Purpose: Observe the varities of lymphocyte subgroup of patients suffering from primary hepatic carcinoma ( PHC) during the treatment by hepatic arterial chemoembolization (TACE) and Hyperthemia Peritoneal Perfusion (THPP). Methods: Twenty seven patients were treated with TACE and THPP a week after TACE. We tested for lymphocyte subgroup three times with the flow cytometry (FCM) for pre-TACE, post-TACE and THPP a month later. The control group, twenty seven patients, were also tested for lymphocyte subgroup three times with the TACE. Results: The lymphocyte subgroup among the patients suffering from PHC were disordered. CD4+,CD4+/CD8+.CD19+NK+ were decreased, (P

Objective To evaluate the possibility of keyhole approaches for surgical treatment of petroclival meningiomas. Methods We retrospectively analyzed our experience in 14 cases with petroclival meningiomas surgically treated from May 2003 to January 2004. Eight tumors involved the upper and middle clivus.five tumors were attached to the entire width of clivus and one tumor involved the middle and lower cilvus. The tumors infiltrated into parasella regions or cavernous sinus in six cases simultaneously. Retrosigmoidal keyhole approach was selected to remove the tumors in 6 cases, and subtemporal keyhole approach was selected in 2 cases,while the combined retrosigmoidal and subtemporal keyhole approaches were applied in other six cases. Results Gross total resections of the tumors were achieved in 8 cases, subtotal resections in 4 cases, large resection in two cases who had recurrent tumors. Postoperatively, neurological intact or unchanged were found in 8 cases. The main surgical complications were mild facial palsy (4 cases) , abducent dificits (3 cases) ,temporary oculomotor nerve dificits (2 cases),and lower cranial nerve palsy (1 case). One patient died from disseminated intravascular coagulation (DIC) two weeks after surgey. There were no CSF leakage and infections after surgery in all cases 11 to 19 months follow-up studies demonstrated the great improvement of the Ⅲ and Ⅶ nerve deficits,but minor improvement in the Ⅵ nerve deficits. Conclusion According to the location and extension of the tumors, retrosigmoidal or subtemporal keyhole approaches or their combined can be selected for surgical treatment. These keyhole approaches can expose sufficiently the petroclival region, shorten the surgical time, and minimize the complications. Combined usage of minimally invasive techniques including the keyhole approach and radiosurgey in the treatment of the petroclival meningiomas is suggested.

Objective　To discuss the surgical strategy for giant petroclival meningioma.　Methods　Retrospective analysis of operation and prognosis of 32 patients with petroclival meningioma with a diameter of more than 4.5 cm was carried out.The patients were divided into two groups: suboccipital retromastoid approach and skull base surgical presigmoid sinus approach. Duration of surgery, degree of tumor removal, and postoperative neurological complications were compared between the two groups.　Results　The percentages of radical and subtotal tumor removal in the two groups were not statistically significant. Less time of operations in the presigmoid sinus approach group and mild postoperative neurological sequelae in the suboccipital retromastoid approach group were observed. Karnofsky prognosis scale of the patients at the dismiss time was higher in the suboccipital retromastoid approach group (P＜0.01).　Conclusions　The degree of dissection of giant petroclival meningioma is correlated with tumor nature, blood supply, and adherence to the brain stem. Suboccipital retromastoid approach is suitable for giant petroclival meningioma. Total tumor removal should not increase neurological impairment; if radical dissection is impossible, the tumour may be reduced to less than 3 cm in diameter so as to achieve good results of postoperative radio therapy.

Objective To solve the difficulty of intubation of nasojejunal feeding tube under digital subtraction angiography (DSA) system when conventional methods were failed.Methods Seventy-one patients who failed to place the nasojejunal feeding tube by single guide wire under DSA conventional methods.With the methods of decreasing the stomach volume,changing the body posi-tion,and using a catheter or gastrointestinal motility,the nasojejunal feeding tube was placed into the proper position (more than 30cm far away from Treitz or gastrointestinal anastomosis).Results All the procedures were successfully accomplished.No compli-cations,such as throat damage,abdominal pain,perforation and hemorrhage of digestive tract were found.The mean duration under DSA was four minutes (2-7min).Conclusion With the help of various methods above,we can improve the success rate of intuba-tion and reduce the duration of the nasojejunal feeding tube placement,when conventional methods were failed.

BACKGROUND: Exogenous neural stem cells (NSCs) can repair nerve and promote recovery of neurofunction following cerebral hemorrhage.OBJECTIVE: To observe the growth and development of NSCs in vitro, to evaluate the survival, migration and differentiation of transplanted NSCs surrounding hematoma and the possible recovery function of NSCs, and to investigate the repairing effect of NSCs on damaged neurofunction in cerebral hemorrhage model rats.DESIGN: Completely randomized grouping design and controlled animal study,SETTING: Department of Neurosurgery, Huashan Hospital, Fudan University.MATERIALS: Eighteen adult healthy male SD rats weighing 280-320 g were provided by Shanghai Animal Center of Chinese Science Academy. BrdU was provided by Neomarkers Company; rat-anti-glial fibrillary acidic protein (GFAP) and rabbit-anti-microtubule-associated protein-2 (MAP-2) by Chemicon Company.METHODS: This study was performed at the Laboratory of Anatomy and Histology & Embryology, Shanghai Medical College,Fudan University from February to December 2006. The NSCs was isolated, cultured, and evaluated from hippocampus of day E14fetal SD rats. Eighteen rats were randomly divided into control group, PBS group and NSC transplantation group. Cerebralhemorrhage rat models were established via injection of autoiogous arterial blood in caudate nucleus. Thirty minutes after model establishment, 5 μ L NSC suspension with the concentration of 2×1011 L-1 was transplanted at four points surrounding hematoma cavity in the NSC transplantation group. Transplantation of PBS and NSCs was the same as autoblood transplantation. Thirty minutes after model establishment, injuries at the four points were performed, and nothing was injected in the control group.MAIN OUTCOME MEASURES: Neurofunction was evaluated with forward limb scale and turning scale just soon after transplantation and at 1, 3, 5, 14, and 28 days after transplantation. Brain was colleted by anesthesia 28 days after model establishment.Differentiation of transplanted NSCs was detected through testing GFAP, MAP-2, and BrdU by using immunohistochemistry.RESULTS: ①Neurofunction scores: There was no significant difference 5 days after model establishment (P＞0.05). However, the scores were significantly improved in the NSC transplantation group 14-28 days after model establishment (P＜0.05).②lmmunofluorescent double labeling: Apoptosis ceils around hemotoma in the NSC transplantation group were less than those in the PBS group. BrdU and MAP-2 or GFAP-positive ceils were observed in cerebral tissue sections, and this suggested that NSCs could survive, migrate and differentiate in host brain and differentiate into neurons or astrocytes.CONCLUSION: NSC Transplantation contributes to the recovery of neurofunction in cerebral hemorrhage rats through differentiation into neurons or astrocytes.
