Hepatic tumor-specific magnetic resonance (MR) enhancement with Gd-EOB-DTPA can detect and distinguish small hepatocellular carcinoma (HCC) with greater sensitivity than conventional magnetic resonance imaging and computed tomography.Hepatic tumor-specific MR enhancement with Gd-EOB-DTPA is more sensitive in detecting focal HCC,and more reliable in detecting lesions with a diameter smaller than 2cm.Gd-EOB-DTPA is excreted through the kidneys and biliary tract,and thus may provide more information about anatomic structures,demonstrate non-obstruction of the intra- and extrahepatic bile duct system,and provide information about hepatic function.

OBJECTIVETo compare therapeutic effects between surgical and conservative treatment for postoperative lumbar discitis.
METHODSFrom January 2004 to January 2009, 41 patients (17 males and 24 females ranging the age from 37 to 68 years with an average of 53.6 years) with postoperative lumbar discitis were retrospectively studied and divided into two groups. There were 19 patients in operation group, 22 patients in conservative group. Clinical data and features,image data, laboratory examinations, antibiotics utilization, hospital stays and sequelae were recorded and analyzed. Visual analogue scales system (VAS) and Oswestry disability index (ODI) were applied to evaluate therapeutic effects.
RESULTSAll patients were followed up over 2 years. Imaging revealed good bone fusion and no occurrence of discitis. VAS score and ODI at 1 month, 1 year and 2 years were significantly improved after treatment (P < 0.01). While VAS and ODI in operation group at 1 month were improved more than that of conservative group (P < 0.01), and there was no significant difference between two groups at 1 year and 2 years (P > 0.01).
CONCLUSIONSurgical and conservative treatment for postoperative lumbar discitis is effective. Surgical treatment is superior to conservative treatment in a short time, while conservative treatment can achieve long-term satisfactory curative effects.

Objective To identify the differential serum proteins in patients with hepatic injury resulting from coal-burning type of arsenism. Methods Six serum samples were collected from patients with liver injury resulting from coal-burning type of arsenism and healthy subjects(control gruop) in endemic arsenism area. Twodimensional gel electrophoresis(2-DE) was performed to separate serum proteins, after silver staining, the differential expression of proteins were analyzed and then identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry(MALDI-TOF-MS). Results The 2-DE map of serum protein patterns of patients and normal control were established successfully. The results showed that there were an average of (824 ± 31 ) spots and (782 ± 42) spots on 2-DE matching of the patients and control groups and the matching rate was 94.9%(782/824). From these two groups 49 differential protein spots were identified, of which over 3 times the difference in the expression of 30 protein spots were singled out and MALDI-TOF-MS analysis was carried out. Ten proteins were identified. Upregulated expression was observed in alpha-2-macroglobulin, B-cell receptor-associated protein, keratin 1,apolipoprotein A-I, and down-regulated expression was observed in haptoglobin, α2-heremans-schimid-glycoprotein,mitogen-activated protein kinase 4, zinc finger protein 323, ZAP-70 and SP40 in the patient group. Conclusions The well-resolved and reproducible 2-DE serum patterns of patients are established and some differentially expressed proteins are characterized. Whether these proteins of differential expression are serum markers for liver injury resulting from coal-burning type of arsenism need to be further verified.

Objective: To investigate the effect of matrine (Ma) on telomerase activity and cell cycle in hepatoma cell line HepG 2 cells. Methods: TRAP ELISA method was used to determine the telomerase activity in HepG 2 cells which were treated with different concentrations of Ma. Plasmid inserted with 800 bp of the human telomerase reverse transcriptase (hTERT) promoter was transiently transfected into HepG 2 cells by lipofect. Different concentrations of Ma were added into culture media 2 h later, and the activity of the hTERT promoter was tested 48 h after transfection. In addition, the percentages of HepG 2 cells in different cell cycle were determined by the flow cytometry on the 24, 48 and 72 h respectively after adding the different concentrations of Ma. Results: The telomerase activity of HepG 2 was suppressed by Ma at the dose of 750 ?g/ml and the expression of hTERT promoter was also inhibited. The percentage of G 0/G 1 stage cells increased and the percentage of S and G 2/M stages cells decreased in both 500 ?g /ml and 750 ?g /ml groups 48 and 72 h after Ma was added. Conclusion: Ma may have inhibitory effect on hTERT promoter expression, which is related to the telomerase activity and cell cycle regulation.

From original concept and literature of acupoint, the concept and clinical significance of ashi method is discussed, which clarifies that the essence of ashi method is to locate the acupoints by patients' sensitivity on force. The clinical application of heat-sensitive moxibustion has illustrated that positioning method of this therapy is based on the appearance of heat-sensitive moxibustion sensation. Although both types are based on patients' feeling, positioning method of heat-sensitive moxibustion stands on a new angle and uses a new method to locate acupoint. Therefore, it is believed that the positioning method of heat-sensitive moxibustion is the inheritance and development of ashi method.
