OBJECTIVETo explore the therapeutic effect of Pushen capsule (PSC) in treating primary hyperlipidemia.

METHODSTwo hundred and forty patients with primary hyperlipidemia were randomly divided into two groups, the 120 patients in the treated group treated with PSC (4 capsules, tid) and the 120 patients in the control group treated with Zhibituo tablet (3 tablets, tid), and they were administered at the same time with Zhibituo placebo. The therapeutic course for both groups was 4 weeks. The therapeutic effect and the effects on blood lipids and viscosity were observed.

RESULTSThe effective rate in the treated group was 76.3%, which was significantly higher than that in the control group (48.7%, P < 0.01). PSC showed a significant lowering effect on TC, TG and LDL-C and raising effect on HDL-C, and the effect in lowering TG was significantly better than that of Zhibituo (P < 0.01). PSC also showed a certain effect in decreasing whole blood viscosity of both high-sheared and low-sheared viscosity.

CONCLUSIONPushen capsule has promising blood lipid regulating effect in patients with hyperlipidemia, and some effects in lowering the blood viscosity.

To investigate the effect of Protein kinase B on the expression and location of p21 in mouse early development. Immunopreciptation technology was used to detect the localization of p21 and Western blotting was used to analyze the expression of p21 after microinjecting mRNA of WT-PKB, myt-PKB and PKB-KD to mouse eggs. There was no obvious difference between the three kinds of mRNA in the expression of p21. But the cell localization altered. The p21 retain in cytoplasm after microjecting myt-PKB. In mouse fertilized egg PKB/Akt controls the cell cycle by changing the cell localization of p21.

OBJECTIVETo investigate the specific cytotoxity of tumor infiltrating lymphocytes (TIL) transfected with chimeric T cell receptor (CTCR) on cells which express KDR.

METHODSA recombinant retroviral plasmid (pMSCVneo-Vhgamma) was constructed by cloning VEGF121-hinger-FcRgamma (Vhgamma) into retroviral vector pMSCVneo. After packaging by PT67, the virus with high titer was used to infect TIL isolated from liver cancer tissues, and then MSCVneo-Vhgamma-TIL was generated. TIL infected with MSCVneo was used as a control. The cytotoxicty of the transgenic TIL on NIH3T3 and HepG2 expressing no KDR and on ECV304 and A375 expressing KDR was detected with MTT colorimetric assay.

RESULTSThe sequences of VEGF121 and hinger-FcRgamma were different from those reported, but the deduced amino sequences were identical to the reported ones. The cytotoxity of TIL infected with MSCVneo on target cell was similar to that of the control TIL; both only had mild cytotoxity on cancer cell line. No significant cytotoxity was found in TIL infected with MSCVneo-cTCR on NIH3T3, but its cytotoxity on ECV304 was significant. The cytotoxity on HepG2 was similar to that of MSCVneo-TIL and uninfected TIL, but cytotoxity on A375 was significantly higher.

CONCLUSIONChimeric T cell receptor permanently grafts TIL cell with predefined new specificity. TIL expressing Vhgamma can selectively recognize and kill vascular endothelial cell and tumor cells which express VEGF receptor KDR.

OBJECTIVETo investigate the relationship between serum alpha-fetoprotein (AFP) variant levels in patients with hepatocellular carcinoma (HCC) and cancer cells disseminating through blood.

METHODSSerum AFP variant levels were measured by crossed immunoaffino-electrophoresis in the presence of lectin before initial surgical treatment in HCC patients. Circulating tumor cells were simultaneously detected in pre-operative blood samples using reverse transcription-polymerase chain reaction (RT-PCR) for AFP mRNA.

RESULTSForty-six HCC patients with serum AFP positive were studied. Serum AFP variant level > or 20% was showed in 37 patients, among whom there were 22 (59.5%) showing AFP mRNA positive. In contrast, the positive AFP mRNA expression was only observed in 2 out of 9 patients (22.2%) with AFP variant level<20% (x(2)=4.02, P<0.05).

CONCLUSIONIn hepatocellular carcinoma patients, increased AFP variant levels are associated with a haematogenous spread of tumor cells.

OBJECTIVETo perform Multiple Linear Regression analysis of X-ray measurement and WOMAC scores of knee osteoarthritis, and to analyze their relationship with clinical and biomechanical concepts.

METHODSFrom March 2011 to July 2011, 140 patients (250 knees) were reviewed, including 132 knees in the left and 118 knees in the right; ranging in age from 40 to 71 years, with an average of 54.68 years. The MB-RULER measurement software was applied to measure femoral angle, tibial angle, femorotibial angle, joint gap angle from antero-posterir and lateral position of X-rays. The WOMAC scores were also collected. Then multiple regression equations was applied for the linear regression analysis of correlation between the X-ray measurement and WOMAC scores.

RESULTSThere was statistical significance in the regression equation of AP X-rays value and WOMAC scores (P<0.05), while there was no statistical significance in the regression equation of lateral X-ray value and WOMAC scores (P>0.05).

CONCLUSION1) X-ray measurement of knee joint can reflect the WOMAC scores to a certain extent. 2) It is necessary to measure the X-ray mechanical axis of knee, which is important for diagnosis and treatment of osteoarthritis. 3) The correlation between tibial angle,joint gap angle on antero-posterior X-ray and WOMAC scores is significant, which can be used to assess the functional recovery of patients before and after treatment.

Objective To investigate the genotype of D class of carbapenemase of carbapenem－resistant Acinetobacter baumannii in traumatology department, so as to guide the rational use of antibiotics as well as prevent the nosocomial infection. Methods A total of 96 strains of Acinetobacter baumannii were collected in traumatology department. Patient history were analyzed and genotype of carbapenemases of OXA－51,OXA－23,ISAba1－oxa－51 and ISAba1－oxa－23 were analyzed by PCR.Results 70.84% (68/96) of Acinetobacter baumannii were isolated from wound tissue. 12 antibacterial agents were tested, 96 strains of Acinetobacter baumannii showed the highest resistance rate (78.13%) to imipenem and the lowest resistance rate (43.75%) to levofloxacin. Among 23 strains of imipenem－sensitive Acinetobacter baumannii, OXA－ 51 gene expression was not detected in 4 strains, however, OXA－23 gene expression were observed in 5 strains. The gene expression rates of OXA－51,OXA－23, ISAba1－oxa－51 and ISAba1－oxa－23 genes were 100%, 95.89%, 79.45% and 71.23% respectively in 73 strains of imipenem－insensitive Acinetobacter baumannii. The rate of gene expression profile of OXA－51+ISAba1－oxa－51+OXA－23+ISAba1－oxa－23 was 65.75% .Conclusion The strains of imipenem－sensitive Acinetobacter baumannii may have the gene expression of OXA－23 of D class of carbapenemase. The main pattern of carbapenemase－producing was OXA－51+ISAba1－oxa－51+OXA－23+ISAba1－oxa－23 in traumatology department,which might be regarded as one of the mechanisms that led to the high resistance of the bacterium of acinetobacter baumannii to carbapenem antibiotics.
