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 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 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 investigate the changes in mechanics of respiration during perioperative period in patients undergoing orthotopic liver transplantation (OLT) without venovenous bypass. Methods Thirty patients of grade Ⅱ～Ⅲ according to the American Society of Anesthesiologists (ASA) classification, undergoing orthotopic liver transplantation without venovenous bypass, were included in this study. The respiratory parameters measured perioperatively included average airway resistance, peak inspiratory pressure, peak expiratory flow rate, dynamic compliance, work of breathing and respiratory drive. The complications of respiratory system during postoperative period were observed. Results Average airway resistance was decreased after abdominal cavity opening, decreased significantly at 5 min new hepatic phase and increased postoperatively. Peak expiratory flow rate and dynamic compliance were increased gradually after induction and increased significantly at anhepatic phase and new hepatic phase but decreased significantly on the first day postoperatively. Work of breathing was decreased after induction and decreased significantly at anhepatic phase and postoperative period. There was no significant difference in peak inspiratory pressure during operation. Compared with the values preoperation, the respiratory drive was decreased significantly during anhepatic phase and new hepatic phase. Total 35 times of postoperative respiratory complications occurred, which included pleural effusion, atelectasis, pulmonary artery hypertension, pulmonary interstitial edema and pnermonia. Conclusions There are obvious changes in respiratory mechanics during perioperative period of OLT, especially in postoperative period. Mechanical respiratory support is essential for patients until respiratory function recovers.

The daily intake levels and trend of polychlorinated dibenzo-p-dioxins(PCDDs), polychlorinated dibenzofurans(PCDFs), polychlorinated biphenyls(PCBs) of general population of several developed countries are reviewed. Based on the data of China, PCDD-Fs levels in Chinese human milk and blood were less than that of other countries, in addition, a daily intake of PCDD-Fs for Chinese general population was estimated in the present paper, the tolerable daily intake of Chinese general population was less than that the World Health Organization proposed.
