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.

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.

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.

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.

The factor of antiapoptosis in cancer is recently identified as survivin. Survivin is prominently overexpressed in embryonic and fetal tissues, and various human cancers. It is potentially involved in both inhibition of apoptosis and control of cell division. Recently, survivin is found to be correlated with the genesis, progress, and prognosis of urological cancer. Manipulation of the antiapoptotic pathway maintained by survivin may be beneficial for cancer therapy. Progressive research of survivin in urological cancer.

OBJECTIVE To investigate the distribution and drug resistance of the bacteria encountered from the(clinical) infection,and provide reference for the rational use of agents in clinics.METHODS To culture the(specimens) from inpatient and outpatient clinic from Dec 2004 to Mar 2005,and perform the drug (sensitivity) test.RESULTS In 1584 isolated strains,the first four were coagulase negative Staphylococcus((15.6%),) Klebsiella(13.0%),Escherichia coli(10.0%),and Candida albicans(9.9%).The highest resistance of Gram(-negative) bacilli was to ampicillin(86.7%),then to cephalothin(79.5%),and mezlocillin(75.7%);G~-bacilli were(sensitive) to meropenem(2.3%),piperacillin/tazobactam(19.0%),and fosfomycin(29.1%).Gram~+ cocci had drug(resistance) to 18 antibacterials except vancomycin,MRSA was higher than MSSA;(Enterococcus) faecium showed poor sensitive rate to penicillin and erythromycin.CONCLUSIONS We should give more attantion to the Rules on Antibacterials in Clinical Application and use drugs reasonably.

Objective To assess the efficacy and safety of transurethral bipolar plasmakinetic resection of the prostate(TUPKRP) for the treatment of benign prostatic hyperplasia(BPH).Methods The operation was completed using a bipolar plasmakinetic resection system(CIRCON ACMI).Three trenches were created at 5,7,and 12 o'clock position,respectively,to divide the middle,left,and right lobes of the prostate gland for resection.The bladder neck was widened in overlapping vaporizing swathes to create a wide-necked funnel down to the level of the surgical capsule.The apical tissue was resected to the anterior border of the seminal colliculus.With a F_(20) or F_(22) three-cavity catheter indwelling for 3~5 d,normal saline irrigation was used for 1~2 d postoperatively.Results The duration of the procedure was 20~180 min(53.2?28.7 min),and resected tissue weighed 8~130 g(23.5?21.6 g).The intraoperative blood loss was 10~300 ml(65.4?46.8 ml) and no blood transfusion was required.No perforation of the prostatic capsule or transurethral resection syndrome occurred.The peak urinary flow rate(Qmax) increased from 8.4?1.9 ml/s preoperatively to 18.4?1.8 ml/s 1 month postoperatively(q=55.498,P﹤0.05).The residual urine(RU) decreased from 80.8?59.7 ml preoperatively to 19.5?10.0 ml postoperatively(q=17.287,P﹤0.05). The international prostate symptom score(IPSS) decreased from 25.7?5.5 preoperatively to 5.7?2.4 postoperatively(q=52.969,P﹤0.05).The scores of quality of life(QOL) decreased from 4.4?1.0 preoperatively to 1.1?0.2 postoperatively(q=42.146,P﹤0.05). Conclusions Transurethral bipolar plasmakinetic resection of the prostate for the treatment of benign prostatic hyperplasia is effective and safe,with few complications.

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.
