Objective To study the effect of treating gouty arthritis with Chinese herbal medicines. Methods 64 patients were randomly recruited into a control group and a treatment group, with 32 cases in each group. The treatment group was treated with taking self-made Qingrelishijiedu formula orally and applying Sanhuang powder externally, while the control group was treated with Xinhuang tablets. Results The cure rate of the healing group was 95.45% in comparison with 86.06%in the control group, showing obvious difference (t=3.25, P＜0.05). The level of blood uric acid of both group reduced after the treatment. The level of blood uric acid of the treatment group was (498.2±79.1) μmol/L before the treatment and (338.6±39.9 ) μmol/L after the treatment, contrasting to (492.3 ± 87.5 ) μ mol/L and ( 396.2 ± 67.3 ) μmol/L in the control group. The difference was also statistically obvious (t=3.09, P＜0.05). Conclusion The effect of treating gouty arthritis by Chinese herbal medicine both orally taken and externally applied was better than western medicine exclusively.

Objective To establish a new allele specific PCR method for GPT typing: and study GPT polymorphism by FLDAS-PCR and PCR-RFLP. Method 248 unrelated individuals of Han were genotyped using FLDAS-PCR and PCR-RFLP. Results Three genotypes were identified with DP of 0.631 in Han population. Typing results by FLDAS-PCR were completely consistent with those by PCR-RFLP. The allele frequencies were GPT * 1 = 0.5423 and GPT * 2 = 0.4577. The population data fitted the Hardy-Weinberg law. Conclusion GPT-FLDAS-PCR and GPT-RFLP method is useful for forensic identification.

Objective To analyze the clinical manifestations,diagnosis,treatment and prognosis of patients with splenic abscess.Method The clinical data,including baseline clinical data,clinical features,past history,pathogen culture result,treatment and the prognosis were retrospectively analyzed in the patients with the discharge diagnosis splenic abscess from January 1991 to March 2012 in Peking Union Medical College Hospital.Results The media time from onset to Peking Union Medical College Hospital of the 19 patients were 29 days.Among them,9 patients were cured,8 were improved and 2 died.Risk factors,such as tumor burden,diabetes,and using immunosuppressive agents etc,can be found in most patients with splenic abscess.All the 19 patients had splenic image changes and non-specific clinical features.The most common three clinical symptoms were fever(18 cases),chills (12 cases) and shivering (11 cases).The most common three signs were abdominal tenderness (9 cases),left upper quadrant sensitive to percussion (7 cases) and splenomegaly (4 cases).The most common etiological culture results were gram negative bacilli (9 cases),gram positive coccus (8 cases),and fungi (4 cases).Conclusions Clinical features are non-specific in splenic abscess patients.Related exam such as ultrasound should be performed on patients with splenic abscess risk factors to avoid misdiagnosis.Empiric antibiotic administration should begin right after the diagnosis based on the image.Pathogen culture should be timely conducted after pus collection.Individual therapeutical protocol should be chosen according to patient's condition.

Objective:To study the cytotoxic effects on tumor cell lines Hela,BGC823,MCF-7,L342,H9101,D6 induced by Fas ligand and anti-human DR5 monoclonal antibodies(Anti-DR5 mAb) and the underlying mechanism.Methods:Fas/DR5 mRNA were detected by RT-PCR. Cytotoxicity exerted by FasL/Anti-DR5 mAb on tumor cell lines was measured by MTT colorimetry and the induced apoptosis was determined by agarose gel electrophoresis.Results:The expression of DR5 on BGC823 and Hela cells were higher and DR5 didn’t express in D6. The expression of Fas on H9101 and L342 were higher and Fas didn’t express in D6. Cell line H9101 and L342 were sensitive to Anti-DR5 mAb and FasL in a dose dependent manner; Cell line MCF-7 and BGC823 were sensitive to FasL but were partially sensitive to Anti-DR5 mAb; Cell line Hela was partially sensitive to FasL but was sensitive to Anti-DR5 mAb; Cell line D6 was insensitive to two apoptosis inductions.Conclusion:Apoptosis induced by Fas ligand and Anti-DR5 mAb vary among tumor cell lines. The underlying mechanism may be relevant to Fas/DR5 mRNA expression,the release of Caspase-8 and Bcl-2.

A highly sensitive electrochemical deoxyribonucleic acid(DNA) biosensor based on multi-walled carbon nanotubes(MWNT)/Ag-TiO_2 composite film was developed. The solution containing Ag-TiO_2-MWNT composite was casted on the carbon paste electrode surface to form a robust film, which combine the advantages of the good biocompatibility of Ag-TiO_2 naocomposite and the fine conductivity, as well as the large active surface area of carbon nanotubes. The composite could greatly improve the immobilization capacity of the probe DNA. The morphologies and electrochemistry of the nanocomposite film were investigated by scanning electron microscopy and electrochemical techniques including electrochemical impedance spectroscopy and cyclic voltammetry, respectively. DNA hybridization events were monitored by a label-free method of electrochemical impedance spectroscopy. This label-free electrochemical impedance DNA biosensor showed high sensitivity and selectivity for phosphinothricin acetyltransferase gene sequence assay. The multicomponents films also displayed a high stability during repeated regeneration and hybridization process.

A series of cycloberberine derivatives were designed, synthesized and evaluated for their anti-cancer activities in vitro. Among these analogs, compounds 6c, 6e and 6g showed strong inhibition on human HepG2 cells. They afforded a potent effect against DOX-resistant MCF-7 breast cells as well. The primary mechanism showed that cell cycle was blocked at G2/M phase of HepG2 cells treated with 6g using flow cytometry assay. It significantly inhibited the activity of DNA Top I at the concentration of 0.1 mg mL-1. Our results provided a basis for the development of this kind of compounds as novel anti-cancer agents.

Objective To investigate the effect of two different odontoblast inducer on the proliferation and apoptosis of rat adiposed-derived stem cells.Methods Adiposed-derived stem cells were collected by enzyme digestion from inguinal fat pads of 4 days post natal mice.Immunocytochemistry was performed to identify the cells.MTT and flow cytometry were tested the prolifera-tion and apotosis of adiposed-derived stem cells by co-cultured with tooth germ cell conditioned medium(TGC-CM)or dentin non-collagenous protein medium (DNCPM).Results Cells displayed a fibroblast-like appearance and positively expressed CD44 and CD105 when cufured to the secend yeneration.After 3 day the cells polarity changed by co-cultured.Count of cells were no obvious change by TGC-CM co-cultured,while that ruduced significantly by DNCPM co-cultured.It confirmed that the proliferation rate of ADSCs in TGC-CM group and control group is higher than DNCPM group(P <0.05),while the apotosis of that in DNCPM group is higher TGC-CM group(P <0.05).Compared with control group,the results had no significant difference(P >0.05).Conclusion TGC-CM may have more advantage as inducer in rat adiposed-derived stem cells differentiate into dentin like cells than DNCPM.
