ObjectiveTo investigate the epidemiology of senile dementia in Shanghai.Methods15158 residents aged 65 or over were selected by stratified random cluster sampling from 3 districts in Shanghai. Two stages was carried to ascertain dementia: in the first stage, Mini Mental State Examination (MMSE) and Activity of Daily Living Scale (ADL) were used as screening tools; in the second stage, DSM-Ⅳ criteria for dementia was applied to diagnosis.ResultsScreening positive rate of MMSE and ADL are both 9.9%. 1271 cases of elderly with dementia were identified. The crude and age-standardized prevalence in residents aged 65 or over was 8.1% and 6.1%. The female, older age, lower education and worse marriage seemed to be more susceptible to senile dementia(P<0.01).ConclusionSenile dementia has become one of major diseases harmful to elderly's health.

ObjectiveTo evaluate probability and severity of behavioral and psychological symptoms in dementia (BPSD) in elderly with dementia in Shanghai.MethodsOn the basis surveyed before, total 1271 elderly with dementia were investigated with the international neuropsychiatric inventory (NPI) to evaluate BPSD.ResultsThe proportion of elderly with dementia that had BPSD was 50.95% , it was 32.17% for clinical significant disturbance (CSD). The symptoms had greatest impact on the caregivers were paranoia (2.32±1.48), followed by abnormal motor behavior (2.30±1.31) and hallucinations (2.16±1.25). The severity rating included mild 620 cases, moderate 238 cases, and severe 406 cases.ConclusionThe incidence rate of BPSD in elderly with dementia was high. The standard of severity grading should be selected with purposes.

ObjectiveTo analyze burden and tolerance of caregivers of elders with dementia in Shanghai.MethodsOn the basis of surveyed before, total 1271 caregivers of elders with dementia were investigated with the questionnaire that concerned the demographic characteristics, influence on body, psychology, life and tolerance.ResultsNearly 60% of the caregivers felt stress, nearly 40% of the caregivers thought that mental pressure had a negative impact on their health as a result of caring patients. Most of the caregivers responded with tolerance to non-adaptive behavior.ConclusionDementia caregivers are old, the burden is heavy. It is necessary to establish a social support system for elderly with dementia as soon as possible.

Objective To improve the success of the urethral stricture repair in males. Methods Chose 101 males of urethral stricture,their median age was 9 years old (range 3 to 57 years old). Of the patients,61 patients had anterior urethral stricture and the posterior urethral stricture occurred in 40 patients. The length of the stricture varied from 0.5 to 2.0 cm. All patients were repaired with the only genital flap suturing the strictural urethra. Results All repairs were completed in 1 stage, follow-up was from 12 to 18 months, excepted for patients with 3 fistula and 3 urethral stricture, 95 patients were voiding a straight stream, the other 6 patients need another surgery. Conclusion It is a good technique to treat urethral stricture with genital flap ff there is short urethral stricture with sufficient genital skin.

OBJECTIVETo study genetic polymorphisms of 20 Y-chromosomal short tandem repeats (STR) in Chaoshan Han population, and to evaluate their value in forensic science.

METHODSTwenty Y-specific STR loci (DYS434, Y-GATA-A10, Y-GATA-H4, DYS438, DYS439, DYS443, DYS444, DYS446, DYS447, DYS448, DYS456, DYS458, DYS460, DYS520, DYS531, DYS557, DYS622, DYS630, DYS635 and DYS709) were amplified by using three fluorescence-labeled multiplex PCR systems and were analyzed by ABI310 genetic analyzer. One hundred and fifty-eight unrelated male individuals of Han population in Chaoshan area were investigated to determine the distribution of allele frequencies and haplotype.

RESULTSThe Y-STR multiplexes developed had followed the published nomenclature and ISFG guidelines for STR analysis. Gene diversity ranged from 0.2506 at DYS434 to 0.8034 at DYS447. A total of 157 different haplotypes were observed, and among these, 156 were unique, while 1 was found for two times. The haplotype diversity value calculated from all 20 loci combined was 0.999998. None of Y-STR allele mutation was observed in the 30 father/ son pairs confirmed by autosomal STR analysis.

CONCLUSIONThe results indicate that the 20 Y-STR loci are highly polymorphic and fathership genealogy inheritance are stable. The three fluorescence-labeled multiplex amplification systems that we constructed are suitable for forensic individual identification and paternity testing in Chaoshan area.

The aim of this study was to evaluate the predictive value of the polymorphism Glutathione S-transferase P1 (GSTP1) Ile(105)Val on oxaliplatin/5-FU-based chemotherapy in advanced gastric cancer. Patients with advanced gastric cancer accepted oxaliplatin/5-FU-based chemotherapy as first-line chemotherapy were investigated. GSTP1 Ile(105)Val polymorphism was detected by TaqMan-MGB probe allelic discrimination method. Response to treatment was assessed by disease controlled rate. Time to progression, overall survival and toxicities were recorded. Final patient outcomes were as follows: the allele frequencies of GSTP1 were (105)Ile/(105)Ile 52%, (105)Ile/(105)Val 41% and (105)Val/(105)Val 7%. For patients with (105)Ile/(105)Ile and those with at least one (105)Val allele, disease control rate was 39% and 71% (P=0.026), respectively; median time to progression was 4.0 and 7.0 months (P=0.002); median overall survival time was 7.0 and 9.5 months (P=0.002). Neurological toxicity was more frequently occurred in patients with two (105)Ile alleles (P=0.005). In conclusion, patients with at least one (105)Val allele have better prognosis and response to oxaliplatin/5-FU-based regimen as first-line treatment for patients with advanced gastric cancer.

OBJECTIVETo assess the association between single nucleotide polymorphisms (SNPs) of mannose-binding lectin 2 gene (MBL2) (rs1800450, rs1800451 and rs11003125) and protein kinase C-beta 1 gene (PRKC beta 1) (rs3700106, rs2575390) with diabetic macroangiopathy in northern Chinese Han population.

METHODSThe samples have included 318 type 2 diabetes mellitus (T2DM) patients and 448 normoglycemic controls. The five SNPs were determined by a Multiplex SnaPshot method. Biochemical indices such as fasting plasma-glucose, triglyceride and total cholesterol were also measured. Linkage disequilibrium and haplotype analysis were carried out for all samples using Haploview 4.2. Additive model was applied to assess the effect of interaction between SNPs and environment factors on macrovascular complications.

RESULTSGenotypic frequencies of rs11003125 have differed significantly between the controls and patients with coronary heart disease and peripheral vascular disease (P=0.024 and 0.004, respectively). The allele frequency of rs11003125 was also statistically significant between the two groups (P=0.014 and 0.001, respectively). Compared with patients without macrovascular complications, the allele frequency of rs11003125 was significantly different in patients with peripheral vascular disease (P=0.031). No significant differences were found between the distribution of the genotype frequency and allele frequencies of other variants. Haplotype analysis indicated that, compared with controls and patients without macrovascular complications, individuals with G allele of rs1800450 and C allele of rs11003125 had a higher risk for macrovascular complications.

CONCLUSIONThe rs11003125 polymorphism located in the promoter region of MBL2 gene is associated with macrovascular complications of T2DM in northern Chinese Han population. G allele of rs1800450 and C allele of rs11003125 may be risk factors for macrovascular complications. There were additive interactive effects for rs11003125 polymorphism (GC+CC) and hypertension, diabetic nephropathy, diabetic neuropathy and diabetic retinopathy on macrovascular complications.
