Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Objective : To pathological changes and inducible nitric oxide synthase(iNOS), phosphorylated insulin receptor substrate 1 serine 307(p-IRS1ser 307), phosphorylated protein kinase B serine 473(p-AKTser 473), glycogen synthase kinase-3β(GSK-3β), and gluconeogenic synthase(GS) proteins were observed in the liver of rats under the condition of chronic intermittent hypoxia-replicated oxygen in control. And to explore the role of iNOS/IRS1/AKT/GSK-3β signaling pathway in chronic intermittent hypoxia-induced insulin resistance. Methods : Forty SD rats were randomly divided into a control group(NC group) and an experimental group(CIH group), with 20 rats in each group. The NC group was placed in a normoxic environment for 12 weeks, while the CIH group was first subjected to intermittent hypoxia for 8 weeks, and then resumed normoxic rearing until the 12th week. Fasting blood glucose(FBG) and fasting insulin(FINS) were measured at baseline, week 8 and week 12, and liver tissues were taken for pathology and measurement of iNOS, p-IRS1ser 307, p-AKTser 473, GSK3β and GS levels, to compare the differences between groups. Results: t baseline, there was no significant difference in liver pathology between the two groups, and the observed indexes were not statistically significant(P>0.05); at 8 weeks, compared with the NC group, liver pathology in the CIH group showed significant disorganization of hepatic blood sinusoids and hepatocyte cords, obvious hepatocyte edema, smaller nuclei, increased lymphocyte infiltration, and a small number of fat vacuoles, significantly higher levels of FBG, FINS, insulin resistance index(HOMA-IR), iNOS mRNA, p-IRS1ser 307 protein, GSK-3β protein levels, and decreased p-AKTser 473 protein and GS protein levels, all of which were statistically significant(allP<0.05). IRS1ser 307 protein, GSK-3β protein levels were increased, p-AKTser 473 protein and GS protein levels were decreased, and the differences were statistically significant(allP<0.05); at 12 weeks, no lymphocyte infiltration was seen in the CIH group compared with that of the NC group and fat vacuoles significantly increased, and there was no improvement in the other pathological damage that had already occurred, and the levels of p-AKTser 473 protein significantly increased. AKTser 473 protein level significantly increased, p-IRS1ser 307 protein and GS protein levels were significantly reduced, all of which were statistically significant(allP<0.05), and the rest of the observational indexes were not statistically significant. Pearson′s correlation analysis showed that HOMA-IR of CIH group was significantly positively correlated with the levels of iNOS mRNA, p-IRS1ser 307 protein, and GSK-3β protein at 8 weeks(r=0.874, 0.817,0.872;allP<0.05), and significantly negatively correlated with the levels of p-AKTser 473 protein and GS protein(r=-0.886,-0.879;allP<0.05). Conclusion Chronic intermittent hypoxia can lead to hepatic pathological damage that cannot be reversed even by reoxygenation interventions and may mediate the development of insulin resistance by upregulating the IRS1/AKT/GSK-3β signaling pathway through the upregulation of iNOS mRNA expression.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

With the development of cancer treatment,patient survival rates have substantially improved.But cancer therapies may come along with potential cardiotoxic effects resulting in cardiovascular disease with increased morbidity and mortality.Ultimately,patients may survive their malignancy but die as a result of cancer treatment.It is crucial that being able to identify cardiovascular damage early and develop strategies that may ameliorate the damage secondary.Cardiovascular magnetic resonance imaging can provide a"one-stop"assessment of cardiac architecture,cardiac function,myocardial tissue characteristics,and cardiac macrovascular hemodynamics,and it is useful in assessing cardiovascular injury,particularly early injury.The objective of this review is to review the application and progress of various cardiovascular magnetic resonance imaging methods in the evaluation of cancer treatment-related cardiovascular disease.

Objective:To study the factors influencing survival after radical resection in patients with intrahepatic cholangiocarcinoma (ICC), and to construct a nomogram on survival prediction.Methods:The clinical data of 139 patients with ICC who underwent radical resection at the People's Hospital of Zhengzhou University from June 2018 to December 2021 were retrospectively analyzed. There are 69 males and 70 females, aged (59.5±10.2) years old. These patients were divided into two groups based on a 3: 1 ratio by using the random number method: the test group ( n=104) and the validation group ( n=35). Data from the test group was used to construct a nomagram and data from the validation group was used to validate the predictive power of the nomagram. Univariate and multivariate Cox regression analyses were used to analyse factors influencing survival on the test group patients and to construct a nomogram. The predictive accuracy of the nomogram was determined by receiver operating characteristic (ROC) curves, concordance index (C-index) and calibration curves. Results:The results of the multivariate regression analysis showed that a combined hemoglobin, albumin, lymphocyte and platelet immunoinflammation (HALP) score <37.1 ( HR=1.784, 95% CI: 1.047-3.040), CA19-9 > 35U/ml ( HR=2.352, 95% CI: 1.139-4.857), poorly differentiated tumor ( HR=2.475, 95% CI: 1.237-4.953) and vascular invasion ( HR=1.897, 95% CI: 1.110-3.244) were independent risk factors that affected prognosis of patients with ICC after radical resection (all P<0.05). The AUCs of the nomogram in the test group in predicting the overall survival at 1, 2 and 3 years of patients with ICC after radical resection were 0.808, 0.853 and 0.859, respectively. There was good consistency between the prediction of the nomogram and actual observation. The predicted C-index of the total survival period of the test group was 0.765 (95% CI: 0.704-0.826), and the C-index of the validation group was 0.759 (95% CI: 0.673-0.845). Conclusion:A HALP score <37.1, CA19-9>35 U/ml, poorly differentiated tumour and vascular invasion were independent risk factors for prognosis of ICC patients after radical resection. The nomogram was established based on the above factors and showed good performance in predicting overall survival after radical resection in patients with ICC.

Objective:To construct a nomogram prediction model for survival after radical surgical resection of intrahepatic cholangiocarcinoma (ICC) based on the albumin-bilirubin index (ALBI), and to evaluate its predictive efficacy.Methods:From January 2016 to January 2020, 170 patients with ICC who underwent radical surgical resection at the People's Hospital of Zhengzhou University were retrospectively analyzed. There were 90 males and 80 females, aged (58.5±10.6) years old. Based on a ratio of 7∶3 by the random number table, the patients were divided into the training set ( n=117) and the internal validation set ( n=53). The training set was used for nomogram model construction, and the validation set was used for model validation and evaluation. Follow up was conducted through outpatient reexamination and telephone contact. The Kaplan-Meier method was used for survival analysis, and a nomogram was drawn based on variables with a P<0.05 in multivariate Cox regression analysis. The predictive strength of the predictive model was evaluated by analyzing the consistency index (C-index), calibration curve, and clinical decision curve of the training and validation sets. Results:Multivariate Cox regression analysis showed that carbohydrate antigen 19-9 (CA19-9) ≥37 U/ml ( HR=1.99, 95% CI: 1.10-3.60, P=0.024), ALBI≥-2.80 ( HR=2.43, 95% CI: 1.40-4.22, P=0.002), vascular tumor thrombus ( HR=2.34, 95% CI: 1.40-3.92, P=0.001), and the 8th edition AJCC N1 staging ( HR=2.18, 95% CI: 1.21-3.95, P=0.010) were independent risk factors affecting postoperative survival of ICC patients after curative resection. The predictive model constructed based on the above variables was then evaluated, and the C-index of the model was 0.76. Calibration curve showed the predicted survival curve of ICC patients at 3 years after surgery based on the model was well-fitted to the 45° diagonal line which represented actual survival. Clinical decision curve analysis showed that the model had a significant positive net benefit in both the training and validation sets. Conclusion:The nomograph model for survival rate after radical resection of ICC was constructed based on four variables: ALBI, CA19-9, vascular tumor thrombus, and AJCC N staging (8th edition) in this study. This model provided a reference for more accurate prognosis evaluation and treatment selection plan for ICC patients.

Objective:To evaluate the efficacy and safety of a novel domestic pulmonary thromoboectomy system Tendvia TM in the treatment for high-risk patients complicated with acute pulmonary embolization (APE). Methods:The study was designed as a prospective single-center clinical trial. Twenty-four high-risk patients with APE were recruited and underwent percutaneous mechanical thromoectomy (PMT) with the Tendvia TM pulmonary thromoboectomy system. The primary efficacy endpoint was the reduction of RV/LV ratio at the post-operative 48 h. The secondary efficacy endpoints included technical success rate, mean pulmonary arterial pressure (mPAP), arterial PaO 2 and the instant post-operative thrombus clearance rate. The evaluation of the safety included the intraoperative complications and related complications during the follow-up period associated with the PMT operation and the major adverse event (MAE) rate within the post-operative 48 h. The pre-and post-operative data were compared with paired sample t-test or Wilcoxon rank sum test to evaluate the efficacy and safety of Tendvia TM pulmonary thromoboectomy system. Results:The technical success rate of PMT with Tendvia TM pulmonary thromoboectomy system was 100% (24/24). The 48 h pre-operative RV/LV ratio was 1.19±0.25 and the post-operative RV/LV ratio was 0.82±0.16. The mean RV/LV ratio of the patients was decreased by 0.37±0.25 at post-operative 48 h with significant statistical difference ( t=7.03, P<0.001). The 48 h pre-operative mPAP was (31.09±6.09) mmHg and the post-operative mPAP was (25.91±4.36) mmHg. The mPAP of the patients was reduced by 5.18 mmHg at post-operative 48 h with significant statistical difference ( t=6.73, P<0.001). The pre-operative PaO 2 was (74.66±11.28) mmHg and the post-operative PaO 2 was (88.01±10.57) mmHg. The pressure of oxygen in artery was increased by 13.36 mmHg. The differences were statistically significant( t=-4.08, P<0.001). The rate of thrombus removal was 68.17%±22.66%. 87.5% (21 cases) of patients achieved a thrombus removal greater than grade Ⅱ. One patient underwent catheter directed thrombolysis (CDT) after PMT based on the evaluation of operator. The patient′s thrombus removal achieved grade Ⅲ after 48 h and the CDT was ceased. Hemoptysis occurred intra-operatively in one case underwent PMT and the symptom of the patient was alleviated with conservative medication. The MAE incidence within the post-operative 48 h was 4.17% (1/24). No device-related mortality or all-cause mortality occurred in the trial. Conclusions:The Tendvia TM pulmonary thromoboectomy system is a safe and effective device to remove the pulmonary arterial thrombus for the treatment of patients with APE. The Tendvia TM pulmonary thromoboectomy system can be a new choice in the treatment for the patients with APE.

ObjectiveTo explore the effect of Baitouweng Tang （BTWT） on the apoptosis of human colorectal cancer HCT116 cells and decipher the underlying mechanism based on the Hedgehog （Hh） signaling pathway. MethodHCT116 cells were treated with BTWT （25， 50， 100， 200， 500， 750， and 1 000 mg·L^-1） for 24 h， and then the cell proliferation was detected by methyl thiazolyl tetrazolium （MTT） colorimetry. Five groups were designed for the treatment of HCT116 cells， including a blank control group， BTWT groups （125， 250， and 500 mg·L^-1）， and a positive control （5-fluorouracil， 5-FU， 40 mmol·L^-1） group. The cell morphology was observed under an inverted microscope. The migration of the cells was detected by scratch test， and the apoptosis by Hoechest 33324/propidium iodide （PI） staining and flow cytometry. Western blot was employed to determine the protein levels of sonic hedgehog （SHh）， GLI family zinc finger protein 1 （Gli1）， smoothened （Smo）， suppressor of fused （SuFu）， cellular-myelocytomatosis viral oncogene （c-Myc）， and the apoptosis-related proteins B-cell lymphoma-2 （Bcl-2） and Bcl-2-associated X protein （Bax）. The quantitative real-time reverse transcription PCR （Real-time PCR） was employed to determine the mRNA levels of Bax， Bcl-2， SHh， Gli1， Smo， SuFu， and c-Myc. ResultCompared with the blank control group， BTWT changed the cell morphology （making the cell become round with dense nucleus）， inhibited the proliferation of HCT116 cells in a dose-dependent manner， decreased the ability of migration （P<0.05， P<0.01）， and increased apoptotic cells. Compared with the blank control group， BTWT （500 mg·L^-1） treatment for 24 h up-regulated the protein and mRNA levels of Bax （P<0.05， P<0.01） and down-regulated the protein and mRNA levels of Bcl-2 in HCT116 cells （P<0.05， P<0.01）. Moreover， the treatment down-regulated the mRNA and protein levels of SHh， Gli1， Smo， and c-Myc （P<0.05， P<0.01） and up-regulated the mRNA and protein levels of SuFu （P<0.05， P<0.01）. ConclusionBTWT inhibited the proliferation and migration and induced the apoptosis of colorectal cancer HCT116 cells by down-regulating the Hh signaling pathway.

【Objective】 To investigate the establishment of multi-center haemovigilance (HV) and the monitoring of adverse reactions to blood donation (ARBD), in order to provide basis for the management of blood donors. 【Methods】 The operation of HV was investigated by questionnaire. The total number of blood donations (including plateletpheresis) and ARBD cases occurred in each blood center from 2014 to 2018 were analyzed. 【Results】 Among the 24 blood centers in this survey, only nine got HV operated. The incidence of ARBD of 19 blood centers that fulfilled the questionnaire was in the range of (0.003~1.151) %. The change trend of number and incidence of ARBD cases were indeterminate. 【Conclusion】 Most blood centers did not got HV established. The incidence of ARBD varied greatly and was indeterminate. The application of HV should be further improved to strengthen ARBD management.

Obesity is increasingly prevalent globally, searching for therapeutic agents acting on adipose tissue is of great importance. Equisetin (EQST), a meroterpenoid isolated from a marine sponge-derived fungus, has been reported to display antibacterial and antiviral activities. Here, we revealed that EQST displayed anti-obesity effects acting on adipose tissue through inhibiting adipogenesis in vitro and attenuating HFD-induced obesity in mice, doing so without affecting food intake, blood pressure or heart rate. We demonstrated that EQST inhibited the enzyme activity of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), a therapeutic target of obesity in adipose tissue. Anti-obesity properties of EQST were all offset by applying excessive 11β-HSD1's substrates and 11β-HSD1 inhibition through knockdown in vitro or 11β-HSD1 knockout in vivo. In the 11β-HSD1 bypass model constructed by adding excess 11β-HSD1 products, EQST's anti-obesity effects disappeared. Furthermore, EQST directly bond to 11β-HSD1 protein and presented remarkable better intensity on 11β-HSD1 inhibition and better efficacy on anti-obesity than known 11β-HSD1 inhibitor. Therefore, EQST can be developed into anti-obesity candidate compound, and this study may provide more clues for developing higher effective 11β-HSD1 inhibitors.
