Objective To analyze the correlative factors of anemia in patients with non-small-cell lung cancer (NSCLC), and to explore the impact of anemia on prognosis.Methods The clinical data of 473 patients with NSCLC treated at the first time from January 2008 to November 2012 in the Fourth Hospital of Hebei Medical University were analyzed retrospectively.Results There were 273 patients (57.72 ％) with anemia.Anemia occurred in different age (x2 =3.459, P =3.459), different albumin level (x2 =70.648, P =70.648), different PS score (x2 =10.222, P =10.222), whether recent surgery (x2 =4.956, P =4.956), whether recent chemotherapy (x2 =3.627, P =0.037), and other factors.By multiple factors analysis, hypoalbuminemia was an independent risk factor for anemia (P ＜ 0.05).The median OS of the anemia patients was shorter than that of the patients without anemia (15 months vs 17 months, P ＜ 0.05).Conclusions Hypoalbuminemia is the independent risk factor for emergence of anemia.Anemia is the prognosis indicator of shorten survival period, which is an independent factor of prognosis in the NSCLC.

Objective To study the changes of portal vein pressure before and after interventional embolization with α-cyanoacrylate alkyl and their clinical significance. Methods Thirty five patients with esophageal-gastric variceal bleeding were included. Esophageal-gastric fundal varices were embolized with e-cyanoacrylate alkyl in 35 patients, and 10 of them were treated with combination of partial splenic emblization. Portal pressure was measured directly before and after interventional embolization. The patients were followed up for 3-18 months. The changes of the liver functions and complications after the embolization were observed. Results All bleeding were controlled successfully. The main portal pressure in those who received variceal embolization only increased significantly from (32.54±5.23) cm H2O (1 cm H2O=0. 098 kPa) to (37.45±5. 11) cm H2O; superior mesenteric vein pressure increased from (31.46±4.35) cmH2O to (34.33±4.68)cm H2O; and the level of serum albumin raised from (30.45±5.78) g/L to (34.57±6.84) g/L 3 weeks after embolization. Whereas the main portal pressure in those who received both variceal and partial splenic embolizations, decreased significantly from (32. 68±4. 89) cm H2O to (28. 70±4. 58) cm H2O; superior mesenteric vein pressure decreased from (31.46±4.35) cm H2O to (28.03±4.12) cm H2O; and splenic vein pressure decreased from (32.89±4.79) cm H2O to (28.81±5. 12) cm H2O.Conclusions Esophageal-gastric variceal embolization is effective for varieeal bleeding. The increase of main portal pressure after embolization may be benefit for liver function, while the rise of superior mesenteric vein pressure may increase the risk of portal hypertensive gastrointestinal re-bleeding.Esophageal-gastric variceal embolization combined with partial splenic embolization may reduce the incidence of portal hypertension and gastrointestinal re-bleeding, but will increase the risk of ascites.

AIM: To investigate the effect of FAK - related non - kinase ( FRNK) on the expression of membrane - type matrix metalloproteinase -1 ( MT1 - MMP) in hepatic stellate cells ( HSC). METHODS:FRNK were trans-fected into HSCs by cationic liposome method. The protein levels of FRNK in HSC were assayed by Western blotting. The levels of MT1 - MMP were determined by RT - PCR for mRNA and by Western blotting for protein, respectively. RESULTS: The up -regulated expression of FRNK protein was observed and it was at 48 h after transfection that the FRNK protein content was the highest ( P < 0.05 ). The expressions of MT1 - MMP mRNA and protein were also up - regulated by the transfection of FRNK, and it was at 48 h after transfection that the MT1 - MMP protein content was significantly increased. CONCLUSION: The mRNA and protein of FRNK were over - expressed in HSC transfected with the gene of FRNK. The inhibitory effect of FRNK on the collagen synthesis in HSC may be through the up - regulation of MT1 - MMP.
