Objective To analyze the common and individual training needs of palliative care among nurses in different level hospitals. Methods The self-designed questionnaire about training needs of palliative care was used to investigate 340 nurses in different level hospitals. The data were analyzed by Ridit analysis method. Results There were 24 important items and 26 unimportant items in the common training needs. Regarding the individual training needs,the concept of palliative care,basic nursing care and bereavement support were preferred by the primary-level hospital nurzes,while the principles of palliative care,basic nursing care and pain management in secondary-level hospital nurses,radiotherapy and chemotherapy care and the ethical and moral problems in palliative care in third-level hospital nurses. Conclusion Different level hospital nurs-es have beth common and individual needs in the training contents of palliative care. Ridit analysis can distinguish the differ-ences and provide reference for the training.

Objective To investigate the vascular architecture of subdermal vascular network in antebrachial region, and provide anatomic basis for designing the subdermal vascular network skin flap in the antebrachial region. Methods Anatomical observation and measurement of the blood supply, arterial architecture and venous return of the subdermal vascular network skin flap in anterior antebrachial region were performed on 8 fresh adult specimens perfused with latex and black ink. Results It was found that 4～15 or more fine perforators derived from each the terminal end of the brachial artery and radial or ulnar arteries in anterior antebrachial region, and their diameters were between 0.2～0.9 mm. The anatomical studies showed that the fasciocutaneous perforators supplying the in anterior antebrachial region were found to form rich "spider nevus"arterial networks on the subdermal layer. Moreover, the subdermal vascular networks were also found to give off fine arterial branches into papillary and superficial fascia layers, respectively, to form papillary vascular plexus and superficial fascia vascular network, and all of the vascular networks were anastomosed densely each other. The subdermal venous networks were also anastomosized in plexus and drained into the deep vein. Conclusion Either a random or an axial subdermal vascular network skin flap of the anterior arm can be designed according to the need of recipient defect, and the latter may also be designed as a transfer or a free subdermal vascular network skin flap according to the size of the arterial diameter in the pedicle of skin flap.

Objective:To evaluate the antimicrobial effect of ozonated water on the putative periodontopathic bacteria.Methods:Pophyromonas gingivalis (P.g)ATCC33277,Haemophilus actinomycetemcomitans (H.a)ATCC29522,Fusobacterium nucleatum (F.n)ATCC1 0957 and clinically seperated strain of P.g(C -P.g)were treated by ozonated water with ozone concentration(mg/L) of 0.03,0.06 and 0.1 2 for 30,60,90 and 1 20 s respectively.The bactericidal effect was tested by bactericidal assay.H2 O2 was used as the positive control and distilled water as the negative control.Results:The antimicrobial rate of ozonated water agaist the bacteria increased with the ozone concentration increase.There was no statistic diffrence of the effect on P.g and C -P.g(P >0.05).Linear regression analysis showed that the βvalues of the concentration factor were over 0.95,that of the time factor under 0.1 1 .Conclu-sion:The ozonated water has dose-dependent bactericidal effect on P.g,H.a and F.n.

Objective To analyze the clinical significance of aberrant hepatic artery which originated from superior mesenteric artery in liver cancer and gastric cancer operations.Method Four hundred liver cancer patients who underwent digital subtraction angiography (DSA) and multislice spiral computed tomography angiography (MSCTA) and 86 gastric cancer patients who underwent MSCTA between June 2008 and June 2010 and operated at the First Affiliated Hospital of Guangxi Medical University were included in this study.Preoperatively,the origins of the aberrant hepatic arteries from superior mesenteric arteries were detected by medical imaging.Postoperatively,immunohistochemistry of lymphoid tissues around the aberrant hepatic arteries of the gastric cancer patients were performed using recombinant human cytokeratin 20 (CK20) and carcino-embryonic antigen (CEA) to determine the incidence of lymph node metastases around the aberrant arteries.Results Among 486 patients,49 patients with liver cancer and 14 patients with gastric cancer had an aberrant hepatic artery which originated from the superior mesenteric artery.The rate was 12.96％ (63/486).The hepatic artery ran in front of the pancreas in 2 patients (3.17％) and behind the pancreas in 61 patients (96.83％).Immunohistochemical analyses of CK20 and CEA were negative which revealed no metastases in the lymphoid tissues surrounding the aberrant arteries.Conclusions Aberrant hepatic artery originated from the superior mesenteric artery can be classified into the pre-pancreas type and postpancreas type.The majority of aberrant hepatic artery belonged to the post-pancreas type.The clinical significance of aberrant hepatic artery is that the hepatic hilar lymph nodes should be dissected in liver cancer and gastric cancer operations.

[Objective]To investigate the ability of repairing bone defect with the combination of recombinant human insulin-like growth factor-1(rhIGF-1),coralline hydrolyapatite(CHA) and autogeneous red bone marrow(ARBM) by way of imaginology.[Method]Bilateral middle radius periosteum-bone defects (11mm in length) were created in 54 Chinese rabbits,and were ramdonly devided into 6 groups(each group containning 18 radial defects of one forearm): group A, defects transplanted with rhIGF-1/CHA/ARBM,group B,with CHA/ARBM,group C,with rhIGF-1/CHA,group D,with CHA,group E,with autograft,group F,no implant.At 2,4,8,and 12 weeks postoperation,the repair effects of defects were evaluated by observation of gross appearance,roengenodiagnosis and radionuclide bone image assay.[Result]In group A,radiological and bone density image analysis showed that the defects were bridged well at 12 weeks postoperatively and was significantly superior to those of any other groups(P0.05).[Conclusion]The recombinant compound rhIGF-1/CHA/ARBM,which possesses the potential ability of osteogenesis,osteocondution and osteoinduction for bone defect repairing,can enhance bone healing and serve as a new type of bone substitute.

Objective To investigate the potential effect of 4-amino-pynidine(4-AP)on human cervical carcinoma cell line HeLa to 252Cf neutron ray.Methods HeLa cells were treated with 4-AP(0,1,5,10,20 mmol/L,respectively)and then exposed to 0.67 Gy 252Cf neutron ray.The effect of 4-AP on proliferation of HeLa cells was assessed by MTT assay.Cell apoptosis were detected by flow cytometry.Reverse transcription polymerase chain reaction(RT-PCR)and Western blotting were used to investigate the levels of HIF-1? mRNA and protein of HeLa cells treated with 4-AP(0,20 mmol/L)and 0.67 Gy 252Cf neutron ray.Results After HeLa cells treated with 0,1,5,10,20 mmol/L 4-AP were exposed to 0.67 Gy 252Cf neutron ray for 48 h,their inhibitory rate was 0,(38.81 ?3.45)%,(46.63?3.88)%,(63.58?6.19)%,(77.51?8.87)%,and their apoptotic rate was(3.15?0.85)%,(8.01?1.19)%,(16.00?1.58)%,(47.20?3.18)%,(62.56?4.27)%,respectively,suggesting 4-AP may inhibit the proliferation of HeLa cells and induce their apoptosis in a dose-dependent manner(P0.05).However,after treated with 20 mmol/L 4-AP and exposed to 0.67 Gy 252Cf neutron ray for 24,48 and 72 h,the optical density ratio of HIF-1? mRNA/?-actin of HeLa cells was(0.401?0.121),(0.364?0.142),(0.257?0.137),(0.165?0.099),while the optical density ratio of HIF-1? protain/?-actin were(0.879?0.117),(0.645?0.115),(0.312?0.114),(0.130?0.118),showing that the levels of HIF-1? mRNA and protein both declined(P

The authors reported their experience in treatment of 17 patients with hepato-gastrointestinal neoplasms with lipiodol embolization chemotherapy via subcutaneous infusion port by a non-surgical method since March, 1994. According to the seldinger method implanted catherter was placed in the suitable target artery, and the Subcutaneous infusion port was linked to the implanted catheter through a subcutaneous tunnel. Antitumor chemotherapeutic drugs, biological response modifiers and lipiodol were injected through the port. These results suggest that the non-surgical implant method is simple, safe and effective for regional chemotherapy.
