Objective To evaluate the prognostic significance of carbonic anhydrase IX (CA IX) expression in patients with clear cell renal cell carcinoma (ccRCC). Methods CA IX expression in a cohort of 120 patients with ccRCC was evaluated by P-V immunohistochemistry with a rabbit CA IX polyclonal antibody. Twenty-five normal kidney tissues were used as a control. The relationship between CA IX expression and prognosis was analyzed by univariate and multiple-factor analysis (Cox regression model). The primary end point was cancer specific survival. Results One hundred and twelve (93.3%) patients were followed up with the median follow-up time of 45 months (range, 6 to 94 months). Seventy-five patients survived without evidence of tumor recurrence, 3 patients survived with tumor recurrence, and 34 patients died, 28 of the 34 died of cancer. CA IX expression was negative in all normal renal tissue. High CA IX expression was observed in 89 (74.2%) patients, among which 82 patients were followed up, and the disease free survival was 75.6% (62/82). Two (2.4%) patients survived with tumor recurrence, and 18 (22.0%) patients died, of which 13 (15.9%) died of cancer. Tumor recurrence and (or) metastasis occurred in 9 (11.0%) patients, with a median survival of 92 months in this high expression group. Low CA IX expression was observed in 31 (25.8%) patients, among which 30 patients were followed up, and the disease free survival was 43.3% (13/30). One (3.3%) patient survived with tumor recurrence, and 16 (53.3%) patients died, of which 15 (50.0%) died of cancer. Tumor recurrence and (or) metastasis occurred in 8 (26.7%) patients with a median survival of 53 months in this low expression group. Cancer specific survival between CA IX high expression group and low expression group was significantly different (P=0.000, χ2=15.950), and tumor relapse and (or) metastasis rates were significantly different (P=0.040, χ2=4.200). The 1, 3, 5 and 7 year cancer specific survival rates were 95.2%, 83.9%, 81.2% and 78.2% respectively in the high CA IX expression group, and 89.5%, 63.9%, 46.8% and 40.1% respectively in the low expression group. Multivariate analysis with Cox regression model showed that CA IX expression was a prognostic factor (RR=0.186). Conclusions High CA IX expression is negatively correlated with postoperative mortality, relapse and (or) metastasis in ccRCC. CA IX expression could be used as a prognostic biomarker in ccRCC.

The porous scaffolds for bone tissue engineering were prepared by foam impregnation. The magnesium and aluminum acid phosphates were used as bonder and the hydroxyapatite ((Ca10 (PO4)6(OH)2, HA) powder as raw materials. Scanning electron microscopy (SEM) examination indicated that the 3D interconnected porous structure of the organic foam was replicated well by the scaffolds calcined at high temperature and the structural requirement of tissue engineering was satisfied. XRD analysis showed that the scaffold was composed of HA and Ca7Mg2P6O24 while calcined at 1150 degrees C for shorter time and of (Ca, Mg)3(PO4)2 when the time prolonged to 2 h. There was no peak of CaO found in the scaffolds by XRD. According to the culture in vitro, the scaffold possesses good biocompatibility and certain degree of degradability.

Objective:
To improve the diagnosis and treatment of primary adrenal cortical carcinoma.
Methods:
The clinical and pathological data of 11 patients who diagnosed as primary adrenal cortical carcinoma by pathology were retrospectively analyzed.The median age was 43 years, including 6 males, 5 females.7 cases(63.6%) got the tumor on the left.9 cases(81.8%) presented the maximum diameter of tumor more than 6 cm, and the average maximum diameter was 12.9 cm.All cases had CT or MRI imaging examination.Among most of them, CT showed mixed density lesions, or MRI showed mixed signal.Only 3 cases(27.3%) were considered adrenal cortical cancer through preoperative examinations.
Results:
11 patients were treated with surgical treatment.Of them, 9 cases(81.8%) had complete resection of tumor.3 cases were lost to follow-up, while other 8 cases were followed up for 5-58 months.3 cases presented tumor-specific death at 5-15 months after surgery, with each 1 case in AJCC stage Ⅱ, Ⅲ and Ⅳ, respectively.Survive were in 5cases, and 3cases of them were tumor-free survival, while the other 2 cases of them had local recurrence.
Conclusion
Adrenal cortical carcinoma is very difficult to diagnose preoperatively.Adrenal cortical cancer should be considered when tumor size more than 4cm and tumor presenting inhomogeneous enhancement.Then, the surgical treatment should be performed as soon as possible, and as appropriate, chemotherapy and other comprehensive treatment should be given subsequently.Clinical and basic research such as genes test may provide more treatment options for advanced tumors in future.
