Objective To investigate the application value of spiral CT imaging in diagnosing costal cartilage diseases. Methods CT volume scan with 1~7mm layer thinkness and 1~2.5mm layer distance was performed in 28 cases of costal cartilage diseases and 200 cases of controls. All of the original images were processed to form the thin layer reconstruction of low contrast and high contrast, and then the reconstructed images were transmitted to CT 3D work-station to perform the image reconstruction by MPR, MIP and SSD methods. The ability of different image techniques in displaying costal cartilage was compared, and costal cartilage pathological changes were analyzed. Results The CT scanning images of 228 cases could display the costal cartilage after the management of MPR, MIP and SSD, and the images managed with MIP and SSD were better. Among 28 patients with costal cartilage diseases, 13 cases of costal cartilage damage,9 cases of costal cartilage inflammation and 6 cases of costal cartilage malformation were found. Conclusion Spiral CT image could display the costal cartilage perfectly, was a new means of researching costal cartilage morphology in living body, and was the best imaging technique of researching costal cartilage disease without trauma.

Objective To investigate the imaging methods of multi-slice CT(MSCT) in costicartilage and the diagnostic value in the costicartilage injuries. Methods There were 100 cases in normal group and 36 cases in group of chest injuries. All cases were performed in volume scan according to conventional chest scan by SIEMENS Sensation 4 MSCT, then performed in thin slice low and high contrast image reconstructions. After that, all the source images were input into CT 3D workstations,costicartilage were imaged by postprocessing software such as multiplanar reconstructions(MPR), maximum intensity projection(MIP), surface shade display(SSD) and volume rendering technique(VRT). All the pictures were observed and analyzed by two radiologists. Results All postprocessed images that obtained from the MSCT could show the costicartilage clearly. Normal costicartilage displayed uniform density,regular shape and smooth surface;there were 6 injuries in 10 cases with costicartilage injuries,which displayed no uniformity density or cranny in costicartilage and showed cranny in 2 cases. No significant difference of image quality was found among the three imaging modes of MIP、SSD、VRT(?2=1.356, P=0.716). [JP2]Significant differences were found between MPR and other three imaging modes(U_ MIP:MPR=[JP]12.981,U_ SSD:MPR=12.652, U_ VRT:MPR=12.937, P=0.000). Conclusion So far, the MSCT is the best noninvasive imaging method to show the shape of costicartilage, it may be considered as a clinical “gold standard” in the diagnosis of costicartilage injury.

ObjectiveTo survey 0—6 years old disabled children in Guiyang.Methods4 999 children aged 0—6 years old chosen randomly from 9 145 children of 12 blocks were investigated with the disability sampling survey criteria of 1987.ResultsThe rate of disabled children in Guiyang was 1.58%, and was not significantly different compared with that of whole country (1.36%) and other three areas including Siping City (P>0.05),but significantly higher than that of other six districts including Heping district of Tianjin municipality (P<0.05). All kinds of disability found by this survey were separately intellectual disability (0.92%),comprehensive disability (0.28%),limb disability (0.24%),vision disability (0.10%),psychiatric disability (0.03%),and hearing disability (0.02%). Rates of intellectual and vision disabilities were significantly higher than that of whole country ( P>0.05).ConclusionSome diseases are directly relative to occurrence of disability. The poor income of the children family,lower education of his parents and not gotten preschool education were risk factors of disability. The institution based rehabilitation and community based rehabilitation are main rehabilitation forms to disabled children.

OBJECTIVETo analyze the impact of platelet count on the prognosis of stage II-III colorectal cancer receiving adjuvant chemotherapy.
METHODSClinical and follow-up data of 286 patients with stage II-III colorectal cancer receiving adjuvant FOLFOX chemotherapy from March 2003 to October 2011 were analyzed retrospectively. Associations of baseline blood platelet count before chemotherapy and nadir blood platelet count during chemotherapy with relapse and death after adjuvant chemotherapy were analyzed by ROC curve and the optimal cutoff was selected. The association of the blood platelet count and the prognosis was analyzed by Kaplan-Meier and Cox regression model.
RESULTSROC curve showed the baseline blood platelet count was associated with recurrence (AUC=0.588, P=0.034). The optimal cutoff affecting recurrence was 276×10(9)/L. Kaplan-Meier showed those with baseline platelet count >276×10(9)/L receiving adjuvant chemotherapy had worse disease free survival (DFS) than those with baseline platelet count ≤276×10(9)/L, whose 5-year disease free survival(DFS) was 66% and 80% respectively (P=0.013). Cox regression analysis revealed baseline platelet count >276×10(9)/L was an independent unfavorable factor for DFS of adjuvant chemotherapy in colorectal cancer (HR=1.865, 95% CI: 1.108-3.141, P=0.019).
CONCLUSIONColorectal cancer patients receiving adjuvant chemotherapy with baseline platelet count >276×10(9)/L have worse prognosis.

Objective To analyze the distribution of traditional Chinese medicine (TCM) syndromes and characteristics of patients with acute respiratory distress syndrome (ARDS), and to provide reference for further clinical study of ARDS. Methods The clinical data of ARDS patients admitted to the Department of Critical Care Medicine of Affiliated Hospital of Chengdu University of TCM from November 2017 to February 2019 were retrospectively analyzed. The general data (gender and age) and inducing cause of disease, clinical manifestations, intensive care unit (ICU) stay time, total hospitalization time, outcome in ICU, outcome in 28-day follow-up and TCM syndromes were recorded. The different degrees of disease severity, the clinical manifestations and distribution characteristics of TCM syndromes were analyzed. Results A total of 110 patients with ARDS were enrolled, including 2 patients in mild ARDS group, 33 patients in moderate ARDS group and 75 patients in severe ARDS group. In the etiology analysis of ARDS, infection was the commonest cause, including 46 cases of pulmonary infection (41.8%), 27 cases of sepsis (24.5%), 4 cases of abdominal cavity infection (3.6%), 2 case of urinary tract infection (1.9%), and 13 cases had surgical histories (11.8%). The stay in ICU was 9.00 (3.00, 18.00) days and the total hospital stay was 18.00 (10.00, 30.00) days. The mortality in ICU was 32.7% (36/110), and that in 28-day follow-up was 60.0% (66/110). The clinical symptoms of the patients in moderate and severe groups ARDS were mainly dyspnea, cough, fever, sputum, chest tightness, and palpitations, accounting for 75.0% (81/108), 43.5% (47/108), 28.1% (31/108), 26.9% (29/108), 22.2% (24/108) and 25.9% (28/108), respectively. Compared with the ARDS moderate group, the proportions of patients with dyspnea, cough and palpitation in severe ARDS group were significantly higher [80.0% (60/75) vs. 63.6% (21/33), 50.7% (38/75) vs. 27.3% (9/33), 33.3% (25/75) vs. 9.1% (3/33), respectively, all P < 0.05]. The main TCM syndromes were yang deficiency, exuberant heat-toxin, and wind-heat invading lung, accounting for 53.7% (58/108), 28.7% (31/108), and 25.0% (27/108) respectively. The proportion of patients with exuberant heat-toxin syndrome in severe ARDS group was obviously higher than that in the moderate ARDS group [34.7% (26/75) vs. 15.2% (5/33), P < 0.05], while the proportion of patients with wind-heat invading lung syndrome in moderate ARDS group was more than that in the severe ARDS group [42.4% (14/33) vs. 17.3% (13/75), P < 0.05]. Conclusion ARDS is a critical illness with high mortality and various complicated clinical symptoms, the TCM syndromes of ARDS are mainly yang deficiency, exuberant heat-toxin, wind-heat invading lung, and intermingling of deficiency and excess easily leading to collapse syndrome.

Objective To evaluate the present development and status of quality control for intensive care unit (ICU) in Sichuan Provincial traditional Chinese medicine (TCM) hospitals including integrated traditional Chinese and western medicine hospitals and ethnic hospitals, and to provide practical references for improving the service quality of ICU. Methods Supervisory Group of Sichuan Provincial Critical Care Medicine Quality Control Center of TCM was established in September 2018. From September 8th to 17th, 2018, according to the Scoring Criteria of Quality Control and Supervision Project of TCM for Critical Care Medicine, a 10-day quality control professional guidance was hand out to TCM hospitals with independent ICU in Sichuan Province. The service level of different aspects of hospital quality control was evaluated and ranked from equipment and resource support, medical team, service capacity and level, ward quality, completion of critical care core indicators, completion of quality control of TCM, development of new technologies, diagnosis and treatment schemes for dominant diseases. Results There were 52 TCM hospitals across the province that had an ICU. Thirty-three hospitals were third-class (63.5%), while the rest 19 hospitals were second-class (36.5%). Province-level, city-level and county-level hospitals were accounted for 9.6% (5/52), 38.5% (20/52), and 51.9% (27/52), respectively. Average bed ratio of ICU was 1.8%. Doctor-bed and guard-bed ratios were 0.71∶1 and 2.0∶1, respectively. The average annual admission rate of patients and the average daily admission rate of beds were higher, which were basically 1%. Ward quality was high; the incidence of nosocomial infection was controlled below 10%. Compliance rate of septic shock bundle treatment was high. The incidences of ventilator-associated pneumonia (VAP), catheter-related bloodstream infection (CRBSI) and catheter-associated urinary tract infection (CAUTI) were 0.45%, 0.22%, and 0.30%, respectively. Participation rate of TCM was about 83.4%. Average number of new technologies was about 4.4. Average number of disease schemes was about 2.62. Conclusions ICU of Sichuan Provincial TCM hospitals reaches the standard level in service capacity and level, ward quality, critical medicine quality control, and participation rate of TCM treatment. Improvements are required for other prospects, including department scale, medical personnel allocation, new technical development, diagnosis and treatment schemes of dominant diseases.

Objective:
Establish a murine model for hyperuricemia (HU) and periodontitis to explore whether there is correlation between them and provide a basis for periodontal treatment.
Methods:
Fourteen male KM mice were divided into 2 groups; the HU group (n=7) was fed food supplemented with potassium oxonate and uric acid, the NC group (n=7) was fed standard food, and the induction period was 35 days. On the 25th day, the molars on one side were ligated to induce periodontitis (P side), while the opposite was true for the control (C side). Baseline and terminal serum uric acid (UA) levels were detected, and alveolar bone resorption was analyzed by micro-CT.
Results:
The serum UA level of HU mice was (112.94 ± 26.82 )mol/L, that of the NC group was (72.21 ± 19.95) μmol/L, and the difference in UA level was statistically significant (P < 0.05). The P side bone volume fractions of the HU and NC groups were( 29.01 ± 11.09)% and (29.56 ± 15.27)%, respectively, which were not significantly different (t=-0.072, P=0.944). The P side bone mineral densities of the HU and NC groups were(0.53 ± 0.16) g/cm3 and (0.52 ± 0.14) g/cm3, respectively, which were not significantly different (t=0.038, P=0.970). Additionally, there was no correlation between HU or serum UA and alveolar bone resorption (P > 0.05).
Conclusion
This research established a murine model for HU and periodontitis, but based on micro-CT analysis of alveolar bone, no relationship between HU or UA levels and periodontitis was found.
