Objective To study the clinical manifestations and influencing prognostic factors of children with acute paraquat in-toxication ,and to search for reasonable and effective treatments .Methods Retrospectively analyzed the clinical data of 68 children with acute paraquat intoxication from March 2005 to June 2012 .According to the amount of toxic dose and clinical symptoms ,all of them were divided into 3 groups ,mild type(22 cases) ,severe type(26 cases) and fulminant type(14 cases) ,retrospective analysis on clinical manifestation ,auxiliary examination and prognosis among the groups and following up the survival of these patients ,the risk factors which may affect the prognosis were explored .Results 66 cases were poisoned by taking orally and the other 2 cases were poisoned by the skin absorption .Gastrointestinal symptoms were the most common .Among 68 cases ,6 cases was lost the following up ,20 cases died(32 .26% mortality):all children from mild type survived ;8 patients from severe type and 12 patients from fulmi-nant type(30 .77% ,85 .71% ,mortality respectively ) .As the degree of the clinical classification deteriorated ,the mortality in-creased ,there was statistical signification between each other and so did the blood urea nitrogen and serum creatinine (P<0 .05) .By following up ,children who once passed the acute stage can recovery and the pulmonary fibrosis might be reversed by the chest CT follow-up .The logistic regression analysis indicated that children who had been diagnosed with acute kidney injury and multiple or-gan dysfunction syndrome showed the worse prognosis .Conclusion Acute kidney injury is a very important factor for the short term prognosis of paraquat intoxication ,while pulmonary fibrosis determine the long-term outcomes ,lung injury may be reversed in the course of the disease ,so we should take active treatments .

Objectives To investigate the recurrence risk factors and the protective factors of aortic dissection (AD) DeBakey type Ⅲ. Methods 43 patients with AD DeBakey type Ⅲ who were in Guangdong General Hospital from May 2014 to September 2014, were enrolled as the case group, while 27 volunteers exclude AD as the control group. Blood chemistries and other information obtained immediately after admissions , χ2 test or T test was used for univariate analysis of independent samples. Multivariate Logistic regression analysis was used to screen patients with recurrence risk factors or protective factors. Results The prevalence of hypertension (93.02%vs. 18.52%, P = 0.000) and proportion of smokers (34.88% vs. 11.11%, P = 0.027) were significantly higher in case group than control group. Logistic regression analysis showed that hypertension (OR=5.148, 95%CI= [2.209~13.058], P=0.001) and albumin level (OR=0.709, 95%CI = [0.541~0.929], P=0.013) were significantly associated with recurrence of aortic dissection DeBakey type Ⅲ. Conclusion Hypertension is an independent risk factor for recurrence of aortic dissection DeBakey type Ⅲ, and albumin level is a protective factor.

Objective:To investigate the distribution patterns of TCM syndrome elements and syndrome types in cancer-related fatigue (CRF).Methods:A cross-sectional survey was conducted on tumor patients attending the outpatient clinic and wards of the Department of Oncology, Xiyuan Hospital of China Academy of Chinese Medical Sciences from January to December 2021. Descriptive analysis was used to compare the distribution difference of TCM syndrome elements, symptoms and tongue symptoms of CRF and non-CRF patients. The TCM symptoms of CRF were clustered to summarize the common TCM syndromes of CRF.Results:A total of 306 tumor patients were finally included, of which 229 (75%) were CRF and 77 (25%) were non-CRF. Qi deficiency, blood deficiency, and cold-dampness were the most common deficiency and excess syndrome elements in CRF, and liver deficiency, yin deficiency, and blood stasis syndrome elements occurred more frequently in non-CRF than in CRF. TCM symptoms with a frequency greater than 50% in CRF patients, from high to low, were: fatigue > shortness of breath > insomnia or dreaminess > mental fatigue > forgetfulness>lazy speech > impatience, irritability, depression with sighing. The most frequent tongue symptoms, tongue coating, and pulse symptoms were respectively pale tongue, white and greasy coating or smooth white, and pulse deficiency. The symptoms with greater than 30% frequency in 77 non-CRF patients were, from highest to lowest: impatience and irritability or depression with sighing > insomnia or dreaminess > shortness of breath > dry mouth and throat > lumbar spine pain (excluding traumatic) > numbness of limbs > forgetfulness. The highest-ranked tongue, tongue coating, and pulse symptoms were pale tongue, red tongue or less coating, no coating, and thin pulse, respectively. Through clustering analysis, six common syndromes of CRF were obtained, including qi and blood deficiency syndrome, heart and liver blood deficiency syndrome, kidney yang deficiency syndrome, qi and yin deficiency syndrome, spleen deficiency and qi stagnation syndrome, and cold dampness and spleen stagnation syndrome.Conclusions:CRF is a common symptom of different types of tumors. Generally, deficiency syndrome is the main symptom. Qi deficiency and blood deficiency are the common syndrome elements. Common symptoms of high frequency and tongue and pulse are fatigue, shortness of breath, mental fatigue, forgetfulness, pale tongue and thin pulse. The common TCM syndrome types can be preliminarily summarized into 6 types: qi and blood deficiency syndrome, heart and liver blood deficiency syndrome, kidney yang deficiency syndrome, qi and yin deficiency syndrome, spleen deficiency and qi stagnation syndrome, cold dampness and spleen stagnation syndrome.

Objective To analyze the status of hepatitis B and BCG vaccination in children with special health status, and analyze the reasons for the delay of vaccination, so as to improve the timely vaccination rate. Methods A total of 1 129 children with special health status who were registered and vaccinated in our hospital from September 1, 2018 to January 23, 2020 were selected. All children were classified according to the major diseases based on the discharge records. The first injection time of hepatitis B and BCG vaccine was extracted, and the children were divided into different groups based on the number of people who delayed vaccination. The comparison between groups was performed by χ² test. Results A total of 87 children without hepatitis B vaccination and 85 children without BCG vaccination were immediately vaccinated in our hospital after the establishment of the archives in our hospital. None of the 1 129 children with special health status had serious adverse reactions after vaccination. The most common diseases in the delayed hepatitis B vaccination children were premature infants, cardiovascular diseases, and nervous system diseases. The most common diseases in the delayed BCG vaccination children were premature infants, cardiovascular diseases, and neonatal disease. There was a significant difference between the number of delayed hepatitis B vaccination and the number of delayed BCG vaccination, with the number of delayed BCG vaccination being more (χ²=278.24, P<0.00). Conclusion Delayed vaccinations are common in children with special health status. Normal vaccination does not increase the incidence of adverse reactions in children with special health status. Medical staff’s understanding of diseases, types of diseases, and types of vaccines are important factors affecting the vaccination of children with special health conditions. Support from social environment, the understanding and cooperation from children's parents and guardians, and the understanding of medical workers on vaccines and diseases are the keys to truly improve the vaccination rate of children..

Objective To study the benefit of prophylactic antibiotics (PA) in totally percutaneous aortic endovascular repair (PEVAR) in the catheterization laboratory for reducing stent-graft infection and postimplantation syndrome (PIS). Methods The clinical data were analyzed of patients undergoing thoracic endovascular aortic repairs. The patients were divided into non-PA group and PA group according to the use of prophylactic antibiotics before PEVAR. The diagnosis of infection was made by two senior physicians with reference to Hospital Acquired Infection Diagnostic Criteria Assessment released by the Ministry of Health of China. Results The 95 enrolled patients included 35 with PA and 60 without PA group, who were comparable for baseline characteristics. Infection-related deaths occurred in 1 case in non-PA group and retrograde Stanford type A dissection and death occurred in 1 case in PA group (1.67%vs 2.85%, P=1.00). The PA and non-PA groups showed no significant difference in the incidence of postoperative infection (5%vs 2.86%, P=1.000), hospital stay (9.30±7.21 vs 10.06±5.69, P=0.094), infection-related mortality (1.67% vs 0%, P=1.00), or postoperative fever (70.90% vs 91.43%, P=0.20). The body temperature showed significant variations at different time points after procedure (F=19.831, P<0.001) irrelevant to the use of prophylactic antibiotics (F=0.978, P=0.326). Conclusion The current data do not support the benefit of PA in reducing postoperative infection and PIS in patients undergoing PEVAR, but the patients without PA may have worse clinical outcomes in the event of postoperative infections.

BACKGROUNDThoracic endovascular aortic repair (TEVAR) is an emerging treatment modality, which has been rapidly embraced by clinicians treating thoracic aortic disease. However, the clinical manifestations of systemic inflammatory response after TEVAR as post-implantation syndrome (PIS) resemble the perioperative infection. This study aimed to evaluate changes and diagnostic value of procalcitonin (PCT) and other traditional inflammatory markers for infections after TEVAR.

METHODSWe conducted a prospective clinical study that enrolled 162 consecutive aortic dissection cases, who underwent TEVAR in our institution between July 2011 and November 2012. The PCT, C-response protein (CRP), erythrocyte sedimentation rate (ESR) and blood routine examination were monitored before the operation and on days 1, 2, 3 and 5 after the operation. The diagnosis of infection was confirmed by the infection control committee with reference to Hospital Acquired Infection Diagnostic Criteria Assessment, released by the Ministry of Health of the People's Republic of China.

RESULTSPost endovascular repair of thoracic aorta, PCT changes significantly at different time points (χ(2) = 13.225, P = 0.021), without significant difference between the PIS group and the control group (0.24 ± 0.04 vs.0.26 ± 0.10, P = 0.804). PCT values were significantly higher in the first day after TEVAR than the preoperative levels (0.18 ± 0.03 vs. 0.11 ± 0.02, P < 0.001). Compared with PIS patients, the level of PCT, CRP, White blood cell (WBC) and neutrophil (NEU) in the infection patients elevated significantly (relatively χ(2) = 6.062, P = 0.048; χ(2) = 6.081, P = 0.048; χ(2) = 11.030, P = 0.004; χ(2) = 14.632, P = 0.001). According to the ROC analysis, the PCT levels in the first day after TEVAR (AUC = 0.785, P = 0.012) had better predictive values of infection than WBC, NEU CRP and ESR (AUC = 0.720, P = 0.040; AUC = 0.715, P = 0.045; AUC = 0.663, P = 0.274; AUC = 0.502, P = 0.991). The best predictive index was the changes of PCT between preoperative and postoperative (PCT), which possess AUC as 0.803 (P = 0.014). And PCT = 0.055 could be considered as an infection diagnosis cutoff value with a sensitivity of 83.3% and specificity 69.0%.

CONCLUSIONSPCT provides better diagnostic value of infection compared with other inflammatory markers. The potential applications of PCT in differential diagnosis of PIS and infection after percutaneous TEVAR deserve further studies.
