It is feasible to use MPM to diagnose gastric cancer by "optical biopsy." With miniaturization and integration of endoscopy, MPM has the potential to provide real-time histological diagnosis without invasive biopsy for gastric cancer in the future.
Our data showed a significantly upward-shifting trend in the proportions of small PGC, primarily in elderly male patients, in contrast to a downward shifting trend in NPGC over the most recent 8-year period in Chinese patients.
In this retrospective study, clinical data including clinical manifestations, routine blood tests, chest radiographic imaging from 77 severe cases of SARS treated with integrated Chinese and Western medicine were collected and statistically analyzed. Twenty-nine (37.6%) patients were admitted to the intensive care unit, non-invasive ventilation was used in 40 (51.9%) cases, and invasive ventilatory procedure was performed in eight (10.3%) cases. Seventy (90.9%) patients were clinically cured and seven (9.0%) died. The duration of defervescence was 8.3 +/- 5.0 days after admission. In the early stage, normal leucocyte count was seen in 46 (75.4%) of the 61 patients tested, decreased leucocyte count in 13 (21.3%) and elevated leucocyte count in only two (3.2%) cases. A decreased lymphocyte count was also seen in 23 (37.7%) cases of the 61 patients tested on admission, and by day 14, the number of patients with decreased lymphocyte count (1.11 +/- 0.66 x 10(9)) increased to 32 (47.7%) in 67 cases examined. Neutral granulocyte count was normal or decreased in 58 (95.0%) patients on admission, but elevated from the 7th day onward and peaked on day 21 in 32 (65.3%) of the 49 cases tested. All of the blood abnormalities returned to normal in the convalescent stage. Twenty-nine (37.6%) of the 77 severe cases of SARS patients demonstrated an extensive lung involvement. In comparison with the non-severe SARS cases, this group of patients showed significantly more pneumonic air-space opacities and ground glass-like changes on the chest radiographs (p < 0.05, chi2 test). The role Chinese medicine played in the treatment of SARS was discussed.
Background: Congenital pseudarthrosis of the tibia (CPT) is a rare and difficult to treat congenital disease in neonates. Our team's previous study found that exosomes derived from serum of children with CPT can reduce the effect of bone formation. In this study, we used ultrasound bone densitometry to detect the bone quality between children with CPT and those non-metabolic disease children, to determine the bone strength of children with CPT. Methods: A total of 37 CPT children and 40 children without the bone metabolic disease (control group) were recruited in our hospital. The ultrasonic bone densitometer was used to examine the bilateral calcaneus of the subjects. According to the measurement results, we collected the broadband ultrasonic attenuation (BUA), sound transmission velocity (SOS), quantitative ultrasound index (QUI), bone strength index(STI) and bone mineral density estimation(BMDe) values. For the intergroup analysis, t test was used to determine the differences of various quantitative measurements. Multivariable regression was used to examine the associations between quantitive ultrasound measurements differences and age, body mass index (BMI), neurofibromatosis type 1 (NF1) and CPT Crawford type. Intra-class correlation coefficient (ICC) was calculated to estimate intra- and inter-rater agreements. Results: Seventy-four calcaneus scans from CPT patients (23 boys and 14 girls) and 80 calcaneus scans (24 boys and 16 girls) from the control. The CPT patients exhibited significantly lower SOS (1368.75±136.78 m/s), STI (7.2319±38.6525), QUI (8.2532±56.1720) and BMDe (-0.0241±0.3552 g/cm3) than the control (SOS: 1416.02±66.15 m/s, STI: 7.96±16.884, QUI: 28.8299±25.461, BMDe: 0.0180±0.1610 g/cm3). Multiple linear regression revealed that SOS, STI, QUI was statistically significant and negatively correlated with CPT Crawford classification.Conclusions: We found the incidence of decreased bone quality in CPT group was higher than that in the non-bone metabolic disease group. This phenomenon was not related to NF1 while related to CPT Crawford classification, which suggested that the higher grade of the CPT Crawford classification, the lower the bone strength and the higher the risk of fracture.
Background Understanding the vascular anatomy is critical for performing central vascular ligation (CVL) in right hemicolectomy with complete mesocolic excision (CME). This study aimed to investigate the predictive value of multi-slice spiral computed tomography (MSCT) with coronal reconstruction in right hemicolectomy with CME. Methods This is a retrospective descriptive study. Eighty patients with right colon cancer who underwent right hemicolectomy from December 2015 to January 2020 were included. The intraoperative reports (including imaging data) and MSCT images with coronal reconstruction were analysed and compared. The detection rates of the ileocolic vein (ICV) and ileocolic artery (ICA) roots and the accuracy in predicting their anatomical relationship were analysed. The detection rate and accuracy in predicting the location of the gastrocolic trunk of Henle (GTH), middle colic artery (MCA) and middle colic vein (MCV) were analysed. The distance from the ICV root to the GTH root (ICV-GTH distance) was measured and analysed. The maximum distance from the left side of the superior mesenteric artery (SMA) to the right side of the superior mesenteric vein (SMV), named the ‘lsSMA-rsSMV distance’, was also measured and analysed. Results In seventy-four (92.5%) patients, both the ICV and ICA roots were located; their anatomical relationship was determined by MSCT, and the accuracy of the prediction was 97.2% (72/74). The GTH was located by MSCT in 75 (93.7%) patients, and the accuracy of the prediction was 97.33% (73/75). The MCA was located by MSCT in 47 (58.75%) patients, and the accuracy was 78.72% (37/47). The MCV was located by MSCT in 51 (63.75%) patients, and the accuracy of the prediction was 84.31% (43/51). The ICV-GTH distance was measured in 73 (91.2%) patients, and the mean distance was 4.28 ± 2.5 cm. The lsSMA-rsSMV distance was measured in 76 (95%) patients, and the mean distance was 2.21 ± 0.6 cm. Conclusions With its satisfactory accuracy in predicting and visualising the information of key anatomical sites, MSCT with coronary reconstruction has some predictive value in CME with CVL in right hemicolectomy.
Background:Understanding vascular anatomy is critical for performing central vascular ligation (CVL) in the right hemicolectomy with complete mesocolic excision (CME). This study was aimed to investigate the predictive value of multi-slice spiral computed tomography (MSCT) with coronal reconstruction in the right hemicolectomy. Methods:Eighty patients who underwent right hemicolectomy in our hospital were included. The intraoperative imaging data and the images of MSCT with coronal reconstruction were analyzed retrospectively. The detection rate of the ileocolic vein (ICV) and ileocolic artery (ICA) location and the accuracy of the preoperative prediction of their anatomical relationship were analyzed. The detection rate and preoperative prediction accuracy of the gastrocolic trunk of Henle (GTH), middle colic artery (MCA), and middle colin vein (MCV) were analyzed. The distance from the ICV root to the GTH root (ICV-GTH distance) was measured and analyzed. The maximum distance from the left edge of the superior mesenteric artery (SMA) to the right edge of the superior mesenteric vein (SMV), named “leSMA-reSMV distance,” was measured and analyzed too.Results:74 (92.5%) patients had been located both the ICV and ICA roots and determined the anatomical relationship between them by MSCT, of which 72 were confirmed by intraoperative findings,and the accuracy was 90% (72/80). GTH was located by MSCT in 75 (93.7%) patients, and the accuracy was 91.25% (73/80). MCA was located by MSCT in 47(58.75%) patients, and the accuracy was 46.25% (37/80). MCV was located by MSCT in 51 (63.75%)patients, and the accuracy was 53.75% (43/80). The ICV-GTH distance was measured in 73 (91.2%) patients, and the mean distance was 4.28±2.5cm. The leSMA-reSMV distance was measured in 76 (95%) patients, and the mean distance was 2.21±0.6cm. Conclusions:MSCT with coronary reconstruction can locate the roots of ICV, ICA, and GTH, predict the boundary of SMA and SMV, analyze the anatomical relationship between them, and estimate the location and range of central ligation region, which are of some predictive value in central vascular ligation in the right hemicolectomy with CME.
