Objective: To analyze the prevalence and risk factor of co-exiting pre-hypertension and pre-diabetes condition in middle to elder adults, and to provide the theoretical basis for preventing cardiovascular disease in relevant population in Chengdu area.
Methods: A total of 5240 middle to elder adults from (40-79) years of age in Chengdu area were enrolled for a stratiifed cluster sampling study. The blood pressure, glucose and other clinical information were collected by more than 30 medical professionals with uniifed training to investigate the prevalence of co-exiting pre-hypertension and pre-diabetes condition with the risk factors.
Results: The overall prevalence rate of coexisting pre-hypertension and pre-diabetes condition was at 12.5% in Chengdu area and the standardized prevalence was at 11.5%. The prevalence rate in urban area was 12.4% and in rural was 13.2%, P=0.47, the prevalence in male gender was 12.7% and in female was 12.4%,P=0.81. With the increased age, the prevalence trend was elevated accordingly. Multi-regression analysis indicated that the elder age, overweight or obesity (female with abdominal obesity), sibling history of hypertension, hyper-triglyceridemia, multiple childbirth and menopause had the higher risk of coexisting pre-hypertension and pre-diabetes condition, allP<0.05; the higher educational level could decrease the risk of prevalence in male gender,P<0.05 and the proper exercise could decrease the risk in female gender,P<0.05.
Conclusion: There is a high prevalence rate of coexisting pre-hypertension and pre-diabetes condition in middle to elder population in Chengdu area and the prevalence is closely related to age. It is important to prevent such condition by elevating educational level nationwide, controlling waist and body weight, adjusting diet structure with proper exercise.

For optimal adaptive cultivation region selection, we used ecology factors characterized Duolun region as model area to carry out the adaptive habitat division of Paeonia lactiflora. Similar priority comparison of ecology factors.in 91 cities were calculated by Fuzzy methods, then, distance of the ecology factors were transferred to spacial model by geography information system (,GIS) and modified by soil utilization map of China. The results showed that P. lactiflora were mainly distributed in the Daxing'an Mountain, Changbaishan and qinling range which were divided into six grades of suitable regions belonging to three geographical distributed units. The most similar areas to Duolun were Huade, Xilinhaote, Suolun and Zhangbei. P. lactiflora's distribution and quality are relevant with longitude and latitude, and temperature and rainfall.

Objective:To explore the predictive value of Red Blood Cell Distribution Width (RDW) in predicting the prognosis of patients with Extracorporeal Membrane Oxygenation (ECMO).Methods:The clinical data of patients undergoing ECMO admitted to Intensive Care Unit of Sichuan Provincial People’s Hospital from January 2015 to January 2020 were retrospectively analyzed. Patients were divided into the survival group and death group according to the prognosis during ICU hospitalization. The patients' basic data , acute physiology and chronic health score system Ⅱ (APACHE Ⅱ), RDW and activated partial thromboplastin time (APTT) at 72 hours after treatment with ECMO were compared between the two groups. Univariate and Logistic regression multivariate analyses were used to analyze the prognostic factors of patients with ECMO, predictive models and death warning scores were established. The receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficacy of RDW and death warning scores for the prognosis of patients with ECMO.Results:A total of 71 patients with ECMO who met the inclusion criteria were included, including 38 patients in the death group and 33 patients in the survival group. The age, APACHE-Ⅱscore, 72 h RDW and 72 h APTT in the death group were higher than those in the survival group. Respectively, the hospitalization time of ICU in the death group was significantly lower than that in the survival group ( P< 0.05). Logistic regression analysis showed that APACHE-Ⅱscore ( OR=1.117, P=0.047)、72 h RDW( OR=1.102, P=0.029) and 72 h APTT ( OR=1.049, P=0.029) were independent risk factors for death in patients with ECMO. ROC curve analysis showed that the area under ROC curve (AUC) of the APACHE-Ⅱ, score 、72 h RDW and 72 h APTT were 0.691, 0.691 and 0.632( P<0.05), Respectively, the combined AUC was 0.764, the sensitivity was 0.526, and the specificity was 0.909. The death warning score of patients with ECMO was established according to the Predictive model , which is less than 2 points with low risk of death and more than 2 points with high risk of death. The area under the ROC curve of death warning score is 0.8, the sensitivity is 0.607 and the specificity is 0.923. Conclusions:The RDW at 72 hours after treatment with ECMO has a good value in predicting the prognosis of patients with ECMO. Besides, a greater predictive value for the prognosis of patients with ECMO by combining 72 hours RDW, 72 hours APTT with APACHE-Ⅱscore than that of any separate indicator.

Objective:To observe the effect of NGF on the expression of BMP-2 in rabbit model and explore the molecular mechanism of NGF which might promote the healing of mandibular fracture with nerve injury. Method:The 48 New-Zealand white rabbits were randomly divided into the experimental group (mandibular fracture+to cut off the nerve bundle+NGF by GS), the control group (mandibular fracture+to cut off the nerve bundle+NS by GS), the blank group (mandibular fracture+to cut off the nerve bundle) and the full-set group (mandibular fracture+retains the nerve bundle). After 2 weeks, 4 weeks, 6 weeks and 8 weeks, 3 rabbits were sacrificed in each group for HE staining and RT-PCR, respectively. Result:HE staining showed the osteogenesis phenomenon: the experimental group was clearer than control group, the full-set group was clearer than the blank group and the control group is similarly to the blank group. RT-PCR results revealed that there was a statistically significance in the early stage. The expression of BMP-2 peaked in 2 weeks and decreased later with time. Conclusion:The local application of NGF can prompt BMP-2 expression in the early stages of the mandibular fracture with partial nerve injury healing and this may be one of the molecular mechanisms.

Objective:To introduce how to quickly set up a doctor team to achieve efficient treatment of batchs COVID-19 patients in Changchun GongTi shelter hospital.Methods:A cross-sectional study was conducted to analyze the basic situation of the doctors who supported the Changchun Gongti shelter hospital. The workload is the total number of patients from April 3 to 28, 2022. At the beginning of the task, the first week and the third week of the task, the five point scoring method was used to reflect the doctor's physical and mental state, stress state and rescue achievement. The time phased scheduling and disease grading management were fully implemented after 10 days of operation in the shelter. The doctors' ward round efficiency and self scoring changes before and after the implementation of the plan were compared, and the rescue results were summarized.Results:Total of 56 doctors (the Sichuan medical assistance team to Changchun), who undertook the work of Changchun Gongti shelter Hospital, came from 12 professional departments of 14 hospitals. By internal and external linkage-time phased scheduling and information-based patient zoning and grading management, the admission time of batch patients was shortened from (14.64±10.09) min to (6.80±5.10) min per person( P<0.05), the number of patients that each doctor can view per hour ranges from (28.50±12.26) to (68.43±19.95) ( P<0.01). A total of 1 293 patients were treated. There were no deaths, no accidents and no mild illness to severe illness in shelter hospital. 35 doctors completed a continuous survey. Before and after the implementation of those measures, the average physical state scores and the psychological state scores of doctors improved ( P=0.03), the self-score of stress feeling decreased ( P<0.01), and the self-score of professional achievement increased ( P<0.01). Conclusions:To adapt to the characteristics of emergency treatment for batch COVID-19 patients, the internal and external linkage-time phased scheduling and information-based patient zoning and grading management could help the temporarily convened doctors deal with a large number of patients efficiently, reduce work stress and exposure risk in shelter hospital.
