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.

ObjectiveTo observe the effect of cluster needling of scalp acupuncture combined with rehabilitation(Tang's Approach) on interleukin-4 (IL-4), T lymphocyte subsets of immunosuppressive model rat.Methods40 healthy SD rats (male, 200～250 g) was divided into 5 groups randomly: normal group (NG), model group (MG), acupuncture group(AG), rehabilitation group(RG), and acupuncture with rehabilitation group(ARG), 8 rats in each group. Each group was treated by acupuncture or rehabilitation except the model or normal group, once a day for 10 d. Radioimmunoassay and malondialdehydein (MDA) technique were used to test the contents of IL-4 and T lymphocyte subsets in each group. ResultsThe contents of IL-4 of immunosuppressive rats can decrease significantly in RG and ARG (P＜0.05). The level of CD4+ T lymphocyte increased more significantly in AG and RAG than in MG after the treatment (P＜0.01). ConclusionTang's Approach can decrease the contents of IL-4 and improve the level of CD4+ T lymphocyte in rats.

[Objective] To discuss the reasonable treatment and skil of gal bladder calculus.[Method] Select 81 cases of such patients, take their clinical data as examples for analysis foundation;and choose relative documents for evidence of theoretic analysis.[Result] 77 cases were successively operated of laparo-scope, 3 transferred for laparotomy owing to difficult anatomy of Colot triangle, 1 made probe of choledoch because of choledocholithiasis;compared with documents results, the incision length, bleeding, operaiotn time, in-hospital time and complications of laparoscope operation, transferred laparotomy in the study were similar to relative documentary reports, the differences had no statistical meaning;the intranperative bleeding, operation period, in-hopital time, complications were better than documents, the differences had statistical meaning. [Conclusion] The correct pre-operation evaluation of disease condition, operation chance and methods selection, 3 operation points were the key of successful operaiton.

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.
