Objective:To study the clinical significance of plasma D-dimer for extended anticoagulation in the elderly patients with hip fracture after discharge.Methods:The data were retrospectively analyzed of the 355 elderly patients with hip fracture who had been admitted to Emergence Center of Trauma and Department of Orthopedic Surgery, The Third Hospital of Hebei Medical University from January 2016 to November 2020. There were 107 males and 248 females with a mean age of 79.0 years (from 65 to 102 years). There were 179 femoral neck fractures, 159 intertrochanteric fractures, and 17 subtrochanteric fractures. Plasma D-dimer concentrations were detected at admission, before surgery, and 35 days after surgery. Color Doppler ultrasonography of deep veins of lower extremities was performed at admission, before surgery, before discharge, and 35 days after surgery. The patients with deep vein thrombosis (DVT) at the time of discharge should were reexamined 15 days after discharge. Strategies for anticoagulation prevention and treatment were formulated according to the patients' plasma D-dimer, color Doppler ultrasonography results, symptoms and signs. Plasma D-dimer concentrations were compared between patients with thrombosis and without thrombosis at different time points.Results:The plasma D-dimer concentrations for the 355 patients at admission, before surgery and 35 days after surgery were 2.73 (1.72, 5.13) mg/L, 1.31 (0.72, 2.58) mg/L, and 0.49 (0.25, 0.80) mg/L, respectively. The level of D-dimer at 35 days after surgery was significantly lower than that at admission and before surgery ( P<0.05). There were, respectively, 105, 126,191 and 148 patients with DVT at admission, before surgery, before discharge and 35 days after surgery, and the DVT was distal in most cases. The D-dimer concentrations for patients with thrombosis and without thrombosis at 35 days after surgery was 0.64 (0.32, 1.00) mg/L and 0.37 (0.22, 0.68) mg/L respectively, showing a significant difference ( P<0.05). The area under the receiver operating characteristic curve of plasma D-dimer for the diagnosis of DVT at 35 days after surgery was 0.665. Conclusions:Extended anticoagulation and continuous monitoring of plasma D-dimer are very important for elderly patients with hip fracture after discharge. For patients with DVT at discharge, negative plasma D-dimer is a sign for termination of anticoagulation; for patients without DVT at discharge, it is reasonable to extend anticoagulation 35 days after surgery.

They can play an important role through VEGF, EGFR, erbB, HIF-1, RAS and other enrichment pathways. 【Conclusion】 The active components of Apocynum venetum leaves can fight against sepsis through multiple targets and multiple pathways.

Objective: To explore the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection who received entecavir alone or in combination with anluohuaxianwan for 78 weeks. Methods: Patients with chronic HBV infection were randomly treated with entecavir alone or in combination with anluohuaxian for 78 weeks. Ishak fibrosis score was used for blind interpretation of liver biopsy specimens. The improvement in liver fibrosis condition before and after the treatment was compared. Student's t test and non-parametric test (Mann-Whitney U-Test and Kruskal-Wallis test) were used to analyze the measurement data. The categorical variables were analyzed by Chi-square test method and Spearman’s rank correlation coefficient was used to test bivariate associations. Results: Liver fibrosis improvement rate after 78 weeks of treatment was 36.53% (80/219) and the progression rate was 23.29% (51/219). The improvement of liver fibrosis was associated to the degree of baseline fibrosis and treatment methods (P < 0.05). The improvement rate of hepatic fibrosis in patients treated with anluohuaxianwan combined with entecavir at baseline F < 3 (54.74%, 52/95) was significantly higher than that in patients treated only with entecavir (33.33%, 16/48), P = 0.016 and the progression rate of hepatic fibrosis (13.68%, 13/95) was lower than that in patients treated alone (18.75%, 9/48), P = 0.466. In patients with baseline F < 3, the proportion of patients with improved and stable liver fibrosis in the combined treatment group (68.1%, 32/47) was higher than that in the treatment group alone (51.7%, 15/29). Conclusion Combined anluohuaxianwan and entecavir treatment can significantly improve the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection. Furthermore, it has the tendency to improve the stability rate and reduce the rate of progression of liver fibrosis.

Recently, salvia miltiorrhiza has made a great progress in research of central nervous system (CNS) injury and neurodegeneration. Salvia miltiorrhiza and its active ingredients can exert multiple effects involving reduction of cell loss, attenuation of oxidative stress, improvement of micro-circulation and promotion of neuroregeneration, and show a protective effect on CNS diseases. Regulation of oxidative stress and removing accumulated metabolite may be the important mechanisms by which salvia miltiorrhiza exerts neuroprotective effects. This study will systematically discuss the pharmacological effects and possible mechanisms of salvia miltiorrhiza based on the core pathological changes in CSN diseases, and evaluate its drug safety through combing the related toxicology researches to provide a reference for clinical transformation of Chinese medicine in threatment of CNS diseases.

Objective: To investigation the situation of cold chain on vaccine in parts of Zhejiang Province and to provide recommendations for the management. Methods: From October to December, 2016, we each selected an immunization clinic in Cangnan County of Wenzhou, Yongkang City of Jinhua, Jianggan District of Hangzhou. Temperature recorder and vaccine viral monitor (VVM) labels were used to monitor the cold chain during all the storage and transportation process. In Jianggan District, we use optical density sensor to detected 20 VVM labels every time when the vaccine was stock in and out. Results: In total, 54 958 records were collected by temperature recording devices in all the three immunization clinic. 275 records exceeded the temperature limit required for store and transportation, of which 270 (98.2%) were above 8 ℃ and 5 (1.9%) were under 2 ℃. Excessive temperature exposure mainly occurred during the transportation (38.2%, n=105), followed by storage process in CDCs at different levels (26.2%, n=72), stock in and out (20.7%, n=50) and storage in the refrigerators in immunization clinics (14.9%, n=41). The average optical density difference between VVM labels and the reference circular decreased from 0.404 to 0.344 when the vaccines were delivered from the Zhejiang provincial CDC to immunization clinics. The color of VVMs did not significantly changed before use. Conclusions The potential risk of vaccine cold chain in the monitoring sites is over-temperature. The weak links of cold chain management include the transportation, storage process, and stock in and out.

Objective To investigate the application of statistical methods in clinical research articles of oncology in China. Methods The core journals in Chinese oncology journals were retrieved in "Wanfang Data", and the application of statistical methods in the clinical research articles published in the first issue of 2017 were analyzed,including the selection of statistical indicators,the selection of statistical methods and the interpretation of statistical results. Results A total of 176 clinical research articles from 24 journals were taken into the study.In the selection of statistical indicators, 12.6 %(16 articles) used the description method of normal distribution data for the skewness distribution measurement data; 37.9 % (47 articles) described the count data with samples<20 as a percentage; 14.5 % (9 articles) replaced the constituent percentages with composition ratios. In the selection of statistical methods, 10.3 % (12 articles) did not perform analysis of variance when comparing among multiple groups, and the t test was used to compare each other directly. 15.1 % (8 articles) disregarded the preconditions of the use of the χ 2test. In the interpretation of statistical results, 18.4 % (27 articles) confused the statistical significance with biological significance. Conclusions The statistical problems are widespread in Chinese oncology clinical research articles,involving the entire process from study design to interpretation of results. Scientific research management departments, clinical researchers, and journal editorial board need to work together to improve the scientificity of clinical scientific research results of oncology in China.
