Objective To study the relationship between in situ telomerase activity and the expressin of bcl-2 and p53 proteins in human ovarian epithelial tumors(OETs), and explore their effect in pathogenesis of ovarian cystadenocarcinoma. Methods The telomerase activity of ovarian epithelial tumors was measured by in situ telomerase activity labeling (ISLT), and bcl-2 and p53 expression was detected by SP immunohistochemical method. Results ⑴The positive rates of telomerase in ovarian cystadenocarcinomas(OCAC), their surrounding ovarian tissues(SOT),borderline cystadenomas(BCA),and cystadenomas(CA)were 92 3%(24/26), 0(0/26), 42 8%(9/21) and 0(0/15) respectively, and the positive rate was significantly higher in OCAC than that in SOT, BCA and CA(P0 05); ⑵The positive rates of Bcl-2 in OCAC, SOT, BCA and CA were 65 38%(17/26), 0(0/26), 52 38%(11/21) and 26 66%(4/15) respectively, which were significantly higher in OCAC and BCA than those in SOT and CA(P0 05). Conclusion The results indicated that overexpression of bcl-2 protein may be related to telomerase activation, the telomerase activation induced by bcl-2 overexpression may result in malignant transformation of ovarian epithelials, and p53 mutation may not affect telomerase activity during ovarian cystadenocarcinogenesis.

Objective:To explore the efficacy of nimodipine in treating cognitive impairment of cerebral small vessel disease (CSVD) and the value of magnetic resonance diffusion tensor imaging (DTI) in CSVD.Methods:A total of 80 patients with CVSD and cognitive dysfunction who admitted to Suzhou Municipal Hospital from February 2018 to February 2019 were selected, and the patients were divided into control group (40 patiengts) and observation group (40 patients) by random number table method. The control group received basic treatment and donepezil, and the observation group added nimodipine on the basis of control group. All patients were followed up for 12 months. Before treatment, 6 months after treatment and 12 months after treatment, the patients’Montreal cognitive assessment scale (MoCA) score, daily living ability scale (ADL) score, and Tinetti balance and gait analysis(TGA) were recorded. The levels of total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C), homocysteine (Hcy) and high-sensitivity C-reactive protein (hs-CRP) before and after treatment were recorded. The changes of DTI data before and after 12 months′ treatment in the two groups were recorded.Results:The MoCA score, ADL score, and TGA score of the two groups were higher than those before treatment and at 6 months and 12 months after treatment, and those 12 months after treatment were higher than those at 6 months after treatment. There were significant differences ( P<0.05). The MoCA and ADL scores of the observation group were higher than those of the control group at 6 and 12 months after treatment at 6 months: (24.61 ± 2.54) scores vs. (22.21 ± 2.83) scores, (71.53 ± 6.25) scores vs. ( 69.51 ± 6.81) scores; 12 months: (26.39 ± 2.16) scores vs. (23.76 ± 2.64) scores, (78.39 ± 5.76) scores vs. (72.39 ± 6.12) scores, P<0.05. At 6 months and 12 months after treatment, the visual space and execution ability, delayed memory, and orientation scores were higher than those before treatment, and in the observation group 12 months after treatment was higher than those 6 months after treatment: (5.97 ± 1.37) scores vs. (5.36 ± 1.29) scores, P<0.05. The observation group′s visual space and executive ability, abstract thinking, delayed memory, and orientation score were higher than those in the control group at the same period ( P<0.05). The levels of TC, TG, LDL-C, Hcy and hs-CRP of the two groups after treatment for 6 and 12 months were lower than those before treatment, and the levels of these index at 12 months after treatment were lower than those at 6 months after treatment ( P<0.05). The levels of Hcy and hs-CRP in the observation group were lower than those in the control group at 12 months after treatment, and Hcy was lower than that in the control group at 6 months after treatment ( P<0.05). After treatment, the fractional anisotropy (FA) values of the center, frontal lobe, and parietal lobe of both sides of the two groups were higher than those before treatment, and the difference in the observation group before and after treatment was higher than that of the control group ( P<0.05). After treatment, the mean diffusivity (MD) values of both frontal lobe and parietal lobe of the two groups were lower than those before treatment, and the difference between the observation group before and after treatment was higher than that of the control group ( P<0.05). Conclusions:Nimodipine has a good effect on the treatment of CVSD, which can effectively improve the patients′ cognitive impairment and other symptoms. DTI can sensitively sense the white matter integrity and cerebral blood flow perfusion of patients, which has a positive significance for the prevention and treatment of CVSD.

OBJECTIVETo study the anti-immune inflammation efficacy and toxicity of Tripterygium wilfordii decoction, in order to provide experimental basis for studies on its "efficacy-toxicity" correlation.

METHODThe delayed hypersensitivity model was established by dinitrofluorobenzene in mice. Different doses of T. wilfordii decoction was administered for 5 consecutive days. The ear swelling inhibition ratio and the toxic action were observed. After the final administration, the biochemical indexes of PGE2, TNF-α, IL-2, ALT, AST, PA, TBA, TBIL in serum were detected, and the visceral indexes of heart, liver, spleen and kidney were measured.

RESULTThe DNFB-induced ear swelling could be notably inhibited by multiple oral administration of T. wilfordii decoction, with the ED50 and its 95% confidence limit of 0.34 (0.21-0.42) g x kg(-1). The contents of PGE2, TNF-α, IL-2 in serum decreased in a dose-dependent manner. The activities of serum AST, ALT, TBA, TBIL and the PA content reduced.

CONCLUSIONT. wilfordii decoction shows a significant anti-immune inflammation efficacy within the dosage range between 0.59 and 2.34 g x kg(-1) in a dose-dependent manner. With a certain hepatotoxicity, high dose (2.34-4.68 g x kg(-1)) of T. wilfordii decoction can cause substantial liver injury, with a dose dependence in liver function index. Therefore, the efficacy and toxicity of T. wilfordii is dose dependent, which provides reference for preventing adverse drug reactions in clinic and developing early-warning schemes and ensure the clinical medication safety of T. wilfordii.

Objective: This study aims to investigate the correlation between the expression of FoxP3, TGF-β1, and epitheli-al-mesenchymal transition (EMT) in breast cancer and to determine the clinical significance of FoxP3. Methods: The expression of FoxP3, TGF-β1, E-Cadherin, N-Cadherin, Vimentin, and Fibronectin protein were detected in the cancer cells of 74 cases with breast carcinoma via immunohistochemistry. The correlation of FoxP3 protein with clinico-pathologic features of breast carcinoma and the re-lationships among the expressions of FoxP3, TGF-β1, and epithelial-mesenchymal transition (EMT) were analyzed. Results:The ex-pression rates of FoxP3, TGF-β1, and EMT are 36.5%(27/74), 39.2%(29/74), and 40.5%(30/74), respectively. The FoxP3 protein ex-pression in breast cancer is correlated with lymph node metastasis (P<0.05) but not with other clinico-pathological features (P>0.05). The expression of FoxP3 is also correlated with the expression of TGF-β1. Furthermore, TGF-β1 can induce EMT (P<0.05). Conclu-sion:The expression of FoxP3 is correlated with lymph node metastasis and EMT in breast cancer. Therefore, FoxP3 may be a marker for predicting metastasis.

Acetyl-CoA C-acetyltransferase (AACT) is the first enzyme in the terpene synthesis pathway, catalyzed two units of acetyl-CoA to acetoacetyl-CoA. In order to study the tanshinone biosynthesis in Salvia miltiorrhiza, a novel AACT gene, SmAACT, was cloned using cDNA microarray and RACE strategy. The full length cDNA of SmAACT is 1 623 bp (accession No. EF635969), which contained a 1 200 bp open reading frame (ORF) encoding a 399 amino acid protein. Nine introns were found in the genomic sequence. SmAACT was upregulated by YE and Ag+ elicitors both with cDNA microarray and quantitative RT-PCR analyses along with the accumulation of tanshinones. Sequence homology comparison and phylogenetic analysis all suggested that SmAACT belonged to the class of acetyl-CoA C-acetyltransferase. The transcription level of SmAACT was relatively higher in root than that in stem and leaf tissues. SNP analysis revealed that SmAACT was highly variable in the region of 6 to 9 introns with 33 SNPs in the 600 bp region, there are 5 SNPs in the cDNA region while they are all synonymous cSNPs. Some special genotypes were found in Salvia miltiorrhiza from different areas. SmAACT will be an useful gene for further analyze the mechanism of gene regulation among the tanshinones biosynthesis.
