Objecfive To observe the changes of regional cerebral blood flow (rCBF) in systemic lupus erythematosus (SLE) patients with neuropsychiatrie disorders and evaluate rCBF SPECT imaging in the detection of neuropsychiatric problems in SLE patients.Methods Twenty neuropsychiatrie SLE patients were enrolled in the study and were performed SPECT rCBF imaging anti CT/MRI scans,respectively.Twenty SLE patients without neuropsychiatrie manifestatiuns (SLE) and 20 healthy volunteers also underwent SPECT rCBF imaging as controls.Semiquantitative analysis was conducted as designed by selecting 3 consecutive crosssections and delineating ROI,which generated HQ and the results were compared between with SLE and controls.Results SPECT rCBF findings were almormal in 20 NPSLE.in which 19 of the 20 with abnormal SPECT findings showed focal uptake defects the other patient showed increased foeal uptake.Four N PSLE patients had ahnormal CT/MRI scans findings.Compared with the methods of rCBF and CT/MRI imaging,the difference was significant (P＜0.01).Nineteen SLE patients without neuropsychiatrie manifestations had normal SPECT findings.the other 1 patient showed focal uptake defect.SPECT findings were all normal in 20 healthy volunteers.Temporal cortex was the most commonly involved region,followed by frontal cortex.Specific values generated from semiquantitative analysis (HQ) of temporal and frontal regions in neruopsychiatrie SLE patients were lower than that in SLE patients and healthy volunteers (P＜0.01 and P＜0.05).Conclusion SPECT rCBF imaging has the potential to be a sensitive tool to detect the neuropsyehiatric disordersin SLE patients,and has important value in helping for early diagnosis and therapy.Hypoperfusion on ECD-SPECT under the territory of the middle cerebral artery (MCA) is the most common observation,and which temporal and frontal regions are the most frequently involved regions in neruopsychiatrie SLE patients.

Epidemics of hand, foot and mouth disease (HFMD) have mainly been caused by Coxsackievirus A16 (CVA16) and Enterovirus A 71 (EV-A71), which circulated alternatively or together in the affected area. CVA16 has caused numerous outbreaks and epidemics in multiple countries and geographical regions, and has become an important public health problem. Based on an analysis of the complete VP1 coding region, all CVA16 strains can be divided into genotypes A, B1, and B2. Furthermore, genotype B1 can be divided into subgenotypes B1a, B1b, and B1c. After 2000, no reports of genotype B2 virus strains have been reported. All of the CVA16 strains reported in mainland China have belonged to subgenotypes B1a and B1b. Most CVA16-associated infections cause only mild symptoms; however, some CVA16 infections can lead to severe complications and even death. Vaccination is considered to be the most effective method to control the transmission and infection rate of this virus. A number of research groups are studying various vaccine types, including inactivated vaccines, genetic engineering vaccines, and DNA vaccines, amongst others. In this review, an overview is provided of the research advances in molecular epidemiology and vaccines of CVA16.
