Objective To investigate the function of metalloproteinase 2 (MMP 2) and tissue inhibitor of metalloproteinase 2 (TIMP 2) in neonatal acute lung injury(ALI) caused by LPS in rats. Methods Eighty eight newborn rats of 7 days were randomly divided into eight groups: control, 0.5 h, 1 h, 2 h, 4 h, 8 h, 16 h, 24 h after LPS was injected. The changes of lung pathology in newborn rats were observed and the changes of MMP 2 and TIMP 2 expression were measured by immunohistochemistry and RT PCR. Results Pulmonary hemorrhage was seen in newborn rats caused by LPS. The expression of MMP 2 mRNA and protein were 0.523?0.030 and 126.20?17.98; The expression of MMP 2 mRNA increased and the highest level was at 4 h(0.826?0.567, t=3.77, P

Objective To study the level of immunoglobulin and the prevalence of ANA in patients with Graves' diseases(GD).To explore the correlation between GD and other systemic autoimmune disorders.Methods Data of 145 patients with GD and 45 healthy subjects were collected.All cases were detected on the presence of ANA and the level of immunoglobulin,FT3,FT4,and thyroid specific antibodies.Results The presencerate of ANA and the level of IgG in patients with GD were higher than that in healthy controls [(28.28% vs 4.55%);(70.96?26.14 vs 60.41?11.01) mmol/L](P

Objective: To report our prelimilary experience of laparoscopic radical prostatectomy (LRP) for clinically localized prostatic cancer.Methods:23 cases with localized prostatic cancer underwent LRP in our institution from October 2000 to August 2003. The median age was 64.5 years old, the median PSA was 13 ng/ml and median Gleason score of biopsy specimens was < 7. The operations were performed according to Montsouris technique. Briefly, operations were carried out transperitonealty, combining posterior and anterior approachs to the prostate, transecting the bladder neck, lateral dissection of the prostate, urcthrovesical anastomosis, completing the operation.Results:No death and no conversion rate were observed in this series of 23 cases of LRP. No re-intervention was needed. The median operating time was 325 minutes (range 270 to 660 min) including the lymphadenectomy phase that was considered necessary in the case whose PSA value was 51ng/ml and pathological reading was negative to thoses lymph nodes; The median intraoperative blood loss was 430 ml(rang 200 to 1100 ml). Postoperative bladder catheterization time was 20 days. Surgical positive margin was found in I case of pathlogical stage of pT2b and Casodex 50 mg had been used on this case for 3 mon after the PSA value was < 0.2 ng/ml. Postoperation follow-up of 3 to 24 mo. showed no signs of complications such as urethral stricture or urine incontinence. The PSA concentrations was < 0.3 ng/ml in all cases.Conclusions: LRP provides a clear and magnified anatomical image to allow a more precise and safer dissection.

Objective To investigate the genotype distribution of hepatitis C virus (HCV) in Guangdong Province by linear probe assay (LiPA) and core,non-structural protein 5B (NS5B) sequence analysis,and to evaluate the accuracy of LiPA for genotyping.MethodsOne hundred and ten HCV specimens from chronic hepatitis C (CHC) patients in Guangdong Province were genotyped by both core,NS5B sequence analysis and INNO-LiPA 2.0.The data were then analyzed with SPSS 10.0 software.ResultsAmong the 110 specimens,core and NS5B fragment could be amplified from 97 and 62 specimens,respectively,while both fragments were obtained from 57 specimens. The results of genotyping by core sequence analysis were completely consistent with the results of NS5B sequencing.One hundred and two specimens were classified into five subtypes,i.e.genotype 1a,2a,3a,3b,6a,with frequencies of 61.8％ (64),9.8％ (10),3.9％ (4),3.9％ (4),20.6％ (21),respectively.All but genotype 6 strains can be genotyped correctly by using INNO-LiPA 2.0.However,only subtype 1b and 3b could be genotyped accurately.81.5％ genotype 6a strains were genotyped as 1b by mistake. Conclusions Genotype 6a has become the second most prevalent genotype in Guangdong Province.The LiPA cannot distinguish genotype 6a from 1b strains accurately which needs further investigation.

ObjectiveTo evaluate the effect of laparoscopic cholecystectomy (LC) combined with intraoperative cholangiography (IOC) and intraoperative endoscopic sphincterotomy (IOEST) for the diagnosis and treatment of choledocolithiasis. Methods Statistical analysis was carried out for 106 patients with cholecystocholedocolithiasis diagnosed and treated by LC-IOC-IOEST. Results Sixty-four (60.4%, 64/106 ) patients with preoperative diagnosis of simple gall stone were found with complicated choledocholithisis; LC-IOC -IOEST was successfully performed in 99(93.4%, 99/106) cases. Six cases (6.1%) suffered from mild postoperative acute pancreatitis. Duodenal perforation, bile leakage, peumothorax (0.9%) developed in one each. Duodenal adenocarcinoma was overlooked in one case, and 2 cases (1.8%) suffered from gastric paralysis. Conclusion LC combined with IOC and IOEST was a safe, effective approach to the diagnosis and minimally invasive treatment of choledocholithiasis.
