Objective: To investigate the immune response induced by Cysticercus cellulosae protective antigen cC1 DNA vaccine in mice and the protective immunity induced by immunized newborn pigs. Methods: Recombined plasmid p3 cC1 was constructed by inserting full length cC1 cDNA into an eukaryotic expression vector pcDNA3. Mice were injected intramuscularly with the recombined construct. Anti cC1 antibody and IgG 2a in serum were screened by ELISA. Then the protective immunization in pigs was done. Results: The immune response of specific antibody was induced during the 3r week. The highest level was during the 8th week. IgG 2a response was detected during the 2nd week. The higher duration of IgG 2a response induced by DNA vaccine was longlived. The protective rate induced in immunized newborn pigs was 73%. Conclusion: The cC1 DNA vaccine can effectively induce protective immunity in newborn pigs.

Objective To apply six sigma management method to optimizing flow,enhancing treatment quality,prolonging service life and decreasing purchase cost of the non-coated surgical instrument.Methods The treatment flow of the noncoated surgical instrument was optimized through five steps of six sigma method including defining,measuring,analyzing,improving and controlling.The treatment results before and after flow optimization were compared,analyzed and evaluated.Results The rates for corrosion and rejection were both decreased significantly after flow optimization,while the quality was increased obviously (P＜0.05).Conclusion Six sigma management method involved in the treatment of the non-coated surgical instrument saves purchase cost,enhances the efficiency of disinfection supply room and facilitates effective supervision and monitoring.

Objective To evaluate the efficacy and safety of topiramate(TPM) as add - on drug treating infants with severe epilepsy. Methods We performed prospective label add - on study in 12 infants (aged 4 to 19 months) with sever seizures of different types. TPM was add - on one or more other baseline drugs and the efficacy was evaluated according to seizure type and frequency Results TPM initiated in a daily dose of 0.5 - 1 0 mg/kg, followed by a 1 - 2 weeks titration on the increase of 0 5 - 1.0 mg/kg up to a maximum daily dose of 4 - 10 mg/kg. After a mean period of 6 2 months (range 3- 13 montks), Total efficacy was 75 % and 50 % were controlled completely. Seizure frequency was unchanged in 3 patients (25 % ). As for seizure type, TPM was more effective in complex partial as compared with generalized tonic-conic seizures. Mild adverse events were present in 3 patients (25 %), represented hypersonia, fever and decreased speech. Conclusions TPM may be a available drug in infants with severe epilepsy. It is safe, with mild adverse effect in fewer patients.JAppl Clin Pediatr,2004,19(11):986-987

Objective To analyze MRI manifestation of the neonatal purulent meningitis retrospectively,including conventional MRI and diffusion-weighted imaging (DWI),and to evaluate the value of MRI in early assessment of the neonatal purulent meningitis.Methods From Jul 2004 to Jul 2009,20 full-term newborns (14 male,6 female) from Shengjing hospital were included in this study,all of which were diagnosed as purulent meningitis.MRI and DWI examinations were performed within 72h after the diagnosis.Results (1) Among those 20 infants,19 infants (95%) had positive findings,including 7 cases of cerebral infarction,4 cases of subdural effusion,3 cases of encephalomalacia,1 case of hydrocephalus,1 case of ependymitis and 7 cases of intracranial hemorrhage.(2) Among the 7 cases of infarction,5 cases showed hypointensity on T1WI and hyperintensity on DWI and T2WI,but the other 2 cases only showed hyperintensity on DWI.Conclusion MRI can detect infarction and hemorrhage in the early stage of purulent meningitis.So MRI,especially DWI,is very important for the early diagnosis and evaluation of neonatal purulent meningitis.

OBJECTIVETo investigate the precise locations of the blood vessels and nerves surrounding the seminal vesicles (SV) in men and provide some anatomical evidence for SV-related minimally invasive surgery.

METHODSWe observed the courses and distribution of the blood vessels and nerves surrounding SVs and obtained the data for positioning the SV neuroplexes in 20 male pelvises.

RESULTSOne branch of the neuroplexes was distributed to the SVs bilaterally with the neurovascular bundles, (2.85 ± 0.18) cm from the median sulcus of the prostate (MSP), while another branch ran through the Denonvillier fascia behind the SV, (0.81 ± 0.06) cm from the MSP. The arterial SVs (ASV) originated from the inferior vesical artery and fell into 4 types, 55% going directly to the SVs as one branch, 15% running between the SV and the ampulla of the deferent duct as another branch, 25% downward as 2 branches to the SV and between the SV and the ampulla of the deferent duct respectively, and 5% as the other ASVs. The shortest distance from the ASV through the prostatic neuroplexus to the posterior SV was (1.08 ± 0.09) cm.

CONCLUSIONIn SV resection, neuroplexus injury can be reduced with a bilateral distance of < 2.85 cm and a posterior distance of < 0.81 cm from the MSP, and so can bleeding by vascular ligation between the SV and the ampulla of the deferent duct.

OBJECTIVETo study the pharmacologic action of Artemisia burning products.

METHODSThe extractions of Artemisia burning products were determined by spectrophotometry. The scavenging ability of Artemisia burning products on DPPH was evaluated. The chemical components and structures of Artemisia burning products were analyzed by Gas Chromatography and Mass Spectrometry (GC-MS).

RESULTSThe scavenging ability of extractions from Artemisia burning products was the strongest. Thirty-six chemical components were detected, and the 5-tert-Butylpyrogallol among them had a stronger anti-oxygen capacity, its scavenging free radical ability was 1.55 times and 1.21 times as strong as VitC and BHT, respectively.

CONCLUSIONThe scavenging free radical ability of 5-tert-Butylpyrogallol extracted from Artemisia burning products is stronger than the natural antioxidant of VitC and artificial synthetic of BHT.

A method for the determination of S-Adenosyl-L-methionine in fermentation liquid using the high performance liquid chromatography coupled with UV detector (HPLC-UV) was developed.A good linearity was obtained in the range of 0.1～1.0g/L (r = 0.9969) for S-Adenosyl-L-methionine.The average recoveries of S-Adenosyl-L-methionine were 99.89%～101.7% and the relative standard deviations were 0.48%～1.36%.The method is simple and rapid with reproducibility for the determination of S-Adenosyl-L-methionine in ferment liquid.

Objective To investigate the intervening effect of movable cupping on sub-health status. Methods Movable cupping was performed on bilateral bladder meridians and the Du meridian in 12 patients with sub-health status. The sub-health status rating scale score, the visual analogue pain intensity scale score, hemorheological parameters and immunoglobulins were observed before and after movable cupping.Results The sub-health status rating scale score, the visual analogue pain intensity scale score, whole blood viscosity 200 and plasma viscosity decreased after treatment compared with before in the patients, and there were statistically significant differences (P<0.05). Whole blood viscosity 1, whole blood viscosity 2 and whole blood viscosity 3 decreased and IgG, IgA and IgM increased after treatment compared with before in the patients, but there were no statistically significant differences (P>0.05). Conclusion Movable cupping has clinically a certain improving effect on bodily sub-health status.
