The department of critical care medicine, the clinical base of critical care medicine, is the centralized management unit for the treatment of critical patients. Medicine and nursing are independent disciplines, but both can be fully utilized from different perspectives when dealing with critically ill patients. With the development of critical care medicine understanding and technology, the concept of doctor-nurse integration construction in the department of critical care medicine has emerged. Doctor-nurse integration construction in the department of critical care medicine needs to take severe diseases as the core and academic development as the orientation. Clinical practice should be carried out through medical cooperation, based on critical cognition and unified thinking mode.

【Objective】 To investigate the anemia status of infants and toddlers aged 6 - 24 months in Linxia Hui Autonomous Prefecture, Gansu Province, and to comprehensively evaluate the differences in feeding behaviors between anaemic and normal children through the infant and child feeding index (ICFI) and feeding knowledge scores, so as to provide reference for the guidance of infants and young children feeding in ethnic minority areas and the promotion of children′s growth and development. 【Methods】 Taking infants and young children aged 6 - 24 months in Linxia Prefecture as the study subjects, a multi-stage random sampling method was used to select children who met the requirements from 5 townships and 5 villages in 7 counties in 2019 and 2020.Periphral blood samples were collected to test the level of hemoglobin, so as to determine the anemia status.Meanwhile, physical examination was performed and a questionnaire survey of guardians was conducted to analyze the association betweenanaemia and feeding patterns 【Results】 A total of 3 901 infants and children were included in this study, of whom 729 (18.70%) were anaemic, with a mean ICFI score of 12.56±2.70 and a mean feeding knowledge score of 1.97±1.01.There was no statistically significant association of low feeding knowledge score and low ICFI with anaemia after adjusting for confounders (P>0.05), Unqualified meat addition in ICFI was a risk factor for anaemia (OR=1.355, P=0.042), while non-bottle feeding in the past 24 hours (OR=0.762, P=0.021), and breastfeeding in the past 24 hours of infants and toddlers aged 12 - 24 months (OR=0.228, P=0.018) were protective factor for anemia in infants and toddlers aged 12 - 24 months. 【Conclusions】 The average prevalence of anemia in infants and toddlers aged 6 - 24 months in Linxia Hui Autonomous Prefecture of Gansu Province is high, but the level of infant feeding and the level of feeding knowledge of caregivers are low.Early adherence to breastfeeding, timely addition of supplementary food, and more comsumpution of meat for children are conducive to preventing anemia.

ObjectiveTo determine the trend in diabetes-related death and probability of premature mortality among residents in Yangpu District of Shanghai and provide evidence for the formulation of relevant intervention strategies. MethodsMortality and demographic data were collected among residents in Yangpu District of Shanghai from 2002 to 2020. Statistical analysis was conducted using chi-square test with SPSS 21.0 and Excel 2010. Joinpoint regression was used to determine annual percent change （APC）. The mortality was standardized by utilizing the world standard population in 2000. ResultsA total of 25 091 cases of diabetes-related deaths were reported in Yangpu District， Shanghai from 2002 to 2020. The average annual crude mortality of diabetes-related diseases was 122.10/10⁵， which was 116.13/10⁵ in males and 128.23/10⁵ in females. The difference between males and females in crude mortality was statistically significant （P<0.05）. Moreover， primary causes of diabetes-related deaths were diabetes， cardiovascular and cerebrovascular diseases， and tumors. Among diabetic deaths， peripheral circulatory complications accounted for 50.79%， followed by renal complications （16.05%）. The crude mortality in males， females， and total of diabetes-related diseases showed an upward trend， while the standardized mortality remained stable with an upward trend in male and a downward trend in female. Furthermore， the crude mortality in males， females， and total of diabetes complicated with cardiovascular and cerebrovascular diseases showed an increasing trend. In contrast， both the standardized mortality in males and in total showed an increasing trend， while that in females remained stable. The overall crude mortality of diabetes was on the rise， which was increasing in males and stable in females. The overall standard mortality of diabetes was on the decline， which was increasing in males while declining in females. In addition， the probability of premature mortality caused by diabetes-related diseases， cardiovascular and cerebrovascular diseases complicated with diabetes， and diabetes decreased from 2002 to 2020 with no statistical significance. Males showed an upward trend while females showed a downward trend. ConclusionThe mortality of diabetes-related diseases， cardiovascular and cerebrovascular diseases complicated with diabetes， and diabetes among residents in Yangpu District of Shanghai is on the rise. Similarly， standardized mortality and probability of premature mortality in males for all three diseases are also on the rise. It warrants more attention to the health of male diabetes patients and targeted measures to reduce the disease burden.

Objective:To investigate the diagnostic value of bronchial arteriography CT (BA-ACT) combined with bronchoscopy (BS) in bronchial Dieulafoy′s disease (BDD), and the role of bronchial artery embolization (BAE) in the treatment of BDD.Methods:Retrospective analysis was made on the clinical data of 5 patients suspected of being BDD treated by BS in Guangzhou First People′s Hospital or Guangzhou Thoracic Hospital from January 2008 to January 2018 due to hemoptysis. Bronchial arteriography (BAG) and BA-ACT were performed during the operation of interventional embolization. BAG rotary acquisition data were post-processed according to BS findings, and BA-ACT reconstruction images of the diseased bronchi and bronchial arteries were obtained. BS reexamination and clinical follow-up observation were carried out after embolization to analyze the effect of embolization.Results:There were one BDD lesion for the five patients respectively, and the BAG lacked characteristic manifestations. Bronchoscopy revealed BDD foci to present as papillary (case 1-case 3), nodular (case 4), or lirellate (case 5) subbronchial submucosal protrusion lesions. On the BA-ACT reconstruction plot, the BDD lesions of papillary, nodular and carination manifested correspondingly as a bronchial artery branches locally " pointed arch" shaped (cases 1-case 4) or " bead-like" (case 5) fold and protruding toward the bronchial lumen. The BDD lesions of the cases 1-case 4 retraction and disappearance after one BAE were observed by BS examination, and no hemoptysis recurrence during the follow-up period (54-91 months). The ridge like BDD lesion of the case 5 remained unchanged after BAE, and hemoptysis recurred at 71 months after the first BAE; the uncollapsed foci were supplied by two collateral vessels that confirmed by second BAG and BA-ACT, and no hemoptysis for 71 months followed up after second BAE.Conclusions:BA-ACT combined with BS enables a locative and qualitative diagnosis of BDD, and BAE is a very effective treatment method for BDD.

In existing vascular interventional surgical robots, it is difficult to accurately detect the delivery force of the catheter/guidewire at the slave side. Aiming to solve this problem, a real-time force detection system was designed for vascular interventional surgical (VIS) robots based on catheter push force. Firstly, the transfer process of catheter operating forces in the slave end of the interventional robot was analyzed and modeled, and the design principle of the catheter operating force detection system was obtained. Secondly, based on the principle of stress and strain, a torque sensor was designed and integrated into the internal transmission shaft of the slave end of the interventional robot, and a data acquisition and processing system was established. Thirdly, an ATI high-precision torque sensor was used to build the experimental platform, and the designed sensor was tested and calibrated. Finally, sensor test experiments under ideal static/dynamic conditions and simulated catheter delivery tests based on actual human computed tomography (CT) data and vascular model were carried out. The results showed that the average relative detection error of the designed sensor system was 1.26% under ideal static conditions and 1.38% under ideal dynamic stability conditions. The system can detect on-line catheter operation force at high precision, which is of great significance towards improving patient safety in interventional robotic surgery.

Objective:To investigate the effects of nedaplatin combined with docetaxel on serum tumor markers and T lymphocyte subsets in patients with epithelial ovarian cancer.Methods:Ninety-two patients with epithelial ovarian cancer who received treatment from March 2016 to December 2017 were included in this study. They were randomly assigned to undergo nedaplatin combined with docetaxel (observation group, n = 46) or cisplatin combined with paclitaxel (control group, n = 46). Both groups received two 21-day courses of treatment. Serum tumor marker level, T lymphocyte subset level, clinical efficacy, incidence of adverse reactions, and 2-year survival rate were compared between the two groups. Results:After treatment, serum cancer antigen 125 (CA125), cancer antigen 199 (CA199), and carcinoembryonic antigen (CEA) levels were (45.84 ± 22.46) U/mL, (35.13 ± 15.03) U/mL, (16.21 ± 3.20) U/mL, respectively in the control group and they were (28.33 ± 20.11) U/mL, (14.82 ± 10.11) U/mL, (5.16 ± 1.33) U/mL, respectively in the observation group. After treatment, CA125, CA199, and CEA levels in each group were significantly decreased compared with before treatment. After treatment, CA125, CA199, and CEA levels were significantly lower in the observation group than in the control group ( t = 3.94, 7.61, 21.63, all P < 0.05). After treatment, the numbers of CD3 +, CD4 +, CD8 + cells in the control group were (16.22 ± 3.12)%, (15.20 ± 1.46)%, (29.21 ± 5.17)%, respectively, and they were (31.22 ± 4.11)%, (24.99 ± 1.71)%, (24.25 ± 4.45)% respectively in the observation group. After treatment, the numbers of CD3 + and CD4 + cells in the observation group were significantly higher than those in the control group ( t = 19.72, 29.53, both P < 0.05). After treatment, the number of CD8 + cells in the observation group was significantly lower than that in the control group ( t = 4.93, P < 0.05). Total response rate was significantly higher in the observation group than in the control group [78.26% (36/46) vs. 58.70% (27/46), χ2 = 4.08, P < 0.05]. The incidence of adverse reactions was significantly lower in the observation group than in the control group [23.91% (11/46) vs. 45.65% (21/46), χ2 = 4.79, P < 0.05]. The 2-year survival rate was significantly higher in the observation group than in the control group [43.48% (20/46) vs. 23.91% (11/46), χ2 = 3.94, P < 0.05]. Conclusion:Nedaplatin combined with docetaxel is highly effective on epithelial ovarian cancer. The combined therapy can greatly reduce serum CA125, CA199, and CEA levels but has no great effects on T lymphocyte subsets. It can increase the survival rate but has no serious adverse reactions.

Objective:To discuss the problems existing in the implementation of the Chinese health industry standard WS 523-2019 by testing SPECT device.Methods:Under the WS 523-2019 standards, a total of 10 SPECT devices were tested with regard to their SPECT reconstructed spatial resolution (SRSR), system planar sensitivity (SPS), system spatial resolution (SSR), whole body system spatial resolution (WSSR), intrinsic uniformity (IU), intrinsic count rate performance (ICR), intrinsic spatial resolution (ISR) and intrinsic spatial linearity(ISL).Result:Under the requirements of WS 523-2019 standards for qualified limits, there are 3 devices with ISL unqualified and the rest of the performances qualified. The new standards basically can meet the clinical requirements and reflected the overall performance of SPECT.Conclusions:The distance between the radiation source and the surface of the detector has great influence on the spatial resolution.In the measurement of ISL, there must be a lead grid separately in the x and y directions. The lead grids with the parallel slits shall be positioned on the detector with the center slit centered on the detector. It is suggested to add rotation center in the new standards.
