Bladder cancer is a common tumor with a high rate of recurrence and quick progression.Many biomarkers for the detection of bladder cancer have been identified,but none has been reported to date to have sufficient sensitivity and specificity.Recent researches are concentrated on p53,Rb,Cyclin D,P27kip-1,FGFR3,Cadherin,Survivin,Aurora,MMP,VEGF and DNA Methylation.In spite of their different sensitivities for bladder cancer of different stages or degrees,these biomarkers are valuable for its diagnosis and prognosis.

The polymorphisms of paraoxonase 1 ( PON 1 ) and ApoE gene in 192 patients with type 2diabetes mellitus (DM group) , 116 cases of atherosclerosis (AS) without DM (AS group), and 105 normal subjects (NC group ) were detected by means of PCR-restriction fragment length polymorphism. The serum concentration of Ox-LDL was determined by enzyme linked immunosorbent assay. The results showed that plasma Ox-LDL level in DM group was higher than those in AS and NC groups[(754.2±279.9 vs 526. 1±186.2 and 421.1 ± 163.2 )μg/L, P<0.01]. Ox-LDL level in the patients with QQ genotype of PON 1 was higher than those in QR and RR genotypes in type 2 DM[(846.6±147.5 vs 763.4±126. 7 and 7 1 3.2 ±132.4 ) μg/L, P<0. 0l],and Ox-LDL level in the patients with ε3/4+ ε4/4 genotype of ApoE was also higher than those in ε3/3 and ε2/2 + ε2/3 geneotypes in type 2 DM[( 824.3 ± 173.5 vs 741.6± 182. 5 and 718.3 ± 167.5 ) μg/L, P<0.05], but the difference was not found in atherosclerosis without DM. Multiple regression analysis showed that disease duration, PON1 and ApoE genotypes were the independent predictors of plasma Ox-LDL level in patients with type 2 DM.

Objective To prepare ?-CD(?-cyclodextrin) inclusion compounds and PEG- 4000[poly-(ethylene glycol) 4000] solid dispersions of mefenamic acid (MFA)in order to improve its dissolution. Methods The inclusion compounds of MFA were prepared using saturated ?-CD solution method by orthogonal test. The solid dispersions were prepared using melt-cool process with PEG- 4000 as a carrier. The inclusion compounds and solid dispersions were identified by differential scanning calorimetry (DSC) gram and their dissolution rates were tested in pH8.0 buffer solution. Results The suitable condition for preparing ?-CD inclusion compounds of MFA industrially was the weight ratio of 1∶4 between MFA and ?-CD, agitating for 4 h at 70 ℃. The suitable proportion for preparing solid dispersions of MFA was the weight ratio of 1∶4 between MFA and PEG- 4000. Conclusion Dissolution rates of MFA are apparently improved in inclusion compounds and PEG- 4000 solid dispersions, and the solubility of MFA is apparently increased by 2～3 times in inclusion compounds and PEG- 4000 solid dispersions.

OBJECTIVE: To evaluate the use of oral hypoglycemic drugs in our hospital in order to provide an reference for rational use of drugs in clinic. METHODS: DDDs, sales volume, and daily expenses of drugs in our hospital from 2001to 2003 were analyzed with the method of DDD analysis. RESULTS: The varieties, quantities and sales volumes of oral hypoglycemic drugs increased year by year. The top 3 hypoglycemic drugs in respect of DDDs were dimethylbigmide, gliclazide, and glipizide. The top 3 hypoglycemic drugs in respect of sales volume were glipizide, acarbose, and dimethylbimide. The ratio of sales volume sequencing to that of DDDs was between 0.2～4. CONCLUSIONS: Gliclazide and dimethylbimide are most widely used and their prices are reasonable; Acarbose is expensive, and its sales volume has not grown in pace with DDDs.

Objective To identify the genetic mutation of the gene FOXL2 in a big Chinese family with 4 generations,8 patients and 11 health members which have blepharophimosis-ptosis-epicanthus-inversus syndrome(BPES) type Ⅰassociated with ovarian dysfunction,and demonstrate the correlation between clinical phenotype and genotype.Methods The peripheral blood samples,with 5ml EDTA as decoagulant,from 8 patients and 11 health people in a big Chinese family affected with BPES typeⅠwere collected.The genomic DNA from peripheral blood leukocytes was extracted.7 pairs of primers were designed by the Oligo6 according to the sequence of the FOXL2 gene(GenBank ID AF301906).The exons and the putative core promoter of the FOXL2 gene were amplified using polymerase chain reaction(PCR),and mutation was analyzed by sequencing DNA fragments.Results A novel nonsense mutation at nucleotides in the FOXL2 gene was found in the eight affected patients of the big Chinese family with BPES typeⅠ.No mutation was found in any of the health members in the big Chinese family.Conclusion This is the first reported mutation of the FOXL2 gene in a big Chinese family with BPES typeⅠ.This nonsense mutation in the FOXL2 gene may be an important pathogenesis for the BPES typeⅠin this big Chinese family.It is the first time that a novel nonsense mutation in the FOXL2 gene has ever been found to demonstrate a close correlation between genotype and BPES typeⅠ.

Objective To discuss the clinical effect and safety of the unilateral C2 pedicle screw-plate(C2PSP)combined with contralateral C2 laminar screw-rod(C2LSR)for atlanto-axial joint and occipital cervical fixation.Methods 11 patients were treated by internal fixation with pedicle screw plate system combined with contralateral C2 laminar screw rod system.The cause of atlantoaxial instability was fresh type Ⅱ odontoid fracture in 5 patients,old odontoid fracture in 3 patients,occipitalization mal-formation in 2 patients,atlantoaxial instability in 2 patients.6 patients had small pedicle of the vertebral arch,2 patients had a high-riding vertebral artery(VA),2 patients had an asymmetrical VA,1 patient re-ceived a revision operation.9 patients performed C1-2 fixation,2 patients performed occipito-cervical fixa-tion.1 patient of irreducible atlantoaxial dislocation also performed anterior atlantoaxial joint release before posterior Fixation.All patients performed bone grafting to achieve a further occipito-cervical fusion or at-lantoaxial fusion.Before and after the operation,the neurologic function was scored according JOA scale. The X-ray and CT-scan also performed at regular intervals to evaluate cervical alignment and the fusion. Results All cases were complete reposition without vertebral artery,spinal cord or never root injuried.All patients were followed up for 6-32 months ( mean 16 months ),clinical symptom were improved visibly. The mean postoperative JOA scores was 14.9(13-16).The postoperative JOA score improvement rate was 76%-92%,and its mean value was 83%.All patients achieved bone fusion approved by CT scan after six months of operation.The reduction maintained well and the internal fixation was well positioned.Conclu-sion It will be an effective and safe way to achieve atlantoaxial fusion by posterior unilateral C2 pedicle screwing combined with contralateral C2 laminar screwing,but this study had not including clinical com-parative study.

Objective To compare the perinipple round-block technique with the conventional periareolar round-block technique in areolar reduction operations.Methods A total of 37 patients who underwent areolar reduction operations in our department were randomly allocated into two groups:Group A (19 patients) received a conventional periareolar round-block technique,while group B (18 patients) through a new perinipple round-block technique.In the latter approach,an intraareolar donut of pigmented skin was deepithelialized,and the exposed areolar dermis was then telescoped inward and stretch-anchored to an imaginary circular line situated beneath the breast skin areola junction.The roundblock technique was then utilized to approximate the skin edges,resulting in a minimal scar,totally inconspicuous,confined to the immediate perinipple area.The operative time,perioperative complications,scars,absorption time of the skin folds,the sensation of the nipple-areolar complex and the patients' satisfaction were compared between the two groups.Results The mean operative time of group A and group B was 40.5 min and 45.8 min,respectively (P＜0.05).No perioperative complications were found in these two groups.No patient had experienced permanent nipple sensory changes.The skin folds absorption time of group A was 4.34 months,while the time of group B was 8.78 months (P＜0.01).The perinipple round-block technique produced a more inconspicuous scar with a better aesthetic results.Conclusions The traditional periareolar round-block technique leaves a sharply demarcated areola by a circular scar which has a totally unnatural and artificial look.As for the perinipple round-block technique,the incision as well as any residual cutaneous wrinkling or puckering is well concealed by the dome of the nipple and the areolar,but it needs a longer skin folds absorption time.

Objective To investigate the infection sites,the offending species,diagnosis and prognosis of deep fungal infections (DFI) in patients with systemic lupus erythcmatosus (SLE).Methods Fifty-one patients with fungal infections in 1466 SLE patients admitted to Peking Union Medical College (PUMC) Hospital from 2000 to 2006 were reviewed retrospectively.Results Candida albicans was ranked the first pathogen,followed by ncoformans and Aspergillus species.The infection sites were lungs,cerebral meninges and blood in the order of prevalence.The overall mortality was 20%(10/51).Aspergillasis carried the highest mortality which couht be as high as 80%.Hypoproteinemia,multiple focus of fungal infections,Aspergillasis and fungemia might he the independent risk factor for mortality.Conclusion Candida albicans is the most frequent species of fungal infections in SLE patients.Iungs are the most prevalent location of infection.Earlier diagnosis is important.Special attention should be paid to aspergillasis.
