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.

Objective To establish the reference intervals of thyroid hormone levels fro the women in early ,middle and late preg‐nancy in the local area .Methods Through the strict screening for routine diagnosis of pregnant women who went to the hospital , we choose 420 women with 6-37 weeks of pregnancy and 120 non pregnancy women(control group) .Chemiluminescence was used to detect thyroid stimulating hormone(TSH) ,free thyroxine(FT4 ) ,total thyroxine(TT4 ) ,free triiodothyronine(FT3) ,total triiodo‐thyronine(TT3 ) for the pregnant women in early pregnancy(0-12 weeks) ,mid‐pregnancy(13-27 weeks) ,and late pregnancy(28-40 weeks) and women in control group .Using those data ,we established reference intervals of thyroid hormone and use bilateral limits P2 .5 - P97 .5 to represent .Results The differences of serum TSH ,FT4 ,TT4 ,TT3 concentration between pregnant group and control group were statistically significant(P<0 .05);while the difference of serum FT3 concentration between pregnant group and control group was not statistically significant(P=0 .79) .The concentration of TSH was not statistically significantly different in the mid‐pregnancy compared with late pregnancy(P=0 .933) ,the reference interval can be merged as 0 .56-3 .94μIU/mL .Conclu‐sion The establishment of normal reference interval of thyroid hormone concentration in different period of pregnancy respectively is conducive to the diagnosis and treatment of thyroid disease in pregnancy .

Fifty-two cases of acute leukemia were treated with chemotherapy, and forty-one cases in combination vrith Spirulina platensis. After the therapy, the patient's bone marrow was inhibited. The inhibition period of bone marrow was shortened and the recovery period was advanced in the combined Spirylina platensis therapy, the level of peripheral blood cells was raised. The results suggest that the combined spirulina platensis therapy in chemotherapy could accelerate the recovery of the normal hematopoiesis and increase the amounts of blood cells.
