1.Cord blood stem cells for ischemic stoke
International Journal of Cerebrovascular Diseases 2009;17(5):378-381
At present, ischemie stroke is one of the main diseases of the highest mortality and disability in the world. However, the traditional treatment methods (for example, thrombolytic therapy) have some disadvantages, such as narrow time window, and poor efficacy. As a cell therapy, cord blood stem cell transplantation has brought hope to the treatment of refractory nervous system diseases.
2.Thrombolytic strategies for acute ischemic stroke
International Journal of Cerebrovascular Diseases 2009;17(11):871-875
Thrombolytic therapy is a main treatment method for ischemic stroke.Intravenous recombinant tissue-type plasminogen activator (rtPA) is the only FDA-approved therapy for acute stroke; however,its clinical application has been limited because the narrow therapeutic time window and the presence of the risk of hemorrhagic complication.In order solve these problems,a large number of clinical trials have started to focus on the studies of intra-arterial thrombolysis,mechanical thrombolysis and sonothrombolysis.

Objective To investigate the effect of curcumin on the expression of nuclear transcription factor (NF-kappa B) and its inhibitory protein (Iκ-Bα) in liver cancer cells (Hepg-2) induced by TNF-α, and explore its effect on non-alcoholic steatohepatitis. Methods The cells were divided into normal group, TNF-alpha group, and different concentrations of curcumin treatment group. MTT and Western blotting were used to assay curcumin’s effect on Hepg-2 proliferation activity and changes of NF-κB and Iκ-Bα’s in Hepg-2. Results Compared with the normal group, TNF-αgroup enhanced NF-κB and Iκ-Bαexpression, but the increase of Iκ-Bα had no statistical significance (P>0.05). Curcumin treatment group’s NF-κB expression was significantly weakened than TNF-α group, while Iκ-Bα was significantly enhanced than that of TNF-α group. Conclusion Curcumin can antagonize NF-κB inflammatory signaling pathway activation induced by TNF-α, thus reduce the inflammatory injury of the liver cells.

Objective To investigate the ultrasonic features and pathological basis of follicular variant of papillary thyroid carcinoma (FVPTC). Methods Ultrasonic presentation of 30 patients with FVPTC conifrmed by surgery and pathology from the Seventh People′s Hospital of Shaoxing during March 2002 and December 2012 were analyzed retrospectively and compared with pathological results. Results Ultrasonic presentation of 30 FVPTC cases could be classiifed into three types:(1) Six cases (20%, 6/30) of typeⅠ, with typical sonographic features of papillary thyroid carcinoma:nodules with irregular shape, unclear boundary, and very low echo inside, microcalciifcation could be seen. (2) Fourteen cases (47%,14/30) of typeⅡ, presented as clearer iso-echoic or hypo-echoic nodules, with irregular shape, angled and lobular edge, rare microcalciifcation. (3) Ten cases (33%, 10/30) of typeⅢ, presented as adenoma-like features, nodule with clear boundary and regular edge, uniform medium echo inside. The microscopic structure characteristics could be divided into three categories:6 cases of typeⅠ, lesions were featured with no obvious capsule, irregular shape and inifltrative growth;14 cases of type Ⅱ, lesions with irregular shape, which invading the capsule with partial protrusion and peripheral small satellite lesions;10 cases of typeⅢ, lesions with more complete envelope, more regular shape with no signiifcant or lower level and smaller extent invasion of the capsule. Differences in morphology, boundary, aspect ratio, internal echo, presentation of microcalciifcations between the encapsulated type (typeⅡ,Ⅲ) and non-encapsulated type (typeⅠ) FVPTC were statistically signiifcant (Fisher′s exact test, all P<0.05). While the difference in lymph nodes involvement between them was not statistically signiifcant (Fisher′s exact test, both P>0.05). Conclusion Ultrasonic presentation of FVPTC show characteristics of both follicular tumor and papillary carcinoma, and the ultrasonic presentations are closely related to the pathological subtypes.

Objective To investigate the risk factors of wound healing 30 days after treatment in patients with pressure ulcer. Methods Two hundred and forty-five hospitalized patients with pressure ulcer between January 2015 and October 2016 were selected. They were divided into the healed group and the unhealed group 30 days after the treatment. The influencing factors 13 indexes including age, gender, edema, the number of diseases, the number of pressure ulcer, the size of pressure ulcer, PUSH score (Pressure Ulcer Scale Healing), hemoglobin, serum albumin, low density lipoprotein cholesterol and blood homocysteine underwent single factor and Logistic regression analysis. Results Single factor analysis of 12 indicators of risk factors affecting healing were age, Hb, Alb, Hcy, area of ulcer and PUSH scores of the 6 indicators in the regression equation (Z=3.11-6.63, All P < 0.01), gender also entered the regression equation (χ2=0.19, P<0.01);further multivariate regression analysis showed that there were statistically significant differences in PUSH score index (χ2=10.47, P<0.01, OR=0.001, 95%confidence interval were 0.001-0.037). Conclusions Age, gender, Hb, Alb, Hcy and PU area were the risk factors of pressure ulcer healing.

Protein transduction is an emerging technique in biological fields in recent years. Through the medium of protein transduction domain(PTD) composed by a small number of alkaline peptides, the functional proteins linked covalently with DNA, peptides, proteins or other macromolecules can across the membranes of mammalian cells, even the blood-brain barrier and transfer unconventionally that isn't like classical pathway. The distinct property of PTD that can take along fused protein entering into cells unconventionally offers a new vehicle to gene therapy for some diseases and has dulcet applied perspective.

Objective To detect the effects of miR-143 on proliferation, migration and invasion of human nasopharyngeal cancer CNE-2Z cells.Methods The expression of miR-143 in NP69 cells, CNE-1 cells and CNE-2Z cells were detected by using real-time PCR.The overexpression of miR-143 in CNE-2Z cells was constructed through infecting lentivrius, and the level of miR-143 was determined by using real-time PCR.Cell viability was detected by using a CCK-8 kit according to the manufacturer's instruction at indicated time points.The effectiveness of overex-pression of miR-143 on migration and invasion of CNE-2Z cells were detected by using Transwell cell migration and invasion assay.Results The expression level of miR-143 in CNE-2Z was significantly lower than those in NP69 and CNE-1 (P<0.01).The miR-143 over-expressed CNE-2Z cell was successfully established.The cell viability in CNE-2Z/ miR-143 group was significantly decreased compared with CNE-2Z and CNE-2Z/miR-NC (P<0.01).Overexpression of miR-143 inhibited cell migration and invasion of CNE-2Z cells significantly(P<0.01).Conclusion miR-143 might inhibit cell proliferation, migration and invasion in human nasopharyngeal cancer CNE-2Z cells, indicating its important role in diagnosis, treatment and prognosis of nasopharyngeal cancer.

Objective To investigate the HBV- positive pregnant women about the knowledge of the route of hepatitis B transmission, hepatitis B hazards, health care during pregnancy, announcements of child- care to explore targeted and effective health education model with self- designed question-naires. Methods Nurses in obstetrics department carried out this questionnaire investigation in the outpa-tients of HBV- positive pregnant women, after that the results underwent statistic analysis. Results The overall knowledge of HBV- positive pregnant women in announcements of child- care, health care during pregnancy and hepatitis B hazards was not very well, and the announcements of child- care was the lowest, followed by health care during pregnancy and hepatitis B hazards. The route of hepatitis B transmission was better, but still not satisfactory. The education should highlight these areas. Well- educated women were better than those who lack education. The age between 20 to 30 years old was better. Conclusions The HBV-positive pregnant women is lack of heath knowledge, so we should gave health intervention in a multi- level, multi- stage standardized and a variety of ways.
