OBJECTIVE To mine the focus and emotional attitude of the public on rare diseases， and to provide decision- making reference for relevant departments to formulate and implement relevant policies， systems and strategies for medical security of rare diseases. METHODS Latent Dirichlet allocation （LDA） topic model and sentiment analysis method were used to analyze the comment text of short videos related to the “nosinasine” medical insurance admission event on the Bilibili video website， mine the theme and sentiment tendency of the text， and put forward relevant strategy suggestions. RESULTS A total of 8 videos with tens of thousands of playback and 7 109 text data were obtained. According to the LDA analysis， online public paid attention to 9 topics related to rare diseases （the price of rare disease drugs， the inclusion of rare disease drugs in medical insurance， the status quo of research and development of rare disease drugs， the scope of medical insurance and the medical security system， the plight of rare disease patients， the prevention and screening of rare diseases， the value of rare disease drugs in medical insurance， the Chinese and western medical methods of rare diseases， and the supply and demand status of rare disease drugs）， which could be summarized into 4 categories according to the objects of concern （rare disease drugs， rare disease medical insurance， rare disease medical and health services and rare disease patient groups）. On the whole， the emotional tendency of the Internet public towards each topic showed a low positive and high negative tendency. CONCLUSIONS The public paid more attention to the price， research and development， supply and demand of rare disease drugs， and was deeply worried about the current medical status of rare diseases in China. To strengthen and improve the medical security for patients with rare diseases， such as actively carrying out public health services for rare diseases， strengthening cooperation in the diagnosis and treatment of rare diseases， and researching rare disease drugs， etc. Chinese medical and health departments can make concerted efforts in medical and health services， drug supply security， medical security and other social security.

ObjectiveTo analyze the online public Q&A texts on HPV vaccine， focus on the important issues related to HPV vaccination and cervical cancer prevention in China， and propose strategies and suggestions. MethodsThe latent Dirichlet allocation （LDA） topic model was employed to extract key topics of 15 565 Q&A texts related to HPV vaccines from the social Q&A platform "Zhihu". The Baidu AI sentiment analysis tool was used to analyze the emotional tendencies of the texts corresponding to each topic， and the topics were classified based on the strategic coordinate method. ResultsOnline users focused on eight topics about HPV vaccine information. Among them， vaccination knowledge， HPV vaccination hesitation， and HPV vaccine development and marketing belonged to the low positivity-high negativity emotional topics， HPV infection and high-risk factors belonged to the low positivity-low negativity emotional topics， and HPV vaccine appointment channels， comparison between domestic and imported vaccines， HPV vaccines and cervical cancer prevention， and HPV vaccine types and selection were grouped under high positivity-low negativity emotional topics. ConclusionPublic concerns regarding HPV vaccines can be classified into three major dimensions： health knowledge， health beliefs， and health behaviors. Overall， the public's views and attitudes towards vaccine-related issues are not optimistic. Strengthening science publicity and education， enhancing vaccine supervision， and encouraging enterprises’ innovative research and development capability are effective strategies to improve public awareness of cervical cancer prevention and accelerate the full HPV vaccination coverage.

An 82-year-old female patient received monotherapy with nivolumab (240 mg by an IV infusion on the firsr day, 14 days as a cycle) because of multiple metastases of central adenocarcinoma in the right upper lobe of the lung. After 8 cycles of immunotherapy (about 4 months), the patient developed severe nausea and vomiting. Laboratory tests showed random blood glucose 43.2 mmol/L and β-hydroxybutyric acid 5.3 mmol/L. Blood gas analysis showed pH 7.01, bicarbonate root 4.0 mmol/L, alkali residual -22.4 mmol/L, serum potassium 6.1 mmol/L, and lactic acid 2.9 mmol/L. The patient had no previous history of diabetes mellitus. Fulminant type 1 diabetes mellitus due to nivolimab was considered. Nivolumab was stopped and rehydration, hypoglycemia, acidosis correction, and other symptomatic treatments were given. Two days later, her symptoms were improved obviously. Laboratory tests showed fasting plasma glucose 15.8 mmol/L and β-hydroxybutyric acid 0.2 mmol/L. Blood gas analysis showed pH 7.39, bicarbonate root 21.2 mmol/L, alkali residual -3.8 mmol/L, serum potassium 4.3 mmol/L, and lactic acid 1.0 mmol/L.

Objective To investigate the pathological features of ovarian tumors in elderly women.Methods We retrospectively analyzed clinical data of 124 elderly patients with ovarian cancer who were admitted to our hospital from January 2015 to December 2017.Results Among the 124 elderly patients with ovarian tumors,there were 6 borderline tumors,19 malignant tumors,and 99 benign tumors.Postmenopausal vaginal bleeding and lower abdominal pain were the main symptoms of ovarian cancer in elderly patients.The incidence of abdominal pain in patients with benign ovarian tumors was significantly higher than in patients with malignant tumors (x2 =5.813,P ＜0.05);the incidence of postmenopausal vaginal bleeding in malignant tumors was significantly higher than in benign tumors(x2=8.123,P ＜0.05);the major pathological type of benign ovarian tumors was mucinous cystadenoma,while serous cystadenoma was the most common type of malignant tumors.Analysis of related factors showed that menopausal age was positively correlated with,and menarche age and number of pregnancies were negatively correlated with ovarian tumors;and there was no correlation with number of abortions.Conclusions Malignant ovarian tumors are common in elderly women.Clinically,attention to risk factors,early detection and diagnosis will help further reduce the malignant transformation rate and improve the quality of life for patients.

Objective To observe the effect of red light facial synthesis combined with comprehensive facial therapy on corticosteroid dependent dermatitis (hormone dependent dermatitis) and summarize the nursing strategies. Methods About 160 patients with hormone dependent dermatitis hospitalized in our hospital from June 2015 to March 2016, were equally divided into control group and study group:the control group was treated with conventional comprehensive therapy, while the study group with 30 min red light irradiation together with the nursing measures in the control group. The total symptom scores of the two groups were evaluated before treatment and 4 weeks after treatment. Results Before treatment, the total symptom scores of the control group were no significant difference between them (P>0.05). After treatment,the treatment effect of the study group was significantly better than that of the control group and the scores of ISS SSRI were lower than those of the control group . Conclusion The red light radiation combined with comprehensive facial therapy is effective in the treatment of corticosteroid dependent dermatitis and related nursing should be done well to promote patients relovery.
