In the health service field,health resources and health service supple capacity were related with the resource and capacity in economics.Health resources,health service supple capacity and their relationships were important factors for the cooperation and benign interaction of hierarchical medical institutions.However,inversion of health resources and health dislocation of service supply capacity exacerbated the agglomeration degree of patients in the tertiary medical institutions under the impact of residents' freely searching for medical service concept.Vicious interaction and mutual competition among hierarchical medical institutions had become an important obstacle for the implementation of hierarchical medical services.Therefore,its mechanism needed to be clarified while the corresponding policy recommendations should be proposed.

Isolated alkaloids from Coptis chinensis Franch. The compounds were identified as berberine, columbamine, groenlandicine, jatrorrhizine, magnoflorine, corydaldine and ferulic acid methylester. Then measured their bitter degree based on the electronic tongue and evaluated the antibacterial. The results based on the Electronic Tongue showed that berberine, columbamine, groenlandicine and jatrorrhizine have higher bitter degree than magnoflorine and corydaldine. And they also appeared better antibacterial activity on E. coli and S. aureus. The correlation coefficients between bitter degree and the two bacteria antibacterial activity were 0.983 and 0.911. So there was close relationship between the bitter degree and antibacterial activity of bitter components. Thus, it is confirmed further that bitter components are the material foundation of medicinal effectiveness of bitter herbs.

Objective To investigate the role and significance of neuropilin-2(NRP2)for regulating the angiogenesis of pancreatic neuroendocrine tumors(PNETs).Methods The NRP2 expression in pancreatic neuroendocrine tumer BON-1 cell line was intevened.The BON-1 cells cultural supernatants in the control group and interference group were used to treat human umbilical vein endothelial cells(HUVEC).CCK-8 was used to detect the cell proliferation,Transwell was used to detected the cell migration and the tubule formation test was used detect the pro-angiogenesis.Results The CCK-8 detection showed that there was no statistically significant difference in the supernatant treated HUVEC proliferations between the interference group and control group medium(P>0.05):the absorbancy in the control group was 0.35±0.04,while which in the interference group was 0.32±0.04.The Transwell test showed that the invasion ability of HUVEC treated with cultural supernatants in the interference group was weakened compared with the control group,the control group was(203±13)/hole,while the interference group was(100±10)/hole(P＜0.01);the tubule formation test showed that HUVEC tubular formation treated by cultural supernatant in the interference group was decreased,the control group was 40±5,while the interference group was 24±3(P＜0.01).Conclusion Interfering NRP2 expression of BON-1 cells can inhibit the vessel formation ability of co-cultured HUVEC,suggesting that NRP2 may have the pro-angiogenesis effect of PNETs,and may be a potential new target for the treatment of PNETs.

It is important to investigate the mechanical effects of morphology of prostatic urethra (PU) for benign prostatic hyperplasia (BPH). PU and bladder neck transverse diameter ratio (RPU-1), which related to vortex, and their influence on urine flow were observed by CFD. The results showed that vortexes appeared and expanded with increasing RPU on both sides of PU when RPU-1>0.79, and velocity of external urethral orifice decreased gradually. CFD is an available method for urodynamics research. The quantitative simulation of the relationship between RPU-1 and vortex was proposed for the first time, providing a new idea for advancing theory of PU lumen repair in BPH.

Objective To investigate the etiology and clinical characters of ileocecal inflammatory mass and to improve the diagnosis and therapy of ileocecal inflammatory mass.Methods From July 2006 to July 2011,the data of ileocecal inflammatory mass cases were collected,including disease history,clinical manifestations,complications,imaging results,colonscopy results,pathological results and diagnosis.The clinical characters were summarized.Results A total of 241 cases with ileocecal inflammatory mass were collected and 83 cases of them were Crohn's disease,79cases were appendicitis with periappendiceal abscess,54 cases were intestinal tuberculosis,eight cases were intestinal malignant lymphoma and 17 cases were undefined.The main manifestations of 85patients were abdominal pain,right inferior abdominal mass and fever,among which 56 patients were Crohn's disease.Among 90 patients with surgical operation,44 patients were Crohn's disease,among which 12 patients received operation because of appendicitis with periappendiceal abscess at first while the pathological examination after operation for the recurrence of ileocecal inflammatory masses proved Crohn's disease.During the course of disease,69 cases had complications of intestinal obstruction,in whom 44 cases were Crohn's disease.Nine cases had intestinal fistula,24 cases had upper gastrointestinal ulcers,one case had impetigo,and all of the above cases were Crohn's disease.Conclusions The common etiologies of ileocecal inflammatory mass were Crohn's disease.Ileocecal inflammatory mass recurrence after surgery,ileocecal inflammatory mass complicated with intestinal obstruction and abenteric manifestations were more common in Crohn's disease.

OBJECTIVETo study the protective effects of blueberry against rat immune hepatic fibrosis, specifically through the expression of hepatic cytochrome P450 2E1.

METHODFifty Wistar rats were randomly divided into five study groups (n = 10 each): Group A: normal control group, Group B: hepatic fibrosis model group, Group C: preventive group administered blueberry juice, Group D: preventive group administered Fu-Fang-Bie-Jia-Ruan-Gan tablet, and Group E: preventive group administered a combination of blueberry juice and Fu-Fang-Bie-Jia-Ruan-Gan tablet. The hepatic fibrosis model was established by intraperitoneal injection of porcine serum once daily for 12 weeks. Simultaneously, rats in preventive groups (Groups C-E) were perfused with blueberry juice or Fu-Fang-Bie-Jia-Ruan-Gan tablet or combinations of blueberry juice and Fu-Fang-Bie-Jia-Ruan-Gan tablet, respectively, for 12 weeks. The normal control group was perfused with saline for 12 weeks. All animals were sacrificed at the end of the 12 weeks, and serum levels of alanine aminotransferase (ALT) were measured and activities of superoxide dismutase (SOD), malondialdehyde (MDA), and hydroxyproline (Hyp) in liver homogenates were determined. Pathology of hepatic fibrosis was evaluated by hematoxylin-eosin (HE) and Masson staining. Expression of CYP2E1 was detected by real-time RT-PCR, immunohistochemical techniques, and Western blotting.

RESULTSSerum ALT levels were not significantly different in the control and treatment groups (F=4.056, P more than 0.05): A: 37.87+/-4.53 U/L, B: 49.23+/-9.81 U/L, C: 39.94+/-6.32 U/L, D: 40.50+/-5.70 U/L, and E: 38.24+/-8.43 U/L. Compared with Group B, the pathological stages of hepatic fibrosis were significantly reduced in the prevention groups (C-E) (F=95.097, P less than 0.05). Hyp and MDA in liver homogenates of groups C-E were significantly lower than those of Group B (Hyp: C: 472.68+/-44.14 mug/g, D: 416.12+/-39.38 mug/g, E: 429.51+/-55.14 mug/g vs. B: 603.16+/-68.92 mug/g, F=39.315, P less than 0.05; MDA: C: 0.83+/-0.06 nmol/mg, D: 0.96+/-0.08 nmol/mg, E: 0.85+/-0.06 nmol/mg vs. B: 1.24+/-0.15 nmol/mg, F=46.376, P less than 0.05). In contrast, SOD activities in Group C-E were significantly higher than those in Group B (C: 2.47+/-0.38 U/mg, D: 1.95+/-0.45 U/mg, E: 2.16+/-0.23 U/mg vs. B: 1.56+/-0.41 U/mg, F=25.557, P less than 0.05). Compared with Group A, the mRNA and protein expressions of CYP2E1 were increased in groups B-E, however the differences did not reach statistical significance (mRNA: F=0.897, protein: F=0.492, both P more than 0.05). The mRNA and protein expressions of CYP2E1 in groups C-E were lower than those of Group B, however the differences did not reach statistical significance (mRNA: F=0.897, protein: F=0.492, P more than 0.05).

CONCLUSIONBlueberry exhibits certain protective effects against porcine serum-induced hepatic fibrosis in rats. The expression of hepatic cytochrome P450 2E1 in rats with immune hepatic fibrosis is not significantly different from the normal rats. Blueberry has no effect on the expression of hepatic cytochrome P4502E1.
