OBJECTIVE:
To evaluate the perioperative analgesic effects of parecoxib sodium in patients undergoing nasal endoscopic surgery.
METHOD:
In the randomized, double blind, controlled study, 120 patients undergoing septoplasty were divided into 3 groups (n = 40): A group received parecoxib at a dose of 40 mg by muscle injection 30 min before the operation followed by saline at the same volume every 24 h for 48 h; B group received parecoxib at a dose of 40 mg by muscle injection 30 min before the operation followed by 40 mg every 24 h for 48 h; C group received an equal volume of 0.9% saline at the same time points. Patients were assessed with respect to pain score (VAS), rescue analgesia requirement and the side effects during the operation as well as at 3, 24, 48 h after the surgery.
RESULT:
Intra-operative as well as the postoperative pain scores were less in the A group and B group than in the.control group. Compared with group A, group B had significantly lower VAS score at 24 h after the operation, however there were no significant difference on other time points. Fewer participants of both the A and B groups required rescue medication after operation.
CONCLUSION
Administration of parecoxib can provide ideal analgesic effects without serious adverse side effects at the perioperative period for patients who received nasal endoscopic operation. Intramuscular parecoxib (40 mg 30 min before the operation followed 40 mg qd for 48 h) designed as preoperative analgesia mode resulted in sufficient perioperative analgesia that deserves popularization in the clinical works.

Objective To prospectively study the dynamic variation of vascular endothelial growth factor (VEGF),the short-term efficiency and the tolerability of the esophageal cancer patients treated by radiotherapy combined with thalidomide.Methods The serum samples of 86 esophageal cancer patients were collected before,during and after the radiotherapy.The VEGF levels were assayed by enzyme-linked immunosorbent assay (ELISA).3 patients interrupted the treatment because of intolerance radiotherapy.Based on the changes of VEGF level,32 esophageal cancer cases whose VEGF levels increased or remained were assigned to the group to which thalidomide was given during the whole course of radiotherapy.The rest 51 patients whose VEGF level decreased received radiotherapy without thalidomide during the whole course.In addition,30 healthy cases were included in control group.Then the efficiency and safety of the introduction of thalidomide in radiotherapy were investigated. Results The VEGF levels of 86 esophageal cancer cases were significantly higher than the 30 healthy control cases ( t =5.07,P < 0.01 ),which were also correlated with the primary tumor size ( t =4.55,P < 0.01 ),lymph node metastasis ( t =7.50,P <0.01 ),histological type( F =3.40,P < 0.01 ) and clinical stage ( t =2.52,P < 0.0 l ).However,it was irrelevant to the lesion site,distant metastasis,X-ray pathologic type,gender or age ( P > 0.05).For the thalidomide involved group, the VEGF level after radiotherapy was significantly lower than during radiotherapy (t =2.37,P <0.05 ) with an effective rate of 71.88%.For the rest 51 cases without using thalidomide,the effective rate was 78.43% yet there was no significant difference between the VEGF levels during and after radiotherapy ( t =0.18,P > 0.05 ).62.50% patients reported symptoms of dizzy and burnout after using thalidomide,while this incidence was 15.69% for the rest patients (x2 =19.28,P =0.000).For the groups with or without thalidomide combination,the sleepiness incidences were 18.75%and 1.96%,respectively (x2 =5.168,P =0.023 ); the Ⅲ - Ⅳ grade esophagitis incidences were 12.50% and 11.76%,respectively (x2 =0.061,P =0.806) ; the Ⅱ - Ⅳ grade leukocyte decrease incidences were 6.25% and 9.80%,respectively (x2 =0.026,P =0.872) ; the Ⅲ - Ⅳ grade platelet descend incidences were 3.13% and 5.88%,respectively (x2 =0.002,P =0.965 ) ; the Ⅲ - Ⅳ grade nausea and vomiting incidences were 9.38% and 27.45%,respectively (x2 =2.913,P =0.088 ). No anaphylaxis was observed. Conclusions Thalidomide can decrease the VEGF expression level of esophageal cancer patients.Patients treated with thalidomide show good tolerance and compliance.

Objective To optimize the method for radiotherapy target delineation after breast cancer surgery, and to observe its advantage in raising work efficiency. Methods Ten physicians in our department were selected, and 20 patients who received breast?conserving surgery were randomly selected. The 10 physicians delineated the targets for these patients with the method in the control group and the method in the study group, and the time required for each delineation was recorded. The method in the control group was commonly used in daily practice and the method in the study group was optimized. The independent?samples t test was applied to compare the differences between the two groups. Results With the optimized method, the average time of delineation in the study group was less than that in the control group ( 51 min vs. 65 min, P=0. 029) . The time curves for delineation in the control group were relatively flat;the time curves for delineation in the study group were high at first, then decreased gradually, and finally became flat. The time for each physician to finish delineation skillfully was relatively stable, while in the study group, the time started to decrease after delineation for the first few patients, with an apparent learning process. Conclusions The optimized method for target delineation in breast cancer is feasible, reliable, and easy to master, and can increase work efficiency, which is more obvious in physicians with rich experience in delineation.

Objective:To analyze the prognostic factors of patients with Ⅰ B1-Ⅱ A cervical cancers after surgery and to assess the effects and adverse reactions of intensity-modulated radiotherapy(IMRT)combined with concurrent chemotherapy(CCRT). Methods:A retrospective analysis was performed based on the clinical and follow-up data of 362 patients with Ⅰ B1-Ⅱ A cervical cancers who were treated in Changzhou Second People′s Hospital from January 2009 to December 2019. Meanwhile, these patients suffered large primary tumors(LPT; tumors size: ≥4 cm), lymphatic vascular space invasion (LVSI), and deep stromal invasion(DSI; stromal infiltration depth: ≥1/2) after surgery and showed at least one intermediate-risk factor. Among these cases, 161 cases were treated with CCRT, 131 cases under-went single radiotherapy (RT), and 70 cases received unadjuvanted radiotherapy. The Kaplan-Meier method and the logrank test were adopted for univariate survival analysis, the binary logistic regression was used to analyze the recurrence risk, and Cox regression model was used for multivariate survival analysis. Results:The 3 and 5-year overall survival (OS) rates were 94.20% and 88.39%, respectively. The retrospective analysis showed that the risk factors of recurrence included tumor size ≥ 4 cm and poorly differentiated cancers( OR=3.287, 2.870, 95% CI: 1.366-7.905, 1.105-7.457, P<0.05). Compared with the treatment without adjuvant radiotherapy and RT, CCRT reduced the recurrence rate of tumors with tumor size of ≥ 4 cm, adenocarcinomas or adenosquamous carcinomas (pathological types), and poorly differentiated carcinomas( χ2=6.725-7.518, P<0.05). A multivariate analysis showed that the CCRT improved the recurrence-free survival ( HR=0.290, 95% CI: 0.128-0.659, P=0.003) and OS ( HR=0.370, 95% CI: 0.156-0.895, P=0.024). A subgroup analysis indicated that CCRT prolonged the OS of patients with tumor size ≥ 4 cm or poorly differentiated cancers compared to the patients receiving no radiotherapy or those treated with RT (χ 2=7.614, 5.964, P<0.05). Compared with the cases receiving single radiotherapy, those receiving CCRT did not suffer an increase in the incidence of hematology, radiation enteritis, and cystitis above grade 3 according to observation ( P>0.05). Conclusions:Among the intermediate-risk factors leading to the recurrence of postoperative cervical cancers, the factors of large primary tumors or poorly differentiated cancers affect the prognosis of patients.Compared with RT and the treatment without adjuvant radiotherapy, IMRT combined with concurrent chemotherapy can prolong the recurrence-free survival and overall survival of patients with large tumors or poorly differentiated cancers and adverse reactions induced are tolerable.

Objective To predict the tolerance range of set-up errors in clinical practice by predicting the virtual set-up errors of postoperative radiotherapy patients for breast cancer. Methods A retrospective analysis was made of the patients who underwent radiotherapy after breast cancer surgery in recent 3 years. According to different treatment method, 10 cases of breast cancer after modified radical mastectomy and 10 cases after breast conserving radical mastectomy were selected. The target area was delineated, the volume modulated radiation therapy plan was made, the virtual moving error of the center point of the plan was moved, and the maximum moving error was 5 mm by 1 mm step. After recalculating the dose, the corresponding data including the clinical target areas ( CT ) , CTV ( V50 ) , average heart volume, V20 of the affected lung and CTV volume were recorded. SPSS 19. 0 software was used for statistical analysis, and repeated measurement of variance analysis was used to analyze the changes of the actual dose in the target area after moving the center point. Linear regression analysis method was used to analyze the correlation between the CTV volume and the dose change after the CTV moving midline. Results The virtual set-up error had little influence on the axis direction of the approximate mammary tangent direction, while the vertical direction of the approximate mammary tangent direction had greater influence. After moving more than 3 mm on the vertical axis, the CTV ( V50 ) decreased to below 90%, which was lower than the general requirement for the target area of CTV. Statistical analysis of set-up errors in all directions showed that there was significant difference in dosimetric changes ( F=34. 182, 12. 877, 16. 443, 9. 846, 46. 829, 10. 122, 57. 931, P <0. 05) in all directions except the B direction of left breast set-up errors (P>0. 05). Between breast conserving surgery and modified radical mastectomy, there was little effect on target movement. Through correlation analysis, it was found that the volume of CTV in the target area of breast cancer patients was linearly related to the errors caused by the movement of B, C and B directions of left breast and right breast(F=5. 733, 18. 496, 6. 630, P<0. 05). Conclusions In postoperative radiotherapy for breast cancer, the errors perpendicular to the section of breast should be paid special attention to whether left or right breast. When the error of this direction exceeds 3 mm, CTV is obviously less than V50 below 83. 85%. The effect of set-up error on the dose of CTV was not related to the operation mode of breast cancer and there was no obvious correlation with the volume of the target area.

Objective:
To observe the pathological response in tumor tissues and the vascular endothelial growth factor (VEGF) changes in serum of patients with esophageal carcinoma receiving radiotherapy or concurrent chemoradiotherapy, and to investigate the relationship between these two factors and the prognosis of these patients.
Methods:
A total of eighty-nine patients with esophageal carcinoma treating with radiotherapy or concurrent chemo-radiotherapy were prospective included. Gastroscopy and biopsy were performed at 4 week of radiotherapy to assess pathologicalresponse. VEGF serum levels were measured by double antibody sandwich avidin-biotin ELISA prior to, at 4 week of, and 1 week after radiotherapy. The relationship between pathological response in tumor tissues and VEGF serum changes and the prognosis of the patients were analyzed. The survival curve and survival rate were respectively drawn and calculated by the Kaplan-Meier method, and the Log-rank test was used for survival analysis. Multivariate Cox proportional hazard model was used to analyze the prognostic factors.
Results:
Pathological responses were classified into two degrees: Non-CR responses (22 cases), and CR responses (67 cases). The 1-, 3- and 5-year OS rates in CR group and non-CR group were 77.6%, 46.3%, 35.2% (median OS: 30.0 months, 95%
