RESUMEN
OBJECTIVE: To evaluate the efficacy and safety of wuling Capsule combined with Pinaverium Bromide in treatment of irritable bowel syndrome (IBS). METHODS: Sixty-four IBS patients were randomized into two groups, the treatment group and the control group, 32 in each group. Patients in the treatment group took wuling Capsule (0. 33 g/capsule, 3 times per day) and Pinaverium Bromide (50 mg/tablet, one tablet each time, 3 times per day) , while those in the control group only took Pinaverium Bromide (50 mg/tablet, one tablet each time, 3 times per day). The therapeutic course for all was 6 weeks. IBS symptom score questionnaire, IBS-Quality of Life (IBS-QOL) , Self-Rating Depression Scale (SDS) , and Self-Rating Anxiety Scale (SAS) were assessed before and after treatment. Adverse reactions were also observed. RESULTS: The improvement of abdominal pain, stool frequency, and stool properties, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). The improvement of dysphoria, body image, concerns for health, and dietary restriction of IBS-QOL, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). The improvement of SDS and SAS, as well as changing rates of integrals were significantly higher in the treatment group than in the control group (P <0. 05). No severe adverse reaction occurred in either group. CONCLUSION: Combination therapy of wuling Capsule and Pinaverium Bromide could improve abdominal pain and defecation, attenuate depression and anxiety of IBS patients with higher safety.

To establish fibroblast cell lines from different tissues and to compare the biological characteristics of those cell lines, five fibroblast cell lines derived from Chinese swamp buffalo (Bubalus bubalis) were selected for comparative assays. Cell style and survival rate (before cryogenic preservation and after recovery) were tested, and karyotype, patterns of isoenzymes of lactic dehydrogenase, malic dehydrogenase, and cell cycle were analyzed. These cell lines had a healthy morphology with a typical spindle shape, and assessment of cell style showed these cells to be very pure fibroblasts. Cell growth curves showed a typical "S" shape. Results of microorganism contamination assays were negative, and isoenzyme analysis showed no cross-contamination. The number of chromosomes (2n) of swamp buffalo is 48. Between 28% and 46% of the cells were 2n, and cell apoptosis was not pronounced at 20th generation. Results showed that skin fibroblasts were more adaptable to tissue culture conditions than the ones from kidneys and ear margin, and they are more suitable for cellular manipulation in Chinese swamp buffalo.

Summary Reprogramming of DNA methylation in somatic cell nuclear transfer (SCNT) embryos is incomplete, and aberrant DNA methylation patterns are related to the inefficiency of SCNT. To facilitate nuclear reprogramming, this study investigated the effect of treating Guangxi Bama minipig donor cells with trichostatin A (TSA), 5-aza-2'-deoxycytine (5-aza-dC), or combination of TSA and 5-aza-dC prior to nuclear transfer. Analyses showed that there were no major changes in cell-cycle status among all groups. We monitored the transcription of DNMT1, DNMT3a, HDAC1 and IGF2 genes in donor cells. Transcription levels of HDAC1 were decreased significantly after treatment with a combination of TSA and 5-aza-dC, along with a significantly increased level of IGF2 (P < 0.05). Although treatment of donor cells with either TSA or 5-aza-dC alone resulted in non-significant effects in blastocyst formation rate and DNA methylation levels, a combination of TSA and 5-aza-dC significantly improved the development rates of minipig SCNT embryos to blastocyst (25.6% vs. 16.0%, P < 0.05). This change was accompanied by decreased levels of DNA methylation in somatic cells and blastocyst (P < 0.05). Thus in combination with TSA, lower concentrations of 5-aza-dC may produce a potent demethylating activity, and lead to the significantly enhanced blastocyst development percentage of Bama minipig SCNT embryos.
