Objective To investigate the effect of hyperbaric oxygen( HBO) in craniotomy for traumatic brain injury. Methods The 90 patients with traumatic brain injury who received craniotomy in our hospital from March 2012 to September 2014 were divided into the obser-vation group(51 cases) which received HBO therapy additionally and the control group(39 cases). The remission rate of brain edema,GCS score,incidence of lung infection,infarction incidence and subdural effusion incidence at the same course of HBO treatment between the two groups were observed and compared. Rsults The remission rate of cerebral edema of observation group was higher than that of control group after a course of HBO treatment. And 6 days,9 days,12 days and 15 days after the course of HBO treatment,the GCS scores of observation group/control group were 8. 2/7. 8,9. 8/9. 0,11. 2/10. 3 and 12. 2/12. 0,respectively. The lung infection incidence of study group was lower than that of control group. Conclusion HBO treatment can improve the remission rate of brain edema and GCS scores, and it can reduce lung infection incidence in craniotomy for traumatic brain injury.

Objective To investigate the effect of video-assisted thoracoscopic surgery( VATS) in thoracic disease,and the feasibility to carry out VATS for basic hospital. Methods The data of VATS treatment were collected to compare the differences between study group and control group,and evaluate the the feasibility to carry out VATS for basic hospital. Results The operation time was (100. 75±22. 72) min, blood loss was (54. 27±26. 21) mL,postoperative drainage was (920. 67±171. 99) mL. The postoperative complications were fewer,post-operative hospital stay was shorter,incision time was shorter(P=0. 000) and pain scores was lower(P=0. 000) in study group than that in control group. Basic hospital has the capacity to conduct this technical. Conclusion VATS is feasible to carry out in basic hospital.

Objective To investigate the effecacy of open reduction internal fixation in cases with rib fracture. Methods The pain scores,respiratory related clinical indicators change of 81 rib fractuure cases underwent open reduction internal fixation surgery were ob-served. A comparison was made between the surgical group and the non-surgical group of 37 cases on pain scores trend and hospital stay. Re-sults All operations were successfully completed and postoperative recovery was good. Postoperative pain scores and respiratory rate was sig-nificantly lower(P=0. 000),Oxygen saturation was significantly higher(P=0. 002),the proportion of expectoration difficult,dyspnea and ac-tivities inconvenience were significantly lower(P<0. 05). Pain scores of surgical group significantly decreased after surgery peak hours that was the fourth day hospitalized,but the overall decline of pain scores in non-surgical group was slow. The hospital stay between the surgical group and the non-surgical group was not significantly different(P=0. 084). Conclusion The efficacy of open reduction internal fixation is significant to rib fracture with exact surgery indications,and appropriate timing of surgery is the fourth day after admission.

Objective:To investigate the relationship between the positive surgical margin and clinical factors such as neoadjuvant hormonal therapy after robot-assisted laparoscopic radical prostatectomy (RARP) in high-risk patients with prostate cancer.Methods:The clinical data of 164 patients with high-risk prostate cancer being performed RARP by one surgeon were analyzed retrospectively in our hospital from January 2016 to January 2022. The mean patient’s age was (65.3±6.2) years old, mean body mass index (BMI) was (25.6±3.0) kg/m 2, the median value of total prostate specific antigen (tPSA) before operation was 18.6(11.3, 31.3)ng/ml, the median value of Gleason score before operation was 7 (7, 8), the median value of prostate volume was 29.3 (22.4, 40.2) ml, and the clinical stage was T 2aN 0M 0-T 4N 0M 0. 80 patients with prostate cancer were treated with neoadjuvant endocrine therapy. All of them were treated with complete androgen blockade with a median course of 3 months. Univariate analysis was used to analyze the correlation between age, BMI, prostate volume, neoadjuvant hormonal therapy, preoperative tPSA, clinical stage, Gleason score before operation and positive surgical margin. Then multivariate logistic regression was used to further analyze the independent risk factor of positive surgical margin after RARP. Results:The postoperative pathological diagnosis included pT 2 stage in 111 cases (67.7%), pT 3a stage in 15 cases (9.1%), pT 3b stage in 25 cases (15.2%), pT 4 stage in 13 cases (7.9%). No lymph node metastasis was noticed in all patients. The Gleason scores included 6 in 11 cases (6.7%), 3+ 4 in 26 cases (15.9%), 4+ 3 in 36 cases (22.0%), 8 in 17 cases (10.4%), 9-10 in 24 cases (14.6%), un-evaluation due to endocrine therapy in 50 (30.5%). The positive surgical margin of high-risk patients with prostate cancer was 44.5% (73/164). Univariate analysis showed that the neoadjuvant hormonal therapy, tPSA and clinical stage were correlated with positive surgical margin ( P<0.05). Multivariate logistic regression analysis showed that non-neoadjuvant hormonal therapy, preoperative tPSA>20ng/ml and clinical stage>T 2b were independent risk factors for positive surgical margin of high-risk patients with prostate cancer. Stratified analysis showed that when the preoperative tPSA was 10-20 ng/ml(21.1% vs.55.9%, P=0.014), the clinical stage was T 2c(29.6% vs.49.1%, P=0.040), the Gleason score before operation was 7(19.4% vs.54.1%, P=0.003), the positive surgical margin of high-risk patients in the neoadjuvant hormonal therapy group was significantly lower than that in the non-neoadjuvant hormonal therapy group ( P<0.05). Conclusions:Non-neoadjuvant hormonal therapy, preoperative tPSA>20 ng/ml and clinical stage>T 2b were independent risk factors for positive surgical margin of RARP in the high-risk patients with prostate cancer. For high-risk patients with preoperative tPSA of 10-20 ng/ml, clinical stage of T 2c and Gleason score before operation of 7, neoadjuvant hormonal therapy has important clinical significance in reducing the positive surgical margin of RARP.
