Objective:To understand the psychological characteristics of nephrotic syndrome.Methods:The personality characteristics,intelligence and social adaptive behavior(SAB) of 67 moderate to severe nephrotic syndrome aged 7～14 years were measured by means of EPQ,CBCL,CRT and SAB scales.Results:The EPQ-N score of nephritic syndrome group was higher than that of control group( P 0.05).The nephritic group got a significantly lower social/self direction factor score than the control group.Conclusion:The results showed that nephritic syndrome possessed personality characteristics of neuroticism and obvious behavior problems;and their social adaptive behavior,particularly social/self-direction factor,was significantly lower than that of normal children.

Objective To study the expression of ILD patients and health men during exercise,furthermore provide the reference of application of exercise test in ILD.Methods Cycle exercise test was used in 36 patients with ILD and 20 normal subjects,The oxygen uptake per minute(VO2),Borg Scale(BS),SpO2,and other index of exercise test were detected.Results Compared with normal subjects,The VO2max in ILD patients was decrease markedly;The BS was increased,SpO2 decreased markedly during exercise.Conclusions The results indicate that the hypoxemia and dyspnea are the limited factors of exercise in the patients with ILD;The capacity of exercise in ILD decrease compare with normal subjects.

Objective To study the expression of dyspnea and SpO2 with the patients with COPD and silicosis during exercise, further more to provide the reference in clinic treatment.Methods Cycle exercise test was used in 20 patients with COPD and 20 silicosis patients , The oxygen uptake per minute (VO2) ,Borg Scale (BS), SpO2, and other index of exercise test were detected. Results Dyspnea index as Borg scale was closely correlated with oxygen uptake (VO2) during exercise in all the patients. Borg scale slope (BSS) for quantitative evaluation of dyspnea could be derived from the linear regression line,and the BSS in COPD patients was higher than BSS in silicosis patients[(10.9?3.8)BS/(L?min) vs (7.2 ?1.9)BS/(L?min),P

Objective To study the clinical characteristics and x-ray traits of pulmonary sequestration,in order to guide preoperative diagnosis and proper treatment.Methods Data of PS patients in this hospital in ten years were summarized and analyzed.Results The pathology after operation proved that the preoperative error diagnosis rate is 71% (10/14).All patients recovered after operative treatment.The diagnosis rate can be improved by examination of CT and X-ray.Conclusions It is difficult to make a definite diagnosis before operation though PS has its relevant clinical appearances and features of X-ray. The PS cases can be made successfully diagnosed and treated dy surgery.Attention should be paid to manage the unusual artery in operation.

Objective To compare the value of ELISA and indirect immunofluorescence (IIF)method in diagnosis for autoim-mune diseases.Methods A total of 33 patients in systemic lupus erythematosus(SLE)group,59 patients in other autoimmune dis-eases group,43 patients in non-autoimmune disease group,20 people accepted physical examination in control group.The antinuclear antibody (ANA)in each group were detected by two methods and analyzed.Results The high titer ANA detected by ELISA and IIF in SLE group and other autoimmune diseases group were (2.621±1.700),(2.248±1.781);(2.71 5±0.730),(2.544±0.59). The titer ANA detected by ELISA in non-autoimmune disease group was (1.034±1.050),which was lower than(2.253 ±0.691) detected by IIF.Conclusion ELSA might improve the detection effects of ANA antibody.

Objective To study the surgery factors on chronic subdural hematoma(CSH)recurrence.Methods Two hundred and thirty-six patients with CSH were treated with trepanation and drainage.It was analyzed retrospectively on location of burr-hole,location of drainage tube,volume of intracranial pneumatocele,residual hematoma and drainage time etc.Results Half hematoma was in 177cases,two sides hematoma was in 59 cases,total was 295 hematomas.Twenty-seven hematomas were recurrent,9 cases were two sides hematoma,and 18 cases were half hematoma.There was no significant difference between recurrence rate and age,sex,drunkenness,hemorrhagic tendency,half or two sides hematoma,location of burr-hole,location of drainage tube,volume of intracranial pneumatocele and residual hematoma(P＞0.05).The recurrence rate was 9.2％(27/295).There was significant difference in recurrence rate between drainage time ≥ 3 d and＜3 d[3.5％(5/143)vs.14.5％(22/152),P＜0.01].In age ≥ 60years patients,there was significant difference in recurrence rate between drainage time ≥ 3 d and＜3 d[3.4％(4/119)vs.16.2％(18/111),P＜0.01].But in age＜60 years patients,there was no significant difference in recurrence rate between drainage time ≥ 3 d and＜3 d[4.2％(1/24)vs.9.8％(4/41),P＞0.05].Conclusion It should be taken more than 3 d of drainage time for old patients with CSH,while shorten time for young patients with CSH.

OBJECTIVE To investigate the change in antimicrobial resistance to Pseudomonas aeruginosa in our hospital from Jan 2005 to Dec 2006 and direct the using of drugs reasonably. METHODS P. aeruginosa was identified by API and VITEK2 system, and its antimicrobial resistance was determined by Kirby-Bauer method and VITEK2 system. The antimicrobial resistance rates were analyzed by WHONET5.4 software. RESULTS The resistant rates of P. aeruginosa to SAM, CTX, and CRO were higher than 70%. The resistant rate to CIP was the lowest (about 30% or so). CONCLUSIONS P. aeruginosa is still a major pathogenic bacterium in our hospital. It is very important to select antibiotics correctly according to the results of susceptibility tests.

Objective To evaluate the treatment of interapleural talc on the patients with malignant pleural effusion.Method There were 44 patients with malignant pleural effusion in the study.Every cases was inserted a chest drain to release the effusion with the rate of 200 ml per 2 hours.When there was no evidence of fluid in the pleural space as assessed by plain chest roentgenography,the talc slurry containing 4 g talc、40 ml of saline solution (0.9%) and 5 ml of 2% lidocaine was injected via the intercostal drain into the pleural space.An additional 20 ml of saline solution was used to flush the drain.Then,the drain was clamped,and the patient was asked to change position to allow adequate distribution of talc.After 2 hours,the drain was opened again.When the drainage decreased to less than 150 ml per 24 hours,the chest drain was removed.Result complete success was observed in 36 cases (81.8%),partial success in 6 cases (13.7%),and ineffective success in 2 cases (4.5%).There were 21 (47.7%) and 24 (54.4%) cases experienced pleuritic pain and fever after talc pleurodesis respectively,1 cases suffered from respiratory insufficiency which controled by using glucocorticoid later.Conclusion The talc pleurodesis is an effective treatment for the patients with malignant pleural effusion.It is safe and easily performed,and should be used extensively in clinic.

To study factors related to visual field damage in Possner- Schlossman Syndrome(PSS) .Methods 145 cases of PSS and 166 cases of promary open angle glaucoma(POAG)were followed up with tonometer and perimeter. Results①Prevalence of visual field damageamong PSS and POAG cases were 35.43% and 93.42% respectively;72.11% of the visual field damage in the PSS group was of early stage,while 78.92% of that in the POAG group was of middle or late stage.②Compared with PSS cases with no visual field damage,the damaged cases were older;their course of the disease was longer;the average IOP between crises was higher;more cases were involved binocularly;more cases demonstrated abnormal diurnal and nocturnal IOP varianle or no crossover phenomenon. ③Systematic examination was given to 26 PSS cases with visual field damage and among them, 11 cases were confirmed to be complicated with POAG. Conclusion①Although the incidence of visual field damage done by PSS is much smaller and the symptoms slighter than those done by POAG,the prognosis of PSS is by no means optimistic. ②Coses at more advanced age, with longer course, with higher IOP between crises, with binocular involvement or without IOP crossover phenomenon are at a higher risk of visual field damage. ③Serious damage can be done by PSS itself.

Objective:To establish and validate a malignant risk prediction model of solitary pulmonary nodules (SPNs) with pulmonary fibrosis in long-term smokers based on 18F-flurodeoxyglucose (FDG) PET/CT. Methods:PET/CT images of 222 SPNs combined with pulmonary fibrosis which were shown in integrated CT scan in 169 patients (all males; age 68(63, 75) years) were analyzed retrospectively. All patients were examined in PET/CT Center of the Affiliated Hospital of Qingdao University from January 2011 to December 2019 and all had definite smoking history. The benign and malignant nodules were judged according to the pathological diagnosis or follow-up imaging data of lung lesions (follow-up≥2 years). The clinical characteristics (age, smoking index), morphological characteristics (longest diameter of lesion, density, location, distribution, relative position of fibrosis, spiculation, lobulation, calcification, vacuole, vascular convergence, pleural indentation, emphysema and severity of bilateral pulmonary fibrosis) and metabolic characteristics (maximum standardized uptake value (SUV max)) of the benign and malignant lesions were analyzed by χ2 test and Mann-Whitney U test. Then multivariate logistic regression analysis was applied to select independent risk factors of malignant nodules, and a risk prediction model was established and verified by the area under the receiver operating characteristic (ROC) curve and k-fold cross validation ( k=10) respectively. Results:Among 169 patients, 222 SPNs were detected (157 malignant nodules, 65 benign nodules). Univariate analysis showed that smoking index, speculation, lobulation, vascular convergence sign, calcification, emphysema, nodule size, relative position of nodule and fibrosis, SUV max and severity of bilateral pulmonary fibrosis were significantly different between the benign and malignant nodules ( z values: 2.514-9.858, χ2 values: 4.353-18.442, all P<0.05). Result of multivariate logistic regression analysis showed that calcification, vascular convergence and SUV max were the independent risk factors of malignant nodules combined with pulmonary fibrosis (odds ratio ( OR): 0.048-2.534, all P<0.05). The risk prediction model was as follow: P=1/(1+ e - x), x=-1.839-3.033×calcification+ 0.930×vascular convergence+ 0.754×SUV max(with calcification/vascular convergence=1, without calcification/vascular convergence=0). The area under ROC curve was 0.932(95% CI: 0.895-0.969), and the sensitivity and specificity of the model were 87.9% and 86.2%, respectively. Results of k-fold cross validation showed that the prediction accuracy of 10 test sets was 0.847±0.075, and was 0.862±0.010 in training sets. Conclusions:Calcification, vascular convergence and SUV max are independent risk factors of malignant SPNs combined with pulmonary fibrosis in long-term asymptomatic smokers. The model based on the above variables presents high diagnostic efficiency in diagnosing malignant SPNs.
