Objective To study the ultrasonic features of the congenital vaginal reclined septum syndrome (CVRS) in order to apply a precise way for operations. Methods To diagnose CVRS accurately before operation, the ultrasonogram and clinical characteristics of 15 cases were studied retrospectively. Results There were duplicated uterus and cervices with ipsilateral renal agenesis on the reclined septum side in all the patients,11 in the right and 4 in the left. All of 10 cases of type Ⅰhad been made final diagnosis before operation according to the specific ultrasonogram and the rest of type Ⅱ and type Ⅲ had been made reliable diagnosis. Conclusions Ultrasonic examination should be the first way to diagnose CVRS.

Aim To investigate the effect of progesterone on the levels of glutamate and ?-aminobutyric acid released from primary cultured rat cerebral cortical neurons.Methods Primary cultured rat cerebral cortical neurons were treated with PROG(10 ?mol?L-1) and the concentrations of amino acid in cell culture media at different time(0.5,1,1.5,2,24,36,48,72 h) were measured by OPA-mercaptoethanol precolumn derivatization technique and HPLC-FLD.Results Compared with control group,PROG treatment significantly reduced the levels of GLU at the time of 1,1.5,2,24,36,48,72 h(P

BACKGROUND:Previous studies have demonstrated that normal rat liver homogenate supernatant can induce human umbilical cord mesenchymal stem cels to differentiate into hepatocyte-like cels with partial hepatocyte functions. However, whether fibrotic liver homogenate supernatant can work or how the inducing effect is remains unclear. OBJECTIVE:To investigate the differentiation potential of human umbilical cord mesenchymal stem cels into hepatocytes under the normal liver and fibrotic liver microenvironment in vitro. METHODS:Liver fibrosis was induced in the SD rats by repeated intraperitoneal injections of 3% thioacetamide at a dose of 200 mg/kg body mass, twice a week for 4 weeks, and then fibrotic liver tissues and normal liver tissues were used to prepare liver homogenate supernatants. Passage 3 human umbilical cord mesenchymal stem cels were used and divided into standard control group (cels were cultured in DMEM/F12 with 10% fetal bovine serum), fibrotic liver homogenate supernatants group (cels were cultured in DMEM/F12 with 10% fetal bovine serum and 50 g/L fibrotic liver homogenate supernatants), normal liver homogenate supernatants group (cels were cultured in DMEM/F12 with 10% fetal bovine serum and 100 g/L normal liver homogenate supernatants). The morphological changes of the cels in each group were recorded under inverted microscope; the protein levels of CK18, AFP, CYP3A4, CYP2E1, CYP2D6 and TPH2 were evaluated using western blot assay. Furthermore, the concentration of albumin in the cels was measured. RESULTS AND CONCLUSION:After a 7-day inducement, the stem cels in liver homogenate supernatants groups lost their fusiform shape and changed into hepatocyte-like cels with the morphous of round shape. Compared with the standard control group, the hepatocyte-like cels in the two liver homogenate supernatants groups exhibited human hepatocyte biomarkers, CK18 and AFP. The standard control group cels could express a little amount of CYP2E1, while cels in the two liver homogenate supernatants groups could express CYP3A4, CYP2E1, CYP2D6, TPH2. Compared with the standard control group, the expression level of CYP2E1 in the two liver homogenate supernatants groups increased significantly (P < 0.01), and however, the relative levels of CYP3A4, CYP2E1, CYP2D6, TPH2 in the two liver homogenate supernatants groups showed no statistical significance (P > 0.05). At the same time, compared with the standard control group, the concentration of albumin in the two liver homogenate supernatants groups markedly increased (P < 0.01), but there was no difference between the two liver homogenate supernatants groups (P > 0.05). Experimental findings demonstrated that both of normal liver tissue and fibrotic liver tissue microenvironments could induce human umbilical cord mesenchymal stem cels to differentiate into hepatocyte-like cels. To achieve the same effect, compared with normal liver tissue, fibrotic liver tissue required lower concentrations, suggesting that fibrotic liver tissue microenvironment may be more conducive to differentiation of umbilical cord mesenchymal stem cels into hepatocytes.

Objective To explore the influencing factor of duration of untreated psychosis(DUP) and the relationship between duration of untreated psychosis and treatment outcome in epidemiological first-episode schizophrenia. Methods 912 medical records of the first episode schizophrenia patients were recruited in the study for epidemiological survey . The general medical data, clinical diagnosis, and treatment outcome were collected. DUP was determined refer to symptom onset for schizophrenia (SOS) scale. Patients were divided into short DUP and long DUP groups according to the median values of DUP values. Results Between short DUP and long DUP groups, the difference in marriage was significant ( P < 0. 05). The unmarried patients in the short DUP group (63.7% ) was higher than the long DUP group (52.6% ), the variance was significant (λ2 =5.990, P<0.05). The divorce in the short DUP group (0.6% ) was lower than the long DUP group (4.4% ) , the variance was significant (λ2 =5.079, P<0.01).The simple schizophrenia in the short DUP group (1.5%) was lower than the long DUP group (4. 1% ) , the variance was significant (λ2 =5.868, P<0.05). The treatment outcomes between the two groups had a significant variance ( λ2 =36.093, P < 0.01) , and the Ridit analysis of treatment outcomes between the two groups showed significant difference ( u = 5.183, P<0.01). The marriage,age of onset and clinical diagnosis were significantly correlated with DUP in multiple factor Logistic regression analysis. Conclusion The marriage,age of onset and clinical diagnosis are significantly correlated with DUP in the first episode schizophrenia patients,the longer of DUP and the worse of treatment outcome.

Objectives To evaluate the association between serum cystatin C and carotid atherosclerosis.Methods Medical data,including physical examinations,serum levels of cystatin C,bilirubin,uric acid and other biochemical markers and duplex ultrasonographic scanning for the carotid artery,of 1741 healthy adults (1193 men and 548 women) who sought physical check-up at Peking Union Medical College Hospital during January 2010 and December 2011 were collected,and those with hypertension,diabetes and liver or renal function failure were excluded.Based on the results of carotid duplex uhrasonography,all the adults checked were assigned to two groups,one with thickened intima-media and atherosclerotic plaque (group A),the other with non-thickened intima-media and non-atherosclerotic plaque (group B).Difference in serum cystatin C,bilirubin,uric acid and other biochemical markers between the two groups was analyzed by using Student's t test.The correlation between the markers and carotid plaque was analyzed by using Spearman correlation analysis.The correlated factors of the carotid thickness and plaque appearance were analyzed by using unconditional Logistic regression analysis.Results Serum level of cystatin C was significantly increased in group A (t =-8.85,P ＜ 0.05).Thickness of carotid intima was positively correlated with serum cystatin C (r =0.21,P ＜ 0.05).In multivariate Logistic regression analysis,high level of serum cystatin C was not an independent risk factor of carotid atherosclerosis.Conclusion Relationship between serum cyatatin C and carotid atherosclerosis was not confirmed in our populations,which should be explored further in cohort studies.
