ABSTRACT

Objective:To explore the value of contrast-enhanced ultrasound (CEUS) combined with Ovarian-Adnexal Reporting and Data System (O-RADS US) risk stratification and management system in differential diagnosis of ovarian-adnexal mass.Methods:Fifty-six patients with ovarian-adnexal mass who received transabdominal transvaginal ultrasound and CEUS in the Third People′s Hospital of Longgang District from September 2018 to January 2021 were enrolled. The images were classified by O-RADS US and diagnosed by CEUS by experienced and senior radiologist. On the basis of O-RADS US classification, the enhancement time, enhancement level and enhancement mode of CEUS were combined to upgrade or degrade the classification results of O-RADS US. The diagnostic accuracy was assessed using ROC curve analysis, the area under the ROC curve (AUC) was calculated. The reproducibility of O-RADS US was assessed by another senior radiologist.Results:The AUC of O-RADS US for diagnosing benign and malignant ovarian-adnexal masses was 0.844(0.722, 0.927), the AUC of CEUS was 0.833(0.710, 0.920), the AUC of O-RADS US combined with CEUS was 0.940(0.842, 0.986) (compared with O-RADS US, P=0.020; compared with CEUS, P=0.031). The intra-class correlation coefficient (ICC) was 0.897(0.824, 0.940) for O-RADS US. Conclusions:CEUS combined with O-RADS US classification can effectively improve the diagnostic efficiency for benign and malignant ovarian-adnexal masses.

ABSTRACT

Objective:Taking ultrafine granular powder of Salviae Miltiorrhizae Radix et Rhizoma (UGPSMR) as the research object, to establish a method for evaluating its physical properties. Method:A method was established for measuring the particle size distribution and specific surface area of UGPSMR, and the methodological investigation was carried out. A total of 15 physical indicators [D90 (particle size value when the cumulative particle distribution reaches 90%), particle size distribution range, particle size distribution width, bulk density, tap density, intergranular porosity, Carr index, specific surface area, pore volume, angle of repose, tablet angle, Hausner ratio, black to white degree L*, red to green degree a*, yellow to blue degree b*] were used to characterize the quality attributes of UGPSMR and to construct the physical fingerprint. Multivariate statistical analysis methods such as similarity analysis, cluster analysis (CA), principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were used to evaluate the quality of 11 batches of UGPSMR (S1-S11) produced in different years, and to find out the difference index between samples from different batches. Result:The method for measuring the particle size distribution and specific surface area of UGPSMR was feasible and repeatable. The similarities between the physical fingerprint of 10 batches of samples (S1-S3, S5-S11) from production and control fingerprint of UGPSMR were above 0.85, but the similarity between sample S4 and the control fingerprint was only 0.488. There were some differences in physical property indicators between different batches of UGPSMR, and the characteristic difference indicators were intergranular porosity, specific surface area, pore volume, b*, L*, Carr index, particle size distribution width, respectively. Conclusion:This method can comprehensively evaluate the physical quality attributes of UGPSMR, and can reflect the effect of differences in material basis of the medicinal materials or production process on the physical properties of finished products, and can evaluate quality consistency between batches from the physical state level, which provides new ideas for the quality control of ultrafine granular powder of herbal medicine.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the relationship between fasting C-peptide (F-CP) and serum uric acid (SUA) in patients with type 2 diabetes mellitus (T2DM).</p><p><b>METHODS</b>A total of 347 hospitalized patients with T2DM were stratified according to F-CP level to analyze the impact of increased F-CP levels on SUA level and the incidence of hyperuricemia (HUA). The patients with an elevated SUA level (>420 µmol/L) and a normal SUA level (≤420 µmol/L) were compared for general data, fasting C-peptide and other clinical indexes. Pearson or Spearman correlation analysis was used to analyze the correlation of SUA level with F-CP levels and other parameters. The risk factors of elevated SUA were analyzed by binary logistic regression, multiple regression analysis and hierarchical interaction analysis. The ROC curve was used to analyze the independent risk factors of elevated SUA and determine the corresponding cut-off values.</p><p><b>RESULTS</b>Compared with those with a normal SUA level, patients with elevated SUA had higher body mass index (BMI), waist-to-hip ratio, F-CP, postprandial 2hC peptide (2hP-CP), triglyceride (TG), homocysteine (HCY), serum creatinine (SCr) level (P<0.05), and a greater percentage of drinking (44.8% vs 32.6%, P=0.006), but had significantly lowered levels of HbA1c, high-density lipoprotein (HDL), and estimated glomerular filtration rate (eGFR) (P<0.05). SUA was found to be positively correlated with F-CP, 2hP-CP, BMI, waist-to-hip ratio, diastolic blood pressure, TG, HCY, SCr, smoking and drinking (P<0.05), and was negatively correlated with gender, age, age of disease onset, HbA1c, HDL and eGFR (P<0.05). SUA level and the incidence of hyperuricemia increasea significantly with F-CP level (P<0.05). F-CP was identified as an independent risk factor for elevated SUA, and gender did not affect the relationship between F-CP and SUA. ROC curve analysis showed that a F-CP level >1.260 ng/mL was associated with a significantly increased risk of hyperuricemia in T2DM patients.</p><p><b>CONCLUSION</b>F-CP is closely related with SUA and may be an independent risk factor of elevated SUA in patients with T2DM.</p>

ABSTRACT

Objective: To explore the effect of tripartite motif 46 (TRIM46) on the proliferation and invasion of colorectal cancer cells and study its possible mechanism. Methods: After TRIM46 siRNA was transfected into human colorectal cancer HCT116 cells, the expressions of TRIM46 mRNA and protein were detected by real-time fluorescent quantitative PCR and Western blotting, respectively. CCK-8 assay and Transwell chamber assay were implemented to observe the effect of TRIM46 down-regulation on the proliferation and invasion of HCT116 cells, and the expression of Src homology 2 (SH2)-containing tyrosine phosphatase 1 (SHP1) was detected by Western blotting. Results: After TRIM46 siRNA was transfected into human colorectal cancer HCT116 cells, the expression levels of TRIM46 mRNA and protein were inhibited (both P < 0.05). Knockdown of TRIM 46 significantly suppressed the cell proliferation and invasion of HCT116 cells (both P < 0.05). However, the expression level of SHP1 was increased (P < 0.05). Conclusion: Ubiquitin ligase TRIM46 may improve the proliferation and invasion of human colorectal cancer cells through suppressing SHP1.

ABSTRACT

Hepatitis B virus (HBV) infection is a worldwide health problem and vertical transmission is the main source of chronic infection in Asian countries. Breakthrough perinatal HBV transmission occurs in 10%-15% of infants born to pregnatal women with high viral load even with appropriate postexposure immunoprophylaxis. Management of chronic hepati?tis B (CHB) during pregnancy remains a challenge, with unique issues that involve prevention of mother-to-child transmis?sion (MTCT) and safe use of antiviral therapy. Previous studies indicate that antiviral therapy with analogs (Lamivudine, Tel?bivudine or Tenofovir) may prevent vertical transmission during late pregnancy in highly viremic mothers. This article sum?marized relevant studies that antiviral therapy in preventing MTCT of hepatitis B virus.

ABSTRACT

The purpose of this study was to investigate the potential cardioprotection roles of Rapamycin in anoxia/reoxygenation (A/R) injury of cardiomyocytes through inducing autophagy, and the involvement of PI3k/Akt pathway. We employed simulated A/R of neonatal rat ventricular myocytes (NRVM) as an in vitro model of ischemial/reperfusion (I/R) injury to the heart. NRVM were pretreated with four different concentrations of Rapamycin (20, 50, 100, 150 μmol/L), and pretreated with 10 mmol/L 3-methyladenine (3MA) for inhibiting autophagy during A/R. Then, Western blot analysis was used to examine variation in the expression of LC3-II, LC3-I, Bim, caspase-3, p-PI3KI, PI3KI, p-Akt and Akt. In our model, Rapamycin had a preferential action on autophagy, increasing the expression of LC3-II/LC3-I, whereas decreasing the expression of Bim and caspase-3. Moreover, our results also demonstrated that Rapamycin inhibited the activation of p-PI3KI and enhanced the activation of p-Akt. It is concluded that Rapamycin has a cardioprotection effect by inducing autophagy in a concentration-dependent manner against apopotosis through PI3K/Akt signaling pathway during A/R in NRVM.

ABSTRACT

Rheumatoid arthritis (RA) and osteoarthritis (OA) are the two most common joint diseases, and they have characterization of synovial inflammation and cartilage destruction, associated with the accumulation of numerous catabolic mediators and inflammatory cells in the synovial space and surrounding soft tissues. How these factors are cleared and if the "clearance" process contributes to pathogenesis of arthritis are not known. Recently, we found the existence of the peri-articular lymphatic system in mouse joints. The blockade of lymphangiogenesis and lymphatic draining function accelerates while stimulation of lymphatic function attenuates the severity of joint tissue lesions in mouse models of RA and OA. More importantly, we noticed the similarity between the dysfunction of lymphatic drainage in arthritic joints and "Bi" theory of Chinese medicine (CM), and demonstrated that several Bi disease-treated herbal drugs directly affect the function of lymphatic endothelial cells. Here we review the advances about the interactions between joint inflammation and changes in the peri-articular lymphatic system and discuss our view of linking "Bi" theory of CM to lymphatic dysfunction in arthritis.
