Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

Objective:To investigate the effects of influenza A virus(IAV)on macrophages based on expression of cytokines mediated by Janus kinase/signal transducer and activator of transcription(JAK/STAT)pathway,and to further explore the intervention effects of Ma Xing Shigan decoction drug containing serum.Methods:RAW264.7 was divided into control group,JAK/STAT signal pathway activator group,inhibitor group,model group,oseltamivir group,antiviral granule group and Ma Xing Shigan decoction group.Cell samples were collected after the intervention of IAV and subsequent treating of drug-containing serum for 24 and 48 hours.Secretion levels of IL-1β and CXCL2 in supernatant were detected by ELISA.mRNA expression levels of influenza virus Nuclear Pro-tein(NP),JAK1/2 and STAT1 of cells were detected by RT-qPCR.Protein expression levels of JAK1/2 and STAT1 were detected by Western blot,and protein expression levels of p-STAT1 was detected by immunofluorescence.Correlation between protein expression levels of p-STAT1 and secretion of IL-1β and CXCL2 were evaluated by Pearson correlation analysis.Results:Secretion levels of IL-1β and CXCL2,mRNA expression levels of NP,JAK1/2,STAT1,protein levels of JAK1/2,STAT1 and p-STAT1 were increased,and protein levels of p-STAT1 was positively correlated with the secretion of IL-1β and CXCL2.Ma Xing Shigan decoction could down-regulate secretions of IL-1β and CXCL2,mRNA expression levels of NP,JAK1/2 and STAT1,protein expression levels of JAK1,JAK2,STAT1 and p-STAT1.Conclusion:Activation of JAK1/2-STAT1 signal pathway and imbalance of inflammatory factors may be one of the molecular mechanisms of immunopathological damage of macrophages induced by IAV.Ma Xing Shigan decoction may alle-viate pathogenic effects of IAV by regulating this signal pathway.

Objective To analyze the development trajectory and predictors of endocrine therapy associated arthralgia in breast cancer patients.Methods From January 2022 to July 2022,breast cancer patients in the breast medicine department or outpatients of a tertiary cancer hospital in Hunan Province were selected as respondents using a convenience sampling method.A baseline survey was conducted using the General Information Questionnaire,the Symptom Assessment Scale for Patients Treated with Endocrine Therapy for Breast Cancer,and the Self-Rating Anxiety Scale within 1 week prior to patient treatment.The Symptom Assessment Scale for Patients Treated with Endocrine Therapy for Breast Cancer was used to assess patients'arthralgia levels at 3,6,and 9 months after treatment,and data were analyzed using growth mixed model,univariate analysis of variance,and multiple logistic regression.Results A total of 418 breast cancer patients completed the follow-up,with 235 cases(56.22%)developing arthralgia.3 potential categories of arthralgia develop-ment trajectories were identified:high level-slowly increasing group(11.48%),low level-slowly increasing group(44.74%),and asymptomatic group(43.78%).The results of multifactorial analysis showed that anxiety,history of bone and joint disease,sleep duration,place of residence,monthly household income,and frequency of exercise were predictors of potential categories for the development of trajectory of arthralgia levels associated with endocrine therapy in breast cancer patients(P<0.05).Conclusion Arthralgia levels associated with endocrine therapy in breast cancer patients exhibit different trajec-tories,and clinical staff should emphasize the assessment and intervention of pain levels in patients with the anxiety,a history of bone and joint disease,poor sleep,poor finances,living in urban areas,and low frequency of exercise.

Objective:To investigate the incidence of osteoporosis in elderly women after radical mastectomy and analyze its influencing factors, so as to provide guidance for the prevention of this disease.Methods:Clinical data of 103 elderly women treated in our hospital after radical mastectomy from Jan. 2020 to Jan. 2021 were collected and separated into osteoporosis group ( n=58) and non-osteoporosis group ( n=45) according to whether osteoporosis occurred. The factors affecting the occurrence of osteoporosis and the relationship between endocrine hormones and bone metabolism were analyzed, and prevention strategies were formulated. Results:(1) The proportion of patients with osteoporosis >70 years old, menopausal years ≥5 years, body mass index <25kg/m 2, endocrine therapy in osteoporosis group was higher than that in non-osteoporosis group ( χ2 =8.68, 18.54, 9.72, 16.98, 36.51, P=0.003, <0.001, 0.002, <0.001, <0.001) ; (2) The level of estradiol in the osteoporosis group was lower than the other group ( t value =20.53, P<0.05), and the level of follicle-stimulating hormone was higher ( t value=19.14, P<0.05) ; (3) Old age, endocrine therapy, low bone mineral density and low estradiol level were the risk factors for osteoporosis after radical mastectomy ( P<0.05) ; (4) Pearson correlation analysis showed that bone mineral density in patients with osteoporosis after radical mastectomy was positively correlated with estradiol and testosterone levels ( r=0.352, 0.316, P<0.05), and negatively correlated with follicle-stimulating hormone levels ( r=-0.334, P<0.05) . Conclusions:Osteoporosis in elderly women with radical mastectomy is affected by age, endocrine therapy, bone mineral density and estradiol, and there is a correlation between hormone levels and bone mineral density. Clinical prevention and treatment measures should be implemented in the direction of monitoring bone mineral density, physical exercise, safe drug use, and prevention of falling.

On the basis of the clinical characteristics of atherosclerosis(AS)in traditional Chinese medicine(TCM)and Western medicine,this paper analyzes common animal models of AS.The coincidence of clinical characteristics of the models was scored in the hope of providing new ideas and a reference for those studying AS.This paper reviews the varieties,modeling method,modeling principles,and characteristics of common animal models of AS.Moreover,similarities among common animal models,in terms of their clinical diagnostic criteria and symptom characteristics,were assessed.High-fat feeding type,mechanical injury combined with high-fat feeding type,genetic engineering combined with high-fat feeding type,chemical induction combined with high-fat feeding type,and combined Chinese clinical syndrome and Western disease AS models are widely established.Comparative analysis showed that balloon injury combined with high fat feeding type,ApoE receptor-knockout mouse combined with high-fat diet type,and phlegm and blood stasis type models of disease and symptom combinations showed a comparatively high level of clinical agreement between Chinese and Western medicine.Presently,most animal models of AS have a high degree of relevance to Western medicine,and the evaluation criteria used for the models are predominately from a Western medicine perspective.Models that combine disease and syndrome are lacking,hindering the development of wholism concepts and treatment through the differentiation of syndromes used in TCM.Therefore,establishing an animal model with a high degree of accuracy and coincidence between TCM and Western perspectives that combines the disease and its TCM symptoms is a top priority for studying the prevention and treatment of AS.

Objective To explore the risk factors for prolonged stay of menopausal female patients in intensive care unit(ICU)and construct a predictive model.Methods A total of 260 menopausal women hospitalized in ICU of Taizhou Central Hospital from June 2019 to December 2022 were selected as study subjects.According to the length of ICU stay,the patients were divided into extended group(≥5d,156 cases)and non-extended group(<5d,104 cases).The clinical data of patients were collected,and the factors affecting the length of stay in ICU patients were analyzed by multivariate Logistic regression.A nomogram prediction model was constructed,receiver operating characteristic curve was drawn,and the area under the curve(AUC)was calculated.Results The proportion of coma,invasive operation and using of broad spectrum antibiotic in extended group were significantly higher than those in non-extended group(P<0.05).The incidence of abnormal blood pressure,muscle/bone joint pain,abnormal heart rate,abnormal respiratory function and infection in extended group were significantly higher than those in non-extended group(P<0.05).Multivariate Logistic regression analysis showed that coma,invasive operation,using of broad spectrum antibiotic,abnormal blood pressure,abnormal heart rate,abnormal respiratory function and infection were the risk factors leading to prolonged ICU stay in menopausal women(P<0.05).The constructed nomogram model had a good fit(χ2=5.072,P=0.285).The AUC of patients with prolonged ICU stay predicted by nomogram model was 0.857(95%CI:0.778-0.937),the sensitivity was 78.16%,and the specificity was 83.67%.Conclusion Unstable conscious state,invasive operation,using of broad spectrum antibiotic,abnormal blood pressure,abnormal heart rate,abnormal respiratory function,and infection are all risk factors leading to prolonged ICU stay in menopausal women,which should be paid close attention to and timely targeted treatment.

Objective:To explore the effect of combining hand-brain perception training with hand-brain motor training based on mirror neuron theory on the recovery of upper limb function after a stroke.Methods:A group of 105 stroke survivors with upper limb dysfunction were randomly divided into a hand-brain perception (HP) group, a hand-brain motor (HM) group, and a combination (C) group, each of 35. In addition to conventional rehabilitation treatment (including exercise therapy, occupational therapy and physical factor therapy), the HP and HM groups were given hand-brain perception training and hand-brain motor training respectively, while group C was provided with both. Before the intervention and after 4 weeks, the upper limb motor functioning of all of the participants was assessed using the simplified version of the Fugl-Meyer upper limb motor function scale (FMA-UE). Sensory functioning was quantified using the tactile Semmes Weinstein monofilament examination (SWME), and the modified Barthel index (MBI) was used to quantify the participants′ ability in the activities of daily living.Results:After the intervention the average FMA-UE, MBI and SWME scores of all three groups had improved significantly, with group C′s average FMA-UE and MBI scores significantly better than the other two groups′ averages. The average SWME score of group C was then significantly better than that of group HM.Conclusions:Hand-brain perception combined with hand-brain motor training based on mirror neuron theory can further promote the recovery of upper limb sensory and motor functioning of stroke survivors., Such therapy is worthy of clinical promotion and application.
