Objective To investigate the PCR-based evaluation of prednisolone-induced relapse of asymptomatic Toxoplasma gondii infection and the therapeutic efficacy of azithromycin.Methods A total of 36 of female ICR mice,about 20 g,were randomly divided into 6 groups:contrast group (C),prednisolone group (P),infection group(I),infection plus prednisolone group (IP),infection plus azithromycin group(IA),infection plus prednisolone and azithromycin group (IPA).The infection group (I),infection plus prednisolone group(IP),infection plus azithromycin group(IA),infection plus prednisolone and azithromycin group (IPA)were challenged at week 0 with 10 cysts of Toxoplasma gondii Prugniaud strain per injection intraperitoneally.The prcdnisolone group (P),infection plus prednisolone group (IP) infection plus prednisolone and azithromycin group (IPA)were injectied with prednisolone 1 mg into hind medial subcutaneous every day from the 6th week to 7th week.The infection plus azithromycin group(IA),infection plus prednisolone and azithromycin group (IPA) were injectied with azithromycin 250 mg/kg intraperitoneally every day from the 6th week to 7th week.The serum samples were collected and DNAs extracted at week 0,1,2,3,4,5,6 and 7 for amplification of Toxoplasma gondii of specific B1 gene by PCR.All the mice were sacrificed 7 weeks after the challenge to calculate the number of cysts in brain tissues.Results Compared with the primer of AF146527 gene,the primer of B1 gene was more sensitive and specific.The method of PCR could amplify the productions of specific B1 gene Toxoplasma gondii 5 weeks before the challenge,while it could not amplified 5 weeks after the challenge.All the mice of the IP group were dead 2 weeks after the injection of prednisolone (week 7),and the only two mice of the IPA group were dead at the same time (P <0.05),respectively.Compared with the I group,IA group and IPZ group,the number of cysts in brain tissues of the IP group significantly increased (P <0.01).Conclusions B1 as target gene is more suitable for diagnosis of Toxoplasma gondii infection by PCR.Prednisolone could induce the relapse of asymptomatic Toxoplasma gondii infection of mice and the mice are finally dead.Azithromycin is effective but it can not completely cure the Toxoplasma gondii infection.

AIM: To study effect of endogenous carbon monoxide on intracellular calcium concentration and explore the mechanism in brain protection of endogenous CO in focal cerebral ischemia in rats. METHODS: SD rats were divided into three groups randomly, which including hemin, ZnPP group and saline group as control. Respectively saline, hemin, ZnPP were injected intra-peritoneally twelve hours before middle cerebral artery was occluded. Twenty four hours after MCAO model was set up, the concentration of carbon monoxide in blood and intracellular calcium in neural cells was examined. RESULTS: Contrast to saline group, the concentration of CO in blood rose up while intracellular calcium in occluded side decreased in hemin group; the concentration of CO in blood went down while intracellular calcium in occluded side rose up in ZnPP group, there was significant difference among them (P0.05). CONCLUSIONS: It may be one of mechanisms on brain protection in ischemic cerebral tissue that carbon monoxide affected intracellular calcium concentration of neural cells by regulating Ca~(2+)-K~+ channel on cell membrane as a messenger gaseous molecular and neurotransmitter.

Objective To investigate the correlation between executive function(EF) and characteristic of symptom in children with Tourette′s syndrome(TS).Methods EF were measured with Wisconsin Card Sorting Test(WCST) in 53 patients with TS,and symptom characteristics were evaluated with Achenbach Child Behavior Checklist(CBCL) and Yale Global Tic Severity Scale(YGTSS).Results Compared with healthy control,TS had poor executive performances significantly in WCST(all P

AIM: To establish a method for determination of astragloside Ⅳ in Danqi Injection (Radix Salviae Miltiorrhizae,Radix Astragali). METHODS:HPLC-ELSD with Hypersil C_(18) column was used.The mobile phase was composed of acetonitrile-water(38∶62).The flow rate was 0.85 mL?min~(-1).An evaporative light-scattering detector(ELSD) model 2000 was used as detector. RESULTS:For astragloside Ⅳ,the linear range was 1.074-(3.408 ?g),and the average recovery was 100.71%,RSD was 1.79%. CONCLUSION:The method is simple,accurate,reproducible and can be applied to the quality control of the preparation. anqi

Objective To design a kind of bed board that is suitable for various medical image diagnostic equipments. It is used to make the body position of the person who is examined to be fixed and can be moved with whom. Methods The bed board is made of low density plastics; its structure is similar to "winnowing fan" in shape. In which, the pipes filled with "multifunction developer" are arranged in order. The negative pressure vacuum bag and belts for the body positioning are installed on the bed board. Volumetric reconstruction has been done with single mode images, then multi- mode images volumetric fusion depend on registration with coronal and arrowy mark of image pipeline in volumetric reconstruction. Results The bed board can not be showed in CT, MRI, PET and SPECT with the soft tissue window, but the pipes be used as the marker for image fusion is displayed clearly. The body position is all the same with each medical image examination. National patent of the product was declared. Conclusion With the designed bed board, the multimode image fusion is rapid, simple and accurate, is easily expansion and popularize.

OBJECTIVE: To discuss the evaluation of comprehensive benefit of hospital pharmacy department with comprehensive index method. METHODS: Suitable evaluation indexes on social effects and economic returns were respectively selected to be assigned with weight numbers by analytic hierarchy process, and the comprehensive benefits of pharmacy department in our hospital during the period from 2002 to 2004 were evaluated. RESULTS: The index values of social effects, economic returns and comprehensive benefits increased year by year, which was in line with the objective actuality. CONCLUSION: It is feasible to evaluate comprehensive benefit of hospital pharmacy department with comprehensive index method.

Objective To investigated the clinicopathological findings and prognosis of 60 patients with pleomorphic carcinoma.Methods 60 cases of pleomorphic pulmonary carcinoma were collected and studied clinicopathologically between 1999 and 2011.All patients underwent pulmonary resections.Results There was no in-hospital death.1 had haemothorax that required reoperation,1 patient had a late cicatricial bronchial stenosis after sleeve lobectomy of the upper right lobe,and treated successfully by the resection of the right two lobes.The 3,5-year survival rates of all patients were 47.2％ and 25.6％ respectively.For N0 and N1-N2 patients,3-,5-year survival rates were 57.3％,32.5 ％ and 25.4％,17.1％,respectively.Overall survivals were of significant difference between radical resection and uncomplete resection.Multivariate Cox regression analyses of overall survival of all 60 patients indicated that radical resection (P =0.041) and nodal status (P =0.029) were significant independent prognostic factors.Conclusion Pleomorphic carcinoma is a rare type of lung cancer.Pleomorphic carcinoma of the lung was often found as a large mass peripherally located and was associated with poor prognosis.Radical resection and nodal status were significant independent prognostic factors.

ObjectiveTo investigate the effects of sevoflurane on short-term memory impairment and the relative synaptic mechanism.MethodsAt 12 h,24 h and 72 h after the mice were exposed to 1.5％ sevoflurane for 1h,the spontaneous alternation and locomotor activity was assessed by Y maze,the short term potentiation (STP) were measured with extracellular recording technique in hippocampal slices.ResultsAt 12h after administration with sevoflurane in vivo,the spontaneous alternation ( (54.7 ± 1.7) ％,P＜0.01 ) and locomotor activity (16.4 ± 1.3,P ＜ 0.01 ) decreased significantly compared with that of control group,and the population spike amplitude after induction of STP ( ( 122.3 ± 13.9) ％,P ＜ 0.05 ) decreased significantly in hippocampal slices,but there was no different at 24h and 72h.After administration with sevoflurane in vitro,the basic ( ( 83.5 ± 8.9) ％,P ＜ 0.01 ) or titanic ( ( 116.5 ± 14.9) ％,P ＜ 0.01 ) population spike amplitude decreased significantly in hippocampal slices,but the amplitude could recovery after wash-out.ConclusionSevoflurane can impair the shortterm memory by suppressing synaptic transmission in the near future but not the long future.
