Objective  To establish and evaluate the clinical teaching and training model for refresher anesthesiologists.  Methods  A total of 25 refresher anesthesiologists from the Department of Anesthesiology in Peking Union Medical College Hospital during the period of March to September 2023 were enrolled. They were taught with the clinical teaching and training model, namely "tutorial system-knowledge update-clinical practice". The refresher anesthesiologists completed the same structured pre-designed questionnaire at the beginning and the end of training respectively. The scores were recorded and compared to evaluate the effectiveness of the clinical training model. Feedback from refresher anesthesiologists about the teaching and training model was also collected.  Results  Altogether 84%(21/25) and 100%(25/25) of questionnaires distributed were completed respectively, and 92% students gave positive feedback. The mean score at the end of training (10.1±1.1) was significantly higher than that at the beginning (5.6±1.8)(P < 0.01).  Conclusion  The "tutorial system-knowledge update-clinical practice" clinical teaching and training model was significantly useful to elevate the effectiveness of training refresher anesthesiologists and their satisfaction.

Objective:To explore the correlation between high cholinergic pathway signaling and cognitive function in patients with Parkinson disease(PD) accompanied with sleep disorder.Methods:PD patients admitted from 2017 to 2022 were divided into PD with sleep disorder group (PD-SD group) ( n=56) and PD without sleep disorder group (PD-NSD group) ( n=41) according to the Parkinson's disease sleep scale (PDSS) score. All participants underwent magnetic resonance imaging examination.All patients were evaluated by the PDSS, Hoehn-Yahr (H-Y), Montreal cognitive assessment scale (MoCA), and cholinergic pathways hyper intensities scale (CHIPS). The difference of cognitive function between the two groups and the correlation between CHIPS and cognitive function were analyzed.Independent sample t-test, Spearman correlation analysis, and binary Logistic regression analysis were performed on the data by SPSS 26.0 statistical software. Results:(1)The MoCA score of the PD-SD group (22.00 (5.00)) was lower than that of the PD-NSD group (26.00 (5.00)) ( Z=-3.830, P<0.05). The total and all aspects scores of CHIPS in PD-SD group were higher than those in PD-NSD group(the total score of the low external capsule: 12.00(8.00), 0(8.00), the total score of the high external capsule: 12.00(2.00), 6.00(9.00), the total score of the radial crown: 8.00(0), 4.00(4.00), the total score of the centrum semiovale: 3.00(4.00), 0(2.00), the total score of the right side: 16.00(9.00), 5.00(10.00), the total score of the left side: 17.00(6.00), 7.00(9.00), the total score of CHIPS: 32.00(14.00), 14.00(20.00))( Z=-5.081, -5.873, -4.933, -3.211, -5.562, -6.232, -5.995, all P<0.05). (2)The correlation analysis between the score of CHIPS and cognitive function in the PD-SD group showed that, the total score of the low external capsule ( r=-0.286), the total score of the centrum semiovale ( r=-0.307), the total score of the right side ( r=-0.376), the total score of the left side ( r=-0.284) and the total score of CHIPS ( r=-0.349) were negatively correlated with MoCA(all P<0.05). (3)Binary Logistic regression analysis showed that white matter lesions in centrum semiovale, low inner capsule, right and left leukodystrophy were not influence factors for cognitive impairment (all P>0.05). Conclusion:PD patients with sleep disorders have lower cognitive function scores, higher CHIPS scores, and significant changes in white matter lesions compared to those without sleep disorders. In PD patients with sleep disorders, the higher the CHIPS score, the lower the cognitive function score, and the more significant the rate of cognitive impairment occurrence and development.

Objective To observe the clinical efficacy of Feisu Granules,and its effects on quality of life,coagulation and immune function in acute exacerbation of chronic obstructive pulmonary disease(AECOPD)with syndrome of phlegm-heat and blood stasis of lung.Methods Totally 120 AECOPD patients were divided into observation group and control group according to random number table method,with 60 cases in each group.The control group was given conventional Western medicine treatment,and the observation group received Feisu Granules treatment on the basis of the control group,one bag each time,three times a day,orally.The treatment for both groups lasted for 7 d.The clinical efficacy of both groups were observed.TCM symptom scores,St.George's respiratory questionnaire(SGRQ)score,coagulation function indexes(fibrinogen,D-dimer),and immune function indexes(CD4+,CD8+,CD4+/CD8+)of both groups were compared.The side effects were observed.Results The total effective rate in the observation group(93.10%)was significantly higher than that of the control group(79.66%),with statistical significance(P<0.05).Compared with before treatment,TCM symptom scores,scores of cough,wheezing,venous congestion,and SGRQ score decreased in both groups after treatment(P<0.05);after treatment,the observation group had lower above scores than the control group(P<0.05).Compared with before treatment,both groups showed a decrease in plasma fibrinogen and D-dimer levels after treatment(P<0.05);after treatment,the observation group showed lower levels of plasma fibrinogen and D-dimer compared with the control group(P<0.05).Compared with before treatment,the peripheral blood CD4+ and CD4+/CD8+ levels in both groups significantly increased after treatment,while CD8+ levels significantly decreased(P<0.05);after treatment,the peripheral blood CD4+ and CD4+/CD8+ in the observation group were higher than those in the control group,while CD8+ was lower than those in the control group(P<0.05).Neither group had any drug-related side effects.Conclusion On the basis of conventional Western medicine,the combination of Feisu Granules in the treatment of AECOPD with syndrome of phlegm-heat and blood stasis of lung can significantly improve clinical efficacy,improve patient quality of life,facilitate coagulation function recovery,and enhance cellular immune function.

Objective:To investigate the development of receptive and expressive vocabulary in Mandarin-speaking children with cochlear implants (CI) during the first year after CI activation.Methods:A total of 827 children (411 boys and 416 girls) who were implanted CI before 2.5 years of age from October 2019 to December 2022 in the Department of Auditory Implantation, Shandong Provincial ENT Hospital were included in this study. The Infant Checklist of the Mandarin Early Vocabulary Inventory (EVI) was used to assess the quantity and content of receptive and expressive vocabulary at the time of CI activation and at the 1st, 3rd, 6th, 9th, 12th months post-activation. SPSS 22.0 was used to describe the receptive and expressive vocabulary of CI children at the first year after activation.Results:During the first year after CI activation, CI children′s receptive and expressive vocabulary consistently increased with the CI usage. The average number of receptive vocabulary and expressive vocabulary respectively increased from 0 to 178, and from 0 to 97. At the first year of post-activation, the number of receptive and expressive vocabulary of CI children were superior to that of hearing-age matched typical-hearing children, but fell behind of that of chronological age matched typical-hearing children. In terms of lexical categories, receptive and expressive vocabulary was acquired in the following order: nouns, verbs, adjectives, and pronouns. Among the top 50 words that CI children could express, nouns were the most common, then followed by verbs, adjectives, and pronouns. Father′s education level can significantly and positively predictethe receptive vocabulary of CI children at the first year post-activation. At the first year after CI activation, the 10th, 25th, 50th, 75th, and 90th percentiles were 113, 149, 178, 202, 223 for the receptive vocabulary, and 9, 37, 97, 148, 188 for expressive vocabulary.Conclusion:For Mandarin speaking children with CI, the receptive and expression vocabulary continuely increased within the first year after CI activation. The ability to grasp receptive vocabulary precedes the ability to express expressive vocabulary. Compared to hearing-age matched typical-hearing children, CI children showed faster rate of the vocabulary growth, and earlier and more frequently verb expression. However, it still larged behind that of chronological age matched hearing normal children. CI children respectively understood and expressed nouns and verbs the first. In children with CI, the first concepts understood and expressed were nouns and verbs. Among the first 50 words expressed, nouns were the most numerous, and the age at which verbs were acquired was earlier than that for hearing-age matched typical-hearing children.

A total of 26 pieces of evidence were summarized, including 5 aspects, including applicable population, exercise evaluation, exercise plan, exercise precautions and exercise management.Conclusions:The best evidence summarized in this study provides a basis for the development and management of exercise intervention in patients with multiple myeloma. It is suggested that clinical staff should fully consider the clinical context when applying the evidence, and develop personalized exercise intervention programs based on the patient′s status and preferences.

Objective:To study the infection and epidemiological characteristics of soil borne nematode disease in Sihong County, Suqian City, and to provide scientific basis for further development of prevention and control measures.Methods:In 2022, according to geographic location, Sihong County was divided into east and west areas. Jieji Town, Shiji Township, and Linhuai Town were selected from the east area, and Tianganghu Township, Meihua Town from the west area. One administrative village was selected as a survey point in each township. Using cluster sampling method, 450 permanent residents aged 3 years old and older in the village were selected as the respondents for questionnaire survey and fecal sample collection. The infection status of hookworms, roundworms, whipworms and pinworms in fecal samples were examined, transparent tape anal swab method for detecting pinworm eggs in children, and influencing factors were analyzed.Results:A total of 2 264 survey subjects were included, 18 cases of soil borne nematodes were detected as positive, with an overall positive rate of 0.80%. Among them, 15 cases were positive for hookworms, 1 case was positive for whipworms, and 2 cases were positive for pinworms, with detection rates of 0.66%, 0.04%, and 0.09%, respectively. No ascaris lumbricoides were detected. Transparent tape anal swab method was used to examine 142 children, and the positivity rate of 1.41% (2/142). By township, the detection rate of soil borne nematodes was the highest in Jieji Town, at 2.41% (11/457); the others were Meihua Town, Tianganghu Township, Shiji Township, and Linhuai Town, with detection rates of 0.89% (4/451),0.66% (3/454), 0 (0/451) and 0 (0/451), respectively. There was a statistically significant difference between different townships (χ 2 = 19.21, P < 0.001). Among the 18 positive cases of soil borne nematode, 7 were males and 11 were females, with detection rates of 0.66% (7/1 063) and 0.92% (11/1 201), respectively, the difference was not statistically significant (χ 2 = 0.47, P = 0.491). The age distribution showed the highest detection rate in the 40 - < 60 age group, at 1.42% (9/634), with statistically significant differences between different age groups (χ 2 = 6.41, P = 0.033). The occupational distribution showed the highest detection rate in farmers, at 1.46% (9/617), with statistically significant differences between different professions (χ 2 = 8.00, P = 0.034). The differences in total soil borne nematode and hookworm detection rates were statistically significant among different methods of treating human and animal feces (χ 2 = 11.01, 9.02, P = 0.003, 0.011). Conclusions:The main species of soil borne nematode infections in Sihong County, Suqian City are hookworms, with fewer infections of whipworms and pinworms, and no roundworm infections observed. There are regional differences in detection rate. In the future, it is necessary to strengthen health education for key populations, enhance health knowledge publicity, and effectively intervene to change unhealthy production and lifestyle, further reducing the infection of soil borne nematodes in Suqian City.

Objective To explore the pulmonary ultrasound manifestations of pediatric infectious pneumonia and its combined diagnostic value with serum amyloid protein A(SAA)/hypersensitive C-reactive protein(hs-CRP)and procalcitonin(PCT).Methods A tatol of 107 children with infectious pneumonia admitted to the 903rd Hospital of the Joint Logistics Support Force of the People's Liberation Army of China from January 2019 to June 2023 were selected as the research group,and 50 healthy children who underwent physical examinations during the same period were selected as the control group.Both groups of children underwent lung ultrasound examination to analyze the ultrasound manifestations of children with infectious pneumonia,compare SAA/hs-CRP and PCT,and analyze the diagnostic value of lung ultrasound combined with SAA/hs-CRP and PCT detection for pediatric infectious pneumonia.Results Among 107 children with infectious pneumonia,104 were diagnosed positive by lung ultrasound,with a positive rate of 97.20％.The lung ultrasound score,SAA/hs-CRP,and PCT of the study group were higher than those of the control group(P＜0.05).The lung ultrasound score,SAA/hs-CRP,and PCT in children with severe infectious pneumonia were higher than those in mild cases(P＜0.05).The diagnostic efficacy of lung ultrasound combined with SAA/hs-CRP and PCT detection for pediatric infectious pneumonia is superior to that of individual detection,with a curve area of 0.923,sensitivity and specificity of 92.30％and 87.98％,respectively.The lung ultrasound score is positively correlated with SAA/hs-CRP and PCT(P＜0.05).Conclusion Pulmonary ultrasound can display the characteristics of pulmonary lesions in children with infectious pneumonia.The ultrasound manifestations of children are mostly abnormal pleural lines,increased B-lines,and pulmonary consolidation.Combined detection with SAA/hs-CRP and PCT can further improve the diagnostic efficiency of pediatric infectious pneumonia.

Objective:To further explore the symptom experience and coping strategies of patients with multiple myeloma, so as to provide reference for the formulation of symptom management programs.Methods:Objective sampling method was used to conduct semi-structured in-depth interviews on 15 patients with multiple myeloma in Hematology Department of Nanjing Drum Tower Hospital from December 2021 to June 2022 and the model of symptom management theory was used as the framework to construct an interview outline. The Colaizzi 7-step analysis method was used to analyze data and extract themes.Results:Three main themes were summarized: symptom experience (obvious symptom perception, poor symptom assessment ability, negative symptom response); symptom management strategy (vague knowledge of symptom management, hope to get professional guidance, expect to get continuity of management); symptom management outcomes (recurrent anxiety, reordering, adaptive behavior).Conclusions:Patients with multiple myeloma have diverse and complex real symptom experience in different periods. Medical staff should pay attention to patients′ symptom response and coping needs and develop a systematic symptom management plan, so as to help them create better self-management and improve their quality of life.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

Objective:To explore the risk factors of acute kidney injury(stage 3)developed within 48 hours in elderly patients with sepsis, and to use them to develop a risk prediction model and then evaluate and externally validate the model.Methods:Clinical data of all elderly patients(age≥ 60 years)with sepsis in the intensive care medicine information database(MIMIC-Ⅳ v1.0)were extracted.Independent risk factors were determined by multivariate logistic regression analysis.A risk prediction model was constructed, a nomogram was drawn, and the receiver operating characteristic curve(ROC)and the Hosmer-Lemeshow(H-L)test were used to evaluate the model's prediction accuracy and R-squared.Clinical data of elderly patients(age≥ 60 years)with sepsis admitted to the Department of Critical Care Medicine of the Second People's Hospital of Hefei from May 2019 to October 2021 were retrospectively collected and fed into the prediction model to conduct external validation.Results:A total of 1 977 elderly patients with sepsis were screened out from the MIMIC-IV database and included in the training set, of whom, 544 developed AKI-stage 3 within 48 hours.Univariate analysis was performed for factors that might be associated with acute kidney injury in elderly patients with sepsis.Compared with the normal group that did not progress to AKI stage 3, there were statistically significant differences in 28 indicators, such as the duration of ICU stay, intravenous fluid intake in 24 hours, and use of vasoactive drugs[5(3, 9)d vs.7(4, 12)d; 2.05(1.17, 3.27)ml·kg -1·h -1vs.2.37(1.47, 4.10)ml·kg -1·h -1; 761(53.11%) vs.375(68.93%), P<0.001]. Based on the results of multivariate logistic regression analysis, a prediction model was finally constructed with 9 variables: albumin( OR=0.983, 95% CI: 0.966-0.999, P=0.040), aspartate transaminase( OR=1.000, 95% CI: 1.000-1.000, P<0.001), APTT( OR=1.005, 95% CI: 1.001-1.009, P=0.028), total bilirubin( OR=1.003, 95% CI: 1.001-1.004, P=0.001), serum creatinine( OR=1.005, 95% CI: 1.004~1.007, P<0.001), Charlson score( OR=1.117, 95% CI: 1.061-1.177, P<0.001), intravenous fluid intake in 24 hours( OR=1.101, 95% CI: 1.034-1.173, P=0.003), weight( OR=1.023, 95% CI: 1.018-1.029, P<0.001), and mechanical ventilation( OR=2.412, 95% CI: 1.843-3.157, P<0.001). Then a nomogram was generated.The area under the ROC curve(AUC)of the prediction model was 0.755(95% CI: 0.731-0.780), and the H-L test was conducted( χ2=10.89, P=0.208>0.05), indicating a good fit.Data from 102 elderly patients were included in the validation set, with 27 cases that had developed AKI-stage3 within 48 hours, and were fed into the prediction model, with an AUC of 0.778(95% CI: 0.676-0.880)and χ2=3.72 and P=0.882>0.05 from the H-L test, consistent with the results of the training set. Conclusions:The model has some predictive value for acute kidney injury in elderly patients with sepsis.
