ABSTRACT

Perioperative protection of parathyroid function is the focus and difficulty of thyroid surgery and also a problem that surgeons must pay attention to. It can be divided into three stages: preoperative management, intraoperative management, and postoperative management. Preoperative management mainly evaluates thyroid and parathyroid function and timely and effective treatment plan adjustment when functional abnormalities are found. Intraoperative management includes identifying and protecting the parathyroid gland, assessing and protecting parathyroid blood flow, etc. Postoperative management includes assessment of postoperative parathyroid function, effective treatment, and follow-up. Among them, intraoperative management is the key. Familiarity with the anatomical structure is the basis of parathyroid function protection, and visual recognition is an essential skill. Secondly, reasonable selection of surgical methods and application of fine membrane dissection technology can avoid the collateral damage of energy instruments to the parathyroid gland and nourishing blood vessels, and finally, timely use of autologous transplantation technology. Using assistive techniques such as imaging can help accurately locate the parathyroid gland and assess its blood flow before surgery. Preoperative localization is even more critical for hyperparathyroidism due to the non-uniqueness and uncertainty of the location of the diseased glands. The objective of treatment is to remove the diseased parathyroid glands and protect normal parathyroid tissue. To standardize the functional protection of parathyroid gland during the perioperative period, domestic guidelines and expert consensus have proposed the "1+X" basic principle and the "1+X+1" general strategy of parathyroid gland protection, guiding to help reduce the incidence of parathyroid injury during thyroid surgery.

Both Mingshi Granules and placebo granules were taken orally, 1 bag each time, twice daily, 4 weeks of oral intake and 2 weeks of rest as 1 course of treatment, a total of 4 courses of treatment (24 weeks). Equivalent spherical lenses, best naked-eye distance visual acuity, ocular axis, corneal curvature K1, adjustment amplitude, traditional Chinese medicine (TCM) symptom scores, calculate the amount of progression of equivalent spherical lenses, were observed at the 12th and the 24th week of treatment, at the 36th week and 48th week of follow-up, resectively, the control rate of myopia progression was evaluated at the 24th week, and safety indexes were observed before treatment. ResultsThe amount of progression of equivalent spherical lenses was lower in the treatment group than in the control group at the 48-week follow-up (P<0.05). The control rate of myopia progression at 24 weeks after treatment in the treatment group was higher (57.60%, 72/125) than that in the control group (44.63%, 54/121) (P<0.05). The best naked-eye distance visual acuity at 36-week follow-up in the treatment group was higher than that in the control group (P<0.05). Equivalent spherical lenses were significantly lower in both groups at all observation time points compared with pre-treatment (P<0.05), and were higher in the treatment group than in the control group at the 48-week follow-up (P<0.05). The ocular axes of both groups were significantly higher at each observation time point after treatment and at follow-up compared with before treatment (P<0.05). The amount of eye axis growth in the treatment group was lower than that in the control group at 24 weeks after treatment and at the 48-week follow-up (P<0.05). Corneal curvature K1 was significantly lower in the treatment group at the 24th week of treatment compared to pre-treatment (P<0.05). The magnitude of adjustment in the treatment group was significantly higher at the 36-week follow-up and at the 48-week follow-up than before treatment (P<0.05). The scores of white/dark complexion, white coating thin pulse, fatigue and total TCM symptom scores of children in both groups at the 12th, 24th, 36th and 48th weeks of follow-up were significantly lower than those before treatment (P<0.05); the scores of blurred vision at the 24th and 36th weeks of follow-up were significantly lower than those before treatment (P<0.05); and the scores of blurred vision in the treatment group at the 48th week of follow-up were signi-ficantly lower than those before treatment (P<0.05).

ABSTRACT

BackgroundChronic insomnia is characterized by a prolonged and recurrent course. The efficacy of repeated transcranial magnetic stimulation (rTMS) as a physical therapy method to improve sleep quality remains inadequately supported by evidence, particularly regarding its relationship with personality traits. ObjectiveTo explore the efficacy and influencing factors of rTMS in the treatment of chronic insomnia, and to provide insights into its therapeutic potential. MethodA total of 46 patients who met the diagnostic criteria for chronic insomnia according to the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), and were treated at the Third Hospital of Mianyang from September 2022 to September 2023 were selected. Prior to treatment, participants underwent assessments using the Eysenck Personality Questionnaire (EPQ), Hamilton Depression Scale-17 item (HAMD-17) and Hamilton Anxiety Scale (HAMA). The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality before treatment, at the end of the second week of treatment and one week post-treatment. ResultsAt the end of the second week of treatment, patients exhibited significantly improved total PSQI score and subscale scores related to subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbance and daytime dysfunction (t=4.755~13.361, P<0.01), with 24 cases (54.35%) showing effective treatment outcomes. Multiple linear regression analysis showed that introverted and extroverted personality traits contributed significantly to the regression equation (B=0.317, P<0.01), explaining 29.90% of the total variation (R2=0.299). ConclusionrTMS treatment may effectively improve the sleep quality of patients with chronic insomnia, with its therapeutic effect appearing to associated with introverted and extroverted personality traits.

ABSTRACT

Objective: To determine the feasibility of using temporary permanent pacemaker (TPPM) in patients with high-degree atrioventricular block (AVB) after transcatheter aortic valve replacement (TAVR) as bridging strategy to reduce avoidable permanent pacemaker implantation. Methods: This is a prospective observational study. Consecutive patients undergoing TAVR at Beijing Anzhen Hospital and the First Affiliated Hospital of Zhengzhou University from August 2021 to February 2022 were screened. Patients with high-degree AVB and TPPM were included. Patients were followed up for 4 weeks with pacemaker interrogation at every week. The endpoint was the success rate of TPPM removal and free from permanent pacemaker at 1 month after TPPM. The criteria of removing TPPM was no indication of permanent pacing and no pacing signal in 12 lead electrocardiogram (EGG) and 24 hours dynamic EGG, meanwhile the last pacemaker interrogation indicated that ventricular pacing rate was 0. Routinely follow-up ECG was extended to 6 months after removal of TPPM. Results: Ten patients met the inclusion criteria for TPPM, aged (77.0±11.1) years, wirh 7 females. There were 7 patients with third-degree AVB, 1 patient with second-degree AVB, 2 patients with first degree AVB with PR interval>240 ms and LBBB with QRS duration>150 ms. TPPM were applied on the 10 patients for (35±7) days. Among 8 patients with high-degree AVB, 3 recovered to sinus rhythm, and 3 recovered to sinus rhythm with bundle branch block. The other 2 patients with persistent third-degree AVB received permanent pacemaker implantation. For the 2 patients with first-degree AVB and LBBB, PR interval shortened to within 200 ms. TPPM was successfully removed in 8 patients (8/10) at 1 month without permanent pacemaker implantation, of which 2 patients recovered within 24 hours after TAVR and 6 patients recovered 24 hours later after TAVR. No aggravation of conduction block or permanent pacemaker indication were observed in 8 patients during follow-up at 6 months. No procedure-related adverse events occurred in all patients. Conclusion: TPPM is reliable and safe to provide certain buffer time to distinguish whether a permanent pacemaker is necessary in patients with high-degree conduction block after TAVR.

ABSTRACT

BackgroundInsomnia disorder has become a common disease in the current society. Cognitive Behavior Therapy for Insomnia (CBTI) is one of the non-drug treatment methods for insomnia disorder, but relevant studies of its effect on sleep quality and cognitive function of patients with insomnia disorder are limited. ObjectiveTo explore the effects of CBTI on sleep quality and cognitive function in patients with insomnia disorder, so as to provide references for non-drug treatment of insomnia disorder. MethodsA total of 47 patients with insomnia disorder were recruited as the study subjects. They all met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) and have visited Sichuan Mental Health Center from January 2021 to October 2022. The patients underwent CBTI for 6 weeks. Before the treatment, depression and anxiety symptoms were assessed using Hamilton Depression Scale-24 item (HAMD-24) and Hamilton Anxiety Scale (HAMA). Sleep status and cognitive function were assessed using Pittsburgh Sleep Quality Index (PSQI) and Montreal Cognitive Assessment (MoCA) before and 6 weeks after the treatment. Spearman correlation analysis was used to examine the correlation between the reduction of PSQI score and the increase of MoCA score after treatment. ResultsAfter the 6-week treatment, the factor scores and total score of PSQI across 6 subscales (the sleep quality, sleep onset time, sleep time, sleep efficiency, sleep disorder and daytime dysfunction) were lower than those before the treatment, and the score differences were of statistical significance (t=5.569~15.290, P<0.01). Both factor and total scores of MoCA across 6 items (visuospatial and executive, naming, attention, language, abstraction and memory) were significantly higher than those before the treatment with score differences reaching statistical significance (t=-11.273~-4.277, P<0.01). Spearman correlation analysis demonstrated that there was a positive correlation between the decrease in PSQI total score and the increase in MoCA total score after the 6-week CBTI treatment (r=0.323, P=0.027). ConclusionCBTI may help improve sleep quality and cognitive function in patients with insomnia disorders. The improvement of sleep quality after CBTI intervention may be related to the improvement of cognitive function.

ABSTRACT

@#This study aims to investigate the effect of transmembrane protein angiotensin converting enzyme 2 (ACE2) on the prognosis of breast cancer and its potential mechanism.Public databases were used to analyze ACE2 expression and its relationship with clinicopathological features and prognosis of breast cancer patients, combined with in vitro experiments to analyze the mechanism of action and immune relevance of ACE2 in breast cancer.Results showed that the expression of ACE2 in breast cancer tissues was significantly lower than that in normal breast tissues, and that its expression was negatively correlated with age, M stage and N1mi stage of breast cancer patients (P < 0.05).Patients with Luminal type breast cancer with high ACE2 expression had poor prognosis, while in the triple-negative breast cancer (TNBC) subtype, ACE2 showed different prognostic significance.In addition, ACE2 is closely associated with the metabolic and immune microenvironment of tumor tissue.In vitro experiments have shown that ACE2 is lowly expressed in MDA-MB-231 cells and may inhibit cell progress by downregulating matrix metalloproteinase 2(MMP2).The results suggest that the low expression of ACE2 in breast cancer is closely associated with patient prognosis as well as metabolic and immune microenvironment, and that ACE2 may inhibit TNBC cell progress through the MMP2 pathway.

ABSTRACT

Tyrosine kinase inhibitors (TKIs) are a class of molecular targeted drugs that inhibit the activation of downstream signaling pathways by inhibiting oncogene-related receptor tyrosine kinases to exert anti-cancer effects. TKIs are superior to traditional chemotherapeutics in terms of selectivity, effectiveness and safety, and are widely used in the treatment of cancer. However, TKIs-induced liver injury is one of the difficult problems in its clinical application. In this article, relevant literatures from domestic and abroad are reviewed and the research progress in the classification, clinical application of TKIs and the mechanism of TKIs-induced liver injury are summarized. This review intends to provide a reference for further elucidating the mechanism of TKIs-induced liver injury, and seeking effective prevention and treatment methods.

ABSTRACT

@#Objective     To analyze the echocardiographic characteristics of above grade 3+ mitral regurgitation (MR) patients by 3D transesophageal echocardiography (3D-TEE) in transcatheter edge-to-edge repair (TEER) and compare the intervention rate of TEER treatment in patients with different risk stratification. Methods     We retrospectively analyzed the clinical data of 91 patients with above grade 3+ MR in Anzhen Hospital between June 2021 and April 2022. There were 45 males and 46 females aged 66.5±15.9 years. According to pathogenesis, the patients were divided into different anatomical groups and risk stratification groups. There were 34 patients in a simple degenerative group (simple DMR group), 28 patietns in a complex disease group (Complex group), 14 patients in a simple ventricular  functional reflux group (simple VFMR group), 9 patients in a simple atrial functional reflux group (simple AFMR group), and 6 patients in a mixed functional reflux group (mixed FMR group). All patients were examined with a unified standard of transthoracic echocardiography (TTE) and 3D-TEE to compare the characteristic three-dimensional structural changes of the mitral valve in each group. According to the three partition strategy of preoperative anatomical evaluation of TEER, the risk stratification was conducted for the enrolled patients, which was divided into three regions from light to heavy: green area, yellow area, and red area. TEER treatment intervention rate of patients with different risk stratification was calculated. Results     Ant leaf angle and post leaf angle were negative in the simple DMR and Complex groups, and non-planar angle, prolapse height and prolapse volume were higher than those of the other groups (P=0.000). Ant leaf angle and post leaf angle were positive in the VFMR group and the mixed FMR group. Anterior and posterior (AP) diameter of valve ring (P=0.036), tenting height and tenting volume were higher than those of other groups (P=0.000).  AP diameter, tenting height and tenting volume were changed mildly in patients with simple AFMR. MR patients in red and yellow zone achieved a 28.1% TEER intervention rate. Conclusion     Standardized TTE and TEE examinations are crucial for the qualitative and quantitative diagnosis of MR in the echo core-lab. 3D-TEE mitral valve parameter can help determine the exact pathogenesis of MR and to improve the interventional rate of challenging MR patients.

ABSTRACT

In this study, we explored the neural mechanism underlying impaired stereopsis and possible functional plasticity after strabismus surgery. We enrolled 18 stereo-deficient patients with intermittent exotropia before and after surgery, along with 18 healthy controls. Functional magnetic resonance imaging data were collected when participants viewed three-dimensional stimuli. Compared with controls, preoperative patients showed hypoactivation in higher-level dorsal (visual and parietal) areas and ventral visual areas. Pre- and postoperative activation did not significantly differ in patients overall; patients with improved stereopsis showed stronger postoperative activation than preoperative activation in the right V3A and left intraparietal sulcus. Worse stereopsis and fusional control were correlated with preoperative hypoactivation, suggesting that cortical deficits along the two streams might reflect impaired stereopsis in intermittent exotropia. The correlation between improved stereopsis and activation in the right V3A after surgery indicates that functional plasticity may underlie the improvement of stereopsis. Thus, additional postoperative strategies are needed to promote functional plasticity and enhance the recovery of stereopsis.

ABSTRACT

Objective: To explore the safety and efficacy of transcatheter aortic valve replacement (TAVR) using the "All in One" single-artery/vessel technique. Methods: This is a retrospective study. A total of 30 consecutive patients underwent TAVR using the single artery/vascular technique in Beijing Anzhen Hospital from August to December 2021 were included. Baseline clinical data, operative situation, postoperative outcomes, and incidence of adverse events during hospitalization and at one month post TAVR were analyzed. Results: Mean age was (72.6±9.7) years, 16 were male patients, STS score was (4.73±3.12)%. Four patients were diagnosed as isolated aortic regurgitation (all with tricuspid aortic valves), and 26 patients were diagnosed as aortic stenosis (AS), 10 of whom with tricuspid aortic valves and 16 of whom with bicuspid aortic valves. The single-vessel technique was applied in 3 aortic stenosis cases; the single-artery technique was applied in 27 cases. Echocardiography was performed immediately after procedure and results showed no or trace perivalvular leak in 27 cases and small perivalvular leak in 3 cases; the mean aortic transvalvular gradient of 26 AS patients decreased from (50.4±16.0) mmHg (1 mmHg=0.133 kPa) to (9.4±3.2) mmHg (P<0.001). The procedure time was (64.8±18.9) min. There were no intraoperative death, valve displacement, conversion to surgery, coronary artery occlusion in all 30 patients. There were no major cardiac adverse events such as myocardial infarction or stroke occurred during hospitalization or at follow-up. One-month follow-up echocardiography indicated prosthesis works well. The symptoms were significantly alleviated, and the Kansas City Cardiomyopathy Score (KCCQ score) of all patients increased from 48.1±18.4 to 73.5±17.6 (P<0.001). Conclusions: TAVR using the single artery/vessel technique is safe and feasible. This technique is related to reduced access complications and worthy of wide application.

ABSTRACT

Long chain non coding RNA (LncRNA) is widely involved in various biological processes such as intracellular chromatin modification, transcriptional regulation, nuclear transport, and protein function regulation, and is closely related to various key physiological functions such as immunity and metabolism in the body. NEAT1 (nuclear parapackle assembly transcript 1) is a newly discovered LncRNA, which is an important component of the nuclear substructural paraplaques. It has been proven to regulate downstream protein expression by binding to various miRNAs, thereby regulating the expression of inflammatory factors, epithelial mesenchymal transition, autophagy, apoptosis, proliferation, migration, and other biological processes, Its abnormal expression plays an important role in the pathogenesis of lung diseases such as asthma, chronic obstructive pulmonary disease, pneumonia, pulmonary fibrosis, and lung cancer, and is closely related to the prognosis of non-small cell lung cancer and the sensitivity of anti-tumor drugs. It is expected to become a new biological marker and therapeutic intervention target. This article mainly reviews the latest research progress on the role of NEAT1 in lung diseases.

ABSTRACT

@#In order to mask the bitterness of azithromycin (AZI) and individually regulate the drug release rate to reduce gastrointestinal irritation, immediate-release AZI-AmberliteTM IRP64/HPC and delayed-release AZI-AmberliteTM IRP69/RS100 were prepared by modifying with hydroxypropyl cellulose (HPC) and Eudragit RS100, respectively, and further combined to achieve controlled release.The drug loading and drug utilization rate of AZI-ion exchange resin complexes were measured; the structure of AZI-ion exchange resin complexes was characterized by differential scanning calorimetry and X-ray diffraction; and the wetting humidity, odor masking effects, in vitro dissolution and release behaviors were determined.The results showed that the formation of AZI-ion exchange resin complexes changed the original crystallization state of the drug, that the 2.5% HPC-modified AZI-AmberliteTM IRP64/HPC and the 0.5% RS100-modified AZI-AmberliteTM IRP69/RS100 demonstrated good taste masking effect, and that their combination in the drug content ratio of 13∶67 achieved the expected drug release behavior, i.e.rapid release of AZI in the first 10 min and smooth release in the later 6 h.These results indicated that the AZI-ion exchange resin complexes prepared by surface modification and their composites could mask the bitterness of AZI and realize the flexible adjustment of drug release rate, which lays the foundation for the research and development of new AZI preparations.

The included patients were divided into different groups according to the number of injured target organs, serum 25(OH)D level, and single target organ damage site. Two variables were correlated using the Pearson correlation analysis. The factors that affect target organ damage were analyzed using multivariate logistic regression analysis.Results:There were significant differences in age, course of the disease, serum 25(OH)D level, systolic blood pressure, and diastolic blood pressure among patients with different numbers of damaged target organs ( F = 16.95, 14.39, 14.95, 33.18, 20.88, all P < 0.001). There were significant differences in serum triacylglycerol level and 25(OH)D level among the patients who had different serum 25(OH)D levels ( F = 2.31, 178.48, both P < 0.05). There was a negative correlation between serum 25(OH)D levels and serum triacylglycerol levels. Serum 25(OH)D level was significantly lower in patients with damage to a single target organ heart, kidney, or carotid artery than in patients without target organ damage ( t = 9.24, 6.15, 6.09, all P < 0.05). There was no significant difference in serum 25(OH)D level between patients with damage to a single target organ ( P > 0.05). Older age, long course of disease, high systolic and diastolic blood pressure, and low serum 25(OH)D level were the independent risk factors for target organ damage (all P < 0.05). Conclusion:There is a correlation between serum 25(OH)D levels and target organ damage in older adult patients with essential hypertension. However, the evidence of vitamin D deficiency and target organ damage in essential hypertension is still insufficient, and further investigation is needed. This study is highly innovative and scientific.

ABSTRACT

Objective:To evaluate the effect of driving pressure (ΔP)-guided PEEP titration on lung injury in elderly patients undergoing robot-assisted radical prostatectomy (RARP).Methods:Forty-six American Society of Anesthesiologists physical status Ⅱ or Ⅲ patients, aged 65-80 yr, with body mass index of 19-28 kg/m 2, with Assess Respiratory Risk in Surgical Patients in Catalonia score assessed as medium to high risk, scheduled for elective RARP, were divided into control group (group C, n=23) and ΔP titration group (group D, n=23) using a random number table method.Volume-controlled mechanical ventilation was used after anesthesia induction and tracheal intubation.In group C, 5 cmH 2O was used to fix PEEP.In group D, the optimal PEEP was titrated after computer-controlled breathing and after establishing Trendelenburg position and pneumoperitoneum, the first titration started from 4 cmH 2O and increased by 1 cmH 2O every 4 min until ΔP reached the minimum value or PEEP increased to 12 cmH 2O, and the second titration was increased in increments as the method described above based on the optimal PEEP of the first titration.At 4 min after completion of the first PEEP titration (T 1, 4 min after mechanical ventilation with fixed PEEP in group C), 2 h after establishment of Trendelenburg position (T 2), 1 min after extubation (T 3) and 2 h after operation (T 4), serum concentrations of Clara cell protein (CC16), surfactant protein D (SP-D), soluble receptor for advanced glycation end-products (sRAGE) and soluble intercellular adhesion molecule-1 (sICAM-1). Pulmonary complications were assessed within 7 days after operation. Results:The serum concentrations of CC16, SP-D, sRAGE and sICAM-1 were significantly higher at T 2-4 than at T 1 in two groups ( P<0.05). Compared with group C, the serum concentrations of CC16, SP-D, sRAGE and sICAM-1 were significantly decreased at T 2-4 ( P<0.05), and no significant change was found in the incidence of pulmonary complications within 7 days after operation in group D ( P>0.05). Conclusions:ΔP-guided PEEP titration can reduce lung injury in elderly patients undergoing RARP.

ABSTRACT

@#Aortic stenosis (AS) is the most common primary valve lesion requiring surgery or transcatheter intervention in modern era. Its prevalence is rising rapidly as a consequence of the aging population. Transcatheter aortic valve replacement (TAVR) as a therapy option for older high-risk symptomatic severe AS patients has emerged and is currently extending its indications towards surgery intermediate- and low-risk subjects. Considering the common characteristics of frailty and high comorbidity among AS patients, cardiac rehabilitation (CR) has been proven to improve not only survival but also quality of life in previous reports. CR as a classⅠ recommendation in guidelines for the prevention and treatment of cardiovascular disease has been widely used in clinical practice. The purpose of this article is to sort out the current CR programs for TAVR patients in global medical management, and explore the CR optimization program fit for China medical model in post COVID-19 pandemic era.

ABSTRACT

Objective:To investigate the alteration of right ventricular function after catheter ablation in patients with persistent atrial fibrillation(PAF) and concomitant heart failure with preserved ejection fraction (HFpEF).Methods:The prospective observational study was performed in patients with HFpEF-PAF and undergoing first-time radiofrequency ablation procedures in the First Affiliated Hospital of Nanjing University between May to December 2019. Right ventricular functional parameters were measured before and 5 days, 1, 3, 6 and 12 months after the ablation by transthoracic echocardiography, respectively, including the right ventricular fractional area change (RVFAC), tricuspid annular plane systolic excursion(TAPSE), tricuspid annular diameter (TVAD), tricuspid annular peak systolic speed(TDI-S′) and longitudinal strain of right ventricular free wall (RVFLS). Meanwhile, routine ECG and Holter recordings were performed at each follow-up time point.Results:In this study, atrial fibrillation (AF) recurrence occurred in 4 patients at the 3rd month after ablation, and 7 patients failed to follow up due to the Covid-19. Finally, 19 patients were followed up for the evaluation of cardiac function after catheter ablation. Compared with pre-ablation, right ventricular structural and functional paramters(RVFAC, TAPSE, TVAD, TDI-S′, RVFLS) improved significantly at all stages of follow-up( all P<0.05). Patients with atrial fibrillation recurrence had lower RVFLS and TDI-S′ at the baseline( P=0.039, P=0.019). Conclusions:Right ventricular function could improve in HFpEF-PAF patients who maintain sinus rhythm after radiofrequency ablation.
