Objective:To establish a set of comprehensive appraisal indicator system for the full-time scientific research personnel in Level-three general hospitals, improve the management of full-time scientific research personnel at hospital.Methods:Firstly, an initial indicator system was established by literature review and in-depth interviews with experts. Secondly, Delphi method was used to screen the indicators to confirm the indicator system. Finally, Analytic Hierarchy Process (AHP) was used to determine the weights of indicators at all levels, consistency tests were also conducted.Results:A set of comprehensive appraisal index system for full-time scientific research personnel in Level-three general hospitals was established, including four first-level indicators, which covered the comprehensive quality, scientific research capacity, scientific research performance and academic impact, as well as other 17 secondary indicators and 53 third-level indicators. Among these indicators, the scientific research performance has the largest weight value (0.5224), and according to the consistency test results, CR was less than 0.1. Besides, through the consistency test, the weight assignment is reasonable.Conclusions:The appraisal index system of full-time scientific research personnel in Level-three general hospitals is reliable. It can be used as a tool for evaluation of full-time scientific research personnel, which also provide reference for other hospitals to improve the management of full-time scientific research personnel.

Intrahepatic cholangiocarcinoma (ICC) is a malignant liver tumor derived from the epithelial cells of the second- or higher-order branch of the bile duct, with the features of insidious early symptoms, high degree of malignancy, rapid disease progression, lymph node metastasis, intrahepatic metastasis, and vascular invasion, and such patients tend to have poor prognosis. Early diagnosis can improve the radical resection rate and prognosis of ICC. At present, the preoperative diagnosis of ICC mainly relies on imaging technology, laboratory examination, and pathological examination. In addition, some new diagnostic methods have also been used in the diagnosis of ICC in recent years, but histopathological examination remains the only method for the diagnosis of ICC. This article reviews the latest research advances in the diagnosis of ICC.

Objective: To investigate the effects of exposing Trichophyton rubrum fungus to microwaves at different intensities in terms of the activity of succinic dehydrogenase and beta-(1, 3)-D-glucan synthase. Methods: Trichophyton rubrum organisms were randomly divided into a control group and experimental groups. The experimental groups were incubated at 27 ℃ after direct radiation with 2450 MHz microwaves at 20, 40, 60 or 80 W for 15 min, repeated 8 times. The control group was incubated without any irradiation. Thirty days later, the beta-(1, 3)-D-glucan synthase and succinate dehydrogenase activities were determined using enzyme-linked immunosorbent assays. Results: The enzymatic activity decreased gradually with increasing radiation intensity. When the output power was 80 W, the beta-(1, 3)-glucan-synthase-D activity was 0.730±0.74 U/ml and that of the succinate dehydrogenase was 1.828±1.774 U/L, both significantly lower than in the groups subjected to less powerful irradiation. Conclusions Microwave radiation can decrease the enzymatic activity of Trichophyton rubrum in a dose-dependent manner. Higher intensity is more effective. Microwave irradiation can decrease the activity of succinate dehydrogenase and beta-(1, 3)-glucan synthase from Trichophyton rubrum in vitro, resulting in the destruction of fungal cell walls and interfering with the tricarboxylic acid cycle, furthering cell death. Moreover, the temperature change possibly also helps promote the biological effects of microwave radiation.

Objective To compare the effects of ticagrelor and clopidogrel on levels of inflammatory factors after emergent percutaneous coronary intervention (PCI) combined with thrombus aspiration in patients with acute myocardial infarction (AMI). Methods Two hundreds and sixteen patients with AMI undertaking emergent PCI plus thrombus aspiration admitted to Cangzhou Central Hospital from April 2014 to April 2017 were enrolled, and they were randomly assigned into a ticagrelor group and a clopidogrel group, each group 108 cases. After admission, the clopidogrel group received 300 mg aspirin and 300 mg clopidogrel loading, after operation, aspirin 100 mg and clopidogrel 75 mg were given, once a day maintaining for 12 weeks; ticagrelor group after admission received 300 mg aspirin and 180 mg ticagrelor loading and after operation 100 mg aspirin (once per day) and 90 mg ticagrelor (twice per day) were given, maintaining for 12 weeks. Venous blood was taken immediately after admission and 24 hour and 1, 4, and 12 weeks after PCI plus thrombus aspiration, and the plasma levels of C-reactive protein (CRP), interleukin-6 (IL-6) and soluble CD40 ligand (sCD40L) were measured by double antibody enzyme linked immunosorbent assay (ELISA). Results Twenty-four hours after the operation, the levels of inflammatory factors, CRP, IL-6 and sCD40L were significantly higher than those before operation, the levels of the above inflammatory factors continued to decrease at the time points 1, 4, and 12 weeks later, reaching the lowest level at 12 weeks, and the above levels in ticagrelor group were significantly lower than those in clopidogrel group [CRP (μg/L): 2.96±0.63 vs. 4.44±0.34, IL-6 (ng/L): 2.50±0.51 vs. 2.81±0.21, sCD40L (ng/L): 519.60±12.53 vs. 570.25±11.55, all P < 0.05]. Conclusion The anti-inflammatory effect of ticagrelor is greater and more durable than that of clopidogrel after emergent PCI plus thrombus aspiration in patients with AMI.

Intrahepatic cholangiocarcinoma is the second most common intrahepatic primary liver tumor after hepatocellular carcinoma (HCC).Epidemiological study suggests a strong correlation between HBV infection and ICC development.This review focused on the potential mechanisms of HBV-induced ICC and gives a primary summary of suggested hypothesis,which included:(1) HBV infection of liver stem/progenitor cells will indirectly lead to HBV infection of intrahepatic biliary epithelial cells and lead to the development of ICC; (2) the changed microenvironment of intrahepatic biliary epithelial cells by HBV infection eventually results in carcinogenesis ; (3) the HBV infection of hepatic sten/progenitor cell can transform into tumor-like stem cells and ultimately differentiate into ICC-like tumor cells.

Aim To investigate the mechanism for the inhibitory effect of hydrogen sulfide on the expression of tissue factor(TF)induced by oxidative low-density lipoprotein(ox-LDL)in endothelial cells.Methods Human umbilical vein endothelial cells (HUVECs ) were treated with 50 mg·L-1 ox-LDL in the absence or presence of different concentrations of NaHS (25 , 50,100 and 200 μmol·L-1 )for 24 h.The mRNA expression and protein content of TF in HUVECs were determined by reverse transcription PCR and ELISA, respectively.The content of intracellular reactive oxy-gen species (ROS)was determined by DCFH,an oxi-dative sensitive fluorescent indicator.The activation of nuclear factor-kappaB (NF-κB)was estimated by its expression in nuclear extracts analyzed by Western blot.Results Ox-LDL induced TF mRNA expression and increased TF protein content in HUVECs.The in-crease in intracellular ROS production and the activa-tion of NF-κB were observed in HUVECs treated with ox-LDL.However,NaHS could markedly inhibit the increases in TF mRNA and protein levels induced by ox-LDL.Also the elevation of intracellular ROS pro-duction and the activation of NF-κB elicited by ox-LDL were significantly suppressed by pretreatment with NaHS.In addition,pretreatment with BAY 1 1-7082 (10 μmol·L-1 ),the inhibitor of NF-κB or N-acetyl-L-cysteine(1 mmol·L-1 ),an antioxidant,could also decrease the TF mRNA and protein level as well as ROS production and NF-κB activation induced by ox-LDL in HUVECs,similar to the effects of 200 μmol· L-1 NaHS.Conclusion The mechanism for the in-hibitory effect of H2 S on the ox-LDL- induced TF ex-pression in endothelial cells may be related to inhibi-ting intracellular ROS production and subsequently NF-κB activation.

BACKGROUND:Occluder closure of atrial septal defect exhibits clear function, safety and efficiency advantages ＜br> OBJECTIVE:Using real-time three-dimensional echocardiography (RT-3DE) technique to evaluate the effect of atrial septal defect occlusion using different occluders on left ventricular structure and motion of the mitral annulus. ＜br> METHODS:Thirty-seven cases diagnosed as atrial septal defect underwent atrial septal defect occlusion, including 20 males and 17 females, aged 20-60 years. The occluder was chosen individual y according to defect size and edge hardness. Conventional and RT-3DE examinations were performed at 1 day prior to occlusion, 1 and 3 months after occlusion. ＜br> RESULTS AND CONCLUSION:Four of 37 patients were withdrawn from the study because of poor RT-3DE results. The other 33 patients harvested good occlusion results. At 1 and 3 months after occlusion, left ventricular end diastolic volume, left ventricular end systolic volume, left atrial end diastolic volume, left atrial end systolic volume were significantly increased (P＜0.05). Moreover, the more increase in these parameters occurred at 3 months after occlusion (P＜0.05). There were no significant changes in left ventricular ejection fraction and mitral annular displacement at three different time points. Left ventricular volume change rate and left atrial volume change rate were positively correlated to the type of occluders, while there was no correlation between endocardial cushion stump and mitral annular displacement. These findings suggest that atrial septal defect occlusion can increase the volume of the left ventricle and left atrium, but exhibit no effect on the motion of the mitral annulus.

BACKGROUND:The treatment of severe rigid idiopathic scoliosis is the difficulty of clinical treatment. The studies in recent years have shown that the three-stage correction is a safe and effective treatment method. OBJECTIVE:To explore the efficacy of three-stage correction in the treatment of severe rigid scoliosis. METHODS:Retrospective analysis was performed on 10 severe rigid scoliosis patients undergoing three-stage correction, the mean age of the patients was 12 years. The average Cobb angle in the coronal plane was 140° (ranged 110°-180°), the average Cobb angle in the sagittal plane was 75° (ranged 50°-100°). The treatment was divided three stages:anterior release, Halo-plevic traction and third step with posterior osteotomy and fixation. RESULTS AND CONCLUSION:Al of the patients underwent the surgery safely without severe complications. After anterior release and Halo-plevic traction, the Cobb angle in the coronal plane was 90°, and the mean correction rate was 35.7%;the Cobb angle in the sagittal plane was 50° with correction rate of 33.3%. The mean Cobb angle in the coronal plane was 40° with the correction rate of 71.4%after osteotomy, and the Cobb angle in the sagittal plane was 35° with the correction rate of 53.3%. The results show that three-stage correction is a safe and effective method for the treatment of severe rigid scoliosis.
