Objective To investigate the clinical characteristics of peripheral arteriosclerosis in elderly males and to discuss corresponding nursing strategies. Methods 65 patients were divided into the peripheral arteriosclerosis group (the experimental group, 38 patients) and the nonperipheral arteriosclerosis group (the control group,27 patients) according to echocardiographic diagnosis. Questionnaires were designed to record factors such as age, smoking history, alcohol consumption history, primary hypertension, diabetes mellitus, coronary heart disease, blood pressure, height and body weight. Body mass index (BMI) was calculated. Results Hypertension course was much longer and proportion of patients with hypercholesterolemia and coronary heart disease and smoking index, TG, LDL-C and HDL-C levels were significantly higher in the experimental group than those in the control group. Conclusions Nursing care should be carried out from psychological, life style, medication and health education perspectives in elderly males with peripheral arteriosclerosis, aiming at improving their quality of life.

Objective To evaluate the effect of fluorin dentifrice on the microhardness and whiting of dental enamel bleached with different concentration bleachers.Methods 6%carbamide peroxide(CP)and 30%CP were selected as bleachers.Twenty undefected molars were subjected to 3 groups.Groups A and B.which composed of 8 teeth each,were tested and group C was the control one.Group A(buccal surface)and group B(buccal surface)were treated with 6%CP.Group A (lingual surface)and group B(lingual surface)were treated with 30%CP.They were bleached 30 min every day for two weeks.The teeth in group B were brushed with fluorin dentifrice for 15 min after bleached every time and then all tested samples were kept in the artificial saliva at 37℃.Vickers microhardness of all teeth and color measurement of groups A and B were made before and at the end of bleaching procedure.Results The difference of microhardness values between the bleached and control samples were not statistically significant(P＞0.05).Brushed with fluorin agent significantly increased the hardness of enamelin group B(P＜0.05).The color change was not significant between bleached samples.Conclusion Using fluoride in the interphase of bleaching makes this therapy safer,and does not affect the whitening effect.

Objective The study aimed to analyze the clinical data of patients with pulmonary embolism and summarize the clinical characteristics of pulmonary embolism,in order to improve the correct diagnostic rate and the prognosis. Methods Data of 178 patients who were cured in our hospital from January 2011 to December 2014 were analyzed retrospectively,including relative risk factors,clinical behaviors,examination data,misdiagnosis and prognosis. Results Patients with pulmonary embolism had related basic diseases and risk factors. Their clinical symptoms,signs and ordinary detection methods indicated pneumatorexis and cardiovascular injury,but lacked of specificity. The misdiagnosis rate of the first diagnosis was 48.88%,including 22 cases of the misdiagnosis to COPD, 18 cases to pneumonia and 16 cases to coronary heart disease. The misdiagnosis rate of elderly patients was 56.36%, while that of the young and middle-aged patients was 36.80%,the difference was statistically significant,P < 0.05. Computed tomography pulmonary angiography(CTPA)could accurately observe the pathological changes of pulmonary embolism,and all the patients were diagnosed by CTPA in the research. 11 cases(10%)of elderly patients died,while 2 cases(2.9%)happened in young and middle-aged patients. There was no statistical significant difference(P > 0.05). Conclusion Although the related risk factors of pulmonary embolism in patients existed,the misdiagnosed rate of the disease was high and prognosis was poor due to many confusing basic diseases. And the symptoms,signs and ordinary inspection of the patients lacked specificity. CTPA,being utilized to diagnose pulmonary embolism reliably,should be promoted.

Results 34 cases underwent electrical stimulation successfully , and received surgery without neurologic decline except 2 cases of hypokinesia. Conclusion After discharges monitoring improve the accuracy, reduce the risk of intraoperative cerebral cortex electrical stimulation.

Objective:To assess incidence of malnutrition and malnutrition risk of six department patients.Methods:The information of 1 200 patients were collected,200 in each of 6 departments in our hospital.Nutrition status was assessed according to Nutrition Risk Screening(NRS)published by ESPEN in 2001.Results:The incidence of malnutrition and malnutrition risk varied from 7.5% to 59% and 36% to 72% respectively in different department.Conclusion:The incidence of malnutrition is closely related to the kind and severity of the disease.It is nessissary to assess the nutrition status of high risk patients in time.NRS can be used simply and fastly in most inhospital patients.

Objective:To analyze the associations between attention deficit hyperactivity disorder (ADHD) and serum vitamin B levels in children.Methods:A total of 103 ADHD children who were diagnosed in the Department of Child and Adolescent Healthcare of Children′s Hospital of Soochow University from September 2018 to April 2019 were selected as the ADHD group, and 89 children of the same age who underwent routine physical examinations served as the healthy control group.The serum levels of vitamin B, including vitamin B 1, vitamin B 2, vitamin B 6, vitamin B 9, and vitamin B 12, were measured by the methods of electrochemistry.Weiss Functional Impairment Rating Scale-Parent Report (WFIRS-P) was applied to analyze the correlation between social function scores and vitamin B levels in ADHD children. Results:The levels of vitamin B 9[(12.55±2.22) nmol/L vs.(13.26±2.54) nmol/L] and vitamin B 12 [(278.54±32.00) ng/L vs.(288.90±31.32) ng/L] in ADHD children were significantly lower than those in healthy children( t=-2.064, -2.261, all P<0.05). No significant difference was observed in serum levels of vitamin B 1, vitamin B 2 and vitamin B 6 between the 2 groups (all P>0.05). Correlation analysis displayed that only vitamin B 12 level was significantly and negatively correlated with social function in the learning/school dimension ( r=-0.208, P=0.035), and no significant correlation was found between other vitamin B levels and social function (all P>0.05). Conclusions:The serum levels of vitamin B 9 and B 12 in ADHD children were obviously lower than those in healthy children of the same age.Serum vitamin B 12 deficiency had an influence on the social function of the learning/school in ADHD children.Attention to the monitoring and timely supplementation of vitamin B in childhood, especially vitamin B 9 and B 12, may be of positive significance in the prevention of the occurrence and development of ADHD to some extent.

Objective:To evaluate the efficacy and safety of oxycodone combined with dexmedetomidine in the postoperative analgesia in the patients underwent laparoscopic radical surgery of colon cancer.Methods:Sixty colon cancer patients underwent laparoscopic radical surgery and recevied patient-controlled intravenous analgesia after operation were randomly divided into control group and experiment group (n=30)using The "Envelope Method". The patients in control group were given 0.5 mg·kg-1 oxycodone,and the patients in experiment group were given 0.5 mg·kg-1 oxycodone and 2 μg·kg-1 dexmedetomidine.The parameters of analgesic pump in two groups were set as follows:the continuous perfusion rate was 1 mL·h-1 ,the single bolus was 1.5 mL,the lock-out time was 10 min,and the total volume was 100 mL.The VAS scores of pain at rest and activity pain of the patients in two groups were evaluated at exiting the post anesthesia care unit (T1 ),and at 6 h (T2 ),12 h (T3 ),24 h (T4 )and 48 h (T5 )after operation.The dose of analgesic drugs used,times of emergent rescue analgesia and anus exhaust time after operation of the patients in two groups were recorded;the postoperative adverse responses,vital signs and Ramsay scores of the patients in two groups were observed.Results:The VAS scores of activity pain at T2 -T5 and pain at rest at T2 -T4 of the patients in experiment group (P T2-T5 =0.000;P T2 =0.018,P T3 =0.001,P T4 =0.010)were lower than those in control group;the doses of analgesic drugs used and times of emergent rescue analgesia of the patients in experiment group were significantly lower than those in control group (P =0.000,P =0.029);the anus exhaust time after operation was significantly earlier than that in control group (P =0.030);the cases of nausea of the patients in experiment group were significantly lower than that in control group (P =0.023), and there were no significantly differences in the other various adverse effects of the patients between two groups (P >0.05).Conclusion: Oxycodone combined with dexmedetomidine is effective and safe for the postoperative analgesia after laparoscopic radical surgery of colon cancer.

treating rheumatoid arthritis.　METHODS: Eighty patients with rheumatoid arthritis were randomly divided into two groups with each group having 40 patients. Group one (M 8, F 32; age 46 a± s 11 a; disease history 63 mo±48 mo) was treated with anti-inflammation sub-group No.1 and No.3. Group two (M 6, F 34; 44 a±9 a; disease history 45 mo±45 mo) was treated with sub-group No.2 and No.4. One week before the initiate of the study, the originally used non-steroid anti-inflammation drugs were stopped for all two-groups patients and each patient took 2 tablets of oxaprozin po qn. At the beginning of the study the patients received 2 tablets of anti-inflammation drugs No.1 daily and 6 tables of No.3 weekly in 1st group, and 2 tablets of anti-inflammation drugs No.2 daily and 6 tablets of No.4 weekly in 2nd group respectively.　RESULTS: In the leflunomide group, the total effect rate was 93 % and the remarkable improvement rate was 85 %. In the methotrexate group, the total effect rate was also 93 % and the remarkable effect rate was 83 %, P>0.05. Nine patients (23 %) in leflunomide group had adverse reaction as mainly skin itch, nettle-like rash, decrease of leukocytes, liver malfunction and others. Seventeen parients (43 %) in methotrexate group had adverse reaction as mainly responses of digestive tract, liver enzyme elevation, decrease of leukocytes, trichomadesis, manoxenia, and others.　CONCLUSION: Leflunomide has similar therapeutic efficacy to methotrexate. However, it has relatively less toxicity.

With the population aging,the number of elderly with Alzheimer's disease or other types of dementia is increasing,which seriously threatens the health and quality of life in elderly.The early screening and detection of dementia among high-risk population and appropriate interventional measures would delay the disease course,and maintain patients' self-care abilities and dignity.Computerized neuropsychological assessment devices are economic and efficient,and suitable for screening in large population.This article reviews the theory,characteristics and application of internet-based neuropsychological assessment for age-related cognitive impairment,as well as the prospect in the future studies.

Objective:To evaluate the incidence of pretransplant sarcopenia and its effect on prognosis in patients receiving hematopoietic stem cell transplantation (HSCT).Methods:Several electronic databases (PubMed, Embase, Web of Science, Cochrane Library, EBSCO, CINAHL, CBM, CNKI, VIP, WanFang data) were searched from inception to March 2022. Cohort and case-control studies on the outcomes of HSCT patients with pre-transplant sarcopenia were collected, and the quality of the studies was evaluated using the Newcastle-Ottawa Scale. After literature screening, data extraction and quality evaluation, meta-analysis was performed using RevMan 5.3.Results:9 cohort studies were included, of which 6 were of high quality and 3 were of medium quality. The total sample size was 2,255 cases, including 862 cases in the sarcopenia group. The incidence of pretransplant sarcopenia in HSCT patients was 40% (95% CI: 0.35 to 0.46). Pretransplant sarcopenia was associated with decreased overall survival rate ( HR = 1.73, 95% CI: 1.38 to 2.04, P = 0.04) and increased non-relapse mortality after transplantation ( HR = 1.84,95% CI: 1.47 to 2.32, P < 0.01). There was no significant correlation between pretransplant sarcopenia and the incidence of acute graft-versus-host disease ( OR = 1.08, 95% CI: 0.84 to 1.39, P = 0.55). Sarcopenia before transplantation had no significant effect on the duration of hospital stay ( MD = 3.57, 95% CI: -0.13 to 7.26, P = 0.06). Conclusions:Pretransplant sarcopenia was associated with reduced overall survival and increased non-relapse mortality after transplantation. More attention to pretransplant sarcopenia is needed domestically and large-scale, multi-center, prospective studies assessing early screening for sarcopenia are necessary to provide guidance about prevention and treatment strategies.
