Drug therapy is a common method to cure diseases and relieve symptoms.The value of patient-reported outcome(PRO)in evaluating the effect of drug therapy has been increasingly paid attention.The PRO scale is a standardized questionnaire,which can scientifically evaluate the experiences and subjective effects of drug use from a patient-centered perspective,and help patients and clinicians make more reasonable medication decisions.By reviewing and sorting out relevant global literature,this paper found that the content of the PRO scales relevant to drug therapy focused on five fields:"medication satisfaction""medication adherence""drug treatment burden""medication-related quality of life"and"adverse drug reactions".This paper described the basic information,measurement characteristics and application of common scales in recent years respectively,and summarized and analyzed the problems and enlightenment of scale development,aiming to provide theoretical reference for the selection,application and development of PRO scales.

Objective:To explore the differences of clinical features and surgical efficacy between the elderly and the middle-aged and young patients with meningiomas in the central cortex area.Methods:Forty-three elderly patients with meningiomas in the central cortex area (≥60 years old) and 63 middle-aged and young patients with meningiomas in the central cortex area (18-59 years old), accepted surgery in Department of Neurosurgery, Guangdong 999 Brain Hospital from January 2011 to December 2020, were chosen. The differences of symptom, gross tumor volume, peritumoral edema degrees, intraoperative blood loss, tumor resection degrees, complications, and hospital stays between the 2 groups were analyzed.Results:The elderly patients had significantly higher proportion of preoperative muscle strength decline, lower proportion of preoperative headache, larger preoperative tumor volume, more severe peritumoral edema degrees before and after surgery, small volume of intraoperative blood loss, and longer hospital stays compared with the middle-aged and young patients ( P<0.05). However, no significant differences in distributions of tumor resection Simpson grades, proportion of new neurological dysfunction, incidence of postoperative complications, and proportions of reoperations and tumor recurrence were noted between the 2 groups ( P>0.05). Significant difference in distributions of peritumoral edema degrees among patients with different WHO grades was noted in the elderly group ( P<0.05), and significant difference in distribution of peritumoral edema degrees among patients with different tumor volumes was noted in the middle-aged and young group ( P<0.05). Conclusions:Although differences in clinical characteristics exist between the elderly and the middle-aged and young patients with meningiomas in the central cortex area, no significant difference in surgical efficacy is noted between the 2 groups. The peritumoral edema degree in the elderly patients is related to tumor pathological grades, while that in middle-aged and young patients is related to tumor volumes.

Pharmacy services in grassroots medical institutions provide professional pharmacy services for patients. This service not only expanded the scope of primary care delivery, but also meets the residents′need for appropriate medication. At present, the majority of grassroots medical institutions in China provide outpatient pharmacy services by means of pharmacy service alliance, and foreign grassroots medical institutions mainly provide pharmaceutical outpatient services with drug treatment management as the core for patients by granting pharmacists partial prescription rights.In recent years, pharmaceutical outpatient services in grassroots medical institutions had achieved good results in improving patient clinical outcomes, enhancing medication rationality, and enhancing patient compliance. However, there were many unresolved issues, including low public awareness, shortage of pharmaceutical talents, and imperfect guarantee systems. The author suggestted that efforts should be made to increase the publicity of pharmaceutical outpatient services, improve the training mechanism for pharmacists, strengthen cooperation between pharmacists and clinical physicians, include pharmacists in the contracted service team of family doctors, and improve various guarantee systems, in order to provide reference for promoting the sustainable development of pharmaceutical outpatient services in grassroots medical institutions in China.

OBJECTIVE To study the clinical characteristics of leflunomide-induced int erstitial pneumonia （Lef-IP），and to provide reference for its clinical diagnosis ，treatment and prevention. METHODS Lef-IP cases published in domestic and foreign journals from January 2004 to June 2021 were collected. Relevant information of patients were extracted and analyzed retrospectively， including basic characteristics ，clinical manifestations ，imaging manifestations ，laboratory examinations ， histopathological examinations ，treatment and outcome. RESULTS A total of 54 Lef-IP patients from case reports of 24 publications were included ，with a median age of 61 years（9-83 years）. Pulmonary symptoms appeared from 3.3 weeks to 132.9 weeks（median time of 14.5 weeks）. Patients with a loading dose of leflunomide have a shorter median time to pulmonary symptoms appearing （7.5 weeks）. The main clinical manifestations were dyspnea （85.2％），cough（57.4％），fever（53.7％）. CT imaging examination showed 19 cases with ground-glass shadow in both lungs ，and 29 cases showed interstitial infiltration in both lungs on chest radiograph；blood gas analysis showed hypoxemia and hypocapnia ；the levels of C-reactive protein and Krebs von Den lungen- 6 （KL-6）increased；histopathological examination mainly showed interstitial pneumonia （8 cases），including 3 cases of diffuse alveolar injury ，4 cases of lymphocytes in bronchoalveolar lavage fluid ，and 1 case of noncaseating granuloma. After discontinued leflunomide and symptomatic treatment （antibiotics，hormones，colecenamine，plasma exchange ），35 patients（64.8％）recovered or improved their lung symptoms. Twelve patients （22.2％）died，and patients with fever may had a higher mortality rate （34.5％， P＝0.02）. CONCLUSIONS The main clinical manifestations of Lef-IP are dyspnea ，cough and fever. Loading doses of leflunomide should be avoided at the beginning of treatment. When lef-IP occurs ，leflunomide is discontinued and corresponding treatment is given，and most of the patients ’pulmonary symptoms can return to normal or be improved.

Lymphatic leakage and lymphatic cysts are common complications after radical resection of middle- and high-risk prostate cancer. There are many treatment methods but the effect is not accurate. This article reports two patients who were diagnosed by lipiodol lymphangiography under ultrasound guidance and used a mixture of n-butyl cyanoacrylate and lipiodol to embolize lymphatic leakage. Among them, one patient achieved success after one session of interventional embolization. Another patient achieved success after 3 interventions and embolization. Two patients had no complications related to lymphatic interventional therapy, and no lymphatic leakage recurred during the 3-month follow-up. Ultrasound-guided lymphangiography and lymphatic embolization through the inguinal lymph nodes are a feasible option for the treatment of refractory lymphoma leakage

Objective:To summarize the experience of Bacillus Calmette-Guerin(BCG) in the treatment of bladder cancer secondary to renal transplantation.Methods:The clinical data of 5 patients who underwent BCG bladder irrigation after secondary bladder cancer after kidney transplantation in Tianjin First Central Hospital from January 2015 to December 2019 were analyzed. There were 1 male and 4 female cases. During the period of immunosuppression after transplantation, 1 case developed secondary high-level non-muscular invasive bladder cancer (NMIBC), 3 cases developed secondary low-grade NMIBC, and 1 case developed secondary glandular cystitis (4 cases). The mean age of the 5 patients with secondary bladder cancer was 59.7±4.0 years. Case one with high level NMIBC was treated with transurethral resection of bladder tumor (TURBT) and postoperative irrigation of epirubicin. Case 3 and 5 with low-level NMIBC accepted regular postoperative irrigation of gemcitabine. No irrigative therapy was performed in case 2. Bladder cancer recurred in case 1, 2, 3 and 5 after 20.1±9.7 months. TURBT was observed in all the 4 patients, among which 3 were of high grade NMIBC and 1 was of low grade NMIBC. Four patients were irrigated with BCG 2 weeks after operation. Postoperative pathology indicated low-level NMIBC in case 4, and BCG was irrigated 2 weeks after the operation. During perfusion therapy, immunosuppressive agents were continued.Results:During BCG perfusion, 4 of the 5 cases showed BCG related local inflammation, among which 2 cases presented symptoms of bladder irritation, 1 case presented hematuria, and 1 case presented hematuria with low fever. Patients with frequent urination, pain in urine, hematuria and other symptoms improved after drinking plenty of water, taking bed rest and taking levofloxacin (0.5g/ day ×7 days). Patients with low fever were treated with antipyretic treatment. No antituberculous agents were used prophylactically during BCG perfusion. There were no symptoms of tuberculosis infection or sepsis. The function of transplantated kidney was normal and no tendency of rejection. The 5 patients were followed up for 7-24 months, 1 patient was lost to follow-up after 7 months of BCG bladder perfusion, and no tumor recurrence or metastasis was found in 5 patients during the follow-up.Conclusions:The use of immunosuppressive agents does not reduce the biological activity of BCG, and BCG does not increase the risk of systemic toxicity or affect the function of transplanted kidneys in immunocompromised patients. BCG is a treatment option for bladder cancer secondary to renal transplantation.

Artificial intelligence (AI) is a general term that refers to the use of a machine to imitate intelligent behavior for performing complex tasks with minimal human intervention, such as machine learning; this technology is revolutionizing and reshaping medicine. AI has considerable potential to perfect health-care systems in areas such as diagnostics, risk analysis, health information administration, lifestyle supervision, and virtual health assistance. In terms of immunotherapy, AI has been applied to the prediction of immunotherapy responses based on immune signatures, medical imaging and histological analysis. These features could also be highly useful in the management of cancer immunotherapy given their ever-increasing performance in improving diagnostic accuracy, optimizing treatment planning, predicting outcomes of care and reducing human resource costs. In this review, we present the details of AI and the current progression and state of the art in employing AI for cancer immunotherapy. Furthermore, we discuss the challenges, opportunities and corresponding strategies in applying the technology for widespread clinical deployment. Finally, we summarize the impact of AI on cancer immunotherapy and provide our perspectives about underlying applications of AI in the future.

Objective:To explore the effect of the Internet combined pre-rehabilitation intervention model in patients with chronic hepatitis B liver cirrhosis.Methods:From June 2019 to December 2020, convenience sampling was used to select 140 patients with chronic hepatitis liver cirrhosis in Henan Provincial People's Hospital. The patients were randomly divided into the observation group and the control group according to the order of entry, 70 cases in each group.The observation group carried out the Internet combined pre-rehabilitation model and the control group implemented conventional nursing intervention. We compared the disappearance time of clinical symptoms, mastery of rehabilitation knowledge and the quality of life of the two groups of patients.Results:The disappearance time of abdominal distension, ascites, anorexia, fatigue, and lower extremity edema of the observation group was shorter than that of the control group, and the differences were statistically significant ( P<0.05) .After the intervention, the disease knowledge such as reasonable work and rest, reasonable diet, emotional control, exercise and medical treatment of observation group was better than that of the control group, and the differences were statistically significant ( P<0.05) . After the intervention, the quality of life scores of patients in the observation group were higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The Internet combined pre-rehabilitation intervention model can shorten the disappearance time of clinical symptoms in patients with chronic hepatitis B liver cirrhosis, improve the patient's knowledge of disease rehabilitation and the quality of life, which is worthy of clinical application.

Objective: To investigate the role of HIV-1 envelope protein gp120 in cognitive impairment induced by neuronal damage. Methods: Western blot and immunofluorescence assay were used to detect microglia activation, inflammatory factor expression and neuronal damage after gp120 treatment. Neuronal damage and neurocognitive performance in gp120-transgenic mice were evaluated using immunohistochemical staining and behavioral analysis, respectively. Results: In vivo and in vitro experiments showed that HIV-1 gp120 significantly induced the expression of caspase-1 and IL-1β, and indirectly caused neuronal synaptic shortening and neuronal damage (P<0.05). Compared with wild-type mice, gp120-transgenic mice showed significant cortical and hippocampal glial activation, neuronal loss, dendritic damage and neurocognitive disorders. Conclusions HIV-1 gp120 might cause neuronal damage through activating the release of inflammatory factor by microglia and involve in neurocognitive impairment.

Objective:To analyze the clinical features and follow-up results of children with acute exogenous lipoid pneumonia (ELP), and to investigate the diagnosis strategy, treatment and risk factors of ELP.Methods:The clinical features, imaging manifestations, results of bronchoalveolar lavage fluid (BALF), treatment methods and prognosis of 41 ELP inpatients in Guangzhou Women and Children′s Medical Center, Guangzhou Medical University from May 2013 to May 2018, were summarized and analyzed, and the related literature was reviewed.Results:(1) Among 41 patients, 29 cases were male and 12 cases were female.The age of onset ranged from 4 to 53 months.Most of them (35/41 cases, 85.4%) were less than 3 years old, and the majority were aged 1 to 2 years (23/41 cases, 56.1%). (2) The grease taken by children by accident included perfume oil (11 cases), white electric oil (7 cases), electric mosquito oil (5 cases), lubricating oil (5 cases), paraffin oil (4 cases), gasoline/diesel oil (3 cases), kerosene (2 cases), cod-liver oil (2 cases), sewing machine oil (1 case), and unclear oil (1 case). (3) The main clinical manifestations were cough (26/41 cases, 63.4%), shortness of breath (23/41 cases, 56.1%), fever (17/41 cases, 41.5%), cyanosis with hypoxemia (15/41 cases, 36.6%), wheezing (9/41 cases, 22.1%), respiratory distress (9/41 cases, 22.1%), pulmonary hemorrhage (6/41 cases, 14.7%), feeding difficulties and transient vomiting (4/41 cases, 9.8%). Some cases showed no symptoms (3/41 cases, 7.3%). (4) Chest X-ray mainly showed bilateral pulmonary exudative changes or pulmonary consolidation.The most common sign of high-resolution computerized tomography (HRCT) was local or extensive exudation, often accompanied by pulmonary consolidation (18/41 cases, 43.9%). The most common affected sites were bilateral lower lobes (8/41 cases, 19.5%), followed by right lower lobes (3/41 cases, 7.3%), right middle lobes (2/41 cases, 4.8%) and left lower lobes (2/41 cases, 4.8%). Other signs included alveolar changes, hyperventilation, ground glass changes, and nodule formation.(5) Seven children needed mechanical ventilation due to respiratory failure, and all patients underwent bronchoalveolar lavage (BAL). All patients recovered without death, with (11.67±4.90) days of hospitalization, and the hospitalization time of ELP patients with adenovirus infection was (19.25±5.93) days.Nine of them were lost to follow-up (8 cases were mild and 1 case was severe). The symptoms of the remaining children disappeared within 1 week to 1 month.The lung images of 21 cases returned to normal within 1 month after discharge, 7 cases returned to normal within 3 months after discharge, and 4 cases returned to normal after 6 months.Conclusion:The clinical manifestations and lung imaging of children with acute ELP have no specificity.Pulmonary imaging of severe patients shows multiple lobes involved, and consolidation and vacuolar changes may occur.Most patients have a favorable prognosis.Co-infection, especially adenovirus infection, may be a risk factor for acute ELP in children.BAL can play a role in both diagnosis and treatment, and its combination with local/systemic glucocorticoid therapy is effective for severe acute ELP.
