Happy medical treatment" is a new idea of the hospital. On the one hand, it stresses that the hospital should strive to reduce the pain and increase the happiness of patients; on the other hand, it pursues the goal of medical personnel working happily and enjoying happiness in their work. The creation of the idea of "happy medical treatment" results inevitably from the increasingly intensifying competition in the medical market and from the constantly rising expected value on the part of consumers. By explaining the connotations of the idea of "happy medical treatment", the paper sets forth the basic principles for the hospital to develop the new idea: permeability, systematicness and continuity. An in-depth analysis on these principles is offered.

Objective To analyze the efficacy and safety of amiodarone in the treatment of patients with tachyarrhythmia in emergency department.Methods The clinical data of 112 patients with emergency tachyarrhythmia admitted to the Emergency Department of the First People's Hospital of Jinzhong from March 2017 to March 2018 were analyzed.According to the different treatment plans applied,the patients were divided into two groups,with 56 patients in each group.The control group was given routine emergency treatment,and the observation group was treated with routine emergency treatment and amiodarone.The efficacy,blood pressure,heart rate and safety in the two groups were compared.Results The total effective rate in the observation group was 91.07％,which was higher than that in the control group(69.64％) (x2 =8.145,P ＜ 0.05).The diastolic blood pressure,systolic blood pressure and heart rate in the observation group were (77.40:±:6.21) mmHg,(124.24 ± 6.15) mmHg and (130.18 ± 6.14) beats/min,respectively,which were lower than those in the control group[(93.47 ± 7.40)mmHg,(140.60 ± 7.48)mmHg and (150.35 ± 12.32) bests/main] (x2 =8.145,t =12.448,12.642,10.966,all P ＜ 0.05).The total incidence rate of adverse reactions in the observation group was 3.57％,which was lower than 19.64％ in the control group (x2 =7.049,P ＜0.05).Conclusion For patients with tachyarrhythimia in the emergency department,the application of amiodarone has significant curative effects and high safety,which can help stabilize their blood pressure,heart rate and improve their conditions,and yet incurs less adverse reactions.Therefore,it is of significant value to be popularized in clinical applications.

Objective To examine whether IFN-λ has the ability to inhibit HIV-1 infection of blood monocyte-derived macrophages and its mechanism(s). Methods Macrophages were pretreated with IFN-λ/ IFN-λ2 for 24 h before infected by HIV-1 R5 strains (Bal, Jago, and JRFL). And then the culture supernatants were detected HIV-1 reverse transcription (RT) activity and p24 protein expression by HIV-1 BT assay and ELISA. The expressions of IFN-λ receptor, CD4, CCRS, CXCR4 were evaluated by real-time PCR. Results Both IFN-λ1 and IFN-λ2, when added to macrophage cultures, inhibited HIV-1 infection and replication. This IFN-λ-mediated anti-HIV-I activity is broad, as IFN-λ could inhibit infection by both laboratory-adapted and clinical strains of HIV-1. Investigations of mechanism(s) responsible for the IFN-λ action showed that although IFN-λ had little effect on HIV-1 entry receptor CD4 and co-receptor CCR5 and CXCR4 expression, IFN-λ inhibited HIV-I infection of macrophages through connecting with IFN-λ recep-tor. Conclusion IFN-λ could inhibit HIV-I replication in macrophages. These findings indicate that IFN-λ may have a therapeutic value in the treatment of HIV-1 infection.

Objective To analyze the relationships between body mass index (BMI), blood pressure and the cerebral vascular function in middle-aged population that underwent health checkup. Methods Participants from health management centers of Renmin Hospital of Hubei province, the Second Hospital Affiliated to Nanhua University, Hospital of Shandong Electric Power and Chinese People's Liberation Army No. 180 Hospital aged 45 to 64 years were selected from health checkup population by cluster sampling. Levels of height, weight and blood pressure as well as the cerebral hemodynamics were checked. Subjects were grouped according to age, BMI, systolic and diastolic blood pressure. The differences and distribution of cerebrovascular function scores (CVFS) between groups were compared and described. Moreover, the risk of stroke in the population was evaluated. Results Of the 17 258 individuals who met inclusion criteria, the abnormal rate (the score below 75 points) of CVFS was 20.9 percent. The CVFS in normal, overweight and obese groups were 91.0±15.4, 83.3±21.3, 70.3±26.5 and differences in all age groups were statistically significant (P<0.01). The CVFS in systolic blood pressure<120,120-139, 140-159,≥160 mmHg (1 mmHg=0.133 kPa) groups were 93.9±12.9, 86.5±18.9, 72.1±23.5, 56.2±25.7 and differences in all age groups were statistically significant (P<0.01). CVFS in normal diastolic pressure<80, 80-89, 90-99,≥100 mmHg groups were 91.0±16.1, 85.5±20.2, 75.4±23.6, 62.7±25.0 and the differences among all age groups were statistically significant (P<0.01). Conclusions The abnormal rate of cerebrovascular function integral and high risk stroke individuals in middle-aged health checkup people was approximately 21 percent. The overweight, obese and the high level of systolic and diastolic pressure may induce the injury of cerebrovascular function and the severity will increase with the level of BMI and blood pressure.

BACKGROUND:Studies have reported that the bone bridge and bone plug for meniscal alograft transplantation show better outcomes than simple soft tissue suture, but there are rare studies concerning the comparison of their fixation effects. OBJECTIVE:To compare the clinical effects of bone bridge and bone plug in meniscal alograft transplantation. METHODS:Eighteen patients undergoing arthroscopy-assisted meniscal alograft transplantation were enroled, including nine cases of bone plug fixation and nine cases of bone bridge fixation. Symptoms, physical examination, visual analog scale, Lysholm and Tegner scores were used to evaluate the clinic outcome. Every 6 months post operation, the signal and morphological changes of alograft meniscus was observed with MRI for each patient. RESULTS AND CONCLUSION:Al of the 18 patients were folowed up for 12-36 months after transplantation. No complications, absence of knee pain and effusion, and disappearance of the discomfort within the meniscectomy compartments after prolonged activity during folow-up period were found in al patients. The patients were competent of daily life and sports activity. The visual analog scale, Lysholm and Tegner scores were significantly increased after transplantation. MRI showed that the vicariousness and livability of the alograft menisci appeared within 1 year post operation. The safety and feasibility of the arthroscopy-assisted meniscal alograft transplantation were approved. Knee pain, knee effusion and joint stability and function were improved after arthroscopic-assisted alograft meniscus transplantation, and there was no difference between the clinical curative effects of the two kinds of fixed methods.
