Objective:To investigate the clinical value of tissue Doppler echocardiography in the evaluation of left ventricular function in patients with pregnancy-induced hypertension.Methods:This is a case-control study, including 100 patients with pregnancy-induced hypertension who received treatment at the Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from May 2019 to May 2022, and an additional 100 healthy pregnant women who underwent physical examination during the same period. All participants underwent two-dimensional echocardiography, pulsed Doppler echocardiography, and tissue Doppler echocardiography. Ultrasound parameters related to left ventricular morphology and function were collected from all participants. The ultrasound parameters related to left ventricular morphology and function between patients with different types of pregnancy-induced hypertension and healthy controls were compared. The correlation between left ventricular function ultrasound parameters and serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels was investigated.Results:Patients with pregnancy-induced hypertension, patients with mild preeclampsia, patients with severe preeclampsia, and healthy controls demonstrated differences in interventricular septum thickness during diastole [(10.24 ± 1.18) mm, (11.39 ± 1.24) mm, (11.57 ± 1.29) mm, (8.81 ± 0.95) mm], left ventricular end-diastolic diameter [(47.31 ± 2.81) mm, (49.82 ± 2.89) mm, (52.03 ± 2.94) mm, (46.82 ± 2.76) mm], left ventricular posterior wall thickness [(9.73 ± 1.06) mm, (10.62 ± 1.13) mm, (11.75 ± 1.21) mm, (8.96 ± 0.97) mm], left ventricular inner diameter [(32.82 ± 2.34) mm, (35.48 ± 2.39) mm, (36.04 ± 2.45) mm, (30.41 ± 2.27) mm], and left ventricular mass index [(98.41 ± 7.83) g/m 2, (105.73 ± 8.26) g/m 2, (108.63 ± 8.57) g/m 2, (96.59 ± 7.69) g/m 2]. All of these parameters showed significant differences between patients with different types of pregnancy-induced hypertension and healthy controls ( F = 13.47, 12.61, 16.59, 13.26, 19.73, all P < 0.001). Significant differences were also observed in echocardiographic indices of left ventricular function such as peak velocity ratio of E and A waves, systolic motor amplitude, early peak diastolic velocity to late peak diastolic velocity, and Tei index between patients with different types of pregnancy-induced hypertension and healthy controls ( F = 12.84, 11.27, 14.64, 21.43, all P < 0.001). In patients with pregnancy-induced hypertension, peak velocity ratio of E and A waves, systolic motor amplitude, and early peak diastolic velocity to late peak diastolic velocity were moderately negatively correlated with serum NT-proBNP level ( r = -0.56, -0.43, -0.54, P = 0.029, 0.042, 0.031), while Tei index showed a positive correlation with serum NT-proBNP level ( r = 0.77; P = 0.003). Conclusion:Two-dimensional echocardiography, pulsed Doppler echocardiography combined with tissue Doppler echocardiography can be used to effectively evaluate the changes in left ventricular structure and function in patients with different types of pregnancy-induced hypertension. Monitoring the Tei index using tissue Doppler echocardiography can accurately reflect myocardial injury and functional changes, which has a great clinical application value.

Anti-seizure medications (ASMs) are the main therapy for epilepsy.There are many kinds of ASMs with complex mechanism of action, so it is difficult for pharmacists to examine prescriptions.This paper put forward some suggestions on the indications, dosage forms/routes of administration, appropriateness of usage and dosage, combined medication and drug interaction, long-term prescription review, individual differences in pathophysiology of children, and drug selection when complicated with common epilepsy, for the reference of doctors and pharmacists.

Since the implementation of the Measures for the Management of Radiation Workers’ Occupational Health in November 2007, it has played an extremely important role in protecting the occupational health of radiation workers. There are more than 700 000 radiation workers in about 100 000 workplaces with potential radiation exposure, as well as a large number of miners exposed to high levels of radon. As the radiation health monitoring project suggests, measures of occupational health management such as personal dose monitoring and occupational health examination of radiation workers have been widely implemented and achieved good results in the protection of radiation workers. However, the risks of chromosomal aberration and specific turbidity of the eye lens of radiation workers have increased in high-risk positions such as interventional radiology, nuclear medicine, and industrial flaw detection. The control of high radon exposure in miners needs to be strengthened. It is necessary to adapt to the new situation in view of new challenges and actively promote the revision of the Measures for the Management of Radiation Workers’ Occupational Health, so as to further improve the occupational health management of radiation workers in China.

Mandibular defects caused by injuries, tumors, and infections are common and can severely affect mandibular function and the patient's appearance. However, mandible reconstruction with a mandibular bionic structure remains challenging. Inspired by the process of intramembranous ossification in mandibular development, a hierarchical vascularized engineered bone consisting of angiogenesis and osteogenesis modules has been produced. Moreover, the hierarchical vascular network and bone structure generated by these hierarchical vascularized engineered bone modules match the particular anatomical structure of the mandible. The ultra-tough polyion complex has been used as the basic scaffold for hierarchical vascularized engineered bone for ensuring better reconstruction of mandible function. According to the results of in vivo experiments, the bone regenerated using hierarchical vascularized engineered bone is similar to the natural mandibular bone in terms of morphology and genomics. The sonic hedgehog signaling pathway is specifically activated in hierarchical vascularized engineered bone, indicating that the new bone in hierarchical vascularized engineered bone underwent a process of intramembranous ossification identical to that of mandible development. Thus, hierarchical vascularized engineered bone has a high potential for clinical application in mandibular defect reconstruction. Moreover, the concept based on developmental processes and bionic structures provides an effective strategy for tissue regeneration.

Onodera prognostic nutrition index (OPNI) is a simple and effective parameter. It is calculated by serum albumin level and peripheral blood lymphocyte count. Initially, OPNI is used to assess preoperative nutritional status and surgical risk. In recent years, researchers have found that OPNI is related to the prognosis of many tumors. Simple and accurate prognosis evaluation can help to select treatment methods for digestive system malignant tumors, determine the best pre-operative treatment time and operation time, and improve the survival rate of patients with diges-tive system malignant tumors. The authors review the related literatures at home and abroad, and summarize the research advances in the prognostic value of OPNI for malignant tumors of digestive systems.

Objective:To investigate the effectiveness of radiomics model based on preoperative ultrasound in predicting disease-free survival (DFS) in patients with triple negative breast cancer (TNBC) from multicenter data.Methods:A total of 418 patients with TNBC between July 2012 and December 2016 were consecutively recruited for this study from three different institutions including the First Affiliated Hospital of Nanjing Medical University, Jiangsu Province Hospital of Chinese Medicine and General Hospital of Eastern Theater Command. In the training cohort ( n=271) from institution 1(the First Affiliated Hospital of Nanjing Medical University), least absolute shrinkage and selection operator (LASSO) logistic regression algorithm was employed to select recurrence-related radiomics features and build a signature derived from the grayscale US images. The relationship between the radiomics score (Rad-score) and DFS was evaluated. Univariate and multivariate cox regression were utilized to identify the significant radiomics features and clinical-pathologic variables, which were integrated into a radiomics nomogram. An independent external cohort ( n=147) from the other two institutions was validated for evaluating the calibration and discrimination of the predictive nomogram. Results:Higher Rad-score was an independent risk predictor of worse DFS in two cohorts (both P<0.05). The radiomics model, comprising axillary lymph node status, Ki-67 index and radiomics signature, showed better prognostic performance ( P<0.01) than those of the clinical-pathologic model or tumor node metastasis (TNM) staging system with the concordance index (C-index) of 0.75 (95% CI=0.72-0.78) and 0.73(95% CI=0.71-0.75) in the training and validation cohorts respectively. Furthermore, the calibration curves achieved satisfactory agreement and the decision curves further confirmed the clinical utility of the radiomics nomogram. Conclusions:The US-based radiomics signature is a powerful predictor for the assessment of DFS in patients with TNBC. Moreover, the proposed radiomics model integrating the optimal radiomics signature and clinical-pathologic data could improve personalized DFS estimation.

Electroencephalogram (EEG) has been an important tool for scientists to study epilepsy and evaluate the treatment of epilepsy for half a century, since epilepsy seizures are caused by the diffusion of excessive discharge of brain neurons. This paper reviews the clinical application of scalp EEG in the treatment of intractable epilepsy with vagus nerve stimulation (VNS) in the past 30 years. It mainly introduces the prediction of the therapeutic effect of VNS on intractable epilepsy based on EEG characteristics and the effect of VNS on EEG of patients with intractable epilepsy, and expounds some therapeutic mechanisms of VNS. For predicting the efficacy of VNS based on EEG characteristics, EEG characteristics such as epileptiform discharge, polarity of slow cortical potential changes, changes of EEG symmetry level and changes of EEG power spectrum are described. In view of the influence of VNS treatment on patients' EEG characteristics, the change of epileptiform discharge, power spectrum, synchrony, brain network and amplitude of event-related potential P300 are described. Although no representative EEG markers have been identified for clinical promotion, this review paves the way for prospective studies of larger patient populations in the future to better apply EEG to the clinical treatment of VNS, and provides ideas for predicting VNS efficacy, assessing VNS efficacy, and understanding VNS treatment mechanisms, with broad medical and scientific implications.

Objective:To explore the significance of multimodal monitoring in the monitoring and treatment of neurocritical care patients.Methods:104 neurocritical care patients admitted to the department of Critical Care Medicine of Fujian Provincial Hospital from March 2019 to January 2020 were enrolled. Patients were randomly assigned into two groups, with 52 in each group. In the routine monitoring treatment group, heart rate, blood pressure, respiratory rate and the changes in consciousness and pupils were monitored after operation. The patients were treated with routine medicine to reduce intracranial pressure (ICP), maintain proper cerebral perfusion pressure (CPP), balance fluid intake and output, and maintain the airway clear. Patients in the multimodal monitoring treatment group were treated with invasive ICP monitoring, ultrasound to assess brain structure, ultrasound to measure optic nerve sheath diameter (ONSD), transcranial color doppler (TCCD), internal jugular venous blood oxygen saturation monitoring, near-infrared spectroscopy (NIRS), non-invasive cerebral blood oxygen saturation monitoring and quantitative electroencephalogram monitoring. According to the monitoring results, the patients were given targeted treatment with the goal of controlling ICP and improving brain metabolism. The length of intensive care unit (ICU) stay, the incidences of neurological complications (secondary cerebral infarction, cerebral hemorrhage, high intracranial pressure, etc.), and the incidences of poor prognosis [6 months after the onset of Glasgow outcome score (GOS) 1 to 3] were compared between the two groups. Spearman rank correlation analysis of the correlation between invasive ICP and the ICP value which was calculated by TCCD. The receiver operating characteristic (ROC) curve of invasive ICP and pulsatility index of middle cerebral artery (PI MCA) were used to predict poor prognosis. Results:The length of ICU stay in the multimodal monitoring treatment group was significantly shorter than that of the routine monitoring treatment group (days: 6.27±3.81 vs. 9.61±5.09, P < 0.01), and the incidence of neurological complications was significantly lower than that in the routine monitoring treatment group (9.62% vs. 25.00%, P < 0.05). In the multimodal monitoring treatment group, 37 cases had a good prognosis and 15 cases had a poor prognosis, while the routine monitoring treatment group had a good prognosis in 27 cases and a poor prognosis in 25 cases. The incidence of poor prognosis in the multimodal monitoring treatment group was lower than that of the routine monitoring treatment group (28.85% vs. 48.08%, P < 0.05). In the multimodal monitoring treatment group, the invasive ICP and PI MCA of patients with good prognosis were significantly lower than those of patients with poor prognosis [invasive ICP (mmHg, 1 mmHg = 0.133 kPa): 16 (12, 17) vs. 22 (20, 24), PI MCA: 0.90±0.33 vs. 1.39±0.58, both P < 0.01]. There was no significant difference in resistance index of the middle cerebral artery (RI MCA) between the good prognosis group and the poor prognosis group (0.63±0.12 vs. 0.66±0.15, P > 0.05). There was a positive correlation between the invasive ICP and the ICP value which was calculated by TCCD ( r = 0.767, P < 0.001). ROC curve analysis showed that the area under ROC curve (AUC) of invasive ICP for poor prognosis prediction was 0.906, the best cut-off value was ≥ 18 mmHg, the sensitivity was 86.49%, and the specificity was 86.67%. The AUC of PI MCA for poor prognosis prediction was 0.759, the best cut-off value was ≥ 1.12, the sensitivity was 81.08%, and the specificity was 60.00%. The AUC of invasive ICP was greater than PI MCA ( Z = 2.279, P = 0.023). Conclusion:Comprehensive analysis of multimodal monitoring indicators for neurocritical care patients to guide clinical treatment can reduce the length of hospital stay, and reduce the risk of neurosurgery complications and disability; invasive ICP can predict poor prognosis of neurocritical care patients.

Objective:This study aimed to explore the efficacy and safety of rituximab combined with short-course and intensive regimens in the treatment of adult patients with Burkitt leukemia.Methods:The clinical data of 11 Burkitt leukemia patients in our hospital from January 30, 2006, to September 12, 2018, were collected. The clinical details, complete remission (CR) rate, overall survival (OS) , relapse-free survival (RFS) , and adverse events were evaluated.Results:The median age of 11 patients was 34 (15-54) years, of which six were males and five were females (M∶F, 1.2∶1) . The median white blood cell (WBC) count was 12.28 (2.21-48.46) ×10 9/L, and the median blast percent of peripheral blood and bone marrow were 40% (3%-76%) and 84.0% (29.5%-94.5%) , respectively. Ten patients were administered with rituximab combined with a short-course and intensive regimens, and two patients underwent autologous hematopoietic stem cell transplantation following consolidation chemotherapy. The CR rate after one cycle of induction therapy was 100%, the four-year OS was 90%, and RFS was 90%. Out of the ten treated patients, only one patient suffered from tumor lysis syndrome during the induction chemotherapy. Consequently, renal function recovered after hemodialysis and other treatments. The regimen is safe with no treatment-related deaths. Conclusions:Rituximab combined with short-course and intensive chemotherapy regimens is effective and well-tolerated in adult Burkitt leukemia.
