Objective: To investigate the utilization status of epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) in 11 hospitals of Zhejiang province from 2009 to 2015, and to analyze the use rationality.Methods: The doctor's advice in 40 days annually was collected in 11 hospitals of Zhejiang province from 2009 to 2015, and the drug consumption, frequency of utilization (DDDs), defined daily cost (DDC) and drug utilization index (DUI) were analyzed for the patients with lung cancer treated with EGFR-TKI.Results: Icotinib, erlotinib and gefitinib were the three prevalent EGFR-TKIs used in Zhejiang province, and icotinib started to be used in clinics in 2013.The overall cost of EGFR-TKIs increased year by year during 2009 and 2015, and the total amount of sales increased by 4.67 times in 2015 when compared with that in 2009.Generally, the DDDs value of erlotinib showed a decreasing trend, however, that of icotinib and gefitinib rose year by year during 2009 and 2015.Erlotinib had the highest DDC followed by gefitinib and icotinib.The mean value of DUI of the three targeted drugs was about 1.Conclusion: The utilization of EGFR-TKI is reasonable in 11 hospitals of Zhejiang province with increasing comsuption.

Objective:To understand the current situation and influencing factors of successful aging in widowed elderly.Methods:From May to October 2019, 225 widowed elderly people were investigated by questionnaire in 7 communities and 5 villages in Shandong Province. The Successful Aging Scale of the Flood was used to assess their successful aging status. The general data sheet, Physical Activity Scale for the Elderly (PASE), Multidimensional Scale of Perceived Social Support(MSPSS), Connor-Davidson Resilience Scale (CD-RISC) and Mini Mental State Examination(MMSE) were used to measure its influencing factors.Results:The successful aging score of the widowed elderly was 46.22 ± 9.49. The results of multiple linear regression analysis showed that the influencing factors of the successful aging of the widowed elderly were: social activity participation, household registration, consciously successful aging status, psychological resilience, MMSE—attention and computing power, perceived social support—other people, leisure physical activity, which can explain a total of 70.7% of the regression equation.Conclusions:The successful aging status of widowed old people is at a low level, and its influencing factors have both common factors and specific characteristics compared with those with spouses. In particular, more attention should be paid to "participation in social activities", and the widowed old people should be actively encouraged to participate and improve their successful aging.

Objective:To investigate the immune effects of Clostridium difficile toxoid B (CdtB) vaccine formulated with different mucosal adjuvants through microneedle immunization, and to provide ideas for the prevention and treatment of Clostridium difficile infection. Methods:CdtB vaccine was prepared with purified Clostridium difficile toxin B(TcdB) after formaldehyde detoxification. Female BALB/c mice were immunized with different doses of vaccine alone or in combination with mucosal adjuvants. The titers of specific serum IgG and fecal IgA were detected at 0 d, 7 d, 14 d, 28 d and 42 d after immunization. The protective effects of CdtB vaccine were evaluated by cell neutralization assay and Clostridium difficile challenge infection. Results:(1) With the increase of immune dose, the mice immunized with CdtB vaccine alone by microneedle not only produced better serum specific IgG, but also had higher level of IgA in feces. (2) When the mice were immunized with CdtB vaccine containing LT or CTB adjuvant by microneedle, the trend of serum specific IgG titer in each group increased with the increase of immune dose, especially in the group containing LT adjuvant. There were significant differences in the trend of specific IgA titer in feces between the adjuvant groups and the group without adjuvant, but the adjuvant effect was not obvious. (3) No significant difference in serum IgG titer was observed between the mice immunized with 10 μg CdtB by microneedle or intraperitoneal injection, but microneedle immunization significantly increased fecal IgA level. (4) The neutralization titers of specific antibodies in mouse serum after immunization and the test results of challenge protection in mice confirmed that the use of CdtB vaccine had certain protective effects.Conclusions:CdtB vaccine had better immune effects in mice through microneedle immunization, but the adjuvant effects of LT and CTB were not significant.

Successful aging is an important strategy to actively deal with aging as well as a crucial measure to maintain national security and social harmony and stability, and the assessment of successful aging is the prerequisite and basis for relevant measures. However, standardized assessment tools for successful aging have not yet been formed by far, which has had a certain impact on the in-depth research in successful aging. This article summarizes and analyzes the comprehensive assessment methods and tools for successful aging at home and abroad, and provides references for the research into comprehensive assessment tools for successful aging, with a view to promoting the formation of standardized and comprehensive assessment tools for successful aging and developing comprehensive assessment tools for successful aging for Chinese elderly based on China's conditions.

With the development of medical technology, the fixation method of the oral duct is constantly updated, and the selection of a relatively safe, effective, simple and fast fixation method of the oral duct has been widely concerned. However, the use of traditional 3M I-shaped tape fixation needs to be cut, which wastes time and easily leads to the outward displacement of the tracheal tube, and is easy to be soaked by oral secretions, resulting in facial skin damage. Therefore, the medical staffs of the department of critical care medicine of Hengshui People's Hospital designed a self-made tracheal catheter fixing band (composed of the main structure, the fixed band, the internal adjusting structure and the internal structure of the fixed block), and obtained the national utility model patent (ZL 2018 2 0508681.6). The inner side of the fixing band is fixed with a spongy body, which can absorb the secretions around the mouth to avoid the moist condition around the mouth and cheek skin. Meanwhile, the endotracheal catheter is fixed with the help of the card slot, hinge and other structures, which can fully ensure the fixation effect. A total of 80 patients undergoing airway intubation were admitted to the department of critical care medicine of our hospital from October 2020 to September 2021. They were divided into observation group and control group according to intubation time (single number and double number), with 40 patients in each group. The observation group was fixed with self-made tracheal catheter fixation band. Through evidence-based practice path, relevant literatures at home and abroad were searched for clinical practice basis, and the practice plan was formulated and implemented. The control group was fixed with 3M tape + inch tape according to the traditional method. The fixation of tracheal tube and the degree of facial skin injury were compared between the two groups. All patients were included in the final analysis without shedding cases. Severe catheter displacement occurred in 3 patients (7.5%) in the control group, and no severe catheter displacement occurred in the observation group. The incidence of facial skin injury in the observation group was significantly lower than that in the control group [25.0% (10/40) vs. 55.0% (22/40), P < 0.05]. Moreover, the fixation time of the observation group was significantly shorter than that of the control group (minute: 12.11±1.69 vs 17.59±1.27, P < 0.05). The application of self-made tracheal catheter fixation band can shorten the fixation time of tracheal catheter and reduce the incidence of unplanned endotracheal extubation (UEE) and facial skin injury, which is worthy of clinical promotion and application.
