Objective To identify the glycometabolism features ofC57BL/Ksj db/+ mice at gestational period and provide the evidence for the mice used as the animal model of gestational diabetes mellitus (GDM).Methods Ten C57BL/Ksj db/+ female mice and ten wild female mice were randomly selected and mated with wild male mice respectively.Day 3 before mating,days 6,11 and 17 of pregnancy,and day 6 after delivery represented pre pregnancy,early-pregnancy,mid-pregnancy,late-pregnancy and post-pregnancy periods,respectively.The levels of glucose tolerance and fasting insulin of female mice were compared at progestation,different gestational periods and puerperium between the two groups.Days 6,11,14,17 and 20 (before labor) of pregnancy served as five time-points of pregnancy,leptin levels of female mice of the two groups were dynamically monitored during pregnancy,and analyzed at different gestational ages.The data were analyzed by Tukey test of one-way ANOVA.Results (1) Compared with the normal pregnant mice,the levels of glucose tolerance of C57BL/Ksj db/+ female mice were significantly decreased,while the levels of fasting insulin were dramatically increased with the progression of pregnancy [day 6 of pregnancy,(8.6 ± 0.6) mU/L vs (7.5 ±1.1) mU/L; day 11 of pregnancy,(9.8±0.6) mU/L vs (8.5± 1.1) mU/L; day 17 of pregnancy,(10.4±0.8) mU/L vs (9.9±0.5) mU/L; t=1.859,4.056 and 3.078,P=0.085,0.000 and 0.000] and recovered to the pre-pregnancy level after delivery.(2) The level of leptin in serum of C57BL/Ksj db/+ pregnant mice was significantly higher than that at non-pregnant period [pre-pregnancy and days 6,11,14,17 and 20 of pregnancy:(911.0±238.8) ng/L,(1 342.2± 132.3) ng/L,(1 821.9±238.2) ng/L,(1 816.3± 142.3) ng/L,(1 752.4± 126.6) ng/L,and (1 926.4±61.6) ng/L,respectively; t=3.887,8.210,8.161,7.585 and 9.153,P=0.005,0.000,0.000,0.000 and 0.000],but showed no apparent change with the gestational ages after mid-gestation.Conclusion Changes of glycometabolism and the levels of leptin and insulin of C57BL/Ksj db/+ pregnant mice during pregnancy are similar to those of GDM patients,the levels of fasting insulin are dramatically increased with the progression of pregnancy,and return to normal after delivery,the level of leptin is higher than that at non-pregnant period,but is not correlated with the gestational ages.C57BL/Ksj db/+ pregnant mice can be used as the animal model of GDM.

Objective To investigate the auditory sensory gating P50 in schizophrenia patients with homicide during three months of follow up. Methods Twenty-five patients with schizophrenia patients with homicide and 27 healthy adults matched with age and education level were recruited in the present study. P50 was recorded in twenty-seven normal controls and twenty-five schizophrenia patients at the baseline. P50 was repeatedly recorded in eleven patients who completed the follow-up at three months following antipsychotics treatment. The psychotic symptoms of patients were assessed with Positive and Negative Syndrome Scale (PANSS) at the same time. Results ①In comparison with normal controls, schizophrenia patients with homicide showed increased S2-P50 amplitude (P<0.01), increased S2/S1 ratio (P<0.01), decreased S1-S2(P<0.05), and 100(1-S2/S1) (P<0.01) at the baseline and after three months treatment. The differences in P50 amplitude, latency, and P50 suppression index between the baseline and after three-month treatment in schizophrenia patients with homicide were not significant (P>0.05). ② Schizophrenia patients with homicide after three-month treatment showed decreased PANSS total scale, positive scale, general psychopathology scale, and six symptoms scales such as lack of response, thought disorder, activation, paranoid, depression, and aggression (P<0.05). ③ No significant correlations were found between the S2/S1 ratio, S2-S1, and 100(1-S2/S1) with disease duration, PANSS scores, and six symptoms scales at either baseline or after three-month treatment (P>0.05). Conclusions Schizophrenia with homicide has sensory gating deficits and P50 suppression index might be a stable trait maker for schizophrenia with homicide.

Objective To investigate the dynamic changes of serum autoimmune antibodies before and during treatment in auto-immune liver disease(AILD)and to study their clinical application and the practical significance.Methods The indirect immunoin-fluorescence was used to measure serum anti-nuclear antibody(ANA)on admission and at different clinical treatment time (1,3,12, 24 months)in 64 cases of autoimmune hepatitis(AIH)and 57 cases of primary biliary cirrhosis(PBC).At the same time the immu-noblot analysis was adopted to detect the liver disease related antibodies (anti-AMA-M2 antibody,anti-Sp100 antibody,anti-gp210 antibody,anti-LKM-1 antibody,anti-LC-1 antibody and anti-SLA antibody).The correlation analysis was performed by combining with the detection results of the liver enzymology.Results The detection rate of serum ANA before treatment was 57.8% in the AIH patients and 61.4% in the PBC patients respectively,and the titer was mostly distributed in 1∶320 and 1∶640.During treat-ment,the positive rate and titer of serum ANA in the AILD patients had no obvious change with the disease condition relief(P>0.05);in the liver disease antibodies detection,only anti-AMA-M2 antibody,anti-Sp100 antibody and anti-gp210 antibody were de-tected in the PBC patients,and the detection rates were in turn 73.7%,17.5% and 26.3% respectively;6 items of antibody were detected to different extent in the AIH patients,but which was dominated by the specific detection of anti-LKM-1 antibody,anti-LC-1 antibody and anti-SLA antibody;the liver function indexes in the ALID patients were gradually recovered after 1,3,12,24 months treatment(P<0.05),there was no significant change in the autoimmune antibodies detection(P>0.05).Conclusion The autoimmune antibodies detection plays a very important role in diagnosis and differential diagnosis of AILD,but which has no change with the disease condition relief,thus can not be used as the index of the clinical curative effect observation.

Objective The CYP19 gene product enzyme aromatase mediates the conversion of the androgen testosterone to es -tradiol.The aim of this study is to investigate whether the CYP19A1 gene single nucleotide polymorphism (SNP) is associated with the susceptibility to polycystic ovary syndrome (PCOS) and serum hormone levels. Methods We conducted a case-controlled study, which included 373 PCOS patients and 313 healthy controls.We genotyped SNP rs2899470 in the subjects using the polymerase chain re-action-restriction fragment length polymorphism ( PCR-RFLP) method and analyzed the frequencies of genotypes and alleles as well as the association of different genotypes with age , menarchal age, body mass index (BMI), and serum levels of hormones. Results The gen-otypic distributions of rs2899470 GG, TG, and TT in the PCOS women were 44.5%, 49.6%, and 5.9%, respectively, significantly dif-ferent from 39.3%, 48.6%, and 12.1%in the healthy controls (P=0.013).The frequency of the G allele was 69.3%in the former, remarkably higher than 63.6%in the latter (P=0.025).The rs2899470 genotypic frequencies were associated with the serum E 2/T lev-els in the PCOS patients. Conclusion SNP rs2899470 in the CYP19A1 gene is associated with the susceptibility to PCOS , and so is the genotype of rs2899470 with serum E2/T levels, which may be attributed mainly to the reduced activity of aromatase .

OBJECTIVETo study the effect of Flos Daturae alkaloids (FDA) on TGF-beta1-1uuuu;U epithelial-mesenchymal transition (EMT) of human pulmonary adenocarcinoma A549 cells.

METHODSA549 cells in vitro cultured were randomly divided into 5 groups, i.e., the blank control group, the TGF-beta1 group, the low dose FDA group, the medium dose FDA group, and the high dose FDA group. The morphologies of A549 cells were observed. Expressions of cytokeratin (CK)-19 and alpha-smooth muscle actin (alpha-SMA) were detected by Western blot and real-time PCR at 24, 48, and 72 h, respectively.

RESULTSA549 cells in the TGF-beta1, group turned from cobblestone to spindle shape gradually. Those in low, medium and high dose FDA groups showed similar shapes to those of the TGF-beta1 group. There was no statistical difference in the morphology of A549 cells among the 3 dose FDA groups (P > 0.05). Western blot showed that, when compared with the blank control group, the expression of CK-19 was down-regulated, but the expression of alpha-SMA was up-regulated in the TGF-beta1 group (P < 0.01). Compared with the TGF-beta1, group, the expression of CK-19 was up-regulated, but the expression of alpha-SMA was suppressed in low, medium and high dose FDA groups (P < 0.01). The CK-19 expression obviously increased, but the alpha-SMA expression was suppressed in high dose FDA group at 72 h (P < 0.01). Real-time PCR results showed, as compared with the TGF-beta1 group, the mRNA expression of CK-19 was increased, but the mRNA expression of alpha-SMA was reduced in low, medium and high dose FDA groups (P < 0.01).

CONCLUSIONSFDA had no effect on EMT morphological changes of TGF-beta1 induced A549 cells. FDA could reverse characteristic markers of A549 cells during EMT to some extent, such as expressions of CK-19 and alpha-SMA. The expression of CK-19 (as the epithelium marker) increased and the expression of alpha-SMA (as the mesenchymal marker) was reduced. Besides, they were most obviously seen in the high dose FDA group at 72 h in a dose- and time-dependent manner.
