Stroke is one of the most common diseases among middle and senior - aged people,and depressive disorder,which hinders severely recovery and prognosis,is one of the complications of stroke.This paper analyzes the efficiency of social intervention mode on patients with post - stroke depressive disorder,and comes up with the conclusion that social intervention mode can not only help to ameliorate the occurrence of post - stroke depressive disorder,but also promote the recovery of patients' nervous function.Therefore,the social intervention mode can be regarded as an effective means for medical treatment.

This study was aimed to explore the effect of total flavonoids and saponins from Huang-Qi Ge-Gen (HQGG) decoction on blood glucose (BG), serum lipid, interleukin-12 (IL-12) and interleukin-15 (IL-15) of liver in diabetes mellitus (DM) rats, in order to investigate their interactions in regulating DM processes. A total of 66 SD rats were randomly divided into 6 groups, which were the normal group, model group (A1B1), control group, total flavonoids group (A2B1), total saponins group (A1B2), and total flavonoids and saponins group (A2B2), with 11 rats in each group. Except the normal group, other groups were intraperitoneal injected with streptozotocin (STZ). And the experiment was according to 2×2 factorial design experiment scheme. The BG was determined before STZ injection and 7 days after the STZ injection. After 30 days, BG, serum lipid, IL-12 and IL-15 of liver were tested. Related indexes were calculated to the weighted composite score. Main and interactive effect of total flavonoids and saponins were studied according to the factorial design experiment scheme. The results showed that compared with the normal group, all indexes of model group showed statistical differences (P<0.05). Total flavonoids and saponins from HQGG decoction can effectively reduce BG, without any interactions between them. Both the total flavonoids and total saponins can reduce serum cholesterol (CHO), triglyceride (TG), liver IL-12 and IL-15. And there were interactive effects. The single use of herb achieved better effects than the combination. It was concluded that total flavonoids and saponins from HQGG decoction can reduce BG, CHO, TG, and liver IL-12 and IL-15 levels in rats. However, the regulation of total flavonoids and saponins on indexes mentioned above showed no additive effect.

Cancer, also known as malignant tumor, is the second largest disease after heart disease, which is characterized by genomic instability and mutagenicity. Ataxia telangiectasia and RAD3-related kinase (ATR) are members of phosphatidylinositol 3-kinase (PIKK) family, belonging to serine/threonine kinase, one of the key kinases in DNA damage response (DDR) and DNA repair pathway. This paper reviews the latest progress in the ATR inhibitor field including mechanism of action (MOA), therapeutic applications, and the combination therapy from the perspective of medicinal chemistry. It also discusses the possible challenges and future directions of developing ATR inhibitor antitumor drugs, which could provide the scientists in this field the convenience for access the information and application guidance for clinical studies.

OBJECTIVETo investigate the expression profile of interleuki-1β (IL-1β) in rat myocardium at different time points during hypoxia/reoxygenation(H/R)transition.

METHODSThe isolated Langendorff perfused rat heart model was established.Forty SD rats were randomly divided into sham group (A group) and hypoxia/reoxygenation group (H/R group). The H/R group rats were subdivided into H/R 0.5 h group(B group), H/R 1 h group(C group), H/R 2 h group(D group)according to reoxygenation time. The left ventricular development pressure(LVDP), maximal rates of increase/decrease of the left ventricular pressure(±dp/dtmax) were continuously recorded. The concentration of interleukin-1β(IL-lβ) and creatine kinase-MB (CK-MB) in myocardium was measured by ELISA. The mRNA expression of IL-lβ in myocardium was determined by RT-PCR. Microstructure of myocardium was observed under light microscopy.

RESULTSThe value of LVDP and ±dp/dtmax in hypoxia/reoxygenation group rat were significantly lower than that in sham group(P < 0.05). The expression of IL-lβ and CK-MB at protein level and the expression of IL-1β at mRNA level in hypoxia /reoxygenation group were higher than that in sham group(P < 0. 05). There were significant differences of the above parameters among H/R 0.5 h, 1 h, 2 h group(P <0.05). The concentration of IL-1β and CK-MB, the mRNA expression of IL-1β were higher in H/R 2 h group than that of other groups(P < 0.05).

CONCLUSIONThe high expression of IL-Iβ in myocardium after myocardial hypoxia /reoxygenation in rats might lead to. ischemia/reperfusion injury.

As one of the major sources of infection, viruses could infect all organisms including bacteria, plants, animals, and humans. Infectious diseases caused by viruses pose a great threat and damage to human health and economic activities all over the world. Adaptor-associated protein kinase 1 (AAK1) is a member of the Ark1/Prk1 family of serine/threonine kinases and a specific key kinase regulating the phosphorylation of AP-2 protein μ2 subunit T156. In the past, AAK1 has been regarded as a feasible biological target for the treatment of nerve pain. Recently, scientists have found that inhibiting AAK1 can regulate endocytosis and inhibit virus invasion into cells. Therefore, AAK1 could be the potential target of anti-virus therapy. This paper reviews the research progress of small molecule AAK1 inhibitors in the field of antiviral, analyzes the future research directions and challenges, and provides new ideas for the development of antiviral drugs targeting AAK1.

Objective To explore the effect and indication of splenectomy in liver transplantation.Methods From January 2001 to April 2006,260 patients underwent piggyback orthotopic liver transplantation(PBOLT),and 28 patients had undergone combined PBOLT and splenectomy(splenectomy group).These patients were compared to 56 randomly selected non-splenectomy patients from the same transplant period,meaningly two controls were se- lected for every non-spleneetomy case.Two groups were analyzed with respect to rate of infection and survival rate, as well as biopsy-proven acute allograft rejection within 30 days after transplantation.Results Rate of infection in the splenectomy group was higher than that in the non-splenectomy patients(85.7% vs 55.4%,P

BACKGROUNDDelayed graft function (DGF) is common in kidney transplants from organ donation after cardiac death (DCD) donors. It is associated with various factors. Determination of center-specific risk factors may help to reduce the incidence of DGF and improve the transplantation results. The aim of this study is to define risk factors of DGF after renal transplantation.

METHODSFrom March 2010 to June 2012, 56 cases of recipients who received DCD kidneys were selected. The subjects were divided into two groups: immediate graft function (IGF) and DGF groups. Transplantation factors of donors and recipients as well as early post-transplant results of recipients were compared between the two groups.

RESULTSOn univariate analysis, preoperative dialysis time of recipients (P < 0.001), type of dialysis (P = 0.039), human leucocyte antigen (HLA) mismatch sites (P < 0.001), the cause of brain death (P = 0.027), body mass index (BMI) of donors (P < 0.001), preoperative infection (P = 0.002), preoperative serum creatinine of donors (P < 0.001), norepinephrine used in donors (P < 0.001), cardiopulmonary resuscitation (CPR) of donors (P < 0.001), warm ischemia time (WIT) (P < 0.001) and cold ischemia time (CIT) (P < 0.001) showed significant differences. Recipients who experienced DGF had a longer hospital stay, and higher level of postoperative serum creatinine.

CONCLUSIONMultiple risk factors are associated with DGF, which had deleterious effects on the early post-transplant period.

OBJECTIVETo understand the epidemics and antigenic drift of influenza viruses in China from 2000 to 2001.

METHODSThe viruses were grown in embryonated hen eggs with 9 - 10 days old. The egg allantoic fluids with influenza viruses were used. Virion RNA was transcribed into cDNA by reverse transcriptase while cDNA amplified by PCR. Products of PCR were purified. RNA sequence analysis was then performed. Finally, phylogenetic analysis of the sequencing data was performed with MegAlign (Version 1.03) and Editseq (Version 3.69) software.

RESULTSData from comparison of amino acid sequence on HA1 domain of HA protein molecule between H1N1 viruses isolated in 2001 and A/Shanghai/7/99 (H1N1) strain indicated that there was only one difference of amino acid located at 190 position (antigenic determinant D). However, phylogenetic analysis showed that there were two distinguishable genetically lineages of H1N1 viruses co-circulating in men in China in 2001. Two antigenically distinct genetic lineages of influenza B viruses were still existing in men in China. Most of influenza B viruses were Yamagata-like strain and there were two different amino acid sequences located at 197 and 199 position on HA1 domain of HA protein molecule, between Victoria-like virus isolated and B/Shandong/7/97 strain. When comparing amino acid sequences on HA1 protein domain of H3N2 viruses isolated in 2000 with those of A/Sydeney/5/97 (H3N2) virus, it was revealed that there were 7 - 8 differences of amino acid sequences between them. However, there were four differences related to amino acid sequences on HA1 protein domain between H3N2 viruses isolated in 2000 and in 2001. These results were further demonstrated by analysis of phylogenic tree.

CONCLUSIONSInfluenza was not prevalent in China from 2000 to 2001. The antigenic drifts of H3N2 and B/Victoria-like viruses occurred. Two antigenically distinct genetic lineages of influenza B viruses were still co-circulating in men in China. Two genetically distinct lineages of influenza A (H1N1) virus were also co-circulating in men in China.

OBJECTIVETo study the DNA methylation status of WT1 gene promoter region in hematologic malignancy cell lines and its correlation with WT1 gene expression.

METHODS1. RT-PCR and methylation-specific PCR were performed for detecting WT1 gene expression and DNA methylation status in its promoter region in 8226, HL-60, Jurkat, K562, KG-1, NB4, Raji, SHI-1, U266 and U937 cell lines. 2. Treatment of U937 cells with 5-aza-CdR, a demethylation inducing agent and the changes in WT1 gene expression level and its promoter region methylation status were determined.

RESULTS1. HL-60, K562, KG-1, NB4 and SHI-1 cells showed higher levels while 8226, Jurkat, Raji, U266 and U937 cells showed extremely low levels of WT1 expression. DNA hypermethylation in WT1 gene promoter region was identified in 8226, Jurkat, Raji, U266 and U937 cells. 2. The WT1 gene expression in U937 was enhanced after treatment with 5-aza-CdR accompanied with the decrease of methylated and the increase of unmethylated levels in its promoter region.

CONCLUSIONModulation of the DNA methylation status in WT1 promoter region is one of the epigenetic mechanisms for regulating its expression.

OBJECTIVETo investigate retinoblastoma (Rb) associated protein 46 (RbAp46) gene expression levels in bone marrow (BM) cells of leukemia patients.

METHODSReal-time quantitative reverse polymerase chain reaction (QRT-PCR) method was used for detecting RbAp46 expression levels in BM cells of 140 patients with acute leukemia (AL), 13 with chronic myelogenous leukemia in chronic phase (CML-CP), 7 with CML in blast crisis (CML-BC) and 32 with non-leukemic disorders.

RESULTSThe M-Estimators of RbAp46 were higher in 98 newly diagnosed ALs and 5 relapsed ALs than in 28 ALs in complete remission (CR) and 32 non-leukemic controls (178.23 and 213.65 vs 85.89 and 88.08, respectively). No statistic difference was found between the CR group and control group, or between the newly diagnosed group and relapsed group. The M-Estimators of RbAp46 in patients with CML-CP was 58.27, similar to that in control, but much lower than that in CML-BC (173.24). Among 98 newly diagnosed ALs, the M-Estimators of RbAp46 in M(3) and M(4) were the lowest in all of the subtypes. Furthermore, the RbAp46 expression levels were not correlated with the expression of the fusion genes of bcr/abl, PML-RARalpha, and multidrug resistant gene (mdr1), but were positively correlated with Wilms' tumor gene (WT1) expression levels and negatively with AML1/ETO fusion gene expression.

CONCLUSIONRbAp46 expression levels in ALs and CML-BC were strikingly higher than that in non-leukemias and CML-CP, and might participate in leukemogenesis.
