Severe acute respiratory syndrome is an infectious disease caused by a new type of coronavirus. It belongs to the seasonal febrile diseases in traditional Chinese medicine. The prevention and treatment of severe acute respiratory syndrome (SARS) can be under the guidance of the doctrines for treating febrile diseases of traditional Chinese medicine, treatment based on syndrome differentiation, such as syndrome differentiation of triple energizer, syndrome differentiation according to defensive phase, qi phase, nutrient phase and blood phase. During April and May of 2003, 8 cases of SARS were diagnosed in Shanghai, and 6 patients accepted complementary therapy of traditional Chinese medicine, without death case. The only one patient who didn't take glucocorticoid therapy was complementarily treated with traditional Chinese herbs through the whole treating procedure. Upon the successful treatment of the eight cases of SARS in Shanghai, it is demonstrated that the triple-energizer syndrome differentiation and defensive-qi-nutrient-blood syndrome differentiation in traditional Chinese medicine are of high value in treating SARS patients.

To explore the application value of low-dose CT in lung cancer after operation in a short-term review by comparing conventional and low-dose CT. Methods:In 83 cases of lung cancer during the immediate postoperative period review, 50 cases (group A) underwent conventional CT scanning, whereas 33 cases (group B) underwent low-dose CT scanning. All CT scans were scored on the basis of image quality and clinical needs. The radiation dose indexes CTDIvol and DLP were recorded for each case. A comparison of the score and radiation dose between the two groups helped determine the existence of significant differences. Results:The average image quality scores of the two groups were 3.705±0.314 and 3.311±0.442, those for clinical demand were 2.670±0.373 and 2.561±0.410, those for CTDIvol were (19.248±1.532) mGy and (10.138±1.113) mGy, and those for DLP were (170.180±19.259) mGy*cm and (99.061±14.504) mGy*cm. The two groups exhibited significant differences in image quality, CTDIvol, and DLP but revealed no significant dissimilarity in clinical demand. Conclusion:Low-dose CT completely meets the clinical requirements for short-term follow-up after resection of lung cancer and significant reduction in radiation dose.

Objective To investigate the effects of miR-10a expression on migration and invasion of human pancreatic cancer cells AsPC-1.Methods Small interfering RNA targeting at miR-10a (miR-10a-siRNA) was constructed,then it was transfected into pancreatic cancer AsPC-1 cells,and nonsense siRNA (Nc-siRNA) group and blank control group was established.Real time PCR assay was used to detect the expression of miR-10a in the 3 groups,and wound healing assay and Transwell assay were used to determine the migration and invasion abilities of cancer cells.The amount of matrix metalloproteinase-13 (MMP-13) in supernatant of cancer cell culture of each group was examined by ELISA assay.Results The miR-10a levels in control group,NC-siRNA group and miR-10a-siRNA group were 1.05 ±0.08,1.03 ±0.06,0.02 ±0.01 ; and the number of transmembrane cell were (150 ± 2.6),(145 ± 2.2),(62 ± 1.8),the levels of MMP-13 in the supernatant were (108.5 ± 2.8),(107.8 ± 2.5),(35.8 ± 1.5) pg/ml.The values were significantly lower in miR-10a-siRNA group than those in control group and NC-siRNA group (P ＜ 0.01).The distance of cultured clone in miR-10a treated cancer cells (736± 18 μm) was significantly longer than those in the controls (385 ±5 μm) and NC-siRNA group (395± 13 μm,P＜0.01).Conclusions Down-regulation of miR-10a by siRNA may inhibit migration and invasion of pancreatic cancer AsPC-1 cells,and the downregulated expression of MMP-13 may be one of the important mechanisms.

Objective To investigate the effects of environmental hypothermia on hemodynamics and oxygen metabolism in unanesthetized swine model of hemorrhagic shock.Methods A total of 16 Bama pigs provided by animal experiment centre of the General Hospital of Shenyang Military Command were randomized into two groups ( n =8,each):ambient temperature (A) and hypothermia ( H ).Venous blood (30 mL/kg) was continously withdrawn over 15 minutes to establish hemorrhagic shock model.Core temperature,heart rate,mean arterial pressure,central venous pressure,cardiac output,saturation of mixed venous blood and blood gas analysis were recorded at the baseline and different hemorrhagic shock time.DO2I and VO2I,and the O2 extraction ratio (O2ER) were calculated.Results Core body temperature in group A decreased slightly after hemorrhagic shock model had established and environmental hypothermia resulted in more reduction in core body temperature.The mortality rate was significantly higher in group H (50％) than in group A (0％) (P ＜0.05).DO2I and VO2I decreased significantly after hemorrhage.No difference was found in hemodynamics,DO2I and VO2I between group A and group H,but the difference of pH,lactic acid and O2ER were significant between the two groups (P ＜ 0.05 ).conclusions Environmental hypothermia aggravated the disorder of oxygen metabolism after hemorrhagic shock,which was associated with poor prognosis.

Objective:To compare the diagnostic efficacy of Chinese diagnostic model, the 1990 American College of Rheumatology (ACR) classification criteria and the 2018 ACR new classification criteria (draft) for Takayasu arteritis (TA).Methods:A total of 196 TA patients who came to our hospital from January 1, 2009 to May 31, 2019 in the TA database of the department of rheumatology and immunology, Zhongshan Hospital, Fudan University and 131 patients with other vascular diseases visited during the same period were selected. General characteristics, clinical data, laboratory tests and imaging tests of all patients were collected. Categorical variables were presented as numbers and percentages, between-group differences were analyzed using the χ2 test. Continuous variables were presented as the Mean± SD for a normal distribution or median and interquartile range (IQR) for a non-normal distribution. Between-group differences were analyzed using the Student's t-test or Mann- Whitney test, as appropriate. The sensitivity, specificity, positive predictive value, negative predictive value, accuracy and receiver operating characteristics of the above diagnostic/classification criteria area under the curve were analyzed. P<0.05 was considered significant. Results:In terms of sensitivity, specificity, accuracy, positive predictive value, negative predictive value, and area under receiver operating characteristic curve (ROC), Chinese diagnostic models was 85.7%, 96.2%, 89.9%, 97.1%, 81.5%, 0.909, 1990 ACR criteria was 47.4%, 97.7%, 67.6%, 96.9%, 55.4%, 0.726, 2018 ACR classification criteria was 79.1%, 98.5%, 86.5%, 98.7%, 75.9%, 0.888. The difference between the Chinese diagnostic model and the 2018 ACR criteria in AUC was not statistically significant ( Z=1.186 , P>0.05). The sensitivity, accuracy and diagnostic efficiency of Chinese diagnostic model was the best, that of the 1990 ACR classification criteria was the worst, and the specificity of the 2018 ACR classification criteria was the highest. The Kappa value of the 2018 ACR classification criteria and the Chinese diagnostic model was 0.719, which had good consistency, and the Kappa value of the consistency between the 1990 ACR classification criteria and the Chinese TA diagnostic model was 0.516. Conclusion:The Chinese diagnostic model, which is based on the clinical characteristics of the Chinese TA population, has a good diagnostic efficacy for the Chinese population. The 2018 ACR classification criteria (draft) is highly consistent with the Chinese TA diagnostic model, and can be promoted and applied in practice.
