OBJECTIVEThe aim of this study was to observed the influence of deposition time on chromatics during nitrogen-doped diamond like carbon coating (N-DLC) on pure titanium by multi impulse are plasma plating machine.

METHODSApplying multi impulse are plasma plating machine to produce TiN coatings on pure titanium in nitrogen atmosphere, then filming with nitrogen-doped DLC on TiN in methane (10-80 min in every 5 min). The colors of N-DLC were evaluated in the CIE1976 L*a*b* uniform color scale and Mussell notation. The surface morphology of every specimen was analyzed using scanning electron microscope (SEM) and X-ray photoelectron spectroscopy (XPS).

RESULTSWhen changing the time of N-DLC coating deposition, N-DLC surface showed different color. Golden yellow was presented when deposition time was 30 min. SEM showed that crystallization was found in N-DLC coatings, the structure changed from stable to clutter by varying the deposition time.

CONCLUSIONThe chromatics of N-DLC coatings on pure titanium could get golden yellow when deposition time was 30 min, then the crystallized structure was stable.

The physical,neurological conditions and intelligence test were taken regularly. To investigate the psychological state, actions, temperament and family conditions when they were2-3 years old.Results Mental development index(MDI) and physical development index(PDI) in early interventional group were significant higher than those in group 2(P

Objective To study the tolerance to 188Re-1-hydroxy-1 ,1-ethylidene disodium phosphonate(HEDP) in patients with bone pain caused by osseous metastases. Methods Thirty-one patients(10with prostate cancer, 9 with breast cancer, 3 with lung cancer, 5 with liver cancer, 2 with rectal cancer, 1with esophageal cancer and 1 with renal cancer) received a single injection dose of 188Re-HEDP. The patients were divided into four groups according to the injection dose: 20 MBq/kg (6 patients), 30 MBq/kg(6 patients), 40 MBq/kg (9 patients), and 50 MBq/kg (10 patients). Haematological toxicity (WHO grading) of grade Ⅲ- Ⅳ was considered unacceptable. Vital signs and adverse effects after injection were recorded for 8 weeks. Blood counts were measured weekly during a period of 8 weeks. Biochemical parameters and electrocardiogram were assayed at week 4 and 8. Statistical analysis was performed for per-protocol (pp) population (t-test). Results Twenty-seven patients belonged to PP population with 5 in the group of 20 MBq/kg, 5 in the group of 30 MBq/kg, 8 in the group of 40 MBq/kg and 9 in the group of 50 MBq/kg.No obvious adverse effects and no significant change of vital signs, electrocardiogram, liver and renal function were found after injection. Alkaline phosphatase was slightly higher than baseline at week 4 and 8 after therapy, but the difference was not statistically significant. In the 20 MBq/kg group, reversible grade Ⅰ leucopenia was noted in 1 patient. In the 30 MBq/kg group, 2 patients showed reversible grade Ⅰ leucopenia including 1 alone with reversible grade Ⅲ thrombopenia. In the 40 MBq/kg group, reversible grade Ⅰ leucopenia and thrombopenia was observed in 1 patient and reversible grade Ⅱ leucopenia and thrombopenia in another patient. In the .50 MBq/kg group, 3 patients showed reversible grade Ⅱ leucopenia. The lowest level of thrombopenia was at week 4(143.5 × 109/L), leucopenia at week 6 (5.4 × 109/L) and anaemia at week 8(t = 3.1325, 3.3156, 3.4917, all P ＜ 0. 05 compared with baseline). At week 8, the mean level of platelet and leucocyte recovered to baseline. "Bounce pain" was found in 2 of 27 patients (7.41%).Conclusions The dose of 20 MBq/kg, 30 MBq/kg, 40 MBq/kg or 50 MBq/kg of 188Re-HEDP do not cause significant side effects on cancer patients with bone metastases, though there is a tendency that the haematological toxicity may increase as the dose of 188Re-HEDP increases.

Objective To investigate the distribution of high-arsenic drinking water in Honghu city of Hubei province in order to provide a scientific basis for prevention and control of endemic arsenic disease.Methods Investigations were made in 22 townships(towns,districts),68 natural villages of the drainage areas of the Dongjing River,the Neijing River and the Yangtse River in 2006 and 2007,with the townships(towns,districts)around Shahu town in Xiantao city as the focal point.1000 water samples were drawn each year,which was 10% of all the wells in every natural village.Using sampling investigation,water arsenic Was determined by half-quantitative fast reagent kit.All samples of water with arsenic exceeding the standard(≥0.03 mg/L)were re-determined according to state standard.Surveys on the disease was carried out in the villages(brigades)where arsenic exceeded the standard.Results A total of 2000 samples were surveyed from 68 natural villages,of which there were 401 samples from 48 villages exceeding the standard in a rate of 20.05%(401/2000).The highest arsenic content Was 0.71 mg/L.The high arsenic water sources were distributed mainy in the drainage areas of the Dongjing River and the Neijing River,but no patients with endemic arsenic disease were found.Conclusions The high arsenic water sources are distributed mainly in the drainage areas of the Dongjing River and the Neijing River.It is suggested that the interrelated government departments should take precise measures to impmve the quality of drinking water and ensure safe water to the residents in high arsenic areas.

BackgroundWith the increasing prevalence of dry eye and the continuous improvement of living standards,the problem of dry eye more and more get the attention of people.At present,China still lacks the large population-based epidemiological data of dry eye. Objective To investigate the prevalence and possible risk factors of dry eye in a community of Huidong County of population aged 14 and over.Methods From September 2010 to January 2011,using questionnaires and examination of dry eye related,2800 people were selected randomly for cross-sectional survey.Those suspected as dry eye were examed by the SchirmerⅠtest ( S Ⅱ T),tear-film breakup time(BUT),corneal fluorescein staining(F1).Results In the 2475 questionnaire effectively,154 persons were diagnosed as dry eye,and the prevalence rate of dry eye was 6.22％,8.06％in females,4.14％in males.The prevalence rate increases with age.The S Ⅰ T and BUT decreased with increasing age.S Ⅰ T and BUT in females are less than males.Foreign body sensation is the primary complaints of patients.Logistic analysis showed that the most common risk factors in dry eye are age and gender.The system disease and eye diseases,eye fatigue and long exposure to dust are also main determinants.ConclusionsThe population prevalence rate of dry eye increased with age,the prevalence rate of dry eye in females is higher than that in males.The key factors associated with dry eye are age,gender,systemic disease and eye diseases,occupation,working environment.

Objective To investigate the value of the imaging findings of soft tissue abnormality in the differential diagnosis between osteomyelitis and malignant bone tumor.Methods The CT and MRI findings of soft tissue changes in 57 cases of osteomyelitis and 70 cases of malignant bone tumor were retrospectively defined,observed,recorded and statistically analyzed.Results In 57 cases of osteomyelitis, 54 cases were examined with CT,and soft tissue swelling was presented in 52 cases (degree Ⅰin 19 cases, degreeⅡin 16 cases,degree Ⅲin 17 cases).Abscess-like cysts in soft tissue occurred in 6 cases,masses in 5,air in 1,fat-fluid level in 1 and sinus tract in 1.Among 14 cases examined with MR imaging,soft tissue swelling was presented in all cases (degreeⅠin 2 cases,degree Ⅱin 6 cases and degree Ⅲin 6 cases). Abscess-like cysts appeared in 3 cases and showed high signal in diffusion weighted imaging, mass in Ⅰand fat-fluid level in 1.Among 54 cases examined with CT in 70 cases of malignant bone tumor, soft tissue swelling was presented in 44 cases (degreeⅠin 29 cases,degreeⅡin 12 cases,degreeⅢin 3 cases).Soft tissue masses appeared in 49 cases,bone shell and shell-like calcification in 16 cases and neoplastic bone and neoplastic calcified cartilage within soft tissue mass in 25 cases.Among 49 cases examined with MR imaging,soft tissue swelling was presented in 46 cases (degree Ⅰin 21 cases,degreeⅡin 17 cases and degree Ⅲin 8 cases),and soft tissue masses appeared in 43 cases.The degree of soft tissue swelling and the occurrence of abscess-like cyst,mass,bone shell or shell-liked calcification in the rim of mass,neoplastic bone or neoplastic calcified cartilage in masses showed significant difference(P

OBJECTIVE: To evaluate the protective effect of recombinant human granulocyte colony stimulating factor (rhG-CSF) on acute hepatic failure induced by galactosamine (D-GalN) and lipopolysaccharide (LPS) in mice, and to explore its mechanism. METHODS: The mice were intraperitoneally administered D-GalN (800 mg/kg) and LPS (10 microg/kg), and then were intraperitoneally injected either saline (the control group )or rhG-CSF at 300 microg/kg body weight (the therapy group) at 4 h, 2 h and 0 h before the D-GalN/LPS injection. The survival rate of the mice was estimated at 24 h after the D-GalN/LPS injection. The degree of hepatic injury was evaluated at 6 h after the D-GalN/LPS injection, and the levels of TNF-alpha, IFN-gamma, IL-6 and IL-10 mRNA were simultaneously measured by semiquantitative RT-PCR. RESULTS: The survival rate of the therapy group was significantly higher than that of the control group (68.4% vs 20%, P<0.01). As compared with the control group, the degree of liver injury in the therapy group significantly decreased (P<0.05), and the levels of TNF-alpha and IFN-gamma mRNA in the hepatic tissue also reduced remarkably (P<0.01, respectively), while the levels of IL-6 and IL-10 mRNA increased (P<0.01, respectively) at 6 h after the D-GalN/LPS injection. CONCLUSION G-CSF can protect the mice from acute hepatic failure induced by D-GalN/LPS.
