Abstract
Evidence from previous voxel-based morphometry (VBM) studies indicates that widespread brain regions are involved in Parkinson’s disease with mild cognitive impairment (PD-MCI). However, the spatial localization reported for gray matter (GM) abnormalities is heterogeneous. The aim of the present study was to quantitatively integrate studies on GM abnormalities observed in PD-MCI in order to determine whether a pattern exists. Eligible whole-brain VBM studies were identified by a systematic search of articles in PubMed and EMBASE databases spanning from 1995 to January 1, 2019. A meta-analysis was performed to investigate regional GM abnormalities in PD-MCI. The anisotropic effect size version of seed-based d mapping (AES-SDM) meta-analysis was conducted to explore the GMV differences of PD-MCI compared with PD patients with normal cognitive function (PD-NC). A total of 12 studies comprising 243 PD-MCI patients and 326 PD-NC were included in the meta-analysis. PD-MCI patients showed a robust GM decrease in the left insula and left superior temporal gyrus. Moreover, meta-regression analysis demonstrated that age, PD duration and stage, and Unified Parkinson’s Disease Rating Scale III and Mini-Mental State Examination scores might be partly correlated with the GM abnormalities observed in PD-MCI patients. The convergent findings of this quantitative meta-analysis revealed a characteristic neuroanatomical pattern in PD-MCI. The findings provide some evidence that MCI in PD may result in the breakdown of the insula and temporal gyrus, which may serve as specific regions of interest for further investigations.

Abstract
The aim of this study was to investigate the efficacy, acceptability, and
tolerability of antidepressants in treating post-stroke depression (PSD) by
performing a network meta-analysis of randomized controlled trials of the
current literature. Eligible studies were retrieved from online databases, and
relevant data were extracted. The primary outcome was efficacy as measured by
the mean change in overall depressive symptoms. Secondary outcomes included
discontinued treatment for any reason and specifically due to adverse events.
Fourteen trials were eligible, which included 949 participants and 9
antidepressant treatments. Few significant differences were found for all
outcomes. For the primary outcome, doxepin, paroxetine, and nortriptyline were
significantly more effective than a placebo [standardized mean differences:
−1.93 (95%CI=−3.56 to −0.29), −1.39 (95%CI=−2.59 to −0.21), and −1.25
(95%CI=−2.46 to −0.04), respectively]. Insufficient evidence exists to select a
preferred antidepressant for treating patients with post-stroke depression, and
our study provides little evidence that paroxetine may be the potential choice
when starting treatment for PSD. Future studies with paroxetine and larger
sample sizes, multiple medical centers, and sufficient intervention durations is
needed for improving the current evidence.

Abstract
OBJECTIVE To investigate the effects of histone deacetylase 6 (HDAC6) siRNA on cell proliferation and cell apoptosis of the HeLa cervical carcinoma cell line and the molecular mechanisms involved. METHODS Division was into three groups: A, the untreated group; B, the control siRNA group; and C, the HDAC6 siRNA group. Lipofectamine 2000 was used for siRNA transfection, and Western blot analysis was used to determine the protein levels. Cell proliferation and apoptosis were characterized using a CCK-8 assay and flow cytometry, respectively. RESULTS HDAC6 protein expression in the HDAC6 siRNA-transfection group was significantly lower (P < 0.05) than in the untreated and control siRNA groups. The CCK-8 kit results demonstrated that the proliferation of HeLa cells was clearly inhibited in the HDAC6 siRNA transfection group (P < 0.05). In addition, flow cytometry revealed that the early apoptotic rate (26.0% ± 0.87%) was significantly elevated (P < 0.05) as compared with the untreated group (10.6% ± 1.19%) and control siRNA group (8.61% ± 0.98%). Furthermore, Western blot analysis indicated that bcl-2 protein expression in the HDAC6 siRNA-transfection group was down-regulated, whereas the expression of p21 and bax was up-regulated. CONCLUSION HDAC6 plays an essential role in the occurrence and development of cervical carcinoma, and the down-regulation of HDAC6 expression may be useful molecular therapeutic method.

Abstract
AIM: To study the prognostic role of TAp73α, p53, proliferating cell nuclear antigen (PCNA) and apoptosis in patients with hepatocellular carcinoma (HCC) after surgical tumor ablation.
METHODS: Forty-seven human resected HCC tissues and 42 adjacent non-cancerous tissues were studied with 10 normal liver tissues as control group. TAp73α, p53, and PCNA were detected with Elivision immunohistochemistry. Terminal deoxynucleotidyl transferase (TdT)-mediated d-UTP-biotin nick-end labeling (TUNEL) method was used to detect the apoptosis cells. All clinical and pathological materials were analyzed by SPSS10.0 statistical package.
RESULTS: TAp73α overexpressed in HCC tissues (36.2%) when compared with adjacent non-cancerous tissues (2.38%, P<0.005) and normal liver tissues (0, P<0.01). Mutant type p53 (mt-p53) overexpressed in HCC tissues (38.3%) when contracted with adjacent non-cancerous tissues (16.7%, P<0.05) and normal liver tissues (0, P<0.01). Proliferation index (PI) level in HCC tissues was significantly higher than that in adjacent non-cancerous tissues (30.34%±4.46% vs 27.88%±5.89%, t, P = 0.028). Apoptosis index (AI) level in HCC tissues was higher than that in adjacent non-cancerous tissues (8.62%±2.28% vs 7.38%±2.61%, t, P = 0.019). Expression of TAp73α was associated with lymph node metastasis and mt-p53, with r = 0.407 and 0.265, respectively. Expression of mt-p53 was associated with Edmondson’s stage and AFP, with r = 0.295 and -0.357, respectively. In Kaplan-Meier univariant analysis, TAp73α, AFP, TNM stage, portal vein invasion, liver membrane invasion and HBsAg correlated with prognosis (log rank, P = 0.039, 0.012, 0.002, 0.000, 0.014, 0.007, respectively). Multivariant Cox regression analysis showed that TAp73α, AFP, TNM stage, portal vein invasion, liver membrane invasion and age were independent factors of prognosis.
CONCLUSION: These results suggest that TAp73α can be used as a prognostic indicator of patients with HCC undergoing surgical tumor ablation. AFP, TNM, portal vein invasion, liver membrane invasion and age also have a potency of predicting the prognosis of HCC.

Abstract
AIM: To evaluate the expression of fragile histidine triad (FHIT) gene protein, product of a candidate tumor suppressor, and to investigate the relationship between FHIT, cell apoptosis and proliferation, and pathological features of primary hepatocellular carcinoma (HCC).
METHODS: Forty-seven HCC and ten normal liver specimens were collected during surgical operation between 2001 and 2003. FHIT and proliferating cell nuclear antigen (PCNA) expression were detected by immunohistochemistry, and apoptotic level was evaluated by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay on the tissue sections.
RESULTS: All normal liver tissues showed a strong expression of FHIT, whereas 28 of 47 (59.6%) carcinomas showed a significant loss or absence of FHIT expression (P = 0.001). The proportion of reduced FHIT expression in those carcinomas at stages III-IV (70.6%) and in those with extrahepatic metastasis (86.7%) showed an increasing trend compared with those at stages I-II (30.8%, P = 0.013) and those without metastasis (46.9%, P = 0.010) respectively. Apoptotic incidence in advanced TNM stage carcinoma and those with positive FHIT expression was higher than that in early stage carcinoma (P = 0.030) and in those with negative FHIT expression (P = 0.044) respectively. The proliferating potential of hepatocellular carcinoma was associated with FHIT expression (P = 0.016) and the aggressive feature (P = 0.019). Kaplan-Meier analysis demonstrated that the survival time of these 47 patients correlated with TNM stage, FHIT expression and metastasis.
CONCLUSION: There is marked loss or absence of FHIT expression, as well as abnormal apoptosis-proliferation balance in HCC. FHIT may play an important role in carcinogenesis and development of HCC.

Abstract
AIM: To analyse the prognostic factors in 165 colorectal patients aged ≥ 70.
METHODS: One hundred and sixty-five elderly patients with colorectal cancer diagnosed by histology were entered into the retrospective study between 1994 and 2001. Patients were given optimal operation alone, chemotherapy after operation, or chemotherapy alone according to tumor stage, histology, physical strength, and co-morbid problems. Survival rate was calculated by Kaplan-Meier method, and compared with meaningful variances by Log-rank method. Prognostic factors were analyzed by Cox regression.
RESULTS: The 1, 2, 3, 4, 5 year survival rate (all-cause mortality) was 87.76%, 65.96%, 52.05%, 42.77%, 40.51%, respectively. The mean survival time was 41.89 ± 2.33 months (95%CI: 37.33-46.45 months), and the median survival time was 37 months. Univariate analysis showed that factors such as age, nodal metastasis, treatment method, Duke’s stage, gross findings, kind of histology, and degree of differentiation had influences on the survival rate. Multivariate analysis showed that factors such as treatment method, Duke’s stage, kind of histology and degree of differentiation were independent prognostic factors.
CONCLUSION: This study suggests that the prognosis of elderly colorectal cancer patients is influenced by several factors. Most of elderly patients can endure surgery and/or chemotherapy, and have a long-time survival and good quality of life.

Abstract
AIM: To clone human 15ku selenoprotein gene.
METHODS: H9 human T cells were cultured in RPMI1640 medium supplemented with 100 mL/L fetal calf serum. mRNA was isolated from the cells. cDNA library was constructed by RT-PCR. The human 15ku selenoprotein gene was obtained by PCR and cloned into T vector and sequenced.
RESULTS: A unique cDNA fragment about 1244 bp was obtained. Sequence analysis identified an open reading frame within the cDNA. The gene had an in-frame TGA, which encoded selenocysteine (Sec), and a 3’-UTR SECIS element, which was required for synthesis of selenoprotein. The predicted protein molecular mass was about 15ku (162 residues). The result was identical with human liver 15ku selenoprotein gene published in Genbank.
CONCLUSION: Human 15ku selenoprotein gene can be successfully obtained from T cell line.

Abstract
We made several generic plasmids for construction of recombinant vaccinia virus (rvv) expressing foreign proteins in high yield. Rvvs expressing biologically active Escherichia coli beta-galactosidase (rvv-lacZ) and the cytokine murine GM-CSF (rvv-mGM-CSF) were constructed by using these plasmids. To obtain attenuated rvv, cDNA for these proteins was inserted in the thymidine kinase gene of vaccinia virus. Their expression was controlled by vaccinia early/late promoter, 7.5 K so that these proteins could be expressed in the infected cells throughout the life cycle of the virus. Female C57BL/6 mice were immunized subcutaneously with B16-F10 melanoma cells infected with rvv, and 2 weeks later challenged with viable B16 cells. Mice immunized with rvv-mGM-CSF showed delay in tumor development, smaller tumor volumes and longer survival time compared with unimmunized mice, as well as mice immunized with rvv-lacZ. Mice immunized with rvv-mGM-CSF followed by a booster injection after 1 week responded slightly better than those immunized once, but this difference was not statistically significant. These results suggested that rvv-mGM-CSF could be a promising vaccine for cancer therapy.

Abstract
Cross-neutralization assays were done using 85 strains of poliovirus type 1 with five groups of monoclonal antibodies. These strains were classified into 10 subgroups which had marked differences in antigenicity. Subgroups P1-2 (28%) and P1-5 (43%) were dominant and have been epidemic in China in recent years. These two subgroups were antigenically different from the Sabin-1 strain, but according to their responses to one group of monoclonal antibodies they had antigenic epitopes in common with the Mahoney and Brunhilde strains. Similarly, 91 strains of type 3 poliovirus were classified into six subgroups with another five groups of monoclonal antibodies. The results showed that strain P3/Yunnan/2/84, which was isolated from cases of poliomyelitis in a local epidemic in the Yunnan province of China in 1984, and strain P3/Finland/23127/84, which was isolated in Finland in 1984, were both antigenically different from the Sabin-3 strain and the reference virulent strain.
