BACKGROUND:Bone loss to different degrees may appear within 1 year after hip replacement in the femoral or acetabular sides, and severely affect long-term stability of the prosthesis and bone strength. Thus, to reduce bone loss around the prosthesis stem after total hip replacement is significant to prolong the use time of the prosthesis and to prevent fractures surrounding the prosthesis.
OBJECTIVE:To observe the preventive effect of zoledronic acid on bone loss surrounding the prosthesis stem after hip replacement.
METHODS:A total of 80 patients after total hip replacement in the People’s Hospital of Shenxian from February 2011 to September 2014 were enrol ed in this study. They were divided into two groups (n=40). At 4 days after replacement, patients in the observation group received treatment with zoledronic acid, but those in the control group did not give zoledronic acid. The rest medication was identical between the two groups. Bone mineral density in the hip was measured before replacement and at 1 year after replacement in both groups. Serum calcium and
phosphorus levels and alkaline phosphatase activities were observed before replacement, 3 days and 1 year after medication in the two groups. Adverse reaction during medication was recorded in the observation group.
RESULTS AND CONCLUSION:The average bone mineral density was significantly decreased in both groups at 1 year after replacement, and significant differences were found as compared with before replacement (P<0.05). The average bone mineral density was significantly higher in the observation group than in the control group at 1 year after
replacement (P<0.05). Calcium and phosphorus levels were significantly diminished at 3 days after medication as compared with that before replacement (P<0.05). Calcium and phosphorus levels maintained at the level before replacement at 1 year after medication. Alkaline phosphatase activities were slightly reduced within a short time after replacement in both groups, but no significant difference was found as compared with before replacement (P>0.05). Alkaline phosphatase activities were low in the observation group at 1 year after medication, and significant difference was detected as compared with the control group and that before replacement (P<0.05). No significant difference in alkaline phosphatase activities was detectable in the control group between 1-year post medication and pre-replacement (P>0.05). Within two or three days after medication, nine patients suffered from varying degrees of muscle aches and fever in the observation group, and above symptoms were lessened after taking acetaminophen. These results verify that after total hip replacement, zoledronic acid injection can effectively prevent bone loss around the prosthesis in early stage after replacement, but fever symptoms may occur within a week after replacement. Thus, it is recommended that zoledronic acid injection can be given at 1 week after replacement. If fever and other symptoms appear, acetaminophen can be given.

Objective To explore the difference of abstract color preference among different genders,ages and education levels of hospitalized patients with neurosis.Methods The abstract color preference test was conducted in 223 inpatients with neurosis by adopting the paired comparison method.Results (1) The color preferences order in different genders of neurosis patients tended to be consistent (U=2.606,P＜0.01),green was always the most preferred color,black was the least preferred color,the preference difference had no statistical significance (P＞0.05).(2) The color preferences order in different ages of neurosis patients tended to be consistent(x2 =20.27,P＜0.01).The most preferred color of the patients in 18-30 years old group was yellow,which in ＞ 30 years old group was green,the preference difference had no statistical significance (P＞0.05).(3) The color preferences order in different education years of neurosis patients tended to be consistent(x2 =19.49,P＜0.05).The primary school and illiteracy group preferred red,and the middle school and above group preferred green;the preference difference of orange,white and black in different educational levels of neurosis patients had statistical significance(x2 =6.325,12.491,10.445,P =0.042,0.002,0.005).Conclusion The abstract color preferences of neurosis inpatients with different genders and ages have no obvious difference.The cold and warm color preferences of neurosis patients with different education levels are different.

Objective To discuss some characteristics of aggressive behavior of junior middle school students addicted to violence online game.Methods From Aug.to Dec.at 2009,6000 volunteers have been investigated with the self-made violence online game survey scale and the Chen's were screen out by CIAS,and in which 71 violence game addicts,and 66 entertainment game addicts.They were divided into two groups matched as age and sex(male 55 and female 11 in every group),average age was 14.36±0.81 years old.66 no-play game students served as control group.The mean value and standard deviation of aggressive behaviors in each group were compared with one way ANOVA with SPSS12.0 version.Results There were significant different inter groups in the behavioral scores expressed in physiological attack((21.59±4.36),(18.10±6.10,(14.92±5.61)),spoken language attack((21.04±3.98),(18.36±6.26),(15.66±5.23)),angry mood((21.37±4.43),(18.72±5.90),(16.56±5.70)),hostility cognition((21.69±5.77),(20.06±7.74),(16.39±6.85))and the total score((85.56±13.71),(75.28±22.36),(63.54±20.32))(F1-4=25.07,17.35,3.25,10.40,21.81);Moat severity attack behaviors were observed in the violence online game addictive group,but less done in other two groups(t1-4=3.48,2.68,2.65,10.27,P<0.01;t 1-5=6.66,5.37,4.48,5.30,22.01,P<0.01);and secondary was found in Entertainment online game addicts(t1-5:3.18,2.69,2.16,3.66,11.74,P<0.01).Conclusion Higher attack behavior scores are found in the violence online game in junior middle students,and entertainment online game also induce attack behavior,but is not so notable.

ObjectiveTo find incidence rate of no-suicide self injury (NSSI) of junior school students in Dalian city,and to provide some evidences for interventions for them.MethodsRandomly drawn out 1463 junior school students were served as study objects.All objects were evaluated with Ottawa Self-Injury Inventory (OSI) and self-made investigate questionnaire,75 no-suicide self-injury were screening out.ResultsThe incidence ratio of NSSI of junior school students was 5.4％,there were no significant different between the male and female students.The highest incidence ratio was found at 13 years old.The average age for first-time self-harm was (12.24±1.344) years old.There were no significant different between the male and the female students( t=- 1.415,P =0.163 ) ; Cutting Skin was the most common way of NSSI ( 12.0％ ) ; Ideation of 80％ of the NSSI was from their Own Idea.2.7％ of the NSSI can Feel Relief through NSSI behavior.93％ of NSSI was to regulate their mood.100％ students of NSSI against NSSI behavior byReading Books or Listening Music,in which 60％ of NSSI believe the method was helpful to relax their mind.78.5％ of the NSSI resisted NSSI behavior by Watching TV or Playing Games,but they did not get enough effects.60％ NSSI considered themselves without the need to treat.41.3％ of NSSI had never been to treat.2.5％ of NSSI went to hospital for the wound.ConclusionNSSI is often be found in junior school students,and highest ratio is at 13 years old.The most common method of NSSI is Cutting Skin.More NSSI aim is to release their emotion,and self-injury behavior accordance with their inner thoughts.NSSI behavior often is secret,and reading and listening to music is cut off from the relative effective way to conduct.NSSI are seldom to initiative doctor,and education organ,parents and society in a three-dimensional one of the system is necessary.

The expression of DNA ploidy, the cell cycle and Ki67 antigen in nasopharyngeal carcinoma (NPC) were studied and their relationship with the clinical biological behaviors and prognosis of NPC was evaluated. Biopsied specimens of NPC were made into cell suspension. By using cytometric double labeling Ki67 and DNA method, the expression of DNA ploidy, the cell cycle and Ki67antigen were analyzed. The patients were followed-up for about 3 years and the relationship between the above-mentioned parameters and the clinical biological behavior and prognosis of NPC were evaluated. Of the 62 cases of NPC, the DNA aneuploid accounted for 29.03 %. The S phase cells accounted for 0 to 54 % in the cell cycle and the positive expression of Ki67 ranged from 0 to 52 %.There were 40 cases of LPI (64.5 % ) including 15 negative cases and 22 cases of HPI (35.5 % ) respectively. The DNA anueploid content was positively related to the S phase cells. The patients having a low expression of Ki67 or DNA aneuploid in tumor cells were not sensitive to chemotherapy, liable to metastasis to distant organs and had a poor prognosis, while Ki67 showed no correlation with DNA ploidy and the cell cycle. It was suggested that DNA ploidy and Ki67 could be used as an independent and objective marker to evaluate the radiosensitivity and prognosis of NPC.
