Objective : To explore the expression of prohibitin2(PHB2) in breast cancer and its effect on the biological behaviors of tumor cells. Methods : Immunohistochemistry was used to detect the expression of PHB2 protein in breast cancer tissues and its relationship with clinicopathologic features. Breast cancer stable transient cell lines were constructed with knockdown and overexpression ofPHB2, respectively. The effects of PHB2 on cell proliferation, migration and invasion ability were detected by clone formation assay, scratch assay and Transwell assay. Western blot(WB) was used to detect the effects of PHB2 on the expression of epithelial-mesenchymal transition(EMT)-related markers, including E-cadherin, N-cadherin, Snail family transcriptional repressor 1(Snail) protein, Vimentin, and Claudin-1. The effect of PHB2 on tumorigenicityin vivowas detected by subcutaneous tumor formation assay in nude mice. Results: The result of immunohistochemical showed that PHB2 was highly expressed in breast cancer and the expression of PHB2 was significantly positive correlated with tumor size, human epidermal growth factor receptor-2(HER-2) status and proliferation index Ki-67 levels(P<0.05). Clone formation assay, scratch assay and Transwell assay revealed that knockdown ofPBH2significantly inhibited the proliferation, migration and invasion ability of breast cancer cells(P<0.01), while the overexpression ofPHB2significantly promoted cell proliferation, migration and invasion(P<0.01). The result of subcutaneous tumor formation experiment in nude mice revealed a significant decrease in tumor volume and weight in knockdownPHB2mice(P<0.000 1), whilePHB2overexpression tumors significantly increased in volume and weight(P<0.001).WB assay showed that the protein expression of epithelial marker E-cadherin increased, while the expressions of mesenchymal markers N-cadherin, Snail and Vimentin decreased significantly afterPHB2knockdown with them in control cells(P<0.01). The expression of Claudin-1 decreased, while the expressions of N-cadherin, Snail and Vimentin increased significantly inPHB2overexpression cells(P<0.05). Conclusion PHB2 is highly expressed in breast cancer and promotes multiple malignant biological behaviors in tumor cells, suggesting PHB2 may be a potential target for breast cancer diagnosis and treatment.

Objective : To explore the role and mechanism of plasmalemma vesicle-associated protein(PLVAP) in the progression of hepatocellular carcinoma(HCC). Methods : Bioinformatic analysis, quantitative real-time PCR, Western blot and immunohistochemistry were used to analyze the expression level of PLVAP in HCC and paracancerous tissues, and its correlation with clinicopathological characteristics. Stable HCC cell lines with knockdown and overexpression of PLVAP were constructed, then cell proliferation, migration and invasion of HCC cells were examined by CCK-8, foci formation assays, wound-healing assays and Transwell assays. Western blot was used to detect the protein levels of phosphatidylinositol 3-kinase PI3K, phosphorylated phosphatidylinositol 3-kinase p-PI3K, protein kinase B AKT and phosphorylated protein kinase B p-AKT in the PI3K/AKT pathway after PLVAP knockdown and overexpression. Cell proliferation, migration and invasion were also examined in PLVAP-overexpressed cells after treatment of LY294002, an inhibitor of the PI3K/AKT pathway. Results : The expression of PLVAP was significantly higher in HCC tissues than that in adjacent non-tumor tissues(P<0.05), and was positive correlated with tumor stage, T stage, M stage, and microvascular invasion(P<0.05). Knockdown of PLVAP significantly reduced the proliferation, migration and invasion of HCC cells(P<0.001), while overexpression of PLVAP significantly increased the proliferation, migration and invasion of HCC cells(P<0.01). Western blot analysis revealed that knockdown of PLVAP decreased the protein expression levels of p-PI3K and p-AKT, overexpression of PLVAP increased the protein expression levels of p-PI3K and p-AKT, whereas the PI3K/AKT inhibitor LY294002 eliminated the effects of PLVAP on cell proliferation, migration and invasion(P<0.01). Conclusion PLVAP is highly expressed in HCC and may promote HCC progression by activating the PI3K/AKT signaling pathway.

In view of the high recognition error rate and long scanning time in the existing hospital scanning technology, a new hospital operating room scanning system is designed based on personal digital assistant (PDA). The PDA scanning device adopts PIC16F877A microcontroller of 8 bit for wireless transmission through RFID and bluetooth technology, the code scanning efficiency is greatly improved. In addition, in order to improve the accuracy of image analysis, this study also adopts the energy driven sampling classification algorithm (EDS-CA) to properly preprocess the medical data information received through PDA scanning, then constructs a function classifier, and improves the image processing efficiency according to the EDS-CA reduction process. The experimental results show that the average accuracy of the code scanning system designed in this study is 95%, which proves that PDA code scanning has good performance.

Objective To explore the clinical effect of conventional surgical treatment of tibial plateau fractures and traditional Chinese medicine intervention. Methods Sixty-eight patients with tibial plateau fractures who had received medical treatment from Hangzhou Cancer Hospital (May 23, 2015 to May 23, 2016) were randomized to the surgical group and the combined group as the subjects of this study. 34 patients in the operation group were treated with surgical treatment. 34 patients in the combined group were treated with traditional Chinese medicine on the basis of operation. The clinical efficacy and knee function scores of the patients with tibial plateau fractures were compared. Results The total effective rate was 91.18% in the combined group, which was significantly higher than that in the operation group (73.53%) (P<0.05). The knee function score of the combined group was (25.36±3.85) The operation group (21.24 ± 3.89) was significantly higher (P<0.05). Conclusion The intervention of traditional Chinese medicine combined with traditional Chinese medicine can significantly improve the function of knee joint in patients with tibial plateau fractures.

Objective To observe the influences of Shendan Sanjie capsule on chemotherapy effect and immune index to patients with advanced non-small cell lung cancer.MethodsDividing 76 patients with advanced non-small cell lung cancer from department of oncology from January 2014 to May 2016,each with 38 cases.The control group recei-ved western chemotherapy,observation group received western chemotherapy with Shendan Sanjie capsule.The differences of related indicators were compared.Results①After chem-otherapy,in the control group, CD4+decreased,CD8+ increased and CD4+/CD8+ decreased,and before chemotherapy, the difference was significant(P<0.05).In observation group,there was no significant difference in CD4+, CD8+, CD4+ / CD8+ levels.The above indicators of observation group were better than that of control group.②After chemotherapy,RR(CR+PR)rate of observation group were 57.89%, higher than the control group with 36.84%(P<0.05).③During chemotherapy,toxic side effect ratio of observation group was lower than that of the control group(P<0.05).ConclusionComparing Shen Dan Sanjie capsule can adjust patient immunity and reduce side effects of chemotherapy during chemotherapy.
