Acupuncture is widely used as an alternative therapy with few side effects because of its simple manipulation and low cost. However, accidents may occur if the practitioner uses it improperly. Early in the Qin dynasty, the Canon of Medicine mentioned that improper use of acupuncture could cause injury to the body and even death, and it systematically described the occurrence and prevention of acupuncture accidents. Physicians in the successive dynasties frequently reported it, and realized that the manipulation skills were significantly important in preventing the occurrence of acupuncture accidents. Since the 1950s, acupuncture accidents had been effectively prevented because of the improving of acupuncture instruments, enhancing of the quality of the practitioners, popularizing of sterilization and disseminating of anatomic knowledge. Nevertheless, with the renovating of acupuncture techniques, new accidents may occur constantly. The prevention of acupuncture accidents still should be an arduous task for acupuncturists. Nowadays, acupuncture therapy is being used in more than 140 countries, and acupuncture accidents due to improper application are increasing. Prevention of acupuncture accidents has become a global issue deserving of great attention.

Moxibustion is an important invention of the Chinese nation, which originated as early as in the clan commune period of the primitive society. The literature records on moxibustion can be traced back to the Warring States Period (475 B.C. to 221 B.C.). Doctors through the ages made considerable progress and published a great number of books on moxibustion. Moxibustion has been applied in treating a great range of diseases. Since the 1950s, the treatment scope of moxibustion has been expanded, and the therapeutic methods of moxibustion are becoming increasingly rich and varied, and great progress in research on the mechanism of moxibustion has been made. Moxibustion was once popular in Europe after its dissemination to the West in the seventeenth century, and the practitioners invented some new methods of moxibustion. Japan is the country in the West where fruitful efforts have been made in research on moxibustion. In modern times, moxibustion has been used for health protection, and the scientists are paying great attention to the experimental research on moxibustion.

BACKGROUND : Chitosan, derived from chitin, has a poor solubility which limits its application greatly. For improving its dissolubility, according to the feature that intramolecular hydroxy and amino group in chitosan are easy to be chemically modified, and functional groups are introduced to improve its solubility and functionality to widen the range of its application, which has become one of the new trend of development for investigating the application of chitosan. OBJECTIVE: To sum up the research advancements in the application and modification of chitosan in carboxylation,acylation, alkylation, etherification, etc.RETRTEVE STRATEGY: The relevant articles published in English between 1998 and 2007 were searched for in Pubmed database with the key words of "chitosan, modification", and the relevant articles published between 1998 and 2007 were searched for in Elsevier Science database with the key words "chitosan, modification" and search "derivate" within search results in English. Articles closely related to the structural modification and application of chitosan were involved, and repetitive and old studies were excluded.LTTERATURE EVALUATION: Totally 154 articles were selected, and 30 of them are accorded with the inclusive criteria,including 5 are reviews, and the others are clinical or experimental studies.DATA SYNTHESTS: The intramolecular hydroxy and amino groups in chitosan are mostly modified because they are easy to be chemically modified. Recently, reports lay particular emphasis on the modification in carboxylation, acylation,alkylation, etherification, etc. Functional groups are introduced to improve its solubility and functionality to widen the range of its application.CONCLUSTON: The water-solubility of chitosan can be improved through structural modification and introducing multifunctional group, which can also bring about much more special efficacies.

Sorafenib is a novel oral multikinase inhibitor that inhibits Raf kinase because of its anti-proliferative property. Sorafenib also inhibits receptor tyrosine kinases of multiple proangiogenic factors, such as VEGFR-1/2/3 and PDGFR-β. The combina-tion of both its anti-proliferative and anti-angiogenic properties makes sorafenib an attractive agent in cancer treatment. To date, sorafenib is the only approved systemic treatment for patients with hepatocellular carcinoma. The most common adverse events of this inhibitor included hand-foot skin reactions, nausea, diarrhea, weight loss, and hypertension. These adverse events can severely affect patient compliance, which may negate the effect of therapy. Correct understanding and treatment of these adverse events can improve clinical outcome. This paper discusses the clinical aspect of sorafenib-induced adverse events and the molecular basis behind their toxic-ity. Recommendations for the management of the adverse effects are also provided.

Objective To investigate the subjective well-being and its influencing factors of the advanced elderly in the community. Methods Totally 409 cases aged 80 years and over in five communities of Hang zhou city were surveyed using Memorial University of Newfoundland Subjective Well-bing Scale. Results The subjective well-being of the advanced age people was at a high level.The cases with good hearing,well eyesight,income from own source,monthly income between 1000-3000 yuan,health satisfaction and frequently or occasionally regular interest in the activities had higher subjective well-being(all P＜0.05).Subjective well-being was not significantly affected by age,sex,level of education (P＞ 0.05). Conclusions Subjective well-being of aged people is mainly affected by state of health and economic resources.

Recent findings indicate that metastasis-associated gene in colon cancer 1 ( MACC1 ) has an abnormal high expression in most malignant tumors.As a key regulator of HGF-MET signal pathway,MACC1 could obviously up-regulate the expression of MET and promote cancer cell's movement,invasion and metastasis.Further studies will shed light on elucidating the mechanisms of metastasis and may provide a new method for targeted therapy.

Sepsis is the leading cause of acute kidney injury (AKI) in pediatric intensive care unit.Development of AKI during sepsis increased patient morbidity,predicts higher mortality and days of stay in the intensive care unit.The mechanisms behind AKI in sepsis remain controversial but were believed to be complex and multi-factorial.The pathophysiology of AKI in sepsis involved intrarenal hemodynamic changes,endothelial dysfunction,infiltration of inflammatory cytokines.The new markers of neutrophil gelatinase-associated lipocalin as the representative is helpful for early diagnosis of AKI.Renal replacement therapy (RRT)is the main treatment of sepsis related AKI.At present,the model,dose and exact timing of RRT is not well defined.A widely accepted viewpoint is that the injury stage of RIFLE diagnostic criteria and fluid overload up to 10％ ～ 20％ is the beginning of the most appropriate chance of RRT.

Objective:To explore the medical undergraduate teaching method of ECG. Methods:random sampling in the practice of medical undergraduates in our hospital ,2013 medical undergraduates as the experimental group, 2012 medical undergraduates as control group, two groups of 40 (male, female 20), age 22~23 years old, the experimental group internship period adjustment of ECG in 2 week internship, ECG during the internship period, by the junior high the doctor, according to a set of prior to the development of the teaching plan, practice teaching, the control group had no ECG internship content; in the two groups before and after the end of internship, were an ECG, theory of knowledge, operation and map reading test. Results:In the experimental group in the ECG theoretical knowledge, operation method, normal electrocardiogram, abnormal electrocardiogram exam scores, were more than that of the control group, there was significant difference in two groups(x2=22.321, x2=37.883, x2=31.179, x2=10.66;P<0.001). Conclusion: According to undergraduate medical situation, summarize the clinical teaching process ideas, enhance the practice ability, is before the practice was significantly increased in the reading and analysis abilities of ECG, far more than the control group. The teaching plan is feasible and effective;it is worth further exploration and promotion.
