UNLABELLEDOBJECTIVE; To evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) of qi-yin deficiency phlegm-stasis inter-obstruction syndrome (QYDPSIOS), and to observe its effect on inflammatory factors and fibrinolytic factors.

METHODSBy adopting a randomization grouping, parallel control, and prospective study, 73 T2DM patients of QYDPSIOS were assigned to two groups by random digit table, the Pioglitazone Tablet group (36 cases, as the control) and the JTXZC group (37 cases). All patients maintained their basic therapies and lifestyle as previous after recruitment. Patients in the JTXZC group took JTXZC, 4 pills each time, three times per day, while those in control group took Pioglitazone Tablet, 15 mg each time, once daily. The therapeutic course for all was 8 weeks. The body weight (BW), the height, body mass index (BMI), waist circumference (WC), hip circumference, waist-to-hip ratio (WHR), and scoring of Chinese medicine (TCM) symptoms were observed. Levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h PBG), glycated hemoglobin (HbA1c), tumor necrosis factor alpha (TNF-alpha), nuclear factor kappaB (NF-kappaB), and plasminogen activator inhibitor 1 (PAL-1) were detected. The safety indices such as liver and renal functions and adverse reactions were also observed.

RESULTSCompared with before treatment, BW, BMI, HbA1c, and PBG were obviously lower after 8-week treatment than before treatment in the JTXZC group (P < 0.05). There was no statistical difference in post-treatment BW, BMI, HbA1c, or 2 h PBG between the two groups (P < 0.05). Compared with before treatment, levels of TNF-alpha and PAI-1 were lowered after 8 weeks of treatment in both groups (P < 0.01). The level of NF-kappaB was obviously lowered after 8 weeks of treatment in the control groups (P < 0.05), but it also decreased in the JTXZC group with no statistical difference. The scorings of CM symptoms were somewhat improved after treatment in the two groups (P < 0.01). Besides, better effects were obtained in the JTXZC group (P < 0.05). No severe adverse event occurred in either group during the whole therapeutic course.

CONCLUSIONSJTXZC showed similar therapeutic effect to pioglitazone. Both of them could effectively improve patients' clinical symptoms, the inflammation and fibrinolytic activities in different pathways, with no severe adverse reaction.

Objective To establish CFPAC-1 cell lines deficient in CDC25B2 by recombinant lentivirus, and to investigate the role of this gene. Methods After CFPAC-1 cells were transduced with recombinant lentivirus producing CDC25B2 siRNA, stably transduced cells with green fluorescent protein were selected by flow cytometer. The mRNA and protein expression of CDC25B2 was examined by RT-PCR and Western blot analysis. The effect of the lentivirus on the cell proliferation, cell cycle, clone-forming, migration and invasion ability was analyzed by MTr method, flow cytometer, plate clone-forming assay and Transwell chamber method respectively. Results CDC25B2 siRNA knocked down CDC25B2 expression in CFPAC-1 cells significantly. The silencing efficiency of siRNA transduction by recombinant lentivirns was very high. Proliferation, cloneforming, migration and invasion ability of human pancreatic cancer cell line CFPAC-I were significantly in-creased, while cell cycle was not affected. Conclusion CDC25 B2 plays an important role in cell proliferation, clone-forming, migration and invasion of pancreatic cancer. This research provides experimental evidences for targeting CDC25B2 in gene therapy against pancreatic cancer.

OBJECTIVETo construct mouse enhanced green fluorecence protein (EGFP) -peroxisome proliferator-activated receptor (PPAR)gamma2, and to detect EGFP-PPARgamma2 expression in infected mouse bone marrow mesenchymal stem cells (BMSC).

METHODSCut the fragment of PPARgamma2 from the expression plasmid pcDNA flag PPARgamma2, then cloned the gene fragment into pEGFP-C1 and pEGFP-N1 vector. Subsequently, subclone the fragment EGFP-PPARgamma2 from pEGFP-C1-PPARgamma2 into the shuttle plasmid DC315. HEK293 cells were co-transfected with the constructed recombinant shuttle plasmid DC315-EGFP-PPARgamma2 and large adenovirus helper plasmid pBHGlox deltaE1, 3Cre in mediation of liposome. The obtained replication-defective recombinant adenovirus Ad-EGFP-PPARgamma2 was confirmed. Then it was propagated in HEK293 cells. After the BMSC were transfected for 72 h, adipogenic differentiation was demonstrated.

RESULTSHEK293 cells were transfected with the pEGFP-C1-PPARgamma2 or pEGFP-N1-PPARgamma2 in mediation of liposome. The former green fluorescence protein was better than the latter by fluorescence microscope. The recombinant plasmids were digested and identified. Western blot analysis showed the expression of EGFP-PPARgamma2 in vitro. EGFP-PPARgamma2 protein was detectable in the nucleus of BMSC.

CONCLUSIONThe recombinant adenovirus encoding EGFP-PPARgamma2 fusion protein was successfully constructed, which provided a basis for application of EGFP-PPARgamma2 gene to adenovirus-mediated gene therapy.

OBJECTIVETo explore the expression of manganese superoxide dismutase (MnSOD) in colorectal carcinoma and its relationship with the clinicopathological findings.

METHODSThe expressions of MnSOD in colorectal carcinoma, adenoma, and adjacent corresponding intestinal mucosal tissues were detected by immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR). The relationship between MnSOD expression level in colorectal adenoma and clinical parameters was analyzed.

RESULTSThe expression of MnSOD was negative in adjacent corresponding colorectal tissues. The positive expression rate of MnSOD was 44% (11/25) in colorectal adenoma and 76% (19/25) in colorectal carcinoma (P < 0.05 when compared with the colorectal adenoma and its adjacent tissues). The expression of MnSOD was positively correlated with histopathological grades (P < 0.05) but not with other clinicopathological findings (P > 0.05).

CONCLUSIONThe expression of MnSOD may be associated with the carcinogenesis and progression of colorectal carcinoma, and therefore may be used as a new biomarker.

OBJECTIVETo study the influence of Candida albicans on human immunodeficiency virus (HIV)-positive individuals susceptible to oral candidiasis.

METHODSIn vitro secreted aspartyl proteinase activities, adhesion to healthy buccal epithelial cells of Candida albicans isolates from oral cavities of subjects with and without HIV infection were measured.

RESULTSThe pathogenetic isolates of Candida albicans from HIV-positive patients were significantly lower than that from HIV-negative subjects (P < 0.01) in secreted aspartyl proteinase activities and adhesion to buccal epithelial cells. There was no difference in commensals between these two groups. In the HIV-positive group, no difference was found between the pathogenetics and the commensals. However, in the HIV-negative group, the virulence of the pathogen was significantly higher than the commensals (P < 0.01).

CONCLUSIONSThese results indicate that oral candidiasis was not correlated with some predominant strains of Candida albicans with higher virulence in HIV-positive subjects.

OBJECTIVETo observe the effect of blood activating and cooling, stasis removing herbs on the occurrence rate of Henoch-Schonlein purpura nephritis (HSPN).

METHODSThe 141 HSP children patients with bleeding of the blood stasis syndrome and of the blood heat syndrome (having normal results of urine routines) were assigned to the blood activating and stasis removing group and the blood cooling and arresting group. They were treated with blood activating and stasis removing herbs and blood cooling and arresting herbs respectively for eight weeks. The occurrence rate and time of the renal injury, changes of transforming growth factor (TGF), D-dimer (D-D), immunoglobulin (Ig), urine micro-protein, and urease before and after treatment were observed.

RESULTSThe occurrence of the renal injury in the blood activating and stasis removing group was 36.2%, obviously lower than that in the blood cooling and arresting group (69.4%). The occurrence time of the renal injury was 32.2 +/- 10.6 days, obviously later than that in the blood cooling and arresting group (20.0 +/- 9.0 days), showing statistical difference (P<0.05). The levels of TGF, D-D, IgA, microglobulin (MG), immunoglobulin G (IgG), albuminuria (ALB) of children patients in the blood activating and stasis removing group were lower after treatment than before treatment, showing significant difference (P<0.05). Significant difference was also shown when compared with those of the blood cooling and arresting group (P<0.05).

CONCLUSIONThe application of activating blood and removing stasis method could lower the probability of the renal injury in Henoch-Schonlein purpura (HSP). It played a role in preventing the occurrence of HSPN.
