OBJECTIVE:To investigate the status quo and tendency of the utilization of drug for bony metastasis cancer in our hospital. METHODS:The utilization of drug for bony metastasis cancer in our hospital from 2006 to 2009 was analyzed statistically. RESULTS:The total amount of the drug for bony metastasis cancer had been increasing. Pamidronate took up the first place of the consumption sum list and accounted for 80% of total consumption sum. Top one drug in the list of DDDs was domestical pamidronate. Utilization rate of disodium clodronate increased form 0.67% in 2006 to 31.68% in 2009. The order of DDC had not changed during 2006～2009. CONCLUSION:In recent year the drug for bony metastasis cancer has been rational and has become curative effect-oriented rather than price-oriented.

Up to now, a variety of microRNAs have been found in a number of studies, that specifically expressed in retinal neuroepithelial, lens, cornea and retinal pigment epithelium, in which miR-126 plays a certain role in the proliferation of tumor cells, the development of thymus lymphocytes and cardiovascular diseases.Some researches show that miR-126 has certain correlations with the formation of corneal neovascularization, the development of diabetic retinopathy, and the immune system related eye disease.In this paper, the current miR-126 in the role of eye disease mechanism and research progress were reviewed.

Objective To explore the relationship between osteoporosis knowledge and activities and fear of falling of elderly in the community.Method 420 elders in community were investigated with osteoporosis knowledge assessment tool (OKAT) and the modified survey of activities and fear of falling in the elderly (MSAFFE).Result The overall average score of MSAFFE was (25.36±4.58),and exercise capacity dimension scored higher (13.89±2.41).The overall average score of OKAT was (9.11±3.81).The correlation coefficient of MSAFFE and OKAT was-0.11～ 0.58(P＜0.05).The level of knowledge osteoporosis could explain 24％,18％,16％ variation of activities and fear of falling in each dimension.Conclusion The level of knowledge osteoporosis in the elderly is closely related to activity and fear of falling.Health education should be strengthened to improve the life quality of older people.

Corynebacterium glutamicum SA001 is a mutant with lactate dehydrogenase (ldhA) deletion. In order to increase metabolic flux from isocitrate to succinate, and to improve the production of succinate under anaerobic conditions,we transducted the gene aceA coding isocitrate lyase (ICL) from Escherichia coli K12 into Corynebacterium glutamicum SA001 (SA001/pXMJ19-aceA). After 12 h aerobic induction by adding 0.8 mmol/L of IPTG, the recombinant strain was transferred to anaerobic fermentation for 16 h. Succinate reached 14.84 g/L, with a productivity of 0.83 g/(L x h). Compared to C. glutamicum SA001, the activity of ICL of the recombinant strain was increased 5.8-fold, and the succinate productivity was increased 48%. Overexpression of isocitrate lyase will increase the metabolic flux of glyoxylate bypass flowing to succinate.

Objective To study the findings of CT and MRI in tongue cancer.Methods 21 cases of tongue cancer were examined by CT or MRI,CT examined 7 cases,MRI examined 14 cases.Results MRI could display the tongue cancer in all the cases,but CT only display 5 of 7 cases of the tumour.The value of CT and MRI was same in displaying soft tissue direct invasion.MRI and contrast enhanced CT could display cervical lymph node metastases.CT was superior to MRI in the diagnosis of mandible invasion.Conclusion MRI is superior to CT in the display soft tissue of tongue cancer and the metastases.CT is optimal in detection of cortical bone invasion.

Objective To explore the DNA damage in peripheral blood lymphocytes of rats exposed to sodium arsenite. Methods Thirty-two Wistar rats, weighing 180 - 200 g, equal male and female, were randomly divided into 4 groups, 8 in each group. Sodium arsenite 0(control) ,0.05,0.15,0.45 mg/L were given through drinking water for 30 days. Body weight and drinking water consumption were measured every day. Blood were collected and DNA damage in peripheral blood lymphocytes was examined by single cell gel electrophoresis.Results The increase of body mass[( 121.00 ± 38.57), ( 120.62 ± 42.80), ( 125.38 ± 48.68)g]and water intake [(36.9 ± 6.2), (37.9 ± 5.8), (39.3 ± 4.2)ml/d]in 0.05,0.15,0.45 mg/L sodium arsenite groups were compared with the control group[( 119.25 ± 47.27)g, (38.4 ± 5.1 )ml/d], and the difference were not significant (F = 0.040,0.828, all P ＞ 0.05). The tail ratios[46.25%(185/400) ,57.00%(228/400),64.00%(256/400)], tail lengths [(32.89 ± 17.18), (58.74 ± 36.28), (77.55 ± 35.73 ) μm]and tail moments [(6.29 ± 3.74), ( 11.20 ± 9.64),(17.30 ± 12.60)μm]in 0.05,0.15,0.45 mg/L sodium arsenite groups were significantly higher than those of the control group[39.25%(157/400), (18.73 ± 15.83),(2.61 ± 1.05)μm, all P ＜ 0.01], and the tail ratios,tail lengths and tail moments in lymphocytes increased with increased doses of arsenic concentration. Conclusions Low doses of arsenic exposure can induce DNA damage in peripheral blood lymphocytes of rats.

Objective To study the methods of delineating the whole length of bilateral facial nerve canals in one image. Methods High resolution computed tomography of the temporal bone was performed in 60 cases (120 ears) by Philips Mx8000 multislice spiral CT. Parameters: 120 kV, 200～250 mAs, Collimation: 0.5 mm, Pitch: 0.875, Scan time: 0.75 s/ring, Matrix: 512?512, Reformation interval: 0 1～0.2 mm, Reformation matrix: 1 024?1 024. Curved planar reformation(CPR)images were prepared along the facial nerve canal in the axial plane, and in the coronal and sagittal plane of multiplanar reconstruction(MPR). In the axial plane, a reference line was traced following the facial nerve canal from the internal auditory meatus, through the labyrinthine segment, the tympanic segment up to the second genu and mastoid segment. Another two protocols of curved reformatting were adopted: (a) a curved line was delineated along the facial nerve canal on the coronal reformatted image; (b) a curved line was drawn along the facial nerve canal on the sagittal reformatted image. The reference lines were carefully revised and moved exactly to the center of each segment of the facial nerve canal. For displaying bilateral facial nerve canals in one image, one reference line should be drawn along bilateral facial nerve canals. Results In 56 cases of 60 CPR, images in the axial plane, and coronal plane of MPR could show the unilateral or bilateral facial nerve canals clearly. The result of CPR of bilateral facial nerve canals in sagittal plane of MPR was unsatisfactory. The image on one side was often clear, but just part of it could be showed on the other. So the left and right facial nerve canals should be reformed separately. In 4 cases, CPR was unsatisfactory. In 1 of them the labyrinthine and tympanic segment had breaks because the patient′s head shook during the scanning. In 3 of them the facial nerve canals were showed unsatisfactorily because of the inexact position of head during the scanning. Conclusion The unilateral or bilateral facial nerve canals could be showed in one image by CPR. Combining the images of the high resolution CT in axial scan and MPR of the temporal bone, it would be helpful in the diagnosis of the lesions of facial nerve canal.

Objective To explore the related factors that affects the therapeutic affects and quality of life of sudden hearing loss.To establish an effective health propaganda and education strategy and improve these patient's hearing and quality of life.Methods In a retrospective study,clinical data of 90 hospitalized patients in Chinese PLA General Hospital from September 2009 to March 2010 were analyzed.The patients were divided into 2 subgroups respectively,according to with or without vertigo,psychological problems,and hypertension,diabetes mellitus and hypedipidemia.The therapeutic effects of each subgroup were analyzed respectively and ranked test of ranked data in the form of one-side sequence cross table were used in our study.Results 6 cases have been cured in hypertension,diabetes mellitus and hyperlipidemia patients and 15 cases in those without hypertension,diabetes mellitus and hypedipidemia and the difference was statistically significant(u =2.012,P＜0.05); 8 cases have been cured in those with anxiety,and 12 cases in those without anxiety,and the difference was also significant(u =2.809,P ＜0.01); 12 cases were cured in those with vertigo and 8 cases in those without vertigo,however,the difference was not significant(u =0.923,P ＞ 0.05).Conclusions With comparison of prognosis between these subgroups,a purpose-aimed health propaganda and education should be performed to make the patients understand the disease comprehensively,and to improve their self-health care consciousness,as well as to form a healthybehavior and life style.

Objective To investigate the treatment values of precise target delineation of chest MRI for lung cancer Methods From August 2011 to February 2015 , 45 non-small cell lung cancer patients were given chest CT scans and MRI scans before radiotherapy , and then active target tumor delineation , then related influencing factors were analyzed. Results All patients completed CT scans and MRI positioning. For patients that it was difficult to identify lung tissue lesions caused by lung cancer through CT , their MRI imaging showed high signal and the boundaries between the tumor and surrounding normal tissue became relatively clear. Meanwhile , 20 patients of borders were diagnosed by CT , while 25 by MRI; 36 patients with lymph node metastasis were diagnosed by CT while 40 by MRI. The difference was statistically significant (P<0.05). Univariate logistic regression analysis showed that pathological type and atelectasis were the influence factors for CT and MRI tumor target delineation differences (P<0.05), and multivariate logistic regression analysis showed the atelectasis was the main factor (P<0.05). Conclusion Compared with CT, breast MRI can precisely delineate target to improve the accuracy of target localization before radiotherapy. It can help determine lymph node metastasis and avoid the impact of atelectasis then ensure the accuracy of radiotherapy.
