OBJECTIVE To explore the rational application of aminoglycosides antibiotics.METHODS We randomly selected 520 patients' records of applying aminoglycosides antibiotics from Jan to Dec in 2007.Types of antibiotics,dosages,usage,ways of delivery and periods and combination of medicines were analyzed.RESULTS Out of the 520 cases,the oldest patient was 89 year and the youngest one was 7 years.The application rate of amikacin was the highest(35.6%),which was delivered mainly by iv,the combination of medicines accounted for 92.7%.CONCLUSIONS The application of aminoglycosides antibiotics in our hospital is basically rational.In some cases the improper antibiotics are used and the duration is a little longer,which should be supervised.

Objective To investigate the effects of pyrrolidine dithiocarbamate(PDTC) on aquaporin-9(AQP9) expression and brain edema around the hematoma in experimental intracerebral hemorrhage(ICH).Methods 128 SD rats were randomly divided into four groups: normal group,control group,ICH group and PDTC group.According to Rosenberg's methods,the models of experimental ICH were established.The rats in PDTC group were received PDTC intraperitoneally 2 h later.The brain weight column(BWC) at different time point was calculated by gray-wet method,and the expression of AQP9 was examined by immunohistochemistry.Results The BWC and expression of AQP9 in hematoma side of ICH begin to increase 4 h after ICH,peaked at 72 h,and decreased 120 h later.The BWC in opposite side of hematoma also increased 4 h after ICH and peaked at 72 h.Compared with control group,the BWC and expression of AQP9 in ICH group were higher,especially in hematoma side of brain(all(P

Objective To evaluate the efficacy and safety of repeated endoscopic sclerotherapy injection(ESI) and endoscopic variceal ligation(EVL) in eradication of esophageal varices among patients who survive an episode of first variceal hemorrhage with a high risk of rehaemorrhagia and death. Methods The correlated literatures were identified from Medline,Embsae,the Library Cochrance,PubMed and CNKI.RevMan 4.2 Software provided by the Library Cochrance was used for data analysis. Results A total of 4 randomized controlled trials were included.It was demonstrated that there was no significant difference in the esophageal varices eradication rate between repeated ESI and EVL(OR=0.75,95%CI: 0.48-1.15;P=0.19).However,the rehaemorrhagia rate of EVL after emergency hemostasis was significantly lower than that of ESI(OR=2.19,95%CI:1.44-3.31;P=0.000 2).Meanwhile,there was no significant difference in mortality between ESI and EVL(OR=1.34,95%CI:0.82-2.17;P=0.24).Little publication bias was found with funnel plot analysis. Conclusion EVL outperforms ESL in prevention of rehaemorrhagia in treatment of esophageal varices,while does no better than ESL in eradication of esophageal varices and mortality.

Background Epipolis laser in situ keratomihusis(Epi-LASIK) is an potential surgery for myopia because it synthesize advantages of LASEK and LASIK. But its clinical effectiveness and safeness is remarkable.Objective This study was to evaluate the clinical curative effects and safeness of Epi-LASIK for myopia in different diopter of population. Methods Retrospective study was designed for 208 eyes of 104 patients who underwent EpiLASIK for the correction of myopia. The patients were divided into two groups according to preoperative diopter:lower myopia group( ≤ -6.00 D, 111 eyes) and high myopia group ( ＞-6.00 D,97 eyes). The time of epithelial healing, postoperative syndrome, postoperative visual acuity, refraction, intraocular pressure (IOP) , the safe index, the efficacy index and haze were evaluated at 1,3,6,12 months postoperatively. The written informed consent was obtained from each individual before surgery. Results After operation, 20 eyes ( 18.02% ) of lower myopia group and 29 eyes (29.90%) of high myopia group had obvious pain, presenting statistically significant difference between two groups (X2 = 4. 060, P＜0.05 ). The mean time of epithelial healing was (5.49±0. 83 )days in lower myopia group and (5.85± 0.68 )days in high myopia group with a delayed epithelial healing time in high myopia group( u= 3. 377 ,P＜0.05 ).One year after the treatment,the uncorrected visual acuity( UCVA ) ≥ 1. 0 was 90. 99% ( 101 eyes) in lower myopia group and 75.26% ( 73 eyes) in high myopia group, and 9.91% ( 11 eyes) and 15.46% ( 16 eyes) of the eyes improved byl line or more in best spectacle corrected visual acuity(BCVA) ;whereas 3.60% (4 eyes)and 6. 18% (6 eyes)lost a line or more. 91.89% ( 102 eyes) and 85.57% (83 eyes) in both groups gained within 1.00 D of the attempted correction. The safety index and efficacy index were 1.04 and 0. 98 in lower myopia group,and 1. 01 and 0. 96 in high myopia group without statistically significant difference( P＞0. 05 ). haze occurred in 6 eyes in lower myopia group and 9 eyes in high myopia group and the difference in haze grading was not statistically significant between two groups ( P＞0. 05 ). The high intraocular pressure appeared in 10 eyes and 9 eyes in low myopia group and high myopia group respectively during the fellow up duration and back to normal after topical use of timolol. Conclusion Epi-LASIK is an effective and safe method for correction of different diopters of myopia because of its mild symptom and lower incidence of haze.

ve To compare the advantage and disadvantages of spectrophotometry assay, microwave di-gestion and standard circumfluence method for determination of chemical oxygen demand (COD) in various water samples. Methods The levels of COD of the water samples were determined by spectro-photometry, microwave di-gestion and standard circumfluence method respectively. Results The relative standard variations were 4.3% ~ 9.59% for spectrophotometry, 3.58% ~5.61% for microwave digestion method and 4.03% ~ 4.27% for standard circumfluence method. The recovery rates of adding standard material were 90% -95% , 90% ~96% and 90% ~98% respectively. Conclusion The microwave digestion method showed easy, rapid and accurate. It presented good practical prospect in monitoring environmental samples.

Based on M9 culture medium,the concentration of ingredients of culture medium was optimized for the fermentation of pNSR32/BL21(DE3),the engineering bacterial with spider silk protein,and lactose as an inducer.The condition of optimum culture medium was obtained for the expression of the high molecular weight recombinant spider silk protein by using orthogonal and individual factor experimental design.The result was showed that the optimum culture medium was consisted of 0.3% glycerol,3% yeast,0.75% tryptone,0.05%(NH_4)_2SO_4 and a little inorganic salt_.It was confirmed that the optimum culture medium will benefit the growth of bacterial and expression of recombinant spider silk protein.The production level of propose protein will attain at 20% of the total proteins in the fermentation.

Objective:To investigate the potential of differentiating into myocytes of the granulocyte colony stimulating factor(G CSF) and Simvastatin mobilized bone marrow stem cells. Methods:After injection of isoprenaline(ISO) interaperitoneally to develop acute ischemic model, rat bone marrow stem cells were mobilized by G CSF and dextran sulfate sodium salt and migrated to the site of myocardial infarction. Hearts were harvested from 24 hours to 24 weeks after administration of ISO for histopathological examination.Immunohistochemisty?HE and VG stain were used to detect infiltration of CD34 + monocytes and the regeneration of myocytes and the inhibition of fibroatrophy of ischemic myocardium.Results:24 hours after administration of ISO,a large amount of infiltrative monocytes and regenerative myocytes which were CD34 positive expression could be found in the infarct zones of the G CSF treatment group,while majority of the infiltrative inflammatory cells in control group were neutrophils and there was no infiltrative cells and myocytes which were CD34 positive expression,4 weeks after administration of ISO,there were a plenty of scar in control group,but not in the treatment group.Conclusion:Rat bone marrow stem cells were mobilized by G CSF and Simvastatin,and migrated to the site of myocardial infarction,and differentiated into viable cardiomyocytes or vascular endothelial.The heart function remarkably was improved by regeneration of myocytes,inhibition of fibroatrophy and protection of ischemic myocardial structure.
