ABSTRACT
Objective:To summary the clinical features of 8 cases with ankylosing spondylitis (AS) complicated with systemic lupus erythematosus (SLE).Methods:This study was conducted retrospectively from January 2007 to November 2018. Eight patients with AS complicated with SLE who were admitted to Foshan Hospital of TCM were analyzed. Bath ankylosing spondylitis disease activity index (BASDAI) was compared using t-test. Results:Four patients were female. The mean age was (31±14) years, ranged from 16 to 59 years. The average disease duration of AS was (27±30) months(ranging from 4 to 144 months). The average disease of duration SLE was (69±51) months (ranging from 1 to 80 months). All patients was human lymphocyte antigen (HLA)-B27 positive. SLE-related organ involvement included kidney in 5 cases, leukocytopenia in 8 cases, arthralgia in 6 cases, nervous system in 1 case and skin rash in 3 cases. Renal biopsy were performed in 3 patients. And 2 cases were class Ⅲ+Ⅴ lupus nephritis, another one was class Ⅳ+Ⅴ lupus nephritis.Conclusion:AS may complicated with SLE. Some drugs may be able to active the potential SLE, which should be differentiated from drug-related lupus.
ABSTRACT
Objective To investigate the reliability and validity of the medical outcomes by applying short form-36 (SF-36) in evaluating gout patients’ health related quality of life (HRQOL).Methods Gout patientswere enrolled between March 2016 and June 2016 in Foshan Hospital of Traditional Chinese Medicine.Patients completed the SF-36 questionnaire.Summary scores,physical component summary (PCS) and mental component summary (MCS) were calculated by summing factor-weighted scores across all 8 subscales,with factor weights derived from general population.The indicators of reliability and validity included internal consistency,test-retest reliability,structural and discriminant validity,ceiling and floor effect.Results Totally 306 patients were enrolled.The internal consistency test showed that the Cronbach α coefficients ranged from 0.782 to 0.822,and the test-retest reliability coefficients ranged from 0.720 to 0.986 (P＜0.01).Structural validity analysis showed that there were two items whose eigenvalues were greater than one with the cumulative contribution rate of 66.1％.The discriminant validity analysis found that patients with more numbers of tophi,higher frequency of flare,multi-arthrosis involved and more complications had less scores of PCS and MCS (P＜0.05).There was a high ceiling effect on physiological function and a higher ceiling and floor effect on role limitation and emotional function caused hy impaired physical health.Conclusion The SF-36 can be used for the assessment of HRQOL in Chinese gout patients but disease specific questionnaire are warranted.
ABSTRACT

ABSTRACT
Purpose To evaluate the clinical value of triple-rule-out (TRO) computed tomographic angiography using adaptive prospective ECG triggering for chest pain patients.Materials and Methods Sixty patients with chest pain were prospectively collected and randomly divided into group A and group B:group A (n=30) performed prospectively gated axial scan and group B (n=30) performed retrospectively gated helical scan.The vascular density,noise and muscle density of the vessels including aorta,pulmonary artery,coronary artery between the two groups were measured and analyzed.The vascular density/noise ratio,contrast noise ratio and effective dose (ED) between the two groups were calculated.The image quality and scanning radiation dose were compared between the two groups.Results There was no significant difference in the image quality of aorta,pulmonary artery and coronary artery between group A and group B (P＞0.05).The ED in group A was lower than that in group B [(5.90±2.10) mSv vs (11.31 ± 2.12) mSv,P＜0.01].Conclusion The technique of TRO computed tomographic angiography triggered by adaptive prospective ECG can significantly reduce the radiation dose while ensuring image quality.
ABSTRACT
Objective To explore the application value of CT perfusion imaging for predicting the tiny lymph nodes metastasis and micrometastasis of squamous cell carcinoma in cervix after neoadjuvant chemotherapy.Methods The clinical data and CT perfusion parameters of 46 patients with cervical squamous cell carcinoma who underwent neoadjuvant chemotherapy followed by surgery were enrolled in the study.Based on the surgical pathology findings and short-term follow up,the cases were divided into without tiny lymph nodes metastasis (short axle diameter of lymph nodes＜10 mm) group (n=32) and with tiny lymph nodes metastasis group (n=14).All perfusion data were analyzed retrospectively and the diagnostic value were investigated.Results Blood flow (BF),blood volume (BV) and the maximum diameter of tumor per-chemotherapy in with tiny lymph nodes metastasis group were higher than those in without tiny lymph nodes metastasis group (all P＜0.05).The differences of the maximum diameter of tumor after chemotherapy,permeability,time to peak (TTP) between two groups were not statistically significant (all P＞0.05).Multivariate Logistic regression analysis showed BF and the maximum diameter of tumor per-chemotherapy were independent predictors of the tiny lymph nodes metastasis in cervix after neoadjuvant chemotherapy.ROC showed BF (AUC=0.86,P＜0.001,95％CI [0.75,0.96]) had higher predictive value than maximum diameter of tumor per-chemotherapy (AUC=0.70,P=0.02,95 ％ CI [0.54,0.88]).Conclusion CT perfusion imaging shows the significant predictive value for the tiny lymph nodes metastasis of squamous cell carcinoma in cervix after neoadjuvant chemotherapy.

ABSTRACT
AIM: To determine the utility of the Recognition of Stroke in the Emergency Room (ROSIER) scale as a stroke recognition tool among Chinese patients in the prehospital setting. MATERIALS AND METHODS: Compared with the Cincinnati Prehospital Stroke Scale (CPSS), emergency physicians prospectively used the ROSIER as a stroke recognition tool on suspected patients in the prehospital setting. And, the final discharge diagnosis of stroke or transient ischemic attack made by neurologists, after assessment and review of clinical symptomatology and brain imaging findings, was used as the reference standard for diagnosis in the study. Then, the ROSIER and the CPSS like sensitivity (Se), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV), related coefficient (r) and Kappa value were calculated. RESULTS: In this study, 540 of 582 suspected stroke patients met the study criteria. The CPSS showed a diagnostic Se of 88.77% (95% confidence intervals [CI] 86.11-91.43%), Sp of 68.79% (95% CI 64.88-72.70%), PPV of 87.40% (95% CI 85.97-88.83%), NPV of 71.52% (95% CI 67.71-75.33%) and r of 0.503. Relatively, the ROSIER showed a diagnostic Se of 89.97% (95% CI 87.44-92.64%), Sp of 83.23% (95% CI 80.08-86.38%), PPV of 92.66% (95% CI 90.46-94.86%), NPV of 77.91% (95% CI 74.41-81.41%) and r of 0.584. According to the final discharge diagnosis, both the ROSIER and the CPSS were associated with the final discharge diagnosis (P < 0.05).The Kappa statistic value of the ROSIER and the CPSS were 0.718 and 0.582, respectively. However, there was no statistical significance of the positive rate between the ROSIER and the CPSS in this study (P > 0.05). CONCLUSIONS: The ROSIER is a sensitive and specific stroke recognition tool for health providers' use among Chinese patients in the prehospital setting. However, it cannot be used to confidently rule out or identify stroke as a diagnosis. Comprehensive clinical assessment and further examination on potential stroke patients are still important and cannot be replaced. When it is difficult to objectively complete the ROSIER for patients, the CPSS could replace it in the prehospital setting.
