Objective To study the effects of combined telmisartan and ramiprll on heart function and renin - angiotensin - aldoste-tone system and ventricle remodeling and brain natriuretie peptide in patients with chronic heart failure (CHF). Methods 100 patientswith chronic heart failure were randomly divided into three groups: telmisartan group (A group, treated with telmisartan 80mg once daily, n =33), ramipril group (B group treated with ramipril 5mg once daily, n =33) and telmisartan plus ramipril group (treated with telmis-artan 40mg plus ramipril 2.5mg once daily, n = 34). Left ventricular end - diastolic dimensions (LVEDD) and left ventricular ejection fraction (LVEF) were assessed, and plasma renin activity (Ren) , angiotensinIl (Angll), aldosterone (Aid) and brain natriuretic pep-tide (BNP) were measured before and after therphy. Results After 6 months of treatment, LVEDD and LVEF were improved in all groups(P < 0.01). All changs were significant in C group than those in A group or B group(P < 0.01). The concentration of Ren were in-creased in all groups(P <0.01). The concentration of Angll was increased in A group and decreased in B group(P <0.01)while there was no difference at pre or post treatment in C group (P > 0.01). The concentration of Ald and BNP was decreased in all groups (P < 0.01). Ald and BNP were decreased more significantly in C group than those in A group or B group. Conclusion Combination of low dose of telmisartan and ramipril therapy has more benificial clinical features than telmisartan or ramipril alone in patients with CHF.

OBJECTIVE:To study the effects of aripiprazole on PC12 cell injury induced by amyloid β-protein(Aβ25-35)and its mechanism. METHODS:PC12 cells were randomized into normal control group,model group (20 μmol/L Aβ25-35),aripiprazole low-concentration,medium-concentration and high-concentration groups(5,10,20 μmol/L aripiprazole+20 μmol/L Aβ25-35). These groups were cultured with culture medium containing relevant medicine for 48 h,with 6 wells in each group. The viability(optical density value)of PC12 cell was measured by MTT assay,and PC12 cell apoptosis was measured by Hoechst staining. The activi-ties of Caspase-3 and Caspase-9 were determined by spectrophotometry. The protein expression of Bcl-2,Bax and PI3K and the phosphorylation of Akt were assayed by Western blot assay. RESULTS:Compared with normal control group,optical density value of model group was decreased while apoptotic rate was increased;the activities of Caspase-3 and Caspase-9,and the protein expres-sion of Bax were increased;the protein expression of Bcl-2 and PI3K,the phosphorylation of Akt were decreased(P<0.01). Com-pared with model group,optical density value of aripiprazole low-concentration,medium-concentration and high-concentration groups were increased,while apoptotic rate and the activities of Caspase-3 and Caspase-9 were decreased;the protein expression of Bcl-2 and PI3K and the phosphorylation of Akt were enhanced;while the protein expression of Bax were decreased in aripiprazole medium-concentration and high-concentration groups(P<0.05 or P<0.01). CONCLUSIONS:Aripiprazole can suppress cell apop-tosis of PC12 cell induced by Aβ25-35,which is related to activating PI3K/Akt signal pathway.

OBJECTIVE To reinforce the management of occupational risks among cleaner employec to lower the occurrence of job related exposure.METHODS Set up a survey to estimate the level of the awareness and knowledge among the cleaner employec about job related exposure and protective procedures in the three medical facilities of Yueqing City.RESULTS From 183 cleaner employec,sharp object cuts accounted for 89.6% per year;45.4% of them only had elementary education or less;39.3% of them wore protective gloves voluntarily during daily work.No one followed the hand hygeine procedures.It showed that the contracted cleaning workers had a huge potential occupational risks.CONCLUSIONS Cleaner employec are the weaker point of occupational exposure protection in the hospitals.Enforceing the mandatory immunization and monitoring their occupational risks and exposures can prevent incidence.

Objective To map the mutation gene of autosomal dominant congenital lamellar cataract in a family pedigree of four generations.Methods A Family with non-syndromic congenital cataract was recruited from the Eye Center of Tongren Hospital affiliated to Capital Medical University.Family history was recorded.Twenty-eight members of the family pedigree(including twelve affected and sixteen unaffected individuals)were enrolled into the study with informed consent.The twelve affected individuals underwent full clinical and ophthalmological examinations to rule out any concomitant disorders.The sixteen unaffected individuals only underwent ophthalmological examination.Blood samples were collected from all the 28 subjects for genomic DNA preparation.Eighteen different genes were previously reported to be associated with non-syndromic autosomal dominant congenital cataract(ADCC).Multiplex polymerase chain reaction(PCR)was carried out with microsatellite markers near to candidate loci related to congenital cataracts.PCR products from each DNA sample were separated on a 6% polyarcylamide gel and analyzed.Exclusion analysis was performed by allele sharing analysis and gene sequencing.Results The clinical phenotype in the family was isolated corroborating autosomal dominant congenital lamellar cataract.No mutation was found in the eighteen genes in all twenty-eight subjects.Eighteen candidate genes were excluded by allele sharing method and gene sequencing.Conclusion All known ADCC loci have been excluded from this family,which further indicates the clinical and genetical heterogeneity of congenital cataract,and an important clue is provided for finding more cataract responsible genes.Further study should be carried out to screen other relevant genes or loci in patients with ADCC.

Three antibodies were used for immunohistochemical study of 15 cases of adenoid cystic carcinoma(6 cases contained normal salivary gland tissue). The results indicated that myoepithelial cell of the normal salivary glands revealed positive reaction of S-100 protein; The basal cells of the straited ducts and excretary ducts revcaled strong positive reaction of keratin. In adenoid cystic carcinoma positive reaction of S-100 prctein and vimentin were found in luminal cells of cribriform pseudocyts and peripheral cells of tumor nests, and the outer layers'cells of tubular stucture and the border cells of trabucula. But the positive reaction of keratin was found in inner cells of tubular and central cells of trabecular patten. It indicated that adenoid cystic carcinoma probably stems from the basic cells of the striated ducts and excretary ducts of normal salivary glands.

Exon 3 termination mutation of phenylalanine hydroxylase (PAH) gene, the only identified one causing classical phenylketonuria (PKU) in Chinese, was detected in fourteen PKU children from Xi'an. The genomic DNA from these patients was amplified by polymerase chain reaction(PCR) and dot hybridied with specific oligonucleotide probes. This mutation is not present in any of these affected children, which indicates that phenylketonuria in Chinese may be caused by other mutations in phenylalanine hydroxylase locus. PCR amplification combining with oligonucleotide dot hybridization is technically feasible for prenatal diagnosis and carrier screening for PKU.
