Objective:To analyze the clinical data of histiocytic necrotizing lymphadenitis(HNL),comparing the similarities and differences between children and adults,to deepen the understanding of the disease by clinical physicians,and to improve diagnostic rate and reduce misdiagnosis and mistreat-ment.Methods:The clinical data of hospitalized patients with histiocytic necrotizing lymphadenitis diagnosed by biopsy from January 2010 to August 2023 in Peking University First Hospital were collec-ted,and the clinical features,laboratory examinations,pathological features,treatments with antibiotics and glucocorticoids,and prognosis of histiocytic necrotic lymphadenitis were analyzed.Grouped based on age,the differences of clinical characteristics,laboratory tests,treatment,and prognosis between the children group(＜16 years old)and the adult group(≥16 years old)were compared.Results:Among the 81 enrolled patients,there were 42 males and 39 females.The median age was 21(14,29)years,the median duration of disease was 20.0(13.0,30.0)days,and the median length of hospital stay was 13.0(10.0,15.0)days.The first symptoms were fever,lymphadenopathy,and both.All the patients had enlarged lymph nodes with different parts and sizes,96.3％(78 of 81)of the patients had cervical lymphadenopathy,50.6％(41 of 81)had bilateral cervical lymphadenopathy,55.6％(45 of 81)had supraclavicular,axillary or inguinal lymphadenopathy,and the median lymph node diameter was 20.0(20.0,30.0)mm.Only one patient had no fever,the other 80 patients had fever,the median peak body temperature was 39.0(38.0,39.8)℃.Accompanying symptoms:rash(8.6％,7/81),fatigue(34.6％,28/81),night sweating(8.6％,7/81),chills(25.3％,25/81),muscle soreness(13.6％,11/81),and joint pain(6.2％,5/81).There were 17 cases(21.0％,17/81)of hepatosplenomegaly,of which 12 cases(70.6％,12/17)were splenomegaly.68.8％(55/80)of patients had a decrease in white blood cell(WBC)count,with 47.5％(38/80)increased in lymphocyte(LY)proportion,53.4％(39/73)increased in high-sensitivity C-reactive protein(CRP),79.2％(57/72)increased in erythrocyte sedimentation rate(ESR),22.2％(18/81)increased in alanine transaminase(ALT),27.2％(22/81)elevated in aspartate transaminase(AST),and 81.6％(62/76)elevated in lactate dehydrogenase(LDH).All the 81 patients underwent lymph node biopsy,and 77.8％(63/81)of the patients showed that most of the structures in the lymph nodes were destroyed or disappeared,and 16.0％(13/81)of the lymph nodes were still in existence,hyperplasia and normal lymph node were 1.2％(1/81)respectively,and 3.7％(3/81)had normal lymph node structures.Immunohistochemical staining was performed in 67 cases.The percentages of CD3+and CD68(KP1)+were respectively 97.0％(65/67),and MPO+were 94.0％(63/67).In the study,51 patients(63.0％,51/81)were treated with glucocorticoid therapy after diagnosis.The median time for temperature to return to normal was 1.0(1.0,4.0)days after glu-cocorticoid therapy.when the glucocorticoid treatment worked best,the body temperature could drop to normal on the same day.There were significant differences in length of stay,predisposing factors,chills,the rate of increase in high-sensitivity CRP,antibiotic and glucocorticoid treatment between the adults and children groups(P＜0.05).Conclusion:In clinical practice,if there are cases with unexplained fever,su-perficial lymph node enlargement,and reduced white blood cells as clinical characteristics,and general anti-biotics treatment is ineffective,histiocytic necrotic lymphadenitis should be considered.Lymph node biopsy should be performed as early as possible to clarify the diagnosis,reduce misdiagnosis and mistreatment,and symptomatic treatment should be the main treatment.Glucocorticoids therapy has a definite therapeutic effect.

Objective:To analyze the research hot points and trend of general practice in China.Methods:It was a bibliometric analysis. Research papers presentated on Chinese Society of General Practice from 2014 to 2022 were collected. The distribution and its trend were analysed in terms of titles, submission time, research topics, methods and contents as well as authors′ affilation.Results:A total of 944 research papers were included in the analysis. The results showed a general increasing trend in number of research papers presented on annual conferences from 2014 to 2022 with some fluctuation. The papers covered 28 research dimensions; the highest number of papers was on the development of general practice system, the training and education system for general practitioners, and the construction of information technology (576 papers, 61.0%). The most common topic was on primary health services (230 papers, 24.4%), followed by education and training (225, 23.8%) and chronic disease management (212, 22.5%); while fewer papers were dealing with community-based care (39, 4.1%) and rational medication (7, 0.7%). In terms of the affiliation of the first author, 437 papers (46.3%) were from affiliated hospitals of medical universities/colleges, 223 (23.6%) from community health service institutions, 132 (14.0%) from higher education institutions, 118 (12.5%) from non-affiliated hospitals, and 35 (3.7%) were from administration institutions. In terms of regions, it covered all provinces (municipalities/autonomous regions) (including Hong Kong and Taiwan) with few overseas. Shanghai and Beijing contributed more papers than other regions. In terms of research methodology, most papers used quantitative studies (882, 93.7%), less used qualitative studies (39, 4.1%) or mixed studies (23, 2.4%).Conclusion:The analysis indicates that a wide range of contents are involved in general practice research in China, and more high-quality studies are from medical colleges/universities and their affiliated general hospitals, and most papers use quantitative studies.

Objective:To investigate the experience and perception of general practice residents on standardized training based on stratified progressive teaching model.Methods:From January to April 2022, focus group interviews were conducted among general practice residents who received standardized training at Peking University First Hospital.Results:Seventeen residents were selected by the purpose sampling method in the study, including 7 males and 10 females aged 24-39 years. Four themes were extracted from the interviews: lower levels of basic knowledge and feeling pressure at clinical work felt by junior residents; lack of clinical research ability and systematic training felt by senior residents; the rotation form and teaching contents were mono in grassroots practice bases; desire of raising salary levels for residents.Conclusions:In order to upgrade the quality of general practice residency training, it is necessary to strengthen the knowledge, skill training and research ability training of general practice residents, improve their treatment, and perfect the standardized training program accordingly.

From July to August 2018, a survey on the awareness of diabetic foot screening was conducted using the online questionnaires posted on the WeChat group. From 107 trainees in General Practitioner Teacher Training Program of Beijing Xicheng District and 50 general practitioners working in Chinese Academy of Sciences, 145 valid questionnaires were received. All 145 participants worked in community health care settings, including 105 general practitioners, 76 had 10 to 20 years of service, and 98 had undergraduate degree. The survey showed that 75.9% (110/145) heard the diabetic foot screening and knew that screening should be done for all diabetic patients; 98.6% (142/145) knew that the screening should include medical history, foot skin, neuropathy, vascular status, and 73.1% (106/145) also knew that screening should include the foot bone, joint deformities and footwear selection; 21.4% (31/145) had participated in training related to diabetic foot screening. It is suggested that the awareness and knowledge of diabetic foot screening among Beijing community medical personnelare not sufficient, and more training opportunity is necessary for them.
