Objective:To study the positive expression rate of M2 subtype of macrophage cell surface molecules and the inflammatory factors of PPS in IL-4-induced M2 macrophage.Methods:The experiment was divided into 5 groups:blank control group, Model group,PPS groups(50 μg/ml,100 μg/ml and 200 μg/ml).The expression of CD206 and CD23 was used as bio-maker to confirm IL-4 induced macrophages by treating RAW264.7 with 20ng/ml of IL-4.IL-4 induced RAW264.7 cells were treated with PPS of 50μg/ml,100μg/ml and 200μg/ml for 24 h.Then the expression of CD206,CD16/32 and CD40 were analyzed by flow cytometry, and the mRNA expression of IL-1β,TNF-α,IL-10 and iNOS were detect by qRT-PCR.Results: After treated with IL-4,the positive rate of CD206 of RAW264.7 were high.After treated with PPS ,the rate of CD16/32 and CD40 in IL-4 induced RAW264.7 cells were high ,the expression of CD206 decreased,and the mRNA level of IL-1βand TNF-αincreased.Conclusion:RAW264.7 cells can be polarlized to M2 subtype macrophage by using 20 ng/ml IL-4.PPS enhances the mRNA of IL-1β,TNF-αand the expression of CD40, CD16/32 in IL-4-induced RAW264.7 cells .These results indicate that PPS can induce the M2 subtype to become M1 macrophages, can improve immune function of macrophages.

Objective To study the differences in retinoic acid receptor γ(RARγ) mRNA expression levels in blood leukocytes between antipsychotic-free and antipsychotic-naive schizophrenic patients and healthy control,especially in different genders. Methods Forty-three acute schizophrenic patients who were antipsychotic-naive or antipsychotic-free for at least three months (male = 34, female = 9) and 39 age- and sex-matched healthy subjects (male =25 ,female = 14) were included for blood leukocytes expression of RAR γ mRNA ,using real-time PCR technique. Results Kolmogorov-Smirnov Z analysis showed a significant increase of RARγ mRNA (P =0.041) level in blood leukocytes of pooled schizophrenic patients(0. 027 ± 0. 003) than in the healthy subjects (0. 020 ± 0.002). The elevation was mainly found in the female patients (0. 030 ± 0.003). Within-sex analysis showed that the female schizophrenic patients showed a trend increase (P = 0. 166) of RAR γmRNA expression compared with the male patients (0. 026 ± 0. 001) and exhibited greater RARγ mRNA expression (P = 0. 014)when compared with the female healthy subjects(0. 018 ±0.004). Conclusions The present findings showed an abnormal expression of leukocyte RARγ mRNA level in antipsychotic-free and antipsychotic-naive schizophrenia especially in the female patients. Blood RARγ markers could add to the diagnosis and individualized pharmacotherapy of schizophrenic patients ,especially the female patients.

RESULTBased on available data, indicate suspicious allergies affect Shuxuetong factors may be hospitalized illness, solvent, single dose, concomitant medications.
CONCLUSIONWhen using Shuxuetong for critically ill patients should use caution and pay attention to solvents, dose, combination therapy of choice clinically. Conclusions of this study need further study to be verified.

Objective To determine whether dopamine D5 receptor (D5R) regulates the development of dilated cardiomyopathy (DCM) by inhibiting oxidative stress.Methods We developed heart-specific hD5 mutant (α-MHC-hD5F173L) and wild type (α-MHC-hD5WT) transgenic mice.The NOX2 expression and ROS production were tested in the transgenic mice at three month of age.The α-MHC-hD5F173L mice were treated with either NADPH oxidase inhibitor Apocynin (1mmol/kg/day) or phosphate-buffered saline (PBS) as control by intraperitoneal injection for 4 weeks.After then, the indexes of heart function were measured.The hD5WT and hD5F173L were transfected respectively in rat H9C2 cells, in which ROS production and NOX2 expression were detected at basal level.Results The ROS production and NOX2 expression were higher in the heart of α-MHC-hD5F173L than α-MHC-hD5WT mice.Apocynin treatment improved the heart function of α-MHC-hD5F173L mice.NOX2 expression and ROS production were higher in hD5F173L than hD5WT transfected H9C2 cells.Conclusions Dopomine D5 receptor may prevent DCM development by inhibiting oxidative stress.

OBJECTIVETo characterize molecular and cytogenetic abnormalities in six 46, XX males, and to investigate the clinical manifestations and underlying mechanisms in such patients.
METHODSClinical data of six XX male patients were collected. Karyotyping, multiple polymerase chain reaction (PCR) and fluorescence in situ hybridization (FISH) were utilized to detect and locate the sex determining region (SRY) gene.
RESULTSPCR and FISH showed that all patients were SRY-positive XX males. All patients have their SRY gene located at the tip of derivative X chromosomes, which have resulted from translocation between short arms of X and Y chromosomes. High resolution karyotyping at 550-750 band level has revealed that the translocation breakpoints were at Xp22.33 and Yp11.2 in three patients. In the remaining patients, the breakpoints were either at Xp22.32 and Yp11.31 or Xp22.31 and Yp11.2. The breakpoints at Xp22.32, Xp22.31 and Yp11.31 were rarely reported. Genotype-phenotype correlation analysis indicated that the clinical manifestations were age-specific. Four adult patients have come to clinical attention due to infertility, with typical features including azoospermia and testis dysgenesis, whereas poorly developed secondary sexual characteristics and short stature were main complaints of adolescence patients, and short stature was the sole symptom in a child patient.
CONCLUSIONCombined karyotyping, PCR and FISH are important for the analysis of XX males. Particularly, high resolution karyotyping is valuable for the refinement of chromosome breakpoints and detailed analysis of genotype-phenotype correlation.
