OBJECTIVE:
To explore the applications of imaging examination on rib fracture sites in forensic identification.
METHODS:
Features including the sites, numbers of the processed imaging examination and the first radiological technology at diagnosis in 56 cases of rib fractures from 163 injuries were retrospectively analyzed.
RESULTS:
The detection rate of the rib fractures within 14 days was 65.6%. The initial detection rate of anterior rib fracture proceeded by X-ray was 76.2%, then 90.5% detected at a second time X-ray, while the detection rate of CT was 66.7% and 80.0%, respectively. The initial detec- tion rate of rib fracture in axillary section proceeded by X-ray was 27.6%, then 58.6% detected at a second time X-ray, while the detection rate of CT was 54.3% and 80.4%, respectively. The initial detection rate of posterior rib fracture proceeded by X-ray was 63.6%, then 81.8% detected at a second time X-ray, while the detection rate of CT was 50.0% and 70.0%, respectively.
CONCLUSION
It is important to pay attention to the use of combined imaging examinations and the follow-up results. In the cases of suspicious for rib fracture in axillary section, CT examination is suggested in such false X-ray negative cases.

Objective:To analyze the reasons for unplanned resection of soft tissue sarcomas and explore the treatment strategies for cancer surgery. Methods: The study included 105 patients with soft tissue sarcomas admitted to the First Affiliated Hospital of Xinjiang Medical University between October 2009 and December 2012. The average age of the patients was 52 years old. Among the patients, 65 were males and 40 were females. Up to 82 patients underwent planned resection (Group A) in our hospital, and 23 underwent unplanned resection (Group B) in other hospitals. Wide excision and radical resection were conducted in Group A, whereas extended resection was performed in Group B. General data, tumor location and size, resection margin, local recurrence and metastasis, and survival were statistically analyzed in the two groups. Results:The proportion attaining the margin of wide excision was obviously lower in Group A than in Group B (P<0.05). The 3-year survival rate was significantly higher in Group B than in Group A (P=0.001). Within an average follow-up of 18 months (3 months to 36 months) in Group B, 12 patients died, including 9 with tumor metastasis and 3 with other diseases. Within an average follow-up of 23 months (5 months to 36 months) in Group A, 15 patients died, including 12 with tumor metastasis and 3 with other diseases. Conclusion:Compared with planned surgical operation, unplanned resection of soft tissue sarcomas often leads to inadequate resection margin, which results in a high incidence of local recurrence and an increased mortality. Thus, clinicians should attempt to avoid unplanned resection of sarcomas.

Objective:To retrospectively investigate the efficiency of Jinlong capsule combined with transarterial chemoemboli-zation for the treatment of advanced pancreatic carcinoma. Methods: Sixty advanced pancreatic carcinoma patients between January 2009 and May 2013 were randomly assigned into the experimental group (n=30, Jinlong capsule combined with transarterial chemoem-bolization) and the control group (n=30, transarterial chemoembolization). Both groups were subjected to superselective pancreas artery chemotherapy with GEMZAR at a dose of 1.0 g/m2. Results:The overall response rate (CR+PR) was 53.3%and the control rate was 70%(CR+PR+SD) (CR 0, PR 16, SD 5) in the experimental group, whereas those in the control group were 36.7%and 56.7%(CR 0, PR 11, SD 6), respectively. The short-term therapeutic efficacy was higher in the experimental group than in the control group (P<0.05). No significant difference in adverse reactions, including digestive reactions and myelosuppression, almost I-II degree, was observed be-tween the two groups (P>0.05). No significant difference in the Karnofsky performance status was observed between the two groups af-ter the treatment (P<0.05). The 24-month survival rate of the experimental group was 50.0%, whereas that of the control group was 33.3%(P<0.05). Conclusion:The application of Jinlong capsule combined with transarterial chemoembolization for the treatment of advanced pancreatic carcinoma showed good clinical effects.
