Objective To investigate the effects of DRD1 rs265981,rs4532,rs686 and rs265976 polymorphisms on response to clozapine in resistant schizophrenic patients.Methods DRD1 genotype was determined by SNaPshot SNP technique for 154 patients with resistant schizophrenia.Clinical symptoms were evaluated by Positive and Negative Syndrome Scale (PANSS),and the responder was defined as a reduction of 50％ on PANSS score from baseline after the patients were administered orally clozapine for 8 weeks.Results The frequencies of rs265981 genotypes,alleles and rs265976 genotypes had significant differences between clozapine responder group (88 cases) and nonresponder group(66 cases) in total clinical efficacy ( x2 =10.215,P =0.004 ; x2 =4.082,P =0.041 ; x2 =14.083,P =0.007 ).The frequencies of rs265976 genotypes had significant differences between clozapine response (58 cases) and nonresponse (96 cases) to negative symptom ( x2 =9.805,P =0.046).Conclusion The polymorphisms of DRD1 gene rs265981 and rs265976 may relate with clinical response to clozapine in resistant schizophrenias.rs265981 T/T,allele T and rs265976 genotype A/A are likely to be predictive factors to the improvement of total clozapine therapeutic effects.rs265976 genotype A/A are likely to be predictive factors of negative symptom with treatment of clozapine.

Objective:To investigate the role of sterol regulatory element binding protein-1 (SREBP1) in atorvastatin-induced reduction of nucleotide-binding oligomerization domain-like receptor protein 1 ( NLRP1 ) inflammasome expression. Methods:THP-1 cells were treated with phorbol 12-myristate 13-acetate (160 nmol/L) for 12 h to be differentiated into macrophages. The medium was then replaced with serum-free medium containing lipopolysaccharide and ( or ) atorvastatin. The mRNA expression of NLRP1 and SREBP1 were detected by Real-time PCR. The protein expression of NLRP1 and SREBP1 were determined by Western blot. Furthermore, we observed the effect of SREBP1 siRNA on atorvastatin-induced reduction of NLRP1 expression. Results:Atorvastatin inhibited the mRNA and protein expression of NLRP1 and SREBP1 in the THP-1 macrophages. SREBP1 siRNA showed no significant difference on lowering NLRP1 expression when compared with atorvastatin. Treating cells with SREBP1 siRNA and atorvastatin at the same time resulted in more obvious reduction of NLRP1 expression than single use of SREBP1 siRNA or atorvastatin. Conclusion:Atorvastatin might exert anti-inflammatory effect by repressing NLRP1 expression through the SREBP1 path-way.

OBJECTIVE:To study the improvement effect of lanthanum hydroxide on chronic renal failure (CRF) hyperphos-phatemia in rats. METHODS:CRF hyperphosphatemia rat model were induced and then randomly divided into model group,lan-thanum carbonate group [0.3 g/(kg·d)],calcium carbonate group [4.2 g/(kg·d)] and lanthanum hydroxide high-dose,medium-dose and low-dose groups [1.5,1,0.5 g/(kg·d)] with 10 rats in each group. They were given adenine 0.2 g/(kg·d)intragastrically in the morning,and then given relevant medicine intragastrically in the afternoon;a week later,they stopped taking adenine but con-tinued to take relevant medicine for 22 d. 10 normal rats were selected as normal control group. General examination was conduct-ed,and renal coefficient,serum contents of calcium,phosphorus,PTH,creatinine(Scr)and usea nitrogen(BUN)were detected after last medication as well as renal pathological change. RESULTS:Compared with normal control group,model group showed CRF sign,renal coefficient,the contents of phosphorus,PTH,Scr and BUN were increased,while the content of calcium was de-creased(P<0.01);renal section showed obvious pathological characteristics. Compared with model group,CRF sign of rats were improved in lanthanum carbonate group,calcium carbonate group and lanthanum hydroxide groups. The renal coefficient (except for lanthanum hydroxide high-dose group),serum contents of phosphorus(except for calcium carbonate group),PTH(except for lanthanum hydroxide low-dose group and calcium carbonate group),Scr(except for lanthanum hydroxide low-dose group and calci-um carbonate group)and BUN were all decreased,while serum content of calcium and calcium-phosphorucs product(only in calci-um carbonate group)was increased(P<0.05 or P<0.01). There was no statistical significance in other difference. The renal sec-tion pathological characteristics were improved. CONCLUSIONS:Lanthanum hydroxide can improve renal function and reduce the level of serum phosphorus in CRF hyperphosphatemia model rats.
