Objective To explore the structure of violent attitude and the predictive character of the passionate criminal and recidivist. Methods This study used FMMU-Abnormal Personality Risk Factors Inventory (FMMU-APRI) for measuring explicit violent attitude of the passionate criminal and recidivist in prison; while used the picture Attitude Activation paradigm (AAP) for assessing implicit violent attitude. Results The AAP results showed that parts of passionate criminal and recidivist had reversed priming effect, according to whether reversed, there were divided into four types: no-reversal passionate criminals, reversal passionate criminals, no-reversal recidivists and reversal recidivists, VIO scores of no-reversal passionate criminals and recidivists recidivist were significantly higher than the norm, as reversal passionate criminals and recidivists had no significance; in noreversal passionate criminals, compatible response rate was 1.104, incompatible response rate was 1.053; in reversal passionate criminals, compatible response rate was 1.042, incompatible response rate was 0.997; in no-reversal recidivists, compatible response rate was 1.059, incompatible response rate was 1.097; in reversal recidivists , compatible response rate was 1.039, incompatible response rate was 0.998, as each group had strong priming effect, and each group had a dissociation of implicit and explicit violent attitude. Conclusion The results suggest that offenders who have committed a crime in the same category also had a different violent attitude; and integrating indirect methods with direct methods would predict a crime more accurately.

Quorum sensing is an important gene regulatory mechanism in Pseudomonas aeruginosa and controls the expression of numerous virulence factors. We designed and constructed a screening system for quorum-sensing inhibitors. We developed the system by using the lasI and rhlA promoters fused with promoterless sacB as reporters. Using this system we screened a number of Chinese herb extracts, and identified three herb extracts containing inhibitors to the quorum-sensing system and to its regulated genes. The screening system developed was highly efficient and sensitive. It could serve as a useful tool to identify herb compounds that block infections but unlikely render antibiotic resistance in pathogens.

Application of new technical means and methods and in-depth exploration in medical service scenarios, for improving the efficiency and quality of diagnosis and treatment, improving the operation and management level and patient′s medical experience are the goals aimed by smart hospitals. Guangdong Second Provincial General Hospital, based on the technical framework of hospital intelligent twins, was exploring to build an all-scenario smart hospital. The hospital built an intelligent operations center, all-scenario smart wards and a smart security and fire protection integrated management center. These practices promoted the service synergy, provided efficient internet of everything experience, and promoted the integrated linkage management of security and fire protection. The hospital effective resolved such deficiencies as insufficient data connectivity, fragmented application scenarios, limited coverage and poor mobility, hence providing reference for the construction and application of whole-scenario smart hospitals.

Objective:To investigate the effect of treatment of spinal meningioma with microsurgical procedures.Methods:From January 2003 to March 2022, there were 120 patients who had spinal meningioma and treated in the Department of Neurosurgery, The First Affiliated Hospital of Sun Yat-sen University. Their clinical data were retrospectively analysed. Of the 120 patients, there were 90 females and 30 males, aged from 14 to 85 (average, 54) years old. According to McCormick Classification, 29 cases were in grade I, 59 cases were in grade II, 25 cases were in grade III, and 7 cases were in grade IV. They were all underwent microsurgery. Patients were followed up by outpatient service within 3 months after surgery, then reviewed by outpatient visits and telephone interviews. McCormick's classification method and MRI examination were used to analyse the neurological and imaging changes of the patients before and after the surgery.Results:A total of 113 patients had complete resection and 7 had the resection of most part of the spinal meningioma. No infection, cerebrospinal fluid leakage, other complications and death occurred. Three months after surgery, 95 patients achieved the improvement or even completely disappearance of symptoms (such as numbness, pain, limited movement, etc.). There were 23 patients who had the symptoms unchanged as what before the surgery. Two patients had the symptoms worsened after the surgery. At 3 months after surgery, 95 cases (79.2%) improved, 23 cases (19.2%) were stable, and 2 cases (1.6%) aggravated. According to McCormick classification method, 92 cases were in grade Ⅰ, 15 cases were in gradeⅡ, 10 cases were in grade Ⅲ, and 3 cases were in grade Ⅳ. MRI scans showed that the dural sac were well refluxed, and no recurrence was found.Conclusion:Microsurgery is safe and effective for removal of spinal meningioma, with significant improvement in symptoms with fewer complications.

Objective:To investigate the value of pericoronary adipose tissue histogram parameters based on coronary CT angiography (CTA) images for the differentiation of acute coronary syndrome and stable coronary artery disease.Methods:The clinical data and CTA images of 93 patients with coronary CTA examination in Suzhou Kowloon Hospital from 2013 to 2018 were analyzed retrospectively. There were 39 patients with acute coronary syndrome (acute coronary syndrome group) and 54 patients with stable coronary artery disease (stable coronary artery disease group). A region of interest (ROI) was drawn around the stenosis of the coronary arteries, with CT attenuation ranging from-190 to -30 HU to exclude non-adipose tissue. The CT attenuation of ROI excluding non-adipose were measured and histogram analysis was performed. The obtained parameters included the mean value, median value and the 5th, 10th, 45th, 55th, 70th and 95th percentiles. The differences in histogram parameters between the two groups were compared, and then the value of each parameter in differentiating acute coronary syndrome and stable coronary artery disease was evaluated based on receiver operating characteristic (ROC) analysis. The stepwise regression of multivariate logistic regression analysis was used to identify the useful features and establish the final prediction model. The ROC curve of the final model was calculated and its value was analyzed.Results:The mean, median and the 5th, 10th, 45th, 55th,70th and 95th percentile differences between the acute coronary syndrome group and the stable coronary artery disease group were statistically significant (all P<0.05). The ROC curve for the median and the 95th percentile had the same area under curve (AUC) of 0.73. The sensitivity, specificity and AUC of the diagnostic model established by multiple logistic regression were 82.1%, 89.1% and 0.90 respectively. Conclusion:CT attenuation histogram of pericoronary adipose tissue is of high value in differentiating acute coronary syndrome from stable coronary artery disease.
