Accurate alignment of knee implants is essential for the success of total knee replacemem.Recently,computer-aided navigation systems have become available,and the results showed more accurate and consistent installation of knee implants.The technology has evolved rapidly with widespread and continue to be developed.The current computer environmem and graphical user interface will become more user friendly and thus gain more widespread acceptance among experienced surgeons With this technology growing and systems evolving,computerized navigation will become the standard of care in knee reconstructive surgery.The key of future studies is to evove less invasive tracker anchoring systems,electronic balancers and computerized saws.A hybrid technique between image-based and image-free methods may develop to produce image-enhanced navigation.It should be an intermediary step between current technology and a fully robotic system.

OBJECTIVE： To discuss about the key and entrance points of the development strategy of Chinese materia medica in the new century.METHODS： Some important items,such as difficult problems which Chinese materia medica facing to at present,new way to research into its effective substance bases,innovation on the theory and “ molecular targets” of Chinese materia medica,were analyzed.RESULTS ＆ CONCLUSION： Chinese materia medica industry would become a most important pharmaceutical industry in China and really walk up to the whole world if traditional Chinese herb medicine supplies“ international language” for its exchange,qualitative and quantitative standards on judging the essence of its prescriptions and builds up its“ earmark” of Chinese materia medica industry.Based on the train of thought of this paper,suggestions how to promote the development of Chinese materia medica in the new century are put forward.

Since the first session of Chinese anti-inflammatory immunopharmacological society in 1982,many breakthroughs of immunological research have been made in western countries,such as identification of pathogens by natural immune cells,regulation of immune response,lymphocyte differ?entiation and development. At the same time,much progress has been achieved in anti-inflammatory and immunological research in China,especially in the field of basic scientific issues in immunology, frontier and hot topics,immunological mechanisms of major diseases and related drugs. The course of development of Chinese anti- inflammatory immunopharmacological research has experiences various stages,such as ″follow ″ in the past to ″work together ″ and to ″lead ″ in some research areas in today′s international immunology.

The cells sense direction is closely related with the proteins that contain PH (pleckstrin homology) domain. PH domain has been found in about 60 proteins, many of which could activate the sequent events of signal transduction via combining with the related binding sites on the surface of chematactic cel ls. The characteristics of this combining are: a.rapid and transient; b.It is only related to the concentration gradient of surroundings outside cells, whi ch is the base of spatial model; c.The distribution of the binding sites on th e cell membrane changes when the researchers altered the position of the chemoat tractant. This is the base of temporal model. To deeply investigate the effects of all kinds of proteins which contain PH domain on cells sense of direction will greatly promote the research of this field, and hence, has great theoretica l significance.

AIM:To study of effects of Panax notoginsengnoside(PnGL) on neutrophil(Neu) functions in carrageenin(Car) induced subcutaneous air-vesicle synovitis in rats and its mechanisms METHODS:Rat air-vesicle synovitis model was established with sc Car(25mg/kg) Neu count,the phagocytosis of Neu,the realease of O2 ?- from Neu and the level of Neu-i were measured with test tube diluting method,staphylococcus aureus phagocytosis method,cytochrome C reduction method and Fura-2 fluorescence technique respectively RESULTS:At 12h after Car used,Neu count of exudates elevated,phagocytosis rate and index of Neu and the release of O2 ?- from Neu increased obviously,suggesting that Neu was in an activated state Mea_nwhile,the level of Neu-i elevated significantly PnGL 60～240mg/kg ip,30min before and 6h after Car sc,reduced Neu count of exudates,inhibited phagocytosis functions and the increase of i level of Neu in a dose-dependent manner There was a significant correlation between the reduction of Neu-i and the inhibition of Neu phagocytosis functions and the release of O2 ?- from Neu Dexamethason had similar effects on Neu functions to PnGL,but with no effect on the level of Neu-i CONCLUSION:The reduction of Neu-i level and the subsequent inhibition of Neu functions is one of the important anti-inflammatory mechanisms of PnGL,which is different from that of Dex

OBJECTIVE:To investigate the characteristics and general regularity of ADR induced by Danhong injection,and to provide reference for rational drug use in the clinic. METHODS:Using“Danhong injection”and“ADR”as keywords,retrieved from CJFD,literatures published during 2005-2015 were collected and analyzed statistically in repsects of patient’s gender and age,disease and allergic history,drug combination,occurrence time of ADR and clinical manifestations,etc. RESULTS:A total of 24 literatures were collected,involving 360 cases. Female patients were more than male(66.11% vs. 33.89%);ADR often oc-curred within 30 min during medication(169 cases,46.94%);main clinical manifestations were lesion of skin and its appendents (163 cases,42.89%), systemic injury(72 cases,18.95%). The severe one would suffer form allergic shock. CONCLUSIONS:Great importance should be attached to the indication of Danhong injection,treatment based on syndrome differentiation,rational drug use and close monitoring. Constant vigilance is necessary to the occurrence of ADR.

Objective To explore the effect of prenatal inflammation on rat offspring's blood pressure and behavioral performance.Methods Twenty-four time-mated Sprague-Dawley(SD)rats were randomly divided into three groups,i.e.control,zymosan and LPS.On their gestation days 8,10,12,the pregnant rats received i.p.injections of sterile saline,0.79 mg/kg zymosan or 0.79 mg/kg LPS respectively.When the offspring were sixty weeks old,eight pups were chosen randomly for the later study.Their serum TNF-? level was detected by ELISA using tail blood,arterial blood pressure was measured by tail-cuff method,and their behavioral performance was detected in Morris water maze test.At the end of the experiment,the brains were rapidly taken from the sacrificed offspring,cut into sections and stained with H&E method to investigate the structural changes of hippocampus.Results Compared with control group,all offspring from the inflammation groups showed increased serum level of TNF-?,increased systemic arterial blood pressure,long latency in finding the safe platform and decreased number of neurons in CA1 region of hippocampus.Conclusion Prenatal exposure to LPS or zymosan results in hypertension and disturbance of learning and memory.

Chinese patent medicines have unique advantages in treatment of diabetes. This article provides a comprehensive review of the classification, analysis and evaluation of the post-marketed Chinese patent medicines for diabetes and proposes that pure TCM preparations and Chinese/western compound preparations should be considered differently in regards to their clinical uses. TCM symptom-complex differentiation is the common guideline for rational use of both pure TCM preparations Chinese/western compound preparations. Moreover, the Chinese/western compound preparations should be used in accordance to the indications of the western medicine contained and strictly under the physician's instruction. Education and training of rational medication usage, basic and clinical study on post-marketed medicines are important measures to control and reduce medication risk.

Aim Curcumol and Zedoary Turmeric Oil (ZTO) were prepared to liposome, which were used to study the anti-hepatoma effect, and its mechanism that was expected to provide theoretical support for the clinic anticarcinomal use of Zedoray Rhizome Abstracts.Methods Curcumol and ZTO were prepared to liposome by mechanical diffusion and ultrasonic techniques.Proliferation of HepG2 cell in vitro was observed with curcumol and ZTO by MTT assay. Apoptosis of cells was observed by staining with Hoechst 33258/PI and laser confocal scanning microscopy (LCSM). Expression of COX-2 mRNA and VEGF mRNA of HepG2 cell was investigated by RT-PCR.Results Envelopment ratios of curcumol liposome and ZTO liposome were 86.2% and 74.5%,respectively.Curcumol and ZTO inhibited proliferation of HepG2 cell by MTT assay.Compared with control group, Curcumol and ZTO increased the apoptosis rate of HepG2 cell significantly (P
