Objective To investigate the effects of hepatocyte growth factor(HGF) on proliferation and collagen synthesis induced by angiotensin Ⅱ(AngⅡ)in SD rat cardiac fibroblasts(CFbs),and determine the role it plays in hypertensive ventricular remodeling.Methods CFbs in SD rat were cultured in vitro and treated with different concentrations of AngⅡ and/or HGF.Collagen type Ⅰ synthesis of CFbs was measured by Western blotting,and proliferation of CFbs was detected by MTT assay. Results AngⅡ promoted collagen synthesis and proliferation in CFbs in a certain concentration range,which can be significantly inhibited by HGF. ConclusionHGF can inhibit the proliferation and collagen synthesis induced by AngⅡin SD rat CFbs,and may protect against hypertensive ventricular remodeling.

Abstract： Objective　To investigate the relationship between plasma exosomal microRNA (miRNA)-346 and treatment outcomes in patients with multidrug-resistant tuberculosis (MDR-TB), to provide more reference basis for the treatment of MDR-TB patients. Methods　A total of 406 patients with MDR-TB admitted to Tuberculosis Control and Prevention Institute of Shaanxi Provincial between January 2018 and May 2021 were selected as the study subjects. General clinical data of the patients were collected and analyzed. The expression level of plasma exosomal miR-346 was detected by real-time fluorescence quantitative polymerase chain reaction. The predictive value of plasma exosomal miR-346 for treatment outcome was analyzed using receiver operating characteristic (ROC) curve analysis. Furthermore, the relationship between the expression of plasma exosomal miR-346 and treatment outcome was analyzed using a multivariable logistic regression model. After standard treatment, patients were divided into good treatment outcome group (n=226) and poor treatment outcome group (n=180) according to the treatment outcome. Results　Typical exosomes were identified by transmission electron microscopy, particle size analysis and Western blot, that is, plasma exosomes were successfully extracted. In the poor treatment outcome group, more patients were complicated with diabetes or HIV infection, and the proportion of patients with pulmonary cavity, acid-fast bacilli smear positive rate >1+, previous treatment history and fluoroquinolone resistance was also significantly increased, and the levels of white blood cells, neutrophils, and monocytes were significantly increased, while the level of albumin was significantly decreased, with statistical significance (P>0.05). Compared with the good treatment outcome group [0.61 (0.46, 0.74)], the expression level of plasma exosomal miR-346 in the poor treatment outcome group [1.23 (0.60, 2.02)] was significantly higher (Z=-13.185, P<0.001). ROC curve analysis showed that the area under the curve of plasma exosomal miR-346 to predict adverse outcomes of MDR-TB treatment was 0.881 (95%CI: 0.846-0.915), with a sensitivity of 78.3% and specificity of 86.7%. The corresponding cut-off value was 0.81. Multivariate logistic regression analysis showed that diabetes, AIDS virus infection, pulmonary cavity, AFB smear positive degree>1+, previous treatment history, fluoroquinolones resistance and high expression of plasma exosomal miR-346 were independent influencing factors for poor treatment results of MDR-TB (P<0.05). Conclusions　High expression of plasma exosomal miR-346 is associated with the high risk of adverse outcome of MDR-TB treatment, and it is promising to be a useful marker for predicting the outcome of MDR-TB treatment.

OBJECTIVETo explore the viral and host causes of hepatosteatosis in Chinese patient with chronic hepatitis B.

METHODSA total of 562 patients (450 males and 112 females, age range 13-80 years) with biopsy-proven chronic hepatitis B were enrolled in the study. The patients were divided into two groups: group without steatosis (460 patients) and group with steatosis (102 patients). The groups were compared in terms of age, gender, body mass index (BMI), liver enzymes, cholesterol, triglyceride, APO-A, APO-B, urine acid (UA), fasting serum glucose (FSG) and HBeAg, viral load.

RESULTSSteatosis was present in 102 patients (18.15%). The degree of liver steatosis in 97 (95.10%) patients were less 30%. Steatosis was found in 98 (21.78%) of male patients and 4 (3.75%) of female patients (P < 0.01). In the group of chronic hepatitis B with steatosis, the prevalence of obesity, diabetes mellitus, dyslipidaemia, alcoholic consumption, the BMI, cholesterol, triglyceride, UA and FSG levels were significantly higher than those in the group without steatosis (P < 0.01). No significant difference was found in the mean age, HBeAg, viral load between the two groups (P > 0.05). Logistic regression analysis demonstrated that the present of steatosis was positively correlated to BMI, TG and UA.

CONCLUSIONHepatosteatosis in chronic hepatitis B appears to be a result of metabolic factors of the host rather than the effect of viruses.

Objective To discuss the value of diffusion-weighted MRI (DWI) and 18F-FDG-PET/CT in assessing the early therapeutic effect of radiofrequency ablation (RFA) for VX2 sarcomas in experimental rabbits. Methods VX2 sarcoma was inoculated at bilateral hind limbs in 14 New Zealand white rabbits to establish the animal models. The implanted VX2 tumor on one hind leg was treated with ultrasound-guided percutaneous RFA (study group), while no RFA was given to the VX2 tumor on the contralateral hind leg (control group). DWI-MRI was performed at 2 days after RFA, and 18F-FDG-PET/CT examination was employed at 3 days after RFA. The mean apparent diffusion coefficient (ADC) values and standard uptake value (SUV) of the untreated tumor and the ablated tumor were separately calculated. Taking the pathologic result as the gold standard, the consistency of DWI-MRI, PET/CT as well as the combination of DWI-MRI and PET/CT with the clinical diagnosis was separately evaluated by Kappa test. Results Before RFA, DWI-MRI demonstrated that the VX2 tumor was characterized by hypo-intensity signal on T1 and hyper-intensity signal on T2 with ring-shaped enhancement on T1-weighted image; PET/CT showed that the tumor had nodular or ring-shaped 18F-FDG accumulation. After RFA, DWI-MRI revealed that the VX2 tumor was manifested as hyper-intensity signal on T1 and slight higher density on T1 with slight enhancement on contrast-enhanced T1-weighted image; PET/CT showed lowered accumulation of 18F-FDG. The mean ADC value of the ablated tumor was (1.52 ± 0.24) × 10-3 mm2/s, which was obviously higher than that of the un-ablated tumor, that was (1.09 ± 0.12) × 10-3 mm2/s, the difference was statistically significant(P<0.05). The mean SUV value of the ablated tumor was (0.6 ± 0.3), which was significantly lower than that of the ablated tumor (9.6 ± 3.2, P<0.05). No significant difference in sensitivity, specificity and accuracy existed between DWI-MRI and pathology as well as between PET/CT and pathology, the Kappa value being 0.357 and 0.428 respectively (P>0.05). The Kappa value of the consistency between combination of DWI-MRI with PET/CT and pathology was 0.786, which was significantly different from the result by simple DWI-MRI or simple PET/CT evaluation (P< 0.05). Conclusion Both ADC value of DWI-MRI and SUV value of PET/CT are useful indexes for evaluating the early therapeutic effect of RFA. Both DWI-MRI and PET/CT have their respective advantages, nevertheless, combination use of both can effectively improve the evaluation of curative effect for VX2 tumor after RFA in experimental rabbits.
