Objective To compare the efficacy, adverse reactions and cost-effectiveness between domestic pantoprazole (Pan Li Su) and imported omeprazole (Losec) in the treatment of non-steroidal anti-inflammatory drugs (NSAID) associated ulcer bleeding.Methods Fifty-eight hospitalized patients with NSAID associated ulcer bleeding were randomly divided into pantoprazole group (n=31)and omeprazole group (n= 27) according to random number table.Pantoprazole group was given 40 mg domestic pantoprazole dissolved 100 ml 0.9% sodium chloride solution intravenously every 12 hours.Omeprazde group was given 40 mg omeprazole dissolved in 100 ml 0.9% sodium chloride solution intravenously every 12 hours.The two groups were both treated for seven days.Finally, the efficacy and adverse effect were observed, and cost-effectiveness was analyzed with pharmacoeconomics.Results The total effective rate of pantoprazole group was 93.5%, omeprazole group was 96.3% .The drugs of the two groups could effectively stop bleeding, the difference was not statistically significant (P= 1.00).The rate of adverse effect was 3.2 % and 7.4 % in the two groups accordingly.The cost-effectiveness ratio (C/E) was 7.76 and 20.73 respectively.Compared with pantoprazole group, the incremental cost-effectiveness ratio of omeprazole group was 454.Conclusions Domesic pantoprazole is an effective, safety and economical medicine for NSAID associated ulcer bleeding.

Objective:To evaluate the antimicrobial effectiveness of Zhenzhu Mingmu eye drops according to the requirements de-scribed in Chinese pharmacopoeia (2010 edition). Methods:Totally 7 batches of Zhenzhu Mingmu eye drops from 7 enterprises were evaluated. All the samples were tested according to the requirements described in Chinese pharmacopoeia, and the testing points of 6h and 24h were added. Results:As for bacteria, the reduction value of staphylococcus aureus in 7 days treated with Zhenzhu Mingmu eye drops from enterprise e was 0. 61g, and that in 14 days was 1. 01g. That in 7 days treated with the eye drops from the other enter-prises was all above 1. 01g, that in 14 days was above 3. 01g, and that in 14-28 days kept stable. As for fungi, the number was stable from the beginning with the treatment of the eye drops from the seven enterprises. Conclusion:Although the type and content of bacte-riostatic agent in domastic Zhenzhu Mingmu eye drops are the same, there is difference in the antimicrobial effectiveness of the product from different enterprise. The eye drops from one enterprise can't meet the requirements for type I product described in Chinese pharma-copoeia,and the others meet the requirements.

Objective To analyze mutations in the GJB2 gene in a Chinese patient with keratitis-ichthyosis-deafness (KID)syndrome complicated by cutaneous squamous cell carcinoma. Methods Clinical data were collected from a patient with KID syndrome complicated by cutaneous squamous cell carcinoma. Peripheral blood samples were obtained from the patient and her parents, and DNA was extracted from these blood samples. PCR was performed to amplify the exon 2 of the GJB2 gene followed by direct DNA sequencing. Results A mutation (c.148G > A)was identified at position 148 in exon 2 of the GJB2 gene, which caused a codon change from GAC to AAC and resulted in the substitution of aspartate by asparagine at position 50 in the connexin26 (Cx26)protein (p.Asp50Asn). Inaddition,anothermutation(c. 79G > A), which led to the substitution of valine by isoleucine at codon 27 in Cx26 (p.Val27Ile), was found at position 79 in exon 2 of the GJB2 gene. Neither of the two mutations was detected in the patient′s parents. Literature review revealed that 13 cases of KID syndrome complicated by cutaneous squamous cell carcinoma had been reported in abroad, and the mutation c.148G > A was detected in the GJB2 gene in all the 7 cases finally diagnosed by gene sequencing. Conclusion GJB2 gene mutations may be responsible for the clinical phenotype of KID syndrome in this Chinese patient, and the mutation c.148G > A may be related to the development of cutaneous squamous cell carcinoma.

Background Diabetic retinopathy (DR) is a progressive vision-threatening complication of diabetes mellitus (DM),but its pathogenic mechanism is still unclear.Researches showed that growth arrest-specific gene product 6 (Gas6) /TAM system participates in pathogenesis and development of DR,and stromal-derived factors (SDF) vary in 2-type DM patients.However,whether Gas6/TAM and SDF-1 are associated with DR is below understood.Objective This study was to determine the relationship between the staging of DR and the levels of serum Gas6,SDF-1α and SDF-1β in DM patients.Methods A prospective cohord study was designed in this study.Ninety 2-type DM patients were included in the 3rd Affiliated Hospital of Southern Medical University Hospital from January to August in 2013.The patients were grouped into the non-diabetic retinopathy (NDR) group,background DR group (BDR) and proliferative DR (PDR) group,with 30 for each group.Thirty normal volunteers were enrolled in the same hospital and same period.The periphery blood 2 ml was collected from all the subjects under the consent inform.The levels of serum Gas6,SDF-1α and SDF-1β were assayed by ELISA,and leukocytes,neutrophils,plasma triglycerides (TG),total cholesterol (CHOL),high density lipoprotein cholesterol (H DL-C) and low density lipoprotein cholesterol (LDL-C) levels were detected and compared among the 4 groups.The correlations of serum Gas6,SDF-1 α and SDF-1 β changes with blood inflammatory cells and blood lipid were analyzed.Results The plasma CHOL concentrations were 4.93(4.14,5.44),5.02(4.35,5.69),4.54(3.85,5.93) and 5.99(5.11,6.89)mmol/L in the normal control group,NDR group,BDR group and PDR group,respectively,and the blood CHOL concentrations were significantly higher in the PDR group than those of the normal control group,NDR group,BDR group (P =0.002,P =0.007,P =0.006).White blood cell counts in the normal control group,BDR group were higher than those of the PDR group (P =0.034,P =0.015),neutrophil counts in the BDR group were higher than those of the PDR group (P =0.024),HDL-C in the NDR group was higher than that in the PDR group (P =0.032).LDL-C in the PDR group was higher than that in the normal control group.Compared with the normal control group,serum Gas6 levels were significantly lower in the NDR group and BDR group (P =0.048,P =0.006),and the serum Gas6 level showed an insignificant increase in the PDR group in comparison with BDR group (P =0.297).Serum SDF-1α levels in the PDR group was significantly higher than that in the BDR group (P =0.033) ;serum SDF-1β levels in the PDR group,BDR group were significantly higher than that in the NDR group (P =0.011,P =0.008) and normal control group (P =0.030,P =0.002).Weaker positive correlation was observed between the serum Gas6 and CHOL,TG,LDL-C levels (r=0.285,r=0.200,r=0.241,all at P＜0.05),between SDF-1α and SDF-1β (r=0.190,P＜0.05) as well as between SDF-1β and white blood cell (r=0.183,P＜0.05).Serum Gas6 served as dependent variable,while white blood cell,neutrophil,CHOL,TG,HDL-C,LDL-C,SDF-1α,SDF-1β served as independent variables,multiple stepwise regression analysis showed Gas6 =170.791 + 5.283CHOL (F =5.021,P =0.027).Conclusions Serum Gas6,SDF-1α and SDF-1β probably participate in the development of DR in 2-type diabetic patients.Gas6,SDF-1 α,SDF-1 β may play roles by affecting blood glucose level,angiogenesis,inflammatory cells and blood lipid metabolism.

Objective To construct and purify the recombinant protein of platelet-activating factor acetylhydrolase(PAF-AH) isoformⅠ,and study the enzyme activity by different substrates. Methods The ? subunit of PAF-AH isoformⅠwas cloned and expressed in E.coli.Exogenously expressed recombinant protein was purified to SDS-PAGE homogeneity,and its activity was identified by arylesterase detection.Phenylacetate,l-O-hexadecyl-2-deoxy-2-thioacetyl-sn-glycero-3-phosphocholine(2-Thio PAF) and 1-myristoyl-2-(4-nitrophenylsuccinyl) phosphatidylcholine(the latter two were commercial plasma PAF-AH substrates) were used for the substrate identification.The plasma type PAF-AH was served as positive control. Results Recombinant protein of ? subunit of PAF-AH isoformⅠwas successfully constructed and expressed in E.coli after purification.Compared with positive control,the recombinant protein could hydrolyze phenylacetate and 2-Thio PAF,but could not hydrolyze 1-myristoyl-2-(4-nitrophenylsuccinyl) phosphatidylcholine.Conclusion Recombinant protein of ? subunit of PAF-AH isoformⅠcan be successfully constructed.There are differences in the substrate specification to the two commercial PAF substrates for PAF-AH isoformⅠand plasma type PAF-AH,which provides a quick method to differentiate PAF-AH isoformⅠfrom plasma type PAF-AH.

To evaluate the neuroprotective effect of nerve growth factor ( NGF ) on acute angle-closure glaucoma patients after trabeculetomy.METHODS: Patients with viral keratitis who underwent trabeculectomy in treatment of acute angle - closure glaucoma in Xiamen Eye Center of Xiamen University from December 2011 to October 2013 were selected and completed the treatment, 61 eyes of 45 cases were followed up. The treatment group of 23 cases (32 eyes) with acute angle-closure glaucoma patients were treated by NGF gel for 3mo after trabeculetomy, while in the control group 22 cases (29 eyes) were treated by normal saline replaced NGF. All patients were followed up for at least 12mo, visual acuity, perimetry, retinal nerve fiber layer ( RNFL) thickness and cup/disc ratio of the patients were followed up during the treatment. The safety of topical use of NGF gel was also evaluated.RESULTS:ln all patients, the intraocular pressure ( lOP) was successfully controlled under 21mmHg and the visual acuity was markedly increased in the affected eye after trabeculectomy. Compared with control group, the postoperative lOP and visual acuity had no significant differences in treatment group (P>0. 05). The average light sensitivity of perimetry and mean defect were better than that in control group postoperative 6 and 12mo; The results of optical coherent tomography ( OCT ) and Heiderburg Retina Tomography ( HRT )-Ⅲ showed that RNFL thickness was significantly greater than that in control group, while cup/disc ratio significantly less than that in control group postoperative 6 and 12mo. Ocular surface damage, corneal endothelium to reduce and other eye complication were no observed in treatment group.CONCLUSlON:Acute angle-closure glaucoma treated by NGF gel after operation is effective and safe.

Objective To study the discrepancy influence of the sulbactam content on susceptibility testing results of cefoperazone/sulbactam combination disks.Methods Agar dilution method was used to determine MICs of cefoperazone,cefoperazone/sulbactam(2:1 and 1:1),and disk diffusion was used to detect the zone diameters of cefoperazone,cefoperazone/sulbactam(75/30 and 75/75μg/disk)disks against 534 clinical gram-negative isolates.The discrepancy within the results of MICs,zore diameters,the method of agar dilution and disk diffusion was analyzed.Results By standard agar dilution method,MIC_(50) of cefoperazone,cefoperazone/sulbactam(2:1 and 1:1)were 32,16,16μg/ml,and MIC_(90) of those were ≥256.128,64 μg/ml respectively.No statistic discrepancy was found for MICs between the ratios of 2:1 and 1:1 combination by Wilcoxon ranks test(Z=-0.248,P=0.804).Susceptibility rate,resistance rate,and intermediate rate with 75/30μg disk were 55.3%,24.5%and 20.2%respectively,which were similar to those determined by agar dilution method.Susceptibility rate,resistance rate,and intermediate rate(I%)with 75/75μg disk were 72.5%,12.4% and 15.1% respectively,compared with the susceptibility rate from 75/30μg disk was 17.2% higher.Statistic discrepancy were tested by paired t-test (t=21.613,P＜0.01)with two groups of whole strains' zone diameters from 75/30μg and 75/75μg disks,and resulting in the difference of susceptibility or resistance rates for ESBL-producing strains,Acinetobacter bauamnnii and Enterobacteriaceae without ESBL tested isolates.On the contrary,for Pseudomonas aeruginosa,Stenotrophomonas maltophilia and ESBL negative isolates,the zone diameters discrepancy was not statistically significant between the results from 75/30μg and 75/75μg disks.Conclusions There is no statistic discrepancy between the susceptibility results from cefoperazone/sulbactam(2:1 or 1:1 ratios)in dilution method and in diffusion method with 75/30μg disk.When the 75/75μg disk is used to be tested for ESBL-producing strains,Acinetobacter bauamnnii and other Enterobacteriaceae,the results should be shown with sulbactam content.

Aim To observe the effect of eplerenone(EPL) and Chinese decoction on cell apoptosis in obstructive nephropathy rats.Methods Sixty male Wistar rats were randomly divided into sham group, UUO group, EPL group and ZY group(n=15).Except sham group, the rats in the other groups were ligated with unilateral ureteral obstruction(UUO) for renal interstitial fibrosis model.The rats were treated with eplerenone at 100 mg·kg-1·d-1 added to diet in EPL group, and orally 13.7 g·kg-1·d-1 decoction of Chinese medicine in ZY group.The kidneys were harvested on 14th day, the number of renal cell apoptosis were detected by TUNEL, and serum aldosterone and 8-OhdG were detected with radioimmunoassay and ELISA.Caspase-12, caspase-9, Bax and Bcl-2 were examined by immunohistochemistry and Western blot.Results The levels of serum aldosterone, serum and urine 8-OhdG and the number of positive apoptotic cells increased significantly in UUO rats compared with Sham group.The overexpression of caspase-9, caspase-12 and Bax and down-regulated Bcl-2 were obvious in UUO group(P<0.01).The level of 8-OhdG, expression of caspase-9, caspase-12 and Bax were down-regulated, and Bcl-2 expression was up-regulated in eplerenone and Chinese decoction treated rats(P<0.01).Conclusion Eplerenone and Chinese decoction could inhibit cell apoptosis induced by oxidative damage after UUO via caspases and(or) Bax pathway.
