BACKGROUND: There are several ways for treating the trigeminal neuralgia, such as medication, block therapy and surgery, etc. But few reports throughout the world described stereotactic radiotherapy(SRT) for it, which is efficient, non-invasive and painless.OBJECTIVE: To investigate the improvement of SRT for trigeminal neuralgia.DESIGN: Case analysis based on patients.SETTING: X-knife Treatment Center, First Affiliated Hospital, Henan University of Science and Technology.PARTICIPANTS: Totally 30 patients with trigeminal neuralgia were selected from X-knife Treatment Center, the First Affiliated Hospital of Henan Science and Technology University between March 1999 and March 2002. All patients were diagnosed with CT or MRI, and no other diseases were found. Patients without obvious effect from a long-term medicine treatment or surgery were selected as the investigative subjects.METHODS: Thirty patients with trigeminal neuralgia wearing face cover were treated with non-coplanarity fractional stereotactic radiotherapy. The patients received 2 target regions and peripheral does of 60 - 75 Gy. 5 mm collimator and isodose curves referred to ranged from 85% - 90%.MAIN OUTCOME MEASURES: Results of therapeutic assessment and follow up.RESULTS: The follow up period ranged from 1 to 22 months. Among 30patients, 6 patients' symptoms were lightened or eased up over 12-24hours, 20 patients received a marked effect over 1 - 3 months, 4 patients'treatment effects were not obvious. The effect rate reached 87%. A patient occurred numbness in sick face, and a patient showed no obvious effect in the first treatment, but the efficacy became evident in the second treatment.CONCLUSION: It is efficient in the treatment of trigeminal neuralgia with stereotaetic radiotherapy and there is no special side effect.

Objective To investigate the clinical features , treatment regimen , and prognosis evaluation of tertiary peritonitis (TP). Methods Seventy-eight cases with TP were randomly enrolled into 2 groups, including the simple western medicine-treated group (32 cases) and the integrated traditional Chinese and western medicine-treated group (46 cases). The prognoses were evaluated according to the acute physiology and chronic health evaluationⅢ (APACHEⅢ, APⅢ) scoring. Results The mortality rate was 71.9% (23 of 32) in patients received the simple western medicine and was 32.6%(15 of 46) in patients received the integrated traditional Chinese and western medicine with significant difference between these two groups (P < 0.01). There was a significant correlation between AP Ⅲscore and actual mortality (r=0.73,P<0.01), and predicted mortality (r=0.76, P<0.01). Conclusions The therapeutic effect is acceptable and satisfactory for the TP patients received the integrated traditional Chinese and western medicine. The AP Ⅲ scoring system can be used to predict the prognosis of TP patients.

Objective To investigate the diagnostic value of serum Cystatin C for early detection of renal damage in patients with liver cirrhosis. Methods 24-h creatinine clearance (CCr), serum level of cystatin C (CysC) and serum creatinine were measured in 76 patients with cirrhosis and t-test,Pearson's correlation test and ROC curve were used to evaluate the diagnostic significance of Cys C.Results The increase in Cys C level was associated with a decrease of CCr in the patients. Both Cys C and SCr were inversely correlated with CCr ( CysC: r =- 0. 763, P < 0. 001; SCr: r=-0. 571,P<0.01). Meanwhile, the area under the ROC curve was significantly higher in Cys C than in SCr (0. 830 vs. 0. 612). Conclusion Cystatin C is a more accurate and sensitive marker of renal diagnosis in liver cirrhosis. Detection of Cys C level in cirrhotic patients is of great significance for the prevention of liver-kidney syndrome.

Objective To study the microscopic changes of white matter and the relationship between white matter changes and cognitive impairment in Alzheimer's disease (AD) using voxel-based analysis of DTI. Methods Thirty-sev?en patients with probable AD,and 32 normal controls(NC) were all examined by MMSE scores, and underwent a diffusion tensor imaging. The value of FA changes and the correlations between FA and MMSE scores were investigated. Results FA reduction was detected in the right frontal, temporal and parietal lobes as well as the thalamus, the bilateral cingu?lum, corpus callosum, precuneus, inferior parietal lobule, inferior patieto gyrus, supramaginal gyrus and hippocampus in AD. FA values in the right cingulum, left corpus callosum, left inferior temporal gyrus and the bilateral inferior parietal lobule, inferior patieto gyrus and precuneus were significantly decreased in AD than in the health control groups (P<0.05, FWE corrected). There was a positive correlation between the values of FA and MMSE scores(P<0.001,uncorrect?ed). Conclusion AD patients have significant reduction of FA values in the specific regions. There is a positive correla?tion between white matter changes and impairments of cognitive function.
