Objective:To synthesize 177Lu-prostate-specific membrane antigen (PSMA)-617 with domestic 177Lu (made in China), and explore its optimal labeling condition, biodistribution, stability, and safety. Methods:177Lu-PSMA-617 was prepared with domestic 177Lu by a manual method. The optimal labeling condition, radiochemical purity, stability ( in vivo and in vitro), lipid-water partition coefficient, and plasma protein binding rate were determined. The uptake rate of 177Lu-PSMA-617 was evaluated by using 22RV1 cells. Biodistribution and SPECT/CT imaging were performed on normal mice with imported 177Lu-PSMA-617 as control group. The blood routine test was performed to evaluate the safety. Results:The best labeling result of domestic 177Lu-PSMA-617 can be obtained under the following conditions: pH=4.5, 100 ℃ for 30 min. And the radiochemical purity was ≥99%. The product was stable in vivo and in vitro, with the radiochemical purity >95% in 72 h. The plasma protein binding rate was (35.3±5.3)%, the lipid-water partition coefficient was -2.27±0.06, and the specific uptake rate of domestic 177Lu-PSMA-617 by 22RV1 cells reached the highest in 1 h ((7.58±0.84)%), which was slightly lower than the imported 177Lu-PSMA-617 ((7.86±0.96)%), but there was no significant difference between them ( t=-0.439, P>0.05). The distribution and SPECT/CT imaging of normal mice showed that domestic and imported 177Lu-PSMA-617 in blood were cleared quite fast, and both of them were excreted mainly through the kidneys. No obvious adverse reactions were found in the toxicity test of domestic and imported 177Lu-PSMA-617. There was no obvious abnormality in blood routine and liver and kidney metabolism. Conclusion:The domestic 177Lu-PSMA-617 has many advantages, such as qualified quality control, good biological properties and safety, which support its potential application value in diagnosis of prostatic neoplasms.

Objective To analyze the current status of studies related to home enteral nutrition (HEN) in China,and provide scientific basis for the research and management of HEN in China.Methods We searched CNKI and WanFang Data since it built to January 1st,2018.The included studies were screened and categorized by publication information,study type,subjects of the study,topic,interventions and outcomes.Descriptive analysis was conducted after extraction of information.Results A total of 153 studies were included,of which 37 were observational studies,102 were experimental studies,12 were case report,and 2 were exploring articles.Since 2012,the number of studies has been increasing.Most of the subjects were elderly people who were diagnosed with diseases of digestive system,head and neck tumors and diseases of nervous system.These studies were featured as small sample size and short intervention time,follow-ups by telephone and home visit,less than 1/4 providing professional nutrition support team,and outcomes mainly as complication,nutritional biochemical indices,anthropometric indices and prognosis.Conclusion HEN in China is still in its infancy.The number of relative studies is still small and quality of literatures is very low,but it has been increasing.At present,there are some problems in the implementation of HEN in China,such as lack of standardized management model and professional team,short-term intervention,and single follow-up mode.The elderly and patients with digestive disease,head and neck tumors and nervous disease are the key subjects;more professional nutrition support team and scientific management model should be established in the future.

Hemispherectomy (HS) is an effective surgical therapy to treat refractory epilepsy caused by diffuse hemispheric disorders.After HS surgery, the seizures are often well controlled in patients, and the bilateral limb motor function improves even recovers in some children.This result reveals the strong neuronal plasticity of the brain.The brain, especially of young children, can achieve functional reorganization and cortical remodeling after extensive damage.Multimodal magnetic resonance imaging techniques can jointly analyze the structure and function of the brain and associated neuroimaging features to reveal the neurophysiological mechanisms underlying improved motor function.In this paper, the progress of multimodal magnetic resonance imaging research on motor function alterations in children after hemispherectomy was reviewed.

Objective:The Capital′s Funds for Health Improvement and Research (referred to as ″CFH″), established to address clinical medical issues, have been operating for over a decade. This study aims to comprehensively evaluate the achievements of this fund and provide empirical support and recommendations for optimizing the operational model of the clinical research fund.Methods:An online questionnaire was used to investigate the following aspects of CFH: subject area, the person in charge, derived projects, theses, patents, transformation of results, and popularization and promotion.Results:A total of 745 projects were collected through the online survey, and after rechecking for outliers, 720 completed projects were ultimately included. The top three disciplinary domains, in terms of the number of completed projects, were oncology, cardiovascular diseases, and neurological disorders. The age distribution of project leaders exhibited a left-skewed pattern, with a median age of 45 years. 319 (44%) received support from other related projects subsequently. 95% of the projects resulted in paper publication. 211 (29%) projects applied for patents and copyrights, with 141 projects being granted patent authorization. 78 (11%) projects successfully achieved technology transfer, with transfer and licensing being the most common modes. 156 (22%) projects disseminated their outputs, often targeting secondary hospitals and community health institutions.Conclusions:CFH aligns with local needs, and the outputs are substantial. In the future, consideration can be given to establishing an evaluation mechanism, increasing efforts to promote high-quality outputs, strengthening the organizational model set by the project guidelines, and further improving the rolling support mechanism.

Objective To summarize the phenotypic spectrum of cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) in Fujian population,evaluate the efficiency of the scale and try to adjust it.Methods Thirty-eight CADASIL patients and 64 CADASIL-like patients were recruited based on the CADASIL scale and gene tests,who visited the First Affiliated Hospital of Fujian Medical University and Fujian Neurology Research Institute from May 2011 to November 2017.Their clinical and neuroimaging characteristics were analyzed.Results The migraine,migraine with aura,transient ischemic attack / stroke,early onset age,psychiatric disturbances,cognitive decline,leukoencephalopathy,subcortical infarcts showed no statistically significant differences between the two groups.Instead,compared with CADASIL-like patients (10/64,15.6％;47/64,73.4％;10/64,15.6％),CADASIL patients demonstrated higher percentages of temporal pole involvements (13/38,34.2％;x5=4.716,P=0.030),external capsule involvements (36/38,94.7％;P=0.008) and family history in at least two generations (13/38,34.2％;x2=4.716,P=0.030).According to the scale,the scores showed statistically significant difference between CADASIL (14.84 ± 3.03) and CADASIL-like patients (13.34 ± 3.31;t=2.282,P=0.025) with an area under receiver operating characteristic curve of 0.622.Conclusions CADASIL showed no specific symptoms in Fujian population.The neuroimaging features were proposed to be focused on,especially the external capsule involvements.CADASIL scale could improve diagnostic efficiency,but still needs to be adjusted for Fujian population.The weight value of migraine,migraine with aura and cognitive decline was suggested to be decreased.

Objective:To predict and analyze the number of acute pancreatitis (AP) inpatients based on time series model, and to explore the predictive efficiency of the model.Methods:Clinical data of AP inpatients in the Affiliated Hospital of Southwest Medical University from January 2014 to December 2019 were collected. R software was used to collect the time series of AP inpatients, and the trend and seasonal characteristics of AP inpatients from 2014 to 2018 were analyzed. Furthermore, the autoregressive moving average (ARIMA) model was established through stationarity test, model ordering and model testing steps, and the best selected model was used to predict the monthly number of inpatients in 2019 to verify its prediction efficiency.Results:A total of 3 939 AP patients were included in the study. The most common etiology for AP was cholestrogenic (48.2%), followed by hyperacylglyceremia (36.3%). The peak age of hospitalization was from 40 to 60 years old. Time series analysis showed that the number of AP inpatients increased year by year. The highest peak of the disease was from February to March, followed by September to November; and there was seasonal variation and the incidence was relatively small in summer. The established original training set sequence did not pass the stationarity test ( P=0.061), so the ARIMA model was established after it was transformed into a stationarity sequence by first-order difference. According to the criterion of minimum AIC value, ARIMA(2, 1, 1)(1, 1, 1) 12 was selected as the best model. The model was used to predict the number of AP inpatients in 2019, showing that it could better fit the trend of onset time and had good short-term prediction effect. The mean root error and absolute error were 6.8790 and 4.7783, respectively. Conclusions:The number of AP inpatients increases year by year with seasonal changes. ARIMA model is effective in predicting the number of AP inpatients and can be used for short-term prediction.

The authors with the highest volume of publications in Chinese and English literature are Hu Fulian and Gisbert JP, respectively. The institutions with the highest volume of publications are the First School of Medicine, Beijing University and the Baylor School of Medicine in the United States. The keywords with high centrality in Chinese literature include clarithromycin, eradication rate, drug resistance, amoxicillin, metronidazole, etc. In the analysis of cited literature, it was observed that the Maastricht Consensus report holds an important position in this field.Conclusions:The use of Citespace visualization analysis has intuitively elucidated the research hotspots on the drug resistance of Helicobacter pylori.

Objective:To evaluate the methodological quality and reporting quality of clinical practice guidelines or consensuses in the field of Chinese pancreatic diseases from 2016 to 2021, and provide reference for formulating clinical practice guidelines and consensuses in this field.Methods:VIP, Wanfang , CNKI and CBM databases were searched for articles published from January 2016 to March 2021. The main index terms were " pancreas" , " guideline" , " consensus" , and the supplementary index terms were " pancreatitis" , " pancreatic cancer" , " pancreatic head cancer" . Two researchers independently selected the literature. The appraisal of guidelines for research and evaluation (AGREE-China) was utilized to assess the methodological quality of the guidelines or consensuses, and the reporting items for practice guidelines in healthcare (RIGHT) tool was used to assess the reporting quality.Results:A total of 14 literature were included, including 7 literature on pancreatic cancer, 3 literature on acute pancreatitis, 1 literature on chronic pancreatitis and 3 literature on others. The results of the assessment by the AGREE-China tool showed that there were no document with a total score greater than or equal to 60.0 points, two with 40.0 to 59.9 points, eleven with 20.0 to 39.9 points, and one with less than 20.0 points. Among the results of RIGHT list, basic information was reported the highest(72.62%) and funding and declaration was the lowest(0).Conclusions:The methodological and reporting quality of the guidelines or consensuses on pancreatic disease in China from 2016 to 2021 are generally not high. In the process of developing domestic guidelines or consensuses on pancreatic diseases, the guideline developer should refer to AGREE-China and RIGHT to improve the quality of clinical practice guidelines or consensuses.
