Objective To investigate the clinical features of moyamoya disease in children and the prognosis of encephaloduroarteriosynangiosis ( EDAS) . Methods According to the age of first operated patients,317 children with moyamoya disease who received EDAS from January 2004 to December 2010 were divided into 3 groups:infant group (n=16,<3 years of age),preschool group (n=42,3 to 6 years of age),and adolescent group (n=259,6 to 17 years of age). The clinical data and the efficacy of operation of the patients were analyzed retrospectively. Results (1) Among the 3 groups of patients,the incidences of cerebral infarction in the infant group (81. 2%,13/16) or the preschool group (69. 0%,29/42) before procedure were significantly higher than the adolescent group (48. 3%,125/259). There were significant differences (χ2 =11. 741,P<0. 01). (2) Before surgical intervention,the infarct volume enlargement or the recurrence of infarction rate at different parts of brain in the infant group (62. 5%,10/16) was higher than that of the preschool group (31. 0%,13/42) and adolescent group (3. 9%,10/259). There was significant difference (χ2 =77. 437,P <0. 01). (3) The overall rate of favourable prognosis was 86. 4% (274/317). There were significant differences between the 3 groups (χ2 =9. 026,P<0.02). Conclusion The conditions of children with moyamoya disease progresses rapidly and their clinical prognosis is poor. It is safe and effective to perform EDAS early moyamoya disease in children.

Objective To determine whether Topiramate(TPM) has an effect on basic fibroblast growth factor(bFGF) expression in hippocampus in a chronic kindling rat model of epilepsy.Methods Chronic kindling rat models were established by pentetrazole(PTZ) and divided into three groups:PTZ group,TPM group and normal control group.Each group then divided into three subgroups according to different time point of kindling(5,10 and 15 d).The expressions of bFGF in CA1,CA3 and dentate gyrus areas of hippocampus were detected by immunohistochemistry method.The cellular morphologic changes were observed by HE staining method.Results(1) There was no difference of epileptic praxiology between PTZ and TPM groups.(2) Compared with normal control group,bFGF-positive cells in dentate gyrus in PTZ group and TPM group were increased significantly at each time point(all P

Objective To observe the changes of respiratory musc]e strength by traditional Chinese medicine combined with cholinesterase inhibitors in myasthenia gravis (MG) patients.Methods Thirty-four cholinesterase inhibitor-resistant patients,of them 14 were MG patients with stage Ⅰ ,and 20 were stage Ⅱ ,were treated with bromide dimethylcarbamate ( 360-480 mg/d ).Traditional Chinese potion were administered in those without effectiveness,and the dosages of bromide dimethylcarbamate decreased with Traditional Chinese potion lasting for 4-6 months.Vital capacity ( VC ),maximal voluntary ventilation ( MVV ),maximal inspiratory pressure ( PIM ),maximal expiratory pressure ( PEM ),respiratory centre driving pressure ( P0.1 ),residual volume ( RV )were measured before and after treatment.Results The amelioration of VC,MVV,PIM,PEM,P0.1 ,RV,respiratory muscle strength and other indicators of 34 MG patients were not obviously after treatment with cholinesterase inhibitor alone ( P ＞ 0.05 ).After treatment with traditional Chinese medicine combined with cholinesterase inhibitors,VC,MVV,PIM,PEM ( before treatment:76.66% ± 18.59%,68.03 % ± 10.45 %,43.25 % ± 18.16%,21.75 % ±14.44% ) increased significantly in all 34 MG patients( after treatment:86.91% ± 14.87% ,75.11% ± 11.17%,52.66% ±20.32% ,28.56% ± 10.06% ) ( P ＜ 0.05).RV decreased from 164.94% ± 67.97% to 143.16% ±79.21% (P ＜0.01 ),and respiratory muscle strength,endurance and other indicators significantly improved (P ＜0.01).PIM(65.80% ±28.03% to 52.66% ±20.32%),and PEM (37.03% ±20.57% to 28.56% ±10.06%)improved more significantly in group stage than in group stage (P ＜0.01 ).Respiratory muscle endurance in stage Ⅰpatients ( 108.71% ± 17.56% ) improved significantly than stage Ⅱ patients (96.01% ± 14.12% ,P ＜ 0.01 ).Conclusions Traditional Chinese medicine combined with cholinesterase inhibitors could effectively improve the lung function and respiratory muscle strength in patients with resistance of the cholinesterase inhibitors.The improvement of lung function,respiratory muscle strength were more obviously in stage Ⅰ patients than in stage Ⅱ patients.Respiratory muscle strength and endurance were improved greater in stage Ⅱ than in stage Ⅰ patients.

Streptococcus pneumoniae(S.pn) is an opportunity pathogenic bacteria,environmental factors play a key role in the pathogenicity of S.pn. It is important to study virulent gene in vivo. The S.pn suicide plasmid containing gfp reporter was constructed by fusing the genes pneumolysin and gfp,in which gfp is an excellent molecule probe in vivo. The plasmid was integrated to No.22 S.pn by homologous recombination. The recombinant S.pn was gained and evaluated in aspects of fluorescence excitation, biological character and physio-activity. The results showed it is efficient and available to report the expression of virulent genes in vivo and in vitro, which will provide a new easy method for evaluating and screening the virulent genes of S.pn in vivo.

ObjectiveTo explore effects of food viscosity and sex on hyoid motion during swallowing in normal elder.MethodsVideofluoroscopic studies were done in 60 healthy elder. Hyoid motion during swallowing food with different viscosity was measured.ResultsOlder male had longer movement duration, greater amplitudes of upward and forward movement than older female (P<0.05). Amplitudes of upward movement in jam thick swallow and bread thick swallow were greater than that in liquid swallow (P<0.01). Bread thick swallow had the longest movement duration; liquid swallow had shortest movement duration.ConclusionThe hyoid bone moves both upward and forward during swallowing, the amplitude of upward displacement is highly variable and influenced by food viscosity. The duration and amplitude of hyoid motion in male or female are different.

OBJECTIVETo investigate the factors influencing the pregnancy outcomes of artificial insemination with donor sperm (AID), improve the pregnancy rate, and evaluate the safety of the offspring.

METHODSWe retrospectively analyzed 7,761 cycles of AID for 5,109 infertile couples performed between July 1, 2005 and June 30, 2013 in the Center of Reproductive Medicine of Shenyang No 204 Hospital, the outcomes of pregnancy, and the incidence of birth defects.

RESULTSTotally, 2 252 clinical pregnancies were achieved by AID, in which the pregnancy rate per cycle was 29. 02% and the cumulative pregnancy rate was 44. 08%. The clinical pregnancy rate was remarkably higher in the females of ≤ 35 years than in those of > 35 years old (30.31% vs 20.18%, P < 0.01), in the women with < 5-year infertility than in those with > 5-year infertility (30.83% vs 28.16%, P < 0.01), and in the patients of the ovarian stimulation group than in those of the natural cycle group (33.22% vs 28.68%, P < 0.01) The clinical pregnancy rate was the highest in the first treatment cycle (29.87%), with statistically significant difference from the fourth cycle (23.61%) (P < 0.05), but not between the other cycles (P > 0.05). There were 28 cases of birth defects in the offspring (1.40%), including 6 cases (21.43%) involving the cardiovascular system, 4 (14.29%) involving the musculoskeletal system, 3 (10.71%) involving the urogenital system, 3 (10.71%) involving the central nervous system, 2 cases (7.14%) of cleft lip and palate, 2 (7.14%) involving the respiratory system, 2 (7.14%) involving the gastrointestinal digestive system, and other anomalies.

CONCLUSIONFemale age, infertility duration, and ovarian stimulation treatment are important factors influencing the clinical pregnancy rate of AID. Artificial insemination with cryopreserved donor sperm does not increase the incidence of birth defects, which is considered as a relatively safe technique of assisted reproduction.
