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 study the expressions of metadherin (MTDH) and cyclinD1 in esophageal squamous cell carcinoma (ESCC) and their clinical significances. Methods The protein expressions of MTDH and cyclinD1 were detected by immunohistochemistry in 78 cases of ESCC. Results The positive expression rate of MTDH in ESCC was 71.79%(56/78) and the positive expression rate of cyclinD1 in ESCC was 74.36%(58/78). The expressions of MTDH and cyclinD1 were significantly correlated with the degree of differentiation and lymph node metastasis (both P< 0.05), but not with the age, gender of patients and depth of tumor invasion (all P> 0.05). Conclusion The over expressions of MTDH and cyclinD1 protein may involve in the occurrence and development of esophageal carcinoma, which play important roles in the invasion and metastasis of esophageal cancer.

OBJECTIVE:To observe the efficacy and safety of carboprost and Foley catheter for the expand cervix before hys-teroscopic electric resection. METHODS:80 patients with hysteroscopic operation were randomly divided into research group and control group. Research group was placed inside the vagina carboprost 1 mg 30 minutes before operation;control group was placed inside the Foley catheter 12 hour before operation. The relaxation degree of the cervix,average operative time,preoperative pain, postoperative morbidity and incidence of adverse reactions in 2 groups were observed. RESULTS:There were no significant differ-ences in the relaxation degree of the cervix,postoperative morbidity and incidence of adverse reactions between 2 groups(P>0.05). The average operative time and preoperative pain in research group were significantly better than control group,the differ-ence was statistically significant(P<0.05). CONCLUSIONS:Carboprost and Foley catheter have good efficacy and safety for ex-pand cervix before hysteroscopic electric resection,however,carboprost is better than Foley catheter in terms of average operative time and preoperative pain.

Objective To explore the cytotoxicity of the cytotoxic T lymphocyte (CTL) induced by SW480 sonicate sensitized dendritic cells (DC) on the colon cancer cell line SW480. Methods PBMC were separated from the HLA-A*0201 donor and DC were cultured with rhGM-CSF, rhIL-4 and rhTNF-α. The same donor's primary CTL were stimulated by DC loaded with SW480 sonicate. The cytotoxicity of CTL on SW480 (HLA-A*0201 positive) and K562 (HLA-A*0201 negative) was determined by the MTT method. Results The cytotoxicity of the CTL on SW480 was stronger than that on K562 (P ＜0.05). Conclusion The DC vaccine can stimulate specific CTL which can trigger cytotoxic activity on the target cells and this cytotoxicity is related to MHC restriction.

ObjectiveTo identify the pathogen of an aseptic meningitis outbreak which occurred in Linyi City of Shandong Province during the summer of 2009,and to analyze the genetic variations of Coxsackicvirus B5 (CVB5) isolates.MethodsForty-two cerebrospinal fluids (CSF) specimens were collected from aseptic meningitis cases and virus isolation was performed. The viral RNA was extracted and amplified from the positive specimens using reverse transcription polymerase chain reaction (RT-PCR).The partial VP1 coding region was purified and sequenced. The phylogenetic trees based on VP1 sequences were constructed among CVB5 isolates and those in GenBank.ResultsSeventeen enteroviruse strains were isolated from 42 CSF samples with 40.5％ isolation positive rate. All these strains were identified as CVB5 using both microneutralization test and molecular typing methods. Homology comparisons indicated that the nucleotide acid identities and amino acid sequence identities were 92.3 ％- 100.0％ and 98.7 ％- 100.0％,respectively among these CVB5 isolate.s,and compared with the Faulkner prototype strain,which were 81.0％-82.4％ and 96.6％97.0％,respectively.Phylogenetic analysis on VP1 sequences showed that all CVB5 could be separated into four genogroups of A,B,C and D.Isolates of this outbreak belonged to genogroup D.Interestingly,two distinct genogroups in the phylogenetic tree were observed among the 17 isolates.Conclusions CVB5 is responsible for the outbreak of aseptic meningitis in Linyi City of Shandong Province,China. The genetic diversity is high among the isolates and all belong to genogroup D.

Objective To investigate the effect of JUC on the incisions for episiotomy.Methods Three hundred primiparas to undergo episiotomy in our hospital were divided into two groups in equal number.The experiment group was given JUC Spray before suturing and the control group did not use any solution.In the two groups,antibiotics were not used after the operation,and the incisions were only cleaned with 0.5%povidone-iodine 2 times a day.Result There were significant differences between the two groups in terms of postoperative pains,inflammation and healing in the wounds,and hospital stay(P<0.05).Conclusions Application of JUC after episiotomy could be long-acting in antibacteria.It can reduce wound pain,improve wound healing rate, decrease the medical cost and shorten the hospital stay.

BACKGROUND:Abnormal immunological function is possibly observed after cardiac valve replacement. However, effect of continuous venovenous hemofiltration on immunological function after cardiac valve replacement is rarely reported.
OBJECTIVE:To observe the effect of continuous venovenous hemofiltration on the cellular immune function in patients with multiple organ dysfunction syndrome after cardiac valve replacement.
METHODS:Thirty-one patients with multiple organ dysfunction syndrome after cardiac valve replacement in Xijing Hospital, the Fourth Military Medical University of Chinese PLA, from August 2008 to July 2009, were included in this study. They were treated with continuous venovenous hemofiltration using AV600 hemofilter and were divided into two groups:survival group (17 survivors) and death group (14 deaths). In addition, 16 healthy blood donors served as the control group.
RESULTS AND CONCLUSION:The duration of acute renal failure before continuous venovenous hemofiltration of survival group was significantly lower than that of death group (P<0.05). Before continuous venovenous hemofiltration, the CD4+/CD8+ratio and Th1/Th2 ratio of survival group and death group were lower than that of control group (P<0.05), and lymphocyte apoptosis rate and Fas/FasL antigen expression were higher than that of control group (P<0.05). This evidence suggested the presence of immunosuppression state and Th1/Th2 disbalance. During continuous venovenous hemofiltration, the CD4+/CD8+ratio and Th1/Th2 ratio of survival group were gradual y increased (P<0.05), while lymphocyte apoptosis rate and Fas/FasL antigen expression were gradual y decreased (P<0.05) at 24 hours. The above changes were observed in both survival group and death group, but emerged latter in death group. Continuous venovenous hemofiltration can improve cellular immune function, maintain the balance of T lymphocyte subsets and Th1/Th2, down-regulate Fas/FasL expression on the surface of lymphocyte membrane, and decrease lymphocyte apoptosis rate in patients with multiple organ dysfunction syndrome after cardiac valve replacement. Early continuous venovenous hemofiltration can improve patients’ prognosis.
