ABSTRACT
Objective:To explore the diagnostic value of C-TIRADS combined with artificial intelligence-assisted diagnosis S-Detect technology in the differential diagnosis of thyroid nodules.Methods:A total of 237 thyroid nodules patients (237 thyroid nodules)with ultrasound examination and definitive pathologic results in Henan Cancer Hospital from April to September 2020 were retrospectively analyzed. The nodules were diagnosed according to C-TIRADS guidelines, and then by S-Detect technology combined with C-TIRADS guidelines. The ROC curve was plotted with the pathological results as the gold standard, and the area under the ROC curve, sensitivity, specificity and accuracy of the diagnosis results between the two groups were compared.Results:Among the 237 thyroid nodules, 105 were benign and 132 were malignant.The area under the ROC curve of C-TIRADS diagnosis alone and C-TIRADS diagnosis combined with artificial intelligence were 0.869 and 0.942 respectively, the difference between the two groups was statistically significant (χ 2=36.11, P<0.001); When Category 4A was used as the cutoff value of benign and malignant differential diagnosis, the specificity and accuracy of C-TIRADS classification of artificial intelligence-assisted diagnosis was significantly higher than that of C-TIRADS alone, and the difference was statistically significant(83.81% vs 47.62%, 90.72% vs 75.53%, all P<0.05). Conclusions:C-TIRADS combined with artificial intelligence-assisted diagnosis S-Detect technology has a high efficiency in the diagnosis of thyroid nodules and can improve the specificity and accuracy of thyroid nodules diagnosis and reduce unnecessary biopsy.
ABSTRACT
Objective:To investigate the standardized construction of critical care departments in different cities and counties of Guizhou province to promote the homogenization development of critical care medicine in Guizhou Province.Methods:Using research methods such as field investigation and data collection, the public hospitals of 88 counties and urban areas in 9 prefectures and cities of Guizhou province were divided into five routes: southeast, northeast, northwest, southwest, and Guiyang. To design the survey form for the standardized construction of ICU, the e-form was sent to the director of ICU or his/her designated personnel by email or wechat 2-3 days in advance. Check the authenticity of data item by item on site, and leave the hospital after checking the receipt form.Results:From April to July 2021, the survey and research data collection was completed for 146 public hospitals (excluding provincial hospitals) with intensive care departments in 88 counties and cities of 9 dizhou cities in Guizhou Province, including 24 Grade-Ⅲ Level A hospitals. 122 Grade-Ⅱ and above hospitals (including 8 Grade-Ⅲ Level B hospitals, 11 Grade-Ⅲ comprehensive hospitals, 97 Level-Ⅱ A hospitals, 3 Level-Ⅱ B hospitals, and 3 Level-Ⅱ comprehensive hospitals). 146 public hospitals have a total of 80 983 beds and 104 017 open beds. The department of Critical Care has 2 035 beds. The ratio of actual beds in ICU to total beds in hospital was 2.51%. From 1999 to 2010, 18 (12.33%) established departments, and from 2011 to 2021, 128 (87.67%) established departments. The total area of the discipline is 113 355.48 m 2, with an average bed area of 55.70 m 2. There were 97 hospitals with 1.5-2.0 m bed spacing, accounting for 66.44%, and 49 hospitals with 2.1- > 2.5 m spacing, accounting for 33.56%. The number of negative pressure wards: 1 in each of 43 hospitals, accounting for 29.45%; 103 hospitals did not have, accounting for 70.55%. The number of single rooms: 288 in 140 hospitals, accounting for 95.89%; 6 hospitals did not have, accounting for 4.11%. Central oxygen supply: 138 hospitals have (94.52%); 8 hospitals did not have, accounting for 5.48%. Natural ventilation: in 129 hospitals with 88.36%; 17 hospitals did not have, accounting for 11.64%. Specialized ICU construction: 66 hospitals, accounting for 45.21%; none in 80 hospitals, accounting for 54.79%. There are 3 712 doctors and nurses in 146 public hospitals. The total number of doctors was 1 041, and the ratio of doctors to beds was 0.51∶1. The total number of nurses was 2 675, and the ratio of nurses to beds was 1.31∶1. Conclusions:All 88 counties and districts in 9 prefectures and cities of Guizhou province have established intensive care medicine departments. The standardization of the discipline construction has been significantly improved. Lack of talents is still an important factor restricting the rapid development of the discipline.
ABSTRACT
Carbon dioxide (CO 2) ejection syndrome is common after artificial pneumoperitoneum, and it often attracts the attention of anesthesiologists because of its rapid changes in vital signs. CO 2 ejection syndrome is not uncommon in critically ill patients, and may occur after mechanical ventilation in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). There are few relevant reports about CO 2 ejection syndrome, and a considerable number of clinicians have little understanding of the pathological changes. A case of AECOPD patient with CO 2 ejection syndrome after endotracheal intubation was admitted to the intensive care unit (ICU) of the Affiliated Hospital of Guizhou Medical University. After treatment, such as fluid expansion, vasoactive drugs and ventilator assistance, the patient's condition improved and was transferred out of the ICU. It is expected to provide some references by summarizing the diagnosis and treatment of this case and reviewing relevant literature reports.
ABSTRACT
Objective:To discuss the feasibility of offering specialized courses of critical care medicine in undergraduate clinical medicine education, so as to alleviate the shortage of critical care medicine staffs and lay a foundation for improving the success rate for the treatment of critical cases.Methods:The undergraduates majoring in clinical medicine from 2008 to 2011 in Guizhou Medical University (the former Guiyang Medical College) were enrolled. After they had been enrolled in the undergraduate education for 3 years and were ready for Grade four, which meant basic medicine teaching had been completed and clinical medicine teaching was about to start, they were introduced and preached to each discipline, including critical care medicine. The undergraduates were free to choose professional direction of clinical training in Grade four. Students majoring in clinical medicine from 2012 to 2014 were free to choose their major direction when they entered the school.Results:From September 2011 to July 2019, the university had cultivated 246 undergraduates majoring in clinical critical care medicine from 2008 to 2014, and the critical care medicine professional team of affiliated hospital had undertaken 540 teaching hours. By July 2019, all students had graduated on time, with an employment rate of 100%. Forty students took postgraduate programs in our school and other schools, accounting for 16.3%.Conclusions:Professional education of critical care medicine in the undergraduate course of clinical medicine can mobilize students' interest in learning and subjective initiative, which is conducive to career selection. During the clinical training, the students can identify and timely cure critical care cases in the early stage, and partly alleviate the current shortage of critical care medical staffs.
ABSTRACT
Objective To explore the risk factors affecting prognosis of critically ill patients following cardiac surgery, furthermore, to assess severity and keep alarm earlier. Methods A retrospective study was conducted. The clinical data of critically ill patients following cardiac surgery admitted to intensive care unit (ICU) of the Affiliated Hospital of Guizhou Medical University from January 1st 2014 to December 31st 2018 were enrolled. The clinical characteristics, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) and the worst laboratory examination within 24 hours after ICU admission, and the duration of mechanical ventilation, length of ICU stay, using continuous renal replacement therapy (CRRT), accepting vasoactive agents such as norepinephrine, dopamine or dobutamine and blood products such as red blood cells, plasma or platelets were recorded. The patients were divided into survival group and dead group based on discharge prognosis, and the difference in clinical data between the two groups was compared. Binary multivariate Logistic regression analysis was used to screen the risk factors affecting the prognosis of critically ill patients following cardiac surgery, and the receiver operating characteristic (ROC) curve was plotted to analyze the predictive value of these risk factors. Results In total, 97 patients after cardiac operation were admitted to ICU during the five years. Thirty-two patients were excluded owing to age less than 16 years old, no more than 24 hours of the length of ICU stay, without the outcomes of myocardium enzymes or myocardium markers within the first 24 hours or admitted only for pacemaker. Finally, 65 patients met the criteria, with 40 survived and 25 died. Compared with survival group, APACHEⅡ scores, the level of serum uric acid, serum creatinine (SCr), cardiac troponin T (cTnT), brain natriuretic peptide (BNP), procalcitonin (PCT) and the rate of patients accepting CRRT, vasoactive agents and blood products in dead group were significantly increased with significant differences; however, there was no statistically difference in gender, age, body weight index (BMI), distribution of types of cardiac surgery, ratio of patients suffered from hypertension and diabetes, mean arterial pressure (MAP), white blood cell (WBC), coagulation, length of ICU stay, or duration of mechanical ventilation between the two groups. Binary multivariate Logistic regression analysis showed that APACHEⅡ scores [odds ratio (OR) = 1.123, 95% confidence interval (95%CI) = 1.004-1.257, P = 0.043] and cTnT (OR = 1.496, 95%CI = 1.038-2.158, P = 0.031) were the independent risk factors for prognosis of critical ill patients following cardiac surgery. ROC curve analysis showed that APACHEⅡ score and cTnT had predictive value for prognosis of critical ill patients following cardiac surgery, the best was exerted when APACHEⅡ score combined with cTnT, the area under the ROC curve (AUC) was 0.839, the joint prediction probability was 0.42, the sensitivity was 80.0%, and the specificity was 64.0%. Conclusion APACHEⅡscore and cTnT may be one of independent risk factors for prognosis of critical ill patients following cardiac surgery, and there will be far more greater predictive value when APACHEⅡ score combined with cTnT.

Objective To explore the application value of control chart in the management of nosocomial infection in intensive care unit (ICU) by using quality control chart to monitor the infectionsin ICU.Methods From October 2011 to June 2016, ventilator-associated pneumonia (VAP), central line-associated bloodstream infection (CLABSI) and catheter-associated urinary tract infection (CAUTI), namely the three catheters, occurred in ICU of the Affiliated Hospital of Guizhou Medical University were monitored and recorded monthly, then the data was imput into the Excel, and the data was analyzed using SPSS. According to the properties of the data, control chart was derived for monitoring nosocomial infections, finding out problems and for taking actions on time.Results From October 2011 to June 2016, the numbers of new patients in ICU were 23-103 cases per month and the median was 45.00 (39.00, 55.50) cases per month. The numbers of new VAP patients were 0-7 cases per month which median was 3.00 (1.00, 4.00) cases per month and the VAP rates were 0-22.58 cases per 1000 ventilation-days which median was 8.62 (3.28, 12.10) cases per 1000 ventilation-days. The numbers of new CLABSI patients were 0-3 cases per month which median was 0.00 (0.00, 1.00) cases per month and the CLABSI rates were 0-14.82 cases per 1000 catheter-days which median was 0.00 (0.00, 5.38) cases per 1000 catheter-days. The numbers of new CAUTI patients were 0-8 cases per month which median was 1.00 (0.00, 2.00) cases per month and the CAUTI rates were 0-14.06 cases per 1000 catheter-days which median was 3.02 (0.00, 5.86) cases per 1000 catheter-days. 57 points of the three catheter-associated infections incidences were continuously monitored monthly, in which some data points overstepped the warning limit, only 1 CAUTI infection incidence overstepped the control limit, the other monthly three catheter-associated infections incidences were in the control range and had no abnormal arrangement occurred, so all of them were in a controlled state. By using the control chart, the situation of nosocomial infections were analyzed scientifically and intuitively, the existing problems were discussed in time, the improvement programs were made, and the three catheter-associated infections were in a controlled state.Conclusion Control chart has the characteristics of simple operation, intuitive results, and finding problems on time, so it can be used in daily monitoring of nosocomial infection and is worthy of generalization.
ABSTRACT
The lung is a major target organ in acute paraquat (PQ) poisoning, but early PQ-induced severe liver failure is also an important life-threatening situation that can't be neglected. At present, toxin elimination through blood purification is a routine effective therapy recommended at the initial stage of PQ poisoning. However, the mode, therapeutic course and efficacy of blood purification for treatment of liver failure induced by PQ intoxication are still further to be explored. Theoretically, PQ is a substance with small molecule soluble in water, so hemofiltration (HF) is more suitable to be applied for treatment of PQ poisoning, but since PQ itself elimination rate (170 mL/min) from the kidney is far greater than the extracorporeal elimination rate of HF, it is suggested that HF be used only in cases with kidney functional injury caused by PQ poisoning. After PQ intoxication, a great amount of inflammatory mediators are produced; under this circumstance, if continuous veno-venous hemo-filtration (CVVH) is applied, its convection and dispersion features can remove the inflammatory mediators and toxin. Using hemoperfusion (HP) combined with CVVH not only can reduce the concentration of PQ but also can decrease plasma cytokine levels and ameliorate the organ damages. Thus, in cases with hepatic and renal functional damage, the application of combination of HP and CVVH is more effective for the treatment. Bilirubin adsorption can not only reduce bilirubin, but also can decrease PQ concentration, and it is also a means to treat PQ poisoning. In this article, the experience of using CVVH combined with HP, plasma separation and bilirubin adsorption for treatment of 1 case with liver failure induced by PQ poisoning was reported.

Data of the situations in different development stages included the location and area of the ward, the number of beds, the number of physicians and nurses, the structure of academic titles and educational levels, the number of patients admitted to ICU per year, the proportion of patients used ventilator per year, the mortality, the mode of the discipline management, the number of medical postgraduates and undergraduates trained in the ICU, the number of teaching hours, the achievements, the number of research projects, the number of published monographs and papers, the number of the multicenter trials that we participated in, the construction of the team, the personal honor, and so on.Results From 1994 to 2016, the department of ICU had three development stages: the initial development stage of the discipline (from July 1994 to March 2005), the standardization development stage of the discipline (from April 2005 to December 2015), the acceleration development stage of the discipline (from December 2015 to December 2016). The scale of the department expanded from an open unit with 6 beds which was shared with the department of cardiothoracic surgery to 6 enclosed units with 90 beds which were managed independently by the intensivists. The area of thedepartment increased from less than 300 m2 to more than 7000 m2. There were 46 beds in the mixed ICU, which covered an area of 4210 m2. There was only one physician in 1994 while the number of the physicians increased to 19 in 2016. The number of nurses increased from 4 in 1994 to 69 in 2016. The proportion of highly educated talents significantly increased. Furthermore, from 1994 to 2016, the number of beds increased from 6 to 46; the number of patients admitted to ICU per year increased from 138 to 1080; and the number of patients used ventilator increased from 24 to 1057. The mean acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score was > 24.0 at admission, while < 12.6 at discharge. From 1997 to 2016, a total of 79 postgraduates had studied in the department, and 390 teaching hours we had undertaken. From 2011 to 2016, a total of 250 undergraduates had studied in the department, and 540 teaching hours we had undertaken.

ABSTRACT
Objective To investigate the impact of calcification on differential diagnosis of thyroid nodule using shear wave elastography (SWE). Methods One hundred and forty-six patients with thyroid nodules were prospectively enrolled in the study. Ultrasound observations included nodule size, boundary, shape, envelope, internal echotexture, posterior acoustic enhancement, and the relationship with surrounding tissue. According to the presence of internal calciifcation, patients were divided into calciifcation group (groupⅠ) and no calciifcation group (groupⅡ). Real-time shear wave elastography (young′s modulus value) were taken in both groups. Taking surgical pathologic results as the gold standard, receiver operating characteristic (ROC) curve of SWE in diagnosis of benign and malignant thyroid nodule were drawn for two groups respectively. Results In groupⅠ, 25 cases were benign and 38 cases were malignant. The malignant incidence was 60%. Among them the rate of malignant nodules in microcalcification group was 92%(24/26). The incidence of malignant nodules in coarse calcification group was 38%(14/37). The area under the curve (AUC) of SWE in groupⅠwas 0.564. In groupⅡ, 67 cases were benign and malignant had 16 cases. Using 30.43 kPa as the diagnostic point of young′s modulus value, the sensitivity, speciifcity, accuracy and AUC were 93.2%, 81.2%, 84.8%and 0.824. Conclusion In no calciifcation group, SWE is more meaningful in the differential diagnosis of benign and malignant thyroid nodules.
