Objective In order to understand the mechanism of solute transperitoneal transport, we studied the relationship between IL-8 level and protein transperitoneal transport. Method 12 New Zealand White rabbits were randomly divided into experimental and control groups. 2 5% glucose peritoneal dialysis solution (40ml/kg)contained 3?10 9 CFU staphylococcus aureus 1ml was injected into the abdominal cavity of experimental NZW rabbits and 2 5% glucose peritoneal dialysis solution (40ml/kg)contained 0.9%NaCl solution 1ml was injected into the abdominal cavity of controlling NZW rabbits. The plasma and effluent concentrations of blood creatinine ,glucose,total proteins and albumine were determined respectively, the D/P or D/Do values of creatinine , total proteins ,albumine or glucose were calculated respectively. Results The D/P ratios of creatinine, total proteins and albumin were increased significantly, while the D/Do of glucose was decreased in experimental group on different dwelling time points ,there was a significantly difference,as compared with the control group (P0 05),while there was significantly correlation after 60 mins(P
4. Polymorphism and pharmacokinetic research of ribavirin
Chinese Pharmaceutical Journal 2013;48(8):621-628
OBJECTIVE: To establish the preparation method and detection technology of ribavirin polymorphism, and to estimate the bioavailability differences among the ribavirin polymorphs. METHODS: Through polymorphism screening, ribavirin crystals of the form A, B, C, D were obtained. The crystal forms of ribavirin were characterized by different analysis methods, such as single crystal X-ray diffraction method (SXRD), powder X-ray diffraction method (PXRD), differential scanning calorimetry method (DCS), infrared spectrum method (IR) and melting point method (MP). solid ribavirin in different forms were orally administered to rats, and an HPLC-MS method was established to determine the plasma levels of ribavirin, and the bioavailability was analyzed. RESULTS: Of the four polymorphs of ribavirin, form C and form D were reported for the first time. The four polymorphic forms all could be identified by PXRD, DSC, IR and MP. The ρmax and AUC0-t of form A were superior to those of the other forms. CONCLUSION: Characteristic data for ribavirin polymorphism are obtained; and form A of ribavirin is a suitable medicinal crystal. This study has provided the basis for choice of medicinal crystal and the improvement of quality standards.
5.Relevance of cancer toxin pathogenesis theory with transformation of inflammation to carcinoma.
Chinese Journal of Integrated Traditional and Western Medicine 2015;35(2):243-246
The "Cancer Toxin" pathogenesis theory is an innovate theoretical system for cancer pathogenesis of Chinese Medicine, which was built on the basis of "Cancer Toxin" concept initially raised by Professor ZHOU Zhong-ying. The mechanism of the transformation from inflammation to carcinoma has become one of hot-points in the field of cancer research at home and abroad in recent years. We focused on discussing the relevance of the "Cancer Toxin" pathogenesis theory with the transformation mechanism from inflammation to cancer, provided evidence for using "Cancer Toxin" pathogenesis theory in intervening transformation from inflammation to cancer, hoping to guide for Chinese medical prevention and treatment of tumor.

NDUFS3 is an essential subunit of mitochondrial NADH:ubiquinone oxidoreductase (complex Ⅰ ) and plays a critical role in the mitochondrial typeⅠ respiration chain.Mutations in this gene are shown to cause neurodegenerative disease such as Leigh syndrome (subacute necrotizing encephalopathy).In recent years,many evidences show that the expression of NDUFS3 proteins are lower in many cancerous cells compared to the corresponding normal cells.It comes to the conclusion that NDUFS3 may play a role in the tumorigenesis.

Thioredoxin-related protein 14 (TRP14),a new member of Trx family,is a novel disulfide reductase with conservative CPDC motif.Its structure and function are comparable to Trx,which is the representative member of Trx family.However,there are many differences.When tumor necrosis factor-α (TNF-α) induced cells to produce the active oxygen,TRP14 can change oxidatin state of dynein light chain(its substrate),act as a sensor of the intracellular redox state to regulate NF-κB signaling pathways induced by TNF-α,MAPK and apoptosis signaling pathways.

Hepatitis virus NAT reagents are now widely used clinically. However, the qulity of domestic and foreign NAT reagents varies dramatically. The main reasons for these differences including the manufacture technique, test principle and assay procedure were discussed in this paper and current status of the quality control of the NAT reagents were also described. Finally, it was pointed out that strengthening public supervision and laboratory internal control are very important for the quality improvement of the domestic reagents.

Objective To explore the relationship between serum placental growth factor (PLGF) and carotid atherosclerosis (CAS) in patients with type 2 diabetes mellitus (T2DM ). Methods Serum PLGF were determined by ELISA in 53 patients with T2DM ,who were divided into T2DM without carotid plague (T2DM group ,n= 27) and T2DM with carotid plague (T2DM + CAS group ,n= 26). Fasting plasma glucose (FPG) ,glycosylated hemoglobin A1c (HbA1c) and some other metabolic variables were also measured. The results were compared to those of 27 healthy controls (NC group). Results Serum PLGF levels were significantly higher in T2DM group and T2DM + CAS group than in NC group (P<0.01). T2DM+CAS group showed significantly higher serum levels of PLGF compared to that of T 2DM group(P<0.01).Correlation analysis showed that serum PLGF was positively correlated with TC ,LDL‐C , hsC‐RP and IL‐6 in T2DM patients (P<0.01). Similarly ,multiple regression analysis showed that LDL‐C and IL‐6 were the independent factors of serum PLGF level (P<0.05). Furthermore ,Serum PLGF was positively associated with carotid plague. Conclusion PLGF is positively related with chronic inflammation factors in T2DM patients. Serum PLGF may play an important role in the occurrence and development of carotid atherosclerosis and other macroangiopathy in T 2DM.
