In industrial glutamate fermentation, intermitted feeding glucose with the help of off-line glucose measurement is generally necessary. This kind of feeding strategy could cause large variations in glucose concentration so that it is not favorable for the achievement of efficient and stable glutamate fermentation. Glutamate fermentation is characterized with typical non-growth association behavior, and during glutamate production phase glucose consumption is closely correlated with ammonia consumption. In this study, glucose concentration was controlled at various pre-determined levels by predicting glucose consumption amount and thus its concentration with the aid of on-line monitoring ammonia consumption. When glucose concentration was controlled around a lower level of 5 g/L~10 g/L, the final glutamate concentration could reach a relatively higher level of 80 g/L. In this way, the huge osmotic stress change due to the large glucose concentration variation with the intermitted feeding method could be avoided and the glutamate fermentation performance enhancement be expected.

? AlM: To estimate the clinical significance of the microculture of humor and vitreous and vancomycin intraocular injection in treatment of suppurative endophthalmitis associated with intraocular foreign bodies.
?METHODS: Totally 65 patients with penetrating eye trauma and retained intraocular foreign bodies in emergency operation and intraocular injection from January 2012 to September 2014 were regarded as the study group, another 62 patients with penetrating eye trauma and retained intraocular foreign bodies in emergency operation without intraocular injection before August 2011 were regarded as the control group. Aqueous humor and vitreous humor were taken from each patient of the study group and the control group for bacteria and fungus cultivation. The study group was treated with 1mg vancomycin intraocular injection after operation, while the control group was not.
?RESULTS: The incidence of endophthalmitis in the control group was 16% ( 10 cases ) , while in the study group was 3% ( 2 cases ) , with significant difference between two groups (x2 =6. 32, P<0. 05). The aqueous humor germiculture in both groups was in low positive rates, the study group was 3% (2 cases) and the control group was 2% (1 case), with no difference between two groups (P>0. 05). The positive rate of vitreous humor germiculture in study group was 14% (9 cases), and the incidence of endophthalmitis was 3%. The positive rate of vitreous humor germiculture in control group was 11% (7 cases) and the incidence of endophthalmitis was 16%, with significant differences between two groups (P<0. 05).?CONCLUSlON: lntraocular foreign bodies treated with emergency operation and vancomycin intraocular injections can decrease the incidence of suppurative endophthalmitis and have a good vision prognosis for the second stage of operation.

Objective To develop an easy,rapid and reproducible cefotaxime-agar medium(CTX- AM)for phenotypic detection of extended-spectrum ?-lactamases(ESBLs)and AmpC ?-lactamases (AmpCs)in Enterobacteriaceae.Methods The surface of a cefotaxime(CTX,0.5 ?g/ml)-Mueller- Hinton agar and ceftizoxime(CAZ,1 ?g/ml)-Mueller-Hinton agar plate was inoculated with a lawn of E. coli ATCC 25922 according to the standard disk diffusion method,respectively.Immediately prior to use.blank and clavulanic acid(10 ?g),cloxacillin(300 ?g),clavulanic acid/cloxacillin(10/300 ?g) disk were rehydrated with 10 ?l of saline and several colonies of each test organism were applied to disks. Then the results of CTX-AM method to interpret based on a zone of growth around the periphery of disks.A total 58 of ESBL and AmpC producing and non-producing isolates of Enterobacteriaceae,as identified by the double-disk enhancement test(DDET)and the three-dimensional extract method(TDEM).were used to evaluate the CTX-AM method.Positive control(E.cloacae 029M,K.pneumoniae ATCC 700603)and negative control(E.coli ATCC 25922)strains were included.Results The results of CTX-AM method were similar to the DDET and TDEM method for detecting ESBLs and AmpC production in Enterobacteriaceae,respectively.But inhibitor-resistant ?-lactamase(IR-BLs)and other ?-lactamases were not detected by DDET method.Conclusions The new method described here allows for testing of ESBL and AmpCs on a single plate.It is easy to perform and interpret,and also cost-effective,clinical laboratories may use this technique routinely to detect the oresence of ESBL and AmoCs.

Objective To evaluate the effect of health education on controlling endemic fluorosis in Shaanxi Province between 2004 and 2006. Methods Hanbin, Pingli, Ziyang and Hanyin were selected for the investigation in 2004;in addition to the four areas, Zhengping, Shiquan and Langao were also for the investigation in 2006. Two schools were selected in each area, and 2 villages as the investigation spots. Fifty pupils in the fifth grade in each school, and 30 housewives between 25 - 50 years old in each village were chosen as the research subjects. Referring to the health education questionnaire in Technique Scheme of Endemic Disease Prevention Granted by Central Government of 2004, the degree of health education of endemic fluorine, arsenic poisoning in pupils and housewives were investigated. Results In 2004 and 2006, the average mark of pupils in school was 54.7 and 83.6, the pass rate was 57.5% (230/400) and 90.2% (629/697), respectively;the average mark of housewives was 59.7 and 83.9, the passing rate was 59.6% (143/240), 87.6%(338/386) respectively, indicating that the outcome was improved obviously in 2006 compared to that in 2004. Conclusions In the past three years, health knowledge of endemic arsenic and fluorosis has been improved among pupils and housewives in these areas.

Objective To explore the correlation between the incidence of abdominal and pelvic artery distortion and age using dig-ital three-dimensional reconstruction,in order to assess risk in uterine artery embolization surgical approach.Methods Collecting the CTA datasets of 475 patients,group A aged 11-27 (n=40),group B aged 28-44(n=218),group C aged 45-61(n=197), group D aged 62-78(n=20).The 3D model of pelvic arteries was reconstructed by mimics software,and the arterial distortion was recorded by rotating and observing the 3D model,which was further classified into three categories.One was the distortion of the aorta only,the second was the distortion of iliac artery,and the third being distortion of both sturctures.the number of cases appeared arterial distortion in every age group was calculated and the ratio of the total cases to each age group was counted.Results There were 128(26.9%)cases appeared arterial distortion,the last 347(73.1%)were not found distortion in any artery.Of the 128 cases,the occurrence rates of arterial distortion in each age group were 2.5%、11.9%、44.7%、65% for group A,B,C and D respec-tively.Pearson linear correlation analysis showed that the incidence of arterial distortion positively correlated with age (r=0.404,help of three-dimensional reconstruction.The occurrence rate of artery distortion is increased with age and the iliac artery distortion occurrence is higher than that of the aorta artery.
