Objective This study aimed to analyze the impact of genetic factors on the clinical presentation of tic disorder and investigate the pathogenesis of tic disorder considering different sources of genetic influence and generations,along with the distribution characteristics of evidence from Chinese medicine.Methods Inclusion of 474 cases of tic disorder was assembled(from October,2020 to October,2023),and clinical data on the children,including gender,age of onset,disease duration,initial symptoms,severity,comorbidities,and family history,and TCM patterns were collected.Firstly,the children were divided into genetic and nongenetic groups based on family history,and their clinical manifestations were observed.Secondly,the age of peak incidence of tic disorder in China(6 or 9 years)was used as the age segmentation point to explore the influence of heredity on clinical manifestations at different ages and the distribution of TCM patterns.Finally,children with genetically-related tic disorder were selected as probands to carry out family studies.The morbidity of the first-degree,second-degree and third-degree relatives of the probands were investigated to analyze the morbidity characteristics and distribution of TCM patterns of children with tic disorder under different genetic types.Results Out of 474 children,226 cases(47.7％)belonged to the genetic group,and 248 cases(52.3％)to the nongenetic group.Compared with the non-genetic group,the genetic group had a younger age of onset(P=0.013),a longer duration of illness(P=0.011),a higher degree of severity(P＜0.01),and more comorbid conditions(P=0.016).Children in the genetic group with an age of onset under 6 years accounted for a larger proportion of the liver-hyperactive and wind-driven pattern(26.5％)and a smaller proportion of the qi depression transforming into fire pattern(17.1％),which were significantly different from those in the non-genetic group(P=0.016).In the genetic group,146 cases(64.6％)were inherited from the father,80 cases(35.4％)from the mother,and there was no significant difference in the developmental characteristics of children with tic disorder from different sources of genetic influence.Furthermore,183 cases(81.0％)were inherited from the parent-child generation,26 cases(11.5％)from the second generation,and 17 cases(7.5％)from the third generation;the difference in initial symptoms between different genetic generations was statistically significant(P=0.042).Conclusion Children with genetically related tic disorder have a younger age of onset,their condition is more severe,and they are more likely to be comorbid with other psychiatric disorders.The variation in the distribution of Chinese medicine patterns among children with tic disorder of different ages of onset.

ObjectiveTo explore the suitability of four qualitative research methods in the development of TCM scale. MethodsTaking the development of "Seven Emotions Scale" as an example， we conducted semi-structured interviews with 31 patients of emotional disorders and 10 healthy people by objective sampling， and collected psychological feelings and emotional cognition data related to seven emotions according to the interview outline. Two qualitative methods， descriptive qualitative research and descriptive phenomenology， were used to analyze the data and construct the item library of the scale. The conceptual framework of the scale was constructed by using commonly used grounded theory and frame analysis. ResultsDuring data analysis， it is found that the themes extracted from descriptive phenomenology were not easily understood by the interviewees， and it is difficult for the researchers to truly achieve the "suspension" required by phenomenology. Considering the feasibility and convenience of the researchers' actual operation， as well as whether the initial purpose of the scale research can be intuitively included in the interviewees' views and feelings， descriptive phenomenology is not suitable for the formation of scale items. Using descriptive qualitative research method to analyze the interview data of healthy people and patients with emotional disorders， 306 and 476 scale items were obtained respectively. Through grounded theory， five selective codes were obtained： physical symptoms， external manifestations， psychological feelings， behaviors and emotional control. Using frame analysis， four themes including physical symptoms， psychological feelings， behavior and emotional cognition were constructed. Both methods can be used to construct the conceptual frame of scale， but the framework analysis is more convenient and can better ensure the transparency of the research. ConclusionDescriptive qualitative research methods can be used to form the item library of TCM scales. Framework analysis is more suitable for the construction of the conceptual framework of the scale than grounded theory， while descriptive phenomenology is not suitable for the development of TCM scales.

Objective To analyze the clinical manifestations of delayed serological transfusion reactions(DSTR)after platelet transfusion in tumor patients,and to explore the transfusion strategy.Methods Clinical data and laboratory test re-sults of patients with positive antibody screening were analyzed after platelet transfusion in our hospital from January 1,2015 to June 30,2023,and the incidence rate,clinical characteristics and transfusion strategy of patients with DSTR were ana-lyzed.Results A total of 2 553 patients with 6 057 platelet transfusions were reviewed.Eight patients developed DSTR and received a total of 21 therapeutic amounts of platelets,and 5 patients were subsequently transfused with red blood cells.Rh system antibodies were detected in 7 cases(4 anti-E,1 anti-c/E,1 anti-C and 1 anti-c)and Kell system antibodies in 1 case.Conclusion Tumor patients may also develop DSTR after platelet transfusion.It is necessary to pay close attention to the antibody situation and perform matched transfusion when transfusing blood again.

Objective:To analyze the iodine nutrition status of children aged 8 to 10 years in Zhejiang Province from 2016 to 2021.Methods:A multi-stage stratified sampling method was used to select non-residential children aged 8 to 10 years from 90 counties in Zhejiang Province. A total of 114 103 children were included in the study from 2016 to 2021. Direct titration method and arsenic-cerium catalytic spectrophotometry were used to detect salt iodine content and urinary iodine level, respectively, to evaluate the iodine nutritional status of children. Ultrasound was used to detect thyroid volume and analyze the current prevalence of goiter in school-age children.Results:The age of 114 103 children was (9.04 ± 0.81) years old, with 50.0% of (57 083) boys. The median of iodine content M ( Q1, Q3) in children's household salt was 23.00 (19.80, 25.20) mg/kg, including 17 242 non-iodized salt, 6 173 unqualified iodized salt, and 90 688 qualified iodized salt. The coverage rate of iodized salt was 84.89%, and the coverage rate of qualified iodized salt was 79.48%. The proportion of non-iodized salt increased from 11.85% in 2016 to 16.04% in 2021 ( χ 2trend=111.427, P<0.001). The median of urinary iodine concentration M ( Q1, Q3) in children was 182.50 (121.00, 261.00) μg/L, among which the proportions of iodine deficiency, iodine suitability, iodine over suitability, and iodine excess were 17.25% (19 686 cases), 39.21% (44 745 cases), 26.85% (30 638 cases), and 16.68% (19 034 cases), respectively. The median of urinary iodine concentration in children in inland areas [ M ( Q1, Q3): 190.90 (128.80, 269.00) μg/L] was significantly higher than that in children in coastal areas [ M ( Q1, Q3): 173.00 (113.00, 250.30) μg/L] ( P<0.001). From 2016 to 2021, a total of 39 134 ultrasound examinations were conducted, and 1 229 cases of thyroid enlargement were detected. The goiter rate was 3.14% (95% CI: 2.97%-3.32%). The incidence of goiter in children in coastal areas [3.45% (95% CI: 3.19%-3.72%), 641/18 604] was higher than that in children in inland areas [2.86% (95% CI: 2.64%-3.10%), 588/20 530] ( P=0.001). Conclusion:From 2016 to 2021, the iodine nutrition level of children aged 8-10 years in Zhejiang Province is generally suitable, and the rate of goiter in children meets the limit of iodine deficiency disease elimination standards.

Background::Cardiovascular disease (CVD) has emerged as the leading cause of death from prostate cancer (PCa) in recent decades, bringing a great disease burden worldwide. Men with preexisting CVD have an increased risk for major adverse cardiovascular events when treated with androgen deprivation therapy (ADT). The present study aimed to explore the prevalence and risk evaluation of CVD among people with newly diagnosed PCa in China.Methods::Clinical data of newly diagnosed PCa patients were retrospectively collected from 34 centers in China from 2010 to 2022 through convenience sampling. CVD was defined as myocardial infarction, arrhythmia, heart failure, stroke, ischemic heart disease, and others. CVD risk was estimated by calculating Framingham risk scores (FRS). Patients were accordingly divided into low-, medium-, and high-risk groups. χ2 or Fisher’s exact test was used for comparison of categorical variables. Results::A total of 4253 patients were enrolled in the present study. A total of 27.0% (1147/4253) of patients had comorbid PCa and CVD, and 7.2% (307/4253) had two or more CVDs. The enrolled population was distributed in six regions of China, and approximately 71.0% (3019/4253) of patients lived in urban areas. With imaging and pathological evaluation, most PCa patients were diagnosed at an advanced stage, with 20.5% (871/4253) locally progressing and 20.5% (871/4253) showing metastasis. Most of them initiated prostatectomy (46.6%, 1983/4253) or regimens involving ADT therapy (45.7%, 1944/4253) for prostate cancer. In the present PCa cohort, 43.1% (1832/4253) of patients had hypertension, and half of them had poorly controlled blood pressure. With FRS stratification, as expected, a higher risk of CVD was related to aging and metabolic disturbance. However, we also found that patients with treatment involving ADT presented an originally higher risk of CVD than those without ADT. This was in accordance with clinical practice, i.e., aged patients or patients at advanced oncological stages were inclined to accept systematic integrative therapy instead of surgery. Among patients who underwent medical castration, only 4.0% (45/1118) received gonadotropin releasing hormone antagonists, in stark contrast to the grim situation of CVD prevalence and risk.Conclusions::PCa patients in China are diagnosed at an advanced stage. A heavy CVD burden was present at the initiation of treatment. Patients who accepted ADT-related therapy showed an original higher risk of CVD, but the awareness of cardiovascular protection was far from sufficient.

Objective:To investigate the clinicopathological characteristics of rashes in monkeypox patients through a series of skin biopsies, and examine their pathological features and the most effective tests.Methods:Patients with monkeypox virus infection admitted to Beijing Ditan Hospital from June to August 2023 were identified. Among them, 24 patients underwent skin biopsies for clinical pathological study that were included in this study. Clinical information, rash pictures, and nucleic acid test results were analyzed using histopathology, immunohistochemistry, RNAscope ? hybridization and electron microscopy. Results:All 24 patients were male, including 14 patients with concurrent human immunodeficiency virus infection. Their average age was (32.3±5.4) years. The nucleic acid test confirmed monkeypox virus infection. The clinical feature of monkeypox rashes was solitary rather than clustered distribution, with rashes occurring in similar phase, distinguishing it from herpesvirus. The rashes in these patients were mostly scattered, with an average of (13.0±11.8) rashes, and most commonly present in the perineum, face, limbs, and trunk. The three main pathological features of these rashes were ballooning degeneration of the epidermal spinous cell layer, the characteristic intra-cytoplasmic Guarnieri′s bodies and significant infiltration of inflammatory cells in whole dermal layer. Immunohistochemistry, RNAscope ? hybridization, and electron microscopy can all effectively detect the monkeypox virus. Electron microscopy showed viral replication in various types of skin cells. Conclusions:The study describes the pathological features of monkeypox virus rashes. Pathological examination of skin biopsy samples is helpful to diagnose these rashes. The study suggests that the monkeypox virus has a unique epitheliotropic affinity and can infect various types of cells in the skin.

Objective To study the identification methods and traits of the Chinese medicinal materials Inonotus obliquus.Methods Samples were collected from the origin of northeast China,and source identification,molecular biology identification,trait identification,microscopic identification and HPLC assay were used to study the Inonotus obliquus,its non-pure fungous part,and counterfeit.Results Inonotus obliquus had a nodular shape,the microstructure was closely interconnected with mycelia,and the medicinal part was the sclerotium,not the"fruiting body"as stipulated in the current standards of traditional Chinese medicinal materials.Occasionally,a very small amount of tubule and subiculum could be seen in Inonotus obliquus.Tubule hole shape was circular,with a diameter of 130-190 μm,and ruptured.The pipe wall structure was special,which was composed of longitudinal arranged small compartment with diameter of 2-5-8 μm.Non-pure fungous part was the decayed host xylem infiltrated by mycelia.The contents of trametenolic acid and ergosterol in this part were significantly lower than the pure sclerotium(P<0.05).The microstructure and HPLC fingerprints of Inonotus obliquus and the counterfeit burl were clearly distinguishable from each other.Conclusion The method used is able to identify the authenticity of Inonotus obliquus and the quality of the medicinal materials.

OBJECTIVE To establish thin-layer chromatography （TLC） identification method and high-performance liquid chromatography （HPLC） fingerprint of Inonotus obliquus， and to evaluate the quality of I. obliquus by chemical pattern recognition. METHODS TLC method was used to identify trametenolic acid and inotodiol in I. obliquus qualitatively. HPLC fingerprint of I. obliquus was established； Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine （2012 edition） was used to determine the common peaks and evaluate the similarity； chemical pattern recognition analysis [cluster analysis， principal component analysis and orthogonal partial least squares-discriminant analysis （OPLS-DA）] of 22 batches of I. obliquus was performed with SPSS 23.0 software and SIMCA14.1 software. RESULTS In the TLC， the same color spots were found at the same position in the chromatograms of test sample and substance control. A total of 10 common peaks were marked in the HPLC fingerprints of 22 batches of I. obliquus， with similarities of 0.942-0.995. No. 3 peak was identified as trametenolic acid， No.4 peak as inotodiol， No. 9 peak as ergosterol and No. 10 peak as lanosterol. Results of cluster analysis showed that S1-S15， S19， S21 and S22 could be clustered into the first category， and S16-S18 and S20 were clustered into the second category. Results of principal component analysis showed that top 4 samples in the list of comprehensive score were S17， S18， S16 and S20. Results of OPLS-DA showed that three marking components that may affect the quality of I. obliquus were screened according to the standard of VIP＞1， i.e. No. 4 peak （inotodiol， VIP value of 1.86）， No. 3 peak （trametenolic acid， VIP value of 1.62） and No. 7 peak （VIP value of 1.27）. CONCLUSIONS This study establishes TLC method and HPLC fingerprint of I. obliquus successfully， which can provide reference for the quality control of I.obliquus by combining with chemical pattern recognition.

【Objective】 To evaluate the detection and distribution characteristics of anti-P1 in tumor patients, so as to aid in blood screening and transfusion safety. 【Methods】 The clinical data of 112 658 tumor patients who underwent blood preparation and transfusion in our hospital from January 2014 to December 2021 were retrospectively analyzed, and column agglutination technique was used to perform transfusion compatibility test. 【Results】 A total of 1 079 (0.96%, 1 079/112 658) cases were detected with unexpected antibodies, of which 71 (6.58%, 71/1 079) were identified as anti-P1. In anti-P1 cases, 59.15% (42/71) were males; 60.56% had no pregnancy history (P<0.01); 29.58% (21/71), 52.11%(37/71), 12.68%(9/71) and 5.63%(4/71) of anti-P1 patients were with type A, B, O and AB, respectively. 57 cases of anti-P1 patients (80.28%) had difficulty in ABO blood group identification. The incidence of interfering in patients with type B was higher than that of other blood types (P<0.05), as the frequency of w+ in reverse blood typing was higher than other reactive patterns (P<0.05). The incidence of gastric tumor and brain space-occupying lesion in patients with anti-P1 was higher than that in patients with other alloantibodies, while the incidence of gynecological tumors was lower (P<0.05). 【Conclusion】 Anti-P1 affects the ABO blood group identification of tumor patients, and most of them had difficulty in ABO blood group identification. Compared with patients with other alloantibodies, patients with anti-P1 are more likely to be male and suffer from gastric and brain tumors, but less likely from gynecological tumors.
