Background::Endometriosis (EM) is a complex benign gynecological disease, but it has malignant biological behavior and can invade any part of the body. Clinical manifestations include pelvic pain, dysmenorrhea, infertility, pelvic nodules, and masses. Our previous study successfully detected circulating endometrial cells (CECs) in the peripheral blood of patients with EM. The purpose of this study is to overcome the limitation of cell size in the previous microfluidic chip method, to further accurately capture CECs, understand the characteristics of these cells, and explore the relationship between CECs and the clinical course characteristics of patients with EM.Methods::Human peripheral venous blood used to detect CECs and circulating vascular endothelial cells (CVECs) was taken from EM patients ( n = 34) hospitalized in the Peking University People’s Hospital. We used the subtraction enrichment and immunostaining fluorescence in situ hybridization (SE-iFISH) method to exclude the interference of red blood cells, white blood cells, and CVECs, so as to accurately capture the CECs in the peripheral blood of patients with EM. Then we clarified the size and ploidy number of chromosome 8 of CECs, and a second grouping of patients was performed based on clinical characteristics to determine the relationship between CECs and clinical course characteristics. Results::The peripheral blood of 34 EM patients and 12 non-EM patients was evaluated by SE-iFISH. Overall, 34 eligible EM patients were enrolled. The results showed that the detection rates of CECs were 58.8% in EM patients and 16.7% in the control group. However, after classification according to clinical characteristics, more CECs could be detected in the peripheral blood of patients with rapidly progressive EM, with a detection rate of 94.4% (17/18). In total, 63.5% (40/63) of these cells were small cells with diameters below 5 μm, and 44.4% (28/63) were aneuploid cells. No significant association was found between the number of CECs and EM stage.Conclusion::The number and characteristics of CECs are related to the clinical course characteristics of patients with EM, such as pain and changes in lesion size, and may be used as biomarkers for personalized treatment and management of EM in the future.

The awake prone position plays an important role in the treatment of hypoxemia and the improvement of respiratory distress symptoms in non-intubated patients. It is widely used in clinical practice because of its simple operation, safety, and economy. To enable clinical medical staff to scientifically and normatively implement prone position for awake patients without intubation, the committees of consensus formulation, guided by evidence-based methodology and Delphi method, conducted literature search, literature quality evaluation and evidence synthesis around seven topics, including indications and contraindications, evaluation, implementation, monitoring and safety management, termination time, complication prevention and health education of awake prone position. After two rounds of expert letter consultation, Expert consensus on implementation strategy of awake prone positioning for non-intubated patients in China (2023) was formulated, and provide guidance for clinical medical staff.

Chronic heart failure (CHF) is a severe public health problem with increasing morbidity and mortality, any treatment targeting a single session is insufficient to tackle this. CHF is characterized by reduced cardiac output resulting from neurohumoral dysregulation and cardiac remodeling, which might be related to oxidative stress, inflammation, endoplasmic reticulum stress, apoptosis, autophagy, mitochondrial function, and angiogenesis. These molecular mechanisms interact with each other through crosstalk. Historically, Chinese medicinal herbs have been widely applied in the treatment of CHF, and therapeutic effects of Chinese medicinal herbs and their ingredients have been scientifically confirmed over the past decades. Traditional Chinese medicine (TCM) with multiple components can confront the different pathogenesis of CHF through multiple targets. This review analyzes commonly used TCM patent drugs and TCM decoctions that are applicable to different stages of CHF based on clinical trials. Diverse bioactive ingredients in Chinese medicinal herbs have been found to treat CHF via multiple molecular mechanisms. This review comprehensively covers the key works on the effects and underlying mechanisms of TCM, herbal ingredients and synergistic effects of constituent compatibility in treating CHF, providing additional ideas to address this threat.

OBJECTIVE: To evaluate the efficacy and safety of glyceryl phenylbutyrate (GPB) therapy for patients with Ornithine transcarbamylase deficiency (OTCD). METHODS: Two children with OTCD were selected as the study subjects, and their clinical manifestations, blood ammonia, liver enzymes, growth and development information following the treatment with GPB were retrospectively analyzed. A literature review was also carried out by searching the PubMed database for studies on the GPB treatment for urea cycle disorders. RESULTS: With the GPB treatment, the blood ammonia and liver enzyme level in both patients have decreased to the normal range within 3 months. Motor development in child 2 has improved. No adverse reaction was noted, except for transient palmar greasy smell and loss of appetite in child 1. Analysis of the literature showed that patients had lower ammonia exposure, lower annual incidence of hyperammonemic crisis, more actual protein intake and fewer adverse events during GPB treatment. CONCLUSION GPB is safe and effective for the treatment of OTCD.

BACKGROUND: High-grade serous ovarian cancer (HGSOC) is the biggest cause of gynecological cancer-related mortality because of its extremely metastatic nature. This study aimed to explore and evaluate the characteristics of candidate factors associated with the metastasis and progression of HGSOC. METHODS: Transcriptomic data of HGSOC patients' samples collected from primary tumors and matched omental metastatic tumors were obtained from three independent studies in the National Center for Biotechnology Information (NCBI) Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were selected to evaluate the effects on the prognosis and progression of ovarian cancer using data from The Cancer Genome Atlas (TCGA) database. Hub genes' immune landscapes were estimated by the Tumor Immune Estimation Resource (TIMER) database. Finally, using 25 HGSOC patients' cancer tissues and 10 normal fallopian tube tissues, immunohistochemistry (IHC) was performed to quantify the expression levels of hub genes associated with International Federation of Gynecology and Obstetrics (FIGO) stages. RESULTS: Fourteen DEGs, ADIPOQ , ALPK2 , BARX1 , CD37 , CNR2 , COL5A3 , FABP4 , FAP , GPR68 , ITGBL1 , MOXD1 , PODNL1 , SFRP2 , and TRAF3IP3 , were upregulated in metastatic tumors in every database while CADPS , GATA4 , STAR , and TSPAN8 were downregulated. ALPK2 , FAP , SFRP2 , GATA4 , STAR , and TSPAN8 were selected as hub genes significantly associated with survival and recurrence. All hub genes were correlated with tumor microenvironment infiltration, especially cancer-associated fibroblasts and natural killer (NK) cells. Furthermore, the expression of FAP and SFRP2 was positively correlated with the International Federation of Gynecology and Obstetrics (FIGO) stage, and their increased protein expression levels in metastatic samples compared with primary tumor samples and normal tissues were confirmed by IHC ( P = 0.0002 and P = 0.0001, respectively). CONCLUSIONS This study describes screening for DEGs in HGSOC primary tumors and matched metastasis tumors using integrated bioinformatics analyses. We identified six hub genes that were correlated with the progression of HGSOC, particularly FAP and SFRP2 , which might provide effective targets to predict prognosis and provide novel insights into individual therapeutic strategies for HGSOC.

Objective:To explore the optimal local treatment pattern of supraclavicular lymph node in breast cancer patients with synchronous ipsilateral supraclavicular lymph node metastasis (sISLM).Methods:Clinical data of 128 breast cancer patients with sISLM admitted to the Fourth Hospital of Hebei Medical University from 2010 to 2015 were retrospectively analyzed. Among them, 68 cases were treated with supraclavicular lymph node dissection combined with radiotherapy, and 60 cases received radiotherapy alone. The locoregional recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), progression-free survival (PFS) and overall survival (OS) were statistically compared between two groups.Results:Univariate analysis demonstrated that the 5-year LRFS, DMFS, PFS and OS did not significantly differ between two groups (all P>0.05). Multivariate analysis revealed that the local treatment pattern of supraclavicular lymph node was an independent prognostic factor for the 5-year DMFS, PFS and OS (all P<0.05). Subgroup analysis showed that when radiotherapy alone was performed, the 5-year OS of patients in the supraclavicular region radiation dose of>50 Gy group were significantly better than that in the 50 Gy group ( P=0.047). When supraclavicular lymph node dissection combined with radiotherapy was delivered, if the number of dissection was less than 10, the 5-year LRFS, DMFS, PFS, OS of patients in the>50 Gy group were all better than those in the 50 Gy group numerically without statistical significance (all P>0.05). If the number of dissection was ≥10, the 5-year LRFS, DMFS, PFS, OS in the 50 Gy group were better than those in the>50 Gy group numerically, whereas significant difference was only found in the 5-year DMFS ( P=0.028). Conclusions:Supraclavicular lymph node dissection combined with radiotherapy may be the optimal local treatment pattern for supraclavicular lymph node. When radiotherapy alone is performed, a radiation boost to the supraclavicular region may improve OS. When supraclavicular lymph node dissection combined with radiotherapy is performed, if the degree of dissection is low, a radiation boost to the supraclavicular region may bring clinical benefits. However, if the degree of dissection is high, a radiation boost to the supraclavicular region may not bring significant clinical benefits.

OBJECTIVE: To explore the clinical characteristics and genetic basis for a pair of twins affected with hyaline fibromatosis syndrome (HFS). METHODS: Clinical data of the twins were retrospectively analyzed. High-throughput sequencing was carried out to detect potential pathogenic variants. CLUSTALX was employed to analyze cross-species conservation of the mutant amino acids. Impact of the mutations was predicted by using software including PolyPhen-2 and Mutation taster. RESULTS: The pair of twins have featured growth and intelligence retardation, and were found to carry compound heterozygous variants of the ANTXR2 gene including c.1214G>A and c.1074delT, among which c.1214G>A was unreported previously. Both variants were predicted to be pathogenic. In addition to growth and mental delay, the pair of twins also featured hyperplasia of the gum and soft tissue-like masses of the auricle. The younger brother had rupture of the auricle mass during follow-up. CONCLUSION The patients' condition can probably be attributed to the compound heterozygous variants of the ANTXR2 gene. Above finding has facilitated molecular diagnosis of the patients.

Objective:To study the incidence and risk factors of the corrected QT (QTc) prolongation in breast cancer patients treated with anthracyclines.Methods:From July 2017 to January 2019, 279 female breast cancer patients who underwent 4 cycles of anthracycline treatment in Department of Breast Surgery of the People′s Hospital of Shanxi Medical University were enrolled in the study. The ECG of all patients before treatment showed sinus rhythm and QTc<440 ms. The most common electrocardiographic abnormalities after treatment were the changes of QTc. There were 78 cases with prolonged QTc (≥440 ms, QTc prolongation group) and 201 cases with normal QTc (<440 ms, non-prolongation group). The risk factors of QTc prolongation were analyzed by univariate and multivariate logistic regression. Cardiac toxicity was evaluated according to clinical symptoms and ECG results during treatment.Results:The common ECG abnormalities after treatment were 78 cases of QTc prolongation (28.0%), 22 cases of ST-T changes (7.9%), and 18 cases of sinus bradycardia (6.5%). Univariate analysis showed that there were significant differences in administration of anthracyclines(contained epirubicin in 48 and 73 cases, pirubicin in 10 and 33 cases, doxorubicin in 4 and 12 cases, liposomal doxorubincin in 16 and 83 cases,χ 2=15.54, P<0.01), dexrazoxane use (χ 2=5.43, P=0.02), coronary heart disease (χ 2=4.56, P=0.03), obesity or overweight (χ 2=4.51, P=0.03) between two groups. Multivariate logistic regression analysis showed that the use of different types of anthracyclines ( OR=1.42, 95 %CI: 1.37-1.48, P=0.02) and overweight/obesity ( OR=1.23, 95 %CI: 1.16-1.30, P=0.04) were independent risk facors of QTc prolongation. The liposomal doxorubicin in anthracyclines resulted in a minimum incidence of the QTc prolongation (16.2%, 16/99), while that of epirubicin was up to 39.7% (48/121). Preventive use of dexrazoxane reduced the incidence of the QTc prolongation to 11.4% (4/35). The incidence of the QTc prolongation in breast cancer with coronary heart disease or overweight/obesity was relatively high, which was 4/6 and 34.4%(42/122), respectively. No cardiotoxic symptoms such as chest pain, palpitation and shortness of breath occurred during the treatment, and no fatal arrhythmia such as ventricular tachycardia and ventricular fibrillation was observed in electrocardiogram. Conclusion:Although the incidence of the QTc prolongation in breast cancer patients treated with anthracyclines is high, there is no serious cardiotoxicity such as fatal arrhythmia. Breast cancer patients with coronary heart disease or overweight/obesity are more likely to have the QTc prolongation. Preventive use of dextrazoxan or the selection of liposomal doxorubicin can reduce the incidence of the QTc prolongation.

TORCH, which is considered as a series of pathogens, including the Toxoplasma gondii, Rubella virus, Cytomegalovirus or Herpes simplex virus, often infects the pregnant women to induce the the fetus or newborn infection by transplacental infection or exposure to contaminated genital tract secretions at delivery. Increasing evidence have been confirmed that the infection of TORCH may cause the miscarriage, premature birth, malformed fetus, stillbirth, intrauterine growth retardation, neonatal multiple organ dysfunction and other adverse pregnancy outcomes. For most TORCH-infections cases may lacking the effective treatments during pregnancy, and it is important to achieve the effacing monitoring of TORCH infections before and during pregnancy. The laboratory testing of TORCH has the great significance. However, the consensus opinions still need to improve the the standardization of TORCH testing process and the correct interpretation. Based on the characteristics of the TORCH detection method, this article gives a consensus opinion on the standardized detection and clinical application of TORCH from the laboratory perspective according to the characteristics and types of infection of different pathogens.

Objective: To investigate the content of persistent organic pollutants (POPs) in fish from Dongting Lake. Methods: Ten sample collection points were set in lakeside city Yueyang and Yuanjiang. In July (wet season) and November (dry season) of 2012, 13 common fish species were captured by convenience sampling in Dongting Lake. Two to three fish with similar weight were selected in each season for the same species of fish. After sample preparation and pretreatment, the contents of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), dioxin-like polychlorinated biphenyls (dl-PCBs), indicator polychlorinated biphenyls and polybrominated diphenyls ether (PBDEs) in the samples were determined by high resolution gas chromatographer-high resolution mass spectrometry. Toxicity Equivalents (TEQ) of PCDD/Fs and dl-PCBs were calculated according to the revised toxicity equivalent factor (TEF) of WHO in 2005. The contents of POPs were expressed by median and quavtile. The differences of POPs in fish in different periods were compared by Wilcoxon rank sum test. Results: The content of PCDD/Fs of fish in Dongting Lake in wet season was 12.397 (8.865, 24.964) pg/g, higher than that in the dry season 0.771 (0.490, 1.442) pg/g (P<0.001), and the toxicity equivalent quantity (TEQ) were 0.150 (0.066,0.528) and 0.143 (0.066, 0.235) pg-TEQ/g without statistically significant difference (P>0.05). For the fish in wet and dry season from Dongting Lake,∑dl-PCBs of fish were 66.475 (28.065, 77.794) and 24.205 (18.237, 90.777) pg/g, respectively, and the TEQ were 0.061 (0.046, 0.268) and 0.075 (0.054, 0.182) pg-TEQ/g; ∑ indicative PCBs were 237.764 (153.896, 335.483) and 119.711 (52.171, 408.696) pg/g, respectively; ∑ PBDEs were 106.513 (64.834, 164.860) and 86.837 (61.872, 177.108) pg/g, respectively. The highest content of PCDD/Fs was found in grass carp (198.360 pg/g) in wet season. The higher content of PCBs was found in long-necked fish (2 332.509 pg/g) and PBDEs was found in pelteobagrus fulvidraco (343.857 pg/g), respectively. Conclusion A lower burden was found in fishes from Dongting Lake, and the content of POPs varied in different seasons and fishes.
