Objective To study the preventive effects of vitamin K2 on tumor recurrence in patients with hepatocellalar carcinoma (HCC) after radical resection. Methods The clinical data of 50 patients with HCC who received radical resection from March 2006 to March 2007 in No. 181 Hospital of PLA were analyzed retrospec-tively. All the patients were divided into 2 groups according to the random number table. Twenty-six patients in vitamin K2 group were administered with menatetrenone (45 mg per day), and the rest 24 pateints were in the control group. The accumulative and tumor-free survival rates, differences between the 2 groups, multivariate factors for prognosis were analyzed by Kaplan-Meier curve, Log-rank test and Cox regression model, respectively. Results During a period of 36 month follow-up, 10 patients died and 28 had tunor recurrence. The 1-, 2-, 3-year accumulative survival rates were 96%, 92% and 83% in vitamin K2 group, and 96%, 82% and 63% in control group (χ2 = 3.61, P > 0.05). The 1-, 2-, 3-year tumor-free survival rates were 92%, 60% and 38% in vitamin K2 group, and 75%, 42% and 12% in control group, with significant difference between the 2 groups (χ2 =5.61, P <0.05). Univariate and multivariate Cox proportional hazard analysis showed that without taking menate-trenone, the preoperative level of alpha fetoprotein (AFP) ≥800 μg/L and vascular invasion were the indepen-dent risk factors for tumor recurrence. Conclusions Vitamin K2 has a suppressive effect on tumor recurrence of HCC, while patients with AFP≥800 μg/L before operation or with vascular invasion have poor prognosis.

Objective To develop an effective way to evaluate the accurate platelet count in a patient with anticoagulants-induced pseudothrombocytopenia (PTCP).Methods It was studied that various anticoagulants effect on the platelets count for an infrequent patient with anticoagulants-dependent PTCP. When vitamin B6,aminophylline,gentamicin and amikacin were separately added to four anticoagulated blood samples from anticoagulants-dependent patient within 15 min after blood withdrawal,platelets count and morphological changes of blood cells after 4 hours of incubation at room temperature were investigated. The best anti-aggregating agent and its optimal concentration among them were explored.Results The four anticoagulants all could not inhibit the aggregation of the patient's platelets.Only amikaein among the above anti-aggregating agents can prevent and dissociate the aggregation of platelets without apparent morphological changes of blood cells and the platelet counts was stable within 4 hours after blood drawn when amikacin was added either before or after blood sampling.With increasing the concentration of amikaein,the platelet counts increase and then tend to be stable.The optimal concentration of amikacin is 5 mg/ml blood.Conclusions The supplementation of amikaein either before or after blood sampling is a useful method for the diagnosis anticoagulants-dependent PTCP and for the eva/uation of platelet counts in infrequent patients with anticoagulants-dependent PTCP.

In order to demonstrate the taxonomic position of paramyxovirus Tianjin strain and explore its mechanism of pathogenesis. Bioinformatics methods were used to analyze the deduced amino acid sequences of NP, P, M, and L protein of Tianjin strain. Phylogenetic analysis based on NP, P, M, and L protein sequences demonstrated that Tianjin strain belonged to the genus Respirovirus, in the subfamily Paramyxovirinae and most likely a new genotype of Sendai virus. Sequence similarities comparisons indicated that Tianjin strain P protein was poorly conserved, sharing only 78.7%~91.9% amino acid identity with 6 known Sendai viruses, while L protein was the most conserved, having 96.0%~98.0% amino acid identity with other Sendai viruses. Multiple-sequence alignments of Tianjin strain NP, P, M, and L protein with those of 6 known Sendai viruses showed that Tianjin strain possessed a lot of unique amino acid substitutions in protein sequences, 15 in NP, 29 in P, 6 in M, and 29 in L. The presence of these unique amino acid substitutions suggests that Tianjin strain maybe has a significant difference in host or pathological characteristics from the known Sendai viruses.

To culture bone marrow mesenchymal stem cells (BMSCs) of rat in vitro and observe HSV-1 infection on BMSCs, BMSCs were separated from the bone marrow and identified by alizarin red staining and detection of ALP. The morphology of HSV-1 infected BMSCs and the CPE were observed. The total DNA was extracted from HSV-1 infected BMSCs and the desired specific gene fragment of 477bp of HSV-1 was amplified by PCR. Results showed that after BMSCs were induced by mineral-fluid for 14 days, the ALP level was increased and the nodule calcification was formed. The induced BMSCs were manifested to have the characteristics of osteoblasts. CPE couldn't be found in HSV-1 latently infected BMSCs but the 477bp gene fragment was still detectable. HSV-1 could establish latent infection in BMSCs after 7 passages. This study indicated that rat BMSCs could be induced to differentiate into osteoblasts in vitro, therefore they can be used as the seed cells for the tissue engineering. HSV-1 can infect rat BMSCs and develop the latent infection in vitro.

OBJECTIVETo compare the prognosis of small hepatocellular carcinoma patients with hepatitis B virus infection versus hepatitis C virus infection.
METHODS413 patients receiving curative resections at Tianjin Cancer Hospital for small HCC (< or = 3 cm) from January 1997 to December 2003 were divided into four groups: HCV only (n = 75), HBV only (n = 251), HBV and HCV (n = 33), and neither HBV nor HCV (NBNC, n = 54). The preoperative status and postoperative recurrence were recorded. Survival analysis were used to assess the impact of HBV/HCV status on HCC recurrence.
RESULTSPatients with HCV were associated with older age, lower mean preoperative platelet counts and albumin levels, higher mean prothrombin time, alanine aminotransferase and total bilirubin levels. Tumors in patients with HCV are multinodular and less differentiated, and were associated with a higher incidence of vascular invasion and cirrhosis. During the follow-up, the HCV group showed a higher incidence of intrahepatic recurrence and multiple recurrent lesions than the other patients.
CONCLUSIONSHCC patients with HCV infection tended to be older, and were characterized by more severe cirrhosis and higher incidence of tumor multinodular. The statistically significant determinants of reoccurrence in patients with small HCC were HCV infection, presence of vascular invasion and multiple tumors.

A new species of genus shewarella Shewanellade decolorations S12, was isolated from activated sludge of a textile-printing waste-water treatment plant. In the anaerobic condition, S12 could conserve energy for growth by using Fe3 + as the terminal electron acceptor. At the optimal condition of pH8, temperature 30℃, ferric citrate 800mg/L, sodium lactate 2g/ L, yeast extract 0. 5g/ L , the cell growth increased with the raise of the amount of the Fe3+ reduction in 8k The effect of different carbon soucres, nitrogen sources, pH values and growth temperatures on the anaerobic Fe3 + reduction of Shewanella decolorations S12 was investigated. LB was favorable for Fe3 + reduction. Glucose and sodium lactate also were favorable for Fe3+ reduction. The cell growth and Fe3 + reduction increased with the raise of the amount of the yeast extract from 0 to 4g/L The amounts of the sodium lactate of 6g/ L and ferric citrate of 800mg/L were suitable for strain S12 growth and Fe3+ reduction. In the optimum initial pH value range of 6 -8 for Fe3+ reduction, strain S12 growth increased with the raise of the pH val- ue. Strain S12 could growth and reduce Fe3+ at the temperature range of 20 -40℃. The best temperature for strain S12 growth and Fe3 + reduction was 301.
