OBJECTIVE: To explore the application value of postmortem multi-slice spiral computed tomography (MSCT) in cases of fall from height through observing and analyzing the injury features of the fall and reconstructing the process of the fall based on the the above procedure. METHODS: One real fatal case due to fall from height was fully examined using MSCT and three-dimensional reconstruction technique. Analyzing the manner and cause of death through combination of MSCT and systemic autopsy was also implemented. The differences between autopsy and MSCT in getting information of injuries were compared. RESULTS: Fractures involving multiple body regions and liver rupture were found through MSCT and three-dimensional reconstruction. The autopsy got the same results with imageological examination. The case of death was deduced to be fall leading to systemic polytrauma. CONCLUSION Application of MSCT can be used as the complimentary for traditional autopsy in the analysis of injury manner of fall from height.

OBJECTIVETo establish a quality control method of Fuan oral liquid.

METHODSHigh-performance capillary electrophoresis (HPCE) was used to determine the content of feruild acid in Herba taraxaci, and thin-layer chromatography (TLC) was performed to identify Herba taraxaci and Bupleurum chinense. The condition of HPCE was optimized with a fuse silica capillary tube (70 microm x 60 cm) and 20 mmol/L sodium tetraborate buffer (pH9.18) at a constant voltage of 12 kV and temperature at 25 degrees celsius;, with the detection wavelength at 313 nm.

RESULTSClear spots were displayed on TLC. The calibration curve was linear in the range of 8-40 microg/ml for ferulic acid (Y=360.5-207.4, r=0.9997, n=5). The average recovery rate exceeded 95% with a RSD<3% (n=3).

CONCLUSIONThis method is simple and specific with a good reproducibility for quality control of Fuan oral liquid.

OBJECTIVE To investigate the HIV infections states in tumor patients for clinical diagnosis,treatment and to prevent HIV infection in the tumor hospital.METHODS The result of HIV detection in tumor patients from Dec 2000 to Aug 2006 was analyzed by the review statistics analysis.RESULTS Totally 48 101 tumor paients were detected,and the number of tumor patients with positive HIV antibody result was 51(0.106%).Among the positive patients there were 21 cases with blood transfusion history,14 cases with blood donating experience,2 cases with both these two kinds of experiences and 14 cases without the two kinds of experiences.Their rate was separately 41.0%,27.5%,4.0% and 27.5%.Most of the HIV positive patients had no clinical synptoms.CONCLUSIONS The HIV positive rate of patients with blood transfusion or blood donating is significantly higher than the patients without these experiences.The routine detection for the HIV before the operation,blood transfusion or other traumatic detection is very necessary.

Objective To study the prognostic influencing factors for intravenous thrombolysis combined with endovascular interventional therapy in patients with acute moderate to severe cerebral infarction. Methods From September 2013 to December 2015,the clinical data of 179 patients with moderate to severe acute cerebral infarction treated with intravenous thrombolysis combined with endovascular interventional therapy at the Cerebrovascular Disease Center,Shanghai Changhai Hospital were analyzed retrospectively. They were all treated with intravenous thrombolysis combined at least 1 endovascular interventional therapy (intra-arterial thrombolysis,mechanical thrombectomy or stenting)within 4. 5 h after onset. The patients with mRS ≤2 were divided into a good prognosis group (n = 71),those with 3≤mRS≤ 6 were divided into a poor prognosis group (n = 108)according to the modified Rankin Scale (mRS) scores after 3 months of treatment. The clinical data of both groups were analyzed,including age,sex,previous history,the National Institutes of Health Stroke Scale (NIHSS)score and Alberta stroke program early CT score (ASPECTS)immediately before and after treatment. The influencing factors of prognosis were further analyzed with multivariate Logistic regression analysis. Results The rate of good prognosis was 39. 7%(71 / 179). There were significant differences in age,history of transient ischemic attack at 1 week before the disease onset,the NIHSS score,and ASPECTS score before thrombolysis (62 ± 14 years vs. 71 ± 11 years,8. 4% (6 / 71)vs. 1. 9% (2 / 108),16 ± 6 vs. 19 ± 6,and 9. 5 ± 1. 0 vs. 8. 5 ± 1. 9,respectively;all P < 0. 05). There were no significantly difference in other stroke risk factors between the 2 groups (all P > 0. 05). There were significant differences in the NIHSS score immediately after treatment,24 h intracranial hemorrhage transformation,and intraparenchymal hemorrhage between the good prognosis group and the poor prognosis group (10 ± 3 vs. 15 ± 7,7. 0%[5 / 71]vs. 28. 7%[31 / 108],and 0 vs. 12. 0%[13 / 108];all P < 0. 01). Multivariate Logistic regression analysis showed that the age (OR,1. 047,95% CI 1. 014 -1. 081;P = 0. 005),NIHSS score immediately after treatment (OR,1. 121,95% CI 1. 050 -1. 196;P =0. 001)were the prognostic risk factors for intravenous thrombolysis combined with endovascular interven-tional therapy for moderate to severe cerebral infarction. The ASPECTS on admission (OR,0. 382,95% CI 0. 233 -0. 627;P < 0. 01)was the protective factor. Conclusions The age and the NIHSS score immediately after treatment are the prognostic risk factors for intravenous thrombolysis combined with endovascular inter-ventional therapy for moderate to severe cerebral infarction. With the increase of age and the NIHSS score after treatment,the prognosis of patients is even worse. With the increase of ASPECTS score at admission,the prognosis is better.

Objective To evaluate the efficiency and safety of mifepristone and gestrinone in subsidiary treat- ment after endometriosis surgery.Methods Totally 151 patients diagnosed as endometriosis with conservative surgery treatment or laparoscopic operation were divided into three groups;49 cases in the group of mifepristone re- ceived mifepristone tablets 10mg every day for 6 months from the first week of postoperation,60 cases in the group of gestrinone received gestrinone capsules 2.5mg twice every week for 6 months.Cases in the group of control did not receive any postoperative medical treatment.The duration of follow-up after surgery was censored at 3～18 months.Patients'controlling rate of ache symptoms and signs,clinical efficiency,recurrence rate,sex hormone level, menstrual and weight changes,liver and renal functions were recorded and compared.Results The follow up rate is 97.4 %,the efficacious rate and symptoms controlling rate of mifepristone group and gestrinone group were 78.7 %, 93.1% respectively,which of the control group were 34.8 %,58.7 % respectively.There were significant differ- ences,x~2=44.31,P

Objective To evaluate the efficacy of radiosynovectomy with 32P colloid in haemophilic synovitis of adolescents. MethodsRadiosynovectomy with 32P colloid was primary performed on 26 male haemophilic patients(26 joints),whose average age was 16 years(11 to 21 years).The average dose of 32P colloid was 2.1 mCi(1.0 to 3.0 mCi). Results After 6-month interval,haemarthrosis was reduced by no less than 30% in 23 patients,with a total efficacy of 88.5%.The mean frequency of haemarthrosis was reduced from 1.9 per month of presynovectomy to 0.3 per month of postsynovectomy(P

AIM: To make a contrast and then analyze the difference of optical coherence tomography (OCT) before and after vitreomacular traction syndrome (VTS) was performed.METHODS: The clinical date of 11 evaluable eyes of 11 patients with VTS who were diagnosed by OCT and underwent 25G vitreous surgery from January 2013 to January 2014 were retrospectively analyzed.Patients were followed up for an average of 6mo, to observe the visual acuity and OCT examination of the patient before and after operation.We compared the changes of retinal thickness and local morphology before and after operation.RESULTS: After vitreous retraction, 6 eyes improved, 2 eyes do not improve.One eye received macular membrane traction, in the operation the macular epiretinal membrane peeling, retrial membrane stripping and the triamcinolone acetonide intravitreal injection were given, but after the operation, the vision does not improve.Two eyes received vitreous combined with retinal macular membrane traction.In the operation, macular epiretinal membrane stripping was given, after the operation, visual acuity improved.The proportion of those with visual acuity of 0.1 or more increased from 46% before to 73% after the operation.Before operations, the mean central macular thickness was 619.27±195.13μm, 239.12±143.84μm after, which decreased significantly (P<0.05).CONCLUSION: Vitrectomy can effectively relieve the vitreous traction of the macula, and can prevent further decline in visual acuity and reduce macular edema as well as improve the visual acuity of some patients.So, OCT has important guiding significance on the diagnosis and prognosis of this group.

OBJECTIVE: To explore the application value of postmortem multi-slice spiral computed tomography (MSCT) by observing and analyzing the injury features in the traffic accident victims. METHODS: Ten traffic accident victims were scanned with whole body MSCT. The systemic autopsy was subsequently performed to compare with the results of MSCT. The advantages and disadvantages of autopsy and MSCT for obtaining the information of traffic accident injuries were then analyzed. RESULTS: MSCT could reveal 3D shape of fractures clearly and detect air accumulation in different positions of the body, which showed the obvious advantages compared with autopsy. However, the resolution of MSCT was limited compared to the detection of organ and soft tissue injuries. CONCLUSION A combination of MSCT and autopsy is the best way for determining the manner and the cause of death in traffic fatality victims.
