Plastic bronchitis is a rare condition characterized by bronchial casts, that may result in respiratory failure, suffocation and even death.Therefore, early diagnosis and treatment are of great significance.This article summarizes the imaging characteristics of plastic bronchitis, in order to further improve the understanding of the disease among pediatricians, radiologists, and emergency physicians.

Objective To discuss the need for performing intravenous urography(IVU) in patients with non-muscle invasive bladder cancer before surgery. Methods From 1997 to 2008,1968patients were diagnosed as non-muscle invasive carcinoma of the bladder with pathological confirmation. All patients underwent ultrasonography, cystoscopy and IVU prior to surgrey. The x2 test was used for statistical analysis. Results The incidence of upper urinary tract urothelial tumors (UUTUT) was 11. 0% (216 cases). Two hundred and fifteen (13. 6%) suffered simultaneous UUTUT detected by IVU in 1528 patients with bladder cancer who had intermittent painless gross hematuria, while only 1 (0.3 %) suffered simultaneous UUTUT in 386 non-symptomatic patients (P＜0.01). Among 120 patients with bladder cancer whose upper tract was abnormal detected by ultrasonography,120 (100. 0%) suffered simultaneous UUTUT detected by IVU, and of 1848 patients who were normal in upper tract by ultrasonography, 96 (5. 2%) suffered simultaneous UUTUT detected by IVU (P＜0. 01). Of the patients with no abnormalities in upper tract by ultrasound, 37(3. 0%) suffered simultaneous UUTUT detcted by 1VU in 1247 patients with single bladder tumor,and 59 (9.8%) suffered simultaneous UUTUT in 601 patients with multiple bladder tumors (P＜0.01). Of the patients with single bladder tumor who had no abnormalities in upper tract by ultrasonography, 2 (0.2%) suffered simultaneous UUTUT detected by IVU in 822 patients with the diameter of the tumor＜1.0 cm, and 35 (8. 2 %) suffered simultaneous UUTUT in 425 patients with the diameter≥1. 0 cm (P＜0.01). Of the 1541 patients with histological G1, 48 (3.1%) suffered simultaneous UUTUT detected by IVU, and of the 427 patients with histological G2- G3, 168 (39. 3%)suffered simultaneous UUTUT (P ＜ 0. 01 ). Conclusion Patients with the following characters should undergo IVU before surgery: hematuria, abnormal upper urinary tract by ultrasonography,multifocal tumours, the diameter of the single bladder tumor≥1. 0 cm and high gradc tumors.

Objective To study the clinical features,diagnosis and management of small cell carcinoma of the bladder (SCCB).Method The clinical data of 18 cases of patients with small cell carcinoma of the bladder were analyzed retrospectively and the literature were reviewed.There were 16 males and 2 females,ages 54 to 81 years (median age,61 years).Clinical manifestations included gross hematuria in 11 cases,urgency in 2 cases,dysuria in 2 cases and postoperative review after TURBT of bladder urothelial carcinoma in 3 cases.The median tumor size was 3.35cm (ranged,1.0 to 6.0 cm).2 cases underwent TURBT and intravesical chemotherapy regularly were followed after surgery.3 cases underwent partial cystectomy,intravenous chemotherapy combined with radiotherapy was followed in one case,the other 2 cases refused the following therapy.13 cases underwent radical cystectomy,intravenous chemotherapy was followed in 2 cases,pelvic radiotherapy was followed in 2 csaes and intravenous chemotherapy combined with radiotherapy was followed in 2 cases,the other 7 cases refused the following therapy.Results 11 cases were pure SCCB,7 cases were mixed SCCB,all with urothelial carcinoma.T1N0M0 in 3 cases,T2N0.1M0 in 4 cases,and T3N0-2M0 in 11 cases.The duration of follow-up was from 5 to 35 months after surgery.9 cases died of tumor metastasis,9 cases are still alive,except 1 case with lymph node metastasis,the other 7 cases are free of tumor recurrence or metastasis.Conclusions SCCB is rare,with high malignant degree and poor prognosis.The prognosis of the pure SCCB may be worse than the mixed SCCB.The diagnosis depends on pathology examination.Radical cystectomy is the main treatment method,the strategy of bladder-preserving may be an attempt for proper SCCB patients.Adjuvant therapy plus surgery may be better.

Objective:To explore the effect of "321" health education model in elderly patients with osteoporotic thoracolumbar fractures (OTF) .Methods:From January 2019 to June 2021, convenience sampling was used to select 112 elderly patients after OTF surgery in Hefei First People's Hospital as the research object. The patients were divided into the experimental group and the control group by random number table method, 56 cases in each group. The control group was given routine nursing and health education for patients after OTF surgery, while the experimental group was given "321" health education. The scores of Health Behavior Questionnaire, incidence of complications, and quality of life scores were compared between the two groups before intervention and after 6 months follow-up.Results:There were 54 and 51 patients in the experimental group and the control group, respectively, who completed the study. After 6 months of follow-up, the total score and the dimension scores of the Health Behavior Questionnaire in the two groups were higher than those before the intervention, except for the other behavior dimension, the total score of the Health Behavior Questionnaire and the scores of other dimensions in the experimental group were higher than those in the control group, all differences were statistically significant ( P<0.05) . The incidence of complications in the experimental group (3.70%, 2/54) was lower than that in the control group (15.69%, 8/51) , and the difference was statistically significant (χ 2=4.669, P=0.031) . The total score and the dimension scores of quality of life in the two groups were lower than those before education, and the total score and the dimension scores of quality of life in the experimental group were lower than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The "321" health education model in elderly patients after OTF surgery is beneficial to promote the osteoporosis prevention and health behavior of elderly patients after OTF surgery, reduce the occurrence of complications after OTF surgery, and improve the quality of life of patients.

Objective:To compare the effect of a 3D-printed ankle and foot orthosis (AFO) with that of a traditional AFO on the recovery of walking function after a stroke.Methods:Thirty-four hemiplegic stroke survivors were randomly divided into an observation group and a control group, each of 17. Both groups were taught good limb placement and given joint mobility, standing and walking training for 4 weeks wearing either a 3D-printed or a conventional AFO. Walking speed, walking endurance, and dynamic balance were evaluated before and after the experiment using the 10-metre walk test (10MWT), the 6-minute walk test (6MWT), and the timed up and go test (TUGT). Integrated electromyography (iEMG) was also performed on each subject′s bilateral rectus femoris, anterior tibialis, and gastrocnemius muscles during walking, and their healthy and affected side iEMG results were compared to assess the activation of the affected lower limb muscles.Results:After treatment, the 10MWT, 6MWT, and TUGT results of both groups had improved significantly, but the observation group′s average results were then significantly better than those in the control group. The iEMG disparities between the healthy and affected sides had also decreased significantly, but on average the disparities in the observation group were significantly smaller than in the control group.Conclusion:Both types of AFO can effectively improve the walking speed, walking endurance, and dynamic balance of hemiplegic stroke survivors and promote muscle activation in the affected lower limb. A 3D-printed AFO is relatively more effective.

ObjectiveTo investigate the effect of sustained virologic response on disease progression and the development of hepatocellular carcinoma (HCC) in patients with compensated hepatitis B cirrhosis receiving antiviral therapy with nucleos(t)ide analogues (NAs). MethodsA total of 542 patients with compensated hepatitis B cirrhosis who attended Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from January 1 to December 31, 2013, received antiviral therapy, and were followed up for more than 5 years were enrolled, and according to the status of virologic response during follow-up, they were divided into a sustained virologic response cohort with 496 cases and a non-sustained virologic response cohort with 46 cases. With disease progression as the outcome event, general information and examination data were collected during the 5-year follow-up period. The t-test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups. A multivariate logistic regression analysis was performed; relative risk and 95% confidence interval (CI) were used to investigate the degree of correlation of factors measured with the progression of liver cirrhosis. The life-table method was used to calculate the 1-, 3-, and 5-year progression-free survival rates, and the Kaplan-Meier method was used to plot survival curves; the log-rank test was used for univariate analysis, and the Cox regression model was used for multivariate regression analysis. ResultsFor the 542 patients, the mean progression-free survival time was 62.50 months (95% CI: 61.01-63.92), and the 1-, 3-, and 5-year progression-free survival rates were 94%, 82%, and 71%, respectively. The sustained virologic response cohort had a significantly longer mean progression-free survival time than the non-sustained virologic response cohort ［63.10 months (95% CI: 61.65-64.55) vs 55.95 months (95% CI: 50.19-61.71), χ2=12.058, P=0.001］. Compared with the non-sustained virologic response cohort, the sustained virologic response cohort had significantly lower 5-year cumulative incidence rate of HCC than (20.6% vs 34.8%, χ2=5.759, P=0.016) and 5-year cumulative incidence rate of decompensated cirrhosis (5.0% vs 15.2%, χ2=8.239, P=0.004). Virologic response was an independent risk factor for disease progression (hazard ratio=232, 95% CI: 1.45-3.72). ConclusionSustained virologic response can reduce the incidence rates of complications and HCC, improve long-term prognosis, and prolong survival time in patients with compensated hepatitis B cirrhosis.
