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.

Objective:To improve the diagnosis and treatment of thyroid carcinoma in flying personnel by analyzing the clinical characteristics of thyroid carcinoma.Methods:The clinical and pathological data of flying personnel with thyroid carcinoma diagnosed and treated by Air Force Medical Center of PLA from January of 2010 to December of 2022 were retrospectively analyzed. Clinical characteristics such as age, flying hours, aircraft types, thyroid function at diagnosis, and pathological characteristics such as tumor site, tumor size, lymph node metastasis, calcification and sand and Ki-67 positive ratio were collected, and the clinical and pathological characteristics were statistically analyzed.Results:Thyroid nodule was found as the first diagnosis of thyroid carcinoma in 57 flying personnel. The age of onset was 22-58 years old, the median age was 37 years old, the flying hours was 4-18 000 h, and the median flying hours was 2 000 h. Thyroid carcinoma was detected in both thyroid glands, and the histological type was papillary thyroid carcinoma. Thyroid function was normal in most cases when thyroid carcinoma was detected. Lymph node metastasis of thyroid carcinoma was low positively correlated with tumor size ( r=0.304, P=0.021), and was low positively correlated with the positive proportion of Ki-67 ( r=0.360, P=0.006). Other clinical and pathological characteristics did not show clear correlation. With the extension of flying hours, the incidence of lymph node metastasis of thyroid carcinoma increased, and the difference was statistically significant ( χ2=6.32, P=0.012). There was no statistical difference among the clinical characteristics of flying personnel with different age and aircraft types ( P>0.05). Conclusions:The thyroid carcinoma is usually diagnosed without clinical symptoms and the thyroid function is basically normal. The thyroid ultrasound examination should be emphasized during physical examination, and further examination should be conducted for the flying personnel with thyroid nodules.
