Transcatheter arterial chemoembolization (TACE) is the first choice of patients with hepatocellular carcinoma (HCC) missed opportunity of exairesis.Angiogenesis is one of the key factors that affect prospective efficacy.Counter-measures against angiogenesis mainly contain complete embolization of tumor blood supply and integration with angiogenesis inhibitors.The angiogenesis after TACE and the corresponding countermeasures were reviewed in this article.

Objective To investigate the effect and its mechanism of cyclin dependent protein kinase inhibitor Olomoucine treatment on experimental herpes simplex encephalitis(HSE). Methods 45 mice were randomly assigned to HSV-1 sham-infected group (n=15), HSV-1 infected control group (n=15) and Olomoucine treated group (n=15). Flow cytometry was used to detect the expression of brain cells surface antigen CD11b. The reverse transcription polymerase chain reaction (RT-PCR) to detect the expression of tumor necrosis factor-? (TNF-?) and Interleukin-6 (IL-6). TUNEL method was adopted to detect neural cells apoptosis. Pathologic slices of brain tissues were used to identify tissue morphology differences. The survival rates were compared between the treatment groups Acyclovir (n=20) and Olomoucine (n=20) by the method of Kaplan-Meier 2 weeks after HSV-1 infection. Results After HSV-1 infection, the expression of brain tissue CD11b, TNF-?, IL-6 were significantly increased compared with sham-infected group (allP

AIM To investigate the effect of clonidine on intraocular pressure(IOP) and the possible role in which ? adrenergic mechanism plays. METHODS The change on IOP was observed following clonidine administered via three different routes: (1)clonidine topically administered to eyes; (2)clonidine intracerebroventricularly injected (icv)or topically administered after yohimbine or prazosin icv; (3)microinjection of clonidine into locus coeruleus(LC). RESULTS Clonidine decreased IOP significantly, ? 2 adrenoceptor antagonist, but not ? 1 adrenoceptor antagonist, can reverse the decreasing effect on IOP caused by clonidine icv and administered topically. CONCLUSION Clonidine administered both topically or intracranially can decrease IOP;? 2 adrenoceptor in central nervous system is involved in this effect.

Objective To evaluate and compare the clinical outcomes of concurrent chemoradiotherapy with different radiation doses for esophageal carcinoma. Methods 78 cases of esophageal carcinoma receiving primary definitive treatment in our department between May 1 , 2005 to June 31 2007 were analyzed retrospectively. The patients with esophageal carcinoma were divided into high- ( > 50 Gy, median dose of 64 Gy) and low-dose (50 Gy) groups according to their prescription doses (n = 35, 43, respectively). Chemotherapy regimen consisted of cisplatin (75 mg/m2, d1) and 5-FU (500 ~ 600 mg/m2, D2 ~ 5) starting at days 1, 28, 49 and 70 after the beginning of radiotherapy with 2 ~ 4 cycles. The two groups were compared in terms of the early treatment outcomes, the side effects and survival rates. Results The 1,3 and 5-year survival rates for the high and low dose groups were 71.4%, 34.3%, 25.7%and 76.7%, 41.9%, 30.2%, respectively. The median survival time was 19 and 22 months respectively without statistical difference. The high dose group was more likely to have higher incidence rate of grade Ⅲ to Ⅳ myelosuppression in spite of the statistical difference. The high dose group had significantly higher incidence of esophagitis than did the low dose group (P=0.040). Conclusion For esophageal carcinoma with only indications of concurrent chemoradiotherapy, te low dose radiation (50 Gy) has comparable outcomes and less side effects compared with the high dose radiation (>50 Gy).

BACKGROUND:Umbilical cord blood stem cel s can be differentiated into functional liver cel s in vivo, instead of mature liver cel s in the treatment of liver diseases. OBJECTIVE:To observe the effect of umbilical cord blood stem cel transplantation on decompensated cirrhosis in rats. METHODS:Twenty Sprague-Dawley rats were enrol ed and given 40%carbon tetrachloride peanut oil to make decompensated cirrhosis models. Eight weeks after modeling, model rats were randomized into control and experimental groups (n=10 per group), and subjected to injection of umbilical cord blood stem cel suspension (2 mL, 1.0×107/L) or cel culture medium (2 mL) via the tail vein, respectively. At 4 weeks after injection, levels of serum aspartate aminotransferase, alanine aminotransferase, albumin, total bilirubin, hyaluronic acid, laminin, procol agen III and type IV col agen were detected;rat liver tissues were sliced for pathological observation. RESULTS AND CONCLUSION:Compared with the control group, the albumin level was significantly increased but the levels of serum aspartate aminotransferase, alanine aminotransferase, total bilirubin, hyaluronic acid, laminin, procol agen III and type IV col agen decreased significantly in the experimental group (P<0.05). From the pathological view, severity of liver cirrhosis was lower in the experimental group than the control group. Therefore, umbilical cord blood stem cel transplantation can effectively restore the liver function of decompensated cirrhosis in rats.

Objective With the emerging omnipresence of arthroscopy, the plica syndrome has achieved a clinical recogni-tion as a pathological entity .This study is to investigate the clinical diagnosis and treatment of the medial plica syndrome of the knee . Methods We retrospectively analyzed 198 cases of medial plica syndrome, internal semilunar cartilage and chondromalacia patellae in the knee joints treated in our department from January 2008 to December 2011 .All the patients received physical and MRI examina-tions before admission and underwent plicaectomy, their knee function evaluated according to their Lysholm scores pre-and post-opera-tively. Results The diseased plica synovialis was completely excised in 46 cases diagnosed as simple medial plica syndrome by ar-throscopy.Forty-four of the patients were followed up for 6 to 32 (mean 26) months, and the excellence rate of treatment result was 95.5%. Conclusion Medial plica syndrome of the knee constitutes a larger proportion of knee disorders, for which arthroscopy re-mains the best diagnostic option and total excision of the diseased plica synovialis is an effective treatment .

OBJECTIVE To investigate the effect of furanodiene(FDE),a diterpene derived from the medicinal plant Zedoary,on apoptosis of human gastric cancer MGC-803 cells induced in vitro. METHODS MGC-803 cells were treated with FDE 46.29~740.74μmol·L-1 for 24,48 and 72 h,and the cell viability was detected with MTT assay. Cell morphology was observed by light microscopy and Hoechst33342 staining. Flow cytometry was used to detect cell apoptotic rate and cell cycle. Rh123 staining and fluorescence probe DCFH-DA were employed to detect the changes in mitochondrial membrane potential (MMP) and reactive oxygen species(ROS). RESULTS MTT Results showed that FDE 46.29-740.74μmol · L-1 exhibited significantly higher cytotoxicity to gastric cancer MGC-803 cells. IC50 for MGC-803 of 24,48 and 72 h treatment was 347.91,257.41 and 101.01μmol·L-1,respectively. Treatment with FDE 92.58-370.32μmol·L-1 for 24 h also caused significant morphological changes in MGC-803 cells. AnnexinⅤ-FITC/PI double staining showed that the apoptotic rate increased after FDE 92.58-370.32μmol·L-1 treatment for 24 h(P<0.05). FDE enabled MGC-803 cell cycle arrest in S phase. DCFH-DA staining showed that FDE resulted in an increase in intracellular ROS levels(P<0.05) when PDE concentration was 370.37μmol·L-1(P<0.05). MMP decreased after FDE treatment when PDE concen?tration was 370.37μmol·L-1(P<0.05). CONCLUSION FDE Possesses potent tumor selected toxicity and can induce apoptosis of MGC-803 cells through cell cycle arresting,which is related to inhibition of DNA biosynthesis.

OBJECTIVE To study the effect of frequency difference and intensity difference on mismatch negativity (MMN) change in normal persons. Emphatically to observe the effect on the latency and amplitude of normal people's MMN, as well as the threshold of the acoustic difference which may induce the MMN. METHODS Twenty-four adults were included in this study. Their thresholds of pure tone audiometry were within 20dBHL. The MMN were measured by using the Smart EP ( ear potentiometer provided by the company of Intelligent Hearing) and the rule of the change by the difference of frequency and intensity to the latency and amplitude of normal people’s MMN were studied. RESULTS Along with the decreasing of the difference of the frequency, the MMN latency prolonged gradually. The amplitude of the MMN decreased gradually as the decreasing of the intensity difference. CONCLUSION A stable MMN graph is an important indicator of objective physiological test with hearing distinguish.
