Objective:To sum up the characteristics of cerebrospinal fluid and brain CT findings of viral encephalitis in children, and provide guidance for clinical diagnosis and treatment of viral encephalitis.Methods: 117 cases of viral encephalitis were selected in our hospital and the results were analyzed by statistical analysis of cerebrospinal fluid and CT in children with viral encephalitis in order to compare the results of cerebrospinal fluid examination and CT examination.Results:Cerebrospinal fluid examination showed that the increased intracranial pressure were 52.14%(61/117), protein>0.5 g/L are 36.75%(43/117), elevated white blood cell levels were 57.26%(67/117), the neutrophils increased 33.33% (39/117), lymphocytes increased 31.62%(37/117), and the sugar concentration <3.3 mol/L are 14.53% (17/117). Head CT in the diagnosis of abnormalities in children were 98 cases, in which 21 were mild abnormal, 57 were moderately abnormal and 20 cases were severe abnormalities. Abnormal cerebrospinal fluid diagnosis rate of 94.02% was significantly higher than the rate of CT abnormalities 83.76% and the difference was statistically significant (x2=6.231,P<0.05).Conclusion: The abnormal rates of CT examination in the diagnosis of viral encephalitis were higher in patients with viral encephalitis. The combination of the two examinations could be more comprehensive than that of the patients with the disease and focus. It could be benefit for clinical treatment.

0.05).In terms of toxicity,Aleucocytosis,phlebitis and constipation were more common in NP group while thrombocytopenia and skin rash were more common in GP group(P

Objective To analyze the diffusion properties of acute cerebral stroke to understand the effects of infarct and hematoma on diffusion-weighted MR images of patients with acute cerebral stroke. Methods 25 acute cerebral infarcts, 22 intracranial hematomas and 5 hemorrhagic infarctions were studied with CT, conventional and diffusion MR imaging. The DWI and ADC parameters of acute cerebral stroke were analyzed. Results The DWI images of 25 acute cerebral infarcts, 1 hyperacute hematoma, 2 acute hematomas and 3 subacute hematomas were hyperintensity, and that of 8 early subacute hematomas were hypointensity. The DWI images of early stage of 4 chronic hematomas were hyperintensity at center and hypointensity at periphery, and that of late stage were hypointensity. The DWI images of acute hemorrhagic infarctions had both the hyperintensity and hypointensity. Meanwhile, the ADC images of majority of the lesions were hypointensity. Conclusion DWI could reflect the diffusion properties of different types of cerebral strokes and play an important role in evaluating the strokes.

Objective To investigate the extraction of DNA from urine and urine stains and typing.Methods DNA was extracted from urine and urine stains with Chelex-100 extraction method and QIAamp Mini Kit.STR loci were typed after amplification by PCR procedures with Profiler Plus Kit.Results STR loci could be well typed in DNA extracted from the urine,which was fresh or preserved properly for less than 12 hours.Satisfactory DNA typing could be made in 50% of the urine preserved for two days.No typing results were obtained in the samples kept for seven days or much longer time,and typing was rarely available using urine stains.Conclusion DNA extracted from the fresh urine can be typed,which may be used in forensic identification.

Objective To investigate the clinical application of magnetic resonance cholangiopancreatography(MRCP) in diagnosis of obstructive jaundice.Methods Thirty-three patients with obstructive jaundice were examined by MRCP and the accurate rate of MRCP was evaluated according to the result of operation and pathology examination.Results The positive rate of the orientation diagnosis of MRCP in obstruction was 100%(33/33).The accurate rates of qualitative diagnosis for benign disease and malignant obstructive jaundice were 87.5%(21/24) and 90%(9/10) respectively.The general qualitative diagnose accordance rate was 87.9%(29/33).Conclusion MRCP is simple,hurtless and safe for the diagnosis of obstructive jaundice and it deserves generalization in the clinical application.

Objective For the purpose of exploring the influence exerued by the amount of template DNA on the results of automatic fluerescent detection. Method For the purpose of buiding the optimal amount of template DNA amplified, we have analyzed different amount of template DNA (9947A) by 3100 Genetic Analyzer with the multiplexing Profiler Plus Kit. Results The optimal amounts of template DNA amplified were between 0.31ng and 2. 5ng by using 3100 Genetic Analyzer. Conclusion It will produce the incorrect analytic results if the amounts of template DNA were too high or too low.

Objective To investigate the levels of matrix metalloproteinase-9 (MMP-9) expression in different grades of glioma and the relationship with MRI characteristics. Methods Thirty-one patients of glioma confirmed pathologically were divided into two groups: low grade group (grade Ⅰ and Ⅱ, n=20) and high grade group (grade Ⅲ and Ⅳ, n=11). MMP-9 expression levels were evaluated with immunohistochemical staining. Plain and enhanced MR scan were performed in all patients before operation. Peritumoral edema index (EI), enhance percentage (EP) and the tumor's maximum diameter were recorded as characteristics of MRI. Results The expression levels of MMP-9, EI, EP and the tumor's maximum diameter were significantly higher in the high grade group than those in the low grade group (t=6.312, 4.405, 6.286 and 5.026, respectively, all P＜0.05). The expression of MMP-9 were found significantly correlated to EI, EP and the maximum diameter of tumor (r=0.516, 0.554 and 0.676, respectively, all P＜0.05). The expression levels of MMP-9 were significantly different between tumors with heterogeneity and even signal (t=2.637, P＜0.05), but not between tumors with unclear border and clear border definition (t=0.906, P＞0.05). Conclusion MMP-9 expression have close relationship with invasion of glioma. EI, EP, the maximum diameter and signal of tumor can reflect the level of MMP-9 expression, and may be used to estimate tumor's malignant behavior, being able to provide the evidence for future clinical operation.

ObjectiveTo evaluate the sufficiency of dialysis and nutri ti onal status of 44 end-stage renal disease (ESRD) with urea metabolic parameters such as TACurea,KT/V and PCR.MethodClinical data were collecte d and analyzed with statistic methods.ResultsTACurea and PCR w ere significantly lower in patients in insufficient dialysis group than those in sufficient dialysis group.There was no statistical difference between the two g roups in terms of KT/V.PCR was not influenced by KT/V in sufficient dialysis gro up,while it was significantly influenced by KT/V in insufficient dialysis group. ConclusionTACurea and PCR are significant indicators to assess whether the blood dialysis is sufficient or not in the long run.KT/V can direct ly indicate the effectiveness of single dialysis.Therefore,it is the best indica tor for adjusting the dialytic strategy.However,it is not important if the dialy sis is not sufficient.

Objective To discuss microsurgical experience for transsuboccipital retrosigmoid sinus approach of large acoustic neuronomas,and improve the rate of tumor removing,and facial nerve and auditory nerve preserving Methods A retrospective analysis of 39 patients with acoustic neuronomas which were more than 4 cm in diameter were treated by microsurgery between January 1994 and December 2000 Tumor's excision was performed by transsuboccipital retrosigmoid sinus approach The surgical main points of transsuboccipital retrosigmoid sinus approach,and their experience of total removal,and rate of facial nerve and auditory nerve preservation were described Results The tumors were totally removed microsurgically in 34 patients,the total removal rate was 87 2%,and subtotal removal in 5 patients Facial nerve was anatomically preserved in 31 cases,the rate of facial nerve preservation was 79 5%,but the function of facial nerve was recovered in 22 cases (56 4%) The auditory nerve was preserved anatomically in 15 cases (38 5%) and functionally in 7 cases (17 95%) Conclusions An minimally invasive microsurgical treatment are crucial for increasing a satisfactory living quality of the patients It is considered that the total removal rate of tumor,the preservative rate of facial nerve and auditory depend upon microsurgical technique and intraoperative facial nerve monitoring in acoustic neuromas surgery
