Objective] Make a research on curative properties from the aspect of zang-fu differentiation in dysuria of Zhang Zhong-Jing. [Methods] Detailly discussed about the properties of dysuria from five aspects: lung, spleen, kidney, triple energizer and bladder. Combine these factors with articles in Treatise on Exogenous Febrile Disease to estimate the condition of body fluid and prognosis of the disease. [Results]The several methods to diagnose and treat dysuria from the idea of Zang-fu Theory, such as ventilating lung and relieving the exterior, invigorating spleen and dissipating excessive fluid, purging and benefiting triple energizer, warming kidney and transforming qi, promoting urination and activating yang. Smooth or not of urine could help to locate the lesion viscera, determine the attribute of deficiency and excess of etiology and judge the prognosis of diseases. [Conclusion]Zhang Zhong-Jing ’s Zang-fu syndrome differentiation theory is an effective way to diagnose and cure dysuria in clinical practices, it is worthy of further research.

Objective To investigate the clinical efficacy of behavioral change stage model management applied in sur-gical patients. Methods All 122 patients who were treated in our hospital from February 2013 to April 2014 were se-lected and divided into the observation group and the control group using the random number table method, with 61 patients in each group. The control group was given conventional nursing, and the observation group was given behav-ioral change stage model nursing. The postoperative pain degree and recovery situation of the two groups were com-pared. Results The observation group was significantly lower than the control group in the first getting out-of-bed time, anal exhaust time and length of hospital stay, the 24-hour sleep time and 48-hour sleep time of observation group was higher than the control group,with statistically significant differences (P<0.05). The postoperative 12-hour,1-day,3-day and 5-day VAS scores of the observation group was significantly lower than the control group, with sta-tistically significant differences(P<0.05). Conclusion Behavioral change stage model can significantly improve surgical patients' life quality,relieve postoperative pain and promote rehabilitation,thereby worthy of further promotion and ap-plication.

OBJECTIVE:To explore an effective method to formulate management-related strategies for off-lable use of drugs by the evidence-based medicine. METHODS:The process of guideline formulation included seven procedures,i.g. establishment ofguideliesformulation workgroup;investigation and selection of the status quo on off-label drug use;identification of the clinical problems;retrieval and evaluation and comprehensing of evidence;applification of GRADE in evidence quality grading;formation of the recommendations consensus;peer review and result publication. And eventually guidelines were formed based on the steps. This study took off-label use of rheumatoid immunoprotective subjects as a case to explore. RESULTS & CONCLUSIONS:Based on the evidence evaluation system and above 7 steps,the methods and process of guideline formulation on off-label use of rheuma-toid immunoprotective subjects that integrated administration,law,clinical medicine,pharmacy subjects were made .The process of guideline formulation fully reflects multidisciplinary characteristics of the workgroup,the advanced nature of the process,the comprehensiveness of evidence ,the rigor of evidence quality grading,and the normalization of consensus. It provides reference in methodology for establishing a comprehensive evidence-based evaluation and management system of off-label use of drugs for all clinical specialist disease. Therefore,this scientific research results may promote the standardization and legalization of the off-label use of drugs management in China.

Objective To investigate the learning curve of contrast-enhanced ultrasonography ( CEUS) in sentinel lymph node( SLN ) of breast cancer and provide a theoretical basis for leaners to learn SLN CEUS . Methods The multi-center study of SLN CEUS in breast cancer" was planned by Sichuan Cancer Hospital . According to the uniform inclusion and exclusion criteria , 511 patients with complete clinical data and follow-up results from 9 hospitals in Multi-center were included in this study . According to the inspection time ,the patients were divided into 3 groups named as group A ( 170 patients) ,group B ( 170 patients) and group C ( 171 patients ) ,respectively . The basic clinical data ,ultrasound imaging data , intraoperative and postoperative pathological findings of all patients were recorded . With the accumulation of cases examined ,analysis was performed to find the learning curve of the SLN CEUS examination time , SLN CEUS detection rate ,SLN CEUS surface marking accuracy rate and SLN CEUS diagnosis rate ,the learning curve was analyzed . Results ① There was no statistical significant difference in patients ages , tumors sizes ,tumors locations ,SLNs numbers and LCs numbers among the three groups( all P > 0 .05) . ②As the number of cases examined increases ,the examination time was reduced gradually ,but SLN detection rate ,surface marking accuracy and SLN diagnostic coincidence rate were increased gradually( F = 151 .75 , 1 .96 ,7 .49 ,5 .50 ; P = 0 .000 ,0 .143 ,0 .001 ,0 .005 ) . Conclusions The skill of the doctor is improved gradually when learning SLN CEUS . With the number of the cases increase ,the operating time of SLN CEUS is shorted ,and the SLN detection rate ,surface marking accuracy and SLN diagnostic coincidence rate of SLN-CEUS are gradually increased . It has an important clinical significance for beginners to learn the SLN CEUS technology .

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has occasioned worldwide alarm. Globally, the number of reported confirmed cases has exceeded 84.3 million as of this writing (January 2, 2021). Since there are no targeted therapies for COVID-19, the current focus is the repurposing of drugs approved for other uses. In some clinical trials, antiviral drugs such as remdesivir (Grein et al., 2020), lopinavir/ritonavir (LPV/r) (Cao et al., 2020), chloroquine (Gao et al., 2020), hydroxychloroquine (Gautret et al., 2020), arbidol (Wang et al., 2020), and favipiravir (Cai et al., 2020b) have shown efficacy in COVID-19 patients. LPV/r combined with arbidol, which is the basic regimen in some regional hospitals in China including Zhejiiang Province, has shown antiviral effects in COVID-19 patients (Guo et al., 2020; Xu et al., 2020). A retrospective cohort study also reported that this combination therapy showed better efficacy than LPV/r alone for the treatment of COVID-19 patients (Deng et al., 2020).

Severe and critically ill patients with coronavirus disease 2019 (COVID-19) were usually with underlying diseases, which led to the problems of complicated drug use, potential drug-drug interactions and medication errors in special patients. Based on ( 6), and -19: , we summarized the experience in the use of antiviral drugs, corticosteroids, vascular active drugs, antibacterial, probiotics, nutrition support schemes in severe and critically ill COVID-19 patients. It is also suggested to focus on medication management for evaluation of drug efficacy and duration of treatment, prevention and treatment of adverse drug reactions, identification of potential drug-drug interactions, individualized medication monitoring based on biosafety protection, and medication administration for special patients.
