Aim To investigate the Clotrimazoles (CLT) inhibitive effect on the secretion of ?-defensins of the Paneth cells.Methods The ?-defensin mRNA expression is determined by semi-quantitative RT-PCR. The secretion of defensins is determined by dot-blot and ELISA. Results CLT has no influence on the defensin mRNA expression. All of 125 nmol?L -1, 250 nmol?L -1 and 500 nmol?L -1 CLT can inhibit the secretion of ?-defensins. Conclusion CLT could inhibit the secretion of defensins, which suggests that CLT maybe influence the function of small intestine

Objective On the basis that olfactory ensheathing cells (OECs) transplanted into injured spinal cord may facilitate axonal regeneration, the OECs were cultured from olfactory bulb and nasal olfactory mucosa in the present study, in order to explore if the olfactory mucosa could be a new donation for transplanting the olfactory ensheathing cells. Methods OECs were harvested from olfactory bulb and mucosa based on the differing rates of attachment of the various cell types, following GFAP and NGFRp75 immunocytochemistry. Results Three morphological and immunohistochmically distinct types of cell which appeared bipolar,tripolar and flat morphology were present in primary cultures of adult rat olfactory bulb and olfactory mucosa.Conclusion The method of purification for OECs based on the different rates of attachment among the various cell types is simple, inexpensive and practical. The OECs from nasal olfactory mucosa like ones from the olfactory bulb is an accessible source of tissue for autologous grafting in human spinal paralegia in the future.

OBJECTIVETo investigate whether the genistein can increase the radiosensitizing effect on laryngeal squamous carcinoma Hep-2 cells.METHODS Hep-2 cells were treated with genistein, radiation, and genistein plus radiation respectively. DMSO was used as the control group. EdU assay was performed to assess the short-term effect of genistein and (or) radiation on the proliferation of Hep-2 cells. Clonegenic assay was used to detect the survival rate of Hep-2 cells after treatment with radiation doses of 0, 2, 4, 6, 8 Gy and radiation combined with genistein. The data was fitted into the classic single-hit multi-target mathematical model to analyze the long-term effect on cell proliferation death of Hep-2 cells.RESULTSIt was observed that radiation combined with genistein could significantly inhibit the proliferation of Hep-2 cells. And the SER of 10μmol/L genistein was 1.412.CONCLUTIONGenistein can inhibit the proliferation of Hep-2 cells by DNA synthesis inhibition, and can be an adjunct agent of radiotherapy.

Objective To explore the expression of interleukin 13(IL-13) mRNA in peripheral blood mononuclear cells (PBMCs) and its association with serum C-reaction protein(CRP) in patients with ulcerative colitis(UC). Methods IL-13 mRNA expression in PBMCs was detected by RT-PCR in patients with UC(21 cases of active UC and 10 cases of quiescent UC)and 20 healthy subjects. At the same time, the serum level of CRP was detected by ELISA. Results The expression level of IL-13 mRNA in PBMCs of patients with active UC was significantly lower than that in PBMCs of patients with quiescent UC and healthy subjects (6.45?1.23 vs 14.72?2.12 or 15.17?2.38,P0.05). The expression level of IL-13 mRNA in PBMCs of active UC patients was negative correlation with serum level of CRP (r=-0.589,P

Objective To assess the role of matrix metalloproteinase-9(MMP-9) and interleukin-6 (IL-6) of amniotic fluid (AF) in predicting infection of amniotic cavity. Methods Eighty-four cases of sigle foetus women with premature delivery, premature rupture of foetal membranes,or suspicious infection of amnitotic cavity were enrolled in this study. AF was obtained by transabdominal amniocentesis before starting any treatment.Infection of amniotic cavity was defined when AF bacterial culture was positive. The contents of glucose, leukocytes, MMP-9,and IF-6 in AF were determined. Results The levels of MMP-9 and IL-6 in AF were significantly higher in women with infection of amniotic cavity than those in women without. In women with infection of amniotic cavity, MMP-9 level was significantly correlated with IL-6 level (r=0.813,P

Retinopathy of prematurity (ROP) is a potentially blinding retinal vascular disease that occurs in premature infants and low birth weight infants.Along with the development of perinatal medicine,the incidence of ROP has increased.If infants with ROP could get treatment in time,the disability rate due to ROP would significantly reduce.Now,the present situation and advances in treatment of ROP were reviewed.

Objective To summarize the experience of HIV/AIDS preventive interventions among out-of-school teenagers and provide scientific evidence for the development of large-scale interventions in the future. Method Using both non-random snowball and cluster sampling approach,a total of 5,000 participants were selected from 7 provinces (9 provincial sites ) and a cross-sectional survey was conducted by employing a semi-open-ended self-administrative interview schedule to evaluate their behavioral change before and after the interventions. Results The rate of HIV related knowledge and condom use increased significantly among the participants. For instance,the rate of condom use when having sex at the last time increased by 34.86%,i.e. from 27.67% at the baseline to 59.88% after the intervention (?2=34,86,P

Objective To investigate the effects of radix salvia miltiorrhizae on the apoptosis of hepatoeytes during cold preservation and reperfusion injury in rat donor liver. Methods Forty male SD rats were divided into experimental group, control group and sham operation group. The rat model of liver transplantation was established according to the Kamada method. The grafts were preserved in lactated Ringer's solution with radix salvia miltiorrhizae in experimental group and in lactated Ringer's solution in control group for 5 hours, then they were transplanted orthotopically. Six hours after transplantation, the recipients were sacrificed, and the serum ALT and AST were detected by automatic biochemistry analyzer, the hepatocyte apoptosis by TUNEL, the expression of Bcl-2 and FasL protein by flow cytometry. The histopathological changes of the liver grafts were observed under light microscope. Results The levels of ALT and AST in the experimental group were significantly lower than those in the control group after reperfusion. Compared with that in the control group, the apoptosis index of the hepatoeyte was signifieandy decreased in the experimental group ( F = 133.802, P <0.05 ), while the level of Bel-2 protein expression was increased ( F = 91.063, P < 0.01 ). No statistical difference upon FasL protein expression was detected between the 2 groups( F = 1.329, P >0.05). The histopathological injury of the liver grafts in the experimental group was significantly slighter than that in the control group. Conclusions Radix salvia mihiorrhizae inhibits the apoptosis of hepatocytes by increasing the Bcl-2 protein expression during cold preservation and reperfusion injury, so it has a protective effect on the liver graft against ischemia reperfusion injury.
