This paper made some reflections on the development of traditional Chinese medicine(TCM) nephrology in recent years. It analyzed the strategic position and importance of social development in the field of prevention and treatment of diseases by TCM. Problems and puzzles on this subject had been summarized and countermeasures had been put forward. Preliminary conceptions on development strategies, goals and direction of TCM nephrology had been made.

Liver fibrosis can be classified as a wound-healing response to a variety of chronic stimuli,and is characterized by an excessive deposition of extracellular matrix(ECM)proteins.Hepatic stellate cells(HSCs)are presently regarded as one of the key cell types involved in the progression of liver fibrosis.Following a fibrogenic stimulus,HSC changes from a quiescent to an activated,collagen-producing cell.Each cellular response to extracelluar stimuli must be framed in a scenario.Along these lines,the identification and characterization of intracellular signaling pathways activated by different stimuli in HSCs represent a mandatory step.Drug targets which aim at the extra-cellular signals or intra-cellular cascades are required for ameliorating liver fibrosis.

Hepatic fibrosis is a pathological process in which excessive deposition of extracellular matrix components, occurs due to an imbalance between the production and degradation of matrix. Fibrosis is the hallmark of most chronic liver diseases. It is also the major factor of the development of chronic hepatitis and cirrhosis. Therefore, in light of the regulative factors on different levels and mechanism of fiber synthesis and degradation, antifibrotic medicine can inhibit the synthesis of matrix or increase its degradation on different links. The present situation concerning the study of the therapeutic effect of traditional Chinese medicine and natural medicine on hepatic fibrosis is reviewed.

Based on the "Grayscales average distribution" method which equally distributes the input gray levels to output gray levels, three improved methods named: "Reduce the gray range expressed by the less significant subfields", "Low levels preset" and "Modify the exponent of inverse-gamma function" are proposed in this paper. Using these methods, the inverse-gamma relation subfields code can be obtained easily which can improve the low level expressions of AC-PDP. And a program, "gray scales distribution validate program", which can enhance the expressions of the demanded gray levels range, is also proposed in this paper.

Objective: To explore the relationship between CDR1 and CDR2 expression and fluconazole-resistance in clinical Candida albicans strains, so as to explore the mechanism of drug-resistance in Candida albicans. Methods: The minimal inhibitory concentrations (MICs) of clinical Candida albicans strains to fluconazole were determined by broth microdilution method. The total RNA of fluconazole-susceptible and fluconazole-resistant Candida albicans strains were extracted, and the expression of the CDR1 and CDR2 genes was examined by real-time RT-PCR. The efflux of Rhodamine 6G was determined in the strains highly expressing CDR1 and CDR2 genes. Results: The incidences of CDR1 and (or) CDR2 overexpression in fluconazole-resistant strains were significantly higher than those in the fluconazole-sensitive stains. The efflux of Rhodamine 6G was significantly increased in the fluconazole-resistant strains when glucose was added, and overexpression of CDR1 and CDR2 were observed in theses strains. Some resistant strains showed no overexpression of CDR1 and CDR2. Conclusion: Fluconazole-resistance in clinical Candida albicans strains is related to the overexpression of ABC transporter proteins. Overexpression of ABC transporters can increase the efflux of drugs and therefore lead to drug-resistance. Other mechanisms may also participate in the development of drug resistance in the clinical Candida albicans strains.

Unmethylated CpG motif containing oligodeoxynucleotide(CpG ODN) can induce secretion of dendritic cells,and thus presents antigens efficiently,increases expression of costimulatory molecules,causes innate immunity response and adaptive immunity response,then plays anti-tumor roles.

A Review] The neuroendocrine-immunoregulatory network is fundamental to the maintenance of homeostasis. In this article, the authors present an overview of the role of neuroimmunoregulatory mechanism in the occurance and development of some diseases, which may have important therapeutic implication for the clinics.

Objective To observe the effects of minimally traumatic puncture drainage of hematoma combined with Salviae Miltiorrhizae injection(丹参注射液) on the edematous volume around the lesion and neural functional defect in patients with hypertensive cerebral hemorrhage.Methods Eighty-nine patients with hypertensive cerebral hemorrhage were randomly divided into two groups: treatment group(n=45) and control group(n=44).All the patients had received minimally traumatic puncture drainage of hematoma,dehydration therapy,hemostatics,anti-inflammatory and anti-hypertensive agents, etc.In addition,Salviae Miltiorrhizae injection was continuously injected intravenously in the patients in the treatment group for three weeks.Cranial CT was performed to measure the volume of edema around the lesion at 7,14 and 21 days before and after operation,neurologic impairment degree scores(NDS) were assessed by National Institutes of Health Stroke Scale(NIHSS),and at the same time the fatality rate and re-hemorrhagic situation were observed at 14 and 30 days before and after initiating the operation.Results The areas of perilesional edema in both groups were conspicuously diminished at 7,14 and 21 days after initiating the operation,the area of perilesional edema diminished gradually,and significantly smaller in the therapeutic group than that in the control group at 14 and 21 days(P
