Purpose To evaluate the combined brain imaging of 11C-CFT and 18F-FDG PET/CT in Parkinson's syndrome,and to test the clinical value of dual tracer combined imaging in differential diagnosis of Parkinson's syndrome.Materials and Methods A retrospective analysis was made on 73 patients with Parkinson's syndrome who underwent 11C-CFT and 18F-FDG PET/CT dual tracer combined brain imaging in the Affiliated Hospital of Guizhou Medical University from January 2016 to February 2021.The patients were divided into Parkinson's disease(PD)group(n=40),multiple system atrophy(MSA)group(n=20),and progressive supranuclear palsy(PSP)group(n=13).Ten normal controls recruited from September to October 2020 were selected as the normal control group.The images were analyzed and summarized,and the caudate nucleus index,putamen index as well as the radioactive uptake cluster values of the corresponding brain regions were compared.Results Compared with the normal control group,all three patient groups showed damage to the dopamine system.PD group showed significant asymmetry,MSA group had more uniform damage,and PSP group had the most severe damage to the dopamine system.In terms of glucose metabolism,the glucose metabolism in the cerebellar hemisphere of MSA group was significantly reduced compared with other groups(P<0.05).Compared with the normal control group,MSA group only had an increase in glucose metabolism in the diseased thalamus,and the difference was statistically significant(P<0.05).There was a statistically significant difference in midbrain glucose metabolism between PSP group and PD group compared with MSA group(P<0.05).In terms of frontal lobe and anterior cingulate cortex,there were significant differences in glucose metabolism between PSP group,normal control group,and PD group on one or both sides of the cerebral cortex(P<0.05).Conclusion Double tracer can make up for the deficiency of single tracer in differential diagnosis,so as to early make accurate diagnosis of Parkinson's syndrome.

Objective: To explore the effect of reducing complication in branched spongiosum repair for hypospadias Duckett surgery. Methods: Retrospective analysis was performed for the clinical data of 140 surgical infants with hypospadias Duckett surgery from January 2016 to April 2018. According to different covering materials on newly formed urethra, the experimental group (68 cases) cut dysplasia, branched spongiosum and lateral Buck′s fascia from tunica albuginea to coronary groove and then sutured over newly formed urethra, and the control group (72 cases) used Dartos fascia or subcutaneous fascia. The operative age, penile curvature, length of urethral defect, operation time, added value of coronary groove before and after operation, maximum urinary flow rate and complication rate of postoperative follow-up were compared between the two groups, and the therapeutic effect was analyzed. Results: There was no statistically significant difference between two groups in operating time[(135±49)min vs.(135±45)min, P=0.580] and the value added of coronary sulcus[(0.1±0.2)cm vs.(0.1±0.1)cm, P=0.167]. In experimental group, there were 8 cases of urethra percutaneous fistula (11.8%) (coronary groove fistula in 3 cases, 4.4%)and 6 cases of urethral stenosis (8.8%) without urethral dehiscence. In control group, there were 18 cases of urethra percutaneous fistula (25.0%)(coronary groove fistula in 11 cases, 15.3%), 10 cases of urethral stenosis (13.9%), and 2 cases of urethral dehiscence (2.8%). The incidence of postoperative urinary fistula and total complications in experimental group was lower than that in the control group, and the difference was statistically significant (P<0.05), while the incidence of urethral stenosis was not statistically different between two groups (P>0.05). The maximum urine flow rate of experimental group at 6 months after surgery was significantly higher than control group[(9.5±3.8)ml/s vs.(6.8±2.8)ml/s], and the difference was statistically significant (P<0.001). Conclusions Urethral cavernosum reconstruction can significantly reduce the incidence of postoperative coronary groove fistula of hypospadias Duckett surgery and improve the postoperative urine flow rate.

Objective To conduct a health check-up intention analysis to understand residents' altitude to health eheck-up. Methods A total of 3600 residents living in Shanghai completed the selfdesigned questionnaire. Results About 35.2% participants received health check-up onee per year. In 36 to 60 or > 60 age group, the figure was increased up to 62.6% or 50. 4%, respectively. Public institution employees and those with medical insurance were found to have the highest rate of health checkup. Conclusion Our investigation results suggest that government leadership,health management model and contents, and personnel training should be improve.

Objective To evaluate the present rehabilitation status of mentally ill patients at community health service centers in Shanghai. Method Investigation on mental disorder network, present prevalence, community disease classification, and cost-effect assessment was conducted in 201 health service centers in Shanghai in 2007. Result Working condition, staff-member constitution, and finical investment were unoptimistic. However, the community health service centers consider the outcomes of community rehabilitation and management were satisfactory. Conclusion It should be necessary to facilitate the development of community mental health service system, achieve various community rehabilitation and health care, and improve social security system of community healthcare providers.
