Objective To explore the effectiveness and significance of neuronavigation in transsphenoidal approach microneurosurgical treatment of pituitary adenoma.Methods A total of 12 patients with pituitary adenomas underwent transsphenoidal surgery.Before the surgery a continuous CT or MRI scanning was adopted,and then the data were inputted into the neuronavigation system for 3-D reconstruction and registration.During the surgery,real-time positioning of the anatomic midline,the anterior wall of the sphenoidal sinus,and the floor of the sella turcica was employed by using the neuronavigation system,as well as the identification of the cavernous sinus and the internal carotid artery to avoid unexpected injury.The extent of tumor resection was assessed postoperatively.Results The mean fiducial error was 2.13?0.94 mm,and the accuracy of targets was

Aim To investigate changes of MAP2 expression level in rat hippocampal pyramidal cells induced by chronic stress, and to explore effects of tianeptine on them. Methods 25 rats were divided randomly into three groups:Control group,Stress group and Stree-tianeptine group. The forced-swimming was performed to rats in stress group and stress-tianeptine. Using the immunohistochemistry and the computerized image technique, expression levels of phosphorated MAP2 and the number the Positive cells were assayed quantitatively in each group. Results Compared with control group (149.34?1.81), the phosphorated MAP2 average gray degree in pyramidal cells of stress group (144.99?4.40) was significantly lower, that of the stress-tianeptine group (148.84?2.73) was significantly higher than that of stress group; The number of phosphorated MAP2 positive cells in stress group (40.36?1.35) was significantly less compared withthat of control group (42.73?1.56); that of stress-tianeptine group (42.14?1.62) was significantly more than that of stress group. Conclusion It is suggested that tianeptine could inhibit the enhancement of phosphorated MAP2 expression in hippocampal pyramidal cells induced by chronic stress.

Objective To compare epididymis-sparing orchiectomy (group A) with traditional orchiectomy (group B ) in patients with advanced prostate cancer,and to evaluate which procedure is better.Methods A total of 60 cases of advanced prostate cancer patients were enrolled,with 30 cases in group A and 30 cases in group B.They were given oral anti-androgen from 1 day after castration.Serum level of testosterone and prostatic specific antigen (PSA) was detected before castration,and 1 week,1,3,6,9 and 12 months after castration.Patient satisfaction was also evaluated.Results On time point of 12 months after castration,the average level of serum testosterone was 0.2 nmol/L (95 ％ confidence interval,0.1 ～ 0.9 nmol/L) in group A and 0.3 nmol/L (95％ confidence interval,0.2 ～ 0.9 nmol/L) in group B (P ＞0.05 ) ; the average value of PSA was 0.22 ng/ml in group A and 0.27 ng/ml in group B (P ＞0.05 ) ; patient satisfaction rate was 96.7％ (29/30) in group A and 53.3％ (16/30) in group B.Conclusions No significant difference of testosterone level and PSA is found between the 2 groups.However,epididymis-sparing orchiectomy meets the psychological needs better because it helps to maintain the appearance of the scrotum through epididymis preservation and epididymoplasty.

OBJECTIVETo investigate the microsurgical tchniques and effects for the resection of anterior clinoid meningioma (ACM).

METHODSBetween January 2003 and March 2013, a total of 46 ACM patients were operated on via the pterion approach or lateral subfrontal approach. There were 16 male patients and 30 female patients, their mean age was 48.5 (16-69) years. Symptoms lasted from 1 month to 9 years(average 24.7 months). Preoperative CT and MRI examination showed that the tumors were located in the anterior clinoid process (25 cases on the right side, 21 cases on the left side). The average maximal tumor diameter was 4.4 cm (1.9-7.4 cm). The patients were peroidly followed-up on outpatient on 3 months to 6 months, then every year postoperativelly. The clinical data, radiological findings, surgical records and outcome of patients were retrospectively analyzed, and the prognostic factors were ananlyzed by using of the unpaired data χ(2) test with continuity correction.

RESULTSOf fourty-six patients operated on, apparently complete removal was achieved in 36 patients (78.3%), 10 patients (21.7%) had minimal residual tumors, 5 of which had gamma knife radiosurgery. Preexisting visual deficit improved in 21 of 41 patients (51.2%), unchanged in 16(35.6%), and worsened in 9(20.0%). At 3-6 months after discharge, 37(80.4%) patients had a good recovery, 7(15.6%) patients were moderately disabled, 1(2.2%) presented with severe disability, and 1 (2.2%) patient died of surgery-related causes. The tumor wrapping blood vessels (χ(2) = 4.676, P = 0.031) and violating cavernous sinus(χ(2) = 4.973, P = 0.026) were causes of unfavorable prognosis. During the mean follow-up of 35.1 months (range, 4-107 months) for 40 patients, the average Karnofsky score was 83.2. Tumor recurred in 4 cases: 2 of which required reoperation, and 2 had gamma knife radiosurgery.

CONCLUSIONSTumor wrapped vessels and invasion of the cavernous sinus are important unfavorable prognostic factors for ACM resection. By using appropriate surgical strategies and techniques, ACM can be removed safely via the pterion approach or lateral subfrontal approach with relatively low morbidity and mortality.

GI (GIGANTEA) is one of the output key genes for circadian clock in the plant. The JrGI gene was cloned and its expression in different tissues was analyzed to facilitate the functional research of JrGI. RT-PCR (reverse transcription-polymerase chain reaction) was used to clone JrGI gene in present study. This gene was then analyzed by bioinformatics, subcellular localization and gene expression. The coding sequence (CDS) full length of JrGI gene was 3 516 bp, encoding 1 171 amino acids with a molecular mass of 128.60 kDa and a theoretical isoelectric point of 6.13. It was a hydrophilic protein. Phylogenetic analysis showed that JrGI of 'Xinxin 2' was highly homologous to GI of Populus euphratica. The result of subcellular localization showed that JrGI protein was located in nucleus. The JrGI, JrCO and JrFT genes in female flower buds undifferentiated and early differentiated of 'Xinxin 2' were analyzed by RT-qPCR (real-time quantitative PCR). The results showed that the expression of JrGI, JrCO and JrFT genes were the highest on morphological differentiation, implying the temporal and special regulation of JrGI in the differential process of female flower buds of'Xinxin 2'. In addition, RT-qPCR analysis showed that JrGI gene was expressed in all tissues examined, whereas the expression level in leaves was the highest. It is suggested that JrGI gene plays a key role in the development of walnut leaves.
