Methods Cases of severe fever with thrombocytopenia syndrome were collected. The case data from January 2011 to December 2015 were used as the modeling group to establish the death risk model. The case data from January 2016 to December 2016 were used as the validation group to verify the death model. The first time 11 laboratory examination results were selected after admission to ICU for analysis. Through ROC curve, laboratory indexes with area under the curve (AUC)＞0.6 were selected to determine the best cutoff value of each index. Through the logistic regression analysis, the laboratory indexes that had influence on the prognosis were selected, and the original β value was assigned to them. At the same time, after the β value was rounded, the risk model was established and verified, and the sensitivity and specificity of different total scores were analyzed.Results The AUC of ALT, AST, CKMB, Cr, UA, BUM, Ca2+, K+ and Na+ were all >0.60. Logistic regression analysis showed that the increase of AST, K+, and BUN was directly related to the predicted death, respectively. The area under ROC curve was 0.908 and 0.907 respectively. The sensitivity and specificity were 97.6% and 95.2%.Conclusion The simplified scores of AST, K and BUN are of high value in predicting the risk of death in patients with severe fever and thrombocytopenia syndrome. Patients with a total score≥3 should be highly alert to the clinicians. 2020 Vol. 43 (5): 340-343 [Abstract] ( 112 ) HTML (1 KB)  PDF (940 KB)  ( 140 ) 344 Observation of the complications after the myopic surgery corrected by transepithelial photorefractive keratectomy LU Yanfeng, HUANG Xudong DOI: 10.19739/j.cnki.issn1001-9510.2020.05.007 Objective To explore the causes, prevention and treatment of complications in patients after transepithelial photorefractive keratectomy (transPRK).Methods The cases were retrospectively studied.

X-ray lateral cephalograms were taken at pre-and post-orthodontic treatment, and the related variables of chin soft tissues were measured and statistically analyzed.Results After treatment, the LL-B′-Pog′ was significantly reduced in the groups of high-angle and normal-angle in skeletal class Ⅱ and class Ⅲ malocclusion, P＜0.01, but the high-angle group showed a more significant reduction than the normal-angle group, P＜0.05. There were increases in Pog-Pog′, Pog′B′-FH, and B′LL-FH in the group of high-angle after treatment, P＜0.05, whereas the LL-Pog′ showed a reduction, P＜0.01. In the group of low-angle, the LL-E was markedly reduced, P＜0.01. Obvious reductions showed in LL-E, B′LL-FH, and Pog-Pog′ in the group of high-angle in skeletal class Ⅲ malocclusion after treatment, P＜0.05, meanwhile, distinct increases showed in B′-LLPog′ and Pog′B′-FH, P＜0.01. There were no statistical differences in the normal-angle group except the reduction of B′LL-FH, P＜0.01. In the group of high-angle, the skeletal class Ⅲ malocclusion showed a more significant variation than the class Ⅱ malocclusion in the LL-B′-Pog′, Pog-Pog′, and B′LL-FH, P＜0.01, the change of mentolabial angle was more distinct in the skeletal class Ⅲ malocclusion than the skeletal class Ⅱ malocclusion in normal-angle group, P＜0.05.Conclusion The chin soft tissue and lateral appearance tend to be in harmony after orthodontic treatment with extraction in adults. There was a more significant change of the chin soft tissue in the high-angle group on account of orthodontic treatment with extraction, especially in the skeletal class Ⅲ malocclusion. 2020 Vol. 43 (5): 348-352 [Abstract] ( 144 ) HTML (1 KB)  PDF (1153 KB)  ( 196 ) 353 Experimental study of hyaluronic acid combined with metronidazole or periocline in the treatment of chronic periodontitis GUO Wei, WANG Peng, ZHENG Mingxue, WANG Kun, GAO Shuting, YANG Yan DOI: 10.19739/j.cnki.issn1001-9510.2020.05.009 Objective To study the anti-inflammatory effect of hyaluronic acid combined with metronidazole or periocline on chronic periodontitis.Methods The periodontitis model of rats was established. According to the negative control group, the positive control group, the metronidazole group, the hyaluronic acid group, the metronidazole combined with hyaluronic acid group, the periocline group, and the periocline combined with hyaluronic acid group, the rats were divided into 7 groups, with 10 rats in each group. The expression levels of TNF-α and IL-1β protein in gingival crevicular fluid were measured by ELISA 2 h, 6 h, 24 h and 5 d after the treatment, then MMP8 and TIMP1 expressed in gingival epithelium were measured 24 h and 5 d after the treatment.Results Two hours after the treatment, the expression of TNF-α and IL-1 β in all experiment groups was significantly inhibited, P<0.01, especially in hyaluronic acid group, metronidazole combined with hyaluronic acid group, and periocline combined with hyaluronic acid group, P<0.01; 24 hours after the treatment, the inhibition of IL-1 β in metronidazole combined with hyaluronic acid group was significant; 5 days after the treatment, periocline combined with hyaluronic acid group still had a slow inhibition of TNF-α. Twenty-four hours after the treatment, MMP8 expression in all experiment groups showed a downward trend, P<0.01, while the expression of TIMP1 significantly increased, P<0.01, especially in metronidazole combined with hyaluronic acid group, periocline group and periocline combined with hyaluronic acid group; 5 days after the treatment, the expression of TIMP1 in Metronidazole combined with hyaluronic acid group showed an upward trend, P<0.01.Conclusion Local application of metronidazole, hyaluronic acid and Periocline has obvious effect on the early stage of inflammation, but the long-term maintenance effect is not good; the combination of metronidazole and hyaluronic acid, periocline and hyaluronic acid is better than single application. In contrast, the combination of metronidazole and hyaluronic acid has more obvious advantages in five-day continuous anti-inflammatory effect. 2020 Vol. 43 (5): 353-358 [Abstract] ( 158 ) HTML (1 KB)  PDF (2040 KB)  ( 153 ) 359 Diagnostic value of high frequency ultrasound in traumatic neuroma WANG Pingjiao, XU Yongbo, SUN Fang DOI: 10.19739/j.cnki.issn1001-9510.2020.05.010 Objective To study the diagnostic value of high frequency ultrasound in traumatic neuroma.Methods Thirty-two cases with traumatic neuroma were retrospectively collected and analyzed.

They were the multi-modality MRI group (n=201 ) and the color Doppler ultrasound inspection group (n=195 ). The results were analyzed and compared. The multi-modal MRI findings of cervical cancer before and after treatment were compared, and the effect of enhancement on multimodal magnetic resonance imaging was evaluated.Results The diagnostic coincidence rate of multi-modality MRI in detecting stage I and stage II cervical cancer was higher than that of color Doppler ultrasound (P<0.05), but there was no significant difference between the diagnostic coincidence rate of stage III and stage IV. The overall sensitivity of multi-modality MRI to evaluate the staging of cervical carcinoma was 94.6% and specificity was 92.8%. The overall sensitivity of color Doppler ultrasonography was 83.4% and specificity was 82.6%. There was a significant difference between the two (P<0.05). In roc curve analysis, the area of the multi-modal MRI curve was significantly larger than that of color Doppler ultrasonography, and the sensitivity and specificity were significantly higher than that of color Doppler ultrasonography (P<0.05). The accuracy of CR and PR in the evaluation of radiotherapy efficacy in patients with cervicalcancer by multi-modal MRI were lower than that of color Doppler ultrasonography (P<0.05). The enhancement of multi-modal MRI examination was significantly correlated with the evaluation of tumor reduction rate (r=0.649, P<0.01) and radiotherapy effect (r= 0.679, P<0.01). Comparing the multi-modal MRI findings of cervical cancer before and after treatment, it was found that multi-modal MRI could clearly show the size of the tumor and its relationship with the surrounding tissues and organs, and the lesions disappeared after radiotherapy.Conclusion Compared with color Doppler ultrasound, multi-modality MRI is of great value in the accurate diagnosis and staging of cervical cancer and provides a strong basis for the evaluation of radiotherapy effect of cervical cancer. 2020 Vol. 43 (5): 362-366 [Abstract] ( 163 ) HTML (1 KB)  PDF (1107 KB)  ( 161 ) 367 Study on treatment mechanism of heart failure for astragali radix based on network pharmacology DONG Pingping, CEN Shuai, LIU Zihan, WANG Yuqi, DAI Long, WANG Shaoping, ZHANG Jiayu DOI: 10.19739/j.cnki.issn1001-9510.2020.05.012 Objective To study the mechanism of astragali radix against heart failure based on network pharmacology.Methods The potential target of astragali radix against heart failure and signal pathways were predicted by active ingredient screening and target prediction technology, combined with bioinformatics. Finally, we explored the molecular mechanism of astragali radix in the treatment of heart failure.Results Twenty corresponding chemical constituents in astragali radix were screened through the TCMSP data, and 121 targets of these components were found using target prediction technology. Meanwhile, 10 962 known genes related to the occurrence and development of heart failure were retrieved from the gene databases. Eight key targets were selected by string database screening and network topology analysis in Cytoscape software. GO enrichment analysis showed that astragali radix played an important role in anti-heart failure by participating in 10 key signal pathways such as PI3K/AKT, p38MAPK, and MAPK/NF-κB, which were related to 10 biological functions including Cellular energy metabolism response, changes in blood vessel environment, hormone activity, nerve activity and receptor function.Conclusion As a traditional Chinese medicine, the effect of astragali radix against heart failure has the characteristics of multi-component, multi-target and mutual synergy. 2020 Vol. 43 (5): 367-372 [Abstract] ( 175 ) HTML (1 KB)  PDF (2186 KB)  ( 123 ) 373 Study on antioxidant capacity of paeonia extract LI Na, LI Jinlian, LIU Yuling, LUAN Haiyun DOI: 10.19739/j.cnki.issn1001-9510.2020.05.013 Objective To determine the contents of Paeoniflorin in radix paeoniae rubra, and to analyze the antioxidant activities in vivo.Methods Paeoniflorin, an antioxidant component in radix Paeoniae rubra, was extracted by ultrasonic extraction method.

P53 is an important tumor suppressor gene, which inhibits the occurrence and development of tumors by inducing cell cycle arrest, DNA repair and apoptosis, and regulating multiple signal transduction pathways. The cell cycle disorder and the inactivation of signal transduction pathway caused by p53 mutation are factors in the occurrence and progression of many malignant tumors. This article reviews the role of mutationtype p53 (mutp53) in diffuse large B-cell lymphoma and its possible mechanisms. 2020 Vol. 43 (5): 395-398 [Abstract] ( 138 ) HTML (1 KB)  PDF (933 KB)  ( 280 ) Copyright © Editorial Board of 滨州医学院学报 Supported by:Beijing Magtech
