Wet age-related macular degeneration (AMD) is one of major causes of blindness in elder people.Intraocular injection of anti-vascular endothelial growth factor (VEGF) -A regimen has made big breakthrough for the treatment on choroidal neovascularization of wet AM D,while long-term follow-up and necessary retreatments are the key issues to remain obtained visual acuity.Multiple strategies of wet AMD have been used in following-up and retreating based on the visual acuity,optical coherence tomography (OCT),ophthalmoscope and fluorescein fundus angiography (FFA) in abroad.However,there also are major differences in the patient' s composition,treatment habits and distribution of medical sources in China from Western.So we suggest to standardize the follow-up and retreatment strategies about intravitreal injection of VEGF-A for wet AMD as to achieve a better effectiveness.OCT-guided individual follow-up and retreatment strategies should be very helpful for maintaining a long-term efficacy,minimizing the treatment time and reducing medical cost.

Objective To study the clinical features of children with rotavirus enteritis complicated with respiratory infection.Methods The clinical features of 32 children with rotavirus enteritis were evaluated retrospectively complicated with respiratory infection (respiratory infection group) and 37 children with rotavirus enteritis complicated without parenteral infection (control group).Results 1. The respiratory symptoms became alleviative as the alimentary symptoms changed for better. 2. Duration of diarrhea weve(7.06?1.50)d in respiratory group was significantly longer than that in control group (4.73?1.31)d (t=6.90 P

Objective To investigate the lifestyles of internet addiction disorders and explore the relationship between lifestyles and internet addiction among Chinese adolescents.Methods In this cross-sectional stratified cluster sampling study,Demographic Information Questionnaire,Chinese Adolescent Lifestyles Scale (CALS)and Young's Internet Addiction Test were applied.Results (1) Adolescents with internet addiction were 275,accounting for 11.20％.Boys(15.45％) addicted the internet more than girls(7.48％).The prevalence rate of IAD was higher in students from urban(13.55％) than that in students from rural area(9.67％).The ratio of IAD was the highest in junior school students (14.01％),the second in university students (13.84％),the third in senior high school students(9.66％),and the lowest in primary school students(7.67％) (P＜0.01).(2) The internet addicts scored significantly lower on sleep,study habits,physical exercise,interpersonal relationship and coping style,compared to the normal group(P＜0.01).(3) Sleep status,study habits,physical exercise,interpersonal relationship and coping style were negatively correlated with internet addiction (r=-0.193,r=-0.319,r=-0.175,r=-0.225,r=-0.105,P＜0.01).(4)Multiple logistic regression analysis indicated learning habits and interpersonal relationship had negative predictive effects on internet addiction; whereas,the coping style showed a weak positive prediction effect on Internet addiction.Conclusion Internet addict teenagers have poor lifestyles which should be suggested to start the good behavior habit and insist on a healthy lifestyle to prevent the internet addiction disorder.

Objective To investigate the status of research and research utilization in practice among nurses of hospital of Traditional Chinese Medicine.Methods Two hundred and sixty nurses of hospital of Traditional Chinese Medicine were selected to fill out the questionnaire.Results The rates of involvement of research activities and research utilization among nurses of hospital of Traditional Chinese Medicine were low.The score of every factor ranged from the higher to the lower were communication,organization,research and nurse.Conclusions Involvements of research activities and research utilization among nurses of hospital of Traditional Chinese Medicine are insufficient.Most factors associated with nurses' low extent of research utilization are objective factors.It is pivotal for nursing managers to construct supportive professional environment,improve nurses' research and information skills and the capacity of the research utilization.

Objective To investigate the relationship between the lifestyle actual-ideal self-discrepancy and the self-regulatory fatigue.Methods A sample of 434 healthy undergraduate students were recruited from September to October 2015.They were inquired the demographic information questionnaire,the lifestyle actual-ideal self-discrepancy of Chinese Adolescent Lifestyles Scale(CALS) and the Self-Regulatory Fatigue Scale (SRF-S).Results The scores of lifestyle actual-ideal self-discrepancy in study habits ranked the highest(1.00(0.60,1.40)),followed by physical exercise(0.86(0.43,1.29)),sleep status(0.80(0.40,1.00)),diet (0.75 (0.50,1.25)),recreational activities (0.63 (0.00,1.00)),coping style (0.50 (0.25,0.75)),interpersonal relationship (0.46(0.17,0.67)) and health habits(0.25(0.00,0.50)).Furthermore,the scores of actual-ideal self-discrepancy in interpersonal relationship,study habits,sleep,physical exercise,coping style and diet were positively correlated with the scores of self-regulatory fatigue (r=0.22,0.19,0.19,0.16,0.13,0.12,P＜0.05).There was no relationship between the scores of actual-ideal self-discrepancy and the scores of self-regulatory fatigue in health habits and recreational activities(r=0.31,0.04).Conclusion The actual-ideal self-discrepancy in interpersonal relationship,study habits,physical exercise,coping style,sleep and diet were positively correlated with the self-regulatory fatigue.The reduction in these lifestyle actual-ideal self-discrepancy may help college students ease their self-adjustment fatigue.

Objective To investigate the effect of percutaneous vertebroplasty and kyphoplasty (PKP) on bone density and serum leptin in patients with osteoporotic thoracolumbar compression fractures. Methods One hundred and two patients with osteoporotic thoracolumbar vertebral compression fractures and 100 cases of healthy control were treated with PKP surgery. The serum leptin and adiponectin, and the bone mineral density of the lumbar spine were determined. Results patients Levels of the serum leptin and adiponectin in patients with osteoporotic thoracolumbar vertebral compression fracture were significantly higher than those with non osteoporotic fracture patients (P < 0.05). One month post-PVP, the levels of serum leptin and adiponectin in the two groups were significantly decreased (P < 0.05). postoperative group of The lumbar bone density at 1 month post-operation was is significantly higher than that before operation in each group (P < 0.05, respectively), with no significant difference between the two groups. The levels of serum leptin and adiponectin were negatively correlated with the bone mineral density (BMD) (P < 0.05). Conclusions tLevels of serum adiponectin and leptin were both increased in osteoporotic or non bone osteoporosis thoracolumbar vertebral compressor fractures. The percutaneous vertebroplasty forming operation could effectively reduce the serum level of leptin and adiponectin, and improve the bone mineral density of the lumbar vertebrae.

Objective To explore the cause and the interventional treatment of restenosis after percutaneous transhepatic biliary stent.Methods 20 patients with biliary restenosis after percutaneous transhepatic biliary stent placement were collected.According to drainage volume from biliary tract and degree of amelioration of jaundice,post-operation hepatic function,blood,urine and stool routines,ultrasound,CT scan and cholangiography were performed to determine the nature and location of biliary restenosis,and then all cases underwent recanalization with intervention method by the exteriorized drainage tube approach.The China-made nickel-titanium alloy stents with diameter of 10 mm and length ranged from 40 mm to 80 mm were used.Results The biliary restenosis occurred in mid-inferior segment of common bile duct in 9 patients, common hepatic duct in 7 patients and hepatic porta in 4 patients. As regarding the causes of restenosis included tumor compression in 9 cases, angulation in upper segment of stent in 3 cases, obstruction in stent by bile, food or clot in 4 cases, cholangitic stenosis in 2 cases and granulation proliferation in 2 cases.The obstruction in all cases was relived by extraction through drainage tube, drug irrigation,dredging by wire, balloon dialtion or stent replacement, so that the total survival rate was beyond 6 months.Conclusion After percutaneous transhepatic biliary stent placement in treating the malignant biliary obstruction,the rate of biliary restenosis is still high,which should be attached importance to.
