Objective To investigate of the risk factors for the death of severe fever with thrombocytopenia syndrome (SFTS),so as to set up SFTS critical score and evaluate its role in predicting the prognosis for patients with SFTS.Methods A total of 123 SFTS patients hospitalized in Ji′nan Hospital of Infectious Diseases affiliated to Shandong University from June 2011 to October 2014 were enrolled in this study.The univariate Logistic regression analysis was performed to analysis the risk factor for the death of SFTS.Then the SFTS critical score system was set up accordingly.The prognosis value of SFTS critical score was compared with the rapid emergency medicine score (REMS)and the acute physiology and chronic health evaluation Ⅱ (APACHEⅡ)by using receiver operator characteristic curve (ROC).Results Among all the patients,17 males and 14 females were in death group,and 45 males and 47 females were in survival group.The results of the univariate Logistic regression analyses indicated that the glasgow coma scale (GCS),lactate dehydrogenase,activated partial thromboplastin time,oxygen saturation were risk factors for the death of SFTS,with statistically significant difference (all P <0.05). All of the four parameters of SFTS critical scores in the death group were higher than those in the survival group,with statistically significant difference (all P <0.05 ).The REMS,APACHEⅡ score and SFTS critical score in the death group were significantly higher than those in the survival group (all P <0.01 ). The area under the curve (AUC)of REMS,APACHE Ⅱ scores and SFTS critical score were 0.734, 0.746 and 0.788,respectively.The Youden index of the SFTS critical scores was the highest among all three scores (P <0.01).If 15 .0 was used as the cut off value of SFTS critical score,the specificity and the sensitivity for predicting the death risk for the hospitalized patient were 74.2% and 76.1 %, respectively.Conclusion SFTS critical score,REMS and APACHEⅡ score can all effectively predict the prognosis for SFTS patients,among which,the SFTS critical score is the most convenient and has the best predictive value.

OBJECTIVE: To observe the effects of Pollen Typhae total flavone (PTF) on glucose and lipid metabolism in 3T3-L1 adipocytes. METHODS: The content of glucose which disappeared from the culture medium after incubation with drugs for 24 hours was determined as glucose consumption of the cells. The activity of cells was detected by XTT method. The transport of glucose was observed by (3)H-glucose uptake method. The efflux of free fatty acid (FFA) from adipocytes was observed by the concentration of FFA in the culture medium. RESULTS: The glucose concentration in culture medium was significantly decreased with a concentration-dependent effect, when PTF concentrations were from 0.025 g/L to 0.4 g/L. The toxic effect on cells appeared while PTF concentration was 0.4 g/L, and the MTT value decreased. PTF also significantly increased glucose transportation in the 3T3-L1 adipocytes as rosiglitazone (ROS) did. At the same time, FFA concentration in culture medium was significantly decreased as compared to the normal control group, while ROS-treated group did not show any difference. CONCLUSION: PTF can increase insulin sensitivity by increasing glucose transportation and consumption in the 3T3-L1 adipocytes as well as decreasing the FFA efflux from the cells.

In view of the high recognition error rate and long scanning time in the existing hospital scanning technology, a new hospital operating room scanning system is designed based on personal digital assistant (PDA). The PDA scanning device adopts PIC16F877A microcontroller of 8 bit for wireless transmission through RFID and bluetooth technology, the code scanning efficiency is greatly improved. In addition, in order to improve the accuracy of image analysis, this study also adopts the energy driven sampling classification algorithm (EDS-CA) to properly preprocess the medical data information received through PDA scanning, then constructs a function classifier, and improves the image processing efficiency according to the EDS-CA reduction process. The experimental results show that the average accuracy of the code scanning system designed in this study is 95%, which proves that PDA code scanning has good performance.

Objective:To evaluate the clinical efficacy of modified all-arthroscopic reconstruction of medial patella femoral ligament (MPFL) for the treatment of recurrent patellar dislocation.Methods:A retrospective case series study was conducted to analyze the clinical data of 38 patients (46 knees) with recurrent patellar dislocation, who were treated at First Affiliated Hospital of Shenzhen University from January 2017 to January 2020. The patients included 12 males (12 knees) and 26 females (34 knees), aged 14-40 years [(24.6±5.4)years]. All patients underwent the modified all-arthroscopic MPFL reconstruction procedure. The femoral tunnel locations were assessed by 3D-CT immediately after surgery. The MRI was performed at 6 and 12 months after operation to assess the healing morphology of the reconstructed MPFL. The Lysholm score and Kujala score were used to assess the knee function before operation, at 6 months after operation, at 12 months after operation and at the last follow-up. The time to return to sports as well as complications were observed.Results:All patients were followed up for 26-48 months [(32.4±8.6)months]. Postoperative 3D-CT examination showed that the femoral tunnels were located in the groove area of the medial epicondyle of the femur and the adductor tubercle. At 6 and 12 months after operation, MRI T2 images showed that the reconstructed MPFL had a low signal and well tensioned ligament tissue, indicating that the MPFL was healed well. The Lysholm scores at 6 and 12 months postoperatively and at the last follow-up were (81.1±12.0)points, (91.2±3.8)points, and (92.2±9.8)points, respectively, being significantly higher than the preoperative (52.4±10.6)points (all P<0.01). The Kujala scores at 6 and 12 months postoperatively and at the last follow-up were (85.4±3.9)points, (91.4±3.6)points, and (93.1±8.5)points, respectively, being significantly higher than the preoperative (55.2±6.8)points (all P<0.01). Compared with 6 months postoperatively, the Lysholm score and Kujala score were significantly improved at 12 months postoperatively and at the last follow-up (all P<0.05). All patients returned to sports, with the time to return to sports for 3-12 months [(8.7±2.3)months] after operation. One patient had poor wound healing but was healed after dressing changes. No wound infection, nerve injury, joint stiffness, patella re-dislocation or other complications occurred. Conclusion:For recurrent patellar dislocation, the modified all-arthroscopic MPFL reconstruction has advantages of accurate bone tunnel positioning, good ligament healing, good function recovery, early return to sports, and less postoperative complications.

SARS-CoV-2 main protease (M^pro) is one of the most extensively exploited drug targets for COVID-19. Structurally disparate compounds have been reported as M^pro inhibitors, raising the question of their target specificity. To elucidate the target specificity and the cellular target engagement of the claimed M^pro inhibitors, we systematically characterize their mechanism of action using the cell-free FRET assay, the thermal shift-binding assay, the cell lysate Protease-Glo luciferase assay, and the cell-based FlipGFP assay. Collectively, our results have shown that majority of the M^pro inhibitors identified from drug repurposing including ebselen, carmofur, disulfiram, and shikonin are promiscuous cysteine inhibitors that are not specific to M^pro, while chloroquine, oxytetracycline, montelukast, candesartan, and dipyridamole do not inhibit M^pro in any of the assays tested. Overall, our study highlights the need of stringent hit validation at the early stage of drug discovery.

To determine the effect of andrographolide (Andro) on angiogenesis of human umbilical vein endothelial cells (HUVECs).
 Methods: HUVECs were treated with different concentrations of Andro and the cell viability was detected with Cell Counting Kit-8 (CCK-8). HUVECs were treated with half lethal dose (IC50) of Andro. Matrigel was used to make capillary formation of HUVECs and the effect of Andro on capillary formation was evaluated by calculating the percentage of capillary formation. Moreover, the effects of Andro and the supernatant from cultured A549 tumor cells on capillary formation were evaluated by calculating the percentage of capillary formation. The effect of Andro on the expression of matrix metalloproteinase-9 (MMP-9) was determined with Western blot.
 Results: The cell viability of HUVECs decreased with the increase of Andro concentrations. IC50 was 20 μmol/L. The capillary formation of HUVECs was inhibited when treated with 20 μmol/L Andro for 24 hours. Moreover, Andro was able to antagonize the promotion of the capillary formation induced by the supernatant from cultured tumor cells. Andro could suppress the expression of MMP-9 and antagonize the capillary formation.
 Conclusion: Andro inhibits the capillary formation of HUVECs and can antagonize the promotion of angiogenesis induced by the supernatant from cultured tumor cells.
