Objective:To study the epidemiological characteristics and spatio-temporal aggregation of hemorrhagic fever with renal syndrome (HFRS) in Shandong Province, and to provide reference for formulating reasonable prevention and control strategies.Methods:Retrospective analysis was used to collect HFRS surveillance data and confirmed case data in Shandong Province from 2017 to 2020 in the "China Disease Prevention and Control Information System Infectious Disease Surveillance System". Geoda 1.18 software was used for global and local spatial autocorrelation analysis, SaTScan 9.6 software was used for spatio-temporal scanning analysis, and ArcGis 10.7 software was used for map drawing and visual display.Results:A total of 3 753 cases of HFRS were reported in Shandong Province from 2017 to 2020, including 56 deaths. The annual incidence rate was 1.26/100 000, 1.22/100 000, 0.75/100 000 and 0.53/100 000, respectively, with an average annual incidence rate of 0.94/100 000. The incidence of HFRS was obviously seasonal, mainly concentrated in autumn and winter from October to December, accounting for 50.41% (1 892/3 753). The age of onset was mainly 30-59 years old, accounting for 61.68% (2 315/3 753). The male to female ratio was 2.76 ∶ 1.00 (2 756 ∶ 997). The occupation distribution was mainly farmers, accounting for 81.99% (3 077/3 753). The global spatial autocorrelation analysis showed that HFRS showed spatial aggregation areas in each year from 2017 to 2020 (Moran' I = 0.38, 0.33, 0.59, 0.46, Z = 7.47, 7.23, 10.69, 8.66, P < 0.001). The local spatial autocorrelation analysis showed that "high-high" aggregation areas were mainly concentrated in central and southeast of Shandong Province, while "low-low" aggregation areas were mainly concentrated in northwest of Shandong Province. Spatio-temporal scanning analysis revealed 1 type Ⅰ agglomerations and 2 type Ⅱ aggregation areas. The type Ⅰ aggregation areas occurred from October to November 2018, covering 22 counties (districts) of 5 cities in Qingdao, Yantai, Weifang, Weihai and Rizhao. The first type Ⅱ aggregation area occurred from October to November 2017, involving 23 counties (districts) of 8 cities in Jinan, Zibo, Zaozhuang, Weifang, Jining, Tai 'an, Rizhao and Linyi. The second type Ⅱ aggregation area occurred in Jinxiang County, Jining City from February to March 2017. Conclusion:The incidence of HFRS in Shandong Province from 2017 to 2020 has obvious spatio-temporal aggregation, and the hot spots are concentrated in central and southeast of Shandong Province, which should be regarded as a key area for prevention and control of HFRS.

Objective     To summarize the progress and trend on clinical drug trials of esophageal squamous cell carcinoma in China. Methods     Based on the clinical drug trial registration and information disclosure platform and the drug data query system of the National Medical Products Administration, the characteristics of clinical trials, investigational drugs and listed drugs of esophageal squamous cell carcinoma in China from 2012 to 2021 were analyzed. Results     From 2012 to 2021, a total of 49 clinical drug trials of esophageal squamous cell carcinoma were registered in China, accounting for 1.6% of all clinical trials of anticancer drugs. Among them, there were 39 (79.6%) trials initiated by domestic pharmaceutical enterprises, 6 (12.2%) for adjuvant and neoadjuvant treatment, and 9 (18.4%) for local treatment. There were differences in the treatment line distribution between global and domestic enterprise-initiated trials (P=0.032). The above trials covered 29 investigational drugs, including 23 (79.3%) targeted drugs, most of which targeted programmed death-1, programmed death-ligand 1 and epidermal growth factor receptor. From 2012 to 2021, there were 2 drugs for esophageal squamous cell carcinoma listed in China, both of which were approved for the first-line and second-line treatment. Conclusion     Great achievements have been made in the clinical development of esophageal squamous cell carcinoma drugs in China. It is suggested that domestic enterprises increase the investment of esophageal squamous cell carcinoma, pay attention to adjuvant and local treatment, explore novel targets and drug categories, and focus on the details of pivotal trials.

Objective:To evaluate of the general practice residency training bases in Hebei Province.Methods:Based on the 2020 Standardized Residency Training Base Evaluation Index-General Practitioners of Chinese Medical Doctor Association,24 training bases in Hebei Province were assessed;and the satisfaction questionnaire survey and in-depth interview were conducted among 124 general practice trainees who were randomly selected in November 2020. Results:All 24 bases set the general practice department in the hospitals as required. However, the annual outpatient visits in department of general practice were less than 20000 in 45.83% (11/24) bases, only 41.67% (10/24) bases met the teaching requirements of general practice, and 33.33% (8/24) bases fulfilled the provincial target for general practice residency training enrollment; only 3 bases (13.64%) had the pass rate≥85% in medical licensing examination in the previous year. For the training satisfaction, 66.94% (83/124) trainees were satisfied with residency training, and 33.06% (41/124) were moderately satisfied. There was significantly difference in the satisfaction degrees among trainees with different expectations of career prospects (χ 2=24.436, P<0.05). Conclusions:Basically, the management system of general practice residency training bases has been completed and the construction of teaching teams has been standardized in Hebei Province. But the job attraction of general practitioner is inadequate, the training bases need to be strengthened, and the training quality needs to be improved.

Objective:To analyze the current status of faculty development in general practice residency training bases in Hebei Province.Methods:A questionnaire survey with deep interview was conducted among 79 faculty from 24 general practice residency training bases in Hebei Province during November to December 2020.Results:Among 79 participants, 21 were males (26.58%) and 58 were females (73.42%), 41 (51.90%) of whom were aged 31-40 years; 44 (55.70%) were general practitioners, and 35 (44.30%) were specialists. There were no significant differences in sex, age, education background, professional title, between faculty with general practice background and specialist background (all P>0.05); while there were significant differences in job-transfer training, teaching training for general practice, the training form, teaching method grasped, understanding the work contents of general practice, the view and prospect for general practice between general practitioner faculty and specialist faculty (all P<0.05). The score of ward round teaching of general practice faculty was significantly higher than that of specialist faculty ( P<0.05) The interview showed that all faculty members were willing to teach, most of them had increased work pressure after engagement in teaching, and there was lack of incentive policies for teaching in some bases. Conclusions:The current status of faculty development in the general practice residency training base in Hebei Province is basically satisfactory, but there is lack of general practice training for faculty with specialist background; the professional identity of general practitioner need to be enhanced, and their status and treatment need to be improved.

OBJECTIVETo investigate the predominance ticks and the infectious status of severe fever with thrombocytopenia (SFTSV) in Penglai and Laizhou counties, Shandong province.

METHODSTwo towns with high incidence rate were selected in Penglai and Laizhou, respectively, then three villages were selected in each towns. Parasitic ticks were collected from the host skin by hand manually and free ticks manually with white cloth from the grassland, monthly, during April to December in 2011. Samples were classified by original, varieties, developmental stages, then extracted RNA, using Realtime RT-PCR to test severe fever thrombocytopenia syndrome virus, S fragments were amplified with nested PCR, then isolated virus. By neighbor joining method in the phylogenetic tree, the minimum infection rate (MIR) was used to represent the infection status of ticks in novel bunyavirus.

RESULTSA total of 3 145 ticks were collected totally from 5 categories, there were 3 048(96.92%) of Haemaphysalis longicornis, 73(2.32%) of Rhinpicephalus sanguineus, 10(0.32%) of microplus Boophilus, 9(0.29%) of Haemaphysalis campanulata, 5(0.16%) of Dermacentor sinicus, respectively. The positive rate of nucleic acid of 2 044 samples was 6.16% (126/2 044), minimum infection rate (MIR) was 4.01%, there were 122(96.83%) of Haemaphysalis longicornis, 3(2.38%) of Rhinpicephalus sanguineus, and 1(0.79%) of microplus Boophilus, MIR was 4.00%, 4.11%, and 10.00%, respectively. There were no nucleic acid positive samples in Haemaphysalis campanulata and Dermacentor sinicus. The 11 S segments were amplified in 126 positive samples, the homology of S fragment was 95.6%-99.9% with 11 strains isolated from the identified SFTS cases in local area, 3 strains isolated from animals, and 11 strains isolated from other areas. There was no significant difference among original, varieties and developmental stages.

CONCLUSIONHaemaphysalis longicornis was the predominant species in Penglai and Laizhou counties, it could be propagation medium with Rhipicephalus sanguineus and microplus Boophilus, S sequence in ticks was higher homology with virus isolated from local SFTS cases.
