For understanding the effect of MDG-1, a water-soluble β-D-fructan polysaccharide from Ophiopogon japonicas, on intestinal microecological balance, especially on the changes of lactobacillus, sixty 8-week-old male C57BL/6J mice were given a high-fat diet for six weeks and were also gavaged with saline once a day simultaneously. Then the mice which is below 30 grams or dropped more than 10% through lavage were eliminated and the rest were randomly divided into four groups: diet-induced obese (DIO) model group (n = 12, gavaged with saline), low-dose MDG-1 group (n = 12, gavaged with MDG-1, 75 mg · kg(-1)) , medial-dose MDG- 1 group (n = 12, gavaged with 150 mg · kg(-1)), and high-dose MDG-1 group (n = 12, gavaged with 300 mg · kg(-1)) according to the weight and blood glucose; the model group and MDG-1 group were placed on a high-fat diet while the normal control group (n = 12, gavaged with saline) were kept on a low-fat diet through the experiment. After 12-weeks of treatment, feces samples were collected and cultured for intestinal microecological balance analysis. Then the intestinal probiotics were cultured through traditional methods combined with modified gradient gel electrophoresis (DGGE) method. The changes of lactobacillus in each treatment group were also detected by a statistical analysis of the total number of the intestinal flora. We have established the phylogenetic tree by 16S rDNA sequencing and use some molecular identification methods such as PCR-DGGE to analyse the changes of the dominant bacteria floras, and also get the pure culture. In conclusion, different concentrations of MDG-1 can increase the number of the intestinal probiotics, especially Taiwan lactobacillus and Lactobacillus murinus, and improve their diversity and promote proliferation in a dose-dependent way.

Objective To investigated the efficacy of celecoxib for postoperative analgesia after endoscopic nasal surgery. Methods One hundred and twenty ASA Ⅰ or Ⅱ patients of both sexes aged 18-64 yr were randomly assigned to one of three groups ( n = 40 each): control group ( group C); celecoxib 200 group ( group CEL1 ) and celecoxib 400 group ( group CEL2 ). The patients took celecoxib 200 and 400 mg by mouth at 1 h before induction of anesthesia in group CEL1 and CEL2 respectively. Anesthesia was induced with midazolam,propofol, remifentanil and rocuronium and maintained with iv propofol and remifentanil infusion. VAS was used to assess postoperative pain (0 = no pain, 10 = worst pain). In PACU when VAS score ≥3, the patients were given fentany125 μg iv every 5-10 min until the VAS score < 3. After being discharged from PACU, the patients received celecoxib 200 mg every 12 h for 5 days in the 2 celecoxib groups. Oxycodone 5 mg was used as rescue analgesic when VAS score ≥ 4 until the VAS score < 4. The number of patients who needed fentanyl for analgesia in PACU, the number of patients who needed oxycodone within 6 h, 6-24 h and day 2-5 after operation and side effects after operation were recorded. Analgesic efficacy was assessed at day 5 after operation and the satisfactory rate of patients calculated. Blood samples were obtained at 0, 6 and 48 h after operation for determination of PGE2,6-k-PGF1α and TXB2 concentrations. TXB2/6-k-PGF1α was calculated. Results The number of patients who needed fentanyl in PACU and the number of patients who needed oxycodone within 6 h and 6-24 h after operation were less, the satisfactory rate was significantly higher, and PGE2 concentrations in blood were significantly lower at 48 h after operation in the 2 celecoxib groups than in group C ( P < 0.05 or 0.01 ). There was no significant difference in each index between the 2 celecoxib groups ( P > 0.05 ). There was no significant difference in TXB2/6-k-PGF1α at each time point among the three groups. Nausea and vomiting occurred in one patient after operation in group C, but side effects were not observed in the 2 celecoxib groups. Conclusion Celecoxib given before and after operation can effectively relieve postoperative pain after endoscopic nasal operation by reducing PGE2 concentrations in blood.

Objective To observe the immunosuppression function of a novel HLA-derived peptide, RDP1258, after rat renal transplantation in vivo.Methods Peptides were synthesized by Fmoc chemistry method. The rat renal heterotopic transplantation model (n=32) was established. The allograft rats were divided into 4 group: group A (n=8) receiving subtherapeutic CsA+RDP1258 peptide; group B (n=8) receiving RDP1258 alone; group C (n=8) receiving subtherapeutic CsA alone; and group D (n=8) receiving no immunosuppression. The renal allograft survival days of receptor rats were observed. Serum creatinine was measured and color Doppler flow imaging was checked. Renal tissues were harvested for light microscopic examination. The immunologic tolerance status of rat renal allografts was detected by MLR of 60th day receptor rat spleen cells cultured with the donor spleen cells and the third party.Results The allograft survival time in groups A, B, C and D were ( 63.4?30.6)days, (18.3?7.3)days, (16.9?6.4)days and (9.4?2.6)days, with the difference being significant between group A and other three groups. The results of MLR revealed that a hyporesponsiveness to donor occurred while the normal reaction to the third parity was retained.Conclusion A novel HLA derived peptide therapy combined with a sub-therapeutic dose of CsA significantly prolonged allograft survival days, and the mechanism might be that RDP1258 induced a donor-specific immunologic tolerance status in the recipients.
