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.

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 toxic effects of rotenone on dopamine transporter in the substantia nigra of the rat. Methods Rats (male) were divided into normal control group, vehicle control group and rotenone experimental group(1.0mg/kg and 1.5mg/kg). The animals were subcutaneously administrated with the vehicle or rotenone in different dosage once a day for 28 days. One day after last injection, the brain was dissected and the substantia nigra was harvested. Protein expressions of tyrosine hydroxylase and dopamine transporter were determined with the methods of immunohistochemistry and Western blot. The mRNA expressions of dopamine transporter and dopamine receptor were detected with RT-PCR respectively. The activity of Na+-K+-ATPase was assayed biochemically. Results In the experimental groups, both the immune positive neurons of tyrosine hydroxylase and the expression of its protein were significantly decreased in the substantia nigra of the rats after rotenone treatment. The number of dopamine transporter antibody-immune positive neurons were significantly increased in the rats exposed to rotenone. Furthermore, protein and mRNA expressions of dopamine transporter in the experimental group were also obviously up-regulated compared with the normal control group. A decreased activity of Na+-K+-ATPase was observed in the substantia nigra of rats in the rotenone experimental group. In addition, the mRNA expression of D2R was also increased in contrast with that in the control group. Conclusions Rotenone is toxic to dopamine neurons in the substantia nigra of rats. Dysfunction of dopamine transporter may be involved in the mechanism of rotenone toxicity to dopamine neurons.
