RESUMEN
With the continuous advancement of health informatization and the wide application of medical big data, electronic health records came into being and spread rapidly. However, because electronic health records contain a large amount of private information, privacy protection is the primary consideration for the sustainable development of electronic health records. By analyzing the shortcomings of privacy protection of electronic health records in law, technology, management and protection consciousness, this paper put forward some countermeasures, such as perfecting the relevant laws and regulations of privacy protection of electronic health records, improving the technical level, improving the management defects of electronic health records, and cultivating the privacy protection consciousness of professionals and the public, so as to improve the overall privacy protection level of China’s health records information management system and provide effective protection for the privacy information of Chinese residents’ electronic health records.
RESUMEN
ObjectiveTo determine the epidemic characteristics of anthrax in Chengde City， Hebei Province from 2005 to 2021， and to provide evidence for formulating prevention and control measures of anthrax and reducing incidence rate. MethodsThis study collected the data of anthrax epidemic in Chengde City and conducted descriptive analysis. ResultsFrom 2005 to 2021， a total of 11 anthrax cases were reported in Chengde City with no death. The average incidence rate was 0.08/105， which remained low. Furthermore， 10 cases were cutaneous anthrax and 1 case was pulmonary anthrax. The cases were mainly reported in Weichang County， accounting for 90.91% of the total reported cases， followed by Pingquan City. In addition， the cases were mainly reported from July to August and mainly between 30 and 59 years old with a gender ratio of 2.67∶1. ConclusionThe anthrax epidemic in Chengde City is likely to increase. It mainly occurs in summer， rural areas， and male young and middle-aged farmers. It is necessary to improve epidemic monitoring， health education， disease prevention capacity， early identification of the epidemic， and active response.

RESUMEN
Objective To investigate the effect of Buyang Huanwu Decoction on blood-brain barrier of focal cerebral ischemia rats, and explore the mechanism of the decoction. Methods The model of focal cerebral ischemia was made by thread embolism method. SD rats were divided randomly into sham-operated group, model group and Buyang Huanwu Decoction group. Buyang Huanwu Decoction group was given Buyang Huanwu Decoction by gavage, the sham-operated group and model group were given normal saline of the same quantity 24 h after modeling. The nervous function deficit scores was evaluated, brain tissues and serum were taken from the rats after treating for seven days, infarct volume was detected by TTC staining, and pathological changes of microvessel were observed microscopically in HE stained sections. And the protein level of MMP-9, MMP-2, VEGF in brain tissue and the serum levels of vWF in serum of every groups were measured by ELISA. Results Compared with model group, Buyang Huanwu Decoction significantly improved the neurological behavior performance, decreased the cerebral infarct volume, alleviated the pathological changes and decreased the protein level of MMP-9, MMP-2, VEGF, vWF. Conclusion Buyang Huanwu Decoction has the protective effect on blood-brain barrier in the model rats of focal cerebral ischemia. The mechanism may be related with restrainning the expression of MMP-9, MMP-2, VEGF, vWF.
RESUMEN
Objective To establish a regenerative system in vitro and determine the endogenous hormones of Zanthoxylum dissitum. Methods Lamina of Z. dissitum was used as the explant. Callus adventitious bud differentiation was carried out by culturing on MS with different hormones. At the same time,in the course of callus induction,four endogenous hormone of GA3,IAA,ABA,and ZR were determined by ELISA. Results The optimum medium for adventitious bud regeneration of Z. dissitum was MS+6-BA 0.5 mg/L+NAA 0.1 mg/L,and the highest induction rate could reach to 61%. During the process of the differentiation of explants callus,the contents of ZR and IAA were correspondingly higher than other endogenous hormones,the content of ABA was always kept in low level during this process,the content of GA3 was kept in the trend of upgrading during the earlier differentiation period. Conclusion It could be considered that ZR and IAA should be the critical factors in the bud induction. According to the results,a proper adding of GA3in the culture medium could improve the differentiation rate of the adventitious bud. On the other side,ABA might be the negative regulation factor.
