Objective:To explore the clinical signiifcance of the protection of superior petrosal vein (SPV) in the microneurosurgery for acoustic neuroma. Methods:From January 2009 to July 2011, 149 cases of acoustic neuroma microsurgery were observed. hTe difference in hematoma in surgical area, cerebellar hematoma and cerebellar edema were compared between a SPV without protection group (SPVWP group, n=8) and a SPV protection group (SPVP group, n=141). Results:In the 149 patients with acoustic neuroma, the SPV was reserved in 141 patients. In the SPVWP group (8 patients), hematoma in the surgery area occurred in 4 patients, cerebellar edema in 5, and cerebellar hemorrhage in 3. In the SPVP group (141 patients), hematoma in the surgery area occurred in 40 patients, cerebellar edema in 56, and cerebellar hemorrhage in 12. hTere was signiifcant difference in the incidence of cerebellar hemorrhage (χ2=3.84, P=0.05), no signiifcant difference in the incidence of hematoma in the surgical area (χ2=0.646, respectively, P=0.422), and no significant difference in the incidence of cerebellar edema (χ2=0.611, P=0.434) between the SPVWP group and the SPVP group. Conclusion:In acoustic neuroma surgery, the SPV should be protected, which may reduce the risk of cerebellar hemorrhage.

Objective To observe the expression of adrenomedullin (ADM) mRNA in hepatic tissue of rats with acute necrotizing pancreatitis (ANP) complicated with hepatic injury.Methods Sixty-four SD rats were randomly divided into control group and ANP group with 32 rats in each group.In ANP group,ANP model was induced by retrograde injection of 5％ sodium taurocholate into biliopancreatic duct of rats.Rats in control group only received sham operation and pancreas manipulation.All the rats were sacrificed at 3,6,12,24 h after the operation.The serum levels of amylase,alanine aminotransferase (ALT),aspartate aminotransferase (AST) and ADM were detected.Pathological changes in pancreatic and hepatic tissue were examined.The expressions of ADM mRNA in hepatic tissue were evaluated by fluorescence quantitative PCR.Results The serum concentrations of amylase,ALT,AST were (7229 ±968),(174.2 ±28.0),(657.7 ± 139.0) U/L,which were significantly higher than those in control group [(2036 ± 292),(104.3 ± 22.1),(419.7 ± 86.3) U/L],and the difference between the two groups was statistically significant (P ＜ 0.05 or P ＜0.01).Pathological injury of pancreas and liver tissue in ANP gradually aggravated with time,and the pathological scores at 12 h were (11.60 ± 1.51),(2.60 ± 0.89),which were significantly higher than those in control group (1.20 ± 0.77,0),and the difference between the two groups was statistically significant (P＜0.01).The serum concentrations of ADM in ANP group increased at 3 h after ANP induction,and reached (38.53 ± 6.25)pg/ml at 12 h,which was significantly higher than that in control group [(28.99 ±3.92)pg/ml] ; the concentrations of ADM in liver tissue increased at 3 h after ANP induction,and reached (3.00 ± 1.49) at 6 h,which was significantly higher than that in control group (1.04 ± 0.20),and the difference between the two groups was statistically significant (P＜0.05 or P＜0.01).Conclusions The expression of ADM mRNA in rat 's hepatic tissue increases in the early stage of ANP,and the serum concentration of ADM also increases.

Objective To discuss the preservation and clinical significance of petrosal vein in microsurgical operation of acoustic neuroma. Methods 147 patients with acoustic neuroma were operated, with internal decompression of the tumor firstly then dissected the tumor with surrounding structures, the petrosal vein were protected well in 143 cases and failed to protect in 4 cases. Results No hemorrhagic infarction in cerebellar was observed in 143 cases with intact petrosal vein. One case occurred with extensive cerebellar edema, which has gait disturbance after 18 months follow-up. The other three cases occurred with vein infarction and hemorrhagic edema after petrosal vein damage. One was dead and the other two were recovered well after decompression of posterior cranial fossa. One has no significant neurological deficit after 33 months follow-up, while the other has difficulty in line walking after 12 months follow-up. Conclusion Petrosal vein should be well protected in the operation of acoustic neuroma, the decompression of posterior cranial fossa should be considered if petrosal vein failed to protect.

Objective:To study the effect of microsurgery for parasellar menningiomas and to analyze the impact factors of recurrence. Methods:Clinical and follow-up data in a consecutive series of 134 patients with parasellar meningiomas were retrospectively analyzed. Results:A total of 109 patients (81.3%) had radical removal (Simpson grade I and II), and 116 patients were followed up for an average period of 81.6 months. The mean quality of life score (KPS) was 91.9, 90 patients regained full daily activity and 16 patients were able to take care of themselves. Oculomotor paralysis occurred in 7 patients, epilepsy in 8, and another 9 patients suffered hemispheral paralysis. Tumor recurred atfer the radical removal in 12 out of the 96 follow-up patients (12.5%). Tumor progressed atfer subtotal removal in 12 out of the 20 follow-up patients (60%). Tumor with cavernous sinus (CS) invasion had significantly higher risk of recurrence campared with non-CS invasion (P=0.043). The recurrence rate increased with the pathological grade (P<0.01). Conclusion:Patients with parasellar meningiomas undergoing microsurgical resection may have a good long-term function outcome. For most patients, total removal by microsurgery is the ifrst choice. Careful follow-up is needed if tumor invaded the CS and radiosurgery is proposed for WHO grade 1 and 2.

OBJECTIVE: To explore the effective intracranial surgical method for hemifacial spasm which can be operated more safely and easily. METHOD: Twenty-five cases of hemifacial spasm underwent intracranial facial nerve root combing scraping by improved retrosigmoid approach. The compressing vessels were found in 10 cases and could be removed easily. Both microvascular decompression and facial nerve root combing scraping were performed to reduce recurrence. The other cases with perforating artery or without any compressing vessels underwent the facial nerve root combing scraping and cutting off partially for about 1/6 to approximately 1/5 neural fibers. RESULT: Hemifacial spasms were obliterated in 22 cases (88%) after operation, obviously relieved in 2 cases (8%), invalid in 1 case (4%). Varied facial nerve paralysis was observed in 25 patients, but no hearing disturbance and other serious complication occurred. Follow-up for 2 to approximately 8 years showed there were recurrences in 2 cases (8%) and the facial nerve paralysis of 25 cases recovered in 1 to approximately 6 months after operation. CONCLUSION The facial nerve root combing scraping is an effective and safe microsurgical procedure which has wide-ranged indication and less complication. It is very important to select suitable treatment for the patient individually during the operation to improve the efficacy and lower the risk.
