OBJECTIVE: To investigate the effects of fluticasone on expression of basic fibroblast growth factor and mRNA in allergic rhinitis rats. METHOD: Ninety Sprague-Dawley rats were randomly divided into three groups(n = 30 for each), including AR group, control group and fluticasone treatment group. In this experiment, the rat model of AR was established by the ovalbumin challenge methods. The expression of the protein of basic fibroblast growth factor and mRNA were detected with immunohistochemistry methods and in RT-PCR methods. RESULT: The protein and mRNA expression of basic fibroblast growth factor in nasal tissue was significantly higher in the AR group than that in control group (P < 0.01), and it was much lower in the treatment group than that in the AR group (P < 0.01), but still higher than that in the control group (P < 0.01). The epithelial cell was the chief expression cell. CONCLUSION The basic fibroblast growth factor participates in the pathogenesis of AR, and inhaled fluticasone can significantly inhabit the expression of the protein and mRNA of basic fibroblast growth factor in the chronic stage of AR, thus preventing the airway remodeling.

As a new generation of negative pressure drainage technology, vacuum-assisted closure (VAC) can provide stable and persistent negative pressure, and there are several modes to choose from. VAC plays an important role in closing wounds quickly, controlling infection, promoting angiogenesis, increasing blood flow, and promoting granulation tissue growth of wounds. It is now widely applied in all kinds of acute, chronic, and special wounds in clinic with good therapeutic results. However, we need to pay attention to contraindications and complications of VAC when it is used, avoiding secondary damage due to improper treatment. In this review, we summarize VAC dressings, treating pressure and mode choice, mechanism in promoting wound healing, and clinical application of VAC.

With the prevalence of nonalcoholic fatty liver disease (NAFLD) in the non-obese population, more and more studies have explored the significance of NAFLD in such population. Compared with the patients with obese NAFLD, the patients with non-obese NAFLD lack the phenotype of obesity, but they still have metabolic disorders and higher risk of metabolic and cardiovascular diseases. At present, there are no effective drugs for the treatment of non-obese NAFLD, and the existing treatment methods have their own advantages and limitations in clinical practice. This article reviews the advances in the etiology and treatment of non-obese NAFLD, in order to provide a reference for guiding the clinical treatment of non-obese NAFLD.

Liver cancer is a common tumor that seriously threatens human life and health. Given that the early onset of liver cancer is insidious and lacks specific symptoms, hence it is difficult to screen through routine examination. Thus, clinical diagnosis of liver cancer is mostly in the advanced stage. However, advanced liver cancer has few treatment options, poor prognosis and high relapse rate, thereby causing a high mortality rate. Therefore, early diagnosis of liver cancer is particularly important. Currently, non-invasive screening of liver cancer widely used in clinical setups lacks sufficient sensitivity and specificity, hence, a more reliable diagnostic method needs to be found urgently. This article reviews the research progress of noninvasive early diagnosis of liver cancer to provide a reference for raising the early diagnosis rate of liver cancer.

The sensation of heat-sensitive moxibustion (HSM) refers to the heat feeling at distal and deep part of the body when a patient is treated with moxibustion under unhealthy status, which may even transmits to the disease sites, instead of heat feeling at local and superficial part of the body. Professorhas systema-tically studied the HSM sensation and its clinical laws through clinical practice; he points out different HSM sensations contain different physiological and pathological information of the human body, which could reflex the severity of diseases, so the collection of HSM information should be emphasized; the type and intensity of HSM sensation could guide the clinical acupoint selection and precise localization. The appearance and disappearance of HSM sensation could be applied to establish individual amount of moxibustion, and disappearance of HSM sensation is an appropriate signal for sufficient moxibustion time, which break through the concept of fixed time at each acupoint, and provide measurement standard to make full use of moxibustion. The criteria of indications for moxibustion is proposed, indicating the disease in which HSM sensations appear is the optimal indication. The deep and comprehensive understanding on the generation and change of HSM sensation could improve the standardization of HSM standard technique and its efficacy.

OBJECTIVE: To explore the role of miR-744-5p/CCND1 axis in clear-cell renal cell carcinoma (ccRCC). METHODS: We examined the expression levels of miR-744-5p in 65 pairs of ccRCC and adjacent tissue specimens and in 5 ccRCC cell lines and human renal tubular epithelial (HK2) cells using qRT-PCR. The ccRCC cell lines 786-O and OSRC2 were transfected with miR-744-5p mimic, CCND1 mimic, or their negative control mimics, and the changes in cell proliferation, migration, and invasion were evaluated with CCK-8, wound healing, and Transwell assays. The downstream target molecules of miR-744-5p were predicted by bioinformatics analysis, and the expression level of CCND1 in ccRCC cells was verified by qRT-PCR and Western blotting. The relationship between miR-744-5p and CCND1 was further validated by dual luciferase reporter assay, and the role of the miR-744-5p/CCND1 axis in ccRCC was explored by rescue experiments. RESULTS: MiR-744-5p was significantly downregulated in ccRCC tissues and cell lines (all P < 0.05), and its overexpression inhibited the proliferation, migration, and invasion of ccRCC cells (all P < 0.05). Bioinformatics analysis and dual luciferase reporter assay showed that CCND1 was a downstream target of miR-744-5p. The results of rescue experiments showed that upregulation of CCND1 could partially reverse the inhibitory effect of miR-744-5p overexpression on ccRCC cell proliferation, migration, and invasion (all P < 0.05). CONCLUSION MiR-744-5p inhibits the malignant phenotype of ccRCC cells by targeting CCND1, and the miR-744-5p/CCND1 axis may be a novel target for diagnosis and treatment of ccRCC.

Objective: To explore the predictive values of the modified Baux score, Belgian Outcome in Burn Injury score, and Ryan score on the death risk of severe burn patients. Methods: A retrospective case series study was conducted. From February 2018 to November 2019, 260 severe burn patients who met the inclusion criteria were admitted to the Department of Burns of the First Affiliated Hospital of Nanchang University, including 158 males and 102 females, aged 36 (3, 53) years. According to the final outcome, the patients were divided into survival group (n=229) and death group (n=31). Data of patients were compared and statistically analyzed with chi-square test or Mann-Whitney U test between the two groups, including the gender, age, cause of burn, site of burn, total burn area, depth of burn, combined inhalation injury, and combined underlying diseases on admission, and the modified Baux score, Belgian Outcome in Burn Injury score, and Ryan score calculated based on part of the aforementioned data. The Kendall tau-b coefficient method was used to analyze the consistency of the above-mentioned three scores in 260 severe burn patients. The receiver operating characteristic (ROC) curves of the above-mentioned three scores predicting the death risk of 260 severe burn patients were drawn, and the area under the curve (AUC), the optimal threshold, and the sensitivity and specificity under the optimal threshold were calculated. The quality of AUC of the above-mentioned three scores was compared by Delong test. Results: The gender, site of burn, and depth of burn of patients between the two groups were all similar (P>0.05). The age, total burn area, proportion of flame burn, proportion of combined inhalation injury, and proportion of combined underlying diseases of patients in death group were significantly higher than those in survival group (with Z values of 5.53 and 17.78, respectively, χ² values of 16.23, 15.89, and 17.78, respectively, P<0.01); the modified Baux score, Belgian Outcome in Burn Injury score, and Ryan score of patients in death group were 142 (115, 155), 7 (5, 7), 2 (2, 3), all significantly higher than 64 (27, 87), 1 (0, 3), 0 (0, 1) in survival group (with Z values of 7.91, 7.64, and 7.61, respectively, P<0.01). In 260 severe burn patients, the results between the modified Baux score and Ryan score, modified Baux score and Belgian Outcome in Burn Injury score, Ryan score and Belgian Outcome in Burn Injury score were significantly consistent (with Kendall tau-b coefficients of 0.75, 0.71, and 0.86, respectively, P<0.01). The AUCs of ROC curves of the modified Baux score, Belgian Outcome in Burn Injury score, and Ryan score for predicting the death risk of 260 severe burn patients were 0.92, 0.89, and 0.85, respectively (with 95% confidence intervals of 0.86-0.98, 0.83-0.95, and 0.78-0.93, respectively, P<0.01); the optimal thresholds were 106.5, 4.5, and 1.5 points, respectively; the sensitivity under the optimal threshold were 88.5%, 76.9%, and 73.1%, respectively, and the specificity under the optimal threshold were 88.5%, 87.2%, and 86.3%, respectively. The modified Baux score was similar to Belgian Outcome in Burn Injury score in the AUC quality (z=1.25, P>0.05), which were both significantly better than the AUC quality of Ryan score (with z values of 2.35 and 2.11, respectively, P<0.05). Conclusions: The modified Baux score, Belgian Outcome in Burn Injury score, and Ryan score have good ability in predicting the death risk of severe burn patients. From the perspective of clinical practice, the modified Baux score is more suitable as a predictive tool for the prognosis of severe burn patients.

OBJECTIVETo investigate the influence of lanthanum on lipopolysaccharide (LPS) induced NF-KB activation in murine peritoneal macrophage.

METHODSPeritoneal macrophages were isolated and cultured by routine method, and randomly divided into 5 groups: i. e, control group, LPS group (with LPS stimulation for 30 min), La3+ group (with 2.5 micromol/L La3+ group for 30 min) , La3+ + LPS group( with 1 microg/ml LPS stimulation for 30 min after 30 min incubation with DMEM-F12 containing 2.5 microM of lanthanum.) ; La3+/LPS group (with 2.5 microM of lanthanum stimulation for 30 min, and then with 1 microg/ml of LPS for another 30 min after lanthanum was removed. The location of NF-kappaB p65 subunit (NF-kappaB/p65) in Mphi was detected by immunofluorescence and fluorescence microscope. The binding activity of NF-kappaB/p65 with DNA in nuclei was detected by TransAMTM NF-kappaB/p65 Transcription Factor assay kit. Meanwhile, the expression of NF-kappaB/p65 in nuclei, as well as IkappaBalpha in cytoplasm was measured by Western blotting. TNF-alpha content in culture supernatant were detected by ELISA.

RESULTS(1) The green fluorescence in control, La3+, La3+ LPS and La+/LPS groups was mainly located in cytoplasm, while that in LPS group was located in nuclei. The fluorescent intensity in LPS group was (116 +/- 14), which was obviously higher than that in other 4 groups (42 +/-7,73 +/-30,48 +/- 11 and 67 +/- 19, respectively, P <0.01). (2) The IkappaBalpha protein level in cytoplasm in control (0.048 +/- 0.027), La3+ group (0.062 +/- 0.049), La3+ + LPS group (0.066 +/-0.031) and La3+/LPS group (0.108 +/- 0.017) was significantly lower than that in LPS group (0.435 +/-0.066, P <0.01). (3) The expression and activation of nucleus p65 protein in Mphi in LPS group was obviously higher than the other 4 groups, but changes in the IkappaBalpha expression between LPS group and other 4 groups was of controversy. (4) TNFalpha level in the culture supernatant in La3+ group was lower than that in control group ( P < 0.05) and below the detection limit (25 pg/ml). Moreover, it in La3+ + LPS group and La3*/LPS group was lower than that in LPS group (P <0.01), but higher than that in control group.

CONCLUSIONLPS can activate the nucleus translocation of NF-kappaB/p65 in Mphi of mice, increase NF-KB/p65 expression and activity, but reduce IkappaBalpha protein expression, which lead to increase of TNFalpha secretion. Lanthanum can inhibit lipopolysaccharide induced NF-kappaB activation.
