The self-book renewing information in medical library was classified, which showed that the 3 months in a year and the period in a day with the largest number of readers who visited the medical library Website were characterized by their rigid need. In addition, the evidence was provided for the issuing time of information on li-brary information issuing platform in order to optimize the popularizing effect of library.

AIM:To explore the clinical effect of capsule membrane phacoemulsification and capsular bag in phacoemulsification in treatment of hard nuclear cataract with high myopia.
METHODS:A total of 297 patients(322 eyes) with hard nucleus cataract(Ⅳ-Ⅴ grade nucleus) and high myopia were selected from Mar. 2014 to Mar. 2016 in our hospital. They were randomly divided into the observation group with 149 cases(162 eyes) and the control group with 148 cases(160 eyes). The observation group received capsule membrane phacoemulsification and the control group received capsular bag in phacoemulsification. The therapeutic effect and safety of patients in two groups were compared. The comparison of phacoemulsification time, energy parameters and corneal endothelial cell density used t-test, post-operative visual acuity and the occurrence of complications were tested by Chi-square test.
RESULTS: The harder the nucleus was, the longer the phacoemulsification time and higher the average phacoemulsification energy was, and the differences were statistically significant(P<0. 05). The phacoemulsification time and energy parameters of the observation group were significantly lower than that of the control group( P<0. 05 ). One month after operation, the postoperative visual acuity in two groups was significantly higher than the visual acuity at 1d after operation(P<0. 05). But there was no statistical significance on the visual acuity at 1mo after operation between two groups ( P> 0. 05 ). After operation, the density of corneal endothelial cell in two groups was significantly lower than the density before operation ( P < 0. 05 ). But there was no statistical significance on the density of corneal endothelial cell after operation between two groups ( P > 0. 05 ). The intraoperative complication rate of observation group was significantly lower than that of the control group ( P<0.05 ) , but there was no statistical significance on postoperative complication rate between two groups ( P>0. 05). CONCLUSION: For the treatment of hard nuclear cataract with high myopia, capsule membrane phacoemulsification and capsular bag in phacoemulsification have similar effect, but capsule membrane phacoemulsification has better safety.

Neuroimaging technology is the major means in the study of cerebral blood flow. This article reviews all kinds of neuroimaging technologies in identification of perihematomal penumbra in intracerebral hemorrhage,as well as the research status of perihematomal cerebral blood flow in intracerebral hemorrhage.

Endophytic fungi which reside in the tissue of mangrove plants seem to play an important role in the discovery of new biologically active substances. During the course of screening for the antimicrobial metabolites from the endophytic fugus Penicillium sp. FJ-1 of mangrove plant Avicennia marina, a new aurone glycoside (1) was isolated by repeated column chromatography on silica gel and recrystallization methods. The structure of 1 was elucidated as (Z)-7,4'-dimethoxy-6-hydroxy-aurone-4-O-β-glucopyranoside, on the basis of spectroscopic analysis. Compound 1 exhibited antifungal activity against Candida sp., with the potency comparable to amphotericin B and much better than fluconazole. Compound 1 can also inhibit extracellular phospholipase secretion in a concentration-dependent manner.

Objective To construct short-hairpin RNA (shRNA) eukaryotic express vectors targeting of insulin like growth factor-1 receptor (IGF1R) gene, and to explore the changes of adhesion, invasion and FAK protein expression of MHCC-97 H hepatocellular carcinoma cells with RNA interference. Methods The shRNA oligonucleotide fragments were designed and synthesized based on the sequence of IGF1R mRNA. Double strands were formed after annealing and inserted into pGCsi-U6-Neo-GFP vector. The recombinant was transformed into Stable 3, then plasmids were extracted and identified by restriction enzyme and sequencing analysis. The most effective vectors were selected by RT-PCR and Western blotting after transfecting 293T cells. The best one was used to transform MHCC-97H cells which were selected with G418 to obtain positive colons. The changes of adhesion, invasion and FAK protein expression in MHCC-97H cells were studied. Results The restriction enzyme analysis and sequencing analysis demonstrated that shRNA had been inserted into vectors, and their sequences were the same as the design. It was indicated by RT-PCR and Western blotting that the silencing efficacy of IGF1R was 88%. The ability of adhesion and invasion significantly decreased after IGF1R silencing in MHCC-97H cells, and so was the expression of FAK protein. Conclusion IGF1R pGCsi-U6-Neo-GFP shRNA can significantly decrease the abilities of adhesion and invasion in MHCC-97H cells, and inhibit the expression of FAK protein.

Objective To investigate the accuracy of contrast enhanced ultrasound (CEUS) in diagnosing acute severe panereatitis.Methods Thirty three patients with acute severe pancreatitis were enrolled in the study and all of them underwent CEUS and spiral computed tomography(CT) scan.CT was taken as gold standard in acute severe pancreatitis diagnosis.CEUS were done within 72 hours after CT scan.Results Compared with CT, the sensitivity, specificity,accuracy, positive predictive value,and negative predictive value of CEUS for detecting the necrosis of pancreas were 90%, 95%, 94%, 90% and 95%respectively.The sensitivity, specificity, accuracy, positive predictive value,and negative predictive value of CEUS in diagnosing severe acute pancreatitis were 85%, 92%, 88%, 94% and 80% respectively, while 37% ,86% ,58%, 78%, 50% for conventional ultrasound respectively.Conclusions CEUS is accurate in detection of pancreatic necrosis and diagnosis of acute severe pancreatitis.

Objective To explore the application effect of quality control for medical records of clinical pathway .Methods The 127 clinical pathway patients with acute ST segment elevation myocardial infarction were randomly divided into two groups .69 patients with clinical pathway quality control were taken as test group , while 58 patients without clinical pathway quality control were taken as control group.The hospitalization duration, total hospitalization expenses and various events expenses were compared between these two groups.Results The average hospitalization duration in test group was (10.32 ±2.03) days, while that in control group was (12.10 ±2.96) days, with statistically significant differences between the groups (p<0.05).The average hospitalization ex-pense in the test group was (52,349.94 ±16,944.22) yuan, while that in control group was (59,522.81 ±22,783.01) yuan, with statistically significant differences between the groups (p<0.05).Among various events of hospitalization expense, the medicine cost and nursing fee in the test group were lower than those in control group, with statistically significant differences (p<0.05), and no statistically significant differences were found in the other items (p>0.05).Conclusion The quality control for medical records of clinical pathway can effectively control the hospitalization duration and hospitalization expense , standardizing the implementation of clinical pathway.
