P2RX7 functions as a putative biomarker of gastric cancer and contributes to worse prognosis.

IMPACT STATEMENT: The mechanism of gastric cancer is highly complex, accompanied by a variety of genetic abnormalities. It is of great significance to elucidate the pathogenesis of gastric cancer, find its markers and therapeutic targets in the fight against this fatal disease. In this study, we identified P2RX7 as a putative target of gastric cancer, which was overexpressed in gastric cancer tissues and had relationship with worse prognosis. We also elucidated the roles of P2RX7 on the growth and metastasis of gastric cancer cells, and explored the relationship between it and ERK1/2 pathway, Akt pathway, and epithelial-mesenchymal transition. Our findings begin to offer useful insights into the mechanism of gastric cancer progression and provide clues to novel therapy strategies.

Minor liver resection for hilar cholangiocarcinoma of Bismuth-Corlette type Ⅲ and Ⅳ / 中华外科杂志

Objective@#To explore the clinical effect and safety of minor liver resection for hilar cholangiocarcinoma (HC) of Bismuth-Corlette type Ⅲ and Ⅳ.@*Methods@#From May 2007 to May 2017, the clinical data of 108 patients with Bismuth-Corlette type Ⅲ and Ⅳ HC underwent hepatectomy were collected and analyzed retrospectively.There were 56 males and 52 females, aged (57.2±5.3) years (ranged 48-76 years) .Among the 108 cases, there were 51 cases of type Ⅲa, 40 cases of type Ⅲb and 17 cases of type Ⅳ. Small-scale hepatectomy (≤3 hepatectomy) was performed in 70 cases, including 8 cases of 4b segment resection, 28 cases of 4b segment+5 segment resection, and 34 cases of partial 4 segment+partial 7 segment+partial 1 segment resection. Large-scale hepatectomy was performed in 38 cases (>3 segments) , of which 30 cases were treated with 2 segments+3 segments+4 segments+1 segment, and 8 cases were treated with 5 segments+7 segments+8 segments+1 segment. t′ test was used to analyze the data which did not conform to the normal distribution, and χ2 test was used to calculate the incidence of postoperative complications and the 1, 3, and 5-year cumulative overall survival rate.@*Results@#(1) The operation time of minor liver resection group ((180±25)minutes) was shorter than that of major liver resection group ((210±35)minutes) (t′=4.676, P<0.05) , the amount of blooding operation time of minor liver resection group ((310±80)ml) was less than that of major liver resection group ((500±110)ml)in the operation (t′=9.385, P<0.05) , and the difference was statistically significant. (2) The incidence of complications was lower in minor liver resection group and major liver resection group, and the difference was statistically significant (χ2=5.230, P<0.05) . (3) The actual 1-, 3- and 5-year survival rates were 87.1%, 58.4%, 30.0% and 84.2%, 57.9%,31.6%, respectively. There were no significant differences in survival rates in two groups in 1-, 3- and 5-year survival rates (χ2=0.177, P=0.674; χ2=0.005, P=0.946; χ2=0.029, P=0.865) .@*Conclusions@#Compared to patients with major liver resection, Minor liver resection for selected patients with HC of Bismuth-Corlette Ⅲ and Ⅳaccording to our criteria achieved better long-term outcomes. Chen′s biliojejunostomy is a simple, effective and safe method, which can be widely used when there are multiple biliary intestinal anastomosese.

Perioperative nursing of patients undergoing radical prostatectomy of endometrial cancer with DaVinci Robot / 现代临床护理

Objective To summarize the nursing points of 30 patients undergoing radical prostatectomy of endometrial cancer with DaVinci Robot.Method The clinical histories of patients undergoing radical prostatectomy of endometrial cancer with DaVinci Robot from May 2010 to April 2014 in the Second Artillery General Hospital of Chinese People’s Liberation Army were analyzed retrospectively.Result All 30 patients were discharged successfully with 2 postoperative uroschesis,1 lower extremity varicose veins,10 subcutaneous emphysema.Conclusion Perfect preoperative nursing is the guarantee for the success of radical prostatectomy of endometrial cancer with DaVinci Robot.

On the expression of cytokine in monocyte by intermittent high glucose / 中华内分泌代谢杂志

The mechanism of damage in monocytes with the oxidation inhibitor α-lipoic acid (ALA) was observed under intermittent high glucose condition.The results showed that fluctuating high blood glucose levels led to more damage than that under constant high blood glucose level in monocyte,and antioxidant α-ALA could ameliorate the oxidative stress.The high level of nuclear factor-κB and monocyte chemotactic protein-1 are probably among the factors that cause vascular damage by deposit of monocytes.
