Objective To study the changes of liver blood flow with or without portal vein thrombus (PVTT) in hepatocellular carcinoma. Methods The hepatocellular carcinoma patients with PVTT (n=26) and without PVTT (n=35) were enrolled. The diameter and the velocity of hepatic arterial (HA) and portal vein (PV) were measured with color Doppler flow imaging in all patients. Results In the patients with PVTT, the diameter of PV dilated and the velocity of PV dropped significantly and the velocity of HA rised obviously, as compared with those without PVTT. Conclusion The index of HA and PA is very important to guide the therapy of hepatocellular carcinoma.

Objective:To explore the effect of emotional stress to the intra-islet apoptosis and the it's neural mechanism.Methods: Using the drinking-conflict stress and restraint stress, we investigated diabetes-prone NOD mouse's c-fos expression in it's brain and it's intra-islet apoptosis. Correlation between the two variables was also studied.Results:The average intra-islet apoptosis of the first(3.95?1.05)and the second (5.73?2.60)and third day(5.77?2.75) was higher than the control's(0.82?0.93,P

Epidermal growth factor receptor (EGFR), a member of the super family of protein tyrosine kinase receptors, plays a crucial role in proliferation, apoptosis, aggression and metastasis of tumor cells. The target-EGFR inhibitors have been a hotspot and tendency in the progress of anti-tumors. Currently, the target-EGFR inhibitors have made a steady progress and many valuable drugs in the clinical treatment have been developed. However, many patients will be resistance to the drugs due to the mutation of amino acid. Therefore, drugs which can be effective in the later treatment or long-term therapies will always be deficient. In this article, the research progress and mechanism of anti-tumor of small molecules EGFR inhibitors in detail are reviewed.

Objective:To investigate the mechanism of liver and lung injury in mouse septic models.Methods:Twenty-four male Kunming mice were subjected to cecal ligation and puncture(CLP)or sham operation.The permeability of microvasculature,water contents,activities of myeloperoxidase(MPO)and the apoptosis of microvascular endothelial cells in lung microvasculature and liver sinus were examined 3 h and 12 h after operation.Results:Both the liver and lung showed a significant increase in microvessel permeability at 12 h in CLP group compared with sham operation group.MPO activity and water content in CLP group were obviously higher than those in the sham operation group.The apoptosis of lung microvascular endothelial cells at 12 h in CLP group(5.03?0.92)% was significantly higher than that of control group(3.48?1.21)%(P

AlM:To analyze and compare the effect of femtosecond laser micro - incision corneal stromal lens excision ( SMlLE) and excimer laser in situ keratomileusis ( LASlK) in the treatment of myopia after operation, to explore the safety, operability and prediction of SMlLE.METHODS:ln this prospective clinical controlled study, 100 cases ( 200 eyes ) received SMlLE and 100 cases ( 200 eyes) undergone LASl in our hospital in the same period were selected. Uncorrected visual acuity, diopter, corrected visual acuity, slit lamp examination, intraocular pressure and corneal anterior segment OCT, corneal topography (Obscan ll) of two groups in 1d, 1wk, 1, 3, 6mo, 1a were compared. lndependent samples t test was used for data analysis.RESULTS:1) Postoperative slit lamp examination:after 1d in SMlLE group, there were less eyes had corneal layer between mild cloudy or edema; postoperative 1wk corneal layer disappeared, cornea became clear and transparent. 2 ) Postoperative vision recovery: 1d after operation, vision recovery in LASlK group was better than that in SMlLE group, the difference was statistically significant (P<0. 01), there were no significant differences at 1wk, 1, 3, 6mo, 1a after operation ( P>0. 05 ). 3 ) Obscan ll examination: graphics in the SMlLE group was more regular and placed in the center, no eccentric and irregular graphics, better than that in the LASlK group. 4) Anterior segment OCT examination:postoperative corneal flap in the SMlLE group was more uniform and accurate, but it was thin in the center and slightly thick the peripheral part in the LASlK groups. 5 ) Postoperative visual quality assessment used subjective questionnaire survey. The two groups had statistically significant difference on 4 points and 1 points (P<0. 05). Complains in the LASlK groups were more that that in the SMlLE group. While, no complain of the SMlLE group was higher than that of the LASlK group. Glare of postoperative patients with night vision and dark environment in the SMlLE group was better than that of the LASlK group.CONCLUSlON: SMlLE is safe, effective, stable and predictable for the correction of myopia.
