Objective Investigate the operative techniques and early results of a normal thermic and non-cardiopulmonary bypass fashion to perform total thoracoabdominal aortic aneurysm repair (tTAAAR).Methods Between February 2009 and December 2010,41 patients with extensive Crawford Ⅱ thoracoabdominal aortic aneurysm (TAAA) underwent tTAAAR in our hospital.Among them,27 patients underwent tTAAAR in a normal thermic and non-cardiopulmonary bypass fashion.The mean age of this group of patients is (41.85 ± 10.11 ) years ( range 23-61 years),including 18 male and 9 female.The operation was performed via a combined left thoracoabdominal incision.The intercostal incision was through the left fifth (or sixth) intercostal space and an amputated costal arch.The abdominal incision was from the left linea pararectalis to the level of the pubic symphysis via a retroperitoneal approach.The diaphragm was incised circularly to expose the aorta.After the iliac arteries and proximal descending aorta were dissected and exposed sufficiently,two 10 mm side branches were anastomosed to iliac arteries in an end to side fashion.When this was accomplished,the proximal end of the main graft was anastomosed to the proximal descending aorta in an end to end fashion.Then the bypass from descending aorta to bilateral iliac arteries was established under normal thermia.The reestablishment of intercostal arteries and visceral arteries was followed with subsection circulatory arrest.Results The procedure was succeeded in all 27 patients but 1 patient died during operation because of pulmonary hemorrhage.The mean descending aortic circulatory arrest time was ( 13.78 ± 3.77 ) min,the spinal cord ischemia time was ( 19.19 ± 3.93 ) min,and the visceral organs ischemia time was ( 25.19 ± 5.88 ) min,respectively.Mean intubation time is (24.62 ±21.70) hours.Mean ICU stay time is ( 1.84 ± 1.29) days.Two of the 26 survivors suffered permanent spinal cord injury.The morbidity of pulmonary complication,temporal cerebral complications,renal failure,reoperation for hemorrhage,and delayed healing of incision was 11.54%,3.85%,3.85%,3.85%,7.69%,respectively.One Marfan patient suffered Stanford type A aortic dissection after 9 days of tTAAAR.She was rescued by emergency operation.Mean follow-up time was ( 16.04 ± 5.62 ) months,with a follow-up rate of 100%.No late death was found.Conclusion The normal thermic and noncardiopulmonary bypass tTAAAR is a reliable and effective therapeutic strategy for these patients.But the indication of this procedure is limited.If the thoracoabdominal aortic aneurysm grows too huge,the normal thermic tTAAAR cant be performed.So the TAAA patients in China should be treated in their early stage.

Objective:To retrospectively analyze the characteristics and influencing factors of liver function changes in 111 elderly patients with COVID-19 pneumonia.Methods:111 elderly patients with COVID-19 admitted to the Department of Infectious Diseases, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from February 5 to March 3, 2020 were enrolled. According to the severity of disease and liver function condition, they were divided into severe group ( n=40), normal group ( n=71), abnormal liver function group ( n=86) and normal liver function group ( n=25). The indexes related to liver function changes [total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and γ-glutamyl transferase (GGT)] and related influencing factors were analyzed. Results:Among 111 cases, 86 (77.5%) had abnormal liver function of varying degrees, and 28 (25.2%) had liver injury. The abnormal rates of TBil, AST, ALP and GGT were significantly higher in the severe group than normal group ( P<0.05). There were no significant differences in age, ribavirin, glucocorticoid and the application of lopinavir-ritonavir tablets between the abnormal liver function and the normal group ( P>0.05). The proportion of male was significantly higher in the abnormal liver function than normal liver function group ( P<0.05). Conclusion:Elderly COVID-19 patients have a higher proportion of abnormal liver function, and patients in the severe group are more likely to have higher level of TB, AST, ALP and GGT. The abnormal liver function may be related to the direct viral infection of the liver and the inflammatory immune response of the body after infection in elderly patients.

Background::Dual-energy computed tomography (DECT) is purported to accurately distinguish uric acid stones from non-uric acid stones. However, whether DECT can accurately discriminate ammonium urate stones from uric acid stones remains unknown. Therefore, we aimed to explore whether they can be accurately identified by DECT and to develop a radiomics model to assist in distinguishing them.Methods::This research included two steps. For the first purpose to evaluate the accuracy of DECT in the diagnosis of uric acid stones, 178 urolithiasis patients who underwent preoperative DECT between September 2016 and December 2019 were enrolled. For model construction, 93, 40, and 109 eligible urolithiasis patients treated between February 2013 and October 2022 were assigned to the training, internal validation, and external validation sets, respectively. Radiomics features were extracted from non-contrast CT images, and the least absolute shrinkage and selection operator (LASSO) algorithm was used to develop a radiomics signature. Then, a radiomics model incorporating the radiomics signature and clinical predictors was constructed. The performance of the model (discrimination, calibration, and clinical usefulness) was evaluated.Results::When patients with ammonium urate stones were included in the analysis, the accuracy of DECT in the diagnosis of uric acid stones was significantly decreased. Sixty-two percent of ammonium urate stones were mistakenly diagnosed as uric acid stones by DECT. A radiomics model incorporating the radiomics signature, urine pH value, and urine white blood cell count was constructed. The model achieved good calibration and discrimination {area under the receiver operating characteristic curve (AUC; 95% confidence interval [CI]), 0.944 (0.899–0.989)}, which was internally and externally validated with AUCs of 0.895 (95% CI, 0.796–0.995) and 0.870 (95% CI, 0.769–0.972), respectively. Decision curve analysis revealed the clinical usefulness of the model.Conclusions::DECT cannot accurately differentiate ammonium urate stones from uric acid stones. Our proposed radiomics model can serve as a complementary diagnostic tool for distinguishing them in vivo.

Objective:To explore the correlation between intraoperative cooling temperature and postoperative neurological prognosis in aortic arch surgery.Methods:We observed and collected data from 118 patients who underwent open arch replacement surgery by a single surgeon with mild-to-moderate hypothermic circulatory arrest, from January 2017 to December 2020, in Beijing Anzhen Hospital. According to the bladder temperature during the circulation arrest, 118 patients were divided into 3 groups: T1 group[n=39, (25.58±0.64)℃]; T2 group[n=39, (28.21±0.77)℃]; T3 group[n=40, (30.95±0.97)℃]. Clinical data and operative data were analyzed to assess difference between these 3 groups. Analyze the risk factors of postoperative neurological complications, and explore further the correlation between intraoperative core temperature and postoperative neurological prognosis.Results:Among the 118 patients, the average operation, cardiopulmonary bypass (CPB), block, circulatory arrest, and selective cerebral perfusion (SCP) time were 6.64 h, 188.5 min, 104.19 min, 23.93 min, 28.81 min, respectively. The in-hospital death occurred in 8 patients(6.78%), and permanent neurological dysfunction (PND) in 13 patients(11.02%), transient neurological dysfunction (TND) in 25 patients(21.19%). There was no significant difference in the deaths among the three groups. The incidence of TND and PND in the T3 group was significantly reduced ( P=0.042; P=0.045). In addition, the volume of drainage during the first 24 h and the incidence of re-exploration for bleeding had a relatively obvious decreasing trend ( P=0.005; P=0.012). Through multiple regression analysis, under the adjusted model, the core temperature was independently correlated with the incidence of postoperative PND ( OR=0.51; 95% CI: 0.27-0.97; P=0.0389); in group comparison, the relatively higher core temperature was an independent protective factor for postoperative PND ( OR=0.04; 95% CI: 0.00-0.91; P=0.0434). Conclusion:Our research had preliminary proved that in the open arch replacement surgery, mild hypothermia can reduce the incidence of some complications of deep hypothermia, at the same time improve the prognosis of the neurological prognosis, reduce the incidence of postoperative PND.

Taohe Chengqitang is a classical prescription published in The Catalogue of Ancient Classic Recipes (The First Batch). This study systematically summarized traditional Chinese medicine (TCM) ancient books and modern clinical reports on Taohe Chengqitang and investigated its origin, composition, basis, and historical evolution in processing requirements, dosage, preparation and administration, and functions. The findings indicated different opinions on drug basis, preparation of decoction pieces, and drug dosage conversion. Based on sufficient literature review, the actual development needs of classical prescriptions, and the usage habits of modern clinical practice, this study recommended dried mature seeds of Prunus persica or P. davidiana for Persicae Semen, dried twigs of Cinnamomum cassia for Cinnamomi Ramulus, honey-fried Glycyrrhiza uralensis for Glycyrrhizae Radix et Rhizoma, raw Rheum palmatum, R. tanguticum, or R. offìcinale for Rhei Radix et Rhizoma, and mirabilite for Natrii Sulfas. In terms of drug dosage, the doses directed converted from weights and measures in the Han dynasty were large. According to the common doses in modern clinical practice, conversion was carried out based on 6 g of Cinnamomi Ramulus, 6 g of Natrii Sulfas, 6 g of Glycyrrhizae Radix et Rhizoma, and 12 g of Rhei Radix et Rhizoma. The weight of Persicae Semen should be determined according to the actual measurement. In terms of preparation and administration, the drugs in the pot were decocted with 1 400 mL of water to obtain 500 mL of decoction, which was filtered and slightly boiled in the presence of Natrii Sulfas. About 100 mL of warm decoction was taken before meals, three times a day. It was recorded in the ancient books that Taohe Chengqitang was indicated for the syndromes of heat invading the bladder and accumulating inside in the case of released exterior syndrome in Taiyang. After symptom-based flexible application by doctors, it is currently commonly used in the treatment of diabetic nephropathy, constipation, chronic renal failure, and other diseases.
