RESUMO

Objective:To explore the feasibility, efficacy and limitation of robot-assisted laparoscopic surgery in the treatment of adrenal tumors in children.Methods:The clinical data of 5 children with adrenal tumors treated with robot-assisted laparoscopic surgery in Wuhan Children′s Hospital, Tongji Medical College, Huazhong University of Science & Technology from October 2020 to March 2021 were retrospectively analyzed. All patients were males aged between 2 years and 4 months to 13 years and 1 month (median: 7 years and 7 months). One case had left adrenal adenomas and 4 cases had right adrenal adenomas.The maximum diameter of tumors was 3.0-6.0 cm (median: 4.8 cm).Results:Robot-assisted laparoscopic adrenalectomy was performed successfully on all 5 patients.The ope-ration time was 215-325 min (median: 275 min). The intraoperative bleeding was 10-50 mL (median: 28 mL). The indwelling time of the drainage tube after surgery was 3-5 days (median: 4 days). The postoperative hospital stay was 9-13 days (median: 11 days). The hospitalization cost was 51 268-58 157 yuan (median: 53 485 yuan). No complications occurred during or after the operation.Postoperative pathological tests suggested adrenal cortex adenocarcinoma in 1 case, pheochromocytoma in 1 case, gangliocytoma in 2 cases, and ganglioneuroblastoma in 1 case.Conclusions:Robot-assisted laparoscopic surgery is safe and feasible in children with adrenal tumors, but there are some limitations.This approach needs to be verified by further clinical research.

RESUMO

Objective:To evaluate the effect of remifentanil on mitogen-activated protein kinase (MAPK) signaling pathway during intestinal epithelial cell apoptosis induced by intestinal ischemia-reperfusion (I/R) in rats.Methods:Thirty-six clean grade healthy adult male Sprague-Dawley rats, weighing 200-250 g, aged 2 months, were divided into 3 groups ( n=12 each) by a random number table method: sham operation group (Sham group), intestinal I/R group (I/R group) and remifentanil group (R group). Intestinal I/R was produced by occlusion of superior mesenteric artery for 1 h followed by reperfusion in anesthetized rats.At 30 min before ischemia, 0.2 μg·kg -1·min -1 of remifentanil was infused intravenously for 5 min , followed by infusion of normal saline for 5 min, repeating for 3 cycles in group R. At 2 h of reperfusion, blood samples were collected from right ventricle to measure the concentration of diamine oxidase (DAO). The animals were then sacrificed and the intestinal tissues were obtained for examination of pathological changes and scored according to Chiu, for calculation of intestinal epithelial cell apoptosis rate (by TUNEL), for determination of the expression of phosphorylated extracellular signal-regulated kinase (p-ERK), phosphorylated c-Jun N-terminal kinase (p-JNK), phosphorylated p38 MAPK (p-p38 MAPK), cleaved caspase-3 and nuclear factor kappa B p65 (NF-κB p65) in nucleoprotein and for calculation of p-ERK/ERK ratio, p-JNK/JNK ratio and p-p38 MAPK/p38 MAPK ratio in the intestinal tissues. Results:Compared with group Sham, Chiu′s scores, serum DAO concentration, apoptosis rate, p-ERK/ERK ratio, p-JNK/JNK ratio and p-p38 MAPK/p38 MAPK ratio and the expression of cleaved caspase-3 and NF-κB p65 in the intestinal tissues were significantly increased in group I/R, and Chiu′s scores was increased ( P<0.05), and no significant change was found in serum DAO concentration, apoptosis rate, p-ERK/ERK ratio, p-JNK/JNK ratio, p-p38 MAPK/p38 MAPK ratio and the expression of cleaved caspase-3 and NF-κB p65 in the intestinal tissues in group R ( P>0.05). Compared with group I/R, Chiu′s scores, apoptosis rate, serum DAO concentration, p-ERK/ERK ratio and expression of cleaved caspase-3 and NF-κB p65 were significantly decreased in group R ( P<0.05). Conclusion:The mechanism by which remifentanil inhibits intestinal epithelial cell apoptosis induced by intestinal I/R is related to promoting activation of ERK in rats.

RESUMO

Protein-protein interactions (PPI) are involved in a variety of biological processes, including cell-to-cell interactions, metabolism and development control. The misregulation, post-translational modification and interference of PPI are related to a variety of human diseases, making the regulation of these interactions a very attractive field of drug discovery. In recent years, the interaction between MDM2 and p53 has become a research hotspot, which plays an important role in the treatment of tumors. But unfortunately there are no such inhibitors approved all over the world. In this view, recent advances of MDM2-p53 inhibitors were briefly described and its inhibitors with potential therapeutic activities in clinical studies were introduced.

RESUMO

OBJECTIVE: To analyze the correlation between occupational stress and hypertension in steel production workers.METHODS: By the stratified cluster sampling method,1 580 steel production workers from an iron and steel group company were selected as study subjects. Occupational stress was measured by the Chinese version of Job Content Questionnaire.The identification of having occupational stress was the ratio of job requirement dimension score over job self-decision dimension score turned to be ≥1. 00. The steel production workers' blood pressure was measured by the updated mercury sphygmomanometer. The effect of occupational stress on blood pressure in steel production workers was analyzed. RESULTS: The dimension score of job self-decision in hypertension group was lower than that in non-hypertension group [20( 16,23) vs 20( 17,24) scores,P < 0. 05]. There was no statistical significant difference in occupational stress ratio,job requirement and social support dimension scores between two groups( P > 0. 05). The multiple logistic regression analysis showed that job self-decision and social support scores were negatively correlated with the incidence of hypertension [odds ratios( 95% confidence intervals) were 0. 68( 0. 51,0. 90) and 0. 54( 0. 45,0. 76),P < 0. 01]. CONCLUSION: Job selfdecision and social support are the influencing factors of the incidence of hypertension in steel production workers. The correlation among occupational stress,job requirement and hypertension are not found in steel production workers.

RESUMO

OBJECTIVE@#To summarize the subtle anatomical structures of the normal nasal bone in multi-slice spiral CT (MSCT) image through the observation of the three-dimensional images.@*METHODS@#One hundred and twenty volunteers who had no nasal trauma and disease history were collected. The nasal was scanned using MSCT. Raw data was reconstructed into bone window images (slice thickness 0.6 mm, slice interval 0.5 mm), and then the images were imported into Syngo Imaging XS software to reconstruct three-dimensional images and to summarize the nasal bone's subtle anatomical structures.@*RESULTS@#The subtle anatomy of normal nasal bone generally included four seams, two holes and one edge. The four seams were left and right nasal-maxillary suture, nasal-frontal seam, and internasal suture. The two holes were left and right nasal aperture. The edge of the nasal was the lower edge of the nasal bone. In addition, there was suture bone in internasal suture in some normal nose. The nasal aperture mostly was hole-like, but some nasal apertures were line shape. The nasal edge can be divided into flat type, wave-shaped type, inverted spike type, hook-shaped type and others.@*CONCLUSION@#The anatomy diversity and individual differences in nasal bone are large. MSCT and three-dimensional image reconstruction techniques, combined with the history of trauma could distinguish between the normal anatomy and fractures.

RESUMO

OBJECTIVE@#To access application value of multi-slice spiral computed tomography (MSCT) and coronary artery calcium scoring (CACS) in investigation the coronary artery disease (CAD), and to explore the effective way of virtual autopsy to evaluate the sudden death due to CAD.@*METHODS@#Nine cases of sudden cardiac death were collected to analyze MSCT before the autopsy. The quantitative analysis of the degree of coronary artery calcium was made by Agatston's method. The CACS of all the subjects were calculated based on the diagnostic criteria for CAD, in which calcium scoring was more than 400. The results of CACS were compared with that of the autopsy.@*RESULTS@#Only 2 cases got the high calcium scoring which were more than 400 in the 9 cases died of CAD confirmed by the autopsy. The prediction rate of CACS for CAD was only 22.2%. Pulmonary edema of different severity was found in both autopsy and MSCT. There was a higher morbidity rate in the left anterior descending of coronary artery than the other branches.@*CONCLUSION@#Obvious calcification of coronary artery can be detected by MSCT and calculating CACS. To detect subtle calcification needs other technologies such as postmortem angiography.

RESUMO

It is practical value for determination the teenagers whether the age is full of the legal responsibility age of 18 years old or not by estimating skeletal age of sternal end of clavicle. The traditional methods mainly based on X-ray radiography. However, sternal end of clavicle and adjacent lung, bronchus, sternum, rib, transverse process of thoracic vertebra are overlapped each other. As a result of overlapping, there will be obtained false negative or positive film reading results when according to X-ray observation of epiphyseal growth of sternal end of clavicle, which directly affect the scientificalness and accuracy of estimating of skeletal age. In recent years, the scholars at home and abroad have started to use thin layer CT scan technology to estimate skeletal age of the sternal end of clavicle. With the 2D and 3D CT recombination technology, the accuracy of the film reading distinctly improves by making the shape, size and position of epiphysis displayed clearly. This article reviews the application and research progress of thin layer CT scanning technology in estimating skeletal age of sternal end of clavicle at home and abroad, analyzes the superiority and value of thin layer CT scan technology, which applied to skeletal age of sternal end of clavicle.

RESUMO

It is never an easy thing to diagnose heart vascular disease only depending on the unenhanced postmortem computed tomography (PMCT). This article reported a case of sudden natural death after the complaint of anterior chest pain in which coronary artery calcification (CAC) was clearly displayed using PMCT scan. The entire coronary artery system was almost reconstructed via multiplanar reformation (MPR) and volume-rendering reconstruction (VR), and the total calcium score of the coronary arteries was obtained with CaScoring automatic analysis software. The results showed that CAC was conspicuous; the total calcium score was 640.3, considerably higher than 400. The pulmonary ground-glass opacity (GGO) and small amount of fluid both in the subglottic trachea and main bronchi were also found. The imaging results confirmed those of autopsy. In addition, the results concluded that PMCT might serve as an invaluable adjunct to the classic autopsy procedure.

OBJECTIVE@#To study the difference of Han female adolescent bone development in Henan and Zhejiang province.@*METHODS@#All radiography including sternal end of clavicle and six main bone joints were taken from 599 female adolescents with age between 12 to 19 in Henan and Zhejiang province. Twenty four skeletal development indexes were analyzed based on "The Grading Standards" of skeletal growth of teenagers and then the bone age were calculated using mathematical model functions. The ratios of the bone age and the chronological age were analyzed by statistical software.@*RESULTS@#The development of Henan female adolescents' skeleton was about 0.39 years earlier than that in Zhejiang at the age of 14-15 years old. The development of Henan female adolescents' skeleton was about 0.37 years later than that in Zhejiang at the age of 15-16 years old. The development of Henan female adolescents' skeleton was about 0.38 years later than that in Zhejiang at the age of 18-19 years old. There was no statistics significance in other age group.@*CONCLUSION@#The female adolescent bone development in Henan province is faster at earlier stage and then slower than that in Zhejiang province. The results provide potential value for the forensic medicine, anthropology and clinical medicine.
