OBJECTIVETo investigate the correlation between the pathogeneses of diarrhea-pre- dominant irritable bowel syndrome (D-IBS) complicated functional dyspepsia (FD) patients of Gan-stagnation Pi-deficiency Syndrome (GSPDS) and symptoms, psychological states, and gastrointestinal hormones.

METHODSA total of 111 patients with confirmed D-IBS complicated FD of GSPDS were recruited as the treated group by using Rome III standard and Chinese medical syndrome standard. And 30 healthy volunteers were recruited as the control group. The general condition, scoring for digestive symptoms, and the distribution of GSPDS subtype of all subjects were recorded by a questionnaire, and assessed by Symptom Checklist (SCL-90; a software for psychological test developed by Beijing Huicheng Adult Cor- poration). Meanwhile, plasma levels of 5-hydroxytryptamine (5-HT), somatostatin (SS), vasoactive intestinal peptide (VIP), endothelin (ET), interleukin 10 (IL-10), and interleukin 12 (IL-12) were measured in all subjects.

RESULTS(1) The subtype of D-IBS complicated FD of GSPDS was dominant in Pi-qi deficiency type (51/111,45.9%),Pi yang deficiency type (34/111,30.6%), and GSPDS. There was no statistical difference in the scoring of digestive symptoms among the 3 subtypes (P >0.05). (2) Compared with the control group, the anxiety factor score and the total score significantly increased in all three subtypes of D-IBS complicated FD of GSPDS, and the depression score of Pi yang deficiency type and Gan-depression type also significantly increased (P <0.05, P <0.01); the depression score of Gan-depression type was significantly higher than that of the Pi-qi deficiency type (P <0.01). Plasma 5-HT levels were obviously lower in D-IBS complicated FD patients of GSPDS accompanied with anxiety or depression than in those with no obvious psychological abnormalities, and VIP and IL-10 levels were significantly lower than those in the control group (P <0.05). Plasma VIP levels were also obviously lower in D-IBS complicated FD patients of GSPDS accompanied with anxiety or depression than in those with no obvious psychological abnormalities (P <0.01), and SS levels were significantly lower than those in the control group (P <0.05). There was no statistical difference in plasma ET or IL-12 levels in each patient group, when compared with the control group (P >0.05). (3) Compared with the.control group, plasma 5-HT levels significantly increased, plasma VIP and IL-10 levels significantly decreased in ach subtype of D-IBS complicated FD patients of GSPDS (P <0.05, P <0.01), and no significant change of SS, ET, or IL-12 occurred (P >0.05). Besides, plasma 5-HT levels were significantly higher in Gan-depression type than in Pi yang deficiency type, VIP levels were lower in Gan-depression type than in Pi-qi deficiency type (all P <0.05).

CONCLUSIONSGan stagnation and Pi deficiency were dominant in D-IBS complicated FD patients of GSPDS. Psychological abnormalities, increased plasma 5-HT levels, and decreased plasma VIP levels were closely correlated with Gan stagnation subtype, which provided some reference for looking for objective indicators of Chinese medical syndromes in treating D-IBS complicated FD patients of GSPDS.

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.

AIMTo survey the uptake behavior and subcellular distribution of antisense oligodeoxynucleotide polymethacrylate submicroparticles (AS-ODN-SMP) and infer its mechanism in MGC cell lines.

METHODSMGC cells were incubated at certain concentration of AS-ODN-SMP or AS-ODN for 8 h at 4 degrees C or 37 degrees C. Then the fluorescence oligodeoxynucleotide- labeled cells were counted by flow cytometer and the intracellular fluorescence intensity was determined after incubated with chloroquine for 2 h.

RESULTSCellular uptake of oligodeoxynucleotides was significantly increased following application of AS-ODN-SMP and total intracellular fluorescence intensity was enhanced by 683 folds with the vehicle concentration of 20 microg x mL(-1). AS-ODN-SMP entranced to cells profoundly with temperature-dependent manner. Rare cells took on fluorescence when incubated at 4 degrees C, while 37 degrees C they were significantly increased. But the intracellular fluorescence intensity appeared same level in present or absent of chloroquine.

CONCLUSIONWith the help of polyacrylate submicroparticles, oligonucleotides efficiently entranced the cells via endocytosis and could successfully escape the degradation in lysosome.

Objective: To investigate the changes of gene expression in CD34+ hematopoietic stem and progenitor cells (HSPCs) under different growth environments. Methods: Umbilical cord blood mononuclear cells (UCB MNCs) were cultured in static and stirred systems. After 7 days of culture, CD34+ cells were isolated and total RNA was extracted. Gene expression patterns of CD34+ cells from fresh, static and stirred cultures were compared using differential display (DD). Results: 30 gene fragments displayed differential expression levels based on the conditions of DD. One of differentially expressed genes was identified as RAN, which is a member of oncogene RAS family. This gene may be associated with proliferation of hematopoietic cells. Conclusion: Different growth environments induced differential gene expression patterns of CD34+ HSPCs. These differentially expressed genes would give new insights into optimizing in vitro environments for expanding hematopoietic cells.
