Objective To investigate the effect of miR-132-3p on the proliferation of endothelial progenitor cells and its regulatory mechanism in order to provide a new theoretical basis for the treatment of deep venous thrombosis. Methods Real-time quantitative PCR (qPCR) was used to detect the expression of miR-132-3p in the plasma and endothelial progenitor cells of 27 healthy volunteers and 22 thrombus patients, and in endothelial progenitor cells under normoxic and hypoxic conditions. The miR-132-3p analogue and the specific siRNA were transferred into endothelial progenitor cells by the electroporation method. The effect of miR-132-3p on the proliferation of endothelial progenitor cells was detected using MMT and Cell Counting Kit-8 (CCK-8) methods. The effects of miR-132-3p on the expression of FOXO1 in endothelial cells were analyzed using the luciferase assay and western blots. Results The expression of miR-132-3p in clinical patients with thrombosis was significantly decreased to 0.45 ± 0.05 times of that of the healthy volunteers (P＜0.05). The expression of miR-132-3p in endothelial progenitor cells under hypoxia was down-regulated to (0.23 ± 0.13) times of that of under normoxia (P＜0.05). The expression of miR-132-3p of experiment group under hypoxia was up-regulated to (15.72 ± 2.06) times of that of control group (P＜0.05). MMT assay showed that the proliferation of cells in the experimental group under hypoxic condition was up-regulated to (7.79 ± 1.37) times of that in the control group (P＜0.01). CCK-8 assay showed that cell proliferation in experimental group was up-regulated to (6.46 ± 0.38) times of that in the control group (P＜0.01). Software analysis showed that FOXO1 was a direct target of miR-132-3p. Luciferase activity of miR-132-3p mimics transfected endothelial progenitor cells under hypoxic conditions were 0.47 times of that in siRNA treatment group. Western blot showed that the expression of FOXO1 protein in endothelial progenitor cells transfected with miR-132-3p mimics in hypoxia was 0.18 times of that in siRNA treatment group. Conclusions Compared with healthy volunteers, miR-132-3p expression in the blood of patients with thrombosis was significantly reduced that can promote transcription of the FOXO1 gene (and protein expression) and inhibit the proliferation of endothelial progenitor cells. It could be closely related to the formation of venous thrombosis.

Ultrasound-guided radioactive 125I particle implantation for the treatment of advanced gallbladder cancer is susceptible to factors such as ribs, respiratory activity, and biliary reflex, which brings great inconvenience to the operation. We reported one case of gallbladder cancer patients with unclear ultrasound imaging under general anesthesia mechanical ventilation and successful transplantation after sustained inflation with general anesthesia in order to providing basis of clinical diagnosis and treatment.

Objective Taking typical cases of Western medicine as an example,this paper explores the connection between Chinese and Western medicine on the understanding of tongue elephants.Methods After collecting the literature with tongue diagram attached to the clinical imaging column published in NEJM magazine,extracting the symptoms,signs and Western medicine disease information recorded in the literature,the tongue diagram was diagnosed from three aspects:tongue quality,tongue moss and sublingual meridians,and whether the symptoms and signs of tongue correspond to a certain diagnosis result,and the results were analyzed.Results A total of 48 articles were included,including 6 literature on abnormal tongue dynamics,which could correspond to abnormal tongue morphology in traditional Chinese medicine.Thirty-four cases of abnormal tongue shape were found.Among them,12 cases could be diagnosed with corresponding TCM tongue diagnosis,including 7 cases of abnormal tongue shape and 5 cases of abnormal coating.The remaining 22 cases were secondary changes in tongue structure.There were 8 articles on abnormal tongue color,including 1 abnormal tongue color,1 abnormal sublingual chord,and 6 abnormal lichen color.Conclusion Starting from the form and function,explore the connection between Chinese medicine and Western medicine in their understanding of tongue diagnosis,and promote the objectification and standardization of Chinese medicine tongue diagnosis.

Objective:To explore the therapeutic effect of low-intensity extracorporeal shock wave (Li-ESW) in model rats with chronic prostatitis and its optimal parameters.Methods:From April to August 2019, 90 healthy male SD rats aged 8 weeks were randomly divided into control group (group C, n=15), model group (group M, n=15) and shock wave treatment group (group T, n=60), which were treated with Li-ESW after being modeled successfully. The rats in group T were supine and treated with focused Li-ESW, and the probe was placed above the anatomical position of the prostate. Treatment scheme was 3 Hz of frequency, 500 pulses, and once a week for 4 weeks. Group T was divided into group T1(0.09 mJ/mm 2), T2(0.20 mJ/mm 2), T3(0.30 mJ/mm 2) and T4(0.40 mJ/mm 2) according to energy flux density, with 15 rats in each group. Before the establishment of the model, the rats in each group were tested with von Frey fiber of 2 g, 4 g and 6 g at the scrotum respectively, and the positive reaction was recorded. There was no significant difference between the three groups ( P>0.05). After one week, the rat model with CP was established by injecting 3% carrageenan into the bilateral lobes of the prostate under anesthesia. And one week after the modeling was completed, the rats in each group underwent von Frey test again to measure pain and evaluate the modeling effects. Group T was then treated once a week for a 4-week period. During the treatment, von Frey test was performed before each treatment to evaluate the treatment effect of the previous week. After the von Frey test for one, two and four weeks of treatment, 5 rats were sacrificed in each group, and the bilateral lobes of the prostate were dissected under aseptic conditions for paraffin inclusion and HE staining. Result:The positive reaction in group M and each group T was significantly more than those in group C ( P<0.001) one week after the modeling was completed, and there was no significant difference between group M and group T. The number of positive reactions in group T2 was lower than that in group M at each time point after treatment ( P<0.05), and it is also less in group T1, T3 and T4 were than that in group M after 3 weeks, 3 and 4 weeks and 2 weeks respectively( P<0.05). In group T2, the number of positive reactions began to decrease after 1 week of treatment, and reached the lowest after 4 weeks, with significant difference in pain measurement results at different time points ( P<0.05). The results of pathological examination showed that there were more inflammatory cells in prostatic stroma and disordered arrangement of epithelial cells in group M than that in group C. The pathological scores of group M, T1, T2, T3 and T4 were 8, 7, 4, 6, 9 after 1 week treatment, 8, 5, 3, 4, 7 points after 2 weeks treatment, and 7, 3, 2, 4, 7 points after 4 weeks treatment, respectively. Conclusions:Low-intensity extracorporeal shock wave treatment had a significant effect on the improvement of symptoms in model rats with chronic prostatitis. Under the scheme of frequency 3 Hz, 500 pulses, once a week for 4 weeks, the optimal parameters is 0.20 mJ/mm 2.
