Objective To compare blood pressures results measured by automated sphygmomanometer and standard mercury sphygmomanometer,and to investigate the application of measurements consistency evaluation method in accurate measurement of automated sphygmomanometer.Methods Intraclass correlation coefficient was used to estimate the reliability of repeated measurements,and Bland -Altman method was adopted to evaluate the consistency between automated sphygmomanometer and standard mercury sphygmomanometer.Meanwhile,the results were compared with protocol of European Society of Hypertension.Results The tested automated sphygmomanometer did not adapt to the criteria of European Society of Hypertension.The intraclass correlation coefficient of mercury sphygmomanometer was 0.937 for systolic blood pressure,0.849 for diastolic blood pressure.The intraclass correlation coefficient of tested sphygmomanometer was 0.944 for systolic blood pressure,0.929 for diastolic blood pressure.The 95% consistency interval was(-10.20 to 16.94)mmHg for systolic blood pressure and(-6.25 to 11.69)mmHg for diastolic blood pressure.Conclusion Normally,Bland-Altman method has the same judgment result with protocol of European Society of Hypertension.

Objective To evaluate the efficacy of ultrasound-guided laryngeal mask airway (LMA) in children.Methods ASA Ⅰ and Ⅱ children (aged 1 to 6 years) scheduled for orthopedic surgery of limbs were recruited in this study.ALMA was inserted after induction of general anesthesia.After mechanical ventilation for 5 minutes,the air-filled cuff was deflated and then inflated with saline.Ultrasonography was then performed by a high frequency linear-array transducer to confirm the correct placement of the LMA.Results The LMA can be easily recognized on the transverse view of the thyroid cartilage notch,appearing as a circle around the glottis,which was called the dumbbell sign.On the sagittal view of the thyroid cartilage,the LMA has an archlike appearance which ended below the thyroid cartilage.Oblique scan over the cricoid cartilage shows the tip of LMA is located at the upper portion of the esophagus.Conclusions Filling the LMA cuff with saline instead of air allows better LMA visualization by ultrasound.This method enhances correct positioning of the LMA,which is crucial to ensure safe ventilation.

Objective To show the international protocols for blood pressure monitoring based on a real example. Methods The assessment process of international protocol that can be released by Working Group on Blood Pressure Monitoring of European Society of Hypertension was evaluated. Results 33 participants were selected, which all indexes in evaluation stage one and stage two of the indicators were detected through. The 95% consistency interval in difference between tested device and reference monitor was 10.65~-12.67 mmHg for systolic BP and 13.68~-14.03 mmHg for diastolic BP, and there were 7.1% (7/99) and 6.1% (6/99) of valid points out of the 95% consistency interval. Conclusion The measured automatic blood pressure in the normal environment, measuring accuracy and the standard with the control of mercury -type sphygmomanometer is coincident, so it can be recommended for home application.

AIM: To investigate the relationship betw een ADRP and the development of atherosclerosis. METHODS: Antisense oligodeoxynucleotide of mouse ADRP was constr ucted. The mouse peritoneum macrophages were cultured with Ox-LDL or Ox-LDL plus the antisense fragment. The cellular cholesterol was measured and the expressio n of ADRP was observed with RT-PCR and western blotting. New Zealand white rabbi ts were fed with high cholesterol chow for 12 weeks. The levels of serum lipid a nd cholesterol content of aortic wall were investigated. The areas of fatty stre ak of the aortas was measured after staining with Sudan Ⅳ. The aortic, and live r specimens with HE and immunohistochemistry staining were observed under light microscopes. RESULTS: Antisense oligodeoxynucleotides of mouse ADRP decreased cellular cholesterol ester, induced cellular lipid droplets and the expression of ADRP. The expression of ADRP was induced by high-cholesterol-diet feeding in rabbit atherosclerotic lesions. The fatty streak of the aorta with immunohistoch emistry staining was strongly positive for ADRP in animals fed with high cholest erol chow, and the liver was negative with or without high cholesterol chow. CONCLUSIONS: The expression of ADRP in vessel walls is related t o the atherosclerosis, and has a potential role in lipid accumulation in macroph ages and pathogenesis of atherosclerosis.

Tumor brings great threat to human public health. In recent years, incidence rate and mortality of tumor were rapidly increased in the world. Anti-tumor therapies have undergone the development of cytotoxic therapy, targeted therapy, and immunotherapy. Among them, tumor immunotherapy is rapidly developed and becomes an important anti-tumor therapy in recent years, although it also brings some related side effects. Tumor microenvironment (TME) is composed of immune cells, vascular vessels, fibroblasts, the extracellular matrix, etc. TME significantly affects the efficacy of immunotherapy. Macrophages in the TME are named as tumor associated macrophages (TAMs). Recently, increasing studies have shown that TAMs play an important role in the regulation of tumor immunity, especially in tumor immune surveillance and immune escape. Currently, more and more anti-tumor immunotherapy strategies targeting TAMs are at the development stage. Based on the important role of TAMs in the TME and their potential as therapeutic targets in tumor immunotherapy, we first reviewed the subtypes and functions of TAMs, as well as the roles of TAMs in tumors. Furthermore, we summarized the research progress on anti-tumor strategies targeting TAMs and the current status of drug targeting TAMs. The current review will provide new ideas and novel insights for tumor immunotherapy.

Objective:
To assess the risk of public health emergencies in Zhejiang Province, March 2021.
Methods:
An expert counsel was conducted to assess the risk of coronavirus disease 2019 ( COVID-19 ) , enteritis due to norovirus, chicken pox and influenza by professionals in Zhejiang CDC, based on the information from infectious disease and public health emergency surveillance in Zhejiang Province, domestic health administrative departments, World Health Organization, and European CDC.
Results:
In March 2021, the risk of imported COVID-19 epidemic will be high in Zhejiang Province, and the possibility of local spread could not be ruled out. The possibility of a large-scale outbreak of enteritis due to norovirus and a small-scale outbreak of chickenpox in schools and kindergartens could not be ruled out after the new term begins. An increased risk of influenza epidemic is predicted in collective units such as schools and kindergartens, yet the risk of a large-scale one will be low.
Conclusion
High attention should be paid to COVID-19 and enteritis due to norovirus, and general attention should be paid to chicken pox and influenza outbreak.

Deep skin and soft tissue defects with exposed bone and tendon is difficult to treat, because skin graft rarely survives and flap surgery is sacrifice of donor site. Since "Stage I" membrane was developed by Yannas and Bruke in 1980, numerous kinds of artificial skin have been developed. The adaptability of "Terudermis", developed by the Terumo Co., as an artificial skin composed of sponge made of a fibrillar atelocollagen and a heat-denatured atelocollagen, was clinically evaluated on application to 13 cases presenting deep skin and soft tissue defect with exposed bones and tendons from October 1997 to march 1998. Terudermis has the advantage of allowing early incorporation of fibroblasts and capillaries into its collagen sponge due to very weak dehydrothermal cross-linking. Before Terudermis graft, several days of wet dressing and debridement were required to prepare healthy well-vascularized bed because Terudermis was weak on unsanitary wounds. After bed preparation, Terudermis was grafted like usual skin graft. Tie-over bolster dressing or compressive dressing was used case by case. The dressing was opened 2~3 days after Terudermis grafting. Wet dressing was done daily until the skin graft was done. Autologous skin graft was done 2-3 weeks after Terudermis graft. Our clinical results indicated that Terudermis was beneficial in treating 77% of our patients. Through the use of this new method, treatment of severe skin and soft tissue defects that are usually treated by musculocutaneous or other conventional skin flaps can be replaced by Terudermis as an new artificial dermis.
