Objective To analyze and compare images of radial head fracture of 50 patients acquired by computed radiology(CR),coronal plane and axial plane of CT scan.And to determine routine plane of CT scan for radial head fracture.Methods Images of of radial head were acquired by CR,coronal plane and axial plane of CT scan on 50 patients with radial head fracture initially diagnosed by orthopedists. classify all the cases of radial head fracture into type Ⅰ、Ⅱ、Ⅲ and Ⅳ according to the classification proposed by Mason.Results The positive incidence of CT and CR were 96%(48)and 78%(39) respectively.Cases of 94%o(47)through CT coronal scan and 82%(41)eases through CT axial scan were exactly classified.Conclusion The designation of the plane of CT scan is significant to the classification of the radial head fracture.Coronal plane CT scan can meet the need of imaging clinical classification and is recommended to be routine plane of radial head fracture.In order to ensure the exact classification axial plane and 3D reconstruction technique should be added for type Ⅲ and type Ⅳ of radial head fracture.

OBJECTIVETo evaluate the safety and efficacy of individual cylindrical abdominoperineal resection (CAPR) for locally advanced low rectal cancer.

METHODSFrom June 2011 to February 2012, 11 patients with locally advanced low rectal cancer underwent individual CAPR. There were 7 male and 4 female patients, aged from 32 to 74 years with a median of 64 years. Forty-seven patients underwent classic CAPR from January 2008 to February 2012. Preoperative and postoperative parameters such as clinical information of patients, tissue morphometry and complications were compared.

RESULTSIn the individual surgical group, 6 patients were treated with one side levator ani muscle totally or partially reserved, 3 patients with sacrococcyx reserved, and 2 patients with dissection close to the anterior rectal wall. Compared with classical surgery, the individual surgical specimens of horizontal section area ((2197 ± 501) mm(2)) and intrinsic muscle layer outer area ((1722 ± 414) mm(2)) were small, but the difference was not statistically significant (P = 0.150 and 0.167). The operative time, intraoperative blood loss, circumferential resection margin, total cross sectional tissue area, cross sectional tissue area outside the muscularis propria and bowel perforation rate between the two groups were not significantly different. Individual CAPR showed less incidence of chronic perineal pain (2/11, χ(2) = 6.116, P = 0.013) and sexual dysfunction (2/9, χ(2) = 4.412, P = 0.036) compared with classic CAPR.

CONCLUSIONSIndividual CAPR has the potential to reduce the risk of chronic perineal pain and sexual dysfunction without influencing the radical effect when compare with classic CAPR for the treatment of low rectal cancer.

Objective To evaluate the clinical efficacy and safety of amifostine on elderly acute leukemia patients receiving chemotherapy.Methods Fifty-eight patients with acute leukemia treated with chemo-therapy and amifostine were recruited in this study and then divided into two groups, 28 cases in elderly group (≥60 years) and 30 cases in control group (<60 years).All the patients were given amifostine 600 mg· m-2 through intravenous injection 15 to 30 minutes prior chemothe-rapy for 4 cycles.The data of the influence of amifostine on chemotherapy-induced adverse reactions as well as patients′blood pressure were compared in two groups.Results There was no statistical difference in incidence rates of chemotherapy -induced adverse reactions in two groups (P>0.05).After chemotherapy, there were 82 (80.4%) and 102 (80.3%) cases showing decreasing systolic blood pressure in elderly group and control group, respectively, and 71 ( 69.6%) and 83 ( 62.9%) cases showing decreasing diastolic blood pressure ( P >0.05).Conclusion The application of amifostine on elderly acute leukemia patients who has received chemotherapy is safe and could relieve chemotherapy-induced adverse reactions.

Objective To investigate the clinical efficacy and safety of CHOP chemotherapy regiment combined with thalidomide in the treatment of aggressive non-hodgkin′s lymphoma.Methods Seventy-two cases of aggressive non-hodgkin′s lymphoma were recruited in this study and randomly divided into control group ( n =35 ) and treatment group (n=37). Patients in the control were given CHOP chemotherapy ( cyclophosphamide 600 mg ? m-2 intravenous injection, day 1+epirubicin 40 mg? m-2 ntravenous injection, day 1+vinblastine 1.4 mg? m-2 ntravenous injection, day 1+dehydrocortisone 50 mg? m-2 , orally, day 1-7).Patients in the treatment group were given CHOP chemotherapy regiment combined with thalidomide ( thalidomide 200 mg, day 1 -14, orally, at the second phrase thalidomide 400 mg, day 1-14).After 4 cycles treatment, the objective response rate, 1 and 2 year survival rate and chemotherapy associated toxicity were assessed between the two groups. Results The objective response rate were 78.38% and 57.14% in the treatment and control group respectively with the treatment group statistical higher than control group( P<0.05). The 1 and 2 years survival rate were 65.71%and 40.00%in the control group which was significant lower than that in the treatment group(1 and 2 years survival rate 81.08%, 62.16%, P<0.05) .The chemotherapy associated toxicity such as granulopenia, nausea and vomiting, alopecie and et al had no statistical difference between the two groups (P>0.05).Conclusion CHOP chemotherapy regiment combined with thalidomide can improve the objective response rate without increasing the toxicity in treatment of aggressive non-hodgkin′s lymphoma.

Objective To evaluate the effects of ultrasound-guided transversus abdominis plane (TAP) block on postoperative analgesia and early recovery in patients undergoing retroperitoneoscopic urologic surgeries. Methods This was a randomized, controlled, double-blinded trial. Eligible patients scheduled for retroperitoneoscopic urologic surgeries were randomly assigned to two groups. Group TAP received ultrasound-guided TAP block with 0.5% ropivacaine 20 ml at 30 minutes before surgery, and Group C received TAP sham block with normal saline. All patients received retroperitoneoscopic urologic surgeries under general anesthesia. The primary outcome was the severity of pain after surgery. Secondary outcomes included opioids consumption, analgesics, postoperative nausea and vomiting, time to Foley catheter removal and to passage of flatus, length of post-anesthesia care unit stay and hospital stay. Results Eighty patients completed the study, forty cases in each group. Compared to the Group C, the Group TAP had lower visual analogue scale pain scores within two postoperative days (all P<0.05). They also had less consumption of intraoperative fentanyl (2.0±0.5 vs. 3.8±0.7 μg/kg, P<0.05), reduced incidence of postoperative rescue analgesic usage (12.5% vs. 45.0%, P<0.05), and lower incidence of postoperative nausea and vomiting within postoperative 48 hours (12.5% vs. 25.0%, P<0.05) when compared to the Group C. In addition, Group TAP had a shortened post-anesthesia care unit stay (25±8 vs. 49±12 minutes, P<0.05), and a greater proportion of patients discharged within postoperative three days (57.5% vs. 35.0%, P<0.05). Conclusion Preoperative ultrasound-guided TAP block is an effective technique to improve postoperative analgesia and early recovery in patients undergoing retroperitoneoscopic urologic surgeries.

Seasonal outbreaks of airsacculitis in China's poultry cause great economic losses annually. This study tried to unveil the potential role of Avian metapneumovirus (AMPV), Ornithobacterium rhinotracheale (ORT) and Chlamydia psittaci (CPS) in avian airsacculitis. A serological investigation of 673 breeder chickens and a case-controlled study of 430 birds were undertaken. Results showed that infection with AMPV, ORT, and CPS was highly associated with the disease. The correlation between AMPV and CPS were positively robust in both layers and broilers. Finally, we determined the co-infection with AMPV, ORT, and CPS was prevalent in the sampled poultry farms suffering from respiratory diseases and the outbreak of airsacculitis was closely related to simultaneous exposure to all three agents.

Objective: To compare the effects of 3 treatment strategies (emergent surgery, self-expanding metallic stents, self-expanding metallic stents plus neoadjuvant chemotherapy) on postoperative anal function and quality of life in patients with complete obstructive left hemicolon cancer. Methods: A retrospective cohort study was conducted. Clinical data of patients with complete obstructive left hemicolon cancer admitted to General Surgery Department of Beijing Chaoyang Hospital between January 2017 and October 2019 were retrospectively collected. Patient inclusion criteria: (1) complete obstructive left hemicolon cancer was confirmed through clinical manifestation and abdominal computed tomography; (2) adenocarcinoma was confirmed by postoperative pathology; (3) emergent radical resection of primary tumor was performed with temporary stoma, or radical resection of primary tumor and primary anastomosis was performed without stoma, 7 to 14 days after completion of insertion of self-expanding metallic stents. Patients who did not receive stoma reversion after emergent operation were excluded. According to different therapies, patients were divided into three groups: emergent surgery (ES) group, self-expanding metallic stents (SEMS) group and self-expanding metallic stents plus neoadjuvant chemotherapy (SEMS+NAC) group. Wexner score for incotinence (higher score indicates the worse anal function), Vaizey score (>10 indicates fecal incontinence) and low anterior resection syndrome (LARS) scale (higher score indicates the worse anal function) were applied to evaluate anal function of patients among groups at postoperative 1-, 6- and 12-month. EORTC QLQ-C30 questionnaire was used to assess the quality of life. Risk factors of decreased anal function were identified by logistic regression analysis. Results: A total of 72 patients were enrolled, including 27 (37.5%) patients in ES group, 23 (31.9%) in SEMS group and 22 (30.6%) in SEME+NAC group. The baseline characteristics including age, gender, tumor location, comorbidities, total blood loss, operation time and postoperative complications, were comparable among groups, except that the proportion of laparoscopic surgery was significantly lower in ES group (4/27, 14.9%) than that in SEMS (15/23, 65.2%) and SEMS+NAC group (16/22, 72.7%) with significant difference (P<0.001). The follow-up ended up to October 2020, and the overall follow-up rate was 79.2% (57/72). No significant differences existed in the Wexner score of patients among groups at postoperative 1-, 6- and 12-month (all P>0.05). The Vaizey scores at postoperative 1-month in ES, SEMS and SEMS+NAC group were 7 (0-17), 3 (0-7) and 4 (0-8) respectively with significant difference (H=18.415, P=0.001), and the scores in SEMS and SEMS+NAC groups were significantly lower than that in ES group (both P<0.05), while no significant difference existed between SEMS and SEMS+NAC group (P>0.05). Vaizey scores at postoperative 6- and 12-month among 3 groups were not significantly different (both P>0.05). The LARS scores at postoperative 1-month in ES, SEMS and SEMS+NAC groups were 20 (0-37), 15 (0-24) and 16 (0-28) respectively with significant difference (H=3.660, P=0.036), and the scores in SEMS and SEMS+NAC groups were significantly lower than that in ES group (both P<0.05), while no significant difference existed between SEMS and SEMS+NAC groups (P>0.05). LARS scores at postoperative 6- and 12-month among 3 groups were not significantly different (both P>0.05). The QLQ-C30 score revealed that the social function of patients in SEMS group and SEMS+NAC group was significantly better than that in ES group (both P<0.05), while no significant difference existed between SEMS and SEMS+NAC group (P>0.05). The logistic regression analysis revealed that only ES was an independent risk factor of decreased anal function (OR=2.264, 95% CI: 1.098-4.667, P=0.027). Conclusion: Compared to ES, SEMS may improve quality of life and short-term anal function of patients with complete obstructive left hemicolon cancer.
