1.Therapeutic effect of ellagic acid on Candida albicans infect mice models and its antifungal activity in vitro
Chinese Pharmacological Bulletin 2016;32(3):399-402,403
Aim To investigate the inhibitory effect of ellagic acid( EA) on fungal strains both in vitro and in vivo. Methods The minimal inhibitory concentration ( MIC ) was determined by the NCCLS ( M27-A2 ) standard method in vitro. The therapeutic action was studied using a Candida albicans infect mice model, the survival rate and the content of SOD, MDA in ser-um were measured, and the pathological changes of liver were observed under light microscope after HE staining. Results EA was active against three Candida strains, with MICs between 25. 0 and 75. 0 mg·L-1 . The most sensitive Candida species was C. albicans ( MIC=25. 0 mg·L-1 ) . It was inactive against Can-dida glabrata. An in vivo test demonstrated that intrap-eritoneal injection of EA(40 and 80 mg·kg-1 ) signif-icantly enhanced the pathological changes of liver, im-proved the symptom, increased the weight and the SOD activity, and decreased the MDA activity in a mice in-fection model of C. albicans. Conclusion Ellagic acid has the potential to be developed as a natural antifungal agent.
2.Breakdown of health resources efficiency and analysis of inter-provincial differences in China
Chinese Journal of Hospital Administration 2011;27(5):321-324
Objective To analyze the inter-provincial utilization efficiency of health resources and master the differences between these regions so as to rationalize the allocation of such resources.Methods This paper called into play the data envelopment analysis to survey the efficiency of interprovincial health resourcas utilization,and the Malmquist productivity index method for further breakdown of the total factor productivity.Results Years 2003 to 2008 averaged an yearly growth of 6.8% for the total factor productivity of health resources in 31 provinces;the rate of technological progress was positive,while the annual rate averaged 5.2%;a slight growth of technical efficiency at the growth rate of 1.5%.Conclusion Years 2003 to 2008 saw an increase of varying extent in the total factor productivity,yet an insufficient utilization of health technology in the provinces in general.Compared to the efficiency of the central provinces,low efficiency was found in both the eastern and western regions in China.The westem regions made a faster progress in technology utilization,thus narrowing the gap of health resources among the provinces.
3.Association between polymorphism of X-ray repair cross-complementing group 1 gene and radiation induced injury
Journal of International Oncology 2011;38(2):105-108
X-ray repair cross-complementing group 1 gene ( XRCC1 ) serves as one key DNA repair gene. The polymorphism of XRCC1, resulting in the changes of corresponding amino acid and the effect of DNA repair, may contribute to the radiation injury of malignant tumor patients. Current studies have revealed that single nucleotide polymorphisms of XRCC1 may be involved in the radiation injury for patients with tumor. Nevertheless this correlation remains to be further investigated.

ObjectivetTo investigate the interleukin-16 (IL-16) mRNA expression and IL-16 secretion by peripheral blood mononucle-ar cells (PBMCs) of patients with lupus nephritis (LN) .Methods: 15 patients with active LN, 10 with inactive LN and 8 normal controls were included in the research. TTie supernatant IL-16 levels of freshly isolated PBMCs were measured by ELISA; the IL-16mRNA level were measured by RT-PCR.Results: As compared with the control group, both active and inactive LN patients had significantly increase in IL-16mRNA expression and IL-16 secretion, but didn't find the difference of IL-16mRNA expression between active and inactive LN groups.Conclusion: LN patients can endogeneous over-express IL-16 gene and abnormally produce IL-16 protein by PBMCs . IL-16 might play a role in the patho-genesis of LN.

Objective To explore derivation of renocortieal prostaglandins in C-BSA nephritis. Methods The interfering effect of goat-antiplatelet IgG serum(APS)on this model was studied. Results The levels of renocortical PGE_2、6-keto-PGF_(1?) (PGI_2)、TXA_2 were all reduced in experimental group. The pathological damage of experimental group were less severe in comparison with the model group. Proteinuria of the experimental group was alleviated. Conclusion Platelet may play a pathogenetic role of C-BSA nephritis and renocortical prostaglandins partly derive from platelets.

The role of consolidating radiation therapy (RT) is very controversial in Hodgkin lymphoma (HL),especially in adolescents and young adults (AYA) HL.The key problem is how to achieve better therapeutic effect but bear less toxicities in chemotherapy and radiotherapy,which will be hopefully solved by clinical trials adopting interim positron emission tomography (iPET) scanning to guide therapy for HL.The new technologies including whole genome amplification (WGA),high-throughput gene sequencing (NGS) assay and genome-wide association study (GWAS) further illustrate abnormal signaling pathways in HL,such as NF-κB,JAK/STAT and PI3K pathway,which may provide new therapeutic targets for the disease.

Objective To reconstruct caudate nucleus,lentiform nucleus and thalamus three-dimensionally,fuse these neural structures with (patient's) radiological images and provide anatomical data for diagnosis and treatment of neurosurgical diseases. Methods Chinese Virtual Human dataset was segmented using image-transparency method at first and each image was smoothed by eroding and dilating, then fused neural structures with MRI,the neural structures and brain in MRI were reconstructed and displayed using surface rendering and volume rendering lastly. Results The reconstructed neural structures were smooth,natural and realistic.Their shapes and positions was clearly displayed and could be rotated, observed in any direction.On the fused images,the neural structures and tumor could be seen at the same time.Conclusion The reconstructed structures and fused images have great reference value to teaching and learning and diagnosis and treatment of neurosurgical diseases.

Objective To explore the relationship between chronic severe hepatitis and cryptosporidium infection to provide evidences for scientific prevention and treatment of chronic severe hepatitis. Methods Fecal samples of 218 patients with chronic severe hepatitis B (CSHB) and 140 children with diarrhea were collected, and were examined for cryptosporidium oocytes by using auramine-phenol staining method (AA-p) and modified acid-fast staining method (MAF), and for cryptosporidium DNA by PCR and restriction digestion analysis. The factors affecting cryptosporidium infection of patients with CSHB were preliminarily analyzed. Results The positive rates of cryptosporidium infection detected by AA-p, MAF and PCR in the patients with CSHB and children with diarrhea were 4.1%, 3.2%, 6.0% and 0.7%, 0.7%, 1.4%, respectively. The positive rate of cryptosporidium infection detected by PCR in patients with CSHB was higher than that in children with diarrhea (P
