Methods The model rats were established by being injected its blood to its own basal segmental, which induced cerebral bleeding. Bc1-2 was determined with immunohistochemical method and was used to evaluate the effect of Yugong Qili Duoming Capsule on the treatment group and other comparative group. Results The Bc1-2 cells in brain issue of model groups began to increase at the 1st day, reached its highest level at the 2nd day and decreased greatly at the 7th day. However, the Bcl-2 cells of the treatment group were much more than those of the model groups in the 2nd, 4th and 7th day. Conclusion Yugong Qili Duoming Capsule can increase expression of Bc1-2 in brain tissue of cerebral bleeding model rats.

BACKGROUND:Avulsion fractures of the tibial attachment of the posterior cruciate ligament have been repaired using open reduction and rivet fixation, hol ow screw fixation, or arthroscopic reconstruction of the posterior cruciate ligament. These methods ignore the importance of early tension reconstruction of the posterior cruciate ligament, so their efficacies are uncertain. Determining the optimal fixation method and how best to restore knee stability remain controversial. OBJECTIVE:To observe the stability of new bone fixation plate for the repair of avulsion fracture of the tibial attachment of the posterior cruciate ligament. METHODS/DESIGN:We wil conduct a prospective, single-center, self-control ed, clinical trial at the Cangzhou Central Hospital, Hebei Province, China. Fracture fragments and the injured posterior cruciate ligament wil be exposed in 20 patients with avulsion fracture of the tibial attachment of the posterior cruciate ligament through a posterior approach and open reduction. The posterior cruciate ligament wil be reconstructed with a new type of bone plate. Al patients wil be fol owed for 3 and 12 months. Primary outcome:The Hospital for Special Surgery knee score wil be used to evaluate knee function preoperatively and 3 and 12 months postoperatively. Secondary outcomes:Lysholm Knee Scoring Scale, X-ray, computed tomography, and magnetic resonance imaging wil be used to assess knee morphology preoperatively and 3 and 12 months postoperatively. Patient satisfaction wil also be assessed at 3 and 12 months postoperatively. The study protaol was registered at clinicaltrials.gov.NCT03059368. The study protocol has been approved by the Ethics Committee of Cangzhou Central Hospital of China. Al protocols wil be conducted in accordance with Declaration of Helsinki, formulated by the World Medical Association. Written informed consent wil be provided by al participants. DISCUSSION:This trial wil evaluate a newly-designed plate fixation device for early tension reconstruction of the posterior cruciate ligament to repair avulsion fractures of the tibial attachment of the posterior cruciate ligament and restore knee stability. This trial wil verify the plate's efficacy, provide an experimental basis for treating avulsion fractures of the tibial attachment of the posterior cruciate ligament, and provide a method of maximizing knee stability.

Objective To investigate the expressions of cancerous inhibitor of protein phosphatase 2A (CIP2A) and vascular endothelial growth factor (VEGF) in hepatocellular carcinomas and their clinical significance.Methods The expressions of CIP2A and VEGF proteins were tested with immunohistochemistry in 60 cases of hepatocellular carcinomas and adjacent paracancerous tissues.Results The positive rate of CIP2A in hepatocellular carcinomas was significantly higher than adjacent paracancerous tissues (83.3％ vs 9.5％,P ＜ 0.05).Significant differences were also observed in the expression rate of VEGF between the patients with hepatocellular carcinomas and paracancerous tissues (75.0％ vs 14.3％,P ＜0.05).The expression of CIP2A in hepatocellular carcinomas was significantly positively correlated with its pathological grading,differentiation,and tumor node metastasis (TNM) stage (P ＜ 0.05).The expression of VEGF in hepatocellular carcinomas was significantly positively correlated with its pathological grading,differentiation,and TNM stage (P ＜ 0.05).Significantly positive correlation was found between expressions of CIP2A and VEGF with Spearman correlation analysis (rs =0.465,P ＜ 0.01).Conclusions The abnormal expressions of CIP2A and VEGF gene may promote tumor angiogenesis and progression of a hepatocellular carcinoma.The study supports positive regulation between expressions of CIP2A and VEGF in a hepatocellular carcinoma.

Objective To investigate the expressions of phosphatidylinositol 3-kinase (PI3K), Akt and E-cadherin and their clinical significance in thyroid papillary carcinomas.Methods Expressions of PI3K, Akt, and E-cadherin were detected in 62 cases of thyroid papillary carcinomas,30 cases of thyroid goiter and 30 cases of normal thyroid by immunohistochemistry (EnVison),and simultaneously compared with age, sex, tumor size, clinical tumor node metastasis( TNM) stages, and lymph node metastasis in thy-roid papillary carcinomas.Results The expression rate of PI3K, Akt, and E-cadherin was 74.2%(46/62), 66.1%(41/62), 16.1%(10/62),respectively.Expressions of three proteins in thyroid papillary carcinomas were significantly different from those in thyroid goiter and normal thyroid tissues ( P <0.05). The lower positive rates of PI3K and Akt proteins were obtained in the group of stageⅠ~Ⅱthan that in the group of stageⅢ~Ⅳ(χ2 =4.976, P =0.026;χ2 =6.233, P =0.013).Higher positive rates of PI3K and Akt proteins were obtained in the group of lymph-node metastasis than that in group of non-lymph-node metastasis (χ2 =6.675, P =0.010;χ2 =7.511, P =0.006).Higher positive rate of E-cadherin protein was obtained in the group of stage Ⅰ~Ⅱ than that in the group of stage Ⅲ ~Ⅳ (χ2 =6.558, P =0.010 ) .Higher positive rate of E-cadherin proteins was obtained in the group of non-lymph-node metastasis than that in the group of lymph node metastasis(χ2 =5.678, P =0.017).There was significant positive correlation between expressions of PI3K and Akt through Spearman correlation analysis ( r =0.423, P <0.05).PI3K was negatively correlated with E-cadherin with Spearman correlation analysis ( r =-0.527, P <0.05).Akt was also negatively correlated with E-cadherin ( r =-0.417, P <0.05).Conclusions PI3K/Akt pathway might regulate thyroid papillary carcinoma cells proliferation, invasion and metastasis.
