Objective To study the significance of trans-sphenoid approach microsurgery in the management of pituitary adenomas. Methods Clinical data of 22 cases of pituitary adenomas treated by trans-sphenoid approach microsurgery in this hospital from January 1990 to December 2001 were analyzed retrospectively. Results The total resection rate was 68.2% (15/22). Follow- up in 17 cases for 1～13 years showed that different degree of improvement was achieved in the 12 cases of impairment in vision or visual field,but no recovery was obtained in the 5 cases of blindness. Conclusions Trans-sphenoid approach microsurgery is a minimally invasive, safe and effective method for the treatment of pituitary adenomas.

OBJECTIVETo summarize the clinical features of those Duchenne and Becker muscular dystrophy (DMD and BMD) patients who are complicated with epilepsy, and try to analyze the genotype- phenotype correlation.

METHODBy a retrospective analysis of 307 patients with DMD and BMD who attended Peking University First Hospital from February 2006 to September 2014,7 patients complicated with epilepsy were identified and their clinical data were collected. The possible mechanism of epilepsy in DMD and BMD patients was proposed after analyzing the genotype-phenotype correlation.

RESULT(1) Among 307 DMD and BMD patients, 7 cases had epilepsy, the prevalence was 2. 28%. (2) The age of onset of epilepsy ranged from 8 months to 11 years. Focal seizure was the most common seizure type (6 cases) , while other seizure types were also involved, such as generalized tonic-clonic seizure. As to epilepsy syndromes, 1 boy was diagnosed as benign childhood epilepsy with centrotemporal spikes (BECT). Six patients were treated with 1 or 2 types of antiepileptic drugs and seizures were controlled well. On follow-up, 6 of the 7 children had normal mental development, while the remaining 1 patient was diagnosed as mild mental retardation. (3) DMD gene mutations of all 7 patients were analyzed. Exons deletions were found in 6 cases while point mutation was found in 1 case.

CONCLUSIONThe prevalence of epilepsy in DMD and BMD patients was higher than the prevalence in normal population. The age of onset of epilepsy varies, and focal seizure may be the most common seizure type. Some patients may also present as some kind of epilepsy syndrome, such as BECT. In most patients, seizures can be controlled well by 1 or 2 types of antiepiletic drugs. No clear correlation was found between genotype and phenotype in DMD and BMD patients who were complicated with epilepsy, probably due to limited number of cases.

Objective To observe the effect of excretory/secretory products from Trichinella spiralis adult worms(AES)on cecal ligation and puncture(CLP)?induced sepsis in mice. Methods Forty?eight BALB/c mice were randomly divided into 3 groups:a sham operation group(PBS+sham group,Group A),a CLP?induced sepsis group(PBS+CLP group,Group B)and an AES treatment group(AES+ CLP group,Group C). The mice of each group were intraperitoneally injected with 25 μg of AES or PBS only as a control in a total volume of 200μl. Eight mice from each group were selected randomly for survival analy?sis of 96 hours. The other 8 mice in each group were observed for pathological changes in the lung,liver and kidney tissues by HE staining 12 h after CLP,and then determined for the detection of cytokines including TNF?α,IL?1β,IL?6,IL?10 and TGF? βin the sera by ELISA. Results The difference among the survival rates of mice in the 3 groups was statistically significant (χ2=21.16,P<0.05). Compared to Group A(100%),the survival rate of mice in Group B(0)decreased significantly(P<0.05),and also the pathological damage degrees in the lung,liver and kidney tissues of the mice in Group B increased signifi?cantly after CLP. Compared with the mice in group B,the survival rate of those in Group C(70%)increased significantly(P<0.05),and the pathological damage degrees in the lung,liver and kidney tissues of the mice in Group C decreased significantly after the treatment with AES. The differences among the levels of pro?inflammatory cytokines TNF?α(F=27.11,P<0.05),IL?1β(F=18.75,P<0.05)and IL?6(F=100.93,P<0.05)in the sera of the mice in the three groups were statistically signifi?cant. Compared with the mice in Group A,the levels of the 3 cytokines of those in Group B increased significantly(all P <0.05). However,after the treatment with AES,the levels of the pro?inflammatory cytokines of those in Group C decreased signifi?cantly(all P<0.05). The differences among the levels of immunoregulatory cytokines IL?10(F=10.88,P<0.05)and TGF?β(F=11.37,P<0.05)in the sera of the mice in the three groups were also statistically significant. Compared with the mice in Group B,the levels of IL?10 and TGF?β of those in Group C were higher after treatment with AES(both P<0.05). Conclu?sion T. spiralis AES has a therapeutic potential for alleviating sepsis induced by CLP in mice.
