A Retrospective Cohort Study on the Comorbidity in 19,264 Chinese Patients of Different Ages with Urticaria.

To examine the prevalence of comorbidities in Chinese urticaria patients and assess medication use patterns across different ages (6-11 years, 12-17 years, above 18 years), a retrospective cohort study was performed in 192,647 urticaria patients within the Health Database. After 1:1 propensity score matching, 166,921 people were divided into the urticaria group and the control group, and the follow-up data were collected within 2 years. During the 12-month and 24-month follow-up period, significant comorbidities identified included allergic rhinitis and asthma, with distinct patterns observed across age groups. Chronic urticaria patients often have complications, such as allergic rhinitis, upper respiratory infection, oropharyngeal infection, and dental caries. The study underscores the need for age-specific treatment strategies in urticaria management.

A method for isolating and culturing ectopic epithelial and stromal cells to study human adenomyosis.

PURPOSE: Although adenomyosis is a common and benign gynecological disease, the specific pathogenesis of this condition is yet to be fully elucidated. It is difficult to culture primary cells of the ectopic endometrial epithelia and stroma from human adenomyosis lesions. Most of the previous of studies on adenomyosis were based on primary eutopic endometrium cells. However, as yet, no efficient protocols have been developed for the isolation, culture or purification of primary ectopic epithelial and stromal cells from human adenomyosis lesions. Therefore, the present study aimed to develop an efficient protocol for the isolation and culture of primary ectopic epithelial and stromal cells from human adenomyosis lesions. METHODS: In the present study, we aimed to obtain ectopic endometrium tissue from human adenomyosis foci and use a simple and operable type I collagenase digestion method for primary culture. Cells were isolated by sterile cell strainer filtration and flow cytometry was performed to identify, purify, and evaluate the viability of isolated ectopic endometrial cells. RESULTS: Using our method, we successfully isolated and cultured highly purified and active ectopic endometrial epithelial and stromal cells from human adenomyosis foci. Ep-CAM was expressed in ectopic epithelial cells of human adenomyosis with a purity of 93.74% and a viability of 80.58%. In addition, CD10 were robustly expressed by ectopic stromal cells in human adenomyosis. Cellular purity and viability were determined to be 96.37 and 93.49%, respectively. CONCLUSION: Our method provides a new experimental model for studying the molecular pathogenesis of human adenomyosis.

GLP1R boosts survival, migration and invasion of endometrial cancer cells and protects against ferroptotic cell death.

BACKGROUND: Despite the strong evidence concerning carcinogenic roles of glucagon-like peptide 1 receptor (GLP1R), the role of this gene in endometrial cancer (EC) remains elusive. This study investigated the properties of GLP1R on EC in vitro. METHODS: The expression of GLP1R in EC was detected by RT-qPCR, immunohistochemistry, and western blotting. Cell viability, cell cycle, apoptosis, migration, invasion and ferroptosis were assessed through CCK-8, flow cytometry, wound healing, transwell, DCFH-DA and western blotting, respectively. RESULTS: We found that GLP1R was up-regulated in EC than normal specimens. It had the highest expression in AN3CA cells. Cell viability, migration and invasion were significantly reduced, while cell cycle arrest and apoptosis were induced following GLP1R knockdown. The malignant biological behaviours of AN3CA cells were investigated when treated with exendin-4 (GLP1R agonist). Moreover, GLP1R lowered intracellular ROS level and expression of SLC7A11, and FTH1, but mitigated GPX4 expression in AN3CA cells. CONCLUSION: In a word, GLP1R was up-regulated in EC and its up-regulation facilitated the proliferative and metastatic potentials, and protected cells from ferroptosis, thereby accelerating EC progression. These data emphasised the potency of GLP1R as a therapeutic agent against EC.

Endometrial cancer (EC) is the second most common form of gynaecologic malignancy, with over 189,000 new cases and about 45,000 deaths worldwide per annum. The effects of glucagon-like peptide 1 receptor (GLP1R) in cancers such as colon and pancreatic cancers have been uncovered. However, whether GLP1R affects EC progression especially ferroptosis process remains elusive. In this study, up-regulation of GLP1R promotes the proliferative and metastatic potentials of EC cells, and protects EC cells from ferroptosis. The opposite results are observed in GLP1R knocking-down. Our study found that GLP1R may exert an oncogene function in EC cells, which can affect proliferative, migrated as well as invasive capacities of EC cells. Moreover, it protected EC cells from ferroptosis. Thus, our results expanded the understanding of the function of GLP1R protein and offered insights into the targeted treatment strategies against EC.

TaBln1, a member of the Blufensin family, negatively regulates wheat resistance to stripe rust by reducing Ca2+ influx.

Blufensin1 (Bln1) has been identified as a susceptibility factor of basal defense mechanisms which is unique to the cereal grain crops barley (Hordeum vulgare), wheat (Triticum aestivum), rice (Oryza sativa), and rye (Secale cereale). However, the molecular mechanisms through which Bln1 regulates the wheat immune response are poorly understood. In this study, we found that TaBln1 was significantly induced by Puccinia striiformis f. sp. tritici (Pst) virulent race CYR31 infection. Knockdown of TaBln1 expression by virus-induced gene silencing reduced Pst growth and development, and enhanced the host defense response. In addition, TaBln1 was found to physically interact with a calmodulin, TaCaM3, on the plasma membrane. Silencing TaCaM3 with virus-induced gene silencing increased fungal infection areas and sporulation and reduced wheat resistance to the Pst avirulent race CYR23 (incompatible interaction) and virulent race CYR31 (compatible interaction). Moreover, we found that the accumulation of TaCaM3 transcripts could be induced by treatment with chitin but not flg22. Silencing TaCaM3 decreased the calcium (Ca2+) influx induced by chitin, but silencing TaBln1 increased the Ca2+ influx in vivo using a noninvasive micro-test technique. Taken together, we identified the wheat susceptibility factor TaBln1, which interacts with TaCaM3 to impair Ca2+ influx and inhibit plant defenses.

Clinical efficacy and safety of trimonthly administration of goserelin acetate 10.8 mg in premenopausal Chinese females with symptomatic adenomyosis: a prospective cohort study.

OBJECTIVE: This prospective cohort study aimed to compare the clinical efficacy and safety of goserelin 10.8 mg administered trimonthly with goserelin 3.6 mg administered monthly in premenopausal females with symptomatic adenomyosis. METHODS: We recruited 139 premenopausal females with adenomyosis who complained of dysmenorrhea and/or menorrhagia. The first group (n = 70) received a single subcutaneous injection of goserelin 10.8 mg, and the second group (n = 69) received monthly subcutaneous goserelin 3.6 mg administered for 3 months. Follow-up was performed at the outpatient department after 12 weeks. RESULTS: Ultimately, 130 patients completed the study, including 68 and 62 patients in the goserelin 10.8 mg (n = 70) and 3.6 mg (n = 69) groups, respectively. We observed a significant decrease in the dysmenorrhea (NRS) score, uterine volume, and cancer antigen 125 (CA125) levels, and a significant increase in hemoglobin (HGB) levels in both treatment groups. There was no significant difference between the two groups. The sum of the adverse event scores was slightly higher in the goserelin 3.6 mg than in the 10.8 mg group. CONCLUSIONS: The clinical efficacy of trimonthly administration of goserelin 10.8 mg was equivalent to monthly 3.6 mg dosing and was non-inferior regarding safety and tolerability. Hence, it can be a more cost-effective and convenient alternative treatment option in premenopausal females with symptomatic adenomyosis. TRIAL REGISTRATION: ChiCTR2200059548.

A Chiral Metal-Organic Framework Prepared on Large-Scale for Sensitive and Enantioselective Fluorescence Recognition.

MOF-based luminescent sensors have garnered considerable attention due to their potential in recognition and discrimination with high sensitivity, selectivity, and fast response in the last decades. Herein, this work describes the bulk preparation of a novel luminescent homochiral MOF, namely, [Cd(s-L)](NO3)2 (MOF-1), from an enantiopure pyridyl-functionalized ligand with rigid binaphthol skeleton under mild synthetic condition. Except for the features of porosity and crystallinity, the MOF-1 has also been characterized with water-stability, luminescence, and homochirality. Most important, the MOF-1 exhibits highly sensitive molecular recognition toward the4-nitrobenzoic acid (NBC) and moderate enantioselective detection of proline, arginine, and 1-phenylethanol.

Survival prediction optimization of acute myeloid leukaemia based on T-cell function-related genes and plasma proteins.

Interactions between acute myeloid leukaemia (AML) cells and immune cells are postulated to corelate with outcomes of AML patients. However, data on T-cell function-related signature are not included in current AML survival prognosis models. We examined data of RNA matrices from 1611 persons with AML extracted from public databases arrayed in a training and three validation cohorts. We developed an eight-gene T-cell function-related signature using the random survival forest variable hunting algorithm. Accuracy of gene identification was tested in a real-world cohort by quantifying cognate plasma protein concentrations. The model had robust prognostic accuracy in the training and validation cohorts with five-year areas under receiver-operator characteristic curve (AUROC) of 0.67-0.76. The signature was divided into high- and low-risk scores using an optimum cut-off value. Five-year survival in the high-risk groups was 6%-23% compared with 42%-58% in the low-risk groups in all the cohorts (all p values <0.001). In multivariable analyses, a high-risk score independently predicted briefer survival with hazard ratios of death in the range 1.28-2.59. Gene set enrichment analyses indicated significant enrichment for genes involved in immune suppression pathways in the high-risk groups. Accuracy of the gene signature was validated in a real-world cohort with 88 pretherapy plasma samples. In scRNA-seq analyses most genes in the signature were transcribed in leukaemia cells. Combining the gene expression signature with the 2017 European LeukemiaNet classification significantly increased survival prediction accuracy with a five-year AUROC of 0.82 compared with 0.76 (p < 0.001). Our T-cell function-related risk score complements current AML prognosis models.

GnRH receptor mediates lipid storage in female adipocytes via AMPK pathway.

Objective: Due to high levels of serum gonadotropin-releasing hormone (GnRH), perimenopausal or menopausal women, girls with central precocious puberty, women of polycystic ovary syndrome, and females receiving long-term GnRH agonist (GnRHa) treatment are at substantially higher risk of developing obesity. However, it remains poorly understood how GnRH affects body weight. Here, we explored whether the gonadotropin-releasing hormone receptor (GnRHR) was expressed in adipocytes and how GnRHR mediated lipid accumulation and the development of obesity. Methods: The samples were from 18 patients with benign tumors operated between 01/2018 and 06/2018 at the Women's Hospital School of Medicine Zhejiang University. Immunofluorescence, Western Blotting, and RT-PCR were used to detect whether the GnRH receptor was expressed in the specimens and human preadipocytes-subcutaneous (HPA-s). The GnRH receptor agonist diphereline with different concentrations was used to stimulate the HPA-s cells for 24, 48, and CCK-8 was used to detect cell proliferation. Oil red-O staining was used to detect lipid droplets in mature adipocytes. The phosphorylation of AMPK-Ser485/Thr172 was detected by Western Blotting. Results: GnRH receptor was expressed in all 18 human subcutaneous adipose tissue specimens. Cultured HPA-s expressed the GnRH receptor, and the expression increased during the process of cell maturation. The GnRH receptor agonist diphereline can stimulate the proliferation of HPA-s cells, which can advance the earliest occurrence of lipid droplets in HPA-s cells and the occurrence of lipid droplets in 50% cells by 1-2 days. Diphereline can stimulate the increase in the number of lipid droplets in mature adipocytes. The phosphorylation level of AMPK-Ser485/Thr172 in mature adipocytes was decreased by diphereline. Conclusion: The GnRH receptor was expressed in adipocytes. As adipocytes mature, GnRH receptor expression gradually increased. GnRHa stimulates the proliferation of HPA-s, promotes adipocyte maturation, increases the formation of lipid droplets in mature adipocytes, and inhibits the activation of the AMPK pathway in adipocytes. Our findings may elucidate the mechanism of obesity in these female populations and provide some evidence on how GnRH contributes to obesity. Additionally, these results provide theoretical support for further research on the mechanisms of obesity, thus enhancing our understanding of the functional diversity of GnRH and establishing a new theoretical basis for the impact of GnRH on metabolism.

Recepteur d'origine nantais contributes to the development of endometriosis via promoting epithelial-mesenchymal transition of a endometrial epithelial cells.

Endometriosis is a benign, chronic inflammatory disease that commonly occurs in reproductive-aged women. Epithelial-mesenchymal transition (EMT) of endometrial epithelial cells plays an important role in the development of endometriosis. Recepteur d'origine nantais (RON), a receptor tyrosine kinase, has been reported to promote EMT and progression in tumours. However, whether and how RON mediates the EMT and endometriosis development is not known. Here, we found that RON activation could improve the migratory and invasive capabilities, change cellular morphologies, and decrease expression of E-cadherin and increase expression of N-cadherin in endometrial epithelial cells. Inhibition or knockdown of RON expression suppressed the migration and invasion of endometrial epithelial cells. Our studies also indicated that RON played its part in endometrial epithelial cells through protein kinase B (Akt) and mitogen-activated protein kinase (MAPK) pathways. Treatment with a RON inhibitor could decrease the number of ectopic lesions in a mouse model of endometriosis and mediate expression of EMT markers in endometriotic lesions. These data suggest that RON contributed to endometriosis development by promoting EMT of endometrial epithelial cells. Therefore, RON may be a new therapeutic target for endometriosis.

OMIP 071: A 31-Parameter Flow Cytometry Panel for In-Depth Immunophenotyping of Human T-Cell Subsets Using Surface Markers.

Dissecting the functional diversity of T cells is critical in elucidating mechanisms and in developing therapies for various diseases. Here, we designed a 31-parameter (29-color) panel to enable the characterization of T-cell subsets and immunophenotyping of the human peripheral blood and lymph nodes using cell surface staining. In addition to adaptive T-cell markers, TCR Vα24-Jα18, TCR γδ, TCR Vɑ7.2, and CD161 were included to identify iNKT, γδ T, and MAIT cells, respectively, which are innate-like T cells. C-X-C chemokine receptors (CXCR3, CXCR4, CXCR5, CXCR6) and C-C motif chemokine receptors (CCR4, CCR6, CCR7) were included to enable the identification of Th cell subsets (Th1, Th2, Th17), Tfh cell subsets (Tfh1, Tfh2, Tfh17), and Th cells with specific homing capacities. Furthermore, in this panel, we also used markers for assessing cell differentiation (CD45RO, CD7), activation (CD57, CD95, HLA-DR) and the expression of some cosignaling molecules (PD-1, NKG2D, CD28). Particularly, CD69 and CD103 were included for the further analysis of tissue resident memory T (Trm) cells. This panel would enable the in-depth immunophenotyping of human T-cell subsets, and may be applied in the monitoring, prognosis, and mechanistic studies of various immune-related diseases.

Efficacy of Single Level Versus Double Levels Surgery of Percutaneous Disc Nucleoplasty (PDN) Approach in Treating Lumbar Disc Herniation.

BACKGROUND Although percutaneous disc nucleoplasty (PDN) has been widely applied in treating lumbar disc herniation (LDH) in recent years, the efficacy of surgical levels for PDN on LDH has been reported in limited studies. This study aimed to explore and compare the efficacy of surgical levels (single level vs double level) of PDN in treating LDH. MATERIAL AND METHODS All patients diagnosed with LDH from January 2012 to December 2014 in our hospital who underwent PDN were included in this study. Patients were divided into a single-level group and double-level group based on the number of discs/surgical treatment levels. The improvement of visual analog scale (VAS) score, patient satisfaction, and reoperation occurrence were compared between the 2 groups. RESULTS Of 105 total patients, 75 patients were treated with single-level treatment and 30 patients with double-level treatment. VAS for leg pain and patient satisfaction scores in the double-level group were worse than those in the single-level group at 6 months after surgery (P<0.05). Among all 105 patients, the incidence of reoperation was 11.4%. Also, there was a marked difference in reoperation occurrence at 6 months after surgery between the single-level (6.7%) and double-level (23.3%) groups; however, the difference was not statistically significant (P=0.05). CONCLUSIONS PDN is a safe and minimal-invasive approach, which could effectively treat LDH. The number of surgical levels might be an important factor influencing the efficacy of PND. Caution should be exercised to strictly follow the clinical indications for nucleoplasty.

A new trick for an old dog: The application of mifepristone in the treatment of adenomyosis.

Adenomyosis is also called internal endometriosis and affects about 20% of reproductive-aged women. It seriously reduces life quality of patients because current drug therapies face with numerous challenges. Long-term clinical application of mifepristone exhibits wonderful therapeutic effects with mild side-effects in many disorders since 1982. Since adenomyosis is a refractory disease, we investigate whether mifepristone can be applied in the treatment of adenomyosis. In this study, we investigated the direct effects of mifepristone on human primary eutopic endometrial epithelial cells and stromal cells in adenomyosis. We found that mifepristone causes cell cycle arrest through inhibiting CDK1 and CDK2 expressions and induces cell apoptosis via the mitochondria-dependent signalling pathway in endometrial epithelial cells and stromal cells of adenomyosis. Furthermore, mifepristone inhibits the migration of endometrial epithelial cells and stromal cells through decreasing CXCR4 expression and restricts the invasion of endometrial epithelial cells via suppression of epithelial-mesenchymal transition in adenomyosis. We also found that mifepristone treatment decreases the uterine volume, CA125 concentration and increases the haemoglobin concentration in serum for adenomyosis patients. Therefore, we demonstrate that mifepristone could serve as a novel therapeutic drug in the treatment of adenomyosis, and therefore, the old dog can do a new trick.

Activation of ATF3/AP-1 signaling pathway is required for P2X3-induced endometriosis pain.

STUDY QUESTION: Does P2X ligand-gated ion channel 3 (P2X3) play a role in endometriosis pain? SUMMARY ANSWER: Upregulation of P2X3 in dorsal root ganglia (DRG) tissues via the activating transcription factor 3 (ATF3)/activator protein (AP)-1 pathway contributed to endometriosis-associated hyperalgesia, which could be attenuated by the chitosan oligosaccharide stearic acid (CSOSA)/liposomes (LPs)/SP600125 delivery system. WHAT IS KNOWN ALREADY: Infiltrating nerve fibers and elevated nociceptors in endometriotic lesions are associated with endometriosis pain. P2X3 has been demonstrated to play an important role in neuropathic pain. STUDY DESIGN, SIZE, DURATION: A rat model of endometriosis was used to investigate the signaling pathways involved in P2X3-induced pain. PARTICIPANTS/MATERIALS, SETTING, METHODS: Degrees of hyperalgesia, endogenous adenosine 5'-triphosphate (ATP) contents and P2X3 expression levels in endometriotic lesions and DRG tissues were detected in a rat model of endometriosis. The expression levels of ATF3 and P2X3 were measured using qRT-PCR, western blot analysis and immunofluorescence analysis after adenosine 5'-diphosphate (ADP) exposure in DRG cells. Plasmids encoding ATF3 and its siRNA were used to investigate the role of ATF3 on ADP-induced P2X3 upregulation. The activity of ATF binding to the P2X3 promoter was evaluated by using chromatin immunoprecipitation (CHIP) and luciferase assays. SP600125, an inhibitor of c-JUN N-terminal kinase, was wrapped in CSOSA/LPs delivery system and its inhibitory effects on ADP-induced upregulation of P2X3 in DRG cells and endometriosis-induced hyperalgesia in rats were tested. MAIN RESULTS AND THE ROLE OF CHANCE: The concentrations of endogenous ATP and expression levels of P2X3 were significantly increased in both endometriotic lesions and DRG tissues in endometriosis rat models and were found to be positively correlated with the severity of hyperalgesia. In DRG cells, P2X3 expression levels were elevated by ADP stimulation, but dramatically inhibited by blocking ATF3 with its siRNA and SP600125. CHIP and luciferase assay showed that ADP increased the binding of ATF3 to the P2X3 promoter, resulting in an increase in P2X3 expression levels. In the CSOSA/LPs/SP600125 delivery system, the drug could be effectively concentrated in endometriotic lesions, and it could alleviate endometriosis-induced hyperalgesia, reduce the size of endometriotic lesions and attenuate upregulated P2X3 expression levels in endometriosis rat models. LARGE SCALE DATA: N/A. LIMITATIONS, REASONS FOR CAUTION: Changes in the sensitivity and function of P2X3 caused by endometriosis need to be further investigated. WIDER IMPLICATIONS OF THE FINDINGS: This study indicates that ATP and the P2X3 receptor are involved in endometriosis pain, thus providing a novel therapeutic approach for the treatment of endometriosis pain by targeting the P2X3 receptor. STUDY FUNDING/COMPETING INTEREST(S): This work was funded by National Key R&D Program of China (Grant No. 2017YFC1001202) and National Natural Science Foundation of China (Grant Nos. 81974225, 81671429 and 81471433). There are no competing interests.

The new application of mifepristone in the relief of adenomyosis-caused dysmenorrhea.

Background: Adenomyosis is a quite common gynecological disorder and above 30% of patients have typical secondary and progressive dysmenorrhea. Current treatments still have many disadvantages and thereby the novel treatment aiming to relieve dysmenorrhea still needs to be further investigated. Mifepristone is a wonderful drug because it is effective, safe and cheap in many diseases including adenomyosis. In this study, we aim to investigate if mifepristone could be used in the treatment of adenomyosis-associated dysmenorrhea. Methods: Human primary endometrial epithelial and stromal cells from adenomyosis patients were isolated and treated with mifepristone. RNA-sequencing was then performed to detect the gene changes of pain-related inflammatory mediators. Meanwhile, the effect of mifepristone on the infiltration and degranulation of mast cells were investigated in adenomyosis lesions. Additionally, the role of mifepristone on the density of nerve fibers was also studied in the ectopic endometrium. At last, to evaluate the therapeutic efficacy of mifepristone on dysmenorrhea of adenomyosis, twenty participants were included and the visual analog scale (VAS) score was assessed and compared before and after treatment with mifepristone. Results: We demonstrated that mifepristone reduced the secretion of IL-6 and TNF-α from endometrial epithelial and stromal cells, restricted the infiltration and degranulation of mast cells in eutopic and ectopic endometrium and decreased the density of nerve fibers by inhibiting the migration capacity of nerve cells in adenomyosis. Meanwhile, we found that mifepristone could significantly relieve dysmenorrhea of adenomyosis. Conclusion: The findings demonstrated that mifepristone could be applied in the treatment of dysmenorrhea for the adenomyosis patients.

Normal increases in insulin-stimulated glucose uptake after ex vivo contraction in neuronal nitric oxide synthase mu (nNOSµ) knockout mice.

Nitric oxide (NO) is involved in skeletal muscle glucose uptake during exercise and also in the increase in insulin sensitivity after exercise. Given that neuronal nitric oxide synthase (NOS) isoform mu (nNOSµ) is a major isoform of NOS in skeletal muscle, we examined if the increase in skeletal muscle insulin-stimulated glucose uptake 3.5 h following ex vivo contraction of extensor digitorum longus (EDL) is reduced in muscles from nNOSµ+/- and nNOSµ-/- mice compared with nNOSµ+/+ mice. 3.5 h post-contraction/basal, muscles were exposed to saline or insulin (120µU/ml) with or without the presence of the NOS inhibitor NG-monomethyl-L-arginine (L-NMMA) during the last 30 min and glucose uptake was determined by radioactive tracers. Skeletal muscle insulin-stimulated glucose uptake from nNOSµ+/+, nNOSµ+/-, and nNOSµ-/- mice increased approximately twofold 3.5 h following ex vivo contraction when compared to rest. L-NMMA significantly attenuated this increase in muscle insulin-stimulated glucose uptake by around 50%, irrespective of genotype. Low levels of NOS activity were detected in muscles from nNOSµ-/- mice. In conclusion, NO mediates increases in mouse skeletal muscle insulin response following ex vivo contraction independently of nNOSµ.

Is there a correlation between inflammatory markers and coagulation parameters in women with advanced ovarian endometriosis?

BACKGROUND: Endometriosis is defined as a chronic inflammatory disease. Recent studies have shown that increased coagulation parameters including fibrinogen and platelets are associated with endometriosis. The objective of this study was to determine the levels of inflammatory markers and coagulation parameters and their correlations in women with endometriomas compared to those with benign ovarian cysts or normal pelvic anatomy. METHODS: Between June 2015 and June 2017, a total of 548 women who underwent laparoscopic/laparotomic surgery for ovarian endometriomas (OMA group, n = 226), non-endometriosis benign ovarian cysts (Cyst group, n = 210) and tubal reanastomosis (Control group, n = 112) were recruited in this study. Inflammatory markers including c-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and coagulation parameters including platelet count, thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time, and plasma fibrinogen as well as CA-125 were determined. RESULTS: Compared with Cyst group and Control group, TT and PT in OMA group were significantly shorter and plasma fibrinogen levels were significantly higher (P < 0.05). Moreover, the levels of plasma fibrinogen were positively correlated with CRP, NLR and PLR (P < 0.05). In addition, the confidence intervals for the area under the curve (AUC) for CA-125 × fibrinogen were significantly higher than those for CA-125 (0.904-0.952 vs. 0.899-0.949) in the diagnosis of endometrioma. CONCLUSIONS: These results indicate that women with endometriomas demonstrate a hypercoagulable status due to the inflammatory nature of endometriosis. The combined determination for CA-125 and fibrinogen demonstrate a higher area under the curve than the single detection of CA-125 in those with endometriomas compared to these with benign ovarian cysts. TRIAL REGISTRATION: This study was approved by the Human Ethics Committee of the Women's Hospital, School of Medicine, Zhejiang University (No.20170174) and all women provided written informed consent.

Hippocampal neuron loss and astrogliosis in medial temporal lobe epileptic patients with mental disorders.

Hippocampal neuron loss and reactive astrogliosis are pathological features of medial temporal lobe epilepsy. Here, the expression of hippocampal astrogliosis-associated genes are studied in subjects with medial temporal lobe epilepsy and mental disorders (such as depression, anxiety and psychiatric comorbidities). The relationship between functional changes in hippocampus astrocytes and concurrent mental disorders are discussed. Nissl staining identified medial temporal lobe epilepsy-induced neuronal loss in the CA1 region of hippocampus. Quantitative real-time polymerase chain reaction and immunofluorescence technology were used to detect hippocampus glial fibrillary acidic protein, metallothionein, and aquaporin-4. The hippocampus area of subjects with medial temporal lobe epilepsy (with or without mental disorders) were smaller than the control group. Hippocampal neuronal loss and astrogliosis were more obvious in groups of medial temporal lobe epileptic patients with mental disorders. Relative protein levels of glial fibrillary acidic protein, metallothionein-I/II, and aquaporin-4 were significantly higher in subjects with medial temporal lobe epilepsy than seen in controls. Medial temporal lobe epileptic patients with mental disorder or depression had elevated metallothionein-I/II protein level when compared to controls and medial temporal lobe epileptic patients without mental disorder. Protein levels of glial fibrillary acidic protein and aquaporin-4 in medial temporal lobe epileptic patients with mental disorders were significantly lower than that in medial temporal lobe epileptic patients with no mental disorder. It is concluded that functional changes in hippocampus astrocytes are associated with mental disorders in medial temporal lobe epileptic patients and the astrogliosis-related genes of glial fibrillary acidic protein, metallothionein-I/II and aquaporin-4, are involved in this process.

Clinical Research on Prevention and Treatment of Respiratory Tract Complications With Acupoint Application After Operation Under General Anesthesia.

There are various respiratory tract complications in patients undergoing general anesthesia, with postoperative sore throat (POST) being the most commonly seen. Although measures have been taken to prevent and treat POST in clinical practice, the control of POST is still not satisfactory. In this study, 880 ASA patients with grade I to II general anesthesia were randomly assigned into control group and experimental group. After patients entered into the operating room, the plasters were applied to the designated points (Tianzhu, Lianquan, Dazhui, etc), and the clinical efficacy of acupoint application in prevention and treatment of respiratory tract complications after general anesthesia was observed. The results showed that patients starting using acupoint application before operation could significantly reduce the incidence of postoperative respiratory tract complications, and the effects lasted for up to 24 hours. In this study, acupoint application was used, providing a simple, safe, efficient, and durable approach to prevent and treat respiratory tract complications after operation under general anesthesia.

[Stratified treatment and management of adenomyosis].

In recent years, surgical and non-surgical excision and drug therapy have replaced hysterectomy as the main therapeutic modalities for adenomyosis. It is suggested that the precise clinical diagnosis should be based on the reconstruction of digitized three-dimensional model with original image data of adenomyosis. Patients' age and clinical manifestations should also be considered, and the patients should be stratified according to reproductive requirements, so as to determine the best treatment. In view of the infiltration and diffuse growth of adenomyosis lesions in the myometrium of the uterus, it is suggested that long-term drug management should be adopted after surgical or non-surgical lesion resection.Gonadotropin releasing hormone agonists, levonorgestrel-releasing intrauterine system, dienogest and short-acting oral contraceptives should be recommended to consolidate the curative effect in order to delay the progress of the disease and prevent recurrence.

[Progress on medical treatment in the management of adenomyosis].

Drug therapy plays an important role in alleviating the symptoms related to adenomyosis, improving the curative effect of surgery, delaying the progress of disease and promoting assisted reproduction. Non-steroidal anti-inflammatory drugs (NSAIDs) are the first choice to control pain associated with adenomyosis, and are the only choice for patients with recent fertility requirements; steroid hormones, gonadotropin releasing hormone agonists and mifepristone can effectively relieve pain and control uterine bleeding, among which oral contraceptives, levonorgestrel-releasing intranterine system (Mirena) and dienogest are more effective and commonly used in clinic. Drug selection should be based on patient's age, symptoms, uterine size, fertility requirements and economical conditions. At present, there is no specific drug for adenomyosis, and symptoms are easy to recur after drug withdrawal, so the long-term drug use needs further study.
