Commercial production of bioethanol from lignocellulosic hydrolysates requires efficient fermenting strains. The abilities of the strain to converting all types of sugars in the hydrolysate to ethanol in high yield and to effectively tolerating/metabolizing inhibitors are necessary. Genome shuffling is a novel method for breeding, and it has been applied in pharmaceutical and food industry. This review summarized the technique of genome shuffling including principle, process, applications and its prospect for strains improvement in ethanol production from lignocellulosic hydrolysates.

This study was aimed to investigate the effects of extract from Tibetan medicine Berberis Cortex (TMBC) on expressions of protein kinase C (PKC-β), vascular endothelial growth factor (VEGF) and hypoxia-inducible factor (HIF-1α) in the retina of diabetic rats. Diabetic rats were established by one time intraperitoneal injection of strepto-zocin (STZ). Rats were randomly divided into the model group, low-dose TMBC group, medium-dose TMBC group, high-dose TMBC group, metformin group, calcium dobesilate group, berberine group and the normal control group. Intragastric administration was given. The medication amounts of TMBC in the low-dose, medium-dose and high-dose group were 5, 10, and 20 times to the adult medication dose. In the metformin group and the berberine group, 10 times of the adult medication dose were given. Distilled water was given in the model group and the normal con-trol group. After 6-week intragastric administration, all experimental rats were sacrificed. The expressions of PKC-β, VEGF and HIF-1α were examined by real-time fluorescence quantitative PCR assay and western blot. HIF-1α ex-pression was detected by immunohistochemistry. The results showed that compared with the normal control group, the mRNA and protein expression of PKC-β, VEGF and HIF-1α increased obviously in the retina of diabetic rats ( P<0.01). Compared with the model group, the mRNA expression of PKC-β, VEGF and HIF-1α in the high-dose and medium-dose TMBC group reduced obviously (P< 0.01). The protein expression levels of PKC-β, VEGF and HIF-1α were also obviously reduced (P< 0.05). The expressions of PKC-β, VEGF and HIF-1α in the low-dose TMBC group were obviously reduced (P < 0.05). It was concluded that TMBC can depress the expressions of HIF-1α, PKC-β and VEGF in the retina of diabetic rats, which can be served as a protective effect to prevent progress of di-abetic retinopathy.

Enterovirus 71 (EV71) is a member of the Entero-virus genus of the Picornaviridae family and is the major cause of Hand,foot,and mouth disease (HFMD) in children.Different strains from Gansu were cloned and the P1 protein was sequenced and analysed.Results indicate that there are three kinds of EV71 infections prevalent in Gansu.The VP1 protein from one of these strains,55F,was expressed.The recombinant protein was expressed with high level and reacted specifically with the EV71 patient antibody,the recombinant protein was also applied to raise antiserum in rabbits and after the fourth injection a high titer of antiserum was detected by ELISA assay.These data are useful for further clarification of prevalent EV71 strains in the north of China at the molecular level and provide a basis for EV71 diagnosis.

OBJECTIVETo investigate the impact of 1, 25-(OH)2D3 on left ventricular hypertrophy (LVH) in type 2 diabetic rats.

METHODSType 2 diabetic mellitus (DM) model rats were established by intraperitoneally injecting with 30 mg/kg streptozotocin. After 8 weeks, 19 male rats were identified as diabetic with left ventricular hypertrophy (LVH) by ultrasound examination, and randomly assigned into three groups: untreated (DM-LVH, n=7), treated with insulin (DM-LVH+INS, n=6), and treated with 1, 25-(OH)2D3 (DM-LVH+VD, n=6). Healthy male rats were used as the controls group (n=6). The fasting blood glucose and the insulin level were determined weekly. The left ventricular mass index, myocardial collagen content, collagen volume fraction, and 1, 25-(OH)2D3-receptor level were determined by 4 weeks later.

RESULTSIn the DM-LVH model group, the insulin level was significantly decreased compared with the non-diabetic control group (P<0.05), whereas the blood glucose, left ventricular mass index, myocardial collagen content, collagen volume fraction, and 1, 25-(OH)2D3-receptor expression were significantly increased (all P<0.05). In the DM-LVH+INS and DM-LVH+VD groups, the insulin levels were significantly increased compared with the DM-LVH model group (P<0.05), whereas the other parameters were significantly decreased (all P<0.05).

CONCLUSION1, 25-(OH)2D3 could reverse LVH in diabetic rats and that the mechanism may involve stimulating insulin secretion and reducing blood glucose via direct up-regulation of 1, 25-(OH)2D3-receptor expression.

ObjectiveTo investigate effects of pamidronate on the proliferation and differentiation of osteoblasts of rats in vitro.MethodsOsteoblasts isolated from newborn rat calvaria were treated with various concentrations of pamidronate, the proliferation of osteoblasts was evaluated with the method of methyl thiazole tetrazolium (MTT) and activity of alkaline phosphatase (ALP) in medium was measured with kit of ALP detecting.ResultsThe proliferation of osteoblasts increased under the stimulation of Pamidronate range 10-6-M-10-12 M(P<0.05), but was inhibited at the concentration of high level (10-4 M). The activity of ALP decreased in the experiment.ConclusionPamidronate can act on the osteoblasts directly and increase the proliferation of bone cells, but inhibit the differentiation of the same cells.

Objective To study the effect of local mild hypothermia on the expression of matrix metallopro- teinases-2/9 (MMP-2/9) and brain edema in experimental intracerebral hemorrhage (ICH) in rat. Methods One hundred and forty-five Wistar rats were randomly divided into a normothermia sham-operation (NSO) group ( n = 15 ), a normothermia intracerebral hemorrhage (NICH) group (n = 75 ) and a mild hypotbermia intracerebral hemor- rhage (MHICH) group (n = 75). Autologous arterial blood was stereotaxically injected into the right caudate nucleus of the rats of the NICH and MHICH groups to make intracerebral hemorrhage model. The rats in the MHICH group were then subjected to 4 hours of local mild hypothermia, while those in the NICH group were under the room temper- ature. The brain water content, permeability of brain-blood barrier (BBB) and expressions of MMP-2/9 were meas- ured by immunohistochemistry method at 6 h, 24 h, 72 h, 5 d and 7 d after operation. Results In NICH group, the brain water content, permeability of BBB and expression of MMP-9 all began to increase at 6 h and peaked at 3 d after injection of blood and still higher than the NSO group at 7 d. The expression of MMP-2 only began to increase little at 24 h and peaked at 5 d after operation and remained highly expressed at 7 d. In the MHICH group, the chan- ges of brain water content, permeability of BBB and expression of MMP-9 were similar to those of the NICH group, but the extent of changes was significantly lower at the every time point. In NICH group and MHICH group, MMP-9 expression was positively correlated with both the brain water content and the permeability of BBB, but MMP-2 ex- pression was not correlated with them. Conclusion Mild hypothermia might protect BBB against injury caused by ICH and relieve brain edema and inflammation reaction through inhibiting the expression of MMP-2/9.
