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.

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 Sirolimus was Withdrawn in 2 cases due to its sideeffect.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 explore the prognostic factors of non-small-cell lung cancer (NSCLC) patients with brain metastasis. Methods 122 NSCLC patients with brain metastasis from Jan 2007 to Dec 2012 were incorporated, and followed with death as the end. The influence factors of prognosis were retrospective analyzed. Kaplan-Meier method was used for survival analysis, the Log-rank test for single factor analysis,and Cox regression model for multiple factors analysis. Results The single-factor and multi-factor analysis showed that the influence factors of prognosis were age, pathological type, number of intracranial metastasis, presence of extracranial metastasis, treatment, Karnofsky score, the original site control situation (P<0.05). Gender, the size of the original site had no influence for prognosis (P>0.05). The average survival times of patients with palliative symptomatic treatment, simple whole brain radiotherapy, whole brain radiotherapy local lesion plus the amount of radiation, whole brain radiotherapy local lesion plus the amount of radiation combined with chemotherapy were (2.14 ±0.19) months, (7.28 ±0.60) months, (16.90 ±1.35) months, (17.7±1.12) months, 1 year survival rates were 0, 8.5%, 71.0%, 93.3%. Survival analysis showed that there was statistical significance among the four groups (P= 0.000). Conclusion The age, pathological type, number of intracranial metastasis, presence of extracranial metastasis, treatment, Karnofsky score, the original site control situation are the prognosis factors in NSCLC patients with brain metastasis, therefore the treatment of these patients should be comprehensively analyzed.

BACKGROUND:Posterior cervical open-door expansive laminoplasty is one of the simple and effective methods to treat cervical spinal diseases, has satisfactory results but low complications. However, the imbalance of sagittal plan, loss of lordosis or axial pain is often reported recently. OBJECTVE:To analyze the correlation between cervical sagittal alignment and clinical outcomes after laminoplasty. METHODS:Between January 2011 and June 2015, 122 cases of cervical spinal disease, who were treated with open-door expansive laminoplasty with mini-titanium plate, were retrospectively analyzed. Clinical outcomes were evaluated by Japanese Orthopaedic Association, Neck Disability Index and Visual Analogue Scale. Radiographic results were assessed by C2-7 Cobb angle, C2-7 sagittal vertical axis and C7 slope. The correlation between sagittal alignment and clinical outcomes were analyzed. RESULTS AND CONCLUSION:(1) Al patients were fol owed up for 7-32 months. (2) Japanese Orthopaedic Association, Neck Disability Index and Visual Analogue Scale scores were improved in the final fol ow-up (al P<0.001). No significant difference in upper limb Visual Analogue Scale scores was determined (P=0.142). In the final fol ow-up, C2-7 sagittal vertical axis increased (P=0.036), but neither the C2-7 Cobb angle nor the C7 slope significantly changed (P=0.092, P=0.184). (3) There were no correlations between sagittal alignment parameters (C2-7 Cobb angle, C2-7 sagittal vertical axis and C7 slope) and clinical outcomes (Japanese Orthopaedic Association, Neck Disability Index and Visual Analogue Scale) (al P>0.05). (4) These findings indicated that posterior cervical open-door expansive laminoplasty with mini-titanium plate can significantly improve the neurological function of patients. However, there is no correlation between cervical sagittal alignment and clinical outcomes.

OBJECTIVE: To develop a set of consummated comprehensive application platform that meets the actual demand so as to promote hospital treatment level and pharmaceutical care quality.METHODS: The protocol and standard meeting the international standard was adopted for system design.The currently popular combination tools(Apache+PHP+MySQL) set was developed and an open information resources management system and multi-structured architecture were established.RESULTS & CONCLUSIONS: This system is practical,advanced and safe and it is composed of 5 modules: drug inquiry system,rational drug use system,management on adverse drug reactions,pharmacy administrative management and network management.The system can not only guarantee the compatibility and the expandability of system,but also meet the needs of the development of hospital pharmacy and effectively enhance the rational drug use.

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.

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.
