Objective: To characterize the serological profile, RHD genetic spectrum, and their frequencies among pregnant women preliminary screened as RhD-negative and weak positive in Qingdao and surrounding areas, and correlate these findings with unexpected antibody detection results, thereby providing testing recommendations and suggestions for such individuals. Methods: Blood samples of pregnant women who were initially identified as RhD negative and weak positive in hospitals in Qingdao and surrounding areas over the past five years were collected. Different cloned IgG anti-D antibodies were used for RhD negative confirmation experiments. RHD genotyping was performed by combining PCR-SSP and Sanger sequencing. Unexpected antibody screening and identification were carried out using test tube method and microcolumn gel card. The immunologic status of newborns delivered by anti-D pregnant women was also tracked. Results: A total of 602 blood samples were collected from pregnant women initially identified as RhD-negative and weak positive. Among them, 569 (94.5%) were confirmed as RhD-negative in the RhD confirmation test, and 33 (5.5%) were D variant phenotype. Except for 4 cases where no definite mutations were found, gene analysis revealed 474 (78.7%) D-negative cases with 5 genotypes (RHD 01N.01, RHD 01N.03, RHD 01N.16, RHD 01N.05, and 1 new allele), 90 (15.0%) Del cases with 2 genotypes (RHD 01EL.01, and RHD 01EL.18), 23 (3.8%) weak D cases with 2 genotypes (RHD 15 and 1 new allele), and 11 (1.8%) partial D cases with 2 genotypes (RHD 06.03.01 and RHD 05.04). Anti-D and complex antibodies containing anti-D were detected in 96 RhD-negative and partial D pregnant women (15.9%). After injection of anti-D immunoglobulin, One O-type RhD-negative pregnant woman delivered a newborn with hyperbilirubinemia. The newborn was typed to be B Del, and anti-D was detected in both serum and eluate. Conclusion: The serological profiles, RHD gene types and frequencies among RhD negative pregnant women in Qingdao and surrounding areas are basically consistent with domestic published data. Pregnancy can stimulate anti-D production in D-negative and partial D individuals. However, anti-D antibody has not been detected in Del type pregnant women. Since anti-D immunoglobulin can binds to Del type red blood cells, its administration is not recommended for Del type pregnant women.

This paper summarizes professor LI Guolie's clinical experience in treating orthostatic hypotension （OH） based on the theory of "raising the clear and directing the turbid downward". It is considered that the core pathogenesis of OH lies in the body's transition from a supine to an upright position， during which dysfunction of the middle jiao （焦） transformation and transportation， along with impaired pivot function， hinders the ascending of clear yang and the descending of turbid yin. Treatment should follow the general principle of "ascending the clear and directing the turbid downward"， placing emphasis on distinguishing the primary and secondary aspects. For cases where the clear yang fails to ascend， the self-formulated Li's Shengqing Jiangzhuo Decoction （李氏升清降浊汤）is used to supplement qi， raise the clear， and strengthen the middle jiao. For cases where the turbid yin fails to descend， the self-formulated Wuxiang Qingzhuo Beverage（五香清浊饮）with modifications is applied to resolve phlegm， eliminate stasis， harmonize the middle， and descend the turbid.

Atherosclerotic plaques arise within the vessels， yet their morphological evolution parallels that of carbuncles and abscesses. Drawing on the pathomechanism progression of carbuncles and abscesses， this paper proposes a dynamic pathogenesis model of "constraint-putrefaction-ulceration" for atherosclerotic plaques. The formation of atherosclerotic plaque begins with phlegm-turbidity obstruction and qi-blood stagnation （constraint stage）； prolonged constraint transforms into heat that scorches the vessels and forms plaques （putrefaction stage）； ultimately， toxin invades inward and ruptures the vessels， injuring the heart （ulceration stage）. Accordingly， staged differentiation and treatments are proposed. During the constraint stage， the focus is venting constraint and unblocking collaterals， clearing and relieving constraint-heat， for which Yue Jyu Pills （越鞠丸） and Danzhi Xiaoyao Powder （丹栀逍遥散） with modifications can be used. During the putrefaction stage， the method is clearing heat and dispelling abscesses， resolving stasis and dissipating knot， with modified Wuwei Xiaodu Beverage （五味消毒饮） and Xuefu Zhuyu Decoction （血府逐瘀汤）. During the ulceration stage， it is suggested to expell toxin and stasis， benefit qi and nourish yin using modified Gualou Xiebai Banxia Decoction （瓜蒌薤白半夏汤） and Sheng Mai Powder （生脉散）. This framework offers new perspectives for the differentiation and treatment of atherosclerotic plaques in traditional Chinese medicine.

Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality, characterized by poor prognosis due to its high proliferative and invasive potential. Tumor metabolic reprogramming, particularly involving glucose metabolism, is essential for tumor survival. This study investigates the role of the Hippo pathway effector transcriptional co-activator with PDZ-binding motif (TAZ) in regulating gluconeogenesis and promoting tumorigenesis in HCC. Methods: TAZ expression in HCC was analyzed using The Cancer Genome Atlas data and validated in clinical samples and cell lines. TAZ was overexpressed or silenced in HCC cell lines to evaluate its effects on cell proliferation, apoptosis, migration, and invasion. The expression and prognostic relevance of the gluconeogenesis-related genes phosphoenolpyruvate carboxykinase 1 (PCK1) and glucose-6-phosphatase (G6PC) were examined, along with their correlation with TAZ expression. Tumor growth was assessed in nude mice. Interactions between TAZ and the glucocorticoid receptor (GR) were investigated using co-immunoprecipitation, immunofluorescence, and chromatin immunoprecipitation assays. Results: TAZ was significantly upregulated in HCC tissues and cell lines. TAZ overexpression enhanced proliferation, reduced apoptosis, and promoted migration and invasion. In contrast, PCK1 and G6PC were downregulated in HCC and showed a negative correlation with TAZ expression. Conclusion TAZ modulates gluconeogenesis and accelerates tumor growth, whereas its knockdown attenuates tumor progression. TAZ interacts with GR, suppressing its transcriptional activity on gluconeogenic gene promoters.

Based on the physiological characteristics of children and the theory of the "five spirit-associated zang （脏） organs"， this paper proposes that the core pathogenesis of autism spectrum disorder （ASD） in children is the dysfunction of mental activities caused by impaired qi circulation of the five zang organs. Therefore， the therapeutic principle is to regulate qi of the five zang organs and restore normal mental function. Treatment is administered based on syndrome differentiation according to the five zang organs， including heart， spleen， kidney， liver and lung. Accordingly， self-made Qingshen Yangxin Decoction （清神养心汤） is prescribed to invigorate the heart and regulate spirit， Shunzhi Daotan Decoction （顺志导痰汤） to awaken spleen and regulate spirit， Zishen Shenjiao Decoction （滋肾神交汤） to nourish kidney and regulate spirit， Anhun Wendan Decoction （安魂温胆汤） to soothe liver and regulate spirit， and Qingpo Decoction （清魄汤） to diffuse lung and regulate spirit. This approach aims to provide a theoretical and clinical reference for the treatment of childhood ASD in traditional Chinese medicine.

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 compare the diagnostic efficacy of the added 99Tc m-methoxyisobutylisonitrile (MIBI) SPECT/CT imaging (tomography imaging) after early or delayed planar imaging in different types of hyperparathyroidism, and to seek for the optimal timing of preoperative imaging. Methods:A total of 339 patients (148 males, 191 females, age (52±13) years) with primary or secondary hyperparathyroidism and pathological results from January 2016 to June 2024 in the Second Affiliated Hospital of Soochow University were retrospectively analyzed. The patients were divided into primary early tomography imaging group ( n=63) and delayed tomography imaging group ( n=47), secondary early tomography imaging group ( n=89) and delayed tomography imaging group ( n=140). χ2 test was used to compare the diagnostic efficacies of early and delayed tomography imaging. Results:The difference of accuracy between primary delayed (98.40%(185/188)) and early tomography imaging (94.84%(239/252)) was statistically significant ( χ2=3.90, P=0.048). There were significant differences in sensitivity (77.29%(405/524) and 85.40%(275/322)), accuracy (75.89%(425/560) and 83.99%(299/356)) and negative predictive value (14.39%(20/139) and 33.80%(24/71)) between secondary delayed and early tomography imaging ( χ2 values: 8.33, 8.61, 10.70, all P<0.01). Conclusion:The optimal timing of preoperative 99Tc m-MIBI SPECT/CT imaging for primary and secondary hyperparathyroidism is after delayed planar imaging and after early planar imaging respectively.

OBJECTIVE To explore the diagnostic value of combined detection of microRNA(miRNA)and alpha-fetoprotein(AFP),protein induced by vitamin K absence or antagonist-Ⅱ(PIVKA-Ⅱ)in ascites and serum ex-tracellular vesicles(EVs)for hepatitis B virus(HBV)-related primary hepatocellular carcinoma(HCC).METHODS From Nov.2023 to Nov.2024,41 patients with liver cancer and 26 patients with liver cirrhosis who underwent ascites placement or ascites concentration and reinfusion procedures at the Fifth Medical Center of Chi-nese PLA General Hospital were selected as study subjects.Ascites and serum samples were collected.Real-time quantitative reverse transcription polymerase chain reaction(qRT-PCR)was used to detect the expression levels of miR-21,miR-125a,miR-150 and miR-200a in EVs.Chemiluminescence was used to measure the levels of AFP and PIVKA-Ⅱ in ascites,serum and EVs from ascites and serum.An artificial neural network was utilized to con-struct a combined diagnostic model of serum and ascites markers.RESULTS The area under the curve(AUC)for distinguishing HCC from liver cirrhosis using a combination of serum and other indicators was 0.933.The AUC for distinguishing HCC from liver cirrhosis using a combination of ascites and other indicators was 0.912.By screening all detected indicators using an artificial neural network and incorporating indicators with a relative im-portance＞0.5 into the diagnostic model,the model included four indicators:ascites AFP,ascites EVs miR-21,ascites EVs miR-200a and serum EVs miR-200a.This model had a sensitivity of 80.77％,a specificity of 87.80％and an AUC of 0.960 for distinguishing HCC from liver cirrhosis patients.CONCLUSION The combined diagnos-tic markers of miRNA,AFP and PIVKA-Ⅱ in ascites and serum-derived EVs have good application value in the diagnosis of HCC.
