanisms of bortezomib on the proliferation and apoptosis of acute T lymphocyte leukemia cell line Jurkat.Methods:MTT assay was used to test the influence of bortezomib on the proliferation of Jurkat cells.Flow cytometry was used to detect the influence of bortezomib on apoptosis of Jurkat cells.Real-time quantitative polymerase reaction(RT-PCR) was used to detect the effects of bortezomib on the expression of Bax, Bcl-2 and Cox-2 genes in Jurkat cells.Results:The inhibition rates of 5ng/mL, 10ng/mL, 20ng/mL and 40ng/mL bortezomib on Jurkat cells at 24h were (13.23±0.71)%, (39.53±0.95)%, (53.07±1.12)%, (60.43±0.75)%, respectively, and the inhibition rates at 48h were (25.20±0.96)%, (52.80±1.30)%, (60.67±0.64)%, (75.10±1.35)%, respectively.The inhibitory rates of proliferation of Jurkat cells at 72h were (38.37±0.93)%, (60.94±0.85)%, (73.83±5.08)%, (88.37±1.55)%, respectively.The inhibitory rates of proliferation of Jurkat cells increased with the increase of drug concentration and the prolongation of action time, and the differences were statistically significant( F=1 602.202, 1 085.089, 181.034, all P<0.05). Bortezomib (5ng/mL, 10ng/mL, 20ng/mL and 40ng/mL) treatment for 24h, 48h and 72h, the apoptosis rate of Jurkat cells increased with the increase of drug concentration and the prolongation of action time, the differences were statistically significant( F=1 288.571, 223.378, 251.175, all P<0.05). The expression of Bax mRNA in Jurkat cells increased with the increase of drug concentration and time( F=258.446, 518.929, 276.764, all P<0.05). The Bcl-2 mRNA and Cox-2 mRNA expression levels decreased with the increase of drug concentration and the prolongation of action time( FBcl-2 mRNA=236.848, 264.849, 343.968, FCox-2 mRNA=679.404, 1288.681, 1541.850, all P<0.05). Conclusion:Bortezomib can inhibit the proliferation and induce apoptosis of Jurkat cells.Bortezomib can increase the expression of Bax mRNA and decrease the expression of Bcl-2 and Cox-2 mRNA, which may be the molecular mechanism of bortezomib to promote apoptosis.

Objective To examine the prediction value of diffusion-weighted magnetic resonance imaging (DWI) on radiotherapy response in esophageal cancer.Methods A total of 24 subcutaneous esophageal cancer xenograft models were randomly divided into experimental group (n =14,received a single dose of 15 Gy radiotherapy) and control group (n =10,without any treatment).MRI were required before and after radiotherapy at different check time points (1,6,13 days) of T1WI,T2WI,and DWI measurements.Apparent diffusion coefficient (ADCX) and volume (VX) of each xenograft were measured,and both △ADCX and △VX were calculated.Results The ADC values of both group were decreased at the first day,however,the decrease in experimental group were more obviously with an increase at 6 and 13 d gradually.However,the ADC values of the control group showed a persistent decline.There was no significant difference in the ADC values between the two different groups before radiotherapy (P ＞ 0.05),while significant difference was found in the ADC values (F =6.178,16.181,58.733,P ＜ 0.05) and △ADC after radiotherapy (F =9.038,12.360,35.140,P ＜ 0.05).The xenografts volume in the experimental group showed a significant growth delay.There was no significant difference in volume between the two groups (P ＞ 0.05) before radiotherapy.Significant difference in V between the two groups only began to exist at 5 d after radiotherapy (F =28.587,P ＜ 0.05).The ADC0,ADC1 of transplanted tumor in control group had linear correlation relationships with its volume of later period.After radiotherapy,the trend of r values gradually increased from-0.118 to 0.896.Conclusions ADC values may change significantly at the early stage after radiotherapy,and initial and early ADC value may have close relationship with xenograft volumes of later period,which indicates that DWI has huge potential in the prediction of radiotherapy response.

Objective:To evaluate the effect of stroke volume variation (SVV)-guided fluid therapy on perioperative haemodynamics and tissue perfusion in the patients with end-stage renal disease (ESRD) undergoing parathyroidectomy.Methods:One hundred and twenty-one patients of either sex, aged 18-64 yr, of American Society of Anesthesiologists Physical Status classification Ⅲ, with body mass index of 18-28 kg/m 2, with ESRD undergoing elective parathyroidectomy, who received haemodialysis treatment within 24 h before surgery, were enrolled in this study. The patients were divided into standard restrictive fluid therapy group (group SRT, n=61) and goal-directed fluid therapy group (group GDT, n=60) using a random number table method. Group SRT received restrictive fluid therapy, with a continuous infusion of 0.9% normal saline at a rate of 4 ml·kg -1·h -1. Group GDT received goal-directed fluid therapy guided by SVV, and when the SVV≥10% lasted for 5 min, the 0.9% normal saline 3 ml/kg was infused within 5 min until SVV<10%. Systolic blood pressure (SBP) was maintained at ≥90 mmHg or mean arterial pressure(MAP) at ≥65 mmHg throughout the perioperative period in both groups. The intraoperative volume of fluid infused, usage rate and consumption of intraoperative vasoactive drugs were recorded, and arterial blood lactate (Lac) level, MAP, heart rate, cardiac output, and inferior vena cava collapse index (IVC-CI) after removal of endotracheal tube at the end of surgery were measured. MAP was continuously recorded within 12 h after surgery, and MAP variability (CV MAP) was calculated. The occurrence of cardiovascular and cerebrovascular events within 30 days after operation was also recorded. Results:Compared with group SRT, the intraoperative volume of fluid infused was significantly increased, the usage rate of ephedrine and norepinephrine was decreased, the consumption of ephedrine was reduced, and the percentage of postoperative IVC-CI<50% and cardiac output were increased, the percentage of Lac≥2.0 mmol/L and CV MAP were decreased ( P<0.05), and no significant change was found in the incidence of cardiovascular and cerebrovascular events within 30 days after surgery in group GDT ( P>0.05). Conclusions:Compared with restrictive fluid therapy, SVV-guided fluid therapy can optimize the perioperative hemodynamics and tissue perfusion in the patients with ESRD undergoing parathyroidectomy.

OBJECTIVETo study the high risk factors of the third level of lymphatic metastasis in breast cancer patients to guide clinical practice.

METHODSThe clinical data of 746 breast cancer patients (all female, aged from 33 to 80 years with a median of 46 years) received radical or modified mastectomy between 2001 and 2011 was analyzed retrospectively. Eleven individual variables were selected to investigate high risk factors of the third level of lymphatic metastasis in different conditions.

RESULTSAxillary nodes metastasis status (OR = 4.541, 95%CI:3.569-5.776), tumor site (OR = 1.437, 95%CI:1.029-2.007), external nodes involved (OR = 3.809, 95%CI:1.683-8.618) and estrogen receptor (OR = 0.740, 95%CI:0.569-0.964) were high risk factors of the third level of lymphatic metastasis. Further analysis found that it is prone to happen a metastasis, especially when the tumor with a size over 5 cm and located at the lateral quadrant. Negative estrogen receptor was a risk factor of the third level lymphatic metastasis along with the tumor stage.

CONCLUSIONFor preoperative tumor biopsy shows Negative estrogen receptor of tumor stage T3 and over stage T3 when considering suspicious lymph node metastasis or external tissues metastasis intraoperatively should take in account into third level axillary lymph node dissection actively.
