Objective:To study the effect of comfort care to alleviate postoperative pain of tibial eminence fracture by fixation. Methods:55 patients with tibial eminence fracture between Apr 2013 and Mar 2015 in our hospital were selected and divided into observation group with 26 patients and control group with 29 cases according to the nursing methods. The control group was given the orthopaedic routine nursing method, and the observation group was given the comfortable nursing method to compare two groups of patients with postoperative pain and psychological status before and after the intervention (HAMA anxiety score and HAMD depression scale). Results:There were significant differences between two groups of patients with pain score after the intervention (t=9.545, P<0.05), and HAMA and HAMD scores decline. HAMA and HAMD scores in the observation group were significantly lower than that in the control group (t=11.593, t=10.628;P<0.05). Conclusion:Comfort care can significantly relieve postoperative pain of the tibial condyle spine fractures and improve postoperative anxiety and depression. It has good clinical application value.

Objective To investigate the effectiveness of panoramic mandibular index (PMI) in detecting the bone mineral density (BMD) of mandibular bone and whole-body bone in patients with chronic end-stage renal failure. Methods A total of thirty patients with peritoneal dialysis treatment were used as experimental group and 31 healthy adults were used as control group. The panoramic jaw tomography was taken for the measurement of superior PMI (sPMI) and inferior PMI (iPMI) in two groups. The dual-energy X-ray absorptiometry (DXA) was used to detect BMD of lumbar spine bone. Data were compared between two groups. The correlation of sPMI, iPMI and BMD of lumbar spine bone was analyzed. Results All indicators including sPMI(0.262 2 ± 0.026 7 vs 0.284 2 ± 0.025 4, t=3.301) , iPMI (0.314 1 ± 0.028 3 vs 0.334 1 ± 0.027 5, t=2.808) and BMD of lumbar spine bone (0.832 3 ± 0.101 0 vs 0.906 9 ± 0.113 6,t=2.709) were significantly lower in experimental group than those in control group (P＜0.01). There was a positive correlation between sPMI and iPMI with BMD of lumbar spine bone (r=0.439 and 0.389, P＜0.05). The BMD of lumbar spine bone was significantly lower in female patients than that of male patients in control group (0.849 7±0.114 7 vs 0.968 0±0.076 3,t=3.357). The BMD of lumbar spine bone was also significantly lower in female patients than that of male patients in experimental group (0.775 4±0.068 4 vs 0.882 1±0.099 9,t=3.365). There were no significant differences in values of sPMI and iPMI between male and female patients of two groups. Conclusion The BMD of mandibular bone is lower in patients with chronic end-stage renal failure than that of the normal people. PMI index is a simple and effective method to detect the BMD of mandibular bone, which can reflect the BMD of whole body bone in patients with chronic end-stage renal disease.

BACKGROUND:Lithium chloridecan promote the proliferation and osteogenic capacity of bone marrow mesenchymal stem cels in the necrotic region after avascular necrosis of the femoral head, which has become an issue of concern. OBJECTIVE:To compare the advantages and disadvantages of bone marrow stem cel transplantation combined with lithium chloride in the treatment of rabbit femoral head necrosis. METHODS: Passage 2 bone marrow mesenchymal stem cels from 1-week-old New Zealand rabbits were cultured in 0, 5, 10, 20, 40 mmol/L lithium chloride. Forty-eight healthy adult New Zealand rabbits were selected to make femoral head necrosis models in the right femoral head using liquid nitrogen freezing method and then randomized into four groups: model group with no implantation; lithium chloride group given lithium chloride treatment at 3 days after modeling; cel transplantation group given gelatin sponge implantation and bone marrow mesenchymal stem cel suspension injection into the femoral head after modeling; combined group given bone marrow mesenchymal stem cel suspension injection and lithium chloride treatment. Intraperitoneal injection of lithium chloride (45.2 mg/kg) was given daily beginning at the postoperative 3rdday, and the treatment duration was 4 weeks. RESULTS AND CONCLUSION:Lithium chloride at 10 mmol/L had the maximum effect on the proliferation of rabbit bone marrow mesenchymal stem cels, and if the concentration of lithium chloride was > 10 mmol/L, the promotion role of lithium chloride began to decline. After combined treatment, the morphology of the femoral head was restored a little, with increased bone density and thickened trabecular bone; the level of β-catenin in the femoral head was significantly increased in the combined group compared with the cel transplantation group or the lithium chloride group. These findings show that bone marrow stem cel transplantation combined with lithium chloride treatment can promote the recovery from femoral head necrosis by increasing bone mass of the trabecular bone and bone density of the femoral head in the necrotic region.

Objective To study the influence of different contrast injection skills in interstitial magnetic resonance lymphography( IMRL) of breast cancer, and standardize the IMRL contrast injection process. Methods A total of 36 patients with invasive breast cancer were ran-domly divided into four groups. The imaging time of different contrast agent dose and local massage time on sentinel lymph node ( SLN) were analyzed. According to the results, the best contrast injection methods technology program was choosed. Results For the same massage time, different contrast agent doses showed no significant difference in the SLN imaging time (P>0. 05);For same contrast agent dose, dif-ferent massage time showed significant statistically different SLN imaging time(P<0. 05). Conclusion In clinical work, IMRL with a con-trast agent injection dose of 0. 5 mL/person, local massage 1 min after injection can successfully achieve the lymphatic system image of breast cancer.

Objective To analyze the spatial distribution characteristics of non-iodized salt at household level based on geographic information system (GIS) in Chongqing.Methods The database of non-iodized salt at county level from 2001 to 2010 was established in Chongqing.By using GIS technology,the spatial distribution and spatial autocorrelation were analyzed by ArcGIS 9.3 software.Results The rate of non-iodized salt was fluctuated between 2.35％-5.78％ during 2001-2006 and the rate was reduced to less than 2.00％ after 2007.The result of spatial autocorrelation analysis on non-iodized salt from 2001 to 2006 indicated that Moran's Ⅰindex was 0.145578,0.078801,0.108033,0.091957,0.127749,0.214302,respectively(Z value was 3.066275,1.977321,2.541619,2.309972,2.900446,3.874203,respectively,all P ＜ 0.05).The spatial distribution of non-iodized salt had marked spatial cluster through Chongqing region from 2001 to 2006.The result of local spatial autocorrelation analysis from 2001 to 2006 indicated that Fengdu and Fuling were two high-risk areas(all P ＜ 0.05).Dianjiang,Yubei,Jiangbei,Wulong and Banan were also confirmed as high-risk areas in 2001,2005 and 2006(all P ＜ 0.05).The results also indicated that the distribution of non-iodized salt in the seven high-risk areas was positively correlated.The result of spatial autocorrelation analysis on non-iodized salt from 2007 to 2010 indicated that Moran's Ⅰ index was 0.018361,0.016186,0.040769,-0.059691,respectively (Z value was 1.093310,0.787361,1.071811,-0.583820,respectively,all P ＞ 0.05).The spatial distribution of non-iodized salt was at random on the whole from 2007 to 2010.However,there were four local high-risk areas.The distribution in Fengdu and Dianjiang was positively correlated,while that in Jiangjin and Shizhu was negatively correlated.Conclusions The distribution of non-iodized salt at households level in Chongqing is changed from spatial distribution before 2006 to random distribution after 2007,but there are high value areas,which should be taken as the focus of monitoring.
