Objective To study the effect of sodium hyaluronate(SH) on cornea preservation to provide a basis for eyes banks cornea preservation. Methods SH was applied in the short-term and middle-term cornea preservation. The preservation effect was evaluated by corneal morphology, trypan blue-alizarin red staining, activity assay of SDH and G-6-P enzymes, and ultrastructural observation of corneal endothelium. Results The above indices were obviously better in the experiment group than in the control group (P

Objective To assess the relationship between maternal plasma tumor necrosis factor-related apoptosis-inducing ligand ( TRAIL ) before 20 weeks′gestation and hypertensive disorder complicating pregnancy (HDCP);and to evaluate the predictive value of plasma TRAIL for HDCP.Methods A 2-phase screening/validation study was designed.In the screening phase , a nested, case-controlled study was performed , the plasma samples collected before 20 weeks′gestation from 20 women who later developed HDCP and 20 age-and gestation week-matched controls were tested in prospective screening test for protein expression profiling during pregnancy and HDCP.Plasma samples were analyzed by a human protein microarray technology designed to detect 507 proteins simultaneously.Differently expressed proteins′functional annotation and clustering were performed by using of Database for Annotation , Visualization and Integrated Discovery ( DAVID) and Gene Ontology ( GO) database.The TRAIL level of plasma samples obtained before 20 weeks′gestation from 53 women who later developed HDCP and 106 similarly matched controls were further validated by ELISA and 62 clinical risk factors were investigated.Logistic regression and ROC analysis were used to evaluate the relationship between TRAIL and HDCP and its predictive value for HDCP.Results In protein microarray analysis , 23 proteins expressed differently before 20 weeks′gestation between the two groups.Further validation results showed that TRAIL levels in HDCP patients were lower significantly (45.7 ±13.1) pg/ml than those in healthy pregnant controls (51.2 ±14.7)pg/ml, P=0.021.Multiple factor logistic regression analysis of 159 pregnancies showed that three features were finally entering the logistic model, they were:anemia (OR=4.87, 95% CI 1.05-24.26), pre-pregnancy BMI (OR=1.72, 95% CI 1.35 -2.19) and TRAIL (OR=0.96, 95% CI 0.92 -0.99).The predictive accuracy of logistic model was 81.8%.The model significantly increases the predictive value (AUC=0.81, 95%CI 0.73-0.87) compared to TRAIL as independent predictor (AUC=0.59, 95%CI 0.51-0.67).Conclusions Totally 23 proteins were expressed differentially before 20 weeks′gestation in plasma of women who later developed HDCP , confirming that HDCP is a heterogeneous disease with different biological changes.The data suggests that plasma TRAIL levels relate with the development of HDCP and its combination with pre-pregnancy BMI and anemia have a high predictive value for HDCP before 20 weeks′gestation.

Objective To investigate the roles of sodium hyaluronate (SH) in the preservation of corneas. Methods Referred to M-K prescription Preserving liquid MMK was employed as the control. Different concentrations of SH added into the preserving liquid MMK were employed as the experiment groups: group Ⅰ (0.05% SH), group Ⅱ (0.03% SH), and group Ⅲ (0.01%). At 3, 5, 7, and 10 d after preservation in the preserving liquids, the ultrastuctures of the rabbit corneas were observed by scan electron microscopy and light microscopy, the corneas were stained by typan blue alizarin red staining, and the activities of SDH and G-6-P were detected by enzymohistochemistry. Results There was difference in macrostructure of the corneas in each group. Morphological changes in group Ⅰ were not obvious, but those in the control group were remarkable. Trypan blue-alizarin red staining indicated the highest vitality of corneal endothelial cells (CECs) in group Ⅰ, but the lowest in the control group. In addition, the activities of SDH and G-6-P in each group were significantly different. Conclusion The addition of SH in reformed M-K liquid can prolong the duration of the mid-term preserved corneas and the protective effect is in a dose-dependent manner.

Objective To establish the dissolution curves test method of Ribavirin capsules, and investigate dissolution behavior of domestic Ribavirin capsules.To provide experimental basis for generic drugs quality consistency evaluation.Methods According to the first dissolution method (basket method)stated in appendix Ⅹof Chinese Pharmacopeia(2010 edition),the rotation speed was 50 r/min with dissolution medium volume of 900 mL.The dissolution profiles of Ribavirin capsules in four different mediums( pH 1.2 hydrochloric acid solution,pH 4.5 acetic buffer,pH 6.8 phosphate buffer and water) were determined by HPLC.The determination was performed on C18 column with mobile phase consisted of 4 g/L sodium dihydrogen phosphate solution(pH adjusted to 5.0 ±0.05 using 5% sodium hydroxide solution)-acetonitrile(98:2)at the flow rate of 1.0 mL/min.The detection wavelength was 225 nm,and sample size was 10μL.Results The linear range of ribavirin was 2.5-200μg/mL(r=1).RSD of precision and stability tests were lower than 0.5%.The average recoveries were 101.3%, 100.7%, 100.2%, 100.4% in four mediums.Dissolution behavior of capsules can be more consistent and rapid dissolution in pH4.5 and pH6.8 mediums.But they were quite different in pH1.2 and water mediums, and some of their average dissolution at 15 min could not reach 85%.Conclusion This method is accurate and reliable.There is a difference between domestic Ribavirin capsules dissolution behavior, and the formulation processes have room for improvement.

Objective To explore diagnosis-related groups(DRGs) case mixes and development approaches for medicare expense standard fitting patients with respiratory system diseases in Sichuan province.Methods 280 717 cases of respiratory system diseases were sampled from the homepages of medical records of general hospitals in Sichuan.These cases were grouped by means of the exhaustive chi-square automatic interaction detector in the decision tree model and the medicare costs standard was derived using the relative-ratio weighting coefficient.Results The main classification nodes of respiratory diseases were age and patient clinical complexity level (PCCL).Patients were classified into 158 disease diagnosis related groups, including 122 DRGs of internal medicine and 36 DRGs in surgical medicine.The max relative-ratio weighting coefficient was 14.04 and the min one was 0.29.And the extreme inpatients' expenses can affect the identification of classification nodes, calculation of relative weighting coefficient and medicare cost standard.Conclusions Large sample size is advantageous in establishing DRGs and calculating the medicare costs standard based on relative-ratio weighting coefficient.It is however imperative to strengthen monitoring on extreme inpatients' costs and control the homepage quality of medical records.

OBJECTIVE:To study the effects of Salvionolic acids dialyzate on anaphylatoxin,C-reactive protein(CRP),interleukin-6(IL-6)and tumor necrosis factor-?(TNF-?)in peripheral blood of patients with maintenance hemodialysis(MHD)and to discuss whether the Salvionolic acids dialyzate could improve the blood-membrane biocompatibility.METHODS:Thirty-six patients undergoing MHD for at least half a year were randomly divided into 3 groups:control group(conventional hemodialysis,n=12),low-dose group(dialysate with salvionolic acids 40 mg?L-1,n=12)and high-dose group(dialysate with Salvionolic acids 80 mg?L-1,n=12).Dialyzer of the polysulfone membranes was firstly used in all patients.Patients' blood sampling was scheduled before dialysis,30 minutes after dialysis and at the end of dialysis(5 minutes before withdrawal of dialyzer)for measurement of serum levels of complement(C3a,C5a),CRP,IL-6 and TNF-? using enzyme linked immunosorbent assay(ELISA).RESULTS:As compared with before dialysis,the levels of C3a and C5a in both control group and low-dose group were evidently increased at 30 minutes,while the difference in high-dose group was nonsignificant.No significant differences of IL-6 and TNF-? were found between pre-dialysis and post-dialysis in three groups.As compared with before dialysis,the concentration of CRP in control and low-dose groups obviously increased but decreased obviously in high-dose group after dialysis.CONCLUSION:The production of C3a,C5a and CRP in the process of hemodialysis could be inhibited by a certain dose of Salvionolic acids dialyzate,which can improve the biocompatibility of the dialysis-membrane to some degree,but can't improve the levels of IL-6 and TNF-? after single-time dialysis.
