Objective: The aim of the study is to validate whether the Recognition Of Stroke In the Emergency
Room (ROSIER) scale can be used by general practitioners (GPs) in an emergency medical service
(EMS) protocol to transfer stroke patients from primary care center to advanced hospital with acute
stroke center. Methods: GPs prospectively performed the ROSIER scale and the Cincinnati Prehospital
Stroke Scale (CPSS) on suspected stroke patients as a transfer protocol. All patients were immediately
transferred to the Level-II hospital for further treatment. Results: 468 of the 512 suspected stroke
patients met the inclusion criteria in this study. The ROSIER scale showed a diagnostic sensitivity
of 83.13% (95% confidence intervals [CI] 79.74-86.52%) and specificity of 80.88% (95% CI 77.32-
84.44%). The CPSS showed a diagnostic sensitivity of 78.01% (95% CI 74.26-81.76%) and specificity
of 70.59% (95% CI 66.46-74.72%). The Kappa statistic value of the ROSIER scale and the CPSS
were 0.601 and 0.454, respectively. The area under the curve (AUC) of ROSIER scale was large than
the CPSS (AUC 0.855 vs. 0.791). However, the difference was not significantly different.
Conclusions: This study suggest that ROSIER and CPSS could be used in an EMS protocol to transfer
stroke patients from a primary care center to an advanced hospital offering thrombolysis service

Objective:To study the effect of medical social workers combined with ICU diary on the prevention and treatment of post-traumatic stress disorder in ICU traffic accident patients, and to explore the application of continuing nursing services and ICU diary to ICU traffic accident patients.Methods:A total of 47 patients who were admitted to the ICU of Suzhou Science and Technology City Hospital from January to December 2019 due to traffic accidents were selected by convenient sampling method. Twenty-three patients admitted to the hospital in the first 6 months were selected as the control group (before the introduction of medical social workers and ICU diaries) for routine ICU treatment and nursing mode. Twenty-four patients admitted to the hospital in the last 6 months were selected as the experimental group (after the introduction of medical social workers and ICU diaries), and the medical social workers combined with the ICU diary were intervened. The scores of the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were compared between the two groups of patients when they were admitted to the ICU, stayed in the ICU for a week, and transferred out of the ICU. The incidence of post-traumatic stress disorder was evaluated and compared by the scores of the Impact of Event Scale-Revised of the two groups of patients one month after leaving the ICU, three months after leaving the ICU, and six months after leaving the ICU.Results:The scores of SAS in the experimental group were 58.67 ± 7.45, 44.13 ± 5.47 and 39.08 ± 5.52 when they were admitted to the ICU, stayed in the ICU for a week, and transferred out of the ICU, and were 58.17 ± 6.75, 50.87 ± 6.35 and 42.74 ± 4.85, respectively in the control group. There was no statistical difference in the scores of the SAS between the two groups of patients when they were admitted to the ICU ( P>0.05), but there was a time difference between the two groups with time changes and different interventions ( Ftime = 110.98, P<0.01), there were also differences between groups ( Fbetween groups = 5.91, P<0.05). Compared with the control group, the SAS score of the experimental group decreased more significantly( Finteraction = 0.28, P<0.05). The scores of SDS in the experimental group were 57.75 ± 4.06, 45.29 ± 3.39 and 36.63 ± 3.49 when they were admitted to the ICU, stayed in the ICU for a week, and transferred out of the ICU, and were 57.48 ± 2.29, 49.04 ± 5.65 and 43.57 ± 4.07 respectively in the control group. There was no statistical difference in the scores of the SDS between the two groups of patients when they were admitted to the ICU ( P>0.05), but there was a time difference between the two groups of patients with time changes and different interventions ( Ftime = 248.24, P<0.01), there are also differences between groups ( Fbetween groups = 24.39, P<0.05). Compared with the control group, the SDS score of the experimental group decreased more significantly ( Finteraction=10.44, P<0.05). The incidences of post-traumatic stress disorder in the experimental group were 9, 8, 6 cases at one month, three months and six months after leaving the ICU, which were lower than 12, 11, 8 cases in the control group. The generalized estimation equation showed that the difference was statistically significant ( χ2=4.21, P<0.05). Conclusions:The intervention model of medical social workers combined with ICU diary is conducive to the use of ICU diary and the development of continuous nursing, which improves patients′negative emotions and reduces the incidence of post-traumatic stress disorder.

Malaria is a serio us and life-threatening infectious disease that has a profound impact on human life. Artemisinin is still the first-line drug for clinical antimalarial treatment recommended by the World Health Organization. The antimalarial activity of artemisinin is mainly reflected in the peroxide bridge structure. Artemisinin-based combination therapy (ACT)is the first-line treatment for malaria in many countries. ACT mainly include artemether-lumefantrine ,artesunate-amodiaquine and dihydroartemisinin- piperaquine,etc. Compared with artemisinin monotherapy ,ACT has the advantages of shortening the length of hospital stay , speeding up parasite clearance ,and saving economic costs ,etc. However ,there are still problems such as drug resistance. This article reviews the application status ,advantages and disadvantages of ACT at home and abroad in recent years ,in order to provide ideas for the subsequent screening of long-acting adjuvant antimalarial drugs in ACT and to solve the problem of drug resistance.

Objective To analyze the efficacy and safety of nalbuphine in patients with sedative analgesia in intensive care unit (ICU). Methods A prospective observation was conducted. The adult patients with mild and moderate analgesia in general ICU of the First Affiliated Hospital of Zhengzhou University from January to November in 2017 were enrolled, and they were divided into nalbuphine group and sufentanil group in proper order. The nabobrown group was given 40 mg nabobrown, the sufentanil group was given 0.1 mg sufentanil, both of which were injected with 50 mL normal saline for continuous intravenous infusion in micro-pump. Infusion speed was checked according to pain level. The analgesic target was critical-care pain observation tool (CPOT) score < 2. The change in hemodynamics of patients in both groups were observed, and CPOT score and Richmond agitation-sedation scale (RASS) score were recorded before and l, 3, 5, 12, 24 hours after administration. The analgesic and sedative effects of two drugs were evaluated. Results A total of 141 patients were enrolled, including 71 patients in nalbuphine group and 70 in sufentanil group. There was no significant difference in general data including gender, age, body weight, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) or pain source, as well as baseline hemodynamics parameter between the two groups. At 1 hour and 3 hours after administration, nalbuphine had no effect on blood pressure, but the heart rate was decreased slightly, while the heart rate and blood pressure of the sufentanil group were decreased obviously. The two drugs could make the heart rate and blood pressure fluctuate obviously with the time of medication, but there was no statistical difference between the two drugs. The two drugs had no significant effect on pulse oxygen saturation (SpO2) during analgesia. The average dosage of nalbuphine was 0.03 (0.02, 0.05) mg·kg-1·h-1in the nalbuphine group, and the patient was satisfied with the analgesic effect until 3 hours after the use of the drug, and CPOT score was significantly decreased as compared with that before administration [1.0 (1.0, 2.0) vs. 3.0 (2.0, 4.0), P < 0.01], and the sedative effect was increased, RASS score was significantly lower than that before administration [0 (0, 1.0) vs. 1.0 (1.0, 2.0), P < 0.01]. No patients in naporphine group were treated with sufentanil due to unsatisfactory analgesia. The average dosage was 0.11 (0.06, 0.14) μg·kg-1·h-1in the sufentanil group, the patient was satisfied with the analgesic effect until 5 hours after administration, and the CPOT score was significantly lower than that before administration [1.0 (1.0, 2.0) vs. 4.0 (3.0, 6.0), P < 0.01], and the sedative effect was significantly increased, RASS score was significantly lower than that before administration [0 (-1.0, 0) vs. 2.0 (1.0, 2.0), P < 0.01]. The scores of CPOT and RASS in the sufentanil group were significantly higher than those of the naporphine group before use, so the decrease in the CPOT and RASS scores of the two drugs was further analyzed, which indicated the decrease in CPOT score of naporphine group was significantly lower than that in sufentanil group from 3 hours on [1.0 (0, 2.0) vs. 2.0 (1.0, 3.0), P < 0.05], and the decrease in RASS score of naporphine group was significantly lower than that in sufentanil group from 1 hour on [0 (0, 1.0) vs. 1.0 (0, 2.0), P < 0.01]. It suggested that naporphine could achieve sustained and stable analgesic effect and avoid excessive sedation caused by sufentanil. Conclusions Naporphine had a sustained and stable analgesic effect on patients with mild and moderate ICU analgesia. The onset time of naporphine was equivalent to sufentanil, and it had a certain sedative effect and less influence on hemodynamics.

Viral hepatitis is an important cause of liver cirrhosis and liver cancer, which has become a major public health problem in the world. Traditional Chinese medicine has unique advantages in treating viral hepatitis, which can inhibit virus replication and enhance immunity. It can effectively prevent liver fibrosis and canceration, improving liver function and symptoms significantly with definite clinical curative effects, a high level of safety, and seldom drug resistance. In addition, it reduces the side effects of western medicine, achieving the effect of synergy and attenuation while reducing the recurrence rate of patients after drug withdrawal. Attention has been paid to the research on the treatment of viral hepatitis with traditional Chinese medicine, and great progress has been made in experimental research and clinical practice. In this paper, the research progress of traditional Chinese medicine in the treatment of viral hepatitis at home and abroad in recent five years was systematically reviewed. Modern research has confirmed that traditional Chinese medicine can play a role in the treatment of viral hepatitis by directly or indirectly inhibiting the virus, anti-inflammatory, anti-fibrosis, anti-oxidation, regulating immunity, regulating autophagy, and other signal pathways. In clinics, traditional Chinese medicine compound or combined with western medicine is often adopted to ameliorate the clinical symptoms of patients such as fatigue and loss of appetite, improve the immune mechanism of the body, enhance the antiviral ability, shorten the treatment course of patients and improve their quality of life. The research provides a reference for pharmacological research, clinical research, and new drug development for viral hepatitis.
