On the basis of Poincare scatter plot and first order difference scatter plot, a novel heart rate variability (HRV) analysis method based on scatter plots of RR intervals and first order difference of RR intervals (namely, RdR) was proposed. The abscissa of the RdR scatter plot, the x-axis, is RR intervals and the ordinate, y-axis, is the difference between successive RR intervals. The RdR scatter plot includes the information of RR intervals and the difference between successive RR intervals, which captures more HRV information. By RdR scatter plot analysis of some records of MIT-BIH arrhythmias database, we found that the scatter plot of uncoupled premature ventricular contraction (PVC), coupled ventricular bigeminy and ventricular trigeminy PVC had specific graphic characteristics. The RdR scatter plot method has higher detecting performance than the Poincare scatter plot method, and simpler and more intuitive than the first order difference method.
Objective To explore the hemodynamic assessment after radical surgery in children with tetralogy of Fallot (TOF) by both echocardiography and Mostcare monitor. Methods Clinical data of 63 children with TOF who underwent radical surgery in our hospital from February 2016 to June 2018 were retrospectively analyzed, including 34 males and 29 females, aged 6-24 (9.82±5.77) months. There were 19 patients undergoing transannular patch reconstruction of the right ventricular outflow tract (a transannular patch group) while 44 patients retained the pulmonary valve annulus (a non-transannular patch group) . The echocardiography and Mostcare monitor parameters were recorded and brain natriuretic peptide was tested at the time points of 0, 8, 12, 24 and 48 hours after operation (T 0, T 1, T 2, T 4) to analyze their correlations and the change trend at different time points after radical surgery. Results The left ventricular ejection fraction at T 1 (43.49%±3.82%) was lower than that at T 0 (48.29%±4.55%), T 2 (45.83%±3.69%), T 3 (53.76%±4.43%) and T 4 (60.54%±3.23%, P<0.05). The cardiac index at T 1 (1.85±0.35 L·min−1·m−2) was lower than that at T 0 (2.11±0.38 L·min−1·m−2), T 2 (2.07±0.36 L·min−1·m−2), T 3 (2.42±0.37 L·min−1·m−2) and T 4 (2.82±0.42 L·min−1·m−2, P<0.05). The cardiac circulation efficiency at T1 (0.19±0.05) was lower than that at T 0 (0.22±0.06), T 2 (0.22±0.05), T 3 (0.28±0.06) and T 4 (0.34±0.06, P<0.05). The right ventricular two-chambers view fraction area change at T 1 (23.17%±3.11%) was lower than that at T 0 (25.81%±3.74%), T 2 (25.38%±3.43%), T 3 (30.60%±4.50%) and T 4 (36.94%±5.85%, P<0.05). The pulse pressure variability was the highest at T 0 (18.76%±3.58%), followed by T 1 (14.81%±3.32%), T 2 (12.44%±2.94%), T 3 (10.39%±2.96%) and T 4 (9.18%±1.92%, P<0.05). The blood brain natriuretic peptide was higher at T 1 (846.67±362.95 pg/ml) than that at T 0 (42.60±18.06 pg/ml), T 2 (730.95±351.09 pg/ml), T 3 (510.98±290.39 pg/ml) and T 4 (364.41±243.56 pg/ml, P<0.05). There was no significant difference in left ventricular ejection fraction, cardiac circulation efficiency and heart index between the two groups (P>0.05). The right ventricular two-chambers view fraction area change of the transannular patch group was significantly lower than that of the non-transannular patch group at each time point (P<0.05). The blood brain natriuretic peptide and pulse pressure variability of the transannular patch group were significantly higher than those of the non-transannular patch group (P<0.05). Left ventricular ejection fraction was positively correlated with cardiac index (r=0.637, P=0.001) and cardiac circulation efficiency (r=0.462, P=0.001) while was significantly negatively correlated with blood brain natriuretic peptide (r=–0.419, P=0.001). Conclusion Both methods can accurately reflect the state of cardiac function. Mostcare monitor has a good consistency with echocardiography. Using transannular patch to recontribute right ventricular outflow tract in operation has more influence on right ventricular systolic function. The Mostcare monitor can guide the hemodynamic management after surgery in real time, continuously and accurately.
Objective To be aware of the treatment status and economic burden of people with hemophilia (PWH) in mainland China, so as to seek the optimal therapy for them. Methods The relevant Chinese and English databases such as CBM, CNKI, VIP, WanFang Database, PubMed, EMbase and The Cochrane Library (Issue 6 of 12, June 2011) were searched in June, 2011. The economic analyses and studies on PWH treatment and economic burden published from 1980 to 2011 were collected. Results The diagnosis and treatment of PWH in mainland China lagged behind. More than 30% of PWH did not receive or occasionally received treatment, and less than 10% received prophylactic therapy. Lots of PWHs still used FFP or cryoglobulin which were easily to cause blood-borne viral diseases. More than half of PWH families could afford a little or completely could not afford the therapy. Low dose prophylactic therapy was cost-efficient than on-demand therapy. Based on the therapy status, it was estimated that approximately RMB 53 844 yuan per year per patient should be put into practice in order to have PWH received low-dose prophylactic therapy, and to prevent 80% of bleeding. Conclusion PWH in mainland China is poor in treatment status and heavy in economic burden, so it is an optimal way to adopt comprehensive care model and low-dose prophylactic therapy in mainland China.

Objective To explore the impact of community healthcare workers’ (CHWs) knowledge, attitude and practice (KAP) on the influenza vaccination among elderly people. Methods By means of simple random sampling, 1 residential quarter of each communities, 2 communities of each districts, 5 districts of Chengdu city were randomly selected, and the elderly equal to or more than 60-year-old were on-site investigated. Meanwhile, the questionnaire survey was conducted among healthcare workers in the selected communities. Results There were 4 KAP factors played a positive role in influenza vaccination among elderly people: CHWs’ affirmation of the effectiveness of influenza vaccine, explicitly knowing the focus groups for influenza vaccination, recommendation of vaccination in flu season when the elderly visits, and participation in flu-related education activities. When the accuracy rate of each factor got improved by 1%, the influenza vaccination rate would improve by 2.747%, 1.299%, 0.864%, 0.602%, respectively. Conclusion The knowledge, attitude and practice of HCWs have impacts on the influenza vaccination rates of elderly people. They are significant to improve the influenza vaccination rates of the elderly.
Objective To understand the current situation of medical service and management in Luxi township health center (LxC) in Yongxin county of Jiangxi province, so as to provide baseline data about drug allocation, logistic key techniques research and products development for township health centers. Methods By means of questionnaire and focus interview, the LxC was investigated from the following aspects: general information, human resources, medicine list, basic device configuration, medical service and management, as well as service efficiency. Results a) Yongxin county including 13 village committees covers an area of 86 km2, with the population of 22 300 in 2009, and it pertains to a backward area with the annual per capita income of RMB 4 100 yuan; b) Among the total 28 staffs in LxC, 78.6% were health workers; the general practitioner (GP)/nurse ratio was about 1?0.58; the proportion of GP, nurses, medical technicians, other staffs was 54.55%, 31.82%, 9.09% and 4.54%, respectively; the proportion of bachelor degree, junior college graduation and secondary technical school graduation was 9.1%, 13.6%, and 77.3%, respectively; and the ratio of elementary, middle, and high professional title of health workers was 15?5?1; c) There were 625 species of drugs in LxC in 2009, and the hospital beds approved by government were 0.69 per thousand agricultural persons, which, however, were 1.15 in fact. The rate of 51 basic equipments shown in national regulation was actually 76.5%, and the readiness and utilization rate of existing 40 equipments was 92.5%; and d) In 2009, the outpatients were 12 150 person-time, with the average cost of RMB 29.39 yuan; the hospital discharge was 1 589 person-time, with the average stay of 12 days and the average cost of RMB 490.05 yuan; the vaccine inoculations were 5 053 person-time; among the total income, the medical service income accounted for 73.2%, while the drug income accounted for 53.7%; the personnel expenditure was 31.0% of the total, and the balance of income and expenditure was RMB –263 500 yuan. Conclusion The hardware condition of LxC is not so good owing to the financial difficulties of Yongxin county and Jiangxi provincial government. In comparison with the whole country, although the professional title structure is ok, health workers are still not enough, with unreasonable specialty structure and low educational background. The rate of basic equipments and the approved hospital beds per thousand agricultural persons are low. There are 625 species of drugs, containing 218 species shown in 2009 national essential medicine list. And the other conditions are as follows: no information system, lack of public health service, short of financial input, high ratio of “running hospital by selling drugs”, and low efficiency of medical service. So the top priority of LxC construction should be figuring out all of the above issues, and better serving the people.
Objective To investigate current situation of medical service and management in Gaozha Central Township Health Center (GzC), so as to provide baseline data for township health centers in both key techniques research and product development of drugs allocation and delivery. Methods A questionnaire combined with a special interview was carried out, which included the general information, human resources, medical service and management, and the practice of essential medicine list. Results a) The hardware condition of GzC was not good enough, and the economic status of the service recipients was lower than the average level of both Wuzhong City and China mainland; b) The constituent ratio of general practitioner (GP) and nurse, and GP and laboratorian were all lower than those of national level, while, the constituent ratio of GP and technician was a little bit higher. GzC was in short of medical technical personnel and, especially, the professional pharmacists. The logistics technical workers were as the same proportion as the nurses. The medical technical personnel without professional education background accounted for 3.4%, and about 38% of the staff members had no college degree, about 86.2% had at most primary profession titles. There was no personnel turnover of GzC in recently years; c) The bed utilization ratio was lower than national level (46.4% vs. 60.7%), while the average duration of stay and the in-patient and out-patient service workload of GP were longer or heavier than national level (8 vs. 4.8, 9 vs. 8.3, 4 vs. 1.3); d) The out-patient service in 2010 decreased 26.9% compared to 2009; and the in-patient service in 2010 decreased 42.4%; e) The average medical expense per outpatient and per inpatient increased 127.3% and 56.2%, respectively in 2010 compared to 2009; and f) Essential medicine list was put into practice in April 1st of 2010 and there was only 195 species available in GzC, which has not met the requirements of the national essential medicine list. Conclusion In order to meet the standards of general rural township health center in western China, GzC needs to cope with challenges of insufficient hardware conditions, short of staff, unreasonable personnel structure, low educational background and professional title of the staff, none human resources flow and low technical level of medical service. GzC dose well in drug expenses control, and the hospitalization costs are lower than those of the national level. However, it increases rapidly in 2010. The management of GzC may be influenced by zero-profit sale of the essential drugs, and appropriate subsidy and policy support are necessary to maintain its service quality. And it is required to complement the medicine based on the evidences, to carry out staff training and usage guidance of essential medicine, and to finally guarantee the safe and reasonable use of medicines.
Objective To understand current situation of medical service and management in Yong’an Central Township Health Center (YaC) through on-the-spot investigation, in order to provide references for personal employment and essential medicines list implement in township health centers. Methods Questionnaire and focus interview were carried out, which included the general information, human resources, medical service and management, and the practice of essential medicines list. Results The hardware equipments of YaC were fine, and the target population had fairly good health and economy status. The ratio of General Practitioner (GP)/ nurse and GP/ pharmacist were all above the national average level. The members with college degree and above accounted for 61.6%, and about 88% staffs were with or below primary profession titles. There was a balance between personnel flow out and in. The drug income accounted for 53.6% of the whole in 2009 and the medical expenses increased compared to 2008. Essential medicines list was put into practice in April 1st of 2010 with no relevant technical documents as correspondence. Conclusion YaC, as a good representative of fairly well-off rural Township Health Center in western China, needs to cope with challenges of irrational personnel structure, low educational background and professional title of the staff and human resources flow, and requires developing policy and adopting measures step by step. The management of YaC may be influenced by zero-profit price of the essential medicine, and appropriate subsidy and policy support are necessary to maintain current service quality.
Objective To seek evidence based methods to treat bedsore of aged patients. Methods We raised clinical questions according to the condition of an eighty-year old male patient, and then, with "bedsore" (treatment or prevention) as key words we searched evidences from Cochrane Library (2nd edition 2002), Medline (1996-2002.4), and Sumsearch. Results We found 3 SR (systematic review) from Cochrane Library, 3 Meta-analyse and 38 RCT (randomized controlled trial) from medline, and 3 SR and 9 RCT from Sumsearch. Conclusion 1 Various types of mattress are useful in prevention the bedsore. 2 There is still not enough evidences of electromagnetic therapy. 3 In state II bedsore, healing is faster in using collagen Dressing than using water-glue Dressing. 4 Local application of antibiotics and Phenytoin sodium can accelerate the growth of new granulation tissue. 5 Nutritional support is necessary for bedsore prevention and healing. According to these evidence, we make the best care plan for this patient. After our treatment, the wound healed 10 days later, and he doesn’t occur bedsore any more.
