| 1 | Heavy metal concentrations in edible bivalves and gastropods available in major markets of the Pearl River Delta显示文摘Molluscs are able to accumulate heavy metals and impose health hazard to consumers. The main objective of the present study is to investigate the heavy metal concentrations in edible bivalves and gastropods available in major markets of the Pearl River Delta. Fourteen species of edible molluscs were purchased from six markets in Hong Kong and Guangdong Province. The fresh of these biota were tested for their cadmium (Cd), copper (Cu), zinc (Zn), lead (Pb), nickel (Ni), chromium (Cr), antimony (Sb) and tin (Sn) concentrations (based on wet weight). The results indicated that amongst the 14 edible molluscs, only Cd, Pb, Ni, Cr, Sb and Sn concentrations in three species ( Ruditapes philippinarum, Perna viridis and Hemifusus tuba ) were within the local regulatory limits. Over 60% of bivalve species exceeded maximum permitted levels of Cd (2 μg/g) and Cr (1 μg/g), while over 40% of gastropod species exceeded the maximum levels of Sb (1 μg/g) and Cr (1 μg/g). Most of the samples collected from Hong Kong had significantly higher contents of Pb and Sb, but similar levels of Cd, Cu and Zn when compared with samples collected across the border ( p <0 05; p <0 01; p <0 001 respectively). In general, the molluscs purchased in Guangdong markets had higher metal contents than those purchased from the Hong Kong markets. When compared with the Provisional Tolerable Weekly Intake or Maximum Acceptable Daily Load recommended by FAO/WHO Expert Committee on Food Additives, Cd levels of five species ( Anadara ferruginea, Pinna pectinata, Chlamys nobilis, Babylonia lutosa and Hemifusus terntanus ) and Cr levels of seven species ( Anadara ferruginea, Paphia undulata, Pinna pectinata, Babylonia lutosa, Hemifusus terntanus, Cymbium melo and Cipangopaludina chinensis ) were higher than both the human daily acceptable limits (for Cd and Cr respectively) and the local regulatory levels (for Cd and Cr respectively). | FANG Zhan-qiang CHEUNG R.Y.H.

| 3 | Analysis of genetic relationship in mutant silkworm strains of Bom-byx mori using inter simple sequence repeat (ISSR) markers显示文摘Amplified inter simple sequence repeats (ISSR) markers were used to determine genetic relationships among mutant silkworm strains of Bombyx mori. Fifteen ISSR primers containing simple sequence repeat (SSR) motifs were used in this study. A total of 113 markers were produced among 20 mutant strains, of which 73.45% were found to be polymorphic. In selected mutant genetic stocks, the average number of observed allele was (1.7080 ± 0.4567), effective alleles (1.5194 ± 0.3950) and genetic diversity (Ht) (0.2901 ± 0.0415). The dendrogram produced using the unweighted pair group method with arithmetic means (UPGMA) and cluster analysis made using Nei’s genetic distance resulted in the formation of one major group containing 6 groups separated 20 mutant silkworm strains. Therefore, ISSR amplification is a valuable method for determining the genetic variability among mutant silkworm strains. This efficient molecular marker would be useful for characterizing a considerable number of silkworm strains maintained at the germplasm center. | Dhanikachalam Velu Kangayam M.

| 8 | REAL-TIME FLOOD FORECASTING MODELING OF 1D UNSTEADY CHANNEL FLOW AND KALMAN FILTER显示文摘WT5”BZ]The model of 1D unsteady channel flow combined with the Kalman filter for real-time channel flood forecasting was attempted in this study. The suitable upstream and downstream boundary conditions were suggested. The system equation was given by the linearization of the finite-difference equations of the mass conservation and momentum equations as well as the boundary conditions. In the Kalman filter updating model, because the number of measurement variable is less then that of state-space variables, the measurement error covariance matrix could be estimated in real time through the innovation sequence, and the system error covariance matrix needs to be estimated preliminarily. A real example of flood forecasting in the Huaihe River was given to explain how the method works. The results show that the model is reasonable and effective. [WT5”HZ] | Li, Z.J.

| 11 | 批评理论的趋向显示文摘博斯韦尔:“先生,那什么是诗呢?”约翰逊:“哎,先生,说它不是什么,倒容易得多。我们都知道光线是啥,可要说出来它究竟是什么,就不那么容易了。”这是一位受过教育的人为尽可能精确地在各类事物中探寻本质所说的一番话。——亚里士多德《尼各马可伦理学》不是就艺术与外界自然的关系、艺术与观赏者的关系或者艺术与艺术品本身内部需要的关系,而是就艺术与艺术家之间的关系来提出和回答美学上的问题,是直至几十年以前现代批评趋势的特征,并且继续成为当今许多(也许是大多数)批评家的倾向。要反叛具有二千五百年历史的西方艺术理论,这种观点显得非常稚嫩。因为众多批评家所持有的这种观点,作为一种广泛的艺术研究方法。 | M.H.艾布拉姆斯 罗务恒 | 1986 | 文艺理论研究1986，，6： | 4 |
| 12 | N末端脑利钠肽(NT-proBNP)对硬皮病相关性肺动脉高压的作用显示文摘Aims: The aims of this study were to evaluate the diagnostic value and to explore the prognostic value of N-terminal brain natriuretic peptide(N-TproBNP) in patients with systemic sclerosis(SSc) both with and without pulmonary arterial hypertension(PAH). Methods and results: N-TproBNP, six minute walk distance(SMWD), haemodynamics(at right heart catheterization) or tricuspid gradient(by echocardiography), and survival were assessed in 109 patients with SSc. The study population included 68 individuals with PAH[mean pulmonary artery pressure(PAP) >25 mmHg and pulmonary capillary wedge pressure< 15 mmHg] and 41 individuals without PAH. In patients with PAH, the prognostic value of baseline and change in WHO functional class, N-TproBNP levels, and SMWD were compared using Kaplan-Meier survival curves and Cox proportional hazard analysis. The mean duration of follow-up was 10 months(range 1-18 months). One year survival in patients with normal PAP was 100%when compared with 83.5%in those with SSc-PAH(P< 0.05). The patients without PAH had a mean N-TproBNP level of 139 pg/mL(SD 151); those with SSc-PAH had a significantly higher mean NTproBNP level of 1474 pg/mL(SD 2642)(P=0.0002). Among patients with PAH for every order of magnitude increase in N-TproBNP level there was a four-fold increased risk of death(P=0.002 for baseline level and P=0.006 for follow-up level). Baseline N-TproBNP levels were correlated positively with mean PAP(r=0.62; P< 0.0001), pulmonary vascular resistance(PVR)(r=0.81; P< 0.0001), and inversely with SMWD(r=-0.46; P< 0.0001). Among patients with SSc-PAH, 13 patients(19%) were in WHO functional classes Ⅱ and had mean NTproBNP levels of 325 pg/mL(SD 388). Fifty-three patients(78%) were in WHO classes Ⅲ and IV and had significantly higher mean N-TproBNP levels of 1677 pg/mL(SD 2835)-(P=0.02). At an N-TproBNP level of 395 pg/mL, the sensitivity and specificity for predicting the presence of SSc-PAH were 56 and 95%respectively. Conclusion: Raised N-TproBNP levels are directly related to the severity of PAH. In screening programs, SSc patients with an N-TproBNP in excess of 395 pg/mL have a very high probability of having pulmonary hypertension. Baseline and serial changes in N-TproBNP levels are highly predictive of survival. A 10-fold increase in N-TproBNP level on therapy is associated with a greater than three-fold increase in mortality, and may indicate therapeutic failure. | Williams M.H. Handler C.E. Akram R. J.G.

| 14 | Effect of Matricaria chamomilla Hydroalcoholic Extract on Cisplatin-induced Neuropathy in Mice显示文摘AIM: Cisplatin-based chemotherapy is a mainstay for the treatment of solid tumors, especially colorectal, ovarian, testicular, bladder, and lung cancer. Studies have shown that cisplatin could have painful effects on human and animal models. Matri-caria chamomilla (MC) has analgesic and anti-inflammatory effects. The aim of this study was to investigate the effects of MC hydro-alcoholic extract on cisplatin-induced peripheral neuropathy and to compare with morphine in mice. METHODS: Experiments were performed on 60 NMRI male mice weighed 25 g to 30 g which have been divided into 6 groups. The first group received normal saline; the second group received MC hydroalcoholic extract; the third group received cisplatin; the fourth group received MC hydroalcoholic extract and cisplatin, 96 hours before formalin test; the fifth group received morphine and the sixth group received cisplatin and mor-phine. The time of injected hind paw biting and licking time were measured in 5-minute interval for an hour. RESULTS: Results showed that formalin induced significant (P < 0.05) pain response (the first phase: 0-5 min and the second phase: 15-40 min after injection). Administration of MC extract before formalin injection showed significant (P < 0.05) decrease of pain responses in the first and second phase. Administration of cisplatin produced significant (P < 0.05) increase in pain response in both phases of formalin test. Injection of MC extract and cisplatin together have shown that MC is able to decrease the second phase of cisplatin-induced pain sig-nificantly (P < 0.05). Morphine decreased cisplatin-induced pain in the first and second phase of formalin test significantly ( P < 0.05). In comparison morphine has analgesic effects in the first phase and MC extract has anti inflammatory effects in the second phase of formalin test significantly (P < 0.05). CONCLUSION: MC and cisplatin have analgesic and painful neuropathic respective effects, and MC hydroalcoholic extract is able to decrease cisplatin-induced pain and inflammation better than morphine. | A.

| 16 | An empirical study on vortex-generator insert fitted in tubular heat exchangers with dilute Cu–water nanofluid flow显示文摘The heat transfer enhancement(HTE) in tubular heat exchangers fitted with vortex-generator(VG) inserts is experimentally investigated. The studied four parameters and ranges are: winglets-pitch ratio(1.33, 2.67, and 4),winglets-length ratio(0.33, 0.67, and 1), winglets-width ratio(0.2, 0.4, and 0.6), and Reynolds number(5200to 12200). The testing fluids are the water and Cu–water nanofluid at the volumetric fraction of 0.2%. The results obtained on HTE, pressure drop, and performance evaluation criterion(PEC) are compared with those for water in a smooth tube. It is found that the VG inserts with lower winglets-pitch ratio and higher winglets-length/width ratios present higher values of HTE and pressure drop. Over the range studied, the maximum PEC of 1.83 is detected with the Cu–water nanofluid inside the tube equipped with a VG insert at the winglets-width ratio of0.6 for the maximum Reynolds number, when the heat transfer rate and pressure drop are 1.24 times and 2.03 times of those in the smooth tube. Generalized regression equations of the Nusselt number, friction factor, and PEC are presented for the tubular heat exchangers with the VG inserts for both water and Cu–water nanofluid.It is concluded that the main advantage of the VG inserts is their simple fabrication and considerable performance, particularly at higher Reynolds number. | M.
