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 the effect of arsenic trioxide (As2O3) on expression of vascular endothelial growth factor-C (VEGF-C) and its receptor VEGFR-3 in gastric cancer in order to clarify the role of As2O3 in lymphangiogenesis and metastasis of tumor. The gastric cancer model was established in nude mice by using gastric cancer cell line SGC-7901. As2O3 was injected to the two treatment groups (2.5 mg/kg and 5 mg/kg) and the same volume of saline solution was injected to the control group. Expression of VEGF-C and VEGFR-3 were detected by immunohistochemistry and were analyzed with QWin550cW image Acquiring & Analysis System. The results showed that the expression of VEGF-C and VEGFR-3 in cancer cells significantly reduced in the arsenic -treated groups. The expression of VEGF-C and VEGFR-3 in 5 mg/kg group was significantly less than that in 2.5 mg/kg group. The gray ratio analysis confirmed that there were significant difference between control group and two treated group, as well as between 2.5 mg/kg-treated group and 5 mg/kg-treated group. It is concluded that As2O3 can inhibit expression of VEGF-C and VEGFR-3 of human gastric cancer xenografts in nude mice, which suggests that As2O3 may inhibit the lymphangiogenesis by suppressing the expression of VEGF-C and VEGFR-3.

OBJECTIVETo investigate the apoptosis-related genes and protein expression patterns in relation to classical Hodgkin lymphomas (CHL) and the origin of H/RS cell.

METHODSSixty-two cases of CHL were retrieved from Shanxi Tumor Hospital files. An ABC method was used to detect the expression of bcl-2, CD3, CD20, CD30, CD15 and CD10, a double immunohistochemical method to study the H/RS cells P53 expression, a double immunohistochemical ABC-DNA end labeling technique to detect the apoptosis, a double immunohistochemical ABC- in situ hybridization technique to detect the expression of kappa mRNA and lambda mRNA, and a multiple mark techniques to detect the distribution of background non-neoplastic T and B cells.

RESULTOf 62 CHL, 14 (22.58%) were p53 positive and 35 (56.45%) bcl-2 positive. Apoptosis was found in the background non-neoplastic cells in all of the cases, but in H/RS cells in only 10 of 62 cases. There was a significant reverse correlation between bcl-2 expression and apoptosis in H/RS cells (P = 0.02). CD30 positive H/RS cells were observed in all cases, whereas CD15 positive in only 41 cases, and CD20 positive in 8 cases. None was positive for CD3, MPO, bcl-6, CD10, kappa RNA and lambda RNA in H/RS cells. The H/RS cells were surrounded by non-neoplastic T cells looked like a rosette and the outer periphery was B cells.

CONCLUSIONSThe H/RS cell of classical Hodgkin lymphoma has a great variety of B lineage markers. The characteristic distributions of T, B and H/RS cells may serve as a reference for the diagnosis. Multiple marker technique is able to highlight the critical cells, and facilitate the study of H/RS cells. Abnormal expression of P53 may not play a major role in CHL. Over expression of bcl-2 may be linked to blockage of apoptosis in CHL.

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.
