Predictors of improvement in left ventricular systolic function after catheter ablation in patients with persistent atrial fibrillation complicated with heart failure.

AIMS: The current management of patients with atrial fibrillation (AF) and concomitant heart failure (HF) remains a significant challenge. Catheter ablation (CA) has been shown to improve left ventricular ejection fraction (LVEF) in these patients, but which patients can benefit from CA is still poorly understood. The aim of our study was to determine the predictors of improved ejection fraction in patients with persistent atrial fibrillation (PeAF) complicated with HF undergoing CA. METHODS AND RESULTS: A total of 435 patients with persistent AF underwent an initial CA between January 2019 and March 2023 in our hospital. We investigated consecutive patients with left ventricular systolic dysfunction (LVEF < 50%) measured by transthoracic echocardiography (TTE) within one month before CA. According to the LVEF changes at 6 months, these patients were divided into an improved group (fulfilling the '2021 Universal Definition of HF' criteria for LVEF recovery) and a nonimproved group. Eighty patients were analyzed, and the improvement group consisted of 60 patients (75.0%). In the univariate analysis, left ventricular end-diastolic diameter (P = 0.005) and low voltage zones in the left atrium (P = 0.043) were associated with improvement of LVEF. A receiver operating characteristic analysis determined that the suitable cutoff value for left ventricular end-diastolic diameter (LVDd) was 59 mm (sensitivity: 85.0%, specificity: 55.0%, area under curve: 0.709). A multivariate analysis showed that LVDd (OR = 0.85; 95% CI: 0.76-0.95, P = 0.005) and low voltage zones (LVZs) (OR = 0.26; 95% CI: 0.07-0.96, P = 0.043) were significantly independently associated with the improvement of LVEF. Additionally, parameters were significantly improved regarding the left atrial diameter, LVDd and ventricular rate after radiofrequency catheter ablation (all p < 0.05). CONCLUSIONS: The improvement of left ventricular ejection fraction (LVEF) occurred in 75.0% of patients. Our study provides additional evidence that LVDd < 59 mm and no low voltage zones in the left atrium can be used to jointly predict the improvement of LVEF after atrial fibrillation ablation.

Nerve Block Guided by Anatomic Landmarks Only Reduces Pain in Botulinum Toxin Type A Treatment for Glabellar and Forehead Wrinkles.

BACKGROUND: Botulinum toxin type A is widely used to treat glabellar and forehead wrinkles, but the pain caused by multiple injections often deters patients from receiving long-term treatment. Despite several methods used to alleviate this pain, consistency and effectiveness remain a challenge. Therefore, this study aimed to evaluate the effectiveness and safety of nerve block guided by anatomic landmarks only in reducing pain associated with botulinum toxin type A injections. PATIENTS AND METHODS: Between 2018 and 2022, the study enrolled 90 patients divided into 3 groups: the nerve block group (n = 30), the lidocaine cream group (n = 30), and the control group (n = 30). In the nerve block group, a landmarks-based technique was used to perform the nerve block. The study collected general information and comorbidities, and recorded pain at each point and time spent on preparation and treatment for each patient's forehead and glabellar area on each side. Patient-reported outcomes and complications were followed up at 2, 4, and 12 weeks after the injections. RESULTS: The nerve block group had significantly lower total pain scores in all regions compared to the lidocaine cream and control groups (P < 0.01). There were no significant differences in patient-reported outcomes between the groups at any follow-up point. Additionally, the complication rates related to injection were low and comparable among the 3 groups. CONCLUSIONS: Nerve block guided by anatomic landmarks only is a safe, effective, and consistent approach to reduce pain during botulinum toxin type A treatment for glabellar and forehead lines. This technique may offer advantages over other methods used to alleviate the pain associated with these injections.

Safety and efficacy of jaktinib in the treatment of Janus kinase inhibitor-naïve patients with myelofibrosis: Results of a phase II trial.

Myelofibrosis (MF) is associated with several constitutional symptoms. Currently, there are few therapeutic options for MF. Jaktinib, a novel, small-molecule inhibitor of JAK, is currently being studied for its potential to treat MF. This phase 2 trial investigated efficacy and safety of jaktinib in the treatment of MF patients. The primary end point was the proportion of patients with ≥35% reduction in spleen volume (SVR35, proportion of patients with ≥35% reduction in spleen volume) at week 24. The secondary end points included improvement of anemia, rates of symptom response, and safety profile. Between January 8, 2019 and August 29, 2020, 118 patients were recruited and treated with either jaktinib 100 mg BID or 200 mg QD. At week 24, 54.8% (34/62) of patients in the 100 mg BID group and 31.3% (15/48) in the 200 mg QD group achieved SVR35 (p = .0199). Jaktinib treatment increased hemoglobin level to ≥20 g/L in 35.6% (21/59) of patients with hemoglobin ≤100 g/L at baseline. The proportion of patients who achieved a ≥50% improvement in total symptom score at week 24 was 69.6% (39/56) in the BID group and 57.5% (23/40) in the QD group. The most common ≥ grade 3 hematological treatment-emergent adverse events (TEAEs; ≥ 10%) were anemia (100 mg BID: 24.2%, 200 mg QD: 28.8%), thrombocytopenia (16.7%, 11.5%), and neutropenia (3.0%, 11.5%). All non-hematological TEAEs were mild. These results indicate that jaktinib can shrink the spleen, improve anemia, and other clinical symptoms with good tolerability.

The effects and mechanisms of transcranial ultrasound stimulation combined with cognitive rehabilitation on post-stroke cognitive impairment.

OBJECTIVE: To investigate whether transcranial ultrasound stimulation (TUS) could improve post-stroke cognitive impairment (PSCI) and the potential mechanisms through which this can be achieved. METHOD: Sixty patients with PSCI were selected and randomly divided into a control and observation group, respectively, with 30 cases in each group. Conventional cognitive rehabilitation training combined with TUS intervention was conducted in the observation group, while conventional cognitive rehabilitation training and sham-TUS stimulation were given to patients in the control group. RESULTS: The Mini-Mental State Exam, Modified Barthel Index score, P300 latency, and wave amplitude, as well as the serum brain-derived neurotrophic factor (BDNF) levels, were significantly higher in both groups after treatment compared with those before treatment (P < 0.05), and were significantly higher in the observation group than in the control group (P < 0.05). After treatment, the observation group had significantly higher scores in executive, nomination, attention, language, and delayed recall compared with the control group (P < 0.05). CONCLUSION: Transcranial ultrasound stimulation combined with conventional cognitive rehabilitation therapy improved the PSCI condition with better efficacy than conventional cognitive rehabilitation therapy only. The mechanism involved may be correlated with the upregulation of BDNF and P300 induced by TUS.

[One case of hepatosplenic artery aneurysm with hepato-splenomesenteric trunk and literature review].

An asymptomatic 71-year-old woman was admitted to the hospital due to aneurysm of visceral artery. CT angiography revealed that she possessed a hepatosplenic artery aneurysm with hepatosplenomesenteric trunk anomaly. The aneurysm was big with diameter about 28 mm, and is very adjacent to the superior mensenteric artery. The neck of the aneurysm is wide (the diameter of the neck was 5.5-6.0 mm) and short (length of the proximal landing zone was about 2.0 mm). The patient received endovascular reconstruction of the hepatosplenic artery and coil embolization of the aneurysm, and got satisfactory result.

[Focus on the feeding behaviors inducing obesity and their regulation strategies].

Obesity has become a worldwide public health concern. In particular, obesity caused by excessive energy intake was widespread which has strong causal relationship with food preference behaviors. In this review, we would briefly talk about characteristics of feeding behaviors inducing obesity, as well as the possible neurophysiological mechanisms involved in food preference formation and development. Meantime, we would introduce some regulation strategies to deal with obesity which mainly based on the current feeding behaviors of the obese.

Intraclot recombinant tissue-type plasminogen activator reduces perihematomal edema and mortality in patients with spontaneous intracerebral hemorrhage.

The study aimed to investigate the impact of intraclot recombinant tissue-type plasminogen activator (rt-PA) on perihematomal edema (PHE) development in patients with intracerebral hemorrhage (ICH) treated with minimally invasive surgery (MIS) and the effects of intraclot rt-PA on the 30-day survival. We reviewed the medical records of ICH patients undergoing MIS between October 2011 and July 2013. A volumetric analysis was done to assess the change in PHE and ICH volumes at pre-MIS (T1), post-MIS (T2) and day 10-16 (T3) following diagnostic computed tomographic scans (T0). Forty-three patients aged 52.8±11.1 years with (n=30) or without rt-PA (n=13) were enrolled from our institutional ICH database. The median rt-PA dose was 1.5 (1) mg, with a maximum dose of 4.0 mg. The ratio of clot evacuation was significantly increased by intraclot rt-PA as compared with controls (77.9%±20.4% vs. 64%±15%; P=0.046). From T1 to T2, reduction in PHE volume was strongly associated with the percentage of clot evacuation (ρ=0.34; P=0.027). In addition, PHE volume was positively correlated with residual ICH volume at the same day (ρ ranging from 0.39-0.56, P<0.01). There was no correlation between the cumulative dose of rt-PA and early (T2) PHE volume (ρ=0.24; P=0.12) or delayed (T3) PHE volume (ρ=0.19; P=0.16). The 30-day mortality was zero in this cohort. In the selected cohort of ICH patients treated with MIS, intraclot rt-PA accelerated clot removal and had no effects on PHE formation. MIS aspiration and low dose of rt-PA seemed to be feasible to reduce the 30-day mortality in patients with severe ICH. A large, randomized study addressing dose titration and long-term outcome is needed.

A novel plant type, leaf disease and severity identification framework using CNN and transformer with multi-label method.

The growth of plants is threatened by numerous diseases. Accurate and timely identification of these diseases is crucial to prevent disease spreading. Many deep learning-based methods have been proposed for identifying leaf diseases. However, these methods often combine plant, leaf disease, and severity into one category or treat them separately, resulting in a large number of categories or complex network structures. Given this, this paper proposes a novel leaf disease identification network (LDI-NET) using a multi-label method. It is quite special because it can identify plant type, leaf disease and severity simultaneously using a single straightforward branch model without increasing the number of categories and avoiding extra branches. It consists of three modules, i.e., a feature tokenizer module, a token encoder module and a multi-label decoder module. The LDI-NET works as follows: Firstly, the feature tokenizer module is designed to enhance the capability of extracting local and long-range global contextual features by leveraging the strengths of convolutional neural networks and transformers. Secondly, the token encoder module is utilized to obtain context-rich tokens that can establish relationships among the plant, leaf disease and severity. Thirdly, the multi-label decoder module combined with a residual structure is utilized to fuse shallow and deep contextual features for better utilization of different-level features. This allows the identification of plant type, leaf disease, and severity simultaneously. Experiments show that the proposed LDI-NET outperforms the prevalent methods using the publicly available AI challenger 2018 dataset.

Phacogoniotomy versus phacotrabeculectomy for advanced primary angle-closure glaucoma with cataract: A randomized non-inferiority trial.

PURPOSE: To investigate the effectiveness and safety of phacogoniotomy versus phacotrabeculectomy (PVP) among patients with advanced primary angle-closure glaucoma (PACG) and cataracts. DESIGN: Multicenter, randomized controlled, non-inferiority trial. METHODS: A total of 124 patients (124 eyes) with advanced PACG and cataracts were enrolled, with 65 in the phacogoniotomy group and 59 in the phacotrabeculectomy group. Patients were followed up for 12 months with standardized evaluations. The primary outcome was the reduction in intraocular pressure (IOP) from baseline to 12 months postoperatively, of which a non-inferiority margin of 4 mmHg was evaluated. Secondary outcomes included the cumulative surgical success rate, postoperative complications, and changes in the number of glaucoma medications. RESULTS: After 12 months, phacogoniotomy demonstrated non-inferiority to phacotrabeculectomy in terms of IOP reduction, with mean IOP reductions of - 26.1 mmHg and - 25.7 mmHg (P = 0.383), respectively, from baseline values of around 40 mmHg. Both groups experienced a significant reduction in the mean number of medications used postoperatively (P < 0.001). The cumulative success rate was comparable between the groups (P = 0.890). However, phacogoniotomy had a lower rate of postoperative complications and interventions (12.3% and 4.6%) compared to phacotrabeculectomy (23.7% and 20.3% respectively). The phacogoniotomy group reported shorter surgery time (22.1 ± 6.5 vs. 38.8 ± 11.1 min; P = 0.030) and higher quality of life (EQ-5D-5 L) improvement at 12 months (7.0 ± 11.5 vs. 3.0 ± 12.9, P = 0.010) than the phacotrabeculectomy group. CONCLUSIONS: Phacogoniotomy was non-inferior to phacotrabeculectomy in terms of IOP reduction for advanced PACG and cataracts. Additionally, phacogoniotomy provided a shorter surgical time, lower postoperative complication rate, fewer postoperative interventions, and better postoperative quality of life.

[Subsequent retroperitoneoscopy for patients with previous ipsilateral retroperitoneal surgery].

OBJECTIVE: To evaluate the feasibility and clinical results of subsequent retroperitoneoscopic surgery for patients with previous ipsilateral retroperitoneal surgery through frank incision. METHODS: A total of 10 patents were selected for subsequent laparoscopic surgery through retroperitoneal approach. Among them, there were recurrent renal cysts (n = 4) including a history of open surgery (n = 1) and retroperitoneal surgery (n = 3) and nonfunctional kidneys (n = 6) including open nephropyelopolasty (n = 3), retroperitoneoscopic nephropyelopolasty (n = 1) and retroperitoneoscopic ureterolithotomy (n = 2). The mean surgical duration was (12-85) 38.6 months. All patients underwent retroperitoneoscopy. Decortication was performed for renal cysts and nephrectomy for nonfunctional kidneys. RESULTS: All operations were successfully performed with a mean surgical duration of 97 (40-185) minutes and a mean volume of blood loss 125 (20-460) ml. Among 4 cases with intraoperative peritoneal rupture, one case had renal cyst on ventral side. After enlargement, the procedure was performed through peritoneal cavity. The mean postoperative hospital stay was 5.6 (3-9) days. Nine patients received a mean follow-up period of 21.5 (3-47) months. All symptoms were relieved without any occurrence of postoperative complications. CONCLUSION: For patients with previous ipsilateral retroperitoneal surgery, retroperitoneoscopy may be feasible for properly selected cases.

[Quantifiable changes in HBeAg expression predict therapeutic efficacy of peg-interferon alfa-2a in patients with HBeAg-positive chronic hepatitis B].

OBJECTIVE: To investigate whether quantifiable changes in serum levels of hepatitis B e antigen (HBeAg) in response to 24 weeks of pegylated-interferon alfa-2a (Peg-IFN-a 2a) treatment are predictive of therapeutic efficacy at 48 weeks of treatment in HBeAg-positive chronic hepatitis B (CHB) patients and to investigate the efficacy of using an individualized antiviral treatment strategy. METHODS: Ninety-six HBeAg-positive CHB patients with detectable HBeAg at week 24 of Peg-IFN-a 2a treatment were categorized according to the quantitative change in HBeAg (vs. pre-treatment baseline): group A, HBeAg decline more than 2 log; group B, HBeAg decline between 1 - 2 log; group C, HBeAg decline less than 1 log, which was then randomly divided into two sub-groups: C1 and C2. Group A, B, and C1 patients continued the original therapy for an additional 24 weeks, while group C2 patients were supplemented with lamivudine (3TC + Peg-IFN-a 2a) for the additional 24 weeks of treatment. All patients underwent liver biopsy at the end of treatment (week 48), and HBV covalently-closed circular (ccc)DNA was quantified as a measure of therapeutic efficacy. A, B, and C1 between-group multiple comparisons were made by the Nemenyi test; C1 and C2 between-group comparison was made by the Mann-Whitney U test. The significance of between-group differences in decreased HBV cccDNA vs. HBeAg/anti-HBe seroconversion was made by the Chi-squared test. RESULTS: At week 48, the mean decrease of serum HBV cccDNA in each group was: A, 5.8 log10 copy/ml; B, 3.8 log10 copy/ml; C1, 2.8 log10 copy/ml; C2, 5.7 log10 copy/ml. Statistically significant differences were observed for group A vs. B and C1 (P less than 0.01) and C1 vs. C2 (P less than 0.01); however, the difference between group B and C1 did not reach statistical significance (P = 0.19). The mean decrease of HBeAg in each group was: A, 2.7 log10 S/CO; B, 1.9 log10 S/CO; C1, 0.9 log10 S/CO; C2, 1.6 log10 S/CO. Statistically significant differences were observed for group A vs. B and C1 (P less than 0.01) and C1 vs. C2 (P less than 0.01). The rate of patients who achieved undetectable HBV DNA in each group was: A, 87.5%; B, 34.5%; C1, 17.4%; C2, 85.0%. Statistically significant differences were observed for group A vs. B and C1 (P less than 0.01) and C1 vs. C2 (P less than 0.01). The HBeAg seroconversion rates were: A, 75.0%; B, 24.1%; C1, 13.0%; C2, 25.0%. Statistically significant differences were observed only for group A vs. B and C1 (P less than 0.01). Finally, group A achieved greater reduction in levels of cccDNA in liver tissues than B or C1 (P less than 0.01); however, the differences between B and C1 and between C1 and C2 did not reach statistical significance. CONCLUSION: CHB patients who showed an HBeAg decline of more than 2 log at week 24 of Peg-IFN-a 2a treatment had better treatment outcome at week 48 than those who showed HBeAg decline less than 2 log at week 24. Augmenting the Peg-IFN-a 2a treatment with 3TC can improve the clinical response. A change of quantifiable HBeAg at week 24 of Peg-IFN-a 2a treatment may be a useful predictor of therapeutic efficacy of a 48-week antiviral regimen.

The predictive value of left atrium epicardial adipose tissue on recurrence after catheter ablation in patients with different types of atrial fibrillation.

BACKGROUND: A growing body of evidence supports that the left atrium epicardial adipose tissue (LA-EAT) is related to the occurrence and recurrence of atrial fibrillation (AF). The relationship between LA-EAT and the recurrence after radiofrequency catheter ablation (RFCA) in patients with different types of AF is still unclear. This study aims to evaluate the predictive value of LA-EAT on the recurrence of AF after RFCA in patients with different types of AF. METHODS: 301 AF patients who underwent RFCA for the first time were divided into the paroxysmal atrial fibrillation (PAF) group (n = 181) and the persistent atrial fibrillation (PersAF) group(n = 120), which were followed up at 3, 6, and 12 months. All patients underwent left atrial computed tomography angiography (CTA) examination before the operation, and LA-EAT was measured using software (Advantage Workstation4.6, GE, USA). RESULTS: After a median follow-up of 10.7 months, 73/301 patients (24.25%) had a recurrence of AF, including 43 /120(35.83%) patients with PersAF and 30/181(16.57%) patients with PAF. In multivariable Cox regression analysis, LA-EAT volume (OR = 1.053;95%CI: 1.024-1.083, p < 0.001), attenuation (OR = 0.949;95%CI:0.911-0.988, p = 0.012) and left atrial diameter (LAD) (OR = 1.063;95%CI:1.002-1.127，p = 0.043) were independent risk factors for recurrence in patients with PersAF but not in patients with PAF. CONCLUSION: LA-EAT volume and attenuation are independent risk factors for recurrence after RFCA in patients with PersAF.

Effects of High-Intensity Interval Training and Combined High-Intensity Interval Training Programs on Cancer-Related Fatigue and Cancer Pain: A Systematic Review and Meta-analysis.

PURPOSE: This systematic review and meta-analysis assessed the effectiveness of high-intensity interval training (HIIT) alone and combined HIIT programs compared with usual care on cancer-related fatigue (CRF) and pain related to cancer or cancer-related treatments. METHODS: Articles published prior to January 2023 were searched in the following digital databases: PubMed, Cochrane Database of Systematic Reviews and Cochrane Controlled Clinical Trials (CENTRAL), Web of Science, Scopus and ScienceDirect. Randomized controlled trials were included that met the following criteria: (i) adult cancer patients and survivors (>18 yr old); (ii) HIIT or combined HIIT programs versus usual care; (iii) assessment of fatigue and pain. Cochrane tool was used for assessing Risk of Bias (RoB) and Review Manager (RevMan 5.2) was used for data analysis. RESULTS: Based on limited number (12) of studies included, we found HIIT and combined HIIT interventions have significant effect sizes on reducing both CRF (standardized mean difference, 0.63; 95% confidence interval, 0.42-0.84; P < 0.001) and cancer-associated pain (standardized mean difference, 0.44; 95% confidence interval, 0.25-0.63; P < 0.001). CONCLUSIONS: This systematic review and meta-analysis indicate that HIIT and combined HIIT programs can reduce CRF and pain.

Quercetin ameliorates nonalcoholic fatty liver disease (NAFLD) via the promotion of AMPK-mediated hepatic mitophagy.

The global incidence of nonalcoholic fatty liver disease (NAFLD) has been surging in recent years, however, no drug is currently approved to treat this disease. Quercetin, a natural flavonoid abundant in plants and fruits, has been reported to alleviate NAFLD, however, the exact molecular mechanism remains unclear. This study aims to further elucidate its potential mechanism of action. The beneficial effects and the underlying mechanism of quercetin in alleviating NAFLD were explored both in vitro and in vivo, by employing chemical inhibitors of autophagosomes (3-methyladenine, 3-MA), autolysosomes (chloroquine, CQ), AMPK (Compound C, CC) and SIRT1 (selisistat, EX-527). The levels of intracellular lipids, reactive oxygen species, mitochondria function, autophagy, and mitophagy were assessed by fluorescent labeling and examined using flow cytometry or confocal microscopy. Key protein expressions of autophagy, mitophagy, and inflammation were also determined. In vivo, quercetin was shown to dose-dependently effectively alleviate NAFLD, but intraperitoneal injection of 3-MA could block the beneficial effects of quercetin on body weight, liver weight, serum ALT/AST, hepatic ROS and inflammation. In vitro, quercetin could reduce intracellular lipids (Nile Red staining) and ROS/DHE accumulation, which could be also blocked by 3-MA or CQ. Furthermore, we found that CC could abrogate the protective effects of quercetin on lipid and ROS accumulation in vitro. Also, CC abolished the proautophagic and anti-inflammatory effects of quercetin, as shown by western blot determination and Lyso-Tracker labeling. Importantly, mitophagy, a specific form of mitochondria-targeted autophagy, was enhanced by quercetin, as demonstrated by PINK1/Parkin protein variation and immunofluorescence colocalization of autophagosomes and mitochondria, which could also be blocked by the intervention of CC. This study demonstrates that quercetin prevents NAFLD through AMPK-mediated mitophagy and suggests that promoting mitophagy via an upregulation of AMPK may be a promising therapeutic strategy against NAFLD.

The impact of public health education on people's demand for commercial health insurance: Empirical evidence from China.

Public health education is gaining significance globally, and it is important for managing health risks. This study empirically analyzed the effect of public health education on people's demand for commercial health insurance. And we used the fixed effects and the mediating effect models, and instrumental variables regression in our research based on panel data of 31 provinces (including municipalities and autonomous regions) in China from year 2009 to 2019. The findings show that public health education significantly increases people's demand for commercial health insurance, and this effect remains significant when considering endogeneity and robustness. We further analyzed and found that the increased demand for commercial health insurance is caused by health literacy, health risk perceptions and health risk attitudes. Through heterogeneity analysis, we found that there were significant differences in the effects of public health education in regions with different demographic and socioeconomic characteristics. We found that the effect of health education on promoting people's demand for commercial health insurance is more obvious in regions with high levels of urbanization, proportion of men, education, economic development, medical resources, and social medical insurance coverage. Governments are supposed to take further measures to enhance the effectiveness of public health education, develop high-quality commercial health insurance, and continuously improve health risk coverage.

[Effect of acupuncture at Huatuo Jiaji (EX-B2) combined with core muscle training on motor function of lower limbs in patients with hemiplegia after stroke].

OBJECTIVE: To observe the effect of acupuncture at Huatuo Jiaji (EX-B2) combined with core muscle training on motor function of lower limbs, balance function and core muscle in patients with hemiplegia after stroke. METHODS: A total of ninety-six patients with hemiplegia after stroke were randomly and equally divided into acupuncture, training and combination groups (n=32 cases in each). Patients of the acupuncture group were given acupuncture at the 5th, 7th, 9th and 11th chest vertebrae, and the 1st to 5th lumbar vertebrae of EX-B2. Patients in the training group received core muscle training. In the combination group, both acupuncture treatment and core muscle training were given to the patients. The treatment was conducted once daily, 5 times a week for 4 weeks. The Fugl-Meyer lower limb motor function score (FMA), Berg balance function scale (BBS), Barthel index (BI) and surface electromyography (sEMG) of the erector spinae and rectus abdominis were evaluated before and after treatment and during the follow-up period. RESULTS: Compared with the scores before the treatment, the FMA, BBS and BI scores were obviously increased after the treatment and during the follow-up period in the three groups respectively (P<0.05). After treatment and during the follow-up period, the root mean square (RMS) of erector spinae and rectus abdominis in the sitting position flexed 45° and extended 30° on the healthy and affected side were higher than those of the same side before treatment in the three groups (P<0.05). The therapeutic effect of combination of acupuncture at EX-B2 and core muscle training was obviously superior to that of single acupuncture or single training (P<0.05). Before the treatment, the RMS of erector spinae and rectus abdominis in the sitting position flexed 45° and extended 30° on the affected side were lower than those of the healthy side in the three groups (P<0.05), while there was no significant difference between the RMS of the erector spinae and rectus abdominis of the affected side and the healthy side in the comprehensive group after treatment and during the follow-up period (P＞0.05). CONCLUSION: Acupuncture at EX-B2 combined with core muscle training can significantly improve the balance function and lower limb motor function of patients with hemiplegia after stroke.

The effects of health behaviours and beliefs based on message framing among patients with chronic diseases: a systematic review.

OBJECTIVE: The effectiveness of integrating message framing into educational interventions to promote the health behaviour of patients with chronic diseases is still being debated in nursing research. The objective of this study was to assess the impact of educational interventions based on gain and loss frames on the health behaviours and beliefs of patients with chronic diseases and to identify the frame that achieves better outcomes. DESIGN: The systematic review was based on PRISMA guidelines for comprehensively searching, appraising and synthesising research evidence. DATA SOURCES: We searched the PubMed, Web of Science, PsycINFO and CINAHL databases for reports published from database inception until 26 March 2021. ELIGIBILITY CRITERIA: Intervention studies, published in English, with adult patients with chronic disease conditions, and with intervention contents involved in the implementation of message framing, were considered. The outcomes were health behaviours or beliefs, such as knowledge, self-efficacy, intention or attitudes. DATA EXTRACTION AND SYNTHESIS: Data extraction and entry were performed using a predesigned data extraction form and assessed independently by two reviewers using the Cochrane Collaboration Risk of Bias I. RESULTS: A total of 11 intervention studies were included. We found that educational intervention based on both gain and loss frames could enhance the positive effects of communication, and promote healthy behaviours and beliefs in patients with chronic disease. Many of the studies we included here showed the advantage of loss framing messages. Due to the limited number of articles included and without quantitative analysis, this result should be interpreted cautiously. CONCLUSIONS: Integrating message framing into health education might be a promising strategy to motivate patients with chronic disease to improve their health behaviours and beliefs. More extensive and well-designed trials are needed to support the conclusions and discuss the effective framing, moderators and mediators of framing. PROSPERO REGISTRATION NUMBER: CRD42021250931.

Effects of medical waste incineration fly ash on the promotion of heavy metal chlorination volatilization from incineration residues.

High contents of heavy metals and Cl are major challenges for incineration residue disposal. Classification by the Chinese government and the coronavirus disease 2019 pandemic have changed the characteristics of incineration residues, thereby increasing the difficulty of disposal. In this study, medical waste incineration fly ash (MWI FA) was proposed as an additive to promote chlorination volatilization of heavy metals from municipal solid waste incineration fly ash (MSWI FA) and medical waste incineration slag (MWI S). When the mixing ratio of MWI FA to MSWI FA was 1:3, the chlorination volatilization efficiencies of Cu, Zn, Pb, and Cd at 1000 °C for 60 min were 50.2%, 99.4%, 99.7%, and 97.9%, respectively. When MWI FA was mixed with MWI S at a ratio of 1:1, the chlorination volatilization efficiencies of Cu, Zn, Pb, and Cd at 1200 °C for 40 min were 88.9%, 99.7%, 97.3%, and 100%, respectively. Adding MWI FA can replenish Cl in MSWI FA and MWI S while increasing the surface area and forming pore structures by sublimation of NaCl and decomposition of CaSO4, or can reduce the melting point and viscosity by Na2O destroying the glass matrix. Therefore, MWI FA can be co-disposed with MSWI FA and MWI S respectively to enhance the chlorination volatilization of heavy metals.

Hoffa's fracture in a five-year-old child diagnosed and treated with the assistance of arthroscopy: A case report.

BACKGROUND: Hoffa's fracture is a coronal-oriented fracture of the femoral condyle. It is rarely observed in pediatric patients that isolated coronal fracture of the medial femoral condyle accompanies an intact lateral femoral condyle. Only a few cases involving Hoffa's fracture of the medial femoral condyle have been reported in patients with undeveloped skeletons. Such a fracture cannot be observed by routine imaging examinations, thus resulting in possible misdiagnosis and further treatment challenges. CASE SUMMARY: A 5-year-old boy with Hoffa's fracture of the medial femoral condyle suffered from right knee pain and severe swelling after being hit by a heavy object. The patient was misdiagnosed and initially treated in a local primary healthcare center. No improvement in his right knee's extension was observed following conservative treatment for 2 wk. The patient was transferred to our hospital, re-diagnosed using arthroscopy, and underwent open reduction and internal fixation. The therapeutic outcome was satisfactory with the screws removed 7 mo after fixation. At the final follow-up of 40 mo, the range of motion in the knee had recovered. There was no varus-valgus instability. CONCLUSION: Hoffa's fracture is rarely seen in children aged 5 years, let alone in the medial condyle, and can easily be misdiagnosed due to limited physical and imaging examinations. Suspected Hoffa's fracture in preschool children should be confirmed based on arthroscopic findings. Open reduction and internal fixation should be performed to protect the articular surface and prevent long-term complications.
