OBJECTIVESTo investigate the effect of short interfering RNA targeting MAT 2A on growth and apoptosis of hepatoma cells.

METHODSThe four siRNA against MAT 2A gene were transcript synthesized intracelluarly by expressed templates of plasmid vector pSilence-2.1-U6. We inserted the target sequence of MAT 2A gene into the upstream of the reporter gene in order to construct the recombinant plasmid vector plucA-MAT 2A. The recombinant plasmid and siRNA-producing plasmid were co-transfected into 293 T cells using this construct via lipofectamine methods. The inhibition effect was detected by measuring luciferase activity in the cell lysate to screen the effective siRNA, and then, the effective siRNA was transfected into Bel-7402 cells. The effect of siRNA treatment on the MAT 2A mRNA level and the MAT activity of hepatoma cells were measured. In order to study the effect of short interfering RNA targeting MAT 2A on growth and apoptosis of hepatoma cells, the tumor cell killing rate was analyzed by MTT method and the rate of apoptosis of hepatoma cells was evaluated by flow cytometry.

RESULTSThe two siRNA among the four siRNA displayed inhibitory effect on the lucifermase expression with the inhibitory rates of 81% and 89% respectively. The expression of MAT 2A mRNA in Bel-7402 cells was specifically inhibited and the MAT activity in Bel-7402 cells was decreased. Furthermore, silencing of the MAT 2A gene by RNAi significantly inhibited hepatoma cell growth and led to induction of apoptosis.

CONCLUSIONRNA interference-mediated silencing of MAT 2A gene attenuates growth and induces apoptosis of hepatoma cells; MAT 2A is an ideal target of gene-specific therapy for liver cancer.

OBJECTIVETo evaluate the impact of lymphadenectomy on the relapse and survival of malignant ovarian germ cell tumor (OGCT).

METHODSThe clinical data of 102 OGCT cases treated in Peking Union Medical College Hospital from June 1980 to June 2003 were analyzed retrospectively. All the data about lymphadenectomy during primary and secondary surgery were collected, and other factors related to prognosis were also collected at the same time. Chi-squared test was applied in the univariate analysis related to relapse of disease. Cox model was applied in multivariate analysis related to relapse and survival of disease.

RESULTSPelvic and paraaortic lymph node metastasis was not significantly related to prognosis in primary and secondary treated patients. Lymphadenectomy showed no significant impact on disease relapse and survival. In the primary treatment, International Federation of Gynecology and Obstetrics (FIGO) staging, chemotherapy regimen, residual tumor and lymphadenectomy were the significant factors related to the relapse. After being stratified for the chemotherapy regimen, lymphadenectomy was not significantly related to the relapse in bleomycin +etoposide +cisplatin or cisplatin +vincristine +bleomycin regimen group, and lymphadenectomy could prevent relapse in no chemotherapy or other chemotherapy regimen group. In relapsed patients, only residual tumor was significantly related to survival time after relapse.

CONCLUSIONSPelvic lymph node metastasis is not the significant risk factor related to prognosis. Lymphadenectomy may have a beneficial effect on survival, although such effect is not significant. Although lymphadenectomy provides important information for prognosis, they provide little benefit to those patients already requiring chemotherapy based on the original operative findings. Lymphadenectomy should be performed to primary or relapsed patients by an expert surgical team.

BACKGROUNDRecent studies have suggested that susceptibility to major depressive disorder (MDD) might be related to the serotonin 1A receptor (5-HTR1A) C (-1019) G polymorphism. In this study, we aimed to assess the association between 5-HTR1A C (-1019) G polymorphism and MDD in the Northern Han ethnic group of China.

METHODSThe C (-1019) G of 5-HTR1A was detected with polymerase chain reaction (PCR) in 400 patients with MDD and 400 unrelated age- and sex-matched healthy control subjects. Association between the C (-1019) G and MDD was statistically analyzed.

RESULTSThere was a statistically significant difference between MDD patients and controls in both the genotype distribution (Chi(2) = 10.913, df = 2, P = 0.004) and the allele frequency (Chi(2) = 10.379, df = 1, P = 0.001), and a significant difference in the genotype distribution and the allele frequency was found both in the female subjects (Genotype distribution: Chi(2) = 15.406, df = 2, P = 0.000; allele frequency: Chi(2) = 15.552, df = 1, P = 0.000) and the late-onset subjects (Genotype distribution: Chi(2) = 7.771, df = 2, P = 0.021; allele frequency: Chi(2) = 8.007, df = 1, P = 0.005) in the two groups.

CONCLUSIONThese results suggest that 5-HTR1A C (-1019) G polymorphism is probably associated with MDD and it is likely to be the susceptible gene locus for the female and late-onset MDD.

OBJECTIVETo compare the relation between the preoperative functional magnetic resonance imaging (fMRI) with blood oxygen level dependent (BOLD) technique and intraoperative motor evoked potential (MEP) monitoring for cortical mapping of primary motor cortex in patients with tumors near the central area. And to determine whether non-invasive preoperative fMRI can provide results equivalent to those achieved with the invasive neurosurgical "gold standard".

METHODSA prospective study of 16 patients with various pathological tumors of the central area was conducted. Preoperative fMRI scans using the BOLD contrast technique in each patient were performed. An activation scan was achieved by using a motor task paradigm, which consisted of simple flexion-extension finger movements and finger-to-thumb touching in a repeating pattern. The anatomical structure was delineated by the T(1)-weighted three-dimensional fast spoiled gradient recalled sequence (3D/FSPGR) immediately afterward. The BOLD images were overlaid on the T(1)-weighted 3D/FSPGR images, and then co-registered to the neuronavigation system. The fMRI activations were documented by using a neuronavigation system in sequence, and compared to standardized intraoperative MEP monitoring, which included direct cortical electrical stimulation (DCES) or transcranial cortical electrical stimulation (TCES) or their combination. The compound muscle action potentials of forearm flexor and hand muscle responses were recorded during either TCES or DCES. Two techniques were compared to determine the accuracy for cortical mapping of primary motor areas with fMRI.

RESULTSOverall, the intraoperative MEP monitoring showed good correlation with fMRI activation in 92.3% of cases. The coincidence rate, however, was 100.0% between TCES and fMRI, and 66.7% between DCES and fMRI respectively. There was no statistically difference between two cortical mapping techniques, chi-square test of paired comparison of enumeration data, P < 0.01.

CONCLUSIONBOLD fMRI was a high sensitive and reliable technique to locate the position of the primary motor areas and their spatial relation with adjacent tumor, especially for the presurgical planning in patients with central area brain tumor.

OBJECTIVESTo observe the effects of renal ischemic postconditioning (RI-Post) on myocardial apoptosis in rabbits with acute myocardial ischemia and reperfusion.

METHODSAll rabbits were subjected to 60 minutes ischemia by left anterior descending coronary artery occlusion (LADO) and 6 hours reperfusion. The rabbits are randomly divided into 3 groups (n = 8 in each group): (1) Ischemia-reperfusion (IR): LADO and reperfusion without additional intervention; (2) RI-Post: after 60 minutes of LADO, the left renal artery was occluded for 30 seconds and reperfused for 30 seconds and repeated 3 times, then the coronary artery was reperfused for 6 hours; (3) Medication intervention (MI): 10 minutes before coronary reperfusion, rabbits were treated with PKC antagonist GF109203X (0.05 mg/kg, IV), followed by RI-Post treatment and 6 hours coronary reperfusion. Myocardial apoptosis was measured by TUNEL and the myocardial Bcl-2 and Bax protein expressions were assessed by immunohistochemistry.

RESULTSCompared with the IR group and the MI group, myocardial apoptosis was significantly reduced (P < 0.05) and the Bcl-2 protein expression increased (P < 0.01) while the Bax protein expression decreased (P < 0.05) in the RI-Post group.

CONCLUSIONSRemote renal postconditioning applied right before the onset of coronary artery reperfusion can reduce the myocardial apoptosis induced by myocardial ischemia and reperfusion and up-regulate Bcl-2 while down-regulate Bax expression possibly by activation of protein kinase C.

Mutations in the synaptic nuclear envelope protein 1 (SYNE1) gene are associated with substantial clinical heterogeneity. Here, we report the first case of SYNE1 ataxia in Taiwan due to two novel truncating mutations. Our patient, a 53-year-old female, exhibited pure cerebellar ataxia with c.1922del in exon 18 and c. C3883T mutations in exon 31. Previous studies have indicated that the prevalence of SYNE1 ataxia among East Asian populations is low. In this study, we identified 27 cases of SYNE1 ataxia from 22 families in East Asia. Of the 28 patients recruited in this study (including our patient), 10 exhibited pure cerebellar ataxia, and 18 exhibited ataxia plus syndromes. We could not find an exact correlation between genotypes and phenotypes. Additionally, we established a precise molecular diagnosis in our patient’s family and extended the findings on the ethnic, phenotypic, and genotypic diversity of the SYNE1 mutational spectrum.

Objective: A meta-analysis of locus-based genome-wide association studies recently identified a relationship between AXIN1 and Parkinson’s disease (PD). Few studies of Asian populations, however, have reported such a genetic association. The influences of rs13337493, rs758033, and rs2361988, three PD-associated genetic variants of AXIN1, were investigated in the present study because AXIN1 is related to Wnt/β-catenin signaling. Methods: A total of 2,418 individuals were enrolled in our Taiwanese cohort for analysis of the genotypic and allelic frequency. Polymerase chain reaction–restriction fragment length polymorphism analysis was employed for rs13337493 genotyping, and the Agena MassARRAY platform (Agena Bioscience, San Diego, CA, USA) was used for rs758033 and rs2361988 genotyping in 672 patients with PD and 392 controls. Taiwan Biobank data of another 1,354 healthy controls were subjected to whole-genome sequencing performed using Illumina platforms at approximately 30× average depth. Results: Our results revealed that rs758033 {odds ratios [OR] (95% confidence interval [CI]) = 0.267 [0.064, 0.795], p = 0.014} was associated with the risk of PD, and there was a trend toward a protective effect of rs2361988 (OR [95% CI] = 0.296 [0.071, 0.884], p = 0.026) under the recessive model. The TT genotype of rs758033 (OR [95% CI] = 0.271 [0.065, 0.805], p = 0.015) and the CC genotype of rs2361988 (OR [95% CI] = 0.305 [0.073, 0.913], p = 0.031) were less common in the PD group than in the non-PD group. Conclusion Our findings indicate that the rs758033 and rs2361988 polymorphisms of AXIN1 may affect the risk of PD in the Taiwanese population.
