Objective To observe the effect of treating acute left heart failure with Shenmai injection and auxiliary conventional western medicine. Methods 132 patients were randomly divided into a control group and a treatment group, with 66 cases in each group. The control group was treated with lanatoside C, captopril, diuretics, and aminophylline. While the treatment group was additionally treated with Shenmai injection on the basis of the control group. Left ventricular ejection fraction(LVEF), left smothering end-diastolic diameter(LVEDD)value, the index of b-type natriuretic peptide(BNP), and 24 h dynamic electrocardiogram(ecg)were observed in both groups after 1 month’s treatment. Results LVEF and BNP were improved in both groups after the treatment[LVEF and BNP were(40.42 ± 4.32)%, (306.57 ± 201.21)pg/ml in the treatment group and(37.92±3.32)%, (451.51±294.23)pg/ml in the control group before the treatment;(35.28±4.15)%, (540.17±382.23)pg/ml in the treatment group and(35.13±2.35)%, (572.35± 422.21)pg/ml in the control group after the treatment], and the curative effect in the treatment group was better than the control group(P<0.05). LVEDD and 24 h average heart rate were also improved in both groups after the treatment [LVEDD and 24 h average heart rate were(59.81±59.81)mm, (79.62±6.38)times/min in the treatment group and(60.91±7.31)mm, (82.61±6.32)times/min in the control group before the treatment;(60.87 ± 7.75)mm, (85.03 ± 7.75)times/min in the treatment group and(61.81 ± 7.35)mm,(86.23 ± 8.35)times/min in the control group after the treatment], but there was no statistical differenc(P>0.05). Conclusion Shenmai injection has good effects in the treatment of acute left heart failure.

Objective:To compare the pharmacoeconomics value of domestic olanzapine with imported olanzapine in the treatment of schizophrenia to provide reference for the rational drug use in clinics. Methods:Two hundred patients with schizophrenia were ran-domly divided into group A ( treated with domestic olanzapine ) and group B ( treated with imported olanzapine ) with 100 cases in each. The treatment course was 8 weeks. The patient’ s condition, adverse reactions, social function, quality of life and daily activity in the two groups were evaluated. Meanwhile, cost-efficacy analysis was performed. Results:The scores of PANSS, SDSS, SQLS and ADL after the treatment were all significantly lower than those before the treatment in both groups (P<0. 01). However, there was no significant difference between the two groups (P>0. 05). In the 2nd and 4th weekend after the treatment, the scores of TESS in group A were all significantly higher than those in group B (P<0. 01). The effectiveness of the two groups was similar. The cost in group A was significantly lower than that in group B(P<0. 01). The efficacy-cost ratio in group A was higher than that in group B(P<0. 01). Conclusion:The domestic olanzapine is as effective and safe as imported olanzapine in the treatment of schizophrenia with lower treat-ment cost. Therefore, the pharmacoeconomics value of domestic olanzapine is much better.

Objective:To investigate impacts of a deep learning image reconstruction (DLIR) algorithm on image quality of lower extremity CTA with low kVp and reverse flow direction scanning.Methods:From January 2021 to March 2021, fifty patients with suspected lower extremities diseases and received lower extremity CTA with low kVp and reverse flow direction scanning in Union Hospital affiliated to Fujian Medical University were retrospectively collected in this study. Six groups of CT images were reconstructed at the thickness of 0.625 mm using two algorithms including ASIR-V of three blending ratios (ASIR-V 20%, ASIR-V 50% and ASIR-V 80%) and DLIR of three strengths (DLIR-H, DLIR-M and DLIR-L). Regions of interest (ROIs) were placed on proximal abdominal aorta (AA), distal AA, left and right common iliac arteries, left and right femoral arteries (upper segment), left and right superficial femoral arteries (middle segment), left and right popliteal arteries. The CT value and SD value were measured for each group; the signal-noise ratio (SNR) and contrast-noise ratio (CNR) were calculated. The lower extremity CTA was divided into four segments, and the subjective evaluation was independently performed on noise and sharpness using 4 points scales by two radiologists. One-way analysis of variance was utilized to evaluate the differences in subjective scoring and objective parameters among the six groups.Results:For all arteries segments, with the increase of blending ratios for ASIR-V and reconstruction strength of DLIR, the SD values were reduced while SNR and CNR were increased (all P<0.05). Among the six groups, DLIR-H and ASIR-V80% images had lowest SD as well as highest SNR and CNR (all P<0.05). In comparison to ASIR-V20% and ASIR-V50% images, DLIR-H images showed lower SD, higher SNR and CNR values (all P<0.05). There were no statistical differences between ASIR-V80% and DLIR-H images in SD, SNR and CNR values (all P>0.05). Subjective scoring results showed that the DLIR-H images displayed the best noise performance for the entire lower extremity arteries from AA to the foot artery, and the sharpness scores of DLIR-H images were also significantly higher than ASIR-V80% (all P<0.05). Conclusion:DLIR can significantly reduce the image noise and improve the image quality in CTA for abdominal aorta to lower extremity arteries. DLIR-H showed the greatest noise reduction ability and the best effect balancing noise and sharpness, providing highest image quality.
