Objective To analyze the clinical features and its influencing factors of depression pa?tients with and without psychotic symptoms. Methods According to the presence of psychotic symptoms, 374 patients with major depression were divided into psychotic major depression ( PMD group,79 case) and nonpsychotic major depression ( NMD group,268 case) . All patients completed social demographic question?naire ( including gender,age,marital status,educational level,family history,positive family history of psychi?atric disorder,disease onset age,frequency of attack,times of hospitalization,etc.) and Hamilton's depression scale (HAMD?24). Results Positive family history(PMD group 47/79,NMD group 104/268, P<0.01), psychiatric disorder positive family history(PMD group 19/79,NMD group 26/268, P<0.01) and times of hospitalization(PMD group(2.52±1.29),NMD group(1.39±1.31), P<0.01) in the PMD group were signifi?cantly higher than the NMD group.HAMD total scores(PMD total score(47.85±8.69),NMD total score (43.44±8.51), P<0.01),the factor score of anxiety/somatization(PMD group(11.40±3.28),NMD group (9.19±3.54), P<0.01) and cognitive impairment(PMD group(12.24±3.77),NMD group(9.45±3.68), P<0.01) in the PMD group were significantly higher than the NMD group.Disease onset age(PMD group(30.09 ±5.17),NMD group(35.95±9.06), P<0.01),the course of the disease(PMD group(1.58±0.76),NMD group(3.02±2.87), P<0.01),the factor score of day and night change(PMD group(0.76±0.46),NMD group(1.01±0.51), P<0.01) in PMD group were significantly lower than the NMD. Logistic regression anal?ysis showed the major depression with positive family history of mental disorders( β=3.278) ,attack in early age( β=-2.524),seriously cognitive dysfunction in patients( β=3.836) may indicate the psychotic symp? toms( P<0.05).Conclusion PMD patients more positive family history,psychiatric disorder positive family history,likely to be hospitalization,severe symptoms and attack in early age compared with NMD. With posi?tive family history of mental disorders,attack in early age,seriously cognitive dysfunction in patients with ma?jor depression may indicate the psychotic symptoms.

Objective To evaluate the status of abnormal glucose metabolism in patients being alive over 3years after liver transplantation and discuss the possible mechanism of post-transplant diabetes mellitus ( PTDM ).Methods In this study, the clinical data of patients with liver transplantation were collected from April 2001 to December 2008. Patients with diabetes mellitus before operation and those who had died and failed to appear during follow-up were exluded. 199 patients living over 3 years after liver transplantation were follow-up. The prevalence of PTDM was evaluated according to fasting plasma glucose(FPG). Among those without diabetes according to FPG,32patients underwent 75 g oral glucose tolerance test (OGTT) , and fasting and 2 h plasma glucose and insulin were determined. 32 patients were divided into three groups [normal, impaired glucose regulation ( IGR ) , and PTDM groups], proportion of PTDM and homeostasis model assessment ( HOMA ) index were calculated. Results In patients alive over 3 years after liver transplantation, the prevalence of PTDM was 34.67% according to FPG. The OGTT result showed that the proportion of PTDM was 9.38%, IGR, including impaired fasting glucose(IFG) and impaired glucose tolerance ( IGT ) , was 56. 25% , while 34. 37% remained normal. The homeostasis model assessment β cell function index( HOMA-β ) decreased progressively from normal group, IGR group to PTDM group,and that in PTDM group was significantly lower than those in normal and IGR group( P<0.01 ). IGR group had the highest homeostasis model assessment for insulin resistance (HOMA-IR) and PTDM group the next, and HOMA-IR in IGR group was significantly higher than normal group. Conclusion In patients alive over 3 years after liver transplantation, the prevalence of PTDM reached 44.05%. Insulin resistance existed during early period of impaired glucose regulation, while the degeneration of β cell progressed with the worsening of impaired glucose regulation.

Baculovirus has many advantages as vectors for gene transfer. We demonstrated that recombinant baculovirus vectors expressing p35 (Ac-CMV-p35) and eGFP (Ac-CMV-GFP) could be transduced into human kidney 293 cells efficiently. The level of transgene expression was viral dose dependent and high-level expression of the target gene could be achieved under the heterogonous promoter. MTT assay suggested that both Ac-CMV-p35 and Ac-CMV-GFP did not have cytotoxic effect on human embryo kidney 293 cells. Cell growth curve showed the Ac-CMV-p35 and Ac- CMV-GFP transduced and non-transduced cells had similar proliferation rate, so baculovirus-mediated p35expression had no adverse effect on cell proliferation. In addition, baculovirus-mediated p35 gene expression protected human embryo kidney 293 cells against apoptosis induced by various apoptosis inducers such as Actinomycin D, UV or serum-free media. These results suggested that the baculovirus vector mediated p35 gene expression was functional and it could be widely used in molecular research and even gene therapy.

Background Many studies and clinical trials of pharmacologic vitreolysis are already under way to try to improve vitreo-retinal surgery and to liquefy and detach the vitreous from the retina ultimately, including chondroitinase,hyaluronidase,dispase and plasmin. However, there has not been any report on purification of human plasminogen from cord blood plasma and inducing posterior vitreous detachment of the animal eye at present.Objective This study was designed to isolate and purify the production of human plasminogen (Plg) from cord blood plasma with ethanol precipitation and evaluate the efficacy of Plg in inducing posterior vitreous detachment (PVD).Methods Human Plg was Separated and purified from cord blood plasma by ethanol precipitation method. The protein band corresponding to Plg with molecular mass of 92 000 was revealed in SDS-PAGE and confirmed by MALDI-TOF and Mascot database. Anion-exchange chromatography and plasminogen activity assay kit were used to obtain purified Plg with biological activity. Twenty-five fresh pig eyes were enucleated and assigned to 5 groups and 5 eyes for each group. The normal eyes were used as control group. Balanced salt solution(BSS)of 0.1 ml was intravitreally group and standard substance group. All of the eyes were then incubatedfor 60 minutes under the 37 ℃. Retinal histopathology and ultrastructure were examined under the light microscopy, scanning electron microscopy ( SEM ) and transmission electron microscopy (TEM). Results The Plg with potential fibrinolytic activity was successfully extracted and purified from cord blood plasma by ethanol precipitation method. No posterior vitreous detachment (PVD) was seen in normal control group, BSS group and r-SK group following the intravitreal injection under the sem. However,PVD was demonstrated in r-SK+ Plg group and standard substance group under the SEM. The inner limiting membrane ( ILM ) and the retina were well preserved in all of the experimental eyes. No retinal morphology and ultrastructural abnormality were found under the light and SEM and TEM. Conclusion Ethanol precipitation is a feasible way to isolate and purify Plg from human cord blood plasma. Extracted Plg shows potential fibrinolytic intravitreal injection of Plg.

Objective To investigate the effect of total glucosides of paeony ( TGP ) on the expression of Toll-like receptor 9 (TLR9) in peripheral blood B lymphocytes of the patients with systemic lupus erythematosus (SLE). Methods Sixty SLE patients and thirty healthy volunteers were enrolled, peripheral blood mononuclear cells ( PBMC) were isolated from blood samples and divided into 4 groups, which were incubated with CpG-ODN(final concentration was 1 μmol·L-1), CpG-ODN+TGP ( TPG final concentration was 1í10-4 mol·L-1 ) ,TGP and RPMI medium ( as the blank control group) for 48 hours, respectively. FLA ( Flow cytometry analysis) was used to detect the expression of TLR9 on peripheral blood B lymphocytes after incubated. Results ①In the health people, TLR9 expression in the group of CpG-ODN was(9. 10±2. 12) %, which was higher than the blank control group(4. 96±2. 11) % (P<0. 01).②In the SLE patients, the TLR9 expression in the group of CpG-ODN was(14. 86±3. 42)% , which was significantly higher than the blank control group(9. 20±3. 43) %(P<0. 01). The TLR9 expression in the group of CpG-ODN+TGP was (11. 95±3. 63)%, which was lower than that in the group of CpG-ODN (P<0. 05). The TLR9 expression in the group of CpG-ODN with lightly active degree SLE patients was (10. 74±3. 17)%, which was higher than the blank control group(5. 19±2. 05) % (P<0. 01). For SLE from the moderately to vigorously active degree, the expression of TLR9 in the group of CpG-ODN(16. 51±1. 72) % was higher than the blank control group(10. 80±2. 37) %(P<0. 01), but that in the group of CpG-ODN+TGP (13. 59±2. 58) % was lower than the group of CpG-ODN (P<0. 01). Conclusion Our data indicate that TGP antagonize upregulation effect of CpG-ODN on the expression of TLR9 in peripheral blood B lymphocytes.
