The informatization of traditional Chinese medicine resources is the basis of modern medicine. With a spatial attribute traditional Chinese medicine resources could be carried out for in-depth spatial analysis, data mining and traditional Chinese medicine resources regional industrial layout. In this paper, we took the data of Glycyrrhiza uralensis in the third national Chinese medicine resources survey as the experimental data, described the principles and structure of traditional Chinese medicine resources spatial information database. We also described the establishment of analysis model with the help of this spatial database.

OBJECTIVETo study the effect of Angelica sinensis, Salvia miltiorrhiza and Ligustrazine on function of peritoneal macrophages during peritoneal dialysis.
METHODSPeritoneal macrophages of mice were cultured in culture medium (control), peritoneal dialysate (PD), drugs contained PD containing Angelica, Salvia and Ligustrazine combined (PD-ASL) or separated (PD-A, PD-S, PD-L) with concentration of 2 micrograms/ml, 10 micrograms/ml and 100 micrograms/ml, separately for 24 hrs. The nitric oxide (NO) content, methyl thiazolyl tetrazolium (MTT) reducing capacity (MTT-RC) and phagocytosis capacity of macrophages were determined and compared.
RESULTSNO content and MTT-RC of macrophages cultured in PD group were significantly lower than those of the control (P < 0.01), as compared with those in drug contained PD groups, the NO content in the PD-L group and the MTT-RC in the PD-ASL group were higher significantly (P < 0.01). The phagocytosis capacity and NO content in the PD-ASL group were raised along with the increased concentration of drug in PD.
CONCLUSIONAdministering Chinese herbal medicine during peritoneal dialysis has important significance in improving the defense function of peritoneal macrophages, reducing the incidence of peritonitis and enhancing the therapeutic effect of peritoneal dialysis.

Objective To investigate the methylation status in the promoter region of Dickkopf-3 (Dkk3) gene in patients with myelodysplastic syndromes (MDS),and to initially explore the relationship between the methylation of this gene and survival time.Methods Methylation-specific PCR (MSP) was applied to measure the promoter methylation of Dkk3 gene in 43 bone marrow or peripheral blood samples of MDS patients.As controls,70 normal peripheral blood samples from general outpatients were examined.Results In 43 patients with MDS,7 patients (16.3 %) showed Dkk3 gene methylation.And 5 of them were semi-methylation status,2 of them were exhaustive methylation status.In 70 controls,1 showed Dkk3 gene semi-methylation.The frequency of methylation in MDS patients was significantly higher than that of controls (x2 =8.93,P =0.005).In the Dkk3 methylation group,2/7 were from bone marrow and 5/7 were from peripheral blood.Meanwhile,2 patients were RA,1 patient was RCMD,4 patients were RAEB.There was no significant difference between the different sample source (bone marrow or peripheral blood) for the results of the methylation status (x2 =0.051,P =0.821).Either between the different sex,age,type,chromosome and WPSS score (P > 0.05).The progress of disease didn't influence the methylation frequency (P > 0.05).The smvival analysis showed no relationship between the methylation of this gene and smvival time.Conclusions In this MDS group,there is high level of methyl-modification in Dkk3 gene.The methylation of Dkk3 might be one of the molecular mechanisms that contribute to the progress of patients with MDS.The peripheral blood sample maybe a better substitute in detective of Dkk3 with MDS.

Abstract: At present, nucleic acid detection technology based on the PCR principle is commonly used to detect malaria parasites, the existing Plasmodium detection methods mainly include microscopy, antigen immunoassay, and nucleic acid detection,but due to the long detection time, high personnel and equipment requirements, and other shortcomings, its popularization, and application at the grassroots level are limited. What challenges previous Plasmodium detection methods are the lack of experienced professionals and advanced equipment at the grassroots as well as the requirement of rapid detection of large samples under extreme conditions. The isothermal amplification technology developed in recent years has potential application prospects due to its simplicity, rapidity, high sensitivity, and high specificity. This article attempts to review the principles, characteristics, and prospects of various isothermal amplification technologies, and on this basis, focuses on the introduction of recombinase polymerase amplification (RPA) and recombinase⁃aided isothermal amplification (RAA) assay technologies and proposes the use of such recombinant enzyme amplification technologies to achieve rapid and accurate diagnosis of common Plasmodium species possibility and imagination.

OBJECTIVETo investigate the relation between sinus-straddling hematoma (SSH) and venous sinus injury and explore the approaches for surgical management.
METHODSThirty-six cases of stride sinus hematoma were reviewed to observe the incidence rate of sinus injury complicated with (SSH) and explore its surgical management.
RESULTSThe incidence rate of venous sinus injury following (SSH) was 80.56% (29/36), and appropriate surgical management yielded good therapeutic effect in these patients.
CONCLUSIONIntracranial stride sinus hematoma is often accompanied by venous sinus injury, and adequate preoperative risk evaluation may improve the success rate of the operation.

This study aims to analyze and compare the effect of cell wall-broken decoction pieces, conventional decoction pieces and conventional powder of Rhodiolae Crenulatae Radix et Rhizoma on the intestinal flora of normal mice. The conventional bacterial culture and PCR-DGGE (polymerase chain reaction-denaturing gradient gel electrophoresis) were adopted for the mice after the oral administration for 14 days. According to the bacterial culture results, the 1/8 dose cell wall-broken decoction pieces group showed fewer Enterococcus and Escherichia coli bacillus but more Lactobacillus and Bifidobacterium than the conventional decoction pieces group and the traditional powder group (P <0.05). Meanwhile, on the basis of the PCR-DGGE results, the 1/8 dose cell wall-broken decoction pieces group revealed the highest Shannon-Wiener index (H) and species richness (S) among the seven groups, with extremely significant differences compared with the normal group (P <0.01), significant differences compared with the conventional decoction pieces group and the conventional powder group (P <0.05) and a high intra-group similarity. In conclusion, the long-term intake of 1/8 dose Rhodiolae Crenulatae Radix et Rhizoma cell wall-broken decoction pieces showed a certain effect in regulating intestinal tract by promoting the growth of Lactobacillus and Bifidobacterium. Furthermore, the intestinal flora community will become more stable.

Objective To study Epstein-Barr vires infection and p16 protein abnormal expresson in carcinogenesis and progression of gastric adenocarcinomas (GAC). Methods Immunohistochemical staining SP method was used to detect the expression of LMP-1 and p16 in 97 cases of GAC. Results EBV LMP-1 and p16 protein were detected in 30.9% (30/97) and in 63.91% (62/97) cases of gastric adenocarcinomas respectively.There was no significant difference between EBV-positive and EBV-negative gastric carcinomas in sex, histologic type, depth of tumor invision, lymph node metastasis and clinical stages (P>0.05);overexpression of p16 was associated with lymph node metastasis and clinical stages; no correlation was found between the expression of EBV LMP-1 and p16 protein. Conclusion ①EBV play a role in carcinogensis of GAC. ②P16 gene abnormality is frequently involved in GAC and might be one of the important prognostic factors. ③EBV infection and p16 alteration are two independent roles in GAC carcinogenesis.
