Lysimachiae Herba and Desmodii Styracifolii Herba are common traditional Chinese medicines for treating lithiasis. Both of them have efficacies of clearing heat, diuresis and eliminating calculi. However, there are some differences in their clinic applications. The former is mainly used to treat hepatolithiasis, gallstones, jaundice, stranguria and gout; Whereas the latter is mainly used to treat urinary calculus. In this paper, the pharmacological effects of Lysimachiae Herba and Desmodii Styracifolii Herba on removing calculus, choleresis, anti-inflammation and oxidation resistance were compared and analyzed based on document retrieval. In conclusion, both of them show the preventive and therapeutic effects on kidney stones and gallstones. Particularly, Desmodii Styracifolii Herba has a better effect in treating the kidney stones, while Lysimachiae Herba has a better effect in treating cholesterol gallstones.

Objective To improve the recognition in clinical features,diagnosis and treatment of POEMS syndrome.Method Twenty-one cases of POEMS syndrome were analyzed retrospectively.Results The major clinical features were shown as follows: 21 cases of polyneuropathy, organomegaly, edema and skin changes, 13 cases of monoclonal plasma proliferative disorder, 19 cases of endocrinopathy, 1 case of sclerotic bone lesions, 1 case of Castleman disease,5 cases of papilledema.Conclusions POEMS syndrome is a rare multi-system damage disease.Screening for POEMS syndrome with serum protein electrophoresis, immunofixation electrophoresis,electromyogram and radionuclide bone scanning are essential for all patients with unexplained peripheral neuropathy or multi-system damage.If the index of suspicion is high enough, bone marrow cytomorphologic examination or biopsy with immunohistochemical staining may be required,in order to make an early diagnosis and try to avoid misdiagnosis and mistherapy.

Objective To analyze the main sources of dioxins pollution in fishes samples. Methods The principal components analysis was employed to identify different dioxin emission sources data and to analyze the environmental and aquatic samples. The Principal Component Analysis seems to be a powerful tool for source identification with the ratio of each concentration of the 2,3,7,8-subtituted congener to the concentration of the total 2,3,7,8-subtituted congeners. Results The result obtained from Principal Component Analysis showed that there were different dioxin compositions between chemical emission sources and other emission sources. Conclusion The pollution sources of PCDD and PCDF polluted aquatic life from different countries,regions are not the same.

Objective To observe the anti-androgenic activity of two pyrethroids (cypermethrin and fenpropathrin) in vivo. Methods SD rats aged 6 weeks were castrated ,and then housed for one week. The rats were randomly divided into groups, six in each: negative control group,cypermethrin and fenpropathrin group, positive control group. The rats were subcutaneously injected with testosterone propionate (TP) 100 ?g(/kg?d)for 7 consecutive days. Peanut oil, cypermethrin [ 45, 90, 180 mg/(kg?d)], fenpropathrin[10, 20, 40 mg/ (kg?d) ], flutamide[ 20 mg(/kg?d) ] were subcutaneously injected for 7 consecutive days at the same time. The sex accessory glands and serum hormone were detected. Results Compared with the negative group, no significant differences were observed in the sex accessory glands/tissues (seminal vesicles with coagulating glands, dorsolateral prostate, the ventral prostate and levator ani muscles) and the levels of serum hormones of the pyrethroids groups. Compared with the negative group, the masses of all the sex accessory glands/tissues decreased significantly in the positive group . Compared with the negative group, the level of LH increased significantly in the positive group. Conclusion No obvious anti-androgenic effects induced by cypermethrin and fenpropathrin in castrated SD rats has been observed.

Objective To understand the situation of benzene series compounds pollution inside some Passenger cars in Tangshan and provide data for the formulation of corresponding countermeasures for the prevention and control of the pollution. Methods One hundred and twenty-two cars used for different periods of time were selected from March, 2009 to May, 2009 and the concentrations of benzene,toluene and xylene were determined.At the same time the basic situation (car type, date of manufacture) was investigated with questionnaire. Results The disqualified rate of benzene, toluene, xylene were 14.8%(18/122), 26.2%(32/122) and 20.5%(25/122) respectively. Eighty-one cars did not meet the standard, accounting for 66.4 %(81/122). The median of benzene, toluene, xylene in the cars used within six months were 0.086, 0.900, 0.400 mg/m3 respectively. The exceeded rate of benzene, toluene, xylene inside the cars which were used for not more than six months were 28.6%(10/35), 57.1%(20/35), 60.0%(21/35) respectively. The concentrations of benzene series compounds decreased gradually later on. The concentrations of benzene inside the cars with adsorbent were lower, the concentrations of toluene inside the highgrade cars were higher and the concentrations of xylene inside the cars with leather seats was higher. Conclusion Benzene, toluene, xylene pollution inside cars has been showed in this investigation in Tangshan. The concentrations of benzene series compounds are associated with using time, adsorbent, car grade and the seat material.
