ABSTRACT

Objective:To investigate high resolution CT (HRCT) manifestations and clinical features of patients infected with the novel coronavirus B.1.617.2 variant.Methods:A total of 125 patients with the novel coronavirus B.1.617.2 variant in Guangzhou Eighth People′s Hospital from May 21 to June 9, 2021 was enrolled. There were 52 males and 73 females, aged from 1 to 92 years old with a median age of 47 year. The clinical features and HRCT characteristics were analyzed retrospectively.Results:Of the 125 patients, the main clinical manifestations were fever in 54 patients, cough in 50 patients, pharyngeal discomfort in 39 patients, and diarrhea in 5 patients. HRCT showed pneumonia in 96 cases, which predominantly had ground-glass opacities in 92 cases, ground-glass opacities combined with local consolidation in 22 cases, consolidation in 11 cases, intralobular interstitial thickening in 51 cases, centrilobular structural thickening in 23 cases, and cord-like lesions in 33 cases. One patient had pleural effusion, and no enlarged lymph nodes were observed in all patients. The lesions were distributed in the subpleural and/or peripheral lung in 96 cases and along the bronchovascular bundle (middle and inner zone) in 24 cases. The time interval from onset to positive HRCT was 3 (1, 4) days in 96 patients with pneumonia on HRCT. HRCT showed absorption after the imaging findings reaching the peak in 20 patients, and the time interval between the first positive HRCT findings and the peak imaging was 6 (3, 7) days in these 20 patients.Conclusions:The novel coronavirus B.1.617.2 variant has a strong infectivity, short viral latency. Lung injury is decreaseel. People of all ages are susceptible and the diseasemay have rapid pnegression. HRCT mainly shows ground glass opacities, which are more common in subpleural and/or in the lung periphery, with interlobular thickening.

ABSTRACT

BACKGROUND@#Acquired immune deficiency syndrome (AIDS)-related non-Hodgkin lymphoma (AR-NHL) is a high-risk factor for morbidity and mortality in patients with AIDS. This study aimed to determine the prognostic factors associated with overall survival (OS) and to develop a prognostic nomogram incorporating computed tomography imaging features in patients with acquired immune deficiency syndrome-related non-Hodgkin lymphoma (AR-NHL).@*METHODS@#A total of 121 AR-NHL patients between July 2012 and November 2019 were retrospectively reviewed. Clinical and radiological independent predictors of OS were confirmed using multivariable Cox analysis. A prognostic nomogram was constructed based on the above clinical and radiological factors and then provided optimum accuracy in predicting OS. The predictive accuracy of the nomogram was determined by Harrell C-statistic. Kaplan-Meier survival analysis was used to determine median OS. The prognostic value of adjuvant therapy was evaluated in different subgroups.@*RESULTS@#In the multivariate Cox regression analysis, involvement of mediastinal or hilar lymph nodes, liver, necrosis in the lesions, the treatment with chemotherapy, and the CD4 ≤100 cells/μL were independent risk factors for poor OS (all P < 0.050). The predictive nomogram based on Cox regression has good discrimination (Harrell C-index = 0.716) and good calibration (Hosmer-Lemeshow test, P = 0.620) in high- and low-risk groups. Only patients in the high-risk group who received adjuvant chemotherapy had a significantly better survival outcome.@*CONCLUSION@#A survival-predicting nomogram was developed in this study, which was effective in assessing the survival outcomes of patients with AR-NHL. Notably, decision-making of chemotherapy regimens and more frequent follow-up should be considered in the high-risk group determined by this model.

ABSTRACT

Objective:To investigate the initial high resolution CT (HRCT) manifestations and clinical features of imported COVID-19 in Guangzhou.Methods:A retrospective analysis of 91 COVID-19 patients admitted to the Guangzhou Eighth People's Hospital from January 22 to 30, 2020 was performed including 39 males and 52 females, with a median age of 50 (33-62) years,then their clinical features and HRCT characteristics were analyzed.Results:The main clinical presentations included fever in 70 cases and cough in 57 cases(mainly dry cough in 39 cases). The first time HRCT showed that 24 cases with COVID-19 were normal, however other 67 cases were abnormal. The ground glass opacity in the lung on HRCT was found in 65 cases, including 64 cases with dilated blood vessel crossing the lesion, 50 cases with thickened adjacent pleura, and 47 cases with thickening of interstitial septum. The patchy opacity was seen in 42 cases, and no enlarged lymph nodes were observed in all patients. As for the lesion distribution, there were two cases with bilateral diffuse changes, 57 cases with multiple lesions, 8 cases with the lesion in only one lobe. The lesions were mainly located under the pleura area in 46 cases, including 39 cases in the lower lobe and other 7 cases in the upper lobe. And there were 13 cases without characteristic distribution in the lung.Conclusion:The initial images of COVID-19 in Guangzhou mainly showed multiple ground glass opacity, which were mostly seen in the subpleural and lower lung fields, most of them with thickened pulmonary interstitium. Guangzhou has a higher proportion of COVID-19 patients with mild and general patients, and some confirmed patients show negative HRCT for the first time. Patients without HRCT changes should be reviewed in a timely manner.

ABSTRACT

The DNA extraction method of animal medicine material is difficult and un-unified,which limits the application of molecular identification to identify animal medicines.In this study,based on the DNA extraction theory of SDS,we assessed the effects of three elements including different EDTA concentrations (0.025 mol·L-1,0.25 mol· L-1,and 0.5 mol· L-1) and whether containing NaCl and Triton X-100 in the lysis buffer on the quality of DNA extracted from different kinds of animal medicine.The optimized lysis buffer was used to extract DNA from 121 commercial animal medicines for original and species identification.The results showed that the lysis buffer of 1% SDS,0.03 mol· L-1 Tris-HCl,0.25 mol· L-1 EDTA and 0.2 mol· L-1 NaCl had the optimum effect on DNA extraction.This lysis buffer can obtain DNA from animal medicine which is difficult to extract,such as Cicadae periostracum.The DNA extractions of 121 commercial animal medicines by optimized lysis buffer can satisfy the experimental requirements for molecular identification.All samples of commercial animal medicines can be accurately identified to the level of species.It was concluded that optimized lysis buffer can be used in the DNA extraction of different kinds of animal medicines except shells,secretions and processed products.This method provides technique support for the molecular identification of animal medicines.

ABSTRACT

Objective:To analyze the consistency of HER-2 expression among endoscopic biopsy and radical operation specimens of gastric adenocarcinoma and to investigate the clinical application value of HER-2 detection in trastuzumab treated patients. Methods:From March 2013 to February 2014, 167 patients from Shanghai Changhai Hospital were diagnosed with gastric adenocarcinoma using endoscopic biopsy specimens. The corresponding surgical specimens were collected for pathological analysis. The relevant clinical and pathological data were collected. HER-2 protein expression of endoscopic biopsy specimens was detected by immunohistochemistry (IHC). HER-2 protein expression and gene amplification status of the corresponding tumor resection specimens were detected by IHC and fluorescence in situ hybridization (FISH). Results were analyzed for clinicopathological characteristics. Results:Among the 167 cas-es, 18 cases (10.8%) were HER-2 positive, including 10 cases showing IHC3+and 8 cases showing IHC2+with FISH positive. The consis-tency rate result among endoscopic biopsy and surgical operation specimens was 82%. Excluding the cases showing IHC2+, the true positive rate and the true negative rate were 73.3%and 97.0%, respectively. Conclusion:HER-2 detection of endoscopic biopsy speci-men by IHC shows great predictive value. The main reason for the difference of surgery and biopsy specimens is the heterogeneity of tumor expression. Increasing the number of specimens and combined testing with FISH are important methods to reduce misjudge-ment.

ABSTRACT

The renin-angiotensin system exists locally in bone tissue.The RAS components and the active peptide angiotensinⅡ (Ang Ⅱ)within RAS are directly involved in the pathophysi-ological process of regulating bone metabolism.Ang Ⅱ exerts the effects via its receptors expressed in osteoblasts and osteoclasts. This paper reviewed the pathways of classical RAS,explained the tissue RAS-induced tissue injuries,and especially elaborated the regulation of RAS active peptide Ang Ⅱ on target genes and in-tracellular signaling pathways in osteoblasts,the action of Ang Ⅱon osteoclastic function via acting on osteoblasts,and the inter-action of Ang Ⅱ receptors involved in the modulation on bone metabolism.

ABSTRACT

matK is one of the core DNA barcode markers for plant DNA barcode identification and its universality using single makers has been in controversy. However, the universalities of different matK primer pairs in same seed plant group (order) and same matK primer pairs in different seed plant groups (order) are lack of systematic research. In this study, we collected 14563 full-length matK sequences of 11429 species of 3292 genera in 239 families belonging to 36 orders in seed plants. The universalities of 13 matK primer pairs and its 78 primer com-binations have been assessed using bioinformatics methods. The results indicated that xf/5r, 1F/8R, 390F/1326R and 3F_KIM/1R_KIM were the four most universality primer pairs. The four markers' universalities were 91.18%, 84.65%, 79.81% and 80.94% respectively in all 11429 seed plants. The most universality primer pairs in different orders were different. For each order, the primer pair with maximum universality was different. the xf/5r was the basal primer pair for primer combination and 1F/8R, 1F/1R, M3/M4 and 3F_KIM/1R_KIM could be the complementary primer pairs. This study could be a valuable resource for the primer selection of the research DNA barcoding identification in seed plants.
