Chemokine CXCL9/Mig (monokine induced by IFN-?) belongs to the subfamily of chemotactic cytokines known as CXC-chemokines. In vivo CXCL9 is mainly induced by IFN-? in macrophages and primary glial cells. In vitro, CXCL9 can be secreted by cells such as macrophages, microvascular endothelial cells and neutrophils, in response to the synergy of IFN-? and TLR(toll-like receptor) ligands. CXCL9 is a chemoattractant for activated T lymphocytes, tumor-infiltrating T-lymphocytes, but not for neutrophils or monocytes. The receptor specific for CXCL9 is CXCR3, a G protein-coupled protein which has seven transmembrane domain. The structure and the chemical characterization of CXCL9, as well as its effects on autoimmune deseases, allograft rejection, cancer therapy were reviewed.

BACKGROUND: Delirium is an acute organic brain syndrome caused by various reasons, and it is common in elderly patients. Antipsychotics treatment is an important method to control delirium.OBJECTIVE: To observe the efficacy of new antipsychotic agent of olanzapine and the traditional antipsychotic agent of haloperidol in treating senile delirium.DESIGN: A randomized controlled observation. SETTING: Mental Health Center, the First Affiliated Hospital of Chongqing University of Medical Sciences.PARTICIPANTS: Totally 175 inpatients with senile delirium were selected from the First Affiliated Hospital of Chongqing University of Medical Sciences from September 2001 to September 2003, they were randomly divided into olanzapine treatment group (n=74), haloperidol treatment group (n=72) and a control group(n=29). There were 111 males (63.4%) and 64 females (36.6%). Delirium had occurred for a duration of 30 minutes to 17 days, with an average of (3.02±2.71) days. The enrolled patients were classified according to the etiological factors of delirium: metabolic (n=68), toxic (n=47), structural (n=25) and infectious (n=35).METHODS: Different treatments were used in different groups. Control group (n=29): The patients were only given somatic treatment aiming at delirium, and not any drug for central nervous system was used. Olanzapine group (n=74): Besides the somatic treatment aiming at delirium, the patients were given olanzapine (Zyprexa, produced by Eli Lilly and Company,5 mg/tablet) taken orally or sublingually (fasted patients), the initial dosage was 1.25-2.5 mg per day, and then adjusted to 1.25-20 mg per day. Haloperidol group (n=72): Besides the somatic treatment aiming at delirium, they were treated with intramuscular injection of haloperidol (2.5-10 mg per day). The effects were prospectively observed for 1 week.The scores were observed before enrollment and at 1-7 days respectively,the severity of mental disorder and amelioration were evaluated by the clinical global impression scale-severity of illness (CGI-SI) and global improvement item of clinical global impression scale (CGI-GI). The dosage and time of administration was taken as the dosage and time to take effect when the CGI-SI baseline scores decreased by more than 1 point.MAIN OUTCOME MEASURES: The severity of mental disorder and amelioration were observed.RESULTS: ① The scores of CGI-SI after treatment were significantly decreased in the olanzapine group, haloperidol group and control group, and there were significant differences (P ＜ 0.01). ② The rates of marked effect in the three groups were 82.4%, 87.5% and 31.0%, respectively, and those in the two treatment groups were significantly different from that in the control group (P ＜ 0.01). ③ Both olanzapine and haloperidol began to take effect at small dosages, and it was the fasted in the olanzapine group, followed by the haloperidol group, and slowest in the control group.CONCLUSION: Olanzapine and haloperidol have similar effects in treating senile delirium. However, olanzapine is faster to take effect than haloperidol.

Objective To assess the effect of peroxisome proliferator-activated receptor γ (PPARγ) agonist on prostate epithelial cells in vitro.Methods The expression of peroxisome proliferator-activated receptor γ(PPARγ) was studied by immunocytochemistry and immunofluorescence study.The RWPE-1 human prostate epithelial cell line was treated with PPARγ agonist rosiglitazone 100 μmol/L for 48 h.Analysis of apoptosis was performed by Caspase 3/7 activity assay.Mitochondria depolarization was measured by using the potential-sensitive color,JC-1.The expression of apoptosis-related proteins-Bax was investigated by immunohistochemistry.Results PPARγ mainly located in nucleus and perinucleus.RWPE-1 cell line treated with PPARγ agonist rosiglitazone showed higher Caspase 3/7 activity (10636±1032 RLU) than in control (5936±620 RLU),P＜0.01 and significantly upregulated Bax level (8250±694 vs.6017±563)than in control group,P＜0.01.In addition,mitochondrial membrane potential was depolarized in rosiglitazone treated cells.Conclusions PPARmay play important roles in the pathophysiology of BPH.The mechanism might be that PPARγ regulates cell apoptosis.It is suggested that the mitochondrial and Bax pathway might be involved in signaling PPARγ induced cell apoptosis.

Objective To explore the inhibitory effects of lobaplatin and cisplatin and their regulation of apoptosis-related genes in ovarian cancer cells in nude mice.Methods SKOV3 cells were implanted into nude mice.In monotherapy treatment study,the nude mice bearing human SKOV3 cells were randomly divided into control,lobaplatin,and cisplatin groups,with 7 mice in each group.The mice in each group were received corresponding treatment.The volume of tumor and the weight of nude mice were measured three times per week,respectively.Tumor inhibitory rate was calculated.The protein expressions of bax and bcl-2 were detected by flow cytometry.Results The growth inhibitory rate was 47.2％ in lobaplatin group and 42.8％ in cisplatin group,without significant difference between two groups (P ＞ 0.05).The expression of bcl-2 was decreased but the bax was increased in lobaplatin and ciaplatin groups compared to the control group.Conclusions Lobaplatin can significantly inhibit the growth of ovarian cancer cells,induce apoptosis by down-regulation of bcl-2 and up-regulation of bax.

BACKGROUND:Our previous study has already manifested that Chinese medicine Xiaokening can effectively prevent and treat the early diabetic nephropathy. OBJECTIVE:To compare the effect of rhein and archen on the apoptosis of mesangial cells of rats cultured with high glucose. METHODS:Mesangial cells were stimulated by different concentrations of rhein and archen (20, 40 and 80 μmol/L). Morphology of apoptotic cells was observed by hematoxylin-eosin staining. Karyon apoptosis was examined by fluorescence staining of DAPI. cellapoptosis rate was detected by flow cytometry. RESULTS AND CONCLUSION:The outcome of hematoxylin-eosin staining and DAPI staining indicated that the effect of rhein was much stronger than that of archen on the apoptosis of mesangial cells in the rats cultured with high glucose. Comparison of the apoptosis rate also indicated that the rhein had a stronger effect on the earlier and the later stage apoptotic rate of mesangial cells than archen. Both rhein and archen with different concentrations can induce apoptosis of mesangial cells, but the effect of rhein is much stronger.

Objective To investigate the serum levels of soluble CD23 ( sCD23 ) and thrombopeietin (TPO) in chronic lymphocytic leukemia (CLL) and their correlation with other prognostic factors. Methods The serum levels of sCD23 and TPO of 25 CLL patients were detected with enzyme linked immunosorbent assay. Flow cytometry was employed to determine the expression of CD38 and ZAP-70 protein. Results TPO level in CLL patients was significantly higher than that in normal controls 67.22 - 1881.77 ng/L and 70. 29 - 147. 98 ng/L respectively, P =0. 003. sCD23 level in CLL patients was significantly higher than that in normal controls 129. 80-405. 31 U/ml and 0. 65 -32. 99 U/ml respectively, P =0. 000. TPO level was significantly correlated with Binet stage and CD38 expression. Patients in stage B and C had higher level of TPO than those in stage A 140. 57 -457.48 ng/L and 121.92 - 163.83 ng/L respectively, P =0.014,while TPO level was higher in patients with higher CD38 expression than in patients lower CD38 expression 113.23- 199. 10 ng/L and 141.34 -454. 92 ng/L respectively, P = 0. 033. No significant correlation of sCD23 and TPO levels with ZAP-70 protein, sex, age, peripheral lymphocyte count and lactate dehydrogenase were observed. Conclusion Serum TPO level might be a prognostic factor in CLL.
