OBJECTIVE: To analyze the features of orbital fracture and to discuss its forensic expertise points. METHODS: One hundred and thirty cases of simple orbital fracture from 2010 to 2012 collected from one public security bureau were retrospectively analyzed such as age, gender, tools, position and morphology of the fracture, periorbital and orbital compound injury and the follow-up results after 6 months. RESULTS: In the 130 cases, the wounded were mainly young men and hit by fist. The fracture of simple medial orbital wall accounted for up to 81.5% in all cases. In the periorbital and orbital compound injury, laceration and contusion of eyelid and ethmoidal cellules and maxillary sinus always occurred. After 6 months follow-up, there were 30 cases of comminuted fracture remained enophthalmos compared with the uninjured side. CONCLUSION It is inappropriate to judge the fracture of simple medial orbital wall as minor injury. We should judge the degree of simple orbital fracture after the injury is stable. Detailed ophthalmology inspection is necessary for forensic expertise of simple orbital fracture.

Objective To compare the image quality and scanning dose of time-subtraction and dual-energy-subtraction cerebral CT angiography, and to assess clinical application value of both methods. Methods Plain and enhanced scanning were performed on 60 patients suspected cerebral vessel diseases with dual-source CT. Dual-energy mode with tube voltages of 140 and 80 kV was used in enhanced scanning, and data of two different energy were collected in one scanning. ①Traditional removed-bone digital subtraction (time-subtraction) with plain and 80 kV enhanced scanning data were obtained. Volume render (VR) and maximum intensity projection (MIP) reconstruction were finished; ②Direct removed-bone digital subtraction (dual-energy subtraction) with 80 kV and 140 kV enhanced scanning data were obtained. VR and MIP reconstruction were finished. The image quality of VR and MIP was divided into 4 grades, and were compared as well as average effective radiological dose. All the diseases were confirmed with surgery or DSA. Average effective radiological dose was compared with time-subtraction and dual-energy subtraction. Results Internal carotid artery trunk and branch and Willis circles were displayed clearly with two methods in 60 cases. No significant difference was found (P>0.05) between total quality score of the two methods. The size, shape, neck and axis point of aneurysm in 24 cases were clearly displayed, so as the shape and extent of abnormal vessel bolus in 4 cases, while arteries and veins were also clear in artery-vein malformation; ③The average radiological dose was (26.60±0.50)mSv in time-subtraction and (22.40±0.50) mSv in dual-energy subtraction. Conclusion The normal, abnormal vessels and diseases can be clearly displayed at time-subtraction and dual-energy subtraction CTA. The effect of dual-energy-subtraction is better than that of time-subtraction CTA in no-cooperation patients, and the radiological dose is lower in dual-energy CTA.

Investigation of simvastatin and its related substances was carried out using a reversed phase ultra performance liquid chromatography/tandem mass spectrometry method. The identification of impurities in simvastatin was performed with a triple-quadrupole mass spectrometer, with an electrospray ionization (ESI) source in the negative/positive ion mode. A total of 12 compounds were characterized in commercial samples, among which 2 impurities had never been reported. All the impurities were deduced based on the MS fragment pathways of simvastatin and the biosynthetic pathway of lovastatin. This work provides very useful information for quality control of simvastatin.

Objective To investigate the expression and significance of signal pathway Wnt/β-catenin in prostate cancer stem cells.Methods Prostate cancer tissues,hyperplasia prostate tissues and normal prostate tissues were collected,then prostate cancer stem cells were selected from cell suspension in the culture system of serum-free medium by magnetic activated cell sorting system.Immunohistochemical SP test,RT-PCR and Western blot were applied to test the expression of Wnt and β-Catenin mRNA or protein in prostate cancer stem cells,hyperplasia prostate tissues and normal prostate tissues.Results The protein expression of Wnt and β-Catenin was higher in prostate cancer tissues compared with that in hyperplasia prostate tissues and normal prostate tissues;mRNA expression of Wnt and β-Catenin was higher in prostate cancer stem cells (4.57±0.83,3.93±0.78) than in hyperplasia prostate tissues (1.32±0.35,1.48±0.44) and normal prostate tissues (1.00±0.12,1.00±0.11),and the difference was statistically significant (F＝13.287,12.648,P＝0.000).Protein expression of Wnt and β-Catenin was higher in prostate cancer stem cells(0.87±0.10,1.12±0.23) than in hyperplasia prostate tissues(0.39±0.08,0.64±±0.11) and normal prostate tissues (0.33±0.09,0.45±0.10),and the difference was statistically significant (F＝16.625,14.417,P＝0.000).Conclusion Signal pathway Wnt/β-catenin is stimulated abnormally in prostate cancer stem cells,causing the occurrence of prostate cancer,providing a new research direction for treatment of prostate cancer.

Objective: To investigate the hyponatremia incidence in patients with ruptured intracranial aneurysms and the correlation with Fisher grading and cerebral vasospasm. Methods: Totally 150 patients with ruptured intracranial aneurysms from March 1998 to May 2001 were divided into anterior communicating artery (ACoA) group,posterior communicating artery (PCoA) group and middle carotid artery(MCA) group according to the sites of aneurysms.The patients were treated with GDCs interventionally and the incidences of hyponatremia were analyzed. Results: The incidences of hyponatremia in 3 groups were 48%(32/67),15%(8/52) and 16%(5/31),respectively; The incidences of severe hyponatremia of 3 groups were 30%(20/67),6%(3/52) and 6%(2/31), respectively. In ACoA group, the incidences of hyponatremia in Fisher grade Ⅲ-Ⅳ and Ⅰ-Ⅱ were 67%(20/30) and 32%(12/37) and the incidences with and without vasospasm were 71%(24/34) and 24%(8/33), respectively. Conclusion: The ACoA group has a significantly higher incidence of common and severe hyponatremia than the other groups. In ACoA group,hyponatremia is significantly more often in Fisher grade Ⅲ-Ⅳ cases and those with vasospasm.

AIM: To investigate the effect of Fas ligand on reendothelialization in the rat carotid artery with balloon withdrawl injury. METHODS: Balloon withdrawal injury was used to establish the denuded carotid artery rat model in twelve SD rats and then six SD rats were treated with ?-gal virus supernatant (?-gal group), and the others were treated with FasL virus supernatant (FasL group). After fourteen days, Evans blue dying was conducted via injection through rat tail vein at 30 min before the animals were killed, then fixation perfusion in situ was performed with 10% formalin and specimens were obtained. Histologic observation and morphometric analysis were made. RESULTS: The reenothelialization area (RA) of arterial balloon injury and the ratio of the reenothelialization area to the total area ((RA/TA)) significantly increased in FasL group compared with those in ?-gal group (P

Objective To investigate whether epithelial-mesenchymal transition (EMT)is involved in the anti-invasion and anti-metastasis effects of curcumin on MDA-MB-2 3 1 breast cancer cell line and further analyze the underlying mechanisms.Methods MTT method was used to detect the anti-proliferative effect of curcumin on MDA-MB-2 3 1 cell line induced by lipopolysaccharide (LPS).The morphological changes were determined by optical and transmission electron microscopy,respectively.The expressions of Vimentin,E-cadherin,NF-κB and Snail were analyzed using RT-PCR and Western blotting.Results Curcumin could inhibit the occurrence of LPS-induced EMT of MDA-MB-2 3 1 breast cancer cell line, decrease the expression of LPS-induced EMT marker Vimentin and increase the expression of E-cadherin, resulting in the inhibition of in vitro cell motility and invasiveness.These actions were mediated by inactivating NF-κB-Snail signaling pathways.Conclusion Our data provide a new perspective of the anti-invasion mechanism of curcumin,indicating that the effect is in part due to its ability to inhibit the EMT process.
