This article reviewed many different opinions on teeth-marked tongue, and made a discuss on the differentiation of symptoms and signs based on clinical practice. We consider that the teeth-marked tongue indicates the diseases that are caused by pathogenic dampness, while the correlation between such diseases and spleen deficiency still needs study.

Adenoid cystic carcinoma is regarded as one of the most common malignant tumors in parotid gland. The local control rate and long term survival rate of salivary gland adenoid cystic carcinoma, which tends to spread along the perinerve and metastasis distantly, are not good. This review focused on the advances in the treatment of adenoid cystic carcinoma of parotid gland.

Activation of HGF/Met has been complicated in tumorigenesis, invasion and metastasis of various tumors. We summarize current knowledge on their association with invasion of thyroid carcinoma. By discussing the expression of Met and its possible mechanism and analyzing the activation of Met with tumor motility, angiogenesis and inflammatory reaction, we conclude that the research of the possible role of HGF/Met in thyroid carcinoma will advance knowledge on the diagnosis and management of this disease,as well as tumor invasion.

Alveolar echinococcosis, caused by Echinococcus multilocularis infection, is a highly deadly zoonotic parasitic disease. As a benzimidazole compound, albendazole has a strong and broad-spectrum anti-parasitic action. For alveolar echinococcosis patients that are unwilling to receive surgical treatment, lose the timing for surgery, or are intolerant to surgery due to poor physical status, administration of albendazole may delay disease progression. Recently, a large number of advances have been achieved in experimental studies on alveolar echinococcosis. In order to increase the understanding of the therapeutic efficacy of albendazole for alveolar echinococcosis, this review summarizes the advances in albendazole treatment for alveolar echinococcosis, so as to provide insights into the clinical treatment of alveolar echinococcosis with albendazole.

Objective To investigate the safety and efficacy of domestic contrast iodixanol injection in the application of interventional neuroradiology. Methods A total of 442 patients from 11 research centers using iodixanol injection for whole brain DSA examination or interventional therapy were enrolled in a prospective,multicenter,and non-controlled clinical trial. The recording and evaluation indicators included the adverse reactions after drug treatment,changes of creatinine and urea nitrogen indicators before and after drug treatment,DSA types,DSA effects,the dosage of contrast agent,etc. The renal function damage, incidence of adverse drug reactions,and image quality were counted and analyzed. Results All the 442 patients were completed the examination or treatment. (1)All the results of intraoperative angiography achieved excellent,including 98. 2% (n = 434)were excellent and 1. 8% (n = 8)were good. There were significant differences in the comparison of angiographic results in the 4 different types of DSA (SIEMENS,PHILIPS,GE,and TOSHIBA)(χ2 = 31. 518,P < 0. 001 ). (2 )Only 1 patient had increased serum creatinine > 44. 2 μmol / L. There was no urea nitrogen abnormality of clinical signifi-cance. None of the patients had renal insufficiency. (3)Three patients had adverse drug reaction (0. 7%) during procedure,including 2 patients had dermal allergic reactions and 1 patient had transient blurred vision. Conclusion Domestic iodixanol injection is safe and effective and has less adverse reaction in the clinical application of interventional neuroradiology. The different types of DSA may impact on the contrast image quality.

Objective To observe the long-term toxicity of sustained-release dropping pills of Rhynchophylla total alkaloids in rats.Methods 80 Wistar rats were randomly divided into high dose group, middle dose group, low dose group and normal group. The rats were consecutively drenched for 12 weeks. The general status of the animals was observed daily in medication duration and body weight, daily appetite, quantity were recorded every 2 weeks. All animals were sacrificed on drenched 12 weeks and 2 weeks after discontinuation, then the content of WBC, RBC, Hb, PLT, LYM, NEU and ALT, AST, ALP, BUN, Cr were detected. Ratio of viscera was measured and the major organs were examined by the pathology.Results Continuous intragastric administration for 12 weeks after high dose group rats, poor diet, weight growth was slow;no significant changes of Hematology was found;The ALT, AST and ALP of high dose group rats increased[respectively(77.5±11.9)U/L,(210.4±21.7)U/L,(220.6±19.8)U/L], compared with the blank control group[respectively(55.2±12.1)U/L,(180.4±21.3)U/L,(190.3±22.6)U/L], the difference was statistically significant(P<0.05). The ratio of liver body in high dose group(3.86±0.29)was higher than the control group(3.52±0.25), the difference was statistically significant(P<0.05). And liver degeneration, focal necrosis was found.Conclusion The main chronic toxic damage is liver damage caused by sustained-release dropping pills of Rhynchophylla total alkaloids of long-term large delivery.

The platelet glucoprotein(GP)Ⅱb/Ⅲa inhibitors prossess inhibiting platelet aggregation effectly. As new drugs of antiplatelet, they are different in mechanism with action, application and dosage between the Ⅱb/Ⅲa inhibitors and other tradional antiplatelet drugs such as aspirin or clopidogrel. In familiar with the pharmacologic action and clinical application of Ⅱb/Ⅲa inhibitors is important for endovascular interventional radiology, especially with important significance for obtaining high quality neuro-endovascular stenting in the perioperative period.

Purpose:To investigate the type of surgery appropriate for substernal benign thyroid tumor. Methods:A study of 19 substernal benign thyroid tumors operated between 1990 and 1999 was made. Surgery via cervical collar incision were performed in all cases. Results:Among them 4 cases was adenoma, 16 cases goiter. There were no complications except for 1 case with recurrent laryngeal nerve paralysis. Conclusions:Surgery via cervical collar incision for substernal benign thyroid tumors is safe.

Neutrophils play an immune defense role by releasing the proteases such as neutrophil elastase and myeloperoxidase to form neutrophil extracellular trap （NET） and participate in the inflammatory response of various liver diseases， but the excessive release of NET may worsen liver tissue damage and has thus become one of the risk factors for liver diseases. In recent years， studies have shown that the excessive release of NET can promote the progression of liver diseases （such as viral hepatitis， nonalcoholic steatohepatitis， and hepatic ischemia-reperfusion injury） to liver cancer， and clarifying the mechanism of action of NET is of great importance for the diagnosis and progression of liver diseases. Therefore， this article elaborates on the latest research advances in NET in liver diseases， so as to provide new insights into the diagnosis and treatment of liver diseases and the prevention of liver cancer.

OBJECTIVE: To explore the relationship between metabolic syndrome( MS) and occupational stress among workers in high altitude area. METHODS: A cross-sectional study was conducted in 940 workers as research subjects who were engaged in petroleum smelting,thermal power generation and financial management et al. in high altitude area. A questionnaire survey was conducted using the Occupational Stress Inventory-Revised for occupational stress, The occupational health examination was performed to measure waist circumference,blood pressure,blood sugar and blood lipids. RESULTS: The abnormal rates in obesity,triglycerides,high-density lipoprotein,blood pressure and fasting blood glucose were 28. 3%,16. 3%,14. 3%,13. 3% and 6. 5%, respectively. The detection rate of MS was 5. 0%( 47/940). The multivariate logistic regression analysis showed that the risk of elevated MS decreased with the increased of occupational stress level( P < 0. 05),and the risk of elevated MS increased with the increased of occupational stress reaction severity( P < 0. 05),after adjusting the confounding factors of gender and labor nature. CONCLUSION: The higher occupational stress reaction of the workers in high altitude area,the higher the risk of MS.
