Objective To study the anticoagulation effect of low molecular weight heparin ( LMWH) on hemodiafiltration by different forms of administration. Methods Twenty-four uremic patients undertook hemodiafiltration were divided into ia and iv group randomly, acecepted single injection of LMWH. LMWH was administered to 12 patients by arterial injection ( predialyzer), while in the other 12 patients by venous injection (postdialyser). The APTT were measured before treatment and at 1 h,2 h,3 h time points after treatment in all patients. The dialysis fluid and blood levels of LMWH were measured at 2 minutes,5 minutes,1 h,2 h,3 h time points after the treatment started. Results The LMWH levels during hemodiafiltration were significantly higher in iv group than ia group (0.457 ± 0.073 ) U/ml vs. (0. 217 ± 0. 053 ) U/ml, t = 9. 702, P = 0. 001 ). However there were no significant APTT, dialyzer residual substance differences between two groups (P ＞ 0. 05 respectively )Conclusions Different ways of drug administration resulted in significantly different blood levels of LMWH, but did not affect the anticoagulant effect during hemodiafiltration, which would be related to LMWH absorption on dialysis membrant.

Objective:To explore the influence of chaperone tapasin on HLA E expression on cell surface.Methods:The infection method was used to transfer the recombinant retrovirus expression vector which was constructed with HLA E molecules on target cells was detected with FACS technique.Results:Exogenous HLA E expression on T2 cell surface was detected with 74.13% and no HLA E expression was detected on control cells and that was transfected with empty vector.Conclusion:It is possible that the expression of HLA E molecules on cell surface involves in TAP independent mechanism.

The canonical or official functions of formulae and traditional Chinese patent medicines and simple preparations are generally existing issues in terms of non-integrated presentation(short of the functions aiming at pathogeny and pathogenesis),confusion of logical relation and inconsistent indication etc.It causes a biggish negative influence on traditional Chinese medicine.This article has analyzed and explained these questions using a lot of illustrations,and given concrete ways of settling these issues.

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.

"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.

This study was aimed to observe the clinical curative effect of Thesium Chinese tablets in the treatment of chronic bronchitis (syndrome of phlegm heat in the lung). A total of 100 cases of chronic bronchitis (syndrome of phlegm heat in the lung) were randomly divided into two groups. The control group was treated with anti-inflamma-tion, relieving cough and asthma, phlegm removing and oxygen inhalation, maintenance of water electrolyte balance and other symptomatic treatment. In the treatment group, on the basis of treatments in the control group, Thesium Chinese tablets were given at the dosage of 1.6 geach time, 3 times a day. Both groups were treated for 1 course of 10 days. The results showed that clinical symptoms and traditional Chinese medicine (TCM) syndromes of quantizing integral were improved after treatment in both groups. And the therapeutic effect of treatment group was significantly better than the control group (P< 0.01). Thesium Chinese tablets can effectively shorten the time of clinical symptom improvement time, obviously improve the level of Ig among elderly patients with acute exacerbation of chronic bron-chitis, and enhance the immune function. It was concluded that the Thesium Chinese tablets can effectively improve the quality of life among patients with chronic bronchitis (syndrome of phlegm heat in the lung).
