Objective To evaluate the value of three-dimensional(3D) ultrasonic examination in diagnosis of choroidal melanoma. Methods Twenty eyes(20 cases) proved as choroidal melanoma pathologically were reviewed retrospectively with their 3D ultrasonic examinations(OTI, Canada) preoperatively. Rotating-cut method in static stage was used to observe and measure the tumor. Results In 3D ultrasonic examination, 18 cases were diagnosed as choroidal melanoma according to tumor shape, choroidal depression, retinal detachment, CTH color change and cavernous phenomena of choroidal melanoma. The consistent rate of 3D ultrasonic examination and pathology was 90%. Conclusions 3D ultrasonic examination was valuable for diagnosis of choroidal melanoma, especially in observing and measuring the tumor.

"Four properties" of Chinese herb is the core content of drug property theory.Modern research on function and substantial property of "four property" has poor progress because there has di erent cognitions,ideas and methods.In this paper,main problems of "four property" are expounded through seven aspects,meanwhile,optional ideas and methods are proposed.

According to seven features of compatibility in preface of fragment of Bencaojing Jizhu(Annotation of Materia Medica),Qianjin Yaofang(Valuable Prescriptions for emergencies) and Zhenglei Bencao(Classi ed Materia Medica),the di erences among these three books and the transformation of seven features of compatibility are investigated.The results show that the number of traditional Chinese drugs which are related to seven features of compatibility in these three books is not the same,but the xed number is 197.Before the Song Dynasty,141 traditional Chinese drugs,relating to restriction,mutual inhibition,subjugation and assistance,were not added in Bencaojing Jizhu,while 55 were added.By making use of Jiayou Bencao(Materia Medica of Jia You Reign),Zhenglei Bencao added 34 traditional Chinese drugs which are related to restriction,mutual inhibition,subjugation and assistance,in fact 35 traditional Chinese drugs were added.Approximately 10 herbological books,such as Yao Dui and Tang Bencao(Newly-Revised Materia Medica),took part in the spread of seven features of compatibility.The quantity,name,classi cation and content of restriction,mutual inhibition,subjugation and assistance between Qianjin Yaofang and Zhenglei Bencao are similar,the fragment of Bencaojing Jizhu has great di erence between Qianjin Yaofang and Zhenglei Bencao.The classi cation of seven features of compatibility of traditional Chinese drugs in those three books obey their own systems,among which the fragment of Bencaojing Jizhu adopts the three rank classi cation methods,the others incline to be rationalized and detailed.This research is valuable for compiling the early herbology and discussing the compatibility theory of traditional Chinese drugs.

glycerol,and the best penetrable concentrations for it were 0.5%,0.5% and 0.2%,respectively.No obvious penetration efficacy was noted for glycerol.CONCLUSIONS: 4 kinds of penetrations enhances can increase the percutaneous absorption of DH under the certain concentration.

Short stature refers to the individual of the same race,gender and age,whose height is lower than the average height for about 2 standard deviations or under the 3rd percentile in the similar living environment.Its etiology mainly includes growth hormone deficiency,hypothyroidism,idiopathic short stature,Turner syndrome and so on.Short stature can be treated in childhood with recombinant human growth hormone (rhGH).Clinical evidence suggests that doctors should pay attention to thyroid hormone levels before and after rhGH therapy,so that they can offer thyroxine timely and maintain normal thyroid function for the children with hypothyroidism,which can improve the efficacy of rhGH in children with short stature.

OBJECTIVE: To seek approach for the protection of domestic pharmaceutical enterprises with immature creativity and to ensure drug accessibility. METHODS: An analysis was performed applying the theory of demand elasticity by comparing the attributes of health right and patent right etc based on TRIPS protocol and the related practice abroad. RESULTS & CONCLUSIONS: For a developing country, China should give top priority to the short-term urgent needs, such as to meet people's medication demands, followed by meeting the long-term demands, such as to encourage independent intellectual property rights. Hence, drug accessibility-related system in drug patent system should be evolved step by step.

Objective:To evaluate the analgesic effect of botulinum toxin type A (BTX-A) in osteoarthritis model and the changes of Nav1.8 protein expression in spinal ganglia changes.Method:Animal model of knee osteoarthritis (KOA) was established by intra-articular injection of 4％ papain solution 0.3ml into SD rat right knee.After the formation of arthritis,they were randomly divided into two groups at the 2nd day:BTX-A group (n=10):intra-articular injection of 5μl BTX-A 0.1IU;WFI group (n=10):intra-articular injection of 5μl water.No papain or BXT-A was given to the sham group (n=10).At the 1st,3rd,5th day after injection,we tested the pain behavior,thermal pain threshold,and sodium channel 1.8 (Nav1.8) protein expression in spinal ganglion by using immunohistochemistry.Result:Analysis of spontaneous pain behavior showed abnormal gait caused by rat osteoarthritis.Comparing with the WFI group,abnormal gait caused by osteoarthritis improved significantly in BTX-A group.At day 5 it improved more significantly than day 1 and day 3.Thermal pain threshold of BTX-A group increased more than that of WFI group (P＜0.05) at any time point.Abnormal high Nav1.8 protein in model rats decreased in spinal ganglia for BTX-A group.Conclusion:The intra-articular injection of BTX-A may play the analgesic effect in the model of KOA by down-regulating of the expression of Nav1.8 protein in spinal ganglia and reduction in the central sensitization to pain stimulation.

Syndrome attribute determined by signs and symptoms of an animal model through intervening in the clini-cal and animal syndrome differentiation standards is not standardized, objective or rigorous. The signs and symptoms of people are difficult to be expressed fully and accurately in the animal body correspondingly. The signs and symptoms of animals are mostly without any syndrome information. There are no difference of signs and symptoms among differ-ent modeling methods. Hence, it is difficult to determine the syndrome-attribution of an animal model based on signs and symptoms. There are two problems in drug reduction to determine syndrome-attribution of animal models. Firstly, for drug reduction, only one group is used in the animal subject. There are no other two groups or multi-groups of drugs compared with each other to confirm the syndrome-attribution of animal models. Lots of research results indicat-ed that multiple drugs with different functions can change the state and the objective index of the same animal subject. Secondly, employing the control principle, adjusting and improving the best drug for the animal subject were used to determine the syndrome-attribute. However, these studies cannot be operated, because the preliminary studies, such as the essence of syndrome, have not provided generally recognized effect indexes and index groups.

Studies showed that animal model of the so-called simple syndrome currently have corresponding modern medical disease without exception. Even such animal model is called simple syndrome model, its properties is a cer-tain modern medicine disease. There is no specific corresponding relationship between the syndrome-attribution and the syndrome. The signs and symptoms differentiation and abnormal physical and chemical detection indices after pathogen-modeling of traditional Chinese medicine (TCM) cannot be determined since there are no specific corre-sponding relationships. The study on disease-syndrome combination model contains both modern medical modeling method and TCM modeling method. This type of modeling method has its own existing shortcomings. Meanwhile, two modeling methods used in the model establishment have uncertain relationship. The disease-syndrome combination model is usually not established in the comparison among different syndromes of one disease. Therefore, it has no ex-clusive attribute. There are many problems existed in the TCM modeling method, disease-syndrome combination modeling method, and syndrome-attribute evaluation methods. The basic reasons are the wide difference between symptoms and signs for diagnosis in modern medicine disease. There are a few symptoms and signs for diagnosis in modern medicine. But there are much more symptoms and signs for syndrome differentiation of the same disease. Many symptoms for syndrome differentiation are unknown for its source of origin existed in a virtual state. It caused that many virtual syndromes abstracted by virtual symptoms, and was reflected by the relevant standards. It leads to devastating consequences for the development of animal modeling method.
