Objective To investigate the efficacy of foramen magnum decompression alone and foramen magnum decompression + Syrinx-shunt in the treatment of Chiari anomalies with syringomyelia.Methods Forty-nine Chiari anomalies with syringomyelia patients were selected,28 patients performed foramen magnum decompression alone (surgical method Ⅰ group),21 patients performed foramen magnum decompression + Syrinx-shunt (surgical method Ⅱ group).The treatment efficacy was evaluated by postoperative clinical effect and MRI review.Results In surgical method Ⅰ group,effective in 18 cases,invalid in 10 cases,the effective rate was 64.3％ (18/28).In surgical method Ⅱ group,effective in 19 cases,invalid in 2 cases,the effective rate was 90.5％(19/21).There was statistical difference (x2 =4.45,P =0.034).Conclusion Foramen magnum decompression + Syrinx-shunt is effective in the treatment of Chiari anomalies with syringomyelia,which is applicable for these patients and has a more precise consequence than foramen magnum decompression alone.

Objective To analyze the complications ofventriculoperitoneal shunt in the treatment of pediatric hydrocephalus,and improve operative method,in order to reduce postoperative complications and improve the clinical curative effect.Methods A total of 39 infants with hydrocephalus who underwent adjustable shunt were retrospectively analyzed,including surgical methods,results,and complications,and put forward counter measures.Results Thirty cases of postoperative clinical symptoms obviously improved compared with preoperative,head CT review were clearly seen with ventricle retraction.Nine cases suffered with complications after operation.Obstruction of shunt tube was found in 4 cases,shunt exposed in 3 cases,and postoperative infection in 2 cases.Conclusions Ventriculoperitoneal shunt complications related to surgery itself.Improved surgical techniques,and taking appropriate treatment measures can effectively reduce the incidence of complications.

BACKGROUNDBronchioloalveolar carcinoma is a kind of special lung cancer. The aim of this study is to analyze its characteristics, surgical intervention and prognosis.

METHODSFifty-eight surgically treated patients with bronchioloalveolar carcinoma from 1993 to 2000 were followed up. The clinical characteristics, surgical mode, site of recurrent disease and survival were analyzed.

RESULTSOut of 58 patients, 15 were male (25.9%), and 43 were female (74.1%). Fifty-one patients performed lobectomy ( 87.9%). The 1-, 3- and 5-year survival rate was 91.4%, 75.9% and 60.3% respectively. There was no remarkable difference in survival between chemotherapy group and non-chemotherapy group after surgery (P= 0.22).

CONCLUSIONSLobectomy is performed commonly in patients with bronchioloalveolar carcinoma. No obvious correlation is found between postoperative chemotherapy and survival.

Objective:To explore the relationship between ten‐eleven translocation 2 (TET2) Mutations and Expression of 5hmC in breast cancer .Methods :TET2 mutations in breast cancer tissues from 100 patients were detected by Sanger method . The expression of 5hmC in breast cancer tissues was detected by immunohistochemistry . The relationship between TET2 mutations and expression of 5hmC was analyzed .Results :A total of 13 kinds of TET2 mutations were identified in 100 patients .Among them ,3 new types of mutations were identified in 4 patients . They were Ala341Val , Leu1622Phe and Pro1578Tyr .Pro1578Tyr was identified in two patients .And immunohistochemical analysis showed that there was a sharp reduction of 5hmC in breast cancer tissues with TET2 mutations than in breast cancer tissues without TET2 mutations . Conclusions :T ET2 mutations can lead to decrease of 5hmC level in breast cancer .
