Objective To evaluate the effects of intrarectal chemotherapy for advanced unresectable rectal carcinoma.Methods 86 cases of advanced unresectable rectal carcinoma were divided into two groups. The intrarectal chemotherapy group consisted of 43 cases to whom 5 fluorouracil or fluorouracil polyphase liposome oral liquid were administered by rectoclysis, and extract of Chinese herbs was administered as a adjuvant simultaneously. In the control group there were 43 cases who received oral administration of tegafuri(FT 207) or Fluorouracil polyphase liposome and adjuvant Chinese herbs.[WT5”HZ]Results [WT5”BZ] In the intrarectal chemotherapy group mean survial time was 18 2 months, 8 4 months longer than that in the control group ( SD =0 67, t =12 54, P

Objective To study lymphocyte subsets changes in patients with malignant tumors during chemoimmunotherapy and the clinical significance. Metheds Fifty one cases were treated with chemotherapy and twenty six cases with chemoimmunotherapy. Lymphocyte subsets were determined by flow cytometry. Results Chemotherapy significantly decreased CD 3 +, CD 4 + and NK cells ( P 0 05). Chemoimmunotherapy elevated CD 8 + and NK cells ( P

0 05).buprenorphine buccal produced less nausea and vomiting than those in the other route(P0 05).The changes of the vital signs in two groups were not clinically important. Conclusions The study indicates that the analgesia effects of buprenorphine sublingual administered is same as intramuscular buprenorphine,but the buprenorphine buccal is more convenient.However,the drug dependence terdency should be monitored.

Objective To investigate three-dimensional localization for sentinel lymph node (SLN) of breast cancer,and by which we can remove the SLNs directly.Methods The ipsilateral axillary lymph nodes of 40 patients were inspected by B-ultrasound and axillary artery and subscapular artery bifurcation point and its trend with Doppler B-ultrasound in the preoperation,then located them in the surface.We found SLNs using methylene blue as the mapping agent with endoscope during the operation,determined which lymphatic group the sentinel lymph node belonged and the spatial location and the surface projection according to the anatomical location.Results We found the three-dimensional location of SLNs in the group of 39 in 40 patients with endoscope,of which 34 cases located in central group,accounting for 87.18％ ;while 4 cases located in the subscapular group,accounting for 10.26％,and their spatial location was as follows:set the root of subscapular artery in this location as a starting point,the subscapular artery as a diameter,and made a diameter of 5cm circle to the bottom,then let the latissimus dorsi as the end,and made a quasi-cylinder through the circle to the axillary central.The height of the quasi-cylinder got up to the surface of the intercostal brachial nerve.Then set the nerve as the diameter of circle of quasi-cylinder,and the centre of circle was crosspoint of subscapnlar artery's surface projection with intercostal brachial nerve.The height of quasi-cylinder varies with somatotypes of the patients,its height was less than or equal to 5cm.What's more,the fiften enlarged lymph nodes located by B-ultrasound in the preoperation were all in the quasi-cylinder,and they were SLNs.Conclusion SLN lies in quasi-cylinder consisting of spatial location of subscapular group and central group lymph nodes.If the enlarged lymph nodes found by B-ultrasound are in above mentioned quasi-cylinder,they can be considered as the SLNs.Make a 5cm-incision parallelling the intercostal brachial nerve and intersecting the surface projection of subscapular artery in the surface of quasi-cylinder,then dissect toward the origin of the subscapular artery,you can find SLNs.

Objective To investigate the clinical values of laparoscopic radiofrequency ablation in liver cancer and its impacts on serumal VEGF and MMP-2. Method From Jan, 2012 to Dec, 2013, a series of patients with primary liver cancer were studied, patients were randomly signed into LAFA group or control group. During the study period, LRFA group were treated with laparoscopic radiofrequency ablation combined with FOLFOX4 chemotherapy while patients in control group were treated with PIAF chemotherapy only. The primary outcomes were the Health related quality of life score (HRQL), the degree of solid tumors classification, progression-free survival duration and 2-year mortality. The secondly primary outcomes included the level of serumal VEGF and MMP-2. Result When compared with the control group, patients in LRFA group got a significantly lower rate of disease progression (28.33 % vs 50.00 %, P = 0.015); a longer progression-free survival duration (500 vs 380 d, P = 0.013); a higher HRQL (80.33 ± 5.84 vs 65.87 ± 9.59, P = 0.000); a significantly lower level of VEGF at 7 days, 14 days, 28 days and 6 months after the clinical intervention were started (all P values were 0.000); a significantly lower level of MMP-2 at 14 days, 28 days and 6 months after the clinical intervention were started (the P values were 0.003, 0.001 and 0.000). Conclusion Laparoscopic radiofrequency ablation improved the long-term clinical outcomes and decreased the serumal level of VEGF and MMP-2.
