Objective To observe the changes of systolic time interval after neonatal asphyxia and explore its relationship with clinical manifestation and prognosis. Methods Tow-dimensional and Doppler echocardiography were employed to detect tow - dimension parameters and left and right ventricular STI in 27 mild and 18 severe asphyxiated neonates as well as 14 normal controls and its relationship with clinical manifestation and prognosis was analyzed. Results There was no difference in cavity and thickness of heart and great arteries between normal and asphyxiated neonates. In acute stage mild and severe asphyxiated neonates had a shorter right ventricular ejection time (RVET) than normal neonates and a longer right ventricular prejection period (RPEP) was found in severe neonates than that in normal and mild asphyxiated neonates. Left ventricular preejection time (LPEP) was prolonged in comparison with normal neonates in acute stage and convalescence. There were more cases with increased RPEP/RVET in severe asphyxiaed group than those in mild and normal group in acute stage. The incidence of heart failure in acute stage and disability in late period was higher in cases with increased RPEP/RVET than that with normal RPEP/RVET. Conclusion Asphyxia has more severe damage to right ventricle than that to left ventricle. Cases with increased RPEP/RVET are prone to suffering from heart failure in acute stage and more likely to undergo disability in late period.

Objective To study of the imaging diagnosis and differential diagnosis of cystitis glandularis. Methods The clinical data and imaging findings of 8 cases with cystitis glandularis proved by pathology were retrospectively analyzed with literaures re-view. Results The lesions on images appeared as nodular mass in 4 cases, diffuse in 2 cases and mixed type in 2 cases,1 case with cystic degeneration. The lesions in 2 cases obviously reduced in size after treatment. The CT value of the lesions post contrast-en-hanced scan averagely increased up to 15.8 HU compared with that of plain scan. The lesions were localized in 6 cases and diffuse in 2 cases. Conclusion cystitis galandularis has some imaging characteristics, but the final diagnosis is depended on pathology.

Objective To explore the diagnostic value of axial diffusion tensor imaging(DTI) for gliomas grading at 3 .0T MRI , analyze the characteristics of different grades gliomas of axial DTI in order to improve diagnostic accuracy .Methods A retrospec‐tive analysis was performed involving a group of 37 cases of high grade glioma and 26 cases of low grade glioma confirmed by the pathological results in affiliated hospital of Luzhou medical college ,observation analysis was obtained in axial DTI ,peritumoral neu‐rofibrillary was divided into three types :displacement ,interruption and neurofibrillary tangles(NFT) .Results among the 26 cases of low grade glioma ,there were 18 cases of displacement ;8 cases of interruption ,no NFT ;among the 37 cases of high grade glio‐mas ,there were 9 cases of displacement ,21 cases of interruption ,and 7 cases of NFT (1 case of frontal lobe ,6 cases of temporal lobe);ordinal variables rank sum test in two independent samples between high grade glioma group and low grade glioma showed significant differences(Z= -3 .756 ,P<0 .05);χ2 test showed no significant difference(P>0 .05) ,frontal lobe appeared NFT in 1 case ,accounting for 2 .7% (1/37) ,temporal lobe appeared NFT in 6 cases ,accounting for 16 .2% (6/37) .Conclusion Peritumoral neurofibrillary of the low grade gliomas more performed displacement ,the high grade gliomas show more interrupts and NFT at 3 .0T MRI ,NFT in high grade gliomas is often seen in the temporal and frontal lobe .

Silent information regulator protein 1 (SlRT1) is one of the sirtuins and belongs to histone deacetyase. lts activity depends on nicotinamide adenine dinucleotide ( NAD+) and is regulated by NAD+. Experimental and clinical studies have shown the neuro-protective effect of SlRT1 in the pathogenesis of age-related eye diseases. ln this review, the relationship between SlRT1 activator and apoptosis in the retinal cells were discussed. The review also points to SlRT1 as a potential therapeutic target for the clinical management of age-related retinal disease.

s:The partical coding sequence of E2 gene of 13 Hog Cholera Virus(HCV) field isolates, Shimen strain, Chinese vaccine strain(C strain) and Thiverval strain attenuated by low temperature in France,were obtained by reverse trancriptase -polymerse chain reation (RT-PCR) and sequenced.All size were 251bp.The obtained 224bp sequences were analysed by DNA star and compared with the previously published sequences of Alfort strain ,Brescia strain and other references strains.The results showed that those sequencing fragments of 13 HCV field strains were the sequence of E2 gene of HCV.Compared with Shimen strain,the base substitute of all stains were randomly distributed in the entire sequence,and had not base insert and base gap.The variation most occurred at 3' end. The identity of nucleotide sequence and amino acid sequenceof 22 HCV strains were 78.1%～100%?78.4%～100%. The identity of nucleotide sequence and amino acid sequence of 13 HCV field strains were 78.1%～100%?78.4%～100%.The identity of nucleotide sequence and amino acid sequence of 4 HCV field strains isolated in the 1970s～1980s were 79.0%～88.3%?81.1%～87.8%.The identity of nucleotide sequence and amino acid sequence of 9 HCV field strains isolated in the 1990s were 80.8%～100%?83.8%～100% respectively. This paper showed that the genetic variation of HCV was diversity.

Objective To analyze the clinical features of pandrug-resistant Acinetobacter baumannii (PDR-Ab) in a hospital and compare the efficacy of different antibiotic treatments on patients with pneumonia caused by PDR-Ab.Methods Data were ret- rospectively collected from all isolated PDR-Ab strains in our hospital from February 2004 to March 2005.The clinical features and outcomes were reviewed.Results A total of 77 strains of PDR-Ab were collected, 45 of which were pathogens causing clini- cal infections (35 strains from lower respiratory tract, 6 from bloodstream, 3 from drainage fluid, and 1 from wounds).Lower respiratory tract was the most common source of PDR-Ab.More than 90% of the isolated PDR-Ab strains produced OXA-23 type?-lactamase.Cefoperazone-sulbactam plus minocyeline showed good efficacy for patients with PDR-Ab pneumonia.The total clinical cure rate was 68.4%.Bacterial eradication rate was 42.1%.The factors influencing bacterial clearance were pro- longed mechanical ventilation prior to positive culture (17.5 d vs 5.5 d).mixed infection (100% vs 12.5%) and lower GCS score (9.1?0.7 vs 13.2?2.1).Concomitant septic shock (OR=13.8) and APACHEⅡscore (OR=2.1) were independent factors of clinical outcome.Conclusions Nosocomial infections caused by PDR-Ab are not untreatable.Our analysis suggests that cefoperazone-sulbactam plus minocycline may be an effective treatment for lower respiratory tract infections caused by PDR-Ab in our hospital.

Objective:The immunological effects of HCV-DNA vaccine with different adjuvants were detected by ELISPOT in mice.Methods:Female BALB/c mice were primed with naked HCV-DNA, HCV-DNA encapsulated by liposome DDAB/EPC or DC-Chol/DOPE, HCV-DNA mixed with Montanide ISA 720 or aluminum hydroxide, respectively, and boosted twice accordingly in a four-week interval. Cytokine production by splenocytes was assessed by ELISPOT.Results:In most cases, splenocytes from mice vaccinated with DDAB/EPC liposome produced more IFN-?. These splenocytes also have significant higher IL-2 production compared with the other groups. In expansion with NS5b, splenocytes from alum group have significance in IL-4 production compared with other groups. The profile of cytokine production revealed that the INF-? overwhelmed IL-4 in naked DNA, DDAB/EPC, and DC-Chol/DOPE groups while IL-4 surmounted IFN-? in alum and Montanide groups.Conclusion:Encapsulation with liposome DDAB/EPC has the strongest adjuvant effect in inducing Th1 dominated immunity. Alum and Montanide can convert the Th1 nature of DNA vaccine to Th2-biased immunity.
