OBJECTIVEPrader-Willi syndrome (PWS) is an example of a human genetic disorder that involves imprinting genes on the proximal long arm of chromosome 15 and SNRPN gene as a candidate gene for this syndrome. The purpose of this study was to show the molecular genetic defects and genomic imprinting basis in Chinese PWS patients and to evaluate the clinical applications of a differential diagnostic test for PWS.

METHODSFluorescence in situ hybridization (FISH) and methylation-specific PCR (MSPCR) techniques were applied for 4 clinically suspected PWS patients. Using three probes, including SNRPN probe for identification of the critical locus in PWS region, D15Z1 and PML control probes for identification of the 15p arm and 15q arm, the authors detected the deletions 15q in PWS. MSPCR was based on sodium bisulfite treatment of DNA and PCR primers specific for the maternal and paternal allele.

RESULTSWhen hybridized with mixed probes, it was found in 2 patients that the central specific signal was absent, but both the flanking control signals were retained, indicating SNRPN gene deletion of chromosome 15q11-13. Bisulfite-modified DNA from all PWS children amplified with methylated allele-specific primer pair showed only maternal 131bp PCR product, indicating the maternal uniparental disomy (UPD15).

CONCLUSIONGenomic imprinting plays an important role in the molecular pathogenesis of PWS that caused by paternal microdeletions of 15q11-q13 or maternal UPD of chromosome 15. The basic defect seemed to be an absence of function of PWS genes that are normally expressed only from the paternal chromosome 15. MSPCR is a rapid and simple PCR-based assay compared with other cyto-molecular tests and its results were consistent with the clinical diagnosis of PWS, so it seems to be a reliable diagnostic method for PWS patients who show abnormal methylation at SNRPN. The genetic differential tests for PWS are important in determining familial recurrence risk.

OBJECTIVETo observe the intervention effect of acupuncture on early onset of selec- tive serotonin reuptake inhibitors (SSRIs) in treating depressive disorder, and to study its effect on ser- um 5-HT and unbalanced inflammatory cytokines secreted by TH1/TH2.

METHODSTotally 90 patients with depressive disorder were randomly assigned to the drug control group (as the control group, 45 cases) and the acupuncture combined drug treatment group (as the treatment group, 45 cases). All patients were treated for 4 consecutive weeks. Another 45 healthy subjects were recruited as a healthy control group. The effect of acupuncture on early onset of SSRls in treating acute phase depressive disorder pa- tients was evaluated by HAMD score in the control group and the treatment group before treatment,and at weekends of the 1st, 2nd, and 4th week after treatment. Besides, their serum levels of 5-HT, IL-1β and IL-6 (secreted by TH1), and IL-4 and IL-10 (secreted by TH2) were detected before treatment and after treatment at the weekend of the 4th week.

RESULTSCompared with the healthy control group,serum lev- els of 5-HT, IL-4, and IL-10 decreased in the two drug-treated groups before treatment (P < 0.01); serum levels of IL-1β and IL-6 increased (P <0.01). Compared with before treatment in the same group, HAMD score decreased in the control group at weekends of the 2nd and the 4th week after treatment (P < 0.01); HAMD scores decreased in the treatment group at weekends of the 1st, 2nd, 3rd,and 4th week after treatment (P < 0.01); serum levels of 5-HT, IL-4, and IL-10 increased,serum levels of IL-1β and IL- 6 decreased in the two drug-treated groups after treatment (all P < 0.01). Compared with the control group at the same time point,HAMD scores decreased in the treatment group at weekends of the 1st, 2nd,3rd,and 4th week after treatment (P < 0.01),serum levels of 5-HT, IL-4, and IL-10 increased (P < 0.05, P < 0.01), serum levels of IL-6 decreased (P < 0. 01).

CONCLUSIONAcupuncture could accelerate early onset of SSRIs in treating acute phase depressive disorder, and effectively regulate serum 5-HT levels and inflammatory cytokines secreted by TH1/TH2.

Objective To measure and define the distribution of left gastric lymph nodes.Meth- ods From Jan.2004 to Apr.2005,silver clips were set around the root of the left gastric artery in 124 pa- tients with esophageal and gastric cardia carcinoma,X-ray films at 0?and 90?simulator gantry in the radio- therapeutic position were taken.Then,the data of the superior,lower,left,right,anterior and posterior bor- der in each patient was recorded.With SAS 8.02 software,data of minimum area which covered the left gas- tric lymph node in different incidences were obtained.Results According to the analysis of Shapiro- Wilk,Kolmogorov-Smimov,Cramer-von Mises and Anderson-Darling tests,each border was of normal distri- bution,with equal frequency in the male and female,despite the actual results in different genders.Pearson Correlation Coefficients analysis did not suggest a significant relationship between the border and height, weight and size of vertebrae,which formed the minimum area covering the left gastric area at frequency of 100%,95%,90% and 85%,which were drawn out through the calculation.Conclusions Aiming at completely identifying the normal distribution of the left gastric lymph node,more patients are required to be in the pool.For the time being,location in the left gastric area can be obtained from details of the results in the present study.

Background: Numerous studies have demonstrated that patients with Parkinson's disease (PD) have a higher prevalence of substantia nigra (SN) hyperechogenicity compared with controls. Our aim was to explore the neuroimaging characteristics of transcranial sonography (TCS) of patients with PD and those with PD with dementia (PDD). The correlation between the echogenicity of the SN and clinical symptoms in Chinese patients with PDD was also assessed. Methods: The ratios of SN hyperechogenicity (SN+), maximum sizes of SN+, and widths of third ventricle (TV) were measured using TCS for all the recruited patients. Data were analyzed using one?way analysis of variance, rank?sum test, Chi?square test, and receiver?operating characteristic (ROC) curve analysis. Results: The final statistical analysis included 46 PDD patients, 52 PD patients, and 40 controls. There were no significant differences in ratios of SN+ and maximum sizes of SN+ between PDD and PD groups (P > 0.05). TV widths were significantly larger in PDD group (7.1 ± 1.9 mm) than in PD group (6.0 ± 2.0 mm) and controls (5.9 ± 1.5 mm, P < 0.05); however, the ratios of enlarged TV did not differ among the three groups (P = 0.059). When cutoff value was set at 6.8 mm, the TV width had a relatively high sensitivity and specificity in discriminating between PDD and PD groups (P = 0.030) and between PDD group and controls (P = 0.003), based on ROC curve analysis. In PDD patients, SN+ was more frequently detected in akinetic?rigid subgroup, and patients with SN+ showed significantly higher Hoehn and Yahr stage and Nonmotor Symptoms Questionnaire scores (P < 0.05). Conclusions: Compared to Chinese patients with PD, patients with PDD had a wider TV, altered SN sonographic features, and more severe clinical symptoms. Our findings suggest that TCS can be used to assess brain atrophy in PD and may be useful in discriminating between PD with and without dementia.

Objective To explore the clinical effects of stereotactic radiofrequency multitarget lesion on the treatment of senile dementia in patients with mental disorder. Methods Under the CT localization, 18 patients with mental retardation were treated by stereotactic surgery of multi-target lesion.Their therapeutic effects were evaluated by Scale and National Psychosurgery Cooperation Request on Modern Psychosurgery Operation Cure (protocol) in 1990. Results Postoperative follow-up was performed for 12-36 months; 9 patients progressed remarkably; 6 got improvement and only 3 showed no changes; the total effective rate was 83.3%. The scores of brief psychiatric rating scale, social disability screening schedule and scale for assessment of positive symptoms after the treatment were significantly lower than those before the treatment (P＜0.05). Mini-mental state examination showed no changes on the intelligence before and after the treatment (P＞0.05). Conclusion The stereotactic surgery of multi-targets lesion is an effective method in treating senile dementia in patients with mental disorder,with few complications and little influences on the intelligence.

This study was aimed to investigate on effect of As(2)O(3) on expressions of COX-2, MMP-2 and MMP-9 in SGC7901 and K562 cells. SGC7901 and K562 cells were cultured in RPMI 1640 medium and were inoculated in culture medium with different concentrations of As(2)O(3) and at different times. Expressions of COX-2, MMP-2 and MMP-9 in SGC7901 and K562 cells were measured by using Western blot, while the levels of COX-2 mRNA and MMP-2 mRNA were measured with fluorescence quantitative RT-PCR. The results showed that the expression of COX-2, MMP-2 and MMP-9 decreased in dose- and time-dependent manners after treating with As(2)O(3). The levels of COX-2 mRNA and MMP-2 mRNA reduced in groups treated with As(2)O(3). In conclusion, As(2)O(3) inhibits expressions of COX-2, MMP-2 and MMP-9 in K562 and SGC7901 cells, suggesting that As(2)O(3) inhibits tumor development through its effect on angiogenesis involved in solid and hematologic malignancies.

OBJECTIVETo investigate the expression of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9(MMP-9), transforming growth factor beta(1)(TGF-beta(1)) and IV-collagen (C-IV) in kidneys of diabetic rats.

METHODSRat diabetic model was induced by streptozotocin (70 mg/kg), and kidneys were examined pathologically and the expressions of MMP- 2, MMP-9, TGF-beta(1) and C-IV were studied by immunohistochemistry. The results were analyzed by imaging quantitative analysis technique.

RESULTImmunoreactive MMP-2 and MMP-9 were mainly expressed in the mesangial cells, endothelial cells, parietal layer of Bowman's capsule and tubular cells. The expression of MMP-2 was significantly weaker in the glomeluri of diabetic rats than that of the control animals (P<0.05), while the expression of TGF-beta(1) and C-IV in the glomeluri of diabetic rats was significantly stronger than that of the controls (P%lt;0.05). The expression of MMP-9 didn't show significant different in glomeluri of the two groups (P>0.05).

CONCLUSIONExpression of MMP-2 in glomeluri is decreased in diabetic rats, which may be related to the increased TGF-beta(1) and in turns promote the accumulation of C-IV.

OBJECTIVETo explore the secular trend in incidence and mortality rate of gastric cancer in Tianjin and to provide evidence and reference for making prevention and control strategy for gastric cancer.

METHODSData derived from Tianjin cancer registry system were analyzed by descriptive epidemiological method and Joinpoint model. A total of 17990 gastric cancer cases reported in Tianjin from 1981 to 2002, including 12755 males and 5235 females were studied.

RESULTSThe annual percent change (APC) of crude incidence rate for males and females was -0.92% (Z = -3.85, P = 0.001) and -0.79% (Z = -2.67, P = 0.015), while the APC of standard incidence rate was -3.55% (Z = -13.52, P = 0.000) and -3.47% (Z = -12.85, P = 0.000). There was a descending trend of incidence rate in males and females above 45-years-old, however, in male under 45 years it showed an increased trend and in females it kept stable. The APC of crude mortality rate was -1.66% ( Z = -5.79, P = 0.000) for males and -1.84% (Z = -6.02,P = 0.000) for females, while the APC of standard mortality rate was -4.60% ( Z = -15.79, P = 0.000) for females and -5.36% ( Z = -8.28, P = 0.000) for males during 1989-2002. Mortality and incidence ratio also indicated a downward trend.

CONCLUSIONDespite its declining trend in Tianjin, gastric cancer still remains an important public health problem in facing of the aging society and many risk factors.
