OBJECTIVE:To regulate the management of operation drug and promote medication security. METHODS:Based on the relevant principles in the standard of JCI,the practice about establishment of operation pharmacy in our hospital was intro-duced,and it were stated from two aspects which included working mode and effects. RESULTS:The working mode were format-ed by definiting the duties and working flow of pharmacist,anesthetist and liaison man. The establishment of operation pharmacy, which brought operation drugs into the unified management system of our hospital,saved manpower and improved work efficien-cy,refined the management of drugs in all aspects,improved the management of drug safety level,strengthened drug expiration date management,implemented the reporting of adverse drug reactions(event)and collecting of medication(potential)errors. The established mode conformed to the relative standard of JCI including preparation,grant,storage and collection of ADR of drug. CONCLUSIONS:The established drug management of operation pharmacy promotes standardized administration of surgery drug, which guarantees the drug use safety of patients.

Objective To develop a microsphere-based suspension array for simultaneous detec-tion and identification of Salmonella H antigens by using Luminex xTAG technology and to evaluate its capa-bility in serotyping Salmonella strains. Methods The fliC and fljB genes, encoding the H antigen of Salmo-nella, were selected as the target genes. Universal upstream primers were designed based on the highly con-served regions of fliC and fljB genes, and the corresponding specific reverse primers were designed based on the variable regions. While synthesizing, the 5′end of each upstream primer was labeled with biotin and the 5′end of each specific reverse primer was modified with its certain TAG sequence. After amplified and la-beled with biotin and TAG sequence, the PCR products of specimens were hybridized with the mixture of va-rious MagPlex-xTAGTM microspheres. Each set of microspheres contained its unique anti-TAG sequences. The results of hybridization were analyzed by using Luminex MagPix reader system and the median fluores-cence intensity ( MFI) was reported. The H antigens of 145 Salmonella strains were identified with this de-veloped xTAG suspension array, and the results were compared with those obtained by using traditional ser-um agglutination test. Results The PCR products of different H antigens ranged from 94 bp to 245 bp and could be identified by hybridizing with MagPlex-xTAGTM microspheres. There was no cross-reaction between different H antigens or with DNAs derived from Escherichia coli, Vibrio cholerae, Vibrio parahaemolyticus and Shigella flexneri. Compared with the traditional serum agglutination test, the sensitivity and specificity of the xTAG suspension array in the identification of H antigens of 145 Salmonella strains were 95. 1% and 100%, respectively. Conclusion The developed xTAG suspension array was a specific, accurate and effective method for simultaneous detection and identification of 31 H antigens of common Salmonella serovars strains. It could be used for determining the H antigens of more than 90 Salmonella strains within 5 hours.

Objective To study the variation and characteristics of HIV-1 tat exon 1 gene from a patient with AIDS dementia complex( ADC), so as to research the pathogenesis of ADC. Methods The tat gene was amplified with nested PCR from genomic DNA which was extracted from lymph node, spleen and different brain tissues( meninges, grey matter from frontal cortex, white matter from frontal cortex, temporal cortex and basal ganglia) of a patient who died of ADC. PCR products were cloned into the pGEM-T vector,after transformation and selection by ampicillin and blue/white spotting. Five of positive clones were sequenced. HIV-1 tat sequences were processed with BioEdit and MEGA4. With the softwares, Neighbor-Joining tree, p-Distances, values of ds/dn, and analysis of amino acid motifs were all done. Results The samples were all identified as HIV-1 B and genetic variation exists in HIV-1 tat isolated from different tissue;Compared with HXB2, sixteen sites of the amino acid seque nce coded by the HIV-1 tat gene which was isolated from the patient changed. In addition, part of the changes were different between periphery and brain,especially, the five Q54R changes from basal ganglia and one Q54R change from temporal cortex are deserve to follow with interest. Conclusion Variations exist in the HIV-1 tat genes extracted from the ADC patient and the variations from peripheral and central nerve tissues were different, whether the variations concerned with the pathogenesis of ADC need more research.

OBJECTIVETo study the hemodynamics of the pulmonary artery (PA) in pulmonary artery hypertension (PAH).

METHODSWith combined clinical hemodynamic measurements and CT data, the 3D model of PA and its branches was reconstructed to obtain the real 3D geometric structure of PA and its branches. Computational fluid dynamics (CFD) simulation was carried out for the reconstructed 3D geometric model of the PA and its branches with Womersley velocity as main pulmonary entrance conditions; then hemodynamic parameters of the PA and its branches in cardiac cycle were calculated and the changes of flow field, pressure, wall shear stress (WSS) at different times, and its impact on physiological processes were analyzed.

RESULTSimulation showed that the pressure of the main PA and the branches of the left and right PA was higher in the systolic period than that in the diastolic period; especially, the that of right PA and its interlobular artery was significantly higher than that of the left. The blood flow velocity of the main PA and its branches of right and left PA was significant different, the velocity was much higher at the distal of the right PA than that at the left. High WSS field formed at the proximal of the right PA before the branches during the systolic.

CONCLUSIONThe right PA at the proximal and lower lobe artery are affected by much larger pressure and change firstly, so the change of morphological and functional of theses segments will be have more important value to prompt existence of the early PAH.

AIM:To investigate the effects of 1.8mm coaxial micro incision phacoemulsification on corneal endothelial injury and postoperative visual acuity.METHODS: Totally 145 eyes in 120 patients underwent phacoemulsification from July 2013 to July 2015 were randomly divided into observation group 60 cases (73 eyes) and control group 60 cases (72 eyes).The observation group 60 cases were given 1.8mm coaxial micro incision cataract phacoemulsification operation,while the control group were given traditional 3.2mm coaxial micro incision cataract surgery.The uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA),corneal thickness of incision area,incision width,incision length,macular retinal thickness,surgically induced astigmatism,corneal endothelial cell counts and complications of the two groups were compared.RESULTS: The UCVA and BCVA on 1wk after surgery of the observation group were significantly higher than the control group (t=3.604,7.109;P<0.05);the width of incision on 1wk and 1mo after surgery of the observation group were significantly less than the control group (t=205.3,225.2;P<0.05).The length of incision in observation group was significantly greater than the control group (t=3.926,5.009;P<0.05).Macular retinal thickness 1wk after surgery of the observation group was significantly less than the control group (t=2.817,P<0.05).The surgically induced astigmatism was significantly less than the control group (t=19.43,22.16;P<0.01);the difference of corneal edema between the two groups was not significant (8.22% vs 11.11%) (x2=0.348,P>0.05).CONCLUSION: The 1.8mm micro incision phacoemulsification is helpful to improve the visual acuity of patients with cataract phacoemulsification,which may be related to the reduction of corneal cell injury,enhancement of corneal closure and decrease post-operation corneal original astigmatism.

Objective To measure and define the distribution of left gastric lymph nodes.Meth- ods From Jan.2004 to Apr.2005,silver clips were set around the root of the left gastric artery in 124 pa- tients with esophageal and gastric cardia carcinoma,X-ray films at 0?and 90?simulator gantry in the radio- therapeutic position were taken.Then,the data of the superior,lower,left,right,anterior and posterior bor- der in each patient was recorded.With SAS 8.02 software,data of minimum area which covered the left gas- tric lymph node in different incidences were obtained.Results According to the analysis of Shapiro- Wilk,Kolmogorov-Smimov,Cramer-von Mises and Anderson-Darling tests,each border was of normal distri- bution,with equal frequency in the male and female,despite the actual results in different genders.Pearson Correlation Coefficients analysis did not suggest a significant relationship between the border and height, weight and size of vertebrae,which formed the minimum area covering the left gastric area at frequency of 100%,95%,90% and 85%,which were drawn out through the calculation.Conclusions Aiming at completely identifying the normal distribution of the left gastric lymph node,more patients are required to be in the pool.For the time being,location in the left gastric area can be obtained from details of the results in the present study.

Objective To assess the diagnostic value of combined testing of urinary bladder cancer antigen(UBC),hyaluronic acid(HA)and survivin in the detection of bladder cancer.Methods This study included 64 bladder cancer patients and 20 urinary benign disease patients.The examinations of urine UBC by enzyme-linked immunosorbent assay(ELISA),HA by radioimmunology assay,survivin by RT-PCR and urine cytology were performed in them.Results The sensitivity of UBC(85.9%,55/64),HA (89.1%,57/64)and survivin(93.8%,60/64)was significantly higher than that of urine cytology (40.6%,P＜0.01).The specificity of UBC,HA,survivin and urine cytology was 85.0%(17/20),80.0% (16/20),95.0%(19/20)and 95.0%(19/20),respectively;there was no significant difference among these 4 methods(P＞0.05).The sensitivity of UBC,HA and survivin was also significantly higher than that of urine cytology in different histologic stages and grades(P＜0.05).The sensitivity of UBC and survivin was not significantly different among different histologie stages and grades(P＞0.05).With regard to HA test, the sensitivity in G_2 and G_3 groups was significantly higher than G_1 group(P＜0.01),but there was no differ- ence between G_2 and G_3 groups(P＞0.05);and no difference among different histologic stages(P＞0.05). However,the sensitivity of cytology was improved with the higher grade of bladder cancer(P＜0.01);there was no difference among histologic stages(P＞0.05),By combined use of UBC,HA and survivin,both the sensitivity and specificity were 100%.Conclusions The study indicates that UBC,HA and survivin are better diagnostic markers for the early detection of urinary bladder cancer.These tests are simple,feasible and noninvasive with higher sensitivity and specificity.In addition,combined use of them can improve the diag- nostic sensitivity and specificity.
