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.

OBJECTIVEBased on the potential for nucleotide analogues to affect DNA polymerase-gamma, which controls the proliferation of mitochondria, this study aimed to determine whether long-term treatment with entecavir can cause damage to mitochondrial (mt)DNA in the peripheral blood mononuclear cells (PBMCs) of patients with chronic hepatitis B (CHB).

METHODSPatients with CHB were divided into three groups according to their history of treatment type and duration: (1) entecavir monotherapy for 2 years, n = 17; (2) entecavir monotherapy for 3 years, n = 17; (3) non-antiviral treatment as control, n = 18. PBMCs were isolated and used to assess the mtDNA content by quantitative real-time PCR of mitochondria-specific genes. Plasma malonaldehyde (MDA) and F2-isoprostanes were measured by enzyme linked immunosorbent assay. Plasma total antioxidant capacity (TAOC) was detected by spectrophotometry.

RESULTSThe relative quantity (RQ; of mtDNA to nuclear (n)DNA) was significantly lower in the 3-year treatment group (0.5+/-0.3) than in the control group (1.4+/-1.2; F = 5.233, P = 0.009). The RQ was also significantly lower in the 2-year treatment group (0.4+/-0.2) than in the control group (P = 0.004). The level of F2-isoprostanes (ng/mL) was significantly lower in the 3-year treatment group (1.2+/-0.5) than in the control group (3.6+/-2.9, P = 0.002) or the 2-year treatment group (2.4+/-1.3, P = 0.007). The TAOC was significantly different when compared among all three groups (F = 4.326, P = 0.019). The TAOC (IU/mL) in the 3-year treatment group (2.6+/-1.2) was significantly lower than in the control group (5.0+/-3.0 P = 0.005), but was not significantly different than that for the 2-year group (3.2+/-1.6, P = 0.227). The levels of MDA were not significantly different between any of the groups (F = 0.291, P = 0.749).

CONCLUSIONLong-term treatment with entecavir, up to 3 years, leads to decreased mtDNA content in PBMCs. Since no clinical manifestations of mtDNA toxicity were observed, the consequent damage to the mitochondrial function may be compensated for by yet unknown mechanisms.
