Objective To investigate the value of the imaging division and features of CT and MRI in the differential diagnosis of benign and malignant space-occupying lesions.Methods A retrospective analysis of the clinical and imaging data of 201 patients with orbital space-occupying lesions confirmed by pathology was conducted.Four sector method was used to analyze the distribution of the lesions.The shape,border and relationship with surrounding tissues,MRI signal,CT density,and calcification of the orbital wall were also analyzed.Results There was statistical difference in the distribution of lesions in each of the 4-sector between orbital benign lesions and malignant tumors(χ2总=48.93,P=0.000).Lesions located in separate orbital zone including extra-periosteum compartment (18 cases),optic nerve compartment (4 cases),intraconal compartment(39 cases) were benign.Benign lesions (64%, 66/103) were more than malignant lesions (36%,37/103) in 103 lesions located in extraconal compartment.Additionally,there was significance in the distribution in separate and mixed zones between benign and malignant lesions(χ2=25.559,P=0.000).Benign lesions (77%,127/164) were more than malicious lesions(23%,37/164) in 164 cases in separate zone.Malignant lesions (65%,24/37) were more than benignant lesions (35%,13/37) in the 37 lesions located in mixed zone.Signs of CT and MRI:the benign and malignant lesions were 140 and 61,respectively.The features of those lesions are as follows(ratio=benign lesions/ malignant lesions):regular morphology(ratio=93/10),clear boundary(ratio=108/24),eyeball-surrounded (ratio=24/39),bone destruction (ratio=4/11).Features of lesions including shape,border,eyeball-surrounded, bone destruction had significant difference between benign and malignant lesions,whereas no differences was observed in calcification,signal on T1WI or T2WI,displacement of the eyeball and the occurrence of single or bilateral lesions.Conclusion The characteristic distribution of orbital space-occupying lesions based on the 4-sector and the features of CT and MRI has a great value in the diagnosis.

Objective To assess the effects of different administration timing of prophylactic antibiotics on infections after hip arthroplasty. Methods 535 patients having undergone arthroplasty were divided into two groups: the experiment group (n=273)and the control group (n=262): The former groupwere administered with antibiotics until 24 hours postoperatively and the latter until 72 hours postoperatively. The two groups were compared in terms of postoperative infection rate. Results The infection rates in the experimental groupand the control group were 4.396%and 3..817%, with insignificant differencebetween them. Conclusion For those patients undergoing hip arthroplasty, extended administration of antibiotics after operation (over 48 hours) may not reduce the risk of recent the infection rate.

Objective:To investigate the efficacy of microsurgical treatment in cavernous sinus tumors.Methods:The clinical data of 87 patients with cavernous sinus tumor treated by microsurgery from January, 2010 to August, 2019 were analysed retrospectively. The surgical approaches and microsurgical skills for common tumors in Cavernous Sinus region were discussed. The follow-up included outpatient and telephone follow-ups, and the follow-up results were evaluated by KPS score.Results:Among the 87 cases, 57 were totally resected (65.5%), 14 were subtotal resected (16.1%) and 16 were major resected (18.4%). Hospitalisation ranged from 14 to 98 days, with an average of 29 days. Postoperative complications occurred in 30 cases with cranial nerve injury, 2 brain stem injury, 4 postoperative bleeding, 5 cerebrospinal fluid leakage, 4 infection, 1 Pituitary damage and 1 death. Prognosis and follow-up analysis showed 68 cases with KPS>60 and 66 with KPS>80 at 1 month after surgery; 74 with KPS>70 and 72 with KPS>80 at 3 months after surgery; 78 with KPS>80 by 12 months after surgery. During the follow-up period of 6-120 months, 3 cases died. Recurrence: 6 of incomplete resection of meningioma, were in 1-6 years after the surgery, 4 of incomplete resection of schwannoma in 1-8 years, 2 of pituitary adenoma respectively in 13 and 16 months after the surgery. There was no recurrence after reoperation. Two cases of chondrosarcoma, 3 of chordoma and 3 of germinoma were treated with radiotherapy, and during the follow-up, there was no progress of the focus. No tumor progression or recurrence was found in other cases during follow-up.Conclusion:Surgery of cavernous sinus tumor is difficult due to frequent postoperative complications. Reasonable preoperative plan, surgical approach and precise microsurgical techniques are the keys in reduction of postoperative complications and in the improvement of prognosis.

OBJECTIVE: Analyzing the clinical manifestation, diagnosis and management of isolated sphenoiditis in children, retrospectively, was to get more information of the disease and to supply correct treatment early. METHOD: The symptoms, signs and imaging data of seventeen cases with isolated sphenoiditis hospitalized in our department from June 2001 to January 2010 were analyzed retrospectively. RESULT: Nine out of seventeen patients had the chief complaint of headache, three patients had blood in nasal discharge and had a fever, and five patients had postnasal drip with headache and a slight fever. The disease lasted for three months to one year. Five patients showed nasal discharge in rhinologic examination, one patient had solitary polyps in sphenoethmoid recess, eight patients had adenoid hypertrophy and the last three patients showed no positive signs. CT scan or MRI revealed opacification in sphenoid sinus. Eight patients received normative antibiotic therapy and were cured. The rest nine patients received endoscopic sinus surgery. The complaints relieved after the surgery and there was no signs of recurrence in 1 to 5 years of follow-up. CONCLUSION Headache can be the chief and unique symptom of isolated sphenoiditis in children, which was easy to misdiagnose and miss diagnosis. CT or MRI was the evidence of diagnosis. Antibiotic therapy could be used for acute sphenoiditis. Patients with chronic sphenoiditis should receive endoscopic sinus surgery as early as better. From supraturbinal to sphenoid sinus natural ostia is the best way in sphenoidotomy.

Objective To investigate the relationship between inflammation and blood coagulation function in the patients with acute exacerbation of chronic cor pulmonale (AECCP) and discuss the potential mechanism and influence on the patients. Methods The present study was based on 30 healthy controls and 141 cases of AECCP in our hospital from January 2011 to June 2014.Levels of white blood cell (WBC), neutrophil (NEUT), high-sensitivity C-reactive protein (hs-CRP, Complement 3 (C3), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB) and thrombin time (TT) in the patients were determined. Results Compared with the healthy controls, the patients had higher levels of WBC, NEUT, hs-CRP, PT, APTT, FIB, TT (all P < 0.001) and lower level of C3 (P < 0.001). Significant positive correlations were found between the levels of WBC, NEUT and FIB (r = 0.196 and r = 0.199, both P < 0.05); hs-CRP and APTT, FIB(r = 0.234, P < 0.01 and r = 0.466, P < 0.001); C3 and FIB(r = 0.466, P < 0.001), and significant negative correlations were observed between the levels of C3 and PT, APTT, TT (r=-0.258, P<0.01;r=-0.279, P < 0.01 and r = -0.168, P < 0.05, respectively). Compared with the survival patients, the cases of death had higher levels of WBC and NEUT (both P < 0.01). The area under receiver operating characteristic curve of WBC and NEUT, predicting the prognosis, was 0.666 (95% CI 0.552, 0.780; P < 0.01) and 0.695 (95% CI 0.558, 0.801; P = 0.001) respectively. Conclusions Inflammation and blood coagulation function disorder usually coexist in the patients with AECCP, and are closely associated with the severity. Levels of both WBC and NEUT can be used as prognosis predictors for the patients.

OBJECTIVETo screen and identity genes related to CD133(+)CD200(+) colorectal cancer stem cells.

METHODSThe two subpopulations of colorectal cancer cells, namely CD133(+)CD200(+) and CD133(-)CD200(-) cells, were sorted and verified by flow cytometry. The gene expression profiles of CD133(+)CD200(+)and CD133(-)CD200(-) colorectal cancer cells were examined using Affymetrix Human U133 Plus2.0 genome-wide genechip. The differentially expressed genes between the two cell subpopulations were analyzed to identify the genes responsible for the main effect in association with colorectal cancer stem cells. Real-time quantitative PCR was performed to confirm some of the differentially expressed genes identified by genechip.

RESULTSThe genechip result showed that 655 genes were differentially expressed in CD133(+)CD200(+) colorectal cancer stem cells by at least 3 folds, including 290 up-regulated and 365 down-regulated ones. Bioinformatics analysis and gene co-expression network building identified 3 genes (MDM2, PRKACG, and CACNA1G) with specific expression in CD133(+)CD200(+) colorectal cancer stem cells, and this result was confirmed by real-time quantitative PCR analysis.

CONCLUSIONA specific gene expression profile of colorectal cancer stem cells has been established through screening and identifying genes related to CD133(+)CD200(+)colorectal cancer stem cells by gene genechip technique, which provides a basis for further study of gene targeting therapy of colorectal cancer.

Objective To explore the monitoring of cerebrospinal fluid (CSF) dynamics in a model of brain herniation induced by acute intracranial hypertension in Guangxi Bama-Mini pigs by phasecontrast cine magnetic resonance imaging (PC cine MRI).Methods Femoral artery blood were extracted from 10 pigs,and injected into the frontal and temporal parietal lobe to make a model of brain herniation induced by acute intracranial hypertension.The mean arterial blood pressure (MAP),intracranial pressure (ICP),and cerebral perfusion pressure (CPP) were monitored.Routine T1WI,T2WI,coronal,sagittal and cerebrospinal fluid flow sequence (fast PC cine slice) which positioned on the cervical 3 (C3) vertebral body as the center and perpendicular to the spinal scans were performed on all experimental animals before and after blood injection with 3.0T Magnetic Resonance Imaging.The ICP,MAP,CPP,the absolute values of CSF peak flow velocity and the absolute value of carotid peak flow velocity before and after blood injection were compared.Results The ICP,MAP,CPP,and the absolute value of CSF peak flow velocity before injection of autologous arterial blood were statistically significant as compared with those after blood injection [(6.80±2.044) mmHg vs (52.20±1.619) mmHg,(76.80±7.068) mmHg vs (142.80±12.399) mmHg,(70.00±6.074) mmHg vs (90.50±12.250) mmHg,and the absolute value of CSF peak flow velocity was (243.20±77.671) mm/s vs (201.40±55.482) mm/s,respectively,P＜0.01].The absolute value of the peak velocity of the carotid artery before blood injection was not statistically significant compared with that after blood injection [(876.80±239.908) mm/s vs (799.40±241.829) mm/s,P＞0.05].Conclusion After the formation of brain herniation induced by acute intracranial hypertension,the CSF flow in the C3 level spinal canal showed a low dynamic change,and the CSF flow velocity waveform was disordered and malformed.The non-invasive measurement of CSF dynamics by PC cine MRI can provide an important basis for the change of CSF dynamics in the model of brain herniation induced by acute intracranial hypertension,and provide a theoretical basis for further research on damage control neurosurgery in the future.
