Objective:To design and prepare repaglinide and metformin hydrochloride tablets for pilot scale test and industrial pro-duction. Methods:Dissolution was applied to optimize the formula and preparation process. Results: The tablets were prepared ac-cording to the determined formula and process with poloxamer 188, meglumine, PVP K30, croscarmellose sodium, microcrystalline cellulose PH101, sorbitol, magnesium stearate and coating powder as the adjuvants. The dissolution behavior of the tablets in four media was similar to that of the reference. Conclusion:The preparation process of repaglinide and metformin hydrochloride tablets is simple and feasible, and the quality is controllable and stable.

ObjectiveTo evaluate the efficacy and safety of Sirolimus (SRL) in immunosuppression following liver transplantation. Methods SRL was applied in 21 patients totally.Indication for adoption was Tac-related nephrotoxicity (4/21), suspiciously Tac-related hepatoxicity (8/21), Tac overdose (3/21), renal insufficiency pre-operation (2/21), or cancer (4/21). Median follow-up was 25. 4 months. Results SRL provided an adequate prophylaxis against rejection in all study patients, with one case of acute rejection. Sirolimus was Withdrawn in 2 cases due to its sideeffect. Tat-induced hepatoxicity in 6 cases and nephrotoxicity in 3 cases were relieved significantly.Conclusions SRL given alone appears to be an effective primary immunosuppressant regimen fororthotopic liver transplantation patients. Early conversion contributes to significant improvement of Tac-related hepatoxicity and nephrotoxicity.

Objective　To investigate the effect of ipratropi um bromide and atropine on airway mucin hypersecretion in the chronic bronchiti s model of rats. Methods　The model was established by intratrac heal instillation of small dose of lipopolysaccaride (200 μg) ipratropium bromi de and atropine were administrated 3-21 d after the model was established. Patho logical changes, mucin in bronchoalveolar lavage fluid (BALF) and tracheal ring culture medium were examined before and after the adnsinistration of iprat ropium bromide and atropine. Results　Characteristic pathologica l manifestions of chronic brochitis were found after instillation of LPS. Sig nificant decrease in the number of tracheal epithelia goblet cells, secretion of mucin were observed in ipratropium bromide and atropine treated rats. The eff ect of inhibiting the secretion of mucin of ipratropium bromide was higher than atropine. Conclusion　It suggests that muscarinic acetylcholine receptor plays an important role in airway mucin hypersecretion in chronic bro nchitis model of rat. Ipratropium bromide exhibit a stronger inhibition effect on mucin hypersecretion than atropine, moreover no inhibition effect on mucocil iary clearance which was observed in atropine.

Objective To investigate the relationship between truncating mutations of APC gene and sporadic colorectal cancer,and analyze the feasibility of non-radioactive protein truncation test (PTT) in the detection of mutations of APC gene.Methods Ninety-six samples of sporadic colorectal cancer tissues ( including 44 patients with colonic cancer and 52 patients with rectal cancer) were obtained from the General Hospital of Ningxia Medical University from September 2008 to September 2010.The mutation cluster region of the APC gene was screened using digital PTT labeled with fluorescent Lys-t-RNA,with a polymerase chain reaction fragment amplified from genomic DNA serving as a tenplate for in vitro translation.The occurrence of gene mutation was determined according to the emergence of truncated peptides.The mutation cluster region of the APC gene in 46 samples of colorectal cancer tissues was analyzed by direct sequencing.The detection rates of the 2 methods were compared by chi-square test.Results Thirteen (26％) truncated peptides were detected in the 50 samples of colorectal cancer tissues.The mutation type of 4 samples is nonsense mutation,which resulted in emergence of truncated gene products.Eleven (24％) truncated peptides were detected in the 46 samples of colorectal cancer tissues.There was no significant difference in the detection rates between PTT and direct sequencing ( x2 =0.033,P ＞ 0.05 ).Conclusions Truncating mutations of APC gene are common alterations in sporadic colorectal cancer in the Chinese.Digital PTT labeled with fluorescent Lys-t-RNA is rapid and high-sensitive in screening gene mutations.

OBJECTIVETo explore the rhythm regulatory mechanism of interleukin-6 (IL-6) in the process of moxibustion for rheumatoid arthritis (RA).

METHODSA total of 144 Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group, a moxibustion group, a sham operation group, an operation group, an operation+moxibustion group, 24 rats in each one. Each group was divided into 4 time points (0:00 am, 6:00' am, 12:00 am, 6:00 pm), 6 rats in each time point. The Light-Dark 12 : 12 was given in all rats for light-dark cycle. Except the blank group, rats in the remaining groups were treated with intracutaneous injection of freund's complete adjuvant at right-side foot to establish the model of RA. After the model establishment, bilateral adrenal, glands were removed in the operation group and operation + moxibustion group, while those in the sham operation group were not removed with identical operation procedure. Rats in the moxibustion group and operation + moxibustion group were treated with grain-sized moxibustion from 7:00 am to 9:00 am at "Shenshu" (BL 23) and "Zusanli" (ST 36) once everyday, 6 times were taken as one session and 3 sessions were required tatclly, while rats in the remaining groups received identical fixation without moxibustion. The general health state and foot volume of rats were measured before model establishment, after establishment and after treatment. After treatment, rats were sacrificed at each time point to collect the blood sample and measure the content of IL-6 by using enzymne-immunoassay method.

RESULTSCompared with the blank group, the foot swelling in the model group was obviously increased (P<0. 05); the IL-6 maintained circadian rhythm (P<0. 05), but the peak phase had a backward trend, famplitude had an increased trend and the median was significantly lifted (P<0. 05). Compared with model group, !the foot swelling in the moxibustion group was obviously decreased (P<0. 05); the IL-6 maintained circadian. rhythm (P<0. 05), and the peak phase had a forward trend, amplitude had a decreased trend and the median was significantly reduced (P<0. 05). Compared with the moxibustion group, the foot swelling in the operation--moxibustion group was obviously increased (P < 0.05); the IL-6 maintained circadian rhythm (P < 0.5), but the peak phase moved forwrd, and the median was significantly elevated (P < 0.05).

CONCLUSIONThe IL-6 in plasma maintains significant pathological circadian rhythm in RA rats; with the complete hypothalamic-pituitary-adrenal axis, moxibustion is likely to regulate the circadian rhythm of IL-6 to play an important role of anti-inflammatory effect in RA rats.
