Abstract: AIM: To investigate optimal timing for therapeutic efficacy of entecavir for acute-on-chronic hepatitis B liver failure (ACLF-HBV) in hepatitis B e antigen (HBeAg)-negative patients. METHODS: A total of 109 inpatients with ACLF-HBV were recruited from the Department of Infectious Diseases of the Third Affiliated Hospital, Sun Yat-sen University from October 2007 to October 2010. Entecavir 0.5 mg/d was added to each patient’s comprehensive therapeutic regimen. Patients were divided into three groups according to model for end-stage liver disease (MELD) score: high (≥ 30, 20 males and 4 females, mean age 47.8 ± 13.5 years); intermediate (22-30, 49 males and 5 females, 45.9 ± 12.4 years); and low (≤ 22, 28 males and 3 females, 43.4 ± 9.4 years). Statistical analysis were performed using SPSS 11.0 software. Data with normal distribution were expressed as mean ± SD and comparisons were made with Student’s t tests. A value of P < 0.05 was considered statistically significant. Viral loads were related exponentially and logarithmic data were used for analysis. RESULTS: For 24 patients with MELD score ≥ 30, treatment lasted 17.2 ± 16.5 d. Scores before and after treatment were significantly different (35.97 ± 4.87 and 40.48 ± 8.17, respectively, t = -2.762, P = 0.011); HBV DNA load was reduced (4.882 ± 1.847 copies log10/mL to 3.685 ± 1.436 copies log10/mL); and mortality rate was 95.83% (23/24). Of 54 patients with scores of 22-30, treatment lasted for 54.0 ± 43.2 d; scores before and after treatment were 25.87 ± 2.33 and 25.82 ± 13.92, respectively (t = -0.030, P = 0.976); HBV DNA load decreased from 6.308 ± 1.607 to 3.473 ± 2.097 copies log10/mL; and mortality was 51.85% (28/54). Of 31 patients with scores ≤ 22, treatment lasted for 66.1 ± 41.9 d; scores before and after treatment were 18.88 ± 2.44 and 12.39 ± 7.80, respectively, (t = 4.860, P = 0.000); HBV DNA load decreased from 5.841 ± 1.734 to 2.657 ± 1.154 copies log10/mL; and mortality was 3.23% (1/31). CONCLUSION: For HBeAg-negative patients with ACLF-HBV, when entecavir was added to comprehensive therapy, a MELD score ≥ 30 predicted very poor prognosis due to fatal liver failure.

Abstract: Using the Keldysh nonequilibrium Green function and equation-of-motion technique, we investigate the spin-dependent transport through a closed Aharonov-Bohm interferometer coupled to ferromagnetic leads. With the Fano factor, We analyse the effect of the Fano and the Kondo resonance on the conductance and the variation of the conductance with the spin-polarization strength and the magnetic flux in both the parallel and the antiparallel lead-polarization alignments. Our results show that the conductance can be controlled effectively by the spin-polarization strength and the magnetic flux, while the line shapes of the conductance depend mainly on the magnetic flux and that a large tunneling magnetoresistance and a negative tunneling magnetoresistance can arise by adjusting the relative parameters. This system is a possible candidate for spin valve transistors and is of potential applications in the spintronics.

Abstract: 为探讨枇杷Eriobotrya japonica (Thunb.) Lindl.]对高温胁迫的响应,对‘红种’枇杷果皮热伤害的抗氧化特性进行研究。结果表明,在自然光下,枇杷果皮热伤害的阈值为40℃ (1.5 h),且果皮热伤害与温度和持续时间关系密切,光照可促进热伤害的发生。枇杷果皮受热伤害程度与果实本身的营养状态有关,果肉维生素C (Vc)、钙(Ca)含量越低, 果皮热伤害级数越高。与25℃相比,40℃高温处理增加了果皮的超氧阴离子和丙二醛(MDA)含量,而超氧化物歧化酶(SOD)、过氧化物酶(POD)的活性呈下降趋势。这揭示了高温胁迫下枇杷果皮对热伤害的抗氧化响应机制。

Abstract: Chinese herb medicine (CHM) is the most commonly reported traditional Chinese medicine (TCM) modality. This study aimed to assess the prevalence and associated factors of CHM use in cancer patients in southwestern China. Cancer patients from eleven comprehensive cancer centers were asked to complete a structured questionnaire. Of 587 available replies, 53.0% used CHM. Multiple logistic regression analysis showed that educational level, stage of disease, duration of cancer since diagnosis, marital status, and previous use of CHM were strongly associated with CHM use after cancer diagnosis. The source of information about CHM was mainly from media and friends/family. CHM products were used without any consultation with a TCM practitioner by 67.5% of users. The majority used CHM to improve their physical and emotional well-beings and to reduce cancer therapy-induced toxicities. About 4.5% patients reported side effects of CHM. This survey revealed a high prevalence of CHM use among cancer patients. However, these patients did not get sufficient consultation about the indications and contradictions of these drugs. It is imperative for oncologists to communicate with their cancer patients about the usage of CHM so as to avoid the potential side effects.

Abstract: Dynamics of zonal flow excitation in tokamak plasmas is investigated based on the resistive interchange mode turbulence. Employing low freedom approach, the resistive interchange mode turbulence zonal flow system is solved both analytically and numerically. Our results show that the large scale zonal flow or oscillating zonal flow can be excited in the case of sufficiently high pressure gradient (driving force).
