OBJECTIVETo compare therapeutic effects of herb-partitioned spread moxibustion and western medicine on chronic nonspecific ulcerative colitis.

METHODSSixty cases were randomly divided into a spread moxibustion group (n = 28) and a western medicine group (n = 32). The spread moxibustion group was treated with herb-partitioned spread moxibustion at lower limb around stomach meridian, abdomen region around Guanyuan (CV 4) and lower Jiaji (EX B 2) points; and the western medicine group was treated with oral administration of Sulfasalazine. Their therapeutic effects were observed after treatment.

RESULTSThe cured-markedly effective rate was 71.4% (20/ 28) in the spread moxibustion group, and 25.0% (8/32) in the western medicine group, the former was better than the latter (P < 0.05).

CONCLUSIONSThe therapeutic effect of herb-partitioned spread moxibustion for treatment of chronic nonspecific ulcerative colitis is better than that of the oral administration of Sulfasalazine with less adverse reaction, and is worth popularizing in clinic.

OBJECTIVETo study the impact of left varicocele (VC) and varicocelectomy (VCT) on the apoptosis of spermatogenic cells and the levels of nitrogen monoxidum (NO) and interleukin 1 (IL-1) in the rat testis.

METHODSWe randomly divided 60 adolescent male SD rats into four groups of equal number: sham operation control, VC model 1 (VC1), VC model 2 (VC2), and VCT. We determined the semen quality and levels of NO and IL-1 in the testis tissue, detected the apoptosis of spermatogenic cells by TUNEL, and compared the indexes obtained among different groups.

RESULTSAn experimental VC model was successfully established by partially ligating the left renal vein of the rats. Sperm concentration and motility were significantly decreased in the VC1 ([1.54 ± 1.16] x 10⁶/ml and [44.23 ± 15.46]%) as compared with those in the sham operation group ([2.80 ± 1.62] x 10⁶/ml and [72.34 ± 12.62]%) (P < 0.05), but remarkably higher in the VCT ([1.82 ± 1.34] x 10⁶/mI and [51.21 ± 12.62]%) than in the VC2 group ([1.04 ± 1.21] x 10⁶/ml and [39.23 ± 13.21]%) (P < 0.05). The levels of NO and IL-1 in the left testes were markedly elevated in the VC1 ([0.172 ± 0.030] ng/ml and [1.468 ± 0.080 ] mg/ml) in comparison with those in the sham operation group ([0.134 ± 0.021] ng/ml and [0.782 ± 0.079 ] mg/ml) (P < 0.05), and significantly higher in the VC2 ([0.198 ± 0.020] ng/ml and [1.994 ± 0.090] mg/ml) than in the VCT group ([0.141 ± 0.010] ng/ml and [0.781 ± 0.036] mg/ml) (P < 0.05). However, the NO and IL-1 levels in the right testis showed no statistically significant differences between the two groups, and the two levels were positively correlated (r = 0.492, P < 0.01). The rats of the VC1 group exhibited remarkable apoptosis of spermatogenic cells in the bilateral testes, with significant differences in the apoptosis index ( AL) between the two sides (P < 0.05) as well as in the same side in comparison with the sham operation group (P < 0.01). The Als of spermatogenic cells in the bilateral testes showed statistically significant differences in the VCT (P < 0.05) but not in the VC2 group (P > 0.05), and those in the same side manifested dramatic differences between the VCT and VC2 groups (P < 0.01).

CONCLUSIONVaricocele induces changes of the NO and IL-1 levels in the testis tissue and increases the apoptosis of spermatogenic cells, which might be one of the causes of testis damage and spermatogenic dysfunction.

OBJECTIVETo explore the stimulation of human hepatic stellate cells by Cytochrome P4502E1-mediated oxidative stress.

METHODSHepG2-line was transfected with human CYP2E1 plasmid (HepG2/CYP2E1) and empty plasmid (HepG2/PCI) respectively. The CYP2E1 expression was evaluated with RT-PCR and Western blot. MDA was measured in culture medium of HepG2 cell lines. LX2 was co-incubated with HepG2/CYP2E1, HepG2/PCI and HepG2 respectively. The level of hydroxyproline in culture medium was examined in 48 hours and the cells were lysated and total RNA and protein were extracted. COL-1 and MMP2 mRNA levels were detected by RT-PCR and analyzed semi-quantitatively. PICP proteins were measured by ELISA. Zymography was performed to investigate MMP2 enzymatic activities.

RESULTS(1) MDA from the HepG2 which (HepG2/CYP2E1)express human CYP2E1 (6.51+/-0.25) was significantly higher than that from the HepG2 which do not (HepG2/PCI) express human CYP2E1 (3.07+/-0.29) and HepG2 alone (2.57+/-0.29). (F=22.66, all P<0.01). (2) After co-incubated for 48 hours,the level of hydroxyproline in culture medium (35.24+/-3.52) excreted from CYP2E1/LX2 could significantly increase (F=58.89, P is less than 0.01). PICP protein (540.01+/-11.38) excreted from CYP2E1/LX2 was significantly increased (F=124.97, P<0.01). Zymography showed MMP2 gene expression and enzymatic activities of MMP2 had no difference among the groups (F=0.29, P>0.05) (F=0.33, P>0.05).

CONCLUSIONSCYP2E1 derived oxidative stress mediated stimulation of collagen I synthesis by hepatic stellate cells. Hydroxyproline excreted by LX2 was increased by CYP2E1. COL-1mRNA had no difference among the groups (F=0.73, P>0.05).
