Podoplanin (PDPN), being mucin-like transmembrane sialoglycoprotein, is expressed on lymphatic endothelial cells, with its significant role in the development of inflammation, separation of blood and lymphatic circulation, platelet aggregation, integrity of the renal filtration barrier and alveolar. In recent years, many researches have demonstrated that PDPN is overexpressed on the surface of some tumor cells. The interaction between PDPN and CLEC-2 plays an important role in the development of tumor growth, migration and transfer, therefore, anti-PDPN antibody offers a new direction for the treatment of tumor patients. This paper aims at reviewing the progress and application prospect of PDPN.

Objective To understand the needs for and supply of clinical research consultation at the clinical epidemiological unit (CEU) in a general hospital. Methods Data were collected from work records of 2008 of CEU and were analysed. Results There were three faculties and three graduate students in the CEU, who altogether provided 272 consultations in 2008. 147 of the consultants were doctors (54.0%), and 90 were graduate students (33.1%). With regard to the content of consultation, 106 (39. 0%) were for bio-statistical methods, 96 (35. 3%) for project design, 36(13.2%) for paper writing and 24 (8.8%) for others. The professor of the CEU provided more consultation on project design (71/139, 51.1%) than assistant professors (22/151, 19.1%) and graduate students (3/18, 16.7%) (P＜0.01). The assistant professors (66/151, 57.4%) and graduate students (10/18, 55.6%) provided consultation on bio-statistical methods more than the professor (30/139, 21.6%) (P＜0. 01). Conclusion Doctors and graduate students in the general hospital need clinical research consultation service from the CEU. It is necessary and possible to establish a CEU in general hospital to meet the needs of clinical epidemiological consultation. The free consulting policy is effective in improving the accessibility and satisfaction of the consulting service.

Hedgehog (Hh) signaling is critical for embryonic development and in differentiation,proliferation,and maintenance of multiple adult tissues.Deregulation of the Hh pathway is associated with Multiple pathological steps of PDAC(Pancreatic ductal adenocarcinoma).A prominent desmoplastic stromal reaction is the pathological hallmark of PDAC,it contributes to the formation of the hypovascular and hypoxic microenvironment of PDAC.And Hedgehog signaling is one of the most crucial pathways that maintains and activates the stroma.Clinical trials of Hedgehog signaling inhibitors in treatment of PDAC has been conducted,but results have been disappointing.Recently,to undercover the reason of the failure of clinical trial,more work has been done to uncovering the underlying role of stroma in PDAC.

Objective To explore the diagnostic value and clinical significance of simultaneous detection of AFP,AFU and TSGF in patients with primary hepatic carcinoma(PHC).Methods Serum AFP,AFU and TSGF were detected simultaneously in 62 patients with PHC and 30 controls.Results The levels of AFU and TSGF in primary hepatic carcinoma were all significantly higher than that of controls(P

Tumor-associated macrophages (TAMs) exist in the tumor microenvironment,and can be affected by various anticancer treatments and further affect tumor progression.Increasing evidence suggests that many of the clinical antitumor measures can play a unique and effective antitumor effect by regulating the recruitment,polarization and related pro-tumor behavior of macrophages in the tumor microenvironment.Now,tumor microenvironment immune remodeling has become a hot spot in the research of anti-tumor therapy.This paper reviews the related research progress on antitumor effects of TAMs as an therapeutic target.

Objective To observe the anti-shock effect of rapid infusion of 7.5% sodium chloride(NaCl) in dog with hemorrhagic shock. Methods Five mongrel dogs were bled to mean arterial pressure(MAP) of 5.33～6.70kPa, and this pressure was maintained for 1 hour. Each dog received 7.5% NaCl (4ml/kg) intravenously, the infusion time was 2 min. The observation time was 4 hours. Results During the infusion period, the blood pressure was obviously lower than that of the shock period(P

Objective:To study the effects of ozone aging on the color stability of the SY-1 silicone elastomer. Methods :40 SY-1 silicone elastomer samples were prepared and grouped into 4 with 10 in each group. The samples in each group were painted with gouache color, oil pigment and inorganic salt respectively, one group was used as the control. Then the samples were treated with ?=10 -4 % ozone at 10～16 mm/s for 72 h. The color of the samples were measured by 1976 CIE L *a *b * standards of chromatic aberration before and after ozone treatment. The chromatic aberration was expressed as △E=〔△L *)2+(△a *)2+(△b *)2〕 1/2. Results :After 72 hours of ozone aging, △E of the samples in the groups of control, gouache color, oil pigment and inorganic salt was 0.55?0.11, 3.55 ? 0.09, 1.40 ? 0.11 and 1.57 ? 0.07 respectively ;Conclusion:Under the ozone aging condition, the SY-1 silicone elastomers stained with oil pigment and inorganic salt may have better color stability than that with gouache color.

Objective To observe the changes of adrenal cortical function in children with growth hormone deficiency before and after treatment with recombinant human growth hormone. Methods Seventy-two children diagnosed with GHD who received rhGH treatment for no less than 6 month were included, among whom there were 32 children who were accompanied with adrenal cortical hormone (ACTH) deficiency. The changes of fasting plasma cortisol (COR) and ACTH levels before and 3 and 6 months after treatment with rhGH were retrospectively analyzed. Results Thirty-two children with ACTH deficiency were treated with rhGH after COR level reached normal by the supplementing exogenous hydrocortisone. There was negative correlation between COR level before treatment and the HC dose that make the COR reach normal lowest limit level (r?=?-0.899, P??0.05). The level of COR was obviously decreased after treatment with rhGH, and there was statistical difference compared with that before treatment (P?

Objective: To observe the effect of extracorporeal shock wave therapy (ESWT) on proliferation, cell cycle and intercellular adhesion molecule-1 (ICAM-1) expression in human umbilical vein endothelial cells (HUVECs). Methods: HUVECs were culturedin vitro at the concentration of (1×105/ml) and the cells were divided into 2 sets of groups:CSWT group, the cells were treated by different energy of (0.03, 0.09, 0.18, 0.24) mJ/mm2 respectively and corresponding Control group, in which the cells had no CSWT. HUVEC proliferation was detected by CCK colorimetric method, cell cycle was measured by lfow cytometry, mRNA and protein expressions of ICAM-1 were examined by RT-PCR and Western blot analysis respectively. Results: Compared with Control group, (0.09 mJ/mm2) CSWT group had promoted HUVECs proliferation,P<0.05 and the other CSWT groups were similar to corresponding Control groups,P>0.05; (0.09 mJ/mm2) CSWT group showed decreased proportion of G0/G1 stage and increased S and G2/M stages, allP<0.05; while (0.03 mJ/mm2) CSWT group only increased the proportion of G2/M stage,P<0.05 and the other CSWT groups were similar to corresponding Control group,P>0.05. Compared with Control group, (0.09 mJ/mm2 ) and (0.03mJ/mm2) CSWT groups showed increased mRNA expression of ICAM-1 (9.27±0.95) vs (1.02±0.27),P<0.001 and (7.08±0.60) vs (1.02±0.27),P<0.01; (0.09 mJ /mm2) CSWT group had elevated protein expression of ICAM-1,P<0.05. Conclusion: ESWT especially at (0.09 mJ/mm2) may accelerate cell cycle transition from G0/G1 stage to S and G2/M stages, promote HUVECs proliferation and increase ICAM-1 expression which may play important roles in ESWT facilitated angiogenesis in vitro.
