Objective: To investigate the diagnostic values of separated renal multi-locular cystic lesions color Doppler ultra-sound and contrast-enhanced ultrasound performance in multi-locular cystic renal cell carcinoma and cysts. Methods:A total of 53 pa-tients (54 lesions) with multi-locular cystic renal cell carcinoma and cysts were included in the study. The presence of carcinoma and cysts was confirmed via histopathology and tested using ultrasound. Contrast-enhanced ultrasound was applied in 24 (24 lesions) of the total number of patients, and the receiver operating characteristic (ROC) curve was used to analyze the numbers of separation, thick-ness, and type of blood flow patterns of the lesions. The contrast-enhanced ultrasound characteristics were also analyzed. We analyzed the diagnostic value of the color Doppler ultrasound in the separated renal multilocular cystic lesions and the contrast-enhanced ultra-sound performance in multi-locular cystic renal cell carcinoma and cysts. Results:Based on the analysis of the ROC curves of the sepa-ration number, thickness, and type of the blood flow of the lesions in 53 patients (54 lesions), the diagnostic specificity was relatively higher in the lesions where the separation number was≥5 strips (86%), the thicknesses were>3 and≤4 mm (95%), and blood flow was band-like (86%). The areas under the curve of the three indexes were 0.7621, 0.8331, and 0.7962, respectively, which indicate high diagnostic values. The separation number of 4 strips, the thicknesses of>2 and≤3 mm, and the point-like blood flow could be used as critical values for the diagnosis. The contrast enhancement, enhancement peak, and disappearance were (11.2 ± 3.4), (21.7 ± 3.8), and (32.1±4.0) s in 14 patients with multi-locular cystic renal cell carcinoma and (18.4±4.5), (37.8±8.0), and (51.3±9.0) s in 10 patients with multi-locular renal cysts, with statistically significant differences (t=4.47, t'=5.90, t'=6.31, respectively;P<0.05). Conclusion:The sepa-ration number, thickness, and type of blood flow of lesions have relatively higher specificity in multi-locular renal cysts than in multi-locular cystic renal cell carcinoma. The ROC curves show a high diagnostic value. Contrast-enhanced ultrasound of the lesions helped in the differential diagnosis of multi-locular cystic renal cell carcinoma and renal cysts.

Objective By comparing clinical efficacy of percutaneous vertebroplasty with high viscosity bone cement and percutaneous kyphoplasty with conventional low viscosity bone cement for osteoporotic vertebral compression fractures,to explore the clinical value of treatment of osteoporotic vertebral compression fractures with high viscosity bone cement.Methods In this prospective study,100 patients with one-level OVCF and older than 70 years were diagnosed and treated in our hospital from June 2014 to December 2015,which were randomly divided into 2 groups (50 patients in each),applied unilateral percutaneous vertebroplasty with high viscosity bone cement and bilateral percutaneous kyphoplasty with conventional low viscosity bone cement,respectively.Collected data of basic clinical informations (including age,gender,body mass index,etc.),preoperative and postoperative visual analog scales (VAS),Oswestry disability questionnaire (ODI),operative time,intraoperative X-ray times,the amount of bone cement injection,leakage of bone cement,anterior vertebral height and kyphosis (Cobb angle) of preoperative and postoperative,and statistical analysis.Results There were significant improvement of both VAS and ODI scores of the postoperative 1 day,3 months and 12 months compared with preoperative,but there was no significant difference between two groups;The operative time,intraoperative fluoroscopy times,bone cement injection amount and intraoperative bone cement leakage of high viscosity bone cement PVP group were significantly less than those of low viscosity bone cement PKP group (P＜0.05);the anterior vertebral height and kyphosis improved,and there was a significant difference between preoperative and postoperative of low viscosity bone cement PKP group (P＜0.05).Conclusion The efficacies of unilateral PVP with high viscosity bone cement and bilateral PKP with conventional low viscosity bone cement for osteoporotic vertebral compression fractures are the same,which can relieve pain and improve function of life significantly.However,the high viscosity bone cement PVP is simpler surgical procedure,with shorter operative time,less intraoperative radiation,less bone cement leakage rate.The domestic bone cement injection device can significantly reduce the cost of surgery,it worth to be widely used for clinical application.

Objective To find the spectacular indexes in the diagnosis of acute rejection of renal transplantation with color Doppler ultrasonography. Methods Forty-two patients with renal rejection were confirmed with percutaneous needle biopsy and 115 patients with stable renal function were confirmed with following-up (>1 year) and clinical examination. The length, width, thickness, cortex thickness and resistive index (RI) of two groups were analyzed statistically. Then the specificity, sensitivity, misdiagnosis rate, false negative rate and consistency rate of renal volume, pyramid swelling, echo weakening, RI＜0.7, RI≥0.7 and RI≥0.8 were calculated. Results The length, width and thickness were statistically different in two groups (P＜0.05). In patients with renal rejection, the marginal blood vessels in renal cortex decreased, and the blood velocity reduced obviously in the diastolic phase and RI increased obviously (P＜0.05). The sensitivity of the above indexes were 55.30%, 55.20%, 42.10%, 57.90%, 31.60%, respectively, while the specificity were 71.30%, 87.10%, 25.70%, 74.20% and 98.20%, respectively. Conclusion Enlargement of renal volume, swelling of renal pyramids, echo weakening and RI increasing are specific indexes for diagnosis of acute rejection of renal transplantation.

Background: Guben Zhike decoction (GBZKD) is derived from the experience of Professor Enxiang Chao, an esteemed master of Chinese medicine, while treating chronic obstructive pulmonary disease (COPD). GBZKD reinforces the healthy qi and consolidates defensive qi. This study explored the efficacy and potential mechanism of action of GBZKD in a COPD mouse model using proteomics.Methods: A COPD mouse model was established through cigarette smoke exposure and intranasal lipopolysaccharide administration. The model was verified through lung function test and lung histo-pathological observation. Label-free quantitative proteomics was used to detect the lung tissue proteins of mice from the GBZKD, COPD, and control groups. Results: GBZKD markedly improved the lung function and associated pathological conditions in the COPD mouse model. Proteomic analysis identified 4316 proteins, of which 3696 were quantitative proteins. We highlighted 287 and 184 proteins with significant regulatory roles in the lung tissues of COPD mice and GBZKD-treated mice, respectively. These proteins participated in multiple functions, including complement/coagulation cascade, immune response, and metabolic pathways. Conclusion: GBZKD exhibits multitarget and multipathway therapeutic effects in a COPD mouse model.

ObjectiveTo explore the mechanism of Jiebiao Qingli decoction （JQD） in treating pneumonia caused by influenza A virus （IAV） infection. MethodsA total of 132 Balb/c mice were randomly assigned into normal control （NC）， model control （IAV）， oseltamivir （OSV， 37.5 mg·kg^-1）， and high-， medium-， low-dose JQD （H-， M-， and L-JQD： 6.05， 3.02， and 1.51 g·kg^-1， respectively） groups. The NC group was treated with normal saline nasal drops， and the other groups were intranasally inoculated with A/Brisbane/02/2018 （H1N1） ［pdm09-like virus （H1N1）］ for the modeling of IAV infection. Two hours post-modeling， the NC and IAV groups were administrated with normal saline by gavage， while other groups received corresponding drugs for 7 d. The body mass， survival status， and deaths of mice were recorded daily during the administration of the drugs. On days 3 and 7， the lung index was measured for mice in each group. Pathological changes in the lung tissue were observed via hematoxylin-eosin staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was conducted to measure the viral load （IAV-M） and the mRNA levels of Toll-like receptor 7 （TLR7）， p38 mitogen-activated protein kinase （p38 MAPK）， and nuclear factor-kappa B （NF-κB） in the lung tissue. Western blot was employed to measure the protein levels of p38 MAPK and NF-κB. Enzyme-linked immunosorbent assay was used to quantify serum levels of interleukin-2 （IL-2）， interleukin-6 （IL-6）， and tumor necrosis factor-alpha （TNF-α）. ResultsCompared with the NC group， the IAV group showed reduced survival quality and survival days （P<0.01）， lung congestion， inflammatory cell infiltration， elevated lung index （P<0.01）， increased viral load （P<0.01）， upregulated TLR7， p38 MAPK， and NF-κB levels （P<0.05， P<0.01）， decreased IL-2 level （P<0.01）， and elevated IL-6 and TNF-α levels （P<0.01）. Compared with the IAV group， H-JQD prolonged survival days （P<0.05）. All JQD groups alleviated pathological changes in the lung tissue and reduced the lung index （P<0.01）. M-JQD and H-JQD decreased the viral load （P<0.01）. H-JQD downregulated the mRNA levels of TLR7， p38 MAPK， and NF-κB （P<0.05， P<0.01） and the protein levels of p38 MAPK and NF-κB （P<0.01）， increased the serum IL-2 level （P<0.01）， and lowered the IL-6 and TNF-α levels （P<0.05， P<0.01）. M-JQD downregulated the mRNA level of NF-κB （P<0.01） and the protein level of p38 MAPK （P<0.05）， elevated the IL-2 level （P<0.01）， and lowered the TNF-α level （P<0.01）. ConclusionM- and H-JQD can prevent and control IAV infection-induced pneumonia dose-dependently by inhibiting the TLR7/MAPK/NF-κB signaling pathway， increasing IL-2， and reducing excessive secretion of IL-6 and TNF-α.
