Objective To investigate the relationship between the acute phase blood glucose and the severity and prognosis of stroke in patients with stroke. Methods One hundred seventy-three consecutive patients with acute stroke were randomly allocated into either a hyperglycemia group (n =72) or a normal group (n = 101) according to whether their random blood glucose levels were > 7.8 mmol/L or not. The average time from stroke onset to admis-sion was 6.5 ± 5.1 hours. The patients were evaluated by the National Institutes of Health Stroke Scale (NIHSS) and Glasgow Coma Stroke (GCS) scores within 20 minutes after clinical reception, The plasma blood glucose detection and bead CT scan were completed in 40 minutes.The patients with cerebral infarction were classified according to the Oxfordshire Community Stroke Project (OCSP) criteria, and the survivors were evaluated by the modified Rankin scale (mRS) after 3 months. Results There were no significant differences between the two groups in age, gender, vascular risk factors, stroke property and treatment principle. There were significant differences between the NIHSS and GCS at the first admission and the mRS scores at 3 months (P<0.01). The proportion of the patients with the history of diabetic mellitus in the random hyperglycemia group was significantly higher than that in the normal group (P<0.01).The random blood glucose levels were not correlated with the severity of stroke between the 2 groups of patients with the history of diabetes mellitus; the increased random blood glucose levels were significantly correlated with the severity and prognosis of stroke between the 2 groups of patients without the history of diabetes mellitus (P<0.01). Conclusions The increased blood glucose in patients with stroke without the history of diabetes mellitus in acute phase is an independent risk factor for the severity and prognosis. The increased random blood glucose in patients with stroke in acute phase may also suggest having the history of diabetes mellitus.

Human Immunodeficiency Virus Type 1 exists in vivo as quasispecies, and one of the genome's characteristics is its diversity. During the antiretroviral therapy, drug resistance is the main obstacle to effective viral prevention. Understanding the molecular evolution process is fundamental to analyze the mechanism of drug resistance and develop a strategy to minimize resistance. Objective: The molecular evolution of drug resistance of one patient who had received reverse transcriptase inhibitors for a long time and had treatment which replaced Nevirapine with Indinavir was analyzed, with the aim of observing the drug resistance evolution pathway. Methods: The patient, XLF, was followed-up for six successive times. The viral populations were amplified and sequenced by single-genome amplification. All the sequences were submitted to the Stanford HIV Drug Resistance Database for the analysis of genotypic drug resistance. Results: 149 entire protease and 171 entire reverse transcriptase sequences were obtained from these samples, and all sequences were identified as subtype B. Before the patient received Indinavir, the viral population only had some polymorphisms in the protease sequences. After the patient began Indinavir treatment, the variants carrying polymorphisms declined while variants carrying the secondary mutation G73S gained the advantage. As therapy was prolonged, G73S was combined with M46I/L90M to form a resistance pattern M46I/G73S/L90M, which then became the dominant population. 97.9% of variants had the M46I/G73S/L90M pattern at XLF6. During the emergence of protease inhibitors resistance, reverse transcriptase inhibitors resistance maintained high levels. Conclusion: Indinavir- resistance evolution was observed by single-genome amplification. During the course of changing the regimen to incorporate Indinavir, the G73S mutation occurred and was combined with M46I/L90M.

Objective To investigate the effects and mechanisms of sorafenib on hepatic stellate cell viability and activation in the microenvironment of liver tumor.Methods The effects of LX2 cells on HepG2 cell proliferation were observed by coculture of LX2 and HepG2 cells.MTT assay was used to observe the effects of sorafenib on LX2 proliferation,and expression of α-smooth muscle actin (α-SMA) was measured immunocytochemically in LX2 cells treated with different concentrations of sorafenib.Changes in PDGF-BB and TGF-β1 concentrations were detected in LX2 supernatant using ELISA.Expression of ERK1,ERK2,and AKT signaling pathways were measured using Western blot.Furthermore,LX2 cells were cocultured with HepG2 cells for 24 hours to observe their effects on the invasive ability of HepG2 cells.Result After coculture of LX2 and HepG2 cells,HepG2 cells increased in the experimental group more than those of in the control group.After treatment with various concentrations of sorafenib for 12,24,36 or 48 hours,the viability of treated LX2 cells was lower than the controls in a concentration-and time-dependent manner.As sorafenib concentration and time of exposure increased,α-SMA expression became weaker in treated cells.PDGF-BB and TGF-β1 concentrations decreased with higher sorafenib concentrations and with longer exposure under the same concentration.ERK1,ERK2 and Akt expression was identical between treated and control groups,but their phosphorylated expression decreased with increased concentrations of sorafenib.The invasive ability of HepG2 cells induced by LX2 gradually decreased as sorafenib concentrations increased.Conclusions Sorafenib suppressed α-SMA expression,inhibited PDGF-dependent signaling pathways in HSCs,downregulated PDGF-BB and TGF β1 expression in the supernatant of HSCs,and restrained the viability and activation of HSCs.Sorafenib treatment therefore resulted in suppressed proliferation and invasion of HepG2 cells.

Results In 24 h, the content of MMP-13 mRNA in fluoride group(0.830±0.043), aluminum group(1.279±0.060) and fluoride plus aluminum group(0.983±0.028) was higher than that in the control group(0.707±0.026, P<0.05), and relative expression of MMP-13 mRNA in aluminum group was the highest. In 48 h, the content of MMP-13 mRNA in fluoride group (0.964±0.180), aluminum group (1.333±0.105) and fluoride plus aluminum group (0.915±0.137) was higher than that in the control group(0.660±0.055, P<0.05), and the relative expression in aluminum group was the highest. In 72 h, the content of MMP-13 mRNA in fluoride group(0.866±0.115), aluminum group(0.846±0.089) and fluoride plus aluminum group(0.967±0.196) had no statistical significance(P>0.05) compared with the control group(0.809±0.179). In 24 h, the content of MMP-13 protein in fluoride group(1.050±0.084), aluminum group(1.010±0.113) and fluoride plus aluminum group(0.977±0.202) had no statistical significance(P>0.05) compared with the control group(0.860±0.038). In 48 h, the content of MMP-13 protein in fluoride group(0.671±0.020), aluminum group(1.134±0.094) and fluoride plus aluminum group (0.923±0.087) was higher than that in the control group (0.647±0.025, P<0.05), but no significant difference being observed between groups (P>0.05). In 72 h, the content of MMP-13 protein in fluoride group(0.672±0.022), aluminum group(1.088±0.072) and fluoride plus aluminum group(0.772±0.030) was higher than that in the control group(0.577±0.026, P<0.05). It was the highest in the aluminum group, the intra-group difference had statistical significance(P<0.05). Conclusions Fluoride and aluminum damage chondrocytes to some extent, toxicity of aluminum itself is greater than fluoride and fluoride plus aluminum. Abnormal expression of MMP-13 can be observed in the chondrocyte damage process induced by fluoride and aluminum.
