ObjectiveTo determine the optimal combination of the effective monomer components "quercetin-kaempferol-abietic acid-boswellic acid" in Fujin Shengjisan for promoting diabetic ulcer （DU） wound healing through uniform design， thereby achieving the modern application of the ancient formula. MethodsFollowing the principle of "uniform design-pharmacodynamic experiment-mathematical modeling and model verification"， the U₁₄（14⁵） uniform design table was adopted.The four monomer components of Chinese medicine were considered as the independent variables， and the proliferation rate of human umbilical vein endothelial cells （HUVECs） induced by glucose was used as the pharmacodynamic indicator. A mathematical model was constructed using DPS software to correlate the effective monomer components with the pharmacodynamic indicator. The results of uniform design were verified through CCK-8 assay， cell scratch healing， tube formation， Western blot， and Real-time PCR. ResultsAmong the 14 compatibility groups， compared with the high-glucose model group， compound compatibility group 6 showed the strongest proliferation effect and statistical significance （P<0.05）. Four quadratic polynomial regression equations （Y₁-Y₄） were obtained through DPS modeling. Considering the model's fit， stability， and practical application， equations Y₁-Y₃ were selected for the follow-up verification. To ensure experiment reproducibility， group 6 was used for validation. Group 6 and equations Y₁-Y₃ were renamed as compound prescription ① to compound prescription④， respectively， to represent the modern application of the ancient FJSJ Powder through compatibility of monomer components. Verification experiments showed that in the CCK-8， scratch healing， and tube formation assays， the cell viability， wound healing rate， and tube formation number of HUVECs stimulated with 50 mmol·L^-1 glucose were significantly reduced compared with the blank group. Moreover， the expression levels of angiogenesis-related cytokines， vascular endothelial growth factor （VEGF） and fibroblast growth factor 2 （FGF2）， and CD31 secretion were significantly down-regulated. However， after intervention with compound prescriptions ① to ④， compound prescriptions ① and ③ significantly improved the biological functions of HUVECs induced by 50 mmol·L^-1 glucose. Further analysis of the regression coefficients of compound prescriptions ① and ③， and the relative dose ratios of each monomer component， indicated that abietic acid， quercetin， and boswellic acid promoted angiogenesis of HUVECs in the high glucose environment， with a major effect （positive partial correlation coefficients， all > 0.9）. Abietic acid and boswellic acid， as well as kaempferol and boswellic acid， promoted angiogenesis in HUVECs through interaction （positive partial correlation coefficients）. ConclusionCompound prescriptions ① and ③ are the optimal combinations. They can reverse the inhibitory effects of high glucose， stimulate the proliferation， migration， and tube formation abilities of HUVECs in a high glucose environment， and promote the expression of vascular endothelial growth factorA（VEGFA）， FGF2， and CD31， thereby promoting angiogenesis and facilitating DU wound healing. This finding not only confirms the good reproducibility and feasibility of compound prescriptions ① and ③ but also provides new insights and methods for the rational construction of mathematical models to further study the compatibility theory of Chinese medicine.

Epilepsy is a chronic brain disease characterized by seizures， and is one of the most common nervous system diseases in clinic practice with the recurrent， transient， and refractory characteristics. Clinically， western medicine therapy is mainly adopted in the treatment of epilepsy， but it is not conducive to long-term use for patients on account of severe side effects， which can result in abnormalities in the digestive system， central nervous system， hematopoietic system， urinary system， and liver function to varying degrees. Syndrome differentiation is usually used for the treatment of epilepsy by traditional Chinese medicine （TCM）， which can avoid the side effects of western medicine treatment on the basis of improving patients' syndromes. The literature on TCM in the treatment of epilepsy in China and abroad indicates that the syndrome differentiation in TCM is often based on phlegm， blood stasis， wind， and deficiency， and the treatment methods include acupuncture， acupoint catgut embedding， moxibustion， Chinese medicine monomer， drug pair， and compound decoction. The various treatments of TCM play an important role in the comprehensive treatment of epilepsy through multiple channels and links， such as reducing the degree and number of seizures. This paper comprehensively summarized the clinical experience of TCM in the treatment of epilepsy， systematically expounded various treatment methods and ideas of TCM in the treatment of epilepsy， and deeply discussed the mechanism of TCM in the treatment of epilepsy， aiming to provide a theoretical basis for the clinical formulation of a reasonable individualized treatment plan for epilepsy and diversified ideas for the more effective treatment of epilepsy by TCM.

Objectives: This study explored the relationship between weight control and atrial fibrillation (AF) recurrence after catheter ablation in overweight and obese patients. Methods: We prospectively enrolled consecutive 333 overweight and obese patients aged 28 to 87 years old, who underwent catheter ablation for AF in Beijing Anzhen Hospital between October 2015 and February 2016. Data of patients′ characteristics, laboratory examination and treatment were collected at baseline. Each patient was followed up at 3, 6 and 12 months after ablation to collect information on weight, AF recurrence, stroke, major bleeding, hospitalization for cardiovascular reasons and death, etc. Patients were divided into weight controlled group (ΔBMI<-1 kg/m²) and weight uncontrolled group (ΔBMI≥-1 kg/m²), according to the changes in the most recent exposure BMI before AF recurrence in patients with recurrence or the BMI at 12 months′ follow-up in patients without recurrence and the BMI at baseline. Multivariate logistic regression was performed to adjust other known risk factors of AF recurrence and to explore the association between weight control and AF recurrence after catheter ablation. Results: There were 54 patients in weight controlled group and 279 patients in weight uncontrolled group. There were no significant differences in age, gender, education level, left atrial size and history of hypertension between the two groups (all P>0.05). The proportion of patients using angiotensin-converting enzyme inhibitors/angiotensin receptor blockers was higher in the weight controlled group (50.0%(27/54) vs. 34.8%(97/279), P=0.034). However, there was no significant difference in the proportion of patients with obesity (33.3% (18/54) vs. 29.7% (83/279)), paroxysmal AF (59.3% (32/54) vs. 56.6% (158/279)) and AF duration less than 5 years (76.9% (40/52) vs. 65.4% (178/272)) between the weight controlled group and the uncontrolled group. During 1-year follow-up after ablation, the recurrence rate of AF was significantly lower in the weight controlled group than that in the weight uncontrolled group (14.8% (8/54) vs. 32.6%(91/279), P=0.009). Multivariable logistic regression analysis shows that weight control is independently associated with a lower postoperative AF recurrence rate (OR=0.40, 95%CI 0.18-0.90, P=0.026). Conclusion Weight control is strongly associated with a lower AF recurrence rate after catheter ablation in overweight and obese patients.

Objective: To understand the prevalence of infectious diseases in schools in Beijing in 2010-2017 academic years, and to provide the reference for the prevention and control of infectious diseases in schools. Methods: Based in Disease Surveillance Information System, students aged 6-22 years were selected in 2010-2017 academic year into this descriptive analysis, and the legal infectious diseases and the intensively monitored diseases of surveillance system in Beijing were included. Results: From 2010 to 2017 academic years, the incidence rate of notifiable and certain monitored infectious diseases declined from 1 213.48/100 000 to 749.30/100 000, the incidence rate of notifiable infectious diseases declined from 718.19/100 000 to 523.50/100 000. There was no report of category A. The top 4 infectious diseases of category B were scarlet fever(80.13/100 000), bacillary dysentery(74.42/100 000), tuberculosis(22.70/100 000) and acquired immunodeficiency syndrome (AIDS)(4.03/100 000). The top 4 diseases of category C were other infectious diarrhea(157.62/100 000), hand foot and mouth disease(100.55/100 000), influenza(51.39/100 000)and mumps(49.47/100 000). The other particular monitored infectious disease was mainly chicken pox(296.04/100 000). The prevalence of AIDS and influenza increased significantly in recent years. The main infectious diseases in primary and junior school students were scarlet fever, hand foot and mouth disease, influenza, and in high school and college students were AID, tuberculosis and viral hepatitis. Conclusion In the 2010-2017 academic year , the number and incidence of notifiable infectious diseases and particular monitored infectious diseases among students in Beijing showed an overall downward trend. The main diseases among students in Beijing are scarlet fever, bacillary dysentery, infectious diarrhea and chicken pox. Prevention and control of AIDS, tuberculosis and viral hepatitis in high school and college students should be paid special attention.

Objective: To understand the changes of smoking behavior among primary and middle school students in Beijing during 2005-2015. Methods: The primary and middle schools in Beijing were classified and then taken as a sampling frame. Twophase stratified random cluster sampling was conducted with school as primary sampling unit (PSU) and class as the minimum sampling unit, respectively. Beijing Schoolbased Smoking Monitoring Questionnaire was surveyed in 2005 and 2005, 2010, 2011, 2013 and 2015 anonymously. Results: In 2015, the smoking rate among primary and middle school students in Beijing was 9.41%. Among them, for primary, junior, high school and vocational high school students, the rates were 7.05%, 7.06%, 12.41% and 34.11%, respectively. The smoking rates were now 3.26%, with 1.99%, 1.80%, 3.48% and 20.22%, respectively, among primary, middle and high school and vocational high school students. male, vocational school students were more likely to report smoking across six waves of surveillance. Results from the surveillance in 2015 showed a decreasing trend in ever smoking rate and current smoking rate compared with previous survey. About half of the current student smokers were reported to take 1 cigarette/day, and about 10% smokers were reported to take 10 cigarettes/day. Students were most likely to smoke at home(24.02%), followed by smoking at schools(12.74%). The percentage of buying cigarettes by themselves was increased from 17.10% in 2008 to 66.09% in 2015. Conclusion From 2005 to 2015, both ever smoking and current smoking rate among middle school students in Beijing decreased in general, however smoking among vocational high school students warrants further attention.

Objective To investigate the prevalence and influencing factors associated with frailty among institutional older adults and to provide evidence for intervention study.Methods A total of 237 older adults living in four welfare homes from Chengdu in Sichuan Province were recruited by convenience sampling.A cross-sectional survey was conducted,and frailty was assessed by the frailty phenotype;general information was collected by selfmade general information questionnaire;functional capacity was assessed by Barthel questionnaire;depressive status was assessed by GDS-15;cognitive function was assessed by clock drawing test and nutritional status was assessed by short form mini nutritional scale questionnaire (MNA-SF).Results The reported rate of frailty was 55.69％ among institutional older adults,and 44.31％ reported no frailty;grip weakness (207,87.3％),slow walking speed (172,72.6％) and low physical activity(131,55.3％) were the main frailty problems.Univariate analysis showed that the elderly'frailty conditions were different in the pre-retirement occupations,smoking,alcohol consumption,physical exercise,chronic diseases,medication,acute events (last year),self-reported health,using assisted walking devices,ability of daily life,depression,cognitive ability and nutritional status,and the differences were statistically significant(P＜0.05).Conclusion The status of frailty is not optimistic among institutional older adults and many factors are associated with frailty.Healthcare providers should pay more attention to the frailty issue and take timely intervention strategies to prevent or delay the frailty.

Objective To explore the effects of acupoint application of midnight-noon ebb-flow with hour-prescription of points on dysfunction for sufferers with senile osteoporosis(SOP).Methods In this study,76 patients with SOP in clinic in this hospital were recruited and randomly divided into the experimental group(n=38) and the control group(n=38) in accordance with random number table.Both were on the basic treatment of Caltrate D.The experimental group performed acupoint application of midnight-noon ebb flow with hour-prescription of points,while the control one performed common acupoint application.Oswestry Disability Index(ODI) was used to evaluate the dysfunction before,after 4 weeks and 8 weeks of intervention.SF-36 was adopted to evaluate the patients' quality of life before and after 8 week's intervention.Results The ODI scores of the experimental group after 4 weeks and 8 weeks were lower than those of the control group(P＜0.01).Repeated ANOVA indicated that the scores of ODI in group effect,time effect and interaction effect were of statistical significance(P＜0.01).Further comparison showed that the scores of ODI in three different time sections suggested that the latter time point were lower than those of the former time point(P＜0.01).The scores of eight dimensions of SF-36 after the intervention of the experimental group were higher than those of the control group(P＜0.05).Conclusion The acupoint application of midnight noon ebb flow-with hour-prescription of points can effectively improve the dysfunction whose curative effect enhanced with time increasing and improve the quality of life.

OBJECTIVETo compare the clinical efficacy differences between acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method and traditional acupoint plaster therapy for senile osteoporosis (SOP).

METHODSWith randomized controlled blind design, 76 SOP patients with deficiency of liver and kidney syndrome were randomly divided into an observation group and a control group, 38 cases in each one. Based on oral administration of caltrate D, the patients in the observation group were treated with acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method at Yingu (KI 10), Taixi (KI 3), Dazhong (KI 4), Fuliu (KI 7) and Zhiyin (BL 67), while the patients in the control group were treated with traditional acupoint plaster therapy. Each plaster therapy lasted for 6 h, once a day; there was an interval of 2 d after consecutive 5-day treatment; 4 weeks were taken as one course, and totally 2 courses were given. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate the pain and dysfunction before intervention, after 4 weeks and 8 weeks intervention. Osteoporosis symptom rating sale and quality of life questionnaire of the European foundation for Osteoporosis (QUALEFFO-41) were adopted to evaluate the TCM syndrome and quality of life before and after 8-week intervention.

RESULTSAll the outcomes were significantly improved after treatment in the two groups (<0.01,<0.05); after 4 weeks and 8 weeks of treatment, the VAS and ODI in the observation group were lower than those in the control group (all<0.05). Repeated ANOVA indicated the VAS and ODI were significant in group effect, time effect and interaction effect (all<0.01). Further comparison showed that VAS and ODI at later time points were lower than those in the early time points (all<0.01). After the treatment, the scores of TCM syndrome and QUALEFFO-41 in the observation group were lower than those in the control group (all<0.05). The effective rate was 85.7% (30/35) in the observation group, which was superior to the effective rate in the control group[74.3%(26/35),<0.05].

CONCLUSIONSThe acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method is superior to traditional acupoint plaster therapy in improving pain, dysfunction, TCM syndrome and quality of life in SOP patients; in addition, its clinical efficacy is significant.

Objective Cryoballoon ablation of pulmonary vein (PV) ostia often induces a vagal response.This prospective study was designed to assess the effectiveness of prophylactic intravenous administration of atropine on hemodynamic impairment induced by cryoballoon ablation in patients with atrial fibrillation.Methods Twenty-five patients with paroxysmal atrial fibrillation undergoing cryoballoon ablation were prospectively enrolled and assigned to either the trial group on the control group.First twelve patients (the trial group) were administered 1 mg of atropine before deflation of the cryoballoon,while the following 13 patients (the control group) were given atropine only after the onset of the hemodynamic variation (decrease in heart rate and/or blood pressure).Treatment was considered effective when the hemodynamic variations were restored.Results In the trial group,three patients with transient hypotension did not require further supportive care throughout the procedures and one patient with hypotension required supportive management.In the control group,hypotension,bradycardia and mixed bradycardia with hypotension requiring supportive care occurred in six,three,and three patients,respectively.Overall,the rate of marked vagal responses was significantly lower when prophylactic atropine was administrated (4/12 vs.12/13 patients,P ＜ 0.01).Conclusions Atropine is effective in the prevention of all types of vasovagal responses induced by cryoballoon ablation in patients with atrial fibrillation.
