Objective To study the feasibility of minimally invasive procedure for the management of dumbbel tumors of the cervical vertebral canal. Methods Fourteen cases of dumbbel tumors of the cervical vertebral canal were treated by the approch of semi-laminectomy. Results Twelve cases underwent total resections, one case underwent subtotal resection, another case underwent great part of resection. The vertebral artery was preserved well during the operation. Nine out of fourteen cases had followed up for 6～18 months. Neurological function was improvement in all cases. No recurrence or instability of spine was found. Conclusions The approch of semi-laminectomy has the advantages of minimal invasion, less bleeding, and no influence on stability of spine. It is a good choice for dumbbel tumors of the cervical vertebral canal

Objective The purpose of this study was to evaluate the outcome of surgical treatment for spinal cord tumors. Methods We retrospectively analyzed a series of 660 patients with 676 intra-spinal tumors who were treated surgically from February 1993 to December 2007. The tumors located at the cervical level in 231 patients,thoracic in 202,lumbar in 159,sacral in 9,cervico-thoracic in 16,thoracico-lumbar in 42,and lumbar-sacral in 17. Totally 699 operations were performed,including posterior bilateral laminectomy approach in 599,unilateral laminotomy in 71 and laminoplasty in 6 cases.Besides,23 additional operations via lateral or ventral-lateral were performed for resection of extra-spinal component of dumbbell shaped tumors. Results In this series,Schwannomas and meningiomas were the most common extramedullary tumors accounting for 76.5% of the cases [517/676,rate of total resection: 92.3% (477/517)]. The intra-medullary tumors accounted for 23.5% (159/676),in which astrocytomas and ependymomas were the most often observed [rate of total resection: 67.3% (107/159)]. The peri-operative mortality was 1.7% (11/660). The motor and sensory functions were found to be improved after operation in 77.8% (357/459) and 79.2% (397/501) respectively. The sphincter function was improved in 72.4% (215/297). The rate of pain relief was 93.3% (361/387). The follow-up periods ranged from 0.5 to 15.1 years in 582 patients with an average of 5.9 years;during the period,87.8% (499/568) of the patients had an ASIA impairment scale E neurological function. Conclusions Intra-spinal tumors locate mostly in the subdural-extramedullary space,with a majority are Schwannomas and meningiomas. The widespread application and availability of MRI investigation provide the physician with accurate localization of the lesion thereafter ensure a minimally invasive surgical treatment strategy keeping the stability of the spine while removing the tumors with an satisfactory outcome.

Ojective To evaluate the value of computed tomographic angiography (CTA) in the diagnosis of intracranial aneurysml with acute subarachnoid hemorrhage and in making a surgical plan. Methods CTA was performed using Helical CT in sixty three cases of acute subarachnoid hemorrhage Results Twenty four patients with intracranial aneurysms were found by CTA, one case of aneurysm was found by DSA. Diagnostic results were confirmed by operation. Conclusion CTA is a rapid?safe and accurate method in the diagnosis of intracranial aneurysms, particularly for acute and severe patients.

SUMMARY Peripheral T cell lymphomas-unspecified(PTCL-U) is an uncommon malignant tumor, accounting for 5%-7% of non-Hodgkin’s lymphoma. Clinical feature of a case of PTCL-U was investigated and the optimal treatment protocol was proposed. The clinical presentation of this case was progressing limbs weakness with sudden paralysis. Multiple superficial lymph nodes swelling and decreased sensation in all modalities below T10 level were found in physical examination. Bilateral leg paralysis (Grade 0/5) with high muscle tension, overactive knee reflex, bilateral Babinski sign (+) were present. Magnetic resonance imaging(MRI) showed the mass, which was around spinal cord located in T6-T8 vertebra canal, with intense enhancement after the administration of gadolinium diethylenetriamine penta-acetic acid. Abnormal signal in multiple centrums and accessories could also be found in MRI scan. Initial diagnosis was lymphoma, multiple systems involved. Laminectomy and epidural tumor resection were performed immediately. The dural sac was narrowed obviously by surrounding tumor. The result of pathological examination was PTCL-U. After operation, the level of pain sensation was descent, and touch sensation recovered. The patient received chemotherapy and his muscle strength was partly recovered in 4 months. Early diagnosis of peripheral T cell lymphomas-unspecified was difficult and easily misdiagnosed with poor prognosis. A review of literature showed central nervous system lesions occurred in advanced stage. However, the report of representation of intraspinal mass as initial symptom like the case was rare. For acute paraplegia, laminectomy and tumor resection should be performed as soon as possible. Regular radiotherapy and chemotherapy should be considered after operation. However, the value of local chemotherapy need to be further investigated.

Objective:To explore the application and key points of microchannel approaches in resec-tion of cervical intraspinal tumors.Methods:A retrospective analysis was performed on 51 cases of cervi-cal spinal canal tumors from February 2017 to March 2020.Among them,5 cases were located epidural space,6 cases were located epidural and subdural space,and 40 cases were located under the subdural extramedullary space(6 cases were located on the ventral side of the spinal cord).The maximum diameter ranged from 0.5 to 3.0 cm.The clinical manifestations included neck,shoulder or upper limb pain 43 cases,sensory disturbance(numbness)in 22 cases,and limb weakness in 8 cases.The micro-channel keyhole technique was used to expose the tumor,and the tumor was resected microscopically.Results:In this study,35 patients underwent hemilaminectomy,12 patients underwent interlaminar fenestration,2 patients underwent medial 1/4 facetectomy on the basis of hemilaminectomy or interlaminar fenestration.Two tumors were resected through anatomy space(no bone was resected).The degree of tumor resection included total resection in 50 cases and subtotal resection in 1 case.The type of the tumor included 36 schwannomas,12 meningiomas,2 enterogenic cysts and 1 dermoid cyst.There was no infec-tion and cerebrospinal fluid leakage postoperatively.Limb numbness occurred in 7 patients.The average follow-up time was 15 months(3 to 36 months).No deformity such as cervical instability or kyphosis was found.The tumor had no recurrence.Conclusion:The cervical spinal canal is relatively wide,cervical tumors with no more than three segments can be fully exposed by means of microchannel technology.Besides intramedullary or malignant tumors,they can be microsurgically removed.Preservation of the skeletal muscle structure of cervical spine is beneficial to recover the anatomy and function of cervical spine.The electrophysiological monitoring helps to avoid spinal cord or nerve root injury.

OBJECTIVETo observe the efficacy differences between herb-partitioned moxibustion on navel and clomiphene for anovulatory infertility.

METHODSWith double-blind double-dummy randomized control method, a total of 40 patients with anovulatory infertility were randomly divided into a moxibustion group and a clomiphene group, 20 cases in each one. Blinding was conducted on both patients and doctors. The patients in the moxibustion group were treated with herb-partitioned moxibustion on navel and oral administration of clomiphene placebo, while the patients in the clomiphene group were treated with placebo-partitioned moxibustion on navel and oral administration of clomiphene. The herb-partitioned moxibustion and placebo-partitioned moxibustion were given at the end of menstruation, 1.5 hours per treatment, once a week, and no treatment was given during menstruation. The oral administration of clomiphene and clomiphene placebo were given from 5 days into menstruation, 50 mg, once a day, for consecutive 5 days. One menstrual cycle was taken as one treatment course, and 3 treatment courses were conducted. After 3 treatment courses, the endometrial thickness (ET), maximum follicular diameter (MFD), ovulation rate (OR) and effective rate (ER) were evaluated between the two groups.

RESULTS(1) Compared before treatment, ET was significantly increased after treatment in the two groups (both<0.05); after treatment, the ET in the moxibustion group was higher than that in the clomiphene group (<0.05). (2) After treatment, MFD was significantly increased in the moxibustion group (<0.05) and insignificantly increased in the clomiphene group (>0.05); the MFD in the moxibustion group was higher than that in the clomiphene group (<0.05). (3) The OR was 75.0% (15/20) and 65.0% (13/20) in the two groups respectively, which were not significantly different (>0.05). (4) The total ER in the moxibustion group was 95.0% (19/20), which was superior to 70.0% (14/20) in the clomiphene group (<0.05).

CONCLUSIONSThe clinical efficacy of herb-partitioned moxibustion at navel on anovulatory infertility was superior to that of clomiphene, but their effects on OR was similar.
