Objective To understand the production condition of Chinese medicinal materials in Dingxi City during 2004-2014 from the aspects of planting area, yield of per unit area and total product; To provide technical guidance for future research on Chinese medicinal materials in Dingxi City. Methods Statistics like planting area, yield of per unit area and total product in counties (districts) collected by Dingxi Municipal Statistics Department were adopted for analysis. Results During 2004-2014, planting area of Chinese medicinal materials in Dingxi City reflected an upward trend, and Minxian County had the largest planting area, followed by Longxi County, Weiyuan County. Lintiao County showed the most obvious increase in planting area, followed by Zhang County. Planting area in Anding County and Tongwei County reflected a downward trend. Minxian County has the highest average per unit area yield of Chinese medicinal materials, as the 3.10 t/hm2. Total product of Chinese medicinal materials in Dingxi City showed great changes, and decreased in Anding County. Conclusion Conclusion During 2004-2014, the planting area, yield of per unit area and total product of Chinese medicinal materials showed an upward trend in general and differences in different counties (districts).

Objective To investigate the effectiveness and safety of combined heparin and acutobin in the treatment of acute inferior vena cava thrombus in rabbits. Methods The inferior vena cava thrombus model was established in 72 rabbits and they were randomly divided into three groups; heparin group(A) , group for combination of urokinase and heparin (B), group for combination of acutobin and heparin (C) ,each group including 24 rabbits. Drugs were administrated 3 days after thrombosis. Coagulation indexes were tested to assess their safety, and Doppler ultrasound was used to assess their effectiveness, on day 3, day 7, and day 10. Results The prolongation of prothrombin time ( PT) in group C was shorter than that in group B( P < 0. 05 ) , the fibrinogen ( FBG) value in group C was lower than that in group B (P < 0. 05 ) , the prolongation of PT in group B and group C was longer than that in group A (P < 0. 01), the FBG value of group B and C were higher than that in group A ( P < 0. 01 ), D-dimer ( D-D) value in group B and C gradually returned to normal range. There was no difference between the two groups (P > 0. 05). The thrombolytic effect in group B and C were better than that in group A, statistical difference was reached between groups B and A (P <0. 01), and the difference was statistically significant between groups C and A 10 days after administration (P < 0. 01). Thrombolytic effect was not different statistically between groups B and C (P > 0. 05). Conclusion Acutobin combined with heparin in the treatment of acute inferior vena cava thrombus in rabbits was effective and safe.

Objective By learning about the current basic situation of research on national scientific and technological achievements of three species of Chinese herbal, Radix Angelicas, Radix Astragall and Radix Codonopsis, to reveal the features in literature and research content, and provide reference for related research in future. Methods By using content analysis approach, the basic situation of achievements, the research content of achievements, and assessment and application of achievements were classified and statistically analyzed by classifying and statistical function of computer. Results The provinces that rank the top of national scientific and technological achievements of the three species of Chinese herbal were Gansu, Hebei and Shandong. The achievements were mainly undertaken by college or university, hospital and scientific research institutions. The source of project achievements mainly originated from local project and optional project. The research content of the achievements largely focused on the fields like drug therapeutic effect, pharmaceutical preparation, cultivation techniques, storing and processing. Conclusion In the database (HowNet) of national scientific and technological achievements, the amplification of national scientific and technological achievements of the three species of Chinese herbal is slow, the achievements mainly focus on application technology, the conversion rate of achievements is low, and large amount of data of achievement items in database is missing.

Objective:To investigate the epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with maintenance hemodialysis (MHD) in Jiangsu province during SARS-CoV-2 pandemic in China from December 7, 2022 to January 27, 2023, and to analyze the influencing factors of all-cause death.Methods:It was a multi-center cross-sectional investigation. Structured questionnaire was used to collect patient information by medical staff of each hemodialysis center (room) as investigators. Part of the demography data and laboratory examination data came from the Jiangsu Province Hemodialysis Data Information System. MHD patients from hemodialysis centers (rooms) at all levels of medical institutions and independent hemodialysis institutions in Jiangsu province during the outbreak of SARS-CoV-2 infection were included, and the clinical characteristics and all-cause mortality of confirmed and suspected cases of SARS-CoV-2 infection were analyzed.Results:Questionnaire surveys and data analysis on 57 278 patients in 407 hemodialysis centers (rooms) were completed, accounting for 90.41% of the total number of MHD patients (63 357 cases) in Jiangsu province during the same period. There were 24 038 cases (41.97%) of SARS-CoV-2 infection and 14 805 cases (25.85%) of suspected infection, which were widely distributed in all dialysis centers in Jiangsu province. After clinical classification of 38 843 confirmed and suspected SARS-CoV-2 infection cases, 3 662 cases were severe and critical cases, accounting for 9.43% of the infected and suspected cases. Among the patients who had completed the questionnaires, there were 1 812 all-cause deaths, with an all-cause mortality rate of 3.16%. Multivariate logistic regression analysis showed that elderly (taking ≤50 years as a reference, 51-59 years: OR=1.583, 95% CI 1.279-1.933, P=0.001; 60-69 years: OR=3.972, 95% CI 3.271-4.858, P<0.001; 70-79 years: OR=7.236, 95% CI 5.917-8.698, P<0.001; ≥80 years: OR=11.738, 95% CI 9.459-14.663, P<0.001), male ( OR=1.371, 95% CI 1.229-1.529, P<0.001), and co-infection with hepatitis B virus (HBV) (positive serum HBV surface antigen, OR=0.629, 95% CI 0.484-0.817, P<0.001) were independent influencing factors for all cause mortality. Receiver-operating characteristic curve analysis showed that the area under the curve for male, age and current HBV infection prediction of all-cause death was 0.529 ( P<0.001), 0.724 ( P<0.001) and 0.514 ( P=0.042), respectively, and the cut-off value for age prediction of all-cause death was 65.5 years old. Compared with patients without HBV infection, MHD patients with HBV infection significantly reduced the proportion of severe and critically ill patients, all-cause hospitalizations and all cause deaths when infected with SARS-CoV-2 (4.99% vs. 6.41%, χ2=6.136, P=0.013; 8.90% vs. 11.44%, χ2=11.662, P<0.001; 2.01% vs. 3.37%, χ2=10.713, P=0.001, respectively). Conclusion:The MHD patients in Jiangsu province are susceptible to SARS-CoV-2. Elderly age and male gender are independent risk factors for death in MHD patients during the epidemic, while the HBV infection may be a protective factor for death of MHD patients infected with SARS-CoV-2.
