Objective To explore the application values and the effect of myocardial preservation of right stellate ganglion block in off-pump coronary artery bypass grafting (OPCABG). Methods Sixty-two patients with ASA Ⅱ or Ⅲ,aged 50-75 years,scheduled for OPCABG were randomly divided into stellate ganglion block group (group SGB)and control group (group C)with 31 cases each.The patients in group SGB received right-lateral SGB before anesthesia induction.The medications and methods of anesthesia induction in the two groups were identical.Hemodynamics be-fore start of anethesia (T0 ),after induction (T1 ),after intubation tube (T2 ),after sternotomy (T3 ),at the beginning of bypass surgery for interrupted coronary artery (T4 ),at the end of coronary bypass grafting (T5 )were observed.Meanwhile,changes of serum cardiac troponin I (cTnI)and cre-atine phosphokinase MB (CK-MB)at T0 ,6 h (T6 ),12 h (T7 ),24 h (T8 )after operation were also observed.The operative time,the amount of drugs used and postoperative recovery were recored. Results MAP,HR of group SGB increased at T2-T5 compared with T0 ,and MAP,HR of group C significantly increased at T2-T5 comparing with T0 (P <0.05).Compared with those in group SGB, MAP,HR significantly increased at T2-T5 in group C (P <0.05 ).The Concentrations of cTnI and CK-MB of group C increased more obviously than those in group SGB at T6-T8 (P <0.05).Compared with group C,patients in group SGB needed less medication,less hospitalization time in ICU and had faster postoperative recovery.Conclusion SGB for patients during OPCABG stabilizes hemodynamy stability,further reduces myocardial injury,thus protecting myocardium.

OBJECTIVE: The intelligent infusion management system is established through intelligent internet of things, by using the gravity sensor, acceleration sensor and other equipment. METHODS: Establish an infusion management platform based on B/S architecture. Combined with the intelligent terminal and get the major values, including:the infusion speed, the remaining liquid and so on. Besides, it can integrate with the HIS, EMR and PDA. RESULTS: It has solved the data collection of the whole infusion process, realized the real-time visualization during the infusion, and improved the quality of nursing management. CONCLUSIONS In the paper, it has been used in wards more than 2 years, which has reduced the workload of the infusion and improved the satisfaction of patients. At the same time, it has provided the infusion big data collection and statistics for the research and auxiliary treatment.

Objective To establish and evaluate chemotherapeutic phlebitis model rats induced by vinorelbine via the dorsalis pedis vein.Methods Rats were divided randomly into control and 4 different concentration of vinorelbine-induced model groups.Control rats were injected with 0.1 mL normal saline via the dorsalis pedis vein of the hind limb,while other rats were injected with different concentrations of vinorelbine(2,3,4,5 mg/mL),as above.General observations were performed and the hind limb volume was measured daily for 7 consecutive days to calculate the swelling rate.The rats were then killed and histological changes in the dorsalis pedis vein were observed by hematoxylin and eosin staining.Microstructural changes on the surface of the vascular endometrium were observed by scanning electron microscopy.Results Injection of 2,3,4,5 mg/mL vinorelbine via the dorsalis pedis vein significantly induced hind limb swelling in a concentration-dependent manner,peaking on day 3 in each group.The phlebitis rates on day 7 were 50%in the 2 mg/mL group and 83.3%in the 3 mg/mL group.Phlebitis was also induced in the 4 mg/mL and 5 mg/mL groups,including grade Ⅲ in 66.6%and grade Ⅳ in 83.3%.Histopathology showed inflammatory cell infiltration,wall thickening,lumen stenosis,and thrombosis in the tissues surrounding the veins.Scanning electron microscopy showed destruction of tight junctions of venous endothelial cells,and a rough surface of the vascular lining,resultsing in blood cell adhesion.Conclusions Injection of 0.1 mL of 3～5 mg/mL vinorelbine via the dorsalis pedis vein could induce red,swollen,and cord-like veins,as well as infiltration of inflammatory cells around the vein,thickened vein walls,lumen stenosis,and thrombosis.In addition,the surface of the venous intima was rough and adhered to numerous blood cells.All these features are consistent with those of clinical chemotherapeutic phlebitis in terms of the symptoms and pathological structure.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.
