The problem of intellectual property of traditional Chinese medicine were discussed, the TCM protection system and patent protection system are studied. The author puts forward some deficiencies of the existing protection system, and puts forward some improvement methods possible.

Large number of TCM ancient books, the literature, has a long history and complicated contents, including the principles, methods, prescriptions, medicines and other various aspects. How to obtain and make use of knowledge in ancient books, we must establish a set of relatively precise knowledge and semantic relation networks. Knowledge yun performing reasonable rebuilding of TCM literature, containing much TCM knowledge and information, will be an important way for knowledge findings.

Thirty-four patients with chronic lingual tonsillar hypertrophy were treated in our department from 1994 to 2000. There were 18 males and 16 females ranging in age from 21 to 60 years old. The clinical feature of lingual tonsillar hypertrophy usually appeared a series of pharyngeal symptoms, such as foreign-body sensation, sore throat, speech change, difficulty in swallowing, dysapnea and obstructive sleep apnea. The CO2 laser surgical lingual tonsillectomy was used for these patients. Result showed that the cure rate was 100% without any serious complications by following up 2 months to 3 years. The variety of presentations of lingual tonsillar hypertrophy and methods of surgical treament were discussed.

Result of Bencaocogical studies on Changpu showed that it originated from two different source, one is Shuichangpu (Asorus calamas) while another is Shichangpu (A.tatarinowii and A.gramineus). Usually, Changpu grown on stony ground was referred to as Shichangpu.Jujiechangpu is a kind of Changpu with 9 nodal rings within an "inch" on its root stock,but that which is used in Northwest China is an cntirely different herb Anemone altaica.

Cataract is still the main blinding eye disease,and it is a major goal of fighting blindness in China.In the past years,the diagnosis,treatment technology and equipment have made great progress.With the further understanding of this disease and increasing requirement of patients for the quality of life,the standardization,safety and efficacy of the clinical diagnosis and surgical outcomes of cataract have become much more important.So the relative clinical examination approaches,modified operating skills,new surgery development and application as well as novel type of functional IOLs design advance rapidly,which provide an expensive space for the selection of the treatment for cataract.High quality of cataract surgery depends on preoperative precise biometry,reasonable operating scheme targeting at personality,suitable functional IOL,less intra-or post-operative complications,effectively avoiding treatment risk and correctly processing disadvantageous factors affecting postoperative visual quality.Therefore,the management of cataract surgery is a systemic procedure.The issue of improving ophthalmic examination,new cataract surgical technique and new IOL emerges as the time requires.How to make up individual-based treatment options for patients,better improve postoperative visual quality,enhance the safety of operative procedure,reduce operative complications is the challenges and unremitting goal for the ophthalmologists.

Asialoglycoprotein receptor(ASGPR),also called galactose receptor,is predominantly expressed on the sinusoidal surface of mammalian hepatocytes and is involved in many physiological functions.For many years ASGPR has been applied for targeting hepatocytes in drug and gene delivery and for functional mapping of the liver,and considerable progress has been made.ASGPR-mediated liver-targeted drug delivery mainly involved anti-tumor drugs and cholesterol-lowering drugs,etc.Liver-targeted gene delivery was often seen in antisense drugs.The research of hepatic imaging mainly involved the evaluation of liver function and identification between hepatocellular carcinoma and hepatic metastasis of tumors.In addition,researchers have also extended its applications to some new fields,such as three-dimension culture of hepatocytes,hepatocytes screening,and hepatocytes transplantation.New achievements in studies of ASGPR-mediated liver targeting are reviewed in this article.

Metastatic colorectal cancer is a major cause of cancer-related mortality. Surgical resection of all known metastatic disease can be curative in selected patients. The majority of patients,however,require systemic chemotherapy as optimal palliative treatment for their disease. For years,effective treatment for advanced colorectal cancer was limited to fluorouracil. In the 1990s,two additional agents,irinotecan and oxaliplatin,were found to have activity against advanced colorectal cancer. Recently,new molecular targeted agents,bevacizumab and cetuximab,were for the first time demonstrated efficacy. Herein,we review recent developments in treatment for metastatic colorectal cancer and implication for optimal treatment in these patients.
