Objective To investigate the present situation of water benzo (a) pyrene contamination in China and to make an ecological risk assessment. Methods B(a)P, one of the 16 prior-controlled polycyclic aromatic hydrocarbons pollutants selected by US EPA, is used to reflect the potential risk of PAHs, a strong carcinogen. Since the content of B(a)P in water is rather low, the contamination levels in the sediment of domestic water environment are assessed with two ecological assessment standards: risk assessment guidelines of chemical concentrations in marine and estuary sediments and sediment quality guidelines for the protection of aquatic life and probable effects levels for adverse biological effects. Results The contents of B(a)P were 0.06-707.12 ng/g in sediment of rivers and lakes, 7.1-1 492.12 ng/g in surface sediment of seaports, marines, and tidal flats respectively. Conclusion Domestic water environment is generally suffered from B(a)P contamination, but still under the adverse effect level.

Objective To explore the association between psychiatric disorders and socioeconomic status such as education,income,employment and area of community settings in Zhejiang province.Methods Data were from the epidemiological survey of mental illnesses aged 15 and older in 2001(n=14 632).Psychiatric disorders were measured by GHQ-12 with a cut-point 4.Logistic multilevel analysis was the main statistical method being used.Results The overall prevalence of psychiatric disorders was 18.5%(95% confidence intervals,17.9% to 19.1%),higher than the data from Hebei province(u=4.39,P＜0.001).Annual household income and employment were strongly associated with psychiatric disorders especially for those with low income(odds ratio 3.45,95%CI:1.72-6.67)and unemployment(odds ratio 2.03,95%CI:1.73-2.40).Factors as regional effect and education level showed weak or inconsistent association with psychiatric disorders after controlling on other indicators.Conclusion Inverse gradient relation between psychiatric disorders and SES seemed as the main result of low SES individual characteristics and some minor effects at the county level.

This study is to establish physiologically based pharmacokinetic (PBPK) models of famitinib in rat and monkey, and then to predict the pharmacokinetics and tissue distribution of famitinib in human based on the PBPK models. According to published paper, previous studies and the chemical properties of famitinib predicted by ACD/ADME suite and SimCYP, the PBPK models of rat and monkey were established and optimized using GastroPlus. And then, the PBPK models were applied to predict the pharmacokinetic and tissue distribution of famitinib in human. The results showed that the PBPK models of rat and monkey can fit the observed data well, and the AUC0-∞, ratios of observed and calculated data in rat and monkey were 1.00 and 0.97, respectively. The AUC0-∞, ratios of observed and predicted data in human were 1.63 (rat to human) and 1.57 (monkey to human), respectively. The rat and monkey PBPK models of famitinib were well established, and the PBPK models were applied in predicting pharmacokinetic of famitinib in human successfully. Hence, the PBPK model of famitinib in human could be applied in future drug-drug interaction study.

Objective To construct an expression system to produce the virus-like particles containing a part of the sequence of PSA mRNA, which are ribonuclease-resistant due to the encapsulation of the mRNA by bacteriophage MS2 coat proteins. Methods The PCR products of PSA cDNA fragments were cloned to TA vector pBS-T, then the targeted segments could be obtained when the pBS-T-PSA were digested by restriction endonuclease Hind Ⅲ and cloned to prokaryocytic expression vector pNCCL1. The recombinant plasmids named PNCCL1-PSA were transfected into E. Coli BL21-DE3 and induced to express with IPTG. Results The recombinant plasmids were successfully constructed. The bacteriophage MS2 coat protein which expressed in BL21 can self- assemble to form ribonuclease resistant virus-like particles and the PSA mRNA was encapsulated into virus-like particles. Conclusions The virus-like particle containing PSA mRNA can be expressed in prokaryocyte and it can be used as standard and control in detecting PSA mRNA. It provides a new, stable and ribonuclease-resistant RNA standard in RNA detection.

OBJECTIVETo investigate the therapeutic efficacy of Jinshuibao capsules in the treatment of silicosis.

METHODSA total of 270 patients with silicosis were randomly divided into treatment group (n = 141) and control group (n = 129). Both groups received conventional therapy. Additionally, the patients in the treatment group took 3 Jinshuibao capsules three times day for 2-3 courses of treatment (each course = 6 weeks). The therapeutic efficacy and the changes in tumor necrosis factor-α (TNF-α) and transforming growth factor-β(1) (TGF-β(1)) levels were observed after treatment.

RESULTSAfter treatment, cough, expectoration, chest pain, shortness of breath, and other respiratory symptoms were relieved significantly (P < 0.05). The treatment group showed significantly lower TNF-α and TGF-β(1) levels than before treatment and the control group (P < 0.05) and significantly higher forced vital capacity, forced expiratory volume in one second, and maximum mid-expiratory flow than before treatment and the control group (P < 0.05).

CONCLUSIONJinshuibao capsules can decrease inflammatory response, increase vital capacity and maximum voluntary ventilation, reduce airflow limitation, and improve quality of life and thus have good therapeutic efficacy in the treatment of silicosis.

OBJECTIVETo observe the therapeutic efficacy of tetrandrine tablets combined with matrine injection in the treatment of silicosis.

METHODSSixty-three patients with silicosis were randomly divided into treatment group (n = 33) and control group (n = 30). Both groups received anti-inflammatory, cough-relieving, and anti-asthmatic treatment. Meanwhile, the treatment group was given tetrandrine tablets (100 mg bid) and matrine injection (150 mg qd). There were 4 courses of tetrandrine treatment (each course = 3 months), with one-month intervals among them. Matrine injection was used for 15 consecutive days in each month. There were 2 courses of matrine treatment (each course = 3 months), with a one-month interval in between. The clinical symptoms, pulmonary function, serum superoxide dismutase (SOD) activity, and chest X-ray images were observed before and after treatment.

RESULTSAfter treatment, chest distress, chest pain, shortness of breath, and other respiratory symptoms were relieved significantly (P < 0.05). The treatment group showed significantly higher SOD activity than before treatment and the control group (P < 0.05) and significantly higher forced vital capacity and forced expiratory volume in one second than before treatment and the control group (P < 0.05). After treatment, 5 patients (4 stage II cases and 1 stage III case, all in rapidly progressive forms) in the treatment group showed smaller, lighter, and clearer shadows with decreased overall intensity on chest X-ray; 12 patients showed significantly fewer and clearer lung markings on chest X-ray.

CONCLUSIONTetrandrine tablets combined with matrine injection have some therapeutic effect on silicosis.
