Study the serum level of HGF, Cys C and TGF-beta1 in type 2 diabetic nephropathy (DN), the infect of Pingshen decoction on those index. Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.

Objective To investigate the expression and significance of the endocrine gland-derived vascular endothelial growth factor (EG-VEGF) and vascular endothelial growth factor(VEGF) in adrenocortical lesions of primary aldosteronism. Methods The expressions of EG-VEGF, and VEGF were detected by immunohistochemistry and real-time fluorescence quantitative PCR in samples of 18 cases of adrenocortical adenoma, 6 adrenocortical hyperplasia, and 8 normal adrenal cortex. The correlation between the expressions of EG-VEGF, VEGF, and clinicopathological parameters was analyzed. Results The expression of EG-VEGF or VEGF in adrenocortical adenomas was higher than that in adrenocortical hyperplasia or normal adrenal cortex ( all P＜0. 05 ), and the expression of EG-VEGF or VEGF between adrenocortical hyperplasia samples and normal adrenal cortex samples was indistinctive. There was no statistically significant correlation between EG-VEGF or VEGF expression and sex, age, blood pressure, serum potassium, plasma renin activity, except in case of serum aldosterone( P＜0.05 ). A positive correlation between EG-VEGF and VEGF ( P＜0. 01 ) was found. Conclusions EG-VEGF and VEGF may play a significant role in the formation and development of adrenocortical tumors in primary aldosteronism.

The expressions of Ki67 and FHIT were detected by immunohistochemical staining in 15 cases of adrenocortical carcinoma, 42 cases with adrenocortical adenoma,6 cases of adrenocortical hyperplasia, and 10 cases of normal adrenocortical tissue. The results showed that the highest expression of Ki67 and the lowest expression of FHIT were found in adrenocortical carcinoma. There were significant differences in the Ki67 and FHIT between adrenocortical adenoma and adrenocortical carcinoma ( both P < 0. 05 ). There existed negative correlation between the expressions of Ki67 and FHIT( r=-0. 712, P<0.05 ). Ki67 over-expression and loss of FHIT expression may be involved in the occurrence and development of adrenocortical carcinoma. It is suggested that combined detections of Ki67 and FHIT may have reference significance in the differentiation of adrenocortical adenoma from adrenocortical carcinoma.

The shape and structure of granules are controlled by the granulation process, which is one of the main factors to determine the nature of the solid dosage forms. In this article, three kinds of granules of a traditional Chinese medicine for improving appetite and promoting digestion, namely, Jianwei Granules, were prepared using granulation technologies as pendular granulation, high speed stirring granulation, and fluidized bed granulation and the powder properties of them were investigated. Meanwhile, synchrotron radiation X-ray computed micro tomography (SR-µCT) was applied to quantitatively determine the irregular internal structures of the granules. The three-dimensional (3D) structure models were obtained by 3D reconstruction, which were more accurately to characterize the three-dimensional structures of the particles through the quantitative data. The models were also used to quantitatively compare the structural differences of granules prepared by different granulation processes with the same formula, so as to characterize how the production process plays a role in the pharmaceutical behaviors of the granules. To focus on the irregularity of the particle structure, the box counting method was used to calculate the fractal dimensions of the granules. The results showed that the fractal dimension is more sensitive to reflect the minor differences in the structure features than the conventional parameters, and capable to specifically distinct granules in structure. It is proved that the fractal dimension could quantitatively characterize the structural information of irregular granules. It is the first time suggested by our research that the fractal dimension difference (Df,c) between two fractal dimension parameters, namely, the volume matrix fractal dimension and the surface matrix fractal dimension, is a new index to characterize granules with irregular structures and evaluate the effects of production processes on the structures of granules as a new indicator for the granulating process control and optimization.

According to the designed specific primers of gene fragment based on the Salvia miltiorrhiza transcriptome data, with the method of reverse transcription polymerase chain reaction (RT-PCR), this study cloned full-length cDNA sequence of 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate synthase gene from Salvia miltiorrhiza bge.f.alba, this sequence is named as SmHDS and its GenBank registration number is KJ746807. SmHDS, 2 529 bp long, contains an ORF of 2 229 bp, encodes 742 amino acids, including 5' UTR 170 bp and 3' UTR 130 bp. Using bioinformatics software, having made a homology analysis of the obtained sequence, we can have a conclusion that SmHDS have a close genetic relationship with HDS of Salvia miltiorrhiza. Analysis result of prokaryotic expression revealed that in Escherichia coli, SmHDS expressed target proteins which in size are comparable with the protein predicted. Meanwhile, the 4 factors which can influence the protein expression were optimized, the 4 factors are inducing temperature, inducing time, IPTG concentrations and density of inducing host bacterium (A600). The optimal expression conditions of SmHDS were 30 degrees C until the A600 is 0.6, and add IPTG to a final concentration of 0.2 mmol x L(-1), and the induction time of 20 h. It provides theoretical basis for the further study of the function of 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate synthase in the biosynthesis of tanshinone compounds.

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal disorder of hematopoiesis due to the inactivation of PIG-A gene. However, the presence of mutant PIG-A gene in a group of hematopoietic cells is not enough for the development of PNH, immunologic injury and apoptotic effects are considered to play an important role in clonal expansion. Knowledge of the molecular mechanisms leading to PNH has substantially increased in the past decades, which remarkably advances the diagnostic modalities and treatment approaches of patients with PNH. Though great progress has been made because of targeted therapy method, the challenges are still ahead. In this review the advances of studies on mechanism, laboratorial diagnosis and therapeutic protocols of PNH are summarized.

OBJECTIVETo study the main factors influencing prognosis of hemophagocytic lymphohistiocytosis (HLH) in children by summarizing the clinical features of HLH and investigating the relationship between relevant factors and prognosis.

METHODSThe medical data of 63 children with HLH were retrospectively reviewed. Kaplan-Meier method was employed to draw survival curves. Factors influencing prognosis were assessed with Cox univariate analysis, and Cox multivariate analysis was done on statistically significant factors.

RESULTSThe 3-year and 5-year survival rates were both 62.9%. The survival rate decreased from 98.4% at 1 day after definite diagnosis to 73.2% at 4 months. Univariate analysis demonstrated only one factor, which was that the condition of platelet recovery after treatment of 2 to 3 weeks was significantly related to prognosis (P=0.002). In children receiving etoposide therapy, temperature recovery after one day of treatment was significantly related to prognosis (P=0.016).

CONCLUSIONSChildren with HLH have a satisfactory prognosis, but the survival rate reduces rapidly in the first 4 months after definite diagnosis. Platelet recovery after treatment of 2 to 3 weeks and temperature recovery after one day of treatment are factors influencing prognosis of HLH in children.

Objective To observe the state of endemic flurosis, construction and running status of water improvement projects in order to provide a scientific basis for prevention and treatment fluorosis. Methods Water samples of the diseased and nondiseased villeges were collected from east, west, south, north and centre of each villege in 2005, and fluoride concentration was determined for each surveyed village with unimproved-water. At the same time, all the tap water and source water samples were collected to determine fluoride concentration in each water-improved village surveyed. In 2008, all the endemic fluorosis villages in Guied county were divided into slight, medium and heavy types according to the water fluoride content before water improved, and 1,1,3 survey villages were chosen from each type. In all of the village children aged 8 to 12 years were tested for dental fluorosis by Dean method. Six copies of the urinary fluoride were sampled in different age groups. The fluorine content in water and urine was determined by F-ion selective electrode. The situation of clinical skeletal fluorosis of adults over 16 years of age was investigated, 20 adults (evenly divided between men and women) in the villages of medium and heavy types were examined by X-ray for skeletal fluorosis. Results In 3 village fluoride content of drinking water exceeded the national drinking water standards ( <1.0 mg/L) of 85 surveyed villages with improved-water. Among the 16 projects, 8 were intermittently running and 3 were retired, leaving only 31.25% of the projects active. Theprevalence of enamel fluorosis was 41.13%( 116/282), that of skeletal flurosis was 47.95%(969/2021) and that of X-ray checked was 20.73% (17/82). The median of urine fluoride was 1.06 mg/L and the scope was 0.20 - 9.44 mg/L.Conclusions Most of the improved-water projects do not normally supply water in the disease ward of Guide county. Therefore, there is an increasing trend of the disease, so further control measures are needed.
