Objective To discuss the effect of comprehensive intervention on the quality of life of esophageal cancer patients receiving radiotherapy.Methods 100 patients with esophageal carcinoma treated with radiotherapy for the first timewere selected between October 2012 and December 2014 in Nantong Tumor Hospital in Jiangsu Province and randomly divided into control group and observation group (n =50 in each group) with a random number table.In the control group,routine dietary instruction,fluid infusion support and symptomatic intervention were used;comprehensive intervention was added in the observation group.Scores of core quality of life questionnaire (QLQ-C30) and nutritional indexesbefore and after radiotherapy in the two groups were compared.Results There were no statistically significant differences in QLQ-C30 scores and nutritional indexes between the two groups before radiotherapy (all P＞0.05).After radiotherapy,the physical [(75.6 ±13.1) vs.(63.8 ± 12.4)] and emotional function [(61.9 ± 14.3) vs.(52.5 ± 13.7)],fatigue [(36.6 ± 13.2) vs.(45.8±15.0)],pain [(34.8±16.1) vs.(44.3±17.0)],insomnia [(49.2±15.7) vs.(57.2±14.3)],loss of appetite [(50.2 ± 16.2) vs.(59.0 ± 15.8)],nausea and vomiting [(21.5 ± 10.3) vs.(29.9 ±11.3)],general health status [(68.8 ± 13.4) vs.(58.2 ± 12.8)] inthe observation group were significantly better than in the control group (all P ＜0.05).Innutritional status,body weight [(59.3 ± 8.5) kg vs.(54.4 ± 7.3) kg],body mass index [(21.9 ±2.1) kg/m2 vs.(18.4 ±2.8) kg/m2],hemoglobin [(125.9 ± 8.9) g/Lvs.(107.3±9.5) g/L],albumin [(35.1±6.9) g/Lvs.(29.0±5.3) g/L],and prealbumin [(213.54 ±37.47) mg/L vs.(174.56 ±36.26) mg/L] in the observation group were all higher than thosein the control group after radiotherapy (all P ＜ 0.01).Conclusion Comprehensive intervention for esophageal cancer patients receiving radiotherapymay improve nutritional status,reduce esophagitis,thirsty,fatigue,loss of appetite and other symptoms,improve the quality of life,ensure the completion of radiotherapy.

Objective To investigate the cellular immunologic response of TH 17/Treg cells in the peripheral blood of pelvic tuberculosis patients and explore their roles in the pathogenesis of pelvic tuberculosis.Methods The intracellular flow cytometry was performed to evaluate the expressions of TH 17 and Treg cells in 46 pelvic tuberculosis patients and 25 healthy controls in childbearing age.Twenty-eight of the 46 pelvic tuberculosis patients were followed up to monitor the variation of the TH17/Treg cells after 3 months and 6 months of anti-tuberculosis treatment.Results The percentage of TH 17 cells in the peripheral blood of pelvic tuberculosis patients was (3.26 ± 1.30) ％ which was significantly lower than that of healthy controls [(4.92 ± 1.71) ％,P ＜ 0.01].The percentage of Treg cells in the patients was (5.18 ± 1.53) ％ which was significantly higher than that of healthy controls [(3.26 ± 1.10) ％,P ＜ 0.01].The percentage of TH17 cells in the pelvic tuberculosis patients after 6 months of treatment was (4.67 ± 1.75) ％ which was significantly higher than that in the patients before treatment and after 3 months treatment [(3.26 ± 1.30) ％,P ＜ 0.01 and (3.70 ± 1.06) ％,P ＜0.01,respectively].The percentage of Treg cells in pelvic tuberculosis patient after 6 months of treatment was (3.93 ±0.94)％ which was significantly lower than that in the patients before treatment and after 3 months of treatment [(5.18 ± 1.53)％,P ＜0.01 and (4.94 ± 1.51) ％,P ＜ 0.01,respectively].The percentage of Treg cells in the patients after 6 months of treatment was still significantly higher than that of controls (P ＜ 0.05).The TH 17/Treg ratio before treatment was significantly lower than that of healthy controls (P ＜ 0.01),and the TH 17/Treg ratio was increased after 3 months of treatment but it did not show significant difference compared with that before treatment.The TH 17/Treg ratio after 6 months of treatment (1.18 ± 0.34) ％ was significantly increased in contrast to those after 3 months of treatment and before treatment [(0.77 ± 0.21) ％,P ＜ 0.01 and (0.55 ± 0.13) ％,P ＜ 0.01,respectively].The TH 17/Treg ratio could not rise to the normal level even after 6 months of treatment.Conclusion Both the TH 17 and Treg cells may involve in the immunologic responses of pelvic tuberculosis patients and the imbalance of TH1T/Treg cells may remain persistently.

Objective: To explore the effect of hyperbaric oxygen preconditioning with different frequency on the survival rate of flap and ischemia-reperfusion injury in rats after transplantation, and to explore the best preconditioning conditions to improve the survival rate of rat flaps after transplantation. Methods: Thirty-six Sprague Dawley rats were randomly divided into four groups according to the random number table method, 9 groups in each group.Four groups of rats were pretreated with hyperbaric oxygen pretreatment for 0, 2, 4, and 6 days before the operation, control group, pretreatment 2 d group, pretreatment 4 d group, and pretreatment 6 d group. Taking the midline of the back of the rat as the axis, an ultra-long random flap with a pedicle at the tail end and about 1 cm from the superior iliac spine was designed and cut to a size of 10.0 cm×2.5 cm. The survival of the flaps in each group was observed and the final survival area and survival rate of the flaps were measured on the 7th day after surgery. On the 7th day after operation, the tissue was taken at a distance of 5 cm from the pedicle, and the histopathology was observed; The content of superoxide dismutase (SOD) and malondialdehyde (MDA) in flap tissue was detected by immunohistochemistry, and the expression rate of positive cells in each group was calculated. Immunofluorescence was used to detect the expression of interleukin-6 (IL-6) in the flap tissue. Results: On the 7th day after the operation, the survival area and survival rate of the transplanted flaps in the hyperbaric oxygen pretreatment group were significantly higher than those in the control group (P<0.05), and the pretreatment 4 d and 6 d groups were significantly higher than the pretreated 2 d group (P<0.05), but there was no significant difference between the pretreated 4 d group and the 6 d group (P=0.095). Pathological observation on the 7th day after operation showed that there was some necrosis in the control group, the vascular cells in the pretreated 2 d group had more vascular structures, and more neovascularization was observed in the pretreated 4 d group. The inflammatory cells were the least in the 6 d pretreatment group, and the neovascularization was the same as the pretreatment 4 d group. The absorbance A value of SOD in the control group was 0.009 7±0.000 3, and the positive expression rate was 20%, which was significantly lower than that in the hyperbaric oxygen pretreatment group. The difference was statistically significant (P<0.05). However, the absorbance A value of MDA in the control group was 0.055 1±0.003 0, and the positive expression rate was 55%, which was significantly higher than that in the hyperbaric oxygen pretreatment group. The difference was statistically significant (P<0.05). Among them, the SOD absorbance A value of the pretreated 2 d group was 0.023 8±0.003 0, and the positive expression rate was 30%, which was lower than the pretreatment 4 d group (absorbance A value 0.046 9±0.003 0, positive expression rate 35%) and 6 d group (absorbance A value 0.047 2±0.003 6, positive expression rate 40%), The MDA absorbance A value of the pretreated 2 d group was 0.037 2±0.003 2, and the positive expression rate was 30%, which was higher than the pretreatment 4 d group (absorbance A value 0.014 7±0.002 4, positive expression rate 5%) and 6 d group (absorbance A value 0.017 0±0.001 8, positive expression rate 10%), the difference was statistically significant (P<0.05). However, there was no significant difference in the expression of SOD and MDA between the pretreated 4 d group and the pretreated 6 d group (P>0.05). The expression of IL-6 in the hyperbaric oxygen pretreatment group was significantly lower than that in the control group (absorbance A value 44.937 0±0.594 0), the difference was statistically significant (P<0.05). The absorbance A value in the pretreated 2 d group was 41.698 0±0.724 0, which was significantly higher than the pretreatment 4 d group (absorbance A value 34.049 0±0.323 0) and 6 d group (absorbance A value 33.524 0±0.639 0). The difference was statistically significant (P<0.05). There was no significant difference in the expression of the pretreated 4 d group compared with the 6 d group (P=0.068). Conclusions Hyperbaric oxygen preconditioning can significantly promote the survival of rat flaps after transplantation. Preoperative hyperbaric oxygen preconditioning once daily for 4 consecutive days, can enhance the tolerance of flap tissue to ischemia and anoxia and reduce tissue ischemia-reperfusion injury.
