Objective To evaluate the efficacy,local control rate,survival rate and adverse reaction of intensity modulated radiation therapy (IMRT) combind with Tp concurrent chemoradiotherapy (docetaxel and cisphtin) for superior segment of esophageal cancer.Methods Seventy-eight patients with superior segment of esophageal cancer were divided randomly into IMRT combined with TP concurrent chemoradiotherapy group (chemoradiotherapy group) and single IMRT group (radiotherapy group) by double blind method with 39 cases each.The patients in chemoradiotherapy group received chemoradiotherapy,while other patients in radiotherapy group received only radiotherapy.For both groups,the same radiation technic was given with chemoradiotherapy,the total dose was 6 400 cGy/32 f.For the patients in chemoradiotherapy group were also given with TP concurrent chemotherapy weekly.The efficacy,local control rate,survival rate and adverse reaction was observed.Results Complete remission in 17 cases,partial remission in 20 cases,stable in 2 cases,the total effective rate was 94.9％ (37/39) in chemoradiotherapy group.Complete remission in 9 cases,partial remission in 19 cases,stable in 11 cases,the total effective rate was 71.8％ (28/39) in radiotherapy group.There was significant difference in the total effective rate between two groups(P ＜ 0.05).The 3-year local control rate was 69.2％ (27/39) in chemoradiotherapy group,which was higher than that in radiotherapy group[35.9％(14/39)],and there was significant difference(P ＜ 0.05).The 3-year survival rate was 74.4％(29/39) in chemoradiotherapy group,which was higher than that in radiotherapy group [43.6％(17/39)],and there was significant difference (P ＜0.05).Conclusion IMRT combined with TP concurrent chemoradiotherapy can improve the efficacy,local control me,survival rate of esophageal cancer,but can also increase the acute toxic effect.

Objective To investigate the changes of gut barrier function under glucocorticoid, so as to understand the reasons of gut-derived infection and bacteria infection.Methods Fifty-six Wistar rats were divided into control and methylprednisolone (Mep, 100 mg/kg, i.p., once every day) groups, and there were four time points in each group (0, 3, 5, 7 day). At each time point the rats were subjected to general anaesthesia and blood, mesenteric lymph nodes, enteric content and ileal tissue were obtained for determination of serum D-lactic, DAO, intestinal microecosystem, apoptosis index of mesenteric lymph nodes and bacterial culture. Results At the latter three time points, compared with control group, serum D-lactic and DAO, and apoptosis index of mesenteric lymph nodes in MeP group were significantly increased (P 0.05) from the day 3 after administration,the positive rate of organs bacterial culture in MeP groups at the No7 day is much higher than that in control group(P

Objective To explore the factors affecting the collection of allogenic peripheral blood stem cells in donors. Methods Using COBE-spectra blood cell separator to collect peripheral blood stem cells in 21 allogenic donors. The impact of the factors including the number of white blood cell(WBC) and nucleated cell(NC), and mono-nucleated cell(MNC) ratio on the collecting rate of peripheral blood stem cells was analyzed before and after collection. The output of CD 34 +stem cells stimulated by different doses of G-CSF was also analyzed. Results When the mean count of peripheral WBC and MMC in donors was (41?7.7)?10 9/L and 12?2.9% respectively, the count of collected NC was 2.7?0.8?10 8/L, and the number of the collected CD 34 + stem cells was also higher. Statistical analysis showed that the number of NC was significantly related to the collecting rate of CD 34 stem cells(P

To preliminarily determine the appropriate dosage of carboplatin (CBP) at AUC of 5 mg.Ml(-1).min(-1) in the combination chemotherapy for Chinese senile patients with non-small cell lung cancer (NSCLC). Thirty-five Chinese senile patients with NSCLC in advanced stage (III/IV) were given 96 cycles of combination chemotherapy. Chemotherapy schedules included Taxol+CBP, Gemzar+CBP and NVB+CBP. The dose of CBP was at 5 mg.mL(-1).min(-1) of area under the concentration-time curve (AUC). Side effects and quality of life were observed before and after the chemotherapy. Myelosuppression was severe and commonly observed. Grade 3/4 of granulocytopenia was found in 47.9% (46/96) of the patients and grade 3/4 of thrombocytopenia was noted in 28.1% (27/96) of the subjects. However, other side effects were slight. The mean score of quality of life (QOL), according to the criteria of QOL for Chinese cancer patients had reduced 6.8. At 5 mg.mL(-1).min(-1) by AUC, the hematological toxicity of CBP was severe and it had some negative effects on the QOL. The administration of CBP at 5 mg.mL(-1).min(-1) by AUC may be too high for Chinese senile patients with non-small cell lung cancer.

Objective Radical surgery is extensively used in the treatment of lung cancer in elderly patients .This study aimed to investigate the effects of acute hypervolemic hemodilution (AHVHD) on the cognitive function and plasma S100βof elderly people following radical surgery for lung cancer . Methods A total of 112 lung cancer patients treated by radical surgery were equally randomized to an AHVHD and a non-AHVHD control group .Using the Mini-Mental State Examination scale ( MMSE) , we evaluated the cognitive function of the patients .We made comparisons between the two groups in the cerebral oxygen metabolism indexes and plasma S100βlevels at T0(immediately after anesthesia induction), T1(15 min after hemodilution), T2(60 min after hemodilution), T3(60 min before the end of surgery ) and T4 ( at the end of surgery ) as well as MMSE scores before and after operation . Results At T1 , T2, T3, and T4, the values of jugular venous oxygen saturation in the AHVHD group were (75.1 ±4.3), (78.5 ±3.1), (79.1 ± 4.4), and (79.6 ±2.8) %, respectively, with time-dependent decreases in Da-jvO2 and cerebral oxygen extraction , and significantly higher than that at T0 (P<0.05) and those in the control group ([63.4 ±2.0], [63.9 ±1.8], [64.2 ±3.0], and [64.7 ±3.2]%) (P<0.05).The levels of plasma S100βat T1, T2, T3, and T4 were remarkably lower in the AHVHD group ([0.53 ±0.04], [0.52 ±0.07], [0.51 ±0.06], and [0.50 ±0.08] μg/L) than in the control ([0.64 ±0.06], [0.64 ±0.04], [0.65 ±0.05], and [0.67 ±0.06] μg/L), with statistically significant differences between the two groups at the same time point (P<0.05).At 1, 3, 5, and 7 days after surgery, the MMSE scores were markedly higher in the AHVHD group (24.3 ±1.7, 26.5 ±1.9, 27.8 ±1.3, and 28.1 ±1.0) than in the control (21.1 ±1.6, 24.0 ±2.1, 25.9 ±1.8, and 26.4 ±1.7) (P<0.05). Conclusion AHVHD can significantly improve cognitive function and reduce plasma S 100βin elderly patients following radical surgery for lung cancer , which may be related to cerebral oxygen metabolism .

Objective To evaluate the effects of two fluid therapy methods guided by SVV and CVP re-spectively on intestinal barrier of colon cancer surgery with elderly patients. Methods 50 elderly patients with ASA Ⅱ~Ⅲ level were randomly divided into Group S (fluid therapy guided by SVV) and Group C (convention-al fluid therapy). Each group has 25 cases. Patients in group S were treated under goal-directed fluid infusion strategy with target of 10%≤SVV≤12%. Group C received conventional infusion characterized by monitoring central venous pressure (CVP) and mean arterial pressure (MAP). Fluid volume, surgery time, urine volume, blood loss, exhausting time, post-operative hospitalization days in Group S and Group C were recorded. MAP, HR, CVP, SVV, HCO3- of patients were recorded at the same time before anesthesia (T0), beginning of surgery (T1), one hour after surgery (T2) and ending of surgery (T3) respectively. Venous blood samples were collected at the time points of T0, T1, T2 and T3 to detect DAO and D-lactic acid levels. Results MAP and CVP at time points of T2 and T3 in Group S were obviously lower than that in Group C; total intraoperative fluid volume in Group S was obviously less than that in Group C (P < 0. 05); postoperative exhausting time and hospitalization days in Group S decreased significantly (P < 0.05) and the content of DAO and D-lactic acid in Group S were lower than that in Group C (P < 0.05). Conclusion For elderly patients with colon cancer surgery, fluid thera-py guided by SVV is better than conventional fluid therapy guided by CVP in protecting intestinal barrier.
