Objective To explore the influence of mother's treatment for syphilis on the incidence of congenital syphilis in newborn babies.Methods 40 cases of neonatal congenital syphilis,according to mother different treatment methods,were divided into regular treatment group (20 cases),mother without regular treatment group (10 cases),mother with no treatment group (10 cases).The incidence of neonatal congenital syphilis was compare.Results The neonatal congenital syphilis could affect multiple systems,manifested as skin damage,pathological jaundice,hepatosplenomegaly,edema,anemia,thrombocy to penia,bone injury,cerebrospinal fluid abnormalities et al.The incidence rate of neonatal congenital syphilis in regular treatment group was 10％,which was significantly lower than normal treatment 40％ and untreatment 50％ (x2 =11.2,P ＜ 0.05 ; x2 =20.4,P ＜ 0.01).The neonatal congenital syphilis incidence rate was not statistically significant between the informal group and untreatment group (x2 =0.68,P ＞ 0.05) ;30 cases were cured (75 ％),improved in 7 cases (17％) ;3 cases died (7 ％).Conclusion The prevention and treatment of syphilis infection in mothers are the key point to prevent neonatal congenital syphilis.

Objective To detect the expression of DNA repair enzyme O6-methylguanine DNA methyl-transferase(MGMT),cell proliferation-related nuclear protein(Ki-67)and P53 protein in gliomas,and inves-tigate the relationship and clinical significance among them and gloma grade. Methods 61 cases of brain glio-ma specimes and 16 cases of internal decompression of brain trauma were used to detect the expression of MGMT,Ki-67 and P53 by using immunohistochemical SP method. Results MGMT protein expression (19. 67%∶0,χ2 =3. 729,P=0. 062),Ki-67 protein expression(39. 34% ∶0,χ2 =5. 722,P=0. 016)and P53 protein expression(27. 87% ∶0,χ2 =9. 146,P=0. 002)showed significant differences in gliomas com-pared to normal brain tissues,the expression of Ki-67 was significantly higher in high-grade gliomas(Ⅲ-Ⅳ) than that in low-grade gliomas(Ⅰ-Ⅱ)(14 ∶10,χ2 =11. 718,P =0. 001). No significant difference was found between the MGMT and P53. Conclusion MGMT protein can be used as a biomarker in gliomas detec-tion;Ki-67 has a positive correlation with tumor grade,and can be used as a reference indicator of pathological grade;P53 protein expression may be used as a potential target for the treatment of gliomas.

Objective:To investigate the effect of Foxp3 on the invasion and metastasis of the ovarian cancer cells Skov 3 and the related mechanism.Methods: Plasmid overexpressing Foxp 3 gene was constructed and transfected into Skov 3 cells using liposome.Proliferation,invasion,RT-PCR and Western blot analysis were done to observe the expression of Foxp 3 gene in Skov3 cells and the invasion and metastasis ability.Also,MMP-2 and MMP-9 gene expression was detected.Results:Overexpression of Foxp3 was confirmed in Skov3 cells after Foxp3 plasmid transfection.Compared with the empty vector group , overexpression of Foxp3 gene significantly inhibited the migration and invasion of Skov 3 cells.Meanwhile , the expression level of MMP-2 and MMP-9 genes were decreased.Conclusion:Upregulation of FoxP3 gene expression can inhibit cell proliferation ,invasion and migration in ovarian cancer Skov3 cells through downregulating MMP-2 and MMP-9 gene expression.This study provided experimental basis for further research on Foxp3 gene and gene therapy for ovarian cancer.

Objective To investigate antibiotic resistance of Klebsiella pneumoniae and Escherichia coli in old patients with lower respiratory tract infections. Methods Kirby Bauer agar diffusion method was used to evaluate the drug sensitivity in 240 strains of Klebsiella pneumoniae and Escherichia coli isolated from patients with lower respiratory tract infection. Phenotypic confirmatory test recommended by NCCLS1999 was used to detect extended spectrum beta lactamases(ESBLs). Results The resistant rates of Klebsiella pneumoniae and Escherichia coli to 14 antibiotics in old patients and in non old patients with lower respiratory tract infections were amoxicillin 93 2% vs 87 3%, piperacillin 57 1% and 42 9%, cefuroxime 51 4% and 33 3%, cefotaxime 40 1% and 17 5%, ceftazidime 13 6% and 3 2%, ceftriaxone 39 0% and 17 5%, cefoperazone 37 3% and 15 9%, cefepime 10 2% and 3 2%, amikacin 47 5% and 34 9%, ciprofloxacin 54 2% and 38 1%, imipenem 0, cefoperazone/sulbactam 0, piperacillin/tazobactam 1 1% vs 0, and cefmetazole 9 6% and 4 8% respectively. Out of 240 clinical strains of Klebsiella pneumoniae and Escherichia coli, 78(32 5%) were considered ESBLs producers by phenotypic confirmatory test. The prevalence of ESBLs in old patients was 38 4%, which was much higher than that in non old patients(15 9%). The resistant rate of ESBLs producing strains to imipinem, cefoperazone/sulbactam, piperacillin/tazobactam and cefmetazole was the lowest, being 0, 0, 2 6% and 12 8%. Conclusions The resistant rates of Klebsiella pneumoniae and Escherichia coli to most antibiotics and the prevalence of ESBLs in old patients with lower respiratory tract infection were higher than that in non old patients. Imipinem, cefoperazone/sulbactam, piperacillin/tazobactam and cefmetazole were the effective antibiotics to infections caused by ESBLs producing strains.

Objective To explore the character of the myelodysplastic syndrome(MDS) with autoimmune disorders (AID).Methods The clinical data of 60 MDS patients were reviewed.Results 5 of 60 MDS patients had AID ,of which 3 had Graves' disease.The commonest MDS was refractory anemia with ringed sideroblasts (RAS).Conclusion MDS might occur with Graves' disease.Humoral immunological abnormality might play an important role in MDS patients with autoimmune disorders and FAB types might not be associated with this.

OBJECTIVE:To monitor the antimicrobial resistance of Enterococcus faecalis and Enterococcus faecium in our hospital from 2006 to 2008 in order to provide reference for clinical rational use of antibiotics.METHODS:The susceptibility of isolated enterococci was determined by K-B paper diffusion method,and the antibiotic resistance rates of Enterococcus faecalis and Enterococcus Faecium were analyzed using Whonet 5 software.RESULTS:Vancomycin was the most sensitive antimicrobial against Enterococcus faecalis and Enterococcus faecium.E.faecalis had low resistance rates to penicillin G,high concentration gentamicin,ciprofloxacin and rifampicin,while E.faecium had low resistance rates to high concentration streptomycin,tertracycline,chloromycetin,and qinupristin/dalforpristin.CONCLUSION:E.faecalis and E.faecium are multi-drug resistant.Antimicrobials should be used rationally based on the susceptibility test of E.faecalis and E.faecium.

A modified rapid microprocedure for the determination of VE in serum, was described. VE reduced Fe3+ to Fe2+ and then the Fe2+ combined with bathophenanthroline to form a pink complex -which could be determined spect-rophotometrically. As little as 0.3ml (or 0.2ml) of serum or plasma sample was sufficient for determination. The reproducibility of this method was good. The CV was 4.1% (n=15). The recoveries of added VE (0.8, 0.2 and 1.6 mg/dl) were 86.3-102.5%. The mean value and SD of 99 normal adults were 1.15+ 0.31mg/dl. This spectrophotometric method was simple and could be used in common, laboratories. Some affecting frctors were discussed.

Objective To learn the domestic investigation into pulmonary cryptococcosis in the 22 years.Methods We retrieved the literature about pulmonary cryptococcosis included in CMCC,and summarized the clinical data of 67 patients suffering from pulmonary cryptococcosis.Results The clinical situation and radiological manifestation of pulmonary cryptococcosis were diverse and nonspecific.Cryptococcal meningitis was the commonest complication(31.34%).Almost all patients with pulmonary cryptococcosis were once misdiagnosed.Final diagnosis mainly depended on the smear,culture or pathological examination of various clinical specimens.Therapeutic tool involved resection with operation and the application of anti-fungi drugs.Conclusion To increase the cognition to the disease is the key to increase the final diagnosis rate.Therapeutical effect of anti-fungi drugs should be emphasized,especially the application in preoperation and postoperation can decrease the dissemination of cryptococcus after operation,which might result in cryptococcal meningitis.
