ABSTRACT

Objective:To explore the feasibility and predictive value of Transit-Time Flow Measurement(TTFM) processed by Fast Fourier Transform(FFT) in evaluating the patency of grafts after coronary artery bypass grafting(CABG).Methods:The TTFM waveforms recorded during the operation of 114 CABG patients in our hospital from January 2015 to February 2017 were processed by FFT, the patients were followed up with CTCA after operation to evaluate the predictive value for graft failure.Results:320 grafts were grafted with the patency rate of 80.3%(257/320). The patency rate of LIMA group was 89.4%(101/113), and SVG group was 75.4%(156/207). H0, H1, H0/H1, and P1 of all grafts, H1and P1 in LIMA group, and H0, H1, P1 in SVG group were significantly different( P<0.05). In logistic regression, decreasing of H0( OR=0.92, 95% CI: 0.90-0.95) and increasing of P1( OR=2.26, 95% CI: 1.64-3.10) in all graft groups increased the risk of graft failure. In the LIMA group, increasing of H1( OR=3.57, 95% CI: 1.79-7.12) and P1( OR=1.53, 95% CI: 1.01-2.33) increased the risk of graft failure. In the SVG group, decreasing of H0( OR=0.83, 95% CI: 0.77-0.89) and H1( OR=0.05, 95% CI: 0.02-0.14), increasing of P1( OR=9.53, 95% CI: 3.04-29.86) increased the risk of graft failure. The ROC curve showed that H0 and P1 had a moderate degree of predictive accuracy in all graft groups. H1 and H0/H1 had a moderate degree of predictive accuracy in LIMA group, and H0 and H1 had a high degree of prediction, P1 had a moderate degree of predictive accuracy in SVG group. Conclusion:TTFM waveform processed by FFT has predictive value for the patency rate of CABG.

ABSTRACT

Objective:To analyze the diagnostic efficacy of targeted biopsy (TB) versus targeted biopsy combined with systematic biopsy (TB+ SB) for patients with multi-parametric magnetic resonance imaging (mpMRI) prostate imaging-reporting and data system (PI-RADS) score of 4-5.Methods:The clinical data of 378 patients with mpMRI PI-RADS score of 4-5 in Nanjing Drum Tower Hospital from January 2018 to February 2020 who received prostate TB+ SB were retrospectively analyzed. Median age was 69 (64, 75) years old, median prostate specific antigen was 9.5 (6.7, 16.3) ng/ ml, and median prostate volume was 34.1 (23.5, 48.4) ml. There were 240 cases with PI-RADS score of 4 and 138 cases with PI-RADS score of 5. Evaluating Gleason score of positive biopsy pathology and using χ 2 test or Fisher exact test to analyze the detection of prostate cancer (PCa) and clinically significant prostate cancer(CsPCa) by TB versus TB+ SB. Results:Of the all 378 cases, 88 cases (23.3%) were negative and 290 cases (76.7%) were positive. The average number of needle for TB was 2.4 per person, while SB was 12 per person. TB and SB had no statistically significant difference in the detection rate of PCa (73.3% vs. 68.3%, P=0.129) and CsPCa (55.8% vs. 49.7%, P=0.094) and in the accuracy (79.1% vs. 77.8%, P=0.658), but had a statistically significant difference in the positive rate (64.2% vs. 23.1%, P < 0.001). The pathological coincidence rate of TB and TB+ SB was 92.3%. There was no statistical difference in the detection rate of PCa (73.3% vs. 76.7%, P=0.275) and CsPCa (55.8% vs. 62.2%, P=0.076) between TB and TB+ SB. The missed diagnosis rate of TB for PCa was 4.5%, for CsPCa was 10.2%. For patients with PI-RADS score of 4, TB had no significant difference in the detection rate of PCa (65.4% vs. 69.2%, P=0.381) and CsPCa (46.7% vs. 52.9%, P=0.171) from TB+ SB. The accuracy of TB was 82.1%. The missed diagnosis rate of TB for PCa was 5.4%, for CsPCa was 11.8%. For patients with PI-RADS score of 5, TB had no significant difference in the detection rate of PCa (87.0% vs. 89.9%, P=0.452) and CsPCa (71.7% vs. 78.3%, P=0.211) from TB+ SB. The accuracy of TB was 73.9%. The missed diagnosis rate of TB for PCa was 3.2%, for CsPCa was 8.3%. Conclusions:For high-risk prostate cancer patients with PI-RADS score of 4-5, TB can obtain a detection effect similar to that of TB+ SB with fewer needles, but there is still the possibility of inaccurate diagnosis and missed diagnosis.

ABSTRACT

Objective:To evaluate diagnostic value of contrast-enhanced harmonic endoscopic ultrasonography (CEH-EUS) for pancreatic cystic lesions.Methods:Endoscopic and clinical follow-up data of patients with pancreatic cystic lesions diagnosed by EUS in Department of Gastroenterology of the First Affiliated Hospital of Naval Medical University with CEH-EUS video from March 2013 to April 2020 was retrospectively analyzed.Results:A total of 36 patients were included. There were 16 cases of serous cystadenomas (SCA), 10 cases of mucinous cystic neoplasm (MCN), 5 cases of intraductal papillary mucinous neoplasms (IPMN, 3 with complex type, 2 with main pancreatic duct type) and 5 cases of pancreatic pseudocyst (PPC). 87.5%(14/16) of SCA and 86.7%(13/15) of MCN+ IPMN had hyperenhanced cystic wall with obvious peak and similar washout as surrounding tissue, whereas only 20%(1/5) PPC had hyperenhanced cystic wall. The hyperenhancing effect of PPC was significantly lower than that of SCA and MCN+ IPMN ( P=0.0035 and P=0.0048, respectively ). Mural nodules were detected in 17 cases of pancreatic cystic lesions by EUS, of which 3 cases had hyperenhanced mural modules and 14 cases had hypoenhanced mural nodules by CEH-EUS. Patients showing hyperenhanced mural modules were all finally diagnosed as pancreatic malignancy (1 IPMN, 2 MCN), and the accuracy was 100%. Conclusions:CEH-EUS can have a obvious advantage of differentiating pseudocyst and other pancreatic cystic lesions, while not very useful for differentiating SCA and MCN. Pancreatic cystic lesions showing hyperenhanced mural nodules under CEH-EUS may imply malignancy potential.

ABSTRACT

46,XY disorders of sex development (DSD) is characterized by incomplete masculinization genitalia, with gonadal dysplasia and with/without the presence of Müllerian structures. At least 30 genes related to 46,XY DSD have been found. However, the clinical phenotypes of patients with different gene mutations overlap, and accurate diagnosis relies on gene sequencing technology. Therefore, this study aims to determine the prevalence of pathogenic mutations in a Chinese cohort with 46,XY DSD by the targeted next-generation sequencing (NGS) technology. Eighty-seven 46,XY DSD patients were enrolled from the Peking Union Medical College Hospital (Beijing, China). A total of fifty-four rare variants were identified in 60 patients with 46,XY DSD. The incidence of these rare variants was approximately 69.0% (60/87). Twenty-five novel variants and 29 reported variants were identified. Based on the American College of Medical Genetics and Genomics (ACMG) guidelines, thirty-three variants were classified as pathogenic or likely pathogenic variants and 21 variants were assessed as variants of uncertain significance. The overall diagnostic rate was about 42.5% based on the pathogenic and likely pathogenic variants. Androgen receptor (AR), steroid 5-alpha-reductase 2 (SRD5A2) and nuclear receptor subfamily 5 Group A member 1 (NR5A1) gene variants were identified in 21, 13 and 13 patients, respectively. The incidence of these three gene variants was about 78.3% (47/60) in patients with rare variants. It is concluded that targeted NGS is an effective method to detect pathogenic mutations in 46,XY DSD patients and AR, SRD5A2, and NR5A1 genes were the most common pathogenic genes in our cohort.

ABSTRACT

BACKGROUND@#The lack of pathological quality control standard in detecting epidermal growth factor receptor (EGFR) gene mutation in malignant pleural effusion leads to confusion in the interpretation of detection results and the clinical use of EGFR-tyrosine kinase inhibitor (TKI). Therefore, it is very important to propose quality control standards and guide the detection of EGFR mutation in pleural effusion. The aim of this study is to retrospectively analyze the results of EGFR gene mutation in pleural effusion sediment section according to strict pathological quality control standards, and the therapeutic effect of EGFR-TKIs guided by this detection results.@*METHODS@#From January 2012 to June 2018, the clinical data of patients with pleural effusion collected from Department of Pathology of Peking Union Medical College Hospital were analyzed retrospectively. Among them, 132 patients with relatively complete clinical data and with EGFR gene mutation detection of paraffin-embedded pleural effusion sediment section according to the established quality control standard were included. According to the results of EGFR gene mutation, it was divided into positive group and negative group, and the efficacy of EGFR-TKIs in different groups was compared.@*RESULTS@#After the centrifugation of pleural effusion, the sediment was embedded in paraffin, sectioned, and observed under the microscope after HE staining. If the number of tumor cells ≥100, it met the pathological quality control standard, and it could be used for subsequent EGFR gene mutation detection. EGFR gene mutations were detected in 72 (54.5%) of 132 patients. EGFR-TKIs were used in 69 of 72 mutation positive patients. Of 60 EGFR mutation negative patients, only 15 used EGFR-TKIs. In EGFR mutation positive group, the disease control rate (DCR) was 95.8%, and the median progression-free survival (PFS) was 11 months. In EGFR mutation negative group, the DCR was 0%, and the median PFS was 1 month. The DCR and PFS were significantly different between the two groups (P<0.05).@*CONCLUSIONS@#According to the pathological quality control standards, the embedded section of pleural fluid sediment can be used to detect EGFR gene mutation, and the results can be used to guide the clinical use of EGFR-TKIs.

ABSTRACT

Although the tumor suppressor P53 is known to regulate a broad network of signaling pathways, it is still unclear how certain drugs influence these P53 signaling networks. Here, we used a comprehensive single-cell multiomics view of the effects of ginsenosides on cancer cells. Transcriptome and proteome profiling revealed that the antitumor activity of ginsenosides is closely associated with P53 protein. A miRNA-proteome interaction network revealed that P53 controlled the transcription of at least 38 proteins, and proteome-metabolome profiling analysis revealed that P53 regulated proteins involved in nucleotide metabolism, amino acid metabolism and "Warburg effect". The results of integrative multiomics analysis revealed P53 protein as a potential key target that influences the anti-tumor activity of ginsenosides. Furthermore, by applying affinity mass spectrometry (MS) screening and surface plasmon resonance fragment library screening, we confirmed that 20()-protopanaxatriol directly targeted adjacent regions of the P53 DNA-binding pocket and promoted the stability of P53-DNA interactions, which further induced a series of omics changes.

ABSTRACT

Breast cancer is a malignant tumor with the highest morbidity and mortality in female in recent years, and it is a complex disease that affects human health. Studies have shown that dynamic network biomarkers (DNB) can effectively identify critical states at which complex diseases such as breast cancer change from a normal state to a disease state. However, the traditional DNB method requires data from multiple samples in the same disease state, which is usually unachievable in clinical diagnosis. This paper quantitatively analyzes the time series data of MCF-7 breast cancer cells and finds the DNB module of a single sample in the time series based on landscape DNB (L-DNB) method. Then, a comprehensive index is constructed to detect its early warning signals to determine the critical state of breast cancer cell differentiation. The results of this study may be of great significance for the prevention and early diagnosis of breast cancer. It is expected that this paper can provide references for the related research of breast cancer.

ABSTRACT

According to the classification of traditional Chinese medicine syndromes of coronavirus disease 2019 by the national competent authority, this study determined that human coronavirus 229 E(HCoV-229 E) was infected in a mouse model of cold and dampness syndrome, so as to build the human coronavirus pneumonia with pestilence attacking lung syndrome model. The model can simulate the traditional Chinese medicine treatment of common disease syndromes in Coronavirus Disease 2019 Diagnosis and Treatment Program(the sixth edition for trial). Specific steps were as follows. ABALB/c mouse model of cold and dampness syndrome was established, based on which, HCoV-229 E virus was infected; then the experiment was divided into normal control group, infection control group, cold-dampness control group, cold-dampness infection group(the model group), high-dose Chaiyin Particles group(8.8 g·kg~(-1)·d~(-1)), and low-dose Chaiyin Particles group(4.4 g·kg~(-1)·d~(-1)). On the day of infection, Chaiyin Particles was given for three consecutive days. Lung tissues were collected the day after the last dose, and the lung index and inhibition rate were calculated. The nucleic acid of lung tissue was extracted, and the HCoV-229 E virus load was detected by Real-time fluorescent quantitative RT-PCR. Blood leukocytes were separated, and the percentage of T and B lymphocytes was detected by flow cytometry. Lung tissue protein was extracted, and IL-6, IL-10, TNF-α and IFN-γ contents were detected by ELISA. High and low-dose Chaiyin Particles significantly reduced the lung index(P<0.01) of mice of human coronavirus pneumonia with pestilence attacking the lung syndrome, and the inhibition rates were 61.02% and 55.45%, respectively. Compared with the model control group, high and low-dose Chaiyin Particles significantly increased cross blood CD4~+ T lymphocytes, CD8~+T lymphocytes and total B lymphocyte percentage(P<0.05, P<0.01), and reduced IL-10, TNF-α and IFN-γ levels in lungs(P<0.01). In vitro results showed that TC_(50), TC_0, IC_(50) and TI of Chaiyin Particles were 4.46 mg·mL~(-1), 3.13 mg·mL~(-1), 1.12 mg·mL~(-1) and 4. The control group of in vitro culture cells had no HCoV-229 E virus nucleic acid expression. The expression of HCoV-229 E virus nucleic acid in the virus control group was 1.48×10~7 copies/mL, and Chaiyin Particles significantly reduced HCoV-229 E expression at doses of 3.13 and 1.56 mg·mL~(-1), and the expression of HCoV-229 E nucleic acid was 9.47×10~5 and 9.47×10~6 copies/mL, respectively. Chaiyin Particles has a better effect on the mouse model with human coronavirus pneumonia with pestilence attacking the lung syndrome, and could play a role by enhancing immunity, and reducing inflammatory factor expression.

ABSTRACT

italic>Shiraia bambusiccola is an important medicinal fungus in China. Hypocrellins with perylenequinone skeleton are main bioactive components of Shiraia bambusiccola, which are widely used in food, medicine, pesticide and other fields as natural photosensitizers. For example, "hypocrellin ointment" has already been used clinically. As a rare and vulnerable species, wild Shiraia bambusiccola resources are very limited. Due to the complex structure and chanllenge in chemical total synthesis of hypocrellins, it is urgent to find an effective strategy to rationally utilize its medicinal value while protecting the wild resources. In this study, a candidate gene cluster hpc was identified in Shiraia sp. cfcc 84681 based on careful bioinformatic analysis. A heterologous expression system for hpc gene cluster was successfully constructed and a mutant strain with high yield of hypocrellins was obtained, which mainly produced hypocrellin A and isohypocrellin A. The main ingredients in the mutant strain are consistent with that in the wild Shiraia bambusiccola. These results provide a new strategy to solve the shortage of wild Shiraia bambusiccola resources.

ABSTRACT

"TCM syndrome of plague attack lung" is a classification of traditional Chinese medicine syndromes of the novel coronavirus pneumonia by the Beijing Municipal Administration of Traditional Chinese Medicine. In this study, a mouse model combining disease with syndrome of human coronavirus pneumonia with cold-dampness pestilence attacking the lung was established for the first time, and the therapeutic effect of matrine sodium chloride injection was evaluated based on immune regulation and inflammatory damage. Lung index, lung index inhibition rate and HE stain were used to evaluate the therapeutic effect of matrine sodium chloride injection on the model mice; the viral load in lung tissue was measured by RT-PCR to evaluate its antiviral effect; the percentage of CD4+ T cells, CD8+ T cells and B cells were detected by flow cytometry to evaluate its immunomodulatory effect; the production of interleukin 6 (IL-6), IL-10, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured by ELISA to evaluate its anti-inflammatory effect. All interventions and operations in the experiment were approved by the Animal Ethics Committee of the Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences, and conformed to the Guide for the Care and Use of Laboratory Animals published by the US National Institutes of Health (NIH) and Beijing Experimental Animal Ethics Committee. The results showed that intraperitoneal injection of the high-dose (36.67 mL·kg-1·d-1) and low-dose (18.33 mL·kg-1·d-1) of matrine sodium chloride injection significantly improved the pathological damage of lung tissue and reduced lung index. The lung index inhibition rates were 86.86% and 76.53%, respectively. The production of IL-6, IL-10, TNF-α, IFN-γ, as well as the viral load in lung tissue were reduced significantly compared to the model; the percentage of CD4+ T cells, CD8+ T cells and B cells in peripheral blood were increased compared to the model. These results indicated that the matrine sodium chloride injection has an evident therapeutic effect on the model, and its mechanism was related to the inhibition virus replication, regulation of immunity function and inhibition of inflammatory factor release. This study provided laboratory data support for matrine sodium chloride injection which was used to treat the novel coronavirus pneumonia in clinical in Hubei province. These results indicated that the matrine sodium chloride injection has a good prospect for prevention and treatment of the novel coronavirus pneumonia.

ABSTRACT

Objective@#Despite the remarkable progress in efforts to control disease spread, the nationwide elimination of hepatitis B in China is still hindered by the persistently high rate of hepatitis B virus (HBV) infection in Western China. This study aimed to evaluate the strategy of hepatitis B prevention and control in Western China and identify potential areas and strategies for improvement.@*Methods@#Susceptible population vaccination, health education, professional training of doctors, and other prevention and control measures have been implemented in Wuwei city since 2010. Data were obtained from three representative cross-sectional serosurveys conducted in 2010, 2013, and 2015. The serum samples were subjected to enzyme-linked immunosorbent assays to detect the following seromarkers: HBV surface antigen (HBsAg), antibody against hepatitis B surface antigen (anti-HBs), and antibody against hepatitis B core antigen (anti-HBc). Estimates of variance were determined using Taylor series linearization methods.@*Results@#The three serosurveys revealed decreases in the prevalence of HBsAg (7.19% in 2010 @*Conclusion@#Although vaccine-based prevention and control measures reduced the rate of HBV infection in Wuwei City over time, the hepatitis B infection rate in children younger than 10 years was still higher than the national average level. Therefore, the prevention and control of mother-to-child transmission and the management of the infected should be the focus of future prevention and control work.

ABSTRACT

By integration of traditional and Western medicine under particular historical conditions in China, some doctors of Western medicine are learning traditional Chinese medicine (TCM)and try to interconnect the two theories.To promote medical progress, they provide TCM services in clinic, such as acupuncture, herbal medicine, etc.But as we know that the laws are lacking for the doctors of Western medicine who want to carry out traditional Chinese medicine service.For the reason, the paper holds that at present there are three fundamental problems that should be solved.First of all, it must be clear that doctors should have qualifications and conditions to provide TCM service.Secondly, it must be clear that the doctors should have practicing scope to guarantee medical security and medical quality.Thirdly, it is imperative to strengthen TCM education and training for doctors.Now it is necessary to further strengthen the standardization of health supervision and law enforcement.
