Objective:To analyze the effects of essential medicine system on revenue structures at primary med-ical institutions. Methods:Data on revenue status and structures from 58 township health centers in Shanxi Province was collected to analyze changes and trends. Results:Along with growing government investments in primary medical institutions, the essential medicine system has fundamentally realized full coverage. The percentage of essential medi-cine revenue to pharmaceutical revenue rose from 20 . 45% in 2009 to 97 . 03% in 2013 , though the percentage of pharmaceutical revenue to total revenue dropped by 18 . 43%. The percentage of fiscal subsidy revenue in total reve-nue rose from 25 . 77% in 2009 to 54 . 16% in 2013 , though the percentage of business revenue to total revenue dropped in general. Conclusions:The essential medicine system requires the government’s financial support. Essen-tial medicine lists and primary financial aid policies should be further improved;doctor reimbursement and incentive mechanisms should be improved as well and unreasonable doctor service pricing and reimbursement mechanisms should be reformed.

OBJECTIVETo investigate the expression of protein tyrosine phosphatase non-receptor type 2 (PTPN2) and nuclear factor-kappaB (NF-kappaB), as well as the relationship between their expression and periodontal destruction in mice with diabetic periodontitis.

METHODSFour weeks old healthy C57BL/6J mice were randomly divided into normal control group (Group N), periodontitis group (Group P) and diabetic periodontitis group (Group DP), and each group had six mice. Mice in Group P were inoculated Porphyromonas gingivalis orally to induce periodontitis. Mice in Group DP had high sugary and fatty food, streptozotocin intraperitoneal injection and Porphyromonas gingivalis oral inoculation to induce diabetic periodontitis. All mice were sacrificed 4 weeks after the last bacterium inoculation of Groups P and DP. Stereo microscope was chosen to detect morphological changes and bone loss areas of the alveolar bone. Hematoxylin-eosin (HE) staining was selected to observe loss heights of periodontal attachment. Immunohistochemical staining was used to detect PTPN2 and NF-kappaB expression in periodontal tissues.

RESULTSGroup P and Group DP had significantly more attachment loss heights and areas than Group N (P < 0.05), and showed less PTPN2 expression (P < 0.05) and higher NF-kappaB levels (P < 0.01).

CONCLUSIONPTPN2 may negatively regulate the development of diabetic periodontitis, while NF-kappaB may have opposite effects. PTPN2 down-regulation might contribute to NF-kappaB over-expression leading to exacerbated periodontal destruction.

beta-CIT was labeled with 131I by the peracetic acid method. Cat model of Parkinsonism was set up with MPTP. Each of normal and PD model cats was given an injection of 74 MBq/0.5 ml 131I-beta-CIT into the femur vein. Then the blood samples were obtained at 4 h and 20 h, the radioactivity was counted with calibrator. The biodistribution data of 131I-beta-CIT in cat body was calculated (ID%/g). The cats were subjected to imaging at 0.5 h, 1 h, 2 h, 4 h, 20 h after the administration of radiopharmaceutical. The radioactivity in striatum and cerebellum was measured and striatal specific binding ratios were calculated. The Results showed that the radio chemical purity of 131I-beta-CIT was 97.62% +/- 0.31%. The 131I-beta-CIT remained stable for at least 4 h after incubation with water and serum respectively. Following intravenous administration in cats, 131I-beta-CIT showed high accumulation in striatum. The study of imaging in cats showed that striatal specific uptake of 131I-beta-CIT at 20 h after injection was 4.83 +/- 0.82 in normal cats and 2.92 +/- 0.66 in PD cats. There was a significant reduction of striatal tracer uptake in PD cats, compared to the controls. The results of biodistribution study was in agreement with the results of imaging study. These results suggest that beta-CIT is an ideal agent for dopamine transporter imaging and can be used for the diagnosis of Parkinson's disease.

The complete coding sequences of Eya gene family was amplified by standard PCR fromhuman tissues or cells cDNA library.The product of PCR was cloned into the eukaryotic expression vector pcDNA3-FLAG,generating pcDNA3-FLAG-Eya1～4.Thenhuman embryo kidney 293T cells were transfected with the recombinant plasmids and the expression of Eya genes were identified by Western blot.Transcriptional assay using a reporter containing myogenin enhance factor indicated that expression of Eya cooperation with Six in 293T cells affected the Myogenin gene expression.The expression vectors of Eya genes were constructed and confirmed by restriction enzyme digestion and DNA sequence analysis.Transcriptional assay using a reporter containing myogenin enhance factor indicated that expression of Eya in coordination with Six in 293T cells stimulated the Myogenin gene expression.Eya proteins are transcriptional activator of Six and can improve the activity of myogenin promoter.

Objective To investigate the protective effect of erythropoietin(EPO)on the mitochondria in the brain neurons against cerebral ischemia/reperfusion(IR)injury in rats.Methods Thirty SD rats are randomly allocated into 3 groups,namely the EPO group(n=10),IR group(n=10),and shamoperation group(n=10).In EPO group and IR group,the rats were subjected to middle cerebral artery occlusion(MCAO)to induce cerebral IR injury,followed by treatment with intraperitonal EPO injection at 3000 U/kg and the same volume of saline,respectively.In the sham operation group,the carofid artery was only isolated without MCAO or subsequent treatment.Seventy-two hours after the IR injury,the mitochondrial membrane potential in the neurons was detected,and the changes in superoxide kismutase(SOD)activity,malondialdehyde(MDA)and nitric oxide(NO)concentrations,and Na+-K+-ATPase activity in the neuronal mitochondria were determined.The number of caspase-3-positive neurons in the hippocampus Was observed immunohistochemically. Results The mitochondrial membrane potential and activities of SOD and Na+-K+-ATPase Were significantly higher.whereas the MDA and NO concentrations and the number of caspase-3-postive neurons significantly lower in EPO group than in IR group after the treatment.Conclusion Protecting the neuronal mitochondrial function is one of the important mechanisms of EPO for brain protection against IR injury,and this mitochondrial protection effect is mediated essentially by stabilizing the mitochondrial membrane potential.

OBJECTIVETesticular mixed nonseminomatous germ cell cancer (TMNGCC) is rarely reported. This study aimed to explore the clinical symptoms, pathological characteristics and treatment methods of TMNGCC.

METHODSWe analyzed the clinical data of 1 case of TMNGCC, observed its pathological characteristics under the light microscope by histology, cytochemistry, immunohistochemistry and immune marking, and investigated the clinical features of such tumors by reviewing the relevant literature.

RESULTSThe patient presented with a chief complaint of painless testicular swelling for 3 years. Histopathological examinations revealed a tumor of papillary, fissural or adenoid structure, with large polygonal or columnar cells with one or more irregular vesicular nuclei, the nuclear membrane clear, the cytoplasm eosinophilic or basophilic, and the interstitium infiltrated by a few lymphocytes. Here are the immunohistochemical results: CD117 -, CK8-18 + +, CD30 + +, CK + + +, vimentin -, PLAP +/-, P53 +, AFP + and EMA + +. The tumor was pathologically diagnosed as teratogenic embryonic testicular cancer, and treated by radical surgery, followed by adjuvant chemotherapy according to the treatment of TMNGCC. One-year follow-up found the patient to be alive.

CONCLUSIONTMNGCC is a rare malignant tumor, mostly with unobvious clinical symptoms. Its diagnosis primarily depends on physical examination, ultrasonography, CT, and measurement of serum tumor markers; its confirmation necessitates pathological examination, and its first-choice treatment is surgical resection.
