Medical ultrasound technology is widely used for diagnosis and therapy in clinical practice.Ultrasound probes,which are directly contact with patients,pose a potential risk of pathogen transmission.This expert consen-sus was developed by a multidisciplinary team based on international guidelines,standards in China,and the results of a national survey,aiming to reduce the risk of healthcare-associated infection through standardizing reprocessing of medical ultrasound probes,and formulating consensus recommendations with the Delphi method.The consensus clarifies the reprocessing principles for three types of ultrasound probes of different infection risks:external-use ul-trasound probes,interventional percutaneous ultrasound probes,and internal-use ultrasound probes,puts forward systematic suggestions on the reprocessing standards and disinfection levels of ultrasound probe isolation covers and coupling agents,the reprocessing procedures and methods of ultrasound probes,as well as architectural layout and management of reprocessing,so as to provide a scientific prevention and control framework for ensuring ultrasound diagnosis and therapy safety.

With the development of thyroid pathology in the past decade, thyroid pathological diagnosis has entered the era of molecular pathology. As the most influential academic journal in the field of pathology in China, Chinese Journal of Pathology has published nearly one hundred articles related to thyroid diseases in the past decade. These results have made a great difference to the scientific research and clinicopathological diagnosis of thyroid diseases in China, and have also provided Chinese data for the pathological communication of thyroid diseases internationally. Pathologists should make full use of thyroid cytology and histopathology, combined with molecular testing and digital intelligence technology, to play a core guiding role in the multidisciplinary precise diagnosis and treatment of thyroid diseases.

Objective To investigate the characteristics of traditional Chinese medicine(TCM)syndrome elements and the distribution patterns of TCM syndromes in senile osteoporosis(SOP),providing a reference for TCM treatment of SOP.Methods A cross-sectional study was conducted on 200 SOP patients aged over 70 years treated at Wuxi Huishan Chinese Medicine Hospital from January 2022 to June 2023.General information and TCM diagnostic data were collected.The syndrome element differentiation scoring method was employed for analysis.Results(1)Among the 200 SOP patients,the most prevalent disease-location syndrome element was kidney(61.50％),followed by liver(48.50％),bones and tendons(45.50％),spleen(37.00％),meridians(25.50％),heart(12.50％),and lung(10.50％).Statistical analysis showed significantly higher syndrome element scores for kidney,liver,bones and tendons,spleen,and meridians compared to heart and lung(P＜0.01).(2)Regarding disease-nature syndrome elements,deficiency-type elements predominated,with yang deficiency(52.50％)being most common,followed by blood deficiency(46.00％),essence depletion(45.50％),qi deficiency(45.50％),yin deficiency(37.00％),unconsolidation(25.50％),and qi sinking(15.50％).Yang deficiency,blood deficiency,essence depletion,qi deficiency,and yin deficiency scores were significantly higher than those of insecurity and qi sinking,the difference being statistically significant(P＜0.01).Among excess-type elements,cold(47.00％)was most prevalent,followed by blood stasis(45.00％),qi stagnation(43.50％),dampness(34.50％),phlegm(27.50％),and heat(25.00％).Cold and blood stasis scores were significantly higher than phlegm,while cold,blood stasis,qi stagnation,dampness,and phlegm scores were significantly higher than heat,the difference being statistically significant(P＜0.05).(3)Eighteen TCM syndrome patterns were identified.Spleen-kidney yang deficiency(40.00％)was most frequent,followed by liver blood deficiency(37.50％),kidney essence insufficiency(35.00％),qi stagnation and blood stasis(31.00％),cold congelation and obstruction(25.50％),phlegm-damp obstruction(27.50％),and qi-yin deficiency with qi insecurity(11.00％).Based on syndrome element scores,the primary syndromes were defiined as spleen-kidney yang deficiency(35.60％),liver blood deficiency(25.13％),kidney essence insufficiency(18.32％),and qi stagnation and blood stasis(13.09％),etc.Conclusion The characteristic TCM syndrome elements of SOP patients involve qi-blood-yin-yang deficiency of kidney,spleen,and liver,combined with cold congelation,blood stasis,and qi stagnation.The main TCM syndromes are spleen-kidney yang deficiency,liver blood deficiency,kidney essence insufficiency,and qi stagnation with blood stasis.

The STAR tool was used to evaluate and analyze the science, transparency, and applicability of Chinese pathology guidelines and consensus published in medical journals in 2022. There were a total of 18 pathology guidelines and consensuses published in 2022, including 1 guideline and 17 consensuses. The results showed that the guideline score was 21.83 points, lower than the overall guideline average (43.4 points). Consensus ratings scored an average of 27.87 points, on par with the overall consensus level (28.3 points). Areas that scored above the overall level were "conflict of interest" and "working groups", while areas that scored below the overall level were "proposals", "funding", "evidence", "consensus approaches" and "accessibility". To sum up, the formulation of pathology guidelines and consensuses in 2022 is not standardized, and the evidence retrieval process, evidence evaluation methods and grading criteria for recommendations on clinical issues are not provided in the formulation process; the process and method for reaching consensus are not provided, the plan is lacking, and registration is not carried out. It is therefore suggested that guidelines/consensus makers in the field of pathology should attach importance to evidence-based medical evidence, strictly follow guideline formulation methods and processes, further improve the scientific, applicable and transparent guidelines/consensuses in the field, and better provide support for clinicians and patients.

【Objective】 To establish a risk model for predicting spontaneous rupture bleeding of renal angiomyolipoma (RAML) in order to better assess and deal with the risk. 【Methods】 The information of 436 RAML patients diagnosed during Jan.2018 and Dec.2022 was retrospectively analyzed.According to the inclusion and exclusion criteria, 216 patients were included and divided into the rupture bleeding group (n=35) and non-rupture bleeding group (n=181).The factors influencing spontaneous rupture bleeding were identified using univariate and multivariate analysis, and a nomogram was constructed accordingly with R language.The nomogram was evaluated using Calibration curve and area under the receiver operator characteristic curve (AUC). 【Results】 It was found that clinical manifestations, tumor diameter, tumor convexity, tumor blood supply, and tuberous sclerosis complex (TSC) were significantly correlated with rupture bleeding.The Calibration curve fitted well with the nomogram.The AUC was 0.956 (95%CI: 0.856-0.943), indicating that the nomogram had good statistical performance. 【Conclusion】 The model can effectively predict the risk of spontaneous rupture bleeding of renal angiomyolipoma.

Objective:To investigate the relationship between micropapillary patten, cribriform pattern and retraction clefting of HPV associated endocervical adenocarcinoma and Silva classification and prognosis; and to validate the application and clinical significance of Silva system in endocervical adenocarcinoma.Methods:Cases of endocervical adenocarcinoma from January 2009 to November 2017 were selected from the Second Hospital of Jilin University and followed up. The morphologic characteristics of Silva classification, micropapillary patten, cribriform pattern and retraction clefting were observed and recorded. Inferential analysis was performed to compare clinicopathological variables data between pattern subgroups.Results:The study included 120 patients (ranging from 26 to 73 years) with an average age of (48.0±9.1)years. Silva A, B and C accounted for 9.2% (11/120), 18.3% (22/120) and 72.5% (87/120), respectively. Cases with micropapillary pattern accounted for 25.8%(31/120), of which six cases were Silva B and 25 cases were Silva C. Cases with cribriform pattern accounted for 53.3%(64/120), including three cases of Silva A, 17 cases of Silva B and 44 cases of Silva C. Retraction clefting occurred in 28.3%(34/120) cases, all were Silva C. The three morphologic features were associated with lymph node metastasis ( P<0.05). Univariate analysis showed that micropapillary pattern was related to prognosis of endocervical carcinoma ( P<0.05), while cribriform pattern, retraction clefting and Silva classification showed no correlation with overall survival and disease-free survival. Conclusions:The suggestion is revising the Silva C criteria by adding papillary patten and retraction clefting as factors and expanding the Silva pattern system to include more histologic variants. The Silva system is helpful to select appropriate operation before surgery, but its prognostic value requires further evaluation.
