The definition and diagnostic threshold of early caries have been changed to even earlier stage of subclinical level in recent years. This article tries to introduce the significant changes in the area of caries research, including the raise of the concept, the diagnostic standard, the problems and challenges facing, the interference and the treatment effect assessments of early stage subclinical caries. The prospect of the research is discussed as well to enhance the level of awareness and diagnosis and interference capability.

As a new technique, photedynamic therapy was introduced in the end of 1970s and has been put into clinical application from experimental tests in recent years. Its mechanisms was established on the basis that a series of special typed cells and tissues could selectively absorb photosensitive drugs and generate photore-sponsive effects by light irradiation of definite wavelengths. Currently, the photodynamic theraputics is applied mainly in non surgical treatment of tumor betided in body superfacial and hollow viscus. Its application area has been expanded unceasingly in modern clinic due to the discovery of the selective aggregation of photoresponsive drugs to many pathological tissues and pathogenic microorganisms other than tumors, and the development of new photoresensitizer. In this paper, review is given on the effect mechanisms, the light sources and photosensitizer, as well as the application of photodynamic treatment of tumors in head and neck and its treatments of mucosal dis-ease and oral pathogenic microorganism infected diseases.

Rheumatoid arthritis ( RA) is a kind of autoimmune disease with high morbidity characterized in synovitis.It has become a key goal for achieving an early RA remission.It is very important for application of RA remission normatively in the treatment of RA.In this paper, comparison and application of various RA remission criteria were reviewed, such as American College of Rheu-matology (ACR), European League Against Rheumatism (EULAR), US Food and Drug Administration (FDA), Outcome Measures in Rheumatoid Arthritis Clinical Trials ( OMERACT) group, ACR /EULAR remission criteria, etc.

Splice variants are transcripts that exhibit various functions or activities and are obtained from alternative splicing of precursor mRNA. An increasing number of tumor-specific splice variants are being discovered and their roles in cancer development and progression are being investigated. In this study, the expression patterns and activities of tumor-specific splice variants were charac-terized. The results suggest that a variant-specific gene therapy that targets cancer cells would be more specific and would have minimal effect on healthy tissues. Using antisense oligonucleotides, mRNA that contributed to cancer cell survival and altered splicing patterns was downregulated in a clinical trial. The results provide a new appreciation for the gene therapy of cancer. Identification of novel tu-mor-specific splice variants and constant improvement of therapeutic strategies by modifying splicing patterns can lead to the develop-ment of more effective and safer cancer therapies.

Prader-Willi syndrome is a rare genetic disorder characterized by hypotonia,poor feeding in infancy,hyperphagia with evolving obesity,hypogonadism,decreased adult height,and cognitive and behavioral disabilities.Recombinant human growth hormone (rhGH) has been used in treating Prader-Willi syndrome,and it has achieved good results.Several aspects still need to be concerned,including evaluation before rhGH treatment,age at treatment initiation,dosing,monitoring of potential side effects,tolerability,endpoint,response evaluation,use of adjunct therapies,and issues of consent.

The etiology of peripheral precocious puberty(PPP) is complex and varied,which is mainly categorized into either genetic or acquired disorders.Albright-McCune syndrome and familial male-limited precocious puberty are the 2 most important genetic PPPs.The purposes of therapy are to halt pubertal development and restore sex steroids to prepubertal values and delayed rate of skeletal maturation in order to maximize height potential.The several major categories of clinical drugs for PPP include anti estrogen/androgen,estrogen receptor blocker,aromatase inhibitors and cytochrome P450 inhibitors and so on.

Objective] To study the Xin'an doctor Sun Yikui Sun Wenyuan basis four diarrhea cases, in order to reveal Sun Yikui diarrhea syndrome differentiation syndromes characteristics. [Method] With Sun Wenyuan basis of diarrhea four proven cases as example, the combination of Neijing, Treatise on Febrile Disease, the Synopsis, Mingmen theory, Danxi academic ideas and related works and academic thoughts of Sun's, interpretation of Sun's diarrhea cases, comprehensive analysis of the syndrome differentiation syndromes characteristics. [Results] From the Sun Wenyuan basis diarrhea in four cases to know Sun Yikui grasp of vital theories and Danxi academic thoughts, clinical cure, the doer phlegmy wet, dyspepsia, the accountability of virtual are of pixu(deficient spleen), kidney deficiency, with particular emphasis on the pathological factors of kidney Yang deficiency, the author was good at using insurance and pills, Erchen Decoction, Benefit-stomach Shengyang Moisture-penetration soup, Liujunzi Decoction and revised prescriptions. [Conclusion] Sun Wenyuan basis contained diarrhea basis, Sun's clinically curing diarrhea with outstanding characteristics, the curative effect is distinct, we should combine classical and Sun's works to conduct the thorough research to the related basis, broaden the clinical cure drainage, help to improve the ability of clinical treating diarrhea.

HL7 is a widely-applied international standard for medical information exchange. With a HL7 data interface applied to a mainstream fully automatic biochemical instrument, this paper implements the information exchange between biochemical instruments and LIS following HL7 standard. This paper can be referred to when HL7 applied in other instruments.

Nuclear factor-?appa B(NF-?B) is an important transcription factor in the expression of any inflammatory media.The role of NF-?B in rheumatoid arthritis has been thought high recently.This review presents the role of NF-?B in rheumatoid arthritis,and the research progression of intervention therapy in inhibition of the activation of NF-?B is also introduced.

Janus kinase-signal transduction and transcription activator (JAK-STAT), mitogen- activated protein kinase (MAPK) and nuclear factor ?B (NF-?B) are three important cellular signalling pathways, which play pivotal roles in regulation of cellular physiologic as well as pathophysiologic functions. Based on the elucidation of the research progress of three signalling cascades, respectively, the current review focuses on the cross-talk of these signalling transduction, and the up-to-date details are also presented on their regulation in inflammatory response.
