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.

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 compare the relationship of acceptable noise level (ANL) between monaural and binaural hearing aid in patients with bilateral moderate-to-severe hearing loss, and to investigate the clinical significance of the ANL in binaural hearing aid fitting and the predictive role in the hearing aid effect assessment.Methods A total of 15 patients with bilateral moderate-to-severe hearing loss were selected, and the most comfortable levels (MCL), background noise level (BNL) and calculate ANL were tested, respectively, in 4 conditions: without hearing aids, fitted only left ears, fitted only right ears and binaural fitting.Results The ANL in 15 subjects measured at 4 conditions were 18.87±5.26, 12.60±2.47, 12.00±2.90, and 5.13±1.25 dB S/N, respectively.The MCLs were 80.40±9.28, 63.73±5.15, 62.27±5.36, and 61.80±6.05 dB HL, respectively.The BNLs were 61.67±6.14, 51.13±3.94, 50.27±4.50, and 56.67±5.16 dB HL.The ANL difference between the only left and right fitting groups was not statistically significant(P>0.05).The ANL difference between the monaural or the binaural hearing aid group and without hearing aids group were statistically significant (P<0.05), respectively.Compared with the monaural hearing aid group, the binaural hearing aid group had significantly lower ANL(P<0.05).Conclusion For people with bilateral hearing loss, hearing aids can improve their ability to manage the background noise, and binaural hearing aid fitting is better than monaural.

Objective To evaluate the effect of one stage resection combined with chemotherapy for the treatment of colorectal cancer with hepatic metastasis.Methods In this study 17 out of 36 colorectal cancer patients with hepatic metastasis underwent one stage tumor resection embolization and chemotherapy via hepatic artery and portal vein through pumps in 10 cases. The remaining 19 cases in which metastatic tumors judged as nonresectable received embolization and chemotherapy alcohol injection and electrothermotherapy for the metastatic tumors.Results Recurrence developed in 6 out of 7 patients not receiving primary combined embolization and chemotherapy. The diameter of tumors in the 19 patients decrased by 57% on average, among which 4 patients underwent secondary resection of the metastatic tumors. The 1,2,3 year′s survival rate was 94%, 82%, 65% in combined group, and 74%, 53%, 32%(P

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.

Objective To analyse the failed total hip arthroplasty(THA) and to improve its long term results. Methods Thirty five patients(36 hips) undergone revision THA from November 1996 to April 1999, were grouped according to the different causes of the primary failed THA. Results Statistical analysis failed to show the factors related to the failures. In any one failed case, the causes were usually more then one item. The most common causes of failed surgery found in 24 cases were aseptic loosening and peri prosthetic osteolysis, wear out of acetabulum was seen in 7, malpositioned prostheses in 6 and postoperative dislocation in 3. Infection and fracture of femoral stem happened in 3 and 2 patients respectively. Conclusion THA has been extensively used as an effective procedure for the reconstruction of hip joint. Long term excellent clinical results are related to strict selection of indications, appropriate prosthesis, and finally the experience and surgical technique of the surgeon are also of importance to the final outcome.
