Objective To evaluate the short-term effects of three-dimensional conformal radiotherapy (3D-CRT) associated with transcatheter arterial chemoembolization (TACE) in the treatment of primary hepatic carcinoma and 3D-CRT associated with chemotherapy in the treatment of metastatic hepatic carcinoma. Methods In 52 patients with primary hepatic carcinoma, first of all a single TACE was conducted. Then after an interval of 2 weeks, the conformal radiotherapy was given, with a radiation dose of 2~3 Gy every fraction, once daily or once every other day and 3~5 fractions every week. The total radiation dose to the target was 42.2~60.0 Gy (mean, 52.2 Gy). Afterwards, 2 additional TACEs were given after the radiotherapy. In 35 patients with metastatic hepatic carcinoma, chemotherapy was carried out for 1 treatment course firstly. Then 3D-CRT was employed. After the radiotherapy, another 2 courses of consolidating chemotherapy were administrated. The patient continued with the chemotherapy for additional 3 treatment courses (a total of 6 courses) if efficacy evaluation showed the patient had responded to the chemotherapy. Results The response outcomes were: complete remission (CR) 23 0% (20/87), partial remission (PR) 39 1% (34/87), stable disease (SD) 34 5% (30/87) and progressive disease (PD) 3 4% (3/87), the response rate (RR) being 62 1% (54/87). Conclusions 3D-CRT with TACE for primary hepatic carcinoma and 3D-CRT with chemotherapy for metastatic hepatic carcinoma offers high local control rates and good short-term effects.

Objective To explore the adjustment of interleukin II combining lifein for CD+4 T lymphocyte, Th1 and Th2 of patients with malignant tumor. Methods CD+4 T lymphocyte were measured by flow cytometer. Th1 lymphocyte and Th2 lymphocyte were measured by ELISA. Thirty- eight patients with malignant tumor were enrolled in the study. Interleukin II were administered at the dose of 500 000 U, i.h Qd, from day 1 to day 5. Lifein were administered at the dose of 10mg/d, i.m Qd, from day 6 to day 21 or form day 6 to day 27. The count of CD+4 T lymphocyte, Th1 lymphocyte and Th2 lymphocyte were studied before treatment, 2 weeks and 1 month after treatment. Conduct ANOYA using SPSS software. Results The expression of CD+4 T lymphocyte in patients as with increase tendency. The counts of Th1 lymphocyte, Th2 lymphocyte and Th1/Th2 were not significantly different after treatment. Conclusions The dose of this treatment could enhance the count of CD+4 T, but it could not adjust the count of Th1 lymphocyte, Th2 lymphocyte. The target of treatment about interleukin II combining lifein for patients with malignant tumor is CD+4 T lymphocyte's other subsets.

Objective To address the mediating role of cognitive emotion regulation in the relationship between parenting styles and health risk behavior in left-behind children.Methods A total of 404 leftbehind children were surveyed with the egna minnen av barndoms uppfostran (EMBU),the cognitive emotion regulation questionnaire-Chinese version (CERQ-C) and the adolescent health related risky behavior inventory (AHRBI).Results (1) The whole average score of AHRBI was (1.47±0.24);the scores of positive and negative cognitive emotion regulation respectively were (10.52±2.56) and (9.51±2.55);the scores of Authoritative,authoritarian and permissive/neglecting parenting styles respectively were (44.06± 8.50),(18.89±3.44) and (10.15±2.32).(2)The health risk behaviors of left-behind children were negatively related with authoritative parenting style (r=-0.26 ～-0.46,P＜0.01) and positive cognitive emotion regulation(r=-0.19～-0.44,P＜0.01),and positively related with authoritarian parenting style,permissive/neglecting parenting styles(r=0.19 ～ 0.40,P＜0.05) and negative cognitive emotion regulation (r=0.25 ～0.51,P＜0.05).(3) Authoritative parenting style was positively related with positive cognitive emotion regulation (r=0.30 ～ 0.47,P＜0.01),and negatively related with negative cognitive emotion regulation (r=-0.21 ～-0.30,P＜0.01),while authoritarian and permissive/neglecting parenting styles were negatively related with positive cognitive emotion regulation (r=-0.11 ～-0.16,P＜ 0.05),and positively related with negative cognitive emotion regulation (r=0.12～0.40,P＜0.05).(4)The mediating effect of cognitive emotion regulation between Authoritative,authoritarian and permissive/neglecting parenting styles and the health risk behaviors of left-behind children respectively were 0.62(87％),0.40(75％) and 0.48(60％).Conclusion The results suggests that parenting styles impact the health risk behavior in left-behind children mainly via the mediating effect of cognitive emotion regulation.

Objective To compare the clinical effects of percutaneous foramen rotundum and percutaneous foramen ovale radiofrequency thermocoagulation (PRT) on maxillary neuralgia.Methods Eighty patients with primary maxillary neuralgia were randomly divided into puncture foramen (group A) and foramen rotundum through pterygopalatine fossa (group B).Visual analogue scale (VAS) scores,puncture time,surgical side effects,and complications were recorded before surgery,one week,and one,3,6 and 12 months after operation.Recurrent rate and excellent and good results were calculated one week,and one,3,6 and 12 months after operation.Results The operation time of group A was significantly shorter than that of group B (P＜0.05),however,complications (involved V1 and V3 branches) of group A were significantly higher than those of group B (P＜0.05).VAS scores of two groups showed no significant differences at each time points (P＞0.05).Recurrence rate of group A 3,6 and 12 months after surgery was 5.1％(2/39),7.8％(3/39) and 15.4％(6/39),respectively,which showed no significant differences as compared with that of group B (2.8％[1/36],11.1％[4/36] and 11.1％[4/36],P＞ 0.05).Rate excellent and good results showed no significant differences between each two groups one week,and 3,6 and 12 months after operation (P＞0.05).Conclusion Percutaneous punctures of the foramen ovale and foramen rotundum approach radiofrequency therrnocoagulation for the treatment of maxillary neuralgia are safe and effective operation methods;surgical complications in foramen rotundum approach are less than those in the foramen ovale approach.

Objective:To compare Jefferson-fracture reduction plate (JeRP) and micro titanium plate in the transoral single-segment fixation of unstable atlas fractures.Methods:From January 2008 to December 2020, 45 patients with unstable atlas fracture were treated by single-segment fixation through an oral approach with a JeRP or a micro titanium plate at Department of Orthopedic Surgery, General Hospital of Southern Theatre Command. They were 24 males and 21 females, aged from 15 to 67 years. By the Gehweiler classification, 11 atlas fractures were type Ⅰ and 34 type Ⅲ; by the American Spinal Injury Association (ASIA) classification, the spinal cord injury was grade D in 7 cases and grade E in 38 cases; by the Dickman classification, the atlas transverse ligament injury was type Ⅰ in 4 cases and type Ⅱ in 11 cases. Of the patients, 26 were treated by transoral single-segment fixation with a JeRP and 19 by transoral single-segment fixation with a micro titanium plate. The 2 groups were compared in terms of baseline data, operation time, blood loss, hospital stay, visual analog scale (VAS) for neck pain and atlas lateral mass displacement (LMD) before operation and at the last follow-up, and intraoperative and postoperative complications.Results:The 2 groups were comparable because there was no significant difference between them in the preoperative general data ( P>0.05). All patients were followed up for 12 to 55 months (mean, 21.8 months). Wound dehiscence or infection was observed in none of the patients after operation. About 12 months after operation, all fractures achieved bony union, neck pain basically disappeared, and neck movement had no obvious limitation. The hospital stay was (13.9±2.2) d for the JeRP group and (14.2±2.9) d for the micro titanium plate group, showing no significant difference between the 2 groups ( P>0.05). The operation time was (203.5±173.4) min and the blood loss (167.3±138.6) mL in the JeRP group, significantly more than those in the micro titanium plate group [(121.5±50.5) min and (98.4±57.2) mL] ( P<0.05). In the JeRP group, the preoperative LMD was (6.7±1.7) mm and the preoperative VAS score (6.8±1.0) points, significantly higher than the last follow-up values [(0.7±0.6) mm and (0.7±0.6) points] ( P<0.05). In the micro titanium plate group, the preoperative LMD was (6.6±1.5) mm and the preoperative VAS score (6.7±0.9) points, significantly higher than the last follow-up values [(0.9±0.6) mm and (0.8±0.7) points] ( P<0.05). However, there was no significant difference in the preoperative or the last follow-up comparison between the 2 groups ( P>0.05). Implant loosening was observed in one patient in the JeRP group while foreign body sensation in the throat was reported in one patient after operation in the micro titanium plate group. Conclusions:Both JeRP and micro titanium plate in the transoral single-segment fixation can lead to effective treatment of unstable atlas fractures. Compared with JeRP, the micro titanium plate can effectively shorten operation time and reduce blood loss due to its smaller size and lower incision.
