Objective To investigate effect of Danhong injection combined with atorvastatin treatment of patients with unstable anginapectoris.Methods Ninety patients with unstable anginapectoris from Mar.2010to Dec.2013 in the First People's Hospital were selected and randomly grouped as control group(n=40) and atorvastatin-Danhong injection group(n =50).All patients in two groups were treated with routine therapy,and patients in the atorvastatin-Danhong injection group were also treated with atorvastatin at dose of 20 mg per day for 15 days and Danhong injection at dose of 30 ml in 250 ml physiological saline per day for 15 days.The level of high-sensitivity C-reactive protdn(hs-CRP) in serum and the haemodynamics of two groups during before and post-treatment were measured and analyzed.Results The effective rate of atorvastatin-Danhong injection group was 84.0％ (42/50),higher than that in control group (70.0％ (28/40),x2 =5.738,P =0.039).The level of hs-CRP in two groups at after treatment were (7.6±2.1) and (3.6±1.7) mg/L,lower than those at pretreatment((1 8.6±4.7) mg/L,(19.2±4.2) mg/L),and the differences were significant (t =8.644,7.848;P =0.004,0.007).Compared with control group after treatment,the level of hs-CRP in atorvastatin-Danhong injection group decreased rapidly (t =6.384,P =0.009).Compared with pre-treatment,the low cut blood viscosity(LCBV),high shearrate blood viscosity(HSBV),plasma viscosity and red cell assembling index in two groups were decreased remarkably(P＜0.05).Compared with control group at post-treatment,the LCBV,HSBV,plasma viscosity and red cell assembling index in atorvastatin-Danhong injection group were significantly declined (t=5.142,4.672,5.738,5.354;P＜0.05).Conclusion Danhong injection combine with atorvastatin improves the haemodynamics in patients with unstable anginapectoris and induce the inflammatory reaction,and it has the better the effects.

Objective:To study the therapeutic effect of bone peptide combined with rifapentin and levofloxacin on bone and joint damage caused by brucellosis.Methods:A prospective study was conducted to select 64 patients with brucellosis bone and joint damage admitted to Shanxi Provincial People's Hospital from January 2017 to June 2021. They were randomly divided into a control group (32 cases) and an observation group (32 cases) using a random number table method. The control group was treated with rifapentin and levofloxacin, while the observation group was treated with bone peptide on the basis of the control group, with a treatment period of 8 weeks, and the peripheral venous blood sample was collected before and after treatment. The visual analogue scale (VAS), activity of daily living (ADL) score, serum C-reactive protein (CRP), procalcitonin (PCT), erythrocyte sedimentation rate (ESR), and cytokines [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6)] levels were compared before and after treatment.Results:The total effective rates of treatment in the observation group and the control group were 90.62% (29/32) and 65.62% (21/32), respectively, with statistically significant differences between the groups (χ 2 = 5.85, P = 0.016). After treatment, the VAS score of the observation group was lower than that of the control group ( t = 8.29, P < 0.001), and the ADL score was higher than that of the control group ( t = 6.77, P < 0.001). Both groups had lower VAS scores after treatment than before treatment in the same group ( t = 21.72, 15.09, P < 0.001), and higher ADL scores than before treatment in the same group ( t = 22.49, 12.54, P < 0.001). After treatment, the levels of CRP, PCT, ESR, TNF-α, and IL-6 of the observation group were lower than those of the control group ( t = 8.11, 10.75, 4.64, 5.11, 4.55, P < 0.001); the levels of CRP, PCT, ESR, TNF-α, and IL-6 in the two group were lower than these before treatment in the same group ( t = 14.21, 21.47, 11.21, 15.07, 9.73, 15.50, 21.30, 7.52, 6.78, 4.93, P < 0.001). Conclusion:The bone peptide combinated with rifapentin and levofloxacin has a good therapeutic effect on bone and joint damage caused by brucellosis, which can significantly reduce pain and cellular inflammatory reactions in patients, and improve their quality of life.

Objective To construct a radiomics model for predicting hematoma enlargement in early hypertensive intracerebral hemorrhage and explore its predictive value.Methods A retrospective collection of 212 patients with hypertensive intracerebral hemorrhage within 6 h of onset,admitted to our hospital from February 2010 to August 2018,was performed.CT examination was performed within half an hour of admission.CT re-examination was performed 24 h after admission to determine whether there was hematoma enlargement.The regions of interest were delineated on the first CT,and 431 image indicators were extracted from the Matlab software.The LASSO regression model was used to screen out the most predictive imaging features,and the selected features and support vector machine classifier (SVM) were used to build the prediction model.Receiver operating characteristic (ROC) curve was used to evaluate the predicted effect of the model.Results After 24 h of admission,the incidence of hematoma enlargement was 18.9％ (40/212).Eighteen imaging ensemble features (including 4 first-order statistics features:standard deviation,kurtosis,uniformity,and variance;one shape-and size-based feature:surface to volume ratio;7 textual features:long run low grey level emphasis,inertia,correlation-angle 90,short run emphasis,correlation-all direction,long run emphasis,and inverse difference moment;6 wavelet features:autocorrelation-3,informational measure of correlation2-3,long run high gray level emphasis-4,short run high gray level emphasis-4,short run low gray level emphasis-7,and sum variance-3) were combined with SVM to establish a prediction model by LASSO regression model.The area under ROC curve was 0.928,enjoying sensitivity and specificity of 92.5％ and 83.5％,respectively.Conclusion The constructed radiomics model is helpful in predicting the expansion of hypertensive cerebral hemorrhage.

Objective:To automatically synthesize Al 18F-fibroblast activation protein inhibitor (FAPI)-74, and explore its value of clinical application. Methods:Al 18F-FAPI-74 was synthesized automatically by the commercial synthesis module CFN-MPS-100, and its yield, radiochemical purity and stability were determined. Sixteen normal Kunming (KM) mice were randomly divided into 4 groups and euthanized at 10, 30, 60 and 90 min after Al 18F-FAPI-74 injection, and the biodistribution was measured. MicroPET/CT dynamic scanning (60 min) was performed in 5 rat pancreatic tumor-bearing BALB/c nude mice to observe the tumor uptake. Al 18F-FAPI-74 PET/CT imaging was performed on 3 volunteers (1 male, 2 females; age: 37, 41, 43 years) to evaluate the clinical application value of Al 18F-FAPI-74. Results:The automated synthesis time of Al 18F-FAPI-74 was about 35 min, with the synthesis yield of (21.34±3.86)% (without attenuation correction, n=5) and the radiochemical purity more than 99%. The radiochemical purity was still more than 96% after placement at 37 ℃ for 6 h. Biodistribution in normal mice and microPET/CT dynamic scanning in tumor-bearing nude mice showed that consistently high uptake in the kidneys and bladder, and the tumor uptake was the highest at 20 min, and the maximum tumor-to-muscle ratio was 3.16±0.01 at 60 min. PET/CT imaging on volunteers showed that there was a small amount of uptake in myocardium, most organs such as the liver and lung had background uptake, and the maximum SUV max of persistent high uptake of tumor was 17.08. Conclusions:Al 18F-FAPI-74 has the advantages of simple synthesis, high yield, stable quality and good imaging performance in mice and volunteers. It is a kind of imaging agent that meets the requirements of clinical diagnosis.
